The configuration and arrangement of the bus bar 315 will be described later. 5 is a cross-sectional view taken along the line V-V in FIG. 2, but illustrations of members (the heater core 36, an evaporator, and the like) inside the air conditioning casing 31 are omitted.

  The rear seat outlet pipe 32 is a member fixed to the second main member 312 and is connected to a rear seat outlet near the rear seat. The blown air that has entered the passage in the rear seat outlet pipe 32 from the opening for the rear seat in the air-conditioned space is blown out from the rear seat outlet to the rear seat in the passenger compartment after passing through the rear seat outlet pipe 32. The

  The heater core 36 is inserted into the air conditioning casing 31 and arranged in the air conditioned space. Hot water sent from the hot water pipe 33 flows into the heater core 36. The hot air flowing through the hot water pipe 33 and the blown air passing through the surface of the hot water pipe 33 in the air-conditioned space exchange heat with each other, whereby the blown air is heated. The heater core 36 corresponds to the heating unit.

  An evaporator is arrange | positioned in an air-conditioning space and heat-exchanges the refrigerant | coolant which distribute | circulates the inside of an evaporator, and the ventilation air which passes along the surface of an evaporator.

  Inside the air-conditioning casing 31, the air-conditioned space is divided into four parts by the partition walls 312a and 312b: a driver-seat upper air-conditioned space, a driver-seat lower air-conditioned space, a passenger-seat upper air-conditioned space, and a passenger-seat lower air-conditioned space. .

  The partition 312a is a flat plate perpendicular to the vehicle width direction. The partition 312b is a plate perpendicular to the partition 312a.

  The air mix door group described above includes an air mix door disposed in the driver's seat upper conditioned space, an air mix door disposed in the driver's seat lower conditioned space, and an air mix door disposed in the passenger's seat upper conditioned space; And an air mix door disposed in the passenger seat lower air-conditioned space.

  First, the driver's seat upper air-conditioned space will be described. The air mix door in the driver seat upper conditioned space is disposed on the upstream side of the air flow of the heater core 36. This air mix door adjusts the air volume ratio (that is, the warm air ratio) of the air volume of the blown air passing through the hot air passage to the blown air passing through the cold air bypass passage.

  A portion of the driver seat upper space on the downstream side of the air flow of the evaporator includes a cold air bypass passage, a hot air passage, and an air mix space. The cold air bypass passage is a passage through which the blown air that has passed through the evaporator flows around the heater core 36. The warm air passage is a passage in which the heater core 36 is disposed. The air mix space is a passage disposed in the downstream portion of the air flow in both the air conditioning space hot air passage and the cold air bypass passage. The air passing through the hot air passage and the air passing through the cold air passage mix with each other in the air mix space. The blown air mixed in the air mix space is blown out into the passenger compartment.

  The above is the description of the driver's seat upper air-conditioned space. The driver seat lower conditioned space, the passenger seat upper conditioned space, and the passenger seat lower conditioned space have the same configuration as the driver seat upper conditioned space. In other words, the air mix door, the cold air bypass passage, the hot air passage, and the air mix space are divided into the driver's seat upper conditioned space, the driver seat lower conditioned space, the passenger seat upper conditioned space, and the passenger seat lower conditioned space, One set is provided in the same arrangement.

  In the following, as shown in FIG. 5, the air mix space in the driver's seat upper conditioned space is referred to as air mix space 60DU, the air mix space in the driver seat lower conditioned space is referred to as air mix space 60DL, and the passenger seat upper conditioned space. The air mix space is referred to as an air mix space 60PU, and the air mix space under the passenger seat air conditioning space is referred to as an air mix space 60PL.

  Of the plurality of defroster openings described above, a part opens to the air mix space 60DU, another part opens to the air mix space 60DL, and another part opens to the air mix space 60PU. Furthermore, another part opens to the air mix space 60PL.

Of the plurality of rear seat openings described above, a part opens to the air mix space 60DL, and another part opens to the air mix space 60PL.

  The refrigeration cycle is a device that repeatedly compresses, condenses, decompresses, and expands the refrigerant, and exchanges heat between the refrigerant and the blown air. The expansion valve 35, the heater core 36, and the evaporator described above are part of the air conditioning unit 3 and part of the refrigeration cycle. The refrigeration cycle further includes a compressor and an outdoor condenser.

  The compressor sucks and blows out the refrigerant. An outdoor condenser is connected to the refrigerant downstream side of the compressor. The outdoor condenser exchanges heat between the refrigerant and the outside air, thereby removing heat from the refrigerant and condensing the refrigerant. An expansion valve 35 is connected to the refrigerant downstream side of the outdoor condenser. Due to the action of the compressor, a pressure difference is generated between the refrigerant upstream side and the refrigerant downstream side of the expansion valve 35. Therefore, the refrigerant passing through the expansion valve 35 is decompressed and expands. An evaporator is connected to the refrigerant downstream side of the expansion valve 35. Heat is exchanged between the refrigerant flowing through the evaporator and the blown air passing through the surface of the evaporator. Thereby, the refrigerant takes heat from the blown air and expands, and the blown air is cooled. The refrigerant downstream side of the evaporator is connected to the refrigerant upstream side of the compressor.

  The actuator unit 41 has a servo motor that drives a mode door corresponding to a plurality of face openings and a plurality of foot openings in the mode door group. The actuator unit 42 includes a servo motor that drives an air mix door disposed in the passenger seat upper air-conditioned space. The actuator unit 43 has a servo motor that drives an air mix door disposed in the passenger seat lower air-conditioned space.

The actuator unit 48 has a servo motor that drives an air mix door disposed in the air conditioning space below the driver's seat.

  In addition, each of the actuator units 41 to 48 includes a casing, a communication unit, and a control unit. The casing accommodates a servo motor, a communication unit, and a control unit belonging to the same actuator unit. The communication unit is an interface circuit for communicating with the air conditioning control ECU via the bus bar 315. The control unit is a control circuit that controls servo motors belonging to the same actuator unit.

  The actuator units 41, 42, 43, 44 are fixed to the outer surface of the left side wall WL of the air conditioning casing 31. The actuator units 45, 46, 47, 48 are fixed to the outer surface of the right side wall WR of the air conditioning casing 31. The left side wall WL, the right side wall WR, the rear side wall WB, and the front side wall WF are walls that cover the air-conditioned space from the left side, the right side, the rear side, and the front side, respectively, and constitute main members 311 to 314.

  The rear side wall WB is in a range surrounded by both ends of the rotating shaft of the air distribution door. Therefore, the rear side wall WB is a wall extending from one end of the rotating shaft of the air distribution door to the other end. The rear side wall WB provided in the range surrounded by the both ends of the air distribution door has a lower rigidity as the area increases, and further decreases in rigidity due to the influence of the thinning. Therefore, if the bus bar 315 is not provided, resonance easily occurs due to the influence of vibration sources such as the actuators 41 to 48.

  The air conditioning control ECU controls the operation of the above-described compressor, blower 22, and actuator units 41 to 48, thereby controlling the temperature, air volume, and the like of the blown air blown out from the air-conditioned space into the vehicle interior.

  Here, the configuration and arrangement of the bus bar 315 will be described in detail with reference to FIGS. 3, 4, 5, 6, 7, and 7. First, the material of the bus bar 315 will be described. The bus bar 315 is a conductive member having a higher elastic modulus and Young's modulus than any part of the first main member 311, the second main member 312, the third main member 313, and the fourth main member 314. Therefore, of course, of the main members 311 to 313, the contact surface 31x with the bus bar 315 and a part of its vicinity have lower elastic modulus and Young's modulus than the bus bar 315. Therefore, the air conditioning casing 31 can be reinforced by the bus bar 315. In addition, the contact surface 31x is all surfaces which contact the bus bar 315 among main members.

  Further, in a cross section including both of the main member and the bus bar 315 (for example, the cross section of FIGS. 6 and 7), the bending rigidity of the bus bar 315 with respect to any axis parallel to the cross section is Higher than bending stiffness. By doing in this way, the reinforcement effect of the air-conditioning casing 31 by the bus-bar 315 can be heightened more.

  Specifically, the bus bar 315 may be generated by punching from a punched material of a brass plate. The bus bar 315 is embedded and fixed to the main members 311 to 313 by insert molding, and is fixed to the main members 311 to 313. That is, a part of the bus bar 315 is formed integrally with the main member 311, the other part of the bus bar 315 is formed integrally with the main member 312, and the remaining part of the bus bar 315 is formed integrally with the main member 313. As a result, the bus bar 315 is integrated with the main members 311 to 313.

  Next, the arrangement of the bus bars 315 will be described. As shown in FIGS. 3 to 7, the bus bar 315 is embedded in the rear side wall WB, the right side wall WR, and the left side wall WL of the main members 311, 312, and 313. Since the contact area between the bus bar 315 and the main members 311 to 313 is increased, the reinforcing effect of the air conditioning casing 31 by the bus bar 315 can be enhanced.

  Specifically, as shown in FIGS. 2, 5, and 7, the bus bar 315 extends on the rear side wall WB from the right end to the left end so as to intersect in the vertical direction (more specifically, orthogonally). Yes.

  Further, as shown in FIG. 3, the bus bar 315 extends forward from the rear end on the left side wall WL, and then branches to extend so as to approach the actuator units 41, 42, 43, 44.

  The bus bar 315 is exposed to the outside of the main member at the contact portion between the actuator unit 41 and the air conditioning casing 31. The communication unit of the actuator unit 41 is connected to the bus bar 315 from the exposed portion via a wire harness (not shown). Therefore, the communication unit of the actuator unit 41 can communicate via the bus bar 315. The same applies to the actuator units 42, 43, and 44.

  Further, as shown in FIG. 4, the bus bar 315 extends forward from the rear end on the right side wall WR, and then branches to extend so as to approach the actuator units 45, 46, 47, and 48.

  The bus bar 315 is exposed to the outside of the main member at the contact portion between the actuator unit 45 and the air conditioning casing 31. The communication unit of the actuator unit 45 is connected to the bus bar 315 from the exposed portion via a wire harness (not shown). Therefore, the communication unit of the actuator unit 45 can communicate via the bus bar 315. The same applies to the actuator units 46, 47, and 48.

  As described above, the communication units of the actuator units 41 to 48 use the same bus bar 315 as a communication bus. For example, when the bus bar 315 is used as a LIN bus, one of the three bus bars 315 may be a ground line, one may be a 12V line, and the remaining one may be a signal line. The bus bar 315 is connected to the air conditioning control ECU via a route (not shown). Therefore, an electric signal is transmitted from the air conditioning control ECU via the bus bar 315, and each of the actuator units 41 to 48 moves according to the electric signal. An electrical signal may be transmitted from the communication unit to the air conditioning control ECU via the bus bar 315.

  Note that power is supplied to each actuator unit 41 to 48 from a vehicle battery via a wire harness other than the bus bar 315.

  Here, the left side wall WL, the right side wall WR, the rear side wall WB, and the left side wall WL of the air conditioning casing 31 will be further described. First, the virtual rectangular parallelepiped 100 is defined. The virtual rectangular parallelepiped 100 is the smallest virtual rectangular parallelepiped that can accommodate the entire main members 311 to 314. In the present embodiment, two of the six surfaces of the virtual rectangular parallelepiped 100 are orthogonal to the vertical direction, the other two surfaces are orthogonal to the horizontal direction, and the remaining two surfaces are orthogonal to the front-rear direction.

  Therefore, the front side wall WF is closest to the front surface of the six surfaces. Further, the rear side wall WB is closest to the rear side surface among the six surfaces. The right side wall WR is closest to the right side surface among the six surfaces. The left side wall WL is closest to the left side surface among the six surfaces.

  Further, the front side wall WF surrounds the air-conditioned space from the front side of the six surfaces. In addition, the rear side wall WB surrounds the air-conditioned space from the rear side of the six surfaces. The right side wall WR surrounds the air-conditioned space from the right side of the six surfaces. The left side wall WL surrounds the air-conditioned space from the left side of the six surfaces. In the present embodiment, among the six surfaces, the front surface and the rear surface are surfaces having the largest area among the six surfaces of the virtual rectangular parallelepiped 100.

  Therefore, as shown in FIG. 5, a part of the bus bar 315 is embedded and fixed in the rear side wall WB which is a specific wall. In other words, a part of the contact surface 31x of the main members 311 to 313 is included in the rear side wall WB which is a specific wall. Here, the specific wall is a wall that surrounds the internal space from the one surface side having the largest area among the six surfaces of the virtual rectangular parallelepiped 100, that is, from the rear surface side.

  As a result, the bus bar 315 is arranged on a relatively wide surface of the main members 311 to 313. That is, the bus bar 315 can reinforce a place that easily vibrates and a place that easily resonates. In the present embodiment, the right side wall WR and the left side wall WL are not the specific walls described above.

  Further, the right side wall WR, the left side wall WL, and the rear side wall WB are walls surrounding the air mix spaces 60PU, 60PL, 60DU, and 60DL. Accordingly, the bus bar 315 is embedded and fixed in the walls WR, WB, WL surrounding the air mix spaces 60PU, 60PL, 60DU, 60DL. Further, the contact surface 31x is included in the walls WR, WB, WL surrounding the air mix spaces 60PU, 60PL, 60DU, 60DL.

  The air mix spaces 60PU, 60PL, 60DU, and 60DL play a role of adjusting warm air and cold air that are heat-exchanged in the air-conditioned space to an appropriate temperature. For this reason, the air mix spaces 60PU, 60PL, 60DU, and 60DL are relatively wide spaces. Therefore, the walls WR, WB, WL surrounding the air mix spaces 60PU, 60PL, 60DU, 60DL tend to be wide and the rigidity is likely to be lowered. By reinforcing such walls WR, WB, WL with the bus bar 315, the reinforcing effect of the casing by the bus bar 315 can be enhanced.

  Further, in the air mix spaces 60PU, 60PL, 60DU, and 60DL, noise due to the blown air is relatively easily generated. Therefore, by arranging the bus bar 315 on the walls WR, WB, WL surrounding the air mix spaces 60PU, 60PL, 60DU, 60DL, the rigidity of the walls surrounding the air mix spaces 60PU, 60PL, 60DU, 60DL is increased, and the blown air Noise transmission can be suppressed.

  Of the actuators 41, 42, 43, 44 attached to the same left side wall WL, a pair of actuators 41, 43, a pair of actuators 41, 44, a pair of actuators 42, 43, a pair of actuators 42, 44, an actuator 43 , 44, the following can be said.

  If one of the pairs is a first actuator and the other is a second actuator, a part of the contact surface 31x is arranged in a specific path in the left side wall WL. Here, the specific path is the shortest path from the position closest to the first actuator to the position closest to the second actuator in the left side wall WL.

  Of the actuators 45, 46, 47, 48 attached to the same right side wall WR, a pair of actuators 45, 47, a pair of actuators 45, 48, a pair of actuators 46, 47, a pair of actuators 46, 48, an actuator 47 , 48 pairs, the following can be said.

  If one of the pairs is a first actuator and the other is a second actuator, a part of the contact surface 31x is arranged in a specific path on the right side wall WR. Here, the specific path is the shortest path from the position closest to the first actuator to the position closest to the second actuator on the right side wall WR.

  As a result, a part of the bus bar 315 is disposed so as to be surrounded by the first and second actuators. Therefore, since the portion surrounded by the first and second actuators tends to increase in vibration, efficient vibration suppression can be realized by doing in this way.

  Here, the operation of the vehicle air conditioner 1 will be described. At the time of cooling, the air conditioning control ECU operates the blower 22 and the compressor, thereby operating the refrigeration cycle. Therefore, the blown air cooled by the evaporator is cooled and blown into the vehicle interior. During heating, the air conditioning control ECU operates the blower 22 and does not operate the compressor. Therefore, the blown air warmed by the heater core 36 becomes warm air and is blown out into the vehicle interior.

  At the time of cooling or heating, the air conditioning control ECU, as necessary, drives the actuator units 41 to 48 via the bus bar 315 to drive each of the inside / outside air switching door, the air mix door group, and the mode door group. An electrical signal (that is, a control signal) is transmitted.

  Then, in each of the actuator units 41 to 48, the control unit receives the electric signal via the communication unit. And the said control part drives a motor based on the command content which the received electrical signal shows. Then, the output shaft of the motor rotates (that is, moves). Each door is driven by the rotation of the output shaft, and a desired position of each door is realized.

  At this time, when each motor is operated, vibration is generated in the motor. In this case, each motor is an excitation source. The vibration generated by each excitation source is transmitted to the entire air conditioning casing 31 through the contact portion of the air conditioning casing 31 with the actuator unit.

  At this time, as described above, a part of the bus bar 315 harder than the main members 311 to 313 is fixed to the wall WB having the largest area among the main members 311 to 314. Another part of the bus bar 315 is fixed to the wall WL whose area is not the largest, but is disposed at a position surrounded by the actuator units 41 to 44 that generate vibration. Another part of the bus bar 315 is fixed to the wall WR that is not the largest in area, but is disposed at a position surrounded by actuator units 45 to 48 that generate vibration. In other words, the bus bar 315 is arranged at a position where the bus bar 315 easily vibrates if the bus bar 315 is not provided. Therefore, the effect of suppressing vibration and resonance of the air conditioning casing 31 by the bus bar 315 is high. In addition, the effect of reducing transmitted sound can be obtained.

  Here, a case where only the bus bar 315 is removed from the air conditioning casing 31 by some method will be described. Such a situation does not occur in normal use, but may occur for reasons such as experimentally confirming the reinforcing effect of the bus bar 315.

  In such a state, vibration is generated in each excitation source as described above, and vibration transmitted from each excitation source to the main members 311 to 314 generates resonance in the main members 311 to 313. There is.

  In fact, the locations that were the contact surface 31x until the bus bar 315 was removed are, as described above, locations that resonate easily, portions that vibrate easily, and locations that resonate easily. In any of the right side wall WR, the left side wall WL, and the rear side wall WB, the vibration X is generated due to the vibration generated by the actuator units 41 to 48 in the portion that was the contact surface 31x until the bus bar 315 was removed. . The amplitude of the vibration X is larger than the amplitude of any of the excitation sources of the actuator units 41 to 48. This is true even when only one excitation source vibrates among the excitation sources (i.e., motors) of the actuator units 41 to 48, or even when a plurality of arbitrary excitation sources vibrate. As described above, the bus bar 315 is fixed at a location that easily vibrates or resonates, so that the effect of suppressing vibration and resonance of the air conditioning casing 31 by the bus bar 315 is enhanced.

  As described above, the air conditioning casing 31 of the present embodiment includes the main members 311, 312, 313, and 314, and the bus bar 315 that is fixed to the main members 311, 312, and 313 and transmits electric signals. Of the main members 311 to 313, the contact surface 31 x that contacts the bus bar 315 and its vicinity have a lower elastic modulus than the bus bar 315.

  In recent years, due to growing environmental awareness, electrical components using resin cases such as vehicle air conditioners have been made thinner to reduce the weight of the case. A method of providing a rib is known.

  On the other hand, however, the number of motors mounted on electrical components and the number of wirings connecting these motors are increasing as the functionality of automobiles has been improved.

  As the number of mounted motors increases, the number of excitation sources increases for the case, and the vibration rigidity decreases due to the thinning of the pine, making it easier to resonate, causing an increase in noise. As a countermeasure, a larger reinforcing rib is required, which leads to a complicated shape and a deterioration in electrical product productivity. Even with an increase in the number of wires, assembling becomes worse, such as the installation of wires, a hose for protecting the wires, and a taping for bundling. As a result, productivity deteriorates.

  The inventor has paid attention to the fact that when the actuator units 41 to 48 are attached to the air conditioning casing 31, a wire harness for passing an electrical signal sent to the actuator unit has been conventionally used. And as mentioned above, while fixing the bus bar 315 whose elastic modulus is higher than a part (namely, contact surface and its vicinity) of the main members 311 to 313 of the air-conditioning casing 31 to the main members 311 to 313, the bus bar An electrical signal is passed through 315.

  In this way, the bus bar 315 has a function of reinforcing the air conditioning casing 31 and a function of passing an electric signal to the actuator units 41 to 48. Therefore, since the number of wire harnesses can be reduced while reinforcing the air conditioning casing 31, it is possible to reduce the deterioration in productivity of the entire vehicle air conditioner 1 including the air conditioning casing 31.

Further, conventionally used wire harnesses for electric signals have been bundled with vinyl tape or the like, or have been protected with a dedicated protective member. On the other hand, in this embodiment, since such a vinyl tape etc. and a protection member become unnecessary, the number of parts of the vehicle air conditioner 1 is reduced.
In this proposal, it is not necessary because it is integrally formed with the case. Therefore, the number of parts is reduced, leading to cost reduction of the apparatus.

  Moreover, the wire harness for electric signals used conventionally was a soft body. As a result, the installation work of the wire harness has become unsuitable for mechanical work and has to rely on manual work. On the other hand, since the relatively hard bus bar 315 is used, automation work using a machine becomes easy and productivity is improved.

(Second Embodiment)
Next, a second embodiment will be described. In the present embodiment, any one or two or more of the actuator units 41 to 48 are replaced with the actuator unit 5 shown in FIGS. 8, 9, and 10 with respect to the vehicle air conditioner 1 of the first embodiment. It is. In the present embodiment, the bus bar is also provided in the actuator unit 5.

  Hereinafter, the configuration of the actuator unit 5 will be described in detail. The actuator unit 5 includes a casing 51, a control board 52, servo motors 53a and 53b, wire harnesses 541a, 541b, 541c, 541d, 543a, 543b, 543d, and 543d. In the present embodiment, not the actuator unit 5 but the servo motors 53a and 53b correspond to electrical components and actuators.

  The casing 51 is a rectangular shell-shaped casing that accommodates the control board 52 and the servo motors 53a and 53b in its internal space, and includes main members and bus bars 542a, 542b, 542c, and 542d. Like the casing 51, the main member has a rectangular parallelepiped shell shape. The material of the main member is the same as the main members 311 to 314 of the first embodiment. The main member has six walls 511, 512, 513, 514, 515 and 516.

  A wall 516 is fixed to the outer surface of the air conditioning casing 31 and faces the outer surface. A wall 516 and a wall 513 are arranged in parallel to each other. Further, the wall 511 and the wall 515 are arranged in parallel to each other, and the wall 512 and the wall 514 are arranged in parallel to each other. These walls 511, 512, 513, 514, 515, 516 surround the internal space of the casing 51.

  Further, a rib 51 a that is a part of the wall 513 is formed on the surface of the wall 513 on the inner space side. The rib 51 a is a member for reinforcing the casing 51. On the surface of the wall 513 on the inner space side, there are a portion where the ribs 51a are relatively sparse and a portion where the ribs are relatively densely arranged. Specifically, the portion facing the control board 52 and the portion facing the servo motors 53a and 53b on the inner space side surface of the wall 513 are portions where the ribs 51a are arranged relatively densely. Further, the portion of the surface of the wall 513 on the inner space side that faces the space between the control board 52 and the servomotors 53a and 53b is a portion where the ribs 51a are relatively sparse. The rib 51a extends on the surface of the wall 513 so as to intersect (more specifically, orthogonally) to the plate surface of the wall 513.

  The bus bars 542a, 542b, 542c, and 542d are all embedded and fixed in the wall 513, and are fixed to the wall 513. The bus bars 542a, 542b, 542c, and 542d pass electrical signals transmitted and received between the control board 52 and the servo motors 53a and 53b, and also function as reinforcing members for the casing 51. The configuration and arrangement of the bus bars 542a, 542b, 542c, and 542d will be described later.

  The control board 52 is a board on which the communication unit and the control unit described in the first embodiment are mounted. One end of each of the wire harnesses 541a, 541b, 541c, and 541d is connected to the control unit of the control board 52. The other ends of the wire harnesses 541a, 541b, 541c, and 541d are connected to one ends of the bus bars 542a, 542b, 542c, and 542d. The other ends of the bus bars 542a, 542b, 542c, and 542d are connected to one ends of the wire harnesses 543a, 543b, 543c, and 543d. The other ends of the wire harnesses 543a and 543b are connected to the servo motor 53a. The other ends of the wire harnesses 543c and 543d are connected to the servo motor 53b.

  The signal line constituted by the wire harness 541a, the bus bar 542a, and the wire harness 543a may be a control signal line that outputs a control signal (for example, a pulse signal) from the control board 52 to the servo motor 53a. The signal line constituted by the wire harness 541b, the bus bar 542b, and the wire harness 543b may be a feedback signal line that outputs operation information (for example, a rotation angle) from the servo motor 53a to the control board 52.

  In this case, the servo motor 53a operates based on a control signal received from the control board 52 via the control signal line, and outputs operation information corresponding to the operation to the control board 52 from the feedback line. The servo motor 53a drives the door in the same manner as the servo motor of the first embodiment.

  The signal line configured by the wire harness 541c, the bus bar 542c, and the wire harness 543c may be a signal line that outputs a control signal (for example, a pulse signal) from the control board 52 to the servo motor 53b. The signal line constituted by the wire harness 541d, the bus bar 542d, and the wire harness 543d may be a signal line that outputs operation information (for example, a rotation angle) from the servo motor 53b to the control board 52.

  In this case, the servo motor 53b operates based on a control signal received from the control board 52 via the control signal line, and outputs operation information corresponding to the operation to the control board 52 from the feedback line. This servo motor 53b drives the door in the same manner as the servo motor of the first embodiment.

  Here, the configuration and arrangement of the bus bars 542a, 542b, 542c, and 542d will be described in detail. First, the material of the bus bars 542a, 542b, 542c, 542d will be described. The bus bars 542a, 542b, 542c, and 542d are conductive members having higher elastic modulus and Young's modulus than any part of the walls 511 to 516 that are main members.

  Therefore, naturally, the contact surface 51x of the wall 513 with the bus bars 542a, 542b, 542c, and 542d and a part of the vicinity thereof have lower elastic modulus and Young's modulus than the bus bars 542a, 542b, 542c, and 542d. Therefore, the casing 51 can be reinforced by the bus bars 542a, 542b, 542c, and 542d. In addition, the contact surface 51x is all surfaces which contact a bus bar among main members.

  Further, in a cross section including both of the main member and the bus bars 542a, 542b, 542c, 542d (for example, the cross section of FIG. 10), the bending rigidity of the bus bars 542a, 542b, 542c, 542d with respect to any axis parallel to the cross section. Is higher than the bending rigidity of the main member with respect to the shaft. By doing in this way, the reinforcement effect of the air-conditioning casing 31 by bus-bar 542a, 542b, 542c, 542d can be heightened more.

  Specifically, the bus bars 542a, 542b, 542c, and 542d may be generated by punching from a punching material of a brass plate. The bus bar 315 is fixed to the wall 513 by insert molding. That is, the entire bus bars 542a, 542b, 542c, and 542d are integrally formed with the wall 513. As a result, the bus bars 542a, 542b, 542c, and 542d are integrated with the main member.

  Next, the arrangement of the bus bars 542a, 542b, 542c, and 542d will be described. The bus bars 542a, 542b, 542c, 542d are embedded in the wall 513. With this configuration, the contact area between the bus bars 542a, 542b, 542c, and 542d and the wall 513 increases, so that the reinforcing effect of the casing 51 by the bus bars 542a, 542b, 542c, and 542d can be enhanced.

  One ends of the bus bars 542a, 542b, 542c, and 542d on the control board 52 side are exposed from the wall 513 and are connected to the wire harnesses 541a, 541b, 541c, and 541d, respectively. One ends of the bus bars 542a, 542b, 542c, and 542d on the servo motors 53a and 53b side are exposed from the wall 513 and are connected to the wire harnesses 543a, 543b, 543c, and 543d, respectively. The power supply to the servo motors 53a and 53b is performed via a wire harness.

  In addition, the bus bars 542a, 542b, 542c, and 542d are embedded in the walls of portions where the ribs 51a are relatively sparse. That is, since the strength of the portion where the bus bars 542a, 542b, 542c, and 542d are embedded increases, the arrangement of the rib 51a can be the ancestor. Therefore, the shape of the wall 511 can be simplified by the bus bars 542a, 542b, 542c, and 542d.

  The walls 511 to 516 of the casing 51 will be further described. First, a virtual cuboid is defined. The virtual rectangular parallelepiped is the smallest virtual rectangular parallelepiped that can accommodate the entire walls 511 to 516. In the present embodiment, the six surfaces of such a virtual rectangular parallelepiped coincide with the outer surfaces of the walls 511 to 516. Therefore, each of the walls 511 to 516 is closest to the surface of the six surfaces of the virtual rectangular parallelepiped that is the same. In addition, each of the walls 511 to 516 surrounds the internal space of the casing 51 from the surface side with which the six surfaces of the virtual rectangular parallelepiped coincide. Moreover, in this embodiment, the surface which corresponds to the walls 513 and 516 among the six surfaces is one surface having the largest area among the six surfaces of the virtual rectangular parallelepiped.

  Therefore, the wall 511 in which the entire bus bars 542a, 542b, 542c, and 542d are embedded is a specific wall. In other words, the entire contact surface 51x of the wall 513 is included in the wall 513 which is a specific wall. Here, the specific wall is a wall that surrounds the internal space from the one surface side having the largest area among the six surfaces of the virtual rectangular parallelepiped.

  As a result, the bus bars 542a, 542b, 542c, and 542d are arranged on a relatively wide surface of the wall 511. That is, a place that easily vibrates or a place that easily resonates can be reinforced by the bus bars 542a, 542b, 542c, and 542d. In the present embodiment, the walls 511, 512, 514, and 515 are not specific walls.

  Here, the operation of the vehicle air conditioner 1 will be described. During cooling or heating, the air conditioning control ECU electrically connects the actuator unit 5 via the bus bar 315 to drive each of the inside / outside air switching door, the air mix door group, and the mode door group as necessary. Send a signal (ie a control signal).

  Then, in the actuator unit 5, the control unit receives the electrical signal via the communication unit. And the said control part outputs a control signal to the servomotor 53a via the control signal wire | line 541a, 542a, 543a based on the command content which the received electric signal shows. Then, the output shaft of the motor rotates (that is, moves). Further, the servo motor 53a outputs operation information such as the rotation position of the own machine to the control board 52 via the feedback signal lines 541b, 542b, and 543b. The control board 52 outputs a control signal to the servo motor 53a via the control signal lines 541b, 542b, and 543b based on the operation information. The control board 52 and the servo motor 53b perform the same operation via the control signal lines 541c, 542c and 543c and the feedback signal lines 541d, 542d and 543d.

  At this time, the servo motors 53a and 53b rotate to generate vibrations in the servo motors 53a and 53b. In this case, the output shafts and brackets of the servomotors 53a and 53b are excitation sources. The vibration generated by each excitation source is transmitted to the entire casing 51 through a contact portion of the casing 51 with the servo motors 53a and 53b.

  At this time, as described above, the bus bars 542a, 542b, 542c, and 542d that are harder than the wall 513 are fixed to the wall 513 having the largest area among the walls 511 to 516. In other words, the bus bars 542a, 542b, 542c, and 542d are arranged at locations that easily vibrate without the bus bars 542a, 542b, 542c, and 542d. Therefore, the effect of suppressing vibration and resonance of the casing 51 by the bus bars 542a, 542b, 542c, and 542d is high. Further, the effect of reducing the transmission of the operating sound of the servo motors 53a and 53b can be obtained.

  Here, a case where only the bus bars 542a, 542b, 542c, and 542d are removed from the casing 51 by some method will be described. Such a situation does not occur in normal use, but may occur for the purpose of experimentally confirming the reinforcing effect by the bus bars 542a, 542b, 542c, and 542d.

  In such a state, vibration is generated in each excitation source as described above, and vibration transmitted from each excitation source to the walls 511 to 516 may generate resonance in the walls 511 to 516. .

  In fact, as described above, the location that was the contact surface 51x until the bus bars 542a, 542b, 542c, and 542d are removed is a location that easily resonates, a location that easily vibrates, and a location that easily resonates. In the wall 513, the vibration X occurs due to the vibration generated by the servo motors 53a and 53b in the portion that was the contact surface 51x until the bus bars 542a, 542b, 542c, and 542d were removed. The amplitude of the vibration X is larger than the amplitude of any of the excitation sources of the servo motors 53a and 53b. This is true whether only one of the servo motors 53a and 53b is operating or both are operating. In this way, by fixing the bus bars 542a, 542b, 542c, and 542d to locations that easily vibrate and resonate, the effects of suppressing vibration and resonance suppression of the casing 51 by the bus bars 542a, 542b, 542c, and 542d are high. Become.

  As described above, the casing 51 of the present embodiment includes the walls 511 to 516 and the bus bars 542a, 542b, 542c, and 542d that are fixed to the walls 511 to 516 and that allow electric signals to pass therethrough. Of the wall 513, the contact surface 51x that contacts the bus bars 542a, 542b, 542c, and 542d and its vicinity have a lower elastic modulus than the bus bars 542a, 542b, 542c, and 542d.

  As a result, the bus bars 542a, 542b, 542c, and 542d have a function of reinforcing the casing 51 and a function of passing an electric signal to the servo motors 53a and 53b. Therefore, since the number of wire harnesses can be reduced while reinforcing the casing 51, the deterioration of the productivity of the entire actuator unit 5 including the casing 51 and the entire vehicle air conditioner 1 can be reduced. In addition, the same effects as those of the first embodiment can be obtained.

  Further, when a plurality of servo motors 53a and 53b are built in the casing 51, the positional relationship depends on the layout of each door of the vehicle air conditioner 1 and the axial position thereof, so the servo motors 53a and 53b motors. The distance between them may be longer. At that time, since a relatively wide space is formed between the servo motor 53a and the servo motor 53b, a portion where the vibration of the motor more easily resonates occurs. In the present embodiment, this is the location of the contact surface 51x. By fixing the bus bars 542a, 542b, 542c, and 542d at such locations, more effective vibration suppression and resonance suppression are realized.

The present invention also allows the following modifications to the above embodiments. In addition, the following modifications can select application and non-application to the said embodiment each independently. In other words, any combination of the following modifications can be applied to the above-described embodiment.

(Modification 1)
In each of the above embodiments, the bus bar 315 and the bus bars 542a, 542b, 542c, and 542d have a higher elastic modulus and Young's modulus than any part of the main member, but this is not necessarily the case. It is only necessary that the contact surfaces 31x and 51x that contact the bus bar 315 and the bus bars 542a, 542b, 542c, and 542d and the vicinity thereof have a lower elastic modulus than the bus bar.

(Modification 2)
The bus bar 315 and the bus bars 542a, 542b, 542c, and 542d in each of the above embodiments are connected to the motor, but may be attached to the sensor instead of the motor. In this case, the sensor corresponds to an electrical component. Even if the actuator is not attached to the casing 31, vibration is generated by the blown air in the air-conditioned space, so that vibration suppression is necessary.

(Modification 3)
In each of the above embodiments, a bus bar (that is, a rod-shaped member) is described as an example of a conductive member. However, the conductive member may be a member other than the buzz bar.

(Modification 4)
In the above embodiments, the bus bar 315 and the bus bars 542a, 542b, 542c, and 542d are embedded in the main member. However, the fixed form with respect to the main member of a bus bar is not restricted to such a thing. For example, only a part of the side surface of the bus bar may be fixed to the main member, and the other side surface may be exposed to the outside of the casings 31 and 51. If it does in this way, the structure which hold | maintains a bus-bar inside a metal mold | die at the time of insert molding can be comprised. In addition, electrical contacts can be configured at any location (summary)
According to the first aspect shown in part or all of the above embodiments, the electrical component is attached and the casing surrounding the internal space is fixed to the main member and connected to the electrical component. And a conductive member for passing an electrical signal. Among the main members, the contact surface that contacts the conductive member and the vicinity thereof have a lower elastic modulus than the conductive member.

  According to the second aspect, in the cross section including both the main member and the conductive member, the bending rigidity of the conductive member with respect to any axis parallel to the cross section is higher than the bending rigidity of the main member with respect to the axis. . By doing in this way, the reinforcement effect of a casing can be heightened more.

  According to the third aspect, the electrical component is an actuator, and the vibration generated by the actuator is transmitted from the excitation source of the actuator to the main member, and the conductive member is removed in a state where the conductive member is removed. When vibration X is generated due to the vibration generated by the actuator until the portion that has been the contact surface is removed, the amplitude of vibration X is larger than the amplitude of vibration of the excitation source.

  Thus, if there is no conductive member, efficient vibration suppression can be realized by fixing the conductive member at a location where vibration is amplified more than the excitation source.

  According to the fourth aspect, at least a part of the contact surface of the main member is included in the specific wall, and the specific wall is the internal space from the one surface side having the largest area among the six surfaces of the virtual rectangular parallelepiped. It is a wall that surrounds. The wall is closest to the one of the six surfaces, and the virtual rectangular parallelepiped is the smallest virtual rectangular parallelepiped that can accommodate the entire main member. As a result, the conductive member is arranged on a relatively wide surface of the main member. That is, it is possible to reinforce the place that is more likely to vibrate with the conductive member.

  According to the fifth aspect, the electrical component is the first actuator, and the second actuator is attached to the casing, and one of the contact surfaces is provided in a specific path in the wall constituting the main member. The specific path is the shortest path on the wall from the position closest to the first actuator to the position closest to the second actuator.

  With this configuration, a part of the conductive member is disposed so as to be surrounded by the first and second actuators. Therefore, the portion surrounded by the first and second actuators tends to increase the vibration if there is no bus bar. Thus, efficient vibration suppression can be realized.

  Moreover, according to the 6th viewpoint, a casing is an air-conditioning casing surrounding the air-conditioning space where the ventilation air which blows off into a vehicle interior is heated or cooled. In this way, the air conditioning casing can be reinforced and the deterioration of the productivity of the vehicle air conditioner including the air conditioning casing can be reduced.

  Moreover, according to the 7th viewpoint, the heating part which heats the air which passes is arrange | positioned in an air-conditioning space, and air-conditioning space is the air which passed the heating part among the ventilation air, and the air which did not pass the heating part. Has an air mix space in which are mixed. The contact surface of the main member is included in a wall surrounding the air mix space.

  The air mix space plays a role of adjusting the temperature to an appropriate temperature by mixing warm air and cold air exchanged in the air-conditioned space. For this reason, the air mix space becomes a relatively large space. Therefore, the rigidity of the wall surrounding the air mix space is also likely to decrease. By reinforcing such a wall with a conductive member, the reinforcing effect of the casing by the conductive member can be enhanced.

  According to the eighth aspect, the electrical component is an actuator that moves a movable member disposed in an air-conditioning casing that surrounds an air-conditioned space in which blown air blown into the passenger compartment is heated or cooled. And a casing is a casing which accommodates an actuator. In this way, the actuator casing can be reinforced and the deterioration of the productivity of the vehicle air conditioner including the casing can be reduced.

  According to the ninth aspect, the conductive member is embedded in the main member. Since the contact area of an electroconductive member and a main member increases by doing in this way, the reinforcement effect of the casing by an electroconductive member can be heightened.

  According to the tenth aspect, the electrical component receives the electrical signal and moves according to the electrical signal. In this way, the conductive member has a function of reinforcing the casing and a function of passing an electric signal to the actuator.
