Description

  The present invention relates to a switch unit that is built in, for example, an automatic transmission of a vehicle.

Hereinafter, a switch used for detecting that the shift lever of the vehicle has been switched will be described as an example.
Conventionally, this type of switch requires a switch having three detection functions corresponding to the switching operation in the three directions when the shift lever is switched. For example, in the first detection, it is a shift mode switch that detects that the speed mode of the automatic vehicle has been switched to the manual shift mode, and in the second detection, it has been detected that the speed has been switched to the upshift (+) speed. The third detection is a shift-down detection switch that detects that the speed has been switched to a shift-down (−) speed. In order to obtain these three detection functions, one having three independent switches individually is known.

However, in this case, since three independent switches are individually arranged at the detection position of the shift lever , the number of parts increases, the assemblability of the switch deteriorates, and the size and cost are high. Had a problem.

  In addition, there is one in which three switch functions are integrated so that different external forces can be detected in three directions. This is because the fixed terminals for detecting upshifts and downshifts are arranged in a plane in the horizontal direction, and the fixed terminals for detecting the speed change mode are arranged in the vertical direction. By making the body correspond, the three switch functions are integrated (for example, see Patent Document 1).

However, in order to provide different detection functions in three directions, detection members corresponding to the horizontal direction and the vertical direction are incorporated, and even if they can be integrated, there is a limit to downsizing. Specifically, there is a limit to downsizing (thinning) because a rotation space for changing the direction of moving the movable contact from the vertical direction to the horizontal direction is required. In particular, when assembling, it is difficult to assemble because assembly from different directions is required. Further, when assembling with an automatic machine, it has a complicated configuration due to the restriction of incorporating from a plurality of assembling directions, and efficient automatic assembling cannot be realized.

Then, as shown in FIG. 2B, when the driver operates the shift lever 13 in the left-right direction (in the direction of the arrow in the figure) to switch from the automatic transmission mode operation area to the manual transmission mode operation area, The child 14 approaches the switch unit U. At this time, the second operation lever 17 for mode switching is pushed by the operator 14 and the second switch 12 is turned on, and the shift lever 13 is switched from the automatic transmission mode to the manual transmission mode. Detects an operation.

  When the manual shift mode is switched, the operation protrusion 15 is interposed in the U-shaped space formed in the U-shape of the first operation lever 16, and in this state, the shift lever 13 moves the first operation lever 16 to one side (down). The other (up) shift switching direction can be operated. When the shift lever 13 is operated in one of the front and rear directions (in the direction of the arrow in the figure) or the other in the operable state, the shift is switched to the shift corresponding to the direction in which the first operation lever 16 is operated. Is detected.

  As shown in FIG. 3, the switch unit U has a structure in which two sets of switches 11 and 12 including a first switch 11 and a second switch 12 supported by a base 18 and a cover 19 are integrated. ing. In this case, the first to fifth fixed terminals T1 to T5 are arranged on the same plane on the upper surface of the base 18 to form a temporarily assembled housing portion 20, and one side of the housing portion 20 on the same plane and the other. The first switch 11 and the second switch 12 are mounted and configured on the side.

  The base 18 is formed of a thermoplastic resin excellent in electrical insulation, and the first to fifth fixed terminals T1 to T5 are spaced apart from each other on the same plane on a box-shaped inner bottom surface whose upper surface is opened. These fixed terminals T1 to T5 are provided by pressing a conductive metal plate into a predetermined pattern shape. And the welding resin material 21a is integrally fixed to the defined position of the base 18 by the heat caulking etc. to the fixing hole 21 for welding penetrated by each fixing terminal T1-T5. In addition, one end of each of the fixed terminals T1 to T5 is formed as an elongated connector terminal 21b, the connector terminals 21b are aligned for wiring connection, and side openings (connectors) opened on one side in the longitudinal direction of the base 18 It is arranged facing the outside from the cable insertion port 22. Then, an external connector cable (not shown) is wired and connected to the base 18 from the same plane direction. The wiring direction is not limited to the plane direction of the base 18, and the direction of the connector terminal 21 b is changed to the vertical direction bent from the plane direction of the base 18 to the upper surface side or the lower surface side, so that the vertical direction of the switch unit U It is also possible to provide a wiring connection.

  Further, a shaft hole 23 that pivotally supports the inner end side of the first operation lever 16 in the vertical direction is provided at a central portion on one side of the base 18. Further, a side opening 24 is provided on one side surface of the base 18 corresponding to the shaft hole 23 so that the outer end side of the first operation lever 16 protrudes outward. Further, a locking claw 25 for attaching the cover is provided on the outer periphery of the side surface of the base 18, and a locking hole 55 of the cover 19 described later is locked to each locking claw 25, thereby The cover 19 is integrally connected to cover the opening.

FIG. 5 is a plan view showing the arrangement of the fixed terminals, and FIG. 6 is a cutaway perspective view of the main part showing the internal structure of each switch. First, the configuration of the first switch 11 will be described.
The first switch 11 includes first to third fixed terminals T1 to T3, a first operating lever 16, a first return spring 26, a rotary sliding movable terminal 27, a base 18 that supports them, and a cover. 19.

  The first fixed terminal T <b> 1 is horizontally disposed on the upper surface of the base 18 as a common terminal in the first switch 11. The second fixed terminal T2 is disposed on one side with the first fixed terminal T1 as a central portion as a fixed terminal for shift-down switching. The third fixed terminal T3 is arranged on the other side as the fixed terminal for upshift switching with the first fixed terminal T1 as the central portion. Further, as shown in FIG. 5 (A), the inner end portion of the first fixed terminal to the third fixed terminals T1 to T3 is disposed in the side opening 22 for wiring connection. It is provided as an annular terminal group 28 that is horizontally and annularly arranged around the shaft hole 23. Then, as shown in FIG. 5B, a disk-shaped rotary sliding movable terminal 27 is mounted on the upper surface of the annular terminal group 28.

  The first operating lever 16 has a circular portion on the inner end side in the horizontal direction and a U-shaped portion on the outer end side. The circular portion on the inner end side is opposed to the upper surface of the base 18 in a plane, and a lower support shaft 29 protruding from the center of the lower surface of the circular portion is supported by the shaft hole 23 of the base 18. Further, the upper support shaft 30 protruding from the center of the upper surface of the circular portion is supported by a shaft hole 31 of the cover 19 described later (see FIG. 6). As a result, the first operating lever 16 is pivotally supported about the support shafts 29 and 30 so as to freely rotate. Further, an annular spring accommodating portion 32 is provided on the upper surface of the circular portion, and the coiled first return spring 26 is accommodated therein.

  As described above with reference to FIG. 2, the U-shaped portion on the outer end side has the open surface of the U-shaped portion facing outward, and the operation projection 15 of the operation element 14 can be moved toward and away from the U-shaped space. Oppositely, when the operation protrusion 15 approaches and is interposed in the U-shaped space, the operation protrusion 15 is in a state where the first operation lever 16 can be operated. Then, the first operation lever 16 rotates following the movement of the operation protrusion 15 being operated in one or the other in the short direction of the base. In this case, one lever piece of the U-shaped portion serves as a shift-down operation lever 33 and the other lever piece serves as a shift-up operation lever 34.

  The first return spring 26 is a coil spring sized to be accommodated in the annular space of the spring accommodating portion 32, and both end portions 26a and 26b of the coil spring protrude outwardly in a letter C shape. 26a and 26b are engaged with and attached to a spring engaging portion 35 formed on the upper surface of the base 18 through an opening portion 32a opened on the annular side surface of the spring accommodating portion 32. As a result, the first return spring 26 has the spring engagement portions 35 on both the left and right sides as bias reference positions, and the annular portion of the coil spring that is in contact with the inner peripheral surface of the spring storage portion 32 is integrated with the operation lever 16. The first operating lever 16 is held in the neutral position by receiving the urging force of the first return spring 26. Therefore, the first operating lever 16 is rotated to one or the other against the biasing force of the first return spring 26, and when the operating force on the first operating lever 16 is released, the first operating lever 16 Is rotated from the position rotated by the urging force of the first return spring 26 to the neutral position and returned. Then, a rotary sliding movable terminal 27 described later is fixed to the lower surface of the circular portion of the first operation lever 16.

  The above-described rotary sliding movable terminal 27 is fixed to the lower surface of the circular portion of the first operating lever 16 and has a circular shape corresponding to the upper surface of the annular terminal group 28, and is in contact with the annular terminal group 28. The plate spring-like three contacts 27a, 27b, 27c, which are made of a conductive metal plate that conducts and is divided into three in the circumferential direction and bent and deformed, are annularly arranged. In addition, a fixing hole 36 is formed so as to penetrate the lower surface of the circular portion of the first operating lever 16 for fixing.

  The contacts 27a, 27b, and 27c are a common contact 27a that is always in contact with the first fixed terminal T1, and, as shown in FIG. 7C, the first operating lever 16 rotates from the neutral position to the shift-down side. When the first operation lever 16 is rotated from the neutral position to the shift-up side as shown in FIG. 8C, the third fixed terminal It consists of a shift-up contact 27c that comes into contact with T3, and rotates together with the rotation operation of the first operation lever 16.

  In this case, the rotary sliding movable terminal 27 that rotates up and down and the annular terminal group 28 are arranged in a circular shape that can be gathered locally on the inside of the base 18, and the compact that switches the contact point in the rotational direction. It becomes a contact structure in various arrangement areas. For this reason, size reduction of a switch structure can be achieved.

Next, the configuration of the second switch 12 will be described. 9 is an exploded perspective view of the second switch, FIG. 10 is a perspective view of the second switch viewed from the bottom side, and FIG. 11 is an exploded perspective view of the second switch viewed from the bottom side.
The second switch 12 includes a fourth fixed terminal T4, a fifth fixed terminal T5, a second operation lever 17, a slide-type movable terminal 39, a base 18 that supports them, and a cover 19.

  The fourth fixed terminal T4 is disposed horizontally on the upper surface of the base 18 as a terminal that is always in contact with the second switch 12. The fifth fixed terminal T5 has an L shape so as to surround the inner end side of the fourth fixed terminal T4 and is horizontally disposed on the upper surface of the base 18 for changing the transmission mode.

  The second operating lever 17 is provided in the shape of a rectangular plate, and lever shafts 40 project from both side surfaces on the base end side of the rectangular plate. The lever shaft 40 is pivotally supported by a cover 19 which will be described later, and the second operation lever 17 is incorporated in the cover 19. Further, a contact corresponding portion 41 protruding in a semicircular shape is provided on the free end side of the rectangular plate shape. This contact corresponding portion 41 faces the above-described operation element 14 and rotates upon receiving an operation force from the operation element 14.

  Further, shaft support arms 42 are provided on both sides of the lower surface of the base end side of the rectangular plate shape, and a slider 38 (described later) is supported by a swing support hole 43 formed at the lower end of the shaft support arm 42. Is done. A concave spring mounting portion 44 for inserting and mounting a second return spring 37 (described later) from one side is formed on the lower surface side of the rectangular plate shape.

  The above-described second return spring 37 extends the spring wire from both ends wound in a coil shape in the opposite direction of one and the other, and the extended one extended portion 37a is the spring mounting portion. 44, and the other short extension 37b is attached to the cover 19 which will be described later. The urging direction of the second return spring 37 is set so that the contact corresponding portion 41 on the free end side with the lever shaft 40 as the pivot is the perspective corresponding direction with the operating element 14 as shown in FIG. doing. The second operating lever 17 is supported by the biasing action of the second return spring 37 in a state in which the second operating lever 17 protrudes from the outer surface of the cover 19 to be inclined by about 45 degrees outward from the outer surface of the cover 19. At this time, the urging direction of the second operation lever 17 detects an orthogonal direction different from the external force detection direction (front-rear direction shown in FIG. 2B) detected by the first switch 11.

  The slider 38 is provided in the shape of a rectangular parallelepiped, and is provided with projecting spindles 45 for sliding on both sides in the lateral direction. The slide support shafts 45 on both sides are pivotally supported by the swing support hole 43 of the second operation lever 17, and the slider 38 is attached in a state of being suspended from the second operation lever 17. The slider 38 that is pivotally supported in this suspended state has the swing support hole 43 as a swing support point, and the support shaft 45 of the slider 38 is allowed to move in the vertical direction within the swing support hole 43. 2. In conjunction with the movement of the operating lever 17 rotating in the vertical direction, the slider 38 can be slid by changing its direction into a movement of sliding in the horizontal direction.

  In addition, a slide guide rail groove 46a is provided in the longitudinal direction of the center of the slider 38, and the rail groove 46a is slidably supported by a guide rail 59 of the cover 19 described later. Further, a rectangular stepped opening 46 is provided in the center of the slider 38 so as to penetrate in the vertical direction. Then, locking protrusions 48 of a slide-type movable terminal 39, which will be described later, are locked to recessed step portions 47 that are further concaved on both side surfaces of the stepped opening 46, and the slide type is formed on the lower surface side of the slider 38. A movable terminal 39 is provided to be connected.

  The above-described slide type movable terminal 39 is formed of a metal plate having conductivity and leaf spring property, and is engaged with a fitting piece 49 fitted into the stepped opening 46 at the center and a recessed step 47. Locking protrusions 48 for stopping are formed on both sides. Furthermore, one side in the sliding direction is elongated with a spring property, and the contact 50 that is always in contact with the fourth fixed terminal T4 and the other in the sliding direction are elongated with a spring property, and the second When the operating lever 17 receives an external force (the operating force of the operating element 14) and rotates to the tilted position, the operating lever 17 has a movable contact 51 that contacts the fifth fixed terminal T5.

  The cover 19 is made of an insulating thermoplastic resin material that covers the upper surface of the base 18 and is attached integrally. The cover 19 has a shaft hole 31 for supporting the upper support shaft 30 of the first operation lever 16 on the lower surface of the first operation lever 16, and lever shafts 40 projecting on both sides of the second operation lever 17 on the lower surface of the other side. It has a pair of left and right semicircular recesses 52 that are pivotally supported. A lever attachment port 53 is opened between the recesses 52 of the cover 19. Further, in the vicinity of the lever mounting opening 53, there are provided a spring locking portion 56 corresponding to the short extension portion 37b and a guide rail 59 for engaging and guiding the guide groove 46a of the slider 38. Yes. Then, the second operating lever 17 is inserted into the lever mounting port 53 so as to be pushed in from the lower surface side of the cover 19, and the lever shaft 40 of the second operating lever 17 is fitted into the recess 52 and attached. As a result, the second operating lever 17 is held by the cover 19 with the lever shaft 40 pivotally supported by the recess 52 as a pivot.

  Further, the cover 19 is provided with an upright elongated temporary fixing holding piece 54 erected toward the downward opening surface of the recess 52. The temporary holding piece 54 moves to open and close by temporarily elastically displacing the open surface of the recess 52 in conjunction with the fitting operation of the lever shaft 40 that is pushed into the recess 52 and fitted. Therefore, after the lever shaft 40 is pushed into and fitted into the recess 52, the lever shaft 40 can be retained with the recess 52 closed by the free end of the temporary fixing holding piece 54. Can be temporarily fixed to the cover 19. Further, since the second return spring 37 and the slider 38 can be assembled in advance to the second operation lever 17, the second switch 12 can be provisionally assembled. For this reason, the handling of the parts which constitute the 2nd switch 12 becomes easy, and the incorporation to the housing part 20 becomes easy.

  Further, around the cover 19, locking holes 55 are formed at positions corresponding to the cover mounting locking claws 25 protruding around the base 18. By attaching the cover 19 so as to cover the cover 19, the lock hole 55 is locked to the lock claw 25, so that the base 18 and the cover 19 can be mounted integrally.

  Further, the lever shaft 40 of the second operating lever 17 is provided with the lever shaft 40 so that the lever shaft 40 can be smoothly fitted into the recess 52 while the temporary holding piece 54 is elastically displaced. A fitting guide surface 40a is formed by chamfering the upper half, which is the fitting direction of the end face, in an inclined manner on the end face. A terminal guide portion 57 (see FIGS. 4 and 5) for partitioning and guiding the fixed terminals T1 to T5 is formed on the upper surface of the base 18, and the base 18 is raised with respect to the open surface of the recess 52. The piece 58 is raised. When the second switch 12 is assembled together with the cover 19 on the base 18, the upright piece 58 stabilizes the lever shaft 40 by reliably supporting the upright piece 58 from the lower surface side with the upright piece 58. So that it can be pivotally supported.

FIG. 12 is an enlarged perspective view of a main part showing a swinging support state of the slider 38, and FIG. 13 is an explanatory view showing a contact switching state of the second switch 12.
The swing support hole 43 that pivotally supports the support shaft 45 of the slider 38 is a long hole that is opened slightly longer in the downward radial direction around the lever shaft 40 of the second operation lever 17. That is, the hole length L2 of the swing support hole 43 is longer than the diameter length L1 of the support shaft 45. As a result, as described above, the support shaft 45 follows the movement of the second operation lever 17 to rotate, the support shaft 45 moves up and down in the swing support hole 43, and the slider 38 moves in the horizontal direction. The slider 38 slides stably on the fourth fixed terminal T4 and the fifth fixed terminal T5.

  Further, a fitting opening 43 a for fitting the support shaft 45 is cut out at the lower end of the swing support hole 43. Further, the size of the fitting opening 43a is provided in a retaining dimension L3 that is slightly smaller than the diameter length L1 of the support shaft 45, and is narrowed down so that the support shaft 45 can be fitted from the fitting opening 43a. Has elasticity. Thereby, the slider 38 can be fitted and attached to the second operation lever 17. Further, after the fitting, the size of the fitting opening 43a is smaller than the diameter length L1 of the support shaft 45, so that it is securely removed and does not come off. For this reason, the slider 38 can be easily temporarily assembled to the second operation lever 17.

  Next, when assembling the switch unit U, as shown in FIG. 3, as shown in FIG. 4, the housing part 20, the first switch 11, 2 can be temporarily assembled with the cover 19 incorporating the switch 12. After that, efficient assembly is possible by assembling the main assembly.

  First, when the housing part 20 is temporarily assembled, the first to fifth fixed terminals T1 to T5 are arranged at predetermined positions on the upper surface of the base 18 by an automatic machine, and resin welding (thermal caulking) is performed. Thus, the housing part 20 is constructed by welding and fixing all the fixed terminals T1 to T5 on the base 18. In this case, the fixed terminals T1 to T5 can be mounted on the base 18 in the same direction on the same plane of the base 18 in the same direction.

  When the first switch 11 is temporarily assembled, the rotary sliding movable terminal 27 having a smaller diameter disk is disposed on the lower surface of the circular portion of the first operating lever 16, and the first operation is performed by resin welding with an automatic machine. The lever 16 and the rotary sliding movable terminal 27 are integrated, and the first switch 11 (excluding the fixed terminal) 11 is attached by fitting and attaching the first return spring 26 to the spring accommodating portion 32 of the first operation lever 16. Can be temporarily assembled.

  Similarly, when temporarily assembling the second switch 12 integrated with the cover 19, the slide-type movable terminal 39 is inserted into the stepped opening 46 of the slider 38 from below, and the locking protrusion 48 is inserted into the recessed step 47. The slide type movable terminal 39 is incorporated in the slider 38 by being locked. The slider 38 is attached to the second operation lever 17 by fitting the support shaft 45 of the slider 38 incorporating the slide type movable terminal 39 into the swing support hole 43 opened below the second operation lever 17. It is done.

  Thereafter, with the second return spring 37 inserted and attached to the spring attachment portion 44 of the second operation lever 17, the second operation lever 17 is passed from the lower surface side of the cover 19 to the lever attachment port 53, and the lever shafts on both sides are inserted. The second switch (excluding the fixed terminal) 12 and the cover 19 are integrated with each other by fitting the 40 into the recesses 52 of the cover 19 and engaging the short extending portion 37 b with the spring engaging portion 56 of the cover 19. Can be temporarily assembled.

  After the temporary assembly is completed, the lower support shaft 29 that protrudes from the lower surface of the first operating lever 16 is mounted on the base 18 so that the first switch 11 that is temporarily assembled is mounted on the upper surface opening portion of the housing portion 20 from above. The shaft hole 23 is inserted. At this time, both end portions 26 a and 26 b of the first return spring 26 of the first switch 11 are respectively locked to the spring locking portions 35 on the base 18. Accordingly, the first operating lever 16 is assembled in a state of being biased and supported at the neutral position.

  Thereafter, a cover 19 incorporating the second switch 12 may be attached. When the cover 19 is attached, the upper support shaft 30 protruding from the upper surface of the first operation lever 16 is covered with the shaft hole 31 of the cover 19 so as to be supported from above. At this time, the locking holes 55 provided around the cover 19 are locked by the locking claws 25 protruding around the base 18, and the first switch 11 and the second switch 12 are assembled on the housing portion 20. The cover 19 is integrally connected.

  At the time of this assembly, it can be easily assembled because it is only necessary to assemble from the same direction so as to be mounted on the housing part 20 in order. Therefore, a complicated assembly process is not required when assembling using an automatic machine, and it is possible to assemble easily.

Next, a description will be given of a case where the switch unit U performs a detection operation on three different operation directions that should be detected.
When the shift lever 13 is switched from the automatic transmission mode to the manual transmission mode, the second operation lever 17 is not in contact with the operation element 14 as shown in FIG. As shown in FIG. The slide type movable terminal 39 integral with the slider 38 slides in the horizontal direction in conjunction with the pivoting movement of the second operation lever 17, and the operator 14 is pushed to the end as shown in FIG. When the second operating lever 17 is rotated to the tilted position, the contact 51 of the slide-type movable terminal 39 contacts the fifth fixed terminal T5. Accordingly, the fourth fixed terminal T4 and the fifth fixed terminal T5 are brought into conduction, the second switch 12 is turned on, and it is detected that the shift lever 13 has been switched from the automatic transmission mode to the manual transmission mode.

  When the shift lever 13 is further switched to the downshift side after switching to the manual shift mode, as shown in FIG. 7A, the first operating lever 16 is not in contact with the operating projection 15. As shown in FIG. 7B from the standby state, the operation protrusion 15 pushes the downshift operation lever 33 of the first operation lever 16 and gradually rotates the first operation lever 16. In conjunction with this rotating movement, the rotary sliding movable terminal 27 integral with the first operating lever 16 rotates, and as shown in FIG. 7C, the shift down operating lever 33 reaches the rotation limit position. When pressed and rotated, the shift-down contact 27b comes into contact with the second fixed terminal T2. As a result, the first fixed terminal T1 and the second fixed terminal T2 become conductive, the shift down side of the first switch 11 is turned on, and it is detected that the shift lever 13 is switched to the shift down side in the manual shift mode. .

  Further, when the shift lever 13 is further switched to the upshift side after being switched to the manual shift mode, as shown in FIG. 8A, the first operation lever 16 is not in contact with the operation projection 15. As shown in FIG. 8B, the operation projection 15 pushes the shift-up operation lever 34 of the first operation lever 16 and gradually turns the first operation lever 16 from the standby state. In conjunction with this rotating movement, the rotary sliding movable terminal 27 integral with the first operating lever 16 rotates, and as shown in FIG. 8C, the upshift operating lever 34 reaches the rotation limit position. When pushed and rotated, the shift-up contact 27c comes into contact with the third fixed terminal T3. As a result, the first fixed terminal T1 and the third fixed terminal T3 are brought into conduction, the upshift side of the first switch 11 is turned on, and the shift lever 13 is detected to be switched to the upshift side in the manual shift mode. .

  As described above, when a single switch unit having a detection function for detecting external forces in three directions is configured, a three-way contact structure can be configured on the same plane, so that a flattened thin switch unit is configured. it can. Furthermore, when assembling, the housing can be roughly divided into three parts, that is, the housing, the first switch, and the second switch, and the temporary upper surface of the planar first to fifth fixed terminals can be temporarily assembled. Since the assembled switch members can be stacked and assembled sequentially from above, assembly becomes easy. In addition, since the assembly by the automatic machine can be simplified, the assembly efficiency is improved.

In the correspondence between the configuration of the present invention and the configuration of the embodiment,
Although the movable contact piece of the present invention corresponds to the rotary sliding movable terminal 27 of the embodiment, the present invention is not limited to the configuration of the above-described embodiment, and is based on the technical idea described in the claims. Can be applied.
