Description

  The present invention relates to an air outlet, and more specifically, a cylindrical case member having an air inlet and an air outlet connected to a duct, and a posture displaceable in an air circulation space in the case member. The air outlet is configured to open and close the air circulation space by a displacement of the damper member.

  Various vehicle interior members such as an instrument panel, a floor console, and a roof panel are installed in a vehicle passenger compartment such as a passenger car. An air outlet connected to the air conditioner unit via an air duct is disposed at a required position of these vehicle interior members, and temperature-controlled air sent from the air conditioner unit is directed in an appropriate direction in the vehicle passenger compartment. It comes to blow out.

  FIG. 7 is a schematic perspective view showing the fin-type air outlet in a state where each component is disassembled or omitted, and FIG. 8 is an explanatory sectional view showing the air outlet connected to a duct. . The air outlet AV1 adjusts the air inlet 12 connected to the duct D and the rectangular tubular case member 10 having the air outlet 14 that opens to the passenger compartment, and the direction of the air blown out from the air outlet 14 And a damper mechanism 30 that allows, regulates, or adjusts the air blowing from the air outlet 14. The wind direction control mechanism 20 includes a plurality of lateral fins 22 that are disposed in the vertical direction at required intervals and synchronously displaced by connection members (not shown), and a connection member that is disposed in the left and right directions at required intervals and is not shown. Therefore, by adjusting the angles of the horizontal fins 22 and the vertical fins 24, the blowing direction of the air blown into the passenger compartment can be adjusted vertically and horizontally.

  The damper mechanism 30 is disposed inside the case member 10 on the rear side of the wind direction control mechanism 20 described above, and the air circulation space 15 defined in the case member 10 is in a non-communication state (fully closed state) and a communication state. A damper member 31 whose posture can be displaced so as to be in a (fully opened state), and an operation for disposing the damper member 31 disposed on the outside (lower side) of the case member 10 in a state of being connected to the damper member 31. The member 34 is comprised. The damper member 31 has support holes formed on the upper wall portion and the lower wall portion of the case member 10 with rotational support shafts 36 and 36 projecting on the same axis at the center of the upper end edge and the center of the lower end edge of the damper body 32. By being fitted to 16, 16, the posture of the case member 10 can be rotationally displaced. The operation member 34 is rotatably disposed on a support shaft 18 projecting from the lower side of the case member 10, and a fingertip operation unit 34 </ b> A exposed from the front panel portion 10 </ b> A of the case member 10 to the passenger compartment, and a damper main body. And a lever portion 34B that engages with a connecting member 38 that is mounted on a rotation support shaft 36 on the lower side.

Therefore, when the operation member 34 is rotated to the front right via the fingertip operation unit 34A, the operation member 34 is rotated counterclockwise in FIG. 8 as indicated by a two-dot chain line in FIG. The damper member 31 is displaced in the posture to the first position where the air circulation space 15 in the case member 10 is in a non-communication state, and restricts air from being blown out from the air outlet 14. Further, when the operating member 34 is rotated to the front left direction via the fingertip operating portion 34A, the operating member 34 is rotated clockwise in FIG. 8 as indicated by a solid line in FIG. Is displaced to the second position where the air circulation space 15 in the case member 10 is in a communicating state, and air is allowed to blow out from the air outlet 14. Although the damper mechanism illustrated in FIGS. 7 and 8 is a link mechanism, although not shown, there are other mechanisms that use a gear mechanism. Such an air outlet damper structure is disclosed in, for example, Patent Document 1 and Patent Document 2.
JP 2003-341356 A JP 2000-335234 A

  By the way, the damper structure illustrated in FIG. 7 and the damper structures disclosed in Patent Document 1 and Patent Document 2 both have the rotation support shafts 36 and 36 provided on the damper main body 32 of the damper member 31 on the case member 10. The damper member 31 is rotated around the rotation support shafts 36 and 36 that are fixedly (immovable) by being fitted into the corresponding support holes 16 and 16 provided, so-called “fixed rotation”. Type ". Therefore, as shown in FIG. 8, when the damper member 31 is displaced to the second position, the seal portion 33 provided on the outer peripheral portion of the damper main body 32 interferes with the vertical fins 24 of the wind direction control mechanism 20. In order to prevent this, it is necessary to set the support holes 16, 16 on the rear side of the case member 10 in accordance with the outer size of the damper member 31. Accordingly, when the damper member 31 is displaced to the first position, the seal point SP at which the seal portion 33 comes into contact with the inner wall surface of the case member 10 is the air blowing of the case member 10 as shown in FIG. Since the position is considerably deeper from the outlet 14, the total length L1 of the case member 10 is inevitably increased, and the problem of increasing the size and weight of the air outlet AV1 is inherent.

  Furthermore, with the increase in size of the air outlet AV1, the following harmful effects have occurred. That is, in the vehicle interior member IP such as an instrument panel, since various other in-vehicle devices and parts are arranged inside the vehicle interior member IP, as illustrated in FIG. There is a restriction that the distance H from the rear end face of the duct D cannot be set large. In such a case, the vicinity of the air outlet D1 of the duct D to which the air outlet AV1 is connected, that is, the downstream end portion D2 of the duct D is bent at a substantially right angle, and the duct bend R becomes small. The inner bend R becomes considerably small. For this reason, air flow is likely to be disturbed inside the bent downstream end portion D2, causing an increase in flow resistance and a decrease in flow speed, resulting in a problem that the flow efficiency deteriorates.

  In addition, as is clear from FIG. 8, the damper member 31 described above is almost located in the case member 10 even if the posture is displaced to the second position, and therefore the damper member 31 is bent so as to face the air outlet D1 of the duct D. There was almost no function to rectify the circulating air in the downstream end portion D2. In other words, the conventional air outlet has no idea of causing the damper member 31 to have a rectifying function.

  Accordingly, an object of the present invention is to provide a duct structure for an air outlet which can be reduced in size by reducing the outer size and can improve the flow efficiency of air flowing in from the duct.

In order to solve the problem and achieve the intended object, the invention according to claim 1

In the damper member, the second support part moves to the inner wall surface side of the case member in the second guide part, and the first support part moves to the air outlet side in the first guide part. while in the attitude displaced to the first position to the fully closed state the air flow space, the second supporting portion is moved to the middle side of the air flow space in the second guide portion, the first support portion is the By moving to the air introduction port side in the first guide portion, the posture is displaced to the second position that is the middle of the direction that intersects the air flow direction in the air flow space, and the air flow space is made fully open. The gist.

Therefore, according to the second aspect of the invention, in the first position, the damper member is displaced in the posture toward the air outlet and the air circulation space is fully closed, so that the overall length of the case member can be shortened. Thus, the air outlet can be reduced in size and weight. Also, since the duct bend R at the downstream end portion of the duct connected to the air outlet can be set large so that the downstream end portion can have a gently curved shape, the air flowing into the air outlet from the duct The distribution efficiency can be improved, and an increase in distribution resistance and a decrease in distribution speed can be avoided to improve distribution efficiency.

According to a third aspect of the present invention, the second guide portion approaches the air outlet side from the intermediate side in the direction intersecting the air flow direction in the air flow space toward the inner wall surface side of the case member. The main point is that
Therefore, according to the third aspect of the present invention, since the first support portion and the second support portion move along the first guide portion and the second guide portion due to the attitude displacement of the operation member , the damper member becomes the case member. The posture is displaced while being supported stably.

The gist of the invention described in claim 4 is that the damper member extends from the air inlet into the duct by a required amount at the second position .
Therefore, according to the invention which concerns on Claim 4, since the damper member which moved to the 2nd position comes to extend in a duct, it becomes possible to have a rectification | straightening function together in a damper member.

  According to the air outlet of the present invention, there is an advantage that the outer size can be reduced to reduce the size, and the flow efficiency of air flowing in from the duct can be improved.

  Next, the air outlet according to the present invention will be described below with reference to the accompanying drawings by way of preferred embodiments. In the embodiments described later, the same members / parts as those already shown in FIGS. 7 and 8 will be described with the same reference numerals. In the embodiments described later, for convenience of explanation, the side facing the passenger compartment from the vehicle interior member IP (air outlet side) is the “front side” of the air outlet, and the side connected to the duct D (air inlet side). This is the “rear side” of the air outlet.

  FIG. 1 is an explanatory sectional view showing an air outlet according to the present embodiment connected to a duct, and FIG. 2 is a schematic view showing the air outlet according to the present embodiment in a state where each component is disassembled or omitted. It is a perspective view. The air outlet AV of the present embodiment is basically the same as the conventional air outlet AV1 illustrated in FIGS. 7 and 8, and an air inlet 12 connected to the duct D and an air outlet 14 opening to the passenger compartment. A rectangular tube-shaped case member 10, a wind direction control mechanism 20 that adjusts the blowing direction of the air blown from the air blower outlet 14, and a damper mechanism that allows, regulates, or adjusts the blowout of air from the air blower outlet 14. 60. And the damper mechanism 60 containing the damper member 62 mentioned later is changed, It is characterized by the above-mentioned.

  The case member 10 has an air circulation space 15 defined therein, and a frame-shaped front panel portion 10A is formed at a front portion thereof, and an operation member 64 described later faces below the front panel portion 10A. An opening 40 is formed. A first support hole 42 is formed in the left wall portion and the right wall portion to rotatably support the horizontal fins 22 in the wind direction control mechanism 20, and the vertical fins 24 are formed in the upper wall portion and the lower wall portion. A second support hole 44 is formed to rotatably support the. Further, on the rear side of the upper wall portion and the lower wall portion, a guide groove 46, in which a first support portion 66, 66 and a second support portion 68, 68 provided on a damper member 62 described later are slidably fitted. 46 is formed. Further, a support shaft 18 for projectingly supporting the operation member 64 is provided on the outer side of the front portion of the lower wall portion. In such a case member 10, as illustrated in FIG. 1, the front panel portion 10 </ b> A is aligned with the mounting opening B of the vehicle interior member IP, and the rear end portion is connected to the air outlet D <b> 1 of the duct D. The inside of the duct D and the inside of the case member 10 (the air circulation space 15) are communicated spatially.

  The air direction control mechanism 20 is basically the same as the conventional air outlet illustrated in FIG. 7, and is arranged in a plurality of horizontal positions that are arranged in the vertical direction at required intervals and that are synchronously displaced by a connecting member (not shown). The fins 22 are composed of a plurality of vertical fins 24 that are disposed at required intervals in the left-right direction and that are displaced in posture synchronously by a connecting member (not shown). Slide levers 52 for adjusting the angles of the horizontal fins 22 and the vertical fins 24 are arranged on the horizontal fins 22 installed at the upper and lower centers. The angle of each horizontal fin 22 can be adjusted by twisting, and the angle of each vertical fin 24 can be adjusted by sliding the slide lever 52 in the left-right direction. Therefore, by adjusting the angles of the vertical fins 24 and the horizontal fins 22, it is possible to adjust the blowing direction of the air blown into the passenger compartment through the air outlet 14 in the vertical and horizontal directions.

  The damper mechanism 60 according to the present embodiment is disposed inside the case member 10 on the rear side of the wind direction control mechanism 20 described above, and the air circulation space 15 in the case member 10 is in a non-communication state (fully closed state) and a communication state. A damper member 62 whose position can be displaced so as to be in a state (fully opened state), and disposed on the outside (lower side) of the case member 10 in a state of being connected to the damper member 62, for displacing the damper member 62. The operation member 64 is comprised. Then, by the fingertip operation with respect to the operation member 64, the damper member 62 is moved to the first position (FIGS. 3 and 4) where the air circulation space 15 is not in communication and the second position where the air circulation space 15 is in communication. The posture can be displaced as shown in FIGS.

  In the damper mechanism 60 of the present embodiment, the damper member 62 housed in the case member 10 moves while sliding in the case member 10 (air circulation space 15), thereby opening and closing the air circulation space 15. It is characterized by the displacement of the posture. In order to realize such sliding movement, the damper member 62 includes first and second support portions 66 and 66 that are slidably fitted into the above-described guide grooves 46 and 46 at the upper and lower edges of the damper main body 63, respectively. Supporting portions 68 and 68 are projected. Here, the guide grooves 46, 46 formed in the upper wall portion and the lower wall portion of the case member 10 are formed in the longitudinal direction of the case member 10, that is, in the air circulation space 15, as illustrated in FIGS. 1 and 2. From the first guide portion 48 extending in the same direction as the flow direction and the second guide portion 50 extending in the short direction of the case member 10, that is, in the direction intersecting the air flow direction in the air flow space 15. As a whole, it is bent into a “substantially square shape”. In the guide groove 46 formed in the lower wall portion, only the second guide portion 50 is a through hole, and the insertion of the second support portion 68 described above can be allowed.

  Accordingly, the damper member 62 includes the first support portions 66 and 66 disposed so as to be movable in the air flow direction by sliding along the first guide portions 48 and 48 of the guide grooves 46 and 46, and the guide grooves. It has the 2nd support parts 68 and 68 arrange | positioned so that it can move to the direction which cross | intersects an air distribution direction by sliding along the 2nd guide parts 50 and 50 of 46,46. As a result, the posture displacement of the damper member 62 is caused by the first support portions 66, 66 and the second support portions 68, 68 based on the operation of the operation member 64, as will be described later, in the first guides 46, 46, respectively. By moving along the parts 48 and 48 and the second guide parts 50 and 50, the parts move while sliding along a curve.

  The operating member 64 is formed on a circular main body 70 rotatably disposed on a support shaft 18 projecting from the lower side of the case member 10, and is formed on an end surface of the main body 70, so that the front panel 10 </ b> A is formed. A fingertip operating portion 72 exposed to the passenger compartment from the opening 40 and a lever portion formed on the end surface of the main body portion 70 and engaged with the second support portion 68 extending from the second guide portion 50 of the guide groove 46. 74, 74. Accordingly, by rotating the operation member 64 using the fingertip operation part 72 with the fingertip, the lever parts 74 and 74 move in the direction opposite to the fingertip operation direction, thereby moving the second support part 68. Will come to let you.

  For example, as illustrated in FIGS. 3 and 4, when the fingertip operation unit 72 is moved rightward in the front direction, the operation member 64 rotates counterclockwise in FIG. 3, and the lever portions 74 and 74 are moved leftward. Therefore, the second support portion 68 moves to the left end of the second guide portion 50 in the guide groove 46. As a result, the damper member 62 moves to the left end of the corresponding second guide portion 50, 50, and the first support portion 66, 66 corresponds to the corresponding first guide portion 48. 48, as shown in FIG. 3, the position of the case member 10 is displaced while sliding to the first position where the case member 10 is brought into a non-communication state.

  On the other hand, as illustrated in FIGS. 5 and 6, when the fingertip operation unit 72 is moved to the front left direction, the operation member 64 rotates clockwise in FIG. 5 and the lever portions 74 and 74 move to the right direction. In order to move, the second support portion 68 moves to the right end of the second guide portion 50 in the guide groove 46. As a result, the damper member 62 moves to the right end of the corresponding second guide portion 50, 50 with the respective second support portion 68, 68, and the first guide portion 48 with the corresponding first support portion 66, 66. , 48 are moved to the rear ends, and as illustrated in FIG. 5, the case member 10 is displaced while being slid to the second position where the case member 10 is in the communication state.

  That is, in the damper mechanism 60 of the present embodiment, the first support portions 66 and 66 and the second support portions 68 and 68 are in the same direction as the air flow direction (longitudinal direction of the case member 10) based on the fingertip operation of the operation member 64. Further, the damper member 62 is displaced in posture by moving in the direction intersecting with the air flow direction (short direction of the case member 10). In other words, the damper member 62 moves in the longitudinal direction (front-rear direction) of the case member 10 unlike the conventional damper member 31 to which the rotation support shaft 36 that is a hinge point is fixed. The posture is displaced between the positions.

  Thus, when the damper member 62 is displaced to the first position, the rear side of the damper member 62 moves while sliding forward as shown in FIG. The seal point SP at which the seal portion 76 provided in the portion contacts the inner wall surface of the case member 10 is at a position offset forward by a required amount W as compared with the conventional air outlet AV1 illustrated in FIG. Therefore, the total length L of the case member 10 can be shortened by an amount corresponding to the above-described required amount W as compared with the total length L1 of the case member 10 of the conventional air outlet AV1 illustrated by a two-dot chain line in FIG. It becomes possible.

  Even if the distance H between the inner wall surface of the vehicle interior member IP and the duct D is the same as the overall length of the case member 10 is reduced and the outer size of the air outlet AV is reduced, the air outlet AV is reduced. The duct bend R of the downstream end portion D2 of the duct D leading to the AV can be set large, and the downstream end portion D2 can have a gentle curved shape. That is, in the conventional air outlet AV1 illustrated in FIG. 8, as illustrated by a two-dot chain line in FIG. 3, the entire length of the case member 10 is as large as L1, and therefore the duct D reaching the air outlet AV1 is connected to the downstream end portion D2. However, when the air outlet AV of this embodiment is adopted, the entire length of the case member 10 is L, so that the downstream end portion of the duct D It is possible to make D2 be a gently curved shape and to increase the inner bend R.

  Accordingly, the flow of air inside the downstream end portion D2 of the duct D is smooth, and it is difficult for the air flow in this portion to be disturbed. Therefore, the flow efficiency is deteriorated due to an increase in flow resistance and a decrease in flow speed. Can be suitably avoided.

  Further, in the air outlet AV of the present embodiment, since the entire length of the case member 10 is shortened to L, when the damper member 62 is displaced to the second position, as shown in FIGS. 1 and 5. In addition, the rear portion 63A of the damper main body 63 on the rear side of the first support portions 66, 66 extends rearward from the air inlet 12 into the duct D while moving backward. Accordingly, the rear portion 63A of the damper main body 63 has a shape that is curved in accordance with the curved shape of the downstream end portion D2 of the duct D, that is, a shape that follows the air flow path in the duct D (downstream end portion D2). This is considered to function as a current plate. That is, in the damper mechanism 60 of the present embodiment, the damper member 62 whose posture is displaced to the second position is used to be positioned at the air outlet D1 of the duct D and the air inlet 12 of the air outlet AV. A rectifying function for further rectifying the flow of air flowing into the case member 10 from the duct D is also provided.

  Therefore, according to the air outlet according to the above-described embodiment, the following operational effects can be obtained. That is, since the damper member 62 disposed in the case member 10 is displaced while sliding so as to open and close the air circulation space 15, the overall length L of the case member 10 can be shortened. There is an advantage that the outer size of the air outlet AV can be reduced and the weight can be reduced. Since the two support portions of the first support portions 66 and 66 and the second support portions 68 and 68 move in a predetermined direction, the damper member 62 appropriately moves while moving in the air flow direction in the air flow space 15. The posture is displaced. In addition, the damper member 62 has the first support portion 66 and the second support portion 68 that move along the first guide portion 48 and the second guide portion 50 of the guide groove 46 provided in the case member 10. The posture is displaced while it is stably supported by the robot.

  Further, as the air outlet AV is made smaller and more compact, the duct bend R of the downstream end portion D2 of the duct D connected to the air outlet AV can be set large, so that the downstream end portion D2 has a gently curved shape. It becomes possible. Accordingly, since the air flowing into the air outlet AV from the duct D can be smoothly distributed, an increase in the distribution resistance, a decrease in the distribution speed, and the like can be avoided, and the distribution efficiency can be improved.

  Further, as the air outlet AV becomes smaller and more compact, the damper member 62 that has moved to the second position extends into the duct D. Therefore, the damper member 62 can have a rectifying function. Moreover, if the rear portion 63A of the damper main body 63 extending into the duct D is shaped along the air flow path of the duct D (downstream end portion D2), it flows into the air outlet AV from the duct D. Since the air can be more smoothly distributed, further improvement in the distribution efficiency can be expected.

  In addition, the connection structure of the damper member 62 and the operation member 64, the shape of the operation member 64, etc. are not limited to the form of the Example mentioned above, It can implement by applying various forms. For example, the guide grooves 46 and 46 are formed on the rear side of the left and right side wall portions of the case member 10, and the first support portions 66 and 66 and the second support portions 68 and 68 protrude from the left and right edges of the damper main body 63. Even if the first support portions 66 and 66 and the second support portions 68 and 68 are slidably fitted into the corresponding guide grooves 46 and 46, the air flow space 15 of the case member 10 can be used. The posture of the damper member 62 can be appropriately displaced.

  An air outlet according to the present invention includes a cylindrical case member having an air inlet and an air outlet connected to a duct, and a damper member disposed in an air circulation space in the case member so as to be capable of posture displacement. The air outlet is configured to open and close the air circulation space according to the displacement of the damper member, and can be suitably implemented in an air outlet installed in various vehicle interior members.
