Description

  The present invention relates to the structure of an air distribution device used in a vehicle air conditioner or the like.

  Vehicles such as automobiles are provided with air conditioning equipment for adjusting the temperature in the passenger compartment. The air conditioner (so-called HVAC unit) constituting the main part of the air conditioning equipment is provided with an air distribution device for distributing the air for air conditioning between the cold air side and the hot air side (for example, Patent Document 1).

  As shown in FIGS. 25 and 26, the air distributor 12 described above includes the door case 17 having two types of openings 15 and 16, and the two types of openings 15 described above along one surface of the door case 17. , 16 movably disposed between the door member 18, the door attachment portion 21 capable of movably attaching the door member 18 to the door case 17, and the movement of the door member 18 relative to the door case 17. And a door drive mechanism 22 for driving the motor. In addition, the crosspiece part 23 used as the boundary line of both is formed between two types of opening parts 15 and 16. FIG.

  The door attachment portion 21 is located on both sides of the door member 18 and extends in the movement direction of the door member 18 to provide a pair of side plate portions 24 and 25 (guide members) that can guide the movement of the door member 18 described above. I have.

  A guide mechanism 26 is provided between the side plate portions 24 and 25 and the door member 18 (see FIG. 26). In this case, the guide mechanism 26 includes a guide groove 27 extending in the moving direction of the door member 18 at a position substantially opposite to both side portions of the door member 18 in the pair of side plate portions 24 and 25, and a door. It has guide pins 29 projecting from both end positions (upper and lower positions in the figure) of the both sides of the member 18 toward the guide groove 27. Then, the guide pin 29 is slidably fitted along the guide groove 27 so that the door member 18 is guided.

  The door drive mechanism 22 is provided on one surface of the door member 18 (surface opposite to the door case 17) and extends in the moving direction of the door member 18, and the output meshing with the rack portion 34. And a gear 35. The output gear 35 is normally pivotally supported between the pair of side plate portions 24 and 25 using an output shaft 36.

  The door drive mechanism unit 22 is provided with a pair of rack portions 34 on both sides of the door member 18, and a total of a pair of output gears 35 with respect to each of the pair of rack portions 34. In general, the output shafts 36 are connected to each other so as to be interlocked with each other.

  A drive device (not shown) such as a motor is connected to the output shaft 36.

  According to such a configuration, the air distributor 12 operates the door drive mechanism 22 to move the door member 18 attached / held to the door attachment 21, thereby opening the openings 15, 16. The degree can be adjusted.

  That is, the door member 18 is moved to open the opening 15 or the door member 18 is moved to the opposite side to open the opening 16 or the door member 18 is moved to the intermediate position. Thus, both the openings 15 and 16 of the door case 17 can be partially opened with a desired distribution. Thereby, the air for an air conditioning which flows through the inside of an air conditioner can be distributed to the cold wind side and a warm air side.

  At this time, the door member 18 drives a drive device such as a motor (not shown) constituting the door drive mechanism 22 to rotate the output gear 35 via the output shaft 36, and the output gear 35 and the door member are rotated. 18 is moved by changing the meshing position with the rack portion 34 provided on one surface.

  The movement of the door member 18 is guided along the pair of side plate portions 24 and 25 of the door mounting portion 21.

  At this time, in the guide mechanism 26 provided between the side plate portions 24 and 25 and the door member 18, the guide pin 29 is slid along the guide groove 27 to guide the door member 18.

  In the air conditioner described above, the interior is divided into a plurality of zones in the width direction (direction perpendicular to the moving direction) according to specifications.

  When the above-described zone division is performed, the air distribution device 12 is also divided according to the zones, so that each structure described above is divided for each divided zone (for example, zones A, B, and C). Needed independently. Although the door case 17 may be common, the two types of openings 15 and 16 provided in the door case 17 are divided into the number corresponding to the zone with the vertical flange portion 37 extending in the moving direction of the door member 18 as a partition. It is provided adjacent in the width direction.

  Further, when dividing into a plurality of zones, the door drive mechanism 22 of each zone (A, B, C) is installed with the axes of the output shafts 36 aligned with each other as shown in FIG. It is considered the most reasonable and preferable in terms of function and function.

  Therefore, for the intermediate zone (C), since the output shafts 36 of the adjacent zones (A, B) exist on the same axis, it becomes impossible to directly connect the drive device to the output shaft 36. Therefore, measures such as additionally installing the input gear 38 and the input shaft 39 and indirectly connecting a driving device such as a motor via the input shaft 39 are taken.

  At this time, the input gear 38 may be directly meshed with the output gear 35, or the intermediate gear 41 may be interposed between the input gear 38 and the output gear 35. Note that the input shaft 39 is guided to one end of the door case 17 through the side plate portions 24 and 25 such as adjacent zones (A or B, in this case A). Reference numerals 42 and 43 in the figure are bearing members for pivotally supporting the input shaft 39 with respect to the side plate portions 24 and 25.

JP 2001-270317 A

  However, the air distributor has the following problems.

  That is, for example, when the zone division is performed as described above, the door case 17 is provided with a pair of side plate portions 24 and 25 for each zone. Since the shape of the door plate 17 is complicated and the number of the side plate portions 24 and 25 is large, it is difficult to integrally form the door case 17.

  Therefore, it has been studied that at least some of the side plate portions 24 and 25 are provided separately from the door case 17 so that the separate side plate portion 45 can be retrofitted to the door case 17. Thus, when the separate side plate portion 45 is retrofitted to the door case 17, it is necessary to prevent the mounting portion between the door case 17 and the separate side plate portion 45 from interfering with the guide groove 27 described above. There is.

  Here, the guide groove 27 is provided over substantially the entire longitudinal direction of the side plate portions 24 and 25 and the separate side plate portion 45 in order to secure a necessary and sufficient range of movement of the door member 18. Therefore, for example, as shown in FIG. 26, the above-described mounting portion is directly attached to the separate side plate portion 45 with respect to the vertical flange portion 37 from the other surface side (the side opposite to the door member 18) with a screw 46 or the like. If it is fixed in a direction perpendicular to the surface, the guide groove 27 becomes shorter than the required length, and the function is limited. Therefore, another means that does not cause such functional restrictions is required for the mounting portion.

  In order to solve the above-mentioned problems, the invention described in claim 1 is arranged such that a door case having two types of openings and a movable between the two types of openings along one surface of the door case. A door member, and a door mounting portion that can hold the door member movably with respect to the door case, the door mounting portions being located on both sides of the door member, and a moving direction of the door member In the air distribution device structure including a pair of side plate portions (guide members) that can extend to guide the movement of the door member, at least one of the side plate portions is configured separately from the door case Then, the separate side plate portion is slid in the moving direction of the door member between the separate side plate portion and the door case (contact portion), and the slide can be locked to the door case. A locking portion is provided.

  According to a second aspect of the present invention, in the above, a drop prevention portion is provided between the door case and the separate side plate portion, which can prevent the slide locking portion from coming off. Features.

  According to a third aspect of the present invention, in the above, the door drive mechanism unit that drives the movement of the door member with respect to the door case is provided, and the drop-off prevention unit is the door drive mechanism unit in the movement direction. It is provided on the side of the input shaft that constitutes.

  According to a fourth aspect of the present invention, in the above, a gap is formed between the door case and the separate side plate portion, and a contact surface between the door case and the separate side plate portion. It is characterized in that a gap preventing portion capable of preventing the above is provided.

  According to a fifth aspect of the present invention, in the above, the door case has a substantially arc shape or a linear shape in a side view, and a contact surface between the separate side plate portion and the door case is It is characterized by being substantially arcuate or linear in accordance with the side shape of the door case.

  According to invention of Claim 1, the following effects can be acquired by the said structure. That is, by providing a slide locking portion between the separate side plate portion and the door case, the separate side plate portion is easily locked and fixed to the door case by sliding in the moving direction of the door member. Alternatively, it can be attached. Thereby, it is not necessary to form the side plate portion integrally with the door case, and the shape of the door case can be simplified and the door case can be easily formed.

  According to invention of Claim 2, the following effects can be acquired by the said structure. In other words, by providing a drop-off prevention part between the door case and the separate side plate part, the slide locking part inadvertently slides in the release direction, and the separate side plate part comes off the door case. This can be surely prevented.

  According to invention of Claim 3, the following effects can be acquired by the said structure. That is, by providing the above-mentioned drop-off prevention part on the input shaft side of the door drive mechanism part in the movement direction of the door member, the drop-off prevention part is utilized by utilizing the pressing force by the input shaft and the weight of the door drive mechanism part. The anti-separation effect by the prevention part can be further increased.

  According to invention of Claim 4, the following effects can be acquired by the said structure. That is, by providing the gap prevention portion, it is possible to prevent a gap from being formed between the contact surfaces of the door case and the separate side plate portion. Thereby, wind leakage from the contact surface can be prevented.

  According to the fifth aspect of the present invention, the following operational effects can be obtained by the above configuration. That is, by making the contact surfaces of the separate side plate portion and the door case substantially arcuate or linear, they can be matched with each other without any gap. Since the contact surface between the separate side plate portion and the door case has a substantially arc shape, the slide locking portion can be slid and locked and released in an arc shape. The locking part itself can be made more difficult to come off. Further, by making the contact surface between the separate side plate portion and the door case substantially linear, the slide locking portion can be made simpler and easier to mold.

  Hereinafter, embodiments embodying the present invention will be described together with illustrated examples.

  FIGS. 1-24 shows the Example of this invention and its modification. Among these, FIGS. 2 to 10 are Embodiment 1, FIGS. 11 to 15 are Embodiment 2, FIGS. 16 to 22 are Embodiment 3, FIG. 23 is a modification of Embodiment 3, and FIG. This is a modification common to the third embodiment. In addition, in Example 2 and Example 3, its modification, etc., when the code | symbol is abbreviate | omitted for convenience of drawing, it shall handle as what is attached | subjected with the code | symbol same as Example 1. FIG.

  <Configuration> First, a configuration common to the embodiments will be described.

  Vehicles such as automobiles are provided with air conditioning equipment for adjusting the temperature in the passenger compartment. An air conditioner (a so-called HVAC unit) that constitutes a main part of the air conditioning equipment is installed inside a resin instrument panel provided in the front part of the passenger compartment.

  First, the vehicle air conditioner 1 will be described with reference to FIG. The air conditioner 1 includes a body casing 4 having an air inlet 2 and a plurality of air outlets 3 (3a to 3c). An air flow path 5 extending between the air intake port 2 and each air intake port 3 (3a to 3c) is provided inside the main body casing 4. An air introduction fan (not shown) and a cooling heat exchanger 7 are provided in the air flow path 5 in this order from the air inlet 2 side. The air flow path 5 is branched into a bypass flow path 8 and a hot air flow path 9 on the exit side of the cooling heat exchanger 7. Among these, the hot air flow path 9 is provided with a heat exchanger 11 for heating. In addition, an air distribution device 12 capable of distributing the air-conditioning air to the bypass flow path 8 and the hot air flow path 9 is provided at a branch portion (entrance side portion) between the bypass flow path 8 and the hot air flow path 9. ing. In addition, a plurality of outlet door portions 13 (13a to 13c) for selecting and switching the air outlets 3 (3a to 3c) are provided at the joining portion (exit side portion) of the bypass passage 8 and the hot air passage 9. ) Is provided.

  Here, the above-described “cooling heat exchanger 7” is an evaporator (evaporator) configured to cool the air-conditioning air using latent heat of vaporization of the refrigerant used in the air-conditioning equipment of the vehicle. The “heating heat exchanger 11” is a heater core that heats the air-conditioning air using engine cooling water.

  Next, the air distributor 12 will be described with reference to FIGS. 2 to 4 (mainly refer to FIG. 4). The air distributor 12 includes a door case 17 (see FIG. 5) having two types of openings 15 and 16 communicating with the bypass flow path 8 and the hot air flow path 9 of FIG. A door member 18 (see FIGS. 6 and 7) arranged so as to be movable between the two types of openings 15 and 16 along one surface, and the door member 18 is movable with respect to the door case 17. And a door drive mechanism 22 that drives the movement of the door member 18 with respect to the door case 17.

  The door mounting portion 21 is located on both sides of the door member 18 and extends in the moving direction of the door member 18 (in this case, substantially in the vertical direction in the figure) to move the door member 18. A pair of side plate portions 24 and 25 (guide members) capable of guiding are provided.

  A guide mechanism 26 is provided between the side plate portions 24 and 25 and the door member 18. In this case, the guide mechanism 26 includes a guide groove 27 extending in the moving direction of the door member 18 at a position substantially opposite to both side portions of the door member 18 in the pair of side plate portions 24 and 25, and a door. It has guide pins 29 projecting in the width direction from both end positions (upper and lower positions in the figure) of both side portions of the member 18 toward the guide groove 27. Then, the guide pin 29 is slidably fitted along the guide groove 27 so that the door member 18 is guided.

  The door drive mechanism 22 is provided on one surface of the door member 18 (surface opposite to the door case 17) and extends in the moving direction of the door member 18, and the output meshing with the rack portion 34. And a gear 35.

  Here, as a supplementary explanation, the above-described “door case 17” is a resin plate-like body having a substantially rectangular frame shape having a size and shape substantially equal to the cross section of the air flow path 5 described above. Yes. The substantially rectangular frame-shaped door case 17 mainly has upper and lower edges (or upper and lower sides) and left and right edges (or both sides) in the drawing. A seal member 32 for sealing the air flow path 5 is attached to the periphery of the door case 17 (see FIG. 2).

  The two types of “openings 15, 16” each have a rectangular shape having a size approximately half the length of the left and right edges of the door case 17. Between the two types of openings 15 and 16, a horizontal crosspiece 23 serving as a boundary line between them is formed (see FIG. 11). This “horizontal crosspiece 23” is integrally formed with the surface of the door case 17 in a flush state.

  On the other hand, the “door member 18” is a resin-made plate-like body having a substantially rectangular shape with a size capable of closing the openings 15 and 16 described above. A seal member 33 for sealing the door case 17 is attached to the door member 18 at the periphery of the surface on the door case 17 side. In this case, the moving direction of the door member 18 is substantially vertical in the figure.

  The “side plate portions 24, 25” are erected substantially perpendicular to the surface of the door case 17. The side plate portions 24 and 25 are integrally formed with the door case 17 in a normal case.

  The “guide groove 27” corresponds to the guide pin 29 on one end side (for example, the upper end portion) of the door member 18 (for example, the upper end side guide groove) and the other end side (for example, the lower end portion) of the door member 18. Corresponding to the guide pin 29 (for example, a lower end side guide groove).

  The “rack portion 34” is formed integrally with the door member 18. In a normal case, a pair of rack portions 34 are provided along substantially both side portions of the door member 18.

  The “output gear 35” is made of resin. Usually, the output gear 35 is provided in a pair of left and right according to the rack portion 34. The pair of output gears 35 are connected by an output shaft 36 so that they can be interlocked and held together.

  The “output shaft 36” is normally pivotally supported between the pair of side plate portions 24 and 25 at both ends thereof directly or indirectly via a bearing member or the like. In order to prevent the output gear 35 from rotating together, the output shaft 36 has, for example, a rectangular cross section. A drive device (not shown) such as a motor is directly or indirectly connected to the output shaft 36. The output shaft 36 of the output gear 35 is disposed at an intermediate position between the two types of openings 15 and 16.

  In the air conditioner 1 described above, the air flow path 5 is divided into a plurality of zones in the width direction (direction orthogonal to the moving direction) according to specifications. Hereinafter, zone division will be described.

  For example, when the air conditioning environment in the passenger compartment is one, the air flow path 5 is not divided into zones, but the air conditioning environment in the passenger compartment is divided into right and left (driver seat side and passenger seat side). If the air flow path 5 is divided into two zones, and the air-conditioning environment in the vehicle compartment is divided into left and right and rear parts (for the driver seat, front passenger seat, and rear seat), the air flow path 5 Is divided into three zones. In this case, although it divides | segments into three zones (for example, zone A, B, C), it is also possible to divide | segment the air flow path 5 into the zone beyond this further.

  And when dividing | segmenting the above-mentioned zone, since the air distribution apparatus 12 will also be divided according to a zone, the said air distribution apparatus 12 is divided into the said each zone (A, B, C) divided | segmented. Each of these structures is required separately and independently. Although the door case 17 may be common, the two types of openings 15 and 16 provided in the door case 17 are divided into the number corresponding to the zone with the vertical flange portion 37 extending in the moving direction of the door member 18 as a partition. It is provided adjacent in the width direction. Note that the vertical flange portion 37 is usually integrally formed with the door case 17 in a flush state.

  When the air flow path 5 is divided into a plurality of zones, the door drive mechanism 22 in each zone (A, B, C) causes the axes of the output shafts 36 to coincide with each other as shown in FIG. It is the most reasonable and preferable in terms of structure and function.

  Therefore, for the intermediate zone (C), since the output shafts 36 of the adjacent zones (A, B) exist on the same axis, the output shaft 36 (however, in this embodiment, the intermediate zone ( The output shaft 36 of C) has been abolished by devising the support structure of the output gear 35). And a configuration in which a drive device such as a motor is indirectly connected via the input shaft 39 is employed. At this time, the input gear 38 may be directly meshed with the output gear 35, or an intermediate gear may be interposed therebetween. The input shaft 39 passes through the side plate portions 24 and 25 of the adjacent zone (A or B, in this case, A) and is guided to one end of the door case 17. Reference numeral 42 in the drawing denotes a bearing member for supporting the input shaft 39. In this case, since the dimension in the width direction is smaller in the intermediate zone (C) than in the zones (A, B) at both ends, one rack portion 34 and one output gear 35 are provided. The structure has been changed to reduce it one by one.

  In contrast to the above-described common configuration, each of the following embodiments has the following configuration.

(1) Configuration common to each embodiment (embodiments 1 to 3) At least one of the side plate portions 24 and 25 is configured separately from the door case 17 (see FIGS. 8 to 10). Then, the separate side plate portion 51 is slid in the moving direction of the door member 18 as an attachment portion between the separate side plate portion 51 (separate type side plate portion) and the door case 17 to the door case 17. A slide locking portion 52 that can be locked is provided (see FIG. 3).

  Here, the “separate side plate portion 51” may include all the side plate portions 24 and 25 as separate bodies, or may include at least one of the side plate portions 24 and 25 as separate bodies. good. In this case, the intermediate side plate portions 24 and 25 provided at the position of the vertical flange portion 37 of the zone-divided door case 17 are detachable separate side plate portions 51. At this time, the separate side plate portion 51 is further integrated so as to have both functions of the adjacent intermediate side plate portions 24 and 25 (common side plate portion). Therefore, the separate side plate portion 51 has a guide groove 27 for the door member 18 of the adjacent zone on both sides of the separate side plate portion 51 with respect to the standing direction of the separate side plate portion 51 so as not to interfere with each other. The positions are deviated (higher guide groove 27a (zone C) and lower guide groove 27b (zones A and B), see FIG. 18). Correspondingly, the guide pins 29 provided on the door members 18 in the adjacent zones are also provided with their positions shifted with respect to the standing direction of the separate side plate portion 51.

  The side plate portions 24 and 25 provided at the positions of the left and right edge portions of the door case 17 are normal ones integrally formed with the door case 17.

  The “slide engagement portion 52” is provided between the contact portion between the separate side plate portion 51 and the door case 17. The slide locking portion 52 includes a locking claw portion 54 (see FIG. 9) provided on one of the separate side plate portion 51 and the door case 17, and a claw receiving portion 55 provided on the other side (see FIG. 5). And. In this case, the locking claw portion 54 is provided for the separate side plate portion 51, and the claw receiving portion 55 is provided for the door case 17. The locking claw portion 54 and the claw receiving portion 55 can be locked to each other by sliding in the moving direction described above.

  The “locking claw portion 54” (see FIG. 9) is, for example, a hook-shaped portion formed integrally with the contact surface of the separate side plate portion 51 with the door case 17. The hook-shaped portion is, for example, a vertical arm portion that extends substantially in the direction perpendicular to the door case 17 by the thickness of the door case 17, and is substantially parallel to the surface of the door case 17 from the tip of the vertical arm portion and is described above. It has a substantially L shape in a side view integrally including a lateral arm portion extending in the sliding direction (the moving direction of the door member 18). In addition, in order to improve the strength of the connecting portion with the plate surface of the separate side plate portion 51, the vertical arm portion is close to the plate surface of the separate side plate portion 51 on the side surface opposite to the vertical arm portion. You may provide the taper shape etc. which become wide as it does.

  The “claw receiving portion 55” (see FIG. 5) is each locking claw in the vertical flange portion 37 (contact surface with the separate side plate portion 51) on which the separate side plate portion 51 of the door case 17 is provided. It is provided at a position corresponding to the portion 54. The claw receiving portion 55 is a locking shape portion such as a notch portion or a long hole portion that can be locked by moving the locking claw portion 54 in the sliding direction. When the claw receiving portion 55 is a long hole portion, it extends slightly longer than the length of the lateral arm portion in the sliding direction.

  And the slide latching | locking part 52 is provided in at least one place or more, Preferably two places or more. For example, the slide locking portion 52 is substantially positioned at the upper edge of the door case 17 as in the first embodiment (FIGS. 2 to 10) in consideration of the reduction in the number of attachment points and the equalization of the arrangement. And at the three positions of the position of the horizontal crosspiece 23 and the position of the lower edge (configuration of only the slide locking portion 52). Further, as in the second embodiment (FIGS. 11 to 15) and the third embodiment (FIGS. 16 to 22), there are two positions, that is, the position of the upper edge of the door case 17 and the position of the crosspiece 23. It is also possible to provide a mounting auxiliary portion as will be described later at the position of the lower edge of the door case 17 (a configuration in which the slide locking portion 52 and the mounting auxiliary portion are used in combination). The installation location of the slide locking portion 52 is most suitable as described above, but is not limited thereto.

  In each embodiment, the claw receiving portion 55 provided at the position of the upper edge of the door case 17 is a notch, and the claw receiving portion provided at the position of the horizontal rail portion 23 or the position of the lower edge. 55 is a long hole portion. Further, the locking claw portion 54 provided at the position of the upper edge portion of the door case 17 has the above-described vertical arm portion and horizontal arm portion so as not to stick out from the upper edge portion of the door case 17.

In other words, the shape and size of the claw receiving portion 55 and the locking claw portion 54 are individually adjusted so as to be optimal according to the characteristics of the installation position.

  Further, in this case, the locking direction of the slide locking portion 52 is substantially lower so that the own weight of the separate side plate portion 51 can be used for locking, and the release direction resists its own weight. In order not to be released unless a movement is applied, it is almost on the upper side.

(2) Configuration with respect to Embodiment 2 or Embodiment 3 The drop-off prevention portion 57 that can prevent the slide locking portion 52 from (inadvertently) coming off between the door case 17 and the separate side plate portion 51. (See, for example, FIG. 11 and FIG. 18).

  The “drop-off prevention part 57” is an attachment auxiliary part (for example, a lock part) that is provided together with the above-described attachment part (slide engagement part 52) and assists the attachment part. For example, the drop-off preventing portion 57 is a fitting fixing portion 58 as in the second embodiment (FIGS. 11 to 15) or a screw fixing portion 59 as in the third embodiment (FIGS. 16 to 22). And so on. In this case, the drop-off prevention part 57 is provided at the position of the lower edge of the door case 17.

  The “fitting fixing portion 58” of the second embodiment includes, for example, a fitting convex portion 61 (see FIG. 12) integrally formed on a contact surface with the door case 17 in a separate side plate portion 51, and a door. A fitting hole 62 or a fitting recess (hereinafter simply referred to as a fitting hole 62) provided at a position corresponding to the fitting protrusion 61 in the vertical flange portion 37 where the separate side plate 51 of the case 17 is provided. , See FIG. 14). In the fitting fixing portion 58, when the side locking portion 51 is slid and locked to the door case 17 by the slide locking portion 52, the fitting convex portion 61 and the fitting hole portion 62 are in a state of being forcedly fitted. It shall be fitted and not easily removed after fitting. It is structurally possible to provide the fitting hole portion 62 on the door case 17 side and the fitting convex portion 61 on the vertical flange portion 37 side.

  It is preferable that the fitting convex part 61 and the fitting hole part 62 have substantially the same shape and size. For example, the fitting convex portion 61 can be a columnar shape, and the fitting hole portion 62 can be a circular hole having the same diameter as the fitting convex portion 61. Further, the fitting convex portion 61 can be a prismatic shape, and the fitting hole portion 62 can be a square hole having the same shape as the fitting convex portion 61. Or the fitting convex part 61 and the fitting hole part 62 can be made into shapes other than the above. In this case, the fitting convex portion 61 has a triangular prism shape pointed toward the lower end in the figure, and the fitting hole portion 62 has a triangular hole having the same shape as the fitting convex portion 61.

  Moreover, the fitting fixing | fixed part 58 can be made into the shape (for example, taper shape) etc. which have a retaining function.

  Although not particularly illustrated, the drop-off prevention portion 57 can be provided (integrally) with respect to the slide locking portion 52. In this case, for example, the fitting convex portion 61 is provided for one of the locking claw portion 54 and the claw receiving portion 55 of the slide locking portion 52, and the fitting hole portion 62 is provided for the other. To do.

  On the other hand, the “screw fixing portion 59” of the third embodiment corresponds to the boss portion 64 (see FIG. 18) for screwing formed integrally with the separate side plate portion 51 and the boss portion 64 of the door case 17. It is possible to use a tongue piece 65 for screwing or the like that is integrally projected in the out-of-plane direction (one surface side) so as to come into contact with the boss 64 at a position. In this case, the screw fixing portion 59 is provided substantially at the position of the lower edge of the door case 17. The boss portion 64 and the tongue piece portion 65 can be fastened and fixed by screwing screws 66 from the lower side to the upper side in the drawing.

  More specifically, the boss portion 64 is provided in a portion (low-order portion) closer to the door case 17 than the high-order guide groove 27a on the surface of the separate side plate portion 51 where the above-described high-order guide groove 27a is formed. It has been. Or the boss | hub part 64 is provided in the position on the opposite side to the low level guide groove 27b in the surface on the opposite side to the surface in which the above-mentioned low level guide groove 27b was formed of the side plate part 51 of another body.

  At this time, a corner projecting portion 67 for forming the boss portion 64 is formed at the corner portion of the lower edge portion of the door case 17 and the vertical flange portion 37 corresponding to the boss portion 64. It is integrally formed in a flush state.

  Furthermore, a corner notch 68 (see FIG. 20) for preventing interference with the boss 64 is provided at a corner corresponding to the boss 64 of the door member 18. Further, a corner projecting portion 69 (see FIG. 16) is provided at the lower corner portion of the upper opening portion 15 in the drawing to prevent a gap from being formed by the corner notch portion 68 of the door member 18 when fully closed. The door case 17 and the door case 17 are integrally formed. The corner projecting portion 69 has the same shape and size as the corner projecting portion 67 described above.

  Although not specifically illustrated, the door case 17 and the door member 18 may have a flat plate shape, and the above-described contact surface may be substantially linear when viewed from the side (a linear contact surface). In this case, the separate side plate portion 51 has, for example, a side shape as shown in FIG.

  In FIG. 24, the above-described first embodiment is flattened, but the second or third embodiment may be flattened.

  <Operation> Next, the operation of this embodiment will be described.

  First, the operation of the vehicle air conditioner 1 shown in FIG. 1 will be described. The vehicle air conditioner 1 described above can introduce air for air conditioning from the air intake port 2 to the air flow path 5 by driving an air introduction fan (not shown). The air-conditioning air introduced into the air flow path 5 is first cooled by the cooling heat exchanger 7. The air-conditioning air cooled by the cooling heat exchanger 7 is distributed to the bypass flow path 8 and the hot air flow path 9 by the air distributor 12. The air-conditioning air distributed to the bypass flow path 8 flows as it is, and the air-conditioning air distributed to the hot air flow path 9 is heated by the heat exchanger 11 for heating. The air-conditioning air that has flowed through the bypass flow path 8 and the hot air flow path 9 is then merged, and the exit door portion 13 (13a to 13c) moves from the selected air outlet 3 (3a to 3c) to the vehicle interior. It is blown out and used for air conditioning in the passenger compartment.

  Next, the operation of the air distributor 12 shown in FIGS. 2 and 3 will be described. In the air distributor 12 described above, the door drive mechanism 22 is operated to move the door member 18 attached and held by the door attachment 21, thereby opening the bypass passage 8 and the hot air passage 9. The opening degree of 15 and 16 is adjusted.

  That is, by moving the door member 18 and opening (fully opening) the opening 15 that communicates with the bypass flow path 8 of the door case 17, all the air-conditioning air can flow into the bypass flow path 8 (this At that time, the opening 16 is fully closed). Further, the door member 18 is moved to the side opposite to the above, and the opening 16 communicating with the hot air flow path 9 of the door case 17 is opened (fully opened), whereby all air-conditioning air is transferred to the hot air flow path 9. It can flow and can be heated with the heat exchanger 11 for heating (At this time, the opening part 15 becomes fully closed). Further, by moving the door member 18 to the intermediate position described above, both the openings 15 and 16 of the door case 17 are partially opened at a desired distribution, and the air for air conditioning is supplied to the bypass flow path 8 and the hot air flow. It is possible to adjust the amount of air-conditioning air distributed to both of the passages 9 and heated by the heating heat exchanger 11.

  At this time, the door member 18 drives a drive device such as a motor (not shown) constituting the door drive mechanism 22 to rotate the output gear 35 via the output shaft 36, and the output gear 35 and the door member are rotated. 18 is moved by changing the meshing position with the rack portion 34 provided on one surface.

  The door member 18 is guided to move along a pair of side plate portions 24 and 25 (or separate side plate portions 51. The same applies hereinafter) of the door mounting portion 21.

  At this time, in the guide mechanism 26 provided between the side plate portions 24 and 25 and the door member 18, the guide pin 29 is slid along the guide groove 27 to guide the door member 18.

  In this embodiment, the separate side plate 51 is attached to the door case 17 as follows.

  That is, a separate side plate 51 is brought into contact with the door case 17 and is slid in the moving direction of the door member 18. As a result, the locking claw portion 54 of the slide locking portion 52 is locked to the claw receiving portion 55, and the separate side plate portion 51 is locked to the door case 17.

  At this time, if the drop prevention part 57 is provided, the drop prevention part 57 is set. When the dropout prevention part 57 is the fitting fixing part 58, the fitting convex part 61 and the fitting hole part 62 are fitted. Further, when the drop-off preventing portion 57 is the screw fixing portion 59, the boss portion 64 and the tongue piece portion 65 are fastened and fixed by the screw 66.

  Furthermore, when the clearance prevention part 71 is provided, the groove part 72 and the protrusion part 73 are fitted.

  When the separate side plate portion 51 is attached to the door case 17 in this way, the door member 18 and the door drive mechanism portion 22 are attached to the door case 17. At this time, the drop-off prevention portion 57 is provided on the input shaft 39 side of the door drive mechanism portion 22 in the moving direction of the door member 18.

  <Effect> Finally, the effect of this embodiment will be described.

  (1) By providing the slide locking portion 52 between the separate side plate portion 51 and the door case 17, the separate side plate portion 51 is slid in the moving direction of the door member 18 to easily open the door. It can be fixedly secured to the case 17 or attached. Thereby, it is not necessary to form the side plate portions 24 and 25 integrally with the door case 17, and the shape of the door case 17 can be simplified and the door case 17 can be easily formed.

  Also, the above-described slide locking portion 52 can be provided without interfering with the guide groove 27 of the separate side plate portion 51 in terms of structure, so that it is almost unrestricted with respect to the separate side plate portion 51. Can be provided. In addition, since the slide locking portion 52 can be formed so as not to stick out toward the openings 15 and 16, the openings 15 and 16 can be widened accordingly.

  In addition, when the air distributor 12 is assembled, the separate side plate 51 is pressed against the door case 17 by the output shaft 36 and the input shaft 39 of the door drive mechanism 22 and the separate side plate. Since the weight of the door drive mechanism portion 22 acts on the portion 51, the slide locking portion 52 is difficult to come off. Further, when the air distribution device 12 is installed in the air flow path 5 in the main body casing 4 of the air conditioner 1, the movement of the separate side plate portion 51 is restricted by the inner surface of the air flow path 5. The stop part 52 cannot be removed.

  (2) By providing the drop-off prevention portion 57 between the door case 17 and the separate side plate portion 51, the slide locking portion 52 is inadvertently slid in the releasing direction, and the separate side plate portion 51 is It is possible to reliably prevent the door case 17 from coming off.

  The drop-off prevention part 57 can be a fitting fixing part 58, a screw fixing part 59, or the like. When the drop-off preventing portion 57 is the fitting and fixing portion 58, it can be set with one touch. When the drop-off prevention part 57 is the screw fixing part 59, the drop-off prevention can be surely performed.

  Note that the drop-off preventing portion 57 can be provided separated from the slide locking portion 52 or can be provided (integrally) with respect to the slide locking portion 52. When the drop prevention part 57 is provided separately from the slide locking part 52, the slide locking part 52 can be made smaller. Further, when the drop prevention part 57 is provided (integrally) with respect to the slide locking part 52, the drop prevention part 57 can be set simultaneously with the locking operation of the slide locking part 52.

  (3) By providing the above-described drop-off prevention portion 57 on the input shaft 39 side of the door drive mechanism portion 22 in the movement direction of the door member 18, the pressing force by the input shaft 39 and the weight of the door drive mechanism portion 22 are provided. By utilizing the above, it is possible to further increase the anti-separation effect by the drop-off prevention unit 57.

  (4) By providing the clearance prevention part 71, it can prevent that a clearance gap is formed between the contact surfaces of the door case 17 and the separate side plate part 51. Thereby, wind leakage from the contact surface (to the adjacent zone) can be prevented.

  (5) By making the contact surface of the separate side plate portion 51 and the door case 17 substantially arcuate or linear, and matching each other, the two can be aligned without a gap.

  Then, by making the contact surface between the separate side plate portion 51 and the door case 17 substantially arc-shaped, the slide locking portion 52 can be slid and locked and released in an arc shape. Therefore, the slide locking part 52 itself can be made difficult to come off by movement in one direction. Further, by making the contact surface between the separate side plate portion 51 and the door case 17 substantially linear, the slide locking portion 52 can be made simpler and easier to mold.
