Description

  The present invention relates to a structure for fixing a vehicle air conditioner disposed in a vehicle interior of a vehicle to a vehicle side member.

  Conventionally, for example, an instrument panel is disposed in a front portion of a passenger compartment of an automobile or the like, and a vehicle air conditioner is accommodated in the instrument panel. Since this vehicle air conditioner is large and heavy, for example, as disclosed in Patent Document 1, it is directly fixed to a vehicle side member such as a vehicle floor panel or dash panel. The vehicle side member is provided with a stud bolt as a fixing shaft that protrudes toward the vehicle rear side. The air conditioner is provided with a mounting portion. The mounting portion is formed with a fixing surface that comes into contact with a nut as an engaging member that is engaged with and engaged with the stat bolt, and the fixing surface has a circular fixing hole through which the stud bolt is inserted. Is open. Such a fixing surface is normally formed so as to extend in a direction orthogonal to the fastening direction, that is, a direction orthogonal to the center line of the stud bolt. Therefore, the fixing surface of Patent Document 1 is in the vehicle width direction. It extends to.

When mounting the air conditioner, first, the air conditioner is arranged on the rear side of the vehicle with respect to the stud bolt, and then moved to the front side to insert the stud bolt into the fixing hole of the air conditioner. Then, a nut is screwed onto the stud bolt to fasten and fix the attachment portion to the vehicle side member.

  However, when the air-conditioning apparatus is directly fixed to the vehicle side member using the stud bolt and nut as in Patent Document 1, for example, the center line of the stud bolt extends in the vehicle front-rear direction under the structural restrictions of the vehicle. In some cases, it may be necessary to provide a tilt. In this case, since the fixing surface of the mounting portion needs to be orthogonal to the center line of the stud bolt, the fixing surface is also inclined with respect to the vehicle width direction so as to correspond to the inclination of the stud bolt. Further, when the stud bolt is tilted with respect to the vehicle longitudinal direction as described above, the mounting portion moves to the front side of the vehicle when the air conditioner is mounted. Will cross. Therefore, if the air conditioner is moved to the front side of the vehicle when the air conditioner is mounted, the stat bolt will move relative to the fixed surface from the front side of the vehicle to the rear side, and thus the fixing surface of the mounting portion. The fixing hole that opens in the hole must be formed in an elongated hole shape so as to correspond to the movement locus of the stud bolt that moves relative to the fixing hole.

  When the fixing hole is in the shape of a long hole in this way, when fastening the mounting part, the part corresponding to the shape of the long hole in the nut faces the part where the fixing hole is opened and does not contact the fixing surface. Compared with the case where the entire circumference of the nut is in contact with the fixed surface as in the case where the hole is circular, the contact area of the nut with the fixed surface is reduced.

  In addition, the position of the fixing hole of the air conditioner and the position of the stud bolt of the vehicle side member are different for each individual due to manufacturing error. Therefore, the fixing hole should be set large so that this manufacturing error can be absorbed. There is a demand to improve the mounting workability. If the fixing hole is set to be large, the contact area of the nut is further reduced in addition to the reduction of the contact area of the nut to the fixing surface due to the elongated hole shape of the fixing hole described above.

  If the contact area of the nut to the fixed surface decreases in this way, there is a possibility that the mounting portion cannot be firmly fixed. Therefore, it is conceivable to increase the contact area to the fixed surface by increasing the nut. However, such nuts must be specially manufactured, and if specially manufactured, the number of types of nuts at the assembly work site increases, resulting in management man-hours, etc., and manufacturing costs. Invite to soar.

  The present invention has been made in view of such a point, and the object of the present invention is to fix the fixing hole when the center line of the fixing shaft of the vehicle-side member intersects the moving direction when the air conditioner is mounted. By elaborating the shape, manufacturing errors occurring in each member can be absorbed when the air conditioner is installed to improve the mounting workability, and the engaging member that engages the fixing shaft can be enlarged. The mounting portion can be firmly fixed to the vehicle side member, and the manufacturing cost is kept low.

  In order to achieve the above object, according to the present invention, one side of the fixing hole in the longitudinal direction is set as an insertion start region where the fixing shaft starts to be inserted, and the other side in the longitudinal direction is set as an insertion completion region of the fixing shaft. The peripheral edge of the start area is formed to be separated from the outer peripheral surface of the fixing shaft by a predetermined distance, and the peripheral edge of the fixing hole insertion completion area is set to the outer peripheral surface of the fixing shaft when the vehicle air conditioner is in the final stage of mounting. The mounting portion is fixed to the vehicle-side member by a fixing shaft and an engaging member that are formed so as to be closer than the predetermined distance.

Specifically, in the first aspect of the present invention, the vehicle air conditioner is moved to the mounting position set in the vehicle interior, and the mounting portion provided in the vehicle air conditioner is used as the vehicle side member constituting the vehicle. The vehicle air-conditioning apparatus is fixed to the vehicle air-conditioning apparatus, the mounting position of the vehicle air-conditioning apparatus is set on the vehicle rear side of the vehicle-side member, and the moving direction when the vehicle air-conditioning apparatus is mounted Is a direction from the rear side of the vehicle toward the front side. The vehicle side member protrudes toward the mounting portion of the vehicle air conditioner, and the center line intersects the moving direction when the vehicle air conditioner is mounted. And a fixing shaft extending so that the distal end portion is located on one side in the vehicle width direction with respect to the base end portion , and the mounting portion extends in a direction orthogonal to the center line of the fixing shaft. A fixed surface and an opening in the fixed surface through which the fixing shaft is inserted A fixed hole is formed, and the fixing hole has an elongated hole shape extending so as to correspond to a movement locus of the fixing shaft that moves relative to the mounting portion when the vehicle air conditioner is mounted. One side in the longitudinal direction is an insertion start region where the fixing shaft begins to be inserted in the initial stage of mounting the vehicle air conditioner, and the other side in the longitudinal direction is the fixing area in the final stage of mounting the vehicle air conditioner. The insertion completion region where the shaft is located is an intermediate region between the insertion start region and the insertion completion region, and the peripheral portion of the insertion start region of the fixing hole is in the initial stage of installation of the vehicle air conditioner Sometimes it is formed so as to be separated from the outer peripheral surface of the fixing shaft by a predetermined distance, and the peripheral portion of the fixing hole insertion completion region is the outer peripheral surface of the fixing shaft when the vehicle air conditioner is in the final stage of mounting. Is closer than the predetermined distance Is urchin formed, vertical center of the insertion start region of the fixing hole is positioned above the vertical center of the insertion completion region, the peripheral portion of the intermediate region of the fixing hole from the periphery of the insertion start region The attachment portion is formed by the fixing shaft that is formed to extend linearly to the peripheral edge portion of the insertion completion region and is positioned in the insertion completion region of the fixing hole, and an engagement member that engages with the fixing shaft. It is set as the structure fixed to the said vehicle side member.

  According to this configuration, when the vehicular air conditioner is in the initial stage of mounting, the insertion start area of the fixing hole and the outer peripheral surface of the fixing shaft are greatly opened by opening the fixing hole insertion start area. A predetermined distance is secured longer. As a result, when the fixing shaft starts to be inserted into the fixing hole, manufacturing errors occurring in the fixing hole and the fixing shaft are absorbed, and the interference of the fixing shaft with the peripheral portion of the fixing hole is suppressed. The fixing shaft can be smoothly inserted into the fixing hole. When the vehicle air conditioner is moved to the final stage of mounting, the fixing shaft relatively moves to the fixing hole insertion completion region. When the engagement member is engaged with the fixing shaft in the insertion completion region, the engagement member comes into contact with the periphery of the insertion completion region of the fixing hole in the fixing surface. At this time, the peripheral portion of the insertion completion region in the fixing hole is closer to the outer peripheral surface of the fixing shaft than the predetermined distance in the initial stage of mounting, and the insertion completion region of the fixing hole is opened smaller than the insertion start region. As a result, a large contact area of the engaging member to the fixed surface is ensured without increasing the size of the engaging member.

Moreover , it becomes possible to arrange | position to a mounting position by moving a vehicle air conditioner to the front side, after positioning it in the vehicle rear side of a vehicle side member. When the vehicle air conditioner is moved in the vehicle front-rear direction in this way, the vehicle air conditioner may be displaced downward from the normal mounting position due to the weight of the entire instrument panel. In this case, by positioning the center of the insertion start region of the fixing hole above the center of the insertion completion region of the fixing hole in advance, the mounting portion, that is, the fixing hole, at the initial mounting stage of the vehicle air conditioner However, even if the weight of the entire instrument panel is displaced downward from the normal mounting position, the fixing shaft can be prevented from interfering with the peripheral portion of the insertion start region of the fixing hole. And the attaching part located in the insertion completion area | region of a fixing hole is fixed to a vehicle side member in a regular mounting position.

Further , when the vehicle air conditioner is moved to the mounting position, when the fixing shaft inserted in the insertion start region of the fixing hole is relatively moved to the insertion completion region, it is suppressed from being caught by the peripheral portion of the fixing hole. Is possible .

  According to the first aspect of the present invention, when the fixing shaft intersects the moving direction at the time of mounting the vehicle air conditioner, the mounting workability of the vehicle air conditioner is greatly increased by opening the fixing hole insertion start region. In addition, the mounting hole can be firmly fixed without opening the engaging hole insertion completion area smaller than the insertion starting area and increasing the size of the engaging member, thereby reducing the manufacturing cost. be able to.

Also , when the moving direction when moving the vehicle air conditioner to the mounting position is the vehicle front-rear direction, the vertical center of the insertion start area of the fixing hole is positioned above the vertical center of the insertion completion area. Even if the fixing hole is displaced downward from the normal mounting position due to the weight of the entire instrument panel, the fixing shaft can be smoothly inserted into the fixing hole at the initial stage of mounting. Thus, the mounting portion can be fixed at a proper position while further improving the mounting workability of the vehicle air conditioner.

In addition , since the peripheral portion of the intermediate region of the fixing hole is formed in a straight line, when the vehicle air conditioner is moved to the mounting position, it is possible to prevent the fixing shaft from being caught by the peripheral portion of the fixing hole. This makes it possible to further improve the mounting workability of the air conditioner for a vehicle .

The output shaft of the blowing direction switching actuator 101 is a link member at the left end portion of the rotating shaft 110b. (Not shown). When the second blowing direction switching door 110 rotates upward, the vent outlet 106 is fully closed and the passage leading to the defroster outlet 105 is fully opened. Moreover, when the 2nd blowing direction switching door 110 rotates below, the vent blower outlet 106 will be fully opened and the channel | path which reaches the defroster blower outlet 105 will be fully closed.

  The blowing mode is switched by rotating the first blowing direction switching door 100 and the second blowing direction switching door 110, respectively. When the first blowing direction switching door 100 is rotated upward to close the lower side of the distribution passage 98 below the communication port 99, the conditioned air is in the foot mode in which the conditioned air is blown out from the lower ends of the foot outlet 103 and the distribution duct 97.

In this state, when only the second blowing direction switching door 110 is rotated upward, the conditioned air is blown out from the defroster outlet 105. Moreover, when the 1st blowing direction switching door 100 is made into the intermediate position of a rotation range, and the 2nd blowing direction switching door 110 is rotated upwards, conditioned air will be the foot blower outlet 103, the lower end part of the distribution duct 97, and a defroster. In this state, when only the second blowing direction switching door 110 is rotated downward, the conditioned air is turned into the foot blowing port 103, the lower end portion of the distribution duct 97, and the vent blowing port 106. It becomes the bi-level mode that blows out.

As shown in FIG. 13, the outer shape of the fixing portion 116 is a pentagon corresponding to the shape of the discharge hole T1, and is fitted to the peripheral edge of the discharge hole T1 while being inserted into the discharge hole T1. It has become. In addition, since the fixing portion 116 is pentagonal, the condensate guide member 7 is rotated around the center line of the discharge hole T1 by being engaged with the peripheral portion of the discharge hole T1 while being inserted into the discharge hole T1. Is being prevented.

  As shown in FIG. 12, in the vicinity of the fixing portion 116 of the receiving portion 115, a plate-like extending portion 122 extending outwardly of the receiving portion 115 and extending in an annular shape is formed. As shown in FIGS. 13 and 14, a piece 122 a that protrudes to the left is formed on the left edge of the extension 122. A rubber plate-like sealing material 124 is attached to the lower surface of the extending portion 122. This sealing material 124 is in pressure contact with the peripheral edge portion of the discharge hole T1 of the floor panel FP, and seals between the peripheral edge portion of the discharge hole T1 and the lower surface of the extending portion 122.

  As shown in FIGS. 12 and 13, engagement claws 125 are provided on the left and right sides of the fixing portion 116. The engaging claw 125 protrudes outward from the fixed portion 116 and is elastically deformed in the inner and outer directions of the fixed portion 116. When the fixing portion 116 is completely inserted into the discharge hole T1, the engaging claw 125 is positioned below the floor panel FP and engages with the peripheral edge of the discharge hole T1 from below. As a result, the fixing portion 116 is prevented from coming out of the discharge hole T1.

  As shown in FIG. 12, the front support leg 117 has a plate shape extending from the front part of the receiving part 115 so as to protrude to the front side, and is separated downward from the flange 119. About half of the base end side of the front support leg 117 extends substantially parallel to the flange 119. About half of the front end side of the front support leg 117 extends so as to be slightly inclined downward toward the front side. A columnar portion 117 a extending in the left-right direction is integrally formed at the front end portion of the front support leg portion 117. A plurality of ribs 120 extending so as to be continuous with both are provided between about half of the base end side of the front support leg 117 and the flange 119. About half of the front end side of the front support leg 117 is elastically deformed in the vertical direction. The front ends of the front support legs 117 and the rear support legs 118 abut on the upper surface of the floor tunnel T, so that the receiving section 115 is prevented from tilting greatly.

  Next, a procedure for mounting the air conditioner 1 configured as described above on a vehicle will be described. First, the instrument panel module IM is configured by attaching the components other than the condensed water guide member 7 of the vehicle air conditioner 1 to the instrument panel P. The instrument panel module IM is manufactured, for example, at a location different from the vehicle manufacturing line. Before the instrument panel module IM is mounted on the vehicle on the vehicle production line, the fixing portion 116 of the condensed water guide member 7 is inserted into the discharge hole T1 of the floor tunnel T, and the condensed water guide member 7 is placed on the floor tunnel T. Secure to the wall. In a state where the condensed water guide member 7 is fixed to the floor tunnel T, the fixing portion 116 is engaged with the peripheral portion of the discharge hole T1, and the engaging claw 125 is engaged with the peripheral portion of the discharge hole T1 from below. Furthermore, the outer surface of the fixing portion 116 engages with the peripheral edge of the discharge hole T1, and the rotation of the condensed water guide member 7 is prevented.

  Thereafter, the instrument panel module IM is transported into the passenger compartment. At this time, because the condensed water guide member 7 is removed from the instrument panel module IM, the vertical dimension of the instrument panel module IM is shortened. For this reason, the instrument panel module IM can be easily moved to the mounting position in the passenger compartment R. When moving in the passenger compartment R, first, as shown in FIGS. 3A and 15, the instrument panel module IM is positioned behind the mounting position. Then, it moves to the front side substantially horizontally to the mounting position. During this horizontal movement, the bottom wall portion 37a of the air conditioner 1 may come into contact with the condensed water guide member 7, but the condensed water guide member 7 is fixed to the floor tunnel T and held at a predetermined position as described above. Therefore, the position shift of the condensed water guide member 7 is suppressed.

  Further, when the instrument panel module IM is moved to the mounting position, the mounting leg 76 of the air conditioner 1 moves to the front side, and at the initial stage of mounting, as shown in FIG. It is inserted into the insertion start area 77 a of the fixing hole 77. At this time, as described above, the peripheral portion of the insertion start region 77 a is formed so as to be separated from the outer peripheral surface of the stud bolt C by a predetermined distance L or more, so that the stud bolt C interferes with the peripheral portion of the fixing hole 77. The stud bolt C can be smoothly inserted into the fixing hole 77.

  When the instrument panel IM is further moved forward after the stud bolt C is inserted into the insertion start area 77 a, the stud bolt C is moved relative to the fixing hole 77 to the insertion completion area 77 b. When the air conditioner 1 shakes in the middle of this, the stud bolt C may come into contact with the peripheral edge of the intermediate region 77 c of the fixing hole 77. At this time, since the peripheral edge portion of the intermediate region 77c extends linearly, it is possible to suppress the stud bolt C from being caught by the peripheral edge portion of the fixing hole 77.

  At the final stage of mounting the instrument panel module IM, the stud bolt C is positioned in the insertion completion region 77b of the fixing hole 77 as shown in FIG. As shown in FIG. 4B, a nut N is screwed into the stud bolt C to fasten and fix the mounting leg 76 to the dash panel DP. At this time, since the peripheral portion of the insertion completion region 77b in the fixing hole 77 and the outer peripheral surface of the stud bolt C are closer than those in the initial stage of mounting, the size of the nut N can be increased without increasing the size of the nut N. A wide contact area with the fixed surface 76c is ensured.

  In a state where the instrument panel module IM is mounted on the vehicle, the sealing material 74 of the flat portion 71 of the air conditioning unit casing 38 is in pressure contact with the upper surface of the flange 119 of the condensed water guide member 7, and the flat portion 71 and the flange 119 are sealed. Is done.

As described above, according to the vehicle air conditioner fixing structure according to this reference example , when the stud bolt C intersects the moving direction when the air conditioner 1 is mounted, the insertion start region of the fixing hole 77 is inserted. 77a can be opened greatly to improve the mounting workability of the air conditioner 1, and the insertion completion area 77b of the fixing hole 77 is opened smaller than the insertion start area 77a, and the size of the nut N is not increased. The attachment portion 76 can be firmly fixed to the dash panel DP, and the manufacturing cost can be kept low.

  Moreover, since the peripheral part of the intermediate region 77c of the fixing hole 77 is formed in a straight line, the stud bolt C can be prevented from being caught on the peripheral part of the fixing hole 77, and the mounting workability of the air conditioner 1 is further improved. be able to.

(Embodiment)
In the reference example , the vertical center of the insertion start region 77a of the fixing hole 77 and the vertical center of the insertion completion region 77b are located at the same height, but as in the embodiment shown in FIG. The vertical center P of the insertion start area 77a may be positioned above the vertical center Q of the insertion completion area 77b. That is, when the air conditioner 1 is moved in the front-rear direction at the time of mounting as described above, the air conditioner 1 is displaced downward from the normal mounting position by the weight of the entire instrument panel P during the movement. Sometimes. In this case, the fixing hole 77 is also displaced downward from the normal position. At this time, the center P of the insertion start area 77a is positioned in advance above the center Q of the insertion completion area 77b, so that the stud bolt It is possible to suppress C from interfering with the peripheral edge portion of the insertion start region 77 a of the fixing hole 77. Thereby, the mounting workability of the air conditioner 1 can be further improved.

Further, the shape of the insertion start region 77a of the fixing hole 77 is not limited to an arc shape, and may be formed in a square shape as in the reference example shown in FIG.

Further, as in the reference example shown in FIG. 16C, the opening width dimension L3 on the insertion completion area 77b side of the intermediate area 77c of the fixing hole 77 is equal to the opening width dimension L2 of the insertion completion area 77b (FIG. 4A). It may be set substantially the same as that shown in FIG. In this reference example , when the stud bolt C is positioned in the insertion completion region 77b of the fixing hole 77, the opening width of the fixing hole 77 on the insertion start region 77a side with respect to the stud bolt C is substantially the same as the insertion completion region 77b. Can be made narrower. This makes it possible to secure a wider contact area of the nut N with the fixing surface 76c, and to firmly fix the mounting leg 76 to the dash panel DP.

Further, in this embodiment, the case where the stud bolt C is inclined so as to be positioned on the left side as it goes to the tip side has been described, but the present invention is such that the stud bolt C is positioned on the right side as it goes to the tip side. The present invention can also be applied to a case where it is inclined to the angle. In this case, what is necessary is just to incline so that the attachment leg of the air conditioner 1 may be located in the right side, so that it goes to the front side .
