Abstract

PROBLEM TO BE SOLVED: To attain easy assembly, high accuracy in dimensions, and weight reduction. SOLUTION: This mounting structure is formed with a steering member fixing part 20 forming a gutter-shaped rail on the upper part of the rear wall 13 of a main case 12. A stay part 40 having a body mounting part at its front end, which is integrally-molded with the main case, extends downward from both the ends of the steering member fixing part 20. A steering member 30 having mounting brackets 35, 36 on the side walls of a body at both the ends is laid on the rail and fixed by screwing-in bolts 50 from a fixed wall 22. As a result, the steering member is supported with high rigidity because both the ends thereof are connected with the side walls of a body and the central part is fixed to a floor through the stay part of the main case. With no need for welding the stay part to the steering member, no thermal distortion occurs.

When the steering member 30 is positioned in the rail 23 of the steering member fixing portion 20 by aligning the receiving hole 39 with the female member 37, the female screw 37 of the steering member 30 is aligned with the bolt hole 24 of the fixing wall 22. The steering member 30 is fixed to the fixed wall 2 by inserting the bolt 50 and screwing it into the female screw 37 of the steering member.
2 and fixed. Thereby, an assembly structure in which the steering member 30 and the casing 11 are integrated is obtained.

When the steering member 30 is mounted on the vehicle body, the mounting brackets 35 and 36 at the left and right ends of the steering member 30 are fixed to the side wall of the vehicle body.
The lower end of the vehicle body mounting portion 45 is fixed to the vehicle body floor. Thus, reliable support rigidity of the steering attached to the steering support 38 can be obtained. Although not shown, the front portion of the main case 12 is attached to a dash panel of the vehicle body via a bracket or the like. The front part of the blower case 19 is also attached to the dash panel, and the rear part is attached to the steering member 30 as necessary.

In this embodiment, the steering member fixing portion 20 for forming a gutter-like rail 23 is provided on the rear surface 13 of the main case 12, and the steering member 30 is positioned in the rail 23, and the bolt is provided. 50, the steering member 30 and the casing 11 are assembled together, and the steering member fixing portion 20 is attached to the rear surface 13 of the main case 12.
The steering member 30 is integrally formed with the stay portions 40 extending downward from the left and right ends of the vehicle body. It is supported with high rigidity.

Further, since the positioning pin 25 is provided in the steering member fixing portion 20 and the receiving hole 39 is provided in the steering member 30, the positioning of the steering member 30 when assembling the steering member 30 to the steering member fixing portion 20 is easy. It is. And since the stay part 40 is made of resin integrally molded with the main case 12, the number of constituent parts is small and the weight is light. Similarly, since the stay portion 40 is made of resin and is not welded to the steering member, the number of manufacturing steps is reduced as a whole, and there is no decrease in dimensional accuracy due to thermal distortion during welding.

In this embodiment, the steering member 30 and the casing 11 are assembled into the vehicle body in an integrated state. However, the present invention is not limited to this. First, the casing 11 of the air conditioning unit is mounted on the vehicle body. After the assembly, the steering member 30 may be fixed to the steering member fixing portion 20 of the main case 12.

It should be noted that the stay portion 40 is two extending from both left and right ends of the steering member fixing portion 20.
As a modification, one stay portion may be provided. In this case, as shown in FIG. 4, it is preferable to form the stay 40 on the side close to the steering support 38. Thus, the shape of the casing 11 can be simplified and the weight can be further reduced while maintaining high steering support rigidity via the steering support 38.

FIG. 5 is a sectional view of a steering member fixing portion according to a second embodiment. In this embodiment, the steering member has a rectangular closed cross section. The steering member fixing portion 20A has a female screw 27 provided on the rear wall 13A of the main case 12 corresponding to the bolt hole 24 of the fixing wall 22. The steering member 30 </ b> A
The vertical walls 31A and 34A of the surface have through holes 47 and 48 corresponding to the bolt holes 24 of the fixed wall 22. Bottom wall 21 of steering member fixing portion 20A and steering member 30A
Are provided with positioning pins 25 and receiving holes 39 which are aligned with each other as in the first embodiment.

The steering member 30A is positioned in the rail 23 of the steering member fixing portion 20A by aligning the receiving hole 39 with the positioning pin 25, and the fixed wall 2
The steering member 30A is fastened and fixed to the main case 11 by inserting a bolt 50A from the second bolt hole 24 and passing through the through holes 47 and 48 of the steering member 30A and screwing into the female screw 27 of the main case rear wall 13A. Thereby, an assembly structure in which the steering member and the casing are integrated is obtained.
Other configurations are the same as those of the first embodiment.

According to this embodiment, the same effects as those of the first embodiment can be obtained, and it is particularly suitable for a steering member made of extruded material.

FIG. 6 is a perspective view showing a third embodiment. This is different from the first embodiment in that an audio mounting bracket is provided on the casing of the air conditioning unit. The audio mounting bracket 53 is integrally formed so as to protrude rearward from the rear wall 13 of the main case 12.

The audio mounting bracket 53 is formed by extending the outer wall 41 in the upper half of each stay portion 40 into a flat plate shape toward the interior of the room, and the upper edge thereof is connected to the upper edge of the fixed wall 22 of the steering member fixing portion 20. ing. A flange 54 is provided at the front end on the indoor side, and an audio device (not shown) is located between the audio mounting brackets 53 and fixed to the flange 54 with screws. Other configurations are the same as those of the first embodiment. Thus, the same effects as those of the first embodiment can be obtained, and the merit of further reducing the number of parts and the number of assembling steps can be obtained.

The casing, especially the rear wall of the main case, has the above-mentioned audio mounting bracket,
For example, a mounting bracket or a boss for mounting various components as necessary such as an electronic control unit can be provided.

[0031]

As described above, according to the present invention, the casing of the air conditioning unit is provided with the steering member fixing portion for fixing the central portion of the steering member with bolts, and has the second vehicle body attaching portion to the floor at the tip. Since the stay portion is integrally formed, the steering member is fixed to the vehicle body side wall at both ends thereof, and the center portion is configured to be fixed to the floor via the stay portion, so that the steering member is high. It is supported with rigidity. And since a stay part is formed integrally with the casing, there is an effect that the number of components is small and the weight is light. Further, since the stay is not welded to the steering member, the number of manufacturing steps is reduced, and there is no decrease in dimensional accuracy due to thermal distortion during welding.

In particular, the steering member fixing portion is such that a gutter-like rail having a bottom wall and a fixing wall is formed on a rear wall of the main case, and the steering member is fixed by bolts penetrating the fixing wall. Can be. The positioning pin is provided on the bottom wall of the steering member fixing portion, and the receiving hole corresponding to the positioning pin is provided on the steering member, so that the positioning of the steering member when assembling to the steering member fixing portion is facilitated.
