Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an air conditioner unit fixed to a mounting surface on a cowl top inner side in an instrument panel of a vehicle.

(Prior Art) Conventionally, for cooling and dehumidifying air inside a vehicle, which is arranged between a fan for sucking outside air in a closed cross section of a cowl and a heating unit for supplying warm air. The air conditioner unit is unsightly to the touch, so it is placed inside the instrument panel along with the fan and heating unit. This air conditioner unit
It is a box-shaped unit with an evaporator etc. inside.
As shown in FIG. 3, a flat plate-shaped main bracket 1a protruding upward is provided on a part of the upper wall surface 1h, and the main bracket 1a is opened upward as an intruding portion. The slit portion 1b or the through hole is provided. On the other hand, the screw portion 3a is fixed to the outer surface of the cowl top inner or the outer surface of the cowl top inner bracket 2 attached to the outer surface of the cowl top inner, and the cowl top inner or the cowl top inner bracket of the air conditioner unit 1 is fixed. That is, the cowl top inner side mounting surface 2c is mounted by
The threaded portion 3a is inserted into or inserted into the thread 1b, and in that state, a nut is screwed into the threaded portion 3a.

(Problems to be solved by the invention) When the air conditioner unit is mounted on the mounting surface on the cowl top inner side, as described above, the mounting portion is inside the instrument panel and in a recessed position. In addition, the workability of installation is very poor, and in addition, the screw part 3a
It is not possible to see it, so it is often the case that the nut drops when screwed, but once the nut is dropped, the nut bounces on the upper wall of the air conditioner unit, and I don't know where to go. Since it disappears, there is a problem that the work efficiency is significantly reduced.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a conventional air conditioner unit with both sides of the main bracket and the rear surface of the main bracket facing the mounting surface 2c. Side brackets that are respectively connected to the wall surface and slopes that are connected to the back surface and the side surfaces of the side bracket on the entry side, and that descend from the lower part of the back surface toward the insertion side of the nut. And a section.

(Operation) According to the present invention, the side bracket functions to restrict the movement of the dropped nut in both directions of the main bracket, and the inclined portion makes the dropped nut closer to the operator, that is, the insertion side of the nut. Work to lead to.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

A box-shaped air conditioner unit 11 is integrally formed of resin and has an evaporator or the like having a cooling and dehumidifying function inside, and a part of the upper wall surface 11h thereof projects upward as shown in FIG. Flat main bracket 11a
Is provided, and the main bracket 11a is provided with a slit portion 11b which is opened upward as an intruding portion. Further, when both side portions of the main bracket 11a and the air conditioner unit 11 are mounted on the mounting surface 2c on the cowl top inner side, a surface 11g which is an opposite surface of the mounting surface 2c.
A side bracket 11c is continuously provided on the upper wall surface on the back surface 11d side, and an inclined portion 11f is continuously provided on the back surface 11d and each side surface 11e on the back surface 11d side of the side bracket 11c.

As shown in FIG. 2, the inclined portion 11f is located at a position below the lower end of the slit portion 11b on the back surface 11d, and the nut 2 for mounting
It goes down toward the insertion side of 0 (the direction of the arrow A in FIG. 2), and in the past, it was a flat surface as shown by the chain double-dashed line. Here the main bracket 11 mentioned above
The a, the side bracket 11c, and the inclined portion 11f are integrally formed with the air conditioner unit 11 from resin. On the other hand, a through hole is formed in the cowl top inner bracket 2 attached to the outer surface of the cowl top inner as shown in FIG.
2a is provided, and the bolt head is fixed to the inner surface 2b of the bracket 2 by welding or the like from the through hole 2a.
The threaded portion 13a of 13 projects toward the vehicle rear side (direction of arrow A in FIG. 2). With this configuration, when the air conditioner unit 11 is mounted on the mounting surface 2c of the cowl top inner bracket 2, the screw portion 13a is inserted into the slit portion 11b and the nut 2 is inserted into the screw portion 13a.
0 can be screwed with a tool or by hand, even if nut 2
Even if 0 is dropped, the side bracket 11c restricts the movement of the dropped nut 20 in both sides of the main bracket 11a (direction of arrow B in FIG. 1), and the inclined portion 11f.
Guides the dropped nut 20 to the insertion side of the nut (the direction of the arrow A in FIGS. 1 and 2), so that the dropped nut quickly returns to the operator's hand side, and even if the nut cannot be visually observed. Since the range in which the nut returns will be limited, it will be possible to find it immediately even by fumbling.

Although the mounting surface for the air conditioner unit is provided on the cowl top inner bracket in the above embodiment, it may be directly provided on the cowl top inner. Further, in the above-mentioned embodiment, the intrusion part is a slit-shaped one end of which is open, but it may be a through hole or the like,
The point is that a portion of the bolt for connecting the air conditioner unit and the mounting surface on the cowl top inner side other than the head portion thereof, that is, mainly the screw portion can be inserted.

Further, although the air conditioner unit of the above-mentioned embodiment is integrally molded with resin, the material is not limited to resin, and the main bracket, side brackets, sloped parts, etc. are not integrally molded, but fixed by welding or the like. It may be done. Further, although the air conditioner unit has a box shape in the above embodiment, it is not limited to the box shape, and the heating unit and the fan connected to the evaporator are integrally incorporated. Naturally applicable to existing air conditioner units.

Furthermore, the air conditioner unit of the present invention can be applied to the one in which the inserting direction of the nut does not coincide with the traveling direction of the vehicle.

(Effect of the Invention) As described above, according to the present invention, when the air conditioner unit is mounted on the mounting surface of the cowl top inner side, even if the nut is dropped, it is located at a very limited portion on the insertion side of the nut. Since it returns quickly, it is possible to improve the efficiency of the work of installing the air conditioner unit.
