BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting foot structure for a vehicle air conditioning unit.

[0002]

2. Description of the Related Art In general, an air conditioner for an automobile is manufactured by being divided into a blower unit, a cooler unit, and a heater unit, and these units are attached to a vehicle body to be integrated. This means that a standard car equipped with only a heater can be equipped with an air conditioner as an option. That is, a blower unit and a heater unit are attached in advance as standard specifications, and a cooler unit can be attached between the blower unit and the heater unit when an air conditioner is required later.

Conventionally, as shown in FIG. 3, a lower mounting foot 2 and an upper mounting foot 3 are provided on a cooler unit main body 1 and the main body 1 is inclined to facilitate the retrofitting work of such a unit. In this state, the lower mounting foot 2 is carried into a predetermined position of the vehicle body 4 and temporarily fixed to the lower stud bolt 5 provided on the vehicle body 4. The upper mounting foot 3 is mounted on the upper stud bolt 6 of the vehicle body while being raised in the direction, and the nuts 7, 8 are tightened to the upper and lower stud bolts 5, 6. Also, when the main body 1 is raised in an oblique direction, the upper mounting surface on the vehicle body 4 side is formed diagonally so as to make the upper stud bolts 6 pass through the bolt holes of the upper mounting feet 3 in an oblique manner. Also project obliquely downward.

[0004]

However, in such a conventional structure, the upper stud bolt 6 and the nut 8 are not provided.
When tightening, there is a problem that workability is poor because the main body 1 must be supported by hand so that the main body 1 does not slip off. In a car equipped with an air conditioner as standard equipment, all units are mounted on the vehicle body in the automobile manufacturing line. In this case, each unit must be mounted one by one as described above. Work efficiency was not good. In view of such problems, the present invention locks the lower mounting foot of the main body to the lower stud bolt, and the main body is automatically supported when the vehicle body is raised and the upper mounting foot is mounted on the upper stud bolt. It is an object of the present invention to provide a mounting foot structure for a vehicle air conditioning unit.

[0005]

In order to achieve the above-mentioned object, the present invention is to temporarily lock a lower mounting foot to a lower stud bolt of a vehicle body, raise the unit body, and mount the upper mounting foot on the upper stud of the vehicle body. In the mounting foot structure of the automotive air conditioning unit adapted to be mounted on a bolt, the bolt hole of the upper mounting foot is made slightly smaller than the outer diameter of the upper stud bolt, and the thickness of an edge around the bolt hole is reduced. This is one in which a thin portion is formed.

[0006]

[Function] After the lower mounting foot is locked to the lower stud bolt, when the bolt hole of the upper mounting foot is pressed against the upper stud bolt, the bolt hole is smaller than the upper stud bolt. Is done. As a result, the upper stud bolt is fitted into the bolt hole such that the thin portion jumps over the thread of the stud bolt. Here, even when the hand is released from the main body, the thin portion bites into the thread groove of the stud bolt, so that the main body is temporarily held at the pressed position.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the accompanying drawings. FIGS. 1 and 2 show the upper mounting foot 3 of the cooler unit having the mounting foot structure according to the present invention. The bolt hole 9 of the upper mounting foot 3 is larger than the outer diameter of the upper stud bolt 6 provided on the vehicle body 4. Is also formed small. An oval edge portion around the bolt hole 9 is a thin portion 10 having a smaller thickness than other portions. Specifically, when the upper stud bolt 6 is M6, the diameter of the bolt hole 9 is 5 mm, and the thickness of the thin portion 10 is 0.3 to 0.5 mm. As shown in FIG.
A slit 11 is formed in a cross shape around the center, and is easily deformed. The lower mounting foot (not shown) has a normal bolt hole.

Therefore, the lower mounting foot of the cooler unit is temporarily locked to the lower stud bolt, the main body is raised, and the upper mounting foot 3 is connected to the upper stud bolt 6 of the vehicle body 4 as shown by a two-dot chain line in FIG. When pressed in the direction of arrow P, the thin portion 10 is bent and the hole is enlarged, so that the thin portion 10 jumps over the hill of the upper stud bolt 6 and the upper stud bolt 6 fits into the bolt hole 9. Here, even if the hand is released from the cooler unit, the tip of the thin portion 10 is in a state of being engaged in the thread groove of the upper stud bolt 6, so that the main body is held without being shifted downward. If the structure as in this embodiment is applied to all units of the air conditioner, that is, to the blower unit, the cooler unit, and the heater unit, all the units are temporarily kept in the vehicle body as described above. Thereafter, since the nut tightening work of each unit can be performed at the same time, the work efficiency in the production line is improved.

[0009]

As is clear from the above description, according to the present invention, the thin portion of the bolt hole is engaged with the stud bolt, and the unit body is temporarily held in a partially closed state.
There is no need to support the main body when tightening the nut, so workability is good. Further, after the units constituting the air conditioner are temporarily attached to the vehicle body, all the units can be simultaneously tightened with nuts, thereby improving work efficiency.
