Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for an air outlet for an air conditioner provided in an instrument panel of an automobile.

As shown in Fig. 1, when a long air outlet 1 made of synthetic resin or the like is attached to the instrument panel main body 6, the air outlet has a long length due to the difference in thermal expansion coefficient between the instrument panel main body and the air outlet. It may be deformed in the direction.

The present invention provides a structure for attaching such a long air outlet in a manner that allows the expansion and contraction caused by heat to be easily and accurately absorbed, and the embodiments shown in FIGS. 2 and 3 will be described below.

In the present invention, a long air outlet 1 is divided into two in the longitudinal direction, and split air outlets 2 and 3 are combined to form a structure.

A cylindrical boss portion 2 is provided at the center end of one of the divided air outlets 2.
A connecting flange 3a is integrally formed with a connecting flange 2a having a portion b protruding rearward, and a connecting flange 3a having a hole 3b into which the boss portion 2b fits at the center end of the other divided air outlet 3.
are formed integrally, and the boss portion 2b is fitted into the hole 3b to connect both the connecting flanges 2a, 3a, and as shown in FIG. 3, the instrument panel main body or the member 4 connected thereto is overlapped. By screwing the squirrel 5 into the end face of the boss portion 2b, the surface-divided air outlets 2 and 3 form a connected elongated air outlet 1, and the central portion of the air outlet 1 is fixed to the instrument panel side.

Flange portions 2c, 3 are provided on the outer periphery of the front edges of the surface-divided air outlets 2, 3.
c is integrally formed in a protruding manner, and faces the flange portions 2c and 3c with a predetermined gap 2e and 3e at the rear of the flange portions 2c and 3c on the side outer end surface of the surface-divided air outlet 2.3. The locking portions 2 d and 3 d are each provided integrally.

When installing the air outlet 1 as described above on the instrument panel,
A locking portion 2d provided on the outer end surface of each side when the surface-divided air outlets 2 and 3 are not connected.

Fit the gaps 2e and 3e between the flange parts 3d and the flange parts 2c and 3c into both side edges of the opening of the instrument panel main body 6, and then connect the split air outlet 2.3fj to the connecting flange 2a as described above.
, 3a are joined together and stacked on the member 4 on the instrument panel side, and connected and fixed with screws 5.

Then, the flange parts 2c, 3c are brought into contact with the outer edge of the opening of the instrument panel body 6 on the entire outer periphery of the outlet 1, and the outlet 1 is brought into contact with the locking part 2d on both sides in the longitudinal direction.
, 3d and the flange portions 2C, 3C sandwich the instrument panel main body 6, and the locking portions 2d, 3d are locked to the panel portion 6a on the back side of the instrument panel main body 6, and the flange portion 2C
, 3C come into elastic contact with a pad portion 6b made of synthetic resin or the like provided on the outer surface of the panel portion 6a, and the air outlet 1 is firmly held.

Also, the gaps 2e and 3e that sandwich the instrument panel body 6 allow for relative expansion in the longitudinal direction of the air outlet 1 due to heat.

The contraction is absorbed by the gaps 2e, 3e and the relative sliding in the longitudinal direction of the instrument panel body 6 fitted therein,
The air outlet 1 will not be deformed.

As described above, according to the present invention, the installation work of the long air outlet to the instrument panel is extremely easy due to the extremely simple configuration.
In addition, it can accurately absorb relative expansion and contraction due to the difference in thermal expansion between the air outlet and the instrument panel that supports it, and can bring about great practical effects.
