BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a blower unit mounted on an insulator dash attached to the interior of a dash panel and a cowl box panel. The blower unit mounting structure.

[0002]

2. Description of the Related Art For example, as shown in FIG. An insulator dash 3 having a soundproof function is installed. The insulator dash 3 is composed of a two-layer structure in which a sound absorbing material 5 such as a felt or a soft polyurethane foam is laminated on the back side of a sound insulating material 4 such as a PVC sheet or a rubber sheet.

An air conditioning unit such as a blower unit 6 is usually installed below the cowl box panel 2, and as shown in FIG.
The insulator dash 3 is also formed with an opening 3a slightly larger than the opening 2a, which is attached to the surface of the insulator dash 3 and introduces outside air into the unit 6 through the opening 2a of the cowl box panel 2.

In order to maintain the sealing performance of the opening 3a, a sealing member 7 is provided on the opening flange 6a of the blower unit 6.

[0005]

As described above, the blower unit 6 installed below the cowl box panel 2
Is conventionally mounted in the X direction in FIG. 6, that is, from the lower side to the upper side. However, in recent years, the rationalization and automation of the automobile assembly line have been advanced, and when the mounting of the blower unit 6 by a robot is attempted, The Y direction in FIG. 6, that is, the mounting direction of the unit 6 tends to be restricted in the front-back direction of the vehicle.

Accordingly, when the robotization is promoted, the opening flange 6a of the blower unit 6 is connected to the opening 3a of the insulator dash 3 as shown in FIGS.
It has been pointed out that the rear edge of the blower unit cannot be expected to perform a smooth mounting operation of the blower unit 6.

In order to solve this problem, as shown in FIG. 9, when the opening 3a of the insulator dash 3 is made large and the opening 3a is extended to the boundary between the dash panel 1 and the cowl box panel 2, Although the blower unit 6 can be automatically mounted, there is a problem that the soundproofing function of the insulator dash 3 is significantly reduced.

The present invention has been made in view of such circumstances, and has a blower unit mounting structure that enables automatic mounting of the blower unit (the mounting direction is the front-rear direction of the vehicle) without impairing the soundproof performance. It is intended to provide.

[0009]

In order to achieve the above object, according to the present invention, an opening is formed in an insulator dash attached to a vehicle interior surface of a dash panel and a cowl box panel. Correspondingly,
In the mounting structure of the blower unit which is mounted on the insulator dash by sliding along the front-rear direction, the opening has a narrower width on the front side than on the back side, and the insertion edge of the opening flange in the blower unit. Are set so as to be located outside of both sides of the opening of the insulator dash, and when the blower unit is mounted, the blower unit is mounted while lifting the opening edge of the insulator dash by the insertion edge.

[0010]

As is apparent from the above configuration, the width of the opening in the insulator dash becomes narrower toward the near side, and both ends of the insertion edge of the opening flange of the blower unit are located closer than both sides of the opening of the insulator dash. Since the blower unit is located on the outside, when the blower unit is attached to the insulator dash along the front-rear direction of the vehicle, the insertion edge of the opening flange of the unit dash even if the rear edge of the opening of the insulator dash hangs downward. Since the insulator dash advances while being lifted on both sides, the drooping is restricted, and the rear edge of the opening of the insulator dash does not hit the opening flange of the blower unit.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view showing an embodiment of a blower unit mounting structure according to the present invention;

FIGS. 1 and 2 show a first embodiment of a blower unit mounting structure according to the present invention. FIG. 1 is a longitudinal sectional view showing a unit mounting structure, and FIG. 2 is a diagram showing a unit mounting operation. 1 is a view as viewed in the direction of arrow A in FIG.

FIG. 3 is an explanatory view showing a unit mounting operation similar to FIG. 2 showing a second embodiment of the blower unit mounting structure according to the present invention, and FIG. 4 is a second embodiment of the blower unit mounting structure according to the present invention. It is sectional drawing which shows 3 Example.

A first embodiment of the present invention will be described with reference to FIGS.

Referring to FIG. 1, an insulator dash 10 for an automobile according to the present invention includes a sound insulating material 11 having a relatively large surface density, such as a PVC sheet or a rubber sheet, and a felt or a soft polyurethane integrally adhered to the back surface of the sound insulating material 11. It is composed of a laminate with the sound absorbing material 12 made of a porous base material such as a foam, and is attached and fixed to the interior surface of the dash panel 20 and the interior surface of the cowl box panel 30.
Dash panel 20 and cowl box panel 30
To prevent the noise and vibration of the engine from the engine room E from propagating into the vehicle interior R, thereby maintaining a good quietness in the vehicle interior.

Various air conditioners are installed below the cowl box panel 30. In this embodiment, an example of installation of the blower unit 40 will be described.

The blower unit 40 is attached to the bottom of the cowl box panel 30, and blows outside air through the opening 31 of the cowl box panel 30.
Introduce within.

Therefore, the opening 13 larger than the opening 31 formed on the bottom surface of the cowl box panel 30 is also formed on the insulator dash 10.

The features of the present invention are to improve the sealing performance of the peripheral portion of the opening 13 formed in the insulator dash 10 and to smoothly mount the blower unit 40 even if the mounting direction of the blower unit 40 is set in the front-rear direction of the vehicle. An object of the present invention is to provide a mounting structure of the blower unit 40 which can secure the performance.

That is, the shape of the opening 13 of the insulator dash 10 is smaller than that of the rear side 13a.
The width of b is set to be small, and the shape of the opening flange 41 of the blower unit 40 is, as shown in FIG. When the dimension of the insertion edge 42 is set to b so that both ends of the insertion edge 42 of the opening flange 41 do not cover the opening 13, b>
a is set.

Therefore, when the blower unit 40 is slid and mounted at a predetermined position below the cowl box panel 30, the insertion edge 42 of the opening flange 41 of the blower unit 40 has both ends on both sides of the opening 13 of the insulator dash 10. The blower unit 40 advances so as to lift the blower unit, and the rear edge of the opening 13 and the opening flange 41 do not come into contact with each other as in the related art, so that the blower unit 40 can be smoothly and automatically mounted.

In the drawing, reference numeral 43 denotes an opening flange 41.
2 shows a seal member attached to the first embodiment.

As described above, according to the present invention, by changing the shape of the opening flange 41 in the blower unit 40, the blower unit 40 can be automatically mounted and the opening 13 formed in the insulator dash 10 can also be installed. Since the opening 31 of the cowl box panel 30 can be set to have substantially the same shape as that of the conventional structure shown in FIG. 9, the sealing performance is greatly improved.

FIGS. 3 and 4 show another embodiment of the mounting structure of the blower unit according to the present invention. In the second embodiment of the present invention shown in FIG. In this embodiment, the protrusions 44 are formed on both sides of the edge 42 so as to face in the insertion direction. When the blower unit 40 is automatically mounted, the protrusions 44 provided on the opening flange 41 of the blower unit 40 correspond to the openings 13 of the insulator dash 10. Since the mounting of the blower unit 40 is performed while lifting the edge, there is an advantage that the workability is further improved as compared with the first embodiment.

Next, in a third embodiment of the present invention shown in FIG. 4, a guide portion 45 is formed by bending the tip of the insertion edge 42 of the opening flange 41 of the blower unit 40 downward, or a blower is provided. The guide portion 45 may be formed with the tip of the convex portion 44 formed on the opening flange 41 of the unit 40 facing downward. This embodiment also improves the workability of the blower unit 40.

[0026]

As described above, the blower unit mounting structure according to the present invention has the following special effects.

(1) The width of the opening in the insulator dash is set to be narrower on the near side than on the back side, and both ends of the insertion edge of the opening flange in the blower unit are located outside both sides of the opening of the insulator dash. When the blower unit is automatically mounted below the cowl box panel, the insertion edge of the opening flange of the blower unit is mounted while lifting the opening edge of the insulator dash. Does not hit the rear edge of the opening of the insulator dash, and the blower unit can be automatically mounted by the robot.

(2) The width of the opening in the insulator dash is set narrower on the near side than on the back side, and both sides of the insertion edge of the opening flange in the blower unit are set outside the both sides of the opening of the insulator dash. As a result, even if an opening having substantially the same shape as the opening of the cowl box panel is formed in the insulator dash, the blower unit can be automatically mounted, so that the sealability of the insulator dash around the blower unit mounting portion is greatly improved, This has the effect that the quietness of the vehicle interior can be significantly improved.
