Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a ventilator for a vehicle such as a dual type adopted in an automobile.

[0002]

2. Description of the Related Art A conventional vehicle ventilator structure is shown in FIGS. Reference numeral 1 denotes a housing, which has an opening 1 at the front and rear.
It is formed in a tubular shape having a and 1b. A locking claw 1c protruding downward is provided on the outer lower surface of the housing 1 for mounting a finisher 2 described later. Similarly, a locking claw 1d for mounting a finisher 2 described later is also provided on the outer upper surface. In the vicinity of the rear opening 1b inside the housing 1, a shut outdoor 7 is rotatably supported by a horizontal shaft 7a.

A horizontal louver unit 5 and a vertical louver unit 6 are provided in the front opening 1a inside the housing 1, and the horizontal louver unit 5 includes a plurality of horizontal louvers 5a each having a pair of shafts 5b via a shaft 5b. The horizontal louver frame 5c is rotatably supported on the horizontal louver frame 5c, and similarly, a plurality of vertical louvers 6a are provided via a pair of vertical louvers 6c.
It is rotatably supported on the shaft.

Reference numeral 2 is a finisher, and locking pieces 2c, 2d are provided on the lower side edge and the upper side edge of the finisher 2.
The locking pieces 2c and 2d are locked to the locking claws 1c and 1d provided on the housing 1 so that the finisher 2 is fixed to the housing 1. On the other hand, on the upper side and the lower side of the finisher 2, the upper flange 2a and the lower flange 2b which are brought into contact with the upper edges 3a and the lower edges 4a of the ventilator mounting openings 3 and 4 provided in the instrument panel 3, respectively.
Is provided.

An air guide 8 is provided at the rear end side of the pair of left and right casings 1 and distributes the air from the duct 10 evenly to each casing 1. 11 is a seal.

Therefore, the air supplied from the duct 10 into the passenger compartment is regulated by the shut outdoor 7 to a predetermined amount, and then is directed to the left and right by the vertical louver 6a, and then vertically by the horizontal louver 5a. The structure is such that it is diverted and blown into the passenger compartment.

[0007]

However, in the above conventional structure, the assembly in which the finisher 2 is assembled to the housing 1 is used as the ventilator mounting port 3 of the instrument panel.
The rear end portion of the housing 1 is inserted into the ventilator mounting openings 3 and 4 when it is mounted on the flange 4. However, if it is inserted randomly at this time, the flange 2 protruding below the finisher 2
b and the locking piece 2c projecting on the lower surface of the housing 1 collide with the decorative surface 4b, such as printing, painting, or sheet attachment, which is applied to the edge of the ventilator mounting opening of the instrument panel, There was a problem that the decorative surface 4b was damaged.

The present invention has been made to solve this problem, and when the constituent parts of the ventilator or the assemblies 1 and 2 thereof are inserted into the ventilator mounting openings 3 and 4 provided in the instrument panel, Ventilator which prevents damage to the decorative surface 4b provided on the peripheral edges of the ventilator mounting ports 3 and 4 by the flange 2b and the locking piece 2c protruding from the lower surface of the ventilator assembly and improving the assembling workability. The purpose is to provide the structure.

[0009]

In order to achieve the above object, a vehicle ventilator structure of the present invention has a cylindrical casing having front and rear openings, and is attached to a front opening of the casing. In a ventilator structure for a vehicle, which is provided with a finisher, the housing or an assembly in which the finisher is attached to the housing is inserted and fixed in a ventilator mounting port, two locations facing each other on the left and right sides of the lower surface of the housing. Is provided with a guide rib extending to the ventilator mounting opening along the mounting direction, and the guide rib abuts an opening edge of the ventilator mounting opening to guide insertion of the housing into the ventilator mounting opening.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to the embodiments shown in the drawings. However, in the present invention, in order to achieve the above object, a guide rib 9 is provided on the lower surface of the housing. Since the others are the same as the structure of the conventional example, the same structural parts are denoted by the reference numerals given in the conventional example,
The structural description of the same structure is omitted.

That is, in the embodiment of the present invention, as shown in FIGS. 1 and 2, nine guide ribs are provided so as to oppose each other on the left and right ends of the front part of the outer lower surface of the housing 1 so as to extend along the mounting direction. It is a thing. The guide rib 9 is the inclined surface 9
As shown in FIG. 2, the projection length a of the flat surface 9b having a and the flat surface 9b is the projection length b of the locking piece 2c projectingly provided on the lower surface of the housing 1.
It is longer, and the protrusion 2 is provided until the ventilator assemblies 1 and 2 are completely inserted into the ventilator mounting holes 3 and 4.
It is designed to prevent a problem that b and 2c come into contact with the decorative surface 4b provided on the peripheral edge of the ventilator mounting port and damage the decorative surface 4b.

Therefore, when the ventilator assemblies 1 and 2 are attached to the instrument panel, the guide ribs 9 guide the locking pieces 2c on the lower surface of the housing 1 and the flanges 2b on the lower side of the finisher 2 to make up. Since it does not collide with the surface 4b, damage to the decorative surface 4b can be prevented, and the ventilator can be smoothly inserted and installed in the ventilator mounting port.

[0013]

According to the present invention, the guide rib guides the vehicle ventilator into the instrument panel so that the decorative surface of the instrument panel is not damaged and the assembly workability is greatly improved. is there.
