Abstract

A quadrant inner cover for a door of a vehicle is provided to reduce production cost without an adhesive tape and an adhesive and to preclude inflow of wind rush noise effectively by inserting a reinforcing rib of the quadrant inner cover in a cut assembling groove of the soundproof pad. A quadrant inner cover for a door of a vehicle comprises a cover body(100), and a soundproof pad(200). A reinforcing rib(110) is formed on an inner surface of the cover body. The soundproof pad, which is made of a buffer material, is arranged on an inner surface of the cover body. An assembling groove(210) is cut along the outer periphery of the soundproof pad to correspond to the reinforcing rib. The assembling groove is elastically assembled with the reinforcing rib for reducing the production cost and to prevent the inflow of the wind rush noise.

The present invention relates to a vehicle quadrant inner cover of a vehicle, and in particular, to fix a soundproof pad provided on an inner surface of a quadrant inner cover only by its own structure without a separate adhesive tape or adhesive, thereby reducing productivity and improving productivity. It relates to a device that can effectively prevent the inflow of the.

1 is a diagram illustrating a door quadrant inner cover of a general vehicle.

In general, a quadrature inner cover 1 of the front door 2 and an A pillar 3 of the vehicle is provided, and a side mirror (not shown) for securing a rear view is provided on the outer side of the door quadrant inner cover 1. Usually, a tweeter speaker (not shown) is provided inside.

2 is a diagram illustrating a door quadrant inner cover of a conventional vehicle.

As shown in FIG. 2, the door quadrant inner cover of a conventional vehicle is formed by a cover body 10 having a rigid reinforcing rib 11 formed on an inner surface thereof, and an adhesive tape or adhesive on an inner surface of the cover body 10. It is composed of a sound-absorbing pad 20 of the cushioning material.

According to this configuration, the soundproofing pad 20 blocks the wind sound entering the vehicle interior through the side mirror connection portion.

However, the door quadrant inner cover of a conventional vehicle has a limitation on the size of the soundproof pad that can be applied when wind interference is introduced when an interference between the rigid reinforcement ribs and the soundproof pad occurs, and the soundproof pad is attached to the door quadrant inner cover by an adhesive tape or adhesive. There is a technical problem that the production cost is increased because of the adhesion.

The present invention is to solve the above problems, by elastically inserting the rigid reinforcing rib of the quadrant inner cover in the cut groove of the soundproof pad, mutual assembly is possible without a separate adhesive tape or adhesive, as well as reducing the production cost Productivity is improved, and in particular, the sound pad size is not limited to provide a vehicle quadrant inner cover of the vehicle that can effectively prevent the inflow of wind noise.

The present invention relates to a quadrant inner cover provided with a cover body having rigid reinforcing ribs formed on an inner surface thereof, and a soundproof pad of a cushioning material provided on an inner surface of the cover body; An assembly groove is cut in correspondence with the rigid reinforcing rib along the outer circumference of the soundproof pad, and the assembly groove of the soundproof pad is elastically assembled to the rigid reinforcing rib.

3 is a diagram illustrating a door quadrant inner cover of the vehicle of the present invention, and FIG. 4 is a diagram illustrating a soundproof pad applied to the door quadrant inner cover of the vehicle of the present invention.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 3 and 4, the door quadrant inner cover of the vehicle of the present invention has an assembly groove 210 cut in the outer circumference of the soundproof pad 200 to correspond to the shape of the rigid reinforcement rib 110. By assembling the rigid reinforcing ribs 110 between the assembling groove 210 is characterized in that the mutually resilient assembly of the technical features.

Each component of the door quadrant inner cover of the vehicle of the present invention will be described with reference to the drawings as follows.

First, a rigid reinforcing rib 110 is formed on the inner surface of the cover body 100 to reinforce its own rigidity as shown in FIG. 3.

The rigid reinforcing rib 110 is positioned along the outer circumference of the cover body 100, and the soundproof pad 200 having a predetermined thickness having sound absorption and cushioning properties is located therein.

At this time, as shown in Figure 4, the outer circumference of the soundproof pad 200, assembling grooves 210 are formed to cut perpendicularly to the overlapping portion with the rigid reinforcing ribs 110, respectively, this assembling groove 210 The rigid reinforcing rib 110 is elastically inserted as shown in FIG.

Accordingly, the soundproof pad 200 is to maintain the assembled state only in its own structural shape on the inner surface of the cover body 100 without a separate adhesive tape or adhesive.

In particular, since the width of the soundproof pad 200 is not limited by the rigid reinforcement ribs 110, the soundproof pad 200 can be set to have a wider area, and thus the wind sound sound penetrating through the door quadrant inner cover from the outside of the cabin Can be prevented more effectively.

Therefore, the door quadrant inner cover of the vehicle of the present invention cuts the assembly groove 210 on the outer circumference of the soundproof pad 200 in correspondence with the rigid reinforcing rib 110 formed on the inner surface of the cover body 100, thereby assembling the assembly. By resiliently fitting the rigid reinforcing rib 110 into the groove 210, there is no need to use a separate adhesive tape or adhesive, thereby increasing productivity and assemblability, and at the same time, the size of the soundproof pad 200. It is an invention with an excellent advantage that there is no limit to effectively prevent the inflow of wind noise.

The above embodiment is an example for explaining the technical idea of the present invention in detail, and the scope of the present invention is not limited to the above drawings and embodiments.

The present invention as described above by inserting the rigid reinforcement ribs of the quadrant inner cover elastically into the cut-out assembly groove of the soundproof pad, can be mutually assembled without a separate adhesive tape or adhesive to reduce the production cost as well as productivity is improved, in particular Soundproof pad size is not limited is the invention that can effectively prevent the influx of the wind.

Claims (1)
