Background

Vehicle styling plays an important role in people deciding to purchase certain motor vehicles. Thus, a particular vehicle manufacturer may have different styles of doors to match different styles of vehicles, and even similarly sized doors for similarly sized vehicles. Therefore, a new door mold needs to be designed for different vehicles, and the door mold has poor versatility, which increases manufacturing cost and time. The size and shape of the outer door panel must match the model of the vehicle, but for vehicles of similar models, the inner door panel can be used universally. The same door inner plate is matched with different door outer plates, so that the production cost can be reduced, and the production efficiency can be improved.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an improve the car door plant that general door inner panel and different outer boards of door match, this door plant can improve the production efficiency of car door plant, reduction in production cost. Based on this purpose, the utility model discloses a technical scheme as follows:

an automobile door plate comprises an outer door plate, an inner door plate, an extension part and a sound insulation layer, wherein the inner door plate is combined on the outer door plate through the extension part, and door plate universal hardware is installed on the inner door plate; the soundproof layer covers the inner door panel and the extension portion.

Further, the extension part and the inner door plate are fixedly connected through welding, and the extension part and the outer door plate are fixedly connected through rivets.

Further, the door hinge is connected to the universal inner door panel.

Further, the inner door panel and the extension portion are connected by bonding.

Furthermore, the inner door panel is sequentially provided with an upper door panel ornament, a lower door panel ornament and an upper door panel ornament from top to bottom; the door panel upper decoration piece is provided with a car window lifting key mounting hole and a door lock catch hole, and the door panel upper decoration piece is provided with a handle mounting groove; the door plate lower decoration piece is provided with a lamp mounting groove.

Further, at least partial area of the extension part is overlapped with the outer door panel and the inner door panel.

The utility model has the advantages as follows:

(1) in a similar range of door sizes, the universal door inner panel can be matched to different door outer panels by using appropriate extension panels, reducing costs, and enabling style changes to the appearance of a particular vehicle model while minimizing costs and lead times by keeping the same door inner panel and hardware installed on the door. (2) The puigging covers on door inner panel and extension, and the sound insulation effect is better, can make simultaneously between door plant and the extension seem more like a whole, and the impression is better.

Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

Example 1

As shown in fig. 1 to 2, an automobile door panel includes an outer door panel 1, an inner door panel 2, an extension 3 and a soundproof layer 4, the inner door panel 2 is combined on the outer door panel 1 through the extension 3, and door panel universal hardware is installed on the inner door panel 2; the soundproof layer 4 covers the inner door panel 2 and the extension portion 3. Door plant 2 can be general in the car of similar motorcycle type, matches different outer door plant 1, and the size of interior door plant 2 is less than outer door plant 1's size, and extension 3 surrounds the peripheral round of interior door plant 2, and fixes interior door plant 2 on outer door plant 1. The soundproof layer 4 covers the whole inner door panel 2 and the extension part 3, which can improve soundproof effect, and make the door look neat and better in appearance.

The sound insulation layer 4 comprises a cotton layer, a cementing layer and a non-woven fabric layer, wherein the cotton layer is hollow polyester short fiber cotton, and the cementing layer is hot melt fiber with the melting point lower than 150 ℃. The problem that toxic and harmful substances or irritant gases are introduced in the using process of the conventional chemical adhesive is solved by using the hot-melt fibers with the melting point lower than 150 ℃ as the adhesive. And the hollow polyester short fiber cotton replaces polypropylene fiber cotton, so that the hollow polyester short fiber cotton has more favorable sound insulation and heat insulation performance and safety performance, and the self-flame-retardant effect can be realized without adding a flame retardant.

Specifically, the extension portion 3 and the inner door panel 2 are fixedly connected by welding, riveting, bonding, and the like, and similarly, the extension portion 3 and the outer door panel 1 are fixedly connected by riveting, welding, bonding, and the like.

Specifically, the door hinge portion 5 is connected to the universal inner door panel 2.

Specifically, as shown in fig. 3, the inner door panel 2 is provided with a door panel upper garnish 21, a door panel upper garnish 22, and a door panel lower garnish 23 in this order from top to bottom; the door panel upper decoration 21 is provided with a window lifting key mounting hole 211 and a door lock catch hole 212, and the door panel upper decoration 22 is provided with a handle mounting groove 221; the door panel lower garnish 23 is provided with a lamp mounting groove 231.
