Description

Car back door inner panel and car back door

technical field

The utility model relates to the technical field of automobiles, in particular to an inner panel of a back door. The utility model also relates to an automobile back door equipped with the inner panel of the automobile back door.

Background technique

The existing car back door inner panels are all integrated design, that is, the back door lock mounting plate and the back door inner panel are integrally formed. With the increasing curvature of the car back door, the curvature of the back door inner panel It also gradually becomes larger, so that the depth between the highest point of the arc of the back door inner panel and the lowest point of the back door lock position is increased, and the sheet metal at the deepest position of the back door inner panel has the problem of forming cracks. In order to solve the problem of cracking, at present, the support plate of the outer panel of the back door is mostly added to reduce the curvature of the inner panel of the back door, but this solution will cause an increase in the weight of the back door. In addition, for the existing inner panel of the rear door, in order to ensure the shape characteristics of the rear door, no attachment installation point can be designed in the upper area of the door lock installation hole, and the attachment installation point of the rear door can only be designed on the two sides of the inner panel of the rear door. This makes it difficult to design weight-reducing holes on the inner panel of the back door, which is not conducive to the lightweight design of the back door.

Utility model content

In view of this, the utility model aims to propose an automobile back door inner panel to overcome the disadvantages of the existing back door inner panel structure.

In order to achieve the above object, the technical solution of the utility model is achieved in that:

An automobile rear door inner panel, comprising an inner panel body, a rear door lock installation plate is connected to the bottom of the inner panel body, and a rear door lock is formed on the rear door lock installation plate lock mounting hole.

Further, the back door lock mounting plate is welded to the inner panel body.

Further, on both sides of the bottom of the inner panel body, near the edge of the inner panel body, there are accessory installation parts respectively.

Further, the accessory mounting parts are arranged in a plurality at intervals in a line.

Further, on the inner panel body, there are respectively provided lightening holes between the rear door lock installation plate and the accessory installation parts on both sides.

Further, the lightening holes are symmetrically distributed on both sides of the rear door lock mounting plate along the middle line of the inner panel body.

Compared with the prior art, the utility model has the following advantages:

(1) For the inner panel of the automobile back door described in the utility model, by connecting the back door lock installation plate to the inner panel body, the back door lock installation plate is separated from the inner panel body without being separated from the inner panel body. The inner panel body is integrally formed, so that in the design and manufacture of the inner panel of the back door, the inner panel body can be processed separately, and then the back door lock installation plate is connected to the inner panel body, and the back door lock can be adjusted The connection structure between the installation plate and the inner panel body ensures that the installation point of the rear door lock meets the requirements, so as to avoid various problems caused by the processing of the inner panel body due to the consideration of the structure of the door lock installation point in the integral molding. insufficient. The separate design and manufacture of the inner panel body is also convenient for the arrangement of the processing steps, and can also simplify the structural shape of the inner panel body, which is beneficial to design other structures on it.

(2) The accessory installation part is close to the edge of the inner panel body, and the accessory installation part is arranged in a linear shape, which can optimize the structure of the inner panel body, so as to facilitate the setting of weight-reducing holes on the inner panel body.

(3) The weight-reducing holes are set on the inner panel body, which can reduce the weight of the inner panel body, so as to realize the lightweight design of the back door. The symmetrical distribution of the weight-reducing holes on both sides is also conducive to improving the structural stability of the back door after it is installed on the vehicle body.

Another object of the present utility model is to provide an automobile back door, which includes an outer panel of the back door and an inner panel of the above-mentioned automobile back door connected to the outer panel of the back door.

Compared with the prior art, the beneficial effects of the automobile back door of the utility model and the inner panel of the automobile back door are the same, and will not be repeated here.
