Vehicle door assembly for electric vehicle and processing method thereof

Abstract

A vehicle door assembly for electric vehicle includes an outer door plate and an inner door plate, wherein the inner door plate is connected with the outer door plate, the outer door plate is an integrated molding structure, and the inner door plate is composed of a plurality of inner plates. A door inner panel includes a first inner panel, a second inn panel, the third inner panel and the fourthinn panel; the first inner panel, the second inner panel, the third inner panel, and the fourth inner panel are connected end-to-end to form a quadrilateral structure, a splint is provided on the first inner panel, a fifth inner panel serving as a beam is provided between the fourth inner panel and the second inner panel, and a sixth inner panel and a seventh inner panel are also provided betweenthe fifth inner panel and the third inner panel. The shape of all the inner panels is designed according to the outer panel of the door, so as to ensure that all the inner panels are attached to the inner surface of the outer panel of the door, and the inner panel of the door is manufactured by splicing several inner panels, thereby avoiding the problem of large local deformation when the inner panel of the door is molded at one time; The invention also discloses a processing method of the automobile door assembly.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to an automobile door assembly for an electric automobile and a processing method thereof. Background technique [0002] In the electric vehicle component system, the car door is one of the main parts of the car body, providing the driver and passengers with access to the vehicle. Existing car doors all include a door outer panel and a door inner panel, and most of the door inner panels are a one-time molding structure, that is, the entire sheet is embedded on the door outer panel, but the door inner panel and the door outer panel formed by the entire sheet are formed at one time. The requirements for panel lamination are relatively high, and high processing accuracy is required to achieve the precise lamination of the inner panel of the door and the outer panel of the door, and the processing cost is relatively high; During assembly, the inner panel of the car door ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a vehicle door assembly for electric vehicles with a simple structure, low processing precision requirements, convenient manufacture, and the door inner panel is composed of splicing and is not easily deformed. The assembly can solve the problems in the prior art that the inner panel of the door made of one-time forming of the whole plate has large local deformation, high processing requirements, and easy to cause damage to the outer panel; the invention also provides a processing of the door assembly for electric vehicles method, this processing method can greatly reduce the deformation rate of the automobile door and improve the product quality
