A vehicle door for an electric vehicle and a manufacturing method thereof

Abstract

The invention discloses a vehicle door for an electric vehicle, comprising a vehicle door outer plate and a vehicle door inner plate, wherein the vehicle door inner plate is connected with the vehicledoor outer plate, the vehicle door outer plate is an integrated molding structure, and the vehicle door inner plate is formed by splicing and combining a plurality of inner plates. A door inner panelincludes a first inner panel, a second inner panel, a third inner panel, and a fourth inner panel; a first inner panel, a second inner panel, a third inner panel, and a fourth inner panel connected end to end to form a quadrilateral structure, a fifth inner panel serving as a cross member is provided between the fourth inner panel and the second inner panel, and a sixth inner panel and a seventhinner panel are also provided between the fifth inner panel and the third inner panel. As that inn door panel of the invention adopts the process mode of splicing and combining a plurality of inner panel, the problem of large local deformation of the inner door panel is avoided when the inner door panel is for at one time, and the shapes of all the inner panels are designed according to the outerdoor panel, so as to ensure that all the inner panels are adhered to the inner surface of the outer door panel, and then the inner panels are spliced and combined to form an automobile inner panel. The invention also discloses a manufacturing method of the automobile door.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to an automobile door for an electric automobile and a manufacturing method thereof. Background technique [0002] In the auto parts system, the car door is one of the main parts of the car body, providing the passage for the driver and passengers to enter and exit 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 is ...

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 car door for electric vehicles with simple structure, low processing precision requirements, convenient manufacture, and the inner panel of the car door is composed of splicing and is not easily deformed. The car door can solve the problem of In the prior art, the inner panel of the car door made of one-time forming of the whole plate has a large local deformation, high processing requirements, and easy to cause damage to the outer panel; the invention also provides a method for manufacturing an electric vehicle door, which can Greatly reduce the deformation rate of the car door and improve product quality
