Vehicle door anti-collision plate, preparation method of vehicle door anti-collision plate and vehicle door

Abstract

The invention discloses a vehicle door anti-collision plate, a preparation method of the vehicle door anti-collision plate and a vehicle door, and belongs to the field of vehicle parts. The vehicle door anti-collision plate comprises thickness-reduced metal anti-collision plates and a fiber-reinforced body integrated with the metal anti-collision plates by a compression molding process. Accordingto the vehicle door anti-collision plate provided by the invention, by adopting the thickness-reduced metal anti-collision plates, the weight of the vehicle door anti-collision plate can be effectively reduced; and on the basis of reducing the weight of the vehicle door anti-collision plate, in order to improve the anti-collision performance of the vehicle door anti-collision plate, the fiber-reinforced body and the metal anti-collision plates are integrated by the compression molding process, and because the fiber-reinforced body has high mechanical performance, the vehicle door anti-collision plate has high strength and wear resistance. The vehicle door anti-collision plate provided by the embodiments of the invention can simultaneously meet the requirements of light weight and high mechanical performance, namely realizes higher anti-collision performance on the premise of reducing the weight.

Description

Technical field [0001] The invention relates to the field of auto parts, in particular to a car door anti-collision plate, a preparation method and a car door. Background technique [0002] The door anti-collision plate, also known as the door reinforcement plate, is installed between the door inner panel and the door outer panel to provide support for the door outer panel, thereby improving the door's anti-collision performance. Therefore, it is necessary to provide a door anti-collision plate. [0003] At present, sheet metal processing and stamping processes are usually used to shape sheet metal to obtain the door anti-collision plate. [0004] The inventor found that the prior art has at least the following problems: [0005] The vehicle door anti-collision plate provided by the prior art has a relatively heavy weight, which is not conducive to the lightweight of the vehicle body. Summary of the invention [0006] The embodiment of the present invention provides a vehicle door an...
