Embodiment Construction

[0020] As shown in FIG. 1-2 , an anti-collision plate for a car door is arranged on an inner panel 1 of a car door with a closed-loop inner cavity, and the anti-collision plate is fixedly connected with the inner panel 1 of the car door. The anti-collision plate is composed of the anti-collision inner panel 2 and the anti-collision outer panel 3, and is flat as a whole; the anti-collision inner panel 2 is in the shape of "one", and the anti-collision outer panel 3 is "C". " shape or "S" shape or "M" shape; the cross-section of the anti-collision plate is "B" shape; the cross-section of the anti-collision plate is "D" shape; the anti-collision plate and the door The inner panel 1 is welded or riveted or screwed; the anti-collision panel inner panel and the anti-collision outer panel 3 are welded or riveted or screwed; the anti-collision panel and the door inner panel 1 are welded or riveted or screws.

[0021] In the present invention, the anti-collision bar is composed of two...

Abstract

An anti-collision plate for the door of car is a hollow plate with B-shaped or D-shaped cross-section and fixed to the inner plate of door, and is composed of an external plate and an internal plate.

Description

technical field [0001] The invention relates to a car door anti-collision plate. Background technique [0002] With the continuous development of the automobile industry and the maturity of the consumer market, people pay more and more attention to the collision safety of automobiles. In frontal collisions, offset collisions or side collisions at the front of the car, the deformation caused by the door structure will greatly affect the degree of injury of the driver or passengers, and even threaten the lives of the drivers or passengers in severe cases. [0003] At present, in order to solve the above-mentioned problems, the traditional solution is to install an anti-collision bar or anti-collision plate on the inner panel of the car door to strengthen the strength and rigidity of the door panel. However, in the traditional structure, regardless of the "rod" structure or the "plate" structure, there are technical defects: [0004] The main part of the "rod" structure is a ...
