Reinforcing plate for bumper bar below vehicle door

Abstract

The invention discloses a reinforcing plate for a bumper bar below a vehicle door. The reinforcing plate comprises a plate body (1), wherein the plate body (1) adopts a recumbent Omega shape and comprises a first straight part (3), a second straight part (4) and a circular arc part (5); the circular arc part (5) adopts a rear-end-up step shape, and the front section and the rear section of the circular arc part (5) transit through a conical section (6); the first straight part (3) and the second straight part (4) are respectively located below the circular arc part (5); and the three are connected into a whole in sequence. According to the reinforcing plate for the bumper bar below the vehicle door, the glue applying area is widened through the circular arc part on the Omega-shaped plate body, and the adhesive force between the reinforcing plate and the outside door panel of the vehicle can be increased, so that stability of the mounting clearance between the bumper bar and the outside door panel of the vehicle is guaranteed, and the compression strain resistant intensity of the door panel can be enhanced simultaneously. The reinforcing plate has the characteristics of simple structure, convenience in processing, low cost, good welding positioning and the like. The reinforcing plate is applicable to various vehicles.

Description

technical field [0001] The invention relates to a car door, in particular to a reinforcement plate for an anti-collision bar under a car door. Background technique [0002] With the development of technology, consumers have higher and higher requirements for the collision safety performance of the vehicle. For side collisions, it is difficult to meet the required safety performance requirements with a single cold-formed anti-collision bar. Now, shockproof rubber is often used. Apply directly on the anti-collision bar, but the anti-collision bar has a circular arc surface, the glue is not reliable, and the gap between the anti-collision bar and the outer door panel is unstable. If the gap is too large, the quality will be affected, and even the outer door panel will be deformed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a reinforcement plate for the lower anti-collision bar of a car door to stabilize the ins...
