Car door anti-collision device with high safety

Abstract

The invention provides a car door anti-collision device with high safety. The car door anti-collision device comprises an anti-collision plate front joint, an anti-collision plate body and an anti-collision plate rear joint, wherein the anti-collision plate front joint and the anti-collision plate rear joint are fixedly mounted at the two ends of the anti-collision plate body respectively; the anti-collision plate body comprises a rectangular bottom plate, a V-shaped intermediate plate and a curved shell plate; the V-shaped intermediate plate is positioned on one side of the rectangular bottom plate, and the two ends of the V-shaped intermediate plate are fixedly connected with the two ends of the rectangular bottom plate; a triangular through hole is formed between the V-shaped intermediate plate and the rectangular bottom plate; the curved shell plate is positioned on one side, far away from the rectangular bottom plate, of the V-shaped intermediate plate, and the two ends of the curved shell plate are fixedly connected with the two ends of the V-shaped intermediate plate; the rectangular bottom plate, the V-shaped intermediate plate and the curved shell plate are the same on thickness. The car door anti-collision device can effectively improve the safety of the two sides of a car and has little influence on the weight of a car door.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a car door anti-collision device with high safety. Background technique [0002] The possibility of collision in the front and rear directions of the car is relatively high. At present, the key safety protection measures of the car are also concentrated in the front and rear directions of the car, such as front and rear anti-collision beams and airbags. Compared with the two sides of the car, not only are there fewer protective measures , and the buffer distance is shorter, and the front and rear directions of the car are more dangerous when collisions occur on both sides of the car. [0003] The anti-collision bar of the car door is the most important protection device on both sides of the car. The most basic form of the anti-collision bar of the car door is a high-strength steel plate structure type and a high-strength steel pipe structure type, which improves the safety per...

AI Technical Summary

Problems solved by technology

The car door anti-collision bar is fixedly installed on the inner panel of the car door, but the safety performance of the current car anti-collision bar is low, and the ability to protect the safety of the people in the car is poor
