A car door anti-collision device with high safety

Abstract

The present invention proposes a car door anti-collision device with high safety, the front joint of the anti-collision plate, the main body of the anti-collision plate and the rear joint of the anti-collision plate; the front joint of the anti-collision plate and the rear joint of the anti-collision plate are respectively fixedly installed Both ends; the anti-collision plate body includes a rectangular bottom plate, a V-shaped middle plate and an arc-shaped outer plate; the V-shaped middle plate is located on one side of the rectangular bottom plate and the two ends of the V-shaped middle plate are fixedly connected to the two ends of the rectangular bottom plate, and the V-shaped middle plate A triangular through hole is formed between the plate and the rectangular bottom plate; the arc-shaped outer plate is located on the side of the V-shaped middle plate away from the rectangular bottom plate and the two ends of the arc-shaped outer plate are fixedly connected with the two ends of the V-shaped middle plate; the rectangular bottom plate and the V-shaped middle plate The thickness of the plate and the curved outer plate are the same. The invention can effectively improve the safety of both sides of the car, and has little influence on the weight of the car door.

Description

Technical field [0001] The present invention relates to the technical field of automobile parts, and in particular to a vehicle door anti-collision device with high safety. Background technique [0002] The front and rear direction of the car is more likely to cause collisions. 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 the protection measures are less , And the buffer distance is short, the front and rear directions of the car corresponding to the collision on both sides of the car are more dangerous. [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. It improves the safety performa...

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
