Beam type active anti-collision device

Abstract

Provided is a beam type active anti-collision device which belongs to the field of automobile safety technology. For allowing an automobile to have a better anti-collision property, the following technical scheme is utilized: an anti-collision beam is divided into a fixed beam and a movable beam; the movable beam is installed on the fixed beam. The movable beam is able to extend out and retreat back horizontally with respect to the fixed beam. A movable beam retraction locking device is installed on the fixed beam. The movable beam retraction locking device is able to lock the movable beam in the retraction status. The fixed beam is provided with a movable beam extension drive device for driving the movable beam to extend out. The fixed beam is further provided with a movable beam extension locking device. The movable beam extension locking device is able to lock the movable beam in the extension status. The movable beam can be extended and locked for absorbing the collision. A range unit is installed on the automobile. The range unit is connected with a computer. The computer is connected with the movable beam retraction locking device. The beam type active anti-collision device has the advantage of obtaining a larger physical collision space without increasing the total length of the automobile.

Description

technical field [0001] The invention belongs to a field of automobile safety technology. Background technique [0002] There are more and more cars on the road, and traffic accidents are becoming more and more frequent. When the car is running at high speed, due to the inertial effect of the material, the car and its passengers have stored a huge amount of inertial energy. In case of a frontal collision of the car at this time, these energies are released instantly, which will produce a huge impact force, and the consequences are unimaginable. Because when the car collides head-on, the speed of the car decreases instantly, and even returns to a static state. During this process, the passengers in the car will have to bear a huge forward impact force, and may be injured as a result. In the prior art, anti-collision steel beams and low-speed crash boxes are installed at the front and rear of the longitudinal beams of the vehicle frame in order to alleviate the impact force ...

AI Technical Summary

Problems solved by technology

But this technical solution also has its disadvantages, that is, there must be an anti-collision space between the carriage and the frame.

This will increase the overall length of the car and affect the flexibility of the car

[0004] It can be seen that the efforts of the existing technology in this area are not satisfactory, and there is still a lot of room for improvement
