Active protection device

Abstract

Provided is an active protection device, pertaining to the technical field of car safety.The active protection device is characterized in that an anti-collision beam is divided into a fixed beam and a movable beam; the movable beam is installed on the fixed beam and can perform horizontal movement by stretching and retracting relative to the fixed beam; a retractable locking device of the movable beam is arranged on the fixed beam and can be used for locking the retraction state of the movable beam; a stretching driving unit of the movable beam is arranged on the fixed beam and used for driving the movable beam to stretch outwardly; a stretching locking device of the movable beam is arranged on the fixed beam; a spring buffer device is arranged between the fixed beam and the movable beam; the movable beam is capable of outwardly stretching and locking to receive collision; a spring protection device is opened to buffer collision; and a distance measurement device is arranged on a car and connected with a computer which is also connected with retractable locking device of the movable beam.The active protection device has following advantages: without increasing total length of the car and buffering impact force, larger physical collision space is obtained.

Description

technical field [0001] The invention belongs to a field of automobile safety technology, in particular to an automobile anti-collision protection device. Background technique [0002] Nowadays, there are more and more cars on the road, and traffic accidents are 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 ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned patent solves the defects of the collision impact force and the use of air cushion protection in the prior art. However, this patent is not perfect. Although the elongated movable beam can bring a certain buffer space to the car, the impact force is very large. Yes, so the impact on the passengers at the moment of collision is enough to cause significant injury

Therefore, the efforts of the existing technology in this area are not satisfactory, and there is still a lot of room for improvement
