Automotive Electromagnetic Active Collision Avoidance Device

Abstract

The invention discloses an electromagnetic active anticollision device for an automobile. The electromagnetic active anticollision device comprises a rigid inner protective frame, an energy absorption mechanism, a crush resisting and damping mechanism, an electromagnetic field safety shielding cover and a rigid outer protective frame. The energy absorption mechanism is a push-pull mechanism mainly composed of a plurality of electromagnets and a telescopic connecting piece, the crush resisting and damping mechanism is mainly composed of electromagnets, the energy absorption mechanism and the crush resisting and damping mechanism are connected to the rigid inner protective frame and use the rigid inner protective frame as a supporting point, and the shielding cover and the rigid outer protective frame cover the energy absorption mechanism and the crush resisting and damping mechanism in sequence so as to provide the electromagnetic field shielding function and the rigid anticollision function respectively. The strong and effective energy absorption and crush resisting and damping structure is constructed through a special electromagnet pole layout mainly based on the principle of homopolar repulsion and heteropole attraction of the electromagnets, strong impact force generated by the collision of the automobile is offset to the maximum limit, head-on collisions and rear-end accidents of the automobile are prevented or reduced, and the degree of secondary damage is effectively lowered.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an automobile electromagnetic active anti-collision device. Background technique [0002] Under the situation that automobile manufacturing technology is becoming more and more mature, with the continuous improvement of people's living standards, the safety requirements for automobiles are also getting higher and higher. The competition in the automobile market will no longer be the competition of automobile manufacturing itself, but In the comprehensive competition in the field of automobile safety, for automobile manufacturers, how to make automobiles safer is the key to winning the competition. [0003] The existing common safety design of automobiles can be divided into two parts: active safety design and passive safety design. [0004] Among them, the passive safety design mainly starts from the following three aspects: first, the car uses a specially designed bod...

Problems solved by technology

However, because most of the former only utilize the hardness of rigid materials or the energy-absorbing properties of elastic materials to alleviate the impact of the collision, the energy-absorbing effect provided by it is very limited and the effect is not good. Major damage; the latter usually uses intelligent control technology to issue an alarm or brake in advance, which has no direct protective effect on the car, and cannot play any anti-collision effect when the system fails or the brake fails
