Energy-absorbing automobile and energy-absorbing mode during collision

Abstract

The invention discloses an energy-absorbing automobile and an energy-absorbing mode during a collision. The energy-absorbing automobile comprises an anti-collision beam, a vehicle body cross beam, a central hinge base fixed to the middle of the vehicle body cross beam, two hydraulic buffers and a first elastic energy-absorbing mechanism, wherein the two hydraulic buffers are symmetrically hinged to the two ends of the central hinge base, and the first elastic energy-absorbing mechanism is fixed in the middle of the central hinge base; and the free end of the first elastic energy-absorbing mechanism abuts against the anti-collision beam. According to the energy-absorbing automobile, a three-stage energy-absorbing effect can be achieved when the automobile collides, the structure is safer, the collision safety requirement is met, the energy-absorbing process does not damage the self structure, repairing or maintenance is not needed after the collision, and the maintenance cost is lower;and the energy-absorbing size of the whole energy-absorbing device is adjustable, different energy-absorbing effects cannot be obtained, and the energy-absorbing device can be adapted to different vehicle types, and the universality is high.

Description

technical field [0001] The invention relates to an energy-absorbable automobile and an energy-absorbing method during collision. Background technique [0002] At present, automobiles are mainly provided with a crush-type energy-absorbing box on the longitudinal beam of the vehicle, and when the vehicle collides longitudinally, the energy-absorbing box itself is collapsed and deformed to absorb the impact energy. However, there are problems of non-maintenance and poor single-stage energy-absorbing effect. At the same time, because the energy-absorbing size of the collapse-type energy-absorbing box is fixed, it needs to be designed separately for vehicles with different body weights, resulting in various specifications and poor versatility. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings, and provide an energy-absorbing automobile and an energy-absorbing method during collision. [0004] To achieve the a...
