Adjustable car crash energy absorption device

Abstract

The invention discloses an adjustable car crash energy absorbing device. The adjustable car crash energy absorbing device comprises an anti-corrosion beam, a car body cross beam, a center hinged seat,hydraulic dampers and a first elastic energy absorbing mechanism. The output ends of the two hydraulic dampers are fixedly connected with adjusting connecting rod assemblies correspondingly. The other ends of the two adjusting connecting rod assemblies are both fixedly connected with lower sliding blocks. The two lower sliding blocks are symmetric about the center hinged seat. The two lower sliding blocks are slidably connected to the car body cross beam. First friction plates are fixed to the bottom surfaces of the lower sliding blocks. Second friction plates are fixed to the positions, corresponding to the first friction plates, of the car body cross beam. A hinge support and a second elastic energy absorbing mechanism are fixed to each lower sliding block. A supporting arm is hinged toeach hinge support. The other ends of the supporting arms are fixedly hinged to the anti-corrosion beam. The free end of each second elastic energy absorbing mechanism is fixed to an upper sliding block. The upper sliding blocks are slidably connected to the anti-corrosion beam. The adjustable car crash energy absorbing device can achieve the three-grade energy absorbing effect, does not damage the self-structure in the energy absorbing process and is lower in maintenance cost, applicable to different car types and high in universality.

Description

technical field [0001] The invention relates to an adjustable automobile collision energy-absorbing device. 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 adjustable automobile collision energy-absorbing device. [0004] To achieve the above object, the specific scheme of the p...
