The invention discloses a multi-specification vehicle-mounted hydrogen storage cylinder protection device based on negative Poisson's ratio, the protection device adopts multiple energy absorption and shock absorption means to ensure the safety of a vehicle-mounted hydrogen storage cylinder, and the protection device comprises shock absorption devices additionally arranged on the upper and lower sides of the vehicle-mounted hydrogen storage cylinder, foam plates filled on the left and right sides, and a negative Poisson's ratio inner core filled in a protection shell, and the safety of the vehicle-mounted hydrogen storage cylinder is greatly improved through the combination of various damping means. Therefore, the fuel cell vehicle can still run safely after collision, the vehicle-mounted hydrogen storage bottle is prevented from being damaged, and the safety of the fuel cell vehicle is enhanced. And the compression amount of the upper and lower damping devices and the sizes of the foam plates on the left and right sides can be adjusted according to the vehicle-mounted hydrogen storage cylinders of different specifications so as to better adapt to and support the vehicle-mounted hydrogen storage cylinders, and an excellent buffering and energy absorbing effect is provided.

    本发明公开了一种基于负泊松比的多规格车载储氢瓶防护装置,该防护装置采用了多种吸能减震手段来保证车载储氢瓶的安全性,包括车载储氢瓶上下方加装的减震装置、左右侧填充的泡沫板、以及防护壳体内部装填的负泊松比内芯,多种减震手段组合使得车载储氢瓶安全性大幅提高。以使得燃料电池汽车在发生碰撞事件后仍能安全运行,防止车载储氢瓶受损,增强燃料电池汽车安全性。且可以根据不同规格的车载储氢瓶调整上下方减震装置的压缩量和左右两侧的泡沫板尺寸以更好地适应和支撑车载储氢瓶,提供优秀的缓冲吸能效果。
