Automobile body collision energy absorption structure of hydrogen energy automobile

Abstract

The invention provides an automobile body collision energy absorption structure of a hydrogen energy automobile. The structure comprises an underframe and two front longitudinal beams. Each front longitudinal beam comprises an energy absorption box, a front longitudinal beam middle section and a front longitudinal beam rear section which are connected in sequence; the rear ends of the two front longitudinal beams are connected to the underframe; an anti-collision beam is connected in front of the two front longitudinal beams; two ends of the anti-collision beam are fixed on the two energy absorption boxes; and a plurality of collapse induction grooves are formed in the two energy absorption boxes and the middle sections of the two front longitudinal beams. The automobile body collision energy absorption structure of the hydrogen energy automobile has the beneficial effects that the energy absorption boxes of the two front longitudinal beams and the middle sections of the two front longitudinal beams are provided with the collapse induction grooves so that an impact force generated during automobile collision can be partially absorbed in a compression mode; and the rear section of the front longitudinal beam can transmit the residual impact force to the underframe so that a passenger compartment is deformed as little as possible, and safety of automobile passengers during automobile collision is guaranteed.

Description

technical field [0001] The invention relates to the field of hydrogen energy vehicles, in particular to a body collision energy absorbing structure of a hydrogen energy vehicle. Background technique [0002] When a car collides (especially the front of the car), it often produces a huge collision impact force. For hydrogen energy vehicles, the collision impact force will crush the front structure of the car, resulting in the intrusion of rigid structures such as electric stacks in the front cabin of the car. The passenger compartment, therefore, the collision of a hydrogen energy vehicle will often cause great damage to the occupants in the vehicle. At the same time, a collision of a hydrogen energy vehicle will easily squeeze the hydrogen cylinder at the bottom of the hydrogen energy vehicle, resulting in hydrogen leakage or even explosion. In order to reduce the damage to occupants in the collision of hydrogen energy vehicles and the hazards of hydrogen leakage, it is nece...
