Problems solved by technology

It can be seen that the energy-absorbing box cannot be repaired after being squeezed and deformed, and can only be replaced with a new energy-absorbing box. Not only the maintenance cost is high, but also the waste of resources is caused

Abstract

The invention provides an energy absorption box and a vehicle with the same. The energy absorption box comprises a cylinder body with an opening in one end, an end cover which covers the opening end of the cylinder body, a piston, a piston rod, a sleeve and a valve body. The sleeve is fixedly connected to the end cover, and a partition piece is arranged in the sleeve. The partition piece divides the inside of the sleeve into a first space and a second space. A connecting hole is formed in the partition piece, and the first space and the second space are communicated through the connecting hole. The piston is arranged in the sleeve in a sliding mode, and is arranged between the partition piece and the end cover. The piston rod penetrates through the end cover and is connected with the piston. The valve body is arranged in the sleeve, and is used for being matched with the connecting hole to seal the connecting hole when the piston moves towards the cylinder bottom of the cylinder body. The energy absorption box can restore to be in the original shape by simply stretching the piston rod when being collided by the outside, and has the advantages of being simple in operation process, capable of being recycled and capable of greatly saving resources.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular, to an energy-absorbing box and a vehicle with the energy-absorbing box. Background technique [0002] There is an anti-collision beam inside the bumper of the vehicle, and an energy-absorbing box is generally arranged between the anti-collision beam and the longitudinal beam of the vehicle body. When the bumper is hit by an external collision, the energy-absorbing box can absorb part of the energy generated during the collision, reducing Damage to the vehicle caused by the collision and injuries to occupants of the vehicle. At present, the commonly used energy-absorbing box is a hollow square structure. When the bumper is bumped, the bumper is deformed, and the energy-absorbing box is also squeezed, deforming the energy-absorbing box and absorbing the energy generated by the collision. It can be seen that the energy-absorbing box cannot be repaired after being squeezed and deform...
