Abstract

The invention provides a composite energy absorption device for collision. The composite energy absorption device comprises an extruding part and a bursting part, wherein an accommodating cavity and fiber layers stacked on the side wall of the accommodating cavity are arranged in the bursting part; the accommodating cavity is filled with an energy absorption material; the fiber layers is divided into a silk fiber layer arranged on the inner layer and multiple carbon fiber layers stacked on the outer side of the silk fiber layer; the fiber arrangement angles in the carbon fiber layers are different; the extruding part comprises an extruding rod and an extruding plate; the extruding rod and the accommodating cavity are in interference fit, when the extending rod receives external force, one end of the extruding rod extends into the accommodating cavity and extrudes the energy absorption material, and the other end of the extruding rod is connected with the extruding plate.

Description

technical field [0001] The invention relates to an energy-absorbing device, in particular to a collision composite energy-absorbing device which comprehensively utilizes longitudinal compression energy-absorption, transverse extrusion energy-absorption, bursting energy-absorption and tearing energy-absorption. Background technique [0002] With the frequent occurrence of traffic accidents, people pay more and more attention to the safety of automobile collisions. A good energy-absorbing device can protect the safety of occupants in automobile collision accidents, save people's lives, and reduce the degree of injury of people in accidents. Therefore, the design technology of the energy-absorbing structure of the vehicle body has become the key technology of the current automobile safety design. [0003] At present, the energy-absorbing structure of most automobile bodies is still composed of thin-walled pipes. In the event of a collision, the traditional energy-absorbing meth...
