Abstract

The invention is suitable for the technical field of passive safety protection devices, and provides a combined energy absorber. The combined energy absorber comprises a collision baffle, a flanged pipe, a base and an energy absorption assembly, wherein one end of the flanged pipe is fixedly connected with the collision baffle, and a plurality of cutting grooves are formed in the pipe wall of theflanged pipe in the axis direction of the flanged pipe; the other end of the flanged pipe abuts against the base, and the side, which is away from the flanged pipe, of the base is used for being connected with a vehicle body; and the energy absorption assembly is arranged in the flanged pipe and fixedly connected with the collision baffle. According to the forming die, the base abuts against the other end of the flanged pipe, and the plurality of cutting grooves are formed in the pipe wall of the flanged pipe in the axis direction of the flanged pipe, so that the flanged pipe can crack, overturn, curl and absorb energy under the constraint of the base in the collision process. Meanwhile, the energy absorption assembly is arranged in the flanged pipe, so that the base can compress the energy absorption assembly to absorb energy in the operation process, and the overall energy absorption capacity of the energy absorber is improved.

Description

technical field [0001] The invention relates to the technical field of passive safety protection devices, and more specifically relates to a combined energy absorber. Background technique [0002] With the rapid development of science and technology, the transportation industry represented by high-speed rail trains has made unprecedented progress, thus providing great convenience for people's travel and life. The frequency of accidents has also increased significantly, so some protective measures need to be taken. [0003] Traffic vehicle operation safety protection is divided into active safety protection and passive safety protection. Active safety protection mainly refers to the various protective measures adopted before traffic accidents during normal train operation, such as regular inspection of roads, use of various driving signs, use of traffic lights, and use of traffic police command and so on. Passive safety protection means that when a traffic accident occurs, ...
