Trigger type energy absorption structure and long-distance energy absorption guardrail
The invention provides a trigger type energy absorption structure which comprises a trigger piece and an energy absorption assembly. A through cavity and a window are formed in the trigger piece. Theenergy absorption assembly comprises an installation plate, an elastic energy absorption piece and a blocking plate. In the non-triggered state of the trigger type energy absorption structure, the elastic energy absorption piece is contracted in the through cavity, and a second edge of the blocking plate abuts against the inner wall of the trigger piece. In the triggered state of the trigger typeenergy absorption structure, the second edge of the blocking plate is separated from the constraint of the trigger piece, and the elastic energy absorption piece is unfolded and pushes the second edgeof the blocking plate out of the window. The invention further provides a long-distance energy absorption guardrail. According to the trigger type energy absorption structure provided by the invention, the trigger piece is matched with the energy absorption assembly, the blocking plate is released by pushing the trigger piece, the impact force of a foreign object is transmitted to the elastic energy absorption piece through the blocking plate, the kinetic energy of the foreign object is absorbed through the elastic energy absorption piece, and then the foreign object impacting the guardrail finally stops, so that the technical problem that a guardrail can only play a guiding role and is poor in energy absorption effect is effectively solved.
本申请提供了一种触发式吸能结构，包括触发件和吸能组件，触发件上开设有通腔和窗口，吸能组件包括安装板、弹性吸能件和阻拦板，在触发式吸能结构的未触发状态下，弹性吸能件收缩于通腔内，阻拦板的第二边抵接于触发件的内壁上；在触发式吸能结构的触发状态下，阻拦板的第二边脱离触发件的约束，弹性吸能件展开并将阻拦板的第二边推出窗口外；还提供了一种长距离吸能护栏。本申请提供的触发式吸能结构采用了触发件与吸能组件配合，通过推动触发件来释放阻拦板，并且通过阻拦板将外物的撞击力传递给弹性吸能件，再通过弹性吸能件吸收外物的动能，进而使撞击护栏的外物最终停下来，从而有效地解决了护栏仅能起导向作用及吸能效果差的技术问题。
