The pressure relief type automobile bumper comprises a shell, a first buffering material, a connecting piece, a second buffering material, a reinforcing cross beam, a crumple longitudinal beam and a front longitudinal beam, the first buffering material is fixedly installed on the inner side of the shell, the second buffering material is arranged on the inner side of the first buffering material, and the reinforcing cross beam is fixedly installed on the inner side of the second buffering material. The first buffer material and the second buffer material are connected through a connecting piece; the rack is fixedly mounted on the outer side of the second buffer material; and the cavity is formed in the inner side of the second buffering material, stirring blades are arranged on the inner side of the cavity, and the two ends of the second buffering material are connected with air conveying pipes. According to the pressure relief type automobile bumper capable of avoiding secondary damage, multi-stage buffering pressure relief can be conducted, offset impact force can be evenly dispersed, so that impact damage is reduced, meanwhile, a large amount of carbon dioxide gas can be generated in the impact process and conveyed to a cabin, and secondary damage to a driver due to the fact that the cabin is on fire is avoided.

    本发明公开了一种避免二次伤害的泄压型汽车保险杆,包括壳体、第一缓冲料、连接件、第二缓冲料、加强横梁、溃缩纵梁和前纵梁,所述壳体的内侧固定安装有第一缓冲料,且所述第一缓冲料的内侧设置有第二缓冲料,并且所述第一缓冲料和第二缓冲料两者之间通过连接件连接;还包括:齿条,固定安装于第二缓冲料的外侧;空腔,开设于第二缓冲料的内侧,所述空腔的内侧设置有搅动片,所述第二缓冲料的两端连接有输气管。该避免二次伤害的泄压型汽车保险杆可以进行多级缓冲泄压,且可以对偏置撞击力进行匀散,从而减小撞击伤害,同时可以在撞击过程中产生大量二氧化碳气体并输送至机舱,避免机舱起火而对驾驶者造成二次伤害。
