The utility model provides a combined car rear anti collision beam, which includes a rear anti collision beam body, a energy absorbing box and a fixed plate. The rear anti collision beam consists of a base and a collision block. The base includes a base plate and a side plate which is arranged symmetrically at both ends of the bottom of the floor. The collision block is arranged between the two sides of the plate. The collision block includes the insert block, and the insert is inserted. A fixed block is provided on the outer side of the block, with a strip groove and a bar shaped convex on both sides of the insert block, a groove is provided on the outside of the fixed block, a buffer block and a spring are provided in the groove, and a positioning protruding and a positioning groove are respectively arranged on the inside of the left and right sides of the plate, and the energy absorbing box is uniformly distributed between the base and the fixed plate. The advantage is that the collision block itself passes through the buffer block and spring, which can effectively reduce the impact force and improve the cushioning performance. The collision avoidance blocks are independent individual and are connected by each other to form the collision beam body. When the collision is impacted, a part of the collision avoidance block can be replaced according to the actual situation, not only disassembly and replacement, but also saving maintenance dimension. Repair costs.

一种组合式汽车后防撞梁
本专利技术涉及汽车
,尤其涉及一种组合式汽车后防撞梁。
技术介绍
防撞钢梁是用冷轧钢板冲压而成的U形槽,与车架纵梁连接,作为汽车被动安全的第一道屏障,防撞钢梁是吸收和缓和外界冲击力、防护车身前后部的重要安全装置。目前,现有的后防撞梁的后防撞梁本体大多是一体冲压成型的板状结构,其在被撞击形变后都要整体更换,大大增加了维护维修成本。
技术实现思路
为解决上述问题,本专利技术公开了一种组合式汽车后防撞梁。为了达到以上目的,本专利技术提供如下技术方案:一种组合式汽车后防撞梁,其特征在于:包括后防撞梁本体、吸能盒和固定板,所述后防撞梁本体包括底座和防撞块,所述底座包括底板和对称设置在底板外侧两端的侧板,所述防撞块从左往右依次排列在两侧板之间,所述防撞块包括插接块,所述插接块外侧设有固定块,且插接块左右两侧分别设有条形凹槽和条形凸起,所述固定块外侧向内设有凹槽,所述凹槽内设有缓冲块和弹簧,所述缓冲块外侧呈弧面,所述弹簧两端分别与缓冲块内侧和凹槽底部连接,所述条形凹槽和条形凸起相适配,所述左右两侧板内侧分别设有定位凸起和定位凹槽,所述定位凸起和定位凹槽分别与条形凹槽和条形凸起相适配,所述吸能盒均布在底座和固定板之间。进一步的,所述缓冲块为橡胶缓冲块。进一步的,所述固定块为橡胶固定块。与现有技术相比,本专利技术的有益效果在于:采用了组合式的防撞块来构成整个防撞梁本体,一方面,防撞块自身通过缓冲块和弹簧,可有效减缓冲击力,提高缓冲性能,另一方面,防撞块均为独立个体,通过相互插接构成防撞梁本体,当受到撞击后,可根据实际情况,更换部分防撞块即可,并且由 ...
