The utility model provides a new type of rear collision avoidance Liang Zongcheng, including the rear anti collision beam body. The rear anti collision beam body consists of the rear guard beam outer plate, the rear anti collision beam inner plate and the support block which are arranged from outside to inside. The inside ends of the rear plate of the rear collision prevention beam are respectively provided with a energy absorption box, and the hollow structure inside the rear plate against the beam is arranged in the hollow structure. The elastic plate is arranged in the rear edge of the rear anti-collision beam, and the space inside the inner plate of the rear anti-collision beam is filled with a buffer inner lining, and a buffer layer is arranged between the supporting block and the rear anti-collision beam inner plate. The advantages are as follows: the impact resistance and buffer performance of the rear plate are effectively improved by using the internal plate of the rear collision prevention beam and the cushioning inner lining, and the cushioning property can be improved by the arc surface and the buffer layer on the outside of the support block, and the cushioning property of the whole rear anti collision beam is improved by using the cushion plate, and the rear guard is used as a rear guard. When the middle part of the impact plate is impacted, the supporting columns at both ends can provide supporting force to slow down the deformation of the outer plate of the collision prevention beam and improve the impact resistance of the rear impact beam outer plate.

一种新型汽车后防撞梁总成
本专利技术涉及汽车
,尤其涉及一种新型汽车后防撞梁总成。
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,现有的后防撞梁大多都是一个防撞后板配合两个吸能盒的结构,其抗撞性能低,撞击后的前后车辆的车尾和车头都会严重变形。
技术实现思路
为解决上述问题,本专利技术公开了一种新型汽车后防撞梁总成。为了达到以上目的,本专利技术提供如下技术方案:一种新型汽车后防撞梁总成,其特征在于:包括后防撞梁本体,所述后防撞梁本体包括由外至内依次设置的后防撞梁外板、后防撞梁内板和支撑块,所述后防撞梁外板呈中部向外凸起的弧形板状,后防撞梁外板的内侧两端分别设有吸能盒,所述后防撞梁内板和支撑块均设置在两吸能盒之间,所述后防撞梁内板呈与后防撞梁外板相适配的中空弧形板状,其外侧与后防撞梁外板内侧紧贴,内部中空结构中从左往右依次排列有中部向内凹陷的弧形弹性板,且后防撞梁内板内除弧形弹性板之外的空间填充有缓冲内衬,所述支撑块的外侧为与后防撞梁内板内侧面相适配的弧形面,且支撑块与后防撞梁内板间设有缓冲层。进一步的,还包括缓冲垫板,所述支撑块和吸能盒均设置在缓冲垫板上。进一步的,所述缓冲垫板的左右两端还设有对称的限位柱。进一步的,所述限位柱的一端与缓冲垫板固定连接,另一端嵌套于后防撞梁外板内部。与现有技术相比,本专利技术的有益效果在于:采用后防撞梁内板,通过其内部从左往右均匀排列的弧形弹性板可较好的承受来自于后防撞梁外板的冲击力,并结合缓冲内衬,有效提高后 ...
