The invention relates to a lightweight commercial vehicle rear protection device and a commercial vehicle, and belongs to the field of commercial vehicle parts, the rear protection device comprises a rear protection cross rod and a support, the support comprises a connecting piece connected with the support, and the connecting piece is bonded with the rear protection cross rod. The support and the rear protective cross beam are connected through the connecting piece, the cross sectional area of the connecting piece is large, and therefore compared with the mode that the support and the rear protective cross beam are directly bonded, the mode that the support and the rear protective cross beam are bonded through the connecting piece is firmer. The rear protection transverse rod is made of a composite material composed of long glass fibers and polyurethane resin, the weight reduction effect is remarkable, the rear protection transverse rod and the connecting piece are bonded through the structural adhesive, the weight of an additional connecting part does not need to be increased, and the purpose of light weight is achieved while the structural integrity is guaranteed. The rear protection device is easy and convenient to install, light weight of the rear protection device of the commercial vehicle is achieved, cost is low, and the conditions of large-scale production and use can be met.
本申请涉及一种轻量化的商用车后防护装置及商用车,属于商用车零部件领域,其中该后防护装置包括:后防护横杆和支架,所述支架包括与支架连接的连接件,连接件与后防护横杆粘接。使用连接件对支架和后防护横梁进行连接,连接件的横截面积较大,因而与支架和后防护横梁直接相粘接相比,采用连接件与后防护横梁相粘接的方式会更为牢固。后防护横杆由长玻璃纤维和聚氨酯树脂组成的复合材料制成,降重效果显著,而使用结构胶对后防护横杆和连接件进行粘接,不用增加额外的连接部件的重量,在保证结构完整性的同时,达到轻量化的目的。本申请的后防护装置安装工序简便,实现了商用车后防护装置的轻量化,且成本不高,能够满足大规模生产使用的条件。
