The invention relates to the technical field of vehicle structures, and discloses a vehicle and a front lower protection device.The front lower protection device comprises a cross rod, a left protection support and a right protection support, the cross rod comprises an outer beam and connecting bases, and the connecting bases are arranged on the left side and the right side of the outer beam correspondingly; the left protection support and the right protection support are both connected with the connecting base, a structure reinforcing support is further arranged in the outer beam, a gap is formed between the structure reinforcing support and the outer beam, and the gap is filled with foaming materials. The structure reinforcing support is arranged in the outer beam of the cross rod, the space between the structure reinforcing support and the outer beam is filled with the foaming material, the structural strength of the cross rod is reinforced through the structure reinforcing support and the foaming material, and therefore the collision performance of the front lower protection device is improved, meanwhile, the structure reinforcing support and the foaming material are small in density, and the cross rod is light in weight. The size of the outer beam does not need to be increased, and arrangement space of other systems is prevented from being affected.
本发明涉及车辆结构技术领域,公开了一种车辆及其前下防护装置,前下防护装置包括横杆、左防护支架和右防护支架,所述横杆包括外梁和连接座,所述外梁的左右两侧分别布置有所述连接座,所述左防护支架和所述右防护支架均与所述连接座连接,所述外梁内还布置有结构增强支架,所述结构增强支架与所述外梁之间具有间隙,所述间隙内填充有发泡材料。在横杆的外梁内布置结构增强支架,结构增强支架与外梁之间填充发泡材料,利用结构增强支架和发泡材料强化横杆的结构强度,从而提高了前下防护装置的碰撞性能,同时结构增强支架和发泡材料的密度小,横杆的重量轻,不需要增加外梁的尺寸,避免影响其他系统的布置空间。
