The invention relates to a flat-head truck bumper capable of absorbing impact kinetic energy, which belongs to the field of automobile accessories, and is characterized in that a plurality of disc-shaped rubber buffer airbags are transversely arranged in front of a rectangular frame side by side, and a bumper made of rectangular high-density resin and a steel wire mesh is arranged in front of the buffer airbags; a cuboid-shaped cab is arranged above the front surface of the frame; a groove is transversely and vertically formed in the middle of the front portion of a cab, a plurality of rectangular buffering air cushions are transversely and vertically installed in the groove, and a rectangular middle net made of resin materials is installed in front of the buffering air cushions. The lower portion of each buffering air cushion is connected with the upper portion of the corresponding buffering air bag below through a cylindrical rubber pipeline, and the interiors of the buffering air cushions are communicated. When the bumper of the flattop truck is impacted, the bumper extrudes the rear buffer air bag backwards instantly, and the buffer air bag starts to be compressed quickly and absorbs kinetic energy to release internal air to the buffer air cushion from the rubber pipeline.
本发明一种可吸收撞击动能的平头卡车保险杠属于汽车附件领域,在长方形车架的前方横向并排安装多个圆盘状的橡胶缓冲气囊,在缓冲气囊的前面安装长方形的高密度树脂外加钢丝网制成的保险杠,在车架前面的上方安装长方体形状的驾驶室,在驾驶室正前方的中部横向垂直设置了凹槽、在凹槽的里面横向垂直安装了多个长方形的缓冲气垫、在缓冲气垫的前方安装了长方形的树脂材料的中网、每个缓冲气垫的下方通过一根圆柱形的橡胶管道与下方对应的缓冲气囊的上方连接并且内部相通,当平头卡车的保险杠受到撞击时保险杠瞬间向后挤压后方的缓冲气囊、缓冲气囊开始快速压缩并且吸收动能将内部的气体从橡胶管道释放给缓冲气垫。
