The invention provides a semitrailer and a rear bumper thereof. The rear bumper comprises two stand columns, a cross beam, two connecting pieces and two locking mechanisms. The two stand columns are transversely spaced in parallel and used for being connected with the rear end of the semitrailer. The cross beam and the stand columns are longitudinally arranged at intervals; the cross beam extendsalong the transverse direction; the two connecting pieces are correspondingly arranged between the stand column and the cross beam. Each connecting piece comprises a first connecting arm and a secondconnecting arm; the middle of the first connecting arm in the length direction is hinged to the first end of the second connecting arm, the first end of the first connecting arm is hinged to the standcolumn, the second end of the second connecting arm is hinged to the cross beam, and the second end of the first connecting arm moves in the length direction of the cross beam so that the distance between the cross beam and the stand column can be adjusted. The locking mechanism is arranged corresponding to the connecting piece; each locking mechanism locks the connecting piece and the cross beamso as to keep the distance between the cross beam and the stand column. Therefore, the distance between the rear end face of the rear bumper and the rear end face of the container is adjustable, andthe requirements of relevant laws and regulations can be met.
本发明提供了一种半挂车及其后保险杠。后保险杠包括两立柱、横梁、两连接件及两锁止机构。两立柱沿横向平行间隔,用于连接半挂车的后端;横梁与立柱沿纵向间隔设置;横梁沿横向延伸;两连接件对应设置于立柱与横梁之间;各连接件均包括第一连接臂和第二连接臂,第一连接臂长度方向的中部与第二连接臂的第一端铰接连接,第一连接臂的第一端与立柱铰接连接,第二连接臂的第二端与横梁铰接连接,第一连接臂的第二端沿横梁的长度方向移动,以使横梁与立柱之间的距离可调;锁止机构对应连接件设置;各锁止机构锁止连接件和横梁,以保持横梁与立柱之间的距离。因此,该后保险杠的后端面与集装箱的后端面之间的距离可调,从而能够满足相关法规的要求。
