The movable step structure comprises an upper fixing support, a universal support, a lower fixing support, springs and pin shafts, the upper fixing support and the universal support are connected into a chain type structure through the springs, and the universal support and the lower fixing support are connected into a chain type structure through the pin shafts; the upper portion of the upper fixing support is connected with the connecting plate through a fourth pin shaft, and the lower portion of the lower fixing support is connected with the pedal through a third pin shaft. When the vehicle runs normally and is collided, under the combined action of the pin shafts and the springs, all the chain type structures can rotate in the front-back direction, namely, the movable stepping anti-collision structures swing left and right, and then the movable stepping structures are lifted and prevented from being collided. The stepping structure can be prevented from being collided by obstacles, the stability of the structure is improved, the height of the stepping structure can be freely adjusted by adjusting the number of the universal supports so as to achieve a more reasonable using effect, and the stepping structure is reasonable in structure and safe and convenient to use.
本发明公开了一种重型载货车活动踏步结构,包括上固定支架、通用支架、下固定支架、弹簧以及销轴,所述上固定支架与通用支架、通用支架与下固定支架分别通过弹簧和销轴连接为链式结构;上固定支架的上部通过销轴四与连接板连接,下固定支架的下部通过销轴三与踏板连接;当车正常行驶遇到磕碰时,在各自销轴和弹簧的共同作用下,各个链式结构会在前后方向上转动,即活动踏步防撞结构左右摆动,进而活动踏步结构被抬高,防止撞坏。本发明可防止障碍物对踏步结构的碰撞,提高了结构的稳定性,通过通用支架个数的调整可实现踏步结构高度的自由调节,以达到更合理的使用效果,结构合理,使用安全、方便。
