According to the push rod device, the telescopic plate of the push rod device and the vehicle with the telescopic plate, the spiral arm is indirectly connected with the telescopic support and the push rod, the pushing force or pulling force of the telescopic support, the push rod and even foreign objects to be stretched out or retracted to the driving assembly can be greatly reduced, and it is avoided that the driving assembly is damaged under the action of external force of the pushing force or pulling force; the service life of the driving assembly can be greatly prolonged, and the replacement frequency and the use cost of parts are reduced; the distance from the connecting point of the rotating arm and the driving assembly to the rotating point is smaller than the distance from the connecting point of the rotating arm and the telescopic support to the rotating point, the lever amplification effect is formed, the telescopic support has the telescopic effect, and the telescopic amplification effect is formed under the rotating effect of the rotating arm. The push rod can be driven to do large-stroke action, the performance requirement and the use cost of the driving assembly can be reduced to a great extent, and the working efficiency of the driving assembly is greatly improved.

    本发明涉及推杆装置及其可伸缩板和带可伸缩板的车,通过旋臂与伸缩支架和推杆间接连接,能大大减小伸缩支架和推杆,甚至待伸出或缩回的外物对驱动组件的推力或拉力,避免其在推力或拉力的外力作用下受损,能大大延长驱动组件的使用寿命,减少零部件更换频率和使用成本;旋臂与驱动组件的连接点到转动点的距离,比旋臂与伸缩支架的连接点到转动点的距离小,形成杠杆放大效应+伸缩支架具有伸缩作用,在旋臂的转动作用下,形成伸缩放大效应——该二级放大结构,使得驱动组件的较小行程,能带动推杆做出较大行程动作,能够很大程度上降低驱动组件的性能要求和使用成本,大大提高其工作效率。
