The invention provides an electric tailboard coupling push rod lifting structure, and belongs to the technical field of automobile auxiliary equipment. The driving motor is arranged on the driving lifting push rod and is in power connection with the reduction gearbox of the driving lifting push rod, and meanwhile, the connecting shaft is arranged between the reduction gearbox of the driving lifting push rod and the reduction gearbox of the follow-up lifting push rod and is connected with the reduction gearbox of the driving lifting push rod. The driving motor synchronously drives the driving lifting push rod and the follow-up lifting push rod to act, the structure is simple, wiring and assembling are convenient, synchronous action can be achieved under the condition that a regulation and control system is not configured, and therefore the control difficulty and cost are reduced. Besides, universal couplings are arranged at the two ends of the connecting shaft, universal connection of the driving lifting push rod and the follow-up lifting pull rod is achieved, the problem of position floating in the action process is solved, and therefore the electric push rod is suitable for error situations possibly caused by machining, installation and use, the structural flexibility is higher, and application and popularization of the electric push rod are facilitated.
本发明提供了一种电动尾板联轴推杆举升结构,属于汽车辅助设备技术领域。本发明通过在主动举升推杆上设置驱动电机并与主动举升推杆的减速箱动力连接,同时,于主动举升推杆的减速箱和随动举升推杆的减速箱之间设置有连接轴并相互连接,实现了一台驱动电机同步驱动主动举升推杆和随动举升推杆动作,结构简单,布线装配方便,还能在不配置调控系统的情况下实现同步动作,从而降低了控制难度和成本。另外,通过在连接轴的两端设置有万向联轴器,实现了主动举升推杆和随动举升拖杆的万向连接,满足了动作过程中位置浮动的问题,从而适应因加工、安装以及使用而可能导致的误差情景,结构灵活性更高,利于电动推杆的推广使用。
