Electric push rod applied to automobile tailboard
The invention relates to the technical field of automobile tailboards, and discloses an electric push rod applied to an automobile tailboard, the electric push rod comprises an outer pipe and an inner pipe, the outer pipe is provided with a reduction gearbox shell, the reduction gearbox shell is connected with a motor through a planetary reducer, the periphery of a large shaft sleeve is sleeved with a first thrust bearing, and the periphery of a small shaft sleeve is sleeved with a second thrust bearing; wear-resistant sleeves are embedded in the two sides of the reduction gearbox shell correspondingly, and a first travel switch, a second travel switch and a third travel switch which are used for sensing the moving position of the inner pipe are fixedly connected to the inner side wall of the outer pipe from top to bottom correspondingly. The size of a reduction gearbox shell is reduced by adopting the installation arrangement of a planetary reducer and a motor, and the length of an inner pipe is reduced by differentially selecting a first thrust bearing and a second thrust bearing for bearing thrust of the inner pipe and a third deep groove ball bearing for bearing tension. And a plurality of travel switches are used for controlling, so that a dual-protection function of electronic limiting at a limit position can be achieved.
本发明涉及汽车尾板的技术领域，公开了运用于汽车尾板的电动推杆，包括外管以及内管，外管上安装有减速箱壳，减速箱壳与电机之间通过行星减速机连接，大轴套的外周上套设有第一推力轴承，小轴套的外周上套设有第二推力轴承，减速箱壳的两侧上分别嵌入有耐磨套，沿着外管的内侧壁自上而下分别固定连接有感应内管移动位置的第一行程开关、第二行程开关、第三行程开关，通过将耐磨套设置于减速箱壳的两侧上减来小安装距，通过采用行星减速机与电机的安装布置来减小减速箱壳的体积，通过内管承受推力的第一推力轴承和第二推力轴承以及与承受拉力的第三深沟球轴区别选择来减小内管长度，利用多个行程开关控制可以起到极限位置电子限位的双重保护功能。
