Electric supporting rod of automobile tail door
According to an electric supporting rod of an automobile tail door, a screw is arranged in a guide pipe, a retractable pipe is arranged in the guide pipe in a sliding fit mode, one end of the retractable pipe is in threaded fit with the screw through a nut, the other end of the retractable pipe is connected with a second hinge seat, the screw is supported in a motor protection sleeve through a bearing, one end of the bearing is axially positioned through a limiting boss arranged on the screw, and the other end of the bearing is axially limited through a friction ring fixedly connected to the screw; the motor protection sleeve is internally provided with a holding mechanism used for preventing the retractable pipe from retracting, the holding mechanism comprises two oppositely-arranged bearing bushes and a force storage spring applying pressure to the bearing bushes, the opposite ends of the two bearing bushes are provided with inferior arc grooves, the inferior arc grooves of the two bearing bushes correspond to the outer circle of the friction ring, the radius of each inferior arc grooves is the same as that of the friction ring, spring installation holes are formed in the opposite ends of the two bearing bushes, one end of the force storage spring is located in the corresponding spring installation holes, the other end of the force storage spring abuts against the motor protection sleeve, the inferior arc grooves of the two bearing bushes are in friction fit with the boss on the screw under the action of the force storage spring.
一种汽车尾门的电动撑杆，导向管内设置一螺杆，一伸缩管滑动配合在导向管中，伸缩管一端通过螺母与螺杆螺纹配合，伸缩管另一端连接第二铰接座，螺杆通过轴承支承在电机保护套中，轴承的一端由螺杆上设置一限位凸台轴定位，另一端由固定连接在螺杆上摩擦圆环轴向限位，电机保护套内设置一用于防止伸缩管回缩的抱紧机构，抱紧机构包括两个相向设置的轴瓦和对轴瓦施加压力的蓄力弹簧，两个轴瓦相向端设有劣弧凹槽，两个轴瓦劣弧凹槽对应摩擦圆环外圆，劣弧凹槽的半径与摩擦圆环的半径相同，两个轴瓦的相反端设有弹簧安装孔，蓄力弹簧一端位于弹簧安装孔中，另一端抵住电机保护套，两个轴瓦的劣弧凹槽在蓄力弹簧的作用下与螺杆上的凸台形成摩擦配合。
