Automobile electric tail door supporting rod
The invention relates to the technical field of automobile tail door supporting rods, in particular to an automobile electric tail door supporting rod. The gas spring comprises an outer sleeve, an inner sleeve and a gas spring body, the inner sleeve can stretch out and draw back relative to the outer sleeve, the gas spring body comprises a cylinder barrel and a piston rod, external threads are arranged on the peripheral face of the piston rod, the cylinder barrel is detachably and fixedly connected with a transmission connecting piece, and an internal threaded hole is formed in the transmission connecting piece. One end of the cylinder barrel is in sealed sliding connection with the piston end of the piston rod, the other end of the cylinder barrel is in sealed fixed connection with the end, close to the first fixing head, of the outer sleeve, a driving device is arranged in the inner sleeve, and the transmission connecting piece is provided with an oil adding mechanism capable of automatically adding lubricating oil into an inner threaded hole in the transmission connecting piece in the shrinkage process of the supporting rod. After the prior art is improved, lubricating oil is automatically supplemented once after the automobile tail door is opened and closed each time through the oil adding mechanism, abrasion in the thread transmission process between the piston rod and the transmission connecting piece is reduced, and therefore the service life is prolonged.
本发明涉及汽车尾门撑杆技术领域，尤其涉及一种汽车电动尾门撑杆；它包括由外套管、内套管及气弹簧，内套管可相对外套管伸缩，气弹簧包括缸筒及活塞杆，活塞杆的外周面上设有外螺纹，缸筒可拆卸的固定连接有传动连接件，传动连接件上设有内螺纹孔，缸筒的一端与活塞杆的活塞端密封滑动连接、另一端与外套管靠近第一固定头的端部密封固定连接，内套管内设有驱动装置，传动连接件上设有在撑杆收缩过程中能够自动添加润滑油到传动连接件上内螺纹孔内的添油机构；本发明对现有技术改进后，通过添油机构在每次开关汽车尾门后自动补充润滑油一次，减少活塞杆与传动连接件之间螺纹传动过程的磨损，从而延长使用寿命。
