External sealing type steel outer pipe electric supporting rod
The invention provides an external sealing type steel outer pipe electric supporting rod. The supporting rod comprises a main body pipe fitting, a vehicle body connector, a guide pipe fitting, a driving motor, a driving lead screw, a supporting pipe fitting, a transmission nut, a door body connector, a cover protection pipe fitting and an auxiliary spring, and is characterized in that a first sealing ring is arranged between the inner wall of the main body pipe fitting and the outer wall of the vehicle body connector. A second sealing ring is arranged between a joint ring edge of the cover protection pipe fitting and a positioning flange of the door body connector, third sealing rings are arranged between the outer wall of the cover protection pipe fitting and the inner wall of the main body pipe fitting, the waterproof performance of the electric supporting rod is improved, the position between the third sealing rings arranged in pairs is filled with lubricating grease, the abrasion loss of the third sealing rings is reduced while the wear parts of the third sealing rings are recovered, the waterproof property is ensured, the second sealing ring is pressed between the positioningflange and the joint ring edge through the auxiliary spring, assembling is easy, a positioning rolling groove and a positioning groove formed in the main body pipe fitting are used for restraining internal parts, extra equipment is not needed in the assembling process, and production is convenient.
本发明提出一种外密封式钢制外管电动撑杆，包括主体管件、车身接头、导向管件、驱动电机、驱动丝杆、支撑管件、传动螺母、门体接头、罩护管件以及辅助弹簧，该电动撑杆在主体管件的内壁与车身接头的外壁之间设置第一密封圈，在罩护管件的接合环边与门体接头的定位法兰之间设置第二密封圈，在罩护管件的外壁与主体管件的内壁之间设置第三密封圈，提升了电动撑杆的防水性能，在成对设置的第三密封圈之间填充润滑油脂，在降低第三密封圈磨损量的同时，弥补其磨损部位，保证防水性能，第二密封圈由辅助弹簧压紧于定位法兰与接合环边之间，装配简单，在主体管件中设置的定位滚槽及定位凹槽用于约束内部零件，装配时不需额外设备，生产方便。
