The sealing assembly comprises an output shaft, the output shaft is used for driving an automobile windscreen wiper arm to swing in a reciprocating mode, a water conveying pipe is arranged in a shaft hole of the output shaft, one end of the water conveying pipe extends out of the output shaft, a check ring is arranged at the other end of the water conveying pipe, and the check ring comprises a limiting shaft section and a flange shaft section. The limiting shaft section is in interference fit with the shaft hole of the water conveying pipe, the shaft end face, close to one side of the water conveying pipe, of the flange shaft section abuts against the shaft end face of the water conveying pipe, and the check rings connect and fix the limiting shaft section and the hole wall of the shaft hole of the water conveying pipe and the shaft end face of the flange shaft section and the shaft end face of the water conveying pipe through ultrasonic welding. A water spraying rod is inserted into the shaft hole of the water conveying pipe through an inner hole of the check ring, the water spraying rod is in sliding fit with the inner hole of the check ring, a sealing ring is arranged between the water spraying rod and the water conveying pipe, and the inner circle of the sealing ring is in interference fit with the water spraying rod to form sealing. And the sealing ring is positioned between the stepped surface of the stepped hole and the limiting shaft section of the check ring.
本发明涉及一种雨刮电机的密封组件,包括输出轴,输出轴用于驱动汽车雨刮臂往复摆动,输出轴的轴孔内设有一输水管,输水管的一端延伸出输出轴,输水管的另一端设有一挡圈,挡圈包括限位轴段、凸缘轴段,限位轴段过盈配合在输水管的轴孔中,凸缘轴段靠近输水管一侧的轴端面相抵于输水管的轴端面,挡圈通过超声波焊将限位轴段与输水管的轴孔孔壁之间,以及凸缘轴段的轴端面与输水管的轴端面之间连接固定,一喷水杆经挡圈的内孔插入输水管的轴孔中,喷水杆与挡圈的内孔滑动配合,喷水杆与输水管之间设置密封圈,密封圈的内圆与喷水杆之间过盈配合形成密封,输水管的轴孔为阶梯孔,密封圈位于所述阶梯孔的台阶面与所述挡圈的限位轴段之间。
