The invention relates to an electric stepless regulation long slide rail for a passenger car, which belongs to the field of automobile seat slide rails and comprises an upper slide rail assembly and a lower slide rail. The upper sliding rail assembly comprises an upper sliding rail body, a motor, a gap eliminating mechanism and a gearbox. The gap eliminating mechanism is fixedly arranged at the two ends of the upper sliding rail body and comprises a support body. The support body is provided with a left shaft and a right shaft. The first wheel and the second wheel are respectively hinged with the left shaft and the right shaft; the third wheel and the fourth wheel are respectively hinged with the bracket body through a lower shaft; the gear box comprises a shell, a worm and a turbine; the worm is meshed with the turbine; the screw rod is fixedly connected with the lower sliding rail; due to the fact that the motor is adopted to drive the worm to drive the worm wheel to rotate, the worm wheel is in threaded connection with the lead screw, the upper sliding rail moves linearly front and back along the lower sliding rail, noise caused by locking and unlocking of a long sliding rail lock in the prior art is avoided through the self-locking function of the worm wheel and the worm, and the riding experience of customers is improved.
本发明涉及一种乘用车电动无级调节长滑轨,属于汽车座椅滑轨领域,包括上滑轨总成和下滑轨;上滑轨总成包括上滑轨本体、电机、间隙消除机构和齿轮箱;间隙消除机构固定设置在上滑轨本体的两端,包括支架本体;支架本体具有左轴和右轴;第一轮和第二轮分别与左轴和右轴铰接;第三轮和第四轮分别通过下轴与支架本体铰接;齿轮箱包括壳体、蜗杆和涡轮;蜗杆和涡轮啮合;丝杆与下滑轨固定连接;涡轮具有内螺纹,其与丝杆螺纹连接,由于采用电机驱动蜗杆带动涡轮旋转,涡轮与丝杆螺纹连接,使上滑轨延下滑轨作前后直线运动,利用涡轮蜗杆的自锁作用,避免现有技术中的长滑轨锁具锁定、解锁时带来的噪音,提升了客户的乘坐体验。
