The invention provides a self-pre-tightening winch and a vertical lifting automobile tailboard using the same, and belongs to the technical field of automobile accessories. Power is output to the speed reducer through the winding and unwinding driver, the main rotating disc is rotationally installed on the output shaft of the speed reducer, the coil spring is arranged between the output shaft and the main rotating disc for transmission, and whether the main rotating disc rotates relative to the output shaft or not is achieved through rotating tightening or reverse rotating loosening of the coil spring; therefore, when the rear tail plate ascends and descends after being unfolded, under the condition that the output shaft is static, the main wheel disc continues to rotate relative to the output shaft through reverse rotation loosening and rotation tightening of the coil spring, and therefore the pull rope can be in a pre-tightening state when the pull rope is loosened due to ascending of the rear tail plate and the pull rope needs to be continuously released due to descending of the rear tail plate. Therefore, the use requirement that the pull rope needs to be continuously released due to descending of the rear tailboard is met, the pull rope can be always kept in a pre-tightening state, neatness is kept, and normal use of the vertical lifting automobile tailboard can be guaranteed.
本发明提供了一种自预紧卷扬机及使用其的垂直升降汽车尾板,属于汽车配件技术领域。本发明通过收放驱动器输出动力至减速器,并将主转盘转动安装于减速器的输出轴上,并于输出轴和主转盘之间设置有卷簧来传动,通过卷簧的旋转拧紧或反旋放松来实现主轮盘是否相对输出轴转动,从而使得在后尾板展开后进行升降时,在输出轴静止的情况下通过卷簧的反旋放松和旋转拧紧来继续使主轮盘相对于输出轴转动,从而实现因后尾板上升而放松的拉绳以及因后尾板下降需要继续释放拉绳时,拉绳均能处于预紧状态,从而适应因后尾板下降而需要继续释放拉绳的使用需求,使得拉绳能始终维持预紧状态,不仅维持了整洁性,还能保证垂直升降汽车尾板的正常使用。
