The invention provides a wheelbase adjusting mechanism and a lifting device comprising the wheelbase adjusting mechanism, the wheelbase adjusting mechanism comprises a wheel bearing unit used for bearing vehicle wheels and a guiding unit, the guiding unit comprises a cone pulley and a sliding groove which are matched, the cone pulley is arranged on the wheel bearing unit, the sliding groove extends in the vehicle running direction, the cone pulley is matched with the sliding groove in shape, and the guiding unit is arranged on the guiding unit. Therefore, the wheel bearing unit is guided to perform position adjustment along the vehicle driving direction. The guide unit can guide the moving direction of the wheel bearing unit, the accuracy of the moving direction of the wheel bearing unit is guaranteed, the moving smoothness of the wheel bearing unit is improved, and the unilateral displacement of the wheel bearing unit in the width direction of the vehicle can be limited by matching of the peripheral slope of the conical wheel and the inner surface of the notch of the sliding groove. And the electric vehicle cannot deviate in the width direction of the vehicle, so that the battery replacement equipment can be accurately aligned with the electric vehicle, and the battery replacement success rate and the battery replacement efficiency are improved.

    本发明提供一种轴距调节机构及包括其的举升装置,轴距调节机构包括用于承载车辆车轮的车轮承载单元以及导向单元,导向单元包括匹配的锥轮和滑槽,锥轮设于车轮承载单元上,滑槽沿车辆行驶方向延伸,锥轮与滑槽的形状匹配,以引导车轮承载单元沿车辆行驶方向进行位置调节。导向单元能够引导车轮承载单元的移动方向,保证车轮承载单元移动方向的准确性,并提高车轮承载单元移动的流畅性,锥轮的外周斜面与滑槽的槽口内表面配合还可以限制车轮承载单元在车辆宽度方向上的单侧位移。电动汽车不会沿车辆宽度方向产生偏移,使得换电设备可以准确对准电动汽车,提高换电成功率和换电效率。
