[0002] At present, the driving methods of electric sliding doors on the market are divided into cable drive and belt drive according to the transmission structure. Among them, belt drive uses the friction between the belt roller and the belt to drive the opening and closing of the sliding door. However, due to the structure and design characteristics of the belt transmission system, the belt roller and the bracket require a large space to be arranged, the transmission efficiency is low, and the transmission ratio may fluctuate over time, thus affecting the accuracy and stability of the transmission. At the same time, the rubber material used in the belt may deform and fail due to excessive temperature, or even break; the cable drive uses the cable to load the motor driving force to the sliding door hinge, so that the sliding door can achieve reciprocating movement relative to the body, which is more efficient than the belt drive. However, in the existing cable drive structure, the cable end is prone to interference with other components in the transmission structure, which destroys the power transmission and even causes wear on the cable. When replacing, the entire cable needs to be disassembled, which is time-consuming and labor-intensive. Utility Model Content
