[0026] like Figures 1 to 3 As shown, a base plate 2 is fixedly connected to the bottom of the door frame 16; a groove 21 is provided on the top of the base plate 2; a guide rod 22 is fixedly connected inside the groove 21; two buffer components 24 are provided at the bottom of the sliding door 14; the two buffer components 24 are symmetrically arranged; a slider 23 is fixedly connected to the bottom of the buffer component 24; the slider 23 slides in the middle of the guide rod 22; during operation, when the sliding door 14 moves, the buffer component 24 buffers the sliding door 14, and the sliding door 14 moves while driving the slider 23 to slide along the guide rod 22. Through the above structure, the sliding door 14 can be effectively guided, so that the sliding door 14 can move along the direction of the guide rod 22, reducing the shaking, deviation or jamming of the sliding door 14 during the movement, thereby making the operation of the sliding door 14 more stable and smooth, and providing users with a good user experience.
