[0032] A sleeve 130 for limiting the telescopic rod 120 is fixedly installed in the middle of the mounting plate 110. A tension spring 131 for pulling the telescopic rod 120 is installed inside the sleeve 130. One end of the tension spring 131 is fixedly installed at the bottom of the inner cavity of the sleeve 130, and the other end of the tension spring 131 is fixed at the bottom of the limiting plate 124 so as to facilitate the downward movement of the roller 123 and to buffer the sliding door in conjunction with the inclined side 311.

[0033] The second mounting structure 200 includes a mounting box 210. The inner cavity of the mounting box 210 has grooves 211 on both the front and rear sides for limiting the roller 123. The roller 123 slides in the groove of the groove 211, and the damping structure 300 is installed in the groove of the groove 211.

[0034] The damping structure 300 includes a damping plate 310 for limiting the position of the roller 123, a second bolt 212 for locking the damping plate 310 is installed at the lower end of the mounting box 210, and a third bolt 213 for facilitating the mounting box 210 to be installed on the door frame is installed at the upper end of the mounting box 210.

[0035] One end of the damping plate 310 is machined into an inclined edge 311 to facilitate the movement of the roller 123. One side of the inclined edge 311 is in contact with the bottom of the groove 211, and the horizontal height of the other side of the inclined edge 311 is higher than the bottom of the groove 211. The roller 123 can move from the bottom of the groove 211 to the inclined edge 311.

[0038] When the sliding door with the first mounting structure 100 moves toward the damping structure 300, the roller 123 moves from the lower part of the inclined side 311 to the higher part of the inclined side 311. Under the pull of the tension spring 131, the roller 123 is initially decelerated to slow down the sliding door. When the roller 123 slides on the inclined side 311, it simultaneously drives the damping plate 310 to deform. The side of the damping plate 310 with the connecting plate 314 moves downward, causing the slider 315 to push the telescopic rod 370 downward. The piston 2 371 pushes the gas in the inner cavity of the sleeve 360 ​​toward the connecting pipe 10, and delivers it to the bottom of the inner cavity of the sleeve 2 350 through the connecting pipe 10. The gas pushes the piston 1 342 upward, causing the push plate 340 to simultaneously squeeze the airbag 330. The airbag 330 deforms and pushes the roller 123 to buffer the sliding door and achieve a shock absorption effect.
