[0025] Please refer to the accompanying Figure 1 - the accompanying Figure 6 The present application discloses a kind of buffering shock-absorbing garage doors, including slide rail 1, the inner wall of slide rail 1 is slidably connected with garage door main body 2, the symmetric two sides of garage door main body 2 are all provided with first groove 3, first groove 3 is slidably connected with support frame 4, the inner wall of support frame 4 is rotatably connected with roller 6, the side wall of support frame 4 is fixedly connected with first spring 5, the lower end surface of garage door main body 2 is provided with second groove 9, the inner wall of second groove 9 is fixedly connected with fixed rod 8, the inner wall of second groove 9 is slidably connected with damping sleeve 7, the surface of fixed rod 8 is slidably connected with the inner wall of damping sleeve 7, the bottom of fixed rod 8 is fixedly connected with piston plate 10, the surface of piston plate 10 is slidably connected with the inner wall of damping sleeve 7, the upper end surface of piston plate 10 is provided with liquid discharge hole 13, the inside of damping sleeve 7 is provided with liquid storage cavity 12, the inside of damping sleeve 7 is connected with liquid storage cavity 12, the upper end surface of piston plate 10 is fixedly connected with second spring 11, the surface of roller 6 is rotatably connected with the inner wall of slide rail 1, the shape of piston plate 10 is matched with the shape of the inner wall of damping sleeve 7, the shape of damping sleeve 7 is matched with the shape of second groove 9, the number of first groove 3 is matched with the number of support frame 4, the number of support frame 4 is matched with the number of roller 6.

[0026] In example one, the end of first spring 5 away from support frame 4 is fixedly connected with the inner wall of first groove 3.

[0027] Specifically, the first spring 5 generates outward thrust by its own elastic potential energy, drives the support frame 4 to move out of the first groove 3 smoothly, and as the support frame 4 moves, the support frame 4 can adhere the roller 6 to the inner wall of the slide rail 1. When the garage door body 2 starts to move, the roller 6 provides reliable limiting for the running track of the garage door body 2, and at the same time, with its smooth rolling characteristics, reduces the friction between the garage door body 2 and the slide rail 1 due to relative movement, so that the opening and closing process of the garage door is more stable, greatly improving the running efficiency and stability of the entire system.

[0028] In the second embodiment, the top end of the second spring 11 is fixedly connected with the inside of the shock sleeve 7.

[0029] Specifically, when the garage door body 2 descends to the ground, the shock sleeve 7 first contacts the ground, the shock sleeve 7 is extruded into the second groove 9, and the second spring 11 is stretched, and the elastic force of the second spring 11 can reduce the vibration when the garage door body 2 contacts the ground.

[0030] Working principle:

[0031] First, when the driving structure operates to drive the garage door body 2 to descend in the slide rail 1, the first spring 5 promotes the support frame 4 to extend outward from the first groove 3, and then tightly presses the roller 6 against the inner wall of the slide rail 1. In this process, the roller 6 not only precisely limits the displacement of the garage door body 2, but also greatly reduces the frictional resistance between the garage door body 2 and the slide rail 1, ensuring the smoothness and stability of its operation. At the moment when the garage door body 2 slides to the ground, the shock sleeve 7 first contacts the ground, and after being extruded by the ground, slowly shrinks into the second groove 9. This process causes the second spring 11 to stretch, and the elastic force of the second spring 11 effectively buffers the shock impact of the garage door body 2 at the moment of contacting the ground, greatly reducing the possibility of noise generation, and also providing soft protection for the garage door body 2, prolonging its service life. When the second spring 11 vibrates continuously, the hydraulic oil stored in the shock sleeve 7 can flow through the drain hole 13 to suppress the amplitude of the spring. The resistance encountered by the hydraulic oil when passing through the drain hole 13 is always opposite to the vibration direction of the second spring 11, forming a high-efficiency damping effect, so that the vibration of the second spring 11 can decay at a very fast speed, quickly recovering to a stable state, further enhancing the stability and durability of the entire garage door system. Thus, the entire working process is completed.
