Fixed doors 6 are fixedly connected to the left and right sides of the top of the slide rail 2, and the fixed doors 6 are used to maintain the fixed state of the telescopic door. A fixed rod 7 is fixedly connected to the inside of the slide rail 2 to support the structure of the slide rail 2. A slide plate 9 is fixedly connected to the top front side of the wall 1 to guide the movement direction of the telescopic door body 8. The bottom of the slide plate 9 is fixedly connected to the telescopic door body 8, and the bottom of the telescopic door body 8 is fixedly connected to a slider 10, and the slider 10 is used to slide on the slide plate 9;

[0033] The front side of the telescopic door body 8 is fixedly connected to a driving assembly for providing power, and the driving assembly includes a frame 11. The top of the frame 11 is fixedly connected to a motor 12, which serves as a driving source to provide power. The driving end of the motor 12 is fixedly connected to a driving rod 13, which is used to transmit the power of the motor 12. The outside of the frame 11 is fixedly connected to the outside of the telescopic door body 8, and the outside of the driving assembly is rotatably connected to a gear 14. The gear 14 cooperates with the rack 3 to realize the opening and closing movement of the telescopic door body 8. The outside of the slider 10 is fixedly connected to a connecting block 15, which is used to connect the rotating plate 16 and the slider 10. The outside of the connecting block 15 is rotatably connected to a rotating plate 16, which is used to convert the movement of the slider 10 into the telescopic movement of the telescopic door body 8. The outside of the rotating plate 16 is slidably connected to a fixed block 17, which is used to limit the range of movement of the rotating plate 16;

[0034] Reference Figures 3 to 5 , the outside of the telescopic door body 8 is fixedly connected with a plurality of columns 18, which are evenly distributed around the telescopic door body 8, providing additional support for the door body and enhancing its overall stability. A spring 19 is provided inside the column 18. The spring 19 is made of high-strength alloy material, has good elasticity and durability, and is used to buffer the vibration and impact generated by the door body during movement. The outside of the column 18 is slidably connected with a sliding rod 20. The sliding rod 20 has a long strip shape and is made of smooth and wear-resistant material to reduce friction with the column 18. The left and right sides of the outside of the sliding rod 20 are fixedly connected with a connecting frame 21. The connecting frame 21 is made of a solid metal material and is designed as an L-shaped structure to provide stable support for the rotating plate 22. The inside of the connecting frame 21 is rotatably connected to the rotating plate 22. The rotating plate 22 is made of a lightweight and high-strength composite material, which can rotate smoothly and transmit motion to the connecting frame 23. The outside of the rotating plate 22 is rotatably connected to the connecting frame 23;

[0035] The bottom of the connecting frame 23 is fixedly connected to a damper 24. The damper 24 uses advanced hydraulic technology and can automatically adjust the damping force according to the movement speed of the door body to ensure the smooth movement of the door body. The interior of the telescopic door body 8 is fixedly connected to a connecting rod 25. The connecting rod 25 is made of high-strength steel, has a circular cross-section, and is polished to reduce friction with the spring 26. The outer sleeve of the connecting rod 25 is provided with a spring 26. The spring 26 is made of stainless steel and has excellent corrosion resistance and restoring force. It is used to provide a buffering effect when the door body is closed. The outside of the sliding rod 20 is fixedly connected to an anti-collision plate 27. The anti-collision plate 27 is made of rubber material. The raised design on its surface can effectively absorb the impact force and protect the door body from damage caused by accidental collisions. The external sliding connection of the damper 24 is connected to the outside of the telescopic door body 8. Through the precise track design, it is ensured that the damper 24 can maintain linear motion when the door body moves to avoid deviation. The outside of the damper 24 is slidably connected to the outside of the connecting rod 25 , one end of the second spring 26 is fixedly connected to the outside of the damper 24 , and the other end of the second spring 26 is fixedly connected to the inside of the telescopic door body 8 .

[0036] Working principle: by starting the motor 12, under the action of the motor 12, the motor 12 can drive the gear 14 to rotate through the driving rod 13, and under the rotation of the gear 14, the gear 14 can mesh with the rack 3, and then the telescopic door body 8 can slide outside the slide rail 2, and then the two telescopic door bodies 8 can be opened and closed. The doors on both sides can move at the same time or separately. The drive form adopts the gear 14 rack 3. The electronic control system is provided with a door opening button, an open position limit and an indicator light, a door closing button, a close position and an indicator light. This structure can form a self-locking structure. In the case of no motor 12 driving, the door will not be closed by external forces.

[0037] Through the impact of external force, the anti-collision plate 27 can squeeze the spring 19 inside the column 18 through the sliding rod 20, so that the connecting frame 21 outside the sliding rod 20 moves, and under the action of the connecting frame 21, the connecting frame 21 can drive the rotating plate 22 to rotate. Under the rotation of the rotating plate 22, the rotating plate 22 can drive the damper 24 to slide on the outside of the connecting rod 25 through the connecting frame 23. Under the sliding of the damper 24, the damper 24 can squeeze the spring 26, so that the spring 26 is deformed, and then the external force can be removed. When the force disappears, the spring 26 and the spring 19 are reset, and then the anti-collision of the telescopic door body 8 can be achieved.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
