[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] Embodiment 1

[0027] As Figures 1-4As shown in the figure, a C-shaped elastic wall panel for urban rail subway includes a guard plate assembly 1, a rotating cylinder mechanism 2, and an operation module 3. There are two rotating cylinder mechanisms 2, symmetrically arranged on both sides of the guard plate assembly 1. The two sides of the guard plate assembly 1 are in a drum structure, covering the outside of the aluminum cylinder 21 of the rotating cylinder mechanism 2 and fixedly connected to the aluminum cylinder 21. The rotating cylinder mechanism 2 drives the relative rotation of both sides of the guard plate assembly 1 to achieve the contraction and stretching of the guard plate. The two sides of the guard plate assembly 1 move symmetrically, and the forces on the C-shaped elastic wall panel cancel each other out, with small force. The telescopic amount is stretched (exhibited) or contracted with the movement of the rotating sleeve mechanism. The operation module 3 is arranged on the rotating cylinder mechanism 2, including a sliding rod 31, a sliding seat 32, a sliding block 33, a pulling rope 34, and an operating part. The sliding rod 31 is fixedly connected to the vehicle body, and a chute 311 is arranged on it along the axial direction of the aluminum cylinder 21. The sliding block 33 is inserted into the chute 311 and slidably connected to the chute 311. The sliding seat 32 is fixedly connected to the sliding block 33 through a fastener passing through the chute 311. One end of the pulling rope 34 is fixedly connected to the aluminum cylinder 21, and the other end bypasses the outside of the aluminum cylinder 21 and is connected to the sliding seat 32. The operating part is connected to the sliding seat 32 and can drive the sliding block 33 to slide along the chute 311. Two limiting holes 312 are also arranged on the sliding rod 31, and the two limiting holes 312 are arranged outside the chute. A spring pin 36 matching the limiting hole 312 is arranged on the sliding seat 32. By operating to drive the sliding block 33 to slide along the chute, the spring pin 36 on the sliding seat 32 approaches the limiting hole 312, and then the spring pin 36 is inserted into the limiting hole 312 to lock the position of the sliding seat 32, so as to unlock or lock the position of the aluminum cylinder 21 through the pulling rope 34. The structure is simple and the operation is convenient, making the disassembly and assembly of the guard plate assembly more convenient.

[0028] Among them, as Figures 1-2 shown, the guard plate assembly 1 includes a guard plate 11 and a covering plate 12. The guard plate 11 is a flexible integral C-shaped plate, and the covering plate 12 is made of rubber and is located at the upper and lower ends of the guard plate 11. The guard plate 11 is inserted into the insertion groove at the end of the covering plate 12 and is fixedly connected to the covering plate 12 through a fastener. After the covering plate 12 is installed, it is integrated with the interior decoration of the vehicle body. When the guard plate moves up and down, the side guard plate can keep consistent with the movement of the vehicle body, improving the overall aesthetic effect of the side wall. In addition, the guard plate assembly 1 further includes a sound insulation cotton layer 13 arranged on the inner side of the guard plate, which can improve the sound insulation effect of the through passage.

[0029] In order to further improve the overall aesthetic effect of the side wall, as Figures 1-2 shown, the above-mentioned C-shaped elastic wall panel for urban rail subway further includes a lock cover plate assembly 4 arranged on both sides of the guard plate assembly. The lock cover plate assembly 4 is connected to the rotating cylinder mechanism 2 and is used to block the gap between the guard plate assembly 1 and the vehicle body, avoiding pinching hands and improving safety.

[0030] Specifically, the lock cover plate assembly 4 includes a cover plate 41, a brush strip 42, and a rubber strip 43. The cover plate 41 is connected to the mounting seat 26 of the rotating cylinder mechanism 2 through fasteners. One end of the cover plate 41 close to the guard plate 11 is sequentially provided with a brush strip 42 and a rubber strip 43 in the direction from inside to outside. The brush strip 42 abuts against the outer side of the winding drum part of the guard plate 11, and the rubber strip 43 is connected to the outer side of the winding drum part of the guard plate 11 with a gap. Through this setting, in addition to ensuring the shielding function of the lock cover plate assembly 4, it also avoids friction marks or wear caused by the friction between the rubber strip 43 and the guard plate 11.

[0031] Embodiment 2

[0032] Based on the structure of Embodiment 1, as Figure 1 shown, the rotating cylinder mechanism 2 includes an aluminum cylinder 21, a rotating shaft 22, a torsion spring 23, a first rotating sleeve 24, and a second rotating sleeve 25. The rotating shaft 22 is inserted inside the aluminum cylinder 21, is coaxially arranged with the aluminum cylinder 21, and is fixedly connected to the vehicle body. The torsion spring 23 is sleeved on the rotating shaft 22, its lower end is fixedly connected to the rotating shaft 22, and its upper end is connected to the aluminum cylinder 21 and is rotatably connected to the rotating shaft 22; the first rotating sleeve 24 and the second rotating sleeve 25 are both fixedly connected to the aluminum cylinder 21, and are both sleeved outside the rotating shaft 22 and are rotatably connected to the rotating shaft 22 through bearings arranged inside. The first rotating sleeve 24 is arranged at the lower end of the aluminum cylinder 21, and the second rotating sleeve 25 is arranged at the upper end of the aluminum cylinder 21 and is connected to the rotating end of the torsion spring 23.

[0033] In the above structure, as Figures 1-4 shown, the rotating cylinder mechanism 2 further includes two mounting seats 26 arranged at both ends of the rotating shaft 22. One end of the mounting seat 26 is clamped and fixed outside the rotating shaft 22 through a clamping block, and one end extends from the rotating shaft 22 to the outside of the aluminum cylinder 21 and is connected to the vehicle body, improving the overall stability of the rotating cylinder mechanism 2; a sliding rod 31 is installed between the two mounting seats 26, and the sliding rod 31 is fixedly connected to the vehicle body through the mounting seats 26.

[0034] As Figure 1 、 3 -4 shows, one end of the pull rope 34 is fixedly connected to the aluminum cylinder 21 through a pull rope buckle arranged on the second rotating sleeve 25, and the other end sequentially bypasses the outside of the aluminum cylinder 21, passes through a guiding joint 35 on the sliding rod 31 and is connected to a pull rope buckle arranged on the sliding seat 32. The guiding joint 35 is arranged inside the upper end of the sliding rod 31. The guiding joint 35 guides the moving track of the pull rope, ensuring that the second rotating sleeve 25 rotates by a corresponding angle as the slider 33 slides, thereby driving the aluminum cylinder 21 to rotate.

[0035] In addition, as Figures 3-4As shown, the operating member includes an operating arm 37 and an operating rod 38. One end of the operating arm 37 is hinged to the sliding seat 32, and the other end is hinged to the middle of the operating rod 38. One end of the operating rod 38 is the operating end, and the other end is hinged to a hinge seat 38 provided below the sliding seat 32. For ease of operation, the operating end of the operating rod 38 is provided in a handle shape, and the hinge seat is fixed on the sliding rod. The structure of the operating member is simple and easy to operate, improving convenience. It should be noted that when the guard plate assembly 1 is in the working state, the operating end of the operating rod 38 is inserted into the chute 311, which has a certain limiting effect; when it is necessary to disassemble the guard plate assembly 1, first remove the lock cover plate assembly 4, and then push down the operating rod 38 to rotate the aluminum cylinder 21 towards both sides, so that the guard plate 11 is in a stretched state, facilitating subsequent disassembly.
