[0040] Embodiment 2

[0041] Based on the structure of Embodiment 1, as Figures 7-8 shown, the side guard plate assembly 3 includes a guard plate assembly 31 and a rotating cylinder mechanism 32. The guard plate assembly 31 is a flexible one-piece structure, and two symmetrically arranged rotating cylinder mechanisms 32 are provided on both sides thereof. The rotating cylinder mechanism 32 includes an aluminum cylinder 321, a rotating shaft 322, and a torsion spring 323. The rotating shaft 322 is inserted into the aluminum cylinder 321, is coaxially arranged with the aluminum cylinder 321, and is fixedly connected to the vehicle body. The torsion spring 323 is sleeved on the rotating shaft 322, its lower end is fixedly connected to the rotating shaft 322, and its upper end is connected to the aluminum cylinder 321 and is rotatably connected to the rotating shaft 322. Both sides of the guard plate assembly 31 are in a reel structure and are covered and fixed outside the aluminum cylinder 321.

[0042] In the above structure, as Figures 7-8 shown, the guard plate assembly 31 includes a guard plate 311 and a covering plate 312. The guard plate 311 is a flexible integral C-shaped plate, and the covering plate 312 is made of rubber and is located at the upper and lower ends of the guard plate 311. The guard plate 311 is inserted into the insertion slot at the end of the covering plate 312 and is fixedly connected to the covering plate 312 through fasteners. After the covering plate 312 is installed, it is integrated with the vehicle interior trim. When the guard plate 311 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 guard plate assembly 31. Moreover, the guard plate assembly 31 adopts a one-piece structure, with good aesthetic effect and no wear on the appearance. In addition, the guard plate assembly 1 further includes a sound insulation cotton layer 13 provided on the inner side of the guard plate, which can improve the sound insulation effect of the gangway.

[0043] In addition, asFigures 7-10 As shown, the rotary drum mechanism 32 further includes a first rotating sleeve 324, a second rotating sleeve 325, and two mounting seats 326 provided at both ends of the rotating shaft 322. The first rotating sleeve 324 and the second rotating sleeve 325 are both fixedly connected to the aluminum cylinder 321, and are both sleeved outside the rotating shaft 322 and rotatably connected to the rotating shaft 322 through bearings provided inside. The first rotating sleeve 324 is provided at the lower end of the aluminum cylinder 321, and the second rotating sleeve 325 is provided at the upper end of the aluminum cylinder 321 and is connected to the rotating end of the torsion spring 233. One end of the mounting seat 326 is clamped and fixed outside the rotating shaft 322 through a clamping block, and one end extends from the rotating shaft 322 to the outside of the aluminum cylinder 321 and is connected to the vehicle body, improving the overall stability of the rotary drum mechanism 32.

[0044] In addition, as Figure 7 , 9 , as shown in Figure 10, the side guard plate assembly 3 further includes an operation module 33 for assisting in the disassembly and assembly of the guard plate assembly. The operation module 33 includes a slide bar 331, a slide seat 332, a slider 333, a pull rope 334, and an operating member. Both ends of the slide bar 331 are respectively fixed on a mounting seat 326. A chute 3311 is provided on the slide bar 331 along the axial direction of the aluminum cylinder 321. The slider 333 is inserted into the chute 3311 and is slidably connected to the chute 3311. The slide seat 332 is fixedly connected to the slider 333 through a fastener passing through the chute 3311. One end of the pull rope 334 is connected to a pull rope buckle provided on the second rotating sleeve 325, and the other end sequentially bypasses the outside of the aluminum cylinder 321, passes through a guiding joint 335 on the slide bar 331 and is connected to a pull rope buckle provided on the slide seat 332. The guiding joint 335 guides the moving track of the pull rope 334, ensuring that the second rotating sleeve 325 rotates by a corresponding angle as the slider 333 slides, thereby driving the aluminum cylinder 321 to rotate. The operating member is connected to the slide seat 332 and is used to drive the slider 333 to slide along the chute 3311, and includes an operating arm 337 and an operating rod 338. One end of the operating arm 337 is hinged to the slide seat 332, and the other end is hinged to the middle of the operating rod 338. One end of the operating rod 338 is an operating end, and the other end is hinged to a hinge seat 339 provided below the slide seat 332. For the convenience of operation, the operating end of the operating rod 338 is set in the shape of a handle. The hinge seat 339 is fixed on the slide bar 331. Two limiting holes 3312 are further provided on the slide bar 331, and a spring pin 336 matching the limiting holes 3312 is provided on the slide seat 332.

[0045] By driving the slider 333 to slide along the chute 3311 through the operating rod 338, the spring pin 336 on the slide seat 332 is brought close to the limiting hole 3312, and then the spring pin 336 is inserted into the limiting hole 3312 to lock the position of the slide seat 332, thereby unlocking or locking the position of the aluminum cylinder 321 through the pull rope 334. The structure is simple and the operation is convenient, making the disassembly and assembly of the guard plate assembly 31 more convenient. In addition, when the guard plate assembly 31 is in the working state, as Figure 10As shown, the operating end of the operating rod 338 is inserted into the sliding groove 3311, which has a certain limiting effect. When the guard plate assembly 31 needs to be disassembled, first remove the lock cover plate assembly 34, as Figure 9 shown, and then push down the operating rod 338 to rotate the aluminum cylinder 321 towards both sides, so that the guard plate is in a stretched state, facilitating subsequent disassembly.

[0046] In addition, as Figures 7-8 shown, the side guard plate assembly 3 further includes lock cover plate assemblies 34 provided on both sides of the guard plate assembly 31. The lock cover plate assemblies 34 are connected to the rotating cylinder mechanism 32 and are used to block the gap between the guard plate assembly 31 and the vehicle body, avoiding pinching hands and improving safety. Specifically, the lock cover plate assembly 34 includes a cover plate 341, a brush strip 342, and a rubber strip 343. The cover plate 341 is connected to the mounting seat 326 of the rotating cylinder mechanism 32 through fasteners. At one end close to the guard plate 311, a brush strip 342 and a rubber strip 343 are provided in sequence along the direction from inside to outside. The brush strip 342 abuts against the outer side of the winding part of the guard plate 311, and the rubber strip 343 is connected to the outer side of the winding part of the guard plate 311 with a gap. Through this setting, in addition to ensuring the blocking function of the lock cover plate assembly 34, it also avoids friction marks or wear caused by the friction between the rubber strip 343 and the guard plate 311.
