[0028] The specific implementation modes of the present invention will be further explained in detail below through the description of embodiments with reference to the accompanying drawings.

[0029] like Figures 1 to 7 As shown, the light skirt structure under the straddle-type monorail vehicle comprises a vehicle body frame, a skirt board, a cantilever, a skirt board support rod and a limit bracket; the skirt board is arranged on the side of the lower part of the vehicle body frame 3, a running wheel 2 is arranged in the middle position of the vehicle body frame, the running wheel is on the track beam 1, a guide wheel 4 is arranged on the side of the vehicle body frame, a cantilever 5 is vertically fixed on the lower part of the vehicle body frame, the upper edge of the skirt board and the top of the cantilever are hingedly connected by a skirt board hinge 9, a limit bracket 10 is arranged on the inner side of the skirt board 8, one end of the skirt board support rod 6 is hingedly connected to the cantilever, a sliding groove is arranged on the limit bracket, and the other end of the skirt board support rod is movably arranged in the sliding groove.

[0030] The cantilever 5 is a cage structure, and a lock structure is provided between the lower edge of the skirt and the bottom of the cantilever; the cage structure of the cantilever forms a ring through the lock and hinge and the fiberglass skirt, so that the whole has sufficient rigidity to ensure normal operation under wind pressure.

[0031] The top of the cantilever is connected to the vehicle body, and the middle of the cantilever is connected to the skirt support rod 6 for supporting the skirt 8; a lock structure is used at the bottom of the cantilever to lock the skirt; the lock structure is a flexible lock, which includes a lock card seat 12, a rubber rod 14 and a lock hook 15. One end of the rubber rod is connected to the lock hook, and the other end is connected to the cantilever. The lock card seat is fixed on the fiberglass skirt board, and the lock hook is clamped in the groove of the lock card seat. The rubber rod is made of a composite material of rubber and steel wire, which has sufficient strength and deformation resistance. While ensuring its own strength, it provides sufficient elastic preload for the flexible lock.

[0032] The skirt board is arranged in sections and is made of glass fiber reinforced plastic. The skirt board support rods are arranged corresponding to the ends of the skirt boards, and two skirt board support rods are arranged at each end of the corresponding skirt board. The other ends of the two skirt board support rods are respectively hingedly connected to the corresponding ends of the rotating pin shaft 7, with a compact structure and stable and reliable support.

[0033] A buffer head mounting seat 16 is provided on the inner side of the bottom of the skirt plate, and a rubber buffer head 11 is provided on the buffer head mounting seat corresponding to the bottom of the cantilever; a spring card 13 is provided on the bottom of the cantilever corresponding to the buffer head mounting seat, and the spring card is provided with a folded edge for clamping on the buffer head mounting seat, and a card groove is provided on the buffer head mounting seat corresponding to the folded edge.

[0034] When locking the skirt board, the skirt board rotates along the skirt board hinge. When the buffer head at the bottom of the skirt board hits the bottom plane of the cantilever, the lock hook is inserted into the lock card seat groove at the bottom of the skirt board and pressed, so that the rubber rod has a certain elastic stretch for pre-tightening and anti-loosening; at the same time, the spring card is fixed at the bottom of the cantilever. When locking the skirt board, the spring card hooks the folded edge of the buffer head mounting seat. The elasticity of the spring card ensures that it will not shake during vibration and will not produce abnormal noise.

[0035] The end of the buffer head 11 is rubber and the tail is a threaded metal rod. The buffer head is connected to the buffer head mounting seat of the skirt board, and the buffer head mounting seat is bonded to the skirt board. When locked, the buffer head contacts the metal surface of the cantilever, and the rubber at the end of the buffer head is deformed with a certain compression force, which can avoid abnormal noise and vibration during vibration.

[0036] When the skirt board is opened, the spring card is pulled out of the folded edge of the buffer head mounting seat, and then the lock hook is pulled out from the lock card seat slot at the bottom of the skirt board, and the skirt board can be rotated along the skirt board hinge. Furthermore, the limit bracket, the buffer head, the lock card seat, the buffer head mounting seat and the skirt board are fixedly connected, and can rotate along the skirt board hinge together with the skirt board.

[0037] A sliding groove is arranged on the limiting bracket 10, and two limiting pits are arranged at both ends of the sliding groove. One end of the skirt board support rod is hinged to the middle rotating pin of the cantilever, and the other end moves along the sliding groove. When the skirt board is opened in place, one end of the skirt board support rod is inserted into the pit of the limiting bracket for positioning. When the skirt board needs to be closed, the end of the skirt board support rod is pulled out of the pit and placed into the sliding groove to close the skirt board.

[0038] The rubber rod in the present invention is made of a composite material of rubber and steel wire, which has sufficient strength and deformation resistance. One end of the rubber rod is connected to the lock hook, and the other end is connected to the cantilever, which provides elastic tension when locked. At the same time, the spring card is fixed to the bottom of the cantilever. When the skirt plate is locked, the spring card hooks the folded edge of the buffer head mounting seat. The elasticity of the spring card ensures that it will not shake during vibration and will not produce abnormal noise. These two sets of elastic positioning structures solve the vibration and abnormal noise problems of the skirt plate mounting assembly.

[0039] The light skirt plate under the straddle-type monorail vehicle of the present invention has a reasonable structural design, is connected to the vehicle body through a cage cantilever and a hinge, and adopts a flexible locking structure at the bottom, which is easy to open and close, stable and reliable; and combined with the fiberglass skirt plate, the effects of block layout, light weight and high rigidity are achieved.

[0040] The above is only an explanation of the preferred embodiments of the present invention, and the above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0041] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
