[0002] The rail vehicle gangway is located at the connection of two carriages, and realizes the connection and connection between the two carriages. It is an important dynamic component of the rail vehicle. The side guard plate, as an interior decoration part, is an important component of the gangway. It is installed on both sides of the vehicle body through the side guard plate mounting seat. In order to enable the side guard plate to be quickly disassembled and the vehicle to pass the vehicle height difference and side rolling conditions, rubber baffles are arranged at the upper and lower ends of the side guard plate. The main purpose is to use the flexibility of the rubber to provide operating space for the disassembly of the side guard plate and provide longitudinal deformation for the side guard plate to pass the vehicle height difference and side rolling conditions. Because the rubber baffle of the side guard plate is exposed on the vehicle interior decoration, the outer surface state and installation form of the rubber baffle have a direct impact on the aesthetics of the gangway;

[0003] At present, in the prior art, rubber baffles and mounting connectors mostly adopt a split structure. The rubber baffle is pre-equipped with an mounting cavity. During assembly, the mounting connector needs to be pre-inserted into the mounting cavity and then connected to the side guard plate through the mounting connector. The installation operation is relatively complicated and difficult, and in order to avoid gaps between the side guard plates, the rubber baffles and the side guard plates need to be bonded. As the running time of the vehicle increases, there is a risk of debonding, which affects the appearance of the through-channel side guard plate. Utility Model Content

[0004] The utility model aims to overcome the defects of the prior art and provide a rubber baffle with simple structure, convenient and reliable installation and good installation fit with the side guard plate.

[0008] Wherein, embedded parts are embedded in the rubber plate, and a fitting surface capable of fitting with the outer surface of the side guard plate is formed on the inner side of the rubber plate;

[0009] The embedded parts are provided with connectors at intervals along the length direction of the rubber plate, which are used to connect with the mounting holes provided in the pressing plate, so that the pressing plate and the rubber plate clamp the side guard plate and make the fitting surface fit tightly against the outer surface of the side guard plate.

[0010] Further, a receiving surface extending along the thickness direction of the side guard plate is formed at the bottom end of the rubber plate, and the receiving surface is in contact with the end face of the side guard plate.

[0011] Further, a sealing edge protruding towards the side guard plate is formed at the top end of the rubber plate on the fitting surface.

[0012] Further, a skirt portion extending obliquely downward is formed at the lower part of the rubber plate, and decorative strips are arranged on the outer surface of the skirt portion.

[0013] Further, reinforcing ribs with a crisscross structure are arranged on the inner surface of the skirt portion.

[0014] Further, a wing portion is formed in the middle of the side of the pressing plate body corresponding to the side guard plate, and the wing portion extends towards the side guard plate. Among them, the pressing plate body has a first fitting surface for cooperating with the rubber plate, the wing portion has a second fitting surface for cooperating with the side guard plate, and connecting members are fixedly connected to the positions corresponding to the first fitting surface and the second fitting surface of the embedded part.

[0015] Further, the embedded part includes a bottom plate, and the connecting member is fixedly connected to the bottom plate.

[0016] Further, the structure of the bottom plate is an arc-shaped plate adapted to the outer contour shape of the side guard plate.

[0017] Further, the connecting member is a riveted stud or a rod with an external thread.

[0031] To enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0032] See Figure 1 , 2 as shown;

[0033] The utility model rubber baffle includes:

[0034] a rubber plate 1 and a pressing plate 3 that can be separated from the rubber plate 1;

[0035] Among them, the upper end of the rubber plate 1 is pre-embedded with an embedded part 2. Specifically, the embedded part 2 and the rubber plate blank are vulcanized and formed into one piece in a mold. A fitting surface 11 is formed on the inner side of the rubber plate 1, and the fitting surface 11 can fit with the outer surface of the side guard plate 5. The embedded part 2 is provided with connecting parts 21 at intervals along the length direction of the rubber plate 1, and is connected with the mounting hole opened in the pressing plate 3 through the connecting parts 21. When assembling, the pressing plate 3 and the rubber plate 1 are used to clamp the side guard plate 5 and make the fitting surface 11 fit closely to the outer surface of the guard plate;

[0036] In this structure, an embedded part 2 is integrally formed inside the rubber baffle body 1. The embedded part 21 directly uses its fixed connecting part 21 to pass through the side guard plate mounting hole and the mounting hole on the pressure plate 3 in sequence, thereby realizing the connection between the rubber plate 1, the side guard plate 5, and the pressure plate 3. The installation and disassembly are convenient, and no gluing operation is required.

[0037] In order to ensure the assembly consistency of the rubber sheet 1, a receiving surface 12 extending along the thickness direction of the side guard plate 5 is formed at the bottom end of the fitting surface 11 of the rubber sheet 1. The receiving surface 12 contacts the end surface of the side guard plate 5. During assembly, the side guard plate 5 can be abutted against the receiving surface 12 with the receiving surface 12 as a reference to ensure the accuracy of the assembly position.

[0038] See also Figure 3 , 4 As shown:

[0039] In order to ensure the fitting effect of the upper edge of the rubber sheet fitting surface 11, the rubber sheet 1 is located at the top of the fitting surface 11 to form a sealing edge 16 protruding toward the side guard plate 5. Since the sealing edge 16 protrudes from the fitting surface 11, when assembling, when the connecting piece 21 and the nut 4 cooperate to apply a force to clamp the side guard plate 5 to the rubber sheet 1 and the pressure plate 3, the fitting surface 11 can be deformed toward the side guard plate 5, so that the sealing edge 16 is closely fitted to the outer surface of the side guard plate 5, further improving the fitting effect between the rubber baffle and the side guard plate 5;

[0040] A skirt 13 extending obliquely downward is formed at the lower part of the rubber sheet 1. A decorative strip 14 is arranged on the outer surface of the skirt 13 to decorate the outer surface of the skirt 13 and improve the appearance. The cross-sectional structure of the rubber sheet 1 is adapted to the outer contour of the side guard plate 5 so that it can be wrapped around the outside of the side guard plate 5 during assembly. The inner surface of the skirt 13 is provided with convex ribs 15 with a crisscross structure to improve the structural strength of the rubber sheet 1.

[0041] See also Figure 1 As shown:

[0042] The pressing plate 3 body forms a wing part 31 in the middle of the side of the side guard plate 5. The wing part 31 extends towards the side guard plate 5. Among them, the pressing plate 3 body has a first mating surface for mating with the rubber plate 1, and the wing part 31 has a second mating surface for mating with the side guard plate 5. The embedded part 2 is fixedly connected with a connecting piece 21 at the positions corresponding to the first mating surface and the second mating surface, so that the rubber plate 1 can be connected with the pressing plate 3 in a divided area, ensuring the connection reliability between the pressing plate 3 and the rubber plate 1, and between the pressing plate 3, the rubber plate 1 and the side guard plate 5. In addition, the pressing plate 3 body can extend along the width direction of the side guard plate 5, increasing the contact area between the pressing plate 3 and the rubber plate 1. Through the wing part 31, the middle part of the rubber plate 1 can better fit on the outside of the side guard plate 5, effectively avoiding the generation of gaps between the middle position of the rubber baffle and the side guard plate 5;

[0043] See Figure 4 as shown in:

[0044] The embedded part 2 includes a bottom plate. The bottom plate is fixedly connected with a connecting piece 21. The connecting piece 21 is threadedly connected with a nut 4. The bottom plate is a metal plate. The connecting piece 21 is a riveted stud or a rod with an external thread, such as a screw rod. One end of the rod is fixedly connected with the bottom plate. Secondly, in order to ensure the fitting degree between the rubber plate body and the side guard plate 5, the structure of the bottom plate is an arc-shaped plate adapted to the outer contour shape of the side guard plate 5.

[0045] In the above technical solution, for the rubber baffle provided by the present utility model, the assembly method is as follows:

[0046] First of all, the upper row of connecting pieces 21 on the rubber plate 1 sequentially pass through the side guard plate 5, the mounting holes of the wing part of the pressing plate 3, and the lower row of connecting pieces 21 on the rubber plate 1 pass through the mounting holes of the pressing plate 3 body. The inner surface of the rubber plate 1 is attached to the outer surface of the side guard plate 6 through the attaching surface 11. A gasket and a nut 4 are sequentially installed on the connecting piece 21 and the nut 4 is tightened, so that the attaching surface 11 is closely attached to the outer surface of the side guard plate 6. After the assembly is completed, at this time, under the tightening force provided by the nut 4, the rubber plate 1 can further ensure the fitting effect between the rubber baffle and the side guard plate 6 by using the elastic deformation of the sealing edge 16

[0047] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
