[0032] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0033] Example:

[0034] This embodiment introduces a structure for a decorative cover plate on an upper side wall of a rail transit vehicle.

[0035] like Figure 1 , 2 As shown, Figure 1 This is a structural schematic diagram of a decorative cover plate for the upper side wall of a rail transit vehicle according to the utility model. Figure 2 The figure is an overall schematic diagram of a decorative cover plate applied to the upper side wall of a rail transit vehicle.

[0036] A decorative cover plate for the upper side wall of a rail transit vehicle, comprising a mounting platform 1 formed by a groove on the side wall of the vehicle, a side wall cover plate 2, and a rotating mechanism 3;

[0037] Adhere 3M industrial buckles 4 on the installation platform 1, and install the side wall cover plate 2 on the installation platform 1 through the 3M industrial buckles 4;

[0038] The rotating mechanism 3 is movably installed on the side wall cover plate 2.

[0039] Among them, the installation platform 1 is formed by a Z-shaped fiberglass bonding part at the position where the vehicle side wall is grooved.

[0040] In this embodiment, after applying 3M94V0 primer at the corresponding position of the installation platform, bond 3M industrial fastener SJ3550 (Type250), tear off the backing release paper, and preliminarily bond and fix the side wall cover plate.

[0041] As Figure 3 shown, Figure 3 is a schematic diagram of a rotating mechanism in the upper side wall decorative cover plate applied to a rail transit vehicle. The rotating mechanism 3 includes an upper layer plate 3-1, a fixing plate 3-2, and a locking tongue plate 3-3. An installation post 3-4 is press riveted on the upper layer plate 3-1, and the fixing plate 3-2 and the locking tongue plate 3-3 are sequentially sleeved under the upper layer plate 3-1 through the installation post 3-4;

[0042] A self-locking nut 3-5 is embedded in the fixing plate 3-2. Corresponding installation holes 3-7 are opened on the upper layer plate 3-1 and the locking tongue plate 3-3. Screws pass through the installation holes 3-6 and the self-locking nut 3-5 to complete the installation of the rotating mechanism 3.

[0043] In this embodiment, M3 screws are used to lock and fix the upper layer plate, the fixing plate, and the locking tongue plate to complete the stable connection of the rotating mechanism.

[0044] In this embodiment, the three parts of the rotating mechanism 3 are respectively cut from 3 pcs of stainless steel plates with different thicknesses.

[0045] Furthermore, installation holes 3-7 with the same position are provided on the upper layer plate 3-1, the fixing plate 3-2, and the locking tongue plate 3-3.

[0046] As Figure 4 , 5 shown, Figure 4 is a schematic diagram of a side wall cover plate in the upper side wall decorative cover plate applied to a rail transit vehicle, Figure 5 is a schematic diagram of the installation hole 3-7 in the upper side wall decorative cover plate applied to a rail transit vehicle. An installation hole 3-2 is opened on the side wall cover plate 2. The installation hole 3-2 corresponds to the installation hole 3-7. The rotating mechanism 3 is fixedly installed on the side wall cover plate 2 through the installation hole 3-2 and the installation hole 3-7 with a locking screw 5.

[0047] In this embodiment, the locking screw selected is an M3 countersunk head screw, and the rotating mechanism is installed on the side wall cover plate.

[0048] AsFigure 6 As shown Figure 6 Figure 6 is another perspective view of the upper sidewall decorative cover plate applied to rail transit vehicles. A positioning pin 2-1 is press riveted on the sidewall cover plate 2.

[0049] Among them, the positioning pin 2-1 serves as a reference for the installation of the rotating mechanism and also plays a limiting role.

[0050] For ease of understanding, the following description is provided: As Figure 7 shown Figure 7 Figure 7 is a schematic diagram of the initial state of the rotating mechanism shown. In the initial state of the rotating mechanism 3 installed on the sidewall cover plate 2, the rotating mechanism 3 is located on one side of the positioning pin 2-1, and the locking tongue plate 3-3 is limited by the positioning pin 2-1 and can rotate counterclockwise.

[0051] As Figure 8 shown Figure 8 Figure 8 is a schematic diagram of the locked state of the rotating mechanism shown. Rotate the rotating mechanism 3 in the initial state counterclockwise by 90° to the sidewall of the installation platform 1, which further strengthens the connection between the sidewall cover plate and the vehicle sidewall and improves the stability of the installation of the sidewall cover plate. Specifically, after rotating the rotating mechanism 3 counterclockwise by 90°, the rotating mechanism 3 contacts the positioning pin 2-1 on the sidewall cover plate 2. At this time, the rotating mechanism 3 cannot rotate further under the action of the positioning pin 2-1, and the locking tongue part protruding from the front end of the locking tongue plate 3-3 on the rotating mechanism 3 will complete the lap joint with the sidewall of the installation platform 1. Continuing to tighten the locking screw 5 will cause the rotating mechanism 3 to drive the self-locking nut 3-5 to clamp with the sidewall cover plate 2, thereby completing the further firm connection between the sidewall cover plate and the vehicle sidewall.

[0052] Furthermore, the sidewall cover plate 2 is made of aluminum alloy material. In this embodiment, 5052 aluminum alloy material is selected, and its thickness is 2 mm.

[0053] This kind of upper sidewall decorative cover plate applied to rail transit vehicles introduced in this embodiment has a simple structure, a fast installation method, greatly improved stability, and does not require excessive processing of the vehicle sidewall panel. Only a cover plate installation space needs to be reserved; it is firmly installed after installation and is not easy to fall off. Since there are few surface screw holes, it does not affect the aesthetics.

[0054] The above description is only an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
