[0026] Please also refer to Figures 1 to 5 This application provides a train combination headlight and its fixing plate. The fixing plate of the train combination headlight includes a first fixing plate 100 and a second fixing plate 200.

[0027] The first fixing plate 100 is provided with a first mounting hole 110 and a second mounting hole 120. The outer contour of the first fixing plate 100 is generally in the shape of a racetrack. The first mounting hole 110 and the second mounting hole 120 are respectively opened at both ends of the first fixing plate 100.

[0028] The second fixing plate 200 is provided with a third mounting hole 210 and a fourth mounting hole 220. The outer contour of the second fixing plate 200 is generally in the shape of a racetrack. The third mounting hole 210 and the fourth mounting hole 220 are respectively opened at both ends of the second fixing plate 200.

[0029] The second fixing plate 200 is parallel and spaced apart from the first fixing plate 100. The first mounting hole 110 and the third mounting hole 210 correspond to each other for clamping and fixing one vehicle lamp 300. The second mounting hole 120 and the fourth mounting hole 220 correspond to each other for clamping and fixing another vehicle lamp 300.

[0030] The two headlights 300 are positioned and fixed for assembly based on the first mounting hole 110, the third mounting hole 210, the second mounting hole 120, and the fourth mounting hole 220, respectively.

[0031] like Figure 4 As shown, the headlight 300 includes a heat dissipation cylinder 310 and a light-transmitting cover 320. The front outer periphery of the heat dissipation cylinder 310 has a mounting groove 315, and the outer edge of the light-transmitting cover 320 has a mounting ring rib 325 that matches and fits into the mounting groove 315. The bottom of the mounting groove 315 is limited and fixed by a second fixing plate 200, and the outer edge of the light-transmitting cover 320 is limited and fixed by a first fixing plate 100. In other words, the two headlights 300 are clamped and fixed between the first mounting hole 110 and the second mounting hole 120. The wires of the two headlights 300 are connected together through a first connector 510 and electrically connected to a second connector 520 on the train via a plug-in connection.

[0032] like Figure 3 As shown, the second fixing plate 200 is provided with a plurality of screw posts 230 around the third mounting hole 210 and the fourth mounting hole 220, for example, the second fixing plate 200 is provided with 4 screw posts 230 around the third mounting hole 210 and the fourth mounting hole 220, and the first fixing plate 100 is parallel to the second fixing plate 200 through the screw posts 230. The first fixing plate 100 is provided with a plurality of first through holes 131 corresponding to the screw posts 230 around the first mounting hole 110 and the second mounting hole 120. In this embodiment, the first fixing plate 100 is provided with 4 first through holes 131 corresponding to the screw posts 230 around the first mounting hole 110 and the second mounting hole 120, respectively. The fixing plate of the train combination headlight also includes a plurality of first screws 132. The first screws 132 are used to pass through the first through holes 131 and lock with the screw posts 230. In this embodiment, the number of first screws 132 is 8.

[0033] The second fixing plate 200 is provided with a plurality of second fixing holes 240 around the third mounting hole 210 and the fourth mounting hole 220. In this embodiment, the second fixing plate 200 is provided with three second fixing holes 240 around the third mounting hole 210 and the fourth mounting hole 220 respectively. The fixing plate of the train combination headlight also includes a plurality of second screws 241. The second screws 241 are used to pass through the second fixing holes 240 to lock and fix the train combination headlight to the train.

[0034] The first fixing plate 100 is provided with a plurality of tool insertion holes 140, which correspond to the second fixing holes 240 so that the locking tool (screwdriver) can pass through the tool insertion holes 140 to rotate the second screw 241.

[0035] In this embodiment, both the first fixing plate 100 and the second fixing plate 200 are racetrack-shaped, and the distance between the first mounting hole 110 and the second mounting hole 120 is less than the diameter of the headlight 300.

[0036] Furthermore, to ensure accurate installation, the second mounting plate 200 is provided with anti-misfit mounting notches 250 in both the third mounting hole 210 and the fourth mounting hole 220, and the two anti-misfit mounting notches 250 are in different positions. The headlight 300 is provided with an anti-misfit mounting protrusion, which cooperates with the anti-misfit mounting notch 250 to form an anti-misfit assembly.

[0037] The mounting plate of the train combination headlight also includes a silicone ring 400, which is racetrack shaped and located on the side of the second mounting plate 200 away from the first mounting plate 100. The silicone ring 400 is provided with a third mounting hole 410 corresponding to the second mounting hole 240.

[0038] like Figure 4 As shown, the train's combined headlight also includes a ring 330. The ring 330 includes a vertically connected pressure plate 331 and a surrounding cylinder 332 disposed on the outer periphery of the pressure plate 331. The surrounding cylinder 332 is fitted around the outer periphery of the mounting groove 315 and the light-transmitting cover 320. The pressure plate 331 is pressed against the outer edge surface of the light-transmitting cover 320 and is pressed by the first fixing plate 100. The ring 330 can be a silicone part with good elasticity, which plays a certain role in assembly cushioning.

[0039] like Figure 4 and Figure 5 As shown, a reflector cup 340 is provided inside the heat dissipation cylinder 310. The reflector cup 340 includes a conical body 341 and a flange 342. The flange 342 is provided with a connecting post 343. The heat dissipation cylinder 310 is provided with a fourth fixing hole 311 corresponding to the connecting post 343.

[0040] Furthermore, the reflector cup 340 also includes a reinforcing ring 344, which is disposed between the tapered body 341 and the flange 342 and connected to the connecting post 343.

[0041] In summary, those skilled in the art will readily understand that the train combination headlight provided in this application has a novel structure, is easy to assemble, and is stable and reliable. The heat dissipation cylinder 310 and the light-transmitting cover 320 are fixed by the clamping action of the first fixing plate 100 and the second fixing plate 200. When maintenance or replacement is required, the first fixing plate 100 and the second fixing plate 200 can be disassembled for maintenance, which is quite convenient.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
