[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figure 1 - Figure 4 This embodiment of a rail transit train approach warning device includes a mounting frame 1. The bottom end of the mounting frame 1 is provided with an alarm mechanism and a display mechanism. The alarm mechanism includes an alarm component 2, which includes a rotating rod 211. The rotating rod 211 is rotatably connected to the bottom end of the mounting frame 1 through a bearing. A sliding rod 210 is slidably provided at the bottom end of the rotating rod 211. A mounting plate 212 is fixedly installed at the bottom end of the sliding rod 210. An alarm sound 28 is provided at the bottom end of the mounting plate 212. A limit rod 213 is slidably provided on the mounting frame 1. A receiving ring 29 is installed at the bottom end of the limit rod 213. The mounting plate 212 is rotatably connected to the inner wall of the receiving ring 29.

[0026] A vertical plate 21 is provided on the mounting bracket 1, and a motor 23 is fixedly installed on the side of the vertical plate 21. A shaft 24 is installed on the rotating shaft end of the motor 23.

[0027] The shaft 24 is cylindrical, and a gear disk 25 is fixedly installed at one end of the shaft 24. The gear disk 25 is frustum shaped.

[0028] The top end of the rotating rod 211 passes through the top end of the mounting bracket 1 and is provided with a frustum gear 22, and the gear disk 25 meshes with the frustum gear 22.

[0029] A frame 26 is fixedly installed at the top of the limiting rod 213. The frame 26 is a strip frame. A drive rod 27 is provided on one side of the gear disk 25. The drive rod 27 is a cylindrical rod and slides on the inner wall of the frame 26.

[0030] The slide bar 210 is a square bar, the mounting plate 212 is a round plate, the limiting bar 213 is a cylindrical bar, and the receiving ring 29 is a circular ring.

[0031] When the alarm needs to be activated upon the arrival of a rail transit train at the station, motor 23 and alarm sound 28 are started. Motor 23 drives shaft 24 to rotate, which in turn drives gear disk 25 to rotate. Gear disk 25 meshes with frustum gear 22, driving frustum gear 22 to rotate. Frustum gear 22, in turn, drives rotating rod 211 to rotate. Since slide rod 210 is slidably mounted at the bottom of rotating rod 211 and is square in shape, rotating rod 211 drives slide rod 210 to rotate. Slide rod 210, in turn, drives mounting plate 212 to rotate, which in turn drives alarm sound 28 to rotate. Simultaneously, gear disk 23... 5. During rotation, the drive rod 27 will also rotate. When the drive rod 27 rotates, it will move the frame 26. When the frame 26 moves, it will move the limit rod 213 vertically back and forth along the through hole between it and the mounting bracket 1. When the limit rod 213 moves vertically back and forth, it will move the receiving ring 29 vertically back and forth. When the receiving ring 29 moves vertically back and forth, since the mounting plate 212 is rotatably connected to the inner wall of the receiving ring 29, the receiving ring 29 will move the mounting plate 212 vertically back and forth, which will drive the alarm sound 28 to move synchronously. Through the above settings, it is convenient to expand the propagation range of the alarm sound 28, which is conducive to reminding passengers to pay attention to safety.

[0032] The display mechanism includes a display component 3, which includes a hinge base 32. The hinge base 32 is fixedly installed on the mounting frame 1. A support plate 31 is rotatably connected to the inner wall of the hinge base 32. A display screen 33 is provided on the support plate 31. An electric telescopic rod 34 is rotatably connected to the inner wall of the mounting frame 1. The telescopic rod end of the electric telescopic rod 34 is rotatably connected to the back of the support plate 31.

[0033] The hinge base 32 is U-shaped, while the support plate 31 and the display screen 33 are both square.

[0034] When the alarm sound 28 sounds, a display screen 33 is provided to display vehicle information and safety precautions. An electric telescopic rod 34 is provided to adjust the tilt angle of the display screen 33, making it easier for passengers to observe the information on the display screen 33.

[0035] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.

[0036] Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing public power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
