[0052] As described in the background section, in the prior art, the self-cleaning device for train windows requires manual application of glass cleaner to the glass surface for maintenance, resulting in a relatively limited function. Furthermore, when cleaning large areas of train windows, this leads to increased labor costs and reduced efficiency. Therefore, this invention provides a self-cleaning device for train windows, comprising a main body and a controller box. The main body has a receiving chamber for containing cleaning liquid, and is equipped with an inlet and an outlet communicating with the receiving chamber. The outlet is connected to a nozzle. The controller box is located outside the main body and connected to it. The controller box contains a controller and a rotary motor. The motor shaft of the rotary motor extends out of the controller box and is connected to a cleaning head. The controller controls the nozzle to spray cleaning liquid onto the train window and controls the motor shaft to rotate, driving the cleaning head to wipe the train window with the cleaning liquid. This invention improves cleaning efficiency by setting a receiving chamber for holding cleaning liquid on the main body of the device and connecting it with a nozzle for spraying cleaning liquid onto the windows of the EMU train. Furthermore, by separating the controller box and the main body of the device, it prevents cleaning liquid leakage from damaging the controller and affecting the normal operation of the cleaning device.

[0053] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 This invention describes the preferred technical solution of the self-cleaning device and equipment for train windows provided by this utility model.

[0054] like Figure 1 As shown, the self-cleaning device 100 for train windows includes a base 10 and a self-cleaning device 20 for train windows connected to the base 10.

[0055] The self-cleaning device 20 for train windows includes a main body 21 and a controller box 22. The main body 21 is connected to the base 10. The main body 21 has a receiving chamber for containing cleaning liquid. The main body 21 is provided with an inlet 211 and an outlet communicating with the receiving chamber. The outlet is connected to a nozzle 23. The controller box 22 is located outside the main body 21 and connected to it. The controller box 22 contains a controller 221 and a rotary motor 222. The motor shaft of the rotary motor 222 extends out of the controller box 22 and is connected to a cleaning head 25. The controller 221 controls the nozzle 23 to spray cleaning liquid onto the train window and controls the motor shaft to rotate, driving the cleaning head 25 to wipe the train window with the cleaning liquid.

[0056] In addition, a first power module 223 is also provided inside the controller box 22, which provides power support for the controller 221. Optionally, the first power module 223 is a rechargeable battery or the like.

[0057] This invention improves cleaning efficiency by setting a receiving chamber for holding cleaning liquid on the main body 21 of the device and connecting a nozzle 23 for spraying cleaning liquid onto the windows of the EMU train. Furthermore, by separating the controller box 22 and the main body 21 of the device, it prevents the cleaning liquid from leaking and damaging the controller 221, thus affecting the normal operation of the cleaning device.

[0058] As an example, the main body 21 of the device has a box-like structure. The controller box 22 is located on the first side of the main body 21. The fourth side of the main body 21 is used to connect to the base 10, and the fourth side is opposite to the first side. There are two liquid outlets, which are located on the second and third sides of the main body 21 adjacent to the first side, respectively. The second side and the third side are arranged opposite to each other. The nozzle 23 is connected to the liquid outlet through a bend 24.

[0059] Furthermore, the inlet 211 is equipped with a sealing plug to prevent leakage. The outlet is equipped with an electric valve, and the controller 221 controls the nozzle 23 to spray cleaning liquid onto the train windows by controlling the opening and closing of the electric valve; wherein, the electric valve and the controller 221 are wirelessly connected via Bluetooth. It should be noted that the electric valve can adopt a structure commonly used in the art, and will not be described in detail here.

[0060] Optionally, the outer surface of the device body 21 is provided with scale lines 26 to display the liquid level of the cleaning liquid. When the liquid level of the cleaning liquid is low, the cleaning liquid can be added to the receiving chamber through the liquid inlet 211. As an example, the cleaning liquid is windshield washer fluid.

[0061] In some embodiments, the cleaning head 25 includes a connecting assembly 251 and a cleaning brush 252, wherein the connecting assembly 251 is connected to the motor shaft; and the cleaning brush 252 is detachably connected to the connecting assembly 251. This facilitates the removal and replacement of the cleaning brush 252.

[0062] As an example, the connecting assembly 251 includes a mounting plate 2511 and a push-spring snap-fit ​​structure. The mounting plate 2511 is connected to the motor shaft. The push-spring snap-fit ​​structure is connected to the mounting plate 2511 and has a first snap-fit ​​claw 2512 and a second snap-fit ​​claw 2512. The cleaning brush 252 includes a connecting seat 2521 and a polishing brush 2522 connected to the connecting seat 2521. The connecting seat 2521 is provided with a first slot 2523 and a second slot 2524. The first snap-fit ​​claw 2512 and the second snap-fit ​​claw 2512 of the push-spring snap-fit ​​structure respectively push-spring snap-fit ​​with the first slot 2523 and the second slot 2524. Optionally, the polishing brush 2522 may be made of a material with strong water absorption and a certain frictional capacity, such as a sponge or scouring pad, to improve the cleaning effect.

[0063] In detail, the mounting plate 2511 has a first receiving groove and a second receiving groove inside, and a partition 2518 is provided between the first receiving groove and the second receiving groove. The push-and-release structure also includes a first elastic element 2514, a second elastic element 2515, a first button 2516 and a second button 2517. Preferably, the first elastic element 2514 and the second elastic element 2515 are springs.

[0064] The first claw 2512 has a pushing portion that penetrates the mounting plate 2511 and extends into the first receiving groove. The locking portion of the first claw 2512 is located outside the mounting plate 2511. The first elastic member 2514 is embedded between one side of the pushing portion of the first claw 2512 and the partition plate 2518. The first button 2516 penetrates the mounting plate 2511 and is connected to the other side of the pushing portion of the first claw 2512.

[0065] The pushing part of the second claw 2512 penetrates the mounting plate 2511 and extends into the second receiving groove. The snapping part of the second claw 2512 is located outside the mounting plate 2511. The second elastic member 2515 is embedded between one side of the pushing part of the second claw 2512 and the partition plate 2518. The second button 2517 penetrates the mounting plate 2511 and is connected to the other side of the pushing part of the second claw 2512.

[0066] The first claw 2512 and the second claw 2512 are, for example, "L" shaped structures, wherein the vertical extension of the "L" shaped structure constitutes the pushing portion of the first claw 2512 and the second claw 2512, and the horizontal extension of the "L" shaped structure constitutes the engaging portion of the first claw 2512 and the second claw 2512.

[0067] In use, press the first button 2516 and the second button 2517, causing the first button 2516 and the second button 2517 to push the first claw 2512 and the second claw 2512's blocking part to press the first elastic member 2514 and the second elastic member 2515, causing the first elastic member 2514 and the second elastic member 2515 to contract and move towards the partition plate 2518. At this time, the locking part of the first claw 2512 and the second claw 2512 disengages from the first slot 2523 and the second slot 2524 of the connecting seat 2521, losing its limiting effect on the connecting seat 2521. The connecting seat 2521 can then be removed from the mounting plate 2511 for replacement.

[0068] Align the first slot 2523 and the second slot 2524 inside the connector 2521 of the cleaning brush 252 to be replaced with the first claw 2512 and the second claw 2512 engaging upwards. Then release the first button 2516 and the second button 2517, causing the engaging parts of the first claw 2512 and the second claw 2512 to move radially outwards along the first slot 2523 and the second slot 2524 inside the connector 2521, so that the engaging parts of the first claw 2512 and the second claw 2512 are inserted into the first slot 2523 and the second slot 2524 inside the connector 2521 to be fixed, thereby enhancing the adaptability of the device and enabling it to adapt to different application needs.

[0069] It should be noted that the size of the cleaning brush 252 to be replaced can be selected according to the needs. For example, when cleaning a larger area of ​​the car window, replace it with a larger size cleaning brush 252, and when cleaning a smaller area of ​​the car window, replace it with a smaller size cleaning brush 252 to achieve thorough cleaning.

[0070] In some embodiments, the self-cleaning device 20 for the train windows is telescopically connected to the base 10 in the height direction.

[0071] Specifically, the base 10 includes a base 11, a telescopic connecting rod 12, and a limiting block 13. One end of the telescopic connecting rod 12 is connected to the base 11; the limiting block 13 is connected to the other end of the telescopic connecting rod 12 and is connected to the main body 21 of the device.

[0072] It should be noted that the telescopic connecting pole 12 is electrically driven.

[0073] Furthermore, the limiting block 13 has a limiting groove, and a push block 14 is provided in the limiting groove. One end of the push block 14 is connected to a threaded rotating rod 15 that passes through the limiting block 13, and the other end is connected to the device body 21. The threaded rotating rod 15 pushes the push block 14 to drive the device body 21 to extend and retract in the horizontal direction.

[0074] In the above solution, by setting the self-cleaning device 20 in a form that is retractable in both the vertical and horizontal directions, the cleaning area is expanded and the cleaning efficiency of the device is improved.

[0075] In some embodiments, a track module 30 is provided at the bottom of the base 11. The track module 30 is moved in a controlled manner and drives the base 11 to move, thereby realizing the overall movement of the self-cleaning device 100 for train windows.

[0076] Furthermore, the base 11 houses a second power module, a servo motor, and a four-way motor drive board, and includes a Bluetooth module socket and a PS2 controller socket. When the train window self-cleaning device 100 is not in use, the PS2 controller is inserted into the PS2 controller socket to prevent loss. When in use, the PS2 controller is removed from the PS2 controller socket to operate the self-cleaning device 100.

[0077] It should be explained here that the PS2 controller and controller 221 are wirelessly connected via Bluetooth. The operator issues commands to the electric valve, rotary motor 222, drive module of telescopic connecting pole 12, and drive module of track module 30 by operating the buttons on the PS2 controller.

[0078] Optionally, the second power module may be a rechargeable battery or the like.

[0079] The drive module of the track module 30 includes the aforementioned four-motor drive board and a DC motor. The track module 30 includes a drive wheel, a load-bearing wheel, and a single-hole track. The DC motor is electrically connected to the four-motor drive board, and the drive wheel is connected to the central shaft of the DC motor. A load-bearing wheel is provided on one side of the drive wheel, and a single-hole track is provided on the outer side of the drive wheel and the load-bearing wheel. The DC motor controls the driving force to rotate, and then the single-hole track moves in the same direction to realize the overall movement of the train set window self-cleaning device 100.

[0080] Preferably, the four-way motor drive board adopts the TB6612 four-way drive, and the 16-way servo motor model can be PCA9685; the DC motor model is 33 DC motor, the size parameters of the drive wheel are {31.85 (distance between two wheel pieces) * 48.3 (diameter) * 34.08 (connector) mm}, the size parameters of the load-bearing wheel are {20.75 (distance between two wheel pieces) * 47.5 (diameter) * 38 (connector) mm}, and the single-hole track model is TC-09 single-hole track.

[0081] The following reference Figures 1 to 5 This section introduces the working process of the 100 self-cleaning window device for high-speed trains.

[0082] Before use, check that the cleaning fluid inside the main body 21 of the device is sufficient to ensure that the device can be used normally. During use, rotate the threaded rotating rod 15, so that the threaded rotating rod 15 pushes the push block 14 to move in the same direction, so that the cleaning brush 252 can approach the surface of the train window and achieve fine adjustment of the distance; then the drive force is controlled by the DC motor to rotate, and then the single-hole track moves in the same direction to realize the overall movement of the self-cleaning device 100. Automatic cleaning can be achieved by remote control via Bluetooth module and PS2 handle.

[0083] During cleaning, the nozzle 23 sprays cleaning liquid onto the surface of the train window for maintenance, while the rotary motor 222 controls the cleaning brush 252 to clean the window surface. This adds an extra function to the train window self-cleaning device 100 and improves its cleaning efficiency. The cleaning brush 252 can also be replaced or adjusted if the size is unsuitable.

[0084] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
