[0035] Rail transit trains, or train sets, are divided into two main types: railway trains (such as trains) and road trains (such as car train sets, automobile train sets, and road car sets). External cleaning of rail transit trains is crucial. Currently, the brush devices used for cleaning the train exterior mainly employ horizontal or oblique roller brushes, which have limited effectiveness in cleaning the sides of the train exterior.

[0036] In view of this, please refer to the following: Figure 1 This application provides a cleaning structure 10, which includes a main body support 11, a support member 12, a guide rail 13, a cleaning component 14, and a first driving member 15.

[0037] The support member 12 extends out from one side of the main body bracket 11, the guide rail 13 is mounted on the support member 12 at one end away from the main body bracket 11, the cleaning component 14 is movably mounted on the guide rail 13, the first drive member 15 is connected to the cleaning component 14, and the first drive member 15 is configured to drive the cleaning component 14 to move along the length of the guide rail 13 so that the cleaning component 14 washes the train.

[0038] In the cleaning structure 10 of this application embodiment, the cleaning component 14 is movably set on the guide rail 13. Under the connection of the first driving member 15, the cleaning component 14 is driven to move up and down along the direction of the guide rail 13, thereby washing the train. This supplements the washing method of the existing washing equipment, so that the cleaning equipment can wash the train skin evenly and effectively improve the cleaning effect of the cleaning equipment.

[0039] It should be noted that the cleaning structure 10 of this application can be used in conjunction with a cleaning device that employs a horizontal or oblique roller brush pattern in actual cleaning.

[0040] Specifically, the main support 11 can be cylindrical, and its length can be perpendicular to the ground. The main support 11 can adopt a turret-type structure. For example, the main support 11 can include a housing and a central shaft. One end of the central shaft can be fixed to the ground via a tripod. The housing is fitted onto the central shaft and can rotate around it. When the support 12 turns to one side of the train, the housing can be fixed in place by nuts. Furthermore, it should be noted that the overall length of the main support 11 is greater than the height of the train so that the cleaning assembly 14 can thoroughly clean the train's exterior.

[0041] Support member 12 extends from one side of the main body bracket 11 to support guide rail 13. The support member can extend and retract perpendicular to the main body bracket 11. The number of support members 12 can be one or more, and the number is not limited here. For example, in some examples, there can be two support members 12 with equal lengths, arranged in an array along the length of the main body bracket 11, and each connected to the guide rail 13. In other examples, there can be three support members 12 with different lengths, arranged in an array along the length of the main body bracket 11, and each connected to the guide rail 13.

[0042] The guide rail 13 is mounted on the support 12. The material of the guide rail 13 can be metal, and there is no limitation on it. The guide rail 13 can be straight or curved. For example, please refer to... Figure 1 In some examples, the guide rail 13 can be straight, and the guide rail 13 forms its length along the length direction of the body support 11. For example, please refer to... Figure 2 In some examples, the guide rail 13 may be curved, and the curvature of the guide rail 13 is designed to fit the shape of the train shell for thorough cleaning.

[0043] The cleaning component 14 is movably mounted on the guide rail 13 and can move back and forth along the length of the guide rail 13 to clean stains on the train exterior. The number of cleaning components 14 can be one or more, and the number can be set according to the shape of the train; no limitation is made here. For example, please refer to... Figure 1 When the number of cleaning components 14 is one, it is convenient for cleaning the train's flat exterior; for example, please combine with Figure 2 When there are multiple cleaning components 14, they are curved to suit the shape of the train shell, making cleaning easier.

[0044] The first drive component 15 is mounted on the guide rail 13 and is movably connected to the cleaning component 14. It is configured to drive the cleaning component 14 to move along the length of the guide rail 13 so that the cleaning component 14 can wash the train shell.

[0045] Please see Figure 1 In some embodiments, the cleaning mechanism 10 further includes a second drive member 16, which is located on the body support 11 and connected to the support member 12. The second drive member 16 is configured to drive the support member 12 to move in a direction perpendicular to the body support 11.

[0046] Specifically, the second driving element 16 can be a pneumatic actuator. It should be noted that a pneumatic actuator is an actuator that uses air pressure to drive the opening, closing, or regulation of a valve. The second driving element 16 can be fixed to the top of the main body bracket 11 and movably connected to the support member 12. The second driving element 16 and the support member 12 can be connected by gear meshing. The second driving element 16 is used to drive the support member 12 to move along the vertical direction of the main body bracket 11.

[0047] Thus, by setting the second driving component 16, the support component 12 and the guide rail 13 installed on the support component 12 can be driven to move in a direction perpendicular to the main body bracket 12. The cleaning component 14 is located on the guide rail 13, so the cleaning component 14 can be moved closer to or further away from the train, thereby flexibly adjusting the distance between the cleaning component 14 and the car body to adapt to different car bodies.

[0048] Please see Figure 1 In some embodiments, the cleaning assembly 14 includes a rotating wheel 141, a brush 142, and a safety wheel 143.

[0049] Specifically, the rotating wheel 141 is movably mounted on the guide rail. The number of rotating wheels 141 can be multiple and is not limited here. The rotating wheel 141 is used to drive the brush plate 142 to reciprocate along the guide rail 13 in the direction of the length of the guide rail 13.

[0050] The brush plate 142 is located on the side of the rotating wheel 141 away from the guide rail and is used to clean the train. The brush plate 142 may include two parts: bristles and plate body. The bristles may be made of polybutylene terephthalate (PBT) filaments, which makes the bristles soft and suitable for cleaning and removing dirt from delicate parts. The plate body is roughly rectangular and can be made of wood or plastic. The plate body is connected to the rotating wheel 141 and the first drive member 15.

[0051] Safety wheels 143 are installed on the side of the brush plate 142 away from the main body bracket 11. During cleaning, the safety wheels are spaced apart from the train shell. When the safety wheels 143 collide with the train shell, a collision signal is generated and transmitted to the second drive member 16. After receiving the signal, the second drive member 16 will drive the support member 12 to move towards the main body bracket 11, thereby moving the cleaning components away from the train shell.

[0052] Furthermore, the safety wheel 143 may be equipped with a pressure sensor to generate a warning signal when the safety wheel 143 collides with the train. When the pressure sensor of the safety wheel 143 senses that the amount of bristles picked up by the brush plate 142 exceeds the safe amount of bristles picked up, an alarm signal is generated and transmitted to the second drive member 16. The second drive member 16 can drive the support member to move the guide rail and the brush plate 142 away from the train according to the alarm signal, thereby avoiding damage to the train caused by the brush plate 142 when cleaning the train.

[0053] Please see Figure 2 In some embodiments, the first drive member 15 includes a pneumatic member 152, which is mounted on the guide rail 13 and connected to the brush plate 142.

[0054] Specifically, the first driving component 15 can be a pneumatic component 152. It should be noted that the pneumatic component 152 refers to a pneumatic component that converts the elastic energy of compressed air into kinetic energy. The pneumatic component 152 is fixedly connected to the guide rail 13 and movably connected to the brush plate 142. The pneumatic component 152 can be a cylinder. The cylinder guides the piston to perform linear reciprocating motion within the cylinder, which drives the brush plate 142 to perform reciprocating motion on the guide rail 13, thereby realizing the cleaning component 14 cleaning the train shell.

[0055] Thus, the pneumatic component 152 of the first driving component 15 adopts a cylinder structure, which makes the overall structure simple, lightweight, easy to install and maintain, highly reliable, and long-lasting.

[0056] Please see Figure 3 In some embodiments, the first drive member 15 further includes a cam 151, which is rotatably mounted on the guide rail 13 and movably connected to the brush plate 142.

[0057] Specifically, the first driving component 15 can be a cam 151. It should be noted that the cam 151 is a component with a curved profile or a groove shape, which is fixedly connected to the guide rail 13 and movably connected to the brush plate 142 linkage. It can be driven by a geared motor or a pneumatic actuator 16 to make a constant speed rotary motion or reciprocating linear motion on the guide rail 13. The cam 151 acts to drive the brush plate 142 linkage to reciprocate along the length of the guide rail 13, thereby causing the brush plate 142 to reciprocate to clean the train shell.

[0058] Thus, the first drive component 15 can achieve higher frequency reciprocating motion by selecting a geared motor with a higher rotation speed, thereby improving cleaning efficiency.

[0059] Please see Figure 2 In some embodiments, the cleaning components 14 include a plurality of cleaning components 14 arranged at intervals on the guide rail 13.

[0060] Specifically, in some examples, multiple cleaning components 14 are arranged at intervals on the guide rail 13, and the number is not limited. For example, in some examples, arranging one cleaning component 14 on the guide rail 13 of the same length would require a lot of time to clean the train shell of the same length and height; in other examples, arranging multiple cleaning components 14 on the guide rail 13 of the same length would take less time to clean the train shell of the same length and height than arranging one component.

[0061] Thus, the number of cleaning components 14 determines the efficiency of cleaning the train's exterior.

[0062] Please see Figure 2 In some implementations, the multiple cleaning components 14 have different lengths.

[0063] Specifically, the lengths of the cleaning components 14 may not be uniform. Different structural choices for the first drive member 15 and different numbers of support members 12 result in the brush plate 142 needing to be divided into multiple parts, each with a different length. For example, in some cases, using a cam 151 as the first drive member 15 requires three support members 12 to support the guide rail 13. The support members 12 divide the brush plate 142 into two parts, each with a different length of the cleaning component 14.

[0064] Thus, the length of the cleaning component 14 can be adjusted according to the different structures of the first drive component 15.

[0065] Please see Figure 2 In some embodiments, the guide rail 13 is arc-shaped.

[0066] Specifically, the guide rail 13 can be arc-shaped; please refer to... Figure 4In some examples, the curvature of guide rail 13 is designed to match the shape of the train's outer shell, thus achieving the purpose of thorough cleaning.

[0067] Please see Figure 1 In some embodiments, the guide rail 13 is formed along the length direction of the body support 11.

[0068] Specifically, the guide rail 13 can be made of metal, and there is no limitation on its material. The guide rail 13 can be straight or curved; for example, please refer to... Figure 1 In some examples, the guide rail 13 can be straight, and the guide rail 13 forms its length along the length direction of the body support 11. For example, please refer to... Figure 2 In some examples, the guide rail 13 may be curved, and the curvature of the guide rail 13 is designed to fit the shape of the train shell for thorough cleaning.

[0069] This application also provides a cleaning device, including the cleaning mechanism 10 described above.

[0070] Specifically, the cleaning equipment may also include a washing device that uses a horizontal or oblique roller brush pattern, and the washing device and the cleaning mechanism 10 are used together during the cleaning process.

[0071] The cleaning equipment of this application embodiment, through the effect of the cleaning mechanism 10, uses a support member 12 extending towards the train side on the main body bracket 11 to fix the guide rail 13 required by the first drive member 15 to one end away from the support member 12 on the main body bracket 11. The cleaning component 14 is movably mounted on the guide rail 13. Under the connection of the first drive member 15, the cleaning component 14 is driven to move up and down reciprocally along the direction of the guide rail 13, thereby washing the train. This supplements the washing method of existing washing equipment, enabling the cleaning equipment to wash the train exterior evenly and effectively improving the cleaning effect of the cleaning equipment.

[0072] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with the described embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
