[0002] AGVs (Automated Guided Vehicles) are automated guided vehicles used for transporting goods and handling materials in factories, warehouses, hospitals, and other similar locations. AGVs are typically equipped with sensors and navigation systems, enabling them to move autonomously along pre-set paths and perform various tasks, such as moving goods, transporting materials, and performing assembly tasks. AGVs play a vital role in industry and logistics, improving production efficiency, reducing costs, and enhancing the automation level of logistics transportation.

[0003] However, during use, the wheels of AGV vehicles easily get dirty, and some workshops have high environmental requirements, thus necessitating the cleaning of AGV vehicle wheels. In existing technologies, manual or automated cleaning devices are typically used to clean the AGV vehicle wheels.

Therefore, they should not be construed as limitations on this application.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0039] Please refer to the following: Figures 1-13 The AGV wheel cleaning equipment provided in the embodiments of this application will now be described.

[0040] An AGV wheel cleaning device includes a housing 1, which is provided with a cleaning area 2, a wiping area 3 and a collection area 4 in sequence. The cleaning area 2 is provided with a first cleaning mechanism and a second cleaning mechanism in sequence along the wheel's forward direction. The first cleaning mechanism and the second cleaning mechanism are arranged alternately to support one side of the wheel while cleaning the other side of the wheel.

[0041] This application sequentially arranges a cleaning zone 2, a wiping zone 3, and a collection zone 4 in the housing 1. The wheels are cleaned through the cleaning zone 2, removing water from the wheels to prevent water from contaminating the ground. The wastewater after cleaning is collected in the collection zone 4 for easy discharge. By sequentially arranging a first cleaning mechanism and a second cleaning mechanism along the wheel's forward direction in the cleaning zone 2, and by staggering the first and second cleaning mechanisms, the first cleaning mechanism can support one side of the wheel, so that the cleaning component 22 is not under stress, which facilitates cleaning one side of the wheel, improves cleaning efficiency, and reduces the power requirements of the drive mechanism. Similarly, the second cleaning mechanism can clean the other side of the wheel, thereby completing the cleaning of the entire wheel.

[0042] In some embodiments of this application, see Figures 2-5The first cleaning mechanism and the second cleaning mechanism have the same structure, both including a motor 21 and multiple cleaning components 22 that are connected to the motor 21 for transmission. The cleaning component 22 includes a timing belt 221 and a support component disposed on the side of the timing belt 221. A brush 222 is disposed on the outer side of the timing belt 221 and along the direction of wheel travel. The brush 222 in adjacent cleaning components 22 is located on the same straight line as the support component.

[0043] See Figures 11-13 The existing AGV vehicle 7 generally includes two side wheels 71 and four intermediate wheels 72. Taking one of the intermediate wheels 72 of the AGV vehicle 7 as an example, this intermediate wheel 72 consists of two wheels. When passing through the first cleaning mechanism, the brush 222 contacts the left wheel and cleans the left wheel, while the support component supports the right wheel. When passing through the second cleaning mechanism, the brush 222 contacts the right wheel and cleans the right wheel, while the support component supports the left wheel. The cleaning principle of the other wheels is the same and will not be described in detail. By supporting and cleaning both sides of the wheel in sequence, the brush 222 is not subjected to excessive pressure, thus improving the cleaning effect and reducing the power requirement of the motor 21 that drives the brush 222 to rotate.

[0044] In some embodiments of this application, see Figure 5 The support components include a main load-bearing component 223 and multiple distributed load-bearing components 224. The distributed load-bearing components 224 are evenly arranged at the bottom of the main load-bearing component 223 and are fixedly connected to the bottom of the box body 1.

[0045] The main load-bearing component 223 supports the weight of the wheel, preventing the wheel's weight from being transmitted to the brush 222. The distributed load-bearing component 224 distributes the force received by the main load-bearing component 223 to the bottom of the box 1, making the box 1 evenly stressed. Furthermore, there are gaps between adjacent distributed load-bearing components 224, which facilitates cleaning the inside of the box 1.

[0046] In some embodiments of this application, see Figure 5 There are two main load-bearing components 223, which are respectively set on both sides of the synchronous belt 221. Each main load-bearing component 223 is provided with three distributed load-bearing components 224 below it, and the three distributed load-bearing components 224 are respectively set in the middle and at both ends of the main load-bearing component 223.

[0047] In some embodiments of this application, see Figure 5 The cleaning assembly 22 also includes a drive wheel 228 and a driven wheel 229. A timing belt 221 is sleeved on the outside of the drive wheel 228 and the driven wheel 229. The drive wheel 228 is connected to the motor 21 for transmission. The driven wheel 229 is rotatably connected to a driven wheel mounting seat 225. Both ends of the driven wheel mounting seat 225 are connected to timing belt tensioning assemblies.

[0048] The motor 21 can drive the drive wheel 228 to rotate, and the drive wheel 228 drives the timing belt 221 to rotate, thereby driving the brush 222 connected to the timing belt 221 to rotate, thus cleaning the wheel. The timing belt 221 can be tensioned by the timing belt tensioning assembly to prevent the timing belt 221 from sagging.

[0049] In some embodiments of this application, see Figure 5 The synchronous belt tensioning assembly includes an adjusting seat 226 and an adjusting bolt 227. The support assembly is provided with a sliding groove. The driven wheel mounting seat 225 is slidably disposed in the sliding groove. The adjusting seat 226 is fixedly connected to the support assembly. The adjusting bolt 227 is threadedly connected to the adjusting seat 226. One end of the adjusting bolt 227 passes through the adjusting seat 226 and is rotatably connected to the driven wheel mounting seat 225.

[0050] By rotating the adjusting bolt 227, the driven wheel mounting seat 225 can be driven to slide along the slide groove, thereby adjusting the tension of the timing belt 221 and preventing the timing belt 221 from sagging.

[0051] In some embodiments of this application, a baffle (not shown) is provided at the bottom of the timing belt 221 to support the timing belt 221 and further prevent the timing belt 221 from sagging.

[0052] In some embodiments of this application, see Figure 5 The cleaning assembly 22 also includes a water filter wheel 230. The two ends of the water filter wheel 230 are rotatably connected to the support assembly. The side wall of the water filter wheel 230 abuts against the brush 222. The water filter wheel 230 is located on the side close to the wiping area 3. The movement direction of the brush 222 is opposite to the movement direction of the wheel.

[0053] The brush 222 located at the bottom contacts the water at the bottom of the housing 1 to absorb water. If too much water is absorbed by the brush 222, it is easy to splash water out. By placing the water filter wheel 230 on the side close to the wiping area 3, after the brush 222 absorbs water, the excess water is first squeezed out by the water filter wheel 230, thus avoiding the problem of water splashing during cleaning. The direction of movement of the brush 222 is opposite to the direction of travel of the wheel, and the relative speed between the wheel and the brush 222 is higher, which can improve the cleaning effect on the wheel.

[0054] In some embodiments of this application, see Figure 6 and Figure 7 The inner side of the timing belt 221 is provided with multiple clearance grooves 2211 along its length direction. The brush 222 is connected to the timing belt 221 by a stitch, and the stitch is located in the clearance groove 2211.

[0055] By attaching a brush 222 to the surface of the timing belt 221 and connecting it to the timing belt 221 through perforation and stitching, two clearance grooves 2211 are provided on the inner side of the timing belt 221 to prevent wear on the stitching by the driving pulley 228 and the driven pulley 229. Stitching is then performed at these two clearance grooves. This connection method is cost-effective. Furthermore, while the timing belt 221 stretches when bending, the brush 222, being a plastic material, is not easily deformed. The stitching method allows for some deformation space, preventing excessive resistance during bending and reducing the load on the motor 21. Additionally, the brush 222 in this application is made using a weaving process, making it less prone to shedding.

[0056] In some embodiments of this application, see Figures 1-3 The first and second cleaning mechanisms each have four cleaning components 22 arranged side by side. The motor 21 is connected to the drive shaft 23, and the drive shaft 23 is sequentially connected to the four cleaning components 22.

[0057] Specifically, the drive shaft 23 passes through the four drive wheels 228 in sequence and is fixedly connected to the four drive wheels 228. Thus, a motor 21 can simultaneously drive the four synchronous belts 221 to rotate, thereby cleaning the four wheels at the same time and improving cleaning efficiency.

[0058] In some other embodiments of this application, the number of cleaning components 22 in each cleaning mechanism may also be other, which can be determined according to the number of lateral wheels of the AGV vehicle 7, and this application does not limit it.

[0059] In some embodiments of this application, see Figures 1-3 A water filter cover 24 is installed on the top of the cleaning area 2. The water filter cover 24 is fixedly connected to the top of the housing 1, and a supporting beam is provided on the top of the housing 1 to support the water filter cover 24. The water filter cover 24 has multiple water filter holes for draining water from the water filter cover 24 into the housing 1. The water filter cover 24 has strip-shaped holes through which a portion of the timing belt 221 and the brush 222 protrudes, thus contacting the wheels to clean them. The main load-bearing component 223 is located below the water filter cover 24 and contacts the water filter cover 24 to support the wheels. The water filter cover 24 also protects the internal structure of the cleaning area 2, improving safety.

[0060] See Figure 3 In some embodiments of this application, guide plates 25 are provided on both sides of the cleaning area 2 to guide the vehicle so that the wheels can accurately press on the support components and brushes 222.

[0061] In some embodiments of this application, see Figure 8 and Figure 9The bottom heights of the cleaning area 2, wiping area 3 and collection area 4 inside the box 1 decrease sequentially. The bottom of the collection area 4 is a slope. The side wall of the box 1 is provided with a water inlet 11 and a drain outlet 12. The water inlet 11 is located at the end of the cleaning area 2 away from the wiping area 3, and the drain outlet 12 is located at the lowest point of the collection area 4.

[0062] This application divides the internal area of ​​the housing 1 into a stepped cleaning zone 2, a wiping zone 3, and a collection zone 4. When the cleaning mechanism is running, the synchronous belt 221 located below moves, causing the cleaning zone 2 to form a downward water flow, discharging the dirt in the cleaning zone 2 to the wiping zone 3. Because there is a step between the cleaning zone 2 and the wiping zone 3, the dirt in the wiping zone 3 cannot flow back, thus the dirt accumulates in the wiping zone 3, making it easy to clean. The water inlet 11 is located above the cleaning zone 2, in the high area of ​​the housing 1, and the drain outlet 12 is located in the collection zone 4, in the lowest position of the housing 1, which facilitates drainage and forms a circulation with the water inlet 11.

[0063] In some embodiments of this application, see Figures 1-3 and Figure 8 The box body 1 has an electrical circuit area 5 and a water circuit area 6 on both sides along the direction of wheel travel. The motor 21 is installed in the electrical circuit area 5. The motor 21 and the cleaning component 22 are sealed to the side wall of the box body 1. The water circuit area 6 is equipped with a sewage pump 61, a water inlet pump 63 and a water storage tank. The sewage pump 61 is connected to the drain outlet 12 through a sewage pipe. The water inlet pump 63 is connected to the water storage tank and the water inlet 11 through pipes.

[0064] The circuit area 5 is used to install electrical equipment and cables. The side wall of the enclosure 1 separates the circuit area 5 from the water-containing area, and a sealing structure (such as a sealing ring) is provided on the side wall of the enclosure 1 to prevent water leakage from causing short circuits in the equipment. In some embodiments of this application, the circuit area 5 is provided with a wire harness concentration area 51, which can concentrate all cables in this area and use a junction box to collect and bring out the cables, facilitating cable connections during equipment installation and disassembly.

[0065] The sewage pump 61 is used to drain the dirt inside the tank 1, the water storage tank 62 is used to store water to ensure the water demand of the tank 1, and the water inlet pump 63 is used to pump water from the water storage tank 62 into the tank 1 for replenishment. The water passage area 6 is equipped with a sewage drain cover 64 that is easy to open, and a sewage drain pipe is placed inside the water passage area 6, so that cleaning and maintenance personnel can easily open the sewage drain cover 64 and take out the sewage drain pipe for sewage discharge.

[0066] In some embodiments of this application, see Figure 3 and Figure 4 Adjacent cleaning components 22 are connected to each other, and the housing 1 is connected to the cleaning components 22 via connecting rods 26. For details, please refer to [link / reference needed]. Figure 4A waist-shaped hole 261 is provided at the connection between the connecting rod 26 and the side wall of the housing 1, and the waist-shaped hole 261 is set in the vertical direction. By connecting the vertically set waist-shaped hole 261 to the side wall of the housing 1, the side wall can be prevented from deforming under force, so that the entire load is applied to the bottom of the housing 1.

[0067] In some embodiments of this application, a liquid level sensor (not shown) is provided inside the housing 1, and the water inlet pump 63 is electrically connected to the liquid level sensor.

[0068] The water level inside the tank 1 can be detected by the liquid level sensor (the water level inside the tank 1 should generally be just enough to submerge the lower part of the synchronous belt 221). When the water level is lower than the set water level, the liquid level sensor sends a signal to the water inlet pump 63, which starts and pumps water from the water storage tank 62 into the tank 1. When the water level exceeds the set water level, the liquid level sensor sends a signal to the water inlet pump 63, which stops working.

[0069] In some embodiments of this application, see Figure 10 The wiping area 3 is equipped with a wiping assembly, which includes a mounting plate 31 and a water-absorbing component 32. The mounting plate 31 is fixedly connected to the housing 1, and the water-absorbing component 32 is detachably connected to the mounting plate 31.

[0070] The water-absorbing component 32 is installed in the area where the wheels pass. It can absorb the water remaining on the wheels, thus preventing the wheels from carrying water and polluting the ground. The water-absorbing component 32 is detachable and easy to replace. When the water-absorbing component 32 absorbs too much water, it can be removed and replaced.

[0071] In some embodiments of this application, the water-absorbing element 32 is a sponge. Optionally, the water-absorbing element 32 can also be a cloth or other materials with strong water absorption capacity. This application does not limit this.

[0072] In some embodiments of this application, the bottom of the housing 1 is provided with reinforcing ribs. Specifically, the reinforcing ribs are arranged in two rows along the length of the support components in the main load-bearing area of ​​the housing 1 (i.e., the area below the support components), and sparsely arranged in other areas of the housing 1. Since the equipment needs to bear a load of about 1 ton and the overall weight of the equipment needs to be controlled, the load-bearing capacity of the housing 1 can be improved by setting reinforcing ribs.

[0073] See Figure 14 In some embodiments of this application, the front and rear ends of the housing 1 are respectively provided with an uphill component 8 and a downhill component 9. The uphill component 8 and the downhill component 9 facilitate the AGV vehicle 7 to get on and off the cleaning equipment.

[0074] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
