[0026] Embodiment 1

[0027] Referring to Figures 1-3 As shown in the drawings, a three-wheeled floor mopping vehicle includes a vehicle body, a floor mopping assembly 7, a clean water tank 5 and a dirty water tank 17.

[0028] The vehicle body includes a vehicle frame 1, a direction steering assembly 2, a steering front wheel 3, a driving rear wheel 4 and a driving device. The clean water tank 5 and the dirty water tank 17 are both mounted on the vehicle frame 1. The steering front wheel 3 and the driving rear wheel 4 are both mounted below the vehicle frame 1 in sequence. The driving device includes a motor and a storage battery. The output end of the motor is connected to the driving rear wheel 4. The floor mopping assembly 7 is mounted below the vehicle frame 1. The clean water tank 5 and the dirty water tank 17 are both connected to the floor mopping assembly 7. A front-mounted clean water tank 6 is also mounted on the vehicle frame 1 between the steering front wheel 3 and the driving rear wheel 4.

[0029] The direction steering assembly 2 is arranged on the vehicle frame 1. The direction steering assembly 2 is used to control the angle of the steering front wheel 3 relative to the vehicle frame 1. The direction of the floor of the floor mopping assembly 7 is perpendicular to the direction of travel of the vehicle body.

[0030] The floor mopping assembly 7 includes a rack 8, a driving motor assembly 9, a driven roller assembly and a mop belt 11. The rack 8 is mounted on the vehicle frame 1 by a lifting device 10. The mop belt 11 is driven by the driven roller assembly to produce relative motion with the ground surface. The driving motor assembly 9 is mounted on the rack 8. The output end of the driving motor assembly 9 is connected to the driven roller assembly.

[0031] The rack 8 is provided with a water collecting groove 12. The driven roller assembly includes a first roller 13, a second roller 14, a third roller 15, a fourth roller 16, a fifth roller and a wringing roller 18. The mop belt 11 passes through the surfaces of the first roller 13, the second roller 14, the third roller 15, the fourth roller 16 and the fifth roller in sequence, and is connected end to end between the fifth roller and the wringing roller 18. The third roller 15 is located in the water collecting groove 12. The part of the mop belt 11 close to the third roller 15 is located below the third roller 15. The output end of the driving motor assembly 9 is connected to one end of the fourth roller 16. Due to the limitation of the length of the article, only the output end of the driving motor assembly 9 and the belt are shown in the drawings.

[0032] Auxiliary casters 19 are provided at each of the four corners of the frame 8 to limit the distance between the frame 8 and the ground surface, prevent the lifting device 10 from going out of control and causing the mopping component 7 to collide with the ground surface, and provide support for the mopping component 7 during use, reducing the burden on the lifting device 10.

[0033] The aforementioned water collection tank 12 is connected to the clean water tank 5 and the wastewater tank 17. The clean water tank 5 controls the liquid to enter the water collection tank 12 through a switch valve, and controls the liquid to enter the wastewater tank 17 from the water collection tank 12 through a switch valve and a water pump. The first roller 13, the second roller 14, the fourth roller 16, and the fifth roller are provided with anti-detachment grooves, and the corresponding surface of the mop belt 11 is provided with corresponding anti-detachment protrusions.

[0034] The frame 1 is also equipped with a hot air drying assembly, including a hot air gun 20, an air outlet 21 and a fixing bracket 22. The hot air gun 20 is connected to the air outlet 21, and the fixing bracket 22 is used to fix the hot air gun 20 to the frame 1. The air outlet 21 is directed towards the mop belt 11 in the water collection tank 12.

[0035] This solution ensures that dirt that cannot be collected during mopping is pushed to one side of the vehicle by making the mopping direction of the mopping component 7 perpendicular to the vehicle's travel direction, so that it can be cleaned up by the sweeping component or a dedicated sweeping vehicle when the next wheel passes by.

[0036] In use, the lifting device 10 controls the approximate height of the mopping assembly 7 relative to the ground surface, lowering the mopping assembly 7 so that the mop belt 11 at its bottom contacts the ground surface. Then, the drive motor assembly 9 drives the rollers in the driven roller assembly, and the rollers cause the mop belt 11 to rub against the ground surface, carrying away dirt and producing a mopping effect. Dirt that cannot be carried away by the mop belt 11 is pushed to one side and left on the ground surface.

[0037] Example 2 (refer to) Figure 4 As shown, the difference from Embodiment 1 is that, in this embodiment, a pressing mechanism is also provided at the section where the mop belt 11 passes below the water collection tank 12. This pressing mechanism includes several pressing units, each comprising a fixed housing 23, a movable block 24, a spring 25 or other elastic element, and a pressing roller 26. The fixed housing 23 is detachably installed at the bottom of the water collection tank 12. The movable block 24 is slidably connected to the fixed housing 23 in the vertical direction. A spring 25 is provided between the movable block 24 and the fixed housing 23. The pressing roller 26 is rotatably connected to the movable block 24 at the end of the movable block 24 closest to the ground surface. The main function of the pressing mechanism is to press the mop belt 11 firmly onto the ground surface using the pressing roller 26, ensuring sufficient friction between it and the ground surface for better mopping results.
