Description

Technical Field

[0001] This utility model relates to the field of floor cleaning vehicle technology, specifically to a three-wheeled floor cleaning vehicle. Background Technology

[0002] Floor cleaning vehicles are commonly used for cleaning roads in large shopping malls, factories, and company premises. In existing technology, floor cleaning vehicles are generally manually driven, such as the road sweeper and floor cleaning vehicle published in Chinese Patent Application Publication No. CN108691290B on May 12, 2020, which consists of three parts: a sweeper, a large waste sweeping device, a small waste sweeping device, and a mopping device. This invention utilizes sweeping rollers to sweep the floor, a conveyor belt to transport waste, and mopping rollers to mop the floor, and also automatically cleans the mopping rollers.

[0003] In this design, the sweeping direction of the mopping mechanism is parallel to the vehicle's direction of travel. As dirt is swept into the mopping device, it tends to accumulate there, affecting the mopping effect. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is:

[0005] 1. Design a miniaturized three-wheeled mopping vehicle that enables the miniaturized mopping components to effectively clean the road surface and push unabsorbed surface dirt to one side during mopping to prevent it from affecting the mopping effect.

[0006] 2. A miniaturized three-wheeled washing trailer structure is provided, in which the brush assembly first peels off the dirt attached to the ground, and then the mopping assembly absorbs and collects the dirt from the ground.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a three-wheeled washing trailer, comprising a vehicle body, a mopping assembly, a clean water tank, a brush assembly, and a wastewater tank. The vehicle body includes a frame, a steering assembly, a front steering wheel, a rear driving wheel, and a drive unit. The clean water tank and the wastewater tank are both mounted on the frame. The front steering wheel and the rear driving wheel are sequentially mounted below the frame. The drive unit is connected to the rear driving wheel. The mopping assembly is mounted below the frame. The clean water tank and the wastewater tank are both connected to the mopping assembly. The steering assembly is mounted on the frame and is used to control the angle of the front steering wheel relative to the frame. The mopping direction of the mopping assembly is perpendicular to the vehicle's travel direction. The brush assembly is mounted below the frame and is located between the front steering wheel and the rear driving wheel. The mopping assembly is located behind the brush assembly.

[0008] This solution ensures that dirt that cannot be collected during mopping is pushed to one side of the vehicle by aligning the mopping component's mopping direction (including but not limited to the friction direction between the roller and the ground, and the friction direction between the mop and the ground) perpendicular to the vehicle's direction of travel. This allows the sweeping component or a dedicated sweeper to clean up any dirt that cannot be collected during mopping. The front-mounted brush assembly effectively utilizes the space under the vehicle and removes surface dirt before mopping, allowing the mopping component behind it to absorb and collect the dirt.

[0009] Optionally, the mopping assembly includes a frame, a drive motor assembly, a driven roller assembly, and a mop belt. The frame is mounted on the vehicle frame via a lifting device. The mop belt is driven by the driven roller assembly to generate relative movement with respect to the ground surface. The drive motor assembly is mounted on the frame, and the output end of the drive motor assembly is connected to the driven roller assembly.

[0010] The lifting device controls the approximate height of the mopping assembly relative to the floor surface. During use, the mopping assembly is lowered so that the mop belt at its bottom contacts the floor. Then, the drive motor assembly drives the rollers in the driven roller assembly, which in turn cause the mop belt to rub against the floor, removing dirt and producing a mopping effect.

[0011] Optionally, the frame is provided with a water collection tank, and the driven roller assembly includes a first roller, a second roller, a third roller, a fourth roller, a fifth roller, and a squeezing roller. The mop belt passes sequentially between the surfaces of the first roller, the second roller, the third roller, the fourth roller, the fifth roller, and the squeezing roller, and is connected end to end. The third roller is located in the water collection tank, and the portion of the mop belt near the third roller is located below the third roller.

[0012] The aforementioned water collection tank is connected to the clean water tank and the wastewater tank. The clean water tank controls the flow of liquid into the water collection tank via a switch valve, and the switch valve and water pump control the flow of liquid from the water collection tank into the wastewater tank. The first, second, fourth, and fifth rollers are provided with anti-detachment grooves, and the corresponding surfaces of the mop belt are provided with corresponding anti-detachment protrusions.

[0013] Optionally, the output end of the drive motor assembly is connected to the first roller, the second roller, the fourth roller, or the fifth roller.

[0014] Preferably, the output end of the drive motor assembly is connected to one end of the fourth roller.

[0015] The fourth roller is located on the top of the mopping assembly, with enough space to install the motor and transmission components in the drive motor assembly.

[0016] Optionally, the vehicle frame is also equipped with a hot air drying assembly, including a hot air gun, an air outlet, and a fixing bracket. The hot air gun is connected to the air outlet, and the fixing bracket is used to fix the hot air gun to the vehicle frame. The air outlet has an air outlet direction corresponding to the mop belt.

[0017] Preferably, the air outlet is directed towards the mop belt inside the water collection tank.

[0018] The hot air drying unit is mainly used to dry the mop belt after the wastewater collection tank is emptied, reducing odor emission and mold growth on the mop belt.

[0019] The beneficial technical effects of this utility model are: by designing a small and integrated mopping component, it can be directly installed at the lower rear of the vehicle body, with its mopping direction perpendicular to the vehicle's direction of travel, so that dirt that cannot be collected during mopping can be pushed to the side of the vehicle body, waiting to be swept by the sweeping component or a special sweeping vehicle when the next wheel passes by.

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0026] Reference Figure 1-4 As shown, it includes a vehicle body, a mopping assembly 7, a clean water tank 5, and a wastewater tank 17.

[0027] The vehicle body includes a frame 1, a steering assembly 2, a front steering wheel 3, a rear drive wheel 4, a brush assembly 6, a mopping assembly 7, and a drive unit. A clean water tank 5 and a wastewater tank 17 are both mounted on the frame 1. The front steering wheel 3 and the rear drive wheel 4 are sequentially mounted below the frame 1. The drive unit includes a motor and a battery, with the motor's output connected to the rear drive wheel 4. The mopping assembly 7 is mounted below the frame 1, and both the clean water tank 5 and the wastewater tank 17 are connected to it. The frame 1 includes a front panel and a rear panel, with a certain height difference between them. The brush assembly 6 is mounted below the front panel. The height design of the rear panel relative to the ground provides ample space for the rear drive wheel 4, the drive unit, and the mopping assembly 7 at the rear of the vehicle.

[0028] Reference Figure 3 As shown, the brush assembly 6 includes a brush holder 23, a brush 24, and a brush motor 25 for driving the brush 24 to rotate. One end of the brush holder 23 is connected to the frame 1, and the other end is connected to the brush 24. The brush 24 rotates on the brush holder 23 under the control of the brush motor 25. The brush 24, driven by the brush motor 25, peels off dirt adhering to the ground surface. The specific structure of the brush holder 23 is shown in the figure, including two pairs of connecting rods and corresponding mounting brackets. The mounting brackets are fixed to the brush holder 23 by bolts. One end of the connecting rod is rotatably connected to the front plate, and the other end of the connecting rod is rotatably connected to the mounting bracket. This design ensures that the brush assembly has a certain degree of self-adaptation when encountering uneven ground surfaces, maintaining a uniform cleaning force.

[0029] Reference Figure 1 The position of the brush motor 25 is visible. The motor is located below the rear plate. The height difference between the rear plate and the front plate effectively provides the brush motor 25 with room to move, preventing the brush motor 25 from colliding with the frame 1.

[0030] The steering assembly 2 is mounted on the frame 1. The steering assembly 2 is used to control the angle of the steering front wheel 3 relative to the frame 1. The dragging direction of the dragging assembly 7 is perpendicular to the vehicle's travel direction.

[0031] The mopping assembly 7 includes a frame 8, a drive motor assembly 9, a driven roller assembly, and a mop belt 11. The frame 8 is mounted on the vehicle frame 1 via a lifting device 10. The mop belt 11 is driven by the driven roller assembly to generate relative movement with the ground surface. The drive motor assembly 9 is mounted on the frame 8, and the output end of the drive motor assembly 9 is connected to the driven roller assembly.

[0032] A water collection tank 12 is provided on the frame 8. 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 sequentially over the surfaces of the first roller 13, the second roller 14, the third roller 15, the fourth roller 16, the fifth roller, and the wringing roller 18, and is connected end to end. The third roller 15 is located inside the water collection tank 12, and the portion of the mop belt 11 near the third roller 15 is located below the third roller 15. The output end of the drive motor assembly 9 is connected to one end of the fourth roller 16. Due to space limitations, only the output end of the drive motor assembly 9 and the belt are shown in the figure.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.
