Abstract
Description
Technical Field
[0001] This utility model relates to the field of floor trailer technology, specifically to a rear-steering floor trailer. 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 mopping device is located at the rear of the vehicle. The dirt on the ground is first crushed by the wheels, resulting in a more tightly bound dirt layer, which is detrimental to subsequent mopping operations. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is:
[0005] 1. Design a mopping cart with a front-mounted mopping mechanism, so that the mopping mechanism cleans the floor surface first, and then the drive wheel or steering wheel passes over it, reducing the contact between dirt and the drive wheel or steering wheel.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A rear-steering mopping vehicle includes a vehicle body, mopping components, a clean water tank, and a wastewater tank;
[0008] The vehicle body includes a frame, a steering assembly, a steering rear wheel, a drive front wheel, and a drive unit. The clean water tank and the wastewater tank are both mounted on the frame. The steering rear wheel and the drive front wheel are both mounted below the frame. The drive unit is connected to the drive front 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 steering rear wheel relative to the frame. The mopping direction of the mopping assembly is perpendicular to the vehicle's travel direction.
[0009] A rear seat is also provided on one end of the vehicle frame near the steering assembly;
[0010] The mopping component is located at the end of the vehicle frame away from the steering component.
[0011] This design, employing a rear-mounted steering assembly and a rear-seat configuration, provides ample space on the frame to install the front-mounted mopping assembly, while maintaining overall stability of the mopping vehicle's center of gravity. When the mopping vehicle is moving forward, the mopping assembly first cleans the surface; any dirt that cannot be cleaned during mopping is pushed to one side of the vehicle, awaiting removal by a dedicated sweeper or manual labor. The operator, seated in the rear seat, controls the mopping vehicle's direction of travel by maneuvering the steering assembly.
[0012] Optionally, only one steering rear wheel may be located under the frame.
[0013] Specifically, there are two drive front wheels, forming a three-wheel structure with a single steering rear wheel. The single steering rear wheel design is easier to control, allowing for the use of simpler steering components and helping to reduce the overall space occupied by the mop.

[0015] 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.
[0016] 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.
[0017] 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.
[0018] 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.
[0019] 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.
[0020] Preferably, the output end of the drive motor assembly is connected to one end of the fourth roller.
[0021] 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.
[0022] 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.
[0023] Preferably, the air outlet is directed towards the mop belt inside the water collection tank.
[0024] 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.
[0025] The beneficial technical effects of this utility model are as follows: by adopting a rear-mounted steering component and a rear-mounted seat design, sufficient space is provided for the frame to install the front-mounted mopping component, while maintaining the overall center of gravity of the mopping vehicle. When the mopping vehicle is moving forward, the mopping component first cleans the ground surface; any dirt that cannot be cleaned can be pushed to one side of the vehicle body, awaiting cleaning by a dedicated sweeper or manual labor. The operator, seated on the rear seat, controls the direction of travel of the mopping vehicle by operating the steering component. Attached Figure Description

[0031] Reference Figure 1-3 As shown, a rear-steering mopping vehicle includes a vehicle body, a mopping assembly, a clean water tank, and a wastewater tank.
[0032] A rear-steering mopping vehicle includes a vehicle body, a mopping assembly 1, a clean water tank 3, and a wastewater tank 4.
[0033] The vehicle body includes a frame 2, a steering assembly 5, a rear steering wheel 6, two front drive wheels 7, and a drive unit. A clean water tank 3 and a wastewater tank 4 are both mounted on the frame 2. The rear steering wheel 6 and the front drive wheels 7 are both mounted below the frame 2. The drive unit is connected to the front drive wheels 7. A mopping assembly 1 is mounted below the frame 2. The clean water tank 3 and the wastewater tank 4 are both connected to the mopping assembly 1. The steering assembly 5 is mounted on the frame 2 and is used to control the angle of the rear steering wheel 6 relative to the frame 2. The mopping direction of the mopping assembly 1 is perpendicular to the vehicle's direction of travel. A rear seat 8 is also provided on the end of the frame 2 near the steering assembly 5. A foot pedal 9 is also provided at the connection between the rear seat 8 and the frame 2. The mopping assembly 1 is located on the end of the frame 2 furthest from the steering assembly 5. The frame 2 is also equipped with a hot air drying assembly, including a hot air gun 10, an air outlet 11, and a mounting bracket 12. The hot air gun 10 is connected to the air outlet 11, and the mounting bracket 12 is used to fix the hot air gun 10 to the frame 2. The air outlet 11 is directed towards the mop belt 22 in the water collection tank 20.
[0034] The hot air drying unit is mainly used to dry the mop belt 22 after the wastewater in the water collection tank 20 is emptied, thereby reducing the emission of odors and the mold growth of the mop belt.
[0035] The mopping assembly 1 includes a frame 13, a drive motor assembly 14, a driven roller assembly, and a mop belt 22. The frame 13 is mounted on a vehicle frame 2 via a lifting device 21. The mop belt 22 is driven by the driven roller assembly to generate relative movement with respect to the ground surface. The drive motor assembly 14 is mounted on the frame 13, and its output end is connected to one end of a fourth roller 18. A water collection tank 20 is provided on the frame 13. The driven roller assembly includes a first roller 15, a second roller 16, a third roller 17, a fourth roller 18, a fifth roller, and a wringer 19. The mop belt 22 passes sequentially over the surfaces of the first roller 15, the second roller 16, the third roller 17, the fourth roller 18, the fifth roller, and the wringer 19, and is connected end to end. The third roller 17 is located within the water collection tank 20, and the portion of the mop belt 22 closest to the third roller 17 is located below the third roller 17. The aforementioned water collection tank 20 is connected to the clean water tank 3 and the wastewater tank 4. The clean water tank 3 controls the liquid to enter the water collection tank 20 through a switch valve, and controls the liquid to enter the wastewater tank 4 from the water collection tank 20 through a switch valve and a water pump. The first roller 15, the second roller 16, the fourth roller 18, and the fifth roller are provided with anti-detachment grooves, and the corresponding surface of the mop belt 22 is provided with corresponding anti-detachment protrusions.
[0036] The lifting device 21 is used to control the approximate height of the mopping assembly 1 relative to the ground surface. When in use, the mopping assembly 1 is lowered so that the mop belt 22 at its bottom contacts the ground surface. Then, the drive motor assembly 14 drives the roller in the driven roller assembly. The roller drives the mop belt 22 to rub against the ground surface and remove dirt, thus producing a mopping effect.
[0037] This solution, by adopting a rear-mounted steering component 5 and a rear-mounted rear seat 8, provides sufficient space for the frame 2 to install the front-mounted mopping component 1, while keeping the overall center of gravity of the mopping vehicle stable.
[0038] When the mopping cart is moving forward, the mopping component 1 first cleans the floor surface. Dirt that cannot be cleaned during mopping can be pushed to one side of the cart, waiting for a dedicated sweeper or manual cleaning. The operator sits on the rear seat 8 and controls the direction of travel of the mopping cart by operating the steering component 5.
[0039] In this design, there are two front drive wheels 7, which together with a single steering rear wheel 6 form a three-wheel structure. The single steering rear wheel design is easier to control, allowing for the use of a simpler steering assembly 5, which helps to reduce the overall space occupied by the mop.
