Description

Technical Field

[0001] This utility model belongs to the field of automatic cleaning, specifically relating to a mobile automatic cleaning device for property work areas. Background Technology

[0002] The automatic cleaning device for property management work areas is an intelligent cleaning equipment designed specifically for public areas such as residential communities and office buildings. It solves the problems of low efficiency, high cost, and uneven cleaning quality of manual cleaning. It can be adapted to complex scenarios such as underground garages, corridors, and outdoor walkways, achieving a cleaning effect of "less intervention, high efficiency, and full coverage".

[0003] In existing technologies, property management work areas encompass diverse scenarios such as underground parking garages, corridors, elevator lobbies, and outdoor walkways. Existing equipment often suffers from a one-size-fits-all problem, using a single cleaning device to clean all areas. However, in practical use, uneven terrain such as varying elevations in underground parking garages and gravel paths on outdoor walkways can cause cleaning equipment with fixed chassis heights to get stuck or miss areas. Furthermore, when working at the edges of steps, uneven gaps between paving stones, and the junction of lawns and roads, a single suction structure is insufficient to remove scattered trash and fine dust, easily leading to missed areas. Therefore, this utility model proposes a mobile automatic cleaning device for property management work areas to solve the problems existing in the prior art. Utility Model Content

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-8This utility model provides an embodiment: a mobile automatic cleaning device for a property work area, including a chassis 3, a first connecting frame 11, a second connecting frame 23, a hydraulic suspension 19, a vacuum head 4, and a cleaning brush head 5. Two sets of brush head frames 8 are symmetrically distributed at the front and rear ends of the chassis 3. A first drive motor 9 is mounted on the upper end of each brush head frame 8. The output end of the first drive motor 9 passes through the brush head frame 8 and is fixedly connected to the cleaning brush head 5. The vacuum head 4 is connected to the center of the left and right ends of the chassis 3 via two sets of symmetrically distributed fixing frames 25. Two sets of symmetrically distributed mounting frames 7 are fixed to the left and right ends of the chassis 3. A first connecting frame 4 is fixedly connected within each mounting frame 7. The frame 11 has a first extension frame 12 fixedly connected to both ends of the first connecting frame 11. A drive shaft 14 is rotatably mounted on the first connecting frame 11, and a drive wheel 16 is fixedly connected to one end of the drive shaft 14 near the chassis 3. A movable wheel 6 is rotatably mounted on the second connecting frame 23. A wheel frame 17 is fixedly connected to one end of the movable wheel 6 near the chassis 3 and passing through the second connecting frame 23. One end of a universal joint 20 is hinged to the wheel frame 17. One end of a first connecting rod 18 and one end of a second connecting rod 21 are respectively hinged to the upper and lower ends of the second connecting frame 23. A second extension frame 22 is fixedly connected to the center of both ends of the second connecting rod 21. The output end of the hydraulic suspension 19 is hinged to the second extension frame 22.

[0026] Through the linkage structure of hydraulic suspension 19 with first link 18 and second link 21, the height of chassis 3 can be adjusted in real time according to the ground elevation difference. This ensures the contact between the sweeping brush head 5 and the vacuum head 4 and the ground, while avoiding equipment jamming or component damage. At the same time, the four sets of sweeping brush heads 5 are distributed on the front and rear sides of the vacuum head 4, forming a working logic of first gathering and then vacuuming, which improves the effect and efficiency of cleaning scattered garbage and fine dust, and further enhances the cleaning efficiency and cleanliness of the device.

[0027] Please see Figures 3-5In this embodiment, the upper end of the chassis 3 has two sets of motor slots 10 symmetrically distributed front and rear. A second drive motor 15 is installed in each motor slot 10. The output end of the second drive motor 15 is connected to the end of the transmission shaft 14 near the chassis 3. The symmetrically distributed motor slots 10 allow the weight of the two sets of second drive motors 15 to be evenly distributed on the chassis 3, preventing uneven weight distribution that could cause the equipment to tilt. Simultaneously, the direct connection of the motors to the near end of the transmission shaft 14 shortens the power transmission path, reduces power loss, and makes the rotational speed of the transmission shaft 14 more stable when driving the moving wheel 6, preventing jamming. The other ends of the first connecting rod 18 and the second connecting rod 21 are hinged to the upper and lower ends of the first connecting frame 11. The step belts 13 are respectively fitted onto two sets of symmetrically distributed drive wheels 16. The connecting rods are hinged to the connecting frame, which can adapt to the bumps of the equipment on uneven roads, reduce the wear of rigid connections, and extend the service life of components. The two sets of synchronous belts 13 are respectively fitted onto the symmetrically distributed drive wheels 16, ensuring that the speed of the drive shafts 14 and the moving wheels 6 on the left and right sides is completely consistent, avoiding the equipment from running off-center due to one side being faster and the other side being slower. The other end of the universal joint 20 is fixed to the end of the drive shaft 14 away from the chassis 3. The tail end of the hydraulic suspension 19 is hinged to the first extension frame 12. The universal joint 20 is connected to the far end of the drive shaft 14, which allows the moving wheels 6 to freely adjust their angle when turning, improving the flexibility of the equipment when turning, especially suitable for operation in narrow spaces.

[0028] Please see Figures 3-6 In this embodiment, a housing 1 is installed around the upper edge of the chassis 3, and an automatic control system 2 is installed on the upper end of the housing 1. A negative pressure vacuum cleaner 24 is installed at the center of the upper end of the chassis 3. Two sets of vacuum heads 4 are connected to the negative pressure vacuum cleaner 24 through two sets of pipes penetrating the housing 1. The housing 1 is installed around the edge of the chassis 3 to isolate external dust, water stains, or debris, protecting core components such as the motor and drive shaft 14 inside the chassis 3 and reducing malfunctions. At the same time, the automatic control system 2 at the top can directly control the operation of the equipment without the need for additional external control. The device improves ease of operation. Anti-collision blocks 26 are fixed to the front and rear edges of the outer shell 1, and two sets of mudguards 27 are fixed to the left and right edges of the outer shell 1, which are symmetrically distributed. The anti-collision blocks 26 at the front and rear ends can absorb the impact force when the equipment accidentally hits the wall or obstacle, so as to prevent the outer shell 1 from being directly deformed by the force, thereby protecting the internal components. The mudguards 27 at the left and right ends correspond to the moving wheels 6 and can block the mud and sewage kicked up when the moving wheels 6 rotate, preventing the stains from splashing onto the outer shell 1 or the ground, keeping the equipment clean, and avoiding pollution of the working environment.

[0029] Please see Figures 3-7In this embodiment, the universal joint 20 is located between the two sets of hydraulic suspensions 19 and the first link 18 and the second link 21. The moving wheel 6 corresponds to the mudguard 27. A battery is installed on the upper inner wall of the outer casing 1. The universal joint 20 is located between the hydraulic suspensions 19 and the link, which can make full use of the gap between the components, avoid mutual interference between the parts, make the internal structure of the chassis 3 more compact, and save space.

[0030] The automatic control system 2 in this new practical application is based on the existing system. Its core is to achieve "autonomous operation + clean management and control", and its main functions are concentrated in three aspects:

[0031] Path planning: Using a preset map or simple sensors (such as infrared and ultrasonic waves), basic path travel such as straight lines and fixed-point round trips can be achieved. Some high-end devices can use GPS positioning to avoid fixed obstacles (such as streetlights and green belts).

[0032] Device linkage: It can synchronously control the start and stop of cleaning components. For example, when driving the cleaning brush head 5 to rotate, the negative pressure vacuum cleaner 24 is automatically turned on to avoid a single component running idle and wasting energy. At the same time, it can monitor the battery power and trigger the automatic recharging function when the battery is low.

[0033] Basic status monitoring: Real-time collection of data such as motor speed and suction pressure. If problems such as brush head jamming or vacuum cleaner malfunction occur, an alarm signal will be sent via indicator light or APP. These are all existing technologies, and this is written to meet the requirement of full disclosure.

[0034] The workflow logic diagram of this utility model is as follows: Figure 8 As shown, its specific implementation method is as follows:

[0035] After the equipment is started, the automatic control system 2 receives the command and the battery supplies power to each component. If it encounters uneven ground, the hydraulic suspension 19 will extend and retract according to the terrain feedback. By pushing the second extension frame 22, it drives the second link 21 and the first link 18 to rotate, and finally adjusts the relative height between the moving wheel 6 and the chassis 3 to ensure that the chassis 3 is stable and the cleaning brush head 5 and the vacuum head 4 are in contact with the ground.

[0036] Next, the second drive motor 15 starts and drives the drive wheel 16 to rotate through the drive shaft 14. The drive wheel 16 achieves multi-wheel synchronization through the synchronous belt 13, and then transmits power to the moving wheel 6 through the universal joint 20, driving the equipment to move along the preset path.

[0037] When encountering trash on the way, the first drive motor 9 drives the cleaning brush head 5 to rotate at high speed. The four sets of cleaning brush heads 5 distributed on the front and back sides of the vacuum head 4 will concentrate the trash on the ground towards the center of the equipment. At the same time, the negative pressure vacuum cleaner 24 is started, generating negative pressure through the pipe. The vacuum head 4 sucks the concentrated trash into the equipment, completing the complete cleaning action of "sweeping first, then gathering, and then vacuuming".

[0038] During movement, the anti-collision blocks 26 at the front and rear of the outer shell 1 prevent the equipment from being damaged by collision, the left and right mudguards 27 prevent mud and sand from splashing and contaminating the cleaned area, and the automatic control system 2 can adjust the cleaning path and component operating status in real time.

[0039] Through the above steps, the four sets of cleaning brush heads 5 directionally gather the garbage, avoiding the dust leakage caused by the garbage being scattered. Fine dust and blocky garbage can be processed simultaneously. The hydraulic suspension 19 adjustment function breaks through the limitations of traditional equipment on flat ground, and can be used in various scenarios such as walkways, lawn edges, and garage ramps in property parks. It solves the problem that existing automatic cleaning robots are difficult to adapt to rugged terrain and have limited cleaning capabilities when used to clean property industrial areas.

[0040] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
