Detailed Implementation

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] Combination Figure 1 and Figure 2 According to an embodiment of the present utility model, a cleaning robot 100 includes a body, a battery 21, and an electronic control module 22. The body includes a frame 11, which has a front end 11a and a rear end 11b. The battery 21 is disposed on the frame 11 and is disposed on the front end 11a of the frame 11. The electronic control module 22 is disposed on the frame 11 and is electrically connected to the battery 21. In the projection along the vertical direction, at least a portion of the electronic control module 22 overlaps with the battery 21.

[0026] Specifically, the cleaning robot 100 can be a purely electric device. The battery 21 stores energy and powers the cleaning robot 100. The electronic control module 22 controls the vehicle's autonomous driving and the operation of the cleaning mechanism, and is powered by the battery 21. In its vertical projection, at least a portion of the electronic control module 22 overlaps with the battery 21. The electronic control module 22 and the battery 21 can be connected via electrical wiring harnesses. For example, at least a portion of the electronic control module 22 can be positioned above the battery 21 to facilitate wiring between the electronic control module 22 and the battery 21, optimize the distribution of electrical wiring harnesses, facilitate wiring connections, and make the structure of the cleaning robot 100 more compact. It should be noted that at least a portion of the electronic control module 22 is located above the battery 21. The entire electronic control module 22 may be located above the battery 21; or, a portion of the electronic control module 22 may be located above the battery 21, while another portion may be located on the front, rear, left, or right side of the battery 21, so that the battery 21 can be connected to the electronic control module 22 and the battery 21 can supply power to the electronic control module 22.

[0027] The cleaning robot 100 also includes a housing 30, which covers the outside of the frame 11, battery 21 and electronic control module 22, and the housing 30 can protect the frame 11, battery 21 and electronic control module 22.

[0028] The battery 21 is located at the front end 11a of the frame 11, which refers to the part of the frame 11 near the front of the vehicle. Specifically, the battery 21 is closer to the front end of the frame 11 than the rear end of the frame 11. By placing the battery 21 of the cleaning robot 100 at the front, and in the projection along the vertical direction, at least a part of the electronic control module 22 overlaps with the battery 21, the layout of the components of the cleaning robot 100 is optimized, the distribution of the electrical wiring harness is optimized, the wiring harness connection is facilitated, and the overall structure of the cleaning robot 100 is made more compact.

[0029] According to the present utility model embodiment, the cleaning robot 100 has a more compact structure and a smaller and more flexible body by placing the battery 21 in the front and at least a part of the electronic control module 22 overlapping the battery 21 in the vertical direction. This makes the cleaning robot 100 more adaptable to application scenarios such as back streets and alleys. At the same time, the layout of the electrical wiring harness connecting the electronic control module 22 and the battery 21 is optimized to facilitate the connection of the electrical wiring harness.

[0030] For example, the electronic control module 22 may include a chassis electronic control system and an autonomous driving electronic control system. The chassis electronic control system can control the vehicle's driving, the operation of the sweeping disc and the roller sweeper, the operation of the dust removal mechanism, and the dumping of garbage, etc. The autonomous driving electronic control system can control the coordinated operation of sensors such as cameras and radar, collect information such as roads and obstacles, and perform path planning for the vehicle, etc.

[0031] In some embodiments of this utility model, a portion of the electronic control module 22 is located above the battery 21, and another portion is located in front of the battery 21. This makes full use of the space above and in front of the battery 21 and facilitates the wiring harness connection between the battery 21 and the electronic control module 22.

[0032] For example, the electronic control module 22 may include a chassis electronic control system and an autonomous driving electronic control system. The chassis electronic control system may be located above the battery 21, and the autonomous driving electronic control system may be located in front of the battery 21; alternatively, the chassis electronic control system may be located above the battery 21, with a portion of the autonomous driving electronic control system located above the battery 21 and another portion located in front of the battery 21. For instance, the AI ​​computing unit and industrial computer of the autonomous driving control system may be installed in the support unit to address issues such as insufficient internal space and inconvenient maintenance within the cleaning robot 100.

[0033] Combination Figure 2In some embodiments of this utility model, the cleaning robot 100 further includes an electrical bracket 23. The electrical bracket 23 is connected to the frame 11 and can be used to connect and support the electronic control module 22, improving the connection stability of the electronic control module 22. The electrical bracket 23 includes a support portion, at least a portion of which is located above the battery 21. A portion of the electronic control module 22 is installed in the support portion. The electrical bracket 23 is located inside the housing 30 and is spaced apart from the front wall of the housing 30 to form an accommodating space. Specifically, a space for installing the battery 21 is constructed below the support portion. The support portion is used to support the electronic control module 22. In addition, the electrical bracket 23 is spaced apart from the front wall of the housing 30 to form an accommodating space, which can be used to install a portion of the electronic control module 22. By using the battery 21 in the front and setting the electrical bracket 23 to install the electronic control system, the electronic control system is placed on the upper layer and front side of the battery 21, which can save internal space of the cleaning robot 100, optimize the distribution of electrical wiring harnesses, facilitate the connection of electrical wiring harnesses, and make the overall structure of the cleaning robot 100 compact.

[0034] Optionally, the housing 30 may include a housing body 31 and a side door 32. The housing body 31 may have a first opening, and the side door 32 is rotatably connected to the housing 30 to open and close the first opening. The battery 21 is disposed inside the side door 32 and is opposite to the first opening in the left-right direction. By providing the side door 32, it is convenient to inspect and maintain the battery 21, improving the maintenance convenience of the cleaning robot 100. For example, when it is necessary to inspect and maintain the battery 21, the first opening can be opened through the side door 32, avoiding the need to disassemble the housing and increase the maintenance cost of the cleaning robot 100.

[0035] In addition, a portion of the electronic control module 22 is installed in the support section. For example, the chassis electronic control system and part of the autonomous driving electronic control system can be located in the support section, and the chassis electronic control system and part of the autonomous driving electronic control system can be inspected and maintained by opening the side door 32.

[0036] Optionally, the housing 30 may also include a front door 34, and the housing body 31 may have a second opening. The front door 34 is rotatably connected to the housing body 31 to open and close the second opening. A portion of the unmanned driving electronic control system may be located inside the front door 34 and opposite to the second opening in the front-rear direction. For example, when the unmanned driving electronic control system needs to be inspected and maintained, the second opening can be opened through the front door 34 to avoid disassembling the housing 30 and increasing the maintenance cost of the cleaning robot 100.

[0037] Combination Figure 2In some embodiments of this utility model, the body includes a front wheel 12 and a rear wheel 13. The front wheel 12 is connected to the front end 11a of the frame 11, and the rear wheel 13 is connected to the rear end 11b of the frame 11. In the projection along the vertical direction, at least a portion of the battery 21 is located between the front wheel 12 and the rear wheel 13, and the battery 21 is closer to the front wheel 12 than the rear wheel 13. By placing the battery 21 in the front, the space of the front end 11a of the frame 11 is fully utilized, and at least a portion of the electronic control module 22 overlaps with the battery 21 in the vertical direction, thereby improving the space utilization of the cleaning robot 100 and facilitating the connection between the battery 21 and the electronic control module 22.

[0038] Combination Figure 2 In some embodiments of this utility model, the cleaning robot 100 further includes a water tank 40, which is disposed on the frame 11 and at the rear end 11b of the frame 11. The water tank 40 provides a water source for the water spraying dust suppression system of the cleaning robot 100. Exemplarily, during the cleaning process, the cleaning robot 100 sprays water onto the working surface through the water spraying dust suppression system, which can suppress dust pollution and avoid secondary pollution during cleaning.

[0039] The water tank 40 is located at the rear end 11b of the frame 11 to facilitate automatic water replenishment by the cleaning robot 100 via a workstation. It should be noted that the rear end 11b of the frame 11 refers to the portion of the frame 11 closest to the rear of the vehicle; specifically, the water tank 40 is closer to the rear end of the frame 11 than to the front end. For example, the robot includes a front wheel 12 and a rear wheel 13. The front wheel 12 is connected to the front end 11a of the frame 11, and the rear wheel 13 is connected to the rear end 11b of the frame 11. In a vertical projection, the water tank 40 is closer to the rear wheel 13 than to the front wheel 12. By optimizing the layout of the water tank 40, the space utilization of the cleaning robot 100 is improved, resulting in a more compact structure and convenient water replenishment via a workstation.

[0040] For example, the workstation may be equipped with a wireless charging component and a water supply component. The wireless receiving component of the cleaning robot 100 may be located at the rear of the cleaning robot 100 to facilitate the docking of the wireless charging component with the wireless receiving component of the cleaning robot 100. The water spray dust suppression system of the cleaning robot 100 may include a water tank 40, a water tank bracket, a diaphragm pump, a water filter, a water filling box, etc. The water filling box may dock with the water supply component of the workstation for adding water to the water tank 40. The water tank 40 is located at the rear end 11b of the frame 11, facilitating water filling of the water tank 40 via the workstation.

[0041] Combination Figure 2The cleaning robot 100 also includes a drive module 50, which is located below the water tank 40. This makes good use of the vertical space of the cleaning robot 100, resulting in a compact structure. For example, the drive module 50 may include components such as a motor, a drive shaft, and a reducer.

[0042] The drive module 50 can be installed on the frame 11. The body may also include a water tank 40 bracket. The water tank 40 bracket is connected to the frame 11. A space for installing the drive device can be constructed below the water tank 40 bracket. The water tank 40 is supported above the drive module 50 by the water tank 40 bracket, making the overall structure of the cleaning robot 100 compact.

[0043] In some embodiments of this utility model, the housing 30 includes a housing body 31 and a side door 32. The housing body 31 has a first opening, and the side door 32 is rotatably connected to the housing body 31 to open and close the first opening. The water tank 40 and the drive module 50 are located inside the side door 32 and are opposite to the first opening in the left-right direction. By providing the side door 32, it is convenient to inspect and maintain the water tank 40 and the drive module 50, improving the maintenance convenience of the cleaning robot 100. For example, when it is necessary to inspect and maintain the water tank 40 and the drive module 50, the first opening can be opened through the side door 32, avoiding the need to disassemble the housing and increase the maintenance cost of the cleaning robot 100.

[0044] In some embodiments of this utility model, the battery 21 is located inside the side door 32 and is opposite to the first opening in the left-right direction, which facilitates the maintenance of the battery 21 and improves the convenience of maintenance of the cleaning robot 100.

[0045] The housing 30 may include a side door on the left side of the vehicle, or the housing 30 may include a side door on the right side of the vehicle, or the housing 30 may include a left door and a right door, so as to facilitate the inspection and maintenance of the drive module 50 and water tank 40 through the left and right sides of the cleaning robot 100, thereby improving the convenience of maintenance.

[0046] Combination Figure 2 and Figure 3 In some embodiments of this utility model, the body further includes a front wheel 12, which is rotatably connected to the frame 11. The cleaning robot 100 also includes a first sweeping disc 61 and a second sweeping disc 62, which are distributed on the left and right sides of the front wheel 12. In related technologies, the sweeping disc is usually located in front of the front wheel 12, making the overall length of the vehicle too long. The cleaning robot 100 of this utility model, by setting two sweeping discs and distributing them on the left and right sides of the front wheel 12, can reduce the overall length of the vehicle, facilitating the miniaturization design of the cleaning robot 100.

[0047] In addition, the cleaning robot 100 may also include a roller sweeping system, which can be located behind the first sweeping disc 61 and the second sweeping disc 62. By setting up dual sweeping discs in coordination with the roller sweeping system, the cleaning efficiency and cleaning effect of the cleaning robot 100 can be improved, and the problem of missed sweeping can be reduced.

[0048] Optionally, the housing 30 can be installed on the outside of the rotary sweeping system. The housing can protect the rotary sweeping system and prevent the cleaning robot 100 from malfunctioning due to collisions. In addition, the housing 30 may include a side door 32. The rotary sweeping system and the side door 32 can be opposite each other in the left-right direction. By opening the side door 32, the rotary sweeping system can be easily maintained, improving the convenience of maintaining the cleaning robot 100.

[0049] Combination Figures 4 to 6 In some embodiments of this utility model, the machine body further includes: a subframe 14, a lifting mechanism 15, and a garbage bin 16. The subframe 14 is connected to the rear end 11b of the frame 11, and the lifting mechanism 15 is connected to the subframe 14. The garbage bin 16 is connected to the lifting mechanism 15 and is driven by the lifting mechanism 15 to be lifted and retracted. Specifically, the subframe 14 is connected to the frame 11, and the frame 11 can support and fix the subframe 14. The subframe 14 can support the lifting mechanism 15, which facilitates the stable lifting and retraction of the garbage bin 16 by the lifting mechanism 15.

[0050] For example, the trash bin 16 can be used to collect and store the trash cleaned by the cleaning robot 100 during operation. The lifting mechanism 15 can drive the trash bin 16 to move between a lifted position and a retracted position. In the retracted position, the trash bin 16 and the lifting mechanism 15 can be located inside the housing 30. When it is necessary to empty the trash bin 16, the lifting mechanism 15 can drive the trash bin 16 out of the housing 30 for easy emptying. By setting the subframe 14, the lifting mechanism 15 can stably drive the trash bin 16 to lift and retract, improving the working stability of the cleaning robot 100.

[0051] Combination Figure 5 Furthermore, the subframe 14 includes a first support seat 141, a second support seat 142, a crossbeam 143, and a rotating seat 144. The first support seat 141 and the second support seat 142 are distributed in the left-right direction. The crossbeam 143 connects the first support seat 141 and the second support seat 142 respectively. The rotating seat 144 connects the crossbeam 143 and the lifting mechanism 15. Specifically, when the lifting mechanism 15 lifts and retracts the garbage bin 16, the torque of the lifting mechanism 15 can be transmitted to the rotating seat 144. The first support seat 141 and the second support seat 142 can support the crossbeam 143. Thus, the cooperation of the first support seat 141, the second support seat 142, and the crossbeam 143 can improve the support effect of the rotating seat 144 on the lifting mechanism 15, thereby improving the stability of the lifting mechanism 15 in lifting and retracting the garbage bin 16.

[0052] At least one of the first support base 141 and the second support base 142 includes a side beam 1411, a vertical beam 1412, and a diagonal beam 1413. The side beam 1411 extends in the front-rear direction and connects to the frame 11. The vertical beam 1412 extends in the vertical direction, with one end of the vertical beam 1412 connected to the side beam 1411 and the other end connected to the crossbeam 143. The diagonal beam 1413 connects the side beam 1411 and the vertical beam 1412, forming a triangular structure. The side beam 1411 improves the connection stability between the subframe 14 and the frame 11, the vertical beam 1412 supports the crossbeam 143, and the diagonal beam 1413 further enhances the connection stability between the vertical beam 1412 and the side beam 1411, thereby improving the structural strength and stability of the crossbeam 143.

[0053] Additionally, at least one of the first support 141 and the second support 142 may also include a support panel 1414. The support panel 1414 is disposed on the outside of the inclined beam 1413 and connects the inclined beam 1413 and the vertical beam 1412. Specifically, the support panel 1414 is connected to the outside of the triangular structure. The support panel 1414 can reduce the stress concentration problem at the rotating seat 144 and improve the structural strength and stability of the subframe 14. It is understood that the rotating seat 144 needs to support the lifting mechanism 15 to lift and retract the garbage bin 16. Therefore, there will be a stress concentration problem at the location of the rotating seat 144. By setting the support panel 1414 to be connected to the outside of the inclined beam 1413 and connecting the inclined beam 1413 and the vertical beam 1412, the structural strength of the subframe 14 can be improved, thereby effectively supporting the lifting of the garbage bin 16.

[0054] Furthermore, in related technologies, the bottom beam and top beam of the subframe are relatively long, and the top beam is fixed to the water tank bracket. The subframe has three crossbeams on its upper side, and the water tank is placed in front of the drive unit, resulting in a long vehicle body. The excessive length and weight of the subframe also lead to high energy consumption. In this embodiment of the sweeping robot 100, the garbage bin 16 transmits torque to the rotating seat 144 during lifting. The first support seat 141, the second support seat 142, and the crossbeam 143 work together to improve the structural strength of the rotating seat 144, thereby effectively supporting the lifting of the garbage bin 16. The support panel 1414 solves the stress concentration problem at the rotating seat 144, achieving a lightweight design for the subframe 14.

[0055] Optionally, the first support 141 and the second support 142 may each include a vertical beam 1412 and a side beam 1411, and an auxiliary beam 145 may be connected between the two vertical beams 1412 to facilitate the welding and positioning of the subframe 14. After the entire subframe 14 is welded to the frame 11, the auxiliary beam 145 can be disassembled to achieve a lightweight design of the subframe 14 and avoid stress concentration during installation.

[0056] In some embodiments of this utility model, the cleaning robot 100 further includes a wireless receiving component. The wireless receiving component is located at the rear end 11b of the frame 11 and is electrically connected to the battery 21. The wireless receiving component is used to cooperate with the wireless charging component of the workstation for wireless charging. The rear end 11b of the frame 11 refers to the portion of the frame 11 near the rear of the vehicle. Specifically, the wireless receiving component is closer to the rear end of the frame 11 than to the front end.

[0057] For example, the cleaning robot 100 can travel to the workstation via a GPS module. The cleaning robot 100 can reverse and mechanically dock with the workstation, triggering a sensor between the wireless receiver and wireless charging components. The communication module in the workstation's control unit can then receive the charging request signal from the cleaning robot 100 and control the wireless charging component to charge the cleaning robot 100, thus improving the convenience of charging the cleaning robot 100. By placing the wireless receiver at the rear end 11b of the frame 11, it is easier for the cleaning robot 100 to dock and charge with the workstation.

[0058] The wireless charging component and the wireless receiving component can be charged via nuclear magnetic resonance. For example, the wireless charging component may include a wireless transmitting coil, and the wireless receiving component may include a receiving coil. By tuning the wireless charging component (transmitter) and the wireless receiving component (receiver) to the same frequency resonant coil to transmit energy, it is possible to support a greater distance between the wireless charging component and the wireless receiving component, and the charging is safer and more stable. Compared with the electromagnetic induction transmitting coil and receiving coil transmitting energy through magnetic field coupling, the magnetic resonance wireless charging method has lower power supply accuracy requirements, which makes it easier for the cleaning robot 100 to dock with the workstation in the case of unmanned driving, improves the efficiency of wireless charging, and avoids charging difficulties caused by errors in the control accuracy of the cleaning robot 100.

[0059] Furthermore, the housing 30 includes a housing body 31 and a tailgate 33. The housing body 31 has a second opening, and the tailgate 33 is rotatably connected to the housing body 31 to open and close. The wireless receiving component is located inside the tailgate 33 and is opposite to the second opening in the front-rear direction. For example, when the wireless receiving component needs maintenance, the second opening can be opened through the tailgate 33. Opening the tailgate 33 facilitates maintenance of the wireless receiving component, avoiding disassembly of the housing 30 and reducing maintenance costs for the cleaning robot 100.

[0060] In related technologies, cleaning robots, due to size and structural limitations, lack a reasonable layout, resulting in a large vehicle body. When passing sidewalks, auxiliary roads, or park bollards, they may scrape against the vehicle body, causing damage, and even damaging the autonomous driving hardware such as lidar. The cleaning robot 100 of this utility model addresses this by placing the battery 21 at the front, and the electronic control module 22 on top of and in front of the battery 21. A space between the front of the electrical bracket 23 and the housing 30 can accommodate part of the electronic control module 22, saving space in the cleaning robot 100 and facilitating the wiring harness connection between the electronic control module 22 and the battery 21. Furthermore, the water tank 40 is positioned above the walking motor, making efficient use of space and facilitating maintenance of the water tank 40 and drive unit when the side door 32 is open. Sweeping discs are distributed on both sides of the front wheels 12. Compared to placing the sweeping brushes at the front of the front wheels 12, this reduces the overall length of the vehicle and allows for better cleaning performance when used in conjunction with the roller sweeping system.

[0061] In some specific embodiments of this utility model, the chassis may be composed of components such as a driving system, a steering system, a braking system, an electronic control system, a power battery, an electrical support 23, a subframe 14, and a water tank 40 support.

[0062] The housing 30 is mounted on the chassis frame 11 and covers the entire vehicle body, providing protection. The housing 30 consists of a left-side inspection door, a right-side inspection door, a front inspection door, and a tailgate. The left and right inspection doors, when opened, allow access to chassis electrical components, autonomous driving hardware, wiring harnesses, the rear axle drive motor, battery 21, etc.; they also facilitate the replacement of structural components and electrical parts of the sweeping mechanism and cleaning mechanism. The tailgate 33, raised and lowered with the garbage bin 16, provides access to the wireless charging receiver panel, receiver controller, diaphragm pump and water level sensor of the water filling device, the blower of the blower mounting assembly, and the dust removal system's ash-removing motor. The modular design of the housing 30 facilitates disassembly and maintenance of the vehicle's internal structures.

[0063] Optionally, the dustbin 16 can be located behind the rotary sweeper, allowing the garbage swept by the rotary sweeper to fall directly into the dustbin 16. The cleaning robot 100 may also include a dust collection box, which is installed above the dustbin 16 and can directly collect the dust above the dustbin 16.
