Detailed Implementation

[0027] 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.

[0028] Combination Figure 1 and Figure 2 According to an embodiment of the present invention, a sanitation robot 100 includes a frame 10, a garbage dumping assembly 20, a power assembly 30, and a cover 40. The cover 40 covers the outside of the frame 10, the garbage dumping assembly 20, and the power assembly 30. Exemplarily, the power assembly 30 may include components such as a power battery, a drive motor, and a drive shaft. The power assembly 30 provides power to the sanitation robot 100 and drives its movement and operations. The garbage dumping assembly 20 is used to collect and dump garbage. The cover 40, covering the outside of the frame 10, the garbage dumping assembly 20, and the power assembly 30, protects the vehicle components, provides a stable working environment, and prevents rainwater, dust, etc., from entering the power assembly 30 and the garbage dumping assembly 20 and affecting them.

[0029] The casing 40 includes a main body 41 and multiple inspection doors. These inspection doors are located on the front, rear, left, and right sides of the main body 41. The inspection doors are configured to open and close the internal space of the casing 40. By providing multiple inspection doors, it is convenient to inspect and maintain the sanitation robot 100, avoiding the need to disassemble the casing 40 and increase the maintenance costs of the sanitation robot 100. For example, when the sanitation robot 100 malfunctions or requires maintenance, the internal space of the casing 40 can be quickly opened by opening the inspection doors to facilitate the maintenance or replacement of the sanitation robot 100's components.

[0030] According to the embodiment of the present utility model, the sanitation robot 100 is provided with a cover 40 covering the outside of the frame 10, the power component 30 and the garbage dumping component 20, which can protect the components inside the vehicle and provide a stable working environment. In addition, the cover 40 is provided with multiple inspection doors, which facilitates inspection and maintenance from the front, rear, left and right sides of the sanitation robot 100, thereby reducing the maintenance cost of the sanitation robot 100.

[0031] Combination Figure 3 and Figure 4 In some embodiments of this utility model, multiple maintenance doors include a tailgate 421, which is located on the rear side of the shell body 41. The upper end of the tailgate 421 is rotatably connected to the shell body 41, and the tailgate 421 is linked with the garbage dumping assembly 20. Specifically, the sanitation robot 100 can achieve automatic driving and automatic garbage dumping. The tailgate 421 is linked with the garbage dumping assembly 20 to facilitate garbage dumping by the sanitation robot 100. For example, the tailgate 421 can be opened by a drive device, which simultaneously lifts the garbage dumping assembly 20, or the garbage dumping assembly 20 can be lifted by a drive device, which simultaneously opens the tailgate 421 to facilitate garbage dumping by the sanitation robot 100. In addition, after opening the tailgate 421, the components inside the tailgate 421 can be inspected, improving the maintenance convenience of the sanitation robot 100.

[0032] For example, the sanitation robot 100 can dock with a workstation for wireless charging. The workstation may be equipped with a wireless charging component, and the sanitation robot 100 may be equipped with a wireless receiving component connected to a power battery, so that the sanitation robot 100 can be wirelessly charged through the workstation. The wireless receiving component may be located inside the tailgate 421, which facilitates docking and charging of the sanitation robot 100 with the workstation, and also allows for inspection and maintenance of the wireless receiving component by opening the tailgate 421.

[0033] The tailgate 421 can be designed as an integral structure. When the tailgate 421 is closed, it can protect both the garbage dumping component 20 and the wireless receiving component, simplifying the structure of the sanitation robot 100. Compared with the structure of using an independent cover to protect the battery in related technologies, it can improve the waterproof performance of the sanitation robot 100.

[0034] Combination Figures 3 to 5In some embodiments of this utility model, the garbage dumping assembly 20 includes a garbage hopper 21 and a lifting mechanism 22. The garbage hopper 21 has a retracted position and a lifted position. The lifting mechanism 22 drives the garbage hopper 21 to move between the retracted position and the lifted position. In the retracted position, the tailgate 421 is closed and covers the outside of the garbage hopper 21 and the lifting mechanism 22. Specifically, the garbage hopper 21 can be used to collect and store garbage swept by the sanitation robot 100 during operation. The lifting mechanism 22 can drive the garbage hopper 21 to move, wherein, combined with Figure 3 In its retracted position, the garbage bin 21 can be used to collect and store garbage, and the tailgate 421, in conjunction with the shell body 41, can protect the garbage bin 21 and the lifting mechanism 22. Figure 4 When the garbage bin 21 is in the lifted position, it can be emptied by extending the cover 40 via the lifting mechanism 22. In the retracted position, the tailgate 421 closes and covers the garbage bin 21 and the lifting mechanism 22, preventing rainwater from entering the garbage bin 21 and causing bacterial growth, and also preventing rainwater from entering the lifting mechanism 22 and affecting its performance.

[0035] Combination Figure 4 Furthermore, the garbage dumping assembly 20 also includes a connecting rod 50, which is rotatably connected to the garbage bin 21 and the tailgate 421 respectively. When the garbage bin 21 is in the lifted position, the connecting rod 50 can support the rotation of the garbage bin 21 to dump the garbage inside the garbage bin 21.

[0036] Combination Figures 3 to 5 In some embodiments of this utility model, the lifting mechanism 22 includes: a fixed base 221, a rotating arm 222, and an unloading assembly 223. The fixed base 221 is connected to the vehicle frame 10; one end of the rotating arm 222 is rotatably connected to the fixed base 221, and the other end is rotatably connected to the garbage hopper 21; the unloading assembly 223 is rotatably connected to the fixed base 221 and the garbage hopper 21; wherein, the fixed base 221, the rotating arm 222, the garbage hopper 21, and the unloading assembly 223 form a first four-bar linkage 50 mechanism. Specifically, the rotating arm 222 can drive the garbage hopper 21 to move between the retracted position and the lifting position. When the garbage hopper 21 moves from the retracted position to the lifting position, the first four-bar linkage 50 mechanism can ensure that the garbage hopper 21 translates, that is, during the rotation of the rotating arm 222, the garbage hopper 21 translates without rotating, thus preventing the garbage in the garbage hopper 21 from falling out during the lifting process.

[0037] The lifting mechanism 22 also includes a discharge assembly 223. After the garbage bin 21 is driven to the lifting position by the rotating arm 222, the garbage bin 21 can be rotated by the discharge assembly 223 to dump the garbage in the garbage bin 21.

[0038] For example, the rotating arm 222 can be driven to rotate by the first electric push rod. When the garbage bin 21 is in the retracted position, the first electric push rod can drive the rotating arm 222 to rotate backward and upward to drive the garbage bin 21 to move to the lifting position. When the garbage bin 21 is in the lifting position, the first electric push rod can drive the rotating arm 222 to rotate downward and forward to drive the garbage bin 21 to move to the retracted position.

[0039] Optionally, the unloading assembly 223 may include an unloading arm and a second electric push rod, the second electric push rod being connected to the unloading arm and rotatably connected to the fixed base 221 and the garbage bin 21 respectively.

[0040] In addition, the connecting rod 50, the rotating arm 222, the shell body 41 and the tailgate 421 form a second four-bar linkage 50 mechanism. Specifically, when the rotating arm 222 moves the garbage bin 21 to the lifting position, the tailgate 421 can be opened simultaneously under the action of the second four-bar linkage 50 mechanism. The connecting rod 50 is rotatably connected to the garbage bin 21 and the tailgate 421 is rotatably connected. When the garbage bin 21 is in the lifting position, it can stably unload the garbage bin 21 through the unloading assembly 223, thereby improving the movement stability of the garbage bin 21.

[0041] Combination Figure 6 In some embodiments of this utility model, the sanitation robot 100 includes an unmanned driving control module 60, which is mounted on the frame 10.

Multiple maintenance doors, including a front door 424, are connected to the front side of the main body 41, and the unmanned driving control module 60 is located inside the front door 424. Exemplarily, the unmanned driving control module 60 can realize path planning for the sanitation robot 100, and control the robot's acceleration, steering, braking, and other actions according to the planned path. The unmanned driving control module 60 can also process environmental information acquired by cameras, radar, etc. The cover 40 protects the unmanned driving control module 60. Furthermore, the front door 424 facilitates the inspection and maintenance of the unmanned driving control module 60, improving the maintenance convenience of the sanitation robot 100. For example, when the unmanned module needs to be inspected and maintained, the front door 424 can be opened to avoid disassembling the cover 40 and reduce the maintenance cost of the sanitation robot 100.

[0042] The upper end of the front door 424 is rotatably connected to the shell body 41 so as to open the front door 424 and inspect the unmanned driving control module 60.

[0043] Combination Figure 2 and Figure 6In some embodiments of this utility model, the multiple inspection doors include a left door 422 and a right door 423. The left door 422 is connected to the left side of the shell body 41, and the right door 423 is connected to the right side of the shell body 41. The internal space of the cover 40 can be opened through the left door 422 and the right door 423.

[0044] The power assembly 30 is mounted on the frame 10 and is distributed laterally to the left and right doors 422 and 423, respectively. This means that the power assembly 30 can be accessed for maintenance by opening either the left or right door. For example, the power assembly 30 may include components such as a power battery, a motor, a drive shaft, and a reducer. The power assembly 30 drives the movement and operation of the sanitation robot 100. The power battery, as a power source, supplies power to the sanitation robot 100, while the motor, drive shaft, and reducer drive the robot's movement. A cover 40 is installed on the outside of the power assembly 30, protecting it from rainwater and dust that could enter the motor, drive shaft, and other components, thus affecting its lifespan. Furthermore, the left and right doors 422 and 423 facilitate maintenance and repair of the power assembly 30 from both sides of the casing, improving the ease of maintenance for the sanitation robot 100. For example, when it is necessary to replace the power battery, the left door 422 or the right door 423 can be opened to avoid disassembling the cover 40, thereby reducing the maintenance cost of the sanitation robot 100.

[0045] Combination Figure 6 and Figure 7 In some embodiments of this utility model, the sanitation robot 100 further includes a roller brush assembly 70, with a cover 40 covering the outside of the roller brush assembly 70. The roller brush assembly 70 is arranged in a left-right direction and located inside the left side door 422 and the right side door 423. For example, the roller brush assembly 70 can collect garbage from the ground into the garbage bin 21 by rotating. The cover 40, covering the outside of the roller brush assembly 70, protects it from rainwater and other contaminants entering the inside and prevents it from colliding with obstacles. Furthermore, the left side door 422 and the right side door 423 facilitate inspection and maintenance of the roller brush assembly 70, improving the maintenance convenience of the sanitation robot 100. For example, when inspection and maintenance of the roller brush assembly 70 is required, the left side door 422 or the right side door 423 can be opened, avoiding the need to disassemble the cover 40 and reducing the maintenance cost of the sanitation robot 100.

[0046] Combination Figure 8 and Figure 9, in some embodiments of the present utility model, the at least one access door comprises: a door main body 431 and a door hinge 432; the door hinge 432 comprises a connecting portion 4321 and an arc-shaped portion 4322, the connecting portion 4321 is hinged to the housing main body 41, one end of the arc-shaped portion 4322 is connected to the connecting portion 4321 and extends around the rotation center axis of the connecting portion 4321, the other end of the arc-shaped portion 4322 is connected to the door main body 431, and the arc-shaped portion 4322 extends out of the inner space of the housing 40 when the access door is opened. The connecting portion 4321 and the arc-shaped portion 4322 may be connected in a "Ω"-shape, which allows the door main body 431 to bypass the door frame of the housing main body 41 when the access door is opened, so that there is no interference during the opening process of the access door. In addition, by providing the aforementioned door hinge 432, it is convenient to maximize the access area when the access door is opened. For example, the left door 422 and the right door 423 may comprise the door main body 431 and the door hinge 432, and in combination with the foregoing, the power assembly 30, the roller brush assembly 70 and the like may be accessed by opening the left door 422 and the right door 423.

[0047] wherein, the door hinge 432 and the housing main body 41 may be connected by a hinge. For example, the housing 40 may further comprise a mounting seat, the connecting portion 4321 and the hinge may be connected by bolts, the hinge is connected to the mounting seat by bolts, the mounting seat is fixed to the housing main body 41 by bolts, the door hinge 432 can rotate via the hinge to complete the opening and closing movement of the door main body 431. By providing the arc-shaped portion 4322, the door main body 431 can bypass the door frame of the housing main body 41, so that there is no interference during the opening process of the door main body 431.

[0048] optionally, the housing main body 41 or the access door may be provided with a waterproof rubber strip, which can seal the gap between the access door and the housing main body 41 and improve the waterproof performance of the housing 40.

[0049] in combination with Figure 6 , wherein, the left door 422 may comprise the door main body 431 and the door hinge 432, the right door 423 may comprise the door main body 431 and the door hinge 432, two door hinges 432 may be arranged along the up-down direction, which improves the stability of the left door 422 and the right door 423 during opening and closing.

[0050] Optionally, the left door 422 and / or the right door 423 have a hinged end and a free end, with the hinged end closer to the tailgate 421 than the free end. This means the left door 422 and / or the right door 423 can be opened from front to back. For example, the sanitation robot 100 can be streamlined in the front-to-back direction, reducing resistance during its movement. Specifically, the front of the sanitation robot 100 is lower than its rear, and the hinged ends of the left door 422 and / or the right door 423 are closer to the rear. This improves the connection stability between the left door 422 and / or the right door 423 and the main body 41, and facilitates the inspection of the internal structure of the sanitation robot 100 when the left door 422 and / or the right door 423 are open.

[0051] Combination Figure 3 In some embodiments of this utility model, the sanitation robot 100 has a first water guide channel 411 on its shell body 41. The first water guide channel 411 is located at the rear of the top wall of the shell body 41 and extends in the left-right direction. Specifically, the first water guide channel 411 can guide rainwater on the top of the sanitation robot 100, preventing rainwater from accumulating on the upper side of the shell body 41.

[0052] In addition, the first water guide channel 411 is located at the rear of the top wall of the shell body 41, which can prevent rainwater from entering the garbage dumping assembly 20 through the gap between the tailgate 421 and the shell body 41, thereby preventing garbage and rainwater from mixing and breeding bacteria, and improving the waterproof performance of the cover 40.

[0053] Furthermore, the shell body 41 is also provided with a second water guide channel and a third water guide channel. The second water guide channel extends in the vertical direction and connects to one end of the first water guide channel 411. The third water guide channel extends in the vertical direction and connects to the other end of the first water guide channel 411. The second water guide channel and the third water guide channel work together to guide the water in the first water guide channel 411, preventing the water in the first water guide channel 411 from spreading to the gap between the shell body 41 and the inspection door, thereby improving the waterproof performance of the cover 40.

[0054] In some embodiments of this utility model, at least a portion of the top surface of the shell body 41 is inclined downward from the middle to the left and right sides, which can guide the water on the top surface of the shell body 41 to flow from the middle to the sides, and prevent rainwater from accumulating on the top surface of the shell body 41 on rainy days.

[0055] In conjunction with the foregoing, the top of the sanitation robot 100 is provided with a first water guide channel 411 extending in the left and right direction. Through the design of the aforementioned shell body 41, it is easy to guide the water in the first water guide channel 411 to flow to the left and right sides, so as to avoid water accumulation on the top of the shell body 41.

[0056] In some embodiments of this utility model, the cover 40 is made of ABS plastic, which can reduce the weight of the sanitation robot 100 and thus reduce its energy consumption. For example, the cover 40 can be made of ABS plastic, which can balance lightweight (30% weight reduction compared to metal shells) and impact resistance.

[0057] Furthermore, the outer surface of the cover 40 is coated with a UV coating to prevent the cover 40 from aging and to extend the service life of the sanitation robot 100.

[0058] In some embodiments of this utility model, the sanitation robot further includes front wheels and rear wheels, with a cover covering the outside of the front and rear wheels.
