Description

Technical Field

[0001] This utility model relates to the field of intelligent robot technology, and in particular to a cleaning structure and a cleaning robot. Background Technology

[0002] With the development of automation technology and artificial intelligence, the demand for intelligent robots is becoming increasingly widespread; the arrival of the robot era will transform existing production and manufacturing models and human lifestyles. Cleaning robots, as an application of intelligent technology, are suitable for various outdoor and large indoor environments, such as plazas, parks, communities, underground parking garages, and other enclosed areas.

[0003] Currently, cleaning robots all employ a fixed cleaning structure, which significantly limits their ability to navigate the environment and roads during cleaning operations. Existing technologies also include cleaning structures that can automatically raise and lower, such as those where the output end of a cylinder is connected to the cleaning head, allowing the head to move up and down via the cylinder's extension and retraction. However, these designs suffer from the problem of occupying a large amount of vertical space. Therefore, there is an urgent need for a cleaning structure and a cleaning robot that can solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a cleaning structure and a cleaning robot. The cleaning structure can automatically lift and lower to cope with the impact of various terrain environments, and it occupies less vertical space and has a more compact structure.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] On the one hand, a cleaning structure is provided, including:

[0007] Mounting base;

[0008] The driving component is fixed to the mounting base;

[0009] The transmission assembly includes a first transmission component and a second transmission component. The first transmission component is fixed to the output end of the driving component. The driving component is used to drive the first transmission component to rotate. The outer wall side of the first transmission component is threadedly connected to the inner wall side of the second transmission component.

[0010] A cleaning assembly is sleeved on the outer wall of the second transmission member. The second transmission member can drive the cleaning assembly to rotate. The cleaning assembly includes a first cleaning member and a second cleaning member. The second cleaning member is connected to the first cleaning member, and at least one end of the first cleaning member is detachably connected to the second cleaning member.

[0011] In some possible implementations, the outer wall of the first transmission member is provided with a threaded protrusion, and the inner wall of the second transmission member is provided with a threaded groove, wherein the threaded protrusion and the threaded groove are threadedly connected.

[0012] In some possible implementations, the first end of the first cleaning member is hinged to the first end of the second cleaning member, and the second end of the first cleaning member is detachably connected to the second end of the second cleaning member.

[0013] In some possible implementations, one of the second ends of the first cleaning member and the second cleaning member is provided with a male hook and the other with a female hook and the male hook and the female hook cooperate.

[0014] In some possible implementations, the outer wall of the second transmission member is provided with two annular protrusions spaced apart, the annular protrusions extending circumferentially along the second transmission member, and the first cleaning member and the second cleaning member are both sandwiched between the two annular protrusions.

[0015] In some possible implementations, the outer wall of the second transmission member is provided with a first positioning protrusion, and the inner walls of the first cleaning member and the second cleaning member are both provided with second positioning protrusions. The first positioning protrusion abuts against the second positioning protrusion so that the second transmission member drives both the first cleaning member and the second cleaning member to rotate.

[0016] In some possible implementations, the mounting base is configured to pass through the frame.

[0017] In some possible implementations, the first transmission element is sleeved outside the drive element.

[0018] In some possible implementations, the drive element is a coreless motor.

[0019] On the other hand, a cleaning robot is provided, including a frame and a cleaning structure as described in any of the above embodiments, the cleaning structure being disposed on the frame.

[0020] The beneficial effects of this utility model are:

[0021] The cleaning structure provided by this utility model includes a mounting base, a driving component, a transmission assembly, and a cleaning assembly. During operation, because the outer wall of the first transmission component is threadedly connected to the inner wall of the second transmission component, when the driving component rotates forward, it drives the first transmission component to rotate and causes the second transmission component to move downward, thus completing the descent of the cleaning assembly. When the driving component rotates in reverse, it causes the second transmission component to move upward, thus completing the lifting of the cleaning assembly. Therefore, the cleaning structure can automatically lift and lower to cope with the influence of various terrain environments. Furthermore, the threaded connection between the outer wall of the first transmission component and the inner wall of the second transmission component enables the lifting and lowering of the cleaning assembly, improving the accuracy of movement. Since the cleaning assembly is sleeved on the outer wall of the second transmission component, and the outer wall of the first transmission component is threadedly connected to the inner wall of the second transmission component, the first transmission component, the second transmission component, and the cleaning assembly overlap in the vertical portion, thereby reducing the vertical space occupied by the first transmission component, the second transmission component, and the cleaning assembly, resulting in a smaller vertical space occupied by the cleaning structure and a more compact structure. Furthermore, at least one end of the first cleaning component is detachably connected to the second cleaning component, which facilitates the assembly of the cleaning component and the second transmission component, and makes it easier to replace the cleaning component.

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.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

[0034] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 7As shown, this utility model provides a cleaning structure, including a mounting base 1, a driving component 2, a transmission assembly, and a cleaning assembly 5. The driving component 2 is fixed to the mounting base 1. The transmission assembly includes a first transmission component 3 and a second transmission component 4. The first transmission component 3 is fixed to the output end of the driving component 2, and the driving component 2 is used to drive the first transmission component 3 to rotate. The outer wall of the first transmission component 3 is threadedly connected to the inner wall of the second transmission component 4. The cleaning assembly 5 is sleeved on the outer wall of the second transmission component 4, and the second transmission component 4 can drive the cleaning assembly 5 to rotate. The cleaning assembly 5 includes a first cleaning component 51 and a second cleaning component 52. The second cleaning component 52 is connected to the first cleaning component 51. At least one end of the first cleaning component 51 is detachably connected to the second cleaning component 52, that is, one end of the first cleaning component 51 is detachably connected to the second cleaning component 52, or both ends of the first cleaning component 51 are detachably connected to the second cleaning component 52.

[0037] During operation, because the outer wall of the first transmission component 3 is threadedly connected to the inner wall of the second transmission component 4, when the drive component 2 rotates forward, it drives the first transmission component 3 to rotate and causes the second transmission component 4 to move downward, thus completing the descent of the sweeping assembly 5. When the drive component 2 rotates in reverse, it causes the second transmission component 4 to move upward, thus completing the lifting of the sweeping assembly 5. Therefore, the sweeping structure can automatically lift and lower to cope with the effects of various terrain environments. In addition, the lifting and lowering movement of the sweeping assembly 5 is achieved through the threaded connection between the outer wall of the first transmission component 3 and the inner wall of the second transmission component 4, which improves the accuracy of movement. Since the sweeping assembly 5 is sleeved on the outer wall of the second transmission component 4, and the outer wall of the first transmission component 3 is threadedly connected to the inner wall of the second transmission component 4, the first transmission component 3, the second transmission component 4, and the sweeping assembly 5 overlap vertically, thereby reducing the vertical space occupied by the first transmission component 3, the second transmission component 4, and the sweeping assembly 5, making the sweeping structure occupy less vertical space and more compact. Furthermore, at least one end of the first cleaning component 51 is detachably connected to the second cleaning component 52, which facilitates the assembly of the cleaning component 5 and the second transmission component 4, and makes it easier to replace the cleaning component 5.

[0038] Optionally, in this embodiment, the mounting base 1 is configured to pass through the frame 100. This arrangement allows the frame 100 and the mounting base 1 to overlap vertically, saving vertical space occupied by the mounting base 1 and the frame 100, resulting in a more compact structure. To facilitate the assembly and disassembly of the mounting base 1 and ensure a more secure connection between the mounting base 1 and the frame 100, the mounting base 1 includes a first base 11 and a second base 12. The first base 11 overlaps and is detachably connected to the frame 100, and its bottom passes through the frame 100 and is detachably connected to the second base 12. The driving component 2 is disposed on the second base 12.

[0039] Optionally, in this embodiment, the outer wall of the first transmission member 3 is provided with a threaded protrusion 31, and the inner wall of the second transmission member 4 is provided with a threaded groove 41, with the threaded protrusion 31 and the threaded groove 41 threadedly connected. By providing the threaded protrusion 31 on the outer wall of the first transmission member 3 and the threaded groove 41 on the inner wall of the second transmission member 4, the second transmission member 4 can be raised and lowered by the movement of the threaded groove 41 relative to the threaded protrusion 31. Specifically, multiple threaded protrusions 31 are spaced apart and encircle the outer wall of the first transmission member 3 once, while a threaded groove 41 encircles the inner wall of the second transmission member 4 multiple times. This arrangement reduces the contact area between the threaded protrusion 31 and the threaded groove 41, making the raising and lowering movement smoother. Furthermore, the multiple threaded protrusions 31 are located at the middle position along the height direction of the outer wall of the first transmission member 3. Positioning the multiple threaded protrusions 31 at the middle position along the height direction of the outer wall of the first transmission member 3 allows part of the first transmission member 3 to extend into the second transmission member 4, and part of the first transmission member 3 to contact the inner wall of the second transmission member 4, improving the stability of the movement of the second transmission member 4.

[0040] Optionally, such as Figure 4 and Figure 5 As shown, the first transmission component 3 is sleeved outside the driving component 2. Sleeving the first transmission component 3 outside the driving component 2 protects the driving component 2 and reduces the possibility of dust falling onto it. Specifically, the first transmission component 3 includes an annular portion 32 and a connecting portion 33. The annular portion 32 is sleeved outside the driving component 2, and the connecting portion 33 is located at the middle position along the height direction inside the annular portion 32. The connecting portion 33 is used to connect to the output end of the driving component 2.

[0041] Optionally, such as Figure 2 , Figure 6 and Figure 7 As shown, in this embodiment, the first end of the first cleaning member 51 is hinged to the first end of the second cleaning member 52, and the second end of the first cleaning member 51 is detachably connected to the second end of the second cleaning member 52. When installing the cleaning assembly 5 on the outer wall of the second transmission member 4, it is only necessary to connect the second end of the first cleaning member 51 to the second end of the second cleaning member 52, which can save installation time and improve installation efficiency.

[0042] Optionally, one of the second ends of the first cleaning member 51 and the second end of the second cleaning member 52 is provided with a male hook-and-loop fastener 53, and the other is provided with a female hook-and-loop fastener 54, which cooperate with each other. The cooperation of the male hook-and-loop fastener 53 and the female hook-and-loop fastener 54 achieves a detachable connection between the second ends of the first cleaning member 51 and the second cleaning member 52, resulting in a relatively simple structure and convenient connection. The male hook-and-loop fastener 53 and the female hook-and-loop fastener 54 are mature technologies in related fields, and will not be described in detail in this embodiment. In other embodiments, both ends of the first cleaning member 51 are detachably connected to the second cleaning member 52. Optionally, two male hook-and-loop fasteners 53 and two female hook-and-loop fasteners 54 are provided. One male hook-and-loop fastener 53 and one female hook-and-loop fastener 54 are used to connect the first end of the first cleaning member 51 to the first end of the second cleaning member 52, and the other male hook-and-loop fastener 53 and the other female hook-and-loop fastener 54 are used to connect the second end of the first cleaning member 51 to the second end of the second cleaning member 52.

[0043] To define the positions of the first cleaning component 51 and the second cleaning component 52 in the height direction of the second transmission component 4, optionally, two annular protrusions 42 are provided at intervals on the outer wall of the second transmission component 4. The annular protrusions 42 extend circumferentially along the second transmission component 4, and the first cleaning component 51 and the second cleaning component 52 are both sandwiched between the two annular protrusions 42. By setting the annular protrusions 42 to define the positions of the first cleaning component 51 and the second cleaning component 52, the limiting effect is good. Optionally, both the first cleaning component 51 and the second cleaning component 52 include a semi-annular rod 20 and a side brush 30. The semi-annular rod 20 is sandwiched between the two annular protrusions 42, and the side brush 30 is fixed to the semi-annular rod 20. This arrangement facilitates the installation of the first cleaning component 51 and the second cleaning component 52, and allows cleaning to be performed by the side brush 30.

[0044] Optionally, the outer wall of the second transmission member 4 is provided with a first positioning protrusion 43, and the inner walls of the first cleaning member 51 and the second cleaning member 52 are both provided with second positioning protrusions 10. The first positioning protrusion 43 abuts against the second positioning protrusions 10, so that the second transmission member 4 drives both the first cleaning member 51 and the second cleaning member 52 to rotate. With this configuration, the second transmission member 4 can easily drive the first cleaning member 51 and the second cleaning member 52, without requiring the inner walls of the first cleaning member 51 and the second cleaning member 52 to be completely pressed against the second transmission member 4 to achieve the driving of the first cleaning member 51 and the second cleaning member 52 by the second transmission member 4. Optionally, the first positioning protrusion 43 has an H-shaped structure, and the two ends of the H-shaped structure extend to two annular protrusions 42 respectively. This configuration can improve the structural strength of the second transmission member 4.

[0045] Optionally, the drive component 2 is a coreless motor. Coreless motors have high energy conversion efficiency, small size, and light weight, which can reduce the overall weight of the cleaning structure.

[0046] This utility model also provides a cleaning robot, including a frame 100 and the aforementioned cleaning structure, the cleaning structure being disposed on the frame 100. The cleaning structure of this cleaning robot can automatically raise and lower to cope with the impact of various terrain environments, and occupies less vertical space, resulting in a compact structure. Optionally, two cleaning structures are provided, both of which are detachably connected to the frame 100. Providing two cleaning structures can improve cleaning efficiency.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
