Fig. 1 is a schematic view of an overall structure of a cleaning mechanism 10 according to an embodiment of the present application, and fig. 2 is an exploded view of the overall cleaning mechanism 10 according to an embodiment of the present application.

To at least partially solve the above problem, please refer to fig. 1 to 2, embodiments of the present application provide a cleaning mechanism 10, wherein the cleaning mechanism 10 includes a cleaning assembly 100.

Specifically, the sweeping assembly 100 includes a rotating disc 110, an eccentric shaft 120, and an upper cover 130, wherein the rotating disc 110 is coupled to the eccentric shaft 120. The rotating disc 110 is a component of the cleaning assembly 100 that provides power or transmits power, and when the rotating disc 110 actively rotates or is driven by other components to rotate, the cleaning disc in the cleaning assembly 100 can be driven to rotate to clean the ground. For example, in some embodiments, the sweeping assembly 100 further includes a sweeping disk 150 and a central shaft 140, the sweeping disk 150 is disposed outside the receiving cavity 210, one end of the central shaft 140 is connected to the center of the turntable 110, and the other end of the central shaft 140 is connected to the sweeping disk 150, so that the turntable 110 can drive the sweeping disk 150 to rotate, and the floor can be thoroughly swept by using the sweeping disk 150.

The eccentric shaft 120 is disposed on the rotating disc 110, the rotating disc 110 is configured to eccentrically rotate around the eccentric shaft 120, the eccentric shaft 120 and the rotating disc 110 together form an eccentric wheel mechanism, the rotation center of the rotating disc 110 does not coincide with the centroid of the rotating disc 110, i.e., the rotating disc 110 does not rotate around its center, and the rotation range of the eccentric wheel mechanism is larger than that of the rotating disc 110 rotating around its center. Thus, during the rotation of the turntable 110, the area covered by the turntable 110 exceeds the section area of the turntable 110 facing the ground, so as to form a cleaning area with an area larger than the section area of the turntable 110 facing the ground, thereby increasing the cleaning area of the cleaning assembly 100. Moreover, the upper cover 130 and the turntable 110 are arranged at an interval, the upper cover 130 is provided with a guide slot 131, one end of the eccentric shaft 120 departing from the turntable 110 passes through the guide slot 131 and is movably arranged relative to the upper cover 130, so that the guide slot 131 plays a role in limiting and guiding the eccentric shaft 120, and the eccentric shaft 120 can drive the turntable 110 to move along the longitudinal extension direction of the guide slot 131. Therefore, during the operation of the cleaning assembly 100, the rotating disc 110 moves along the longitudinal extension direction of the guiding slot 131 with the eccentric shaft 120 while rotating eccentrically around the eccentric shaft 120, so that the cleaning assembly 100 can cover a wider cleaning area on the cleaning path, i.e. the position of the cleaning assembly 100 is not fixed but can be adjusted, thereby increasing the cleaning area of the cleaning assembly 100 and enhancing the cleaning effect of the cleaning assembly 100.

Fig. 3 is a schematic structural view of a housing 200 of the cleaning mechanism 10 according to an embodiment of the present application from another perspective, and fig. 4 is an enlarged schematic structural view of a connection relationship between the turntable 110 and the eccentric shaft 120 of the cleaning mechanism 10 according to an embodiment of the present application.

Referring to fig. 2 to 4, in order to protect the cleaning assembly 100 and prolong the service life thereof, the cleaning mechanism 10 further includes a housing 200, a receiving cavity 210 is formed in the housing 200, and the turntable 110 is received in the receiving cavity 210. The housing 200 may be used to at least partially house the cleaning assembly 100 therein to isolate the cleaning assembly 100 from the environment, and to provide dust, water, and impact protection to the cleaning assembly 100. Specifically, the housing 200 is provided with a receiving cavity 210, and at least a portion of the cleaning assembly 100 is received in the receiving cavity 210. The housing 200 may be an integrally formed integral structure having a cavity therein, or a split structure having a plurality of cover plates joined together to form the accommodating cavity 210.

The cleaning assembly 100 may be completely received and covered by the receiving cavity 210 in the housing, or only a part of the structure may be received and covered by the receiving cavity 210. In the embodiment of the present application, as shown in fig. 1 and fig. 2, the cleaning assembly 100 is completely received and covered by the receiving cavity 210 in a plane perpendicular to the height direction, and is partially received and covered by the receiving cavity 210 in the height direction, so that the cleaning assembly 100 can be well protected by the housing, and the cleaning operation of the cleaning assembly 100 is not affected. The shape, size, etc. of the housing 200 and the receiving cavity 210 depend on the shape and size of the sweeping assembly 100 and are not particularly limited herein. In order to maintain a relatively stable connection relationship between the housing 200 and the sweeping assembly 100 to some extent during installation and use, and to enable the eccentric shaft 120 to drive the rotating disc 110 to move along the guide slot 131, an end of the eccentric shaft 120 facing away from the rotating disc 110 passes through the guide slot 131 and is connected to the housing 200, so that the eccentric shaft 120 can drive the rotating disc 110 and the housing 200 to move relatively. The eccentric shaft 120 and the housing 200 may be directly connected or indirectly connected through a connecting member.

In some embodiments, a fixing seat 220 is disposed on a side of the housing 200 facing the rotating disc 110, a first shaft sleeve 230 is disposed in the fixing seat 220, and an end of the eccentric shaft 120 facing away from the rotating disc 110 is inserted into the first shaft sleeve 230, so that the eccentric shaft 120 is connected to the fixing seat 220 on the housing 200 through the shaft sleeve, which not only ensures that the eccentric shaft 120 cannot be separated from the housing 200, but also enables the eccentric shaft 120 to rotate in the fixing seat 220, i.e., the eccentric shaft 120 is rotatably connected to the fixing seat 220. During the operation of the cleaning assembly 100, when the rotating disc 110 eccentrically rotates around the eccentric shaft 120, the eccentric shaft 120 also rotates relative to the fixed base 220, the outer housing 200 and the upper cover 130 remain stationary, and when the rotating disc 110 moves along the longitudinal extension direction of the guide slot 131 along with the eccentric shaft 120, the eccentric shaft 120 drives the fixed base 220 and the outer housing 200 to move together, and the upper cover 130 remains stationary.

As described above, when the rotating disc 110 moves along the longitudinal extension direction of the guiding slot 131 along with the eccentric shaft 120, the eccentric shaft 120 drives the fixed seat 220 and the housing 200 to move together, and the upper cover 130 remains stationary, i.e. the housing 200 and the upper cover 130 move relatively, in order to maintain the structural stability of the housing 200 and the upper cover 130 during the relative movement between the housing 200 and the upper cover 130, in some embodiments, as shown in fig. 2 and 3, the side of the upper cover 130 facing the housing 200 is provided with the first sliding slot 132, the longitudinal extension direction of the first sliding slot 132 is parallel to the longitudinal extension direction of the guiding slot 131, the housing 200 is provided with the sliding strip 240 matching with the first sliding slot 132, so that during the operation of the cleaning mechanism 10, the sliding strip 240 is embedded in the first sliding slot 132 to maintain the stable connection between the housing 200 and the upper cover 130, and at the same time, the sliding strip 240 can slide in the first sliding slot 132, so that the housing 200 is slidably coupled to the upper cover 130 without affecting the relative movement between the housing 200 and the upper cover 130.

In order to make the connection between the eccentric shaft 120 and the rotating disc 110 more compact and make the rotation of the rotating disc 110 smoother, as shown in fig. 2 and 4, in some embodiments, a second sliding slot 111 surrounding the center of the rotating disc 110 is provided on the rotating disc 110, one end of the eccentric shaft 120 is provided in the second sliding slot 111, and the eccentric shaft 120 is configured to be able to slide along the second sliding slot 111 to drive the rotating disc 110 to move along the longitudinal extension direction of the guiding slot 131. At different positions in the second sliding groove 111, the distance from the center of the rotating disc 110 changes, and the eccentric shaft 120 is disposed in the second sliding groove 111. Thus, when the eccentric shaft 120 rotates along the second sliding slot 111 in the second sliding slot 111, the distance from the eccentric shaft 120 to the center of the rotating disc 110 changes, so that the rotating disc 110 can eccentrically rotate, and the rotating characteristic of the eccentric wheel is satisfied. The structure of the second sliding groove 111 may be a regular symmetrical pattern or an irregular pattern, and may be flexibly adjusted according to the rotation characteristic of the turntable 110, which is not limited herein.

On the basis of the above embodiments, further, in order to enable the eccentric shaft 120 to conveniently rotate and slide along the second sliding chute 111 at the same time, in some embodiments, one end of the eccentric shaft 120, which is disposed in the second sliding chute 111, is sleeved with a second shaft sleeve 121, and an outer wall of the second shaft sleeve 121 abuts against an inner wall of the second sliding chute 111. So, because the outer wall of second shaft sleeve 121 has promoted the fastening degree of second shaft sleeve 121 in second spout 111 with the inner wall butt of second spout 111, eccentric shaft 120 can enough produce the rotation relative to second shaft sleeve 121, again can slide in second spout 111 along with second shaft sleeve 121 together, and each other does not influence between the two, can go on simultaneously, makes eccentric shaft 120's removal more smooth and easy.

Further, on the basis of the above embodiment, the second sliding chute 111 comprises two guiding sections 1111 disposed opposite to each other with respect to the center of the rotating disc 110 and two splicing sections 1112 disposed opposite to each other with respect to the center of the rotating disc 110, wherein the longitudinal extension direction of the guiding sections 1111 is parallel to the longitudinal extension direction of the guiding grooves 131, and the longitudinal extension direction of the splicing sections 1112 is perpendicular to the longitudinal extension direction of the guiding grooves 131. That is, the longitudinal extension direction of the guide section 1111 of the second sliding groove 111 is parallel to the longitudinal extension direction of the guide groove 131, and when the eccentric shaft 120 slides along the guide section 1111, the eccentric shaft 120 can also slide along the second sliding groove 111 at the same time, thereby serving to adjust the eccentricity of the cleaning assembly 100. And the longitudinal extension direction of the splicing section 1112 in the second sliding slot 111 is perpendicular to the longitudinal extension direction of the guide slot 131, and when the eccentric shaft 120 slides along the guide section 1111, the eccentric shaft 120 cannot slide along the guide slot 131. It should be noted that the second sliding chute 111 may be formed by only connecting the two guiding sections 1111 disposed opposite to the center of the rotating disk 110 and the two splicing sections 1112 disposed opposite to the center of the rotating disk 110 at first positions, or may further include other sections with different functions, such as transition sections, etc., the specific structure of the second sliding chute 111 may be adjusted according to actual use requirements, and each of the guiding sections 1111, the splicing sections 1112, the transition sections, etc., are divided according to the function of the second sliding chute 111 when in use, and their positions in the second sliding chute 111 are different, while their structures may be the same or different, and there may or may not be a distinct boundary between them.

As mentioned above, the rotating disc 110 is a component of the cleaning assembly 100 that performs a power supplying or power transmitting function, and when the rotating disc 110 actively rotates or is driven by other components to rotate, the cleaning disc in the cleaning assembly 100 can be driven to rotate to clean the ground. In order to improve the cleaning efficiency of the cleaning mechanism 10, please refer to fig. 5 in combination with fig. 2, the cleaning mechanism 10 further includes a driving device 300, the driving device 300 has an output shaft 310 and a transmission shaft 320, one end of the output shaft 310 is provided with an offset slot 311, a longitudinal extending direction of the offset slot 311 is parallel to a longitudinal extending direction of the guide slot 131, one end of the transmission shaft 320 is disposed in the offset slot 311 and is in transmission connection with the output shaft 310, and the other end of the transmission shaft 320 is in transmission connection with the rotating disc 110, so that the transmission shaft 320 can move along the longitudinal extending direction of the offset slot 311 along with the rotating disc 110. That is, the output shaft 310 of the driving device 300 is in transmission connection with the rotating disc 110 through the transmission shaft 320, and the power transmission is performed through the rotating disc 110 to drive the cleaning disc 150 to rotate, so as to clean the ground, thereby improving the working efficiency of the cleaning mechanism 10. The driving device 300 may employ various types of motors, which are not limited herein. One end of the output shaft 310 is provided with an offset slot 311, the longitudinal extension direction of the offset slot 311 is parallel to the longitudinal extension direction of the guide slot 131, when the rotary table 110 moves along the longitudinal extension direction of the guide slot 131 along with the eccentric shaft 120, the eccentric shaft 120 drives the fixed base 220 and the housing 200 to move together, at this time, the transmission shaft 320 is also driven by the rotary table 110 to move along the longitudinal extension direction of the guide slot 131, and the end of the transmission shaft 320 connected with the output shaft 310 can move in the offset slot 311 without abutting against the output shaft 310 to affect the normal operation of the output shaft 310.

In the process of applying the cleaning mechanism 10 to the cleaning robot 20, it is often necessary to arrange a plurality of cleaning assemblies 100 in the cleaning assembly 100 for cleaning simultaneously to improve the cleaning efficiency, and therefore, in some embodiments, the cleaning mechanism 10 includes at least two cleaning assemblies 100 arranged at intervals, and the two cleaning assemblies 100 are arranged at intervals relatively to each other to perform cleaning operation simultaneously, so that the cleaning area of the cleaning mechanism 10 at the same time is increased by times, and the cleaning efficiency of the cleaning mechanism 10 is also greatly improved.

Referring to fig. 6 together with fig. 1 and fig. 2, in some embodiments, a connecting line of the two eccentric shafts 120 may be parallel to a longitudinal extending direction of the guide slot 131. Since each cleaning assembly 100 can adjust its eccentricity along the lengthwise extension direction of the guide slot 131, when the connecting direction of the two eccentric shafts 120 is parallel to the lengthwise extension direction of the guide slot 131, any one cleaning assembly 100 can move toward or away from the other cleaning assembly 100.
