Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a transmission component and a cleaning equipment. Background Art

[0002] Sweeping robots have become popular in the homes of many users. When sweeping carpets and wooden floors, the mop sticking to the ground will cause damage to the ground or too much resistance, making it impossible to move forward. When crossing obstacles, the mop sticking to the ground will also increase the difficulty of crossing obstacles. In the related art, it is usually necessary to add a set of mechanisms with a separate power actuator to the sweeping robot to drive the mop to the wall, and then raise or lower the mop by the forward and reverse rotation of the motor to achieve edge cleaning of the sweeping robot. However, when adjusting the rise or fall of the mop, the driving mechanism is driven by a motor to achieve the lifting of the mop. However, the existing drive mechanism has low coordination accuracy, which affects the accuracy of the mop rising. Utility Model Content

[0093] Please refer to Figures 1 to 7A transmission assembly 100 of an embodiment of the utility model is used for a cleaning device 200. The transmission assembly 100 includes a first abutting member 10 and a second abutting member 12, the first abutting member 10 is connected to the second abutting member 12, and the second abutting member 12 is provided with a track surface 14, and the first abutting member 10 can be movably abutted on the track surface 14. The transmission assembly 100 is configured to connect the cleaning assembly 38 and drive the cleaning assembly 38 to rotate along a first direction and a second direction, and the first direction is opposite to the second direction. The track surface 14 includes a first area 16, a second area 18, a first connecting area 20 and a second connecting area 22. Along the second direction, the first area 16, the first connecting area 20, the second connecting area 22 and the second area 18 are connected in sequence. When the first abutting member 10 abuts against the first area 16, the cleaning assembly 38 is located in a cleaning position abutting against the ground. When the first abutting member 10 abuts against the second area 18, the cleaning assembly 38 is located in a ground-lifting position away from the ground. The slope of the second connecting area 22 is greater than the slope of the first connecting area 20.

[0094] In the above-mentioned transmission assembly 100, when the first supporting member 10 rotates from the first area 16 to the second area 18 along the second direction, the slope of the second connecting area 22 is greater than the slope of the first connecting area 20, so that the first supporting member 10 can easily reach the second area 18, and then the cleaning assembly 38 can be raised from the cleaning position to the ground position, thereby improving the accuracy of the rising of the cleaning assembly 38 and ensuring that the cleaning assembly 38 is located in the ground position.

[0095] Specifically, in some application scenarios, such as carpet cleaning, obstacle crossing, backwashing, and air drying, the cleaning device 200 may not need to perform mopping operations. If the cleaning component 38 is still in the cleaning position, the cleaning component 38 will be close to the ground. When the cleaning component 38 is close to the ground, the movement of the cleaning device 200 will cause a certain movement resistance of the cleaning device 200. Moreover, when the cleaning device 200 crosses an obstacle, the cleaning component 38 close to the ground will also increase the difficulty of crossing the obstacle.

[0096] Therefore, the cooperation between the first abutment 10 and the second abutment 12 can make the cleaning assembly 38 rise and fall relative to the base of the cleaning device 200. When the cleaning assembly 38 does not need to be attached to the ground, the cleaning assembly 38 can be raised, and when the cleaning assembly 38 needs to be attached to the ground, the cleaning assembly 38 can be lowered. In other words, the cleaning assembly 38 can be located in a cleaning position for abutting the ground and in a ground-lift position for detaching from the ground. A mop is provided on one side of the cleaning assembly 38 close to the ground.

[0097] Optionally, the cleaning device 200 includes a housing 11, and the transmission assembly 100 may be disposed on the housing 11. Figure 3, along the height direction H of the transmission assembly 100, the first abutting member 10 is located above the second abutting member 12. The second abutting member 12 includes a first ring portion 24, and the top surface of the first ring portion 24 is provided with two track surfaces 14. The second abutting member 12 can be arranged above the cleaning assembly 38 and connected to the cleaning assembly 38. The first abutting member 10 includes two push rods 26, each of which is located above a corresponding track surface 14, and the two push rods 26 are respectively abutted on the two track surfaces 14. The track surface 14 has high and low areas. When the push rod 26 abuts on the high area, the cleaning assembly 38 can be located in a cleaning position, and when the push rod 26 abuts on the low area, the cleaning assembly 38 can be located in a position off the ground. It can be understood that if the push rod 26 and the track surface 14 exchange the upper and lower positions, when the push rod 26 abuts on the high area, the cleaning assembly 38 can be located in a position off the ground, and when the push rod 26 abuts on the low area, the cleaning assembly 38 can be located in a cleaning position. It should be noted that the present solution does not specifically limit the number and relative position relationship of the track surface 14 and the push rod 26. Figure 3 In the embodiment, the first abutting member 10 moves on the track surface 14 by sliding. It is understood that in other embodiments, a roller can be added to the end of the push rod 26, and the roller contacts the track surface 14, and the first abutting member 10 moves on the track surface 14 by rolling. It is understood that the number of track surfaces 14 is not limited to two, and can also be one, or more than two, and the present invention does not specifically limit this.

[0098] Optionally, in Fig.13 In the figure, along the height direction H of the transmission assembly 100, the second abutment 12 can be located above the first abutment 10. The bottom surface of the first ring portion 24 is provided with two track surfaces 14, and the first abutment 10 can be arranged above the cleaning assembly 38 and connected to the cleaning assembly 38. The second abutment 12 can be cylindrical, and the inner side wall of the second abutment 12 can be provided with a limiting structure 28, and the limiting structure 28 can be movably abutted on the track surface 14. The track surface 14 has high and low areas. When the limiting structure 28 abuts against the high area, the cleaning assembly 38 can be located in a position off the ground. When the limiting structure 28 abuts against the low area, the cleaning assembly 38 can be located in a cleaning position. It should be noted that the utility model does not specifically limit the number and relative position relationship of the track surfaces 14 and the positioning structures. Fig.13 In the embodiment, the first abutting member 10 moves on the track surface 14 by sliding. It is understood that in other embodiments, a roller can be added to the top of the positioning structure, the roller contacts the track surface 14, and the first abutting member 10 moves on the track surface 14 by rolling.

[0099] In one embodiment, during the rotation of the first abutting member 10 from the first region 16 to the second region 18 along the second direction, the slope of the second connecting region 22 is greater than the slope of the first connecting region 20, so that the first abutting member 10 can easily reach the second region 18, thereby allowing the cleaning assembly 38 to rise from the cleaning position to the ground position, thereby improving the accuracy of the rising of the cleaning assembly 38 and ensuring that the cleaning assembly 38 is located in the ground position. It can be understood that the slope can refer to the angle between the region and the horizontal plane. Optionally, in Fig. 9 In the embodiment, the slope of the second connection area 22 may be an angle K between the second connection area 22 and a horizontal plane.

[0100] Optionally, the transmission assembly 100 includes a gear set 30, and the gear set 30 includes at least one gear. Figure 3 In the embodiment, the gear set 30 connects the driving member 36 and the first abutting member 10, and the gear set 30 transmits the power of the driving member 36 to the first abutting member 10, so that the driving member 36 can drive the first abutting member 10 to move to different areas on the track surface 14, thereby adjusting the height of the cleaning component 38 from the ground. Fig.13 and Fig.14 In the embodiment, the gear set 30 connects the driving member 36 and the second abutting member 12, and the gear set 30 transmits the power of the driving member 36 to the second abutting member 12, so that the driving member 36 can drive the second abutting member 12 to drive the track surface 14 to rotate so that the limiting structure 28 abuts against different areas on the track surface 14, thereby adjusting the height of the cleaning component 38 from the ground. The gear set 30 can be a reduction gear set 30.

[0101] Optionally, the slope of the second connection area 22 is greater than the slope of the first connection area 20, which means that if the first connection area 20 is composed of only one section, the slope of the second connection area 22 is greater than the slope of this section; if the first connection area 20 is composed of multiple sections, the slope of the second connection area 22 is greater than the average slope of the slopes of these multiple sections.

[0102] Optionally, the first direction may be a clockwise direction R1, and the second direction may be a counterclockwise direction R2. It can be understood that the present invention does not specifically limit the first direction and the second direction.

[0103] Please combine Figure 6 and Figure 7 In some embodiments, the track surface 14 includes a third area 32, and along the second direction, the first area 16, the first connection area 20, the second connection area 22, the second area 18, the second connection area 22, the first connection area 20 and the third area 32 are connected in sequence, and when the first abutting member 10 abuts against the third area 32, the cleaning component 38 is in the cleaning position.

[0104] In this way, the cleaning assembly 38 can be switched between the ground-lift position and the cleaning position through the three regions of the track surface 14 .

[0105] Specifically, in Figure 6 In the embodiment, the first area 16 and the third area 32 are located higher than the second area 18. The first abutting member 10 is located above the track surface 14. When the first abutting member 10 abuts against the first area 16 or the third area 32, the distance between the first abutting member 10 and the cleaning assembly 38 is relatively far, and the cleaning assembly 38 is located at the cleaning position. When the first abutting member 10 abuts against the second area 18, the distance between the first abutting member 10 and the cleaning assembly 38 is relatively close, and the cleaning assembly 38 is located off the ground.

[0106] Optionally, in Fig.15 In the embodiment, the first area 16 and the third area 32 are located lower than the second area 18. The first abutting member 10 is located below the track surface 14. When the first abutting member 10 abuts against the first area 16 or the third area 32, the distance between the second abutting member 12 and the cleaning assembly 38 is relatively far, and the cleaning assembly 38 is located at the cleaning position. When the first abutting member 10 abuts against the second area 18, the distance between the second abutting member 12 and the cleaning assembly 38 is relatively close, and the cleaning assembly 38 is located off the ground.

[0107] When the first abutment 10 moves from the first area 16 to the second area 18 along the second direction, the cleaning assembly 38 switches from the cleaning position to the ground position. When the first abutment 10 moves from the second area 18 to the third area 32 along the second direction, the cleaning assembly 38 switches from the ground position to the cleaning position.

[0108] When the first abutment 10 moves from the third area 32 to the second area 18 along the first direction, the cleaning assembly 38 switches from the cleaning position to the off-ground position. When the first abutment 10 moves from the second area 18 to the first area 16 along the first direction, the cleaning assembly 38 switches from the off-ground position to the cleaning position.

[0109] Please combine Fig. 9 In some embodiments, the first connection area 20 includes a plurality of first connection segments 34 connected end to end, and the slope of the second connection area 22 is greater than the slope of at least one of the plurality of first connection segments 34 .

[0110] In this way, it can be further ensured that the first abutting member 10 abuts against the second area 18, thereby improving the accuracy of the cleaning assembly 38 being located off the ground.

[0111] Specifically, in Fig. 9In the process of the first abutting member 10 rotating from the first area 16 to the second area 18, the first abutting member 10 can be rotated to the multiple first connecting segments 34, and then rotated to the second connecting area 22 through the multiple first connecting segments 34. The slope of the second connecting area 22 is greater than the slope of at least one of the multiple first connecting segments 34, so that the first abutting member 10 is easy to rotate to the second area 18, thereby ensuring that the first abutting member 10 abuts against the second area 18, ensuring that the cleaning component 38 is located off the ground.

[0112] During the process of the first abutting member 10 rotating from the third area 32 to the second area 18, the first abutting member 10 can be rotated to the multiple first connecting segments 34, and then rotated to the second connecting area 22 through the multiple first connecting segments 34. The slope of the second connecting area 22 is greater than the slope of at least one of the multiple first connecting segments 34, so that the first abutting member 10 is easy to rotate to the second area 18, thereby ensuring that the first abutting member 10 abuts against the second area 18, ensuring that the cleaning component 38 is located off the ground.

[0113] The slope of the second connection area 22 may be greater than the slope of one first connection segment 34, the slope of two first connection segments 34, the slope of another number of first connection segments 34, or the slope of all first connection segments 34. Optionally, the first connection area 20 may be one-segment type, i.e., only one first connection segment 34, or may be multi-segment type, i.e., composed of multiple first connection segments 34.

[0114] Optionally, combine Fig. 9 , the slope of the second connection area 22 is greater than the slope of at least one of the multiple first connection sections 34, the slope of the second connection area 22 is K, K≤85 degrees, K can be selected as 85 degrees, 83 degrees, 81 degrees, 79 degrees, 76 degrees, 74 degrees, 72 degrees, 70 degrees or other values ​​less than 85 degrees. The slope of the second connection area 22 can be expressed as the angle between the second connection area 22 (inclined surface) and the second area 18 (plane), and K is an acute angle. It should be noted that the size setting of the K value may be related to factors such as the friction between the first abutting member 10 and the second connection area 22, the smoothness of the second connection area 22, and the gravity of the cleaning component 38. This embodiment mainly depends on the friction between the first abutting member 10 and the second connection area 22.

[0115] Please combine Figures 2 to 5 In some embodiments, the first resisting member 10 is configured to be connected to the driving member 36, and the second resisting member 12 is configured to be connected to the cleaning assembly 38. The driving member 36 is configured to drive the first resisting member 10 to rotate along the first direction and the second direction to move the first resisting member 10 on the track surface 14, thereby causing the cleaning assembly 38 to rise and fall relative to the first resisting member 10.

[0116] In this way, the first resisting member 10 can be driven to rotate by the driving member 36, so that the second resisting member 12 drives the cleaning assembly 38 to be lifted or lowered.

[0117] Specifically, the driving member 36 may include a motor. In one embodiment, the driving member 36 may drive the first abutting member 10 to rotate in a first direction, and the first abutting member 10 may move on the track surface 14 in the first direction, so that the second abutting member 12 drives the cleaning assembly 38 to be lifted relative to the first abutting member 10. In one embodiment, the driving member 36 may drive the first abutting member 10 to rotate in a second direction, and the first abutting member 10 may move on the track surface 14 in the second direction, so that the second abutting member 12 drives the cleaning assembly 38 to be lifted relative to the first abutting member 10. For other specific descriptions, please refer to above.

[0118] Please combine Figure 6 and Figure 7 In some embodiments, a first limiting portion 40 and a second limiting portion 42 are respectively provided on the track surface 14. When the first abutting member 10 abuts against the first limiting portion 40, the first limiting portion 40 is configured to limit the end point of the movement of the first abutting member 10 on the track surface 14 along the first direction. When the first abutting member 10 abuts against the second limiting portion 42, the second limiting portion 42 is configured to limit the end point of the movement of the first abutting member 10 on the track surface 14 along the second direction.

[0119] In this way, through the two limiting portions, when the first abutting member 10 abuts against the limiting portions, the first abutting member 10 stops moving on the track surface 14 .

[0120] Specifically, when the first abutting member 10 abuts against the first limiting portion 40, the first limiting portion 40 is configured to limit the end point of the movement of the first abutting member 10 along the first direction on the track surface 14. At this time, the first abutting member 10 cannot move relative to the second abutting member 12 along the first direction. If the driving member 36 continues to drive the first abutting member 10 to rotate along the first direction, the first abutting member 10 drives the second abutting member 12 to rotate along the first direction through the first limiting portion 40, and then drives the cleaning assembly 38 to rotate along the first direction.

[0121] When the first abutting member 10 abuts against the second limiting portion 42, the second limiting portion 42 is configured to limit the end point of the movement of the first abutting member 10 along the second direction on the track surface 14. At this time, the first abutting member 10 cannot move relative to the second abutting member 12 along the second direction. If the driving member 36 continues to drive the first abutting member 10 to rotate along the second direction, the first abutting member 10 drives the second abutting member 12 to rotate along the second direction through the second limiting portion 42, and then drives the cleaning assembly 38 to rotate along the second direction.

[0122] Therefore, when the first abutting member 10 has not yet abutted against the first limiting portion 40 or the second limiting portion 42, the first abutting member 10 can be moved to different areas on the track surface 14 when rotating, thereby realizing the lifting and lowering of the cleaning assembly 38. When the first abutting member 10 abuts against the first limiting portion 40 or the second limiting portion 42, the first abutting member 10 can rotate to drive the second abutting member 12 to rotate, thereby realizing the rotation of the cleaning assembly 38.

[0123] It should be noted that when the first supporting member 10 rotates along the R1 direction, the first supporting member 10 moves along the R1 direction on the track surface 14. If the friction between the first supporting member 10 and the track surface 14 is too large, the first supporting member 10 may stay in a certain area on the track surface 14. When the friction between the cleaning component 38 and the ground is large enough and greater than the friction between the first supporting member 10 and the track surface 14, the cleaning component 38 may drive the first supporting member 10 to abut against the first limiting portion 40 through the second supporting member 12.

[0124] Furthermore, the cleaning component 38 includes a friction member (not shown). When the cleaning component 38 descends to the cleaning position, the friction member contacts the ground. The friction member can increase the friction between the cleaning component 38 and the ground, so that the friction between the cleaning component 38 and the ground is greater than the friction between the first abutment member 10 and the track surface 14. The cleaning component 38 can drive the first abutment member 10 to abut against the first limiting portion 40 through the second abutment member 12.

[0125] In certain embodiments, the transmission assembly 100 is configured as:

[0126] When the driving member 36 drives the first abutting member 10 to rotate relative to the second abutting member 12 from the second region 18 to the first region 16 along the first direction, the cleaning assembly 38 descends from the off-ground position to the cleaning position and the first abutting member 10 abuts against the first limiting portion 40;

[0127] When the driving member 36 drives the first abutting member 10 to rotate relative to the second abutting member 12 from the first area 16 to the second area 18 along the second direction, the cleaning assembly 38 rises from the cleaning position to the ground-lifting position and the first abutting member 10 is separated from the first limiting portion 40 and the second limiting portion 42;

[0128] When the driving member 36 drives the first abutting member 10 to rotate relative to the second abutting member 12 from the second area 18 to the third area 32 along the second direction, the cleaning assembly 38 descends from the off-ground position to the cleaning position and the first abutting member 10 abuts against the second limiting portion 42;

[0129] When the driving member 36 drives the first abutting member 10 to rotate from the third area 32 to the second area 18 relative to the second abutting member 12 along the first direction, the cleaning assembly 38 rises from the cleaning position to the ground position and the first abutting member 10 is separated from the second limiting portion 42 and the first limiting portion 40 .

[0130] In this way, the driving member 36 can be used to drive the rotation direction of the first resisting member 10 to achieve the first resisting member 10 resisting on different areas of the track surface 14, thereby controlling the lifting and lowering of the cleaning component 38.

[0131] Specifically, initially, the first abutting member 10 abuts against the second region 18, and the driving member 36 has not yet driven the first abutting member 10 to rotate. At this time, the cleaning assembly 38 is located in a position off the ground.

[0132] When the driving member 36 drives the first abutting member 10 to rotate from the second region 18 to the first region 16 relative to the second abutting member 12 along the first direction, the cleaning assembly 38 is lowered from the off-the-ground position to the cleaning position and the first abutting member 10 abuts against the first position-limiting portion 40. At this time, the continuous driving of the driving member 36 can cause the first abutting member 10 to drive the second abutting member 12 to rotate along the first direction through the first position-limiting portion 40, thereby driving the cleaning assembly 38 to rotate along the first direction.

[0133] When the driving member 36 drives the first abutting member 10 to rotate relative to the second abutting member 12 from the first area 16 to the second area 18 along the second direction, the cleaning assembly 38 rises from the cleaning position to the ground-lifting position and the first abutting member 10 is separated from the first limiting portion 40 and the second limiting portion 42. At this time, the first abutting member 10 cannot drive the cleaning assembly 38 to rotate through the second abutting member 12, and the cleaning assembly 38 does not rotate and is located at the ground-lifting position.

[0134] When the driving member 36 drives the first abutting member 10 to rotate relative to the second abutting member 12 from the second area 18 to the third area 32 along the second direction, the cleaning assembly 38 descends from the off-the-ground position to the cleaning position and the first abutting member 10 abuts against the second limiting portion 42. At this time, the continuous driving of the driving member 36 can make the first abutting member 10 drive the second abutting member 12 to rotate along the second direction through the second limiting portion 42, thereby driving the cleaning assembly 38 to rotate along the second direction.

[0135] When the driving member 36 drives the first abutting member 10 to rotate relative to the second abutting member 12 from the third area 32 to the second area 18 along the first direction, the cleaning assembly 38 rises from the cleaning position to the ground-lifting position and the first abutting member 10 is separated from the second limiting portion 42 and the first limiting portion 40. At this time, the first abutting member 10 cannot drive the cleaning assembly 38 to rotate through the second abutting member 12, and the cleaning assembly 38 does not rotate and is located at the ground-lifting position.

[0136] Please combine Figures 9 to 11 In some embodiments, the transmission assembly 100 is configured as follows:

[0137] In the process that the driving member 36 drives the first abutting member 10 to rotate from the first area 16 to the second area 18 along the second direction, after the first abutting member 10 rotates along the second direction by the first rotation angle, the driving member 36 drives the first abutting member 10 to perform at least one reverse rotation action;

[0138] In the process of the driving member 36 driving the first abutting member 10 to rotate from the third area 32 to the second area 18 along the first direction, the driving member 36 first drives the first abutting member 10 to rotate along the first direction by a first rotation angle, and then drives the first abutting member 10 to perform at least one reverse rotation action. The rotation angle of the reverse rotation action is the second rotation angle, and the first rotation angle is greater than the second rotation angle.

[0139] In this way, the first retaining member 10 can be kept in the second area 18, thereby allowing the cleaning assembly 38 to be located off the ground.

[0140] Optionally, in one embodiment, the rotation direction of the driving member 36 (such as a motor) is opposite to the rotation direction of the first abutting member 10. Optionally, in one embodiment, the rotation direction of the driving member 36 is the same as the rotation direction of the first abutting member 10. The utility model is not specifically limited. In addition, the rotation direction of the first abutting member 10 is the same as the rotation direction of the cleaning assembly 38, and the rotation direction of the cleaning assembly 38 is opposite to the yaw movement direction of the yaw mechanism 82.

[0141] Combination Fig. 9 In the process of the driving member 36 driving the first abutting member 10 to rotate from the first area 16 to the second area 18 along the second direction, the driving member 36 first drives the first abutting member 10 to rotate along the second direction by the first rotation angle. Due to the effect of inertia, the first abutting member 10 can rush from the second area 18 to the second connection area 22. At this time, the driving member 36 drives the first abutting member 10 to perform at least one reverse rotation action. The rotation angle of the reverse rotation action is the second rotation angle, and the first rotation angle is greater than the second rotation angle. In this way, it is ensured that the first abutting member 10 can rotate to the second area 18, thereby preventing the cleaning component 38 from falling to the cleaning position, keeping the first abutting member 10 in the second area 18, and making the cleaning component 38 located off the ground.

[0142] Optionally, in Fig.10 In the process that the driving member 36 drives the first abutting member 10 to rotate from the first area 16 to the second area 18 along the second direction, the driving member 36 drives the first abutting member 10 to perform a reverse rotation action V1, and the reverse rotation action V1 is along the first direction. Fig.11In the process that the driving member 36 drives the first abutting member 10 to rotate from the first area 16 to the second area 18 along the second direction, the driving member 36 drives the first abutting member 10 to perform two reverse rotation actions V2 and V3, and the reverse rotation action V2 is along the first direction. The reverse rotation action V3 is along the second direction. Optionally, the second rotation angle of the reverse rotation action V3 can be the same as or different from the second rotation angle of the reverse rotation action V2. Optionally, the second rotation angle of the reverse rotation action V3 is smaller than the second rotation angle of the reverse rotation action V2.

[0143] It is understood that the driving member 36 can not only drive the first abutting member 10 to perform one reverse rotation action, two reverse rotation actions, but also drive the first abutting member 10 to perform three reverse rotation actions, four reverse rotation actions or other reverse rotation actions, which are not specifically limited here. It is understood that, Fig.10 and Fig.11 It only shows the change of the rotation direction of the first abutting member 10 , and does not represent the actual movement trajectory of the first abutting member 10 .

[0144] Similarly, when the driving member 36 drives the first resisting member 10 to rotate from the third area 32 to the second area 18 along the first direction, the above understanding can be obtained.

[0145] In the process of the driving member 36 driving the first abutting member 10 to rotate from the third area 32 to the second area 18 along the first direction, the driving member 36 first drives the first abutting member 10 to rotate by a first rotation angle along the first direction. Due to the effect of inertia, the first abutting member 10 can rush from the second area 18 to the second connecting area 22. At this time, the first abutting member 10 is driven to rotate by a second rotation angle along the second direction. The first abutting member 10 can rotate from the second connecting area 22 to the second area 18, but due to the effect of inertia, the first abutting member 10 can rush from the second area 18 to the second connecting area 22. At this time, the first abutting member 10 is driven to rotate by a fifth rotation angle along the first direction. Then, by the first rotation angle being greater than the second rotation angle and the second rotation angle being greater than the fifth rotation angle, it is ensured that the first abutting member 10 can rotate to the second area 18, thereby preventing the cleaning component 38 from descending to the cleaning position and keeping the first abutting member 10 in the second area 18, so that the cleaning component 38 is located off the ground.

[0146] In some embodiments, the rotation angle of the driving member 36 corresponding to the first rotation angle is [85 degrees, 95 degrees].

[0147] In this way, it can be ensured that the driving member 36 can drive the first resisting member 10 to rotate from the first area 16 to the second area 18 or drive the first resisting member 10 to rotate from the third area 32 to the second area 18 .

[0148] Specifically, the driving member 36 may include a motor. Taking the rotation of the first abutting member 10 from the first area 16 to the second area 18 as an example, assuming that the first abutting member 10 is located in the first area 16, the corresponding rotation angle of the motor is 0 degrees. In this solution, since a transmission component such as a reduction gearbox may be provided between the driving member 36 and the first abutting member 10, the rotation angle of the driving member 36 may be inconsistent with the rotation angle of the first abutting member 10. It can be understood that in other embodiments, the rotation angle of the driving member 36 may also be the same as the rotation angle of the first abutting member 10, and the utility model does not specifically limit this.

[0149] In one embodiment, when the first abutting member 10 abuts against the first area 16, the rotation angle of the driving member 36 can be calibrated as 0 degrees. When the angle of rotation of the driving member 36 along the second direction is between 85 degrees and 95 degrees, the first abutting member 10 can be driven to rotate the first rotation angle along the second direction, thereby driving the first abutting member 10 to rotate from the first area 16 to the second area 18. In one embodiment, when the first abutting member 10 abuts against the third area 32, the rotation angle of the driving member 36 can be calibrated as 0 degrees. When the angle of rotation of the driving member 36 along the first direction is between 85 degrees and 95 degrees, the first abutting member 10 can be driven to rotate the first rotation angle along the first direction, thereby driving the first abutting member 10 to rotate from the third area 32 to the second area 18.

[0150] The rotation angle of the driving member 36 corresponding to the first rotation angle may be 85 degrees, 86 degrees, 87 degrees, 88 degrees, 89 degrees, 90 degrees, 91 degrees, 92 degrees, 93 degrees, 94 degrees, 95 degrees or other values ​​between 85 degrees and 95 degrees. The rotation angle of the mop or the driving member 36 may be detected by an angle detection device such as a code disk.

[0151] Optionally, the first rotation angle may also correspond to the rotation angle of the cleaning assembly 38. Optionally, the second rotation angle may also correspond to the rotation angle of the cleaning assembly 38. Optionally, the fifth rotation angle may also correspond to the rotation angle of the cleaning assembly 38.

[0152] In certain embodiments, the transmission assembly 100 includes a first return member 44;

[0153] When the driving member 36 drives the first abutting member 10 to rotate relative to the second abutting member 12 from the second region 18 to the first region 16 along the first direction, the first restoring member 44 is compressed by the second abutting member 12;

[0154] When the driving member 36 drives the first abutting member 10 to rotate relative to the second abutting member 12 from the first area 16 to the second area 18 along the second direction, the first restoring member 44 restores its length and drives the second abutting member 12 to drive the cleaning assembly 38 to rise from the cleaning position to the ground-lifting position;

[0155] When the driving member 36 drives the first abutting member 10 to rotate relative to the second abutting member 12 from the second region 18 to the third region 32 along the second direction, the first restoring member 44 is compressed by the second abutting member 12;

[0156] When the driving member 36 drives the first abutting member 10 to rotate relative to the second abutting member 12 from the third area 32 to the second area 18 along the first direction, the first restoring member 44 recovers its length and drives the second abutting member 12 to drive the cleaning assembly 38 to rise from the cleaning position to the ground position.

[0157] In this way, by compressing the first restoring member 44, the first restoring member 44 can be extended to drive the second abutting member 12 to drive the cleaning assembly 38 to rise, and the structure is simple.

[0158] For details, please refer to Figure 3 , a first accommodating chamber 46 is provided in the second abutting member 12, and the first resetting member 44 is located in the first accommodating chamber 46. In one embodiment, the second abutting member 12 includes a first mounting portion 48, and the first mounting portion 48 is located in the space surrounded by the first ring portion 24. The second abutting member 12 also includes a first connecting portion 50, and the first connecting portion 50 is fixedly connected to the first ring portion 24 and the first mounting portion 48, and can be rotatably connected to the cleaning assembly 38. The first mounting portion 48 and the first ring portion 24 are located at the top of the first connecting portion 50. A first accommodating chamber 46 is provided in the first mounting portion 48, and a first fixing member 52 is provided in the first accommodating chamber 46, and the first fixing member 52 may include a screw. The transmission assembly 100 includes a rotating shaft 54, and the rotating shaft 54 ​​can be connected to the gear set 30, and the rotating shaft 54 ​​is driven to rotate by the gear set 30. The rotating shaft 54 ​​passes through the first abutting member 10 and the first mounting portion 48, and one end of the rotating shaft 54 ​​extends into the first accommodating chamber 46. The rotating shaft 54 ​​is fixedly connected to the first abutting member 10, and the rotation of the rotating shaft 54 ​​can drive the first abutting member 10 to rotate. The first restoring member 44 is clamped between the upper side wall of the first accommodating cavity 46 and the first fixing member 52. Optionally, a first positioning portion 56 is provided on the upper side wall of the first accommodating cavity 46, and the first restoring member 44 is sleeved on the first positioning portion 56, so that the first restoring member 44 is more stable when compressed and extended.

[0159] When the driving member 36 drives the first abutting member 10 to rotate from the second area 18 to the first area 16 along the first direction, the second abutting member 12 descends, so that the cleaning assembly 38 descends from the off-the-ground position to the cleaning position.

[0160] When the driving member 36 drives the first supporting member 10 to rotate from the first area 16 to the second area 18 along the second direction, the first restoring member 44 restores its length, and the extended first restoring member 44 provides an upward force to the upper side wall of the first accommodating cavity 46, so that the second supporting member 12 rises, and then the cleaning assembly 38 rises from the cleaning position to the ground position.

[0161] When the driving member 36 drives the first abutting member 10 to rotate from the second area 18 to the third area 32 along the second direction, the second abutting member 12 descends, causing the cleaning assembly 38 to descend from the off-ground position to the cleaning position. The first restoring member 44 is compressed by the upper side wall of the first accommodating cavity 46, causing the first restoring member 44 to become shorter.

[0162] When the driving member 36 drives the first supporting member 10 to rotate from the third area 32 to the second area 18 along the first direction, the first restoring member 44 restores its length, and the extended first restoring member 44 provides an upward force to the upper side wall of the first accommodating cavity 46, so that the second supporting member 12 rises, and then the cleaning assembly 38 rises from the cleaning position to the ground position.

[0163] The first reset member 44 includes but is not limited to elastic members such as tension springs, torsion springs, and springs, and other reset members that can be deformed by external force and can restore the deformation when the external force is removed. The first reset member 44 shown in the figure is a tension spring.

[0164] Please combine Figure 3 and Figure 6 In some embodiments, the cleaning device 200 includes a third limiting portion 58, and a fourth limiting portion 60 is provided on the second abutting member 12. When the cleaning assembly 38 is in the cleaning position, the third limiting portion 58 and the fourth limiting portion 60 are staggered in the lifting direction of the cleaning assembly 38. When the cleaning assembly 38 is in the off-ground position, the third limiting portion 58 and the fourth limiting portion 60 abut against each other in the circumferential direction of the cleaning assembly 38.

[0165] In this way, when the third limiting portion 58 abuts against the fourth limiting portion 60 , the cleaning assembly 38 can be kept off the ground, thereby preventing the cleaning assembly 38 from rising and falling back and forth.

[0166] Specifically, the cleaning device 200 further includes a sleeve 62, and a third limiting portion 58 is convexly provided on the inner wall of the inner cavity of the sleeve 62. When the cleaning assembly 38 is located in the off-ground position, the second abutting member 12 is partially located in the inner cavity of the sleeve 62, and the third limiting portion 58 and the fourth limiting portion 60 abut against each other in the circumferential direction of the cleaning assembly 38. At this time, the first abutting member 10 abuts against the second area 18. The cleaning assembly 38 cannot rotate in the direction close to the third limiting portion 58, as shown in FIG. Figure 6Therefore, it is possible to avoid the first abutting member 10 rushing from the second area 18 to the second connecting area 22 between the second area 18 and the third area 32 and then falling on the second area 18 due to inertia when the first abutting member 10 moves from the first area 16 to the second area 18, thereby preventing the cleaning component 38 from falling and then rising. It is also possible to avoid the first abutting member 10 rushing from the second area 18 to the second connecting area 22 between the second area 18 and the first area 16 and then falling on the second area 18 due to inertia when the first abutting member 10 moves from the third area 32 to the second area 18, thereby preventing the cleaning component 38 from falling and then rising. This can make the rising action of the cleaning component 38 more stable.

[0167] When the cleaning assembly 38 is in the cleaning position, the second abutting member 12 extends out of the sleeve 62, and the third limiting portion 58 and the fourth limiting portion 60 are staggered in the lifting direction of the cleaning assembly 38. At this time, the first abutting member 10 abuts against the first area 16 or the third area 32 (at Figure 5 In the embodiment, the first abutting member 10 abuts against the third area 32). Since the third limiting portion 58 and the fourth limiting portion 60 are staggered in the lifting direction of the cleaning assembly 38, the third limiting portion 58 will not block the rotation of the cleaning assembly 38 in the rotation direction of the cleaning assembly 38, and the first abutting member 10 can drive the second abutting member 12 to rotate through the first limiting portion 40, thereby driving the cleaning assembly 38 to rotate. The staggered arrangement means that in the lifting direction of the cleaning assembly 38, the third limiting portion 58 and the fourth limiting portion 60 do not overlap and do not correspond to each other.

[0168] Please combine Figure 12 to Figure 14 In some embodiments, the second abutment 12 is configured to be connected to a driving member 36, the first abutment 10 is configured to be connected to a cleaning assembly 38, the first abutment 10 includes a limiting structure 28, the limiting structure 28 is movably abutted against the track surface 14, the driving member 36 is configured to drive the second abutment 12 to drive the track surface 14 to rotate along the first direction and the second direction relative to the limiting structure 28, and then the track surface 14 drives the first abutment 10 through the limiting structure 28 to drive the cleaning assembly 38 to rise and fall relative to the second abutment 12.

[0169] In this way, the second abutting member 12 can be driven by the driving member 36 to drive the track surface 14 to rotate relative to the limiting structure 28, so that the first abutting member 10 can be raised and lowered, and then the cleaning assembly 38 can be raised and lowered.

[0170] Specifically, in Fig.13In the height direction H of the transmission assembly 100, the second abutting member 12 can be arranged above the first abutting member 10. The first abutting member 10 can be similar to a cylindrical shape. The first abutting member 10 can be connected to the cleaning assembly 38 and arranged above the cleaning assembly 38. In one embodiment, when the limiting structure 28 abuts against the second area 18, the driving member 36 can drive the second abutting member 12 to rotate in the first direction or in the second direction, and then drive the track surface 14 to rotate in the first direction or in the second direction relative to the limiting structure 28. The track surface 14 abuts against the limiting structure 28, so that the limiting structure 28 can drive the first abutting member 10 to descend relative to the second abutting member 12, and then the cleaning assembly 38 descends relative to the second abutting member 12. In one embodiment, when the limiting structure 28 abuts against the first region 16, the driving member 36 can drive the second abutting member 12 to rotate in the first direction, thereby driving the track surface 14 to rotate in the first direction relative to the limiting structure 28, so that the limiting structure 28 can drive the first abutting member 10 to rise relative to the second abutting member 12, thereby causing the cleaning assembly 38 to rise relative to the second abutting member 12. In one embodiment, when the limiting structure 28 abuts against the third region 32, the driving member 36 can drive the second abutting member 12 to rotate in the second direction, thereby driving the track surface 14 to rotate in the second direction relative to the limiting structure 28, thereby causing the limiting structure 28 to drive the first abutting member 10 to rise relative to the second abutting member 12, thereby causing the cleaning assembly 38 to rise relative to the second abutting member 12.

[0171] Please combine Fig.15 and Fig.16 In some embodiments, a first limiting portion 40 and a second limiting portion 42 are respectively provided on the track surface 14. When the limiting structure 28 abuts against the first limiting portion 40, the first limiting portion 40 is configured to limit the end point of the moving stroke of the limiting structure 28 along the first direction on the track surface 14. When the limiting structure 28 abuts against the second limiting portion 42, the second limiting portion 42 is configured to limit the end point of the moving stroke of the limiting structure 28 along the second direction on the track surface 14.

[0172] In this way, through the two limiting parts, when the limiting structure 28 abuts against the limiting parts, the limiting structure 28 stops moving on the track surface 14 .

[0173] Specifically, when the limiting structure 28 abuts against the first limiting portion 40, the first limiting portion 40 is configured to limit the end point of the movement of the limiting structure 28 along the first direction on the track surface 14. At this time, the limiting structure 28 cannot move relative to the second abutting member 12 along the first direction. If the driving member 36 continues to drive the second abutting member 12 to rotate along the second direction, the limiting structure 28 drives the first abutting member 10 to rotate along the second direction through the first limiting portion 40, and then drives the cleaning assembly 38 to rotate along the second direction.

[0174] When the limiting structure 28 abuts against the second limiting portion 42, the second limiting portion 42 is configured to limit the end point of the movement of the limiting structure 28 along the second direction on the track surface 14. At this time, the limiting structure 28 cannot move relative to the second abutting member 12 along the second direction. If the driving member 36 continues to drive the second abutting member 12 to rotate along the first direction, the limiting structure 28 drives the first abutting member 10 to rotate along the first direction through the second limiting portion 42, and then drives the cleaning assembly 38 to rotate along the first direction.

[0175] Therefore, when the limiting structure 28 has not yet abutted against the first limiting portion 40 or the second limiting portion 42, the limiting structure 28 can be positioned at different areas on the track surface 14 when the track surface 14 rotates, so as to realize the lifting and lowering of the cleaning assembly 38. When the limiting structure 28 abuts against the first limiting portion 40 or the second limiting portion 42, the limiting structure 28 rotates again to drive the first abutting member 10 to rotate, so as to realize the rotation of the cleaning assembly 38.

[0176] It should be noted that when the second supporting member 12 rotates along the R1 direction, the limiting structure 2836 moves on the track surface 14 along the R2 direction relative to the second supporting member 12. If the friction between the track surface 14 and the limiting structure 28 is too large, the limiting structure 28 may stay in a certain area on the track surface 14. When the friction between the cleaning component 38 and the ground is large enough and greater than the friction between the track surface 14 and the limiting structure 28, the cleaning component 38 may drive the limiting structure 28 to abut against the first limiting portion 40 through the first supporting member 10.

[0177] In certain embodiments, the transmission assembly 100 is configured as:

[0178] When the limiting structure 28 abuts against the second area 18, when the driving member 36 drives the second abutting member 12 to rotate along the first direction relative to the first abutting member 10 so that the third area 32 abuts against the limiting structure 28, the first abutting member 10 drives the cleaning assembly 38 to descend from the off-the-ground position to the cleaning position and the limiting structure 28 abuts against the second limiting portion 42;

[0179] When the limiting structure 28 abuts against the third area 32, when the driving member 36 drives the second abutting member 12 to rotate relative to the first abutting member 10 along the second direction so that the second area 18 abuts against the limiting structure 28, the first abutting member 10 drives the cleaning assembly 38 to rise from the cleaning position to the ground-lifting position and the limiting structure 28 is separated from the first limiting portion 40 and the second limiting portion 42;

[0180] When the limiting structure 28 abuts against the second area 18, when the driving member 36 drives the second abutting member 12 to rotate relative to the first abutting member 10 along the second direction so that the first area 16 abuts against the limiting structure 28, the first abutting member 10 drives the cleaning assembly 38 to descend from the off-the-ground position to the cleaning position and the limiting structure 28 abuts against the first limiting portion 40;

[0181] When the limiting structure 28 abuts against the first area 16, when the driving member 36 drives the second abutting member 12 to rotate along the first direction relative to the first abutting member 10 so that the second area 18 abuts against the limiting structure 28, the first abutting member 10 drives the cleaning assembly 38 to rise from the cleaning position to the ground position and the limiting structure 28 is separated from the second limiting portion 42 and the first limiting portion 40.

[0182] In this way, the limiting structure 28 can be pressed against different areas of the track surface 14 by the rotation direction of the second pressing member 12 , thereby controlling the lifting and lowering of the first pressing member 10 and further controlling the lifting and lowering of the cleaning assembly 38 .

[0183] Specifically, initially, the limiting structure 28 can abut against the second area 18, and the second abutting member 12 has not yet driven the limiting structure 28 to rotate. At this time, the cleaning assembly 38 is located in a position off the ground. When the driving member 36 drives the second abutting member 12 to rotate relative to the first abutting member 10 along the first direction so that the third area 32 abuts against the limiting structure 28, the first abutting member 10 drives the cleaning assembly 38 to descend from the off-the-ground position to the cleaning position, and the limiting structure 28 abuts against the second limiting portion 42. At this time, the second abutting member 12 rotates along the first direction, and the limiting structure 28 moves on the track surface 14 so that the third area 32 abuts against the limiting structure 28. The continuous rotation of the second abutting member 12 can enable the limiting structure 28 to drive the first abutting member 10 to rotate along the first direction through the second limiting portion 42, and then drive the cleaning assembly 38 to rotate along the first direction.

[0184] When the limiting structure 28 abuts against the third area 32, when the driving member 36 drives the second abutting member 12 to rotate along the second direction so that the second area 18 abuts against the limiting structure 28, the first abutting member 10 drives the cleaning assembly 38 to rise from the cleaning position to the ground-lifting position, and the limiting structure 28 is separated from the first limiting portion 40 and the second limiting portion 42. At this time, the second abutting member 12 rotates along the second direction, and the limiting structure 28 moves on the track surface 14 so that the second area 18 abuts against the limiting structure 28. The limiting structure 28 cannot drive the cleaning assembly 38 to rotate through the first abutting member 10, and the cleaning assembly 38 does not rotate and is located at the ground-lifting position.

[0185] When the limiting structure 28 abuts against the second area 18, when the driving member 36 drives the second abutting member 12 to rotate in the second direction so that the first area 16 abuts against the limiting structure 28, the first abutting member 10 drives the cleaning assembly 38 to descend from the off-the-ground position to the cleaning position and the limiting structure 28 abuts against the first limiting portion 40. At this time, the second abutting member 12 rotates in the second direction, and the limiting structure 28 moves on the track surface 14 so that the first area 16 abuts against the limiting structure 28. The continuous rotation of the second abutting member 12 can enable the limiting structure 28 to drive the first abutting member 10 to rotate in the second direction through the first limiting portion 40, thereby driving the cleaning assembly 38 to rotate in the second direction.

[0186] When the limiting structure 28 abuts against the first area 16, when the driving member 36 drives the second abutting member 12 to rotate relative to the first abutting member 10 along the first direction so that the second area 18 abuts against the limiting structure 28, the first abutting member 10 drives the cleaning assembly 38 to rise from the cleaning position to the ground-lifting position, and the limiting structure 28 is separated from the second limiting portion 42 and the first limiting portion 40. At this time, the second abutting member 12 rotates along the first direction, and the limiting structure 28 moves on the track surface 14 so that the second area 18 abuts against the limiting structure 28. The limiting structure 28 cannot drive the cleaning assembly 38 to rotate through the first abutting member 10, and the cleaning assembly 38 does not rotate and is located at the ground-lifting position.

[0187] Please combine Figures 18 to 20 In some embodiments, the transmission assembly 100 is configured as follows:

[0188] When the limiting structure 28 abuts against the first region 16, during the process in which the driving member 36 drives the second abutting member 12 to rotate along the first direction so that the second region 18 abuts against the limiting structure 28, the second abutting member 12 rotates along the first direction by a third rotation angle, and then the driving member 36 drives the second abutting member 12 to perform at least one reverse rotation action;

[0189] When the limiting structure 28 abuts against the third area 32, in the process of the driving member 36 driving the second abutting member 12 to rotate along the second direction so that the second area 18 abuts against the limiting structure 28, the driving member 36 first drives the second abutting member 12 to rotate along the second direction by the third rotation angle, and then drives the second abutting member 12 to perform at least one reverse rotation action;

[0190] The rotation angle of the reverse rotation action is a fourth rotation angle, and the third rotation angle is greater than the fourth rotation angle.

[0191] In this way, the limiting structure 28 can be kept in contact with the second area 18, so that the cleaning component 38 is located off the ground.

[0192] Optionally, in one embodiment, the rotation direction of the driving member 36 (such as a motor) is opposite to the rotation direction of the second abutting member 12. Optionally, in one embodiment, the rotation direction of the driving member 36 is the same as the rotation direction of the second abutting member 12. The utility model is not specifically limited. In addition, the rotation direction of the second abutting member 12 is the same as the rotation direction of the cleaning assembly 38, and the rotation direction of the cleaning assembly 38 is opposite to the yaw movement direction of the yaw mechanism 82.

[0193] Combination Fig.18 In the process that the driving member 36 drives the second abutting member 12 to rotate along the first direction so that the second area 18 abuts against the limiting structure 28, the driving member 36 first drives the second abutting member 12 to rotate along the first direction by the third rotation angle. Due to the effect of inertia, the limiting structure 28 can rush from the second area 18 to the second connection area 22. At this time, the driving member 36 drives the second abutting member 12 to perform at least one reverse rotation action. The rotation angle of the reverse rotation action is the fourth rotation angle, and the third rotation angle is greater than the fourth rotation angle. In this way, it is ensured that the limiting structure 28 can abut against the second area 18, thereby preventing the cleaning component 38 from falling to the cleaning position, keeping the limiting structure 28 in the second area 18, and making the cleaning component 38 located off the ground.

[0194] Optionally, in Fig.19 In the process that the driving member 36 drives the second abutting member 12 to rotate along the first direction so that the second area 18 abuts against the limiting structure 28, the driving member 36 drives the second abutting member 12 to perform a reverse rotation action V4, and the reverse rotation action V4 is along the second direction. Fig. 20 In the process that the driving member 36 drives the second abutting member 12 to rotate along the first direction so that the second area 18 abuts against the limiting structure 28, the driving member 36 drives the second abutting member 12 to perform two reverse rotation actions V5 and V6, and the reverse rotation action V5 is along the second direction. The reverse rotation action V6 is along the first direction. Optionally, the fourth rotation angle of the reverse rotation action V6 can be the same as or different from the fourth rotation angle of the reverse rotation action V5. Optionally, the fourth rotation angle of the reverse rotation action V6 is smaller than the fourth rotation angle of the reverse rotation action V5.

[0195] It is understood that the driving member 36 can not only drive the second abutting member 12 to perform one reverse rotation action, two reverse rotation actions, but also drive the second abutting member 12 to perform three reverse rotation actions, four reverse rotation actions, or other number of reverse rotation actions, which are not specifically limited here. It is understood that, Fig.19 and Fig. 20 It only shows the change of the rotation direction of the second resisting member 12 , and does not represent the actual movement trajectory of the second resisting member 12 .

[0196] Similarly, when the driving member 36 drives the second abutting member 12 to rotate along the second direction so that the third area 32 abuts against the limiting structure 28 , the above can be understood.

[0197] In the process of the driving member 36 driving the second abutting member 12 to rotate along the second direction so that the third area 32 abuts against the limiting structure 28, the driving member 36 first drives the second abutting member 12 to rotate along the second direction by a third rotation angle. Due to the effect of inertia, the limiting structure 28 can abut against the second connecting area 22 from the second area 18. At this time, the second abutting member 12 is driven to rotate along the first direction by a fourth rotation angle. The limiting structure 28 can abut against the second area 18 from the second connecting area 22. However, due to the effect of inertia, the limiting structure 28 can abut against the second connecting area 22 from the second area 18. At this time, the second abutting member 12 is driven to rotate along the second direction by a sixth rotation angle. The third rotation angle is greater than the fourth rotation angle, and the fourth rotation angle is greater than the sixth rotation angle, thereby ensuring that the limiting structure 28 can abut against the second area 18, thereby preventing the cleaning component 38 from descending to the cleaning position, keeping the limiting structure 28 in the second area 18, and making the cleaning component 38 off the ground.

[0198] In some embodiments, the rotation angle of the driving member 36 corresponding to the third rotation angle is [85 degrees, 95 degrees].

[0199] In this way, it can be ensured that the driving member 36 drives the second abutting member 12 to make the limiting structure 28 abut against the second area 18 .

[0200] Specifically, taking the rotation of the second abutting member 12 to make the limiting structure 28 abut against the second region 18 from the first region 16 as an example, assuming that when the limiting structure 28 abuts against the first region 16, the corresponding rotation angle of the motor is 0 degrees. In this solution, since a transmission component such as a reduction gearbox may be provided between the driving member 36 and the second abutting member 12, the rotation angle of the driving member 36 may be inconsistent with the rotation angle of the second abutting member 12. It is understood that in other embodiments, the rotation angle of the driving member 36 may also be the same as the rotation angle of the second abutting member 12, and the utility model does not specifically limit this.

[0201] In one embodiment, when the limiting structure 28 abuts against the first region 16, the rotation angle of the driving member 36 can be calibrated as 0 degrees. When the angle of rotation of the driving member 36 along the first direction is between 85 degrees and 95 degrees, the second abutting member 12 can be driven to rotate along the first direction by a fourth rotation angle, thereby causing the limiting structure 28 to abut against the second region 18 from the first region 16. In one embodiment, when the limiting structure 28 abuts against the third region 32, the rotation angle of the driving member 36 can be calibrated as 0 degrees. When the angle of rotation of the driving member 36 along the second direction is between 85 degrees and 95 degrees, the second abutting member 12 can be driven to rotate along the second direction by a fourth rotation angle, thereby causing the limiting structure 28 to abut against the second region 18 from the third region 32.

[0202] The rotation angle of the driving member 36 corresponding to the fourth rotation angle may be 85 degrees, 86 degrees, 87 degrees, 88 degrees, 89 degrees, 90 degrees, 91 degrees, 92 degrees, 93 degrees, 94 degrees, 95 degrees or other values ​​between 85 degrees and 95 degrees. The rotation angle of the mop or the driving member 36 may be detected by an angle detection device such as a code disk.

[0203] Optionally, the third rotation angle may also correspond to the rotation angle of the cleaning assembly 38. Optionally, the fourth rotation angle may also correspond to the rotation angle of the cleaning assembly 38. Optionally, the sixth rotation angle may also correspond to the rotation angle of the cleaning assembly 38.

[0204] In certain embodiments, the transmission assembly 100 includes a second return member 64;

[0205] When the limiting structure 28 abuts against the second region 18 , when the driving member 36 drives the second abutting member 12 to rotate relative to the first abutting member 10 along the first direction so that the third region 32 abuts against the limiting structure 28 , the second restoring member 64 is compressed by the first abutting member 10 ;

[0206] When the limiting structure 28 abuts against the third area 32, when the driving member 36 drives the second abutting member 12 to rotate relative to the first abutting member 10 along the second direction so that the second area 18 abuts against the limiting structure 28, the second restoring member 64 restores its length and drives the first abutting member 10 to drive the cleaning assembly 38 to rise from the cleaning position to the ground-lifting position;

[0207] When the limiting structure 28 abuts against the second region 18, when the driving member 36 drives the second abutting member 12 to rotate relative to the first abutting member 10 along the second direction so that the first region 16 abuts against the limiting structure 28, the second restoring member 64 is compressed by the first abutting member 10;

[0208] When the limiting structure 28 abuts against the first area 16, when the driving member 36 drives the second abutting member 12 to rotate along the first direction relative to the first abutting member 10 so that the second area 18 abuts against the limiting structure 28, the second reset member 64 restores its length and drives the first abutting member 10 to drive the cleaning assembly 38 to rise from the cleaning position to the ground position.

[0209] In this way, by compressing the second restoring member 64, the second restoring member 64 can be extended to drive the first supporting member 10 to drive the cleaning assembly 38 to rise, and the structure is simple.

[0210] For details, please refer to Fig.13 , a second accommodating chamber 66 is provided in the first abutting member 10, and the second reset member 64 is located in the second accommodating chamber 66. In one embodiment, the first abutting member 10 includes a second mounting portion and a second ring portion 70, and the second mounting portion is located in the space surrounded by the second ring portion 70. The first abutting member 10 also includes a second connecting portion 72, and the second connecting portion 72 is fixedly connected to the second ring portion 70 and the second mounting portion, and can be rotatably connected to the cleaning assembly 38. The second mounting portion and the second ring portion 70 are located at the top of the second connecting portion 72. A second accommodating chamber 66 is provided in the second mounting portion, and a second fixing member 74 is provided in the second accommodating chamber 66, and the second fixing member 74 may include a screw. The transmission assembly 100 includes a rotating shaft 54, and the rotating shaft 54 ​​can be connected to the gear set 30, and the rotating shaft 54 ​​is driven to rotate by the gear set 30. The rotating shaft 54 ​​passes through the second abutting member 12 and the second mounting portion, and one end of the rotating shaft 54 ​​extends into the second accommodating chamber 66. The rotating shaft 54 ​​is fixedly connected to the second abutting member 12, and the rotation of the rotating shaft 54 ​​can drive the second abutting member 12 to rotate. The second restoring member 64 is clamped between the upper side wall of the second accommodating cavity 66 and the second fixing member 74. The rotating shaft 54 ​​can pass through the second restoring member 64.

[0211] When the limiting structure 28 abuts against the second area 18, when the driving member 36 drives the second abutting member 12 to rotate relative to the first abutting member 10 along the first direction so that the third area 32 abuts against the limiting structure 28, the first abutting member 10 descends, so that the cleaning assembly 38 descends from the off-the-ground position to the cleaning position. The second restoring member 64 is compressed by the upper side wall of the second accommodating cavity 66, so that the second restoring member 64 becomes shorter.

[0212] When the limiting structure 28 abuts against the third area 32, when the driving member 36 drives the second abutting member 12 to rotate along the second direction relative to the first abutting member 10 so that the second area 18 abuts against the limiting structure 28, the second restoring member 64 restores its length, and the extended second restoring member 64 provides an upward force to the upper side wall of the second accommodating cavity 66, so that the first abutting member 10 rises, and then the cleaning component 38 rises from the cleaning position to the ground position.

[0213] When the limiting structure 28 abuts against the second area 18, when the driving member 36 drives the second abutting member 12 to rotate relative to the first abutting member 10 along the second direction so that the first area 16 abuts against the limiting structure 28, the first abutting member 10 descends, so that the cleaning assembly 38 descends from the off-the-ground position to the cleaning position. The second restoring member 64 is compressed by the upper side wall of the second accommodating cavity 66, so that the second restoring member 64 becomes shorter.

[0214] When the limiting structure 28 abuts against the first area 16, when the driving member 36 drives the second abutting member 12 to rotate along the first direction relative to the first abutting member 10 so that the second area 18 abuts against the limiting structure 28, the second restoring member 64 restores its length, and the extended second restoring member 64 provides an upward force to the upper side wall of the second accommodating cavity 66, so that the first abutting member 10 rises, and then the cleaning component 38 rises from the cleaning position to the ground position.

[0215] The second reset member 64 includes but is not limited to elastic members such as tension springs, torsion springs, and springs, and other reset members that can be deformed by external force and can restore the deformation when the external force is removed. The second reset member 64 shown in the figure is a tension spring.

[0216] Please combine Fig.13 and Fig.17 In some embodiments, the cleaning device 200 includes a fifth limiting portion 78, and a sixth limiting portion 80 is provided on the first abutting member 10. When the cleaning assembly 38 is in the cleaning position, the fifth limiting portion 78 and the sixth limiting portion 80 are staggered in the lifting direction of the cleaning assembly 38. When the cleaning assembly 38 is in the off-ground position, the fifth limiting portion 78 and the sixth limiting portion 80 abut against each other in the circumferential direction of the cleaning assembly 38.

[0217] In this way, when the fifth limiting portion 78 abuts against the sixth limiting portion 80 , the cleaning assembly 38 can be kept off the ground, thereby preventing the cleaning assembly 38 from rising and falling back and forth.

[0218] Specifically, a fifth stopper 78 is convexly provided on the inner wall of the inner cavity of the sleeve 62. When the cleaning assembly 38 is in the off-ground position, the first abutting member 10 is partially located in the inner cavity of the sleeve 62, and the fifth stopper 78 and the sixth stopper 80 abut against each other in the circumferential direction of the cleaning assembly 38. At this time, the first abutting member 10 abuts against the second area 18. The cleaning assembly 38 cannot rotate in the direction close to the fifth stopper 78, as shown in FIG. Fig.15Therefore, it is possible to avoid the cleaning component 38 falling and rising again due to the inertia of the limiting structure 28 rushing from the second area 18 to the second connecting area 22 between the second area 18 and the third area 32 and then falling on the second area 18 when the limiting structure 28 abuts against the second area 18 from the first area 16, or to avoid the cleaning component 38 falling and rising again due to the inertia of the limiting structure 28 rushing from the second area 18 to the second connecting area 22 between the second area 18 and the first area 16 and then falling on the second area 18 when the limiting structure 28 abuts against the second area 18 from the third area 32, thereby making the rising action of the cleaning component 38 more stable.

[0219] When the cleaning assembly 38 is in the cleaning position, the first abutting member 10 extends out of the sleeve 62, and the fifth limiting portion 78 and the sixth limiting portion 80 are staggered in the lifting direction of the cleaning assembly 38. At this time, the limiting structure 28 abuts against the first area 16 or the third area 32. Since the fifth limiting portion 78 and the sixth limiting portion 80 are staggered in the lifting direction of the cleaning assembly 38, in the rotation direction of the cleaning assembly 38, the fifth limiting portion 78 will not block the rotation of the cleaning assembly 38, and the limiting structure 28 can drive the first abutting member 10 to rotate through the first limiting portion 40, thereby driving the cleaning assembly 38 to rotate.

[0220] A cleaning device 200 according to an embodiment of the present invention comprises a transmission assembly 100 according to any one of the above embodiments.

[0221] In the above-mentioned cleaning device 200, when the first supporting member 10 rotates from the first area 16 to the second area 18 along the second direction, the slope of the second connecting area 22 is greater than the slope of the first connecting area 20, so that the first supporting member 10 can easily reach the second area 18, and then the cleaning component 38 can be raised from the cleaning position to the ground position, thereby improving the accuracy of the rising of the cleaning component 38 and ensuring that the cleaning component 38 is located in the ground position.

[0222] Specifically, the cleaning device 200 includes, but is not limited to, a sweeping robot, a sweeping machine, a sweeping and mopping machine, a floor scrubber (a robot with a mopping function but no sweeping function), a double-turntable sweeping machine, a floor scrubber (such as a handheld floor scrubber, a non-handheld floor scrubber), etc. The cleaning device 200 includes a body and a mop, and the mop is mounted at the bottom of the body. When the mop of this embodiment rotates, its rotation axis is substantially perpendicular to the bottom of the body. In one embodiment, during the rotation of the first abutment 10 from the first area 16 to the second area 18 along the second direction, the slope of the second connection area 22 is greater than the slope of the first connection area 20, so that the first abutment 10 can easily reach the second area 18, thereby enabling the cleaning component 38 to rise from the cleaning position to the ground position, thereby improving the accuracy of the rising of the cleaning component 38 and ensuring that the cleaning component 38 is located at the ground position.

[0223] Please combine Figures 1 to 7 In some embodiments, the cleaning device 200 includes a housing 11, a deflection mechanism 82 and a cleaning assembly 38. The deflection mechanism 82 includes a driving member 36 and a transmission assembly 100. The transmission assembly 100 includes a first abutting member 10 and a second abutting member 12. The second abutting member 12 has a first limiting portion 40 and a second limiting portion 42. The second abutting member 12 is provided with a track surface 14. The track surface 14 includes a first area 16, a second area 18 and a third area 32. The second abutting member 12 is connected to the cleaning assembly 38. When the first abutting member 10 abuts against the first area 16 or the third area 32, the cleaning assembly 38 is located in a cleaning position for abutting against the ground. When the first abutting member 10 abuts against the second area 18, the cleaning assembly 38 is located in a ground-lifting position for leaving the ground. The deflection mechanism 82 is configured to swing on the housing 11 to a first position and a second position;

[0224] The cleaning device 200 is configured as follows:

[0225] When the first abutting member 10 is in the third area 32, the cleaning assembly 38 is in the cleaning position and the deflection mechanism 82 is in the second position, and the driving member 36 is configured to drive the cleaning assembly 38 to rotate along the second direction through the second limiting portion 42;

[0226] When the driving member 36 drives the first abutting member 10 to move from the third area 32 to the second area 18 along the first direction, the cleaning assembly 38 rises from the cleaning position to the ground-lifting position; when the driving member 36 drives the first abutting member 10 to move from the second area 18 to the first area 16 along the first direction, the cleaning assembly 38 descends from the ground-lifting position to the cleaning position, and the deflection mechanism 82 is swung from the second position to the first position by the friction torque along the second direction. The driving member 36 is configured to drive the cleaning assembly 38 to rotate along the first direction through the first limiting portion 40;

[0227] When the first abutting member 10 is in the first area 16, the cleaning assembly 38 is in the cleaning position and the deflection mechanism 82 is in the first position, and the driving member 36 is configured to drive the cleaning assembly 38 to rotate along the first direction through the first limiting portion 40;

[0228] When the driving member 36 drives the first supporting member 10 to move from the first area 16 to the second area 18 along the second direction, the cleaning component 38 rises from the cleaning position to the ground position; when the driving member 36 drives the first supporting member 10 to move from the second area 18 to the third area 32 along the second direction, the cleaning component 38 descends from the ground position to the cleaning position, and the deflection mechanism 82 swings from the first position to the second position due to the friction torque along the first direction. The driving member 36 is configured to drive the cleaning component 38 to rotate along the second direction through the second limit portion 42.

[0229] In this way, the driving member 36 can drive the first resisting member 10 to control the rotation direction of the cleaning assembly 38, thereby switching the deflection mechanism 82 between the first position and the second position.

[0230] Specifically, combined Figure 6 and Figure 7 When the first abutting member 10 abuts against the third area 32, the cleaning assembly 38 is located at the cleaning position, and the deflection mechanism 82 is located at the second position. The first position may be an outward swing position, and the second position may be an inward retracted position. When the driving member 36 drives the first abutting member 10 to rotate along the first direction, the first abutting member 10 may drive the second abutting member 12 to rotate along the first direction, and the deflection mechanism 82 swings to the first position relative to the housing 11 along the second direction. When the driving member 36 drives the first abutting member 10 to rotate along the second direction, the first abutting member 10 may drive the second abutting member 12 to rotate along the second direction, and the deflection mechanism 82 swings to the second position relative to the housing 11 along the first direction.

[0231] When the first abutting member 10 abuts against the third area 32, the cleaning assembly 38 is located at the cleaning position, and the deflection mechanism 82 is located at the second position ( FIG. Figure 5 As shown). At this time, the driving member 36 can drive the second limiting portion 42 through the first abutting member 10 to drive the cleaning assembly 38 to rotate in the second direction. When the driving member 36 drives the first abutting member 10 to move from the third area 32 to the second area 18 along the first direction, the cleaning assembly 38 rises from the cleaning position to the ground position, and the deflection mechanism 82 is still in the second position and has not swung yet. When the driving member 36 drives the first abutting member 10 to move from the second area 18 to the first area 16 along the first direction, the cleaning assembly 38 descends from the ground position to the cleaning position, and the deflection mechanism 82 is swung from the second position to the first position by the friction torque along the second direction. At this time, the driving member 36 can drive the cleaning assembly 38 to rotate in the first direction through the first limiting portion 40, and the deflection mechanism 82 is in the first position.

[0232] When the first abutment member 10 is in the first area 16, the cleaning assembly 38 is in the cleaning position, and the deflection mechanism 82 is in the first position (eg, Figure 1 As shown). At this time, the driving member 36 can drive the first limiting portion 40 through the first abutting member 10 to drive the cleaning assembly 38 to rotate in the first direction. When the driving member 36 drives the first abutting member 10 to move from the first area 16 to the second area 18 along the second direction, the cleaning assembly 38 rises from the cleaning position to the ground position, and the deflection mechanism 82 is still in the first position and has not swung. When the driving member 36 drives the first abutting member 10 to move from the second area 18 to the third area 32 along the second direction, the cleaning assembly 38 descends from the ground position to the cleaning position, and the deflection mechanism 82 is swung from the first position to the second position by the friction torque along the first direction. At this time, the driving member 36 can drive the cleaning assembly 38 to rotate in the second direction through the second limiting portion 42, and the deflection mechanism 82 is in the second position.

The deflection mechanism 82 includes a driving member 36 and a transmission assembly 100. The transmission assembly 100 includes a first abutting member 10 and a second abutting member 12. The second abutting member 12 has a first limiting portion 40 and a second limiting portion 42. The second abutting member 12 is provided with a track surface 14. The track surface 14 includes a first area 16, a second area 18 and a third area 32. The first abutting member 10 is connected to the cleaning assembly 38. When the first abutting member 10 abuts against the first area 16 or the third area 32, the cleaning assembly 38 is located in a cleaning position for abutting against the ground. When the first abutting member 10 abuts against the second area 18, the cleaning assembly 38 is located in a ground-lifting position for leaving the ground.

The driving member 36 is configured to drive the first abutting member 10 to drive the cleaning assembly 38 to rotate along the first direction through the second limiting portion 42.

[0239] In this way, the driving member 36 can drive the second resisting member 12 to control the rotation direction of the cleaning assembly 38, thereby switching the deflection mechanism 82 between the first position and the second position.

[0240] Specifically, combined Fig.15 and Fig.16 When the first abutting member 10 abuts against the third area 32, the cleaning assembly 38 is located at the cleaning position, and the deflection mechanism 82 is located at the first position.
