[0072] The technical solutions of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the present invention and the features therein may be combined with each other unless there is a conflict.

[0073] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0074] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0075] Example 1

[0076] See Figure 1 A preferred embodiment of the present invention shows a cleaning mechanism that is suitable for installation on a cleaning device so as to follow the movement of the device to clean the surface to be cleaned. In this embodiment, the cleaning device may be a sweeper, mop, sweeper-mop combination, or floor scrubber, and the surface to be cleaned may be a floor, wall, tabletop, sofa, window, or the like.

[0077] The cleaning mechanism includes a base 1 connected to the body, a cleaning assembly 3 connected to the base 1, and a second drive assembly 5 connected to the cleaning assembly 3. When the cleaning device cleans the surface to be cleaned, the second drive assembly 5 drives the cleaning assembly 3 to rotate to clean the surface to be cleaned, and the movement of the cleaning device drives the body and the cleaning assembly 3 to move, thereby achieving movable cleaning of the surface to be cleaned.

[0078] In the prior art, the cleaning member 100 on the cleaning device is usually fixed relative to the body, and due to the limitations of the cleaning device body, the cleaning member 100 has certain area limitations when performing cleaning work. For example, the cleaning member 100 cannot clean the corners of the surface to be cleaned, resulting in poor cleaning effect.

[0079] In order to solve the above problems, in this embodiment, please refer to Figure 1The cleaning assembly 3 includes a cleaning member 100. The cleaning mechanism further includes a first driving assembly 4, which is adapted to drive the cleaning member 100 to rotate relative to the base 1 so that the cleaning member 100 has an inward or outward position, thereby achieving a better cleaning effect of the cleaning member 100.

[0080] Specifically, the first drive assembly 4 includes a first drive member 43, a transmission member 41 connected to the first drive member 43, a swinging member 42 cooperating with the transmission member 41, and an actuator 421 rotatably arranged on the rotating shaft 2. Among them, the first drive member 43 is suitable for generating a driving force, and the first drive member 43 can rotate toward the first direction or toward the second direction according to the control signal. The swinging member 42 is rotatably arranged on the base 1, and the cleaning member 100 is connected to the swinging member 42 and can be rotatably connected to the base 1 through the rotating shaft 2, and the swinging member 42 is connected to the cleaning member, and the two ends of the actuator 421 act on the swinging member 42 and the transmission member 41 respectively; when the swinging member 42 cooperates with the transmission member 41, it is driven by the transmission member 41 to rotate, so as to drive the cleaning member 100 to the retracted position (please refer to Figure 3 ) and outward expansion position (please refer to Figure 2 ) When the cleaning member 100 is in normal cleaning operation (no need to clean corners), the cleaning member 100 only needs to be in the retracted position to clean the surface to be cleaned; when the cleaning device needs to clean the corners of the surface to be cleaned, the cleaning member 100 needs to move from the retracted position to the expanded position to enable the cleaning device to process the corners of the surface to be cleaned. It should be noted that in this embodiment, the cleaning member 100 is a rag disk, and the edge of the rag disk protrudes from the edge of the swinging member 42 to achieve a better cleaning effect on the surface to be cleaned.

[0081] In one embodiment, the transmission member 41 transmits the driving force of the first driving member 43 in the first direction to the actuator 421, so that the transmission member 421 rotates to drive the swinging member 42 to rotate, thereby causing the cleaning member 100 to rotate in the second direction following the swinging member 42, and then move from the retracted position to the expanded position. It should be noted that in this embodiment, during the switching process of the cleaning member from the retracted position to the expanded position, the actuator 421 stores energy due to the driving force of the transmission member 41 and drives the swinging member 42 to rotate; when the driving force applied to the transmission member 41 is removed, the actuator 421 releases the stored energy to drive the swinging member 42 to continue to swing toward the expanded position.

[0082] Specifically, the actuator 421 includes a sleeve portion 4211 sleeved on the rotating shaft 2, and a first abutting end 4212 and a second abutting end 4213 provided on the circumference of the sleeve portion 4211. The first abutting end 4212 abuts against the transmission member 41, and the second abutting end 4213 abuts against the swinging member 42, so that the first abutting end 4212 can be driven by the driving force of the transmission member 41 in the second direction to rotate around the sleeve portion 4211, thereby allowing the second abutting end 4213 to abut against the swinging member 42 for rotation, thereby allowing the cleaning member to move from the retracted position to the expanded position.

[0083] More specifically, a holding groove 411 is provided on the transmission member 41. The swing member 42 also includes a first pressing portion 4221. The above-mentioned first holding end 4212 is suitable for being held in the holding groove 41, and the second holding end 4213 cooperates with the first pressing portion 4221 to abut. When the first driving member 43 rotates toward the first direction, the first driving member 43 drives the transmission member 41 to rotate toward the second direction, and the holding groove 411 abuts the first holding end 4212, thereby driving the second holding end 4213 to rotate toward the second direction, so that the second holding end 4213 abuts the first pressing portion 4221, thereby driving the entire swing member 42 to rotate toward the second direction, and then driving the cleaning member to move from the retracted position to the expanded position.

[0084] As mentioned above, reference Figure 9 and Figure 10 The swinging member 42 also includes a second pressing portion 4222 and a supporting portion 4223 respectively arranged on both sides of the first pressing portion 4221. The cleaning member 100 is located below the supporting portion 4223 and is connected to the supporting portion 4223. The transmission member 41 also includes a supporting portion 44 that cooperates with the second pressing portion 4222 to abut against it. When the transmission member 41 is driven by the driving force of the first driving member 43 in the second direction, it rotates toward the first direction, thereby driving the supporting portion 44 to rotate around the rotating shaft 2 in the first direction, so as to support the second pressing portion 4222 to drive the swinging member 42 to rotate, so that the cleaning member moves from the expanded position to the retracted position. It is worth noting that in this embodiment, whether the cleaning member is moving from the expanded position to the retracted position or from the retracted position to the expanded position, the second pressing portion 4222 is always in abutment with the supporting portion 44.

[0085] It should be noted that in the present embodiment, the actuator 421 is an elastic member, preferably a torsion spring, which can maintain the stability of the transmission member 41 and the swing member 42 when the cleaning member 100 switches between the expanded position and the retracted position. In the present embodiment, there is one torsion spring. In other embodiments, the torsion spring can also be set to other numbers, for example, there are two torsion springs. In the present embodiment, the torsion spring has an open end and a closed end, the open end serves as the above-mentioned first abutting end 4212, which is clamped in the clamping groove 411, and the closed end serves as the above-mentioned second abutting end 4213 to cooperate with the first pressing portion 4221 of the swing member, so that the transmission member 41 transmits the driving force of the first driving member 43 to the first abutting end 4212. When the first driving member 43 overcomes the elastic force of the torsion spring, it drives the closed end to rotate around the rotating shaft 2 and presses against the first pressing portion 4221 of the swing member 42, so that the swing member 42 drives the cleaning member 100 to rotate. In other embodiments, the actuator 421 can also be set to other structures, such as a structure connected by two connecting plates and rotating around the rotating shaft 2. As long as the above-mentioned effects can be achieved, its specific structure is not specifically limited here.

[0086] In this embodiment, the purpose of setting the actuating member 421 as an elastic member is as follows: on the one hand, when the cleaning mechanism follows the movement of the machine body, the cleaning mechanism may be subjected to external forces. For example, when the cleaning mechanism is squeezed by an obstacle when it is in the expanded position or between the retracted position and the expanded position, the elastic member can play a certain buffering role on the cleaning assembly 3, preventing the cleaning assembly 3 from colliding with the base 1 and causing damage when subjected to external forces; at the same time, due to the provision of the elastic member, the elastic force will always press against the first pressing portion, so that the entire cleaning member 100 can always be pressed against the corners to complete the cleaning of the corners, and the cleaning member 100 will not be converted to the retracted position after being squeezed by external forces; on the other hand, no matter whether the cleaning member 100 rotates from the expanded position to the retracted position or from the retracted position to the expanded position, the cleaning member 100 is subjected to friction in the opposite direction of the rotation of the swing member during the transmission process. The elastic force of the elastic member can offset part of the friction generated by the cleaning member 100 during rotation, so as to improve the stability of the cleaning mechanism.

[0087] Please refer to Figure 5 and Figure 7 In this embodiment, the transmission member 41 also includes a gear portion 412 and a connecting portion 413 connected to the gear portion 412. The gear portion 412 is suitable for connecting to the first driving member 43. The abutment portion 44 is provided on the above-mentioned connecting portion 413. The first driving member 43 drives the gear portion 412 to rotate, thereby driving the connecting portion 413 to rotate to drive the first abutting end 4212 to rotate, so that the cleaning member 100 switches from the retracted position to the outward expanded position, or drives the connecting portion 413 to rotate to drive the abutment portion 44 to rotate.

[0088] When the first driving member 43 drives the gear portion 412 to rotate, it can drive the connecting portion 413 to rotate to drive the first abutting end 4212 to rotate, thereby driving the second abutting end 4213 to press the first pressing portion 4221, and then drive the cleaning member 100 to move from the expanded position to the retracted position; or, when the first driving member 43 drives the gear portion 412 to rotate, it can drive the connecting portion 413 to rotate to drive the abutting portion 44 to rotate, so that the abutting portion 44 abuts against the second pressing portion 4222, thereby driving the entire swinging member 42 to rotate, and then driving the cleaning member to move from the retracted position to the expanded position.

[0089] Furthermore, the transmission member 41 also includes a first gear 414 connected to the first driving member 43 and a second gear 415 meshing with the first gear 414. The second gear 415 includes the above-mentioned gear portion 412, the connecting portion 413 and the abutting portion 44. In this embodiment, the second gear 415 is an incomplete gear, and the setting of its circumference only needs to ensure that the cleaning member 100 can be switched between the retracted position and the expanded position. The purpose of setting the second gear 415 as an incomplete gear is to reduce the space occupied by the second gear 415. In other embodiments, the second gear 415 can also be set as a complete gear, which is not specifically limited here.

[0090] As mentioned above, in order to reasonably utilize the space and reduce the volume of the entire cleaning mechanism, in this embodiment, reference Figure 4 and Figure 8 The sleeve portion 421 includes an upper half 4214, a lower half 4215 connected to the upper half 4214, and a space formed between the upper half 4214 and the lower half 4215; the swinging member 42 includes an upper end 4224 and a lower end 4225 connected to the upper end 4224. The upper half 4214 and the lower half 4215 of the actuator 421 are alternately arranged with the upper end 4224 and the lower end 4225 of the swinging member 42, so that the actuator 421 and the swinging member 42 can be firmly connected through the rotating shaft 2, and the structure of the actuator 421, the swinging member 42 and the base 1 can be more compact.

[0091] refer to Figure 4 In the present application, the cleaning mechanism further includes a bearing 54 disposed between the rotating portion 311 and the rotating shaft 2, and a sleeve 55 disposed outside the bearing 54. The sleeve 55 is primarily used to reduce wear on the connecting portion 413 of the second gear 415 when rotating about the rotating shaft 2, while the bearing 54 can reduce the friction generated when the swinging member 42 rotates about the rotating shaft 2, thereby achieving a labor-saving effect for the first driving member 43.

[0092] refer to Figure 4The cleaning mechanism also includes a fixing assembly 6, which is suitable for fixing the rotating shaft 2 to the base 1. In this embodiment, the fixing assembly 6 includes a first fixing member 61 and a second fixing member 62, respectively provided at both ends of the rotating shaft 2. A first groove 11 and a second groove 12 adapted to the first fixing member 61 and the second fixing member 62 are respectively provided above and below the base 1. The two ends of the rotating shaft 2 extend into the first groove 11 and the second groove 12, respectively, and the two ends of the rotating shaft 2 pass through the through-holes of the first fixing member 61 and the second fixing member 62, so that the first fixing member 61 and the second fixing member 62 are respectively embedded in the first groove 11 and the second groove 12, thereby fixing the rotating shaft 2 to the base 1. In this embodiment, the first fixing member 61 is a nut embedded in the first groove 11.

[0093] To improve the stability of the rotating shaft 2 and the base 1, in this embodiment, a first step 21 is provided above the rotating shaft 2, flush with the bottom of the first groove 11. After the first fixing member 61 is inserted into the first groove 11, the bottom of the first fixing member 61 presses against the first step 21. The rotating shaft 2 is also provided with a second step 22, flush with the bottom of the second groove 12. The second fixing member 62 includes a cover plate 622 disposed within the second groove 12 and a screw 621 that passes through the cover plate 622 and is connected to the rotating shaft 2. At least a portion of the cover plate 622 is inserted into the second groove 12, so that the first protrusion 6221 of the cover plate 622 abuts against the second step 22, and the second protrusion 6222 of the cover plate 622 abuts against the end of the screw. After that, the second fixing member 62 passes through the cover plate 622, abuts against the lower end of the second protrusion 6222, and then penetrates into the rotating shaft 2, thereby locking the rotating shaft 2 and the base 1.

[0094] In this embodiment, the cleaning mechanism also includes a second drive component 5, and the second drive component 5 and the cleaning member 100 are respectively arranged above and below the support portion 312, and the second drive component 5 is connected to the cleaning member 100 to provide driving force for the cleaning member 100, thereby realizing the self-rotation of the cleaning member 100.

[0095] For more details, see Figure 6 and Figure 7The second drive assembly 5 includes a second drive member 51 and a third gear 52 connected to the second drive member 51, and a fourth gear 53 meshing with the third gear 52. The fourth gear 53 is connected to the cleaning member 100 so that the driving force generated by the second drive member 51 can be transmitted to the third gear 52 and then to the fourth gear 53, thereby driving the rotation of the cleaning member 100. It is worth noting that since the entire second drive member 51 can rotate with the swing member 42, in this embodiment, when the cleaning member 100 moves between the retracted position and the expanded position, or any position between the retracted position and the expanded position, the second drive member 51 will follow the swing member 42 in the accommodating space of the base 1. The purpose of this arrangement is that the second drive assembly 5 and the cleaning member 100 are arranged on both sides of the swing member 42, and the second drive assembly 5 does not form positional interference with the base 1 when moving, making this part of the structure compact and making rational use of space.

[0096] See Figure 11 The cleaning mechanism further includes a first detection component 7 connected to the electrical control unit signal. The first detection component 7 detects the state of the outward-expanded position of the cleaning member 100 by detecting the position of the connecting portion 413. That is, the first detection component 7 is adapted to detect whether the cleaning member 100 has reached the outward-expanded position when the cleaning member 100 moves from the retracted position to the outward-expanded position. When the cleaning member 100 moves from the retracted position to the outward-expanded position, the first detection component 7 is adapted to emit a first in-position signal. The electrical control unit receives the first in-position signal, indicating that the cleaning member 100 has reached the outward-expanded position. The electrical control unit then controls the first driving member 43 to stop operating based on the first in-position signal, that is, the first driving member 43 stops rotating in the first direction.

[0097] It is worth noting that in this embodiment, since the second gear 415 is driven by an external force to rotate the swinging member, the cleaning member 100 connected to the swinging member 42 moves between the outward-expanding position and the inward-retracting position. Therefore, in this embodiment, the first detection component 7 detects whether the cleaning member is in the outward-expanding position or the inward-retracting position by detecting the position state of the connecting portion 413. In this embodiment, the specific configuration of the first detection component 7 is as follows: the first detection component 7 includes a first transmitting member 71 and a first receiving member 72 that cooperates with the first transmitting member 71, the first transmitting member 71 is arranged on one of the side walls of the connecting portion 413 of the second gear 415 and the inner side wall of the base 1, and the first receiving member 72 is arranged on the other of the side walls of the connecting portion 413 of the second gear 415 and the inner side wall of the base 1. When the first driving member 43 drives the first gear 414 to rotate in the first direction, the gear portion 412 of the second gear 415 drives the connecting portion 413 to rotate in the second direction, thereby driving the cleaning member 100 to move from the retracted position to the expanded position. At the same time, when the first transmitting member 71 or the first receiving member 72 provided on the side wall of the connecting portion 413 rotates to the expanded position, the first transmitting member 71 transmits a first in-position signal to the first receiving member 72, and the first receiving member 72 transmits the first in-position signal to the electric control unit, which controls the first driving member 43 to stop operating. Conversely, if the first receiving member 72 cannot receive the first in-position signal emitted by the first transmitting member 71, it indicates that the cleaning member 100 is not in the expanded position, and the first driving member 43 will continue to operate in the first direction. It should be noted that in this embodiment, the photoelectric switch is preferably used for in-position detection, which is more reliable than other continuous switches.

[0098] Likewise, see Figure 12 The cleaning mechanism further includes a second detection assembly 8 connected to the electrical control unit signal. The second detection assembly 8 is adapted to detect the retracted position of the cleaning member 100 by detecting the position of the connection portion 413. That is, the second detection assembly 8 is adapted to detect whether the cleaning member 100 is in the retracted position during the process of the cleaning member 100 moving from the extended position to the retracted position. When the cleaning member 100 moves from the extended position to the retracted position, the second detection assembly 8 is adapted to transmit a second in-position signal to the electrical control unit. The electrical control unit controls the first driving member 43 to stop operating based on the second in-position signal, that is, the first driving member 43 stops rotating in the second direction.

[0099] In this embodiment, the second detection assembly 8 also detects whether the cleaning member 100 is in the extended or retracted position by detecting the position of the connecting portion 413. In this embodiment, the second detection assembly 8 is specifically configured as follows: the second detection assembly 8 includes a second emitting element 81 and a second receiving element 82 that cooperates with the second emitting element 81. The second emitting element 81 is disposed on one of the bottom of the connecting portion 413 and the inner bottom wall of the base 1, and the second receiving element 82 is disposed on the other of the bottom of the connecting portion 413 and the inner bottom wall of the base 1. When the first driving member 43 drives the first gear 414 to rotate in the second direction, the gear portion 412 of the second gear 415 cancels the driving force applied to the actuator 421. The actuator 421, under the action of its elastic force and the external force of the obstacle, switches from the outward-expanded position to the inward-retracted position. At the same time, the second transmitting member 81 or the second receiving member 82 provided on the bottom of the connecting portion 413 also rotates to the inward-retracted position. The second transmitting member 81 transmits a second in-position signal to the second receiving member 82. The second receiving member 82 transmits the second in-position signal to the electronic control unit, which controls the first driving member 43 to stop operating. Conversely, if the second receiving member 82 cannot receive the second in-position signal emitted by the second transmitting member 81, it indicates that the cleaning member 100 is not in the inward-retracted position, and the first driving member 43 will continue to rotate in the second direction. Similarly, in this embodiment, the photoelectric switch is preferably used for in-position detection, which is more reliable than other continuous switches. It is worth noting that in this embodiment, the control logic of the cleaning member between the expanded position and the retracted position is as follows: when the cleaning member moves toward the expanded position, the first drive member 43 rotates to drive the transmission member 41 and the swing member 42 to rotate. At this time, the first detection assembly 7 is suitable for detecting the position of the transmission member 41, but not the position of the cleaning member. When the transmission member 41 reaches the preset position, that is, the cleaning member reaches the expanded position, the first drive member 43 stops rotating. Because a torsion spring is provided between the swing member 42 and the transmission member 41, the torsion spring also drives the cleaning member to swing outward. The outward swing angle of the cleaning member is uncertain, depending on whether the cleaning member is hit by external obstacles or walls and the force applied to the torsion spring. When the cleaning member moves toward the retracted position, the theoretical time required for the first drive member 43 to drive the cleaning member to swing inward by A° is t1. However, in practice, due to the tolerance in the transmission process of the first gear and the second gear, when actually controlling the retraction, the actual driving time of the motor is t1 + t2. During the time t2, the cleaning member continues to retract, which can offset the tolerance of the transmission of the first gear and the second gear. During the retraction process, the second detection component detects the position of the transmission member 41. Since the transmission member and the swing member 42 are in hard contact, when the second detection component detects that the cleaning member is in the retracted state, the first drive member 43 will continue to run for t2. When t2 expires, the first drive member 43 stops. (That is, the retracted position is first detected, and then the motor continues to rotate for t2). In this embodiment, t2 = 0-5 seconds, preferably 2 seconds. In this application, please refer to Figure 1 and Figure 6 , the cleaning mechanism also includes a first shock absorbing assembly 9, which is suitable for preventing the cleaning assembly 3 from colliding with the base 1 when it rotates from the outward-expanded position to the inward-retracted position. Specifically, the first shock absorbing assembly 9 includes a first shock absorbing member 91 provided on the second driving assembly 5, and the base 1 includes a first abutting portion 13. When the cleaning member 100 is in the retracted position, the first shock absorbing member 91 contacts the first abutting portion 13, and there is a gap between the cleaning assembly 3 and the base 1 in the horizontal direction. It can also be understood that when the cleaning member 100 is in the retracted position, only the first shock absorbing member 91 contacts the base 1, and other parts do not contact the base 1, so as to prevent the cleaning mechanism from colliding with the base 1.

[0100] The cleaning mechanism also includes a second shock-absorbing assembly 10, which is suitable for preventing the cleaning assembly 3 from colliding with the base 1 when it rotates from the retracted position to the expanded position. Specifically, the second shock-absorbing assembly 10 includes a second shock-absorbing member 101 arranged on the second driving assembly 5, and the base 1 includes a second abutting portion 14 arranged on the inner wall. When the cleaning member 100 is in the expanded position, the second shock-absorbing member 101 contacts the second abutting portion 14, and in the horizontal direction, there is a gap between the cleaning assembly 3 and the inner wall of the base 1. It can also be understood that when the cleaning member 100 is in the expanded position, only the second shock-absorbing member 101 contacts the inner wall of the base 1, and other parts do not contact the base 1, thereby preventing the cleaning mechanism from colliding with the inner wall of the base 1. It should be noted that in this embodiment, the first shock-absorbing member 91 and the second shock-absorbing member 101 are both configured to be made of silicone material.
