Embodiments of the present application

[0034] In order to make the person skilled in the art to which the present disclosure belongs more clearly understand the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by the person skilled in the art without creative labor are within the scope of protection of the present disclosure.

[0035] The sweeping robot belongs to a cleaning intelligent mobile product. When performing a cleaning task, the sweeping robot mainly relies on a middle roller brush to roll up dust on the ground, and relies on air flow generated by a fan in a main machine to suck the dust into a dust box. Since the roller brush has a limited coverage area in operation, two cleaning assemblies are arranged at positions on both sides of the front roller brush of the sweeping robot. The cleaning assemblies gather dust on both sides of the roller brush to the coverage area of the roller brush, so as to facilitate cleaning of the roller brush, and to increase the coverage area of the sweeping robot during cleaning, so as to expand the cleaning range and improve the cleaning efficiency.

[0036] In the related art, the sweeping robot arranges one or two cleaning assemblies at the bottom of the machine. The cleaning assemblies are fixed on a chassis. In operation, the side brushes of the cleaning assemblies are always in a rotating state. When the machine climbs over an obstacle or climbs over a carpet, or cleans a sanitary corner, the cleaning assemblies hinder the machine from climbing or rolling up the carpet, so that the machine cannot clean in some specific scenarios, which affects the cleaning efficiency and user experience.

[0037] Based on the above technical problems, the present disclosure provides a cleaning module, a cleaning device and a cleaning system, so that the cleaning device can clean in specific scenarios, thereby improving the cleaning efficiency and user experience.

[0038] FIG. 1 shows a state diagram of a cleaning module in a cleaning position in one or more embodiments of the present disclosure, and FIG. 2 shows a state diagram of the cleaning module shown in FIG. 1 in a retracted position. Referring to FIG. 1 and FIG. 2, the design idea of the present disclosure is to control the reciprocating rotation of the cleaning assembly 4 of the cleaning module, so as to switch the cleaning assembly 4 between the cleaning position and the retracted position, so as to meet the cleaning work of the machine in different scenarios, thereby improving the cleaning efficiency and user experience. The specific technical solutions will be described in detail below with reference to the accompanying drawings.

[0039] FIG. 3 shows a transmission structure diagram of FIG. 1, and FIG. 4 shows a transmission structure diagram of FIG. 2. For clarity, the top of the base is omitted in FIG. 3 and FIG. 4. Referring to FIG. 3 and FIG. 4, the cleaning module of the present disclosure includes a power assembly 1, a swing arm 2, a support shaft 3 and a cleaning assembly 4. In some embodiments, the power assembly 1 is provided with a reciprocating swing actuating portion 101, the swing arm 2 has an actuating end 201 and a connecting end 202, the actuating end 201 is connected with the actuating portion 101, and the connecting end 202 is connected with the support shaft 3. The swing arm 2 drives the support shaft 3 to reciprocate under the drive of the actuating portion 101. The cleaning assembly 4 is connected with the support shaft 3 to reciprocate synchronously with the support shaft 3, so as to switch between the cleaning position and the retracted position.

[0040] According to the cleaning module provided by the present disclosure, since the power assembly 1 is provided with the reciprocating swinging driving part 101, the driving end 201 of the swing arm 2 is connected with the driving part 101, and the connecting end 202 of the swing arm 2 is connected with the support shaft 3, therefore, the swing arm 2 can drive the support shaft 3 to reciprocate under the driving of the driving part 101. Since the cleaning assembly 4 is connected with the support shaft 3, under the reciprocating condition of the support shaft 3, the cleaning assembly 4 and the support shaft 3 can be driven to reciprocate synchronously, so that the cleaning assembly 4 can be switched between the cleaning position and the retracted position, so that the cleaning assembly 4 of the cleaning module can be switched to the retracted position in the special scene that the machine climbs over the carpet or cleans the sanitary inside corner, so that the cleaning equipment can normally operate, and the cleaning efficiency and user experience are improved. The specific technical solutions of the cleaning module will be described in detail below based on the drawings.

[0041] Referring to FIGS. 3 and 4, the cleaning module of the present disclosure comprises a base 5 provided with a receiving cavity 501, and the first driving member 102 can be a driving motor which is arranged below the base 5, and the output part of the first driving member 102 is assembled into the receiving cavity 501 of the base 5 through the bottom of the base 5.

[0042] FIG. 5 shows the internal schematic view of the base in FIG. 3, and FIG. 6 shows the internal schematic view of the base in FIG. 5. Referring to FIGS. 5 and 6, the power assembly 1 of the present disclosure comprises a first driving member 102, a first transmission member 103, and a driving member 104, the first driving member 102 has a rotatable output part, the first transmission member 103 is in transmission connection with the output part of the first driving member 102; the driving member 104 is connected with the first transmission member 103, and the driving member 104 is configured as the driving part 101.

[0043] Referring to FIGS. 5 and 6, in an embodiment, the first transmission member 103 is arranged in the receiving cavity 501 of the base 5, and the first transmission member 103 comprises a first gear 1031 and a second gear 1032. In some embodiments, the first gear 1031 is assembled on the output part of the first driving member 102, the second gear 1032 is in meshing connection with the first gear 1031, and the driving member 104 is connected with the circumferential side of the second gear 1032, so that under the working condition of the first driving member 102, the second gear 1032 is driven to rotate by the first gear 1031, and then the driving member 104 rotates synchronously with the second gear 1032. In some embodiments, the radius of the first gear 1031 is preferably smaller than the radius of the second gear 1032, so that the second gear 1032 can rotate at a lower speed, so as to reduce the swing speed of the cleaning assembly 4 and improve the stability of the swing of the cleaning assembly 4. In another embodiment, the first transmission member 103 can only comprise the first gear 1031, and the driving member is connected with the circumferential side of the first gear 1031.

[0044] Figure 7 shows a structural schematic diagram of the second gear in Figure 5 or Figure 6. Referring to Figure 7, since the actuating part 101 of the power assembly 1 is reciprocatingly swung, the rotation angle of the second gear 1032 is limited, and in an embodiment, the second gear 1032 can be provided as a sector. In some embodiments, the heart part is sleeved on the rotating shaft on the base 5 to reduce the space occupied by the second gear 1032 under the premise that the second gear 1032 and the first gear 1031 are meshingly connected and drive the actuating part 104 to reciprocatingly swing. In another embodiment, the first gear 1031 can also be designed as a sector. Alternatively, both the first gear 1031 and the second gear 1032 are sectors, which can also reduce the space occupied by the first transmission part 103 under the premise that the second gear 1032 and the first gear 1031 are meshingly connected and drive the actuating part 104 to reciprocatingly swing.

[0045] Figure 8 shows a structural schematic diagram of the base in Figure 5 or Figure 6. Referring to Figure 7 and Figure 8, the base 5 can be provided with a guide groove 502 at a position for supporting the second gear 1032, and the second gear 1032 is provided with a guide part 1033 movably connected in the guide groove 502, under the condition that the second gear 1032 is driven by the first gear 1031 to reciprocatingly swing, the guide part 1033 moves in the guide groove 502 to make the second gear 1032 rotate smoothly. In an embodiment, the guide groove 502 can be relatively provided with two sections, and the second gear 1032 is provided with a guide block at two side edges. The bottom of the guide block protrudes from the bottom of the second gear 1032 and is movably inserted into the corresponding guide groove 502. Under the condition that the second gear 1032 is driven by the first gear 1031 to reciprocatingly swing, the guide block moves in the guide groove 502, and the guide block is configured as the guide part 1033. In another embodiment, the guide groove can also be provided with a section, and the guide block is provided at one side edge of the second gear 1032. Alternatively, the guide block is provided at the bottom of the second gear 1032, which is not limited here.

[0046] Referring to Figures 3-6, the cleaning module of the present disclosure further comprises a position confirming part 6 to confirm that the cleaning assembly 4 is in a cleaning position or a retracted position. In an embodiment, the position confirming part 6 is provided with two, respectively confirming that the cleaning assembly 4 is in a cleaning position or a retracted position.

[0047] Fig. 9 shows a schematic view of the structure of the position confirming member, and Fig. 10 shows a schematic view of the assembly of the position confirming member and the second gear. Referring to Figs. 9 and 10, in a specific implementation, the position confirming member 6 can include light interruption sensors. Two position confirming members 6 can be connected to a mounting plate 7 by buckling or the like. The mounting plate 7 can be assembled to the inner side of the top of the base 5. Two housings can be spaced apart around the central axis of the second gear 1032. The light shielding members are arranged on the second gear 1032 to rotate synchronously with the second gear 1032. For example, the light shielding members can be the guide blocks described above to reduce the number of components and simplify the structure. The light shielding members and the housings are arranged one-to-one. Two light shielding members pass through the corresponding housings to form detection confirmation of two position attitudes. According to another embodiment of the present disclosure, the position confirming member 6 can also be a contact switch or the like. The contact switch can be connected to the side wall of the accommodating cavity 501 of the base 5 by buckling or the like. The contact switch is arranged on both sides of the swing space of the swing arm 2. The swing arm 2 serves as a trigger 1202 to trigger the corresponding position confirming member 6 when the cleaning assembly 4 is in different positions to form detection confirmation of two positions.

[0048] Fig. 11 shows a schematic view of the structure of the swing arm. Referring to Fig. 11, the swing arm 2 of the present disclosure can have a rod-like structure. The swing arm 2 is arranged on the bottom of the accommodating cavity 501 of the base 5. The size of the actuating end 201 of the swing arm 2 is preferably smaller than the size of the connecting end 202 to reduce the range of the swing space formed by the swing of the swing arm 2 and reduce the occupied space.

[0049] Referring to Figs. 5 and 6, the cleaning module further includes two anti-collision members 8 arranged on both sides of the swing space of the swing arm 2. When the swing arm 2 swings to the limit position, the swing arm 2 contacts the anti-collision members 8 to reduce noise and limit the rotation position of the swing arm 2. In a specific implementation, the anti-collision member 8 can have a block structure made of an elastic material. The anti-collision member 8 can be connected to the side wall of the accommodating cavity 501 of the base 5 by buckling, insertion or adhesion, which is not limited herein.

[0050] Fig. 12 shows a schematic view of the structure of the swing arm in another view of Fig. 11. Referring to Fig. 12, in an embodiment, the bottom of the connecting end 202 of the swing arm 2 can be provided with a connecting groove 203. The top end gap of the support shaft 3 passes through the bottom of the base 5 and is inserted into the connecting groove 203 of the connecting end 202 of the swing arm 2. The support shaft 3 and the connecting end 202 of the swing arm 2 are connected by screws or the like. In another embodiment, the bottom of the connecting end 202 of the swing arm 2 can be provided with a gap that passes through the bottom of the base 5. The support shaft 3 and the connecting end 202 of the swing arm 2 are connected by screws or the like, which is not limited herein.

[0051] Figure 13 shows a schematic view of the cavity structure assembled by the base, the support base and the pedestal of the cleaning module. Referring to Figure 13, in an embodiment, the cleaning module further comprises a base 9 and a support base 10, the base 9 is disposed below the pedestal 5, and the base 9 and the pedestal 5 are connected by the support base 10 between the side portions of the base 9 and the pedestal 5 to form a cavity structure with an opening. The two ends of the support shaft 3 are rotatably connected to the base 9 and the pedestal 5, respectively, and the cleaning assembly 4 is connected to the support shaft 3 to swing reciprocally in the cavity structure to switch between the cleaning position and the retracted position.

[0052] Referring to Figures 3-6, according to an embodiment of the present disclosure, the pushing end 201 of the swing arm 2 is detachably abutted against the pushing portion 101. When the cleaning assembly 4 is in the cleaning position, the pushing end 201 of the swing arm 2 is disposed at the side of the pushing portion 101 of the power assembly 1, and under the condition that the pushing portion 101 of the power assembly 1 is rotated in a certain direction (for example, counterclockwise), the driving swing arm 2 drives the support shaft 3 to rotate in the opposite direction (for example, clockwise), and in turn drives the cleaning assembly 4 connected to the support shaft 3 to rotate in the opposite direction (for example, clockwise) to switch the cleaning assembly 4 to the retracted position.

[0053] Referring to Figure 5, when the cleaning assembly 4 is in the retracted position, the end of the pushing portion 101 abuts against the side of the pushing end 201 of the swing arm 2, and the radial direction of the contact position between the pushing portion 101 and the pushing end 201 on the pushing portion 101 and the side of the swing arm 2 facing the pushing portion 101 form an angle a, which is less than or equal to 90°. At this time, the first driving member 102 can be controlled to stop working, and the supporting force of the pushing portion 101 on the swing arm can keep the cleaning assembly 4 in the retracted position to reduce energy consumption. The radial direction of the contact position between the pushing portion 101 and the pushing end 201 on the pushing portion 101 refers to the connection between the contact position between the pushing portion 101 and the pushing end 201 and the central axis of the second gear 1032, and the side of the swing arm 2 facing the pushing portion 101 is a plane.

[0054] Referring to FIG. 1 and FIG. 3, in order to switch the cleaning assembly 4 from the retracted position to the cleaning position, the cleaning module of the present disclosure further comprises a reset member 11. The reset member 11 is arranged between the support seat 10 and the cleaning assembly 4. During the rotation of the driving portion 101 of the power assembly 1, the swing arm 2, the support shaft 3 and the cleaning assembly 4, the reset member 11 is compressed and deformed. When it is needed to switch the cleaning assembly 4 from the retracted position to the cleaning position, the driving portion 101 of the power assembly 1 is first controlled to rotate reversely (for example, in the clockwise direction) so that the included angle a is greater than 90°, and then the cleaning assembly 4 is switched to the cleaning position by the restoring force of the deformation of the reset member 11. At this time, the power assembly 1, the swing arm 2 and the support shaft 3 all return to the corresponding positions, and the cleaning assembly 4 is kept in the cleaning position by the supporting force of the reset member 11. At the same time, when the cleaning equipment is working, if an external object touches the cleaning assembly 4, the reset member 11 can also buffer the cleaning assembly 4, thereby improving the service life of the cleaning assembly 4.

[0055] FIG. 14 shows an assembly diagram of the swing portion and the swing arm of the cleaning module in the cleaning position in another embodiment, FIG. 15 shows an assembly diagram of the swing portion and the swing arm of the cleaning module in the retracted position in another embodiment, and FIG. 16 shows an exploded diagram of the swing portion and the swing arm in FIG. 14. Referring to FIG. 14-FIG. 16, according to another embodiment of the present disclosure, the end of the swing portion 101 is provided with a first connecting portion 105, the end of the swing arm 2 is provided with a second connecting portion 204, and the first connecting portion 105 and the second connecting portion 204 are connected. In some embodiments, one of the first connecting portion 105 and the second connecting portion 204 is a connecting hole, and the other is a connecting piece which can move in the length direction of the connecting hole. When the cleaning assembly 4 is in the cleaning position, the swing end 201 of the swing arm is arranged at the side of the swing portion 101 of the power assembly 1. Under the condition that the swing portion 101 of the power assembly 1 rotates in a certain direction (for example, counterclockwise), the connecting piece moves in the length direction of the connecting hole. At the same time, the swing arm 2 is driven to rotate the support shaft 3 in the opposite direction (for example, clockwise), and then the cleaning assembly 4 connected to the support shaft 3 is driven to rotate in the opposite direction (for example, clockwise) to switch the cleaning assembly 4 to the retracted position. When the cleaning assembly 4 is switched from the retracted position to the cleaning position, the swing portion 101 of the power assembly 1 is controlled to rotate reversely (for example, in the clockwise direction), and the connecting piece moves reversely in the length direction of the connecting hole. At the same time, the swing arm 2 is driven to rotate the support shaft 3 (for example, counterclockwise), and then the cleaning assembly 4 connected to the support shaft 3 is driven to rotate (for example, counterclockwise) to switch the cleaning assembly 4 to the cleaning position.

[0056] Referring to FIG. 16, in an embodiment, the first connecting part 105 on the toggle part 101 can be the connecting piece described above, which can be a connecting shaft or the like, and the second connecting part 204 on the toggle arm 2 can be the connecting hole described above, which can be a waist round hole or a rectangular hole. In another embodiment, the first connecting part 105 and the second connecting part 204 can also be switched with each other, i.e., the first connecting part 105 can be the connecting hole described above, and the second connecting part 204 can be the connecting piece described above, which is not limited here.

[0057] In the embodiment in which the position switching of the cleaning assembly 4 is realized by the two cooperating connecting parts, the cleaning assembly can also include the reset piece 11 described above. Although the reset piece 11 also deforms correspondingly during the position switching of the cleaning assembly 4, its main function is to buffer the touch of external objects on the cleaning assembly 4, thereby improving the service life of the cleaning assembly 4. The assembly details of the reset piece 11 are further described below based on the drawings.

[0058] FIG. 17 shows a structural schematic diagram of the side brush housing of the cleaning assembly. Referring to FIG. 17, the cleaning assembly 4 includes a side brush housing 401, and the top and bottom of the side brush housing 401 are respectively provided with a first sleeve part 402 and a second sleeve part 403, which can be annular structures and are rotatably connected to the support shaft 3. FIG. 18 shows a structural schematic diagram of the reset piece, and FIG. 19 shows an assembly schematic diagram of the reset piece shown in FIG. 18. Referring to FIGS. 17-19, the reset piece 11 can be a torsion spring, which is placed on the support shaft 3 between the first sleeve part 402 and the second sleeve part 403. The reset piece 11 has two free ends, i.e., a first free end 1101 and a second free end 1102. The first free end 1101 can be provided with two, which are connected to the side wall of the support seat 10, and the second free end 1102 can abut against the inner side of the cleaning assembly 4 to deform correspondingly during the position switching of the cleaning assembly 4.

[0059] It should be noted that the switching action of the cleaning assembly 4 described above can also be reversed. For example, the cleaning assembly 4 is switched from the retracted position to the cleaning position by the force of the toggle part 101 of the power assembly 1, and the cleaning assembly 4 is switched from the cleaning position to the retracted position by the deformation recovery force of the elastic piece. For details, reference can be made to the description above, which is not repeated here.

[0060] Fig. 20 shows a schematic diagram of the transmission structure of the cleaning assembly. Referring to Fig. 20, the cleaning assembly 4 of the present disclosure further comprises a second driving member 404, a worm gear mechanism 405, a second transmission member 406 and a cleaning mechanism. In some embodiments, the second driving member 404 is arranged in a horizontal direction and has a rotatable output end, the input part of the worm gear mechanism 405 is connected to the output end of the second driving member 404, and the output part of the worm gear mechanism 405 is connected to the input shaft of the cleaning mechanism through the second transmission member 406. According to the cleaning assembly 4 shown in the present disclosure, since the second driving member 404 is arranged in a horizontal direction and is connected to the worm gear mechanism 405, the horizontal space of the cleaning assembly 4 can be reduced, which is conducive to the arrangement of the remaining parts of the cleaning device. The cleaning assembly 4 may, to some extent, increase the thickness of the cleaning assembly 4, but can utilize the internal space of the cavity structure formed by the base 9, the base 5 and the support seat 10, and does not interfere with the arrangement of the remaining parts of the cleaning device, which has good practicability. The specific structure of the cleaning assembly 4 will be further described based on Fig. 20.

[0061] Referring to Fig. 20, the second driving member 404, the worm gear mechanism 405 and the second transmission member 406 are all arranged in the brush housing 401. In some embodiments, the second driving member 404 can also be a motor, the worm sleeve of the worm gear mechanism 405 is arranged on the output part of the second driving member, and the worm is rotatably connected to a rotating shaft. The second transmission member 406 can comprise a third gear which is in meshing transmission with the worm, and the brush member is arranged below the brush housing 401, the rotating shaft of the brush member passes through the bottom of the brush housing 401 and is connected to the middle part of the third gear. When the cleaning assembly 4 needs to work, the second driving member 404 is controlled to start, so as to drive the third gear to rotate through the worm gear mechanism 405, and then drive the brush member to rotate.

[0062] Referring to Figs. 2 and 4, the cleaning module further comprises an anti-collision mechanism 12 which is connected to the side of the cleaning assembly 4. When the anti-collision mechanism collides with an obstacle, a trigger signal is generated to control the cleaning assembly 4 to retract inwardly, so that the machine can normally travel.

[0063] Fig. 21 shows a schematic view of the anti-collision mechanism in Figs. 2 and 4, and Fig. 22 shows a combined schematic view of the anti-collision mechanism in Fig. 21.
