Description

Technical Field

[0001] The present invention relates to the technical field of cleaning robot accessories, and in particular provides a cleaning base station. Background Art

[0002] At present, with the improvement of living standards, more and more consumers choose to use machines to complete tedious housework. Among them, intelligent sweeping robots are very popular among consumers.

[0003] The common sweeping and mopping robots currently available on the market that can realize wet mopping function usually include a sweeping roller brush and a flat mop, which can clean the floor independently or in combination.

[0004] However, after use, the flat mop of the sweeping and mopping robot is generally cleaned manually or directly replaced with a new flat mop, resulting in a poor user experience. Summary of the Invention

[0005] The purpose of the embodiments of the present application is to provide a cleaning base station, aiming to improve the problem that the flat mop of a sweeping and mopping robot is difficult to clean or has low cleaning efficiency.

[0006] To achieve the above objectives, the technical solutions adopted in the embodiments of the present application are:

[0007] In a first aspect, an embodiment of the present application provides a cleaning base station, including:

[0008] base;

[0009] A front shell, the front shell being arranged on the base and having an opening for the cleaning robot to enter and exit;

[0010] A mop cleaning mechanism, comprising a drive assembly, a guide assembly disposed opposite the drive assembly, a connecting bracket for connecting the drive assembly and the guide assembly, and a cleaning assembly, wherein the cleaning assembly comprises a shower assembly, a brush rod rotatably connected to the shower assembly, and a power active portion and a sliding driven portion fixedly connected to opposite ends of the shower assembly, respectively, the output end of the power active portion being connected to the brush rod, and the power active portion and the sliding driven portion being slidably connected to the drive assembly and the guide assembly, respectively;

[0011] Wherein, the driving assembly is used to drive the shower assembly and the brush rod to reciprocate linearly along the guide direction of the guide assembly.

[0012] The beneficial effects of the embodiments of the present application are as follows: After the cleaning robot completes its cleaning task, it enters the cleaning base station through the opening of the front shell. Furthermore, the mop of the cleaning robot faces the base and is located above the shower assembly and brush rod of the mop cleaning mechanism. The drive assembly of the mop cleaning mechanism drives the active power part to move relative to it, while the sliding driven part follows the active power part to move relative to it on the guide assembly. Since the drive assembly and the guide assembly are arranged relative to each other, the shower assembly and the roller brush perform reciprocating linear motion on the mop. At the same time, the roller brush can also be powered by the active power part to rotate around its axis, that is, while performing reciprocating linear motion on the mop, the roller brush also rotates around its axis. The cleaning base station provided by the embodiments of the present application can simultaneously spray and clean the mop with the shower assembly and roller brush it with the brush rod, thereby significantly improving the cleaning efficiency of the cleaning robot's mop.

[0013] In some embodiments, the driving assembly includes a power unit and a synchronous transmission unit connected to an output end of the power unit, and the synchronous transmission unit is connected to the power active unit.

[0014] By adopting the above technical solution, the power source is provided by the power unit, for example, the power unit can be a motor, a telescopic cylinder, a hydraulic cylinder, etc., and the synchronous transmission unit is used to transmit the torque to the power active unit, thereby driving the power active unit to perform reciprocating linear movement.

[0015] In some embodiments, the power unit includes a driving motor, the synchronous transmission unit includes a first pulley connected to the output end of the driving motor, a second pulley arranged at an interval from the first pulley, and a synchronous belt wound around the first pulley and the second pulley, and the synchronous belt is connected to the power active unit.

[0016] By adopting the above technical solution, the driving motor provides a power source and outputs torque to the first pulley to drive the first pulley to rotate. The first pulley drives the second pulley to rotate through the synchronous belt. In this way, the synchronous belt is transmitted back and forth between the first pulley and the second pulley, and finally drives the power active part to perform reciprocating linear motion.

[0017] In some embodiments, the drive assembly also includes a drive housing and two collision switches disposed in the drive housing and used to contact and collide with the power active part. Each of the collision switches is electrically connected to the drive motor, one of the collision switches is disposed close to the first pulley, and the other collision switch is disposed close to the second pulley.

[0018] By adopting the above technical solution, when the power active part performs reciprocating linear movement, it can touch the corresponding collision switch when it moves to the two extreme positions, so as to adjust the direction of the drive motor through the relative collision switch, so that the power active part can perform reciprocating linear movement.

[0019] In some embodiments, the guide assembly includes a guide shell connected to the connecting bracket and a first guide shaft arranged in the guide shell. The sliding follower is provided with a first through hole for the first guide shaft to pass through, so that the sliding follower is slidably connected to the first guide shaft.

[0020] By adopting the above technical solution, the sliding follower is penetrated by the first guide shaft so as to slide relative to the guide assembly.

[0021] In some embodiments, the power active part includes a box body and a power source provided on the box body, and an output end of the power source is connected to the brush rod.

[0022] By adopting the above technical solution, the power source can be various types of motors, and the power source can directly or indirectly output torque to the brush rod to drive the brush rod to rotate around the axis, that is, the rotation of the brush rod around the axis and the reciprocating linear movement of the brush rod are independent of each other and do not interfere with each other.

[0023] In some embodiments, the power active part includes a housing and an acceleration gear set arranged in the housing, the driving assembly is provided with a rack, the first gear of the acceleration gear set is meshed and connected with the rack, and the last gear of the acceleration gear set is connected to the brush rod.

[0024] By adopting the above technical solution, when the housing and the acceleration gear set move back and forth linearly relative to the driving assembly, the first gear of the acceleration gear set meshes with the rack, and the last gear of the acceleration gear set provides rotational torque for the brush rod. That is, the rate of reciprocating linear movement of the brush rod affects the rate of rotation of the brush rod around the axis. Specifically, the faster the rate of reciprocating linear movement of the brush rod, the faster the rate of rotation of the brush rod around the axis.

[0025] In some embodiments, the driving assembly is provided with a second guide shaft, and the box body is provided with a second through hole for the second guide shaft to pass through, so that the box body is slidably connected to the second guide shaft.

[0026] By adopting the above technical solution, the box body is penetrated by the second guide shaft so as to slide relative to the driving assembly.

[0027] In some embodiments, the shower assembly includes a shower mount, a shower body provided on the shower mount, and a scraper provided on the shower body. The opposite ends of the shower mount are respectively connected to the slider assembly and the acceleration gear box. The shower body is provided with multiple nozzles.

[0028] By adopting the above technical solution, the shower head body and the scraper are installed on the shower head mounting seat, and the shower head body and the scraper are driven to move back and forth in a straight line on the mop, and the nozzle sprays the cleaning liquid onto the mop. At the same time, the scraper can also scrape the cleaning liquid on the mop to repeatedly clean the mop.

[0029] In some embodiments, the shower head mounting seat includes a seat body, a buckle assembly clamped on the seat body, and an adapter rotatably connected to the seat body, the adapter is connected to the output end of the active part, one end of the brush rod is fixedly connected to the adapter, and the other end is clamped with the buckle assembly.

[0030] By adopting the above technical solution, the brush rod can be detachably mounted on the shower head mounting seat. Specifically, the buckle assembly is opened relative to the seat body, one end of the brush rod is fixedly connected to the adapter, and the other end of the brush rod is installed at the opening and closing part of the buckle assembly and the seat body. The buckle assembly is then pressed relative to the seat body to fix the brush rod. Then, the torque output by the adapter drives the brush rod winding to rotate. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components.

[0064] With the improvement of living standards, more and more consumers are choosing to use machines to complete tedious housework. Among them, intelligent sweeping robots are very popular among consumers. At present, cleaning robots generally have the function of washing and mopping. Specifically, the cleaning robot can clean the floor while vacuuming.

[0065] When the mop of the cleaning robot needs to be cleaned, it needs to be returned to the cleaning base station for processing. However, the mops of current cleaning robots are mostly cleaned manually, or directly replaced with new flat mops, resulting in a poor user experience.

[0066] In view of this, an embodiment of the present application provides a cleaning base station, which is equipped with a mop cleaning mechanism. Specifically, after the cleaning robot completes its cleaning task, it enters the cleaning base station through the opening of the front shell, and the mop of the cleaning robot faces the base and is located above the shower assembly and brush rod of the mop cleaning mechanism. Then, the driving assembly of the mop cleaning mechanism drives the power active part to move relative to it, and at the same time, the sliding driven part follows the power active part to move relative to it on the guide assembly. Since the driving assembly and the guide assembly are relatively arranged, the shower assembly and the roller brush perform reciprocating linear motion on the mop. At the same time, the roller brush can also provide power for rotation around the axis through the power active part, that is, while the roller brush performs reciprocating linear motion on the mop, it also rotates around the axis. The cleaning base station provided in the embodiment of the present application can spray the mop with the shower assembly while also performing roller brush cleaning on it through the brush rod, thereby greatly improving the cleaning efficiency of the mop of the cleaning robot.

[0067] First, please refer to Figures 1 to 5 The present application provides a cleaning base station 10000 , comprising a base 200 , a front shell 300 and a mop cleaning mechanism 100 .

[0068] The front shell 300 is disposed on the base 200 , and an opening 301 is defined on the front shell 300 for the cleaning robot 400 to enter and exit.

[0069] The mop cleaning mechanism 100 includes a drive assembly 10, a guide assembly 20 disposed opposite the drive assembly 10, a connecting bracket 30 for connecting the drive assembly 10 and the guide assembly 20, and a cleaning assembly 40. The cleaning assembly 40 includes a shower assembly 43, a brush rod 44 rotatably connected to the shower assembly 43, and a power active portion 42 and a sliding driven portion 41 fixedly connected to opposite ends of the shower assembly 43. The output end of the power active portion 42 is connected to the brush rod 44. The power active portion 42 and the sliding driven portion 41 are slidably connected to the drive assembly 10 and the guide assembly 20, respectively.

[0070] The driving assembly 10 is used to drive the shower assembly 43 and the brush rod 44 to move back and forth linearly along the guide direction of the guide assembly 20 .

[0071] It can be understood that the base 200 is the main part of the cleaning base station 10000, used to support the front shell 300 and the mop cleaning mechanism 100; the front shell 300 is the outer shell part of the cleaning base station 10000, used to fix the mop cleaning mechanism 100; the mop cleaning mechanism 100 is used to clean the mop 401.

[0072] The driving assembly 10 is the main power source, used to drive the cleaning assembly 40 to perform reciprocating linear motion; the guide assembly 20 plays a corresponding guiding role to limit the reciprocating linear motion path of the cleaning assembly 40; the connecting bracket 30 serves to fix the driving assembly 10 and the guide assembly 20; the cleaning assembly 40 is mainly used to clean the surface of the mop 401.

[0073] The sliding follower portion 41 is adapted to the guide assembly 20, and the two meet the relative movement requirements, allowing the cleaning assembly 40 as a whole to move back and forth linearly between the drive assembly 10 and the guide assembly 20. The power active portion 42 is used to provide rotational power to the brush rod 44. The power active portion 42 may have a power source to directly provide rotational power to the brush rod 44, for example, the power active portion may include a motor. Alternatively, the power active portion 42 may not have a power source and provide rotational power to the brush rod 44 through a transmission method, for example, the power active portion 42 includes a gear train or other transmission components. The shower assembly 43 is used to spray cleaning fluid onto the mop 401 to clean it, while the brush rod 44 is used to roll the mop 401 to remove impurities or dirt from its surface.

[0074] Specifically, the cleaning robot 400 enters through the opening 301 and stays on the base 200 . At this time, the mop 401 of the cleaning robot 400 faces the cleaning assembly 40 of the mop cleaning mechanism 100 .

[0075] The cleaning assembly 40 of the mop cleaning mechanism 100 can perform linear reciprocating movement in a preset direction and clean the mop 401 of the cleaning robot 400 .

[0076] like Figure 3 As shown, the cleaning assembly 40 is in the front position of the mop 401 of the cleaning robot 400, and as shown Figure 4 As shown, the cleaning component 40 is in the rear position of the mop 401 of the cleaning robot 400 , and the cleaning component 40 can move back and forth linearly between the front position and the rear position to clean the mop 401 .

[0077] The cleaning base station 10000 provided in the present application enters the cleaning base station 10000 through the opening 301 of the front shell 300 after the cleaning robot 400 completes the cleaning task, and the mop 401 of the cleaning robot 400 faces the base 200 and is located above the shower assembly 43 and the brush rod 44 of the mop cleaning mechanism 100. Then, the driving assembly 10 of the mop cleaning mechanism 100 drives the power active part 42 to move relative to each other. At the same time, the sliding driven part 41 follows the power active part 42 to move relative to each other on the guide assembly 20. Since the driving assembly 10 and the guide assembly 20 are relatively arranged, the shower assembly 43 and the roller brush perform reciprocating linear motion on the mop 401. At the same time, the roller brush can also provide power for rotation around the axis through the power active part 42, that is, the roller brush performs reciprocating linear motion on the mop 401 while also rotating around the axis. The cleaning base station 10000 provided in the embodiment of the present application can spray and clean the mop 401 through the shower assembly 43, and can also clean it with a rolling brush through the brush rod 44, thereby greatly improving the cleaning efficiency of the mop 401 of the cleaning robot 400.

[0078] Please refer to Figures 4 to 8 In some embodiments, the driving assembly 10 includes a power unit 12 and a synchronous transmission unit 14 connected to an output end of the power unit 12 , and the synchronous transmission unit 14 is connected to the power active unit 42 .

[0079] It can be understood that the power unit 12 is a mechanism that can directly output torsion, such as a motor, a telescopic cylinder, hydraulic pressure, etc.

[0080] The synchronous transmission unit 14 is used to convert the torque of the power unit 12 into a reciprocating linear driving force, which is transmitted to the active power unit 42 to drive the active power unit 42 to reciprocate linearly. For example, the synchronous transmission unit 14 can be a synchronous transmission belt mechanism, that is, a synchronous belt structure is wrapped around two pulleys, which drives the synchronous belt to circulate and reciprocate. Alternatively, the synchronous transmission unit 14 can be a screw mechanism, in which the screw body rotates around the axis, driving the nut structure to reciprocate in the axial direction of the screw body.

[0081] In this way, the power unit 12 is used to provide a power source. For example, the power unit 12 can be a motor, a telescopic cylinder, a hydraulic cylinder, etc., and the synchronous transmission unit 14 is used to transmit torque to the power active unit 42, thereby driving the power active unit 42 to move back and forth linearly.

[0082] Please refer to Figures 4 to 8In some embodiments, the power unit 12 includes a driving motor, and the synchronous transmission unit 14 includes a first pulley 143 connected to the output end of the driving motor, a second pulley 144 spaced apart from the first pulley 143, and a synchronous belt 145 wound around the first pulley 143 and the second pulley 144, and the synchronous belt 145 is connected to the power active unit 42.

[0083] It can be understood that the output end of the drive motor transmits the torque to the first pulley 143, driving the first pulley 143 to rotate around the axis, and the first pulley 143 drives the synchronous belt 145 to move back and forth, and the second pulley 144 plays a corresponding role in assisting and supporting the synchronous belt 145.

[0084] In this way, the driving motor provides a power source and outputs torque to the first pulley 143 to drive the first pulley 143 to rotate. The first pulley drives the second pulley 144 to rotate through the synchronous belt 145. In this way, the synchronous belt 145 transmits the power back and forth between the first pulley 143 and the second pulley 144, and finally drives the power active part 42 to perform reciprocating linear motion.

[0085] Please refer to Figures 4 to 8 In some embodiments, the drive assembly 10 further includes a drive housing 11 and two collision switches 113 disposed in the drive housing 11 and configured to contact and collide with the power active portion 42 . Each collision switch 113 is electrically connected to the drive motor, wherein one collision switch 113 is disposed close to the first pulley 143 , and the other collision switch 113 is disposed close to the second pulley 144 .

[0086] It can be understood that the two collision switches 113 should be connected in parallel with the drive motor, that is, when the power active part 42 moves to the vicinity of the first pulley 143 and triggers the collision switch 113 there, the drive motor reverses and rotates, so that the synchronous belt 145 is transmitted in the opposite direction. At this time, the power active part 42 is driven to move toward the second pulley 144; until the power active part 42 moves to the vicinity of the second pulley 144 and triggers the collision switch 113 there, the drive motor reverses and rotates, so that the synchronous belt 145 is transmitted in the opposite direction. At this time, the power active part 42 is driven to move toward the first pulley 143, and thus circulates back and forth between the two pulleys.

[0087] Thus, when the power active part 42 moves back and forth linearly, it can touch the corresponding collision switch 113 when it moves to the two extreme positions, so as to adjust the direction of the driving motor through the relative collision switch 113, so that the power active part 42 can move back and forth linearly.

[0088] Alternatively, as Figures 4 to 8As shown, the drive assembly 10 also includes a reduction gear set 13, the drive housing 11 has a first side surface 11a and a second side surface 11b arranged opposite to each other, the drive motor is arranged on the first side surface 11a, the reduction gear set 13 is arranged on the second side surface 11b, and the synchronous transmission part 14 also includes a first synchronous wheel 141 arranged on the first side surface 11a and rotating coaxially with the last gear of the reduction gear set 13, and a second synchronous wheel 142 that drives the first synchronous wheel 141, wherein the first pulley 143 is arranged on the second side surface 11b and rotates coaxially with the second synchronous wheel 142.

[0089] The first side surface 11a and the second side surface 11b are two side walls of the drive housing 11 that are arranged opposite to each other, one of which faces the guide assembly 20, and the other faces away from the guide assembly 20. The power unit 12, the reduction gear set 13, and the synchronous transmission unit 14 are arranged on different sides of the drive housing 11, which makes the layout more compact, and can make the overall volume of the drive assembly 10 smaller and the space occupied smaller.

[0090] At the same time, the driving motor is arranged on the first side 11a, and its input end should pass through the driving housing 11 to the second side 11b, so that it is meshed with the first gear of the reduction gear set 13 located on the second side 11b; and the last gear of the reduction gear set 13 rotates on the same axis as the first synchronous gear 141, and the first synchronous gear 141 then drives the second synchronous gear 142 to rotate around the axis, and then rotates on the same axis as the first pulley 143 through the second synchronous gear 142, then the output torque of the driving motor is transferred from the first side 11a to the second side 11b, and finally, the synchronous belt 145 circulates back and forth between the first pulley 143 and the second pulley 144.

[0091] Optionally, the synchronous transmission unit 14 further includes a tensioning wheel, which is used to adjust the tension of the synchronous belt 145 to improve the transmission efficiency of the synchronous belt 145.

[0092] In this way, the reduction gear set 13 and the synchronous transmission part 14 are arranged on the first side surface 11a and the second side surface 11b of the driving housing 11 as needed, which can reduce the overall volume of the driving assembly 10 to a certain extent.

[0093] Please refer to Figure 19 In some embodiments, the guide assembly 20 includes a guide shell 21 connected to the connecting bracket 30 and a first guide shaft 211 disposed in the guide shell 21. A first through hole 411 is provided on the sliding follower 41 for the first guide shaft 211 to pass through, so that the sliding follower 41 is slidably connected to the first guide shaft 211.

[0094] It can be understood that the guide housing 21 is the main body of the guide assembly 20 and is also the part connected to the connecting bracket 30. The first guide shaft 211 is adapted to adapt to the sliding follower 41 to guide the sliding follower 41. Here, the layout and extension direction of the first guide shaft 211 determine the reciprocating linear movement direction of the sliding follower 41.

[0095] The sliding follower 41 is sleeved on the first guide shaft 211 through the first through hole 411 , and the corresponding guiding requirements are met by utilizing the hole-shaft matching relationship.

[0096] Optionally, a linear bearing is provided in the first through hole 411 to improve the smoothness of the relative movement between the sliding driven part 41 and the first guide shaft 211 .

[0097] In this way, the sliding follower 41 is inserted into the first guide shaft 211 to slide relative to the guide assembly 20 .

[0098] In some embodiments, the power active part 42 includes a box body 421 and a power source disposed on the box body 421 , and an output end of the power source is connected to the brush rod 44 .

[0099] It can be understood that in this embodiment, the power active part 42 has an independent power source, that is, the rotation speed and rotation direction of the brush rod 44 around the axis are determined by the output torque of the power source.

[0100] Here, the power source includes but is not limited to a servo motor, a stepper motor, and the like.

[0101] In this way, the power source can be various types of motors, which can directly or indirectly output torque to the brush rod 44 to drive the brush rod 44 to rotate around the axis, that is, the rotation around the axis of the brush rod 44 and the reciprocating linear movement of the brush rod 44 are independent of each other and do not interfere with each other.

[0103] It can be understood that in this embodiment, the power active part 42 does not have an independent power source. When the box body 421 moves relative to the driving assembly 10, the first gear of the acceleration gear set 422 is meshed and connected with the rack 112 to obtain the output torque, and through a series of gear transmissions in the acceleration gear set 422, the torque is finally transmitted from the last gear of the acceleration gear set 422 to the brush rod 44.

[0104] Here, the rotation speed and direction of the brush rod 44 around the axis are determined by the movement rate of the box 421 relative to the drive assembly 10 , and are also determined by the magnitude and direction of the output torque of the output end of the drive assembly 10 .

[0105] like Figure 20 As shown, when the cleaning assembly 40 moves from the front position of the mop 401 of the cleaning robot 400 to the rear position, the brush rod 44 rotates clockwise; Figure 21 As shown, when the cleaning assembly 40 moves from the rear position of the mop 401 of the cleaning robot 400 to the front position, the brush rod 44 rotates counterclockwise.

[0106] In this way, when the box body 421 and the acceleration gear set 422 move back and forth linearly relative to the driving assembly 10, the first gear of the acceleration gear set 422 is engaged with the rack 112, and the last gear of the acceleration gear set 422 provides rotational torque for the brush rod 44, that is, the reciprocating linear movement rate of the brush rod 44 affects the rotation rate of the brush rod 44 around the axis. Specifically, the faster the reciprocating linear movement rate of the brush rod 44, the faster the rotation rate of the brush rod 44 around the axis.
