Abstract

The utility model provides a base station. In the base station, under the combined action of the driving assembly and the reset assembly, the scheme that the clamping piece can stretch out and draw back relative to the machine shell of the base station is achieved through the sliding piece; therefore, the clamping part of the clamping piece can be in an extending state in which the clamping part is clamped with a wet type cleaning assembly of self-moving cleaning equipment and a retracting state in which the clamping part is released from the wet type cleaning assembly in an automatic mode without manual operation; therefore, automatic disassembly and assembly of the wet-type cleaning assembly can be achieved while the wet-type cleaning assembly and the main machine of the self-moving cleaning equipment are connected and separated in a controlled mode. Therefore, the problems that operation is tedious and an operator is prone to being stained due to manual disassembly and assembly of the wet type cleaning assembly are solved.

Description

Technical Field

[0001] The present disclosure relates to an engaging / disengaging mechanism between a base station and a self - moving cleaning device, and more particularly to a base station including an automatic disassembly and assembly mechanism for a wet cleaning assembly of a self - moving cleaning device. Background Art

[0002] An autonomous mobile device refers to an intelligent mobile device that autonomously performs preset tasks and can autonomously move on a traveling surface according to the results sensed by its sensing components. Currently, autonomous mobile devices generally include, but are not limited to, self - moving cleaning devices (such as intelligent floor sweepers, intelligent floor scrubbers, window cleaning robots), companion mobile robots (such as intelligent electronic pets, nanny robots), service - type mobile robots (such as reception robots in hotels, inns, meeting places), industrial inspection intelligent devices (such as power inspection robots, intelligent forklifts, etc.), and security robots (such as household or commercial intelligent guard robots).

[0003] For existing self - moving cleaning devices with wet cleaning components, in some application scenarios, it is necessary to disassemble the wet cleaning components, which is usually manually completed by the operator, resulting in problems such as cumbersome operation and the operator being easily soiled.

[0011] A driving assembly is installed on the housing and cooperates with the sliding member to overcome the action force to drive the sliding member, thereby driving the at least one clamping portion to be in the retracted state.

[0012] In an optional solution, the reset assembly includes at least one coil spring, and the coil spring applies a spring force as an acting force to the sliding member and / or the clamping member.

[0013] In another optional solution, the sliding member includes a base portion and a guide portion fixed to each other, the base portion is supported by the housing, and the guide portion is arranged on the base portion and is formed with a guide surface for guiding the extension and retraction of the clip.

[0014] The guide surface is formed in a step shape and includes a first plane section, a transition section, and a second plane section. The first plane section is located above the second plane section. The transition section extends obliquely downward from the first plane section to the second plane section.

[0015] In another optional solution, one of the base portion and the housing is provided with a base guide groove, and the other of the base portion and the housing is provided with a guide protrusion, and the base guide groove cooperates with the guide protrusion to guide the sliding member to perform reciprocating linear motion relative to the housing.

[0016] In another optional solution, the sliding member includes a plurality of the guide portions.

[0017] The clamping member also includes a main body and a plurality of guided parts, wherein at least one clamping part is fixedly arranged on the main body, and the plurality of guided parts are fixedly arranged on the main body, and each of the guided parts is guided by a guiding surface of the corresponding guiding part, so that the main body can move while the plurality of guided parts are guided at the same time.

[0018] In another optional scheme, the driving assembly includes a motor and a gear rack assembly, the gear rack assembly includes an output gear and a rack that mesh with each other, the output gear is transmission-connected to the motor, and the rack is mounted on the housing, so that the motor is used to drive the output gear to rotate so that the assembly of the motor and the output gear can realize the reciprocating motion on the rack.

[0019] In another optional solution, the driving assembly further includes a multi-stage gear pair, the motor is transmission-connected to the output gear via the multi-stage gear pair, and the multi-stage gear pair can perform the reciprocating motion along with the assembly.

[0020] In another alternative solution, the housing is formed with a cleaning groove, and the driving assembly further includes two tracks which are respectively arranged on two opposite side walls of the cleaning groove. The rack is fixedly arranged on the corresponding track and extends along the same direction as the extending direction of the track.

Thus, it is not necessary to manually make the clamping portion of the clamping member be in an extended state engaged with, for example, a wet cleaning assembly of a self-moving cleaning device and a retracted state disengaged from the wet cleaning assembly in an automatic manner, so that the wet cleaning assembly can be automatically disassembled and assembled while the wet cleaning assembly is controllably engaged with and separated from the main body of the self-moving cleaning device. This will avoid problems such as cumbersome operation caused by manually disassembling and assembling the wet cleaning assembly and the operator being easily soiled. Description of the Drawings

[0042] The embodiments of the present disclosure will be described below with reference to the accompanying drawings. For ease of understanding, the elements shown in the respective drawings may include elements represented differently from the actual dimensions and scales, such as dimensions and scales.

[0043] The base station according to the embodiments of the present disclosure will be described below in conjunction with the accompanying drawings of the specification.

[0044] As Figures 1 to 7 shown, the base station according to the embodiments of the present disclosure includes a housing 1, a sliding member 2, a clamping member 3, a reset assembly (including a helical spring 4), a driving assembly 5, a sensing assembly 6, a first cleaning brush 7, and a second cleaning brush 8 assembled together.

[0045] In this embodiment, as Figure 1 shown, the housing 1 is used to support and protect other components. The structure and shape of the housing 1 are not limited to any specific structure and shape, but any desired structure and shape can be adopted as long as the above functions can be achieved. In addition to an installation space for accommodating other components that can be formed inside the housing 1, the housing 1 also forms a storage cavity for a self - moving cleaning device to dock. A cleaning groove 1c can be formed at the bottom of the storage cavity. The cleaning groove 1c has an opening facing upward for collecting the waste liquid of a wet cleaning member, such as a rag or a mop, for cleaning the self - moving cleaning device. In addition, referring to Figure 8 and Figure 9 , the housing 1 also forms a through - hole 1h for the clamping portion 31 of the clamping member 3 to protrude. When the clamping portion 31 of the clamping member 3 is in the protruding state, the clamping portion 31 partially protrudes from the housing 1 via the through - hole 1h; when the clamping portion 31 of the clamping member 3 is in the retracted state, the clamping portion 31 completely retracts into the housing 1 via the through - hole 1h.

[0046] In this embodiment, the sliding member 2 is installed inside the housing 1 and can reciprocate linearly relative to the housing 1. As Figure 2 and Figure 3 shown, the sliding member 2 includes a base portion 21 and a guiding portion 22 fixed to each other by integral molding.

[0047] As Figure 2 and Figure 3As shown, the entire base portion 21 is formed in a long strip shape that extends linearly along the width direction of the base station and is supported by the housing 1. One end portion of the base portion 21 is formed with a driven portion 211 for being directly driven by the driving assembly 5, and the driven portion 211 is formed in a flat plate structure that protrudes downward. The base portion 21 is also formed with a plurality of base guide grooves 21c that are spaced apart in its length direction, and each base guide groove 21c opens upward. The housing 1 is provided with guide protrusions 11 that are inserted into each base guide groove 21c. On the one hand, the guide protrusions 11 cooperate with the base guide grooves 21c to smoothly guide the reciprocating linear motion of the sliding member 2 and the housing 1, preventing the sliding member 2 from being skewed during the movement; on the other hand, the guide protrusions 11 cooperate with the base guide grooves 21c to also limit the movement range of the sliding member 2 while the sliding member 2 is installed on the housing 1, preventing the sliding member 2 from moving excessively.

[0048] It can be understood that the base portion 21 is not limited to the specific structure described above. As long as the base portion 21 can be driven by the driving assembly 5 to generate reciprocating motion, the base portion 21 can adopt any desired shape and structure. In addition, as long as the reciprocating motion of the base portion 21 can be guided, the base guide grooves 21c can be provided in either the base portion 21 or the housing 1, and the guide protrusions 11 can be provided in the other of the base portion 21 and the housing 1.

[0049] As Figure 3 shown, two guide portions 22 are arranged side by side on the side portion of the base portion 21 at intervals in the length direction of the base portion 21. Each guide portion 22 is formed with a guide surface 22s for guiding the engaging member 3, so that the engaging member 3 expands and contracts relative to the housing 1 during the reciprocating motion of the sliding member 2 by means of the guide surface 22s and the guided portion 33 that cooperates with it. Specifically, the guide surface 22s is formed in a stepped shape and includes a first flat section 22s1, a transition section 22s2, and a second flat section 22s3 that are connected to each other. The first flat section 22s1 and the second flat section 22s3 extend along the length direction of the base portion 21, the first flat section 22s1 is located above the second flat section 22s3, and the transition section 22s2 extends obliquely downward from the first flat section 22s1 to the second flat section 22s3. Thus, the engaging member 3 is extended relative to the housing 1 by means of the upper first flat section 22s1, so that the engaging portion 31 is in an extended state; the engaging member 3 is retracted relative to the housing 1 by means of the lower second flat section 22s3, so that the engaging portion 31 is in a retracted state. The structure of this alternative solution is simple, operates reliably, and is easy to implement.

[0050] It can be understood that the number of the guide portions 22 can be adjusted as needed, and then the guided portions 33 of the engaging members 3 are provided corresponding to the guide portions 22 one by one.

[0051] In this embodiment, as Figure 1 shown, the snap - fitting member 3 is installed on the housing 1 and most of the structure of the snap - fitting member 3 is located inside the housing 1. As Figure 2 and Figure 3 shown, the snap - fitting member 3 includes two snap - fitting portions 31, a body portion 32, and two guided portions 33 that are fixed to each other by integral molding. The two snap - fitting portions 31 are provided at the upper end of the body portion 32 and are formed in a hook shape. The two snap - fitting portions 31 can be in a protruding state and a retracted state relative to the housing 1 with the reciprocating movement of the sliding member 2. Thus, the snap - fitting portions 31 can be snap - fitted with and disengaged from the wet cleaning assembly of the self - moving cleaning device. The two guided portions 33 are located at the lower end of the body portion 32 and are formed in a cylindrical shape protruding from the body portion 32. The two guided portions 33 can be guided by the guiding surfaces 22s of the corresponding guiding portions 22, so that the body portion 32 moves when the two guided portions 33 are simultaneously guided. The multiple guiding portions 22 can respectively guide the guided portions 33 simultaneously, so that the body portion 32 can be reliably driven to move, reducing the risk of being stuck and skewed during the movement.

[0052] In this embodiment, as Figure 2 shown, the reset assembly includes a helical spring 4. One end of the helical spring 4 is installed on the sliding member 2 and the other end is installed on the housing 1. Once the sliding member 2 is driven by the driving assembly 5 to leave the initial position (where the snap - fitting portion 31 is in the protruding state), the helical spring 4 can apply a spring force to the sliding member 2, and under the direct action of this spring force, the sliding member 2 tends to return to the initial position. In addition, the reset assembly can also include an additional spring (not shown in the figure), and the additional spring can directly act on the snap - fitting portion 31 to apply a spring force to keep it in the protruding state. The spring force of the additional spring can also make the guided portion 33 of the snap - fitting member 3 always abut against the guiding surface 22s of the guiding portion 22, thus ensuring that the guiding surface 22s more smoothly guides the snap - fitting portion 31 to expand and contract.

[0053] It can be understood that as long as the reset assembly can apply a force that makes the snap - fitting portion 31 tend to maintain the protruding state, the reset assembly can use springs with any number and various installation positions. For example, the reset assembly can include multiple springs that apply forces to the sliding member 2 and / or the snap - fitting member 3 to achieve the above effects.

[0054] In this embodiment, the driving assembly 5 is installed on the housing 1 and cooperates with the sliding member 2 to drive the sliding member 2 by overcoming the acting force, and then drive the snap - fitting portion 31 to be in the retracted state. As Figures 4 to 6 shown, the driving assembly 5 includes a motor 51, a gear - rack assembly, a multi - stage gear pair, a track 54, and a guide wheel 55.

[0055] AsFigure 4 and Figure 6 As shown, the motor 51, the output gear 52 of the rack and pinion assembly, the multi-stage gear pair, and the guide wheel 55 can reciprocate linearly on the cleaning groove 1c of the housing 1 as an assembled body. The motor 51 has a motor shaft for outputting torque. The motor shaft is drivingly connected to the output gear 52 via the multi-stage gear pair, so as to increase the torque output by the motor 51 and then transmit it to the output gear 52. The rack and pinion assembly includes an output gear 52 and a rack 53 that mesh with each other. The rack 53 is installed on the housing 1, so that the motor 51 drives the output gear 52 to rotate, thereby enabling the above-mentioned assembled body to perform a reciprocating linear motion on the rack 53. The reciprocating linear motion of the drive assembly 5 is realized by driving the rack and pinion assembly by the motor 51. Compared with a mechanism that uses, for example, a belt drive method, the rack and pinion assembly can save occupied space and can realize a reciprocating linear motion in a stable and reliable manner. In addition, the gear transmission mechanism composed of the multi-stage gear pair can increase the torque from the motor 51, so that the slider 2 has sufficient power to move. Further, as Figure 5 shown, two tracks 54 are respectively arranged on the opposite side walls of the cleaning groove 1c and linearly extend along the width direction of the base station. The rack 53 is fixedly arranged on the corresponding track 54 and extends along the same direction as the extension direction of the track 54. The guide wheel 55 is located in the track 54 and can roll in the track 54. By the guidance of the track 54 and the guide wheel 55 and the transmission of the output gear 52 and the rack 53, the drive assembly 5 including the above-mentioned assembled body can smoothly perform a reciprocating linear motion on the cleaning groove 1c. Further, during the reciprocating linear motion of the above-mentioned assembled body, it can be controlled to abut against the driven portion 211 of the base portion 21 of the slider 2, thereby pushing the entire slider 2 to move in one direction. During this process, the guide surface 22s of the guide portion 22 of the slider 2 guides the engaged portion 31 of the engaging member 3 to retract relative to the housing 1 via the guided portion 33 of the engaging member 3. Once the above-mentioned assembled body moves in a direction away from the driven portion 211, the reset assembly will cause the entire slider 2 to move in another direction opposite to the above-mentioned one direction. During this process, the guide surface 22s of the guide portion 22 of the slider 2 guides the engaged portion 31 of the engaging member 3 to extend relative to the housing 1 via the guided portion 33 of the engaging member 3.

[0056] In this embodiment, as Figure 5 and Figure 7As shown, the sensing component 6 includes an infrared sensor 61 and an encoder 62 that cooperates with the infrared sensor 61. The infrared sensor 61 is disposed on the housing 1, and the encoder 62 is disposed on the above-mentioned assembly. The position of the assembly can be sensed by using an infrared sensor 61 and an encoder 62. When the sensed data is transmitted to the control unit of the base station, the reciprocating linear motion of the driving component 5 can be controlled accordingly. Since only one infrared sensor 61 is adopted, the related structure can be simplified and the cost can be saved compared with the prior art solutions that adopt multiple sensors with similar functions.

[0057] It can be understood that the setting manners of the infrared sensor 61 and the encoder 62 are not limited to the above-described solutions. As long as one of the infrared sensor 61 and the encoder 62 is disposed on the housing 1, and the other of the infrared sensor 61 and the encoder 62 is disposed on the assembly.

[0058] In this embodiment, as Figure 5 shown, the first cleaning brush 7 and the second cleaning brush 8 are installed on the above-mentioned assembly. The first cleaning brush 7 can be a brush with a large number of bristles and is located at the top of the above-mentioned assembly. The first cleaning brush 7 that reciprocates linearly with the above-mentioned assembly can effectively clean a wet cleaning member such as a rag of the wet cleaning component parked at the base station. The second cleaning brush 8 can be a rubber wiper and is located at the bottom of the above-mentioned assembly. The second cleaning brush 8 is always in contact with the bottom surface of the cleaning tank 1c. The second cleaning brush 8 that reciprocates with the above-mentioned assembly can collect the sewage that falls from the wet cleaning member into the cleaning tank 1c to one side of the cleaning tank 1c for discharge. In addition, the bottom surface of the cleaning tank 1c is configured to have a surface with concave and convex textures. The concave texture here can be formed by a fine concave and convex array or a texture such as a three-dimensional leather pattern. Since the bottom surface of the cleaning tank 1c is formed to have a surface with concave and convex textures, the related noise generated during the movement in the state where the second cleaning brush 8 is in contact with the bottom surface can be reduced.

[0059] By adopting the above solution, when the two clamping portions 31 of the clamping member 3 are in the extended state relative to the housing 1 (as Figure 9 shown), each clamping portion 31 extends out of the housing 1 through the corresponding through hole 1h. When the two clamping portions 31 of the clamping member 3 are in the retracted state relative to the housing 1 (as Figure 8As shown, each engaging portion 31 retracts from the corresponding through hole 1h such that the engaging portion 31 does not protrude outside the housing 1. In this way, under the combined action of the driving assembly 5 and the reset assembly, the engaging portion 31 can be in an extended state engaged with, for example, a wet cleaning assembly of a self - moving cleaning device and a retracted state disengaged from the wet cleaning assembly. The state transition of the engaging portion 31 is automatically achieved by the mechanism including the driving assembly 5 and the sliding member 2 as described above, so that the automatic disassembly of the wet cleaning assembly to the base station and the reassembly to the self - moving cleaning device can be realized.

[0060] The structure of the self - moving cleaning device used in conjunction with the above - mentioned base station will be described below.

[0061] In the present disclosure, the self - moving cleaning device has a main body. The main body has an overall circular shape in a top view. In other variant examples, the main body can have various shapes such as a D - shaped, oval, etc. When the self - moving cleaning device is in a normal operating state, the bottom surface of the main body faces the surface to be cleaned, and the bottom surface of the main body is usually parallel to the surface to be cleaned. Here, "parallel" includes not only the geometric parallel relationship between the bottom surface of the main body and the surface to be cleaned, but also the case where the two are approximately parallel. The above "approximately" means that within the reasonable error range recognized by those skilled in the art, the parallel relationship between the two can be determined to be established. In addition, for supporting and protecting other components, other components of the self - moving cleaning device are usually installed inside the main body or have a connection relationship with the main body.

[0062] The self - moving cleaning device can move autonomously according to a preset control scheme in its processing unit. The surface to be cleaned where the self - moving cleaning device moves autonomously can be a flat surface or a curved surface with a relatively large radius of curvature. Typically, for example, it is the floor in each room of a building. The processing unit in this disclosure is a general term, and there are no restrictions on the type, quantity, and form of the processing unit. Specifically, the processing unit can be one or several of MCU, DSP, FPGA, GPU, or it can also be other various hardware chips, processors, or software algorithms with data processing and computing capabilities. Further, the processing unit can be the unified and unique processor of the self - moving cleaning device, or it can be a collection of multiple processing units. The connection method, functions, and computing power distribution of multiple processing units can be adjusted as needed. For example, in an alternative solution, it can include a first processing unit and a second processing unit. In this case, the first processing unit and the second processing unit together implement various functions of the above - mentioned processing unit. In addition, the processing unit of the self - moving cleaning device according to this disclosure can receive parameters from the sensing unit and can control the self - moving cleaning device through a preset program stored in the storage unit. In this disclosure, the data, information, and programs required by the processing unit during the processing can be stored in the storage unit and retrieved from the storage unit as needed. The processing unit can store the processed data, information, etc. in the storage unit again. The storage unit can be RAM, ROM, etc., or it can also be devices and / or equipment with storage functions such as cloud / servers / mobile terminals connected through wired / wireless networks.

[0063] In addition, in order to implement the autonomous movement of the self - moving cleaning device, the self - moving cleaning device according to the present disclosure may further include a wheel assembly. The wheel assembly can be mounted on the main body and protrude relative to the bottom surface of the main body, and is used to drive the entire self - moving cleaning device to travel on the surface to be cleaned under the control of the processing unit. By rotating the wheels (drive wheels) of the two wheel assemblies at the same speed in the same direction (for example, rotating clockwise simultaneously or counter - rotating counter - clockwise simultaneously), the self - moving cleaning device can be driven to move in a straight line along the forward movement direction; by rotating the drive wheels of the two wheel assemblies at different speeds and / or in different directions (for example, one drive wheel rotates clockwise while the other drive wheel rotates counter - clockwise), the self - moving cleaning device can be driven to perform a steering movement along a direction different from the forward movement direction. The self - moving cleaning device may further include a caster wheel disposed on the main body, so that the caster wheel can support the entire self - moving cleaning device regardless of how the drive wheels roll on the surface to be cleaned. In addition, the self - moving cleaning device includes a wet cleaning assembly and a dry cleaning assembly. The wet cleaning assembly is disposed on the main body and includes a bracket and wet cleaning parts such as a mop and a rag, etc., and the dry cleaning assembly is disposed on the main body and may include a main brush, a side brush (edge brush), and a suction device, etc. Thus, when the self - moving cleaning device travels on the surface to be cleaned, the surface to be cleaned can be cleaned through the dry cleaning assembly and / or the wet cleaning assembly. In different working modes, the cleaning operations achieved by the self - moving cleaning device include, but are not limited to, one or more of operations such as sweeping the floor, mopping the floor, and vacuuming.

[0064] See the following Figure 8 and Figure 9 to illustrate the working process of the above - mentioned base station.

[0065] In a state where the base station is installed in place, the clamping member 3 can be applied with a force by the reset assembly, so that the clamping portion 31 of the clamping member 3 protrudes relative to the housing 1, and then the clamping portion 31 partially protrudes through the through - hole 1h of the housing 1. Further, after the self - moving cleaning device is guided to dock with the base station, the clamped portion of the wet cleaning assembly of the self - moving cleaning device will be clamped with the clamping portion 31 of the above - mentioned clamping member 3. In this state, once the main body and the wet cleaning assembly of the self - moving cleaning device are disassembled, the wet cleaning assembly can be automatically disassembled to the base station.

[0066] When the wet cleaning component of the self - moving cleaning device needs to be assembled to the main body, the control unit of the base station controls the motor 51 to rotate, driving the assembly including the motor 51 to move. The assembly can abut against the driven part 211 of the sliding member 2, and then move the driven part 211 while overcoming the acting force of the reset component. The guiding surface 22s of the guiding part 22 of the sliding member 2 guides the guided part 33 of the engaging member 3, so that the engaging part 31 of the engaging member 3 retracts relative to the housing 1 through the through - hole 1h. At this time, the engaging part 31 of the engaging member 3 disengages from the engaged part of the wet cleaning component. In this state, once the main body of the self - moving cleaning device and the wet cleaning device return to the assembled state, the wet cleaning component can be automatically assembled with the main body of the self - moving cleaning device.

[0067] In this way, under the combined action of the driving component 5 and the reset component, a solution is realized in which the engaging member 3 can expand and contract relative to the housing 1 of the base station via the sliding member 2. Thus, without manual operation, the engaging part 31 of the engaging member 3 can be automatically in the extended state of engaging with, for example, the wet cleaning component of the self - moving cleaning device and the retracted state of disengaging from the wet cleaning component. Therefore, while the wet cleaning component is controllably engaged and separated from the main body of the self - moving cleaning device, automatic disassembly and assembly of the wet cleaning component can be achieved. This will avoid problems such as cumbersome operation caused by manual disassembly and assembly of the wet cleaning component and the operator being easily soiled.

[0068] It should be understood that the above - mentioned embodiments are merely exemplary and not intended to limit the present disclosure. Those skilled in the art can make various modifications and changes to the above - mentioned embodiments under the teaching of the present disclosure without departing from the scope of the present disclosure. The following supplementary explanations are made for the technical solutions of the present disclosure.
