[0049] AsFigures 1 to 13 The embodiment of the utility model provides a kind of clamping assembly 100, mobile device and cleaning system as shown in the figure.The clamping assembly 100 is applied to mobile device, and mobile device can be self-moving cleaning device, and self-moving cleaning device can be understood as the device that can move and clean by itself, such as self-moving cleaning device can be floor cleaning robot, sweep and mop integrated machine, mop robot etc.It can be understood that mobile device can also be automatic food delivery robot, express sorting robot etc.Concretely, for the convenience of description, the technical scheme of the present disclosure is described by taking self-moving cleaning device as an example.

[0050] Specifically, self-moving cleaning device includes but is not limited to: device body, cleaning system, drive system etc.The above-mentioned various systems are coordinated with each other, so that self-moving cleaning device can move autonomously to realize cleaning function.Functional elements etc.

[0051] As shown in Figure 2 , Figure 10 and Figure 11 The utility model provides mobile device including mechanical arm 210, wherein, mechanical arm 210 can be connected to device main body, and mechanical arm 210 can realize the grabbing or moving of obstacle, article, rubbish in the vicinity of mobile device, to better realize autonomous cleaning function.Further, mobile device can also include the mechanical arm of connecting mechanical arm 210 and device main body, and the relative position of mechanical arm 210 and device main body can be adjusted through mechanical arm, so that mechanical arm 210 can be more accurate, flexible, conveniently grab or move obstacle, article, rubbish in the vicinity of mobile device, simultaneously, the setting of mechanical arm can increase the movement range of mechanical arm 210 relative to device main body, to further improve the cleaning range of mobile device, expand the use range of product.Concretely, mechanical arm can realize the height adjustment of mechanical arm 210 relative to device main body X, Y, Z direction, wherein, Z direction can be vertical direction, and the plane of XY can be horizontal plane.

[0052] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 9As shown, the embodiment of the first aspect of the utility model provides a kind of clamping assembly 100, clamping assembly 100 includes: connecting seat 110, connecting seat 110 is formed with and / or is installed with fixed structure 120, fixed structure 120 is configured as the clamping piece 400 to be detachably connected, connecting seat 110 is further provided with clamping part 111, manipulator 210 is configured as clamping or releasing clamping part 111.

[0053] Wherein, the clamping piece 400 can be understood as the object that cannot be directly grabbed by manipulator 210 or the object that there is the possibility of falling after being grabbed.For example, the clamping piece 400 can be cylindrical, curved surface and so on, the clamping piece 400 of cylindrical and curved surface is not convenient for manipulator 210 to successfully grab due to the relatively smooth outer surface, or there is the problem of falling after being grabbed by manipulator 210 due to skidding.Specifically, the clamping piece 400 can be cat toy, such as cylindrical cat toy.

[0054] In the embodiment, clamping assembly 100 includes connecting seat 110, the clamping piece 400 can be fixed on connecting seat 110 by fixed structure 120 on connecting seat 110, and manipulator 210 on mobile device can clamp connecting seat 110 by clamping part 111 on connecting seat 110, to indirectly fix connecting seat 110 on device main body, and then indirectly fix the clamping piece 400 on device main body, so that mobile device moves, can drive the clamping piece 400 fixed on connecting seat 110 to move synchronously, so that the clamping piece 400 can move with device main body moves.Therefore, the problem that the clamping piece 400 cannot be successfully grabbed by manipulator 210 or is easy to fall after being grabbed due to special shape in the related art is solved, the shape and range of movable article that can be grabbed by mobile device are increased, the use range of mobile device is improved, and the use experience of user is improved.

[0055] Specifically, the to-be-clamped member 400 can be a cylindrical cat teaser. Since the cylindrical cat teaser is long and thin and the outer surface is smooth, the manipulator 210 cannot directly and firmly grasp the cat teaser. In this embodiment, the cat teaser is firmly and reliably fixed on the connecting seat 110 through the fixing structure 120 by cooperation of the clamping assembly 100 and the manipulator, and the connecting seat 110 is clamped by the manipulator 210 through the clamping portion 111. Thus, the cat teaser can be indirectly fixed on the device main body, so that the movement of the device main body of the mobile device can drive the cat teaser to move synchronously, so that the mobile device can play the function of teasing the cat, and the functional diversification of the mobile device is realized. For example, when the mobile device is a self-moving cleaning device, the mobile device can perform cleaning operation and cat teasing operation, and the functional diversification improves the user experience. Specifically, the cat teasing operation can be performed by cooperation of the manipulator 210 and the clamping assembly 100 while the mobile device performs the cleaning operation, so that the mobile device can simultaneously perform the cleaning operation and the cat teasing operation, the functional diversification is realized, and the energy consumption is saved. It can be understood that the cleaning operation and the cat teasing operation can also be performed separately.

[0056] It can be understood that when the cat teasing operation is not needed, the manipulator 210 can release the clamping portion 111, that is, the manipulator 210 can be separated from the connecting seat 110, so as to realize the separation of the clamping assembly 100 and the manipulator 210, and then realize the separation of the to-be-clamped member 400 and the device main body. At this time, the mobile device is still an independent device, the structure of the mobile device is not changed, the volume of the mobile device is not changed, and the original function of the mobile device can still be realized.

[0057] Further, the fixing structure 120 is configured to detachably connect the to-be-clamped member 400, so that the to-be-clamped member 400 is detachably connected with the connecting seat 110 through the fixing structure 120. Thus, the same clamping assembly 100 can be applied to different to-be-clamped members 400, and the use range of the clamping assembly 100 is improved. At the same time, the to-be-clamped member 400 and the clamping assembly 100 can be conveniently disassembled and assembled, so that the to-be-clamped member 400 and the clamping assembly 100 can be individually maintained and stored.

[0058] That is, the clamping assembly 100 provided by the embodiment can fix the to-be-clamped part 400 through the fixing structure 120 of the connecting seat 110, and the clamping part 111 shaped according to the mechanical arm 210 is arranged on the connecting seat 110, so that the mechanical arm 210 can smoothly clamp or release the connecting seat 110 through the clamping part 111, and therefore, the connecting seat 110 can be selectively clamped or released by the mechanical arm 210 according to whether the mobile device needs to clamp the to-be-clamped part 400 for cat teasing and other auxiliary operations, so as to indirectly connect or release the device main body and the to-be-clamped part 400, thereby meeting the requirement of the mobile device for releasing cat teasing and other auxiliary operations, increasing the function of the mobile device, and improving the satisfaction of users.

[0059] The clamping part 111 is shaped according to the mechanical arm 210, that is, the shape of the clamping part 111 matches the shape of the mechanical arm 210, so that the accuracy, convenience and stability of the mechanical arm 210 clamping the connecting seat 110 through the clamping part 111 are improved, and the to-be-clamped part 400 can be stably, reliably and indirectly fixed on the device main body through the connecting seat 110 and the mechanical arm 210.

[0060] The fixing structure 120 can be formed on the connecting seat 110, that is, the fixing structure 120 and the connecting seat 110 can be an integrated structure. Alternatively, the fixing structure 120 can be mounted on the connecting seat 110, that is, the fixing structure 120 and the connecting seat 110 can be a split structure. Alternatively, part of the fixing structure 120 can be formed on the connecting seat 110, and the other part of the fixing structure 120 can be mounted on the connecting seat 110, that is, part of the fixing structure 120 and the connecting seat 110 are an integrated structure, and the other part of the fixing structure 120 and the connecting seat 110 are a split structure.

[0061] In some possible implementation examples provided by the utility model, the mobile device connects the device main body and the mechanical arm 210 through the mechanical arm, and the mechanical arm is configured to adjust the relative position of the mechanical arm 210 and the device main body, for example, the height and / or rotation angle of the mechanical arm 210 relative to the device main body can be adjusted through the mechanical arm, so as to increase the movement range of the mechanical arm 210. Therefore, the posture of the mechanical arm 210 can be adjusted through the mechanical arm to clamp the clamping assembly 100 through the mechanical arm 210, and it can be understood that when the mechanical arm 210 clamps the to-be-clamped part 400 through the clamping assembly 100, the posture of the mechanical arm 210 can be adjusted through the mechanical arm to adjust the position of the to-be-clamped part 400 fixed on the clamping assembly 100, for example, the to-be-clamped part 400 can be located on the circumferential side of the device main body, and / or the to-be-clamped part 400 can be located on the top of the device main body.

[0062] As shown in FIG. 1, the utility model provides a clamping assembly 100, which is used for indirectly connecting or releasing a device main body and a to-be-clamped part 400. Figure 4 , Figure 5 ,Figure 10 , Figure 11 , Figure 12 As shown, in some possible embodiments provided by this utility model, the fixing structure 120 is configured to have a clamping space 121, which can accommodate the cylindrical member to be clamped 400. Thus, at least a portion of the cylindrical member to be clamped 400 can be accommodated and fixed within the clamping space 121 of the fixing structure 120, thereby reliably and stably fixing the cylindrical member to be clamped 400 to the connecting seat 110, achieving a reliable and stable connection between the member to be clamped 400 and the clamping assembly 100.

[0063] The clamping space 121 can be circular or other shapes including circular, so that the cylindrical clamping member 400 can be reliably and stably accommodated in the clamping space 121.

[0064] The cylindrical object to be clamped 400 may be part of the bottom, middle or top, and be accommodated and fixed in the clamping space 121 of the fixing structure 120.

[0065] like Figure 4 , Figure 5 , Figure 10 , Figure 11 , Figure 12 As shown, in some possible embodiments provided by this utility model, at least a portion of the clamping space 121 is circular, allowing the cylindrical clamping member 400 to be reliably and stably connected to the connecting seat 110 via the fixing structure 120. By configuring the diameter of the circle to be adjustable, the clamping space 121 can accommodate clamping members 400 of different sizes. That is, cylindrical clamping members 400 of different diameters can be reliably and stably connected to the connecting seat 110 via the fixing structure 120. This increases the clamping range of the clamping assembly 100, enabling the same clamping assembly 100 to clamp cylindrical clamping members 400 of different diameters, resulting in a wider range of applications and higher practicality.

[0066] Specifically, the diameter of the circle defined by the clamping space 121 can range from 4mm to 8mm. Since the diameter of the object to be clamped 400 (such as a cat toy) is typically 4mm to 8mm, by setting the diameter of the circle defined by the clamping space 121 to 4mm to 8mm, the same clamping assembly 100 can meet the clamping requirements of cat toys with different diameters, thus improving its practicality. Specifically, the diameter of the circle defined by the clamping space 121 can be any size from 4mm to 8mm, including 4mm, 5mm, 6mm, 7mm, 8mm, or any size between 4mm and 8mm.

[0067] At least part of the clamping space 121 is circular, which can be the entire clamping space 121, or part of the clamping space 121, thereby meeting the needs of different settings of the fixing structure 120.

[0068] As shown in Figure 1 , Figure 3 , Figure 4 In some possible embodiments provided by the utility model, the fixing structure 120 comprises a receiving hole 122 arranged at the connecting seat 110, and the inner wall of the receiving hole 122 is circumferentially and spacedly provided with a plurality of guide ribs 1221, one side of the guide rib 1221 towards the center of the receiving hole 122 is provided as a first guide surface 1222, and the first guide surface 1222 is obliquely arranged from the top end to the bottom end of the receiving hole 122 towards the center of the receiving hole 122. Thus, the plurality of guide ribs 1221 enclose the clamping space 121, such as the plurality of guide ribs 1221 enclosing the approximately circular clamping space 121 on one side of the receiving hole 122, so that the cylindrical clamping piece 400 can be accommodated in the clamping space 121 enclosed by the plurality of guide ribs 1221. Since the first guide surface 1222 of the guide rib 1221 is obliquely arranged, the diameter of the circular clamping space 121 gradually decreases from the top end to the bottom end of the receiving hole 122, that is, the clamping space 121 as a whole can be understood as a conical structure with a large-diameter end at the top end and a small-diameter end at the bottom end, thereby enabling the cylindrical clamping piece 400 with different diameters to be accommodated in the clamping space 121, and enabling the same receiving hole 122 to cooperate with the plurality of guide ribs 1221 with the first guide surface 1222 to achieve the accommodation function of the cylindrical clamping piece 400 with different diameters.

[0069] The clamping space 121 enclosed by the plurality of guide ribs 1221 is coaxially arranged with the receiving hole 122, thereby ensuring that the clamping piece 400 is centered in the receiving space without eccentricity. The clamping space 121 as a whole can be understood as a conical structure with a large-diameter end at the top end and a small-diameter end at the bottom end, thereby having a good guiding effect.

[0070] Specifically, the number of guide ribs 1221 can be three, four, five or other numbers. Specifically, as shown in Figure 4 The number of guide ribs 1221 is five.

[0071] As shown in Figure 1 and Figure 5 In some possible embodiments provided by the utility model, the side wall of the receiving hole 122 is provided with an adjusting hole 1223, and the fixing structure 120 further comprises an adjusting piece 123 connected with the adjusting hole 1223 and extendable to the inside of the receiving hole 122 and abutting against the clamping piece 400 to limit the movement of the clamping piece 400 relative to the connecting seat 110.

[0072] Thus, when the to-be-clamped part 400 is accommodated in the clamping space 121 surrounded by the plurality of guide ribs 1221, the length of the adjusting member 123 extending into the accommodating hole 122 is adjusted by connecting the adjusting member 123 with the adjusting hole 1223, the adjusting member 123 is abutted with the to-be-clamped part 400, the to-be-clamped part 400 is clamped between the adjusting member 123 and at least part of the guide rib 1221, the movement of the to-be-clamped part 400 relative to the connecting seat 110 is limited, so that the to-be-clamped part 400 can be reliably and stably fixed on the connecting seat 110, and the operation is simple and convenient.

[0073] It can be understood that when it is needed to separate the to-be-clamped part 400 from the clamping assembly 100, the length of the locking member 150 extending into the accommodating hole 122 can be adjusted by the adjusting member 123 and the adjusting hole 1223, the locking member 150 is separated from the to-be-clamped part 400 to release the to-be-clamped part 400, or the locking member 150 is separated from the adjusting hole 1223 to release the to-be-clamped part 400, and then the to-be-clamped part 400 is taken out of the accommodating hole 122, so that the separation and disassembly of the to-be-clamped part 400 from the clamping assembly 100 can be realized, and the operation is simple and convenient.

[0074] Specifically, the adjusting hole 1223 can be a threaded hole, and the adjusting member 123 can be a screw, which is rotationally connected with the connecting seat 110 through the threaded hole and can extend into the accommodating hole 122, and the length of the screw extending into the accommodating hole 122 can be adjusted.

[0075] As shown in Figure 5 , Figure 6 in some possible embodiments provided by the utility model, the adjusting hole 1223 is located between two adjacent guide ribs 1221, and at least two adjusting holes 1223 are arranged in the direction from the top end to the bottom end of the accommodating hole 122.

[0076] Since the first guide surface 1222 is arranged on the guide rib 1221 to guide the cylindrical to-be-clamped part 400 with different diameters, the cylindrical to-be-clamped part 400 with different diameters will be overlapped at different positions of the first guide surface 1222 of the guide rib 1221 after being inserted into the accommodating hole 122. By arranging a plurality of adjusting holes 1223 in the direction from the top end to the bottom end of the accommodating hole 122, the adjusting member 123 can pass through the adjusting holes 1223 at different positions and extend into the interior of the accommodating hole 122, so that the to-be-clamped part 400 at the corresponding position can be clamped between the adjusting member 123 and the guide rib 1221 to realize the fixation of the to-be-clamped part 400 at the corresponding position.

[0077] Specifically, the number of the adjusting holes 1223 can be two, three, four or other numbers. Specifically, as shown in Figure 6As shown, the number of adjustment holes 1223 is three. It can be understood that the number of adjustment members 123 is one, or, as Figure 1 As shown, the number of adjustment members 123 can be equal to the number of adjustment holes 1223, and one-to-one correspondence.

[0078] As shown, Figure 9 and Figure 10 In some possible embodiments provided by the utility model, the fixed structure 120 includes a clamping jaw 124 mounted on the connecting seat 110, and the clamping jaw 124 is configured to be clamped on the to-be-clamped member 400 or to release the to-be-clamped member 400.

[0079] In this embodiment, by mounting the clamping jaw 124 on the connecting seat 110, the to-be-clamped member 400 is clamped or released by the clamping jaw 124, so that the connection or separation of the to-be-clamped member 400 and the connecting seat 110 can be realized, which is simple in operation and simple in structure.

[0080] As shown, Figure 11 and Figure 12 In some possible embodiments provided by the utility model, the clamping jaw 124 includes two jaw parts 125, the jaw part 125 includes a connecting part 1251 and a clamping part 1252, the connecting part 1251 is hinged to the connecting seat 110, that is, each jaw part 125 is hinged to the connecting seat 110 through the connecting part 1251, so that the position of the clamping part 1252 of each jaw part 125 relative to the connecting seat 110 can be adjusted. By configuring the two clamping parts 1252 to be close to or away from each other, the two clamping parts 1252 are close to each other to enclose the clamping space 121, and the clamping space 121 is used to accommodate the cylindrical to-be-clamped member 400, so that the clamping operation on the cylindrical to-be-clamped member 400 can be realized by using the two clamping parts 1252 to be close to each other, which is simple in operation.

[0081] It can be understood that when the two clamping parts 1252 are away from each other, the to-be-clamped member 400 can be released, the separation of the to-be-clamped member 400 and the clamping jaw 124 is realized, and the separation of the to-be-clamped member 400 and the connecting seat 110 is realized, which is simple in operation.

[0082] In some possible embodiments provided by the utility model, the jaw part 125 further includes a hand-held part 1253, the hand-held part 1253 and the clamping part 1252 are located on both sides of the connecting part 1251, and the two hand-held parts 1253 are configured to be close to or away from each other to drive the two clamping parts 1252 to be away from or close to each other.

[0083] That is, the movement state of the two hand-held portions 1253 of the two claw portions 125 is opposite to the movement state of the two clamping portions 1252, when the two hand-held portions 1253 are away from each other, the two clamping portions 1252 are close to each other, when the two clamping portions 1252 are close to each other, the two hand-held portions 1253 are away from each other. Thus, by adjusting or operating the movement state of the two hand-held portions 1253 to be close to or away from each other, the operation of the two clamping portions 1252 to be away from or close to each other can be realized, and the operation of the clamping claw 124 to release or clamp the to-be-clamped piece 400 can be realized, which is simple and convenient to operate.

[0084] It can be understood that the hand-held portion 1253 can be manually driven to make the two hand-held portions 1253 close to or away from each other, and / or the two hand-held portions 1253 can be driven to close to or away from each other by an elastic mechanism.

[0085] As shown in Figure 9 , Figure 11 and Figure 12 , in some possible embodiments provided by the utility model, the clamping claw 124 further comprises a connecting shaft 126 installed on the connecting seat 110, the connecting portion 1251 is sleeved on the connecting shaft 126 and is rotationally connected with the connecting shaft 126, and the clamping claw 124 further comprises a torsional spring 127 sleeved on the connecting shaft 126, two torsional arms of the torsional spring 127 are connected with the two hand-held portions 1253 respectively, and the torsional spring 127 is configured to provide a rotational torsional force to the two hand-held portions 1253 to keep the two hand-held portions 1253 in a separated state, so that the two clamping portions 1252 are kept in a close state, at this time, the clamping claw 124 can be in an initial state or a clamping state, so that the clamping operation on the to-be-clamped piece 400 can be realized by using the two close clamping portions 1252, or the two close clamping portions 1252 do not clamp the to-be-clamped piece 400.

[0086] Further, the two hand-held portions 1253 are close to each other under the action of an external force to accumulate elastic potential energy of the torsional spring 127. For example, a user manually drives the two hand-held portions 1253 to be close to each other, so that the two hand-held portions 1253 drive the torsional spring 127 to deform and accumulate elastic potential energy, at this time, the two clamping portions 1252 are separated to release the clamped to-be-clamped piece 400, at this time, the clamping claw 124 can be in a released state. When the user's hand is away from the hand-held portion 1253, the torsional spring 127 releases the elastic potential energy, so that the two hand-held portions 1253 are away from each other, and further, the two clamping portions 1252 are close to each other, so that the clamping claw 124 is reset to the initial state or the clamping state.

[0087] As shown in Figure 9 , in some possible embodiments provided by the utility model, the connecting seat 110 is provided with a supporting groove 114 below the clamping space 121.

[0088] In the embodiment, since the support groove 114 is located directly below the clamping space 121, when the two clamping portions 1252 of the clamping jaw 124 clamp the to-be-clamped member 400, the bottom end of the to-be-clamped member 400 can be accommodated in the support groove 114, so that the support groove 114 plays a good supporting role on the to-be-clamped member 400, and the support groove 114 also plays a good limiting role on the to-be-clamped member 400, so that the bottom end of the to-be-clamped member 400 can be reliably and stably accommodated in the support groove 114, the possibility of shaking of the to-be-clamped member 400 is reduced, and the reliability and stability of the clamping assembly 100 in fixing the to-be-clamped member 400 are improved.

[0089] It can be understood that when the two clamping portions 1252 of the clamping jaw 124 clamp the to-be-clamped member 400, the bottom end of the to-be-clamped member 400 can also not be accommodated in the support groove 114, for example, the bottom end of the to-be-clamped member 400 is located above the support groove 114, so that when the mobile device moves, if the to-be-clamped member 400 slips with the clamping jaw 124 due to shaking, the bottom end of the to-be-clamped member 400 can fall and be accommodated in the support groove 114 located directly below the clamping space 121, and the support groove 114 plays a good supporting and limiting role on the to-be-clamped member 400, so that the entire to-be-clamped member 400 can still be stably fixed on the clamping assembly 100, the possibility of the to-be-clamped member 400 falling from the clamping jaw 124 due to slipping with the clamping jaw 124 is reduced, and the reliability and stability of the clamping assembly 100 in fixing the to-be-clamped member 400 are improved.

[0090] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 9 , in some possible implemented embodiments of the utility model, the clamping part 111 includes guide grooves 1111 located on opposite sides of the connecting seat 110, and the shapes of the guide grooves 1111 match the shape of the clamping jaw 211 of the manipulator 210. Thus, the guide grooves 1111 match the clamping jaw 211 on opposite sides of the connecting seat 110, so that the guide grooves 1111 have a certain limiting effect on the clamping jaw 211, the phenomenon of slipping of the clamping jaw 211 and the connecting seat 110 is reduced, and the clamping jaw 211 can reliably and stably clamp the connecting seat 110.

[0091] Specifically, as shown in Figure 3 , the manipulator 210 includes two clamping jaws 211, the free ends of the two clamping jaws 211 can approach or move away from each other, and the shapes of the two guide grooves 1111 on opposite sides of the connecting seat 110 match the two clamping jaws 211 respectively, so that one guide groove 1111 limits one clamping jaw 211, the phenomenon of slipping of the clamping jaw 211 and the connecting seat 110 is reduced, and the manipulator 210 can reliably and stably clamp the connecting seat 110.

[0092] As Figure 6 , Figure 7 and Figure 8 shown, in some possible embodiments provided by the utility model, one end of guide groove 1111 is provided with avoiding opening 1112 for avoiding claw 211, so that claw 211 can contact with the groove bottom of guide groove 1111 smoothly, in this way, claw 211 cooperates with guide groove 1111 and can play a good limiting effect, to ensure that mechanical hand 210 can reliably and stably clamp connecting seat 110.

[0093] Among them, the opening size of avoiding opening 1112 gradually increases from the inside to the outside of guide groove 1111, that is to say, the size of avoiding opening 1112 close to the outside of guide groove 1111 is greater than the size of avoiding opening 1112 close to the inside of guide groove 1111, and the wall surface of avoiding opening 1112 is outwardly expanded towards the outside of guide groove 1111. Among them, the size of avoiding opening 1112 close to the outside of guide groove 1111 is larger, which facilitates claw 211 to enter the inside of guide groove 1111 or move out of guide groove 1111 smoothly and accurately, so that mechanical hand 210 can still ensure the clamping precision in the case of insufficient precision. The size of avoiding opening 1112 close to the inside of guide groove 1111 is smaller, which can play a good limiting effect on claw 211, reduce the possibility of claw 211 slipping and shaking in guide groove 1111, and ensure that claw 211 and guide groove 1111 have stable and firm limiting effect.

[0094] As Figure 6 , Figure 7 and Figure 8 shown, in some possible embodiments provided by the utility model, the groove wall of guide groove 1111 is provided with second guide surface 1113 connected with the groove opening of guide groove 1111, and second guide surface 1113 is inclinedly arranged towards the middle part of guide groove 1111 from the direction of the groove opening to the groove bottom of guide groove 1111. That is to say, the setting of second guide surface 1113 makes the size of the groove opening of guide groove 1111 greater than the size of the groove bottom, the size of the groove opening of guide groove 1111 is larger, which facilitates claw 211 to enter the inside of guide groove 1111 or move out of guide groove 1111 smoothly and accurately, so that mechanical hand 210 can still ensure the clamping precision in the case of insufficient precision. The size of the groove bottom of guide groove 1111 is smaller, which can play a good limiting effect on claw 211, reduce the possibility of claw 211 slipping and shaking in guide groove 1111, and ensure that claw 211 and guide groove 1111 have stable and firm limiting effect.

[0095] Specifically, the second guide surface 1113 is located on the entire circumferential groove wall of the guide groove 1111, so that the clamping jaw 211 of the mechanical arm 210 has a large C angle guide design in X, Y and Z three directions, which ensures that the clamping jaw 211 of the mechanical arm 210 has sufficient guidance during pushing into the clamping part 111 and clamping the connecting seat 110, and the mechanical arm 210 can still ensure clamping accuracy in the case of insufficient accuracy.

[0096] As shown in Figure 1 , Figure 2 , Figure 9 , Figure 13 indicated, in some possible embodiments provided by the utility model, the cleaning assembly further comprises: a base 130 connected at the bottom of the connecting seat 110, so that the base 130 plays a good supporting role on the connecting seat 110. The clamping assembly 100 is configured to be placed on the bearing seat 300, and the shape of the base 130 is matched with the bearing groove 310 on the bearing seat 300.

[0097] As can be understood, as shown in Figure 13 , when the clamping assembly 100 is not needed to clamp the to-be-clamped part 400 for other operations (such as cat teasing operation), the mechanical arm 210 can place the clamping assembly 100 on the bearing seat 300 for storage. Since the positioning accuracy of the mobile device is poor, the tolerance is positive or negative 15 mm, and there is a possibility that the clamping assembly 100 cannot be accurately placed in the bearing groove 310 of the bearing seat 300. Therefore, in the embodiment, the shape of the base 130 and the bearing seat 300 is matched, so that the base 130 plays a certain guiding role, facilitating the base 130 to be quickly and accurately accommodated in the bearing groove 310 of the bearing seat 300, thereby enabling the entire clamping assembly 100 to be quickly and accurately placed on the bearing seat 300, and ensuring that the clamping assembly 100 can be quickly and accurately placed at a suitable position of the bearing seat 300.

[0098] As shown in Figure 1 , Figure 3 and Figure 9 indicated, in some possible embodiments provided by the utility model, the outer side wall of the base 130 is tapered, and the large-diameter end of the taper is connected with the connecting seat 110. That is, the small-diameter end of the taper is located at the bottom of the entire clamping assembly 100, so that when the entire clamping assembly 100 is placed in the bearing groove 310 of the bearing seat 300, the small-diameter end of the taper first extends into the bearing groove 310 of the bearing seat 300, and then the large-diameter end of the taper gradually falls into the bearing groove 310. As can be understood, Figure 13As shown, the bearing groove 310 is also tapered, thereby, through matching the tapered base 130 and the tapered bearing groove 310, a good guiding and limiting effect is achieved, so that the whole clamping assembly 100 can be quickly and accurately placed on the bearing seat 300, and the clamping assembly 100 can be quickly and accurately placed at the appropriate position of the bearing seat 300.

[0100] Since the fixing structure 120 is connected to the connecting seat 110 and located above the base 130, or the to-be-clamped part 400 fixed to the connecting seat 110 by the fixing structure 120 is located above the base 130, the whole clamping assembly 100 is prone to a situation of head-heavy and foot-light, and the clamping assembly 100 is prone to tilting and toppling after being placed in the bearing groove 310 of the bearing seat 300. In the embodiment, the counterweight 140 is arranged in the containing cavity enclosed by the base 130 and the connecting seat 110, and the weight of the bottom of the clamping assembly 100 is increased by using the counterweight 140, so that after the connecting seat 110 is loosened by the mechanical hand 210, the whole clamping assembly 100 can smoothly fall into the bearing groove 310 of the bearing seat 300 under the action of gravity, the situation of head-heavy and foot-light of the clamping assembly 100 is avoided, and the clamping assembly 100 is prevented from tilting and toppling in the bearing groove 310, so that the clamping assembly 100 can be accurately kept at the appropriate position.

Therefore, the detachable connection of the connecting seat 110 and the base 130 can be achieved, the disassembly and assembly are convenient, and the disassembly and assembly of the counterweight 140 are facilitated. Meanwhile, the locking part 150 is located in the inside of the base 130 and is not exposed on the side and the bottom of the base 130, that is, the appearance of the base 130 is not affected, so that the base 130 can be matched with the bearing seat 300 to play a good guiding role, and the appearance of the base 130 is improved, and the appearance of the clamping assembly 100 is improved.

[0102] Specifically, the locking piece 150 can be a connecting bolt, the connecting column 131 is provided with a threaded hole, and the connecting bolt passes through the through hole 1121 on the bottom plate 112 and is connected with the threaded hole of the connecting column 131, that is, the connection of the connecting seat 110 and the base 130 is realized, and the operation is simple.

[0103] As shown in Figure 1 some possible embodiments provided by the utility model, the counterweight block 140 is provided with a notch structure 141 avoiding the connecting column 131, and the connecting column 131 and the notch structure 141 are matched to limit the movement of the counterweight block 140 relative to the base 130. Thus, the function of the connecting column 131 is diversified, so that the connecting column 131 is used for being connected with the locking piece 150, and meanwhile, the connecting column 131 and the notch structure 141 on the counterweight block 140 are matched to limit the movement of the counterweight block 140 relative to the base 130, so that the counterweight block 140 can be reliably and stably fixed on the base 130, the possibility of the counterweight block 140 shaking relative to the base 130 and the whole clamping assembly 100 shaking is reduced, and the clamping assembly 100 can be reliably and stably accommodated in the accommodating groove of the bearing seat 300, and the possibility of the clamping assembly 100 shaking in the accommodating groove is reduced. Meanwhile, the structure for fixing the counterweight block 140 is simplified, the manufacturing cost is reduced, and the design requirements of compact structure and small volume of the clamping assembly 100 are met.

[0104] Further, as shown in Figure 1 the notch structure 141 is located on the opposite sides of the counterweight block 140, and the connecting column 131 is two, the two connecting columns 131 are inserted into the two notch structures 141 to limit the counterweight block 140 from the two sides of the counterweight block 140, and the counterweight block 140 is equivalent to being clamped between the two connecting columns 131. This kind of setting makes the counterweight block 140 be reliably and stably limited between the two connecting columns 131. Meanwhile, the notch structure 141 is located on the side of the counterweight block 140, and compared with the notch structure 141 being located in the middle of the counterweight block 140, the processing is facilitated.

That is, by using the mutual cooperation of the suction accessory and the suctioned accessory, the position of the base 130 located in the bearing groove 310 can be corrected, so that the base 130 can be located at a suitable position of the bearing seat 300, the clamping assembly 100 is carried on the bearing seat 300 in a suitable posture, for example, the guide groove 1111 of the clamping part 111 can be in a horizontal position, the mechanical hand 210 can be quickly and accurately matched with the clamping part 111 to clamp and move the clamping assembly 100 away from the bearing seat 300.

[0106] The suction accessory and the sucked accessory can be magnetic suction structures, for example, one of the suction accessory and the sucked accessory can be a magnetic piece, and the other can be a metal piece, an alloy piece, or the like.

[0107] In some possible embodiments, the counterweight 140 is provided as the sucked accessory, and the suction accessory is arranged on the bearing seat 300. For example, the magnet is arranged on the bearing seat 300, and the counterweight 140 is provided as a metal piece or an alloy piece with magnetic properties. In this way, the arrangement of the sucked accessory can be simplified, the compact design requirement of the clamping assembly 100 can be met, and the manufacturing cost of the clamping assembly 100 can be reduced.

[0108] Specifically, the counterweight 140 can be cast iron. The cast iron has the advantages of high density, high strength, and corrosion resistance, so that a smaller volume has a greater weight, the stability of the entire clamping assembly 100 placed on the bearing seat 300 can be improved, and the design requirement of a smaller volume of the clamping assembly 100 can be met. Meanwhile, the cast iron has magnetic properties, so that the cast iron cooperates with the magnet on the bearing seat 300 to correct the position of the base 130 located in the bearing groove 310, so that the base 130 can be located at a suitable position of the bearing seat 300.

[0109] The utility model also provides a kind of cleaning system, and cleaning system includes base station and the mobile device of preceding description.
