Description

Technical Field

[0001] The present disclosure relates to the technical field of cleaning equipment, and in particular, to a driving device, a cleaning equipment and a cleaning system. Background Art

[0002] With the continuous development of cleaning equipment manufacturing technology, intelligent cleaning devices are increasingly being used in household life. For example, cleaning robots can greatly facilitate room cleaning. When faced with complex usage scenarios, the cleaning components of cleaning robots need to perform multiple movements such as rotation, lifting, and swinging. However, current cleaning robots require multiple motors to provide driving force for these movements, resulting in a complex mechanical structure, high failure rate, and high manufacturing cost.

[0005] The lifting assembly includes a rotating part and a lifting part. The rotating part is arranged on the power output shaft. When the power output shaft rotates along the first rotation direction, the rotating part rotates with the power output shaft.

[0006] The swing assembly includes a swing member, which is arranged on the power output shaft. When the power output shaft rotates along the first rotation direction, the swing member rotates along with the power output shaft.

[0007] The drive device provided in the embodiments of the present disclosure has a drive member that drives the power output shaft to rotate in a first rotational direction, thereby not only rotating the power output shaft but also driving the lifting member to lift and lower, and the entire output mechanism to swing.

[0047] In order to make the purpose, technical solutions and advantages of the present disclosure more apparent, example embodiments according to the present disclosure will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited to the example embodiments described herein. Based on the embodiments of the present disclosure described in this disclosure, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present disclosure.

[0048] In the following description, a large amount of detail is provided to facilitate a thorough understanding of the present disclosure. However, it will be appreciated by those skilled in the art that the following description merely illustrates preferred embodiments of the present disclosure, and the present disclosure may be implemented without one or more of these details. Furthermore, to avoid confusion with the present disclosure, some technical features well known in the art are not described in detail.

[0049] To thoroughly understand the embodiments of the present disclosure, detailed structures will be provided in the following description. It should be understood that the implementation of the embodiments of the present disclosure is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of the present disclosure are described in detail below, but in addition to these detailed descriptions, the present disclosure may also have other embodiments.

[0050] In one embodiment of the present disclosure, a driving device 10 is provided. The driving device 10 can be used in the field of household appliances or engineering manufacturing, etc. The driving device 10 is mainly used in cleaning equipment. Therefore, according to another aspect of the present disclosure, a cleaning device is also provided. The cleaning equipment includes but is not limited to a cleaning robot, a sweeping and mopping robot, or an electric mopping machine. According to another aspect of the disclosure, a cleaning system is also provided, which includes a base station and the above-mentioned cleaning equipment. The driving device 10 and the cleaning equipment of the embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0051] In the related art, cleaning equipment such as cleaning robots are typically equipped with three drive devices (i.e., a rotary drive device, a lifting drive device, and a swing drive device). During operation, the rotary drive device can be used to drive the cleaning element (for example, a mop) to rotate on the ground or other surface to be cleaned to clean the surface. The lifting drive device can be used to drive the mop up and down. When the cleaning robot moves to an obstacle such as a carpet, the lifting drive device can drive the mop up to overcome the obstacle, thereby preventing the mop from getting stuck or contacting the obstacle. After crossing the obstacle, the lifting drive device can drive the mop down to the surface to be cleaned so that cleaning can continue. The swing drive device can drive the mop to swing outward to achieve extreme edge cleaning and avoid missing cleaning areas along the edges. However, the three drive devices require a large amount of space, resulting in very tight space inside the cleaning equipment, seriously affecting the layout of components that also require space, such as the dust box and / or water tank. As a result, in order to avoid increasing the overall size of the cleaning equipment, these components can only be reduced in size, resulting in limited functionality and poor product performance of the cleaning equipment. Furthermore, the three drive units are expensive and require three circuit systems, which increases the manufacturing cost of the cleaning equipment. Furthermore, the three drive units inevitably lead to a higher failure rate of the cleaning equipment, which in turn increases the cost of use and reduces product competitiveness.

[0052] The driving device 10 provided in the embodiment of the present disclosure can be used to drive the cleaning member to rotate, to drive the cleaning member to lift and lower, and to drive the cleaning member to swing outward, thereby taking into account the functions of cleaning, lifting and swinging outward, and thus improving the above-mentioned problems.

[0053] Specifically, refer to Figure 1 and Figure 2 The driving device 10 includes a fixed seat 11 and an output mechanism 12 provided on the fixed seat 11. The output mechanism 12 includes a power assembly 121, a lifting assembly 122, and a swing assembly 123. The power assembly 121 includes a driving member 1211 and a power output shaft 1212. The power output shaft 1212 rotates around its own axis under the action of the driving member 1211. The lifting assembly 122 includes a rotating member 1221 and a lifting member 1223. The rotating member 1221 is provided on the power output shaft 1212. The rotating member 1221 is configured to rotate along with the power output shaft 1212 when the power output shaft 1212 rotates along a first rotation direction. The lifting member 1223 is connected to the rotating member 1221 and is lifted and lowered in the axial direction relative to the power output shaft 1212 when the rotating member 1221 rotates. The swing assembly 123 includes a swing member 1231 . The swing member 1231 is disposed on the power output shaft 1212 . The swing member 1231 is configured to rotate along with the power output shaft 1212 when the power output shaft 1212 rotates along a first rotation direction.

[0054] The driving member 1211 is disposed on one side of the power output shaft 1212 and is connected to the power output shaft 1212. Under the action of the driving member 1211, the power output shaft 1212 can rotate clockwise or counterclockwise around its own axis.

[0055] The first direction can be expressed as a clockwise direction or a counterclockwise direction. The following is based on the first direction as the counterclockwise direction ( Figure 1 It should be understood that when the first direction is clockwise, the operating principle of the driving device 10 is the same as when the first direction is counterclockwise, and will not be described in detail here.

[0056] The swing assembly 123 is disposed at a position further away from the fixing base 11 than the lifting assembly 122 .

[0057] The lifting member 1223 is sleeved on the outer side of the rotating member 1221 . When the power output shaft 1212 drives the rotating member 1221 to rotate, the lifting member 1223 is displaced in the axial direction of the rotating member 1221 .

[0058] For example, when the driving member 1211 drives the power output shaft 1212 to rotate counterclockwise about its own axis, the power output shaft 1212 can drive the connected rotating member 1221 and the swinging member 1231 to rotate synchronously. At this time, the lifting member 1223 can move vertically upward relative to the rotating member 1221 to achieve the lifting function of the lifting assembly 122, and the swinging member 1231 can drive the output mechanism 12 to reciprocate to achieve the swinging function of the output mechanism 12.

[0059] In the drive device 10 disclosed herein, when the driving member 1211 drives the power output shaft 1212 to rotate in a first rotational direction, not only does the power output shaft 1212 rotate, but it also drives the lifting member 1223 to rise and fall, and the entire output mechanism 12 to swing. When applied to a cleaning device, it can be used to drive the cleaning member to rotate for cleaning, lift the cleaning member to overcome obstacles, or lift the cleaning member to achieve dry and wet separation during cleaning. It can also be used to swing the cleaning member outward for ultimate edge cleaning, avoiding missed cleaning areas along the edges. In this way, the drive device 10 can simultaneously perform cleaning, lifting, and swing functions, thereby replacing traditional rotary drive devices, lifting drive devices, and swing drive devices. When the drive device 10 is applied to a cleaning device, the cleaning device can eliminate two sets of drive devices, thereby saving a significant amount of space for the layout of other components. For example, the saved space can be used to increase the volume of the dust box and / or water tank to improve the product performance of the cleaning device. Furthermore, by eliminating two sets of drive devices, the cleaning device can also eliminate two sets of circuit systems, significantly reducing its manufacturing cost. In addition, the cleaning equipment has fewer parts, its failure rate can be reduced, the cost of use can be reduced, and the product is more competitive.

[0060] In one disclosed embodiment, Figure 3 and Figure 4 The rotating member 1221 is sleeved on the power output shaft 1212, and one of the rotating member 1221 and the lifting member 1223 is provided with a rotating groove 1222, and the other is provided with a plug-in member 1223b, and the plug-in member 1223b is slidably provided in the rotating groove 1222.

[0061] For example, the connector 1223b can be set on the inner wall of the lifting member 1223, and the rotating groove 1222 can be set on the outer wall of the rotating member 1221. Conversely, the connector 1223b can also be set on the outer wall of the rotating member 1221, and the rotating groove 1222 can also be set on the outer wall of the lifting member 1223. By sliding the connector 1223b in the rotating groove 1222, the relative vertical movement between the rotating member 1221 and the lifting member 1223 can be achieved.

[0062] For example, the connector 1223b can move from the lower end to the upper end of the rotating slot 1222, and the lifting member 1223 can then move upward along the axis of the rotating member 1221. Conversely, the connector 1223b can move from the upper end to the lower end of the rotating slot 1222, and the lifting member 1223 can then move downward along the axis of the rotating member 1221.

[0063] Optionally, there can be multiple connectors 1223b, and multiple connectors 1223b can be set on opposite sides of the inner wall of the lifting member 1223, and the rotating groove 1222 can be set on the outer wall of the rotating member 1221. The multiple connectors 1223b can make the connection between the rotating member 1221 and the lifting member 1223 more convenient.

[0064] In other embodiments, a rotating slot 1222 is provided on the inner wall of the lifting member 1223, and a plurality of plug-in members 1223b are provided on the outer wall of the rotating member 1221. The working principles of the two are the same as those described above and will not be repeated here.

[0065] Alternatively, the connector 1223b may be a pin shaft, and a through hole may be provided on the side wall of a component in the rotating component 1221 or the lifting component 1223, with a part of the connector 1223b inserted in the through hole and the other part in the rotating slide 1222, so that the maintenance and replacement of the connector 1223b is more convenient and quick, greatly saving maintenance time and labor costs.

[0066] In the above embodiment, when the power output shaft 1212 drives the rotating member 1221 to rotate, the plug-in member 1223b can slide within the rotating slot 1222, thereby achieving relative vertical movement between the lifting member 1223 and the rotating member 1221. This effectively improves the rotation efficiency of the lifting assembly 122 and simplifies the connection structure of the lifting assembly 122.

[0067] In one embodiment of the present disclosure, see Figure 7 The lifting member 1223 includes a sleeve 1223 a , and the sleeve 1223 a is sleeved outside the rotating member 1221 .

[0068] The connector 1223b can be a protrusion protruding from the inner wall of the sleeve 1223a, and the sleeve 1223a is sleeved on the outside of the rotating member 1221, so that the connector 1223b can be set in the rotating groove 1222 of the rotating member 1221, and the connector 1223b can slide along the rotating groove 1222, so that the rotating member 1221 can drive the lifting member 1223 to move in the vertical direction.

[0069] In the above embodiment, the sleeve 1223a and the connector 1223b can be connected and arranged to realize the integrated processing of the lifting member 1223, greatly reducing the processing difficulty of the lifting member 1223, simplifying the structure of the lifting member 1223 and reducing the number of parts.

[0070] In one embodiment of the present disclosure, Figure 4 and Figure 5 The rotating chute 1222 includes two groups of symmetrically arranged first spiral segments 1222e and second spiral segments 1222f. The first spiral segments 1222e and the second spiral segments 1222f in each group are connected. The two symmetrically arranged first spiral segments 1222e are connected, and the two symmetrically arranged second spiral segments 1222f are connected. The first spiral segments 1222e and the second spiral segments 1222f are both arranged along the circumference of the rotating member 1221. Alternatively, refer to Figure 6 The rotating groove 1222 includes two thread grooves 1222i with opposite rotation directions, and the two thread grooves 1222i are both arranged along the circumference of the rotating member 1221.

[0071] The rotation directions of the first helical segment 1222e and the second helical segment 1222f can be opposite. Optionally, when the power output shaft 1212 drives the rotating member 1221 to rotate counterclockwise, the second helical segment 1222f can be an oblique groove or a vertical groove, and the first helical segment 1222e can be an oblique groove. Conversely, when the power output shaft 1212 drives the rotating member 1221 to rotate clockwise, the first helical segment 1222e can be an oblique groove or a vertical groove, and the second helical segment 1222f can be an oblique groove.

[0072] In some embodiments, the rotating chute 1222 includes two groups of symmetrically arranged first spiral segments 1222e and second spiral segments 1222f. The first spiral segments 1222e and the second spiral segments 1222f in each group are connected. The two symmetrically arranged first spiral segments 1222e are connected, and the two symmetrically arranged second spiral segments 1222f are connected. The other group of first spiral segments 1222e and second spiral segments 1222f correspond to Figure 5 The fourth spiral segment 1222h and the third spiral segment 1222g, that is, the first spiral segment 1222e, the second spiral segment 1222f and the fourth spiral segment 1222h, and the third spiral segment 1222g are symmetrically arranged, the symmetrically arranged first spiral segment 1222e is connected to the fourth spiral segment 1222h, and the symmetrically arranged second spiral segment 1222f is connected to the third spiral segment 1222g.

[0073] In other embodiments, see Figure 6The rotating groove 1222 can be configured as the thread groove of a reciprocating screw, that is, it includes two thread grooves 1222i with opposite rotation directions, both of which are arranged along the circumference of the rotating member 1221. The pitch of the two thread grooves 1222i can be the same or different. When the power output shaft 1212 rotates in the first rotation direction, the reciprocating motion of the lifting member 1223 is achieved by the thread groove of the reciprocating screw.

[0074] In the above embodiment, the first spiral segment 1222e and the second spiral segment 1222f of the spiral groove 1222, or the thread groove 1222i of the spiral groove 1222, can realize the vertical movement of the lifting member relative to the rotating member, thereby realizing the lifting function of the driving device 10. While ensuring the lifting function of the lifting component 122, the connection structure of the lifting component 122 is simplified, thereby effectively improving the reliability of the driving device 10 and reducing the failure rate of the driving device 10.

[0075] In one embodiment of the present disclosure, Figure 4 and Figure 5 The rotating chute 1222 includes two groups of symmetrically arranged first chute segments 1222a, first spiral segments 1222e and second spiral segments 1222f. The first chute segment 1222a in each group is connected between the first spiral segment 1222e and the second spiral segment 1222f. The two symmetrically arranged first spiral segments 1222e are connected, and the two symmetrically arranged second spiral segments 1222f are connected. The first spiral segments 1222e and the second spiral segments 1222f are both arranged along the circumference of the rotating member. Alternatively, the rotating chute 1222 includes two groups of symmetrically arranged The first groove segment 1222a, the first spiral segment 1222e, the second spiral segment 1222f, and the second groove segment 1222b, the first groove segment 1222a in each group is connected between the first spiral segment 1222e and the second spiral segment 1222f, one second groove segment 1222b is connected between two symmetrically arranged first spiral segments 1222e, and another second groove segment 1222b is connected between two symmetrically arranged second spiral segments 1222f, and the first spiral segment 1222e and the second spiral segment 1222f are both arranged along the circumference of the rotating part.

[0076] In other embodiments, the rotating chute 1222 further includes two symmetrically arranged first chute sections 1222a, and the other first chute section 1222a corresponds to Figure 5 The third groove section 1222c in the embodiment, that is, the first groove section 1222a and the third groove section 1222c are symmetrically arranged; and one first groove section 1222a is connected between the first spiral section 1222e and the second spiral section 1222f, and the other first groove section 1222a is connected between the fourth spiral section 1222h and the third spiral section 1222g, that is, corresponding to Figure 5The first slot segment 1222a is connected between the first spiral segment 1222e and the second spiral segment 1222f, and the third slot segment 1222c is connected between the fourth spiral segment 1222h and the third spiral segment 1222g.

[0077] In other embodiments, the rotating chute 1222 further includes two symmetrically arranged second chute sections 1222b, and the other second chute section 1222b corresponds to Figure 5 The fourth slot segment 1222d, that is, the second slot segment 1222b and the fourth slot segment 1222d are symmetrically arranged; and one second slot segment 1222b is connected between two symmetrically arranged first spiral segments 1222e, and another second slot segment 1222b is connected between two symmetrically arranged second spiral segments 1222f, that is, corresponding to Figure 5 The second groove section 1222b is connected between the second spiral section 1222f and the third spiral section 1222g, and the fourth groove section 1222d is connected between the first spiral section 1222e and the fourth spiral section 1222h. The first spiral section 1222e and the second spiral section 1222f may have opposite rotation directions, and symmetrically, the third spiral section 1222g and the fourth spiral section 1222h may have opposite rotation directions.

[0078] For example, taking the rotating slot 1222 as an example, the rotating slot 1222 is provided on the outer peripheral wall of the rotating member 1221, and the first slot segment 1222a, the first spiral segment 1222e, and the second spiral segment 1222f respectively correspond to the planes where the third slot segment 1222c, the fourth spiral segment 1222h, and the third spiral segment 1222g are located relative to the central axis of the rotating member 1221 (see Figure 4 or the dotted line in 5) are symmetrically arranged; the second groove section 1222b and the fourth groove section 1222d are relative to another plane where the central axis of the rotating member 1221 is located (see Figure 4 When the rotating chute 1222 is arranged on the lifting member 1223, the same principle applies, which will not be described in detail here.

[0079] The symmetrically arranged rotating chute 1222 allows the lifting member 1223 to descend after reaching its highest point as the power output shaft 1212 continues to rotate. Therefore, when the power output shaft 1212 rotates in the first rotational direction, the lifting member 1223 performs a reciprocating motion of ascending and descending.

[0080] In the above embodiment, the portion of the lifting member 1223 disposed within the rotating chute 1222 can ascend or descend along the first spiral segment 1222e and the second spiral segment 1222f, respectively. Furthermore, the lifting member 1223 can be positioned at its highest and lowest points using the first chute segment 1222a and the second chute segment 1222b, respectively, thereby achieving reciprocating ascending and descending motion for the lifting member 1223 and effectively ensuring the flexibility and convenience of use of the lifting assembly 122.

[0081] In one embodiment of the present disclosure, see Figure 8 The output mechanism 12 further includes a box body 124 , the driving member 1211 is disposed in the box body 124 , a guide structure is formed between the box body 124 and the lifting member 1223 , and the lifting member 1223 is guided to move up and down by the guide structure.

[0082] A gear assembly (not shown in the figure) may be provided in the box body 124 , and the gear assembly is connected to the driving member 1211 to drive the power output shaft 1212 to rotate around its own axis.

[0083] In the above embodiment, the lifting member 1223 can rise or fall along the guide structure, avoiding the displacement of the lifting member 1223 during movement, effectively ensuring the stability of the lifting assembly 122 during movement, and thereby improving the structural stability of the driving device 10.

[0084] In one embodiment of the present disclosure, see Figure 7 and Figure 8 The guide structure includes a guide groove 125 and a guide portion 126, the guide portion 126 is at least partially slidably arranged in the guide groove 125, the guide groove 125 is arranged on the outer wall of the box body 124, and the guide portion 126 protrudes from the outer wall of the lifting member 1223; or, the guide groove 125 is arranged on the outer wall of the lifting member 1223, and the guide portion 126 protrudes from the outer wall of the box body 124.

[0085] The guide groove 125 is in the shape of an elongated strip, and the length direction of the guide groove 125 is parallel to the axial direction of the power output shaft 1212 .

[0086] In the above embodiment, the guide portion 126 can be slidably disposed in the guide groove 125 so that the lifting member 1223 can stably slide along the outer wall of the box body 124, further improving the stability of the lifting assembly 122 during movement and the firmness of the driving device 10.

[0087] In one embodiment of the present disclosure, Figure 1 、 Figure 3 and Figure 9The fixed seat 11 includes a base 112, a track groove 111 provided on the base 112 and a blocking member 113 connected to the base 112, and when the swing member 1231 rotates to abut against the blocking member 113, the output mechanism 12 swings along the track groove 111.

[0088] The shape and length of the track groove 111 may be adapted to the motion track of the output mechanism 12 , so that the output mechanism 12 may swing along the track groove 111 .

[0089] In the above embodiment, the track groove 111 provided on the base 112 can enable the output mechanism 12 to have a more stable moving state when swinging, thereby effectively improving the stability and smoothness of the movement of the output mechanism 12 .

[0090] In one embodiment of the present disclosure, Figure 1 、 Figure 3 、 Figure 8 、 Figure 9 and Figure 10 The base 112 is further provided with an avoidance groove 114 , and a portion of the output mechanism 12 close to the base 112 passes through the avoidance groove 114 so as to swing along the avoidance groove 114 when the swinging member 1231 rotates to abut against the blocking member 113 .

[0091] The avoidance groove 114 may be a through groove provided on the base 112 , and the shape of the avoidance groove 114 may be adapted to the motion trajectory of the output mechanism 12 .

[0092] When the swinging member 1231 pushes the output mechanism 12 to swing, the output mechanism 12 passes through a portion of the avoidance groove 114 and can move along the shape of the avoidance groove 114. In addition, the avoidance groove 114 allows the output mechanism 12 to pass through a portion of the base 112 provided with a cleaning member to achieve a swing cleaning operation of the output mechanism 12.

[0093] In the above embodiment, the output mechanism 12 can swing along the shape of the avoidance groove 114, and the avoidance groove 114 can set a cleaning member on one end of the output mechanism 12 close to the base 112 to realize the back-and-forth swinging cleaning operation, which effectively ensures the stability of the swinging motion of the output mechanism 12 and the practicality of the output mechanism 12.

[0094] In one embodiment of the present disclosure, Figure 8 and Figure 9 The output mechanism 12 further includes a box body 124 , a protrusion 1241 is provided at the lower portion of the box body 124 , and the protrusion 1241 is slidably disposed in the track groove 111 .

[0095] The track groove 111 may be in an arc shape, and the protrusion 1241 is disposed in the track groove 111 to drive the box body 124 to reciprocate in the track groove 111 , thereby achieving the swing of the output mechanism 12 .

[0096] In the above embodiment, the protrusion 1241 can be embedded in the track groove 111. When the output mechanism 12 swings, the protrusion 1241 can slide in the track groove 111. As a result, the output mechanism 12 can have greater stability when swinging, effectively improving the reliability of the output mechanism 12.

[0097] In one embodiment of the present disclosure, see Figure 9 The blocking member 113 includes a first baffle 1131 and a second baffle 1132 , which are respectively fixed to the base 112 , and the first baffle 1131 and the second baffle 1132 are respectively disposed on opposite sides of the output mechanism 12 .

[0098] The first baffle 1131 and the second baffle 1132 may be detachably connected to the base 112 .

[0099] The distance between the first baffle 1131 and the second baffle 1132 is smaller than the rotation diameter of the rotating member 1221, and the heights of the first baffle 1131 and the second baffle 1132 are higher than the swinging member 1231, so that when the swinging member 1231 rotates around the power output shaft 1212, it can respectively resist the first baffle 1131 and the second baffle 1132 and generate a force.

[0100] The power output shaft 1212 can drive the swinging member 1231 to rotate. During this rotation, when the swinging member 1231 abuts the first baffle 1131, since the first baffle 1131 is fixed to the base 112, the force generated by the two forces pushes the output mechanism 12 toward the second baffle 1132. When the swinging member 1231 abuts the second baffle 1132, since the second baffle 1132 is fixed to the base 112, the force generated by the two forces pushes the output mechanism 12 toward the first baffle 1131. As a result, the output mechanism 12 can swing between the first baffle 1131 and the second baffle 1132.

[0101] In the above embodiment, the swinging member 1231 generates forces against the first baffle 1131 and the second baffle 1132, respectively, allowing the output mechanism 12 to swing back and forth between the first baffle 1131 and the second baffle 1132. When applied to a cleaning device, the cleaning member can be swung outward to achieve ultimate edge cleaning, avoiding missed cleaning areas along the edges. It can also repeatedly clean key cleaning areas, effectively improving the cleaning effect. Furthermore, the structure of the output mechanism 12 can be further simplified, reducing the difficulty and cost of manufacturing the output mechanism 12.

[0102] In one embodiment of the present disclosure, see Figure 3 The lifting assembly 122 further includes a first one-way rotating body 1224, and the rotating member 1221 is connected to the power output shaft 1212 via the first one-way rotating body 1224. The swinging assembly 123 further includes a second one-way rotating body 1232, and the swinging member 1231 is connected to the power output shaft 1212 via the second one-way rotating body 1232.

[0103] The first one-way rotating body 1224 and the second one-way rotating body 1232 have the characteristic of one-way rotation. The first one-way rotating body 1224 and the second one-way rotating body 1232 can be one-way rotation bearings.

[0104] For example, when the power output shaft 1212 rotates counterclockwise, the first unidirectional rotating body 1224 can drive the lifting assembly 122 to move in the vertical direction, and the second unidirectional rotating body 1232 can drive the swinging assembly 123 to swing. When the power output shaft 1212 rotates clockwise, the lifting assembly 122 cannot move, and the swinging assembly 123 cannot swing.

[0105] In the above embodiment, through the first one-way rotating body 1224 and the second one-way rotating body 1232, the output mechanism 12 can have different motion states when using one power output shaft 1212, which greatly saves the space of the output mechanism 12, improves the motion efficiency of the output mechanism 12 and reduces the failure rate.

[0106] In one embodiment of the present disclosure, a cleaning device is provided, comprising a cleaning member and the driving device 10 as described above. Figure 3The cleaning member (not shown) is connected to the driving device 10 via the connecting member 20 so as to be rotated, lifted, or swung by the driving device 10. Specifically, the connecting member 20 is disposed on the power output shaft 1212. The cleaning member is connected to the power output shaft 1212 via the connecting member 20 so as to rotate with the power output shaft 1212 or to oscillate based on the swinging member 1231. In addition, the connecting member 20 is disposed on the power output shaft 1212 and is slidable along the axial direction of the power output shaft 1212. The connecting member 20 is connected to the lifting member 1223 so as to drive the cleaning member to rise and fall when the lifting member 1223 is raised or lowered.

[0107] The connecting member 20 can be connected to the end of the power output shaft 1212 near the base 112, or can be sleeved on the end of the power output shaft 1212 near the base 112. The cleaning member can be represented as a tool for cleaning and maintenance. For example, the cleaning member can be a mop, a side brush, a roller brush, a drum, or other components that can be used for cleaning.

[0108] In the above embodiment, the cleaning member can be connected to the power output shaft 1212 or the lifting member 1223 via the connecting member 20, so that when the power output shaft 1212 or the lifting member 1223 moves, the cleaning member can rotate, rise and fall or swing accordingly, effectively improving the cleaning efficiency and practicality of the cleaning device.

[0109] In one embodiment of the present disclosure, see Figure 3 The connecting member 20 is provided with an elastic member 30 on its outer cover, and the elastic member 30 applies a force to the cleaning member through the connecting member 20 .

[0110] The elastic member 30 can be elastically deformed when subjected to an external force and can return to its original shape after the external force is removed.

[0111] The edge of the connecting member 20 near one end of the base 112 is provided with an abutment portion 201. The elastic member 30 can press against the abutment portion 201 of the connecting member 20, so that the connecting member 20 has sufficient downward pressure to ensure a tight fit between the connecting member 20 and the cleaning member. The abutment portion 201 presses on the lifting member 1223. When the lifting member 1223 rises, it drives the connecting member 20 upward through the abutment portion 201, thereby driving the cleaning member upward. At this time, the elastic member 30 is in a compressed state. After reaching the highest point, the lifting member 1223 begins to descend, and the compressed elastic member 30 begins to recover. At this time, the restoring force of the elastic member 30 provides downward pressure for the connecting member 20.

[0112] In the above embodiment, the connecting member 20 applies a force to the cleaning member through the elastic member 30, which can effectively improve the connection firmness between the connecting member 20 and the cleaning member, thereby ensuring the practicality and reliability of the cleaning device.

[0113] The cleaning device disclosed in the present invention is connected to the power output shaft 1212 through the connecting member 20. When the power output shaft 1212 of the driving device 10 is rotated clockwise ( Figure 1 When the cleaning device 10 is rotated in the BA direction shown in the figure, the cleaning member is driven to rotate continuously to clean the floor or the surface of an object. When the cleaning device encounters obstacles such as carpets during the cleaning process, the power output shaft 1212 of the driving device 10 can be adjusted to rotate counterclockwise, and the cleaning member is driven to move vertically upward through the lifting assembly 122 to avoid the obstacle. When the cleaning device cleans the edge area of the room, the power output shaft 1212 can be used to rotate counterclockwise to drive the swinging member 1231 to interact with the blocking member, thereby realizing the outward swing of the cleaning member. In this way, the cleaning device of the present invention can drive the cleaning member to rotate for cleaning work, lift the cleaning member to perform obstacle-crossing work, and drive the cleaning member to swing outward to achieve extreme edge cleaning to avoid missing cleaning areas along the edge. While simplifying the mechanical structure of the cleaning device, it also reduces the cost of processing and manufacturing, effectively reduces the failure rate and improves the user experience.
