Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, and in particular to a driving device, a cleaning device and a cleaning system. Background Art

[0002] With the improvement of living standards, people's requirements for the quality of life are getting higher and higher. Cleaning equipment has a good cleaning effect on dirt such as dust, water stains and oil stains, so it is becoming more and more popular.

[0003] For example, most cleaning equipment such as sweeping and mopping robots use a rotating cleaning member (such as a mop) for cleaning. The current sweeping and mopping robots are equipped with a set of rotating drive devices and a set of lifting drive devices. The rotating drive device can drive the mop to rotate, so that it can be used for sweeping and supporting the floor. The lifting drive device can drive the mop to rise and fall, so that it can be used to travel over obstacles to avoid the mop getting stuck, or to lift the mop when sweeping the floor alone, which is conducive to the separation of dry and wet to ensure the cleaning effect.

[0004] However, the rotation drive device and the lifting drive device occupy a large space and are expensive, which will result in a high manufacturing cost of the sweeping and mopping robot, a relatively tight space, and is not conducive to the layout of other components. Utility Model Content

[0051] In the following description, a large number of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only illustrates preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.

[0052] According to one aspect of the utility model, a driving device is provided. The driving device can be used to drive the mop and other components to rotate and lift, so as to meet the user's usage needs. The driving device can be applied to cleaning equipment. Therefore, according to another aspect of the utility model, 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. The driving device and the cleaning device of the embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

[0053] The inventor has found through creative work that in the related art, two sets of driving devices (i.e., a rotating driving device and a lifting driving device) are usually provided in cleaning equipment such as a sweeping and mopping robot. During the operation of the cleaning equipment, the rotating driving device can be used to drive a cleaning member such as a mop to rotate on the ground or other cleaned surface to clean the cleaned surface. The lifting driving device can be used to drive the mop to rise and fall. When the sweeping and mopping robot moves to an obstacle such as a carpet, the lifting driving device can drive the mop to rise to cross the obstacle, thereby preventing the mop from getting stuck. After crossing the obstacle, the lifting driving device can drive the mop to descend to the cleaned surface, so that the cleaning work can continue. However, the two sets of driving devices need to occupy a large space, resulting in a very tight space inside the sweeping and mopping robot, which seriously affects the layout of components that also require space, such as dust boxes and / or water tanks. In this way, in order not to increase the external dimensions of the sweeping and mopping robot, these components can only be reduced in size, resulting in limited functions and poor product performance of the sweeping and mopping robot. In addition, the cost of two sets of driving devices is high, and two sets of circuit systems are required, so the manufacturing cost of the sweeping and mopping robot remains high. In addition, the two sets of driving devices will inevitably cause the sweeping and mopping robot to have a high failure rate, so the use cost of the sweeping and mopping robot is high and the product competitiveness is poor.

[0054] The embodiment of the utility model provides a driving device, which can be used to drive the cleaning member to rotate and can also be used to drive the cleaning member to rise and fall, so that the functions of cleaning and lifting can be taken into account, thereby improving the above-mentioned problem.

[0055] Specifically, Figure 1-4 As shown, the driving device of the embodiment of the present application can be applied to cleaning equipment, such as a cleaning robot. The driving device may include an output mechanism 200. The output mechanism 200 may include a fixing seat 300, a lifting frame 400, an output assembly 500, a first clutch assembly 600 and a second clutch assembly 700.

[0056] The fixed seat 300 can serve as the base of the output mechanism 200. The fixed seat 300 can be used to be connected to other components outside the output mechanism 200 to fix the output mechanism 200. In some embodiments, the drive device may further include a base 920. The fixed seat 300 may be fixed to the base 920 by any suitable means such as snap-on or connection with a connector. In this way, the fixed seat 300 can be connected to components outside the drive device through the base 920. In an embodiment in which the drive device is applied to a cleaning device, the base 920 may be used to be fixed to the main body of the cleaning device. The main body includes but is not limited to a shell or a frame. In this way, the fixed seat 300 is fixed relative to the main body of the cleaning device. The structure of the fixed seat 300 may be arbitrary, including but not limited to a base or a bracket.

[0057] like Figure 4 As shown, the fixed seat 300 and the lifting frame 400 can be threadedly connected. Specifically, the lifting frame 400 can be threadedly connected to the fixed seat 300 with the vertical axis PP as the center. The lifting frame 400 can rotate along the first circumferential direction A and the second circumferential direction B. The first circumferential direction A and the second circumferential direction B can be opposite. And, the first circumferential direction A and the second circumferential direction B can be around the vertical axis PP. Therefore, the first circumferential direction A and the second circumferential direction B can be two opposite rotation directions in the horizontal plane. Among them, the lifting frame 400 rises when rotating along the first circumferential direction A. And, the lifting frame 400 descends when rotating along the second circumferential direction B. The lifting direction of the lifting frame 400 can be parallel to the vertical axis PP.

[0058] The output assembly 500 can rotate around the vertical axis PP under the action of a driving force. The driving force can be provided in any suitable manner, such as manually or by the power assembly 100 described below. The output assembly 500 and the lifting frame 400 can be raised and lowered synchronously. The output assembly 500 and the lifting frame 400 can be raised and lowered synchronously in any suitable manner, such as one of them can be provided with a groove, and the other of them can be provided with a protrusion rotatable relative to the groove. One end of the output assembly 500 can be used to connect with a cleaning member or other component. The cleaning member includes but is not limited to a mop or a cleaning brush. The output assembly 500 can rotate around the vertical axis PP to drive the cleaning member to rotate. When the cleaning member contacts a cleaned surface such as a ground or a countertop, the cleaning member can rotate on the cleaned surface to clean the cleaned surface.

[0059] The first clutch assembly 600 is movably connected to the lifting frame 400 or the output assembly 500 between a first engagement position and a first separation position. The first clutch assembly 600 can be switched between the first engagement position and the first separation position by any suitable means such as mechanical contact or magnetic attraction. Figure 3-4 In the illustrated embodiment, the first clutch assembly 600 is movably coupled to the lifting frame 400 between a first engaged position and a first disengaged position. Figure 9-10 In the illustrated embodiment, the first clutch assembly 600 is movably connected to the output assembly 500 between a first engaged position and a first disengaged position. The first clutch assembly 600 may be movable in any manner, such as pivoting or translating. Figure 3-4 In the illustrated embodiment, the first clutch assembly 600 is pivotally connected to the lifting frame 400. Figure 9-10 In the illustrated embodiment, the first clutch assembly 600 is translationally coupled to the output assembly 500 .

[0060] When the first clutch assembly 600 is in the first engagement position, the lifting frame 400 and the output assembly 500 can be engaged, so as to be able to rotate synchronously along the first circumferential direction A around the vertical axis PP and rise relative to the fixing base 300. When the first clutch assembly 600 is in the first separation position, the lifting frame 400 and the output assembly 500 can be separated.

[0061] The second clutch assembly 700 is movably connected to the lifting frame 400 or the output assembly 500 between a second engagement position and a second separation position. The second clutch assembly 700 can be switched between the second engagement position and the second separation position by any suitable means such as mechanical contact or magnetic attraction. Figure 3-4 In the illustrated embodiment, the second clutch assembly 700 is movably coupled to the lifting frame 400 between a second engaged position and a second disengaged position. Figure 9-10 In the illustrated embodiment, the second clutch assembly 700 is movably connected to the output assembly 500 between a second engaged position and a second disengaged position. The second clutch assembly 700 may be movable in any manner, such as pivoting or translating. Figure 3-4 In the illustrated embodiment, the second clutch assembly 700 is pivotally connected to the lifting frame 400. Figure 9-10 In the illustrated embodiment, the second clutch assembly 700 is translationally coupled to the output assembly 500 .

[0062] When the second clutch assembly 700 is in the second engagement position, the lifting frame 400 and the output assembly 500 can be engaged, so as to be able to rotate synchronously along the second circumferential direction B around the vertical axis PP and descend relative to the fixing base 300. When the second clutch assembly 700 is in the second separation position, the lifting frame 400 and the output assembly 500 can be separated.

[0063] The above only describes Figure 9-10 The illustrated embodiments and Figure 3-4 The difference between the embodiments shown is that Figure 9-10 The illustrated embodiments and Figure 3-4 The same or similar components of the illustrated embodiments are denoted by the same reference numerals, and for the sake of brevity, these same or similar components will not be described in detail herein.

[0064] In actual application, when the output assembly 500 receives the driving force and rotates along the first circumferential direction A, and the first clutch assembly 600 is in the first engagement position, the lifting frame 400 and the output assembly 500 can be engaged to rotate synchronously along the first circumferential direction A. In this way, the lifting frame 400 can rise, thereby driving the output assembly 500 to rise synchronously. In this way, the output assembly 500 can drive the cleaning member connected thereto to rise. In this way, the driving device can be used to drive the cleaning member to rise for obstacle crossing work, or to lift the mop to achieve dry and wet separation during cleaning. When the first clutch assembly 600 moves to the first separation position, the lifting frame 400 and the output assembly 500 can be separated. Therefore, even if the output assembly 500 continues to rotate along the first circumferential direction A, the lifting frame 400 will not rotate along the first circumferential direction A, and thus will not continue to rise.

[0065] On the contrary, when the output assembly 500 receives the driving force and rotates along the second circumferential direction B, and the second clutch assembly 700 is in the second engagement position, the lifting frame 400 and the output assembly 500 can be engaged to rotate synchronously along the second circumferential direction B. In this way, the lifting frame 400 can descend, thereby driving the output assembly 500 to descend synchronously. In this way, the output assembly 500 can drive the cleaning member connected thereto to descend. In this way, the driving device can be used to drive the cleaning member to re-contact the cleaned surface after crossing the obstacle to resume the cleaning work. When the second clutch assembly 700 moves to the second separation position, the lifting frame 400 and the output assembly 500 can be separated. Therefore, even if the output assembly 500 continues to rotate along the second circumferential direction B, the lifting frame 400 will not rotate along the second circumferential direction B, and thus will not continue to descend. In this way, the driving device can be used to drive the cleaning member to continue to rotate on the cleaned surface, so that the cleaning work can be continued.

[0066] In summary, the driving device provided in the embodiment of the utility model can be used to drive the cleaning member to rotate and rise by rotating the output assembly 500 along the first circumferential direction A; and can be used to drive the cleaning member to rotate and descend by rotating the output assembly 500 along the second circumferential direction B. Therefore, the driving device can be used to drive the cleaning member to rotate to perform cleaning work, and can also be used to lift the cleaning member to perform obstacle work, or lift the mop to achieve dry and wet separation during cleaning. In this way, the driving device can take into account the functions of cleaning and lifting, so that it can replace the traditional rotary driving device and lifting driving device. When the driving device is applied to the cleaning equipment, the cleaning equipment can reduce a set of driving devices, thereby saving a lot of space for the layout of components such as dust boxes and / or water tanks. For example, the saved space can be used to increase the volume of dust boxes and / or water tanks to improve the product performance of the cleaning equipment. In addition, since a set of driving devices is saved, the cleaning equipment can also save a set of circuit systems, so its manufacturing cost can be greatly reduced. In addition, due to the reduction of components, the failure rate of the cleaning equipment can be reduced, the cost of use can be reduced, and the competitiveness of the product is better.

[0067] Exemplarily, when the output assembly 500 rotates along the first circumferential direction A, the first clutch assembly 600 is in the first engagement position, so as to be able to drive the lifting frame 400 to rise. Furthermore, when the lifting frame 400 rises to the upper limit position, the first clutch assembly 600 can be switched to the first separation position. When the output assembly 500 rotates along the second circumferential direction B, the second clutch assembly 700 is in the second engagement position, so as to be able to drive the lifting frame 400 to descend. Furthermore, when the lifting frame 400 descends to the lower limit position, the second clutch assembly 700 can be switched to the second separation position. In this way, the lifting frame 400 can be raised and lowered between the upper limit position and the lower limit position, thereby ensuring that the cleaning member is always in the expected height range.

[0068] Exemplarily, the driving device may include a first driving member. The first driving member may be disposed on at least one of the fixing seat 300, the output assembly 500, and the lifting frame 400. The first driving member may be used to apply a first force to the first clutch assembly 600 so that the first clutch assembly 600 can switch between the first engagement position and the first separation position. The first driving member includes but is not limited to a push member, a magnetic member, or an electromagnet, as long as the above functions can be achieved.

[0069] Exemplarily, the driving device may include a second driving member. The second driving member may be disposed on at least one of the fixing seat 300, the output assembly 500, and the lifting frame 400. The second driving member may be used to apply a second force to the second clutch assembly 700 so that the second clutch assembly 700 can switch between the second engagement position and the second separation position. The second driving member includes but is not limited to a push member, a magnetic member, or an electromagnet, as long as the above functions can be achieved.

[0070] For example, Figure 4 As shown, the fixing base 300 may include a side wall 323, a top wall 321, and a bottom wall 322. The side wall 323 may be connected between the top wall 321 and the bottom wall 322. The lifting frame 400 may be threadedly connected to the inner circumference of the side wall 323.

[0071] The top wall 321 can form a first driving member. In this way, when the lifting frame 400 rises to the upper limit position, the top wall 321 can abut against the first clutch assembly 600, so that the first clutch assembly 600 can be switched from the first engaged position to the first disengaged position. In this way, the top wall 321 of the fixing seat 300 can be used to switch the position of the first clutch assembly 600 and also limit the lifting frame 400.

[0072] The bottom wall 322 can form a second driving member. In this way, when the lifting frame 400 descends to the lower limit position, the bottom wall 322 can abut against the second clutch assembly 700, so that the second clutch assembly 700 can be switched from the second engagement position to the second separation position. In this way, the bottom wall 322 of the fixing seat 300 can be used to switch the position of the second clutch assembly 700 and also limit the lifting frame 400.

[0073] Exemplarily, the first driving member may include a first magnetic member (not shown in the figure). The first magnetic member may be disposed on the fixing seat 300. Moreover, the first magnetic member may be located at the upper limit position. When the lifting frame 400 rises to the upper limit position, the first magnetic member may attract the first clutch assembly 600 so that the first clutch assembly 600 may switch from the first engaged position to the first disengaged position. With such an arrangement, the structure of the first driving member is relatively simple, and the noise of the driving device is relatively low.

[0074] Exemplarily, the second driving member may include a second magnetic member (not shown in the figure). The second magnetic member may be arranged on the fixing seat 300. And, the second magnetic member may be located at the lower limit position. When the lifting frame 400 descends to the lower limit position, the second magnetic member may attract the second clutch assembly 700 so that the second clutch assembly 700 may switch from the second engaged position to the second disengaged position. With such an arrangement, the structure of the second driving member is relatively simple, and the noise of the driving device is relatively low.

[0075] Exemplarily, the first driving member may include a first electromagnet (not shown in the figure). The first electromagnet may be provided on one of the lifting frame 400 and the output assembly 500. The second driving member may include a second electromagnet (not shown in the figure). The second electromagnet may be provided on one of the lifting frame 400 and the output assembly 500.

[0076] During the process of the lifting frame 400 rising toward the upper limit position, the first electromagnet can be energized, so that the first clutch assembly 600 can be electrically attracted, so that the first clutch assembly 600 can be maintained in the first engagement position; and the second electromagnet can be de-energized, so that the second clutch assembly 700 can be cancelled from being electrically attracted, so that the second clutch assembly 700 can be in the second separation position. When the lifting frame 400 rises to the upper limit position, the first electromagnet can be de-energized, so that the first clutch assembly 600 can be cancelled from being electrically attracted, so that the first clutch assembly 600 can be switched to the first separation position. With such a configuration, the structure of the first driving member is relatively simple, and the noise of the driving device is relatively low.

[0077] During the process of the lifting frame 400 descending toward the lower limit position, the second electromagnet can be powered on, so that the second clutch assembly 700 can be electrically attracted, so that the second clutch assembly 700 can be maintained in the second engagement position; and the first electromagnet can be powered off, so that the first clutch assembly 600 can be cancelled from being electrically attracted, so that the first clutch assembly 600 can be in the first separation position. When the lifting frame 400 descends to the lower limit position, the second electromagnet can be powered off, so that the second clutch assembly 700 can be cancelled from being electrically attracted, so that the second clutch assembly 700 can be switched to the second separation position. With such a configuration, the structure of the second driving member is relatively simple, and the noise of the driving device is relatively low.

[0078] For example, Figure 4-8 As shown, the first clutch assembly 600 may include a first claw 610 and a first elastic member 620. The first claw 610 may be movably connected to one of the lifting frame 400 and the output assembly 500. The first elastic member 620 may be connected between the first claw 610 and one of the lifting frame 400 and the output assembly 500. Figure 3-4 In the illustrated embodiment, the first claw 610 is movably connected to the lifting frame 400. Figure 9-10 In the illustrated embodiment, the first claw 610 is movably connected to the output assembly 500. The first claw 610 can be movable in any manner, such as pivoting or translating. Figure 3-4 In the illustrated embodiment, the first claw 610 is pivotally connected to the lifting frame 400. Figure 9-10 In the illustrated embodiment, the first claw 610 is translatably connected to the output assembly 500. The first elastic member 620 includes, but is not limited to, a linear spring or a torsion spring. The other of the lifting frame 400 and the output assembly 500 may be provided with a first clamping slot 510. Figure 3-4 In the illustrated embodiment, the first card slot 510 may be disposed on the output assembly 500 .

[0079] The first elastic member 620 can be used to provide a first elastic force to the first claw 610. The first claw 610 can be inserted into the first slot 510 under the action of the first elastic force, so that it can engage with the first slot 510, so that the first clutch assembly 600 can be in the first engagement position. When the output assembly 500 is in the upper limit position, the first driving member and the first claw 610 can cooperate and resist the first elastic force, so that the position of the first claw 610 can be changed, and then the first claw 610 can be separated from the first slot 510, so that the first clutch assembly 600 can be in the first separation position. When the output assembly 500 drops from the upper limit position, the first driving member and the first claw 610 can lose the cooperation, so that they cannot resist the first elastic force, and the first elastic member 620 can release the first elastic potential energy, so that the first claw 610 can be switched to the position engaged with the first slot 510, so that the output assembly 500 can rise. In this way, the structure of the first clutch assembly 600 is relatively simple, and it is convenient to switch between the first engagement position and the first separation position. For example, Figure 4-8 As shown, the second clutch assembly 700 may include a second claw 710 and a second elastic member 720. The second claw 710 may be movably connected to one of the lifting frame 400 and the output assembly 500. The second elastic member 720 may be connected between the second claw 710 and one of the lifting frame 400 and the output assembly 500. Figure 3-4 In the illustrated embodiment, the second claw 710 is movably connected to the lifting frame 400. Figure 9-10 In the illustrated embodiment, the second claw 710 is movably connected to the output assembly 500. The second claw 710 can be movable in any manner, such as pivoting or translating. Figure 3-4 In the illustrated embodiment, the second claw 710 is pivotally connected to the lifting frame 400. Figure 9-10 In the illustrated embodiment, the second claw 710 is translatably connected to the output assembly 500. The second elastic member 720 includes, but is not limited to, a linear spring or a torsion spring. The other of the lifting frame 400 and the output assembly 500 may be provided with a second clamping slot 520. Figure 3-4In the illustrated embodiment, the second clamping groove 520 may be provided on the output assembly 500. The second elastic member 720 may be used to provide a second elastic force to the second clamping claw 710. The second clamping claw 710 may be inserted into the second clamping groove 520 under the action of the second elastic force, so that it may engage with the second clamping groove 520, so that the second clutch assembly 700 may be in the second engagement position. When the output assembly 500 is in the lower limit position, the second driving member and the second clamping claw 710 may cooperate and resist the second elastic force, so that the position of the second clamping claw 710 may be changed, and then the second clamping claw 710 may be separated from the second clamping groove 520, so that the second clutch assembly 700 may be in the second separation position. When the output assembly 500 rises from the lower limit position, the second driving member and the second clamping claw 710 may lose cooperation, so that it is unable to resist the second elastic force, and the second elastic member 720 may release the second elastic potential energy, so that the second clamping claw 710 may be switched to the position engaged with the second clamping groove 520, so that the output assembly 500 may descend. With such arrangement, the structure of the second clutch assembly 700 is relatively simple, and can be easily switched between the second engaged position and the second disengaged position.

[0080] For example, Figure 4-7 As shown, the first slot 510 can be recessed downward. The "downward" is relative to the driving device in Figure 4-7. In terms of the placement state shown. In addition, the first slot 510 has a first slot side wall 511, a second slot side wall 512 and a first slot bottom wall 513. The first slot side wall 511 and the second slot side wall 512 can be arranged opposite to each other along the first circumferential direction A. The first slot side wall 511 can extend upwardly and obliquely from the first slot bottom wall 513 along the first circumferential direction A. Wherein: when the lifting frame 400 is in the non-upper limit position and the output assembly 500 rotates along the first circumferential direction A, the second slot side wall 512 can abut against the first claw 610. In this way, the first clutch assembly 600 can be in the first engagement position. In this way, the second slot side wall 512 can drive the lifting frame 400 to rotate along the first circumferential direction A through the first claw 610, and the lifting frame 400 can rise. When the lifting frame 400 is in the non-upper limit position and the output assembly 500 rotates along the second circumferential direction B, the first claw 610 can slide out of the first slot 510 along the inclined first slot side wall 511. As the output assembly 500 rotates along the second circumferential direction B, the first claw 610 can slide out of the first slot 510 along the first slot side wall 511, and then can slide back into the first slot 510 from the side of the second slot side wall 512, and then continue to slide out of the first slot 510 along the first slot side wall 511, and repeat this process. In this way, when the output assembly 500 rotates along the second circumferential direction B, the output assembly 500 and the lifting frame 400 are not relatively fixed in the circumferential direction, so in this process, the output assembly 500 will not drive the lifting frame 400 to rise. When the lifting frame 400 is at the upper limit position, the first claw 610 can be disengaged from the first slot 510. In this way, whether the output assembly 500 rotates along the first circumferential direction A or the second circumferential direction B, it will not drive the lifting frame 400 to rise. In this way, the structure of the first clutch assembly 600 is relatively simple, and the clutch effect is better.

[0081] For example, Figure 4-7 As shown, the second slot 520 can be recessed upward. The "upward" is relative to the driving device in Figure 4-7. In terms of the placement state shown. In addition, the second slot 520 has a third slot side wall 521, a fourth slot side wall 522, and a second slot bottom wall 523. The third slot side wall 521 and the fourth slot side wall 522 can be arranged opposite to each other along the second circumferential direction B. The third slot side wall 521 can extend downwardly from the second slot bottom wall 523 along the second circumferential direction B. Wherein: when the lifting frame 400 is in a non-lower limit position and the output assembly 500 rotates along the second circumferential direction B, the fourth slot side wall 522 can abut against the second claw 710. In this way, the first clutch assembly 600 can be in the first engagement position. In this way, the fourth slot side wall 522 can drive the lifting frame 400 to rotate along the second circumferential direction B through the second claw 710, and the lifting frame 400 can descend. When the lifting frame 400 is in a non-lower limit position and the output assembly 500 rotates along the first circumferential direction A, the second claw 710 can slide out of the second slot 520 along the inclined third slot side wall 521. As the output assembly 500 rotates along the first circumferential direction A, the second claw 710 can slide out of the second slot 520 along the third slot side wall 521, and then can slide back into the second slot 520 from the side of the fourth slot side wall 522, and then continue to slide out of the second slot 520 along the third slot side wall 521, and repeat this process. In this way, when the output assembly 500 rotates along the first circumferential direction A, the output assembly 500 and the lifting frame 400 are not relatively fixed in the circumferential direction, so in this process, the output assembly 500 will not drive the lifting frame 400 to descend. When the lifting frame 400 is at the lower limit position, the second claw 710 can be disengaged from the second slot 520. In this way, whether the output assembly 500 rotates along the first circumferential direction A or the second circumferential direction B, it will not drive the lifting frame 400 to descend. In this way, the structure of the second clutch assembly 700 is relatively simple, and the clutch effect is better.

[0082] For example, Figure 4-8 As shown, the middle portion of the first claw 610 is pivotally connected to one of the lifting frame 400 and the output assembly 500. In the illustrated embodiment, a first pivot 611 may be provided at the middle portion of the first claw 610. The first pivot 611 may be inserted into a pivot hole on the lifting frame 400. In this way, the middle portion of the first claw 610 is pivotally connected to the lifting frame 400. The first elastic member 620 may apply a first elastic force to one end of the first claw 610. The other end of the first claw 610 may engage with the first slot 510. In this way, when the output assembly 500 rises to the upper limit position, the fixing seat 300 may abut against one end of the first claw 610, thereby causing the other end of the first claw 610 to tilt up and then be disengaged from the first slot 510.

[0083] For example, Figure 4-8As shown, the middle portion of the second claw 710 is pivotally connected to one of the lifting frame 400 and the output assembly 500. In the illustrated embodiment, a second pivot 711 may be provided at the middle portion of the second claw 710. The second pivot 711 may be inserted into a pivot hole on the lifting frame 400. In this way, the middle portion of the second claw 710 is pivotally connected to the lifting frame 400. The second elastic member 720 may apply a second elastic force to one end of the second claw 710. The other end of the second claw 710 may engage with the second slot 520. In this way, when the output assembly 500 is lowered to the lower limit position, the fixing seat 300 may abut against one end of the second claw 710, thereby causing the other end of the second claw 710 to tilt up and then disengage from the second slot 520.

[0084] It should be noted that in the embodiment of the present application, the middle of the first claw 610 does not specifically refer to the structural center of the first claw 610, but actually refers to the middle between the two ends of the first claw 610. Similarly, the middle of the second claw 710 does not specifically refer to the structural center of the second claw 710, but actually refers to the middle between the two ends of the second claw 710.

[0085] For example, Figure 4-8 As shown, the first card slot 510 may include a plurality of first card slots 510. The plurality of first card slots 510 may be arranged at intervals along the first circumferential direction A. In this way, when the output assembly 500 rotates along the first circumferential direction A, the first claw 610 may be engaged with the first card slot 510 more quickly, thereby improving the response speed of the output assembly 500 rising.

[0086] For example, Figure 4-8 As shown, the second clamping slot 520 may include a plurality of second clamping slots 520. The plurality of second clamping slots 520 may be arranged at intervals along the second circumferential direction B. In this arrangement, when the output assembly 500 rotates along the second circumferential direction B, the second claw 710 may be engaged with the second clamping slot 520 more quickly, thereby improving the response speed of the output assembly 500 descending.

[0087] For example, Figure 4 As shown, when the lifting frame 400 rises to the upper limit position, the top wall 321 of the fixing seat 300 can abut against the first claw 610 and resist the first elastic force, so that the first clutch assembly 600 can be in the first separation position. In this way, the top wall 321 of the fixing seat 300 can be used to switch the position of the first clutch assembly 600 and also limit the lifting frame 400.

[0088] For example, Figure 4As shown, when the lifting frame 400 descends to the lower limit position, the bottom wall 322 of the fixing seat 300 can abut against the second claw 710 and resist the second elastic force, so that the second clutch assembly 700 can be in the second separation position. In this way, the bottom wall 322 of the fixing seat 300 can be used to switch the position of the second clutch assembly 700 and also limit the lifting frame 400.

[0089] For example, Figure 4 As shown, the lifting frame 400 can be arranged in the fixed seat 300. An internal thread 310 can be arranged on the inner peripheral wall of the fixed seat 300 (i.e., the inner peripheral side of the above-mentioned side wall 323). An external thread 410 can be arranged on the outer peripheral wall of the lifting frame 400. The internal thread 310 can be threadedly connected to the external thread 410. In this way, the fixed seat 300 can serve as a shell of the lifting frame 400, so as to protect the lifting frame 400. In addition, the fixed seat 300 can also guide the lifting frame 400 to improve the stability of the lifting of the lifting frame 400. One end of the output component 500 can extend outside the fixed seat 300 for connection with a cleaning member or other components. The other end of the output component 500 can be inserted into the fixed seat 300. In addition, the lifting frame 400 can be sleeved on the other end of the output component 500.

[0090] For example, Figure 4 As shown, the output mechanism 200 may further include a first bearing 810. The first bearing 810 may be connected between the lifting frame 400 and the other end of the output assembly 500. By providing the first bearing 810, the lifting frame 400 and the output assembly 500 may be lifted and lowered synchronously and may rotate relative to each other. Therefore, the structure of the driving device is relatively simple and easy to assemble.

[0091] For example, Figure 4 As shown, the output mechanism 200 may further include a second bearing 820. The second bearing 820 may be connected between the fixing seat 300 and the output assembly 500. The second bearing 820 may support the output assembly 500, thereby ensuring that the rotation stability of the output assembly 500 is high, and further improving the stability of the output assembly 500 in lifting and lowering.

[0092] For example, Figure 1-4As shown, the drive device may also include a power assembly 100. The power assembly 100 may be used to provide driving force. In an embodiment where the drive device includes a base 920, the power assembly 100 may also be fixed to the base 920. The output assembly 500 may be directly or indirectly connected to the drive shaft of the power assembly 100. The power assembly 100 may output driving force through the drive shaft to drive the output assembly 500 to rotate around the vertical axis PP. The power assembly 100 includes but is not limited to a motor, a rotary cylinder or any other suitable power assembly. In some embodiments, the power assembly 100 may be used to provide torque. The output assembly 500 may be used to receive torque and rotate around the vertical axis PP. With such a configuration, the drive device has a high degree of automation, thereby improving the user experience.

[0093] For example, Figure 1-8As shown, the power assembly 100 may include a driving motor 110 and a driving gear 120. The driving shaft of the driving motor 110 may provide driving force. The driving gear 120 may be sleeved on the driving shaft of the driving motor 110. The output assembly 500 may include an output shaft 530 and a lifting connection member 550. The lifting connection member 550 may be sleeved on the output shaft 530. The output shaft 530 may also be sleeved with an output gear 540. The driving gear 120 may be meshed with the output gear 540. In this way, the driving shaft of the driving motor 110 may drive the driving gear 120 to rotate, thereby driving the output gear 540 to rotate, and then driving the output shaft 530 and the lifting connection member 550 to rotate synchronously. One end and the other end of the output assembly 500 may be the two ends of the output shaft 530, respectively. That is, one end of the output shaft 530 may be used to connect the cleaning member. When the first clutch assembly 600 is in the first engagement position, the lifting frame 400 and the lifting connection member 550 may be engaged. The output shaft 530 can rotate along the first circumferential direction A, thereby driving the lifting connection 550 and the lifting frame 400 to rotate along the first circumferential direction A. In this way, the lifting frame 400 can rise, thereby driving the output shaft 530 and the lifting connection 550 to rise. When the first clutch assembly 600 is in the first separation position, the lifting frame 400 and the lifting connection 550 can be separated. When the second clutch assembly 700 is in the second engagement position, the lifting frame 400 and the lifting connection 550 can be engaged. The output shaft 530 can rotate along the second circumferential direction B, thereby driving the lifting connection 550 and the lifting frame 400 to rotate along the second circumferential direction B. In this way, the lifting frame 400 can descend, thereby driving the output shaft 530 and the lifting connection 550 to descend. Therefore, the output shaft 530 can have a certain gap with the output gear 540 to facilitate the output shaft 530 to rise and fall relative to the output gear 540. When the second clutch assembly 700 is in the second separation position, the lifting frame 400 and the lifting connection member 550 can be separated. That is to say, the first clutch assembly 600 and the second clutch assembly 700 realize the engagement and separation of the lifting frame 400 and the output assembly 500 by cooperating and separating with the lifting connection member 550 on the output assembly 500. By setting the output shaft 530 and sleeve the lifting connection member 550 on the output shaft 530, the output shaft 530 and the lifting connection member 550 can be formed separately and assembled and matched, which is conducive to reducing the difficulty of production. The cleaning member in the prior art is usually directly connected to the power assembly through an output shaft, and this embodiment can be directly sleeved on the output shaft 530 by the lifting connection member 550, so that there is no need to change the structure of the existing cleaning member, so the driving device of the utility model can directly replace the existing device. In addition, by setting the lifting connection member 550, it is easy to achieve engagement and separation with the first clutch assembly 600 and the second clutch assembly 700.

[0094] For example, Figure 4-8As shown, the lifting connection member 550 may include an ascending connection member 551 and a descending connection member 552. The ascending connection member 551 and the descending connection member 552 may be arranged at intervals along the vertical axis PP. The ascending connection member 551 may be located above the descending connection member 552. The first clamping groove 510 may be provided in the ascending connection member 551, and the second clamping groove 520 may be provided in the descending connection member 552.

[0095] When the first clutch assembly 600 is in the first engagement position, the lifting frame 400 and the ascending connection member 551 can be engaged. When the first clutch assembly 600 is in the first separation position, the lifting frame 400 and the ascending connection member 551 can be separated. When the second clutch assembly 700 is in the second engagement position, the lifting frame 400 and the descending connection member 552 can be engaged. When the second clutch assembly 700 is in the second separation position, the lifting frame 400 and the descending connection member 552 can be separated. With such a configuration, the lifting connection member 550 can be manufactured in separate parts, thereby reducing the difficulty of manufacturing. For example, as Figure 5-6 As shown, the cross section of the output shaft 530 may be D-shaped. It is understandable that the output gear 540 may be provided with a D-shaped through hole adapted to the output shaft 530. Since the D-shape has a notch, the output shaft 530 and the output gear 540 may rotate synchronously to ensure that the output assembly 500 can always receive the torque of the power assembly 100, thereby avoiding energy waste.

[0096] For example, Figure 1-2 As shown, the drive device may further include a transmission assembly 910. The transmission assembly 910 may be connected between the power assembly 100 and the output assembly 500. The transmission assembly 910 includes but is not limited to a chain transmission assembly, a belt transmission assembly or a worm gear transmission assembly. In the embodiment shown in the figure, the transmission assembly 910 may include a gear transmission assembly. The gear transmission assembly may be engaged between the drive gear 120 and the output gear 540. By setting the transmission assembly 910, the power assembly 100 and the output assembly 500 can achieve long-distance transmission, thereby improving the degree of freedom of the layout of the two. In addition, the transmission assembly 910 can change parameters such as the transmission ratio and / or the transmission direction, and the use effect of the drive device can better meet the user's use requirements. And, by improving the setting of the transmission assembly 910, it is convenient for the power assembly 100 to drive multiple output mechanisms 200 at the same time.

[0097] For example, Figure 1-2 As shown, the output mechanism 200 may include multiple, for example two, three or more. Multiple output mechanisms 200 may be connected to the power assembly 100 via a transmission assembly 910 respectively. One end of the output assembly 500 of each output mechanism 200 may be used to be connected to a cleaning member.

[0102] The first clutch assembly 600 can be movably disposed between the lifting frame 400 and the output assembly 500. In addition, the first clutch assembly 600 can be switched between a first engagement position and a first separation position. When the first clutch assembly 600 is in the first engagement position, the lifting frame 400 can be engaged with the output assembly 500. When the first clutch assembly 600 is in the first separation position, the lifting frame 400 can be separated from the output assembly 500.

[0103] The second clutch assembly 700 can be movably disposed between the lifting frame 400 and the output assembly 500. In addition, the second clutch assembly 700 can be switched between a second engagement position and a second separation position. When the second clutch assembly 700 is in the second engagement position, the lifting frame 400 can be engaged with the output assembly 500. When the second clutch assembly 700 is in the second separation position, the lifting frame 400 can be separated from the output assembly 500.

[0104] When the first clutch assembly 600 is in the first engagement position and the output assembly 500 rotates along the first circumferential direction A, the output assembly 500 and the lifting frame 400 can rise together relative to the fixed seat 300. When the second clutch assembly 700 is in the second engagement position and the output assembly 500 rotates along the second circumferential direction B, the output assembly 500 and the lifting frame 400 can descend together relative to the fixed seat 300. The first circumferential direction A and the second circumferential direction B can be opposite.
