[0051] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0052] Reference below Figure 1-Figure 9 The cleaning device 100 according to an embodiment of the utility model is described, which can selectively drive the cleaning component 20 to perform overall translation and ascent work or overall extension work in the lateral direction or overall extension work in the lateral direction and overall translation and ascent work at the same time according to different working environments, so that the cleaning component 20 can achieve the effect of adapting to the current working environment.

[0053] Combination Figure 1-Figure 9 As shown, the cleaning device 100 according to the first embodiment of the utility model includes a body 10, a cleaning assembly 20, a lifting mechanism 30 and a translation mechanism 40. The body 10 is mainly used as a structural member for the inner and outer contours of the cleaning device 100. The cleaning assembly 20 is mainly used as a structural member for performing cleaning work. The lifting mechanism 30 can drive the cleaning assembly 20 to translate and rise as a whole. The translation mechanism 40 can drive the cleaning assembly 20 to translate and extend as a whole in the lateral direction (that is, the left and right direction).

[0054] Specifically, the cleaning assembly 20 is arranged below the machine body 10, the lifting mechanism 30 is in transmission connection with the cleaning assembly 20 to selectively drive the cleaning assembly 20 to rise, and the translation mechanism 40 is arranged on the machine body 10 to drive the cleaning assembly 20 to extend along the lateral direction of the cleaning device 100 under the drive of the translation mechanism 40. The lifting mechanism 30 and the translation mechanism 40 can be arranged on the same base, so that the structural arrangement in the machine body can be simplified. Of course, the lifting mechanism 30 and the translation mechanism 40 can also be arranged independently of each other.

[0055] In addition, the cleaning component 20 is arranged below the body 10, so that the cleaning component 20 can directly contact the cleaning surface; the translation mechanism 40 is arranged on the body 10, and the translation mechanism 40 and the lifting mechanism 30 are both transmission connected with the cleaning component 20, so that the lifting mechanism 30 can selectively drive the cleaning component 20 below the body 10 to rise, and can also facilitate the translation mechanism 40 to selectively drive the cleaning component 20 to extend along the lateral direction of the cleaning equipment 100.

[0056] For example, when the cleaning component 20 is performing cleaning work (such as mopping or sweeping the floor), when it encounters special working environments such as carpets, obstacles, etc., the lifting mechanism 30 can drive the cleaning component 20 to translate and rise as a whole to adapt to the current working environment (at this time, the cleaning component 20 is not in contact with the cleaning surface); for another example, when the cleaning component 20 passes through a special working environment and encounters a conventional working environment such as a floor, the lifting mechanism 30 can drive the cleaning component 20 to translate and descend as a whole until the cleaning component 20 contacts the cleaning surface, thereby improving the adaptability of the cleaning device 100 in different working environments, and further improving the cleaning work efficiency of the cleaning device 100.

[0057] For another example, when the cleaning component 20 is performing cleaning work (such as mopping or sweeping the floor), when it encounters a special working environment such as an obstacle, the translation mechanism 40 can drive the cleaning component 20 to extend as a whole in the lateral direction to adapt to the current working environment (at this time, the cleaning component 20 bypasses the obstacle on the cleaning work surface and translates to the side of the obstacle); for another example, when the cleaning component 20 passes through a special working environment and encounters a conventional working environment such as a floor, the translation mechanism 40 can drive the cleaning component 20 to retract as a whole in the lateral direction until the cleaning component 20 returns to the initial position (that is, the relative position of the cleaning component 20 and the body 10 before extension), thereby improving the adaptability of the cleaning device 100 in different working environments, and further improving the cleaning work efficiency of the cleaning device 100.

[0058] For another example, when the cleaning device 100 is mopping the floor along the edge of a wall, the translation mechanism 40 drives the cleaning component 20 to extend out of the edge of the body 10 in the lateral direction (i.e., extend outward). When the cleaning device 100 leaves the edge scene, the translation mechanism 40 drives the cleaning component 20 to retract into the edge of the body 10 (i.e., retract inward). This can overcome the problem that the cleaning component 20 cannot clean along the wall due to the limitation of the outer shell of the body 10 (the cleaning component 20 is in a fixed position at this time), thereby improving the cleaning efficiency of the cleaning device 100.

[0059] For another example, when the cleaning device 100 is mopping the floor along the edge of a wall (and encounters obstacles on the cleaning surface at the same time), the cleaning assembly 20 is driven by the lifting mechanism 30 to rise as a whole and is also driven by the translation mechanism 40 to extend as a whole in the lateral direction.

[0060] Of course, in the extended state or the retracted state, and in the lateral direction, the edge of the cleaning assembly 20 can extend beyond the edge of the machine body 10, but the dimension of the excess in the retracted state is smaller than the dimension of the excess in the extended state. The cleaning assembly 20 can extend from any side (in the lateral direction) of the machine body 10. Since the machine body 10 is used to move on the right, it is preferably extended from the right side.

[0061] The cleaning assembly 20 uses a crawler-type cleaning element. Compared with a traditional roller brush that can only increase the cleaning effect by increasing the number of bristles, the crawler-type cleaning element can achieve cleaning needs in different scenarios by changing the pressure of the brush head. For example, when cleaning a hard floor, the pressure of the brush head can be increased to increase the strength of the bristles, thereby achieving a faster and more thorough cleaning effect.

[0062] Therefore, by setting up the cleaning device 100, it can be enabled to selectively drive the cleaning component 20 to perform overall translation and ascent work or overall extension work in the lateral direction or overall extension work in the lateral direction and overall translation and ascent work at the same time according to different working environments, so that the cleaning component 20 can achieve the effect of adapting to the current working environment, thereby improving the cleaning work efficiency of the cleaning device 100.

[0063] According to some optional embodiments of the present invention, combined with Figure 1 , Figure 2 , Figure 6 , Figure 7 and Fig. 9 As shown, the cleaning assembly 20 includes a first base 21 and a track brush 22 , the lifting mechanism 30 is transmission-connected to the first base 21 , and the track brush 22 is disposed on the first base 21 .

[0064] Specifically, the track brush 22 is arranged below the first base 21, so that the track brush 22 can directly contact the surface to be cleaned, and the first base 21 can also form a certain protection and fixing effect on the track brush 22; and the lifting mechanism 30 is transmission-connected with the first base 21 below the body 10, so that the lifting mechanism 30 can indirectly achieve the effect of driving the track brush 22 to rise by driving the first base 21 to rise, thereby improving the design rationality and scientificity of the cleaning component 20.

[0065] According to some optional embodiments of the present invention, combined with Figure 4 , Figure 7-Figure 9 As shown, the translation mechanism 40 includes a translation drive member 41, a second base 42 and a translation transmission assembly 43. The second base 42 is connected to the cleaning assembly 20, one end of the translation transmission assembly 43 is connected to the translation drive member 41, and the other end of the translation transmission assembly 43 is connected to the second base 42. The translation drive member 41 selectively drives the second base 42 to extend along the lateral direction of the cleaning device 100 through the translation transmission assembly 43.

[0066] According to some optional embodiments of the present invention, the lifting mechanism 30 may be disposed on the second base 42 .

[0067] In detail, the two ends of the translation transmission assembly 43 are respectively connected to the translation drive member 41 and the second base 42, and the translation drive member 41 can indirectly transmit the driving force to the second base 42 through the translation transmission assembly 43, so as to achieve the effect of driving the second base 42, the lifting mechanism 30 and the cleaning assembly 20 to extend in the lateral direction as a whole, thereby improving the scientificity and design rationality of the translation mechanism 40. For example, the translation drive member 41 can be a motor, but is not limited thereto, so that the second base 42, the lifting mechanism 30 and the cleaning assembly 20 can be extended and retracted in the lateral direction respectively by the forward and reverse rotation of the motor.

[0068] Specifically, combined Figure 4 , Figure 6-Figure 9 As shown, the translation transmission assembly 43 includes a first transmission member 431 and a second transmission member 432 . The first transmission member 431 is disposed on the translation driving member 41 , and the second transmission member 432 is disposed on the second base 42 . The first transmission member 431 and the second transmission member 432 cooperate in transmission.

[0069] Among them, the translation drive member 41 is transmission connected to the first transmission member 431, and the first transmission member 431 is transmission connected to the second transmission member 432 on the second base 42, so that the translation drive member 41 can indirectly transmit the driving force to the second base 42 (because the lifting mechanism 30 is arranged on the second base 42 and the second base 42 is also connected to the cleaning component 20), thereby achieving the effect of the second base 42, the lifting mechanism 30 and the cleaning component 20 being translated as a whole along the lateral direction.

[0070] Optionally, the first transmission member 431 is a lead screw, and the second transmission member 432 is a nut, and the nut is threadedly matched with the lead screw. The structure of the lead screw and nut transmission matching is to use the principle of the inclined plane, and the inclined plane is curled and deformed to form a thread. In this way, the rotational motion of the lead screw can be converted into the translational motion of the nut (the nut translates one pitch for each rotation of the lead screw), thereby achieving the effect of the second base 42, the lifting mechanism 30 and the cleaning assembly 20 being translated as a whole in the lateral direction.

[0071] In addition, the thread can better withstand the load force from the axial direction, and the thread is self-locking, which can ensure that the nut can smoothly and stably drive the second base 42 to move in the lateral direction as the screw rotates, and can also avoid the problem of the second base 42 in the extended state undergoing unexpected inward movement.

[0072] Alternatively, the first transmission member 431 is a gear, and the second transmission member 432 is a rack, and the gear is meshed with the rack. The gear-rack meshing transmission can convert the rotational motion of the gear into the translational motion of the rack, thereby achieving the effect of overall translation of the second base 42 in the lateral direction. In addition, the gear-rack transmission has the characteristics of large power transmission, long service life, stable operation and high reliability, which can improve the movement efficiency of the second base 42 in the overall translation process in the lateral direction.

[0073] Specifically, the lifting mechanism 30 and the translation mechanism 40 are arranged in the machine body 10, and the machine body 10 is provided with a slide groove 11; the cleaning component 20 is provided with a connecting portion 23, and the connecting portion 23 is connected to the lifting mechanism 30 after passing through the slide groove 11. Among them, since the lifting mechanism 30 and the cleaning component 20 are respectively located on the upper and lower sides of the machine body 10, after the slide groove 11 is provided in the machine body 10, it is convenient for the connecting portion 23 on the cleaning component 20 to directly pass through the slide groove 11 and be transmission-connected with the lifting mechanism 30 above, so that the transmission connection path between the lifting mechanism 30 and the cleaning component 20 can be simplified and shortened, thereby improving the working efficiency of the lifting mechanism 30 driving the cleaning component 20 to rise.

[0074] Furthermore, combined with Figure 6-Figure 8 As shown, the machine body 10 includes a bottom shell 12, the cleaning assembly 20 is arranged below the bottom shell 12, the translation mechanism 40 and the lifting mechanism 30 are arranged above the bottom shell 12, and the bottom shell 12 is provided with a slide 11. Among them, since the translation mechanism 40 and the cleaning assembly 20 are respectively located at the upper and lower sides of the machine body 10, after the machine body 10 is provided with the slide 11, it is convenient for the connection part 23 on the cleaning assembly 20 to directly pass through the slide 11 and then be transmission-connected with the translation mechanism 40 above, so that the transmission connection path between the translation mechanism 40 and the first base 21 can be simplified and shortened; and the slide 11 extends in the transverse direction, so that the connection part 23 also has a certain transverse sliding range, thereby improving the working efficiency of the translation mechanism 40 driving the cleaning assembly 20 to translate as a whole in the transverse direction.

[0075] Specifically, combined Figure 7 and Figure 8 As shown, the bottom shell 12 is provided with a first guide portion 121, and the second base 42 is provided with a second guide portion 422, and the second guide portion 422 is guided and matched with the first guide portion 121 in the length direction of the slide slot 11. The first guide portion 121 on the bottom shell 12 is guided and matched with the second guide portion 422 on the second base 42 in the length direction (that is, the transverse direction) of the slide slot 11, so that the second base 42 can be translated according to the specified sliding cooperation path, thereby avoiding the problem of the second base 42 shaking during the translation process, and then ensuring the movement stability of the cleaning component 20 in the translation action along the transverse direction.

[0076] Further, one of the first guide portion 121 and the second guide portion 422 is configured as a guide rod and the other is configured as a guide head, the guide head is provided with a guide hole, and the guide rod is provided with the guide hole. For example, the first guide portion 121 is configured as a guide rod (the guide rod extends in the transverse direction), the second guide portion 422 is configured as a guide head, the guide rod is provided with a guide hole in the guide head, and the guide rod guides the movement path of the guide head, so that the guide head can slide along the specified extension direction of the guide rod, thereby improving the movement stability and smoothness of the cleaning assembly 20 in the transverse direction.

[0077] Specifically, the maximum extension of the cleaning assembly 20 relative to the machine body 10 in the lateral direction does not exceed the length of the slide slot 11. In this way, the extension size of the cleaning assembly 20 can be limited, avoiding the risk of the cleaning assembly 20 being too large and causing the related electronic components to be easily damaged by pulling, thereby ensuring the working stability of the cleaning assembly 20 during the cleaning process.

[0078] In detail, the lifting mechanism 30 is arranged on the second base 42. The second base 42 and the cleaning assembly 20 are arranged above and below the bottom shell 12, respectively, and the lifting mechanism 30 is arranged on the second base 42, so that the lifting mechanism 30 can be further protected and fixed, and the lifting mechanism 30 can be easily disassembled and installed. The cleaning assembly 20 below the bottom shell 12 is connected to the connecting member 323 through its own connecting part 23 after passing through the second base 42, so that the cleaning assembly 20 and the lifting mechanism 30 can smoothly form a connection relationship, so that the lifting mechanism 30 can drive the cleaning assembly 20 to perform an ascending action.

[0079] Furthermore, combined with Figure 3 and Figure 6 As shown, the lifting mechanism 30 includes a lifting drive member 31 and a lifting transmission assembly 32. The lifting drive member 31 is arranged on the second base 42. One end of the lifting transmission assembly 32 is connected to the lifting drive member 31, and the other end of the lifting transmission assembly 32 is connected to the cleaning assembly 20. The lifting drive member 31 selectively drives the cleaning assembly 20 to rise through the lifting transmission assembly 32.

[0080] In detail, the two ends of the lifting transmission assembly 32 are respectively connected to the lifting drive member 31 and the cleaning assembly 20, and the lifting drive member 31 can transmit the driving force to the cleaning assembly 20 through the lifting transmission assembly 32, so as to achieve the effect of driving the cleaning assembly 20 to rise, thereby improving the scientificity and design rationality of the lifting mechanism 30. For example, the lifting drive member 31 can be a motor, but is not limited thereto, so that the lifting effect of the cleaning assembly 20 can be achieved respectively by the forward and reverse rotation of the motor.

[0081] Specifically, combined Figure 4As shown, the lifting transmission assembly 32 includes a spool 321 and a pull wire 322, the spool 321 is connected to the lifting drive 31, one end of the pull wire 322 is connected to the spool 321, and the other end of the pull wire 322 is connected to the cleaning assembly 20. The spool 321 is synchronously connected to the lifting drive 31, and the two ends of the pull wire 322 are respectively connected to the spool 321 and the cleaning assembly 20, so that the lifting drive 31 can drive the spool 321 to rotate to wind the pull wire 322, thereby achieving the effect of shortening the height distance between the cleaning assembly 20 and the machine body 10, thereby achieving the lifting effect of the cleaning assembly 20.

[0082] Furthermore, combined with Figure 5-Figure 8 As shown, the lifting transmission assembly 32 also includes a connecting member 323 , which is disposed above the second base 42 and connected to the cleaning assembly 20 , and the other end of the pull wire 322 is connected to the connecting member 323 .

[0083] Among them, the connecting piece 323 above the second base 42 is connected to the cleaning component 20, and the connecting piece 323, the second base 42 and the cleaning component 20 form a whole, and the other end of the pull wire 322 is connected to the connecting piece 323, so that the pull wire 322 can form an indirect connection relationship with the cleaning component 20, thereby achieving the effect of driving the cleaning component 20 to rise stably; and it can also avoid the need for the pull wire 322 to pass through or bypass the body 10 to connect to the cleaning component 20, which can reduce the layout route of the pull wire 322, thereby reducing the risk of wear and tear that the pull wire 322 may suffer, thereby improving the stability of the lifting mechanism 30 driving the cleaning component 20 to rise.

[0084] For example, if there is one connecting member 323, the connecting member 323 can be set close to the central axis of the body 10; if there are two connecting members 323, they can be spaced apart and close to the two ends of the body 10; of course, the position of the connecting member 323 can be adaptively adjusted according to its number, so that the connecting member 323 can smoothly drive the cleaning component 20 to perform lifting and lowering movements.

[0085] Specifically, there are multiple connecting members 323, which are spaced apart above the second base 42, and all of the multiple connecting members 323 are connected to the cleaning assembly 20; there are multiple pull wires 322, one end of each of the pull wires 322 is connected to the spool 321, and the other ends of the pull wires 322 are connected to the multiple connecting members 323 one by one.

[0086] Among them, multiple connecting parts 323 located above the second base 42 and arranged at intervals are all connected to the cleaning component 20, and the two ends of the multiple pull wires 322 are also correspondingly connected to the spool 321 and the multiple connecting parts 323. In this way, the force transmission path and force transmission size of the lifting drive 31 for the cleaning component 20 during the rising process can be increased, thereby improving the movement smoothness and responsiveness of the cleaning component 20 during the rising process.

[0087] Furthermore, combined with Figure 3 and Figure 4 As shown, the cleaning assembly 20 is provided with a plurality of connecting parts 23 , each connecting part 23 is connected to at least two connecting parts 23 , and the other end of the pull wire 322 is connected to the center of the corresponding connecting part 23 .

[0088] Among them, each connecting member 323 is connected to at least two connecting parts 23 on the cleaning component 20, so that the connection force transmission path between the single connecting member 323 and the cleaning component 20 can be increased, thereby improving the movement consistency and stability of the cleaning component 20 connected to the connecting member 323 driven by the pull wire 322 during the rising process, and avoiding the problem of local collapse and lag of the cleaning component 20 during the rising process (such as unevenness at both ends of the cleaning component 20).

[0089] Specifically, combined Figure 3 , Figure 6-Figure 8 As shown, the body 10 may also be provided with a constraint portion 421. In one embodiment, the constraint portion 421 may be provided on the second base 42. The constraint portion 421 is formed with a cable slot 4211, and the pull wire 322 passes through the cable slot 4211. The constraint portion 421 is formed with a cable slot 4211 that constrains the moving path of the pull wire 322. Part of the pull wire 322 passes through the cable slot 4211 on the path connecting the spool 321 and the cleaning component 20. In this way, the moving path of the pull wire 322 can be limited, and the problem of the pull wire 322 shaking can be avoided, thereby ensuring the movement stability of the cleaning component 20 during the ascending process.

[0090] Furthermore, combined with Figure 5-Figure 8 As shown, the cleaning device 100 further includes an elastic return member 50 , which is disposed between the cleaning assembly 20 and the second base 42 to provide an elastic force for the cleaning assembly 20 to descend.

[0091] Among them, the elastic reset member 50 undergoes elastic deformation to generate an elastic force, and the elastic reset member 50 abuts between the cleaning component 20 and the second base 42. When the cleaning component 20 needs to descend from the raised position, the lifting mechanism 30 stops working or reverses. In this way, under the combined action of the elastic reset force and the cleaning component 20's own gravity, the descending effect can be quickly completed until it contacts the cleaning surface. The cleaning component 20 continues to perform cleaning work (such as mopping, sweeping, etc.), thereby achieving the effect of the cleaning component 20 selectively performing an ascending or descending action.

[0092] Specifically, the lifting mechanism 30 and the translation mechanism 40 are arranged in the machine body 10 , the machine body 10 is provided with a slide groove 11 , and the cleaning component 20 is provided with a connecting portion 23 , and the connecting portion 23 is connected to the lifting mechanism 30 after passing through the slide groove 11 .

[0093] Among them, since the lifting mechanism 30 and the cleaning component 20 are respectively located on the upper and lower sides of the body 10, after the body 10 is provided with the slide groove 11, it is convenient for the connecting part 23 on the cleaning component 20 to directly pass through the slide groove 11 and connect with the lifting mechanism 30 above, which can simplify and shorten the transmission connection path between the lifting mechanism 30 and the cleaning component 20; and the slide groove 11 extends in the horizontal direction, which also makes the connecting part 23 have a certain horizontal sliding range, thereby improving the working efficiency of the translation mechanism 40 to drive the cleaning component 20 (because the cleaning component 20 is connected to the second base 42) to translate as a whole in the horizontal direction.

[0094] Specifically, combined Figure 2 , Figure 6-Figure 8 As shown, the machine body 10 includes a bottom shell 12, a cleaning assembly 20 is arranged below the bottom shell 12, a translation mechanism 40 and a lifting mechanism 30 are arranged above the bottom shell 12, and the bottom shell 12 is provided with a slide groove 11. In this way, the translation mechanism 40 and the lifting mechanism 30 can be further protected and installed and fixed, and the translation mechanism 40 and the lifting mechanism 30 can also be easily disassembled and installed.

[0095] The cleaning component 20 below the bottom shell 12 is connected to the second base 42 through its own connecting portion 23 after passing through the slide groove 11, and the other end of the translation transmission component 43 is connected to the second base 42, so that the cleaning component 20 can smoothly form an indirect connection relationship with the second base 42 and the translation mechanism 40, thereby facilitating the translation mechanism 40 to drive the cleaning component 20 to perform a translation movement along the lateral direction.

[0096] Furthermore, combined with Figure 7-Figure 9As shown, the bottom shell 12 is provided with a first guide portion 121, and the second base 42 is provided with a second guide portion 422, and the second guide portion 422 is guided and matched with the first guide portion 121 in the length direction of the slide slot 11. The first guide portion 121 on the bottom shell 12 is guided and matched with the second guide portion 422 on the second base 42 in the length direction (that is, the transverse direction) of the slide slot 11, so that the second base 42 can be translated according to the specified sliding cooperation path, thereby avoiding the problem of the second base 42 shaking during the translation process, and then ensuring the movement stability of the cleaning component 20 in the translation action along the transverse direction.

[0097] Specifically, one of the first guide portion 121 and the second guide portion 422 is configured as a guide rod and the other is configured as a guide head, the guide head is provided with a guide hole, and the guide rod is provided with the guide hole. For example, the first guide portion 121 is configured as a guide rod (the guide rod extends in the transverse direction), the second guide portion 422 is configured as a guide head, the guide rod is provided with a guide hole in the guide head, and the guide rod guides the movement path of the guide head, so that the guide head can slide along the specified extension direction of the guide rod, thereby improving the movement stability and smoothness of the cleaning assembly 20 in the transverse direction.

[0098] Furthermore, the maximum extension of the cleaning assembly 20 relative to the body 10 in the lateral direction does not exceed the length of the slide slot 11. In this way, the extension size of the cleaning assembly 20 can be limited, avoiding the risk of the cleaning assembly 20 being too large and causing the related electronic components to be easily damaged, thereby ensuring the working stability of the cleaning assembly 20 during the cleaning process.

[0099] The cleaning device 100 according to the second aspect of the present invention includes a cleaning component 20 and a driving mechanism, which is transmission-connected to the cleaning component 20, and drives the cleaning component 20 to move in a first direction and a second direction; wherein, in the first direction, the cleaning component 20 has a first state of contacting the ground and a second state of being away from the ground, and in the second direction, the cleaning component 20 has a third state of being retracted into the cleaning device 100 and a fourth state of being extended out of the cleaning device 100.

[0100] Specifically, the cleaning device 100 switches the working state of the cleaning component 20 in the first direction and the second direction according to different working environments. In this way, the comprehensive cleaning ability of the cleaning device 100 can be improved through the flexible combination of the cleaning component 20 in various states.

[0101] For example, when the cleaning component 20 encounters a conventional working environment such as a floor, the cleaning component 20 is in a first state of contacting the ground in the first direction, and is in a third state of being retracted into the cleaning device 100 in the second direction. For another example, when the cleaning component 20 encounters a special working environment such as a carpet or an obstacle, the cleaning component 20 is in a second state of being away from contacting the ground in the first direction, and is in a third state of being retracted into the cleaning device 100 in the second direction.

[0102] For another example, when the cleaning component 20 is working along the edge of a wall, the cleaning component 20 is in a first state of contacting the ground in the first direction, and is in a fourth state of extending out of the cleaning device 100 in the second direction. For another example, when the cleaning component 20 is working along the edge of a wall and there is an obstacle on the cleaning path, the cleaning component 20 switches from the first state of contacting the ground in the first direction to the second state away from the contacting ground, and is in a fourth state of extending out of the cleaning device 100 in the second direction.

[0103] According to some optional embodiments of the present invention, the first direction and the second direction are perpendicular to each other, so as to avoid the problem of interference and collision between the cleaning assembly 20 when the cleaning assembly 20 moves along the first direction and the second direction at the same time.

[0104] Specifically, the first direction is the vertical direction of the cleaning device 100, and the second direction is the lateral direction of the cleaning device 100. The first direction is the vertical direction of the cleaning device 100 (that is, the up and down direction), and the second direction is the lateral direction of the cleaning device 100 (that is, the left and right direction), so that the cleaning component 20 can be displaced in three directions in space (the first direction and the second direction and the front and back direction of the cleaning component 20 originally on the cleaning path), thereby improving the cleaning ability of the cleaning component 20 in different working environments.

[0105] According to some optional embodiments of the utility model, the cleaning assembly 20 includes a first base 21 and a track brush 22 . The first base 21 is disposed below the machine body 10 . The lifting mechanism 30 is transmission-connected to the first base 21 . The track brush 22 is disposed on the first base 21 .

[0106] Specifically, the track brush 22 is arranged below the first base 21, so that the track brush 22 can directly contact the surface to be cleaned, and the first base 21 can also form a certain protection and fixing effect on the track brush 22; and the lifting mechanism 30 is transmission-connected with the first base 21 below the body 10, so that the lifting mechanism 30 can indirectly achieve the effect of driving the track brush 22 to rise by driving the first base 21 to rise, thereby improving the design rationality and scientificity of the cleaning component 20.

[0107] According to some optional embodiments of the utility model, the driving mechanism includes a lifting mechanism 30 and a translation mechanism 40. The lifting mechanism 30 is transmission-connected to the cleaning component 20 to selectively drive the cleaning component 20 to move along a first direction. The lifting mechanism 30 is arranged on the translation mechanism 40 to drive the cleaning component 20 to move along a second direction under the drive of the translation mechanism 40.

[0108] In detail, the translation mechanism 40 is arranged on the body 10, and the translation mechanism 40 and the lifting mechanism 30 are both transmission connected to the cleaning component 20, so that the lifting mechanism 30 can selectively drive the cleaning component 20 under the body 10 to rise, and can also facilitate the translation mechanism 40 to drive the cleaning component 20 to extend along the lateral direction of the cleaning equipment 100.

[0109] Specifically, the translation mechanism 40 includes a translation drive 41, a second base 42 and a translation transmission assembly 43. The lifting mechanism 30 is arranged on the second base 42. One end of the translation transmission assembly 43 is connected to the translation drive 41, and the other end of the translation transmission assembly 43 is connected to the second base 42. The translation drive 41 selectively drives the second base 42 to move along the second direction through the translation transmission assembly 43.

[0110] The two ends of the translation transmission assembly 43 are respectively connected to the translation driving member 41 and the second base 42, and the driving member can indirectly transmit the driving force to the second base 42 through the translation transmission assembly 43, so as to achieve the effect of driving the second base 42, the lifting mechanism 30 and the cleaning assembly 20 to translate as a whole along the second direction, thereby improving the scientificity and design rationality of the translation mechanism 40. For example, the translation driving member 41 can be a motor, but is not limited thereto, so that the second base 42, the lifting mechanism 30 and the cleaning assembly 20 can be respectively achieved by the forward and reverse rotation of the motor to achieve the overall reciprocating translation effect along the second direction.

[0111] Furthermore, the lifting mechanism 30 includes a lifting drive member 31 and a lifting transmission assembly 32. The lifting drive member 31 is arranged on the second base 42. One end of the lifting transmission assembly 32 is connected to the lifting drive member 31, and the other end of the lifting transmission assembly 32 is connected to the cleaning assembly 20. The lifting drive member 31 selectively drives the cleaning assembly 20 to move along the first direction through the lifting transmission assembly 32.

[0112] The two ends of the lifting transmission assembly 32 are respectively connected to the lifting drive member 31 and the cleaning assembly 20, and the lifting drive member 31 can transmit the driving force to the cleaning assembly 20 through the lifting transmission assembly 32, so as to achieve the effect of driving the cleaning assembly 20 to translate as a whole along the first direction, thereby improving the scientificity and design rationality of the lifting mechanism 30. For example, the lifting drive member 31 can be a motor, but is not limited thereto, so that the overall reciprocating translation effect of the cleaning assembly 20 along the first direction can be achieved by the forward and reverse rotation of the motor.
