TECHNICAL FIELD

[0001] The present application relates to the technical field of sweeping robots, and in particular to a sweeping robot and a mop mechanism thereof. BACKGROUND

[0002] With the development of technology, the functions of sweeping robots are becoming more and more comprehensive. The rear half of the sweeping robot is configured with a mop mechanism, which can extend out of the body to clean, reducing the blind area of the machine. When the ground does not need to be cleaned, the mop mechanism can be lifted in the body to leave the ground. After the mop mechanism is lifted, a shielding member can also be used to shield the mop to avoid the mop from polluting the area that cannot be cleaned such as the carpet.

[0003] Because the sweeping robot has multiple actions such as extension, lifting and shielding, multiple motors need to be configured in the prior art to drive the mop mechanism and the shielding member respectively to realize the extension-retraction-lifting function of the mop mechanism and the shielding function of the shielding member. This results in high product cost, large installation space, and is not conducive to reducing the structure size. The control of multiple motors requires specific logical relationship, and the motor control program is complex and prone to failure. SUMMARY

[0026] The swing driving member 8 is capable of converting the cleaning assembly 3 between the accommodation lifting state and the accommodation landing state with the movement of the connecting member 4.

[0027] In the process of converting the cleaning assembly 3 between the accommodation lifting state and the accommodation landing state, the linkage transmission member 7 is capable of automatically driving the shielding cover 6 to slide to the upper part of the mop cover 31 to expose the roller mop 32, and to slide to the lower part of the mop cover 31 to shield the roller mop 32.

[0028] The mop mechanism for a sweeping robot is a component of a sweeping robot, and is generally installed at the rear half of the body of the sweeping robot according to the direction of the sweeping robot.

[0029] The mop mechanism for a sweeping robot comprises a housing 1, a fixed frame 2, a cleaning assembly 3, a connecting member 4, a linear driving member 5, a shielding cover 6, a linkage transmission member 7 and a swing driving member 8.

[0030] In the present application, the cleaning assembly 3 can extend to one side to clean the corners of the floor. The direction in which the cleaning assembly 3 extends is substantially perpendicular to the direction of the robot cleaner. If the direction in which the robot cleaner moves is defined as the front direction, then the direction in which the cleaning assembly 3 extends can be the left side or the right side. For the sake of convenience, the direction in which the cleaning assembly 3 extends or the side is referred to as the distal side in the present application, and the side opposite to the direction in which the cleaning assembly 3 extends is referred to as the proximal side. Accordingly, the end of the mop mechanism of the robot cleaner and each component of the robot cleaner arranged substantially perpendicular to the front-rear direction towards the distal side is referred to as the distal end, and the other end thereof is referred to as the proximal end.

[0031] The housing 1 is the rear half housing of the robot cleaner, and has a proximal end panel 1a and a distal end panel 1b arranged opposite to each other. The proximal end panel 1a and the distal end panel 1b are arranged apart along the width direction or the left-right direction of the robot cleaner.

[0032] The bottom of the housing 1 is provided with a bottom recess 11 extending along the direction from the proximal end panel 1a to the distal end panel 1b. The bottom recess 11 can accommodate the cleaning assembly 3, and the bottom slot of the bottom recess 11 is used for the cleaning assembly 3 to swing down to the ground and swing up to retract.

[0033] In the extending direction of the bottom recess 11, the bottom recess 11 has a proximal end slot 11a and a distal end slot 11b. The proximal end slot 11a is provided on the proximal end panel 1a, and the distal end slot 11b is provided on the distal end panel 1b. The proximal end slot 11a exposes a part of the proximal end 3a of the cleaning assembly 3, and a user can install accessories through the proximal end slot 11a. The size of the distal end slot 11b is greater than the size of the distal end 3b of the cleaning assembly 3, and the distal end 3b of the cleaning assembly 3 can extend out of or retract into the distal end slot 11b.

[0034] The fixing frame 2 is longitudinally long, and is mounted on the bottom of the housing 1 and extends along the left-right direction or transversely. The fixing frame 2 is mounted on the rear side of the bottom recess 11. The proximal end of the fixing frame 2 has a proximal end block 2a, and the distal end thereof has a distal end block 2b.

[0035] Mounting holes 14 are provided on the housing 1 at positions corresponding to the proximal end block 2a and the distal end block 2b, and screws 22 are used to pass downward through the mounting holes 14 to fix the proximal end block 2a and the distal end block 2b on the bottom of the housing 1.

[0036] The cleaning assembly 3 is longitudinally long as a whole, and extends along the right direction or transversely. The cleaning assembly 3 includes a proximal end 3a and a distal end 3b arranged opposite to each other.

[0037] Specifically, the cleaning assembly 3 comprises a mop cover 31 and a mop roller 32. The mop cover 31 is longitudinally shaped and arched in cross section for mounting the mop roller 32. The bottom of the mop cover 31 has a bottom opening 311. The mop roller 32 is mounted in the mop cover 31 by a rotating shaft, or the mop roller 32 is mounted on a driving shaft in the mop cover 31 so as to be driven to rotate. The radius of the mop roller 32 is greater than that of the mop cover 31, and the bottom part of the mop roller 32 is exposed from the bottom opening 311 of the mop cover 31.

[0038] The proximal end of the mop cover 31 is provided with a proximal end cover 31a, and the distal end of the mop cover 31 is provided with a distal end cover 31b. The proximal end 32a of the mop roller 32 is pivotally connected to the proximal end cover 31a, and the distal end 32b of the mop roller 32 is pivotally connected to the distal end cover 31b. The proximal end cover 31a and the proximal end 32a of the mop roller 32 belong to the proximal end 3a of the cleaning assembly 3. The distal end cover 31b and the distal end 32b of the mop roller 32 belong to the distal end 3b of the cleaning assembly 3.

[0039] The proximal end cover 31a is provided with a proximal end shield 31c for shielding a part of the linkage transmission member 7, such as a transmission gear 72. The distal end cover 31b is provided with a detachable baffle 31d for blocking the distal end 32b of the assembled mop roller 32. When the mop roller 32 needs to be removed, the detachable baffle 31d is removed, and the mop roller 32 is taken out of the distal end slot 11b for replacement.

[0040] The rear part of the mop cover 31 is provided with a swing arm 31e hinged to the connecting member 4, so that the mop cover 31 can swing up and down relative to the connecting member 4. The cleaning assembly 3 can be lifted or swung up to lift the mop roller 32 off the ground, and the cleaning assembly 3 can be lowered or swung down to lower the mop roller 32 to the ground.

[0041] The connecting member 4 is composed of one or more components. The connecting member 4 is in sliding connection with the fixed frame 2, so it can slide linearly relative to the fixed frame 2 to drive the cleaning assembly 3 to slide linearly. For example, the connecting member 4 is driven to slide from the proximal side to the distal side to drive the distal end 3b of the cleaning assembly 3 to extend out of the distal end slot 11b; for another example, the connecting member 4 is driven to slide from the distal side to the proximal side to drive the distal end 3b of the cleaning assembly 3 to retract into the distal end slot 11b.

[0042] An opening 12 is provided on the top surface of the housing 1 to avoid the components of the sliding connecting member 4, such as the later-mentioned translation frame 42 and sliding seat 43.

[0043] A motor mounting groove 13 is provided on the top surface of the housing 1 for mounting the later-mentioned motor 511.

[0044] The linear driving member 5 is connected with the housing 1 and the connecting member 4. The linear driving member 5 can be a combination of a motor linear driving member and an elastic member. The linear driving member 5 is used to drive the connecting member 4 to reciprocate linearly on the fixed frame 2. For example, the linear driving member 5 drives the connecting member 4 to slide from the proximal side to the distal side to drive the distal end 3b of the cleaning assembly 3 to extend out of the distal end slot 11b; for another example, the linear driving member 5 drives the connecting member 4 to slide from the distal side to the proximal side to drive the distal end 3b of the cleaning assembly 3 to retract into the distal end slot 11b.

[0045] The shielding cover 6 is arranged on the outer circumferential surface or the upper surface of the mop cover 31. The shielding cover 6 is arc-shaped and is adapted to the surface of the mop cover 31. The distal end 6b of the shielding cover 6 is slidingly connected with the distal end of the mop cover 31, and the proximal end 6a of the shielding cover 6 is slidingly arranged on the proximal end of the mop cover 31. The shielding cover 6 is slidingly connected with the mop cover 31 and can be driven to reciprocate along the circumference of the mop cover 31, so as to switch positions between the upper portion and the lower portion of the mop cover 31.

[0046] When the cleaning assembly 3 is lowered and the roller mop 32 falls to the ground, the shielding cover 6 is located at the upper portion of the mop cover 31, exposing the bottom portion of the lower roller mop 32, and does not affect the normal use of the roller mop 32.

[0047] When the cleaning assembly 3 is lifted and the roller mop 32 is away from the ground, the shielding cover 6 is located at the lower portion of the mop cover 31 to shield or cover the roller mop 32, exposing the bottom portion of the mop cover 31, so as to avoid the pollution of the roller mop 32 and the sweeping of particulate garbage into the mop cover 31.

[0048] The linkage transmission member 7 is arranged between the mop cover 31 and the shielding cover 6 and is used to drive the shielding cover 6 to slide to expose or shield the roller mop 32 according to the up-down swinging of the mop cover 31. The linkage transmission member 7 can be a gear, a rack, a rocker, or the like.

[0049] When the cleaning assembly 3 is lifted, the mop cover 31 swings upward, and the shielding cover 6 slides to the lower portion of the mop cover 31 under the action of the linkage transmission member 7, thereby shielding the bottom of the roller mop 32 and playing a protection role.

[0050] When the cleaning assembly 3 is lowered to fall to the ground, the mop cover 31 swings downward, and the shielding cover 6 slides to the upper portion of the mop cover 31 under the action of the linkage transmission member 7, thereby exposing the bottom of the roller mop 32 and not affecting the cleaning function of the roller mop 32.

[0051] The swing driving member 8 is arranged between the mop cover 31 and the connecting member 4, and is used to drive the mop cover 31 retracted into the bottom groove 11 to swing upward to lift the mop cover 31 to drive the roller mop 32 off the ground. The swing driving member 8 can adopt a guide mode of wedge-shaped guide structure and guide hook, or a guide mode of inclined surface and boss, or a mode of magnet adsorption.

[0052] When the roller mop 32 of the cleaning assembly 3 retracted into the bottom groove 11 falls to the ground, the distal end 3b of the cleaning assembly 3 is inside the distal end slot 11b of the bottom groove 11.

[0053] For the convenience of description, the state that the distal end 3b of the cleaning assembly 3 is extended out of the distal end slot 11b and the roller mop 32 is grounded is referred to as an extended ground state of the cleaning assembly 3; the state that the distal end 3b of the cleaning assembly 3 is retracted into the distal end slot 11b and the roller mop 32 is grounded is referred to as a retracted ground state of the cleaning assembly 3. When the cleaning assembly 3 in the retracted ground state is driven by the connecting member 4 to move toward the proximal side, the swing driving member 8 drives the mop cover 31 to swing upward to lift the mop cover 31 to drive the roller mop 32 off the ground. For the convenience of description, the state that the cleaning assembly 3 retracted into the bottom groove 11 is driven to lift to drive the roller mop 32 off the ground is referred to as a retracted lifting state.

[0054] When the cleaning assembly 3 in the retracted lifting state is driven by the connecting member 4 to move toward the distal side by a first distance, the cleaning assembly 3 is lowered to the ground by gravity or the force of the torsional spring, and the cleaning assembly 3 is converted to the retracted ground state. When the cleaning assembly 3 in the retracted ground state is driven by the connecting member 4 to move toward the distal side by a second distance, the cleaning assembly 3 is converted to the extended ground state.

[0055] When the swing driving member 8 drives the mop cover 31 to swing upward to lift the mop cover 31 to drive the roller mop 32 off the ground, the shielding cover 6 is driven by the linkage transmission member 7 to slide to the lower part of the mop cover 31, thereby shielding the bottom of the roller mop 32, and playing a protection role.

[0056] When the cleaning assembly 3 is converted from the retracted lifting state to the retracted ground state, the mop cover 31 and the roller mop 32 swing downward until the roller mop 32 falls to the ground, and the shielding cover 6 is driven by the linkage transmission member 7 to slide to the upper part of the mop cover 31, thereby exposing the bottom of the roller mop 32, and not affecting the cleaning function of the roller mop 32.

[0057] In conclusion, the mop cloth mechanism of the present application is provided with a set of linear driving members 5 to drive the connecting member 4 to move linearly, thereby driving the cleaning assembly 3 to move linearly, a set of pure mechanical swing driving members 8 to switch the cleaning assembly 3 between the storage lifting state and the storage landing state along with the movement of the cleaning assembly 3, and a set of pure mechanical linkage transmission members 7 to adaptively drive the shielding cover 6 to slide to expose or shield the roller mop 32 according to the up-down swing of the mop cover 31, thereby saving the number of motors, reducing the product cost, facilitating the reduction of the structure size, simplifying the control program, and prolonging the service life of the product.

[0058] In one embodiment, as shown in Figures 3-4 、 Figure 8 and Figures 16-21 , the connecting member 4 comprises a sliding frame 41, a translation frame 42 and a sliding seat 43.

[0059] The sliding frame 41 is slidably connected with the fixed frame 2, the translation frame 42 is fixedly connected with the sliding frame 41, and the translation frame 42 is slidably assembled between the proximal end and the distal end of the fixed frame 2.

[0060] The mop cover 31 is located on one side of the sliding frame 41 and is hingedly connected with the sliding frame 41.

[0061] The sliding seat 43 is slidably connected with the translation frame 42 and can slide between the proximal end and the distal end of the translation frame 42.

[0062] The swing driving member 8 is assembled between the sliding seat 43 and the mop cover 31.

[0063] The linear driving member 5 can drive the sliding frame 41 and the sliding seat 43 to reciprocatingly move linearly.

[0064] When the cleaning assembly 3 is in the storage landing state and the extended landing state, the swing driving member 8 is in the separated state.

[0065] When the cleaning assembly 3 is in the storage lifting state, the swing driving member 8 is in the combined state.

[0066] In this embodiment, the connecting member 4 comprises the sliding frame 41, the translation frame 42 and the sliding seat 43.

[0067] The slide frame 41 is longitudinally long, and is used to assemble the cleaning assembly 3 and to drive the cleaning assembly 3 to slide along the left-right direction. The slide frame 41 is assembled on one side of the fixed frame 2, for example, the lower side or the rear side, and the slide frame 41 can slide relative to the fixed frame 2 along the left-right direction. The slide frame 41 and the fixed frame 2 can be connected through a linear guide structure to guide the sliding of the slide frame 41. In the left-right direction, the slide frame 41 has a proximal end 41a and a distal end 41b. The length of the slide frame 41 is longer than that of the fixed frame 2 so as to be assembled with the longer cleaning assembly 3.

[0068] A translation frame 42 is fixedly arranged at the substantially central position of one side of the slide frame 41, and the translation frame 42 is slidingly connected with the fixed frame 2 and can slide back and forth between the proximal end block 2a and the distal end block 2b.

[0069] The cleaning assembly 3 is arranged on one side of the slide frame 41, specifically, the front side. The two ends of the side of the slide frame 41 facing the cleaning assembly 3 are respectively provided with mounting ports 411, which have mounting shafts inside and are used to mount the swing arms 31e on the rear side of the mop cover 31. The swing arms 31e can swing up and down in the mounting ports 411 to drive the cleaning assembly 3 to swing up and down. According to needs, torsional springs can be assembled between the mounting shafts and the swing arms 31e to press the swing arms 31e downward so that the mop roller 32 of the cleaning assembly 3 can be pressed against the ground.

[0070] The slide seat 43 is slidingly connected with the translation frame 42 and can slide between the proximal end and the distal end of the translation frame 42.

[0071] The slide seat 43 is assembled on the translation frame 42 and can slide between the proximal end block 42a and the distal end block 42b of the translation frame 42. The swing driving member 8 is assembled between the slide seat 43 and the mop cover 31.

[0072] The linear driving member 5 is drivingly connected with the slide frame 41 and the slide seat 43 to drive the slide frame 41 and the slide seat 43 to reciprocatingly move linearly.

[0073] The swing driving member 8 can be similar to a clutch and has a disengaged state and an engaged state.

[0074] When the cleaning assembly 3 is in the stowed state and the extended state, the swing driving member 8 is in the disengaged state, that is, the swing driving member 8 does not act on the mop cover 31 and does not lift the mop cover 31.

[0075] When the cleaning assembly 3 is in the stowed and lifted state, the swing driving member 8 is in the engaged state, that is, the swing driving member 8 acts on the mop cover 31 and lifts the mop cover 31.

[0076] In one of the embodiments, as shown in Figure 4 , Figures 8-13 ,Figure 16 、 Figures 18-20 and Figure 28 As shown in FIGS. 8, 9 and 10, the swing driving member 8 comprises a wedge-shaped guide block 81 arranged on the slide 43 near the mop cover 31 and a hook 82 arranged on the mop cover 31 near the slide 43.

[0077] When the cleaning assembly 3 is in the stowed floor state and the extended floor state, the wedge-shaped guide block 81 is distal to the hook 82.

[0078] When the cleaning assembly 3 is in the stowed raised state, the wedge-shaped guide block 81 is fitted in the hook 82, so that the cleaning assembly 3 swings upwardly.

[0079] In the embodiment, the swing driving member 8 adopts the combined structure of the wedge-shaped guide block 81 and the hook 82. The wedge-shaped guide block 81 is fixedly arranged on one side of the slide 43 near the mop cover 31, and the hook 82 is fixedly arranged on the rear side of the mop cover 31.

[0080] The hook 82 is located obliquely above the mop cover 31 to match the height of the wedge-shaped guide block 81.

[0081] In the direction from the proximal side to the distal side, the thickness of the wedge-shaped guide block 81 gradually increases. In the direction from the proximal side to the distal side, the guide slope 811 at the top of the wedge-shaped guide block 81 gradually extends upwardly. When the wedge-shaped guide block 81 is inserted into the hook 82 from the distal side to the proximal side, the guide slope 811 drives the hook 82 to swing upwardly, thereby driving the cleaning assembly 3 to swing upwardly.

[0082] When the cleaning assembly 3 is in the stowed floor state and the extended floor state, the slide 43 remains in the initial position, which is abutted against the inner side of the distal end baffle 42b of the translation frame 42, so that the wedge-shaped guide block 81 remains distal to the hook 82. At this time, the wedge-shaped guide block 81 is separated from the hook 82, the swing driving member 8 is in the separated state, the swing driving member 8 does not act on the mop cover 31, and the mop cover 31 is not lifted.

[0083] When the cleaning assembly 3 is in the stowed floor state, the proximal end of the wedge-shaped guide block 81 is substantially located at the distal side opening of the hook 82. At this time, if the linear driving member 5 drives the slide 43 to move on the translation frame 42 toward the proximal side, the slide 43 will drive the wedge-shaped guide block 81 to cooperate with the hook 82, so that the cleaning assembly 3 is lifted. When the slide 43 stops moving at the proximal end baffle 42a of the translation frame 42, it indicates that the cleaning assembly 3 is completed to be lifted.

[0084] In one of the embodiments, as shown in FIG. 11, the swing driving member 8 comprises a wedge-shaped guide block 81 arranged on the slide 43 near the mop cover 31 and a hook 82 arranged on the mop cover 31 near the slide 43. Figures 16-19As shown in the drawings, the mounting base 9 is arranged at the bottom of the sliding frame 41 and is fixedly connected with the shell 1. The sliding frame 41 is above the mounting base 9 and can slide. The mounting base 9 is at the rear side of the mop cover 31. The rear side of the mop cover 31 is provided with a long strip-shaped boss 312. The hook 82 can be arranged on the boss 312. When the cleaning assembly 3 is lowered to the limit position, the boss 312 falls on the mounting base 9, thereby playing a limiting role.

[0085] In one embodiment, as shown in Figure 21 and Figure 28 The fixed frame 2 includes a first guide rod 21 connected between the proximal block 2a and the distal block 2b.

[0086] The translation frame 42 is slidably connected with the first guide rod 21, and / or the sliding seat 43 is slidably connected with the first guide rod 21.

[0087] In this embodiment, the fixed frame 2 mainly includes the proximal block 2a, a plurality of first guide rods 21, and the distal block 2b. The first guide rods 21 are connected between the proximal block 2a and the distal block 2b.

[0088] The translation frame 42 is provided with a first through hole corresponding to the position of the first guide rod 21. The first guide rod 21 passes through the first through hole, and the translation frame 42 can slide along the first guide rod 21.

[0089] Preferably, the fixed frame 2 includes two horizontally and spacedly arranged first guide rods 21. The translation frame 42 is provided with two horizontally and spacedly arranged first through holes. The two first guide rods 21 pass through the two first through holes, respectively, to stably support the translation frame 42.

[0090] In this embodiment, the sliding seat 43 can also be slidably connected with the first guide rod 21 to improve the sliding stability of the sliding seat 43. The sliding seat 43 is provided with a second through hole 434 corresponding to the position of the first guide rod 21. The first guide rod 21 passes through the second through hole 434, and the sliding seat 43 can slide along the first guide rod 21.

[0091] Preferably, the sliding seat 43 is provided with two horizontally and spacedly arranged second through holes 434. The two first guide rods 21 pass through the two second through holes 434, respectively, to stably support the sliding seat 43.

[0092] In one embodiment, as shown in Figure 21 and Figure 28 The translation frame 42 includes a proximal baffle 42a, a distal baffle 42b, and a second guide rod 421 connected between the proximal baffle 42a and the distal baffle 42b.

[0093] The proximal baffle 42a and the distal baffle 42b are respectively connected with the sliding frame 41. The sliding seat 43 is slidably connected with the second guide rod 421.

[0094] In the embodiment, the translation frame 42 mainly consists of a proximal baffle 42a, a second guide rod 421 and a distal baffle 42b. The second guide rod 421 is connected between the proximal baffle 42a and the distal baffle 42b.

[0095] The proximal baffle 42a and the distal baffle 42b are connected with the sliding frame 41 respectively to realize integral sliding of the two. The sliding seat 43 is provided with a third through hole 435, and the second guide rod 421 passes through the third through hole 435. The sliding seat 43 can slide along the second guide rod 421 to improve the sliding stability of the sliding seat 43.

[0096] In one of the embodiments, as shown in Figures 3-4 Figure 8 Figures 16-27 The linear driving member 5 mainly consists of a motor driving assembly 51, a first elastic member 52 and a second elastic member 53.

[0097] The motor driving assembly 51 is connected with the sliding seat 43 and is used to drive the sliding seat 43 and / or the sliding frame 41 to move towards the proximal side.

[0098] The first elastic member 52 is connected with the sliding frame 41 and is used to drive the sliding frame 41 to move towards the distal side on the fixed frame 2.

[0099] The second elastic member 53 is connected with the sliding seat 43 and is used to drive the sliding seat 43 to move towards the distal side on the translation frame 42.

[0100] In the embodiment, the linear driving member 5 mainly consists of the motor driving assembly 51, the first elastic member 52 and the second elastic member 53.

[0101] The first elastic member 52 can be an elastic member or a spring. The proximal end 52a of the first elastic member 52 is connected with the sliding frame 41, and the distal end 52b is connected with the fixed frame 2 or the shell 1. The first elastic member 52 provides a pulling force for the sliding frame 41 to move towards the distal side, so as to drive the sliding frame 41 to move towards the distal side relative to the fixed frame 2, thereby driving the distal end 3b of the cleaning assembly 3 to extend out of the distal slot 11b to reach the purpose of being able to clean the corner of the floor.

[0102] The motor driving assembly 51 is in transmission connection with the sliding frame 41, and the transmission connection includes direct connection or indirect connection, as long as the motor driving assembly 51 can drive the sliding frame 41 to move towards the proximal side. When the motor driving assembly 51 is in the first working state, it provides a pulling force for the sliding frame 41 to move towards the proximal side, which overcomes the force of the first elastic member 52, so as to drive the cleaning assembly 3 to move towards the proximal side and retract into the bottom groove 11.

[0103] ​​The second elastic member 53 can be a selected elastic member or spring, the proximal end 53a of which is connected with the sliding seat 43, and the distal end 53b of which is connected with the distal end 41b of the sliding frame 41. The second elastic member 53 provides a pulling force for the sliding seat 43 to move towards the distal end, so that the sliding seat 43 leans against the inner side of the distal end baffle 42b of the translation frame 42. The second elastic member 53 is used to drive the sliding seat 43 to move towards the distal end so that the wedge-shaped guide block 81 is separated from the hook 82.

[0104] The motor driving assembly 51 is in transmission connection with the sliding seat 43. The motor driving assembly 51 directly acts on the sliding seat 43 through a transmission mechanism, which can drive the sliding seat 43 to move towards the proximal end on the translation frame 42, so as to drive the wedge-shaped guide block 81 to cooperate with the hook 82, thereby lifting the cleaning assembly 3. When the motor driving assembly 51 is in the second working state, it provides a pulling force for the sliding seat 43 to move towards the proximal end, which overcomes the force of the second elastic member 53, so as to drive the sliding seat 43 to move towards the proximal end until it moves to the proximal end baffle 42a of the translation frame 42.

[0105] According to needs, the cleaning assembly 3 in the storage lifting state, the storage landing state and the extension landing state can be defined as initial states respectively. For the convenience of description, the cleaning assembly 3 in the storage lifting state is defined as the initial state in the present application.

[0106] In the present application, the first working state and the second working state of the motor driving assembly 51 are respectively used to overcome the forces of the first elastic member 52 and the second elastic member 53, and to pull the corresponding components to move towards the proximal end. After moving to the position, the motor driving assembly 51 stops running and can keep the corresponding components at the corresponding positions.

[0107] The motor driving assembly 51 can be connected with the sliding frame 41 and the sliding seat 43 through two sets of transmission mechanisms respectively, or can be connected with the sliding seat 43 through one set of transmission mechanism, and then drives the sliding frame 41 to move towards the proximal end through the sliding seat 43 and the translation frame 42.

[0108] The working mode of the cleaning device provided by the present application is as follows: When in the initial state, the motor driving assembly 51 is in the initial state, the first elastic member 52 and the second elastic member 53 are in the elongated state, and the cleaning assembly 3 is in the storage lifting state.

[0109] When the ground needs to be cleaned, the motor driving assembly 51 releases the pulling force on the sliding seat 43. Under the action of the second elastic member 53, the sliding seat 43 moves on the translation frame 42 from the proximal end to the distal end until it slides to the distal end of the translation frame 42 and is blocked by the distal end baffle 42b. The wedge-shaped guide block 81 is separated from the hook 82, and the cleaning assembly 3 swings downward under the action of gravity and / or the torsional spring and presses on the ground.

[0110] When it is needed to clean the corner of the floor, the motor driving assembly 51 releases the pulling force on the sliding frame 41, under the action of the first elastic member 52, the sliding frame 41 moves towards the far side until the sliding frame 42 slides to the far end of the fixed frame 2 and is blocked by the far end block 2b. In this process, the sliding frame 41 drives the cleaning assembly 3 to move towards the far side, so that the far end 3b of the cleaning assembly 3 extends out of the far end slot 11b of the bottom groove 11, realizing the function of cleaning the corner of the floor.

[0111] When it is needed to retract the cleaning assembly 3, the motor driving assembly 51 pulls the sliding frame 41 to move towards the near side against the action of the first elastic member 52, until the sliding frame 42 slides to the near end of the fixed frame 2 and is blocked by the near end block 2a, indicating that the cleaning assembly 3 is retracted in place.

[0112] When it is needed to lift the cleaning assembly 3, the motor driving assembly 51 pulls the sliding seat 43 to move towards the near side against the action of the second elastic member 53, until the sliding seat 43 slides to the near end of the sliding frame 42 and is blocked by the near end block 42a, indicating that the wedge-shaped guide block 81 is completely inserted into the hook 82, and the cleaning assembly 3 is lifted to the maximum angle.

[0113] In the present application, the extension and retraction of the cleaning assembly 3 and the lifting action share a set of motor driving assembly 51, which saves cost, is convenient to install, and is conducive to reducing the size of the product.

[0114] In one embodiment, as shown in Figure 21 、 Figure 23 、 Figure 25 and Figures 27-28 , the sliding frame 41 is arranged at the bottom of the fixed frame 2, and the sliding frame 42 is arranged at the top of the sliding frame 41.

[0115] The bottom plate of the sliding frame 41 is provided with an opening portion 412 for avoiding the sliding seat 43, and the lower end portion 433 of the sliding seat 43 passes through the opening portion 412 downward.

[0116] The second elastic member 53 is connected at the bottom of the sliding frame 41, the far end 53b of the second elastic member 53 is connected with the far end 41b of the sliding frame 41, and the near end 53a of the second elastic member 53 is connected to the lower end portion 433 of the sliding seat 43.

[0117] In this embodiment, in order to save installation space, the sliding frame 41 is arranged at the bottom of the fixed frame 2, and the sliding frame 42 is fixedly arranged at the top of the sliding frame 41 to be slidingly connected with the fixed frame 2.

[0118] The second elastic member 53 is arranged at the bottom of the sliding frame 41. In order to connect the sliding seat 43 and the second elastic member 53, an opening 412 is arranged at the bottom of the sliding frame 41, which is used to avoid the lower end 433 of the sliding seat 43. The lower end 433 of the sliding seat 43 passes through the opening 412 downwards to connect with the proximal end 53a of the second elastic member 53, and the distal end 53b of the second elastic member 53 is connected with the distal end 41b of the sliding frame 41.

[0119] In one of the embodiments, as shown in Figures 21-27 the preset elastic force of the second elastic member 53 is greater than the preset elastic force of the first elastic member 52.

[0120] When the cleaning assembly 3 is in the extended floor state, the sliding seat 43 is at the distal end of the translation frame 42, and the translation frame 42 is at the distal end of the fixed frame 2.

[0121] When the cleaning assembly 3 is in the storage floor state, the sliding seat 43 is at the distal end of the translation frame 42, and the translation frame 42 is at the proximal end of the fixed frame 2.

[0122] When the cleaning assembly 3 is in the storage lifting state, the sliding seat 43 is at the proximal end of the translation frame 42, and the translation frame 42 is at the proximal end of the fixed frame 2.

[0123] In this embodiment, by setting the preset elastic force of the second elastic member 53 to be greater than the preset elastic force of the first elastic member 52, the motor driving assembly 51 can be directly connected with the sliding seat 43 without being connected with the sliding frame 41, so that the transmission mechanism can be saved and the arrangement is facilitated.

[0124] The preset elastic force of the elastic member includes the pre-tightening force of the elastic member in the initial state and the tensioning force of the elastic member when being stretched to the limit position.

[0125] When the translation frame 42 is at the distal end of the fixed frame 2 and is blocked by the distal end block 2b, the first elastic member 52 is in the initial state, and the pre-tightening force of the first elastic member 52 is F1. When the translation frame 42 is at the proximal end of the fixed frame 2 and is blocked by the proximal end block 2a, the first elastic member 52 is in the stretched state, and the tensioning force of the first elastic member 52 is F2.

[0126] When the sliding seat 43 is at the distal end of the translation frame 42 and is blocked by the distal end block 42b, the second elastic member 53 is in the initial state, and the pre-tightening force of the second elastic member 53 is F3. When the sliding seat 43 is at the proximal end of the translation frame 42 and is blocked by the proximal end block 42a, the second elastic member 53 is in the stretched state, and the tensioning force of the second elastic member 53 is F4.

[0127] Since the preset elastic force of the second elastic member 53 is greater than the preset elastic force of the first elastic member 52, F4>F3>F2>F1.

[0128] Therefore, when the motor driving assembly 51 needs to pull the sliding frame 41 to move proximally, a pulling force between F2 and F3 is applied to the sliding seat 43 to overcome the first elastic member 52 without stretching the second elastic member 53. In this process, the force of the motor driving assembly 51 is transmitted to the sliding frame 41 through the sliding seat 43 and the translation frame 42. The sliding frame 41 is pulled to move proximally until the translation frame 42 moves to the proximal end of the fixed frame 2 and is blocked by the proximal end block 2a, and the sliding seat 43 can remain at the distal end of the translation frame 42. At this time, the cleaning assembly 3 is in a stowed state.

[0129] When it is needed to lift the cleaning assembly 3 off the ground, the motor driving assembly 51 applies a pulling force greater than F4 to the sliding seat 43 to overcome the second elastic member 53, so that the sliding seat 43 slides from the distal end to the proximal end of the translation frame 42, thereby driving the wedge-shaped guide block 81 to insert into the hook 82 to drive the cleaning assembly 3 to swing upward and lift up.

[0130] In one embodiment, as shown in Figures 16-20 the motor driving assembly 51 comprises a motor 511, a winch 512 connected to the output shaft of the motor 511, and a pulling rope 513 connected to the winch 512.

[0131] The motor 511 is fixedly installed on the proximal side of the fixed frame 2, and the pulling rope 513 is connected to the sliding seat 43.

[0132] In this embodiment, the motor driving assembly 51 mainly comprises the motor 511, the winch 512, and the pulling rope 513. The motor 511 can be a servo motor or a stepper motor. The motor 511 is fixedly installed on the proximal side of the fixed frame 2, and the motor 511 can be installed on the housing 1. The motor 511 can rotate in both forward and reverse directions. The winch 512 is used to wind the pulling rope 513, and the winch 512 is installed on the output shaft of the motor 511 and can be driven to rotate in both forward and reverse directions, so as to retract and release the pulling rope 513. The pulling rope 513 can be a pulling rope, a steel wire rope, etc., and is connected to the sliding seat 43.

[0133] When the winch 512 is driven to rotate in the forward direction, the winch 512 retracts the pulling rope 513, and at the same time pulls the sliding seat 43 to overcome the force of the second elastic member 53, so that the sliding seat 43 moves proximally to make the wedge-shaped guide block 81 insert into the hook 82 to drive the cleaning assembly 3 to lift up. When the winch 512 is driven to rotate in the reverse direction, the winch 512 releases the pulling rope 513, and under the action of the second elastic member 53, the sliding seat 43 moves distally to make the wedge-shaped guide block 81 move away from the hook 82, and the cleaning assembly 3 naturally swings down to the ground.

[0134] In one embodiment, as shown in Figures 16-20As shown, the slide 43 is provided with a guide wheel 432, and the pull cable 513 is guided by the guide wheel 432, and the end 5131 of the pull cable 513 is fixed to one side of the proximal end block 2a.

[0135] In this embodiment, the slide 43 is provided with a guide wheel 432 for guiding the pull cable 513, and the end 5131 of the pull cable 513 is fixed to one side of the proximal end block 2a. In this way, the guide wheel 432 not only plays a guiding role, but also plays the role of a fixed pulley, which can speed up the movement of the slide 43.

[0136] In one embodiment, as shown in Figures 3-4 , Figure 8 and Figures 10-11 , the linkage transmission member 7 is arranged between the proximal side of the mop cover 31 and the proximal panel 1a of the housing 1.

[0137] When the cleaning assembly 3 is in the stowed floor state and the extended floor state, the linkage transmission member 7 is in the disengaged state.

[0138] When the cleaning assembly 3 is in the stowed raised state, the linkage transmission member 7 is in the engaged state.

[0139] In this embodiment, the linkage transmission member 7 is assembled between the proximal side of the mop cover 31 and the proximal panel 1a of the housing 1. The linkage transmission member 7 can be similar to a clutch, which has a disengaged state and an engaged state.

[0140] When the cleaning assembly 3 is in the stowed floor state and the extended floor state, the linkage transmission member 7 is in the disengaged state, and the linkage transmission member 7 does not drive the shielding cover 6, but keeps the shielding cover 6 in the upper part of the mop cover 31 to expose the bottom of the roller mop 32.

[0141] When the cleaning assembly 3 is in the stowed raised state, the linkage transmission member 7 is in the engaged state, which drives the shielding cover 6 to slide from the upper part of the mop cover 31 to the lower part of the mop cover 31 to shield the bottom of the roller mop 32. At this time, since the linkage transmission assembly 7 is in the disengaged state, the shaking or swinging of the roller mop 32 during mopping will not be transmitted to the shielding cover 6 through the linkage transmission assembly 7, avoiding the shielding cover 6 from following the shaking or swinging of the roller mop 32 during mopping.

[0142] That is, when the cleaning assembly 3 is converted from the storage lowered state to the storage raised state, the linkage transmission member 7 causes the shielding cover 6 to slide from the upper portion of the mop cover 31 to the lower portion of the mop cover 31; when the cleaning assembly 3 is converted from the storage raised state to the storage lowered state, the linkage transmission member 7 causes the shielding cover 6 to slide from the lower portion of the mop cover 31 to the upper portion of the mop cover 31; and when the cleaning assembly 3 is converted to the storage lowered state, the linkage transmission member 7 is in the separated state and no longer drives the shielding cover 6, but keeps the shielding cover 6 in the upper portion of the mop cover 31 to expose the bottom of the roller mop 32.

[0143] In one embodiment, as shown in Figures 3-4 、 Figure 8 、 Figures 10-13 and Figure 15 , the linkage transmission member 7 includes a fixed rack 71 connected to the proximal panel 1a, a transmission gear 72 in meshing transmission with the fixed rack 71, and an oscillating member 73 fixedly connected to the transmission gear 72.

[0144] The transmission gear 72 is pivotally connected to the proximal end cover 31a of the mop cover 31, and the fixed rack 71 is vertically arranged on one side of the transmission gear 72.

[0145] The oscillating member 73 is arranged on the outside of the proximal end cover 31a in an oscillating manner and is fixedly connected to the shielding cover 6.

[0146] In this embodiment, the linkage transmission member 7 includes the fixed rack 71, the transmission gear 72, and the oscillating member 73.

[0147] The fixed rack 71 is fixedly connected to the proximal panel 1a and is vertically arranged on the front side of the transmission gear 72, and the side of the fixed rack 71 facing the transmission gear 72 is provided with a plurality of teeth arranged in an up-down interval.

[0148] The transmission gear 72 is installed on the outside of the proximal end cover 31a through a rotating shaft, and the transmission gear 72 can rotate relative to the proximal end cover 31a and the mop cover 31. The transmission gear 72 is in meshing transmission with the fixed rack 71.

[0149] The proximal end cover 31c is arranged on the outside of the transmission gear 72, and the front side thereof is provided with an opening for exposing the transmission gear 72 to mesh with the fixed rack 71.

[0150] The oscillating member 73 is arranged on the outside of the proximal end cover 31a and can oscillate relative to the proximal end cover 31a. One end of the oscillating member 73 is fixedly connected to the transmission gear 72, and the other end is fixedly connected to the proximal end 6a of the shielding cover 6.

[0151] Preferably, the swing member 73 is in a fan shape structure, the transmission gear 72 is connected to the narrower end of the swing member 73, and the longer end of the swing member 73 is fixedly connected to the proximal end 23a of the shielding cover 6.

[0152] Thus arranged, in combination with the Figures 1-5 shown, at this time, the cleaning assembly 3 is in the storage lowered state, the mop cover 31 is in the low position, and the shielding cover 6 is in the upper part of the mop cover 31. When the cleaning assembly 3 is raised to the Figures 6-8 shown, in the process of the cleaning assembly 3 being in the storage lowered state, the mop cover 31 swings from top to bottom, the transmission gear 72 is rotated counterclockwise by the fixed rack 71, thereby driving the shielding cover 6 to swing upward through the swing member 73, and then sliding to the upper part of the mop cover 31.

[0153] Thus arranged, in combination with the Figures 6-8 shown, at this time, the cleaning assembly 3 is in the storage lowered state, the mop cover 31 is in the low position, and the shielding cover 6 is in the upper part of the mop cover 31. When the cleaning assembly 3 is raised to the Figures 1-5 shown, in the process of the cleaning assembly 3 being in the storage lowered state, the mop cover 31 swings from top to bottom, the transmission gear 72 is rotated counterclockwise by the fixed rack 71, thereby driving the shielding cover 6 to swing upward through the swing member 73, and then sliding to the upper part of the mop cover 31.

[0154] In one embodiment, the fixed rack 71 has a preset arc to adapt to the swing trajectory of the transmission gear 72 with the mop cover 31. Preferably, the center of the fixed rack 71 is at the pivot center of the mop cover 31.

[0155] Preferably, the transmission gear 72 is integrally arranged with the swing member 73, which is convenient for processing and forming, has high structural strength, and long service life.

[0156] Preferably, the cross sections of the shielding cover 6 and the mop cover 31 are respectively in circular arc shapes, the central angle of the shielding cover 6 is greater than that of the bottom opening 311 of the mop cover 31. When the shielding cover 6 is in the lower part of the mop cover 31, the shielding cover 6 completely shields the bottom opening 311. That is, the arc length of the shielding cover 6 is greater than the arc length occupied by the bottom opening 311 of the mop cover 31, so that when the shielding cover 6 is in the lower part of the mop cover 31, the shielding cover 6 completely shields the bottom opening 311 and can completely shield the bottom part of the roller mop 22.

[0157] In one embodiment, as Figures 7-8 shown, when the cleaning assembly 3 is in the storage lowered state, the transmission gear 72 is separated from the fixed rack 71, and the transmission gear 72 is located obliquely below the fixed rack 71. When the cleaning assembly 3 swings upward by a preset angle, the transmission gear 72 is engaged with the fixed rack 71.

[0158] In this way, when the cleaning assembly 3 performs the mopping task, the transmission gear 72 is separated from the fixed rack 71, the swing range of the cleaning assembly 3 during mopping is relatively small, the transmission gear 72 cannot be engaged with the fixed rack 71, and the shielding cover 6 cannot swing along with the swing of the cleaning assembly 3 during mopping.

[0159] An embodiment of the present application provides a sweeping robot, which comprises the sweeping and mopping mechanism according to any one of the preceding embodiments. The sweeping and mopping mechanism is arranged at the rear half of the body of the sweeping robot.

[0160] According to the need, the above technical solutions can be combined to achieve the best technical effect.

[0161] The above is only the principle and the preferred embodiment of the present application. It should be noted that, for those skilled in the art, on the basis of the principles of the present application, a number of other variations can also be made, which should also be considered as the protection scope of the present application.
