Description

Technical Field

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

[0002] With the development of social economy and the improvement of people's living standards, cleaning equipment such as cleaning robots have greatly reduced the labor intensity and time spent on housework due to their high cleaning efficiency and convenience, and are becoming more and more popular among users.

[0003] Traditional cleaning robots mainly include cleaning components such as a main brush, a rag, and a side brush. When performing cleaning tasks, the side brush is used to gather dust on the side of the body near the roller brush to facilitate roller brush cleaning. However, existing cleaning robots have the following problems: when the cleaning robot is walking, the side brush is always in contact with the ground, and stains may adhere to the side brush, thereby causing contamination to the cleaning surface. Utility Model Content

[0004] In view of the above problems, the utility model provides a cleaning device, which can flexibly control the position of a cleaning member relative to a surface to be cleaned to avoid secondary contamination of the surface to be cleaned by the cleaning member, and can also improve the adaptability of the cleaning device to the environment.

[0005] The utility model provides a cleaning device, comprising: a machine body; a side brush assembly, the side brush assembly is movably connected to the machine body, the side brush assembly has a cleaning position in contact with a surface to be cleaned, and a lifting position separated from the surface to be cleaned; the side brush assembly comprises a side brush shell and a cleaning member at least partially accommodated in the side brush shell, when the side brush shell and the cleaning member are in a first relative motion state, the side brush assembly is in the cleaning position to clean the surface to be cleaned by the cleaning member; when the side brush shell and the cleaning member are in a second relative motion state, the side brush assembly switches between the cleaning position and the lifting position.

[0006] According to the cleaning device of the utility model, when the side brush housing and the cleaning member are in a first relative motion state, the side brush assembly is in a cleaning position to clean the surface to be cleaned through the cleaning member; when the side brush housing and the cleaning member are in a second relative motion state, the side brush assembly switches between the cleaning position and the lifting position. In this way, the position of the side brush assembly relative to the surface to be cleaned can be flexibly controlled according to the working conditions by simply adjusting the relative motion state of the side brush housing and the cleaning member, so as to avoid contamination of the surface to be cleaned by dirt on the side brush assembly, resulting in low cleaning efficiency, and also improve the adaptability of the cleaning device to the environment, which helps to improve the user experience.

[0007] In some embodiments, when the side brush housing and the cleaning member are in the first motion state, the side brush housing and the cleaning member move synchronously; when the side brush housing and the cleaning member are in the second motion state, the side brush housing and the cleaning member produce relative motion, and the cleaning member switches between the cleaning position and the lifting position under the contact force of the side brush housing.

[0008] In this way, through the relative movement between the side brush housing and the cleaning element, at least a part of the structure of the cleaning element moves toward the inside of the side brush housing, thereby being separated from the surface to be cleaned. The operating principle is relatively simple and easy to implement.

[0009] In some embodiments, the side brush assembly includes a first drive assembly, and the first drive assembly is used to drive the side brush housing and the cleaning element to move synchronously or generate relative motion.

[0010] By providing the first driving assembly, the side brush assembly can be conveniently controlled to switch between the cleaning position and the lifting position, so as to avoid contamination of the surface to be cleaned by the side brush assembly.

[0011] In some embodiments, when the side brush assembly is in the cleaning position, the first drive assembly drives the side brush housing and the cleaning member to move synchronously, and the first drive assembly drives the side brush assembly to clean the surface to be cleaned; when the first drive assembly drives the side brush housing and the cleaning member to produce relative movement, the side brush assembly switches between the cleaning position and the raised position.

[0012] In this way, the motion control method of the first driving component is relatively simple and easy to implement.

[0013] In some embodiments, the side brush housing has a mounting cavity and an extension port communicated with the mounting cavity, the cleaning member is partially disposed in the mounting cavity, and the extension port is suitable for allowing the cleaning member to extend.

[0014] In this way, the matching mode of the side brush housing and the cleaning element is relatively simple and easy to implement.

[0015] In some embodiments, when the side brush housing and the cleaning element produce relative movement, at least one of the extension length of the cleaning element relative to the outside of the side brush housing or the height relative to the surface to be cleaned can change, so that the cleaning element is raised or lowered relative to the surface to be cleaned.

[0016] In this way, the cleaning member can be implemented in various ways, which can better meet the use requirements, and the specific structure of the cleaning member can be flexibly selected according to actual needs.

[0017] In some embodiments, the first drive assembly includes a first motor. When the side brush assembly is in a cleaning position and the first motor rotates in a first direction, the side brush housing and the cleaning member move synchronously, and the cleaning member cleans the surface to be cleaned. When the side brush assembly is in a cleaning position and the first motor rotates in a second direction, the side brush housing and the cleaning member move relative to each other, and the cleaning member is lifted.

[0018] In this way, the side brush assembly can be switched from the first relative motion state to the second relative motion state and from the cleaning position to the raised position only by the first motor, so that the overall structure is relatively simple, easy to implement and low in cost.

[0019] In some embodiments, when the cleaning member is in the raised position and the first motor rotates in a first direction, there is a speed difference between the rotation of the side brush housing and the cleaning member, and the side brush assembly moves to the cleaning position.

[0020] In this way, the side brush assembly can be converted from the raised position to the cleaning position.

[0021] In some embodiments, the first driving assembly includes a stopper and an output shaft, one of which is connected to the cleaning member, and the other of which is connected to the side brush housing, and the stopper is configured to rotate in a first direction.

[0022] In some embodiments, the stop member includes a one-way bearing, the inner ring of the one-way bearing is connected to the cleaning member, the inner ring of the bearing is configured to rotate along a first direction, and the output shaft is connected to the side brush housing so that the side brush housing rotates with the rotation direction of the first motor.

[0023] In this way, the cleaning element and the side brush housing can both rotate synchronously in the first direction driven by the first motor, and the side brush housing can also rotate in the second direction driven by the first motor, thereby generating relative movement with the cleaning element, and the implementation method is relatively simple and low cost.

[0024] In some embodiments, the side brush housing has a connecting shaft, one end of which is located in the mounting cavity and connected to the side brush housing, and the other end extends from the mounting cavity and connected to the output shaft. The connecting shaft is connected to the cleaning member and is suitable for driving the cleaning member to rotate around the connecting shaft.

[0025] By setting the connecting shaft, the side brush assembly and the first driving assembly are connected and matched, and when the first driving assembly drives the connecting shaft to rotate, the connecting shaft can drive the cleaning member to rotate relative to the side brush housing, so as to realize the cleaning member extending from the extension port.

[0026] In some embodiments, the edge side wall of the extension port forms a guide surface, and when the first motor rotates along the second direction, the guide surface abuts against the cleaning member to change the position of the cleaning member relative to the side brush housing.

[0027] In this way, by setting the guide surface, when the side brush housing rotates with the connecting shaft, the side brush housing can press the cleaning element inward, making it easier for the cleaning element to retract into the interior of the side brush housing, and the retraction process is smoother, reducing the jamming phenomenon.

[0028] In some embodiments, side walls on opposite sides of the extension opening extend obliquely relative to the axial direction of the connecting shaft to form at least a portion of the guide surface.

[0029] In this way, when the side brush shell rotates along the second direction relative to the cleaning element, the cleaning element can be retracted along the guide surface into the side brush shell, and the retraction process is relatively smooth, which can minimize the squeezing force of the side brush shell on the cleaning element, thereby reducing the degree of bending deformation of the cleaning element and ensuring the reliability of the cleaning element.

[0030] In some embodiments, at least a portion of the guide surface forms a preset angle with the horizontal direction so that the guide surface extends obliquely upward, and when the cleaning member retracts into the installation cavity, the cleaning member moves along the guide surface to change its height relative to the surface to be cleaned.

[0031] In this way, the cleaning member can be retracted along the guide surface into the side brush housing, and the retraction process is relatively smooth, which can minimize the squeezing force of the side brush housing on the cleaning member, thereby reducing the degree of bending deformation of the cleaning member and ensuring the reliability of the cleaning member.

[0032] In some embodiments, the cleaning member includes: a clutch sleeve, the clutch sleeve is sleeved on the connecting shaft, the stop member is provided on the first driving assembly and sleeved on the outer side of the clutch sleeve to stop the clutch sleeve when the connecting shaft rotates around the second direction; a cleaning strip, the cleaning strips are multiple, and the multiple cleaning strips are arranged at intervals along the circumference of the clutch sleeve, one end of the cleaning strip is connected to the clutch sleeve, and the other end extends from the mounting cavity.

[0033] In this way, the cleaning member and the connecting shaft can be rotated together by the clutch sleeve, and the cleaning member can be stopped by the stopper and the clutch sleeve. The overall matching method is relatively simple and easy to implement.

[0034] In some embodiments, the first drive component has an assembly cavity, the output shaft is located in the assembly cavity, at least part of the structure of the connecting shaft extends into the assembly cavity, and is sleeved on the outside of the output shaft; the stop member is a one-way bearing, and the one-way bearing is fixedly disposed in the assembly cavity.

[0035] In this way, the cooperation between the first drive component and the connecting shaft is relatively simple. Since the stop member is a one-way bearing, it can provide rotational support for the connecting shaft when it rotates in the first direction, and can also stop the cleaning member separately when the connecting shaft rotates in the second direction. The complexity of the overall structure is not increased due to the stopping of the cleaning member, and the cost is low.

[0036] In some embodiments, the first drive assembly further includes: a connecting sleeve, which is embedded between the clutch sleeve and the inner ring of the one-way bearing, and the connecting sleeve is respectively limitedly matched with the inner ring of the bearing and the clutch sleeve along the circumferential direction of the connecting sleeve.

[0037] In this way, when the first drive assembly drives the connecting shaft to rotate in the second direction, the one-way bearing can transmit the stopping force to the clutch sleeve through the bearing inner ring and the connecting sleeve in sequence, which can reduce the wear on the clutch sleeve and ensure its service life.

[0038] In some embodiments, the connecting sleeve is interference fit with the bearing inner ring.

[0039] In this way, the stopping force can be reliably transmitted between the bearing inner ring and the connecting sleeve, and the matching method is simple.

[0040] In some embodiments, the inner hole of the connecting sleeve and the outer wall of the clutch sleeve are both formed into mutually matching polygons.

[0041] In this way, the transmission of the stopping force between the connecting shaft sleeve and the clutch shaft sleeve can be reliably achieved, and the matching method is simple.

[0042] In some embodiments, an extension direction of a projection of the cleaning strip within a reference plane deviates from a radial direction of the connecting shaft, wherein the reference plane is perpendicular to an axis of the connecting shaft.

[0043] The cleaning strip is constructed so that the extension direction of the projection within the reference plane deviates from the radial direction of the connecting axis. Compared with the solution in which the cleaning strip extends radially along the connecting axis, the deformation degree of the cleaning strip can be reduced to ensure that it will not suffer structural damage. At the same time, it also makes it easier for the cleaning strip to converge into the side brush housing to achieve the purpose of separation from the surface to be cleaned.

[0044] In some embodiments, the cleaning strip is connected to the clutch sleeve along one side of its width direction, and a relief notch is provided on the side of the connection between the cleaning strip and the clutch sleeve close to the clutch sleeve, and the relief notch opens circumferentially toward the clutch sleeve.

[0045] By setting the avoidance gap, the extrusion of various parts of the cleaning strip when it is gathered can be reduced, the degree of deformation can be reduced, the service life of the cleaning strip can be extended, and the gathering process can be made smoother.

[0046] In some embodiments, the width of the avoidance gap gradually increases along the circumference and outward direction of the clutch sleeve.

[0047] In this way, the deformability of the cleaning strip can be increased while ensuring the service life of the cleaning strip, making the contraction process smoother.

[0048] In some embodiments, the side walls on opposite sides of the avoidance gap are both constructed as arc surfaces suitable for fitting together.

[0049] This helps to reduce the degree of extrusion deformation of the structures on both sides of the avoidance gap, extend the service life of the cleaning strip, and make the contraction process smoother.

[0050] In some embodiments, the cleaning strip includes: a connecting body connected to the clutch sleeve; and bristles disposed at an end of the connecting body away from the clutch sleeve.

[0051] Thus, the structure of the cleaning strip is relatively simple and easy to manufacture.

[0052] In some embodiments, the connecting body is at least one of thermoplastic polyurethanes (TPU), silicone, and spring steel; and / or the bristles are at least one of nylon and polyvinyl chloride (PVC).

[0053] In this way, the connecting body can have sufficient flexibility and can be more easily retracted into the side brush housing, thereby reducing the risk of damage.

[0054] In some embodiments, the cleaning strip is at least one of acrylonitrile butadiene styrene (ABS) and polypropylene (PP).

[0055] In this way, the connection body can have a certain hardness and structural strength, which helps to ensure the cleaning effect.

[0056] In some embodiments, the cleaning strip and the clutch sleeve are detachably connected; or, the cleaning strip and the clutch sleeve are integrally formed.

[0057] In this way, the convergence force of the cleaning strip can be further reduced, making the switching process of the side brush assembly smoother; further, the cleaning strip forms a preset angle with the rotation direction, which makes it easy to detach the hair adhering to the cleaning strip during operation, thereby avoiding entanglement of the cleaning strip.

[0058] In some embodiments, the height range of the side brush assembly being raised is: 2-15 mm.

[0059] In this way, it can avoid the situation where the height is too small, for example, less than 2 mm, resulting in the distance from the surface to be cleaned being too small, which may cause contact with the surface to be cleaned and cause contamination; it can also avoid the situation where the height is too large, for example, greater than 15 mm, resulting in the side brush assembly occupying too much space in the height direction, resulting in the overall volume of the cleaning equipment being too large, which is not conducive to a lightweight design.

[0060] In some embodiments, the first drive component includes: a transmission component, the transmission component includes a housing and a transmission mechanism, the housing defines the assembly cavity, the transmission mechanism is disposed in the assembly cavity, the output shaft is connected to the transmission mechanism, and the first motor drives the output shaft to rotate through the transmission mechanism to drive the connecting shaft to rotate.

[0061] In this way, the overall structure of the first driving assembly can be relatively simple and easy to implement.

[0062] In some embodiments, the transmission mechanism includes a plurality of gears meshing with each other, and the output shaft is connected to a final gear among the plurality of gears.

[0063] By providing a plurality of gears, the size and number of teeth of the gears can be flexibly adjusted, thereby adjusting the rotation speed and rotation direction of the output shaft. In addition, the structure of the transmission mechanism is relatively simple and easy to implement.

[0064] In some embodiments, the side brush housing includes: a side brush base and a side brush top cover, the side brush base and the side brush top cover are connected to each other and jointly define the installation cavity, one end of the connecting shaft is connected to the side brush base, and the other end passes through the side brush top cover and is connected to the first drive assembly.

[0065] In this way, connecting the connecting shaft to the side brush base can drive the side brush housing to rotate in the first direction and in the second direction. At the same time, it is convenient to connect the cleaning bar to the connecting shaft to realize the rotation of the side brush housing relative to the cleaning bar in the second direction.

[0066] In some embodiments, the first drive assembly is adapted to drive the side brush assembly to perform a lifting motion to switch between the cleaning position and the raised position.

[0067] In this way, the coordination between the first drive assembly and the side brush assembly can be further simplified.

[0068] In some embodiments, the cleaning device further comprises a second driving assembly, wherein the second driving assembly is connected to the connecting shaft and is adapted to drive the connecting shaft to rotate so that the cleaning member performs a cleaning operation.

[0069] In this way, the control method of the first driving component and the second driving component can be further simplified.

[0070] In some embodiments, the cleaning device also includes: a swing arm rotatably connected to the body, the side brush assembly is arranged on the swing arm to follow the movement of the swing arm, and the swing arm moves relative to the body between a retracted position and an outward swing position, wherein when the swing arm is in the outward swing position, the range of the side brush assembly exceeding the body is greater than the range of the side brush assembly exceeding the body when the swing arm is in the retracted position.

[0071] In this way, the side brush assembly can be controlled to move to the side of the machine body and a certain distance away from the machine body by controlling the swing of the swing arm. In this way, the cleaning range of the cleaning device can be larger and it can adapt to more complex cleaning conditions.

[0072] In some embodiments, when the swing arm is in the retracted position, the first drive assembly drives the side brush assembly to switch between the cleaning position and the raised position, and at least a portion of the first drive assembly is disposed on the swing arm.

[0073] In this way, the structure of the swing arm and the coordination with the machine body are relatively simple and easy to implement.

[0074] In some embodiments, the cleaning device also includes a third drive assembly, which is disposed on the body to drive the swing arm to move between a retracted position and an outward swing position; when the side brush assembly is in the cleaning position, the third drive assembly drives the swing arm side brush assembly to move between the retracted position and the outward swing position.

[0075] Like this, in any position of retracted position and outward swing position, the side brush assembly can carry out cleaning task.

[0076] In some embodiments, the cleaning device has a sweeping and mopping mode and a cleaning mode. When the cleaning device is switched from the sweeping and mopping mode to the cleaning mode, the first driving component drives the cleaning device to switch from the cleaning position to the lifting position.

[0077] In this way, the cleaning equipment has more working modes, can adapt to more and more complex working conditions, and improve the user experience.

[0078] In this way, when the cleaning device is in different working modes, the first driving assembly can drive the side brush assembly to change position, thereby improving the user experience and ensuring the cleaning effect.

[0079] In some embodiments, when the side brush assembly is performing a cleaning task, the side brush assembly is in a cleaning position; when a preset condition occurs when the side brush assembly is performing a cleaning task, the first drive assembly drives the side brush assembly to switch from the cleaning position to the raised position; the preset condition includes at least one of the following: when the cleaning device is performing carpet area cleaning; when the cleaning device returns to a base station; when the cleaning device is switched to a work task that does not require cleaning; when the cleaning device needs to cross an obstacle; when the cleaning device is creating a map; when there are wet stains on the cleaning path of the cleaning device.

[0080] Thus, in the above-mentioned cases, the side brush assembly can be switched from the cleaning position to the lifting position under the drive of the first driving assembly to prevent the side brush assembly from contaminating the surface to be cleaned. BRIEF DESCRIPTION OF THE DRAWINGS

[0103] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0104] With the development of social economy and the improvement of people's living standards, cleaning equipment such as cleaning robots have greatly reduced the labor intensity and time spent on housework due to their high cleaning efficiency and convenience, and are becoming more and more popular among users. Traditional cleaning robots mainly include cleaning components such as a main brush, a rag, and a side brush. When performing cleaning tasks, the side brush is used to gather dust on the side of the body to the vicinity of the roller brush to facilitate roller brush cleaning. However, existing cleaning robots have the following problems: when the cleaning robot is walking, the side brush is always in contact with the ground, and stains may adhere to the side brush, thereby causing contamination to the surface to be cleaned.

[0105] In view of this, an embodiment of the utility model provides a cleaning device that can flexibly control the position of the cleaning component relative to the surface to be cleaned to avoid secondary contamination of the surface to be cleaned by the cleaning component, resulting in low cleaning efficiency. It can also improve the adaptability of the cleaning device to the environment, which helps to improve the user experience.

[0106] Reference below Figure 1-Figure 8 A cleaning device 100 according to an embodiment of the present invention is described.

[0107] Specifically, the cleaning device 100 of this embodiment may be a sweeping robot, or may be other devices. The cleaning device 100 includes a body 40 and a cleaning component.

[0108] Among them, the body 40 is suitable for walking along the ground, tabletop, carpet and other surfaces to be cleaned. For example, the body 40 can be provided with walking wheels, and the body 40 walks on the surface to be cleaned by the walking wheels. At the same time, the walking wheels can also keep the body 40 at a certain height, so as to facilitate the installation of other devices at the bottom of the body 40, such as a cleaning component. The cleaning component of the cleaning device 100 exemplarily includes a side brush component 10, a mop component and a roller brush component. The side brush component 10 is mainly used to wave dirt such as dust to the vicinity of the roller brush so that the roller brush can perform dust suction treatment. The mop component can wet clean the floor by wet mopping.

[0109] The side brush assembly 10 can be arranged at the edge of the machine body 40. The side brush assembly 10 is movably connected to the machine body 40, and when the machine body 40 moves along the surface to be cleaned, the side brush assembly 10 cleans the surface to be cleaned.

[0110] The side brush assembly 10 has a cleaning position and a lifting position, wherein in the cleaning position, the side brush assembly 10 contacts the surface to be cleaned to clean the surface to be cleaned, and in the lifting position, the side brush assembly 10 is separated from the surface to be cleaned to avoid secondary contamination of the surface to be cleaned by dirt on the side brush assembly 10.

[0111] For example, when the cleaning device 100 moves to a floor with liquid stains or sticky stains, the side brush assembly 10 can be controlled to switch from a cleaning position to a raised position to prevent the side brush assembly 10 from contacting the stains and carrying the stains to other locations on the floor, such as a cleaned location, thereby preventing secondary contamination of the floor; alternatively, when the side brush assembly 10 has finished cleaning the cleaned floor and there is a lot of dirt attached to the side brush assembly 10, the side brush assembly 10 can be controlled to switch from a cleaning position to a raised position to prevent the side brush assembly 10 from contacting the surface to be cleaned, thereby preventing secondary contamination of the floor.

[0112] The side brush assembly 10 further includes a cleaning member 11 and a side brush housing 12 . The cleaning member 11 is at least partially accommodated in the side brush housing 12 . The side brush housing 12 can provide installation support for the cleaning member 11 .

[0113] When the side brush housing 12 and the cleaning member 11 are in a first relative motion state, the side brush assembly 10 is in a cleaning position to clean the surface to be cleaned by the cleaning member 11; when the side brush housing 12 and the cleaning member 11 are in a second relative motion state, the side brush assembly 10 switches between the cleaning position and the raised position. For example, the first relative motion state may be that the cleaning member 11 and the side brush housing 12 rotate synchronously, and the second relative motion state may be that one of the cleaning member 11 and the side brush housing 12 rotates relative to the other.

[0114] According to the cleaning device 100 of the embodiment of the utility model, when the side brush housing 12 and the cleaning member 11 are in a first relative motion state, the side brush assembly 10 is in a cleaning position to clean the surface to be cleaned through the cleaning member 11; when the side brush housing 12 and the cleaning member 11 are in a second relative motion state, the side brush assembly 10 switches between the cleaning position and the lifting position. In this way, the position of the side brush assembly 10 relative to the surface to be cleaned can be flexibly controlled according to the working conditions by simply adjusting the relative motion state of the side brush housing 12 and the cleaning member 11, so as to avoid contamination of the surface to be cleaned by dirt on the side brush assembly 10, resulting in low cleaning efficiency, and also improve the adaptability of the cleaning device 100 to the environment, which helps to improve the user experience.

[0115] In some embodiments, when the side brush housing 12 and the cleaning member 11 are in a first motion state, the side brush housing 12 and the cleaning member 11 move synchronously, that is, when the side brush assembly 10 cleans the surface to be cleaned, the side brush housing 12 and the cleaning member 11 rotate synchronously. When the side brush housing 12 and the cleaning member 11 are in a second motion state, the side brush housing 12 and the cleaning member 11 produce relative motion, and the cleaning member 11 switches between the cleaning position and the lifting position under the contact force of the side brush housing 12. In this way, through the relative motion between the side brush housing 12 and the cleaning member 11, at least part of the structure of the cleaning member 11 moves toward the inside of the side brush housing 12, thereby separating from the surface to be cleaned. The action principle is relatively simple and easy to implement.

[0116] When the side brush housing 12 and the cleaning member 11 are in the second motion state, the side brush housing 12 and the cleaning member 11 generate relative motion, and the relative motion is a rotational relative motion, for example, the side brush housing 12 generates a rotational motion relative to the cleaning member 11, or the cleaning member 11 generates a relative motion relative to the side brush housing 12. In some embodiments, when the side brush housing 12 and the cleaning member 11 generate relative motion, the side brush housing 12 and the cleaning member 11 generate a circumferential relative displacement and an axial relative displacement.

[0117] In some embodiments, reference Figure 1 and Figure 2 The side brush assembly 10 includes a first drive assembly 20, which can be in transmission cooperation with the side brush assembly 10, and is used to drive the side brush housing 12 and the cleaning member 11 to move synchronously and / or to generate relative movement. By setting the first drive assembly 20, it is convenient to control the side brush assembly 10 to switch between the cleaning position and the lifting position, so as to avoid the side brush assembly 10 from causing contamination to the surface to be cleaned.

[0118] In some embodiments, when the side brush assembly 10 is in the cleaning position, the first drive assembly 20 drives the side brush housing 12 and the cleaning member 11 to move synchronously, so that the first drive assembly 20 can drive the side brush assembly 10 to clean the surface to be cleaned. When the first drive assembly 20 drives the side brush housing 12 and the cleaning member 11 to produce relative motion, the side brush assembly 10 can be switched between the cleaning position and the lifting position. In this way, the motion control method of the first drive assembly 20 is relatively simple and easy to implement.

[0119] In some embodiments, reference Figure 3 and Figure 4The side brush housing 12 can be in a disc, a cylinder or other shapes. The side brush housing 12 has a mounting cavity 121 and a projection opening 122. The projection opening 122 is connected to the mounting cavity 121. The projection opening 122 can be arranged on the side wall or the bottom wall of the side brush housing 12. The cleaning member 11 is partially arranged in the mounting cavity 121. The projection opening 122 is for the cleaning member 11 to extend out. In this way, the coordination between the side brush housing 12 and the cleaning member 11 is relatively simple and easy to implement. In addition, through the structural combination of the cleaning member and the side brush housing, the space required for the side brush assembly can be saved. The travel required for the side brush assembly in the height direction is small, so the height space occupied by the side brush assembly can be reduced, which is conducive to the lightweight design of the cleaning equipment.

[0120] In some embodiments, reference Figure 1 as well as Figure 3 and Figure 4 , the cleaning member 11 produces a relative motion state relative to the side brush housing 12, that is, when the two are in the second relative motion state, at least one of the height of the cleaning member 11 relative to the surface to be cleaned and the extension length of the cleaning member 11 relative to the outside of the side brush housing 12 can be changed, so that the cleaning member 11 is lifted or lowered relative to the surface to be cleaned.

[0121] In other words, in the present embodiment, only the height of the cleaning member 11 relative to the surface to be cleaned can be controlled, such as controlling the cleaning member 11 to rise and fall, so as to make the cleaning member 11 contact or separate from the surface to be cleaned; or, only the change in the extension length of the cleaning member 11 can be controlled, for example, the cleaning member 11 is constructed to contact with the surface to be cleaned when in an expanded state, and to be separated from the surface to be cleaned when in any of a contracted state, a bent state, and a deformed state; or, the cleaning member 11 can be made to contact or separate from the surface to be cleaned by simultaneously controlling the change in the height of the cleaning member 11 relative to the surface to be cleaned and the change in the extension length of the cleaning member 11.

[0122] For example, the cleaning member 11 can rotate relative to the side brush housing 12 to adjust the angular position of the cleaning member 11 in the circumferential direction, or the cleaning member 11 can be extended relative to the side brush housing 12 by moving along the extension opening 122 to adjust the length of the portion of the cleaning member 11 extending from the side brush housing 12, thereby achieving the purpose of changing at least one of the height of the cleaning member 11 relative to the surface to be cleaned and the extension length of the cleaning member 11. In this way, the side brush housing 12 can be used to provide support and accommodation for the relative position change of the cleaning member 11, so as to better achieve the purpose of adjusting the distance between the cleaning member 11 and the surface to be cleaned.

[0123] In this way, the cleaning member 11 can be implemented in various ways and can better meet the usage requirements. In addition, by changing the length of the portion of the cleaning member extending out of the side brush housing to affect the height of the cleaning member from the ground, the space required to be occupied by the side brush assembly in the height direction can be reduced, the axial space of the side brush assembly can be saved, and the cleaning equipment can flexibly set the position of the side brush assembly. The specific structure of the cleaning member 11 can be flexibly selected according to actual needs.

[0124] In some embodiments, reference Figure 1 and Figure 2 , bristles 115 are planted on the cleaning member 11, and the cleaning member 11 cleans the surface to be cleaned through the bristles 115. The cleaning member 11 is constructed to move and contact with the surface to be cleaned to clean the surface to be cleaned, wherein the cleaning member 11 and the surface to be cleaned can be in contact or separated. In other words, in this embodiment, the side brush assembly 10 is switched to the raised position mainly by controlling the cleaning member 11 to separate from the surface to be cleaned, and the side brush assembly 10 is switched to the cleaning position by controlling the cleaning member 11 to contact with the surface to be cleaned. In this way, it is possible to avoid secondary contamination of the surface to be cleaned by the cleaning member 11 of the side brush device, and it is easy to implement.

[0125] In some embodiments, the first drive assembly 20 includes a first motor. When the side brush assembly 10 is in the cleaning position and the first motor rotates in the first direction, the side brush housing 12 and the cleaning member 11 move synchronously, and the cleaning member 11 cleans the surface to be cleaned. When the side brush assembly 10 is in the cleaning position and the first motor rotates in the second direction, the side brush housing 12 and the cleaning member 11 move relative to each other, and the cleaning member 11 is lifted. In other words, the first motor can rotate in both directions, so that the side brush assembly 10 can be switched from the first relative motion state to the second relative motion state, and from the cleaning position to the lifted position only by the first motor, so that the overall structure is relatively simple, easy to implement and low in cost.

[0126] When the cleaning member 11 is in the raised position and the first motor rotates in the first direction, the side brush housing 12 and the cleaning member 11 rotate at a differential speed, so that the side brush assembly 10 moves to the cleaning position. In this way, the side brush assembly 10 can be switched from the raised position to the cleaning position.

[0127] In this way, when the first drive component drives the side brush housing 12 and the cleaning member 11 to move synchronously, the first drive component can drive the cleaning member to perform cleaning work in the cleaning position; when the first drive component drives the side brush housing 12 and the cleaning member 11 to produce relative movement, the side brush assembly can switch between the cleaning position and the lifting position, that is, the cleaning work and lifting action of the side brush assembly can be achieved only by the first drive component, which further simplifies the structural design of the side brush assembly and helps to reduce the manufacturing cost of the cleaning equipment.

[0128] In some embodiments, one of the side brush housing 12 and the cleaning member 11 is configured to rotate in one direction driven by the first motor. When the first motor drives the side brush assembly 10 to rotate in a first direction, the cleaning member 11 and the side brush housing 12 rotate synchronously; when the first motor drives the side brush assembly 10 to rotate in a second direction, one of the cleaning member 11 and the side brush housing 12 rotates relative to the other, so that the side brush assembly reaches the raised position.

[0129] In some embodiments, the first driving assembly 20 includes a stopper 14 and an output shaft 23, one of which is connected to the cleaning member 11, and the other is connected to the side brush housing 12, and the stopper 14 is configured to rotate in a first direction, for example, the stopper 14 may be connected to the cleaning member 11, and the output shaft 23 may be connected to the side brush housing 12; or, the stopper 14 may be connected to the side brush housing 12, and the output shaft 23 may be connected to the stopper 14. In this way, when the first driving assembly 20 is driven in the first direction, the stopper 14 and the output shaft 23 rotate in the first direction, so that the side brush housing 12 and the cleaning member 11 can move synchronously; when the first driving assembly 20 is driven in the second direction, the output shaft 23 rotates in the second direction, and the stopper 14 does not rotate, so that the side brush housing 12 and the cleaning member 11 can generate relative motion.

[0130] In a specific embodiment, the stop member 14 includes a one-way bearing. Since the inner ring of the one-way bearing can only rotate in one direction relative to its outer ring, the one-way bearing can be used as a stop member, wherein the inner ring of the one-way bearing is connected to the cleaning member 11, and the inner ring of the bearing is configured to rotate in a first direction. The output shaft 23 rotates under the drive of the first motor, and the output shaft 23 is connected to the side brush housing 12 so that the side brush housing 12 rotates with the rotation direction of the first motor. In this way, the cleaning member 11 and the side brush housing 12 can both rotate synchronously in the first direction under the drive of the first motor, and the side brush housing 12 can also rotate in the second direction under the drive of the first motor, thereby generating relative motion with the cleaning member 11, and the implementation method is relatively simple and the cost is low.

[0131] In other embodiments, the connection relationship between the one-way bearing and the output shaft 23 can also be exchanged. For example, the inner ring of the one-way bearing is connected to the side brush housing 12, and the output shaft 23 is connected to the cleaning strip 11, and the relative motion state of the side brush assembly 10 also changes accordingly.

[0132] In addition to the one-way bearing described above, the stopper 14 may also be of other structures. For example, the stopper 14 may be constructed so that when the cleaning member 11 rotates in the second direction, the stopper 14 and the cleaning member 11 interfere with each other in the rotation direction; or the stopper 14 may be constructed so that it can only rotate in the first direction but cannot rotate in the second direction. The structure of the stopper 14 may be reasonably designed according to actual needs, such as using a one-way ratchet, a one-way gear rack, or the like.

[0133] In this way, by setting a stopper, one of the cleaning member or the side brush housing can rotate unidirectionally, and the other can produce bidirectional rotation following the output shaft, thereby realizing relative movement between the side brush housing and the cleaning member. The structure is simple and easy to implement.

[0134] In some embodiments, reference Figure 1 and Figure 2 , the side brush assembly 10 may further include a connecting shaft 13. Specifically, one end of the connecting shaft 13 (e.g., the lower end of the connecting shaft 13) is located in the installation cavity 121 and connected to the side brush housing 12, and the other end (e.g., the upper end of the connecting shaft 13) extends from the installation cavity 121 and is connected to the output shaft 23 of the first drive assembly 20. The connecting shaft 13 is connected to the cleaning member 11 and is suitable for driving the cleaning member 11 to rotate around the connecting shaft 13. By providing the connecting shaft 13, it is convenient for the side brush assembly 10 and the first drive assembly 20 to be connected and matched, and when the first drive assembly 20 drives the connecting shaft 13 to rotate, the connecting shaft 13 can drive the cleaning member 11 to rotate relative to the side brush housing 12, so as to realize that the cleaning member 11 is extended from the extension port 122.

[0135] In some embodiments, in combination Figure 1 and Figure 2 The edge side wall of the extension opening 122 of the side brush housing 12 forms a guide surface 123. When the first motor rotates in the second direction, the guide surface 123 abuts against the cleaning member 11, and the cleaning member 11 slides relative to the guide surface 123 to change the position of the cleaning member 11 relative to the side brush housing 12. In this way, by providing the guide surface 123, when the side brush housing 12 rotates with the connecting shaft 13, the side brush housing 12 can press the cleaning member 11 inward, so that the cleaning member 11 can be more easily retracted into the inside of the side brush housing 12, and the retraction process is smoother, reducing the jamming phenomenon.

[0136] In some embodiments, the side walls on opposite sides of the extension opening 122 extend obliquely relative to the axial direction of the connecting shaft 13 to form at least part of the guide surface 123. For example, the side walls on opposite sides of the extension opening 122 along the circumference of the connecting shaft 13 extend obliquely relative to the axial direction of the connecting shaft 13 to form the guide surface 123. In this way, when the side brush housing 12 rotates relative to the cleaning member 11 in the second direction, the cleaning member 11 can be retracted into the side brush housing 12 along the guide surface 123, and the retraction process is relatively smooth, which can minimize the squeezing force of the side brush housing 12 on the cleaning member 11, thereby reducing the degree of bending deformation of the cleaning member 11 and ensuring the reliability of the cleaning member 11.

[0137] In some embodiments, at least part of the guide surface 123 is at a preset angle with the horizontal direction, so that the guide surface 123 extends obliquely upward, and when the cleaning member 11 retracts into the installation cavity 121, the cleaning member 11 moves along the guide surface 123 to change the height relative to the cleaning surface. In this way, the cleaning member 11 can be retracted into the side brush housing 12 along the guide surface 123, and the retraction process is relatively smooth, which can minimize the squeezing force of the side brush housing 12 on the cleaning member 11, thereby reducing the degree of bending deformation of the cleaning member 11 and ensuring the reliability of the cleaning member 11.

[0138] It can be understood that the effect of the guide surface 123 on the cleaning member 11 realizes the change of the angle of the cleaning member 11 relative to the surface to be cleaned, and the extension length of the cleaning member 11 outside the side brush housing 12 is changed by the retraction of the cleaning member 11 into the mounting cavity 121. In summary, by changing the angle and extension length of the cleaning member 11, the cleaning member 11 can be effectively controlled to switch from the cleaning position to the lifting position, so as to achieve separation from the surface to be cleaned, thereby avoiding secondary contamination of the surface to be cleaned. In addition, by setting the guide surface 123 at a preset angle with the horizontal direction, when the cleaning strip 112 retracts into the side brush housing 12, the side brush assembly 10 has a lifting effect based on the guide surface 123, thereby further enhancing the height of the cleaning strip 112 from the ground; and the way of setting the guide surface 123 is simple in structure and easy to implement, and there is no need to increase the power element to drive the change of the height of the side brush assembly 10 from the ground, thereby further simplifying the structural design of the side brush assembly 10.

[0139] In some embodiments, in combination Figure 1 , Figure 2 and Figure 6The cleaning member 11 may include a clutch sleeve 111 and a cleaning strip 112. Specifically, the clutch sleeve 111 may be sleeved on the connecting shaft 13, and the stopper 14 is provided on the first driving assembly 20 and sleeved on the outer side of the clutch sleeve 111, so that when the connecting shaft 13 rotates around the second direction, the stopper 14 may stop the clutch sleeve 111. There are a plurality of cleaning strips 112, and the cleaning strips 112 are used to clean the surface to be cleaned. The plurality of cleaning strips 112 are arranged at intervals along the circumference of the clutch sleeve 111, and one end of the cleaning strip 112 is connected to the clutch sleeve 111, and the other end extends from the extension port 122.

[0140] In this way, the cleaning member 11 can be rotated with the connecting shaft 13 through the clutch sleeve 111, and the cleaning member 11 can be stopped through the cooperation of the stopper 14 and the clutch sleeve 111. The overall cooperation method is relatively simple and easy to implement, and the clutch sleeve is sleeved on the connecting shaft, and the stopper is sleeved on the outside of the clutch sleeve. The sleeve relationship in the circumferential direction is conducive to the cooperation between the structures on the one hand, and on the other hand, it is conducive to the extreme compression of the axial space required by the side brush assembly, thereby reducing the occupation of the height space of the cleaning equipment and reducing the height of the cleaning equipment, so that the cleaning equipment has better accessibility to low areas.

[0141] In some embodiments, in combination Figure 1 and Figure 2 The first driving assembly 20 has an assembly cavity 211, in which a rotatable output shaft 23 is arranged, at least part of the structure of the connecting shaft 13 extends into the assembly cavity 211, and the connecting shaft 13 can be sleeved on the outside of the output shaft 23. The stopper 14 is a one-way bearing, which is fixedly arranged in the assembly cavity 211. Moreover, since the clutch sleeve 111 of the cleaning member 11 is sleeved on the outside of the connecting shaft 13, the one-way bearing can be matched with the clutch sleeve 111. Of course, this embodiment does not limit this, and the stopper 14 can also be other one-way stop elements. In this way, the axial space required for the side brush assembly can be reduced, which is conducive to reducing the height of the cleaning device.

[0142] In this way, the cooperation between the first drive component 20 and the connecting shaft 13 is relatively simple. Since the stop member 14 is a one-way bearing, it can provide rotation support for the connecting shaft 13 when it rotates in the first direction, and can also stop the cleaning member 11 separately when the connecting shaft 13 rotates in the second direction. The complexity of the overall structure is not increased due to the stopping of the cleaning member 11, and the cost is low.

[0143] In some embodiments, reference Figure 1The inner side of the connecting shaft 13 has a fixed end plate, and a threaded connecting hole is provided on the fixed end plate. The inner wall of the output shaft 23 is provided with a threaded matching hole. After the connecting shaft sleeve 24 is arranged on the outer side of the output shaft 23, the connecting shaft 13 and the output shaft 23 are fastened and connected by threaded fasteners 15 passing through the threaded connecting hole and the threaded matching hole in turn. In this way, the connection method of the connecting shaft 13 and the output shaft 23 is simple and reliable, which can ensure the transmission of power.

[0144] In some embodiments, in combination Figure 1 and Figure 2 , the first drive assembly 20 may further include a connecting sleeve 24. Specifically, the connecting sleeve 24 is embedded between the clutch sleeve 111 and the inner ring of the one-way bearing, and the connecting sleeve 24 is respectively matched with the inner ring of the bearing and the clutch sleeve 111 along the circumferential limit of the connecting sleeve 24, so that when the first drive assembly 20 drives the connecting shaft 13 to rotate along the second direction, the one-way bearing can sequentially transmit the stopping force to the clutch sleeve 111 through the inner ring of the bearing and the connecting sleeve 24, which can reduce the wear on the clutch sleeve 111 and ensure its service life.

[0145] In some embodiments, the connecting sleeve 24 is interference fit with the inner ring of the bearing, so that the stopping force can be reliably transferred between the inner ring of the bearing and the connecting sleeve 24, and the fitting method is simple.

[0146] In some embodiments, the inner hole of the connecting sleeve 24 and the outer wall of the clutch sleeve 111 are both formed into mutually adapted polygons. For example, the inner hole of the connecting sleeve 24 and the outer wall of the clutch sleeve 111 can be quadrilateral, hexagonal or octagonal, so that the stopping force can be reliably transmitted between the connecting sleeve 24 and the clutch sleeve 111, and the matching method is simple. At the same time, when the side brush housing and the cleaning member move synchronously, the side brush housing and the cleaning member are prevented from slipping, which affects the cleaning experience.

[0147] In some embodiments, the extension direction of the projection of the cleaning strip 112 in the reference plane deviates from the radial direction of the connecting shaft 13, wherein the reference plane is perpendicular to the axis of the connecting shaft 13, that is, the cleaning strip 112 is biased toward one side of the connecting shaft 13 in the circumferential direction relative to the axis of the connecting shaft 13. Since the side brush housing 12 exerts a circumferential squeezing force on the cleaning strip 112 when the side brush housing 12 rotates relative to the cleaning member 11, and in this embodiment, the extension direction of the projection of the cleaning strip 112 in the reference plane deviates from the radial direction of the connecting shaft 13, compared with the solution in which the cleaning strip 112 extends in the radial direction of the connecting shaft 13, the deformation degree of the cleaning strip 112 can be reduced to ensure that it will not be structurally damaged, and at the same time, it is easier for the cleaning strip 112 to converge into the side brush housing 12 to achieve the purpose of separation from the surface to be cleaned.

[0148] In some embodiments, reference Figure 3-Figure 6The extension lines of the multiple cleaning strips 112 are all tangent to the same circle, the center of which passes through the central axis of the side brush assembly 10. In this way, the convergence force of the cleaning strips 112 can be further reduced, making the switching process of the side brush assembly 10 smoother. In this way, during the working process, the cleaning strips 112 and the rotation direction of the side brush assembly 10 during cleaning are at an angle of approximately 45°. During the working process of the side brush assembly 10, the hair adhering to the cleaning strips 112 will be detached downward, thereby at least partially achieving the effect of preventing the side brush assembly 10 from tangling hair.

[0149] In some embodiments, the height range of the side brush assembly 10 is 2-15 mm. In other words, the distance between the bottom end of the cleaning member 11 and the surface to be cleaned is 2-15 mm. For example, the height of the side brush assembly 10 can be 2 mm, 4 mm, 6 mm, 8 mm, 10 mm, 12 mm or 15 mm. Of course, the utility model does not limit this. The lifting height of the side brush assembly 10 can be reasonably selected within the above range according to actual needs. In this way, it is possible to avoid the situation where the height is too small, for example, less than 2 mm, and the distance from the surface to be cleaned is too small, which may lead to contact with the surface to be cleaned and cause contamination, especially when the cleaning surface is not flat enough, the cleaning member may contact with the cleaning surface to cause contamination; in addition, it is possible to avoid the situation where the height is too large, for example, greater than 15 mm, which may lead to the side brush assembly 10 occupying too much space in the height direction. For example, when the cleaning device is performing cleaning work, there is a height from the ground between the chassis of the cleaning device and the cleaning surface, and the height from the ground is exemplarily not more than 15 mm, so as to ensure good walking performance and cleaning performance of the cleaning device. By setting the height range of the side brush assembly to not more than 15 mm, the cleaning device will not increase its own height due to the lifting height of the side brush assembly, thereby causing the overall volume of the cleaning device 100 to be too large, which is not conducive to a lightweight design.

[0150] In some embodiments, reference Figure 6 The cleaning strip 112 is connected to the clutch sleeve 111 on one side along its width direction, and an avoidance notch 113 is provided on the side of the connection between the cleaning strip 112 and the clutch sleeve 111, and the avoidance notch 113 faces the circumferential opening of the clutch sleeve 111. By setting the avoidance notch 113, when the cleaning strip 112 is retracted into the side brush housing 12, the cleaning strip 112 can be attached to the clutch sleeve toward the avoidance notch 113, which can reduce the extrusion of various parts of the cleaning strip 112 when it is contracted, reduce the degree of deformation, extend the service life of the cleaning strip 112, and make the contraction process smoother.

[0151] In some embodiments, the width of the avoidance gap 113 gradually increases along the circumferential and outward direction of the clutch sleeve 111. In this way, the deformability of the cleaning strip 112 can be increased while ensuring the service life of the cleaning strip 112, making the contraction process smoother.

[0152] In some embodiments, the side walls on both sides of the avoidance gap 113 are constructed as arc surfaces suitable for fitting together. This helps to reduce the degree of extrusion deformation of the structures on both sides of the avoidance gap 113, extend the service life of the cleaning strip 112, and make the contraction process smoother.

[0153] In some embodiments, reference Figure 2-Figure 6 The cleaning strip 112 may include a connecting body 114 and bristles 115. Specifically, the connecting body 114 may be in a strip shape, the connecting body 114 is connected to the clutch sleeve 111, the bristles 115 are arranged at one end of the connecting body 114 away from the clutch sleeve 111, the bristles 115 are used to clean the surface to be cleaned, the bristles 115 may be attached to the connecting body 114, or the bristles 115 and the connecting body 114 may be integrally formed. In this way, the structure of the cleaning strip 112 is relatively simple and easy to manufacture.

[0154] In some embodiments, the connecting body 114 is at least one of TPU, silicone, and spring steel; and / or the bristles 115 are at least one of nylon and PVC. In this way, the connecting body 114 can be sufficiently flexible and more easily gathered in the side brush housing 12, reducing the risk of damage.

[0155] In some embodiments, the cleaning strip 112 is at least one of ABS and PP, so that the connecting body 114 can have a certain hardness and structural strength, which helps to ensure the cleaning effect.

[0156] In some embodiments, the cleaning strip 112 is detachably connected to the clutch sleeve 111, for example, the cleaning strip 112 can be clamped on the clutch sleeve 111, or connected in other ways. In this way, when the cleaning strip 112 is damaged or fails, only the cleaning strip 112 can be replaced to reduce maintenance costs.

[0157] Alternatively, in other embodiments, the cleaning strip 112 is integrally formed with the clutch sleeve 111, for example, the cleaning strip 112 can be integrally formed with the clutch sleeve 111 through a rubber encapsulation process. In this way, the connection strength between the cleaning strip 112 and the clutch sleeve 111 can be ensured to ensure that the cleaning strip 112 and the clutch sleeve 111 move synchronously.

[0158] In some embodiments, the first drive assembly 20 may further include a transmission assembly. Specifically, the first motor may be fixedly disposed on the machine body 40, the transmission assembly may include a housing 21 and a transmission mechanism 22, the housing 21 defines an assembly cavity 211, the transmission mechanism 22 is disposed in the assembly cavity 211, the output shaft 23 is connected to the transmission mechanism 22, the first motor drives the output shaft 23 to rotate through the transmission mechanism 22, so as to drive the connecting shaft 13 to rotate, so that the overall structure of the first drive assembly 20 is relatively simple and easy to implement.

[0159] In some embodiments, reference Figure 1 The transmission mechanism 22 includes a plurality of gears meshing with each other, and the specific number of gears and the transmission ratio can be reasonably set according to actual needs. The output shaft 23 is connected to the final gear among the plurality of gears. For example, the output shaft 23 and the final gear can be an integral structure, or the output shaft 23 and the final gear can be two independent parts connected mechanically. By setting a plurality of gears, the size and number of teeth of the gears can be flexibly adjusted, thereby adjusting the rotation speed and rotation direction of the output shaft 23, and the structure of the transmission mechanism 22 is relatively simple and easy to implement.

[0160] In some embodiments, in combination Figure 1 and Figure 2 The side brush housing 12 may include a side brush base 124 and a side brush top cover 125, which are connected to each other and define a mounting cavity 121 together. One end of the connecting shaft 13 is connected to the side brush base 124, and the other end passes through the side brush top cover 125 and is connected to the first driving assembly 20. For example, the side brush base 124 and the side brush top cover 125

[0161] In this way, connecting the connecting shaft 13 with the side brush base 124 can drive the side brush housing 12 to rotate in the first direction and the second direction. At the same time, it is convenient to connect the cleaning strip 112 with the connecting shaft 13 to realize the rotation of the side brush housing 12 relative to the cleaning strip 112 in the second direction.

[0162] In some embodiments, the side brush base 124 and the side brush top cover 125 can both be metal parts. In this case, the side brush base 124 and the side brush top cover 125 can be connected to each other by welding methods such as ultrasonic welding and thermal welding, or the side brush base 124 and the side brush top cover 125 can also be connected by adhesive, for example, by UV glue. In this way, the connection between the side brush bottom cover and the side brush top cover 125 is stable and reliable, which is conducive to better realizing its function, and the connection method is relatively simple and easy to implement.

[0163] In some embodiments, the first drive assembly 20 is suitable for driving the side brush assembly 10 to perform lifting motion to switch between the cleaning position and the raised position. That is to say, in this embodiment, the first drive assembly 20 can drive the side brush assembly 10, that is, the side brush device as a whole to perform lifting and lowering to adjust the distance between the side brush assembly 10 and the surface to be cleaned. For example, the first drive assembly 20 drives the side brush assembly 10 to descend so that the side brush assembly 10 reaches the cleaning position, and the second drive assembly drives the side brush assembly 10 to rise so that the side brush assembly 10 reaches the raised position. In this way, the cooperation between the first drive assembly 20 and the side brush assembly 10 can be further simplified.

[0164] In some embodiments, the cleaning device 100 may further include a second drive assembly (not shown), which is connected to the connecting shaft 13 and is suitable for driving the connecting shaft 13 to rotate so that the cleaning member 11 performs a cleaning operation. That is, in this embodiment, the first drive assembly 20 is only configured to drive the side brush assembly 10 to reach the cleaning position and the lifting position, and the second drive assembly is configured to drive the side brush assembly 10 to rotate after the first drive assembly 20 drives the side brush assembly 10 to reach the cleaning position to clean the surface to be cleaned. In this way, the control method of the first drive assembly 20 and the second drive assembly can be further simplified.

[0165] In some embodiments, in combination Figure 7 and Figure 8 The cleaning device 100 may further include a swing arm 30, which is rotatably connected to the body 40, and the side brush assembly 10 is arranged on the swing arm 30 to follow the movement of the swing arm 30, and the swing arm 30 moves between the retracted position and the outward swing position relative to the body 40, wherein when the swing arm 30 is in the outward swing position, the range of the side brush assembly 10 beyond the body 40 is greater than the range of the side brush assembly 10 beyond the body 40 when the side brush assembly 10 is in the retracted position. In this way, when the side brush assembly is in the retracted position and the outward swing position, the side brush assembly can have different cleaning ranges, for example, when the side brush assembly is in the retracted position, the cleaning device performs conventional cleaning work, and when the side brush assembly is in the outward swing position, the side brush assembly can be closer to the corner area, thereby having a better cleaning effect on the corner area. For example, the swing arm 30 may be provided with a mounting portion, and the mounting portion may be a cavity structure or other structures, and the first drive assembly 20 may be mounted on the mounting portion to achieve the installation of the side brush assembly to the swing arm 30.

[0166] In this way, the side brush assembly 10 can be controlled to move to the side of the body 40 and a certain distance away from the body 40 by controlling the swing of the swing arm 30. In this way, the cleaning range of the cleaning device 100 can be larger and can adapt to more complex cleaning conditions.

[0167] In some possible embodiments, combined with Figure 1 and Figure 6The swing arm 30 can constitute the housing 21 of the first driving assembly 20, that is, the swing arm 30 and the housing 21 are of the same structure, so that the structure of the cleaning device 100 can be further simplified.

[0168] In some embodiments, when the swing arm 30 is in the retracted position, the first drive group 20 drives the side brush assembly 10 to switch between the cleaning position and the lifting position, and at least a portion of the first drive assembly 20 is disposed on the swing arm 30. In this way, the structure of the swing arm 30 and the coordination method with the machine body 40 are relatively simple and easy to implement, and can prevent the side brush assembly from being lifted in the outward swing position, causing the cleaning strip of the side brush assembly to be easily stuck in the moving channel of the side brush assembly for the outward swing movement, thereby affecting the normal operation of the cleaning device. Of course, as an alternative, when the swing arm 30 is in the outward swing position, the first drive group 20 drives the side brush assembly 10 to switch between the cleaning position and the lifting position, and at least a portion of the first drive assembly 20 is disposed on the swing arm 30.

[0169] In some embodiments, the cleaning device 100 further includes a third drive assembly, which is disposed on the body 40 to drive the swing arm 30 to move between the retracted position and the outward swing position; when the side brush assembly 10 is in the cleaning position, the third drive assembly drives the swing arm 30 to move between the retracted position and the outward swing position. In this way, the side brush assembly 10 can perform cleaning tasks in any position of the retracted position and the outward swing position.

[0170] In some possible embodiments, the third driving assembly may include a swing arm driving motor and a swing arm transmission mechanism 22. The swing arm transmission mechanism 22 may be a gear rack mechanism, a gear set mechanism or other structures. Of course, the utility model is not limited to this. The specific structure of the swing arm transmission mechanism 22 may be reasonably set according to actual needs. In this way, by setting a swing arm driving device, it is convenient to control the rotation state of the swing arm 30, thereby flexibly controlling the position of the side brush assembly relative to the body 40, so that the cleaning device 100 can better perform the cleaning task.

[0171] In some embodiments, the cleaning device 100 may further include a position detection device and a control device. Specifically, the position detection device is disposed on the body 40. For example, the position detection device may be a proximity sensor, a radar sensor, an infrared sensor, etc., and of course, it may also be other detection devices. The position detection device may be used to detect the position of the cleaning device 100 and the surrounding environment. The control device is respectively connected to the position detection device and the swing arm 30 drive device by signal. The control device controls the swing arm 30 drive device to move according to the signal of the position detection device to drive the swing arm 30 to rotate. In this way, the degree of automation of the cleaning device 100 can be further improved, and the cleaning task can be smoothly performed, which can improve the user experience.

[0172] In some embodiments, the cleaning device 100 may include a mopping assembly (not shown), for example, the mopping assembly may include a mop, which may be used to mop the floor, wet mop and scrub the surface to be cleaned. The mopping assembly has a mopping position and a mop lifting position, in which the mopping assembly can mop and clean the surface to be cleaned, and in which the mop lifting position, the mopping assembly is separated from the surface to be cleaned.

[0173] The cleaning device 100 has a cleaning mode. When the cleaning device 100 is in the cleaning mode, the side brush assembly 10 is in the cleaning position, and the mopping assembly is in the mop lifting position.

[0174] The cleaning device 100 also has a mopping mode. When the cleaning device 100 is in the mopping mode, the side brush assembly 10 is in a raised position and the mopping assembly is in a mopping position.

[0175] In addition, the cleaning device 100 may also have a sweeping and mopping mode. When the cleaning device 100 is in the sweeping and mopping mode, the side brush assembly 10 is in the cleaning position, and the mopping assembly is in the mopping position.

[0176] In this way, the cleaning device 100 of this embodiment has more working modes, can adapt to more and more complex working conditions, and improve the user experience.

[0177] When the cleaning device 100 switches from the sweeping and mopping mode to the cleaning mode, the first driving assembly 20 drives the side brush assembly 10 to switch from the cleaning position to the lifting position to prevent the side brush assembly 10 from contacting the surface to be cleaned to cause contamination.

[0178] In some embodiments, the cleaning device 100 may further include a lifting mechanism, which is disposed on the body 40, the mopping assembly is connected to the lifting mechanism, and the lifting mechanism is suitable for driving the mop to move between a mopping position and a mop lifting position.

[0179] In some embodiments, when the side brush assembly 10 performs a cleaning task, the side brush assembly 10 is in a cleaning position; when the side brush assembly 10 performs a cleaning task and a preset condition occurs, the first drive assembly 20 drives the side brush assembly 10 to switch from the cleaning position to the raised position. The preset condition includes at least one of the following: when the cleaning device 100 performs carpet area cleaning; when the cleaning device 100 returns to the base station; when the cleaning device 100 switches to a work task that does not require cleaning; when the cleaning device 100 needs to cross an obstacle; when the cleaning device 100 creates a map; when there are wet stains on the cleaning path of the cleaning device 100. Of course, the utility model is not limited to this. In other cases where the side brush assembly 10 is not required to work, the side brush assembly 10 can be switched from the cleaning position to the raised position under the drive of the first drive assembly 20 to prevent the side brush assembly 10 from contaminating the surface to be cleaned.

[0180] The cleaning device 100 can place the side brush assembly 10 and the second cleaning assembly at different heights and positions in different occasions to adapt to different cleaning scenarios.

[0181] Exemplarily, in a normal cleaning scenario, the side brush assembly 10 and the second cleaning assembly (eg, including a mop) are both in contact with the surface to be cleaned, that is, the side brush assembly 10 is in the cleaning position, and the second cleaning assembly is in the mopping position.

[0182] When the surface to be cleaned has been preliminarily cleaned by the side brush assembly 10 and only needs to be wet mopped and scrubbed, the side brush assembly 10 can be disengaged from the surface to be cleaned and be in a raised position to prevent contamination of the surface to be cleaned, while the second cleaning assembly is in a raised position to perform a special wet mopping operation on the surface to be cleaned.

[0183] When the surface to be cleaned does not need wet mopping but only needs sweeping, the side brush assembly 10 can be placed in the cleaning position and the second cleaning assembly can be placed in the raised position, so that the cleaning device 100 only completes the cleaning operation.

[0184] When the surface to be cleaned has been cleaned, the first cleaning component 10 can be placed in a raised position, and the second cleaning component can also be placed in a raised position, so as to avoid secondary contamination of the cleaning device 100 by the cleaning component when the cleaning device 100 passes over the cleaned surface.

[0185] In this way, the mop can be flexibly controlled to leave the surface to be cleaned as needed to avoid secondary contamination of the surface to be cleaned by the mop or the side brush assembly 10.
