[0049] In the following description, a large number of specific details are given to provide a more thorough understanding of the technical solutions provided by the present utility model. However, it is obvious to those skilled in the art that the technical solutions provided by the present utility model can be implemented without one or more of these details.

[0050] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present utility model. As used herein, unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. In addition, it should also be understood that when the terms "comprising" and / or "including" are used in this specification, they specify the presence of the described features, wholes, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, and / or combinations thereof.

[0051] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present utility model is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill in the art.

[0052] As Figures 1 to 8 shown, according to a first aspect of an embodiment of the present application, a cleaning device is provided, including: a housing 110; a traveling assembly 120, the traveling assembly 120 including a plurality of wheels, the plurality of wheels being connected to the housing 110, and at least some of the plurality of wheels being arranged at the front end of the housing 110; a grasping assembly 130, the grasping assembly 130 being connected to the bottom of the housing 110 and arranged between the plurality of wheels, and when the grasping assembly 130 is in a retracted state, the grasping assembly 130 is within the housing 110.

[0053] The cleaning device provided by the embodiment of the present application includes a housing 110, a traveling assembly 120, and a grasping assembly 130. During the operation of the main body of the cleaning device, the traveling assembly 120 can support the housing 110 of the cleaning device and the components within the housing 110 through the plurality of wheels. By the rotation of the wheels, the housing 110 and the grasping assembly 130 can be driven to move. Through the arrangement of the grasping assembly 130, objects that hinder the operation of the cleaning device can be grasped, which can make the operation process of the cleaning device smoother and improve the cleaning ability.

[0054] In the embodiment of the present application, the cleaning device is connected to the bottom of the housing 110 through the grasping component 130, which can reduce the center of gravity of the grasping component 130. Especially when the grasping component 130 is in the storage state, the center of gravity of the grasping component 130 can be reduced, so that the center of gravity of the grasping component 130 can coincide with the center of gravity of the cleaning device or the two centers of gravity can be relatively close. The center of gravity of the grasping component 130 can be distributed among multiple wheels. Based on this, when the cleaning device climbs over obstacles or slopes, it will be smoother, and the influence of the grasping component 130 on the mobility flexibility of the cleaning device can be reduced or avoided. At the same time, when the grasping component 130 is in the extended or stretched state to work, the center of gravity of the grasping component 130 can also be distributed above the cleaning device, which can prevent the grasping component 130 from tipping over and reduce the probability of the grasping component 130 shaking during work.

[0055] In the cleaning device provided by the embodiment of the present application, at least some of the multiple wheels are arranged at the front end of the housing 110, so that the cleaning device can be better supported. Especially, the grasping component 130 can be better supported by the wheels. It can be understood that the front end of the housing 110 refers to the area at the front of the housing 110 in the traveling direction of the cleaning device. Based on this, when the cleaning device climbs over obstacles or slopes, the wheels can better contact the obstacles or slopes.

[0056] In the cleaning device provided by the embodiment of the present application, the cleaning device is connected to the bottom of the housing 110 through the grasping component 130, which can reduce the center of gravity of the grasping component 130. When the grasping component 130 is in the storage state, it can be completely hidden inside the housing 110, which can reduce the overall height of the cleaning device. Therefore, the cleaning device can have more abundant usage scenarios, further reduce the space size requirements of the cleaning device and the cleaning system, can further improve the user experience, and at the same time make the cleaning device more beautiful.

[0057] In the embodiment of the present application, the cleaning device provided has the grasping assembly 130 arranged between multiple wheel bodies, which can further adjust the center of gravity of the grasping assembly 130 so that the center of gravity of the grasping assembly 130 can be located between the multiple wheel bodies. Based on this, when the grasping assembly 130 is in the working state, such as when the grasping assembly 130 extends and elongates to grasp an object, the center of gravity of the grasping assembly 130 will also be distributed above the cleaning device, which can reduce or prevent the grasping assembly 130 from tipping over, and can avoid the cleaning device from shaking due to unstable center of gravity when the grasping assembly 130 grasps an item, and can ensure the reliability of the cleaning device during operation; when the grasping assembly 130 is in the storage state, it can make the center of gravity of the grasping assembly 130 be distributed in the middle front area of the housing 110, so that the center of gravity can coincide with the center of gravity of the cleaning device or the centers of gravity of the two can be relatively close, so that the center of gravity of the grasping assembly 130 can be distributed between the multiple wheel bodies, and the traveling assembly 120 can better support the cleaning device, further reducing the probability of the grasping assembly 130 tipping over, making the use of the main body of the cleaning device safer and improving the user experience.

[0058] In the cleaning device provided by the embodiment of the present application, through the arrangement method that the grasping assembly 130 is connected to the bottom of the housing 110 and arranged between multiple wheel bodies, the center of gravity of the grasping assembly 130 is regulated in two ways, so that the center of gravity of the grasping assembly 130 is lowered and closer to the overall center of gravity of the cleaning device main body, which can make the cleaning device run more smoothly, prevent the grasping assembly 130 from tipping over, and improve the user experience.

[0059] In the cleaning device provided by the embodiment of the present application, when the grasping assembly 130 is in the storage state, the grasping assembly 130 is inside the housing 110, which can make the cleaning device more beautiful and at the same time can lower the center of gravity, making the cleaning device run more smoothly.

[0060] It can be understood that the grasping assembly 130 may include a robotic arm, and then through the movement of the robotic arm, the grasping or moving of obstacles, objects, and garbage near the cleaning device can be realized to better achieve the autonomous cleaning function. It can be understood that the above objects may also be objects required by users, such as remote controls, fruits, etc., which will not be listed one by one here.

[0061] As Figure 1 shown, in a feasible embodiment, two of the multiple wheel bodies are driving wheels 121, and one of the multiple wheel bodies is an auxiliary wheel 122; wherein, the auxiliary wheel 122 is connected to the housing 110 and arranged at the front end in the traveling direction of the cleaning device, and the two driving wheels 121 are connected to both sides of the housing 110; wherein, the grasping assembly 130 is arranged between the two driving wheels 121 and the auxiliary wheel 122.

[0062] In this technical solution, the styles and layout methods of multiple wheels are further provided. Two of the multiple wheels are driving wheels 121, and one of the multiple wheels is an auxiliary wheel 122. That is to say, during the movement of the cleaning device, it can be driven by the two driving wheels 121. On the one hand, it can ensure sufficient driving force; on the other hand, it is convenient to drive the cleaning device to turn and adjust the traveling direction of the cleaning device. Through the design of the auxiliary wheel 122, the auxiliary wheel 122 can support the housing 110, reduce the gap between the housing 110 and the ground, and further reduce the probability of the cleaning device shaking caused by the change of the center of gravity of the housing 110 due to the grasping assembly 130, which can further improve the user experience.

[0063] It can be understood that the housing 110 can be cylindrical. Taking the moving direction of the cleaning device as the first direction and the direction perpendicular to the first direction as the second direction, the two driving wheels 121 are connected to both sides of the housing 110 means that the two driving wheels 121 are arranged along the second direction on both sides of the housing 110. Of course, the housing 110 can also be polygonal. In this case, the two driving wheels 121 are connected to both sides of the housing 110 means that the two driving wheels 121 are arranged along the length direction of the housing 110 on both sides of the housing 110.

[0064] In this technical solution, the auxiliary wheel 122 is connected to the housing 110 and arranged at the front end in the traveling direction of the cleaning device. The two driving wheels 121 are connected to both sides of the housing 110. That is to say, the auxiliary wheel 122 and the two driving wheels 121 show a triangular layout trend, which can provide good support for the housing 110. At the same time, the auxiliary wheel 122 is arranged at the front end in the traveling direction of the cleaning device. When crossing an obstacle or climbing a slope, the auxiliary wheel 122 can contact the obstacle or ramp first, which can further improve the obstacle-crossing ability of the cleaning device.

[0065] In this technical solution, the grasping component 130 is arranged between the two driving wheels 121 and the auxiliary wheel 122, which can further adjust the center of gravity of the grasping component 130 so that the center of gravity of the grasping component 130 can be between the driving wheel 121 and the auxiliary wheel 122. Based on this, when the grasping component 130 is in the working state, such as when the grasping component 130 extends and elongates to grasp an object, the center of gravity of the grasping component 130 will also be distributed on the housing 110 of the cleaning device, which can reduce or prevent the grasping component 130 from tipping over, and can avoid the cleaning device from shaking due to unstable center of gravity when the grasping component 130 grasps an object, and can ensure the reliability of the cleaning device operation; when the grasping component 130 is in the storage state, it can make the center of gravity of the grasping component 130 be distributed in the middle front area of the housing 110, so that the center of gravity can coincide with the center of gravity of the cleaning device or the center of gravity of the two can be relatively close, so that the center of gravity of the grasping component 130 can be distributed among multiple wheels, further reducing the probability of the grasping component 130 tipping over, making the use of the main body of the cleaning device safer and improving the user experience.

[0066] As Figure 3 As shown in the figure, in a feasible implementation, a bin 111 is formed in the housing 110, and the grasping component 130 can extend out or be stored in the bin 111 through the bin 111; wherein, the connection direction of the two driving wheels 121 is the first direction, and when the grasping component 130 is in the storage state, the length direction of the grasping component 130 is arranged along the first direction.

[0067] In this technical solution, the style of the housing 110 is further provided. A bin 111 is formed in the housing 110, and the grasping component 130 can extend out or be stored in the bin 111 through the bin 111. With this setting, when the grasping component 130 is in the storage state, the grasping component 130 can be retracted within the bin 111, which can better accommodate the grasping component 130.

[0068] In this technical solution, the connection direction of the two driving wheels 121 is the first direction. When the grasping component 130 is in the storage state, the length direction of the grasping component 130 is arranged along the first direction, that is to say, the length direction of the grasping component 130 can be arranged along the connection direction of the two driving wheels 121. Based on this, when the cleaning device is driven by the two driving wheels 121, the driving force received by the cleaning device can be made more balanced, and the movement of the cleaning device can be made more stable. When the grasping component 130 is in the working state, such as when it changes from an extended or contracted state, the center of gravity of the grasping component 130 can be distributed between the two driving wheels 121, which can make the change of the center of gravity of the grasping component 130 during operation more stable and ensure the reliability of the cleaning device work.

[0069] AsFigure 1 and Figure 2 As shown in Figure 2 , in a feasible implementation, the cleaning device further includes: a cleaning member 140 disposed on a side of the grasping assembly 130 away from the auxiliary wheel 122; and a power supply 150 disposed between the auxiliary wheel 122 and the grasping assembly 130.

[0070] In this technical solution, the structural composition of the cleaning device is further provided. The cleaning device may include a cleaning member 140 and a power supply 150. Through the setting of the cleaning member 140, the cleaning member 140 can clean the ground. The cleaning member 140 may include, but is not limited to, a brush body or a mop, and the power supply 150 is used as the power source for the movement and operation of the cleaning device.

[0071] In this technical solution, the cleaning member 140 is disposed on a side of the grasping assembly 130 away from the auxiliary wheel 122, and the power supply 150 is disposed between the auxiliary wheel 122 and the grasping assembly 130. That is to say, the cleaning member 140 and the power supply 150 are respectively disposed on both sides of the grasping assembly 130. Based on this, in the traveling direction of the cleaning device, the center-of-gravity distribution of the grasping assembly 130 can be made more reasonable, and the center-of-gravity distribution of the grasping assembly 130 can be located in the middle front part of the housing 110, so that the center of gravity of the grasping assembly 130 can coincide with the center of gravity of the cleaning device or the centers of gravity of the two can be relatively close. Based on this, when the cleaning device climbs over obstacles or climbs slopes, it will be smoother, and the influence of the grasping assembly 130 on the flexibility of the movement of the cleaning device can be reduced or avoided. At the same time, when the grasping assembly 130 is in an extended or stretched state for work, the center-of-gravity distribution of the grasping assembly 130 can also be located on the housing 110, the tipping of the grasping assembly 130 can be prevented, and the probability of the grasping assembly 130 shaking during work can be reduced.

[0072] As Figures 5 to 7 As shown in Figures 5 to 7 , in a feasible implementation, the cleaning device further includes: a dust collection assembly 160 disposed on a side of the cleaning member 140 away from the grasping assembly 130; and a main board 170 disposed on top of the power supply 150, between the auxiliary wheel 122 and the grasping assembly 130.

[0073] In this technical solution, it is further provided that the cleaning device may further include a dust collection assembly 160 and a main board 170. The dust collection assembly 160 is conducted to the area where the cleaning member 140 is located, and the cleaning member 140 and the dust collection assembly 160 are disposed on the same side of the grasping assembly 130. With such a setting, it is convenient to collect the dust collected by the cleaning member 140 as soon as possible through the dust collection assembly 160, and the cleaning efficiency of the cleaning device can be improved.

[0074] It can be understood that the dust collection assembly 160 is arranged on the side of the cleaning member 140 away from the grasping assembly 130, which means that in the traveling direction of the cleaning device, the dust collection assembly 160 is arranged on the side of the cleaning member 140 away from the grasping assembly 130.

[0075] In this technical solution, the main board 170 and the power supply 150 are distributed on the other side of the grasping assembly 130, which can make the center of gravity of the grasping assembly 130 distributed in the middle front part of the housing 110, and can make the grasping assembly 130 better supported. The main board 170 can have a connection relationship with the grasping assembly 130, the dust collection assembly 160 and the cleaning member 140, and can control the grasping assembly 130, the dust collection assembly 160 and the cleaning member 140 to perform specific operation actions. The main board 170 is arranged on the top of the power supply 150, making full use of the space on one side of the grasping assembly 130, and can make the layout of the cleaning device more compact.

[0076] It can be understood that the main board 170 and the power supply 150 are distributed on the other side of the grasping assembly 130, which means that in the traveling direction of the cleaning device, the main board 170 and the power supply 150 are distributed on the other side of the grasping assembly 130.

[0077] It can be understood that the present application does not limit the specific style of the dust collection assembly 160. The style of the dust collection assembly 160 can be various. For example, the dust collection assembly 160 can include an air duct and a fan. The air duct is led to the cleaning member 140, and the fan provides a negative pressure environment for the air duct, and the negative pressure environment can collect the dust at the cleaning member 140.

[0078] For example Figure 2 As shown, in a feasible implementation manner, the traveling assembly 120 includes: a lifting and adjusting assembly 123. The lifting and adjusting assembly 123 is connected to the auxiliary wheel 122 and is arranged on the side of the power supply 150 away from the grasping assembly 130.

[0079] For example Figure 3 As shown, in a feasible implementation manner, the housing 110 includes: a bottom plate 112; the grasping assembly 130 is connected to the bottom plate 112, so that when the grasping assembly 130 is in the storage state, the distance between the center of gravity of the grasping assembly 130 and the center of gravity of the overall cleaning device is less than or equal to 10 cm.

[0080] In this technical solution, the grasping assembly 130 is connected to the bottom plate 112. On the one hand, the grasping assembly 130 can be connected to the lowest end of the housing 110. Based on this, the center of gravity of the grasping assembly 130 can be lowered, and the distance between the center of gravity of the grasping assembly 130 and the center of gravity of the overall cleaning device can be less than or equal to 10 cm, which can reduce the probability of the cleaning device tipping over.

[0081] In some examples, the housing may further include a side plate 113 and a top plate 114. The side plate 113 is disposed at the edge of the bottom plate 112, and the top plate 114 is connected to the bottom plate 112 so as to enclose a receiving space between the top plate 114 and the bottom plate 112. It can be understood that, in order to improve the mechanical strength, the side plate 113 and the bottom plate 112 may also be of an integral structure.

[0082] In this technical solution, the structural composition of the housing 110 is further provided. The housing 110 includes: a bottom plate 112, a side plate 113, and a top plate 114. The side plate 113 is disposed at the edge of the bottom plate 112, and the top plate 114 is connected to the bottom plate 112 so as to enclose a receiving space between the top plate 114 and the bottom plate 112. Such a setting facilitates the production and processing of the housing 110. The housing 110 as a whole may be cylindrical or approximately cylindrical, which can ensure that there is enough space inside the housing 110 while enabling the cleaning device to travel in a relatively narrow space.

[0083] In this technical solution, the grasping assembly 130 is connected to the bottom plate 112, which can further reduce the height of the center of gravity of the grasping assembly 130. When the grasping assembly 130 is in the retracted state, the distance between the center of gravity of the grasping assembly 130 and the center of gravity of the entire cleaning device is less than or equal to 10 cm, which can make the center of gravity of the grasping assembly 130 basically coincide with the center of gravity of the entire cleaning device when the grasping assembly 130 is in the retracted state. Based on this, when the grasping assembly 130 is in the working state, such as when the grasping assembly 130 extends and elongates to grasp an object, the center of gravity of the grasping assembly 130 will also be distributed on the housing 110 of the cleaning device, which can reduce or prevent the grasping assembly 130 from tipping over, and can avoid the cleaning device from shaking due to unstable center of gravity when the grasping assembly 130 grasps an object, and can ensure the reliability of the cleaning device during operation; when the grasping assembly 130 is in the retracted state, the center of gravity of the grasping assembly 130 can be distributed in the middle front area of the housing 110, so that the center of gravity can coincide with the center of gravity of the cleaning device or the centers of gravity of the two can be relatively close, and the center of gravity of the grasping assembly 130 can be distributed between the multiple wheels of the traveling assembly 120, further reducing the probability of the grasping assembly 130 tipping over, making the use of the main body of the cleaning device safer and improving the user experience.

[0084] As Figure 8 shown, in a feasible implementation manner, the cleaning device further includes: a reinforcing plate 180. The reinforcing plate 180 is connected to the bottom plate 112, and the grasping assembly 130 is connected to the bottom plate 112 through the reinforcing plate 180.

[0085] In this technical solution, considering that the grasping component 130 is directly connected to the bottom plate 112 of the housing 110, it is possible for the bottom plate 112 of the housing 110 to bear a relatively large weight. Based on this, the cleaning device may further include a reinforcing plate 180. Connecting the grasping component 130 to the bottom plate 112 through the reinforcing plate 180 can lower the center of gravity of the grasping component 130 while ensuring the strength of the housing 110, ensuring the service life of the cleaning device, and reducing the failure rate of the cleaning device.

[0086] As Figure 4 shown, in a feasible implementation, the housing 110 is cylindrical. When the grasping component 130 is in the retracted state, the ratio of the length of the grasping component 130 to the diameter of the housing 110 is 0.5 to 0.8.

[0087] In this technical solution, the style of the housing 110 is further provided. The housing 110 being cylindrical can enable the cleaning device to travel in a relatively narrow space while ensuring that there is enough space inside the housing 110.

[0088] In this technical solution, when the grasping component 130 is in the retracted state, the ratio of the length of the grasping component 130 to the diameter of the housing 110 is 0.5 to 0.8. Based on this, it is convenient to adjust the center of gravity of the grasping component 130 and at the same time convenient to adjust the effective length of the grasping component 130. When the grasping component 130 is in the extended state, it can better grasp objects.

[0089] As Figure 4 shown, in a feasible implementation, when the grasping component 130 is in the retracted state, the ratio of the length of the grasping component 130 to the diameter of the housing 110 is 0.5 to 0.7.

[0090] In this technical solution, the housing 110 can also be of any shape, as long as when the grasping component 130 is in the retracted state, the ratio of the length of the grasping component 130 to the diameter of the housing 110 is 0.5 to 0.7, then it is convenient to adjust the center of gravity of the grasping component 130 and at the same time convenient to adjust the effective length of the grasping component 130. When the grasping component 130 is in the extended state, it can better grasp objects.

[0091] As Figures 1 to 8 shown, according to the second aspect of the embodiments of the present application, a cleaning system is proposed, including: a cleaning device according to any of the above technical solutions; a base station for accommodating the cleaning device.

[0092] The cleaning system provided by the embodiments of the present application includes a cleaning device according to any of the above technical solutions, so this cleaning system has all the beneficial effects of the cleaning device of the above technical solutions.

[0093] The cleaning system provided by the embodiments of the present application includes a cleaning device and a base station. In the non-operating state, the base station can accommodate the cleaning device. When cleaning is required, the base station can replenish cleaning liquid and clean water for the cleaning device, and can also clean the cleaning part 140 of the cleaning device, making the use of the cleaning device more convenient. The grasping assembly 130 of the cleaning device is connected to the bottom of the housing 110, which can lower the center of gravity of the grasping assembly 130. Especially when the grasping assembly 130 is in the retracted state, the center of gravity of the grasping assembly 130 can be lowered, so that the center of gravity of the grasping assembly 130 can coincide with the center of gravity of the cleaning device or the centers of gravity of the two can be relatively close. Based on this, when the cleaning device climbs over obstacles or slopes, it will be smoother, and the influence of the grasping assembly 130 on the mobility of the cleaning device can be reduced or avoided. At the same time, when the grasping assembly 130 is in the extended or stretched state for work, the center of gravity of the grasping assembly 130 can also be distributed above the housing 110, which can prevent the grasping assembly 130 from tipping over and reduce the probability of the grasping assembly 130 shaking during work. The cleaning device is connected to the bottom of the housing 110 through the grasping assembly 130, which can lower the center of gravity of the grasping assembly 130, so that when the grasping assembly 130 is in the retracted state, it can be completely hidden inside the housing 110, reducing the overall height of the cleaning device. Therefore, the cleaning device can have a richer range of use scenarios, further reducing the space requirements for the cleaning device and the cleaning system, improving the user experience, and making the cleaning device more beautiful.

[0094] The cleaning device provided by the embodiments of the present application arranges the grasping assembly 130 between multiple wheel bodies, which can further adjust the center of gravity of the grasping assembly 130, so that the center of gravity of the grasping assembly 130 can be located between the multiple wheel bodies. Based on this, when the grasping assembly 130 is in the working state, such as when the grasping assembly 130 extends and stretches to grasp an object, the center of gravity of the grasping assembly 130 will also be distributed above the housing 110 of the cleaning device, which can reduce or prevent the grasping assembly 130 from tipping over, and can avoid the cleaning device from shaking due to unstable center of gravity when the grasping assembly 130 grasps an object, ensuring the reliability of the cleaning device during operation; when the grasping assembly 130 is in the retracted state, the center of gravity of the grasping assembly 130 can be distributed in the middle front area of the housing 110, making the center of gravity coincide with the center of gravity of the cleaning device or the centers of gravity of the two be relatively close, further reducing the probability of the grasping assembly 130 tipping over, making the use of the main body of the cleaning device safer, and improving the user experience.
