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

[0050] It should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the 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] Exemplary embodiments of the present invention will now be described in greater detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of the present invention thorough and complete and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0052] like Figures 1 to 8 As shown, according to the first aspect of an embodiment of the present application, a cleaning device is proposed, including: a shell 110; a traveling component 120, the traveling component 120 includes a plurality of wheels, and the plurality of wheels are connected to the shell 110; a grabbing component 130, the grabbing component 130 is connected to the bottom of the shell 110 and is arranged between the plurality of wheels. When the grabbing component 130 is in a stored state, the grabbing component 130 is in the shell 110.

[0053] The cleaning device provided in the embodiment of the present application includes a shell 110, a traveling component 120 and a grabbing component 130. During the operation of the main body of the cleaning device, the traveling component 120 can support the shell 110 of the cleaning device and the components inside the shell 110 through multiple wheels. By rotating the wheels, the shell 110 and the grabbing component 130 can be driven to move. Through the setting of the grabbing component 130, objects that hinder the operation of the cleaning device can be grabbed, which can make the operation process of the cleaning device smoother and improve the cleaning ability.

[0054] The cleaning device provided in the embodiment of the present application is connected to the bottom of the shell 110 through the grabbing assembly 130, which can lower the center of gravity of the grabbing assembly 130, especially when the grabbing assembly 130 is in the storage state, the center of gravity of the grabbing assembly 130 can be lowered, so that the center of gravity of the grabbing 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, and the center of gravity of the grabbing assembly 130 can be distributed among multiple wheels. Based on this, the cleaning device will be smoother when crossing obstacles or climbing slopes, and the influence of the grabbing assembly 130 on the flexibility of the movement of the cleaning device can be reduced or avoided. At the same time, when the grabbing assembly 130 is in an extended or elongated state for work, the center of gravity of the grabbing assembly 130 can also be distributed above the cleaning device, which can prevent the grabbing assembly 130 from tipping over and reduce the probability of shaking of the grabbing assembly 130 when working.

[0055] The cleaning device provided in the embodiment of the present application is connected to the bottom of the shell 110 through the grabbing assembly 130, which can lower the center of gravity of the grabbing assembly 130 so that the grabbing assembly 130 can be completely hidden inside the shell 110 when in the storage state, thereby reducing the overall height of the cleaning device. Therefore, the cleaning device can have more diverse usage scenarios, further reduce the space requirements of the cleaning device and the cleaning system, further improve the user experience, and make the cleaning device more beautiful.

[0056] The cleaning device provided by the embodiment of the present application is arranged between the multiple wheel bodies through the grabbing assembly 130, and the center of gravity of the grabbing assembly 130 can be further adjusted so that the center of gravity of the grabbing assembly 130 can be between the multiple wheel bodies. Based on this, when the grabbing assembly 130 is in a working state, such as when the grabbing assembly 130 is extended and stretched to grab an object, the center of gravity of the grabbing assembly 130 will also be distributed above the cleaning device, which can reduce or prevent the grabbing assembly 130 from tipping over, and can avoid the grabbing assembly 130 from causing cleaning problems due to unstable center of gravity when grabbing an object. The cleaning equipment shakes, which can ensure the reliability of the cleaning equipment operation; when the grabbing assembly 130 is in the storage state, the center of gravity of the grabbing assembly 130 can be distributed in the middle front area of the shell 110, so that the center of gravity can coincide with the center of gravity of the cleaning equipment or the centers of gravity of the two can be relatively close, so that the center of gravity of the grabbing assembly 130 can be distributed among multiple wheel bodies, the traveling assembly 120 can better support the cleaning equipment, further reducing the probability of the grabbing assembly 130 tipping over, making the use of the cleaning equipment body safer, and improving the user experience.

[0057] The cleaning device provided in the embodiment of the present application is connected to the bottom of the shell 110 through the grabbing assembly 130, and is arranged between multiple wheels. The center of gravity of the grabbing assembly 130 is regulated in two ways, so that the center of gravity of the grabbing assembly 130 is lowered and closer to the center of gravity of the entire cleaning device body. This can make the cleaning device run more smoothly, prevent the grabbing assembly 130 from tipping over, and improve the user experience.

[0058] In the cleaning device provided in the embodiment of the present application, when the grabbing assembly 130 is in the storage state, the grabbing assembly 130 is in the shell 110, which can make the cleaning device more beautiful and at the same time lower the center of gravity, making the cleaning device run more smoothly.

[0059] It is understood that the gripping assembly 130 may include a robotic arm, and the movement of the robotic arm can be used to grasp or move obstacles, objects, or garbage near the cleaning device to better achieve the autonomous cleaning function. It is understood that the above-mentioned objects can also be objects required by the user, such as remote controls, fruits, etc., which are not listed here one by one.

[0060] like Figure 1 As 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 shell 110 and is arranged at the front end of the moving direction of the cleaning equipment, and the two driving wheels 121 are connected to both sides of the shell 110; wherein, the grabbing assembly 130 is arranged between the two driving wheels 121 and the auxiliary wheel 122.

[0061] This technical solution further provides the styles and layout of multiple wheel bodies. Two of the multiple wheel bodies are active wheels 121, and one of the multiple wheel bodies is an auxiliary wheel 122. In other words, during the movement of the cleaning device, it can be driven by the dual active 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 direction of travel of the cleaning device. The design of the auxiliary wheels 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 grab assembly 130, which can further improve the user experience.

[0062] It can be understood that the housing 110 can be cylindrical, with 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, which means that the two driving wheels 121 are arranged on both sides of the housing 110 along the second direction. 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, which means that the two driving wheels 121 are arranged on both sides of the housing 110 along the length direction of the housing 110.

[0063] In this technical solution, the auxiliary wheel 122 is connected to the shell 110 and is arranged at the front end in the direction of travel of the cleaning equipment. The two driving wheels 121 are connected to both sides of the shell 110. That is to say, the auxiliary wheel 122 and the two driving wheels 121 are arranged in a triangular shape, which can provide good support for the shell 110. At the same time, the auxiliary wheel 122 is set at the front end in the direction of travel of the cleaning equipment. When overcoming obstacles or climbing slopes, the auxiliary wheel 122 can preferentially contact obstacles or ramps, which can further improve the obstacle-overcoming ability of the cleaning equipment.

[0064] In this technical solution, the grabbing assembly 130 is arranged between the two driving wheels 121 and the auxiliary wheels 122, and the center of gravity of the grabbing assembly 130 can be further adjusted so that the center of gravity of the grabbing assembly 130 can be between the driving wheels 121 and the auxiliary wheels 122. Based on this, when the grabbing assembly 130 is in a working state, such as when the grabbing assembly 130 is extended and stretched to grab an object, the center of gravity of the grabbing assembly 130 will also be distributed above the housing 110 of the cleaning device, which can reduce or prevent the grabbing assembly 130 from tipping over and avoid the grabbing assembly 130 from tipping over. When grabbing items, the cleaning device shakes due to an unstable center of gravity, thereby ensuring the reliability of the cleaning device operation; when the grabbing assembly 130 is in the storage state, the center of gravity of the grabbing assembly 130 can be distributed in the middle front area of the shell 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 grabbing assembly 130 can be distributed among multiple wheel bodies, further reducing the probability of the grabbing assembly 130 tipping over, making the use of the cleaning device body safer and improving the user experience.

[0065] like Figure 3 As shown, in a feasible embodiment, a bin 111 is formed in the shell 110, and the grasping assembly 130 can be extended through the bin 111 or stored in the bin 111; wherein, the connection direction of the two driving wheels 121 is the first direction, and when the grasping assembly 130 is in the storage state, the length direction of the grasping assembly 130 is arranged along the first direction.

[0066] In this technical solution, a style of a shell 110 is further provided, in which a bin 111 is formed, and the grabbing assembly 130 can be extended through the bin 111 or stored in the bin 111. In this arrangement, when the grabbing assembly 130 is in the stored state, the grabbing assembly 130 can be retracted within the bin 111, which can better accommodate the grabbing assembly 130.

[0067] In this technical solution, the connection direction of the two driving wheels 121 is the first direction. When the grabbing assembly 130 is in the storage state, the length direction of the grabbing assembly 130 is arranged along the first direction, that is, the length direction of the grabbing assembly 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 more balanced, and the movement of the cleaning device can be made more stable. When the grabbing assembly 130 is in the working state, such as when it is in the transition from an extension or contraction state, the center of gravity of the grabbing assembly 130 can be distributed between the two driving wheels 121, which can make the change of the center of gravity of the grabbing assembly 130 during the operation more stable and ensure the reliability of the operation of the cleaning device.

[0068] like Figure 1 and Figure 2 As shown, in a feasible embodiment, the cleaning device further includes: a cleaning member 140 , which is arranged on a side of the gripping assembly 130 away from the auxiliary wheel 122 ; and a power supply 150 , which is arranged between the auxiliary wheel 122 and the gripping assembly 130 .

[0069] In this technical solution, the structural composition of the cleaning equipment is further provided. The cleaning equipment may include a cleaning component 140 and a power supply 150. Through the setting of the cleaning component 140, the cleaning component 140 can clean the floor. The cleaning component 140 may include but is not limited to a brush body or a mop, and the power supply 150 serves as a power source for the movement and operation of the cleaning equipment.

[0070] In this technical solution, the cleaning member 140 is arranged on the side of the grabbing assembly 130 away from the auxiliary wheel 122, and the power supply 150 is arranged between the auxiliary wheel 122 and the grabbing assembly 130, that is, the cleaning member 140 and the power supply 150 are respectively arranged on both sides of the grabbing assembly 130. Based on this, in the direction of travel of the cleaning device, the center of gravity of the grabbing assembly 130 can be distributed more reasonably, and the center of gravity of the grabbing assembly 130 can be distributed in the middle and front part of the shell 110, so that the center of gravity of the grabbing assembly 130 is It can coincide with the center of gravity of the cleaning equipment or the centers of gravity of the two can be relatively close, based on this, the cleaning equipment will be smoother when crossing obstacles or climbing slopes, and can reduce or avoid the impact of the grabbing component 130 on the flexibility of the movement of the cleaning equipment. At the same time, when the grabbing component 130 is in an extended or elongated state for work, the center of gravity of the grabbing component 130 can also be distributed above the shell 110, which can prevent the grabbing component 130 from tipping over and reduce the probability of shaking when the grabbing component 130 is working.

[0071] like Figures 5 to 7 As shown, in a feasible embodiment, the cleaning device also includes: a dust collection component 160, which is arranged on the side of the cleaning member 140 away from the grabbing component 130; and a main board 170, which is arranged on the top of the power supply 150 and is located between the auxiliary wheel 122 and the grabbing component 130.

[0072] In this technical solution, it is further provided that the cleaning device may also include a dust collecting component 160 and a main board 170. The dust collecting component 160 is connected to the area where the cleaning member 140 is located, and the cleaning member 140 and the dust collecting component 160 are arranged on the same side of the grabbing component 130. Such an arrangement facilitates the dust collection of the cleaning member 140 by the dust collecting component 160 as soon as possible, thereby improving the cleaning efficiency of the cleaning device.

[0073] It can be understood that the dust collecting assembly 160 is arranged on the side of the cleaning member 140 away from the gripping assembly 130, which means that the dust collecting assembly 160 is arranged on the side of the cleaning member 140 away from the gripping assembly 130 in the traveling direction of the cleaning device.

[0074] In this technical solution, the motherboard 170 and power supply 150 are located on the other side of the gripping assembly 130, which can distribute the center of gravity of the gripping assembly 130 in the middle and front part of the housing 110, thus better supporting the gripping assembly 130. The motherboard 170 can be connected to the gripping assembly 130, the dust collection assembly 160, and the cleaning element 140, and can control the gripping assembly 130, the dust collection assembly 160, and the cleaning element 140 to perform specific operations. The motherboard 170 is placed on top of the power supply 150, making full use of the space on the side of the gripping assembly 130 and making the layout of the cleaning equipment more compact.

[0075] It is understandable that the mainboard 170 and the power supply 150 are distributed on the other side of the grabbing assembly 130 , which means that the mainboard 170 and the power supply 150 are distributed on the other side of the grabbing assembly 130 in the moving direction of the cleaning device.

[0076] It is understandable that the present application does not limit the specific style of the dust collecting component 160. The style of the dust collecting component 160 can be various. For example, the dust collecting component 160 can include an air duct and a fan. The air duct is connected to the cleaning part 140, and the fan provides a negative pressure environment for the air duct. The negative pressure environment can collect dust at the cleaning part 140.

[0077] like Figure 2 As shown, in a feasible embodiment, the traveling component 120 includes: a lifting and adjusting component 123 , which is connected to the auxiliary wheel 122 and is arranged on a side of the power supply 150 away from the grabbing component 130 .

[0078] like Figure 3 As shown, in a feasible embodiment, the shell 110 includes: a base plate 112; a grabbing assembly 130 connected to the base plate 112, so that when the grabbing assembly 130 is in a storage state, the distance between the center of gravity of the grabbing assembly 130 and the center of gravity of the cleaning device as a whole is less than or equal to 10 cm.

[0079] In this technical solution, the grabbing assembly 130 is connected to the base plate 112. On the one hand, the grabbing assembly 130 can be connected to the lowest end of the shell 110. Based on this, the center of gravity of the grabbing assembly 130 can be lowered, and the distance between the center of gravity of the grabbing assembly 130 and the center of gravity of the entire cleaning equipment can be less than or equal to 10 cm, which can reduce the probability of the cleaning equipment tipping over.

[0080] In some examples, the housing may further include side panels 113 and a top panel 114. The side panels 113 are disposed at the edges of the bottom panel 112, and the top panel 114 is connected to the bottom panel 112, so that a receiving space is enclosed between the top panel 114 and the bottom panel 112. It is understood that in order to improve mechanical strength, the side panels 113 and the bottom panel 112 may also be an integrated structure.

[0081] In this technical solution, the structural composition of the shell 110 is further provided. The shell 110 includes: a bottom plate 112, a side plate 113 and a top plate 114. The side plate 113 is arranged at the edge of the bottom plate 112, and the top plate 114 is connected to the bottom plate 112, so that a storage space is enclosed between the top plate 114 and the bottom plate 112. Such an arrangement facilitates the production and processing of the shell 110. The shell 110 as a whole can be cylindrical or approximately cylindrical, which ensures that there is a sufficiently large space inside the shell 110 while enabling the cleaning equipment to travel in a relatively narrow space.

[0082] In this technical solution, the grabbing assembly 130 is connected to the bottom plate 112, which can further reduce the height of the center of gravity of the grabbing assembly 130. When the grabbing assembly 130 is in the storage state, the distance between the center of gravity of the grabbing assembly 130 and the center of gravity of the cleaning device as a whole is less than or equal to 10 cm, which can make the center of gravity of the grabbing assembly 130 basically coincide with the center of gravity of the cleaning device as a whole when the grabbing assembly 130 is in the storage state. Based on this, when the grabbing assembly 130 is in the working state, such as when the grabbing assembly 130 is extended and stretched to grab an object, the center of gravity of the grabbing assembly 130 will also be distributed above the housing 110 of the cleaning device, which can reduce or eliminate the grabbing assembly 130 does not tip over, which can prevent the cleaning device from shaking due to the unstable center of gravity of the grabbing component 130 when grabbing items, and can ensure the reliability of the cleaning device operation; when the grabbing component 130 is in the storage state, the center of gravity of the grabbing component 130 can be distributed in the middle front area of the shell 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 grabbing component 130 can be distributed between the multiple wheels of the traveling component 120, which further reduces the probability of the grabbing component 130 tipping over, makes the use of the cleaning device main body safer, and can improve the user experience.

[0083] like Figure 8 As shown, in a feasible embodiment, the cleaning device further includes: a reinforcing plate 180 , the reinforcing plate 180 is connected to the bottom plate 112 , and the grabbing assembly 130 is connected to the bottom plate 112 via the reinforcing plate 180 .

[0084] In this technical solution, considering that the grabbing assembly 130 is directly connected to the bottom plate 112 of the shell 110, the bottom plate 112 of the shell 110 may bear a large weight. Based on this, the cleaning equipment can also include a reinforcement plate 180. The grabbing assembly 130 is connected to the bottom plate 112 through the reinforcement plate 180. While lowering the center of gravity of the grabbing assembly 130, it can ensure the strength of the shell 110, ensure the service life of the cleaning equipment, and reduce the failure rate of the cleaning equipment.

[0085] like Figure 4 As shown, in a feasible embodiment, the housing 110 is cylindrical, and when the grabbing assembly 130 is in the storage state, the ratio of the length of the grabbing assembly 130 to the diameter of the housing 110 is 0.5 to 0.8.

[0086] In this technical solution, a style of the shell 110 is further provided. The shell 110 is cylindrical, which ensures that there is a sufficiently large space inside the shell 110 while enabling the cleaning device to move in a relatively narrow space.

[0087] In this technical solution, when the grasping component 130 is in the storage state, the ratio of the length of the grasping component 130 to the diameter of the shell 110 is 0.5 to 0.8. Based on this, it is convenient to regulate the center of gravity of the grasping component 130, and at the same time it is 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.

[0088] like Figure 4 As shown, in a feasible embodiment, when the gripping assembly 130 is in the stored state, the ratio of the length of the gripping assembly 130 to the diameter of the housing 110 is 0.5 to 0.7.

[0089] In this technical solution, the shell 110 can also be of any shape. It only needs to be that when the grasping component 130 is in the storage state, the ratio of the length of the grasping component 130 to the diameter of the shell 110 is 0.5 to 0.7. This will facilitate the regulation of the center of gravity of the grasping component 130 and the adjustment of the effective length of the grasping component 130. When the grasping component 130 is in the extended state, it can better grasp objects.

[0090] like Figures 1 to 8 As shown, according to the second aspect of an embodiment of the present application, a cleaning system is proposed, comprising: a cleaning device as described in any of the above technical solutions; and a base station, the base station being used to accommodate the cleaning device.

[0091] The cleaning system provided in the embodiment of the present application includes the cleaning equipment of any of the above technical solutions, so the cleaning system has all the beneficial effects of the cleaning equipment of the above technical solutions.

[0092] The cleaning system provided in the embodiment of the present application includes a cleaning device and a base station. In a non-operating state, the base station can accommodate the cleaning device. When operation is required, the base station can replenish cleaning fluid and clean water for the cleaning device, and can also clean the cleaning parts 140 of the cleaning device, making the use of the cleaning device more convenient. The grabbing assembly 130 of the cleaning equipment is connected to the bottom of the shell 110, which can lower the center of gravity of the grabbing assembly 130, especially when the grabbing assembly 130 is in the storage state, the center of gravity of the grabbing assembly 130 can be lowered, so that the center of gravity of the grabbing assembly 130 can coincide with the center of gravity of the cleaning equipment or the centers of gravity of the two can be relatively close. Based on this, the cleaning equipment will be smoother when crossing obstacles or climbing slopes, and the impact of the grabbing assembly 130 on the flexibility of the movement of the cleaning equipment can be reduced or avoided. At the same time, when the grabbing assembly 130 is in an extended or elongated state for work, the center of gravity of the grabbing assembly 130 can also be distributed above the shell 110, which can prevent the grabbing assembly 130 from tipping over and reduce the probability of shaking of the grabbing assembly 130 when working. The cleaning device is connected to the bottom of the shell 110 through the grabbing assembly 130, which can lower the center of gravity of the grabbing assembly 130 so that the grabbing assembly 130 can be completely hidden inside the shell 110 when in the storage state, thereby reducing the overall height of the cleaning device. Therefore, the cleaning device can have more diverse usage scenarios, further reducing the space requirements of the cleaning device and the cleaning system, further improving the user experience, and making the cleaning device more beautiful.

[0093] The cleaning device provided in the embodiment of the present application is arranged between the multiple wheel bodies through the grabbing assembly 130, and the center of gravity of the grabbing assembly 130 can be further adjusted so that the center of gravity of the grabbing assembly 130 can be located between the multiple wheel bodies. Based on this, when the grabbing assembly 130 is in a working state, such as when the grabbing assembly 130 is extended and stretched to grab an object, the center of gravity of the grabbing assembly 130 will also be distributed on the shell 110 of the cleaning device, which can reduce or prevent the grabbing assembly 130 from tipping over, and can avoid the grabbing assembly 130 from shaking the cleaning device due to unstable center of gravity when grabbing objects, thereby ensuring the reliability of the operation of the cleaning device; when the grabbing assembly 130 is in a stored state, the center of gravity of the grabbing assembly 130 can be distributed in the middle and front area of the shell 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, further reducing the probability of the grabbing assembly 130 tipping over, making the use of the cleaning device body safer, and improving the user experience.
