[0029] See also Figures 1 to 5 , Figure 1 It is a schematic diagram of the overall structure of an embodiment of a cleaning robot of the present application; Figure 2 is a schematic diagram of a cleaning mechanism in a descending state in an embodiment of the cleaning robot of the present application; Figure 3 is a schematic diagram of a cleaning mechanism in an embodiment of the cleaning robot of the present application in a raised state; Figure 4 It is a partial structural schematic diagram of an embodiment of a cleaning robot of the present application; Figure 5 It is a schematic diagram of a partial explosion structure of an embodiment of the cleaning robot of the present application.

[0030] An embodiment of the present application provides a cleaning robot 10. The cleaning robot 10 includes a frame 11, a cleaning mechanism 12, and a shielding device 14. The cleaning mechanism 12 and the shielding device 14 are both arranged on the frame 11, so the frame 11 can play a certain supporting role for the cleaning mechanism 12 and the shielding device 14 to ensure the stability of the installation of the cleaning mechanism 12 and the shielding device 14.

[0031] Furthermore, the shielding device 14 includes a driving component 141 and a shielding component 142. The driving component 141 can drive the shielding component 142 to unfold to cover the bottom of the cleaning mechanism 12. At this time, by covering the bottom of the cleaning mechanism 12 with the shielding component 142, it is possible to prevent the sewage or stains on the cleaning mechanism 12 from contaminating the area to be cleaned; the driving component 141 can also drive the shielding component 142 to reel in to expose the cleaning mechanism 12, and the cleaning mechanism 12 can clean the area that needs to be cleaned. Therefore, the setting of the driving component 141 driving the shielding component 142 to reel in or unfold can not only maintain the cleaning function of the cleaning mechanism 12, but also cover the cleaning mechanism 12 when it is necessary to shield the cleaning mechanism 12, so as to isolate the cleaning mechanism 12 and the cleaning area, avoid contaminating the cleaning area, and thus improve the cleaning effect. Among them, the cleaning mechanism 12 can at least be a roller brush module 122, a mop module 121, etc. Specifically, when the cleaning mechanism 12 includes a mop module 121 and a roller brush module 122, the driving component 141 can drive the shielding component 142 to expand to cover the mop module. At this time, when the cleaning robot 10 is cleaning some specific ground areas, the roller brush module 122 can work normally, and the sewage on the mop module 121 will not drip onto the specific ground area, wherein the specific ground area can be carpets, blankets and other items. At this time, the cleaning mechanism 10 will not cause secondary pollution to specific ground areas such as carpets and blankets. The driving component 141 can also drive the shielding component 142 to reel in to expose the cleaning mechanism 12. At this time, when the cleaning robot 10 moves from a specific ground area to other locations on the ground, the various cleaning modules of the cleaning mechanism 12 can normally clean and wipe the ground.

[0032] Therefore, the driving component 141 drives the shielding component 142 to unfold or retract, which can not only prevent the cleaning robot 10 from secondary contamination of the specific ground area during the process of cleaning the specific ground area, but also can clean the remaining ground again after leaving the specific ground area. Therefore, it can not only ensure the cleaning effect and improve the user experience, but also ensure the cleaning efficiency.

[0033] In one embodiment of the present application, the shielding assembly 142 includes a winding member 1421 and a shielding member 1422. The winding member 1421 is located at one side of the cleaning mechanism 12 and is rotatably disposed on the frame 11. One end of the shielding member 1422 is fixed to the winding member 1421, and the shielding member 1422 is wound around the winding member 1421. The driving assembly 141 can drive the shielding member 1422 to extend to the other side of the cleaning mechanism 12 to cover the bottom of the cleaning mechanism 12, and the driving assembly 141 can drive the shielding member 1422 to be retracted and wound around the winding member 1421. Specifically, during the unfolding process of the shielding member 1422, the driving assembly 141 drives the winding member 1421. Since the shielding member 1422 is wound around the winding member 1421, the movement of the winding member 1421 can drive the shielding member 1422 to extend toward the other side of the cleaning mechanism 12 until it covers the bottom of the cleaning mechanism 12. During the process of the shielding member 1422 being rolled up, the driving assembly 141 drives the winding member 1421 to rotate. At this time, the rotation direction of the winding member 1421 is opposite to the rotation direction of the winding member 1421 when the shielding member 1422 is unfolded, so that the shielding member 1422 can be retracted and wound on the winding member 1421 through the movement of the winding member 1421. In this embodiment, the unfolding and winding of the shielding member 1422 can be achieved by driving the winding member 1421 to rotate by the driving assembly 141, which can make the entire winding and unfolding process more labor-saving and quick. When the cleaning robot 10 passes through a carpet, a blanket, etc., the shielding member 1422 can be unfolded in a short time, thereby being able to avoid the sewage on the cleaning mechanism 12 from dripping onto the carpet, a blanket, etc. to cause secondary pollution, and at the same time, it can quickly resume the cleaning of the ground when leaving the carpet, a blanket, etc. Therefore, the entire structure can achieve a better cleaning effect, thereby improving the user's sense of use.

[0034] Specifically, the driving assembly 141 includes an active roller 1411, a transmission roller 1412 and a first power member 1413. The active roller 1411 is rotatably disposed on the frame 11. The transmission roller 1412 is rotatably disposed on the frame 11 and abuts against the active roller 1411, and the shielding member 1422 is assumed to be between the active roller 1411 and the transmission roller 1412. The first power member 1413 can drive the active roller 1411 and the winding member 1421 to rotate forwardly, so that the shielding member 1422 transfers the bottom of the cleaning mechanism 12 to cover the bottom of the cleaning mechanism 12. The first power member 1413 can also drive the active roller 1411 and the winding member 1421 to rotate in the opposite direction, so that the shielding member 1422 is rolled up and recovered to the winding member 1421. During the unfolding of the shielding member 1422, the first power member 1413 drives the active roller 1411 and the winding member 1421 to rotate in the forward direction. At this time, since the driving roller 1412 is against the active roller 1411, the rotation of the active roller 1411 can drive the driving roller 1412 to rotate, and the shielding member 1422 is sandwiched between the active roller 1411 and the driving roller 1412, so that the shielding member 1422 can be driven toward the bottom of the cleaning mechanism 12 to cover the bottom of the cleaning mechanism 12 through the rotation of the active roller 1411 and the driving roller 1412. When the shielding member 1422 is in the process of winding, the first power member 1413 drives the active roller 1411 and the winding member 1421 to rotate in the reverse direction. At this time, the active roller 1411 drives the driving roller 1412 to rotate in the reverse direction, so that the shielding member 1422 can be wound back to the winding member 1421. By driving the active roller 1411 and the winding member 1421 through the first driving member, the entire driving process can be made more labor-saving, and the transmission roller 1412 and the active roller 1411 are offset against each other. At this time, there is no need to set up additional driving mechanisms to drive the transmission roller 1412 to rotate, thereby better saving the number of structural parts to further save costs, and at the same time, it can also better improve the overall compactness and reliability of the structure.

[0035] Further, in one embodiment of the present application, the first power member 1413 includes a first transmission wheel 1415, a second transmission wheel 1416, a driving wheel 1417, a conveyor belt 1414 and a first motor 1418. The first transmission wheel 1415 is arranged at the end of the driving roller 1411, and the second transmission wheel 1416 is arranged at the end of the winding member 1421. The driving wheel 1417 is rotatably arranged on the frame 11. The conveyor belt 1414 is wound around the outer periphery of the first transmission wheel 1415, the second transmission wheel 1416 and the driving wheel 1417. The first motor 1418 drives the driving wheel 1417 to rotate. Specifically, during the unfolding of the shielding member 1422, the first motor 1418 drives the active wheel 1417 to rotate forwardly. At this time, the positive rotation of the active wheel 1417 can drive the conveyor belt 1414 to rotate, and when the conveyor belt 1414 rotates, it drives the first transmission wheel 1415 and the second transmission wheel 1416 to rotate forwardly. Since the first transmission wheel 1415 is arranged at the end of the active roller 1411, the first transmission wheel 1415 can drive the active roller 1411 to rotate forwardly after the positive rotation, and then the active roller 1411 can drive the transmission roller 1412 to rotate forwardly, and the shielding member 1422 is arranged between the active roller 1411 and the transmission roller 1412, so that the positive rotation of the active roller 1411 and the transmission roller 1412 can drive the shielding member 1422 toward the bottom of the cleaning mechanism 12 to cover the bottom of the cleaning mechanism 12. During the process of winding up the shielding member 1422, the first motor 1418 drives the driving wheel 1417 to rotate in the opposite direction. At this time, the reverse rotation of the driving wheel 1417 drives the conveyor belt 1414 to rotate in the opposite direction, and the reverse rotation of the conveyor belt 1414 drives the first transmission wheel 1415 and the second transmission wheel 1416 to rotate in the opposite direction. Since the first transmission wheel 1415 is arranged at the end of the active roller 1411, the reverse rotation of the first transmission wheel 1415 can drive the active roller 1411 to rotate in the opposite direction, and then the active roller 1411 rotates in the opposite direction to drive the transmission roller 1412 to rotate in the opposite direction. Since the shielding member 1422 is arranged between the active roller 1411 and the transmission roller 1412, the shielding member 1422 can be driven by the active roller 1411 and the transmission roller 1412 to rotate in the opposite direction to drive the shielding member 1422 to be wound onto the winding member 1421. By setting up a first power member 1413 to drive the driving wheel 1417, and transmitting the power of the driving wheel 1417 to the first transmission wheel 1415 and the second transmission wheel 1416 through the transmission belt 1414, this method has the characteristic of more labor-saving driving, and at the same time, it can also enable the driving roller 1411 and the winding member 1421 to rotate synchronously in the process of driving the shielding member 1422 to reel or driving the shielding member 1422 to unfold, so as to avoid rotation errors between the two and damage to the structure of the shielding member 1422 itself, thereby improving the reliability of the structure.

[0036] Preferably, the shielding member 1422 is made of PVC. Of course, in some other embodiments, the shielding member 1422 may also be made of cotton cloth. In this case, a support member may be provided at the bottom of the shielding member 1422 so that the shielding member 1422 does not sag under its own gravity. Alternatively, the shielding member 1422 may also be made of other materials, which is not limited here.

[0037] Please continue reading Figures 1 to 6 , Figure 6 It is a structural schematic diagram of the cleaning robot of one embodiment of the present application, in which the shielding member cooperates with the accommodating guide rail when unfolded.

[0038] In one embodiment of the present application. The cleaning robot 10 also includes a lifting assembly 16. The lifting assembly 16 is disposed on the frame 11. The lifting assembly 16 can drive the cleaning mechanism 12 to lift or lower. Specifically, when the cleaning robot 10 moves to the ground of a specific area, that is, moves to a location such as a carpet or a blanket, at this time, the lifting assembly 16 can drive the cleaning mechanism 12 to lift. At this time, the cleaning mechanism 12 will not contact the location such as the carpet or the blanket, thereby preventing the sewage on the cleaning mechanism 12 from adhering to items such as the carpet or the blanket, affecting the cleaning effect.

[0039] Furthermore, the cleaning mechanism 12 includes a cleaning base 161 and a cleaning member 162. The cleaning member 162 is disposed on the cleaning base 161, and a receiving track 163 is formed on both sides of the cleaning base 161. When the lifting assembly 16 drives the cleaning mechanism to lift, the shielding member 1422 sandwiched between the active roller 1411 and the transmission roller 1412 is directly opposite to the receiving track 163. Specifically, when the cleaning robot 10 moves to the ground of a specific area, that is, moves to a position such as a carpet or a blanket, at this time, the lifting assembly 16 drives the cleaning mechanism 12 to lift, at this time, the cleaning mechanism 12 will not contact the position such as the carpet or the blanket, and at this time, the shielding member 1422 is unfolded, and when the shielding member 1422 is unfolded, the shielding member 1422 is located in the accommodating track 163, at this time, the accommodating track 163 can limit the shielding member 1422 and play a certain supporting role for the shielding member 1422, at this time, the shielding member 1422 can just cover the cleaning mechanism 12, on the one hand, it can prevent the sewage on the cleaning mechanism 12 from dripping onto the carpet, blanket and other items to cause secondary pollution, on the other hand, it can also prevent the shielding member 1422 from being too large and causing waste of materials. In addition, it can also prevent the shielding member 1422 from sagging and rubbing against the ground under its own action. Therefore, the arrangement of the accommodating rail 163 can not only support the shielding member 1422 , but also save the material of the shielding member 1422 and improve the cleaning effect of the cleaning robot 10 .

[0040] See also Figure 1 , Figures 7 and 8 , Figure 7is a schematic diagram of a shielding member of another embodiment of the cleaning robot of the present application in a retracted state; Figure 8 This is a schematic diagram of a shielding member of another embodiment of the cleaning robot of the present application in an unfolded state.

[0041] In another embodiment of the present application, the cleaning mechanism 12 has a first side A and a second side B that are relatively arranged. The winding member 1421 is located on one side of the cleaning mechanism 12. The driving mechanism includes a traction guide rail 151, a traction beam 152, a shielding member 1422 and a second power member 153. Among them, the traction guide rail 151 extends from the first side A to the second side B and is located at the periphery of the cleaning mechanism 12. The traction beam 152 can reciprocate along the traction guide rail 151. The free end of the shielding member 1422 is fixed to the traction beam 152. The second power member 153 can drive the traction beam 152 to move from the first side A to the second side B, and the shielding member 1422 has been pulled to cover the bottom of the cleaning mechanism 12. The second power member 153 can drive the traction beam 152 to move from the second side B to the first side A, so as to drive the shielding member 1422 to move toward the winding member 1421. Specifically, when the shielding member 1422 is in the unfolded state, the traction beam 152 extends from the first side A to the second side B on the traction guide rail 151, so that the traction beam 152 can drive the shielding member 1422 to move to cover the cleaning mechanism 12. At this time, the cleaning mechanism 12 is covered. When the cleaning robot 10 moves to a position such as a blanket or carpet, the sewage on the cleaning mechanism 12 will not drip onto the blanket or carpet, thereby preventing the blanket or carpet from receiving secondary pollution, thereby improving the user's experience. When the shielding member 1422 is in the reeled state, the traction beam 152 extends from the second side B to the first side A on the traction guide rail 151, and then the traction beam 152 can drive the shielding member 1422 to move to be completely retracted by moving. At this time, when the cleaning robot 10 moves to a position on the ground other than the blanket or carpet, the cleaning mechanism 12 can be exposed so that the cleaning mechanism 12 can clean the ground again. Therefore, the setting of the above-mentioned mechanism can not only enable the cleaning robot 10 to avoid secondary pollution to carpets, blankets, etc. when moving to carpets, blankets, etc., but also can quickly resume cleaning of the ground when leaving carpets, blankets, etc., so it can well improve the cleaning effect of the entire cleaning robot 10 and improve the user experience.

[0042] Furthermore, the driving assembly 141 further includes a force-returning member 154, wherein the force-returning member 154 is disposed at the end of the winding member 1421, and the force-returning member 154 accumulates force when the shielding member 1422 extends outward, so that the winding member 1421 has a tendency to rotate in the direction of winding the shielding member 1422. Preferably, the force-returning member 154 is a torsion spring. Specifically, when the shielding member 1422 is being deployed, the shielding member 1422 has a relatively large force for extending outward. Although the torsion spring will accumulate force during the process of the shielding member 1422 extending outward, the force for the shielding member 1422 to extend outward is always greater than the elastic force of the torsion spring during the process. As the elastic force of the torsion spring gradually increases, the torsion spring can also make the winding member 1421 have a tendency to rotate in the direction of winding the shielding member 1422. When the shielding member 1422 needs to be wound up, the force for the shielding member 1422 to extend outward disappears, and the torsion spring will drive the shielding member 1422 to be wound up onto the winding member 1421 under the action of its own elastic force. When the shielding member 1422 is completely wound up onto the winding member 1421, the elastic force of the torsion spring is reduced to 0, and the shielding member 1422 can remain relatively stationary with the winding member 1421 on the winding member 1421. Therefore, by providing a torsion spring, the shielding member 1422 can be reeled in without an additional driving member. Compared with the driving member, the structure of the torsion spring is simpler, the cost is lower, and the structural reliability is better.

[0043] Of course, in some other embodiments, the rebound member 154 may also adopt other structures, which will not be described here one by one.

[0044] In another embodiment of the present application. The second power member 153 includes a rack 1531, a sliding housing 1533, a gear 1532 and a first motor 1418. Among them, the rack 1531 is arranged on the traction guide rail 151 along the extension direction of the traction guide rail 151. The sliding housing 1533 is fixed to the end of the traction beam 152 and is slidably arranged on the traction guide rail 151. The gear 1532 is rotatably arranged on the sliding housing 1533, and the gear 1532 is meshed with the rack 1531. The first motor 1418 drives the gear 1532 to rotate. Specifically, during the unfolding process of the shielding member 1422, at this time, the first motor 1418 drives the gear 1532 to move from the first side A toward the second side B, and during the movement of the gear 1532, the gear 1532 is always meshed with the rack 1531. During the process of rewinding the shielding member 1422, the first motor 1418 drives the gear 1532 to move from the second side B of the traction guide rail 151 toward the first side A, and the gear 1532 is always meshed with the rack 1531. During the process of the gear 1532 reciprocating in the traction guide rail 151, the sliding housing 1533 can play a certain role in limiting and supporting the gear 1532. By driving the gear 1532 to rotate by the first motor 1418, and the gear 1532 is meshed with the rack 1531, not only can it save more effort in the process of realizing the reciprocating movement of the traction beam 152, but also the overall structure is simpler and the structural reliability is better.

[0045] Please continue reading Figure 1 ,as well as Figures 7 and 8, in another embodiment of the present application. Two traction guide rails 151 are provided, and are relatively arranged on both sides of the cleaning mechanism 12. The distance between the two traction guide rails 151 gradually decreases from the first side A to the second side B. The cleaning robot 10 also includes a baffle 17, which is located on the second side. The baffle 17 is arranged to fit the edge of the frame 11, and when the traction beam 152 moves to the end of the traction guide rail 151 close to the second side B, the traction beam 152 bends to fit with the baffle 17. Specifically, when the traction beam 152 moves to the end of the traction guide rail 151 close to the second side B, at this time, the traction beam 152 can fit with the outer surface of the frame 11, so that the overall aesthetics of the cleaning robot 10 can be ensured when the shielding member 1422 is in the expanded state. The distance between the traction rails 151 gradually decreases from the first side A to the second side B. At this time, not only can the coverage area of ​​the shielding member 1422 be increased, but also the traction beam 152 can be ensured to always bend toward the end close to the baffle 17 during the unfolding process of the traction beam 152, so that the overall aesthetics of the cleaning robot 10 can be ensured when the shielding member 1422 is in the unfolded state. In addition, the traction rails 151 can also limit the moving distance of the shielding member 1422 together with the baffle 17. When the traction beam 152 moves to the end of the eight-shaped guide rail and contacts the baffle 17, the traction beam 152 stops moving. Therefore, the cooperation between the eight-shaped guide rail and the baffle 17 can not only enable the traction beam 152 to always bend toward the side close to the baffle 17 during the movement, but also play a certain role in limiting the moving position of the traction beam 152.

[0046] Of course, in order to ensure that the traction beam 152 is always bent toward the side close to the baffle 17 when the traction beam 152 moves from the first side A to the second side B on the traction guide rail 151, when the traction beam 152 is on the first side A of the traction guide rail 151, the traction beam 152 is also slightly bent toward the side close to the baffle 17. At this time, the reliability of the structure during movement can be guaranteed.

[0047] Furthermore, in the present application, the cleaning robot 10 may be circular, in which case the baffle 17 is bent to maintain the same arc as the frame 11 of the cleaning robot 10, and similarly, the traction beam 152 maintains the same arc as the frame 11 after being unfolded. In some other embodiments, the cleaning robot 10 may also be square, or a combination of square and circle, in which case the baffle 17 and the traction beam 152 are adjusted to adapt to the frame shape of the cleaning robot 10, and no further restrictions are imposed on the appearance of the cleaning robot 10.

[0048] It should be noted that, in another embodiment of the present application, the structure of the lifting assembly 16 and the material of the shielding member 1422 are substantially the same as those of the previous embodiment, and will not be described in detail here.

[0049] It should be noted that the terms "horizontal", "vertical" and the like do not mean that the components are absolutely horizontal or vertical, but can be slightly tilted; the terms "parallel", "vertical" and the like do not mean that the components are absolutely parallel or vertical, but can form a certain angle deviation. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted. In addition, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the product of the present application is usually placed when used, which is only for the convenience of describing the embodiments of the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.

[0050] It is to be understood that the meaning of "plurality" herein is at least two, such as two, three, etc., unless there is a special limitation. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices. The term "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " herein generally indicates that the associated objects before and after are in an "or" relationship.

[0051] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
