Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of cleaning machines, and more particularly, the present disclosure relates to a cleaning device; the present disclosure also relates to a cleaning base station and a cleaning system. BACKGROUND

[0002] With the progress of science and technology and the continuous improvement of living standards, people's demand for cleaning devices is increasing, and intelligent cleaning devices are becoming more and more common, such as commercial robots for cleaning in commercial environments such as shopping malls and office buildings.

[0003] Due to the limited battery capacity, the cleaning robot needs to be regularly moved to the base station for docking charging. Since the robot has a certain motion inertia, it will collide with the base station when docking, causing damage to the components. Especially for commercial robots, they are larger in size and have greater motion inertia, which is more likely to cause damage to the components due to collision. In order to avoid hard collision between the robot and the base station body as much as possible, the docking platform of the existing base station is mostly set as a telescopic buffer structure, and some buffer stroke is reserved. In the case that the elasticity of the buffer structure is small, hard collision may still occur. While in the case that the elasticity of the buffer structure is large, when the impact force of the robot is large, the rebound force of the buffer structure will be greater than the friction force between the robot and the ground after the robot stops moving, so the robot will be pushed out.

[0004] After the robot is pushed out, the contact area between the charging pads of the robot and the base station will be reduced. After the contact area of the pads of the two is reduced when docking, it will cause serious heating at the pads and other problems, and in severe cases, it will cause the robot and the base station to burn out, with disastrous consequences.

DETAILED DESCRIPTION

[0043] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement, numerical expressions and values of the components and steps set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0046] It is to be noted that like reference numerals and letters refer to like items in the following figures, and thus once an item is defined in one figure, it need not be discussed further in subsequent figures.

[0047] The specific embodiments of the present disclosure will be described hereinafter with reference to the accompanying drawings.

[0048] In this document, "up", "down", "front", "back", "left", "right", and the like are only used to indicate relative positional relationships among related parts, and do not limit the absolute positions of the related parts.

[0049] In this document, "first", "second", and the like are only used to distinguish between each other, and do not represent importance and order, and are not the premise of each other.

[0050] In this document, "equal", "same", and the like are not strictly limited in the mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and allowed in manufacturing or use.

[0051] The present disclosure provides a cleaning system, including a cleaning base station and a cleaning device, the cleaning device can be a self-moving cleaning robot, the cleaning base station is usually placed at a fixed location, and the cleaning device can return to the cleaning base station after completing the cleaning work. The cleaning base station can be integrated with functions such as charging, water replenishment, cleaning, drying, dust collection, and the like for the cleaning device.

[0052] The cleaning base station is provided with a first docking part, and the cleaning device is provided with a second docking part. The cleaning device is configured to be placed on the cleaning base station, and the second docking part can be matched with the first docking part. The cleaning system further includes a pressing mechanism, which is arranged on the cleaning base station or the cleaning device, and is configured to press the first docking part on the second docking part or the second docking part on the first docking part under the action of an external force.

[0053] When the cleaning device returns to the cleaning base station, it collides with the cleaning base station. After being impacted, the cleaning base station generates a counter thrust force on the cleaning device, which causes the cleaning device to be pushed away from the cleaning base station, or the first docking part and the second docking part cannot be completely matched, and the like.

[0054] The cleaning base station and the cleaning device can be charged and docked through the first docking part and the second docking part. For example, the first docking part and the second docking part are charging contacts, and after being matched together, the cleaning base station can charge the cleaning device. The pressing mechanism presses the first docking part and the second docking part to achieve complete contact docking, so as to avoid the problem of serious heating caused by the reduction of the charging contact area during the charging process, prevent the cleaning base station or the cleaning device from burning, and reduce the safety hazards of the cleaning system.

[0055] The cleaning base station and the cleaning device can be docked through the first docking part and the second docking part. For example, the first docking part and the second docking part are pipe joints, and after being matched together, the cleaning base station can supplement clean water to the cleaning device through the docked pipe. The pressing mechanism presses the first docking part and the second docking part to avoid water leakage at the connection of the two pipe joints.

[0056] For the convenience of understanding, the specific structure and working principle of the present disclosure will be described in detail below with reference to Figures 1 to 4 the embodiments.

[0057] As shown in Figure 1 , Figure 2 , the present disclosure provides a cleaning system, which comprises a cleaning base station 1, a cleaning device 2 and a pressing mechanism 3. The cleaning base station 1 is provided with a first docking part 11, and the cleaning device 2 is provided with a second docking part 21. The cleaning device 2 is provided with a rolling wheel or other walking assembly for walking, and the cleaning base station 1 is provided with a bottom plate for carrying the cleaning device 2. The cleaning device 2 can travel to the bottom plate of the cleaning device 2. When the cleaning device 2 returns to the cleaning base station 1 and collides with the cleaning base station 1, the cleaning base station 1 can be provided with a buffer mechanism. The buffer mechanism can buffer the impact of the cleaning device 2 through elastic action and generate a counter thrust force on the cleaning device 2.

[0058] When the cleaning device 2 returns to the cleaning base station 1, the second docking part 21 can be matched together with the first docking part 11. The pressing mechanism 3 can be arranged on the cleaning base station 1 or the cleaning device 2, and under the action of external force, the first docking part 11 and the second docking part 21 can be pressed together to make the first docking part 11 and the second docking part 21 stably matched. The pressing mechanism 3 can press the first docking part 11 and the second docking part 21 through pushing or pulling.

[0059] In some embodiments of the present disclosure, as Figure 1 , Figure 2As shown in FIG. 1, the pressing mechanism 3 is arranged on the cleaning device 2, and under the action of an external force, the second docking portion 21 is pushed to move towards the first docking portion 11, so as to press the second docking portion 21 against the first docking portion 11. Alternatively, the pressing mechanism 3 is arranged on the cleaning base station 1, and under the action of an external force, the first docking portion 11 is pushed to move towards the second docking portion 21, so as to press the first docking portion 11 against the second docking portion 21.

[0060] In some embodiments of the present disclosure, the pressing mechanism 3 is arranged on the cleaning device 2, and under the action of an external force, the first docking portion 11 is pulled to move towards the second docking portion 21, so as to press the first docking portion 11 against the second docking portion 21. Alternatively, the pressing mechanism 3 is arranged on the cleaning base station 1, and under the action of an external force, the second docking portion 21 is pulled to move towards the first docking portion 11, so as to press the second docking portion 21 against the first docking portion 11.

[0061] In detail, the first docking portion 11 is arranged on the side wall of the cleaning base station 1, and the second docking portion 21 is arranged on the side wall of the cleaning device 2. During the movement of the cleaning device 2 towards the cleaning base station 1, the second docking portion 21 can cooperate with the first docking portion 11 in the moving direction of the cleaning device 2. Moreover, the pressing mechanism 3 can press the first docking portion 11 and the second docking portion 21 in the moving direction of the cleaning device 2.

[0062] In order to avoid the cleaning device 2 being pushed away by the cleaning base station 1 due to excessive counter thrust when the cleaning device 2 is docked with the cleaning base station 1, the cleaning device 2 has a braking force that can overcome the counter thrust. The cleaning device 2 can generate the braking force through its own braking device, friction with the cleaning base station 1, etc.

[0063] In some embodiments of the present disclosure, the pressing force of the pressing mechanism 3 on the first docking portion 11 or the second docking portion 21 is less than the braking force of the cleaning device 2 on the cleaning base station 1, so as to avoid the pressing mechanism 3 pushing the cleaning device 2 away from the cleaning base station 1.

[0064] In an embodiment of the present disclosure, as shown in FIG. 1, Figure 3 、 Figure 4 The pressing mechanism 3 includes a pressing portion 31 and a transmission portion 32. The pressing portion 31 is located on the side of the second docking portion 21 away from the first docking portion 11, and is configured to be guided and cooperated on the cleaning device 2. The transmission portion 32 is configured to drive the pressing portion 31 to move towards the first docking portion 11 under the action of an external force, so as to press the second docking portion 21 against the first docking portion 11.

[0065] The pressing mechanism 3 is arranged on the cleaning device 2, the pressing part 31 is capable of moving towards or away from the cleaning device 2, the transmission part 32 is in transmission connection with the pressing part 31, and is capable of driving the pressing part 31 to move in a linear motion, swing, rotation or other ways. The transmission part 32 includes but is not limited to a lever, a pulley set, a connecting rod mechanism, or other transmission structures known to those skilled in the art.

[0066] In an embodiment of the present disclosure, as shown in Figure 3 、 Figure 4 The external force acting on the transmission part 32 is provided by the driving mechanism 4, and when the cleaning device 2 is placed on the cleaning base station 1, the driving mechanism 4 can drive the transmission part 32 to move to drive the pressing part 31 to press the second docking part 21 on the first docking part 11. In detail, the driving mechanism 4 can be arranged on the cleaning base station 1, or can be arranged on the cleaning base station 1. The driving mechanism 4 includes but is not limited to a driving motor, an electric push rod, an air cylinder, a hydraulic cylinder and the like.

[0067] As shown in the specific embodiment of Figure 3 、 Figure 4 To reduce the components of the cleaning device 2, the driving mechanism 4 can be arranged on the cleaning base station 1. When the cleaning device 2 is placed on the cleaning base station 1, the output end of the driving mechanism 4 extends towards the direction of the cleaning device 2, and drives the transmission part 32 of the pressing mechanism 3 to move to drive the pressing part 31 to extrude the second docking part 21.

[0068] In an embodiment of the present disclosure, as shown in Figure 3 、 Figure 4 The transmission part 32 of the pressing mechanism 3 includes a movable pulley set, the movable pulley set includes a movable pulley 321, a fixed pulley 322 and a flexible cable 323. The movable pulley 321 is guided and matched on the cleaning device 2, the fixed pulley 322 is rotatably connected on the cleaning device 2, and the flexible cable 323 is wound on the movable pulley 321 and the fixed pulley 322. Moreover, one end of the flexible cable 323 is fixedly connected on the pressing part 31, and the other end is fixedly connected on the cleaning device 2. The driving mechanism 4 can drive the movable pulley 321 to displace on the cleaning device 2, so that the flexible cable 323 drives the pressing part 31 to move towards the first docking part.

[0069] Based on the working principle of the movable pulley, the movement stroke of any point on the flexible cable is twice that of the movable pulley in the case of only one movable pulley. Therefore, the movement stroke of the pressing part 31 is twice that of the movable pulley 321. The transmission part 32 amplifies the output stroke of the driving mechanism 4 by two times, thereby saving half of the space of the pressing mechanism 3 and reducing the influence of the pressing mechanism 3 on the cleaning device. By cooperating the movable pulley 321 with the fixed pulley 322, the directions of the two ends of the flexible cable 323 can be changed to connect the pressing part 31 and the cleaning device 2 at the two ends of the flexible cable 323 in opposite directions, and the direction of the driving force is changed.

[0070] The movable pulley set includes at least one movable pulley 321. In some embodiments, the movable pulley set can be provided with two or more movable pulleys 321. The driving mechanism 4 can simultaneously push the movable pulleys 321 to displace on the cleaning device 2, thereby enabling the pressing mechanism 3 to save more space. Those skilled in the art can make corresponding settings to the structure of the movable pulley set based on the prior art, which will not be listed one by one here.

[0071] In detail, as shown in Figure 3 、 Figure 4 , the cleaning device 2 is provided with a guide part 324. The movable pulley 321 is cooperated with the cleaning device 2 through the guide part 324, and the driving mechanism 4 can push the movable pulley 321 to move along the guide part 324. The driving mechanism 4 can directly push the movable pulley 321 to move. Considering that the movable pulley 321 is a rotating part, the driving mechanism 4 can also indirectly push the movable pulley 321 to move to reduce the friction force on the movable pulley 321. For example, the movable pulley 321 can be arranged on the guide part 324 through a fixed seat, and the driving mechanism 4 pushes the fixed seat to drive the movable pulley 321 to move.

[0072] Since the movable pulley set can change the direction of the force, those skilled in the art can set the driving mechanism 4 to push the movable pulley 321 to move in other directions without creative labor.

[0073] In one embodiment of the present disclosure, as shown in Figure 3 、 Figure 4 , a reset device 5 is further arranged between the second docking part 21 and the pressing mechanism 3. The pressing mechanism 3 is configured to be reset under the elastic restoring force of the reset device 5 after the external force is removed. In detail, the pressing mechanism 3 can move in the direction of the first docking part 11 against the elastic action of the reset device 5 under the action of the driving mechanism 4. The reset device 5 can be a coil spring, a spring sheet or other conventional elastic element.

[0074] In one specific embodiment of the present disclosure, as shown in Figure 3 、 Figure 4As shown, the pressing part 31 of the pressing mechanism 3 comprises a pressing plate 311 which is guided and matched on the cleaning device 2, and a pressing block 312 which is fixedly connected on the pressing plate 311. The pressing block 312 is arranged on the pressing plate 311 in a position opposite to the second abutting part 21. The second abutting part 21 is arranged in a position opposite to the first abutting part 11 and the pressing block 312, and when the pressing part 31 moves towards the first abutting part 11, the second abutting part 21 is pressed by the pressing block 312 to be pressed on the first abutting part 11.

[0075] In one specific embodiment disclosed, Figure 3 , Figure 4 As shown, the cleaning device 2 has a shell 22, the second abutting part 21 can be arranged on the shell 22, and the reset device 5 can be arranged between the shell 22 and the pressing plate 311. In detail, the second abutting part 21 is arranged on the side wall of the shell 22 close to the cleaning base station 1, and the pressing part 31 and the transmission part 32 of the pressing mechanism 3 are arranged inside the shell 22. The driving mechanism 4 can extend into the shell 22 to drive the movable pulley 321 of the transmission part 32.

[0076] The reset device 5 is a spiral spring which is arranged on the side of the pressing plate 311 close to the second abutting part 21, and one end of which is matched with the inner side of the shell 22 and the other end of which is matched with the pressing plate 311. When the pressing plate 311 moves towards the first abutting part 11 under the action of the driving force, the spiral spring is compressed, and after the driving force is removed, the spiral spring pushes the pressing plate 311 back to the original position by the elastic force.

[0077] Alternatively, the spiral spring can also be arranged on the side of the pressing plate 311 away from the second abutting part 21, one end of which is matched with the inner side of the shell 22 and the other end of which is matched with the pressing plate 311. When the pressing plate 311 moves towards the first abutting part 11 under the action of the driving force, the spiral spring is stretched, and after the driving force is removed, the spiral spring pulls the pressing plate 311 back to the original position by the elastic force.

[0078] More specifically, as shown, Figure 3 , Figure 4 Figure 3 Figure 4 Both ends of the spiral spring can be detachably connected with the pressing plate 311 and the shell 22 through mounting seats, and a guide column can be sleeved in the spiral spring to limit the extension direction of the spiral spring. The transmission part 32 is arranged below the pressing block 312, and the spiral spring is arranged between the transmission part 32 and the pressing block 312.

[0079] In one embodiment of the present disclosure, the pressing block 312 is configured to extrude the shell 22 to deform, so as to press the second docking portion 21 against the first docking portion 11. Specifically, the shell 22 is made of a plastic or metal material with a certain elasticity, and is extruded by the pressing block 312 to deform outwardly, so as to press the second docking portion 21 against the first docking portion 11. When the pressing block 312 is reset under the action of the reset device 5, the shell 22 can return to the original shape by the elastic action.

[0080] In another embodiment of the present disclosure, the second docking portion 21 has a predetermined amount of movement on the shell 22, and the pressing block 312 is configured to extrude the second docking portion 21 to displace, so as to press the second docking portion 21 against the first docking portion 11. Specifically, the shell 22 is provided with a mounting hole for mounting the second docking portion 21, the second docking portion 21 can move in the mounting hole, and the second docking portion 21 is limited in the mounting hole by a limiting structure, so as to limit the movement of the second docking portion 21. The inner side of the second docking portion 21 facing the pressing block 312 and the outer side of the second docking portion 21 facing the first docking portion 11 are exposed from the mounting hole. The pressing block 312 can extrude the inner side of the second docking portion 21 under the action of the driving force, and the second docking portion 21 moves outwardly in the mounting hole and presses the first docking portion 11 through the outer side.

[0081] In one specific embodiment of the present disclosure, the first docking portion 11 and the second docking portion 21 are charging contacts, and the cleaning device 2 is configured to charge after the two charging contacts are docked. In detail, the first docking portion 11 and the second docking portion 21 are matched and conducted through surface contact, and if the contact area of the two is reduced, the resistance at the contact surface will increase, the current passing through will be too large, excessive heating will occur, the charging efficiency will be affected, and there will be a safety hazard.

[0082] The pressing mechanism 3 on the cleaning device 2 presses the second docking portion 21 against the first docking portion 11 under the action of an external force, which can make the second docking portion 21 completely fit the first docking portion 11, avoid the problem of overheating caused by the reduction of the contact area, maintain the charging efficiency, and reduce the safety hazard.

[0083] The present disclosure also provides a cleaning device which can be docked with the cleaning base station 1. The cleaning device includes a second docking portion 21 and a pressing mechanism 3. When the cleaning device is placed on the cleaning base station 1, the second docking portion 21 can be matched with the first docking portion 11 on the cleaning base station 1. The pressing mechanism 3 is arranged on the cleaning base station 1 and is configured to press the second docking portion 21 against the first docking portion 11 under the action of an external force. The specific structure and principle of the cleaning device are the same as those of the cleaning device of the cleaning system in the above embodiments, and therefore the present disclosure will not be described here again.

[0084] The present disclosure also provides a cleaning base station capable of being docked with the cleaning device 2 described above. The cleaning base station comprises a first docking portion 11 and a driving mechanism 4. The first docking portion 11 is configured to cooperate with the second docking portion 21 on the cleaning device 2. The driving mechanism 4 is configured to drive the pressing mechanism 3 so that the pressing mechanism 3 presses the second docking portion 21 on the first docking portion 11. The specific structure and principle of the cleaning base station are consistent with those of the cleaning base station of the cleaning system in the above-mentioned embodiments, and therefore the present disclosure will not be described here again.

[0085] The technical solutions adopted by the present disclosure will be described below in combination with specific application scenarios to help understanding. In the following application scenarios, the cleaning device is taken as a cleaning robot as an example.

[0086] Application scenario one

[0087] After working for a period of time, the cleaning robot returns to the cleaning base station 1 for charging. When the cleaning robot moves to dock with the cleaning base station 1, it collides with the cleaning base station 1, and the cleaning base station 1 generates a certain counter-thrust force on the cleaning device 2 after being hit.

[0088] The second docking portion 21 of the cleaning robot contacts and is conducted with the first docking portion 11 of the cleaning base station 1, and the cleaning base station 1 starts to charge the cleaning robot. The pressing mechanism 3 is arranged on the cleaning robot, the driving mechanism 4 on the cleaning base station 1 is extended, pushes the pressing mechanism 3 on the cleaning robot, the movable pulley 321 of the pressing mechanism 3 moves under the pushing of the driving mechanism 4, pulls the pressing plate 311 of the pressing mechanism 3 through the flexible cable, overcomes the elastic action of the reset device 5, moves towards the first docking portion 11, and the pressing block 312 arranged on the pressing plate 311 extrudes the second docking portion 21, which is arranged on the shell 22 of the cleaning robot, and the shell 22 is deformed outwardly under the action of the pressing block 312 to press the second docking portion 21 on the first docking portion 11.

[0089] The second docking portion 21 is pressed on the first docking portion 11 to ensure that the two docking portions for charging are completely contacted and docked, so as to avoid the problem of serious heating caused by the reduction of the contact area, thereby reducing the safety hazard.

[0090] After the cleaning robot is charged, it leaves the cleaning base station 1, the second docking portion 21 is separated from the first docking portion 11, the pressing mechanism 3 leaves the driving mechanism 4, and the pressing plate 311 and the pressing block 312 return to the original position under the elastic action of the reset device 5.

[0091] Application scenario two

[0092] After the cleaning robot works for a period of time, it returns to the cleaning base station 1 to charge.
