Description

Technical Field

[0001] The present application belongs to the technical field of cleaning equipment, and specifically provides a base station for a cleaning robot. Background Art

[0002] As people's living standards improve, cleaning robots have begun to be widely used. As a smart home appliance, cleaning robots can automatically move around the room using driving wheels and mop or vacuum the surface to be cleaned during movement.

[0003] To make cleaning robots more convenient for users, some existing cleaning robots are also equipped with a base station for charging. The base station has charging terminals, and the cleaning robot has power receiving terminals. The cleaning robot can automatically locate the base station and dock there. The power receiving terminals and charging terminals of the cleaning robot are then docked to charge the cleaning robot. Furthermore, the base station also has positioning slots for accommodating the driving wheels of the cleaning robot, which can locate the charging position of the cleaning robot and stabilize the cleaning robot in this position.

[0004] However, after entering the positioning slot, the cleaning robot's overall descent causes gravitational potential energy to be converted into kinetic energy, resulting in a significant impact force on the charging terminal when the cleaning robot docks with it, which can easily damage the charging terminal. Furthermore, if the cleaning robot deviates slightly from the charging position, it will lose contact with the charging terminal. Although the positioning slot can provide some stability for the cleaning robot during charging, when subjected to external disturbances, the cleaning robot will still wobble in the positioning slot, causing intermittent loss of contact between the cleaning robot and the charging terminal, which is not conducive to normal use of the charging terminal. Summary of the Invention

[0005] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem that the cleaning robot is easily out of contact with the charging terminal, the present application provides a base station for a cleaning robot, including a base station body and a base, the base station body is provided with a charging terminal, the base is provided with an inclined guide surface to guide the cleaning robot to dock, the cleaning robot includes a power receiving terminal and a driving wheel docked with the charging terminal, the power receiving terminal is provided on the side wall of the cleaning robot, the guide surface is provided with a positioning groove, the driving wheel moves to the edge of the positioning groove, the power receiving terminal contacts the charging terminal, the driving wheel is parked in the positioning groove, and the power receiving terminal presses against the charging terminal to make the charging terminal move rearward and downward relative to the base station body.

[0006] Optionally, the driving wheel moves to the edge of the positioning groove, and the driving motor of the driving wheel stops working, so that the cleaning robot slides to the bottom of the positioning groove under the action of gravity.

[0007] Optionally, the driving wheel moves to the edge of the positioning groove, the power receiving terminal contacts the charging terminal, and the driving wheel decelerates and enters the positioning groove.

[0008] Optionally, one end of the charging terminal is pivotally connected to the base station body, and the other end of the charging terminal is in contact with the power receiving terminal of the cleaning robot; or

[0009] The base station body is provided with an inclined slide rail, and the charging terminal slides along the slide rail to move forward and backward and up and down relative to the base station body.

[0010] Optionally, an elastic reset member is provided between the aforementioned charging terminal and the aforementioned base station body, so that the aforementioned charging terminal, which is detached from the docking with the aforementioned cleaning robot, automatically returns to its initial position.

[0011] Optionally, the power receiving terminal is provided on a side wall of the cleaning robot, the base station is further provided with a cleaning tank, the cleaning robot is provided with a cleaning device, and the cleaning tank accommodates the cleaning device to clean the cleaning device.

[0012] Optionally, the base station is provided with a water retaining member, which is arranged between the bottom of the charging terminal and the cleaning tank; the cleaning robot is provided with a first abutment portion, and the water retaining member and the first abutment portion are sealedly abutted together to isolate the cleaning liquid in the cleaning tank below the water retaining member.

[0013] Optionally, a baffle is provided at the bottom of the cleaning robot, and a second abutment portion is provided on the base station. The cleaning robot docked on the base station cooperates with the baffle and the second abutment portion to block the cleaning liquid escaping from the cleaning tank.

[0014] Optionally, the length of the water retaining member protruding from the base station body is greater than the length of the charging terminal protruding from the base station body, so that the water retaining member contacts the cleaning robot before the charging terminal.

[0015] Optionally, the cleaning robot is provided with a dirt collecting box and a dirt discharge port, and the base station is further provided with a dirt collecting device and a dirt collecting port, and the dirt collecting port is docked with the dirt discharge port to transfer the dirt in the dirt collecting box to the dirt collecting device.

[0016] Those skilled in the art will appreciate that the aforementioned base station for a cleaning robot in this application has at least the following beneficial effects:

[0017] By movably positioning the charging terminal on the base station body, the charging terminal can dock with the cleaning robot when the cleaning robot's drive wheel reaches the edge of the positioning groove. The charging terminal then moves rearward and downward relative to the base station body as the cleaning robot moves in the positioning groove. During the charging process, even if the cleaning robot shakes due to external disturbances, the charging terminal can move with the movement of the cleaning robot, thereby always maintaining a close docking with the cleaning robot and not easily losing contact. Furthermore, the charging terminal can move as the cleaning robot moves in the positioning groove, thereby dissipating the cleaning robot's kinetic energy, helping to reduce the impact force caused by the cleaning robot on the charging terminal and protecting the charging terminal.

[0018] Furthermore, the base station is provided with a cleaning tank that can clean the cleaning device of the cleaning robot, thereby making the base station more comprehensive and improving the user experience. However, since the cleaning tank has a certain depth, the base height of the base station increases accordingly. Therefore, in order for the cleaning robot to be able to travel to the top of the cleaning tank, the guide surface needs to be set with a larger inclination. The cleaning robot on the guide surface is in an inclined state. When the driving wheel of the cleaning robot enters the positioning groove, the entire robot drops down and returns to a horizontal state. While returning to a horizontal state, the cleaning robot needs to dock with the charging terminal. This causes the charging terminal to be simultaneously subjected to the impact force and friction generated by the descent of the cleaning robot, exacerbating the damage to the charging terminal. Moreover, in the process of the base station cleaning the cleaning device of the cleaning robot, the cleaning robot will also shake, resulting in continuous friction between the cleaning robot and the charging terminal, causing the charging terminal to be worn and causing the cleaning robot and the charging terminal to intermittently lose contact. By movably arranging the charging terminal on the base station body, the charging terminal can dock with the cleaning robot when the driving wheel of the cleaning robot moves to the edge of the positioning groove. Then, the charging terminal moves as the cleaning robot moves in the positioning groove, making the two relatively stationary, thereby effectively reducing the impact force of the cleaning robot on the charging terminal and the friction between the charging terminal and the charging terminal during the descent process, thereby protecting the charging terminal. In addition, when the base station is cleaning the cleaning device of the cleaning robot, the charging terminal in contact with the cleaning robot can move as the cleaning robot shakes, thereby remaining relatively stationary with the cleaning robot, thereby reducing the friction between the cleaning robot and the charging terminal, protecting the charging terminal, and ensuring close contact between the charging terminal and the cleaning robot.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0037] The base station for a cleaning robot of the present application includes a base station body and a base. The base station body is provided with a charging terminal, and the base is provided with an inclined guide surface to guide the cleaning robot to dock. The cleaning robot includes a power receiving terminal and a driving wheel docked with the charging terminal. The guide surface is provided with a positioning groove. The driving wheel moves to the edge of the positioning groove, the power receiving terminal contacts the charging terminal, the driving wheel stops in the positioning groove, and the power receiving terminal presses against the charging terminal to move the charging terminal rearward and downward relative to the base station body.

[0038] The base station of the present application movably arranges the charging terminal on the base station body, so that the charging terminal can dock with the cleaning robot when the driving wheel of the cleaning robot moves to the edge of the positioning groove. Then, the charging terminal moves backward and downward relative to the base station body as the cleaning robot moves in the positioning groove. During the charging process, even if the cleaning robot shakes due to external disturbances, the charging terminal can move with the movement of the cleaning robot, thereby always maintaining a close docking with the cleaning robot and not easily losing contact. In addition, the charging terminal can move as the cleaning robot moves in the positioning groove, thereby dissipating the kinetic energy of the cleaning robot, helping to reduce the impact force caused by the cleaning robot on the charging terminal and protecting the charging terminal.

[0039] It should be noted that the base station of the present application may have only a charging function, or may also have a function of cleaning the cleaning device of the cleaning robot or a function of collecting dust from the dirt collection box of the cleaning robot.

[0040] Optionally, the power receiving terminal is provided at the bottom or top of the cleaning robot. Preferably, the power receiving terminal is provided on the side wall of the cleaning robot.

[0041] The specific structure of the base station of the cleaning robot of the present application is described below with reference to the accompanying drawings.

[0042] The first embodiment of this application:

[0043] like Figure 1 As shown, the cleaning robot 1 of this embodiment includes a body 11 and a cleaning device 12 and a driving wheel 13 disposed at the bottom of the body 11. The cleaning robot 1 is also provided with a dirt collection box (not shown) and a dust suction port 14. The cleaning device 12 is a cleaning turntable. The cleaning robot 1 moves by itself on the driving wheel 13. During the movement, the cleaning turntable is used to mop and clean the surface to be cleaned, and the garbage is sucked into the dirt collection box through the dust suction port 14.

[0044] It should be noted that the cleaning device 12 can also be in various forms such as a cleaning roller, a translationally movable tray, or a stationary tray.

[0045] like Figure 2 and Figure 3As shown, the base station 2 of this embodiment includes a base station body 21 and a base 22. The base 22 is used to guide the cleaning robot 1 to dock with the base station 2. The base 22 is provided with a guide surface 221 and a positioning groove 222. During the docking process with the base station 2, the cleaning robot 1 first advances along the inclined guide surface 221 and then enters the positioning groove 222. When the cleaning robot 1 is stable in the positioning groove 222, it docks with the base station 2. A cleaning groove 23 is also provided on the base 22. The base 21 is provided with a charging terminal 31, a sewage collection device and a sewage collection port (not shown in the figure). The cleaning robot 1 is provided with a sewage discharge port (not shown in the figure) connected to the sewage collection box. When the cleaning robot 1 and the base station 2 are docked, the cleaning device 12 of the cleaning robot 1 is located in the cleaning groove 23 to clean the cleaning device 12 of the cleaning robot 1. The sewage collection port is connected to the sewage discharge port to transfer the sewage in the sewage collection box to the sewage collection device. At the same time, the power receiving terminal is provided on the side wall of the cleaning robot, and the power receiving terminal of the cleaning robot 1 abuts against the charging terminal 31 to charge the cleaning robot 1 .

[0046] It should be noted that the base station body 21 and the base 22 can be integrally formed or can be separate structures fixed together.

[0047] Continue as Figure 3 As shown, specifically, the charging terminal 31 includes a positive charging terminal 311 and a negative charging terminal 312 , and the positive charging terminal 311 and the negative charging terminal 312 are respectively connected to the cleaning robot 1 .

[0048] like Figure 4 As shown, further, the charging terminal 31 and the base station body 21 are movably connected. Taking one of the charging terminals 31 as an example (the positive charging terminal 311 and the negative charging terminal 312 have the same structure), the charging terminal 31 is a columnar structure with a certain length, and the charging terminal 31 includes a main body 313 and a protrusion 314. One end of the main body 313 is pivotally connected to the base station body 21, so that the charging terminal 31 can rotate around the pivot axis 315, thereby moving back and forth and up and down relative to the base station body 21. Preferably, on the basis of the pivotal connection between the charging terminal 31 and the base station body 21, the charging terminal 31 as a whole can move back and forth relative to the base station body 21. A protrusion 314 is provided at the other end of the main body 313, and the charging terminal 31 abuts against the power receiving terminal of the cleaning robot 1 through the protrusion 314 to charge the cleaning robot 1. Preferably, the raised portion 314 is provided with rounded surfaces 3141 around it and is movably connected to the main body 313 (for example, via a universal joint), so that the center of the raised portion 314 can smoothly dock with the cleaning robot 1 .

[0049] Although not shown in the figures, in a preferred implementation of this embodiment, a torsion spring serving as an elastic reset member is provided between the charging terminal 31 and the pivot shaft 315 of the base station body 21. When the charging terminal 31 rotates from the initial position, the torsion spring will rotate, thereby providing the charging terminal 31 with a force to restore to the initial position, so that the charging terminal 31 and the cleaning robot 1 are more closely abutted. At the same time, the charging terminal 31 automatically returns to the initial position after being out of contact with the cleaning robot 1, so as to facilitate abutment with the cleaning robot 1 again.

[0050] Although not shown in the figures, in a preferred implementation of this embodiment, corresponding magnetic components are provided on the charging terminal 31 and the cleaning robot 1. The mutual attraction of the magnetic components can assist in the docking of the charging terminal 31 and the cleaning robot 1. Moreover, when the cleaning robot 1 and the charging terminal 31 are docked, the two are adsorbed together by the magnetic component, so that the charging terminal 31 and the power receiving terminal of the cleaning robot 1 are docked more tightly.

[0051] It should be noted that when a magnetic attraction component is provided, an elastic reset component can be provided between the charging terminal 31 and the base station body 21; or the elastic reset component may not be provided. When the cleaning robot 1 leaves the base station 2, the charging terminal 31 can be reset under the adsorption action of the cleaning robot 1.

[0052] like Figure 3 and Figure 4 As shown, a water retaining member 24 is provided between the charging terminal 31 and the cleaning tank 23. The water retaining member 24 is a flexible strip-shaped structure. The cleaning robot 1 is provided with a first abutting portion (not shown in the figure). The first abutting portion can be an integral part of the cleaning robot 1, or a detachably connected structure. The shape of the water retaining member 24 matches the first abutting portion so that the water retaining member 24 can abut against the cleaning robot 1, thereby preventing the cleaning liquid in the cleaning tank 23 from splashing onto the charging terminal 31 when cleaning the cleaning device 12 of the cleaning robot 1. Preferably, the length of the water retaining member 24 protruding from the base station body 21 is greater than the length of the charging terminal 31 protruding from the base station body 21, so that the water retaining member 24 abuts against the cleaning robot 1 before the charging terminal 31.

[0053] Reference Figure 1 and Figure 3As shown, a baffle 15 is provided on the rear side of the suction port 14 of the cleaning robot 1, and a second abutment portion 223 is provided on the base 22. The second abutment portion 223 is a concave arc-shaped pit. When the cleaning robot 1 cleans the surface to be cleaned, the baffle 15 contacts the surface to be cleaned. The baffle 15 can prevent the side brush or roller brush of the cleaning robot 1 from pushing the dirt on the surface to be cleaned to the rear of the suction port 14, and prevent the air behind the suction port 14 from entering the suction port 14, so that the air enters the suction port 241 from the front, left and right sides of the suction port 14, so that the cleaning robot 1 can provide sufficient suction to the surface to be cleaned. Figure 5 As shown, after the driving wheel 13 enters the positioning groove 222, the cleaning robot 1 sinks, causing the baffle 15 to descend along with the cleaning robot 1 to abut against the second abutting portion 223, so that the baffle 15 can block the dirty liquid thrown out by the cleaning device 12 of the cleaning robot 1, thereby preventing the dirty liquid from flowing into the dust suction port 14 of the cleaning robot 1 and contaminating the dust suction port 14. Preferably, the baffle 15 abutting against the second abutting portion 223 is in a compressed state, so that the baffle 15 presses against the second abutting portion 223 to ensure the reliability of the seal between the two.

[0054] The following combination Figure 1-Figure 7 The process of docking the cleaning robot 1 with the base station 2 is described below:

[0055] First, the cleaning robot 1 on the surface to be cleaned travels onto the guide surface 221 and moves forward along the guide surface 221. The cleaning robot 1 on the guide surface 221 is in an inclined state. As the cleaning robot 1 moves on the guide surface 221, the cleaning robot 1 first abuts against the water retaining member 24. Then, the cleaning robot 1 continues to move forward, squeezing the water retaining member 24 and deforming the water retaining member 24. When the cleaning robot 1 moves to the edge of the positioning groove 222 (when it is about to enter the positioning groove 222 or has already entered a small part of the positioning groove 222), the power receiving terminal of the cleaning robot 1 and the charging terminal 31 (positive charging terminal 311 and negative charging terminal 312) abut (such as Figure 6 As shown), then, as the driving wheel 13 of the cleaning robot 1 moves in the positioning groove 222, the movement state of the cleaning robot 1 is forward and downward, and gradually returns to a horizontal state. During this period, the charging terminal 31 abutting against the cleaning robot 1 rotates downward around the pivot shaft 315 driven by the cleaning robot 1, and the protrusion 314 of the charging terminal 31 moves backward and downward relative to the base station body 21 (as shown). Figure 6 Shown location to Figure 7 As shown in the position), the protrusion 314 and the power receiving terminal of the cleaning robot 1 are kept in close contact. Figure 6As shown, when the cleaning robot 1 is stabilized at the lowest point of the positioning groove 222, the cleaning device 12 of the cleaning robot 1 is located at the cleaning groove 23, the first abutting portion of the cleaning robot 1 is tightly abutted against the water retaining member 24, and the baffle 15 at the bottom of the cleaning robot 1 is tightly abutted against the second abutting portion 223 (as shown in FIG. Figure 5 As shown), at the same time, the rotating charging terminal 31 drives the torsion spring to rotate, thereby giving the charging terminal 31 a chance to return to its initial position (by Figure 7 The position shown is restored to Figure 6 The force of the charging terminal 31 squeezes the cleaning robot 1 and promotes the tightness of the docking between the two. Then, the cleaning device 12 of the cleaning robot 1 is cleaned in the cleaning tank 23. The liquid under the cleaning robot 1 is blocked by the body 11 and the water retaining member 24 and does not splash onto the charging terminal 31. Moreover, the baffle 15 and the second abutting portion 223 are in close contact, which can block the dirty liquid thrown out by the cleaning device 12 and prevent the dirty liquid from flowing to the suction port 14 of the cleaning robot 1. At the same time, the base station 2 charges the cleaning robot 1. When charging is completed or the cleaning work is completed, as the cleaning robot 1 leaves the base station 2, the charging terminal 31 is reset under the action of the torsion spring force, and the water retaining member 24 is also reset under the action of its own elastic force.

[0056] Those skilled in the art will appreciate that the cleaning tank 23 provided on the base station 2 allows for cleaning the cleaning device 12 of the cleaning robot 1. While this enhances the functionality of the base station 2 and improves the user experience, the depth of the cleaning tank 23 increases the height of the base station 22. Therefore, to enable the cleaning robot 1 to reach the top of the cleaning tank 23, the guide surface 221 must be steeply inclined. The cleaning robot 1 is tilted on the guide surface 221. When the driving wheel 13 of the cleaning robot 1 enters the positioning slot 222, the robot lowers and returns to a horizontal position. While returning to a horizontal position, the robot docks with the charging terminal 31. This causes the charging terminal 31 to be subjected to both the impact and frictional forces generated by the robot's descent, which can easily damage the charging terminal 31. Furthermore, the cleaning of the cleaning device 12 by the base station 2 can cause the robot 1 to shake, resulting in constant friction between the robot 1 and the charging terminal 31, causing wear and intermittent disengagement.

[0057] Therefore, by movably setting the charging terminal 31 on the base station body 21, the charging terminal 31 can dock with the cleaning robot 1 when the driving wheel 13 of the cleaning robot 1 moves to the edge of the positioning groove 222 (when it is about to enter the positioning groove 222 or has entered a small part of the positioning groove 222), and then the charging terminal 31 moves as the cleaning robot 1 moves in the positioning groove 222, so that the two are relatively stationary, thereby effectively reducing the impact force of the cleaning robot 1 on the charging terminal 31 during the descent process and the friction between the charging terminal 31, thereby protecting the charging terminal 31. In addition, during the process of the base station 2 cleaning the cleaning device 12 of the cleaning robot 1, the charging terminal 31 abutting the cleaning robot 1 can move as the cleaning robot 1 shakes, thereby maintaining relative stillness with the cleaning robot 1, thereby reducing the friction between the cleaning robot 1 and the charging terminal 31, protecting the charging terminal 31, and ensuring close contact between the charging terminal 31 and the cleaning robot 1.

[0058] Furthermore, the positive charging terminal 311 and the negative charging terminal 312 can respectively abut against the cleaning robot 1 and move without affecting each other, so that the positive charging terminal 311 and the negative charging terminal 312 can respectively maintain close abutment with the cleaning robot 1, avoiding the situation where one terminal remains in contact while the other terminal loses contact.

[0059] It should be noted that, in one implementation of this embodiment, when the driving wheel 13 reaches the edge of the positioning groove 222, the driving motor of the driving wheel 13 stops working, so that the cleaning robot 1 slides to the bottom of the positioning groove 222 under the action of inertia and gravity. Alternatively, in one implementation of this embodiment, when the driving wheel 13 reaches the edge of the positioning groove 222, the driving wheel 13 decelerates and then enters the positioning groove 222. Both methods can reduce the kinetic energy of the cleaning robot 1 when entering the positioning groove 222, thereby further reducing the impact on the charging terminal 31 while ensuring that the docking with the base station 2 is completed.

[0060] In addition, it should be noted that the base station 2 of this embodiment may not be provided with the cleaning tank 23 and the dirt collecting device, that is, the base station 2 only has a charging function.

[0061] Those skilled in the art will appreciate that, in the case where the base station 2 only has a charging function, by movably setting the charging terminal 31 on the base station body 21, the charging terminal 31 can dock with the cleaning robot 1 when the driving wheel of the cleaning robot moves to the edge of the positioning groove 222 (when it is about to enter the positioning groove 222 or has already entered a small part of the positioning groove 222), and then the charging terminal 31 moves rearward and downward relative to the base station body 21 as the cleaning robot 1 moves in the positioning groove 222. During the charging process, even if the cleaning robot 1 shakes due to external disturbances, the charging terminal 31 can move with the movement of the cleaning robot 1, thereby always maintaining a close docking with the cleaning robot 1 and not easily losing contact. In addition, the charging terminal 31 can move as the cleaning robot 1 moves in the positioning groove 222, thereby dissipating the kinetic energy of the cleaning robot 1, helping to reduce the impact force caused by the cleaning robot 1 on the charging terminal 31, and protecting the charging terminal 31.

[0062] The second embodiment of the present application:

[0063] like Figure 8 As shown, unlike the first embodiment, the base station body 21 of this embodiment is provided with an inclined slide rail 316, and the charging terminal 31 can slide along the slide rail 316. Furthermore, a spring 317 serving as an elastic return member is provided between the charging terminal 31 and the base station body 21. When the charging terminal 31 slides along the slide rail 316, it compresses the spring 317, thereby providing a force for the charging terminal 31 to return to its initial position.

[0064] Combine Figures 8 to 10 As shown, first, the cleaning robot 1 on the surface to be cleaned travels onto the guide surface 221 and moves forward along the guide surface 221. The cleaning robot 1 on the guide surface 221 is in an inclined state. As the cleaning robot 1 moves on the guide surface 221, the cleaning robot 1 first abuts against the water retaining member 24. Then, the cleaning robot 1 continues to move forward, squeezing the water retaining member 24 and deforming the water retaining member 24. When the cleaning robot 1 moves to the edge of the positioning groove 222 (when it is about to enter the positioning groove 222 or has entered a small part of the positioning groove 222), the power receiving terminal and the charging terminal 31 (positive charging terminal 311 and negative charging terminal 312) of the cleaning robot 1 abut (as shown in FIG. Figure 9 As shown), then, as the driving wheel 13 of the cleaning robot 1 moves in the positioning groove 222, the motion state of the cleaning robot 1 is forward and downward, and gradually returns to a horizontal state. During this period, the charging terminal 31 abutting against the cleaning robot 1 slides along the slide rail 316 under the drive of the cleaning robot 1, and the charging terminal 31 moves backward and downward relative to the base station body 21 (as shown). Figure 9 Shown location to Figure 10The charging terminal 31 and the power receiving terminal of the cleaning robot 1 are kept in close contact. At the same time, the charging terminal 31 sliding along the slide rail 316 compresses the spring 317, thereby giving the charging terminal 31 a return to its initial position (by Figure 10 The position shown is restored to Figure 9 The force of the charging terminal 31 squeezes the cleaning robot 1, promoting the tightness of the docking between the two.
