[0002] As a new self-moving cleaning equipment, self-moving lawn mowers are usually used for lawn mowing and maintenance in homes, parks, gardens, communities, and golf courses. Since self-moving lawn mowers can move and mow automatically without manual operation, they can reduce manpower, improve work efficiency, and maintain the stability of mowing height and quality, and are well received by customers.

[0003] Existing self-propelled lawn mowers are usually equipped with sensors such as cameras and rangefinders to collect image information or distance information on the route. However, residual weeds, sludge and other dirt are easily adsorbed to the surface of the sensor during the mowing process, causing the sensor to not work properly. Therefore, the base station equipped with the existing self-propelled lawn mower usually has a cleaning device to clean the sensor. However, the transmission structure used to drive the cleaning device equipped with the existing base station is complex and the cost is relatively high. In addition, it is difficult to keep the load of the motor that drives the cleaning device balanced. This can easily lead to unstable operation of the motor and a relatively high peak current, making the motor easily damaged. Summary of the invention

[0036] 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 of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0037] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0038] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0039] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0040] The specific embodiments of the present disclosure are described below in conjunction with the accompanying drawings.

[0041] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0042] In this article, "first", "second", etc. are only used to distinguish each other, and do not indicate the importance and order, or the premise of each other's existence.

[0043] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0044] The present disclosure provides a base station that can be used in conjunction with a self-moving device, which can be a lawn mowing robot, a cleaning robot, or other device that can move autonomously. The self-moving device can enter the base station for charging, cleaning, etc., depending on the type of the self-moving device. For example, when the self-moving device of the present disclosure is a self-moving lawn mowing device, the self-moving lawn mowing device can move on the lawn to complete automatic lawn mowing operations. When the self-moving lawn mowing device has finished mowing, it can enter the base station for docking. Not only can the self-moving lawn mowing device be charged through the base station, but the self-moving lawn mowing device can also be cleaned by a cleaning device provided on the base station.

[0045] Due to the working environment of the self-propelled lawn mower, various dirt such as dust and grass clippings may stick to the outer wall of the self-propelled lawn mower, especially fall on various sensors of the self-propelled lawn mower, thus affecting the normal use of the self-propelled lawn mower. When the self-propelled lawn mower enters the base station, the self-propelled lawn mower can be cleaned by the cleaning device on the base station, for example, weeds, dust and other dirt covering the sensors can be removed to ensure that each sensor can function normally.

[0046] Specifically, the base station disclosed in the present invention comprises at least a body and a cleaning device. The body is provided with a docking portion for the self-moving robot to dock; the cleaning device comprises a screw rotatably connected to the body, a driving mechanism for driving the screw to rotate, and a brush assembly matched with the screw, wherein the brush assembly is configured to reciprocate along the axial direction of the screw under the rotation of the screw to clean the self-moving device.

[0047] In this way, during the operation of the base station disclosed in the present invention, the screw can be driven to rotate by the driving mechanism, driving the brush body assembly on the screw to reciprocate along the axial direction of the screw to clean the self-moving device; and the driving mechanism can drive the screw to rotate at a uniform speed to make the brush move at a uniform speed.

[0048] It can be seen that the base station disclosed herein drives the brush body assembly to reciprocate through a screw rod. Not only is the overall transmission structure simple, the brush runs relatively smoothly, and the load of the driving mechanism is relatively balanced. During the entire working process, the peak current of the driving mechanism can remain stable, thereby extending the working life of the driving mechanism.

[0049] For ease of understanding, refer to Figures 1 to 8 , the specific structure and working principle of the base station and cleaning system disclosed in the present invention are explained in detail in combination with an embodiment.

[0050] like Figure 1 and Figure 2As shown, the present disclosure provides a base station, which can be used in conjunction with a self-moving device 5, and the self-moving device 5 can be a device that can move autonomously, such as a lawn mowing robot, a cleaning robot, etc. The self-moving device 5 can enter the base station for charging, cleaning, etc., depending on the type of the self-moving device 5. For example, when the self-moving device 5 of the present disclosure is a self-moving lawn mowing device, the self-moving lawn mowing device can move on the lawn to complete the automatic lawn mowing operation. When the self-moving lawn mowing device has finished mowing, it can enter the base station for docking. Not only can the self-moving lawn mowing device be charged through the base station, but the self-moving lawn mowing device can also be cleaned by a cleaning device provided on the base station.

[0051] It is understandable that due to the working environment of the self-moving lawn mower, various dirt such as dust and grass clippings may stick to the outer wall of the self-moving lawn mower, especially fall on various sensors of the self-moving lawn mower, thereby affecting the normal use of the self-moving lawn mower. When the self-moving lawn mower enters the base station, the self-moving lawn mower can be cleaned by the cleaning device on the base station, for example, weeds, dust and other dirt covering the sensors can be removed to ensure that each sensor can function normally.

[0052] Specifically, the base station of the present disclosure comprises at least a body 1 and a cleaning device. The body 1 is provided with a docking portion for the self-moving robot to dock. Figure 2 As shown, in one embodiment of the present disclosure, a receiving cavity 11 having an open end is provided on the body 1, and the open end is configured to allow the mobile device 5 to enter the receiving cavity 11, and the docking portion is the interior of the receiving cavity 11. Figure 2 As shown, in one embodiment of the present disclosure, the machine body 1 includes a frame 13 formed with a receiving cavity 11 , and a base 12 located in an area above the receiving cavity 11 , and a docking portion is disposed in the receiving cavity 11 .

[0053] like Figure 2 and Figure 3 As shown, the cleaning device includes a screw 23 rotatably connected to the body 1, a driving mechanism 24 driving the screw 23 to rotate, and a brush assembly 2 matched with the screw 23. Specifically, the brush assembly 2 may include a brush 22 and a sliding seat 21. The brush 22 is used to clean the sensor and other structures of the self-propelled mowing device. The brush 22 is installed on the sliding seat 21, and the sliding seat 21 is used to match with the screw 23. Specifically, a threaded hole is provided on the sliding seat 21, and the threaded hole is threadedly matched with the screw 23.

[0054] In this way, during the operation of the base station disclosed in the present invention, the screw 23 can be driven to rotate by the driving mechanism 24, thereby driving the brush body assembly 2 on the screw 23 to reciprocate along the axial direction of the screw 23 to clean the self-moving device 5; and the driving mechanism 24 can drive the screw 23 to rotate at a uniform speed, thereby causing the brush 22 to move at a uniform speed.

[0055] It can be seen that the base station disclosed in the present invention drives the brush body assembly 2 to reciprocate through the screw 23. Not only is the overall transmission structure simple, the operation of the brush 22 is relatively stable, and the load of the driving mechanism 24 is also relatively balanced. During the entire working process, the peak current of the driving mechanism 24 can remain stable, thereby extending the working life of the driving mechanism 24.

[0056] Specifically, in order to realize that the driving mechanism 24 drives the screw 23 to rotate, the brush assembly 2 on the screw 23 is driven to reciprocate along the axial direction of the screw 23, as shown in FIG. Figure 3 and Figure 4 As shown, in one embodiment of the present disclosure, a guide rod 25 parallel to the extending direction of the screw rod 23 is provided on the machine body 1 , and a guide hole cooperating with the guide rod 25 is provided on the sliding seat 21 .

[0057] Since the sliding seat 21 is provided with a guide hole that cooperates with the guide rod 25, and the extension direction of the guide rod 25 is parallel to the extension direction of the screw rod 23, the sliding seat 21 can reciprocate along the extension direction of the guide rod 25, and due to the limiting effect of the guide rod 25, the sliding seat 21 cannot rotate together with the screw rod 23. Therefore, during the rotation of the screw rod 23, the sliding seat 21 will not rotate with the screw rod 23, but will move along the extension direction of the guide rod 25; when the screw rod 23 rotates forward, the sliding seat 21 will move to one side along the extension direction of the guide rod 25, and when the screw rod 23 rotates reversely, the sliding seat 21 will move to the other side along the extension direction of the guide rod 25. In this way, the sliding seat 21 can be controlled to reciprocate along the extension direction of the guide rod 25 by the forward and reverse rotation of the screw rod 23.

[0058] Further, such as Figure 3 and Figure 4 As shown, in one embodiment of the present disclosure, there are two guide rods 25, which are respectively arranged on opposite sides of the screw rod 23. By arranging two guide rods 25 on opposite sides of the screw rod 23, it is possible to better ensure that the sliding seat 21 reciprocates along the extension direction of the guide rods 25 without deflecting to one side.

[0059] The driving mechanism 24 for driving the screw 23 to rotate may be a general rotary motor, which may directly drive the screw 23 to rotate, or may indirectly drive the screw 23 to rotate. Figure 2 and Figure 5As shown, in one embodiment of the present disclosure, the screw rod 23 is rotatably connected to the base 12; the driving mechanism 24 is fixed to the upper end of the base 12 and is configured to be drivingly connected to the screw rod 23. In this way, the space above the base 12 can be effectively utilized to arrange the driving mechanism 24, thereby reducing the occupied area of ​​the base station and improving the utilization efficiency of the space on the base station.

[0060] Specifically, Figure 3 and Figure 6 As shown, in one embodiment of the present disclosure, a driving pulley 241 is provided on the output shaft of the driving mechanism 24, and a driven pulley 231 is provided at one end of the screw rod 23, and a transmission belt 26 is wound around the driving pulley 241 and the driven pulley 231, so that the driving mechanism 24 can indirectly drive the screw rod 23 to rotate through the transmission belt 26. Moreover, the sizes of the driving pulley 241 and the driven pulley 231 can be set as needed, such as Figure 3 As shown, when the driving pulley 241 is smaller than the driven pulley 231, the torque requirement for the driving mechanism 24 can be effectively reduced, but the time required to control the movement of the brush 22 will be relatively long; and when the driving pulley 241 is larger than the driven pulley 231, the movement speed of the brush 22 can be increased, but the torque requirement for the driving mechanism 24 is relatively large.

[0061] Specifically, Figure 6 As shown, in one embodiment of the present disclosure, the brush 22 may include a first bristle 221 and a second bristle 222, wherein the first bristle 221 is disposed at the lower end of the brush 22 assembly, and the second bristle 222 is disposed at the side of the brush 22 assembly and is configured to face the opening direction of the accommodating cavity 11. The first bristle 221 is used to clean the top surface of the self-moving device 5, and the second bristle 222 is used to clean the front of the self-moving device 5.

[0062] In this way, during the operation of the base station disclosed in the present invention, the screw 23 can be controlled to rotate, thereby driving the screw 23 to rotate, and then driving the brush 22 to reciprocate in the accommodating chamber 11, so that the brush 22 can be docked on the self-moving device 5 in the accommodating chamber 11 for cleaning; and the driving mechanism 24 can drive the screw 23 to rotate at a uniform speed, so that the brush 22 moves at a uniform speed in the accommodating chamber 11.

[0063] Specifically, Figure 6 As shown, in one embodiment of the present disclosure, the sliding seat 21 extends from a position adjacent to the opening end to a side opposite to the opening end; the sliding seat 21 is configured to reciprocate in a direction perpendicular to its extension.

[0064] Since the sensors of the self-moving device 5 are mostly arranged on the front side or on the front of the self-moving device 5; when the self-moving device 5 enters the accommodating cavity 11 of the base station, the moving direction of the brush 22 can be perpendicular to the overall direction of the body of the self-moving device 5, that is, parallel to the surface where the sensor is located; in this way, the brush 22 can completely wipe the sensor on the self-moving device 5, thereby completely removing the weeds, dust and other dirt covering the sensor.

[0065] Further, such as Figure 7 As shown, in one embodiment of the present disclosure, a cover plate 14 is provided above the base 12, and the cover plate 14 is configured to cover the top of the base 12. By providing the cover plate 14, the top of the base 12 can be sealed to prevent dust, weeds or other foreign matter from entering other cavities of the frame 13 during cleaning.

[0066] Since the driving mechanism 24 has a certain volume, such as Figure 7 As shown, in one embodiment of the present disclosure, the cover plate 14 is provided with a convex cavity 141 adapted to at least part of the outer contour of the driving mechanism 24 at the position of the driving mechanism 24; an installation space for accommodating the driving mechanism 24 is formed between the convex cavity 141 and the base 12. The installation space formed between the convex cavity 141 and the base 12 can better fit the shape of the driving mechanism 24, thereby better accommodating the driving mechanism 24.

[0067] Further, such as Figure 6 As shown, in one embodiment of the present disclosure, the driving shaft of the driving mechanism 24 is configured to be higher than the height of the brush body assembly 2, and the driving mechanism 24 is connected to the screw 23 through a transmission mechanism. Since the driving shaft of the driving mechanism 24 is configured to be higher than the height of the brush body assembly 2, the driving device will not be within the movement range of the brush body assembly 2, and will not hinder the normal movement of the brush body assembly 2.

[0068] Further, such as Figure 4 and Figure 5As shown, in one embodiment of the present disclosure, a scraping portion 15 is provided on one side of the base 12, and the scraping portion 15 is located in the movement path of the brush 22 and is configured to interfere with the bristles of the brush 22. Since dirt may be attached to the bristles of the brush 22 after cleaning the self-moving device 5, by providing the scraping portion 15, the bristles of the cleaning device can interfere with the scraping portion 15, so that the scraping portion 15 can interfere with the bristles and squeeze the bristles to deform, thereby removing the dirt attached to the bristles. Specifically, the scraping portion 15 can be configured in the shape of a scraping ring, a scraping strip, etc., which is not specifically limited here. In this embodiment, the scraping portion 15 only interferes with the first bristles 221 of the brush 22, while in other embodiments of the present disclosure, the scraping portion 15 can interfere with both the first bristles 221 and the second bristles 222 of the brush 22, so as to achieve the purpose of scraping off the dirt attached to the first bristles 221 and the second bristles 222 at the same time.

[0069] In order to control the movement of the cleaning device of the present disclosure, as Figure 8 As shown, in one embodiment of the present disclosure, the base station of the present disclosure also includes a detection unit 3 and a control unit 4, wherein the brush body assembly 2 is constructed to trigger the detection unit 3 when it moves to a predetermined position; the control unit 4 is configured to control the screw 23 to change the rotation direction based on the electrical signal triggered by the detection unit 3, so as to change the moving direction of the brush body assembly 2, thereby making the brush body assembly 2 reciprocate between the first position and the second position.

[0070] In this way, the control unit 4 can control the screw 23 to change the rotation direction based on the electrical signal triggered by the detection unit 3 to change the moving direction of the brush body assembly 2, thereby making the brush body assembly 2 reciprocate between the first position and the second position, thereby achieving the purpose of cleaning the self-moving device 5.

[0071] Specifically, Figure 5 As shown, in one embodiment of the present disclosure, the detection unit 3 includes a first sensor 31 close to the first position and a second sensor 32 close to the second position; the brush body assembly 2 is configured to trigger the first sensor 31 when it moves to the first position, and trigger the second sensor 32 when it moves to the second position;

[0072] The control unit 4 is configured to control the driving mechanism 24 to drive the screw 23 to rotate in the opposite direction based on the electrical signal triggered by the first sensor 31 or the second sensor 32 .

[0073] In this way, during the operation of the base station disclosed in the present invention, the screw 23 can be controlled to rotate first to drive the brush assembly 2 to move in the direction of the first position; when the brush assembly 2 moves to the first position and triggers the first sensor 31, the control unit 4 controls the drive mechanism 24 to drive the screw 23 to rotate in the opposite direction based on the electrical signal triggered by the first sensor 31, thereby driving the brush assembly 2 to move in the direction of the second position; when the brush assembly 2 moves to the second position and triggers the second sensor 32, the control unit 4 controls the drive mechanism 24 to drive the screw 23 to rotate in the opposite direction based on the electrical signal triggered by the second sensor 32, thereby driving the brush assembly 2 to move in the direction of the first position. In this way, the brush assembly 2 can be reciprocated in the accommodating cavity 11.

[0074] The present disclosure also provides a cleaning system, including a self-moving device 5 and the aforementioned base station, the base station being configured to clean the self-moving device 5 through a cleaning device when the self-moving device 5 is docked at the docking portion of the body 1. The specific structure and application principle of the base station are the same as those described above, and the structure of the base station is not described in detail here. During the operation of the base station in the cleaning system of the present disclosure, the screw 23 can be driven to rotate by the driving mechanism 24, driving the brush body assembly 2 on the screw 23 to reciprocate along the axial direction of the screw 23 to clean the self-moving device 5; the overall transmission structure is simple, the operation of the brush 22 is relatively stable, and the load of the driving mechanism 24 is relatively balanced. During the entire working process, the peak current of the driving mechanism 24 can remain stable, thereby extending the working life of the driving mechanism 24.

[0075] Application Scenario

[0076] The present disclosure provides a base station, which can be used in conjunction with a self-moving device 5. The self-moving device 5 can be a lawn mowing robot, a cleaning robot, or other autonomously movable device.

[0077] Specifically, the base station of the present disclosure includes at least a body 1 and a cleaning device. The body 1 is provided with a docking portion for the self-moving robot to dock. The cleaning device includes a screw 23 rotatably connected to the body 1, a driving mechanism 24 for driving the screw 23 to rotate, and a brush body assembly 2 that cooperates with the screw 23. Specifically, the brush body assembly 2 may include a brush 22 and a sliding seat 21, the brush 22 is used to clean the sensor and other structures of the self-moving mowing equipment, the brush 22 is mounted on the sliding seat 21, and the sliding seat 21 is used to cooperate with the screw 23. Specifically, a threaded hole is provided on the sliding seat 21, and the threaded hole is threadedly matched with the screw 23.

[0078] In this way, during the operation of the base station disclosed in the present invention, the screw 23 can be driven to rotate by the driving mechanism 24, thereby driving the brush body assembly 2 on the screw 23 to reciprocate along the axial direction of the screw 23 to clean the self-moving device 5; and the driving mechanism 24 can drive the screw 23 to rotate at a uniform speed, thereby causing the brush 22 to move at a uniform speed.

[0079] It can be seen that the base station disclosed in the present invention drives the brush body assembly 2 to reciprocate through the screw 23. Not only is the overall transmission structure simple, the operation of the brush 22 is relatively stable, and the load of the driving mechanism 24 is also relatively balanced. During the entire working process, the peak current of the driving mechanism 24 can remain stable, thereby extending the working life of the driving mechanism 24.

[0080] Specifically, in order to realize the rotation of the screw 23 through the driving mechanism 24 and drive the brush body assembly 2 on the screw 23 to reciprocate along the axial direction of the screw 23, a guide rod 25 parallel to the extension direction of the screw 23 is provided on the body 1, and a guide hole matching the guide rod 25 is provided on the sliding seat 21.

[0081] Since the sliding seat 21 is provided with a guide hole that cooperates with the guide rod 25, and the extension direction of the guide rod 25 is parallel to the extension direction of the screw rod 23, the sliding seat 21 can reciprocate along the extension direction of the guide rod 25, and due to the limiting effect of the guide rod 25, the sliding seat 21 cannot rotate together with the screw rod 23. Therefore, during the rotation of the screw rod 23, the sliding seat 21 will not rotate with the screw rod 23, but will move along the extension direction of the guide rod 25; when the screw rod 23 rotates forward, the sliding seat 21 will move to one side along the extension direction of the guide rod 25, and when the screw rod 23 rotates reversely, the sliding seat 21 will move to the other side along the extension direction of the guide rod 25. In this way, the sliding seat 21 can be controlled to reciprocate along the extension direction of the guide rod 25 by the forward and reverse rotation of the screw rod 23.
