Description

Technical Field

[0001] The present disclosure relates to the field of cleaning equipment, and more specifically, to a base station. Background Art

[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, due to the residual weeds, sludge and other foreign objects easily sticking to the sensors during the mowing process, the sensors cannot work properly. Therefore, the base station equipped with the existing self-propelled lawn mowers usually has a cleaning device to clean the sensors. However, during the operation of the base station, it is easy for the transmission mechanism driving the cleaning device to be contaminated with dirt, which can easily cause the cleaning device to fail to move normally and also reduce the service life of the transmission mechanism.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] The specific embodiments of the present disclosure are described below in conjunction with the accompanying drawings.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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, thus 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 perform its functions normally. However, during the operation of the base station, it is easy for the transmission mechanism driving the cleaning device to be contaminated with dirt, which can easily cause the cleaning device to fail to move normally and reduce the service life of the transmission mechanism.

[0045] The base station disclosed in the present invention comprises at least a machine body and a cleaning device. The machine body is provided with a docking portion for the self-moving device to dock; the cleaning device comprises a brush body assembly, a screw rod rotatably connected to the machine body, and a driving mechanism for driving the screw rod to rotate; the brush body assembly is provided with a threaded hole, the brush body assembly cooperates with the screw rod thread through the threaded hole, and the brush body assembly is configured to reciprocate along the axial direction of the screw rod under the rotation of the screw rod to clean the self-moving device docked at the docking portion; a chip removal space is provided between the screw rod and the threaded hole; the chip removal space is configured to extend along the axial direction of the screw rod.

[0046] During the operation of the base station disclosed in the present invention, by making the brush body assembly reciprocate along the axial direction of the screw under the rotation of the screw, the dirt attached to the screw and the threaded hole can be continuously discharged from the chip removal space between the screw and the threaded hole, thereby avoiding the dirt from adhering to the screw and the brush body assembly, ensuring that the cleaning device can work normally, and thus extending the service life of the base station.

[0047] For ease of understanding, refer to Figures 1 to 11 , 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.

[0048] like Figure 1 and Figure 2 As 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.

[0049] 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.

[0050] 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 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 .

[0051] like Figure 3 and Figure 4 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 body assembly 2 matched with the screw 23. A threaded hole 211 is provided on the brush body assembly 2, and the brush body assembly 2 is threadedly matched with the screw 23 through the threaded hole 211. 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 installed on the sliding seat 21. The sliding seat 21 is provided with a threaded hole 211, and the brush 22 is threadedly matched with the screw 23 through the threaded hole 211. In this way, during the working process of the base station disclosed in the present invention, the screw 23 can be driven to rotate by the driving mechanism 24, so as to drive the brush body assembly 2 on the screw 23 to reciprocate along the axial direction of the screw 23, so as to clean the self-moving equipment 5.

[0052] 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 .

[0053] 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.

[0054] 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.

[0055] 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 3 and Figure 5 As 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.

[0056] 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 6 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.

[0057] 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.

[0058] 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.

[0059] A chip removal space is provided between the screw 23 and the threaded hole 211; the chip removal space is configured to extend along the axial direction of the screw 23. During the operation of the base station of the present disclosure, by making the brush assembly 2 reciprocate along the axial direction of the screw 23 under the rotation of the screw 23, dirt attached to the screw 23 and the threaded hole 211 can be continuously discharged from the chip removal space between the screw 23 and the threaded hole 211, thereby preventing dirt from being attached to the screw 23 and the brush assembly 2, ensuring that the cleaning device can work normally, and further extending the service life of the base station.

[0060] Specifically, in one embodiment of the present disclosure, the chip removal space is a through groove 27 provided on the threaded hole 211 or the screw 23. Thus, during the operation of the base station of the present disclosure, by making the brush assembly 2 reciprocate along the axial direction of the screw 23 under the rotation of the screw 23, the dirt attached to the screw 23 and the threaded hole 211 can be continuously discharged from the through groove 27 between the screw 23 and the threaded hole 211, thereby preventing the dirt from being attached to the screw 23 and the brush assembly 2.

[0061] Further, such as Figure 8 and Fig. 9 As shown, in one embodiment of the present disclosure, the outer surface of the screw 23 is provided with a first threaded portion 232 extending axially, and the inner surface of the threaded hole 211 is provided with a second threaded portion 212 matching the first threaded portion 232; the second threaded portion 212 is recessed outward to form a through groove 27.

[0062] In this way, during the operation of the base station disclosed in the present invention, since the first threaded portion 232 on the screw 23 will rotate relative to the second threaded portion 212 on the sliding seat 21, the first threaded portion 232 on the screw 23 can continuously push the dirt attached to the screw 23 and the threaded hole 211 into the through groove 27, and be discharged from the through groove 27 on the second threaded portion 212, thereby achieving the purpose of cleaning the dirt attached to the screw 23 and the threaded hole 211.

[0063] like Fig. 9 As shown, in one embodiment of the present disclosure, the through groove 27 penetrates the opposite ends of the second threaded portion 212 in the axial direction thereof. In this way, it can be ensured that when the sliding seat 21 moves toward one end of the machine body 1 under the rotation of the screw 23, the dirt attached to the screw 23 or the threaded hole 211 can be discharged from one axial end of the screw 23 or the threaded hole 211, and when the sliding seat 21 moves toward the other end of the machine body 1 under the rotation of the screw 23, the dirt attached to the screw 23 or the threaded hole 211 can be discharged from the other axial end of the screw 23 or the threaded hole 211, thereby improving the sewage discharge efficiency of the through groove 27 and better avoiding the residual dirt on the screw 23 or the threaded hole 211.

[0064] And as Fig. 9 As shown, in one embodiment of the present disclosure, the radial depth of the through groove 27 is the same as the radial dimension of the second threaded portion 212 on the inner surface of the threaded hole 211. In this way, dirt can be better prevented from remaining in the threads of the second threaded portion 212, ensuring that all dirt can be discharged from the through groove 27 on the second threaded portion 212.

[0065] Further, such as Fig. 9 As shown, in one embodiment of the present disclosure, at least two through grooves 27 are provided, and at least two through grooves 27 are evenly distributed in the circumferential direction of the threaded hole 211. In this way, dirt attached to the screw 23 or the threaded hole 211 can be discharged from the multiple through grooves 27, thereby improving the dirt removal efficiency of the chip removal space and better avoiding dirt residue on the screw 23 or the threaded hole 211.

[0066] In another embodiment of the present disclosure, the first threaded portion 232 is recessed inward to form a through groove 27. In this way, during the operation of the base station of the present disclosure, the second threaded portion 212 on the threaded hole 211 continuously pushes the dirt attached to the screw 23 and the threaded hole 211 to be discharged from the through groove 27 on the first threaded portion 232, thereby also achieving the purpose of cleaning the dirt attached to the screw 23 and the threaded hole 211.

[0067] In other embodiments of the present disclosure, a through groove 27 can be provided on both the first threaded portion 232 and the second threaded portion 212 as a chip removal space, so that the first threaded portion 232 and the second threaded portion 212 can push each other to discharge dirt attached to the screw 23 and the threaded hole 211 from the through groove 27 provided on the other, thereby improving the dirt removal efficiency of the chip removal space.

[0068] And as Fig.10 and Fig.11 As shown, in another embodiment of the present disclosure, a partial area on the first threaded portion 232 is configured as a first flat area 233 , and a radial gap is provided between the first flat area 233 and the second threaded portion 212 , thereby forming a chip removal space.

[0069] Thus, during the operation of the base station of the present disclosure, since the first threaded portion 232 on the screw 23 rotates relative to the second threaded portion 212 on the sliding seat 21, the second threaded portion 212 on the sliding seat 21 can continuously push the dirt attached to the screw 23 and the threaded hole 211 to be discharged from the first flat area 233 on the first threaded portion 232, thereby achieving the purpose of cleaning the dirt attached to the screw 23 and the threaded hole 211. Moreover, compared with the through groove 27, the first flat area 233 is less difficult to process.

[0070] Further, such as Fig.10 As shown, in one embodiment of the present disclosure, the first flat area 233 extends along the axial direction of the first threaded portion 232. In this way, it can be ensured that when the sliding seat 21 moves toward one end of the body 1 under the rotation of the screw 23, the dirt attached to the screw 23 or the threaded hole 211 can be discharged from one axial end of the first flat area 233, and when the sliding seat 21 moves toward the other end of the body 1 under the rotation of the screw 23, the dirt attached to the screw 23 or the threaded hole 211 can be discharged from the other axial end of the first flat area 233, thereby improving the sewage discharge efficiency of the first flat area 233 and better avoiding the dirt remaining on the screw 23 or the threaded hole 211.

[0071] Further, such as Fig.11 As shown, in one embodiment of the present disclosure, at least two first flat areas 233 are provided, and the at least two first flat areas 233 are evenly distributed in the circumferential direction of the first threaded portion 232. In this way, dirt attached to the screw 23 or the threaded hole 211 can be discharged from the multiple first flat areas 233, thereby improving the dirt discharge efficiency of the chip discharge space and better avoiding dirt residue on the screw 23 or the threaded hole 211.

[0072] In another embodiment of the present disclosure, a partial area on the second threaded portion 212 is constructed as a second flat area, and a radial gap is provided between the second flat area and the first threaded portion 232, forming a chip removal space. Similarly, during the operation of the base station of the present disclosure, since the first threaded portion 232 on the screw 23 rotates relative to the second threaded portion 212 on the sliding seat 21, the first threaded portion 232 on the screw 23 can continuously push the dirt attached to the screw 23 and the threaded hole 211 to be discharged from the second flat portion on the second threaded portion 212, thereby achieving the purpose of cleaning the dirt attached to the screw 23 and the threaded hole 211. Moreover, compared with the through groove 27, the processing difficulty of the second flat area is also relatively low.

[0073] The present disclosure also provides a cleaning system, including a self-moving device 5 and the aforementioned base station, and the base station is configured to clean the self-moving device 5 through a cleaning device when the self-moving device 5 is parked at the parking portion of the machine body 1. The self-moving device 5 can be a self-moving lawn mower, a self-moving floor scrubber, a self-moving floor sweeper, or other self-moving cleaning devices; the base station is configured to clean the self-moving device 5 through a cleaning device when the self-moving device 5 is located at the parking portion. The specific structure and application principle of the base station are the same as those described above, and the structure of the base station will not be described in detail here.

[0074] The present disclosure also provides a transmission mechanism, including a screw 23 and a threaded hole 211 provided on the brush body assembly 2; the threaded hole 211 of the brush body assembly 2 is threadedly matched with the screw 23, and the brush body assembly 2 is constructed to reciprocate along the axial direction of the screw 23 under the rotation of the screw 23. A chip removal space is provided between the screw 23 and the threaded hole 211; the chip removal space is constructed to extend along the axial direction of the screw 23. The specific structure and application principle of the transmission mechanism are the same as those described above, and will not be described in detail here. It should be noted that the transmission mechanism of the present disclosure can be applied not only to the above-mentioned base station, but also to other structures, and can play the same role, which will not be described in detail here.

[0075] Application scenario 1

[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 mower robot, a cleaning robot, or other devices that can move autonomously. 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 device 5 to dock; the cleaning device comprises a brush body assembly 2, a screw 23 rotatably connected to the body 1, and a driving mechanism 24 for driving the screw 23 to rotate. The brush body assembly 2 is provided with a threaded hole 211, and the brush body assembly 2 is threadedly matched with the screw 23 through the threaded hole 211. The brush body assembly 2 is constructed to reciprocate along the axial direction of the screw 23 under the rotation of the screw 23 to clean the self-moving device 5 docked at the docking portion.

[0077] The outer surface of the screw rod 23 is provided with a first threaded portion 232 extending in the axial direction, and the inner surface of the threaded hole 211 is provided with a second threaded portion 212 matching the first threaded portion 232 ; the second threaded portion 212 is recessed outward to form a through groove 27 .

[0078] In this way, during the operation of the base station disclosed in the present invention, since the first threaded portion 232 on the screw 23 will rotate relative to the second threaded portion 212 on the sliding seat 21, the first threaded portion 232 on the screw 23 can continuously push the dirt attached to the screw 23 and the threaded hole 211 into the through groove 27, and be discharged from the through groove 27 on the second threaded portion 212, thereby achieving the purpose of cleaning the dirt attached to the screw 23 and the threaded hole 211.

[0079] Application scenario 2

[0080] 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 mower robot, a cleaning robot, or other devices that can move autonomously. 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 device 5 to dock; the cleaning device comprises a brush body assembly 2, a screw 23 rotatably connected to the body 1, and a driving mechanism 24 for driving the screw 23 to rotate. The brush body assembly 2 is provided with a threaded hole 211, and the brush body assembly 2 is threadedly matched with the screw 23 through the threaded hole 211. The brush body assembly 2 is constructed to reciprocate along the axial direction of the screw 23 under the rotation of the screw 23 to clean the self-moving device 5 docked at the docking portion.

[0081] Among them, the outer surface of the screw 23 is provided with a first threaded portion 232 extending axially, and the inner surface of the threaded hole 211 is provided with a second threaded portion 212 matching the first threaded portion 232; a partial area on the first threaded portion 232 is constructed as a first flat area 233, and there is a radial gap between the first flat area 233 and the second threaded portion 212, forming a chip removal space.

[0082] Thus, during the operation of the base station of the present disclosure, since the first threaded portion 232 on the screw 23 rotates relative to the second threaded portion 212 on the sliding seat 21, the second threaded portion 212 on the sliding seat 21 can continuously push the dirt attached to the screw 23 and the threaded hole 211 to be discharged from the first flat area 233 on the first threaded portion 232, thereby achieving the purpose of cleaning the dirt attached to the screw 23 and the threaded hole 211. Moreover, compared with the through groove 27, the first flat area 233 is less difficult to process.

[0083] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the marketplace, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein. The scope of the present disclosure is defined by the appended claims.
