[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] It should also be understood that the terminology used in this application specification is merely for describing specific realities within the scope of this application. It is important to understand that terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] like Figure 1 and Figure 2As shown, this application provides a self-moving robot, including a machine body 10 and a cutting mechanism 20. The cutting mechanism 20 is located at the bottom of the machine body 10 and is used to cut the object to be cut. The object to be cut includes, but is not limited to, grass on lawns, gardens, and paths. That is, the self-moving robot can cut grass on lawns to ensure the aesthetics of the lawn.

[0038] In one alternative implementation, the self-moving robot includes a vehicle body 11 and a walking component 12. A cutting mechanism 20 is disposed at the bottom of the vehicle body 11, and the walking component 12 is disposed on the vehicle body 11 to drive the vehicle body 11 to move, so that the vehicle body 11 can drive the cutting mechanism 20 to cut the grass on the lawn along a preset trajectory, thereby greatly reducing manual operation, saving time and effort, and truly freeing people from the labor of lawn maintenance.

[0039] In one alternative implementation, such as Figures 2 to 4 As shown, the cutting mechanism 20 includes a cutting component 21 and a driving component 24. The driving component 24 is connected to the cutting component 21 for transmission and is used to drive the cutting component 21 to cut the object to be cut, providing cutting power to the cutting component 21, greatly reducing manual operation, saving time and effort, and truly freeing people from the labor of lawn maintenance.

[0040] In an optional embodiment, the self-moving robot further includes a protective component 23 disposed at the bottom of the vehicle body 11. At least a portion of the cutting component 21 protrudes from the side of the protective component 23 away from the vehicle body 11 for cutting the object to be cut. The drive component 24 is disposed on the side of the protective component 23 away from the cutting component 21, allowing the protective component 23 to isolate the drive component 24 from the portion of the cutting component 21 exposed within the protective component 23. This prevents debris generated during cutting by the cutting component 21 from entering the bottom of the vehicle body 11. Such debris not only soils the bottom of the vehicle body 11, increasing its overall weight, but also affects the normal operation of the drive component 24, potentially causing motor stalling.

[0041] In an optional embodiment, a receiving structure 231 is formed on the protective component 23. The receiving structure 231 is used to partially cover the cutting component 21 and expose the working part of the cutting component 21 for cutting the object to be cut. The receiving structure 231 can be a through-hole structure or a groove structure on the protective component 23. This application does not limit the specific type of receiving structure. The main purpose is to ensure that at least a portion of the cutting component 21 can be accommodated in the receiving structure 231, while another portion of the cutting component 21 can be exposed from the receiving structure 231, so that the object to be cut can be cut. Simultaneously, it prevents debris generated during cutting from entering the inner side of the cutting component 21, effectively preventing debris from causing a decrease in the rotational speed of the drive component 24 or even causing it to stall.

[0042] In an optional implementation, the protective component 23 can move vertically relative to the vehicle body 11 to clean debris from the protective component 23, preventing debris accumulation that would increase the overall weight of the self-moving robot and even reduce the cutting efficiency of the cutting component 21. This also solves the problem of large amounts of debris accumulating at the bottom of the vehicle body 11, saving manpower and ensuring the self-moving robot remains unaffected during lawn mowing.

[0043] It should be noted that the debris includes, but is not limited to, grass clippings generated by the self-moving robot when mowing the lawn. These grass clippings tend to accumulate at the bottom of the vehicle body 11 when the cutting component 21 is cutting, which not only increases the overall weight of the self-moving robot, but also causes grass clippings to accumulate at the bottom of the vehicle body 11, affecting the rotation of the cutting component 21 and reducing the cutting efficiency.

[0044] For example, when the self-moving robot needs to clean debris from its bottom, it adjusts the position of the protective component 23 to its lowest point, allowing debris on the protective component 23 to be cleaned during the robot's movement. When the protective component 23 is in its lowest position, it can contact the object to be cut, or it can contact a cleaning component fixed to the grass, allowing the object to be cut or the cleaning component to clean the bottom of the self-moving robot. This quickly removes debris from the bottom of the vehicle body 11 without manual cleaning, resulting in fast and efficient cleaning. It also prevents debris buildup on the bottom of the self-moving robot, which could affect its normal operation or even damage it.

[0045] It should be noted that the cutting height can also be adjusted by adjusting the position of the protective component 23, and this application does not impose any limitations on this.

[0046] In one alternative implementation, such as Figures 2 to 5 As shown, the cutting mechanism 20 also includes a base 22, which is mounted on the bottom of the vehicle body 11. A protective component 23 is mounted on the side of the base 22 away from the vehicle body 11. A drive component 24 is located on the side of the protective component 23 facing the base 22. The cutting component 21 is exposed from the side of the protective component 23 away from the base 22, so that the protective component 23 can prevent the debris generated by the cutting component 21 during cutting from entering its side away from the base 22, thus avoiding affecting the drive component 24. Alternatively, the protective component 23 and the base 22 can work together to shield the debris generated by the cutting component 21 during cutting, preventing the debris from entering the interior of the self-moving robot, especially into the circuit area of ​​the self-moving robot, causing a short circuit in the circuit area.

[0047] In an optional embodiment, a receiving space is formed on the side of the base 22 away from the vehicle body 11, and the protective component 23 is received in the receiving space, so that the protective component 23 can form a gapless sliding fit with the inner wall of the receiving space. This not only prevents debris from entering the side of the protective component 23 facing the vehicle body 11 from the gap between the inner wall of the receiving space and the protective component 23, but also reduces the processing area of ​​the base 22 and reduces the process difficulty. While ensuring the sealing between the protective component 23 and the inner wall of the base 22, the protective component 23 can move up and down relative to the base 22 without gap.

[0048] In an optional embodiment, the base 22 includes a base plate 221 and side panels 222 connected to the periphery of the base plate 221. The base plate 221 is mounted on the bottom of the vehicle body 11. The side panels 222 and the base plate 221 enclose a receiving space, and the protective component 23 is received in the receiving space so that the side panels 222 can protect the protective component 23 and the cutting component 21 on the protective component 23.

[0049] For example, the side panel 222 can prevent other personnel from reaching their hands into the cutting component 21 through the gap between the self-moving robot and the ground when the cutting component 21 is performing the cutting action, thus preventing them from being cut by the cutting component 21; or, when the height of the obstacle on the ground (such as a rock, a metal can, or other hard obstacle) is greater than the height of the cutting component 21 off the ground, the side panel 222 can push the obstacle away when the self-moving robot is moving, or prevent the obstacle from entering the receiving space, thereby preventing the cutting component 21 from colliding with the obstacle and causing damage to the cutting component 21.

[0050] In one alternative implementation, such as Figures 2 to 8As shown, the protective component 23 includes a seal 23b and a protective disc 23a. The protective disc 23a is installed in the receiving space. The cutting component 21 is located on the side of the protective disc 23a away from the base plate 221. The seal 23b is located between the protective disc 23a and the side panel 222 to fill the gap between the protective disc 23a and the side panel 222, preventing the debris generated by the cutting component 21 from entering the side facing away from the base 22. At the same time, it will not affect the up and down movement of the protective disc 23a. It can also scrape off the sticky grass on the seal 23b when the protective component 23 is in the lowest position to prevent grass blockage.

[0051] In an optional embodiment, the outer contour of the protective disk 23a is adapted to the inner contour of the receiving space, and the sealing member 23b is arranged around the outer periphery of the protective disk 23a and abuts against the inner side of the side plate 222. This not only effectively prevents debris from entering the side of the protective disk 23a facing the substrate 221 from the gap between the protective disk 23a and the side plate 222, but also reduces the processing area of ​​the protective disk 23a, reduces the process difficulty, and better ensures the fitting accuracy between the protective disk 23a and the side plate 222.

[0052] In an optional embodiment, the seal 23b includes at least one of a sealing strip and a sealing wool strip, which are received in a receiving space to fill the gap between the side panels 222 of the protective disc 23a, thereby effectively preventing debris generated by the cutting assembly 21 during cutting from entering its side facing away from the base 22, without affecting the vertical movement of the protective disc 23a relative to the receiving space.

[0053] For example, the seal 23b includes a sealing strip that is arranged around the outer periphery of the protective disc 23a. When the protective disc 23a is installed into the receiving space, the sealing strip abuts against the inner side of the side panel 222 to fill the gap between the protective disc 23a and the side panel 222. This effectively prevents the debris generated by the cutting assembly 21 during cutting from entering the side facing away from the base 22, without affecting the vertical movement of the protective disc 23a relative to the receiving space.

[0054] For example, the seal 23b includes a sealing strip, which is arranged around the outer periphery of the protective disc 23a. When the protective disc 23a is installed into the receiving space, the sealing strip abuts against the inner side of the side panel 222 to fill the gap between the protective disc 23a and the side panel 222. This effectively prevents the debris generated by the cutting assembly 21 during cutting from entering the side facing away from the base 22, and does not affect the up-and-down movement of the protective disc 23a relative to the receiving space.

[0055] It should be noted that the sealing strip includes, but is not limited to, the brush or bristle structure set on the protective plate 23a. Its main purpose is to fill the gap between the protective plate 23a and the side panel 222, prevent the debris generated by the cutting component 21 during cutting from entering the side facing away from the base 22, and at the same time, it should not affect the raising and lowering of the protective plate 23a.

[0056] In an optional embodiment, the protective disc 23a has a planar cutting surface 234, which is the side away from the substrate 221. At least a portion of the cutting component 21 is exposed from the cutting surface 234 for cutting the object to be cut. The cutting surface 234 is configured as a planar structure and adapted to the shape of the receiving space, allowing it to completely cover the cutting component 21 with the base 22. This not only prevents grass clippings from splashing onto the inside of the protective disc 23a during cutting, but also reduces grass clipping accumulation compared to a grooved cutting surface 234.

[0057] In an optional embodiment, the receiving structure 231 is formed on the cutting surface 234 and corresponds to the projected position of the cutting assembly 21, and the diameter of the receiving structure 231 is adapted to the outer diameter of the cutting assembly 21 to prevent the debris generated by the cutting assembly 21 during cutting from entering the side of the cutting assembly 21 facing away from the base 22 through the gap between the cutting assembly 21 and the protective disk 23a, while not affecting the rotation of the cutting assembly 21.

[0058] In an optional embodiment, the depth of the receiving structure 231 is adapted to the height of the connecting seat of the cutting assembly 21, so that the connecting seat of the cutting assembly 21 can be received in the receiving structure 231, and the cutting disc 211 of the cutting assembly 21 can be exposed from the receiving structure 231 to expose the cutting surface 234. This can effectively prevent debris from entering the inside of the cutting assembly 21 and causing the output shaft connected to the cutting assembly 21 to jam.

[0059] In one optional embodiment, the cutting assembly 21 includes a cutter head 211 and a cutting blade 212 for cutting the object to be cut. The cutter head 211 includes a connecting seat and a cutter head 211 body connected to the connecting seat. The connecting seat is drively connected to the output shaft of the drive assembly 24. The cutting blade 212 is mounted on the cutter head 211 body, enabling the drive assembly 24 to drive the cutter head 211 body and the cutting blade 212 to rotate via the connection between the output shaft and the connecting seat, thereby improving cutting efficiency and ensuring a neat cut of the lawn.

[0060] It should be noted that the drive assembly 24 can be, but is not limited to, a drive motor, and the cutter head 211 is connected to the output shaft of the drive motor.

[0061] In an optional embodiment, the outer diameter of the cutter head 211 is adapted to the inner diameter of the receiving structure 231 to prevent grass clippings from entering the inner side of the cutter head 211 through the gap between the cutter head 211 and the receiving structure 231, thereby avoiding the output shaft from jamming due to debris accumulation.

[0062] In an optional embodiment, the cutting diameter of the cutting blade 212 during the cutting action is not less than the diameter of the receiving structure 231. That is, one end of the cutting blade 212 is fixed on the cutter head 211, and the other end of the cutting blade 212 extends radially along the cutter head 211 to the outside of the receiving structure 231. In this way, not only can the object to be cut be cut, but also grass clippings can be prevented from entering the inner side of the cutter head 211 from the gap between the cutter head 211 and the receiving structure 231, thus avoiding the output shaft from jamming due to the accumulation of debris.

[0063] In an optional embodiment, the receiving structure 231 is two recessed structures 231a formed on the protective disc 23a, the maximum diameter of the recessed structure 231a being adapted to the diameter of the cutter head 211 so that at least a portion of the cutter head 211 can be disposed in the recessed structure 231a.

[0064] For example, the recessed structure 231a has a first groove 2311 and a second groove 2312, with the second groove 2312 located at the bottom of the first groove 2311. The inner diameter of the second groove 2312 is smaller than the inner diameter of the first groove 2311, and the outer diameter of the cutter disc 211 matches the outer diameter of the first groove 2311. This ensures that grass clippings do not enter the inner side of the cutter disc 211 through the gap between the cutter disc 211 and the receiving structure 231, while simultaneously ensuring that the cutter disc 211 can rotate relative to the protective disc 23a to perform the cutting action.

[0065] In an optional embodiment, the depth of the first groove 2311 is adapted to the thickness of the cutter head 211 body, and the connecting seat is connected to the drive assembly 24 and accommodated in the second groove 2312 to ensure that grass clippings do not enter the inner side of the cutter head 211 body from the gap between the cutter head 211 body and the first groove 2311, while ensuring that the cutter head 211 body can rotate relative to the protective disc 23a to perform the cutting action.

[0066] In an optional embodiment, a first protrusion 2111 is formed on the side of the cutter head 211 body facing the second groove 2312, and a second protrusion 233 is formed on the side of the second groove 2312 facing the cutter head 211 body. The first protrusion 2111 is arranged around the outside of the second protrusion 233 to prevent grass clippings from entering the inner side of the cutter head 211 body from the gap between the cutter head 211 body and the second groove 2312.

[0067] In an optional embodiment, the receiving structure 231 is two through-hole structures 231b formed on the protective disk 23a. The two through-hole structures 231b are spaced apart along the width direction of the vehicle body 11. The cutting components 21 are installed in each through-hole structure 231b respectively, so that the self-moving robot can drive the two cutting components 21 to cut the object to be cut, ensuring the cutting efficiency of the self-moving robot.

[0068] In an optional embodiment, the protective component 23 includes a protective member 232 disposed on the side of the protective disk 23a away from the substrate 221. At least a portion of the structure of the cutting component 21 is located inside the protective member 232, which can effectively prevent obstacles from entering the cutting component 21 from both sides of the protective disk 23a, thereby improving the safety of the cutting component 21.

[0069] In an optional embodiment, the protective member 232 includes a protective protrusion and a protective strip. The protective protrusion is disposed outside the protective strip, and at least a portion of the protective strip covers the cutting assembly 21 and is connected to the cutting surface 234 to prevent obstacles from entering the cutting assembly 21 from both sides of the protective disc 23a, thereby improving the safety of the cutting assembly 21.

[0070] In one alternative implementation, such as Figures 3 to 5 As shown, the protective disk 23a has a highest position and a lowest position and can reciprocate between the highest position and the lowest position. The cutting component 21 performs a cutting action when the protective disk 23a is in the highest position. The bottom of the machine body 10 performs a cleaning action when the protective disk 23a is in the lowest position, which avoids the accumulation of debris on the bottom of the machine body 10, reduces the frequency of manual maintenance, extends the service life of the self-moving robot, and also improves the working efficiency of the self-moving robot.

[0071] For example, such as Figure 3 As shown, when the protective disc 23a moves from the lowest position to the highest position, the self-moving robot can drive the cutting mechanism 20 to perform cutting operations on the object to be cut. The protective disc 23a can prevent grass clippings generated by the cutting mechanism 20 during grass cutting operations from entering the cutting component 21 and the machine body 10. The side panel 222 of the base 22 can prevent other personnel from reaching their hands into the cutting component 21 through the gap between the self-moving robot and the ground when the cutting component 21 is performing cutting operations, thus preventing them from being cut by the cutting component 21.

[0072] For example, such as Figure 4As shown, after the self-moving robot completes the mowing action, the protective disc 23a moves from the highest position to the lowest position so that the protective disc 23a can contact the object to be cut or the external cleaning component. This allows the object to be cut or the cleaning component to clean the bottom of the self-moving robot, thereby quickly removing debris from the protective disc 23a without manual cleaning. The cleaning speed is fast and efficient, preventing debris from accumulating on the bottom of the self-moving robot, which could affect the normal operation of the self-moving robot or even damage it.

[0073] In an optional embodiment, the protective disc 23a moves between the highest and lowest positions by a distance of 15 mm to 70 mm, so that the cutting mechanism 20 can perform cutting operations on the object to be cut when the protective disc 23a is in the highest position, and can perform cleaning when the protective disc 23a is in the lowest position to prevent debris from accumulating at the bottom of the vehicle body 11.
