Description

Technical Field

[0001] This application relates to the field of robotics, and more particularly to a mobile device. Background Technology

[0002] The development of automated mobile devices is rapid, and their application scenarios are expanding. Automated mobile devices, such as lawnmowers, can automatically perform tasks on lawns, such as mowing, fertilizing, and watering, making them essential robots for home lawn maintenance. However, lawnmowers have weak boundary handling capabilities, especially for boundaries that cannot be crossed, such as those with walls, fences, or cliffs. This forces users to manually manage the lawn edges, resulting in a poor user experience. Existing lawnmowers address this issue by adding an extra lawn-manipulating mechanism; however, current technology lacks a reliable way to retract and protect this mechanism, reducing the ease of use and lifespan of the mobile device. Therefore, how to effectively store and protect the lawn-manipulating mechanism is a problem that urgently needs to be solved. Utility Model Content

[0003] This application provides a mobile device, including a main body and a lawn care mechanism. By providing a receiving section and a working component in the lawn care mechanism, the receiving section is used to store, limit, and protect the working component, which helps to extend the service life of the working component and improve the ease of use of the mobile device.

[0004] In a first aspect, embodiments of this application propose a mobile device, including a device body and a lawn care mechanism. The lawn care mechanism is disposed at at least one end of the device body along the travel direction of the mobile device and is electrically connected to the device body. The lawn care mechanism includes a working part and a receiving part. The working part is movably connected to the receiving part, and the receiving part is used to store the working part. The working part can move away from the receiving part when performing operations.

[0005] This application embodiment provides a receiving section and a working component in the lawn care mechanism. The receiving section is used to store and limit the working component. When the working component is in the stored state, it is not working and is in a good protective state, which helps to extend the service life of the working component and prevents the lawn care mechanism from exceeding the main body of the equipment when it is not working, thus avoiding obstruction of the movement of the mobile device.

[0006] In one possible implementation, the lawn care mechanism further includes a drive component and a transmission component. The drive component is electrically connected to the main body of the equipment. One end of the drive component is connected to the transmission component, and the other end of the transmission component is connected to the working part. The drive component is used to drive the working part to extend from the receiving section to the outside of the main body of the equipment, and also to retract the working part back into the receiving section. The drive component's ability to extend the working part from the receiving section to the outside of the main body, and to retract the working part into or near the receiving space when not in operation, improves the mobility of the mobile equipment in complex terrain. The transmission component enhances the reliability and stability of the connection between the working part and the drive component, improves the overall compactness of the working part's structure, is suitable for the layout of long and narrow lawn care mechanisms on mobile equipment, and facilitates the disassembly of the working part, reducing maintenance costs.

[0007] In one possible implementation, the receiving section has an opening facing outwards. A drive component is used to move the workpiece away from the receiving section through the opening, and also to retract the workpiece back into the receiving section through the opening. In the operating state, at least a portion of the workpiece can extend out of the equipment body through the opening from within the receiving section, thus isolating the workpiece's working area from the mobile device's wheels and preventing any impact on the mobile device's motion control. In the non-operating state, the workpiece can retract into the receiving section through the opening, thereby improving the mobile device's mobility in complex terrain and enhancing the safety and reliability of the workpiece's operation.

[0008] In one possible implementation, the drive component, transmission component, working component, and opening are arranged sequentially along the width direction of the equipment body, which is perpendicular to the plane formed by the travel direction and the height direction of the equipment body. This allows the drive component to directly drive the transmission component, causing the working component to move linearly relative to the equipment body in the extension direction of the equipment body. This results in a simple structure and improves the transmission efficiency and positioning accuracy of the lawn care mechanism. Secondly, by setting the working component to extend laterally relative to the equipment body, the working component can enter areas that mobile equipment cannot reach, such as under bushes and on the sides of steps, improving the lawn care effect. Furthermore, the laterally extended working component can better approach vertical obstacles such as walls, tree trunks, or fences, improving the edge trimming effect and avoiding problems such as missed mowing or collision damage.

[0009] In one possible implementation, the opening faces outward along the travel direction of the mobile device; the drive component drives the workpiece from one end of opposite ends in the width direction of the device body to the other end of opposite ends in the width direction of the device body through the opening. By setting the opening on the side of the receiving part away from the device body along the travel direction of the mobile device, the workpiece can be moved efficiently and accurately to the working position with simple structural components, while avoiding collision damage to the workpiece from obstacles on the side of the mobile device, which helps to extend the service life of the lawn care mechanism.

[0010] In one possible implementation, the opening includes a first opening and a second opening. The first opening faces outward along a direction perpendicular to the travel direction of the mobile device, and the second opening faces outward along the travel direction of the mobile device, with the second opening intersecting the first opening. A driving component drives a transmission component to pass sequentially through the second opening and the first opening, so that the workpiece moves from at least one end of the device body along the travel direction to the side of the device body. This allows the lawn care mechanism to efficiently and accurately move the workpiece to the work position using simple structural components, while further extending the workpiece beyond the device body, thus expanding the effective working range of the lawn care mechanism.

[0011] In one possible implementation, the lawn care mechanism includes a mounting shell and a mounting base, with at least a portion of the mounting shell and at least a portion of the mounting base forming a receiving section; a drive component is located on the side of the mounting base opposite to the main body of the equipment. This helps to further prevent external interference to the working parts and further improves the overall integrity of the product.

[0012] In one possible implementation, a partial mounting shell and a partial mounting base enclose a receiving space, where the drive component and transmission component are located. The receiving space and the housing portion are situated at opposite ends of the width of the main body of the equipment. The receiving space prevents external interference to the drive component, further enhancing the safety and overall integrity of the lawn care mechanism. The spacing between the receiving space and the housing portion prevents debris attached to the working components from entering the receiving space, avoiding debris contamination of functional components such as the drive component. This improves the stability and reliability of the lawn care mechanism's functional components and reduces cleaning difficulty.

[0013] In one possible implementation, the receiving section has a groove, and the workpiece at least partially abuts against the inner wall of the groove along the height direction of the device body. This allows the receiving section to counteract the gravity of the workpiece, eliminating its tendency to drop vertically to the ground, limiting its position, and ultimately achieving a good storage effect.

[0014] In one possible implementation, when the workpiece is working away from the receiving section, its working range is tangent to or separate from the edge of the receiving section. This reduces the risk of damage to the mounting housing caused by the rotation of the workpiece, and avoids the problem of insufficient rotational momentum of the cutting unit in the working area, which reduces the trimming quality.

[0015] In one possible implementation, the lawn care facility includes a work head for repairing lawns outside the travel path of the mobile equipment. For example, by rotating the work head to break grass blades and stems at the left and right front edges of the mobile equipment, efficient lawn maintenance on areas where boundaries cannot be crossed can be achieved.

Detailed Implementation

[0028] For ease of understanding, the relevant technical terms involved in the embodiments of this application will be explained and described below.

[0029] In the description of the embodiments in this application, unless otherwise stated, "multiple" means two or more.

[0030] The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Features specified as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0031] The directional terms mentioned in the embodiments of this application, such as "upper," "lower," "front," "back," "left," "right," "inner," "outer," "side," "top," and "bottom," are only for reference to the directions in the accompanying drawings. These directional terms are used to better and more clearly explain and understand the embodiments of this application, and are not intended to explicitly or implicitly suggest that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, etc., and therefore should not be construed as limiting the embodiments of this application.

[0032] The development of automated mobile devices is rapid, and their application scenarios are expanding. Automated mobile devices, such as lawnmowers, can automatically perform tasks on lawns, such as mowing, fertilizing, and watering, making them essential robots for home lawn maintenance. However, lawnmowers have weak boundary handling capabilities, especially for boundaries that cannot be crossed, such as those with walls, fences, or cliffs. This forces users to manually manage the lawn edges, resulting in a poor user experience. Existing lawnmowers address this issue by adding an extra lawn-manipulating mechanism; however, current technology lacks a reliable way to retract and protect this mechanism, reducing the ease of use and lifespan of the mobile device. Therefore, how to effectively store and protect the lawn-manipulating mechanism is a problem that urgently needs to be solved.

[0033] This application provides a mobile device that includes a lawn care mechanism with a working component and a storage space on its main body. The storage space is used to store the working component, and the working component is used to move away from the storage space when performing operations.

[0034] Figure 1 This is a schematic diagram of the structure of the mobile device 1000 provided in this application embodiment in a non-operational state. (See attached diagram.) Figure 1The mobile device 1000 includes a device body 100 and a lawn care mechanism 200. The lawn care mechanism 200 is located at at least one end of the device body 100 along the travel direction of the mobile device 1000. The two ends of the device body 100 along the travel direction can be the front and rear ends, respectively. That is, the lawn care mechanism 200 can be located at the front end, the rear end, or both. This avoids the problem of the lawn care mechanism 200 restricting the mobility of the mobile device 1000 by being externally mounted on the side of the device body 100. Furthermore, installing the lawn care mechanism 200 at the front and / or rear end of the device body 100 facilitates maintenance, reduces the space occupied by the lawn care mechanism 200 on the device body 100, and improves the overall compactness of the mobile device 1000. For example, in this embodiment, the lawn care mechanism 200 is installed at the front end of the device body 100, thereby giving the device body 100 a forward impact function, reducing the impact force on the device body 100, and extending its service life. The lawn care mechanism 200 is electrically connected to the device body 100. Schematically, the lawn care mechanism 200 and the device body 100 can be electrically connected through conductive components, such as conductive cables and conductive connectors, and obtain driving power through the power supply 120. Thus, the mobile device 1000 can care for the lawn using the lawn care mechanism 200, such as watering, fertilizing, and weeding. This process is fully automated by the lawn care mechanism 200, requiring no additional manual handling by the user, reducing the user's workload and improving the user experience.

[0035] The mobile device 1000 may include, but is not limited to, handheld devices, riding devices, and fully automated intelligent devices, etc., and this application does not limit it in this regard. The mobile device 1000 can move on the ground. For example, the mobile device 1000 can move on the ground when pushed by a user. Alternatively, the mobile device 1000 may have its own mobility. Specifically, the mobile device 1000 includes drive wheels, which allow it to move automatically on the ground. The mobile device 1000 may be configured as, but is not limited to, cleaning equipment, lawnmowers, crop harvesters, etc., and this application embodiment does not limit it. The mobile device 1000 also includes multiple wheels 110. Exemplarily, in this embodiment, the number of wheels 110 is set to four, namely two first wheels 1101 and two second wheels 1102. Two first wheels 1101 are rotatably disposed at the front end of the device body 100 in the length direction X of the mobile device 1000 and located on both sides of the device body 100 in the width direction Y of the mobile device 1000. Two second wheels 1102 are rotatably disposed at the rear end of the device body 100 in the length direction X of the mobile device 1000 and located on both sides of the device body 100 in the width direction Y of the mobile device 1000.

[0036] In this embodiment, the lawn care mechanism 200 is detachably mounted on the main body 100. This facilitates, on the one hand, the maintenance, replacement, and cleaning of the various parts of the lawn care mechanism 200 without disassembling the entire main body, and allows for separate transportation of the lawn care mechanism 200 and the main body, improving transportation and installation convenience. On the other hand, it enables flexible switching between different lawn care mechanisms 200; for example, the main body 100 can switch between different lawn care mechanisms 200 according to different tasks, improving the flexibility of the mobile device 1000 in switching tasks and enriching the application scenarios of the mobile device 1000. Of course, in some embodiments, the lawn care mechanism 200 may be non-detachably connected to the main body 100; this embodiment does not impose specific limitations.

[0037] For the sake of accuracy, all references to direction in this article should be expressed in terms of direction. Figure 1For reference, the term "length direction X" can refer to the forward or backward direction of the mobile device 1000; or the arrangement direction of the first wheel 1101 and the second wheel 1102 in the mobile device 1000; or it can also refer to the arrangement direction of the device body 100 and the lawn care mechanism 200, i.e., the front-back direction (where the positive X-axis is forward). The term "width direction Y" refers to the arrangement direction of the two first wheels 1101 or the two second wheels 1102 in the mobile device 1000, i.e., the left-right direction (where the positive Y-axis is left). The term "height direction Z" refers to the direction from the supporting plane of the mobile device 1000 to the highest protruding part of the mobile device 1000, i.e., the up-down direction (where the positive Z-axis is up). The length direction X, width direction Y, and height direction Z together constitute the three orthogonal directions of the mobile device 1000. For ease of description, the up-down, left-right, and front-back orientations in this embodiment are relative positions and do not constitute a limitation on implementation. For illustrative purposes, in this embodiment, the mounting component 30 has a long, narrow shape. The extension direction of the mounting component 30 is parallel to the width direction Y of the mobile device 1000. The length direction X, width direction Y, and height direction Z of the mobile device 1000 can be customized according to the specific structure of the product and the viewing angle presented in the accompanying drawings, and this application does not impose specific limitations. Of course, in some embodiments, the extension direction of the mounting component 30 can also be set at an angle to the width direction Y of the mobile device 1000, and this application embodiment does not impose specific limitations.

[0038] Figure 2 yes Figure 1 A bottom view of the mobile device 1000 in operation mode, combined with Figure 1 and Figure 2As shown, the lawn care mechanism 200 includes a mounting component 30 and a working component 50. The mounting component 30 is mounted on the main body 100 of the mobile device 1000. The working component 50 is located on the side of the mounting component 30 opposite to the main body 100, i.e., along the travel direction of the mobile device 1000, i.e., the length direction X, the main body 100, the mounting component 30, and the working component 50 are arranged sequentially. The working component 50 includes a working part 52 and an elastic part 53. One end of the elastic part 53 is mounted on the mounting component 30, and the other end of the elastic part 53 is connected to the working part 52. The working part 52 is rotatable relative to the mounting component 30 in three-dimensional space. The lawn care mechanism 200 provided in this application embodiment has two main advantages. Firstly, the working component 52 can deflect according to different force directions, enhancing its adaptability to complex terrains such as walls, fences, slopes, or uneven ground. This improves the flexibility and precision of the lawn care work, eliminating the need for manual edge treatment by the user, thus enhancing the user experience and reducing labor intensity by avoiding frequent movement of the mobile device 1000. Secondly, the elastic component 53 provides the power to move the working component 52 back to its initial position, thereby reducing the rigid impact on the working component 52, preventing damage due to excessive deflection angle, and automatically returning the working component 52 to its initial position. This prevents over-trimming or missed trimming when the working component 52 is used as a cutting structure, enhancing the safety and reliability of the working component 52. Indicatively, the elastic component 53 can be configured as at least one of a spring, sheet metal, bellows, or elastomer. The elastomer can be a rubber column, plastic column, silicone column, etc. For example, in this embodiment, the elastic element 53 is configured as a spring, thereby facilitating the elastic restoring capability of the elastic element 53. It is understood that when the elastic element 53 is configured as a bellows or an elastomer, grass clippings are prevented from getting stuck on the elastic element 53, reducing the cleaning difficulty and service life of the elastic element 53.

[0039] Combination Figure 1 and Figure 2 As shown, exemplarily, in this embodiment, the elastic member 53 is configured as a spring. The elastic member 53 is cylindrical in shape. When the mobile device 1000 moves along the length direction X of the mobile device 1000, the working member 50 extends from the accommodating empty member beyond the mounting member 30 to perform operations. One end of the spring is connected to the working member 52, so the working member 52 can deflect according to different force directions. For example, when an obstacle in the traveling direction of the mobile device 1000 presses against the working member 52, the working member 52 will deflect backward; when an obstacle in the reversing direction of the mobile device 1000 presses against the working member 52, the working member 52 will deflect forward; when an obstacle at the bottom of the mobile device 1000 presses against the working member 52, the working member 52 will deflect upward.

[0040] Figure 3This is a schematic diagram of the lawn care facility provided in this application in its non-operational state, combined with... Figure 1 , Figure 2 and Figure 3 As shown, the lawn care mechanism 200 includes a working component 52 and a receiving section 300. The receiving section 300 has a storage space 303, which communicates with the outside world, i.e., with the external space of the lawn care mechanism 200. The working component 52 is movably connected to the receiving section 300, which is used to store the working component 52. That is, when the lawn care mechanism 200 is in a non-working state, the working component 52 is located within the receiving space 303; when the lawn care mechanism 200 is in a working state, the working component 52 moves from the receiving space 303 to the external space to perform operations, i.e., the working component 52 can move away from the receiving section 300 when performing operations. In this embodiment, by providing a receiving section 300 in the lawn care mechanism 200 to store and limit the working component 52, the working component 52 is not working in the stored state and is in a good protected state, which helps to extend the service life of the working component 52 and prevents the lawn care mechanism 200 from exceeding the equipment body 100 when in a non-working state, thus avoiding obstruction of the movement of the mobile device 1000.

[0041] Combination Figure 1 , Figure 2 and Figure 3 As shown, in one possible implementation, the receiving part 300 has a groove 3031, and the working part 52 at least partially abuts against the inner wall of the groove 3031 along the height direction Z of the device body 100. This allows the receiving part 300 to counteract the gravity of the working part 52, eliminate the tendency of the working part 52 to drop to the ground, limit the working part 52, and ultimately achieve a good storage effect.

[0042] Figure 4 yes Figure 3 The schematic diagram of the cross-sectional structure of the lawn care facility 200 shown is combined with... Figure 1 , Figure 3 and Figure 4 As shown, in one possible embodiment, the mounting component 30 includes a mounting base 31 and a mounting housing 32. At least a portion of the mounting housing 32 and at least a portion of the mounting base 31 together form a receiving portion 300. Specifically, Figure 4 The shown receiving portion 300 is formed by the mounting base 31 along its width direction Y and the mounting housing 32 along its width direction Y. Figure 4The shown housing 300 has a semi-open storage space 303. In this embodiment, the housing 300 with storage space 303 is formed by the mounting shell 32 and the mounting base 31. After the workpiece 52 finishes its work, it can be driven back into the storage space 303, avoiding interference from the external environment and preventing the workpiece 52 from falling off the mounting component 30, thereby further improving the structural integrity of the mobile device 1000.

[0043] Figure 5 yes Figure 3 The diagram shown is an exploded view of the lawn care facility 200, combined with... Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in one possible embodiment, the lawn care mechanism 200 further includes a drive component 60. The drive component 60 is disposed on the side of the mounting base 31 opposite to the main body 100, and is located within the accommodating space 301 formed by the mounting housing 32 and the mounting base 31. In one possible embodiment, the accommodating space 301 and the receiving portion 300 are located at opposite ends of the width direction Y of the main body 100. This prevents debris attached to the working part 50 from entering the accommodating space 301, avoiding the problem of debris contaminating functional components such as the drive component 60, improving the stability and reliability of the working performance of the functional components of the lawn care mechanism 200, and reducing cleaning difficulty. The accommodating space 301 can prevent the drive component 60 from being interfered with externally, which is beneficial to further improving the safety and integrity of the lawn care mechanism 200. The drive component 60 is electrically connected to the main body 100. The drive component 60 is used to drive the working part 52 to extend from the receiving portion 300 to the outside of the main body 100, and the drive component 60 is also used to retract the working part 52 back into the receiving portion 300. In this embodiment, by placing the drive component 60 within the accommodating space 301, grass clippings and mud can be prevented from entering and acting on the drive component 60, thereby improving the reliability of the transmission and extending its service life. Furthermore, when not in operation, the working part 52 can be retracted into or near the accommodating space 301 to be retrieved into the receiving part 300, thus improving the mobility of the mobile device 1000 in complex terrain.

[0044] Combination Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, in one possible embodiment, the lawn care mechanism 200 further includes a transmission component 70. The transmission component 70 is connected to the drive component 60 and the elastic member 53. The transmission component 70 and the working component 52 are arranged sequentially in the extending direction of the mounting component 30. The drive component 60 is connected to one end of the transmission component 70 along the length direction X, and the other end of the transmission component 70 along the length direction X is connected to the working component 52. Thus, the arrangement of the transmission component 70 improves the reliability and stability of the connection between the working component 50 and the drive component 60, enhances the overall compactness of the working component 50's structure, making it suitable for the elongated lawn care mechanism 200 layout of the mobile device 1000, and facilitates the disassembly of the working component 52, reducing maintenance costs.

[0045] Combination Figure 1 , Figure 4 and Figure 5 As shown, in one possible implementation, the transmission component 70, the elastic element 53, and the working component 52 are arranged sequentially in the extending direction of the mounting component 30. Thus, on the one hand, the elastic element 53 can absorb the instantaneous impact force during the operation of the working component 52, reducing the risk of damage to the transmission component 70 and the drive component 60; on the other hand, it improves the overall compactness of the working component 50 structure, making it suitable for the narrow layout of the lawn care mechanism 200 of the mobile device 1000, and facilitating the disassembly of the working component 52, reducing maintenance costs. The elastic element 53 needs to have a good stiffness coefficient so that the working component 52 can deflect relative to the mounting component 30 in three-dimensional space. Illustrated, the flexural modulus of the elastic element 53 is greater than 47 MPa. This avoids the problem of the working component 52 vibrating and reducing the stability of the care operation due to the elastic element 53 being too soft, thereby achieving neat trimming of the edge grass, resulting in a smooth and aesthetically pleasing cut and improved trimming quality.

[0046] Combination Figure 1 , Figure 4 and Figure 5 As shown, in one possible implementation, when the lawn care mechanism 200 is in a non-operating state, the height difference between the two ends of the elastic member 53 is less than or equal to 2 cm. Understandably, when the working member 52 and at least part of the elastic member 53 extend outside the receiving space 301, the end of the elastic member 53 near the working member 52 will sag under the weight of the working member 52. Therefore, by setting the height difference between the two ends of the elastic member 53 within a suitable range, the smoothness and precision of the lawn edge trimming by the working member 52 are improved, resulting in a clean and aesthetically pleasing cut, improved trimming quality, and ensure that the working member 52 can perform lawn care work normally.

[0047] Combination Figure 1 , Figure 4 and Figure 5As shown, in one possible implementation, in the arrangement direction of the elastic element 53 and the working element 52, the area of ​​the outer contour of the radial cross-section of the elastic element 53 gradually decreases; or, the area of ​​the outer contour of the radial cross-section of the elastic element 53 gradually decreases from the middle to both ends; or, the area of ​​the outer contour of the radial cross-section of the elastic element 53 remains unchanged. Therefore, on the one hand, by setting the variable cross-section of the elastic element 53, the structural strength of the connection root of the elastic element 53 can be improved, avoiding the problem of the working element 52 being unstable due to its own weight; on the other hand, by setting the uniform cross-section of the elastic element 53, the processing difficulty of the elastic element 53 can be reduced, facilitating alignment and assembly.

[0048] Figure 6 This is a structural schematic diagram of the lawn care facility 200 provided in this application embodiment in its operational state, combined with... Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, in one possible implementation, the receiving portion 300 has a first opening 302A communicating with the external environment. The driving component 60 is used to drive the working piece 52 away from the receiving portion 300 through the first opening 302A. The driving component 60 is also used to retract the working piece 52 back into the receiving portion 300 through the first opening 302A. That is, at least a portion of the structure of the working piece 52 and the elastic member 53 can extend out of the receiving space 303 through the first opening 302A, allowing the working piece 52 to deflect relative to the mounting member 30 in three-dimensional space. Understandably, in the operating state, at least a portion of the working piece 52 can extend out of the mounting member 30 through the first opening 302A from the receiving space 303, so that the operating range of the working piece 52, i.e., the working area 501 of the working piece 52, is isolated from the wheels 110 of the mobile device 1000, thereby avoiding any impact on the motion control of the mobile device 1000. In non-operational state, the workpiece 52 can be retracted into the storage space 303 through the first opening 302A, thereby improving the mobility of the mobile device 1000 in complex terrain, preventing debris adhering to the free end of the workpiece 52 from entering the accommodating space 301, improving the safety and reliability of the workpiece 52 during operation, and facilitating cleaning.

[0049] Combination Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, in one possible implementation, the driving component 60, transmission component 70, working component 52, and first opening 302A are arranged sequentially along the width direction Y of the device body 100. The width direction Y is perpendicular to the plane formed by the traveling direction of the mobile device 1000 and the height direction Z of the device body 100, meaning the first opening 302A faces outward along the width direction Y. This allows the driving component 60 to directly drive the transmission component 70, causing the elastic component 53 and working component 52 to move linearly relative to the mounting component 30 in the extension direction of the mounting component 30. This results in a simple structure and improves the transmission efficiency and positioning accuracy of the lawn care mechanism 200. Secondly, by setting the working component 52 to extend laterally relative to the mounting component 30, the working component 52 can enter areas that the mobile device 1000 cannot cover, such as under bushes and on the sides of steps, improving the lawn care effect. Furthermore, the laterally extended working component 52 can better approach vertical obstacles such as walls, tree trunks, or fences, improving the edge trimming effect and avoiding problems such as missed mowing or collision damage.

[0050] Combination Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, in one possible implementation, the working area 501 of the working member 50 is tangent to or spaced from the second edge tangent 502 of the mounting member 30 near the working piece 52 in the extending direction of the mounting member 30. That is, when the working piece 52 moves away from the receiving portion 300 and operates, the working area 501 of the working piece 52 is tangent to or separate from the edge of the receiving portion 300. This reduces the risk of damage to the mounting housing 32 caused by the rotation of the working piece 52, and avoids the problem of insufficient rotational momentum of the cutting unit in the working area, which reduces the trimming quality. Specifically, the working area 501 of the working member 50 is tangent to or spaced from the side edge of the mounting base 31 near the working piece 52 in the extending direction of the mounting member 30.

[0051] Figure 7 This is a structural schematic diagram of a lawn care facility 200 in operation, provided in another embodiment of this application, in conjunction with... Figure 1 and Figure 7 As shown, in one possible implementation, the opening in the receiving section 300 includes a second opening 302B, which faces outward along the travel direction of the mobile device 1000, i.e., along the length direction X. The accommodating space 301 is located between opposite ends of the device body 100 in the width direction Y, and the storage space 303 is located at one end of opposite ends of the device body 100 in the width direction Y. The driving member 60 is used to drive the working piece 52 from one end of opposite ends of the device body 100 in the width direction Y, see... Figure 7 The driving component 60, shown by the dashed line, rotates through the second opening 302B to the other end of the opposite ends in the width direction Y of the device body 100. Figure 7 The solid line shows the drive component 60. Schematic, the working part 52 moves from the left side of the device body 100 to the front right side of the device body 100, and the transmission component 70 finally abuts against the edge of the second opening 302B of the mounting housing 32. The extension direction of the transmission component 70 forms an acute angle with the width direction Y. By setting the second opening 302B on the side of the receiving part 300 away from the device body 100 along the length direction X, the working part 52 can be moved efficiently and accurately to the working position with simple structural components, while avoiding collision damage to the working part 52 from obstacles on the side of the mobile device 1000, which helps to extend the service life of the lawn care mechanism 200.

[0052] Figure 8 This is a structural schematic diagram of a lawn care facility 200 in operation, provided in another embodiment of this application, in conjunction with... Figure 1 and Figure 8 As shown, in one possible implementation, the openings provided in the receiving portion 300 include a first opening 302A and a second opening 302B. The first opening 302A faces outward along the direction of travel perpendicular to the mobile device 1000, that is, the first opening 302A faces outward along the width direction Y of the device body 100. The second opening 302B faces outward along the direction of travel of the mobile device 1000, that is, the first opening 302A faces outward along the length direction X of the device body 100. The second opening 302B intersects with the first opening 302A. The driving member 60 is used to drive the transmission member 70 to pass sequentially through the second opening 302B and the first opening 302A, so that the working piece 52 moves from at least one end of the device body 100 along the direction of travel to the side of the device body 100. Schematic, the working piece 52 can move from one end of the device body 100 along the direction of travel, for example from the front end, to one side of the device body 100 along the width direction Y, for example, the right side. Compared to Figure 7 The lawn care facility shown is 200. Figure 8 The lawn care mechanism 200 shown can move the working part 52 to the working position efficiently and accurately with simple structural components, and further extend the working part 52 out of the main body 100 of the equipment, which helps to expand the effective working range of the lawn care mechanism 200.

[0053] Figure 9 This is a structural diagram of a lawn care facility in a non-operational state, provided in another embodiment of this application, in conjunction with... Figure 1 , Figure 2 and Figure 9As shown, in one possible embodiment, the receiving portion 300 is formed by the mounting base 31 at one end along its width direction Y, the mounting shell 32 on one side along its width direction Y, and the side of the mounting shell 32 away from the device body 100 along its length direction X. The first opening 302A is located only on one side of the mounting shell 32 along its width direction Y. That is... Figure 9 The shown housing 300 is a closed space with an opening on one side. This helps to further prevent the working part 52 from being disturbed by the outside and further improves the overall integrity of the product.

[0054] Combination Figure 1 and Figure 2 As shown, in one possible implementation, the mobile device 1000 further includes a cutting mechanism 90. The cutting mechanism 90 is mounted on the bottom of the device body 100. The cutting area 901 of the cutting mechanism 90 has a tangent line in the width direction Y of the mobile device 1000 near the workpiece 52 defined as a first edge tangent line 902, which is tangent to the working area 501 of the workpiece 52; or, the perpendicular distance between the first edge tangent line 902 and the working area 501 of the workpiece 52 is less than or equal to a preset distance D1; or, the first edge tangent line 902 is located within the working area 501 of the workpiece 52. Specifically, the cutting mechanism 90 is configured as the main cutting mechanism of the mobile device 1000. The lawn care mechanism 200 is configured as an auxiliary cutting mechanism of the mobile device 1000. The main cutting mechanism and the auxiliary cutting mechanism are used for mowing lawns. Therefore, the cutting mechanism 90 of the mobile device 1000 and the working piece 52 on the lawn care mechanism 200 can perform cutting operations simultaneously, and the movement stroke of the working piece 52 can be controlled so that the cutting area 901 of the cutting mechanism 90 is tangent or nearly tangent to the working area 501 of the working piece 52, thereby increasing the single-operation cutting width of the mobile device 1000 and improving the operating efficiency of the lawnmower. For example, in this embodiment, the preset distance D1 can be 2cm. In other embodiments, the preset distance D1 can also be, but is not limited to, 1cm, 3cm, 5cm, 7cm, 10cm, etc. The cutting area 901 and the working area 501 are respectively spaced apart from the traveling wheels 110 of the mobile device 1000 to avoid interference with the traveling wheels 110. It should be noted that the working area 501 of the working piece 52 refers to the maximum working area covered by the working piece 52 when the mobile device 1000 is in a preset position on the projection plane perpendicular to the height direction Z of the mobile device 1000. The cutting area 901 of the cutting mechanism 90 refers to the maximum working area covered by the cutting mechanism 90 when the mobile device 1000 is in a preset position on the projection plane of the height direction Z perpendicular to the mobile device 1000. The preset position can be any position in the lawn, and the working area 501 and the cutting area 901 are the working areas corresponding to the same position when the mobile device 1000 passes through the lawn.

[0055] Combination Figure 1 and Figure 2 As shown, in one possible implementation, the cutting height of the working piece 52 can be higher than the cutting height of the cutting mechanism 90. Understandably, the taller and denser the grass blades, the greater the load on the cutting mechanism 90. Therefore, when the mobile equipment 1000 performs lawn mowing, pre-cutting can be done by the working piece 52, and then secondary cutting can be performed by the cutting mechanism 90 on the area already cut by the working piece 52. This allows for finer grass clippings, facilitating natural lawn regeneration, reducing the load on the cutting mechanism 90, and extending the service life of the mobile equipment 1000. It should be noted that the control route of the main body 100 is adjusted based on the installation position of the working piece 52. For example, in this embodiment, the working piece 52 is located on the right side of the main body 100, and the mobile equipment 1000 cuts more from left to right. The mobile device 1000 can simultaneously activate the working piece 52 and the cutting mechanism 90 to perform grass mowing operations; alternatively, it can activate the working piece 52 first to perform grass mowing operations, and then activate the cutting mechanism 90 to perform grass mowing operations; or alternatively, it can activate the cutting mechanism 90 first to perform grass mowing operations, and then activate the working piece 52 to perform grass mowing operations. The operating mode of the working piece 52 and the cutting mechanism 90 can be set according to the actual situation, and this application embodiment does not impose specific limitations.

[0056] Combination Figure 1 and Figure 2 As shown, in one possible implementation, the cutting mechanism 90 can be configured as one or more. At least one cutting mechanism 90 is disposed at the bottom of the equipment body 100. The cutting mechanism 90 is detachably mounted on the equipment body 100. This facilitates, on the one hand, maintenance, replacement, and cleaning of the various parts of the cutting mechanism 90 without disassembling the entire equipment body 100, and allows for separate transport of the cutting mechanism 90 and the equipment body 100, improving transportation and installation convenience; on the other hand, it enables flexible switching between different cutting mechanisms 90. For example, the equipment body 100 can switch between different cutting mechanisms 90 according to different work tasks, improving the flexibility of the mobile device 1000's work switching and enriching the usage scenarios of the mobile device 1000. Of course, in some embodiments, the cutting mechanism 90 can also be non-detachably connected to the equipment body 1000; this application does not specifically limit this.

[0057] Combination Figure 1 and Figure 4As shown, in one possible implementation, the lawn care mechanism 200 further includes a deflection detection component 54 and a control circuit board. The deflection detection component 54 is used to detect the deflection angle of the working component 52 relative to the mounting component 30 in three-dimensional space. The control circuit board is used to control the working component 52 to stop working when the deflection angle is greater than or equal to a preset deflection angle. Thus, when the deflection amplitude of the working component 52 is detected to exceed the preset angle, the working component 52 stops working, improving the safety and reliability of the repair mechanism during repair operations. The control circuit board is used to provide power and transmit control signals to electrical components such as the working component 50, the drive component 60, and the deflection detection component 54.

[0058] Combination Figure 1 , Figure 3 and Figure 4 As shown, in one possible implementation, the elastic element 53 is provided with a wire hole 5301 in the extending direction of the mounting component 30. The lawn care mechanism 200 also includes a power connector 10 and a connecting cable. The power connector 10 is used to connect to the device body 100 of the mobile device 1000, one end of the connecting cable is used to connect to the power connector 10, and the other end of the connecting cable passes through the wire hole 5301 and connects to the working component 52. Thus, on the one hand, the wire hole 5301 provided by the elastic element 53 can provide a protective channel for the connecting cable, avoiding direct damage to the connecting cable from the rotation of the working component 52, grass clippings, or external collisions, thereby extending the service life of the power cable; on the other hand, the wire hole 5301 can limit the direction of the connecting cable, preventing the connecting cable from being accidentally pulled or caught in rotating components, thereby improving the reliability and safety of the operation of the working component 52.

[0059] Figure 10 This is a schematic diagram of the mating structure of the transmission component 70, the elastic element 53, and the working component 52 provided in the embodiments of this application. Figure 1 , Figure 2 , Figure 4 and Figure 10 As shown, in one possible implementation, the elastic element 53 is indirectly connected to the working part 52 and the transmission component 70. Specifically, the working part 52 includes a working head 521 and a connecting head 522, i.e., the lawn care mechanism 200 includes the working head 521, which can be used to repair lawns outside the travel path of the mobile device 1000. One end of the connecting head 522 is fixedly connected to the working head 521, and the other end of the connecting head 522 is fixed in the wire hole 5301. One end of the transmission component 70 is drively connected to the drive component 60, and the other end of the transmission component 70 is fixed in the wire hole 5301. This improves the reliability and stability of the connection between the elastic element 53, the transmission component 70, and the working part 52, and also improves space utilization, resulting in a simpler overall structure. Of course, in some embodiments, the elastic element 53 is directly connected to the working part 52 and the transmission component 70.

[0060] Combination Figure 1 , Figure 2 , Figure 4 and Figure 10 As shown, in one possible implementation, the working head 521 includes a rotating component 523 and a cutting component 524. The rotating component 523 is electrically connected to the equipment body 100. The cutting component 524 is disposed on the rotating component 523. The rotating component 523 drives the cutting component 524 to rotate to perform the mowing operation. The cutting component 524 can be configured as a cutting rope, which breaks grass blades and stems when rotating, thereby achieving mowing.

[0061] Combination Figure 1 , Figure 2 , Figure 4 and Figure 10 As shown, in one possible embodiment, the lawn care mechanism 200 further includes an electrical conduction component. The electrical conduction component is disposed on the mounting component 30 and the working member 52. When the working member 52 is in a first position, the electrical conduction component is used to disconnect the circuit between the working member 52 and the power supply connector 10; when the working member 52 is in a second position, the electrical conduction component is used to connect the circuit between the working member 52 and the power supply connector 10. Thus, the circuit connection and disconnection between the working member 52 and the power supply connector 10 can be achieved without additional tools, resulting in a simple structure.

[0062] Combination Figure 1 , Figure 2 , Figure 4 and Figure 10 As shown, in one possible implementation, the connector 522 includes a first connecting portion 5221 and a second connecting portion 5222 fixedly connected to the first connecting portion 5221. The first connecting portion 5221 is detachably connected to the working head 521. For example, in this embodiment, the first connecting portion 5221 and the working head 521 are detachably plugged together, thereby facilitating maintenance, replacement, and other operations of the working head 521. Of course, the first connecting portion 5221 and the working head 521 can also be fixedly connected non-detachably. For example, the first connecting portion 5221 and the working head 521 can be integrally formed. The second connecting portion 5222 is fixedly connected to the elastic member 53. The elastic member 53 has an internal thread in the wire hole 5301, that is, the inner sidewall of the elastic member 53 has an internal thread. The second connecting portion 5222 has an external thread that screws into the internal thread of the elastic member 53. Thus, a detachable connection between the elastic member 53 and the working member 52 is achieved. Of course, in another embodiment, one end of the connector 522 is fixedly connected to the working head 521, and the other end of the connector 522 is sleeved on the outer wall of the elastic member 53. For example, the outer wall of the elastic member 53 is provided with external threads, and the connector 522 is provided with internal threads that are screwed into the external threads of the elastic member 53. Thus, a detachable connection between the elastic member 53 and the working head 521 is achieved.

[0063] Combination Figure 1 , Figure 2 , Figure 4 and Figure 10 As shown, in one possible implementation, when the elastic element 53 is connected to the working element 52, a layer of adhesive is applied to both the working element 52 and the elastic element 53, thereby improving the stability and reliability of the connection between the elastic element 53 and the working element 52. The working element 52 and the elastic element 53 can also be connected together by both adhesive bonding and screwing. The second connecting portion 5222 can also be fixedly connected to the elastic element 53 by an interference fit. For example, the outer diameter of the second connecting portion 5222 is larger than the outer diameter of the elastic element 53, so that when the second connecting portion 5222 is inserted into the thread hole 5301 of the elastic element 53, the portion of the elastic element 53 in contact with the second connecting portion 5222 deforms and connects with the second connecting portion 5222, thus achieving a fixed connection between the elastic element 53 and the working element 52. In another possible implementation, the working element 52 and the transmission component 70 are each fixed to both ends of the elastic element 53 by a locking structure. The fixed connection method between the elastic element 53 and the working element 52 and the transmission component 70 can be set according to actual conditions, and this application embodiment does not impose specific limitations.
