Abstract
Description
Technical Field
[0001] This application relates to the field of robotics, and more particularly to a mobile device. Background Technology
[0002] With the popularization of intelligent mobile robot technology, lawnmowers with path planning capabilities are gradually replacing traditional artificial turf maintenance methods. However, in practical applications, lawnmowers have weak edge handling capabilities, especially for insurmountable boundaries. For example, when there are fixed obstacles such as building walls, wooden fences, or cliff edges at the lawn edge, the layout design of the cutting mechanism and wheels makes it difficult to achieve edge-hugging operation, leaving an uncut area between the lawnmower and the obstacle. Users need to frequently manually mow the edge areas, greatly diminishing the value of automation. Therefore, there is an urgent need for a lawnmower design that can effectively operate at edges. Utility Model Content
[0003] This application provides a mobile device in which the lawn care mechanism is located in front of the main body of the mobile device. The working area of the lawn care mechanism is in the left / right front of the main body of the mobile device, which allows the mobile device to perform operations in the edge area and avoids the problem of restricting the mobility of the mobile device by setting it on the side of the main body of the device externally.
[0004] Firstly, embodiments of this application propose a mobile device, comprising: a device body; and a lawn care mechanism disposed at at least one end of the device body along the travel direction of the mobile device and electrically connected to the device body. The projection of the working area of the lawn care mechanism onto the ground is a first projection area, and the projection of the device body onto the ground is a second projection area. When the lawn care mechanism is in operation, the first projection area simultaneously extends at least partially beyond the second projection area along both the travel direction and the width direction of the device body. Thus, on the one hand, the problem of the lawn care mechanism restricting the mobility of the mobile device by being externally mounted on the side of the device body is avoided; on the other hand, the lawn care mechanism is installed at the front and / or rear of the device body, facilitating maintenance, reducing the space occupied by the lawn care mechanism on the device body, and improving the overall compactness of the mobile device structure.
[0005] In one possible implementation, the lawn care mechanism includes a working component located at at least one of opposite ends of the main body of the device in the width direction. The working component is designed to be at least partially exposed in the second projection area simultaneously along the travel direction and the width direction during operation. In the working state, the working component can extend from the accommodating space through an opening to the mounting component, thereby performing work on the lawn. In the non-working state, the working component can retract into the accommodating space, thereby improving the mobility of the mobile device in complex terrain, preventing debris adhering to the free end of the working component from entering the storage space, improving the safety and reliability of the working component, and facilitating cleaning.
[0006] In one possible implementation, the lawn care mechanism includes a drive component and a transmission component. The drive component is electrically connected to the main body of the device. 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 out of the main body of the device along the width direction of the main body of the device. The drive component is also used to retract the working part back to the main body of the device. Therefore, on the one hand, the drive component drives the transmission component to move the working part linearly along the extension direction of the relative mounting component, which is simple in structure and improves the transmission efficiency and positioning accuracy of the lawn care mechanism; on the other hand, by setting the working part to extend laterally relative to the mounting component, the working part can enter areas that the mobile equipment cannot cover, such as under bushes and the sides of steps, which improves the lawn care effect. Moreover, the laterally extended working part can get closer to vertical obstacles such as walls, tree trunks or fences, which improves the edge trimming effect and avoids problems such as missed cutting or collision damage; furthermore, the drive component and transmission component are set in the accommodating space, which can prevent grass clippings and mud from entering and acting on the drive component and transmission component, improve the reliability of transmission and extend service life, and allow the working part to retract into or near the accommodating space when not in operation, which improves the mobility of the mobile equipment in complex terrain.
[0007] In one possible implementation, the number of the driving component, the transmission component, and the working parts are all at least two. At least two working parts are used to extend out of the main body of the device from opposite directions during operation, and at least two working parts are also used to retract into the main body of the device from opposite directions upon completion of the operation. On the one hand, the mobile device can simultaneously operate on the left front and right front edge areas using two working parts, thereby increasing the area of operation per cycle and improving work efficiency. On the other hand, each working part has an independent driving component and transmission component, allowing the mobile device to select the appropriate working part to operate on the left front or right front edge area according to actual conditions, improving the flexibility of the mobile device. It is understood that, along the height direction, the two working parts can be on the same plane or different planes to adapt to different operational needs.
[0008] In one possible implementation, the mobile device includes a cutting mechanism located at the bottom of the device body for cutting grass on the lawn to be mowed; a lawn care mechanism is used to cut grass at the edges of the lawn to be mowed; the cutting mechanism, the front end of the device body, and the lawn care mechanism are arranged sequentially along the direction of travel of the mobile device. Thus, the working parts on the cutting mechanism and the lawn care mechanism of the mobile device can perform cutting operations simultaneously, thereby increasing the single-operation cutting width of the mobile device and improving the operating efficiency of the lawnmower.
[0009] In one possible implementation, the working part includes a rotating component and a strip-shaped cutting component. The rotating component is electrically connected to the main body of the equipment, and the cutting component is rotatably connected to the rotating component. The working area formed by the rotation of the cutting component has a circular projection along the height direction of the main body of the equipment. A circular cutting area helps to form a continuous working area and avoids missed cuts.
[0010] In one possible implementation, the distance between the cutting element and the grass to be mowed is greater than or equal to the distance between the cutting mechanism and the grass to be mowed. Therefore, when the mobile equipment performs lawn mowing, the cutting element can first perform pre-cutting, and then the cutting mechanism can perform secondary cutting on the area already cut by the cutting element. This allows for finer grass clippings, facilitating natural lawn regeneration, reducing the load on the cutting mechanism, and extending the lifespan of the mobile equipment.
[0011] In one possible implementation, the cutting area of the cutting mechanism is tangential to or partially overlaps with the working area of the lawn care mechanism. Therefore, by tangentially or partially overlapping the cutting area of the cutting mechanism with the working area of the lawn care mechanism, the single-operation cutting width of the mobile device is increased, thereby improving the operational efficiency of the mobile device.
[0012] In one possible implementation, the distance between the cutting area of the cutting mechanism and the working area of the lawn care mechanism along the travel direction is less than or equal to two centimeters. By setting the distance between the working areas of the first cutting mechanism and the second cutting mechanism to be less than or equal to two centimeters, it is beneficial to increase the single-operation cutting width of the mobile device and improve the operating efficiency of the mobile device.
[0013] In one possible implementation, the mobile device includes wheels located at the bottom of the device body for driving the mobile device. The working area of the lawn care mechanism is separated from the wheels. The wheels are not aligned with the edge tangent, thus avoiding the risk of interference between the lawn care mechanism and the wheels, improving the safety of the lawn care mechanism, and ensuring the completion of supplementary work on the edge area.
[0014] In one possible implementation, the walking wheels include a first wheel and a second wheel, arranged sequentially along the travel direction of the mobile device. The projection of the line connecting the center of the working area of the lawn care mechanism to the rotation center of the adjacent first wheel onto the ground makes an angle α with the travel direction, where tanα is [√3 / 3, 4]. The working area can move along its width, which is beneficial for adapting to different scenarios and increasing the ability to perform supplementary work at the edges. Attached Figure Description

[0017] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation
[0018] For ease of understanding, the relevant technical terms involved in the embodiments of this application will be explained and described below.
[0019] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" means that the components are connected to each other and their relative positional relationship remains unchanged after connection. "Rotary connection" means that the components are connected to each other and can rotate relative to each other after connection. The term "integral molding" means that during the formation of one of a plurality of components, that component is connected to the other components without requiring further processing (such as bonding, welding, snap-fit connection, screw connection) to connect the two components together. The directional terms mentioned in the embodiments of this application, such as "top," "bottom," "inner," "outer," and "side," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to 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 the embodiments of this application. The term “and / or” as used in this application refers to any combination of one or more of the associated listed items, as well as all possible combinations, and includes such combinations.
[0020] The development of automated mobile devices is rapid, and their application scenarios are gradually increasing. Automated mobile devices, such as lawn care robots, can automatically perform tasks on lawns, such as mowing, watering, seeding, and fertilizing, making them essential robots for home outdoor lawn maintenance. However, current lawn care robots 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. While lawn care robots can address this issue by adding additional lawn management mechanisms, these mechanisms often fail to effectively cover the edges of the work area.
[0021] See Figure 1 , Figure 1 This is a schematic diagram of the structure of a mobile device 1000 provided in an embodiment of this application, which can be used for tasks such as mowing, watering, sowing, and fertilizing. The mobile device 1000 includes a main body 100 and a lawn care mechanism 200. The lawn care mechanism 200 is mounted on the main body 100. The main body 100 is used for primary tasks, while the lawn care mechanism 200 is used for supplementary tasks. Thus, the mobile device 1000 can care for the lawn through the lawn care mechanism 200, eliminating the need for users to manually manage the lawn edges, improving user experience, and reducing labor intensity.
[0022] See Figure 1 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 by being pushed by a user. Alternatively, the mobile device 1000 may have its own mobility. Specifically, the mobile device 1000 includes wheels, and the mobile device 1000 can move automatically on the ground via the wheels.
[0023] See Figure 1In this embodiment, the lawn care mechanism 200 is detachably mounted on the equipment body 100 and electrically connected to the equipment body 100. Illustratively, the lawn care mechanism 200 and the equipment body 100 can be electrically connected via conductive components, such as conductive cables and conductive connectors. 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 equipment body 100, and allows for separate transportation of the lawn care mechanism 200 and the equipment body 100, improving transportation and installation convenience; on the other hand, it enables flexible switching between different lawn care mechanisms 200. For example, the equipment body 100 can switch between different lawn care mechanisms 200 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 lawn care mechanism 200 may also be non-detachably connected to the equipment body 1000; this embodiment does not specifically limit this.
[0024] For the sake of accuracy, all references to direction in this article should be expressed in terms of direction. Figure 1 For 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 the embodiments of this application are relative positions and do not constitute a limitation on implementation. 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; this application does not impose specific limitations. For example, in this embodiment, the mounting component 30 is elongated. The extension direction F of the mounting component 30 is the length direction of the lawn care mechanism 200 and 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 accompanying drawings; this application does not impose specific limitations. Of course, in some embodiments, the extension direction F of the mounting component 30 can also be set at an angle to the width direction Y of the mobile device 1000; this application does not impose specific limitations on this embodiment.
[0025] See Figure 1 In this embodiment, the lawn care mechanism is disposed at at least one end of the main body 100 along the travel direction of the mobile device 1000. The two ends of the main body 100 along the travel direction of the mobile device 1000 can be the front end and the rear end, respectively. That is, the lawn care mechanism 200 can be located at the front end of the main body 100, the rear end of the main body 100, or both. It should be noted that the travel direction of the main body 100 is the length direction X. Therefore, on the one hand, this avoids the problem of the lawn care mechanism 200 being externally mounted on the side of the main body 100, which would restrict the passage of the mobile device 1000; on the other hand, installing the lawn care mechanism 200 at the front end and / or rear end of the main body 100 facilitates maintenance, reduces the space occupied by the lawn care mechanism 200 on the main 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 equipment body 100, so that the equipment body 100 has a forward impact function, which reduces the impact force on the equipment body 100 and extends its service life.
[0026] See Figure 2 , Figure 2 yes Figure 1 The diagram shows a top view of the mobile device 1000 in its working state. In this embodiment, the projection of the working area 501 of the lawn care mechanism 200 onto the ground is the first projection area A, and the projection of the main body 100 onto the ground is the second projection area B. It should be noted that the projection onto the ground is the same as the projection onto the XY plane shown in the diagram. For example, the working area 501 of the lawn care mechanism 200 refers to the maximum working area covered by the lawn care mechanism 200 when the mobile device 1000 is in a preset position on the projection plane of the height direction Z of the mobile device 1000. The preset position can be any location on the lawn. Therefore, the lawn care mechanism 200 can perform supplementary work on edge areas. The working area 501 is concentrated on the front or rear side along the length direction, which helps to improve the coverage of edge work by the mobile device 1000 and improve the overall working efficiency of the mobile device 1000.
[0027] Combination Figure 1 and Figure 2As shown, in this embodiment, the lawn care mechanism 200 is located at the front end of the equipment body 100 as an example. The lawn care mechanism 200 includes a mounting component 30 and a working component 50. The mounting component 30 is used to install on the equipment body 100 of the mobile device 1000. The working component 50 includes a working part 52 and an elastic part 53. One end of the elastic part 53 is fixedly disposed relative to the mounting component 30, and the other end of the elastic part 53 is connected to the working part 52. The working part 52 can be deflected relative to the mounting component 30 in three-dimensional space. The lawn care mechanism 200 provided in this application embodiment has several 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 mechanism, enhancing the safety and reliability of the working component 52. Understandably, when the elastic component 53 is configured as a corrugated pipe or elastomer, it prevents grass clippings from getting stuck on the elastic component 53, reducing the cleaning difficulty and service life of the elastic component 53.
[0028] Combination Figure 1 and Figure 2 As shown, in one possible implementation, the elastic element 53 is configured as a spring. The elastic element 53 is cylindrical in shape. When the mobile device 1000 moves along its length direction X, the working member 50 extends from the accommodating cavity 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.
[0029] It should be noted that, Figure 2The purpose is merely to schematically describe the arrangement between the mounting component 30 and the working component 50, and is not to specifically limit the connection positions, connection relationships, or specific structures of the various components. The working component 52 can be configured as, but is not limited to, a cutting mechanism, a spraying structure, a marking structure, a seeding structure, a cleaning structure, or a collection structure. Understandably, to enable those skilled in the art to better understand the working component 52, a cutting mechanism is used as an example for detailed description. It should be noted that the configuration of the working component 52 as a cutting mechanism is for illustrative purposes only, and the embodiments in this application do not impose specific limitations. For example, the product type of the working component 52 can also be set according to actual needs.
[0030] See Figure 2 In this embodiment, the working component 52 is located at at least one of the opposite ends of the width direction Y of the device body 100, that is, it can be the left end, the right end, or both ends. The working component 52 is used to simultaneously expose at least partially along the length direction X and along the width direction Y in the second projection area B during operation.
[0031] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, Figure 3 This is a schematic diagram of the lawn care facility 200 provided in this application embodiment in a non-operational state. Figure 4 yes Figure 3 The schematic diagram of the cross-sectional structure of the lawn care mechanism 200 shown illustrates that, in this embodiment, the mounting component 30 includes a mounting base 31 and a mounting shell 32. The mounting shell 32 is connected to the mounting base 31 to form an accommodating space 301 and an opening 302 that connects to the external environment. In the working state, the working component 52 can extend from the accommodating space 301 through the opening 302 to perform work on the lawn. In the non-working state, the working component 52 can retract into the accommodating space 301, thereby improving the mobility of the mobile device 1000 in complex terrain, preventing debris adhering to the free end of the working component 52 from entering the storage space 303, improving the safety and reliability of the working component 52, and facilitating cleaning.
[0032] Combination Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, Figure 5 yes Figure 3The exploded structural diagram of the lawn care mechanism 200 shown is illustrated in this embodiment. The lawn care mechanism 200 includes a drive component 60 and a transmission component 70. The drive component 60 and transmission component 70 are located within the accommodating space 301 of the mounting component 30. The drive component 60 is electrically connected to the device body 100, which supplies power to the drive component 60. One end of the drive component 60 is movably connected to the transmission component 70, and the other end of the transmission component 70 is connected to the working piece 52. The drive component 60 transmits power to the transmission component 70, thereby causing the transmission component 70 to drive the working piece 52 to move linearly along the extension direction F of the mounting component 30. Specifically, the drive component 60 drives the working piece 52 to extend out of the device body 100 along the extension direction F of the mounting component 30, enabling the working piece 50 to perform operations on edge areas. After the operation is completed, the drive component 60 also retracts the working piece 52 back to the mounting part 20, avoiding an abrupt structural change in the mobile device 1000. Therefore, on the one hand, the drive component 60 drives the transmission component 70 to move the working part 52 linearly along the extension direction F relative to the mounting component 30, which is simple in structure and improves the transmission efficiency and positioning accuracy of the lawn care mechanism 200; on the other hand, by setting the working part 52 to extend laterally relative to the mounting component 30, the working part 52 can enter areas that the mobile device 1000 cannot cover, such as under bushes and the side of steps, which improves the lawn care effect. Moreover, the laterally extended working part 52 can get closer to vertical obstacles such as walls, tree trunks or fences, which improves the edge trimming effect and avoids the problem of missed cutting or collision damage; furthermore, the drive component 60 and the transmission component 70 are set in the accommodating space 301, which can prevent grass clippings and mud from entering and acting on the drive component 60 and the transmission component 70, improve the reliability of transmission and extend service life, and allow the working part 52 to retract into or near the accommodating space 301 when not in operation, which improves the passability of the mobile device 1000 in complex terrain.
[0033] See Figure 2 In one possible implementation, the lawn care facility 200 may include a... Figure 2The lawn care mechanism 200 may include more or fewer components, combinations of certain components, or different components. For example, it may also include, but is not limited to, a communication mechanism, a lifting mechanism, and a reminder mechanism. The working component 50 of the lawn care mechanism 200 can establish a communication connection with external devices via the communication mechanism to receive care operation instructions and stop care operation instructions sent by the external devices. External devices can be, but are not limited to, smart devices such as mobile phones, tablets, computers, remote controls, and wearable devices. The lifting mechanism is used to drive the main body 100 of the equipment to perform lifting movements. The reminder mechanism can be configured as at least one of a speaker, warning light, vibrator, or display. The prompting mechanism is used to issue prompting information. The prompting information can be at least one of sound, text, light, vibration, or graphic content. The prompting information can be used to characterize the working status of the lawn care mechanism 200, reminding the user to intervene promptly when the lawn care mechanism 200 malfunctions, thereby improving the safety and reliability of the lawn care mechanism 200. The reminder mechanism can be installed on the lawn care mechanism 200; or, it can also be installed on the main body 100 of the equipment.
[0034] See Figure 6 , Figure 6 yes Figure 1 This is a cross-sectional schematic diagram of another embodiment of the lawn care mechanism 200 of the mobile device 1000. In this embodiment, the number of drive components 60, transmission components 70, and working parts 52 are all at least two. At least two working parts 52 are used to move in opposite directions to extend out of the main body 100 during operation, and at least two working parts 52 are also used to move in opposite directions back to the main body 100 after the operation is completed. In this embodiment, the number of drive components 60, transmission components 70, and working parts 52 are all two. On the one hand, the mobile device 1000 can simultaneously work on the left front and right front edge areas using two working parts 52, thereby increasing the area of a single operation and improving work efficiency. On the other hand, each working part 52 has an independent drive component 60 and transmission component 70, allowing the mobile device 1000 to select the appropriate working part 52 to work on the left front or right front edge area according to the actual situation, improving the flexibility of the mobile device 1000. It is understood that along the height direction Z, the two working parts 52 can be on the same plane or different planes to adapt to different operational needs. It is understandable that the drive component 60, transmission component 70, and working component 52 are arranged sequentially along the forward or reverse direction of the width Y. Alternatively, the drive component 60 may be located below the transmission component 70.
[0035] See Figure 7 , Figure 7 yes Figure 1The image shows a bottom view of the mobile device 1000. In this embodiment, the mobile device 1000 is used for lawn mowing operations. The mobile device 1000 includes a cutting mechanism 90, which is located at the bottom of the main body 100 and is used to cut grass on the lawn to be mowed. A lawn care mechanism 200 is used to cut grass on the edges of the lawn to be mowed. Along the length direction X, the cutting mechanism 90, the front end 101, and the lawn care mechanism 200 are arranged sequentially. That is, the cutting mechanism 90 is configured as the main cutting mechanism of the mobile device 1000. The lawn care mechanism 200 is configured as the auxiliary cutting mechanism of the mobile device 1000. The main cutting mechanism and the auxiliary cutting mechanism are used to perform lawn mowing operations. Thus, the working parts 50 provided on the cutting mechanism 90 and the lawn care mechanism 200 of the mobile device 1000 can perform cutting operations simultaneously, thereby increasing the single-operation cutting width of the mobile device 1000 and improving the operating efficiency of the lawn mower.
[0036] See Figure 7 In one possible implementation, the cutting mechanism 90 can be configured as one or more, and the cutting mechanism 90 is detachably mounted on the equipment body 100. This facilitates, on the one hand, the maintenance, replacement, and cleaning of the various parts of the cutting mechanism 90 without disassembling the entire equipment body 100, and allows for the 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.
[0037] Combination Figure 1 , Figure 2 , Figure 4 and Figure 8 As shown, Figure 8 This is a schematic diagram of the cooperative structure of the transmission component 70, the elastic element 53, and the working component 52 provided in this application embodiment. In one possible implementation, the elastic element 53 is indirectly connected to the working component 52 and the transmission component 70. Specifically, the working component 52 includes a cutting element 524 and a connector 522. One end of the connector 522 is fixedly connected to the cutting element 524, and the other end of the connector 522 is fixed in the thread hole 5301. One end of the transmission component 70 is connected to the driving component 60, and the other end of the transmission component 70 is fixed in the thread hole 5301. This improves the reliability and stability of the connection between the elastic element 53 and the transmission component 70 and the working component 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 component 52 and the transmission component 70.
[0038] Combination Figure 7 and Figure 8 As shown, in this embodiment, the working component 52 includes a rotating component 523 and a strip-shaped cutting component 524. The rotating component 523 is electrically connected to the main body 100, and the cutting component 524 is rotatably connected to the rotating component 523. The working area 501 formed by the rotation of the cutting component 524 has a circular projection along the height direction Z of the main body of the equipment. Specifically, the driving component 60 transmits power to the transmission component 70, which drives the rotating component 523 to drive the cutting component 524 to rotate to perform the mowing operation. The cutting component 524 can be configured as a cutting rope. When the cutting rope rotates, it can break the grass leaves and stems to achieve mowing. It is understood that the circular cutting area formed by the rotation of the cutting rope around the center helps to form a continuous working area and avoid missed cuts.
[0039] See Figure 7 In this embodiment, along the height direction Z, the distance between the cutting element 524 and the lawn to be mowed is greater than or equal to the distance between the cutting mechanism 90 and the lawn to be mowed. Understandably, the taller and denser the grass, the greater the load on the cutting mechanism 90. Therefore, when the mobile device 1000 performs lawn mowing, pre-cutting can be done first by the cutting element 524, and then secondary cutting can be performed by the cutting mechanism 90 on the area already cut by the cutting element 524. 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 device 1000. It should be noted that the control route of the main body 100 is adjusted based on the installation position of the cutting element 524. For example, in this embodiment, the cutting element 524 is located on the right side of the main body 100, and the mobile device 1000 cuts more from left to right. The mobile device 1000 can simultaneously activate the cutting element 524 and the cutting mechanism 90 to perform grass mowing operations; alternatively, it can activate the cutting element 524 first, and then activate the cutting mechanism 90; or it can activate the cutting mechanism 90 first, and then activate the cutting element 524. The operating mode of the cutting element 524 and the cutting mechanism 90 can be set according to actual conditions, and this application embodiment does not impose specific limitations. Therefore, the single-operation cutting width of the mobile device 1000 can be increased, improving the operating efficiency of the mobile device 1000.
[0040] See Figure 7In this embodiment, the cutting area 901 of the cutting mechanism 90 is tangent to or partially overlaps with the working area 501 of the lawn care mechanism 200. Specifically, the tangent line of the cutting area 901 of the cutting mechanism 90 near the cutting element 524 in the width direction Y of the mobile device 1000 is defined as the edge tangent line 902, which is tangent to the working area 501 of the lawn care mechanism 200; or, the edge tangent line 902 is located within the working area 501 of the working element 52. Thus, by making the cutting area 901 of the cutting mechanism 90 tangent to or partially overlap with the working area 501 of the lawn care mechanism 200, the single-operation cutting width of the mobile device 1000 is increased, thereby improving the operating efficiency of the mobile device 1000.
[0041] See Figure 7 In one possible implementation, the perpendicular distance between the edge tangent 902 and the working area 501 of the lawn care mechanism 200 is less than or equal to a preset distance D1. For example, in this embodiment, the preset distance D1 can be 2 cm. In other embodiments, the preset distance D1 can also be, but is not limited to, 1 cm, 3 cm, 5 cm, 7 cm, 10 cm, etc. By setting the distance between the cutting area 901 of the cutting mechanism 90 and the working area 501 of the lawn care mechanism 200 to be less than or equal to two centimeters, it is beneficial to increase the single-operation cutting width of the mobile device 1000 and improve the operating efficiency of the mobile device 1000.
[0042] See Figure 2 and Figure 7 In this embodiment, the mobile device 1000 includes wheels 110 located at the bottom of the main body 100, which drive the mobile device 1000 to move. The working area 501 of the lawn care mechanism 200 is separated from the wheels 110. Specifically, the wheels 110 are separated from the edge tangent 902, thereby avoiding the risk of interference between the lawn care mechanism 200 and the wheels 110, which helps to improve the safety of the lawn care mechanism 200 and ensures the completion of supplementary work on the edge area.
[0043] See Figure 7 In one possible implementation, the working area 501 is spaced apart from the traveling wheel 110 to avoid interference with the traveling wheel 110.
[0044] See Figure 7In this embodiment, the number of walking wheels 110 is set to four, namely two first wheels 1101 and two second wheels 1102. The 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. The other 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. The angle between the projection of the line connecting the center of the working area 501 of the lawn care mechanism 200 to the rotation center of the adjacent first wheel 1101 on the ground and the forward direction X is α, where tanα ranges from [√3 / 3, 4]. This means that the working area 501 can move along the width direction Y, which is beneficial for adapting to different scenarios and increasing the ability to perform supplementary work at the edges. The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
