Description

Technical Field

[0001] This application relates to the field of cutting equipment technology, specifically to a working mechanism and a walking device. Background Technology

[0002] With the development of technology, lawnmowers and sweepers are now commonly used to reduce the workload of users when caring for courtyards or maintaining gardens. For example, lawnmowers are used to cut lawns, and sweepers are used to clean courtyards.

[0003] Currently, to meet safety regulations, the working edges of working devices are typically concealed within the outer contour of the device to prevent collisions and injuries to users. However, this design limits the working range of the device. In areas near wall edges, the device's outer contour interferes with the wall, preventing the working parts from completing their tasks in that area. Summary of the Invention

[0004] In view of the above, it is necessary to provide a working mechanism and a walking device to reduce safety risks and increase the working range.

[0005] In a first aspect, embodiments of this application provide a working mechanism, including: a rotation drive; a connecting disk connected to the rotation drive; a working component including a first working component and a second working component, one end of the first working component being rotatably connected to the periphery of the connecting disk, and the other end of the first working component being movable to a first position or a second position to place the first working component in a folded state or an unfolded state, the second working component being rotatably connected to the other end of the first working component; and a limiting component disposed on the connecting disk and corresponding to the first working component, the limiting component being used to lock and connect with the first working component to restrict the first working component to the folded state; wherein, the first position is close to the connecting disk, and the second position is far from the connecting disk.

[0006] In some embodiments, the limiting component includes a first elastic member and a locking member. The locking member is slidably disposed on the connecting plate and can slide toward the first position. The first elastic member is connected to the locking member and the connecting plate respectively. The first elastic member is used to drive the locking member to slide toward the first position so that the locking member abuts against and limits the first working piece.

[0007] In some embodiments, the connecting plate has a sliding groove that extends toward the first position, the locking member is slidably disposed in the sliding groove, and the first elastic member is disposed in the sliding groove and located on the side of the locking member away from the first working member.

[0008] In some embodiments, the end of the first working member away from the connecting plate has a protrusion corresponding to the locking member, the protrusion being used to cooperate with the locking member to restrict the first working member to the folded state.

[0009] In some embodiments, the locking member has a pressing slope at one end facing the first working member, and the pressing slope is inclined toward the first position.

[0010] In some embodiments, a storage groove is provided on the peripheral sidewall of the connecting disc at a position corresponding to the first working component, and the storage groove is used to store the first working component when the first working component is in the folded state.

[0011] In some embodiments, the first working component has an arc-shaped surface on the side opposite to the connecting disk, and when the first working component is in the folded state, the arc-shaped surface is flush with the peripheral sidewall of the connecting disk.

[0012] In some embodiments, the working mechanism further includes a second elastic element, which is connected to the first working component and the connecting plate respectively. The second elastic element is used to drive the first working component to swing toward the connecting plate so that the first working component is in the folded state.

[0013] In some embodiments, the working components and the limiting components are multiple sets, each corresponding to the other, and the multiple sets of working components and the multiple sets of limiting components are evenly arranged with the axis of the connecting disc as the center.

[0014] In some embodiments, the rotation drive can drive the connecting disk to rotate along a first direction or a second direction; when the rotation drive drives the connecting disk to rotate along the first direction, the limiting component is locked to the first working piece; when the rotation drive drives the connecting disk to rotate along the second direction, the limiting component releases the restriction on the first working piece; wherein the first direction and the second direction are opposite.

[0015] In some embodiments, the first working element and / or the second working element is a cutting blade.

[0016] In some embodiments, the rotation drive includes a housing; the working mechanism further includes a protective component, the protective component including a support base, a swing arm module and a safety component, the support base being connected to the housing, the two ends of the swing arm module being rotatably connected to the support base and the safety component respectively, the swing arm module being able to drive the safety component to move to a third position and a fourth position, wherein the third position is located outside the rotation trajectory of the second working component when the first working component is in the folded state, and the projection of the fourth position on the working surface is located within the projection of the rotation trajectory of the second working component when the first working component is in the folded state on the working surface.

[0017] In some embodiments, the swing arm module includes a first swing arm and a second swing arm that are parallel to each other. The two ends of the first swing arm are rotatably connected to the support base and the safety component, respectively. The two ends of the second swing arm are rotatably connected to the support base and the safety component, respectively. The rotation axis of the end of the first swing arm near the safety component is parallel to the rotation axis of the end of the second swing arm near the safety component.

[0018] In some embodiments, the swing arm module further includes a swing drive, which is disposed on the support base and connected to the swing arm module.

[0019] The operating mechanism of this application embodiment includes a rotating drive component, a connecting plate, operating components, and a limiting component. When the operating mechanism is operating normally in an open area, the end of the first operating component near the limiting component moves to a first position, and the limiting component locks the first operating component into a folded state. At this time, the rotation radius of the second operating component is small, thereby avoiding collision with the user and reducing safety risks. When the operating mechanism is operating in an area near the edge of a wall, the limiting component releases the restriction on the first operating component, and the end of the first operating component near the limiting component moves to a second position, where the first operating component is in an unfolded state. At this time, the rotation radius of the second operating component increases, and the second operating component can effectively operate in the area near the edge of the wall, thereby increasing the operating range.

[0020] Secondly, embodiments of this application also provide a walking device, including the working mechanism described in the above embodiments.

[0021] The walking device in this application embodiment, by setting up a working mechanism, not only reduces safety risks but also facilitates work in areas near the edge of the wall, thereby increasing the working range of the walking device.

[0022] In some embodiments, the walking device further includes a housing and a walking assembly, the walking assembly being disposed at the bottom of the housing, and the rotation drive being disposed inside the housing; when the first working component is in the folded state, the rotation trajectory of the second working component is located within the outer contour of the housing; when the first working component is in the unfolded state, the rotation trajectory of the second working component protrudes beyond the outer contour of the housing and the walking assembly.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, it should be noted that "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that allows communication between the two components; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0033] Please see Figure 1 and Figure 5 This application provides a working mechanism 100, which is applied to a walking device 1000. The walking device 1000 can be a lawnmower, a sweeper, etc., and the working mechanism 100 is used to perform lawn mowing, sweeping, etc. For ease of understanding, this application uses a lawnmower as the walking device 1000 and the working mechanism 100 as the lawn mowing device as an example for illustration. Obviously, this is not a limitation of the embodiment of this application.

[0034] Please see Figure 1 and Figure 2 In this embodiment of the application, the working mechanism 100 includes a rotation drive 10, a connecting plate 20, a working component 30, and a limiting component 40.

[0035] Rotary drive component 10 is disposed in the housing 200 of the walking device 1000 (e.g., Figure 5As shown, the connecting disk 20 is connected to the rotation drive component 10. The working assembly 30 includes a first working component 31 and a second working component 32. One end of the first working component 31 is rotatably connected to the periphery of the connecting disk 20, and the other end of the first working component 31 can be moved to a first position or a second position so that the first working component 31 is in a folded state or an unfolded state. The second working component 32 is rotatably connected to the other end of the first working component 31. The first position is close to the connecting disk 20, and the second position is away from the connecting disk 20.

[0036] The limiting component 40 is disposed on the connecting plate 20 and corresponds to the first working piece 31. The limiting component 40 is used to lock the first working piece 31 to restrict the first working piece 31 to a folded state.

[0037] When the operating mechanism 100 is operating normally in an open area, the other end of the first operating component 31 moves to the first position, and the limiting component 40 is locked to the first operating component 31, restricting the first operating component 31 to a folded state. At this time, the rotation trajectory of the second operating component 32 is within the outer contour of the outer shell 200, thereby avoiding collision with the user and causing injury, thus reducing safety risks. When the operating mechanism 100 is operating in an area near the edge of a wall, the limiting component 40 releases the restriction on the first operating component 31, and the other end of the first operating component 31 moves to the second position, and the first operating component 31 is in an unfolded state. At this time, the rotation trajectory of the second operating component 32 protrudes outside the outer contour of the outer shell 200, and the second operating component 32 can effectively operate in the area near the edge of the wall, thereby increasing the operating range.

[0038] In some embodiments, the rotation drive 10 is a motor. In other embodiments, the rotation drive 10 may also be a pneumatic motor, a rotary cylinder, etc., and this application does not specifically limit it in this way.

[0039] In some embodiments, the second working element 32 is a cutting blade, which facilitates rapid cutting of the lawn.

[0040] In some other embodiments, the first working component 31 can also be a cutting blade. In this way, when the first working component 31 is in the unfolded state, both the first working component 31 and the second working component 32 can cut the lawn, thereby improving the cutting efficiency of the working mechanism 100.

[0041] In some other embodiments, the first working component 31 can be a cutting blade, and the second working component 32 can be a straw rope. This helps to reduce the operational risk of the working mechanism 100 and also reduces the risk of the second working component 32 scratching the wall.

[0042] In other embodiments, when the working mechanism 100 is used to perform cleaning operations, the second working component 32 may also be a cloth strip or a brush. When the working mechanism 100 is working in the area near the edge of the wall, the second working component 32 performs deep cleaning of the area near the edge of the wall, and this application embodiment does not specifically limit this.

[0043] In some embodiments, the rotation drive 10 can drive the connecting disk 20 to rotate along a first direction F1 or a second direction F2. When the rotation drive 10 drives the connecting disk 20 to rotate along the first direction F1, the limiting component 40 is locked to the first working component 31. When the rotation drive 10 drives the connecting disk 20 to rotate along the second direction F2, the limiting component 40 releases the restriction on the first working component 31. The first direction F1 and the second direction F2 are opposite.

[0044] When the operating mechanism 100 is operating normally in an open area, the rotating drive 10 drives the connecting plate 20 to rotate along the first direction F1. The limiting component 40 is locked to the first operating component 31, restricting the first operating component 31 to a folded state. The cutting radius of the second operating component 32 is small, and the rotation trajectory of the second operating component 32 cannot protrude beyond the outer contour of the outer shell 200, thus avoiding collision with the user and causing injury. When the operating mechanism 100 is operating in an area near the edge of a wall, the rotating drive 10 drives the connecting plate 20 to rotate along the second direction F2. The limiting component 40 releases the restriction on the first operating component 31, and the first operating component 31 is adjusted to an unfolded state. The cutting radius of the second operating component 32 becomes larger, and the rotation trajectory of the second operating component 32 protrudes beyond the outer contour of the outer shell 200. The second operating component 32 can effectively operate in the area near the edge of the wall. Since the locking and unlocking of the first working component 31 by the limiting component 40 is directly related to the direction of rotation of the drive connecting plate 20 by the rotation drive component 10, no manual control is required, thereby improving the convenience of using the working mechanism 100 and further reducing safety risks. In addition, by controlling the rotation drive component 10 to rotate along the first direction F1 or the second direction F2 to adjust the first working component 31 to a folded or unfolded state, no new drive structure or transmission structure is required, which helps to reduce costs.

[0045] In some embodiments, the first direction F1 is counterclockwise and the second direction F2 is clockwise. In other embodiments, by swapping the positions of the working component 30 and the limiting component 40, the first direction F1 can also be clockwise, and correspondingly, the second direction F2 can be counterclockwise. This application does not specifically limit this aspect.

[0046] Please refer to the following: Figure 3 and Figure 4In some embodiments, the limiting component 40 includes a locking member 41 and a first elastic member 42. The locking member 41 is slidably disposed on the connecting plate 20 and can slide toward a first position. The first elastic member 42 is connected to the locking member 41 and the connecting plate 20 respectively. The first elastic member 42 is used to drive the locking member 41 to slide toward the first position so that the locking member 41 abuts against the limiting first working member 31.

[0047] When the rotating drive 10 drives the connecting disc 20 to rotate along the first direction F1, the first elastic element 42 causes the locking element 41 to slide towards the first position. The locking element 41 abuts against the limiting first working element 31, thereby restricting the first working element 31 to a folded state. When the rotating drive 10 drives the connecting disc 20 to rotate along the second direction F2, during the period from stopping to rotating to the rated speed, the locking element 41, due to inertia, will overcome the force of the first elastic element 42 and slide in the opposite direction. The locking element 41 releases the restriction on the first working element 31, and the first working element 31 is adjusted to an unfolded state. Thus, by setting the limiting component 40 to include the first elastic element 42 and the locking element 41, the convenience of locking and unlocking the first working element 31 is improved.

[0048] In some embodiments, the first elastic element 42 may be a compression spring, a sheet, or the like.

[0049] In some embodiments, the connecting plate 20 is provided with a sliding groove 21, the sliding groove 21 extends toward a first position, the locking member 41 is slidably disposed in the sliding groove 21, and the first elastic member 42 is disposed in the sliding groove 21 and located on the side of the locking member 41 away from the first working member 31.

[0050] By setting the slide groove 21, the accuracy of the locking element 41 sliding on the connecting plate 20 is improved, thereby improving the convenience of locking and unlocking the first working piece 31. By setting the first elastic element 42 in the slide groove 21 and located on the side of the locking element 41 opposite to the first working piece 31, when the rotation drive 10 drives the connecting plate 20 to rotate in the second direction F2, it is convenient for the locking element 41 to slide in the opposite direction under the action of inertia and compress the first elastic element 42, thereby improving the accuracy of the locking element 41 in releasing the restriction on the first working piece 31.

[0051] In some embodiments, the end of the first working member 31 away from the connecting plate 20 has a protrusion 311 corresponding to the locking member 41. The protrusion 311 is used to cooperate with the locking member 41 to restrict the first working member 31 to a folded state.

[0052] Since the locking element 41 protrudes from the surface of the connecting plate 20, the protrusion 311 facilitates the accurate restriction of the first working piece 31 into a folded state by cooperating with the locking element 41.

[0053] In some embodiments, the locking member 41 has a pressing slope 411 at one end facing the first working member 31, and the pressing slope 411 is inclined toward the first position.

[0054] By setting the compression ramp 411, the protrusion 311 can push the compression ramp 411 to make the locking member 41 retract and compress the first elastic member 42, thereby improving the accuracy and convenience of adjusting the first working member 31 to the folded state.

[0055] In other embodiments, the limiting component 40 may also include a power component (not shown), a limiting component (not shown), and a sensor (not shown). The power component can be a telescopic cylinder, an electric push rod, etc., and is located on the connecting plate 20. The limiting component is connected to the power component, and the power component can drive the limiting component to move closer to or away from the first position. The sensor is electrically connected to the power component, and the sensor senses that the rotation drive 10 drives the connecting plate 20 to rotate along the first direction F1 or along the second direction F2. When the sensor senses that the rotation drive 10 drives the connecting plate 20 to rotate along the first direction F1, the power component drives the limiting component to move closer to the first position, and the limiting component abuts against and limits the first working member 31; when the sensor senses that the rotation drive 10 drives the connecting plate 20 to rotate along the second direction F2, the power component drives the limiting component away from the first position, and the limiting component releases its restriction on the first working member 31. The embodiments of this application do not specifically limit the structure of the limiting component 40.

[0056] Please refer to it again. Figure 2 In some embodiments, a storage groove 22 is provided on the peripheral sidewall of the connecting plate 20 at a position corresponding to the first working component 31. The storage groove 22 is used to store the first working component 31 when it is in a folded state.

[0057] By providing a storage slot 22 to store the first working piece 31 when it is in a folded state, the stability of the first working piece 31 in this state is improved, and the size of the first working piece 31 protruding from the connecting plate 20 when folded is reduced, thereby reducing the impact of the first working piece 31 on the cutting operation of the second working piece 32. Furthermore, this design also helps to reduce the size of the working mechanism 100 when the first working piece 31 is in a folded state.

[0058] In some embodiments, the first working component 31 has an arcuate surface 312 on the side opposite to the connecting disk 20. When the first working component 31 is in a folded state, the arcuate surface 312 is flush with the peripheral sidewall of the connecting disk 20.

[0059] With this configuration, when the first working component 31 is in a folded state, the outer contour of the structure formed by the first working component 31 and the connecting disc 20 is smoother, thereby reducing the probability of grass getting stuck; in addition, the first working component 31 will not affect the cutting operation of the second working component 32, thereby improving the cutting efficiency of the working mechanism 100.

[0060] Please refer to it again. Figure 4 In some embodiments, the working mechanism 100 further includes a second elastic element 60, which is connected to the first working element 31 and the connecting plate 20 respectively. The second elastic element 60 is used to drive the first working element 31 to swing toward the connecting plate 20 so that the first working element 31 is in a folded state.

[0061] By incorporating the second elastic element 60, when the working mechanism 100 moves from the edge of the wall to an open area, the rotating drive 10 first stops the rotation of the connecting plate 20. The second elastic element 60 then causes the first working component 31 to swing towards the connecting plate 20. The protrusion 311 overcomes the force exerted by the first elastic element 42 on the locking element 41, pushing the locking element 41 open and returning it to the locked position. The first working component 31 is then restricted to a folded state again. This improves the accuracy and convenience of adjusting the first working component 31 to a folded state.

[0062] In some embodiments, the second elastic element 60 is a torsion spring. In other embodiments, the second elastic element 60 may also be a tension spring, and this application does not specifically limit this.

[0063] Please refer to it again. Figure 1 , Figure 2 and Figure 3 In some embodiments, there are multiple sets of working components 30 and limiting components 40, each corresponding to the other. The multiple sets of working components 30 and the multiple sets of limiting components 40 are evenly arranged with the axis of the connecting disk 20 as the center.

[0064] By setting multiple sets of working components 30 and multiple sets of limiting components 40, when the working mechanism 100 is working in an open area or at the edge of a wall, the second working piece 32 of multiple working components 30 can perform cutting operations simultaneously, thereby improving the cutting efficiency of the working mechanism 100.

[0065] In some embodiments, when there are multiple sets of operating components 30 and limiting components 40, there are also multiple sets of storage slots 22 and multiple sets of second elastic elements 60, with each set of operating components 30, multiple storage slots 22 and multiple sets of second elastic elements 60 corresponding to one another.

[0066] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4In some embodiments, the rotation drive 10 includes a housing 11 and an output shaft 12 disposed on the housing 11. The output shaft 12 is connected to the connecting disk 20, and the output shaft 12 drives the connecting disk 20 to rotate. The working mechanism 100 also includes a protection component 50, which includes a support base 51, a safety component 52, and a swing arm module 53. The support base 51 is connected to the housing 11, and both ends of the swing arm module 53 are rotatably connected to the support base 51 and the safety component 52, respectively. The swing arm module 53 can drive the safety component 52 to move to a third position and a fourth position. The third position is located outside the rotation trajectory of the second working component 32 when the first working component 31 is in a folded state, and the projection of the fourth position on the working surface is located within the projection of the rotation trajectory of the second working component 32 when the first working component 31 is in a folded state on the working surface. Understandably, the working surface can be the ground, lawn, etc.

[0067] When the first working component 31 is in the folded state, the swing arm module 53 moves the safety component 52 to the third position. Since the third position is located outside the rotation trajectory of the second working component 32 when the first working component 31 is in the folded state, the safety component 52 can prevent the user from accidentally contacting the second working component 32, thereby reducing safety risks. When the first working component 31 is adjusted from the folded state to the unfolded state, the swing arm module 53 moves the safety component 52 to the fourth position. Since the projection of the fourth position on the working surface is within the projection of the rotation trajectory of the second working component 32 when the first working component 31 is in the folded state, the safety component 52 is retracted, which will not affect the normal unfolding of the first working component 31, nor will it affect the normal operation of the second working component 32 in the area near the wall edge.

[0068] In some embodiments, since the first working component 31 can be adjusted to a folded state or an unfolded state, and when the first working component 31 is in the folded state, the rotation trajectory of the second working component 32 is located within the outer contour of the housing 200, and when the first working component 31 is in the unfolded state, the rotation trajectory of the second working component 32 protrudes outside the outer contour of the housing 200, the working mechanism 100 can be set further away from the outer contour of the housing 200, and the safety component 52 can also be designed closer to the interior of the housing 200, which is beneficial to reducing the overall maximum width of the walking device 1000, and thus beneficial to reducing the size of the walking device 1000.

[0069] In some embodiments, the swing arm module 53 includes a first swing arm 531 and a second swing arm 532 that are parallel to each other. The two ends of the first swing arm 531 are rotatably connected to the support base 51 and the safety component 52, respectively. The two ends of the second swing arm 532 are rotatably connected to the support base 51 and the safety component 52, respectively. The rotation axis of the end of the first swing arm 531 near the safety component 52 is parallel to the rotation axis of the end of the second swing arm 532 near the safety component 52.

[0070] With this configuration, when the swing arm module 53 moves the safety component 52 from the third position to the fourth position, the swing arm module 53 can move the safety component 52 along a specific trajectory, ensuring that the safety component 52, without exceeding the maximum outline of the outer shell 200, first avoids the second working component 32 and rises rapidly, then quickly retracts towards the center after passing the second working component 32. Similarly, when the swing arm module 53 moves the safety component 52 from the fourth position to the third position, the swing arm module 53 can also move the safety component 52 along a specific trajectory, ensuring that the safety component 52 descends rapidly before approaching the second working component 32 and quickly avoids the second working component 32 when it approaches it. This improves the accuracy and efficiency of the swing arm module 53 in moving the safety component 52 to the third and fourth positions.

[0071] In some embodiments, the swing arm module 53 further includes a swing drive 54, which is disposed on the support base 51 and connected to the swing arm module 53.

[0072] The swing drive component 54 is configured to automatically move the safety component 52 to the third and fourth positions via the swing arm module 53, thereby improving the efficiency and accuracy of the swing arm module 53 in moving the safety component 52 to the third and fourth positions.

[0073] In some embodiments, the swing drive 54 may be a motor, a rotary cylinder, etc., and this application embodiment does not specifically limit it.

[0074] In some embodiments, the swing drive 54 is connected to the first swing arm 531. In other embodiments, the swing drive 54 may also be connected to the second swing arm 532, which is not specifically limited in this application.

[0075] In some embodiments, both the swing drive 54 and the rotation drive 10 are electrically connected to the controller (not shown) of the walking device 1000. When the rotation drive 10 drives the connecting plate 20 to rotate along the first direction F1, the swing drive 54, under the control of the controller, drives the safety component 52 to move to the third position via the swing arm module 53; when the rotation drive 10 drives the connecting plate 20 to rotate along the second direction F2, the swing drive 54, under the control of the controller, drives the safety component 52 to move to the fourth position via the swing arm module 53, thereby improving the accuracy of the safety component 52 in shielding and avoiding the second working component 32.

[0076] In summary, the operating mechanism 100 of this application embodiment is equipped with a rotation drive 10, a connecting plate 20, an operating component 30, and a limiting component 40. When the operating mechanism 100 is operating normally in an open area, the end of the first operating component 31 near the limiting component 40 moves to a first position, and the limiting component 40 is locked to the first operating component 31, restricting the first operating component 31 to a folded state. At this time, the rotation radius of the second operating component 32 is small, thereby avoiding collision with the user and causing injury, thus reducing safety risks. When the operating mechanism 100 is operating in an area near the edge of a wall, the limiting component 40 releases the restriction on the first operating component 31, and the end of the first operating component 31 near the limiting component 40 moves to a second position, where the first operating component 31 is in an unfolded state. At this time, the rotation radius of the second operating component 32 increases, and the second operating component 32 can effectively operate in the area near the edge of the wall, thereby increasing the operating range. In addition, the working mechanism 100 of this application embodiment adjusts the first working piece 31 to a folded state or an unfolded state by controlling the rotation drive 10 to rotate along the first direction F1 or the second direction F2, which improves the convenience of using the working mechanism 100 and reduces the cost.

[0077] Please refer to the following: Figure 5 This application also provides a walking device 1000, including the working mechanism 100 as described in the above embodiments.

[0078] The walking device 1000 of this application embodiment, by setting up the working mechanism 100, not only reduces safety risks, but also facilitates operations in areas near the edge of the wall, thereby increasing the working range of the walking device 1000.

[0079] In some embodiments, the walking device further includes a housing 200 and a walking assembly 300, the walking assembly 300 being disposed at the bottom of the housing 200, and the rotation drive 10 being disposed within the housing 200. When the first working member 31 is in a folded state, the rotation trajectory of the second working member 32 is located within the outer contour of the housing 200. When the first working member 31 is in an unfolded state, the rotation trajectory of the second working member 32 protrudes beyond the outer contours of the housing 200 and the walking assembly 300.

[0080] By configuring the rotation trajectory of the second working component 32 within the outer contour of the outer shell 200 when the first working component 31 is folded, and protruding from the outer contour of the outer shell 200 and the walking assembly 300 when the first working component 31 is unfolded, not only are safety risks reduced, but it also facilitates operation in areas near the wall edge, thus increasing the working range of the walking device 1000. Furthermore, the rotating drive component 10 is the core component of the working mechanism 100, containing numerous electronic components (not shown). Typically, it requires additional waterproof flexible components (not shown) or other waterproof structures for protection. By placing the rotating drive component 10 inside the outer shell 200, no additional waterproof structure is needed, effectively preventing rainwater or moisture from entering the rotating drive component 10 and causing short circuit damage. This improves the service life of the walking device 1000 and reduces costs. Moreover, this configuration reduces the likelihood of the working mechanism 100 failing due to grass clippings jamming it, thereby improving the stability of the walking device 1000 in performing tasks such as mowing.

[0081] It should be noted that, in order to improve the cutting effect at the edge of the lawn or near the edge of obstacles, related technologies can also employ a drive mechanism such as a motor, lead screw, or cylinder to actively drive the cutting component to move outwards from the main body of the lawnmower to reduce cutting dead angles (this embodiment is not illustrated). However, by actively driving the cutting component outwards from the main body of the lawnmower, the core components of the lawnmower may be damaged due to the movement of the cutting component. For example, the cutting component may accidentally collide with an obstacle and be damaged, or a drive mechanism malfunction may prevent the cutting component from resetting. It may also cause waterproofing problems for the main body of the lawnmower, thereby affecting its service life. This application addresses this issue by providing a rotating drive component 10, a connecting plate 20, a working component 30, and a limiting component 40. When the working mechanism 100 is operating normally in an open area, the end of the first working component 31 near the limiting component 40 moves to the first position, and the limiting component 40 is locked to the first working component 31, restricting the first working component 31 to a folded state. At this time, the rotation radius of the second working component 32 is small, thus avoiding collision with the user and causing injury, thereby reducing safety risks. When the working mechanism 100 is operating in an area near the edge of a wall, the limiting component 40 releases the restriction on the first working component 31, and the end of the first working component 31 near the limiting component 40 moves to the second position, where the first working component 31 is in an unfolded state. At this time, the rotation radius of the second working component 32 increases, and the second working component 32 can effectively operate in the area near the edge of the wall, thereby increasing the working range and reducing cutting dead angles.

[0082] In some embodiments, the walking assembly 300 is a wheel. In other embodiments, the walking assembly 300 may also be a tracked chassis, which is not specifically limited in this application.
