Description

Technical Field

[0001] This application relates to the field of lawnmower technology, and more specifically, to a lawnmower. Background Technology

[0002] The cutting components of a lawnmower are typically spaced apart from the machine body to prevent direct contact between the user and the high-speed rotating components, thus improving safety when operating the lawnmower in open areas. However, this distance also makes it difficult for the lawnmower to cut grass at the edges of lawns or near walls, requiring subsequent manual cleaning. Summary of the Invention

[0003] In view of this, this application provides a lawnmower to solve the technical problem that lawnmowers, in order to meet safety requirements, result in low lawn coverage at the edges of lawns or near walls.

[0004] One embodiment of this application provides a lawnmower. The lawnmower includes a main body, a cutting mechanism, and a protective mechanism. The cutting mechanism includes a cutting assembly. The cutting assembly is located below the main body and configured to cut grass on a working surface. The protective mechanism includes a first protective member and a transmission assembly. The transmission assembly is connected to the main body. The transmission assembly is connected to the first protective member. The transmission assembly is used to drive the first protective member to move relative to the main body. The first protective member has at least a first position and a second position. When the first protective member is in the first position, at least a portion of the horizontal projection of the first protective member is outside the horizontal projection of the main body, providing lateral protection to the horizontal height of the cutting assembly. When the first protective member is in the second position, in the horizontal direction, the first protective member is closer to the main body than when it is in the first position.

[0005] When the first protective element is in the first position, it effectively isolates the cutting component from the user or external environment, reducing the risk of injury from accidental contact with the cutting component during mowing. It also effectively prevents obstacles from contacting the cutting component and damaging it. This is suitable for lawnmowers operating in open areas or in work areas where users or pets may be nearby, ensuring the lawnmower meets safety standards. When the first protective element is in the second position, compared to the first position, it is closer to the main body of the device horizontally. This reduces the lateral dimensions of the lawnmower, minimizing blind spots created by the first protective element when mowing edge areas. The cutting component can then be positioned closer to walls or lawn edges, effectively increasing the lawnmower's coverage.

[0006] In some embodiments, when the first protective member is in the second position, the first protective member is positioned above the cutting assembly.

[0007] When the first protective component moves to the second position relative to the main body of the equipment, by positioning it above the cutting assembly and ensuring that the cutting assembly is not located on the path of the first protective component's horizontal movement, the first protective component can move closer to the interior of the main body of the equipment. This facilitates further reducing the distance between the horizontal projection of the cutting assembly and the horizontal projection of the first protective component, thereby further improving the mower's mowing coverage.

[0008] In some embodiments, when the first protective member is in the second position, the horizontal projection of the first protective member at least partially overlaps with the horizontal projection of the cutting component.

[0009] When the first protective member is in the second position, by making the horizontal projection of the first protective member at least partially overlap with the horizontal projection of the cutting component, the first protective member can move towards a direction closer to the interior of the equipment body, which facilitates further reducing the distance between the horizontal projection of the cutting component and the horizontal projection of the first protective member, so as to further improve the mowing coverage of the lawnmower.

[0010] In some embodiments, when the first protective member is in the second position, the horizontal projection of the device body covers the horizontal projection of the first protective member.

[0011] When the first protective component is in the second position, its horizontal projection is covered by the horizontal projection of the main body of the equipment, meaning the first protective component is completely retracted into the main body of the equipment and will not obstruct the operation of the cutting components. This facilitates edge cutting operations for the lawnmower and also allows for the storage of the first protective component, making it convenient for the lawnmower to be moved or stored.

[0012] In some embodiments, the protective mechanism further includes a second protective member. The second protective member is connected to the side of the first protective member near the working surface and moves with the first protective member. The second protective member extends toward the interior of the equipment body. When the first protective member is in a first position, the second protective member is located between the cutting assembly and the working surface. When the first protective member is in a second position, the second protective member is located above the cutting assembly.

[0013] The second protective component can provide bottom protection for the cutting assembly. When the first protective component is in the first position, the second protective component can form a physical barrier between the cutting assembly and the ground. Even if the user's foot accidentally extends under the cutting assembly, the second protective component can prevent the user's foot from directly contacting the cutting assembly, further improving the safety of the lawnmower.

[0014] In some embodiments, when the first protective member is in the first position, the horizontal projection portion of the second protective member overlaps with the horizontal projection of the cutting assembly.

[0015] When the first protective component is in the first position, the horizontal projection of the second protective component overlaps with the horizontal projection of the cutting component. In this way, the first protective component provides lateral protection for the cutting component, and the second protective component provides bottom protection for the cutting component, while also minimizing the lateral dimensions of the lawnmower.

[0016] In some embodiments, when the first protective member moves from a first position to a second position, the transmission assembly is configured to drive the second protective member to move outward of the device body so that the second protective member avoids the cutting assembly.

[0017] This effectively prevents interference between the first and second protective components and the cutting assembly during the movement of the first protective component from the first position to the second position, thus avoiding damage to the cutting assembly and the first protective component. Furthermore, the transmission assembly drives the movement of the first protective component, ensuring a fixed movement trajectory and improving the stability of its movement.

[0018] In some embodiments, the protective mechanism further includes a support and a first drive member. The transmission assembly is a linkage assembly. The support is connected to the equipment body. One end of the linkage assembly is connected to the support, and the other end of the linkage assembly is connected to the first protective member. The linkage assembly is located above the cutting assembly. The first drive member is connected to the linkage assembly. The first drive member is used to drive the linkage assembly to swing, thereby causing the first protective member to move relative to the equipment body.

[0019] In some embodiments, one end of the linkage assembly is rotatably connected to the support, and the other end of the linkage assembly is rotatably connected to the first protective member. When the first protective member is in the first position, the rotatable connection between the linkage assembly and the support is located above the rotatable connection between the linkage assembly and the first protective member.

[0020] The two ends of the linkage assembly are rotatably connected to the support and the first protective member, respectively. When the first driving member drives the linkage assembly to rotate relative to the support, the first protective member also rotates relative to the linkage assembly. When the first protective member is in the first position, the rotatable connection between the linkage assembly and the support is located above the rotatable connection between the linkage and the first protective member. When the first protective member moves from the first position to the second position, it tends to move outward away from the interior of the equipment body, thus achieving upward movement while simultaneously driving the second protective member to avoid the cutting assembly. When the first protective member moves above the cutting assembly, the linkage assembly can continue to drive the first protective member upward while simultaneously moving it inward towards the interior of the equipment body.

[0021] In some embodiments, the protective mechanism further includes a guide structure. The guide structure is disposed on the support. One end of a linkage assembly slides with the guide structure to move the first protective member from a first position to a second position, and the other end of the linkage assembly is fixedly connected to either the first or second protective member. The guide trajectory of the guide structure includes a first guide segment and a second guide segment connected in sequence. The second guide segment is located above the first guide segment. The first guide segment is configured to guide the first protective member to rise relative to the equipment body while moving away from the support to avoid the cutting assembly. The second guide segment is configured to guide the first protective member to rise relative to the equipment body while moving closer to the support.

[0022] By setting a guide structure, the first guide section and the second guide section of the guide structure can guide the first protective component to move between the first position and the second position, and drive the second protective component to avoid the cutting component, effectively ensuring the smooth and reliable movement of the first protective component and the second protective component.

[0023] In some embodiments, the cutting mechanism further includes a second drive member. The second drive member is connected to the cutting assembly. The second drive member is disposed on the device body. The second drive member is used to drive the cutting assembly to cut grass. The device body has a sealed cavity. The second drive member is located inside the sealed cavity.

[0024] By placing the second drive unit for driving the cutting assembly within a sealed cavity of the main body of the device, rainwater can be prevented from entering the second drive unit when the lawnmower is working on rainy days. This also prevents grass clippings from entering the second drive unit, thereby extending the service life of the second drive unit. Attached Figure Description

[0028] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0030] The terms “first,” “second,” and “third” are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0031] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component present. When a component is considered to be "located" on another component, it can be directly located on the other component or there may be an intervening component present.

[0032] Embodiments of this application provide a lawnmower. The lawnmower includes a main body, a cutting mechanism, and a protective mechanism. The cutting mechanism includes a cutting assembly. The cutting assembly is located below the main body and configured to cut grass on a working surface. The protective mechanism includes a first protective member and a transmission assembly. The transmission assembly is connected to the main body. The transmission assembly is connected to the first protective member. The transmission assembly is used to drive the first protective member to move relative to the main body. The first protective member has at least a first position and a second position. When the first protective member is in the first position, at least a portion of the horizontal projection of the first protective member is outside the horizontal projection of the main body, providing lateral protection to the horizontal height of the cutting assembly. When the first protective member is in the second position, in the horizontal direction, the first protective member is closer to the main body than when it is in the first position.

[0033] When the first protective element is in the first position, it effectively isolates the cutting component from the user or external environment, reducing the risk of injury from accidental contact with the cutting component during mowing. It also effectively prevents obstacles from contacting the cutting component and damaging it. This is suitable for lawnmowers operating in open areas or in work areas where users or pets may be nearby, ensuring the lawnmower meets safety standards. When the first protective element is in the second position, compared to the first position, it is closer to the main body of the device horizontally. This reduces the lateral dimensions of the lawnmower, minimizing blind spots created by the first protective element when mowing edge areas. The cutting component can then be positioned closer to walls or lawn edges, effectively increasing the lawnmower's coverage.

[0034] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] Please see Figure 1 and Figure 2One embodiment of this application provides a lawnmower 100. The lawnmower 100 includes a device body 10, a cutting mechanism 20, and a protective mechanism 30. The cutting mechanism 20 includes a cutting assembly 21. The cutting assembly 21 is located below the device body 10 and configured to cut grass on a working surface. The protective mechanism 30 includes a first protective member 31 and a transmission assembly 33. The transmission assembly 33 is connected to the device body 10. The transmission assembly 33 is connected to the first protective member 31. The transmission assembly 33 is used to drive the first protective member 31 to move relative to the device body 10. The first protective member 31 has at least a first position and a second position. When the first protective member 31 is in the first position, at least a portion of the horizontal projection of the first protective member 31 is outside the horizontal projection of the device body 10, and provides lateral protection to the horizontal height position of the cutting assembly 21. When the first protective member 31 is in the second position, in the horizontal direction, the first protective member 31 is closer to the device body 10 than when it is in the first position.

[0036] When the first protective member 31 is in the first position, it effectively isolates the cutting component 21 from the user or external environment, reducing the risk of injury caused by accidental contact with the cutting component 21 during mowing operations. It also effectively prevents obstacles from contacting the cutting component 21 to avoid damage. This is suitable for situations where the lawnmower 100 is mowing in open areas or in work areas where users, pets, etc., may approach, ensuring the lawnmower 100 meets safety standards. It is understood that, because the horizontal projection of the first protective member 31 is at least partially outside the horizontal projection of the main body 10 when in the first position, it increases the lateral dimensions of the lawnmower 100. When the lawnmower 100 is cutting edges, the first protective member 31 will create a cutting blind spot, thus affecting the mowing coverage of the lawnmower 100. Therefore, when the lawnmower 100 performs lawn mowing operations in the edge area, the first protective member 31 moves to the second position. At this time, compared with the first protective member 31 being in the first position, the first protective member 31 is closer to the main body 10 of the equipment in the horizontal direction. In this way, the lateral dimension of the lawnmower 100 is reduced, which can reduce the cutting dead angle formed by the first protective member 31. The cutting component 21 can be closer to the wall or the edge of the lawn to perform lawn mowing operations, thereby effectively improving the lawn mowing coverage of the lawnmower 100.

[0037] In this application, the transmission component 33 can be directly connected to the main body 10 of the equipment or indirectly connected, such as through the cutting mechanism 20 to the main body 10 of the equipment. This application does not limit this.

[0038] Understandably, when the first protective member 31 is in the first position, while providing lateral protection to the cutting assembly 21, it also forms a physical barrier on the outside of the cutting assembly 21. When the lawnmower 100 is cutting the edges, the cutting assembly 21 has difficulty cutting the edges of the lawn or the areas near obstacles, thus creating cutting blind spots. Therefore, when the lawnmower 100 is cutting the lawn at the edge or near obstacles, the transmission assembly 33 moves the first protective member 31 to the second position to reduce cutting blind spots.

[0039] It should be noted that when the first protective member 31 is in the first position, at least part of the horizontal projection of the first protective member 31 is outside the horizontal projection of the main body 10 of the equipment. This can be either the entire horizontal projection of the first protective member 31 is outside the horizontal projection of the cutting assembly 21, or only part of it is outside the horizontal projection of the cutting assembly 21.

[0040] In this application, the horizontal projection of the first protective member 31 refers to the orthographic projection of the first protective member 31 along the vertical direction of the lawnmower 100 when the lawnmower 100 is moving. The same applies to other components involving horizontal projection. The working surface can be understood as the ground or lawn surface. The horizontal height position of the cutting assembly 21 can be understood as the height of the cutting assembly 21 above the ground when the lawnmower 100 is moving. When the first protective member 31 is in the first position, it can provide lateral protection for the horizontal height position of the cutting assembly 21. Lateral protection can be understood as the first protective member 31, when in the first position, having its horizontal projection at least partially outside the horizontal projection of the cutting assembly 21. In this way, the first protective member 31 can prevent the user or other objects from contacting the cutting assembly 21 from the side of the lawnmower 100.

[0041] It should be further explained that, in the second position compared to the first position, the first protective member 31 is closer to the equipment body 10 in the horizontal direction. "Closer" can be understood as the distance the first protective member 31 extends horizontally. If the first protective member 31 enters the equipment body 10, it indicates that the distance between the first protective member 31 and the equipment body 10 is zero. The horizontal direction in this application does not necessarily mean absolutely horizontal; it can be approximately horizontal, as long as the overall extension direction is horizontal from a macroscopic perspective.

[0042] Please see Figure 3When the first protective member 31 is in the first position, the distance between the outermost edge of the horizontal projection of the first protective member 31 and the center of the main body 10 is defined as d1 in the horizontal direction; when the first protective member 31 is in the second position, the distance between the outermost edge of the horizontal projection of the first protective member 31 and the center of the main body 10 is defined as d2 in the horizontal direction, where d1 > d2. Here, the outermost edge can be understood as: for example, if the first protective member 31 is located on the left and right sides of the lawnmower 100 in the direction of travel, the outermost edge is the leftmost and rightmost edge; if it is located on the front and rear sides of the direction of travel, the outermost edge is the frontmost and rearmost edge.

[0043] It should be noted that, in order to improve the cutting effect of the lawnmower 100 at the edge of the lawn or near the edge of obstacles, the active driving cutting component 21 can be moved to the outside of the lawnmower 100 body 10 to increase the mowing coverage and reduce cutting dead angles. However, by actively driving the cutting component 21 to move to the outside of the body 10, there is a possibility of damage to the core components of the lawnmower 100 due to the movement of the cutting component 21, and it may also cause waterproofing problems for the body 100, thus affecting the service life of the lawnmower 100. This application improves the mowing coverage of the lawnmower 100 when cutting at the edge by changing the position relationship between the first protective component 31 and the cutting component 21, and also improves the maintainability of the lawnmower 100, avoiding the risks caused by changing the position of the cutting component 21, and helping to extend the product life of the lawnmower 100.

[0044] Please see Figure 2 In some embodiments, when the first protective member 31 is in the second position, the first protective member 31 is located above the cutting assembly 21.

[0045] When the first protective member 31 moves to the second position relative to the main body 10 of the equipment, by positioning it above the cutting assembly 21 and ensuring that the cutting assembly 21 is not located on the path of the horizontal movement of the first protective member 31, the first protective member 31 can move towards a direction closer to the interior of the main body 10 of the equipment. This facilitates further reducing the distance between the horizontal projection of the cutting assembly 21 and the horizontal projection of the first protective member 31, thereby further improving the mowing coverage of the lawnmower 100.

[0046] In some embodiments, when the first protective member 31 is in the second position, the horizontal projection of the first protective member 31 at least partially overlaps with the horizontal projection of the cutting component 21.

[0047] When the first protective member 31 is in the second position, by making the horizontal projection of the first protective member 31 at least partially overlap with the horizontal projection of the cutting assembly 21, the first protective member 31 can move in a direction closer to the interior of the main body 10 of the equipment, so as to further reduce the distance between the horizontal projection of the cutting assembly 21 and the horizontal projection of the first protective member 31, thereby further improving the mowing coverage of the lawnmower 100.

[0048] In some embodiments, when the first protective member 31 is in the second position, the horizontal projection of the device body 10 covers the horizontal projection of the first protective member 31.

[0049] When the first protective member 31 is in the second position, the horizontal projection of the main body 10 covers the horizontal projection of the first protective member 31, meaning the first protective member 31 is completely retracted into the main body 10 and will not obstruct the operation of the cutting assembly 21. This facilitates edge cutting operations by the lawnmower 100 and also allows for the storage of the first protective member 31, making it convenient for the lawnmower 100 to be moved or stored.

[0050] In some embodiments, the horizontal projection of the device body 10 overlaps the horizontal projection of the cutting component 21. This overlap can be understood as the horizontal projection of the cutting component 21 being within the horizontal projection of the device body 10, or the boundary of the horizontal projection of the cutting component 21 being tangent to the boundary of the horizontal projection of the device body 10. In other embodiments, the boundary of the horizontal projection of the cutting component 21 is outside the boundary of the horizontal projection of the device body 10.

[0051] Please see Figure 4 In some embodiments, a clearance opening 101 is provided on the side of the device body 10. When the first protective member 31 is in the second position, the first protective member 31 is retracted into the interior of the device body 10 through the clearance opening 101.

[0052] By providing a clearance opening 101 on the side of the device body 10, the first protective member 31 can retract into the device body 10 via the clearance opening 101 when it moves from the first position to the second position relative to the device body 10. Compared to not providing a clearance opening 101, the first protective member 31 would have to move to the second position without interfering with the cutting assembly 21, which would increase the lateral dimension of the entire lawnmower 100. The provision of the clearance opening 101 can make the lawnmower 100 more compact in structure.

[0053] Please see Figure 1 and Figure 2In some embodiments, the protective mechanism 30 further includes a second protective member 32. The second protective member 32 is connected to the side of the first protective member 31 near the working surface and moves with the first protective member 31. The second protective member 32 extends toward the interior of the equipment body 10. When the first protective member 31 is in a first position, the second protective member 32 is located between the cutting assembly 21 and the working surface. When the first protective member 31 is in a second position, the second protective member 32 is located above the cutting assembly 21.

[0054] The second protective member 32 can provide bottom protection for the cutting component 21. When the first protective member 31 is in the first position, the second protective member 32 can form a physical protection between the cutting component 21 and the ground. Even if the user's foot accidentally extends under the cutting component 21, the second protective member 32 can prevent the user's foot from directly contacting the cutting component 21, further improving the safety of the lawnmower 100.

[0055] In some embodiments, the first protective member 31 and the second protective member 32 may be integrally formed.

[0056] In some embodiments, when the first protective member 31 is in the first position, the horizontal projection portion of the second protective member 32 overlaps with the horizontal projection of the cutting assembly 21.

[0057] When the first protective member 31 is in the first position, the horizontal projection of the second protective member 32 overlaps with the horizontal projection of the cutting component 21. In this way, the first protective member 31 provides lateral protection to the cutting component 21 and the second protective member 32 provides bottom protection to the cutting component 21, while also minimizing the lateral dimensions of the lawnmower 100.

[0058] In some embodiments, when the first protective member 31 moves from the first position to the second position, the transmission component 33 is configured to drive the second protective member 32 to move outward of the device body 10 so that the second protective member 32 avoids the cutting component 21.

[0059] This effectively prevents interference between the first protective component 31 and the second protective component 32 and the cutting assembly 21 during the movement of the first protective component 31 from the first position to the second position, thus avoiding damage to the cutting assembly 21 and the first protective component 31. Furthermore, the first protective component 31 is driven to move by the transmission assembly 33, giving it a fixed movement trajectory and helping to improve the stability of its movement.

[0060] Specifically, in some embodiments, during the process of the first protective member 31 moving from the first position to the second position, the transmission component 33 first drives the first protective member 31 to rise while moving away from the interior of the equipment body 10 so that the second protective member 32 avoids the cutting component 21. After the avoidance is completed, the transmission component 33 drives the first protective member 31 to rise while moving closer to the interior of the equipment body 10 until it moves to the second position.

[0061] In some embodiments, when the first protective member 31 moves from the second position to the first position, the transmission component 33 is also configured to drive the first protective member 31 outward away from the equipment body 10 and then lower it so that the second protective member 32 covers the cutting component 21.

[0062] Specifically, in some embodiments, during the process of the first protective member 31 moving from the second position to the first position, the transmission component 33 first drives the first protective member 31 to descend while moving away from the interior of the equipment body 10 so that the second protective member 32 avoids the cutting component 21. After the avoidance is completed, the transmission component 33 then drives the first protective member 31 to descend while moving closer to the interior of the equipment body 10 until it moves to the second position.

[0063] Please see Figure 6 In some embodiments, the protective mechanism 30 further includes a support 34 and a first drive member 35. The transmission assembly 33 is a linkage assembly. The support 34 is connected to the equipment body 10. One end of the linkage assembly is connected to the support 34, and the other end of the linkage assembly is connected to the first protective member 31. The linkage assembly is located above the cutting assembly 21. The first drive member 35 is connected to the linkage assembly. The first drive member 35 is used to drive the linkage assembly to swing, thereby causing the first protective member 31 to move relative to the equipment body 10.

[0064] In some embodiments, one end of the linkage assembly is rotatably connected to the support 34, and the other end of the linkage assembly is rotatably connected to the first protective member 31. When the first protective member 31 is in the first position, the rotatable connection between the linkage assembly and the support 34 is located above the rotatable connection between the linkage assembly and the first protective member 31. It can be understood that "above" here means that the rotatable connection between the linkage assembly and the support 34 is further away from the working surface of the lawnmower 100, rather than being limited to directly above it.

[0065] The two ends of the connecting rod assembly are rotatably connected to the support 34 and the first protective member 31, respectively. When the first driving member 35 drives the connecting rod assembly to rotate relative to the support 34, the first protective member 31 will also rotate relative to the connecting rod assembly. When the first protective member 31 is in the first position, the rotatable connection between the connecting rod assembly and the support 34 is located above the rotatable connection between the connecting rod and the first protective member 31. When the first protective member 31 moves from the first position to the second position, the first protective member 31 tends to move outward away from the interior of the equipment body 10, thereby achieving upward movement while simultaneously driving the second protective member 32 to avoid the cutting assembly 21. When the first protective member 31 moves above the cutting assembly 21, the connecting rod assembly can continue to drive the first protective member 31 to move upward while simultaneously moving it into the interior of the equipment body 10.

[0066] Please see Figure 5 and Figure 6 In some embodiments, the linkage assembly includes two links rotatably connected to opposite sides of the support 34. One link is a first link 331, and the other is a second link 332. The first link 331 includes a first connecting portion 3311 and a second connecting portion 3312 spaced apart. The first connecting portion 3311 is rotatably connected to the support 34, and the second connecting portion 3312 is rotatably connected to either the first protective member 31 or the second protective member 32. The second link 332 includes a third connecting portion 3321 and a fourth connecting portion 3322 spaced apart. The third connecting portion 3321 is rotatably connected to the support 34, and the fourth connecting portion 3322 is rotatably connected to either the first protective member 31 or the second protective member 32. A second driving member 22 is disposed on the support 34. The second driving member 22 connects to the first link 331 or the second link 332 to drive the first link 331 to swing. When the first protective member 31 is in the first position, the first connecting rod 331 is located above the second connecting rod 332; the third connecting portion 3321 is closer to the outer side of the equipment body 10 than the first connecting portion 3311, and the fourth connecting portion 3322 is closer to the outer side of the equipment body 10 than the second connecting portion 3312. Please refer to... Figure 6 In the illustrated embodiment, the second connecting portion 3312 of the first connecting rod 331 is rotatably connected to the first protective member 31, and the fourth connecting portion 3322 of the second connecting rod 332 is rotatably connected to the first protective member 31. When the first protective member 31 is in the first position, the first connecting portion 3311 is located above the second connecting portion 3312, and the third connecting portion 3321 is located above the fourth connecting portion 3322.

[0067] In other embodiments, the linkage assembly may specifically consist of two sets of parallelogram linkage mechanisms, which are rotatably connected to opposite sides of the support 34 and rotatably connected to opposite sides of the first protective member 31 or the second protective member 32, respectively. This application does not limit the specific structure of the linkage assembly; it is sufficient that the linkage assembly, driving the first protective member 31, can avoid the cutting component 21.

[0068] Please see Figure 7 and Figure 8 In some embodiments, the protective mechanism 30 further includes a guide structure 36. The guide structure 36 is disposed on the support 34. One end of the linkage assembly is slidably engaged with the guide structure 36 to move the first protective member 31 from a first position to a second position, and the other end of the linkage assembly is fixedly connected to the first protective member 31 or the second protective member 32. The guide trajectory of the guide structure 36 includes a first guide segment 361 and a second guide segment 362 connected in sequence. The second guide segment 362 is located above the first guide segment 361. The first guide segment 361 is configured to guide the first protective member 31 to rise relative to the equipment body 10 while moving away from the support 34 to avoid the cutting assembly 21. The second guide segment 362 is configured to guide the first protective member 31 to rise relative to the equipment body 10 while moving closer to the support 34. Understandably, the guide trajectory of the guide structure 36 can also guide the first protective member 31 to move from the second position to the first position.

[0069] By setting the guide structure 36, the first guide section 361 and the second guide section 362 of the guide structure 36 can guide the first protective member 31 to move between the first position and the second position, and drive the second protective member 32 to avoid the cutting component 21, effectively ensuring the smooth and reliable movement of the first protective member 31 and the second protective member 32. It also helps to simplify the structure of the transmission component 33.

[0070] In some embodiments, the guide structure 36 may be a guide rail provided on the support 34, or it may be a guide groove provided on the support 34. Figure 7In the illustrated embodiment, the guide structure 36 is a guide groove. The guide groove is located on the support 34. One end of the connecting rod assembly is slidably connected to the guide groove. The second driving member 22 drives the connecting rod assembly to slide within the guide groove. There are two guide grooves. The two guide grooves are spaced apart. One guide groove is the first guide groove 36a, and the other guide groove is the second guide groove 36b. The connecting rod assembly also includes a trajectory connecting rod 333. The trajectory connecting rod 333 includes a first mating part 3331, a second mating part 3332, and a third mating part 3333 arranged sequentially at intervals. The first mating part 3331 is fixedly connected to the first protective member 31 or the second protective member 32. The second mating part 3332 is slidably connected to the second guide groove 36b, and the third mating part 3333 is slidably connected to the first guide groove 36a. The second driving member 22 connects to the trajectory connecting rod 333. The second driving member 22 drives the trajectory connecting rod 333 to slide within the first guide groove 36a and the second guide groove 36b.

[0071] The two guide slots can reduce the swaying or offset of the linkage assembly relative to the support 34, so as to make the movement of the first protective member 31 more stable and reliable.

[0072] Please continue reading Figure 7 and Figure 8 In some embodiments, the linkage assembly further includes a linkage member 334. The linkage member 334 includes a mounting portion 3341 and a linkage portion 3342. The mounting portion 3341 is rotatably connected to the support 34. The linkage portion 3342 has a linkage groove 3342a along the extending direction of the linkage member 334. A third mating portion 3333 is slidably disposed within the linkage groove 3342a. A second driving member 22 is connected to the mounting portion 3341 to drive the linkage member 334 to rotate.

[0073] In this way, the second driving member 22 drives the linkage member 334 to rotate relative to the support 34, thereby causing the second mating part 3332 of the track link 333 to slide in the second guide groove 36b, and the third mating part 3333 to slide in the first guide groove 36a. At the same time, the third mating part 3333 also slides in the linkage groove 3342a. The second driving member 22 does not need to push and pull the track link 333 to slide in the first guide groove 36a and the second guide groove 36b at the same time, but can drive the linkage member 334 to rotate at the mounting part 3341. By driving the track link 333 to rotate clockwise or counterclockwise relative to the support 34, the first protective member 31 can be switched between the first position and the second position.

[0074] Please see Figure 1In some embodiments, the cutting mechanism 20 further includes a second driving member 22. The second driving member 22 is connected to the cutting assembly 21. The second driving member 22 is disposed on the device body 10. The second driving member 22 is used to drive the cutting assembly 21 to cut grass. The device body 10 is provided with a sealed cavity 102. The second driving member 22 is located inside the sealed cavity 102.

[0075] The second drive component 22 for driving the cutting assembly 21 to cut grass is set inside the sealed cavity 102 of the main body 10 of the equipment. This can prevent rainwater from entering the second drive component 22 when the lawnmower 100 is working on rainy days, and can also prevent grass clippings produced by cutting grass from entering the second drive component 22, thereby extending the service life of the second drive component 22.

[0076] In some embodiments, the cutting component 21 can be a rotary cutting device, or it can be an electric shear cutting device, a roller cutting device, etc. Correspondingly, the second driving component 22 can be a motor, a cylinder, etc., and the embodiments of this application do not limit this.

[0077] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
