Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lawn mowers, and particularly relates to an edge trimming device, a lawn mower and a lawn mowing device. BACKGROUND

[0002] At present, the edge trimming device is often used to cut plants outside the cutting range of the lawn mower, and the edge trimming device is usually provided with a grass trimming piece. The grass trimming piece generates sufficient cutting force at the end of the grass trimming piece through high-speed rotation, so as to cut the plants. However, the grass trimming piece is lengthened in the use process due to the extension of the edge trimming device or the entanglement of weeds, which affects the grass trimming effect. When the lawn mower runs in a narrow area, the cutting piece is easy to collide with various obstacles such as trees and flower bed edges, thereby affecting the passability of the lawn mower in the narrow area. SUMMARY

[0003] The present application provides an edge trimming device, a lawn mower and a lawn mowing device, which can keep the grass trimming piece at a preset length and improve the passability of the lawn mower in a narrow area.

[0004] In one aspect, the present application provides an edge trimming device, which comprises a support, a first mounting structure, a grass trimming piece and a cutting piece. The first mounting structure is connected with the support, and the first mounting structure detachably mounts the edge trimming device to the lawn mower. The grass trimming piece is rotationally arranged on the support. The cutting piece is arranged on the support and intersects with the rotation plane of the grass trimming piece. The cutting piece is used to cut the grass trimming piece, so as to keep the grass trimming piece at a preset length. Wherein, the first tangent line of the cutting piece arranged on the support is close to the area of the lawn mower. The first tangent line is the tangent line of the farthest envelope line of the support from the lawn mower, and the first tangent line is perpendicular to the arrangement direction of the edge trimming device and the lawn mower.

[0005] The edge trimming device provided by the application, the support provides support and installation conditions for the first mounting structure and the grass trimming element. Since the edge trimming device comprises the grass trimming element, the grass trimming element is rotatably arranged on the support. Thus, the end of the grass trimming rope is cut by the high-speed rotation of the grass trimming rope to cut irregular vegetation. During use, the grass trimming element will become longer due to the extension of the support or the entanglement of weeds. Since the cutting element is arranged on the support and intersects with the rotation plane of the grass trimming element, the area swept by the rotation of the grass trimming element becomes larger when the grass trimming element becomes longer. The rotating grass trimming element will collide with the cutting element. Thus, the cutting element can cut the part of the grass trimming element that exceeds the preset length by using the force generated by the high-speed rotation of the grass trimming element, so that the grass trimming element can be kept at a preset length. At the same time, since the first tangent line of the cutting element arranged on the support is close to the area of the lawn mower, the cutting element will not protrude relative to the support, and the width of the edge trimming device will not be increased due to the cutting element.

DETAILED DESCRIPTION

[0048] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will further describe the specific technical solutions of the present application with reference to the drawings in the embodiments of the present application. The following embodiments are used to explain the present application, but not to limit the scope of the present application.

[0049] In the embodiments of the present application, the terms "first", "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0050] In addition, in the embodiments of the present application, the orientation terms such as "upper", "lower", "left" and "right" are defined with respect to the orientation of the components shown in the drawings, and it should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and can be changed accordingly according to the change of the orientation of the components placed in the drawings.

[0051] In the embodiments of the present application, unless otherwise specified and limited, the term "connection" should be understood broadly, for example, "connection" can be fixed connection, or detachable connection, or integral; can be directly connected, or indirectly connected through intermediate medium.

[0052] In the embodiments of the present application, the terms "comprising", "containing" or any other variant thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements not only includes those elements, but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without more limitations, the element defined by the phrase "comprising a" does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0053] In the embodiments of the present application, the words "exemplary" or "for example" are used to mean serving as an example or illustration. Any embodiment or design presented as "exemplary" or "for example" in the embodiments of the present application should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of "exemplary" or "for example" is intended to present concepts in a concrete manner.

[0054] The use scenarios of the lawn mowing device are diverse, such as family gardens, park green spaces, golf courses, and various lawn maintenance places, etc. When the lawn grows too long and affects the aesthetics and daily activities, the lawn mowing device can trim the lawn through sharp blades.

[0055] Before using the lawn mowing device to trim the lawn, the working boundary of the lawn mowing device needs to be set. The working boundary can be set by laying physical boundary lines, establishing a virtual boundary through satellite positioning technology, or relying on vision to establish a virtual boundary. However, whether it is a physical boundary or a virtual boundary, when establishing the working boundary, enough edge of the lawn needs to be left to prevent the lawn mowing device from crossing the working boundary, which will cause the lawn mowing device to be unable to work in the edge area of the lawn.

[0056] In addition, the lawn mowing device is usually provided with a grass beating piece. The grass beating piece generates enough cutting force at the end of the grass beating piece through high-speed rotation, so as to cut plants. However, the grass beating piece will become longer during use due to the extension of the grass beating device 2 or the entanglement of weeds, which will affect the grass beating effect.

[0057] In the related art, a cutting piece 24 for cutting the grass beating piece is arranged on the lawn mowing device. However, when the lawn mowing device is maintained or inspected, the operator will often accidentally touch the cutting piece 24, or the grass beating piece 23 or debris cut by the cutting piece 24 will splash, which will cause safety hazards. At the same time, the collision between the cutting piece 24 and the obstacle may cause damage to the lawn mowing device.

[0058] Reference Figure 1 and Figure 2The application provides a grass cutting device, which comprises a mower 1, an edging device 2 and a cutting member 24. The edging device 2 is detachably connected to the mower 1, and the edging device 2 comprises a rotating grass cutting member 23; the cutting member 24 is arranged on the mower 1 or the edging device 2 and located between the mower 1 and the edging device 2; the cutting member 24 intersects with a rotation plane R of the grass cutting member 23, and the cutting member 24 is used for cutting the grass cutting member 23 so that the grass cutting member 23 maintains a preset length.

[0059] In the embodiment of the application, the mower 1 can comprise an intelligent mower or an automatic mower which can autonomously complete the grass cutting work in a set area. The intelligent mower or the automatic mower can realize the functions of automatic walking, grass cutting, grass clippings cleaning, obstacle avoidance and automatic return to charging through the built-in intelligent system. The mower 1 can also comprise a handheld mower which needs to be pushed by a user to walk. The mower 1 walks in the area which needs to be cut through the force applied by the user to the mower 1, and the mower 1 performs cutting operation in the walking process.

[0060] In the embodiment of the application, the edging device 2 can accurately trim the junctions of the edges of lawns, roads, flower beds and walls, so that the edges of the lawns are neat and uniform, and the problem that the traditional mower 1 is difficult to reach or trim completely is reduced. Meanwhile, compared with the traditional manual trimming or edge trimming using the ordinary mower 1, the edging device 2 has higher working efficiency and saves time and labor cost.

[0061] With reference to Figure 2 In the embodiment of the application, the cutting member 24 is used for cutting the grass cutting member 23 so that the grass cutting member 23 maintains a preset length. The preset length of the grass cutting member 23 refers to a specific length that the grass cutting member 23 is designed to or expected to maintain. The length is preset so that the grass cutting member 23 can effectively contact and cut the weeds of the edge of the lawn in the grass cutting process, and meanwhile, the grass cutting effect or the operation of the device will not be affected due to the length being too long or too short. When the grass cutting member 23 becomes long in the use process due to being stretched out of the edging device 2 or being entangled with weeds, the cutting member 24 cuts the grass cutting member 23 or the entangled weeds on the grass cutting member 23, so that the grass cutting member 23 returns to the preset length, thereby maintaining the best working state of the device.

[0062] In the embodiment of the application, the grass cutting member 23 can be a grass cutting rope, which generates sufficient cutting force at the end of the grass cutting rope through high-speed rotation, and is suitable for trimming hard or irregular vegetation such as shrubs and weeds. The grass cutting member 23 can also be a blade type grass cutting member which is composed of sharp blades. The blades cut the lawn through high-speed rotation. The number and shape of the blades of the blade type grass cutting member are various to adapt to different cutting requirements. The grass cutting member 23 can also be other structures which can cut plants.

[0063] With reference toFigure 2 In the embodiment, the edging device 2 further comprises an edging motor 26 and a base 27, the grass cutting member 23 is installed on the base 27, and the edging motor 26 drives the grass cutting member 23 to rotate at a high speed around the base 27 through a transmission system. In this process, the grass cutting member 23 is thrown out and cuts the contacted vegetation under the action of centrifugal force. With the movement of the lawn mower 1 or the edging device 2, the grass cutting member 23 performs cutting work along the edge of the lawn or a specific area, and the lawn is trimmed to the required height and shape.

[0064] The lawn mowing device provided in the embodiment comprises the edging device 2, the grass cutting member 23 is rotationally arranged on the edging device 2, so that the grass cutting member 23 generates sufficient cutting force at the end of the grass cutting rope through high-speed rotation to cut irregular vegetation. When the grass cutting member 23 is lengthened due to the extension of the edging device 2 or the entanglement of weeds during use, the cutting member 24 and the rotating grass cutting member 23 will collide, and the cutting member 24 can cut the area of the grass cutting member 23 exceeding the preset length by using the force generated by the high-speed rotation of the grass cutting member 23, so that the grass cutting member 23 can be kept at the preset length. Since the cutting member 24 is arranged between the lawn mower 1 and the edging device 2, when the cutting member 24 cuts the grass cutting member 23 or the weeds on the grass cutting member 23, the cut grass cutting member 23 and weeds are blocked by the edging device 2 and the lawn mower 1, thereby reducing the safety hazards caused by splashing. At the same time, the edging device 2 and the lawn mower 1 can shield the cutting member 24, thereby reducing the possibility of the operator contacting the cutting member 24 during inspection or maintenance, reducing the safety hazards, and improving the safety of the lawn mowing device.

[0065] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The edging device 2 comprises a support 21, a first mounting structure 22, a grass cutting member 23, and a cutting member 24. The first mounting structure 22 is connected with the support 21, and the first mounting structure 22 detachably installs the edging device 2 to the lawn mower 1. The grass cutting member 23 is rotationally arranged on the support 21. The cutting member 24 is arranged on the support 21, intersects with a rotation plane R of the grass cutting member 23, and is used for cutting the grass cutting member 23 to keep the grass cutting member 23 at a preset length. The first tangent line P of the cutting member 24 arranged on the support 21 is close to the area of the lawn mower 1, the first tangent line P is a tangent line of the farthest envelope line of the support 21 from the lawn mower 1, and the first tangent line P is perpendicular to the arrangement direction of the edging device 2 and the lawn mower 1.

[0066] In the embodiments of the present application, the support 21 provides support and installation conditions for the first mounting structure 22 and the grass beating piece 23, and the material of the support 21 can be selected according to the use scenario. The material of the support 21 can be metal, such as stainless steel or aluminum alloy, etc. The material of the support 21 can also be plastic, such as engineering plastic or reinforced plastic, etc. Engineering plastic has high strength and toughness, and is light in weight and corrosion resistant, and is suitable for use in occasions requiring insulation, corrosion resistance or lightweight design. The strength and rigidity of reinforced plastic can also be improved by adding glass fiber, carbon fiber, etc., while maintaining a relatively light weight. The material of the support 21 is not limited in the present application.

[0067] In the embodiments of the present application, the support 21 can be a collection of all components on the edge beating device 2 except the first mounting structure 22, the grass beating piece 23 and the cutting piece 24. The support 21 can also be an integral structure with the first mounting structure 22. The support 21 can also include a protective structure for protecting the cutting piece, etc.

[0068] In the embodiments of the present application, the first mounting structure 22 detachably installs the edge beating device 2 on the lawn mower 1. The detachable connection mode can be bolt connection, in which corresponding bolt holes or threaded holes are provided on the first mounting structure 22 and the support 21, and fasteners such as bolts, nuts and washers are used, and the bolt is tightened in the nut by rotating the bolt, so as to firmly connect the first mounting structure 22 and the support 21 together. The detachable connection mode can also be buckle connection, in which a buckle structure such as a hook, a slot, etc. is designed on the first mounting structure 22 or the support 21, and the buckle part on the first mounting structure 22 is aligned with the slot or hook on the support 21, and the buckle is tightly combined with the slot or hook by pressing or rotating, etc. The detachable connection mode can also be magnetic attraction connection or other connection modes that can achieve detachable connection.

[0069] Referring to Figure 5 In the embodiments of the present application, the cutting piece 24 intersects with the rotation plane R of the grass beating piece 23. The grass beating piece 23 cuts plants by high-speed rotation and uses the cutting force generated during high-speed rotation. The rotation plane R of the grass beating piece 23 is a virtual plane formed with the mounting hole of the grass beating piece 23 installed on the base 27 as the center and the length of the grass beating piece 23 as the radius when the grass beating piece 23 rotates. This plane is the area swept by the grass beating piece 23 during mowing operation.

[0070] In the embodiment of the present application, the intersection of the cutting member 24 and the rotation plane R of the grass beating member 23 means that the position and angle of the cutting member 24 are designed to intersect with the plane occupied by the grass beating member 23 when rotating. Since the cutting member 24 is used to cut the grass beating member 23, the cutting member 24 is arranged to intersect with the rotation plane R at a point or a line, no matter whether the cutting member 24 is located on the lawn mower 1 or the grass edge trimming device 2, so that the cutting member 24 can contact the grass beating member 23 during the rotation of the grass beating member 23 and cut the part exceeding the preset length.

[0071] In the embodiment of the present application, the first tangent line P is a tangent line of the farthest envelope line of the support 21 from the lawn mower 1. For example, referring to Figure 1 , the side of the support 21 farthest from the lawn mower 1, that is, Figure 1 the leftmost end of the support 21 in the embodiment, the first tangent line P is a tangent line of the leftmost end of the support 21. The tangent line extends in the direction perpendicular to the rotation plane R to form a virtual plane, and the area formed between the side of the support 21 extending from the virtual plane toward the side of the support 21 close to the lawn mower 1 and the farthest end of the support 21 close to the lawn mower 1 is the area where the cutting member 24 can be arranged on the support 21.

[0072] In another embodiment, when the grass edge trimming device 2 further includes other structures or components, if the other structures or components are located at a position farther from the lawn mower 1 than the first tangent line P, the first tangent line P is a tangent line of the farthest envelope line of the structure or component from the lawn mower 1, and the first tangent line P is perpendicular to the arrangement direction of the grass edge trimming device 2 and the lawn mower 1.

[0073] In the embodiment of the present application, the arrangement direction of the grass edge trimming device 2 and the lawn mower 1 refers to the placement or installation direction of the grass edge trimming device 2 relative to the lawn mower 1, or the direction of the grass edge trimming device 2 and the lawn mower 1 as a whole when performing a certain task, for example, the arrangement direction of the grass edge trimming device 2 and the lawn mower 1 when the lawn mower 1 travels along a straight line, and the direction perpendicular to the arrangement direction of the grass edge trimming device 2 and the lawn mower 1 can also be understood as the traveling direction of the lawn mower.

[0074] The edge trimming device 2 provided by the embodiment of the present application, the support 21 provides support and installation conditions for the first installation structure 22 and the grass trimming element 23. Since the edge trimming device 2 comprises the grass trimming element 23, the grass trimming element 23 is rotationally arranged on the support 21. In this way, the end of the grass trimming rope is cut by the high-speed rotation of the grass trimming rope to cut irregular vegetation. During use, the grass trimming element 23 will become longer due to the extension of the support 21 or the entanglement of weeds. Since the cutting element 24 is arranged on the support 21, the cutting element 24 intersects the rotation plane R of the grass trimming element 23. When the grass trimming element 23 becomes longer, the area swept by the rotation of the grass trimming element 23 becomes larger. The rotating grass trimming element 23 will collide with the cutting element 24. In this way, the cutting element 24 can cut the part of the grass trimming element 23 that exceeds the preset length by using the force generated by the high-speed rotation of the grass trimming element 23, so that the grass trimming element 23 can be kept at a preset length. At the same time, since the first tangent line P of the cutting element 24 arranged on the support 21 is close to the area of the lawn mower 1, the cutting element 24 will not protrude relative to the support 21. The cutting element 24 will not increase the width of the edge trimming device 2. When the lawn mower 1 runs to a narrow area, the lawn mower 1 is easy to collide with various obstacles, such as trees, flower bed edges, etc. The first tangent line P of the cutting element 24 arranged on the support 21 close to the area of the lawn mower 1 can effectively control the width of the edge trimming device 2, so that the edge trimming device 2 can keep the grass trimming element 23 at a preset length while improving the passability of the lawn mower 1 in a narrow area.

[0075] With reference to Figure 1 and Figure 4 The present application provides an edge trimming device 2, the cutting element 24 is provided with a first connecting structure 241 matched with the first connecting part 11 on the lawn mower 1, the first connecting part 11 is connected with the first connecting structure 241, and the cutting element 24 is connected to the lawn mower 1.

[0076] In the embodiment of the present application, the first connecting part 11 is arranged on the lawn mower 1, and the first connecting structure 241 matched with the first connecting part 11 is arranged on the cutting element 24. The first connecting part 11 is connected with the first connecting structure 241, and the cutting element 24 is connected to the lawn mower 1. The first connecting part 11 can be a structure on the lawn mower 1, or a structure connected to the lawn mower 1. The first connecting structure 241 can be a part of the cutting element 24, or a structure connected to the cutting element 24. For example, the first connecting structure 241 can be a side edge of the cutting element 24, and the first connecting part 11 can be a groove on the lawn mower 1. The side edge of the cutting element 24 is clamped into the groove on the lawn mower 1, and the connection between the first connecting structure 241 and the first connecting part 11 can be achieved.

[0077] In another embodiment, the first connecting part 11 and the first connecting structure 241 can also be a bolt and nut combination, a threaded hole or a threaded hole is provided on the lawn mower 1, that is, the first connecting part 11, and the cutting member 24 has a corresponding through hole or threaded hole, that is, the first connecting structure 241, and the through hole or threaded hole can be multiple. The first connecting part 11 and the first connecting structure 241 can also be a buckle or other structure, which is not limited in the present application.

[0078] The edge trimming device 2 provided by the embodiment of the present application is connected to the lawn mower 1 through the first connecting part 11 and the first connecting structure 241, and the cutting member 24 is connected to the lawn mower 1, so that the position of the cutting member 24 can meet the demand for different preset lengths of the grass cutting member 23, and the cutting member 24 can be arranged on the lawn mower 1 according to different preset lengths of the grass cutting member 23, thereby improving the flexibility of the installation position of the cutting member 24.

[0079] Referring to Figure 1 In some embodiments of the present application, the cutting member 24 is arranged on the preset area of the support 21, and the preset area is an area on the support 21 close to the lawn mower 1 along the central axis N of the support 21, the central axis N is a virtual straight line parallel to the second direction H and passing through the rotation center of the grass cutting member 23, and the second direction H is perpendicular to the direction in which the edge trimming device 2 and the lawn mower 1 are arranged.

[0080] In the embodiment of the present application, the second direction H is perpendicular to the direction in which the edge trimming device 2 and the lawn mower 1 are arranged, and the direction in which the edge trimming device 2 and the lawn mower 1 are arranged refers to the direction in which the edge trimming device 2 is placed or installed relative to the lawn mower 1, or the direction in which the edge trimming device 2 and the lawn mower 1 as a whole are presented when performing a certain task, for example, when the edge trimming device 2 is installed on one side of the lawn mower 1 in the direction of travel, the direction in which the edge trimming device 2 and the lawn mower 1 are arranged is the direction of travel of the lawn mower 1.

[0081] In the embodiment of the present application, the central axis N is parallel to the second direction H, that is, the central axis N is parallel to the direction in which the edge trimming device 2 and the lawn mower 1 are arranged. When the grass cutting member 23 rotates, the area swept by the grass cutting member 23 will form a circle with the rotation center of the grass cutting member 23 as the center, and the central axis N is a straight line passing through the circle and the rotation center.

[0082] The edge trimming device 2 provided by the embodiment of the present application is arranged on the preset area of the support 21, and the preset area is an area on the support 21 close to the lawn mower 1 along the central axis N of the support 21, so that when the edge trimming device 2 is installed on the lawn mower 1, the cutting member 24 is close to the lawn mower 1, and the lawn mower 1 can shield and protect the cutting member 24, thereby reducing the possibility of the operator contacting the cutting member 24 when checking or maintaining the lawn mower 1, reducing the safety hazard, and improving the safety of the edge trimming device 2. At the same time, it can also reduce the safety hazard caused by the flying of the cut grass cutting member 23 and weeds.

[0083] With reference to Figure 1 In some embodiments of the present application, the cutting member 24 is arranged at a mounting position on the support 21, and the mounting position is a position on the support 21 close to an edge of the lawn mower 1 and intersecting a rotating cylindrical surface, the rotating cylindrical surface being a virtual cylindrical surface formed by a circle enclosing a rotating plane R extending in a first direction Z, and the first direction Z is perpendicular to the rotating plane R.

[0084] In the embodiments of the present application, when the beating member 23 rotates, the end of the beating member 23 rotates to form a circular plane, at this time, the outer edge of the circular plane extends in the first direction Z to form a virtual cylinder, and the surface of the virtual cylinder intersects a region on the support 21 close to an edge of the lawn mower 1 in the first direction Z, and the cutting member 24 can be arranged in the intersecting region. At this time, the cutting member 24 is shielded on both sides by the edge trimming device 2 and the lawn mower 1.

[0085] The edge trimming device 2 provided by the embodiments of the present application has the mounting position on the support 21 close to an edge of the lawn mower 1 and intersecting a rotating cylindrical surface, so that the cutting member 24 is shielded on both sides by the edge trimming device 2 and the lawn mower 1, and when the cutting member 24 cuts the beating member 23 or the weeds rotating with the beating member 23, the safety hazards caused by the cutting of the beating member 23 and the weeds flying are reduced. At the same time, the possibility of the operator contacting the cutting member 24 when checking or maintaining the lawn mower 1 is reduced, and the safety hazards are reduced.

[0086] With reference to Figure 6 and Figure 7 In some embodiments of the present application, the cutting member 24 is arranged on one side of the edge trimming device 2 close to the first mounting structure 22, or the cutting member 24 is arranged on one side of the edge trimming device 2 close to the ground G.

[0087] In the embodiments of the present application, the connection between the cutting member 24 and the edge trimming device 2 can be fixed connection, detachable connection, rotary connection or sliding connection, etc. The connection relationship between the cutting member 24 and the edge trimming device 2 can be adjusted according to the use requirements of the cutting member 24. For example, when the cutting member 24 needs to rotate relative to the edge trimming device 2 to cut the grass wrapped on the edge trimming device 2, the cutting member 24 can be rotatably connected to the edge trimming device 2, and the grass wrapped on the edge trimming device 2 is cut through the rotation of the cutting member 24.

[0088] In the embodiments of the present application, the cutting member 24 can be directly connected to the edge trimming device 2, or the cutting member 24 can be connected to the edge trimming device 2 through other structures. When the cutting member 24 is arranged on the edge trimming device 2, the position of the cutting member 24 needs to be considered to intersect the rotating plane R, so that the cutting member 24 can contact and cut the beating member 23.

[0089] In the embodiment of the present application, when the cutting member 24 is arranged on the edge trimming device 2 close to the side of the lawn mower 1, the cutting member 24 can be arranged on the first mounting structure 22 of the edge trimming device 2, or the cutting member 24 can be arranged on the support 21 close to the side of the lawn mower 1. When the grass cutting member 23 of the edge trimming device 2 cuts the vegetation on the ground G, the grass cutting member 23 is closer to the ground G, and the cutting member 24 is arranged on the side of the edge trimming device 2 close to the ground G, so that the rotating grass cutting member 23 collides with the cutting member 24, thereby cutting the grass cutting member 23 by the cutting member 24.

[0090] The edge trimming device 2 provided by the embodiment of the present application arranges the cutting member 24 on the side of the edge trimming device 2 close to the first mounting structure 22, so that when the edge trimming device 2 is installed on the lawn mower 1, the edge trimming device 2 and the lawn mower 1 can shield and protect the cutting member 24, thereby reducing the risk of misoperation of the cutting member 24. Especially when used in a family or public environment, it helps to protect users and other personnel from accidental injury. The cutting member 24 can also be arranged on the side of the edge trimming device 2 close to the ground G, which can adapt to the edge trimming device 2 with different arrangement heights of the grass cutting member 23.

[0091] With reference to Figure 8 and Figure 9 In some embodiments of the present application, the cutting member 24 includes a base 242 and a cutting portion 243, the base 242 includes two sides extending along a first direction Z, the two sides are oppositely arranged, and at least one side is provided with the cutting portion 243, and the first direction Z is perpendicular to the rotation plane R.

[0092] In the embodiment of the present application, the base 242 refers to the main part of the cutting member 24, and the base 242 serves as the structural basis for supporting and connecting the cutting portion 243. The two sides are parts of the base 242 extending along the first direction Z, that is, with reference to Figure 8 , the two sides are two sides at right angles (or close to right angles) to the rotation plane R. When the grass cutting member 23 rotates, the included angle between the grass cutting member 23 and the two sides is a right angle (or close to a right angle), and this positional relationship can make the cutting portion 243 cut the grass cutting member 23 perpendicularly to the rotation path of the grass cutting member 23, thereby improving the accuracy and efficiency of cutting.

[0093] In the embodiments of the present application, the cutting part 243 is arranged on at least one side surface, that is, one or two side surfaces can be selected to be provided with the cutting part 243 according to actual needs, thereby improving the flexibility of the cutting member 24. For example, when the two side surfaces are both provided with the cutting part 243, no matter the rotation direction of the grass beating member 23 is clockwise or counterclockwise, the cutting part 243 can cut the grass beating member 23 when the grass beating member 23 contacts the cutting member 24. When the side surface of the cutting member 24 that collides with the clockwise rotating grass beating member 23 is provided with the cutting part 243, the grass beating member 23 rotates clockwise, and the cutting part 243 can cut the grass beating member 23; the grass beating member 23 rotates counterclockwise, and the cutting part 243 cannot cut the grass beating member 23.

[0094] In the embodiments of the present application, the cutting part 243 can be a sharp blade or a sharp blade, which can quickly and effectively cut off the grass beating member 23 when the grass beating member 23 rotates through. The cutting part 243 can be installed on the side surface of the base 242 in various ways, such as bolt fixing, welding, buckle connection, etc. The installation mode can be selected according to the shape, material and working environment of the cutting member 24 and other factors. The cutting part 243 can also be integrally formed with the base 242.

[0095] The edge beating device 2 provided by the embodiments of the present application has the following advantages. The base 242 includes two side surfaces extending along the first direction Z, and the grass beating member 23 can contact and collide with the two side surfaces when the grass beating member 23 rotates. Since the two side surfaces are oppositely arranged, and at least one side surface is provided with the cutting part 243, when the grass beating member 23 contacts and collides with the two side surfaces, the cutting parts 243 arranged on the two side surfaces can cut the grass beating member 23. The number of cutting parts 243 and the side surface on which the cutting part 243 is arranged can be adjusted according to the change of the rotation direction of the grass beating member 23 and the use requirements, thereby improving the flexibility of the cutting member 24.

[0096] Reference Figure 10 In some embodiments of the present application, the edge beating device 2 further includes a cover 25. The outer edge of the cover 25 extends towards the ground G side to form an extension 251. The extension 251 encloses an isolation space 252, and the rotation plane R is located in the isolation space 252.

[0097] In the embodiments of the present application, the cover 25 is usually an external covering of the edge beating device 2, which can be made of metal, plastic or other durable materials. The cover 25 can protect the mechanical parts, electrical elements and the like inside the edge beating device 2 from the influence of the external environment, such as dust and flying debris in the external environment. At the same time, the cover 25 can also provide a certain isolation protection for the grass beating member 23, thereby reducing the risk of accidental injury to the user when the grass beating member 23 is working.

[0098] In the embodiment, the outer edge of the cover 25 extends to form an extension 251 towards the ground G side, by extending towards the ground G, the extension 251 can increase the closure and protection of the cover 25 towards the ground G side. At the same time, the extension 251 forms a fence structure with a certain height and boundary towards the ground G side of the cover 25, and the inside of the fence structure forms an isolation space 252.

[0099] In the embodiment, the extension 251 can be directly formed by extending the outer edge of the cover 25 towards the ground G side, so that the extension 251 and the cover 25 have high integrity, which is convenient for production and installation; the extension 251 can also be a separately processed component, and then connected with the cover 25. The length, shape and size of the extension 251 can be adjusted according to the specifications of the edge trimming device 2 and the grass trimming piece 23.

[0100] In the embodiment, referring to Figure 13 , the cutting piece 24 is arranged on the extension 251 close to the side of the lawn mower 1, and the cutting part 243 is located outside the cover 25. The cover 25 can protect the cutting piece 24 and the transmission system from external impact and damage, and at the same time, the cutting part 243 is located outside the cover 25, which ensures that the cutting part 243 can work. The cutting piece 24 can be fixed on the extension 251 by bolts, buckles or other fastening devices, and the cutting piece 24 can also be designed as multiple pieces to increase the cutting area and efficiency.

[0101] Since the cutting piece 24 is arranged on the extension 251 close to the side of the lawn mower 1, the cutting piece 24 can be shielded by the lawn mower 1, reducing the possibility of exposure of the cutting piece 24 and reducing the safety problems caused by the user touching the cutting piece 24 by mistake. Since the cutting part 243 is located outside the cover 25, that is, the cutting part 243 is exposed outside the cover 25, when the grass trimming piece 23 rotates to the position of the cutting piece 24, it can collide with the cutting part 243, thereby cutting the grass trimming piece 23.

[0102] The edge trimming device 2 provided in the embodiment can increase the closure and protection of the cover 25 towards the ground G side when the grass trimming piece 23 is working, because the outer edge of the cover 25 extends to form an extension 251 towards the ground G side. Since the rotation plane R is located in the isolation space 252, the area where the grass trimming piece 23 works is in the isolation space 252, and the extension 251 can more effectively block the flying dust, debris and the like generated when the grass trimming piece 23 works in the isolation space 252, reducing the splashing of dust, debris and the like, thereby reducing the safety hazards.

[0103] Referring to Figure 5In some embodiments of the present application, the shell 25 is provided with a relief opening 253 on the side close to the first mounting structure 22, the relief opening 253 extends along the second direction H, and the second direction H is perpendicular to the arrangement direction of the edging device 2 and the lawn mower 1.

[0104] In the embodiments of the present application, since the edging motor 26 drives the grass cutting member 23 to rotate at high speed around the base 27, the grass cutting member 23 is thrown out and cuts the contacted vegetation under the action of centrifugal force. With the movement of the lawn mower 1 or the edging device 2, the grass cutting member 23 cuts along the edge of the lawn or the specific area to trim the lawn to the required height and shape. Therefore, the shell 25 has a grass cutting opening 254 on the side close to the edge of the lawn or the specific area, that is, the side away from the lawn mower 1. The grass cutting member 23 can be exposed from the isolated space 252 surrounded by the shell 25 through the grass cutting opening 254, which facilitates the contact between the grass cutting member 23 and the vegetation on the edge of the lawn or the specific area.

[0105] In the embodiments of the present application, the arrangement direction of the edging device 2 and the lawn mower 1 refers to the arrangement direction between the edging device 2 and the lawn mower 1 when the edging device 2 is mounted on the lawn mower 1. Since the relief opening 253 extends along the second direction H, and the second direction H is perpendicular to the arrangement direction of the edging device and the lawn mower, when the edging device 2 is mounted on the lawn mower 1, the side of the shell 25 close to the first mounting structure 22, that is, the side of the shell 25 close to the lawn mower 1, will not collide with the lawn mower, and at the same time, the structure between the shell 25 and the lawn mower 1 can be more compact.

[0106] The edging device 2 provided in the embodiments of the present application will vibrate when working, which may cause the side of the shell 25 close to the lawn mower 1 to collide with the lawn mower 1. Therefore, the relief opening 253 provided on the side of the shell 25 close to the lawn mower 1 can reduce the collision between the shell 25 and the lawn mower 1. The provision of the relief opening 253 can make the structure between the shell 25 and the lawn mower 1 more compact, reduce the occupied area of the edging device 2, and also enable the grass cutting member 23 to extend below the lawn mower 1 to cut the plants on the edge below the lawn mower 1 that are not cut by the lawn mower 1.

[0107] Referring to Figure 11 and Figure 12 In some embodiments of the present application, the shell 25 is provided with a shielding member 255, the shielding member 255 is connected with the extension 251, and the side of the shielding member 255 away from the extension 251 extends towards the ground G along the first direction Z, and the first direction Z is perpendicular to the rotation plane R.

[0108] In the embodiments of the present application, the material of the shielding piece 255 can be selected to have good durability, corrosion resistance and impact resistance, so that the shielding piece 255 can withstand the influence of the external environment for a long time. The shape and size of the shielding piece 255 can be adjusted according to the actual needs of the device, so that the shielding piece 255 can effectively cover the target area and provide the required protection effect. The connection between the shielding piece 255 and the extension part 251 can use a connection method that is convenient for the installation and maintenance of the shielding piece 255, so that the shielding piece 255 can be easily replaced or cleaned when needed.

[0109] In the embodiments of the present application, when the shielding piece 255 is connected to the extension structure, it can be connected to the side wall of the extension part 251 away from the isolation space 252. In order to make the connection between the shielding piece 255 and the extension part 251 more stable, referring to Figure 12 , the area where the extension part 251 and the cover 25 meet, the upper surface of the extension part 251 has a height difference relative to the upper surface of the cover 25 in the first direction Z, forming a stepped mounting plane, the shielding piece 255 is attached to the side surface of the extension part 251, and the side of the shielding part close to the cover 25 is bent towards the mounting plane and attached to the mounting plane. In this way, the connection between the shielding piece 255 and the extension part 251 can be more stable, and the bearing capacity of the shielding piece 255 can be improved when the dust and debris flying generates a larger impact force.

[0110] The edge trimming device 2 provided by the embodiments of the present application, the shielding piece 255 is connected to the extension part 251, and the side of the shielding piece 255 away from the extension part 251 extends towards the ground G in the first direction Z, that is, the shielding range of the extension part 255 is extended in the direction of the ground G, the area of the isolation space 252 is increased, and the protection range is increased, thereby further reducing the safety hazard.

[0111] In some embodiments of the present application, the shielding piece 255 is made of an elastic material.

[0112] In the embodiments of the present application, the elastic material used by the shielding piece 255 can be rubber, which is a highly elastic material that can be stretched and twisted over a wide range and quickly returns to its original state after the load is removed. It can adapt to the deformation of the shielding piece 255 when passing through obstacles, and quickly return to its original state after the shielding piece 255 passes through the obstacles, without affecting the performance of the shielding piece 255 in shielding dust and debris.

[0113] The edge trimming device 2 provided by the embodiments of the present application, when performing grass trimming work, when the shielding piece 255 encounters an obstacle on the ground G, since the shielding piece 255 is made of an elastic material, the shielding piece 255 can be raised upwards, or deformed according to the shape and size of the obstacle, so that the shielding piece 255 can pass over the obstacle, thereby improving the passability of the edge trimming device 2.

[0114] In some embodiments of the present application, the cover 25 is provided with a plurality of shielding members 255, and the plurality of shielding members 255 are arranged on the extension 251 around the axis L of the cover 25.

[0115] In the embodiments of the present application, the shape of the cover 25 can be adjusted according to the use requirements. The cover 25 is generally arranged above the grass beating member 23. The shielding members 255 are arranged in a circle or an approximate circle around the axis L of the cover 25, which can improve the protection range and shield specific angles, thereby enhancing the protection performance of the cover 25.

[0116] In the embodiments of the present application, the shape of the shielding member 255 can be adjusted according to actual needs, such as a circle, a square, a polygon, etc. Meanwhile, in order to improve the shielding effect, the surface of the shielding member 255 can be additionally provided with protrusions, grooves, textures, etc. to increase the friction and adhesion.

[0117] The edge beating device 2 provided by the embodiments of the present application has the plurality of shielding members 255 arranged on the cover 25. The plurality of shielding members 255 increase the density and levels of protection. Even if a certain shielding member 255 is damaged or fails, the other shielding members 255 can still continue to function, thereby enhancing the overall protection effect of the shielding members 255. Since the number and distribution of the shielding members 255 can be adjusted according to actual needs, the cover 25 can adapt to different application scenarios and protection requirements. Whether comprehensive protection or local strengthening is required, the layout of the shielding members 255 can be adjusted to achieve the requirements.

[0118] With reference to Figure 14 In some embodiments of the present application, the edge beating device 2 further comprises a mounting seat 28. The mounting seat 28 is arranged on the edge beating device 2. The cutting member 24 is slidingly connected to the mounting seat 28. The mounting seat 28 is formed with a receiving cavity 281. The cutting member 24 can slide into the receiving cavity 281 relative to the mounting seat 28.

[0119] In the embodiments of the present application, the receiving cavity 281 is formed in the mounting seat 28. The receiving cavity 281 in the mounting seat 28 is used to accommodate the cutting member 24. When the cutting member 24 is needed to be used, the cutting member 24 can be slid out of the receiving cavity 281. When the cutting member 24 is not needed to be used, the cutting member 24 can be slid into the receiving cavity 281. When the cutting member 24 is slid into the receiving cavity 281, the safety of the edge beating device 2 can be improved, and the situation that the user accidentally touches the cutting member 24 can be reduced.

[0120] In the embodiments of the present application, the shape of the receiving cavity 281 is matched with the shape of the cutting member 24. When the cutting member 24 is connected to the mounting seat 28 through the sliding assembly, the corresponding sliding assembly can also be arranged in the mounting seat 28, or the sliding assembly can be arranged outside the mounting seat 28.

[0121] In the embodiments of the present application, the cutting member 24 is slidingly connected to the mounting seat 28 and slides into the accommodating cavity 281 relative to the mounting seat 28. The cutting member 24 and the mounting seat 28 can be connected through a sliding connection mechanism. For example, sliding rails are designed on both sides or inside of the mounting seat 28, which can be linear, arc-shaped or other shapes, depending on the path that the cutting member 24 needs to slide, and the bottom or side of the base 242 of the cutting member 24 is designed with sliding blocks or sliding grooves matching the sliding rails, so as to ensure that the cutting member 24 can smoothly slide along the sliding rails.

[0122] The edge trimming device 2 provided by the embodiments of the present application can slide the cutting member 24 into the accommodating cavity 281 relative to the mounting seat 28. When the cutting member 24 is not needed, the cutting member 24 can be slid into the accommodating cavity 281 in the mounting seat 28, which not only reduces the contact of the cutting member 24 with dust, debris and the like in the external environment, reduces the damage or pollution of the cutting member 24, but also reduces the collision and wear of the cutting member 24 during transportation and storage, thereby prolonging the service life of the cutting member 24. When the cutting member 24 is not used, the cutting member 24 can be stored in the accommodating cavity 281, which reduces the space occupied by the whole device, and improves the portability of the device in the case of frequent movement or storage of the edge trimming device 2.

[0123] Referring to Figure 15 In some embodiments of the present application, the edge trimming device 2 further comprises a lifting assembly 29 arranged on the edge trimming device 2, and the cutting member 24 is arranged on the lifting assembly 29. The lifting assembly 29 can move in a first direction Z to move the cutting member 24 to a cutting position or a retracted position. The first direction Z is perpendicular to the rotation plane R.

[0124] In the embodiments of the present application, the lifting assembly 29 can move in the first direction Z. The lifting assembly 29 can include a guide member, and the cutting member 24 is slidingly arranged on the guide member. The guide member extends in the first direction Z, and the cutting member 24 can slide in the extension direction of the guide member. When the cutting of the grass beating member 23 is needed, the cutting member 24 can slide in the first direction Z to a position intersecting with the rotation plane R, that is, the cutting position. When the cutting of the grass beating member 23 is not needed, the cutting member 24 can slide in the first direction Z to a position away from the rotation plane R, that is, the retracted position.

[0125] In the embodiments of the present application, the lifting assembly 29 can further include a driving member arranged on the edge trimming device 2. The output end of the driving member is connected with the cutting member 24. The output end of the driving member can drive the cutting member 24 to move in the first direction Z, so that the cutting member 24 can slide in the first direction Z to the position intersecting with the rotation plane R or the position away from the rotation plane R.

[0126] The edge trimming device 2 provided by the embodiment of the present application is provided with a lifting assembly 29, which can move along the first direction Z. Thus, the position of the cutting member 24 along the first direction Z relative to the rotation plane R can be changed by the lifting assembly 29, that is, the cutting member 24 can be moved to the cutting position or the retracted position, so that the cutting member 24 can be flexibly adapted to different operation conditions. Meanwhile, when the cutting of the grass trimming member 23 is not needed, the cutting member 24 is retracted, which can reduce the damage or pollution of the cutting member 24 and reduce the collision and abrasion of the cutting member 24 during transportation and storage.

[0127] In some embodiments of the present application, the cutting member 24 is detachably arranged on the support 21.

[0128] In the embodiment of the present application, the cutting member 24 is detachably arranged on the support 21. The detachable connection mode can be threaded connection, in which the cutting member 24 and the support 21 are connected by fasteners such as bolts and nuts. For example, threaded holes and threaded columns are arranged on the cutting member 24 and the support 21 respectively, and the cutting member 24 and the support 21 are tightly connected by rotating the nut. The detachable connection mode can also be buckle connection, in which the cutting member 24 and the support 21 are connected by the cooperation of buckles and slots. For example, buckles and slots are arranged on the cutting member 24 and the support 21 respectively, and the cutting member 24 and the support 21 are clamped tightly by the elastic deformation of the buckle. The detachable connection mode can also be other modes.

[0129] The edge trimming device 2 provided by the embodiment of the present application is provided with a lifting assembly 29, which can move along the first direction Z. Thus, the position of the cutting member 24 along the first direction Z relative to the rotation plane R can be changed by the lifting assembly 29, that is, the cutting member 24 can be moved to the cutting position or the retracted position, so that the cutting member 24 can be flexibly adapted to different operation conditions. Meanwhile, when the cutting of the grass trimming member 23 is not needed, the cutting member 24 is retracted, which can reduce the damage or pollution of the cutting member 24 and reduce the collision and abrasion of the cutting member 24 during transportation and storage.

[0130] In some embodiments of the present application, the cutting member 24 includes at least one of the following: a cutting knife, an energy beam generator.

[0131] In the embodiment of the present application, the shape and size of the cutting knife can be adjusted according to requirements. For example, the shape of the cutting knife can be sawtooth-shaped or wavy, so as to improve the cutting effect and reduce the cutting resistance. The material of the cutting knife can be high-carbon steel, stainless steel or hard alloy, so as to improve the wear resistance and cutting efficiency. The cutting knife can reciprocate along the first direction Z relative to the extension part 251, and the cutting knife reciprocates to cut, which is suitable for occasions that require more accurate control of the cutting path or processing of harder vegetation.

[0132] In the embodiment of the present application, the energy beam generator can be a laser cutter, which directly melts or vaporizes the grass cutting piece 23 by using a high-energy laser beam to achieve non-contact cutting. The energy beam generator can also be a plasma cutter, which cuts the grass cutting piece 23 by a high-temperature plasma arc, and is suitable for processing thicker or harder materials. The energy beam generator can also be other structures capable of cutting the grass cutting piece 23.
