Description

Technical field

[0001] The present application relates, but not exclusively, to the technical field of mowing devices, in particular a lawnmower. Background technology

[0002] Lawn mowers can be used in private gardens, parks, golf courses and other areas of lawn care, and serve to cut and maintain lawns.

[0003] Lawn mowers typically consist of a machine body and a handle, with the handle usually located in the center of the machine body. However, the handle design is not ergonomically optimized for the operator, and a larger handle increases the overall dimensions of the lawn mower, making it more difficult for the operator to carry. For example, lifting a larger lawn mower by the handle requires the operator to raise their arm to a higher position, which is tiring. Furthermore, the larger size results in a more loose arrangement of the lawn mower's components, with some parts located far from the handle, making it difficult for the operator to disassemble and service these parts using the handle. In particular, on lawn mowers with a navigation assembly, assistance from the handle is required to remove the navigation assembly.In the prior art, however, the handle is located far from the navigation assembly, which makes it difficult for the operator to remove and attach the navigation assembly using the handle. Content of the utility model

[0004] To solve the aforementioned technical problems, the present application provides a lawnmower that features good handle ergonomics, a compact machine body, and a balanced weight distribution. The present application is implemented through the following technical solution: In the first aspect, an embodiment of the present application provides a lawnmower comprising a machine body, a mowing assembly, a power supply assembly, an adjustment assembly, and a handle, wherein the machine body can move along the driving surface in the direction of travel; wherein the mowing assembly is connected to the machine body; wherein the power supply assembly is attached to the machine body, the power supply assembly being electrically connected to the mowing assembly; wherein the adjustment assembly is attached to the machine body, the adjustment assembly being used to adjust the position of the mowing assembly relative to the machine body; wherein the handle is connected to the machine body; when viewed perpendicular to the driving surface, the longitudinal center axis and the transverse center axis of the machine body are perpendicular to each other, the longitudinal center axis being parallel to the direction of travel;wherein the handle is offset relative to the longitudinal center axis and the transverse center axis, wherein the presetting axis of the handle is inclined relative to the longitudinal center axis so that it passes through the central area of ​​the machine body, wherein the presetting axis of the handle is perpendicular to the handle surface, wherein at least a part of the power supply assembly and at least a part of the adjustment assembly are located on different sides of the presetting axis.

[0005] The technical solution of the present application provides that the machine body serves as a mounting base for the mowing assembly, power supply assembly, adjustment assembly, and handle. The machine body can also move along the driving surface in the direction of travel to facilitate mowing. The mowing assembly is used for mowing, the power supply assembly provides at least current to the mowing assembly, the adjustment assembly can adapt the position of the mowing assembly relative to the machine body to meet different mowing requirements, and the handle makes it easier for the operator to move or operate the lawnmower.Based on this, the handle is offset from the longitudinal center axis of the machine body and also from the transverse center axis; in other words, the handle is attached to the lateral front or rear of the machine body. The presetting axis of the handle is perpendicular to the handle surface, and when the operator lifts the lawnmower by the handle, the direction of the interaction force between the operator and the lawnmower is parallel to the presetting axis. The presetting axis of the handle is inclined relative to the longitudinal center axis so that it passes through the central area of ​​the machine body. At least part of the power supply assembly and at least part of the adjustment assembly are located on opposite sides of the presetting axis, which contributes to structural balance on both sides of the presetting axis and optimizes handle ergonomics.In contrast to technical solutions where the handle is located on the side of the machine body, the handle of the lawnmower described in the present application is offset relative to the longitudinal and transverse central axes. Furthermore, the positions of the handle, the power supply assembly, and the adjustment assembly are relatively balanced, thereby optimizing the handle's ergonomics.

[0006] In some embodiments of the present application, the presetting axis, when viewed perpendicular to the driving surface, has a presetting angle to the longitudinal center axis, wherein the presetting angle is at least 30° and at most 60°.

[0007] The technical solution of the present application provides that setting the presetting angle within a reasonable range facilitates a balanced arrangement of all assemblies on the machine body, optimizes the center of gravity distribution of the lawnmower, and improves the ergonomics of the handle.

[0008] In some embodiments of the present application, the projection of the machine body along the direction perpendicular to the driving surface covers the projection of the handle.

[0009] The technical solution of the present application provides that the projection of the machine body overlaps the projection of the handle; in other words, that the handle is located within the boundaries of the machine body. The arrangement of the handle has only a minor impact on the overall size of the lawnmower, thus making the lawnmower's structure more compact and promoting its miniaturization.

[0010] In some embodiments of the present application, the handle is provided with a through-hole, wherein at least the inner wall of the through-hole forms the handle surface, wherein the handle surface is perpendicular to the presetting axis, and wherein the presetting axis passes through the central region of the handle surface.

[0011] The technical solution of the present application provides that the handle is provided with a through-hole, the inner wall of which serves as part of the gripping surface, so that the operator can grasp the handle with their hand through the through-hole. This increases the contact area between the operator's hand and the handle, thus improving the stability of the handle.

[0012] In some embodiments of the present application, at least two handles are provided and at least two handles are arranged symmetrically with respect to the longitudinal center axis.

[0013] The technical solution of the present application provides that at least two handles are arranged symmetrically to the longitudinal center axis. On the one hand, this makes it easier for the operator to select different handle positions for lifting the lawnmower and thus increases ease of use; on the other hand, the multiple symmetrical handles allow the operator to ensure a uniform application of force to the lawnmower.

[0014] In some embodiments of the present application, the machine body comprises a first end section and a second end section, wherein the first end section and the second end section are arranged one after the other in the direction of travel; wherein at least one of the first end section and the second end section is equipped with the handle.

[0015] The technical solution of the present application provides that the handle can be attached to the first end section and / or second end section of the machine body in order to meet different application scenarios and operating requirements and to improve the adaptability of the lawnmower.

[0016] In some embodiments of the present application, the lawnmower further comprises a navigation assembly, wherein the navigation assembly serves to acquire positioning information of the machine body, wherein the navigation assembly is detachably connected to the machine body; wherein the handle and the navigation assembly are located at the same end section of the machine body.

[0017] The technical solution of the present application provides that the navigation assembly is detachably connected to the machine body to facilitate maintenance of the navigation assembly. The navigation assembly and the handle are arranged at the same end section of the machine body, so that the operator can hold the handle to stabilize the machine body when removing and installing the navigation assembly, thus facilitating the removal and installation of the navigation assembly.

[0018] In some embodiments of the present application, the longitudinal center axis passes through the navigation assembly.

[0019] The technical solution of the present application provides that the navigation assembly is mounted on the longitudinal center axis of the machine body. Whether the navigation assembly is mounted on the machine body or not has only a minor influence on the center of gravity distribution of the lawnmower. Mounting a navigation assembly only slightly affects the driving and steering movements of the lawnmower, thus ensuring good drive consistency.

[0020] In some embodiments of the present application, the lawnmower further comprises an interaction assembly, wherein the interaction assembly is provided for the human-machine interaction of the lawnmower; wherein the interaction assembly and the power supply assembly are arranged side by side; and / or the interaction assembly is located at the edge of the machine body.

The interaction module and the power supply module are arranged side by side, which facilitates the electrical connection and the routing of the cable bundles between the interaction module and the power supply module; the interaction module is located at the edge of the machine body to make operation easier for the operator.

[0022] In some embodiments of the present application, the lawnmower further comprises an environmental perception assembly, wherein the environmental perception assembly serves to detect features of the external environment; wherein the machine body comprises a lateral end section, wherein the presetting axis passes through the lateral end section, and wherein the lateral end section is located below the environmental perception assembly when the handle is lifted, so that the lawnmower leaves the driving surface.

[0023] The technical solution of the present application provides that the environmental perception assembly can detect features of the external environment to serve as a reference for the lawnmower's movement. When the handle is lifted so that the lawnmower leaves the driving surface, the side end section is located below the environmental perception assembly. In other words, when the operator lifts the lawnmower by the handle and the lawnmower naturally hangs downwards, the height of the side end section is below the height of the environmental perception assembly, thus reducing the likelihood of the environmental perception assembly colliding with obstacles and thereby protecting it.

[0024] In the second aspect, an embodiment of the present application provides a lawnmower comprising a machine body, a navigation assembly, and a handle, wherein the machine body can move along the driving surface in the direction of travel; wherein the navigation assembly is detachably connected to the machine body, the navigation assembly serving to acquire the navigation information of the machine body; wherein the handle is connected to the machine body, the navigation assembly and the handle being arranged at the same end section of the machine body; when viewed perpendicular to the driving surface, the longitudinal center axis and the transverse center axis of the machine body are perpendicular to each other, the longitudinal center axis running parallel to the direction of travel;wherein the handle is offset relative to the longitudinal center axis and the transverse center axis, wherein the presetting axis of the handle is inclined relative to the longitudinal center axis so that it passes through the central area of ​​the machine body, wherein the presetting axis of the handle is perpendicular to the handle surface.

[0025] The technical solution of the present application provides that the machine body serves as a mounting base for the navigation assembly and the handle. The machine body can also move along the driving surface in the direction of travel to facilitate mowing operations. The navigation assembly serves to detect the position of the machine body so that the lawnmower can perform route planning, and the handle makes it easier for the operator to move or operate the lawnmower.Based on this design, the handle is offset from both the longitudinal and transverse centers of the machine body; in other words, the handle is mounted on the lateral front or rear of the machine body. The handle's presetting axis is perpendicular to the handle surface, and when the operator lifts the lawnmower by the handle, the direction of the interaction force between the operator and the lawnmower is parallel to the presetting axis, allowing the operator to easily lift the lawnmower by the handle. The navigation assembly and the handle are located at the same end section of the machine body, so that when removing and attaching the navigation assembly, the operator can hold the handle to stabilize the machine body, thus facilitating the removal and attachment of the navigation assembly.In contrast to technical solutions where the handle is located on the side of the machine body, the handle of the lawnmower described in the present application is offset relative to the longitudinal and transverse central axes. Furthermore, the handle and the navigation assembly are located at the same end section of the machine body, which makes it easier for the operator to attach and detach the navigation assemblies using the handle.

[0026] In some embodiments of the present application, the machine body comprises a first end section and a second end section, wherein the first end section and the second end section are arranged one after the other in the direction of travel; wherein at least one of the first end section and the second end section is equipped with the handle.

[0027] The technical solution of the present application provides that the handle can be attached to the first end section and / or second end section of the machine body in order to meet different application scenarios and operating requirements and to improve the adaptability of the lawnmower.

[0028] In some embodiments of the present application, the longitudinal center axis passes through the navigation assembly.

[0029] The technical solution of the present application provides that the longitudinal center axis runs through the navigation assembly; in other words, the navigation assembly is mounted in the central region of the machine body. Whether the navigation assembly is mounted on the machine body or not has only a minor influence on the center of gravity of the lawnmower. Mounting a navigation assembly has only a minimal effect on the driving and steering movements of the lawnmower, thus ensuring good drive consistency.

[0030] In some embodiments of the present application, the lawnmower further comprises a mowing assembly, a power supply assembly, and an adjustment assembly, wherein the mowing assembly is connected to the machine body; wherein the power supply assembly is attached to the machine body, wherein the power supply assembly is electrically connected to the mowing assembly; wherein the adjustment assembly is attached to the machine body, wherein the adjustment assembly serves to adjust the position of the mowing assembly relative to the machine body; wherein at least a part of the power supply assembly and at least a part of the adjustment assembly are located on different sides of the presetting axis when viewed perpendicular to the driving surface.

[0031] The technical solution of the present application provides that the mowing assembly serves for mowing, the power supply assembly provides at least current to the mowing assembly, and the adjustment assembly can adjust the position of the mowing assembly relative to the machine body to meet different mowing requirements. The presetting axis of the handle is inclined relative to the longitudinal center axis and runs through the central area of ​​the machine body, with at least a part of the power supply assembly and at least a part of the adjustment assembly being located on opposite sides of the presetting axis. This contributes to structural balance on both sides of the presetting axis and optimizes handle ergonomics.

[0032] In some embodiments of the present application, the presetting axis has a presetting angle to the longitudinal center axis, wherein the presetting angle is at least 30° and at most 60°.

[0033] The technical solution of the present application provides that setting the presetting angle within a reasonable range facilitates a balanced arrangement of all assemblies on the machine body, optimizes the center of gravity distribution of the lawnmower, and improves the ergonomics of the handle.

[0034] In some embodiments of the present application, the projection of the machine body along the direction perpendicular to the driving surface covers the projection of the handle.

[0035] The technical solution of the present application provides that the projection of the machine body overlaps the projection of the handle; in other words, that the handle is located within the boundaries of the machine body.

Specific embodiments

[0044] To clarify the purpose, technical solutions, and advantages of the embodiments of the present application, the various embodiments of the present application are described in detail below in conjunction with the accompanying drawings. The following exemplary embodiments serve to illustrate the application but are not intended to limit its scope.

[0045] In the embodiment of the present application, the terms "first" and "second" are used for descriptive purposes only and should not be interpreted as indicating or implying a relative meaning, or as an implicit indication of the number of technical features referred to. Thus, a feature designated as "first" and "second" may explicitly or implicitly include one or more such features. In the description of the embodiment of the present application, "several" means two or more, unless otherwise specified.

[0046] Furthermore, in the embodiment of the present application, the directional terms "top", "bottom", "left", and "right" are defined relative to the schematic arrangement of the components in the figures. It should be understood that these directional terms represent relative concepts used for relative description and clarification, and that they may change accordingly if the arrangement of the components in the figures changes.

[0047] In the embodiment of the present application, unless expressly stated and defined otherwise, the term "connection" is to be understood in the broadest sense; for example, the "connection" may be a fixed connection, a detachable connection or a unit; it may be a direct connection or an indirect connection via an intermediate medium.

[0048] In the embodiment of the present application, the term "comprise," "contain," or any other variation thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a set of elements includes not only those elements but also other elements not expressly listed or inherent in such process, method, article, or device. In the absence of further limitations, elements defined by the phrase "comprises a..." do not preclude the presence of additional identical elements in the process, method, article, or device that comprise the elements.

[0049] In the embodiment of the present application, terms such as "for example" or "for instance" are used to present examples, illustrations, or explanations. Embodiments or design variants designated as "for example" or "for instance" in the embodiment of the present application are not to be interpreted as being preferred or more advantageous than other embodiments or design variants. More precisely, the terms "for example" or "for instance" serve to present the corresponding concepts in a concrete manner.

[0050] The embodiment of the present application provides a lawnmower, wherein lawnmowers can be used in private gardens, parks, golf courses and other areas of lawn care and serve for cutting and maintaining lawns. Lawnmowers can be designed in the form of an internal combustion engine, an electric motor or a hybrid drive.

[0051] In some designs, the lawnmower comprises a machine body and a handle attached to the body, the handle being intended to facilitate transport. The handle is usually located in the center of the machine body. However, the handle design is not ergonomically optimized for the operator, and a larger handle increases the overall dimensions of the lawnmower, making it more difficult to transport. For example, lifting a larger lawnmower by the handle requires the operator to raise their arm to a higher position, which is strenuous. Furthermore, the larger size results in a more dispersed arrangement of the lawnmower's components, with some parts located far from the handle, making it difficult for the operator to disassemble and maintain these parts using the handle.Especially with lawnmowers equipped with a navigation unit, the handle is required for disassembling the navigation unit. However, in current designs, the handle is located far from the navigation unit, making it difficult for the operator to remove and reattach the navigation unit using the handle.

[0052] Before the embodiments of the present application are explained in more detail, the terms and terminology used in the embodiments of the present application will be explained. The terms and terminology used in the embodiments of the present application are to be understood according to the following definitions. 1) Driving surface: The surface that serves to support and guide the lawnmower and is in contact with the lawnmower's chassis. For example, when operating a lawnmower on the lawn, the lawn surface can be considered the driving surface. It should be explained that the driving surface can be either a horizontal plane or a plane inclined relative to the horizontal. 2) Direction of travel: The direction of travel refers to the direction in which the lawnmower travels along the driving surface and can also be understood as the direction in which the rear end section of the lawnmower points towards the front end section. 3) Central axis: The axis that passes through the geometric center of the component. Using the machine body as an example, the longitudinal central axis refers to the central axis of the machine body that runs parallel to the running surface and parallel to the direction of travel; the transverse central axis refers to the central axis of the machine body that runs parallel to the running surface and perpendicular to the direction of travel. 4) Central Region: This encompasses the area around the geometric center of the component. The boundary of the central region can be defined by the dimensions of the component. Using the machine body as an example, the central region of the machine body includes the geometric center of the machine body as well as the area within a defined distance from this geometric center. The ratio of this boundary distance to the length of the machine body in the corresponding direction is greater than 0 and at most 0.2. Alternatively, the central region of the machine body has a preset distance from the edge of the machine body, where the ratio of the preset distance to the size of the machine body in the corresponding direction is at least 0.3 and at most 0.45. 5) Grip surface: The surface that comes into contact with the operator's palm and fingers when holding the handle. The grip surface can be flat or curved. 6) Preset axes: Axes that pass through the component and are related to the geometric center, surface or shape of the component, for example axes that run parallel to the radial direction of the component, axes that are perpendicular to the component surface, or axes that pass through the geometric center of the component.

[0053] As an example of the handle, the handle's presetting axis is perpendicular to the handle surface. For a curved handle surface, the presetting axis runs through the center point of the curved surface and extends along the normal direction to this point. Furthermore, the presetting axis traverses the central area of ​​the machine body.

[0054] It should be noted that, unless otherwise stated, the descriptions in the embodiment of the present application relating to the longitudinal center axis, the transverse center axis and the presetting axis are based on a view perpendicular to the driving surface.

[0055] The lawnmower of the embodiment of the present application with reference to Fig. 1, Fig. 2 and Fig. 3 comprises a machine body 100, a mowing assembly 200, a power supply assembly 300, an adjustment assembly 400, and a handle 500, wherein the machine body 100 can move along the direction of travel X in the driving surface M; wherein the mowing assembly 200 is connected to the machine body 100; wherein the power supply assembly 300 is attached to the machine body 100, the power supply assembly 300 being electrically connected to the mowing assembly 200; wherein the adjustment assembly 400 is attached to the machine body 100, the adjustment assembly 400 being used to adjust the position of the mowing assembly 200 relative to the machine body 100; wherein the handle 500 is connected to the machine body 100; When viewed perpendicular to the driving surface M, the longitudinal center axis L1 and the transverse center axis L2 of the machine body 100 are perpendicular to each other, with the longitudinal center axis L1 running parallel to the direction of travel X;wherein the handle 500 is offset relative to the longitudinal center axis L1 and the transverse center axis L2, wherein the presetting axis L3 of the handle 500 is inclined relative to the longitudinal center axis L1 so that it passes through the central area 110 of the machine body 100, wherein the presetting axis L3 of the handle 500 is perpendicular to the grip surface 510 of the handle 500, wherein at least a part of the power supply assembly 300 and at least a part of the adjustment assembly 400 are located on different sides of the presetting axis L3.

[0056] In the embodiment of the present application, the machine body 100 is the main structure of the lawn mower. The machine body 100 can comprise a housing and a drive assembly. The housing provides a mounting base and protection for the mowing assembly 200, the power supply assembly 300, the adjustment assembly 400, etc.; the drive assembly propels the lawn mower along the driving surface M, and the drive assembly can comprise drive wheels, a drive motor, a drive battery, etc.

[0057] In the embodiment of the present application, the mowing assembly 200 serves to cut and trim herbaceous plants, for example, to cut the grass evenly on a lawn. The mowing assembly 200 is attached to the machine body 100 on the side facing the driving surface M and the mowing assembly 200 can comprise a cutting plate, a grass line device, etc.

[0058] In the embodiment of the present application, the power supply assembly 300 can be a battery or a solar panel for power supply; the power supply assembly 300 can also be a device that provides energy through the use of fuel, for example, an internal combustion engine.

[0059] In the embodiment of the present application, the adjustment assembly 400 can be arranged between the machine body 100 and the mowing assembly 200. The adjustment assembly 400 can move the mowing assembly 200 relative to the machine body 100 by rotating, sliding, or other types of movement. The adjustment assembly 400 can adjust the position of the mowing assembly 200 relative to the machine body 100 in a direction parallel to the driving surface M as well as in a direction perpendicular to the driving surface M. For example, the adjustment assembly 400 adjusts the mowing assembly 200 in the direction perpendicular to the driving surface M, thereby changing the distance between the mowing assembly 200 and the driving surface M to meet different mowing height requirements.

[0060] In the embodiment of the present application, the connection of the handle 500 to the machine body 100 can be a detachable connection such as a plug connection, a threaded connection or a fastener connection, or a permanent connection such as welding, gluing, riveting or integral injection molding. In some embodiments, the handle 500 and the machine body 100 are integrally formed.

[0061] In the embodiment of the present application, the handle 500 is offset relative to the longitudinal center axis L1, that is, the longitudinal center axis L1 does not pass through the handle 500, but the handle 500 is located on one side of the longitudinal center axis L1; correspondingly, the handle 500 is offset relative to the transverse center axis L2, such that the transverse center axis L2 does not pass through the handle 500 and the handle 500 is located on one side of the transverse center axis L2. The technical solution of the embodiment of the present application provides that the handle 500 is offset both relative to the longitudinal center axis L1 and relative to the transverse center axis L2.

[0062] For example, when viewed perpendicular to the driving surface M, a planar coordinate system is established with the longitudinal center axis L1 and the transverse center axis L2. The longitudinal center axis L1 and the transverse center axis L2 divide this plane into four regions. The handle 500 can be located in one of the four regions without touching the longitudinal center axis L1 or the transverse center axis L2.

[0063] In the embodiment of the present application, at least a part of the power supply assembly 300 and at least a part of the adjustment assembly 400 are located on opposite sides of the presetting axis L3. That is, the main parts of the power supply assembly 300 and the adjustment assembly 400 are located on opposite sides of the presetting axis L3, with the main part referring to the part whose mass fraction is at least 0.6 and at most 1. In some examples, the main part of the power supply assembly 300 is located on one side of the presetting axis L3, while the entire adjustment assembly 400 is arranged on the other side of the presetting axis L3.

[0064] The technical solution of the embodiment of the present application provides that the machine body 100 serves as a mounting base for the mowing assembly 200, the power supply assembly 300, the adjustment assembly 400, and the handle 500. The machine body 100 can also move along the direction of travel X on the driving surface M to facilitate mowing. The mowing assembly 200 is used for mowing, the power supply assembly 300 provides at least current to the mowing assembly 200, the adjustment assembly 400 can adjust the position of the mowing assembly 200 relative to the machine body 100 to meet different mowing requirements, and the handle 500 facilitates the operator's movement or operation of the lawnmower.

[0065] Based on this, the handle 500 is offset relative to the longitudinal center axis L1 of the machine body 100 and also relative to the transverse center axis L2; ​​in other words, the handle 500 is attached to the lateral front or rear of the machine body 100;The presetting axis L3 of the handle 500 is perpendicular to the grip surface 510 of the handle 500, and when the operator lifts the lawnmower by the handle 500, the direction of the interaction force between the operator and the lawnmower is parallel to the presetting axis L3, wherein the presetting axis L3 of the handle 500 is inclined relative to the longitudinal center axis L1 and runs through the central area 110 of the machine body 100, wherein at least a part of the power supply assembly 300 and at least a part of the adjustment assembly 400 are located on opposite sides of the presetting axis L3, which contributes to the structural balance on both sides of the presetting axis L3 and optimizes the handle ergonomics of the handle 500.

[0066] In contrast to technical solutions where the handle 500 is arranged on the side of the machine body 100, the handle 500 of the lawnmower described in the present application is arranged offset relative to the longitudinal center axis L1 and the transverse center axis L2. Furthermore, the positions of the handle 500, the power supply assembly 300, and the adjustment assembly 400 are relatively balanced, thereby optimizing the ergonomics of the handle 500.

[0067] In some embodiments of the present application, with reference to Fig. 2 The presetting axis L3, when viewed perpendicular to the driving surface M, has a presetting angle θ to the longitudinal center axis L1, where the presetting angle θ is at least 30° and at most 60°.

[0068] In the embodiment of the present application, the presetting angle θ can be set according to the design requirements. If the presetting angle θ is set smaller, the handle 500 is located closer to the longitudinal center axis L1, which facilitates the arrangement of the individual assemblies on the machine body 100 along the longitudinal direction or symmetrically to the longitudinal center axis L1; if the presetting angle θ is set larger, the handle 500 is located closer to the transverse center axis L2, which facilitates the arrangement of the individual assemblies on the machine body 100 along the transverse direction or symmetrically to the transverse center axis L2.

[0069] In the embodiment of the present application, the preset angle θ is at least 30° and at most 60°, wherein the preset angle θ can assume any value within this range; for example, the preset angle θ can be at least 30° and at most 45°, for example 30°, 35°, 40°, 45°, etc. Or the preset angle θ can be at least 45° and at most 60°, for example 45°, 50°, 55°, 60°, etc.

[0070] The technical solution of the embodiment of the present application provides that setting the presetting angle θ within a reasonable range facilitates a balanced arrangement of all assemblies on the machine body 100, optimizes the center of gravity distribution of the lawnmower and improves the grip ergonomics of the handle 500.

[0071] In some embodiments of the present application, with reference to Fig. 2 and Fig. 3 covers the projection of the machine body 100 and the projection of the handle 500 in a projection perpendicular to the driving surface M.

[0072] In the embodiment of the present application, the projection of the machine body 100 covers the projection of the handle 500, wherein the projection size of the machine body 100 is larger than the projection size of the handle 500 and the projections of the machine body 100 and the handle 500 overlap. In other words, when viewed perpendicular to the driving surface M in the direction of the lawnmower, the machine body 100 will completely cover the handle 500.

[0073] In the embodiment of the present application, the handle 500 can be positioned either near the edge of the machine body 100 or near the central region 110 of the machine body 100. In some examples, the handle 500 is positioned close to the edge of the machine body 100, for example projected along the direction perpendicular to the travel surface M, with the projection edge of the handle 500 partially overlapping the projection edge of the machine body 100 to facilitate gripping for the operator.

[0074] The technical solution of the embodiment of the present application provides that the projection of the machine body 100 covers the projection of the handle 500; in other words, the handle 500 is located within the boundary of the machine body 100. The arrangement of the handle 500 has only a minor influence on the overall size of the lawnmower, thereby making the structure of the lawnmower more compact and promoting its miniaturization.

[0075] In some embodiments of the present application, with reference to Fig. 1, Fig. 2 and Fig. 4 The handle 500 is provided with a through hole 520, wherein at least the inner wall of the through hole 520 forms the handle surface 510, wherein the presetting axis L3 runs through the central area of ​​the handle surface 510.

[0076] In the embodiment of the present application, the through-hole 520 on the handle 500 can be a hole that penetrates the handle 500, or the handle 500 is connected to the machine body 100, with a through-hole 520 being formed between the two.

[0077] In the embodiment of the present application, the shape of the through-hole 520 can be round, elliptical, square, triangular, trapezoidal, track-shaped, or similar. In one example, the through-hole 520 passes through the handle 500, wherein the through-hole 520 is a right-angled triangle and the handle 500 forms a gripping surface 510 on the side of the hypotenuse; in another example, the through-hole 520 is track-shaped, wherein the central part has a square structure and the two ends of the square structure are semicircular.

[0078] In the embodiment of the present application, the presetting axis L3 runs through the middle part of the grip surface 510; in other words, the presetting axis L3 runs through the middle area of ​​the handle 500, so that when the handle 500 is handled by the operator, the force is distributed more evenly.

[0079] The technical solution of the embodiment of the present application provides that the handle 500 is provided with a through-hole 520, the inner wall of the through-hole 520 serving as part of the gripping surface 510, so that the operator can grasp the handle 500 with their hand through the through-hole 520. This increases the contact area between the operator's hand and the handle 500, which improves the stability of the handle.

[0080] In some embodiments of the present application, with reference to Fig. 1 and Fig. 4 at least two handles 500 are provided and at least two handles 500 are arranged symmetrically with respect to the longitudinal center axis L1.

[0081] In the embodiment of the present application, the handle 500 can be a single handle or comprise several handles 500 (including two). Several handles 500 on different sides of the longitudinal center axis L1 are arranged symmetrically to the longitudinal center axis L1.

[0082] For example, the projection of the machine body 100 perpendicular to the driving surface M is approximately square, and there are two handles 500, the two handles 500 being located at two corners of the machine body 100 and arranged symmetrically to the longitudinal center axis L1.

[0083] The technical solution of the embodiment of the present application provides that at least two handles 500 are arranged symmetrically to the longitudinal center axis L1. On the one hand, this makes it easier for the operator to select different positions for lifting the lawnmower and thus increases ease of use; on the other hand, the multiple symmetrical handles 500 allow the operator to ensure a uniform application of force to the lawnmower.

[0084] In some embodiments of the present application, with reference to Fig. 2 and Fig. 4 The machine body 100 comprises a first end section 120 and a second end section 130, wherein the first end section 120 and the second end section 130 are arranged one after the other in the direction of travel X; wherein at least one of the first end section 120 and of the second end section 130 is equipped with the handle 500.

[0085] In the embodiment of the present application, the first end section 120 can be the front end section of the machine body 100; in other words, as the machine body 100 travels forward along the track surface M, the first end section 120 is located in front of the second end section 130, and the first end section 120 passes the track surface M in front of the second end section 130; accordingly, the second end section 130 is the rear end section of the machine body 100.

[0086] In some examples, a handle 500 is attached to the first end section 120 of the machine body 100; in other examples, a handle 500 is attached to the second end section 130 of the machine body 100; in still other examples, handles 500 are attached to both the first end section 120 and the second end section 130 of the machine body 100. The handles 500 at the first end section 120 and at the second end section 130 can be located on the same or on opposite sides of the longitudinal center axis L1.

[0087] In the embodiment of the present application, the first end section 120 can be equipped with one or more handles 500; the second end section 130 can also be equipped with one or more handles 500. In some examples, one handle 500 is attached to the second end section 130 of the machine body 100; in other examples, two handles 500 are attached to the second end section 130 of the machine body 100; the two handles 500 being arranged symmetrically with respect to the longitudinal center axis L1.

[0088] The technical solution of the embodiment of the present application provides that the handle 500 can be attached to the first end section 120 and / or to the second end section 130 of the machine body 100 in order to meet different application scenarios and operating requirements and to improve the adaptability of the lawnmower.

[0089] In some embodiments of the present application, with reference to Fig. 1 and Fig. 4 The lawnmower further comprises a navigation assembly 600, wherein the navigation assembly 600 serves to acquire positioning information of the machine body 100, wherein the navigation assembly 600 is detachably connected to the machine body 100; wherein the handle 500 and the navigation assembly 600 are located at the same end section of the machine body 100.

[0090] In the embodiment of the present application, the navigation assembly 600 serves to acquire the positioning information of the machine body 100 so that the machine body 100 can plan its travel path based on this positioning information and perform highly precise mowing. The navigation assembly 600 can include a laser scanner, an ultrasonic localizer, a satellite localizer, and similar components. For example, the navigation assembly 600 includes a real-time kinematic (RTK) positioning assembly that enables highly precise positioning based on global satellite navigation systems.

[0091] In the embodiment of the present application, the detachable connection of the navigation assembly 600 to the machine body 100 can be a snap connection, a threaded connection, a fastening connection, or the like. For example, the navigation assembly 600 is attached to the machine body 100 by means of screws or other fasteners. The navigation assembly 600 can be mounted on the side of the machine body 100 facing away from the driving surface M to facilitate disassembly and assembly.

[0092] In the embodiment of the present application, the navigation assembly 600 and the handle 500 are located on the same end section of the machine body 100. In other words, the end section of the machine body 100 to which the navigation assembly 600 is attached is also equipped with the handle 500. However, the end section of the machine body 100 to which the handle 500 is attached can function without the navigation assembly 600. In some examples, the navigation assembly 600 is attached to the first end section 120 of the machine body 100, the first end section 120 also being equipped with a handle 500; in other examples, the navigation assembly 600 is attached to the second end section 130 of the machine body 100, the second end section 130 also being equipped with a handle 500.

[0093] The technical solution of the embodiment of the present application provides that the navigation assembly 600 and the machine body 100 are detachably connected to each other, which facilitates the maintenance of the navigation assembly 600. The navigation assembly 600 and the handle 500 are attached to the same end section of the machine body 100, so that when removing and attaching the navigation assembly 600, the operator can hold the handle 500 to stabilize the machine body 100, thus facilitating the removal and attachment of the navigation assembly 600.

[0094] In some embodiments of the present application, with reference to Fig. 1 and Fig. 4 The longitudinal center axis L1 runs through the navigation assembly 600.

[0095] In the embodiment of the present application, the projections of the longitudinal center axis L1 and the navigation assembly 600 overlap when viewed perpendicular to the driving surface M. In other words, in the direction parallel to the transverse center axis L2, the navigation assembly 600 is arranged in the central part of the machine body 100.

[0096] In some embodiments, the end section of the machine body 100, to which the navigation assembly 600 is attached, is equipped with two handles 500. The navigation assembly 600 is located between the two handles 500, so that the operator can select the easier-to-handle handle 500 as needed.

[0097] The technical solution of the embodiment of the present application provides that the navigation assembly 600 is attached to the longitudinal center axis L1 of the machine body 100. Whether the navigation assembly 600 is mounted on the machine body 100 or not has only a minor influence on the center of gravity distribution of the lawnmower. The installation of a navigation assembly 600 only slightly affects the driving and steering movements of the lawnmower, thus ensuring good drive consistency.

[0098] In some embodiments of the present application, with reference to Fig. 4 and Fig. 5 the lawnmower further comprises an interaction assembly 700, wherein the interaction assembly 700 is provided for the human-machine interaction of the lawnmower; wherein the interaction assembly 700 and the power supply assembly 300 are arranged side by side; and / or the interaction assembly 700 is located at the edge of the machine body 100.

[0099] In the embodiment of the present application, the interaction assembly 700 serves for human-machine interaction. The interaction assembly 700 can include input assemblies such as buttons, keyboard, microphone, touchpad, etc., and can also include output assemblies such as speakers, screen, indicator lights, etc. In some examples, the interaction assembly 700 includes a screen and an emergency stop switch, the emergency stop switch being used to interrupt the power supply to the power supply assembly 300 or to stop the operation of the lawnmower. The interaction assembly 700 can be mounted on the side of the machine body 100 facing away from the driving surface M to facilitate operation.

[0100] In the embodiment of the present application, the interaction assembly 700 and the power supply assembly 300 are arranged adjacent to each other. Compared to other assemblies, the interaction assembly 700 is located closer to the power supply assembly 300; or no other functional assembly is arranged between the interaction assembly 700 and the power supply assembly 300; or the minimum distance between the interaction assembly 700 and the power supply assembly 300, compared to the size of the machine body 100 in the corresponding direction, has a ratio greater than 0 and at most 0.2.

[0101] It is understandable that the interaction module 700 is electrically connected to the power supply module 300, with the power supply module 300 supplying power to the interaction module 700. Both are located relatively close to each other, which simplifies the routing of the electrical connecting cables.

[0102] In the embodiment of the present application, the interaction assembly 700 can be positioned at the edge of the machine body 100, wherein the ratio of the minimum distance between the interaction assembly 700 and the edge of the machine body 100 to the size of the machine body 100 in the corresponding direction is greater than 0 and at most 0.1; or the interaction assembly 700 is arranged separately from the central area 110 of the machine body 100.

[0103] It should be noted that the interaction assembly comprises 700 different components, some of which may be mounted on the edge of the machine body 100. For example, the emergency stop switch is mounted on the edge of the machine body 100 to facilitate operation by the operator; with the screen positioned between the emergency stop switch and the power supply assembly 300.

[0104] The technical solution of the embodiment of the present application provides that human-machine interaction between the operator and the lawnmower takes place via an interaction assembly 700. The interaction assembly 700 and the power supply assembly 300 are arranged side by side, which facilitates the electrical connection and the routing of the cable bundles between the interaction assembly 700 and the power supply assembly 300; the interaction assembly 700 is located at the edge of the machine body 100 to make operation easier for the operator.

[0105] In some embodiments of the present application, with reference to Fig. 3, Fig. 4 and Fig. 5 the lawnmower further comprises an environmental perception assembly 800, wherein the environmental perception assembly 800 serves to detect features of the external environment; wherein the machine body 100 comprises a lateral end section 140, wherein the presetting axis L3 passes through the lateral end section 140, wherein the lateral end section 140 is located below the environmental perception assembly 800 when the handle 500 is lifted, so that the lawnmower leaves the driving surface M.

[0106] In the embodiment of the present application, the environmental perception assembly 800 serves to detect external environmental features in order to support the lawnmower's route planning and obstacle avoidance. The environmental perception assembly 800 can include cameras, distance sensors, touch sensors, and the like. In some examples, the environmental perception includes cameras. In some examples, the environmental perception assembly 800 is a recharging sensor.

[0107] In the embodiment of the present application, the lateral end section 140 of the machine body 100 refers to an end section that does not pass through the longitudinal center axis L1 and the transverse center axis L2, but rather through the presetting axis L3. In other words, the lateral end section 140 of the machine body 100 is located in one of the four areas subdivided by the longitudinal center axis L1 and the transverse center axis L2, and the presetting axis L3 passes through the lateral end section 140.

[0108] In the embodiment of the present application, the operator lifts the lawnmower by the handle 500. When the lawnmower is hanging down, the lateral end section 140 is located below the environmental perception assembly 800; in other words, the perpendicular distance of the lateral end section 140 to the driving surface M is less than the perpendicular distance of the environmental perception assembly 800 to the driving surface M.

[0109] The technical solution of the embodiment of the present application provides that the environmental perception assembly 800 can detect features of the external environment to serve as a reference for the movement of the lawnmower. When the handle 500 is lifted so that the lawnmower leaves the driving surface M, the lateral end section 140 is located below the environmental perception assembly 800. In other words, when the operator lifts the lawnmower by the handle 500 and the lawnmower naturally hangs downwards, the height of the lateral end section 140 is below the height of the environmental perception assembly 800, thus making the environmental perception assembly 800 less likely to collide with obstacles and thereby protecting it.

[0110] The lawnmower of the embodiment of the present application with reference to Fig. 1 and Fig. 6 The lawnmower comprises a machine body 100, a navigation assembly 600 and a handle 500, wherein the machine body 100 can move along the direction of travel X on the driving surface M; wherein the navigation assembly 600 is detachably connected to the machine body 100, wherein the navigation assembly 600 serves to acquire the navigation information of the machine body 100; wherein the handle 500 is connected to the machine body 100; wherein the handle 500 and the navigation assembly 600 are located at the same end section of the machine body 100.When viewed perpendicular to the driving surface M, the longitudinal center axis L1 and the transverse center axis L2 of the machine body 100 are perpendicular to each other, with the longitudinal center axis L1 running parallel to the direction of travel X; with the handle 500 being offset relative to the longitudinal center axis L1 and to the transverse center axis L2, with the presetting axis L3 of the handle 500 being inclined relative to the longitudinal center axis L1 so that it runs through the central area 110 of the machine body 100, with the presetting axis L3 of the handle 500 being perpendicular to the gripping surface 510 of the handle 500.

[0111] In the embodiment of the present application, the machine body 100 is the main structure of the lawn mower. The machine body 100 can comprise a housing and a drive assembly. The housing provides a mounting base and protection for the mowing assembly 200, the power supply assembly 300, the adjustment assembly 400, etc.; the drive assembly propels the lawn mower along the driving surface M, and the drive assembly can comprise drive wheels, a drive motor, a drive battery, etc.

[0112] In the embodiment of the present application, the navigation assembly 600 serves to acquire the positioning information of the machine body 100 so that the machine body 100 can plan its travel path based on this positioning information and perform highly precise mowing. The navigation assembly 600 can include a laser scanner, an ultrasonic localizer, a satellite localizer, and similar components. For example, the navigation assembly 600 includes a real-time kinematic (RTK) positioning assembly that enables highly precise positioning based on global satellite navigation systems.

[0113] In the embodiment of the present application, the detachable connection of the navigation assembly 600 to the machine body 100 can be a snap connection, a threaded connection, a fastening connection, or the like. For example, the navigation assembly 600 is attached to the machine body 100 by means of screws or other fasteners. The navigation assembly 600 can be mounted on the side of the machine body 100 facing away from the driving surface M to facilitate disassembly and assembly.

[0114] In the embodiment of the present application, the navigation assembly 600 and the handle 500 are located on the same end section of the machine body 100. In other words, the end section of the machine body 100 to which the navigation assembly 600 is attached is also equipped with the handle 500. However, the end section of the machine body 100 to which the handle 500 is attached can function without the navigation assembly 600.

[0115] In the embodiment of the present application, the connection of the handle 500 to the machine body 100 can be a detachable connection such as a plug connection, a threaded connection or a fastener connection, or a permanent connection such as welding, gluing, riveting or integral injection molding. In some embodiments, the handle 500 and the machine body 100 are integrally formed.

[0116] In the embodiment of the present application, the handle 500 is offset relative to the longitudinal center axis L1, that is, the longitudinal center axis L1 does not pass through the handle 500, but the handle 500 is located on one side of the longitudinal center axis L1; correspondingly, the handle 500 is offset relative to the transverse center axis L2, such that the transverse center axis L2 does not pass through the handle 500 and the handle 500 is located on one side of the transverse center axis L2. The technical solution of the embodiment of the present application provides that the handle 500 is offset both relative to the longitudinal center axis L1 and relative to the transverse center axis L2.

[0117] For example, when viewed perpendicular to the driving surface M, a planar coordinate system is established with the longitudinal center axis L1 and the transverse center axis L2. The longitudinal center axis L1 and the transverse center axis L2 divide this plane into four regions. The handle 500 can be located in one of the four regions without touching the longitudinal center axis L1 or the transverse center axis L2.

[0118] The technical solution of the embodiment of the present application provides that the machine body 100 serves as a mounting base for the navigation assembly 600 and the handle 500. The machine body 100 can also move along the direction of travel X on the driving surface M to enable mowing operations. The navigation assembly 600 serves to acquire the positioning information of the machine body 100 so that the lawnmower can perform route planning, and the handle 500 facilitates the operator's movement or operation of the lawnmower.

[0119] Based on this, the handle 500 is offset relative to the longitudinal center axis L1 of the machine body 100 and also relative to the transverse center axis L2; ​​in other words, the handle 500 is attached to the lateral front or rear of the machine body 100; the presetting axis L3 of the handle 500 is perpendicular to the grip surface 510 of the handle 500, and when the operator lifts the lawnmower by the handle 500, the direction of the interaction force between the operator and the lawnmower is parallel to the presetting axis L3, so that the operator can easily lift the lawnmower by the handle 500. The navigation assembly 600 and the handle 500 are arranged on the same end section of the machine body 100, so that when removing and attaching the navigation assembly 600, the operator can hold the handle 500 to stabilize the machine body 100, which facilitates the removal and attachment of the navigation assembly 600.

[0120] In contrast to technical solutions where the handle 500 is arranged on the side of the machine body 100, the handle 500 of the lawnmower described in the present application is arranged offset relative to the longitudinal center axis L1 and the transverse center axis L2. Furthermore, the handle 500 and the navigation assembly 600 are located on the same end section of the machine body 100, which makes it easier for the operator to attach and detach the navigation assembly 600 using the handle 500.

[0121] In some embodiments of the present application, with reference to Fig. 4 and Fig. 6 the machine body 100 comprises a first end section 120 and a second end section 130, wherein the first end section 120 and the second end section 130 are arranged one after the other in the direction of travel X; wherein at least one of the first end section 120 and of the second end section 130 is equipped with the handle 500.

[0122] In the embodiment of the present application, the first end section 120 can be the front end section of the machine body 100; in other words, as the machine body 100 travels forward along the track surface M, the first end section 120 is located in front of the second end section 130, and the first end section 120 passes the track surface M in front of the second end section 130; accordingly, the second end section 130 is the rear end section of the machine body 100.

[0123] In some examples, a handle 500 is attached to the first end section 120 of the machine body 100; in other examples, a handle 500 is attached to the second end section 130 of the machine body 100; in still other examples, handles 500 are attached to both the first end section 120 and the second end section 130 of the machine body 100. The handles 500 at the first end section 120 and at the second end section 130 can be located on the same or on opposite sides of the longitudinal center axis L1.

[0124] In the embodiment of the present application, the first end section 120 can be equipped with one or more handles 500; the second end section 130 can also be equipped with one or more handles 500. In some examples, one handle 500 is attached to the second end section 130 of the machine body 100; in other examples, two handles 500 are attached to the second end section 130 of the machine body 100; the two handles 500 being arranged symmetrically with respect to the longitudinal center axis L1.

[0125] In some examples, the navigation assembly 600 is attached to the first end section 120 of the machine body 100, the first end section 120 also being equipped with a handle 500; in other examples, the navigation assembly 600 is attached to the second end section 130 of the machine body 100, the second end section 130 also being equipped with a handle 500.

[0126] The technical solution of the embodiment of the present application provides that the handle 500 can be attached to the first end section 120 and / or to the second end section 130 of the machine body 100 in order to meet different application scenarios and operating requirements and to improve the adaptability of the lawnmower.

[0127] In some embodiments of the present application, with reference to Fig. 4 and Fig. 6 The longitudinal center axis L1 runs through the navigation assembly 600.

[0128] In the embodiment of the present application, the projections of the longitudinal center axis L1 and the navigation assembly 600 overlap when viewed perpendicular to the driving surface M. In other words, in the direction parallel to the transverse center axis L2, the navigation assembly 600 is arranged in the central part of the machine body 100.

[0129] In some embodiments, the end section of the machine body 100, to which the navigation assembly 600 is attached, is equipped with two handles 500. The navigation assembly 600 is located between the two handles 500, so that the operator can select the easier-to-handle handle 500 as needed.

[0130] The technical solution of the embodiment of the present application provides that the longitudinal center axis L1 runs through the navigation assembly 600; in other words, the navigation assembly 600 is mounted in the central region of the machine body 100. Whether the navigation assembly 600 is mounted on the machine body 100 or not has only a minor influence on the center of gravity distribution of the lawnmower. The installation of a navigation assembly 600 only slightly affects the driving and steering movements of the lawnmower, thus giving the lawnmower good drive consistency.

[0144] The technical solution of the embodiment of the present application provides that the projection of the machine body 100 covers the projection of the handle 500; in other words, the handle 500 is located within the boundary of the machine body 100. The arrangement of the handle 500 has only a minor influence on the overall size of the lawnmower, thereby making the structure of the lawnmower more compact and promoting its miniaturization.

[0145] In some embodiments of the present application, with reference to Fig. 1, Fig. 2 and Fig. 4 The handle 500 is provided with a through hole 520, wherein at least the inner wall of the through hole 520 forms the handle surface 510, wherein the presetting axis L3 runs through the central area of ​​the handle surface 510.

[0146] In the embodiment of the present application, the through-hole 520 on the handle 500 can be a hole that penetrates the handle 500, or the handle 500 is connected to the machine body 100, with a through-hole 520 being formed between the two.

[0147] In the embodiment of the present application, the shape of the through-hole 520 can be round, elliptical, square, triangular, trapezoidal, track-shaped, or similar. In one example, the through-hole 520 passes through the handle 500, wherein the through-hole 520 is a right-angled triangle and the handle 500 forms a gripping surface 510 on the side of the hypotenuse; in another example, the through-hole 520 is track-shaped, wherein the central part has a square structure and the two ends of the square structure are semicircular.

[0148] In the embodiment of the present application, the presetting axis L3 runs through the middle part of the grip surface 510; in other words, the presetting axis L3 runs through the middle area of ​​the handle 500, so that when the handle 500 is handled by the operator, the force is distributed more evenly.

[0149] The technical solution of the embodiment of the present application provides that the handle 500 is provided with a through-hole 520, the inner wall of the through-hole 520 serving as part of the gripping surface 510, so that the operator can grasp the handle 500 through the through-hole 520.

[0152] For example, the projection of the machine body 100 perpendicular to the driving surface M is approximately square, and there are two handles 500, the two handles 500 being located at two corners of the machine body 100 and arranged symmetrically to the longitudinal center axis L1.

[0153] The technical solution of the embodiment of the present application provides that at least two handles 500 are arranged symmetrically to the longitudinal center axis L1. On the one hand, this makes it easier for the operator to select different positions for lifting the lawnmower and thus increases ease of use; on the other hand, the multiple symmetrical handles 500 allow the operator to ensure a uniform application of force to the lawnmower.

[0154] In some embodiments of the present application, with reference to Fig. 4 and Fig. 5 the lawnmower further comprises an interaction assembly 700, wherein the interaction assembly 700 is provided for the human-machine interaction of the lawnmower; wherein the interaction assembly 700 and the power supply assembly 300 are arranged side by side; and / or the interaction assembly 700 is located at the edge of the machine body 100.

The interaction assembly 700 can be mounted on the side of the machine body 100 facing away from the driving surface M to facilitate operation.

[0156] In the embodiment of the present application, the interaction assembly 700 and the power supply assembly 300 are arranged adjacent to each other. Compared to other assemblies, the interaction assembly 700 is located closer to the power supply assembly 300; or no other functional assembly is arranged between the interaction assembly 700 and the power supply assembly 300; or the minimum distance between the interaction assembly 700 and the power supply assembly 300, compared to the size of the machine body 100 in the corresponding direction, has a ratio greater than 0 and at most 0.2.

[0157] It is understandable that the interaction module 700 is electrically connected to the power supply module 300, with the power supply module 300 supplying power to the interaction module 700. Both are located relatively close to each other, which simplifies the routing of the electrical connecting cables.

[0158] In the embodiment of the present application, the interaction assembly 700 can be positioned at the edge of the machine body 100, wherein the ratio of the minimum distance between the interaction assembly 700 and the edge of the machine body 100 to the size of the machine body 100 in the corresponding direction is greater than 0 and at most 0.1; or the interaction assembly 700 is arranged separately from the central area 110 of the machine body 100.

[0159] It should be noted that the interaction assembly comprises 700 different components, some of which may be mounted on the edge of the machine body 100. For example, the emergency stop switch is mounted on the edge of the machine body 100 to facilitate operation by the operator; with the screen positioned between the emergency stop switch and the power supply assembly 300.

[0160] The technical solution of the embodiment of the present application provides that human-machine interaction between the operator and the lawnmower takes place via an interaction assembly 700. The interaction assembly 700 and the power supply assembly 300 are arranged side by side, which facilitates the electrical connection and the routing of the cable bundles between the interaction assembly 700 and the power supply assembly 300; the interaction assembly 700 is located at the edge of the machine body 100 to make operation easier for the operator.

[0161] In some embodiments of the present application, with reference to Fig. 3, Fig. 4 and Fig.5 the lawnmower further comprises an environmental perception assembly 800, wherein the environmental perception assembly 800 serves to detect features of the external environment; wherein the machine body 100 comprises a lateral end section 140, wherein the presetting axis L3 passes through the lateral end section 140, wherein the lateral end section 140 is located below the environmental perception assembly 800 when the handle 500 is lifted, so that the lawnmower leaves the driving surface M.

[0162] In the embodiment of the present application, the environmental perception assembly 800 serves to detect external environmental features in order to support the lawnmower's route planning and obstacle avoidance. The environmental perception assembly 800 can include cameras, distance sensors, touch sensors, and the like. In some examples, the environmental perception includes cameras.

[0163] In the embodiment of the present application, the lateral end section 140 of the machine body 100 refers to an end section that does not pass through the longitudinal center axis L1 and the transverse center axis L2, but rather through the presetting axis L3. In other words, the lateral end section 140 of the machine body 100 is located in one of the four areas subdivided by the longitudinal center axis L1 and the transverse center axis L2, and the presetting axis L3 passes through the lateral end section 140.

[0164] In the embodiment of the present application, the operator lifts the lawnmower by the handle 500. When the lawnmower is hanging down, the lateral end section 140 is located below the environmental perception assembly 800; in other words, the perpendicular distance of the lateral end section 140 to the driving surface M is less than the perpendicular distance of the environmental perception assembly 800 to the driving surface M.

[0165] The technical solution of the embodiment of the present application provides that the environmental perception assembly 800 can detect features of the external environment to serve as a reference for the movement of the lawnmower. When the handle 500 is lifted so that the lawnmower leaves the driving surface M, the lateral end section 140 is located below the environmental perception assembly 800. In other words, when the operator lifts the lawnmower by the handle 500 and the lawnmower naturally hangs downwards, the height of the lateral end section 140 is below the height of the environmental perception assembly 800, thus making the environmental perception assembly 800 less likely to collide with obstacles and thereby protecting it.

[0166] In one possible embodiment of the present application, the lawnmower comprises a machine body 100, wherein the machine body 100 can move along the direction of travel X on the driving surface M. Attached to the machine body 100 are a mowing assembly 200, a power supply assembly 300, an adjustment assembly 400, a navigation assembly 600, an interaction assembly 700, an environment perception assembly 800, and a handle 500. The mowing assembly 200 is located on the side of the machine body 100 facing the driving surface M, the power supply assembly 300 is arranged inside the machine body 100, and the adjustment assembly 400 is located between the mowing assembly 200 and the machine body 100. The navigation assembly 600 is detachably attached to the side of the machine body 100 facing away from the driving surface M, and the navigation assembly 600 is located at the second end section 130 of the machine body 100.The interaction assembly 700 comprises a screen and an emergency stop switch. The emergency stop switch is mounted on the edge of the machine body 100 on the side facing away from the driving surface M. The screen is located between the emergency stop switch and the power supply assembly 300. The environmental perception assembly 800 comprises a camera mounted on the first end section 120 of the machine body 100. The handle 500 is located on the second end section 130 of the machine body 100 and at the corner of the machine body 100. In other words, the presetting axis L3 of the handle 500 corresponds to the diagonal of the machine body 100. When the operator lifts the lawnmower using the handle 500, the forces between the lawnmower and the operator act along the presetting axis L3, and the side end section 140 is located below the camera.
