[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0024] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0025] As mentioned above, when the lawn mowers on the market are in motion, the positional relationship between the cutter assembly and the main body is fixed, so it is difficult for the cutter to better fit the ground. Therefore, in an environment with complex terrain, the mowing effect is poor and it is easy to have adverse conditions such as jamming.

[0026] At least one embodiment of the present disclosure provides a lawn mower, which includes a body, a tool assembly and an elastic member; the body has a tool connection end, and includes a first tool fixing structure located at the tool connection end, wherein the first tool fixing structure includes a first elastic member fixing portion, and the tool assembly includes a second tool fixing structure for fixing the tool, wherein the second tool fixing structure includes a second elastic member fixing portion, and the elastic member is located between the first elastic member fixing portion and the second elastic member fixing portion to elastically connect the first tool fixing structure and the second tool fixing structure.

[0027] In the lawn mower provided in the embodiment of the present disclosure, by providing an elastic member, the cutter assembly can have a certain degree of floating relative to the body of the machine, so as to adapt to uneven roads, improve the mowing effect, and make the lawn mower run smoothly.

[0028] The lawn mower provided by the embodiment of the present disclosure is described below through several specific embodiments.

[0029] At least one embodiment of the present disclosure provides a lawn mower. Figure 1 The structure diagram of the lawn mower is shown. Figure 2 A schematic cross-sectional view of the lawn mower at the elastic member is shown. Figure 3 FIG. 2 shows a front view of the lawn mower. Figure 1-Figure 3 As shown, the lawn mower includes a body 10, a cutter assembly 20, an elastic member 30 and other structures.

[0030] like Figure 1-Figure 3 As shown, the fuselage body 10 has a tool connection end 11, and the front end of the fuselage body 10 when traveling is shown as the tool connection end 11. The fuselage body 10 includes a first tool fixing structure 12 located at the tool connection end 11, which is used to connect with the tool assembly 20. The first tool fixing structure 12 includes a first elastic member fixing portion 13. The tool assembly 20 includes a second tool fixing structure 21, which is used to fix a tool 20A. The tool 20A is used to realize the mowing function. The second tool fixing structure 21 includes a second elastic member fixing portion 22.

[0031] like Figure 2 As shown, the elastic member 30 is located between the first elastic member fixing portion 13 and the second elastic member fixing portion 22 to elastically connect the first tool fixing structure 12 and the second tool fixing structure 21 .

[0032] In the embodiments of the present disclosure, “elastic connection” of two structures means that the two structures can be relatively offset in position via an elastic member therebetween, so that the positions and states of the two structures are not completely relatively fixed.

[0033] Therefore, when the lawn mower is traveling on an uneven road surface, the cutter 20A of the cutter assembly 20 may encounter an obstacle (such as a bump on the road surface, etc.). At this time, through the elastic action of the elastic member 30, the cutter assembly 20 can have a certain elastic floating relative to the body 10, thereby helping the cutter 20A to pass through the obstacle smoothly and achieve a closer mowing effect along the surface of the obstacle.

[0034] For example, in some embodiments, Figure 2 As shown, the fuselage body 10 may include a lifting / flipping assembly 40, and the first tool fixing structure 12 is slidably set on the lifting / flipping assembly 40, so that it can be lifted or flipped by the lifting / flipping assembly 40, thereby changing the position or state of the tool assembly 20 to achieve a mowing mode or a tool cleaning mode, etc.

[0035] For example, in some embodiments, the body 10 may further include a housing and a driving device (for driving the lawn mower to move), a power supply device (for supplying power to the lawn mower), and a control device (such as a controller) located inside the housing, and the body 10 may also be connected to a motion device (such as a crawler) to drive the lawn mower to move. The embodiments of the present disclosure do not limit the specific structure of the body 10.

[0036] For example, in some embodiments, Figure 2 and Figure 3 As shown, the first tool fixing structure 12 includes a tool bracket 14 connected to the fuselage body 10, and the second tool fixing structure 21 includes a tool fixing plate 23. The tool bracket 14 and the tool fixing plate 23 are at least partially arranged opposite to each other. The portion of the tool bracket 14 that is arranged opposite to the tool fixing plate 23 is the first elastic member fixing portion 13, and the portion of the tool fixing plate 23 that is arranged opposite to the tool bracket 14 is the second elastic member fixing portion 22.

[0037] For example, in some embodiments, Figure 2 and Figure 3 As shown, the first elastic member fixing portion 13 and the second elastic member fixing portion 22 are plate-shaped, and the elastic member 30 is clamped between the first elastic member fixing portion 13 and the second elastic member fixing portion 22, thereby realizing an elastic connection between the first elastic member fixing portion 13 and the second elastic member fixing portion 22 to allow the tool of the tool assembly 20 to have a certain elastic floating relative to the fuselage body 10.

[0038] For example, in some embodiments, Figure 2 As shown, the lawn mower may further include a first fixing member 31, which passes through the first elastic member fixing portion 13, the elastic member 30 and the second elastic member fixing portion 22 in sequence to fix the elastic member 30 to the first elastic member fixing portion 13 and the second elastic member fixing portion 22 to prevent the elastic member 30 from moving in series.

[0039] For example, in some embodiments, the first fixing member 31 can be a fixing screw. In this case, there can be an elastic gap between the fixing screw and the first elastic member fixing portion 13 (for example, an elastic pad, such as a rubber member, is provided), and there can be an elastic gap between the fixing screw and the second elastic member fixing portion 22 (for example, an elastic pad, such as a rubber member, is provided) to further provide elastic force.

[0040] For example, in some embodiments, Figure 2 and Figure 3 As shown, the number of the elastic member 30 may be one, and in this case, the elastic member 30 is located in the middle of the first elastic member fixing portion 13 and the second elastic member fixing portion 22. For example, in other embodiments, the number of the elastic members 30 may also be multiple, and in this case, the multiple elastic members may be evenly arranged between the first elastic member fixing portion 13 and the second elastic member fixing portion 22. The embodiments of the present disclosure do not specifically limit the number of the elastic members 30.

[0041] For example, in some embodiments, the material of the elastic member 30 includes an elastic material, such as rubber, and in this case, the elastic member 30 can be formed in the form of a rubber block. For example, the length, width, height and other dimensions of the rubber block can be determined according to factors such as the size and weight of the tool 20A and the size of the first elastic member fixing portion 13 and the second elastic member fixing portion 22, so as to achieve elastic connection within a certain range.

[0042] For example, in some embodiments, Figure 2 As shown, the cross-sections of the tool holder 14 and the tool fixing plate 23 are both L-shaped as a whole. The tool holder 14 and the tool fixing plate 23 respectively include horizontally arranged plate surfaces. The horizontally arranged plate surfaces of the tool holder 14 and the tool fixing plate 23 are at least partially arranged opposite to each other to form the first elastic member fixing portion 13 and the second elastic member fixing portion 22.

[0043] For example, Figure 4 FIG. 2 shows a structural schematic diagram of another lawn mower provided by at least one embodiment of the present disclosure. Figure 4 As shown, in other embodiments, one of the first elastic member fixing portion and the second elastic member fixing portion includes a fixing rod 41, and the other includes at least one fixing cylinder 42 opposite to the fixing rod 41, the elastic member 30 at least partially surrounds (e.g. completely surrounds) the fixing rod 41, and the fixing cylinder 42 at least partially surrounds (e.g. completely surrounds) the elastic member 30. Thus, an elastic connection is achieved between the fixing rod 41 and the fixing cylinder 42.

[0044] For example, Figure 5 and Figure 6 for Figure 4 Schematic diagram of the cross section of the lawn mower at different positions, such as Figure 5 and Figure 6As shown, in this embodiment, the tool support 14 connected to the fuselage body 10 includes a fixing cylinder 42 as a first elastic member fixing portion, the tool fixing plate 23 of the tool assembly 20 includes a fixing rod 41 as a second elastic member fixing portion, and the elastic member 30 is sandwiched between the fixing rod 41 and the fixing cylinder 42. For example, the elastic member 30 completely surrounds the fixing rod 41, and the fixing cylinder 42 completely surrounds the elastic member 30, thereby realizing the elastic connection between the fixing rod 41 and the fixing cylinder 42.

[0045] For example, in some embodiments, Figure 6 As shown, at least one fixed cylinder 42 includes two fixed cylinders 42, and the two fixed cylinders 42 are symmetrically and spaced apart. Thus, a balanced elastic force is provided on both sides of the lawn mower to achieve a stable floating of the cutter relative to the fuselage body 10.

[0046] For example, in the above embodiments, Figure 3 and Figure 5 As shown, the lawn mower may further include a damping member 51 and a second fixing member 52; the damping member 51 is elastically arranged between the tool bracket 14 and the tool fixing plate 23, and the second fixing member 52 passes through the tool bracket 14, the damping member 51 and the tool fixing plate 23 in sequence to fix the damping member 51 to the tool bracket 14 and the tool fixing plate 23.

[0047] In the embodiment of the present disclosure, the damping member 51 can further provide an elastic supporting force between the tool support 14 and the tool fixing plate 23 , and make the floating of the tool 20A relative to the fuselage body 10 more stable and smooth.

[0048] For example, in some embodiments, the damping member 51 may include a damping spring, and the second fixing member 52 may include a fixing screw, in which case the damping spring 51 is sleeved on the fixing screw 52. Alternatively, in other embodiments, the damping member 51 may include a rubber block having a different elasticity from the elastic member 30, for example, a rubber block having a smaller elasticity than the elastic member 30, in which case the second fixing member 52 may sequentially pass through the tool support 14, the rubber block, and the tool fixing plate 23 to fix the damping member 51 to the tool support 14 and the tool fixing plate 23.

[0049] For example, in some embodiments, the number of damping members 51 can be multiple, and two are shown in the figure, and they are symmetrically arranged. The damping members 51 can increase the damping feeling or elastic force when the tool 20A floats. For example, the damping members 51 can be symmetrically distributed on both sides of the first fixing member 31 along the center line of the fuselage body.

[0050] For example, when the left and right sides of the tool 20A are subjected to uneven force, the damping member 51 on one side will be compressed, and the tool 20A will float left and right. When the tool 20A is subjected to uneven force front and back, such as encountering an obstacle and being lifted up, the damping member 51 will also be compressed, which will appear as the tool 20A rising. When the tool 20A is suspended in the air or the front is downhill, due to the elastic force of the damping member 51 and its own gravity, the tool 20A will automatically droop, so that the tool 20A can achieve different states according to different environments and road conditions.

[0051] For example, Figure 7 FIG. 2 shows a structural schematic diagram of another lawn mower provided by at least one embodiment of the present disclosure, such as Figure 7 As shown, in this embodiment, the tool support 14 connected to the fuselage body 10 includes a fixing rod 41 as a first elastic member fixing portion, the tool fixing plate 23 of the tool assembly 20 includes a fixing cylinder 42 as a second elastic member fixing portion, and the elastic member 30 is sandwiched between the fixing rod 41 and the fixing cylinder 42. For example, the elastic member 30 completely surrounds the fixing rod 41, and the fixing cylinder 42 completely surrounds the elastic member 30, thereby realizing the elastic connection between the fixing rod 41 and the fixing cylinder 42.

[0052] For example, Figure 8 Shows Figure 7 A schematic cross-sectional view of a lawn mower at an elastic member in some embodiments, such as Figure 8 As shown, at least one fixing cylinder 42 includes a fixing cylinder 42 which is arranged at the center of the fixing rod 41 to provide a balanced elastic force on both sides of the lawn mower to achieve the floating of the cutter relative to the body 10 .

[0053] For example, Figure 7 and Figure 8 The embodiment may also include structures such as a damping member 51 and a second fixing member 52, and adopt a basically similar arrangement, which will not be repeated here.

[0054] In summary, in the embodiments of the present disclosure, the elastic member 30 and the damping member 51 can serve as a terrain-fitting (cutter floating) structure of the lawn mower. By arranging the elastic member 30 (such as a rubber member / rubber block) in a very small space, the floating of the tool 20A can be achieved, and the tool 20A can be adapted to the different heights of the terrain on the left and right sides, as well as the different front and rear heights of the tool 20A. At the same time, there is a certain damping sense and elasticity, so that the tool 20A can adapt to the undulations of the ground more evenly and better fit the ground.

[0055] For example, when the lawn mower is traveling on a flat road, the relative position of the tool bracket and the main body of the machine body is constant; when there is a steep obstacle in front of the lawn mower, the tool 20A will be passively lifted up, and at this time, the elastic member 30 and the damping member 51 can be adaptively compressed to adapt to the obstacle; or, when the ground in front of the lawn mower is undulating, the tool 20A can have a slight pitch through the elasticity of the elastic member 30 and the damping member 51 to adapt to the ground; or, when the left and right heights of the ground in front of the lawn mower are different, the tool 20A can be twisted through the elastic member 30 and the damping member 51 to make the left and right sides of the tool assembly 20 different in height to adapt to the ground.
