[0026] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] In the related art, most lawn mowers are not designed with special consideration for working performance on slopes or inclined surfaces, which leads to significant limitations and challenges when climbing slopes. Traditional lawn mowers are often designed with a relatively fixed height and a flat bottom structure, which may perform well on flat ground, but will encounter difficulties on slopes, resulting in poor mowing results.

[0029] Based on this, the applicant conducted in-depth research to solve the technical problem that the mowing mechanism would encounter difficulties in climbing a slope, so as to form the technical solution of the present application.

[0030] It should be noted that, in the present application specification, when a component is considered to be "disposed on" another component, it may be connected to or directly disposed on another component, or there may be a central component at the same time; when a component is considered to be "connected to" another component, it may be directly connected to another component or there may be a central component at the same time.

[0031] The following is a detailed introduction to the crawler module structure in this application.

[0032] Reference Figure 1 and 2 In a first aspect, the utility model provides a mowing mechanism 100, comprising:

[0033] housing 10; and

[0034] The enclosure assembly 20 is disposed at the bottom of the shell 10 to enclose the shell 10 to form a mowing chamber. From the front to the rear, the height of the enclosure assembly 20 from the ground gradually decreases.

[0035] The housing 10 is an outer shell constituting the main body of the lawn mower and is made of a light and high-strength material, such as high-strength plastic or light alloy, to reduce the overall weight and facilitate the operation and movement of the machine on a slope.

[0036] The enclosure assembly 20 is mounted at the bottom of the housing 10. The key to the design of the enclosure assembly 20 is that its height gradually decreases from the front to the back. This unique design allows the front end of the mower to be lower when climbing a slope, which is beneficial to the forward movement of the mower and the effective contact between the mowing blade and the lawn. It also has a guiding effect and reduces the risk to the operator when the rear end is raised.

[0037] It is understandable that the mowing mechanism 100 may further include a mowing blade, which is located inside the enclosure assembly 20 and encloses a mowing chamber together with the bottom of the housing 10. The configuration and shape of the blade are optimized to improve mowing efficiency and adapt to different lawn conditions.

[0038] Through the above design, the mowing mechanism 100 of the utility model can significantly improve the mowing performance and safety on slopes and inclined ground, while also optimizing the user's operating experience. This design allows the mower to more effectively adapt to the challenges of different terrains, improve mowing efficiency, reduce labor intensity, and enhance the applicability and flexibility of the machine.

[0039] In some embodiments, the enclosure assembly 20 includes an enclosure body 21, and the enclosure body 21 includes a first enclosure section 211 located at the front side;

[0040] In the direction from front to rear, the height of the first enclosure section 211 from the ground gradually decreases.

[0041] Among them, in this design, the detailed design of the enclosure assembly 20 further optimizes the adaptability and efficiency of the mowing mechanism 100 on different terrains, especially when dealing with slopes and inclined ground. The following is a further description of this embodiment:

[0042] Detailed structure of the enclosure assembly 20: The enclosure body 21, the core part of the enclosure assembly 20, provides physical isolation between the machine and the grass, protecting the internal mowing blades from damage and preventing grass clippings and stones from splashing out, ensuring the safety of operation. The key to the design of the enclosure body 21 is the adjustability of its height and inclination to meet the needs of different mowing environments.

[0043] The first enclosure section 211 is located at the front side of the enclosure body 21. The characteristic of this part is that its height from the ground gradually decreases from the front to the back. The advantages of this design include:

[0044] Improved adaptability: As the height of the first enclosure section 211 from the ground gradually decreases, the lawn mower can transition more smoothly when encountering a slope, reducing the possibility of the front end lifting, thereby maintaining better stability and mowing efficiency on the slope.

[0045] Increased Efficiency: Gradually decreasing fence height helps the mowing blades get closer to the ground for a more even and precise mowing result, even on uneven terrain.

[0046] Reduced damage: This design also reduces the damage caused by the machine to the grass, especially in areas with large slopes or complex terrain, and can handle ground vegetation more carefully and gently.

[0047] In some embodiments, a front reinforcement is provided on the front side of the first enclosure section 211 , and the front reinforcement is a metal member.

[0048] The design of introducing the front reinforcement further improves the durability and applicability of the mowing mechanism 100, especially the performance when dealing with complex terrain. The following is an in-depth description of the design:

[0049] The design and function of the front reinforcement, among which the design features are: the front reinforcement is located at the front side of the first enclosure section 211 and is made of metal material. This design not only enhances the structural strength of the enclosure assembly 20, but also improves the ability to resist impact and wear, especially when facing obstacles such as stones and tree roots, it can effectively protect the front end of the lawn mower.

[0050] Among them, material selection: metal is selected as the material of the front reinforcement, such as steel or aluminum alloy, because these materials have high strength, good wear resistance and impact resistance. The metal reinforcement is precisely processed and treated to ensure that it is strong and durable without excessively increasing the overall weight, maintaining the control flexibility and convenience of the lawn mower.

[0051] The front reinforcement provides an extra layer of protection for the mower, reducing the risk of damage when working on difficult terrain such as slopes, uneven or rocky areas.

[0052] By reducing direct impact and wear, the front reinforcement effectively extends the life of the mower and reduces long-term maintenance and repair costs.

[0053] The addition of reinforcements can provide a smoother transition, especially when facing hard obstacles, improving the operator experience and ensuring a smoother and more efficient mowing process.

[0054] The front reinforcement is closely integrated with the design of the first enclosure section 211 to ensure the harmony of the overall appearance and function. In addition, the shape, size and installation position of the reinforcement are carefully designed to optimize the mowing efficiency and the operating performance of the machine.

[0055] In some embodiments, the height of the front reinforcement from the ground gradually decreases in the direction from front to rear.

[0056] By setting the height of the front reinforcement to gradually decrease from the ground, it can be ensured that when the mower encounters a slope or uneven ground, the front end can adapt to terrain changes more smoothly, reducing the risk of bumps or damage to the machine caused by uneven terrain.

[0057] This design helps maintain the cutting unit's relative position to the ground, allowing for a more even and precise mowing even on sloped surfaces, improving overall mowing efficiency.

[0058] The gradually decreasing ground clearance helps the mower maintain a lower center of gravity on sloping ground, increasing the machine's stability on slopes and reducing the risk of tipping over.

[0059] As the height of the front reinforcement from the ground is gradually lowered, even when encountering uneven or hard obstacles, the impact force can be dispersed more effectively, reducing damage and wear to the machine itself and its mowing system.

[0060] In some embodiments, the enclosure body 21 further includes a second enclosure segment 212 and a third enclosure segment 213 connected to the left and right sides of the first enclosure segment 211 respectively;

[0061] In the direction from front to back, the height of the second enclosure section 212 and the height of the third enclosure section 213 from the ground gradually decrease.

[0062] The gradually decreasing heights of the second enclosure section 212 and the third enclosure section 213 from the ground enable the mowing blades to be closer to the ground on a slope or uneven ground, thereby ensuring a more uniform and thorough mowing effect.

[0063] This design not only improves the mowing effect of the lawn mower, but also enhances its stability on the slope. The gradually decreasing ground clearance of the second enclosure section 212 and the third enclosure section 213 helps to reduce the swaying and tilting of the machine during operation, thereby improving the safety and comfort of the operator.

[0064] This design also reduces damage to the lawn by bringing the mowing blade closer to the ground. Especially when working on slopes, the lowered fence height can reduce the pressure and friction of the mower on the lawn, helping to keep the lawn healthy and beautiful.

[0065] In some embodiments, the height of the second enclosure section 212 from the ground gradually decreases from left to right, and / or the height of the third enclosure section 213 from the ground gradually decreases from right to left.

[0066] In this design, the heights of the second enclosure segment 212 and the third enclosure segment 213 from the ground not only gradually decrease from the front to the rear, but also change in the lateral direction. Specifically, the height of the second enclosure segment 212 from the ground gradually decreases from the left to the right, while the height of the third enclosure segment 213 from the ground gradually decreases from the right to the left.

[0067] The design of gradually decreasing lateral ground clearance allows the mower to better adapt to irregular terrain, such as steep borders or asymmetrical terrain, ensuring consistent and thorough mowing results.

[0068] By gradually reducing the height of the fence section from the ground in the lateral direction, the relative height of the mowing blade at different positions can be kept consistent, thereby improving mowing efficiency and consistency.

[0069] In some embodiments, a side reinforcement is provided at the bottom of the second enclosure section 212 and / or the bottom of the third enclosure section 213, and the side reinforcement is a metal member.

[0070] In this design, in addition to connecting the second enclosure section 212 and the third enclosure section 213 on the left and right sides of the enclosure body 21 respectively, side reinforcements are also provided at their bottoms, and the front reinforcement is still made of metal material.

[0071] The side reinforcement is located at the bottom of the enclosure section to provide additional support and stability for the enclosure body 21, especially in the case of uneven terrain or steep slopes, which helps prevent the enclosure body 21 from deforming or twisting.

[0072] By providing the side reinforcements, the stress concentration at the bottom of the enclosure section can be reduced, the service life of the enclosure body 21 can be extended, and the cost of maintenance and repair can be reduced.

[0073] The addition of the side reinforcements can enhance the ability of the enclosure body 21 to resist external impacts and reduce the risk of damage to the machine during mowing.

[0074] In some embodiments, the ground clearance of the side reinforcement gradually decreases from the outside to the inside.

[0075] In this design, in addition to providing side reinforcements to enhance the stability and durability of the enclosure body 21, a design is also considered in which the height of the side reinforcements from the ground is gradually reduced. This gradually reduced design further optimizes the adaptability of the lawn mower in different terrains and environments.

[0076] The side reinforcements are gradually lowered from the ground so that the mower can better adapt to terrains of different heights, and can operate more stably, especially when dealing with large ground height differences.

[0077] The gradually decreasing height of the side reinforcement from the ground helps to maintain the structural stability of the lawn mower, especially when dealing with uneven or rugged ground, and can reduce the shaking and deformation of the enclosure body 21.

[0078] By gradually lowering the ground clearance of the side reinforcement, it is possible to ensure that the relative height of the mowing blades at different positions remains consistent, thereby improving mowing efficiency and consistency.

[0079] In some embodiments, the first enclosure section 211 is formed with a notch, and the enclosure assembly 20 further includes a comb tooth bar 214, wherein the comb tooth bar 214 is installed in the notch, and the height of the comb tooth bar 214 from the ground gradually decreases in the direction from front to rear.

[0080] In this design, a gap is formed in the first enclosure section 211, and a comb bar 214 is installed in the gap. This design allows the enclosure assembly 20 to more effectively collect and guide grass in the lawn when mowing, and also allows the height of the comb bar 214 from the ground to gradually decrease in the front-to-back direction to adapt to different terrains and lawn heights.

[0081] By forming a notch in the first enclosure section 211 and installing the comb teeth 214, the lawn mower can more effectively collect and guide grass in the lawn, thereby improving mowing efficiency and consistency.

[0082] The design of the comb teeth 214 gradually decreasing in height from the ground enables the lawn mower to better adapt to terrains and lawns of different heights, and can operate more stably, especially when dealing with large ground height differences.

[0083] The installation of the comb teeth bar 214 can reduce the situation where the blade directly contacts the ground and hard objects, which helps to protect the lawn from damage and keep the lawn healthy and beautiful.

[0084] In a second aspect, the present invention further provides an automatic lawn mower, comprising a self-moving device and the above-mentioned mowing mechanism 100, wherein the mowing mechanism 100 is installed on the self-moving device.
