[0029] 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.

[0030] 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.

[0031] In the related art, an automatic lawn mower is used for mowing in a garden. The automatic lawn mower generally includes a detachable self-moving device and a mowing mechanism 100, which are connected by a connecting mechanism so that the mowing mechanism 100 can have more flexible mobility to adapt to different terrains. Since the connecting mechanism is exposed to the outside, it is easily damaged by external factors (sewage, weeds, dust, etc.), resulting in poor mobility of the mowing mechanism 100, which affects its mowing work.

[0032] Based on this, the applicant conducted in-depth research to solve the technical problem of how to ensure that the connection mechanism between the self-moving device and the mowing mechanism 100 is not damaged by external factors, so as to form the technical solution of the present application.

[0033] 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.

[0034] The structure of the mowing mechanism 100 in the present application is described in detail below.

[0035] See also Figure 1 and Figure 2 The utility model provides a mowing mechanism 100, comprising a connecting body 10 and a mowing body 20 connected by a connecting assembly 30, wherein the mowing body 20 can move relative to the connecting body 10;

[0036] The mowing mechanism 100 further includes a protective cover 40 , and the protective cover 40 is disposed on the outer side of the connecting assembly 30 .

[0037] The connecting body 10 may be a part of an automatic lawn mower, and its structure is configured to stably install or fix the lawn mower body 20 , while providing necessary power and control signal transmission to the lawn mower body 20 .

[0038] The mowing body 20 may include a set of mowing blades, which are driven to rotate by a motor to complete the mowing work. The mowing body 20 is designed to be adjustable relative to the connecting body 10 to adapt to different heights and inclinations of the ground.

[0039] The connection assembly 30 may be a key component between the connection body 10 and the mowing body 20, allowing the mowing body 20 to make necessary position and direction adjustments relative to the connection body 10 during mowing. The assembly may include, but is not limited to, a hinge device, a sliding guide rail, or an elastic support structure to provide a certain range of mobility and adaptability.

[0040] The provision of the protective cover 40 is one of the core features of this embodiment. It covers the outside of the connection assembly 30 and is used to protect the connection assembly 30 from external environmental factors (such as sewage, weeds, dust, etc.). The protective cover 40 is made of corrosion-resistant, high-strength materials, such as high-density polyethylene (HDPE) or silicone, to ensure that the connection assembly 30 remains intact even under harsh external conditions. The protective cover 40 is designed to be easy to install and remove, so that the user can clean or replace it when necessary.

[0041] Through the above structural design, the mowing mechanism 100 of this embodiment not only improves the mowing efficiency and the ability to adapt to different terrains, but also significantly increases the durability and reliability of the equipment, and reduces maintenance costs and time. The design of the mowing mechanism 100 fully considers the actual needs of users in daily use and provides an efficient and economical mowing solution.

[0042] This embodiment describes a specific mowing mechanism 100 design, which is intended to enhance the overall performance and durability of the device by providing additional protection measures. Although specific embodiments are described in detail, it should be understood that the scope of protection of the utility model is not limited thereto. Various modifications and changes can be made to the details without departing from the spirit and scope of the utility model.

[0043] In some embodiments, the protective cover 40 is cylindrical and has two ends connected to the connecting body 10 and the mowing body 20 respectively.

[0044] The protective cover 40 is designed in a cylindrical shape, and this cylindrical shape optimizes the protection range and efficiency of the connection component 30. The protective cover 40 is connected to the connection body 10 and the mowing body 20 at both ends, forming a closed protection space, which can not only minimize the direct contact between external substances (such as weed fragments, soil, moisture and other substances that may cause wear or corrosion) and the connection component 30, but also reduce physical collision damage to the connection component 30 during the mowing process.

[0045] In some embodiments, at least a portion of the protective cover 40 is a deformable structure, and the protective cover 40 is configured to be deformed when the mowing body 20 moves.

[0046] The protective cover 40 at least partially comprises a deformable structure, so that it can be deformed under the action of external force without being damaged. This deformation capability allows the protective cover 40 to provide dynamic adaptability when the mowing body 20 moves up and down or sideways to adapt to different terrains, thereby ensuring that the connecting assembly 30 is always in a protected state.

[0047] In order to achieve this feature, the protective cover 40 is made of a composite material with high elasticity and good durability, such as silicone, elastic polymer or other high-performance elastic materials. These materials can not only withstand repeated deformation without cracking or breaking, but also return to their original shape when no external force is applied.

[0048] In some embodiments, the protective cover 40 includes:

[0049] Two connecting members 41, a first connecting member 41 is connected to the connecting body 10, and a second connecting member 41 is connected to the mowing body 20;

[0050] A cover member 42 connected between the first connecting member 41 and the second connecting member 41 to cover the outside of the connecting assembly 30;

[0051] The cover member 42 is a deformable flexible member.

[0052] Specifically, the protective cover 40 includes two key connecting parts 41, which are respectively connected to the two main parts of the lawn mower, the connecting body 10 and the mowing body 20. The first connecting part 41 is fixed to the connecting body 10, and the second connecting part 41 is fixed to the mowing body 20. Such a design allows the protective cover 40 to span and protect those exposed and easily damaged connecting components 30, while also providing the necessary freedom of movement for the mowing body 20.

[0053] Furthermore, the cover 42 is connected to the two connecting members 41, and its core design lies in its deformable characteristics. This flexible cover 42 is connected between the first and second connecting members 41, forming a protective layer covering the outside of the connecting assembly 30. The cover 42 is made of highly flexible materials, such as elastic polymers, soft silicone or other highly elastic materials, which can maintain shape and strength while allowing the cover 42 to deform accordingly according to the movement of the mowing body 20.

[0054] By designing the cover member 42 as a deformable flexible member, the present embodiment significantly improves the adaptability of the protective cover 40. This design enables the cover member 42 to naturally expand or contract when the mowing body 20 moves, turns, or adjusts the mowing height, ensuring that all important connecting components 30 can continue to be protected, even in more complex mowing tasks.

[0055] In addition, the flexible design of the cover 42 also means that it can absorb a certain degree of impact force, reducing the damage that external objects (such as stones, branches, etc.) may cause to the connection assembly 30. At the same time, it can also prevent moisture, dust and impurities from entering the connection part, thereby reducing maintenance requirements and extending the service life of the equipment.

[0056] In some embodiments, the connecting member 41 includes two overlapping connecting portions, and an end portion of the cover member 42 is pressed between the two connecting portions.

[0057] Specifically, the connector 41 adopts a design scheme of two overlapping connecting parts, which means that the two connecting parts overlap each other in structure to form a stable connection point. This design not only improves the structural strength of the entire connector 41, but also provides a more stable and tight connection interface between the cover 42 and the connector 41.

[0058] The end of the cover member 42 is cleverly designed to be pressed between the two overlapping connection parts. This pressing method utilizes the principle of physical clamping to ensure that the connection between the cover member 42 and the connection member 41 is both stable and reliable. The design of the pressing part takes into account the necessary mechanical strength to resist the tensile, twisting or compressive forces that may be generated by the action of the mowing body 20.

[0059] By pressing the end of the cover 42 between the two connecting parts, not only the force generated by movement or external force acting on the cover 42 is effectively dispersed, but also the cover 42 is prevented from falling off under violent movements. This design optimizes the mechanical distribution and improves the stability and durability of the entire protective cover 40 structure.

[0060] In addition, this overlapping and pressing design also simplifies the assembly process. During installation, it is only necessary to place the end of the cover member 42 between the two connecting parts, and then ensure their stable connection through appropriate pressing means (such as bolting, bonding or other mechanical locking methods). This design is not only convenient for production and assembly, but also convenient for future maintenance and replacement.

[0061] In some embodiments, the cover member 42 is a waterproof cloth member, or the cover member 42 is a corrugated pipe member.

[0062] When the cover 42 is a waterproof cloth, the cover 42 is made of a waterproof cloth, which has excellent waterproof properties and can effectively prevent water and moisture from penetrating into the connecting parts and the inside of the mowing mechanism 100. The waterproof cloth is usually made of specially treated polymer fibers, and has a coating or film on its surface to form an effective waterproof barrier.

[0063] When the cover 42 is a bellows, the design of the bellows not only provides excellent protection, but also has good durability and adaptability. It can effectively absorb impact and vibration, reduce the risk of damage to the connecting parts, and maintain a good connection between the connecting parts and the mowing body 20.

[0064] In some embodiments, the mowing body 20 includes a first shell 21, the first shell 21 is formed with a first inner cavity and a first opening communicating with the first inner cavity, and the end of the protective cover 40 is sealed and connected to the periphery of the first opening;

[0065] And / or, the connection body 10 includes a second shell 11, the second shell 11 is formed with a second inner cavity and a second opening communicating with the second inner cavity, and the end of the protective cover 40 is sealed and connected to the periphery of the second opening.

[0066] The first housing 21 is formed with a first inner cavity which is connected to the first opening. This design allows the mowing mechanism 100 inside the mowing body 20 to operate normally and be connected to the external environment through the first opening, so as to facilitate the operation and maintenance of the mower.

[0067] The end of the protective cover 40 is sealed with the periphery of the first opening, which can effectively prevent external impurities from entering the interior of the mowing body 20. Through the sealed connection, the protective cover 40 and the first shell 21 form a tightly closed space, providing a higher level of protection for the connecting assembly 30.

[0068] The second housing 11 is also formed with a second inner cavity, and the inner cavity is connected to the second opening. The design of the second opening allows the connection body 10 to exchange necessary gas or liquid with the external environment to ensure the normal operation of the device.

[0069] The end of the protective cover 40 and the periphery of the second opening are also sealed to ensure that the interior of the connection body 10 is not affected by the external environment. This sealed connection not only protects the connection components from external factors such as sewage, weeds, and dust, but also helps to maintain a stable working environment inside the connection body 10.

[0070] By achieving a sealed connection between the mowing body 20 and the connecting body 10, these embodiments provide a more complete and comprehensive protection mechanism, ensuring the safe operation of the connecting assembly 30 in various environments. This design is suitable for various types of automatic mowers, improving the reliability and service life of the equipment.

[0071] In summary, these embodiments achieve all-round protection of the connection assembly 30 by realizing a sealed connection with the end of the protective cover 40 in the shell structure of the mowing body 20 and the connecting body 10. This sealed connection design not only improves the service life and reliability of the mower, but also helps to reduce maintenance costs and improve work efficiency.

[0072] In some embodiments, the connection assembly 30 includes a rotating shaft, which is mounted on the connection body 10 and rotatably connected to the mowing body 20 to allow the mowing body 20 to rotate relative to the connection body 10 .

[0073] The rotating shaft is mounted on the connecting body 10, usually at the center of the lawn mower or other appropriate position to ensure that the mowing body 20 can rotate around it. This mounting method forms a fixed rotating connection point between the mowing body 20 and the connecting body 10, thereby realizing the rotation of the mowing body 20 relative to the connecting body 10.

[0074] The rotating shaft is rotatably connected to the mowing body 20, which means that the rotating shaft is one of the key components for the rotation of the mowing body 20. Through the design of the rotating shaft, the mowing body 20 can perform a smooth rotational motion with the support of the connecting body 10, thereby realizing the mowing operation of the mower in different directions and angles.

[0075] The existence of the rotating shaft allows the mowing body 20 to rotate relative to the connecting body 10, which enables the mower to adapt to different terrains and mowing requirements. For example, when turning or encountering obstacles, the mowing body 20 can adjust its direction and position by rotating the rotating shaft to ensure the continuity and consistency of the mowing effect.

[0076] The design of the rotating shaft increases the adaptability of the mower, enabling it to easily handle terrains of different shapes and heights. The rotation of the mowing body 20 enables the mower to be flexibly operated in complex terrains such as slopes, slopes, narrow passages, etc., thereby improving mowing efficiency and coverage.

[0077] In these embodiments, the rotating shaft, as an important component of the connecting assembly 30, realizes the rotation connection between the mowing body 20 and the connecting body 10, thereby providing greater flexibility and adaptability for the mower. This design enables the mower to easily cope with various mowing tasks, improving its efficiency and reliability in practical applications.

[0078] In some embodiments, the connection assembly 30 further includes a tension spring, the two ends of which are respectively connected to the connection body 10 and the mowing body 20 , and the tension spring applies a tension force to the mowing body 20 in a direction from bottom to top.

[0079] 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.
