Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] It should also be understood that the terminology used in this application specification is merely for describing specific realities within the scope of this application. It is important to understand that terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] like Figures 1 to 4 As shown, this application provides a self-moving cutting device, including a device body 10, a moving wheel assembly 20, and a cutting assembly 30. The moving wheel assembly 20 is used to drive the device body 10 to move, and the cutting assembly 30 is used to cut the object to be cut. The object to be cut includes, but is not limited to, grass on lawns, gardens, and paths; that is, the self-moving cutting device can be used to cut grass on lawns to ensure the aesthetics of the lawn.

[0023] In an optional embodiment, the moving wheel assembly 20 is disposed on the device body 10, and the cutting assembly 30 is disposed at the bottom of the device body 10. This allows the device body 10 to cut the grass on the lawn along a preset trajectory under the drive of the moving wheel assembly 20, thereby significantly reducing manual operation, saving time and effort, and truly freeing people from the labor of lawn maintenance. The moving wheel assembly 20 includes a front wheel assembly and a rear wheel assembly, which are spaced apart and symmetrically arranged on both sides of the device body 10. The cutting assembly 30 is disposed between the front wheel assembly and the rear wheel assembly.

[0024] In one alternative implementation, such as Figures 4 to 7 As shown, the main body 10 of the equipment includes a chassis 11 and a top shell 12. The chassis 11 and the top shell 12 enclose a first accommodating cavity 111 and a second accommodating cavity 112. The first accommodating cavity 111 and the second accommodating cavity 112 are separated from each other to achieve physical isolation of functional modules and also help to balance the weight of the main body 10 of the equipment. The weight of the functional modules can be reasonably distributed in the first accommodating cavity 111 and the second accommodating cavity 112. For example, the control unit or sensor processing unit is set in the first accommodating cavity 111, and the cutting assembly 30, power module or main drive board is set in the second accommodating cavity 112.

[0025] In an optional embodiment, the self-moving working device further includes a charging electrode and an infrared component, which are disposed at the rear end of the chassis 11 and electrically connected to the cable in the first receiving cavity 111. The cutting component 30 is disposed on the chassis 11 and electrically connected to the cable in the first receiving cavity 111.

[0026] In an optional embodiment, the outer side of the chassis 11 is provided with a receiving groove 113. The receiving groove 113 is provided with a first wire passing hole 114 and a second wire passing hole 115. The first wire passing hole 114 connects the receiving groove 113 and the first receiving cavity 111, and the second wire passing hole 115 connects the receiving groove 113 and the second receiving cavity 112. This allows the cable in the first receiving cavity 111 to pass through the first wire passing hole 114 into the receiving groove 113 and then enter the second receiving cavity 112 through the second wire passing hole 115, thereby completing the electrical connection between the second receiving cavity 112 and the functional module in the first receiving cavity 111. The second cable passage 115 is provided with a first sealing element 14. The first sealing element 14 is used to seal the gap between the cable and the second cable passage 115, preventing water and other liquids from entering the second accommodating cavity 112 through the gap between the cable and the second cable passage 115, causing the functional modules in the second accommodating cavity 112 to short circuit or some functions to fail, thereby improving the waterproof function of the functional modules in the second accommodating cavity 112.

[0027] After adopting the above technical solution, the cables in the first accommodating cavity 111 can enter the second accommodating cavity 112 through the accommodating slot 113, allowing for cable splicing, plugging, or fixing operations within the spacious and well-lit accommodating slot 113. This not only provides ample operating space and convenience but also enables centralized management and transfer of cables, transforming complex internal wiring problems into simple external operations. Operators can directly see and operate all cables and connectors within the accommodating slot 113 through its open opening, much like working in an open tray, thus greatly improving assembly efficiency and accuracy. Simultaneously, the accommodating slot 113 facilitates inspection and maintenance. During airtightness testing or future maintenance, operators can visually inspect the condition of the cables and the integrity of connector connections within the accommodating slot 113 without disassembling complex components. In order to ensure the sealing between the cable and the second cable passage hole 115 and prevent liquids such as water from entering the second accommodating cavity 112 through the gap between the cable and the second cable passage hole 115, this application provides a first sealing element 14 in the second cable passage hole 115 to replace the process of applying glue at the second cable passage hole 115, thereby improving production efficiency and facilitating automated assembly and testing.

[0028] In an alternative implementation, the receiving slot 113 can serve as a common, open wiring area or cable transfer station. All cables that need to be connected between the first receiving cavity 111 and the second receiving cavity 112 are first gathered here, and then distributed and connected. This solves the technical problem of how to efficiently and reliably route cables for self-moving equipment. Combined with the sealing of the second cable hole 115 by the first sealing element 14, it realizes the standardization of assembly process, operation visualization, and real-time inspection, greatly improving production efficiency and making it suitable for automated large-scale production.

[0029] For example, the cable in the first accommodating cavity 111 is inserted into the accommodating groove 113 through the first wire through hole 114, and the cable in the second accommodating cavity 112 is inserted into the accommodating groove 113 through the second wire through hole 115. Then, the two cables can be connected or bent within the accommodating groove 113. The operation space is large and very convenient. Meanwhile, to ensure the sealing of the second accommodating cavity 112 and prevent liquids such as water from entering the second accommodating cavity 112 through the gap between the cable and the second wire passage hole 115, this application provides a first sealing element 14 in the second wire passage hole 115 instead of relying on applying glue at the second wire passage hole 115. This results in more uniform quality and higher reliability, avoiding the problems of inconsistent amounts and uniformity caused by manual glue application, and ensuring good sealing quality consistency. Unlike glue, there is no need to wait for it to cure. After the first sealing element 14 is installed, an airtightness test can be performed immediately to promptly identify and address problems, ensuring the consistency of product quality. If the cable needs to be replaced, the first sealing element 14 can be replaced directly, which is much more convenient than cleaning up cured glue.

[0030] In an optional embodiment, the second accommodating cavity 112 and the first accommodating cavity 111 are arranged one after the other along the traveling direction of the device body 10. The cable in the second accommodating cavity 112 enters the second accommodating cavity 112 sequentially through the first cable passage hole 114, the accommodating groove 113 and the second cable passage hole 115. The cable path is neat and avoids random flying wires inside the device, which is beneficial for signal shielding and reducing electromagnetic interference. At the same time, the accommodating groove 113 can also realize centralized management and transfer of cables, transforming the complex internal wiring problem into a simple external operation.

[0031] It should be noted that "along the direction of travel of the device body" refers to the front-to-back direction of the device body as it moves, and the charging electrode and infrared component are located at the rear end of the device body.

[0032] In an optional embodiment, the receiving groove 113 has an opening, a first wire passage hole 114 is located on the bottom wall of the receiving groove 113 away from the opening, and a second wire passage hole 115 is located on one side wall of the receiving groove 113, so that the cable can enter the receiving groove 113 from below through the first wire passage hole 114 located on the bottom wall of the receiving groove 113, making the cable path the shortest, most direct, and neatest, avoiding messy flying wires. After the cable is connected or turned in the receiving groove 113, it enters the second receiving cavity 112 horizontally through the second wire passage hole 115 located on the side wall, fully considering the accessibility and convenience of manual operation during production assembly and later maintenance. The first sealing element 14 is used to seal the second wire hole 115 to ensure the sealing of the second accommodating cavity 112, so that the functional modules that need to be waterproof on the self-moving operating equipment can be accommodated in the second accommodating cavity 112. This achieves a reasonable allocation of sealing resources. While retaining the original structure, the modular design and mechanical seals eliminate the need to wait for curing, greatly improving reliability and assembly efficiency.

[0033] In one alternative implementation, such as Figures 2 to 4 As shown, a cover 13 is provided at the opening of the receiving groove 113. The cover 13 is used to separate the receiving groove 113 from the external space, so that the receiving groove 113 can be completely isolated from the harsh external environment, ensuring the sealing of the receiving groove 113. At the same time, it can also form a double sealing system with the first sealing member 14, improving the protection level of the self-moving operating equipment. The cover 13 is connected to the chassis 11 by screws or buckles, ensuring the stability of the cover 13 after connection.

[0034] In an optional embodiment, a sealing ring is provided at the opening of the receiving groove 113 or on the shield 13, so that when the shield 13 is fastened to the chassis 11, the sealing ring can be compressed and deformed, thereby forming a reliable sealing barrier.

[0035] In an alternative implementation, the shield 13 is quick-release connected to the chassis 11, allowing for rapid installation and removal of the shield 13 without the use of tools or with only very simple operations. This simplifies the maintenance process, reduces reliance on skilled technicians and specific tools, and saves valuable time.

[0036] For example, the shield 13 and the chassis 11 are connected by a rotating snap-fit. If the shield 13 has claws on its edge, it can be locked by rotating it at a certain angle after aligning it with the slot on the chassis 11. Alternatively, the shield 13 and the chassis 11 can be connected by magnetic adsorption to achieve a quick connection that can be aligned and fixed by adsorption. Alternatively, the shield 13 and the chassis 11 can be connected by a snap-fit ​​to achieve a locking effect by pressing.

[0037] In one alternative implementation, such as Figures 4 to 8 As shown, the first sealing member 14 includes a main body 141 and an annular stepped portion 142. The main body 141 extends axially along the second wire passage hole 115 and passes through the second wire passage hole 115 and elastically abuts against the inner wall of the second wire passage hole 115. The annular stepped portion 142 is disposed around the periphery of the main body 141 and extends radially toward the second wire passage hole 115. The annular stepped portion 142 abuts against the top of the second wire passage hole 115 so that after the main body 141 is inserted into the hole, the annular stepped portion 142 can fit tightly against the surface of the base 11 on the periphery of the second wire passage hole 115, thereby forming a solid sealing barrier at the end face of the opening of the second wire passage hole 115. When the main body 141 is pressed into the second wire passage hole 115, it will undergo compression deformation, thereby tightly embracing the inner wall of the wire passage hole, forming the first effective sealing barrier, preventing moisture and dust from entering from the gap between the hole wall and the seal, and together with the annular step part 142, it achieves a double bidirectional seal in the radial and axial directions, and its sealing effect is far superior to simple single-point sealing or applying glue.

[0038] In an optional embodiment, a hollow column 1151 protrudes from the second wire hole 115, and the hollow column 1151 communicates with the second wire hole 115. The annular step portion 142 abuts against the hollow column, ensuring that the seal can be installed correctly and flat, avoiding leakage caused by misalignment. At the same time, the hollow column 1151 can also provide a larger inner and outer wall surface area for the first seal 14, so that the first seal 14 can have a longer sealing contact path, making it more able to withstand the pulling force of the cable and the pressing force of the first seal 14, thereby improving the reliability of the seal.

[0039] In an alternative implementation, the receiving slot 113 is located in the area of ​​the chassis 11 near the rear end of the device body 10, so that the cable gathering and crossing point can be set at the rear end of the device body 10, thereby facilitating wiring and maintenance.

[0040] In an optional embodiment, the front end of the chassis 11 is provided with a third cable passage hole 116, which connects to the second accommodating cavity 112. A second sealing element 15 is provided inside the third cable passage hole 116 to seal the gap between the cable passing through the third cable passage hole 116 and the third cable passage hole 116, ensuring the sealing performance and reliability of the third cable passage hole 116, so that cables connected to other front-end components of the equipment body 10 can be sealed. The cable passing through the third cable passage hole 116 can be used for electrical connection to the hub motor of the front wheel assembly.

[0041] In an optional embodiment, both the first seal 14 and the second seal 15 are flexible components, which enable the first seal 14 and the second seal 15 to have good elasticity and resilience, thereby forming a tight fit with the cable inserted therein.
