[0027] 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.

[0028] 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.

[0029] See also Figures 1 to 3 In a first aspect, the utility model proposes an autonomous operating device 100.

[0030] The autonomous operation device 100 may include a first body 10 and a second body 20 (self-moving device). In the present application, the first body 10 is first described as an operation device and the second body 20 is described as a self-moving device.

[0031] The operating equipment is installed on the self-moving device so as to perform the operation in the predetermined operating area by relying on the movement of the self-moving device.

[0032] There may be multiple operating devices, each of which can realize its own independent operating function. For example, one operating device can realize the snow removal function, another operating device can realize the grass mowing function, another operating device can realize the leaf blowing function, and another operating device can realize the salt spreading function.

[0033] In the related art, the autonomous operation equipment 100 can replace manual work to complete tasks such as snow sweeping, grass cutting, salt spreading, and leaf blowing. In order to improve the flexibility of the autonomous operation equipment 100, adjacent parts are connected in a detachable manner, and the connection position is located relatively inside the equipment, making it difficult to ensure that the adjacent parts are connected stably. When the connection between adjacent parts is not stable enough, it will bring greater danger during the operation (for example: equipment damage, safety threats to people or pets).

[0034] Based on this, the applicant conducted in-depth research to solve the technical problem of how to determine whether the connection between adjacent components is stable, in order to form the technical solution of the present application.

[0035] 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.

[0036] The following is a detailed introduction to the crawler module structure in this application.

[0037] See also Figures 1 to 3 , the utility model proposes an autonomous operation device 100, comprising a first body 10 and a second body 20 which are detachably connected;

[0038] The first body 10 is provided with a Hall sensor 11 and a fastening member 12 that can be detachably connected to the second body 20, the fastening member 12 is provided with a magnetic member 13, and the fastening member 12 is rotatably arranged to have a locking position that can be connected to the second body 20 and an unlocking position that can be separated from the second body 20 during the rotation process;

[0039] When the buckle 12 is in the locked position, the magnetic member 13 is close to the sensing range of the Hall sensor 11 ; when the buckle 12 is in the unlocked position, the magnetic member 13 is far away from the sensing range of the Hall sensor 11 .

[0040] That is, when the buckle 12 is in the locked position, the buckle 12 is tightly connected to the second body 20, ensuring the connection stability of the device during operation. At this time, the magnetic member 13 is close to the sensing range of the Hall sensor 11, and the connection status is monitored in real time through the sensor.

[0041] When the buckle 12 is in the unlocked position, the buckle 12 is separated from the second body 20, allowing for convenient disassembly and maintenance operations. In this state, the connection between the buckle 12 and the second body 20 is released, providing a convenient and fast maintenance channel for the user. At this time, the magnetic member 13 is away from the sensing range of the Hall sensor 11, triggering sensor feedback to ensure that the system records the unlocked state.

[0042] The user can easily separate or replace the parts of the device and perform necessary maintenance work. Once the maintenance is completed, the user only needs to rotate the fastener 12 to the locked position and reconnect the first body 10 and the second body 20 to put them in the locked position. In the locked position, the fastener 12 is firmly reconnected to the second body 20 to ensure the connection stability of the device during normal operation. This design makes the maintenance of the device more convenient and helps to improve the overall operating efficiency and reliability of the device.

[0043] By integrating the Hall sensor 11 and the rotatable fastener 12, this embodiment solves the problem that the detachable connection position is inside the device and realizes intelligent connection status monitoring. This improved design effectively improves the connection stability of the autonomous operation device 100, reduces the risk of equipment damage, and ensures safety during the operation.

[0044] In some embodiments, the buckling member 12 is rotatably connected to the first body 10 via a rotating shaft, and the magnetic member 13 is located on the buckling member 12 at a position away from the rotating shaft.

[0045] The buckle 12 is rotatably connected to the first body 10 via a rotating shaft, and the design of the magnetic member 13 enables it to have a larger rotation range during the rotation process. Specifically, the rotating shaft of the buckle 12 is tightly connected to the first body 10, so that it can rotate around the rotating shaft. The magnetic member 13 is cleverly designed on the buckle 12, away from the position of the rotating shaft, and during the rotation process, the magnetic member 13 can switch with the sensing range of the Hall sensor 11 in a larger range.

[0046] When the buckle 12 is in the locked position, the sensor monitors in real time that the magnetic part 13 is close to the sensing range of the Hall sensor 11, ensuring the firmness of the connection. When in the unlocked position, the buckle 12 rotates more around the axis, so that the magnetic part 13 is away from the sensing range of the Hall sensor 11, triggering the sensor feedback, indicating that the device is in the unlocked state.

[0047] This design not only has advantages in terms of connection firmness, but also makes it easier for the device to enter the unlocked state by increasing the rotation range of the fastener 12, thereby improving the convenience of disassembly and maintenance. Expanding the rotation range helps users to operate the autonomous working device 100 more flexibly, so that the device can better adapt to various operating requirements in different working scenarios.

[0048] In some embodiments, the buckling member 12 includes a connecting portion 121 rotatably connected to the rotating shaft, a buckling portion 122 for buckling, and a swinging portion 123 connected between the buckling portion 122 and the connecting portion 121 , and the magnetic member 13 is located at the buckling portion 122 .

[0049] The connecting portion 121 is tightly connected to the first body 10 via a rotating shaft, ensuring that the fastening member 12 can rotate around its axis. The connecting portion 121 is designed to provide a stable mechanical support so as to maintain the stability of the structure during the rotation process.

[0050] The buckle portion 122 is the main functional part of the buckle 12, which is used to connect the first body 10 and the second body 20. When in the locked position, the buckle portion 122 ensures that the buckle 12 is tightly connected to the second body 20 to ensure the connection stability of the device. The shape and structure of the buckle portion 122 are designed to provide a firm connection and allow flexible swinging when unlocking.

[0051] The swinging portion 123 is connected between the buckling portion 122 and the connecting portion 121, allowing the buckling portion 122 to adjust its position during the swinging process. The existence of the swinging portion 123 allows the buckling portion 122 to swing in a wider range when unlocked, increasing the rotation range of the buckling member 12. This swinging structure allows the magnetic member 13 to be further away from the sensing range of the Hall sensor 11 when in the unlocked position, thereby improving the reliability of the device in the unlocked state.

[0052] The magnetic member 13 is cleverly designed on the buckle part 122 to ensure that the relative position of the magnetic member 13 and the Hall sensor 11 can be switched during the rotation of the buckle part 12, thereby realizing the conversion between the locked position and the unlocked position. This design makes the device more flexible and convenient during operation and maintenance, while improving the reliability and stability of the connection.

[0053] In some embodiments, the buckling portion 122 is formed with a buckling surface, and the magnetic member 13 is located away from the buckling surface.

[0054] The buckle portion 122 is designed to form a flat buckle surface for connecting with the corresponding part of the second body 20. The shape and size of the buckle surface are adapted to the specific requirements of the device, ensuring a firm connection in the locked position and improving the stability of the device.

[0055] Furthermore, the magnetic member 13 is precisely arranged at a position where the buckle portion 122 is away from the buckle surface. This arrangement ensures that when in the locked position, the magnetic member 13 is close to the sensing range of the Hall sensor 11, maintaining the firmness of the connection. At the same time, when in the unlocked position, the magnetic member 13 is away from the buckle surface, triggering sensor feedback, indicating that the device is in the unlocked state, which is convenient for disassembly and maintenance.

[0056] In other words, this design structure enables the device to have a stable connection surface when in the locked position, providing reliable support and stability. In the unlocked position, since the magnetic member 13 is away from the snap-fit ​​surface, users can more easily perform disassembly and maintenance operations. Overall, this structure is designed to optimize the connection stability of the device while ensuring flexibility and ease of operation.

[0057] In some embodiments, the snap fit member 12 is provided with a mounting hole, the magnetic member 13 is provided with a through hole corresponding to the mounting hole, the snap fit member 12 and the magnetic member 13 are connected via an assembly member, and the assembly member is passed through the mounting hole and the through hole.

[0058] In order to further strengthen the connection between the buckle 122 and the magnetic member 13, the buckle 12 is designed to have one or more mounting holes. At the same time, the magnetic member 13 is configured to have a through hole corresponding to the mounting hole of the buckle 12. The two are connected by an assembly part, wherein the assembly part passes through the mounting hole of the buckle 12 and the through hole of the magnetic member 13, so that the buckle 12 and the magnetic member 13 are tightly combined.

[0059] One or more mounting holes are provided on the fastening member 12, and these holes are used to receive the connecting assembly parts. The position and number of the mounting holes can be flexibly adjusted according to the design requirements.

[0060] The magnetic member 13 is provided with a through hole corresponding to the mounting hole of the buckle member 12 , so as to ensure that the assembly part can pass through the through hole, so that the magnetic member 13 is connected to the buckle member 12 .

[0061] The assembly part, as a connecting medium, is passed through the mounting hole of the fastening member 12 and the through hole of the magnetic member 13, tightly combining the fastening member 12 and the magnetic member 13. This connection method not only increases the firmness of the connection, but also helps to ensure that the fastening member 12 and the magnetic member 13 work together during the rotation process.

[0062] This design achieves a more reliable connection between the fastener 12 and the magnetic member 13, improving the stability of the overall connection system. At the same time, the introduction of the assembly makes the combination of the fastener 12 and the magnetic member 13 more flexible and more adaptable, which helps to meet the needs of different working scenarios.

[0063] In some embodiments, the mounting hole includes a countersunk section and a connecting section connected to each other, the magnetic member 13 is at least partially accommodated in the countersunk section, and the assembly member is connected to the connecting section.

[0064] The mounting hole is divided into two parts, a countersunk section and a connecting section. The countersunk section is the starting part of the mounting hole, usually a section embedded in the buckle 12. The connecting section is another part connected to the countersunk section, usually presenting a shape extending out of the buckle 12.

[0065] The countersunk section is an area for accommodating the magnetic member 13. Such a design allows the magnetic member 13 to be at least partially embedded in the buckle member 12, which helps to ensure a more secure connection between the magnetic member 13 and the buckle member 12.

[0066] The assembly part is connected to the connecting section of the mounting hole. The connecting section is usually located after the countersunk section and can be an extension of the fastening member 12. The assembly part connects the fastening member 12 and the magnetic member 13 together through the connecting section to ensure their coordinated movement.

[0067] The advantage of this design is that the connection between the snap-fitting part 12, the magnetic part 13 and the assembly part is further consolidated through a more complex mounting hole structure, thereby improving the stability and reliability of the system. At the same time, the accommodation of the magnetic part 13 in the countersunk section makes the entire connection more compact, which helps to reduce the prominence of the components.

[0068] In some embodiments, the assembly part is a screw and a screw head of the screw is received in the through hole.

[0069] Screws are selected as the assembly parts for connecting the fastening member 12 and the magnetic member 13. Screws are a common and easily available connection element, and their structure is simple and effective.

[0070] The screw head of the screw is cleverly accommodated in the through hole of the magnetic member 13. This design ensures a tight connection between the screw and the magnetic member 13, and improves the firmness of the connection.

[0071] By using screws as assembly parts and accommodating the screw heads in the through holes of the magnetic parts 13, a reliable connection between the fastening parts 12 and the magnetic parts 13 is achieved. This assembly method is simple and effective, and provides a feasible solution to ensure a stable connection between the fastening parts 12 and the magnetic parts 13, thereby increasing the reliability of the connection system of the entire autonomous working equipment 100.

[0072] In some embodiments, the first body 10 includes a shell 14 , an outer surface of the shell 14 is formed with a mounting groove 141 , and the Hall sensor 11 is disposed in the mounting groove 141 .

[0073] The outer structure of the first body 10 is composed of a housing 14, which provides protection and support for the internal components.

[0074] The outer surface of the housing 14 is formed with a mounting groove 141, which provides a suitable position for mounting internal equipment. The mounting groove 141 is generally designed to accommodate and accommodate related components.

[0075] The Hall sensor 11 is mounted on the housing 14 in the mounting groove 141. This position selection helps to mount the Hall sensor 11 on the device more stably and can monitor the state of the fastening member 12 more accurately.

[0076] Through this design, the Hall sensor 11 is embedded in the housing 14 of the first body 10, which not only helps to reduce the risk of external damage to the sensor, but also enables the sensor to better adapt to the appearance design of the device. At the same time, the presence of the mounting groove 141 provides a convenient mounting structure, so that related components can be effectively integrated into the autonomous operation device 100.

[0077] In some embodiments, a wire outlet groove 142 communicating with the mounting groove 141 is further formed on the outer surface of the housing 14 .

[0078] The outer surface of the housing 14 is provided with wire outlet grooves 142, which are connected to the mounting grooves 141. The design of the wire outlet grooves 142 helps to manage and guide the wires, cables or other connecting wires related to the device, making them more neat and orderly.

[0079] The outlet groove 142 is connected to the installation groove 141, which means that the cables or connecting wires can be directly guided from the installation groove 141 to the outlet groove 142. This design simplifies the wiring and management of the cables and helps to optimize the overall structure.

[0080] The presence of the cable outlet slot 142 helps to hide the cables and improve the neatness of the device appearance. This is particularly important for the autonomous working device 100 because it helps to reduce the risk of damage to external components and improves the aesthetics of the device.

[0081] By forming a cable outlet groove 142 on the outer surface of the shell 14 that is connected to the installation groove 141, this design effectively solves the problem of cable wiring and management, and provides a neater and more elegant appearance for the autonomous working device 100.

[0082] In some embodiments, the first body 10 is one or more of a snow sweeping body, a grass mowing body, a salt spreading body, a leaf blowing body and a rolling brush body, and the second body 20 is a self-moving body.

[0083] The first body 10 can be selected based on specific application requirements, for example, a snow sweeping body for snow clearing, a mowing body for lawn mowing, a salt spreading body for road salting, a leaf blowing body for leaf sweeping, or a roller brush body for ground sweeping. Such diverse selections allow the autonomous working device 100 to flexibly adapt to different working scenarios.

[0084] The second body 20 is a self-moving body, which is responsible for the movement and navigation of the device, so that the autonomous working device 100 can autonomously navigate in the working area, thereby improving the intelligence and working efficiency of the device.

[0085] By modularizing the main bodies with different functions, it is easier to customize and assemble the equipment. Users can select and combine different main bodies according to actual needs to meet specific operation requirements.

[0086] This modular design makes the autonomous working device 100 more flexible in dealing with different tasks, while giving full play to the advantages of the self-moving body in navigation and coordination. Overall, this structural design improves the applicability and versatility of the autonomous working device 100.

[0087] In some embodiments, a controller is further included in the second body 20 , and the controller can control the actions of the first body 10 and / or the second body 20 according to the sensing signal of the Hall sensor 11 .

[0088] The controller is placed inside the second body 20, usually located in the control center of the device, and is responsible for coordinating and managing the operation of the entire autonomous operation system.

[0089] The controller can receive and interpret the sensing signals from the Hall sensor 11. Based on these signals, the controller can adjust and control the actions of the first body 10 (e.g., snow sweeping body, grass cutting body, etc.) and / or the second body 20 (self-moving body) in real time.

[0090] By dynamically responding to the sensing signal of the Hall sensor 11, the controller can adjust the movement, direction or other key operations of the device according to the actual working requirements. This real-time feedback mechanism helps the device to adapt to different working environments more intelligently.

[0091] This design scheme realizes intelligent control of the autonomous operation equipment 100 by introducing a controller. The Hall sensor 11 provides key perception information, and the controller makes corresponding decisions based on this information, so that the equipment can complete various operation tasks efficiently and flexibly. Overall, this system structure improves the adaptability and intelligence of the autonomous operation equipment 100.
