[0007] In some embodiments, the guide sleeve has a groove at one end close to the interior of the shell, and the hook lock assembly also includes a fixed gasket, which has an inserting portion inserted in the groove to limit the movement of the guide sleeve in the axial direction of the connecting hole.

[0008] In some embodiments, a second movable gap is provided between the fixing gasket and the guide sleeve, and the first movable gap is not equal to the second movable gap.

[0009] In some embodiments, the first active gap is larger than the second active gap.

[0031] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings, i.e., embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] 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.

[0033] The utility model proposes an autonomous operation device, including a working module 100 and a self-moving device 200. The working module 100 can be easily installed on the self-moving device 200, which can be specifically embodied as a snow sweeping, grass cutting, and leaf blowing module. The self-moving device 200 generates a predetermined operation path based on the operation area set by the user. The self-moving device 200 can be a mobile carrier such as a crawler vehicle or a wheeled vehicle that can have an installation position for the working module 100. The self-moving device 200 and the working module 100 are combined to form an autonomous operation device to complete environmental cleaning, patrol and monitoring work in areas such as urban roads, parks, factories, and family courtyards.

[0034] In the related art, the self-moving device 200 and the working module 100 of the autonomous operating equipment are often connected by a hook lock assembly 20. However, the following problems usually exist in the connection: on the one hand, during the production and assembly process, an assembly error occurs in either the self-moving device 200 or the working module 100, which may cause the hook lock assembly 20 to be misaligned, and the self-moving device 200 and the working module 100 cannot be successfully combined; on the other hand, after the autonomous operating equipment has been working for a long time, the hook lock assembly 20 is deformed, which also makes it difficult to combine the self-moving device 200 and the working module 100.

[0035] Based on this, the applicant conducted in-depth research to solve the technical problem of difficulty in combining the mobile device 200 and the working module 100 when assembly errors occur or the hook body is deformed, so as to form the technical solution of the present application.

[0036] The following describes in detail the structure of the autonomous operation equipment in this application.

[0037] Please refer to Figures 1 to 3 The utility model provides an autonomous operation device, comprising:

[0038] The self-moving device 200 is provided with a first hook body 201; the working module 100 has a shell 10 with a connecting hole 11, a hook lock assembly 20 is installed in the shell 10, and the hook lock assembly 20 has a guide sleeve 21 installed in the connecting hole 11, and a first movable gap 22 is provided between the outer wall of the guide sleeve 21 and the inner wall of the connecting hole 11, so as to allow the guide sleeve 21 to be able to adaptively move relative to the inner wall of the connecting hole 11 in the radial direction of the connecting hole 11 under the action of external force, and the inner wall of the guide sleeve 21 can be adapted to the outer contour of the first hook body 201, so as to allow at least a part of the first hook body 201 to pass through the inner wall of the guide sleeve 21 into the interior of the shell 10 and be detachably connected with the hook lock assembly 20.

[0039] The working module 100 has a housing 10 for covering the internal structure of the working module 100. The housing 10 is provided with a connecting hole 11 at a position connected to the self-moving device 200, and a hook lock assembly 20 is installed inside the housing 10. The self-moving device 200 has a first hook body 201, which enters the housing 10 through the connecting hole 11 and is detachably connected to the hook lock assembly 20.

[0040] The housing 10 may be made of metal or plastic, and is usually thin. In this embodiment, the guide sleeve 21 is inserted into the connecting hole 11 of the housing 10. When the working module 100 is connected to the mobile device 200, the first hook 201 is inserted into the housing 10 along the inner wall of the guide sleeve 21. The guide sleeve 21 has the following two functions. First, the housing 10 is thin, resulting in low connection stability between the housing 10 and the first hook 201. The guide sleeve 21 has a certain guide length, which can compensate for the thinness of the housing 10, making the connection between the first hook 201 and the guide sleeve 21 more stable. On the other hand, the inner wall of the guide sleeve 21 is designed to be compatible with the outer contour of the first hook 201. After the first hook 201 penetrates from the outside of the housing 10 to the inside of the housing 10 and reaches the best connection position with the hook lock assembly 20, it can limit the further penetration of the first hook 201 to prevent excessive insertion and failure to connect with the hook lock assembly 20.

[0041] There is a first movable gap 22 between the outer wall of the guide sleeve 21 and the inner wall of the connecting hole 11 of the present application, and the gap enables the guide sleeve 21 to adaptively move in the radial direction of the connecting hole 11 under the action of external force. This design provides an effective solution to the inability to connect normally with the hook lock assembly 20 due to assembly errors and component deformation, which is further explained below:

[0042] When the self-moving device 200 and the functional module are assembled, if there is an assembly error in the installation position, resulting in the first hook body 201 being unable to be smoothly connected to the hook lock assembly 20, since the guide sleeve 21 has a first movable gap 22, it can move slightly in the radial direction of the connecting hole 11, so that the first hook body 201 can be smoothly inserted and connected to the hook lock assembly 20. This slight adjustment can compensate for the assembly error, reduce the rework and adjustment caused by it, and thus improve the assembly efficiency. In addition, if the parts involved in the connection are deformed, for example, due to changes in the working environment temperature or long-term use, this may also make it difficult to combine the self-moving device 200 and the working module 100. In this case, the guide sleeve 21 can fine-tune its position to adapt to the deformed parts through the adaptive activity of the first movable gap 22, so as to connect with the hook lock assembly 20, reducing the cost of maintenance and replacement.

[0043] Please refer to Figures 7 and 8 In some embodiments, the guide sleeve 21 has a groove 211 at one end close to the inside of the housing 10, and the hook lock assembly 20 further includes a fixing gasket 23, and the fixing gasket 23 has an inserting portion 231 inserted in the groove 211 to limit the movement of the guide sleeve 21 in the axial direction of the communicating hole 11. Specifically, the portion of the guide sleeve 21 passing through the communicating hole 11 has an annular groove 211, and the inserting portion 231 of the fixing gasket 23 is open and can be inserted into the annular groove 211 from the side of the portion of the guide sleeve 21 passing through the communicating hole 11.

[0044] During assembly, the guide sleeve 21 passes through the connecting hole 11 from the outside of the shell 10, and one end of the guide sleeve 21 with the groove 211 enters the inside of the shell 10. The fixing gasket 23 is inserted into the groove 211 of the guide sleeve 21 through the open plug-in portion 231 from the inside of the shell 10. The fixing gasket 23 is fixedly connected to the shell 10, thereby limiting the movement of the guide sleeve 21 in the axial direction of the connecting hole 11, that is, the guide sleeve 21 cannot fall out of the connecting hole 11 under the action of the fixing gasket 23.

[0045] Please refer to Figure 5 and Figure 6 In some embodiments, there is a second movable gap 24 between the fixed gasket 23 and the guide sleeve 21 , and the first movable gap 22 is not equal to the second movable gap 24 .

[0046] The gap between the outer wall of the groove 211 of the guide sleeve 21 and the inner wall of the plug-in portion 231 of the fixed gasket 23 is the second active gap 24. Since the first active gap 22 and the second active gap 24 are not equal, the first active gap 22 and the second active gap 24 jointly participate in regulating the adaptive activity of the guide sleeve 21. The amplitude of the adaptive activity of the guide sleeve 21 depends on the smaller value of the first active gap 22 and the second active gap 24.

[0047] In some embodiments, the first active gap 22 is larger than the second active gap 24 .

[0048] When the first movable gap 22 is larger than the second movable gap 24, the adaptive movement will not exceed the range of movement allowed by the first movable gap 22, that is, the range of movement allowed by the first movable gap 22 is the upper limit, and the second movable gap 24 further limits the range of adaptive movement of the guide sleeve 21. During production assembly or when the user uses it, the second movable gap 24 can be adjusted by replacing the fixing gasket 23, thereby adjusting the range of movement of the guide sleeve 21 relative to the inner wall of the connecting hole 11.

[0049] Please refer to Figure 6 In this way, the screw 25 fixes the fixing gasket 23 to the housing 10. The screw 25 passes through the housing 10 and partially protrudes from the housing 10. When the guide sleeve 21 rotates along the axis, the inner wall of the limiting hole 212 of the guide sleeve 21 interferes with the screw 25, limiting the further rotation of the guide sleeve 21. This limiting effect is beneficial to improving the stability of the guide sleeve 21 and reducing the damage that may be caused by unstable rotation.

[0050] Please refer to Figure 6 In some embodiments, a third movable gap 26 is provided between the portion of the screw 25 protruding from the housing 10 and the limiting hole 212 .

[0051] That is to say, the diameter of the limiting hole 212 is larger than the diameter of the screw 25, and the third movable gap 26 between the portion of the screw 25 protruding from the housing 10 and the limiting hole 212 affects the range of rotation of the guide sleeve 21 around its axis. On the basis that the first movable gap 22 provides the guide sleeve 21 with adaptive movement in the radial direction of the communicating hole 11, the third movable gap 26 also provides the guide sleeve 21 with a range of rotation in the axial direction, so that the guide sleeve 21 can be more flexibly connected to the hook lock assembly 20, thereby improving the assembly efficiency.

[0052] Combined with reference Figure 8 and Fig. 9 In some embodiments, the guide sleeve 21 further has a threaded hole 213 for fixedly connecting with the housing 10. The guide sleeve 21 is bolted to the housing 10 through the threaded hole 213. At this time, the guide sleeve 21 is fixedly connected to the housing 10, that is, it cannot be adaptively moved relative to the inner wall of the connecting hole 11. The threaded hole 213 provides another installation method for the guide sleeve 21. The production assembly personnel and the user can choose one according to the actual production conditions or usage conditions to meet different needs.

[0053] Please refer to Fig. 9 The guide sleeve 21 has a guide portion 214 for guiding the first hook body 201 into the interior of the housing 10 .

[0054] The position where the guide sleeve 21 first contacts the first hook 201 has a guide portion 214, which can be rounded or chamfered to reduce friction and loss when the first hook 201 enters the guide sleeve 21, thereby extending the service life of the components. Any structure that is conducive to guiding the first hook 201 to penetrate deeper into the housing 10 is within the scope of protection of this application and is not limited here.

[0055] Please refer to Figure 3 The hook lock assembly 20 includes a second hook body 27 located inside the housing 10 . The second hook body 27 can rotate in the plane of the housing 10 where it is located under the action of an external force to achieve connection or separation with the first hook body 201 .

[0056] In this embodiment, the hook lock assembly 20 has a connecting rod mechanism, and under the action of external force, the connecting rod mechanism drives the second hook body 27 to rotate in the plane of the housing 10 where it is located. This design makes the connection and separation process between the self-moving device 200 and the functional module faster and more convenient. When the first hook body 201 of the self-moving device 200 passes through the housing 10 of the functional module through the guide sleeve 21, under the action of external force, the second hook body 27 in the housing 10 rotates in its plane until the second hook body 27 contacts the first hook body 201 and completes the connection. When separation is required, the second hook body 27 rotates in the opposite direction under the action of external force, thereby disengaging from the first hook body 201 to complete the separation from the self-moving device 200. This design ensures that the disassembly and assembly process between the self-moving device 200 and the functional module is quick and convenient, which is beneficial to the operating efficiency and work efficiency of the operator. In addition, the hook lock assembly 20 is located inside the housing 10, which can not only avoid exposure to the hook lock assembly 20 from being hit and worn, but also is not easily affected by the external environment, such as unhooking caused by collision. This prolongs the service life of the hook lock, helps reduce maintenance and replacement costs, and helps improve the stability of the entire connection mechanism.
