Abstract
Description
Technical Field
[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, and in particular relates to a sliding multi-point locking canopy. Background Technology
[0002] Drone field operations often require frequent battery or payload changes, necessitating operation by opening the canopy. For medium-sized drones or those carrying specialized equipment with large canopies, multiple locking points are typically used around the canopy to ensure reliable connection between the canopy and the fuselage. These locking points generally employ quick-release latches, quick-release locks, and hand-tightened screws for ease of operation. The problem is that the use of multiple independently operated quick-release devices in these technologies leads to a significant decrease in ease of operation when the number of canopy locking points is large. Summary of the Invention
[0003] In view of this, the present invention aims to at least partially solve one of the related technical problems.
[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0005] A sliding multi-point locking hatch includes a hatch body, a first locking assembly, a second locking assembly, a front locking structure, and a rear locking structure.
[0006] The first locking assembly and the second locking assembly are symmetrically arranged on the left and right sides of the hatch body, and the first locking assembly and the second locking assembly have the same structure.
[0007] The front locking structure is located at the front end of the hatch body, and the rear locking structure is located at the rear end of the hatch body.
[0008] The first locking assembly, the second locking assembly, the front locking structure, and the rear locking structure are all used to achieve a detachable connection between the hatch body and the fuselage.
[0009] The first locking assembly includes multiple sliding locking structures, which are arranged on the side of the hatch body. When the hatch body slides longitudinally along the fuselage, the locking hooks of the multiple sliding locking structures move synchronously and enter the corresponding locking holes on the fuselage at the same time, thereby making the hatch body reach the locked state.
[0010] Furthermore, the first locking assembly includes a locking hook structure and a locking hole structure. The top of the locking hook structure is fixedly connected to the hatch body, and the bottom of the locking hook structure is detachably connected to the locking hole structure. The locking hole structure is disposed on the body.
[0011] Furthermore, the locking hook structure includes a support block and a first locking hook, the top of the first locking hook is fixedly connected to the support block, the support block is fixedly connected to the outer wall of the hatch body, and the bottom of the first locking hook is detachably connected to the locking hole structure.
[0012] Furthermore, the lock hole structure includes a guide cone hole and a first lock groove disposed on the body, the guide cone hole and the first lock groove being connected; the guide cone hole is used to guide the bottom of the first lock hook into the lock, and the shape of the first lock groove is adapted to the bottom of the first lock hook to achieve a locking engagement.
[0013] Furthermore, the front locking structure includes a second locking hook and a second locking groove. The second locking groove is disposed on the body, and the second locking hook is disposed at the front end of the hatch body. The second locking hook and the second locking groove are detachably connected.
[0014] Furthermore, the bottom of the hatch body, where it mates with the fuselage, is provided with an annular rubber pad.
[0015] Furthermore, the first locking assembly includes three sliding locking structures.
[0016] Compared with existing technologies, the sliding multi-point locking hatch of this utility model has the following advantages:
[0017] 1. The first and second locking components are symmetrically distributed on the left and right sides of the hatch body. Through the linkage of the hatch body, multiple sliding locking structures are integrated into a coordinated action unit. This allows all the locking hooks on the left and right sides to move synchronously and accurately insert into the corresponding locking holes of the aircraft body during the longitudinal sliding of the hatch body. The single linear sliding operation replaces the traditional independent disassembly and assembly process of each locking point, significantly reducing the complexity of operation and time cost. At the same time, it ensures that the locking force is evenly transmitted to the periphery of the hatch body, avoiding deformation or sealing failure caused by local stress concentration. Thus, the engineering requirements for rapid disassembly and assembly in the field are met while maintaining high structural reliability.
[0018] 2. When the hatch body slides, all first locking hooks are forced to move synchronously along a preset trajectory. The progressive convergence characteristics of the guide cone hole are used to automatically correct the docking deviation between the locking hook and the locking groove, so that the bottom of the locking hook is accurately embedded in the matching first locking groove to form a mechanical interlock. Not only does it achieve multi-point synchronous locking through single-degree-of-freedom sliding action, eliminating the multiple repetitive operations required by traditional quick-release devices, but it also maintains the stability of the locked state under vibration and impact conditions by relying on the adaptive guiding capability of the guide cone hole and the matching characteristics of the locking hook and locking groove. This fundamentally solves the problems of low efficiency and reliability degradation caused by independent operation of multiple locking points. Attached Figure Description

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0033] A sliding multi-point locking hatch, such as Figure 1 As shown, the device includes a hatch body 200, a first locking assembly 2, a second locking assembly 4, a front locking structure 1, and a rear locking structure 3. The first locking assembly 2 and the second locking assembly 4 are symmetrically arranged on the left and right sides of the hatch body 200, and the first locking assembly 2 and the second locking assembly 4 have the same structure. The front locking structure 1 is located at the front end of the hatch body 200, and the rear locking structure 3 is located at the rear end of the hatch body 200. The first locking assembly 2, the second locking assembly 4, the front locking structure 1, and the rear locking structure 3 are all used to achieve a detachable connection between the hatch body 200 and the fuselage 100.
[0034] The front locking structure 1 includes a second locking hook and a second locking groove. The second locking groove is located on the fuselage 100, and the second locking hook is located at the front end of the canopy body 200. The second locking hook and the second locking groove are detachably connected. An annular rubber pad is provided on the bottom surface of the canopy body 200 that mates with the fuselage 100. In this embodiment, the rear locking structure 3 adopts the locking structure described in "02110281057.3 - Locking Structure of UAV Assembly / Disassembly Structure".
[0035] The first locking assembly 2 includes multiple sliding locking structures arranged on the side of the hatch body 200. When the hatch body 200 slides longitudinally along the fuselage 100, the locking hooks of the multiple sliding locking structures move synchronously and simultaneously enter the corresponding locking holes on the fuselage 100, thereby locking the hatch body 200. The first locking assembly 2 includes three sliding locking structures.
[0036] The first locking assembly 2 and the second locking assembly 4 are symmetrically distributed on the left and right sides of the hatch body 200. Through the linkage of the hatch body 200, multiple sliding locking structures are integrated into a coordinated action unit. This allows all the locking hooks on the left and right sides to move synchronously and accurately insert into the corresponding locking holes of the body 100 during the longitudinal sliding of the hatch body 200. The single linear sliding operation replaces the traditional independent disassembly and assembly process of each locking point, significantly reducing the complexity of operation and time cost. At the same time, it ensures that the locking force is evenly transmitted to the periphery of the hatch body 200, avoiding deformation or sealing failure caused by local stress concentration. Thus, the engineering requirements for rapid disassembly and assembly in the field are met while maintaining high structural reliability.
[0037] like Figure 5-7 As shown, the first locking assembly 2 includes a locking hook structure and a locking hole structure 10. The top of the locking hook structure is fixedly connected to the hatch body 200, and the bottom of the locking hook structure is detachably connected to the locking hole structure 10. The locking hole structure 10 is provided on the body 100.
[0038] The locking hook structure includes a support block 21 and a first locking hook 22. The top of the first locking hook 22 is connected to the support block 21, and the support block 21 is glued to the outer wall of the hatch body 200. The bottom of the first locking hook 22 is detachably connected to the locking hole structure 10. The locking hole structure 10 includes a guide cone hole and a first locking groove provided on the body 100. The guide cone hole communicates with the first locking groove. The guide cone hole is used to guide the bottom of the first locking hook 22 into place, and the shape of the first locking groove is adapted to the bottom of the first locking hook 22 to achieve a locking engagement.
[0039] When the hatch body 200 slides, all the first locking hooks 22 are forced to move synchronously along a preset trajectory. The progressive convergence characteristics of the guide cone hole are used to automatically correct the docking deviation between the locking hook and the locking groove, so that the bottom of the locking hook is precisely embedded in the matching first locking groove to form a mechanical interlock. Not only does it achieve multi-point synchronous locking through single-degree-of-freedom sliding action, eliminating the multiple repetitive operations required by traditional quick-release devices, but it also maintains the stability of the locked state under vibration and impact conditions by relying on the adaptive guiding capability of the guide cone hole and the matching characteristics of the locking hook and locking groove. This fundamentally solves the problems of low efficiency and reliability degradation caused by independent operation of multiple locking points.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
