[0028] The following is combined Figures 1 to 4 This invention describes a quick-release device, a drone mission payload expansion mechanism, and a drone.

[0029] One embodiment of this utility model provides a quick-release device, see [link]. Figure 1 As shown, the quick-release device includes a quick-release base 1, a quick-release head 2, and a positioning connecting device 3. The quick-release base 1 includes a quick-release base body 11, a sliding rail 12 is formed inside the quick-release base body 11, and a positioning hole 13 is formed on the side wall of the quick-release base body 11. The quick-release head 2 includes a quick-release head body 21, which is slidably disposed on the sliding rail 12, and a positioning groove 22 is formed on the side wall of the quick-release head body 21. The quick-release head 2 has a disassembled state and an installed state. In the disassembled state, the quick-release head body 21 is away from the sliding rail 12. In the installed state, the quick-release head body 21 is located inside the sliding rail 12, and the positioning groove 22 is opposite to the positioning hole 13. The positioning connecting device 3 is movably disposed through the positioning hole 13, and is adapted to be disposed in the positioning groove 22 when the quick-release head 2 is in the installed state, so as to connect and fix the quick-release base 1 and the quick-release head 2.

[0030] It can be understood that such a quick-release device in this embodiment realizes the quick disassembly and assembly of two devices through the quick-release base 1 and the quick-release head 2, and is applicable to the quick disassembly and assembly of the UAV mission payload module on the UAV. Fix the quick-release base 1 on the UAV fuselage, ensure that the sliding track 12 faces outward, and the quick-release head 2 can be pre-connected and installed with the UAV mission payload module. Push the quick-release head 2 along the sliding track 12 until the positioning groove 22 is aligned with the positioning hole 13. Pass the positioning connection device 3 through the positioning hole 13 and the positioning groove 22 to realize the connection and fixation of the quick-release base 1 and the quick-release head 2, and then the UAV mission payload module can be quickly installed on the UAV. When disassembly is required, manually pull the positioning connection device 3, and the quick-release head 2 can be slid out along the sliding track 12 to achieve quick separation. The quick-release device in this embodiment only needs to push and pull the quick-release head 2 during the disassembly and assembly process, without tools such as wrenches, greatly improving the efficiency and realizing the quick disassembly and assembly of the UAV payload installation.

[0031] In some embodiments of the quick-release device of the present utility model, as shown in Figure 2 shown, the quick-release base body 11 is a "C" - shaped structure, including two opposite side plates 111 and an inner plate 112 connecting the two side plates 111. A quick-release base cover plate 14 is installed on one end face of the quick-release base body 11. The quick-release base body 11 and the quick-release base cover plate 14 enclose the internal space of the quick-release base 1. Parallel sliding tracks 12 are formed at the ends of the two side plates 111 away from the quick-release base cover plate 14. The sliding tracks 12 are located in the internal space of the quick-release base 1, and a positioning hole 13 is provided on one of the side plates 111.

[0032] It can be understood that the two opposite side plates 111 and the inner plate 112 can be integrally formed to form the quick-release base body 11 with a "C" - shaped structure. The frame structure reduces the weight and meets the UAV load requirements. The quick-release base cover plate 14 is installed on the upper end face of the quick-release base body 11 to form a closed internal space, enhancing the structural strength and having excellent anti-vibration performance. It can form a protective structure for the quick-release device and prevent equipment damage or even falling due to impact or flight errors. Parallel sliding tracks 12 are formed at the lower ends of the two side plates 111 to ensure that the quick-release head 2 slides smoothly without jamming.

[0033] As shown in Figure 3 shown, the quick-release head body 21 is a "square" - shaped structure. A quick-release head cover plate 23 is installed on one end face of the quick-release head body. The quick-release head body 21 and the quick-release head cover plate 23 enclose the internal space of the quick-release head 2.

[0034] It can be understood that the "mouth" - shaped structure of the quick - release head body 21 and the quick - release head cover plate 23 fixed by screws form a closed structure, reserving an internal electrical connection space. A positioning groove 22 is milled on the side wall, which matches the positioning hole 13 of the quick - release base 1. The "mouth" - shaped quick - release head body 21 and the "匚" - shaped quick - release base body 11 fit perfectly with small sliding resistance. Electrical connectors or sensor wirings can be integrated inside the quick - release head body 21.

[0035] In some embodiments of the quick - release device of the present utility model, in combination Figure 1 and Figure 4 As shown, the positioning and connecting device 3 includes a connecting pin 31 and a return spring 32. The connecting pin 31 is inserted into the positioning hole 13, and the length of the connecting pin 31 is greater than the depth of the positioning hole 13; the return spring 32 is sleeved on the outer peripheral surface of the connecting pin 31. One end of the return spring 32 is fixed to the positioning hole 13, and the other end is connected to the connecting pin 31.

[0036] It can be understood that when the connecting pin 31 is inserted into the positioning hole 13 and the return spring 32 is sleeved on the outer peripheral surface of the connecting pin 31, during installation, the operator pulls the connecting pin 31, inserts the quick - release head 2 into the quick - release base 1, and pushes it to the bottom of the quick - release base 1. The connecting pin 31 automatically slides into the positioning groove 22 of the quick - release head 2 under the action of the return spring 32, realizing the positioning and fixing of the quick - release head 2 in the quick - release base 1. During disassembly, the operator pulls the connecting pin 31 and then pulls out the quick - release head 2 from the quick - release base 1, realizing the quick disassembly of the quick - release head 2 and the quick - release base 1. In this embodiment, automatic locking is achieved by the assistance of the return spring 32, reducing manual operation steps. The pre - tightening force of the return spring 32 ensures that the connecting pin 31 is always in a working state, avoiding accidental loosening.

[0037] Continuing to refer to Figure 4 As shown, a first limiting portion 131 is formed at a position in the positioning hole 13 far from the positioning groove 22, and a second limiting portion 311 is formed on the connecting pin 31. One end of the return spring 32 contacts the first limiting portion 131, and the other end contacts the second limiting portion 311. Specifically, an annular groove is machined in the positioning hole 13 as the first limiting portion 131, and a flange is added to the connecting pin 31 as the second limiting portion 311. Both ends of the return spring 32 respectively abut against the first limiting portion 131 and the second limiting portion 311, preventing the axial movement of the connecting pin 31. The double - limiting structure of the first limiting portion 131 and the second limiting portion 311 avoids the deflection of the return spring 32 and the connecting pin 31, prolonging the service life. Under the action of the first limiting portion 131 and the second limiting portion 311, the return spring 32 has a pre - tightening force. Under the pre - tightening force of the return spring 32, the connecting pin 31 can automatically return to its original position every time it is pulled out, ensuring the reliability of the next installation.

[0038] Furthermore, in some specific examples, the positioning connection device 3 also includes a guide ring 33 and a pull ring 34, see again Figure 4 As shown, the guide ring 33 is positioned within the positioning hole 13 near the positioning groove 22. The center of the guide ring 33 has a guide hole adapted to the connecting pin 31, through which the connecting pin 31 passes. A pull ring 34 is connected to the end of the connecting pin 31 furthest from the positioning groove 22. It can be understood that the guide ring 33 is pressed into the port of the positioning hole 13 facing the quick-release seat 1. The guide hole in the center of the guide ring 33 has a clearance fit (≤0.1mm) with the connecting pin 31. The guide ring 33 guides the movement of the connecting pin 31, preventing axial displacement and ensuring accurate engagement with the positioning groove 22. The pull ring 34 is threaded to the outer end of the connecting pin 31 for easy gripping. The pull ring 34 provides a force point, facilitating quick assembly and disassembly by the operator.

[0039] In another aspect, this utility model also provides a drone mission payload extension mechanism. In some embodiments, the drone mission payload extension mechanism includes a quick-release device as described in any of the above embodiments or examples. The quick-release device's quick-release base 1 is fixed on the drone. The quick-release device's quick-release head 2 is provided with a connection hole 24. A connector is movably inserted into the connection hole. The connector is adapted to connect with the mission payload equipment.

[0040] Specifically, the quick-release mount 1 can be fixed to the underside of the UAV with bolts. The payload equipment can be equipped with quick-connect holes at the factory. By manually inserting bolts or other quick-release connectors through the connection holes 24 on the quick-release head 2 and the quick-connect holes of the payload equipment, the payload equipment can be quickly connected to the quick-release head 2. Then, the quick-release head 2 and quick-release mount 1 can be quickly disassembled to achieve rapid assembly of the payload equipment and the UAV. One UAV can be equipped with multiple payloads, eliminating the need to purchase multiple dedicated devices or adapters, thus reducing costs and management complexity.

[0041] Furthermore, in some embodiments of the UAV mission payload extension mechanism of this utility model, a first electrical connector 15 is provided inside the quick-release base 1 of the quick-release device, which is connected to the electrical system of the UAV. A second electrical connector 25 is provided on the quick-release head 2 of the quick-release device, which is adapted to be connected to the electrical system of the mission payload device via a connecting wire. When the quick-release head 2 is in the installed state, the first electrical connector 15 and the second electrical connector 25 are engaged. Specifically, a first connector holder 16 is fixed to the end of the sliding rail 12 of the quick-release base 1 of the quick-release device, and the first electrical connector 15 is fixedly inserted through the first connector holder 16. A second connector holder 26 is provided on the end face of the quick-release head 2 of the quick-release device facing the first connector holder 16, and the second electrical connector 25 is fixedly inserted through the second connector holder 26.

[0042] Understandably, the first electrical connector 15 connects to the UAV flight control system, and the second electrical connector 25 connects to the payload power / data cable. When the quick-release head 2 is pushed into the quick-release seat 1, the first electrical connector 15 and the second electrical connector 25 automatically engage, ready for immediate use upon power-on. The first electrical connector 15 and the second electrical connector 25 can employ anti-reverse insertion interfaces to prevent damage from accidental operation. The first connector holder 16 is fixed to the end of the sliding rail 12 with screws, and the second connector holder 26 is installed on the end face of the quick-release head 2. When the quick-release head 2 is pushed to the bottom of the quick-release seat 1, the distance between the first connector holder 16 and the second connector holder 26 is ≤1mm, ensuring that the first electrical connector 15 and the second electrical connector 25 are fully engaged. By fixing the first electrical connector 15 and the second electrical connector 25 with the first connector holder 16 and the second connector holder 26 respectively, vibration-induced poor contact is avoided, lateral stress on the connectors during insertion and removal is reduced, and durability is extended. During installation, the ground operator pulls open the connecting pin 31 using the pull ring 34, inserts the quick-release head 2 into the quick-release seat 1, and pushes it to the bottom. Under the action of the return spring 32, the connecting pin 31 automatically slides into the positioning groove 22 of the quick-release head 2, simultaneously completing the connection of the structure and the electrical connector. During disassembly, the ground operator pulls open the connecting pin 31 using the pull ring 34, pulls out the quick-release head 2 from the quick-release seat 1, simultaneously completing the disassembly of the structure and the disconnection of the electrical connector.

[0043] This utility model also provides a drone, including the drone mission payload expansion mechanism in any of the above embodiments. It is understood that the drone of this utility model, equipped with the aforementioned drone mission payload expansion mechanism, allows for quick and easy installation and removal of the drone mission payload module from the drone. This is convenient and simple, allowing ground personnel to simultaneously achieve structural installation and electrical connection of the payload through simple plug-and-play operations.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
