[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0031] refer to Figures 1 to 6 The present invention discloses the following embodiments:

[0032] A drone includes a drone body 1, a landing gear body 2, and a disassembly / assembly structure disposed between the drone body 1 and the landing gear body 2. The disassembly / assembly structure includes a disassembly / assembly base 3 and a disassembly / assembly plate 4. The disassembly / assembly base 3 is fixedly disposed on or integrally formed on the lower side of the drone body 1 by fasteners (in this embodiment, it is fixedly connected by fasteners). The disassembly / assembly base 3 has a disassembly / assembly channel 301. A locking seat 5 is provided at the end of the disassembly / assembly channel 301. Specifically, in this embodiment, the locking seat 5 is fixedly installed on the disassembly / assembly base 3 by bolts, and the locking seat 5 has an internal receiving chamber. The landing gear body 2 is fixedly disposed on the lower side of the disassembly / assembly plate 4 by fasteners. The disassembly / assembly plate 4 can pass through the disassembly / assembly channel 301. A locking end 401 is provided at one end of the disassembly / assembly plate 4 that passes through the disassembly / assembly channel 301. The locking plate 4 is inserted into the locking seat 5. The locking seat 5 is equipped with a limiting mechanism, which defines a limiting state and a release state. When the limiting mechanism is in the limiting state, the locking end 401 is restricted from entering / exiting the receiving chamber of the locking seat 5. When the limiting mechanism is in the release state, the locking end 401 can enter / exit the receiving chamber of the locking seat 5. Specifically, as shown in the figure, in this embodiment, the disassembly plate 4 is inserted into the disassembly channel 301, and its locking end 401 is inserted into the receiving chamber of the locking seat 5. By controlling the limiting mechanism to be in the limiting state or the release state, the locking end 401 is controlled to be restricted inside the locking seat 5, thereby achieving rapid disassembly and assembly of the disassembly plate 4 and the disassembly seat 3. That is, it achieves rapid disassembly and assembly between the UAV body 1 and the landing gear body 2. The structure is simple and the disassembly and assembly are convenient.

[0033] Specifically, in this embodiment, the limiting mechanism includes a set of limiting members 6 (two oppositely arranged limiting members 6) with a preset distance between them. When the locking end 401 is inserted into the locking seat 5, the locking end 401 is located between the set of limiting members 6. One end of each limiting member 6 is hinged to the locking seat 5. When the limiting mechanism is in the limiting state, the free ends of the set of limiting members 6 approach each other. Alternatively, it can be understood that when the free ends of the set of limiting members 6 approach each other to the preset distance, the limiting mechanism enters the limiting state. The locking end 401 can no longer pass through the space between the set of limiting members 6, that is, the locking end 401 is restricted from entering / exiting the receiving cavity of the locking seat 5; when the limiting mechanism is in the released state, the free ends of the set of limiting members 6 are far apart from each other. It can also be understood that when the free ends of the set of limiting members 6 are far apart from each other to a preset distance, the limiting mechanism enters the released state. At this time, the space between the free ends of the set of limiting members 6 is available for the locking end 401 to pass through, and the locking end 401 can enter / exit the receiving cavity of the locking seat 5.

[0034] It is worth noting that, in this embodiment, the locking end 401 includes a connecting part 4011 and a limiting part 4012. One end of the connecting part 4011 is connected to the disassembly plate 4, and the other end of the connecting part 4011 is connected to the limiting part 4012. The diameter of the connecting part 4011 is smaller than the diameter of the limiting part 4012. When the limiting mechanism is in the limiting state, the distance between the free ends of a group of limiting members 6 is smaller than the diameter of the limiting part 4012, and the distance between the free ends of a group of limiting members 6 is larger than the diameter of the connecting part 4011.

[0035] The locking seat 5 is provided with a limiting unit, which is used to apply a first force to the free end of the limiting member 6 to drive the free ends of a group of limiting members 6 to maintain a tendency to move closer to each other; specifically, the limiting unit includes an elastic member 7 (compression spring) disposed in the locking seat 5, one end of the elastic member 7 abuts against the inner wall of the locking seat 5, and the other end of the elastic member 7 abuts against the free end of the limiting member 6, so that the free ends of the limiting member 6 maintain a tendency to move closer to each other under the action of the elastic potential energy of the elastic member 7.

[0036] However, since the elastic element 7 is compressible and directly disposed within the locking seat 5, it may shift to a certain extent within the locking seat 5 during long-term use. This would prevent the limiting element 6 from restricting the locking end 401 from entering / exiting the locking seat 5. Therefore, in this embodiment, a stop seat 8 is provided within the locking seat 5. The stop seat 8 has first stop grooves 9 at both ends, and the free end of the limiting element 6 has a second stop groove 10. The second stop groove 10 is located on the side of a set of limiting elements 6 that are far apart from each other. The elastic element 7 is located between the first stop groove 9 and the second stop groove 10. When the limiting mechanism is in the limiting state, the first stop groove 9 and the second stop groove 10 are aligned with each other, thereby preventing the elastic element 7 from shifting and improving the reliability of this embodiment.

[0037] Furthermore, in this embodiment, a release unit is provided on the limiting member 6. The release unit is used to control the free end of the limiting member 6 to overcome the first force, so as to drive the free ends of a group of limiting members 6 to move away from each other. Specifically, the release unit is a release member 11 connected to the hinge end of the limiting member 6. The free end of the release member 11 protrudes into the locking seat 5, and the locking seat 5 has a movable opening on the side through which the release member 11 protrudes, allowing the release member 11 to move. The operator can press the end of the release member 11 that protrudes from the locking seat 5, so that the release member 11 rotates in the movable opening. Correspondingly, the release member 11 drives the limiting member 6 to rotate, so that the limiting member 6 rotates and compresses the elastic member 7 (compression spring). At this time, the free ends of a group of limiting members 6 move away from each other, and the distance between them gradually increases, so that the locking end 401 can finally protrude from the locking seat 5. At this time, the disassembly and assembly of the disassembly and assembly base 3 and the disassembly and assembly plate 4 can be realized. The structure is simple and the operation is convenient.

[0038] In this embodiment, sliding seats 12 are provided on both sides of the disassembly base 3. The sliding seats 12 extend horizontally. The disassembly channel 301 is formed between the sliding seats 12 on both sides, and a limiting groove 13 is formed between the sliding seats 12 and the disassembly base. The disassembly plate 4 is inserted into the limiting groove 13 on both sides to restrict the disassembly plate 4 from detaching from the disassembly channel 301 in the vertical direction.

[0039] In addition, in this embodiment, the thickness of the sliding seat 12 is greater than or equal to the thickness of the locking seat 5, and a rubber pad may be provided on the lower surface of the sliding seat 12.

[0040] 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 they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
