Description

Technical Field

[0001] This utility model relates to the field of drone connection technology, specifically a drone quick-release arm locking structure. Background Technology

[0002] As a type of remotely controlled unmanned aerial vehicle, the drone's arm is the core structure connecting the fuselage and power components (such as motors and propellers). The reliability of the connection between the arm and the fuselage directly affects flight safety. Currently, the connection methods between the drone's arm and the main fuselage include fixed connection and detachable connection. Fixed connection often uses multiple screws for fixing, which requires removing each screw one by one during disassembly, making it cumbersome. Detachable connection often uses simple pins or clips for quick connection. Although this type of structure improves the speed of assembly and disassembly, its structure is relatively simple and the sealing of the connection point is low. Dust or rainwater from the external environment can enter through the connection point, causing corrosion of internal electrical connectors and affecting the normal use of the drone. Therefore, we propose a quick-release drone arm locking structure to solve the above problems. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figure 1-8 As shown, this utility model provides a quick-release arm locking structure for a drone, including a drone body 1. Rotating components 11 are fixedly provided at each of the four corners of the drone body 1. Arm bodies 2 are provided at the ends of the rotating components 11. Male electrical connectors 4 are fixedly fastened at the ends of the rotating components 11. Female electrical connectors 41 corresponding to the male electrical connectors 4 are fixedly fastened at the ends of the arm bodies 2 near the rotating components 11. The male electrical connectors 4 and the corresponding female electrical connectors 41 are snapped together. A locking mechanism 3 is provided between the rotating components 11 and the arm bodies 2. The locking mechanism 3 includes a locking sleeve 31 and a locking clip 32. The locking sleeve 31 is fixedly installed on the end of the rotating part 11 by screws, and the locking clip 32 is fixedly installed on the end of the arm body 2 by screws. The locking clip 32 is slidably engaged in the locking sleeve 31. The bottom of the locking clip 32 is integrally formed with a positioning clip 321, which is slidably engaged in the bottom of the locking sleeve 31. The locking sleeve 31 and the locking clip 32 are engaged to connect the rotating part 11 and the arm body 2. The locking sleeve 31 and the locking clip 32 provide a covering support connection between the rotating part 11 and the arm body 2, thereby increasing the connection stability. A sealing frame 33 is fixedly installed on the inner side of the locking frame 31, and a sealing frame 34 is fixedly installed on the inner side of the locking clip frame 32. The sealing frame 34 is movably clipped into the sealing frame 33. A first sealing gasket 332 is provided on the inner side of the sealing frame 33, and the first sealing gasket 332 contacts the end of the sealing frame 34. A second sealing gasket 342 is movably sleeved on the outer side of the sealing frame 34, and the end of the sealing frame 33 contacts the second sealing gasket 342. This multi-level sealing connection between the sealing frame 33 and the sealing frame 34 increases the sealing effect, thereby sealing the connection part of the male electrical connector 4 and the female electrical connector 41, preventing dust or rainwater from the external environment from entering through the connection part and causing corrosion of the internal male electrical connector 4 and the female electrical connector 41, which would affect the normal use of the UAV. The top of the locking frame 32 is rotatably fitted with a positioning block 35. The inner side of the locking sleeve 31 is provided with a positioning groove 351 corresponding to the positioning block 35. The two ends of the positioning block 35 are movably engaged in the positioning groove 351. The positioning between the locking sleeve 31 and the locking frame 32 is achieved by the positioning block 35, thereby positioning between the rotating part 11 and the arm body 2. A rotating cylinder 36 is fixedly mounted in the middle of the positioning block 35. The rotating cylinder 36 is rotatably engaged with the locking frame 32. A connecting pin 361 is movably mounted in the rotating cylinder 36. A spring 362 is movably sleeved on the outside of the connecting pin 361. The top of the connecting pin 361 extends to the top of the rotating cylinder 36 and the top of the locking frame 32. A fixing torque 37 is fixedly mounted on the top of the connecting pin 361. A limiting protrusion 371 is fixedly mounted on the bottom of the fixing torque 37. A limiting groove 372 is opened at the top of the locking frame 32 to cooperate with the limiting protrusion 371. There are multiple limiting grooves 372. The limiting protrusion 371 is movably engaged in one set of limiting grooves 372 to position the fixing torque 37, thereby positioning the rotating cylinder 36 and the positioning block 35.

[0025] A third sealing gasket 331 is provided on the side of the sealing frame 33 away from the first sealing gasket 332. The third sealing gasket 331 contacts the end of the rotating member 11 to seal the end of the rotating member 11 and the sealing frame 33. A fourth sealing gasket 341 is provided on the side of the sealing frame 34 away from the second sealing gasket 342. The fourth sealing gasket 341 contacts the end of the arm body 2 to seal the end of the sealing frame 34 and the end of the arm body 2.

[0026] Working principle: In the initial installation state, the positioning block 35 is fully retracted and locked in the locking frame 32. Subsequently, the rotating part 11 and the arm body 2 are installed. The locking frame 31 is fixedly installed on the end of the rotating part 11 with screws. The locking frame 32 is fixedly installed on the end of the arm body 2 with screws. The third sealing gasket 331 is in contact with the end of the rotating part 11, and the fourth sealing gasket 341 is in contact with the end of the arm body 2. Subsequently, the locking frame 32 is slidably engaged in the locking sleeve 31 to engage the locking sleeve 31 and the locking frame 32. At the same time, the male electrical connector 4 is engaged in the female electrical connector 41 to make an electrical connection, thereby connecting the rotating part 11 and the arm body 2. The locking sleeve 31 and the locking frame 32 provide a covering support connection for the connection between the rotating part 11 and the arm body 2. At this time, the ends of the first sealing gasket 332 and the sealing frame 34 are in contact, and the end of the sealing sleeve 33 is in contact with the second sealing gasket 342, so as to form a multi-level sealing connection between the sealing sleeve 33 and the sealing frame 34, thereby increasing the sealing effect and sealing the connection part of the male electrical connector 4 and the female electrical connector 41, preventing dust or rainwater from the external environment from entering through the connection part and causing corrosion of the internal male electrical connector 4 and the female electrical connector 41, which would affect the normal use of the UAV. At this time, the positioning block 35 and the positioning groove 351 are in the same position. Then, the manual upward fixing knob 37 drives the connecting pin 361 to move upward, squeezing the spring 362. The limiting protrusion 371 disengages from the corresponding limiting groove 372. Then, the fixing knob 37 is rotated. At this time, the rotating cylinder 36 and the positioning block 35 are rotated. At this time, the two ends of the positioning block 35 are movably engaged in the positioning groove 351 to perform positioning between the locking sleeve 31 and the locking frame 32, thereby positioning between the rotating part 11 and the machine arm body 2. The fixing knob 37 is released, and the spring 362 returns to its original position, causing the limiting protrusion 371 to move and engage in the corresponding limiting groove 372 to position the rotating cylinder 36 and the positioning block 35. When the arm body 2 needs to be disassembled, simply move the fixing knob 37 upward manually to move the connecting pin 361 upward, compress the spring 362, and disengage the limiting protrusion 371 from the corresponding limiting groove 372. Then, rotate the fixing knob 37. At this time, the rotating cylinder 36 and the positioning block 35 will rotate. At this time, the two ends of the positioning block 35 will disengage from the positioning groove 351 and be completely stored in the locking frame 32. Then, move the arm body 2 for quick disassembly.
