Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a quick-release self-locking rotor for UAVs. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and their own program control devices. With the widespread application of UAV technology in industrial fields such as agricultural plant protection, logistics transportation, and surveying and inspection, higher demands are being placed on the operational efficiency, ease of maintenance, and flight safety of UAVs. As a key power component of UAVs, the efficiency of their assembly and disassembly and the reliability of their connections are of paramount importance.

[0003] In traditional drone designs, rotor connections are often made using screws or nuts. This requires specialized tools for assembly and disassembly, making the process cumbersome and time-consuming. This approach fails to meet the efficiency requirements of field operations or scenarios where frequent rotor replacements are needed, and it hinders the speed of installation and disassembly. Utility Model Content

[0004] The purpose of this invention is to provide a quick-release self-locking rotor for unmanned aerial vehicles (UAVs) to solve the problem of inconvenient rotor assembly and disassembly mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions: A quick-release self-locking rotor for a drone includes a rotor body, a mounting connector is disposed on the lower part of the rotor body, a quick-release mechanism is fixedly connected to the bottom end of the mounting connector, and a locking mechanism is disposed on the surface of the mounting connector. The quick-release mechanism includes a limiting post, four fixing blocks and a snap-fit ​​base. The four fixing blocks are arranged in a circular array on the outer wall of the limiting post. The snap-fit ​​base is provided with a limiting slot for fixing the blocks. The snap-fit ​​base is installed at the rotation position of the drone body. The locking mechanism includes a hollow limiting member fixedly connected to the top of the mounting connector, a connecting rod passing through the upper part of the hollow limiting member, a locking rod fixedly connected to the bottom end of the connecting rod, a fixing member fixedly connected to the outer side wall of the locking rod, and an alloy return spring sleeved on the surface of the connecting rod.

[0006] As a further embodiment of this utility model: the upper surface and the inner bottom wall of the fixing block and the snap-fit ​​base are both provided with a limiting through-hole, and the limiting through-hole and the locking rod are adapted to the cross section formed by the fixing member.

[0007] As a further embodiment of this utility model: a locking slot adapted to the locking rod is provided in the limiting through-hole located on the snap-fit ​​base.

[0008] As a further embodiment of this utility model: the fixed connection height of the fixing block is equal to half of the limiting post, and the inner circle size formed on the limiting post and the snap-fit ​​base is equal.

[0009] As a further embodiment of this utility model: the size of the locking base on the outer wall of the limiting slot is adapted to the outer wall of the fixing block, the fixing block rotates once in the limiting slot, and the fixing block is locked below the limiting slot.

[0010] As a further embodiment of this utility model: the alloy return spring is sleeved on the surface of the connecting rod, one end of the alloy return spring is fixedly connected to the inner top wall of the hollow limiting member, and the other end of the alloy return spring overlaps in the groove of the locking rod to facilitate the rotation of the locking rod.

[0011] As a further embodiment of this utility model, an adjusting component is rotatably connected above the connecting rod.

[0012] The beneficial effects of this utility model are: 1. This drone uses a quick-release self-locking rotor. Through the quick-release mechanism, the rotor body and the drone body can be quickly engaged and disengaged by the cooperation of the limiting post, the fixing block and the limiting slot in the locking base. The whole process does not require any tools, which greatly improves the efficiency of disassembly and assembly and meets the high requirements for convenience in field operations or scenarios that require frequent rotor replacement.

[0013] 2. This drone uses a quick-release self-locking rotor. Through the setting of the locking mechanism, the elasticity of the alloy return spring drives the locking rod and the fixing part to move downward, so that they can be accurately inserted and locked in the limited through hole.

Detailed Implementation

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-4 As shown, a quick-release self-locking rotor for a drone includes a rotor body 1, a mounting connector 2 is disposed below the rotor body 1, a quick-release mechanism 3 is fixedly connected to the bottom end of the mounting connector 2, and a locking mechanism 4 is disposed on the surface of the mounting connector 2. The quick-release mechanism 3 includes a limiting post 301, four fixing blocks 302, and a snap-fit ​​base 303. The four fixing blocks 302 are arranged in a circular array on the outer wall of the limiting post 301. The snap-fit ​​base 303 is provided with a limiting slot 304 for fixing blocks 302. The snap-fit ​​base 303 is installed at the rotation position of the UAV body. Through the setting of the quick-release mechanism 3, the cooperation between the limiting post 301, the fixing blocks 302, and the limiting slot 304 in the snap-fit ​​base 303 realizes the quick snap-fit ​​and separation between the rotor body 1 and the rotation position of the UAV body. The whole process does not require any tools, which greatly improves the disassembly and assembly efficiency and meets the high requirements for convenience in field operations or scenarios where frequent rotor replacement is required. The locking mechanism 4 includes a hollow limiting member 401 fixedly connected to the top of the mounting connector 2. A connecting rod 402 passes through the upper part of the hollow limiting member 401. A locking rod 403 is fixedly connected to the bottom end of the connecting rod 402. A fixing member 404 is fixedly connected to the outer wall of the locking rod 403. An alloy return spring 405 is sleeved on the surface of the connecting rod 402. By setting up the locking mechanism 4, the elastic force of the alloy return spring 405 drives the locking rod 403 and the fixing member 404 to move downward, so that they can be accurately inserted and locked in the limiting through-hole 5. Then, the connecting rod 402 is rotated so that the fixing member 404 can be locked in the locking slot 6. This effectively prevents the rotor from loosening due to vibration when rotating at high speed, providing double insurance and significantly improving the reliability of the connection and flight safety.

[0019] like Figure 2As shown, a limiting through-hole 5 is provided on the upper surface and inner bottom wall of one of the fixing blocks 302 and the locking base 303. The limiting through-hole 5 and the locking rod 403 are adapted to the cross section formed by the fixing member 404. An adjusting member 7 is rotatably connected above the connecting rod 402. The setting of the adjusting member 7 and the connecting rod 402 facilitates the user to manually operate and control the lifting and lowering of the locking rod 403. like Figure 4 As shown, a locking slot 6 adapted to the locking rod 403 is provided in the limiting through-hole 5 on the locking base 303. The locking slot 6 limits the locking rod 403 and prevents it from rotating accidentally, thereby achieving a firm locking effect. like Figure 2 As shown, the fixed connection height of the fixed block 302 is equal to half of the limit post 301. The inner ring size formed on the limit post 301 and the snap-fit ​​base 303 is equal. By setting a specific ratio between the height of the limit post 301 and the fixed block 302, it is possible to ensure that the rotor can be accurately aligned and smoothly introduced during installation, while ensuring that the fixed block 302 can be completely submerged in the limit slot 304 to achieve stable load bearing. like Figure 2 , Figure 4 As shown, the size of the outer wall of the locking base 303 on the limiting slot 304 is adapted to the outer wall of the fixing block 302. The fixing block 302 rotates once inside the limiting slot 304 and is locked in the lower part of the limiting slot 304. The setting of the limiting slot 304 and the fixing block 302 achieves the fixing function. like Figure 3 As shown, the alloy return spring 405 is sleeved on the surface of the connecting rod 402. One end of the alloy return spring 405 is fixedly connected to the inner top wall of the hollow limiting member 401, and the other end of the alloy return spring 405 overlaps in the groove of the locking rod 403, which facilitates the rotation of the locking rod 403. By setting the alloy return spring 405, it provides continuous and stable downward pressure to the locking rod 403 to maintain the locked state, while allowing the locking rod 403 to rotate freely when unlocking.

[0020] The working principle of this utility model is as follows: During installation, the operator holds the rotor body 1 and aligns the limiting post 301 and fixing block 302 of the quick-release mechanism 3 with the entrance of the locking base 303. Then, the operator presses down and rotates the rotor body 1. At this time, the fixing block 302 slides into the track of the limiting slot 304. When rotated to the correct position, the fixing block 302 is locked below the limiting slot 304, completing the initial mechanical connection and bearing. During this process, the locking rod 403 of the locking mechanism 4 pops out downward under the automatic action of the alloy return spring 405, passing through the limiting through-hole 5 on the fixing block 302 and the locking base 303. Then, the connecting rod 402 is rotated so that the fixing part 404 can be locked into the locking slot 6, achieving secondary locking and preventing the rotor from reversing and loosening. During disassembly, the operator lifts the adjusting part 7 upward, and the connecting rod 402 drives the locking rod 403 to overcome the elastic force of the alloy return spring 405 and move upward, so that it passes through the locking slot 6 and the limiting through-hole 5. Completely remove the rotor body 1, then rotate it in the opposite direction to make the fixing block 302 disengage from the track of the limiting slot 304, so that the entire rotor can be pulled upwards to complete the quick disassembly.
