Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to a quick-disassembly structure for UAV propellers. Background Technology

[0002] Drones have developed rapidly in recent years and are now used in many aspects of life, such as aerial photography, agricultural sowing, pesticide spraying, and firefighting. As one of the important components of drones, the propeller is driven by the motor and generates lift by cutting the air at high speed. It is the main power source of drones, especially rotary-wing drones. Drones used in aerial photography and agriculture have similar structures. Due to the large payload, the propellers are also large. When connecting the propellers to the motor, screws are used. During outdoor operations, it is inevitable that a blade will be damaged and need to be replaced. However, due to the screw connection, disassembly and replacement outdoors is quite troublesome. Summary of the Invention

[0003] The present invention aims to solve the technical problems existing in the prior art and provide a quick-disassembly structure for drone propellers.

[0004] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a quick-release structure for a drone propeller, comprising a propeller and a base, wherein the propeller is embedded in the base, and the base includes a mounting shell, the mounting shell being a cylindrical structure with an open top, the interior of the mounting shell having two symmetrically arranged first limiting platforms, two first limiting grooves forming between the two first limiting platforms, a column being provided in the mounting shell between the two first limiting platforms, the top of the column having two symmetrically arranged flaps, and the two flaps being rotatably connected to the top of the column, each of the two first limiting platforms having a sliding mechanism. The sliding groove extends laterally through the first limiting platform. A plug is slidably connected within the sliding groove. The plug includes a mating inclined surface, which faces upward. A middle mating block is provided at the middle position of the lower surface of the blade. A recessed hole is provided at the position corresponding to the middle mating block on the upper surface of the blade. A slot is provided at the middle position of the middle mating block. The width of the slot is the same as the width of the column, and the slot extends upward into the recessed hole. A second limiting groove that mates with the first limiting platform is provided in the middle mating block. A second limiting platform that mates with the first limiting groove is provided. A slot that mates with the plug is opened on the inner wall of the second limiting groove.

[0005] Preferably, a cover plate is fixedly installed at the sliding groove opening of the first limiting platform of the mounting housing, and a U-shaped handle is slidably connected in the cover plate, with the inner end of the U-shaped handle fixedly connected to the insert block.

[0006] Preferably, a strong magnet is provided on the recessed holes on both sides of the slot for adsorbing the flip plate.

[0007] Preferably, a spring is connected between the cover plate and the insert block, with the two ends of the spring connected to the insert block and the cover plate respectively.

[0008] Preferably, the depth of the recessed hole is the same as the thickness of the flap.

[0009] Preferably, the combined thickness of the two flaps is the same as the thickness of the column.

[0010] Preferably, the bottom of the mounting housing is provided with multiple connecting screw holes.

[0011] The beneficial effects of this utility model are as follows: By setting up an installation housing and an intermediate mating block, an insert block is set in the sliding groove of the installation housing, and a slot that mates with the insert block is set on the intermediate mating block of the blade. The engagement of the insert block and the slot allows for quick connection between the blade and the base. Pulling the U-shaped handle to remove the insert block from the slot allows for quick separation between the blade and the base. This quick connection and quick separation facilitates rapid blade replacement outdoors when tools are unavailable. By setting up a column and a flap, after the column and flap pass through the slot of the intermediate mating block, the flap flips down and is absorbed into the recessed hole, which provides secondary fixation for the blade and increases the connection strength.

[0019] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0020] Example: A quick-release structure for drone propellers, such as Figures 1-6 As shown, the device includes a blade 1 and a base 2. The blade 1 is embedded in the base 2. The base 2 includes a mounting housing 3, which is a cylindrical structure with an open top. Inside the mounting housing 3 are two symmetrically arranged first limiting platforms 4, forming two first limiting grooves 5. A column 6 is located within the mounting housing 3 between the two first limiting platforms 4. Two flaps 7 are symmetrically arranged on the top of the column 6, and the two flaps 7 are rotatably connected to the top of the column 6. Each of the two first limiting platforms 4 has a sliding groove 8 that extends laterally through the first limiting platform 4, allowing for sliding connection within the sliding groove 8. The device includes an insert block 9, which has a mating inclined surface 10 facing upwards. A middle mating block 11 is provided at the middle position of the lower surface of the blade 1. A recessed hole 12 is provided at the position corresponding to the middle mating block 11 on the upper surface of the blade 1. A slot 13 is provided at the middle position of the middle mating block 11. The width of the slot 13 is the same as the width of the column 6, and the slot 13 extends upwards into the recessed hole 12. The middle mating block 11 has a second limiting groove 14 that mates with the first limiting platform 4, and a second limiting platform 15 that mates with the first limiting groove 5. A slot 16 that mates with the insert block 9 is provided on the inner wall of the second limiting groove 14.

[0021] A cover plate 17 is fixedly installed at the opening of the sliding groove 8 in the first limiting platform 4 of the mounting housing 3. A U-shaped handle 18 is slidably connected in the cover plate 17, and the inner end of the U-shaped handle 18 is fixedly connected to the insert block 9.

[0022] A strong magnet 19 is provided on each of the recessed holes 12 on both sides of the slot 13 to attract the flip plate 7; a spring 20 is connected between the cover plate 17 and the insert block 9, and the two ends of the spring 20 are respectively connected to the insert block 9 and the cover plate 17; the depth of the recessed hole 12 is the same as the thickness of the flip plate 7.

[0023] The combined thickness of the two flaps 7 is the same as the thickness of the column 6; the bottom of the mounting housing 3 is provided with multiple connecting screw holes 21.

[0024] The principle of this utility model is as follows: In use, the base 2 is first connected to the drive shaft of the motor through the connecting screw hole 21. First, the two flip plates 7 are flipped up, and the slot 13 in the blade 1 is aligned with the flip plate 7 and the column 6. The blade 1 is then inserted into the base 2. During the insertion process, the second limiting groove 14 in the intermediate mating block 11 will press the insertion block 9 set in the first limiting platform 4 in the mounting housing 3. The pressing of the mating inclined surface 10 in the insertion block 9 will push the insertion block 9 outward. After the blade 1 is fully inserted into the mounting housing 3 of the base 2, the insertion block 9 and the slot 16 in the blade 1 are at the same height. The insertion block 9 moves inward by the elastic force of the spring 20 and is locked into the slot 16 of the blade 1 to achieve fixation. The two flip plates 7 are flipped down and placed in the recessed hole 12. They are then attracted by the strong magnet 19 to achieve secondary fixation.

[0025] When it is necessary to remove it, flip the two flaps 7 upwards, pull the U-shaped handle 18 on the cover plate 17 to slide the insert 9 out of the slot 16, and the blade 1 can be removed from the base 2. After releasing the U-shaped handle 18, the insert 9 is reset by the spring 20, so that it can be re-inserted into the slot 16 of the blade 1 during installation.

[0026] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
