Description

Technical Field

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

[0002] In recent years, with the rapid development of electronic technology, drones have played an increasingly important role in fields such as communication relay, environmental monitoring, forest fire prevention, geological exploration, aerial photography, power line inspection, and remote sensing. However, the disassembly and assembly of components such as the wings and fuselage, tail and fuselage, and various fuselage sections of existing drones is cumbersome, increasing maintenance costs and difficulty. Furthermore, unstable connections can cause vibrations during drone operation, affecting flight stability.

[0003] A search revealed a drone propeller quick-release and assembly mechanism (publication number CN219215416U), relating to the field of drone technology. This mechanism can at least partially solve the problems of complex assembly and disassembly of drone propellers and the presence of numerous small parts in existing technologies. This utility model provides a drone propeller quick-release and assembly mechanism comprising a propeller body and a motor, a support mounted on the motor output end, and a locking member for pressing the propeller body against the top of the support. The locking member penetrates the propeller body and is threadedly connected to the support.

[0004] The aforementioned mechanism requires a tool to be inserted into the quick-release head's mounting hole to fix the propeller, causing the locking element to rotate in the locking direction. This operation is rather cumbersome, and there are many parts involved in the connection process. During disassembly and assembly, some parts may be lost, making it impossible to fix the propeller securely. Utility Model Content

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.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] Please see Figure 1-5 As shown, this utility model is a quick-locking mechanism for a drone, comprising:

[0033] The drive shaft 300 is fixed to the output end of the UAV motor;

[0034] The locking mechanism 100 includes an upper housing square plate 110, a sliding column 120, an inclined column 130, a pull column 140, a first spring 150, a square groove 160, and a first insertion hole 170.

[0035] A square plate 110 is inserted into the drive shaft 300. A sliding column 120 is slidably connected to the side wall of the square plate 110. An inclined column 130 is slidably connected to the square hole on the top surface of the square plate 110. A pull column 140 is fixedly connected to the top surface of the inclined column 130. The two ends of the first spring 150 are respectively fixedly connected to the top surface of the inclined column 130 and the top wall of the square hole on the top surface of the square plate 110. A square groove 160 is formed at the end of the side wall of the sliding column 120. A first insertion hole 170 is formed on the side wall of the drive shaft 300. After the square plate 110 is inserted into the drive shaft 300... The sliding column 120 is inserted into the first insertion hole 170. When the sliding column 120 is inserted, the inclined column 130 is pressed into the square hole at the top of the square plate 110 by the inclined surface of the inclined column 130, and the first spring 150 is compressed. When the sliding column 120 is inserted into the position, the square groove 160 and the inclined column 130 are aligned. At this time, the first spring 150 rebounds and drives the inclined column 130 to slide out of the square hole at the top of the square plate 110 and insert into the square groove 160, so that the sliding column 120 cannot be pulled out, and the locking mechanism 100 is locked and fixed to the drive shaft 300.

[0036] A circular groove 181 is provided in the side wall of the square plate 110. A sliding plate 182 is fixedly connected to the middle of the side wall of the sliding column 120. The sliding plate 182 is slidably connected in the circular groove 181. A second spring 183 is fixedly connected to one side of the sliding plate 182. The other end of the second spring 183 is fixedly connected to the side wall of the circular groove 181. The sliding column 120 drives the sliding plate 182 to slide, which compresses the second spring 183. When the pull column 140 is pulled to pull the inclined column 130 out of the square groove 160, the second spring 183 rebounds and drives the sliding column 120 to be pulled out from the first insertion hole 170, simplifying the disassembly operation steps.

[0037] The other end of the pull column 140 passes through the top surface of the square plate 110. A pull plate 141 is fixedly connected to the top surface of the pull column 140. The end of the sliding column 120 passes through the side wall of the square plate 110. A push plate 121 is fixedly connected to the end of the sliding column 120. The pull plate 141 facilitates pulling the pull column 140, and the push plate 121 blocks the end of the sliding column 120 outside the side wall of the square plate 110.

[0038] A baffle 190 is fixedly connected to the lower end of the side wall of the drive shaft 300. The top surface of the baffle 190 and the bottom surface of the square plate 110 are in contact. When the bottom of the square plate 110 and the baffle 190 are in contact, the sliding column 120 is aligned with the first insertion hole 170 to achieve quick alignment.

[0039] Working principle: After inserting the square plate 110 into the drive shaft 300 so that the bottom of the drive shaft 300 and the baffle 190 are in contact, the sliding post 120 is aligned with the first insertion hole 170. Pushing the push plate 121 causes the sliding post 120 to be inserted into the first insertion hole 170. The sliding post 120 causes the slide plate 182 to slide in the circular groove 181 and compresses the second spring 183. When the sliding post 120 is inserted, the inclined post 130 is pressed into the square hole at the top of the square plate 110 by the inclined surface of the inclined post 130, and the first spring 150 is compressed. When the sliding post 120 is inserted into place, the square groove 160 and the inclined post 130 are aligned. At this time, the first spring 150 rebounds. The inclined plate 130 slides out of the square hole at the top of the square plate 110 and inserts into the square groove 160, preventing the sliding column 120 from being pulled out. This locks the locking mechanism 100 and the drive shaft 300. When disassembly is required, pull the pull plate 141 to pull the pull column 140 to pull the inclined plate 130 out of the square groove 160. At this time, the second spring 183 rebounds and drives the slide plate 182 to slide out of the circular groove 181. The slide plate 182 drives the sliding column 120 to be pulled out of the first insertion hole 170. Finally, the square plate 110 can be pulled out of the drive shaft 300. The operation is simple and the disassembly and assembly are convenient. The integrated design avoids the loss of parts during disassembly and assembly, which would prevent the propeller from being fixed.

[0040] Please see Figure 1-5 As shown, this embodiment, based on the above embodiment, further includes:

[0041] The reinforcement mechanism 200 includes a screw 210, an upper round tube 220, an upper connecting rod 230, a lower round tube 240, a lower connecting rod 250, and a second insertion hole 260.

[0042] The screw 210 is threaded to the middle of the top surface of the drive shaft 300. The upper round tube 220 is rotatably connected to the upper end of the side wall of the screw 210. The two ends of the upper connecting rod 230 are rotatably connected to the side wall of the upper round tube 220 and the upper end of the lower connecting rod 250, respectively. The lower round tube 240 is fixedly connected to the top surface of the drive shaft 300. The lower end of the lower connecting rod 250 is rotatably connected to the side wall of the lower round tube 240. The second insertion hole 260 is opened in the middle of the side wall of the sliding column 120. The screw 210 is screwed into the middle of the top of the drive shaft 300, and the screw 210 rotates on the upper round tube 220. Simultaneously, the upper circular tube 220 slides down, causing the upper end of the upper connecting rod 230 to rotate and slide down at the same time, so that the other end of the upper circular tube 220 rotates inside the lower connecting rod 250 and moves outward, while simultaneously causing the upper end of the lower connecting rod 250 to move outward, and the lower end of the lower connecting rod 250 rotates on the side wall of the lower circular tube 240, so that the upper connecting rod 230 and the lower connecting rod 250 are fully opened and extend to both sides of the drive shaft 300 to lock the square plate 110, preventing the motor from rotating and causing the inclined column 130 to slide out of the square groove 160 due to vibration, thus causing the square plate 110 to fall off;

[0043] An upper side plate 221 is fixedly connected to the side wall of the upper round tube 220. An upper cylinder 222 is fixedly connected to the middle of the upper side plate 221. A rotating groove 251 is opened at the upper end of the lower connecting rod 250. A connecting column 252 is fixedly connected in the rotating groove 251. The two ends of the upper connecting rod 230 are rotatably connected to the upper cylinder 222 and the connecting column 252 respectively. When the upper round tube 220 slides down, it drives the upper end of the upper connecting rod 230 to rotate on the upper cylinder 222 and slide down with it, so that the lower end of the upper connecting rod 230 rotates on the connecting column 252 and moves outward.

[0044] A lower side plate 241 is fixedly connected to the side wall of the lower round tube 240. A lower cylinder 242 is fixedly connected to the middle of the lower side plate 241. The lower end of the lower connecting rod 250 is rotatably connected to the lower cylinder 242. The upper end of the lower connecting rod 250 moves outward with the lower end of the upper connecting rod 230, causing the lower end of the lower connecting rod 250 to rotate on the lower cylinder 242.

[0045] A rotating handle 211 is fixedly connected to the top of the screw 210. A threaded hole 270 is opened in the middle of the side wall of the first insertion hole 170. The bottom of the screw 210 is threaded into the threaded hole 270. The rotating handle 211 facilitates the rotation of the screw 210. When the upper connecting rod 230 and the lower connecting rod 250 are fully opened, the bottom of the screw 210 is screwed into the threaded hole 270.

[0046] Working principle: Rotating the rotating handle 211 drives the screw 210 to rotate. The screw 210 rotates on the upper round tube 220 and simultaneously drives it to slide down. The upper round tube 220 slides down, causing the upper end of the upper connecting rod 230 to rotate on the upper cylinder 222 and slide down as well. This causes the lower end of the upper connecting rod 230 to rotate on the connecting column 252 and move outward. The upper end of the lower connecting rod 250 moves outward along with the lower end of the upper connecting rod 230, causing the lower end of the lower connecting rod 250 to rotate on the lower cylinder 242. This fully opens the upper connecting rod 230 and the lower connecting rod 250, and then the bottom of the screw 210 is screwed into the threaded hole 270. The upper connecting rod 230 and the lower connecting rod 250 are fully opened and extend to both sides of the drive shaft 300, locking the square plate 110. This prevents the motor from rotating and causing the inclined column 130 to slide out of the square groove 160 due to vibration, which would cause the square plate 110 to fall off.

[0047] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
