Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicles (UAVs), and more specifically, to a quick-release structure for a UAV wing that is inserted into the wing bone. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously by an onboard computer, either completely or intermittently.

[0003] A search revealed an existing patent (application number: CN201811604046.9) disclosing a drone wing, comprising a turntable and blades. A rotating shaft is fixedly connected to one end of the blade near the turntable. An insertion hole is provided on the turntable, and the rotating shaft is rotatably connected to the insertion hole. The rotating shaft is positioned along the length of the blade, and the central axis of the insertion hole is perpendicular to and intersects the central axis of the turntable. Two blades are located on opposite sides of the turntable, lying on the same plane with an included angle of 180 degrees. The blades can be rotatably connected to the turntable via the rotating shaft, adjusting the tilt angle between the upper surface of the blade and the horizontal plane. In windy conditions, the blades can be rotated to reduce the angle between the upper surface of the blade and the horizontal plane, appropriately increasing the rotational speed of the blades. This reduces vibration and makes the drone's flight more stable while maintaining a constant lift for the drone. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing drone wings do not have a quick connection and disassembly function. During drone use, the wings are prone to damage. After the wings are damaged, they need to be quickly removed and replaced with new ones, which is inconvenient for outdoor maintenance and replacement work.

[0005] Therefore, a quick-release structure for UAV wings that is inserted into the wing bone is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a quick-release structure for a drone wing that is inserted into the wing bone to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick-release structure for a drone wing that is inserted into a wing bone, comprising a drone body, four sets of symmetrically arranged wing bones connected to the outer side of the drone body, and a wing bone folding connecting block connected to the wing bone and the drone body via a connecting shaft, and a wing connecting block provided at the end of the wing bone away from the wing bone folding connecting block, a wing drive motor connected to the bottom of the wing connecting block, and a signal receiver provided at the bottom of the wing drive motor;

[0008] The wing connecting block is provided with a drone wing, and the outer side of the drone wing is provided with two sets of symmetrical wing blades. The bottom of the drone wing is provided with a quick-connect block, and the quick-connect block is inserted into the wing connecting block.

[0009] Preferably, a position indicator label is provided on the top of the wing bone folding connecting block, and a positioning indicator label is provided at the top center of the UAV wing.

[0010] Preferably, the quick-connect block has two sets of symmetrical fixed limiting clamps on both sides of its bottom. The bottom of each fixed limiting clamp has a fixed protrusion that bends inward, and a first limiting protrusion is provided between the two sets of fixed limiting clamps.

[0011] Preferably, the wing connecting block is provided with a quick-connect hole that fits into the quick-connect connecting block, the quick-connect hole is provided with a fixing slot, and the bottom of the quick-connect hole is provided with two sets of mutually symmetrical second limiting protrusions.

[0012] Preferably, the first limiting protrusion and the second limiting protrusion are symmetrical trapezoidal protrusions, and the second limiting protrusion is engaged with the fixing protrusion on the inner side of the fixing limiting fixture, and the first limiting protrusion is engaged with the fixing slot.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. Compared with the prior art, this quick-release structure for drone wings that is inserted into the wing bone can indicate the corresponding drone wing to be connected to the wing bone and can complete the quick insertion. When the drone wing is disassembled and installed, the drone wing is installed and disassembled through the quick-connect block. During installation, the corresponding position can be determined by the position indicator label on the wing bone folding connecting block and the positioning indicator label on the drone wing, and the quick-connect block is inserted into the quick-connect hole in the wing connecting block.

[0015] 2. Compared with the prior art, this quick-release structure for drone wings that is inserted into the wing bone can quickly fix the drone wing and prevent it from falling off the wing bone. After the quick-connect block is inserted into the wing connecting block, by pressing down and rotating the quick-connect block, the highest point of the fixing protrusion on the inner side of the fixing limit clamp is aligned with the lowest point of the second limiting protrusion on the side away from the drone wing. During the rotation, the fixing protrusion on the inner side of the fixing limit clamp rotates to fit against the second limiting protrusion. At this time, the first limiting protrusion and the fixing slot are engaged with each other. After the connection is completed, the fixing limit clamp and the fixing protrusion, as well as the first limiting protrusion and the fixing slot, are pressed together to fix the connection. At this time, the second limiting protrusion and the first limiting protrusion are engaged with each other, so that the wing connecting block and the quick-connect block are fixedly connected.

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.

[0023] As attached Figures 1 to 5 The diagram shows a quick-release structure for a drone wing that is inserted into a wing bone. It includes a drone body 1, four sets of symmetrical wing bones 2 connected to the outer side of the drone body 1, and a wing bone folding connecting block 21 connected between the wing bone 2 and the drone body 1 via a connecting shaft. A wing connecting block 24 is provided at the end of the wing bone 2 away from the wing bone folding connecting block 21. A wing drive motor 23 is connected to the bottom of the wing connecting block 24, and a signal receiver 22 is provided at the bottom of the wing drive motor 23.

[0024] The wing connecting block 24 is provided with a drone wing 3, and the outer side of the drone wing 3 is provided with two sets of symmetrical wing blades 31. The bottom of the drone wing 3 is provided with a quick-connect block 32, and the quick-connect block 32 is inserted into the wing connecting block 24.

[0025] Specifically: the wing bone 2 is connected to the drone body 1 through the wing bone folding connecting block 21, and the wing bone 2 can be folded and stored through the wing bone folding connecting block 21. The drone wing 3 is installed and removed from the wing connecting block 24 through the quick-connect connecting block 32. The drone body 1 is moved by the drone wing 3, and the wing fan blade 31 is driven to rotate by the wing drive motor 23. The driving action of the wing drive motor 23 can be received by the signal receiver 22.

[0026] In a preferred embodiment, a position indicator label 211 is provided on the top of the wing bone folding connecting block 21, and a positioning indicator label 33 is provided at the top center of the drone wing 3. Furthermore, since the wing blades 31 on the two adjacent drone wings 3 have different bending and tilting directions, it is necessary to determine the installation position during the installation process. During installation, the corresponding positions can be determined by the position indicator label 211 on the wing bone folding connecting block 21 and the positioning indicator label 33 on the drone wing 3.

[0027] In a preferred embodiment, the quick-connect block 32 has two sets of symmetrical fixing clamps 321 on both sides of its bottom. The bottom of the fixing clamp 321 has a fixing protrusion 3211 that bends inward, and a first limiting protrusion 322 is provided between the two sets of fixing clamps 321. Furthermore, the quick-connect block 32 is fixed in the wing connecting block 24 by the fixing clamps 321 and the first limiting protrusion 322.

[0028] In a preferred embodiment, the wing connecting block 24 is provided with a quick-connect hole 241 that fits into the quick-connect connecting block 32. The quick-connect hole 241 is provided with a fixing slot 2411, and the bottom of the quick-connect hole 241 is provided with two sets of mutually symmetrical second limiting protrusions 242. Furthermore, the quick-connect connecting block 32 is first inserted into the quick-connect hole 241 in the wing connecting block 24, and the fixing limiting clamp 321 is inserted between the two sets of second limiting protrusions 242.

[0029] In a preferred embodiment, the first limiting protrusion 322 and the second limiting protrusion 242 are symmetrical trapezoidal protrusions, and the second limiting protrusion 242 is engaged with the fixing protrusion 3211 on the inner side of the fixing limiting clamp 321, while the first limiting protrusion 322 is engaged with the fixing slot 2411. Furthermore, after the quick-connect block 32 is inserted into the wing connecting block 24, by pressing down and rotating the quick-connect block 32, the highest point of the fixing protrusion 3211 on the inner side of the fixing limiting clamp 321 is moved away from the second limiting protrusion 242 from the unmanned wing 341. The lowest point on the side is first aligned, and during the rotation, the fixing protrusion 3211 on the inner side of the fixing limit clamp 321 rotates to be in contact with the second limiting protrusion 242. At this time, the first limiting protrusion 322 and the fixing slot 2411 are engaged with each other. After the connection is completed, the fixing limit clamp 321 and the fixing protrusion 3211, as well as the first limiting protrusion 322 and the fixing slot 2411, are pressed together and fixed. At this time, the second limiting protrusion 242 and the first limiting protrusion 322 are in contact with each other, so that the wing connecting block 24 and the quick-connect connecting block 32 are fixedly connected.

[0030] The working process of this utility model is as follows: the wing bone 2 is connected to the drone body 1 through the wing bone folding connecting block 21, and the wing bone 2 can be folded and stored through the wing bone folding connecting block 21. The drone body 1 is moved by the drone wing 3, and the wing fan blade 31 is driven to rotate by the wing drive motor 23. The driving action of the wing drive motor 23 can be received by the signal receiver 22.

[0031] When it is necessary to disassemble and install the drone wing 3, the drone wing 3 can be installed and disassembled from the wing connecting block 24 through the quick-connect connector 32. During installation, the corresponding position can be determined by the position indicator label 211 on the wing bone folding connecting block 21 and the positioning indicator label 33 on the drone wing 3, and the quick-connect connector 32 can be inserted into the quick-connect hole 241 in the wing connecting block 24.

[0032] When the quick-connect block 32 is inserted into the wing connecting block 24, by pressing down and rotating the quick-connect block 32, the highest point of the fixing protrusion 3211 on the inner side of the fixing limit clamp 321 is aligned with the lowest point of the second limiting protrusion 242 on the side away from the UAV wing 3. During the rotation, the fixing protrusion 3211 on the inner side of the fixing limit clamp 321 rotates to fit against the second limiting protrusion 242. At this time, the first limiting protrusion 322 and the fixing slot 2411 are engaged with each other. After the connection is completed, the fixing limit clamp 321 and the fixing protrusion 3211, as well as the first limiting protrusion 322 and the fixing slot 2411, are pressed together and fixed. At this time, the second limiting protrusion 242 and the first limiting protrusion 322 are in contact with each other, so that the wing connecting block 24 and the quick-connect block 32 are fixedly connected.
