Description

Technical Field

[0001] The utility model relates to the field of unmanned aerial vehicles, and particularly relates to an unmanned aerial vehicle with a wing protection device. Background Art

[0002] Civil unmanned aerial vehicles refer to unpiloted aircraft that do not include aeromodels and do not perform official tasks such as military, police, and customs. These unmanned aerial vehicles are operated through radio remote control devices or self - contained program control devices, and have a wide range of application fields and important economic value. Common civil unmanned aerial vehicles include DJI unmanned aerial vehicles, etc. The wings of conventional unmanned aerial vehicles are directly exposed to the air without a protection structure. When flying, when the wings collide with branches, walls, birds or people, it is easy to cause wing damage and personal injury.

[0003] A Chinese patent with an application date of December 2, 2022 and a publication number of CN218839812U discloses a protection device for the wings of a DJI unmanned aerial vehicle, including the unmanned aerial vehicle. The left and right sides of the unmanned aerial vehicle are both equipped with front arms and rear arms. The top sides of the other ends of the front arms and rear arms are both equipped with propellers, and the bottom sides of the other ends of the front arms and rear arms are both equipped with landing gears. Lower protection parts are arranged on the bottom sides of the front arms and rear arms, and upper protection parts are arranged on the top sides of the front arms and rear arms. The left ends of the lower protection parts and the upper protection parts are fixedly connected together through fasteners, and the right ends of the lower protection parts and the upper protection parts are rotatably connected through a rotating shaft. The upper protection parts are each composed of two braided rings and an airbag ring. The middle parts of the outer walls of the upper protection parts are both sleeved with annular reinforcement rings, and the annular reinforcement rings are fixedly connected to the upper protection parts. The utility model provides a protection device for the wings of a DJI unmanned aerial vehicle, which can protect the wings in all directions, and is provided with a multi - level buffer and anti - collision structure, with better buffer and anti - collision effects and simple installation.

[0004] In this technical solution, the protection device is wrapped outside the wing, and air flow can pass through the holes on the protection device. Although the number of holes is large, when the wing rotates, the protection device will still cause a certain degree of blockage to the air flow, affecting the normal flight of the unmanned aerial vehicle, so further improvement can be made.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figures 1-5 shown, a drone with a wing protection device includes a drone body 1. Extension arms 2 are provided on both the left and right sides of the drone body 1. Wings 3 are provided at the top of the other ends of the extension arms 2. An arched sheet 4 is provided at the top of the drone body 1. A tray 5 is provided at the bottom of the drone body 1. The arched sheet 4 and the tray 5 are detachably installed. Covering plates 6 are integrally formed at the four corners of the tray 5. The covering plates 6 correspond to the extension arms 2 one by one, and the covering plates 6 are attached to the extension arms 2. The other ends of the covering plates 6 are movably connected to a protection component 7.

[0021] During use, U-shaped plates 501 are fixedly installed in the middle of the left and right sides of the tray 5. An insertion slot is formed between the U-shaped plate 501 and the side surface of the tray 5. The end of the arched piece 4 is inserted into the insertion slot. A first threaded hole 502 is formed through the center of the U-shaped plate 501 and penetrates through the tray 5. A jack 401 is formed through the side surface of the end of the arched piece 4. A first bolt 503 is threadedly connected in the first threaded hole 502, and the first bolt 503 passes through the jack 401. Thus, through the connection of the first bolt 503, the arched piece 4 and the tray 5 are detachably installed. After the arched piece 4 is connected to the tray 5, it is clamped on the drone body 1. In practice, the cross-section of the covering plate 6 is U-shaped, and the covering plate 6 fits on the bottom and the left and right sides of the extension arm 2. During assembly, the tray 5 fits on the drone body 1 from below, and the extension arm 2 is correspondingly inserted into the inside of the covering plate 6.

[0022] Specifically, the protection component 7 includes an upper ring 701 and a lower half ring 702. The radii of the upper ring 701 and the lower half ring 702 are both larger than the radius of the wing 3. The upper ring 701 is located directly above the wing 3, and the lower half ring 702 is located directly below the wing 3. Fixing columns 703 are evenly arranged between the upper ring 701 and the lower half ring 702. Thus, through the cooperation of the upper ring 701, the lower half ring 702, and the fixing columns 703, the wing 3 is protected from the side. And it is ensured that the air flow can smoothly pass through the gaps between the upper ring 701, the lower half ring 702, and the fixing columns 703. Three groups of connecting strips 704 are fixedly arranged in an array on the inner side of the lower half ring 702. One end of the inner side of the three groups of connecting strips 704 is fixedly installed with a fixing plate 705. The other end of the fixing plate 705 is fixedly installed with two sliding sleeves 706. Sliding rods 707 are fixedly installed on both sides of the free end of the sliding sleeve 706. Connecting pieces are arranged at both ends of the sliding rod 707, and the connecting pieces can be fixed on the covering plate 6 by bolts, so that the protection component 7 and the covering plate 6 are detachably installed. The sliding sleeve 706 is slidably connected to the sliding rod 707. A spring 708 is sleeved on the outer side of the sliding rod 707. One end of the spring 708 is fixedly installed on the covering plate 6, and the other end of the spring 708 is fixedly installed on the end of the sliding sleeve 706 away from the fixing plate 705. When the upper ring 701, the lower half ring 702, and the fixing columns 703 collide with an object from the side, due to the elasticity of the spring 708, the sliding sleeve 706 can slide along the sliding rod 707, and the assembly of the upper ring 701, the lower half ring 702, and the fixing columns 703 can move a short distance, preventing the upper ring 701, the lower half ring 702, and the fixing columns 703 from being damaged under the impact, and preventing the fragments generated after damage from contacting the wing 3 and causing damage to the wing 3.

[0023] A suspension bracket 504 is fixedly installed at the center of the bottom of the tray 5. Multiple holes are provided at the bottom of the suspension bracket 504, enabling the suspension bracket 504 to be connected to other items such as cameras. Lugs 505 are fixedly installed at the four corners of the bottom of the tray 5. Threaded holes two are provided on the side of the other end of the lugs 505. The lugs 505 are threadedly connected with bolts two 506. A support leg 507 is sleeved outside the bolt two 506. An installation hole is provided at one end of the support leg 507. The support leg 507 is sleeved outside the bolt two 506 through the installation hole. By screwing the bolt two 506, the distance between the bolt head of the bolt two 506 and the lug 505 is increased. At this time, the support leg 507 can rotate around the outside of the bolt two 506. By screwing the bolt two 506 again, the bolt head of the bolt two 506 is matched with the lug 505 to clamp and fix the support leg 507, inhibiting the rotation of the support leg 507. When no items such as cameras are suspended at the bottom of the suspension bracket 504, the support leg 507 can be rotated to a horizontal state, and the suspension bracket 504 and the support leg 507 are used as the base of the drone. When items such as cameras are suspended at the bottom of the suspension bracket 504, the support leg 507 can be rotated to a vertical state. When the drone is placed on the ground, the support leg 507 supports the drone and prevents the suspended camera from contacting the ground.
