Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV wing protection structure. Background Technology

[0002] As a device with flexible flight and remote control capabilities, drones have been widely used in many fields such as aerial photography and surveying, agricultural plant protection, power line inspection, and logistics transportation. However, as the core component for generating lift, the structural integrity of the wing directly affects the drone's flight safety and service life. In actual use and storage, the wing faces multiple risks of damage, and existing protective measures have significant limitations.

[0003] Even when not in flight, the storage and transportation of drones can still pose a threat to their wings. Traditional drone wings are mostly fixed structures, and their large size when unfolded makes them prone to collisions with other objects due to space constraints during storage, resulting in damage to the drone wings.

[0004] In response to the technical problem that traditional drone wings are mostly fixed structures and have a large volume when unfolded, making them prone to collisions with other objects, this application proposes a drone wing protection structure. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of traditional drone wings, which are mostly fixed structures and have a large volume when unfolded, making them prone to collisions with other objects. The proposed invention is a drone wing protection structure that folds up the main body of the wing, reducing the overall volume of the drone wing and preventing the drone body from being easily damaged by collisions when not in use. Furthermore, the folded size is reduced, making it easier for users to carry in a backpack. The protective shell also protects the folded wing body from direct collisions, compression, or scratches from external objects during transportation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drone wing protection structure, comprising a drone body, bidirectional motors fixedly connected to the left and right sides of the inner wall of the drone body, rotating shafts fixedly connected to the front and rear driving ends of the bidirectional motors, and turntables fixedly connected to the opposite ends of the rotating shafts, the outer wall of the turntables being rotatably connected to the inner wall of the drone body, the turntables being connected to the wing body via a folding assembly, protective shells provided on the front and rear sides of the drone body, control rods slidably connected to the upper and lower sides of the inner wall of the protective shells, the control rods being connected to the drone body via a snap-fit ​​assembly.

[0007] Furthermore, the folding assembly includes two fixed blocks fixedly connected to opposite ends of the turntables on the front and rear sides, with a connecting shaft rotatably connected to the inner wall of the fixed blocks, and the inner wall of the wing body fixedly connected to the outer wall of the connecting shaft.

[0008] Furthermore, a first bevel gear is fixedly connected to the outer wall of the connecting shaft, and a second bevel gear is meshed with the outer wall of the first bevel gear. A fixed shaft is fixedly connected to one end of each of the front and rear sides of the second bevel gear.

[0009] Furthermore, the fixed shaft penetrates the inner wall of the turntable, and a support rod is fixedly connected to the outer wall of the fixed shaft. The outer wall of the support rod is fixedly connected to the inner wall of the UAV body.

[0010] Furthermore, the inner wall of the turntable is provided with a movable groove, and the support rod is located on the inner wall of the movable groove.

[0011] Furthermore, the snap-fit ​​assembly includes snap-fit ​​blocks fixedly connected to opposite ends of the control rods on the upper and lower sides. The outer wall of the snap-fit ​​block is slidably connected to the inner wall of the protective shell. Two snap-fit ​​slots are opened on the inner walls of the front and rear sides of the drone body, and the snap-fit ​​block engages with the snap-fit ​​slots.

[0012] Furthermore, springs are fixedly connected to one end of each of the upper and lower side blocks, and the other end of each spring is fixedly connected to the inner wall of the protective shell.

[0013] Furthermore, two positioning rods are fixedly connected to opposite ends of the protective shells on both the front and rear sides, and two positioning slots are opened on both the front and rear sides of the drone body, with the positioning rods matching the shape of the positioning slots.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the turntables on both sides are driven to rotate by a bidirectional motor, so that the main body of the wing rotates and folds close to the outer wall of the drone body, thereby folding the main body of the wing, reducing the overall volume of the drone wing, avoiding the drone body from being easily damaged by collisions due to its large size when not in use, and the reduced volume after folding makes it easy for users to put into their backpacks for carrying.

[0015] 2. In this utility model, the protective shell is placed on the front and rear sides of the drone body to protect the folded wing body, avoiding direct collision, squeezing or scratching of the wing by external objects during transportation, thereby improving transportation safety and reducing transportation loss rate.

Detailed Implementation

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 This utility model provides an embodiment of a drone wing protection structure, comprising a drone body 1, bidirectional motors 2 fixedly connected to the left and right sides of the inner wall of the drone body 1, rotating shafts 3 fixedly connected to the front and rear driving ends of the bidirectional motors 2, turntables 4 fixedly connected to opposite ends of the rotating shafts 3, the outer wall of the turntables 4 rotatably connected to the inner wall of the drone body 1, two fixing blocks 5 fixedly connected to opposite ends of the front and rear turntables 4, connecting shafts 6 rotatably connected to the inner walls of the fixing blocks 5, the inner wall of the wing body 7 fixedly connected to the outer wall of the connecting shafts 6, a first bevel gear 8 fixedly connected to the outer wall of the connecting shafts 6, a second bevel gear 9 meshing with the outer wall of the first bevel gear 8, a fixing shaft 10 fixedly connected to opposite ends of the second bevel gears 9 on both the front and rear sides, the fixing shaft 10 penetrating the inner wall of the turntables 4, a support rod 11 fixedly connected to the outer wall of the fixing shaft 10, the outer wall of the support rod 11 fixedly connected to the inner wall of the drone body 1, a movable groove 12 is opened in the inner wall of the turntables 4, and the support rod 11 is located in the inner wall of the movable groove 12.

[0020] Specifically, the inner wall of the turntable 4 is provided with a movable groove 12. When the turntable 4 rotates, the movable groove 12 will move on the outer wall of the support rod 11 to prevent the support rod 11 from getting stuck on the inner wall of the turntable 4. The second bevel gear 9 is fixed to the inner wall of the drone body 1 through the fixed shaft 10 and the support rod 11, so it does not move relative to the wing body 7. The bottom end of the drone body 1 is fixedly connected to the front and rear sides of the bottom, so that the drone body 1 is supported on the ground when it lands.

[0021] Reference Figure 4 and Figure 5 The drone body 1 has protective shells 13 on both the front and rear sides. Control rods 19 are slidably connected to the upper and lower sides of the inner wall of the protective shell 13. A locking block 16 is fixedly connected to one end of the upper and lower control rods 19. The outer wall of the locking block 16 is slidably connected to the inner wall of the protective shell 13. Two slots 17 are opened on the inner walls of both the front and rear sides of the drone body 1. The locking block 16 engages with the slots 17. A spring 18 is fixedly connected to one end of the upper and lower locking blocks 16. The other end of the spring 18 is fixedly connected to the inner wall of the protective shell 13. Two positioning rods 14 are fixedly connected to one end of the front and rear sides of the protective shell 13. Two positioning grooves 15 are opened on both the front and rear sides of the drone body 1. The positioning rods 14 and positioning grooves 15 are matched in shape.

[0022] Specifically, storage slots are provided on both the left and right sides inside the protective shell 13. The folded wing body 7 is located in the storage slots. The control lever 19 is flush with the protective shell 13. If the square box control lever 19 is accidentally pressed, the protective shell 13 has notches on both sides corresponding to the control lever 19, so that fingers can be inserted into the protective shell 13 to press the control lever 19.

[0023] Working principle: When the main body 1 of the drone is not in use, the bidirectional motor 2 can be started. The bidirectional motor 2 drives the rotating shafts 3 on both sides to rotate, which in turn drives the turntable 4 to rotate, thereby driving the fixed block 5 to rotate. The fixed block 5 then drives the wing body 7 to rotate through the connecting shaft 6, turning the wing body 7 from a horizontal state to a vertical state. When the connecting shaft 6 rotates, it drives the first bevel gear 8 to rotate, which in turn rotates around the second bevel gear 9, causing the first bevel gear 8 to rotate on its own axis. This, in turn, drives the connecting shaft 6 to rotate, causing the wing body 7 to flip, thus flipping the wing body 7 to fit snugly against the drone. On the outer wall of the human-machine body 1, the wing body 7 is folded and stored to reduce the exposed volume. Then, the positioning rod 14 on the protective shell 13 is aligned with the positioning groove 15 on the drone body 1 and inserted. At the same time, the control rods 19 on the upper and lower sides of the protective shell 13 are pressed, so that the control rods 19 drive the locking block 16 to move towards the middle of the protective shell 13 and compress the spring 18. When the positioning rod 14 is inserted into the positioning groove 15, the locking block 16 will be inserted into the locking groove 17. Then, the control rod 19 is released, and the spring 18 will rebound and the locking block 16 will move to both sides and engage with the locking groove 17, thereby fixing the protective shell 13 to the drone body 1.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
