Description

Technical Field

[0001] This utility model relates to the field of wing technology, specifically to a drone wing. Background Technology

[0002] The wing of a drone is the core component of a fixed-wing drone. Its main function is to generate lift to support flight, while also providing stability and control. It is an unmanned aircraft controlled by radio remote control equipment and its own program control device. The wing generates lift to achieve flight and movement. However, conventional drones have wings fixed to the cantilever ends, taking up a large area when not in flight, which easily damages the wings. The wings cannot be folded and secured to reduce damage from automatic unfolding during transport. Furthermore, if the wings are damaged during flight after prolonged use, they are inconvenient to disassemble and replace individually. The wings are not fixed when unfolded, making them prone to rotation and deviation during flight, affecting flight stability. Utility Model Content

[0003] The purpose of this invention is to provide a drone wing to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A drone wing includes four wing assemblies, each wing assembly including symmetrical wing blades, the wing blades being mounted on an arm, a drive seat being provided at the top of the left end of the arm, a lower clamping plate being provided at the top of the drive shaft in the middle of the drive seat, an upper clamping plate being provided above the lower clamping plate, and wing blades for folding and adjustment being installed between the lower clamping plate and the upper clamping plate, all four wing assemblies being mounted on the fuselage; Support rods are provided on the outer wall of the machine near the four corners. The ends of the support rods are provided with slots, and the tops of the support rods are symmetrically provided with countersunk holes that communicate with the slots. A plate is provided at the right end of the arm corresponding to the slot. A second screw hole is provided at the top of the plate corresponding to the countersunk hole. A second fixing bolt is provided in the second screw hole. The wing blade tip is provided with a pivot post, and a storage groove is opened in the middle of the pivot post. A snap button is provided in the storage groove, and the top of the snap button protrudes from the top of the storage groove. A spring is provided inside the snap button.

[0005] Furthermore, the bottom of the drive seat is fixed to the end of the arm with screws, the drive shaft on the drive seat is coaxially connected to the motor output shaft inside the drive seat, and the top of the drive shaft is fixedly connected to the bottom of the lower clamping plate with screws.

[0006] In this invention, the motor is installed inside the drive housing to provide output power for the rotation of the drive shaft, and the drive shaft is connected to the lower clamping plate to achieve continuous rotation of the lower clamping plate.

[0007] Specifically, the lower clamping plate has symmetrically arranged fixing posts on its upper surface, the top of the fixing posts has a first screw hole, the upper clamping plate has an insertion hole corresponding to the fixing posts, and a first fixing bolt is provided above the insertion hole.

[0008] In this invention, the bottom of the fixing column and the upper surface of the lower clamping plate are integrally formed, the top of the fixing column is inserted into the insertion hole, and the first fixing bolt passes through the insertion hole and is threadedly connected to the first screw hole, so that the upper clamping plate and the lower clamping plate are fixed on the top of the fixing column, thereby increasing the stability of the installation.

[0009] It should be noted that the airfoil is rotatably connected to the lower clamping plate and the upper clamping plate via a pivot column. Two sets of limiting holes are symmetrically provided on the upper surface of the upper clamping plate near the pivot holes, and the two limiting holes are at a 90-degree angle to each other.

[0010] In this invention, the pivot hole facilitates the rotation of the airfoil between the lower and upper clamping plates. The two limiting holes fix the direction of the airfoil after rotation. When the airfoil rotates and is limited by the two adjacent limiting holes, the airfoil unfolds, facilitating rotation and providing lift. When the airfoil rotates and is limited by the two distant limiting holes, the airfoil folds and is stored, reducing the space occupied during transportation.

[0011] Furthermore, the snap button slides up and down in the storage groove, a limiting ring is provided at the bottom of the outer wall of the snap button, the top of the spring is fixedly connected to the top of the inside of the snap button, the bottom of the spring is fixedly connected to the bottom of the storage groove, and the outer diameter of the top of the snap button is adapted to the outer diameter of the limiting hole.

[0012] In this invention, the spring has elasticity and compresses the buckle button from the storage slot to the corresponding limiting hole, thereby fixing the wing's rotation, unfolding, or folding position. The limiting ring restricts the buckle button's movement in the storage slot, preventing it from detaching from the wing. When wing rotation is required, an external pressing tool is used to press the buckle button from the corresponding limiting hole into the storage slot, causing the spring to contract. Then, the corresponding wing is rotated to achieve the unfolding or folding operation.

[0013] It is worth adding that the insert plate and the arm are integrally formed, the width of the outer wall of the insert plate is adapted to the width of the inner wall of the slot, and the second fixing bolt passes through the countersunk hole and is threadedly connected to the second screw hole.

[0014] In this invention, the insert plate and the slot are inserted into each other and connected to the second screw hole through the second fixing bolt, so as to realize the combination and fixation of the machine arm and the support rod, thereby increasing the stability of the combined installation. The second fixing bolt can be removed to facilitate the separation and disassembly of the machine arm and the support rod.

[0015] In addition, the support rod and the machine body are integrally formed, and the motor inside the drive seat is electrically connected to the corresponding control switch inside the machine body through wires.

[0016] In this invention, the motor is started by activating the internal control switch of the fuselage, thereby enabling the corresponding lower clamping plate, upper clamping plate and airfoil to rotate in coordination.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model features symmetrical airfoils that, through the rotational cooperation of the pivot column and the upper and lower clamping plates, and the action of spring-loaded snap buttons, achieve the engagement of the airfoils with corresponding limiting holes, thereby enabling the airfoils to unfold or fold for storage, reducing the space occupied by the airfoils when not in use. Furthermore, the first fixing bolt is connected to the fixing column to achieve the combined fixation of the upper and lower clamping plates. The first fixing bolt can be removed, facilitating the disassembly and replacement of the airfoils and avoiding the waste of materials from replacing the entire unit.

[0018] 2. This utility model achieves the combination and fixation of the arm and the support rod by setting the arm to be inserted into the slot of the support rod on the body through the insertion plate, and the second fixing bolt passing through the countersunk hole and threadedly connected to the second screw hole. The removal of the second fixing bolt facilitates the disassembly and replacement of the arm. The motor inside the drive seat is matched to achieve the drive of the airfoil.

[0021] 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.

[0022] Please see Figures 1-7 This embodiment provides a technical solution: A drone wing includes four wing assemblies, each wing assembly including symmetrical wing blades 1, the wing blades 1 being mounted on an arm 3, a drive seat 2 being provided at the top left end of the arm 3, the bottom of the drive seat 2 being fixed to the end of the arm 3 by screws, the drive shaft on the drive seat 2 being coaxially connected to the motor output shaft inside the drive seat 2, and the top of the drive shaft being fixed to the bottom of the lower clamping plate 20 by screws.

[0023] In this invention, the motor is installed inside the drive base 2 to provide output power for the rotation of the drive shaft, and the drive shaft is connected to the lower clamping plate 20 to achieve continuous rotation of the lower clamping plate 20.

[0024] Furthermore, a lower clamping plate 20 is provided at the top of the drive shaft in the middle of the drive seat 2, and an upper clamping plate 21 is provided above the lower clamping plate 20. A wing blade 1 for folding adjustment is installed between the lower clamping plate 20 and the upper clamping plate 21. The fuselage 4 is installed on all four sets of wing components. Specifically, the upper surface of the lower clamping plate 20 is symmetrically provided with fixing posts 22, the top of the fixing posts 22 is provided with a first screw hole 220, the upper clamping plate 21 is provided with an insertion hole 211 corresponding to the fixing posts 22, and a first fixing bolt 212 is provided above the insertion hole 211.

[0025] In this utility model, the bottom of the fixing post 22 and the upper surface of the lower clamping plate 20 are integrally formed. The top of the fixing post 22 is inserted into the insertion hole 211, and the first fixing bolt 212 passes through the insertion hole 211 and is threadedly connected to the first screw hole 220, so that the upper clamping plate 21 and the lower clamping plate 20 are fixed on the top of the fixing post 22, thereby increasing the stability of the installation.

[0026] It should be noted that the wing blade 1 is rotatably connected to the lower clamping plate 20 and the upper clamping plate 21 via a rotating shaft column. Two sets of limiting holes 210 are symmetrically provided on the upper surface of the upper clamping plate 21 near the rotating shaft hole, and the two limiting holes 210 are at a 90-degree angle to each other.

[0027] In this invention, the pivot hole facilitates the rotation of the wing blade 1 between the lower clamping plate 20 and the upper clamping plate 21. The two limiting holes 210 fix the direction of the wing blade 1 after rotation. When the wing blade 1 rotates and is limited by the two adjacent limiting holes 210, the wing blade 1 unfolds, facilitating rotation and providing lift. When the wing blade 1 rotates and is limited by the two distant limiting holes 210, the wing blade 1 folds and is stored, reducing space occupied during transport.

[0028] Furthermore, support rods 40 are provided on the outer wall of the body 4 near the four corners. The end of the support rod 40 is provided with a slot 400, and the top of the support rod 40 is symmetrically provided with countersunk holes 401 that communicate with the slot 400. Secondly, a plate 30 is provided at the right end of the arm 3 corresponding to the slot 400. A second screw hole 300 is provided at the top of the plate 30 corresponding to the countersunk hole 401. A second fixing bolt 31 is provided in the second screw hole 300. Specifically, the insert plate 30 and the arm 3 are integrally formed. The width of the outer wall of the insert plate 30 is adapted to the width of the inner wall of the slot 400. The second fixing bolt 31 passes through the countersunk hole 401 and is threadedly connected to the second screw hole 300.

[0029] In this utility model, the insert plate 30 is inserted into the slot 400 and connected to the second screw hole 300 through the second fixing bolt 31, so as to realize the combination and fixation of the arm 3 and the support rod 40, thereby increasing the stability of the combined installation. The second fixing bolt 31 can be removed to facilitate the separation and disassembly of the arm 3 and the support rod 40.

[0030] It is worth adding that the end of the wing blade 1 is provided with a pivot column, and a storage groove 10 is opened in the middle of the pivot column. A latching button 11 is provided in the storage groove 10. The top of the latching button 11 protrudes from the top of the storage groove 10, and a spring 110 is provided inside the latching button 11.

[0031] Furthermore, the snap button 11 slides up and down in the storage groove 10. A limiting ring is provided at the bottom of the outer wall of the snap button 11. The top of the spring 110 is fixedly connected to the top of the inside of the snap button 11, and the bottom of the spring 110 is fixedly connected to the bottom of the storage groove 10. The outer diameter of the top of the snap button 11 is adapted to the outer diameter of the limiting hole 210.

[0032] In this invention, the spring 110 has elasticity and extensibility. The spring 110 presses the buckle button 11 from the storage groove 10 to the corresponding limiting hole 210, so as to realize the rotation and unfolding or folding and storage position of the wing blade 1. The limiting ring restricts the movement of the buckle button 11 in the storage groove 10 to prevent the buckle button 11 from detaching from the wing blade 1. When the wing blade 1 needs to be rotated, the buckle button 11 is pressed from the corresponding limiting hole 210 and stored in the storage groove 10 by an external pressing tool. The spring 110 contracts, and then the corresponding wing blade 1 is rotated to realize the unfolding or folding and storage operation.

[0033] In addition, the support rod 40 and the body 4 are integrally formed, and the motor inside the drive base 2 is electrically connected to the corresponding control switch inside the body 4 through wires.

[0034] In this invention, the motor is started by the internal control switch of the fuselage 4, which in turn enables the corresponding lower clamping plate 20, upper clamping plate 21 to rotate in coordination with the wing blade 1.

[0035] In this embodiment, when the drone wing is in use, firstly, the drive seat 2 with the motor is combined and fixed with the arm 3, and the drive shaft is combined and fixed with the lower clamping plate 20. Then, the buckle button 11 with the spring 110 is slidably inserted into the storage groove 10 on the wing blade 1. Then, the wing blade 1 is rotatably inserted into the upper clamping plate 21 and the lower clamping plate 20 through the rotating shaft column. The upper clamping plate 21 and the lower clamping plate 20 are inserted into the insertion hole 211 through the fixing post 22. The first fixing bolt 212 passes through the insertion hole 211 and is threadedly connected to the first screw hole 220, so that the upper clamping plate 21 and the lower clamping plate 20 are tightly fitted and fixed, and the position of the two wing blades 1 is fixed. Then, the arm 3 is inserted into the slot 400 on the support rod 40 through the insertion plate 30, and is threadedly connected to the second screw hole 300 through the countersunk hole 401 through the second fixing bolt 31. When the wing blade 1 needs to be folded and stored, the buckle button 11 is engaged in the corresponding mutually spaced limiting holes 210. The two wing blades 1 on the same lower clamping plate 20 are folded and stored, and the wing blade 1 and the arm 3 are arranged horizontally. When the wing blade 1 needs to be unfolded, the buckle button 11 in the mutually spaced limiting holes 210 is pressed and stored in the storage groove 10 by an external pressing tool. The spring 110 is pressed and contracted. Then the wing blade 1 is rotated so that the buckle button 11 passes out from the two mutually close limiting holes 210 and fixes the position of the unfolded wing blade 1. After prolonged use, if the wing blade 1 is damaged and needs to be replaced, the first fixing bolt 212 is removed to open the upper clamp 21 and remove the damaged wing blade 1. When the arm 3 is damaged and needs to be replaced, the second fixing bolt 31 is removed to allow the arm 3 to be replaced separately.
