The present invention belongs to the technical field of wing installation, and relates to an auxiliary device for installing the wing of an unmanned aerial vehicle. The present invention includes a bracket, a fixing mechanism, a protective plate, and a driving mechanism. A plurality of fixing mechanisms are arranged in parallel and spaced in sequence. When it is necessary to separate the suction cup from the wing, the first support shaft rotates clockwise around the first rotating shaft, so that the support plate moves downward while shifting to the right, and the support plate drives the second support shaft to rotate clockwise around the second rotating shaft, and the second support shaft causes one end of the support plate with the suction cup to flip downward around the first supporting shaft, so that the support plate changes from a vertical state to a horizontal state. In this way, the support plate is flipped to a horizontal state while moving downward, so that the suction cup is separated from the wing, and the fixing mechanism and the wing are prevented from generating motion interference, and collision damage to the wing is prevented. When the support plate is in a horizontal state, the suction cup fits with the protective plate, so as to prevent dust and impurities from falling into the suction cup, which is beneficial to protecting the suction cup.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1-Figure 9 As shown, the technical solution adopted by the present invention is as follows: an auxiliary device for installing the wing of a UAV includes a bracket 1, a fixing mechanism, a driving mechanism, and a protective plate 17.

[0029] There are a plurality of fixing mechanisms, the plurality of fixing mechanisms are parallel to each other and are sequentially spaced apart on the bracket 1 along the length direction of the bracket 1 .

[0030] The fixing mechanism includes a support plate 6, a first support shaft 5, and a second support shaft 10. The first support shaft 5 and the second support shaft 10 are both arranged horizontally, and the first support shaft 5 and the second support shaft 10 are perpendicular to the length direction of the bracket 1. The first support shaft 5 and the second support shaft 10 both penetrate the support plate 6 and are both rotatably matched with the support plate 6. Both ends of the first support shaft 5 are vertically fixedly connected with the first swing rod 4, and the end of each first swing rod 4 away from the first support shaft 5 is vertically fixedly connected with the first rotating shaft 2, and each first rotating shaft 2 is rotatably connected with the bracket 1. Both ends of the second support shaft 10 are vertically fixedly connected with the second swing rod 9, and the end of each second swing rod 9 away from the second support shaft 10 is fixedly connected with the second rotating shaft, and each second rotating shaft is rotatably connected with the bracket 1. Specifically, a plurality of hinge seats 8 are fixedly provided on the bracket 1, and the hinge seats 8 correspond to the second rotating shafts one by one, and the second rotating shafts are rotatably mounted on the corresponding hinge seats 8. The second rotating shaft is on the left side of the corresponding first rotating shaft 2. A plurality of suction cups 7 are fixedly provided at one end of the support plate 6 close to the second support shaft 10. The suction cup 7 is used to absorb the wings of the drone, thereby fixing the wings of the drone, making it easier to install the wings of the drone.

[0031] When the support plate 6 is in a vertical state, the suction cups 7 are vertically upward, and then the wing is placed on the plurality of suction cups 7, and the suction cups 7 adsorb and fix the wing. When the wing is installed, it is necessary to separate the fixing mechanism from the wing, such as Figure 7 As shown, the first swing arm 4 is in a vertical state. The first rotating shaft 2 is rotated, and the first swing arm 4 rotates clockwise around the axis of the first rotating shaft 2. The first swing arm 4 drives the first support shaft 5 to rotate clockwise around the axis of the first rotating shaft 2. The first support shaft 5 drives the support plate 6 to rotate clockwise around the axis of the first rotating shaft 2, so that the support plate 6 is shifted to the right and moves downward, so that the suction cup 7 is separated from the wing. The support plate 6 drives the second support shaft 10 to rotate the second support shaft 10 clockwise around the second rotating shaft. The second support shaft 10 causes the end of the support plate 6 with the suction cup 7 to flip downward around the first support shaft 5, so that the support plate 6 moves from a vertical state to a horizontal state. In this way, it is possible to avoid the movement interference between the fixing mechanism and the wing and cause collision damage to the wing.

[0032] A plurality of protective plates 17 are slidably connected in the bracket 1, and the protective plates 17 slide along the length direction of the bracket 1. The protective plates 17 correspond to the fixing mechanisms one by one, and the protective plates 17 cooperate with the corresponding suction cups 7. In this embodiment, the protective plates 17 are located on the left side of the corresponding fixing mechanisms. When the suction cups 7 are separated from the wings and are in a horizontal state, the suction cups 7 are adsorbed onto the corresponding protective plates 17 to prevent dust and impurities from falling into the suction cups 7 and affecting the next use.

[0033] Specifically, the bracket 1 is provided with multiple groups of slide grooves 19 at intervals, each group of slide grooves 19 includes two slide grooves 19, and the two slide grooves 19 in the same group are symmetrically arranged on both sides of the bracket 1. The multiple groups of slide grooves 19 correspond to the multiple protection plates 17 one by one, and the two ends of the protection plates 17 are fixed with slide plates 16, and the slide plates 16 are slidably arranged in the corresponding slide grooves 19. A spring 18 is fixedly connected between the slide plate 16 and one end wall of the slide groove 19.

[0034] The driving mechanism is arranged on the bracket 1 , and the driving mechanism drives the fixing mechanism to move and drives the protection plate 17 to slide along the bracket 1 at the same time.

[0035] The driving mechanism includes a U-shaped frame 11. The U-shaped frame 11 is slidably connected to the bracket 1, and the sliding direction of the U-shaped frame 11 is perpendicular to the axial direction of the second support shaft 10, that is, the U-shaped frame 11 slides along the length direction of the bracket 1. Specifically, the right end of the bracket 1 is rotatably connected to a threaded rod 13, and the axial direction of the threaded rod 13 is parallel to the sliding direction of the U-shaped frame 11. The U-shaped frame 11 is threadedly connected to the threaded rod 13. A rotating handle 14 is fixed to one end of the threaded rod 13 away from the bracket 1. The rotating handle 14 is rotated to rotate the threaded rod 13, thereby moving the U-shaped frame 11.

[0036] A plurality of rack groups are fixedly arranged at intervals on the U-shaped frame 11, and the plurality of rack groups correspond to a plurality of fixing mechanisms one by one. Each rack group includes two racks 12, and the two racks 12 in the same group are symmetrically arranged on both sides of the U-shaped frame 11. A gear 3 is coaxially fixedly arranged on each first rotating shaft 2, and the gear 3 cooperates with the corresponding rack 12. When the U-shaped frame 11 moves on the bracket 1, the rack 12 moves, thereby rotating the gear 3, and the gear 3 drives the first rotating shaft 2 to rotate, thereby moving the fixing mechanism. The rack 12 is above the gear 3. In the initial state, as Figure 5 As shown, there is a certain distance between the rack 12 and the corresponding gear 3 .

[0037] A plurality of push plate groups are fixedly arranged on the U-shaped frame 11 at intervals, and the plurality of push plate groups correspond to the plurality of slide grooves 19 one by one, and each push plate group includes two push plates 15, which are symmetrically arranged on both sides of the U-shaped frame 11, and each push plate 15 is slidably arranged in the corresponding slide groove 19, and the push plate 15 cooperates with the slide plate 16 in the corresponding slide groove 19. The push plate 15 is on the right side of the slide plate 16.

[0038] When the U-shaped frame 11 slides toward the direction close to the bracket 1, that is, toward the left, the push plate 15 pushes the slide plate 16, so that the slide plate 16 slides in the slide groove 19, so that the protective plate 17 moves toward the left, that is, moves away from the fixing mechanism, thereby disengaging the suction cup 7 from the protective plate 17, and at the same time the spring 18 is compressed. Then, as the U-shaped frame 11 moves, the driving mechanism turns the suction cup 7 upward, so that the suction cup 7 is in a vertical state. When the U-shaped frame 11 moves to the right, the squeezing of the push plate 15 is lost, and under the action of the spring 18, the protective plate 17 moves to the right, that is, toward the direction close to the fixing mechanism. At the same time, the U-shaped frame 11 drives the suction cup 7 to turn to the left, and when the support plate 6 is in a horizontal state, the suction cup 7 faces the corresponding protective plate 17, and then moves to the right with the protective plate 17, thereby making the protective plate 17 fit with the suction cup 7.

[0039] There is rotation damping between the first rotating shaft 2 and the bracket 1, that is, the first rotating shaft 2 will not rotate under the action of gravity of the fixing mechanism.

[0040] Working principle and process: In the initial state, the support plate 6 is in a horizontal state and the suction cup 7 faces the corresponding protective plate 17 and fits with the corresponding protective plate 17. Figure 5 As shown, the rack 12 is located on the right side of the corresponding gear 3 and has a certain distance from the corresponding gear 3. Under the action of the spring 18, the protective plate 17 fits with the suction cup 7 to prevent dust and impurities from falling into the suction cup 7, thereby protecting the suction cup 7.

[0041] When it is needed, the rotating handle 14 is rotated to move the U-shaped frame 11 to the left, that is, to the direction close to the bracket 1. The rack 12 and the push plate 15 move synchronously. Initially, the rack 12 gradually approaches the corresponding gear 3, and the push plate 15 pushes the slide plate 16 to make the slide plate 16 move to the left to overcome the elastic force of the spring 18. The slide plate 16 drives the protective plate 17 to move away from the corresponding fixing mechanism, so that the protective plate 17 is separated from the suction cup 7, and the spring 18 is further compressed. The protective plate 17 is kept away from the fixing mechanism to prevent the protective plate 17 from hindering the movement of the fixing mechanism.

[0042] As the U-shaped frame 11 moves to the left, when the rack 12 meshes with the gear 3, the rack 12 drives the gear 3 to rotate. Fig. 9In the direction shown, the rack 12 drives the gear 3 to rotate counterclockwise, thereby causing the first swing arm 4 and the first support shaft 5 to rotate counterclockwise around the first rotating shaft 2, and the first support shaft 5 drives the support plate 6 to rotate counterclockwise around the first rotating shaft 2, so that the support plate 6 moves upward while shifting to the left. The support plate 6 causes the second support shaft 10 and the second swing arm 9 to rotate counterclockwise around the second rotating shaft, and the second support shaft 10 gradually moves upward relative to the second rotating shaft. Then, the end of the support plate 6 equipped with the suction cup 7 gradually turns upward around the first support shaft 5, so that the support plate 6 moves from a horizontal state to a vertical state. When the support plate 6 is in a vertical state, the suction cup 7 is vertically upward. At this time, the wing can be installed on the suction cup 7, and the wing is fixed by the adsorption of the suction cup 7, which facilitates the installation of the wing on the drone. At this time, the rack 12 is meshed with the gear 3, so that the support plate 6 remains in a vertical state. The state at this time is shown in the suction cup 7.

[0043] After use, the rotating handle 14 is rotated in the opposite direction to move the U-shaped frame 11 to the right, that is, away from the bracket 1, and the rack 12 drives the gear 3 to rotate clockwise, and the gear 3 drives the first swing rod 4 and the first support shaft 5 to rotate clockwise around the first rotating shaft 2, and the first supporting shaft 5 drives the supporting plate 6 to rotate clockwise around the first rotating shaft 2, so that the supporting plate 6 deviates to the right and moves downward, and the supporting plate 6 makes the second swing rod 9 and the second supporting shaft 10 rotate clockwise around the second rotating shaft, and the second supporting shaft 10 makes the end of the supporting plate 6 close to the suction cup 7 flip downward around the first supporting shaft 5, so that the supporting plate 6 changes from a vertical state to a horizontal state. In this way, the supporting plate 6 moves downward and flips at the same time, so that the suction cup 7 is separated from the wing, so as to avoid the fixing mechanism from interfering with the wing during the rotation process and prevent collision damage to the wing.

[0044] During the rightward movement of the U-shaped frame 11, the push plate 15 moves synchronously, and the push plate 15 gradually releases the pressure on the slide plate 16, so that the slide plate 16 slides to the right along the slide groove 19 under the action of the spring 18, and the protective plate 17 moves toward the direction close to the fixing mechanism. When the support plate 6 is in a horizontal state, the rack 12 is disengaged from the gear 3. Then the rotating handle 14 is continuously rotated to make the U-shaped frame 11 continue to move to the right, so that the protective plate 17 continues to move toward the direction close to the fixing mechanism, until the protective plate 17 is in contact with the suction cup 7. The device returns to the initial state.
