Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a hangar for multi-rotor UAVs. Background Technology

[0002] With the large-scale application of multi-rotor drones in fields such as inspection and logistics, the development of supporting drone hangars, as the core infrastructure for realizing the automatic take-off, landing, storage, and transportation of drones, has attracted much attention. Existing drone hangars generally adopt a structural design that combines a parking platform with fixed supports, using mechanical limiting methods to ensure the stability of drones during transportation or storage.

[0003] In traditional solutions, a fixed support is installed on the landing platform, and the drone needs to land on the fixed support to achieve positioning and fixation. However, due to limitations in the accuracy of autonomous landing and environmental disturbances, drones often cannot land accurately on the first attempt in actual operations, requiring manual intervention for position calibration and mechanical locking, thus reducing operational efficiency.

[0004] Therefore, further, existing technology pre-installs a fixed bracket on the bottom of the drone. After the drone lands on the platform, the bracket is laterally clamped and fixed by a push plate on the drive platform. Then, the hangar cover is flipped over to complete the return and storage of the drone.

[0005] However, in actual use, this type of drone hangar requires the bracket to be clamped after the drone has landed, and the protective arc cover on the top of the hangar to be closed after the limit is completed. This results in a break in the operation process and prolongs the overall storage time. Utility Model Content

[0006] The purpose of this utility model is to provide a hangar for multi-rotor drones to solve the technical problems of fragmented processes and low storage efficiency caused by distributed operation clamping actions and cover flipping actions in the prior art.

[0007] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0008] A multi-rotor drone hangar includes an outer shell, within which a parking platform for parking drones is installed. Above the parking platform is a push plate assembly for clamping and limiting the drone. Below the parking platform is a main shaft, which is connected to the push plate assembly via a synchronization structure. A rotating arc cover is fixedly mounted on the main shaft. A drive source for providing rotational torque is connected to either end of the main shaft. The axial rotation of the main shaft synchronously drives the push plate assembly to clamp and limit the drone and causes the rotating arc cover to cover the parking platform.

[0009] As a preferred embodiment of this utility model, the two ends of the main shaft are rotatably connected to the inner side of the outer housing, and any end of the main shaft passes through the outer housing and is connected to a drive motor for providing rotational torque, the drive motor being fixed to the outer wall of the outer housing.

[0010] As a preferred embodiment of the present invention, the synchronization structure includes a drive gear disposed inside the outer housing, the drive gear being fixedly sleeved at both ends of the main shaft, and a follower rack slidably mounted on the outer housing meshing with the upper and lower ends of the drive gear.

[0011] As a preferred embodiment of the present invention, the push plate assembly includes two parallel horizontal push plates. One of the horizontal push plates extends downward at both ends and is connected and fixed to two follower racks located at the upper end of the drive gear. The other horizontal push plate is connected and fixed at both ends to two follower racks located at the lower end of the drive gear. When the main shaft rotates, the two horizontal push plates move in opposite directions.

[0012] As a preferred embodiment of the present invention, the push plate assembly further includes two parallel longitudinal push plates. The longitudinal push plates are arranged perpendicularly to the transverse push plates and are not located on the same horizontal plane. The transverse push plate drives the longitudinal push plates to slide synchronously through the linkage structure to clamp and limit the UAV on the parking platform from four sides.

[0013] As a preferred embodiment of the present invention, the linkage structure includes an isosceles trapezoidal block connected to two longitudinal push plates that are far apart from each other on one side wall, and a right-angled trapezoidal block with one end abutting against the inclined section of the isosceles trapezoidal block is connected to the transverse push plate.

[0014] As a preferred embodiment of this utility model, the outer shell has two inner sidewalls opposite to each other with grooves, and the end of the longitudinal push plate is slidably disposed in the grooves; the grooves are provided with a reset device for resetting the longitudinal push plate when no external force is applied.

[0015] As a preferred embodiment of the present invention, the reset device includes a baffle fixedly disposed in the middle of the slide groove, and reset springs are connected to both sides of the baffle. The other end of the reset springs is fixedly connected to the longitudinal push plate.

[0016] As a preferred embodiment of this utility model, flexible columns are fixedly provided at the center of both the transverse push plate and the longitudinal push plate, which are positioned towards the center of the parking platform.

[0017] As a preferred embodiment of the present invention, a second sliding groove is provided at the bottom of the outer housing, and the follower rack located below the drive gear is slidably disposed in the second sliding groove;

[0018] A third sliding groove is provided on the side wall of the outer housing, and the follower rack located above the drive gear is slidably disposed in the third sliding groove through the mounting component.

[0019] Compared with the prior art, this utility model has the following advantages:

[0020] This invention features a rotating arc cover on the main shaft and a push plate connected by a drive gear and a follower rack. When the main shaft rotates axially, it can simultaneously drive the horizontal and vertical push plates to move. Thus, while closing the rotating arc cover, the horizontal and vertical push plates clamp and limit the drone, thereby improving the drone hangar's storage time for drones and reducing operation steps.

[0028] 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.

[0029] like Figure 1 and Figure 4 As shown, this utility model provides a multi-rotor drone hangar, including an outer shell 1, which can be fixed on the ground by a fixed bracket. A parking platform 2 for parking drones is fixedly installed inside the outer shell 1. A push plate assembly for clamping and limiting the drone is installed above the parking platform 2. A main shaft 3 is rotatably installed below the parking platform 2, with both ends of the main shaft 3 rotatably connected to the inner side of the outer shell 1. One end of the main shaft 3 passes through the outer shell 1 and is connected to a drive source 18 for providing rotational torque. The drive source can be a drive motor, which is fixed to the outer wall of the outer shell 1. A rotating arc cover 4 is fixedly installed on the main shaft 3, and the rotating arc cover 4 is fixedly connected to both ends of the main shaft 3 by a two-point connection. The drive motor drives the main shaft 3 to rotate axially, causing the rotating arc cover 4 to cover the parking platform 2. Furthermore, the main shaft 3 is connected to the push plate assembly through a synchronous structure. When the main shaft 3 rotates and drives the rotating arc cover 4 to cover the parking platform 2, the main shaft 3 drives the push plate assembly to clamp and limit the drone through the synchronous structure, so as to form the main shaft 3 synchronously drives the push plate assembly to clamp and limit the drone and drive the rotating arc cover 4 to cover the parking platform 2.

[0030] like Figure 2 As shown, the synchronization structure includes a drive gear 5 disposed inside the outer housing 1. The drive gear 5 is fixedly sleeved at both ends of the main shaft 3. The upper and lower ends of the drive gear 5 are engaged with a follower rack 6 that is slidably mounted on the outer housing 1.

[0031] The bottom of the outer housing 1 is provided with a second slide groove 16, and the follower rack 6 located below the drive gear 5 is slidably disposed in the second slide groove 16.

[0032] Since the follower rack 6 is meshed with the drive gear 5, and a second slide groove 16 is provided at the bottom of the outer housing 1, the follower rack 6 located below the drive gear 5 is slidably disposed in the second slide groove 16, which can limit the follower rack 6, thereby making it more stable and better adaptable during movement.

[0033] Similarly, a third slide groove 17 is provided on the side wall of the outer housing 1, and the follower rack 6 located above the drive gear 5 is slidably disposed in the third slide groove 17 through the mounting component.

[0034] like Figure 1 As shown, the pusher assembly includes two parallel horizontal pushers 7. One horizontal pusher 7 has its two ends extending downwards and connected to two follower racks 6 located above the drive gear 5. The other horizontal pusher 7 has its two ends connected to two follower racks 6 located below the drive gear 5. When the main shaft 3 rotates, the two horizontal pushers 7 move in opposite directions. The two horizontal pushers 7 clamp and limit the UAV on the landing platform 2 by sliding towards each other. The main shaft 3 rotates axially, driving four follower racks 6 to move synchronously through the drive gears 5 at both ends. The four follower racks 6 are connected to the two horizontal pushers 7 respectively, thus causing the two horizontal pushers 7 to move towards each other, clamping the UAV from two directions on the landing platform 2.

[0035] Furthermore, the pusher assembly also includes two parallel longitudinal pushers 8, which are perpendicular to the transverse pusher 7 and not located on the same horizontal plane. The transverse pusher 7 drives the longitudinal pusher 8 to slide synchronously through the linkage structure 9 to clamp and limit the UAV on the parking platform 2 from four sides.

[0036] Therefore, when the main shaft 3 rotates, its own rotation drives the rotating arc cover 4 to rotate and cover the platform 2. At the same time, the rotation of the main shaft 3 drives the horizontal push plate 7 to move through the drive gear 5 and the follower rack 6. The movement of the horizontal push plate 7 drives the vertical push plate 8 to move relative to each other through the linkage structure 9, thus forming a clamping grip on the drone from four directions. During the closing process of the rotating arc cover 4, the drone is clamped synchronously.

[0037] Among them, such as Figure 2 As shown, the linkage structure 9 includes an isosceles trapezoidal block 11 connected to two longitudinal push plates 8 on opposite side walls, and a right-angled trapezoidal block 10 connected to the transverse push plate 7, one end of which rests on the inclined section of the isosceles trapezoidal block 11.

[0038] like Figure 2 As shown, when the horizontal push plate 7 moves, the two right-angled trapezoidal blocks 10 on the horizontal push plate 7 will move towards each other. The inclined surfaces of the right-angled trapezoidal blocks 10 are used to press the inclined surfaces of the isosceles trapezoidal blocks 11, thereby pushing the longitudinal push plate 8 to move, forming the two longitudinal push plates 8 moving towards each other.

[0039] Furthermore, such as Figure 3 As shown, to improve the reciprocating cycle of the longitudinal push plate 8, first grooves 12 are provided on the two opposing inner sidewalls of the outer housing 1, and the ends of the longitudinal push plate 8 are slidably disposed in the first grooves 12. A reset device is provided in the first grooves 12 to reset the longitudinal push plate 8 when no external force is applied.

[0040] The reset device includes a baffle 13 fixedly installed in the middle of the first slide 12, and reset springs 14 connected to both sides of the baffle 13. The other end of the reset springs 14 is fixedly connected to the longitudinal push plate 8.

[0041] When the horizontal push plate 7 pushes the vertical push plate 8 to move through the right-angled trapezoidal block 10, the vertical push plate 8 will push the return spring 14 in the first slide groove 12 to compress it. When the main shaft 3 is rotated in the opposite direction to open the rotating arc cover 4, the vertical push plate 8 will move in the opposite direction to open under the rebound force of the return spring 14, thus unlocking the drone.

[0042] Furthermore, in actual operation, when a multi-rotor drone lands in a hangar, traditional clamping devices typically hold the support frame at the bottom of the drone, with the fixed support connected to the drone's handle, forming an indirect restraint. However, this connection method lacks restraint points on the drone body, making the drone, with its high center of gravity, prone to swaying and tipping over when placed in the hangar. Therefore, this invention features flexible posts 15 fixedly installed at the center of both the horizontal push plate 7 and the vertical push plate 8, pointing towards the center of the landing platform 2. In practical use, the flexible posts 15 are inserted between two adjacent rotors of the multi-rotor drone, forming abutment against the drone body and providing restraint, thereby improving the overall restraint capability.

[0043] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
