Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] Example

[0026] like Figure 1-5 This embodiment provides a drone hangar, including a hangar frame 1. Universal wheels are installed at the four corners of the bottom of the hangar frame 1. An ejection structure 2 is provided at the bottom of the hangar frame 1. The ejection structure 2 includes slide rails 21 installed on the left and right sides inside the hangar frame 1. A parking platform 4 is fixed between the inner rails of the left and right slide rails 21. A drone centering structure 3 is provided on the parking platform 4.

[0027] The lower side edge of the parking platform 4 is fixed with a platform frame 41 by bolts. The left and right sides of the parking platform 4 are fixed with mounting plates a37 by bolts. The mounting plates a37 are fixed to the platform frame 41 by bolts. The inner rails of the two slide rails 21 are fixed to the outer sides of the two mounting plates a37 respectively. The outer rails of the two slide rails 21 are fixed to the bottom left and right sides of the hangar frame 1 by corner brackets 28 and mounting plates b27.

[0028] The ejection structure 2 also includes a stepper motor 22 and a drive shaft 23 installed at the bottom rear side inside the hangar frame 1. Bearing seats are provided on both sides of the drive shaft 23. Synchronous pulleys 24 are fixedly installed in the middle and at both ends of the drive shaft 23. The synchronous pulley 24 in the middle of the drive shaft 23 is connected to the output shaft of the stepper motor 22 via a synchronous belt a, thereby causing the stepper motor 22 to drive the drive shaft 23 to rotate. The synchronous pulleys 24 at both ends of the drive shaft 23 are connected to mounting plates a37 on both sides of the parking platform 4 via synchronous belts b241. A synchronous belt clamping plate 25 for connecting the synchronous belt b241 is provided at the rear end of the mounting plate a37. During the rotation of the synchronous pulleys at both ends of the drive shaft 23, the meshing synchronous belt b241 will drive the mounting plate a37 and the parking platform 4 fixed on the mounting plate a37 to move back and forth in the front-rear direction. A driven synchronous pulley of the synchronous belt b241 is provided on the lower side of the front end of the mounting plate b27.

[0029] A proximity switch baffle 26 is installed at the rear end of the mounting plate a37 on the right side of the parking platform 4, and proximity sensors 29 are installed at both ends of the mounting plate b27 on the right side of the hangar frame 1. When the proximity switch baffle 26 approaches the proximity sensor 29, it will control the stepper motor 22 to stop rotating.

[0030] The UAV centering structure 3 includes two X-direction motion motors 31, two Y-direction motion motors 32, two X-direction stop bars 33, and two Y-direction stop bars 34. The two X-direction motion motors 31 are symmetrically installed at the left and right ends of the landing platform 4, and the two Y-direction motion motors 32 are symmetrically installed at the front and rear ends of the landing platform 4. Both X-direction motion motors 31 and Y-direction motion motors 32 are identical dual-output shaft motors. The output shafts at both ends of the two dual-output shaft motors are connected to ball screw sets 35 via couplings. The two X-direction stop bars 33 are symmetrically arranged on the front and rear sides of the landing platform 4, and the Y-direction stop bars 34 are symmetrically arranged on the left and right sides of the landing platform 4, with the Y-direction stop bars 34 located above the X-direction stop bars 33. The two ends of the X-direction stop bars 33 are respectively fixed to the nuts of the ball screw sets 35 on the left and right sides, and the two ends of the Y-direction stop bars 34 are respectively fixed to the nuts of the ball screw sets 35 on the front and rear sides.

[0031] The Y-direction stop lever 34 is provided with a charging contact 38. The charging contact can make contact with the contact of a specific drone modification part to complete the charging of the drone.

[0032] The ball screw assembly 35 has an encoder 36 installed at the end of the screw. When the motor rotates, driving the screw to rotate, the encoder rotates synchronously to record the rotation position. When the set position is reached, the motor stops rotating.

[0033] The hangar frame 1 has a hangar door 5 hinged to its front end. The lower end of the hangar door 5 is hinged to the hangar frame 1. Electric push rods 6 are hinged to the top left and right ends of the hangar frame 1, with the push rod ends of the electric push rods 6 hinged to the left and right ends of the hangar door 5. When the extension structure 2 retracts the UAV from the parking platform 4 into the hangar frame 1, the electric push rods 6 rotate the hangar door 5, thereby closing the hangar door 5.

[0034] The working principle of this utility model is as follows: the hangar frame supports the entire system. The push-out structure is completed using linear slide rails, stepper motors, and synchronous belt drives. The stepper motor drives the drive shaft to rotate, and synchronous pulleys are installed at both ends of the drive shaft. Power is transmitted to the parking platform through the synchronous belt. The parking platform is fixed on the linear slide rails, allowing the parking platform to move back and forth in the horizontal direction. The drone centering structure consists of four centering motors, eight lead screws, four centering stops, and other fixing components. The lead screws, driven by the stepper motors, complete the movement in both the X and Y axes to achieve the centering operation of the drone. In addition, charging contacts are installed on the two centering stops on the X-axis, which can contact the contacts of specific drone modification parts to complete the charging of the drone. The drone centering structure ensures that the various structural components of the drone do not collide with the hangar frame when the push-out structure retracts the drone into the hangar. The hangar door is opened and closed by an electric push rod. The electric push rod can retract back and forth under the action of a controller, causing the door to rotate. Hall switches are installed before and after the ejection structure. When the ejection structure is extended to the set position, the Hall switch is triggered to stop it. Similarly, when the ejection structure is retracted to the designated position, the Hall switch is triggered to stop it in place. The UAV centering structure uses an encoder to determine the position of the centering push rod. When the motor rotates, the encoder rotates synchronously to record the rotation position. When the set position is reached, the motor stops rotating.
