Description

Technical Field

[0001] The present invention relates to a transfer mechanism for a drone apron, and particularly to a rotary transfer docking device for a drone apron. Background Art

[0002] In the operation of a rotary-wing drone airport, the scheduling and handling of the apron are important links to ensure the efficient operation of the drones. Traditional technologies mainly rely on the following methods:

[0003] Manual operation: Operators manually handle the apron, especially the modular apron that can weigh up to 10 kg. This method is inefficient, and during frequent handling, manual operation is prone to fatigue and errors, posing significant safety hazards, such as heavy object falling or personnel injury.

[0004] Fixed mechanical devices: Some drone airports use simple fixed fixtures or conveyor belts for apron transfer. These devices usually have a single design and lack flexibility, and cannot adapt to different sizes of aprons (such as changes in width or height). In addition, when transferring the apron from the lifting mechanism to the parking area or the ground trolley, fixed fixtures often require multiple steps and additional equipment cooperation, resulting in complex operation and low efficiency.

[0005] Limitations of existing automation solutions: Some automation devices rely on complex robotic arms or multi-axis robots. Although the degree of automation is improved, the cost is high and maintenance is difficult, which is not suitable for large-scale deployment. In addition, these solutions are generally not optimized for the special requirements of modular aprons in drone airports, such as rapid docking with ground logistics trolleys or adapting to changes in apron size. Summary of the Invention

[0006] The purpose of the present invention is to overcome the above-mentioned shortcomings and deficiencies of the prior art, and provide a rotary transfer docking device for a drone apron with a simple structure and high efficiency.

[0039] The rotating mechanism 200 includes a motor fixed substrate 208, a double-output shaft motor 201, a long shaft 204, a swing arm 207, and a long connecting rod assembly;

[0040] The double-output shaft motor 201 is installed in the middle of the motor fixed substrate 208, and a worm 202 is installed on the rotating shafts at both ends of the double-output shaft motor 201;

[0041] The long shaft 204 is fixed on the motor fixed substrate 208 through a bearing seat 205; a worm gear 203 is installed on the shaft rod of the long shaft 204 corresponding to the worm 202, and the worm gear 203 meshes with the worm 202;

[0042] There are two swing arms 207, which are respectively installed at both ends of the long shaft 204 through flanges 206. When the long shaft 204 rotates forward and backward, it drives the swing arms 207 to make reciprocating up and down swinging movements.

[0052] The following further describes the present invention by listing application scenarios, such as Figure 4 .

[0053] 1. Clamping the apron

[0054] Driving the opening and closing: The double-output shaft motor 201 in the rotating mechanism 200 is started, driving the worm 202 to rotate. The worm 202 meshes with the worm gear 203, driving the long shaft 204 to rotate. The long shaft 204 is connected to the swing arm 207 through the flange 206, causing the swing arm 207 to perform the opening and closing action.

[0055] Adaptive adjustment: The swing arm 207 is connected to the conveying mechanism 100 through a parallelogram connecting rod system composed of the left long connecting rod 211, the right long connecting rod 212 and the short connecting rod 213. The connecting rod system adjusts the opening degree and contact angle of the conveying mechanism 100 according to the size of the apron, ensuring that the conveyor belt 114 fits closely against the side of the apron.

[0056] Friction clamping: The conveyor belt 114 in the conveying mechanism 100 fits against the side of the apron, firmly clamping it using friction. The tension spring 112 and the support column 113 maintain the tension of the conveyor belt 114, ensuring stability during the clamping process.

[0057] 2. Moving the apron

[0058] Conveyor belt drive: After clamping is completed, the DC reduction motor (110) in the conveying mechanism 100 is started, driving the conveyor belt 114 to rotate through the belt pulley 111.

[0059] Transfer path: The conveyor belt 114 relies on friction to move the apron from the lifting mechanism (the vertical movement channel within the airport) to the parking area (the parking area within the airport, similar to a parking space), or from the parking area to the ground vehicle.

[0060] Smooth operation: The first conveyor idler 104, the second conveyor idler 105, the first guide shaft 106, and the second guide shaft 107 support the conveyor belt 114 to ensure the smoothness of the apron during movement.

[0061] 3. Docking with the ground vehicle

[0062] Height and angle adjustment: The rotating mechanism 200 adjusts the height and angle of the conveying mechanism 100 through the link system to precisely match the height of the ground vehicle (200 - 500 mm).

[0063] Transfer to the vehicle: The conveyor belt 114 moves the clamped apron together with the drone on it to the ground vehicle, realizing seamless docking between the drone and the logistics transport vehicle.

[0064] Release the apron: After docking is completed, the double-output shaft motor 201 rotates in the reverse direction to drive the conveying mechanism 100 to release the apron, completing the transfer.

[0065] As described above, the present invention can be preferably realized.

[0066] The embodiments of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
