Description

Technical Field

[0001] The present invention belongs to the technical field of unmanned aerial vehicles (UAVs), and in particular relates to a flip-type UAV airport shared by multiple aircraft. Background Art

[0002] With growing awareness of the value of drone applications, drones are experiencing rapid growth in the consumer, industrial, and military markets. Drones are finding increasing application in numerous fields. The widespread use of drones and the increasing automation of drone operations have led to the emergence of drone airports. To achieve automated management, each drone must be equipped with a storage bay, allowing for automatic parking and takeoff.

[0003] Most drones are fixed-wing, vertical takeoff and landing (VTOL) drones. This limits the hatch opening and closing method, requiring doors to be located on the top surface. Some fixed-wing drones are larger, requiring more space to open the hatch and requiring a higher level of power. In drone airport design, doors for multi-rotor drone airports often utilize left-right sliding doors. Lifting platforms typically utilize an up-and-down motion, which underutilizes the entire airport space, creates a complex structure, and leads to high costs and a high failure rate. The top door is independently driven and opens and closes independently, requiring a complex waterproofing design to ensure waterproof performance. Summary of the Invention

Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0033] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0034] like Figures 1 to 5 As shown, the present invention provides a flip-type multi-machine shared drone airport, including a main frame 10, a flip platform assembly 20 is provided on the side of the main frame 10, and the flip platform assembly 20 includes a first driving mechanism 21, a rotating arm 23, a rotating axis fixing block 22 and a side door assembly 24, the rotating axis fixing block 22 is provided with a through hole, the motor shaft of the first driving mechanism 21 is connected to the front end of the rotating arm 23 through the through hole, the rotating arm 23 is connected to the side door assembly 24, the first driving mechanism 21 drives the rotating arm 23 to rotate through the motor shaft, thereby driving the side door assembly 24 to rotate, and the rotating axis fixing block 22 is fixed on the main frame 10.

[0035] Specifically, such as Figures 1 to 4As shown, the flip-type multi-drone shared drone airport comprises a main frame 10 and a flip platform assembly 20. The flip platform assembly 20 is connected to one side of the main frame via a rotating shaft fixing block 22. The motor shaft of the first drive mechanism 21 passes through a through-hole in the rotating shaft fixing block 22 and connects to the front end of a rotating arm 23. When the first drive mechanism 21 rotates the motor shaft clockwise, it causes the rotating arm 23 to flip upward above the main frame, allowing a drone 30 to land on the side door assembly 24. After the side door assembly 24 secures the drone, the first drive mechanism 21 drives the motor shaft counterclockwise, causing the rotating arm 23 to rotate downward, thereby moving the side door assembly downward. Once in position, the drone battery can be automatically replaced or stored. The drone airport utilizes a flip platform assembly mounted on the side of the main frame. Drones land on the side door assembly within the flip platform assembly and are then driven by the first drive mechanism to rotate 270 degrees up and down. The drive mechanism occupies a small space, resulting in high space utilization. The logic control is simple, and when storing the drone, the side door assembly can serve as the airport's side door, saving costs. Preferably, the first drive mechanism 21, the rotating arm 23, and the rotating shaft fixing block 22 are respectively two in number and are matched to be arranged on both sides of the side door assembly 24, so that the driving force is more balanced and the movement is smoother during flipping. The end faces of the rotating shaft fixing block and the rotating arm can be arc-shaped, which makes the movement smoother. A groove can also be provided in the rotating arm 23, and a rotating shaft movable plate is fixed in the groove. The motor shaft of the first drive mechanism drives the rotating arm 23 to flip up and down through the rotating shaft fixing block 22 and the rotating shaft movable plate. The rotating shaft movable plate makes the rotating arm move more smoothly, reduces the power of the driving mechanism, and saves energy. Preferably, the flip platform assembly 20 also includes a rotation sensor, which is placed on the rotating arm to measure the angle of rotation of the rotating arm and the distance of movement, thereby improving the accuracy of the rotating arm rotation and the working efficiency of the drone airport.

[0036] Further, such as Figure 2 As shown, the side door assembly 24 includes a second driving mechanism 241, a bidirectional screw rod 242, two slider connectors 243, two push rod connectors 244, two push rods 245 and a supporting plate 246. The second driving mechanism 241 drives the bidirectional screw rod 242 to rotate, and the two slider connectors 243 are symmetrically sleeved on the bidirectional screw rod 242. The two push rod connectors 244 are respectively connected to the slider connector 243. The upper ends of the two push rod connectors 244 are respectively connected to the two push rods 245. The two push rods are driven by the second driving mechanism 241 to move back and forth left and right on the supporting plate 246.

[0037] Specifically, the second drive mechanism 241 drives the bidirectional screw 242, which has a right-handed thread and a left-handed thread. Two slider connectors 243 are respectively mounted on the right-handed and left-handed threads. When the bidirectional screw rotates, the two slider connectors rapidly move toward or away from each other. The bidirectional screw arranges the wires evenly and precisely according to the set spacing. The reciprocating direction is reliable, and there are no malfunctioning or switching issues. The wire arrangement thrust is high, without causing wire compression or unreeling. The structure is simple and easy to manufacture. The two slider connectors are respectively connected to two push rod connectors 244, the upper ends of which are respectively connected to two push rods 245. When the second drive mechanism 241 drives the bidirectional screw 242 in the forward direction, the right-handed thread drives one slider connector to the right, while the left-handed thread drives the other slider connector to the left. This in turn drives the two push rods to move to the sides, releasing the drone that has landed on the support plate, allowing it to take off. When the second drive mechanism 241 drives the bidirectional screw rod 242 to rotate in the opposite direction, the right-handed thread drives the slider connector to the left, while the left-handed thread drives the slider connector to the right. This in turn drives the two push rods toward the center, clamping the drone that has landed on the support plate. The first drive mechanism then drives the flip platform assembly, and the side door assembly flips with the drone. Once flipped into place, the battery can be replaced or the drone can be stored at the drone airport. The second drive mechanism uses a single-motor bidirectional screw mechanism to drive the push rods to clamp or release the drone, resulting in a simple structure that saves space and cost. The second drive mechanism motor is preferably a stepper motor or servo motor, which simplifies the logic control. After flipping, the support plate can be used as a side door. Preferably, the side door assembly also includes a side door frame, and the support plate is mounted within the side door frame. Alternatively, a side door can be installed within the side door frame, and the second drive mechanism, the two push rod connectors, and the support plate are placed above the side door. This structure can achieve excellent waterproofing.

[0038] Further, such as Figure 3 As shown, two flip platform assemblies 20 are installed on the left and right sides of the main frame to accommodate two drones. Two flip platform assemblies are installed on opposite sides of the main frame 10 to accommodate two drones, effectively utilizing the space. When the drone airport is located outdoors, the two drones can take turns performing missions or take off in sequence. This breaks the current limitation of requiring one drone airport for each drone, significantly saving costs.

[0039] Further, such as Figure 1 、 Figure 2As shown, the push rod is W-shaped. When the drone 30 lands on the supporting plate 246, the two push rods 245 move toward the center to clamp the drone tripod 31. The push rod W-shaped vertex limit clamps the drone tripod 31. The push rod adopts a W-shape. When the drone lands on the supporting plate 246, if it does not land at the center position and there is a deviation, the push rod W-shaped bevel will guide and push the drone to move toward the center until the drone's tripod moves to the push rod W-shaped vertex. The four vertex limits of the two push rod W-shaped vertex clamp the drone tripod 31, thereby fixing and clamping the drone, making it convenient for the drone to automatically change batteries without displacement error. Preferably, a drone foot buckle 32 is also provided at the bottom of the drone tripod to further stabilize the drone, so that the drone is firmly clamped to the side door assembly, and will not move when the side door assembly flips, thereby making the clamping more secure.

[0040] Further, such as Figure 4 、 Figure 5 As shown, the main frame is topped with a top cover 15 and a front cover 16. The top cover 15 covers the rotating shaft fixing block 22 at both ends and is then connected to the side surfaces of the main frame. The front cover 16 is fixed to the bracket to form a closed cavity. By covering the rotating shaft fixing block and extending to the side surfaces of the main frame, the top cover is a single cover plate, eliminating the need for waterproofing, achieving a good waterproofing effect and maintaining a simple structure.

[0041] Further, such as Figure 1 、 Figure 4 As shown, a bracket 14 is provided on the bottom surface of the main frame 10, and a drone battery charging slot 18 is further provided inside the airport, and the charging slot 18 is fixed to the bracket 14. A battery charging slot is provided on the bracket 14, and a drone battery 33 is placed in the charging slot for charging. The charging slot can charge multiple drone batteries 33 as needed, saving space.

[0042] Further, such as Figure 1 、 Figure 4 As shown, the main frame is provided with an X-axis track assembly 11, a Y-axis track assembly 12, and a Z-axis track assembly 13. An automatic battery-changing mechanical gripper device 17 moves on the X-axis track assembly 11, the Y-axis track assembly 12, and the Z-axis track assembly 13 to automatically change the battery of the drone. The automatic battery-changing mechanical gripper device 17 uses a driving device to move the X-axis track assembly 11, the Y-axis track assembly 12, and the Z-axis track assembly 13 accordingly to grip the battery on the drone and place it in the charging slot for charging. The fully charged battery is then gripped and installed on the drone, thus completing the automatic battery replacement process.

[0043] Further, such as Figure 1 、 Figure 4As shown, the airport also includes an electrical control cabinet 40, which is connected to the main frame 10. Control electrical components (not shown) are placed in the electrical control cabinet. The control electrical components, such as the motor controller, control the motor of the drive mechanism to operate according to the set direction, speed, angle, and response time through the motor controller. Placing the control electrical components in the electrical control cabinet facilitates wiring and management.

[0044] The present invention incorporates a flip platform assembly on the side of the main frame. A drive mechanism drives the flip platform assembly to flip. The side door assembly and flip platform are integrated into one design, moving simultaneously and reducing drive components. The drive mechanism occupies little space, resulting in high space utilization, a simple structure, low cost, and a low failure rate. The device rotates 270 degrees up and down, driven by the drive mechanism. The drive mechanism occupies little space, resulting in high space utilization. The logic control is simple, and the side door assembly can serve as the side door of a drone airport when storing drones, saving costs. The side door assembly carries the drone and flips it into position. Once fully flipped, the drone can be replaced with a battery or stored within the drone airport. This structure provides excellent waterproofing. Two flip platform assemblies are provided on opposite sides of the main frame to accommodate two drones, effectively utilizing the available space. When the drone airport is located outdoors, the two drones can take turns performing missions or take off in a sequential order. This overcomes the existing limitation of requiring one drone airport for each drone, significantly saving costs.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
