Technical Field

[0001] This utility model relates to the field of drone charging technology, specifically to a universal charging station for drones. Background Technology

[0002] With the widespread application of drones in fields such as power grid inspection, oil and gas pipeline inspection, and environmental monitoring, the frequency of drone operations and the complexity of their tasks are constantly increasing, which places higher demands on the drones' endurance.

[0003] As fully automated operational hubs, drone airports can solve the challenges of takeoff and landing in complex terrains by providing standardized takeoff and landing platforms, enabling unattended continuous inspections. Drone airports can be categorized into fixed, vehicle-mounted, and portable types. Currently, to meet the endurance requirements of drones, drone airports commonly use battery replacement. However, traditional manual battery replacement is inefficient and requires human supervision. While automated battery replacement using mechanical equipment necessitates complex mechanical structures, has limited capacity, struggles to meet the charging needs of multiple drones, and is costly. Utility Model Content

[0004] To address one or more shortcomings of the existing technology, this utility model provides a universal charging airport for drones. By configuring charging piles, drones can be charged without removing the drone batteries, enabling unmanned operation. Furthermore, the airport has a simple structure, low cost, and can charge multiple drones simultaneously, effectively improving the drone airport's capacity.

[0005] To achieve the above objectives, this utility model adopts one or more of the following technical solutions:

[0006] A universal charging station for drones includes:

[0007] The airport cabin contains several charging piles, each with a charging interface for physical docking with the drone to establish a charging circuit. An airport entrance / exit is located on one side of the airport cabin and is equipped with an automatic access control system.

[0008] The apron is located on the outside of the airport cabin.

[0009] As a further implementation, the top of the airport cabin is equipped with a canopy to form a closed structure. The canopy is made of glass, which can reduce interference with RTK and BeiDou positioning signals.

[0010] As a further implementation, the automatic access control assembly includes a roller shutter door, a motor, a transmission chain, and a control element. The motor is electrically connected to the control element, and the motor drives the roller shutter door's roller shaft through the transmission chain.

[0011] As a further implementation, a meteorological monitoring pole is fixedly installed on the helipad, and a meteorological observation component is installed on the meteorological monitoring pole. The meteorological observation component is connected to the main control system. The meteorological observation component includes a wind speed and direction sensor, a temperature, humidity and air pressure sensor, a precipitation sensor and a visibility sensor, so that the main control system can accurately determine whether the conditions for UAV take-off and landing are met based on meteorological monitoring information and temperature information.

[0012] As a further implementation, the charging pile is provided with two charging interfaces, one positive and one negative, and a plurality of infrared emitting modules are arranged between the two charging interfaces. The plurality of infrared emitting modules are integrated and fixedly installed on the charging pile.

[0013] As a further implementation, a guide rail is fixedly connected to the side of the charging pile facing the drone body. The guide rail is laid on the ground and has a set length to guide the wheels of the drone that are close to the charging pile.

[0014] As a further implementation, the free end of the guide rail is provided with a guide groove, the width of which gradually increases from the near end to the far end of the charging pile.

[0028] Example 1

[0029] In one typical embodiment of this application, a universal charging station for unmanned aerial vehicles (UAVs) is provided, such as... Figures 1-3 As shown, it includes:

[0030] The airport cabin 1 has several charging piles 4 fixedly installed inside it. Each charging pile 4 is equipped with a charging interface 8 for physical docking with the drone to establish a charging circuit. An airport entrance / exit 7 is opened on one side of the airport cabin 1, and an automatic access control component 5 is installed at the airport entrance / exit 7.

[0031] The apron 2 is located on the outside of the airport cabin 1.

[0032] Specifically, such as Figure 1 As shown, the interior of the airport cabin 1 is a rectangular area, and the apron 2 is located adjacent to the airport cabin 1 on the outside, serving as a platform for drone take-off and landing. The apron 2 has circular area markings and I-shaped take-off and landing markings 14 painted or pasted on its surface. The I-shaped take-off and landing markings 14 are positioned at the center of the circular area markings to guide the drone to the optimal take-off and landing positions.

[0033] In this embodiment, a canopy 3 is fixedly installed on the top of the airport cabin 1, forming a closed structure to protect the drones and charging piles parked inside from damage caused by severe weather. In this embodiment, the canopy 3 is made of glass, which can reduce the interference of the canopy on RTK positioning signals and BeiDou navigation positioning signals, ensuring the navigation accuracy of the drones.

[0034] like Figure 1 and Figure 2 As shown, an airport entrance 7 is located on the side of the airport cabin closest to the apron. The airport entrance 7 faces the circular area marker on the apron 2. When a UAV lands within the circular area, it can travel in a straight line to enter the airport cabin 1 through the airport entrance 7 to charge or wait for a flight mission. An automatic access control component 5 is installed at the airport entrance 7, which can automatically open and close the door according to central control commands. The automatic access control component 5 adopts an existing structure, including a roller shutter door, a motor, a transmission chain, and a control element. The motor is electrically connected to the control element, and the control element establishes communication with the airport main control system (not shown in the figure). When an authorized UAV needs to enter or exit, such as when a UAV receives a mission command to leave or when a UAV needs to enter the station after completing an inspection, the control element receives the command and controls the motor to start, which drives the roller shutter door's shaft to rotate via the transmission chain, opening the roller shutter door. Under normal circumstances, the roller shutter door is closed to prevent rain, snow, or unauthorized personnel or objects from entering the airport cabin.

[0035] In addition, to ensure safety, infrared photoelectric sensors are installed on both sides of the roller shutter door frame. If a person or object passes by when the roller shutter door is closing, the roller shutter door will stop immediately and open in the opposite direction to prevent injury.

[0036] Specifically, such as Figure 1As shown, a meteorological monitoring pole 12 is fixedly installed on one corner of the helipad 2. The meteorological monitoring pole 12 is vertically installed, and a meteorological observation component 13 is installed at a certain height on the upper part of the meteorological monitoring pole 12. In this embodiment, the meteorological observation component 13 includes a wind speed and direction sensor, a temperature, humidity and air pressure sensor, a precipitation sensor and a visibility sensor. The meteorological observation component 13 is connected to the main control system and sends the monitoring data to the main control system in real time. The main control system determines whether the conditions are met for the UAV to go out and perform a mission based on all the meteorological information obtained, so as to ensure the safety of the UAV when it goes out to operate.

[0037] Specifically, in combination Figure 1 and Figure 2 As shown, several charging piles 4 are fixedly installed inside the airport cabin 1. The charging piles 4 are distributed along the sides of the airport cabin 1, with adjacent charging piles 4 on the same side spaced evenly apart. In this embodiment, the charging piles 4 are fixedly installed on the concrete floor inside the airport cabin 1 using mechanical anchor bolts. Combined with... Figure 3 As shown, the charging pile 4 has two charging ports 8 on one side. The charging ports 8 use a charging copper core, which can physically connect with the charging connector on the drone to form a charging circuit. A ring-shaped outer electromagnet is coaxially arranged around the charging copper core. The outer electromagnet is normally closed and can be magnetically fixed with the drone to improve the stability of the charging port connection. After charging is completed, the coil of the outer electromagnet is energized, and the outer electromagnet loses its magnetism.

[0038] To further improve the versatility of charging stations, such as Figure 2 and Figure 3 As shown, multiple positive and negative charging ports 8 are installed at both ends of the charging pile 4. In this embodiment, three charging ports 8 are provided on the left and three on the right, which can be adapted to the landing gear width of different drone models. Therefore, for a given charging pile, as long as the charging power and current of the drone battery are matched, the distance between the multiple ports on the charging pile in this embodiment can match the landing gear width of most drones currently on the market, making the charging pile more compatible and further improving the versatility of the airport where the charging pile is located.

[0039] In this embodiment, the charging pile is equipped with a local controller and an AC / DC converter. The local controller establishes communication with the main control system of the drone airport, reporting data such as the charging pile ID, charging status, power level, and error codes to the main control system to achieve real-time monitoring of the charging pile. The AC / DC converter is used to convert the AC input of the charging pile into DC output. The AC / DC converter is connected to the outer electromagnet through an electromagnet drive circuit. When a drone on a charging pile finishes charging, the main control system sends a command to the local controller. The local controller sends a low-level signal to trigger the electromagnet drive circuit, which then powers on the outer electromagnet to unlock it, allowing the drone to detach from the charging pile.

[0040] In this embodiment, combined with Figure 2 and Figure 3 As shown, a guide rail 10 is fixedly connected to the side of the charging pile 4 where the charging interface is located. The guide rail 10 is laid horizontally on the ground and fixed with rivets. The guide rail 10 has a set length and can guide the drone 1000 near the charging pile. When the walking wheels of the drone 1000 approach the charging pile 4 along the guide rail 10, magnetic fixation and precise docking of the charging interface can be achieved, thereby quickly realizing positioning and charging. A guide groove 11 is provided at the free end of the guide rail 10. The width of the guide groove 11 gradually increases from the near end to the far end of the charging pile.

[0041] In this embodiment, as Figure 3 As shown, the charging pile 4 is also equipped with several infrared transmitting modules 9. The infrared transmitting modules 9 are integrated between the two charging interfaces 8 and can cooperate with the drone for infrared navigation and positioning to guide the drone to the charging interface of the charging pile accurately.

[0042] In addition, such as Figure 1 As shown, the airport cabin 1 is equipped with a temperature and humidity control module 6. The temperature and humidity control module 6 adopts a constant temperature and humidity precision air conditioning system, which is fixedly installed on the side wall of the airport cabin 1. It can accurately maintain a constant temperature and humidity environment inside the airport, effectively protect the drone and other electronic equipment, and thus extend the service life of the drone.

[0043] The drone airport of this invention has a simple structure, does not require the installation of large mechanical equipment, and can be easily built at high places by means of bottom beams, building houses, etc. It can effectively prevent theft and damage, and has low construction difficulty.

[0044] The process of drones entering and exiting the drone airport in this embodiment is as follows:

[0045] When a drone needs to leave the station and take off: After the remote control center issues a takeoff inspection command to the drone airport, the airport's main control system first determines whether the takeoff conditions are met based on the external meteorological information and temperature conditions sent by the meteorological observation component 13. After confirming that takeoff is possible, the main control system automatically detects the status of each drone 1000 in the airport cabin, including battery power, equipment health, etc., and selects available drones that meet the mission requirements. After receiving the command, the target drone executes a self-check procedure. After confirming that the status is normal, it starts the self-drive system to drive out of the airport entrance 7, arrives at the I-shaped takeoff and landing mark 14 on the apron, and then takes off.

[0046] When the returning drone comes to the charging station: After landing on the apron 2, the drone 1000 automatically retracts its propellers and activates its self-drive module, moving to the airport entrance / exit 7. The automatic access control component 5 senses the drone's identity and opens the roller shutter door. The drone 1000 enters the airport cabin 1 along the navigation path and is guided by infrared to the target charging pile 4 assigned by the main control system. It then travels through the guide trough 11 and guide rail 10 to reach the charging interface 8 of the target charging pile for charging.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that this utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
