Specific embodiments

[0023] The following describes in detail the preferred embodiments of the present invention with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making the protection scope of the present invention more clearly defined.

[0024] Please refer to Figure 1-8 , the drone body includes an airframe 1 and a drone battery 2. A battery compartment 3 is provided below the airframe 1. Clamping grooves A4 are opened on both sides of the battery compartment 3. Battery buckles 5 are installed on both sides of the drone battery 2. The top of the battery buckle 5 is clamped in the clamping groove A4 to fix the drone battery 2 to the battery compartment 3; the drone battery 2 adopts a longitudinal insertion mechanism, which facilitates the quick replacement of the battery when the drone is paired with a battery replacement airport.

[0025] The battery replacement airport body includes a battery replacement box 6 and an airport cover 7. Connecting arms 8 are rotatably connected to both sides of the battery replacement box 6. The other ends of the connecting arms 8 are fixedly connected to the airport cover 7. A servo motor A9 is installed inside the battery replacement box 6. The output shaft of the servo motor A9 is fixedly connected to the connecting arm 8. The top of the battery replacement box 6 is set as a drone landing platform, and a battery replacement mechanism is installed inside the battery replacement box 6; when the drone replaces the battery, it lands on the drone landing platform at the top of the battery replacement box 6. The servo motor A9 controls the connecting arm 8, and the airport cover 7 can be opened from above the battery replacement box 6 when the drone needs to replace the battery and closed from above the battery replacement box 6 when there is no drone replacing the battery, which can avoid dust pollution of the drone landing platform on the battery replacement box 6.

[0026] The drone landing platform is provided with a battery swapping port. Inside the battery swapping box 6, a rod holder 10 is fixedly installed. An expansion rod 11 is hinged on the rod holder 10. The other end of the expansion rod 11 is hinged with a battery swapping door panel 12. The rear side of the battery swapping door panel 12 is hinged to the drone landing platform, and the battery swapping door panel 12 corresponds to the battery swapping port. The contraction of the expansion rod 11 can control the opening of the battery swapping door panel 12, facilitating the passage of the drone battery 2 during the battery swapping operation. When there is no battery swapping operation, the extension of the expansion rod 11 will automatically push and close the battery swapping door panel 12.

[0027] The battery swapping mechanism includes a servo motor B13. The servo motor B13 is installed on the inner bottom of the battery swapping box 6. A threaded rod A14 is fixedly installed on the output shaft of the servo motor B13. A slider A15 is threadedly connected to the threaded rod A14. The slider A15 is slidably connected to the inner bottom of the battery swapping box 6. A movable frame 16 is fixedly connected to the slider A15. A servo motor C17 is fixedly installed on the movable frame 16. A threaded rod B18 is fixedly installed on the output shaft of the servo motor C17. A slider B19 is threadedly connected to the threaded rod B18. The slider B19 is slidably connected to the movable frame 16. A sliding frame 20 is fixedly installed on the slider B19. A servo motor D21 is fixedly installed on the sliding frame 20. A threaded rod C22 is fixedly installed on the output shaft of the servo motor D21. A slider C23 is threadedly connected to the threaded rod C22. The slider C23 is slidably connected to the sliding frame 20. A clamping and placing component is installed on the slider C23. By driving the threaded rod A14 to rotate through the servo motor B13, the slider A15 is driven to move. The servo motor C17 drives the threaded rod B18 to rotate, thereby driving the slider B19 to move. The servo motor D21 drives the threaded rod C22 to rotate, thereby driving the slider C23 to move, enabling the clamping and placing component to move in the three axes of up and down, left and right, and front and back, facilitating the battery swapping operation.

[0028] The clamping and placing component includes a servo motor E24. A double-threaded rotating rod 25 is fixedly connected to the output shaft of the servo motor E24. Both ends of the double-threaded rotating rod 25 are threadedly connected with sliders D26. The sliders D26 are slidably connected to the slider C23. Clamping pieces 27 are fixedly installed on the sliders D26. When the servo motor E24 drives the double-threaded rotating rod 25 to rotate, the sliders D26 will move closer to or away from each other simultaneously, and thus can drive the clamping pieces 27 to clamp or release the battery buckle 5, achieving the disassembly and installation of the drone battery 2.

[0029] Adopting a vertical three-axis battery swapping mechanism, after the drone lands on the drone landing platform, the battery swapping door panel 12 will open. The battery swapping mechanism drives the clamping and placing component to take out the drone battery 2 from below the drone and reinsert a fully charged battery. There is no complex mechanical movement during the battery swapping process, and the whole process is fast and stable.

[0030] The upper top of the battery swapping box 6 is fixedly installed with a battery charging bin 28, and clamping grooves B29 are formed on both sides of the battery charging bin 28; when the UAV battery 2 is removed from the battery bin 3 and sent to and inserted into the battery charging bin 28 through the cooperative operation of the battery swapping mechanism, the clamping piece 27 releases the battery buckle 5, and the UAV battery 2 will be fixed on the battery charging bin 28 for automatic charging.

[0031] A number of groups of battery charging bins 28 are provided; this facilitates battery swapping for more groups of UAVs.

[0032] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
