[0002] With the rapid development of my country's economy and society, drones have begun to be used in the civilian sector, and the adoption of cargo drones in the logistics industry has become a trend. Currently, many companies are preparing to develop drones for autonomous parcel delivery. Drones have solved many problems in the world today, and their development and use are a current trend in social development. Existing tonnage-class cargo drones are basically powered by battery packs, which are located in the bottom hatch of the cargo drone and can be removed for battery pack replacement.

[0003] However, in the current use of cargo drones, the replacement of the bottom drone battery pack is done manually. The process involves removing the hatch, removing the old battery, and then replacing it with a new one. The whole process is quite complicated and the replacement efficiency is low.

[0004] Based on this, this solution proposes a drone battery replacement mechanism. Utility Model Content

Crossbars 15 are slidably installed on both sides of the base 1, and a first motor 2 is fixedly installed at the front end of the base 1. A linkage rack 16 and a clamping frame 4 are respectively fixedly installed at both ends of the two crossbars 15. A central gear 17 located between the two linkage racks 16 is fixedly sleeved on the output shaft of the first motor 2. An indicator light 3 is fixedly installed on the top of the landing platform 13. With the above structural setup, the device is first pushed to a suitable position, and the drone stops on the landing platform 13 according to the indication. Starting the first motor 2 drives the rotation of the central gear 17, which in turn drives the two linkage racks 16 to move in opposite directions, thereby driving the two clamping frames 4 to move in opposite directions, thus clamping and fixing the drone and preventing the drone from falling due to accident, which would affect the battery replacement efficiency.

[0029] Combination Figure 1-4As shown, a mounting groove 22 is provided on the top of the fixing plate 11, and a third motor 24 is fixedly installed on one side of the fixing plate 11. A first lead screw 23 located in the mounting groove 22 is fixedly sleeved on the output shaft of the third motor 24. A first electric telescopic rod 5 is threaded onto the first lead screw 23. A first slide rail is fixedly installed in the mounting groove 22. A first slider is slidably installed on the first slide rail. The first slider is fixedly connected to the first electric telescopic rod 5. A crossbar 21 is fixedly installed on the output shaft of the first electric telescopic rod 5. A fourth motor 20 is fixedly installed on the crossbar 21. A second lead screw 19 is fixedly sleeved on the output shaft of the fourth motor 20. A second motor 14 is threaded onto the second lead screw 19. A second slide rail is fixedly installed on the crossbar 21. A second slider is slidably mounted on the rail, and the second slider is fixedly connected to the second motor 14. A movable frame 18 is fixedly sleeved on the output shaft of the second motor 14. An electric screwdriver 25 and a second electric telescopic rod 30 are fixedly mounted on the movable frame 18. A positioning frame 28 is fixedly mounted on the output shaft of the second electric telescopic rod 30. A positioning motor 29 is fixedly mounted on the positioning frame 28. A bidirectional lead screw 27 is fixedly sleeved on the output shaft of the positioning motor 29. Two clamping rods 26 are threaded onto the bidirectional lead screw 27. A third slide rail is fixedly mounted on the positioning frame 28. Two third sliders are slidably mounted on the third slide rail. The two third sliders are fixedly connected to the corresponding clamping rods 26. A charging box 7 is fixedly mounted on one side of the fixed plate 11. The system has multiple charging compartments 8, each containing a battery 6. With this structure, activating the third motor 24 rotates the first lead screw 23, which in turn moves the first electric telescopic rod 5 forward. This, in turn, moves the movable frame 18 and the electric screwdriver 25 forward. The electric screwdriver 25 can then be used to unscrew the screws used to install the drone's battery. Activating the second electric telescopic rod 30 moves the two clamping rods 26 forward. Activating the positioning motor 29 rotates the bidirectional lead screw 27, causing the two clamping rods 26 to move in opposite directions, thus clamping the battery. Finally, reversing the operation of the output shaft of the second electric telescopic rod 30 allows the drone to be launched. The battery is removed, and then the output shaft of the second motor 14 is activated, causing the movable frame 18 to rotate, so that the drone's battery faces the charging box 7. Then, the fourth motor 20 is activated, causing the second lead screw 19 to rotate, pushing the drone's battery towards the charging box 7. By activating the third motor 24 and the first electric telescopic rod 5, the drone's battery is adjusted to be inserted into the corresponding charging compartment 8 for charging. Then, the output shaft of the positioning motor 29 is activated in reverse, so that the drone's battery is no longer clamped. Then, the corresponding battery 6 is clamped and removed through the battery clamping structure. Then, the above series of operations are repeated in reverse to push the battery 6 to the drone's battery installation location for battery replacement.

With the above structure, the push handle 12 and four movable wheels 10 make it easy to move the entire device, increasing portability.

[0031] The working principle of this utility model is as follows: First, the device is pushed to a suitable position, and the drone docks on the docking platform 13 according to the instructions. Starting the first motor 2 drives the rotation of the central gear 17, which in turn drives the two linked racks 16 to move in opposite directions, thereby moving the two clamping frames 4 in opposite directions to clamp and fix the drone, preventing it from falling due to accidents and affecting battery swapping efficiency. Then, starting the third motor 24 drives the rotation of the first lead screw 23, which in turn drives the forward movement of the first electric telescopic rod 5, thereby moving the movable frame 18 and the electric screwdriver 25 forward. The screwdriver 25 can be used to unscrew the screws for installing the drone's battery. Then, starting the second electric telescopic rod 30 drives the two clamping rods 26 to move forward. Starting the positioning motor 29 drives the rotation of the bidirectional lead screw 27, thereby moving the two clamping rods 26 forward. The opposing movement of the clamping rods 26 clamps the battery. Then, by reversing the operation of the output shaft of the second electric telescopic rod 30, the drone's battery can be removed. Next, by activating the output shaft of the second motor 14, the movable frame 18 rotates, aligning the drone's battery with the charging box 7. Then, by activating the fourth motor 20, the second lead screw 19 rotates, pushing the drone's battery towards the charging box 7. By activating the third motor 24 and the first electric telescopic rod 5, the drone's battery is adjusted to be inserted into the corresponding charging compartment 8 for charging. Then, by reversing the operation of the output shaft of the positioning motor 29, the battery is no longer clamped, and the corresponding battery 6 is clamped and removed using the battery clamping structure. Repeating the above series of operations in reverse pushes the battery 6 to the drone's battery installation location for battery replacement. This utility model has a simple structure and is easy to use. The drone battery replacement mechanism, through its automatically positioned drone battery replacement structure, can automatically replace and recharge batteries, saving time and effort and achieving high replacement efficiency.
