[0002] At present, unmanned aircraft, referred to as "drones", are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices, or are operated completely or intermittently autonomously by onboard computers.

[0003] Among them, short battery life is an important reason restricting the development of the multi-rotor UAV industry. Multi-rotor UAVs need to provide lift to offset their own weight. Generally, the battery life is less than 30 minutes. The UAV itself has a low battery life. In order to ensure that the UAV operation can be completed, the UAV needs to be charged frequently.

[0004] The conventional way to charge drones in the market is to charge them through external connection devices. This method not only requires a power supply and a charging cable, but also requires cumbersome operating steps. For drones operating outdoors, this method of operation is difficult to meet the charging needs of drones. Therefore, it is necessary to design a new technical solution to solve the problem. The drone can be automatically and efficiently charged through a mobile power box. Summary of the invention

The present invention has multiple groups of equidistantly distributed rotating grooves on the bottom of the two groups of brackets, and a rotating ball is rotatably installed in each group of rotating grooves. When the drone lands on the weighing pressure plate inside the charging box, the brackets on both sides of the bottom of the drone will preferentially contact the weighing pressure plate. At the same time, multiple groups of equidistantly distributed rotating balls are rotatably installed on the bottom of the two groups of brackets to ensure that when the drone is pushed by the clamping and pushing mechanism, the friction between the two groups of brackets at the bottom of the drone and the weighing pressure plate can be greatly reduced, which facilitates the adjustment of the drone in any direction on the top of the weighing pressure plate.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] Example 1: See Figure 1-5A drone charging device includes a charging box 1, a battery pack is fixedly installed at the bottom of the inner cavity of the charging box 1, a protective plate 11 is fixedly installed on the top of the battery pack, a weight-measuring pressure plate 12 is installed on the top of the protective plate 11, a pressure sensor is installed in the weight-measuring pressure plate 12, a drone 13 is placed on the top of the charging box 1, and a docking mechanism is installed on the charging box 1 and the drone 13, through which the charging end of the drone 13 can be connected to the power end of the charging box 1, and the drone 13 can be charged efficiently. The docking mechanism includes fixed on both sides of the top of the drone 13 A fixed bracket 2, a horizontal plate 21 fixedly installed on both sides of the two groups of brackets 2, a charging head 22 fixedly installed at one end of the horizontal plate 21 on one side, a docking port 23 fixedly installed on one side of the inner wall of the charging box 1, and a controller 24 connected to the docking port 23, the docking port 23 and the controller 24 are connected to the battery pack through wires, the docking port 23 and the charging head 22 correspond to each other, the two sides of the two groups of horizontal plates 21 are fixedly installed on the side walls of the two groups of brackets 2 respectively, and the two groups of brackets 2 are concave brackets 2, and the charging head 22 is connected to the drone 13 through wires;

[0030] A first limiting slot 3 is horizontally opened on one side of the inner cavity of the charging box 1, and a second limiting slot 34 is longitudinally opened on the other side of the inner cavity of the charging box 1. A clamping and pushing mechanism is installed in the first limiting slot 3 and the second limiting slot 34. The clamping and pushing mechanism can preferentially clamp the drone 13 that falls on the weighing pressure plate 12, and then slowly push the drone 13 to one side to ensure that the charging end on the drone 13 is connected to the power terminal of the charging box 1, and automatically charge the drone 13. The clamping and pushing mechanism includes a double-ended device rotatably installed in the first limiting slot 3. The bidirectional screw rod 31, the first limit slider 32 threadedly installed on both sides of the bidirectional screw rod 31, the clamping rod 33 fixedly installed on the side walls of the two groups of first limit sliders 32, the screw rod 35 rotatably installed in the second limit slide groove 34, the second limit slider 36 threadedly installed on one end of the screw rod 35, and the push rod 37 fixedly installed on the side wall of the second limit slider 36, the second limit slider 36 is slidably connected to the second limit slide groove 34, the two groups of first limit sliders 32 are slidably connected to the first limit slide groove 3, and a push plate is fixedly installed in the middle of the push rod 37.

[0031] When in use, first combine with the clamping and pushing mechanism through the docking mechanism. When the drone 13 keeps approaching the charging box 1, the first motor 52 on the side wall of the support seat 14 can be driven to drive the cover 15 inside the support seat 14 to rotate, and the weighing pressure plate 12 inside the charging box 1 is continuously presented. When waiting for the drone 13 to fall to the top of the weighing pressure plate 12 inside the charging box 1, the pressure sensor installed in the weighing pressure plate 12 can transmit the signal to the control processor, and preferentially drive the second motor 53 to drive the bidirectional screw rod 31 to rotate. The first limit slider 32 threadedly installed with the two sets of bidirectional screw rod 31 will move synchronously inward along the direction of the first limit slide groove 3, ensuring that the two sets of clamping rods 33 can firmly clamp the two sides of the drone 13 on the top of the weighing pressure plate 12. At the same time, the third motor 54 is driven to drive the screw 35 in the clamping and pushing mechanism to rotate. The first limit slider 32 threadedly installed with the screw 35 will move along the direction of the first limit slide groove 3. The drone 13 is moved in the direction of the docking port 23, and the docking mechanism is installed on the charging box 1 and the drone 13, so that the charging head 22 on the drone 13 can be docked with the docking port 23 on the charging box 1, ensuring that the device can automatically charge the drone 13 with low power without human operation. At the same time, multiple groups of equidistantly distributed rotating grooves 5 are provided at the bottom of the two groups of brackets 2, and a rotating ball 51 is rotatably installed in each group of rotating grooves 5. When the drone 13 lands on the weighing pressure plate 12 inside the charging box 1, the brackets 2 on both sides of the bottom of the drone 13 will preferentially contact the weighing pressure plate 12. At the same time, multiple groups of equidistantly distributed rotating balls 51 are rotatably installed at the bottom of the two groups of brackets 2, ensuring that when the drone 13 is pushed by the clamping pushing mechanism, the friction between the two groups of brackets 2 at the bottom of the drone 13 and the weighing pressure plate 12 can be greatly reduced, so that the drone 13 can be easily adjusted in any direction on the top of the weighing pressure plate 12.

[0032] For details, see Figure 1-5 A first limiting groove 4 is provided on one side of the inner cavity of the charging box 1, and the first limiting groove 4 corresponds to the first limiting slide groove 3. A first limiting rod 41 is fixedly installed in the first limiting groove 4, and first limiting blocks 42 are slidably installed at both ends of the first limiting rod 41. The two groups of first limiting blocks 42 are slidably connected to the first limiting groove 4, and the side walls of the two groups of first limiting blocks 42 are respectively fixedly installed with the other ends of the two groups of clamping rods 33. A second motor 53 is fixedly installed at one end of the side wall of the charging box 1, and the second motor 53 drives the output The first end is connected to the transmission shaft for transmission, and the other end of the transmission shaft is fixedly installed with one end of the bidirectional screw rod 31, and the third motor 54 is driven to drive the screw rod 35 in the clamping and pushing mechanism to rotate, and cooperate with the second limit groove 43, the second limit rod 44 and the second limit block 45 to limit the first limit slider 32 and the push rod 37, so as to ensure that the first limit slider 32 threadedly installed with the screw rod 35 will move along the direction of the first limit groove 3, and the clamped drone 13 will continue to approach the docking interface 23.

[0033] For further information, see Figure 1-5 A second limiting groove 43 is provided on the other side of the inner cavity of the charging box 1. The second limiting groove 43 corresponds to the second limiting slide groove 34. A second limiting rod 44 is fixedly installed in the second limiting groove 43. A second limiting block 45 is slidably installed on the second limiting rod 44. The second limiting block 45 is slidably connected to the second limiting groove 43. The side wall of the second limiting block 45 is fixedly installed with the other end of the push rod 37. A third motor 54 is fixedly installed at the other end of the side wall of the charging box 1. The output end of the third motor 54 drives the transmission The two-way screw 31 is connected by shaft transmission, and the other end of the transmission shaft is fixedly installed with one end of the screw 35. By driving the second motor 53 to drive the bidirectional screw 31 to rotate, and in conjunction with the first limit groove 4, the first limit rod 41 and the first limit block 42, the two sets of clamping rods 33 can be limited. The first limit slider 32 installed with two sets of threads on the bidirectional screw 31 will move inward synchronously along the direction of the first limit slide groove 3, ensuring that the two sets of clamping rods 33 can firmly clamp the two sides of the drone 13 on the top of the weighing pressure plate 12.

[0034] Further, see Figure 1-5 A support base 14 is fixedly installed on one side of the top of the charging box 1, and a cover 15 is rotatably installed inside the support base 14 through a rotating shaft. A rubber pad 16 is fixedly installed on the inner wall of the cover 15, and the cover 15 corresponds to the upper port of the charging box 1. A first motor 52 is fixedly installed on one side of the support base 14, and the driving output end of the first motor 52 is connected to the transmission shaft, and the other end of the transmission shaft is fixedly installed with a rotating shaft on one side. By driving the first motor 52 on the side wall of the support base 14, the cover 15 inside the support base 14 is driven to rotate, and the weighing pressure plate 12 inside the charging box 1 is continuously presented, so that the drone 13 can fall to the top of the weighing pressure plate 12 inside the charging box 1. After the charging box 1 charges the drone 13, the first motor 52 can be driven again to close the cover 15 to protect the drone 13.

[0035] It is worth noting that see Figure 1-5 , the bottom of the two groups of brackets 2 are provided with multiple groups of equidistantly distributed rotating grooves 5, and a rotating ball 51 is rotatably installed in each group of rotating grooves 5. When the drone 13 lands on the weighing pressure plate 12 inside the charging box 1, the brackets 2 on both sides of the bottom of the drone 13 will preferentially contact the weighing pressure plate 12. At the same time, the bottom of the two groups of brackets 2 are rotatably installed with multiple groups of equidistantly distributed rotating balls 51, ensuring that when the drone 13 is pushed by the clamping and pushing mechanism, the friction between the two groups of brackets 2 at the bottom of the drone 13 and the weighing pressure plate 12 can be greatly reduced, so that the drone 13 is convenient to adjust in any direction on the top of the weighing pressure plate 12.
