Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and specifically relates to a charging device for an unmanned aerial vehicle. Background Art

[0002] An unmanned aerial vehicle, abbreviated as UAV, is an unpiloted aircraft mainly controlled by radio remote control or its own program. Its light and flexible characteristics make it a mechanical device for various military and civilian uses. However, the endurance of UAVs is limited and they need to be charged regularly.

[0003] Most of the UAVs are charged by wireless charging. Generally, the existing wireless charging products on the market usually consist of two main parts: a charger and a charging device. The charger usually consists of a power supply, a charging circuit and a wireless transmitter, and is used to convert electrical energy into a wireless signal and transmit it to the charging device. The charging device usually consists of a wireless receiver, a charging circuit and a battery, and is used to receive the wireless signal and convert it into electrical energy to charge the battery. The working principle of these wireless charging products is based on the principle of electromagnetic induction. When an alternating current passes through a coil, it will generate a magnetic field. If another coil is placed in this magnetic field, it will sense the change of the electromagnetic field and generate an electric current. This electromagnetic induction phenomenon is used in wireless charging. The coil in the charger generates a magnetic field, and the coil in the charging device receives this magnetic field and converts it into electrical energy to charge the battery.

[0004] Generally, after the UAV lands stably on the landing pad, the positioning mechanism is used to make the UAV automatically reach the designated position. When reaching the designated position, the wireless receiver on the UAV will dock with the signal of the wireless transmitter on the landing pad, so as to realize wireless charging.

[0005] However, in many cases, when the UAV is landing, there is no shelter above the UAV landing pad, that is, the top of the power supply device is exposed. After long-term use, part of the dust and bird droppings will accumulate on the top of the charging device for the unmanned aerial vehicle, affecting the use of the charging device for the unmanned aerial vehicle. For this reason, we propose a charging device for an unmanned aerial vehicle. Summary of the Utility Model

When the landing pad moves downward, it cooperates with the driving component to drive two groups of protective shells to close, thereby closing the top of the charging device, avoiding or reducing the accumulation of some dust and bird droppings on the top of the landing pad, effectively improving the practicability of the charging device for unmanned aerial vehicles, and solving the problems in the background.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0026] Please refer to Figures 1-6 , the present utility model provides a technical solution: a charging device for an unmanned aerial vehicle, including a support platform 2, a bottom shell 1 fixedly connected to the support platform 2, two groups of symmetrically distributed protective shells 3 rotatably installed on the support platform 2, an electric push rod 11 fixedly installed in the middle of the bottom shell 1, a cross-shaped body 15 fixedly connected to the output end of the electric push rod 11, a helipad platform 4 fixedly connected to the top of the cross-shaped body 15, a wireless charger 9 installed at the middle of the bottom of the helipad platform 4, a positioning component for positioning the unmanned aerial vehicle installed on the helipad platform 4, and a drive component for driving the rotation of the protective shell 3 installed on the bottom shell 1.

[0027] When the drone stably lands on the landing pad 4, the electric push rod 11 drives the landing pad 4 and the drone to move downward together. When the landing pad 4 moves downward, the positioning component simultaneously positions the drone for positioning, so that the drone and the wireless charger 9 at the bottom of the landing pad 4 are in close positions, ensuring stable signal transmission and avoiding unstable signals caused by the relatively far position between the drone and the wireless charger 9. Among them, when the landing pad 4 moves downward, it cooperates with the driving component to drive the two protective cases 3 to close, thereby closing the top of the charging device, avoiding or reducing the accumulation of some dust and bird droppings on the top of the landing pad 4, and effectively improving the practicability of the unmanned aerial vehicle charging device.

[0028] The driving component includes driving toothed plates 22 on the left and right sides. The driving toothed plates 22 on the left and right sides are respectively fixedly connected to the left and right end faces of the landing pad 4. On the left and right sides inside the bottom case 1, two groups of driving gears 21 are rotatably installed through rotating shafts. The end portions of the rotating shafts on the driving gears 21 rotatably extend outside the bottom case 1, and the end portions of the rotating shafts of the driving gears 21 extending outside the bottom case 1 are fixedly connected to the inner walls of the corresponding protective cases 3.

[0029] When the electric push rod 11 drives the landing pad 4 to move downward, the landing pad 4 will drive the two driving toothed plates 22 to move downward. The driving toothed plates 22 are engaged with the driving gears 21. When the driving toothed plates 22 move downward, they will drive the driving gears 21 to rotate. When the driving gears 21 rotate, they drive the protective cases 3 to rotate through the rotating shafts connected to their ends, thereby closing the top of the landing pad 4.

[0030] A fixing frame 20 is sleeved outside the driving toothed plate 22. The fixing frame 20 is fixedly connected to the inner wall of the bottom case 1. A sliding groove 18 is formed on the driving toothed plate 22, and a sliding block 19 is slidably connected to the sliding groove 18. The sliding block 19 is fixedly connected to the fixing frame 20.

[0031] When the driving toothed plate 22 moves up and down, the sliding block 19 will slide along the sliding groove 18, enabling the landing pad 4 to move up and down stably.

[0032] The positioning component includes two groups of first positioning plates 5 and two groups of second positioning plates 7. First sliding openings 6 are provided on both the left and right sides of the upper end surface of the apron platform 4, and second sliding openings 8 are provided on both the front and rear sides of the upper end surface of the apron platform 4. A first sliding plate 17 is slidably connected to the first sliding opening 6, and the first positioning plate 5 is fixedly connected to the top of the first sliding plate 17. A second sliding plate 13 is slidably connected to the second sliding opening 8, and the second sliding plate 13 is fixedly connected to the second positioning plate 7. A first transmission toothed plate 12 is fixedly connected to the first sliding plate 17, and a second transmission toothed plate 16 is fixedly connected to the second sliding plate 13. A transmission rod 26 is rotatably installed on the cross-shaped body 15. The top end of the transmission rod 26 is fixedly connected to a first transmission gear 24, and the first transmission gear 24 meshes with the two groups of first transmission toothed plates 12. A second transmission gear 23 is fixedly sleeved on the outer surface of the transmission rod 26, and the second transmission gear 23 meshes with the second transmission toothed plate 16. A transmission mechanism for driving the transmission rod 26 to rotate is installed inside the bottom shell 1. The transmission mechanism includes a fixed toothed plate 10, and the fixed toothed plate 10 is fixedly connected inside the bottom shell 1. A connecting plate 28 is fixedly connected to the cross-shaped body 15, and a rotating rod is rotatably inserted through the connecting plate 28. One end of the rotating rod is fixedly connected to a first bevel gear 27, and a second bevel gear 25 is fixedly sleeved on the outer surface of the transmission rod 26. The second bevel gear 25 meshes with the first bevel gear 27. The other end of the rotating rod is fixedly connected to a connecting gear 14, and the connecting gear 14 meshes with the fixed toothed plate 10.

[0033] When the apron platform 4 moves downward, the connecting gear 14 will rotate along the fixed toothed plate 10. When the connecting gear 14 rotates, it will drive the first bevel gear 27 to rotate through the rotating rod. Since the second bevel gear 25 meshes with the first bevel gear 27, the driving rod 26 is driven to rotate. When the driving rod 26 rotates, it will drive the first transmission gear 24 and the second transmission gear 23 to rotate. The first transmission gear 24 meshes with the first transmission toothed plate 12, and the second transmission gear 23 meshes with the second transmission toothed plate 16. Therefore, when the driving rod 26 rotates, the two groups of first transmission toothed plates 12 will move away from or towards each other, and the two groups of second transmission toothed plates 16 will also move away from or towards each other simultaneously. Thus, when the apron platform 4 moves downward, the two groups of first positioning plates 5 will position the left and right sides of the drone, and the two groups of second positioning plates 6 will position the front and rear sides of the drone, avoiding the movement of the drone during charging, and at the same time, the drone can be located in a position close to the wireless charger.

[0034] The first transmission toothed plate 12 is located above the second transmission toothed plate 16, and the second positioning plate 7 is located above the first positioning plate 5.

[0035] Working principle: When the drone lands stably on the landing pad 4, as the landing pad 4 moves downward, the connecting gear 14 will rotate along the fixed toothed plate 10. When the connecting gear 14 rotates, it will drive the first bevel gear 27 to rotate through the rotating rod. Since the second bevel gear 25 meshes with the first bevel gear 27, it will drive the driving rod 26 to rotate. When the driving rod 26 rotates, it will drive the first transmission gear 24 and the second transmission gear 23 to rotate. The first transmission gear 24 meshes with the first transmission toothed plate 12, and the second transmission gear 23 meshes with the second transmission toothed plate 16. Therefore, when the driving rod 26 rotates, the two groups of first transmission toothed plates 12 will move away from or towards each other, and the two groups of second transmission toothed plates 16 will also move away from or towards each other simultaneously. Thus, when the landing pad 4 moves downward, the two groups of first positioning plates 5 will position the left and right sides of the drone, and the two groups of second positioning plates 6 will position the front and rear sides of the drone, preventing the drone from moving during charging. At the same time, it keeps the drone and the wireless charger 9 at the bottom of the landing pad 4 in close proximity, ensuring stable signal transmission and avoiding unstable signals caused by a relatively large distance between the drone and the wireless charger 9;

[0036] When the electric push rod 11 drives the landing pad 4 to move downward, the landing pad 4 will drive the two groups of driving toothed plates 22 to move downward. The driving toothed plates 22 mesh with the driving gear 21. When the driving toothed plates 22 move downward, they will drive the driving gear 21 to rotate. When the driving gear 21 rotates, it drives the protective shell 3 to rotate through the rotating shaft connected to its end. Thus, the top of the landing pad 4 can be closed, and the top of this charging device can be closed, avoiding or reducing the accumulation of some dust and bird droppings on the top of the landing pad 4, effectively improving the practicability of this unmanned aerial vehicle charging device.
