DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0029] Reference Figures 1 to 2 The present invention provides an embodiment of a wireless charging station for drones, comprising a charging platform 1 and a drone 12. The charging platform 1 is a planar structure with a square shape. The charging platform 1 is made of a durable stainless steel shell to ensure that it can withstand the weight of the drone 12 and various environmental conditions. A motor 7 is fixedly connected to the interior of the charging platform 1. The main function of the motor 7 is to provide a power source to drive the subsequent structure to slide back and forth and adjust the position. The driving end of the motor 7 is fixedly connected to a screw 8. The external thread of the screw 8 is connected to a guide rail 9. The main function of the screw 8 is to convert the rotational motion of the motor 7 into the spiral motion of the guide rail 9. By cooperating with the internal thread of the guide rail 9, the guide rail 9 can be moved back and forth. The guide rail 9 is internally rotatably connected to a screw rod 2 11, which is perpendicular to the direction of the screw rod 1 8 and drives the subsequent structure to move left and right to adjust the position through rotation. The guide rail 9 is internally fixedly connected to a motor 2 10, which has the same function as the motor 1 7 and provides a power source for adjusting the other direction through rotation. The external thread of the screw rod 2 11 is connected to a nut block 13, which is usually a block structure. The nut block 13 can be adjusted to any position in the horizontal direction through the guide rail 9 and the screw rod 2 11 at the bottom, thereby achieving the effect of precise wireless charging. A lifting component for lifting the wireless charging structure is provided on the top of the nut block 13.
[0030] Reference Figure 2 The outer part of the guide rail 9 is slidably connected to the inside of the charging platform 1, and the guide rail 9 is limited by the internal space of the charging platform 1, so that the spiral motion is limited and only sliding is allowed. The outer part of the nut block 13 is slidably connected to the inside of the guide rail 9, and the nut block 13 is also limited by the inner wall of the guide rail 9, so that the nut block 13 can only slide, thereby adjusting the position of the subsequent wireless charging structure.
[0031] Reference Figure 1 and Figure 4 A cable conduit 2 is fixedly connected to the front of the charging platform 1. This conduit 2 is typically a cylindrical tubular structure. Its primary function is to protect and organize the cables connecting the charging platform 1 to the subsequent control structure, preventing them from becoming tangled and disorganized. It also provides some protection from external forces, protecting the cables from damage. A control system 3 is fixedly connected to the front of the conduit 2. This control system 3 is the core component of the entire wireless charging station, responsible for controlling various charging parameters such as charging power, charging time, and motor operation. The electronic components within control system 3, through sophisticated circuit design and programming, enable precise control of the charging platform 1 and drone 12. A power module 4 is fixedly connected to control system 3. Its primary function is to provide power to the entire wireless charging station. It converts external power to a voltage and current suitable for the charging platform 1 and drone 12, or it can directly power the system using its internal battery pack. A GPS antenna 5 is fixedly connected to the top of control system 3. Its primary function is to receive Global Positioning System (GPS) signals and provide location information to the wireless charging station. Using the GPS antenna 5, the control system 3 can determine the location of the charging platform 1 and transmit this location information to the drone 12, enabling it to accurately locate the charging platform 1 for charging. A fixed anemometer 6 is attached to the top of the control system 3. Its primary function is to measure ambient wind speed. It monitors wind speed in real time and transmits this information to the control system 3. The control system 3 can adjust the position and posture of the charging platform 1 or suspend charging operations based on wind speed conditions to ensure the safety of the drone 12 and the charging system. A drone energy receiving coil 20 is fixed to the bottom of the drone 12. When the drone 12 lands on the charging platform 1, the wireless charging structure on the charging platform 1 generates an electromagnetic field. This electromagnetic field induces a current in the drone energy receiving coil 20, charging the drone 12's battery. A fixed payload 21 is attached to the top of the drone 12. This payload 21 provides the necessary functions and equipment for the drone 12 to perform specific tasks. For example, a camera can be used to capture photos and videos, sensors can be used to measure environmental parameters, and a cargo hold can be used to transport cargo.
[0032] Reference Figures 2 to 3 The lifting assembly includes a fixed base 16, the bottom of which is fixedly connected to the top of the nut block 13. The main function of the fixed base 16 is to provide a stable installation base and lifting support point for the scissors frame 17. The internal rotation of the fixed base 16 is connected to the scissors frame 17. The scissors frame 17 is usually composed of a plurality of cross-connected rods, and its shape is similar to the cross structure of scissors. The main function of the scissors frame 17 is to realize the lifting and lowering of the drone energy transmitting coil 19 by changing its own shape. The top of the scissors frame 17 is rotatably connected to the drone energy transmitting coil 19. The main function of the drone energy transmitting coil 19 is to transmit wireless charging energy to the drone energy receiving coil 20. When the drone 12 lands on the charging platform 1, the drone energy transmitting coil 19 transmits electrical energy to the drone 12 through electromagnetic coupling with the drone energy receiving coil 20 to charge its battery. The top of the nut block 13 is fixedly connected to a fixed slide 14, and the interior of the fixed slide 14 is slidably connected to a sliding rod 15. The main function of the sliding rod 15 is to move along the fixed slide 14, thereby changing the shape of the scissor frame 17 and achieving the lifting and lowering of the drone energy transmitting coil 19. The external rotation of the sliding rod 15 is connected to an electric push rod 18, and the driving end of the electric push rod 18 is rotatably connected to the outside of the scissor frame 17. The main function of the electric push rod 18 is to push the sliding rod 15 along the fixed slide 14 by extending and retracting the push rod, thereby changing the shape of the scissor frame 17 and achieving the fit between the drone energy transmitting coil 19 and the drone energy receiving coil 20 for wireless charging.
[0033] Working principle: First, the operator controls the drone 12 to land on the top surface of the charging platform 1, and turns on the power switch of motor 17 to drive screw 18 to rotate, thereby driving the guide rail 9 to generate spiral motion. Since the guide rail 9 is limited by the charging platform 1, only the guide rail 9 is allowed to slide, and the front and rear positions of the guide rail 9 are adjusted. At this time, the power switch of motor 2 10 is turned on again, and the driving end of motor 2 10 drives screw 2 11 to rotate, driving the nut block 13 to slide inside the guide rail 9, and adjusting the position of the nut block 13 and the drone energy transmitting coil 19 on the top. The position of the drone energy transmitting coil 19 is adjusted through the control system 3 so that the drone energy transmitting coil 19 can be moved to a position connected to the drone energy receiving coil 20, which solves the safety hazards such as leakage and short circuit in the existing technology due to wired charging of the drone 12. Wireless charging can avoid these problems and reduce the risk of accidents during the charging process of the drone 12.
[0034] Secondly, the power switch of the electric push rod 18 is turned on again. The driving end of the electric push rod 18 is retracted to generate a reaction force, which drives the sliding rod 15 to slide to the left, thereby driving the scissor frame 17 to rotate and extend as a whole, raising the drone energy transmitting coil 19 on the top to contact the drone energy receiving coil 20 at the bottom of the drone 12, so that the drone energy transmitting coil 19 and the drone energy receiving coil 20 are connected to realize wireless charging of the drone 12. It can realize fully automated and intelligent charging without any need. The operator only needs to land the drone 12 within the charging range to realize wireless charging, eliminating the process of removing the battery for charging the traditional drone 12, and achieving senseless intelligent charging.
[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
