Description

Technical Field

[0001] The present invention relates to the technical field of UAV power supply, and specifically to a voltage-stabilized dual-battery UAV power supply device with a self-switching circuit module. Background Art

[0002] At present, when UAVs are widely used in many fields, the optimization of their power supply systems has become a key link in technological development. The traditional power supply methods for UAVs face many challenges and limitations. From the perspective of battery materials and preparation processes, the previous cathode materials are difficult to meet the stringent requirements of UAVs for high energy density and long endurance. Conventional preparation methods cannot effectively improve the performance of cathode materials, and there is a lack of systematic and comprehensive performance evaluation means, resulting in limited energy conversion efficiency and stability of the batteries. For example, in lithium-carbon monofluoride system batteries, the cathode materials prepared by traditional processes have obvious deficiencies in power output and cycle life, which limits their further application in the field of UAVs. In terms of power supply modes, single lithium battery power supply or simple battery combination power supply can no longer adapt to complex and changeable flight tasks. On the one hand, when the power of a single-power-supply UAV runs out or the battery suddenly fails, it is extremely easy to lose power and crash, seriously endangering flight safety and mission execution. On the other hand, the traditional power supply system lacks effective utilization of renewable energy and cannot fully collect and convert solar energy into electrical energy in an environment with sufficient sunlight, resulting in energy waste and failure to extend the endurance time of the aircraft. In response to these problems, the present invention has carried out a series of innovative researches. First, the chemical reduction method is innovatively used to prepare Ag-coated carbon monofluoride cathode materials, and the preparation technology of carbon monofluoride / manganese dioxide composite cathodes is deeply explored. A perfect cathode performance evaluation system is established. At the same time, the preparation and encapsulation processes of lithium-carbon monofluoride system UAV batteries are carefully studied, and comprehensive and systematic performance comprehensive tests and evaluations are carried out, greatly improving the energy density and stability of the batteries. Second, a backup power supply system with a lithium battery - monocrystalline silicon solar panel as the core is introduced to construct a dual-power supply architecture. With the help of the MPPT module, the working point of the solar panel is adjusted in real time and accurately to achieve maximum power point tracking, ensuring stable and efficient charging efficiency under different light intensities, making full use of solar energy resources, and effectively extending the endurance mileage of the UAV. Finally, an intelligent power switching module is designed, which can flexibly switch between high specific energy batteries and traditional lithium batteries. It can not only charge the lithium battery with solar energy during the power supply period of the high specific energy battery to achieve reasonable distribution and reserve of energy, but also when one power supply fails, the system can quickly and automatically switch to the backup power supply to ensure the continuous and stable operation of the UAV, significantly improving the reliability and adaptability of the UAV power supply system, and providing a solid power guarantee for the long-term and efficient operation of UAVs in complex environments.

[0005] Preferably, the end of the electrode contact column facing the power supply semi-ring is hemispherical in design, and both ends of the power supply semi-ring are arranged with arc chamfers, the power supply semi-ring is a double-layer design, and the two layers of the power supply semi-ring do not contact each other, a spring is connected between the electrode contact column and the outer surface of one end of the power supply battery, and the electrode contact column and the outer surface of one end of the power supply battery are slidably connected, and the electrode contact column and the electrode of the power supply battery are electrically connected through a cable, and the outer surface of the electrode contact column fits the outer surface of the power supply semi-ring.

[0006] By adopting the above technical solution, the hemispherical design of the electrode contact column cooperates with the arc chamfer and double-layer structure of the power supply half ring, which is conducive to smooth contact and disconnection when the battery is switched. The spring connection enables the electrode contact column to adapt to position changes, ensuring contact stability and power transmission.

[0007] Preferably, the limit block is designed as a right-angle trapezoid, and the inclined surface of the limit block surface is arranged toward the clearance groove, and a spring is connected between the limit block and the mounting seat, and the outer surface of one end of the limit block fits with the outer surface of the power supply battery.

[0008] By adopting the above technical solution, the right-angled trapezoidal limit block can effectively limit and buffer the battery during the battery installation and switching process with the help of the inclined surface and the spring to prevent the battery from excessive displacement.

[0009] Preferably, the limit plate is frictionally connected to the mounting seat, and one end of the limit plate located inside the mounting seat is penetrated by the limit rod, and the limit plate is slidably connected to the limit rod.

[0010] By adopting the above technical solution, the sliding friction connection between the limiting plate and the mounting seat and the cooperation with the limiting rod can stably limit the battery in the other direction of the mounting seat to ensure that the battery is firmly installed.

[0011] Preferably, the two ends of the communicating groove respectively penetrate the piston cavity and the internal cavity of the mounting seat where the limit plate is located, and the piston cavity and the piston block are connected by sliding friction.

[0012] By adopting the above technical solution, the connecting groove connects the piston cavity with the cavity where the limit plate is located. Combined with the sliding friction connection between the piston block and the piston cavity, it provides a basis for air pressure transmission for subsequent driving of related components and ensures the continuity of the switching action.

[0013] Preferably, the sliding frame is slidably connected to the mounting seat via a sliding rod, the sliding frame is rotationally connected to the adjusting rod, and the adjusting rod is threadedly connected to the mounting seat.

[0014] By adopting the above technical solution, the connection method between the sliding frame, the sliding rod and the adjusting rod is such that when the adjusting rod rotates, the sliding frame can be driven to translate, thereby driving the piston block to move, thereby realizing indirect control of components such as the driving gear and accurately adjusting the switching action.

[0015] Preferably, the driving gear rod is meshingly connected with the driving gear, and the driving gear and the pressure wheel are concentrically designed. The pressure wheel is a special-shaped wheel made of rubber material, and the diameters of the two ends of the pressure wheel are different.

[0016] By adopting the above technical solution, the meshing of the driving gear rod and the driving gear realizes power transmission, and the driving gear drives the clamping wheel to rotate. The rubber material, special-shaped wheel design and different diameters at both ends can effectively clamp and guide the battery when switching the battery, ensuring good contact between the electrodes.

[0017] Preferably, a stabilizing mechanism is provided on the surface of the fixing frame, which ensures a stable connection between the power supply battery and the power supply half ring by positioning the orientation axis after the direction switching of the mounting seat is completed; The stabilizing mechanism includes: a piston cylinder fixedly arranged on the outer surface of a fixed frame, and a positioning cylinder fixedly arranged on the inner surface of the fixed frame. A connecting pipe is connected and communicated between the lower ends of the positioning cylinder and the piston cylinder. The lower end of the piston cylinder is designed to be open, and an annular electromagnet is fixedly installed inside the lower end of the piston cylinder. A sliding piston plate is installed inside the upper end of the piston cylinder, and an annular fixed magnet is fixedly arranged on the wire surface of the piston plate. One end of a positioning rod is arranged inside the upper end of the positioning cylinder, and a plug hole is formed on the outer surface of the orientation shaft opposite to the positioning rod.

[0018] With the above technical solution, the stabilizing mechanism controls the engagement of the positioning rod and the orientation shaft after the switching is completed through components such as the piston cylinder, the positioning cylinder, the connecting pipe, and the interaction between the electromagnet and the fixed magnet, realizing the precise positioning of the orientation shaft and enhancing the connection stability between the battery and the power supply semi-ring.

[0019] Preferably, the piston cylinder and the piston plate are in sliding friction connection, and the opposite ends of the fixed magnet and the electromagnet have opposite magnetic poles.

[0020] With the above technical solution, the sliding friction between the piston cylinder and the piston plate ensures the smooth movement of the piston. The opposite magnetic poles of the fixed magnet and the electromagnet provide a power basis for their relative movement, thereby driving the positioning rod to act.

[0021] Preferably, the positioning rod and the positioning cylinder are in sliding friction connection, and a spring is connected between the positioning rod and the positioning cylinder. The upper end of the positioning rod penetrates through the upper surface of the positioning cylinder, and the upper end of the positioning rod is snap-fitted with the orientation shaft through the plug hole.

[0022] With the above technical solution, the sliding friction between the positioning rod and the positioning cylinder and the spring enable the positioning rod to operate stably both in the normal state and during operation. By being snap-fitted with the orientation shaft, the position of the orientation shaft is effectively locked, ensuring the stability of the battery power supply.

[0023] Compared with the prior art, the beneficial effects of the present invention are: The voltage-stabilized dual-battery unmanned aerial vehicle power supply device of the self-switching circuit module: 1. By means of the switching use of the high specific energy battery and the lithium battery, when the lithium battery has insufficient power or fails, the switching function between the high specific energy battery and the traditional lithium battery of the switching module is utilized to realize the reasonable allocation of energy. The high specific energy battery can provide powerful power during the critical flight stage or high-energy consumption tasks, while the traditional lithium battery can play a role during daily flight or low-energy consumption tasks and reserve electric energy under solar charging. This switching mode not only optimizes the energy utilization but also ensures a stable power supply output in different flight scenarios and battery states, effectively avoiding flight interruption caused by single-battery power supply problems; 2. During the battery switching process, the electrode contact post and the power supply half ring are smoothly connected or disconnected, which reduces the situation of poor contact and ensures the stability of power transmission during the power supply switching process, thereby maintaining the stable operation of various aircraft systems. At the same time, the electrode contact post is connected to the outer surface of one end of the power supply battery through a spring and is a sliding connection. It can adapt to the position change to a certain extent to the wear of the electrode contact post itself, further ensuring good contact to ensure the stability of the power supply voltage of the power supply battery; 3. The position of the power supply battery in the mounting seat is effectively limited by the limiting component to prevent the power supply battery from shifting due to vibration and other reasons during the flight of the aircraft, ensuring that the power supply battery is always in a suitable position for normal power supply switching and other operations. At the same time, the stabilizing mechanism enhances the connection stability between the power supply battery and the power supply half ring. After the direction of the mounting seat is switched, the stabilizing mechanism plays a role. Through the structure composed of the piston cylinder, the positioning cylinder, the connecting tube and other components, the interaction between the electromagnet and the fixed magnet and the snap-fit ​​installation of the positioning rod and the plug hole on the directional shaft can accurately position the directional shaft, thereby ensuring the stable connection between the power supply battery and the power supply half ring. This ensures that during the flight, even if disturbed by factors such as airflow, the connection between the power supply battery and the power supply half ring will not be easily loosened or disconnected, thereby ensuring the reliability of power supply.

A sliding frame 12 is arranged on the side surface of one end of the mounting seat 4, and piston blocks 13 are fixedly arranged at both ends of the sliding frame 12. A sliding rod 14 and an adjusting rod 15 are respectively arranged at both ends of the sliding frame 12. A driving rack 16 is fixedly arranged on the side surface of one end of the piston block 13. A rotating driving gear 17 is installed inside the side surface of the piston chamber 10, and one end of the rotating shaft of the driving gear 17 penetrates through the outer surface of the mounting seat 4. And one end of the rotating shaft of the driving gear 17 located outside the mounting seat 4 is fixedly connected with a pressing wheel 18. A relief groove 19 is opened on the outer surface of one end of the fixing frame 1 away from the switching motor 2. A power supply semi-ring 20 is fixedly arranged on the inner surface of the fixing frame 1 where the switching motor 2 is located; One end of the electrode contact post 6 facing the power supply semi-ring 20 is designed as a hemispherical shape, and both ends of the power supply semi-ring 20 are provided with arc chamfers. The power supply semi-ring 20 is of a double-layer design, and the two layers of the power supply semi-ring 20 do not contact each other. A spring is connected between the outer surface of one end of the electrode contact post 6 and the outer surface of the power supply battery 5, and the outer surface of one end of the electrode contact post 6 is slidably connected with the outer surface of the power supply battery 5. And the electrodes of the electrode contact post 6 and the power supply battery 5 are electrically connected through a cable.

The adjusting rod 15 drives the sliding frame 12 to slide on the mounting seat 4 through the sliding rod 14 through the threaded connection with the mounting seat 4. The sliding frame 12 drives the piston block 13 to slide to the outside of the piston chamber 10.

At this time, one end of the power supply battery 5 squeezes the inclined surface of the limit block 7, and the limit block 7 slides and compresses the spring between the mounting seat 4 until the electrode contact column 6 at one end of the power supply battery 5 fits with the power supply half ring 20. At this time, the other end of the power supply battery 5 is completely moved to one side of the limit block 7, so that the limit block 7 slides and resets to limit one end of the power supply battery 5 under the support of the spring, and then the adjusting rod 15 is rotated in the opposite direction to make the piston block 13 slide toward the inside of the piston cavity 10.

And a plugging hole 28 is formed on the outer surface of the directional shaft 3 opposite to the positioning rod 27. The piston cylinder 21 and the piston plate 25 are in sliding friction connection. The opposite ends of the fixed magnet 26 and the electromagnet 24 have opposite magnetic poles. The positioning rod 27 and the positioning cylinder 22 are in sliding friction connection. And a spring is connected between the positioning rod 27 and the positioning cylinder 22. The upper end of the positioning rod 27 penetrates through the upper surface of the positioning cylinder 22. And the upper end of the positioning rod 27 is snap-fitted and installed with the directional shaft 3 through the plugging hole 28. When the switching motor 2 is powered on and started, at this time the electromagnet 24 is synchronously powered on and started. The electromagnet 24 inside the lower end of the piston cylinder 21 adsorbs the fixed magnet 26 to make the piston plate 25 slide down. The piston plate 25 drives one end of the positioning rod 27 inside the positioning cylinder 22 to slide down through pressure and the connecting pipe 23. So that the upper end of the positioning rod 27 slides down and disengages from the snap-fitting with the plugging hole 28 on the surface of the directional shaft 3. So that the switching motor 2 can smoothly drive the directional shaft 3 to rotate when starting. And after the switching motor 2 finishes working and is powered off, at this time the electromagnet 24 is powered off and ends the adsorption of the fixed magnet 26. At this time, the positioning rod 27 slides up through the plugging hole 28 under the support of the spring between the positioning rod 27 and the positioning cylinder 22 to resume the snap-fitting with the directional shaft 3, ensuring the stability of the mounting seat 4 during the flight of the drone.
