Description

technical field [0001] The invention relates to the field of supporting equipment for drones, in particular to a universal charging device for drones. technical background [0002] Due to its flexibility and ease of use, drones are increasingly used in civil, industrial, and military fields, such as aerial photography, surveying and mapping, and agricultural plant protection. The power device of drones is generally divided into electric drive and internal combustion engine drive. Compared with internal combustion engine drive, electric drive has a lower cost, lower failure rate and more convenient use, so it is widely used. The drone is driven by electricity, and the battery is the prerequisite to ensure the normal operation of the drone. Therefore, when the battery of the drone is out of power, the user needs to use a charger to charge the battery. The voltages of existing drone batteries are generally representative of 12V, 24V, and 36V, so batteries of different voltages...

AI Technical Summary

Problems solved by technology

[0003]The existing UAV battery charger only has the function of outputting one voltage to charge the battery. For users, the power output by the charger can also ensure the normal charging of the battery; but for users with a large number of UAV batteries with different voltages, it is necessary to equip a large number of chargers with different output voltages. In this way, not only the large number of chargers with different voltage outputs will lead to a large cost investment, but also occupy more installation space. In practical applications, if a charger with a voltage output occurs After a failure, the battery of the drone with a corresponding voltage cannot be charged with other chargers with different voltage outputs (the output voltage of other chargers does not match the voltage of the battery)

To sum up, the existing UAV chargers cannot adapt to output multiple voltages to charge UAV batteries with different voltages, and the application range is limited.
