The invention discloses an automatic charging unmanned aerial vehicle hangar which comprises a time controller, a microprocessor and a solar charging module; the time controller transmits set time information to the microprocessor; the microprocessor controls opening and closing of a vehicle hangar door according to set time; when the vehicle hangar door is opened, the microprocessor controls an extension apron to stretch out of the vehicle hangar and an unmanned aerial vehicle parking on the extension apron is released for flight; and when the unmanned aerial vehicle falls onto extension apron, the pressure sensor receives pressure after the unmanned aerial vehicle falls and transmits a detected signal to the microprocessor, the microprocessor controls the extension apron to retract, and simultaneously controls the vehicle hangar door to be closed, and the unmanned aerial vehicle entering the vehicle hangar is charged through the solar charging module. The automatic charging unmanned aerial vehicle hangar is simple in structure, and has the reliability, the operability and the stability, and the situation that when the unmanned aerial vehicle finishing surveying and falls onto the vehicle hangar, the unmanned aerial vehicle can be automatically charged is ensured.
