Abstract

The invention discloses a multi-rotor unmanned aerial vehicle emergency parachuting device with an adaptive ejection angle adjustment function and a method. The device comprises a parachute cabin, a parachute cabin cover, a parachute, a parachute throwing spring, a lock bolt, an unlocking steering engine, a microcontroller, an inertial motion measuring unit and a spring support rotating device. The parachute cabin cover is fixed to the parachute cabin under the combined action of the unlocking steering engine and the lock bolt, and the parachute cabin is fixed to a multi-rotor unmanned aerial vehicle; the parachute, the parachute throwing spring, the microcontroller, the inertial motion measuring unit and the spring support rotating device are arranged in a structure formed by the parachute cabin and the parachute cabin cover; the microcontroller is connected with the unlocking steering engine, the inertial motion measuring unit and the spring support rotating device, one end of the parachute throwing spring is fixed to the spring support rotating device, and the other end of the parachute throwing spring is fixed to the parachute. By adaptively adjusting the spring ejection angle, it can be guaranteed that the parachute is ejected vertically upwards even when the posture of the multi-rotor unmanned aerial vehicle has large deflection or inclination.
