[0034] Example 1
[0035] In the prior art, UAV parachute devices are mostly used in fixed-wing aircraft. The first type is a manual trigger type, which requires the operator to determine the need to land when the parachute is opened; the second type is a runaway protection type, which controls After the device detects that the remote control signal is lost, it enters the parachute procedure. However, for multi-rotor drones that do not have the ability to gliding, the parachute device used for fixed-wing drones is difficult to effectively and timely enter the parachute state to protect the aircraft in the unique emergency situations of multi-rotor drones.
[0036] The emergency parachute landing device for multi-rotor drones in this embodiment is as follows figure 1 with 2 As shown, it includes the lock bolt 1, the parachute 2, the parachute bin cover 3, the parachute bin 4, the parachute spring 5, the measurement and control unit (including the built-in lithium battery) 6, and the...
