Embodiment 1
[0035] In the prior art, UAV parachute devices are mostly used in fixed-wing aircraft. The first type is the manual trigger type, which requires the operator to issue a command to open the parachute when it is necessary to determine the landing; the second type is the out-of-control protection type. After the device detects that the remote control signal is lost, it enters the parachute procedure. However, for multi-rotor UAVs that do not have the ability to glide, the parachute device used for fixed-wing UAVs is difficult to effectively and timely enter the parachute state to protect the aircraft in emergencies unique to multi-rotor UAVs.
[0036] The emergency parachute device for multi-rotor UAV described in this embodiment, such as figure 1 and 2 As shown, it includes lock bolt 1, parachute 2, umbrella compartment cover 3, umbrella compartment 4, parachute throwing spring 5, measurement and control unit (including built-in lithium battery) 6, and unlocking steering gear 7...
