Abstract

The invention discloses an automatic parachute opening device for an unmanned aerial vehicle. The device comprises a parachute bay, a parachute bay cover, a detonator and a ratchet mechanism, whereinthe ratchet mechanism is installed on the outer wall of the parachute bay, one end of the parachute bay cover is inserted into the inner wall of the parachute bay, the other end of the parachute bay cover is connected with a nylon rope, the tail end of the nylon rope is connected with the ratchet mechanism, the ratchet mechanism is used for tensioning the nylon rope, and the detonator sleeves thenylon rope and is connected with a power supply and a flight control module. The automatic parachute opening device for the unmanned aerial vehicle is sensitive and rapid in response, opening of the parachute bay cover and unfolding of the recovery parachute can be rapidly and reliably achieved, and safe recovery of the unmanned aerial vehicle is guaranteed.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle accessories, in particular to an automatic parachute opening device for an unmanned aerial vehicle. Background technique [0002] The recovery methods of drones mainly include parachute recovery, air recovery, arresting net recovery, landing gear roll recovery and air cushion landing recovery. Compared with other recovery methods, parachute recovery has the characteristics of wide application range, high cost performance, small size, light weight, and no need for a wide and flat special landing site, so it is widely used in the recovery of drones. Using the parachute recovery method, how to ensure the smooth opening of the parachute becomes the key to the safe recovery of the drone. [0003] The recovery umbrella is located in the umbrella cabin and is covered by the umbrella cabin cover. When the drone is recovered, the umbrella cabin cover is opened, and the guide umbrella is pulled out, ...
