Unmanned aerial vehicle parachute automatic opening device

Abstract

An unmanned aerial vehicle parachute automatic opening device is composed of a bullhead framework fixed inside a vehicle body, a parachute cabin cover capable of automatically bouncing up, a parachute cabin in matched connection with the parachute cabin cover, a steering engine, a driving shaft, a steering engine rocker arm and a steering engine fixing platform. The unmanned aerial vehicle parachute automatic opening device is characterized in that the bullhead framework is fixed inside the vehicle body, the steering engine fixing platform is arranged at the top of the bullhead framework, the parachute cabin is arranged on one side of the bullhead framework, one end of the parachute cabin is movably connected with one end of the parachute cabin cover, and the other end of the parachute cabin cover is coincidently matched with the side portion of the steering engine fixing platform; the steering engine is fixed on the inner side of the steering engine fixing platform, and the driving shaft arranged on the steering engine is connectedly fixed to the steering engine rocker arm through the steering engine fixing platform. The unmanned aerial vehicle parachute automatic opening device has the advantages that space inside the unmanned aerial vehicle body is fully utilized to contain an unmanned aerial vehicle parachute, so that convenience is brought to filling and opening of the parachute; air resistance generated by a parachute cabin cover opening driving device is reduced to greatest extent.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a novel automatic parachute opening device for unmanned aerial vehicles. Make full use of the internal space of the UAV body to fill the UAV parachute to facilitate the filling and opening of the parachute; minimize the air resistance generated by the umbrella hatch cover opening drive device. Background technique [0002] Chinese Patent No. 2012201954475 discloses a push-back micro unmanned aircraft drop-down soft-connection hatch cover opening device, including an umbrella cabin, a parachute and an umbrella hatch cover, and a plug is provided at one end of the drone hatch cover to connect the drone The fuselage is provided with a groove corresponding to the plug at one end of the umbrella cabin of the unmanned aircraft. The plug is inserted into the groove of the umbrella cabin, and the other end of the umbrella cabin is provided with a slot for the steering ...

Problems solved by technology

[0003] Chinese patent application number 201610221449X discloses a separate parachute ejection chamber for drones, which relates to the field of parachute recovery technology for drones, and solves the problem of entanglement between the parachute and the fuselage structure of the existing drone parachute, and the opening of the parachute out of the cabin. If the parachute is not in time, it will lead to parachute failure and problems such as fuselage, parachute, and main parachute entanglement, including the main parachute compartment, parachute compartment, parachute cover, ejection spring, ejection plate, unlocking mechanism and connecting mechanism; The parachute compartment is arranged obliquely inside the main parachute compartment, and the cover of the parachute compartment is movably connected with the main parachute compartment through a connecting mechanism; the ejection plate compresses the ejection spring into the parachute compartment and locks it through the ejection lock cylinder of the unlocking mechanism; After the parachute is ejected out of the cabin through the unlocking mechanism and deployed, the main parachute can be towed out of the cabin
