Automatic ejection device for emergency parachute of unmanned aerial vehicle

Abstract

The invention belongs to the field of unmanned aerial vehicles, and especially relates to an automatic ejection device for an emergency parachute of an unmanned aerial vehicle. In view of the problemthat a traditional parachute of the unmanned aerial vehicle is not fully opened, when the parachute is opened, thereby affecting landing of the unmanned aerial vehicle, now a following scheme is proposed that: the automatic ejection device includes a shell with an opening at the top; the inner side wall of the bottom of the shell is fixedly sleeved by a sleeve pipe; an inner ring of the top of thesleeve pipe is sleeved by a first attraction ring; the inner ring of the sleeve pipe is provided with an electromagnet fixedly connected with the inner side of the bottom of the shell; the top of thesleeve pipe is in contact with a movable push plate; an attraction plate attracting the first attraction ring is inlaid at the bottom of the movable push plate; and an air bag is connected to the topof the movable push plate. The automatic ejection device quickly opens a cover plate at the top of the unmanned aerial vehicle, simultaneously blows air to and opens the parachute for emergency landing of the unmanned aerial vehicle, avoids blocking of the cover plate of a traditional unmanned aerial vehicle when the parachute is opened, and solves the problem that the parachute is not fully opened, thereby making the unmanned aerial vehicle land safely.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an automatic ejection device for an emergency parachute of an unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by the on-board computer. When landing, a parachute is needed to assist. The traditional UAV parachute is not fully opened when it is opened, which affects the landing of the UAV. For this reason, an emergency parachute ejection device for UAV is needed. Contents of the invention [0003] The invention proposes an automatic pop-up device for an emergency parachute of an unmanned aerial vehicle, which solves the problem that the traditional unmanned aerial vehicle parachute is not fully opened and deployed when it is opened, which affects the landi...
