Abstract
The utility model belongs to unmanned aircraft parachute descent recovery system technical field, relates to a kind of magnetic force torsion spring for umbrella hatchcover.It is characterized in that: comprise two pieces of powerful alnico magnets; Two pieces of powerful alnico magnets are separately fixed on hatchcover and umbrella hatchcover; And two pieces of alnico magnets arrange by the mode of homopolar-repulsion.Under regular flight condition, umbrella hatchcover is lockable; Under recovery state, umbrella hatchcover unlocks, and under the effect of two pieces of powerful alnico magnets homopolar-repulsions, umbrella hatchcover is opened, and recorery parachute is dished out from umbrella cabin, completes unmanned plane and reclaims.
Description
Technical field
The utility model belongs to unmanned aircraft parachute descent recovery system technical field, relates to a kind of unmanned plane umbrella hatchcover opening device.
Background technology
In unmanned plane removal process, umbrella hatchcover unlock, in the rotating shaft of umbrella hatchcover torsion spring effect under, umbrella hatchcover is opened, and recorery parachute is dished out from umbrella cabin, complete unmanned plane reclaim.
Conventional torsion spring is installed in the umbrella hatchcover rotating shaft of existing unmanned plane, there is the deficiencies such as volume is large, umbrella hatchcover unlatching moment is little.
Utility model content
The purpose of this utility model is: provide a kind of install simple, volume is little and umbrella hatchcover opens the large umbrella hatchcover opening device of moment.
For a magnetic force torsion spring for umbrella hatchcover, it is characterized in that: comprise two pieces of powerful alnico magnets; Two pieces of powerful alnico magnets are separately fixed on the umbrella cabin of hatchcover and fuselage; And two pieces of alnico magnets arrange by the mode of homopolar-repulsion.
The magnetic force torsion spring of described umbrella hatchcover, is characterized in that: two pieces of powerful alnico magnets are installed on rotating shaft far-end or near-end, larger from the larger unlatching moment of rotating shaft distance.
The magnetic force torsion spring of described umbrella hatchcover, is characterized in that: under regular flight condition, umbrella hatchcover is lockable; Under recovery state, umbrella hatchcover unlocks, and umbrella hatchcover is opened by two pieces of powerful alnico magnets under the effect of homopolar-repulsion.
