一种伞舱翻盖机构
By designing a parachute compartment flip-top mechanism, the parachute compartment cover is locked in a fixed position after being flipped open. The use of torsion springs and locking pins avoids interference with the parachute lines, thus solving the problem of interference between the parachute lines and the vertical tail or propeller during the drone parachute landing and recovery process, improving the recovery success rate and ease of operation.

AI Technical Summary
Technical Problem
During the parachute recovery process of a drone, the parachute lines are prone to interference with the tail or propeller, which can lead to a high risk of recovery failure.
Method used
Design a parachute compartment flip-top mechanism. After the parachute compartment cover is flipped, it is locked in a fixed position. The parachute straps are prevented from extending backward by a torsion spring and locking pin mechanism. Combined with pressure plate and screw restraint, the assembly and operation are simplified.
Benefits of technology
It effectively avoids interference between the parachute lines, vertical tail, and propeller, improves the success rate of recovery, reduces waste, lowers aerodynamic drag, and improves ease of operation.

Abstract
本发明涉及一种伞舱翻盖机构，包括舱体、伞舱盖组件、锁定安装板、爆炸螺栓、主伞包以及引导伞；锁定安装板固定在伞舱盖的一端，且锁定安装板随着伞舱盖转动，锁定安装板开有锁紧盲孔，所述舱体的开口端面设置有销盲孔和弹簧锁销，当伞舱盖盖住所述舱体的开口时，所述锁定安装板能够将所述弹簧销压在所述销盲孔中，当所述伞舱盖转动打开到预定角度时，所述锁紧盲孔对应所述弹簧锁销，使得所述弹簧锁销能够插入所述锁紧盲孔中，防止伞舱盖转动，使得所述伞舱盖保持打开状态。伞舱盖前端通过压板约束，后端通过螺钉与扭簧安装支座约束，装配简易，操作便捷。
