The model airplane brake parachute system comprises a parachute pack cover plate, an unlocking assembly and a steering engine, the steering engine can control a rocker arm to push the unlocking assembly to leave the parachute pack cover plate, the unlocking assembly comprises a switch push block, a rotating shaft, a rotating piece and a torsional spring, and a switch mounting groove is formed in the switch push block; the rotating piece is matched with the rotating shaft to be installed in the switch installation groove in a swinging mode, a torsion spring installation groove is formed in the top of the rotating piece, the rotating shaft penetrates through the torsion spring installation groove, the torsion spring is matched with the rotating shaft to be arranged in the torsion spring installation groove, a torsion arm of the torsion spring abuts against the groove bottom of the torsion spring installation groove, and the torsion arm pushes the rotating piece to abut against one side of the switch installation groove. According to the model airplane brake parachute system, a rocker arm is controlled by a steering engine to push an unlocking assembly to unlock a parachute pack cover plate, and the unlocking assembly automatically resets under the action of a reset spring. Through the ingenious mechanical structure design, the brake parachute pack can be installed without resetting the rocker arm, and the use experience of a user is improved.
本发明涉及一种航模减速伞系统,包括伞包盖板、解锁组件以及舵机,所述舵机可控制摇臂推动解锁组件离开伞包盖板,所述解锁组件包括开关推块、转轴、旋转件以及扭簧,所述开关推块上设有开关安装槽,所述旋转件配合转轴可摆动式安装于开关安装槽内,所述旋转件的顶部设有扭簧安装槽,所述转轴贯穿扭簧安装槽,扭簧配合转轴设置于扭簧安装槽内,所述扭簧的扭臂抵于扭簧安装槽的槽底,扭臂推动旋转件抵于开关安装槽一侧。本发明中涉及一种航模减速伞系统,通过舵机控制摇臂推动解锁组件解除与伞包盖板锁定,解锁组件在复位弹簧作用下自动复位。本发明通过巧妙的机械结构设计无需先将摇臂复位后才能安装减速伞包,提高用户的使用体验。
