The fixed-wing model airplane undercarriage folding and unfolding device with the self-locking structure comprises a landing frame cabin, an undercarriage and a landing mechanism, an opening is formed in the bottom of the landing frame cabin, a driving motor of the landing mechanism is fixed to the outer side of a mounting base, a lead screw of a lead screw assembly is mounted on an output shaft of the driving motor, and the lead screw assembly is connected with the landing frame cabin. The nut is matched with the lead screw, and the outer wall of the nut extends to form a driving lever part; the end part of the undercarriage is fixedly connected with the undercarriage fixing pile, the mounting seat is fixedly connected in the cavity of the landing rack cabin, a first slide way matched with the driving lever part of the nut is formed in the mounting seat, the middle part of the undercarriage fixing pile is hinged with the mounting seat, and a second slide way matched with the driving lever part of the nut is formed in the undercarriage fixing pile. The reset tension spring is matched with the hook rod, the landing gear supporting rod makes contact with and acts on the pressure spring arms on the two sides when falling to press the pressure spring arms downwards, and the pressure spring arms are connected with the landing gear cabin door through the hook rod, so that the cabin door can be closed together when the pressure spring arms on the two sides fall to achieve the effect of closing the cabin door.

    本发明给出了一种具有自锁结构的固定翼航模起落架收放装置,包括落架舱、起落架和起落机构,所述落架舱底部设有开口,起落机构的驱动电机固定在安装座外侧,丝杠组件的丝杆安装在的驱动电机的输出轴上,螺母与丝杠配合且螺母外壁延伸有拨杆部;起落架端部与起落架固定桩固定连接,安装座固定连接在落架舱的空腔内,安装座上开有与螺母的拨杆部配合的第一滑道,起落架固定桩中部与安装座铰接,起落架固定桩开有与螺母的拨杆部配合的第二滑道。采用复位拉簧与挂钩杆配合,通过起落架支撑杆下落时接触并作用于两边压簧臂,将压簧臂下压,由于压簧臂通过挂钩杆与起落架舱门相连,所以在两边压簧臂下落时舱门也会一起闭合达到关闭舱门的效果。
