The retractable double-damping undercarriage comprises a mounting frame, a retractable mechanism is arranged on the mounting frame, the retractable mechanism comprises two movable frames, first connecting bases are fixedly connected to the two sides of the lower surface of the mounting frame, first connecting shafts are rotatably inserted into the first connecting bases in a penetrating mode, and second connecting bases are fixed to one sides of the movable frames; a second connecting shaft is rotationally connected to the second connecting base in a penetrating mode, a connecting rod is fixedly connected to the second connecting shaft in a penetrating mode, a movable mechanism is arranged at the top of the connecting rod, and a damping mechanism is arranged between the two movable frames. Through operation of a bidirectional air cylinder, two piston rods drive two mounting rods to move towards the two sides, a fixing block drives a fixing base and the top of a connecting rod to move horizontally, the bottom of the connecting rod pulls a movable frame upwards and drives the movable frame to rotate, the movable frame and rolling wheels are convenient to retract and release, and take-off and landing of a flying model airplane are convenient; and damage caused by falling impact can be weakened.
本发明公开了一种飞行航模的可收放双减震起落架,包括安装架,安装架上设置有收放机构,收放机构包括两个活动架,安装架下表面的两侧均固定连接有连接座一,连接座一上转动穿插有连接轴一,活动架的一侧固定有连接座二,连接座二上转动穿插连接有连接轴二,连接轴二上固定穿插连接有连接杆,连接杆的顶部设置有活动机构,两个活动架之间设置有减震机构。本发明通过双向气缸的运行,使得两个活塞杆带动两个安装杆向两侧移动,固定块带动固定座和连接杆的顶部进行平移,使得连接杆的底部向上拉动活动架,带动活动架进行转动,方便对活动架和滚轮进行收放,便于飞行航模的起飞和降落,并且可以减弱降落撞击造成的损伤。
