Miniature retractable undercarriage

Abstract

This application relates to the field of model aircraft technology, and in particular to a miniature retractable undercarriage. The miniature retractable undercarriage comprising: a fixed frame body, in the fixed frame body, a drive assembly accommodating cavity and a control assembly accommodating cavity are provided transversely in sequence; a control assembly including a rotating member rotatably disposed within the control assembly accommodating cavity, and a control member sleeved around the outer periphery of the rotating member, wherein the control member is connected to the rotating member via a screw pair; an undercarriage, whose control end being rotatably connected to the control assembly accommodating cavity, wherein the tip of the control end of the undercarriage features a guide slot that cooperates with the control member sliding on the rotating member, thereby driving the undercarriage to rotate about the control end; a drive assembly configured within the drive assembly accommodating cavity and fixedly connected to the rotating member. Under this structure, the fixed frame body of the present application can achieve an ultra-thin design (7.7 mm in thickness), making it suitable for model aircraft weighing less than 400 g.
