The invention discloses a variable-thickness wing which comprises a wing main body and a cam connecting rod mechanism, the section of the wing is divided into six sections, and the cam connecting rod mechanism is designed to drive each part of the wing to move after the wing is endowed with a deformation degree of freedom. A cam connecting rod mechanism is a common mechanical transmission device, is used for converting rotary motion into linear motion, and consists of a cam, a connecting rod and a crankshaft. The rotation of the cam drives the whole wing to reciprocate. And the convex part of the cam head can push the connecting rod, so that the connecting rod presents different positions and angles so as to drive the wing to deform. The motor is connected with the center of the cam to realize automatic operation of wing deformation. The device is simple in structure and convenient to manufacture and maintain; through the design and control of the cam, accurate position control and motion trail can be realized; the thickness and camber change of the whole wing can be realized by controlling the rotation of a single motor, and the surface of the wing frame in the deformation process is relatively smooth without obvious turning.

    本发明公开一种变厚度机翼,包括机翼主体和凸轮连杆机构,将机翼剖面分为六段,赋予其变形自由度后,设计凸轮连杆机构带动机翼各部分移动。凸轮连杆机构是一种常见的机械传动装置,用于将旋转运动转化为线性运动,它由凸轮、连杆和曲轴组成。凸轮的旋转会带动整体机翼进行往复运动。凸轮头的凸起部分会推动连杆,使连杆呈现出不同的位置和角度从而带动机翼的变形。电机与凸轮中心相连即可实现机翼变形的自动化操作。本发明结构简单,方便制造与维护;通过凸轮的设计与控制可以实现精准的位置控制和运动轨迹;通过控制单个电机的转动即可实现整体机翼的厚度及弯度变化且变形过程中机翼框架表面较为光顺,无明显转折。
