The invention discloses a shape memory alloy-based aerocar wing active folding mechanism, which realizes folding or unfolding of aerocar wings through cooperation of a plurality of rotating wheels and a plurality of memory alloy wires. When the aerocar needs to fold the wings, the memory alloy wires are electrified and heated according to a certain sequence, so that the memory alloy wires are shrunk, the folding mechanism is pulled to rotate by a certain angle, the wings are driven to rotate by a certain angle, and the purpose of folding the wings is achieved; when the hovercar needs to take off, the folding mechanism rotates in the opposite direction by heating the memory alloy wire on the other side, the wings are unfolded and locked under the combined action of gravity, and unfolding of the wings is achieved. The flying car wing active folding mechanism based on the shape memory alloy is simple in structure, heavy and complex hydraulic systems or motors do not need to be added, the weight of a flying car is greatly reduced, and lightweight development of the flying car is promoted.
本发明公开了一种基于形状记忆合金的飞行汽车机翼主动折叠机构,通过多个转轮及多个记忆合金丝的配合,实现飞行汽车机翼的折叠或展开。在飞行汽车在需要折叠机翼时,对记忆合金丝以一定顺序,进行通电加热,使记忆合金丝收缩,从而拉动折叠机构旋转一定角度,带动机翼旋转一定角度,达到折叠机翼的目的;当飞行汽车需要起飞时,则通过加热另一边的记忆合金丝来达到折叠机构的反方向旋转,在重力的共同作用下,机翼展开并锁死,实现了机翼的展开。本发明提供基于形状记忆合金的飞行汽车机翼主动折叠机构的折叠机构由于结构简单,不需要加入沉重复杂的液压系统或电机,大大减轻了飞行汽车的重量,推动了飞行汽车轻量化发展。
