阅读说明：本技术 形状记忆合金致动器 (Shape memory alloy actuator ) 是由 彼得·凡维克 斯蒂芬·马修·邦廷 亚历山大·道斯特 于 2020-04-29 设计创作，主要内容包括：提供了一种被布置成驱动光圈元件的操作的形状记忆合金致动装置,该致动装置包括：光圈驱动机构,其被布置成基于输入运动打开和关闭光圈的孔径；以及至少一根形状记忆合金致动器线,其被布置成在致动器线收缩时提供所述输入运动。致动器装置可以具有低形状因数,并且可以适用于例如折叠摄像头组件和控制组件可用空间有限的其它装置。(There is provided a shape memory alloy actuation device arranged to drive operation of an aperture element, the actuation device comprising: a diaphragm driving mechanism arranged to open and close an aperture of a diaphragm based on an input motion; and at least one shape memory alloy actuator wire arranged to provide said input motion upon contraction of the actuator wire. The actuator device may have a low form factor and may be suitable for use in other devices where space available for a folded camera assembly and control assembly is limited, for example.)
