The invention discloses a 4D printing amphibious propeller, and belongs to the technical field of propeller blade structure design. The propeller comprises a propeller hub and deformable blades; the multiple deformable blades are evenly arranged in the circumferential direction and fixedly installed on the propeller hub, the deformable blades are formed through 4D printing, heating parts are arranged in the deformable blades, after the temperature of the heating parts rises, blade materials deform, when the deformable blades work underwater, the shapes of the deformable blades are consistent with those of common blades, and when the deformable blades work on land, the deformable blades are not prone to deformation. The deformable blade is divided into two sections which are reversely bent and unfolded to form a paddle leg structure, and the paddle leg structure is driven by the propeller hub to complete the land walking function. According to the invention, the state conversion of the propeller from underwater driving to land walking can be realized, and the propulsion noise of the propeller can be effectively reduced during underwater driving.

    本发明公开了一种4D打印水陆两栖螺旋桨,属于螺旋桨桨叶结构设计技术领域。螺旋桨包括浆毂和可变形叶片;多个可变形桨叶沿圆周方向均匀布置且固定安装在桨毂上,可变形叶片通过4D打印成型,可变形叶片内部具有加热部件,加热部件温度升高后使得叶片材料发生形变,在水下工作时,可变形叶片的外形与普通叶片一致,在陆地工作时,可变形叶片的分为两瓣反向弯曲展开后形成桨腿结构,桨腿结构在桨毂的带动下完成陆地行走功能。本发明能够实现螺旋桨从水下驱动到陆地行走的状态转换,水下驱动时可有效降低螺旋桨的推进噪声。
