The invention provides an aircraft variant nose cone based on diamond mechanism driving, which comprises three conical nose cone shells arranged in sequence, the third nose cone shell is a cone head, the first and third nose cone shells are respectively provided with a group of hinge bases, the first and second nose cone shells are respectively provided with a group of locking hinge bases, and the locking hinge bases are respectively provided with a group of locking hinge bases. The second-section head cone shell is connected with two groups of hinge bases, and the second-section head cone shell and the third-section head cone shell are respectively provided with a group of locking hinge bases; the locking mechanism comprises a locking rod set, and the locking rod set is connected to the locking hinge base and the locking hinge base. The sections are connected through the rhombus mechanism branch chains, the spherical hinge mechanism branch chains and the locking rod sets, the rhombus mechanism branch chains are driven by the driving assembly, and the nose cone shell is driven to deform by changing the lengths of the rhombus mechanism branch chains. The invention can realize telescoping and bending deformation, can be used for a morphing aircraft to improve the adaptability and flexibility of the aircraft, and has the advantages of stable movement, large deformation, simple driving, light overall weight and the like.

    本发明提供了一种基于菱形机构驱动的飞行器变体头锥,包括依次设置的三节锥形头锥外壳,第三节头锥外壳为锥头,第一节和第三节头锥外壳各安装一组铰链基座,第一节和第二节头锥外壳各安装一组锁定铰链底座,第二节头锥外壳连接两组铰链基座,第二节和第三节头锥外壳各安装一组锁定铰链基;锁定机构包括锁定杆组,锁定杆组连接在锁定铰链底座和锁定铰链基座上;节与节之间通过菱形机构支链、球铰机构支链和锁定杆组连接,菱形机构支链由驱动组件驱动,通过改变菱形机构支链的长度进而驱动头锥外壳变形。本发明能够实现伸缩和弯曲变形,可用于变体飞行器以提高飞行器的适应性和灵活性,具有运动稳定、变形量大、驱动简单、整体质量轻等优点。
