The invention discloses a distributed driving variant nose cone containing a flexible hinge. The distributed driving variant nose cone comprises a nose cone shell and a spiral branch chain assembly. Wherein the nose cone shell comprises a plurality of sub-shells which are coaxially and sequentially arranged from front to back; a plurality of spiral branch chain assemblies are arranged between every two adjacent sub-shells and distributed in the circumferential direction of the nose cone shell. Each spiral branched chain assembly comprises a flexible hinge base, a nut base and a screw rod, the flexible hinge base is arranged on the inner side of the front end of the rear sub-shell of every two adjacent sub-shells, the flexible hinge base can be bent and rotate, the nut base is arranged on the inner side of the rear end of the front sub-shell of every two adjacent sub-shells, and the screw rod can be screwed on the nut base. The rear end of the screw rod is in spherical hinge connection with the flexible hinge base, the threaded section of the screw rod rotatably penetrates through the nut base in a matched mode, and the screw rod is parallel to the central axis of the nose cone shell when the flexible hinge base does not bend and rotate. The variant nose cone disclosed by the invention can be subjected to telescopic deformation and bending deformation, and is high in movement stability.
本发明公开了一种含柔性铰链的分布式驱动变体头锥,包括头锥壳体和螺旋支链组件。其中,头锥壳体包括多个自前向后同轴依次设置的子壳体;两两相邻的子壳体之间均设有多个螺旋支链组件,多个螺旋支链组件沿头锥壳体的周向分布;每个螺旋支链组件包括柔性铰链基座、螺母基座和螺杆,柔性铰链基座设置在两两相邻的子壳体中的后一个子壳体的前端内侧,柔性铰链基座可弯曲转动,螺母基座设置在两两相邻的子壳体中的前一个子壳体的后端内侧,螺杆的后端与柔性铰链基座球铰连接,螺杆的螺纹段适配可转动地穿过螺母基座,螺杆在柔性铰链基座不发生弯曲转动时与头锥壳体的中心轴线平行。本发明的变体头锥可以发生伸缩变形和弯曲变形,且运动稳定性高。
