The invention discloses a satellite-borne lightweight two-dimensional pointing mechanism main frame and a two-dimensional pointing mechanism, and relates to the field of space pointing mechanisms, the satellite-borne lightweight two-dimensional pointing mechanism main frame comprises a base, a fixed joint, a first rotating frame, a second rotating frame, a first driving source, a second driving source and a feed net assembly; the fixed joint comprises a fixed plate and a fixed lug plate; the first rotating frame comprises an upper lug plate, a lower lug plate and a first bottom plate; the second rotating frame comprises a connecting lug plate and a second bottom plate; the connecting lug plate is rotationally connected to the upper lug plate, and the second bottom plate is fixed to the connecting lug plate; the first driving source is fixed to the fixed lug plate and located at the position, deviating from the first installation space, of the lower lug plate. The second driving source is fixed to the upper lug plate and located at the position, deviating from the second installation space, of the second lug plate. The feed network assembly is arranged in the first installation space and the second installation space. The two-dimensional pointing mechanism has the advantages that the problems that the mass of the two-dimensional pointing mechanism is too large, unfolding and folding are small, and a large number of whole-satellite resources are consumed are solved.

    本发明公开提供一种星载轻量化的二维指向机构主框架和二维指向机构,涉及空间指向机构领域,包括底座、固定关节、第一旋转框架、第二旋转框架、第一驱动源、第二驱动源、馈网组件;固定关节包括固定板和固定耳板;第一旋转框架包括上耳板、下耳板和第一底板;第二旋转框架包括连接耳板和第二底板;连接耳板转动连接于上耳板,第二底板固定于连接耳板;第一驱动源固定于固定耳板上且位于下耳板背离第一安装空间处;第二驱动源固定于上耳板上且位于第二耳板背离第二安装空间处;馈网组件设置于第一安装空间和第二安装空间内。本申请具有改善二维指向机构质量过大、展开收拢比较小,以及耗费大量整星资源的效果。
