The invention provides a four-degree-of-freedom deformation coordination bracket structure. The bracket structure comprises a spherical joint (1), two sliding plates (2) and a bracket (3), the two ends of the spherical joint (1) are of spherical structures; one end of the spherical joint 1 is sleeved and fixed on a cylinder at one end of a connected piece (5), the other end of the spherical joint 1 is connected with the two sliding plates (2), the two sliding plates are oppositely buckled on the periphery of the spherical joint (1) and are symmetrically distributed relative to the axis of the spherical joint (1), and concave spherical surfaces at two ends of each sliding plate are in sliding fit with spherical surfaces at two ends of the spherical joint (1). The middle convex structures of the sliding plates are supported on the outer surface of the middle of the spherical joint (1), the two sliding plates (2) are relatively and fixedly connected, the sliding plates (2) are slidably supported in the bracket (3), and the bracket (3) is fixedly connected with an aircraft support. The technical problem that in the prior art, an aircraft equipment installation structure cannot give consideration to installation rigidity and multi-degree-of-freedom deformation coordination is solved.
本发明提供了一种四自由度变形协调支架结构,该支架结构包括球形接头(1)、2个滑板(2)和支架(3);球型接头(1)的两端为球形结构;球形接头1的一端套装并固定在被连接件(5)的一端柱体上,球型接头1的另一端与2个滑板(2)连接,2个滑板对扣在球型接头(1)外周上,且2个滑板相对球型接头(1)的轴线对称分布,滑板两端内凹球面与球型接头(1)的两端球面滑动配合,滑板中部外凸结构支撑在球型接头(1)中部外表面上,2个滑板(2)相对固定连接,滑板(2)滑动支撑在支架(3)内,支架(3)与飞行器支座进行固定连接。本发明解决现有技术中飞行器设备安装结构不能兼顾安装刚度和多自由度变形协调的技术问题。
