Embodiment Construction

[0037] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0038] The scissor hinge driven by the extension spring in the present invention can expand the dome structure, which includes several rods 3 with identical structural shapes. The middle part of the rod 3 is provided with a low platform lower than the surface of the rod 3 along its length direction, and a hinge hole 4 is arranged in the middle of the low platform. The scissor hinge structure is equally divided to realize the coplanarity of the two rods and the maximum rotation angle during the hinge rotation process; the six scissor hinge structures are arranged in sequence and are connected by twelve identical node parts 2 to form a ring unit. In the hinge structure, the outer node part 2 is connected with the inner node part 2 on the same side through a tension spring 17; the expandable dome structure includes at least three ring units, and th...

Abstract

The invention relates to the technical field of architectural engineering and aerospace, and aims to provide an unfoldable dome structure of a tension spring-driven shear hinge. The structure comprises at least three annular units, wherein rod members and node parts are connected in a hinged manner; low table parts of every two rod members are relatively assembled by screws to form shear hinge structures; six shear hinge structures are arranged in sequence, and are connected by twelve node parts to form one annular unit; the node parts at the external in one shear hinge structure are connected with the node parts at the same side at the internal through tension springs; the gathering state size of the structure depends on the section sizes and the length sizes of the rod members, and the spreading state size of the structure depends on the length sizes of the rod members, so that the gathering rate is higher, the small space requirement in rocket launching and the large space requirement in aerospace are satisfied, and the assembly, construction and transportation convenience requirements and the building space coverage requirement are satisfied; and the structure is convenient to be carried in the folding state, and is wide in functions in the spreading state. The structure is wide in application range, is gradient, and is higher in economic effect.

Description

technical field [0001] The invention relates to the fields of construction engineering and aerospace technology, in particular to a spring-driven scissor hinge expandable dome structure suitable for use as a portable tent frame or an expandable antenna frame. Background technique [0002] In the field of construction engineering, the idea of ​​prefabricated buildings has attracted more and more attention. Reducing construction costs and speeding up construction is the development trend of construction; portable and convenient products are gradually becoming popular in people's lives. The traditional deployable structure has been applied in the construction field due to its advantages of convenient construction, but most of them are limited to one-dimensional line deployment and two-dimensional surface deployment. The deployment process cannot release three-dimensional space, so the application field is limited. [0003] In the field of aerospace technology, the space deploy...
