Abstract
The utility model discloses an internal folding retractable roof structure which comprises an internal folding link mechanism and an external annular link mechanism. N diamond four-rod link mechanisms are connected end to end through two nodes on diagonal lines to form the internal folding link mechanism. The external annular link mechanism comprises N-regular polygon rods which are connected end to end and formed by n straight rods. Each of the straight rods is provided with a link mechanism unit, the link mechanism unit is composed of an internal parallelogram mechanism and an external parallelogram mechanism, and two ends of each of the n straight rods are fixedly connected with a bearing. Single degree of freedom annular link mechanisms on the N-regular polygon rods increase stiffness of the structure of a connection position between the bearing and the N-regular polygon rods and overcome the shortcomings that a traditional folding grid structure is poor in mechanical performance and stiffness. Meanwhile, single degree of freedom performance of the external annular link mechanism reduces the number of drive devices, and the internal folding link mechanism which is formed by connection of the diamond four-rod link mechanisms end to end is adopted inside the internal folding retractable roof structure so as to enlarge opening range of a roof.
