SPLIT-TYPE COMPOSITE LIGHTWEIGHT CONNECTING ROD ASSEMBLY AND MANUFACTURING METHOD THEREFOR

WIPO Patent Application WO/2021/052038

A1

Disclosed are a split-type composite lightweight connecting rod assembly and a manufacturing method therefor. The split-type composite lightweight connecting rod assembly comprises a spherical hinge (30), a rod body (20), and a joint (10), wherein the joint is made of a composite material, the rod body is made of a metal or continuous fiber reinforced composite material, the rod body is connected to the joint, the spherical hinge is mounted in the joint, and the rod body and the joint are integrally injection-molded or fixedly connected, such that an end portion of the rod body is connected to the joint. According to the connecting rod, the center distance can be adjusted, the universality of a product is greatly improved, and the split structure can relatively shorten the flow distance of macromolecules, thereby avoiding the risk of inferior-quality products caused by an insufficient flow. An injection molding weld line is arranged at the end of a molding, i.e. the non-stressed position of a product, thereby effectively improving the strength of the product.
