AI Technical Summary
Technical Problem
Existing hinge mechanisms limit the lightweight design of foldable electronic devices due to the large mass of the base assembly and the central support plate.
Method used
By replacing the central support plate with a support rod, and through structural designs such as a trajectory rod, a rotating component, and a synchronization rod, smooth support and synchronous movement of the screen are achieved, reducing the overall mass of the hinge mechanism.
Benefits of technology
It effectively reduces the overall weight of the hinge mechanism, which is conducive to the lightweight design of foldable devices and improves the flatness of the screen and ease of use.

Abstract
The present disclosure is a kind of hinge mechanism and foldable device, relating to electronic device technical field.The hinge mechanism includes base assembly, multiple trajectory rods, two rotating assemblies and support rods, part of the multiple trajectory rods is located on one side of the base assembly, another part is located on the other side of the base assembly, and the multiple trajectory rods are all rotationally connected with the base assembly, the two rotating assemblies are respectively located on both sides of the base assembly, and are rotationally connected with the base assembly and the corresponding trajectory rod, and each support rod is connected with the trajectory rod located on the same side of the base assembly.The trajectory rod can drive the support rod to move together, and when the hinge mechanism is in the unfolded state, the support rod can effectively support the screen, and the support rod is used instead of the heavy middle support plate in the related art, which can effectively reduce the overall quality of the hinge mechanism, and is conducive to the lightweight design pursuit of the foldable device.
