HINGE STRUCTURE AND FOLDABLE DEVICE

The present application provides a hinge structure and a foldable device. The hinge structure comprises: a first bearing support, wherein a first shaft sleeve is arranged on the first bearing support, and a boss structure is arranged on an end face of the first shaft sleeve; a second bearing support, wherein a second shaft sleeve is arranged on the second bearing support, and a groove structure is arranged on an end face of the second shaft sleeve; a shaft core, wherein the first shaft sleeve and the second shaft sleeve are sleeved in parallel on the shaft core; and an elastic member, used for enabling the boss structure and the groove structure to be mutually engaged when the first bearing support and the second bearing support rotate relative to each other to a preset angle so as to lock a rotating angle. The present application realizes the angle locking of a hinge by designing two shaft sleeves on two different bearing supports into a concave-convex wheel mechanism, thereby reducing the production impleme
