Abstract

The invention provides a hinge structure. The hinge structure comprises a rotating shaft, a first bracket, an elastic component and a locking member, wherein the rotating shaft comprises a shaft lever; the elastic component and the locking member are sleeved on the shaft lever; the first bracket is sleeved on the locking member; the locking member is provided with a locking part; the shaft lever is provided with a limiting part; and the locking part of the locking member can move in the limiting part so as to realize self-lock of the hinge structure. The hinge structure has the advantages of low manufacturing cost and small occupied space.

Description

technical field [0001] The invention relates to a hinge structure, in particular to a hinge structure with self-locking function. Background technique [0002] With the gradual improvement of consumer requirements on the appearance of electronic devices and the continuous simplification of electronic device structures, it has become a hinge design trend to add self-locking elements in the hinge structure of electronic devices to replace common snap-fit ​​devices. [0003] A hinge structure includes a rotating shaft, a bracket that is sequentially sleeved on the rotating shaft, a friction plate, a coupling member, a cam assembly, and an elastic member. Each element is locked on the rotating shaft through a fastener, and the elastic member is compressed. The cam assembly includes a fixed part and a driven part, the fixed part is provided with several wedge-shaped blocks, and the driven part is provided with several wedge-shaped grooves matched with the wedge-shaped blocks. Wh...
