Hinge structure and electronic device using the same

The invention relates to a hinge structure and an electronic device using the hinge structure.

Common electronic devices, such as notebook computers, flip-type mobile phones, and electronic dictionaries, generally need to connect the cover body and the main body by a hinge structure. In the process of using the notebook computer, the cover body is required to be positioned at any angle to facilitate the user's operation, which requires a certain friction between the internal components of the hinge structure.

A hinge structure on an electronic device includes a main shaft, a friction tube fixed on the main shaft, a follower sleeve sleeved on the main shaft and rotatable relative to the main shaft, and a sleeve sleeved on the element. The friction tube has a friction cone at one end. The driven member has a driven surface and a limiting groove, and the driven surface is also a tapered surface, abutting against the friction cone surface of the friction tube, and the bracket is provided with a finite position protrusion, and the limiting protrusion and the follower are The limit groove cooperates to limit the range of rotation angle of the follower relative to the bracket. The frictional force can be generated by the tapered surface between the friction tube and the driven member, so that the cover body stays at any angle. In addition, an elastic member that abuts against the driven member is further sleeved on the main shaft, and the elastic member can maintain a certain frictional force after the long-term use of the follower member and the friction tube.

The follower of the hinge structure, the friction tube and the elastic member are all sleeved on the main shaft, and the sleeve is sleeved on the above components, so the sleeve of the hinge structure usually has a large volume and an inner diameter. Accommodating the above components, and this inevitably makes the size of the entire hinge structure larger, thereby affecting the electronic device Exterior.

In view of the above circumstances, it is necessary to provide a hinge structure having a small volume and a long service life and an electronic device using the hinge structure.

A hinge structure, comprising a main shaft, a sleeve sleeved on the main shaft, an actuating member housed in the main shaft, a rotating shaft rotatably connecting the actuating member to the main shaft, and friction members at the opposite ends respectively corresponding to the actuating member and the sleeve The elastic member that the actuator abuts, the elastic member generates an elastic force for rotating the actuating member about the rotating shaft.

An electronic device includes a body, a cover body, and a hinge structure for rotatably connecting the cover body to the main body, the hinge structure including a main shaft, a sleeve sleeved on the main shaft, and an actuating member housed in the main shaft The actuating member is rotatably coupled to the rotating shaft of the main shaft, the friction member at the two ends respectively abutting against the actuating member and the sleeve, and the elastic member abutting against the actuating member, and the elastic member can generate an elastic force for rotating the actuating member about the rotating shaft.

The friction member, the elastic member and the actuating member of the hinge structure on the electronic device are all housed in the main shaft, and the sleeve can be directly designed according to the size of the main shaft, without considering the size required for accommodating other components, and reducing the hinge structure. Overall volume. Moreover, when wear occurs between the friction member and the sleeve, since the actuating member is rotatable about the rotating shaft under the elastic force of the elastic member, the friction member and the sleeve are still held against each other, thereby improving the hinge structure. Service life.
