Hinge structure

The present invention relates to a hinge structure, and more particularly to a hinge structure of an electronic device.

At present, a portable electronic device such as a notebook computer generally includes a body and a cover. The display screen is disposed on the cover body. In order to provide a better viewing angle of the display screen, the cover body is generally rotatably connected to the body by a hinge structure. .

A biaxial hinge structure includes a first bracket, a second bracket, a first pivoting assembly and two second pivoting assemblies. The second pivoting assembly is horizontally disposed at two ends of the first bracket, the first pivoting component is vertically disposed in the middle of the first bracket, and the second bracket is non-rotatably disposed on the first pivoting component. The first pivoting assembly includes a limiting spacer, the edge of the limiting spacer is formed with a limiting portion, and the first bracket forms a limited position protrusion near the first pivoting assembly. The limiting portion of the limiting spacer cooperates with the limiting protrusion of the first bracket to limit the rotation angle of the first bracket relative to the second bracket. When the above-mentioned biaxial hinge structure is applied to an electronic device, the second bracket is connected to the body, and the second pivot assemblies are respectively connected to the cover body.

However, since the above-mentioned biaxial hinge structure adopts a limiting structure in which the limiting spacer cooperates with the limiting protrusion on the first bracket, the cover body connected to the biaxial hinge structure cannot be wound around the first pivoting component. The axis realizes a 360 degree rotation, and when the cover body is rotated over 180 with respect to the first pivoting assembly, the cover body needs to be rotated back to the initial position in a direction opposite to the original rotation direction, which is inconvenient to use.

In view of the above, it is necessary to provide a hinge structure that enables the cover of an electronic device to be rotated 360 degrees about its axis.

The first pivoting assembly of the hinge structure includes a first limiting member and a second limiting member sleeved on the rotating shaft, and the second limiting member can push the first limiting member to rotate together, and the second bracket is opposite to the first bracket The rotation angle is equal to the sum of the angle of the second rotation of the second limiting member and the angle of rotation of the first limiting member in the sliding groove of the second bracket, and the first limiting member and the second limiting member are attached during use. Rotating in different planes, so the angle of rotation of the second limiting member and the angle of rotation of the first limiting member in the sliding groove of the second bracket can reach up to 360 degrees, so the second bracket can be relatively first The bracket is rotated more than 360 degrees, and after the hinge structure is applied to the electronic device, the cover connected to the second bracket can be rotated 360 degrees around the rotating shaft, which is convenient to use.
