Description

Hinge structure

The present invention relates to a hinge structure, and in particular to a hinge structure used in electronic devices.

Existing notebook computers use a hinge module to pivotally connect the display body and the logic body, so that the display body and the logic body can be unfolded or folded relative to each other to switch to a working mode or a storage mode. However, most of the existing hinge modules use a single axis, so that the expansion angle of the display body relative to the logic body and the distance relative to the user cannot be adjusted. This results in limitations in the use of notebook computers, and users need to combine external parts to adjust to the desired viewing angle and distance.

The present invention provides a hinge structure suitable for combination with an electronic device. During the process of unfolding the electronic device, the screen body moves relative to the logic body through the hinge structure.

The hinge structure of the present invention includes a first fixed frame and a second fixed frame, a transmission module, a first rotating shaft and a base. The first fixed frame and the second fixed frame The fixed frames are arranged at intervals from each other. The transmission module is disposed between the first fixed frame and the second fixed frame and has a sector gear. The first rotating shaft has a first turning part and a first mounting part. The first steering part is rotatably installed on the first fixed frame, the second fixed frame and the transmission module. The first mounting portion protrudes outside the first fixing frame. The transmission module is disposed between the first fixed frame and the second fixed frame and has a sector gear. The base has a linearly extending rack that meshes with the sector gear. The first fixed frame and the second fixed frame are adapted to pivot around the first rotating shaft and drive the sector gear of the transmission module to move along the rack.

Based on the above, the hinge structure of the present invention is suitable for combining with electronic devices. The first fixing bracket and the second fixing bracket are used to connect the screen body and the first carrier plate is used to connect the logic body. When the screen body is unfolded relative to the logic body, the The first fixed frame and the second fixed frame are driven to rotate relative to the first rotating shaft, thereby driving the sector gear of the transmission module to move along the rack of the base, causing the linear distance of the screen body relative to the user to change.
