Description
Technical Field
The present invention relates to a hinge device, and more particularly to a hinge device with a translation function capable of moving when a display of a foldable electronic device is opened.
Background
The conventional foldable electronic device, such as the upper cover (or the display) and the base of a notebook computer, is mainly pivoted by connecting the side edge of the upper cover and the base respectively through a single-spindle hinge or a dual-spindle hinge, so that the upper cover can be turned over and lifted or closed relative to the base. When the hinge is assembled, two bearing frames which are coaxially pivoted are respectively connected between the upper cover and a bulge part of the base, so that the connecting position of the upper cover and the base is fixed and cannot be changed along with the lifting angle of the upper cover.
When the upper cover rotates relative to the base through the hinge and is opened to a certain angle, the upper cover touches the bulge part of the base to form interference, and the upper cover cannot be opened to a preset maximum opening angle. In order to avoid interference, the design of the upper cover must be designed to include structures, such as: the gap between the upper cover and the bulge of the base is enlarged. This causes the display to be pulled away when the electronic device is used, and the gap between the two structures may cause a visual defect, which is not good for the aesthetic appearance of the electronic device.

The rotating shaft module comprises a first rotating shaft, a second rotating shaft, a connecting piece, a switching piece and a transmission coupling piece. The first rotating shaft is assembled on the first machine body and is provided with a first limiting part. The second rotating shaft is movably and rotatably assembled on the second body, and is fixedly connected to the connecting piece and provided with a second limiting part. The first rotating shaft is rotatably assembled on the connecting piece, the switching piece is movably arranged in the connecting piece in a penetrating mode, and the first limiting part and the second limiting part are located at two opposite ends of a moving path of the switching piece, so that the switching piece interferes with the first limiting part or the second limiting part. The transmission coupling part is arranged on the second rotating shaft and the second machine body respectively, and the second rotating shaft is converted into linear motion of the second machine body relative to the second rotating shaft through the transmission coupling part relative to the rotary motion of the second machine body. Therefore, after the rotating shaft module (pivot device) is installed, the structural distance between the upper cover and the boss of the base is effectively reduced, and meanwhile, when the upper cover is lifted, the interference phenomenon with the boss cannot be generated. The above-mentioned patent is complex in overall structure, and especially in the design of the linkage structure and the rotation stop of each component, it not only increases the production cost, but also is not favorable for assembly and maintenance.
