Description

In order to support the weight of the upper cover and the base and reduce the force required for opening and closing, the hinge device also generally comprises a torsion component for providing the torsion required for opening and closing.

When the hinge device is assembled, the two coaxially pivoted bearing frames are respectively connected between the upper cover and a convex part of the base, namely, the connection position of the upper cover and the base is fixed and cannot be changed along with the lifting angle of the upper cover. For example, after the upper cover of the electronic product rotates and opens relative to the base through the hinge, the upper cover contacts the protruding portion of the base to form interference, so that the upper cover cannot be opened to a preset maximum opening angle. Accordingly, a solution for those skilled in the art is to enlarge the structural space (gap) between the upper cover and the protruding portion of the base, which is clearly a relative condition for the user that the display screen is pulled far away in use, and at the same time, the structural space is visually defective, which is detrimental to the aesthetic appearance of the electronic product.
