Torsion piece type self-closing structure and double-shaft-core rotating shaft adopting same

Abstract

The invention discloses a torsion piece type self-closing structure and a double-shaft-core rotating shaft adopting the same. The torsion piece type self-closing structure comprises a first shaft core, a second shaft core, a first connecting plate, a second connecting plate and at least one torsion piece. The torsion pieces are arranged and a cut face is arranged on one shaft core, so that with the aid of matching of the cut face on the corresponding shaft core as well as closing arc faces and torsion arc faces on the torsion pieces, a self-closing function at a specific angle is achieved while rotating torsion is provided. According to the double-shaft-core rotating shaft adopting the torsion piece type self-closing structure, the occupied space of the rotating shaft can be reduced whilethe rotating torsion is provided and the self-closing function at the specific angle is achieved, so that the thinning development requirement of electronic equipment such as notebook computers can bewell met.

Description

technical field [0001] The invention relates to a double-axis core rotating shaft, in particular to a torsion plate type self-closing structure and a double-axis core rotating shaft using the same. Background technique [0002] The hinge, also known as the hinge, is a connecting element that can provide mutual rotation. It is mainly used between the rotating parts and its base. At present, it is widely used in various digital products and electronic equipment, such as notebook computers. Rotation can realize the opening and closing function between the body of the notebook computer and the display screen. [0003] In the prior art, the self-closing function of the rotating shaft is usually realized by the cooperation between the concave or convex point of the concave wheel on the shaft core of the rotating shaft and the convex or concave point on the cam. According to the development requirements of thinness, the space occupied by the rotating shaft connecting the substrate...

[0003] In the prior art, the self-closing function of the rotating shaft is usually realized by the cooperation between the concave or convex point of the concave wheel on the shaft core of the rotating shaft and the convex or concave point on the cam. According to the development requirements of thinness, the space occupied by the rotating shaft connecting the substrate and the display screen is getting smaller and smaller, and the self-closing structure in the form of cam and concave wheel often needs to occupy a large space, which can no longer meet the development needs of thin electronic equipment.
