AI Technical Summary

Technical Problem

In existing foldable equipment, the risk of damage to the flexible screen fixedly connected to the surface of the three structural parts is high, and it is difficult to meet the needs of a three-fold or above structure.

Method used

A foldable device is designed, and the housing assembly includes a first structural member, a second structural member, a third structural member, a first rotary shaft mechanism and a second rotary shaft mechanism. The flexible screen consists of a support layer and a cover layer, which is fixedly connected to the second structural member and the first area, and the cover layer is fixedly connected to the third structural member and the second area. When the equipment is folded, the staggered directions of the support layer and the cover plate layer are coordinated to avoid squeezing or pulling caused by staggered stacking.

Benefits of technology

It effectively reduces the risk of flexible screen damage, improves the stability and service life of foldable equipment with three fold and above structures, and at the same time, it has less restrictions on the folding form and method.

Abstract

The embodiment of the invention provides foldable equipment, and relates to the technical field of terminal products. The foldable device comprises a first structural member, a second structural member, a third structural member, a first rotating shaft mechanism, a second rotating shaft mechanism and a flexible screen. One end of the first structural member is rotationally connected with the second structural member through a first rotating shaft mechanism, and the other end of the first structural member is rotationally connected with the third structural member through a second rotating shaft mechanism. The flexible screen comprises a supporting layer and a cover plate layer, the supporting layer is fixedly connected with one part of the first structural part and the second structural part, the cover plate layer is fixedly connected with the other part of the first structural part and the third structural part, or the second structural part and the third structural part are folded towards different sides of the first structural part respectively. Thus, in the folding process of the foldable equipment, the supporting layer and the cover plate layer are not prone to being extruded or pulled due to dislocation and superposition, and the risk that the flexible screen is damaged can be reduced.
