Description

Folding device and electronic equipment

Technical field

The present invention relates to the field of flexible member support, and in particular to a folding device supporting a flexible member and an electronic device provided with the folding device.

Background technique

With the development of display devices, a flexible ultra-thin flexible screen has emerged. Compared with traditional display devices, flexible screens have advantages such as foldability and flexibility, and are widely favored by consumers. The existing flat support structure obviously cannot meet the demand, so the industry has developed a support structure that can adapt to the bending demand of the flexible screen. The existing support structure usually connects a slidable sliding component to the hinge for sliding compensation. However, the existing sliding parts are generally arranged on the outside of the hinge as a separate external component, which needs to occupy a part of the internal space of the whole machine, which causes the internal space of the whole machine to be cramped and is not conducive to the arrangement of other electronic devices.

Application content

The present application provides a folding device that is not easily damaged by a flexible member, and an electronic device provided with the folding device.

A folding device provided by the present application includes a hinge and a support. The hinge includes a folding component and two connecting hinges arranged on opposite sides of the folding component. The two connecting hinges include a first connecting hinge. And a second connecting hinge, the first connecting hinge and the second connecting hinge are respectively slidable relative to the folding assembly, and the support is connected to the first connecting hinge and the second connecting hinge .

The present application also provides an electronic device, including a flexible member, a housing, and a folding device. The housing includes a first frame and a second frame. The folding device is disposed on the first frame and the second frame. Between the two frames, the flexible member is arranged on the housing and the folding device, and the flexible member is bent or flattened along with the folding device.

The folding device of the electronic device of the present application includes a hinge and a support. The hinge includes a folding component and two connecting hinges arranged on opposite sides of the folding component. The two connecting hinges can be opposite to the folding component. Sliding, the support member is connected to the two connecting hinges; during the bending or flattening process of the bending mechanism, the length of the support member in the direction perpendicular to the bending axis of the bending mechanism does not change, The connecting joint of the hinge itself can be directly used as a sliding compensation component, without additional external sliding components, which can effectively save occupied space and facilitate the arrangement of other electronic devices.
