Rotating shaft mechanism and foldable electronic equipment

Abstract

The invention relates to electronic equipment and a rotating shaft mechanism thereof. The electronic equipment comprises a first shell, a second shell and a foldable screen. The rotating shaft mechanism comprises a base and a rotating assembly which are rotatably connected with each other. The rotating assembly comprises a support, a linkage piece and a guide piece. The support and the base are arranged at an interval, and the linkage piece is arranged between the base and the support. The linkage piece comprises a body and a driving part arranged on the body; one end of the body is rotatably connected to the base, and the other end of the body is slidably connected to the support. The guide piece is rotatably connected to the bracket; the guiding piece is provided with a sliding groove, and the driving part is at least partially contained in the sliding groove. When the base and the rotating assembly rotate relatively, the driving part slides in the sliding groove so as to drive the guiding piece to rotate relative to the support. According to the rotating shaft mechanism, the foldable screen can be protected when the foldable screen is folded, and damage caused by irregular deformation of folding of the foldable screen is avoided.

Description

technical field [0001] The present application relates to the field of electronic equipment, in particular to a hinge mechanism and foldable electronic equipment. Background technique [0002] Currently, a foldable electronic device, such as a foldable mobile phone, realizes the miniaturization of the mobile phone by folding the display screen of the mobile phone in half, so as to be convenient for the user to carry. A traditional folding mobile phone generally includes a first shell and a second shell pivotally connected to each other, and a flexible display screen covering one side of the first shell and the second shell. The first casing and the second casing can be turned over to form a stacked shape, and at this time, the flexible display screen is in a half-folded state. However, since the edges of the flexible display screen are usually fixedly connected to the first housing and the second housing, when the flexible display screen is folded in half, its roughly centr...

Problems solved by technology

However, since the edges of the flexible display screen are usually fixedly connected to the first housing and the second housing, when the flexible display screen is folded in half, its roughly central area will be subjected to pressure from its edge and the first housing and the second housing. The extrusion force of the electronic device and the support force of the internal components of the electronic device cause arching deformation. The direction of the arching deformation is opposite to the folding direction, resulting in creases or even delamination of the flexible display screen, which easily leads to failure of the flexible display screen. , reducing the life of the flexible display
