Abstract

The technology of this application relates to a foldable mobile terminal. The foldable mobile terminal includes a rotating shaft mechanism, two housings, and a flexible display. The flexible display is embedded into the two housings and covers the rotating shaft mechanism. The rotating shaft mechanism has a main shaft and two rotation parts, and the rotation part rotates with the housing on a corresponding side. The flexible display is fixed to the two housings and the two rotation parts. In this way, in a folding or unfolding process of the foldable mobile terminal, relative sliding of the flexible display relative to the two housings and the rotation parts can be avoided, thereby reducing a risk of damaging the flexible display. In addition, a part of the flexible display that is opposite to the main shaft can be bent freely.

First claim

What is claimed is:

1 . A foldable mobile terminal, comprising:
a rotating shaft mechanism; two housings; and a flexible display, wherein
the two housings are respectively disposed on two sides of the rotating shaft mechanism, and the flexible display is embedded into the two housings and covers the rotating shaft mechanism,
the rotating shaft mechanism comprises a main shaft and two rotation parts respectively disposed on two sides of the main shaft, and by rotating around the main shaft, the two rotation parts are configured to form an accommodating space for accommodating the flexible display,
a housing, of the two housings, has an accommodating slot on a side close to the rotating shaft mechanism, the two rotation parts are respectively accommodated in the accommodating slots of the two housings, and the housing is configured to rotate around the main shaft to drive a rotation part of the two rotation parts on a same side to rotate,
the flexible display is fixed to the two housings and the two rotation parts, and a part of the flexible display that is opposite to the main shaft is bent freely with rotation of the housing, and
each rotation part of the two rotation parts comprise:
a connection part; and
a support plate, wherein
one end of the connection part is rotatably connected to the main shaft, and the other end thereof is fixed to the housing disposed on a same side, and
the support plate is disposed on a side of the connection part that is close to the flexible display, and the flexible display is fixedly connected to the support plate, wherein

a first are structure is disposed on the support plate, a second are structure is disposed on the housing on a same side, and the first are structure is rotatably connected to the second are structure, and
the first are structure is an are plate-like structure, and the second are structure is a solid columnar structure with an are surface, or the second are structure is an are plate-like structure, and the first are structure is a solid columnar structure with an are surface.

2 . The mobile terminal according to claim 1 , wherein a support part is disposed in the accommodating slot, and the connection part is fixedly connected to the support part.

3 . The mobile terminal according to claim 1 , wherein
the first arc structure and the support plate are integrally formed, or the first arc structure is an independent structural member disposed on the support plate.

4 . The mobile terminal according to claim 1 , wherein
the second arc structure and the housing are integrally formed, or the second arc structure is an independent structural member disposed in the housing.

5 . The mobile terminal according to claim 1 , wherein one end of the support plate, close to the main shaft, is connected to the main shaft in a lap joint manner.

6 . The mobile terminal according to claim 1 , wherein the rotation part further comprises a support plate slot disposed on the support plate, the rotating shaft mechanism further comprises a driving structure inserted into the support plate slot, and the driving structure slides along the support plate slot to drive the support plate to rotate around the housing.

7 . The mobile terminal according to claim 1 , wherein
the housing comprises a front housing and a rear housing disposed in an overlapping manner, the flexible display is fixedly connected to the front housing, and the accommodating slot is formed between an end portion of the front housing that is close to the rotating shaft mechanism and the rear housing.

8 . The mobile terminal according to claim 1 , further comprising:
a protection part, wherein
the protection part is disposed on a side of the mobile terminal facing away from the flexible display, and
the protection part is attached to the rotating shaft mechanism.

9 . The mobile terminal according to claim 3 , wherein
the second arc structure and the housing are integrally formed, or the second arc structure is an independent structural member disposed in the housing.

10 . The mobile terminal according to claim 1 , wherein an end of the support plate close to the main shaft connects to the main shaft in a lap joint manner so that the main shaft can support the support plate.

11 . The mobile terminal according to claim 1 , wherein the support plate rotates relative to the housing, and the support plate slides on the main shaft thereby avoiding collapsing the support plate at the main shaft.

12 . A mobile terminal, comprising:
a rotating shaft mechanism; first and second housings; and a flexible display, wherein
the first and second housings are respectively disposed on two sides of the rotating shaft mechanism, and the flexible display is embedded into the first and second housings and covers the rotating shaft mechanism,
the rotating shaft mechanism comprises a main shaft and two rotation parts respectively disposed on two sides of the main shaft,
a housing, of the first and second housings, has an accommodating slot on a side close to the rotating shaft mechanism, the two rotation parts are respectively accommodated in the accommodating slots of the first and second housings,
the flexible display is fixed to the first and second housings and the two rotation parts, and a part of the flexible display that is opposite to the main shaft is bent freely with rotation of the housing, and
each rotation part of the two rotation parts comprise:
a connection part; and
a support plate, wherein
one end of the connection part is rotatably connected to the main shaft, and the other end thereof is fixed to the housing disposed on a same side, and
the support plate is disposed on a side of the connection part that is close to the flexible display, and the flexible display is fixedly connected to the support plate, wherein

a first arc structure is disposed on the support plate, a second arc structure is disposed on the housing on a same side, and the first are structure is rotatably connected to the second arc structure, and
the first are structure is an are plate-like structure, and the second are structure is a solid columnar structure with an arc surface, or the second are structure is an arc plate-like structure, and the first are structure is a solid columnar structure with an arc surface.
