Abstract

An electronic device, including a first device body, a second device body, a rotating mechanism, and a flexible display screen, is disclosed. The flexible display screen comprises a first display screen, a second display screen, and a third display screen. The first device body is rotationally connected to the second device body through a rotating mechanism. The first display screen is connected to the second display screen through the third display screen. The first device body is connected to the first display screen, and the second device body is connected to the second display screen. The rotating mechanism includes a rotating shaft, a transmission apparatus, and a moving component equipped with a first transmission tooth that meshes with the transmission apparatus, the rotating shaft is connected to the moving component through the transmission apparatus, and the first device body or the second device body is connected to the moving component.

Claims (43)

1 . An electronic device, comprising:

a first device body;

a second device body;

a rotating mechanism; and

a flexible display screen, wherein:

the flexible display screen comprises:

a first display screen;

a second display screen; and

a third display screen;

the first device body is rotationally connected to the second device body through the rotating mechanism;

the first display screen is connected to the second display screen through the third display screen;

the first device body is connected to the first display screen, and the second device body is connected to the second display screen;

the rotating mechanism comprises:

a rotating shaft;

a transmission apparatus; and

a moving component, wherein the moving component is equipped with a first transmission tooth that meshes with the transmission apparatus, the rotating shaft is connected to the moving component through the transmission apparatus, and at least one of the first device body and the second device body is connected to the moving component; and

the first device body and the second device body is configured to rotate relative to each other, so that the electronic device switches between a folded state and an unfolded state, and wherein

when the electronic device switches from the folded state to the unfolded state, the rotating shaft is configured to drive the moving component away from the rotating shaft through the transmission apparatus; or

when the electronic device switches from the unfolded state to the folded state, the rotating shaft is configured to drive, through the transmission apparatus, the moving component to approach the rotating shaft.

2 . The electronic device according to claim 1 , wherein the rotating mechanism further comprises a support plate,

wherein when a number of rotating shafts is at least two, the rotating mechanism further comprises a first shaft and a second shaft,

wherein the support plate comprises a first gear portion connected to the first shaft, the support plate comprises a second gear portion connected to the second shaft, and

wherein the first gear portion is sleeved on the first shaft, the second gear portion is sleeved on the second shaft, and the first gear portion meshes with the second gear portion.

3 . The electronic device according to claim 2 , wherein the rotating mechanism further comprises a rotating shaft bracket,

wherein the rotating shaft bracket is equipped with a first hole and a second hole,

wherein one end of the first shaft passes through the first hole, and one end of the second shaft passes through the second hole, and

wherein the rotating shaft bracket is equipped with an arc-shaped support surface, and when the electronic device is in the folded state, the arc-shaped support surface faces the third display screen.

4 . The electronic device according to claim 1 , wherein the rotating mechanism further comprises a support plate,

wherein the support plate is connected to the rotating shaft,

wherein the transmission apparatus comprises:

a support shaft;

a second gear; and

a synchronous belt,

wherein a first end of the support shaft is connected to the support plate, the first gear is sleeved on the rotating shaft, the second gear is sleeved on the support shaft, the first gear is transmission connected to the second gear through the synchronous belt, and the synchronous belt meshes with the moving component.

5 . The electronic device according to claim 4 , wherein an inner surface of the synchronous belt is equipped with a second transmission tooth, the moving component is equipped with a first surface facing the inner surface, the first surface is equipped with the first transmission tooth, and the second transmission tooth meshes with the first transmission tooth.

6 . The electronic device according to claim 4 , wherein the rotating mechanism further comprises a connecting rod, wherein one end of the connecting rod is sleeved on the rotating shaft, and the other end of the connecting rod is sleeved on a second end of the support shaft.

7 . The electronic device according to claim 6 , wherein the synchronous belt is located between the support plate and the connecting rod.

8 . The electronic device according to claim 6 , wherein the synchronous belt and the connecting rod are both located between two ends of the moving component, and a surface of the connecting rod facing the moving component is equipped with an avoidance recess.

9 . The electronic device according to claim 1 , wherein the rotating mechanism further comprises a support plate, wherein the support plate is connected to the rotating shaft, the first device body is equipped with a first guide part, and one end of the support plate away from the rotating shaft slidably fits with the first guide part.

10 . The electronic device according to claim 1 , wherein when the electronic device is in the folded state, the first device body and the second device body are both located between the first display screen and the second display screen.

11 . The electronic device according to claim 1 , wherein the rotating mechanism further comprises a damper, wherein the damper is equipped in the rotating shaft.

12 . The electronic device according to claim 1 , wherein the first device body is equipped with a second guide part, the rotating mechanism further comprises a guide rod, wherein one end of the guide rod is sleeved on the rotating shaft, and the other end of the guide rod slidably fits with the second guide part.
