Abstract

An electronic device includes a flexible screen, a first housing, a second housing, a stylus, and a transmission structure. The flexible screen is connected to the first housing and the second housing, the transmission structure is arranged on the first housing, and the stylus is connected to the transmission structure; in a case that the flexible screen is driven to fold by the first housing and the second housing, the transmission structure drives the stylus to approach the flexible screen, to accommodate the stylus in a gap formed after the flexible screen is folded; and in a case that the flexible screen is driven to unfold by the first housing and the second housing, the transmission structure drives the stylus to move away from the flexible screen, to cause the stylus and the flexible screen to form a preset included angle.

Claims (35)

1 . An electronic device, comprising: a flexible screen, a first housing, a second housing, a stylus, and a transmission structure, wherein

the first housing is movably connected to the second housing, the flexible screen is connected to the first housing and the second housing, the transmission structure is arranged on the first housing, and the stylus is connected to the transmission structure;

in a case that the flexible screen is driven to fold by the first housing and the second housing, the first housing drives the transmission structure to move, and the transmission structure drives the stylus to approach the flexible screen, to accommodate the stylus in a gap formed after the flexible screen is folded; and

in a case that the flexible screen is driven to unfold by the first housing and the second housing, the first housing drives the transmission structure to move, and the transmission structure drives the stylus to move away from the flexible screen, to cause the stylus and the flexible screen to form a preset included angle.

2 . The electronic device according to claim 1 , wherein the transmission structure comprises a transmission rod and a transmission gear assembly;

the transmission gear assembly is rotatably connected to the first housing, a first transmission insection is provided on the transmission rod, the transmission gear assembly is engaged with the first transmission insection, and the transmission rod is connected to the stylus;

in a case that the flexible screen is driven to fold by the first housing and the second housing, the transmission gear assembly rotates along a first direction to cause the transmission rod to rotate along a first rotation direction, and the transmission rod drives the stylus to approach the flexible screen; and

in a case that the flexible screen is driven to unfold by the first housing and the second housing, the transmission gear assembly rotates along a second direction to cause the transmission rod to rotate along a second rotation direction, and the transmission rod drives the stylus to move away from the flexible screen, wherein

the first direction and the second direction are reverse, and the first rotation direction and the second rotation direction are reverse.

3 . The electronic device according to claim 2 , wherein the first housing is connected to the second housing through a hinge component;

the hinge component is connected to the transmission gear assembly;

in a case that the flexible screen is driven to fold by the first housing and the second housing, the hinge component drives the transmission gear assembly to rotate along the first direction; and

in a case that the flexible screen is driven to unfold by the first housing and the second housing, the hinge component drives the transmission gear assembly to rotate along the second direction.

4 . The electronic device according to claim 3 , wherein the hinge component is connected to a sliding block, a second transmission insection is provided on the second sliding block, and the second transmission insection is engaged with the transmission gear assembly;

in a case that the flexible screen is driven to fold by the first housing and the second housing, the hinge component drives the sliding block to slide along a first sliding direction, to cause the sliding block to drive the transmission gear assembly to rotate along the first direction; and

in a case that the flexible screen is driven to unfold by the first housing and the second housing, the hinge component drives the sliding block to slide along a second sliding direction, to cause the sliding block to drive the transmission gear assembly to rotate along the second direction, wherein

the first sliding direction and the second sliding direction are reverse.

5 . The electronic device according to claim 2 , wherein a driving assembly is arranged in the first housing;

the driving assembly is connected to the transmission gear assembly;

in a case that the flexible screen is driven to fold by the first housing and the second housing, the driving assembly drives the transmission gear assembly to rotate along the first direction; and

in a case that the flexible screen is driven to unfold by the first housing and the second housing, the driving assembly drives the transmission gear assembly to rotate along the second direction.

6 . The electronic device according to claim 5 , wherein the driving assembly comprises a driving member and a driving rod;

the driving member is connected to the driving rod, a driving insection is provided on the driving rod, and the driving insection is engaged with the transmission gear assembly;

in a case that the flexible screen is driven to fold by the first housing and the second housing, the driving member drives the driving rod to rotate along a first driving direction, to cause the driving rod to drive the transmission gear assembly to rotate along the first direction; and

in a case that the flexible screen is driven to unfold by the first housing and the second housing, the driving member drives the driving rod to rotate along a second driving direction, to cause the driving rod to drive the transmission gear assembly to rotate along the second direction, wherein

the first driving direction and the second driving direction are reverse.

7 . The electronic device according to claim 2 , wherein a support is arranged on the first housing, and the transmission rod is rotatably connected to the support;

a rotation groove is provided on the support; and at least a portion of the transmission rod is located in the rotation groove, and the first transmission insection is located in external space of the rotation groove.

8 . The electronic device according to claim 7 , wherein the support comprises a fixing block and a fixing plate, and the fixing plate is detachably connected to the fixing block; and

the fixing block is arranged on the first housing, the rotation groove is provided on the fixing block, and the transmission rod is located between the fixing block and the fixing plate.

9 . The electronic device according to claim 2 , wherein the electronic device further comprises a mounting base; and

the mounting base is connected to the transmission rod, and the stylus is detachably connected to the mounting base.

10 . The electronic device according to claim 9 , wherein a mounting groove is provided on the mounting base, a first magnetic member is arranged in the mounting groove, a second magnetic member is arranged on a mounting end of the stylus, the mounting end of the stylus is located in the mounting groove, and magnetism of the first magnetic member and magnetism of the second magnetic member are opposite.
