Abstract

A foldable electronic device including a first body, a second body, a hinge module and a shielding sheet is provided. The hinge module is pivotally connected to the first body and the second body. The shielding sheet covers the hinge module. The shielding sheet includes an inner film and an outer film overlapping each other, and the inner film is fixed to the hinge module.

First claim

What is claimed is:

1. A foldable electronic device, comprising:
a first body;
a second body;
a hinge module pivotally connected to the first body and the second body; and
a shielding sheet covering the hinge module, the shielding sheet comprising an inner film and an outer film overlapping each other, the inner film being fixed to the hinge module, wherein a sheet fixed section of the shielding sheet and the hinge module do not slide relative to each other, and the sheet fixed section of the shielding sheet is fixed at an inner side of the hinge module.

2. The foldable electronic device according to claim 1 , wherein the inner film is a film of low ductility, the outer film is a film of high ductility, and the ductility of the inner film is smaller than the ductility of the outer film.

3. The foldable electronic device according to claim 1 , wherein the inner film is a flexible plastic film, a tough metal film, or a composite film comprising rigid metal and flexible plastic.

4. The foldable electronic device according to claim 1 , wherein the outer film is an elastic plastic film, elastic leather or an elastic coating film.

5. The foldable electronic device according to claim 1 , wherein the shielding sheet further comprises a first deformation section.

6. The foldable electronic device according to claim 5 , wherein the shielding sheet further comprises a first movable section located on one side of the first deformation section and extending into the first body along a first extension direction.

7. The foldable electronic device according to claim 6 , wherein the first movable section further comprises a first guide groove parallel to the first extension direction.

8. The foldable electronic device according to claim 7 , wherein the first body further comprises a first guide portion movably disposed in the first guide groove.

9. The foldable electronic device according to claim 8 , wherein when the first body and the second body are closed parallel to each other, the first deformation section has a first closing width, and when the first body and the second body are expanded parallel to each other, the first deformation section has a first expansion width, and the first closing width is smaller than the first expansion width.

10. The foldable electronic device according to claim 9 , wherein the shielding sheet further comprises a second deformation section, the shielding sheet further comprises a second movable section located on one side of the second deformation section and extending into the second body along a second extension direction, the second movable section further comprises a second guide groove parallel to the second extension direction, and the second body further comprises a second guide portion movably disposed in the second guide groove, wherein when the first body and the second body are closed parallel to each other, the second deformation section has a second closing width, and when the first body and the second body are expanded parallel to each other, the second deformation section has a second expansion width, and the second closing width is smaller than the second expansion width.

11. The foldable electronic device according to claim 10 , wherein when the first body changes from being closed parallel to the second body to being expanded parallel to the second body, a first displacement of the first guide groove at the first guide portion plus a second displacement of the second guide groove at the second guide portion equals a difference between a sum of the first expansion width and the second expansion width and a sum of the first closing width and the second closing width.

12. The foldable electronic device according to claim 1 , wherein the hinge module is a dual-shaft module comprising a first rotating shaft and a second rotating shaft.

13. The foldable electronic device according to claim 12 , wherein the hinge module further comprises:
a first bracket fixed to the first body and comprising a first sleeve;
a second bracket fixed to the second body and comprising a second sleeve; and
a connection frame comprising a first connection sleeve and a second connection sleeve opposite each other,
wherein the first rotating shaft matches the first sleeve and the first connection sleeve, so as to form a first axis, the second rotating shaft matches the second sleeve and the second connection sleeve, so as to form a second axis, and the first axis and the second axis constitute a geometric plane.

14. The foldable electronic device according to claim 13 , wherein the hinge module further comprises a fixed plate located between the first bracket and the second bracket.

15. The foldable electronic device according to claim 14 , wherein the shielding sheet covers the first bracket, the second bracket, the connection frame and the fixed plate.

16. The foldable electronic device according to claim 14 , wherein the hinge module further comprises a ridge cover opposite the shielding sheet, and the ridge cover covers the first bracket, the second bracket and the connection frame.

17. The foldable electronic device according to claim 16 , wherein the ridge cover is fixed to the connection frame.

18. The foldable electronic device according to claim 14 , wherein when the first body and the second body are expanded parallel to each other, an orthographic projection of the shielding sheet on the geometric plane overlaps orthographic projections of the first sleeve, the second sleeve and the fixed plate on the geometric plane.

19. The foldable electronic device according to claim 13 , wherein when the first body and the second body are closed parallel to each other, an orthographic projection of the shielding sheet on the geometric plane is located between the first axis and the second axis.

20. The foldable electronic device according to claim 1 , wherein the first body is a display module or a touch display module.

21. The foldable electronic device according to claim 1 , wherein the second body is a keyboard input module, a touch input module, a keyboard-and-touch input module, a display module or a touch display module.
