Abstract

An electronic device includes a first body, a second body, a rotary shaft and a flexible display panel. The second body is movably connected to the first body and is adapted to lean against the first body or separate from the first body. The rotary shaft is pivotally connected to the first body. The flexible display panel is connected between the first and second bodies. When the second body is at the first position, a first section of the flexible display panel is rolled around the rotary shaft, and a second section of the flexible display panel is expanded between the first and second bodies. When the second body is at the second position, a part of the first section and the second section are expanded between the first and second bodies.

First claim

What is claimed is:

1. An electronic device, comprising:
a first body;
a second body, movably connected to the first body, wherein the second body is adapted to move to a first position so as to lean against the first body or move to a second position so as to separate from the first body;
a rotary shaft, pivotally connected to the first body;
a fixed shaft, wherein the fixed shaft is fixed to the second body;
a flexible display panel, connected between the rotary shaft and the fixed shaft, wherein when the second body is at the first position, a first section of the flexible display panel is rolled around the rotary shaft, and a second section of the flexible display panel is expanded between the first body and the second body, and the second section of the flexible display panel is located outside the first body and the second body, and
at least one first rod and at least one second rod, wherein an end of the first rod is pivotally connected to the first body, an end of the second rod is pivotally connected to the second body, the other end of the first rod is pivotally connected to the other end of the second rod, and the second body moves between the first position and the second position through rotations of the first rod and the second rod,
when the second body is at the second position, a part of the first section and the second section are expanded between the first body and the second body.

2. The electronic device of claim 1 , wherein when the second body is at the second position, an included angle between the first rod and the second rod is less than 180 degree.

3. The electronic device of claim 1 , wherein a thickness of the first body is equal to a thickness of the second body.

4. The electronic device of claim 3 , further comprising a main board and a battery, wherein the main board is disposed in the first body, and the battery is disposed in the second body.

5. The electronic device of claim 1 , wherein a thickness of the first body is larger than a thickness of the second body, the first body has a concave portion, and when the second body is at the first position, the second body leans against the concave portion.

6. The electronic device of claim 5 , further comprising a main board and a battery, wherein the main board and the battery are disposed in the first body.

7. The electronic device of claim 1 , further comprising a first elastic member, wherein the first elastic member is connected between the rotary shaft and the first body, and tension of the flexible display panel is generated by elastic force of the first elastic member.

8. The electronic device of claim 1 , further comprising a cable and a main board, wherein the main board is disposed in the first body, a first connecting end of the flexible display panel is connected to the rotary shaft, and the cable is connected between the first connecting end and the main board.

9. The electronic device of claim 8 , further comprising a cable storage structure, wherein the cable storage structure comprises:
a casing, disposed in the first body;
a sliding member, slidably disposed at the casing, wherein the cable passes through the sliding member, and when the second body is at the first position, the cable is extended in the casing partially; and
a second elastic member, connected between the casing and the sliding member, wherein when the second body is moved from the first position to the second position, the rotary shaft is rotated so that at least a part of the cable inside the casing is rolled around the rotary shaft, and the sliding member is pulled by the cable to slide along the casing by resisting elastic force of the second elastic member.

10. The electronic device of claim 9 , wherein the sliding member has an extending portion, the extending portion has an opening, the second elastic member is connected to the opening of the extending portion, and the cable is disposed at the extending portion of the sliding member by passing through the opening of the extending portion.

11. The electronic device of claim 8 , wherein the rotary shaft has a first groove and a second groove, the first groove is extended along an axial direction of the rotary shaft, the second groove is circular and connected to the first groove, and the cable is extended from the flexible display panel to the second groove along the first groove and rolled in the second groove partially.

12. The electronic device of claim 1 , further comprising a cable and a main board, wherein the main board is disposed in the first body, a second connecting end of the flexible display panel is connected to the second body, and the cable is connected between the second connecting end and the main board.

13. The electronic device of claim 12 , further comprising at least one first rod and at least one second rod, wherein an end of the first rod is pivotally connected to the first body, an end of the second rod is pivotally connected to the second body, the other end of the first rod is pivotally connected to the other end of the second rod, and the second body moves between the first position and the second position through rotations of the first rod and the second rod.

14. The electronic device of claim 13 , the cable is extended from the second body to the first body along the first rod and the second rod so as to connect to the main board.

15. The electronic device of claim 1 , wherein the first body has a first magnetic member, the second body has a second magnetic member, when the second body is at the first position, the first magnetic member is aligned with the second magnetic member, and the second body is fixed to the first body via a magnetic attractive force between the first magnetic member and the second magnetic member.

16. The electronic device of claim 15 , wherein the first body has a first electromagnet, the second body has a second electromagnet, when the second body is at the first position, the first electromagnet is aligned with the second electromagnet, a magnetic repulsive force is adapted to be generated between the first electromagnet and the second electromagnet, and the second body moves to the second position by the magnetic repulsive force resisting the magnetic attractive force.
