Abstract

An electronic device includes a first body, a second body, a hinge structure, an ascending/descending mechanism, and a flexible screen. The hinge structure is located between the first body and the second body, and the first body is connected to the second body through the hinge structure. At least one of the first body and the second body has an accommodating space. The ascending/descending mechanism is disposed in the accommodating space and connected to the hinge structure. The flexible screen includes a first bonding portion fixed to the first body, a second bonding portion fixed to the second body, and a bending portion located between the first and second bonding portions. The bending portion is aligned to the hinge structure and the ascending/descending mechanism. The ascending/descending mechanism is driven by the hinge structure to ascend or descend, so that the bending portion moves out of or into the accommodating space.

First claim

What is claimed is:

1. An electronic device, comprising:
a first body;
a second body;
a hinge structure, located between the first body and the second body, the first body being connected to the second body through the hinge structure, wherein at least one of the first body and the second body has an accommodating space facing the hinge structure;
an ascending/descending mechanism, disposed in the accommodating space and connected to the hinge structure, the ascending/descending mechanism comprising a driving rod, a first driven rod, a support rod, and a second driven rod, two ends of the driving rod being respectively pivotally connected to the hinge structure and the first driven rod, wherein the first driven rod and the second driven rod are arranged in parallel, and the first driven rod and the second driven rod are respectively pivotally connected to two ends of the support rod; and
a flexible screen, comprising a first bonding portion fixed to the first body, a second bonding portion fixed to the second body, and a bending portion located between the first bonding portion and the second bonding portion, wherein the bending portion is aligned to the hinge structure and the ascending/descending mechanism, the support rod contacts the bending portion of the flexible screen, and
the ascending/descending mechanism is configured to be driven by the hinge structure to ascend or descend, such that the bending portion of the flexible screen moves out of or moves into the accommodating space.

2. The electronic device as claimed in claim 1 , wherein the ascending/descending mechanism further comprises a support plate fixed to the support rod, and the support rod contacts the bending portion of the flexible screen through the support plate.

3. The electronic device as claimed in claim 1 , wherein the ascending/descending mechanism further comprises a first rotation fulcrum and a second rotation fulcrum fixed into the accommodating space, the first driven rod is pivotally connected to the first rotation fulcrum, and the second driven rod is pivotally connected to the second rotation fulcrum.

4. The electronic device as claimed in claim 3 , wherein a pivot point of the driving rod on the first driven rod is located between the support rod and the first rotation fulcrum.

5. The electronic device as claimed in claim 1 , wherein the first body is pivotally connected to the hinge structure along a first axis, the second body is pivotally connected to the hinge structure along a second axis, the driving rod is pivotally connected to the hinge structure along a third axis, and the first axis, the second axis, and the third axis are parallel to each other.

6. The electronic device as claimed in claim 1 , wherein the hinge structure comprises a hinge housing and a holder base, the holder base is disposed in the hinge housing, and the driving rod extends into the hinge housing and is pivotally connected to the holder base.

7. The electronic device as claimed in claim 6 , further comprising a first bracket and a second bracket, each of the first bracket and the second bracket comprises a fixing portion and a rotating shaft portion, the fixing portion of the first bracket is fixed to the first body, the rotating shaft portion of the first bracket is pivotally connected to the hinge housing, the fixing portion of the second bracket is fixed to the first body, and the rotating shaft portion of the second bracket is pivotally connected to the hinge housing.

8. The electronic device as claimed in claim 7 , wherein the rotating shaft portion of the first bracket and the rotating shaft portion of the second bracket are arranged in parallel in the hinge housing.

9. The electronic device as claimed in claim 7 , further comprising a third bracket and a fourth bracket, wherein each of the third bracket and the fourth bracket comprises a fixing portion and a pivot portion, the fixing portion of the third bracket is fixed to the first body, the pivot portion of the third bracket is pivotally connected to the holder base, the fixing portion of the fourth bracket is fixed to the second body, and the pivot portion of the fourth bracket is pivotally connected to the holder base.

10. The electronic device as claimed in claim 9 , wherein the pivot portion of the third bracket and the pivot portion of the fourth bracket are arranged in parallel in the hinge housing.

11. The electronic device as claimed in claim 1 , wherein each of the first body and the second body has the accommodating space facing the hinge structure, the number of the ascending/descending mechanism is two, and the two ascending/descending mechanisms are respectively disposed in the accommodating space of the first body and the accommodating space of the second body.
