Abstract

A hinge is provided. The hinge includes a first connection element, a second connection element, a first elastic element, and a second elastic element. The second connection element is connected to the first connection element. The first elastic element is connected to the first connection element. The second elastic element is connected to the first elastic element. The first elastic element drives the second elastic element to rotate relative to the second connection element. The first elastic element is rotatable between a first limit position and a second limit position. When the first elastic element is in the first limit position, the second elastic element is compressed.

First claim

What is claimed is:

1. A hinge, comprising:
a first connection element;
a second connection element connected to the first connection element;
a first elastic element connected to the first connection element; and
a second elastic element connected to the first elastic element;
wherein the first elastic element drives the second elastic element to rotate relative to the second connection element, the first elastic element is rotatable between a first limit position and a second limit position, and when the first elastic element is in the first limit position, the second elastic element is compressed.

2. The hinge as claimed in claim 1 , wherein the second connection element comprises a closed state stop, and when the first elastic element is in the second limit position, the second elastic element is in contact with the closed state stop.

3. The hinge as claimed in claim 1 , wherein during the rotation of the first elastic element from the first limit position to the second limit position, the second elastic element interferes with the second connection element.

4. The hinge as claimed in claim 1 , wherein the first elastic element and the second elastic element are integrally formed.

5. The hinge as claimed in claim 1 , further comprising a pin passing through the first connection element.

6. The hinge as claimed in claim 5 , wherein the second connection element further comprises a connection portion, and a distance between the pin and the connection portion of the second connection portion remains the same.

7. The hinge as claimed in claim 5 , further comprising a fixing element for fixing part of the first connection element to part of the second connection element.

8. The hinge as claimed in claim 7 , wherein a central axis of the pin overlaps a central axis of the fixing element.

9. The hinge as claimed in claim 1 , wherein the first connection element comprises a pillar, the first elastic element comprises a bent portion, and the bent portion of the first elastic element surrounds the pillar of the first connection portion.

10. The hinge as claimed in claim 9 , wherein the second connection element comprises a receiving portion, the receiving portion of the second connection portion is hollow and ring-shaped, and the pillar of the first connection portion is received in the receiving portion of the second connection element.

11. The hinge as claimed in claim 1 , wherein the first connection element comprises a receiving portion, the first elastic element comprises an extending portion, and the extending portion is disposed on the receiving portion of the first connection element.

12. The hinge as claimed in claim 1 , wherein the second elastic element is substantially capsule-shaped.

13. A smart wearable device, comprising:
a body;
an arm; and
a hinge, comprising:
a first connection element disposed on the arm;
a second connection element disposed on the body;
a first elastic element connected to the first connection element; and
a second elastic element connected to the first elastic element;

wherein the arm is rotatable toward and away from a central point of the body via the hinge;
wherein when the smart wearable device is not applied by an external force, the hinge is in an initial state, the arm is rotatable away from the central point of the body until the hinge is in a first limit state, and the arm is rotatable toward the central point of the body until the hinge is in a second limit state;
wherein the body comprises an open state stop, and when the hinge is in the first limit state, the arm is in contact with the open state stop, and the second elastic element is compressed.

14. The smart wearable device as claimed in claim 13 , wherein the second connection element comprises a closed state stop, and when the hinge is in the second limit state, the second elastic element is in contact with the closed state stop.

15. The smart wearable device as claimed in claim 13 , wherein an angle between the arm when the hinge is in the initial state and the arm when the hinge is in the first limit state is between about 0° and about 30°.

16. The smart wearable device as claimed in claim 13 , wherein the angle between the arm when the hinge is in the initial state and the arm when the hinge is in the first limit state is about 18°.

17. The smart wearable device as claimed in claim 13 , wherein an angle between the arm when the hinge is in the initial state and when the hinge is in the second limit state is about 80°.

18. The smart wearable device as claimed in claim 17 , wherein the first connection element comprises a connection portion and a connection hole, the connection portion is plate-shaped, the connection hole is formed on the connection portion, and the first connection element is disposed on the arm via the connection portion and the connection hole.

19. A smart wearable device, comprising:
a body;
an arm; and
a hinge, comprising:
a first connection element disposed on the arm;
a second connection element disposed on the body;
a first elastic element connected to the first connection element; and
a second elastic element connected to the first elastic element;
wherein the arm is rotatable toward and away from a central point of the body via the hinge;
wherein when the smart wearable device is not applied by an external force, the hinge is in an initial state, the arm is rotatable away from the central point of the body until the hinge is in a first limit state, and an angle between the arm when the hinge is in the initial state and the arm when the hinge is in the first limit state is between about 0° and about 30°.

20. The smart wearable device as claimed in claim 19 , wherein the hinge further comprises a pin passing through the first connection element.
