Abstract

An electronic device with an elevating mechanism includes a body and the elevating mechanism connected with the body. The elevating mechanism includes a support base, an elevating element, and a fastening element. The elevating element capable of moving between a first position and a second position relative to the support base is connected with both the support base and the body. The elevating element includes a first wedging component. The fastening element disposed around the second position relative to the support base is rotatable between a third position and a fourth position. The fastening element includes a second wedging component. When the fastening element is rotated to the fourth position, the second wedging component is wedged on the first wedging component for fastening the elevating element at the second position.

Claims (32)

1. An elevating mechanism comprising:

a support base;

an elevating element connected to the support base and capable of moving relative to the support base between a first position and a second position, the elevating element having a first wedging component; and

a fastening element, disposed on the support base, located near the second position, and capable of rotating relative to the support base between a third position and a fourth position, the fastening element having a second wedging component, the fastening element comprising:

a pivot disposed on the support base; and

a cam disposed on the pivot, the cam having a first side and a second side, the second wedging element disposed at the first side or the second side of the cam;

wherein when the fastening element is rotated to the fourth position, the second wedging component is wedged on the first wedging component for fastening the elevating element at the second position.

2. The elevating mechanism of claim 1 wherein the fastening element further comprises a handle disposed at one terminal of the pivot for rotating the pivot.

3. The elevating mechanism of claim 1 wherein the fastening element further comprises:

a twist force device having a first terminal and a second terminal, the second terminal of the twist force device fastened on the first side of the cam, the first terminal of the twist force device fastened on the support base.

4. The elevating mechanism of claim 3 wherein the twist force device is a twist spring.

5. The elevating mechanism of claim 1 wherein the fastening element further comprises:

a twist force device having a first terminal and a second terminal, the first terminal of the twist force device fastened at the second side of the cam, the second terminal of the twist force device fastened on the support base.

6. The elevating mechanism of claim 5 wherein the twist force device is a twist spring.

7. The elevating mechanism of claim 1 wherein the first wedging component comprises a first cambered surface; wherein the second wedging component comprises a second cambered surface corresponding to the first cambered surface; wherein when the elevating element is located at the second position, the first cambered surface resists against the second cambered surface.

8. An electronic device with an elevating mechanism comprising:

a body; and

an elevating mechanism connected to the body, the elevating mechanism comprising:

a support base;

an elevating element connected to both the support base and the body, the elevating element capable of moving relative to the support base between a first position and a second position, the elevating element having a first wedging component; and

a fastening element disposed on the support base and located near the second position, the fastening element capable of rotating relative to the support base between a third position and a fourth position, the fastening element having a second wedging component, the fastening element comprising:

a pivot disposed on the support base; and

a cam disposed on the pivot, the cam having a first side and a second side, the second wedging element disposed at the first side or the second side of the cam;

wherein when the fastening element is rotated to the fourth position, the second wedging component is wedged on the first wedging component for fastening the elevating element at the second position.

9. The electronic device of claim 8 wherein the fastening element further comprises a handle disposed at one terminal of the pivot for rotating the pivot.

10. The electronic device of claim 8 wherein the fastening component further comprises:

a twist force device having a first terminal and a second terminal, the second terminal of the twist force device fastened at the first side of the cam, the first terminal of the twist force device fastened on the support base.

11. The electronic device of claim 10 wherein the twist force device is a twist spring.

12. The electronic device of claim 8 wherein the fastening element further comprises:

a twist force device having a first terminal and a second terminal, the first terminal of the twist force device fastened at the second side of the cam, the second terminal of the twist force device fastened on the support base.

13. The electronic device of claim 12 wherein the twist force device is a twist spring.

14. The electronic device of claim 8 wherein the first wedging component has a first cambered surface, the second wedging component has a second cambered surface corresponding to the first cambered surface; wherein when the elevating element is located at the second position, the first cambered surface resists against the second cambered surface.
