Abstract

A cover operation mechanism includes a case, a cover rotatably coupled to the case, a positioning portion located on the case, and a driver engaged with the positioning portion. The case includes a receiving portion. The cover covers the receiving portion and includes a shaft slidable and mounted in the slot. The driver includes an elastic element. When the cover is covered on the receiving portion, the driver drives the shaft to make the elastic element generate an elastic force. When the cover is disengaged from the receiving portion by an external force, the elastic force drives the shaft to be moved from one end to an opposite end of the slot to open the cover.

First claim

What is claimed is:

1. A cover operation mechanism, comprising:
a case comprising a receiving portion;
a cover rotatably coupled to the case to cover the receiving portion, comprising a shaft;
a positioning portion located on the case and defining a slot, wherein the shaft is slidingly mounted in the slot; and
a driver engaged with the positioning portion, comprising an elastic element, a main body and a pin, the pin is passed through the main body and making the main body to be coupled to the case, and the elastic element sleeved on the pin and coupled to the main body and the case;
wherein when the cover is covered on the receiving portion, the driver drives the shaft to make the elastic element generate an elastic force;
wherein when the cover is disengaged from the receiving portion by an external force, the elastic force drives the shaft to be moved from an end to an opposite end of the slot to open the cover.

2. The cover operation mechanism of claim 1 , wherein the elastic element is located in the main body, a first end portion of the main body is rotatably coupled to the case, and a second end portion of the main body is engaged with the shaft.

3. The cover operation mechanism of claim 2 , wherein the second end portion has a smooth surface, and the shaft defines a groove engaging with the second end portion.

4. The cover operation mechanism of claim 3 , wherein the positioning portion comprises a pair of first positioning blocks, the slot is defined in the first positioning block.

5. The cover operation mechanism of claim 4 , wherein the positioning portion further comprises a pair of second positioning blocks located between the pair of the first positioning blocks, and the pin is mounted in the second positioning blocks.

6. The cover operation mechanism of claim 1 , wherein the receiving portion is concaved from the case, one of the receiving portion and the cover defines a first recess and the other comprises a first latching portion engaging with the first recess.

7. The cover operation mechanism of claim 6 , wherein, a cylinder protrudes from the first latching portion and slides along the first recess to make the first latching portion engage with the first recess or disengage from the first recess.

8. The cover operation mechanism of claim 6 , wherein the cover further comprises a pair of connecting arms, the pair of connecting arms is inserted into the case to couple to the shaft.

9. A cover operation mechanism, comprising:
a case comprising a receiving portion, and a sunken portion adjacent to the receiving portion;
a cover rotatably coupled to the sunken portion to cover the receiving portion, comprising a shaft;
a positioning portion located on the case and defining a slot, wherein the shaft is slidingly mounted in the slot; and
a driver engaged with the positioning portion, comprising an elastic element, a main body and a pin, the pin is passed through the main body and making the main body to be coupled to the case, and the elastic element sleeved on the pin and coupled to the main body and the case;
wherein when the cover is covered on the receiving portion, the driver drives the shaft to make the elastic element generate an elastic force and the cover is aligned with the case;
wherein when the cover is disengaged from the receiving portion by an external force, the elastic force drives the shaft from an end to an opposite end of the slot to open the cover.

10. The cover operation mechanism of claim 9 , wherein the elastic element is located in the main body, a first end portion of the main body is rotatably coupled to the case, and a second end portion of the main body is engaged with the shaft.

11. The cover operation mechanism of claim 10 , wherein the second end portion has a smooth surface, and the shaft defines a groove engaging with the second end portion.

12. The cover operation mechanism of claim 11 , wherein the positioning portion comprises a pair of first positioning blocks, the slot is defined in the first positioning block.

13. The cover operation mechanism of claim 12 , wherein the positioning portion further comprises a pair of second positioning blocks located between the pair of the first positioning blocks, and the pin is mounted in the second positioning blocks.

14. The cover operation mechanism of claim 9 , wherein the receiving portion is concaved from the case, one of the receiving portion and the cover defines a first recess and the other comprises a first latching portion engaging with the first recess.

15. The cover operation mechanism of claim 14 , wherein, a cylinder protruding from the first latching portion and slides along the first recess to make the first latching portion engage with the first recess or disengage from the first recess.

16. The cover operation mechanism of claim 14 , wherein the cover further comprises a pair of connecting arms, the pair of connecting arms is inserted into the case to couple to the shaft.

17. A cover operation mechanism, comprising:
a case comprising a receiving portion;
a cover rotatably coupled to the case to cover the receiving portion, comprising a shaft;
a positioning portion located on the case and defining a slot, and the shaft slidingly mounted in the slot; and
a driver engaged with the positioning portion, comprising a main body, an elastic element located on the main body, and a pin, the pin is passed through the main body and making the main body to be coupled to the case, and the elastic element sleeved on the pin and coupled to the main body and the case;
wherein when the cover is covered on the receiving portion, the driver drives the shaft to make the elastic element generate an elastic force and the main body is perpendicular to the case;
wherein when the cover is disengaged from the receiving portion by an external force, the elastic force drives the shaft to be moved from an end to an opposite end of the slot to make the cover be opened and the main body is gradually inclined with the case.

18. The cover operation mechanism of claim 17 , wherein a first end portion of the main body is rotatably coupled to the case, a second end portion of the main body is engaged with the shaft, the second end portion has a smooth surface, and the shaft defines a groove engaging with the second end portion.
