Abstract

A computer with a projecting device comprises: a base shell, disposed with a top face, the top face being disposed with an opening, the opening communicating an inner part of the base shell; an expansible structure, comprising a first unit, a second unit and a third unit, in which first bottom end of the first unit is pivotally coupled to the base shell through at least one first pivot unit, a second bottom of the second unit is pivotally coupled to the first unit through at least one second pivot unit and the third unit is pivotally coupled to the second unit through a pivot structure; a first face of the third unit is coupled to a projection lens module to allow a height of the projection lens module to be changed and a projection direction thereof to be adjusted.

Claims

1. A computer with a projecting device, comprising:

a base shell, disposed with a top face and a switching mechanism, said top face being disposed with an opening, said opening communicating an inner part of said base shell, said switching mechanism being disposed with an interference element, and said interference element being adapted to generate a mechanical interference action;

a projection lens module, used for projecting out images;

an expansible structure, comprising a first unit, a second unit and a third unit, said first unit having a first bottom end and a first top end;

said first bottom end being pivotally coupled to said base shell through at least one first pivot unit, said second unit having a second bottom end and a second top end, said second bottom end being pivotally coupled to said first unit through at least one second pivot unit, said third unit being pivotally coupled to said second unit through a pivot structure, said third unit being disposed with a first face and a buckling unit and said first face being coupled to said projection lens module thereby allowing said first top end to be risen toward a position above said top face, said second unit and said third unit to be risen toward a position above said first unit and a projection direction of said project ion lens module to be adjusted rotationally in relation to said second unit;

wherein, said first unit, said second unit and said third unit are accepted in said opening after being collected, and said expansible structure being further allowed to maintain in a state of being placed in said opening when said interference element and said buckling unit are interfered with each other.

2. The computer with a projecting device according to claim 1, wherein said first pivot unit is a hinge, said first top end is caused to rise automatically toward a position above said top face through said first pivot unit when said first unit is not limited by an external force.

3. The computer with a projecting device according to claim 2, wherein said second pivot unit is a hinge, said second top end is caused to rise automatically toward a position above said first top end through said second pivot unit when said second unit is not limited by an external force.

4. The computer with a projecting device according to claim 3, wherein said pivot structure is disposed with a fixing element and a movable element, said fixing element is placed under said movable element;

said fixing element is pivotally coupled to said second unit through a third pivot unit;

wherein said third pivot unit is a hinge, said movable element is caused to rise automatically toward a position above said second top end through said third pivot unit when said pivot structure is not limited by an external force.

5. The computer with a projecting device according to claim 4, wherein said first pivot unit, said second pivot unit and said third pivot unit respectively are a damping hinge.

6. The computer with a projecting device according to claim 5, wherein said first pivot unit is placed inside said base shell.

7. The computer with a projecting device according to claim 6, wherein said switching mechanism generates an electric switching action to turn off a power supply providing electricity for said projection lens module when said interference element is interfered with said buckling unit.

8. The computer with a projecting device according to claim 7, wherein said pivot structure is a universal joint.

9. The computer with a projecting device according to claim 8, wherein said second unit is further disposed with an accepting groove thereby accepting said pivot structure and said third unit after being collected.

10. The computer with a projecting device according to claim 9, wherein said buckling unit is a slot disposed on a top end face of said third unit.

11. The computer with a projecting device according to claim 10, wherein a rotating rise direction of said first top end is different from a rotating rise direction of said second top end but respectively is the same as rotating rise directions of said movable element and said first unit.

12. The computer with a projecting device according to claim 1, wherein a rear end of said base shell is pivotally coupled to a projection screen thereby allowing said projection lens module to project images onto said projection screen.

13. The computer with a projecting device according to claim 12, wherein said third unit is disposed with a second face, said second face is coupled to a video camera lens module, said video camera lens module is adapted to capture images.

14. The computer with a projecting device according to claim 13, wherein said switching mechanism generates an electric switching action to turn off a power supply providing electricity for said projection lens module when said interference element is interfered with said buckling unit.

15. The computer with a projecting device according to claim 5, wherein a rear end of said base shell is pivotally coupled to a projection screen thereby allowing said projection lens module to project images onto said projection screen.

16. The computer with a projecting device according to claim 15, wherein said third unit is disposed with a second face, said second face is coupled to a video camera lens module, said video camera lens module is adapted to capture images.

17. The computer with a projecting device according to claim 16, wherein said switching mechanism generates an electric switching action to turn off a power supply providing electricity for said projection lens module when said interference element is interfered with said buckling unit.

18. The computer with a projecting device according to claim 11, wherein a rear end of said base shell is pivotally coupled to a projection screen thereby allowing said projection lens module to project images onto said projection screen.

19. The computer with a projecting device according to claim 18, wherein said third unit is disposed with a second face, said second face is coupled to a video camera lens module, said video camera lens module is adapted to capture images.

20. The computer with a projecting device according to claim 19, wherein said switching mechanism generates an electric switching action to turn off a power supply providing electricity for said projection lens module when said interference element is interfered with said buckling unit.
