Abstract

A lens structure is provided. The lens structure comprises a first barrel and a second barrel. The first barrel comprises a first pin and a second pin. The second barrel comprises a continuous groove. Wherein in a wide-angle end, the first pin is located in the continuous groove and the second pin is located outside of the second barrel. Wherein in a telephoto end, the first pin is located outside of the second barrel and the second pin is located in the continuous groove.

First claim

What is claimed is:

1. A lens structure having a wide-angle end, a telephoto end and an axis, comprising: a first barrel comprising a first pin and a second pin; a second barrel comprising a first surface perpendicular to the axis, a second surface opposite to the first surface and a continuous groove extending between the first surface and the second surface and having two openings respectively exposed on the first surface and the second surface; wherein at the wide-angle end, the first pin is inside of the continuous groove and the second pin is outside the second surface of the second barrel; and wherein at the telephoto end, the first pin is outside the first surface of the second barrel and the second pin is inside of the continuous groove, wherein the second barrel further comprises a space, during a collapsed status, the first in inside the continuous groove and the second in inside the space.

2. The lens structure according to claim 1 , wherein the continuous groove comprises a first sub-groove, a second sub-groove and a third sub-groove, the first sub-groove connects to the second sub-groove, the third sub-groove extends to the second surface of the second barrel from the second sub-groove, and the second sub-groove extends to the first surface of the second barrel.

3. The lens structure according to claim 2 , wherein the first sub-groove comprises a first rotation groove, a second rotation groove and a third rotation groove, the second rotation groove connects the first rotation groove and third rotation groove and extends between the first surface and the second surface.

4. The lens structure according to claim 3 , wherein the first rotation groove and the third rotation groove extends around an axis of the second barrel, and the third rotation groove connects to the third sub-groove.

5. The lens structure according to claim 2 , wherein the second sub-groove comprises a fourth rotation groove, a fifth rotation groove and a sixth rotation groove, the fourth rotation groove connects to the fifth rotation groove and extends to the first surface, the fifth rotation groove extends around an axis of the second barrel, the sixth rotation groove connects the fifth rotation groove and the third rotation groove and extends between the first surface and the second surface.

6. The lens structure according to claim 5 , wherein at the wide-angle end, the first pin is adjacent to a junction between the fifth rotation groove and the third rotation groove.

7. The lens structure according to claim 5 , wherein the fourth rotation groove is parallel to the sixth rotation groove, and the third sub-groove is parallel to the sixth rotation groove.

8. The lens structure according to claim 5 , wherein the fourth rotation groove is separated from the sixth rotation groove by a distance along a direction, and the third sub-groove is separated from the sixth rotation groove by the distance along the direction.

9. The lens structure according to claim 5 , wherein at the telephoto end, the second pin is adjacent to a junction between the fourth rotation groove and the fifth rotation groove.

10. The lens structure according to claim 2 , wherein the continuous groove further a fourth sub-groove connects to the continuous groove and extends to the second surface of the second barrel, and during the collapsed status, the first pin is adjacent to a junction between the fourth sub-groove and the first sub-groove.

11. An electronic apparatus comprising the lens structure claimed in claim 1 .

12. A lens structure, zooming from a wide-angle end to a telephoto end and having an axis, comprising: a first barrel comprising a first pin group and a second pin group; and a second barrel comprising a first surface perpendicular to the axis, a second surface opposite to the first surface and a continuous groove having two openings respectively exposed on the first surface and the second surface; wherein from the wide-angle end to the telephoto end, the first pin group slides in accordance with the continuous groove and be detached from the second barrel from the first surface; and wherein during the first pin group detaching from the second barrel, the second pin group slides in accordance with the continuous groove, wherein the second barrel further comprises a space, during the collapsed status, the first pin is inside the continuous groove and the second pin is inside the space.

13. An electronic apparatus comprising the lens structure claimed in claim 12 .

14. A lens structure, zooming between a wide-angle end and a telephoto end and having an axis, and stored in a collapsed status, the lens structure comprising: a first barrel comprising a first pin and a second pin; and a second barrel comprising a first surface perpendicular to the axis, a second surface perpendicular to the axis and a continuous groove having two openings respectively exposed on the first surface and the second surface; wherein the first barrel slides in accordance with the continuous groove by the first pin and the second pin respectively to relatively move to the second barrel; wherein at the wide-angle end, the first pin is inside of the continuous groove and the second pin is outside the second surface of the second barrel via the opening exposed on the second surface; and wherein at the telephoto end, the first pin is outside the first surface of the second barrel via the opening exposed on the first surface and the second pin is inside of the continuous groove, wherein the second barrel further comprises a space, in a collapsed status, the first pin is inside the continuous groove and the second pin is inside the space.

15. An electronic apparatus comprising the lens structure claimed in claim 14 .
