Abstract

An adjustable optical lens and camera module, and manufacturing method and applications thereof is disclosed. The camera module includes an optical sensor and an adjustable optical lens. The adjustable optical lens includes an optical structural member and at least two lenses, wherein each of the lenses is arranged in an internal space of the optical structural member. Along a vertical direction of the optical structural member, at least one lens is adapted to be adjustably pre-mounted to an internal space of the optical structural member serving as an adjustable lens. The side wall of the optical structural member is provided with at least one adjustment channel, which is positioned corresponding to the adjustable lens, so that an assembling position of the adjustable lens can be adjusted through the adjustment channel so as to align a central axis line of the adjustable optical lens with a central axis line of the optical sensor.

First claim

What is claimed is:

1. A camera module, comprising:
a photosensitive device including an optical sensor; and
an adjustable optical lens member which is arranged in a photo sensitive path of said optical sensor and comprises an optical structural member, one or more lenses and an aperture member, wherein each of said lenses is arranged in an internal space of said optical structural member, wherein at least one of said lenses is preassembled in said internal space of said optical structural member serving as an adjustable lens, wherein said aperture member has at least one adhesive injection channel extended corresponding to said adjustable lens, such that after said adjustable lens is adjusted through at least one adjustment channel in said optical structural member, said adhesive injection channel is guided for adjusting an assembling position of said aperture member, adjusting an assembling position of said adjustable lens, and injecting adhesive into said internal space of said optical structural member through said adhesive injecting channel to affix a position of said adjustable lens, wherein when said adjustable lens is adjusted inside said internal space of said optical structural member, a position of said adjustable lens is affixed by adhesive, so as to fix a relative position between said adjustable lens and said photosensitive device after the adjustable optical lens member and the photosensitive device is packaged to complete the assembling of the camera module.

2. The camera module, as recited in claim 1 , wherein said at least one adjustment channel is provided non-parallel to said adhesive injection channel for communicating said internal space of said optical structural member with outside, wherein said at least one adjustment channel is positioned corresponding to said one or more lenses to be preassembled and arranged in said internal space of said optical structural member, wherein each of said one or more lenses which is preassembled in said internal space of said optical structural member is able to be adjusted through said at least one adjustment channel before packaging said adjustable lens and said photosensitive device.

3. The camera module, as recited in claim 2 , wherein said photosensitive device comprises a filter, a lens mount and a circuit board, wherein said filter is affixed on said lens mount and said optical sensor is attached on said circuit board and positioned below said filter, wherein the optical structural member is affixed on a top side of the lens mount.

4. The camera module, as recited in claim 2 , wherein said photosensitive device comprises a filter and a circuit board, wherein said filter is installed in said optical structural member and positioned below said one or more lenses, wherein said optical sensor is attached on said circuit board and positioned below said filter, wherein a space distance between said optical structural member with respect to said optical sensor is fixed.

5. The camera module, as recited in claim 1 , wherein each of said one or more lenses of said adjustable optical lens member in said internal space of said optical structural member is able to be adjusted in at least one direction, wherein a central axis line of each of said one or more lenses and a central axis line of said optical sensor are coincided or within an allowable range of deviation therebetween after adjustment of said one or more lenses.

6. The camera module, as recited in claim 5 , wherein said photosensitive device comprises a filter, a lens mount and a circuit board, wherein said filter is affixed on said lens mount and said optical sensor is attached on said circuit board and positioned below said filter, wherein the optical structural member is affixed on a top side of the lens mount.

7. The camera module, as recited in claim 5 , wherein said photosensitive device comprises a filter and a circuit board, wherein said filter is installed in said optical structural member and positioned below said one or more lenses, wherein said optical sensor is attached on said circuit board and positioned below said filter, wherein a space distance between said optical structural member with respect to said optical sensor is fixed.

8. The camera module, as recited in claim 2 , wherein each of said one or more lenses of said adjustable optical lens member in said internal space of said optical structural member is able to be adjusted in at least one direction, wherein a central axis line of each of said one or more lenses and a central axis line of said optical sensor are coincided or within an allowable range of deviation therebetween after adjustment of said one or more lenses.

9. The camera module, as recited in claim 8 , wherein said photosensitive device comprises a filter, a lens mount and a circuit board, wherein said filter is affixed on said lens mount and said optical sensor is attached on said circuit board and positioned below said filter, wherein the optical structural member is affixed on a top side of the lens mount.

10. The camera module, as recited in claim 8 , wherein said photosensitive device comprises a filter and a circuit board, wherein said filter is installed in said optical structural member and positioned below said one or more lenses, wherein said optical sensor is attached on said circuit board and positioned below said filter, wherein a space distance between said optical structural member with respect to said optical sensor is fixed.

11. The camera module, as recited in claim 1 , wherein said photosensitive device comprises a filter, a lens mount and a circuit board, wherein said filter is affixed on said lens mount and said optical sensor is attached on said circuit board and positioned below said filter, wherein the optical structural member is affixed on a top side of the lens mount.

12. The camera module, as recited in claim 1 , wherein said photosensitive device comprises a filter and a circuit board, wherein said filter is installed in said optical structural member and positioned below said one or more lenses, wherein said optical sensor is attached on said circuit board and positioned below said filter, wherein a space distance between said optical structural member with respect to said optical sensor is fixed.

13. The camera module, as recited in claim 1 , wherein said aperture member is arranged on top of said optical structural member and on a top side of said adjustable lens preassembled, wherein said at least one adjustable injection channel is located at a side of said photo sensitive path of said optical sensor.

14. The camera module, as recited in claim 13 , wherein before packaging said adjustable lens and said photosensitive device, an assembling position of said one or more lenses inside said optical structural member is arranged to be adjusted under said aperture member, so as to change a relative position between said aperture member and said one or more lenses and a relative position between said one or more lenses and said optical sensor.

15. The camera module, as recited in claim 1 , wherein before packaging said adjustable lens and said photosensitive device, an assembling position of said one or more lenses inside said optical structural member is arranged to be adjusted under said aperture member, so as to change a relative position between said aperture member and said one or more lenses and a relative position between said one or more lenses and said optical sensor.
