Abstract

An optical lens has a lens component including at least one first lens and a lens barrel portion holding the at least one first lens, an outer part of the lens barrel portion having a first fastener arranged in a circumferential direction, and a lens driving component including a drive portion and a drive portion carrier. The drive portion drives the lens component, and an inner part of the drive portion carrier has a second fastener arranged in a circumferential direction. The first and second fasteners are engaged to couple the lens component and the lens driving component, and one of the first and second fasteners has an inclined portion that is inclinedly configured in the circumferential direction.

First claim

The invention claimed is:

1. An optical lens, comprising:
a lens component including at least one first lens and a lens barrel portion holding the at least one first lens therein, an outer side portion of the lens barrel portion having a first fastener and a first coupling portion arranged in a circumferential direction; and
a lens driving component including a driving portion and a driving portion carrier, the driving portion being configured to drive the lens component, and an inner side portion of the driving portion carrier having a second fastener and a second coupling portion arranged in the circumferential direction,
wherein the first fastener and the second fastener are engaged, and the first coupling portion and the second coupling portion are engaged to jointly couple the lens component and the lens driving component, and
wherein one of the first fastener and the second fastener has an inclined portion inclined relative to the circumferential direction at an upper surface or a lower surface in an optical axis direction so that a lower end of the one of the first fastener and the second fastener enters another of the first fastener and the second fastener through rotation during an assembly process.

2. The optical lens according to claim 1 , wherein the first coupling portion and the second coupling portion include threads or fasteners.

3. The optical lens according to claim 1 , wherein the inclined portion is an inclined surface.

4. The optical lens according to claim 1 , wherein a maximum dimension of the inclined portion in the optical axis direction is the same as a maximum dimension of the another of the first fastener and the second fastener in the optical axis direction.

5. The optical lens according to claim 1 , further comprising a glue material, the glue material being located between the first fastener and the second fastener to bond the lens component and the lens driving component together.

6. The optical lens according to claim 1 , wherein the first fastener is a male fastener, and the second fastener is a female fastener.

7. The optical lens according to claim 6 , wherein at least one of the first fastener and the second fastener includes a boss to prevent the male fastener from releasing from the female fastener.

8. The optical lens according to claim 1 , wherein the first fastener and the second fastener, and the first coupling portion and the second coupling portion are evenly distributed along the circumferential direction.

9. The optical lens according to claim 5 , wherein the glue material is a light curing, thermal curing, moisture curing, anaerobic curing or oxidative curing glue material.

10. The optical lens according to claim 1 , wherein the lens component is a split lens component.

11. An optical lens, comprising:
a lens component including at least one first lens and a lens barrel portion holding the at least one first lens therein, an outer side portion of the lens barrel portion having a first fastener arranged in a circumferential direction; and
a lens driving component including a driving portion and a driving portion carrier, the driving portion being configured to drive the lens component, and an inner side portion of the driving portion carrier having a second fastener arranged in the circumferential direction,
wherein the first fastener and the second fastener are engaged to couple the lens component and the lens driving component, and the first fastener and/or the second fastener has an inclined portion,
wherein the inclined portion is inclined relative to the circumferential direction at an upper surface or a lower surface in an optical axis direction so that a lower end of one of the first fastener and the second fastener enters another of the first fastener and the second fastener through rotation during an assembly process.

12. The optical lens according to claim 11 , wherein the inclined portion is located on the upper surface or the lower surface of the one of the first fastener and the second fastener in the optical axis direction, and is inclined relative to the circumferential direction.

13. The optical lens according to claim 11 , wherein the inclined portion is located on the lower surface of the first fastener and the second fastener in the optical axis direction, and is inclined relative to a radial direction.

14. The optical lens according to claim 12 , wherein a maximum dimension of the inclined portion in the optical axis direction is the same as a maximum dimension of another of the first fastener and the second fastener in the optical axis direction.

15. The optical lens according to claim 11 , wherein the first fastener and the second fastener are configured in two or more layers along the optical axis direction.

16. A method of manufacturing an optical lens, the method comprising:
arranging a first fastener along a circumferential direction of an outer side portion of a lens barrel portion of a lens component, the lens component including at least one first lens and the lens barrel portion holding the at least one first lens therein;
arranging a second fastener along a circumferential direction of an inner side portion of a driving portion carrier of a lens driving component, the lens driving component including a driving portion and the driving portion carrier, the driving portion being configured to drive the lens component;
configuring an inclined portion on the first fastener and/or the second fastener such that the inclined portion is inclined relative to the circumferential direction of the first fastener and/or the second fastener at an upper surface or a lower surface in an optical axis direction;
assembling the lens component and the lens driving component so that a lower end of one of the first fastener and the second fastener enters another of the first fastener and the second fastener through rotation; and
applying a glue material between the first fastener and/or the second fastener to bond the lens component and the lens driving component together.

17. The method of manufacturing an optical lens according to claim 16 , wherein the configuring comprises configuring the inclined portion on the one of the first fastener and the second fastener.

18. The method of manufacturing an optical lens according to claim 16 , wherein the configuring comprises configuring the inclined portion on the lower surface of the first fastener and the second fastener in the optical axis direction and to be inclined relative to a radial direction.

19. The method of manufacturing an optical lens according to claim 16 , wherein the first fastener and the second fastener are configured in two or more layers along the optical axis direction.
