Abstract

A lens module is disclosed. The lens module includes a lens barrel including a first barrel wall extended horizontally and a second barrel wall extended from the first barrel wall; a lens group including at least one lens, the lens includes a first slope; a stop on the first barrel wall and forming a light hole for the lens, and a pressing ring attached to the stop. The first barrel wall of the lens barrel includes a second slope abutting against the first slope for ensuring the concentricity.

First claim

What is claimed is:

1. A lens module, comprising:
a lens barrel having a central axis including a first barrel wall extended at right angles to the central axis and a second barrel wall extended from the first barrel wall along the central axis;
a lens group including at least one lens which includes a first slope;
a stop on the first barrel wall, forming a light hole for the at least one lens; and
a press ring abutting against the stop,
wherein the first barrel wall of the lens barrel includes a second slope abutting against the first slope.

2. The lens module as claimed in claim 1 , wherein: the lens barrel includes a lug extended from an inner surface of the first barrel wall toward the central axis of the lens barrel, and a groove is created by the lug and an inner surface of the lens barrel for at least partially receiving the stop.

3. The lens module as claimed in claim 2 , wherein: the lens barrel is provided with a lug extended from the inner surface of the first barrel wall to the central axis of the lens barrel, and a groove is created by the lug and the inner surface of the lens barrel for partially receiving the stop.

4. The lens module as claimed in claim 3 , wherein a glue groove for receiving the glue is provided between the press ring and the lens barrel.

5. The lens module as claimed in claim 4 , wherein: a third slope is provided at an edge of the press ring, and the third slope and the inner surface of the lens barrel create the glue groove.

6. The lens module according to claim 1 , wherein the press ring is made of plastic or metal.

7. The lens module as claimed in claim 1 , wherein the stop is a hollow ring.

8. The lens module as claimed in claim 1 , wherein an optical axis of the at least one lens, the central axis of the lens barrel and an central axis of the stop are aligned in one straight line.

9. The lens module as claimed in claim 1 , wherein the at least one lens further comprises a protruding central portion and a peripheral portion around the protruding central portion, the protruding central portion extended beyond the light hole along the central axis.

10. The lens module as claimed in claim 9 , wherein a gap is created between the peripheral portion and the stop.
