Lens module
The present disclosure provides a lens module, including a lens barrel and a lens group. The lens group including at least one lens, and the lens barrel including an inside surface and an outside surface. The lens includes an optical portion and a bearing portion. The bearing portion includes an object side, an image side, a lateral surface and an inclined surface. The inside surface includes a first abutting surface, an extend surface and a second abutting surface, the lateral surface abutting against the first abutting surface, the lateral surface is provided with a protrusion extending from the lateral surface towards the second abutting surface. The protrusion is separated from the second abutting surface. The protrusion, the lateral surface, the extend surface and the second abutting surface form a first adhesive accommodation slot, and the inclined surface, the protrusion and the second abutting surface form a second adhesive accommodation slot.
1. A lens module, comprising a lens barrel provided with an optical aperture and a lens group disposed in the lens barrel,
the lens group comprising at least one lens, and
the lens barrel comprising an inside surface abutting against the lens and an outside surface disposed opposite to the inside surface,
wherein
the lens comprises an optical portion and a bearing portion disposed around the optical portion,
the bearing portion comprises an object side facing a side of an object, an image side disposed opposite to the object side, a lateral surface connecting the object side and the image side, and an inclined surface connecting the lateral surface and the image side,
the inside surface comprises a first abutting surface abutting against the lens, an extend surface bending and extending from the first abutting surface in a direction away from an optical axis and a second abutting surface connecting the extending surface,
the lateral surface abutting against the first abutting surface, the lateral surface is provided with a protrusion extending from the lateral surface to the second abutting surface, the protrusion being separated from the second abutting surface,
the protrusion, the lateral surface, the extend surface and the second abutting surface forming a first adhesive accommodation slot, and
the inclined surface, the protrusion and the second abutting surface forming a second adhesive accommodation slot.
2. The lens module according to the claim 1 , wherein the protrusion comprises a fixing portion fixed to the lateral surface, and a perpendicular portion perpendicularly extending from an end of the fixing portion away from the lateral surface toward the image side.
3. The lens module according to the claim 2 , wherein the protrusion is disposed around the bearing portion.
4. The lens module according to the claim 1 , wherein the lens module further comprises a light-shielding member bonded to the lens.
5. The lens module according to the claim 4 , wherein the light-shielding member is a hollow annular structure.
