Abstract
A lens module includes a barrel and at least one lens. The barrel defines a through hole bounded by an inner circumference surface thereof. The inner circumference surface includes at least one first circumference latching surface. The at least one lens includes at least one second circumference latching surface corresponding to the at least one first circumference latching surface. One of the first circumference latching surface and the corresponding second circumference latching surface is a ring-shaped concave surface, and the other is a ring-shaped convex surface latchable with the ring-shaped concave surface.
Claims13
A lens module comprising:
- a barrel comprising a first end, a second end opposite to the first end, and a cap formed at the first end, and defining a through hole bounded by an inner circumference surface thereof, the inner circumference surface substantially parallel to an optical axis of the lens module, and the inner circumference surface comprising at least one first circumference latching surface, the through hole extending from the first end to the second end, the cap defining an opening at the center thereof, and the diameter of the opening being smaller than that of the through hole;
- and
- at least one lens received in the barrel, the at least one lens comprising at least one second circumference latching surface, the at least one first circumference latching surface of the barrel surroundingly latching the at least one second circumference latching surface of the at least one lens,
- wherein, one of the at least one first circumference latching surface and the corresponding at least one second circumference latching surface is a ring-shaped concave surface, and the other is a ring-shaped convex surface latchable with the corresponding ring-shaped concave surface.
A lens module comprising:
- a hollow barrel comprising a first end, a second end opposite to the first end, and a cap formed at the first end and defining a through hole bounded by an inner wall of the barrel, the inner wall comprising a latching portion, the latching portion being generally cylindrical, the through hole extending from the first end to the second end, the cap defining an opening at the center thereof, and the diameter of the opening being smaller than that of the through hole;
- and
- a lens received in the barrel at the latching portion, an outer periphery of the lens being generally cylindrical;
- wherein one of the latching portion and the outer periphery of the lens is in the form of an annular bead with a curved surface, and the other of the latching portion and the outer periphery of the lens is in the form of an annular depression with a curved surface matching the curved surface of the bead, such that the lens is latched in the latching portion.
A lens module comprising:
- a hollow barrel comprising a first end, a second end opposite to the first end, and a cap formed at the first end and defining a through hole bounded by an inner wall of the barrel, the inner wall comprising a latching portion, a surface of the latching portion being generally cylindrical, the through hole extending from the first end to the second end, the cap defining an opening at the center thereof, and the diameter of the opening being smaller than that of the through hole;
- and
- a lens received in the barrel at the latching portion, an outer surface of the lens being generally cylindrical;
- wherein a transverse cross-section of one of the surface of the latching portion and the outer surface of the lens is a curved bulge, and a transverse cross-section of the other of the surface of the latching portion and the outer surface of the lens defines a curved recess matching the curved bulge, such that the lens is latched in the latching portion.
