Camera module having a lens assembly with at least one flange projecting therefrom and assembling method

A method of assembling a camera module including a housing, a lens assembly, an electronics carrier, and an image sensor, the method comprising:

• providing a lens assembly including a lens body defining an optical axis, the lens assembly comprises at least one first flange projecting radially outwards from the lens assembly perpendicular to the optical axis;
• attaching the lens assembly and the electronics carrier to each other so as to establish an optical communication between the lens assembly and an image sensor;
• and
• attaching the lens assembly to the housing by;
• providing a first adhesive on at least one of an inner surface of the housing and the at least one first flange;
• and
• moving the lens assembly and the housing towards each other such that the at least one first flange of the lens assembly abuts the inner surface of the housing so as to permanently attach the lens assembly and the housing to each other by the first adhesive,
• wherein a sub-assembly formed by the lens assembly and the electronics carrier is fitted to the housing once the lens assembly and the electronics carrier have been attached to each other, the at least one first flange of the lens assembly acts as a stopper for the sub-assembly until abutting a housing flange of the housing.

A camera module comprising:

• a housing having an inner surface;
• a lens assembly comprising a lens body with one or more lenses arranged at least partially within the housing and defining an optical axis;
• an electronics carrier;
• and
• an image sensor arranged on a surface of the electronics carrier in optical communication with the lens assembly;
• at least one positioning portion to attach the lens assembly and the electronics carrier to each other;
• and
• at least one first flange projecting radially outwards from the lens assembly perpendicular to the optical axis, with the at least one first flange and the inner surface of the housing capable of being attached to each other such that the at least one first flange acts as a stopper when moving the lens assembly into an interior space of the housing,
• wherein a sub-assembly formed by the lens assembly and the electronics carrier is fitted to the housing once the lens assembly and the electronics carrier have been attached to each other, the at least one first flange of the lens assembly acts as a stopper for the sub-assembly until abutting a housing flange of the housing.
