camera module

Abstract

The present invention provides a camera module. In a camera module in which an internal structure is accommodated in an accommodating space formed by joining two housings, both housings can be made smaller even when the thickness of the wall portion of the housing is reduced and the outer shape is reduced. The joint strength between them is sufficient, and when the two cases are joined by ultrasonic welding, the camera module can be downsized even when the external connection mechanism is protrudingly provided from the side wall surface of the case. The bonding surface where the two housings are bonded is inclined relative to a plane perpendicular to the optical axis direction of the lens unit accommodated inside the camera module, so that the bonding surface is parallel to the case where the bonding surface is parallel to the plane orthogonal to the optical axis direction. The area of ​​the camera module is enlarged, so that sufficient bonding strength can be obtained, and the resonator for applying ultrasonic waves during ultrasonic welding can be avoided from interfering with the external connection mechanism, thereby enabling miniaturization of the camera module.

Description

technical field [0001] The present invention relates to a camera module, and more specifically relates to a camera module in which internal structures are accommodated in an accommodation space formed by joining two casings. Background technique [0002] In recent years, for the purpose of grasping the situation of the range that is a blind spot viewed from the driver's seat of a car, so-called image monitoring systems are widely used. to the image. In addition, image monitoring systems of the type in which a total of four imaging mechanisms are mounted on the rear, front, and left and right sides of a car, and images obtained from each imaging mechanism are processed and synthesized, can be simulated. Displays an image looking down on the car from directly above. [0003] A camera module is widely used as an imaging means of such an image monitoring system. An example of a camera module is disclosed in Reference 1 (see Figure 5 ). The camera module disclosed in Referen...

Problems solved by technology

However, if the thickness of the base portion 200 is reduced, the area of ​​the bonding surface where the front-side base portion 200a and the rear-side base portion 200b are opposed and bonded decreases, making it difficult to obtain sufficient bonding strength.
