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.

Embodiment Construction

[0028] use Figure 1 to Figure 4 The camera module 1 according to the embodiment of the present invention will be described.

[0029] Figure 1 to Figure 3 middle, figure 1 It is a perspective view showing the appearance of the camera module 1 of the embodiment of the present invention, figure 2 yes figure 1 A central longitudinal sectional view of the camera module 1 is shown, image 3 It is an exploded view showing only the first casing 2 and the second casing 3 .

[0030] The camera module 1 is mainly used to be mounted on the rear or the left and right sides of the body of an automobile (not shown), and is mainly used for grasping the situation of a blind spot viewed from the driver's seat of the automobile. In addition, the camera module 1 is attached to the rear part and the left and right side parts of the vehicle body, and the images obtained from the four camera modules 1 are processed and synthesized, and a type that displays an image overlooking the car from...

Abstract

A camera module with internal structural elements housed inside a housing space formed by joining two cases together achieves a sufficient joint strength between both cases even though the thickness of the case walls is reduced to make the outer shape smaller, as well as a size reduction of the camera module is enabled, when the two cases are joined together by ultrasonic welding. The joint surfaces where the two cases are joined together are inclined relative to a plane orthogonal to the optical axis direction of a lens unit housed inside the camera module. Thereby, the area of joint surfaces is increased as compared with the case where the joint surfaces are parallel to the plane orthogonal. Also, since interference between a horn for applying ultrasonic waves during ultrasonic welding and the external connection part is avoided, the camera module can be made smaller.

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...
