Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is the U.S. national stage application of International Patent Application No. PCT/KR2022/012676, filed Aug. 24, 2022, which claims the benefit under 35 U.S.C. § 119 of Korean Application No. 10-2021-0114196, filed Aug. 27, 2021, the disclosures of each of which are incorporated herein by reference in their entirety. TECHNICAL FIELD The present embodiment relates to a camera module. More specifically, the present invention relates to a camera module that minimizes the reduction of component mounting space in a multiple substrate stack structure. BACKGROUND ART In general, since camera modules are manufactured in small sizes and are applied to various IT devices such as camera phones, PDAs, smartphones, and other portable mobile communication devices, in recent years, the release of devices equipped with small camera modules is gradually increasing according to various preferences of consumers.

For such examples, there are camera modules being used in front and rear surveillance cameras, black boxes, and the like. In addition, as demands for driver convenience and safety increase in the automobile industry, a variety of new technologies are being applied. In particular, technology using cameras is being actively applied by converging with software technology. Meanwhile, recently, a structure is being studied in which a plurality of substrates being disposed inside the camera module of vehicle camera is provided for lamination. However, when fixing a plurality of substrates using screws, the area of the substrates where the screws are coupled becomes an unusable area, which causes a problem in that component mounting space is reduced. In addition, there is a problem that the time required for the manufacturing process increases due to the screw fastening operation. In addition, there is a problem in that there is a possibility of substrate bending occurring due to excessive torque when fastening screws. DETAILED DESCRIPTION OF THE INVENTION Technical Subject The present embodiment is intended to provide a camera module that minimizes the reduction of component mounting space in a multiple substrate stack structure.
