Embodiment approach
[0049] According to one embodiment of the present invention, the boss and the upper casing 1 are separate components, and are fixed by bonding or welding. According to the second embodiment of the present invention, the boss and the upper casing 1 can be integrally formed.
[0050] combine Figure 9-Figure 11 As shown, the black circle in the figure represents the welding position point. According to the concept of the present invention, the boss and the limiting groove can be welded and fixed on the side, or one end of the boss facing the lower casing 2 is welded and fixed to the limiting groove, or one end of the boss facing the lower casing 2 is welded and fixed to the limiting groove, Simultaneously, the boss and the side of the limiting slot are welded and fixed. Specifically, it can be selected according to actual needs.
[0051] Such as Figure 12 As shown, according to the second embodiment of the present invention, the first welded portion 31 and the second welded...

The invention relates to a camera shooting module shell structure and a camera shooting module comprising the camera shooting module shell structure. The camera shooting module shell structure comprises an upper shell (1) and a lower shell (2), the upper shell (1) and the lower shell (2) are at least partially welded and fixedly connected, and a welding structure (3) is formed at the local welding position; a sealing ring (4) is further arranged between the upper shell (1) and the lower shell (2), and the sealing ring (4) is located on the inner side of the welding structure (3). The camera module shell structure has a large internal space and is good in connection firmness, and the loosening risk existing in screw locking can be effectively avoided. On the other hand, the sealing requirement is met through the sealing ring and the local welding mode, and compared with the whole-circle welding sealing scheme in the prior art, the welding quality requirement is low, the welding line is short, the welding operation difficulty is low, and the product yield is increased.
Description
technical field [0001] The invention relates to the technical field of optical system and device design, in particular to a housing structure of a camera module and a camera module. Background technique [0002] With the rapid development of the automobile industry, the application technology of on-board cameras is becoming more and more mature. Cars with cameras as advanced driving assistance systems have high requirements for the sealing of camera modules, and at the same time, the requirements for miniaturization of camera modules are also getting higher and higher. For some modules with high heat dissipation requirements, metal shells are used. At present, metal shells are usually fixed with sealing rings and screw locks, or by welding the entire ring of the shell for sealing. [0003] The above-mentioned fixing method mainly has the following defects: in the case of a certain internal space of the housing, the fixing method of screw locking has the problem of space occ...
