When the camera module is installed, the sliding groove at the bottom of the camera module can be aligned to the boss at the top of the installation support, and then the camera module slides into the installation support from front to back along the boss.

Wherein, in order to prevent the camera module from sliding off the mounting bracket, the mounting bracket can be provided with an elastic arm hook which is positioned between the bosses and close to the limit position for mounting the camera module. Like this, when camera module slided elastic arm pothook department along the boss from the past backward for elastic deformation takes place downwards for the elastic arm pothook, after the camera module continued to slide and crossed the elastic arm pothook, the elastic arm pothook upwards recovered the original state and hooked camera module and fixed, makes camera module can not slide forward automatically and leave the installing support.

When the user dismantles the camera module, can press the elastic arm pothook, make it take place elastic deformation downwards, then push out the camera module can forward.

Further, the assembly method 200 may further include the steps of:

step S4: the expansion module is removably mounted within the cavity as shown in fig. 6D.

Wherein the base may include a cavity for mounting the expansion module. When the expansion module is installed, the expansion module can be slid into the cavity in parallel. Illustratively, a cavity mechanical retention structure, such as a plurality of ribs, may be provided in the cavity at appropriate locations to assist in easily mounting and retaining the expansion module in the proper position.

Illustratively, the expansion module and the cavity may each include screw holes, and the expansion module may be screwed into the cavity after the expansion module is installed in place.

Step S5: the image transmission device is arranged with wires for connecting at least two of the camera module, the image transmission module, or the expansion module, as shown in fig. 6E and 6F.

The assembling process of the image transmission apparatus is thus completed, wherein the mounting sequence of steps S1-S5 is merely exemplary and not limiting. For example, the order of steps S1, S2, S3, and S4 may be arbitrarily interchanged, and other orders of steps than those shown herein are also within the scope of the present invention.
