[0018] The technical scheme in the embodiment of the present invention will be described below in conjunction with the accompanying drawings in the embodiment of the present invention:

[0019] like Figure 1-4As shown, a multifunctional streaming media rearview mirror system is mainly composed of a rearview mirror body 1, a main control board, a display screen 2 and a buzzer; wherein the rearview mirror body 1 includes a camera 11 and a bracket 12, the camera 11 includes a variable aperture 13, a lens group 14 and an image sensor 15 arranged in sequence, the variable aperture 13 is electrically connected to the main control board, the camera 11 is connected to the vehicle through the bracket 12, the main control board is placed in the engine compartment, and image information is transmitted through GMSL (Gigabit Multimedia Serial Link).

[0020] There are two display screens 2, which are respectively embedded on the left and right sides of the door panel 3 inside the vehicle. When the vehicle turns left / right, the left / right display screens 2 automatically switch their fields of view, allowing the camera to capture more environmental information.

[0021] A cavity 16 for mounting the camera 11 is provided on the bracket 12, and a light-transmitting hole 17 is provided on the outer wall of the cavity 16. A pair of reflectors 18 are provided between the light-transmitting hole 17 and the camera 11. The reflectors 18 are symmetrically arranged at the two outer ends of the camera 11 at an angle of 45°. The camera 11 is fixed by gluing, and a sealing ring is provided between the cavity 16 and the camera 11.
