The rotating arm 12 can rotate around the rotating shaft 11 through the driving of the folding motor assembly 14, that is, the rotating and folding function of the mirror housing assembly 13 is realized. The connection between the fixed arm 10 and the side of the vehicle body adopts the existing connection method.

[0037] One end of the rotating arm 12 has an assembly cavity 15 that penetrates the upper and lower surfaces of the rotating arm 12, and the other end is connected to the mirror housing assembly 13; in order to achieve the integrity of the rotating arm 12 and the folding motor assembly 14, the folding motor assembly 14 and the rotating shaft 11 are in the assembly cavity 15.

The folding shell 17 has a motor shell 19 for placing the motor, and a transmission shell 20 on one side of the motor shell 19 into which a transmission gear assembly is placed, and the rotating platform 18 is located below the transmission shell 20.

[0039] The lower end of the rotating shaft 11 is connected to the fixed platform 16, and the upper end of the rotating shaft 11 passes through the rotating platform 18 and the transmission housing 20 of the folding shell 17; a spring 21 is sleeved on the rotating shaft 11 above the transmission housing 20, and an upper limit member 22 is provided at the upper end of the rotating shaft 11. The upper end of the spring 21 is pressed by the upper limit member 22, and the lower end is pressed by the transmission housing 20 of the folding shell 17. Specifically, the lower end of the spring 21 is pressed against the transmission housing 20 of the folding shell 17. Therefore, through the arrangement of the spring 21, during the folding and rotating process, the pressure of the spring 21 on the transmission housing 20 increases the degree of fit between the rotating platform 18 and the fixed platform 16 during the rotation process. After the rotation is in place, the spring 21 can also give pressure to the rotating platform 18 to keep it in the corresponding position, so as to ensure the stability of the rearview mirror during the folding process and after folding and unfolding.
