[0032] Further, see Figure 1The adjustable limit structure of the utility model includes a base 100 and a rearview mirror body 200. Figure 2 The automobile rearview mirror of the utility model is connected to the automobile through the base 100. Figure 3 The rearview mirror body 200 is used as the lens structure of the automobile rearview mirror of the utility model, and the rearview mirror body 200 can be adjusted according to the needs. Figure 2 , Figure 3 A connecting column 110 is provided on the base 100, a rearview mirror through hole 210 is provided on the lower side of the rearview mirror body 200, and the connecting column 110 extends into the rearview mirror body 200 from the rearview mirror through hole 210. A control motor 600 is provided on the connecting column 110 for controlling the rearview mirror body 200 to adjust the angle, wherein the structure and working principle of the control motor 600 can refer to other automotive rearview mirrors in the prior art.

[0033] Further, refer to Figure 3 The connecting column 110 is provided with a connecting column limiting ring 310, and the connecting column limiting ring 310 forms a ring-shaped structure. The connecting column limiting ring 310 is located in the rearview mirror body 200, that is, the connecting column limiting ring 310 is equivalent to the connecting column 110 being fixed.

[0034] Further, refer to Figure 2 A motor connecting frame 500 is provided in the rearview mirror body 200 , and the control motor 600 is connected to the rearview mirror body 200 through the motor connecting frame 500 , that is, the motor connecting frame 500 moves with the rearview mirror body 200 .

[0035] Furthermore, a connecting frame through hole 521 is provided at the lower side of the motor connecting frame 500, and the connecting column 110 passes through the connecting frame through hole 521 to connect with the control motor 600. A connecting frame limiting groove 522 is provided outside the connecting frame through hole 521, and the connecting frame limiting groove 522 surrounds the connecting frame through hole 521, so that the rearview mirror body 200 also forms a ring-shaped structure.

[0036] In actual work, refer to Figure 7 The rearview mirror body 200 of the automobile rearview mirror of the utility model is adjusted in angle by controlling the motor 600. When the rearview mirror body 200 is in motion, the connection frame limit groove 522 of the rearview mirror body 200 also moves accordingly. Once the rearview mirror body 200 moves to the limit position in a certain direction, the corresponding direction of the connection frame limit groove 522 will hit the corresponding direction position of the connection column limit ring 310 on the connection column 110 to achieve a limiting effect. The ring-shaped connection column limit ring 310 cooperates with the ring-shaped connection frame limit groove 522 to achieve a limiting effect on the arbitrary flip adjustment angle range of the rearview mirror body 200.
