The spherical end surface of the mirror foot 43 is rotatably connected to the ball socket 411 in the ball head seat 41 to flexibly adjust the viewing angle of the automobile interior rearview mirror assembly; the ball socket 411 structure of the present application is a well-known technology, specifically, it is a petal-shaped structure that is separated along the circumferential direction near the outer surface. The automobile interior rearview mirror assembly of the utility model has a compact structure, flexible operation, and a small overall space occupation, which can effectively avoid safety risks such as head collisions, and its mounting structure 4 has good reliability and stability, which can meet the performance requirements of long-term use.

[0033] The type of the lens element 1 of the present application is not strictly limited. In one embodiment, Figures 1 to 4As shown, the lens element 1 is an electrochromic rearview mirror lens element 1 (also referred to as an electro-optical element, or EC mirror). The electrochromic rearview mirror lens element 1 is a well-known technology in the art. As an example, the electrochromic rearview mirror lens element 1 technical solution described in the applicant's prior patent application (CN206421132U, CN208384316U or CN214299895U) can be selected; specifically, it can be formed by bonding a front transparent conductive glass and a rear conductive reflective glass by a sealant, and the sealant is arranged between the peripheral areas of the front glass and the rear glass along the circumferential direction to seal the front glass and the rear glass to each other and define a cavity; the electrochromic material is arranged in the cavity. The front transparent conductive glass is a glass substrate on which at least a transparent conductive functional film layer is plated, and the rear conductive reflective glass is a glass substrate on which at least a conductive reflective functional film layer is plated; the transparent conductive functional film layer and the conductive reflective functional film layer are in contact with the electrochromic material. The rear conductive reflective glass of the lens element 1 is also provided with two electrodes, and a 2P wiring harness (not shown) with a quick-connect connector is welded to the two electrodes and then electrically connected to the circuit board 7. The electrochromic rearview mirror lens element 1 undergoes a reversible change in color and optical properties under the control of the circuit board 7 at a low voltage of less than 1.5V, thereby achieving the anti-glare effect of the rearview mirror. Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, in the vehicle interior rearview mirror assembly in which the lens element 1 is an electrochromic rearview mirror lens element 1, the vehicle interior rearview mirror assembly further includes a circuit board 7.
