[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] The following is for reference. Figure 1 and Figure 2 This invention describes an adjustment limiting structure for a car rearview mirror according to an embodiment of the present invention.

[0023] like Figure 1 and Figure 2 As shown, the adjustment and limiting structure for a car rearview mirror according to an embodiment of the present invention includes a mirror body 100, a base 200, a limiting base plate 300, and a limiting sleeve 400.

[0024] The mirror body 100 can be rotated to adjust its angle; the limiting plate 300 is connected to the upper side of the bottom wall of the mirror body 100, and a movable limiting ring 310 is provided on the lower side of the limiting plate 300; a connecting post 210 is provided on the upper side of the base 200; the limiting sleeve 400 includes an inner mounting ring 410 and an outer ring 420, the inner mounting ring 410 is fitted onto the outer side wall of the connecting post 210, the outer ring 420 is located outside the inner mounting ring 410, and an annular limiting groove 430 with an upper opening is formed between the inner side wall of the outer ring 420 and the outer side wall of the inner mounting ring 410, the lower end of the movable limiting ring 310 extends into the annular limiting groove 430, and the movable limiting ring 310 can abut against the side wall of the annular limiting groove 430 to limit the rotation range of the mirror body 100.

[0025] For example, such as Figure 1 and Figure 2 As shown, the mirror body 100 can rotate to adjust its angle; that is, the mirror body 100 can rotate vertically around the vertical adjustment axis and horizontally around the horizontal adjustment axis. The vertical adjustment axis extends in the left-right direction, and the horizontal adjustment axis extends in the front-back direction. The intersection of the vertical and horizontal adjustment axes is at the center of the sphere. The limiting plate 300 is connected to the upper side of the bottom wall of the mirror body 100, meaning that the limiting plate 300 also adjusts synchronously with the mirror body 100. A movable limiting ring 310 is provided on the lower side of the limiting plate 300. The mirror body 100 achieves 360° omnidirectional swing angle adjustment by coordinating its vertical rotation around the vertical adjustment axis and its horizontal rotation around the horizontal adjustment axis.

[0026] The base 200 is relatively fixed, and a connecting post 210 is provided on the upper side of the base 200. The limiting sleeve 400 includes an inner mounting ring 410 and an outer ring 420. The outer ring 420 is located outside the inner mounting ring 410, that is, the limiting sleeve 400 is also relatively fixed on the base 200. An annular limiting groove 430 with an upper opening is formed between the inner side wall of the outer ring 420 and the outer side wall of the inner mounting ring 410. The lower end of the movable limiting ring 310 extends into the annular limiting groove 430. The movable limiting ring 310 can abut against the side wall of the annular limiting groove 430 to limit the rotation range of the mirror body 100.

[0027] In actual operation, the mirror body 100 can rotate in multiple directions on the base 200 to adjust the angle. This rotation process is limited by the cooperation of the limiting plate 300 and the limiting sleeve 400.

[0028] Reference Figure 3 , Figure 4 The movable limiting ring 310 of the limiting base plate 300 extends into the annular limiting groove 430 of the limiting sleeve 400. In this way, during the angle adjustment process of the mirror body 100, the movable limiting ring 310 can abut against the inner wall of the annular limiting groove 430 at a predetermined angle position, which is equivalent to limiting the rotation range of the mirror body 100.

[0029] For example, refer to Figure 5 During the up-and-down swinging of the mirror body 100, when the mirror body 100 swings to its limit angle, the annular limiting groove 430 will lock the movable limiting ring 310, preventing the mirror body 100 from swinging further. Similarly, when the mirror body 100 swings in other directions to adjust its angle, the annular design of the movable limiting ring 310, in conjunction with the annular design of the annular limiting groove 430, allows the annular limiting groove 430 to restrict the position of the corresponding movable limiting ring 310 in all 360° directions, which is sufficient to ensure that the mirror body 100 can achieve limiting in all directions when adjusting its angle.

[0030] Because the limiting sleeve 400 can be directly fitted onto the connecting post 210, its assembly is simple and convenient. Furthermore, since the movable limiting ring 310 extends downwards from the underside of the mirror body 100, and the annular limiting groove 430 on the base 200 opens upwards, the movable limiting ring 310 of the limiting base plate 300 and the annular limiting groove 430 of the limiting sleeve 400 can be easily aligned during mirror body 100 installation. This makes the installation process of the mirror body 100 on the base 200 much easier.

[0031] In some embodiments of this utility model, reference is made to Figure 4 , Figure 6 The lower end of the inner wall of the movable limiting ring 310 has a limiting ring support surface 311, which can abut against the outer wall of the inner mounting ring 410. That is, when the mirror body 100 swings to its limit angle, the limiting ring support surface 311 of the movable limiting ring 310 will abut against the outer wall of the inner mounting ring 410 in the annular limiting groove 430, preventing the mirror body 100 from continuing to swing. This can achieve a more stable limiting effect on the mirror body 100.

[0032] In some embodiments of this utility model, reference is made to Figure 4 , Figure 7 A sealing rubber ring 500 is provided at the upper end of the outer ring 420. The sealing rubber ring 500 can seal the gap between the outer wall of the movable limiting ring 310 and the inner wall of the outer ring 420. This can prevent foreign objects from entering the mirror body 100 and the base 200 through the gap between the movable limiting ring 310 and the outer ring 420, and can also improve the quietness when the mirror body 100 moves.

[0033] In some embodiments of this utility model, the outer wall of the movable limiting ring 310 has a convex arc-shaped surface 312, and the upper end of the sealing rubber ring 500 has a sealing rubber ring protrusion 510, with the convex arc-shaped surface 312 contacting the sealing rubber ring protrusion 510. This improves the tightness of the fit between the sealing rubber ring 500 and the movable limiting ring 310, thereby improving the sealing effect of the sealing rubber ring 500.

[0034] In some embodiments of this utility model, the sealing ring 500 has a sealing ring welding end 520 on its lower side. The sealing ring welding end 520 of the sealing ring 500 and the upper end of the outer ring 420 can be connected by welding, making the sealing ring 500 more stable.

[0035] A rearview mirror according to other embodiments of the present invention includes an adjustment and limiting structure for a rearview mirror according to the first aspect embodiment of the present invention described above. An integrated mechanism 600 is provided within the mirror body 100. The integrated mechanism 600 includes a fixed end 610 and a movable end 620. The fixed end 610 is connected to the upper end of a connecting post 210, and the movable end 620 is connected to the upper side of a limiting base plate 300. The fixed end 610 of the integrated mechanism 600 is relatively fixed, while the movable end 620 can rotate at multiple angles to adjust its angle.

[0036] According to the embodiments of the present invention, the rearview mirror of the car uses the above-mentioned adjustment and limiting structure applied to the rearview mirror, which reduces the number of related components of the rearview mirror, facilitates the simplified assembly design of the rearview mirror, and improves the stability of the rearview mirror when adjusting the angle, thereby enhancing the user experience.

[0037] In some embodiments of this utility model, reference is made to Figure 9 The connecting post 210 has a bottom opening 211 on its lower side, through which screws can extend into the connecting post 210. The upper end of the connecting post 210 has a connecting post end plate 212, which is connected to the lower side of the movement fixing end 610 by screws. Thus, the screws extend from the bottom opening 211 into the connecting post 210 and connect the connecting post end plate 212 to the movement fixing end 610 of the integrated movement 600, thereby achieving a fixed connection between the movement fixing end 610 of the integrated movement 600 and the connecting post 210 on the base 200.

[0038] In some embodiments of this utility model, reference is made to Figure 8 , Figure 9 The mechanism fixing end 610 has a through-hole 611 in the middle, and the connecting post end plate 212 has an end plate through-hole 213. The lower end of the mechanism through-hole 611 is connected to the upper end of the end plate through-hole 213. In this way, the wires on the vehicle body can pass through the base 200 and then pass through the end plate through-hole 213 and the mechanism through-hole 611 in sequence to enter the mirror body 100, realizing power supply and signal transmission.

[0039] In some embodiments of this utility model, reference is made to Figure 7 , Figure 9The limiting sleeve 400 has a bottom retaining clip 440 on its lower side, and a bottom retaining clip groove 441 is formed on the lower side of the bottom retaining clip 440. The lower side of the outer wall of the connecting column 210 has a limiting sleeve fixing plug 214, and the upper end of the limiting sleeve fixing plug 214 is inserted into the bottom retaining clip groove 441. This makes the fixing between the limiting sleeve 400 and the connecting column 210 more secure, especially preventing the limiting sleeve 400 from shifting or misaligning on the connecting column 210.

[0040] In some embodiments of this utility model, a base upper cover 220 is provided on the upper side of the base 200, and the base upper cover 220 has a base upper cover through hole 221, through which the connecting post 210 extends upward. A sealing rubber ring 500 is provided at the upper end of the outer ring 420, and the outer wall of the sealing rubber ring 500 can seal the gap between the outer wall of the movable limiting ring 310 and the hole wall of the base upper cover through hole 221.

[0041] The base cover 220 is installed on the base 200 as a top cover structure. The base cover through hole 221 of the base cover 220 facilitates the insertion and connection of the connecting column 210 or other components. The sealing rubber ring 500 seals the gap between the movable limiting ring 310 and the base cover through hole 221 to prevent foreign objects from entering the base 200.

[0042] In some embodiments of this utility model, reference is made to Figure 8 A bottom through hole 110 is provided on the lower side of the mirror body 100, and a bottom retaining ring 111 is provided on the upper side of the hole wall of the bottom through hole 110. A bottom retaining ring 330 is provided on the lower side of the limiting substrate 300, and a movable limiting ring 310 is located inside the bottom retaining ring 330. The upper end of the bottom retaining ring 111 locks the lower end of the bottom retaining ring 330, making the limiting substrate 300 more stable within the mirror body 100.

[0043] In some embodiments of this utility model, an outer ring insertion hole 421 is provided on the outer ring 420, and an upper protective cover through hole 222 is provided on the hole wall of the upper protective cover through hole 221.
