[0033] Such as Figure 1 、 Figure 2As shown in the figure, a rearview mirror mounting structure includes a rearview mirror assembly 3, a mounting column 1, and an adjustment mechanism 2. The bottom of the mounting column 1 is fixed to the vehicle body. The rearview mirror assembly 3 is fixed to the upper part of the mounting column 1 through the adjustment mechanism 2 to achieve multi-degree-of-freedom adjustment. The adjustment mechanism 2 includes a first adjustment component and a second adjustment component. The front part of the first adjustment component is connected to the rear side of the rearview mirror assembly 3, and the connection between the two is formed by at least one vertically arranged and adjustable hinge point for realizing the left-right rotation adjustment of the rearview mirror assembly 3. On the one hand, the second adjustment component is rotatably connected to the upper part of the mounting column 1 to achieve the up-down rotation and left-right movement adjustment of the rearview mirror assembly 3. On the other hand, it is detachably connected to the rear side of the first adjustment component, and there are multiple vertically arranged fixing points on the rear side of the first adjustment component for realizing the up-down movement adjustment of the rearview mirror assembly 3.

[0034] The following further explains the above-mentioned first adjustment component.

[0035] As shown in Figure 1 , Figure 2 , Figure 3 the figure, the first adjustment component is a special-shaped bent plate 6, which includes a vertical mounting surface 14 and at least two vertically arranged parallel mounting surfaces 13. There is a coaxial mounting hole I on each of the at least two parallel mounting surfaces 13. Multiple mounting plates 15 corresponding to the parallel mounting surfaces 13 one by one are fixed on the rear side of the rearview mirror assembly 3. There is a coaxial mounting hole II on each of the at least two mounting plates 15. After assembling fasteners in each group of aligned mounting holes I and II, an adjustable hinge point is formed.

[0036] It should be noted that in the embodiment in the attached figure, the special-shaped bent plate 6 has three vertically arranged parallel mounting surfaces 13, and three mounting plates 15 are fixed on the rear side of the rearview mirror assembly 3. The rearview mirror assembly 3 and the special-shaped bent plate 6 adopt a three-point coaxial mounting form to realize the left-right rotation adjustment. Of course, in actual design, it is not limited to the above three parallel mounting surfaces and three mounting plates, and can also be designed as two parallel mounting surfaces and two mounting plates or four parallel mounting surfaces and four mounting plates.

[0037] A further solution, as shown in Figure 1 , Figure 2 the figure, the fastener is a bolt and at least one nut. The bolt vertically penetrates into the aligned mounting holes I and II, and is fixed by screwing at least one nut onto the bolt. After loosening the nut, the rearview mirror assembly 3 can rotate left and right around the bolt as the rotation axis. After rotating to the preset angle, the nut is tightened to fix the rearview mirror assembly 3 on the special-shaped bent plate 6.

[0038] A further solution, as shown in Figure 1 , Figure 2As shown, multiple groups of assembly holes arranged vertically are formed on the vertical installation surface 14. Each group of assembly holes serves as a fixed point. After the adjustment component two matches the assembly holes at different positions, the up-and-down movement adjustment of the rearview mirror assembly 3 is realized.

A semi-circular groove is formed on each of the opposite sides of the two card slots 7, and a connection hole is formed at the upper and lower positions of the semi-circular groove; one set of two card slots 7 is clamped on the side mounting rod 9 of the mounting column 1 in a relative manner and fastened together with the special-shaped bending plate 6 through fasteners.

[0042] A further solution is as Figure 1 、 Figure 2 shown. The fasteners are two bolts and multiple nuts. The two bolts are respectively inserted into the connection holes of the two semi-circular grooves aligned up and down and the assembly holes of the special-shaped bending plate 6, and are fixed by screwing at least one nut onto the bolts; after loosening the nuts, the rearview mirror assembly 3 and the special-shaped bending plate 6 jointly rotate up and down and move left and right around the side mounting rod 9 through the two card slots 7. After rotating to the preset angle and moving to the preset position, the nuts are tightened to fix the rearview mirror assembly 3 and the special-shaped bending plate 6 on the side mounting rod 9.

[0043] It should be noted that two nuts can be screwed onto the bolt simultaneously for fixation. One nut is used for tightening, and the other bolt is used for locking. Of course, the fasteners are not limited to the above two bolts and multiple nuts, and can also be a U-shaped bolt and multiple nuts. The U-shaped bolt is simultaneously inserted into the connection holes of the two semi-circular grooves aligned up and down and the assembly holes of the adjustment component one, and is fixed by screwing at least two nuts onto the U-shaped bolt.

[0044] The following further explains the above-mentioned mounting column.

[0045] As Figure 1 、 Figure 2 shown, the mounting column 1 adopts a cross-fixed mounting structure form and is fixed on the upper plane and the side vertical surface of the vehicle body platform through the bottom mounting seat 4 and the side mounting seat 5 respectively.

[0046] A further solution is as Figure 1 、 Figure 2As shown in the figure, the mounting column 1 includes a support column 8, a side mounting rod 9, a front pull rod 10, and a connecting component 16; a bottom mounting seat 4 is fixed to the bottom surface of the support column 8; the side mounting rod 9 is of a special-shaped bending structure, and its two free ends are fixed to the side surface of the support column 8, forming a closed structure with the support column 8; the front pull rod 10 is fixed between the support column 8 and the bottom mounting seat 4, thereby forming a triangular support structure; the upper part of the connecting component 16 is fixed to the lower part of the support column 8, and the side mounting seat 5 is fixed to the lower part of the connecting component 16.

[0047] In a further solution, as Figure 1 、 Figure 2 shown, the bottom mounting seat 4 is a right-angle plate, which is respectively welded to the bottom surface and side surface of the support column 8 and the bottom surface and side surface of the front pull rod 10; the connecting component 16 is composed of a pair of opposed connecting plates. The upper parts of the connecting plates are welded to the support column 8 and the side mounting rod 9 and then extend vertically downward. During the extension process, they are welded to the bottom mounting seat 4, and the side mounting seat 5 is welded to the part of the connecting plate extending from the support column 8.

[0048] In a further solution, as Figure 1 、 Figure 2 shown, at least one triangular rib plate I 11 is welded between the bottom mounting seat 4 and the support column 8; at least one triangular rib plate II 12 is welded between the side mounting rod 9 and the support column 8 to ensure the stability of the side mounting rod 9.
