Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0020] Specifically, in this embodiment, by setting the DMS bracket structure to be rotatable in three axial directions, the setting of the DMS lens is more flexible, and 360° flexible adjustment can be realized according to the shooting requirements of different vehicle models and drivers of different heights to meet different needs.

[0021] In a specific embodiment, as Figure 2As shown, the base 1 includes a first mounting plate 11 and fixing seats 12 respectively arranged at both ends of the first mounting plate; the first mounting plate 11 is provided with a first through hole penetrating its thickness, and a first serrated structure is provided on one end face close to the first rotating member 2.

[0022] Specifically, the fixing seat 12 is provided with a mounting hole. In practice, when installing the DMS, the DMS is fixed in the vehicle by passing a screw through the mounting hole.

[0023] In a specific embodiment, as Figure 2 and Figure 3 shown, the first rotating member 2 includes a first rotating table 21 and a second mounting plate 22. The second mounting plate 22 is provided on one end face of the first rotating table 21 far from the first mounting plate 11; a second serrated structure is provided on one end face of the first rotating table 21 close to the first mounting plate 11. The first rotating table 21 and the first mounting plate 11 are meshed and connected through the second serrated structure and the first serrated structure, and are fixed by a first screw.

[0024] Specifically, the first serrated structure is arranged around the first through hole. A threaded hole is further provided on the end face of the first rotating table 21 provided with the second serrated structure, and the second serrated structure is arranged around the threaded hole. The first rotating table 21 and the first mounting plate 11 are meshed and connected through the second serrated structure and the first serrated structure, and then the first rotating member 2 and the base 1 are fixed by passing a first screw through the first through hole and the threaded hole in sequence. When it is necessary to adjust the first rotating member 2 to change the angle of the DMS lens, loosen the first screw and rotate the first rotating member 2 to the required angle. The alignment and locking connection through the serrated structure can prevent relative sliding between the first rotating member 2 and the base 1 and ensure the stability of the DMS lens.

[0025] In a specific embodiment, as Figure 3 and Figure 4 shown, the second mounting plate 22 is provided with a second through hole penetrating its thickness, and a third serrated structure is provided on one end face close to the second rotating member 3. A fourth serrated structure is provided on one end face of the second rotating member 3 close to the second mounting plate 22.

The end face of the second rotating member 3 provided with the fourth serrated structure is further provided with a threaded hole, and the fourth serrated structure is arranged around the threaded hole. After the second rotating member 3 and the second mounting plate 22 are meshed and connected through the fourth serrated structure and the third serrated structure, the second screw sequentially passes through the second through hole and the threaded hole to fix the second rotating member 3 and the second mounting plate 22. When it is necessary to change the angle of the DMS lens by adjusting the second rotating member 3, loosen the second screw, rotate the second rotating member 3 to the required angle, and the connection locked by the serrated structure can prevent relative sliding between the second rotating member 3 and the second mounting plate 22, ensuring the stability of the DMS lens.

[0027] In a specific embodiment, as Figure 4 shown, the second rotating member 3 is provided with a third through hole along a direction perpendicular to the axis of the first rotating member, and a fifth serrated structure is provided on the end face close to the DMS member 4. The DMS member 4 includes a DMS lens 41 and a sixth serrated structure 42.

[0028] Specifically, as Figure 1 and Figure 5 shown, in this embodiment, the sixth serrated structure 42 is provided, and the end face of the sixth serrated structure 42 close to the DMS lens 41 is protruded. The protrusion is an annular structure surrounding the fourth through hole. The end face of the DMS lens is provided with a groove matching the protrusion, and a threaded hole is provided in the middle of the groove. The DMS lens 41 and the sixth serrated structure 42 are clamped and matched through the protrusion and the groove. After the DMS lens 41 and the second rotating member 3 are meshed and connected through the sixth serrated structure and the fifth serrated structure, the third screw sequentially passes through the third through hole, the fourth through hole and the threaded hole to fix the second rotating member 3 and the DMS lens 41. When it is necessary to further adjust the angle of the DMS lens 41, loosen the third screw to rotate the sixth serrated structure, and drive the DMS lens to rotate to the required angle through the sixth serrated structure, thereby realizing angle adjustment.

[0029] Specifically, in this embodiment, a groove positioning mark is provided on the outer wall of each serrated structure. The groove positioning mark is used to determine the initial position of rotation, and it is convenient to assemble the first rotating member 2, the second rotating member 3 and the DMS member 4 according to the groove positioning mark.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention.
