Fig. 1 is an exploded perspective view of a mirror assembly according to an embodiment of the present utility model, and fig. 2 is a partially cut-away perspective view of a mirror assembly according to an embodiment of the present utility model. Referring now to FIGS. 1-2 in combination, the present utility model provides a mirror assembly 10 comprising a mirror angle adjustment mechanism 100 and a mirror 200, the mirror 200 being mounted to the mirror angle adjustment mechanism 100. The mirror angle adjustment mechanism 100 includes a mounting bracket 110, an adjustment base 120, an elastic connection assembly 130, and three adjustment members 140. The adjusting seat 120 is elastically connected with the mounting frame 110 through the elastic connection assembly 130, and the adjusting seat 120 has an adjusting surface 121, the adjusting surface 121 faces the mounting frame 110, and three adjusting members 140 are adapted to pass through the mounting frame 110 and abut against the adjusting surface 121 of the adjusting seat 120.

In this embodiment, the adjusting seat 120 further has a receiving portion 122 and a through hole 123, and the elastic connection assembly 130 includes a screw 131, a nut 132 and a spring 133, wherein the nut 132 is a ball nut and is disposed in the receiving portion 122 of the adjusting seat 120. Screw 131 is adapted to pass through mounting bracket 110 and through hole 123 and is connected to nut 132. It should be noted that the screw 131 is partially located on the side of the mounting frame 110 near the nut 132, partially located on the side of the mounting frame away from the nut 132, and the spring 133 is wrapped around the portion of the screw 131 located on the side of the mounting frame 110 away from the nut 132 (left side of the mounting frame 110 as shown in fig. 1).

Specifically, one end of the spring 133 abuts against the nut 134 of the screw 131, the other end abuts against the surface of the mounting frame 110 far away from the nut 132, and the spring 133 is always kept in a compressed state, so that the screw 131 and the mounting frame 110 have a tendency to be far away from each other. It will be appreciated that one end of the screw 131 is connected to the nut 132 and the nut 132 is located on the adjustment seat 120, so that the adjustment seat 120 always has a tendency to approach the mounting bracket 110 under the action of the spring 133. And in order to prevent the nut 132 from being removed from the adjustment seat 120, the diameter of the nut 132 is greater than the diameter of the through hole 123.

Further, the three adjustment members 140 are adapted to pass through the mounting frame 110 and respectively abut against the adjustment surface 121 of the adjustment seat 120, and the three adjustment members 140 are movable in a direction perpendicular to the mounting frame 110, thereby applying a force to the adjustment seat 120 away from the mounting frame 110. In the present embodiment, three adjusting members 140 are disposed around the screw 131 in the elastic connection assembly 130, it is understood that the elastic connection assembly 130 always keeps the adjusting seat 120 close to the mounting frame 110, and the three adjusting members 140 push against the adjusting seat 120 away from the mounting frame 110, so that the inclination angle of the adjusting seat 120 relative to the mounting frame 110 can be changed by moving the positions of the three adjusting members 140.

In order to make the adjusting member 140 play a role in changing the inclination angle of the adjusting seat 120, and at the same time avoid damage to the adjusting surface 121, the top of the three adjusting members 140 contacting the adjusting surface 121 in this embodiment is rounded.

Furthermore, the mirror angle adjusting mechanism 100 provided in the present embodiment further includes a mirror base 150, the mirror base 150 is disposed on the adjusting base 120, and a portion of the mirror base 150 is located in the accommodating portion 122 of the adjusting base 120. Specifically, the lens holder 150 is screwed to the accommodating portion 122, and the distance between the lens holder and the accommodating portion can be adjusted by rotating the screw. The lens holder 150 further includes a recess 151, and in this embodiment, the ball nut 132 is partially disposed in the recess 151 of the lens holder 150. This arrangement reduces the axial space of the mirror angle adjustment mechanism 100 and allows the mirror mount 150 to smoothly rotate relative to the ball nut 132 as it tilts with respect to the adjustment mount 120.

The lens holder 150 in this embodiment further has a mounting portion 152 adapted to mount the reflecting mirror 200.

Fig. 3-4 are perspective assembly schematic views of a mirror assembly according to an embodiment of the utility model. In fig. 3, the three adjusting members 140 do not protrude from the mounting frame 110, i.e. the adjusting seat 120 is not far away from the mounting frame 110, and at this time, the adjusting surface 121 of the adjusting seat 120 is attached to the mounting frame 110, so that the inclination angle of the adjusting seat 120 cannot be adjusted. In fig. 4, all three adjusting members 140 protrude from the mounting frame 110, and a gap is formed between the adjusting surface 121 (not shown, refer to fig. 2) of the adjusting seat 120 and the mounting frame 110, so that when the protruding degrees of the three adjusting members 140 are consistent, the adjusting seat 120 will not incline and still remain parallel to the mounting frame 110; when the protruding degrees of the three adjusting members 140 are not consistent, the adjusting seat 120 cannot be parallel to the mounting frame 110, but an inclined angle is generated, so that the purpose of adjusting the angle of the reflecting mirror 200 is further achieved.

In other embodiments of the present utility model, the number of the adjusting members 140 may be more, and the present utility model is not limited herein.

Fig. 5-6 are perspective views of a mirror assembly according to another embodiment of the present utility model, in which the mirror assembly 10 includes four mirror angle adjustment mechanisms 100 (not shown in fig. 5 for angular reasons), four mirrors 200, and a base plate 300, the four mirrors 200 being mounted on the four mirror angle adjustment mechanisms 100, respectively. Wherein fig. 5 shows the front side of the mirror assembly 10, i.e. the mirror 200 side, and fig. 6 shows the back side of the mirror assembly 10. In other embodiments of the utility model, the mirror assembly 10 may include more or fewer mirror angle adjustment mechanisms 100 and mirrors 200, the specific number of which the utility model is not limited in this regard.
