Described in the second eyeglass 22 be arranged in the image side of first eyeglass 21, the lens assembly 100 further includes anti-dazzling screen 3, described
Anti-dazzling screen 3 includes being folded in horizontal part 31 between first eyeglass 21 and second eyeglass 22 and from the horizontal part
31 one end far from the optical axis OO ' is perpendicular to the first vertical portion 321 of object lateral bending folding extension and to image side bending extension second
Straight portion 322, the horizontal part 31 are hollow annular structure, and first vertical portion 321 is folded in the first eyeglass 21 and second
Between wall 12, second vertical portion 322 is folded between the second eyeglass 22 and the second barrel 12.
The utility model embodiment in terms of existing technologies, passes through design anti-dazzling screen 3, the horizontal part of anti-dazzling screen 3
31 are clamped between the first eyeglass 21 and the second eyeglass 22, and the first vertical portion 321 of anti-dazzling screen 3 is clamped in the first eyeglass 21 and
Between two barrels 12, the second vertical portion 322 of anti-dazzling screen 3 is clamped between the second eyeglass 22 and the second barrel 12, to make screening
The first vertical portion 321 and the second vertical portion 322 of mating plate 3 are born against on 1 inner wall of lens barrel, and the horizontal part 31 of anti-dazzling screen 3 is by first
Eyeglass 21 and the second eyeglass 22 are fixed, and since anti-dazzling screen 3 is simple in structure, are easier for the opposite structure for adjusting lens barrel 1, institute
With design that can be more flexible, in the case where ensureing the first eyeglass 21 and the second 22 concentricity of eyeglass, by adjusting anti-dazzling screen 3
Structure can improve the degree of freedom of the first eyeglass 21 and the second eyeglass 22, using the eyeglass of different curvature and path length, improve camera lens
The optical property of component 100 improves the image quality of lens assembly 100.
In present embodiment, the horizontal part 31, the first vertical portion 321 and the second vertical portion 322 are structure as a whole, by
In horizontal part 31 and the first vertical portion 321 and the second vertical portion 322 be an entirety, the when to make assembling lens assembly 100
One anti-dazzling screen 3 can one-time fix on 1 inner wall of lens barrel, and assembling process is simple.
In present embodiment, the horizontal part 31 and optical axis OO ' weights are straight.Since horizontal part 31 is clamped in the first eyeglass
21 and second between eyeglass 22, play corrective action, in lens assembly to the position of first eyeglass, 21 and second eyeglass 22
100 in the case of symmetric design, and horizontal part 31 is vertical with optical axis OO ' can be ensured in the first eyeglass 21 and the second eyeglass 22
Mandrel is overlapped with optical axis OO ', to ensure that the first eyeglass 21 and the second eyeglass 22 have preferable concentricity, reaches lens assembly
100 design requirement.
In present embodiment, the first vertical portion 321 and the second vertical portion 322 are parallel with the optical axis OO '.Due to the first mirror
Piece 21 is born against on the first vertical portion 321, and the second eyeglass 22 is born against on the second vertical portion 322, the first vertical portion 321 and second
Is played to the position of the first eyeglass 21 and 22, the second mirror by corrective action, the first vertical portion 321 and the second vertical portion for vertical portion 322
322 it is parallel with the optical axis OO ' may further ensure that the first eyeglass 21 and the second eyeglass 22 have preferable concentricity, reach
The design requirement of lens assembly 100.
