Background

In recent years, with the rapid development of the mobile phone industry, customers have special requirements on the stray light of the mobile phone camera and the appearance of the lens cone ceiling. In order to achieve the appearance effect of the surface of the camera lens barrel being super-black, the reflectivity of the surface of the camera lens barrel to light needs to be reduced as much as possible, however, the lens barrel manufactured by the existing method for achieving the super-black surface of the lens barrel still has a certain reflectivity to light, the extinction effect is poor, and the true super-black effect is difficult to achieve.

Disclosure of Invention

In view of this, the embodiments of the present application provide an extinction structure having a good extinction effect.

In addition, the application also provides a lens barrel.

In addition, the application also provides an image capturing device.

In addition, this application still provides an electronic equipment.

The embodiment of the application provides an extinction structure, it includes:

a light-transmitting portion; and

the extinction part surrounds the light transmission part and at least comprises an extinction main body, a plurality of first sub extinction parts and a plurality of second sub extinction parts, and the extinction main body is provided with a first surface and a second surface which are arranged oppositely; the plurality of first sub-extinction portions are arranged on the first surface at intervals; the plurality of second sub extinction portions are arranged on the first surface at intervals, and the plurality of second sub extinction portions intersect with the plurality of first sub extinction portions.

The extinction structure comprises a light-transmitting portion and an extinction portion, wherein the extinction portion comprises an extinction main body, a plurality of first sub-extinction portions arranged on the extinction main body at intervals and a plurality of second sub-extinction portions arranged on the extinction main body at intervals, and the plurality of second sub-extinction portions are intersected with the plurality of first sub-extinction portions. Therefore, the area of direct reflection of the surface of the extinction part can be reduced, the number of times of reflection of light rays on the first sub-extinction parts and the second sub-extinction parts is increased, and the energy reflected by the light rays is reduced, so that the appearance effect of eliminating stray light and super-black surface is realized, and the good extinction effect is achieved.

Optionally, the plurality of first sub-extinction portions extend along a first direction, and the extending direction of the plurality of first sub-extinction portions is perpendicular to the arrangement direction of the plurality of first sub-extinction portions; the second sub-extinction portions extend along a second direction, and the extending direction of the plurality of second sub-extinction portions is perpendicular to the arrangement direction of the plurality of second sub-extinction portions; each of the first sub-extinction portions intersects with a plurality of second sub-extinction portions, each of the second sub-extinction portions intersects with a plurality of first sub-extinction portions, wherein the first direction intersects with the second direction. Thus, the extinction structure has a better extinction effect.

Optionally, a gap between two adjacent first sub-extinction portions ranges from 0.001mm to 0.03 mm.

Optionally, a gap between two adjacent second sub-extinction portions ranges from 0.001mm to 0.03 mm.

Alternatively, the sum of the numbers of the first sub extinction portion and the second sub extinction portion ranges from 30 to 200.

Optionally, an included angle between the first sub extinction portion and the second sub extinction portion is a right angle or an acute angle, and a half range of the included angle is 5 ° to 45 °. When one half of an included angle between the first sub extinction part and the second sub extinction part is smaller than 5 degrees, other parts of the extinction main body are easily cut off due to processing errors in the processing process, and the stray light effect is poor; when one half of an included angle between the first sub extinction part and the second sub extinction part is larger than 45 degrees, the area of a non-extinction area on the extinction main body is too large, and the extinction effect is poor.

Optionally, each of the plurality of first sub-extinction portions and the plurality of second sub-extinction portions is an extinction groove, and a depth of the extinction groove ranges from 0.05mm to 0.1 mm. When the depth of the extinction groove is less than 0.05mm, the reflection times of light rays in the extinction groove are less, the extinction effect is poor, and when the depth of the extinction groove is more than 0.1mm, the extinction groove is easy to deform in the demolding process, so that the extinction effect is influenced.

Optionally, the first sub extinction portion and the second sub extinction portion each have a first intersection line and a second intersection line intersecting the first surface, and a third intersection line farthest from the first surface; the first intersecting line and the third intersecting line are connected through at least one extinction surface which is sequentially connected; the second intersecting line and the third intersecting line are connected through at least one extinction surface which is sequentially connected, and the at least one extinction surface can be a plane or a curved surface.

When the height of extinction sand grip is less than 0.05mm, the reflection number of times of light on the extinction sand grip is less, and extinction effect is relatively poor, and when the height of extinction sand grip was greater than 0.1mm, when carrying out the in-process of drawing of patterns, the extinction sand grip produced the deformation easily to influence extinction effect.

Optionally, the first extinction surface and the second extinction surface are both curved surfaces, and the curvature radii of the first extinction surface and the second extinction surface are both in a range from 0.1mm to 0.3 mm. When the curvature radius R is less than 0.1, the radian is large, and stray light at individual angles is strong, so that the extinction effect is influenced, and when the curvature radius is more than 0.3mm, the curvature radius tends to be linear and the extinction effect is also influenced.

When the distance is less than 0.05mm, the reflection times of the light rays in the first sub extinction part, the second sub extinction part and the third sub extinction part are less, and the extinction effect is influenced; when the distance is more than 0.1mm, the first sub-extinction portion, the second sub-extinction portion, and the third sub-extinction portion are easily deformed when the mold is removed from the mold.

When the included angle is smaller than 10 degrees, the light rays are easily reflected out of the first sub extinction part, the second sub extinction part and the third sub extinction part to influence the extinction effect, and when the included angle is larger than 20 degrees, the width of the second extinction surface is seriously shortened to influence the extinction effect.

Optionally, the second matt surface has a width in the range of 0.001mm to 0.03 mm. When the width of the second extinction surface is smaller than 0.001mm, the processing difficulty is very high, and when the width of the second extinction surface is larger than 0.03mm, the reflection area of the second extinction surface is large and is reflected once, so that the extinction effect of the extinction part is poor, and the ultra-black effect cannot be achieved.

The plurality of first sub-extinction portions 33 are arranged in parallel, the arrangement direction of the plurality of first sub-extinction portions 33 intersects with the extending direction thereof, and the first sub-extinction portions 33 are arranged in a row on each of both sides of the light transmission portion 10.

Alternatively, the second sub-extinction portion 35 may be a solid structure or a part, or may be a virtual structure, such as a groove. The plurality of second sub-extinction portions 35 are arranged in parallel, the arrangement direction of the plurality of second sub-extinction portions 35 intersects with the extending direction thereof, and the second sub-extinction portions 35 are arranged in a row on each of both sides of the light transmission portion 10.

Therefore, the area of direct reflection on the surface of the extinction part 30 can be reduced, the times of reflection of the light rays on the plurality of first sub-extinction parts 33 and the plurality of second sub-extinction parts 35 are increased, and the energy reflected by the light rays is reduced, so that the appearance effects of eliminating stray light and super-black surface are realized, and the good extinction effect is achieved.

Alternatively, in some embodiments, the gap between two adjacent first sub-extinction portions 33 ranges from 0.001mm to 0.03 mm. Specifically, the gap between two adjacent first sub-extinction portions 33 may be, but is not limited to, 0.001mm, 0.003mm, 0.006mm, 0.01mm, 0.015mm, 0.02mm, 0.025mm, 0.03mm, or the like. When the gap between two adjacent first sub-extinction portions 33 is greater than 0.03mm, the extinction effect of the extinction portion 30 is poor; when the gap between two adjacent first sub-extinction portions 33 is less than 0.001mm, the processing is difficult.

It should be understood that the gap between two adjacent first sub extinction portions 33 refers to a minimum distance between orthogonal projections of two adjacent first sub extinction portions 33 on the first surface 311, as shown by d1 in fig. 1.

It should be understood that the gap between two adjacent second sub extinction portions 35 refers to a minimum distance between orthogonal projections of two adjacent second sub extinction portions 35 on the first surface 311, as shown by d2 in fig. 1.

The pitches between the plurality of second sub-extinction portions 35 may be the same or different, that is, the pitches between any two adjacent second sub-extinction portions 35 may be the same or different.

Alternatively, in some embodiments, the sum of the numbers of the first sub extinction portions 33 and the second sub extinction portions 35 ranges from 30 to 200. Specifically, the sum of the numbers of the first sub extinction portions 33 and the second sub extinction portions 35 may be 5 but is not limited to 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, and the like. The number of the first sub extinction portions 33 and the number of the second sub extinction portions 35 may be the same or different, and the difference between the number of the first sub extinction portions 33 and the number of the second sub extinction portions 35 may be less than 5% of the total number of the first sub extinction portions 33 and the second sub extinction portions 35. When the sum of the numbers of the first sub extinction portions 33 and the second sub extinction portions 35 is less than 30, the extinction effect is not good, and when it is more than 200, the extinction effect of the extinction portion 30 is also reduced by sacrificing the size of other extinction features. The first sub-extinction portion 33 or the second sub-extinction portion 35 continuously extending along a straight line is counted as one first sub-extinction portion 33 or second sub-extinction portion 35, and if it is interrupted in the middle, a plurality of first sub-extinction portions 33 or second sub-extinction portions 35 are counted, and for example, the first sub-extinction portion 33 or the second sub-extinction portion 35 having both sides of the light-transmitting hole in the same straight line is counted as two first sub-extinction portions 33 or second sub-extinction portions 35.

Alternatively, when the first and second sub-extinction portions 33 and 35 are located on the same plane, the sum of the numbers of the first and second sub-extinction portions 33 and 35 ranges from 50 to 200 (as in the embodiment of fig. 1 and 3).

Referring to fig. 3, optionally, in some embodiments, an included angle between the first sub-extinction portion 33 and the second sub-extinction portion 35 is a right angle or an acute angle, and one-half (α) of the included angle ranges from 5 ° to 45 °. Specifically, one-half (α) of the angle between the first sub extinction portion 33 and the second sub extinction portion 35 may be, but is not limited to, 5 °, 10 °, 15 °, 20 °, 25 °, 30 °, 35 °, 40 °, 45 °, and the like. In the embodiment of fig. 1, one half (α) of the angle between the first sub extinction portion 33 and the second sub extinction portion 35 is 45 °.

When one half of the included angle between the first sub-extinction portion 33 and the second sub-extinction portion 35 is smaller than 5 degrees, other parts of the extinction main body 31 are easily cut off due to processing errors in the processing process, and the stray light effect is poor; when one half of the included angle between the first sub extinction portion 33 and the second sub extinction portion 35 is larger than 60 °, the area of the non-extinction region on the extinction main body 31 is too large, and the extinction effect is not good.

Referring to fig. 4, in some embodiments, the light extinction portion 30 further includes a plurality of third sub light extinction portions 37, the plurality of third sub light extinction portions 37 are disposed at intervals on the first surface 311, and the plurality of third sub light extinction portions 37 intersect with the plurality of second sub light extinction portions 35 and the plurality of first sub light extinction portions 33, respectively.

Alternatively, the plurality of third sub extinction portions 37 extend in a third direction, and the extending direction of the plurality of third sub extinction portions 37 is perpendicular to the arrangement direction thereof; each of the third sub-extinction portions 37 intersects with the plurality of first sub-extinction portions 33 and the plurality of second sub-extinction portions 35, respectively, wherein the third direction intersects with the first direction and the second direction, respectively.

Alternatively, the third sub-extinction portion 37 may be a solid structure or a part, or may be a virtual structure, such as a groove. The plurality of third sub extinction portions 37 are arranged in parallel, and the arrangement direction of the plurality of third sub extinction portions 37 intersects with the extending direction.

The extinction portion 30 may further include a fourth sub extinction portion, a fifth sub extinction portion, and the like, and the number of the sub extinction portions is not particularly limited in the present application.

Alternatively, in some embodiments, an angular bisector of an angle between the first sub-extinction portion 33 and the second sub-extinction portion 35 is perpendicular to the third sub-extinction portion 37, and the third sub-extinction portion 37 passes through an intersection of the first sub-extinction portion 33 and the second sub-extinction portion 35.

Alternatively, in some embodiments, the sum of the numbers of the first, second, and third sub extinction portions 33, 35, and 37 ranges from 80 to 300. Specifically, the sum of the numbers of the first, second, and third sub-extinction portions 33, 35, and 37 may be, but is not limited to, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 220, 250, 280, 300, and the like. The number of the first, second, and third sub-extinction portions 33, 35, and 37 may be the same or different.

When the sum of the numbers of the first, second, and third sub-extinction portions 33, 35, and 37 is less than 80, the extinction effect of the extinction portion 30 is not good, and when it is more than 300, the extinction effect of the extinction portion 30 is also reduced by sacrificing the size of other extinction features.

Alternatively, the plurality of first sub-extinction portions 33, the plurality of second sub-extinction portions 35, and the plurality of third sub-extinction portions 37 are all extinction grooves or extinction ridges. When the plurality of first sub extinction portions 33, the plurality of second sub extinction portions 35, and the plurality of third sub extinction portions 37 are all extinction grooves, the extinction grooves are formed by recessing the first surface 311 of the extinction main body 31. When the plurality of first sub-extinction portions 33, the plurality of second sub-extinction portions 35, and the plurality of third sub-extinction portions 37 are all extinction ridges, the extinction ridges are disposed on the first surface 311 of the extinction body 31.

Specifically, the depth of the extinction groove may be, but is not limited to, 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, 0.1mm, and the like. When the depth of the extinction groove is less than 0.05mm, the reflection times of light rays in the extinction groove are less, the extinction effect is poor, and when the depth of the extinction groove is more than 0.1mm, the extinction groove is easy to deform in the demolding process, so that the extinction effect is influenced. It should be noted that the depth of the extinction groove in the embodiment of the present application refers to the vertical distance from the deepest position of the extinction groove to the first surface 311.

Referring to fig. 5, in other embodiments, the first sub-extinction portion 33, the second sub-extinction portion 35 and the third sub-extinction portion 37 are extinction ridges, and the height of the extinction ridges ranges from 0.05mm to 0.1 mm. Specifically, the height of the extinction ridges may be, but is not limited to, 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, 0.1mm, or the like. When the height of extinction sand grip is less than 0.05mm, the reflection number of times of light on the extinction sand grip is less, and extinction effect is relatively poor, and when the height of extinction sand grip was greater than 0.1mm, when carrying out the in-process of drawing of patterns, the extinction sand grip produced the deformation easily to influence extinction effect. Note that, the height of the extinction protrusion in the embodiment of the present application refers to a vertical distance from a position where the extinction protrusion is highest to the first surface 311.

In the present embodiment, the perpendicular distance from the intersection line of the first extinction surface 301 and the second extinction surface 302 to the first surface 311 is in the range of 0.05mm to 0.1mm, that is, the height or depth of the first sub-extinction portion 33, the second sub-extinction portion 35, and the third sub-extinction portion 37 in the direction perpendicular to the first surface 311 is in the range of 0.05mm to 0.1 mm; specifically, it may be, but not limited to, 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, 0.1mm, etc. When the vertical distance is less than 0.05mm, the reflection times of the light rays in the first sub extinction part 33, the second sub extinction part 35 and the third sub extinction part 37 are less, and the extinction effect is influenced; when the vertical distance is more than 0.1mm, the first, second, and third sub-extinction portions 33, 35, and 37 are easily deformed when the mold is released.

When the curvature radius R is less than 0.1, the radian is large, and stray light at individual angles is strong, so that the extinction effect is influenced, and when the curvature radius is more than 0.3mm, the curvature radius tends to be linear and the extinction effect is also influenced.

In the present embodiment, the distance between the intersection line of the first extinction surface 301 and the first surface 311 and the intersection line of the second extinction surface 302 and the first surface 311 ranges from 0.05mm to 0.1mm, and specifically, may be, but is not limited to, 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, 0.1mm, and the like.

In this embodiment, the at least one of the extinction surfaces includes the first extinction surface 301 or includes the second extinction surface 302 and the third extinction surface 303.

In the present embodiment, the perpendicular distance from the intersection line of the first extinction surface 301 and the second extinction surface 302 to the first surface 311 is in the range of 0.05mm to 0.1mm, that is, the height or depth of the first sub-extinction portion 33, the second sub-extinction portion 35, and the third sub-extinction portion 37 in the direction perpendicular to the first surface 311 is in the range of 0.05mm to 0.1 mm; specifically, it may be, but not limited to, 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, 0.1mm, etc. When the vertical distance is less than 0.05mm, the reflection times of the light rays in the first sub extinction part 33, the second sub extinction part 35 and the third sub extinction part 37 are less, and the extinction effect is influenced; when the vertical distance is more than 0.1mm, the first, second, and third sub-extinction portions 33, 35, and 37 are easily deformed when the mold is released.

When the included angle is less than 20 °, the strength of the mold used for preparing the first, second and third sub-extinction portions 33, 35 and 37 is insufficient, and when the included angle is greater than 70 °, the number of times of reflection of light on the first, second and third sub-extinction portions 33, 35 and 37 is small, which affects the extinction effect.

In the present embodiment, the angle between the second light-eliminating surface 302 and the first surface 311 ranges from 10 ° to 20 °, specifically, the angle between the second light-eliminating surface 302 and the first surface 311 ranges from 10 °, 12 °, 14 °, 15 °, 16 °, 18 °, 20 °, and so on. When the included angle is smaller than 10 °, the light is easily reflected out of the first sub-extinction portion 33, the second sub-extinction portion 35, or the third sub-extinction portion 37, which affects the extinction effect, and when the included angle is larger than 20 °, the width of the second extinction surface 35 is greatly shortened, which affects the extinction effect.

When the width of the second extinction surface 302 is less than 0.001mm, the processing difficulty is high, and when the width of the second extinction surface 302 is greater than 0.03mm, the reflection area of the second extinction surface 302 is large and is once reflected, so that the extinction effect of the extinction part 30 is poor and the ultra-black effect cannot be achieved. The term "width" in this application refers to the perpendicular distance between the two parallel lines on the face that are closest.

Referring to fig. 11, fig. 11 shows a sixth embodiment of the first, second and third sub-extinction portions 33, 35 and 37 of the present application, which is different from the fifth embodiment in that the first, second and third extinction surfaces 301, 302 and 303 are recessed in the first surface 311.

In this embodiment, the at least one extinction surface includes a first extinction surface 301, a second extinction surface 302, and a third extinction surface 303, or includes a fourth extinction surface 304, a fifth extinction surface 305, and a sixth extinction surface 306.

In the present embodiment, the first extinction surface 301 is parallel to the third extinction surface 303; the fourth extinction surface 304 is parallel to the sixth extinction surface 306.

In the present embodiment, the included angle between the first extinction surface 301 and the sixth extinction surface 306 ranges from 20 ° to 70 °; specifically, the included angle between the first extinction surface 301 and the sixth extinction surface 306 may be, but is not limited to, 20 °, 30 °, 40 °, 45 °, 50 °, 60 °, 70 °, and the like. The included angle between the third extinction surface 303 and the fourth extinction surface 304 is 20 degrees to 70 degrees; specifically, the included angle between the third and fourth light-eliminating surfaces 303, 304 may be, but is not limited to, 20 °, 30 °, 40 °, 45 °, 50 °, 60 °, 70 °, and the like. When the included angle is less than 20 °, the strength of the mold used for preparing the first, second and third sub-extinction portions 33, 35 and 37 is insufficient, and when the included angle is greater than 70 °, the number of times of reflection of light on the first, second and third sub-extinction portions 33, 35 and 37 is small, which affects the extinction effect.

In this embodiment, the included angle between the first extinction surface 301 and the first surface 311 is equal to the included angle between the second extinction surface 302 and the first surface 311, so that the reflection at each position on the light extinction portion 30 has a better extinction effect (or super-black effect). In other embodiments, the included angle between the first extinction surface 301 and the first surface 311 and the included angle between the second extinction surface 302 and the first surface 311 may not be equal, and the present application is not limited in this respect.

In the present embodiment, the second extinction surface 302 and the fifth extinction surface 305 are respectively parallel to the first surface 311. Thus, the extinction part has better extinction effect.

When the distance between the second extinction surface 302 and the first surface 311 and the distance between the fifth extinction surface 305 and the first surface 311 are greater than 0.03mm, the number of times the light is reflected on the first, second and third sub-extinction portions 33, 35 and 37 is small, thereby affecting the extinction effect.

In the present embodiment, the width of the second light-eliminating surface 302 ranges from 0.001mm to 0.02 mm; specifically, the width of the second extinction surface 302 may be, but is not limited to, 0.001mm, 0.003mm, 0.005mm, 0.008mm, 0.01mm, 0.012mm, 0.015mm, 0.018mm, 0.02mm, and the like.

When the widths of the second extinction surface 302 and the fifth extinction surface 305 are smaller than 0.001mm, the existing processing technology is difficult to process, and when the widths of the second extinction surface 302 and the fifth extinction surface 305 are larger than 0.02mm, the reflection areas of the second extinction surface 302 and the fifth extinction surface 305 are larger, so that the extinction effect of ultra-black surfaces cannot be achieved.
