In order to solve the problem that stray light is difficult to improve in the optical imaging lens among the prior art, the utility model provides a lens, optical imaging lens and mobile terminal.

As shown in fig. 1 to 10, at least one side surface of the lens 70 includes an optically effective area 10, an optical mechanism area 20, and an ink layer in a direction away from the optical axis, the optically effective area 10 being used for imaging; the optical mechanism area 20 is positioned outside the optical effective area 10, the optical mechanism area 20 is used for bearing and mounting, and the optical mechanism area 20 is provided with a groove structure 30; the ink layer is disposed on the groove structure 30.

The optically effective area 10 is provided to facilitate the imaging of light through the optically effective area 10, and the optical mechanism area 20 is provided for the bearing of the lens 70 to facilitate the stable mounting of the lens 70 in the lens barrel. By arranging the groove structure 30 on the optical mechanism area 20, the groove structure 30 can absorb light rays emitted to the optical mechanism area 20, the light rays are reduced from being reflected on the optical mechanism area 20, the light rays which are not used for imaging are reduced from being reflected to the optical effective area 10, the generation of stray light is reduced, and the imaging quality of the lens 70 is ensured. Disposing the ink layer on the groove structure 30 may increase further absorption of light by the groove structure 30 to further reduce the generation of stray light. The arrangement enables the lens 70 to effectively absorb stray light, greatly reduces the generation of stray light, and increases the imaging quality of the lens 70.

It should be noted that the ink layer is black, and the black ink layer has the greatest absorption efficiency of light to reduce stray light.

As shown in fig. 2, 6 and 9, the groove structure 30 is a ring groove that is continuously provided around the circumference of the optically active region 10. The groove structure 30 is configured as a ring groove, so that the groove structure 30 can effectively absorb light around the optically effective region 10, and stray light entering the optically effective region 10 from any direction can be absorbed by the groove structure 30, so that the stray light around the optically effective region 10 can be absorbed.

As shown in fig. 2, 3, 6, 7, 9 and 10, the groove structure 30 includes a first surface segment 31, a second surface segment 32 and a third surface segment 33, a first end of the second surface segment 32 is connected to the first surface segment 31, and the first surface segment 31 extends from the second surface segment 32 in a direction away from the optical axis; the second end of the second face segment 32 is connected to the third face segment 33, and the third face segment 33 extends from the second face segment 32 to a direction close to the optical axis. Alternatively, the first face segment 31 and the third face segment 33 are both angled with respect to the optical axis. The arrangement makes the opening of the groove structure 30 flaring, so that the area of incident light received by the groove structure 30 can be increased, the efficiency of light absorption is increased, and the lens 70 has a good effect of reducing stray light.

As shown in fig. 3, 7, and 10, an angle α 1 between the first surface segment 31 and the optical axis is 20 ° or more and 90 ° or less. If the included angle α 1 between the first surface segment 31 and the optical axis is smaller than 20 °, the included angle between the first surface segment 31 and the second surface segment 32 is too small to facilitate the light to enter the groove structure 30, and to facilitate the improvement of stray light. The included angle alpha 1 between the first surface section 31 and the optical axis is larger than 90 degrees, the included angle between the first surface section 31 and the second surface section 32 is too large, the groove structure 30 cannot be formed, and the light can be reflected on the first surface section 31 to form stray light, so that the stray light is not favorably improved.

As shown in fig. 3, 7, and 10, the angle α 2 between the second surface segment 32 and the optical axis is 80 ° or more and 100 ° or less. The arrangement is such that the second surface segment 32 is approximately perpendicular to the optical axis, which facilitates the application of the ink layer within the groove structure 30, so that the groove structure 30 and the ink layer absorb stray light.

As shown in fig. 3, 7, and 10, an included angle α 3 between the third surface section 33 and the optical axis is 20 ° or more and 90 ° or less; if the included angle α 3 between the third surface segment 33 and the optical axis is smaller than 20 °, the included angle between the third surface segment 33 and the second surface segment 32 is too small to facilitate the light to enter the groove structure 30, and to facilitate the improvement of stray light. The included angle alpha 3 between the third surface section 33 and the optical axis is larger than 90 degrees, the included angle between the third surface section 33 and the second surface section 32 is too large, the groove structure 30 cannot be formed, and the light can reflect light on the third surface section 33 to form stray light, so that the stray light is not favorably improved.

As shown in fig. 3, 7 and 10, a perpendicular distance L between an end of the first face segment 31 away from the second face segment 32 and an end of the third face segment 33 away from the second face segment 32 is equal to or greater than 0.2 mm. Or the maximum distance of the openings of the groove structure 30 is equal to or greater than 0.2 mm. If the vertical distance L is less than 0.2 mm, the light is not easy to enter the groove structure 30, which is not favorable for absorbing the light. The vertical distance L is set to be larger than or equal to 0.2 mm, so that the groove structure 30 can absorb light rays, and stray light is effectively reduced.

As shown in fig. 3, 7, and 10, the distance L1 of the first face section 31 in the direction perpendicular to the optical axis is equal to or greater than 0.02 mm. If the distance L1 of the first surface segment 31 in the direction perpendicular to the optical axis is less than 0.02 mm, the length of the first surface segment 31 is too small to facilitate the reflection of light in the groove structure 30 and the absorption of stray light. The distance L1 between the first surface segment 31 and the optical axis is greater than or equal to 0.02 mm, which facilitates the reflection and absorption of the first surface segment 31 to the light in the groove structure 30, and reduces the generation of stray light.

As shown in fig. 3, 7, and 10, the distance L2 of the second segment 32 in the direction perpendicular to the optical axis is equal to or greater than 0.05 mm. If the distance L2 of the second surface segment 32 in the direction perpendicular to the optical axis is less than 0.05 mm, the length of the second surface segment 32 is too small, and the absorption area of the light is small, which is not favorable for absorbing the light. The distance L2 between the second surface segment 32 and the optical axis is greater than or equal to 0.05 mm, which facilitates the reflection and absorption of the second surface segment 32 to the light in the groove structure 30, and reduces the generation of stray light.

As shown in fig. 3, 7, and 10, the distance L3 of the third surface segment 33 in the direction perpendicular to the optical axis is equal to or greater than 0.02 mm. If the distance L3 of the third surface segment 33 in the direction perpendicular to the optical axis is less than 0.02 mm, the length of the third surface segment 33 is too small to facilitate the reflection of light in the groove structure 30 and the absorption of stray light. And the distance L3 between the third surface section 33 and the direction perpendicular to the optical axis is set to be greater than or equal to 0.02 mm, so that the third surface section 33 can reflect and absorb light rays in the groove structure 30, and stray light is reduced.

As shown in fig. 1, fig. 5 and fig. 8, the optical imaging lens includes a lens barrel 60, a plurality of lenses 70 and a plurality of light shields 80, wherein the plurality of lenses 70 are arranged at intervals along an axial direction of the lens barrel 60, and at least one lens 70 of the plurality of lenses 70 is the above-mentioned lens 70; the light shielding member 80 is disposed between adjacent two lenses 70. The optical imaging lens with the lens 70 can effectively reduce the generation of stray light, and ensures the imaging quality of the optical imaging lens.

Specifically, the method comprises the following steps. The mobile terminal comprises the optical imaging lens. The mobile terminal with the optical imaging lens has good imaging quality.

The mobile terminal can be a mobile phone, a computer, a tablet, a television and the like.

As shown in fig. 3, 7 and 10, the thickness H1 of the ink layer on the first face section 31, the thickness H2 of the ink layer on the second face section 32 and the thickness H3 of the ink layer on the third face section 33, and the thickness H1, the thickness H2 and the thickness H3 are each 0.005 mm or more and 0.02 mm or less. The thickness of the ink layer is limited within the range of 0.005 mm to 0.02 mm, so that the ink layer can be uniformly laid on the groove structure 30, and meanwhile, the overflow of the ink layer during coating can be effectively reduced.

Example one

In the particular embodiment shown in fig. 3, the end of the first face segment 31 remote from the second face segment 32 is remote from the second face segment 32 relative to the end of the third face segment 33 remote from the second face segment 32. This arrangement facilitates the light to be incident into the groove structure 30, and facilitates the absorption of the light by the groove structure 30.

As shown in fig. 3, when the end of the first surface segment 31 away from the second surface segment 32 is away from the second surface segment 32 relative to the end of the third surface segment 33 away from the second surface segment 32, the optical mechanism area 20 has an ink stopping structure 40, and the ink stopping structure 40 is located between the third surface segment 33 and the optical effective area 10. The arrangement of the ink stopping structure 40 can limit the ink layer at the groove structure 30, and prevent the ink material from flowing to the optically effective area 10 when the ink layer is coated, so as to ensure that the optically effective area 10 can stably form images.

It should be noted that the ink stopping structure 40 mainly functions as an overflow of the ink material, and reduces the flow of the ink material to the region except the groove.

In the embodiment shown in fig. 4, the ink stopping structure 40 is a rib structure, and the rib structure includes a first side surface 51, a top surface 52 and a second side surface 53 connected in sequence, the first side surface 51 is connected to the third surface section 33, and the second side surface 53 is connected to or spaced apart from the optically active area 10. The ink stopping structure 40 is arranged to be a rib structure, so that the ink can be effectively stopped, and the ink is prevented from flowing to the optical effective area 10, so that the stable work of the optical effective area 10 is ensured. The ink stopping structure 40 is configured as a rib structure, which can effectively prevent the ink material from overflowing to the optically effective area 10.

As shown in fig. 4, an angle β 1 between the first side surface 51 and the optical axis is equal to or greater than 5 ° and equal to or less than 30 °. If the included angle β 1 is less than 5 °, the included angle between the first side surface 51 and the third surface segment 33 is too small, which is not favorable for coating the ink on the first side surface 51. If the included angle β 1 is greater than 30 °, the included angle between the first side surface 51 and the third surface segment 33 becomes too large, so that the ink easily flows into the optically effective area 10. Setting the angle β 1 between 5 ° and 30 ° facilitates the coating of the ink material and also ensures stable operation of the optically effective area 10.

As shown in fig. 4, an angle β 2 between the second side surface 53 and the optical axis is 60 ° or more and 100 ° or less. If the included angle β 2 is less than 60 °, the light is reflected at the top surface 52, which is not favorable for reducing stray light. If the angle β 2 is larger than 100 °, the ink easily overflows to the optically effective area. The included angle β 2 is set to 60 ° to 100 °, which is advantageous to reduce stray light and also to prevent ink from flowing to the optically effective area 10, so as to ensure stable operation of the optically effective area 10.

As shown in fig. 4, the top surface 52 is parallel to the third face section 33. By the arrangement, when light rays enter the top surface 52, the top surface 52 does not reflect the light rays to the optical effective area 10, and the light rays are reflected to the groove structure 30, so that the generation of stray light is effectively reduced, and the imaging quality of the lens is improved.

As shown in fig. 4, the distance L4 between the top surface 52 and the third face section 33 is 0.005 mm or more and 0.05 mm or less. The arrangement is such that the first side surface 51 has a length that effectively absorbs the ink material as it overflows, preventing the ink material from overflowing to the optically active area 10.

As shown in fig. 4, the length L5 of the top surface 52 is 0.005 mm or more and 0.05 mm or less. The ink stopping structure 40 has a certain structural strength, and is beneficial to absorbing light, reducing the reflection of the light to the optical effective area 10 and reducing the generation of stray light.

In this embodiment, black paste having a high viscosity and relatively low fluidity is preferably used as the material of the ink layer.

As shown in fig. 3, in a case where the groove structure 30 has a height difference, or in a case where the first surface section 31 and the third surface section 33 have a height difference, the height difference h between the first surface section 31 and the third surface section 33 is greater than 0 and less than or equal to 0.1 mm, which facilitates the manufacturing of the groove structure 30. Setting the height difference h in the range of 0 to 0.1 mm can avoid the first surface section 31 from being higher than the third surface section 33 by too much length, and the stray light is formed by reflection on the first surface section 31.

Example two

The difference from the first embodiment is that the structure of the groove structure 30 is different.

In the particular embodiment shown in fig. 7, the end of the first face segment 31 remote from the second face segment 32 is adjacent to the second face segment 32 relative to the end of the third face segment 33 remote from the second face segment 32. This arrangement facilitates the light to be incident into the groove structure 30, and facilitates the absorption of the light by the groove structure 30.

As shown in fig. 7, when the end of the first surface segment 31 away from the second surface segment 32 is close to the second surface segment 32 relative to the end of the third surface segment 33 away from the second surface segment 32, the optical mechanism area 20 has an ink stopping structure 40, and the ink stopping structure 40 is connected to the first surface segment 31. Since the first surface segment 31 is short relative to the third surface segment 33 in this embodiment, and overflows from the first surface segment 31 when the amount of ink is large, but does not flow from the third surface segment 33, the ink stopping structure 40 is only disposed between the first surface segment 31 and the outer periphery of the light mechanism region, so as to reduce the overflow of the ink to the outside of the groove structure 30.

As shown in fig. 7, the ink stopping structure 40 is an ink overflow plane, and an included angle γ between the ink overflow plane and the optical axis is greater than or equal to 20 ° and less than or equal to 90 °. Since the ink material does not overflow to the optically effective area 10 because of the absence of imaging between the first surface section 31 and the periphery of the optical mechanism area, the ink stopping structure 40 is disposed at the ink overflow plane to enable the overflowed ink material to be coated on the ink overflow plane to further increase the absorption of light by the optical mechanism area. The included angle gamma is limited within the range of 20 degrees to 90 degrees, so that the ink material can be coated on the ink overflowing plane conveniently.

As shown in fig. 7, the height L6 of the ink overflow plane is 0.05 mm or more. The ink overflow plane can be effectively ensured to absorb the ink, the ink is prevented from overflowing to other structures, and the quality of the lens is favorably controlled.

In this embodiment, black paste having a high viscosity and relatively low fluidity is preferably used as the material of the ink layer.

As shown in fig. 7, in a case where the groove structure 30 has a height difference, or in a case where the first surface section 31 and the third surface section 33 have a height difference, the height difference h between the first surface section 31 and the third surface section 33 is greater than 0 and less than or equal to 0.1 mm, which facilitates the manufacturing of the groove structure 30. Setting the height difference h in the range of 0 to 0.1 mm can avoid the length of the third section 33 higher than the first section 31 from being too large, and stray light is formed by reflection on the third section 33.

EXAMPLE III

The difference from the first embodiment is that the specific structure of the groove structure 30 is different.

In the specific embodiment shown in fig. 10, the end of the first face section 31 remote from the second face section 32 is located on the same plane as the end of the third face section 33 remote from the second face section 32. This arrangement facilitates the fabrication of the groove structure 30.

Since the first face section 31 and the third face section 33 in the present embodiment have no level difference, the ink stop structure 40 may not be provided. The ink layer can be made of black glue with high viscosity and relatively low fluidity, or ink with low viscosity and relatively high fluidity.
