Description

取像模组、电子装置及汽车Capture module, electronic device and car

技术领域Technical field

本发明涉及一种取像模组、电子装置及汽车。The invention relates to an image capturing module, an electronic device and an automobile.

背景技术Background technique

由于车身结构的限制，家用汽车在视野上存在多个盲区，大货车的盲区更大。司机无法看到这些盲区，从而容易引发交通事故。Due to the limitation of the body structure, family cars have multiple blind spots in the field of vision, and large trucks have larger blind spots. Drivers cannot see these blind spots, which can easily cause traffic accidents.

车身两边的后视镜只能看到车身两侧较为狭窄的空间，并不能收集到车身周围的全部信息。如当由辅路上主路时，司机从左后视镜不能观察到完整的左侧汽车信息，假如通过加速大角度切上最内侧车道，很容易与正在最内侧车道高速行驶的汽车发生碰撞。虽然，通过调整好后视镜的角度以及加装一个凸视镜可将两侧的盲区减小，但实际效果甚微。The rearview mirrors on both sides of the body can only see the narrower space on both sides of the body, and cannot collect all the information around the body. For example, when driving from the main road on the auxiliary road, the driver cannot observe the complete left-side car information from the left rearview mirror. If he cuts into the innermost lane by accelerating at a large angle, it is easy to collide with a car driving at a high speed in the innermost lane. Although the blind spots on both sides can be reduced by adjusting the angle of the rearview mirror and installing a convex mirror, the actual effect is very small.

参考图1所示，本申请实施例中的取像模组100由物侧至像侧依次包括具有负屈折力的第一透镜L1、具有正屈折力的第二透镜L2、具有屈折力的第三透镜L3、具有正屈折力的第四透镜L4及具有负屈折力的第五透镜L5。As shown in FIG. 1, the imaging module 100 in the embodiment of the present application includes a first lens L1 with a negative refractive power, a second lens L2 with a positive refractive power, and a second lens with a refractive power from the object side to the image side. The three lens L3, the fourth lens L4 with positive refractive power, and the fifth lens L5 with negative refractive power.

In addition, there is an imaging surface S15 on the image side of the fifth lens L5, and the imaging surface S15 may be the photosensitive surface of the photosensitive chip.

其中，第二透镜L2的物侧面S3为凸面。第四透镜L4的物侧面S7和像侧面S8均为凸面。第五透镜L5的物侧面S9为凹面，像侧面S10为凸面。Among them, the object side surface S3 of the second lens L2 is convex. Both the object side surface S7 and the image side surface S8 of the fourth lens L4 are convex surfaces. The object side surface S9 of the fifth lens L5 is a concave surface, and the image side surface S10 is a convex surface.

另外，第一透镜L1、第二透镜L2、第三透镜L3、第四透镜L4、第五透镜L5的非球面面型公式为:In addition, the aspheric surface type formulas of the first lens L1, the second lens L2, the third lens L3, the fourth lens L4, and the fifth lens L5 are:

其中，Z是非球面上相应点到与表面顶点相切的平面的距离，r是非球面上相应点到光轴的距离，c是非球面顶点的曲率，k是圆锥常数，Ai为非球面面型公式中与第i项高次项相对应的系数。Among them, Z is the distance from the corresponding point on the aspheric surface to the plane tangent to the apex of the surface, r is the distance from the corresponding point on the aspheric surface to the optical axis, c is the curvature of the aspheric apex, k is the conic constant, and Ai is the aspheric surface formula The coefficient corresponding to the higher-order item of the i-th term.

在一些实施例中，取像模组100还包括光阑ST0。光阑ST0可设置于第一透镜L1的物侧与第四透镜L4之间。具体地，在一些实施例中，光阑ST0可设置于第二透镜L2与第三透镜L3之间或第三透镜L3与第四透镜L4之间。In some embodiments, the imaging module 100 further includes a stop ST0. The stop ST0 may be provided between the object side of the first lens L1 and the fourth lens L4. Specifically, in some embodiments, the stop ST0 may be disposed between the second lens L2 and the third lens L3 or between the third lens L3 and the fourth lens L4.

在一些实施例中，第一透镜L1、第二透镜L2、第三透镜L3、第四透镜L4及第五透镜L5的材质均为塑料，此时，塑料材质的透镜能够减少取像模组100的重量并降低生成成本。在一些实施例中，第一透镜L1、第二透镜L2、第三透镜L3、第四透镜L4及第五透镜L5的材质均为玻璃，此时，取像模组100能够耐受较高的温度且具有较好的光学性能。在另一些实施例中，也可以仅是第一透镜L1为玻璃材质，而其他透镜为塑料材质，此时，最靠近物侧的第一透镜L1能够较好地耐受物侧的环境温度影响，且由于其他透镜为塑料材质的关系，从而使取像模组100保持较低的生产成本。又或者，在一些实施例中，第一透镜L1的材质为玻璃，其他透镜的材质可任意组合。In some embodiments, the materials of the first lens L1, the second lens L2, the third lens L3, the fourth lens L4, and the fifth lens L5 are all plastic. In this case, the plastic lens can reduce the imaging module 100 Weight and reduce production costs. In some embodiments, the materials of the first lens L1, the second lens L2, the third lens L3, the fourth lens L4, and the fifth lens L5 are all glass. In this case, the imaging module 100 can withstand higher Temperature and good optical properties. In other embodiments, it is also possible that only the first lens L1 is made of glass and the other lenses are made of plastic. In this case, the first lens L1 closest to the object side can better withstand the environmental temperature of the object side. And because the other lenses are made of plastic materials, the production cost of the imaging module 100 is kept low. Or, in some embodiments, the material of the first lens L1 is glass, and the materials of other lenses can be combined arbitrarily.

在一些实施例中，取像模组100设置有玻璃材质的红外滤光片L6，红外滤光片L6设置于第五透镜L5的像侧。红外滤光片L6包括物侧面S11及像侧面S12。红外滤光片L6用于过滤成像的光线，具体用于隔绝红外光，防止红外光到达成像面S15，从而防止红外光对正常影像的色彩与清晰度造成影响，进而提高取像模组100的成像品质。In some embodiments, the imaging module 100 is provided with an infrared filter L6 made of glass, and the infrared filter L6 is provided on the image side of the fifth lens L5. The infrared filter L6 includes an object side surface S11 and an image side surface S12. The infrared filter L6 is used to filter the light for imaging, specifically to isolate infrared light and prevent infrared light from reaching the imaging surface S15, thereby preventing infrared light from affecting the color and clarity of the normal image, thereby improving the imaging module 100 Image quality.

在一些实施例中，取像模组100还包括保护玻璃L7。保护玻璃L7包括物侧面S13及像侧面S14。保护玻璃L7设置于红外滤光片L6的像侧以在后续组装成模组时能够靠近感光芯片，从而起到保护感光芯片的作用。In some embodiments, the imaging module 100 further includes a protective glass L7. The cover glass L7 includes an object side surface S13 and an image side surface S14. The protective glass L7 is arranged on the image side of the infrared filter L6 so as to be close to the photosensitive chip when subsequently assembled into a module, thereby protecting the photosensitive chip.

In some of these embodiments, CT2/CT3 may be 1.10, 1.50, 2.00, 2.50, 3.00, 3.50, and 4.00. When the above relationship is satisfied, the problem of poor molding of the second lens L2 and the third lens L3 can be better avoided, and the uniformity of lens molding can be increased at the same time.

ΣCT/TL＜0.70；ΣCT/TL＜0.70;

其中，ΣCT为第一透镜L1、第二透镜L2、第三透镜L3、第四透镜L4和第五透镜L5于光轴上的厚度的总和，TL为第一透镜L1的物侧面S1至取像模组100的成像面S15于光轴上的距离。在其中的一些实施例中，ΣCT/TL可以为0.42、0.45、0.50、0.55或0.62。满足上述关系时，可合理设置各透镜的厚度，减小各透镜的加工难度以提升良率，同时缩短取像模组100于光轴方向的尺寸，并增大机械焦距，从而有利于调焦。Among them, ΣCT is the sum of the thickness of the first lens L1, the second lens L2, the third lens L3, the fourth lens L4 and the fifth lens L5 on the optical axis, and TL is the object side surface S1 of the first lens L1 to the image capturing The distance of the imaging surface S15 of the module 100 on the optical axis. In some of these embodiments, ΣCT/TL may be 0.42, 0.45, 0.50, 0.55, or 0.62. When the above relationship is satisfied, the thickness of each lens can be set reasonably, the processing difficulty of each lens can be reduced to improve the yield, and the size of the imaging module 100 in the optical axis direction can be shortened, and the mechanical focal length can be increased, thereby facilitating focusing .

ET4≥0.47mm；ET4≥0.47mm;

其中，ET4为第四透镜L4于垂直光轴方向的半径为3.3mm处所对应的透镜厚度，ET4的单位为mm。在其中一些实施例中，ET4的取值可以为0.50mm、0.55mm、0.60mm、0.80mm、0.90mm、1.00mm、1.20mm、1.40mm或1.50mm。满足上述关系时，可减小第四透镜L4的加工难度，提高良率。Among them, ET4 is the lens thickness corresponding to the radius of the fourth lens L4 in the direction perpendicular to the optical axis of 3.3 mm, and the unit of ET4 is mm. In some embodiments, the value of ET4 can be 0.50mm, 0.55mm, 0.60mm, 0.80mm, 0.90mm, 1.00mm, 1.20mm, 1.40mm, or 1.50mm.

The radius of curvature at the axis, R6 is the radius of curvature of the image side surface S6 of the third lens L3 at the optical axis. In some of the embodiments, the relationship of |R3|/|R4| may be 0.15, 0.20, 1.00, 2.50, 3.50, 4.50, 4.90, or 4.95; the relationship of |R5|/|R6| may be 1.30, 1.50, 1.60, 1.70, 1.80 or 1.90. When the above relationship is satisfied, the curvature radii of the object side and image side of the second lens L2 and the third lens L3 on the optical axis can be set reasonably to make the difference between the curvature radii of the two surfaces of the second lens L2 and the optical axis The two surfaces of the third lens L3 have similar radii of curvature at the optical axis, so that the second lens L2 and the third lens L3 are easy to produce and process. If the radius of curvature of the object side or the image side is too large, a larger focal length will be produced and deviations will easily occur; if the difference in the radius of curvature of the two surfaces is too large, it will increase the processing difficulty and reduce the accuracy stability.

0≤∣V2-V5∣＜35.00；0≤∣V2-V5∣＜35.00;

其中，V2为第二透镜L2的色散系数，V5为第五透镜L5的色散系数。在其中的一些实施例中，∣V2-V5∣的关系可以为1.00、2.00、2.50、10.00、11.00、28.00或28.50。通过对第二透镜L2和第三透镜L3的材料进行合理配置以满足上述关系，从而减小取像模组100的色差，提升成像品质。Among them, V2 is the dispersion coefficient of the second lens L2, and V5 is the dispersion coefficient of the fifth lens L5. In some of these embodiments, the relationship of ∣V2-V5∣ can be 1.00, 2.00, 2.50, 10.00, 11.00, 28.00 or 28.50.

(CT4-CT5)/(α4-α5)＜0；(CT4-CT5)/(α4-α5)<0;

其中，CT4为第四透镜L4于光轴上的厚度，CT4的单位为mm；CT5为第五透镜L5于光轴上的厚度，CT5的单位为mm；α4为第四透镜L4的热膨胀系数，α4的单位为10 ^-6/k；α5为第五透镜L5的热膨胀系数，α5的单位为10 ^-6/k。在其中的一些实施例中，(CT4-CT5)/(α4-α5)的关系可以为-8.00、-6.00、-4.00或-3.00。通过对第四透镜L4和第五透镜L5于光轴上的厚度以及各自的材料进行合理搭配以满足上述关系，从而减小温度对取像模组100的影响，使取像模组100在高温或低温时依然保持良好的成像品质。另外，若第四透镜L4和第五透镜L5为胶合镜片时，还能够减小两个透镜于光轴上的厚度差异及材料特性差异，降低胶合镜片开裂的风险。 Among them, CT4 is the thickness of the fourth lens L4 on the optical axis, and the unit of CT4 is mm; CT5 is the thickness of the fifth lens L5 on the optical axis, and the unit of CT5 is mm; α4 is the thermal expansion coefficient of the fourth lens L4, The unit of α4 is 10 ^-6 /k; α5 is the thermal expansion coefficient of the fifth lens L5, and the unit of α5 is 10 ^-6 /k.
