Description

Technical Field

[0001] The present application relates to the field of optical elements, and in particular, to a camera lens. Background Art

[0002] As people's quality of life improves, the demand for various portable communication devices is also increasing, and people's requirements for lens functionality and image quality are becoming increasingly higher. Wearable devices are rapidly becoming popular today, and the sensitive components in these devices must be able to synchronize with the environment regardless of where people are. However, various smart wearable devices are used in hot and cold environments, which requires smart devices to adapt to different environments and maintain stable image quality. Failure to consider these aspects may cause device failure.

[0003] Lenses installed in small, portable video communication devices must not only meet the requirements of being compact enough to fit within the device's space, but also take into account the impact resistance of the application environment and the impact of indoor and outdoor temperature fluctuations on image quality. Furthermore, improper placement of support components between adjacent lenses can also affect the assembly stability of the imaging lens, thereby affecting the imaging quality. Therefore, how to rationally configure the spatial arrangement and related parameters of lenses and support components to improve assembly stability and balance or minimize the impact of the external environment on the lens is a hot topic for researchers in this field.

[0019] The second aspect of the present application provides a camera lens, which includes: a lens barrel, a lens group and a support member group disposed in the lens barrel. Among them, the lens group includes, in order from the object side to the image side along the optical axis: a first lens with a negative focal power, a second lens with a focal power, a third lens with a positive focal power, a fourth lens with a negative focal power, a fifth lens with a positive focal power, and a sixth lens with a negative focal power; the support member group includes: a first support member disposed on the image side of the first lens and at least partially contacting the image side surface of the first lens, a second support member disposed on the image side of the second lens and at least partially contacting the image side surface of the second lens, a third support member disposed on the image side of the third lens and at least partially contacting the image side surface of the third lens, and a fourth support member disposed on the image side of the fourth lens and at least partially contacting the image side surface of the fourth lens; the inner diameter of the object side surface or the image side surface of the second support member is smaller than the inner diameters of the other support members in the support member group; the effective focal length f of the camera lens and the maximum semi-field angle Semi-FOV of the camera lens satisfy: 0.8mm < f / tan(Semi-FOV) < 0.95mm; the central thickness CT3 of the third lens on the optical axis, the central thickness CT2 of the second lens on the optical axis, and the distance EP12 along the optical axis from the image side surface of the first support member to the object side surface of the second support member satisfy: 4.7mm -1 < CT3 / CT2 / EP12 < 6.95mm -1 ; the distance EP34 along the optical axis from the image side surface of the third support member to the object side surface of the fourth support member and the central thickness CT4 of the fourth lens on the optical axis satisfy: 1.42 < EP34 / CT4 < 2.6.

[0020] The camera lens provided by the present application is a six-piece wide-angle lens. By reasonably distributing the positive and negative focal powers of each lens and satisfying: 0.8mm < f / tan(Semi-FOV) < 0.95mm, the ratio of the effective focal length of the lens to the tangent of the field angle is reasonably controlled, ensuring the effective focal length of the lens while ensuring the wide-angle characteristics of the lens and ensuring the imaging quality. The inner diameter of the second support member is the minimum among all the support members, which is equivalent to the minimum light-transmitting area of the second lens among all the lenses. That is to say, the light passing aperture of the second lens controls the field angle of the lens within its specifications; at the same time, the present application takes into account that the sensitivity of the focal length is relatively high at the second lens and the air gap adjacent to the second lens. By reasonably controlling the central thicknesses of the second lens and the third lens, the air gap between the second lens and the third lens on the optical axis, the maximum thickness of the second support member, the air gap between the first lens and the second lens on the optical axis, and the thickness of the non-light-transmitting area of the second lens, the second lens can be stably supported by the front and rear lenses, and the influence of the change in the lens gap on the focal length caused by temperature or dropping is reduced, thereby stabilizing the imaging quality.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The following embodiments only express several implementation methods of the present application, and their descriptions are relatively specific and detailed, but they should not be understood as limiting the scope of the patent of the present application.

[0041] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. Figure 1 The following figure shows the structural arrangement of a camera lens according to the present application and a schematic diagram of some parameters. It should be understood by those skilled in the art that some parameters of lenses commonly used in the art (such as the center thickness CT1 of the first lens on the optical axis) are not shown in the figure. Figure 1 As shown in Figure 1 Only some parameters of the lens barrel and the supporting member of a camera lens of the present application are shown as examples to facilitate a better understanding of the present invention. Figure 1 As shown, EP01 represents the distance from the object side end face of the lens barrel to the object side face of the first supporting member along the optical axis direction, CP1 is the maximum thickness of the first supporting member along the optical axis direction, CP2 is the maximum thickness of the second supporting member along the optical axis direction, EP12 represents the distance from the image side face of the first supporting member to the object side face of the second supporting member along the optical axis direction, EP23 represents the distance from the image side face of the second supporting member to the object side face of the third supporting member along the optical axis direction, EP34 represents the distance from the image side face of the third supporting member to the object side face of the fourth supporting member along the optical axis direction, and L represents the distance from the lens barrel along the optical axis direction. direction, d1m represents the inner diameter of the image side surface of the first supporting member, d2s represents the inner diameter of the object side surface of the second supporting member, d2m represents the inner diameter of the image side surface of the second supporting member, d3s represents the inner diameter of the object side surface of the third supporting member, D2s represents the outer diameter of the object side surface of the second supporting member, D3s represents the outer diameter of the object side surface of the third supporting member, d0s represents the inner diameter of the object side end surface of the lens barrel, D4s represents the outer diameter of the object side surface of the fourth supporting member, D3m represents the outer diameter of the image side surface of the third supporting member, and d4s represents the inner diameter of the object side surface of the fourth supporting member.

[0042] A camera lens according to an exemplary embodiment of the present application includes a lens barrel, a lens assembly, and a support member assembly disposed within the lens barrel. The lens assembly may include six lenses having optical power, namely, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. The six lenses are arranged in sequence along the optical axis from the object side to the image side. Any two adjacent lenses among the first to sixth lenses may be spaced apart by a distance.

[0043] In an exemplary embodiment, the first lens may have a negative optical power, the second lens may have a positive or negative optical power, the third lens may have a positive optical power, the fourth lens may have a negative optical power, the fifth lens may have a positive optical power, and the sixth lens may have a negative optical power.

[0044] In an exemplary embodiment, the support member group may include a first support member disposed on the image side of the first lens and at least partially contacting the image side surface of the first lens, and a second support member disposed on the image side of the second lens and at least partially contacting the image side surface of the second lens.

[0045] In an exemplary embodiment, the support member group of the camera lens may include at least one of a first support member, a second support member, a third support member, a fourth support member, and a fifth support member. The first support member is disposed on the image side of the first lens and at least partially contacts the image side surface of the first lens. The second support member is disposed on the image side of the second lens and at least partially contacts the image side surface of the second lens. The third support member is disposed on the image side of the third lens and at least partially contacts the image side surface of the third lens. The fourth support member is disposed on the image side of the fourth lens and at least partially contacts the image side surface of the fourth lens. The fifth support member is disposed on the image side of the fifth lens and at least partially contacts the image side surface of the fifth lens. It should be understood that the number of support members is not specifically limited in this application. Any number of support members may be included between any two lenses, and any number of support members may also be included in the entire camera lens. The support members help the camera lens intercept redundant catadioptric light paths, reducing the generation of stray light and ghost images. Adding auxiliary supports between the support members and the lens barrel is beneficial to improving problems such as poor assembly stability and low performance yield caused by large step differences between lenses.

[0046] In an exemplary embodiment, the camera lens according to the present application may satisfy: 0.8 mm < f / tan(Semi-FOV) < 0.95 mm, where f is the effective focal length of the camera lens and Semi-FOV is the maximum semi-field angle of the camera lens. Reasonably controlling the ratio of the effective focal length of the camera lens to the tangent of the field angle ensures the effective focal length of the lens while ensuring the wide-angle characteristics of the lens, guaranteeing the imaging quality.

[0047] In an exemplary embodiment, the maximum semi-field angle Semi-FOV of the camera lens according to the present application is greater than 55°. Exemplarily, Semi-FOV may be in the range of 55° to 65°.

[0048] In an exemplary embodiment, the inner diameter of the object side or the image side of the second bearing member of the camera lens according to the present application is smaller than the inner diameter of each of the other bearing members in the bearing member group, and satisfies: 1.8 < (D2s - d2s) / d2m < 2.45, where D2s is the outer diameter of the object side of the second bearing member, d2s is the inner diameter of the object side of the second bearing member, and d2m is the inner diameter of the image side of the second bearing member. The inner diameter of the second bearing member is the minimum among all the bearing members, which is equivalent to the minimum light-transmitting area of the second lens among all the lenses. That is to say, the light passing aperture of the second lens controls the field angle of the lens within its specifications. At the same time, in order to ensure the machinability and bearing stability of the second bearing member and reduce the radial step difference, the ratio of the non-light-transmitting area to the light-transmitting area of the second lens is greater than 1.5.

[0049] In an exemplary embodiment, the camera lens according to the present application can satisfy: 30.8 < (T23 + CT3) / CP2 < 40.5 and 0.4 < EP12 / (T12 + CT2) < 0.75, where T23 represents the air gap between the second lens and the third lens on the optical axis, CT3 represents the central thickness of the third lens on the optical axis, CP2 represents the maximum thickness of the second bearing member along the optical axis direction, EP12 represents the distance along the optical axis from the image side of the first bearing member to the object side of the second bearing member, T12 represents the air gap between the first lens and the second lens on the optical axis, and CT2 represents the central thickness of the second lens on the optical axis. For the overall lens, the sensitivity of the focal length is relatively high at the second lens and the air gap adjacent to the second lens. When the above two conditional expressions are satisfied, the central thicknesses of the second lens and the third lens, the air gap between the second lens and the third lens on the optical axis, the maximum thickness of the second bearing member, the air gap between the first lens and the second lens on the optical axis, and the thickness of the non-light-transmitting area of the second lens (i.e., EP12) can be controlled. Among them, the central thickness and the thickness of the non-light-transmitting area of the second lens are reasonably set so that the second lens can stably bear against the front and rear lenses. The front and rear air gaps of the second lens and the thickness of the second bearing member are reasonably set to reduce the influence of the change in the lens gap on the focal length caused by reasons such as temperature or dropping, and thus stabilize the imaging quality.

[0050] The camera lens according to an exemplary embodiment of the present application is a six-piece wide-angle lens, including: a lens barrel, a lens group and a support member group disposed in the lens barrel. Among them, the lens group includes, in order from the object side to the image side along the optical axis: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. Among them, the first lens has a negative optical power, the second lens has an optical power, the third lens has a positive optical power, the fourth lens has a negative optical power, the fifth lens has a positive optical power, and the sixth lens has a negative optical power. The support member group includes: a first support member disposed on the image side of the first lens and at least partially contacting the image side surface of the first lens, and a second support member disposed on the image side of the second lens and at least partially contacting the image side surface of the second lens; the inner diameter of the object side surface or the image side surface of the second support member is smaller than the inner diameter of other support members in the support member group; the effective focal length f of the camera lens and the maximum semi-field angle Semi-FOV of the camera lens satisfy: 0.8mm < f / tan(Semi-FOV) < 0.95mm; the outer diameter D2s of the object side surface of the second support member, the inner diameter d2s of the object side surface of the second support member, and the inner diameter d2m of the image side surface of the second support member satisfy: 1.8 < (D2s - d2s) / d2m < 2.45; the air gap T23 between the second lens and the third lens on the optical axis, the central thickness CT3 of the third lens on the optical axis, and the maximum thickness CP2 of the second support member along the optical axis direction satisfy: 30.8 < (T23 + CT3) / CP2 < 40.5; the distance EP_{12} along the optical axis from the image side surface of the first support member to the object side surface of the second support member, the air gap T_{12} between the first lens and the second lens on the optical axis, and the central thickness CT2 of the second lens on the optical axis satisfy: 0.4 < EP_{12} / (T_{12} + CT2) < 0.75. By reasonably distributing the positive and negative optical powers of each lens, this camera lens is beneficial to controlling the light path, realizing the characteristics of wide angle and high resolution, can better meet the requirements of industry applications, and the camera lens satisfies: 0.8mm < f / tan(Semi-FOV) < 0.95mm, reasonably controlling the ratio of the effective focal length of the lens to the tangent of the field angle, ensuring the effective focal length of the lens while ensuring the wide-angle characteristics of the lens, and ensuring the imaging quality.The inner diameter of the second supporting member is the minimum among all the supporting members, which is equivalent to the minimum light-transmitting area of the second lens among all the lenses. That is to say, the light-transmitting aperture of the second lens controls the field angle of the lens within its specifications. At the same time, to ensure the machinability and supporting stability of the second supporting member and reduce the radial step difference, the ratio of the non-light-transmitting area to the light-transmitting area of the second lens is greater than 1.5. At the same time, considering that the sensitivity of the focal length is relatively high at the second lens and the air gap adjacent to the second lens, by reasonably controlling the central thicknesses of the second lens and the third lens, the air gap between the second lens and the third lens on the optical axis, the maximum thickness of the second supporting member, the air gap between the first lens and the second lens on the optical axis, and the thickness of the non-light-transmitting area of the second lens (i.e., EP12), the second lens can be stably supported by the front and rear lenses, and the influence of the change in the lens gap on the focal length caused by temperature or dropping can be reduced, thus stabilizing the imaging quality.

[0051] By controlling the conditional expressions 0.8mm < f / tan(Semi-FOV) < 0.95mm, 1.8 < (D2s - d2s) / d2m < 2.45, 30.8 < (T23 + CT3) / CP2 < 40.5, and 0.4 < EP12 / (T12 + CT2) < 0.75 within the range, the camera lens provided by the present application has good assembly stability while having the technical advantage of a wide angle, can balance or reduce the influence of the outside on the lens. In particular, considering that the sensitivity of the focal length is relatively high at the second lens and the air gap adjacent to the second lens, by satisfying the above conditional expressions, the second lens can be stably supported by the front and rear lenses, and the influence of the change in the lens gap on the focal length caused by temperature or dropping can be reduced, thus stabilizing the imaging quality and improving the MTF yield. The following combines Figures 2A to 2C , and further illustrates the role of the technical solution of the present application in improving the overall assembly stability of the lens and increasing the MTF yield. Figures 2A to 2C The defocus curves of the camera lens according to the present application in three cases when f = 1.34mm and Semi-FOV = 55.2° are shown.

[0052] Table 1-1 shows the sensitivities of the effective focal length F of the camera lens to CT1, CT2, CT3, T12, and T23 respectively. Among them, CT1, CT2, and CT3 respectively represent the central thicknesses of the first lens, the second lens, and the third lens, T12 represents the spatial gap between the first lens and the second lens on the optical axis, and T23 represents the spatial gap between the second lens and the third lens on the optical axis. In Table 1-1, the symbols "+" and "-" in +3μm and -3μm represent the fluctuation directions of the actual central thickness or air gap of the lens compared with the design values of the central thickness or air gap of the lens.

This indicates that when the values of (T23+CT3) / CP2 and EP12 / (T12+CT2) are both outside the control ranges of this application, overall assembly stability will be poor and the MTF yield during production will be low. For example, in Table 1-2, the central peak of the MTF curve in the 0.8T field of view is only 42.4%, with an offset of 13μm.

[0063] Table 1-4

[0064] The imaging lens according to an exemplary embodiment of the present application includes: a lens barrel, a lens group, and a support member group disposed in the lens barrel. Among them, the lens group includes, in order from the object side to the image side along the optical axis: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens. Among them, the first lens has a negative optical power, the second lens has an optical power, the third lens has a positive optical power, the fourth lens has a negative optical power, the fifth lens has a positive optical power, and the sixth lens has a negative optical power; the support member group includes: a first support member disposed on the image side of the first lens and at least partially contacting the image side surface of the first lens, a second support member disposed on the image side of the second lens and at least partially contacting the image side surface of the second lens, and a third support member disposed on the image side of the third lens and at least partially contacting the image side surface of the third lens; the inner diameter of the object side surface or the image side surface of the second support member is smaller than the inner diameter of other support members in the support member group; the effective focal length f of the imaging lens and the maximum semi-field angle Semi-FOV of the imaging lens satisfy: 0.8mm < f / tan(Semi-FOV) < 0.95mm; the central thickness CT3 of the third lens on the optical axis, the central thickness CT2 of the second lens on the optical axis, and the distance EP12 from the image side surface of the first support member to the object side surface of the second support member along the optical axis satisfy: 4.7mm -1 < CT3 / CT2 / EP12 < 6.95mm -1 ; the distance EP34 from the image side surface of the third support member to the object side surface of the fourth support member along the optical axis and the central thickness CT4 of the fourth lens on the optical axis satisfy: 1.42 < EP34 / CT4 < x.6. This imaging lens is a six-piece lens. By reasonably setting the optical power of each lens and controlling the ratio of f / tan(Semi-FOV) within the range of 0.7mm to 1.0mm, the wide-angle characteristics and imaging quality of the lens can be ensured. Among all the support members, the inner diameter of the second support member is the smallest, that is, the radius of the light-transmitting area of the second lens is the smallest, and the structural part of the second lens needs to be increased to support on the first lens. Under the condition of 4.7mm -1 < CT3 / CT2 / EP12 < 6.95mm-1 Within the range, it can ensure the thickness ratio and the outer diameter to middle thickness ratio of the second lens, reduce the risk of welding marks during lens molding and the risk of deformation during lens demolding, and improve the lens quality. At the same time, considering the lens sensitivity, a relatively large air gap is left behind the third lens. This gap requires adding an injection molding support piece with a certain thickness between the third lens and the fourth lens. Therefore, when 1.42 < EP34 / CT4 < 2.6 is satisfied, it can ensure that the thickness of the injection molding support piece is large enough to ensure complete molding, and at the same time ensure that the wall thickness of the structural part of the fourth lens is large enough, control the thickness ratio of the lens within a reasonable range, and reduce the risk of poor appearance problems during lens molding.

[0065] In an exemplary embodiment, the camera lens according to the present application can satisfy: 6.3 < CT2 / (CP1 + CP2) < 9.4, where CT2 is the central thickness of the second lens on the optical axis, CP1 is the maximum thickness of the first support piece along the optical axis direction, and CP2 is the maximum thickness of the second support piece along the optical axis direction. The shape of the effective light passing aperture part of the second lens is thick in the middle and thin at both ends. Satisfying 6.3 < CT2 / (CP1 + CP2) < 9.4 is beneficial to ensuring the uniformity of the overall shape of the second lens, making the wavefront speeds of the colloid in all directions balanced during the injection molding process, reducing the quality risks such as flow marks and weld lines during the injection molding of the second lens, and improving the yield of the production of the second lens.

[0066] In an exemplary embodiment, the camera lens according to the present application can satisfy: 0.7mm < D2s / d2s × CT2 < 1.2mm, where D2s is the outer diameter of the object side of the second support piece, d2s is the inner diameter of the object side of the second support piece, and CT2 is the central thickness of the second lens on the optical axis. The second support piece plays the most important role in blocking light in the system. When 0.7mm < D2s / d2s × CT2 < 1.2mm is satisfied, it can effectively intercept the ineffective light rays hitting from the first lens and the second lens, and at the same time ensure that the effective light rays of the lens are not blocked.

[0067] In an exemplary embodiment, the camera lens according to the present application can satisfy: -0.05 < (EP01 - CT1) / T12 < 0.85, where EP01 is the distance along the optical axis from the object-side end face of the lens barrel to the object-side surface of the first bearing member, CT1 is the central thickness of the first lens on the optical axis, and T12 is the air gap between the first lens and the second lens on the optical axis. Due to the space limitation of the terminal assembly, sufficient space needs to be reserved from the object-side end face of the lens barrel to the object-side surface of the first bearing member (i.e., EP01 needs to be large enough) to ensure that the first lens does not touch the fitting on the object side of the lens barrel in most impact cases. At the same time, T12 limits that EP01 cannot be too large, otherwise the wall thickness of the structural part of the first lens will be too thin, resulting in poor molding and affecting the lens quality. When -0.05 < (EP01 - CT1) / T12 < 0.85 is satisfied, both the stability of the lens under physical collision and the molding yield of the first lens are ensured.

[0068] In an exemplary embodiment, the camera lens according to the present application can satisfy: 1.42 < EP34 / CT4 < 2.6, where EP34 is the distance along the optical axis from the image-side surface of the third bearing member to the object-side surface of the fourth bearing member, and CT4 is the central thickness of the fourth lens on the optical axis. Considering the sensitivity of the lens, a large air gap is left behind the third lens. At this time, the gap requires an injection-molded bearing member with a certain thickness to be added between the third lens and the fourth lens. When 1.42 < EP34 / CT4 < 2.6 is satisfied, it can ensure that the thickness of the injection-molded bearing member is large enough to ensure complete molding, and at the same time, it can also ensure that the wall thickness of the structural part of the fourth lens is large enough to control the thickness ratio of the lens within a reasonable range, reducing the risk of poor appearance problems during lens molding.

[0069] In an exemplary embodiment, the camera lens according to the present application can satisfy: 0.95 < EP01 / CT1 < 1.75, where EP01 is the distance along the optical axis from the object-side end face of the lens barrel to the object-side surface of the first bearing member, and CT1 is the central thickness of the first lens on the optical axis. Considering the stability of the lens in physical collision experiments, the wall thickness of the lens barrel where the first lens is supported must ensure a certain strength. When 0.95 < EP01 / CT1 < 1.75 is satisfied, it can ensure that while reducing the wall thickness of the structural part of the first lens to leave the wall thickness of the lens barrel, the thickness ratio of the first lens is reasonably controlled, which can not only meet the basic strength requirements of the lens but also improve the accuracy of the surface shape and PV value during lens injection molding, thereby improving the molding yield of the first lens.

[0070] In an exemplary embodiment, the camera lens according to the present application can satisfy: 2.7 < TD / (EP23 + EP34) < 4.4, where TD is the distance on the optical axis from the object side surface of the first lens to the image side surface of the sixth lens, EP23 is the distance along the optical axis from the image side surface of the second bearing member to the object side surface of the third bearing member, and EP34 is the distance along the optical axis from the image side surface of the third bearing member to the object side surface of the fourth bearing member. When 2.7 < TD / (EP23 + EP34) < 4.4 is satisfied, it is beneficial to flexibly select an injection-molded bearing member or a pressed bearing member according to the different center thicknesses of the fourth lens, which can not only ensure the molding yield of the lens but also reduce the cost of the bearing member.

[0071] In an exemplary embodiment, the camera lens according to the present application can satisfy: -1.05 < (D4s - D3m) / (D2s - D3s) < 2.95, where D4s is the outer diameter of the object side surface of the fourth bearing member, D3m is the outer diameter of the image side surface of the third bearing member, D2s is the outer diameter of the object side surface of the second bearing member, and D3s is the outer diameter of the object side surface of the third bearing member. When -1.05 < (D4s - D3m) / (D2s - D3s) < 2.95 is satisfied, it can ensure that the connection line of the outermost bearing points of the second lens to the fifth lens is close to the same height, and when applying the assembly pressure, the pressure can be transmitted to the object side of the lens barrel through the structural part of the lens with higher efficiency, thereby reducing the deformation of the effective diameter area of the lens and reducing the influence of the assembly process on the lens surface shape, and thus improving the assembly yield.

[0072] In an exemplary embodiment, the camera lens according to the present application can satisfy: 2.0 < f3 / d3s × N3 < 3.15, where f3 is the effective focal length of the third lens, d3s is the inner diameter of the object side surface of the third bearing member, and N3 is the refractive index of the third lens. The light is divergent after passing through the third lens, and the air gap behind the third lens is relatively large, so the light emitted by the third lens is more likely to diverge into the non-effective diameter area of the fourth lens, resulting in too much interfering light and forming stray light. When 2.0 < f3 / d3s × N3 < 3.15 is satisfied, the third bearing member can block the ineffective light passing through the third lens to the greatest extent, and at the same time block the light hitting the non-effective diameter area of the fourth lens, reducing the risk of subsequent stray light generation and improving the imaging quality of the lens.

[0073] In an exemplary embodiment, the camera lens according to the present application may satisfy: -1.8 < f1 / d0s < -0.7, where f1 is the effective focal length of the first lens, and d0s is the inner diameter of the object-side end face of the lens barrel. d0s represents the aperture of the first diaphragm of the entire system. When -1.8 < f1 / d0s < -0.7 is satisfied, not only can non-effective light hitting the first lens structure part from the outside be blocked, but also the structure part of the first lens can be shielded from the line of sight on the object side, ensuring a good appearance performance in the case of the whole machine, and at the same time ensuring that effective light passes through the first lens.

[0074] In an exemplary embodiment, the camera lens according to the present application may satisfy: -1.0 < f3 / f4 < -0.6 and 0.62 < d3s / d4s < 0.81, where f3 is the effective focal length of the third lens, f4 is the effective focal length of the fourth lens, d3s is the inner diameter of the object-side surface of the third support member, and d4s is the inner diameter of the object-side surface of the fourth support member. The third lens and the fourth lens are located in the middle section of the camera lens. Reasonably setting their effective focal lengths and satisfying -1.0 < f3 / f4 < -0.6 plays an important role in diverging light for meeting the wide-angle characteristics of the lens. After the light is diverged, the marginal light is likely to hit the lens structure area and generate extra stray light. When 0.62 < d3s / d4s < 0.81, the reasonable setting of the inner diameters of the third support member and the fourth support member can effectively block the extra marginal light.

[0075] In an exemplary embodiment, the camera lens according to the present application may satisfy: 4.7 mm -1 <CT3 / CT2 / EP12 < 6.95 mm -1 , where CT3 is the central thickness of the third lens on the optical axis, CT2 is the central thickness of the second lens on the optical axis, and EP12 is the distance along the optical axis from the image-side surface of the first support member to the object-side surface of the second support member. The second lens abuts against the third lens. When 4.7 mm -1 <CT3 / CT2 / EP12 < 6.95 mm -1 is satisfied, ensuring that the relevant thickness ratio is within a reasonable range, which can ensure the thickness ratio of the second lens and the medium thickness ratio of the outer diameter part, reduce the risk of welding marks during lens molding, and the deformation risk during lens demolding, and improve the lens quality.

[0076] In an exemplary embodiment, the camera lens according to the present application can satisfy: 0.1 mm < f23 / T23 × CP2 < 0.3 mm, where f23 is the combined focal length of the second lens and the third lens, T23 is the air gap between the second lens and the third lens on the optical axis, and CP2 is the maximum thickness of the second bearing member along the optical axis direction. By controlling T23 and f23, the central thicknesses of the second lens and the third lens are indirectly controlled. When 0.1 mm < f23 / T23 × CP2 < 0.3 mm, it is beneficial to ensure the molding requirements of the lens and the front-back uniformity. The central thicknesses of the second lens and the third lens on the optical axis and CP2 affect the difficulty of molding the second lens. By controlling this conditional expression, it helps to improve the lens thickness uniformity of the second lens and the third lens, making the lens easier to mold.

[0077] In an exemplary embodiment, the camera lens according to the present application can satisfy: 0.3 < |(SG22 + SG31) / T23| < 1.5, where SG22 is the distance along the optical axis from the intersection of the image side of the second lens and the optical axis to the object side of the second bearing member (as Figure 9 shown), SG31 is the distance along the optical axis from the intersection of the object side of the third lens and the optical axis to the image side of the second bearing member (as Figure 9 shown), and T23 is the air gap between the second lens and the third lens on the optical axis. Satisfying 0.3 < |(SG22 + SG31) / T23| < 1.5, the control of the ratio of the sum value of the distance along the optical axis from the intersection of the image side of the second lens and the optical axis to the object side of the second bearing member and the distance along the optical axis from the intersection of the object side of the third lens and the optical axis to the image side of the second bearing member to the air gap between the second lens and the third lens on the optical axis is beneficial to controlling the surface shapes of the lenses on both sides of the air gap between the second lens and the third lens on the optical axis, and reducing the sensitivity of the surface shapes on both sides to field curvature.

[0078] In an exemplary embodiment, the camera lens according to the present application can satisfy: 3.55 < (|R6| + |R7|) / d3s < 7.75, where R6 is the radius of curvature of the image side of the third lens, R7 is the radius of curvature of the object side of the fourth lens, and d3s is the inner diameter of the object side of the third bearing member. Satisfying 3.55 < (|R6| + |R7|) / d3s < 7.75 is beneficial to reducing the generation of stray light in the camera lens. The radius of curvature of the image side of the third lens and the radius of curvature of the object side of the fourth lens determine the surface shape trends of the third lens and the fourth lens, and at the same time affect the shape of the third bearing member and the size of the inner diameter of the object side. In the conditional expression 3.55 < (|R6| + |R7|) / d3s < 7.75, the third bearing member can not only block the divergent light coming from the third lens, but also reduce the ineffective light reflected by itself and the fourth lens, improving the lens quality.

[0079] In an embodiment of the present application, at least one of the mirror surfaces of each lens is an aspherical mirror surface, that is, at least one of the mirror surfaces from the object side surface of the first lens to the image side surface of the sixth lens is an aspherical mirror surface. The characteristic of an aspherical lens is that the curvature changes continuously from the center of the lens to the periphery of the lens. Unlike a spherical lens with a constant curvature from the center of the lens to the periphery of the lens, an aspherical lens has a better curvature radius characteristic, and has the advantages of improving distortion aberration and improving astigmatism aberration. After adopting an aspherical lens, the aberration that occurs during imaging can be eliminated as much as possible, thereby improving the imaging quality. Optionally, the object side surface and the image side surface of all lenses from the first lens to the sixth lens are aspherical mirror surfaces.

[0080] In an exemplary embodiment, the camera lens may further include a filter for correcting color deviation and / or a protective glass for protecting a photosensitive element located on the imaging surface.

[0081] The camera lens according to the above-described embodiment of the present application can utilize multiple lenses, such as the six lenses described above. By rationally allocating the optical power, surface shape, and arrangement of the supporting members of each lens, the span of each gear of the lens and the lens barrel is made more uniform, thereby enhancing the ability to converge light and improving the imaging quality of wide-angle, large-image-area camera lenses. However, those skilled in the art will understand that, without departing from the technical solutions claimed in this application, the number of lenses constituting the camera lens can be changed to achieve the various results and advantages described in this specification. For example, although six lenses are described as an example in the embodiments, the camera lens is not limited to including six lenses. If desired, the camera lens may also include other numbers of lenses.

[0082] The following further describes specific embodiments of the camera lens applicable to the above-mentioned embodiments with reference to the accompanying drawings. Figures 3A to 4C Describe the camera lenses 1001 and 1002 according to embodiments 1 and 2 of the present application; refer to Figures 5A to 6C Describe the camera lenses 2001 and 2002 according to embodiments 3 and 4 of the present application; refer to 7A to 8C The imaging lenses 3001 and 3002 according to Embodiments 5 and 6 of the present application are described.

[0083] Example 1

[0084] Figure 3A FIG. 1 shows a schematic structural diagram of a camera lens 1001 according to Embodiment 1 of the present application. Figure 3A As shown, the camera lens 1001 includes a lens barrel P0, lens groups E1 to E6, and support member groups P1 to P5. The camera lens 1001 also includes an aperture stop STO (not shown) disposed between the second lens and the third lens.

[0085] like Figure 3A As shown, the lens group of the camera lens 1001 includes, from the object side to the image side, a first lens E1, a second lens E2, a third lens E3, a fourth lens E4, a fifth lens E5, and a sixth lens E6. The first lens E1 has an object-side surface S1 and an image-side surface S2. The second lens E2 has an object-side surface S3 and an image-side surface S4. The third lens E3 has an object-side surface S5 and an image-side surface S6. The fourth lens E4 has an object-side surface S7 and an image-side surface S8. The fifth lens E5 has an object-side surface S9 and an image-side surface S10. The sixth lens E6 has an object-side surface S11 and an image-side surface S12. The camera lens 1001 also includes a filter (not shown) for correcting chromatic aberration, the filter having an object-side surface S13 and an image-side surface S14. Light from an object sequentially passes through each surface S1 to S14 and is ultimately imaged on an imaging surface S15 (not shown).
