[0025] It should be noted that the embodiments and features in the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0026] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0027] In the present application, unless otherwise specified, the orientation words such as "upper, lower, top, bottom" are generally directed to the directions shown in the drawings, or are directed to the vertical, perpendicular or gravity directions of the components themselves; similarly, for the convenience of understanding and description, "inner, outer" refers to the inner and outer relative to the contour of each component, but the above orientation words are not used to limit the present application.

[0028] In order to solve the problem that miniaturization and high-precision assembly of the optical lens in the prior art are difficult to be considered, the present application provides an optical lens.

[0029] As shown in Figures 1 to 5 The optical lens includes a bearing lens 10 and a spacer ring 20. The object side of the bearing lens 10, or the image side of the bearing lens 10, or both the object side and the image side of the bearing lens 10 are spherical surfaces, and the spherical surfaces are connected with the outer annular surface of the bearing lens 10. The spacer ring 20 has a bearing end 24, and the bearing end 24 has a first annular surface 21, a bearing annular surface 22 and a second annular surface 23 connected in sequence in the direction close to the optical axis of the optical lens. The bearing annular surface 22 is inclined relative to the optical axis, and at least a part of the bearing annular surface 22 is in contact with the spherical surface.

[0030] In the optical lens, at least one of the object side or the image side of the bearing lens 10 is a spherical surface, and the spherical surface is connected with the outer annular surface of the bearing lens 10, so that the effective light transmission area of the spherical surface extends to the outer annular surface of the bearing lens 10. By retaining a larger effective light transmission area of the spherical surface, the area of the optical effective surface is increased, thereby improving the light flux and imaging quality of the optical lens. The spherical surface of the bearing lens 10 and the bearing end 24 of the spacer 20 are in mutual bearing, wherein the bearing end 24 of the spacer 20 is sequentially connected with the first annular surface 21, the bearing annular surface 22 and the second annular surface 23 in the direction close to the optical axis of the optical lens. The bearing annular surface 22 is an annular inclined surface arranged obliquely relative to the optical axis, and directly contacts the spherical surface to realize the mutual bearing of the bearing lens 10 and the spacer 20. Compared with the flange plane bearing method in the prior art, the cooperation mode of the spherical surface and the bearing annular surface 22 of the present application realizes bearing and reduces the space occupation between the bearing lens 10 and the spacer 20, so that the optical lens can be designed more compactly, which is beneficial to the miniaturization and light weight of the optical lens. The first annular surface 21 is arranged away from the optical axis relative to the bearing annular surface 22, which is beneficial to control the relative size of the bearing annular surface 22, reduce the forming burr, and improve the assembly stability. The second annular surface 23 gradually moves away from the bearing lens 10 while extending away from the bearing annular surface 22, which fully utilizes the space while ensuring the contact stability of the bearing and the accuracy of the position of the bearing lens 10, avoids the burr of the inner annular surface of the spacer 20, and reduces the performance abnormalities and stray light ghost image risk caused by unstable assembly.

[0031] As shown in Figures 1 to 5 The angle A between the extension direction of the bearing annular surface 22 and the direction perpendicular to the optical axis satisfies: 30°≤A≤44°. If the angle A is too small, the bearing annular surface 22 is too flat and closer to the flange plane in the prior art, and the bearing tightness in the direction perpendicular to the optical axis will be reduced. If the angle A is too large, it is not conducive to the full contact of the bearing annular surface 22 and the bearing lens 10, and it will also increase the processing difficulty of the bearing lens 10, leading to cost increase. By limiting 30°≤A≤44°, the inclination angle of the bearing annular surface 22 is limited, which can ensure that the effective cooperation length of the bearing annular surface 22 and the spherical surface after tangency at one end of the bearing annular surface 22 is more reasonable, can provide a wider bearing range for the bearing lens 10 and the spacer 20, and further optimize the position of the bearing lens 10 in the optical lens, which is beneficial to improve the stability of the bearing lens 10, prevent displacement or vibration of the bearing lens 10 during assembly and use, and maintain good optical alignment of the optical lens.

[0032] As shown in Figures 1 to 5As shown, the spherical surface has a contact portion in contact with the bearing annular surface 22, and the included angle B between the extension direction of the tangent line of the contact portion and the direction perpendicular to the optical axis satisfies: 30°≤B≤44°. By limiting 30°≤B≤44°, the machinability of the spherical surface can be improved, and at the same time, the cooperation between the bearing lens 10 and the spacer 20 is more compact, avoiding assembly errors caused by too large or too small included angle B, which leads to the decline of the performance of the optical lens. When the extension direction of the bearing annular surface 22 and the extension direction of the tangent line of the contact portion form a proper included angle, the contact area between the bearing lens 10 and the spacer 20 can be ensured to be appropriate, which ensures the stability of the bearing while making the inside of the optical lens more compact, which is beneficial to the miniaturization of the optical lens.

[0033] Preferably, the extension direction of the bearing annular surface 22 is parallel to the extension direction of the tangent line of the contact portion. This arrangement is beneficial to providing an accurate contact angle when the bearing lens 10 and the spacer 20 are assembled, ensuring the stable positioning of the bearing lens 10 on the bearing annular surface 22, and reducing the optical performance fluctuations and stray light ghosting risks caused by unstable bearing.

[0034] As shown, Figures 1 to 5 The annular width C of the bearing annular surface 22 satisfies: 0.14mm≤C≤0.26mm. By limiting 0.14mm≤C≤0.26mm, within this range, the wider the annular width of the bearing annular surface 22, the larger the area that can be cooperated between the bearing annular surface 22 and the spherical surface of the bearing lens 10, and the bearing strength and stability provided are also enhanced accordingly, avoiding the complexity of processing and size increase caused by the too large contact area of the annular width C of the bearing annular surface 22, and also avoiding the unstable bearing or poor contact caused by the displacement of the bearing lens 10 caused by the too small annular width C of the bearing annular surface 22.

[0035] As shown, Figures 1 to 5 In the direction close to the optical axis, the second annular surface 23 extends away from the spherical surface, and the included angle F between the extension direction of the second annular surface 23 and the extension direction of the bearing annular surface 22 satisfies: 50°≤F≤68°. By limiting 50°≤F≤68°, it can be avoided that the spacer 20 leaves burrs on the bearing annular surface 22 and the inner annular surface of the spacer 20 during the production process, ensuring that the bearing annular surface 22 has enough flatness, avoiding that the burrs higher than the bearing annular surface 22 destroy the assembly stability, and avoiding affecting the bearing between the bearing lens 10 and the spacer 20. In addition, burrs of different heights will affect the propagation of light, causing unnecessary scattering or reflection, leading to the decline of imaging quality, and optical interference phenomena such as stray light or ghosting. By controlling the included angle F, the optical consistency of the bearing end 24 is ensured, and potential optical interference is reduced, improving the optical performance of the optical lens.

[0036] As shown, Figures 1 to 5As shown, the ring belt width D of the second annular surface 23 satisfies: 0.03mm≤D≤0.16mm. If the width of the second annular surface 23 is too small, it will lead to high processing difficulty and cannot avoid burr generation, thereby affecting the stable support between the supported lens 10 and the spacer ring 20, and causing fluctuations in optical performance. If the width of the second annular surface 23 is too large, it will increase the volume and weight of the spacer ring 20, which is not conducive to the miniaturization design of the optical lens. By limiting 0.03mm≤D≤0.16mm, the interference of the spacer ring 20 to the light path can be minimized, the high light flux and good imaging quality can be maintained, and it can also ensure that the burr inside the spacer ring 20 is fully covered to avoid the burr affecting the assembly stability.

[0037] As shown, Figures 1 to 5 The ring belt width E of the first annular surface 21 satisfies: 0.10mm≤E≤0.17mm. On the automatic production line, the spacer ring 20 needs to be accurately positioned and placed in the feeding tray to facilitate subsequent assembly operations. If the ring belt width E of the first annular surface 21 is not properly set, the length of the supporting annular surface 22 is too long and the flatness is reduced, the spacer ring 20 will be unstable in the feeding tray and is easy to shift or overturn, affecting the smooth progress of the assembly process. By limiting 0.10mm≤E≤0.17mm, the stability of the spacer ring 20 when placed in the feeding tray can be ensured, the assembly error can be reduced, and the production efficiency can be improved.

[0038] Optionally, from the end of the second annular surface 23 close to the supporting annular surface 22 to the end of the second annular surface 23 away from the supporting annular surface 22, the second annular surface 23 is inclined away from the optical axis. That is, from the connection between the second annular surface 23 and the supporting annular surface 22 as the starting point, the second annular surface 23 gradually moves away from the optical axis, which is beneficial to increase the light aperture of the optical lens, and can also reduce the size of the supporting end 24 of the spacer ring 20, which is beneficial to save the internal space and weight of the optical lens, and further helps the miniaturization of the optical lens.

[0039] As shown, Figures 1 to 5As shown, the optical lens further comprises a lens barrel 30, the abutting lens 10 and the spacer 20 are contained in the lens barrel 30, at least a part of the spacer 20 directly abuts against the inner wall surface of the lens barrel 30, and the abutting end 24 of the spacer 20 is spaced apart from the inner wall surface of the lens barrel 30. The lens barrel 30 is used for containing and fixing the abutting lens 10 and the spacer 20, at least a part of the outer annular surface of the spacer 20 directly abuts against the inner wall surface of the lens barrel 30 to form a stable contact, thereby ensuring that the spacer 20 is correctly positioned in the lens barrel 30 and is stably supported. The abutting end 24 of the spacer 20 is not in direct contact with the lens barrel 30, but is spaced apart from the inner wall surface of the lens barrel 30, thereby avoiding that the abutting end 24 is directly stressed by the lens barrel 30 and affecting the abutting stability of the abutting lens 10, and reducing the friction and displacement between the abutting lens 10 and the inner wall surface of the lens barrel 30, thereby avoiding that the direct contact destroys the support balance of the abutting lens 10 and the spacer 20.

[0040] It should be noted that when the optical lens is assembled on site, the lens barrel 30, the abutting lens 10 and the spacer 20 are sequentially assembled, the spacer 20 is matched with the spherical surface of the abutting lens 10 by the abutting annular surface 22 of the spacer 20, thereby realizing the assembly of the abutting lens 10 and the spacer 20.

[0041] Embodiment One

[0042] As shown in the drawings, Figure 3 The optical lens of the embodiment one of the present application is described. In the embodiment, the optical lens at least comprises an abutting lens 10, a spacer 20 and a lens barrel 30. In the embodiment, the image side surface of the abutting lens 10 is a spherical surface. The specific size of the optical lens of the embodiment one is shown in Table 1.

[0044] Example / Parameter A(°) B(°) C (mm) D (mm) E (mm) F(°) Example One 40 40 0.17 0.03 0.17 50°

[0045] As shown in Table 1, the included angle A between the extending direction of the abutting annular surface 22 and the direction perpendicular to the optical axis is small, which is beneficial to maintaining the stability of the optical lens. The annular width C of the abutting annular surface 22 can meet the requirement of the stability of the optical lens. The annular width D of the second annular surface 23 is small, which improves the tightness of the abutting of the abutting lens 10 and the spacer 20. The annular width E of the first annular surface 21 ensures the stability of the optical lens during assembly, and the included angle F between the extending direction of the second annular surface 23 and the extending direction of the abutting annular surface 22 ensures the flatness of the abutting annular surface 22.

[0046] Embodiment Two

[0047] As shown in the drawings, Figure 4The image shown illustrates an optical lens according to Embodiment 2 of this application. In this embodiment, the optical lens includes at least a supporting lens 10, a spacer 20, and a lens barrel 30. In this embodiment, the image-side surface of the supporting lens 10 is spherical. The difference from Embodiment 1 lies in the values ​​of the parameters of the supporting lens 10 and the spacer 20. The specific dimensions of the optical lens of Embodiment 2 are shown in Table 2.

[0048] Table 2

[0049] Example / Parameter A(°) B(°) C (mm) D (mm) E (mm) F(°) Example Two 44 44 0.14 0.07 0.15 58

[0050] As shown in Table 2, the optical lens of Embodiment 2 has an angle A between the extension direction of the bearing ring 22 and the direction perpendicular to the optical axis, making the bearing of the spacer 20 more stable. The narrow band width C of the bearing ring 22 is small, which is beneficial for miniaturization of the optical lens. The band width D of the second ring 23 can effectively reduce the negative impact of burrs, the band width E of the first ring 21 further improves the stability of the optical lens during assembly, and the angle F between the extension direction of the second ring 23 and the extension direction of the bearing ring 22 ensures that the burrs produced during processing do not exceed the bearing ring 22.

[0051] Example 3

[0052] like Figure 5 The image shown illustrates an optical lens according to Embodiment 3 of this application. In this embodiment, the optical lens includes at least a supporting lens 10, a spacer 20, and a lens barrel 30. In this embodiment, the image-side surface of the supporting lens 10 is spherical. The difference from Embodiment 1 lies in the values ​​of the parameters of the supporting lens 10 and the spacer 20. The specific dimensions of the optical lens of Embodiment 3 are shown in Table 3.

[0053] Table 3

[0054]

[0055] As shown in Table 3, the optical lens of Embodiment 3 has a smaller angle A between the extension direction of the bearing ring 22 and the direction perpendicular to the optical axis, effectively saving assembly space. The ring width C of the bearing ring 22 is relatively large, which can meet the higher stability requirements of the optical lens. The ring width D of the second ring 23 is relatively large, which pays more attention to avoiding the generation of burrs and sharp edges. The smaller ring width E of the first ring 21 saves space without affecting the flatness, and the angle F between the extension direction of the second ring 23 and the extension direction of the bearing ring 22 further ensures the flatness of the bearing ring 22.

[0056] Example 4

[0057] In a specific embodiment not shown, the difference from Embodiment 1 is that the object side of the supporting lens 10 is spherical, and the spacer 20 rests on the object side of the supporting lens 10.

[0058] Embodiment five

[0059] In one embodiment not shown, the difference from embodiment one is that the object side and the image side of the bearing lens 10 are both spherical surfaces, and the object side and the image side of the bearing lens 10 are each provided with a bearing ring 20.

[0060] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects:

[0061] 1. In the optical lens of the present application, at least one of the object side or the image side of the bearing lens 10 is a spherical surface, and the spherical surface is connected to the outer annular surface of the bearing lens 10, so that the effective light transmission area of the spherical surface extends to the outer annular surface of the bearing lens 10. By retaining a larger effective light transmission area of the spherical surface, the optical effective surface area is increased, thereby improving the luminous flux and imaging quality of the optical lens. The spherical surface of the bearing lens 10 and the bearing end 24 of the bearing ring 20 are mutually supported, wherein the bearing end 24 of the bearing ring 20 is sequentially connected to the first annular surface 21, the bearing annular surface 22 and the second annular surface 23 in the direction close to the optical axis of the optical lens.

[0062] 2. The bearing annular surface 22 is an annular inclined surface arranged obliquely relative to the optical axis, and directly contacts the spherical surface to realize the mutual support of the bearing lens 10 and the bearing ring 20. Compared with the flange plane bearing method in the prior art, the cooperation mode of the spherical surface and the bearing annular surface 22 of the present application realizes bearing and reduces the space occupation between the bearing lens 10 and the bearing ring 20, so that the optical lens can be designed more compactly, which is beneficial to the miniaturization and light weight of the optical lens.

[0063] 3. The first annular surface 21 is arranged away from the optical axis relative to the bearing annular surface 22, which is beneficial to controlling the relative size of the bearing annular surface 22, reducing the forming burr and improving the assembly stability. The second annular surface 23 gradually moves away from the bearing lens 10 while extending away from the bearing annular surface 22, which fully utilizes the space while ensuring the contact stability of the bearing and the accuracy of the position of the bearing lens 10, avoids the generation of burrs on the inner annular surface of the bearing ring 20, and reduces the performance abnormalities and stray light ghost image risks caused by unstable assembly.
