Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of optical equipment imaging, and in particular to a lens barrel, an optical imaging lens, and an electronic device. Background Art
[0002] Currently, in general imaging lens systems, in addition to the primary imaging lens, an annular optical element is typically placed between the lenses to ensure proper optical spacing between them. However, when other optical elements, such as light shielding plates, are required, these plates can only be placed on either side of the annular optical element and between the adjacent lenses. Consequently, existing manufacturing and assembly techniques make it difficult to adjust the light shielding plates to the appropriate position relative to the optical axis.
[0003] Furthermore, existing annular optical elements are typically manufactured using injection molding, resulting in a smooth, bright surface with high reflectivity. This ineffectively attenuates the intensity of stray light incident on the annular optical element, causing it to reflect onto the imaging surface and thus affect image quality. Therefore, improving the structure of the annular optical element and the light shielding plate, allowing the light shielding plate to be adjusted and positioned appropriately, and reducing stray light reflection from the annular optical element has become one of the most important issues today.
[0004] In addition, for traditional lenses, multiple lenses are assembled in the same lens barrel, and the relative positions between the lenses are basically fixed and cannot be adjusted. Once the lenses are assembled in the lens barrel, the quality of the lenses is determined, which also makes the processing accuracy requirements for the lens barrel and lenses higher. It is worth mentioning that for lenses with a small number of lenses, the impact of lens assembly errors is relatively small, so the overall lens may have greater advantages in production and module assembly. However, when the number of lenses increases, the more lenses there are, the more serious the problems caused by the lenses, so the improvement of the lenses is more urgent. Therefore, how to ensure good imaging quality and yield in the production process while providing high pixels through multiple lenses is an important aspect that needs to be studied.
[0005] The lens element and the assembly relationship between the lens and the lens barrel directly affect the quality of the lens. For optical modules, especially those used in some smart devices such as smartphones, their size is relatively small. Therefore, how to combine existing equipment requirements, make full use of the lens structure, and research lenses suitable for actual production applications are also aspects that need to be considered.
[0006] In other words, in the prior art optical imaging lens, there is a problem that it is difficult to adjust the light shielding plate to an appropriate position. Summary of the Invention

[0033] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0034] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.
[0035] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.
[0036] In order to solve the problem in the prior art that it is difficult to adjust a light shielding plate of an optical imaging lens to an appropriate position, the present invention provides a lens barrel, an optical imaging lens and an electronic device.
[0037] like Figures 1 to 6 As shown, the lens barrel includes a first lens barrel 10, a second lens barrel 30 and a shading element 50. The object side end of the first lens barrel 10 has a first connecting structure 20; the image side end of the second lens barrel 30 has a second connecting structure 40 that cooperates with the first connecting structure 20; the shading element 50 is arranged between the first connecting structure 20 and the second connecting structure 40.
[0038] By arranging the shading element 50 between the first connecting structure 20 and the second connecting structure 40, the position of the shading element 50 is fixed, and the position of the shading element 50 is not affected when the lens is assembled in the lens barrel. Because the first lens barrel 10 and the second lens barrel 30 are separate, the position between the first connecting structure 20 and the second connecting structure 40 can be adjusted, thereby facilitating the adjustment of the position of the shading element 50 to an appropriate position. In addition, the separation of the first lens barrel 10 and the second lens barrel 30 also facilitates adjustment of the position of the lens.
[0039] Example 1
[0040] like Figure 2 and Figure 3As shown, the first connecting structure 20 includes a first outer supporting surface 21, a first axial connecting surface 22 and a first inner supporting surface 23 connected in sequence in the direction close to the optical axis 60 of the lens barrel, and the first inner supporting surface 23 is close to the image side end of the first lens barrel 10 relative to the first outer supporting surface 21; the second connecting structure 40 includes a second outer supporting surface 41, a second axial connecting surface 42 and a second inner supporting surface 43 connected in sequence in the direction close to the optical axis 60, and the second outer supporting surface 41 is close to the object side end of the second lens barrel 30 relative to the second inner supporting surface 43; wherein, after the first connecting structure 20 is connected to the second connecting structure 40, the first axial connecting surface 22 and the second axial connecting surface 42 are abutted or spaced apart, the first inner supporting surface 23 and the second inner supporting surface 43 are spaced apart to form a first interval, and the shading element 50 is arranged at the first interval. When the first axial connecting surface 22 and the second axial connecting surface 42 are in contact, the first connecting structure 20 and the second connecting structure 40 are in a true snap fit, and when the first axial connecting surface 22 and the second axial connecting surface 42 are spaced apart, the first connecting structure 20 and the second connecting structure 40 are in a false snap fit. The first axial connecting surface 22 and the second axial connecting surface 42 can be connected by glue to connect the first lens barrel 10 and the second lens barrel 30. The first inner supporting surface 23 and the second inner supporting surface 43 are spaced apart to allow the light shielding element 50 to be disposed between the first inner supporting surface 23 and the second inner supporting surface 43, and the light shielding element 50 bears against the first inner supporting surface 23 or the second inner supporting surface 43 to provide support for the light shielding element 50.
[0041] When the first axial connecting surface 22 and the second axial connecting surface 42 are spaced apart, the distance a between the first axial connecting surface 22 and the second axial connecting surface 42 is greater than 0 and less than or equal to 0.02 mm. This arrangement facilitates adjustment of the position of the light shielding element 50 so that the central hole of the light shielding element 50 is aligned with the central hole of the lens barrel, thereby preventing the light shielding element 50 from blocking the light used for imaging.
[0042] like Figure 2 As shown, a second gap is formed between the first outer supporting surface 21 and the second outer supporting surface 41, and the second gap is used to accommodate glue. This arrangement allows the first lens barrel 10, the light shielding element 50, and the second lens barrel 30 to be positioned relatively firmly, and then the first lens barrel 10 and the second lens barrel 30 are fixed, thereby facilitating adjustment of the position of the light shielding element 50 to an appropriate position.
[0043] like Figure 2As shown, the distance d of the second interval along the optical axis 60 direction is greater than or equal to 0.02 mm and less than or equal to 0.2 mm. If the distance d is less than 0.02 mm, the second interval is smaller, the glue accommodated is less, which is unfavorable for the connection between the first lens barrel 10 and the second lens barrel 30. If the distance d is greater than 0.2 mm, the distance between the first lens barrel 10 and the second lens barrel 30 is too large. Although it is convenient to adjust the light-shielding element 50, it increases the distance between the lenses and is simultaneously unfavorable for the control of stray light. When the distance d is set within the range of 0.02 mm to 0.2 mm, it is convenient to control stray light when connecting the first lens barrel 10 and the second lens barrel 30, reduce the generation of stray light, and ensure the imaging quality of the optical imaging lens.
[0044] like Figure 2 As shown, an air gap is provided between the shading element 50 and the first inner supporting surface 23 or the second inner supporting surface 43. The provision of the air gap facilitates adjustment of the position of the shading element 50 and facilitates securing the shading element 50 between the first inner supporting surface 23 and the second inner supporting surface 43. The air gap is used to accommodate glue to secure the shading element 50.
[0045] like Figure 2 As shown, the distance w of the air gap along the optical axis 60 is greater than or equal to 0.001 mm and less than or equal to 0.05 mm. If the distance w is less than 0.001 mm, the air gap is small, which can hold less glue and hinder the securement of the shading element 50. If the distance w is greater than 0.05 mm, the air gap is large, making it easier for light to strike the shading element 50 or the first inner supporting surface 23 or the second inner supporting surface 43, thus generating stray light. Limiting the distance w to between 0.001 mm and 0.05 mm facilitates securement of the shading element 50 while also reducing stray light.
[0046] like Figure 3 As shown, the first axial connecting surface 22 is a conical surface, and the angle θ1 between the first axial connecting surface 22 and the optical axis 60 is greater than or equal to 1° and less than or equal to 45°. The second axial connecting surface 42 is a conical surface, and the angle θ2 between the second axial connecting surface 42 and the optical axis 60 is greater than or equal to 1° and less than or equal to 45°. Setting the first axial connecting surface 22 and the second axial connecting surface 42 as conical surfaces facilitates the fastening of the first lens barrel 10 and the second lens barrel 30, while ensuring the fastening strength of the first lens barrel 10 and the second lens barrel 30. The angle between the first axial connecting surface 22 and the optical axis 60 is limited to a range of 1° to 45°, which is convenient for reducing the generation of stray light and facilitating adjustment of the relative position between the first lens barrel 10 and the second lens barrel 30. The angle between the second axial connecting surface 42 and the optical axis 60 is limited to a range of 1° to 45° in order to adapt to the first axial connecting surface 22.
[0047] As Figure 3 shown, the length H1 of the first inner bearing surface 23 is greater than or equal to 0.06 mm and less than or equal to 1.0 mm. If the length H1 of the first inner bearing surface 23 is less than 0.06 mm, the bearing area between the first inner bearing surface 23 and the light-shielding element 50 is small, which easily leads to the situation that the light-shielding element 50 is not stably borne. If the length H1 of the first inner bearing surface 23 is greater than 1.0 mm, the length of the first inner bearing surface 23 is too long, which easily blocks light and affects the imaging quality of the optical imaging lens. Limiting the length H1 of the first inner bearing surface 23 within the range of 0.06 mm to 1.0 mm can ensure the stable bearing of the light-shielding element 50 while ensuring the imaging quality of the optical imaging lens.
[0048] As Figure 3 shown, the length H2 of the second inner bearing surface 43 is greater than or equal to 0.06 mm and less than or equal to 1.0 mm. If the length H2 of the second inner bearing surface 43 is less than 0.06 mm, the bearing area between the second inner bearing surface 43 and the light-shielding element 50 is small, which easily leads to the situation that the light-shielding element 50 is not stably borne. If the length H2 of the second inner bearing surface 43 is greater than 1.0 mm, the length of the second inner bearing surface 43 is too long, which easily blocks light and affects the imaging quality of the optical imaging lens. Limiting the length H2 of the second inner bearing surface 43 within the range of 0.06 mm to 1.0 mm can ensure the stable bearing of the light-shielding element 50 while ensuring the imaging quality of the optical imaging lens.
[0049] As Figure 3 shown, the thickness t1 of the first connection structure 20 along the optical axis 60 direction of the lens barrel and the thickness t2 of the second connection structure 40 along the optical axis 60 direction satisfy: 0.2 < t1 / t2 < 5.0. Such a setting facilitates adjusting the light-shielding element 5 to an appropriate position on the optical axis 60, and at the same time can ensure the assembly strength of the first connection structure 20 and the second connection structure 40 to ensure the stability of the operation of the first connection structure 20 and the second connection structure 40.
[0050] As Figure 1 shown, the optical imaging lens includes the above-mentioned lens barrel, lenses 80 and light-shielding structures 90. There are multiple lenses 80, and the multiple lenses 80 are arranged at intervals along the axial direction of the lens barrel; there are multiple light-shielding structures 90, and the multiple light-shielding structures 90 are arranged at intervals along the axial direction of the lens barrel, and at least one side surface of the light-shielding structure 90 abuts against the lens 80. The setting of the light-shielding structure 90 can reduce the stray light generated in the optical mechanism area of the lens 80 and improve the imaging quality of the optical imaging lens. The light-shielding element 50 is arranged at an interval from the lens 80.
[0051] The electronic device includes the above-mentioned optical imaging lens. The electronic device with the above-mentioned optical imaging lens has the advantage of high imaging quality.
[0052] Example 2
[0053] The difference from the first embodiment is that the specific structure of the second connection structure 40 is different.
[0054] like Figure 4 and Figure 5 As shown, at least a portion of the first connecting structure 20 is close to the optical axis 60 relative to the inner wall of the lens barrel body of the first lens barrel 10, at least a portion of the second connecting structure 40 is close to the optical axis 60 relative to the inner wall of the lens barrel body of the second lens barrel 30, and the surface of the second connecting structure 40 away from the first connecting structure 20 has a supporting structure 70, and the supporting structure 70 is supported by the lens 80. The provision of the supporting structure 70 facilitates the support and fixation of the second connecting structure 40 and the lens 80, and at the same time facilitates the adjustment of the position between the lens 80 and the light shielding element 50.
[0055] like Figure 5 As shown, the supporting structure 70 of the lens barrel includes a first overlapping surface 71, a supporting surface 72, and a second overlapping surface 73 connected in sequence along the direction close to the optical axis 60. The first overlapping surface 71 and the second overlapping surface 73 are perpendicular to the optical axis 60. The second overlapping surface 73 is closer to the first lens barrel 10 of the lens barrel relative to the first overlapping surface 71. The lens 80 supported by the supporting structure 70 has a first abutting surface 81 abutting against the first overlapping surface 71, an inclined surface 82 corresponding to the supporting surface 72, the inclined surface 82 and the supporting surface 72 are spaced apart, and a second abutting surface 83 corresponding to the second overlapping surface 73 is spaced apart. The first overlapping surface 71 abuts against the first abutting surface 81, which facilitates fixing the position of the lens 80, and the inclined surface 82 is spaced apart from the supporting surface 72, which facilitates adjustment of the position of the lens 80 and the supporting structure 70. The second overlapping surface 73 and the second abutting surface 83 are spaced apart, and the shading structure 90 is disposed between the second overlapping surface 73 and the second abutting surface 83 so that the shading structure 90 shields the optical structural area of the lens 80 to reduce the generation of stray light.
[0056] like Figure 5 As shown, at least one light shielding structure 90 is disposed between the second overlapping surface 73 and the second abutting surface 83, and the light shielding structure 90 abuts against the second overlapping surface 73 and the second abutting surface 83. This arrangement can reduce the generation of stray light and ensure the imaging quality of the optical imaging lens.
[0057] It should be noted that the light shielding structure 90 can be a spacer or a spacer, and the light shielding structure 90 located between the second overlapping surface 73 and the second abutting surface 83 must be a spacer.
[0058] Example 3
[0059] The difference from the first embodiment is that the specific structure of the shading element 50 is different.
[0060] exist Figure 6 In the illustrated embodiment, the shading element 50 includes a base layer 51, and a first surface layer 52 and a second surface layer 53 located on either side of the base layer 51. The base layer 51 may be made of plastic, while the first and second surface layers 52, 53 are black carbonaceous material layers. The black color of the first and second surface layers 52, 53 facilitates the absorption of light by the shading element 50, thereby reducing the generation of stray light.
