Description

Technical Field

[0001] The present application relates to the field of camera technology, and in particular to a lens, a lens assembly, a camera module and a terminal device. Background Art

[0002] In recent years, plastic lenses have been widely used in lenses for automotive, security, virtual reality, and other products due to their strong impact resistance, wear resistance, and processability. As the pixel requirements for lenses become increasingly higher, higher requirements are also placed on the tolerances and assembly tolerances of the various accessories in the lens. In related technologies, the assembly of plastic lenses and metal lens barrels is usually a clearance fit at room temperature. In a high-temperature environment, the lens and the lens barrel will expand, and the expansion coefficient of the lens is greater than that of the lens barrel, resulting in an interference fit between the lens and the lens barrel. At this time, since the lens is softer than the lens barrel, it is easily squeezed and deformed, affecting the optical performance of the lens, and may even lead to the risk of cracking the lens, thereby reducing the yield of the finished product. Utility Model Content

[0003] The embodiments of the present application disclose a lens, a lens assembly, a camera module and a terminal device. The lens can provide expansion space for the lens, reduce the extrusion force between the lens and the lens barrel, and reduce the gap between the lens and the lens barrel, which is beneficial to reducing the extrusion deformation of the lens and improving the connection stability between the lens and the lens barrel, thereby helping to improve the assembly yield of the product.

[0004] To achieve the above objectives, in a first aspect, embodiments of the present application disclose a lens, comprising:

[0005] Main body;

[0006] an outer peripheral portion connected to the outer periphery of the main body portion, the outer peripheral portion having an outer peripheral surface and a first surface along the thickness direction of the main body portion;

[0007] A plurality of raised structures are provided on the outer peripheral surface and are spaced apart around the center of the main body portion, the raised structures including an abutting surface, a connecting surface and a guiding surface, the abutting surface being configured to abut against the inner wall surface of the lens barrel when the lens is assembled on the lens barrel, the connecting surface being connected to the abutting surface and the outer peripheral surface of the peripheral portion, the guiding surface being connected to the abutting surface, and the guiding surface being connected to the first surface and the outer peripheral surface, the guiding surface being configured to guide the installation position of the lens on the lens barrel when the lens is assembled on the lens barrel.

[0008] The lens provided in the embodiment of the present application achieves assembly and cooperation between the lens and the lens barrel by abutting the abutting surface of the raised structure on the outer peripheral portion with the inner wall surface of the lens barrel. On the one hand, it can reduce the connection area between the lens and the lens barrel; on the other hand, it can create a gap between the outer peripheral portion and the lens barrel. In this way, even in a high-temperature environment, when the lens and the lens barrel expand due to heat, the gap between the outer peripheral portion and the lens barrel can provide expansion space for the lens, thereby reducing the squeezing force between the lens and the lens barrel, and further reducing the squeezing deformation of the lens, which is beneficial to reducing the risk of cracking of the lens after the high-temperature process, and is beneficial to reducing the surface variation of the lens in the high-temperature environment, thereby making the quality of the lens more stable. In addition, the raised structure can make the gap between the outer diameter of the lens and the inner diameter of the lens barrel smaller, which is beneficial to improving the stability of the connection between the lens and the lens barrel, thereby improving the assembly yield of the product.

[0009] In addition, the guide surface of the raised structure can be used to correct the variance of the lens when it is assembled with the lens barrel. Specifically, after the lens is assembled in the lens barrel, the installation position and angle of the lens in the lens barrel are adjusted through the guide surface so that each raised structure abuts against the inner wall surface of the lens barrel and is in the correct position, thereby improving the optical performance of the product and helping to improve the assembly yield of the product.

[0010] As an optional embodiment, the angle between the center of two adjacent protrusion structures and the center of the main body is 30° to 60°;

[0011] and / or,

[0012] The number of the protrusion structures is 6 to 10.

[0013] The above-mentioned arrangement of the number of raised structures and the angles between the raised structures can improve the stability of the connection between the lens and the lens barrel. Compared with the arrangement in which the number of raised structures is less than , the above-mentioned embodiment can avoid the situation in which too many lenses are missing, resulting in too few contact points with the lens barrel, thereby avoiding the situation in which the eccentric force of the lens is too large, which is conducive to improving the stability of the connection between the lens and the lens barrel. At the same time, compared with the arrangement in which the number of raised structures is greater than , the above-mentioned embodiment can avoid the situation in which the space between the raised structures is significantly reduced due to the excessive number, and reduce the difficulty of processing and demolding, which is conducive to facilitating the processing and arrangement of the raised structures and providing operating space for the lens when assembling it to the lens barrel, and is conducive to reducing the effect of surface variation.

[0014] As an optional embodiment, the abutting surface is a curved surface, and the curvature radius of the curved surface of the convex structure is less than or equal to the curvature radius of the inner wall surface of the lens barrel. By setting the curvature radius of the curved surface of the convex structure equal to the curvature radius of the inner wall surface of the lens barrel, the abutting surface can be aligned with the inner wall surface of the lens barrel, thereby facilitating improved stability of the connection between the lens and the lens barrel. By setting the curvature radius of the curved surface of the convex structure smaller than the curvature radius of the inner wall surface of the lens barrel, the contact area between the abutting surface and the inner wall surface of the lens barrel can be reduced, thereby enabling more space between the outer peripheral portion and the inner wall surface of the lens barrel for the lens and the lens barrel to expand, thereby facilitating the avoidance of the risk of extrusion deformation between the lens and the lens barrel, and further facilitating improved assembly yield between the lens and the lens barrel.

[0015] As an optional embodiment, the abutting surface is a curved surface, the projection of the curved surface on the first surface is an arc, and the arc length of the arc is 0.3mm to 0.8mm. By setting the arc length range of the abutting surface of the curved surface, on the one hand, it is facilitated to process and form the raised structure, avoiding the occurrence of defects or even failure of the raised structure during processing due to an excessively short arc length; on the other hand, it is beneficial to protect the overall surface effect of the lens, avoiding the reduction of the space between the outer peripheral portion and the inner wall surface of the lens barrel due to an excessively long arc length, thereby reducing the effect of the raised structure.

[0016] As an optional embodiment, the height of the protruding structure protruding from the outer peripheral surface is 0.03mm to 0.2mm;

[0017] and / or,

[0018] The thickness of the protruding structure along the thickness direction of the main body portion is 0.4 mm to 1 mm.

[0019] In the above embodiment, by setting the height range of the protruding outer peripheral surface of the protruding structure, it is possible to ensure that the protruding structure abuts against the inner wall surface of the lens barrel, thereby facilitating the stable connection between the lens and the lens barrel. At the same time, it is also possible to facilitate the transmission of force between the lens and the lens barrel to the entire lens, thereby avoiding the situation where the lens is locally subjected to force and thus damaged when the height of the protruding outer peripheral surface of the protruding structure is too small. Furthermore, it is possible to avoid the situation where the processing and demolding of the lens are increased due to the height of the protruding outer peripheral surface of the protruding structure being too large.

[0020] In addition, in the above embodiment, by setting the thickness range of the protruding structure in the thickness direction of the main body, it is beneficial to improve the connection stability between the lens and the lens barrel and facilitate the assembly of the lens. It can avoid the situation where the protruding structure is too thin in the thickness direction of the main body, resulting in less contact between the protruding structure and the inner wall surface of the lens barrel, thereby causing an unstable connection between the lens and the inner wall surface of the lens barrel. It can also avoid the situation where the force strength between the lens and the inner wall surface of the lens barrel is too large when the thickness of the protruding structure in the thickness direction of the main body is too large, resulting in damage to the lens. At the same time, by setting the thickness range of the protruding structure in the thickness direction of the main body, it can also avoid the situation where the lens is stuck when the lens is assembled in the lens barrel due to the protruding structure being too thick in the thickness direction of the main body, especially when the lens is assembled with interference fit.

[0021] As an optional embodiment, the guide surface is configured as a sloped surface that gradually slopes from the first surface toward the abutment surface. This sloped guide surface can provide assembly guide for the lens during assembly with the lens barrel, thereby guiding the lens to a predetermined installation position and adjusting the lens's installation position. This helps improve the optical performance of the lens assembly and thus the assembly yield of the product. Furthermore, the sloped guide surface reduces the difficulty of demolding the mirror surface, facilitating lens processing.

[0022] As an optional embodiment, the guide surfaces are disposed around the center of the main body and are sequentially connected. The guide surfaces are connected around the periphery, that is, the guide surfaces are continuous on the periphery. This facilitates adjustment of the lens installation position in various directions, thereby improving the optical performance of the lens assembly and thereby increasing the assembly yield of the product.

[0023] As an optional embodiment, the protruding structure is integrally formed on the peripheral portion. This facilitates lens processing and reduces overall lens processing difficulty. At the same time, the integral molding facilitates lens installation and reduces the assembly process of the lens assembly.

[0024] In a second aspect, embodiments of the present application further disclose a lens assembly, comprising a lens barrel and the lens described in the first aspect above, wherein the lens barrel has an inner wall surface, and the protruding structure of the lens abuts against the inner wall surface. The lens assembly having the lens described in the first aspect above can also provide expansion space for the lens, reduce the squeezing force between the lens and the lens barrel, and reduce the gap between the lens and the lens barrel, which is conducive to reducing squeezing deformation of the lens and improving the stability of the connection between the lens and the lens barrel, thereby facilitating an improvement in the assembly yield of the product.

[0025] In a third aspect, embodiments of the present application further disclose a camera module comprising the lens assembly and an image sensor as described in the second aspect, wherein the lens assembly is electrically connected to the image sensor. The lens assembly described in the second aspect and the lens described in the first aspect can also provide expansion space for the lens, reduce the squeezing force between the lens and the lens barrel, and reduce the gap between the lens and the lens barrel, thereby reducing squeezing deformation of the lens and improving the stability of the connection between the lens and the lens barrel, thereby improving the assembly yield of the product.

[0026] In a fourth aspect, an embodiment of the present application further discloses a terminal device, comprising the camera module as described in the third aspect above.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] The lens, lens assembly, camera module, and terminal device provided by the embodiments of the present application are characterized in that the lens is assembled with the lens barrel by abutting the inner wall surface of the lens barrel with a raised surface on the outer peripheral portion. The lens is connected to the lens barrel by the raised surface, which, on the one hand, reduces the connection area between the lens and the lens barrel; on the other hand, creates a gap between the outer peripheral portion and the lens barrel. Thus, even in a high-temperature environment, when the lens and the lens barrel expand due to heat, the gap between the outer peripheral portion and the lens barrel can provide expansion space for the lens, reducing the squeezing force between the lens and the lens barrel, thereby reducing the squeezing deformation of the lens and further reducing the risk of cracking of the lens after a high-temperature process, thereby reducing the surface variation of the lens in a high-temperature environment, thereby making the quality of the lens more stable. Furthermore, the raised structure allows the gap between the outer diameter of the lens and the inner diameter of the lens barrel to be set smaller, which is conducive to improving the stability of the connection between the lens and the lens barrel, thereby facilitating the improvement of the assembly yield of the product.

[0029] In addition, the guide surface of the raised structure can be used to correct the variance of the lens when it is assembled with the lens barrel. Specifically, after the lens is assembled in the lens barrel, the installation position and angle of the lens in the lens barrel are adjusted through the guide surface so that each raised structure abuts against the inner wall surface of the lens barrel and is in the correct position, thereby improving the optical performance of the product and helping to improve the assembly yield of the product.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] In this application, terms such as "upper," "lower," "inner," and "outer" indicate positions or locations based on those shown in the accompanying drawings. These terms are intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to specific positions, or to their construction or operation in a specific position.

[0042] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0043] Furthermore, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0044] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0045] Plastic lenses are showing a continuous growth trend in the lens market due to their strong impact resistance, wear resistance and strong machinability. They have broad development prospects and have been widely used in lens assemblies for automotive, security, virtual reality and other products. With the development of camera technology, the pixel requirements for lens assemblies are getting higher and higher, and higher requirements are also placed on the tolerances and assembly tolerances of various accessories in the lens assembly. In related technologies, the assembly of plastic lenses and metal lens barrels is usually a clearance fit at room temperature. However, in a high temperature environment, the lens and the lens barrel will expand, and the expansion coefficient of the lens is greater than that of the lens barrel, which can easily lead to an interference fit between the lens and the lens barrel. At this time, since the lens is softer than the lens barrel, the lens is easily squeezed and deformed, which affects the optical performance of the lens assembly and may even lead to the risk of cracking the lens, thereby reducing the yield of the finished product.

[0046] To address this issue, the inventors attempted to increase the gap between the lens and the lens barrel to prevent the lens from being squeezed and deformed due to the interference fit caused by expansion in a high-temperature environment. However, while increasing the gap between the lens and the lens barrel prevents squeezing and deformation, it also reduces the stability of the connection between the lens and the lens barrel at room temperature. Furthermore, the increased space between the lens and the lens barrel makes it difficult to position the lens during assembly, making it prone to skew and difficult to guide, thus affecting the assembly yield of the product.

[0047] In view of this, the embodiments of the present application provide a lens, a lens assembly, a camera module and a terminal device. The lens is provided with multiple protrusion structures on the outer peripheral part of the lens. The abutment surface of the protrusion structure abuts against the inner wall surface of the lens barrel when the lens is assembled in the lens barrel, which can provide expansion space for the lens, thereby reducing the extrusion force between the lens and the lens barrel, and can reduce the gap between the lens and the lens barrel, which is beneficial to reducing the extrusion deformation of the lens, and is beneficial to improving the connection stability between the lens and the lens barrel, thereby helping to improve the assembly yield of the product.

[0048] On this basis, the present application also provides a guide surface on the raised mechanism, which can perform variance assembly correction on the lens when the lens is assembled with the lens barrel, so as to locate and correct the installation position of the lens, so that each raised structure abuts against the inner wall surface of the lens barrel and is in the correct position, thereby improving the optical performance of the product and helping to improve the assembly yield of the product.

[0049] The technical solution of the present application will be further described below with reference to specific embodiments and drawings.

[0050] See also Figures 1 to 4 , Figure 1 This is a schematic structural diagram of a lens provided by an embodiment of the present application at one viewing angle; Figure 2 is a schematic structural diagram of the lens provided in an embodiment of the present application from another viewing angle; Figure 3 is a side view of a lens provided in an embodiment of the present application; Figure 4 : is a bottom view of a lens provided by an embodiment of the present application. In a first aspect, an embodiment of the present application discloses a lens 100, which includes a main body 1, a peripheral portion 2, and a plurality of raised structures 3. The peripheral portion 2 is connected to the periphery of the main body 1, and the peripheral portion 2 has an outer peripheral surface 23 and a first surface 21 along the thickness direction of the main body 1. The plurality of raised structures 3 are arranged on the outer peripheral surface 23 and are spaced around the center of the main body 1. The raised structures 3 include abutting surfaces 31, connecting surfaces 32, and guide surfaces 33. The abutting surface 31 is configured to abut against the inner wall surface of the lens barrel when the lens 100 is assembled in the lens barrel. The connecting surface 32 is connected to the abutting surface 31 and the outer peripheral surface 23 of the peripheral portion 2. The guide surface 33 is connected to the abutting surface 31, and the guide surface 33 is connected to the first surface 21 and the outer peripheral surface 23. The guide surface 33 is configured to guide the installation position of the lens 100 on the lens barrel when the lens 100 is assembled in the lens barrel.

[0051] The lens 100 provided in the embodiment of the present application achieves assembly and fit between the lens 100 and the lens barrel by abutting the abutting surface 31 of the raised structure 3 on the outer peripheral portion 2 against the inner wall surface of the lens barrel. This, on the one hand, can reduce the connection area between the lens 100 and the lens barrel; on the other hand, it can create a gap between the outer peripheral portion 2 and the lens barrel. Thus, even in a high-temperature environment, when the lens 100 and the lens barrel expand due to heat, the gap between the outer peripheral portion 2 and the lens barrel provides space for the lens 100 to expand, thereby reducing the compressive force between the lens 100 and the lens barrel, and further reducing the compressive deformation of the lens 100. This helps reduce the risk of cracking of the lens 100 after high-temperature processing and helps reduce the surface variation of the lens 100 in high-temperature environments, thereby ensuring more stable quality of the lens 100. Furthermore, the raised structure 3 allows the gap between the outer diameter of the lens 100 and the inner diameter of the lens barrel to be set smaller, which helps improve the stability of the connection between the lens 100 and the lens barrel, thereby improving the assembly yield rate of the product.

[0052] In addition, through the guide surface 33 of the raised structure 3, the lens 100 can be assembled and corrected for variance when the lens 100 is assembled with the lens barrel. Specifically, after the lens 100 is assembled in the lens barrel, the installation position and angle of the lens 100 in the lens barrel are adjusted through the guide surface 33 so that each raised structure 3 abuts against the inner wall surface of the lens barrel and is in the correct position, thereby improving the optical performance of the product and helping to improve the assembly yield of the product.

[0053] It is understandable that if Figures 1 to 4 As shown, the peripheral portion 2 has a second surface 22 facing away from the first surface 21 , and a plurality of protrusion structures 3 are disposed on a side of the outer peripheral surface 23 of the peripheral portion 2 close to the second surface 22 .

[0054] Optionally, the main body portion 1 includes a convex lens, a concave lens, a spherical lens, a toric lens, etc., which is not limited in this embodiment.

[0055] Optionally, the main body 1 is configured to process the optical path, that is, the light emitted by the photographed object propagates along a preset optical path after passing through the main body 1. The "preset optical path" here is determined by the performance of the main body 1 itself. For example, when the main body 1 is a convex lens, the light emitted by the photographed object has a converging effect after passing through the convex lens, that is, the light propagates in a direction close to the optical axis after passing through the convex lens. For another example, when the main body 1 is a concave lens, the light emitted by the photographed object has a diverging effect after passing through the concave lens, that is, the light propagates in a direction away from the optical axis after passing through the concave lens.

[0056] Optionally, the peripheral portion 2 is configured to serve as a supporting portion when the lens 100 is assembled in the lens barrel. In other words, the peripheral portion 2 serves as a connecting portion between the main portion 1 and the lens barrel to prevent colloids or other substances from sticking to the main portion 1 and affecting optical imaging.

[0057] Optionally, the material of the main body 1 includes polycarbonate, polystyrene, polyester, etc., which is not limited in this embodiment.

[0058] Optionally, the material of the peripheral portion 2 includes polycarbonate, polystyrene, polyester, etc., which is not limited in this embodiment.

[0059] Optionally, the material of the peripheral portion 2 may be the same as or different from that of the main portion 1, and this embodiment does not limit this. When the material of the peripheral portion 2 is the same as that of the main portion 1, illustratively, the material of the main portion 1 is polycarbonate, and the material of the peripheral portion 2 is also polycarbonate. When the material of the peripheral portion 2 is different from that of the main portion 1, illustratively, the material of the main portion 1 is polycarbonate, and the material of the peripheral portion 2 is polystyrene; or, the material of the main portion 1 is polycarbonate, and the material of the peripheral portion 2 is polyester; or, the material of the main portion 1 is polystyrene, and the material of the peripheral portion 2 is polycarbonate; or, the material of the main portion 1 is polystyrene, and the material of the peripheral portion 2 is polycarbonate; or, the material of the main portion 1 is polystyrene, and the material of the peripheral portion 2 is polyester; or, the material of the main portion 1 is polyester, and the material of the peripheral portion 2 is polycarbonate; or, the material of the main portion 1 is polyester, and the material of the peripheral portion 2 is polycarbonate; or, the material of the main portion 1 is polyester, and the material of the peripheral portion 2 is polystyrene.

[0060] Optionally, the main body portion 1 and the peripheral portion 2 may be integrally formed, or alternatively, may be separately formed, which is not limited in this embodiment. Exemplarily, to reduce the overall processing difficulty of the lens 100, the main body portion 1 and the peripheral portion 2 are integrally formed. It is understood that the main body portion 1 and the peripheral portion 2 may be integrally formed using 3D printing or injection molding, which is not limited in this embodiment.

[0061] Optionally, the material of the protruding structure 3 may include polycarbonate, polystyrene, polyester, resin, etc., which is not limited in this embodiment. It is understandable that the material of the protruding structure 3 may be the same as or different from the material of the peripheral portion 2, which is not detailed in this embodiment.

[0062] Optionally, the raised structure 3 and the peripheral portion 2 may be integrally formed or separately formed, which is not limited in this embodiment. For example, the raised structure 3 is integrally formed with the peripheral portion 2. This facilitates the processing of the lens 100 and reduces the overall processing difficulty of the lens 100. Furthermore, the integral molding facilitates the installation of the lens 100 and reduces the assembly steps of the lens assembly 200.

[0063] Optionally, the abutting surface 31 may be a spherical surface, an arcuate surface (the abutting surface 31 being an arcuate surface will be described in detail below), etc., which is not limited in this embodiment.

[0064] In order to improve the stability of the connection between the lens 100 and the lens barrel, the number and distribution of the protruding structures 3 can be set. For example, the angle α between the center of two adjacent protruding structures 3 and the center of the main part 1 is 30° to 60°.

[0065] For another example, the number of the protruding structures 3 is 6 to 10.

[0066] For another example, the angle α between the centers of two adjacent protruding structures 3 and the center line of the main body 1 is 30° to 60°, and the number of the protruding structures 3 is 6 to 10.

[0067] The above-mentioned arrangement of the number of protruding structures 3 and the angle α between the protruding structures 3 can improve the connection stability between the lens 100 and the lens barrel. Compared with an arrangement in which the number of protruding structures 3 is less than 6, the above-mentioned embodiment can avoid the situation in which too many missing lenses 100 result in too few contact points with the lens barrel, thereby avoiding the situation in which the eccentric force of the lens 100 is too large, which is conducive to improving the stability of the connection between the lens 100 and the lens barrel. At the same time, compared with an arrangement in which the number of protruding structures 3 is greater than 10, the above-mentioned embodiment can avoid the situation in which the space between the protruding structures 3 is significantly reduced due to an excessive number of protruding structures 3, and reduce the difficulty of processing and demolding, which is conducive to facilitating the processing and arrangement of the protruding structures 3 and providing operating space when assembling the lens 100 to the lens barrel, and is conducive to reducing the effect of surface variation.

[0068] Optionally, the angle α between the center of the two adjacent protrusion structures 3 and the center of the main body 1 is 30° to 60°, which can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc., which is not limited in this embodiment. Figure 4 As shown, the angle α between the center of two adjacent protruding structures 3 and the center of the main part 1 is 60°.

[0069] It is understood that the angle α between the centers of the two adjacent protruding structures 3 and the center of the main portion 1 is 30° to 60°. Alternatively, the angle α between the centers of the two adjacent protruding structures 3 and the center of the main portion 1 is 30° to 60°. Alternatively, the angle α between the centers of the two adjacent protruding structures 3 and the center of the main portion 1 is 35° to 60°. Alternatively, the angle α between the centers of the two adjacent protruding structures 3 and the center of the main portion 1 is 40° to 60°. Alternatively, the angle α between the centers of the two adjacent protruding structures 3 and the center of the main portion 1 is 40° to 60°. Alternatively, the angle α between the centers of the two adjacent protruding structures 3 and the center of the main portion 1 is 40° to 55°. Alternatively, the angle α between the centers of the two adjacent protruding structures 3 and the center of the main portion 1 is 40° to 50°. Alternatively, the angle α between the centers of the two adjacent protruding structures 3 and the center of the main portion 1 is 40° to 45°, and so on. This embodiment is not limited to this.

[0070] Optionally, the number of the protrusion structures 3 is 6 to 10, which may be 6, 7, 8, 9, 10, etc., and this embodiment does not limit this. Figure 4 As shown, the number of the protruding structures 3 is six.

[0071] Optionally, the number of the protrusion structures 3 is 6 to 10, or the number of the protrusion structures 3 is 6 to 10, or the number of the protrusion structures 3 is 6 to 9, or the number of the protrusion structures 3 is 6 to 8, etc., which is not limited in this embodiment.

[0072] As an optional implementation, Figures 1 to 4 As shown, the contact surface 31 is a curved surface, and the curvature radius of the curved surface of the convex structure 3 is equal to the curvature radius of the inner wall surface of the lens barrel. With this embodiment, the contact surface 31 can fit with the inner wall surface of the lens barrel, thereby facilitating the connection stability between the lens 100 and the lens barrel.

[0073] As another optional embodiment, the contact surface 31 is a curved surface, and the curvature radius of the curved surface of the protruding structure 3 is smaller than the curvature radius of the inner wall surface of the lens barrel. Using this embodiment, the contact area between the contact surface 31 and the inner wall surface of the lens barrel can be reduced, thereby allowing more space between the outer peripheral portion 2 and the inner wall surface of the lens barrel to allow the lens 100 and the lens barrel to expand, thereby helping to avoid the risk of compression deformation between the lens 100 and the lens barrel, and further helping to improve the assembly yield between the lens 100 and the lens barrel.

[0074] It is understandable that the size of the protruding structure 3 can be set to achieve a more stable connection between the peripheral portion 2 and the inner wall surface of the lens barrel and a more reasonable force distribution, thereby improving the assembly yield of the product, as described below:

[0075] As an optional implementation, Figure 3 As shown, the thickness C of the raised structure 3 along the thickness direction of the main body 1 is 0.4 mm to 1 mm. By setting the range of the thickness C of the raised structure 3 along the thickness direction of the main body 1, it is beneficial to improve the connection stability of the lens 100 and the lens barrel and facilitate the assembly of the lens 100. It can not only avoid the situation where the raised structure 3 in the thickness direction of the main body 1 is too small, resulting in less contact between the raised structure 3 and the inner wall surface of the lens barrel, thereby causing the lens 100 to be unstable with the inner wall surface of the lens barrel, but also avoid the situation where the thickness C of the raised structure 3 in the thickness direction of the main body 1 is too large, resulting in excessive force between the lens 100 and the inner wall surface of the lens barrel, which may cause damage to the lens 100. In addition, by setting the range of the thickness C of the raised structure 3 in the thickness direction of the main body 1, it can also avoid the situation where the lens 100 is stuck when assembled in the lens barrel due to the raised structure 3 in the thickness direction of the main body 1 being too large, especially when the lens 100 is assembled with an interference fit.

[0076] Optionally, the thickness C of the protruding structure 3 along the thickness direction of the main body 1 is 0.4 mm to 1 mm, and can be 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, etc., which is not limited in this embodiment.

[0077] Optionally, the thickness C of the raised structure 3 along the thickness direction of the main portion 1 is 0.4 mm to 1 mm, or the thickness C of the raised structure 3 along the thickness direction of the main portion 1 is 0.4 mm to 1 mm. Alternatively, the thickness C of the raised structure 3 along the thickness direction of the main portion 1 is 0.5 mm to 1 mm. Alternatively, the thickness C of the raised structure 3 along the thickness direction of the main portion 1 is 0.6 mm to 1 mm. Alternatively, the thickness C of the raised structure 3 along the thickness direction of the main portion 1 is 0.6 mm to 0.9 mm. Alternatively, the thickness C of the raised structure 3 along the thickness direction of the main portion 1 is 0.6 mm to 0.8 mm. Alternatively, the thickness C of the raised structure 3 along the thickness direction of the main portion 1 is 0.6 mm to 0.7 mm.

[0078] As an optional implementation, Figure 4The height B of the raised structure 3 above the outer peripheral surface 23 is shown to be between 0.03 mm and 0.2 mm. By setting the range of the height B of the raised structure 3 above the outer peripheral surface 23, the raised structure 3 can be ensured to abut against the inner wall of the lens barrel, thereby improving the stability of the connection between the lens 100 and the lens barrel. This also facilitates the transmission of force between the lens 100 and the lens barrel to the entire lens 100, preventing the lens 100 from being locally stressed and damaged when the height B of the raised structure 3 above the outer peripheral surface 23 is too small. Furthermore, it can prevent the lens 100 from being difficult to process and demold due to an excessively large height B of the raised structure 3 above the outer peripheral surface 23.

[0079] Optionally, the height B of the protruding structure 3 protruding from the outer peripheral surface 23 is 0.03mm to 0.2mm, which can be 0.03mm, 0.04mm, 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, 0.1mm, 0.12mm, 0.14mm, 0.16mm, 0.18mm, 0.2mm, etc., which is not limited in this embodiment.

[0080] Optionally, the height B of the protruding structure 3 protruding from the outer peripheral surface 23 is 0.03mm to 0.2mm, or the height B of the protruding structure 3 protruding from the outer peripheral surface 23 is 0.03mm to 0.2mm. Alternatively, the height B of the protruding structure 3 protruding from the outer peripheral surface 23 is 0.05mm to 0.2mm. Alternatively, the height B of the protruding structure 3 protruding from the outer peripheral surface 23 is 0.08mm to 0.2mm. Alternatively, the height B of the protruding structure 3 protruding from the outer peripheral surface 23 is 0.1mm to 0.2mm. Alternatively, the height B of the protruding structure 3 protruding from the outer peripheral surface 23 is 0.1mm to 0.18mm. Alternatively, the height B of the protruding structure 3 protruding from the outer peripheral surface 23 is 0.1mm to 0.16mm. Alternatively, the height B of the protruding structure 3 protruding from the outer peripheral surface 23 is 0.1mm to 0.14mm, and so on. This embodiment is not limited to this.

[0081] As an optional implementation, Figure 4 As shown, the contact surface 31 is a curved surface, the projection of which on the first surface 21 is an arc, and the arc length A of the arc ranges from 0.3 mm to 0.8 mm. Setting the arc length A range for the curved contact surface 31 facilitates the processing and forming of the protruding structure 3, preventing defects or even failure of the protruding structure 3 during processing due to an excessively short arc length A. Furthermore, it helps preserve the overall surface shape of the lens 100, preventing a reduction in the space between the outer peripheral portion 2 and the inner wall of the lens barrel due to an excessively long arc length A, thereby reducing the effectiveness of the protruding structure 3.

[0082] Optionally, the arc length A of the arc is 0.3 mm to 0.8 mm, and can be 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, etc., which is not limited in this embodiment.

[0083] Optionally, the arc length A of the arc is 0.3 mm to 0.8 mm, or the arc length A of the arc is 0.3 mm to 0.8 mm. Alternatively, the arc length A of the arc is 0.4 mm to 0.8 mm. Alternatively, the arc length A of the arc is 0.5 mm to 0.8 mm. Alternatively, the arc length A of the arc is 0.5 mm to 0.7 mm. Alternatively, the arc length A of the arc is 0.5 mm to 0.6 mm, and so on. This embodiment does not limit this.

[0084] In order to improve the optical performance of the lens assembly, a guide surface 33 can be provided to guide the installation position of the lens 100 on the lens barrel when the lens 100 is assembled to the lens barrel. Specifically, the guide surface 33 is constructed as an inclined surface that gradually tilts from the first surface 21 toward the abutment surface 31. The sloped guide surface 33 can provide a variance assembly guide for the lens 100 when the lens 100 is assembled with the lens barrel, thereby guiding the lens 100 to be assembled to a predetermined installation position and adjusting the installation position of the lens 100, which is beneficial to improving the optical performance of the lens assembly and thus helping to increase the assembly yield of the product. In addition, the sloped guide surface 33 helps to reduce the difficulty of mirror processing and demolding, facilitating the processing of the lens 100.

[0085] As an optional embodiment, the guide surfaces 33 are disposed around the center of the main body 1 and are sequentially connected. Since the guide surfaces 33 are connected around the peripheral portion 2, that is, the guide surfaces are continuous on the peripheral portion, this facilitates adjustment of the installation position of the lens 100 in various directions, thereby improving the optical performance of the lens assembly and thereby increasing the assembly yield of the product.

[0086] Alternatively, as Figures 1 to 4 As shown, when the main portion 1, the peripheral portion 2, and the raised structures 3 are molded together by injection molding, in order not to affect the optical performance of the lens 100, the feed port for the injection molding material is usually set on the outer peripheral surface 23 of the peripheral portion 2. After the lens 100 is molded, the excess material at the feed port needs to be sheared off, thus forming a notch 4 on the lens 100. Specifically, the lens 100 also includes a notch 4, which is set on the outer peripheral surface 23 and is located between the two raised structures 3. It is understandable that the design angles of the two raised structures 3 near the notch 4 are "different" from those of the other raised structures 3, but this "difference" does not affect the effect of the raised structures 3.
