[0107] This disclosure provides an imaging lens having an optical axis and comprising multiple lens elements, an annular light-blocking structure, a plastic lens barrel, an object-side fixing member, and an image-side fixing member.

[0108] Lens elements are sequentially arranged along the optical axis, including an object-side lens element and an image-side lens element. The object-side lens element, the annular light-blocking structure, and the image-side lens element are sequentially arranged along the optical axis from the object side to the image side of the imaging lens. The annular light-blocking structure includes a light-blocking surface, an object-side surface, an image-side surface, and multiple strip-shaped wedge structures. The light-blocking surface is arranged around and facing the optical axis. The object-side surface faces the object side of the imaging lens and extends from the light-blocking surface in a direction away from the optical axis. The image-side surface faces the image side of the imaging lens and extends from the light-blocking surface in a direction away from the optical axis. The strip-shaped wedge structures are disposed on the light-blocking surface, each extending from the object-side surface to the image-side surface and arranged in a direction surrounding the optical axis. Each strip-shaped wedge structure includes a tapered portion that tapers towards the optical axis. Specifically, the object-side lens element is the object-side lens element among the lens elements, and the image-side lens element is the image-side lens element among the lens elements.

[0109] A lens element and an annular light-shielding structure are disposed within a plastic lens barrel, which includes an object-side portion, an image-side portion, an inner peripheral portion, and an outer peripheral portion. The object-side portion faces the object side of the imaging lens and forms an object-side opening, through which the object-side lens element is inserted into the plastic lens barrel. The image-side portion faces the image side of the imaging lens and forms an image-side opening, through which the image-side lens element is inserted into the plastic lens barrel. The inner peripheral portion connects the object-side portion and the image-side portion and faces the optical axis. The outer peripheral portion connects the object-side portion and the image-side portion and is disposed opposite to the inner peripheral portion in a direction away from the optical axis.

[0110] The object-side fixing member is disposed at the object side of the plastic lens barrel, and the object-side fixing member includes an object-side fixing portion and an object-side abutting portion. The object-side fixing portion surrounds the outer peripheral portion of the plastic lens barrel. The object-side abutting portion extends from the object-side fixing portion toward the optical axis and abuts against the object-side lens element to fix the object-side lens element to the object side of the plastic lens barrel. Further, the fixing manner of the object-side fixing portion and the plastic lens barrel and the fixing manner of the image-side fixing portion and the plastic lens barrel can be snap-ring fixing, thread engagement or glue bonding, but are not limited thereto.

[0112] Specifically, the present disclosure provides a two-way assembled imaging lens. Each lens element is assembled by two fixing members, and together with the design of the annular light-shielding structure, it is used to ensure the assembly feasibility of the product and provide relatively high optical quality. The outer-packaged object-side fixing member can protect the structure of the imaging lens and improve the environmental tolerance of the imaging lens to extend the product life. Through the design of the strip-shaped wedge structure, the imaging lens can reduce the interference of stray light and provide better image recognition ability in a strong sunlight environment or a dark night environment. Through the design of the annular light-shielding structure in combination with the object-side fixing member, the annular light-shielding structure is not easily deformed due to environmental temperature changes.

[0113] The minimum diameter of the object-side fixing member is Do, the minimum diameter of the image-side fixing member is Di, and the minimum diameter of the light-shielding surface is Ds, which can satisfy the following conditions: 0.03 < Ds / (Do + Di) < 0.75. By appropriately setting the ratio of the opening of the plastic lens barrel to the opening of the light-shielding surface, better image resolution quality can be obtained and the product reliability can be taken into account. In addition, it can satisfy the following conditions: 0.05 < Ds / (Do + Di) < 0.55. Thereby, the production yield of the annular light-shielding structure can be further improved. In addition, it can satisfy the following conditions: 0.08 < Ds / (Do + Di) < 0.45. Thereby, a better anti-stray light effect can be further provided.

[0114] The distance between the object-side abutting portion of the object-side fixing member and the object side surface of the annular light-shielding structure in the direction parallel to the optical axis is Lr, and the length of the object-side fixing member in the direction parallel to the optical axis is Lo, which can satisfy the following conditions: 0.15 < Lr / Lo < 1. In addition, it can satisfy the following conditions: 0.20 < Lr / Lo < 0.85. Thereby, better assembly stability of the imaging lens can be further provided.

[0115] The object-side lens element can be a glass lens element, and the image-side lens element can be a plastic lens element. Thus, the imaging lens composed of the glass lens and the plastic lens can consider the temperature effect and meet the miniaturization requirements simultaneously.

[0116] The object-side lens element can include a convex surface, where the convex surface faces the object side of the imaging lens. Thus, better light-gathering efficiency can be provided, which is beneficial to improving the image recognition ability of the product.

[0117] The object-side bearing portion of the object-side fixing member can have a first alignment structure, the object-side lens element can have a second alignment structure, and the first alignment structure and the second alignment structure lean on each other to align the object-side lens element to the optical axis of the imaging lens. Thus, it is beneficial to simplify the assembly process.

[0118] The annular light-shielding structure can be provided on the inner peripheral portion of the plastic lens barrel, and the annular light-shielding structure on the inner peripheral portion extends towards the optical axis from the inner peripheral portion. By providing the annular light-shielding structure, stray light can be reduced, thereby improving the optical imaging quality.

[0119] The annular light-shielding structure can be provided on a spacer of the imaging lens, and the spacer is provided between two of the lens elements. By providing the annular light-shielding structure, stray light can be reduced, thereby improving the optical imaging quality.

[0120] The image-side fixing member can include an image-side fixing portion and an image-side bearing portion. The image-side fixing portion surrounds the outer peripheral portion of the plastic lens barrel, and the image-side bearing portion extends from the image-side fixing portion towards the optical axis and bears on the image-side lens element. The overall structure of the imaging lens can be protected by the outer wrapping type image-side fixing member, and the environmental tolerance of the imaging lens can be improved to extend the product life.

[0121] The distance between the object side and the image side in the direction parallel to the optical axis is La, and the minimum diameter of the light-shielding surface is Ds, which can satisfy the following conditions: 0.02 < La / Ds < 1. Thus, suitable molding conditions for the strip wedge-shaped structure can be provided. In addition, it can satisfy the following conditions: 0.03 < La / Ds < 0.8. Thus, better light-shielding efficiency can be provided.

[0122] The minimum diameter of the object-side fixing member is Do, the minimum diameter of the image-side fixing member is Di, and the minimum diameter of the light-shielding surface is Ds, which can satisfy the following conditions: |Do – Di| < Ds. Thus, the production yield of the annular light-shielding structure can be improved.

[0123] The angle between each strip wedge-shaped structure and the optical axis is As, which can satisfy the following conditions: 0° ≤ As < 60°. Thus, the light-shielding efficiency of the annular light-shielding structure can be further improved. In addition, it can satisfy the following conditions: 0° ≤ As < 45°. Thus, the structural integrity of the strip wedge-shaped structure can be improved.
