Detailed Description

The detailed features and advantages of the present invention are described in detail in the embodiments below, which are sufficient for anyone skilled in the art to understand the technical contents of the present invention and to implement the present invention, and the related objects and advantages of the present invention can be easily understood by anyone skilled in the art according to the disclosure of the present specification, the protection scope of the claims and the attached drawings. The following examples further illustrate aspects of the present invention in detail, but are not intended to limit the scope of the invention in any way.

The invention provides an imaging lens which is provided with an optical axis and comprises at least one plastic lens.

The at least one plastic lens comprises an optical effective part and an outer peripheral part from the center to the periphery in sequence. The optical axis passes through the optically effective portion. The outer circumference portion surrounds the optical effective portion and includes at least one annular groove structure, at least one conical surface, at least one flat bearing portion and at least one full annular connecting portion on at least one of the object side and the image side of the optical effective portion.

The at least one annular groove structure is in a Full-ring shape (Full-ring Form), and tapers from the object side of the peripheral portion to the image side or tapers from the image side of the peripheral portion to the object side; by fully annular is meant that the annular groove structure surrounds the optically active portion without breaking; the tapered ring groove structure may have a Taper (Taper), which is generally between 0 degree and 5 degrees if the plastic lens has a release requirement, and may be regarded as a release angle of the ring groove structure. Therefore, the demoulding resistance can be reduced when the plastic lens is separated from the mould after injection molding, so that the quality stability of the plastic lens in the production process is improved, and the problem of poor flatness of the bearing surface of the plastic lens in the injection molding process is further improved; in addition, the tapered annular groove structure makes the plastic lens and the mold less prone to interference.

The at least one annular groove structure has an annular bottom surface. The annular bottom surface extends along a direction substantially perpendicular to the optical axis; wherein, the term substantially perpendicular means that the included angle between the annular bottom surface and the optical axis can be within 10 degrees of 90 degrees of deviation; preferably, the angle may be within 5 degrees of 90 degrees, but not limited thereto. The included angle can be regarded as another release angle of the annular groove structure, and the degree of deflection can be adjusted by matching with the release requirement in the manufacturing process, wherein the angle range from 0 degree to 5 degrees is the angle range with higher general use frequency.

The at least one conical surface is closer to the optically active portion than the annular groove structure. The at least one flat bearing part is closer to the optical effective part than the annular groove structure, and the flat bearing part is in physical contact with an adjacent optical element, wherein the optical element can be a plastic lens, a light shielding plate, a fixed ring or a spacing ring. The at least one full-annular connecting part is connected with the annular groove structure, is far away from the optical effective part compared with the annular groove structure, and defines the depth of the annular groove structure.

The at least one plastic lens and the adjacent optical elements can be assembled correspondingly through the conical surface to align the optical axis. Specifically, the optical element may have a conical surface, and the conical surface of the optical element corresponds to the conical surface of the plastic lens, so that the plastic lens and the optical element can be mutually embedded and assembled to align the core; in addition, the conical surface and the flat bearing part of the plastic lens can be mutually connected to form an axial connecting structure for assembling adjacent optical elements and aligning the optical axis. Therefore, the resolution and the assembly qualification rate of the imaging lens can be improved.

The imaging lens disclosed by the invention can further comprise at least one light shielding plate. The at least one shading plate can be arranged between the plastic lens and another plastic lens adjacent to the image side of the shading plate, and an opening of the shading plate is coaxial with the optical axis; therefore, stray light on a non-imaging path can be shielded, and the imaging quality of the lens is improved. The plastic lens adjacent to the object side of the light shielding plate can have a first conical surface, and the other plastic lens adjacent to the image side of the light shielding plate can have a second conical surface. The first conical surface and the second conical surface are assembled correspondingly to each other and form an accommodating space between the plastic lens and the other plastic lens, and the light shielding plate can be arranged in the accommodating space; therefore, the relative position of the shading plate and the plastic lens can be fixed, so that the assembly tolerance is reduced, and the imaging quality of the imaging lens is improved.

A first distance d from the at least one full-ring-shaped connecting portion to the ring-shaped bottom surface in a direction parallel to the optical axis satisfies the following condition: d is more than or equal to 0.005 mm and less than 0.2 mm. The first distance is the depth of the annular groove structure. Therefore, the depth design value range of the annular groove structure can be adjusted to improve the flatness of the bearing surface of the plastic lens. Wherein the following conditions may also be satisfied: d is more than or equal to 0.01 mm and less than 0.13 mm.

Referring to fig. 7, a schematic diagram of a material injection mark 1325 of the outer peripheral portion 132 of the third lens 130 according to the first embodiment of the present invention is shown, wherein an arrow R1 indicates a flow direction during plastic molding.

The invention provides another imaging lens which is provided with an optical axis and comprises at least one optical element. Wherein, the at least one optical element can be a plastic lens, a fixed ring or a spacing ring.

The at least one optical element comprises a central part and an outer peripheral part in sequence from the center to the periphery. The optical axis passes through the central portion. The peripheral portion surrounds the central portion and includes at least one annular groove structure, at least one conical surface, at least one flat bearing portion and at least one full annular connecting portion on at least one of an object side and an image side of the central portion.

The at least one annular groove structure is in a full ring shape and tapers from the object side to the image side of the outer peripheral portion or from the image side to the object side of the outer peripheral portion. Therefore, the size precision of the optical element in the injection molding process can be improved, and the problem of poor flatness of the bearing surface of the optical element in the injection molding process is solved; furthermore, the annular groove structure having a tapered form may make interference between the optical element and the mold less prone.

The at least one annular groove structure has an annular bottom surface, a first annular sidewall, and a second annular sidewall. The annular bottom surface extends in a direction substantially perpendicular to the optical axis. The included angle between the annular bottom surface and the optical axis can be regarded as a release angle of the annular groove structure, and the deflection degree of the included angle can be adjusted by matching with the release requirement in the manufacturing process, wherein the deflection is 0-5 degrees, which is the angle range with higher general use frequency. The first annular side wall is connected with the annular bottom surface and the full annular connecting part and extends in the direction away from the annular bottom surface. The second annular side wall is connected with the annular bottom surface, is closer to the central part than the annular bottom surface and extends towards the direction far away from the annular bottom surface.

The at least one conical surface is closer to the central portion than the annular groove structure and may also be considered as the second annular sidewall described above. The at least one flat bearing part is closer to the central part than the annular groove structure and is in physical contact with another adjacent optical element, wherein the other optical element can be a plastic lens, a light shielding plate, a fixing ring or a spacing ring. The at least one full annular connecting part is connected with the annular groove structure and is far away from the central part compared with the annular groove structure.

The at least one optical element can be correspondingly assembled with the adjacent plastic lens through the conical surface to align the optical axis. Therefore, the resolution and the assembly qualification rate of the imaging lens can be improved.

The central portion may further comprise a central open cell structure. The central opening structure has a first tapered surface and a second tapered surface surrounding a central portion. The first tapered surface is tapered towards the object side and towards the image side, and the second tapered surface is tapered towards the image side and towards the object side. The first tapered surface intersects the second tapered surface to form a central bore. Therefore, non-imaging light rays generated by reflection of the central opening can be reduced.

The other imaging lens disclosed by the invention can further comprise at least one light shielding plate. The at least one light screen is arranged between the optical element and the plastic lens, and an opening of the light screen is coaxial with the optical axis. Therefore, stray light on a non-imaging path can be shielded, and the imaging quality of the imaging lens is improved.

The minimum diameter of the first annular side wall is Φ a1, the maximum diameter of the second annular side wall is Φ a2, the length of the annular bottom face in the direction perpendicular to the optical axis is (Φ a1- Φ a2)/2, which satisfies the following conditions: 0.005 mm (phi A1-phi A2)/2 is less than 0.2 mm. Therefore, the length design value range of the annular groove structure can be adjusted, and the flatness of the bearing surface of the optical element is improved. Wherein the following conditions may also be satisfied: 0.01 mm (phi A1-phi A2)/2 is less than 0.17 mm. Fig. 8 is a schematic view illustrating a minimum diameter Φ a1 of the first annular sidewall 1421b and a maximum diameter Φ a2 of the second annular sidewall 1421c according to the first embodiment of the invention.

Therefore, the relative positions of the structures of the outer periphery can be defined so as to reduce the size variation of the conical surface. Fig. 8 is a schematic diagram illustrating a maximum outer diameter Φ L of the fourth lens element 140, a minimum diameter Φ a1 of the first annular sidewall 1421b, a maximum diameter Φ a2 of the second annular sidewall 1421C, and a maximum diameter Φ C of the second conical surface 140a according to the first embodiment of the invention.

The maximum outer diameter of the at least one optical element is Φ L, the minimum diameter of the first annular sidewall is Φ a1, and the maximum diameter of the second annular sidewall is Φ a2, which can satisfy the following conditions: 1<[ΦL/(ΦA1-ΦA2)]/π²<50. Therefore, the proportion of the outer diameter of the optical element to the length of the annular groove structure can be adjusted to a more proper design range, so that ideal material injection speed control is achieved. Wherein the following conditions may also be satisfied: 3<[ΦL/(ΦA1-ΦA2)]/π²<15。

The periphery of the at least one optical element can be provided with a material injection mark. The material injection mark is far away from the central part compared with the annular groove structure and is far away from the central part compared with the full-annular connecting part. The material injection mark is not contacted with the annular groove structure, but contacted with the full annular connecting part. Therefore, the annular groove structure can be prevented from being damaged by the knife and the scissors, the annular groove structure is kept in a full ring shape, and the forming quality of the optical element can be improved by the full ring shape compared with a non-full ring shape. Referring to fig. 18, a schematic view of a material injection mark 3035 of the outer peripheral portion 303 of the spacer ring 301a according to the third embodiment of the present invention is shown, wherein an arrow R2 indicates a flow direction during plastic molding.

The invention also provides an imaging lens which is provided with an optical axis and comprises at least one plastic lens.

The at least one annular groove structure is in a full ring shape and tapers from the object side to the image side of the outer peripheral portion or from the image side to the object side of the outer peripheral portion. Therefore, in the process of injection molding of the plastic lens, the problem of poor flatness of the bearing surface of the plastic lens caused by the fact that the fixed side and the movable side are driven by the mold to mutually pull the plastic lens due to mold opening can be improved; in addition, the tapered annular groove structure makes the plastic lens and the mold less prone to interference.

The at least one annular groove structure has at least one annular bottom surface and at least one annular top surface. The annular bottom surface extends in a direction substantially perpendicular to the optical axis. The annular top face extends in a direction substantially perpendicular to the optical axis. The included angle between the annular bottom surface and the optical axis can be regarded as a release angle of the annular groove structure, and the degree of deflection can be adjusted by matching with the release requirement in the manufacturing process, wherein 0-5 degrees is an angle range with higher general use frequency.

The at least one annular groove structure may further have a first annular sidewall and a second annular sidewall. The first annular side wall is connected with the annular bottom surface and the full annular connecting part and extends in the direction away from the annular bottom surface. The second annular side wall is connected with the annular bottom surface, is closer to the optical effective part than the annular bottom surface and extends towards the direction far away from the annular bottom surface.

The at least one full annular connecting part is connected with the annular groove structure and is far away from the optical effective part compared with the annular groove structure.

The periphery of the at least one plastic lens is provided with a material injection mark. The material injection mark is far away from the optical effective part compared with the annular groove structure, and is far away from the optical effective part compared with the full-annular connecting part. Therefore, the annular groove structure can be prevented from being damaged by the knife and the scissors, the annular groove structure is kept in a full ring shape, and the forming quality of the plastic lens can be improved by the full ring shape compared with a non-full ring shape.

The number of the at least one annular bottom surface is Nb, and the number of the at least one annular top surface is Nt, which may satisfy the following condition: nb ═ Nt + 1. Therefore, the proper number range of the annular groove structures can be defined to be adjusted according to the quality requirement of the plastic lens in the manufacturing process.

A first distance d from the at least one full-ring-shaped connecting portion to the ring-shaped bottom surface in a direction parallel to the optical axis, a minimum diameter of the first ring-shaped side wall is Φ a1, a maximum diameter of the second ring-shaped side wall is Φ a2, and a length of the ring-shaped bottom surface in a direction perpendicular to the optical axis is (Φ a1- Φ a2)/2, which may satisfy the following conditions: 0.2<2d/(Φ A1- Φ A2) < 5.0. Therefore, the phenomenon that the over-deep annular groove structure blocks the uniformity of plastic fluid perfusion can be avoided, and the phenomenon that the over-long and over-shallow annular groove structure loses the function of adjusting plastic perfusion can be avoided. Wherein the following conditions may also be satisfied: 0.3<2d/(Φ A1- Φ A2) < 3.33. Through the better numerical range, the adjustment margin of the technological parameters of the die production can be improved, and the production process has more flexible adjustment space.
