The lens assembly 100 includes a lens barrel 10 and a lens 20.

The lens barrel 10 according to the embodiment of the present application is described below with reference to the drawings.

As shown in fig. 1 and 2, a lens barrel 10 according to an embodiment of the present application includes a side wall 1 and a top wall 2.

Specifically, the side wall 1 is formed in a ring shape, the side wall 1 defines a housing chamber 11, the top wall 2 is connected to one end of the side wall 1, the top wall 2 has a light transmission hole 24 communicating with the housing chamber 11, and the top wall 2 has a top surface 23 and a connection surface 22 connecting the top surface 23 and an inner surface 21 of the light transmission hole 24. It will be appreciated that the inner surface 21, the connecting surface 22 and the top surface 23 of the light-transmitting hole 24 are sequentially disposed in a radially outward direction of the light-transmitting hole 24, the top surface 23 is disposed away from the light-transmitting hole 24, and the connecting surface 22 is disposed between the inner surface 21 and the top surface 23 of the light-transmitting hole 24. As shown in fig. 1 and 2, the width of the inner surface 21 and the top surface 23 of the light transmission hole 24 in the radial direction of the light transmission hole 24 is small, and the width of the connection surface 22 in the radial direction of the light transmission hole 24 is larger than the width of the inner surface 21 and the top surface 23 of the light transmission hole 24 in the radial direction of the light transmission hole 24.

As shown in fig. 2 and 4, the connecting surface 22 is provided with a plurality of first protrusions 3, each first protrusion 3 is disposed around the optical axis, and any two adjacent first protrusions 3 are disposed at an interval. It is understood that each first protrusion 3 extends in a ring shape along the circumferential direction of the light-transmitting hole 24, and the plurality of first protrusions 3 are arranged at intervals in the direction from the inner surface 21 to the top surface 23 of the light-transmitting hole 24. Wherein the longitudinal section of each first projection 3 is formed in a triangular shape. Two surfaces of the first protrusion 3 spaced in the radial direction of the light hole 24 are respectively configured as a first reflection plane 31 and a second reflection plane 32, after light rays irradiate the first reflection plane 31 and the second reflection plane 32 along the direction parallel to the optical axis of the light hole 24, the light rays are reflected to the surface of the other first protrusion 3 opposite to the first protrusion for at least one time and then reflected for the second time, the energy of the light rays is weakened in the process of being reflected, the energy of the reflected light rays is small, the viewed light energy is small, the blackening effect is realized, and the super-black effect is achieved. In addition, the longitudinal section of the first protrusion 3 is triangular, so that the light rays irradiated to the top surface of the first protrusion 3 can be prevented from being directly reflected, and the blackening effect is ensured.

In the description of the present application, it is to be understood that the terms "inner", "outer", "axial", "radial", "circumferential", and the like, as used herein, refer to an orientation or positional relationship as shown in the drawings, which is for convenience and simplicity of description only, and does not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus is not to be considered as limiting. In the description of the present application, "a plurality" means two or more unless otherwise specified.

The first protrusion 3 and the lens barrel 10 can be directly formed by die processing, so that the processing procedure of the first protrusion 3 can be simplified, and the assembly efficiency can be improved. In addition, the mould of this application is through super finish turning or accurate CNC processing, and the mould work piece surface after the processing will reach the mirror surface level.

The angle between the first reflection plane 31 and the second reflection plane 32 is α, and when α is less than or equal to 60 °, as shown in fig. 9, the light beam is emitted to the first reflection plane 31 on one first protrusion 3 and then reflected once to the second reflection plane 32 of the adjacent first protrusion 3, at this time, the angle between the light beam and the second reflection plane 32 of the first protrusion 3 is less than or equal to 90 °, which means that the reflected light beam is reflected twice again toward the first reflection plane 31 of the first protrusion 3 into which the light beam is emitted and is reflected toward the direction close to the accommodating cavity 11. The more the light reflection times are, the larger the energy loss is, the weaker the reflected light is, the blacker the light looks like, and the blackening effect is better.

For example, as shown in fig. 9, when the angle between the first reflecting plane 31 and the second reflecting plane 32 is 50 °, the light is reflected by three reflections; as shown in fig. 10, when the angle between the first reflection plane 31 and the second reflection plane 32 is 70 °, the light is reflected twice, the energy loss of the third reflection is greater, the reflected light is less, and the visual effect is darker.

Preferably, the first protrusion 3 has a first reflection plane 31 and a second reflection plane 32 spaced apart in a radial direction of the light transmission hole 24, an angle between the first reflection plane 31 and the second reflection plane 32 being α, α satisfying: alpha is less than or equal to 60 degrees. Therefore, the reflection times of the light can be increased, and the blackening effect is improved.

According to the lens barrel 10 of the embodiment of the application, the plurality of first protrusions 3 are arranged on the connecting surface 22, each first protrusion 3 extends in the circumferential direction of the light hole 24 to form a ring shape, the plurality of first protrusions 3 are arranged at intervals in the radial direction of the light hole 24, the longitudinal section of each first protrusion 3 is triangular, two surfaces of each first protrusion 3 spaced in the radial direction of the light hole 24 are respectively configured into the first reflecting plane 31 and the second reflecting plane 32, light rays emitted to the first reflecting plane 31 and the second reflecting plane 32 in the optical axis direction of the light hole 24 can be reflected at least twice, the energy of the reflected light rays can be weakened, and the blackening effect is achieved. In addition, the longitudinal section of the first protrusion 3 is triangular, so that the light rays irradiated to the top surface of the first protrusion 3 can be prevented from being directly reflected, and the blackening effect is ensured.

In some embodiments of the present application, the connection surface 22 is a plane perpendicular to the optical axis of the light-transmissive hole 24. Thereby, the structure of the lens barrel 10 can be simplified, and the arrangement of the plurality of first protrusions 3 is facilitated.

Of course, the present application is not limited thereto, as shown in fig. 1 to 4, the connecting surface 22 includes a plurality of sub-surfaces 221 perpendicular to the optical axis of the light-transmitting hole 24, the plurality of sub-surfaces 221 are disposed around the optical axis and spaced apart from each other along the optical axis, and each sub-surface 221 has at least one first protrusion 3 thereon. Specifically, the plurality of sub-surfaces 221 are sequentially arranged in the direction from the inner surface 21 to the top surface 23 of the light transmission hole 24, any two adjacent sub-surfaces 221 have a height difference in the direction of the optical axis of the light transmission hole 24, the sub-surface 221, which is close to the optical axis of the light transmission hole 24, of the two adjacent sub-surfaces 221 is closer to the accommodating cavity 11, and each sub-surface 221 is provided with at least one first protrusion 3. Therefore, the structure of the lens barrel 10 can be better adapted, the structure of the camera module 200 is more compact, and in addition, the light is conveniently guided into the light hole 24.

Further, as shown in fig. 4 and 5, the height difference between the two sub-surfaces 221 is 0.02-0.5 mm. For example, the height difference between the two adjacent sub-surfaces 221 is 0.05mm, 0.1mm, 0.15mm, 0.20mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, or 0.45mm, etc. The arrangement of the first protrusions 3 is convenient, the reflection of light is convenient, and the blackening effect is better realized.

As shown in fig. 5, two adjacent sub-surfaces 221 are connected by the sub-connection surface 222, and the grooves 33 are formed between two adjacent first protrusions 3 on the same sub-surface 221 and between the first protrusion 3 and the adjacent sub-connection surface 222. Therefore, the light rays irradiated on the sub-connection surface 222 and the surface of the first protrusion 3 (the first reflection plane 31 and the second reflection plane 32) can be reflected out through at least two reflections, and the blackening effect is ensured.

In addition, when the connection surface 22 is a plane perpendicular to the optical axis of the light-transmitting hole 24, the connection surface 22 is provided with a plurality of first protrusions 3, a groove 33 is formed between two adjacent first protrusions 3 of the plurality of first protrusions 3, and the groove 33 is formed between a first protrusion 3 of the plurality of first protrusions 3 close to the top surface 23 and a surface (a connection surface between the top surface 23 and the connection surface 22) adjacent to the first protrusion 3 in the radial direction of the light-transmitting hole 24.

As shown in fig. 5, the longitudinal section of the groove 33 may be triangular, so that all the light rays irradiated into the groove 33 can be reflected out after being reflected at least twice by the first and second reflection planes 31 and 32, thereby improving the blackening effect.

Of course, the present application is not limited thereto, and as shown in fig. 5, the shape of the longitudinal section of the groove 33 may be trapezoidal, that is, the bottom wall of the groove 33 may also be a plane perpendicular to the optical axis of the light-transmitting hole 24, and when the bottom wall of the groove 33 is a plane perpendicular to the optical axis of the light-transmitting hole 24, the width of the bottom wall of the groove 33 in the radial direction of the light-transmitting hole 24 is 0.003-0.3 mm. For example, the width of the bottom wall of the groove 33 in the radial direction of the light transmission hole 24 may be 0.01mm, 0.05mm, 0.1mm, 0.15mm, 0.2mm, 0.25mm, or the like. Therefore, the width of the bottom wall of the groove 33 in the radial direction of the light hole 24 is prevented from being too large, more light rays are directly reflected out when being irradiated to the bottom wall of the groove 33, the blackening effect is not reduced through multiple reflection, and the blackening effect of the lens assembly 100 is ensured.

In the description of the present application, it is to be understood that the terms "length", "width", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.

Of course, the present application is not limited thereto, and as shown in fig. 5, the bottom wall of the groove 33 is an arc-shaped surface that is concave toward the direction of the accommodating chamber 11, and when the bottom wall of the groove 33 is an arc-shaped surface that is concave toward the direction of the accommodating chamber 11, the radius of the cylinder where the bottom wall of the groove 33 is located is 0.002-0.3 mm. For example, the radius of the cylinder in which the bottom wall of the groove 33 is located may be 0.01mm, 0.05mm, 0.1mm, 0.15mm, 0.2mm, 0.25mm, or the like. The radius of the cylinder at the bottom wall of the groove 33 is prevented from being too large, more light rays are directly reflected out when irradiating the bottom wall of the groove 33, the blackening effect is reduced without multiple reflections, and the blackening effect of the lens assembly 100 is guaranteed.

In some embodiments of the present application, as shown in fig. 6 to 8, the connection face 22 is inclined in a radially outward direction of the light-transmitting hole 24 in the light outgoing direction of the optical axis. The structure of the lens barrel 10 can thereby be simplified, and light can be easily guided to the light-transmitting hole 24. A groove 33 is formed between two adjacent first protrusions 3, and the bottom wall of the groove 33 is a plane. This can further simplify the structure of the lens barrel 10.

Further, the bottom wall of the groove 33 is a plane perpendicular to the optical axis of the light-transmitting hole 24. Thereby, the structure of the lens barrel 10 can be further simplified.

As shown in fig. 6 to 8, a groove 33 is formed between two adjacent first protrusions 3, a plurality of second protrusions 4 spaced apart along the circumferential direction of the light-transmitting hole 24 are disposed in each groove 33, and the distance between two adjacent second protrusions 4 increases gradually in the light outgoing direction of the optical axis. Specifically, two ends of the second protrusion 4 are respectively connected to two adjacent first protrusions 3, the second protrusion 4 includes a third reflection plane 41 and a fourth reflection plane 42 spaced apart in the circumferential direction of the light transmission hole 24, one ends of the third reflection plane 41 and the fourth reflection plane 42 far away from the accommodating cavity 11 are directly connected, and the distance between the third reflection plane 41 and the fourth reflection plane 42 gradually increases in the direction toward the accommodating cavity 11. Therefore, the diversity of the structure of the lens barrel 10 can be increased, in addition, the third reflection plane 41 and the fourth reflection plane 42 can reflect the light rays emitted to the third reflection plane 41 and the fourth reflection plane 42, when the distance between the third reflection plane 41 and the fourth reflection plane 42 on two adjacent second bulges 4 is short, the light rays emitted to the third reflection plane 41 and the fourth reflection plane 42 can be reflected at least twice, and the blackening effect is improved.

Further, as shown in fig. 7 and 8, the bottom wall of the sub-groove 43 defined between two adjacent first protrusions 3 and two adjacent second protrusions 4 is a rectangular plane, and the length and width of the bottom wall of the sub-groove 43 are both 0.003-0.5 mm. It can be understood that the length and width of the bottom wall of the sub-groove 43 are both 0.003-0.5mm, for example, the length and width of the bottom wall of the sub-groove 43 can be 0.119mm and 0.010mm, respectively, so that the area of the bottom wall of the sub-groove 43 can be reduced, and partial light rays are prevented from being directly reflected out after being irradiated onto the bottom wall of the sub-groove 43, thereby reducing the blackening effect.

As shown in fig. 4, the top surface 23 is perpendicular to the optical axis of the light-transmissive hole 24. Thereby facilitating the mounting of the lens barrel 10. Further, a plurality of first protrusions 3 are provided on the top surface 23. Thereby further increasing the blackening effect of the lens assembly 100. It is understood that a plurality of first protrusions 3 may be disposed on the top surface 23, each first protrusion 3 extends in a ring shape along the circumferential direction of the light-transmitting hole 24, and the plurality of first protrusions 3 are arranged at intervals along the radial direction of the light-transmitting hole 24.

When the top surface 23 and the connecting surface 22 are both planes perpendicular to the optical axis of the light-transmitting hole 24, the connecting surface 22 and the top surface 23 may be coplanar, and certainly, the connecting surface 22 and the top surface 23 may also form a step surface, and the height of the connecting surface 22 is lower than that of the top surface 23.

Alternatively, the distance between adjacent two first protrusions 3 of the plurality of first protrusions 3 on the same surface is 0.02 to 0.5 mm. For example, it may be 0.05mm, 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm, or the like. Therefore, the light rays covered on the surface of the first protrusion 3 can be better reflected out after being reflected at least twice, and the blackening effect is improved.

Optionally, the height of the first protrusions 3 is 0.02-0.5 mm. For example, the height of the first protrusion 3 is 0.05mm, 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, or 0.45mm, etc., so that it is ensured that the light irradiated on the surface of the first protrusion 3 can be reflected at least twice, the blackening effect is improved, and the appearance effect of the lens barrel 10 can be ensured.

Alternatively, the first and second reflecting

planes

31 and 32 are at the same angle to the optical axis of the light-transmissive hole 24. It can be understood that the longitudinal section of the first protrusion 3 may be an isosceles triangle, so that it can be ensured that the light rays reflected onto the first reflection plane 31 and the second reflection plane 32 can be reflected out at the same angle, and the uniformity of the blackening effect can be ensured.

Alternatively, the plurality of first protrusions 3 on the same surface are the same in shape and size. Whereby the uniformity of the blackening effect of the lens assembly 100 can be further enhanced.

Alternatively, the plurality of first protrusions 3 on the same surface are uniformly distributed in the radial direction of the light-transmitting hole 24. Whereby the uniformity of the blackening effect of the lens assembly 100 can be further enhanced.

As shown in fig. 4, the inner surface 21 of the light-transmitting hole 24 is inclined in the direction of the side wall 1 to the top wall 2 toward the radially outward direction of the light-transmitting hole 24. Therefore, light can be guided into the light holes 24, and the shooting effect of the camera module 200 is improved. Further, the width of the inner surface 21 of the light transmission hole 24 in the radial direction of the light transmission hole 24 is generally within 0.2mm, and the first projection 3 is not generally provided on the inner surface 21 of the light transmission hole 24.

Alternatively, the side wall 1 of the lens barrel 10 is circular, but the present application is not limited thereto, and the side wall 1 of the lens barrel 10 may also be square ring-shaped, etc.

The lens assembly 100 according to an embodiment of the present application is described below.

The lens assembly 100 according to the embodiment of the present application includes the lens 20 and the lens barrel 10, and the lens 20 is disposed in the accommodating chamber 11 and is opposite to the light transmission hole 24.
