To solve the above technical problem, please refer to fig. 2-6, a first aspect of the present application provides a lens barrel 300 for a camera module, wherein the lens barrel 300 has various coating colors in appearance, and can meet the requirement of consumers for diversification of the appearance color of the camera module. In this embodiment, the lens barrel 300 for a camera module includes a substrate layer 100, a color-changing film 200, and a barrel body.
The camera module is used for shooting an object, and for convenience of description, an end portion or an end surface of the camera module close to one side of the object is defined as an object side end or an object side surface of the camera module, and an end portion or an end surface of the camera module away from one side of the object is defined as an image side end or an image side surface of the camera module.
Referring to fig. 2-3, the barrel defines an optical axis, and light reflected by the object passes through the barrel from an object side end of the barrel to an image side end of the barrel and reaches an image side end of the barrel. The cylindrical body includes a cylindrical peripheral wall 311 disposed around the optical axis and a cylindrical side wall 312 connected to an object side end of the cylindrical peripheral wall 311. The outer edge of the cylinder side wall 312 is connected to the inner edge of the object side end of the cylinder side wall 311, and the cylinder side wall 311 and the cylinder side wall 312 together define a housing chamber in which a lens 320 is disposed perpendicularly to the optical axis.
The cylinder side wall 312 has an annular object side wall surface 313 close to the subject. The object-side wall surface 313 may be a square ring or a circular ring. It should be noted that the shape of the object side wall surface 313 is not limited to the square ring shape or circular ring shape in the present embodiment, and may be determined according to the shape of the cylinder side wall 312 of the actual cylinder. The object-side wall surface 313 may include a second annular surface 3132 disposed obliquely to the image-side direction around the optical axis and a first annular surface 3131 disposed perpendicularly to the optical axis, an outer edge of the second annular surface 3132 being connected to an inner edge of the first annular surface 3131. The first annular surface 3131 has a light entrance port penetrating the accommodation chamber, and external light passes through the lens 320 through the light entrance port 314 and irradiates the image side surface of the lens 320.
In this embodiment, the substrate layer 100 is provided on the object-side wall surface 313 of the cylinder sidewall 312, and the substrate layer 100 has light transmittance. The base layer 100 may be fixed to the object-side wall surface 313 of the cylinder sidewall 312 by an adhesive, may be fixed to the object-side wall surface 313 of the cylinder sidewall 312 by stamping, or may be fixed to the object-side wall surface 313 of the cylinder sidewall 312 by plating. The material of the substrate layer 100 may be any material that can be made into the lens barrel 300, such as plastic, glass, metal, and the like.
In order to enhance the connection stability between the substrate layer 100 and the object side wall surface 313 of the cylinder side wall 312, the substrate layer 100 may fully cover the object side wall surface 313 of the cylinder side wall 312 or may partially cover the object side wall surface 313 of the cylinder side wall 312, in order that the substrate layer 100 supports the color changing film 200. For example, when the object-side wall surface 313 of the cylinder sidewall 312 includes the first annular surface 3131 and the second annular surface 3132, the substrate layer 100 may cover only the first annular surface 3131, only the second annular surface 3132, or both the first annular surface 3131 and the second annular surface 3132. Meanwhile, the appearance color of the lens barrel 300 of the camera module is uniformly distributed, and the visual experience of a user is enhanced.
In this embodiment, the surface of the substrate layer 100 facing away from the object-side wall surface 313 of the cylinder sidewall 312 is provided with the color-changing film 200, that is, the substrate layer 100 bears the color-changing film 200. The color-changing film 200 can be connected with the substrate layer 100 in a spray printing manner, can also be connected with the substrate layer 100 through an adhesive, and can also be connected with the substrate layer 100 in a stamping manner.
The size of the exposed area of the color changing film 200 determines the distribution of the appearance color of the lens barrel 300 of the camera module, and in order to enhance the uniformity of the distribution of the appearance color of the lens barrel 300 of the camera module and improve the visual experience of the user, the color changing film 200 preferably completely covers the surface of the substrate layer 100 facing away from the object-side wall surface 313 of the barrel side wall 312.
In this embodiment, the color-changing film 200 includes a base layer 210 and a photochromic layer 220 that are stacked on each other.
The base layer 210 has a specific initial color, which may be color developing. For example, the substrate layer 210 may be one of red, orange, yellow, green, cyan, blue, violet, etc. or other mixed colors (e.g., pink). The type of the substrate layer 210 may be one of an anti-reflection layer, a gradient color layer, or the like.
When the substrate layer 210 is an anti-reflection layer, the anti-reflection layer utilizes the principle of light interference to make light reflected by two opposite surfaces of the anti-reflection layer interfere with each other to increase the transmittance of light. The anti-reflection layer can be made of SiO2Film layer, Ti3O5The films are laminated. When the base layer 210 is a reflective layer, it is reflectiveThe reflective layer reflects different colors according to different wavelengths of different lights and has different reflectivity. The reflective layer may be made of MgF of a low refractive index material2Film layer, SiO2The film layers are stacked and can also be made of M of medium refractive index material2Film layer, Al2O3The film layers are stacked and can also be made of H of high-refractive-index material4Film layer, Ta2O5Film layer, Nb2O5The film layer and the OS-50 film layer are stacked. The material of the film layer of the gradient layer may be the same as that of the reflective layer, and is not described herein.
The photochromic layer 220 mainly functions as a substrate, and the photochromic layer 220 may show different colors according to the different irradiation intensities of the ultraviolet rays in the external irradiation light. Specifically, the photochromic layer 220 has an initial color of an approximately transparent colorless state after the photochromic layer 220 is plated under the condition that no external light is irradiated. Under the condition that the external light irradiates on the photochromic layer 220, the ultraviolet rays in the external light cause the photochromic layer 220 to generate a chemical reaction, and the photochromic layer 220 is changed into grey and black from an initial transparent state.
The material of the photochromic layer 220 may be WO3、MOO3、Ag3VO4.Ag3SiO4.Ag3PO4AgBr-CuBr, AgCl-CuCl and the like. The coating process of the photochromic layer 220 may be vacuum evaporation, sputtering, electron beam evaporation, electrodeposition, spray pyrolysis, sol-gel method, or the like. The sol-gel method has the advantages of being capable of preparing materials with different crystal forms and different compactness degrees, easily controlling the composition and the grain diameter of a product, easily producing uniform films in a large area and the like. When the material of the photochromic layer 220 is WO3When the photochromic layer 220 is changed from colorless to gray and black, the condition is that the wavelength of light is light<450 nm. When the material of the photochromic layer 220 is MOO3In this case, the photochromic layer 220 is changed from colorless to gray and black under the irradiation of ultraviolet rays. When the material of the photochromic layer 220 is Ag3VO4.Ag3SiO4.Ag3PO4When the photochromic layer 220 is onUnder the irradiation condition of light, the color of the paint can be changed from grey to black. When the material of the photochromic layer 220 is AgBr — CuBr, the photochromic layer 220 changes from colorless to gray and black under the irradiation condition of the Xe lamp. When the material of the photochromic layer 220 is AgCl — CuCl, the photochromic layer 220 changes from colorless to gray and black under the irradiation of ultraviolet rays.
In this embodiment, the color of the color-changing film 200 is formed by superimposing the color of the photochromic layer 220 and the color of the base layer 210. For example, under the condition that the photochromic layer 220 is not irradiated by external light, the color of the base layer 210 is light green, and the photochromic layer 220 is approximately in a transparent colorless state after being plated, that is, the color of the photochromic film 200 is light green formed by overlapping the light green of the base layer 210 and the transparent colorless of the photochromic layer 220. Under the condition that the photochromic layer 220 is irradiated by external light, the base layer 210 is light green, the photochromic layer 220 is chemically reacted and changed into gray and black from transparent, that is, at this time, the color of the photochromic film 200 is the superposition of the light green of the base layer 210 and the gray of the photochromic layer 220 after the reaction, or the color of the photochromic film 200 is dark green formed by the superposition of the light green of the base layer 210 and the black of the photochromic layer 220 after the reaction. The color-changing film 200 is changed from light green to dark green after being irradiated by ultraviolet rays in external irradiation light, so that the color of the color-changing film 200 is changed, and the diversified requirements of the appearance color of the cylinder side wall 312 of the cylinder body are met.
The stacking manner between the base layer 210 and the photochromic layer 220 is arbitrary.
For example, as shown in fig. 4, the photochromic layer 220 may be disposed on a surface of the substrate layer 100 facing away from the object-side wall surface 313 of the cylinder sidewall 312, and the base layer 210 is correspondingly disposed on a surface of the photochromic layer 220 facing away from the substrate layer 100. The photochromic layer 220 may be attached to the surface of the substrate layer 100 away from the object-side wall surface 313 of the cylinder sidewall 312 by spraying, or the photochromic layer 220 may be attached to the surface of the substrate layer 100 away from the object-side wall surface 313 of the cylinder sidewall 312 by gluing with an adhesive. The base layer 210 may be attached to the surface of the photochromic layer 220 away from the base layer 100 by spraying, or the base layer 210 may be attached to the surface of the photochromic layer 220 away from the base layer 100 by gluing with an adhesive.
At this time, the base layer 210 may be one of an anti-reflection layer, a gradation layer, or the like. When the substrate layer 210 is an anti-reflection layer, the anti-reflection layer may be made of SiO2Film 210a, Ti3O5The film 210b is laminated. Referring to FIG. 4, the anti-reflection layer includes four SiO layers2Film 210a and four layers of Ti3O5Film 210b, four layers of SiO2Film 210a and four layers of Ti3O5The films 210b are alternately stacked in this order. Wherein, the Ti of the anti-reflection layer is positioned at the outer side3O5The film 210b is attached to the surface of the photochromic layer 220 facing away from the substrate layer 100.
The base layer 210 can be freely adjusted to be red, orange, yellow, green, cyan, blue, purple or any other mixed color, the photochromic layer 220 is plated with the initial color to be in an approximately transparent colorless state, and the lens barrel 300 of the camera module only displays the color (for example, green) of the base layer 210. Under the condition that the external irradiation light irradiates the object side wall surface 313 of the barrel side wall 312 from the object side, the photochromic layer 220 undergoes a chemical reaction and changes from transparent to gray and black, and at this time, the appearance color of the lens barrel of the camera module is the color obtained by overlapping the substrate layer 210 and the photochromic layer 220 (for example, the color obtained by overlapping green and gray, and the color obtained by overlapping green and black are dark green), so that the effect of changing the appearance of the lens barrel 300 of the camera module is achieved.
For example, as shown in fig. 5, the base layer 210 may be disposed on the surface of the substrate layer 100 facing away from the object-side wall surface 313 of the cylinder sidewall 312, and the photochromic layer 220 may be correspondingly disposed on the surface of the base layer 210 facing away from the substrate layer 100. The connection modes between the base layer 210 and the substrate layer 100 and between the photochromic layer 220 and the base layer 210 may be the same as those described above, and are not described herein again.
In this case, the base layer 210 may be one of an antireflection layer, a reflective layer, a gradient color layer, and the like. When the substrate layer 210 is an anti-reflection layer, the chemical composition of the anti-reflection layer may be the same as that described above, and will not be described herein. Referring to FIG. 5, the anti-reflection layer includes four SiO layers2Film 210a and four layers of Ti3O5Film 210b, four layers of SiO2Film 210a andfour layers of Ti3O5The films 210b are alternately stacked in this order. Wherein, the Ti of the anti-reflection layer is positioned at the outer side3O5The film 210b is attached to the surface of the object side wall surface 313 of the substrate layer 100 away from the barrel sidewall 312, and the photochromic layer 220 is attached to the SiO layer on the outer side of the antireflection layer2The surface of film 210 a.
It should be noted that no matter what stacking manner is used between the base layer 210 and the photochromic layer 220 to form the photochromic film 200, the principle of color superposition between the base layer 210 and the photochromic layer 220 is not changed. Therefore, when the base layer 210 and the photochromic layer 220 are stacked in the manner shown in fig. 5, the color change principle is the same as that when the base layer 210 and the photochromic layer 220 are stacked in the manner shown in fig. 4, and the description thereof is omitted.
Referring to fig. 6, when the base layer 210 is disposed on the surface of the substrate layer 100 away from the object-side wall surface 313 of the cylinder 312, the base layer 210 may further include a first layer 211 and a second layer 212, and the photochromic layer 220 is correspondingly disposed between the first layer 211 and the second layer 212.
The first layer 211 may be attached to the surface of the object-side wall surface 313 of the substrate layer 100 away from the cylinder sidewall 312, at this time, the photochromic layer 220 is correspondingly attached to the surface of the first layer 211 away from the substrate layer 100, and the second layer 212 is correspondingly attached to the surface of the photochromic layer 220 away from the first layer 211. The connection modes between the first layer 211 and the substrate layer 100, between the photochromic layer 220 and the first layer 211, and between the second layer 212 and the photochromic layer 220 are the same as above, and are not described herein again.
In this case, the first layer 211 and the second layer 212 may be one of an anti-reflection layer, a gradient color layer, or the like. When the first layer 211 and the second layer 212 are both anti-reflection layers, the anti-reflection layer may be made of SiO2Film 211a, Ti3O5The film 211b is laminated. Referring to FIG. 6, the first layer 211 comprises two layers of SiO2Film 211a and two layers of Ti3O5Film 211b, two layers of SiO2Film 211a and two layers of Ti3O5The films 211b are alternately laminated in sequence, and the second layer 212 also includes two layers of SiO2Film 212a and two layers of Ti3O5Film 212b, two layers of SiO2Film 212a and two layers of Ti3O5The films 212b are also alternately stacked in this order. Wherein, the Ti of the first layer 211 is located at the outer side3O5The film 211b is attached to the object side wall surface 313 of the substrate layer 100 away from the cylinder side wall 312, and the Ti of the second layer 212 located on the outer side3O5The film 212b is applied to the outer SiO layer of the photochromic layer 220 facing away from the first layer 2112The surface of the membrane.
