The invention provides a camera module, which comprises a lens assembly and a base, wherein the base comprises a lens bearing part, an optical filter bearing part and a cylindrical part; the optical filter supporting portion is made of a metal material and is integrally formed with the lens receiving portion and the cylindrical portion through an integral molding process.
Description
Technical Field
The invention relates to the field of camera modules, in particular to a novel camera module.
Background
Currently, a camera module generally includes a lens assembly and a base, and the lens assembly further includes a bracket for mounting a camera. Currently, more and more camera modules adopt double cameras, such as mobile phones, and more mobile phones adopt double cameras, so that photographing functions and effects are improved. This means that the stand will carry a double camera.
In the prior art, the bracket and the base are made of plastic, and are directly molded by mold opening and injection molding, so that the plastic product has natural defects related to the material thereof, such as water absorption expansion problem, and the reliability is affected; the density is little, and intensity is not enough, and easy deformation influences the module optical axis degree. At the same time, as the market is increasingly pursuing lighter electronic devices, lightweight, small-sized modules are becoming more popular. However, for the bracket and the base made of plastics in the prior art, if the thickness of the bracket and the base is reduced, the strength of the base is poor after the base is thinned, the base is easy to deform, the flatness is also poor, and the design requirement of the die set is not met. The support is poor in strength, easy to deform and poor in flatness after being thinned, and the coaxiality of the double-shot optical axis is particularly affected for the double-shot support. If the plastic is changed into metal to form a metal bracket and a base, the metal bracket and the base are made of metal materials, and the metal bracket and the base are easy to thin and small in volume, but compared with the plastic, the metal bracket and the base have the defect of natural metal, such as heavy weight, and the weight of the whole module is increased; the price is high, resulting in excessive cost; metal working is limited, and surface treatment is difficult, and appearance is affected, etc.
Therefore, there is a need to provide a module component that is light, thin, small, and reliable in strength, and that solves the above-mentioned technical problems.
Disclosure of Invention
In order to solve the technical problems in the prior art, the invention provides the camera module, which can further reduce the size of the module and improve the strength and reliability of the module compared with the prior art. The camera module comprises a lens assembly and a base, wherein the base comprises a lens bearing part, an optical filter bearing part and a cylindrical part; the optical filter supporting portion is made of a metal material and is integrally formed with the lens receiving portion and the cylindrical portion through an integral molding process. The filter support part is made of metal material, so that the strength of the filter support part can be ensured, the thickness of the metal filter support part can be further reduced, and preferably, the thickness of the filter support part can be reduced to 0.05-0.15mm, and the distance (back focus) from a lens to a filter can reach 0.12mm.
Preferably, the filter supporting part is black, so that light reflection at the chamfer positions of the base around the light passing hole of the base is avoided.
Preferably, the metal material constituting the filter support portion is subjected to a nano-treatment. The nanometer treatment is to carry out nanometer treatment on the metal material in advance before the metal material is injection molded, and the holes are nanometer-level micro holes, so that the contact area between the punched metal material and the plastic material can be increased when the punched metal material is injection molded, the adhesive force of the contact surface between the punched metal material and the plastic material is increased, and the stability of the base after the integrated molding is further improved.
Preferably, the lens assembly comprises a lens bracket for installing double cameras, the lens bracket is of a cuboid frame structure comprising an upper surface, a lower surface, an inner surface and an outer surface, a bracket body of the lens bracket comprises a metal framework and a plastic framework integrally formed with the metal framework, and the bracket body is provided with two hollowed-out parts for installing the camera assembly and reinforcing ribs arranged between the two hollowed-out parts.
Preferably, the aforementioned process of forming into one body is an insert molding process.
Preferably, the metal frameworks are arranged between the plastic frameworks, so that the plastic frameworks surround the upper surface, the lower surface and the outer surface of the metal frameworks, and the metal frameworks are only exposed on the inner surface of the cuboid frame structure. The metal material is embedded in the plastic material, no metal is exposed out of the outer surface of the frame of the bracket, and the metal is exposed out of the inner surface of the frame.
Preferably, the metal skeleton is disposed within and completely surrounded by the plastic skeleton.
Preferably, the metal skeleton is arranged on the upper part of the plastic skeleton. The plastic material is embedded in the metal material, the outer surface of the frame of the bracket is exposed by metal, and the inner surface is not exposed by metal.
Because the base and the bracket are both provided with a part of metal materials embedded therein, the combination of metal and plastic further reduces the water absorption expansion rate of plastic compared with the whole plastic material, improves the heat dissipation effect of the base, improves the affinity between the bearing surface and the glue, and further improves the flatness of the bearing surface.
The invention has the beneficial effects of further reducing the volume of the module, improving the overall heat dissipation effect of the module while ensuring the strength of the module, reducing the water absorption expansion rate of the module in a high-temperature and high-humidity environment and improving the stability of the resolution of the module in the high-temperature and high-humidity environment.
