Description

A surface coating structure of an electronic device housing

technical field

The utility model relates to electrics, in particular to a surface covering structure of an electronic device shell, especially a surface covering structure of an electronic device shell that makes the surface of an object have a highly dense metal texture.

Background technique

The shells of general electronic devices are mostly made of plastic, but the plastic material is visually and poorly textured. In order to make the plastic shells of electronic devices have a metallic texture, plastic plating is used to deposit a metal on the surface of the plastic shells. layer metal layer, such as the invention of US Patent No. 6,045,866. The metal layer plated by the plastic electroplating method used can only be relatively inactive metals such as copper and nickel, and it is difficult to use more active metals such as aluminum in the plastic electroplating method. Moreover, the steps of the plastic electroplating method itself are relatively complicated and cumbersome, so that the production efficiency is low and the cost is high. Therefore, in order to improve the texture of the electronic device casing, the industry has abandoned the use of plastic as the casing of electronic products, and has developed metal materials such as aluminum, magnesium, or aluminum-magnesium alloys as electronic device casings. Shells, to enhance the quality of products, have been widely used in various electronic devices, such as mobile phone shells or PDA shells.

When the above-mentioned electronic device casing is in use, there are the following problems and deficiencies that need to be improved:

When aluminum, magnesium, or aluminum-magnesium alloy is used as the housing material of electronic devices, although the texture of the product is improved, due to the characteristics of the metal material, the surface gives people a cold touch, there is no pattern on the surface, and the color is too monotonous and unsightly. , and the surface metal material is prone to oxidation due to contact with air.

Utility model content

The main purpose of the utility model is to provide a surface covering structure of the housing of an electronic device, which solves the problems in the prior art that the color of the housing is too monotonous and not aesthetically pleasing, and the metal surface material is oxidized due to contact with air.

The electronic device casing can also achieve the effect of having a highly dense metal texture through the following cladding structure. The cladding structure uses the electronic device casing as a metal substrate, and the surface of the substrate is provided with a laser engraving or etching treatment. Formed decorative area, and on the substrate is provided with a coating layer of one of electrodeposition coating, anodic treatment, painting treatment or electroplating treatment, wherein the substrate can be steel, iron, stainless steel, red Copper, brass, titanium alloy, carbon fiber, magnesium alloy, aluminum alloy, aluminum-magnesium alloy, tinplate and other metal materials or conductive materials.

The utility model has the advantage that the decorative area formed by laser engraving treatment or etching treatment and the coating layer of one of electrocoating treatment, anodic treatment, painting treatment or electroplating treatment can be formed to enhance the appearance aesthetics, And highly dense metal texture, and at the same time can obtain the desired color and pattern.

Detailed ways

As shown in accompanying drawing 1 and accompanying drawing 2, it is a perspective view and a cross-sectional view of a preferred embodiment of the present utility model, and it can be clearly seen from the figure that the utility model electronic device casing is a substrate 10, and the substrate 10 can be Steel, iron, stainless steel, red copper, brass, titanium alloy, carbon fiber, magnesium alloy, aluminum alloy, aluminum-magnesium alloy, tinplate and other metal materials or conductive materials, and a decoration is arranged on the surface of the substrate 10 Area 11, the decorative area 11 is formed by laser engraving treatment or etching treatment, and a cladding layer 12 in the form of electro-coating is provided on the substrate 10, thereby improving the appearance aesthetics, and It has a highly dense metallic texture, and at the same time can obtain the desired color and pattern.

Wherein, the coating layer 12 can also be coated by one of anodic treatment, painting treatment or electroplating treatment.

Composition design by above-mentioned structure, with regard to the usage situation of the present utility model, description is as follows, as shown in accompanying drawing 3 and accompanying drawing 4, it is the flow chart and flow diagram of the preferred embodiment of the present utility model, can clearly find out from the figure , the surface coating structure of the present utility model is carried out according to the following steps:

(a) performing laser engraving or etching on the surface of the substrate 10;

(b) a decorative area 11 is formed on the surface of the substrate 10;

(c) performing one of electrodeposition coating, anodizing, painting or electroplating on the surface of the substrate 10; and

(d) A cladding layer 12 is formed on the surface of the substrate 10 .

It can process the surface of the substrate 10 with laser engraving treatment or etching treatment to form a decorative area 11 on the surface of the substrate 10, and can further apply electrocoating treatment, anodic treatment, painting treatment or electroplating treatment, so that A cladding layer 12 is formed on the surface of the substrate 10, and then the substrate 10 is formed with a laser engraving treatment or an etching decoration area 11 for electrocoating, anodic treatment, painting treatment or electroplating treatment to form a cladding layer. Layer 12 is for the purpose of giving it a highly dense metallic texture.

The above-mentioned laser engraving process is also called laser engraving, that is, the cone-shaped beam emitted by the laser gun gathers a large amount of energy at the place where the beam is concentrated, which can melt the material, resulting in the effect of cutting or engraving. And electroplating is to make the powder pigment evenly adhere to the surface by energizing, but the surface will not fall off after being scraped off by sharp objects like powder, which can provide anti-corrosion and can be colored on the substrate 10 again.

The above-mentioned anodic treatment is an electrolytic process, the metal sheet that provides the plated metal acts like an anode, the electrolyte is usually an ion solution for plating the metal, and the plated object acts like a cathode. After the voltage is input between the anode and the cathode, the metal ions in the electrolyte are attracted to swim to the cathode, and then plated on it after reduction.
