Description

Housing of electronic product and manufacturing method thereof

The invention relates to a housing for an electronic product and a method of manufacturing the same.

With the rapid development of information technology, portable electronic products such as mobile phones, PDAs (Personal Digital Assistants) and notebook computers are becoming more and more popular. The aesthetics and feel of these electronic products are getting more and more popular. Attention and attention. A conventional mobile phone casing, which is decorated with a paint varnish or the like, can enhance the aesthetic appearance of the casing, but the surface of the casing formed by spraying paint and the like is extremely easy to wear and the surface is coated with the paint. Peel off, which affects the appearance of the product.

In view of this, it is necessary to provide a housing for an electronic product that is aesthetically pleasing and less prone to wear.

There is also a need to provide a method of making the housing.

The invention provides a housing for an electronic product, comprising an opaque substrate, wherein a plurality of blind holes are formed in the base body, at least a portion of the blind holes are provided with a through hole at the bottom, and the at least part of the blind holes communicate with the through hole.

A manufacturing method of a casing for an electronic product, comprising the steps of: forming a base body; processing a plurality of blind holes on the base body; processing a through hole at a bottom portion of the blind hole, and the portion of the blind holes is in communication with the through hole.

Compared with the prior art, the housing made by the manufacturing method of the present invention has a through hole at the bottom of a part of the blind hole of the surface of the base body. When the mobile phone is operated or has an incoming call, the light emitted inside is emitted by the mobile phone. The through hole is ejected to form a mobile phone having a specific bright light pattern, so that the electronic product to which the casing is applied is more beautiful. Moreover, the surface of the casing is not sprayed with paint, so that the paint skin does not wear off.

The present invention provides an electronic product housing, which is described by way of example for application to a mobile phone.

Referring to FIG. 1 and FIG. 2 together, the housing 10 of the first preferred embodiment of the present invention has a flat shape and includes a base 102. The base 102 is opaque and made of a metal material. The base 102 includes a first A surface 1022. A plurality of blind holes 1024 are formed on the first surface 1022. The blind holes 1024 are a circular blind hole having a diameter of 0.3 mm and a depth of 0.1 mm to 0.2 mm. A through hole 1026 is formed in the bottom of the partial blind hole 1024, and the plurality of through holes 1026 are circular through holes having a diameter of 0.2 mm. The arrangement of the plurality of through holes 1026 forms a specific pattern. The plurality of through holes 1026 are filled with a transparent filler 104 to prevent dust or moisture from entering the casing 10. Since the plurality of through holes 1026 are small in diameter and open at the bottom of the plurality of blind holes 1024, it is difficult to find that the plurality of through holes 1026 are formed in the base 102 when viewed from the first surface 1022 of the base 102. When the mobile phone is operated or has an incoming call, light is emitted from the inside, and the light is emitted from the plurality of through holes 1026 through the transparent filler 104, thereby forming a mobile phone having a specific bright light pattern.

Referring to FIG. 3, the housing 20 of the second preferred embodiment of the present invention includes a base. The body 202 includes a body 2022 and two side walls 2027, 2028 extending perpendicularly from the body 2022, respectively. The main body 2022 and the two side walls 2027, 2028 together form an outer surface 2029, and a plurality of blind holes 2024 are formed on the outer surface 2029. The blind hole 2024 is a circular blind hole, and a plurality of circular through holes 2026 are defined in the bottom of the partial blind hole 2024 corresponding to the main body 2022 of the base body 202 and the two side walls 2027, 2028, and the plurality of through holes 2026 are arranged. Form a specific pattern. A transparent filler 204 is formed in the plurality of through holes 2026 to prevent dust or moisture from entering the housing 20.

Taking the housing of the first preferred embodiment as an example, the manufacturing method includes the following steps: First, the metal plate is stamped by a punching machine to form a base 102 having a thickness of about 0.5 mm, in this embodiment. The base 102 is a rectangular housing.

Then, a plurality of blind vias 1024 are first formed on the first surface 1022 of the substrate 102 by using a laser engraving technique. The plurality of blind vias 1024 are sequentially arranged on the first surface 1022 of the substrate 102. The diameter of the plurality of blind vias 1024 is 0.3. Mm, the depth is between 0.1mm-0.2mm. A plurality of through holes 1026 having a diameter of 0.2 mm are formed by the laser engraving technique at the bottom of the partial blind holes 1024, and the plurality of through holes 1026 form a specific pattern shape.

The substrate 102 is then polished, after the lubricant is applied to the polishing cloth wheel, and then the first surface 1022 of the substrate 102 is rubbed with a polishing cloth wheel that rotates at a high speed to remove scratch marks on the surface thereof. ,improve The flatness of the first surface 1022 and the brightness of the light.

The substrate 102 is then cleaned to remove stains such as lubricant on the first surface 1022 of the substrate 102.

Finally, the plurality of through holes 1026 are sealed, and the transparent filler 104 is filled into the plurality of through holes 1026.

It can be understood that, in the manufacturing method of the housing of the electronic product, a plurality of through holes may be processed on the substrate, and a plurality of blind holes are formed around the through holes, so that the through holes are formed in the plurality of blind holes. .

It can be understood that the shape of the plurality of blind holes and the plurality of through holes is not limited to a circular shape, and may be other shapes such as a rectangle, a diamond shape, or the like.

It can be understood that the transparent filler may be a transparent substance such as a transparent resin to emit light from the inside of the casing through the through hole.

It can be understood that the transparent filler can also be filled into the blind hole with the through hole at the bottom.

It can be understood that the diameter of the circular plurality of blind holes and the plurality of through holes can be adjusted according to the size of the product.

It can be understood that the casing processed by the method can be applied not only to mobile phones but also to electronic products such as game machines and notebook computers.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above embodiments, and those skilled in the art will be able to make equivalent modifications or variations in accordance with the spirit of the present invention.
