Shell structure for 3C (Computer, Communication and Consumer electronic) products

Abstract

The invention provides a shell structure for 3C products, which comprises a plastic forming component and a supporting board. The plastic forming component can be formed into different shapes in an injection way and comprises an outer surface and an inner surface opposite to the outer surface. The supporting board is integrated with the inner surface of the plastic forming component, wherein the bending elasticity resistance rate of the supporting board is larger than that of the plastic forming component, the supporting board is thinner than the plastic forming component, and the thickness of the supporting board is between 0.08 mm and 0.5 mm, therefore, the thickness and the cost of the shell are reduced, and the sufficient bending resistance strength is generated to resist pressure from the outer surface of the plastic forming component.

Description

technical field [0001] The invention relates to a shell structure of a product, in particular to a shell structure of a 3C product, which combines a thin support plate with a high bending elastic rate on the inner surface of a plastic molded part to generate sufficient bending strength and resist Pressure from an external force on the surface of a plastic molding. Background technique [0002] At present, most of the computer, electronic and communication (3C) product shell structures on the market are made of plastic injection molding or aluminum-magnesium alloy die-casting to protect the electronic components in the 3C products, but the two shell structures have their own advantages. pros and cons. [0003] Among them, the plastic injection molded case is relatively cheap in terms of material cost, but in order to make the case have enough strength to withstand the pressure from the outside of the 3C product, the thickness of the NB case is about 2mm or more. In this way...

AI Technical Summary

Problems solved by technology

[0003] Among them, the plastic injection molded case is relatively cheap in terms of material cost, but in order to make the case have enough strength to withstand the pressure from the outside of the 3C product, the thickness of the NB case is about 2mm or more. In this way, the overall volume and weight of the shell will be relatively increased

[0004] The aluminum-magnesium alloy die-casting shell, though the characteristics of the metal alloy itself, can have a thickness of about 0.5mm or more to have sufficient strength to withstand the external pressure from the 3C product, so that it meets the requirements of volume reduction and weight reduction; but Due to the difficulty in making metal alloys and the high unit price, the unit cost of the metal alloy shell is relatively higher than that of the plastic molded shell, and a higher material cost must be paid
