Flexible shell and preparation method thereof

Abstract

The present invention provides a flexible shell. The flexible shell comprises a rigid frame, an elastic fiber net and a flexible housing; the rigid frame comprises at least two separate rigid components; two ends of the elastic fiber net are fixedly connected with the two rigid components respectively, so that a bendable portion can be formed; the flexible housing covers at least the outer surfaceof the elastic fiber net; and when the elastic fiber net is in a state in which the elastic fiber net is not subjected to a bending force, a region of the flexible housing, which is corresponding tothe elastic fiber net, has wrinkles. According to the flexible shell of the invention, the elastic fiber net is arranged on the bent region of the flexible shell; by means of the pre-tensioning of theelastic fiber net, the bendable region of the flexible housing can form the wrinkles; when a machine body is bent, only the wrinkle portion of the flexible housing is tightened to be a smooth state,so that tensile modulus will not be increased, and therefore, a risk that the shell is cracked by tension can be lowered; with the wrinkles adopted, the shell almost has no creep when being stretched;the shell has a waterproof and dustproof function; and requirements of a flexible screen product, for the flexible shell, can be satisfied.

Description

technical field [0001] The invention relates to the technical field of housings of electronic products, in particular to a flexible housing and a preparation method thereof. Background technique [0002] Flexible electronic technology is an emerging electronic technology that manufactures organic / inorganic material electronic devices on flexible / ductile plastic or thin metal substrates. , national defense and other fields have broad application prospects, such as flexible electronic displays, organic light-emitting diodes (OLEDs), printed RFID, thin-film solar panels, and electronic skin patches (Skin Patches). [0003] When the flexible screen is face-to-face and bends inward, the schematic diagram of the stretching effect of the flexible shaft on the flexible shell is shown in figure 1 As shown, when the body is straightened, neither the flexible screen nor the shell is stretched; when the body is bent, the flexible screen is purely bent, while the flexible shell in the b...

AI Technical Summary

Problems solved by technology

[0009] 1) The shell is molded with polyurethane elastic material with high tensile strength. Although the polyurethane material has good comprehensive mechanical properties, its tensile modulus is relatively large, requiring a lot of force to stretch and deform, and it is easy to damage the precise flexible shaft. The user experience is not good;

[0010] 2) Silicone material with low tensile strength is used to form the housing. Although the tensile modulus of the silicone material can be made smaller, the mechanical properties of the silicone material are poor, it is easy to stretch and break, and the service life of the housing is very short

[0013] There are gaps between the metal bars, there are risks of dust, water, and hair pinching; if the gaps between the metal bars are too large and sharp, it may cut your fingers
