Aluminum sheet encapsulating protective jacket and production process thereof

Abstract

The invention discloses an aluminum sheet encapsulating protective jacket and a production process thereof. The protective jacket comprises a bottom plate adaptive to a bottom surface of a cellphone in shape and size, and an outer aluminum frame adaptive to an outer frame of the cellphone in shape and size; the inner wall of the outer aluminum frame is subjected to injection molding of an adhesive to form an inner soft adhesive frame wrapping the inner wall of the outer aluminum frame; the position, close to the edge, of the bottom end of the bottom plate downwards extends to form a snap ring; the inner soft adhesive frame is inwards sunk to form a circle of clamp slot adaptive to the snap ring in shape and size; after the clamp ring is clamped into the clamp slot; the bottom plate is fixedly connected into the inner soft adhesive frame and defines a containing cavity adaptive to the cellphone in shape and size together with the outer aluminum frame. The inner soft adhesive frame fully wraps the inner wall of the outer aluminum frame, and soft adhesive full wrapping is adopted to isolate the outer surface of the cellphone from the outer aluminum frame, so that a phenomenon that the surface of the cellphone is of scraped is effectively avoided; moreover, through the full wrapping, a good buffering effect is realized, and the cellphone is directly fixed in the inner soft adhesive frame, thus ensuring stable structural strength and avoiding a phenomenon that the cellphone is separated from the protective jacket after falling down.

Description

technical field [0001] The invention relates to the technical field of production of mobile phone protective covers, in particular to an aluminum sheet rubber-coated protective cover and a production process thereof. Background technique [0002] Existing mobile phone cases are generally formed by assembling an aluminum alloy frame and a bottom cover. This kind of mobile phone protective case has the following defects no matter in the production process or structure: [0003] 1) If the frame of the existing mobile phone case is wrapped with aluminum alloy, although it has a certain structural stability, the aluminum alloy will shield the mobile phone signal, which will affect the mobile phone signal, such as affecting the mobile phone receiving signal, affecting the GPS positioning signal, etc.; eventually causing The phone doesn't work properly. [0004] 2) The existing mobile phone protective case is only provided with soft glue at the bend of the inner wall of the protec...

AI Technical Summary

Problems solved by technology

[0003] 1) If the frame of the existing mobile phone case is wrapped with aluminum alloy, although it has a certain structural stability, the aluminum alloy will shield the mobile phone signal, which will affect the mobile phone signal, such as affecting the mobile phone receiving signal, affecting the GPS positioning signal, etc.; eventually causing The phone is not working properly

[0004] 2) The existing mobile phone protective case is only provided with soft glue at the bend of the inner wall of the protective case, so the surface of the mobile phone is prone to scratches; and the existing mobile phone protective case is not high in strength and unstable in structure; if the mobile phone After falling, the bottom cover of the protective case, the frame and the mobile phone will be separated; not only the mobile phone cannot be effectively protected, but the mobile phone protective case will be damaged once it falls off.

[0005] 3) The existing aluminum alloy frame and the bottom cover are mainly fastened by buckles. Since the bottom cover and the aluminum alloy frame are made of hard materials, the buckle will wear out after long-term use; After wear and tear, the frame and the bottom cover cannot be tightly bonded, and it is more likely that the protective cover of the mobile phone will be detached and the mobile phone will fall off

[0006] 4) The outer buttons of the mobile phone protective cover and the mobile phone buttons on the existing market are all pasted on the frame of the mobile phone with adhesive tape. After long-term use or exposure to water, the viscosity of the adhesive tape will decrease, thus reducing the The sensitivity of the cooperation between the external buttons and the buttons of the mobile phone causes the inaccurate cooperation between the two, which ultimately shortens the service life of the mobile phone case

[0007] 5) In the production process of the existing mobile phone protective cover, the soft glue can only be fixed at the corners of the protective cover, and this kind of soft glue is not strong. After a long time of use, the soft glue and the frame will fall off

[0008] Based on the above description, the above-mentioned mobile phone protective case cannot meet the use of the issued 6&plus, so there is an urgent need to develop a mobile phone protective case suitable for 6&plus
