Description

TECHNICAL FIELD

[0001] The utility model relates to the field of electronic product accessories, specifically, relates to a full hard protective shell. BACKGROUND

[0002] The current intelligent terminal protective shell generally adopts soft silica gel or plastic, wherein the silica gel or plastic will appear discoloration after long time use, which affects the appearance; in addition, there is color difference between the intelligent terminal and the protective shell when installed on the intelligent terminal, which affects the appearance of the intelligent terminal.

[0003] Of course, some protective shells are made of metal, but the metal protective shell is generally only a metal frame, which is installed on the side shell of the intelligent terminal and cannot protect the whole intelligent terminal, and the metal frame has an opening structure, which is opened first when installed, and then fixed on the side of the intelligent terminal and closed to clamp the intelligent terminal, which is complex in operation and easy to damage.

[0004] If the metal or other hard material is made into a protective shell that wraps around the intelligent terminal to protect the frame and back of the intelligent terminal, such protective shell cannot be set with an opening structure due to the use of hard material, such as hard plastic or metal, which is difficult to install and disassemble and is easy to scratch the intelligent terminal.

[0005] On the other hand, the current intelligent terminal is different in key and interface position according to different models, and if the soft protective shell is made of silica gel or plastic, multiple different molds need to be made according to the intelligent terminal, and film injection or compression molding is needed, which causes one machine to have multiple molds and increases the production cost. TECHNICAL FIELD

[0006] The utility model aims at providing a full hard protective shell, which aims to solve the technical problems of the soft protective shell affecting the appearance, one machine having multiple molds causing cost increase, and / or the metal frame protective shell being unable to comprehensively protect the intelligent terminal, being difficult to disassemble and install.

[0007] The utility model provides a full hard protective shell, which is installed on an intelligent terminal, the intelligent terminal includes a frame and at least one back surface perpendicular to the frame, and the protective shell is fixed to the intelligent terminal to protect the frame and the back surface.

[0008] Specifically, the protective shell includes:

[0009] The soft inner layer includes a side wall and a first surface, the soft inner layer is fixed to the frame through the side wall, and the first surface covers the back surface;

[0010] The hard outer layer is fixed to the soft inner layer, and the soft inner layer is located between the intelligent terminal and the hard outer layer;

[0011] The hard outer layer and the soft inner layer are fixed to each other at the position of the side wall, or the hard outer layer and the soft inner layer are integrally formed through gluing or secondary injection molding; a plurality of through holes are arranged on the hard outer layer and the soft inner layer and opposite to each other, and the through holes are used for accommodating keys of the intelligent terminal or avoiding interfaces of the intelligent terminal.

[0012] The soft inner layer is fixed to the intelligent terminal, and then the hard outer layer made of metal is installed on the soft inner layer; the entire protective shell is made of hard material, especially metal material, and the soft inner layer and the hard outer layer wrap the frame and the back surface of the intelligent terminal; the entire protective shell is made of hard metal, and compared with a protective shell made of plastic or silica gel, the protective shell has a more beautiful and clean appearance, and a corresponding pattern can be arranged on the hard outer layer; in addition, the soft inner layer and the hard outer layer wrap the frame and the back surface of the intelligent terminal, and the protection effect is better.

[0013] The entire protective shell is made of hard structure, and when the hard structure is installed, the soft inner layer is first fixed on the intelligent terminal, and then the hard outer layer is fixed outside the soft inner layer, so that the technical problem that the hard structure of the protective shell is easily scratched during installation is overcome.

[0014] When the soft inner layer and the hard outer layer are integrally formed through secondary injection molding, the protective shell can be directly installed on the intelligent terminal, the possibility of scratching is effectively reduced when the soft inner layer is fixed on the intelligent terminal, the soft inner layer can be more conveniently fixed on the intelligent terminal, and the protective shell can protect the frame and the back surface of the intelligent terminal.

[0015] When the hard outer layer and the soft inner layer are fixed in the clamping mode, the hard outer layer and the soft inner layer can be separated, one of the hard outer layer and / or the soft inner layer can be replaced in time when the one is damaged or contaminated, and long-time use is realized.

[0016] Among them, when producing smart terminal protective cases for different models of the same model, a universal hard outer layer and a soft inner layer of corresponding sizes can be produced according to the same external length, width and thickness of the smart terminal; and then customized buttons and interface positions are different to adapt to different specific models of smart terminal protective cases. At this time, only mechanical processing, such as machine tool digging, CNC milling, etc., is needed to open through holes in the corresponding positions of the universal hard outer layer and the soft inner layer, so as to achieve adaptation to different models of smart terminals, thereby solving the technical problem of increased cost caused by multiple modes of one machine.

[0017] Among them, when the hard outer layer and the soft inner layer are made by secondary injection molding, the hard outer layer can be first made according to the universal length, width and height dimensions, and then the soft inner layer is formed by secondary injection molding inside the hard outer layer; making it a universal integrated structure, and then the universal integrated structure is machined according to the different button and interface positions corresponding to different models of smart terminals. Corresponding through holes are processed, and the protective case of the present invention can be produced conveniently and quickly. This method not only improves production efficiency, but also saves material costs and reduces product waste due to sales volume differences. BRIEF DESCRIPTION OF THE DRAWINGS
