Further, as for the material composition of the plurality of sheet layers 100 of the present application, it may be specifically an all-plastic material layer, that is, each sheet layer 100 is a plastic layer. It may also be a full glass layer, i.e., each ply 100 is a glass layer. The all-plastic material layer structure has the advantage of light overall quality, but the structural strength is poor. The whole glass layer structure has good aesthetic property, but has large overall mass and the condition of poor structural strength and frangibility. For this reason, in the present application, in terms of the material composition of the plurality of sheet layers 100, a combination of a glass layer, a plastic layer, and a metal layer is preferable, that is, a part of the plurality of sheet layers 100 is the glass layer, a part of the plurality of sheet layers 100 is the material layer, and a part of the plurality of sheet layers 100 is the metal layer, so that the overall quality can be balanced, and the structural strength can be enhanced, and the glass layer can be used to improve the beauty.

In addition, one of the two adjacent cover sheet layers 100 between the cover sheet layer 1 and the bottom sheet layer 3 is a metal layer 100, and the other cover sheet layer 100 is a plastic layer, i.e. the cover sheet layer is formed by alternating metal layers and plastic layers in the middle layer 2. Through interlude metal level and plastic layer in intermediate level 2, the holistic structural strength can further be improved to the metal level, and the passing of radio frequency can be guaranteed to the plastic layer. The material layer is formed, so that the overall quality can be well balanced, certain attractiveness is achieved, and the structural strength is good.

Further, in the case of the material layer composition, that is, when the cover plate layer 1 is a glass layer, the plate layer 100 adjacent to the cover plate layer 1 may be a material layer made of a light diffusion plate material. The light striking the glass layer can be homogenized by the light-diffusing plate to reduce the influence of light reflection on face recognition.

Further, use apron layer 1 as the glass layer for the example, in order to play the protection to apron layer 1, four angular segments of apron layer 1 can be equipped with opening 13 respectively, again through the angle bead 4 of first screw 51 installation metal at each opening 13, wherein the corner position of angle bead 4 can be filleted corner respectively and handle, play certain anti guard action that falls to four corners of apron layer 1, the centre gripping fixed action through angle bead 4 simultaneously, can also play certain installation reinforcing action to apron layer 1.

Further, as for the connection between the respective board layers 100, a double-sided adhesive layer 200 may be disposed between any two adjacent board layers 100, and the two adjacent board layers are bonded by the double-sided adhesive layer. To further improve the stability of the connection, second screws 52 may be added to fasten the respective plate layers 100 of the middle layer 2, and third screws 53 may be added to fasten the last plate layer 100 to the plate layer 100 of the middle layer 2. The space between the first sheet layer 100 and the sheet layer 100 of the intermediate layer 2 may be reinforced by the corner protector sheet 4.

Further, to further strengthen the overall structure, a plurality of metal reinforcing bars 7 may also be included. A plurality of reinforcing bars 7 are installed on the back of the floor layer 3 along the length direction of the floor layer 3, and are arranged at intervals along the width direction of the floor layer 3, and the reinforcing bars 7 can be fastened by fourth screws 54. Not only can play the effect of strengthening overall structure intensity, also can strengthen certain radiating effect.

Further, the back surface of the floor layer 3 is mounted with the outlet terminals 6 connected to the circuit board 81. The structure of the outlet terminal 6 can also be designed with reference to the housing structure, that is, the housing structure of the outlet terminal 6 is formed by stacking a plurality of metal sheets 61 through fifth screws 55, and a mounting cavity for mounting the terminal device 62 is formed between the plurality of metal sheets 61. Thereby being convenient for processing and reducing the waste of processing resources.
