The panel is made of metal, and the thermal expansion coefficient of the metal is one order of magnitude smaller than that of plastic, so that the size of the panel is hardly changed at high and low temperatures, and the structural strength of the metal panel is higher. Preferably, the metal material of the panel may be magnesium alloy, aluminum alloy or the like, and may be molded by a die casting process.
In summary, the assembly method of the invention uses the panel as the body, firstly adopts the mode of assembling the rear cover firstly, connects the rear cover with the panel by the modes of buckling, screwing and coating adhesive, can effectively prevent abnormal sound between the rear cover and the panel, then attaches the touch display component realizing the double-screen function to the front surface of the panel, and finally assembles the PCB circuit board component and the mounting bracket component on the back of the panel and respectively locks and attaches a plurality of screws.
Specifically, the technical effects are as follows:
(1) The back lid is assembled from the panel back, utilizes the reference column of back lid, spacing bone location, utilizes the buckle joint of back lid to connect on the panel, and a plurality of screws are attached from the positive lock of panel again, and at the front coating gluing agent of panel at last, in gluing agent fills panel constant head tank, spacing groove, screw groove, forms the bonding to reference column, spacing bone, the screw of back lid, can effectively take precautions against earthquakes and prevent abnormal sound.
(2) The panel adopts the metal material, and intensity is high, and PCB circuit board subassembly and back lid, installing support subassembly are independent and carry out the lock with the panel and attach the screw fixation, can effectively prevent abnormal sound bad.
The invention comprehensively utilizes the structural characteristics of the front and the back of the panel, matches the back cover to the back of the panel, realizes the fixation of the back cover from the front of the panel, the touch display module is attached and fixed to the front of the panel, the PCB circuit board component is locked and attached to the screw column in the surrounding bone of the back of the panel by the screw, the mounting bracket component is also locked and attached to the screw column outside the surrounding bone of the back of the panel by the screw, the back cover, the PCB circuit board assembly and the mounting bracket assembly are all fixed on the panel by adopting independent screws, the touch display module is fixed on the panel by using glue, the panel is used as a body part, and the components are all independently fixed with the panel body.
While the foregoing is directed to the preferred embodiments of the present invention, it will be appreciated by those skilled in the art that changes and modifications may be made without departing from the principles of the invention, such changes and modifications are also intended to be within the scope of the invention.
