Description
Technical Field
The invention relates to the technical field of display devices, in particular to a mobile display device.
Background
With the appearance of the full-face screen and the special-shaped screen of the mobile phone, the length and the width of the whole mobile phone are gradually reduced, but the size of the display screen of the mobile phone is gradually increased, and the screen occupation ratio is increased. Under the same use condition, the consumption of the mobile phone to the electric quantity is increased. However, as the length and width of the whole battery are reduced, the length and width of the battery are reduced, but the capacity of the battery required by the product can be kept unchanged or increased, and under the existing battery system, the difficulty in increasing the energy density of the battery is greater in consideration of the safety of the battery.
In the prior art, a cross-sectional structure of a mobile phone in a thickness direction is generally shown in fig. 1, and includes a touch panel 01, a display screen 02, a middle frame 03, a battery 04, and a battery cover 05. The middle frame 03 is generally made of magnesium alloy, aluminum alloy or stainless steel. The thickness of the magnesium alloy and the aluminum alloy is generally 0.6mm, and the thickness of the stainless steel is 0.4mm under the same strength. Under the same strength condition, the thickness of the battery can be increased by 0.2mm by using stainless steel rather than aluminum and magnesium alloy, and the capacity of the battery can be increased by about 160mAh under the same type and the same length and width dimensions. However, the stainless steel has high strength and is difficult to mill grooves, so that the whole middle frame 03 is made of stainless steel, and the manufacturing process is difficult. Therefore, in order to reduce the thickness, in the prior art, only the battery compartment in the middle frame 03 is made of stainless steel, and the frame in the middle frame 03 is still made of aluminum and magnesium alloy, so that the plasticity of the frame is facilitated, the thickness of the battery compartment can be reduced, the thickness of the battery is increased, and the strength of the whole middle frame 03 can be ensured. However, in such a structure, the connection between the battery compartment and the frame becomes difficult. Because aluminum and magnesium alloy can not be directly welded with a stainless steel plate, the conventional combination scheme mainly comprises the following two schemes: firstly, stainless steel and aluminum alloy are directly injected together, but due to different shrinkage rates of the stainless steel and the aluminum alloy, the aluminum alloy extrudes the stainless steel plate in four directions, so that the stainless steel plate is easy to deform and cannot be used; secondly, the double-sided adhesive tape is adopted for bonding, so that the connection reliability cannot be met, and the double-sided adhesive tape is easy to separate when mechanical tests such as falling are carried out. Therefore, the conventional combination scheme in the prior art cannot meet the requirement of stable connection of the frame and the stainless steel battery compartment.
