Mobile terminal devices have been widely used, such as mobile phones (ie mobile phones), which have become an indispensable communication tool in people's work and life. Considering factors such as being beautiful and practical, and easy to carry, mobile terminals have emerged in various forms of ultra-thin products.

At present, ultra-thin mobile terminal devices have the following two implementations:

1. As shown in FIG. 1 , taking the mobile phone as an example, the main board 101 of the mobile phone is a whole board, and the display screen 102 and the receiver 106 are placed on the upper half of the main board 101, and the lower part of the front side of the main board 101 is the keyboard 103. In the area, the upper half of the back of the main board 101 is the area where the radio frequency and the antenna 104 are placed, and the lower part of the back side of the main board 101 is the area where the battery 105 is placed. Generally speaking, the reason for affecting the thickness of the mobile phone is that the components on the motherboard 101 (such as the RF and the antenna 104) are too large and the battery 105 is too thick. Therefore, this layout largely limits the thickness of the whole machine, such as If you want to design an ultra-thin structure, you can only choose a thin battery 105 and a small RF device and an antenna 104 device. The thinner battery has a relatively small capacity, and the user needs to frequently charge the mobile phone to meet the usage requirements. Small devices are often several times more expensive than ordinary devices of the same function and cost more.

2. As shown in FIG. 2, taking the mobile phone as an example, the main board of the mobile phone is divided into an independent baseband radio frequency main board 207 and a keyboard board 208, so that the baseband radio frequency main board 207 and the keyboard board 208 can be arranged by borrowing, and the keyboard board 208 and the display screen are arranged. 202 is arranged on the same plane, a battery 205 is arranged under the keyboard board 208, and a baseband radio frequency main board 207 is arranged under the display screen 202. Although such a layout does not need to use a thin battery 105, it is still necessary to select a small-sized RF device and an antenna device. , the cost is higher; and the structure is relatively complicated. Summary of the invention

The present invention provides a mobile terminal device, whereby the ultra-thin structure of the mobile terminal device can be realized at a low cost, and at the same time, the structure is simple.

The present invention provides a mobile terminal device including a main board, a keyboard board, a display unit and a battery which are electrically connected to each other inside the housing, and the display unit and the keyboard board are disposed on an operation surface of the mobile terminal device. The main board and the battery are disposed on the back of the mobile terminal device, wherein the battery is stacked on the back of the display unit; and the main board is disposed on the back of the keyboard board.

It can be seen from the above technical solution that since the mobile terminal device stacks the battery on the back side of the display component; the motherboard is disposed on the back of the keyboard board, thereby effectively utilizing the existing space of the mobile terminal device. The ultra-thin structure of the mobile terminal device is realized at a low cost, and at the same time, the structure is simple. DRAWINGS
