Description

Technical Field

[0001] The present invention belongs to the field of computer technology, and particularly relates to a tablet computer. Background Art

[0002] A tablet computer, also known as a portable computer (English: Tablet Personal Computer, abbreviated as TabletPC, Flat Pc), is a small and portable personal computer with a touch screen as the basic input device. The touch screen it has allows users to operate with a stylus or digital pen instead of a traditional keyboard or mouse. Users can achieve input through built-in handwriting recognition, on-screen soft keyboard, voice recognition, or a real keyboard (if equipped in the model). Many tablet computers on the market have unsatisfactory heat dissipation, so we designed a tablet computer with better heat dissipation effect. Summary of the Invention

The internal components include a main PCB board, which is communicatively controlled and connected to a secondary PCB board through a first FPC, and is electrically connected to a rechargeable battery board through a battery module and a power cord. The main PCB board is communicatively controlled and connected to an LCD socket behind the LCD TP cover plate through an LCD module and a second FPC. The main PCB board is snap-connected to a peripheral keyboard port fixed at the bottom of the frame and the bottom of the rear cover through a pogo pin module and a third FPC. The main PCB board is communicatively controlled and connected to an LCD TP socket fixed behind the LCD TP cover plate through an LCD TP module and a fourth FPC. The main PCB board is communicatively controlled and connected to both ends of a camera assembly located on one side of the main PCB board through a light sensor module and a fifth FPC, and a front camera module and a sixth FPC respectively;

[0005] A first heat dissipation component is fixedly connected to one side of the secondary PCB board, and a second heat dissipation component is provided with a notch on the main PCB board. The first heat dissipation component and the second heat dissipation component are respectively electrically connected to two FANs on the main PCB board through a first power line and a second power line;

[0006] Both ends of the rechargeable battery board are respectively fixedly connected to fixing blocks, and a heat dissipation copper tube is closely attached to the bracket. The heat dissipation copper tube conducts the heat of the CPU to the heat dissipation fins of the first heat dissipation component and the second heat dissipation component, and the heat is dissipated to the external space by means of a fan.

[0007] Preferably, a bracket for protecting the CPU is welded in the middle of the main PCB board, and an SSD module, a rear camera module, a POWER button, a USB module, a fingerprint control module, a communication module, a FAN connector and an RTC connector are arranged on the side. A DDR module and a control component for regulating the headphone volume are welded on the secondary PCB board.

[0008] Preferably, a frame is snap-fitted around the periphery surrounded by the main PCB board, the secondary PCB board, the first heat dissipation component, the second heat dissipation component, the battery and the fixing block. The frame is snap-fitted into the rear cover, and a plurality of second magnet groups are arranged in a groove where the bottom of the rear cover and the bottom of the frame overlap.

[0009] Preferably, the rear cover is designed with heat dissipation holes, air intake holes, a camera hole for snap-fitting the rear camera, and a plurality of strip-shaped grooves for snap-fitting a plurality of first magnet groups, third magnet groups and fixing strips.

[0010] Preferably, a fixing plate is fixedly connected behind the LCD TP front cover located inside the frame.

[0011] Preferably, the main PCB board, the secondary PCB board, the first heat dissipation component, the second heat dissipation component and the fixing plate are fixed to the rear cover by screws.

[0012] Preferably, a capacitive pen is magnetically attracted to the top of the rear cover.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. By arranging the second heat dissipation component on the main PCB board, the present invention can play a role in heat dissipation and temperature reduction for the rear camera module, SSD module and USB module welded around the second heat dissipation component; by arranging the first heat dissipation component on the secondary PCB board, the present invention can play a role in temperature reduction for the DDR module and the control component.

[0015] 2. By opening an opening on the main PCB board to arrange the second heat dissipation component, and the opening is directly opposite to the heat dissipation hole of the bottom cover, which is beneficial to the evacuation of hot air flow itself; the heat dissipation copper pipe conducts the high temperature of the core heat generating element CPU to the first and second heat dissipation components, and the bottom cover directly opposite to the first heat dissipation component is also designed with a heat dissipation hole, and the heat is conveniently convected with the outside through the fan and the air holes on the side edge of the bottom cover.

[0016] 3. The battery is in large-area contact with the rear cover, and the heat generated by the battery can be conducted and dissipated through the rear cover. The heat generated during the operation of the battery is also discharged to the outside of the tablet computer along with the hot air flow. The cold air flow enters through the air holes designed on the left and right sides of the tablet computer, effectively reducing the temperature inside the computer.

[0017] 4. The first, second and third magnet groups are beneficial to magnetically fixing the internal components to the bottom cover. Description of the Drawings:
