Portable electronic device

Abstract

The invention discloses a portable electronic device, comprising a host module, a screen module, an input module and a lifting lever; wherein the bottom side of the screen module is pivoted with the host module; the input module is adhered to the host module and is electrically connected with the host module, and the rear end thereof is pivoted with the host module; the lifting lever is arranged at the bottom of the screen module, when the screen module is rotatably lifted relative to the host module, the lifting lever can be driven to swing to push the front end of the input module to be hoisted, and the input module rotates by taking the rear end as axis and then is deviated from the host module. The structure is convenient for operation, and at the same time heat dissipation effect canbe greatly improved, so that the interior of the host module is maintained at low temperature, and energy consumption is reduced.

Description

technical field [0001] The invention relates to a portable electronic device, in particular to a portable electronic device which can improve heat dissipation performance. Background technique [0002] Notebook computers are very popular portable electronic devices nowadays. Due to their portability, easy storage and powerful functions, they have gradually become favored by business people and even ordinary gamers. A notebook computer generally includes a screen module and a host module that are pivotally connected to each other. During normal storage, the screen module covers the host module, on the one hand, covers the keyboard and switches on the host module, and prevents the computer from being turned on by accidental touch; Can protect the fragile LCD screen. [0003] When it is desired to use, the screen module is rotated relative to the host module to open a certain angle, so that the screen module is slightly upright, which is convenient for the user to see; at the ...

Problems solved by technology

However, with the trend of miniaturization of notebook computers, the problem of heat dissipation is even more important, because the internal components of notebook computers are fixed, including motherboards, central processing units, hard disks, memory, processing chips, etc., under high-frequency operation , will inevitably generate high heat, but because of the reduction in the overall size of the notebook computer, it is impossible to accommodate additional heat dissipation elements.

[0004] Furthermore, when operating a notebook computer, it is generally placed on a flat surface such as a desktop, and the desktop is mostly made of wood, plastic or other materials that are not easy to dissipate heat. On the other hand, there is a keyboard on the top of the host module, which is blocked by the keyboard, and the heat dissipation in this direction is not large. At the same time, if the hot air is forced to blow on the keyboard, the user will feel quite uncomfortable

[0005] Therefore, only the side of the overall space can be used for heat dissipation. However, as the thickness of the notebook computer becomes thinner and the thickness continues to decrease, the ability to dissipate heat will naturally decrease a lot. As a result, the overall temperature will increase, and the performance of the notebook computer will naturally decrease. use more energy to operate

At present, the more common method is to use a high-speed fan to maintain heat dissipation. However, once the fan speed increases, the power required will also increase. At the same time, the noise generated by the fan rotation will almost double.
