Portable Electronic Device

technical field

The present invention relates to an electronic device, in particular to a portable electronic device.

Background technique

With the continuous improvement of the computing performance of the notebook computer, the heat generated by the internal electronic components (such as a central processing unit, a graphics processing unit or other electronic components) during operation is also increasing. Once the heat cannot be quickly discharged to the outside world, the performance of the notebook computer is prone to decline due to overheating. On the other hand, in common notebook computers, the host responsible for logic operations and data access is mostly placed on the work plane (such as a desktop), and the bottom of the host is against the work plane (such as a desktop), which is not only bad for heat dissipation, It is also easy to cause the user to feel uncomfortable in operation.

The first body has a bottom and a heat dissipation opening at the bottom. The second body is connected to the first body through a hinge mechanism. The drive mechanism is connected to the hinge mechanism. The door cover is arranged corresponding to the heat dissipation opening, and is pivotally connected to the bottom of the first body. The door cover is connected to the drive mechanism, and in a mode, the door cover closes the heat dissipation opening. In another mode, the drive mechanism drives the door cover to rotate relative to the first body to open the heat dissipation opening and lift the first body.

Based on the above, the portable electronic device of the present invention integrates the heat dissipation mechanism and the lifting mechanism, so as to improve the convenience of the user's operation. Based on the opening of the heat dissipation mechanism, the heat generated by the internal heat source of the first body can be quickly discharged to the outside through the heat dissipation opening.

The first body 110 is a host capable of logic operation and data access, and the second body 120 is a display. On the other hand, the second body 120 is connected to the first body 110 through the hinge mechanism 130 to rotate relative to the first body 110 and switch between the closed state shown in FIG. 1 and the unfolded state shown in FIG. 3 .

As shown in FIG. 3, when the first body 110 operates, its internal heat source (such as a central processing unit, a graphics processor or other electronic components) generates heat, and the heat generated by the internal heat source must be quickly discharged to the outside to avoid the first The performance of a body 110 decreases.

As shown in FIG. 1 , the first body 110 has a heat dissipation opening 112 at the bottom 111 , and the door cover 150 closes the heat dissipation opening 112 to prevent external dust or other foreign objects from entering the first body 110 through the heat dissipation opening 112 . As shown in FIG. 3 , the door cover 150 is rotated relative to the first body 110 to open the heat dissipation opening 112 . When the first body 110 operates, the heat generated by the internal heat source can be quickly discharged to the outside through the heat dissipation opening 112 to maintain the performance of the first body 110 . When the heat dissipation opening 112 is opened, the door cover 150 supports the first body 110 so that the bottom 111 of the first body 110 is raised relative to the working plane (eg, a desktop) to increase the space for heat dissipation. In addition, the first body 110 is supported by the door cover 150 to be inclined relative to a work plane (eg, a desktop) to adjust the operating angle of the first body 110 , thereby improving the comfort of the user when operating the first body 110 .
