Description

Portable electronic device

Technical Field

The present disclosure relates to electronic devices, and particularly to a portable electronic device.

Background

With the increasing computing performance of notebook computers, the heat generated by the internal electronic components (such as cpus, graphics processors, or other electronic components) during operation is also increasing. Once heat cannot be quickly discharged to the outside, the performance of the notebook computer is liable to slide down due to overheating. On the other hand, in a common notebook computer, most of hosts responsible for logic operation and data access are placed on a working plane (e.g., a desktop), and the bottom of the hosts is abutted against the working plane (e.g., the desktop), which is not only disadvantageous to heat dissipation, but also easily causes discomfort in operation for users.

Disclosure of Invention

The present invention is directed to a portable electronic device having excellent heat dissipation efficiency and operation comfort.

According to an embodiment of the present invention, a portable electronic device includes a first body, a second body, a hinge mechanism, a driving mechanism, and a door. The first body is provided with a bottom and a heat dissipation opening positioned at the bottom. The second machine body is connected with the first machine body through a hinge mechanism. The driving mechanism is connected with the hinge mechanism. The door cover is arranged corresponding to the heat dissipation opening and is pivoted to the bottom of the first machine body. The door cover is connected with the driving mechanism, and in a mode, the door cover closes the heat dissipation opening. In another mode, the driving mechanism drives the door cover to rotate relative to the first body so as 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 to improve the convenience of the user in 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. Based on the opening of the lifting mechanism, the first body is lifted relative to a working plane (such as a table top) and the angle of the first body is adjustable, so that the comfort level of a user when operating the first body is improved.

Detailed Description

Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.

Fig. 1 is a partially enlarged side view of a portable electronic device in a closed state according to an embodiment of the invention. Fig. 2 is a partially enlarged schematic view of the hinge mechanism, drive mechanism and door of fig. 1 from another perspective. Fig. 3 is a partially enlarged side view of the portable electronic device of fig. 1 in an unfolded state. Specifically, the first body 110 and the second body 120 are illustrated with dotted lines to clearly show the internal structural configuration.

Referring to fig. 1 to fig. 3, in the present embodiment, the portable electronic device 100 may be a notebook computer, which includes a first body 110, a second body 120, a hinge mechanism 130, a driving mechanism 140, and a door 150. The first body 110 is a host with logical operation and data access capabilities, and the second body 120 is a display. On the other hand, the second body 120 is connected to the first body 110 by a hinge mechanism 130 to rotate relative to the first body 110, and switches between a closed state shown in fig. 1 and an open state shown in fig. 3.

As shown in fig. 3, when the first body 110 operates, an internal heat source (e.g., a cpu, a graphic processor, or other electronic devices) generates heat, and the heat generated by the internal heat source must be rapidly exhausted to the outside, so as to prevent performance degradation of the first body 110.

As shown in fig. 1, the first body 110 has a heat dissipation opening 112 located at the bottom 111, and the door 150 closes the heat dissipation opening 112 to prevent external dust or other foreign objects from entering the interior of the first body 110 through the heat dissipation opening 112. As shown in fig. 3, the door 150 rotates relative to the first body 110 to open the heat dissipation opening 112. When the first body 110 operates, heat generated by an internal heat source can be rapidly discharged to the outside through the heat dissipation opening 112, so as to maintain the performance of the first body 110. While the heat dissipation opening 112 is opened, the door cover 150 supports the first body 110 such that the bottom 111 of the first body 110 is raised with respect to a work plane (e.g., a table top) to increase a space for the dissipation of hot air. In addition, the first body 110 is supported by the door 150 and is inclined relative to a working plane (e.g., a table top) to adjust an operation angle of the first body 110, thereby improving comfort of a user when operating the first body 110.

That is, the portable electronic device 100 integrates the heat dissipation mechanism and the lifting mechanism, so that the opening and closing of the heat dissipation mechanism and the lifting mechanism are substantially synchronous, thereby improving the convenience of the user in operation.

Referring to fig. 1 and 3, the first body 110 further has an air inlet 113 located at the bottom 111, wherein the air inlet 113 is used for allowing the external cold air to flow into the first body 110, and the heat dissipation opening 112 is used for discharging the internal hot air of the first body 110 to the outside. The heat dissipation opening 112 is adjacent to the air inlet opening 113, and in a state where the heat dissipation opening 112 is opened, the door cover 150 blocks an airflow path between the heat dissipation opening 112 and the air inlet opening 113 to prevent hot air from flowing back to the inside of the first body 110 through the air inlet opening 113.

Referring to fig. 1 to 3, in the process that the second body 120 rotates relative to the first body 110, the hinge mechanism 130 drives the driving mechanism 140, and the driving mechanism 140 drives the door 150 to rotate relative to the first body 110. That is, the rotation of the door cover 150 with respect to the first body 110 may be synchronized with the rotation of the second body 120 with respect to the first body 110. Further, in the process that the unfolding angle of the second body 120 relative to the first body 110 is gradually increased to a preset angle, the unfolding angle of the door 150 relative to the first body 110 is also gradually increased, and at the same time, the inclination angle of the first body 110 relative to a working plane (e.g., a table top) is also gradually increased.

The predetermined angle may be 120 degrees, but the invention is not limited thereto. Once the expansion angle of the second body 120 with respect to the first body 110 exceeds 120 degrees and is gradually increased, the expansion angle of the door 150 with respect to the first body 110 is gradually decreased, and at the same time, the inclination angle of the first body 110 with respect to a working plane (e.g., a table top) is also gradually decreased.

In this embodiment, the driving mechanism 140 is connected to the hinge mechanism 130, and the door 150 is connected to the driving mechanism 140. The door 150 is disposed corresponding to the heat dissipation opening 112 and pivotally connected to the bottom 111 of the first body 110. In detail, the hinge mechanism 130 has a first bracket 131, a second bracket 132 and a rotation shaft 133, wherein the first bracket 131 is fixed to the first body 110, and the second bracket 132 is fixed to the second body 120. The shaft 133 is fixed to the second bracket 132, wherein the shaft 133 rotatably penetrates through the first bracket 131, and the driving mechanism 140 is connected to the shaft 133.

When the second body 120 rotates relative to the first body 110, the second bracket 132 and the rotating shaft 133 move synchronously with the second body 120 and rotate relative to the first bracket 131. Meanwhile, the driving mechanism 140 is driven by the rotating shaft 133 to drive the door 150 to rotate relative to the first body 110, and the rotating direction R1 of the door 150 is the same as the rotating direction R2 of the rotating shaft 133.

Referring to fig. 1 to fig. 3, the driving mechanism 140 includes a first driving rod 141 and a second driving rod 142, wherein the first driving rod 141 is connected to the rotating shaft 133 and moves synchronously with the rotating shaft 133. The second driving rod 142 is pivotally connected to the first driving rod 141, and the door 150 is pivotally connected to the second driving rod 142. When the first driving rod 141 and the rotating shaft 133 rotate synchronously, the second driving rod 142 and the first driving rod 141 rotate relatively, and the second driving rod 142 pushes the door cover 150 to rotate relative to the first body 110 or pulls the door cover 150 to rotate relative to the first body 110.

Further, the first driving rod 141 has a fixed end 1411 and a first pivoting end 1412 opposite to the fixed end 1411, wherein the fixed end 1411 is fixed to the rotating shaft 133, and the first pivoting end 1412 is pivoted to the second driving rod 142. The second driving rod 142 has a second pivoting end 1421 and a third pivoting end 1422 opposite to the second pivoting end 1421, wherein the second pivoting end 1421 is pivoted to the first pivoting end 1412, and the third pivoting end 1422 is pivoted to the door cover 150.

On the other hand, the door 150 has a fourth pivoting end 151 and an active end 152, wherein the fourth pivoting end 151 is pivoted to the bottom 111 of the first body 110, and the third pivoting end 1422 is located between the fourth pivoting end 151 and the active end 152. When the door 150 is unfolded relative to the first body 110, the movable end 152 moves away from the bottom 111 or the heat dissipation opening 112 of the first body 110 to open the heat dissipation opening 112. Meanwhile, the movable end 152 of the door cover 150 abuts against a working plane (e.g., a table top) to support the first body 110. Conversely, the movable end 152 of the door cover 150 moves close to the bottom 111 or the heat dissipation opening 112 of the first body 110 to close the heat dissipation opening 112.

Specifically, the fourth pivot end 151 is located between the heat dissipation opening 112 and the air inlet opening 113, or the heat dissipation opening 112 and the air inlet opening 113 are located on two sides of the fourth pivot end 151.

In summary, the portable electronic device of the present invention integrates the heat dissipation mechanism and the lifting mechanism, so that the opening and closing of the heat dissipation mechanism and the lifting mechanism are substantially synchronous, thereby improving the convenience of the user in operation. Based on the opening of the heat dissipation mechanism, the door cover rotates relative to the first machine body to open the heat dissipation opening, so that heat generated by an internal heat source of the first machine body can be quickly discharged to the outside through the heat dissipation opening. Based on the opening of the lifting mechanism, the door cover supports the first machine body, so that the bottom of the first machine body is lifted relative to a working plane (such as a table top) to increase the space for hot air to escape. In addition, the first body is supported by the door cover and inclines relative to the working plane (such as a table top) so as to adjust the operation angle of the first body, and further improve the comfort degree of a user when the user operates the first body
