Description

Portable electronic device

The present invention relates to an electronic device, and more particularly to a portable electronic device.

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 processor 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 likely to decline due to overheating.

Generally speaking, a notebook computer includes a first body responsible for logic operations and data access, and a second body responsible for displaying images. The second body is pivotally connected to the first body to rotate and expand or be opposite to the first body. The first body rotates and closes. Furthermore, the first body has a pivotal side and a heat dissipation hole on the pivotal side, and most of the hot air inside the first body is discharged outward through the heat dissipation hole. In addition, the lower edge of the second body is pivotally connected to the pivoting side, and the second body only has a degree of freedom of movement relative to the rotation of the first body. After the second body rotates and unfolds relative to the first body, the lower edge of the second body will move closer to the pivot side of the first body and the heat dissipation holes on the pivot side, thereby blocking the direction of hot air inside the first body The path of external discharge, so the heat dissipation efficiency is not good.

The present invention provides a portable electronic device with excellent heat dissipation efficiency.

The present invention provides a portable electronic device, which includes a first body, a second body, and a hinge mechanism. The first body has a pivotal side and a heat dissipation hole on the pivotal side. The second body is rotatably and slidably connected to the first body through a hinge mechanism. The hinge mechanism includes a rotating shaft, a first link, a second link, and a third link. The rotating shaft is rotatably connected to the pivot side of the first body. The first connecting rod is connected to the rotating shaft, and the second connecting rod is rotatably connected to the first connecting rod. The second link is rotatably connected to the second body. The third link is rotatably connected to the second body, and the third link is slidably connected to the first body. When the second body rotates and expands relative to the first body through the hinge mechanism, the second body slides away from the pivoting side to increase the distance between the second body and the heat dissipation hole.

Based on the above, while the second body rotates relative to the first body, the second body slides relative to the first body. Furthermore, when the second body rotates and expands relative to the first body through the hinge mechanism, the second body slides relative to the first body and slides away from the pivot side of the first body and the heat dissipation hole on the pivot side, In order to increase the distance between the lower edge of the second body and the heat dissipation hole. By increasing the distance between the lower edge of the second body and the heat dissipation hole, the heat dissipation hole will not be blocked by the lower edge of the second body, so that the heat inside the first body can be quickly discharged through the heat dissipation hole. The portable electronic device of the present invention has excellent heat dissipation efficiency.

In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

FIG. 1A is a partially enlarged schematic diagram of a portable electronic device in a closed state according to an embodiment of the present invention. FIG. 1B is a partially enlarged schematic diagram of a portable electronic device in an unfolded state according to an embodiment of the present invention. Fig. 1C is a partial enlarged schematic side view of Fig. 1B. 1A to 1C, in this embodiment, the portable electronic device 100 may be a notebook computer, and includes a first body 110, a second body 120, and a hinge mechanism 130. The first body 110 is capable of logical operations and data access, and the second body 120 is capable of displaying images. The second body 120 is connected to the first body 110 through a hinge mechanism 130, and the hinge mechanism 130 provides the freedom of movement of the second body 120 to rotate and slide relative to the first body 110.

Furthermore, while the second body 120 rotates relative to the first body 110 through the hinge mechanism 130, the second body 120 can slide relative to the first body 110. The first body 110 has a pivoting side 111 and a heat dissipation hole 112 on the pivoting side 111, and a part of the hinge mechanism 130 is provided on the first body 110 corresponding to the pivoting side 111. The lower edge 121 of the second body 120 is connected to the first body 110 through the hinge mechanism 130, and another part of the hinge mechanism 130 is disposed on the second body 120 corresponding to the lower edge 121.

1A to 1C, the hinge mechanism 130 includes a rotating shaft 131, a first link 132, a second link 133, and a third link 135. The rotating shaft 131 is rotatably connected to the pivot side 111 of the first body 110. And the first connecting rod 132 is connected to the rotating shaft 131. The rotating shaft 131 and the first connecting rod 132 may be an integral structure, so the rotating shaft 131 and the first connecting rod 132 rotate synchronously. In addition, the first connecting rod 132 extends from the rotating shaft 131 to the second connecting rod 133, and the second connecting rod 133 is rotatably connected to the first connecting rod 132. In other words, the rotating shaft 131 and the second connecting rod 133 are respectively connected to two ends of the first connecting rod 132.

The second link 133 is rotatably connected to the second body 120, the third link 135 is rotatably connected to the second body 120, and the third link 135 is slidably connected to the first body 110. That is, the first link 132 and the second body 120 are respectively connected to two ends of the second link 133, and the second link 133 and the third link 135 are respectively connected to two different points of the second body 120. When the second body 120 rotates and slides relative to the first body 110 through the hinge mechanism 130, the main rotation stroke of the second body 120 is generated through the rotating shaft 131, and the main sliding stroke of the second body 120 is generated through the third link 135. Therefore, the third link 135 slides relative to the first body 110 synchronously with the second body 120, and includes a sliding stroke in the horizontal direction.

Furthermore, the first body 110, the second body 120, the first link 132, the second link 133, and the third link 135 can form a five-link group, where the first body 110 can be regarded as a fixed part, and the five The two contacts in the connecting rod group (hereinafter referred to as the first contact and the second contact) are located on the first body 110. The first contact point falls on the rotating shaft 131, and the position of the first contact point remains stationary. In addition, the second contact point falls on the third link 135. And it falls on the end of the third connecting rod 135 for slidably connecting with the first body 110.

Please refer to FIGS. 1A to 1C, the orthographic projection of the third connecting rod 135 partially overlaps the rotating shaft 131, and the first connecting rod 132 is staggered with the third connecting rod 135. In other words, the third link 135 extends above the rotating shaft 131. Furthermore, the first connecting rod 132 has a through groove 132a, wherein the through groove 132a is located between the rotating shaft 131 and the second connecting rod 133, and the through groove 132a linearly extends from the side of the first connecting rod 132 close to the rotating shaft 131 The other side of the first link 132 close to the second link 133. The third link 135 extends from the second body 120 to the first body 110, wherein the third link 135 passes through the slot 132a and is adapted to slide in the slot 132a.

1A to 1C, when the second body 120 rotates and expands relative to the first body 110 through the hinge mechanism 130, the second body 120 slides relative to the first body 110 and slides away from the pivot of the first body 110 The side 111 and the heat dissipation hole 112 on the pivotal side 111 are used to increase the distance between the lower edge 121 of the second body 120 and the heat dissipation hole 112. By increasing the distance between the lower edge 121 of the second body 120 and the heat dissipation hole 112, the heat dissipation hole 112 will not be blocked by the lower edge 121 of the second body 120, so that the heat inside the first body 110 can quickly pass through The heat dissipation holes 112 are discharged outward, so the portable electronic device 100 has excellent heat dissipation efficiency.

Generally speaking, the fan 140 is disposed in the first body 110 and is used to forcibly exhaust heat generated by a heat source (such as a central processing unit, a graphics processor, or other electronic components) in the first body 110. Furthermore, the cold air in the first body 110 will form hot air (ie, hot air) after absorbing the heat generated by the heat source. When the fan 140 is running, the hot air can be forcibly discharged through the heat dissipation hole 112.

When the second body 120 rotates and unfolds relative to the first body 110 through the hinge mechanism 130, the second body 120 slides relative to the first body 110 and can be displaced in a horizontal direction. Therefore, when the second body 120 slides away from the pivoting side 111 of the first body 110 and the heat dissipation hole 112 on the pivoting side 111, the second body 120 can move in the horizontal direction away from the pivoting of the first body 110 The side 111 increases the distance between the lower edge 121 of the second body 120 and the heat dissipation hole 112, and provides sufficient heat dissipation space around the heat dissipation hole 112 to accelerate the escape of hot air to other places.

For example, as the expansion angle of the second body 120 with respect to the first body 110 increases, the distance between the lower edge 121 of the second body 120 and the heat dissipation hole 112 becomes larger.

1B and 1C, in this embodiment, the first body 110 has a sliding groove 113 corresponding to the rotating shaft 131, and one end of the third link 135 is slidably connected to the sliding groove 113. Furthermore, the sliding groove 113 linearly extends toward the rotating shaft 131 in the first body 110 and stops in front of the rotating shaft 131. In addition, the extending direction 113a of the sliding groove 113 is perpendicular to the rotating shaft 131, and the extending direction 113a of the sliding groove 113 can be used to determine the horizontal sliding direction of the second body 120.

In summary, while the second body rotates relative to the first body, the second body slides relative to the first body. Furthermore, when the second body rotates and expands relative to the first body through the hinge mechanism, the second body slides relative to the first body and slides away from the pivot side of the first body and the heat dissipation hole on the pivot side, In order to increase the distance between the lower edge of the second body and the heat dissipation hole. By increasing the distance between the lower edge of the second body and the heat dissipation hole, the heat dissipation hole will not be blocked by the lower edge of the second body, so that the heat inside the first body can be quickly discharged through the heat dissipation hole. The portable electronic device of the present invention has excellent heat dissipation efficiency.
