Description

Portable electronic device

Technical Field

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

Generally, a notebook computer includes a first body responsible for logic operations and data access and a second body responsible for displaying images, and the second body is pivotally connected to the first body to rotate and expand relative to the first body or rotate and close relative to the first body. Further, the first body has a pivot side and a heat dissipation hole located on the pivot side, and most of the hot air inside the first body is discharged through the heat dissipation hole. In addition, the lower edge of the second body is pivoted to the pivoting side, and the second body only has a degree of freedom of movement relative to the first body in rotation. After the second body rotates and expands relative to the first body, the lower edge of the second body moves to the pivot side close to the first body and the heat dissipation hole located on the pivot side, and then the path of the hot air discharged outwards from the inside of the first body is blocked, so that the heat dissipation efficiency is poor.

Disclosure of Invention

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

The invention provides a portable electronic device, which comprises a first body, a second body and a hinge mechanism. The first body is provided with a pivoting side and a heat dissipation hole positioned on the pivoting side. The second body is rotatably and slidably connected to the first body by a hinge mechanism. The hinge mechanism comprises a rotating shaft, a first connecting rod, a second connecting rod and a third connecting rod. The rotating shaft is rotatably connected with the pivoting side of the first body. The first connecting rod is connected with the rotating shaft, and the second connecting rod is rotatably connected with the first connecting rod. The second connecting rod is rotatably connected with the second machine body. The third connecting rod is rotatably connected with the second machine body and can be slidably connected with the first machine body. When the second body rotates and unfolds relative to the first body through the hinge mechanism, the second body slides away from the pivoting side to enlarge the distance between the second body and the heat dissipation hole.

Based on the above, the second body slides relative to the first body while the second body rotates relative to the first body. Further, when the second body rotates and unfolds relative to the first body through the hinge mechanism, the second body slides relative to the first body and slides away from the pivoting side of the first body and the heat dissipation hole located on the pivoting side, so as 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 is not blocked by the lower edge of the second body, so that the hot air in the first body can be quickly discharged outwards through the heat dissipation hole, and the portable electronic device has excellent heat dissipation efficiency.

In order to make the aforementioned and other features and advantages of the invention more comprehensible, embodiments accompanied with figures are described in detail below.

Detailed Description

Fig. 1A is a partially enlarged schematic view of a portable electronic device in a closed state according to an embodiment of the invention. Fig. 1B is a partially enlarged schematic view of a portable electronic device in an unfolded state according to an embodiment of the invention. FIG. 1C is an enlarged partial side view of FIG. 1B. Referring to fig. 1A to 1C, in the present 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 has the capability of logic operation and data access, and the second body 120 has the capability 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 a degree of freedom of movement for the second body 120 to rotate and slide relative to the first body 110.

Further, while the second body 120 is rotated relative to the first body 110 by the hinge mechanism 130, the second body 120 may slide relative to the first body 110. The first body 110 has a hinge side 111 and a heat dissipation hole 112 located on the hinge side 111, and a portion of the hinge mechanism 130 is disposed on the first body 110 corresponding to the hinge side 111. The lower edge 121 of the second body 120 is connected to the first body 110 through a hinge mechanism 130, and another part of the hinge mechanism 130 is disposed on the second body 120 corresponding to the lower edge 121.

Referring to fig. 1A to 1C, the hinge mechanism 130 includes a rotation shaft 131, a first link 132, a second link 133 and a third link 135, wherein the rotation shaft 131 is rotatably connected to the pivot side 111 of the first body 110, and the first link 132 is connected to the rotation shaft 131. The shaft 131 and the first link 132 may be integrally formed, so that the shaft 131 and the first link 132 rotate synchronously. In addition, the first link 132 extends from the rotation shaft 131 to the second link 133, and the second link 133 is rotatably connected to the first link 132. That is, the rotation shaft 131 and the second link 133 are connected to both ends of the first link 132, respectively.

The second link 133 is rotatably connected to the second body 120, wherein 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, a main rotation stroke of the second body 120 is generated through the rotation shaft 131, and a 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 in synchronization with the second body 120, and includes a sliding stroke in the horizontal direction.

Further, the first body 110, the second body 120, the first link 132, the second link 133 and the third link 135 may form a five-link group, wherein the first body 110 may be regarded as a fixed member, and two joints (hereinafter, referred to as a first joint and a second joint) in the five-link group are located on the first body 110. The first contact is dropped on the rotating shaft 131, and the position of the first contact is kept still. In addition, the second contact is on the third link 135. And falls on an end of the third link 135 for sliding contact with the first body 110.

Referring to fig. 1A to 1C, the orthogonal projection of the third link 135 partially overlaps the rotating shaft 131, and the first link 132 crosses the third link 135. That is, the third link 135 extends through the upper side of the rotation shaft 131. Further, the first connecting rod 132 has a through slot 132a, wherein the through slot 132a is located between the rotating shaft 131 and the second connecting rod 133, and the through slot 132a linearly extends from one side of the first connecting rod 132 close to the rotating shaft 131 to the other side of the first connecting rod 132 close to the second connecting rod 133. The third link 135 extends from the second body 120 to the first body 110, wherein the third link 135 passes through the through slot 132a and is adapted to slide in the through slot 132 a.

Referring to fig. 1A to 1C, 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 slides away from the hinge side 111 of the first body 110 and the heat dissipation hole 112 located on the hinge side 111, so as to increase a 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 is not blocked by the lower edge 121 of the second body 120, so that the hot air inside the first body 110 can be quickly discharged through the heat dissipation hole 112, and the portable electronic device 100 has excellent heat dissipation efficiency.

Generally, the fan 140 is disposed in the first body 110 and is used for forcibly exhausting heat generated by a heat source (such as a central processing unit, a graphic processor or other electronic components) in the first body 110. Further, the cold air in the first body 110 forms hot air (i.e., hot air) after absorbing heat generated by the heat source, and the hot air is forcibly discharged through the heat dissipation hole 112 when the fan 140 is operated.

When the second body 120 rotates and unfolds relative to the first body 110 by the hinge mechanism 130, the second body 120 slides relative to the first body 110 and can generate displacement in the horizontal direction. Therefore, in the process that the second body 120 slides away from the pivot side 111 of the first body 110 and the heat dissipation hole 112 located on the pivot side 111, the second body 120 can move away from the pivot side 111 of the first body 110 along the horizontal direction to increase the distance between the lower edge 121 of the second body 120 and the heat dissipation hole 112, and provide sufficient heat dissipation space around the heat dissipation hole 112 to accelerate the dissipation of hot air to other places.

For example, as the angle of the second body 120 relative to the first body 110 is larger, the distance between the lower edge 121 of the second body 120 and the heat dissipation hole 112 is larger.

Referring to fig. 1B and fig. 1C, in the present embodiment, the first body 110 has a sliding slot 113 disposed corresponding to the rotating shaft 131, and one end of the third connecting rod 135 is slidably connected to the sliding slot 113. Further, the sliding slot 113 extends linearly toward the rotating shaft 131 in the first body 110 and ends in front of the rotating shaft 131. In addition, the extending direction 113a of the sliding chute 113 is perpendicular to the rotating shaft 131, and the extending direction 113a of the sliding chute 113 can be used for determining the horizontal sliding direction of the second body 120.

In summary, the second body slides relative to the first body while the second body rotates relative to the first body. Further, 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 pivoting side of the first body and the heat dissipation holes located on the pivoting side, so that the distance between the lower edge of the second body and the heat dissipation holes is increased. By increasing the distance between the lower edge of the second body and the heat dissipation hole, the heat dissipation hole is not blocked by the lower edge of the second body, so that the hot air in the first body can be quickly discharged outwards through the heat dissipation hole, and the portable electronic device has excellent heat dissipation efficiency.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
