Description

Technical Field

[0001] This invention relates to an electronic device, and more particularly to a portable electronic device. Background Technology

[0002] Common portable electronic devices include smartphones, tablets, and laptops. Because these portable electronic devices are easy for users to carry with them to send, receive, and process information in real time, they have become indispensable tools for modern people.

[0003] Taking laptops as an example, as the amount of data processing increases, laptops generate a significant amount of heat during operation. In terms of laptop configuration, the main heat sources are the central processing unit (CPU), graphics processing unit (GPU), or other electronic components, all housed within the main unit. Due to the limitations of the main unit's design, most of the heat generated is directed to the bottom or sides of the main unit for dissipation. However, the heat dissipation design on the bottom or sides of the main unit is easily obstructed by surrounding obstacles or suffers from insufficient heat dissipation area, resulting in poor cooling efficiency. Summary of the Invention

[0004] This invention relates to a portable electronic device with excellent heat dissipation efficiency.

[0005] According to an embodiment of the present invention, a portable electronic device includes a first body, a second body, a pivot, a heat source, a first flexible thermally conductive material, and a flip cover. The pivot connects to the second body, and the second body is pivotally connected to the first body via the pivot. The heat source is disposed within the first body. The first flexible thermally conductive material is thermally coupled to the heat source and extends from the heat source toward the pivot. The first flexible thermally conductive material passes through the pivot and extends into the interior of the second body to be thermally coupled to the second body. The flip cover is pivotally connected to the first body and is located on the movement path of the pivot.

[0006] Based on the above, in the portable electronic device of the present invention, the heat generated by the heat source can be conducted to the second body via the first flexible thermally conductive material, so that the heat can be dissipated from the second body to the outside. Because the second body can provide a larger heat dissipation area, the portable electronic device of the present invention has excellent heat dissipation efficiency. Attached Figure Description

[0010] 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 element references are used in the drawings and description to denote the same or similar parts.

[0011] Figure 1 This is a partial cross-sectional schematic diagram of a portable electronic device in a first state according to an embodiment of the present invention. Figure 2 This is a partial cross-sectional schematic diagram of a portable electronic device in a second state according to an embodiment of the present invention. Please refer to... Figure 1 and Figure 2 In this embodiment, the portable electronic device 100 may be a laptop computer, which includes a first body 110, a second body 120, a pivot 130, a heat source 140, a first flexible heat-conducting element 150, and a flip cover 160.

[0012] The first body 110 and the second body 120 are electrically connected, wherein the first body 110 can be used to perform logic operations, data access, and signal control, and the second body 120 can be a display. The second body 120 is pivotally connected to the first body 110 to open and close relative to the first body 110. Furthermore, a pivot member 130 connects the second body 120, and the second body 120 is pivotally connected to the first body 110 via the pivot member 130. At least a portion of the pivot member 130 is located within the first body 110 and has degrees of freedom of movement for sliding and rotation relative to the first body 110.

[0013] A heat source 140 is disposed within the first housing 110. The heat source 140 may be a central processing unit, a graphics processing unit, or other electronic components, and the heat generated by the heat source 140 can be conducted to the second housing 120 via the pivot 130. Specifically, a first flexible thermally conductive material 150 is thermally coupled to the heat source 140. The first flexible thermally conductive material 150 may be a wire or sheet made of copper, aluminum, graphite, or other highly thermally conductive materials, and is suitable for bending under stress without easily breaking.

[0014] One end of the first flexible thermally conductive material 150 is connected to the heat source 140 and extends from the heat source 140 toward the pivot member 130. Then, the first flexible thermally conductive material 150 passes through the pivot member 130 and extends into the second housing 120. The other end of the first flexible thermally conductive material 150 is connected to the second housing 120 for thermal coupling. Therefore, heat generated by the heat source 140 can be conducted to the second housing 120 via the first flexible thermally conductive material 150, allowing heat to dissipate from the second housing 120 to the outside. Because the second housing 120 provides a larger heat dissipation area, the portable electronic device 100 has excellent heat dissipation efficiency.

[0015] A hinged cover 160 is pivotally connected to the first body 110 and is located on the movement path of the pivot 130. In a first state, the second body 120 is closed onto the first body 110 and the hinged cover 160. In a second state, the second body 120 is unfolded relative to the first body 110, and the pivot 130 contacts and pushes the hinged cover 160, causing the hinged cover 160 to rise relative to the first body 110. At this time, the heat generated by the heat source 140 can dissipate to the outside through the gap between the hinged cover 160 and the first body 110, thus helping to improve the heat dissipation efficiency of the portable electronic device 100.

[0016] In this embodiment, the pivot member 130 has a channel 131, wherein the channel 131 has a first port 131a and a second port 131b opposite to the first port 131a. The first port 131a communicates with the interior of the first body 110, and the second port 131b communicates with the interior of the second body 120. A first flexible thermally conductive material 150 extends from the heat source 140 toward the first port 131a and passes through the channel 131 from the first port 131a. Then, it exits the channel 131 from the second port 131b to extend into the interior of the second body 120.

[0017] The first flexible thermally conductive material 150 includes a first section 151, a second section 152 connecting the first section 151, and a third section 153 connecting the second section 152. The first section 151 is disposed within the first body 110 and thermally coupled to the heat source 140. The second section 152 is disposed within the channel 131, and the third section 153 is disposed within the second body 120 and thermally coupled to the second body 120. Specifically, a portion of the first section 151 is located between the hinged cover 160 and the pivot member 130. In the second state, the pivot member 130 contacts the hinged cover 160 through the first section 151. That is, a portion of the first flexible thermally conductive material 150 is clamped between the hinged cover 160 and the pivot member 130. Therefore, heat conducted to the first flexible thermally conductive material 150 can also be conducted to the hinged cover 160 and dissipated to the outside from the hinged cover 160.

[0018] In this embodiment, the pivot member 130 includes a fixed end 132 and a driving end 133 relative to the fixed end 132, wherein the fixed end 132 is fixed to the second body 120, and the second port 131b is located at the fixed end 132. The driving end 133 is pivotally connected to the first body 110, wherein the first port 131a is located at the driving end 133, and the driving end 133 has degrees of freedom of sliding and rotating relative to the first body 110.

[0019] The flip cover 160 is located on the moving path of the drive end 133, and the drive end 133 is used to push the flip cover 160 and lift the flip cover 160, such as Figure 2As shown. In the second state, a portion of the first flexible thermally conductive material 150 is clamped between the drive end 133 and the flip cover 160. That is, the drive end 133 contacts the flip cover 160 through the first flexible thermally conductive material 150.

[0020] Please refer to Figure 1 and Figure 2 The portable electronic device 100 also includes a guide structure 170, which is disposed within the first body 110 and corresponds to the flip cover 160. Furthermore, a pivot 130 is slidably connected to the guide structure 170 and located between the flip cover 160 and the guide structure 170. When the second body 120 rotates relative to the first body 110, the pivot 130 is guided by the guide structure 170, causing the drive end 133 to move toward or away from the flip cover 160.

[0021] For example, the pivot 130 has a convex arc surface 134 facing the guide structure 170, and the guide structure 170 has a concave arc surface 171 facing the flap 160. The convex arc surface 134 at least partially contacts the concave arc surface 171, and the geometric profile of the concave arc surface 171 is complementary to the geometric profile of the convex arc surface 134 to improve the smoothness and stability of the pivot 130 sliding relative to the guide structure 170.

[0022] Figure 3 This is a partial cross-sectional schematic diagram of a portable electronic device in a second state according to another embodiment of the present invention. Please refer to... Figure 3 The design principle of the portable electronic device 100A in this embodiment is roughly the same as that of the portable electronic device 100 in the above embodiment. The difference is that the portable electronic device 100A in this embodiment also includes a second flexible thermal conductive material 180 thermally coupled to the heat source 140. The second flexible thermal conductive material 180 can be a wire or sheet made of copper, aluminum, graphite or other high thermal conductivity materials, and is suitable for bending under force without breaking easily.

[0023] Furthermore, a second flexible thermal conductive material 180 is disposed within the first body 110, wherein one end of the second flexible thermal conductive material 180 is connected to and thermally coupled to the heat source 140. The other end of the second flexible thermal conductive material 180 is connected to and thermally coupled to the hinged cover 160. Therefore, the heat generated by the heat source 140 can be conducted to the hinged cover 160 via the second flexible thermal conductive material 180, thereby providing another heat dissipation path and a larger heat dissipation area through the hinged cover 160.

[0024] In summary, in the portable electronic device of the present invention, heat generated by the heat source can be conducted to the second body via the first flexible thermal conductive material, allowing the heat to dissipate from the second body to the outside. Because the second body provides a larger heat dissipation area, the portable electronic device of the present invention has excellent heat dissipation efficiency. On the other hand, when the second body is unfolded relative to the first body, the flip cover rises relative to the first body, allowing heat generated by the heat source to dissipate to the outside through the gap between the flip cover and the first body. In some embodiments, heat generated by the heat source can be conducted to the flip cover via the second flexible thermal conductive material, providing another heat dissipation path and a larger heat dissipation area through the flip cover.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
