PORTABLE ELECTRONIC APPARATUS

The novel creation is related to a portable electronic device.

In recent years, with the development of the technology industry, portable electronic devices such as notebook computers, personal digital assistants, and smart phones have frequently appeared in daily life. Some of the electronic components carried in these portable electronic devices usually generate thermal energy during operation, which affects the operational efficiency of the electronic device. Therefore, the interior of the portable electronic device is usually provided with a heat dissipating component, such as a heat dissipating fan, a heat dissipating material or a heat dissipating tube, to assist in dissipating heat generated by the electronic component to the outside of the portable electronic device.

Taking a notebook computer as an example, when a notebook computer on the market is equipped with a portable electronic device, since the heating element of the notebook computer is usually disposed under the body of the notebook computer, that is, the bottom of the notebook computer, it is portable. Electronic devices are also typically provided here. However, due to the design limitation of the lower body of the notebook computer, the heat dissipation direction of the portable electronic device can only dissipate heat to the side or bottom of the lower body of the notebook computer, but the side or bottom of the lower body of the notebook computer is often used. It will be obstructed by obstacles, which will result in poor heat dissipation efficiency. When the heat is dissipated from the side or bottom of the body of the notebook computer, the dissipated heat tends to flow in the direction of the upper body, so that the operating efficiency of the upper body is affected by the dissipated heat. And falling.

Therefore, in order to make the notebook computer have better heat dissipation efficiency and operational efficiency, the position and direction of heat dissipation must be changed, but it is affected by the above design restrictions, except for the side or bottom of the body of the notebook computer. The choice of heat dissipation direction is limited.

The present invention provides a portable electronic device that improves heat dissipation efficiency of the portable electronic device by being disposed at different positions in the electronic device and different heat dissipation directions.

The portable electronic device created by the present invention comprises a first body, a second body, a heat source, a fan and a flip cover. The second body has a rotating shaft pivotally connected to the first body to rotate and open the second body relative to the first body. The heat source is disposed in the first body. The fan is disposed in the first body, and the fan is used to generate airflow and flow through the heat source. The cover is pivotally connected to the first body and is located on the moving path of the rotating shaft, and the cover has at least one opening. When the second body is rotated and deployed relative to the first body by the rotating shaft, the rotating shaft drives the cover relative to The first body rotates, and the airflow flowing through the heat source is dissipated through the opening to escape the first body.

In an embodiment of the present invention, the first body has a rail, and the rotating shaft is movably coupled to the rail to rotate the second body relative to the first body.

In an embodiment of the present invention, the rotation direction of the second body relative to the first body is opposite to the rotation direction of the cover relative to the first body.

In an embodiment of the present invention, the airflow flowing through the heat source dissipates the first body in a direction away from the second body.

In an embodiment of the present invention, the cover has a heat dissipation fin located on the inner surface of the cover and is in thermal contact with the heat source. The fan is used to generate airflow and flows through the heat dissipation fin, and then escapes through the opening. The first machine is outside the body.

In an embodiment of the present invention, the portable electronic device further includes a heat pipe disposed at a pivotal connection between the flip cover and the first body, and the heat pipe is connected to the heat source to transfer heat generated by the heat source to the flip cover.

Based on the above, the cover of the portable electronic device changes its opening direction as the body is deployed, that is, the flow direction of the heat dissipation airflow is changed by the cover. In this way, the airflow radiated through the opening of the flip cover and the heat of the entrainment can be away from the second body, so that the electronic components of the second body can be effectively prevented from being heated, thereby improving the use of the electronic components. Life and performance. At the same time, the cover is located at the second body, that is, away from the user, so that the airflow is not transmitted to the user, and thus does not affect the user. In addition, the portable electronic device can no longer provide an opening for heat dissipation on the peripheral side of the first body due to the configuration of the cover, so that the body design can further move toward a slim profile.

The above described features and advantages of the present invention will become more apparent and understood from the following description.

1 is a schematic diagram of a portable electronic device in accordance with an embodiment of the present invention. FIG. 2 and FIG. 3 respectively illustrate another state of the portable electronic device of FIG. 1 in different perspectives. 4 is a partial cross-sectional view of the portable electronic device of FIG. 1. 5 is a partial cross-sectional view of the portable electronic device of FIG. 2 or 3. Referring to FIG. 1 to FIG. 5 , in the embodiment, the portable electronic device 100 is, for example, a notebook computer, and includes a first body 110 (eg, a host), a second body 120 (eg, a screen), and a heat source H. (for example, a processor or a display wafer), a fan F, and a flip cover 130, wherein the first body 110 has a rail 112 and an air inlet I.

In this embodiment, the air inlet I is disposed in the lower casing 110b of the first body 110 and is used to provide a passage for outside air to enter the first body 110, and is positive for the fan F to introduce air into the first body 110. This is not limited to the type and number of air inlets I and the configuration of the lower casing.

Furthermore, the second body 120 has a rotating shaft 122 pivotally connected to the first body 110. Further, the rotating shaft 122 is movably coupled to the rail 112 to enable the second body 120 to rotate relative to the first body 110. The second body 120 is rotated relative to the first body 110 by the axis X1 as a medium structure that is rotated relative to the second body 120 as the first body 110.

In addition, one end of the flip cover 130 is pivotally connected to the first body 110, for example, freely pivoted relative to the upper casing 110a of the first body 110 along the axis X2, and the other end of the flip cover 130 is located on the moving path of the rotating shaft 122 and Rely on the shaft 122. When the second body 120 is rotated and unfolded relative to the first body 110 by the rotating shaft 122, the cover 130 is opened by the rotation of the rotating shaft 122, for example, from the state of FIG. 4 to FIG. When the second body 120 is rotated and closed relative to the first body 110 by the rotating shaft 122, the cover 130 is closed by the rotating shaft 122, for example, from the state of FIG. 5 to FIG. In this embodiment, the flip cover 130 has at least one opening 132, and the opening 132 is adapted to provide a passage for the air in the first body 110 to escape the first body 110, where the type, number and number of openings 132 are not limited. The configuration on the cover 130.

Based on the above, the fan F inhales the outside air through the air inlet I, and generates the airflow A to flow in the first body 110, wherein the airflow A flows in from the air inlet I at the bottom of the first body 110, as shown in FIG. When the second body 120 is unfolded relative to the first body 110, the cover 130 is also unfolded synchronously, and the opening 130 of the cover 130 is oriented away from the second body 120 (ie, can be regarded as facing away from the second body 120). Therefore, after flowing through the heat source H, the airflow A can further flow out of the first body 110 through the opening 132 to achieve the effect of dissipating heat from the heat source H. . In other words, when the airflow A escapes the upper casing 110a of the first body 110 through the opening 132, it will be away from the second body 120, and thus the second body 120 (screen) will not be affected by heat. To avoid damage to the second body 120. At the same time, the position of the lid 130 is also away from the user, and the dissipated heat will be completely dissipated before reaching the user's position, so that the user is not affected.

Further, as shown in FIG. 2 and FIG. 3, the heat generated by the heat source H is dissipated from the opening 132 through the airflow A. Therefore, the first body 110 of the portable electronic device 100 is as shown in FIG. 2. As shown in FIG. 3, the four sides of the circumference (including one side covered by the second body 120 in the state of FIG. 2 and FIG. 3) do not need to be provided with heat dissipation holes, thereby facilitating the first body 110 to be more light and thin. The shape is designed.

6 is a partial cross-sectional view of a portable electronic device according to another embodiment of the present invention. Referring to FIG. 6 , in the present embodiment, the flip cover 130 further has a heat dissipating fin C1 located on the inner surface of the flip cover 130 and extending from the flip cover 130 toward the inside of the first body 110 . The heat radiating fin C1 is in thermal contact with the heat source H to transfer the heat generated by the heat source H to the flip cover 130, and the contact area with the air flow A is increased by the heat radiating fin C1, thereby increasing the heat dissipation efficiency of the flip cover 130. The type, number and arrangement of the fins C1 are not limited here.

In this embodiment, the cover 130 further includes a heat pipe C2 disposed at a pivotal connection between the cover 130 and the first body 110 and connected to the heat source H. The heat pipe C2 can transfer the heat generated by the heat source H to the cover. 130. The heat generated by the heat source H is transmitted to the cover 130 through the heat pipe C2, so that the heat can be smoothly dissipated to the outside of the first body 110 by the air flow A passing through the heat source H and the heat dissipation fin C1. Here, the heat pipe C2 is structurally connected between the heat source H and the pivot 134 of the flip cover 130, and in another embodiment not shown, the heat pipe can also be directly disposed on the pivot, even as a pivot. use.

In addition, by changing the inclination angle of the opening 132 with respect to the surface of the lid 130, the airflow A flowing through the heat source H can be made to escape the dissipation direction of the airflow A flowing through the heat source H when the airflow A flowing through the opening 132 is dissipated outside the first body 110. . The airflow A flowing through the heat source H dissipates the first body 110 in a direction away from the second body 120.

In summary, in the above embodiment of the present invention, the heat dissipation direction of the portable electronic device is changed by the cover, and when the user operates the portable electronic device, the airflow flowing through the heat source passes through the cover. The opening is dissipated in a direction away from the second body, so that the heat dissipated by the airflow will also deviate from the second body, so that the operating performance of the second body is not affected by the heat. At the same time, since the cover is located adjacent to the first body of the second body, the dissipated heat is completely dissipated before reaching the position of the user, so that the user is not affected by the heat, so that the portable electronic device is The heat dissipation layout combines its heat dissipation efficiency with protective components and reduces the impact on the user.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the novel creation, and any person skilled in the art can make some changes without departing from the spirit and scope of the novel creation. Retouching, the scope of protection of this new creation is subject to the definition of the scope of the patent application attached.
