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

<FIG> and <FIG> are schematic diagrams of a portable electronic device in a first state and a second state, respectively, of an embodiment of the invention. <FIG> and <FIG> are schematic side views of the portable electronic device of <FIG> and <FIG>, respectively. Referring to <FIG>, in the present embodiment, a portable electronic device <NUM> may be a notebook computer, and includes a first body <NUM>, a second body <NUM>, a third body <NUM>, a first hinge 140a, a second hinge 140b, and an input module <NUM>. The second body <NUM> is disposed between the first body <NUM> and the third body <NUM>, wherein the second body <NUM> is pivotally connected to the first body <NUM> via the first hinge 140a, and the third body <NUM> is pivotally connected to the second body <NUM> via the second hinge 140b. That is, the first body <NUM> is adapted to be rotated relative to the second body <NUM> via the first hinge 140a, and the second body <NUM> is adapted to be rotated relative to the third body <NUM> via the second hinge 140b.

As shown in <FIG> and <FIG>, the input module <NUM> is slidably disposed on the third body <NUM> and covers the second body <NUM> and the second hinge 140b. When the second body <NUM> and the second hinge 140b are covered by the input module <NUM>, the second body <NUM> temporarily may not be rotated relative to the third body <NUM> via the second hinge 140b. In the state shown in <FIG> and <FIG>, the first body <NUM> may be rotated relative to the second body <NUM> via the first hinge 140a to adjust the angle thereof (e.g., viewing angle).

In the present embodiment, the input module <NUM> includes a keyboard <NUM> and a touch pad <NUM>, and the keyboard <NUM> is located between the first hinge 140a and the touch pad <NUM>. In other embodiments, the input module may include any one of a keyboard, a touch panel, and a touch display, or a combination of at least two of the above.

As shown in <FIG> and <FIG>, when the input module <NUM> is slid close to the first hinge 140a, the input module <NUM> covers the second body <NUM>, the second hinge 140b, and the third body <NUM>, and therefore the second body <NUM> temporarily may not be rotated relative to the third body <NUM> via the second hinge 140b. Moreover, the first body <NUM> may be rotated relative to the second body <NUM> via the first hinge 140a to adjust the angle thereof (e.g., viewing angle). That is, the first body <NUM> is adapted to be unfolded or closed to the second body <NUM> via the first hinge 140a.

As shown in <FIG> and <FIG>, when the input module <NUM> is slid away from the first hinge 140a, the second body <NUM> and the second hinge 140b are moved out from under the input module <NUM> to be exposed to the outside, but the third body <NUM> is still covered by the input module <NUM>. After the second body <NUM> and the second hinge 140b are moved out of the input module <NUM> without being covered by the input module <NUM>, the second body <NUM> may be rotated relative to the third body <NUM> via the second hinge 140b to adjust the angle thereof (e.g., viewing angle). Moreover, the angle (e.g., viewing angle) and height (e.g., viewing height) of the first body <NUM> may be adjusted synchronously with the rotation of the second body <NUM>, or the angle (e.g., viewing angle) of the first body <NUM> may be adjusted independently. That is, the first body <NUM> is adapted to be unfolded or closed to the second body <NUM> via the first hinge 140a, and the second body <NUM> is adapted to be unfolded or closed to the third body <NUM> via the second hinge 140b.

As shown in <FIG> and <FIG>, the first body <NUM> has a first display area <NUM>, and the second body <NUM> has a second display area <NUM>. The first display area <NUM> and the second display area <NUM> are separated from each other, and the first hinge 140a is located between the first display area <NUM> and the second display area <NUM>. In detail, the first display area <NUM> and the second display area <NUM> form at least a portion of the display, wherein the first display area <NUM> may be used as a main display area, and the second display area <NUM> may be used as an auxiliary display area.

As shown in <FIG> and <FIG>, when the input module <NUM> is slid close to the first hinge 140a, the input module <NUM> covers the second display area <NUM>, and the user may view the screen displayed on the first display area <NUM> of the first body <NUM>. At this time, the angle of the first body <NUM> is adjustable to adjust the viewing angle of the first display area <NUM>.

As shown in <FIG> and <FIG>, when the input module <NUM> is slid away from the first hinge 140a, the second body <NUM> is moved out of the input module <NUM> so that the second display area <NUM> of the second body <NUM> is not covered by the input module <NUM> and is exposed to the outside. Therefore, the user may view the screen displayed in the first display area <NUM> and the screen displayed in the second display area <NUM> at the same time. At this time, the angle of the second body <NUM> is adjustable to adjust the viewing angle of the second display area <NUM>, and, the angle and height of the first body <NUM> may be adjusted synchronously with the rotation of the second body <NUM>, so as to adjust the viewing angle and viewing height of the first display area <NUM>, or, the angle of the first body <NUM> may be adjusted independently to adjust the viewing angle of the first display area <NUM>.

Therefore, the user may slide the input module <NUM> according to operation requirements to increase or decrease the number of display areas or scale the size of the display areas, thus achieving excellent operation flexibility. Moreover, since the viewing angle and viewing height of the first display area <NUM> are adjustable, and the viewing angle of the second display area <NUM> is adjustable, not only are the flexibility and comfort of operation improved, the user's operating experience is also improved.

For example, the second body <NUM> may be entirely or partially moved out from under input module <NUM> as the input module <NUM> is slid away from the second hinge 140b. When the second body <NUM> is partially moved out of the input module <NUM>, the first display area <NUM> may be used as a main display area, and a part of the second display area <NUM> located outside of the input module <NUM> may be used as an auxiliary display area.

Referring to <FIG> and <FIG>, in the present embodiment, the portable electronic device <NUM> further includes a sensor <NUM> disposed in the second body <NUM> and configured to sense whether the input module <NUM> covers the second body <NUM>. As shown in <FIG> and <FIG>, when the input module <NUM> is slid close to the first hinge 140a, the sensor <NUM> senses that the input module <NUM> covers the second body <NUM> and the second display area <NUM> is in a sleep state or a disabled state. As shown in <FIG> and <FIG>, when the input module <NUM> is slid away from the first hinge 140a, the sensor <NUM> senses that the second body <NUM> is moved out of the input module <NUM> and exposed to the outside, and the second display area <NUM> is awakened from the sleep state and switched to a wake-up or enabled state.

For example, the sensor <NUM> may be a touch sensor or a proximity sensor, wherein the sensing mechanism of the touch sensor is based on whether the input module <NUM> is in contact with the second body <NUM>. In addition, the sensing mechanism of the proximity sensor is based on changes in light, capacitance, inductance, magnetic field, or the like caused by the sliding of the input module <NUM>. In other embodiments, the sensor may be disposed in the input module, or both the second body and the input module may be provided with a sensor.

As shown in <FIG> and <FIG>, in the present embodiment, the portable electronic device <NUM> further includes a speaker <NUM>, wherein the speaker <NUM> is disposed in the input module <NUM> to slide close to the first hinge 140a or slide away from the first hinge 140a along with the input module <NUM>. When the input module <NUM> is slid close to the first hinge 140a, the speaker <NUM> is accommodated in the first body <NUM>. When the input module <NUM> is slid away from the first hinge 140a, the speaker <NUM> is moved out of the third body <NUM>, in order to avoid the degradation of the sound performance of the speaker <NUM> due to the interference of the casing of the third body <NUM> or the components in the casing, thus improving the user's operating experience.

<FIG> is a schematic side view of the portable electronic device of <FIG> converted to a third state. IF is a schematic side view of the portable electronic device of <FIG> converted to a fourth state. Referring to <FIG>, when the input module <NUM> is slid away from the first hinge 140a, the second body <NUM> is moved out of the input module <NUM> so that the second display area <NUM> of the second body <NUM> is not covered by the input module <NUM> and is exposed to the outside. Therefore, the user may view the screen displayed in the first display area <NUM> and the screen displayed in the second display area <NUM> at the same time. At this time, the angle of the second body <NUM> is adjustable to adjust the viewing angle of the second display area <NUM>, and, the angle and height of the first body <NUM> may be adjusted synchronously with the rotation of the second body <NUM>, so as to adjust the viewing angle and viewing height of the first display area <NUM>, or, the angle of the first body <NUM> may be adjusted independently to adjust the viewing angle of the first display area <NUM>.

In the present embodiment, the portable electronic device <NUM> further includes a bottom plate <NUM> disposed at the bottom of the third body <NUM>, and the second body <NUM> and the third body <NUM> are disposed on the bottom plate <NUM>. As shown in <FIG>, when the input module <NUM> is slid close to the first hinge 140a, the second body <NUM> is closed at the bottom plate <NUM>. On the contrary, when the input module <NUM> is slid away from the first hinge 140a, the second body <NUM> is adapted to be unfolded or closed at the bottom plate <NUM> via the second hinge 140b. As shown in <FIG> and <FIG>, after the first body <NUM> and the second body <NUM> are rotated and lifted relative to the third body <NUM>, the bottom plate <NUM> and the third body <NUM> may stably support the first body <NUM> and the second body <NUM> to prevent the portable electronic device <NUM> from shaking or falling.

As shown in <FIG>, a width 130W of the third body <NUM> is less than a width 180W of the bottom plate <NUM>, and the width 180W of the bottom plate <NUM> is less than the sum of a width 120W of the second body <NUM> and the width 130W of the third body <NUM>.

As shown in <FIG>, the portable electronic device <NUM> further includes a camera <NUM> disposed on the first body <NUM>, and the first hinge 140a is disposed between the camera <NUM> and the second hinge 140b. When the input module <NUM> is slid close to the first hinge 140a, the camera <NUM> and the first body <NUM> are adapted to adjust a shooting angle <NUM> and a shooting height <NUM> via the first hinge 140a. That is to say, the shooting angle <NUM> and the shooting height <NUM> of the camera <NUM> may be adjusted according to the rotation of the first body <NUM>. As shown in <FIG>, when the input module <NUM> is slid away from the first hinge 140a, the camera <NUM>, the first body <NUM>, and the second body <NUM> are adapted to adjust the shooting angle <NUM> and the shooting height <NUM> via the first hinge 140a and the second hinge 140b. That is to say, the shooting angle <NUM> and the shooting height <NUM> of the camera <NUM> may be adjusted according to the rotation of the first body <NUM> or the second body <NUM>.

<FIG> is a schematic diagram of a portable electronic device of another embodiment of the invention. Referring to <FIG>, unlike the portable electronic device <NUM> shown in <FIG>, a portable electronic device 100A of the present embodiment further includes a functional member <NUM>, wherein the functional member <NUM> is disposed on the second body <NUM> and includes a camera 103a, a microphone 103b, and a speaker 103c. For example, the second display area <NUM> may be a portion of the functional member <NUM>, and the camera 103a, the microphone 103b, and the speaker 103c are located on the same side of the second display area <NUM>. When the input module <NUM> is slid away from the first hinge 140a, the second display area <NUM>, the camera 103a, the microphone 103b, and the speaker 103c are not covered by the input module <NUM> and are exposed to the outside. Conversely, when the input module <NUM> is slid close to the first hinge 140a, the second display area <NUM>, the camera 103a, the microphone 103b, and the speaker 103c are covered by the input module <NUM>. Moreover, the type or quantity of the functional member <NUM> may be adjusted according to design requirements.

<FIG> and <FIG> are schematic side views of a portable electronic device in a first state and a second state, respectively, of another embodiment of the invention. Please refer to <FIG> and <FIG>. Unlike the portable electronic device <NUM> shown in <FIG> and <FIG>, a portable electronic device 100B of the present embodiment further includes a heat dissipation module <NUM> disposed in the third body <NUM>, and the third body <NUM> has an air outlet <NUM> on a side away from the first hinge 140a. When the input module <NUM> is slid close to the first hinge 140a, the input module <NUM> covers the air outlet <NUM>. On the contrary, when the input module <NUM> is slid away from the first hinge 140a, the air outlet <NUM> is not covered by the input module <NUM> and is exposed to the outside. As shown in <FIG>, the air outlet <NUM> not covered by the input module <NUM> and exposed to the outside may be used as another heat dissipation path of the heat dissipation module <NUM> (for example, an exhaust path of hot air), thus not only improving the heat dissipation efficiency of the portable electronic device 100B, but also improving the performance of the portable electronic device 100B.

<FIG> are schematic side views of a portable electronic device in a first state to a fourth state, respectively, of another embodiment of the invention. Please refer to <FIG>. Unlike the portable electronic device <NUM> shown in <FIG>, in the present embodiment, a portable electronic device 100C includes a flexible display <NUM> disposed on the first body <NUM> and the second body <NUM>, wherein the flexible display <NUM> covers the first hinge 140a and has a first display area <NUM> corresponding to the first body <NUM> and a second display area <NUM> corresponding to the second body <NUM>. Further, the first display area <NUM> and the second display area <NUM> are connected to each other, and as the first body <NUM> is rotated relative to the second body <NUM>, a section in the flexible display <NUM> corresponding to the first hinge 140a (i.e., the section located in the first display area <NUM> and the second display area <NUM>) may be bent accordingly.

As shown in <FIG> and <FIG>, when the input module <NUM> is slid close to the first hinge 140a, the first display area <NUM> and the first body <NUM> are adapted to adjust the angle via the first hinge 140a. That is to say, the viewing angle of the first display area <NUM> may be adjusted with the rotation of the first body <NUM>. As shown in <FIG>, when the input module <NUM> is slid away from the first hinge 140a, the first display area <NUM>, the first body <NUM>, the second display area <NUM>, and the second body <NUM> are adapted to adjust the angle and height via the first hinge 140a and the second hinge 140b. That is, the viewing angle and viewing height of the first display area <NUM> and the second display area <NUM> may be adjusted according to the rotation of the first body <NUM> or the second body <NUM>. As shown in <FIG>, the included angle between the first display area <NUM> and the second display area <NUM> is equal to <NUM> degrees, and the flexible display <NUM> is in a flat state.

<FIG> is a schematic diagram of the portable electronic device of <FIG> from another viewing angle. Referring to <FIG>, a length X1 of the first display area <NUM> is equal to a length X2 of the second display area <NUM>, and a width Y1 of the first display area <NUM> is greater than a width Y2 of the second display area <NUM>. In an embodiment, the ratio of the length X1 to the width Y1 of the first display area <NUM> is <NUM>:<NUM>, and the ratio of the length X2 to the width Y2 of the second display area <NUM> is <NUM>:<NUM>. In addition, the ratio of the length X1 to the width (Yl+Y2) of the first display area <NUM> and the second display area <NUM> is <NUM>:<NUM>. In another embodiment, the ratio of the length X1 to the width Y1 of the first display area <NUM> is <NUM>:<NUM>, and the ratio of the length X2 to the width Y2 of the second display area <NUM> is <NUM>:<NUM>. In addition, the ratio of the length X1 to the width (Y1+Y2) of the first display area <NUM> and the second display area <NUM> is <NUM>:<NUM>.

In the portable electronic device <NUM> and the portable electronic devices 100A to 100C of the above embodiments, a first sensor and a second sensor configured to sense the included angle between the first body <NUM> and the second body <NUM> may be further disposed on the first body <NUM> and the second body <NUM>, respectively. The following is an example of the portable electronic device 100C.

Referring to <FIG>, a first sensor <NUM> is disposed inside the first body <NUM>, and a second sensor <NUM> is disposed inside the second body <NUM>. The first sensor <NUM> and the second sensor <NUM> include a gyroscope, a gravity sensor, or a magnetometer configured to sense the included angle between the first body <NUM> and the second body <NUM>. As the included angle between the first body <NUM> and the second body <NUM> is changed, the first display area <NUM> and the second display area <NUM> may be switched between different display modes, or, when the included angle between the first body <NUM> and the second body <NUM> remains unchanged, the display modes of the first display area <NUM> and the second display area <NUM> are switched based on the operation command.

For example, when the display ratio of the display content of the display is equal to the display ratio of the first display area <NUM> plus the second display area <NUM> (for example, <NUM>:<NUM>), and when the included angle between the first body <NUM> and the second body <NUM> is less than <NUM> degrees, the functional member prompts the user to adjust the included angle to <NUM> degrees. In addition, when the display ratio of the display content of the display is equal to the display ratio of the first display area <NUM> (for example, <NUM>:<NUM>), and the included angle between the first body <NUM> and the second body <NUM> is equal to <NUM> degrees, the functional member prompts the user to adjust the included angle to less than <NUM> degrees. The functional member may be a speaker or a display prompting the user to adjust the included angle between the first body <NUM> and the second body <NUM> via sound or video.

<FIG> is a schematic diagram of a control flow of the display modes of a first display area and a second display area. <FIG> are schematic diagrams of a first display area and a second display area in a first display mode to a fourth display mode, respectively. Referring to <FIG> and <FIG>, when it is sensed that the included angle between the first body <NUM> and the second body <NUM> is less than <NUM> degrees, the first display area <NUM> and the second display area <NUM> are switched to the first display mode. In the first display mode, the first display area <NUM> displays a first screen S1 (e.g., a portrait of a participant), and the second display area <NUM> displays a second screen S2 (e.g., information such as text, image, or video), as shown in <FIG>.

Please refer to <FIG>, <FIG>, and <FIG>, when the first operation command is received, the display modes of the first display area <NUM> and the second display area <NUM> may be switched from the first display mode to the second display mode or switched back to the first display mode. In the second display mode, the first display area <NUM> displays the second screen S2 (for example, information such as text, image, or video), and the second display area <NUM> displays the first screen S1 (e.g., the portrait of a participant), as shown in <FIG>. In other embodiments, the first screen S1 displayed in the display area <NUM> may be a main application screen, such as a webpage or a commonly used application program screen. On the other hand, the second screen S2 displayed in the second display area <NUM> may include shortcuts or icons of multiple applications.

Please refer to <FIG>, <FIG>, and <FIG>, when the second operation command is received, the display modes of the first display area <NUM> and the second display area <NUM> may be switched from the first display mode to the third display mode or switched back to the first display mode. In the third display mode, the first display area <NUM> displays a third screen S3 (e.g., a screen sharing screen), and the second display area <NUM> displays the first screen S1 (e.g., a portrait of a participant), as shown in <FIG>.

Please refer to <FIG>, <FIG>, and <FIG>, when the display modes of the first display area <NUM> and the second display area <NUM> are in the second display mode or the third display mode, and a third operation command is received, the first display area <NUM> and the second display area <NUM> in the second display mode may be switched to the third display mode. Conversely, the first display area <NUM> and the second display area <NUM> in the third display mode may be switched to the second display mode.

Referring to <FIG> and <FIG>, when it is sensed that the included angle between the first body <NUM> and the second body <NUM> is equal to <NUM> degrees, the first display area <NUM> and the second display area <NUM> are switched to the fourth display mode. In the fourth display mode, the first display area <NUM> and the second display area <NUM> jointly display a fourth screen S4, that is, the display ratio of the display content is equal to the display ratio of the first display plus the second display, such as the preset split screen of the application. In the preset split screen of the application, the left half may display the portrait of the participant, while the right half may display information such as text, image, or video. In other embodiments, the first display area <NUM> and the second display area <NUM> display a common screen, and the common screen may include computer desktop and shortcuts or icons of multiple applications, and the positions of the shortcuts or icons of the applications on the computer desktop may be adjusted according to the operation requirements of the user.

Based on the above, in the portable electronic device of the invention, the user may slide the input module according to the operation requirements, so that the second body is covered by the input module or removed from the input module to flexibly switch the operation mode, thus achieving excellent operation flexibility. Further, when the second body is covered by the input module, the angle of the first body may be adjusted. After the second body is removed from the input module, the angle of the second body may be adjusted, and the angle and height of the first body may be adjusted synchronously with the rotation of the second body, or the angle of the first body may be adjusted independently. Therefore, the portable electronic device not only improves the flexibility and comfort in operation, but also improves the user's operating experience.

In an embodiment, the first body has a first display area, and the second body has a second display area. When the second display area of the second body is covered by the input module, the user may view the screen displayed by the first display area of the first body. At this time, the angle of the first body is adjustable to adjust the viewing angle of the first display area. After the second body is removed from the input module, the second display area of the second body is not covered by the input module and is exposed to the outside. Therefore, the user may view the screen displayed in the first display area and the screen displayed in the second display area at the same time. At this time the angle of the second body is adjustable to adjust the viewing angle of the second display area, and, the angle and height of the first body may be adjusted synchronously with the rotation of the second body, so as to adjust the viewing angle and viewing height of the first display area, or, the angle of the first body may be adjusted independently to adjust the viewing angle of the first display area. In other words, the user may slide the input module according to operation requirements to increase or decrease the number of display areas or scale the size of the display areas, thus achieving excellent operation flexibility. Moreover, since the viewing angle and viewing height of the first display area are adjustable, and the viewing angle of the second display area is adjustable, not only are the flexibility and comfort of operation improved, the user's operating experience is also improved.

In another embodiment, the speaker module may be slid along with the input module and moved out of the third body, in order to avoid the degradation of the sound performance of the speaker due to the interference of the casing of the third body or the components in the casing, thus improving the user's operating experience.
