Description

Portable electronic devices

The present invention relates to an electronic device, and in particular to a portable electronic device.

A laptop computer is composed of a first body and a second body that are connected to each other, wherein the first body is a host with a logical computing function, and the second body is a display with an image display function. Specifically, a central processing unit and a graphics processing unit are provided inside the first body. With the improvement of computing performance and the increase of computing volume, the central processing unit and the graphics processing unit will release a lot of heat when running.

Generally speaking, the first body is provided with heat pipes, fans and heat sinks, wherein the heat pipes are used to transfer the heat generated by the CPU and the GPU to the heat sinks, and the fans are used to introduce cold air from the outside into the first body. Then, the fans blow the cold air to the heat sinks for heat exchange, and finally, the hot air formed after the heat exchange is discharged outside the first body to prevent heat accumulation inside the first body and cause the CPU and GPU computing performance to decline. Specifically, the cold air is usually taken in from the bottom opening of the first body, and the hot air is usually exhausted from the side opening or the rear opening of the first body, but the existing intake and exhaust volumes are difficult to cope with the heat discharged by the CPU and GPU for efficient computing, so the heat dissipation efficiency is poor.

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

The present invention proposes a portable electronic device, including a first body, a second body, a rotating shaft module and a driving module. The first body includes a top and a movable cover pivotally connected to the top. The rotating shaft module includes a rotating shaft, a first bracket fixed to the first body and a second bracket fixed to the second body, wherein the second bracket is fixed to the rotating shaft, and the rotating shaft is pivotally connected to the first bracket. The driving module is arranged in the first body, and includes a first gear fixed to the rotating shaft, a second gear engaged with the first gear, a driving member, a driven member coupled to the driving member and a lifting mechanism connected to the driven member, wherein the driving member is arranged on one side of the second gear and rotates synchronously with the second gear in the same direction. The lifting mechanism contacts the movable cover, wherein the driving member has a first protrusion, and the follower has a first concave portion located on the moving path of the first protrusion. When the second body rotates and expands to a first angle relative to the first body, the first protrusion engages with the first concave portion. When the second body rotates and expands to a second angle greater than the first angle relative to the first body, the driving member drives the follower to rotate through the engagement of the first protrusion and the first concave portion, and the follower drives the lifting mechanism to lift and drive the movable cover to open relative to the top. When the second body rotates and closes to less than the first angle relative to the first body, the first protrusion separates from the first concave portion, and the driving member stops driving the follower to rotate, so as to stop driving the lifting mechanism to lift, thereby fixing the closed state of the movable cover.

In one embodiment of the present invention, when the second body is closed to the first body, the first convex part is separated from the first concave part.

In one embodiment of the present invention, when the second body rotates and expands relative to the first body to a greater than second angle, the first convex portion separates from the first concave portion, the follower stops rotating, and stops driving the lifting mechanism to lift.

In one embodiment of the present invention, the above-mentioned driving member further has a second convex portion, and the driven member further has a second concave portion corresponding to the second convex portion. When the second body is closed to the first body, the second convex portion is engaged with the second concave portion. When the second body rotates and unfolds to the first angle relative to the first body, the second convex portion separates from the second concave portion.

In one embodiment of the present invention, when the second body rotates and closes from the second angle to the first angle relative to the first body, the first protrusion engages with the first concave portion, and the driving member drives the follower to rotate through the engagement of the first protrusion and the first concave portion, and the follower drives the lifting mechanism to descend to drive the movable cover to rotate relative to the top. When the second body rotates and closes to the first angle relative to the first body, the movable cover closes at the top.

In one embodiment of the present invention, the lifting mechanism includes a first link, a second link and a lifting member. The first link is pivotally connected to the follower, and the opposite ends of the second link are pivotally connected to the first bracket and the first link respectively. The lifting member is slidably connected to the first link and fixedly connected to the movable cover.

In one embodiment of the present invention, the first body further includes two auxiliary movable panels pivotally connected to the top, and the two auxiliary movable panels are respectively located on opposite sides of the movable cover. The opposite sides of the movable cover are respectively coupled to the two auxiliary movable panels.

The present invention proposes another portable electronic device, including a first body, a second body, a shaft module and a drive module. The first body includes a bottom and a movable cover pivotally connected to the bottom. The shaft module includes a shaft, a first bracket fixed to the first body and a second bracket fixed to the second body, wherein the second bracket is fixed to the shaft, and the shaft is pivotally connected to the first bracket. The drive module is arranged in the first body, and includes a first gear fixed to the shaft, a second gear coupled to the first gear, a driving member, a driven member coupled to the driving member and a lifting mechanism connected to the driven member, wherein the driving member is arranged on one side of the second gear and rotates synchronously with the second gear in the same direction. The lifting mechanism contacts the movable cover, wherein the driving member has a first protrusion, and the follower has a first concave portion located on the moving path of the first protrusion. When the second body rotates and expands to a first angle relative to the first body, the first protrusion engages with the first concave portion. When the second body rotates and expands to a second angle greater than the first angle relative to the first body, the driving member drives the follower to rotate through the engagement of the first protrusion and the first concave portion, and the follower drives the lifting mechanism to descend to drive the movable cover to rotate relative to the bottom. When the second body rotates and closes to less than the first angle relative to the first body, the first protrusion separates from the first concave portion, and the driving member stops driving the follower to rotate, so as to stop driving the lifting mechanism to descend, thereby fixing the closed state of the movable cover.

In another embodiment of the present invention, when the second body rotates and expands relative to the first body to a value greater than the second angle, the first convex portion separates from the first concave portion, the follower stops rotating, and stops driving the lifting mechanism to descend.

In another embodiment of the present invention, when the second body rotates and closes from the second angle to the first angle relative to the first body, the first protrusion engages with the first recess, and the driving member drives the follower to rotate through the engagement of the first protrusion and the first recess, and the follower drives the lifting mechanism to lift and drive the movable cover to rotate relative to the bottom. When the second body rotates and closes to the first angle relative to the first body, the movable cover is closed at the bottom.

In another embodiment of the present invention, the lifting mechanism includes a first link, a second link, a third link and a lifting member, and the first link is pivoted on the first bracket. One end of the first link is pivoted to the follower, and one end of the second link is pivoted to the first bracket. The other end of the first link and the other end of the second link are pivoted to the third link. The lifting member is slidably connected to the third link and fixed to the movable cover.

In another embodiment of the present invention, the first body further includes two auxiliary movable plates pivotally connected to the bottom, and the two auxiliary movable plates are respectively located on opposite sides of the movable cover. The opposite sides of the movable cover are pivotally connected to the two auxiliary movable plates.

The present invention proposes another portable electronic device, including a first body, a second body, a rotating shaft module and a driving module. The first body includes a top, a first movable cover pivotally connected to the top, a bottom and a second movable cover pivotally connected to the bottom. The rotating shaft module includes a rotating shaft, a first bracket fixed to the first body and a second bracket fixed to the second body, wherein the second bracket is fixed to the rotating shaft, and the rotating shaft is pivotally connected to the first bracket. The driving module is arranged in the first body, and includes a first gear fixed to the rotating shaft, a second gear engaged with the first gear, a driving member, a driven member coupled to the driving member, and a first lifting mechanism and a second lifting mechanism connected to the driven member, wherein the driving member is arranged on one side of the second gear and rotates synchronously with the second gear in the same direction. The first lifting mechanism contacts the first movable cover, and the second lifting mechanism contacts the second movable cover. The driving member has a first protrusion, and the driven member has a first concave portion located on the moving path of the first protrusion. When the second body rotates and expands to a first angle relative to the first body, the first protrusion engages with the first concave portion. When the second body rotates and expands to a second angle greater than the first angle relative to the first body, the driving member drives the driven member to rotate through the engagement of the first protrusion and the first concave portion. The driven member drives the first lifting mechanism to rise to drive the first movable cover to unscrew relative to the top, and simultaneously drives the second lifting mechanism to descend to drive the second movable cover to unscrew relative to the bottom. When the second body rotates and closes relative to the first body to a degree less than the first angle, the first convex portion separates from the first concave portion, and the driving member stops driving the driven member to rotate, thereby synchronously stopping driving the first lifting mechanism to descend and the second lifting mechanism to ascend, thereby fixing the closed state of the first movable cover and the second movable cover.

In another embodiment of the present invention, when the second body rotates and expands relative to the first body to a greater than second angle, the first convex portion separates from the first concave portion, the follower stops rotating, and simultaneously stops driving the first lifting mechanism to lift and the second lifting mechanism to descend.

In another embodiment of the present invention, when the second body rotates and closes from the second angle to the first angle relative to the first body, the first protrusion engages with the first concave portion, and the driving member drives the follower to rotate through the engagement of the first protrusion and the first concave portion. The follower drives the first lifting mechanism down to drive the first movable cover to rotate relative to the top, and simultaneously drives the second lifting mechanism up to drive the second movable cover to rotate relative to the bottom. When the second body rotates and closes to the first angle relative to the first body, the first movable cover is closed at the top, and the second movable cover is closed at the bottom.

In another embodiment of the present invention, the first body further includes two first auxiliary movable panels pivoted at the top and two second auxiliary movable panels pivoted at the bottom. The two first auxiliary movable panels are respectively located at opposite sides of the first movable cover, and the opposite sides of the first movable cover are respectively coupled to the two first auxiliary movable panels. The two second auxiliary movable panels are respectively located at opposite sides of the second movable cover, and the opposite sides of the second movable cover are respectively pivoted to the two second auxiliary movable panels.

Based on the above, at least one of the top and bottom of the first body is provided with a movable cover. When the second body rotates and unfolds relative to the first body, the movable cover can be unscrewed to form an auxiliary air intake opening to increase the intake volume of cold air flowing into the first body, or the movable cover can be unscrewed to form an auxiliary air exhaust opening to increase the exhaust volume of hot air discharged from the first body. By increasing the intake volume of cold air or the exhaust volume of hot air, the heat generated inside the first body can be discharged faster, greatly improving the heat dissipation efficiency of the portable electronic device of the present invention.

In order to make the above features and advantages of the present invention more clearly understood, the following is a detailed description of the embodiments with the accompanying drawings.

FIG. 1B is a schematic diagram of the portable electronic device in FIG. 1A at other viewing angles. FIG. 2A is a schematic diagram of the portable electronic device in FIG. 1A being switched to a second state. Referring to FIG. 1A and FIG. 2A, in this embodiment, the portable electronic device 100 may be a notebook computer and includes a first body 110 and a second body 120 connected to each other. Specifically, the first body 110 may be a host having a logic operation function, and the second body 120 may be a display having an image display function. The second body 120 may be rotated to be unfolded or rotated to be closed relative to the first body 110 to switch between the first state and the second state.

For example, in the first state, the laptop is in a closed state, and the angle between the first body 110 and the second body 120 may be 0 degrees. In contrast, in the second state, the laptop is in an unfolded state and has a better viewing angle. For example, in the second state, the angle between the first body 110 and the second body 120 may be 135 degrees, but is not limited thereto.

FIG. 2B and FIG. 2C are schematic diagrams of the portable electronic device of FIG. 2A at other viewing angles. Next, referring to FIG. 1A, FIG. 1B, FIG. 2B and FIG. 2C, when the second body 120 is rotated and unfolded relative to the first body 110 to switch to the second state, a top opening 1111 may be formed at the rear side of the top 111 of the first body 110, and a bottom opening 1121 may be formed at the rear side of the bottom 112 of the first body 110. Further, the top opening 1111 may be a slit formed at the rear side of the top 111, and the bottom opening 1121 may be a slit formed at the rear side of the bottom 112. As the second body 120 rotates and expands relative to the first body 110, the top opening 1111 and the bottom opening 1121 can be formed synchronously. Conversely, as the second body 120 rotates and closes relative to the first body 110, the top opening 1111 and the bottom opening 1121 can be removed or closed synchronously.

In one example, the top opening 1111 and the bottom opening 1121 serve as auxiliary air intake openings to increase the amount of cold air flowing into the first body 110. In another example, the top opening 1111 and the bottom opening 1121 serve as auxiliary air exhaust openings to increase the amount of hot air discharged from the first body 110. By increasing the amount of cold air intake or the amount of hot air exhaust, the heat generated inside the first body 110 can be discharged faster, greatly improving the heat dissipation efficiency of the portable electronic device 100.

FIG. 3A is a partial cross-sectional schematic diagram of the portable electronic device of FIG. 1A along the section line I-I. FIG. 3B to FIG. 3D are partial cross-sectional schematic diagrams of the portable electronic device of FIG. 3A switching from the first state to the second state. As shown in FIG. 1B, FIG. 2B, FIG. 2C and FIG. 3A, the first body 110 includes a first movable cover 113 and a second movable cover 114, wherein the first movable cover 113 is hinged to the top 111, and the second movable cover 114 is hinged to the bottom 112.

As shown in FIGS. 2A to 2C or as shown in FIGS. 3A to 3D, as the second body 120 rotates and unfolds relative to the first body 110, the first movable cover 113 can be lifted up and rotated relative to the top 111 to form a top opening 1111 at the top 111. At the same time, the second movable cover 114 can be pressed down and rotated relative to the bottom 112 to form a bottom opening 1121 at the bottom 112. Conversely, as the second body 120 rotates and closes relative to the first body 110, the first movable cover 113 can be pulled down and rotated relative to the top 111 to remove or close the top opening 1111. At the same time, the second movable cover 114 can be pulled up and screwed relative to the bottom 112 to remove or close the bottom opening 1121.

It is particularly noted that, during the process of the second body 120 rotating to open or close relative to the first body 110, the first movable cover 113 and the second movable cover 114 rotate in opposite directions.

As shown in FIGS. 2A to 2C , the first body 110 further includes two first auxiliary movable panels 115 pivoted to the top 111 and two second auxiliary movable panels 116 pivoted to the bottom 112. In detail, the two first auxiliary movable panels 115 are respectively located at opposite sides of the first movable cover 113, and the opposite sides of the first movable cover 113 are respectively coupled to the two first auxiliary movable panels 115. For example, the opposite sides of the first movable cover 113 may be pivoted to or in contact with the two first auxiliary movable panels 115, or in other words, the two first auxiliary movable panels 115 may be respectively abutted against the opposite sides of the first movable cover 113. Therefore, the first movable cover 113 can synchronously drive the two first auxiliary movable plates 115 to open or close relative to the top 111.

On the other hand, the two second auxiliary movable plates 116 are respectively located on opposite sides of the second movable cover 114, and the opposite sides of the second movable cover 114 are respectively pivoted to the two second auxiliary movable plates 116. Therefore, the second movable cover 114 can synchronously drive the two second auxiliary movable plates 116 to open or close relative to the bottom 112.

FIG. 4A and FIG. 4B are schematic diagrams of a shaft module and a driving module in a first state at two different viewing angles according to an embodiment of the present invention. FIG. 5A and FIG. 5B are schematic diagrams of a shaft module and a driving module in a second state at two different viewing angles according to an embodiment of the present invention. Please refer to FIG. 3A, FIG. 4A and FIG. 4B. In this embodiment, the portable electronic device 100 further includes a shaft module 130 and a driving module 140, wherein the second body 120 is pivotally connected to the first body 110 through the shaft module 130, and the driving module 140 is connected to the shaft module 130, so that the shaft module 130 generates a driving force for the driving module 140.

As shown in FIG. 3A, FIG. 3D, FIG. 4A and FIG. 5A, the shaft module 130 includes a shaft 131, a first bracket 132 fixed to the first body 110 and a second bracket 133 fixed to the second body 120, wherein the second bracket 133 is fixed to the shaft 131, and the shaft 131 is pivoted to the first bracket 132. When the second body 120 rotates relative to the first body 110, the second bracket 133 and the shaft 131 rotate synchronously with the second body 120, and the shaft 131 rotates relative to the first bracket 132.

As shown in FIG. 3A , FIG. 4A and FIG. 4B , the driving module 140 is disposed in the first body 110 and includes a first gear 141 fixed to the rotating shaft 131, a second gear 142 engaged with the first gear 141, a driving member 143, a driven member 144 coupled to the driving member 143, and a first lifting mechanism 145 and a second lifting mechanism 146 connected to the driven member 144. The first gear 141, the second gear 142, the driving member 143 and the driven member 144 may be pivotally mounted on the first bracket 132, wherein the driving member 143 is disposed on one side of the second gear 142 and is coaxially disposed with the second gear 142. In detail, the first gear 141 can transmit the driving force from the rotating shaft 131 to the second gear 142, and the driving member 143 can rotate synchronously with the second gear 142 in the same direction to transmit the driving force to the driven member 144.

As shown in FIG. 3A, FIG. 4A and FIG. 4B, the first lifting mechanism 145 contacts the first movable cover 113, and the second lifting mechanism 146 contacts the second movable cover 114. As shown in FIG. 3A to FIG. 3D, when the second body 120 rotates and unfolds relative to the first body 110, the shaft 131 can drive the driving member 143 to rotate through the first gear 141 and the second gear 142 (see FIG. 4A and FIG. 5A), and the driving member 143 can drive the follower 144 to rotate, so as to drive the first lifting mechanism 145 to rise through the follower 144 to drive the first movable cover 113 to rotate relative to the top 111, and simultaneously drive the second lifting mechanism 146 to descend to drive the second movable cover 114 to rotate relative to the bottom 112.

In contrast, when the second body 120 rotates and closes relative to the first body 110, the rotating shaft 131 can drive the driving member 143 to rotate through the first gear 141 and the second gear 142 (see Figures 4A and 5A), and the driving member 143 can drive the follower 144 to rotate, so as to drive the first lifting mechanism 145 to descend through the follower 144 to drive the first movable cover 113 to rotate relative to the top 111, and simultaneously drive the second lifting mechanism 146 to rise to drive the second movable cover 114 to rotate relative to the bottom 112.

That is, when the second body 120 rotates to open or close relative to the first body 110, the first lifting mechanism 145 and the second lifting mechanism 146 apply two opposite forces to the first movable cover 113 and the second movable cover 114 respectively.

As shown in FIG. 3A, FIG. 3B and FIG. 4B, the driving member 143 has a first protrusion 143a, and the driven member 144 has a first concave portion 144a located on the moving path of the first protrusion 143a. When the second body 120 is closed to the first body 110, the first protrusion 143a is separated from the first concave portion 144a. In the process of the second body 120 rotating and unfolding to the first angle A1 relative to the first body 110, the first protrusion 143a moves toward the first concave portion 144a. Before the first protrusion 143a is engaged with the first concave portion 144a, the driving member 143 stops driving the driven member 144 to rotate. Therefore, the follower 144 stops driving the first lifting mechanism 145 to rise, and also stops driving the second lifting mechanism 146 to descend, so that the first movable cover 113 and the second movable cover 114 are closed at the top 111 and the bottom 112 respectively, preventing the first movable cover 113 from hitting the second body 120.

As shown in FIG. 3B and FIG. 3C , when the second body 120 rotates and expands to a first angle A1 relative to the first body 110, the first protrusion 143a engages with the first recess 144a. When the second body 120 continues to rotate and expand to a second angle A2 greater than the first angle A1, the driving member 143 can drive the driven member 144 to rotate through the engagement of the first protrusion 143a and the first recess 144a. During the process of the second body 120 unfolding from the first angle A1 to the second angle A2, the follower 144 can drive the first lifting mechanism 145 to rise to drive the first movable cover 113 to rotate relative to the top 111, and simultaneously drive the second lifting mechanism 146 to descend to drive the second movable cover 114 to rotate relative to the bottom 112. Since the second body 120 has been rotated and unfolded relative to the first body 110 to a greater angle than the first angle A1, there is enough avoidance space to prevent the first movable cover 113 from hitting the second body 120.

As shown in FIG. 3C and FIG. 3D , once the second body 120 rotates and expands relative to the first body 110 to a greater than second angle A2, the first protrusion 143a separates from the first recess 144a, and the driving member 143 stops driving the follower 144 to rotate. Therefore, the follower 144 stops rotating and simultaneously stops driving the first lifting mechanism 145 to lift and the second lifting mechanism 146 to descend, so as to fix the first movable cover 113 and the second movable cover 114 in the unscrewed state.

As shown in FIG. 3A , the driving member 143 also has a second protrusion 143b, and the follower 144 also has a second recess 144b corresponding to the second protrusion 143b. When the second body 120 is closed to the first body 110, the second protrusion 143b is engaged with the second recess 144b to stop the follower 144 and prevent the follower 144 from being rotated accidentally.

As shown in Figures 3A to 3C, when the second body 120 rotates and expands to the first angle A1 relative to the first body 110, the second protrusion 143b separates from the second recess 144b. As the second body 120 continues to rotate and expand to the second angle A2 relative to the first body 110, the driving member 143 drives the follower 144 to rotate, and the rotation direction of the follower 144 is opposite to the rotation direction of the driving member 143, so that the distance between the second protrusion 143b and the second recess 144b gradually increases.

As shown in FIG. 3A to FIG. 3D , when the second body 120 rotates and closes relative to the first body 110 to a second angle A2, the first protrusion 143a is engaged with the first recess 144a. When the second body 120 rotates and closes relative to the first body 110 from the second angle A2 to the first angle A1, the driving member 143 drives the follower 144 to rotate through the engagement of the first protrusion 143a and the first recess 144a. At the same time, the follower 144 drives the first lifting mechanism 145 to descend to drive the first movable cover 113 to rotate relative to the top 111, and simultaneously drives the second lifting mechanism 146 to rise to drive the second movable cover 114 to rotate relative to the bottom 112. When the second body 120 is rotated and closed to the first angle A1 relative to the first body 110, the first movable cover 113 is closed at the top 111, and the second movable cover 114 is closed at the bottom 112.

When the second body 120 continues to rotate and close relative to the first body 110 and the angle between the two is less than the first angle A1, the first protrusion 143a separates from the first concave part 144a, and the driving member 143 stops driving the follower 144 to rotate. Therefore, the follower 144 stops rotating and synchronously stops driving the first lifting mechanism 145 to descend and the second lifting mechanism 146 to rise, so as to fix the first movable cover 113 and the second movable cover 114 in the closed state. Before the second body 120 is closed on the first body 110, the first movable cover 113 and the second movable cover 114 are already in the closed state, so the second body 120 can be prevented from hitting the first movable cover 113.

As shown in FIG. 3A, FIG. 4B and FIG. 5B, the first lifting mechanism 145 includes a first link 1451, a second link 1452 and a lifting member 1453, wherein one end of the first link 1451 is pivoted to the follower 144, and the other end of the first link 1451 is pivoted to one end of the second link 1452. In addition, the other end of the second link 1452 is pivoted to the first bracket 132, wherein the lifting member 1453 is slidably connected to the first link 1451 and fixedly connected to the first movable cover 113. For example, the first link 1451 is provided with a slide groove for the lifting member 1453 to slide thereon.
