Description

Technical Field

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

[0002] Due to their portability, multitasking capabilities, and excellent computing performance, laptops have become indispensable tools for modern people. Specifically, a laptop consists of a host computer and a monitor that are pivotally connected to each other. Since the monitor can only rotate relative to the host computer around a single axis, the viewing angle and operating angle are relatively limited. Therefore, a design has been proposed where the monitor is pivotally connected to the host computer via a stand, allowing users to flexibly adjust the monitor's viewing angle, operating angle, or operating height.

[0003] Generally, the pivot joint between the monitor and the stand is integrated with a single-axis hinge, allowing the monitor to rotate relative to the stand. However, the range of rotation angles of the monitor is too small, resulting in a lack of operational flexibility. Summary of the Invention

[0004] This invention relates to a portable electronic device that helps improve operational flexibility.

[0005] According to an embodiment of the present invention, a portable electronic device includes a first body, a second body, a bracket, and a hinge structure. The bracket has a first pivot portion and a second pivot portion relative to the first pivot portion, wherein the first pivot portion is pivotally connected to the first body, and the second body is pivotally connected to the second pivot portion. The hinge structure includes a first fixed frame fixed to the second body, a second fixed frame fixed to the second pivot portion of the bracket, a first movable seat, a first rotating shaft fixed to the first fixed frame and pivotally connected to the first movable seat, a second movable seat, a second rotating shaft fixed to the first movable seat and pivotally connected to the second movable seat, and a sliding shaft fixed to the second movable seat and slidably connected to the second fixed frame.

[0006] Based on the above, in the portable electronic device of the present invention, the second body is pivotally connected to the bracket via a dual-axis hinge structure. Therefore, the second body can be rotated relative to the bracket in sequence via two rotating shafts to increase the range of rotation angles and thus improve operational flexibility. On the other hand, when the second body is rotated relative to the bracket via one of the two rotating shafts, the second body can slide relative to the bracket to improve the smoothness of rotation and prevent the second body from colliding with the bracket during rotation.

[0013] 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.

[0014] Figure 1A This is a schematic diagram of a portable electronic device in a first state according to an embodiment of the present invention. Figure 1B yes Figure 1A A schematic diagram of the hinge structure. Please refer to it. Figure 1A and Figure 1B In this embodiment, the portable electronic device 100 may be a laptop computer, and includes a first body 110, a second body 120, a stand 130, and a hinge structure 140. The first body 110 may be a host computer with functions such as logic operation and data access, and the second body 120 may be a display with image display function. The second body 120 is pivotally connected to the first body 110 via the stand 130, and can rotate relative to the first body 110 about two parallel axes in space, thus helping to improve the flexibility of operation.

[0015] In detail, the bracket 130 has a first pivot portion 131 and a second pivot portion 132 relative to the first pivot portion 131, wherein the first pivot portion 131 is pivotally connected to the first body 110, and the second body 120 is pivotally connected to the second pivot portion 132. On the other hand, the hinge structure 140 may be a dual-axis hinge structure, and the second body 120 is pivotally connected to the bracket 130 via the hinge structure 140.

[0016] In this embodiment, the hinge structure 140 includes a first fixed frame 141, a second fixed frame 142, a first movable seat 143, a first rotating shaft 144, a second movable seat 145, a second rotating shaft 146, and a sliding shaft 147. The first fixed frame 141 is fixedly connected to the second body 120, and the second fixed frame 142 is fixedly connected to the second pivot portion 132 of the bracket 130. The first movable seat 143 and the second movable seat 145 are disposed between the first fixed frame 141 and the second fixed frame 142, wherein the first fixed frame 141 is pivotally connected to the first movable seat 143, and the first movable seat 143 is pivotally connected to the second movable seat 145. Furthermore, the second movable seat 145 is slidably connected to the second fixed frame 142.

[0017] In detail, the first rotating shaft 144 is fixed to the first fixed frame 141 and pivotally connected to the first movable seat 143. The second rotating shaft 146 is fixed to the first movable seat 143 and pivotally connected to the second movable seat 145. That is, the first rotating shaft 144 and the second rotating shaft 146 are located on opposite sides of the first movable seat 143. The sliding shaft 147 is fixed to the second movable seat 145 or is a convex shaft on the second movable seat 145, and the second movable seat 145 is slidably connected to the second fixed frame 142 via the sliding shaft 147. On the other hand, the second rotating shaft 146 and the sliding shaft 147 are located at opposite ends of the second movable seat 145, and the second rotating shaft 146 is located between the first rotating shaft 144 and the sliding shaft 147.

[0018] Figure 2A This is a schematic diagram of a portable electronic device switching to a second state according to an embodiment of the present invention. Figure 2B yes Figure 2A A schematic diagram of the hinge structure. Figure 3A This is a schematic diagram of a portable electronic device transitioning to a third state according to an embodiment of the present invention. Figure 3B yes Figure 3A A schematic diagram of the hinge structure. (See diagram below.) Figures 1A to 2B As shown, in this embodiment, the torque of the first rotating shaft 144 is greater than the torque of the second rotating shaft 146. Furthermore, when the first movable seat 143 flips relative to the second movable seat 145 via the second rotating shaft 146, a first torque is generated between the second rotating shaft 146 and the second movable seat 145. On the other hand, when the first fixed frame 141 flips relative to the first movable seat 143 via the first rotating shaft 144, a second torque greater than the first torque is generated between the first rotating shaft 144 and the first movable seat 143.

[0019] Because the torque of the first rotating shaft 144 is greater than the torque of the second rotating shaft 146, during the rotation of the second body 120 relative to the support 130, the second body 120 first rotates relative to the support 130 by a first angle (e.g., 90 degrees) via the second rotating shaft 146. After the second body 120 rotates relative to the support 130 by the second rotating shaft 146 by the first angle (e.g., 90 degrees), the degree of freedom of rotation of the second rotating shaft 146 relative to the second movable seat 145 is restricted. That is, the second rotating shaft 146 cannot rotate relative to the second movable seat 145 at this time. Then, the second body 120 rotates relative to the support 130 by a second angle (e.g., 90 degrees) via the first rotating shaft 144, as... Figures 2A to 3B As shown. Furthermore, the second unit 120 can rotate from 0 degrees to 180 degrees, and the maximum rotation angle is the sum of the first angle (e.g., 90 degrees) and the second angle (e.g., 90 degrees).

[0020] Continuing from the above, the second body 120 can be rotated relative to the bracket 130 in sequence via the second pivot 146 and the first pivot 144 to increase the range of rotation angles and thus improve operational flexibility. On the other hand, when the second body 120 is rotated relative to the bracket 130 via the second pivot 146, the second body 120 can slide relative to the bracket 130 to improve the smoothness of the rotation of the second body 120 and prevent the second body 120 from colliding with the bracket 130 during rotation.

[0021] like Figure 1B , Figure 2B and Figure 3B As shown, the first movable seat 143 has a sliding protrusion 1431 disposed around the second rotating shaft 146, and the sliding protrusion 1431 is slidably attached to the second fixed frame 142. More specifically, the sliding protrusion 1431 is adapted to slide along the sliding direction D1 on the second fixed frame 142, while the sliding shaft 147 is adapted to slide along the sliding direction D2 on the second fixed frame 142, which is not parallel to the sliding direction D1.

[0022] like Figures 1A to 2B As shown, when the second body 120 flips relative to the bracket 130, because the torque of the first rotating shaft 144 is greater than the torque of the second rotating shaft 146, the first fixed frame 141 and the first movable seat 143 first flip relative to the second movable seat 145 and the second fixed frame 142 via the second rotating shaft 146. Simultaneously, the sliding protrusion 1431 slides along the sliding direction D1 on the second fixed frame 142, and drives the second movable seat 145 to slide relative to the second fixed frame 142 along the sliding direction D2, thereby driving the second body 120 to slide relative to the bracket 130 via the first movable seat 143 and the first fixed frame 141. Specifically, the sliding shaft 147 can be used to determine the sliding direction of the second movable seat 145, and the sliding protrusion 1431 and the sliding shaft 147 slide synchronously.

[0023] Continuing from the above, when the sliding shaft 147 can no longer slide, the first fixed frame 141 and the first movable seat 143 have been rotated by a first angle (e.g., 90 degrees) relative to the second movable seat 145 and the second fixed frame 142. Similarly, the second body 120 has been rotated by a first angle (e.g., 90 degrees) relative to the bracket 130.

[0024] When the sliding shaft 147 can no longer slide, the first movable seat 143 and the second movable seat 145 remain stationary, the second body 120 continues to rotate relative to the bracket 130, and the first fixed frame 141 rotates relative to the first movable seat 143 by a second angle (e.g., 90 degrees) via the first rotating shaft 144. Figures 2A to 3B As shown. At this time, the second body 120 is rotated at an angle of 180 degrees relative to the support 130, which is the sum of the first angle (e.g., 90 degrees) and the second angle (e.g., 90 degrees).

[0025] like Figure 1B , Figure 2B and Figure 3B As shown, in this embodiment, the second fixing frame 142 has a sliding groove 1421 and a guide groove 1422 located on one side of the sliding groove 1421, wherein the sliding shaft 147 is slidably disposed within the sliding groove 1421, and the sliding protrusion 1431 is slidably disposed within the guide groove 1422. Specifically, the sliding groove 1421 and the guide groove 1422 are used to determine the sliding direction of the sliding shaft 147 and the sliding protrusion 1431, respectively, and the sliding groove 1421 and the guide groove 1422 are not parallel to each other. On the other hand, the sliding groove 1421 has a first stroke end point 1423 and a second stroke end point 1424, wherein the second stroke end point 1424 is located between the second rotating shaft 146 and the first stroke end point 1423, and is also located between the guide groove 1422 and the first stroke end point 1423. That is, the sliding groove 1421 extends towards the second rotating shaft 146 and the guide groove 1422.

[0026] When the first fixed frame 141 and the first movable seat 143 are flipped relative to the second movable seat 145 and the second fixed frame 142 via the second rotating shaft 146, the sliding protrusion 1431 slides on the second fixed frame 142 along the sliding direction D1, and drives the sliding shaft 147 to slide on the second fixed frame 142 along the sliding direction D2, so that the sliding shaft 147 slides from the first stroke end point 1423 to the second stroke end point 1424 or from the second stroke end point 1424 to the first stroke end point 1423 in the sliding groove 1421.

[0027] Once the sliding shaft 147 slides to the first stroke end point 1423 and cannot continue to slide away from the second stroke end point 1424, or slides to the second stroke end point 1424 and cannot continue to slide away from the first stroke end point 1423, the first movable seat 143 and the second movable seat 145 remain stationary, and the first fixed frame 141 can be flipped relative to the first movable seat 143 by the first rotating shaft 144.

[0028] In summary, in the portable electronic device of the present invention, the second body is pivotally connected to the bracket via a dual-axis hinge structure, and the torque of the first rotating shaft is greater than that of the second rotating shaft. Therefore, the second body can be flipped relative to the bracket sequentially via the second rotating shaft and the first rotating shaft to increase the range of flipping angles and thus improve operational flexibility. On the other hand, when the second body is flipped relative to the bracket via the second rotating shaft, the second body can slide relative to the bracket to improve the smoothness of the flipping and prevent the second body from colliding with the bracket during flipping.
