Since the rotation axis of the second body falls on the flexible screen, when the second body rotates and opens relative to the first body, the flexible screen is not easily damaged by the first body and the second body or is damaged by the hinge. Mechanism clamping damage not only helps to increase the service life, but also helps to improve the smoothness of the rotation, opening and closing of the second body relative to the first body.

In order to make the above-mentioned features and advantages of the present invention more obvious and easy to understand, embodiments are given below and described in detail with reference to the accompanying drawings.

1A and 1B are partial cross-sectional views of a portable electronic device in two different states according to an example of the present invention. FIG. 1C is a schematic diagram of a hinge mechanism according to an example of the present invention. Please refer to FIGS. 1A and 1B . In this embodiment, the portable electronic device 100 may be a notebook computer and includes a first body 110 , a second body 120 , a hinge mechanism 130 and a flexible screen 140 . The second body 120 is connected to the first body 110 through the hinge mechanism 130 to rotate and open relative to the first body 110, for example, between the closed state shown in FIG. 1A and the expanded state shown in FIG. 1B.

In detail, the flexible screen 140 extends from the second body 120 to the first body 110 and has a first display part 141, a second display part 142 and a flexible display part 143. The first display part 141 is fixed on the first body 110 , and the second display part 142 is fixed on the second body 120 . For example, the second display part 142 is larger in size than the first display part 141 .

In addition, the flexible display part 143 is located between the second body 120 and the first body 110 and corresponds to the flexible display part 143 of the hinge mechanism 130 . In other words, the flexible display part 143 is located between the first display part 141 and the second display part 142 , and the second display part 142 is connected to the first display part 141 through the flexible display part 143 . As the second body 120 rotates, opens and closes relative to the first body 110, the flexible display part 143 undergoes corresponding deformation, for example, being pushed by the second body 120 and the first body 110 to be in the folded state shown in FIG. 1A , or is stretched by the second body 120 and the first body 110 to be in the expanded state shown in FIG. 1B .

In other words, the sliding part 132a of the second bracket 132 is indirectly slidably connected to the slide rail 131a of the first bracket 131 through the sliding member 133.

When the second body 120 rotates and opens relative to the first body 110 , the sliding part 132 a of the second bracket 132 slides around the axis 101 on the flexible display part 143 relative to the sliding member 133 , and the sliding member 133 The slide rail 131a slides around the axis 101 relative to the first bracket 131 . That is to say, the second body 120 rotates around the axis 101 to open and close relative to the first body 110 . Since the rotation reference of the second body 120 , the sliding reference of the second bracket 132 and the sliding reference of the slider 133 are all the axis 101 falling on the flexible display part 143 , when the second body 120 rotates relative to the first body 110 During the opening and closing process, the flexible display part 143 is not easily damaged by the first body 110 and the second body 120 or by the hinge mechanism 130 , which not only helps to improve the service life, but also helps to improve the relative position of the second body 120 . Smoothness of rotation, opening and closing of the first body 110.

As shown in FIGS. 1A to 1C , in this embodiment, the sliding portion 132a, the sliding member 133 and the sliding rail 131a are all arc-shaped structures, and preferably are arc-shaped structures. That is to say, the sliding part 132a, the sliding part 133 and the sliding rail 131a may be an arc-shaped sliding part, an arc-shaped sliding part and an arc-shaped slide rail respectively. As shown in FIG. 1A and FIG. 1B , the concave arcs of the sliding part 132 a , the sliding part 133 and the sliding rail 131 a all face the flexible display part 143 of the flexible screen 140 , wherein the sliding parts 132 a , the sliding part 133 and the sliding rail 131 a The centers of curvature all fall on the flexible display part 143 of the flexible screen 140, and the centers of curvature of the sliding part 132a, the sliding member 133 and the slide rail 131a are the axis 101.

As shown in FIGS. 1A to 1C , the first bracket 131 further includes a first fixing part 131b fixed to the first body 110 , wherein the slide rail 131a is connected to the first fixing part 131b, and the first fixing part 131b has a slide groove 131c. The second bracket 132 also includes a second fixing part 132b fixed to the second body 120, and the sliding part 132a is connected to the second fixing part 132b. In addition, the connecting rod 134 has a first end 134a and a second end 134b opposite to the first end 134a, wherein the first end 134a is pivotally connected to the sliding part 132a, and the second end 134b is slidingly connected to the sliding part of the first fixing part 131b. Slot 131c.

As shown in Figures 1A and 1B, the chute 131c is a linear chute. When the second body 120 rotates and opens relative to the first body 110, the second bracket 132 drives the connecting rod 134, so that the second The two ends 134b slide between the two stroke end points in the slide groove 131c. In the closed state shown in Figure 1A, the second end 134b of the connecting rod 134 is located at a stroke end point adjacent to the axis 101. In contrast, in the expanded state shown in Figure 1B, the second end 134b of the connecting rod 134 is The end 134b is located at another stroke end point away from the axis 101 . Furthermore, the length of the chute 131c can be used to determine the maximum expansion angle of the second body 120, such as 150 degrees.

2A and 2B are partial cross-sectional views of a portable electronic device in two different states according to another example of the present invention. Figure 2C is a schematic diagram of a hinge mechanism according to another example of the present invention. Please refer to FIGS. 2A to 2C . The portable electronic device 100A of this embodiment has the same or similar design principles as the portable electronic device 100 of the previous embodiment. The main difference between the two lies in the design of the hinge mechanism. . In the hinge mechanism 1301 of this embodiment, the first fixing part 131b does not have a sliding groove, and the second fixing part 132b has a sliding groove 132c. The first end 134a of the connecting rod 134 is pivotally connected to the first fixing part 131b, and the second end 134b is slidably connected to the slide groove 132c of the second fixing part 132b.

To sum up, in the portable electronic device of the present invention, the second body can rotate and open and close relative to the first body through the hinge mechanism to drive the flexible screen to produce corresponding deformations, such as in the folded state and the unfolded state. Convert between. Since the rotation axis of the second body falls on the flexible screen, when the second body rotates and opens relative to the first body, the flexible screen is not easily damaged by the first body and the second body or is damaged by the hinge. Mechanism clamping damage not only helps to increase the service life, but also helps to improve the smoothness of the rotation, opening and closing of the second body relative to the first body.
