On the other hand, with the improvement of the level of technology, various types of portable electronic devices are not moving toward a trend of lightness and thinness, and because of the characteristics and advantages that are easy to carry around, the public generally accepts and uses them in daily life. In the case of a slide type mobile phone and a slide type tablet, the upper and lower bodies are stacked and relatively slid to exhibit different operating modes such as opening and closing. Stacking the upper and lower bodies helps to reduce the overall volume, and can expand the upper and lower bodies in a specific operating mode. For example, in addition to the relative sliding of the upper and lower bodies of some slide-type mobile phones, the upper body can be tilted to the lower body to facilitate the user to view the display screen of the upper body.

When the user pushes the upper body to slide relative to the lower body, if the force is unevenly applied, the sliding speeds on both sides of the upper body may be inconsistent, causing the upper body and the lower body to yaw and cannot smoothly slide. In some designs, the gears and the racks are used to drive the two sides of the upper body to operate synchronously to solve the yaw problem. However, the design of the gears and the racks is complicated and the manufacturing cost and assembly difficulty are easily increased.

The material of the friction roller 124, the friction roller 134 and the friction roller 144 of the present embodiment is, for example, a rubber, a thermoplastic polyurethane (TPU) or a thermoplastic rubber (TPR) having a high friction coefficient. The material is to prevent relative sliding between the first body 112 (or the second body 114) when the friction roller rolls. The rubber, the thermoplastic polyurethane or the thermoplastic rubber is an elastic material, so that the friction roller 134 can be compressed by the positioning convex portion 114a or the positioning convex portion 114b to firmly fix the relative positions of the first body 112 and the second body 114. In addition, since the material of the friction roller 124 is an elastic material as described above, when the second body 114 is closed from the state of FIG. 1C to the state shown in FIG. 1B, the first body 112 and the first body 112 can be absorbed by the buffering of the friction roller 124.

The second body 114 can be inclined to the first body 112 as shown in FIGS. 1C and 8 by the rotation of the rotating member 112b relative to the base 112a. When the portable electronic device 100 is in the state shown in FIG. 8, the positioning of the friction roller 134 by the positioning convex portion 114b can fix the position of the second body 114, thereby preventing the second body 114 from undesirably sliding.

9 is a partial cross-sectional view of the portable electronic device of FIG. 1 taken along line III-III. Referring to FIG. 9 , in the embodiment, the rotating member 112 b has a recess 112 d , and the friction roller 134 is located in the recess 112 d , thereby saving the configuration space and avoiding the increase of the portable electronic device 100 due to the provision of the friction roller 134 . thickness. In addition, in this embodiment, the second body 114 has a slide rail. 114c, the rotating member 112b is slidably disposed on the sliding rail 114c, so that the first body 112 and the second body 114 are relatively slid by the movement of the rotating member 112b along the sliding rail 114c. In other embodiments, the first body 112 and the second body 114 can be slid by each other by other forms of structure, and the present invention does not limit this.

In summary, the two friction rollers of the present invention are respectively fixed to the two ends of the shaft, so that the two friction rollers are adapted to roll synchronously. When the second body slides relative to the first body, the two friction rollers contact the first body or the second body and roll synchronously to ensure that the first body and the second body have the same relative sliding speed at the positions of the two friction rollers, and The first body and the second body can be prevented from being yawed, so that the first body and the second body can smoothly slide relative to each other. Since the roller module is supported between the first body and the second body, the first body and the second body can maintain a proper gap to avoid scratches when the first body and the second body slide relative to each other. The material of the friction roller can be an elastic material, so that the friction roller can be compressed by the positioning convex portion of the main body to firmly fix the relative positions of the first body and the second body. In addition, when the second body is closed to the first body, the impact energy of the first body and the second body can be absorbed by the buffer of the elastic material friction roller to avoid the portable electronic device due to the first body and the first body The damage caused by the collision of the two bodies with respect to the closed body.
