For convenience of explanation and illustration, the first body 201 is omitted. Referring to FIG. 5A and FIG. 5B, the electronic device 200C of the present embodiment is substantially the same as the electronic device 200A of the third embodiment. Further, the electronic device 200C is configured to drive the second casing 220b to rotate relative to the first casing 210b. The mechanism is the same as that of the electronic device 200A of the third embodiment, that is, the switching mechanism of the heat dissipation opening 203 of the electronic device 200C is the same as that of the electronic device 200A of the third embodiment, and the main difference between the two is: in this embodiment The first link 244 can further drive the first casing 210b to lift. Further, the first link 244 further has a guiding portion 244c between the driven end 244a and the pushing end 244b, wherein the second casing A second link 280 is disposed between the 220b and the first casing 210b, and the second link 280 is slidably coupled to the guiding portion 244c.

The second link 280 has an opposite sliding end 281 and a pivoting end 282. The first housing 210b includes a frame 212 of the adapter frame 211 and the sliding adapter 211, and the frame 212 is used to carry the display panel, for example. . The adapter frame 211 is located between the second casing 220b and the frame 212, wherein the guiding portion 244c is slidably connected to the sliding end 281, and the pivoting end 282 is pivotally connected to the adapter frame 211. For example, the guiding portion 244c and the sliding end 281 can be a cooperation of the guide pin and the sliding slot. During the rotation of the first link 244, the second link 280 is driven by the first link 244 to pull the adapter frame 211 through the pivoting end 282, and the adapter frame 211 and the frame 212 are moved to cause structural interference. The frame 212 is raised. The pushing of the frame 212 can form a heat dissipation gap to improve the convection effect and heat dissipation efficiency.

Further, the adapter frame 211 is provided with at least one guiding member 211a, and the frame 212 has at least one guiding slot 212a. The guiding member 211a is slidably disposed on the guiding groove 212a. When the adapter frame 211 is driven by the second connecting rod 280, the guiding member 211a slides in the guiding groove 212a, and the pushing or lowering of the frame 212 is guided by The geometric design of the slot 212a is caused. Further, the guiding groove 212a has an opposite first positioning section 212b and a second positioning section 212c. As shown in FIG. 5A, the guiding member 211a is located at the first positioning section 212b, and the frame 212 is not lifted. There is a step D between the first positioning segment 212b and the second positioning segment 212c, and the first positioning segment 212b and the second positioning segment 212c are connected through the slope segment. Therefore, the guiding member 211a is inclined from the first positioning segment 212b via the slope. During the movement of the segment to the second positioning segment 212c, the frame 212 is gradually raised until the guiding member 211a moves into the second positioning segment 212c, and the lifting action of the frame 212 is stopped. Conversely, during the movement of the guiding member 211a from the second positioning segment 212c to the first positioning segment 212b via the ramp segment, the frame 212 is gradually lowered until the guiding member 211a moves into the first positioning segment 212b, and the frame 212 is lowered. stop.

In summary, the electronic device created by the present invention adopts a movable heat dissipation design. Further, when the electronic device is in a shutdown or sleep state, the electronic device does not have a heat dissipation hole, so that the appearance integrity can be preserved and prevented. Foreign matter or moisture from the outside enters the inside of the electronic device. When the electronic device is in operation, the two housings are partially separated to define a heat dissipation opening to communicate the outside and the inside of the electronic device, so that the heat generated by the electronic component is quickly generated from the interior of the electronic device via the heat dissipation opening. Discharge to the outside world.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the novel creation, and any person skilled in the art can make some changes without departing from the spirit and scope of the novel creation. Retouching, the scope of protection of this new creation is subject to the definition of the scope of the patent application attached.
