Corresponding holes h are formed on the bottom cover 13, and the elastic element S is sandwiched between the lower case 12 and the bottom cover 13 (Fig. 7).

Specifically, the aforementioned bottom cover 13 is composed of a rectangular receiving structure 130 and a rectangular frame 131, wherein the aforementioned receiving structure 130 passes through the opening 120 in the center of the lower case 12 (Figs. 5 and 7). , the aforementioned frame 131 surrounds the aforementioned accommodating structure 130, and the aforementioned perforation h is formed on the frame 131.

Please refer to Figure 8 again. Figure 8 shows a schematic diagram in which the airflow enters from the left and right sides of the lower housing 12 and exits from the top side of the lower housing 12 .

As shown in the direction of the arrow in Figure 8, after the body 10 of the electronic device 100 is assembled, the fans F on both sides of the circuit board B1 can be used to pass the external air through the left and right sides of the lower case 12. The air inside the main body 10 is sucked into the main body 10 from the side, and then the air inside the main body 10 is discharged from the top side of the lower case 12, so as to achieve the purpose of dissipating and cooling the electronic components inside the main body 10.

In one embodiment, the aforementioned fan F can also suck outside air into the main body 10 through the top side of the lower casing 12, and then discharge the air inside the main body 10 from the left and right sides of the lower casing 12. The same is true for The purpose of dissipating and cooling the electronic components inside the body 10 can be achieved, and is not limited to those disclosed in the embodiments of the present invention.

Next, please refer to Figures 9 and 10 together. Figure 9 shows a partial cross-sectional view of the main body 10 of the electronic device 100, and Figure 10 shows a partial enlarged view of the main body 10 in Figure 9.

As can be seen from Figures 9 and 10, for example, when the electronic device 100 is turned off or does not need to enhance the heat dissipation performance, the air pump 50 inside the body 10 has not yet or does not need to inflate the airbag 40. At this time, the electronic device The bottom cover 13 below the main body 10 of 100 is located at a first height relative to the lower case 12, and the foot pads 14 protrude from the bottom sides of the bottom cover 13 and the lower case 12 to contact the desktop.

It should be noted that since an elastic element S (such as a compression spring) is provided between the lower case 12 and the bottom cover 13 , an elastic force can be generated through the elastic element S so that the bottom cover 13 can maintain its position relative to the lower case 12 At the aforementioned first height (as shown in Figures 9 and 10).

Please refer to Figures 11 and 12 together. Figure 11 shows a schematic diagram when the bottom cover 13 sinks to a second height relative to the lower case 12 from the first height shown in Figures 9 and 10. Figure 12 This shows a partial enlarged view of the main body 10 in Figure 11 .

As can be seen from Figures 11 and 12, when the electronic device 100 is powered on or needs to enhance the heat dissipation performance due to excessive temperature, the air pump 50 inside the body 10 can be activated, and the air pump 50 can pass through the tube. Road C inflates the air bag 40. At this time, the air bag 40 will expand and push the bottom cover 13 downward, so that the bottom cover 13 can move along the -Z axis relative to the lower housing 12 from the first height shown in Figures 9 and 10. Settled to a second height (as shown in Figures 11 and 12).

In this state, the accommodation structure 130 of the bottom cover 13 will protrude from the bottom side of the lower case 12 in the -Z-axis direction, and the internal space 101 of the body 10 (formed between the upper case 11 and the lower case 12 ) increases, thereby helping to increase the air intake volume of the fan F, and greatly improving the heat dissipation performance of the electronic device 100 .

It should be noted that when the bottom cover 13 sinks from the first height shown in Figures 9 and 10 to the second height along the -Z axis relative to the lower housing 12 (as shown in Figures 11 and 12), The elastic element S located between the lower case 12 and the bottom cover 13 will be further compressed.

On the other hand, during the process of the electronic device 100 switching from the aforementioned second height (for example, in the powered-on state) to the first height (for example, in the powered-off state), the airbag 40 can be aligned through the air pump 50 and the pipeline C. deflate, and at the same time, the elastic force generated by the elastic element S itself can be used to push the bottom cover 13 upward, so that the bottom cover 13 automatically returns to the first height as shown in Figures 9 and 10, thereby greatly reducing the volume of the body 10, and The electronic device 100 can be conveniently stored by the user.

To sum up, the present invention provides an electronic device 100. When the electronic device 100 is in the shutdown mode, the bottom cover 13 is at the first height relative to the lower case 12. When the electronic device 100 is switched to the powered-on state or needs to be strengthened, When the heat dissipation efficiency is high, the air pump 50 inside the body 10 can be activated to inflate the air bag 40. At this time, the air bag 40 will expand and push the bottom cover 13 downward, so that the bottom cover 13 moves from the position shown in Figures 9 and 10. The first height sinks to the second height along the -Z axis direction relative to the lower case 12 (as shown in FIGS. 11 and 12 ), so as to greatly improve the heat dissipation performance of the electronic device 100 .

In addition, during the switching process of the present invention, the user does not need to change the habit of using the keyboard, and there is no discomfort caused by the ups and downs of the electronic device 100 during switching.
