The present invention relates to a device, and in particular to an electronic device.

With the booming e-sports industry, gaming laptops need to be lightweight and portable while pursuing high performance.

However, gaming laptops require high-performance graphics processors because of their high screen display capabilities. At the same time, gaming laptops cannot effectively reduce the thickness of the entire machine due to performance requirements.

Furthermore, the fan plays a key role in affecting the heat dissipation performance of gaming laptops. However, because the fan and keyboard are usually stacked, the thickness of the fan is limited by the thickness of the entire machine, and the heat dissipation effect cannot be further improved by changing the thickness of the fan.

In addition, in gaming laptops, because the fan and keyboard are stacked together, it is usually difficult to achieve optimal efficiency in introducing cool air from outside the laptop into the laptop.

The present invention provides an electronic device which is convenient to use.

FIG1A is a schematic diagram of an electronic device according to a first embodiment of the present invention, FIG1B is a perspective diagram of the electronic device from another viewing angle, and FIG1C is an exploded schematic diagram of the electronic device of FIG1A. Referring to FIG1A, FIG1B and FIG1C simultaneously, the electronic device 100 of the present embodiment is a notebook computer, which includes a first body 110, a second body 120 and a fan module (not shown).

The first body 110 is a logic device, which includes a housing 112, a first input module 114, and a second input module 116, wherein the first input module 114 and the second input module 116 are both disposed in the housing 112, and the thickness of the first input module 114 is greater than the thickness of the second input module 116. In this embodiment, the first input module 114 is a keyboard, and the second input module 116 is a touch panel or a display for displaying numbers.

The second body 120 is a display screen, which is pivotally connected to the first body 110 and links the second input module 116. In other words, when the second body 120 is opened or closed relative to the first body 110, the second input module 116 will be driven by the second body 120 to change state.

FIG2 is a schematic diagram of the thickness of the input module and the fan module. In FIG2, in order to clearly illustrate the relationship between the thickness of the input module and the fan module, the actual situation that the second input module 116 is lifted relative to the housing 112 when the first body 110 and the second body 120 are opened relative to each other is not shown. Those skilled in the art should know that in actual situations, when the first body 110 and the second body 120 are opened relative to each other, the second input module 116 is lifted relative to the housing 112.

Please refer to FIG. 1B, FIG. 1C and FIG. 2 simultaneously. The fan module (not shown) includes a first fan 130 and a second fan 140 both disposed in the housing 112. The thickness of the first fan 130 is less than that of the second fan 140. The first fan 130 is disposed corresponding to the first input module 114, and the second fan 140 is disposed corresponding to the second input module 116. The corresponding arrangement referred to here means that at least a portion of the first fan 130 is located within the orthographic projection range of the first input module 114, and at least a portion of the second fan 140 is located within the orthographic projection range of the second input module 116.

In this embodiment, the linkage between the second input module 116 and the second body 120 is achieved by the arrangement of a slide rail and a pivot. Specifically, the housing 112 has a slide rail 112a, and one end of the second input module 116 is movably arranged on the slide rail 112a, and the other end of the second input module 116 is pivotally connected to the second body 120. Thus, as the second body 120 is opened or closed relative to the first body 110, the second input module 116 rotates relative to the second body 120 with one end pivoted to the second body 120 as the rotation axis, and as the second body 120 is opened or closed relative to the first body 110, one end of the second input module 116 disposed on the slide rail 112a moves in the slide rail 112a.

The first body 110 has a first air inlet 110a and a first air outlet 110b, wherein the first air inlet 110a is located at the bottom of the housing 112, and the first air outlet 110b is located at a side where the first body 110 and the second body 120 are connected. The first air inlet 110a and the first air outlet 110b are the main air inlet/outlet of the electronic device 100.

The electronic device 100 further includes a first heating element 117 and a second heating element 118 disposed in the housing 112, wherein the first heating element 117 is a GPU or a CPU and is disposed close to the second fan 140, and the thermal power of the second heating element 118 is less than the thermal power of the first heating element 117, and the second heating element 118 is disposed relatively farther from the second fan 140 than the first heating element 117.

FIG. 3A is a schematic diagram of an electronic device when it is closed, FIG. 3B is a schematic diagram of an electronic device when it is opened 90 degrees, and FIG. 3C is a schematic diagram of an electronic device when it is opened 135 degrees.

Please refer to FIG. 2 and FIG. 3A , when the electronic device 100 is closed, the first body 110 and the second body 120 are attached to each other, and the top surface of the second input module 116 can be flush with or lower than the top surface of the first input module 114.

By the way, by designing that the thickness L1 of the first input module 114 is greater than the thickness L2 of the second input module 116 and the thickness L3 of the first fan 130 is less than the thickness L4 of the second fan 140, the total thickness L5 of the first input module 114 and the first fan 130 can be roughly equal to or equal to the total thickness L6 of the second input module 116 and the second fan 140.

1A , 3B and 3C , the second body 120 is opened relative to the first body 110 , and as the rotation angle of the second body 120 relative to the first body 110 increases, the second input module 116 is driven by the second body 120 to change its state relative to the housing 112 .

Specifically, the second input module 116 rotates relative to the second body 120 with one end pivoted to the second body 120 as the rotation axis, and as the opening angle of the second body 120 relative to the first body 110 gradually increases, the second input module 116 is set at one end of the slide rail 112a and moves from one end of the slide rail 112a toward the other end.

When the user adjusts the second body 120 to a suitable viewing angle, the first body 110 and the second body 120 are kept at a fixed angle by the torque provided by the hinge device used to hinge the first body 110 and the second body 120 together; therefore, the position of one end of the second input module 116 disposed on the slide rail 112a is also fixed in the slide rail 112a. At this time, the state of the second input module 116 is changed and the tilted position is located between the housing 112 and the second body 120.

For the user, since the state of the second input module 116 is changed to be higher than the first input module 114 and tilted in front of the user, the user can easily see and use the second input module 116, which is convenient to use.

FIG. 4A is a schematic diagram showing that the electronic device 100 has an auxiliary air inlet/outlet after the state of the second input module is changed. FIG. 4B is a schematic diagram showing FIG. 4A from another angle. Please refer to FIG. 4A and FIG. 4B simultaneously. After the second input module 116 changes its state relative to the housing 112, since the second input module 116 is tilted toward the housing 112, an opening is formed between the second input module 116 and the housing 112, and the opening becomes a second air inlet 122 for further improving the heat dissipation effect of the electronic device 100.

As can be seen from FIG. 4A and FIG. 4B , when the electronic device 100 is opened for use, in addition to the first air inlet 110a located at the bottom of the housing 112 being able to provide airflow to the first fan 130 and the second fan 140 and dissipate the hot air inside the housing 112 from the first air outlet 110b, the opening formed between the housing 112, the second input module 116 inclined to the housing 112, and the second body 120 because the second body 120 is opened relative to the first body 110 can serve as the second air inlet 122. Through the operation of the second fan 140, the air outside the electronic device 100 can enter the housing 112 from the second air inlet 122 through the suction of the second fan 140. Correspondingly, a second air outlet 124 can be provided on the side of the casing 112 adjacent to the second air inlet 122, wherein the side provided with the second air outlet 124 is different from the side provided with the first air outlet 110b, and similarly, through the operation of the second fan 140, the heat accumulated in the casing 112 can be dissipated from the second air outlet 124.

Compared to the conventional electronic device, the electronic device 100 of the present embodiment further forms a second air inlet 122 and a second air outlet 124 near the second input module 116 after the second body 120 is opened relative to the first body 110, thereby being able to further enhance the heat dissipation effect of the first heating element 117 (shown in FIG. 1A ) disposed adjacent to the second fan 140.

Incidentally, a baffle or a soft material spacer may be used to seal the opening formed on the side of the second input module 116 adjacent to the first input module 114 to prevent hot air from escaping from the side and causing discomfort to the user who is using the first input module 114.

Second Embodiment

FIG5A is a schematic diagram of the electronic device of the second embodiment of the present invention when it is closed. Referring to FIG5A , this embodiment is substantially the same as the first embodiment described above, but the difference lies in the linkage method between the second input module 116′ and the second body 120.

Specifically, the electronic device 100' further includes a first gear 132, a second gear 134 and a gear 136, wherein the first gear 132 is disposed in the second body 120, and the second gear 134 and the gear 136 are disposed in the housing 112, and the second gear 134 is engaged between the first gear 132 and the gear 136. The gear 136 has a plurality of protrusions 136a, and the second input module 116 has a plurality of tracks 116a, and the protrusions 136a are correspondingly disposed in the tracks 116a.

FIG5B is a schematic diagram of the electronic device of FIG5A when it is opened, and FIG6 is a three-dimensional schematic diagram of FIG5B. Please refer to FIG5A, FIG5B and FIG6 together, when the user opens the electronic device 100, the first body 110 and the second body 120 are changed from the closed state to the open state, and the rotation of the second body 120 relative to the first body 110 causes the first gear 132 to drive the second gear 134 engaged with the first gear 132 to rotate, thereby driving the gear 136 engaged with the second gear 134 to move linearly.

As the gear 136 moves, the second input module 116 is driven by the protrusion 136 a disposed in the track 116 a thereof to move upward to protrude from the housing 112 and be higher than the first input module 114 .

Similarly, after the second input module 116 changes its state relative to the housing 112, since the second input module 116 protrudes from the housing 112 and is higher than the first input module 114, an opening is formed between the second input module 116 and the housing 112, and the opening becomes the second air inlet 122' and the second air outlet 124' of the electronic device 100 to further enhance the heat dissipation effect of the electronic device 100.

As can be seen from FIG. 6 , in addition to the original first air inlet (not shown) and the first air outlet 110b’ of the electronic device 100’ as the main air inlet/outlet of the entire system, the second air inlet 122’ formed due to the height difference between the second input module 116’ and the housing 112 can serve as an auxiliary air inlet, and correspondingly, a second air outlet 124’ is provided on the side of the housing 112 adjacent to the second input module 116’ as an auxiliary air outlet, so that the electronic device 100’ in the open state has more than one heat dissipation path, which can effectively enhance the overall heat dissipation effect of the electronic device 100’.

In summary, in the electronic device of the present invention, the state of the second input module can be changed by opening the first host and the second host relatively, so that the user can identify the second input module more quickly and conveniently operate the second input module.

In addition, after the state of the second input module changes, the opening formed between the second input module and the housing can be used as an auxiliary air inlet/outlet, so that the electronic device has an additional heat dissipation path in addition to the main heat dissipation path, thereby effectively improving the overall heat dissipation effect of the electronic device.
