Embodiment

Refer to Fig. 3 to Fig. 6, Fig. 3 is the stereographic map of the first embodiment of notebook computer 2 of the present invention, Fig. 4 is the enlarged drawing of the part B of Fig. 3, and Fig. 5 is the schematic diagram of the first embodiment of keycap 51 of the present invention, and Fig. 6 is the cross-sectional schematic of the first embodiment of notebook computer 2 of the present invention.

Notebook computer 2 comprise main frame 30, display screen 40, with a keyboard 50.Main frame 30 comprises casing 31 and a motherboard 32.Casing 31 can be a hollow structure, and casing 31 is provided with a keyboard area Z1, is provided with multiple keycap hole 311 in keyboard area Z1.Motherboard 32 is arranged at the inside of casing 31, and motherboard 32 can comprise the elements such as central processing unit (not shown).Display screen 40 can be coupled on main frame 30, also can be separated with main frame 30.

Keyboard 50 comprises multiple keycap 51, multiple support unit 52 and a button substrate 53.Keycap 51 is arranged at button substrate 53 via support unit 52, and button substrate 53 is arranged at the inside of casing 31, and is provided with multiple perforation 531.Keycap 51 lays respectively in the keycap hole 311 of casing 31, can form a gap S1 between keycap 51 and keycap hole 311.Aforesaid keyboard 50 can be the various keyboards such as thin film type keyboard, mechanical keyboard or capacitance keyboard, and other the thin portion structures due to keyboard 50 are not the emphasis of the present embodiment, are therefore omitted.

Keycap 51 has a press surface 511, multiple side 512 and a supporting surface 513.Outside the outside that press surface 511 is positioned at casing 31 and keycap hole 311, and be available for users to pressing.Side 512 is adjoining in the surrounding of press surface 511, and extends to the inside of casing 31 in the outside of casing 31, that is side 512 can be run through and exceed keycap hole 311.Supporting surface 513 is relative to press surface 511, and adjoining in side 512.Supporting surface 513 is positioned at the inside of casing 31, and is positioned at outside keycap hole 311.

Keycap 51 can be the shell structure of a hollow, and forms an airflow space S2 in the inside of keycap 51, and keycap 51 has multiple first air hole h1 and one second air hole h2.First air hole h1 is arranged at side 512, second air hole h2 and is arranged at supporting surface 513, and the first air hole h1, the second air hole h2 and airflow space S2 are interconnected.Can be found out by Fig. 4 and Fig. 6, the first air hole h1 is positioned at the outside in casing 31 and keycap hole 311, and the second air hole h2 is positioned at the inside of casing 31.

Refer to Fig. 6, form a gas channel C1 between motherboard 32 and button substrate 53, the first air hole h1, the second air hole h2, perforation 531 and gas channel C1 are interconnected.Generally speaking, the inside of notebook computer 2 can be provided with a fan (not shown), the heat of casing 31 inside to be extracted out via gas channel C1.In the present embodiment, the air of casing 31 outside can enter casing 31 inside along an air flow path F1.For example, air can enter in airflow space S2 via the first air hole h1.Afterwards, air is via after the second air hole h2 effluent stream space S 2, and air can enter gas channel C1 through perforation 531.Be distributed widely in the first air hole h1 on main frame 30 and the second air hole h2 via the present embodiment, the air that can reduce casing 31 outside enters the resistance of airflow space S2, to increase the radiating efficiency of main frame 30.

Another in the present embodiment, air directly can flow directly into the inside of casing 31 via gap S1.When aforesaid fan shuts down, air also can be flow to the outside of casing 31 by gas channel C1 according to the reverse direction of air flow path F1.In addition, in order to air can be reduced further through the resistance of perforation 531, the button substrate 53 between two adjacent keycaps 51 can arrange perforation 532.

In sum, in the present embodiment, the gap S1 in keycap 51 and keycap hole 311, can reduce as much as possible in not hindering keycap 51 to press when, the air of casing 31 outside can enter the inside of casing 31 via the first air hole h1 and the second air hole h2, can't hinder the heat radiation of notebook computer 2.

Please refer to the cross-sectional schematic that Fig. 7 is the second embodiment of notebook computer of the present invention.Be with the first embodiment main difference part, the length of the first air hole h1a of keycap 51a is longer, that is the length of the first air hole h1a is greater than the length in keycap hole 311, and the first air hole h1a is exposed to inside and the outside of casing 31.Support unit 52a arranges the middle body of supporting surface 513a, and the second air hole h2a can be arranged at the edge of supporting surface 513a.In another embodiment, because the air of casing 31 outside can enter keycap 51 via the first air hole h1a being positioned at casing 31 outside, and the inside of casing 31 is entered via the first air hole h1a being positioned at casing 31 inside, therefore keycap 51a can select not arrange the second air hole h2a.

As shown in Figure 7, air can via an air flow path F2 from gas channel C1, perforation 531,532 to the first air hole h1a and the second air hole h2a.Finally, air flow to the outside of casing 31 via the first air hole h1a.Air also can flow in gas channel C1 according to the reverse direction of air flow path F2.

Though the present invention discloses as above with various embodiment, but it is only exemplary reference and is not used to limit scope of the present invention, any those of ordinary skill in the art, without departing from the spirit and scope of the present invention, when doing a little change and retouching.Therefore above-described embodiment be not used to limit scope of the present invention, protection scope of the present invention is as the criterion when the scope that define depending on appended claim.
