Embodiment

See also 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 B part of Fig. 3, and Fig. 5 is the synoptic 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 a main frame 30, a display screen 40, with a keyboard 50.Main frame 30 comprises a 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 a plurality of keycaps 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 the main frame 30, also can separate with main frame 30.

Keyboard 50 comprises a plurality of keycaps 51, a plurality of 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 a plurality of perforation 531.Keycap 51 lays respectively in the keycap hole 311 of casing 31, can form a gap S1 between keycap 51 and the keycap hole 311.Aforesaid keyboard 50 can be the various keyboards such as thin film type keyboard, mechanical keyboard or capacitance keyboard, because other thin section structures of keyboard 50 are not the emphasis of present embodiment, is therefore omitted.

Keycap 51 has a press surface 511, a plurality of side 512 and a supporting surface 513.Press surface 511 is positioned at outside the outside and keycap hole 311 of casing 31, and is available for users to press.Side 512 is adjoining around press surface 511, and extends to the inside of casing 31 in the outside of casing 31, that is keycap hole 311 can be run through and exceed in side 512.Supporting surface 513 is with respect to press surface 511, and adjoining in the side 512.Supporting surface 513 is positioned at the inside of casing 31, and is positioned at outside the 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 a plurality of the first air hole h1 and one second air hole h2.The first air hole h1 is arranged at that side 512, the second air hole h2 are arranged at supporting surface 513, the first air hole h1, the second air hole h2 and airflow space S2 is interconnected.Can be found out that by Fig. 4 and Fig. 6 the first air hole h1 is positioned at the outside in casing 31 and keycap hole 311, the second air hole h2 is positioned at the inside of casing 31.

See also Fig. 6, form a gas channel C1 between motherboard 32 and the 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), so that the heat of casing 31 inside is extracted out via gas channel C1.In present embodiment, the air of casing 31 outsides can enter casing 31 inside along an air flow path F1.For example, air can enter among the airflow space S2 via the first air hole h1.Afterwards, air via the second air hole h2 effluent stream space S 2 after, air can pass perforation and 531 enter gas channel C1.Via the first air hole h1 and the second air hole h2 on the main frame 30 of being distributed widely in of present embodiment, the air that can reduce casing 31 outsides enters the resistance of airflow space S2, to increase the radiating efficiency of main frame 30.

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

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

Please refer to Fig. 7 is the cross-sectional schematic of the second embodiment of notebook computer of the present invention.Be that 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, 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 outsides can enter keycap 51 via the first air hole h1a that is positioned at casing 31 outsides, and enter the inside of casing 31 via the first air hole h1a that is positioned at casing 31 inside, so keycap 51a can select not arrange the second air hole h2a.

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

Though the present invention discloses as above with various embodiment, however its only for example with reference to but not in order to limiting scope of the present invention, any those of ordinary skills, without departing from the spirit and scope of the present invention, when doing a little change and retouching.Therefore above-described embodiment is not to limit scope of the present invention, and protection scope of the present invention is as the criterion when looking appended the scope that claim defines.
