Abstract
The present invention relates to a low noise keyboard and a notebook computer having the keyboard, wherein the notebook computer comprises a shell, a fan and a keyboard, wherein the keyboard comprises a base board, a plurality of elevating components, a plurality of key caps and a plurality of through holes. The fan is arranged in the shell and is used for generating circular air flow in the shell. The base board is also arranged in the shell, and the elevating components are respectively arranged on the base board. The key caps are arranged on the elevating components, and the through holes are respectively formed on the base board and are not overlapped with projection parts of the elevating components on the base board. When the elevating components are elevated, the air flow generated by the fan is easy to pass through the through holes, and thus, the generation of noise can be reduced.
Description
(1) technical field
The relevant a kind of notebook of the present invention, particularly relevant a kind of notebook with low noise keyboard.
(2) background technology
In recent years, it is very universal to use a computer, and the relative adaptation ease of use notebook so develop successively, yet because the speed of the central processing unit (CPU) in the present notebook is more and more faster, the heat release that it produced also relatively improves; In order to solve the heat dissipation problem of central processing unit, the deviser have to strengthen fan dimension (size), to improve usefulness (performance), though can solve heat dissipation problem a little, noise is increased.
With reference to figure 1b and Fig. 1 c, Fig. 1 b is a three-dimensional exploded view of commonly using the keypad portion 3 of notebook 100, and Fig. 1 c is a diagrammatic cross-section of commonly using the one key in the keypad portion 3.The keypad portion 3 of commonly using notebook 100 includes a plurality of keycaps (only showing among Fig. 1 b that a keycap is as representative) 11, a plurality of lift component (only showing among the figure that a lift component is as representative) 12, one elastic thin layer 13, a circuit film 14 and a substrate 15, it should be noted that Fig. 1 b is a synoptic diagram, wherein in order to allow the people more know the structure of keycap 11, lift component 12, and this two assembly is slightly amplified, so the size between each assembly and incorrect.Each part division of keypad portion 3 is as follows:
Elastic thin layer 13 also is arranged in the computer body 1, the rubber that it is formed in one, and have a sheet body 130, a plurality of elastic body 131, connecting portion 133 and through hole 132, wherein be connected by connecting portion 133 between elastic body 131 and the sheet noumenon 130.
In addition, with reference to figure 1b, during assemblying keyboard, circuit film 14 and elastic thin layer 13 overlay on the substrate 15, make the bearing 151 of substrate 15 and grab 152 pass through hole 141 on the circuit film 14 and the through hole 132 on the elastic thin layer 13 in regular turn.Lift component 12 is arranged between substrate 15 and the keycap 11 in the mode that allows keycap 11 to move up and down, and wherein first end the 1211, the 1221st of bracing frame 12 is connected in the bearing 151 and crotch 152 of substrate 15.And second end the 1212, the 1222nd of bracing frame 12 is connected in the pothook and the clamping part (not shown) of keycap 11.
During operation keyboard, the user pushes keycap 11, and keycap 11 sinks and is urged to elastic body 131, makes elastic body 131 distortion, and can be urged to the corresponding point of circuit film 14 once prominent point in the elastic body 131, make circuit film 14 send corresponding signal in this conducting.
The above is structure and a principle of operation of commonly using the keyboard of notebook, in described explanation and relevant known techniques, can find known when making the keyboard of notebook, all do not reduce noise at keypad portion for notebook integral body especially, especially propose improvement at user's its relative influence when beaing keyboard for fan noise.
The present inventor is promptly at described problem further investigation, find known when making the substrate 15 of keypad portion 3, can be at bearing 151 and the crotch 152 other through holes 153 that produce, the circulating current that produces with the fan 16 of convenient position below substrate 15 flow to the external world by substrate 15, shown in Fig. 1 b; In addition, if the view field of lift component 12 on substrate 15 represented with symbol P, can find that the view field of lift component 12 on substrate 15 will be overlapping with through hole 153, shown in Fig. 1 d; It should be noted in Fig. 1 d, only show the smooth projected area on substrate 15 time of lift component 12, do not demonstrate lift component 12 with respect to the projected area of substrate 15 when tilting, but difference between the two can't influence the following description.
Based on known design, because through hole 153 is to be arranged in the view field P of lift component 12 on substrate 15, therefore when the user pushes the keycap 11 of keypad portion 3, first bracing frame 121 of lift component 12 and the lifting action of second bracing frame 122, can hinder the through hole 153 of the circulating current of fan 16 generations of position below substrate 15 by substrate 15, though known through hole 153 can reach enough inlet air effects, too much because of through hole 153 numbers, and can cause meaningless noise.
(3) summary of the invention
In view of this, the object of the present invention is to provide a kind of keyboard of low noise and have the notebook of this keyboard, it can effectively reduce number of through-holes under the function of keeping the inlet air abundance, with effective reduction noise, and when the user pushes or does not press keyboard, equal circulating currents that can not hinder or disturb fan inside to produce.
For achieving the above object, a kind of low noise keyboard is provided according to an aspect of the present invention, be used for a notebook, wherein notebook has a housing and a fan, and described low noise keyboard comprises a substrate, a plurality of lift component, a plurality of keycap and a plurality of through hole; Substrate is arranged in the housing, and lift component is arranged at respectively on the substrate, and keycap is arranged on the lift component respectively; Through hole be respectively formed on the substrate and not with the overlapping part of the projection section of lift component on substrate, by this when the lift component lifting, allow air-flow that fan produces easily by through hole, produce and reduce noise.
A kind of notebook is provided according to a further aspect of the invention, comprises a housing, a fan, a substrate, a plurality of lift component, a plurality of keycap and a plurality of through hole; Fan is arranged in the housing, in order to produce a circulating current in housing; Substrate is arranged in the housing, and lift component is arranged at respectively on the substrate, and keycap is arranged on the lift component respectively; Through hole be respectively formed on the substrate and not with the overlapping part of the projection section of lift component on substrate, by this when the lift component lifting or when motionless, allow air-flow that fan produces easily by through hole, produce thereby reduce noise.
In another preferred embodiment, through hole is respectively formed on the substrate, not with the overlapping part of the projection section of keycap on substrate, when keycap moved, its air communication that can not stop that fan produces was crossed through hole by this, and the circulating current that disturbs fan to produce.
For further specifying purpose of the present invention, design feature and effect, the present invention is described in detail below with reference to accompanying drawing.
