Embodiment
Fig. 2 is for being applied to the synoptic diagram of keyboard according to the height adjuster of the embodiment of the invention.Please refer to Fig. 2, the height adjuster 20 of present embodiment is used for keyboard 30, so the user can be according to the height and the angle of inclination thereof of required adjustment keyboard 30.In addition, keyboard 30 can be the employed keyboard of desktop PC, the employed keyboard of notebook computer or the employed keyboard of other electronic installations.This keyboard 30 comprises a plurality of button (not shown)s and a housing 300, and wherein these buttons are arranged in the housing 300, and the user can be by these button input data.In addition, housing 300 has opening 300a, and this opening 300a exposes part height adjuster 20.
Fig. 3 A is the exploded view according to the height adjuster of the embodiment of the invention, and Fig. 3 B is the constitutional diagram according to the height adjuster of the embodiment of the invention, and Fig. 3 C is first gear and the cylindrical stereographic map of Fig. 3 A.Please be simultaneously with reference to Fig. 3 A to Fig. 3 C, height adjuster 20 comprises fixture 232, right cylinder 234, first gear 236 and second gear 238.Wherein, fixture 232 is arranged on the housing 300 of keyboard 30, and fixture 232 has storage tank 232a and extend at least one interior support 232b of storage tank 232a so far.In the present embodiment, support 232b is hemispherical, yet support 232b also can be cylindric or other shapes.What in addition, present embodiment did not limit support 232b is provided with position and quantity.For example, the quantity of preferable support 232b is four, and support 232b is a copline with the bottom surface of housing 300 preferably.In the present embodiment, fixture 232 is one with housing 300, but fixture 232 and housing 300 also can be members independently.
In the present embodiment, the first fitting portion 234b is the cross protrusion, and second fitting portion, 23 6a are cross recess, yet in another embodiment, the first fitting portion 234b also can be altered to cross recess, and the second fitting portion 236a changes to the cross protrusion.Perhaps, the first fitting portion 234b also can be altered to a word protrusion, and the second fitting portion 236a is a word groove.In other words, the first fitting portion 234b and the second fitting portion 236a can be any two kinds can chimeric mutually structure, and when first gear 236 rotated, first gear 236 can drive right cylinder 234 and rotate.What deserves to be mentioned is that in the present embodiment, first gear 236 and right cylinder 234 are member independently, but first gear 236 and right cylinder 234 also can be one.
Fig. 4 is the another kind of right cylinder according to the embodiment of the invention.Please refer to Fig. 4 and Fig. 3 A, the right cylinder 334 of Fig. 4 is similar to the right cylinder 234 of Fig. 3 C, its difference is: the helical guideway 334a of right cylinder 334 has a plurality of positioning area 334b, and between each positioning area 334b and right cylinder 334 bottom surfaces at a distance of a preset distance.When support 232b when any positioning area 334b slides, the relative distance between right cylinder 334 bottom surfaces and the housing 300 is kept fixing.In other words, the different different angles of inclination of positioning area 334b representative that is to say that keyboard 30 can have the angle of inclination of multistage, so the user can select the angle of inclination of keyboard 30 according to demand own.
In sum, height adjuster of the present invention has following advantage at least:
One, by height adjuster of the present invention, the user can adjust the angle of inclination of keyboard according to the demand of itself.
Two, for notebook computer, because the angle of inclination of keyboard can adjust, so the space between keyboard bottom surface and the placed side also can strengthen, to improve the heat dissipation problem of notebook computer.
Though the present invention discloses as above with preferred embodiment; right its is not in order to limit the present invention; any person of ordinary skill in the field; without departing from the spirit and scope of the present invention; when can doing a little change and improvement, so protection scope of the present invention is as the criterion when looking the claim person of defining.
