Description

A kind of ultrathin button keycap

Technical field

The utility model relates to the button keycap on a kind of computer keyboard, relates in particular to a kind of ultrathin button keycap.

Background technology

Existing various keyboard is mostly by keycap, the keycap guide groove, the key panel, caoutchouc elasticity touches body and the contact wiring board is formed, the rectangle inserting column that keycap extends by its below is installed in the rectangle keycap guide groove, down on time, the convex shake-up body that caoutchouc elasticity touches body contacts soft silver point circuit board, upper contact passes thermal insulation board circular hole contact contact turning circuit down, these keyboards all have general defective, that be exactly in use keycap very easily rock, the frictional force that keycap is subjected in the process of moving up and down is bigger, make knock smooth and easy inadequately comfortable, be easy to generate noise and card key phenomenon, and keycap is higher, and the keyboard overall weight is big, and is slim and graceful inadequately, it is very poor to beat feel, and long-time use makes the people feel fatigue easily.

The utility model content

At the deficiencies in the prior art, the purpose of this utility model is to provide that a kind of profile smoothness is frivolous, comfortable feel is smooth and easy, wave the little ultrathin button keycap of amplitude.

For achieving the above object, the ultrathin button keycap of the utility model comprises lid and is positioned at the rectangle inserting column of lid below, lid is flat, the both sides at four jiaos of places of inserting column are provided with the elongated sliver of longitudinal extension, be provided with elastic fastening hook to the inserting column bilateral symmetry, the grab both sides are provided with the space.

Further, the height of described lid is 3～5mm, and the height of described inserting column is 6～9mm.

Further, described lid is towards 54 °～58 ° of user's one side direction outer inclines, outward-dipping 36 °～44 ° of both sides, outward-dipping 4 °～6 ° of dorsal part.

Further, the cheicers place of described grab is provided with the noise reduction inclined-plane, and the grab inboard is provided with floor.

Further, described grab is outward-dipping, and the angle of itself and inserting column axis is 0 °～20 °.

Further, the cross section of described sliver is the semi-circular projection shape.

Further, be provided with the right-angled intersection post in the cavity of described inserting column, the height of this right-angled intersection post is lower than the height of inserting column.

Further, described card structure top is lower than the end face of inserting column, forms gap in the inserting column both sides.

Further, the knocking of described lid towards interior recessed, each crest line place on surface all leads fillet.

Further, be provided with card structure and the guide cylinder that is used for clamping button balancing pole below the described lid.

Keycap of the present utility model is designed to the flat of ultra-thin shape, shortened the thickness that knocks key journey and keyboard greatly, be equipped with high-quality high resiliency silica gel shake-up body and can effectively promote time power sense and the elasticity that keyboard knocks, beat more comfortable lighter, be rich in the rhythm and elasticity, the therefore long-time finger that uses can be too not tired yet, and surperficial equilibrium treatment, camber line slightly in the Founder, it is mellow and full comfortable to stroke up feel.The keycap design of matrix allows the user paste thereon with the most natural posture, makes each button knock lighter nature, has improved input efficiency.

Inserting column of the present utility model four Jiao Chu both sides are provided with the elongated sliver of longitudinal extension, can be slidingly matched with the smooth inner wall of guide groove, owing to be line face contact movement, therefore contact-making surface is few, reduced the mobile frictional force of guiding up and down, prolonged the useful life of keyboard, and keyboard beats also send clear and melodious sound unlike common keyboard, fixedly silica gel structure firmly is difficult for off normal, make that to knock more smooth and easy shaking amplitude little, which part of user's contact-key face no matter, stressed all very even, can enjoy smooth and easy and consistent feel, the power that hooks together of grab and keycap guide groove can be effectively controlled in the space of grab both sides, keycap can or not knocked energetically because of vibrations to come off, during the keycap bounce-back, the inclined-plane at card structure cheicers place is done oblique point with the bending inwall of keycap guide groove and is contacted, and is difficult for rocking and producing noise, and below long lid, balancing pole card structure is set, then guarantee to knock any place of key cap surface and card key phenomenon all can not occur interfering.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Extremely shown in Figure 6 as Fig. 1, lid 1 roughly is flat square cap-like structure, and it is slightly inwardly recessed that it knocks face, and each crest line place, surface all leads fillet, the smooth smoothness of lines, and have certain gradient, meet ergonomics, the lid height is 3mm, the inserting column height is 8.2mm, lid is towards 56 ° of user's one side direction outer inclines, outward-dipping 44 ° of both sides, outward-dipping 5 ° of dorsal part.The inserting column 2 that extend lid 1 below is rectangle, be hollow-core construction, inside is provided with right-angled intersection post 3, the height of right-angled intersection post 3 is lower than the height of inserting column 2, the both sides at four jiaos of places of inserting column 2 are provided with the elongated sliver 4 of longitudinal extension, the cross section of sliver 4 is semicircle shape, inserting column 2 both sides also are provided with elastic fastening hook 5 symmetrically, and grab 5 both sides are provided with space 6, and the cheicers place of grab 5 is provided with noise reduction inclined-plane 7, the grab inboard is provided with floor 8, grab 5 outward-dipping 20 ° of angles, the top of card structure 5 is lower than the end face of inserting column 2, forms gap in the both sides of inserting column 2, knocking towards interior recessed of lid 1, each crest line place on surface all leads fillet.
