Abstract
The utility model provides a water-proof keyboard structure, which comprises a base plate, keycaps arranged above the base plate, an elastic body arranged between the keycaps and the base plate, an X-structure scissor mounted between the keycaps and the base plate and a thin film circuit board arranged below the base plate, wherein a through hole is formed in the base plate and corresponds to the elastic body, and when pressed by the keycaps, the elastic body penetrates through the through hole and is pressed against the thin film circuit board. By the water-proof keyboard structure, the thin film circuit board is arranged below the base plate, so that a hole corresponding to the X-structure scissor is not required to be formed in the thin film circuit board, water flowing through the thin film circuit board cannot enter the keyboard, and a good water-proof effect is achieved.
Description
Technical field
The utility model relates to a kind of keyboard, particularly a kind of Water-preventing keyboard structure.
Background technology
Keyboard is widely used in the input of computer and various electronic product equipment as a kind of common input unit.Along with being widely used of electronic product, keyboard occupies very consequence as man-machine communication's means in whole system.As shown in Figure 1, the structure of the existing keyboard that uses generally is comprised of keycap 100, scissor 200, rubber elastomer 300, film circuit board 400 and substrate 500 etc., keycap 100 is installed on the substrate 500 by scissor 200, and film circuit board 400 places between substrate 500 and the scissor 200.The keyboard of existing this kind structure, film circuit board 400 is positioned at substrate 500 tops, hole 410 need to be set so that the installation of scissor 200 on substrate 500, and when the situation of water inlet occurs in keyboard, the water capacity easily flows on the film circuit board 400, and flow in the keyboard by the hole 410 on the film circuit board 400, affect keyboard and normally use.
The utility model content
The purpose of this utility model is to provide a kind of Water-preventing keyboard structure, and it is arranged on the substrate below with film circuit board, and film circuit board need not established the hole, avoids water to flow in the keyboard, has waterproof action.
For achieving the above object, the utility model provides a kind of Water-preventing keyboard structure, it comprises: substrate, be located at substrate top keycap, be located at elastomer between keycap and the substrate, be installed in the scissor between keycap and the substrate and be located at the film circuit board of substrate below, corresponding elastomer is provided with through hole on the substrate, passes through hole after elastomer is pressed by keycap and presses film circuit board.
Described keycap can move up and down by scissor and be supported in the substrate top, is formed with hollow-out parts in the middle of the scissor, and elastomer is arranged in this hollow-out parts.
Described substrate is aluminium sheet.
The beneficial effects of the utility model: the utility model is by being arranged on film circuit board substrate below, thereby do not need corresponding scissor to establish the hole on the film circuit board, avoided water to flow in the keyboard through film circuit board, has good waterproof action.
In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet accompanying drawing only provide with reference to and the explanation usefulness, the utility model is limited.
Description of drawings
Below in conjunction with accompanying drawing, by embodiment of the present utility model is described in detail, will make the technical solution of the utility model and other beneficial effect apparent.
In the accompanying drawing,
Fig. 1 is the decomposing schematic representation of existing keyboard structure;
Fig. 2 is the decomposing schematic representation of Water-preventing keyboard structure of the present utility model.
Fig. 3 is the combination schematic diagram of Fig. 2.
Embodiment
Technological means and the effect thereof taked for further setting forth the utility model are described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
Shown in Fig. 2-3, Water-preventing keyboard structure of the present utility model comprises: substrate 2, be located at substrate 2 tops several keycaps 4, be located at elastomer 3 between keycap 4 and the substrate 2, be installed in the scissor 6 between keycap 4 and the substrate 2 and be located at the film circuit board 8 of substrate 2 belows.
Described keycap 4 can move up and down by scissor 6 and be installed on substrate 2 tops, is formed with hollow-out parts 60 in the middle of the scissor 6, and elastomer 3 is arranged in this hollow-out parts 60.Corresponding elastomer also is provided with through hole 22 on the described substrate 2, passes through hole 22 after elastomer is pressed by keycap 4 and presses film circuit board 8, so that the circuit contact on the film circuit board 8 (not shown) is realized circuit turn-on, thereby realizes the input of keyboard.Elastomer 3 can be arranged on the film circuit board 8 with bonding mode by its bottom edge.
Described substrate 2 is aluminium sheet, can carry out as required the thinning setting.Described film circuit board 8 is arranged on substrate 2 belows, so does not need corresponding scissor 6 to establish the hole on it, so that this film circuit board 8 is the whole piece structure, has waterproof action.When keyboard generation flooded condition, water can not enter in the keyboard by film circuit board 8, guarantees the normal use of keyboard.
In sum, the utility model is by being arranged on film circuit board substrate below, thereby do not need corresponding scissor to establish the hole on the film circuit board, avoided water to flow in the keyboard through film circuit board, has good waterproof action.
The above; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to the technical solution of the utility model and technical conceive, and all these changes and distortion all should belong to the protection range of the utility model claim.
