Abstract
The utility model relates to a flexible keyboard, comprising a plastic circuit board 1. The utility model is characterized in that a plastic bursa body 2 with a cavity is positioned on the plastic circuit board 1, a lug boss 5 is positioned above a plurality of key-press breakover circuits on the plastic bursa body 2 that corresponds to the plastic circuit board 1, a convex key-press breakover trigger body 6 that is communicated with the plastic bursa body 2 is positioned on the lug boss 5, a feeding distance throat 3 of the plastic bursa body 2 is positioned on one side of the bursa body 2, a soft plug 4 is positioned at the tail end of the feeding distance throat 3. The plastic bursa body 2 can fill the plastic bursa body 2 through the feeding distance throat 3, and the four sides of the plastic bursa body 2 is fixedly connected with the plastic circuit board 1. The utility model is convenient to carry and easy to operate, has features of water resistance, dust resistance and exemption from cleaning, and is suitable for different types of IT products.
Description
One, technical field
The utility model belongs to the information products external equipment, particularly a kind of flexible keyboard.
Two, background technology
The profile of existing keyboard is fixed size.Most information product keyboard profile is solid-state, and volume is big, be not easy to carry, but meets people's button input habit, easy to operate; The portable information product adopts special-purpose miniature keyboard, can carry with portable information products, but its overall dimension is less, and button distributes and do not meet people's button input habit, operates very inconvenient; Have a spot of Foldable keyboard button to adopt the material of rubber one class, though collapsiblely reduce certain volume, the thickness after the two-fold is appointed the right 15mm of surpassing, and needs just can reduce thickness with the external force extruding.All these existing keyboards also have a common shortcoming, be exactly that each button contacts with circuit substrate by elastic material, the above gap of 3mm arranged, after use a period of time, can cause button and circuit substrate loose contact owing to the reason of dust, thus the input function of forfeiture button.
Three, summary of the invention
The purpose of this utility model is to provide a kind of and is easy to carry, easy to operate, the flexible keyboard of exempting to clean that is applicable to all types information products simultaneously again.
The purpose of this utility model is to adopt such technical scheme to realize, a kind of flexible keyboard, include plastic circuit board, be characterized on plastic circuit board, being provided with the plasticity utricule of a band cavity, top with respect to each button turning circuit in the plastic circuit board on the plasticity utricule is provided with boss, the below of boss is provided with the convex button conducting triggering body with plasticity utricule inwall communications and liaison, one side of plasticity utricule is provided with the packing material charging aperture, the charging aperture tail end has cork, but the plasticity utricule is from charging aperture filling packing material, and four limits of plasticity utricule and plastic circuit board connect firmly and be integral.
When using the utility model, insert packing material from the packing material charging aperture, the jam-pack cork, when just being in key-press status, keyboard appearance profile volume is bigger, is similar to common keyboard, meets people's button custom, and is easy to operate, comfortable; Back out cork, discharge the packing material in the plasticity utricule, the soft contraction state that is in of utricule, the keyboard overall volume is less, the outline body after it shrinks during only less than key-press status keyboard appearance profile volume 1/5th.
Owing to adopted above technical scheme, made the keyboard profile to change as required.During user's operation keyboard, flexible keyboard just becomes the keyboard that meets people's button custom, and operation as snug as a bug in a rug, conveniently.When the operator does not use information products and during the shut-down operation keyboard, flexible keyboard through shrink, volume after folding is very little, can be less than keyboard of notebook computer.Because plasticity utricule and plastic circuit board are fixedly connected, so waterproof, anti-gray is exempted from cleaning, are easy to carry, easy to operately are applicable to various types of information products.
Four, description of drawings
The utlity model has following accompanying drawing:
Structural representation when Fig. 1 finalizes the design state for the utility model;
The schematic diagram of button when Fig. 2 finalizes the design state for the utility model;
The schematic diagram of button when Fig. 3 is the utility model contraction state;
Fig. 4 is the utility model shrinks after folding schematic diagram.
Among the figure: the conducting of 1-plastic circuit board 2-plasticity utricule 3-charging aperture 4-cork 5-boss 6-button triggers body
Five, embodiment
Below in conjunction with accompanying drawing the utility model is further described.As shown in Figure 1 and Figure 2, a kind of flexible keyboard, include plastic circuit board 1, be characterized on plastic circuit board 1, being provided with the plasticity utricule 2 of a band cavity, top with respect to each button turning circuit in the plastic circuit board 1 on the plasticity utricule 2 is provided with boss 5, the below of boss 5 is provided with the convex button conducting triggering body 6 with plasticity utricule 2 inwall communications and liaison, one side of plasticity utricule 2 is provided with packing material charging aperture 3, charging aperture 3 tail ends have cork 4, but plasticity utricule 2 is from charging aperture 3 filling packing materials, and four limits of plasticity utricule 2 and plastic circuit board 1 connect firmly and be integral.On the end face of button conducting triggering body 6 conductive rubber is arranged.The air of packing material in the plasticity utricule 2 for being blown into from charging aperture 3.Among another embodiment, the packing material in the plasticity utricule 2 is the water that sucks from charging aperture 3.Plastic circuit board 1 adopts paster welding or flexible printed circuit board.When needing typing, open cork, inject packing material to the distortion shell inner cavity, the plasticity utricule is fully expanded, after covering cork, soft shell keeps profile, as shown in Figure 1 and Figure 2.After opening cork, light compactibility utricule is discharged the packing material in the inner chamber, and soft shell fully shrinks, and becomes the shape that is similar to a piece of cloth, at this moment can fold, curl, as shown in Figure 3, Figure 4.Because the flexible keyboard shell is disposal molding, airtight fully, therefore do not advance dust, can put into the water clean surface, can be under multiple adverse circumstances operate as normal.
