Embodiment
By reference to the accompanying drawings the present invention is described in further detail below by embodiment.
In the embodiment of the present application, press-key structure comprises key body, first circuit board (PCB) and the second circuit board (FPC) of light-permeable.The parts of this key body (or being called the key shell) for finally directly being operated by the user, it can adopt light-transmitting materials to make, and has good light transmission, materials such as zircon, crystal, toughened glass, transparent plastic.Be provided with on-off switch in the position of corresponding keys body on the first circuit board, this on-off switch is a kind of triggering switch between key body and first circuit board, Main Function is resilience and energising, and on-off switch can adopt key spring plate structure (being commonly called as again the young sheet of pot, metal dome or snap dome).Second circuit board is arranged on the on-off switch, and it is electrically connected with first circuit board.Second circuit board is provided with illuminating part, and this illuminating part is directly powered by second circuit board, thus so that illuminating part is located immediately at the below of key body, the light that illuminating part produces all or major part directly appear from the key body, improve the light transmission of button.Because on-off switch and illuminating part are the levels designs, and the position of illuminating part arranges the position that does not affect on-off switch and arranges, therefore the relative position of on-off switch and key body can be set arbitrarily as required simultaneously, guarantee handfeel of keys.
Utilize specific embodiment to further specify below in conjunction with accompanying drawing:
Embodiment one:
Please refer to Figure 4 and 5, press-key structure specifically comprises key body 21, first circuit board 22, key spring plate 23, second circuit board 25, stainless steel sheet material 26 and button silica gel 28 in the present embodiment one.
Key body 21 is the zircon assembly, and zircon color and luster gorgeous and transparent flawless and refractive index and dispersion values height can produce gorgeous color under the irradiation of illuminating part.Key body 21 can cut into various shapes, and is square, square etc. such as annular, circle, egg type, triangle, pyriform, horse-eye shape, rectangle, heart, five-pointed star shape, quincunx, axe-shape, sphere, ladder.Simultaneously, also can set up other ornament materials at zircon, such as crystal etc., to enhance each other's beauty with zircon, improve key body 21 aesthetic properties.Please refer to Fig. 6, in the present embodiment one, zircon assembly 21 comprises zircon and decoration 28, and this zircon circularizes shape, and the bottom arranges a circle fin, is used for covering the illuminating part on the first circuit board 22.Boudle part 28 in the central slot of annular shape zircon, this decoration 28 can be quartzy decoration, so that the light that illuminating part produces back and forth refraction between zircon and decoration 28 produces the effect that enhances each other's beauty.
First circuit board 22 is printed circuit board (PCB) (PCB), which is provided with the key spring plate 23 corresponding with key body 21 positions as on-off switch, key spring plate 23 is positioned at the conducting position (major part is positioned at the golden finger top on the wiring board) on the pcb board, when being subject to pressing, the central point of shell fragment is recessed, touch the circuit on the PCB, thereby form the loop, electric current passes through.Key spring plate 23 can adopt for example circular metal shell fragment, cross metal clips, triangle metal shell fragment, oval metal clips.
Second circuit board 25 is flexible PCB, because flexible PCB itself has bent characteristic, therefore only occupies less space, is conducive to cramped construction.Flexible PCB is arranged on the top of key spring plate 23, and it is electrically connected with printed circuit board (PCB), and electric connection mode can adopt scolding tin connection, plate that plate is connected or zero resistance socket (Zero Insertion Force, ZIF) connector connects.Flexible PCB is provided with illuminating part 24 in the present embodiment, illuminating part 24 is located immediately at the below of key body 21, for example can be close to key body 21 bottoms and arrange or only stay narrow and small slit, thereby appear raising key body 21 light transmittances from key body 21 so that the luminous energy that illuminating part 24 sends is whole or most of.Further, key body 21 is located on the flexible PCB, and covers illuminating part 24, so that the light that illuminating part 24 sends is closed in the key body 21, can avoid further light leak.This illuminating part 24 can adopt the LED lamp, and it is directly powered to illuminating part 24 by flexible PCB, when key spring plate 23 is pressed down connection, and illuminating part 24 work; When key spring plate 23 resiliences, circuit disconnects, and illuminating part 24 stops luminous.
Stainless steel sheet material 26 and button silica gel 28 are arranged between flexible PCB and the key spring plate 23 from top to bottom in turn, its effect is when user's pressing keys, in order to transmit and diffusion pressure, can improve the even feel of button, the comfortableness when improving user's use.Stainless steel sheet material 26 shapes and key body 21 shapes are suitable, and for example key body 21 is circular in the present embodiment, 26 one-tenth semicircle settings of stainless steel sheet material.
During concrete operations, key body 21 under the operator presses, so that key body 21, flexible PCB, stainless steel sheet material 26 and button silica gel 28 press down together, so that key spring plate 23 distortion, the central point of shell fragment is recessed, touches the circuit on the printed circuit board (PCB), so that circuit communication, thereby the LED lamp is bright, and light is whole or most of to appear from key body 21, and the button brightness effect is obvious; Operator's reverse keys body 21 subsequently, key spring plate 23 be because self spring return, causes key body 21, flexible PCB, stainless steel sheet material 26 and button silica gel 28 to move on together, and last loop disconnects, and the LED lamp goes out.
In the present embodiment, press-key structure not only can improve light transmittance, reduce light leak, and the brightness of button printing nonopaque is by circuit and voltage adjustment, and light guiding film and black gum are set between prior art illuminating part 24 and the key body, utilize the light guiding film brightness adjusting to compare, circuit and voltage are adjusted convenient and accurate.Adopt this press-key structure because flexible PCB directly is electrically connected with printed circuit board (PCB), can save the ESD(conducting foam), save manufacturing cost.Flexible PCB itself has frivolous, bent characteristic, therefore can be adapted in the compacter space, so that this press-key structure is smaller and more exquisite, only occupies less space.
Embodiment two:
Please refer to Fig. 4 and 6, present embodiment two discloses a kind of electronic equipment, this electronic equipment comprises housing 27 and embodiment one press-key structure of describing, wherein key body 21 is fixedly mounted on the housing 27, its part exposes to outside the housing 27, and printed circuit board (PCB), flexible PCB and other parts all are installed in the housing 27.Housing 27 is provided with corresponding through hole, and the zircon assembly passes from through hole, and its bottom arranges block, blocks the location with housing 27 through hole hole walls.
This electronic equipment can be that mobile phone, base, display, remote controller and other have the electronic equipment of physical button.Ok key or acknowledgement key that this press-key structure can be used as electronic equipment use, and also can be used as digital keys, Menu key or other buttons and use.
Further, press-key structure on this electronic equipment can comprise at least two key bodies 21, these at least two key bodies 21 are along row, column or irregular arranging, these a plurality of key bodies 21 can all share second circuit board 25, also can second circuit board 25 of partial common, can also distinguish separately second circuit board 25 corresponding to configuration.
Above content is the further description of the present invention being done in conjunction with concrete execution mode, can not assert that implementation of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace.
