Embodiment
As shown in Figure 1, the utility model preferred embodiment has the press-key structure 9 of key panel, can be applicable to various engineering electronic equipments, comprises key panel 1, a plurality of button indicator light group and circuit board 3.Wherein, key panel 1 is covered on circuit board 3; A plurality of button indicator light groups are arranged on circuit board 3, by the circuit supply on circuit board 3 and control, are used to indicate the operating state of button, and the light that each indicator light 21 in a plurality of button indicator light group sends can pass through key panel 1.
See also Fig. 2-4, key panel 1 of the present utility model is provided with a plurality of buttons 11 and a plurality of light shielding block 12.
The first surface 111 of each button 11 protrudes from the outer surface 13 of key panel 1, for user, presses, and its second 112 items relative with first surface 111 are provided with conductive base 113, with corresponding with set conducting strip (not shown) on circuit board 3.Each button 11 1 sides can correspondence arrange a button indicator light group, and included indicator light 21 quantity of each button indicator light group can be identical or different; Certainly, can in part button 11 1 sides, indicator light 21 be set as required, 11 of part buttons do not arrange yet.In another preferred embodiment, press-key structure of the present utility model also can only comprise a button indicator light group.When press-key structure is only provided with one group of button indicator light group, this button indicator light group comprises a plurality of indicator lights 21; And when press-key structure is provided with many group button indicator light groups, each button indicator light group can comprise one or more indicator lights 21.In the present embodiment, as shown in the figure, each button 11 1 side correspondences are provided with a button indicator light group, and each button indicator light group comprises 3 indicator lights 21, can send ruddiness, gold-tinted, green glow respectively.But the quantity of the corresponding indicator light 21 of each button 11 and the color presenting thereof, be not limited to this, it can be set according to demands such as actual function or outward appearances.
A plurality of light shielding block 12 are embedded in key panel 1, corresponding one by one with a plurality of button indicator light groups respectively, are positioned at a side of respective keys 11.In another preferred embodiment, when the utility model press-key structure only comprises a button indicator light group, on key panel 1, also correspondence only arranges a light shielding block, and the two is positioned at a side of a respective keys.This light shielding block 12 is to be made by light-proof material, can adopt with key panel 1 post-forming process and form, and also can directly be assemblied in key panel 1.In the present embodiment, key panel 1 comprises button 11 employing transparent silica gel materials, and light shielding block 12 adopts black silicon glue material, and the two through post-forming process together.Each indicator light 21 in each light shielding block 12 in corresponding respective keys indicator light group (being in the present embodiment 3) is provided with respective through hole 121 (being in the present embodiment 3), isolated by the light-proof material of light shielding block 12 between adjacent through-holes 121, therefore light cannot pass through, and reaches the effect of light isolation.Therefore, when each indicator light 21 is arranged in respective through hole 121, the light that each indicator light 21 sends can only be propagated up and down, and the light that can not send with adjacent indicator light 21 forms printing opacity interference.
The concrete mode being embedded in key panel 1 for light shielding block 12 at this describes.In the present embodiment, key panel 1 in the inner surface 14 is provided with a plurality of grooves 16, corresponding one by one with a plurality of light shielding block 12.Set each through hole 121 of the corresponding corresponding light shielding block 12 in bottom of each groove 16, is provided with transmittance section 17 (being in the present embodiment 3), and this transmittance section 17 can be essence hole, and for example loophole, can adopt radium technology for fast carving on to form; Also can be non-essence hole, for example, by light transmissive material, make in other words and formed by translucent element.A plurality of light shielding block 12 are embedded at respectively in corresponding recesses 16, and on it, set through hole 121 is corresponding one by one with the transmittance section 17 of groove 16 bottoms, make to be arranged in the light that the indicator light 21 of through hole 121 sends and can pass this key panel 1 via this transmittance section 17.
In another embodiment, key panel 1 in the inner surface 14 is provided with a plurality of perforation that run through key panel 1, corresponding one by one with a plurality of light shielding block 12.The plurality of light shielding block 12 is embedded at respectively in respective perforations, is located at the light that the indicator light 21 in light shielding block 12 through holes 121 sends and can directly by through hole 121, passes this key panel 1.
In addition, the part in a plurality of light shielding block of the present utility model can be connected with whole light shielding block, so that machine-shaping.For example, in the present embodiment, as shown in Figure 3, a plurality of light shielding block of the button homonymy being in line connect successively, become one, and correspondingly, the groove of its place key panel 1 or perforation are also connected, and become one, so that machine-shaping.This mode being connected is not limited to this, and can adjust accordingly according to the actual key situation of arranging, and for the purpose of easy to process, even whole light shielding block can be connected, and becomes one.That is to say, light shielding block and button indicator light group corresponded manner quantitatively, also can now to the dividing mode of light shielding block is different, change to some extent because of it, as long as guarantee that a plurality of indicator lights that need carry out light isolation lay respectively in a plurality of through holes of light shielding block, make to carry out light isolation by light shielding block between adjacent indicator light.
Key panel 1 of the present utility model and press-key structure 9 are when application, and key panel 1 is covered on circuit board 3, and the indicator light 21 of being located at the many groups button indicator light group on circuit board 3 stretches in the through hole 121 of corresponding light shielding block 12.When indicator light 21 is worked under the control of circuit board 3, its light sending can only be propagated up and down along through hole 121 in through hole 121, upwards pass through hole 121 (key panel 1 in the inner surface 14 is provided with in the situation of perforation), or through hole 121 and transmittance section 17, to next, by circuit board 3, blocked, between adjacent indicator light 21, by light shielding block 12, carry out light isolation.Thus, in the time of can avoiding work, between a plurality of indicator lights 21 of same button 11 correspondences and/or between the indicator light 21 of adjacent two button 11 correspondences, exist printing opacity to disturb.
The utility model key panel and press-key structure are not limited to the press-key structure that is applied to have a plurality of buttons, also can be applicable to have the press-key structure of single button, this button correspondence arranges a plurality of indicator lights, be placed in one or more button indicator light groups, utilize light shielding block to carry out light isolation to the plurality of indicator light, between a plurality of indicator lights that while avoiding work, button is corresponding, exist printing opacity to disturb.
The foregoing is only preferred embodiment of the present utility model, not in order to limit claim scope of the present utility model, therefore all other do not depart from the equivalence completing under the spirit that the utility model discloses and changes or modify, and all should be contained in scope of the present utility model.
