Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
As Figure 1-3, a kind of area source formula ultrathin type button, including housing 1 ringwise, housing 1 is provided with installation
Mesopore, is sequentially overlapped along top to bottom direction in housing 1 and has the letter plate 2 of light-permeable pattern, the driving member of light-permeable
3, lightguide 4, the printed circuit board 5 with electronic component and cover plate 6；
Printed circuit board 5 is provided with light source component 51 and switch 52, light source component 51 at least three away from the side of cover plate 6
Individual, the edge that multiple light source components 51 are positioned at printed circuit board 5 is uniformly distributed, and light source component 51 is the LED that side is luminous,
The center of LED horizontally toward printed circuit board 5.
During use, the light of LED does not shine directly on lightguide 4, but is horizontally disposed with, the light of each LED
All being irradiated to the center position of printed circuit board 5, afterwards, lightguide, by light is carried out secondary distribution, has changed area source into
Luminescence, and then make light source more uniform.
Wherein, lightguide 4 is to be printed with the light guiding film of circular site, transparent plastic Cylinder, first enter into the table of light
Face silk-screen or laser engraving circular site.
Switch 52 is located at the center of printed circuit board 5, the central inner surface of lightguide 4 and the central outer surface switching 52
It is overlapped mutually.
Ultrathin button, is limited by thickness, and its inner space is less, in order to reasonably utilize space structure, will open
Closing 52 and be arranged on middle part, both convenient switch 52 action triggering switch 52, meanwhile, space utilization is more reasonable.
Switch 52 is metal dome, and the top of metal dome is provided with in silica gel head, the outer surface of cupular part of silica gel head and lightguide 4
Endocardial surface fits.
Accordingly, the thinner thickness of ultrathin button, therefore, its service life receives impact, wherein, in order to improve product
Service life, switch 52 employing metal dome structure, have contact steadily, conduction is strong, resilience is stable, feel is all good
Feature, meanwhile, arranges silica gel head on the beginning, and lightguide 4 covers on silica gel head, and so thickness of switch 52 can be accomplished very
Thin, the life-span will not reduce because of switch 52 thinning being affected.
Area source formula ultrathin type button, also includes that installing rack 7, installing rack 7 are connected with housing 1.Button is carried out by installing rack 7
Installing, owing to button is relatively thin, the intensity that can bear is relatively low, is not easy to install, therefore, is arranged on by button on installing rack 7, enters one
The assembling to button of the convenience of step.
Installing rack 7 is provided with installing hole, and installing hole is provided with the claw extended to center position, and the sidewall of housing 1 sets
There is the draw-in groove cooperated with claw.
Wherein, the sidewall of housing 1 arranges the draw-in groove of multiple inclination, installing rack 7 is provided with and matches with draw-in groove
The claw of inclined shape, during installation, housing 1 is inserted by the front of the installing hole on installing rack 7, after insertion, claw along with
The movement of housing 1 snaps onto in draw-in groove, thus completes fixing housing 1, i.e. button.Arranging multiple draw-in groove, multiple draw-in grooves are indulged
To arrangement, the insertion depth of scalable button.
The side that cover plate 6 is relative with printed circuit board 5 is provided with multiple groove.
Arranging multiple electronic component on printed circuit board 5 plate, wherein, its upper surface only arranges light source component 51 and switch
52, other relevant electronic components are arranged on the lower surface of printed circuit board 5, therefore, arrange multiple groove on cover plate 6, can
For accommodating the electronic component on printed circuit board 5, and then space can be saved.
Time specifically used, pressing letter plate 2, letter plate 2 drives driving member 3 descending, and driving member 3 triggers printed circuit board 5
On switch 52, function triggers, and letter plate 2 and driving member 3 reset, and tactile depressing action completes.The light that LED sends is through leaded light
After device 4, through driving member 3 and letter plate 2, reaching to light the purpose of pattern on letter plate 2, what each LED sent is point source,
By lightguide 4 secondary light-distribution, be converted to surface source luminescence so that the pattern illumination effect on letter plate 2 is uniform, button pattern
Luminescence Uniformity just can be effectively improved, and then improves the aesthetic property of button.
Know-why of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
By novel principle, and the restriction to this utility model protection domain can not be construed to by any way.Based on explanation herein,
Those skilled in the art need not pay performing creative labour can associate other detailed description of the invention of the present utility model,
Within these modes fall within protection domain of the present utility model.
