Abstract
The utility model relates to a button assembly used for scattering light of a button backlight lamp uniformly. The button assembly includes a button support realizing a supporting effect. A touch electronic circuit board is arranged on the button support. The touch electronic circuit board is covered with a button transmitting glass face board. The button assembly is characterized in that a light scattering film used for dimming the light source is arranged between the button support and the touch electronic circuit board and a light emitting assembly is arranged below the button support. By adopting the above technical scheme, the light source is enhanced through the light emitting assembly arranged below the button support. At the same time, light reaches to the touch electronic circuit board through the light scattering film, so that light displayed on the button finally are scattered uniformly.
Description
Technical field
The utility model belongs to button assembly, is specifically related to the button assembly of the balanced astigmatism of a kind of key-press backlight lamp source.
Background technology
On market, most of electronic locks adopt many LED lamp (each button has a LED as backlight) backlight to be convenient to like this reflect by the indication of light source the response condition of button now, are convenient to user and form interaction.But have like this shortcoming, in key area, there will be bright spot, and there will be the bright degree of each button different, if but using a plurality of light sources to solve light source disperses inhomogeneous problem, and its manufacturing cost can significantly rise again.
Summary of the invention
The utility model, in order to solve the technical problem of mentioning in background technology, provides the button assembly of the balanced astigmatism of a kind of key-press backlight lamp source.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
The button assembly of the balanced astigmatism of a kind of key-press backlight lamp source, comprise passive key support, described key support is provided with touch electronic circuit board, on described touch electronic circuit board, cover button printing nonopaque face glass, it is characterized in that: between described key support and touch electronic circuit board, be provided with one deck for the light-diffusing film of fuzzy light source, described key support below is provided with luminescence component.
Described luminescence component comprises key-press backlight lamp plate, tablet and light shield successively, and described tablet and light shield are arranged on the below of the key area of key support.
On described key-press backlight lamp plate, be also provided with successively liquid crystal support, duplicate rows liquid crystal and dustproof sponge, described liquid crystal support, duplicate rows liquid crystal and dustproof sponge are arranged on the below of the liquid crystal region of key support.
The size of described light-diffusing film can cover the key area of key support.
Described button printing nonopaque face glass below is provided with one deck double faced adhesive tape, and described double faced adhesive tape is by key support and the bonding connection of button printing nonopaque face glass.
Adopt after above technical scheme: first by the luminescence component that is arranged on key support below, improve light source, light source arrives and touches electronic circuit board through astigmatic paper simultaneously, make to be finally presented at the light on button, can be dispersed, be provided with again tablet and light shield simultaneously, make the light source of key-press backlight lamp plate can not emit to peripheral region, can not affect the display effect of liquid crystal region, the utility model distinguishing characteristics is to have adopted light-diffusing film, be that light-diffusing film can carry out equilibrium and fuzzy by original light source, make can't occur bright spot on last button out.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In prior art, button assembly is also by a key support, then other parts of keying electronic wiring board and some are set on key support, finally be assembled into a button assembly, key support is roughly divided into installation region, key area and liquid crystal region according to the position of its installation conventionally,, for this prior art, the utility model is specifically made following improvement.
Referring to Fig. 1, the button assembly of the balanced astigmatism of a kind of key-press backlight lamp source, comprise passive key support 1, described key support 1 is provided with and touches electronic circuit board 2, on described touch electronic circuit board 2, cover button printing nonopaque face glass 3, between described key support 1 and touch electronic circuit board 2, be provided with one deck for the light-diffusing film 4 of fuzzy light source, described key support 1 below is provided with luminescence component, described luminescence component comprises key-press backlight lamp plate 5 successively, tablet 6 and light shield 7, described tablet 6 and light shield 7 are arranged on the below of the key area 8 of key support 1, on described key-press backlight lamp plate 5, be also provided with successively liquid crystal support 9, duplicate rows liquid crystal 10 and dustproof sponge 11, described liquid crystal support 9, duplicate rows liquid crystal 10 and dustproof sponge 11 are arranged on the below of the liquid crystal region 12 of key support 1, the size of described light-diffusing film 4 can cover the key area 8 of key support 1, described button printing nonopaque face glass 3 belows are provided with one deck double faced adhesive tape 13, described double faced adhesive tape 13 is by key support 1 and 3 bonding connections of button printing nonopaque face glass, the astigmatic paper of described light-diffusing film 4 concrete employing.
, while double faced adhesive tape is hollow out also, coordinates key area, liquid crystal region and installation region.
For the concrete function of all parts of the present utility model, make following explaining in detail:
1, key-press backlight lamp plate: be to provide back light for button character;
