Abstract
The utility model discloses a touch button backlight light guide device. The touch button backlight light guide device comprises a casing, a panel, a light guide sheet and a light emitting plate, wherein the panel is buckled on an open port of the casing, a lower portion of the panel is provided with multiple touch button positions, the light guide sheet and the light emitting plate are mounted at a lower portion of an inner chamber of the casing in order, the light guide sheet is provided with multiple light reflection faces, the light emitting plate is provided with multiple LED lamps, the multiple light reflection faces on the light guide sheet are just opposite to the multiple LED lamps on the light emitting plate, and the multiple touch button positions at the lower portion of the panel are just opposite to the multiple light reflection faces on the light guide sheet. The touch button backlight light guide device is characterized in that a light guide plate is additionally arranged, the light guide plate has an inclined plane which can realize light refraction, so the multiple touch button positions at the lower portion of the panel are made to be opposite to the multiple light reflection faces on the light guide sheet in a staggered mode, and thereby the light guide sheet can be mounted at a lower position, and assembly is more convenient.
Description
Technical field
The utility model relates to a kind of mobile phone, particularly relates to a kind of touch key-press guiding device backlight.
Background technology
At present, existing smart mobile phone comprises panel, casing, circuit board, luminous plaque, and circuit board and luminous plaque all are installed in the casing, and luminous plaque is positioned at the bottom of chassis cavity, so that relative with the touch key-press position on the panel.But because the size of circuit board is bigger, taken most of space of chassis cavity, light-emitting diode on the luminous plaque will be installed in lower position, and the touch key-press position on the corresponding panel also will be arranged on lower position, and this arranges for panel touch key-press position and has brought great trouble.
The utility model content
The purpose of this utility model is to provide a kind of convenient touch key-press guiding device backlight that assembles.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of touch key-press guiding device backlight, and it comprises casing, panel, light guide sheet, luminous plaque; Described panel snaps onto on the open port of casing, and the bottom of panel is provided with a plurality of touch key-presss position; Described light guide sheet, luminous plaque are installed in the chassis cavity bottom successively, and light guide sheet is provided with a plurality of reflective surfaces, luminous plaque is provided with a plurality of LED lamps, a plurality of reflective surfaces on the described light guide sheet are positive relative with a plurality of LED lamps on the luminous plaque, and a plurality of touch key-presss position of panel bottom is relative with a plurality of reflective surfaces on the light guide sheet.
A plurality of touch key-presss position of described panel bottom is relative with a plurality of reflective surface dislocation on the light guide sheet.
Described light guide sheet is made of body and a plurality of boss; Described a plurality of boss is equidistant, fixed interval is in a side of body, and the upper surface of boss is a low inside and high outside inclined-plane as reflective surface, and is higher with the body junction, lower away from the body junction.
Described panel bottom is provided with four touch key-press positions, and light guide sheet is provided with four reflective surfaces, and luminous plaque is provided with four LED lamps.
After adopting such scheme, because the utility model is set up a light guide plate, this light guide plate has an inclined-plane, this inclined-plane can be with light refraction, make that a plurality of touch key-presss position of panel bottom is relative with a plurality of reflective surface dislocation on the light guide sheet, make light guide sheet can be installed in lower position, assemble convenient.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is three-dimensional exploded view of the present utility model;
Fig. 2 is assembling schematic diagram of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, the utility model is a kind of touch key-press guiding device backlight, and it comprises casing 1, panel 2, light guide sheet 3, luminous plaque 4.
Described panel 2 snaps onto on the open port of casing 1, and the bottom of panel 2 is provided with four touch key-press positions 21.
Described light guide sheet 3, luminous plaque 4 are installed in casing 1 inner chamber bottom successively, and luminous plaque 4 is resisted against casing 1 inner chamber lower end edge 11.
Described light guide sheet 3 is made of body 31 and four boss 32; Described a plurality of boss is 32 equidistant, fixed interval is in a side of body 31, the upper surface of boss 32 be one low inside and high outside as reflective surface inclined-plane 33, four inclined-planes 33 on four boss 32 constitute four reflective surfaces 33, and itself and body 31 junctions are higher, and are lower away from the body junction.
Described luminous plaque 4 is provided with four LED lamps 41, four reflective surfaces 33 on the described light guide sheet 31 are relative with four LED lamps, 41 fronts on the luminous plaque 4, four touch key-press positions 21 of panel 2 bottoms are relative with four reflective surfaces, 33 dislocation on the light guide sheet 3, namely, the upright position dislocation of four reflective surfaces 33 of four reflective surface 33 horizontal levels on the horizontal level of four touch key-press positions 21 of panel 2 bottoms and the light guide sheet 3 on, 21 upright positions, four touch key-press positions of panel 2 bottoms and the light guide sheet 3 is relative.
Emphasis of the present utility model just is: set up a light guide sheet.
The above, it only is the utility model preferred embodiment, the quantity of reflective surface can be decided according to needs on the light guide sheet, so can not limit the scope that the utility model is implemented with this, the i.e. equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
