Description
Technical Field
The utility model relates to an electronic terminal equipment field especially relates to a lid color-changing device behind electronic terminal equipment.
Background
The back cover of the electronic terminal equipment is a peripheral accessory arranged on the back of the electronic terminal equipment and mainly has the functions of protection, decoration and the like. The lid behind current electronic terminal equipment either uses monoblock metal raw materials to contain the direct integrated into one piece processing of center, or uses plastic injection moulding. Because metal and plastic are light-tight, the existing electronic terminal equipment cannot emit light in a large area by utilizing the rear cover, only can locally stick an LED light source, emit light at the locally hollow logo position, and cannot achieve the effect of overall light emission; or nano-imprinting is carried out on the surface of the rear cover, so that the rear cover has a color change effect, but the function of changing color gradually can be realized only by external illumination, and the effect of autonomous color change cannot be achieved.
Accordingly, the prior art is deficient and needs improvement.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough of prior art, providing a lid color changing device behind electronic terminal equipment, making the back lid independently discolour to reach comprehensive luminous effect.
The technical scheme of the utility model as follows: the utility model provides a lid colour change device behind electronic terminal equipment, includes: transparent glass apron, establish transparent glass apron inboard light guide plate and establishing the light source of light guide plate one side, the light source includes FPC and welds a plurality of RGB lamps on FPC.
Furthermore, diffusion particles are arranged in the light guide plate.
Further, the light guide plate is provided with two layers of shading glue, wherein one layer of shading glue is a black and white double-sided glue and covers the front position of the RGB lamp and the other three sides of the light guide plate, the white side faces the light guide plate, and the other layer of shading glue is a black and black double-sided glue and covers the whole light source and the other three sides of the light guide plate.
Furthermore, the reflecting surface and the light-emitting surface of the light guide plate are mirror surfaces.
Furthermore, camera openings are formed in corresponding positions of the rear cover bottom plate, the transparent glass cover plate and the light guide plate.
Further, the camera hole is located in the upper left corner or the upper right corner of the light guide plate.
Adopt above-mentioned scheme, the utility model discloses a clear glass apron, the apron inboard sets up light guide plate and light source and forms the luminous display area of back lid, and the display area sends different display effects according to different functions around making equipment. Meanwhile, through line control, different colors of light are emitted according to different instructions, so that the transparent rear cover emits colorful light, the light emitting color and mode can be freely set, and the light can be emitted in cooperation with incoming call and information notification.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 3, the present invention provides a rear cover color-changing device for an electronic terminal, including: the light source module comprises a transparent glass cover plate 11, a light guide plate 12 arranged on the inner side of the transparent glass cover plate 11, and a light source 13 arranged on one side of the light guide plate 12, wherein the light source comprises an FPC32 and a plurality of RGB lamps 31 welded on the FPC 32. The transparent glass cover plate 11 plays a role of protection and fixation, and then, light of different colors on the light guide plate 12 can be seen more intuitively.
The light guide plate 12 is internally provided with diffusion particles, the light guide plate 12 conducts light rays to form a point light source emitted by the RGB lamp 31 into a surface light source, the diffusion particles are arranged in the light guide plate 12 and added into raw materials during injection molding of the light guide plate, and the light emitted by the RGB lamp 31 is uniformly scattered due to the existence of the diffusion particles to fill the whole light guide plate 12. The light guide plate 12 is provided with two layers of shading glue, wherein one layer of shading glue is a black-white double-sided adhesive tape 21 and covers the front position of the RBG lamp 31 and the other three side edges of the light guide plate 12, the white side faces the light guide plate 12, the white side reflects light, and the black side plays a role in shading; the other layer of light-shielding adhesive is black double-sided adhesive 22, which covers the whole light source 13 and the other three sides of the light guide plate 12, and covers the light source 13 and the light on the other sides and can be adhered and fixed with the transparent glass cover plate 11. The reflection surface and the light exit surface of the light guide plate 12 are mirror surfaces. The corresponding position all is provided with camera trompil 14 on transparent glass apron 11 and the light guide plate 12 to hold the camera, increase glass apron light show area, in this embodiment, camera trompil 14 is located the upper left corner or the upper right corner of light guide plate 12.
The FPC32 forms a wiring for connection with electronic terminal equipment. And receiving different instructions of the electronic terminal processor, so that the RGB lamp 31 emits light with different colors, and the light guide plate 12 presents rich colors, thereby realizing the color change function of the rear cover of the electronic terminal equipment. The back cover is different from the existing back cover with the nano-imprinting surface, and the color-changing function can be realized only under the condition of external illumination, which belongs to active color change.
The utility model is suitable for a various mobile electronic terminal equipment.
To sum up, the utility model discloses a transparent glass apron, the apron inboard sets up light guide plate and light source and forms the luminous display area of back lid, and the display area sends different display effects according to different functions around making equipment. Meanwhile, through line control, different colors of light are emitted according to different instructions, so that the transparent rear cover emits colorful light, the light emitting color and mode can be freely set, and the light can be emitted in cooperation with incoming call and information notification.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
