Along with the maturity of wireless charging technology, more and more on-vehicle cell phone stand still has the wireless function of charging, and on-vehicle cell phone stand also is a cell-phone wireless charging support promptly.

Although the current wireless charging support for the vehicle-mounted mobile phone has the functions of fixing the mobile phone and wirelessly charging, and is multifunctional, the current wireless charging support for the vehicle-mounted mobile phone cannot meet the variable decoration requirements in the vehicle. In order to meet decoration requirements in an automobile, some mobile phone wireless charging supports in the prior art are modified by adopting a edging process, but the automobile is more and more changed into an electronic product nowadays, and the unchanged edging effect of the mobile phone wireless charging support is more and more difficult to match with the changeable interior trim style of the automobile.

On the other hand, the automobile atmosphere lamp is provided in the prior art, the decorative atmosphere inside the automobile is adjusted through light, but the atmosphere lamp has no practical value, and the market prospect is not large. Although the problem that the atmosphere lamp is not practical can be solved by installing the atmosphere lamp on the mobile phone wireless charging support, the automobile atmosphere lamps still have the following problems: partial atmosphere lamps are uneven in light emission and easy to dazzle, and driving is affected. In contrast, in the prior art, it is proposed to use a light guide fiber as a light emitting element of an atmosphere lamp, and although this scheme can achieve uniform light emission, the light guide fiber is not easy to fix, and cannot meet the complicated and variable shape requirements of a wireless charging support of a mobile phone.

The wireless support that charges of domestic cell-phone also has similar problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a wireless support that charges of cell-phone makes the wireless support that charges of cell-phone possess the decorative effect who rivals the beautiful atmosphere lamp under the condition of hardly incremental cost.

The utility model provides an above-mentioned technical problem adopted technical scheme as follows: the wireless charging support comprises a shell, a wireless charging coil and a light source, wherein the wireless charging coil and the light source are arranged in the shell, at least one part of the shell is provided with a light-emitting part consisting of a hard transparent plastic part, and the light-emitting part receives at least part of light rays emitted by the light source and uniformly emits the light rays; the light-emitting part is formed into a specified shape which can be smoothly matched and connected with other parts on the shell through an injection molding process, wherein at least part of the light-emitting part is a strip shape which can be matched with the outer contour of the mobile phone wireless charging support; at least one of the color and the luminous intensity of the light source can be dynamically changed, so that the light emergent part can be used as a part of the shell, and meanwhile, the uneven light emitted by the light source can be converted into uniform light with a specified shape and then emitted, and the decorative effect is changed.

The light emergent part is a part of the shell, or is a rim arranged on the edge of the shell, or is an applique arranged on the shell (namely various designs embedded on the shell).

The utility model has the advantages that: the light-emitting part can convert the uneven light emitted by the light source into the uniform light with the specified shape and then emit the uniform light, so that the mobile phone wireless charging support has the decorative effect of an atmosphere lamp; the problem that dazzling is easily caused by uneven original light emitted by the light source is solved, the special effect that the light source emits light in a point shape and the light emitting part illuminates in a piece is achieved, and the number of the light sources is greatly saved (in the prior art, a plurality of light sources are required to form an array when the light sources illuminate in a piece).

When the light emergent portion is a part of the shell, the light emergent portion is different from the prior art only in materials, processes and structures; and generally speaking the wireless support that charges of cell-phone all has the display lamp that charges, so the light source is also not the utility model discloses newly-increased part, including the power be the power of charger self again, consequently the utility model discloses what materials do not increase, therefore the utility model discloses compare with the wireless support that charges of current cell-phone, but the incremental cost under the condition that has increased the atmosphere lamp effect. Furthermore, the light-emitting part of the present invention is manufactured by injection molding as a part of the housing, so that it can be installed and connected with other parts like a common conventional part, or can be connected mechanically by a conventional process such as clamping, screwing or riveting, and does not have the problems of difficult installation, difficult fixation, unsmooth matching with other parts, etc. of the optical fiber.

The non-total reflection surfaces are distributed discretely, so that light rays are continuously transmitted out of the light-emitting surface through reflection of the light splitting surface along the light conduction path, and the effect of uniformly emitting light on the whole conduction path is achieved.

The non-total reflection area can be formed by a tooth-shaped or convex-concave area which is injected on the light splitting surface, when the mode is adopted, the light splitting surface can be formed at one time in the injection molding process, no additional process is needed, no additional material is needed, and only a proper injection mold needs to be designed.

Or the non-total reflection area is formed by arranging a light reflecting substance on the light splitting surface. When the scheme is adopted, the total reflection areas can be various and respectively correspond to different reflecting substances, and each reflecting substance can reflect light with different wavelengths. Thus, when the color of the light changes, the emergent pattern effect changes along with the change, and a more fantastic effect is formed.

The light outlet part further comprises a plate-shaped part or a special-shaped part; the profile comprises at least one of: has a shape of a bent portion, a shape with a convex-concave surface, and a shape with a thick-thin surface. The special-shaped support can be more suitable for the changeable style of the charging support.

The light-emitting parts 5 and 6 are provided with a light-emitting surface, a light-splitting surface and a light-entering surface, the light-splitting surface comprises a plurality of non-total reflection areas and total reflection areas which are regularly distributed, the non-total reflection areas (such as adopting a light tooth micro-reflection structure) are non-uniformly distributed, but the distribution is regular, and the front part is thin and the back part is dense according to the advancing direction of light, so that the brightness of the whole light-emitting part is ensured to be uniform, and the non-total reflection areas at the back part are dense because the light intensity at the front part is slightly larger. The light-emitting surface is totally reflected relative to incident light and light reflected by the total reflection area in the light splitting surface, but is refracted relative to light reflected by the non-total reflection area in the light splitting surface, so that after the light emitted by the light source enters through the incident surface, a part of the light is conducted forwards by utilizing the total reflection principle, and the other part of the light is separated by the light splitting surface and is emitted from the light-emitting surface, so that the light is gradually distributed and emitted from each part of the light-emitting part to form a uniform light-emitting band. After light emitted by the light source enters the light emergent part from the light incident surface, the part falling on the total reflection area is forwardly transmitted by utilizing the total reflection principle, but the part falling on the non-total reflection area is partially reflected to the light emergent surface by the light splitting surface and is transmitted out. Therefore, the mobile phone wireless charging support can emit uniform light from the light emitting part, the atmosphere lamp effect of the mobile phone wireless charging support is improved on the basis of wireless charging, and the ornamental value is improved; meanwhile, light emitted by the light source enters the light emergent portion from the light incident surface and is reflected by the different light splitting surfaces in sequence and then is uniformly dispersed and emitted from the light incident surface gradually, so that the light is emitted more uniformly, and the light emitting effect is better.

The light source comprises a first light source 21, the light guide strip 5 has a total reflection turning part 52, the light emitting surface 51, a light splitting surface 53 and a light entering surface 54, the light emitted by the first light source enters the light guide strip 5 from the light entering surface 54 on the light guide strip 5, after being totally reflected to the light splitting surface 53 on the light guide strip by the total reflection turning part 52 on the light guide strip 5, a part of light is conducted forwards by using the total reflection principle, the other part of light is separated by the light splitting surface 53 and emitted from the light emitting surface 51, so that the light is gradually emitted from each part of the light emitting part in a distributed manner, and a uniform light emitting band is. The color and luminous intensity of the light source can be dynamically changed or adjusted, so that the light emergent part can be used as a part of the shell, can convert uneven light emitted by the light source into uniform light with a specified shape and then emits the uniform light, and has a changeable decorative effect

The light emergent portion may be provided in a special-shaped structure, such as a shape having a bent portion, a shape having a concave-convex variation in surface, and a shape having a variation in thickness, in order to smoothly fit and connect with other portions on the housing without leaving a gap.

Since only part of the incident light that is not totally reflected is transmitted through the light exit surface 51, and the rest of the light (the light that does not fall into the totally non-reflective region) is still transmitted forward along the light guide strip, only part of the light is transmitted by the points a and B. Therefore, the density and distribution of the points A and B are reasonably set, and the quantity of emergent light at different parts on the light guide strip can be controlled.
