As shown in fig. 1 to 12, an embodiment of the present application provides an electronic device including a housing 10, a plurality of light sources 20, and a light guide assembly. The housing 10 may be provided with a light-transmitting opening 11. The plurality of light sources 20 may be disposed within the housing 10, and the plurality of light sources 20 may be sequentially arranged along the first direction.

The light guide assembly may include an integral light guide 31 and a separate light guide 32. The integrated light guide 31 is disposed in the housing 10, and at least a portion of the integrated light guide 31 is exposed from the light-transmitting opening 11. For example, the integrated light guide 31 may extend from the inside of the housing 10 to the outside of the housing 10 through the light-transmitting port 11, or the integrated light guide 31 may not extend to the outside of the housing 10, but the integrated light guide 31 may be viewed from the outside of the housing 10 through the light-transmitting port 11. The split light guide 32 may be disposed between the integrated light guide 31 and the plurality of light sources 20, and the split light guide 32 may include a plurality of light guide units 321 sequentially arranged along the first direction. At least part of the side walls of at least part of the light guiding units 321 are provided with reflecting structures, and the reflecting structures are used for reflecting the light rays emitted by the light sources 20 corresponding to the split light guiding pieces 32 to the integrated light guiding pieces 31 so as to prevent the light rays emitted by the corresponding light sources 20 from entering the adjacent light guiding units 321.

The housing 10 of the electronic device is used for mounting and protecting other structures of the electronic device, such as the light source 20 and the light guide assembly. The light-transmitting opening 11 on the housing 10 is used for transmitting light for facilitating the user to check. The light source 20 is used for emitting light, and the light guide assembly is used for guiding the light emitted by the light source 20 so that the light can be transmitted out of the light transmission opening 11.

In the present application, the light guide assembly includes an integral light guide 31 and a split light guide 32, and the split light guide 32 includes a plurality of light guide monomers 321, and the light guide monomers 321 are provided with a reflection structure, so that the reflection mechanism can prevent the light emitted by a certain light source 20 from being transmitted to excessive light guide monomers 321 except the light guide monomers 321 corresponding to the light source 20 when the light source is lighted. Thus, by arranging the split light guide 32 with the plurality of light guide monomers 321 and avoiding light crosstalk through the reflecting structure, the precision in the process of indicating information through light can be improved, and the problem of poor indication precision caused by too wide light propagation of the existing light source 20 is solved.

In order to more clearly understand the effect, the scheme of the present application is compared with the reference scheme. In the reference scheme, the electric quantity indication is carried out through 10 light sources, and a light guide column is arranged on the 10 light sources in a covering mode. When the electric quantity is 10%, the control is carried out to light 1 light source, and the light emitted by the light source is incident to the light guide column and is transmitted out from the light guide column. In this scheme, since the light emitted from the light source has a divergence angle, and the light is diffused in the light guide column, the illuminated length in the light guide column seen by the user may be more than 10% of the total length of the light guide column, which makes the electric quantity indication precision lower. In the embodiment of the present application, as shown in fig. 11, the reflection structure is disposed on the light guiding unit 321 by dividing the light guiding assembly into the integrated light guiding member 31 and the split light guiding member 32. Thus, when the electric quantity remains 10%, the control turns on 1 light source 20, most or all of the light emitted by the turned-on light source 20 can be incident into the corresponding light guide unit 321, a part of the light can be directly incident into the integrated light guide member 31 from the light guide unit 321, and a part of the light can be irradiated to the reflecting structure, and the reflecting structure reflects the light to the integrated light guide member 31. The illuminated portion of the integral light guide 31 thus seen by the user accounts for about 10% of the total length, which results in improved accuracy in indicating the amount of electricity.

In some examples, the light guiding units 321 are disposed in one-to-one correspondence with the light sources 20, and a projection of the light incident surface of the light guiding unit 321 in a second direction covers the light emitting surface of the light source 20, where the second direction is perpendicular to the first direction. The split light guide 32 may include a number of light guide units 321 corresponding to the number of the light sources 20. Thus, most (such as 90% or more) or all of the light emitted from a certain light source 20 is incident into the corresponding light guide unit 321 and cannot leak into the adjacent light guide unit 321, so that the accuracy of the brightness part seen from the light transmitting opening 11 is ensured to be higher, and the indication accuracy is improved.

It will be appreciated that the first direction may be a left-right direction as shown in fig. 10, and the second direction may be an up-down direction in fig. 10.

As can be seen from the above comparison, the scheme of the present application improves the accuracy by avoiding excessive light diffusion, and in order to further improve the effect, in some examples, the light emitting angle of the light source 20 and the interval between the light source 20 and the light incident surface of the light guide unit 321 may be controlled. For example, the light source 20 may be configured to satisfy at least one of the following. .

The light emitting surface of the light source 20 is a single surface, and the light emitting surface of the light source 20 is attached to the light incident surface of the corresponding light guiding unit 321, and the width of the light guiding unit 321 in the first direction is greater than or equal to the width of the light emitting surface of the light source 20.

As shown in fig. 12 or 13, if the interval between the light emitting surface of the light source 20 and the light incident surface of the corresponding light guiding unit 321 is greater than 0, and the light is emitted from at least one surface of the light source 20, the following relationship is satisfied between the light emitting angle and the interval of the light source 20:

The w1 is a width of the light incident surface of the light guide unit 321 corresponding to the light source 20 in the first direction. w2 is the width between the two light rays at the outer end of the light ray emitted from the light source 20 in the first direction. d is the distance between the light emitting surface of the light source 20 and the light incident surface of the corresponding light guiding unit 321, and if the light is emitted from one surface of the light source 20, the emitted surface is the light emitting surface of the light source 20 (for example, the top surface of the light source 20 in fig. 12), or if the light is emitted from multiple surfaces of the light source 20, the light emitting surface is the equivalent surface between two light rays at the outer end of the light source 20 (the surface shown by the dotted line in fig. 13). θ is the angle between the outer light and the second direction, and 2θ is the light emission angle of the light source.

In some examples, a light homogenizing member is provided between the integrated light guide 31 and the split light guide 32 in order to enhance light uniformity. The light homogenizing member is, for example, a light homogenizing film, so that emergent light is more uniform.

In some examples, the light guiding cells 321 include two sides opposing in the first direction, and the reflective structure includes a reflective film that covers the opposing sides. This prevents light from propagating to the adjacent light guiding unit 321 by the reflective film. The reflective film may be an attached reflective film, or may be a film coated on the light guide unit 321 by a coating process (such as vacuum coating or electroless coating), so long as reflection of light can be achieved.

In other examples, the reflective film may be provided on the entire outer peripheral surface of the guide rail cell 321 except for the light incident surface and the light emitting surface. For example, the light guide unit 321 is a quadrangular prism, a pentagonal prism, or other polygonal column, and a reflective film may be provided on the surface other than the light incident surface and the light emitting surface. If the light guide body 321 is a cylinder or the like, a reflective film may be provided on the peripheral surface, which is not limited thereto.

In some examples, as shown in fig. 8 to 10, in order to avoid light leakage, the electronic device further includes a light shielding member 40, the light shielding member 40 having a receiving hole 41, the light shielding member 40 being disposed between the light source 20 and the light guide assembly, and at least portions of the light source 20 and the separate light guide 32 being located within the receiving hole 41. For example, the light shielding member 40 may be made of black silica gel material to prevent light leakage.

For convenient installation, two adjacent light guide monomers 321 are connected by adhesive. Similarly, the split light guide 32 and the integrated light guide 31 may be adhesively connected.

In some examples, as shown in fig. 6 and 7, in order to facilitate the assembly and positioning of the relative positional relationship between the split light guide 32 and the integrated light guide 31, the integrated light guide 31 is provided with a mounting groove into which at least part of the split light guide 32 is embedded.

As shown in fig. 1 to 5, the housing 10 of the electronic device may be divided into an upper case 12 and a lower case 14, and the electronic device further includes a device main body 13, the device main body 13 being disposed between the upper case 12 and the lower case 14. The light source 20 is provided on the apparatus main body 13, and the light guide assembly is provided on the housing 10. For example, the integrated light guide 31 is adhered to the upper case 12 by the double-sided tape 50. The light source 20 is provided on a circuit board which is attached to the apparatus main body 13 by double-sided adhesive tape or the like.

In summary, the light source 20 is, for example, an LED lamp, after the LED lamp emits light, the light enters the corresponding light guiding unit 321, the light incident to the side wall of the light guiding unit 321 is reflected back to the light guiding unit 321 by the reflective film on the side wall, and finally exits to the integrated light guiding member 31, and then exits to the air by the integrated light guiding member 31. This structure can make the final emergent light angle smaller (as shown in fig. 11), that is, even if the light range finally presented on the surface of the integrated light guide 31 is smaller, the electric quantity can be accurately indicated.

The electronic device may be an adapter, controller, etc. of the smart glasses. In addition, the application also provides intelligent glasses which comprise the electronic equipment.
