Description
Technical Field
[0001] The utility model relates to the technical field of automobile accessories, in particular to a light guide light splitting structure for illuminating multiple beacons with a single light source. Background Art
[0002] Existing automobiles typically control various functions through manual controls or touch panels. Touch controls are more advanced and represent a major future trend. However, in practice, touch controls are less stable than manual controls, with poor controllability and sensitivity. This can lead to excessive driver distraction and safety concerns, especially during driving. Therefore, manual controls, such as buttons or knobs, remain the most popular method for controlling various vehicle functions in the current market.
[0003] To ensure drivers can clearly identify control elements during nighttime driving, automakers often install light sources behind each element. These light-transmitting areas are patterned with different patterns on the element or on the housing it is mounted on, allowing the light to illuminate each beacon, making it easier to distinguish. However, this approach requires multiple light guides and LEDs to illuminate multiple beacons. This structure requires multiple internal fixtures at multiple locations, resulting in a complex structure, space-consuming space, and high manufacturing costs. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings and deficiencies of the prior art and to provide a light guide light splitting structure capable of illuminating multiple beacons with a single light source.

[0009] As an optimal technical solution of the present utility model, a partition is provided in the base and the partition divides the base into an upper chamber and a lower chamber. The positioning part is fixed or integrally formed on the partition. A part of the positioning part extends to the upper chamber to form a positioning block A, and the other part extends to the lower chamber to form a positioning block B.

DETAILED DESCRIPTION
[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.
[0024] The specific embodiments of the present utility model are described below with reference to the accompanying drawings.
[0025] like Figure 1-6The light guide light splitting structure shown is a single light source that illuminates multiple beacons, including a shell 1, an operating member 2 arranged on the shell 1, and a plurality of transparent beacons 3 arranged at the position corresponding to the operating member 2. A PCB board 4, an LED 5 electrically connected to the PCB board 4, and a light guide 6 corresponding to the position of the LED 5 are arranged in the shell 1. The light guide 6 includes a light guide column 7 and a plurality of light guide parts 8 extending from the upper end of the light guide column 7 to the surrounding areas. An installation point for installing the light guide column 7 is provided in the shell 1. The plurality of transparent beacons 3 respectively correspond to the light guiding surfaces at the upper ends of the plurality of light guiding parts 8. The light guiding surfaces cover each transparent beacon 3. The lower end of the light guide 6 corresponds to the LED 5. The transparent beacon 3 in this embodiment represents a sign or pattern that can form a transparent area. The cover 11 and the base 10 are made of opaque materials. In this embodiment, the operating member 2 can be a knob or a button, etc.
[0026] The light guide 6 of the present application includes a light guide column 7 and multiple conduit portions diverging from the upper end of the light guide column 7. The light guiding path of the light guiding surface depends on the arrangement of the light-transmitting beacons 3, and the light guiding surface needs to cover the light-transmitting beacons 3 (that is, the size of the light guiding surface must be larger than the light-transmitting beacons 3) so that the light source can evenly penetrate each light-transmitting beacon 3. Only one mounting point needs to be set in the shell 1 to fix the light guide column 7. Compared with the traditional method of installing multiple light guides 6 at multiple points, the present application optimizes the internal space, saves occupied space, achieves miniaturization, and reduces manufacturing costs. The light emitted by the light-emitting surface 9 is not generated by itself, but is light transmitted through the light guide column.
[0027] Each light-guiding surface is provided with a plurality of light-emitting surfaces 9 along the direction of its respective light-guiding path, and the structure of the light-emitting surface 9 branched by the light-guiding body 6 is designed according to the brightness requirements of different light-transmitting beacons 3. There is a height difference between two adjacent light-emitting surfaces 9, and each light-emitting surface 9 covers the corresponding light-transmitting beacon 3. The height of each light-emitting surface 9 arranged from the inside to the outside of each light-guiding surface gradually increases, so that the light source diverges more evenly, ensuring that the light penetrates each light-transmitting beacon 3.
[0028] The housing 1 includes a base 10 and a cover 11. The light-transmitting beacon 3 and the operating member 2 are arranged on the cover 11. The PCB board 4 is installed in the base 10. A positioning portion 12 is provided in the base 10 and a positioning groove 13 for inserting the light guide column 7 is opened on the positioning portion 12.
[0029] A partition 14 is provided in the base 10 and the partition 14 divides the base 10 into an upper chamber 15 and a lower chamber 16. The positioning portion 12 is fixed or integrally formed on the partition 14. A portion of the positioning portion 12 extends to the upper chamber 15 to form a positioning block A17, and the other portion extends to the lower chamber 16 to form a positioning block B18. A light guide port 19 is provided on the positioning block B18, and the light guide port 19 corresponds to the LED 5 of the PCB board 4.
[0030] The upper end of the positioning block A17 is provided with limiting notches 20 located on both sides of the positioning groove 13, and limiting blocks 21 are provided on both sides of the light guide column 7 to cooperate with the limiting notches 20. It is only necessary to align the limiting blocks 21 of the light guide column 7 with the limiting notches 20 of the positioning groove 13 and insert them. After the light guide column 7 is installed, its lower end just corresponds to the LED5 on the PCB board 4.
[0031] The light guide port 19 is provided on the side wall of the positioning block B18, and the PCB board 4 is vertically installed in the lower chamber 16 of the base 10. With this arrangement, the width of the housing 1 is reduced, thereby achieving miniaturization.
[0032] As a preferred technical solution of the present invention, an opening 22 communicating with the lower chamber 16 is provided at the bottom of the base 10 , and a connector 23 located at the opening 22 is electrically connected to the PCB board 4 .
[0033] The side wall of the base 10 is provided with an installation window 24 and a panel 25 for closing the installation window 24. Blocks 26 are provided on both sides of the panel 25. Card holes 27 for engaging with the block 26 are provided on both sides of the base 10 to facilitate the pre-assembly of internal accessories, such as electronic components such as the PCB board 4. After the assembly is completed, the block 26 of the panel 25 can be aligned with the card hole 27 of the base 10.
[0034] The lower part of the panel 25 extends toward the inside of the opening 22 to form a clamping portion 28, which abuts against the side wall of the joint 23 to prevent the joint 23 from loosening and make the connection more stable. Of course, a certain gap can also be left so that the clamping portion 28 does not abut against the joint 23.
[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
