In the embodiment of the present invention, the light source assembly 40 may be implemented in various manners, one manner is that the light source assembly 40 includes a circuit board and a sub-light source 41 disposed on the circuit board, the sub-light source 41 includes at least one lamp bead, the lamp bead includes but is not limited to a Light Emitting Diode (LED), and the Light Emitting Diode (LED) has the characteristics of fast response speed, low brightness attenuation, small volume, low energy consumption, long service life, and the like, so that the manufacturing cost is reduced on the basis of ensuring the use performance when the light emitting structure is applied, and the LED light source has a high technical maturity, is low in implementation difficulty, and is convenient for wide application. The color of the light emitted by the sub-light source 41 can be set according to different requirements, and can be white, red, yellow, and the like.
One way of realizing the sub-thick-wall unit 32 in the thick-wall light guide 30 is that the sub-thick-wall unit 32 is a block structure, including but not limited to a rectangular block, a cylindrical block, etc., and the main function of the sub-thick-wall unit 32 is to serve as a conducting medium for light, and after the light enters the sub-thick-wall unit 32, the light is totally reflected inside the sub-thick-wall unit 32, so that the light can travel and propagate along the light propagation path of the sub-thick-wall unit 32, and finally is emitted from the light-emitting end 33 of the sub-thick-wall unit 32. The sub-thick-wall unit 32 is made of, but not limited to, a plastic material, including, but not limited to, a PC (Polycarbonate) material, and is made in a manner including, but not limited to, injection molding, and may be made into different shapes according to different requirements, and has a small limitation on the molding and a high degree of freedom in the molding.

The sub-thick-wall unit 32 may also be in a transparent state with colors in a static state, and the colors may be set according to different requirements, such as white, red, yellow, and the like. The sub-thick wall unit 32 may be set in a translucent state according to different requirements. The outer decoration frame 10 and the light shielding frame 20 are made of opaque material.
For realizing better light-emitting effect, still be equipped with the rectification line 331 on the light-emitting end 33 of sub thick wall unit 32, rectification line 331 includes but not limited to for decorative pattern or dermatoglyph, the specification of rectification line 331 can be millimeter level specification, in order to form relatively tiny line, make the light-emitting direction concentrate more, the light-emitting is more homogenization, light is through the correction of rectification line 331, can effectively reduce the facula of light-emitting, make the light-emitting effect even and high-efficient, promote the illumination quality of light-emitting structure.
Referring to fig. 5, 6 and 7, in some embodiments of the present application, the thick-walled light guide 30 is implemented in such a manner that the connection plates 31 are respectively connected to the circumferential outer walls of the sub-thick-walled units 32 and divide the sub-thick-walled units 32 into the light exit section 321 and the light entrance section 322. The light-emitting section 321 is disposed in the light-emitting hole 11, and one end of the light-emitting section 321 away from the light-entering section 322 is the light-emitting end 33. The light input section 322 is disposed in the light input hole 21, and one end of the light input section 322 away from the light output section 321 is the light input end 34. The sub-thick-wall units 32 are connected together by the connection plate 31 so that the thick-wall light guide 30 forms an integral structure for subsequent assembly and the like. The connecting plate 31 may be made of the same material as that of the sub-thick-wall units 32, in order to reduce the light transmission through the sub-thick-wall units 32 at adjacent positions of the connecting plate 31, the thickness of the connecting plate 31 is much smaller than that of the sub-thick-wall units 32, the thickness of the connecting plate 31 may be below 1/10 of that of the sub-thick-wall units 32, and the connecting plate 31 has a thin-wall structure compared with the sub-thick-wall units 32, so that the light transmission through the connecting plate 31 can be effectively reduced.
In some embodiments of the present application, one way to connect the connecting plate 31 and the sub-thick-wall unit 32 is to integrally form the connecting plate 31 and the sub-thick-wall unit 32. The connecting plate 31 and the sub-thick-wall unit 32 may be made of plastic, and the connecting plate 31 and the sub-thick-wall unit 32 may be made of the same material or different materials, and are integrally opened, and are injection-molded by a single mold to finally form the thick-wall light guide 30. The connection strength between the connecting plate 31 and the sub-thick wall unit 32 can be ensured by the integrally formed structure, and secondary connection processes are reduced, so that the manufacturing cost is reduced, meanwhile, the manufacturing process is simple, and the production efficiency can be effectively improved.
In some embodiments of the present application, another connection manner of the connection plate 31 and the sub-thick-wall unit 32 is that the connection plate 31 and one of the light-entering section 322 and the light-exiting section 321 are an integrally formed structure, and the light-entering section 322 and the light-exiting section 321 are separate structures. The light-in section 322 and the light-out section 321 of the split structure are more convenient for the installation of the thick-walled light guide 30, the exterior trim frame 10 and the light-shielding frame 20, the light-in section 322 can be first installed on the light-shielding frame 20 to form a first part, then the light-out section 321 is installed on the exterior trim frame 10 to form a second part, and then the two parts are assembled together to form the thick-walled light guide 30. To facilitate the propagation of light, the surface of the light-entering section 322 connected to the light-exiting section 321 is a plane, so as to reduce the refraction of light and reduce the light loss.
To further reduce light leakage from the slits, in some embodiments of the present application, the outer sidewall of the light exit section 321 is disposed against the inner wall of the light exit hole 11. The outer side wall of the light incident section 322 is closely attached to the inner wall of the light incident hole 21. In this way, while the connection stability between the thick-wall light guide member 30 and the exterior plate and the light shielding plate can be enhanced, the gap between the thick-wall light guide member 30 and the exterior plate and the light shielding plate can be reduced, thereby reducing the probability of light leakage from the gap, and improving the isolation effect of the exterior bezel 10 and the light shielding frame 20, thereby enabling each sub thick-wall unit 32 to independently realize light emitting operation, reducing the light leakage phenomenon between adjacent sub thick-wall units 32, and further being capable of realizing that each sub thick-wall unit 32 can independently conduct light outwards on the premise of considering cost and structural reliability, thereby displaying the lighting form of various patterns.
With continued reference to fig. 6, in order to further improve the light-shielding effect of the light-shielding frame 20, in some embodiments of the present application, the length of the light-entering section 322 is greater than the length of the light-exiting section 321. According to the requirement of light propagation, the sub-thick-wall unit 32 has a certain thickness, that is, the light-entering section 322 and the light-exiting section 321 have a certain length relative to the connecting plate 31, and the depths of the light-entering hole 21 and the light-exiting hole 11 are matched with the lengths of the light-entering section 322 and the light-exiting section 321. The light emitted from the sub-light source 41 enters the sub-thick-wall unit 32 through the light-entering section 322, and light leakage is more likely to occur. Therefore, the light incident section 322 is set to be longer, so that the depth of the light shielding hole is also deeper, the light shielding range of the light shielding frame 20 is increased, and light leakage of light at the stage of entering the sub thick-wall unit 32 is reduced. Of course, in the embodiment of the present application, the length of the light-entering section 322 may also be set to be the same as the length of the light-emitting section 321, or the length of the light-emitting section 321 may also be greater than the length of the light-entering section 322.
In order to further reduce the light leakage, in some embodiments of the present application, the light incident end 34 is lower than the surface of the light-shielding frame 20 relative to the surface of the light-shielding frame 20 opposite to the exterior frame 10. In this arrangement, the light incident end 34 is located inside the light incident hole 21, and the light enters the light incident hole 21 and then enters the sub light incident end 34. Through the sheltering from of the inner wall of going into unthreaded hole 21, can prevent effectively that light from propagating to the sub thick wall unit 32 of other adjacent positions, can play the effect that prevents the light leak better. Further, the light source module 40 abuts against the light shielding frame 20, and the sub-light sources 41 are located in the light incident holes 21. Of course, the end surface of the light incident end 34 may be flush with the surface of the light shielding frame 20 opposite to the exterior frame 10 according to different installation requirements. The end face of the light-emitting end 33 may be flush with a surface of the outer bezel 10 facing away from the light frame, or protrude from the surface of the outer bezel 10, or be lower than the surface of the outer bezel 10 according to different requirements.
