[0020] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings and described in detail.

[0021] like Figure 1As shown, an embodiment of the present invention provides a light-emitting decorative frame 100 , which is installed on a front bumper 200 of a vehicle. A grille 300 is also provided on the front bumper 200 , and the light-emitting decorative frame 100 is arranged around the grille 300 .

[0022] like Figure 2 and Figure 3 As shown, the light-emitting decorative frame 100 includes a bracket 110, a plurality of light guide sheets 120 and a light-transmitting mask 130. The bracket 110 is annular, the plurality of light guide sheets 120 are fixed on the bracket 110 and are evenly arranged along the circumference of the bracket 110, and the light-transmitting mask 130 is fixed on the bracket 110 and covers the outer sides of the plurality of light guide sheets 120, so that the plurality of light guide sheets 120 are located between the light-transmitting mask 130 and the bracket 110. The light-transmitting mask 130 can play a role of transmitting light on the one hand, and can play a role of protecting the plurality of light guide sheets 120 on the other hand.

[0023] like Figure 4 As shown, a plurality of light-emitting components 140 may also be provided on the bracket 110, and the plurality of light-emitting components 140 correspond one-to-one to the plurality of light guide plates 120. The light-emitting components 140 are used to emit light to the light guide plates 120. The light guide plates 120 convert the light emitted by the light-emitting components 140 from a line light source into a surface light source, and make the light of the surface light source be emitted from the light-transmitting mask 130. Since there are a plurality of light guide plates 120 and they are evenly arranged along the circumference of the bracket 110, the evenly distributed light-emitting surface inside the light-transmitting mask 130 can be seen from the outside of the light-transmitting mask 130, thereby presenting a matrix-like light-emitting effect.

[0024] The bracket 110 can be installed on the front bumper 200 and disposed around the grille 300 , so that the light-emitting decorative frame 100 plays a role of light decoration for the front bumper 200 .

[0025] In some embodiments, each light guide sheet 120 is provided with a microstructure texture on its surface, and the light guided by the light guide sheet 120 is diffusely reflected by the microstructure texture surface, so as to emit light on the microstructure texture surface to achieve a special light-emitting effect. The microstructure texture can be laser dots, frosted treatment, etc. The light guide sheet 120 can be made of PMMA (polymethyl methacrylate) or PC (polycarbonate) material. The microstructure texture can be provided on the top surface of the light guide sheet 120 opposite to the light-transmitting portion 131, and can also be provided on the top surface and the side surface of the light guide sheet 120 at the same time.

[0026] In some embodiments, the light-transmitting mask 130 may include a light-transmitting portion 131 and a light-impermeable portion 132, wherein the light-transmitting portion 131 is opposite to the top surface of each light guide sheet 120, and the light-impermeable portion 132 is fixedly connected to the bracket 110 (for example, bonded), so that the light emitted by the light-emitting component 140 can be guided by the light guide sheet 120, then emitted from the top surface of the light guide sheet 120 and pass through the light-transmitting portion 131, thereby forming a matrix-type light-emitting effect; since the side surfaces of each light guide sheet 120 are opposite to the light-impermeable portion 132, they cannot pass through the light-transmitting mask 130, thereby preventing the light from emitting from the side surfaces of the light-transmitting mask 130 and affecting the light-emitting effect of the light-emitting decorative frame 100.

[0027] In some embodiments, the light-transmitting portion 131 may be made of a light-transmitting material, such as a PC material, and the light-impermeable portion 132 may be made of a black light-impermeable material, such as an ASA (a graft copolymer of acrylic rubber and acrylonitrile and styrene) or a PC / ABS (a mixture of PC and ABS (acrylonitrile-butadiene-styrene copolymer)) material. The light-transmitting mask 130 may be integrally formed by a double-material injection molding process. During the double-material injection molding, the material of the first shot is a light-transmitting material to form the light-transmitting portion 131, and the material of the second shot is a light-impermeable material to form the light-impermeable portion 132, and the light-transmitting portion 131 and the light-impermeable portion 132 are connected to each other.

[0028] In some other embodiments, the light-transmitting portion 131 and the light-impermeable portion 132 can be integrally formed of the same light-transmitting material, and the outer side of the light-impermeable portion 132 can be formed into a light-impermeable pattern by spraying black paint or laser engraving, so that the light-impermeable portion 132 can achieve a light-impermeable function.

[0029] like Figure 4 As shown, each light-emitting component 140 may include an LED lamp 141 and a PCB (printed circuit board) 142 . The PCB 142 is fixed on the bracket 110 and forms a first installation space 150 with the bracket 110 . The LED lamp 141 is fixed on the PCB 142 and is located in the first installation space 150 .

[0030] A second installation space 160 is formed between the light-transmitting mask 130 and the bracket 110. The second installation space 160 is independent of the first installation space 150. The light guide sheet 120 is located in the second installation space 160. The root of the light guide sheet 120 can pass through the bracket 110 and extend into the first installation space 150. The LED lamp 141 is aligned with the root of the light guide sheet 120. In this way, the LED lamp can be driven to emit light through the PCB 142. The light emitted by the LED lamp irradiates the light guide sheet 120, and the linear light is converted into surface light by the light guide sheet 120 and then emitted from the top surface, and then passes through the light-transmitting mask 130 to form a matrix-type lighting effect. The bracket 110 can be provided with a through hole, which can match the root of the light guide sheet 120, and is arranged so that the root of the light guide sheet 120 can be fixed on the bracket 110 after being inserted into the through hole, and each fixed light guide sheet 120 is parallel to each other. In this way, during installation, it is only necessary to insert each light guide sheet 120 into the through hole to achieve fixation, which is very convenient.

[0031] In some embodiments, a plurality of light shading plates 170 corresponding to each light guide plate 120 may be provided in the first installation space 150. Each light shading plate 170 is bonded and fixed to the bracket 110 and surrounds the corresponding light guide plate 120, thereby separating the light guide plate 120 from other light guide plates 120. This can effectively separate the light emitted by different light guide plates 120 to avoid mutual influence, and can make the boundaries between the light emitted by adjacent light guide plates 120 clear.

[0032] In some embodiments, the light emitting component 140 may also be a COB light source, a flexible PCB component, or other forms of light emitting components.

[0033] In an exemplary embodiment, the distance between any two light guide plates 120 is about 5 mm, and a total of 170 light guide plates 120 are disposed on the bracket 110 .

[0034] like Figure 4 As shown, in some embodiments, the bracket 110 can be snap-fitted to the front bumper 200 and the grille 300 respectively, so that the bracket 110 is installed on the front bumper 200 .

[0035] The luminous decorative frame 100 and the front bumper of the embodiment of the present invention convert the line light source into a surface light source through a plurality of light guide plates 120 evenly arranged along the circumference of the bracket 110, and form a matrix light-emitting effect after passing through the transparent mask 130, thereby achieving a visually refreshing appearance effect.

[0036] The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. The above embodiment of the present invention can also be modified in various ways. That is, all simple, equivalent changes and modifications made according to the claims and the description of the present invention fall within the scope of protection of the claims of the present invention. The contents not described in detail in the present invention are all conventional technical contents.
