[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Please refer to Figures 1 to 4 An embodiment of the utility model provides an atmosphere lamp, which includes: an integrally formed atmosphere lamp bracket 1 and a light guide 2 accommodated in the atmosphere lamp bracket 1, the atmosphere lamp bracket 1 is formed with a receiving groove 11 for accommodating the light guide 2, and a mask portion 14 is formed on one side of the notch of the receiving groove 11; by integrally forming the mask portion 14 on the atmosphere lamp bracket 1, the assembly tolerance between the atmosphere lamp bracket 1 and the mask portion 14 is reduced, thereby improving the structural matching accuracy between the atmosphere lamp bracket 1 and the mask portion 14.

[0026] Furthermore, the light guiding direction of the light guide 2 is toward the light emitting area of ​​the mask part 14, so that the light guide 2 is accommodated in the atmosphere lamp bracket 1, and the light guide 2 can conduct light to the mask part 14. Based on the one-piece molded atmosphere lamp bracket 1 structure, the assembly error between the light guide 2 and the mask part 14 is reduced, and the light transmission effect of the light guide 2 on the mask part 14 of the atmosphere lamp bracket 1 is improved.

[0027] Specifically, the light guide 2 is completely accommodated in the accommodating groove 11 of the atmosphere lamp bracket 1, and one side surface of the light guide 2 is flush with the notch of the accommodating groove 11 between the atmosphere lamps, so that the light guide 2 can be embedded in the atmosphere lamp bracket 1 and improve the stability of the cooperation between the light guide 2 and the atmosphere lamp bracket 1.

[0028] Specifically, a plurality of limiting protrusions are arranged in the receiving groove 11 of the atmosphere lamp bracket 1. The plurality of limiting protrusions limit the assembly position of the light guide 2 in the receiving groove 11 of the atmosphere lamp bracket 1, thereby fixing the position of the light guide 2 and ensuring the accuracy of the matching position of the light guide 2 and the atmosphere lamp bracket 1.

[0029] Several limiting protrusions are arranged at the notch position of the receiving groove 11, so that when the light guide 2 is embedded in the receiving groove 11 of the atmosphere light bracket 1, the position of the light guide 2 can be limited based on the several limiting protrusions, so that the light guide 2 can be covered in the receiving groove 11.

[0030] Furthermore, one side of the light guide 2 is in contact with the limiting block, thereby improving the tightness of the assembly between the light guide 2 and the receiving groove 11 and preventing the light guide 2 from being separated from the atmosphere lamp bracket 1 .

[0031] Specifically, the atmosphere lamp bracket 1 is provided with a plurality of heat dissipation openings, and the plurality of heat dissipation openings are distributed one by one below a plurality of limiting protrusions. The assembly working state of the light guide 2 is dissipated based on the heat dissipation openings to avoid the accumulation of working heat of the light guide 2 and the thermal expansion and deformation of the atmosphere lamp bracket 1 when the atmosphere lamp works for a long time.

[0032] Furthermore, the heat dissipation opening can improve the structural flexibility of the atmosphere lamp bracket 1 , so that the atmosphere lamp bracket 1 has a certain amount of deformation and mobility, so that the light guide 2 can be assembled in the receiving groove 11 of the atmosphere lamp bracket 1 .

[0033] Specifically, one side of the atmosphere light bracket 1 is configured as the mask part 14, and the other side of the atmosphere light bracket 1 is provided with a plurality of mounting parts 12. The atmosphere light bracket 1 is installed on the position of the car door frame based on the plurality of mounting parts 12. The plurality of mounting parts 12 are evenly arranged along the length direction of the atmosphere light bracket 1, and the mounting parts 12 are provided with mounting holes 121, so that the atmosphere light bracket 1 can fit on the contour of the car door frame. The mounting part 12 of the atmosphere light bracket 1 is fixed to the car door frame with bolts, thereby realizing the installation and fixation of the atmosphere light bracket 1 and the car door frame.

[0034] Specifically, an installation groove 13 is provided at one end of the atmosphere lamp bracket 1, and a driver 21 is configured at one end of the light guide 2. The driver 21 is accommodated in the installation groove 13. The driver 21 is used to control the light color and light intensity of the light guide 2. LED lamp beads are provided in the driver 21, and the light emitting direction of the LED lamp beads is toward the light guide 2, so that the driver 21 can achieve the use effect of the atmosphere lamp based on the LED lamp beads in conjunction with the light guide 2.

[0035] Furthermore, the atmosphere light driver 21 extends an electrical connection line 211 outward, and the electrical connection between the atmosphere light driver 21 and the external working circuit is realized based on the electrical connection line 211, so that the driver 21 can control the atmosphere light to present different lighting effects based on the car's vehicle system.

[0036] Specifically, the material of the atmosphere lamp bracket 1 can be PCABS alloy material, which is a special alloy made by blending polycarbonate (PC) and acrylonitrile-butadiene-styrene copolymer (ABS). It combines the advantages of polycarbonate (PC) and acrylonitrile-butadiene-styrene (ABS) and has high strength, good toughness and weather resistance.

[0037] The material of the atmosphere lamp bracket 1 can also be ASA material. The ASA material is a copolymer composed of acrylonitrile, styrene and acrylate, has excellent weather resistance and chemical corrosion resistance, can maintain stable performance for a long time in outdoor environments, and is suitable for the manufacture of the atmosphere lamp bracket 1.

[0038] Specifically, the material of the light guide 2 can be PMMA (polymethyl methacrylate), PC (polycarbonate), glass optical fiber and one of high molecular polymers. PC (polycarbonate) is also a highly transparent plastic with high strength, high toughness and good heat resistance. PMMA (polymethyl methacrylate) is a highly transparent plastic with excellent light-guiding performance and weather resistance. It is one of the ideal materials for manufacturing the atmosphere light guide 2, and the cost of PMMA (polymethyl methacrylate) material is low. Based on the PMMA (polymethyl methacrylate) material, the overall production cost of the atmosphere lamp can be reduced.

[0039] Specifically, a mating groove is provided on one side of the light guide 2. When the light guide 2 is embedded in the accommodating groove 11 of the atmosphere lamp bracket 1, the light guide 2 and the atmosphere lamp bracket 1 can be matched to form an integral structure, so that the mating groove of the light guide 2 can be matched with the car door frame, thereby improving the mating reliability of the atmosphere lamp and the car door frame, and improving the assembly appearance of the atmosphere lamp.

[0040] The present invention provides an ambient light, wherein the ambient light is provided with an ambient light bracket 1 having an integrally formed structure and a mask portion 14, so that a light guide 2 can be accommodated within a receiving groove 11 of the ambient light bracket 1. This reduces the assembly tolerance between the ambient light bracket 1 and the mask portion 14, improves the accuracy of the ambient light's light output, and thus enhances the ambient light's light output effect. Because the ambient light's light guide 2 is completely accommodated within the receiving groove 11 of the ambient light bracket 1, light from the ambient light's light guide 2 can accurately access the light-emitting surface of the mask portion 14, resulting in an excellent ambient light output effect.
