Description

Technical Field

[0001] This utility model relates to the field of automotive ambient lighting technology, specifically to an ambient light for an air conditioning vent. Background Technology

[0002] As automotive functions become more diverse, lighting configurations are becoming increasingly complex, especially interior lighting. Due to limited interior space, the integration requirements for interior lighting are becoming higher and higher. For ambient lighting around air vents, in addition to ensuring luminous efficacy, it is not only required to have a high degree of integration and be compatible with the structure of the air vents, but also to avoid deformation due to thermal expansion and contraction, given the large temperature difference at the air vents.

[0003] Referring to Chinese Patent 202411134192.5, this patent uses a lamp head to emit light, which is then guided to the outer blades via a light strip, causing the outer blades to emit light and achieving an ambient lighting effect at the air outlet. This patent has the following problems: 1. Using a lamp head for illumination and a light strip for guiding light results in a large space occupation, low integration, and difficulty in layout; 2. The outer blades emit light as a whole, resulting in a large luminous area, uneven light emission, and poor luminous efficiency; 3. Due to the large temperature difference at the air outlet, the outer blades are prone to deformation, leading to poor durability. Utility Model Content

[0004] To address the technical problems of low integration, poor luminous efficiency, and poor durability, this utility model provides an ambient light for an air conditioning vent.

[0005] The technical solution is as follows:

[0006] This application relates to an air conditioning vent ambient light, including an vent housing with an air supply channel and a light-emitting module mounted on the vent housing. At least one air guide blade is rotatably mounted in the air supply channel. Each air guide blade includes a light guide plate with a sheet-like structure and two side cover plates disposed on both sides of the thickness direction of the light guide plate. The outer edge of each light guide plate near the outlet of the air supply channel is exposed between the two adjacent side cover plates to form a light-emitting strip. Both ends of each light guide plate in the length direction are rotatably mounted on the circumferential sidewall of the air supply channel through an integrally formed rotating shaft. The light-emitting module can simultaneously send light to the light-inlet end face of at least one rotating shaft of each light guide plate.

[0007] The above-mentioned air conditioning vent ambient light uses side covers on both sides of the light guide plate, which effectively prevents deformation of the light guide plate due to large temperature differences and improves the durability of the light guide plate. At the same time, only one outer edge of the light guide plate forms a light-emitting surface, resulting in concentrated light emission, more uniform light emission, higher brightness, and better light efficiency. The two ends of the light guide plate are equipped with pivots, which take into account both the light intake and the rotation of the air guide blades. The structure is simple and reliable, and it is consistent with the style of the air vent, making it more aesthetically pleasing. The light-emitting module is installed on the air vent housing, which has a high degree of integration, occupies little space, and is easy to arrange.

[0008] In some embodiments, the light-emitting strip may protrude outward from the outer edges of the corresponding two side cover plates, be flush with the outer edges of the corresponding two side cover plates, or be recessed inward between the corresponding two side cover plates.

[0009] In some embodiments, the air supply duct is equipped with at least three parallel guide vanes.

[0010] In some implementations, each light guide plate is integrally formed with the side cover plates on both sides using a two-color injection molding process.

[0011] In some embodiments, the surface of the light-emitting strip is coated with a decorative coating, and the decorative coating is treated with a laser engraving process to make it translucent.

[0012] In some embodiments, the light-emitting module is a PCBA that integrates a number of LED beads, and at least one end of each air guide blade is provided with the PCBA, and the light-emitting surface of the LED beads on each PCBA is respectively facing the light-inlet end face of the corresponding rotating shaft.

[0013] In some embodiments, the air outlet housing is provided with a module bracket for mounting a PCBA. The module bracket is provided with a first slot and a buckle. The PCBA is provided with a second slot adapted to the first slot and a buckle hole adapted to the buckle. The PCBA can be embedded in the first slot through the second slot and engaged with the buckle through the buckle hole.

[0014] In some embodiments, the air outlet housing and the module bracket are integrally formed.

[0015] In some embodiments, the air outlet housing is a trumpet-shaped structure that gradually widens from the inside out. Attached Figure Description

[0021] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0022] like Figure 1 As shown, an air conditioner vent ambient light mainly includes an vent housing 1, air guide vanes 2, and a light-emitting module 3.

[0023] like Figures 1 to 3 As shown, the air outlet housing 1 is an annular structure with an air supply channel 11 in the middle. The air supply channel 11 gradually increases in size from the inside to the outside, which is conducive to the diffusion of air conditioning air. Several mounting holes 13 for mounting air guide vanes 2 are respectively opened on the opposite side walls of the air supply channel 11. A module bracket 12 for mounting the light-emitting module 3 is provided on the outer wall of the air outlet housing 1 near the mounting holes 13. The number of module brackets 12 is determined according to the light-gathering method of the light guide plate 21. In this embodiment, the light guide plate 21 adopts a one-end light-gathering method, and the number of module brackets 12 is one. The module bracket 12 extends from the root away from the outer wall of the air outlet housing 1 and then bends outward. Its cross-section is "L" shaped. Two first slots 121 are provided on the module bracket 12, and a buckle 122 is provided between the two first slots 121. The air outlet housing 1 and the module bracket 12 are integrally formed, with a stable and reliable structure and low production cost.

[0024] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the air guide blade 2 includes a light guide plate 21 with a sheet-like structure and two side cover plates 22 disposed on both sides of the light guide plate 21 in the thickness direction. The outer edge of each light guide plate 21 near the outlet of the air supply channel 11 is exposed between the two adjacent side cover plates 22 to form a light-emitting strip 212. Due to the blocking effect of the two side cover plates 22, the light from the light guide plate 21 is concentrated on the light-emitting strip 212, resulting in uniform light emission and good light efficiency. Depending on the actual requirements for light efficiency, the light-emitting strip 212 may protrude outward from the outer edge of the corresponding two side cover plates 22, be flush with the outer edge of the corresponding two side cover plates 22, or be recessed inward between the corresponding two side cover plates 22. In this embodiment, the light-emitting strip 212 protrudes outward from the outer edge of the corresponding two side cover plates 22, which is more effective in displaying the flowing effect of ambient lighting. The light guide plate 21 and the side cover plates 22 on both sides can be separate structures and connected by plugging, pasting or other methods, or they can be integrally molded. In this embodiment, each light guide plate 21 and the side cover plates 22 on both sides are preferably integrally molded by a two-color injection molding process, which has high structural strength and good durability.

[0025] The surface of the light-emitting strip 212 is coated with a decorative coating, which is then laser-engraved to allow light to pass through. The light guide plate 21 has low production cost, high durability, and a consistent style with the air outlet housing 1, resulting in a better texture. Each light guide plate 21 has an integrally formed rotating shaft 211 at both ends along its length. The rotating shafts 211 extend beyond the edge of the side cover plate 22 and are located in the middle of the side cover plate 22, making the rotation of the light guide plate 21 more stable and reliable. Each light guide plate 21 is rotatably mounted on the corresponding mounting hole 13 via the rotating shafts 211 at both ends. The end faces of the two rotating shafts 211 are the light-inlet end faces of the light guide plate 21. Depending on actual needs, the light guide plate 21 can adopt a one-end light-inlet or two-end light-inlet configuration. In this embodiment, each light guide plate 21 uses a single-end light-inlet configuration. Three parallel air guide blades 2 are installed in the air supply channel 11, enabling ambient lighting effects such as breathing, flowing light, and color-controlled ambient lighting.

[0026] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the light-emitting module 3 is a PCBA32 integrating several LED beads 31. The PCBA32 is located at the light-inlet end of each air guide blade 2, and the light-emitting surface of the LED beads 31 on each PCBA32 is respectively facing the light-inlet end surface of the corresponding rotating shaft 211. The PCBA32 is provided with a second slot 321 corresponding to the first slot 121 and a locking hole 322 adapted to the buckle 122. The PCBA32 can be embedded in the first slot 121 through the second slot 321 and engaged with the buckle 122 through the locking hole 322. The installation method is simple and reliable. The PCBA32 is connected to the connector 4 through the wire harness 5, which is convenient for layout and flexible in use.
