[0026] Currently, some car models use a light guide or light guide strip embedded in the toggle switch body to create ambient lighting for the air vents. The ambient light source is placed on one side of the air vent housing, and the light emitted by the light source is transmitted to the surface of the toggle switch body through the light guide to achieve the lighting effect.

[0027] The above solution improves integration to some extent, but it requires additional space in the housing around the air vents, squeezing the already tight space inside the center console or dashboard. This negatively impacts the layout of other key components such as wiring harnesses, air ducts, and airbags, increasing the complexity of the overall vehicle layout.

[0028] In view of this, the present invention provides an automotive air conditioning vent assembly and vehicle. By directly setting the light-emitting structure below the light guide structure, the ambient lighting function is integrated in the vertical direction of the air vent. This eliminates the need for additional installation space occupied by the side housing of the air vent in the traditional solution, improves the utilization rate of the space inside the center console or dashboard, and provides more space for the layout of other key components such as air ducts, wiring harnesses, and airbags.

[0029] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0030] like Figure 1 and Figure 2 As shown in the figure, this utility model embodiment proposes an automotive air conditioning vent assembly, which includes: An air vent frame 100 is provided, which includes an air cavity 810 and an air outlet 820 communicating with the air cavity 810. It can be understood that the air cavity 810 is connected to the air duct of the car's air conditioning system. Cold or hot air enters the air cavity 810 through the air duct and is blown out through the air outlet 820, thereby achieving cooling or heating of the vehicle interior. Specifically, the air vent frame 100 can be installed on the dashboard, and the air vent frame 100 can be square. The air outlet blades 200 are rotatably mounted on the air outlet 820. It can be understood that by rotating the air outlet blades 200, the direction of cold or hot air blowing from the air outlet 820 can be adjusted to meet the needs of different users. Specifically, rotating shafts can be provided at both ends of the air outlet blades 200, and these shafts are rotatably connected to the air outlet frame 100. The actuating structure 300 is drivenly connected to the air outlet blade 200. It can be understood that the actuating structure 300 can swing or slide, thereby driving the air outlet blade 200 to rotate, thus changing the angle of the air outlet blade 200 and adjusting the air outlet direction. The specific structure of the actuating structure 300 and the air outlet blade 200 can refer to commonly used designs in existing vehicles, and is not limited here. A light guide structure 400 is slidably disposed at the air outlet 820 and connected to the actuating structure 300 to move synchronously with it. Specifically, the light guide structure 400 can be disposed on the front of the actuating structure 300, i.e., the surface facing away from the air outlet 810, or on the side of the actuating structure 300, or it can cover the end of the actuating structure 300 away from the air outlet blade 200; no limitation is made here. By providing the light guide structure 400 connected to the actuating structure 300, light can be transmitted to the actuating structure 300, achieving the luminous effect of the actuating structure 300; and A light-emitting structure 500 is disposed at the air outlet 820 and below the light guide structure 400, and is used to provide light to the light guide structure 400. It is understood that by distributing the light-emitting structure 500 at the air outlet 820 and below the light guide structure 400, the light emitted by the light-emitting structure 500 can be directly transmitted to the toggle structure 300 through the light guide structure 400. This shortens the light propagation path, reduces light efficiency attenuation, and improves brightness uniformity. Optionally, the light-emitting structure 500 can be disposed at the bottom of the air outlet 820 to reduce its impact on the airflow from the air outlet 820.

[0031] In the technical solution adopted in this embodiment, by directly setting the light-emitting structure 500 below the light guide structure 400, it can be understood that the light-emitting structure 500 is set in the air outlet 820 and located below the toggle structure 300. The light emitted by the light-emitting structure 500 is transmitted to the toggle structure 300 through the light guide structure 400. When the movement of the toggle structure 300 drives the air outlet blade 200 to rotate, the light guide structure 400 can follow the movement of the toggle structure 300, realizing the light-emitting effect of the toggle structure 300. It also realizes the integration of the ambient light function in the vertical direction of the air outlet 820, eliminating the need for additional installation space occupied by the side housing of the air outlet 820 in the traditional solution, improving the space utilization rate inside the center console or dashboard, and providing more layout space for other key components such as air ducts, wiring harnesses, and airbags.

[0032] In one embodiment of this utility model, reference is made to Figure 2 and Figure 3 The light guide structure 400 includes: The outer casing 410 is fixedly connected to the actuating structure 300, and a light-transmitting portion is provided on the side of the outer casing 410 away from the air cavity 810; and A light guide 420 is provided, with one end located inside the housing 410 and corresponding to the light-transmitting portion, and the other end extending to the bottom of the housing 410. The light-emitting structure 500 emits light towards the light guide 420.

[0033] Specifically, the light guide structure 400 includes a housing 410 and a light guide element 420. The housing 410 can be mounted on the end of the toggle structure 300 away from the air outlet blade 200 and can move together with the toggle structure 300. The side of the housing 410 away from the air cavity 810 has a light-transmitting portion, which can emit light to achieve a light-emitting effect. Since the housing 410 is mounted on the toggle structure 300, the light-emitting effect of the toggle structure 300 can be achieved. Moreover, by directly mounting the housing 410 on the end of the toggle structure 300, no major modifications to the toggle structure 300 are required. The light guide element 420 is connected to the housing 410, with one end of the light guide element 420 facing the light-transmitting portion and the other end facing the light-emitting structure 500, allowing light from the light-emitting structure 500 to be transmitted to the light-transmitting portion via the light guide element 420 to achieve a light-emitting effect. Optionally, the material of the light-transmitting portion is a light-transmitting material, such as glass or polycarbonate, and is not limited here. Specifically, the light emission angle of the light-emitting structure 500 is greater than that formed by the movement of the light-blocking component. This ensures that the light-blocking component can receive the light emitted by the light-emitting structure 500 during the movement process, thus ensuring the light emission of the light-transmitting part and achieving the light emission effect of the toggle structure 300.

[0034] In one embodiment of this utility model, reference is made to Figure 1 and Figure 3 The automotive air conditioning vent assembly also includes a grille strip 600, which is disposed at the air outlet 820; The outer casing 410 is provided with a clamping opening 411, which clamps the grille bar 600 and is slidably connected to the grille bar 600.

[0035] Specifically, the outer casing 410 is provided with a clamping port 411, which clamps onto the grille strip 600. The grille strip 600 supports the outer casing 410, reducing the stress on the toggle structure 300. Furthermore, the clamping method facilitates the assembly and disassembly of the outer casing 410, reducing maintenance costs and eliminating the need for complex fixing structures, resulting in a simpler structure. Additionally, the grille strip 600 extends along the sliding direction of the light guide structure 400, and the clamping port 411 slides along the grille strip 600, ensuring the normal movement of the toggle structure 300. Optionally, multiple grille strips 600 can be provided along the vertical direction of the air outlet 820, and the clamping port 411 can clamp onto any one of the grille strips 600. Further, the grille strip 600 can be clamped onto a grille strip 600 near the ground.

[0036] In one embodiment of this utility model, reference is made to Figure 3The light guide 420 includes a first light guide 421, a second light guide 422, and a third light guide 423. The first light guide 421 is located between the light-transmitting part and the grille strip 600. The second light guide 422 is bent and connected to the first light guide 421 and is located below the grille strip 600. The third light guide 423 is bent and connected to the second light guide 422 and extends to the bottom of the housing 410. The light emission direction of the light-emitting structure 500 is towards the third light guide 423.

[0037] Specifically, the first light guide 421 faces the light-transmitting part, the third light guide 423 faces the light-emitting structure 500, and the second light guide 422 connects the first light guide 421 and the second light guide 422, thereby transmitting the light from the light-emitting structure 500 to the light-transmitting part to achieve the light-emitting effect. The second light guide 422 is bent to connect the first light guide 421 and the third light guide 423, which can avoid the grille strip 600 and facilitate the clamping port 411 to clamp the grille strip 600.

[0038] In one embodiment of this utility model, reference is made to Figure 2 The outer casing 410 includes at least a first side plate 412, a second side plate 413, and a third side plate 414. The first side plate 412 and the second side plate 413 are vertically spaced to form the clamping opening 411. The third side plate 414 connects the first side plate 412 and the second side plate 413. The third side plate 414 is made of transparent material and forms the light-transmitting portion. Specifically, the first side plate 412 and the second side plate 413 form the clamping opening 411 vertically spaced for securely mounting the outer casing 410. The third side plate 414 connects the first side plate 412 and the second side plate 413 and is made of transparent material. As a light-transmitting portion, it allows the light emitted by the light-emitting structure 500 to be directly and evenly presented on the surface of the outer casing 410 or the actuating structure 300 through this light-transmitting portion, achieving a better light-emitting effect. Since the light-transmitting part is formed by the third side panel 414 itself, there is no need to install separate light-transmitting parts during the assembly process. This reduces the number of parts and assembly steps, lowers direct labor costs, effectively avoids quality fluctuations caused by the cumulative tolerances of multiple parts, and improves product yield and consistency. Moreover, the third side panel 414 is entirely light-transmitting, forming a seamless and complete light-emitting surface. Compared with the traditional solution of embedding small light guide strips, the solution of this application can provide a large area of ​​uniform brightness, enhancing the overall integrity, modernity, and premium feel of the product, and improving the visual grade of the interior.

[0039] In one embodiment of this utility model, reference is made to Figures 1 to 3The automotive air conditioning vent assembly also includes a light source support 700, which is located at the air outlet 820 and fixedly connected to the air outlet frame 100. The light-emitting structure 500 is elongated and positioned on the light source support 700, which is located below the housing 410. Thus, the light source support 700 provides support for the light-emitting structure 500, facilitating its installation. Furthermore, the elongated shape of the light-emitting structure 500 increases its light-emitting range, ensuring that the movement of the light-transmitting component remains within the light-emitting range of the structure 500, guaranteeing that the light-transmitting component receives light from the structure 500 throughout its movement.

[0040] In one embodiment of this utility model, the light-emitting structure 500 is embedded in the surface of the light source support 700 facing the light guide structure 400. This reduces the combined thickness of the light source support 700 and the light-emitting structure 500, further minimizing the adverse effects on the airflow from the air outlet 820.

[0041] In one embodiment of this utility model, reference is made to Figure 2 The light source support 700 is provided with a groove 710, the light-emitting structure 500 is disposed in the groove 710, and the light guide 420 is slidably connected to the groove 710. The groove 710 allows the light-emitting structure 500 to be easily embedded in the light source support 700. Furthermore, the groove 710 can guide the sliding of the light guide structure 400, preventing displacement. In other embodiments, the light-emitting structure 500 is provided with a guide groove, and the light guide structure 400 is slidably disposed in the guide groove.

[0042] In one embodiment of this utility model, reference is made to Figure 2 and Figure 3The air outlet frame 100 includes a first frame portion 110 and a second frame portion 120. One end of the second frame portion 120 extends into the interior of the first frame portion 110. The air cavity 810 is disposed in the first frame portion 110, and the air outlet blade 200, the light guide structure 400, and the air outlet 820 are disposed in the second frame portion 120. Thus, the nested first frame portion 110 and the second frame portion 120 achieve a partitioned layout of functional modules, improving the integration of the air conditioning outlet 820. Specifically, the air cavity 810 is disposed within the first frame portion 110 to ensure stable airflow regulation; while the air outlet blade 200, the light guide structure 400, and the air outlet 820 are integrated into the second frame portion 120, and one end of the second frame portion 120 extends and embeds into the interior of the first frame portion 110, enhancing the overall structural compactness. In one embodiment, the second frame portion 120 and the first frame portion 110 are detachably configured. Thus, the second frame portion 120 can serve as an independent decorative frame, allowing for flexible changes based on vehicle model configuration or user preferences without altering the underlying first frame portion 110, achieving personalized compatibility. Of course, in other embodiments, the first frame portion 110 and the second frame portion 120 can also be integrally injection molded; this is not a limitation.

[0043] In one embodiment of this utility model, the light-emitting structure 500 is configured as an ambient light, thus integrating functional operation guidance with emotional ambient lighting. When the user adjusts the airflow, the interaction between their hand movements and the light-emitting toggle structure 300 enhances the sense of ritual and technology in the operation, achieving a unity between human-computer interaction and the creation of the in-vehicle environment. And / or, the light-emitting structure 500 includes a light-emitting element and a circuit board electrically connected to the light-emitting element. The circuit board is provided with an electrical connector for connecting to an external power source. This allows for convenient wiring via the electrical connector. Furthermore, the circuit board can control the light-emitting effect of the light-emitting element. Optionally, the light-emitting element is elongated, with a circuit board at its longitudinal end. Specifically, the light-emitting element has a guide groove.
