[0037] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0038] Reference below Figure 1-Figure 16 The air outlet structure according to the embodiment of the utility model is described.

[0039] like Figure 1 As shown, the air outlet structure includes: a light source component 3 and a light guide fan blade 1.

[0040] The light guide blade 1 is rotatably disposed at the air outlet 41 , the light source 3 faces one end surface of the light guide blade 1 , and a reflective tooth 5 is disposed on a side surface of the light guide blade 1 facing away from the air outlet 41 .

[0041] The two ends of the light guide blade 1 along its length direction are rotatably connected to the air outlet housing 4. A light source 3 is disposed at one end of the light guide blade 1 along its length direction so that the light source 3 faces one end surface of the light guide blade 1.

[0042] See Fig.16 As shown, the surface of the light guide blade 1 facing away from the air outlet 41 is the back side 12 of the light guide blade 1 , and reflective teeth 5 are provided on the back side 12 so that the bottoms of the reflective teeth 5 are on the same reference plane.

[0043] When in use, the light emitted by the light source 3 enters the light guide blade 1 through one end surface of the light guide blade 1, and the incident light is totally reflected by the reflective teeth 5 of the light guide blade 1, thereby producing a crystal clear and dynamic effect.

[0044] In this way, the light guide fan blades 1 can not only realize different air outlet directions by rotating, but also emit light to realize the atmosphere light effect, and the appearance of the light-transmitting cover is omitted, so that the light guide fan blades 1 can be directly displayed as an appearance part at the air outlet 41, with a novel shape, which can enhance the design sense of the vehicle body interior.

[0045] Thus, the fan blade function and the atmosphere light function are integrated on the light guide blade 1. The light guide blade 1 can not only rotate to achieve different air outlet directions, but also achieve the atmosphere light effect, and the light-transmitting cover structure is omitted, so that the light guide blade 1 is displayed at the air outlet 41 as an appearance part, with a novel shape, which can enhance the design sense of the vehicle body interior. In addition, the atmosphere light and the light-transmitting cover are omitted, the structure is simple, and the installation is convenient.

[0046] Furthermore, in the direction from one end to the other end of the light guide blade 1 , the reduction rate of the light reflecting teeth 5 varies.

[0047] Since the light of the light source 3 is emitted from one end face of the light guide blade 1, the luminous intensity at different positions of the light guide blade 1 is different. In order to ensure that the light emitted by the light guide blade 1 is uniform, by adjusting the reduction rate of the reflective teeth 5 at different positions of the light guide blade 1, the brightness of the original high luminous intensity area can be reduced, and the brightness of the original low luminous intensity area can be increased, so that the light guide blade 1 emits uniform light.

[0048] Among them, one side surface of the reflective tooth 5 is the reflective surface 6, that is, when the incident light is emitted to the reflective surface 6 of the reflective tooth 5, the light will be reflected back into the light-guiding fan blade 1 and emitted to the outside to achieve a smart lighting effect.

[0049] like Figure 3 As shown, the design of the reflective teeth 5 utilizes the principle of total reflection, that is, for light, when the incident angle is greater than a certain value, the interface between the two media will reflect all the incident light back to the original medium. This phenomenon is called "total reflection".

[0050] For the present application, when the incident angle is greater than the total reflection angle, the light will be completely reflected from the reflective surface 6 of the reflective tooth 5 back into the light-guiding fan blade 1 and emitted to the outside.

[0051] Furthermore, the reduction rate of the reflective teeth 5 is directly proportional to the luminous intensity of different areas of the light-guiding blade 1 .

[0052] In other words, the light guide blade 1 has a high reduction rate of the reflective teeth 5 in the area of ​​high luminous intensity, and a low reduction rate of the reflective teeth 5 in the area of ​​low luminous intensity. In this way, for the area with higher luminous intensity, the reduction rate of the reflective teeth 5 is increased, so that less light can be emitted, thereby reducing the brightness of the area; for the area with lower luminous intensity, the reduction rate of the reflective teeth 5 is reduced, so that more light can be emitted, thereby enhancing the brightness of the area. Therefore, by adjusting the reduction rate of the reflective teeth 5, the areas with different luminous intensities can be made as uniform as possible, so that the light output of the light guide blade 1 is more uniform.

[0053] Furthermore, a groove 11 is provided on the surface of the light guide blade 1 facing away from the air outlet 41 , and a reflective tooth 5 is provided in the groove 11 . The depth of the reflective tooth 5 in the groove 11 is inversely proportional to the reduction rate of the reflective tooth 5 .

[0054] refer to Figure 4 and Figure 5 As shown, a groove 11 is provided on the inner side of the light guide blade 1, and a reflective tooth 5 is arranged in the groove 11. Figure 4 As shown, the depth of the reflective teeth 5 is small, the reflective surface 6 is small, and correspondingly, the reduction rate is high, and the brightness will be low; see Figure 5 As shown, the depth of the reflective tooth 5 is large, the reflective surface 6 is large, the corresponding light is low, the attenuation rate is low, and the brightness is high.

[0055] The bottoms of the reflective teeth 5 are all on the same reference of the groove 11, so as to adjust the depth of the reflective teeth 5. That is, the depth of the two sides where the reflective teeth 5 are connected to the back surface 12 of the light guide blade 1 is adjusted.

[0056] Therefore, by adjusting the depth of the reflective teeth 5 to change the magnitude of the attenuation rate, the regions with different luminous intensities can be made as uniform as possible, thereby achieving a more uniform light output effect of the light guide blades 1 .

[0057] Furthermore, along the direction of the light guide blade 1 from one end close to the light source 3 to one end far away from the light source 3 , the arrangement pitch of the reflective teeth 5 gradually decreases.

[0058] Since the farther from the light source, the more light is lost, the number of reflective teeth 5 is increased by increasing the compactness of the arrangement of the reflective teeth 5. Specifically, the farther the reflective teeth 5 on the light guide blade 1 are from the light source component 3, the more compact the arrangement is, and the more light emitted by the light source component 3 is reflected by the reflective teeth 5; the closer the reflective teeth 5 are to the light source component 3, the less compact the arrangement is, and the less light emitted by the light source component 3 is reflected by the reflective teeth 5.

[0059] Therefore, by increasing the number of reflective teeth 5 , the number of reflective surfaces 6 is increased, thereby increasing the amount of reflection, thereby ensuring that the emitted light at various locations of the light-guiding fan blade 1 is more uniform.

[0060] In the embodiment of the present invention, the light source 3 may be a three-color light source, so that the light source 3 has the characteristic of variable color. Alternatively, the light source 3 may be set with color characteristics according to actual needs to increase the use occasions of the interior atmosphere light.

[0061] like Figure 1 and Figure 2 As shown, the air outlet structure further includes: a light mixing component 2 , a light emitting end of the light mixing component 2 faces an end surface of the light guiding fan blade 1 , and a light input end of the light mixing component 2 is connected to the light source component 3 .

[0062] See Figure 6 The schematic diagram of light transmission by the light-mixing component 2 shown in the figure, the light-mixing component 2 plays the role of conducting and mixing light. The light emitted by the light source component 3 enters the light-mixing component 2, and the multi-color light is evenly mixed in the light-mixing component 2, and then enters the light-guiding fan blade 1, shines on the reflective teeth 5, and is all emitted through total reflection.

[0063] The light mixing element 2 is made of PMMA and can achieve a uniform light mixing effect after multiple reflections of the light emitted by the light source element 3 .

[0064] Furthermore, the light mixing element 2 is a bent tube structure, and the cross-sectional center of the light inlet end of the light mixing element 2 is arranged opposite to the light emitting center of the light source element 3 .

[0065] In this way, the light mixer 2 is set to be curved, which increases the optical path, and can achieve uniform mixing of light through multiple reflections in the shorter distance light mixer 2, so that the light entering the light guide blade 1 from the light mixer 2 is uniform mixed light that can be directly projected. In addition, the curved light mixer 2 is conducive to spatial arrangement.

[0066] Exemplarily, the light mixing element 2 is a cylindrical curved tube structure, and of course, it may also be a special-shaped curved tube structure.

[0067] Furthermore, the cross-sectional center of the light-incoming end of the light-mixing element 2 is arranged relative to the light-emitting center of the light source element 3 to ensure that more light emitted by the light source element 3 can pass through the light-mixing element 2 and be emitted, thereby reducing light source loss.

[0068] Furthermore, the light mixing element 2 has a light incident surface and a light emitting surface. Light enters the light mixing element 2 from the light incident surface, is reflected inside the light mixing element 2, and is emitted from the light emitting surface.

[0069] See Figure 6 As shown, the incident light enters the light mixing element 2 through the light incident surface and is reflected multiple times in the light mixing surface 3, so that the incident light is staggered and mixed in the light mixing element 2, thereby achieving the effect of mixing light.

[0070] Furthermore, the center of the light incident surface corresponds to and remains parallel to the luminous center of the light source component 3 , the light incident surface is a plane, and the distance between the light incident surface and the luminous center of the light source component 3 is L, and L satisfies the relationship: 0.6mm≤L≤1.2mm.

[0071] In this way, it is ensured that more light emitted by the light source component 3 can pass through the light mixing component 2 and be emitted, thereby reducing the light source loss rate.

[0072] Furthermore, the light mixing element 2 is composed of a plurality of light mixing surfaces.

[0073] In this way, the light mixing element 2 includes several light mixing surfaces, and the incident light will form multiple periodic total internal reflections at the side surfaces. The uneven light source distribution is folded multiple times, and the light source distribution is uniformed by superposition. The more reflections there are, the stronger the light uniformity effect is. The light mixing element 2 increases the number of light reflections to achieve mixing of multi-color light sources into uniform mixed light in a shorter distance.

[0074] The ultimate goal of light mixing is to disperse the light so that light of different wavelengths can be mixed together. When the light mixing element 2 is circular, the light is transmitted along a relatively fixed route, which results in insufficient light dispersion; and the light mixing surface has more reflective surfaces, making the light propagation path more chaotic. In the light mixing element 2 of the same length, the light travels a longer optical path under the action of its light mixing surface.

[0075] Exemplarily, the light mixing element 2 is composed of 10 or 12 light mixing surfaces.

[0076] like Figure 7-Figure 12 In the various embodiments shown, the light mixing element 2 is composed of 10 light mixing surfaces. The light mixing element 2 is composed of 10 or 12 light mixing surfaces, which can ensure the light uniformity effect without reducing the light source loss rate and ensure the light brightness.

[0077] Furthermore, the light mixing surface is selected from one or more of a flat surface, a concave surface, and a convex surface.

[0078] Among them, the convex surface and the concave surface are both curved surfaces, which can shrink the incident light after being reflected on the mixing surface, thereby increasing the brightness.

[0079] like Figure 7 and Figure 8 In the first embodiment shown, the multiple light mixing surfaces of the light mixing element 2 are concave, so that the outer contour line of the cross section of the light mixing element 2 presents an inward concave pattern.

[0080] like Fig. 9 and Fig.10 In the second embodiment shown, the multiple light mixing surfaces of the light mixing element 2 are convex, so that the outer contour line of the cross section of the light mixing element 2 presents a protruding pattern.

[0081] like Fig.11 and Fig.12 In the third embodiment shown, the multiple light mixing surfaces of the light mixing element 2 are plane, so that the outer contour line of the cross section of the light mixing element 2 presents a diamond-like pattern, and Figure 6 The diagram shown is a schematic diagram of light propagation of the light mixing element 2 of the third embodiment.

[0082] like Fig.13 In the fourth embodiment shown, the light mixing surface of the light mixing element 2 is a convex surface, so that the light mixing element 2 forms a circular tube structure.

[0083] like Fig.14 In the fifth embodiment shown, the multiple light mixing surfaces of the light mixing element 2 are composed of flat surfaces and convex surfaces, so that the light mixing element 2 forms a fan-shaped structure.

[0084] like Fig.15 In the sixth embodiment shown, the multiple light mixing surfaces of the light mixing element 2 are constructed by planes, and the light mixing element 2 forms a rectangular tube structure.

[0085] Further, the multiple light mixing surfaces of the light mixing element 2 are composed of a concave surface / convex surface and a flat surface. In other words, the multiple light mixing surfaces of the light mixing element 2 are composed of a concave surface and a flat surface or a convex surface and a flat surface.

[0086] Furthermore, the outer contour line of any one of the light incident surface and the light emitting surface includes a curve, and the outer contour line of the other surface includes at least two line segments, so as to ensure that the light mixing surface includes at least two planes.

[0087] Furthermore, when the mixed light surface is a convex surface, the convex surface radius r1 satisfies the relationship: r1≤1mm.

[0088] Since the convex surface can shrink the incident light after being reflected on the light mixing surface, the brightness is improved. Considering that the light mixing element 2 is composed of multiple light mixing surfaces, the convex surface radius is limited to within 1 mm to ensure good light uniformity and light intensity.

[0089] Furthermore, when the light mixing surface is a concave surface, the radius r2 of the concave surface satisfies the relationship: 6mm≤r2≤10mm.

[0090] Limiting the concave radius to within 6mm-10mm can ensure good light uniformity and light intensity.

[0091] Furthermore, the light mixing surface extends from the light incident surface, along the light mixing element 2 , to one end close to the light guide blade 1 .

[0092] Furthermore, the light source element 3 includes a first light source, a second light source and a third light source of different light colors, and the first light source and the second light source emit a first light ray, a second light ray and a third light ray respectively.

[0093] Thus, the light source 3 may include three-color light sources of R (red), G (green), and B (blue).

[0094] Furthermore, the first light, the second light and the third light enter the light mixing element 2 in the state of parallel light.

[0095] Furthermore, the cross-sectional shape of the reflective tooth 5 may be triangular, arc-shaped or hemispherical.

[0096] Preferably, the cross-sectional shape of the reflective tooth 5 is a triangle. The triangular reflective tooth 5 has the highest reflection efficiency and many adjustable parameters. The two angles where the triangle is connected to the back of the light-guiding blade 1 are adjustable. For example, the size of the incident angle can be adjusted by adjusting the inclination of the triangular tooth. At the same time, the direction of light emission can be controlled by adjusting the inclination of the triangular tooth. The structure is flexible and widely used.

[0097] The arc-shaped reflective teeth 5 have the widest reflection angle and low reflection efficiency, and are suitable for occasions where the brightness requirement is not high.

[0098] The reflectivity of the hemispherical reflective teeth 5 is also low, but the luminous area is large, so it is suitable for occasions that have high requirements on the luminous area but low requirements on the brightness.

[0099] The embodiment of the present invention adopts the triangular reflective teeth 5 to achieve a better atmosphere light effect.

[0100] like Figure 1As shown, the air outlet structure further includes: an air outlet shell 4 , the air outlet shell 4 is provided with an air outlet 41 , and both ends of the light guide blade 1 are movably connected to the air outlet shell 4 .

[0101] Thus, under the drive of a driving member such as a motor, the light guide blade 1 swings back and forth at the air outlet 41, thereby achieving different air outlet directions. Furthermore, when the light source member 3 is powered on, the light guide blade 1 can emit light while swinging, thereby presenting a crystal clear lighting effect in the vehicle.

[0102] In addition, the air outlet structure also includes: a sleeve, which is rotatably arranged on the air outlet housing 4, one end of the light guide fan blade 1 is fixed in the sleeve, and the light output end of the light mixing element 2 is arranged in the sleeve and opposite to the end of the light guide fan blade 1.

[0103] That is to say, the light guide blade 1 and the shaft sleeve are integrated, and the driving member such as a motor drives the shaft sleeve to rotate relative to the air outlet housing 4 to drive the light guide blade 1 to rotate together with the shaft sleeve. Since the light output end of the light mixing element 2 is arranged in the shaft sleeve, and there is a clearance fit between the light mixing element 2 and the shaft sleeve, and it is only clamped in the shaft sleeve, when the shaft sleeve rotates, the light mixing element 2 is stationary.

[0104] Furthermore, in order for the light guide fan blades 1 to realize the swinging function, they need excellent wear resistance. The mechanical strength can be improved by injecting glass fiber into the joints between the two ends of the light guide fan blades 1 and the air outlet shell 4, thereby increasing the wear resistance of the light guide fan blades 1 without affecting the overall transparency of the light guide fan blades 1.

[0105] Moreover, a plurality of groups of light guide blades 1 are provided at the air outlet 41 of the air outlet shell 4. The plurality of groups of light guide blades 1 are provided in parallel and arranged at intervals, thereby achieving a large-area ambient light effect at the air outlet 41 and enhancing the sense of interior design.

[0106] Furthermore, the light guide blade 1 is a colorless and transparent member, so that 360-degree light emission can be achieved.

[0107] The colorless and transparent transmittance of the light guide blade 1 may be required to reach 90% or above.

[0108] In the embodiment of the utility model, the light guide blade 1 is made of colorless and transparent PC or PMMA, which has the advantage of good light transmittance. PC is polycarbonate and PMMA is organic glass.

[0109] Furthermore, the light guide blades 1 are exposed at the air outlet 41 , and are configured to switch to different light modes according to different environments.

[0110] For example, the light-guiding fan blades 1 can be rotatably installed at the air outlet of the air conditioner so that the driver and passengers can see them directly.

[0111] When the air outlet temperature of the vehicle air conditioner is detected to be greater than the room temperature, the controller controls the color of the light guide blade 1 to be warm. When the air outlet temperature of the vehicle air conditioner is detected to be less than the room temperature, the controller controls the color of the light guide blade 1 to be cool. The light guide blade 1 provides feedback signals to the driver and passengers, providing a reminder of the actual working status of the air conditioner, enhancing the overall sense of technology and luxury of the vehicle, and further improving the riding comfort. For another example, the light guide blade 1 can also switch to different light modes according to the air volume at the air outlet 41.

[0112] A vehicle according to an embodiment of the second aspect of the utility model includes an air outlet structure.

[0113] Therefore, the fan blade function and the atmosphere light function are integrated into the light guide blade 1. The light guide blade 1 can not only rotate to achieve different air outlet directions, but also achieve the atmosphere light effect, and the structural parts of the light-transmitting cover are omitted, so that the light guide blade 1 is displayed at the air outlet 41 as an appearance part, with a novel shape, which can enhance the design sense of the vehicle body interior. At the same time, the structural parts such as the atmosphere light and the light-transmitting cover are omitted, and the structure becomes simple, which is convenient for installation. Moreover, by adjusting the parameters such as the reduction rate of the reflective teeth 5, the arrangement spacing, and the inclination angle of the reflective surface 6, it can be ensured that the light guide blade 1 can emit uniform and consistent light, which is relatively soft and convenient for passengers to watch.
