[0029] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present utility model. Unless otherwise specified, all technical and scientific terms used in the present utility model have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs.
[0030] Embodiment 1
[0031] In a typical implementation manner of the present utility model, as Figure 1 shown, a structure of an automotive interior atmosphere lamp is provided, as Figure 1-3As shown in the figure, it includes an ambient light 1, a light guide bar 2, a bright strip 3 on the lower side of the front door trim panel, and a decorative panel 4 in the middle of the front door trim panel; the ambient light 1 is snap-fitted into the light guide bar 2, and the light guide bar 2 is fixedly installed on the front door middle trim panel covering skeleton 5 through a light guide bar bracket 6; the bright strip 3 on the lower side of the front door trim panel is fixed on the front door middle trim panel covering skeleton 5 to block the light guide bar 2, and the upper surface of the decorative panel 4 in the middle of the front door trim panel is fixed on the door trim panel body as the irradiated surface.
[0032] In this embodiment, the ambient light 1 is cylindrical, a groove 201 is provided on the light guide bar 2, and the ambient light 1 is snap-fitted into the groove 201. Further, the groove 201 on the light guide bar 2 faces upward, the light guide bar 2 is in contact with the bright strip 3 on the lower side of the front door trim panel, and the bright strip 3 on the lower side of the front door trim panel blocks the light of the ambient light.
[0033] Further, the bright strip 3 on the lower side of the front door trim panel is an electroplated decorative strip, and the bright strip on the lower side of the front door trim panel is bent toward the position where the ambient light is located to block the light source emitted by the ambient light, so that the light source emitted by the ambient light cannot be directly seen by the naked eye.
[0034] Further, the bright strip 3 on the lower side of the front door trim panel is snap-connected to the front door middle trim panel covering skeleton 5 and fixed by self-tapping screws.
[0035] In this embodiment, the light guide bar 2 is snap-fitted into the guiding slot of the light guide bar bracket 6. The light guide bar bracket 6 is arranged along the outer edge of the front door trim panel skeleton 8. The light guide bar bracket 6 is fixed on the front door middle trim panel covering skeleton 8 by welding, which improves the installation stability of the light guide bar 2 and the ambient light 1. At the same time, the light guide bar 2 is snap-fitted around the ambient light 1, making it difficult for the ambient light to fall off from the groove of the light guide bar 2.
[0036] In order to achieve a better lighting effect, the test results of the material of the irradiated surface (the upper surface of the decorative surface 4 in the middle of the front door trim panel) are shown in Table 1:
[0037] Table 1 Selection of the material of the irradiated surface
[0038]
[0039]
[0040] Therefore, in this embodiment, the black PVC material with fine texture and light impermeability is used, which can achieve a better reflection effect.
[0041] In this embodiment, the upper surface of the decorative panel 4 in the middle of the front door trim panel is separated from the lower surface of the light guide bar 2 by a set distance, so that the light source reflected by the light guide bar 2 irradiates the upper surface of the decorative panel 4 in the middle of the front door trim panel to achieve the lighting effect.
[0042] In this embodiment, the ambient light includes a light strip 101, a lamp head 102, and a controller 103. The structure of the ambient light is prior art. After the LED in the lamp head is lit, the light is conducted through the light strip (the material is PMMA8N, and the optical transmittance is as high as 92.3%) to achieve light emission.
[0043] In this embodiment, the light guide bar adopts an existing light guide bar. The light emission principle of the light guide bar mainly relies on the phenomena of total reflection and refraction of light. By setting a light source on the side of the light guide bar, the light can propagate inside the light guide bar through total reflection and be released through specific outlets where needed to form a uniform lighting effect.
[0044] Therefore, the light emission principle of the automotive interior ambient light structure provided in this embodiment is as follows:
[0045] After the LED in the lamp head of the ambient light is lit, the light is conducted through the light strip to achieve light emission. The light emitted by the light strip is reflected by the light guide bar and irradiates on the upper surface of the decorative surface in the front door trim panel to achieve the light emission effect. At the same time, due to the shielding effect of the bright strip on the lower side of the front door trim panel, the light emitted by the ambient light strip cannot be seen inside the vehicle, and what is seen is the halo effect reflected by the light guide bar on the upper surface of the decorative surface in the front door trim panel.
[0046] The assembly and adjustment steps of the automotive interior ambient light structure provided in this embodiment are as follows:
[0047] 1. The light guide bar 2 is fixed in the guiding slot of the light guide bar bracket 6 by means of snap connection to ensure its orientation and fastening reliability.
[0048] 2. The light strip 101 of the ambient light 1 is snapped into the groove 201 of the light guide bar 2.
[0049] 3. The light guide bracket 6 is connected to the middle trim panel covering skeleton by ultrasonic welding.
[0050] 4. The bright strip 3 on the lower side of the front door trim panel is also fixed on the middle trim panel covering skeleton 5 in the form of M6 self-tapping screws and snap connection.
[0051] 5. The upper surface of the decorative panel 4 in the front door trim panel is finally fixed on the door trim panel body 7 as the illuminated surface.
[0052] Through the light-emitting form of this cooperation method, the irradiation angle can be adjusted by optical reflection, thereby changing the irradiation width, irradiation area, uniformity, and brightness. Specific methods: First, by adjusting the light guide bar bracket in the Z and Y directions (adjustment range ±2 mm), a larger light-emitting angle can be obtained. Second, by adjusting the irradiated surface (adjustment range ±15°), a larger light-emitting surface can be obtained. Combining the adjustments of the first and second methods can obtain different light-emitting effects and light-emitting ranges. Through optical simulation analysis, the most suitable position and the angle of the light-emitting surface are selected. According to this light-emitting form for optical simulation, various light-emitting effects can be obtained, such as Figure 5 As shown, finally, the brightness of the horizontal section of the irradiated surface simulated from the driver's perspective is about 2 nit, and the uniformity of the horizontal section of the irradiated surface is about 92%. Through the verification of the light-emitting effect of the actual vehicle, it is evaluated that the overall light-emitting effect level is relatively good.
[0053] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
