Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automotive interior atmosphere lamp, and in particular to an automotive door guard plate atmosphere lamp and a working method. BACKGROUND

[0002] As an important decorative element of automotive interior, the automotive door guard plate atmosphere lamp mainly achieves the creation and beautification of the atmosphere in the car by setting specific light sources and optical structures on the door guard plate. The working principle is to use the light emitted by the light source to uniformly distribute the light in the specific area of the door guard plate through light guiding, reflection, and diffuse reflection, thereby forming multi-color atmosphere lamps with different effects such as direct type and waterfall type.

[0003] At present, there are several common automotive door guard plate atmosphere lamp schemes: Type one: direct type multi-color atmosphere lamp is realized by transmitting the light source to the surface of the product through a PC milky white support. In this scheme, the light emitted by the light source is conducted through the PC milky white support and directly irradiates the surface of the door guard plate, forming a direct type atmosphere lamp effect. Type two: surface light source is realized by using multiple RGB lamp beads. This scheme uses multiple RGB lamp beads to form a surface light source, and achieves a multi-color atmosphere lamp effect by controlling the color and brightness of the lamp beads. Form three: in the patent CN119123360A, a "two-place" light effect is achieved through a milky white light-transmitting support in an automotive instrument panel atmosphere lamp.

[0004] The above-mentioned atmosphere lamp schemes have the following technical problems: the direct type multi-color atmosphere lamp is realized by a PC milky white support, which has a single atmosphere lamp effect and lacks diversity and level, making it difficult to meet the individualization and diversification needs of consumers for the atmosphere lamp in the car. Although the surface light source realized by multiple RGB lamp beads has a good atmosphere lamp effect, the cost is high, which increases the cost of automotive interior and is not conducive to market promotion and application. The two-place light effect is achieved through a milky white light-transmitting support, but the light intensity is greatly lost, the atmosphere lamp effect is poor, and a separate atmosphere lamp support is needed, which is not structurally firm and reliable. SUMMARY

[0005] In view of the deficiencies of the prior art, the purpose of the embodiments of the present application is to provide an automotive door guard plate atmosphere lamp, which optimizes the structure design and optical principle, improves the brightness of the atmosphere lamp, improves the presentation effect of the atmosphere lamp in the car, and at the same time ensures the firmness and reliability of the structure.

[0006] In order to achieve the above-mentioned purpose, the embodiments of the present application provide the following technical solutions:

[0007] The automobile door guard plate atmosphere lamp comprises a cladding assembly, an atmosphere lamp support, a light guide strip and an LED module; the upper side of the cladding assembly has a notch, and the surface of the cladding assembly at the lower side of the notch has an inclined convex surface; the atmosphere lamp support is installed at the notch of the cladding assembly, and the atmosphere lamp support comprises a light-transmitting support and a plated decorative ring, the light-transmitting support is installed at the bottom side of the plated decorative ring, the light-transmitting support has an open slot, the opening of the open slot is directed to the convex surface of the cladding assembly, the light guide strip is installed in the open slot, and one end of the light guide strip is inserted into the light-emitting hole of the LED module.

[0008] Optionally, the cladding assembly comprises a cladding framework and a cladding skin, the upper side of the cladding framework forms a notch structure, the lower side of the notch structure is convex to the outside, and the cladding skin covers the outer surface of the cladding framework to form the convex surface. The inclination angle of the convex surface is optimized to ensure that the light emitted by the light guide strip forms a waterfall light effect after being reflected by the skin.

[0009] Optionally, the cladding framework is formed by injection molding to ensure structural strength and light weight, and the cladding skin is adhered to the surface of the cladding framework by glue. The skin and the framework are tightly attached. This process can avoid the assembly gap caused by the traditional clamping method, thereby reducing light leakage and improving the uniformity of the waterfall light effect.

[0010] Optionally, the light-transmitting support is in a shape of a Chinese character "fang", the inner side of the "fang" shape forms an open slot, the direction of the open slot is at a preset angle with the convex surface, so that the light emitted by the light guide strip is projected to the convex surface for diffuse reflection through the open slot.

[0011] Optionally, the atmosphere lamp support is made by a double-color injection molding and plating process, and the manufacturing process is as follows: first, the light-transmitting support is formed by injection molding in a mold, then the plated decorative ring is formed by injection molding after the mold is rotated, the light-transmitting support and the plated decorative ring are combined together in the mold, the injection molding is completed, then heating and baking are performed, and finally the surface is plated. This process eliminates the traditional assembly steps, eliminates the fitting gap between the light-transmitting support and the decorative ring, and at the same time, the plated decorative ring directly serves as a decorative surface without the need for an additional spraying process.

[0012] Optionally, the atmosphere lamp support and the cladding assembly are fixed by hot riveting, which avoids the interference of metal parts to the light path and has higher shock resistance and sealing performance compared with bolt connection.

[0013] Optionally, the automobile door guard plate atmosphere lamp further comprises an LED module, the LED module comprises a module shell, a PCBA assembly and a module rear cover, the module shell and the module rear cover are installed together and form a cavity inside, the PCBA assembly is installed in the cavity, and the light guide strip is inserted into the module shell.

[0014] Optionally, the inner side of the module rear cover is provided with a buckle structure, and the side wall of the module shell is provided with a clamping groove, and the buckle structure of the module rear cover is inserted into the clamping groove of the module shell. This design allows quick disassembly and assembly, facilitating the maintenance or replacement of the PCBA assembly, and the elastic deformation of the buckle can compensate for the tolerance of the injection molding part, ensuring the close fit of the shell and the rear cover.

[0015] Optionally, the module rear cover is further provided with a support rib, which is arranged on the inner side of the module rear cover and fixes the PCBA assembly inside the module shell. When the rear cover is assembled with the shell, the support rib presses the PCBA assembly to prevent it from shifting in vibration.

[0016] The application also provides a working method of the automobile door guard plate atmosphere lamp, comprising: the light guide strip changes the light emitted by the LED module from a point light source into a columnar line light source; the light emitted by the light guide strip irradiates the light-transmitting support of the atmosphere lamp support, and the light-transmitting support transmits the light emitted by the light guide strip to the product surface to realize the direct type multi-color atmosphere lamp; meanwhile, the light emitted by the light guide strip irradiates the convex surface of the cladding assembly through the opening groove of the light-transmitting support, and the convex surface diffusely reflects the light emitted by the light guide strip to realize the waterfall type multi-color atmosphere lamp.

[0017] The one or more technical solutions provided in the embodiments of the application have at least the following technical effects or advantages:

[0018] 1. The automobile door guard plate atmosphere lamp comprises a cladding assembly, an atmosphere lamp support, a light guide strip and an LED module, the upper side of the cladding assembly is provided with a gap, an inclined convex surface is formed below the gap for guiding the light reflection path, the atmosphere lamp support is installed at the gap and comprises a light-transmitting support and a plated decorative ring, an opening groove is formed in the bottom of the light-transmitting support, and the opening direction corresponds to the convex surface of the cladding assembly, the light guide strip is embedded in the opening groove, and one end of the light guide strip is inserted into the light outlet hole of the LED module to form a complete light path from the light source to the light effect surface. This structure converts the point light source into a line light source through the light guide strip, and simultaneously realizes the direct type and the diffused reflection type double-mode light effect by using the light-transmitting support and the convex surface respectively. Compared with the prior art, the present application combines the light guide strip and the diffused reflection skin to simultaneously form the direct type and the waterfall type multi-color light effect, thereby improving the visual effect. The reflective atmosphere lamp directly irradiates on the convex surface, reduces the light loss and improves the brightness of the reflective atmosphere lamp. Moreover, only a single LED module is needed to realize the double-mode light effect, avoiding the multi-lamp bead configuration and significantly reducing the hardware cost.

[0019] 2. The wire harness assembly supplies power and controls the LED module to light up and emit light, the light emitted by the LED module passes through the light guide strip, the light guide strip extends the light emitting length of the LED module and increases the uniformity of light emission, the PC light transmission support transmits the light emitted by the light guide strip to the product surface to realize direct type multi-color atmosphere lamp, the coated PVC skin diffusely reflects the light emitted by the light guide strip to realize waterfall type multi-color atmosphere lamp, one LED module (one chip and one RGB lamp bead) is used to realize direct type and waterfall type multi-color atmosphere lamp at the same time, the cost is low, and the atmosphere lamp effect is good.

[0030] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] Example 1

[0032] like Figure 1 As shown, this embodiment proposes an ambient light for automotive door panels, including: a covering assembly 5, an ambient light bracket 4, a light guide strip 3, and an LED module 2; as shown... Figure 3 , Figure 4 As shown, the upper side of the covering assembly 5 has a notch, and the surface of the covering assembly 5 below the notch has an inclined protruding surface. The ambient light bracket 4 is installed at the notch of the covering assembly 5. The ambient light bracket 4 includes a light-transmitting bracket 42 and an electroplated decorative ring 41. The light-transmitting bracket 42 is installed on the bottom side of the electroplated decorative ring 41. The light-transmitting bracket 42 has an opening groove, the opening of which faces the protruding surface of the covering assembly 5. The light guide strip 3 is installed in the opening groove, and one end of the light guide strip 3 is inserted into the light emission hole of the LED module 2. The light guide strip 3 is injection molded from high-transparency PMMA material to guide the light emitted by the LED module 2 and project it onto the surface of the milky white light-transmitting PC bracket and the covering assembly 5.

[0033] Through the coordinated operation of the enclosure assembly 5, ambient light bracket 4, light guide strip 3, and LED module 2, both direct and waterfall-style multi-color ambient lighting effects are achieved. The notches and protruding surfaces of the enclosure assembly 5 provide installation space and reflective surfaces for the ambient light. The light-transmitting bracket 42 and electroplated trim ring 41 of the ambient light bracket 4 not only enhance structural stability but also precisely position the light guide strip 3 through the opening slot, allowing one end to be inserted into the light outlet of the LED module 2, ensuring effective light transmission and diffusion, and improving the brightness and aesthetics of the interior ambient lighting.

[0034] The covering assembly 5 includes a covering skeleton 52 and a covering skin 51, the upper side of the covering skeleton 52 forms a notched structure, the lower side of the notched structure protrudes outward, and the covering skin 51 covers the outer surface of the covering skeleton 52 to form the protruding surface. The design of the notched structure of the covering skeleton 52 and the outward protrusion provides a precise installation position and stable support for the ambient light assembly. The covering skin 51 covers the outer surface of the covering skeleton 52 to form the protruding surface, not only improving the appearance quality of the door guard plate, but also serving as a diffuse reflection surface to uniformly reflect the light emitted by the light guide strip 3 into the vehicle, achieving a waterfall multi-color ambient light effect and enhancing the level and comfort of the ambient light in the vehicle.

[0035] The covering skeleton 52 is made of ABS material and is injection molded to provide an installation carrier for the wire harness assembly 1 and the LED module 2 (as shown in Figure 5 The manual covering uses a 1mm PVC + 2mm PU foam skin to provide a diffuse reflection surface for the ambient light, diffuse the light emitted by the light guide strip 3 to achieve a waterfall multi-color ambient light, and improve the sense of technology and atmosphere of the whole vehicle.

[0036] The covering skeleton 52 is injection molded to ensure the accuracy of its shape and structural strength. The covering skin 51 is adhered to the surface of the covering skeleton 52 by glue. This connection is firm and reliable, avoiding the phenomenon of skin peeling or warping during use. At the same time, the injection molded covering skeleton 52 has good dimensional stability and surface flatness, providing a flat bonding basis for the covering skin 51, ensuring the overall aesthetics and uniform diffuse reflection effect of the door guard plate.

[0037] The light-transmitting bracket 42 is in a shape of a Chinese character "fang", the inner side of the "fang" shape forms an open slot, and the open slot is at a preset angle with the protruding surface, so that the light guide strip 3 can be installed in the open slot at a specific angle, and the light emitted by the LED module 2 is conducted to the protruding surface of the light-transmitting bracket 42 and the covering assembly 5 in the best path. By adjusting the preset angle, the propagation direction and distribution range of the light can be optimized, thereby realizing precise control of direct and waterfall multi-color ambient light and improving the uniformity and visual effect of the ambient light in the vehicle.

[0038] The ambient light bracket 4 is made of double-color injection molding and electroplating process, uses white light-transmitting PC and electroplated PC / ABS double-color injection molding, provides an installation carrier for the light guide strip 3 and the LED module 2, the PC / ABS electroplated part is a decorative ring, and the PC part is the light-transmitting bracket 42 and the direct ambient light.

[0039] The manufacturing process of dual-color injection molding and electroplating is as follows: First, a PC light-transmitting bracket 42 is injection molded in a mold. Then, the mold is rotated 180° and a PC / ABS electroplated decorative ring 41 is injection molded, with the two combined within the mold. After injection molding, the PC stress is removed by heating and baking, and then the PC / ABS surface is electroplated. The PC / ABS electroplated decorative ring 41 has a metallic luster and a good decorative effect. The light-transmitting bracket 42 transmits the light emitted by the light guide strip 3 to the product surface to achieve direct-light multi-color ambient lighting, enhancing the overall technological and atmospheric feel of the vehicle.

[0040] The ambient light bracket 4 and the covering assembly 5 are fixed together by hot riveting welding, a connection method that offers high strength and stability. During the hot riveting welding process, high temperatures melt and tightly bond the materials at the connection points, forming a robust mechanical connection. During automotive use, this effectively resists vibration and impact, ensuring that the positional accuracy and optical performance of the ambient light components remain unaffected, thus guaranteeing the stability and durability of the ambient lighting effect inside the vehicle.

[0041] LED module 2 serves as the core light source for the ambient lighting, such as Figure 2 As shown, the system includes a module housing 21, a PCBA assembly 22, and a module rear cover 23. The PCBA board contains a single LED chip, providing an RGB light source for the ambient lighting and controlling the LED's color and brightness. The module housing 21 and the module rear cover 23 are mounted together, forming an internal cavity. The PCBA assembly 22 is installed within this cavity, providing a protective environment for the LED chip and preventing damage from external dust, moisture, etc. A light guide strip 3 is inserted into the module housing 21, ensuring effective light transmission. By controlling the circuitry on the PCBA assembly 22, the color and brightness of the LED chip can be precisely adjusted to achieve ambient lighting effects with various colors and brightness levels, meeting the needs of different users for the in-car atmosphere.

[0042] The inner side of the module back cover 23 is provided with a snap-fit ​​structure, and the side wall of the module housing 21 is provided with a snap-fit ​​groove. The snap-fit ​​structure of the module back cover 23 is inserted into the snap-fit ​​groove of the module housing 21. This snap-fit ​​connection method is simple to operate, requiring no additional screws or glue or other connectors, thus improving the assembly efficiency of the LED module 2. At the same time, the snap-fit ​​connection has good detachability, allowing the module back cover 23 to be quickly removed for inspection and maintenance of the PCBA assembly 22 or the module housing 21 when maintenance or component replacement is required, reducing maintenance costs and time.

[0043] The module rear cover 23 is also provided with support ribs, which are located on the inner side of the module rear cover 23. The support ribs fix the PCBA assembly 22 inside the module housing 21. This design ensures the stable position of the PCBA assembly 22 within the module housing 21, preventing the PCBA assembly 22 from loosening or shifting due to vibration during vehicle operation, which would affect the light-emitting performance of the LED chips and the electrical connection of the module.

[0044] Example 2

[0045] This embodiment provides a method for operating the automotive door panel ambient light as described above, including:

[0046] The light guide strip 3 changes the light emitted by the LED module 2 from a point light source to a columnar line light source;

[0047] The light emitted by the light guide strip 3 shines on the light-transmitting bracket 42 of the ambient light bracket 4. The light-transmitting bracket 42 propagates the light emitted by the light guide strip 3 to the product surface to achieve direct multi-color ambient lighting. At the same time, the light emitted by the light guide strip 3 shines on the protruding surface of the covering assembly 5 through the opening groove of the light-transmitting bracket 42. The protruding surface diffuses the light emitted by the light guide strip 3 to achieve waterfall-style multi-color ambient lighting.

[0048] like Figure 6 As shown, the light guide strip 3 transforms the point light source emitted by the LED module 2 into a columnar line light source, increasing the propagation path and coverage of the light. The light emitted from the light guide strip 3 illuminates the light-transmitting bracket 42 of the ambient light holder 4, which then propagates the light to the product surface, forming a direct-beam multi-color ambient light. Simultaneously, the light passes through the opening slot of the light-transmitting bracket 42 and illuminates the protruding surface of the covering assembly 5, where it diffuses the light, achieving a waterfall-style multi-color ambient light. This method fully utilizes the propagation and reflection characteristics of light, achieving an organic combination of direct and waterfall-style ambient lighting effects through single light transmission and double light utilization. This enhances the layering and aesthetics of the in-car ambient lighting, creating a comfortable and personalized in-car environment for passengers. Figure 7 The image shown is a schematic diagram of the ambient lighting effect.

[0049] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
