Description

Technical Field

[0001] The present invention relates to the technical field of automobile interior atmosphere lamps, and in particular to an automobile door guard plate atmosphere lamp and a working method thereof. Background Art

[0002] As an important decorative element of car interior, the car door panel atmosphere light mainly creates and beautifies the atmosphere inside the car by setting a specific light source and optical structure on the door panel. Its working principle is to use the light emitted by the light source to evenly distribute the light in a specific area of ​​the door panel through optical effects such as light guidance, reflection, and diffuse reflection, thereby forming a multi-color atmosphere light with different effects such as direct and waterfall.

[0003] At present, there are several common solutions for car door panel atmosphere lights: Type 1: Use a PC milky white bracket to spread the light source to the product surface to achieve a direct multi-color atmosphere light. In this solution, the light emitted by the light source is transmitted through the PC milky white bracket and directly shines on the surface of the door panel to form a direct atmosphere light effect. Type 2: Use multiple RGB lamp beads to achieve a surface light source. This solution uses multiple RGB lamp beads to form a surface light source, and achieves a multi-color atmosphere light effect by controlling the color and brightness of the lamp beads. Form 3: Patent CN119123360A, a car dashboard atmosphere light, uses a milky white light-transmitting bracket to achieve a "two-place" lighting effect.

[0004] The above-mentioned atmosphere light scheme has the following technical problems: The direct multi-color atmosphere light is realized through the PC milky white bracket, and its atmosphere light effect is single, lacking diversity and layering, and it is difficult to meet consumers' personalized and diversified needs for in-car atmosphere lights. The surface light source is realized through multiple RGB lamp beads. Although the atmosphere light effect is better, the cost is high, which increases the cost of car interior and is not conducive to market promotion and application. The milky white light-transmitting bracket is used to achieve two lighting effects, but this solution has a large loss of light brightness, the atmosphere light effect is poor, and a separate atmosphere light bracket is required, and the structure is not strong and reliable enough. Summary of the invention

[0005] In view of the deficiencies in the prior art, an embodiment of the present invention aims to provide a car door panel atmosphere light, which improves the brightness of the atmosphere light and the effect of the interior atmosphere light by optimizing the structural design and optical principles, while ensuring the firmness and reliability of the structure.

[0006] In order to achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

[0007] A car door panel atmosphere light, comprising: a covering assembly, an atmosphere light bracket, a light guide strip and an LED module; the upper side of the covering assembly has a notch, and the surface of the covering assembly below the notch has an inclined protruding surface; the atmosphere light bracket is installed at the notch of the covering assembly, the atmosphere light bracket comprises a light-transmitting bracket and an electroplated decorative ring, the light-transmitting bracket is installed on the bottom side of the electroplated decorative ring, the light-transmitting bracket has an open groove, the opening of the open groove faces the protruding surface of the covering assembly, the light guide strip is installed in the open groove, and one end of the light guide strip is inserted into the light outlet hole of the LED module.

[0008] Optionally, the covering assembly includes a covering frame and a covering skin, the upper side of the covering frame forms a notch structure, the lower side of the notch structure protrudes outward, and the covering skin covers the outer surface of the covering frame to form the protruding surface. The inclination angle of the protruding surface is optimized to ensure that the light emitted by the light guide bar forms a waterfall light effect after being reflected by the skin.

[0009] Optionally, the coating frame is injection molded to ensure structural strength and lightness, and the coating skin is coated on the surface of the coating frame by gluing. This allows the skin to fit tightly with the frame. This process can avoid assembly gaps caused by traditional clamping methods, thereby reducing light leakage and improving the uniformity of waterfall-style light effects.

[0010] Optionally, the light-transmitting bracket is a U-shaped structure, an open groove is formed on the inner side of the U-shaped structure, and the direction of the open groove forms a preset angle with the protruding surface, so that the light emitted by the light guide strip is projected onto the protruding surface through the open groove for diffuse reflection.

[0011] Optionally, the ambient light bracket is made by two-color injection molding plus electroplating process, and its manufacturing process is as follows: first, the light-transmitting bracket is injection molded in the mold, the mold is rotated and then the electroplated decorative ring is injection molded, the light-transmitting bracket and the electroplated decorative ring are combined together in the mold, and after the injection molding is completed, they are heated and baked, and then the surface is electroplated. This process omits the traditional assembly steps, eliminates the matching gap between the light-transmitting bracket and the decorative ring, and the electroplated decorative ring is directly used as a decorative surface without the need for an additional spraying process.

[0012] Optionally, the ambient light bracket and the covering assembly are fixed by hot riveting. Compared with bolt connection, this method avoids the interference of metal parts on the light path and has higher shock resistance and sealing.

[0013] Optionally, the automobile door panel atmosphere light also includes an LED module, which includes a module shell, a PCBA assembly and a module back cover. The module shell and the module back cover are installed together and form a cavity inside. The PCBA assembly is installed in the cavity, and the light guide strip is plugged into the module shell.

[0014] Optionally, a buckle structure is provided on the inner side of the module back cover, a slot is provided on the side wall of the module housing, and the buckle structure of the module back cover is inserted into the slot of the module housing. This design allows for quick disassembly and assembly, facilitating maintenance or replacement of the PCBA assembly, while the elastic deformation of the buckle can compensate for the tolerance of the injection molded parts, ensuring a tight fit between the housing and the back cover.

[0015] Optionally, the module rear cover is further provided with support ribs, which are provided on the inner side of the module rear cover, and the support ribs fix the PCBA assembly inside the module housing. When the rear cover is assembled with the housing, the support ribs press the PCBA assembly to prevent it from shifting during vibration.

[0016] The present invention also provides a working method of the automobile door panel atmosphere light as described above, comprising: a light guide bar 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 bar is irradiated onto a light-transmitting bracket of the atmosphere light bracket, and the light-transmitting bracket transmits the light emitted by the light guide bar to the product surface to realize a direct-type multi-color atmosphere light; at the same time, the light emitted by the light guide bar is irradiated onto the protruding surface of the covering assembly through the opening groove of the light-transmitting bracket, and the protruding surface diffusely reflects the light emitted by the light guide bar to realize a waterfall-type multi-color atmosphere light.

[0017] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0018] 1. The automotive door guard plate atmosphere lamp of the present invention comprises a covering assembly, an atmosphere lamp bracket, a light guide bar and an LED module. A notch is provided on the upper side of the covering assembly, and an inclined protruding surface is formed below the notch to guide the light reflection path. The atmosphere lamp bracket is installed at the notch, and is composed of a light-transmitting bracket and an electroplated decorative ring. An opening groove is provided at the bottom of the light-transmitting bracket, and the opening direction corresponds to the protruding surface of the covering assembly. The light guide bar is embedded in the opening groove, and one end of the light guide bar 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. The structure converts a point light source into a line light source through the light guide bar, and at the same time uses the light-transmitting bracket and the protruding surface to respectively realize direct and diffuse reflection dual-mode light effects. Compared with the prior art, the present invention combines the light guide bar with the diffuse reflection epidermis to simultaneously form direct and waterfall multi-color light effects, thereby improving the visual effect. The reflective atmosphere lamp is directly irradiated on the protruding surface, reducing light loss and improving the brightness of the reflective atmosphere lamp. Moreover, only a single LED module is required to achieve dual-mode light effects, avoiding the configuration of multiple lamp beads, and significantly reducing hardware costs.

[0019] 2. The wiring 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 bar, which extends the light-emitting length of the LED module and increases the uniformity of the light. The PC light-transmitting bracket transmits the light emitted by the light guide bar to the surface of the product to realize direct multi-color atmosphere light. The PVC-coated surface diffusely reflects the light emitted by the light guide bar to realize waterfall-type multi-color atmosphere light. One LED module (one chip and one RGB lamp bead) is used to realize both direct and waterfall-type multi-color atmosphere lights, with low cost and good atmosphere light effect.

[0030] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates 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 automotive door panel atmosphere lamp, including: a covering assembly 5, an atmosphere lamp bracket 4, a light guide bar 3 and an LED module 2; 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 convex surface; the atmosphere lamp bracket 4 is installed at the notch of the covering assembly 5, and the atmosphere lamp bracket 4 includes a light-transmitting bracket 42 and a plated decorative ring 41. The light-transmitting bracket 42 is installed on the bottom side of the plated decorative ring 41, and the light-transmitting bracket 42 has an open groove, and the opening of the open groove faces the convex surface of the covering assembly 5. The light guide bar 3 is installed in the open groove, and one end of the light guide bar 3 is inserted into the light outlet hole of the LED module 2. The light guide bar 3 is injection molded with a highly transparent PMMA material to guide the light emitted by the LED module 2 and hit the surface of the milky white light-transmitting PC bracket and the covering assembly 5.

[0033] Through the coordinated work of the covering assembly 5, the ambient light bracket 4, the light guide bar 3 and the LED module 2, the direct and waterfall multi-color ambient light effects are achieved. The notch and protruding surface of the covering assembly 5 provide installation space and reflection surface for the ambient light, and the light-transmitting bracket 42 and the electroplated decorative ring 41 of the ambient light bracket 4 not only enhance the structural stability, but also accurately position the light guide bar 3 through the opening groove, so that one end of the light guide bar 3 is inserted into the light outlet hole of the LED module 2, ensuring the effective conduction and diffusion of light, and improving the brightness and aesthetics of the ambient light in the car.

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

[0035] The covering frame 52 is made of ABS material by injection molding, and provides a mounting carrier (such as Figure 5 As shown), the hand-wrapped surface uses 1mmPVC+2mmPUfoam to provide a diffuse reflection surface for the atmosphere light. The light emitted by the diffuse reflection light guide strip 3 realizes a waterfall-style multi-color atmosphere light, enhancing the sense of technology and atmosphere of the entire vehicle.

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

[0037] The light-transmitting bracket 42 is a U-shaped structure, and an open groove is formed inside the U-shaped structure. The direction of the open groove forms a preset angle with the protruding surface, so that the light guide bar 3 can be installed in the open groove at a specific angle, and the light emitted by the LED module 2 is transmitted to the light-transmitting bracket 42 and the protruding surface of the covering assembly 5 in an optimal path. By adjusting the preset angle, the propagation direction and distribution range of the light can be optimized, thereby achieving precise control of the direct and waterfall multi-color atmosphere lights, and improving the uniformity and visual effect of the interior atmosphere lights.

[0038] The atmosphere light bracket 4 is made by two-color injection molding and electroplating process, using milky white translucent PC and electroplating grade PC / ABS for two-color injection molding, providing an installation carrier for the light guide bar 3 and the LED module 2. The PC / ABS electroplating part is a decorative ring, and the PC part is a translucent bracket 42 and a direct atmosphere light.

[0039] The manufacturing process of two-color injection molding plus electroplating is as follows: first, the PC light-transmitting bracket 42 is injection molded in the mold, and the mold is rotated 180 degrees to inject and mold the PC / ABS electroplated decorative ring 41, and the two are combined together in the mold. After the injection molding is completed, 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 bar 3 to the product surface to realize a direct multi-color atmosphere light, which enhances the sense of technology and atmosphere of the whole vehicle.

[0040] The ambient light bracket 4 and the covering assembly 5 are fixed by hot riveting welding, which has high strength and stability. During the hot riveting welding process, the materials of the connection parts are melted and tightly combined by high temperature to form a strong mechanical connection. During the use of the car, it can effectively resist vibration and impact, ensure that the position accuracy and optical performance of the ambient light assembly are not affected, and ensure the stability and durability of the ambient light effect in the car.

[0041] LED module 2 is used as the core light source of the atmosphere light. Figure 2 As shown, it includes a module housing 21, a PCBA assembly 22 and a module back cover 23. The PCBA board contains a luminous LED particle, which provides an RGB light source for the atmosphere light and controls the color and brightness of the LED. The module housing 21 and the module back cover 23 are installed together to form a cavity inside. The PCBA assembly 22 is installed in the cavity, which provides a good protective environment for the LED particles to prevent damage to them by external dust, moisture, etc. The light guide bar 3 is plugged into the module housing 21 to ensure the effective conduction of light. By controlling the circuit on the PCBA assembly 22, the color and brightness of the LED particles can be accurately adjusted to achieve atmosphere light effects of various colors and brightness levels to meet the needs of different users for the atmosphere in the car.

[0042] The inner side of the module back cover 23 is provided with a snap-on structure, and the side wall of the module housing 21 is provided with a snap-on slot, and the snap-on structure of the module back cover 23 is inserted into the snap-on slot of the module housing 21. This snap-on connection is easy to operate and does not require additional connectors such as screws or glue, thereby improving the assembly efficiency of the LED module 2. At the same time, the snap-on connection has good detachability. When maintenance or replacement of parts is required, the module back cover 23 can be quickly disassembled, and the PCBA assembly 22 or the module housing 21 can be inspected and maintained, thereby reducing maintenance costs and time.

[0043] The module rear cover 23 is also provided with support ribs, which are provided on the inner side of the module rear cover 23, and fix the PCBA assembly 22 inside the module housing 21. This design ensures the stable position of the PCBA assembly 22 inside the module housing 21, and avoids the PCBA assembly 22 from loosening or shifting due to vibration during the driving of the car, which affects the luminous performance of the LED particles 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, comprising:

[0046] The light guide bar 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 bar 3 is irradiated onto the light-transmitting bracket 42 of the atmosphere light bracket 4, and the light-transmitting bracket 42 transmits the light emitted by the light guide bar 3 to the surface of the product to realize a direct-type multi-color atmosphere light; at the same time, the light emitted by the light guide bar 3 is irradiated onto the protruding surface of the covering assembly 5 through the opening groove of the light-transmitting bracket 42, and the protruding surface diffusely reflects the light emitted by the light guide bar 3 to realize a waterfall-type multi-color atmosphere light.

[0048] like Figure 6 As shown, the light guide bar 3 changes the point light source emitted by the LED module 2 into a columnar line light source, increasing the light propagation path and coverage range. On the one hand, the light emitted by the light guide bar 3 shines on the light-transmitting bracket 42 of the atmosphere light bracket 4, and the light-transmitting bracket 42 transmits the light to the product surface to form a direct-type multi-color atmosphere light; on the other hand, the light passes through the open groove of the light-transmitting bracket 42 and shines on the protruding surface of the covering assembly 5, and the protruding surface diffusely reflects the light to achieve a waterfall-type multi-color atmosphere light. This working method makes full use of the propagation and reflection characteristics of light. Through one-time light conduction and two-time light utilization, it realizes the organic combination of direct and waterfall-type atmosphere light effects, enhances the layering and aesthetics of the interior atmosphere light, and creates a comfortable and personalized interior environment for drivers and passengers. As shown Figure 7 The figure shows a schematic diagram of the atmosphere light effect.

[0049] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it 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 on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
