Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to a thick-walled automotive lighting fixture. Background Technology

[0002] Currently, as an important automotive technology, automotive lights are undergoing round after round of innovation and transformation along with the development of automobiles and the progress of technology. The appearance of automotive lights and customer requirements are also improving rapidly with the automotive industry. Among them, thick-walled shapes have become a design hotspot due to their combination of technological feel and three-dimensionality.

[0003] Existing mature solutions can be roughly divided into two types: one is a light source + thick-walled component + lampshade structure, which requires less space, but the optical uniformity is difficult to meet the requirements and cannot meet the high-quality optical requirements; the other is a light source + thick-walled component + thick-walled component + lampshade structure, which can improve the uniformity of light effect, but the stacking of multiple thick-walled components leads to an increase in volume, which makes it less adaptable to lamps with small depth space and difficult to promote its application in compact car lights.

[0004] Both of the above solutions suffer from the problem of balancing optical performance and spatial adaptability, a contradiction that is even more pronounced in the context of increasingly compact automotive front cabin layouts. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to resolve the contradiction between optical uniformity and installation space in existing thick-walled automotive lamps, this utility model provides a thick-walled automotive lamp by proposing an external thick-walled component solution, which utilizes external space to achieve a three-dimensional expression of the thick-walled shape, while freeing up internal installation space and reducing dependence on the depth dimension of the lamp.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a thick-walled automotive lamp, including a lamp cover and a light guide assembly, wherein the light guide assembly is detachably installed on the outside of the lamp cover; in: At least one groove is provided on the outer side of the lampshade; The light guide component includes a thick-walled member, one end of which is disposed in a groove, and the other end of which extends outward from the lampshade to form a three-dimensional structure.

[0007] Therefore, by placing the thick-walled component externally and embedding it into the lampshade groove, the optical structure and installation space are decoupled, effectively reducing the internal depth occupied by the lamp while ensuring the three-dimensional feel of the thick-walled shape. One end of the thick-walled component is fixed in the groove, while the other end extends cantilevered to form an external three-dimensional contour. The external space is used to extend the light path and visual expression, improving the optical uniformity. This structure is suitable for compact vehicle models, taking into account both the need for a high-quality appearance and the adaptability to a small installation environment, and solving the technical problem of mutual constraints between optical performance and structural space in traditional solutions.

[0008] Furthermore, the lampshade includes a light-transmitting part and a light-shielding part. The light-transmitting part is used for light output, while the light-shielding part blocks stray light and improves visual contrast. The light-transmitting part is recessed inward to form a groove with the light-shielding part. Compared with the existing solution that uses an external light shield or additional components to control the light path, this solution optimizes optical purity without increasing assembly complexity through structural integration design. The light-transmitting part and the light-shielding part are integrally molded using a two-color injection molding process, ensuring structural strength and clear optical boundaries. Compared with the existing two-color light distribution structure that requires bonding or splicing, this solution avoids optical offset caused by assembly errors, improves product consistency and yield, and simplifies the assembly process and reduces production costs.

[0009] Furthermore, the light-transmitting portion and / or the thick-walled portion are provided with patterns and textures to improve light efficiency, achieve uniform light effect and enhance appearance texture.

[0010] Furthermore, the light guide assembly also includes a fixing frame, which is disposed on one side of the thick-walled component. The end face of the fixing frame is detachably connected to the light-shielding part, facilitating the assembly and positioning of the thick-walled component and the lampshade. Thus, through the detachable connection structure of the fixing frame, precise alignment and rapid assembly of the thick-walled component within the groove are achieved, improving production efficiency and reducing assembly errors. At the same time, the fixing frame provides lateral support to the thick-walled component, enhancing the mechanical stability of the cantilever extension structure, effectively suppressing deformation caused by vibration or temperature changes, and ensuring long-term reliable optical performance.

[0011] Furthermore, the fixing frame and the thick-walled component are integrally formed; thereby reducing assembly interfaces, improving the overall structure and strength, and reducing the risk of optical path misalignment caused by loose connections; at the same time, it helps to simplify the production process, reduce the number of parts, improve the degree of modularity, and is suitable for automated assembly processes.

[0012] Furthermore, the light guide assembly also includes a protective cover, which is semi-enclosed on the exposed part of the thick-walled component. One end of the protective cover is fixedly connected to the lampshade. The protective cover has a transparent structure and is used for dustproof, waterproof and scratch-resistant purposes, and effectively isolates the external environment from the erosion of the optical surface, ensuring the stability of light output.

[0013] Furthermore, a micro-gap is reserved between the inner side of the protective cover and the thick-walled component to form an air insulation layer, which alleviates stress damage caused by thermal expansion differences.

[0014] Furthermore, a housing is detachably connected to the side of the lampshade away from the light guide component. The housing and the lampshade form a closed optical cavity, which effectively blocks the intrusion of external dust and moisture and improves the environmental tolerance of the lamp. An LED light source module is provided in the optical cavity, and the side of the LED light source module is detachably connected to the inside of the housing.

[0015] Furthermore, optical components for achieving uniform light distribution are also fixedly installed inside the optical cavity; The light-incident surface of the optical component is disposed on the light-out path of the LED light source module, and the light-incident surface of the thick-walled component is disposed on the light-out path of the optical component; the optical component is used to pre-collimate or diffuse the initial beam to optimize the light field distribution incident on the light guide component; thereby improving the light guiding efficiency and reducing light energy loss.

[0016] Furthermore, the optical component is an inner lampshade, which is made of a material with added diffusing particles. The side of the inner lampshade away from the LED light source module is provided with micro-patterns and / or textures. Thus, through the synergistic effect of the diffusing particles and the surface microstructure, the light efficiency is improved and a uniform light effect is achieved.

[0017] Furthermore, the optical component may also be a thick-walled structure, and the outer side of the thick-walled structure is provided with optical patterns, textures and / or aluminum plating.

[0018] Furthermore, the optical component may also be a reflector structure, with optical patterns, textures and / or an aluminum plating layer on the inner side of the reflector structure, used to control the angular distribution of reflected light and improve beam uniformity and utilization efficiency.

[0019] Furthermore, the groove is provided in multiple ways, and the multiple grooves are distributed circumferentially, linearly, or randomly on the outside of the lampshade, and the grooves correspond one-to-one with the light guide components; A decorative strip is provided between adjacent light guide components. Both ends of the decorative strip are fixedly connected to the lampshade. The decorative strip is used to partially conceal the mounting bracket and lampshade, and to enhance the overall styling and visual segmentation of the lamp, making each lighting unit clearly defined and its light zone independent. A decorative layer is provided on the outer side of the decorative strip. This layer features patterns, stripes, or surface treatment processes (such as hot stamping, painting, laser engraving, pad printing, or aluminum plating) to create an appearance that gives it rich texture and light and shadow layers, enhancing the aesthetic appeal of the lamp. Simultaneously, this decorative structure can echo the vehicle's design language, achieving harmony between the lighting components and the overall shape, strengthening brand recognition and visual memorability while ensuring functionality.

[0020] The beneficial effects of this utility model are that the thick-walled automotive lamp of this utility model connects the light guide component externally to the lamp cover, realizing a shape that cannot be achieved by the external lamp cover mold process, so that the light guide component is directly exposed to the external visible area, enhancing the three-dimensionality and technological feel of the light; compared with the traditional built-in light guide design, this utility model simplifies the internal space layout while ensuring uniform light effect, adapting to the needs of more compact modular assembly, and is especially suitable for the trend of automotive integrated design.

[0021] The thick-walled automotive lamp of this invention incorporates optical components within the optical cavity to optimize the optical path design and achieves highly uniform light output through multi-level control. The thick-walled components and optical components work synergistically to effectively suppress stray light and improve light utilization. Simultaneously, the composite design of materials and surface microstructures enables precise light field distribution, ensuring no light crosstalk between lighting units.

[0022] This utility model's thick-walled automotive lamp, combined with the external layout of the light guide component and the visual guiding effect of the decorative strip, enhances the sense of light layering and dynamic visual effect; the decorative strip can be detachably installed on the lamp cover, and through various surface treatments, it can meet the user's personalized appearance requirements.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0031] Example 1: like Figure 1 As shown, a thick-walled automotive lamp includes a lamp cover 1 and a light guide component 2. In this embodiment, there are two light guide components 2, which can be arranged symmetrically or asymmetrically. In this solution, the two light guide components 2 are arranged symmetrically about the center line of the lamp cover 1.

[0032] like Figure 2 , Figure 3 As shown, the light guide component 2 is installed on the outside of the lampshade 1 by screws. The other side of the lampshade 1 is snapped into the housing 4. An optical cavity is formed between the lampshade 1 and the housing 4. An LED light source module consisting of a PCB board 51 and an LED light source 52 is provided in the optical cavity. The PCB board 51 and the housing 4 are fixedly connected by an elastic snap-fit ​​structure or screw fastening. The LED light source 52 corresponds one-to-one with the light guide component 2. An optical element 6 is provided in the light output direction of the LED light source 52 for collimating and shaping the initial beam. The light input end of the light guide component 2 is set on the light output path of the optical element 6.

[0033] like Figure 1 , Figure 3 As shown, a decorative strip 3 is provided between the two light guide components 2. The decorative strip 3 extends along the horizontal center line of the lampshade 1, runs through the entire visual center of the lamp, and forms a horizontal visual guide line to enhance the sense of extension and technology of the front face. The two ends of the decorative strip 3 are fixedly connected to the lampshade 1 by snap-fit, adhesive or screw fastening.

[0034] in: Reference Figure 3The lampshade 1 includes a light-transmitting part 11 and a light-shielding part 12. The light-shielding part 12 can achieve light shielding through aluminum plating, painting, or opaque material. In this embodiment, the light-shielding part 12 is made of opaque material. The light-transmitting part 11 and the light-shielding part 12 are integrally formed by a two-color injection molding process. The light-transmitting part 11 is composed of component one and component two. Component one is correspondingly set with one of the light guide components 2, and component two is correspondingly set with the other light guide component 2. The light-shielding part 12 is composed of a connecting part and a middle part. The middle part is located between the two connecting parts. The connecting part is located on the side of the light-transmitting part 11 near the housing 4, and the outer end of the connecting part is snapped into the housing 4. Component one is located between one of the connecting parts and the middle part, and component two is located between the other connecting part and the middle part. The inner ends of component one and component two are recessed inward to form a groove that does not penetrate the lampshade with the middle part. The groove is used to place the light guide component 2. In order to ensure stability, in this embodiment, the middle part protrudes outward, so as to form two grooves with component one and component two.

[0035] Reference Figure 3 The light guide assembly 2 includes a thick-walled component 21, a fixing frame 22, and a protective cover 23. One end of the thick-walled component 21 is placed in a corresponding groove, and the other end of the thick-walled component 21 extends outward from the lampshade 1 to form a three-dimensional structure. The fixing frame 22 is integrally formed with the thick-walled component 21. The fixing frame 22 is located on the inward side of the thick-walled component 21 and is fixed to the middle part by screws, which realizes the precise alignment and rapid assembly of the thick-walled component 21 in the groove, improves production efficiency and reduces assembly errors. At the same time, the fixing frame 22 provides lateral support to the thick-walled component 21, enhances the mechanical stability of the cantilever extension structure, effectively suppresses deformation caused by vibration or temperature changes, and ensures long-term reliable optical performance. The protective cover 23 is semi-enclosed on the exposed part of the thick-walled component 21. One end of the protective cover 23 is fixedly connected to the light-transmitting part 11 by welding, snap-fitting or screw fastening. A micro gap is reserved between the inner side of the protective cover 23 and the thick-walled component 21 to form an air insulation layer to alleviate stress damage caused by thermal expansion differences. The protective cover 23 has a transparent structure to prevent dust, water and scratches, and effectively isolate the external environment from the erosion of the optical surface, ensuring the stability of light output.

[0036] The optical component 6 is an inner lampshade, which is made of a material with added diffusion particles. The inner lampshade can be fixedly connected to the housing 4, the lampshade 1, or the PCB board 51. In this embodiment, the inner lampshade is fixed by snapping the two ends of the inner lampshade to the PCB board 51. The LED light source 52 is located between the inner lampshade and the PCB board 51.

[0037] Decorative strip 3 is used to conceal and hide the fixing bracket 22 and the middle part, and enhances the overall styling and visual segmentation of the lamp, making the boundaries of each lighting unit clear and the light area independent. The outer side of decorative strip 3 is provided with a decorative layer, which is formed on a flat surface through surface treatment process, giving it a rich texture and light and shadow layers, and enhancing the aesthetic expression of the lamp; at the same time, this decorative structure can echo the design language of the vehicle body, achieving a harmonious unity between the lighting components and the overall shape, and strengthening brand recognition and visual memorability while ensuring functionality.

[0038] In addition, to enhance the uniform light effect, patterns and textures are provided on parts of the light-transmitting part 11, parts of the thick-walled part 21, and the side of the inner lampshade away from the LED light source module.

[0039] Thus, the light emitted by the LED light source 52 is scattered by the diffused particles on the inner surface of the inner lampshade, and then enters the thick-walled component 21 through the groove of the light-transmitting part 11. Finally, it is uniformly guided out by the exposed part of the thick-walled component 21. This utility model achieves a decoupling design between the optical structure and the installation space by placing the thick-walled component 21 externally and embedding it into the groove of the lampshade 1. While ensuring the three-dimensionality of the thick-walled shape, it effectively reduces the internal depth occupied by the lamp. The thick-walled component 21 is a cantilevered extension that forms an external three-dimensional contour. It uses the external space to complete the extension of the light path and visual expression, thereby improving the optical uniformity. This structure is suitable for vehicles with compact front cabin space, taking into account the high-quality appearance requirements and the adaptability of the narrow installation environment, and solving the technical problem of mutual constraints between optical performance and structural space in traditional solutions.

[0040] Example 2: Where assembly space permits, the structure of optical component 6 is optimized based on Example 1. The specific solution is as follows: like Figure 4 As shown, the optical component 6 is a thick-walled structure, and the outer side of the thick-walled structure is provided with optical patterns, textures, and / or aluminum plating. Thus, the lamp forms an optical path with double thick-walled component structures superimposed. After the light is initially diffused by the inner thick-walled component, it is then guided and homogenized a second time by the outer thick-walled component 21, improving the softness of the light and the overall uniformity.

[0041] Example 3: An alternative to Example 2, as follows: like Figure 5 As shown, the optical component 6 is a reflector structure, and its reflector structure corresponds one-to-one with the LED light source 52. The reflector structure can be fixedly connected to the housing 4 through the support structure, or integrated with the PCB board 51 to ensure accurate alignment of the light path. The inner side of the reflector structure is provided with optical patterns, textures and / or aluminum plating layers to adjust the angle distribution of reflected light and improve beam uniformity and utilization efficiency.

[0042] Example 4: To meet current lighting demand trends, the light guide component 2 is optimized based on Example 1, as follows: The lampshade 1 has multiple grooves on its outer side. These grooves are distributed circumferentially, in a linear array, or randomly on the outer side of the lampshade 1. The size of the grooves varies with the shape or remains constant. In this embodiment, the grooves are arranged in a linear array and their size varies with the shape. The grooves are fitted into the light guide components 2 one by one, and the size and shape of the corresponding light guide components 2 also vary with the shape, forming a multi-light path output structure. The light guide components 2 correspond to independent optical components 6 and light source modules, realizing zoned light control and personalized lighting design. The multi-path design of the light guide components 2 allows light to be independently exported at different angles, effectively avoiding cross-beaming and glare, and improving the clarity and layering of the lighting.

[0043] in: One connection method of the fixing bracket 22 is that the end of the fixing bracket 22 near the LED light source has a protrusion, and the outer side of the middle part has a groove. The protrusion and the groove cooperate with each other to achieve a snap-fit ​​connection.

[0044] The second connection method for the fixing bracket 22 is to glue or weld the end of the fixing bracket 22 closest to the LED light source to the middle part.

[0045] Example 5: To enhance the three-dimensional effect of the lamps, the decorative strip 3 is optimized based on Example 1: The decorative layer and decorative strip 3 are integrated into a single structure through a mold, wherein the decorative layer has raised patterns or raised stripes; thus, while achieving personalized appearance requirements, the visual three-dimensionality is enhanced.

[0046] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
