Description

Technical field:

[0001] The utility model relates to the technical field of automobile lamps, in particular to an extremely thin light-blocking structure between multifunctional thick walls. Background technology:

[0002] With the continuous advancement of automotive technology, multi-function headlights have become an integral part of modern vehicle design. They not only improve driving safety but also enhance the vehicle's visual aesthetics and practicality. Multi-function headlights integrate multiple lighting functions into a single module. Common functions include high beam, low beam, turn signals, brake lights, and daytime running lights. This design is designed to meet the needs of diverse driving scenarios while reducing the vehicle's overall weight and complexity. Since multiple lighting functions are integrated into a single module, avoiding interference between different functions is crucial. If light from different light sources bleeds into each other, it not only affects the lighting effect but can also cause visual confusion for the driver. Therefore, to enhance driving safety, it is crucial to ensure that each light source functions independently and clearly.

[0003] Traditional lamps with thick-walled optics currently utilize decorative rings to shield each functional area from light leakage and meet regulatory requirements. However, due to the thickness of the injection molded parts and the draft angle, the functional areas are often separated by large gaps. As automotive aesthetics become increasingly demanding, the spacing between functional areas is increasingly desired to be minimized, resulting in a more aesthetically pleasing and compact lamp structure.

[0004] For example, the Chinese patent application publication number CN 118548452 A discloses an integral luminous automobile lamp with multiple luminous functional bodies. In the solution disclosed in the patent, a partition assembly 4 is provided between the first thick-walled body 22 of the automobile lamp and the inner second thick-walled body 32 of the automobile lamp to block the propagation of light, thereby reducing the cross-lighting between the inner first thick-walled body 22 and the inner second thick-walled body 32 of the automobile lamp. In order to ensure the installation of the partition assembly 4, an inner segment spacer 5 is provided between the inner first thick-walled body 22 and the inner second thick-walled body 32 of the automobile lamp. This results in large intervals between the functional areas, making the lamp structure not compact and affecting the appearance of the lamp.

[0023] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0024] See Figures 1 to 5 The figure shows an extremely thin light-blocking structure between multifunctional thick-walled lamps, comprising a housing 1, at least two sets of thick-walled main bodies disposed within the housing 1 and corresponding to different functional lights, a light distribution mirror 2 mounted on the housing 1, and a decorative ring 3 disposed between the housing 1 and the light distribution mirror 2. A metal sheet 4 is disposed between the thick-walled main bodies and is mounted on one or both ends of the thick-walled main body by means of a clip; a first light-through hole 31 corresponding to the thick-walled main body is provided on the decorative ring 3. By disposing the metal sheet 4 between the thick-walled main bodies to block mutual interference of light, light leakage between lights of different functions is prevented. By utilizing the strength, elasticity, and light-proof properties of the metal sheet 4, the thickness of the shielding structure between the multifunctional thick-walled main bodies can be made thinner and smaller, and the effect of preventing light leakage can be achieved while meeting the requirements of relevant laws and regulations. This shortens the distance between the various functional areas, making the structure more compact, and adopts a screw-free assembly method to improve assembly efficiency. Secondly, there is no need for a shielding structure in the middle of the decorative ring 3, which can simplify the structure and the mold. The metal sheet 4 can be of a color close to the thick-walled main body. In addition, the metal sheet 4 is extremely thin and almost integrated with the thick-walled main body. It is difficult to see the existence of the metal sheet 4 from the outside, and the appearance of the entire lamp is more beautiful.

[0025] The metal sheet 4 is formed by a single stamping operation and includes a spacer portion 41 that fits on the end face of the thick-walled body, a first card portion 42 bent and formed on one side of the spacer portion 41, and a second card portion 43 bent and formed on the other side of the spacer portion 41. The first card portion 42 and the second card portion 43 cooperate to elastically clamp to one end of the thick-walled body. The spacer portion 41 is inserted between the two thick-walled bodies, and the bent first card portion 42 and the second card portion 43 are elastically fastened to one of the thick-walled bodies, thereby fixing the relative position of the spacer portion 41 and the thick-walled body. The metal sheet 4 is strong and has a certain degree of elasticity, so that a gap of 0.2 mm is left between the metal sheet 4 and the thick-walled body, thereby preventing the undesirable phenomenon of grinding during vibration.

[0026] The thick-walled body is provided with a first locking notch 5A and a second locking notch 5B, respectively, for aligning and positioning with the first locking portion 42 and the second locking portion 43.

[0028] The first card portion 42 is vertically bent on one side of the spacer portion 41 , and the second card portion 43 is L-shaped and vertically bent on the other side of the spacer portion 41 . An arc-shaped card 44 is provided beside the first card portion 42 .

[0029] In this embodiment, the thickness of the metal sheet 4 is 0.2-0.5mm, and it is formed by one-time stamping, and has certain strength, elasticity, and opaque properties; the gap between the metal sheet 4 and the thick-walled main body is only 0.2mm, and the gap between the two functional thick walls is 0.6-1.0mm; the metal sheet 4 utilizes the metal rebound characteristics and is fixed to one end of the thick-walled main body through a clip structure; the metal sheet 4 is silver, and the metal sheet 4 has the effect of blocking light and preventing light leakage; there is no need for any shielding structure in the middle of the decorative ring 3.

[0030] A control circuit board 6 is also provided in the shell 1, on which at least three groups of independently controlled lamp beads 7 are provided, and a first thick-walled body 51, a second thick-walled body 52 and a third thick-walled body 53 corresponding to different groups of lamp beads 7 are installed in the shell 1, and two metal sheets 4 are provided and are respectively located between the first thick-walled body 51 and the second thick-walled body 52 and between the second thick-walled body 52 and the third thick-walled body 53.

[0031] The metal sheets 4 are clamped and installed on the first thick-walled body 51 and the third thick-walled body 53, and the two metal sheets 4 are respectively located on one end surface of the first thick-walled body 51 relative to the second thick-walled body 52 and one end surface of the third thick-walled body 53 relative to the second thick-walled body 52.

[0032] The shell 1 is also equipped with a cover plate 8 covering the first thick-walled body 51, the second thick-walled body 52 and the third thick-walled body 53. The cover plate 8 is provided with a second light-through hole 81 for one end of the first thick-walled body 51, the second thick-walled body 52 and the third thick-walled body 53 to extend out. One end of the first thick-walled body 51, the second thick-walled body 52 and the third thick-walled body 53 extends through the second light-through hole 81, and the other end is restricted by the cover plate 8 in the shell 1; the decorative ring 3 is covered on the cover plate 8 and is clamped to the shell 1, and the light distribution mirror 2 is covered and buckled and clamped on the decorative ring 3.

[0033] The first thick-walled body 51 , the second thick-walled body 52 and the third thick-walled body 53 are all light-guiding lenses, and the first thick-walled body 51 , the second thick-walled body 52 and the third thick-walled body 53 are pressed against one side of the control circuit board 6 and refract the light at 90°.

[0034] In summary, in the present invention, a metal sheet 4 formed by a single stamping process is fixed to one or both ends of a thick-walled main body of one function by means of a clamp, and then the whole is installed on the shell 1 together with other functional thick-walled main bodies, and covered with a decorative ring 3 to shield the internal structure. Since the thick-walled main bodies are shielded by the metal sheet 4, the strength, resilience and opacity of the metal sheet 4 are rationally utilized, so that the thickness of the shielding structure between the various functional thick-walled main bodies can be made thinner and smaller, and the effect of preventing light leakage can be achieved, while meeting regulatory requirements, thereby shortening the intervals between the various functional areas, making the structure more compact, and adopting a screw-free assembly method to improve assembly efficiency. The metal sheet 4 is strong enough, leaving a gap of 0.2mm with the thick wall, and there will be no adverse phenomenon of grinding during vibration. Moreover, there is no need for a shielding structure in the middle of the decorative ring 3, so the structure can be simplified and the mold can be simplified accordingly; the metal sheet 4 can be made in a color close to the thick wall, and the metal sheet 4 is extremely thin and almost integrated with the thick wall. It is difficult to see the presence of the metal sheet from the appearance, and the appearance of the entire lamp is more beautiful.
