Description

Technical Field

[0001] The utility model relates to the technical field of automobile lamps, in particular to a light-weight thick-walled automobile lamp structure. Background Art

[0002] In the field of automotive lighting, lamps with thick-walled parts are more and more widely used because of their beautiful appearance and good lighting uniformity. However, the basic wall thickness of thick-walled parts is generally 2-3 times that of ordinary parts, which leads to a multiple increase in their own weight, an increase in the number of assembled parts, and a more complex matching structure.

[0003] For example, the patent number CN213920834U "Automobile Light System and Vehicle" includes a reflector, a light panel, a thick-walled part, a light-distributing part, etc., with a large number of parts and complex assembly. A large assembly space is required in the X and Z directions of the vehicle body coordinate system, resulting in a large space size for the entire lamp and an increase in the deadweight of the entire lamp, which is not conducive to the lightness of the lamp installation. Another example is the patent number CN218895325U "Automobile Light and Vehicle", which includes a lampshade, a light-transmitting part, a light-distributing sheet, etc. The fastening structure of the light-distributing sheet and the light-transmitting part requires a large assembly space in the direction of the second light-transmitting part, that is, the Z direction of the vehicle body coordinate system, resulting in a large space size for the entire lamp; at the same time, the upper and lower raised parts of the light-transmitting part and the upper and lower edges of the light-distributing sheet bring additional structural components to the parts, which is not conducive to the lightweight design of the product. In short, the thick-walled vehicle lamp structure in the prior art is generally large in size, occupies a large space, has complex parts matching, and is heavy. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0029] like Figure 1-4 As shown, in this embodiment, a lightweight thick-walled vehicle lamp structure is provided, which is composed of components such as a circuit board assembly 1, a bracket 2, a decorative ring 3, a thick-walled component 4 and a reflective element 5. The bracket 2 is generally installed inside the vehicle lamp, the decorative ring 3 is arranged at the outer end of the bracket 2, the circuit board assembly 1, the thick-walled component 4 and the reflective element 5 are all arranged on the inner side of the bracket 2, the reflective element 5 is fixed on the bracket 2, and the circuit board assembly 1 is fixedly fitted to one end of the reflective element 5, which can be fixed by riveting, clamping, screw connection or other fixing methods.

[0030] Specifically, the thick-walled member 4 is composed of an integrally-injected first portion 41 and a second portion 42, the second portion 42 being a light-transmitting area, the first portion 41 being a non-light-transmitting area, a light-homogenizing rib 424 being formed on the second portion 42, and a first limiting hole 413 being provided at one end of the first portion 41. The reflective element 5 is specifically composed of an integrally-injected reflector 51 and an inner lampshade 52, a second limiting hole 513 being provided at one end of the reflector 51, and a limiting rib 522 being formed on the inner lampshade 52. At the same time, a second welding portion 512 is provided on the side of the reflector 51 close to the second portion 42, and a first welding portion 425 is provided on the second portion 42 of the thick-walled member 4. In this way, the reflector 51 and the second part 42 are ultrasonically welded together through the first welding part 425 and the second welding part 512, and the light-homogenizing rib 424 can block the influence of the welding area to ensure the uniformity of lighting; in addition, an opening 31 is opened in the middle of the decorative ring 3, and the second part 42 of the thick-walled member 4 extends through the opening 31 of the decorative ring 3, that is, the opening surface 32 is exposed in the figure; and the light-homogenizing rib 424 of the second part 42 is clamped in the second limiting hole 513 of the reflector 51, and the limiting rib 522 of the inner lampshade 52 is clamped in the first limiting hole 413 of the first part 41. In this way, the thick-walled member 4 and the reflective element 5 can be stably matched, and the mutual clamping and welding method is adopted, the structure is firm and stable, replacing the original screw locking structure, reducing the number of parts, and also reducing the internal matching space volume, so that the overall size is smaller and tends to be lightweight. In addition, the thick-walled part 4 is designed to be an integrated structure of a first part 41 and a second part 42, and the reflective element 5 is designed to be an integrated structure of a reflector 51 and an inner lamp cover 52. On the one hand, a compact structural connection is achieved by means of staggered snap-fitting, thereby fully saving the internal space of the car lamp. On the other hand, the first part 41, as an opaque area, can block light, thereby reducing additional parts such as light-blocking brackets, thereby reducing the space volume and reducing the overall weight.

[0031] Specifically, a plurality of LEDs 11 are arranged on the surface of one side of the circuit board assembly 1 close to the reflective element 5 in this embodiment; the reflector 51 has a reflective surface 511 on the side close to the LED 11, and the reflective surface 511 can be a high-brightness surface or a high-brightness surface with aluminum plating; the two sides of the inner lampshade 52 are divided into a first light-entering surface 521 and a first light-emitting surface 523, the inner end of the second part 42 is a second light-entering surface 426, and the outer end of the second part 42 has a second light-emitting surface 422. With such a configuration, when the light is emitted during operation, the light emitted by the LED 11 can be directed toward the reflective surface 511, and after being reflected by the reflective surface 511, it passes through the first light-entering surface 521, the first light-emitting surface 523, and the second light-entering surface 426 in sequence, and finally emits from the second light-emitting surface 422.

[0032] More specifically, the reflector 51 in this embodiment also has a third base surface 514 and a fourth base surface 515 that are offset on the side close to the LED 11. The third base surface 514 and the fourth base surface 515 are both parallel to the circuit board assembly 1. The inner lampshade 52 is formed on the fourth base surface 515. The third base surface 514 is adjacent to the reflective surface 511 and the angle between the two is greater than 90 degrees, thereby ensuring the optical correspondence between the LED 11 and the reflective surface 511. The side wall of the second part 42 of the thick-walled member 4 close to the LED 11 is the first base surface 421 and the side wall away from the LED 11 is the second base surface 423. The light-homogenizing ribs 424 are formed on the second base surface 423, and the first part 41 is formed on the first base surface 421. Furthermore, in order to maximize the use of space to form a fit, the vertical distance from the fourth base surface 515 to LED11 is greater than the vertical distance from the third base surface 514 to LED11, and the vertical distance from the third base surface 514 to LED11 is greater than the vertical distance from the second base surface 423 to LED11.

[0033] In order to ensure the matching stability of the thick-walled member 4, the first portion 41 of the thick-walled member 4 in this embodiment has a first step 411 and a second step 412 at the end close to the decorative ring 3, and the inner side of the decorative ring 3 also has a corresponding step structure and is position-limited and engaged with the first step 411 and the second step 412. In this way, the thick-walled member 4 can be well limited and stable, and the light-shielding effect of the first portion 41 on the interior can be enhanced to ensure uniform light output.

[0034] Through the above design, this embodiment achieves optical lighting uniformity and consistency through the overall layout design of the circuit board assembly, reflector, inner lampshade, and the first and second parts of the thick-walled part, using the smallest spatial structure, and conforms to the lightweight design concept while optimizing optical performance.
