[0039] As a crucial component of automotive exterior design, headlights are increasingly trending towards continuous or slender designs. On one hand, continuous technological advancements in headlights, such as the application of new light sources like LEDs and OLEDs, enable more complex and varied lighting effects while maintaining high efficiency and low energy consumption. On the other hand, this reflects consumers' pursuit of personalized and refined vehicle design; continuous or slender headlight designs blend better with streamlined body contours, giving vehicles a more dynamic and stylish visual effect. Furthermore, this design also helps enhance the overall recognizability of the vehicle, making it more eye-catching at night or in complex lighting environments, thus meeting modern consumers' high standards for automotive aesthetics.
[0040] However, in actual use, the applicant found that the continuous or slender taillight design also faces certain shortcomings. Taking taillights as an example, when this design is adopted, the taillights are usually composed of end lights located at the corners of the vehicle body and a central light located on the trunk lid to achieve a continuous lighting effect. However, during the design and installation process, due to limitations in spatial layout and manufacturing processes, the transition area between the end lights and the central light often becomes a technical challenge. In this area of the end lights, due to spatial angle limitations, the light guide of the end lights cannot extend smoothly to the inner wall of the end light housing. This limitation makes it difficult for the light emitted by the light guide of the end lights to be effectively conducted to the thick-walled components inside this area, making this area appear darker compared to other parts. The central light area requires the installation of components such as the light source, substrate, fasteners, and light guide brackets, resulting in a relatively crowded internal space. Furthermore, the light source placed in this area is prone to producing high-brightness spots. In this area, the light guide of the central light can only conduct a small amount of light to the thick-walled components of the central light, making this area of the central light relatively dark. These uneven lighting phenomena not only disrupt the overall lighting effect of the taillights, making it difficult for the end lights and the middle lights to form a harmonious unity visually, but also affect the vehicle's aesthetics and overall quality to a certain extent.
[0041] In view of this, the present invention proposes a vehicle lamp structure to solve the above-mentioned technical problems.
[0042] Please see Figure 1 In one embodiment of this utility model, the vehicle lamp structure 1000 includes an end lamp 1 and an intermediate lamp 2, wherein the end lamp 1 and the intermediate lamp 2 are arranged at intervals; the end lamp 1 includes a first lamp housing 11, a first lamp cover 12, a first light guide 13, and a diffuser hemisphere 14, the first lamp housing 11 and the first lamp cover 12 forming a first receiving cavity 15, and the first light guide 13 and the diffuser hemisphere 14 are both disposed in the first receiving cavity 15; the intermediate lamp 2 includes a second lamp housing 21 and a second lamp cover. The second light guide 22, the second lamp housing 21, and the second lamp shade 22 together form a second accommodating cavity 24, and the second light guide 23 is disposed in the second accommodating cavity 24; the diffuser hemisphere 14 is disposed at one end of the first light guide 13 near the middle lamp 2; the second light guide 23 includes a bent section 231 disposed near the end lamp 1, and a diffusion pattern portion 2311 is disposed on the side of the bent section 231 near the second lamp shade 22, and the diffusion pattern portion 2311 is used to diffuse the light in the second light guide 23.
[0043] In the headlight structure 1000, the dark area (dimmer region) on the side of the end lamp 1 near the middle lamp 2 is the first transition zone A, and the dark area on the side of the middle lamp 2 near the end lamp 1 is the second transition zone B. A first lampshade 12 covers the first lamp housing 11 to form a first receiving cavity 15, and a second lampshade 22 covers the second lamp housing 21 to form a second receiving cavity 24. Both the first lampshade 12 and the second lampshade 22 are transparent or semi-transparent light-transmitting components. To conform to a through-type or elongated headlight design, the first receiving cavity 15 extends along the corner of the vehicle's rear and side profile, and the second receiving cavity 24 extends along the rear of the vehicle and in a direction parallel to the ground. Overall, both the first receiving cavity 15 and the second receiving cavity 24 are elongated cavities. In this embodiment, the first light guide 13 is disposed in the first accommodating cavity 15 and extends along the extending direction of the first accommodating cavity 15; the second light guide 23 is disposed in the second accommodating cavity 24 and extends along the extending direction of the second accommodating cavity 24. A diffuser hemisphere 14 is disposed at the end of the first light guide 13 near the intermediate lamp 2. Specifically, the diffuser hemisphere 14 is disposed at the end of the first light guide 13 located in the first transition zone A. The diffuser hemisphere 14 has a hemispherical structure, with its convex surface facing the intermediate lamp 2. Compared to when the end of the first light guide 13 near the intermediate lamp 2 is flat, the diffuser hemisphere 14 increases the diffuser area in the first transition zone A, allowing the diffuser hemisphere 14 to diffuse the light from the first light guide 13 into the first transition zone A, thus preventing insufficient light reception in the first transition zone A. The dark area near the end lamp 1 of the middle lamp 2 is the second transition zone B. A bent section 231 is disposed in the second transition zone B, and the bent section 231 is generally arc-shaped. In this embodiment, a diffusion pattern portion 2311 is provided on the side of the bent section 231 near the second lampshade 22. When the light transmitted in the second light guide 23 passes through the diffusion pattern portion 2311, some of the light diffuses into the second transition zone B. The diffusion pattern portion 2311 can adjust the direction of light emission, so that the components in the second transition zone B near the second lampshade 22 can uniformly receive the light scattered by the diffusion pattern portion 2311. In this embodiment, the diffusion pattern portion 2311 is disposed at the edge of the bent section 231 in the second transition zone B and extends a certain length within the second transition zone B, aiming to ensure that the light scattered by the diffusion pattern portion 2311 can cover the components in the second transition zone B near the second lampshade 22. The diffused pattern portion 2311 includes one of the uneven wave-shaped pattern, fish-scale pattern, and polygonal pattern provided on the surface of the bent section 231. The diffused pattern portion 2311 may also be dot-shaped protrusions provided at intervals on the surface of the bent section 231.
[0044] The technical solution of this embodiment adds a diffuser hemisphere 14 to the end of the first light guide 13 near the middle lamp 2, and sets a bend in the second light guide 23 near the end lamp 1, with a diffusion pattern 2311 on the side of the bend near the second lamp cover 22. In the area of the end lamp 1 near the middle lamp 2, the light in the first light guide 13 can be uniformly transmitted to this area through the diffuser hemisphere 14, thereby eliminating dark areas with low brightness. At the same time, in the area of the middle lamp 2 near the end lamp 1, the light in the second light guide 23 can be uniformly diffused to this area through the diffusion pattern 2311, thereby eliminating dark areas in this area. Through the above settings, the uniformity of light emission from the end lamp 1 and the middle lamp 2 can be improved, thereby improving the continuity and uniformity of light emission from the vehicle lamp structure 1000.
[0045] Further, in one embodiment of this utility model, the first light guide 13 includes a continuously arranged low beam segment 131 and a high beam segment 132. The end lamp 1 also includes a first light source 16 and a first thick-walled member 18 disposed in the first accommodating cavity 15. The first light source 16 is disposed at the end of the low beam segment 131 away from the intermediate lamp 2. The other end of the low beam segment 131 is connected to one end of the high beam segment 132. The end of the high beam segment 132 near the intermediate lamp 2 is connected to the diffuser hemisphere 14. The first thick-walled member 18 is disposed between the first light guide 13 and the first lamp cover 12, and the first thick-walled member 18 is correspondingly disposed with the low beam segment 131 and the high beam segment 132. A turning portion 1311 is provided at the end of the low beam segment 131 near the high beam segment 132. The turning portion 1311 is used to adapt to the angle between the side of the vehicle and the front of the vehicle, or to adapt to the angle between the side of the vehicle and the rear of the vehicle. Please refer to [link to relevant documentation]. Figure 2 and Figure 3Compared to the high beam segment 132, the low beam segment 131 is positioned further away from the center lamp 2. The first light source 16 is used to input light into the low beam segment 131, and the light in the low beam segment 131 can be transmitted to the high beam segment 132. The low beam segment 131 and the high beam segment 132 are integrally formed to improve the light transmission efficiency between them. The high beam segment 132 and the low beam segment 131 are connected by a bend 1311. Taking the taillight as an example, by setting the bend 1311, the low beam segment 131 can adapt to the corner between the side and rear of the vehicle body. Depending on the vehicle model, the curvature of the bend at the corner is different, and the bend 1311 needs to be adjusted according to the curvature of the bend at the corner. The first thick-walled member 18 is used to receive the light emitted from the low beam segment 131 and the high beam segment 132 and direct the light towards the first lampshade 12. Multiple quadrilateral patterns are provided on the side of the first thick-walled member 18 facing the first light guide 13 to adjust the angle of the light in the first thick-walled member 18 so that the light is directed towards the first lampshade 12. Multiple fish-scale patterns (or corn kernel patterns) are also provided on the side of the first thick-walled member 18 facing the first lampshade 12. These fish-scale patterns are used to evenly diffuse the light in the first thick-walled member 18 and direct it towards the first lampshade 12. Furthermore, the first light source 16 includes either an LED light or a laser light. In this embodiment, to reduce costs, the first light source 16 uses an LED light.
[0046] Furthermore, in one embodiment of this utility model, please refer to... Figure 2 and Figure 3 The first light guide 13 also includes a supplementary light section 133, which extends from the end of the high beam section 132 near the low beam section 131 towards the direction away from the intermediate lamp 2. The end lamp 1 also includes a supplementary light source 17, which is located at the end of the supplementary light section 133 away from the intermediate lamp 2. The supplementary light section 133 is integrally formed with the low beam section 131 and the high beam section 132. The supplementary light section 133 is used to transmit light to the high beam section 132. There is no bend between the supplementary light section 133 and the high beam section 132, so that the light from the supplementary light source 17 entering the supplementary light section 133 can smoothly enter the high beam section 132. This avoids the situation where only a small amount of light from the low beam section 131 is transmitted to the high beam section 132 due to the presence of the bend 1311, resulting in a dim light output from the high beam section 132. By setting up the supplementary light section 133, the uniformity of light emission from the near beam section 131 and the high beam section 132 can be improved, thereby ensuring that the amount of light entering the corresponding parts of the first thick-walled member 18 and the near beam section 131 and the high beam section 132 is approximately the same, and thus making the light emission effect of each area of the first thick-walled member 18 basically the same. It should be noted that when designing the supplementary light section 133, the amount of light transmitted to the high beam section 132 can be adjusted by changing the length of the supplementary light section 133.
[0047] In one embodiment of this utility model, the high beam segment 132 includes a transition portion 1321 and a light guide portion 1322. A diffuser hemisphere 14 is mounted on one end of the transition portion 1321 near the intermediate lamp 2, and the other end of the transition portion 1321 is connected to the light guide portion 1322. Both the light guide portion 1322 and the low beam segment 131 are provided with end light guide teeth 134, which are located on the side of the light guide portion 1322 and the low beam segment 131 away from the first lamp cover 12. Please refer to [link / reference]. Figure 1 Considering that the transition section 1321 is equipped with a diffuser hemisphere 14, in order to reduce the processing difficulty, end light guide teeth 134 are provided in the light guide section 1322 and the near light section 131. In this embodiment, the end light guide teeth 134 are also provided in the supplementary light section 133 to prevent the light in the supplementary light section 133 from scattering in all directions and affecting the light emission effect of the part of the first thick-walled member 18 corresponding to the near light section 131. The end light guide teeth 134 are provided on the side of the first light guide 13 away from the first thick-walled member 18, and are used to adjust the direction of the light in the first light guide 13 and reflect the light in the first light guide 13 to the first thick-walled member 18.
[0048] Please see Figures 1 to 3 In one embodiment of this utility model, the intermediate lamp 2 further includes a second light source 25 and a second thick-walled member 26 disposed in the second accommodating cavity 24. The second light source 25 is disposed at one end of the second light guide 23 near the end lamp 1, and the second thick-walled member 26 is disposed between the second lamp housing 21 and the second light guide 23. The second light guide 23 and the second thick-walled member 26 extend along the extending direction of the second accommodating cavity 24. The second light guide 23 and the second thick-walled member 26 are correspondingly disposed, and the second light source 25 is used to input light into the second light guide 23. The light propagates along the second light guide 23 and is conducted by the second light guide 23 to the second thick-walled member 26. The second thick-walled member 26 has multiple quadrilateral patterns on the side facing the second light guide 23 to adjust the angle of the light rays in the second thick-walled member 26 so that the light rays are emitted towards the second lampshade 22. The second thick-walled member 26 also has multiple fish-scale patterns on the side facing the second lampshade 22 to evenly diffuse the light rays in the second thick-walled member 26 and emit them towards the second lampshade 22. By setting the second thick-walled member 26, the luminous effect of the intermediate lamp 2 is made more continuous and uniform. It should also be noted that the second light source 25 includes either an LED lamp or a laser lamp. In this embodiment, to reduce production costs, the second light source 25 uses an LED lamp.
[0049] Further, please refer to Figure 1In one embodiment of this utility model, a protrusion 211 is provided on the side of the second lamp housing 21 near the middle lamp 2, and the protrusion 211 protrudes in a direction away from the second lamp cover 22; the second light source 25 includes a second lamp bead 251 and a second substrate 252, the second lamp bead 251 is mounted on the second substrate 252, the second substrate 252 is mounted on the side of the protrusion 211 facing the second lamp cover 22, and the second lamp bead 251 is disposed towards the second lamp cover 22; one end of the bent section 231 is disposed away from the second thick-walled member 26 and towards the second lamp bead 251, and the other end of the bent section 231 is disposed away from the end lamp 1 and close to the second thick-walled member 26; the second light guide 23 also includes an extension section 232, the end of the extension section 232 close to the end lamp 1 is connected to the end of the bent section 231 away from the end lamp 1, and the extension section 232 extends in a direction away from the end lamp 1. This arrangement allows for greater space on the side of the intermediate lamp 2 closer to the end lamp 1. The second lamp bead 251, along with the second substrate 252, is positioned on the side of the second accommodating cavity 24 away from the second lamp cover 22. This arrangement, combined with the bend 231 of the second light guide 23, helps to conceal the second lamp bead 251, preventing pedestrians or other drivers from noticing the bright spot formed by it. Simultaneously, the bend 231 is arc-shaped. Due to the effect of the second lamp bead 251, bright spots might form in the bend 231. However, by providing a diffusion pattern 2311 within the bend 231, this formation of bright spots is avoided, thereby improving the uniformity and continuity of the overall vehicle lamp structure 1000's light emission. Furthermore, the extension 232 extends along the second accommodating cavity 24 without corners or bends, ensuring a straight propagation path for light within the extension 232. This reduces light scattering and reflection losses, improving light transmission efficiency.
[0050] In one embodiment of this utility model, the extension segment 232 is provided with an extension light guide tooth 2321. The extension light guide tooth 2321 is located on the side of the extension segment 232 away from the second thick-walled member 26. The extension light guide tooth 2321 is used to reflect the light in the extension segment 232 to the second thick-walled member 26. When the light is transmitted inside the second light guide 23, the extension light guide tooth 2321 can guide the reflection direction of the light, so that the light can be uniformly reflected to the second thick-walled member 26, avoiding light scattering and reducing light loss during transmission. The extension light guide tooth 2321 is integrally formed with the extension segment 232.
[0051] In one embodiment of this utility model, the astigmatic hemisphere 14 and the first light guide 13 are integrally formed. The integral forming design makes the light transmission more direct, and the light transmission will not be affected by gaps in the middle, thereby ensuring that the astigmatic hemisphere 14 can receive sufficient light.
[0052] In one embodiment of this utility model, the vehicle lamp structure 1000 further includes a first bracket 19 and a second bracket 27. The first bracket 19 is used to mount a first light guide 13 and is mounted on a first lamp housing 11; the second bracket 27 is used to mount a second light guide 23 and is mounted on a second lamp housing 21. Please refer to [link / reference]. Figure 1 Since the first light guide 13 and the second light guide 23 have relatively long extension lengths, a first bracket 19 and a second bracket 27 are provided in this embodiment for mounting the first light guide 13 and the second light guide 23, respectively. The first bracket 19 and the second bracket 27 are integrated on the corresponding lamp housings, which can fix the first light guide 13 and the second light guide 23 and prevent the first light guide 13 and the second light guide 23 from being misaligned due to vehicle vibration, thus affecting the luminous effect of the vehicle lamp structure 1000.
