[0002] With the rapid development of automotive lighting technology and increasingly higher customer demands for the appearance of headlights, the need for slender, continuous light emission from headlights is becoming increasingly prominent. However, the design of current front position lights faces a significant technical dilemma: to ensure uniform and reliable assembly gaps between the lamp body and surrounding components, a segmented structure must be adopted. However, this design sacrifices the visual continuity of the light and cannot achieve a truly continuous light emission effect. Utility Model Content

[0003] The main purpose of this utility model is to propose an integrated through-type headlight structure, which aims to solve the problem that the front position lights, due to their segmented design, lack light continuity and cannot achieve a continuous through-type light emission effect while ensuring uniform gaps with surrounding components.

[0014] In this embodiment of the utility model, the integrated through-type headlight structure includes an integrated headlight assembly, a first adjustment mechanism, a second adjustment mechanism, and a third adjustment mechanism. The integrated headlight assembly extends continuously along the lateral direction of the vehicle, forming a visually seamless through-type light source, and is provided with headlight mounting feet for assembly and connection with the vehicle body. The first, second, and third adjustment mechanisms each include an adjusting component and a connecting component. The connecting component is connected to a nut on the vehicle body mounting sheet metal, and the adjusting component is movably mounted on the corresponding headlight mounting foot. Specifically, the first adjustment mechanism is used to adjust the position of the integrated headlight assembly in the vertical direction, the second adjustment mechanism is used to adjust its position in the lateral direction (left-right direction) of the vehicle, and the third adjustment mechanism is used to adjust its position in the longitudinal direction. The three adjustment directions are perpendicular to each other, forming an orthogonal three-dimensional adjustment system. This structure employs three independent adjustment mechanisms, each corresponding to a single direction of relative displacement adjustment. This allows the integrated headlight assembly to be independently fine-tuned in three directions—up / down, left / right, and front / back—during assembly. This effectively compensates for spatial deviations caused by body sheet metal tolerances, component deformation, or installation stress, preventing uneven gaps or interference between the headlight assembly and surrounding components such as bumpers and fenders. Because the integrated headlight assembly is a continuous structure extending laterally along the vehicle, the synergistic effect of the three-way adjustment mechanisms achieves high-precision assembly while maintaining the physical continuity and optical coherence of the headlight assembly. This solves the problem of traditional technologies that forced segmented designs due to the inability to perform multi-directional adjustments on long headlights, thus balancing luminous continuity and assembly reliability. Without adding additional split structures, this design achieves precise control of the headlight assembly's spatial posture through a three-way adjustment mechanism, improving the overall vehicle appearance quality and manufacturing tolerance. Simultaneously, it reduces the number of headlight components, simplifies the assembly process, and lowers production and maintenance costs, demonstrating excellent engineering practicality and market application value. This utility model embodiment uses three mutually perpendicular adjustment mechanisms to achieve three-dimensional fine-tuning of the integrated headlight assembly, effectively compensating for assembly deviations and avoiding uneven gaps or interference with surrounding parts. At the same time, it maintains the continuous overall structure of the integrated headlight assembly along the vehicle's transverse direction, ensuring the continuity of optical effects and the visual extension of the front face when illuminated. This solves the technical problem that traditional segmented designs cannot balance assembly reliability and light emission continuity. Attached Figure Description

[0022] With the rapid development of automotive lighting technology and increasingly higher customer demands for the appearance of headlights, the need for slender, continuous light emission from headlights is becoming increasingly prominent. However, the design of current front position lights faces a significant technical dilemma: to ensure uniform and reliable assembly gaps between the lamp body and surrounding components, a segmented structure must be adopted. However, this design sacrifices the visual continuity of the light and cannot achieve a truly continuous light emission effect.

[0023] After careful examination, the applicant discovered that due to the relatively long overall size of the front position lights, a one-piece structure would easily lead to uneven gaps or even interference between the light body and surrounding components such as the bumper and fenders in localized areas during vehicle assembly due to factors such as sheet metal tolerances, component deformation, or installation stress. To address this assembly reliability issue, the front position lights are generally divided into three independent modules: left, center, and right, each fixed to the body sheet metal by its own mounting bracket. Each segment of the light body, due to its shorter size and better rigidity, can be independently adjusted or adapted to its installation position, effectively ensuring the uniformity of the gaps between each segment and surrounding components. Because of this, it is impossible to combine the left, center, and right light segments into one unit, meaning the continuity of the front position lights cannot be guaranteed. There are physical breaks and optical interruptions between the three segments, creating discontinuous light bands when illuminated, which disrupts the overall visual extension and technological feel of the front fascia. The fundamental reason is that traditional technology lacks an installation structure that can achieve multi-directional fine adjustment on a long, integrated lamp body. It cannot ensure the overall continuity of the lamp body while dynamically compensating for spatial errors during the assembly process. Therefore, it can only achieve assembly feasibility through a divide-and-conquer segmented design, which ultimately makes it impossible to simultaneously achieve the two major goals of uniform gaps and continuous light emission.

[0024] The main purpose of this utility model is to propose an integrated through-type headlight structure to solve the problem that the front position lights, due to their segmented design, lack light continuity and cannot achieve a continuous through-type light emission effect while ensuring uniform gaps with surrounding components.

[0025] Please see Figure 1 , Figure 2 and Figure 4In one embodiment of this utility model, the integrated through-type headlight structure 100 includes an integrated headlight assembly 1 and an adjustment mechanism. The integrated headlight assembly 1 extends continuously along the lateral direction of the vehicle to form a continuously emitting through-type light source. A headlight mounting foot is provided on the integrated headlight assembly 1. The adjustment mechanism includes an adjustment member 21 and a connecting member 22 connected to each other. The connecting member 22 is used to connect with a nut 210 on the vehicle body mounting sheet metal 200. The adjustment member 21 is movably mounted on the headlight mounting foot. There are multiple adjustment mechanisms. The number of nuts 210 is the same as the number of adjustment mechanisms and they are arranged in a one-to-one correspondence. The multiple adjustment mechanisms are divided into a first adjustment mechanism 2, a second adjustment mechanism 3, and a third adjustment mechanism 4. There are multiple headlight mounting feet. The multiple headlight mounting feet are divided into a first headlight mounting foot 111, a second headlight mounting foot 112, and a third headlight mounting foot 113. The number of first adjustment mechanisms 2 is the same as the number of first headlight mounting feet 111 and they are arranged in a one-to-one correspondence. The number of adjustment mechanisms 3 and the number of second headlight mounting feet 112 are the same and they are arranged in a one-to-one correspondence. The number of adjustment mechanisms 4 and the number of third headlight mounting feet 113 are the same and they are arranged in a one-to-one correspondence. The adjustment component 21 of the first adjustment mechanism 2 can move relative to the first headlight mounting foot 111 in a first direction, so that the first adjustment mechanism 2 can adjust the distance from the first headlight mounting foot 111 to the body mounting sheet metal 200 in the first direction. The adjustment component 21 of the second adjustment mechanism 3 can move relative to the second headlight mounting foot 112 in a second direction, so that the second adjustment mechanism 3 can adjust the distance from the second headlight mounting foot 112 to the body mounting sheet metal 200 in the second direction. The adjustment component 21 of the third adjustment mechanism 4 can move relative to the third headlight mounting foot 113 in a third direction, so that the third adjustment mechanism 4 can adjust the distance from the third headlight mounting foot 113 to the body mounting sheet metal 200 in the third direction. The first direction, the second direction and the third direction are perpendicular to each other.

[0026] In this embodiment of the utility model, the first direction is the vertical direction, the second direction is the horizontal direction (also the vehicle's lateral direction), and the third direction is the front-rear direction. The integrated through-type headlight structure 100 includes an integrated headlight assembly 1, a first adjustment mechanism 2, a second adjustment mechanism 3, and a third adjustment mechanism 4. The integrated headlight assembly 1 extends continuously along the vehicle's lateral direction, forming a visually seamless through-type light source, and is provided with headlight mounting feet for assembly and connection with the vehicle body. The first adjustment mechanism 2, the second adjustment mechanism 3, and the third adjustment mechanism 4 each include an adjustment component 21 and a connecting component 22. The connecting component 22 is connected to a nut 210 on the vehicle body mounting sheet metal 200, and the adjustment component 21 is movably mounted on the corresponding headlight mounting foot. Among them, the first adjustment mechanism 2 is used to adjust the position of the integrated headlight assembly 1 in the vertical direction, the second adjustment mechanism 3 is used to adjust its position in the vehicle's lateral direction (left-right direction), and the third adjustment mechanism 4 is used to adjust its position in the front-rear direction. The three adjustment directions are perpendicular to each other, forming an orthogonal three-dimensional adjustment system. This structure employs three independent adjustment mechanisms, each corresponding to a specific direction of relative displacement adjustment. This allows the integrated headlight assembly 1 to be independently fine-tuned in three directions—up / down, left / right, and front / back—during assembly. This effectively compensates for spatial deviations caused by body sheet metal tolerances, component deformation, or installation stress, preventing uneven gaps or interference between the headlight assembly and surrounding components such as the bumper and fenders. Since the integrated headlight assembly 1 is a continuous, transversely extending structure, the synergistic effect of the three-way adjustment mechanisms achieves high-precision assembly while maintaining the physical continuity and optical coherence of the headlight assembly. This solves the problem of traditional technologies that force segmented designs due to the inability to perform multi-directional adjustments on long headlights, thus balancing luminous continuity and assembly reliability. Without adding additional split structures, this design achieves precise control of the headlight assembly's spatial posture through a three-way adjustment mechanism, improving the overall vehicle appearance quality and manufacturing tolerance. Simultaneously, it reduces the number of headlight components, simplifies the assembly process, and lowers production and maintenance costs, demonstrating excellent engineering practicality and market application value.

[0027] The technical solution of this utility model adopts three mutually perpendicular adjustment mechanisms to achieve three-dimensional fine adjustment of the integrated headlight assembly 1, effectively compensating for assembly deviations and avoiding uneven gaps or interference with surrounding parts. At the same time, it maintains the continuous overall structure of the integrated headlight assembly 1 along the vehicle's transverse direction, ensuring the continuity of optical effects and the extension of the front face visually when illuminated. This solves the technical problem that traditional segmented designs cannot simultaneously achieve uniform gaps and continuous light emission.

[0028] Please see Figure 3In one embodiment, the connector 22 includes a stop portion 221 and a connecting portion 222 connected to each other. The adjusting member 21 is provided with a through hole 213 for the connecting portion 222 to pass through. The connecting portion 222 is rotatably connected to the wall of the through hole 213. The connecting portion 222 is connected to the nut 210. The outer wall of the adjusting member 21 is provided with a first threaded section 2111. The headlight mounting foot is provided with a threaded hole 1111 that is threadedly engaged with the first threaded section 2111. The two sides of the adjusting member 21 that are opposite to each other abut against the stop portion 221 and the body mounting sheet metal 200, respectively. Specifically, this structure forms a reference by connecting the connecting member 22 to the nut 210 on the body mounting sheet metal 200. The adjusting member 21 is rotatably fitted onto the connecting portion 222 and engages with the headlight mounting foot through the outer peripheral first threaded section 2111. When the adjusting component 21 is rotated, it moves axially under the action of the thread, pushing the lamp mounting foot to displace relative to the vehicle body, thereby achieving precise adjustment of the lamp body in the first direction. At the same time, the two ends of the adjusting component 21 abut against the stop part 221 and the body mounting sheet metal 200 respectively, forming a stable axial support, effectively transmitting the adjustment force and preventing loosening and falling off. This not only ensures the smoothness of the adjustment process and the accuracy of positioning, but also improves the overall rigidity and reliability of the connection structure.

[0029] According to one embodiment of the present invention, the adjusting member 21 and the vehicle light mounting foot can be moved relative to each other by means of sliding cooperation between the slider and the guide hole or guide groove.

[0030] Please see Figure 3In one embodiment, the adjusting member 21 includes an adjusting part 211 and a mounting part 212, which are connected to form a through hole 213. The mounting part 212 is located on the side of the adjusting part 211 near the stop part 221, and the diameter of the mounting part 212 is larger than the diameter of the adjusting part 211. The outer wall of the adjusting part 211 is provided with a first threaded section 2111. The side of the adjusting part 211 away from the mounting part 212 is used to abut against the vehicle body mounting sheet metal 200, and the side of the mounting part 212 away from the adjusting part 211 is used to abut against the stop part 221. The first threaded section 2111 of the first adjusting mechanism 2 extends along a first direction so that the first adjusting mechanism 2 can adjust the distance from the first headlight mounting foot 111 to the vehicle body mounting sheet metal 200 along the first direction. The first threaded section 2111 of the second adjusting mechanism 3 extends along a first direction to adjust the distance from the first headlight mounting foot 111 to the vehicle body mounting sheet metal 200. The threaded section 2111 extends along the second direction so that the second adjustment mechanism 3 can adjust the distance from the second headlight mounting foot 112 to the body mounting sheet metal 200 along the second direction; the first threaded section 2111 of the third adjustment mechanism 4 extends along the third direction so that the third adjustment mechanism 4 can adjust the distance from the third headlight mounting foot 113 to the body mounting sheet metal 200 along the third direction; specifically, the connecting part 222 of the connector 22 passes through the through hole 213 and is connected to the nut 210 on the body mounting sheet metal 200 to achieve a rotational fit; the mounting part 212 is located on the side of the adjustment part 211 near the stop part 221, and its diameter is larger than that of the adjustment part 211, forming a stepped structure; the outer wall of the adjustment part 211 is provided with a first threaded section 2111 for engaging with the threaded hole 1111 on the headlight mounting foot. The side of the adjusting part 211 away from the mounting part 212 is used to abut against the body mounting sheet metal 200, and the side of the mounting part 212 away from the adjusting part 211 is used to abut against the stop part 221, forming a stable force-bearing state with support at both ends during the adjustment process. Among them, the first threaded section 2111 of the first adjusting mechanism 2 extends in the vertical direction (first direction), and the first headlight mounting foot 111 can be driven to move in the vertical direction by rotating the adjusting member 21 to adjust the height position of the headlight body; the first threaded section 2111 of the second adjusting mechanism 3 extends in the horizontal direction (second direction, i.e., the vehicle lateral direction), and drives the second headlight mounting foot 112 to make slight adjustments in the lateral direction during adjustment to ensure that the headlight body is aligned with the surrounding parts laterally; the first threaded section 2111 of the third adjusting mechanism 4 extends in the front-rear direction (third direction), and changes the front-rear distance between the third headlight mounting foot 113 and the body during adjustment to optimize the surface difference between the headlight body and the bumper. This structure, through the unified stepped threaded adjustment component 21 design, combined with the thread extension layout in different directions, achieves precise, stable, and repeatable fine-tuning of the integrated headlight assembly 1 in three-dimensional space. It effectively compensates for the fit deviation caused by manufacturing tolerances or assembly deformation, avoids uneven local gaps or interference, maintains the overall continuity of the lamp body, takes into account assembly reliability and appearance quality, and has strong structural versatility, which helps to reduce the types of parts and production costs.In this embodiment, the first adjustment mechanism 2, the second adjustment mechanism 3, and the third adjustment mechanism 4 are consistent in composition, connection relationship, and adjustment principle. This reusable design not only simplifies the types of parts and reduces mold development costs and production management complexity, but also improves the consistency of assembly processes, facilitating assembly line operations and maintenance / replacement. Simultaneously, the coordinated application of the same structure in three orthogonal directions ensures uniform adjustment operation methods and consistent force patterns in all directions, enhancing the reliability and controllability of the overall adjustment system. This facilitates precise alignment of the integrated headlight assembly 1 in three-dimensional space, effectively compensating for assembly errors and ensuring that the gap surface difference between the integrated headlight assembly 1 and surrounding components meets design requirements.

[0031] Please see Figure 3 In one embodiment, the adjusting member 21 further includes an adjusting shim 23, which is located between the stop portion 221 and the mounting portion 212. The two ends of the adjusting shim 23 respectively abut against the stop portion 221 and the mounting portion 212. Specifically, by providing the adjusting shim 23 between the stop portion 221 and the mounting portion 212, this structure effectively fills the assembly gap between them, compensates for contact surface deviations caused by manufacturing tolerances, processing deformation, or surface unevenness, and ensures that the contact surfaces between the stop portion 221 and the mounting portion 212 remain parallel. This ensures that the adjusting member 21 is subjected to uniform force during installation and adjustment, avoiding jamming, wear, or loosening caused by localized stress concentration or tilting. Simultaneously, the adjusting shim 23 maintains the axial positioning stability of the adjusting member 21, enabling synchronous and reliable abutment between its two ends (the adjusting portion 211 and the body sheet metal, and the mounting portion 212 and the stop portion 221), thereby ensuring precise adjustment and locking of the headlight mounting feet in the first direction. In addition, by selecting adjusting shims 23 of different thicknesses, fine adjustments can be made to the preload and initial position, improving assembly accuracy and consistency, and enhancing the overall rigidity and long-term reliability of the connection structure.

[0032] Please see Figure 3In one embodiment, the outer wall of the connecting part 222 is provided with a second threaded section 2221, which is threadedly engaged with the nut 210. Specifically, this structure, by providing the second threaded section 2221 on the outer wall of the connecting part 222, allows it to be directly screwed into and fixed in the nut 210 on the body mounting sheet metal 200, forming a stable and reliable mechanical connection. This connection method not only achieves axial locking between the connecting part 22 and the body mounting sheet metal 200, preventing loosening or detachment during assembly or use, but also provides a stable force reference for the adjustment action of the adjusting part 21. Since the adjusting part 21 is movably mounted on the headlight mounting foot and the position of the integrated headlight assembly 1 is adjusted by rotation, its adjustment force relies on the fixed anchor point between the connecting part 222 and the body mounting sheet metal 200 for reverse support. The threaded engagement between the second threaded section 2221 and the nut 210 can withstand the axial force and torsional load generated during the adjustment process, ensuring that the adjustment process is smooth and controllable. Meanwhile, this threaded connection structure boasts mature technology and convenient assembly, requiring no additional fasteners, simplifying the installation process and improving production efficiency. Furthermore, by controlling the engagement depth, it is possible to adjust the axial preload, further enhancing the reliability and consistency of the connection.

[0033] According to one embodiment of the present invention, the connecting part 222 and the body mounting sheet metal 200 are detachably connected by a snap-fit ​​method.

[0034] According to one embodiment of the present invention, the connecting part 222 and the body mounting sheet metal 200 are fixedly connected by welding and riveting.

[0035] Please see Figures 1 to 3In one embodiment, the first lamp mounting foot 111 and the second lamp mounting foot 112 are connected; and / or, the first lamp mounting foot 111 and the third lamp mounting foot 113 are connected; and / or, the second lamp mounting foot 112 and the third lamp mounting foot 113 are connected. Specifically, this structure forms an integrated, one-piece mounting base by connecting lamp mounting feet with different functions. When two or more lamp mounting feet are connected to each other, they can jointly bear and transmit the adjustment force from each adjustment mechanism, improving the overall structural rigidity and assembly stability. At the same time, the connected lamp mounting feet can respond collaboratively to fine-tuning movements in the up-down, lateral, and front-back directions, avoiding local deformation or stress concentration of the lamp body caused by independent force on each mounting point, ensuring that the integrated headlight assembly 1 maintains a stable overall posture during three-dimensional adjustment. In addition, the connection design of multiple lamp mounting feet helps to simplify the internal structural layout of the lamp, reduce the number of mounting points, improve space utilization, and enhance the support capacity for long-length through-type lamp bodies, especially suitable for lamp structures that extend long along the lateral direction of the vehicle. This connection method can be flexibly selected according to the actual structural strength and assembly requirements, achieving both fully integrated and partial connections, demonstrating good adaptability and engineering application value. In this embodiment, the first headlight mounting foot 111 is provided separately, while the second headlight mounting foot 112 and the third headlight mounting foot 113 are connected.

[0036] Please see Figure 1In one embodiment, the number of first adjustment mechanisms 2 is at least two, and the at least two first adjustment mechanisms 2 are spaced apart along the second direction; and / or, the number of second adjustment mechanisms 3 is at least two, and the at least two second adjustment mechanisms 3 are spaced apart along the second direction; and / or, the number of third adjustment mechanisms 4 is at least two, and the at least two third adjustment mechanisms 4 are spaced apart along the second direction. Specifically, this design forms a multi-point support and adjustment layout by setting multiple adjustment mechanisms of the same type in the second direction (the vehicle's transverse direction, i.e., the continuous extension direction of the integrated headlight assembly 1), effectively improving the uniformity of force and structural stability of the integrated headlight assembly 1 in the corresponding adjustment direction. When multiple adjustment mechanisms of a certain type are set, local stress concentration or tilting deformation of the lamp body caused by single-point adjustment can be avoided, ensuring that the lamp body moves smoothly during the adjustment process and improving assembly accuracy and reliability. At the same time, the distribution of multiple adjustment mechanisms along the length direction of the lamp body can better compensate for the non-uniform tolerance or deformation of the body sheet metal over long distances, which is especially suitable for long through-type headlights. Depending on the actual structural layout and installation requirements, each adjustment mechanism can be installed independently on a separate headlight mounting foot to achieve segmented support; alternatively, at least two adjustment mechanisms can be integrated and installed on the same headlight mounting foot to simplify the local structure, concentrate stress, and improve space utilization and assembly flexibility. In this embodiment, there are eight first adjustment mechanisms 2, and two second adjustment mechanisms 3 and two third adjustment mechanisms 4. The two second adjustment mechanisms 3 and the two third adjustment mechanisms 4 are respectively located at both ends of the integrated headlight assembly 1 along the second direction. The second adjustment mechanisms 3 and the third adjustment mechanisms 4 located at the same end are integrated and installed on the same headlight mounting foot. By combining multi-point up-and-down adjustment with end-to-end and lateral fine-tuning, precise control of the three-dimensional posture of the long headlight body can be achieved, ensuring uniform fit and consistent gaps with surrounding components, while taking into account both structural strength and assembly feasibility.

[0037] Please see Figure 4 and Figure 5In one embodiment, the integrated headlight assembly 1 includes a lamp housing 11, a lamp cover 12, a light source assembly 13, a first thick-walled member 14, a second thick-walled member 15, a first decorative ring 16, and a second decorative ring 17. The lamp housing 11 and the lamp cover 12 are connected to form a receiving cavity 18. The lamp cover 12 is provided with a light-transmitting area 121. The light source assembly 13, the first thick-walled member 14, the second thick-walled member 15, the first decorative ring 16, and the second decorative ring 17 are all located within the receiving cavity 18. The light source assembly 13 is used to emit light. The lamp housing 11, the lamp cover 12, the first thick-walled member 14, the second thick-walled member 15, the first decorative ring 16, and the second decorative ring 17 are all integrally formed parts. The light source assembly 13 is connected to the first thick-walled member 14. The first thick-walled member 14, the second thick-walled member 15, the first decorative ring 16, and the second decorative ring 17 are all connected to the lamp housing 11. The lamp housing 11 is provided with a headlight mounting foot. The first thick-walled member 14 is provided with a focusing area on the side facing the light source assembly 13. The light source 141 has a reflective surface 142 and a first light-emitting surface 143 on the first thick-walled member 14. The second thick-walled member 15 has an incident light surface 151 at one end near the first light-emitting surface 143 and a second light-emitting surface 152 at the other end away from the first light-emitting surface 143. The second light-emitting surface 152 faces the light-transmitting area 121 so that the light emitted by the light source assembly 13 is focused by the light source 141 and then incident on the reflective surface 142 and reflected to the first light-emitting surface 143 before being emitted. The emitted light passes through the incident light surface 151 into the second thick-walled member 15 and is emitted from the second light-emitting surface 152 into the light-transmitting area 121. Specifically, the lamp housing 11, lamp cover 12, first thick-walled member 14, second thick-walled member 15, first decorative ring 16 and second decorative ring 17 are all integrally molded parts, that is, they all extend continuously along the lateral side of the vehicle to form a through-type integral structure to achieve the extension and integration effect of the front face visual. The light source assembly 13 is used to emit light. It is connected to the first thick-walled member 14 and achieves optical guidance and distribution through the first thick-walled member 14. The light propagation path is as follows: the light emitted by the light source assembly 13 is focused by the concentrator 141 and then incident on the reflective surface 142 of the first thick-walled member 14. After reflection, it exits from the first light-emitting surface 143, then enters the interior of the second thick-walled member 15 through the light-incident surface 151, and finally exits from the second light-emitting surface 152 and emits light through the light-transmitting area 121. This optical structure, through the coordinated light-guiding design of the first thick-walled member 14 and the second thick-walled member 15, achieves efficient transmission and uniform distribution of light over a long distance of the lamp body, ensuring continuous optical effect and no dark areas when the through-type light strip is lit. Meanwhile, the first thick-walled component 14, the second thick-walled component 15, the first decorative ring 16, and the second decorative ring 17 are all connected to the lamp housing 11, enhancing the stability and sealing of the internal structure. The lamp mounting feet on the lamp housing 11 are used to connect with the vehicle body and, together with the adjustment mechanism, realize the spatial posture adjustment of the lamp body. The overall structure ensures the continuity of light emission while taking into account optical efficiency, structural strength, and assembly reliability.

[0038] Please see Figure 5 In one embodiment, the first light-emitting surface 143 is provided with a first pattern 1431; and / or, the light-incident surface 151 is provided with a second pattern 1511; and / or, the second light-emitting surface 152 is provided with a third pattern 1521. Specifically, this design achieves further control of light by providing patterned structures on key light-emitting or light-incident surfaces in the optical path. The first pattern 1431, located on the first light-emitting surface 143 of the first thick-walled member 14, can be used to scatter or diffuse the concentrated light output from the reflective surface 142, improving light intensity distribution and avoiding local bright spots. The second pattern 1511, located on the light-incident surface 151 of the second thick-walled member 15, can perform primary light homogenization when light is coupled from the first thick-walled member 14 into the second thick-walled member 15, improving the uniformity of light energy distribution. The third pattern 1521, located on the second light-emitting surface 152, can soften and diffuse the finally emitted light, making the light emission effect of the light-transmitting area 121 more uniform and softer, improving visual quality. The various patterns can take the form of microprisms, dots, frosted textures, or freeform surface arrays, and their density, depth, and distribution can be designed according to actual optical requirements. By selectively setting patterns on different optical interfaces, the overall lighting effect of the through-type light strip can be effectively optimized without adding additional optical components, ensuring consistency and aesthetics of long-distance light output.

[0039] Please see Figure 5In one embodiment, the light source assembly 13 includes a substrate 131 and a light-emitting element 132. The substrate 131 and the light-emitting element 132 are electrically connected. The substrate 131 is detachably connected to the first thick-walled member 14. The light-emitting element 132 is disposed facing the condenser 141 and is used to emit light. And / or, the first thick-walled member 14, the second thick-walled member 15, the first decorative ring 16, and the second decorative ring 17 are all detachably connected to the lamp housing 11, and the lamp housing 11 is sealed to the lamp shade 12. Specifically, this structure, by making the substrate 131 and the first thick-walled member 14 detachably connected, facilitates the installation, replacement, and maintenance of the light source assembly 13. When the lamp reaches the end of its lifespan or experiences light decay or damage, it is not necessary to replace the entire lamp body; only the substrate 131 needs to be removed for maintenance, improving maintenance convenience and economic efficiency. Simultaneously, the light-emitting element 132 is arranged facing the condenser 141 to ensure efficient coupling of light into the first thick-walled member 14, improving optical utilization efficiency. Furthermore, the first thick-walled component 14, the second thick-walled component 15, the first decorative ring 16, and the second decorative ring 17 are all detachably connected to the lamp housing 11 (e.g., via screws or connectors), allowing each functional component to be assembled and adjusted independently. This facilitates modular operations during production, reduces assembly difficulty, and makes it easier to clean, replace, or upgrade individual components. The lamp housing 11 and the lamp shade 12 are connected by a sealed connection (e.g., via hot melt adhesive, sealing rings, or laser welding) to form a sealed cavity 18, effectively preventing external moisture and dust from entering the cavity, avoiding contamination of optical components or short circuits in electronic components, and significantly improving the environmental tolerance and long-term reliability of the lamp. The overall structure, while ensuring optical performance and appearance quality, also considers maintainability, assembly flexibility, and sealing safety, making it suitable for demanding automotive lighting applications. In this embodiment, the substrate 131 is fixed to the first thick-walled member 14 from bottom to top with screws; the first thick-walled member 14 is fixed to the rear and bottom of the lamp housing 11 with screws; the first decorative ring 16 and the second decorative ring 17 are fixed to the lamp housing 11 together with the second thick-walled member 15 by screws; the lampshade 12 and the lamp housing 11 are sealed and installed by hot melt adhesive to ensure a firm connection and reliable sealing.
