Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to a novel multifunctional automotive rear combination lamp. Background Technology

[0002] With economic development and improved living standards, vehicles have become deeply integrated into daily life. Vehicle manufacturers, parts suppliers, and users are no longer only focusing on vehicle performance, safety, and fuel economy, but also placing higher demands on the multi-functional integration and aesthetic appeal of automotive parts.

[0003] The design of automotive rear combination lights must simultaneously meet the requirements of functional integration, streamlined appearance, and reliability. Chinese patent CN210069733U discloses a vehicle lighting optical system and taillight, which integrates position lights, brake lights, and turn signals within a compact space through structures such as light guides, light-distributing lenses, and reflector arrays, simplifying the vehicle lighting structure. However, this taillight still has significant shortcomings in practical applications, failing to simultaneously meet the requirements of vehicle assembly economy, appearance integrity, and reliability. Specific deficiencies are as follows: 1. To adapt to the streamlined design of the vehicle, the taillight's A-side has a large curvature, but no space is reserved inside for side marker lights. Side marker lights must be added separately to the side of the vehicle to meet lateral position recognition requirements, increasing the vehicle assembly process and cost; 2. When the lamp housing and lamp cover are welded together, the large curvature design easily causes the outer edge of the injection-molded lamp housing to deform outwards, causing the weld ribs at the outward-curving points to deviate from their preset positions during welding, leading to incomplete welds. The problem ultimately leads to a water leakage hazard in the taillights during use, affecting the lifespan of the lights and driving safety; 3. The entire optical system can be mounted on the mounting bracket, resulting in a large weight on the mounting bracket. The mounting bracket is fixed to the lamp housing by mounting posts and external screws. The mounting posts that lock the screws are localized stress structures, bearing the weight of the optical system for a long time. Moreover, the vibration during vehicle operation will aggravate the fatigue damage of the mounting posts, which can easily lead to the failure of the mounting posts, resulting in problems such as optical system displacement and abnormal lamp function, seriously affecting the reliability of the lamps.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] according to Figure 1-7As shown, a novel multi-functional automotive rear combination lamp includes a lamp housing 1, a lamp cover 2, and an optical assembly 3. The lamp housing 1 and the lamp cover 2 are welded together to form a sealed cavity. The optical assembly 3 is disposed within the cavity and includes a first position light optical unit 32, a brake light optical unit 33, a turn signal light optical unit 34, a second position light optical unit 35, a reversing light optical unit 36, a rear retroreflective optical unit 37, and a side marker light optical unit 38. The first position light optical unit 32 is L-shaped, and the brake light optical unit 33 is strip-shaped, together forming a first trapezoidal structure. The second position light optical unit 35 is L-shaped, and the reversing light optical unit 36 ​​is strip-shaped, together forming a second trapezoidal structure. The first trapezoidal structure is located above the second trapezoidal structure. The side marker light optical unit 38 directly provides lateral position recognition functionality, eliminating the need for additional side marker lights on the side of the vehicle, reducing assembly steps and lowering production costs. The reversing light optical unit 36 ​​and the rear retroreflective optical unit 37 improve the coverage of lighting functions, enhancing both the clarity of illumination when reversing and the passive warning effect during driving, thus comprehensively ensuring travel safety. The combination of L-shaped and strip-shaped elements allows for a more compact layout of the optical units, effectively saving internal design space while balancing aesthetics and space utilization.

[0030] Specifically, the optical assembly 3 also includes a decorative frame 31. The first position lighting optical unit 32, brake light optical unit 33, turn signal optical unit 34, second position lighting optical unit 35, reversing light optical unit 36, rear retroreflective optical unit 37, and side marker light optical unit 38 are all or partially mounted on the decorative frame 31, with the remainder mounted on the lamp housing 1. In this embodiment, to reduce the overall weight of the decorative frame 31 and prevent it from being easily damaged later, some optical units are mounted on the decorative frame 31, while the remaining optical units are mounted on the lamp housing 1. The decorative frame 31 is provided with a first mounting groove 3111, a second mounting groove 3112, a first light-emitting hole 3113, a second light-emitting hole 3114, a third mounting groove 3115, a third light-emitting hole 3116, and a fourth light-emitting hole 3117. The rear retroreflective optical unit 37 is mounted in the first mounting groove 3111, the first position light optical unit 32 is mounted in the second mounting groove 3112, and the second position light optical unit 35 is mounted in the third mounting groove 3115. The decorative frame 31 is mounted on the lamp housing 1. The brake light optical unit 33, the turn signal light optical unit 34, the reversing light optical unit 36, and the side marker light optical unit 38 are all mounted on the lamp housing 1 behind the decorative frame 31, such that the brake light optical unit 33 corresponds to the first light-emitting hole 3113, the turn signal light optical unit 34 corresponds to the second light-emitting hole 3114, the reversing light optical unit 36 ​​corresponds to the third light-emitting hole 3116, and the side marker light optical unit 38 corresponds to the fourth light-emitting hole 3117.

[0031] To further save internal design space of the lamp, the decorative frame 31 includes a main body area 311 and a beveled area 312. The beveled area 312 is integrally set on the outer edge of the main body area 311 and extends diagonally backward. The main body area 311 is provided with a first mounting groove 3111, a second mounting groove 3112, a first light-emitting hole 3113, a second light-emitting hole 3114, a third mounting groove 3115, and a third light-emitting hole 3116 from top to bottom. The beveled area 312 is provided with a fourth light-emitting hole 3117. By setting the beveled area 312 extending diagonally backward on the outer edge of the main body area 311 to add the position of the fourth light-emitting hole 3117, the design space of other optical units is avoided.

[0032] To avoid direct visibility of the light source from outside the lamp and prevent glare, thereby improving user comfort, the side marker light optical unit 38 includes a side marker light LED light source board 381. The lamp housing 1 has an insertion slot 12, and a screw post is located on one side of the insertion slot 12. The side marker light LED light source board 381 is inserted into the insertion slot 12 and abuts against it via an L-shaped plastic pressure plate 10. A screw passes through the L-shaped plastic pressure plate 10 and connects to the screw post, thus fixing the side marker light LED light source board 381 to the lamp housing 1. The light provided by the side marker light optical unit 38 is emitted through the fourth light outlet 3117. A small yellow cover 4 is also snapped onto the inclined area 312. The small yellow cover 4 is used to cover the fourth light outlet 3117. The inner surface of the small yellow cover 4 is provided with a side retroreflection pattern area and a light distribution pattern area. The light distribution pattern area is used to optimize the light provided by the side marker light LED light source board 381, and at the same time, it can prevent the light source from being directly seen outside the lamp, thus preventing glare. The side retroreflection pattern area is used to enhance the passive warning effect during driving, and comprehensively ensure travel safety. The first position light optical unit 32 includes a first position light LED light source board 321 and a first red cover 322. The first position light LED light source board 321 is fixed in the second mounting groove 3112. The first red cover 322, made of semi-transparent material, is installed on the top of the groove of the second mounting groove 3112, covering the second mounting groove 3112. The second position light optical unit 35 has a similar structure to the first position light optical unit 32, and will not be described in detail here. The brake light optical unit 33 includes a brake light LED light source board 331 and a brake concentrator 332. The brake light LED light source board 331 is mounted on the brake concentrator 332 and is mounted on the lamp housing 1 via the brake concentrator 332. The turn signal optical unit 34 has a similar structure to the brake light optical unit 33 and will not be described in detail here. The reversing light optical unit 36 ​​includes a reversing light reflector 361 and a reversing light LED light source board 362. The reversing light reflector 361 has a side-emitting structure. The reversing light LED light source board 362 is mounted on the reversing light reflector 361 and is fixed to the lamp housing 1 via the reversing light reflector 361. By using the brake concentrator 332, the side-emitting reversing light reflector 361, and the first red cover 322 made of semi-transparent material, the light source can be avoided from being directly seen in front of the lamp, effectively preventing glare and further improving user comfort. In this embodiment, the first position light LED light source board 321 is fixed in the second mounting groove 3112 with screws. The first red cover 322 is made of red semi-transparent material and is snapped onto the top of the groove of the second mounting groove 3112. The snap-fit ​​installation is convenient and quick. The light provided by the first position light LED light source board 321 is softened by the first red cover 322, which further improves the visual effect of the light and the comfort of use.The brake light LED light source board 331 is fixed to the brake concentrator 332 with screws, and the brake concentrator 332 is then fixed to the lamp housing 1 with screws. The brake concentrator 332 includes an input end and an output end. The light emitted by the brake light LED light source board 331 is collected and collimated by the input end and then homogenized and emitted by the output end, improving the visual effect of the light and the comfort of use. The reversing light LED light source board 362 is limited on the reversing reflector 361 by an L-shaped plastic pressure plate 10. Then, screws are used to pass through the L-shaped plastic pressure plate 10 and connect to the screw posts provided on the reversing light reflector 361, thereby fixing the reversing light LED light source board 362 to the reversing light reflector 361. The reversing light reflector 361 is then fixed to the lamp housing 1 with screws. The reversing light reflector 361 is provided with a grid reflective pattern, which reflects the light and avoids direct light, improving the comfort of use.

[0033] Furthermore, the decorative frame 31 is provided with multiple rearwardly extending mounting posts 313; the lamp housing 1 is provided with a corresponding number of mounting recesses 14, each with a mounting hole 141 in the center. A flat washer screw with a sealing ring is passed through the mounting hole 141 and connected to the mounting post 313, thereby fixing the decorative frame 31 to the lamp housing 1. A buffer rubber ring 9 is also provided between the decorative frame 31 and the mounting recess 14. Specifically, the buffer rubber ring 9 has self-adhesive at both ends. The buffer rubber ring 9 is fitted onto the mounting post 313, and both ends are bonded to the decorative frame 31 and the mounting recess 14 respectively through self-adhesive. The buffer rubber ring 9 can effectively alleviate vibration and impact, disperse the local stress borne by the mounting post 313, reduce fatigue damage, and thus prevent the mounting post 313 from breaking. At the same time, the buffer rubber ring 9 can also cooperate with the sealing ring to provide double sealing protection, further improving the sealing performance. In this embodiment, to improve the accuracy of the installation position, a limiting rib 142 is provided on the surface of the mounting platform 14 facing the decorative frame 31. The limiting rib 142 is located on the outer ring of the mounting hole 141 and is coaxial with the mounting hole 141. The mounting post 313 with a buffer rubber ring 9 is inserted into the limiting rib 142 and is limited by the limiting rib 142. Then, a flat washer screw with a sealing ring is used to pass through the mounting hole 141 and connect to the mounting post 313, thereby fixing the decorative frame 31 to the lamp housing 1. The buffer rubber ring 9 is made of silicone that is resistant to high and low temperatures and anti-aging. The thickness of the buffer rubber ring 9 is set according to the distance between the decorative frame 31 and the mounting platform 14, and the compression is controlled at 20%-30%. The sealing ring on the flat washer screw provides an external seal, and the buffer rubber ring 9 provides an internal seal. The two work together to provide double sealing protection, further improving the reliability of the lamp function.

[0034] Due to deformation during the production of the decorative frame 31 with a large curvature, the outer edge of the inclined area 312 may warp up and touch the lampshade 2. During use, the two rub against each other, generating debris inside the cavity. The inclined area 312 has several limiting inserts 5 on its outer edge, and the lamp housing 1 has several corresponding limiting slots 13 on the inner side of the welding rib 11. The limiting slots 13 cooperate with the limiting inserts 5 to prevent the outer edge of the inclined area from warping up. By cooperating with the limiting inserts 5, the limiting slots 13 and limiting slots 5 are used to position and adjust the inclined area 312, preventing the outer edge of the inclined area 312 from warping up and touching the lampshade 2 after installation. In this embodiment, the inclined area 312 has two limiting inserts 5 on its outer edge, and the lamp housing 1 has two corresponding limiting slots 13 on the inner side of the welding rib 11, ensuring the stability of the limiting adjustment.

[0035] Furthermore, multiple equally spaced buffer strips 8 are provided between the inclined area 312 and the lamp housing 1 to support the inclined area 312. Specifically, multiple equally spaced buffer strips 8 are integrally provided on the inner surface of the lamp housing 1 facing the inclined area 312. The outer surface of the buffer strips 8 is provided with an adhesive layer, which achieves flexible contact with the inclined area 312. By supporting the inclined area 312 with the buffer strips 8, the deformation of the decorative frame 31 due to its large curvature during production is offset, resulting in local concavity of the outer edge of the inclined area 312. This further improves the uniformity of the gap between the decorative frame 31 and the lamp housing 1, and the adhesive layer prevents hard contact between the two from causing wear, while also increasing vibration resistance. Specifically, several reinforcing structures 3121 are also provided on the inclined area 312 to structurally reinforce the inclined area 312, thereby reducing the amount of deformation. In this embodiment, the reinforcing structure 3121 is a triangular recessed platform. A triangular recessed platform is provided above the fourth light-emitting hole 3117 in the inclined area 312, and another triangular recessed platform is provided between the fourth light-emitting hole 3117 and the outer edge. The triangular recessed platforms increase the strength of the inclined area 312 and reduce the amount of deformation. The two triangular recessed platforms echo each other in shape, further improving the aesthetic appearance.

[0036] Furthermore, the lamp housing 1 has several limiting blocks 6 at the rear of the outer edge of the corresponding inclined area 312. The limiting blocks 6 are used to cooperate with the limiting grooves provided on the lamp housing welding mold. By cooperating with the limiting blocks 6 and the limiting grooves, the outer edge of the corresponding inclined area 312 of the lamp housing 1 is positioned and adjusted. By cooperating with the limiting blocks 6 and the limiting grooves, the outer edge of the corresponding inclined area 312 of the lamp housing 1 can be positioned and adjusted, effectively avoiding outward deformation of the outer edge after the injection molding of the large curvature lamp housing 1, thereby preventing the welding rib 11 at the outward deformation from deviating from the preset position during the welding process, thus preventing the weld from being incompletely welded, and further improving the reliability and service life of the welding seal. In this embodiment, two limiting blocks 6 are provided at the rear of the outer edge of the corresponding inclined area 312 of the lamp housing 1, and two limiting grooves are provided on the lamp housing welding mold to match them, further enhancing the limiting stability.

[0037] To improve the efficiency of mounting the lamp housing 1 onto the vehicle and on the lamp housing welding mold, a guide post 7 is provided at the rear of the outer edge of the lamp housing 1. The guide post 7 is used to cooperate with the guide holes provided on the lamp housing welding mold or the vehicle body sheet metal. Through the cooperation of the guide post 7 and the guide holes, the lamp housing 1 is guided during installation, quickly achieving the installation and positioning of the lamp housing 1, reducing the time spent on alignment and adjustment, and improving the convenience and accuracy of assembly.
