[0032] Please refer to the reference. Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of an embodiment of the vehicle taillight provided in this application. Figure 2 yes Figure 1 A schematic diagram of the cross-sectional structure of the first decorative ring portion of the center mask. In one aspect of this application, a vehicle taillight 100 is provided, the taillight including a mask 1. The mask 1 includes a first panel 11, a second panel 12, and a first decorative ring 13. The second panel 12 covers one side of the first panel 11, and the first decorative ring 13 is fixedly connected to the other side of the first panel 11 and together with the first panel 11 and the second panel 12 forms a cavity 14. The first panel 11 is provided with a panel retaining rib 111, and the edge of the first decorative ring 13 is provided with a hook 131, the hook 131 also having a notch 132. The panel retaining rib 111 is located within the cavity 14 and interlocks with the hook 131, covering the notch 132. The notch 132 communicates with the cavity 14 through the assembly gap between the hook 131 and the panel retaining rib 111. In this embodiment, the first decorative ring 13 can be welded to the first panel 11 to form an integral structure. The slag produced during welding is called welding slag. By fixing the first decorative ring 13 to the first panel 11 and setting the panel baffle 111, the welding slag produced by the connection between the first decorative ring 13 and the first panel 11 can be shielded, improving or avoiding the problem of visible welding slag caused by the gap between the decorative ring and the mask 1 in the prior art, and improving the aesthetic appearance of the vehicle taillight 100. At the same time, the design of the notch 132 allows the cavity 14 formed after the connection to circulate with the outside air, which can not only discharge slag and debris, but also promote the rapid dissipation of fog, solving the risk of fogging in a confined space, further improving the long-term visual effect and overall quality of the vehicle taillight 100, thereby enhancing the vehicle's appearance recognition and brand value.

[0033] Specifically, the face shield 1 includes a first panel 11, i.e., the black sheet of the face shield 1, which serves as the basic supporting component of the taillight structure; a second panel 12, i.e., the white sheet of the face shield 1, which covers one side of the first panel 11 to form an illumination window; and a first decorative ring 13, i.e., a logo decorative ring, which can be connected to the first panel 11 by welding. A panel retaining rib 111 is a structure located at the edge of the first panel 11, the width of which matches the gap between the first decorative ring 13 and the first panel 11, effectively covering the gap area and preventing the exposure of weld slag, etc. A notch 132 is a structure located on the first decorative ring 13, which can be two openings at the top and bottom ends, communicating with the cavity 14. By setting a notch 132 on the trim ring and cooperating with the panel retainer 111 to form a channel for the discharge of slag and debris, the problem of visible welding slag is further improved or avoided, enhancing the aesthetics of the design. Simultaneously, the notch 132 structure allows airflow between the cavity 14 and the outside, accelerating fog dissipation and preventing internal fogging. This improves the clarity of the vehicle taillight 100 under various environmental conditions and enhances its appearance quality over long-term use, thereby increasing the overall refinement of the vehicle's design and brand value. It should be noted that, to improve the flowability of the notch 132, the panel retainer 111 can be disconnected at the position corresponding to the notch 132, allowing the notch 132 to connect directly to the first panel 11, thus increasing the size of the notch 132.

[0034] In one specific embodiment, the width of the panel retaining rib 111 can be designed to be 0.5 mm to 1 mm to accommodate the gap. For example, laser welding process can be used to achieve the welding connection between the first decorative ring 13 and the first panel 11. The notch 132 can be circular or rectangular and located at the upper and lower ends of the first decorative ring 13 to form a passage with the cavity 14.

[0035] like Figure 3 As shown, Figure 3 yes Figure 2 A schematic diagram of the structure of the first decorative ring 13. In one embodiment of this application, the first panel 11 is provided with a first through hole 15, and the second panel 12 and the first decorative ring 13 both cover the first through hole 15 to form a cavity 14. The first panel 11 bends and extends from the edge of the first through hole 15 toward the direction of the first decorative ring 13 to form a panel retaining rib 111. The first decorative ring 13 bends and extends from the edge toward the direction of the first panel 11 to form a hook 131. A notch 132 is provided on the side of the hook 131 facing the panel retaining rib 111.

[0036] Specifically, the cavity 14 can be formed by the second panel 12, the first decorative ring 13, and the first panel 11 together. The edge of the first decorative ring 13 is provided with a hook 131, which can be a protruding structure on the edge of the decorative ring, used to mechanically engage with the panel retaining rib 111 on the first panel 11. The hook 131 is a structural component on the edge of the first decorative ring 13, and the notch 132 is achieved by processing a recessed area on the outer edge of the hook 131, for example, by using an injection molding process to pre-form a recessed groove on the hook 131; the panel retaining rib 111 is a protruding structure on the edge of the first panel 11, formed by integral molding during panel manufacturing or subsequent welding reinforcement; when the hook 131 and the panel retaining rib 111 are fixedly connected, the notch 132 and the panel retaining rib 111 are physically matched to form a continuous notch 132 channel, and at the same time, the engagement of the hook 131 and the panel retaining rib 111 covers the gap between the first decorative ring 13 and the first panel 11. In one specific embodiment, the hook 131 can be integrally formed by the injection molding of the first decorative ring 13, and the material is ABS engineering plastic. The width and gap of the panel baffle 111 are precisely matched so that the welding slag is completely covered and there are no visible gaps.

[0037] Furthermore, the snap-fit ​​between the hook 131 and the panel retaining rib 111 conceals the gap between the first decorative ring 13 and the first panel 11, improving or preventing the problem of weld slag from being exposed through the gap during welding, thereby enhancing the aesthetic appeal of the taillights. Moreover, since no additional fixing structure is required, not only is weight and cost reduced, but the surface of the vehicle taillights 100 is also made smooth and flawless, further enhancing the overall character and brand value of the vehicle.

[0038] In one specific embodiment, the extension direction of the notch 132 may intersect with the extension direction of the hook 131. For example, the extension direction of the notch 132 may be perpendicular to the extension direction of the hook 131, so that the opening of the formed notch 132 faces outward, thereby allowing the cavity 14 to communicate with the outside. The shape of the notch 132 may be circular or rectangular to facilitate slag discharge, air circulation, and simplify construction.

[0039] In one embodiment of this application, please continue to combine Figure 2 The vehicle taillight 100 also includes a housing 2, which is welded and fixed to the first panel 11; a receiving cavity 3 is formed between the housing 2 and the first panel 11, and a notch 132 connects the cavity 14 and the receiving cavity 3.

[0040] Specifically, the housing 2 is typically made of metal or engineering plastic and is firmly connected to the first panel 11 via welding processes such as ultrasonic welding or laser welding to form a sealed accommodating cavity 3. The notch 132 is designed to match the slag discharge channel at the edge of the cavity 14, allowing slag generated during welding to flow smoothly into the accommodating cavity 3 and preventing it from remaining inside the cavity 14. The formation of the accommodating cavity 3 not only provides a discharge path for slag but also facilitates the integration of components such as desiccants, enhancing moisture resistance, extending the taillight's lifespan, and simplifying the manufacturing process. This allows the taillight to better reflect the vehicle brand's high-end design positioning while meeting safety regulations. Furthermore, the housing 2 can also contain components such as a light source to provide light and achieve the function of illumination.

[0041] In one embodiment of this application, the accommodating cavity 3 is provided with a first desiccant 33 and a second desiccant 34, wherein the drying speed of the first desiccant 33 is greater than the drying speed of the second desiccant 34; the first desiccant 33 is positioned directly opposite to and close to the notch 132, and the second desiccant 34 is positioned away from the notch 132.

[0042] Specifically, due to the rapid moisture absorption characteristics of the first desiccant 33, its position is set close to the notch 132 to quickly deal with the initial moisture generated during the manufacturing or use of the taillight, preventing internal condensation from affecting light transmittance and the clarity of signal indication. Due to the slow moisture absorption characteristics of the second desiccant 34, its position is set far away from the notch 132 to provide a long-lasting drying effect, prevent the desiccant from becoming saturated and failing prematurely, effectively inhibit internal component corrosion and fogging, thereby improving the long-term reliability and service life of the vehicle taillight 100, while ensuring that the taillight maintains stable optical performance and aesthetic appearance under various climatic conditions.

[0043] In one embodiment of this application, the inner wall of the accommodating cavity 3 is provided with a support 21, which divides the accommodating cavity 3 into a first accommodating area 31 and a second accommodating area 32 that are interconnected. The first desiccant 33 is fixed in the first accommodating area 31 and the second desiccant 34 is fixed in the second accommodating area 32.

[0044] Specifically, the cavity 3 is equipped with a first accommodating zone 31 and a second accommodating zone 32 at intervals to achieve differentiated desiccant configuration. The first accommodating zone 31 can use materials with faster drying speeds, such as silica gel or calcium chloride, while the second accommodating zone 32 can use materials with slower drying speeds, such as molecular sieves or activated carbon. This enables rapid initial moisture absorption to prevent condensation, and continuous drying in the later stages to maintain environmental stability. Alternatively, the first desiccant 33 can be made into small particles to increase the surface area and accelerate moisture absorption, while the second desiccant 34 can be designed as large particles or a slow-release structure to slow down the moisture absorption rate. Or, in practical applications, the chemical composition of the desiccant can be adjusted, for example, by adding highly hygroscopic substances to the first desiccant 33 and polymer matrices to the second desiccant 34 to control the release rate, thereby precisely matching the moisture management needs at different stages.

[0045] In one specific embodiment, the support 21 includes a first isolation rib 211 and a second isolation rib 212 extending into the accommodating space. The two first isolation ribs 211 and the inner wall of the accommodating cavity 3 together form a first accommodating area 31; the two second isolation ribs 212 and the inner wall of the accommodating cavity 3 together form a second accommodating area 32, thereby making the first accommodating area 31 and the second accommodating area 32 independent of each other, reducing the risk of mutual interference, and also simplifying the structure and reducing costs.

[0046] Please continue to refer to the reference. Figure 1 , Figure 4 and Figure 5 , Figure 4 yes Figure 1 A schematic diagram of the structure of the middle mask 1. Figure 5 yes Figure 1 A partial cross-sectional structural diagram of the structure after the second decorative ring 4, decorative element 5, printed circuit board 7, and reflector 8 are assembled. In one embodiment of this application, the vehicle taillight 100 further includes a second decorative ring 4, decorative element 5, and light-blocking bracket 6; the mask 1 is also provided with a second through hole 16, which penetrates the first panel 11 and the second panel 12, and is located on the side of the mask 1 away from the first decorative ring 13; the second decorative ring 4 is installed in the second through hole 16, the second decorative ring 4 is provided with a mounting through hole 41, the decorative element 5 and the light-blocking bracket 6 are stacked and installed in the mounting through hole 41, and the edge of the light-blocking bracket 6 is at least aligned with the edge of the mounting through hole 41.

[0047] Specifically, the face mask 1 in this embodiment may include two parts, one large and one small, connected to each other. The smaller part has a first through hole 15 for installing a first decorative ring 13, and the larger part has a second through hole 16 for installing a second decorative ring 4. The second decorative ring 4 may be made of engineering plastic or metal and has an installation through hole 41. The decorative element 5 is made of metal or plastic and can be fixed to the light-blocking bracket 6 by snap-fit. The light-blocking bracket 6 and the decorative element 5 are stacked to block the gap between the decorative element 5 and the second decorative ring 4. During installation, after the light-blocking bracket 6 and the installation through hole 41 of the second decorative ring 4 are aligned, the light-blocking bracket 6 is embedded therein. After the decorative element 5 and the light-blocking bracket 6 are snap-fitted, they are stacked together and installed in the installation through hole 41. Since the edge of the light-blocking bracket 6 is at least aligned with the edge of the installation through hole 41, the light-blocking bracket 6 can completely cover the gap area between the decorative element 5 and the installation through hole 41. For example, the mounting hole 41 of the second decorative ring 4 can be designed as a circle or an oval to match the structure of the light-blocking bracket 6, so as to avoid misalignment during installation. At the same time, the shape of the decorative part 5 can be customized as a streamlined shape or a brand logo pattern, such as an "o" shape, to enhance the visual sense of layering.

[0048] Furthermore, by using the light-blocking bracket 6 to shield the gap between the decorative piece 5 and the second decorative ring 4, light leakage from this gap is effectively prevented, avoiding light spots, stray light, or dark areas on the taillight surface, significantly improving the aesthetics and visual consistency of the taillight. In the actual use of the vehicle taillight 100, this design not only meets the safety regulations' requirements for light distribution but also enables the taillight to present a purer and more advanced light effect at night or under complex lighting conditions, enhancing the overall vehicle recognition and brand image, thereby directly improving consumer satisfaction with the product's appearance and their willingness to purchase, creating a differentiated advantage for vehicle manufacturers in market competition.

[0049] In one embodiment of this application, as Figure 5 As shown, the decorative component 5 includes a first end 51 and a second end 52 that are adjacent and have different directions. The first end 51 is fixedly connected to the first panel 11 through an inclined slope, and the second end 52 is snapped and fixed to the light-blocking bracket 6.

[0050] Specifically, the first end 51 and the second end 52 of the decorative piece 5 are designed to be adjacent but oriented in different directions, allowing for flexible adjustment of the angle of the decorative piece 5 during installation to match the overall shape of the taillight. The first end 51 can be fixedly connected to the first panel 11 by welding, specifically using laser spot welding or ultrasonic welding technology, ensuring a firm connection without obvious protrusions to avoid affecting the appearance. The second end 52 is fixed to the light-blocking bracket 6 by a snap-fit ​​mechanism. The light-blocking bracket 6 has a dedicated slot structure, allowing for quick positioning and installation after the second end 52 of the decorative piece 5 is inserted into the slot.

[0051] Furthermore, due to dimensional tolerances and other reasons, a gap may be formed at the connection between the first end 51 and the first panel 11. Therefore, the connection surface between the first end 51 and the first panel 11 can be an inclined slope, so that the extension direction of the gap formed between the two is inclined, thereby reducing the width B of the gap so that the projection of the light-blocking bracket 6 can cover the gap.

[0052] Please continue to combine Figure 6 , Figure 6 yes Figure 5 A magnified structural diagram of part A in the middle. In one embodiment of this application, the light-blocking bracket 6 is provided with a light-blocking rib 61, which extends to the edge of the light-blocking bracket 6, and the extension length H of the light-blocking rib 61 is at least greater than the gap width B between the edge of the mounting through hole 41 and the decorative piece 5.

[0053] Specifically, the light-blocking rib 61, as a key structure of the light-blocking bracket 6, extends in the same direction as the first end 51 of the decorative piece 5, effectively covering the gap between the first panel 11 and the decorative piece 5. The light-blocking rib 61 can be integrally molded onto the light-blocking bracket 6 using injection molding, with weather-resistant ABS plastic as the material to adapt to the vehicle's external environment. The extension length H of the light-blocking rib 61 can be set to be 0.3 to 0.8 mm larger than the gap width B. For example, when the gap width B is 0.5 mm, the extension length H of the light-blocking rib 61 is 0.8 mm, thus completely covering the gap area. Of course, the extension length H of the light-blocking rib 61 cannot be too short or too long. If it is too short, it will not completely block the gap; if it is too long, it will block too much light, creating a very obvious dark area on the second decorative ring 4, severely affecting the aesthetics. During installation, the second end 52 of the decorative piece 5 is engaged with the light-blocking bracket 6, and the first end 51 is fixed to the first panel 11 by welding. The extended length of the light-blocking rib 61 allows the blocking range to exceed the gap boundary, thus avoiding local light leakage caused by assembly tolerances or material deformation.

[0054] The design of the light-blocking rib 61 extending in length H to be greater than the gap width B effectively prevents light from passing through, avoiding uneven halo or light spot phenomena when the taillights are working at night, significantly improving the visual aesthetics and overall quality of the taillights. Furthermore, the extension length H of the light-blocking rib 61 cannot be too short or too long. This precise dimensional control ensures the sealing of the joint between the decorative part 5 and the third panel, making the taillight's appearance lines more concise and smooth, meeting the stringent requirements of high-end vehicles for detail design. At the same time, it reduces user concerns about product reliability caused by light leakage, enhancing the market competitiveness and user satisfaction of the vehicle's taillights.

[0055] Please continue to combine Figure 7 and Figure 8 , Figure 7 yes Figure 1 A schematic diagram of the structure of the second decorative ring 4, decorative piece 5, printed circuit board 7, and reflector 8 before assembly. Figure 8 yes Figure 1 A schematic diagram of the structure of the reflector 8. In one embodiment of this application, the vehicle taillight 100 further includes a printed circuit board 7 and a reflector 8. The reflector 8 is mounted on the housing 2, and the printed circuit board 7 is screwed onto the reflector 8. The printed circuit board 7 is provided with a mounting hole 71, and the reflector 8 is provided with a positioning post 81. The positioning post 81 passes through the mounting hole 71 and is connected and fixed to the light-blocking bracket 6.

[0056] Specifically, a reflector 8 made of metal or engineering plastic can be used, and the reflector 8 is fixed to the corresponding position of the housing 2 with screws; the printed circuit board 7 is screwed to the surface of the reflector 8 to achieve a stable installation of electrical components; the mounting hole 71 of the printed circuit board 7 can be designed as a circular through hole, and the positioning post 81 of the reflector 8 can be a cylindrical protrusion with a diameter matching the mounting hole 71. After the positioning post 81 passes through the mounting hole 71, it is fixed to the light-blocking bracket 6 by a threaded connection to achieve precise alignment; in a specific implementation, the length of the positioning post 81 can be slightly longer than the thickness of the printed circuit board 7 to improve or avoid relative displacement under vehicle vibration environment. At the same time, the snap-fit ​​structure of the light-blocking bracket 6 and the positioning post 81 can also work together to avoid misalignment or loosening during assembly.

[0057] This structural design, through the precise fit between the positioning post 81 and the mounting hole 71, prevents the printed circuit board 7 from shifting due to vibration during vehicle operation, thus improving the reliability of electrical connections. The screw-on installation method provides a firm mechanical fixation, reducing the risk of loosening due to long-term use and extending the lifespan of the taillight. The direct connection and fixation between the positioning post 81 and the light-blocking bracket 6 integrates the optical components and circuit components into a stable whole, simplifying the assembly process, reducing production costs, and ensuring that the taillight maintains a high aesthetic appeal while meeting the signal indication function required by safety regulations. It also avoids lighting failure or visual defects caused by loose components, thereby improving the safety performance and market competitiveness of the vehicle taillight 100 in practical applications.

[0058] During assembly, the printed circuit board 7 is first installed on the reflector 8 with three screws. Then, the positioning post 81 is screwed through the pre-drilled mounting hole 71 on the printed circuit board 7 and fixed to the light-blocking bracket 6. After that, the second decorative ring 4 can be installed on the reflector 8 with three screws and a clip. At the same time, the mounting through hole 41 corresponds to the light-blocking bracket 6. Finally, the decorative part 5 can be clipped onto the light-blocking bracket 6 with two clips and connected and fixed to the edge of the mounting through hole 41, thus completing the assembly of this part of the structure.

[0059] In another embodiment of this application, unlike the above embodiment, the first panel 11 is provided with a glue groove (not shown in the figure). The glue groove is located at the edge of the cavity 14 and engages with the first decorative ring 13. Glue is poured into the glue groove to fix the first panel 11 and the first decorative ring 13 together.

[0060] Specifically, a matching groove structure can be designed on the edge of the first panel 11 to create a tight fit between the groove and the outer edge of the first trim ring 13. For example, the depth and angle of the groove can be adjusted to fit the protruding part of the first trim ring 13. During assembly, the groove of the first panel 11 is aligned with the engagement position of the first trim ring 13, and polyurethane glue or epoxy resin is injected. After the glue has fully cured, a stable connection is achieved. By using the groove engagement and glue injection fixation method, the problem of unsightly internal edges of the taillight caused by weld slag residue in traditional welding processes is solved, keeping the edge of the cavity 14 clean and smooth, significantly improving the visual texture and overall design of the vehicle taillight 100. The glued connection provides uniform bonding strength, avoiding component loosening or cracking that may be caused by stress concentration at the welding point, and enhancing the structural stability of the vehicle taillight 100 under vibration and temperature change environments, thereby meeting the dual requirements of vehicle exterior design for detail refinement and long-term reliability.

[0061] In another aspect, this application also provides a vehicle that includes the aforementioned taillight 100. Specifically, since the vehicle includes the taillight 100 described in the above embodiment, it also has the beneficial effects of the aforementioned taillight 100, which will not be repeated here.

[0062] It should be noted that the terms "horizontal" and "vertical" do not imply that the components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. Similarly, the terms "parallel" and "perpendicular" do not imply that the components are absolutely parallel or perpendicular, but rather that they can have a certain angular deviation. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted. In addition, the orientations or positional relationships indicated by terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" are based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships that are commonly used when the product of this application is in use. They are only for the purpose of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0063] It is understood that the term "multiple" in this document means at least two, such as two, three, etc., unless otherwise specified. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices. The term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects are in an "or" relationship.

[0064] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
