Description

TECHNICAL FIELD

[0002] As an important part of a vehicle, a tail light not only bears the functions of lighting and signal indication, but also gradually becomes an important element of the appearance design of a vehicle. In the prior art, an electric tail light is usually composed of a lamp shell and light-emitting components such as lamp beads and heat sinks installed inside the lamp shell. In order to meet the functions of local light shielding, local light transmission and waterproofing, the lamp shell of the tail light is usually designed as a whole shell structure and assembled and fixed with the light-emitting components.

[0056] Some embodiments of the application will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0057] First aspect

[0058] The application provides a tail lamp, comprising a lamp shell and a light emitting assembly mounted inside the lamp shell, with reference to Figure 1 , Figure 2 , Figure 4 , Figure 5 andFigure 6 The lamp shell of the tail lamp comprises a bottom shell assembly 100 and a surface shell 200; specifically, the bottom shell assembly 100 is internally provided with a mounting cavity for mounting a light-emitting assembly; the surface shell 200 comprises a transparent shell 22 and a connecting plate 21; the connecting plate 21 is located between the transparent shell 22 and the bottom shell assembly 100, and the connecting plate 21 is integrally formed with the transparent shell 22 or at least the edge portion of the connecting plate 21 is sealingly connected with the transparent shell 22; a positioning groove 2101 is arranged on the side surface of the connecting plate 21 away from the transparent shell 22, and a hollow portion 2102 is arranged at the position of the connecting plate 21 located in the positioning groove 2101. One end of the bottom shell assembly 100 through which light is emitted is inserted into the positioning groove 2101; the side wall of the positioning groove 2101 is sealingly connected with the bottom shell assembly 100.

[0059] It should be noted that, in the embodiment, the "one end of the bottom shell assembly 100 through which light is emitted" does not mean that the bottom shell assembly 100 can only emit light through one end, and does not mean that the light has a unique emission direction, but means that the bottom shell assembly 100 has a light-transmitting part allowing the light-emitting assembly inside to emit light, and the light-transmitting part allows the light to be emitted in all directions after being transmitted; the bottom shell assembly 100 has a butt joint end for butt joint with the positioning groove 2101, the butt joint end is inserted into the positioning groove 2101, and all or part of the light-transmitting part is distributed in the area of the butt joint end inserted into the positioning groove 2101, and the light-emitting assembly projects light outward through the hollow portion 2102 arranged on the connecting plate 21 and the transparent shell 22.

[0060] The embodiment can achieve the following beneficial effects:

[0061] On the one hand, the lamp shell is designed as a split structure composed of the bottom shell assembly 100 and the surface shell 200, the bottom shell assembly 100 serves as a general module and is responsible for mounting the light-emitting assembly; and the surface shell 200 serves as a replaceable module and can be independently designed into various shapes or patterns, greatly improving the modeling flexibility of the tail lamp. This design breaks through the limitation of the single modeling of the traditional integral lamp shell, not only can meet the needs of consumers for personalized appearance, but also can realize diversified tail lamp modeling by replacing the surface shell 200 when different models or different versions of the same model are updated, without the need to redevelop the entire lamp shell, reducing the repeated development work caused by model iteration or modeling update, reducing the research and development cost and mold cost, avoiding the overall waste of the lamp caused by model update, and reducing resource waste.

[0062] In another aspect, when the lamp shell is designed as a split structure composed of the bottom shell assembly 100 and the surface shell 200, the waterproof function can be reduced (which is the main reason why the prior art does not design a split lamp shell but mostly uses a whole lamp shell), and for this, the surface shell 200 is designed to be integrally formed with the connecting plate 21 and the transparent shell 22 or at least the edge of the connecting plate 21 is sealingly connected with the transparent shell 22, and the positioning groove 2101 and the hollow part 2102 are provided on the connecting plate 21, the partial light transmission of the surface shell 200 is ensured by the hollow part 2102 and the transparent shell 22, and the waterproof function of the light transmission area is ensured, and at the same time, the firm assembly between the surface shell 200 and the bottom shell assembly 100 is ensured and the gap between them is sealed by the plug-in design between the positioning groove 2101 on the connecting plate 21 and the bottom shell assembly 100 in combination with the sealing connection process, and the hollow part 2102 can be shaped as needed and to a certain extent, the positioning function between the surface shell 200 and the bottom shell assembly 100 is strengthened.

[0063] Therefore, by designing a split lamp shell, the lamp shell is divided into the bottom shell assembly 100 with strong universality and the surface shell 200 with customizable design, the problems of single tail lamp modeling, high cost and resource waste in the prior art are solved under the premise of ensuring functionality, the individualized appearance demand of the tail lamp is realized, and the flexibility and economy in the production process are also considered.

[0064] In some optional embodiments of the present embodiment, the connecting plate 21 and the transparent shell 22 are in a split structure, and at least the edge of the connecting plate 21 is sealingly connected with the transparent shell 22, and the sealing connection mode includes but is not limited to that the surfaces of the connecting plate 21 and the transparent shell 22 facing each other are bonded together by glue or are clamped together by concave-convex structures, and then the sealing glue covering the edge of the connecting plate 21 is sprayed between the edge of the connecting plate 21 and the transparent shell 22 to perform secondary sealing on the edge of the connecting plate 21 and the transparent shell 22; or a clamping groove matching the boundary of the connecting plate 21 is provided on the surface of the transparent shell 22 facing the connecting plate 21, a flange matching the boundary of the connecting plate 21 is provided on the edge of the connecting plate 21, a sealing glue strip is wrapped on the surface of the flange, the flange wrapped with the sealing glue strip is inserted into the clamping groove provided on the surface of the transparent shell 22, and the sealing between them is realized by the sealing glue strip, or other sealing modes are used for sealing.

[0065] In another optional embodiment of the present embodiment, the connecting plate 21 is integrally formed with the transparent housing 22, realizing seamless connection of the two, eliminating the gap and joint that may occur in the assembly process when the two are designed as separate parts, and improving the waterproof performance of the watchcase 200. In this optional embodiment, the connecting plate 21 is further optionally a colored plate, and the connecting plate 21 and the transparent housing 22 are integrally formed by two-color injection molding process, so as to realize different color visual effects of the outer shell by using different colors and types of material particles according to actual needs, for example but not limited to, two-color injection molding of the watchcase 200 by PMMA (polymethyl methacrylate) and colored ABS (acrylonitrile-butadiene-styrene copolymer). In the process, PMMA (polymethyl methacrylate) is injection molded into the transparent housing 22, and colored ABS (acrylonitrile-butadiene-styrene copolymer) is injection molded into the connecting plate 21. Of course, other colors or types of material particles can also be used for injection molding. Moreover, the two-color injection molding process can complete the molding of the transparent layer and the colored layer in one injection molding process, which can improve the production efficiency. In the process, the transparent housing 22 can also be designed with different curvatures and / or different patterns on the transparent housing 22 to meet different modeling needs.

[0066] In addition, in the present embodiment, for the positioning groove 2101 provided on the connecting plate 21, a groove can be directly formed on the side surface of the connecting plate 21 away from the transparent housing 22 to form the positioning groove 2101, or as shown in Figure 6 the connecting plate 21 away from the transparent housing 22 is provided with a limiting convex edge 211, and the limiting convex edge 211 surrounds the positioning groove 2101. The design of the limiting convex edge 211 surrounding the positioning groove 2101 can avoid the problem of reducing the structural strength of the connecting plate 21 by directly slotting the connecting plate 21, and it is also easier to position the bottom shell assembly 100 by using the protruding limiting convex edge 211, which is beneficial to quick assembly and improves the production efficiency.

[0067] For the specific sealing connection between the side wall of the positioning groove 2101 and the bottom shell assembly 100, a sealing strip can be arranged in the gap between the side wall of the positioning groove 2101 and the bottom shell assembly 100 to achieve sealing, or the side wall of the positioning groove 2101 and the bottom shell assembly 100 can be sealed and connected by sealing glue. Preferably, the side wall of the positioning groove 2101 and the bottom shell assembly 100 are sealed and connected by sealing glue. The sealing glue can form a continuous and dense sealing layer between the side wall of the positioning groove 2101 and the bottom shell assembly 100, effectively blocking the penetration of moisture and humidity. This sealing method avoids the sealing failure problem caused by aging, deformation or wear of the sealing strip during long-term use, can withstand a wider range of temperature changes, and maintains stable sealing effect under long-term vibration and impact conditions. It fully avoids the problem of water vapor evaporation and condensation on the transparent shell 22 to form fog after the tail lamp is turned on, ensures that the transparent shell 22 always remains clean and transparent, and thus maintains the best optical performance and service life of the tail lamp.

[0068] In addition, in the optional embodiment of the present embodiment, a part of the bottom shell assembly 100 inserted into the inside of the positioning groove 2101 is embedded in the hollow part 2102 and clamped with the boundary of the hollow part 2102. This design enhances the bonding force between the bottom shell assembly 100 and the positioning groove 2101, effectively avoiding the problem of loosening caused by external vibration or impact, thereby improving the structural reliability; and by embedding a part of the bottom shell assembly 100 in the hollow part 2102, the obstruction to the light propagation path is reduced, and the penetration of light when passing through the shell 200 is improved.

[0069] Referring to Figure 3 , Figure 7 and Figure 8 , in the optional embodiment of the present embodiment, the bottom shell assembly 100 includes a bottom shell 11, a modeling plate 12, and a light shielding plate 13. The bottom shell 11 has an installation cavity inside for mounting a light emitting assembly, and an installation opening on one side of the bottom shell 11 in communication with the installation cavity; the modeling plate 12 is arranged on the installation opening on one side of the bottom shell 11 and covers the outside of the light emitting assembly, and the modeling plate 12 has a light transmission part 121; the light shielding plate 13 is arranged on the side of the modeling plate 12 away from the installation cavity inside the bottom shell 11, and the light shielding plate 13 is positioned and connected with the bottom shell 11 through positioning structure one 3, and the light shielding plate 13 is also positioned and connected with the modeling plate 12 through positioning structure two 4, and the light shielding plate 13 has a light transmission part two 131 at least partially coinciding with the light transmission part one 121.

[0070] Specifically, the bottom shell 11 is configured as an open shell, and the shape and size of the modeling plate 12 and the shape and size of the light shielding plate 13 are adapted to the cross section and shape and size of the mounting cavity inside the bottom shell 11, so that the modeling plate 12 and the light shielding plate 13 can completely cover the mounting opening of the bottom shell 11. The modeling plate 12 can be configured as a flat plate, or can be recessed away from the bottom shell 11. When the modeling plate 12 is recessed away from the bottom shell 11, it can provide a space for the light emitting assembly. The light shielding plate 13 can be configured as a flat plate, or can be recessed away from the bottom shell 11. When the light shielding plate 13 is recessed away from the bottom shell 11, a groove is formed on the side facing the modeling plate 12, and the modeling plate 12 can be at least partially structured in the groove, so that the modeling plate 12 and the light shielding plate 13 are partially structured. Overlapping improves the compactness of the bottom shell assembly 100 structure. The light shielding plate 13 forms a protrusion on the side facing the connecting plate 21, and the cross-sectional shape and size of the protrusion are adapted to the cross-sectional shape and size of the positioning groove 2101.

[0071] The light shielding plate 13 is detachably connected to the bottom shell 11 through the positioning structure one 3, and is detachably connected to the modeling plate 12 through the positioning structure two 4. The modeling plate 12 and the light shielding plate 13 can be detached from the bottom shell 11 for replacement.

[0072] In this optional embodiment, the bottom shell assembly 100 not only includes the bottom shell 11, but also includes the modeling plate 12 and the light shielding plate 13. Through the cooperation of the modeling plate 12 and the light shielding plate 13, the design flexibility of the bottom shell assembly 100 is improved, thereby giving the tail lamp more design possibilities. For example, by changing the position and shape of the light transmission part one 121 on the modeling plate 12 and the layout of the light transmission part two 131 on the light shielding plate 13, different lighting effects and visual styles can be achieved, and the modeling diversity of the tail lamp is improved.

[0073] Furthermore, by designing the bottom shell assembly 100 as a modular structure including the bottom shell 11, the modeling plate 12 and the light shielding plate 13, the bottom shell 11 can be reused as a general part. This design can reduce the problem of part waste caused by model iteration and upgrading. Specifically, when new modeling requirements need to be met, only the modeling plate 12 and the light shielding plate 13 need to be replaced, without the need to redesign or produce the entire bottom shell assembly 100. This not only reduces the research and production cost of new parts, but also optimizes the inventory management efficiency and avoids the problem of large inventory and waste caused by model updates in the traditional one-piece design of the bottom shell assembly 100.

[0074] In addition, in the optional embodiment, the positioning structure one 3 realizes the positioning connection between the light shielding plate 13 and the bottom shell 11, and the positioning structure two 4 realizes the positioning connection between the light shielding plate 13 and the modeling plate 12. This double positioning mechanism ensures the assembly precision between the components, and enhances the stability and reliability of the overall structure. More importantly, this flexible assembly method allows the modeling plate 12 and the light shielding plate 13 of different shapes and specifications to be quickly combined with the same bottom shell 11, thereby adapting to various modeling needs and greatly improving the adaptability of the product. The design that the light transmission part one 121 on the modeling plate 12 and the light transmission part two 131 on the light shielding plate 13 at least partially overlap can ensure the light shielding effect while providing an accurate light output path. This design allows the light of the light emitting assembly to pass through the light transmission part one 121 and the light transmission part two 131 in the expected manner, forming an ideal lighting effect.

[0075] With reference to Figure 6 And Figures 9 to 13 In the optional embodiment of the present embodiment, the side surface of the connecting plate 21 away from the transparent shell 22 is provided with a limiting convex edge 211, the limiting convex edge 211 surrounds a positioning groove 2101, a limiting groove 5 is formed between the edge of the light shielding plate 13 and the edge of the bottom shell 11, the limiting convex edge 211 is inserted into the inside of the limiting groove 5, and the limiting convex edge 211 and the inner wall of the limiting groove 5 are in sealing connection. In the optional embodiment, the limiting groove 5 is formed between the edge of the light shielding plate 13 and the edge of the bottom shell 11, and the limiting convex edge 211 is inserted into the limiting groove 5, so that the connecting plate 21 is tightly fitted with the bottom shell 11 and the light shielding plate 13. This not only provides a physical fixing effect, but also effectively prevents the connecting plate 21 from loosening or shifting during use, ensuring the stability and reliability of the entire bottom shell assembly 100 under various use conditions, and facilitating quick positioning and assembly to improve production efficiency.

[0076] With reference to Figure 3 And Figures 7 to 13 In the optional embodiment of the present embodiment, the positioning structure one 3 includes a positioning column one 31 and a positioning hole one 32 that are inserted into each other; the inner side surface of the bottom shell 11 is provided with a lap convex platform 112, and one of the lap convex platform 112 and the edge part two of the light shielding plate 13 is provided with the positioning column one 31, and the other is provided with the positioning hole one 32. Specifically, the positioning structure one 3 can have one or more sets of positioning column one 31 and positioning hole one 32 matching structures. When there are multiple sets, optionally but not limitedly, such as Figure 3As shown, the plurality of positioning holes one 32 are arranged on the side surface of the overlap boss 112 inside the bottom shell 11 towards the side surface of the sun visor 13, and the plurality of positioning columns one 31 are arranged on the edge of the sun visor 13 and protrude towards the side surface of the bottom shell 11.
