Description
Technical Field
[0001] This invention relates to the field of automotive body parts, specifically to a lap-type exhaust tip structure and a lower trim panel assembly having the exhaust tip structure. Background Technology
[0002] With the continuous development of the automotive industry, the requirements for the integration of automotive exterior design and functional components are becoming increasingly stringent.
[0003] Exhaust tip trim has become an important component for enhancing the visual appeal of a vehicle's rear.
[0004] Traditional tailpipe decoration solutions have the following main technical limitations:
[0005] 1. Traditional tailpipe structures are usually inserted into the lower trim panel and then connected with clips, which results in insufficient longitudinal support of the tailpipe structure.
[0006] 2. Poor consistency in assembly with related components; Traditional tail throat structures are generally connected to related components by bolts or screws, resulting in large gaps at the connection points. In addition, the assembly time for bolted connections is relatively long, which is not conducive to the assembly and installation of the tail throat structure.
[0007] 3. Due to its inherent structural limitations, the traditional tailpipe structure has insufficient drainage performance: water and scale easily accumulate in the cavity after long-term use.
[0008] 4. Weak structural strength: Traditional tailpipe structures are generally just injection-molded parts, lacking internal reinforcement design, and are prone to deformation under the impact of high-pressure water during car washing or on bumpy roads.
[0009] 5. For lower trim panels with traditional tailpipe structures, holes need to be pre-drilled during injection molding because of the tailpipe structure. However, since the overall size of the lower trim panel is not large, there is often less material below the pre-drilled holes. This can easily lead to insufficient strength in the local area below the pre-drilled holes, especially during demolding, which can easily cause breakage and affect the production quality of the lower trim panel.
[0010] The existing patent 201921794995.8 - a tailpipe decorative part - does not clearly disclose the technical content that solves the above-mentioned technical problem.
[0011] Therefore, in order to improve or solve at least one of the above technical problems, it is necessary to optimize the design of the existing rear protection structure. Utility Model Content

[0070] In this utility model, the decorative box 111 includes an inner bottom plate 1111: the inner bottom plate 1111 is located on the inner side of the decorative box 111.
[0071] The inner bottom plate 1111 provides support and structural foundation to ensure the overall strength and stability of the decorative box 111. In actual arrangement, the decorative box 111 is arranged horizontally. In order to facilitate subsequent drainage, the opening of the decorative box 111 is generally required to be arranged downwards. This makes the inner bottom plate 1111 equivalent to being arranged at an angle to the horizontal plane.
[0072] The inner floor has a side plate 1112 at its edge. The side plate 1112 is a ring plate that surrounds the periphery of the inner bottom plate 1111.
[0073] The side panels 1112 and the inner bottom panel 1111 together form a box structure with an opening at one end, which serves both a protective and decorative function.
[0074] The side plate 1112 is generally a ring-shaped plate structure.
[0075] The inner bottom plate 1111 and the side plate 1112 together form a box structure with an opening at one end, which is usually designed to match the shape of the rear of the car.
[0076] In this utility model, the inner wall of the decorative box 111 is provided with a rib component; the rib component includes a plurality of individual ribs 1113 disposed in the decorative box 111; in this utility model, the rib component is disposed on the inner wall of the decorative box 111.
[0077] Rib components enhance the structural strength of the decorative box 111, preventing deformation or damage during use.
[0078] Multiple individual ribs 1113 are evenly distributed on the inner wall of the decorative box 111.
[0079] Each individual rib 1113 serves to support and reinforce, collectively enhancing the overall strength of the decorative box 111; each individual rib 1113 serves to support and reinforce, collectively enhancing the overall strength of the decorative box 111 and preventing deformation or damage during use; in addition, adjacent individual ribs 1113 are distributed at intervals; the interval grooves between adjacent individual ribs 1113 facilitate a good flow guiding effect, making it easy for the water entering the decorative box 111 to drain out.
[0080] Furthermore, in this utility model, the inner bottom plate 1111 is inclined; the angle between the inner bottom plate 1111 and the horizontal plane is acute; the vertical cross-section of the decorative box 111 is trapezoidal; the decorative box 111 has a decorative inner cavity; the minimum distance from the end of the decorative inner cavity near the inner bottom plate 1111 to the horizontal plane is greater than the minimum distance from the end of the decorative inner cavity away from the inner bottom plate 1111 to the horizontal plane; based on the above design, it can be seen that the decorative box 111 of this utility model has a structure with a small internal opening and a large external opening. This setting facilitates the actual demolding operation. At the same time, the decorative box 111 is similar to a trumpet-shaped structure, which facilitates the drainage of water inside the decorative box 111 during subsequent car washing.
[0081] Similarly, the inclined inner low plate can also achieve better drainage and reduce the accumulation of debris in the tailpipe structure 1.
[0082] In this utility model, the inner bottom plate 1111 is inclined; the inner bottom plate 1111 forms an acute angle with the horizontal plane; the inclined setting helps to optimize the internal space layout, enhance the stability and aesthetics of the structure; and at the same time facilitates slag discharge and drainage when tilted.
[0083] In this utility model, the vertical cross-section of the decorative box 111 is trapezoidal, narrow at the top and wide at the bottom; the trapezoidal structure enhances the overall stability of the decorative box 111.
[0084] The minimum distance from the inner cavity of the decorative box to the horizontal plane at the end closest to the inner bottom plate 1111 is greater than the minimum distance from the inner cavity of the decorative box to the horizontal plane at the end furthest from the inner bottom plate 1111. This design optimizes the utilization of internal space and enhances the overall visual effect, making the decorative box 111 more layered in appearance.
[0085] The decorative box 111 resembles a trumpet-shaped structure with a small internal opening and a large external opening; this structural design facilitates actual demolding operations and also offers several advantages in subsequent use.
[0086] The inner bottom plate 1111 is inclined: The inclined setting of the inner bottom plate 1111 helps the water to flow towards the external opening under the action of gravity, thereby achieving better drainage effect.
[0087] The trumpet-shaped design makes it easier for water to drain out through the external opening after entering the interior cavity, preventing water accumulation.
[0088] Inclined inner bottom plate 1111: The inclined design of the inner bottom plate 1111 not only helps with drainage, but also reduces the accumulation of debris in the tailpipe structure 1, keeping the interior clean.
[0089] The trapezoidal internal space design makes it easier for debris to slide outwards and be cleaned.
[0090] Furthermore, in this utility model, the tailpipe bright strip 12 has an overlapping connecting plate 122 on its main body. One end of the overlapping connecting plate 122 is connected to the bright strip body, and the other end overlaps with the trim panel body 21. Based on this design, the tailpipe bright strip 12 is not only connected to the tailpipe trim 11, but also connected to the trim panel body 21, which better ensures the accuracy and stability of the tailpipe structure 1 in the lower trim panel 2.
[0091] In this utility model, the trim flange 112 of the tailpipe trim 11 is pressed onto the overlapping connecting plate 122; at least one trim flange 112, overlapping connecting plate 122 and trim body 21 are connected by fasteners; based on this arrangement, a single fastener can achieve the common connection of the trim flange 112, overlapping connecting plate 122 and trim body 21, which ensures the stability of the tailpipe structure 1 on the lower trim 2 while reducing the use of fasteners.
[0092] By using the overlapping connecting plate 122, the contact area between the tailpipe bright strip 12 and the trim panel body 21 is increased, thereby improving the stability and reliability of the connection.
[0093] The overlapping plate 122 can distribute the stress on the tailpipe trim 12 to the trim body 21, avoiding damage caused by stress concentration.
[0094] The tailpipe trim 11 has a trim flange 112, which is pressed onto the overlapping connecting plate 122. The trim flange 112 pressing onto the overlapping connecting plate 122 further enhances the connection strength between the tailpipe bright strip 12 and the trim body 21.
[0095] The pressing action of the trim flange 112 can effectively prevent the tailpipe trim 12 from loosening or falling off during use.
[0096] Fasteners (such as screws, bolts, etc.) can securely connect the trim flange 112, the overlapping connecting plate 122 and the trim body 21 together, ensuring the connection strength between the tailpipe bright strip 12 and the trim body 21.
[0097] The use of fasteners makes the connection between the exhaust tip trim 12 and the trim panel body 21 easy to disassemble and maintain, facilitating subsequent replacement or repair.
[0098] This utility model uses multiple connection methods, including the overlapping connecting plate 122, the decorative flange 112, and fasteners, to make the connection between the tailpipe bright strip 12 and the decorative panel body 21 more stable and effectively prevent loosening or falling off.
[0099] Obviously, the specific implementation of this utility model is not limited to the above-mentioned methods. Any non-substantial improvements made using the inventive concept and technical solution of this utility model are within the protection scope of this utility model.
