Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a license plate mounting structure and a vehicle. Background Technology

[0002] With the rapid development of the automotive industry, consumers have placed higher demands on the personalization and refinement of vehicle exterior styling. As a key visual node in the vehicle's exterior, the license plate mounting area must not only meet functional requirements (such as license plate fixation and logo display) but also maintain harmony with the overall vehicle design. In recent years, to enhance the layering and three-dimensionality of vehicle styling, some models have tended to adopt a deeper license plate recess structure to create a more visually impactful exterior effect.

[0003] In related technologies, an integral plastic part is used as the main structure for license plate installation, while the body sheet metal is partially lowered to create a matching space, so that the integral plastic part and the lowered sheet metal structure can be directly combined, thereby achieving the design intention of a license plate recess with a greater depth.

[0004] However, the design of the license plate recess in the relevant technology will increase the vehicle's weight. Utility Model Content

[0005] In view of this, this application provides a license plate mounting structure and vehicle, which helps to solve the problem of increased vehicle weight caused by the deep license plate recess design in related technologies.

[0006] To achieve the above objectives, the technical solution of this application is implemented as follows:

[0007] On one hand, this application provides a license plate mounting structure, including: a sheet metal part having a through hole extending along its own thickness; a mounting bracket disposed on the side of the sheet metal part facing the vehicle interior, the mounting bracket defining a mounting groove with one open end, the mounting groove being opposite to the through hole; and a mounting trim panel fixed in the mounting groove, the mounting trim panel being recessed into the outer surface of the sheet metal part, the mounting trim panel being used for mounting a license plate.

[0008] The license plate mounting structure of this application utilizes a design that involves creating a through hole in the sheet metal part, establishing a mounting bracket that defines a mounting groove on the side of the sheet metal part facing the vehicle interior, and fixing the decorative panel into the mounting groove opposite the through hole, recessed within the outer surface of the sheet metal part. This design avoids the use of traditional integral plastic parts, effectively reducing vehicle weight. The mounting bracket is integrated into the inner side of the sheet metal part, maintaining the integrity of the sheet metal cavity structure and improving the structural rigidity of that area. Simultaneously, it eliminates the need for partial recessing of the sheet metal part, reducing encroachment on other spaces and improving space utilization. Furthermore, this design avoids the use of traditional integral plastic parts, thus reducing manufacturing costs.

[0009] In one possible implementation, the sheet metal part includes a first flange surrounding the through hole; the mounting bracket includes a base plate opposite to the through hole and a surrounding plate surrounding the mounting groove, the surrounding plate being located on the side of the first flange facing away from the mounting groove and being fixedly connected to the first flange.

[0010] Thus, the fixed connection design between the first flange of the sheet metal part and the mounting bracket enclosure effectively improves the reliability of the connection between the mounting bracket and the sheet metal part. The first flange surrounds the through hole, enhancing the local strength of the sheet metal part in the through hole area and preventing edge deformation. The enclosure is located on the side of the first flange facing away from the mounting groove and is fixed to it, increasing the contact area between the two. This allows the force on the mounting bracket to be evenly transferred to the sheet metal part through the enclosure, reducing local stress concentration and improving structural durability. At the same time, this connection method simplifies the assembly process and reduces manufacturing difficulty and cost.

[0011] In one possible implementation, the enclosure panel is fitted and welded to the first flange.

[0012] Thus, the design of the enclosure panel and the first flange fitting together and being welded significantly improves the connection strength and stability between the mounting bracket and the sheet metal parts. The close fit increases the contact area between the two, making the welding area more uniform, avoiding the risk of localized incomplete welds or detachment, and ensuring that the load on the mounting bracket is effectively transferred to the sheet metal parts through the weld surface, reducing stress concentration at the connection point. Furthermore, the weld's sealing prevents rainwater and dust from seeping in through the connection gaps, reducing the risk of internal structural corrosion and extending the service life of the license plate mounting structure.

[0013] In one possible implementation, the decorative panel includes: a mounting portion opposite to and connected to the base plate, the mounting portion being used to mount a license plate; and a connecting portion disposed around the mounting portion and connected to the enclosure panel.

[0014] Thus, the segmented design, where the mounting section connects to the base plate and the connecting section connects to the surrounding panel, effectively enhances the stability and structural reliability of the license plate installation. The mounting section, positioned opposite and directly connected to the base plate, provides precise positioning and stable support for the license plate, ensuring it remains securely in place. The connecting section surrounds the mounting section and connects to the surrounding panel, forming a ring-shaped support structure that evenly distributes the stress from the license plate installation to the surrounding panel and sheet metal components, preventing deformation or breakage caused by localized stress concentration. Furthermore, the circumferential connection structure helps maintain consistent gaps between the mounting section and the outer surface of the sheet metal, ensuring an aesthetically pleasing design that balances functionality and appearance.

[0015] In one possible implementation, the base plate is provided with multiple slots, and the mounting part is provided with multiple buckles on the side facing the base plate, the buckles engaging with the slots.

[0016] Thus, the snap-fit ​​design of the base plate latches and mounting clips significantly improves the assembly efficiency and connection reliability of the decorative panel and mounting bracket. The corresponding arrangement of multiple sets of latches and clips enables rapid positioning and tool-free assembly, greatly shortening assembly time and reducing labor costs. Furthermore, compared to bolts and welding, snap-fit ​​connections eliminate the need for additional fasteners, reducing structural weight and component costs, further enhancing the structure's practicality.

[0017] In one possible implementation, the mounting part is further provided with a plurality of first connection holes, and the license plate is provided with a plurality of second connection holes. The mounting part and the license plate are connected by fasteners passing through the first connection holes and the second connection holes.

[0018] Thus, the fastener connection design between the first connecting hole of the mounting unit and the second connecting hole of the license plate effectively improves the accuracy, stability, and ease of maintenance of the license plate installation. The corresponding arrangement of multiple first and second connecting holes ensures precise positioning of the license plate and the mounting unit, avoiding positional deviations caused by installation misalignment. The fastener's connection through the double holes provides high-strength mechanical locking force, ensuring that the license plate is not easily loosened or detached due to vibration during vehicle operation, thus improving reliability.

[0019] In one possible implementation, the enclosure includes a first top plate located at the top of the mounting groove, the connecting portion includes a second top plate located at the top of the mounting groove, the first top plate has a first mounting hole, the second top plate has a second mounting hole, and the license plate mounting structure further includes a license plate light, the license plate light is fixed at the second mounting hole, and a portion of the license plate light passes through the second mounting hole and the first mounting hole and is connected to the first top plate.

[0020] Thus, the alignment design of the dual mounting holes on the first and second top plates, along with the cross-layer connection structure of the license plate light, significantly improves the installation accuracy, stability, and functional reliability of the license plate light. The corresponding placement of the first and second mounting holes ensures precise positioning of the license plate light, avoiding illumination angle deviations or insufficient coverage caused by installation misalignment. The license plate light section passes through the dual holes and connects to the first top plate, forming a double-fixed support that effectively distributes the stress caused by vehicle vibrations, reducing the risk of loosening or detachment. Simultaneously, the elimination of the need for an additional license plate light mounting bracket reduces the number of parts and material costs, meeting the requirements for lightweight design and cost reduction.

[0021] In one possible implementation, the second top plate is provided with a mounting recess that is recessed toward the first top plate, and the second mounting hole is formed on the bottom wall of the mounting recess. The license plate light includes a light plate and a fixing structure. The light plate is fixed in the mounting recess, and the fixing structure passes through the second mounting hole and the first mounting hole in sequence.

[0022] Thus, the design of the mounting recess on the second top plate to fit the license plate light panel, combined with the double-hole connection of the fixing structure, provides precise positioning space for the light panel. This ensures that the light panel is flush with or slightly protruding from the outer surface of the second top plate after installation, avoiding lighting angle deviations or unsightly appearances caused by positional misalignment, thereby improving functional reliability and aesthetic appeal. The double fixing mechanism, which passes through the second mounting hole and the first mounting hole sequentially and connects to the first top plate, further enhances the installation stability of the light panel and reduces the probability of detachment.

[0023] In one possible implementation, the sheet metal part further includes: a sheet metal body, the through hole penetrating the sheet metal body, the mounting bracket including a second flange located at one end of the enclosure opposite to the bottom plate, the second flange forming an assembly gap with the sheet metal body, and the license plate mounting structure further including: shock-absorbing adhesive, the shock-absorbing adhesive filling the assembly gap.

[0024] Thus, by filling the assembly gap between the second flange and the sheet metal body with damping adhesive, the impact energy generated by vibration or bumps during vehicle operation can be effectively absorbed, reducing rigid collisions between the mounting bracket and the sheet metal body, lowering the probability of abnormal noises, and improving the user experience. The filled damping adhesive also forms a sealing barrier, preventing rainwater and dust from seeping into the interior through the assembly gap, avoiding corrosion and aging of the mounting bracket or sheet metal parts, and extending the structural lifespan. Furthermore, the compressibility of the damping adhesive can compensate for manufacturing or assembly tolerances between the sheet metal body and the mounting bracket, ensuring a good fit between the second flange and the sheet metal body and improving connection stability.

[0025] On the other hand, this application also provides a vehicle, including: a body; a license plate mounting structure as described in any of the above possible implementations, wherein the sheet metal of the license plate mounting structure is connected to the body.

[0026] The vehicle of this utility model, by using the aforementioned license plate mounting structure, avoids the use of integral plastic parts, achieving a lightweight design, reducing the overall vehicle weight, and contributing to improved fuel economy or extended range for electric vehicles. The mounting bracket is integrated into the inner side of the sheet metal part, maintaining the integrity of the sheet metal cavity structure and improving the structural rigidity of that area. Simultaneously, it eliminates the need for partial sagging of the sheet metal part, reducing encroachment on other spaces and improving space utilization. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0045] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0046] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0047] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0049] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0050] In recent years, to enhance the layering and three-dimensionality of vehicle styling, some models have tended to adopt a deeper license plate recess structure to create a more visually impactful exterior effect. In related technologies, a single-piece plastic component serves as the main structure for the license plate mounting, while a portion of the body sheet metal is lowered to create a matching space. This allows the single-piece plastic component to directly integrate with the lowered sheet metal structure, thus achieving the desired deep license plate recess design. However, the design of the license plate recess in these technologies increases the vehicle's weight.

[0051] In view of this, the present application provides a license plate mounting structure and vehicle. This structure, which involves creating a through hole in a sheet metal part and providing a mounting bracket defining a mounting groove on the side of the sheet metal part facing inwards, fixes the decorative panel within the mounting groove opposite the through hole and recessed into the outer surface of the sheet metal part. This design avoids the use of traditional integral plastic parts, effectively reducing vehicle weight. Furthermore, the above design, by avoiding the use of traditional integral plastic parts, can also reduce manufacturing costs.

[0052] It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, a bus, a truck, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. For instance, the vehicle can be any one of electric vehicles / electric cars, pure electric vehicles, hybrid electric vehicles, range-extended electric vehicles, plug-in hybrid electric vehicles, and new energy vehicles.

[0053] Vehicles typically consist of wheels, a power source, and a transmission system between the wheels and the power source. The transmission system transmits the power provided by the power source to the wheels, causing them to rotate and thus driving the vehicle.

[0054] It should be noted that the type of power source of the vehicle is not limited in the embodiments of this application. For example, for fuel vehicles, the power source can refer to fuel engines such as gasoline engines and diesel engines; for electric vehicles, the power source can refer to electric motors; for hybrid vehicles, the power source can refer to engines or electric motors; for vehicles powered by other means, the power source can refer to devices that generate power.

[0055] The vehicle may also include a chassis and a body mounted on the chassis. The body may have a passenger compartment, which may include a driver's seat, passenger seats, etc., where the driver can operate the vehicle. For example, the vehicle body may also include structural components such as a steering wheel, clutch, and brakes to enable the vehicle to perform its full functions; this application does not impose any limitations on these components.

[0056] It is understandable that license plates must be installed at both the front and rear of a vehicle to meet relevant requirements. Furthermore, the front and rear license plate installation areas are important visual nodes on the vehicle's exterior, requiring a balance between functional and aesthetic needs. The license plate installation structure described in this application is applicable to both front and rear license plate installation scenarios. The technical solution presented in this application can flexibly adapt to the installation requirements of both front and rear license plates, possessing both versatility and technological advantages.

[0057] In the following embodiments, the installation scenario of the rear license plate is used as an example for illustration.

[0058] The following is for reference. Figures 1-4 This application provides a license plate mounting structure 1, including a sheet metal part 10, a mounting bracket 20, and a decorative panel 30. The sheet metal part 10 serves as a basic load-bearing structure, providing rigid support and mounting space for the license plate. The sheet metal part 10 has a through hole 11. Specifically, the through hole 11 can penetrate the sheet metal part 10 along its thickness direction.

[0059] The mounting bracket 20 serves as an intermediate structure connecting the sheet metal part 10 and the decorative panel 30, primarily providing support, positioning, and enhancing structural rigidity. The mounting bracket 20 is located on one side of the sheet metal part 10. Specifically, the mounting bracket 20 can be located on the side of the sheet metal part 10 facing the interior of the vehicle. The mounting bracket 20 also includes a mounting groove 21. One end of the mounting groove 21 is open and aligns with the through hole 11. The decorative panel 30 can be fixedly installed within the mounting groove 21. The decorative panel 30 can be recessed into the outer surface of the sheet metal part 10. The decorative panel 30 is used for mounting the license plate.

[0060] Understandably, the structural design of opening a through hole 11 in the sheet metal part 10, setting a mounting bracket 20 that defines a mounting groove 21 on the side of the sheet metal part 10 facing the vehicle interior, and fixing the decorative panel 30 into the mounting groove 21 opposite to the through hole 11 and recessed into the outer surface of the sheet metal part 10, avoids the use of traditional integral plastic parts, effectively reducing the vehicle's weight. The mounting bracket 20 is integrated into the inner side of the sheet metal part 10, maintaining the integrity of the sheet metal cavity structure and improving the structural rigidity of this area. At the same time, it eliminates the need for partial recessing of the sheet metal part 10, reducing encroachment on other spaces and improving space utilization. In addition, the above design avoids the use of traditional integral plastic parts, which can also reduce manufacturing costs.

[0061] In one possible implementation, refer to Figure 1 , Figure 2The sheet metal part 10 includes a first flange 12. The first flange 12 can surround the through hole 11. Further, the mounting bracket 20 includes a base plate 22 and a surrounding plate 23. The base plate 22 of the mounting bracket 20 can be disposed opposite to the through hole 11. The surrounding plate 23 of the mounting bracket 20 can surround the mounting groove 21. The surrounding plate 23 can be located on one side of the first flange 12. Specifically, the surrounding plate 23 can be located on the side of the first flange 12 facing away from the mounting groove 21. Furthermore, the surrounding plate 23 can be fixedly connected to the first flange 12.

[0062] Optionally, the base plate 22 can be a flat plate structure, and it is opposite to the through hole 11 of the sheet metal part 10. Its size is slightly smaller than the through hole 11, ensuring that the mounting plate 30 can be exposed on the surface of the sheet metal part 10 through the through hole 11. The mounting bracket 20 can be formed from DC07 ultra-deep drawing steel sheet. DC07 ultra-deep drawing steel sheet has excellent deep drawing performance and can reliably form a mounting groove 21 structure with a large depth to meet the shaping requirements of a deeper license plate recess. The mounting plate 30 can be a plastic part, preferably made of PC-PET composite material. PC-PET composite material is an alloy material formed by blending polycarbonate and polyethylene terephthalate. PC-PET composite material has a low coefficient of thermal expansion and good dimensional stability at high and low temperatures, which can effectively avoid the warping or expansion and contraction of the edge of the mounting plate 30 caused by changes in ambient temperature, thereby ensuring the consistency and uniformity of the matching between the mounting plate 30 and the sheet metal part 10, taking into account both aesthetic appearance and functional reliability.

[0063] Understandably, the fixed connection design between the first flange 12 of the sheet metal part 10 and the surrounding plate 23 of the mounting bracket 20 effectively improves the connection reliability between the mounting bracket 20 and the sheet metal part 10. The first flange 12 surrounds the through hole 11, enhancing the local strength of the sheet metal part 10 in the area of ​​the through hole 11 and preventing edge deformation. The surrounding plate 23 is located on the side of the first flange 12 facing away from the mounting groove 21 and is fixed thereto, expanding the contact area between the two. This allows the force on the mounting bracket 20 to be evenly transmitted to the sheet metal part 10 through the surrounding plate 23, reducing local stress concentration and improving structural durability. At the same time, this connection method simplifies the assembly process and reduces manufacturing difficulty and cost.

[0064] In one possible implementation, the enclosure 23 can be fitted together with the first flange 12. Furthermore, to achieve a tight connection and improve connection stability, the enclosure 23 and the first flange 12 can be welded together. For example, the enclosure 23 and the first flange 12 can be connected by processes such as spot welding, laser brazing, or laser fly welding.

[0065] Understandably, the design of the enclosure 23 and the first flange 12 being fitted together and welded significantly improves the connection strength and stability between the mounting bracket 20 and the sheet metal part 10. The fitted design increases the contact area between the two, making the welding area more uniform, avoiding the risk of localized incomplete welds or detachment, and ensuring that the force on the mounting bracket 20 can be effectively transferred to the sheet metal part 10 through the welding surface, reducing stress concentration at the connection point. Furthermore, the sealing effect of the weld prevents rainwater, dust, etc., from seeping in through the connection gap, reducing the risk of internal structural corrosion and extending the service life of the license plate mounting structure 1.

[0066] In one possible implementation, refer to Figure 3 , Figure 4 , Figure 5 The decorative panel 30 includes a mounting part 31 and a connecting part 32. The mounting part 31 can be opposite to and connected to the base plate 22. The mounting part 31 and the base plate 22 can be connected by means of snap-fit ​​311, bolt fixing, or other methods. The mounting part 31 can be used to install a license plate. The connecting part 32 can be located around the mounting part 31. The connecting part 32 can be connected to the surrounding panel 23.

[0067] Understandably, the segmented design, where the mounting portion 31 of the decorative panel 30 connects to the base plate 22 and the connecting portion 32 connects to the surrounding panel 23, effectively enhances the stability and structural reliability of the license plate installation. The mounting portion 31 is positioned opposite to and directly connected to the base plate 22, providing precise installation positioning and stable support for the license plate, ensuring it is not easily loosened after fixing. The connecting portion 32 surrounds the mounting portion 31 and connects to the surrounding panel 23, forming a ring-shaped support structure. This evenly distributes the stress from the license plate installation to the surrounding panel 23 and the sheet metal part 10, preventing deformation or breakage caused by localized stress concentration. Furthermore, the circumferential connection structure helps maintain consistent gaps between the decorative panel 30 and the outer surface of the sheet metal part 10, ensuring an aesthetically pleasing design that balances functional and aesthetic requirements.

[0068] In one possible implementation, refer to Figure 3 , Figure 4 , Figure 7 The base plate 22 may be provided with multiple slots 221. The mounting part 31 facing the base plate 22 may also be provided with multiple buckles 311. The buckles 311 and the slots 221 can be engaged. In this way, the multiple slots 221 on the base plate 22 and the multiple buckles 311 on the mounting part 31 can form multiple sets of connection structures to realize the connection between the mounting bracket 20 and the decorative panel 30.

[0069] Understandably, the snap-fit ​​design between the base plate 22's latch 221 and the mounting part 31's buckle 311 significantly improves the assembly efficiency and connection reliability of the decorative panel 30 and the mounting bracket 20. The corresponding arrangement of multiple sets of latches 221 and buckles 311 enables rapid positioning and tool-free assembly, greatly shortening assembly time and reducing labor costs. Furthermore, compared to bolts and welding, snap-fit ​​connections eliminate the need for additional fasteners, reducing structural weight and component costs, further enhancing the structure's practicality.

[0070] In one possible implementation, refer to Figure 4 , Figure 8 The mounting part 31 is also provided with a plurality of first connecting holes 312. Correspondingly, the license plate is provided with a plurality of second connecting holes. In this way, the mounting part 31 and the license plate can be connected by fasteners passing through the first connecting holes 312 and the second connecting holes. Optionally, the fasteners can be a combination of stainless steel self-tapping screws or aluminum alloy bolts and elastic washers. In addition, anaerobic adhesive can be coated on the thread surface, and the additional locking force can be formed by the curing of the adhesive layer to ensure that the fasteners do not loosen during long-term use. The number and position of the first connecting holes 312 and the second connecting holes can be determined according to actual needs, and this application does not impose any restrictions.

[0071] Understandably, the fastener connection design between the first connecting hole 312 of the mounting part 31 and the second connecting hole of the license plate effectively improves the accuracy, stability, and ease of maintenance of the license plate installation. The corresponding arrangement of multiple first connecting holes 312 and second connecting holes achieves precise positioning of the license plate and the mounting part 31, avoiding positional deviations caused by installation misalignment. The fastener's connection through the double holes provides high-strength mechanical locking force, ensuring that the license plate is not easily loosened or detached due to vibration during vehicle operation, thus improving reliability.

[0072] In one possible implementation, refer to Figure 8 The enclosure 23 includes a first top plate 231. The first top plate 231 can be located at the top of the mounting groove 21. The connecting portion 32 of the mounting trim 30 includes a second top plate 321. The second top plate 321 can be located at the top of the mounting groove 21. In this way, the first top plate 231 and the second top plate 321 can be arranged opposite to each other. And, the first top plate 231 is located above the second top plate 321.

[0073] Furthermore, a first mounting hole 232 is provided on the first top plate 231. A second mounting hole 322 is provided on the second top plate 321. The license plate light 40 can be installed through the first mounting hole 232 and the second mounting hole 322. Specifically, the license plate mounting structure 1 also includes the license plate light 40. The license plate light 40 can be fixed at the second mounting hole 322. Moreover, part of the structure of the license plate light 40 can pass through the second mounting hole 322 and the first mounting hole 232 to connect with the first top plate 231.

[0074] Understandably, the alignment design of the dual mounting holes on the first top plate 231 and the second top plate 321, along with the cross-layer connection structure of the license plate light 40, significantly improves the installation accuracy, stability, and functional reliability of the license plate light 40. The corresponding arrangement of the first mounting hole 232 and the second mounting hole 322 ensures precise positioning of the license plate light 40, avoiding illumination angle deviations or insufficient coverage caused by installation misalignment. Part of the license plate light 40 structure passes through the dual holes and connects to the first top plate 231, forming a double-fixed support that effectively disperses the force caused by vehicle vibrations, reducing the risk of loosening or detachment. Simultaneously, the elimination of the need for an additional mounting bracket for the license plate light 40 reduces the number of parts and material costs, meeting the requirements for lightweighting and cost reduction.

[0075] In one possible implementation, refer to Figure 8 The second top plate 321 is provided with a mounting recess 323. The mounting recess 323 can be recessed towards the first top plate 231. The second mounting hole 322 can be formed on the bottom wall of the mounting recess 323. Further, the license plate light 40 can include a light plate 41 and a fixing structure 42. The light plate 41 can be fixed in the mounting recess 323. In this way, the outer surface of the light plate 41 can be flush with the outer surface of the second top plate 321. And, when the light plate 41 is embedded in the mounting recess 323, the side wall of the mounting recess 323 will contact the edge of the light plate 41, forming a vertical limit to prevent the light plate 41 from moving up and down. At this time, the fixing structure 42 can be a fixing post. The fixing structure 42 can be engaged with the first mounting hole 232.

[0076] Furthermore, the fixing structure 42 can pass through the second mounting hole 322 and the first mounting hole 232 in sequence. The fixing structure 42 can also be an elastic locking part, an elastic locking foot, a spring sheet, etc. After passing through the first mounting hole 232, the fixing structure 42 can form a locking or elastic abutment with the back side of the first top plate 231 (i.e., the side of the first top plate 231 facing the vehicle interior), thereby limiting the vertical position of the lamp panel 41. Specifically, the fixing structure 42 can be designed as an elastic locking foot with a barbed protrusion at its end. When the fixing structure 42 passes through the second mounting hole 322 and the first mounting hole 232 in sequence, the elastic locking foot undergoes elastic deformation due to compression, allowing the barbed protrusion to pass smoothly through the first mounting hole 232. After completely passing through the hole, the elastic locking foot returns to its original shape, and the barbed protrusion abuts tightly against the surface of the back side of the first top plate 231.

[0077] Understandably, the design of the mounting recess 323 on the second top plate 321 and the lamp plate 41 of the license plate light 40, combined with the double-hole connection of the fixing structure 42, provides precise positioning space for the lamp plate 41. This ensures that the lamp plate 41 is flush with or slightly convex to the outer surface of the second top plate 321 after installation, avoiding lighting angle deviations or unsightly appearances caused by positional offsets, thus improving functional reliability and aesthetic appeal. The double fixing of the fixing structure 42, which passes through the second mounting hole 322 and the first mounting hole 232 and connects to the first top plate 231, further enhances the installation stability of the lamp plate 41 and reduces the probability of detachment.

[0078] In one possible implementation, refer to Figures 5-10 The sheet metal part 10 also includes a sheet metal body 13. A through hole 11 can penetrate the sheet metal body 13. The mounting bracket 20 may also include a second flange 24. The second flange 24 can be located at one end of the enclosure 23. Specifically, the second flange 24 can be located at the end of the enclosure 23 opposite to the base plate 22. An assembly gap can be formed between the second flange 24 and the sheet metal body 13. The license plate mounting structure 1 also includes shock-absorbing rubber 50. The shock-absorbing rubber 50 can fill the assembly gap. The shock-absorbing rubber 50 can be made of rubber or silicone.

[0079] Understandably, the design of filling the assembly gap between the second flange 24 and the sheet metal body 13 with damping adhesive 50 effectively absorbs the impact energy generated by vibration or bumps during vehicle operation, reduces rigid collisions between the mounting bracket 20 and the sheet metal body 13, lowers the probability of abnormal noises, and improves the user experience. The filled damping adhesive 50 also forms a sealing barrier, preventing rainwater, dust, etc., from seeping into the interior through the assembly gap, avoiding corrosion and aging of the mounting bracket 20 or sheet metal parts 10, and extending the service life of the structure. Furthermore, the compressibility of the damping adhesive 50 can compensate for manufacturing or assembly tolerances between the sheet metal body 13 and the mounting bracket 20, ensuring the fit between the second flange 24 and the sheet metal body 13 and improving connection stability.

[0080] In addition, the matching area between the decorative panel 30 and the sheet metal part 10 can be further optimized to improve the appearance quality. The outer area where the rounded corners of the decorative panel 30 and the sheet metal part 10 are matched can adopt a large rounded corner design with a gradual transition. The smooth curved surface connection reduces the visual abruptness and enhances the refinement and perceived quality of the exterior.

[0081] In the actual implementation process, the following two implementation methods can be selected according to the design requirements:

[0082] License plate mounting panel-less solution: If the license plate mounting panel 30 is not needed (e.g., the license plate recess area is the same color as the body and no additional decoration is required), the license plate mounting panel 30 can be omitted. The license plate mounting structure 1 can be formed directly by combining the sheet metal part 10 and the mounting bracket 20. In this case, the mounting bracket 20 is fixed by welding to the first flange 12 of the sheet metal part 10, which can not only meet the shape requirements of a deeper license plate recess, but also further reduce the number of parts, reduce manufacturing costs, and reduce the weight of the vehicle body.

[0083] Installation of decorative panels: If a decorative effect is required to highlight the license plate recess area (such as high-gloss black or other two-tone requirements), then decorative panel 30 can be retained, specifically divided into two sub-options:

[0084] (1) The license plate recess area of ​​the sheet metal part 10 can be masked and sprayed (such as high gloss black) to achieve a decorative effect through a single color matching process.

[0085] (2) Add a decorative panel 30, which is fixed to the mounting bracket 20 by front and rear snap-fit ​​or bolt connection. In order to control the matching gap between the decorative panel 30 and the sheet metal part 10, felt strips or foam pads can be set around the decorative panel 30, or limiting ribs can be set at the connection part 32. The uniformity of the gap and the consistency of the surface difference are ensured by elastic buffering or rigid limiting, taking into account both the aesthetic appearance and the reliability of assembly.

[0086] On the other hand, this application also provides a vehicle, including a body and the aforementioned license plate mounting structure 1. The sheet metal part 10 of the license plate mounting structure 1 can be connected to the body.

[0087] Understandably, the vehicle in this application, by using the aforementioned license plate mounting structure 1, avoids the use of integral plastic parts, achieving a lightweight design, reducing the overall vehicle weight, and contributing to improved fuel economy or enhanced range performance of electric vehicles. The mounting bracket 20 is integrated into the inner side of the sheet metal part 10, maintaining the integrity of the sheet metal cavity structure and improving the structural rigidity of that area. Simultaneously, it eliminates the need for partial sagging of the sheet metal part 10, reducing encroachment on other spaces and improving space utilization.

[0088] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on 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.
