Description

Technical Field

[0001] This utility model relates to the field of automotive technology, specifically to a vehicle front decoration system and a vehicle. Background Technology

[0002] The upper front section of existing vehicles is typically a sheet metal hood. Due to the complexity of the manufacturing process and high limitations, it is difficult to achieve personalized styling elements. Furthermore, the high strength of the metal results in poor energy absorption and inadequate pedestrian protection. In addition, to enhance personalized design, existing technologies incorporate front trim pieces, which are usually integrated with the bumper assembly. This requires improving the overall aesthetics of the vehicle while also meeting pedestrian protection requirements. However, due to the emphasis on pedestrian protection regulations, front trim systems often enhance energy absorption by adding cavities to the bumper, but this leads to insufficient strength and lower design reliability compared to vehicles without front trim pieces. Moreover, the integration of trim pieces into the front bumper increases wind resistance during driving, resulting in poor aerodynamic performance and lower fuel or electric power economy. Therefore, existing vehicles cannot simultaneously achieve pedestrian protection, structural strength, and aerodynamic performance. Utility Model Content

[0003] One objective of this utility model is to provide a vehicle front decoration system to solve the problem that existing vehicles cannot simultaneously achieve pedestrian protection, structural strength, and aerodynamic performance; the second objective is to provide a vehicle.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A vehicle front trim system includes: a front hood; a bumper having a first surface disposed on the front side of the front hood, the first surface being inclined relative to a horizontal plane, the first surface having a first side away from the front hood and a second side near the front hood, the first side being lower than the second side; a trim member covering at least a portion of the first surface, the trim member having a plate portion spaced apart from the first surface, a cavity forming between the plate portion and at least a portion of the first surface; an air inlet forming on the side of the cavity away from the front hood, and an air outlet forming on the side of the cavity near the front hood.

[0006] According to the aforementioned technical means, by setting a decorative element to cover at least a portion of the bumper, and with the panel of the decorative element spaced apart from the first surface of the bumper, the panel is suspended above the bumper, forming a cavity between the panel and the bumper. When a pedestrian collides with the decorative element, the cavity provides sufficient crumple space for the decorative element. Compared with traditional vehicles without decorative elements, the cavity design significantly enhances the energy absorption effect and effectively improves pedestrian protection. Furthermore, since the decorative element is added separately to the bumper and not integrated with it, it does not weaken the structural strength of either the decorative element or the bumper. At the same time, the cavity has openings on both the front and rear sides, and the first surface is inclined with a lower front and higher rear. During vehicle operation, the cavity acts as an airflow channel, guiding airflow from the front of the vehicle to the upper side of the front cover, reducing aerodynamic drag and significantly lowering the drag coefficient. This effectively improves aerodynamic performance, significantly optimizing vehicle economy, making it more efficient and energy-saving. Moreover, as the airflow passes through the cavity, it exerts downward pressure on the bumper, increasing the vehicle's grip and thus improving safety and handling.

[0007] Furthermore, the plate portion includes a first plate body, a second plate body, and a boss. The first plate body and the second plate body are arranged at a distance from each other. The second plate body is arranged at a distance from the first surface. The first plate body is located on the side of the second plate body away from the first surface. The boss is connected between the first plate body and the second plate body.

[0008] According to the above technical means, by setting the plate part to include two layers of plate bodies arranged in layers along its thickness direction, and the two layers of plate bodies are connected by a boss support, on the one hand, the structural strength of the plate part is guaranteed, and on the other hand, the gap between the two layers of plate bodies can also serve as a buffer space, which can improve the energy absorption effect of the plate part itself, thereby further strengthening the pedestrian protection function.

[0009] Furthermore, the boss has a hollow structure;

[0010] And / or, at least one end of the boss is bonded to the first plate or the second plate.

[0011] Based on the above technical means, the hollow structure boss can collapse and deform when a vehicle collides with a pedestrian, absorb some of the impact energy, reduce the impact force on the pedestrian's head, and further improve the pedestrian protection performance of the decorative parts.

[0012] Bonding is a low-cost and simple method. Compared to traditional welding, it avoids appearance defects such as weld marks and can also prevent weld marks from harming pedestrians, thus improving pedestrian protection performance.

[0013] Furthermore, at least one support column is provided on the side of the second plate facing the first surface, and the support column is supported between the second plate and the first surface.

[0014] According to the above technical means, by setting support columns on the second plate and supporting the second plate on the first surface through the support columns, the structural strength of the decorative part is ensured, the reliability of the connection between the decorative part and the bumper is enhanced, and the support columns can divide the cavity, thereby reducing air turbulence and optimizing aerodynamic performance.

[0015] Furthermore, the second plate is provided with a first snap-fit ​​portion, and the bumper is provided with a second snap-fit ​​portion corresponding to the first snap-fit ​​portion, and the first snap-fit ​​portion snaps into the second snap-fit ​​portion.

[0016] According to the above technical means, by setting the first snap-fit ​​part of the second plate to snap-fit ​​part on the bumper, a stable connection between the second plate and the bumper is achieved, thereby realizing a stable connection of the decorative parts on the bumper. The snap-fit ​​structure is relatively simple, the cost is low, and the connection is stable and highly reliable.

[0017] Furthermore, the first latching portion includes a metal buckle, and the second latching portion includes a first latching hole, wherein the metal buckle engages with the first latching hole; and / or,

[0018] The first snap-fit ​​portion includes an injection-molded snap-fit ​​claw, and the second snap-fit ​​portion includes a second snap-fit ​​hole, wherein the injection-molded snap-fit ​​claw engages with the second snap-fit ​​hole.

[0019] Based on the above technical means, the structure of the buckle and the buckle hole is relatively simple and easy to process. Moreover, the metal buckle has good rigidity and toughness, and the connection strength is high, ensuring that reliable connection performance can be maintained under normal working conditions.

[0020] The claws can be inserted into the second locking hole to achieve a locking engagement. The structure is simple and easy to assemble. In addition, the injection-molded claws have a certain elastic deformation capability, which can absorb some energy when a vehicle collides, preventing the decorative parts from falling off the bumper and further improving pedestrian protection performance.

[0021] Furthermore, the decorative component also includes: two headlight mounting plates, which are disposed on both sides of the plate along the width direction of the vehicle. The front end of the headlight mounting plate is bonded and fixed to the first plate, and the rear end is riveted to the first plate by rivets.

[0022] According to the above technical means, the front end of the headlight mounting plate is fixed to the first plate with adhesive, and the rear end is riveted to the first plate to ensure the reliability and durability of the connection. Specifically, the headlight mounting plate is bonded to the first plate with adhesive.

[0023] Furthermore, the vehicle front trim system also includes a headlight bracket, and a first buckle is provided on the side of the headlight mounting plate opposite to the first plate. The first buckle engages with the headlight bracket and is inclined relative to the horizontal plane.

[0024] According to the above technical means, by setting a first buckle on the side of the headlight mounting plate away from the first plate body, and the first buckle engaging with the headlight bracket, the headlight bracket is fixedly connected to the headlight mounting plate; the first buckle is tilted so that in the event of a collision, the first buckle deforms obliquely downward along its extension direction, absorbing part of the energy, optimizing the energy absorption effect, further improving pedestrian protection performance, and improving the stability and safety of the headlight installation, avoiding the appearance defects and strength problems that may be caused by traditional welding methods.

[0025] Furthermore, the vehicle front trim system also includes two fenders, which are respectively disposed on both sides of the front hood along the width direction of the vehicle and located on the rear side of the trim piece. The fenders are provided with fender brackets, and the trim piece is snapped into the fender brackets.

[0026] Based on the above-mentioned technical means, by setting a fender bracket on the fender and snapping the trim piece with the fender bracket, the assembly process between the trim piece and the fender is made simpler, avoiding the process complexity and appearance defects caused by traditional welding or bolt connection. Furthermore, the fender bracket is pre-installed on the fender, ensuring that the gap between the trim piece and the fender is uniform, improving the overall assembly quality and appearance consistency, and increasing assembly efficiency.

[0027] A vehicle includes: a vehicle body; and the aforementioned front vehicle trim system, the front vehicle trim system being located at the front of the vehicle body.

Compared with traditional vehicles without decorative elements, the cavity design significantly enhances the energy absorption effect and effectively improves the pedestrian protection function. Furthermore, since the decorative element is added to the bumper and is not integrated with the bumper, it does not weaken the structural strength of the decorative element and the bumper itself. At the same time, the cavity has openings on both the front and rear sides, and the first surface is inclined with the front lower and the rear higher. During vehicle operation, the cavity acts as an airflow channel, guiding the airflow from the front of the vehicle to the upper side of the front cover, reducing aerodynamic drag, thereby significantly reducing the drag coefficient and effectively improving aerodynamic performance. This significantly optimizes the vehicle's driving economy, making it more efficient and energy-saving. Moreover, during the flow of air through the cavity, it applies downward pressure to the bumper, increasing the vehicle's grip and thus improving safety and handling.

Compared with traditional welding, it avoids appearance defects such as weld marks and can also avoid the injury of the pedestrian to the weld marks, thereby improving the pedestrian protection performance.

[0032] (4) By setting a support column on the second plate and supporting the second plate on the first surface through the support column, the present invention ensures the structural strength of the decorative part, strengthens the reliability of the connection between the decorative part and the bumper, and the support column can divide the cavity, thereby reducing air turbulence and optimizing aerodynamic performance.

The snap-fit ​​structure is relatively simple, the cost is low, and the connection is stable and reliable.

[0034] (6) The structure of the buckle and the buckle hole of this utility model is relatively simple and easy to process. The metal buckle has good rigidity and toughness and high connection strength, ensuring reliable connection performance under normal working conditions. And / or, the buckle claw can be inserted into the second buckle hole to achieve the buckle engagement. The structure is simple and easy to assemble. The injection molded buckle claw has a certain elastic deformation ability, which can absorb some energy when the vehicle is in collision, prevent the decorative parts from falling off the bumper, and further improve the pedestrian protection performance.

[0035] (7) This utility model ensures the reliability and durability of the connection by using adhesive to fix the front end of the headlight mounting plate to the first plate and rivets to the rear end of the headlight mounting plate. Specifically, the headlight mounting plate is bonded to the first plate by adhesive.

[0036] (8) This utility model provides a first buckle on the side of the headlight mounting plate away from the first plate, and the first buckle is engaged with the headlight bracket, so that the headlight bracket is fixedly connected to the headlight mounting plate; the first buckle is inclined so that when there is a collision, the first buckle deforms obliquely downward along its extension direction to absorb some energy, optimize the energy absorption effect, further improve the pedestrian protection performance, and improve the stability and safety of the headlight installation, avoiding the appearance defects and strength problems that may be caused by traditional welding methods.

Detailed Implementation

[0053] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0054] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0055] The following is combined with Figures 1 to 14 The following describes embodiments of the present invention.

[0056] This embodiment proposes a vehicle front decoration system, including: a front cover 4, a bumper 2, and a decorative element 1. The bumper 2 has a first surface 210, which is disposed on the front side of the front cover 4. The first surface 210 is inclined relative to the horizontal plane. The first surface 210 has a first side 201 away from the front cover 4 and a second side 202 close to the front cover 4. The first side 201 is lower than the second side 202. The decorative element 1 covers at least a portion of the first surface 210. The decorative element 1 has a plate portion 10 spaced apart from the first surface 210. A cavity 7 is formed between the plate portion 10 and at least a portion of the first surface 210. An air inlet 701 is formed on the side of the cavity 7 away from the front cover 4, and an air outlet 702 is formed on the side of the cavity 7 close to the front cover 4.

[0057] It should be noted that in a vehicle, the front is at the front and the rear is at the rear. In this embodiment, the vehicle front trim system is located at the front of the vehicle. Bumper 2 refers to the front bumper of the vehicle. The first surface 210 is a surface that slopes upward from front to back. The area covered by the trim 1 is a critical area for pedestrian protection. When the vehicle is placed on the ground, the side of the vehicle away from the ground is the upper side, and the side closer to the ground is the lower side. Specifically, the front side refers to... Figure 1 The first side 201 being lower than the second side 202 in the direction of the "front" indicated by the middle arrow means that the first side 201 is located below the second side 202 in the height direction of the vehicle.

[0058] The vehicle front trim system of this embodiment covers at least a portion of the bumper 2 with a trim piece 1. The panel 10 of the trim piece 1 is spaced apart from the first surface 210 of the bumper 2, causing the panel 10 to float above the bumper 2. A cavity 7 is formed between the panel 10 and the bumper 2. When a pedestrian collides with the trim piece 1, the cavity 7 provides sufficient crumple space for the trim piece 1. Compared to vehicles without trim pieces, the design of the cavity 7 significantly enhances energy absorption and effectively improves pedestrian protection. Furthermore, the trim piece 1 is an additional addition to the bumper 2 and is not integrated with it. The body will not weaken the structural strength of the decorative part 1 and the bumper 2. At the same time, the cavity 7 has openings on the front and rear sides, and the first surface 210 is inclined with the front lower and the rear higher. During the vehicle's operation, the cavity 7 acts as an airflow channel, guiding the airflow from the front of the vehicle to the upper side of the front cover 4, reducing aerodynamic drag, thereby significantly reducing the drag coefficient and effectively improving aerodynamic performance. This significantly optimizes the vehicle's driving economy, making it more efficient and energy-saving. Furthermore, as the airflow flows through the cavity 7, it will exert downward pressure on the bumper 2, increasing the car's grip and thus improving safety and handling.

[0059] In summary, the vehicle front trim system of this embodiment integrates air vents and has enhanced energy absorption function, while taking into account pedestrian protection, structural strength and aerodynamic performance, and has high safety and reliability.

[0060] In this embodiment, the plate portion 10 includes a first plate 11, a second plate 12, and a boss 15. The first plate 11 and the second plate 12 are arranged with a gap between them. The second plate 12 is arranged with a gap between it and the first surface 210. The first plate 11 is located on the side of the second plate 12 away from the first surface 210. The boss 15 connects the first plate 11 and the second plate 12. By providing the plate portion 10 with two plates arranged in layers along its thickness direction, and the two plates being supported and connected by the boss 15, the structural strength of the plate portion 10 is ensured. On the other hand, the gap between the two plates can also serve as a buffer space, which can improve the energy absorption effect of the plate portion 10 itself, thereby further enhancing the pedestrian protection function.

[0061] In this embodiment, the first plate 11 spans both sides of the vehicle along its width. The first plate 11 features a streamlined design and a smooth surface, effectively reducing airflow resistance. The second plate 12 is arranged in the middle of the first plate 11 along its width. Both the first and second plates 11 employ a thin-walled design, reducing the weight of the decorative element 1 and optimizing the vehicle's fuel or electricity economy. Furthermore, the thin-walled design increases the distance between the first and second plates 11, ensuring sufficient energy absorption space during a collision and improving pedestrian protection performance. It should be noted that since the plate portion 10 comprises two layers of plates, supported by bosses 15, the overall structural strength of the plate portion 10 can be guaranteed even with a thin-walled design. Specifically, the first plate 11 has a wall thickness of 2.5 mm, ensuring aesthetic quality, while the second plate 12 has a wall thickness of 2 mm, effectively improving structural strength and pedestrian protection performance.

[0062] In this embodiment, the first plate 11 is made of high-impact polypropylene (PP), ensuring both appearance quality and good structural strength; the second plate 12 is made of glass fiber reinforced polypropylene, enhancing structural strength and energy absorption, and serves as both energy absorber and support. Preferably, the surface of the first plate 11 undergoes special treatment to provide UV resistance and aging resistance, ensuring good appearance quality over long-term use.

[0063] In this embodiment, further combining Figure 7 As shown, the boss 15 has a hollow structure. When a vehicle collides with a pedestrian, the hollow boss 15 can collapse and deform to absorb some of the impact energy, reduce the impact force on the pedestrian's head, and further improve the pedestrian protection performance of the decorative part 1.

[0064] Furthermore, the boss 15 has a multi-cavity structure. Compared with the traditional solid structure, the multi-cavity structure has better energy absorption effect and better connection strength. While ensuring that the boss 15 can crumple and deform upon impact, it also ensures the structural strength of the boss 15 itself, thereby ensuring the stability of the boss 15 supported between the first plate 11 and the second plate 12. Optionally, the wall thickness of the boss 15 is 0.8mm. By limiting the wall thickness of the boss 15 with the multi-cavity structure, the crumple of the boss 15 is controllable upon vehicle collision, thereby ensuring that design requirements are met.

[0065] In this embodiment, the edge of the boss 15 facing the first plate is provided with an anti-overflow adhesive baffle to prevent structural adhesive from overflowing during collision, thus maintaining the appearance integrity and aesthetics of the decorative part 1.

[0066] In this embodiment, there are multiple bosses 15, which are distributed at intervals to further improve the relative stability between the first plate 11 and the second plate 12.

[0067] Preferably, there are nine protrusions 15, which are spaced apart in the pedestrian collision contact area, further optimizing the pedestrian protection performance of the vehicle front decoration system.

[0068] In this embodiment, at least one end of the boss 15 is bonded to the first plate 11 or the second plate 12. Bonding is a low-cost and simple method. Compared with traditional welding, it avoids appearance defects such as weld marks and can also prevent weld marks from harming pedestrians, thereby improving pedestrian protection performance.

[0069] In this embodiment, the boss 15 is fixedly connected to the second plate 12, and the end of the boss 15 near the first plate 11 is bonded to the first plate 11. The boss 15 is provided on the second plate 12. Due to the collapse of the boss 15 itself during the collision, the second plate 12 can be prevented from being dented, thus maintaining the aesthetics, consistency and integrity of the appearance.

[0070] It is understood that, as an alternative implementation, the boss 15 can also be fixedly connected to the first plate 11, in which case the end of the boss 15 near the second plate 12 is bonded to the second plate 12; or, the boss 15 is an independent structure, in which case the end of the boss 15 near the first plate 11 is bonded to the first plate 11, and the end of the boss 15 near the second plate 12 is bonded to the second plate 12.

[0071] In this embodiment, the boss 15 is fixedly mounted on the second plate 12, and the first plate 11 is provided with a plurality of adhesive dots 14, at which structural adhesive is applied for further bonding. Figure 5 As shown, a plurality of adhesive dots 14 form multiple adhesive regions, including a first adhesive region, which corresponds to the region where multiple bosses 15 are located. The number of adhesive dots 14 in the first adhesive region is equal to the number of bosses 15, with each boss 15 corresponding to one adhesive dot 14. The bosses 15 are bonded to the first plate 11 using structural adhesive, which can improve the stability of the bond between the bosses 15 and the second plate 12. Specifically, the first adhesive region has 9 adhesive dots 14. The multiple adhesive regions also include a second adhesive region and a third adhesive region arranged along the front-rear direction on both sides of the first adhesive region, and a fourth adhesive region and a fifth adhesive region arranged along the width direction of the vehicle on both sides of the first adhesive region. The second, third, fourth, and fifth adhesive regions are bonded to corresponding positions on the second plate 12, respectively. Each adhesive region has multiple adhesive dots 14, ensuring the uniform distribution of the adhesive dots 14 and ensuring the reliability of the connection between the first plate 11 and the second plate 12. Here, the width direction refers to... Figure 5 The "width direction" indicated by the middle arrow is... Figure 1 The "width direction" indicated by the middle arrow is in the same direction.

[0072] In this embodiment, a high-strength, aging-resistant polyurethane adhesive was selected as the structural adhesive to ensure that it can maintain good bonding performance even after long-term use.

[0073] Compared to the traditional structure that requires welding three layers of plates, the plate 10 in this embodiment simplifies the manufacturing process and reduces costs by setting up a first plate 11 and a second plate 12 in layers and connecting the two plates with structural adhesive. The structural adhesive connection method also avoids the problem of exposed weld points that may occur with traditional welding. Furthermore, by adopting a thin-walled structure for the plates and a cavity structure for the boss 15, the pedestrian protection performance is significantly improved. While improving the appearance quality and refinement of the vehicle, it also significantly improves energy absorption, reliability and production efficiency, providing a brand-new solution for optimizing the overall performance of the vehicle.

[0074] In this embodiment, further combining Figures 8 to 9 As shown, at least one support column is provided on the side of the second plate 12 facing the first surface 210, and the support column is supported between the second plate 12 and the first surface 210. By providing a support column on the second plate 12 and supporting the second plate 12 on the first surface 210 through the support column, the structural strength of the decorative part 1 is ensured, the reliability of the connection between the decorative part 1 and the bumper 2 is enhanced, and the support column can divide the cavity 7, thereby reducing air turbulence and optimizing aerodynamic performance.

[0075] In this embodiment, three support columns are used, spaced apart along the width of the vehicle. These three columns divide the cavity 7 into four independent regions along the width: a first airflow channel 71, a second airflow channel 72, a third airflow channel 73, and a fourth airflow channel 74. This effectively reduces air turbulence and optimizes aerodynamic performance. The width direction refers to… Figure 8 The middle arrow points to the "width direction".

[0076] Specifically, the support column includes two side support columns 123 and one central support column 122. The side support columns 123 are larger than the central support column 122. The two side support columns 123 are symmetrically arranged on both sides of the second plate 12 along the width direction. The side support columns 123 mainly bear the support function. The central support column 122 is located between the two side support columns 123 and is located at the longitudinal centerline of the vehicle. It is used to further enhance the connection stability between the decorative part 1 and the bumper 2 and prevent the decorative part 1 from detaching from the bumper 2.

[0077] In this embodiment, the material of the support column is the same as that of the second plate 12. The support column and the second plate 12 are integrally injection molded, which can improve the reliability of the connection between the support column and the second plate 12 and the overall structure, and also reduce the production cost.

[0078] In this embodiment, the support column adopts a spindle-shaped structure design with a smooth surface, which is conducive to airflow, reduces air turbulence, and further improves aerodynamic performance, providing a reliable technical guarantee for the overall performance optimization of the vehicle.

[0079] The support column in this embodiment improves the structural strength and aerodynamic performance of the vehicle while also taking into account manufacturing efficiency and cost control, which is beneficial to improving the safety and performance of the vehicle.

[0080] It should be noted that the decorative part 1 is located at the front of the car, specifically on the upper side of the bumper 2 and connected to the front side of the front cover 4. A portion of the first surface 210 on the upper side of the bumper 2 is recessed downwards in a "U" shape. This recessed area forms a cavity 7 between itself and the panel 10. The position of the decorative part 1 enables it to effectively guide airflow during vehicle operation, allowing air to enter the cavity 7 from the front of the vehicle through the air intake 701, flow through the cavity 7, and then be guided from the air outlet 702 to be discharged from the upper side of the front cover 4, effectively reducing aerodynamic drag.

[0081] In this embodiment, further combining Figure 4 The diagram shows a cross-sectional view of the positional relationship between the first surface 210 of the bumper 2, the front cover 4, and the plate portion 10 on a cross-section formed by the intersection of the vertical and horizontal directions. The bumper 2 and the front cover 4 are designed to be flush, and the surface difference between the first surface 210 and the upper surface of the front cover 4 is zero. This ensures that the gas flowing out of the air outlet 702 of the cavity 7 can be smoothly discharged to the upper side of the front cover 4 without obstruction during the gas flow, thereby improving the stability of the gas flow and further reducing air resistance. Along the direction from the air inlet 701 to the air outlet 702, the distance between the lower surface of the decorative part 1 and the first surface 210 is basically equal. The air inlet 701 and the air outlet 702 are the same size, which can improve the stability of the gas flow, effectively reduce the noise caused by the air flow, and improve the overall vehicle performance in terms of wind noise. The first surface 210 includes a first skin 211 and a second skin 212. The first skin 211 and the second skin 212 are spliced ​​together in the front-to-back direction. The second skin 212 is located on the extension surface of the first skin 211, that is, the second skin 212 is flush with the first skin 211 to ensure the flatness of the first surface 210.

[0082] In this embodiment, the first surface 210 is inclined relative to the horizontal plane. Optionally, the angle between the first surface 210 and the horizontal plane is 20°, so that after the airflow enters the cavity 7, it applies downward pressure to the bumper 2, thereby improving the vehicle's grip and handling performance.

[0083] The design of cavity 7 in this embodiment not only optimizes airflow and reduces turbulence, but also enhances vehicle handling stability by guiding airflow to apply downward pressure to bumper 2.

[0084] In this embodiment, the second plate 12 is provided with a first snap-fit ​​portion, and the bumper 2 is provided with a second snap-fit ​​portion corresponding to the first snap-fit ​​portion. The first snap-fit ​​portion and the second snap-fit ​​portion snap-fit ​​together. By setting the first snap-fit ​​portion of the second plate 12 to snap-fit ​​the second snap-fit ​​portion on the bumper 2, a stable connection between the second plate 12 and the bumper 2 is achieved, thereby achieving a stable connection of the decorative part 1 on the bumper 2. The snap-fit ​​structure is relatively simple, has low cost, and provides a stable and reliable connection.

[0085] In this embodiment, the first snap-fit ​​portion includes a metal snap-fit ​​124, and the second snap-fit ​​portion includes a first snap-fit ​​hole, with the metal snap-fit ​​124 snapping into the first snap-fit ​​hole. The structure of the snap-fit ​​and snap-fit ​​hole is relatively simple and easy to process, and the metal snap-fit ​​has good rigidity and toughness, resulting in high connection strength and ensuring reliable connection performance under normal working conditions. Preferably, the metal snap-fit ​​124 is made of high-strength low-alloy steel.

[0086] In this embodiment, the first locking hole is an elongated hole extending along the front-rear direction of the vehicle. When the vehicle collides, the metal buckle 124 can move in the front-rear direction within the first locking hole, which has a certain buffering effect, thereby further improving the energy absorption effect.

[0087] In this embodiment, the first engaging portion includes an injection-molded claw 125, and the second engaging portion includes a second engaging hole. The injection-molded claw 125 engages with the second engaging hole. The claw can be inserted into the second engaging hole to achieve engagement. The structure is simple and easy to assemble. Furthermore, the injection-molded claw 125 has a certain elastic deformation capacity, which can absorb some energy during a vehicle collision, preventing the decorative part 1 from detaching from the bumper 2 and further improving pedestrian protection performance. Preferably, the injection-molded claw 125 is made of highly elastic polypropylene material, which has good elastic deformation capacity.

[0088] In this embodiment, the first locking portion includes both a metal buckle 124 and an injection-molded claw 125, and the second locking portion includes both a first locking hole and a second locking hole. The decorative part 1 and the bumper 2 are doubly locked by the metal buckle 124 and the injection-molded claw 125. The metal buckle 124 provides a rigid connection, and the injection-molded claw 125 provides an elastic connection. This combines the advantages of rigid and flexible connections, providing a connection performance that is both rigid and flexible. This ensures the connection strength between the decorative part 1 and the bumper 2, and also improves the energy absorption performance during a collision, significantly improving the connection strength and energy absorption effect, optimizing the overall structural performance, and ensuring the safety and reliability of the vehicle. It can be understood that, as an alternative implementation, the first locking portion may also consist of only one of the metal buckle 124 and the injection-molded claw 125, which can also achieve the connection between the decorative part 1 and the bumper 2.

[0089] Further integration Figure 10As shown, the central support column 122 is equipped with a metal buckle 124, and the central support column 122 is connected to the bumper 2 through the metal buckle 124; the side support column 123 is equipped with both a metal buckle 124 and an injection-molded claw 125, and the side support column 123 is connected to the bumper 2 through the metal buckle 124 and the injection-molded claw 125, realizing double locking of the metal buckle 124 and the injection-molded claw 125, which not only ensures the connection strength, but also has an energy absorption effect.

[0090] Further integration Figure 9 As shown, metal buckles 124 are also provided on both sides of the second plate 12 along the width direction to further enhance the stability of the connection between the second plate 12 and the bumper 2.

[0091] In this embodiment, the decorative component 1 further includes two headlight mounting plates 13. Along the width direction of the vehicle, the two headlight mounting plates 13 are respectively disposed on both sides of the plate portion 10. The front ends of the headlight mounting plates 13 are bonded and fixed to the first plate body 11, and the rear ends are riveted to the first plate body 11 by rivets 126. Here, the width direction refers to... Figures 1 to 2 The middle arrow points to the "width direction"; the front end refers to... Figure 11 The end indicated by the middle arrow in the direction of "front" refers to the rear end. Figure 11 The "rear" end is indicated by the middle arrow. Two headlight mounting plates 13 are respectively fixed to both sides of the first plate 11 along the width direction for mounting the headlights 3. The front ends of the headlight mounting plates 13 are fixed to the first plate 11 with adhesive, and the rear ends are riveted to the first plate 11 with rivets 126 to ensure the reliability and durability of the connection. Specifically, the headlight mounting plates 13 are bonded to the first plate 11 with adhesive.

[0092] In this embodiment, the headlight mounting plate 13 is manufactured using injection molding, which is easy to form and ensures a tight connection with the first plate 11.

[0093] In this embodiment, the vehicle front trim system also includes a headlight bracket 32, further combined with... Figure 12As shown, a first buckle 131 is provided on the side of the headlight mounting plate 13 away from the first plate 11. The first buckle 131 engages with the headlight bracket 32, and the first buckle 131 is inclined relative to the horizontal plane. The headlight bracket 32 ​​is provided on the side away from the headlight mounting plate 13, and the headlight body 31 is connected to the headlight body 31. By setting a first buckle 131 on the side of the headlight mounting plate 13 away from the first plate 11, and engaging the first buckle 131 with the headlight bracket 32, the headlight bracket 32 ​​is fixedly connected to the headlight mounting plate 13. It should be noted that when a vehicle collides, the force experienced by the vehicle includes a horizontal component and a vertical separation. In this embodiment, the first buckle 131 is tilted so that when a collision occurs, the first buckle 131 deforms obliquely downward along its extension direction, absorbing some energy, optimizing the energy absorption effect, further improving pedestrian protection performance, and improving the stability and safety of the headlight installation, avoiding the appearance defects and strength problems that may be caused by traditional welding methods.

[0094] In this embodiment, the angle between the first buckle 131 and the horizontal plane is 45°, which effectively ensures that the first buckle 131 deforms when a pedestrian collides, optimizes the energy absorption effect during the collision, and improves the pedestrian protection performance.

[0095] In this embodiment, there are multiple first clips 131, which can improve the fixing effect of the headlight mounting plate 13 on the headlight bracket 32 ​​and improve stability. Preferably, there are four first clips 131.

[0096] Preferably, the first buckle 131 is made of metal, which has high strength and good stability.

[0097] In this embodiment, the vehicle front trim system further includes two fenders 5, which are respectively disposed on both sides of the front hood 4 along the width direction of the vehicle and located behind the trim piece 1. Fender brackets 51 are provided on the fenders 5, and the trim piece 1 is snapped into the fender brackets 51. By providing fender brackets 51 on the fenders 5 and snapping the trim piece 1 into the fender brackets 51, the assembly process between the trim piece 1 and the fenders 5 is simplified, avoiding the process complexity and appearance defects caused by traditional welding or bolt connections. Furthermore, the pre-installation of the fender brackets 51 on the fenders 5 ensures uniform gaps between the trim piece 1 and the fenders 5, improving overall assembly quality and appearance consistency, and increasing assembly efficiency.

[0098] In this embodiment, the connection method between the decorative part 1 and the headlight 3 and fender 5 ensures the compactness and functionality of the overall layout.

[0099] In this embodiment, the front trim system has a trim piece 1 located at the front of the vehicle, specifically positioned on the upper side of the bumper 2 and connected to the front side of the front hood 4. The trim piece 1 is fixedly connected to the headlights 3 on both sides along the width of the vehicle, and its rear end extends to the front edge of the fender 5. By using plastic instead of steel in the front hood area, it breaks through the styling limitations of existing sheet metal hoods. The addition of the trim piece 1 enhances styling freedom, optimizes the vehicle's appearance, and integrates air vents, avoiding the problem of insufficient strength in existing trim pieces and preventing them from being overturned under high-speed airflow. This significantly improves aerodynamic characteristics and energy absorption, enhancing pedestrian protection in collisions. While improving vehicle safety, it also optimizes fuel economy and productivity, improving the overall performance of the vehicle. This provides a novel solution for the design of automotive front trim pieces, possessing promising market application prospects and promotional value.
