[0002] Currently, the side support of the front bumper is a one-piece structure, which is strong and not easily deformed to absorb energy. However, it cannot collapse and absorb energy in the event of a side impact, which can easily cause injury to pedestrians. At the same time, since the front continuous headlight is the main styling trend of new energy vehicles, and most new energy vehicles have eliminated the radiator grille at the front, the front bumper side is extremely difficult to assemble, or even impossible to assemble, due to factors such as the front continuous headlight obstructing the view of the radiator grille and the lack of a visible opening for the radiator grille. Furthermore, assembly personnel and quality inspectors cannot check whether the front bumper side mounting points are properly installed, resulting in poor visibility of the DTS (Difference Tolerance System) dimensions at the front of the vehicle. Summary of the Invention

Therefore, they should not be construed as limitations on this invention.

[0019] Please refer to the following: Figures 1 to 7 The front bumper side support structure provided by the present invention will now be described. The front bumper side support structure includes a first bracket 1 and a second bracket 2. The first bracket 1 is fixed to the front frame of the vehicle frame; the second bracket 2 is fixed to the front anti-collision beam 4 of the vehicle frame; the second bracket 2 is also connected to the first bracket 1, and the connection between the second bracket 2 and the first bracket 1 constitutes the mounting position of the front through headlight 3; the second bracket 2 has an arched bend 22 that arches forward towards the vehicle body.

[0020] Compared with the prior art, the side support structure of the front bumper provided by the present invention has the following advantages: (1) The first bracket 1 is tightly connected to the front frame, and the second bracket 2 is tightly connected to the front anti-collision beam 4. At the same time, the second bracket 2 is designed as an arched structure that arches towards the front of the vehicle body. The front side has a good crumple energy absorption effect. When the left and right sides of the vehicle collide with pedestrians, it is easy to crumple and deform to absorb energy, thereby reducing the damage to pedestrians. While protecting pedestrians, it can meet the pedestrian safety protection design requirements and improve the overall vehicle safety pedestrian protection C-NCAP and A-NCAP score; (2) At the same time, this support structure provides installation support for the installation of the front through headlight 3, which can reduce the pulling force of the front bumper side on the front through headlight 3 and reduce the risk of cracking and water leakage of the front through headlight 3; (3) Through the second The arched design of bracket 2 can raise the height to the upper edge of the front bumper, making the front bumper more visible during assembly, reducing the difficulty of assembling the side of the front bumper and the inability to inspect after assembly, improving the accuracy of the side assembly of the front bumper, ensuring the overall coordination of the gaps and steps of the vehicle side, and making the front bumper assembly and the front through headlight 3 meet the DTS size technical specifications of the front of the vehicle, improving the visual effect of the vehicle appearance, enhancing the refined perception of the front of the vehicle, and adapting to the current trend of through headlights and front grille-less radiator design in new energy vehicles; (4) This structure provides a connection for the front through headlight 3, the front bumper and the front frame and the front anti-collision beam 4, provides support for the side of the front bumper assembly, and carries the bumper assembly and the front through headlight 3 to meet the DTS size technical specifications of the front of the vehicle, improving the visual perception effect of the user.

[0021] DTS (Dimensional Technical Specifications) is a technical document that defines the nominal values ​​and tolerances of the internal and external clearances, surface differences, and other parameters of a vehicle. It serves as the target for vehicle product design, manufacturing processes, and quality control.

[0022] In some embodiments, such as Figures 1 to 7 As shown, the second bracket 2 is a sheet metal part. The arched bend 22 has a first connecting part 21 and a second connecting part 23 at both ends. The first connecting part 21 is fixed to the first bracket 1, and the second connecting part 23 is fixed to the front bumper beam 4. Specifically, the first bracket 1 is located above the second bracket 2. The upper end of the second bracket 2 is fixed to the first bracket 1, and the lower end of the second bracket 2 is fixed to the front bumper beam 4. Specifically, the overall shape of the second bracket 2 is similar to a "Z" shape.

[0023] This embodiment utilizes the high extensibility of sheet metal brackets to raise the height to the upper edge of the front bumper, which improves the visibility of assembly and quality inspection personnel, facilitates assembly line correction, and allows quality inspectors to conduct follow-up checks, achieving dual assurance, improving assembly quality, reducing after-sales problems, and solving the problem of blind assembly of the front bumper being unable to be properly installed due to the conventional side support arrangement being too low in height and the lack of a radiator grille viewing hole. At the same time, it improves the production efficiency and production cycle of the production line.

[0024] In some embodiments, such as Figures 1 to 3 As shown, the arched bend 22 has a trapezoidal structure, and a weakening hole 221 is provided on the upper bottom of the arched bend 22. Since the left and right sides of the front of the vehicle are the areas most likely to collide with pedestrians, conventional one-piece plastic supports are too strong and not easily deformed. The combination of the trapezoidal structure of the support structure and the weakening hole 221 in this embodiment not only meets the high load-bearing capacity and high precision requirements of the front side of the vehicle, but also has the characteristics of high toughness and easy energy absorption in the front-rear direction, which improves the crumple and weakening effect of the front side, greatly improves the protection of the pedestrian's thighs and lower legs, and increases the score of pedestrian protection collision C-NCAP and A-NCAP.

[0025] C-NCAP Explanation: The China Automotive Technology and Research Center (CATARC) officially released the first version of the China New Car Assessment Program (C-NCAP) on March 2, 2006. C-NCAP employs stricter and more comprehensive requirements to conduct all-round safety performance tests on vehicles, including occupant protection, pedestrian protection, and active safety, thereby providing consumers with more systematic and objective vehicle safety information and encouraging automakers to continuously improve the overall safety performance of their vehicles.

[0026] To further explain, the trapezoidal structure includes two bases and two side edges. The side length of the upper base is shorter than that of the lower base. Here, the upper base is located in front of the lower base. From the perspective of the arch structure, the upper base is located at the highest point of the arch. The upper base protrudes forward and is the first to contact the pedestrian or external object in a side collision. Therefore, the weakening hole 221 is set on the upper base. When a side collision occurs, the upper base is more likely to collapse and absorb energy. Compared with a rigid object that is not easy to collapse and deform, it can reduce the injury to the pedestrian.

[0027] In some embodiments, such as Figures 1 to 3 As shown, reinforcing ribs 222 are provided on both sides of the arched bend 22, which can improve the support strength of the support structure and increase its load-bearing capacity in the vertical direction.

[0028] In some embodiments, such as Figures 1 to 3 , Figure 6 As shown, the second bracket 2 is fixedly connected to the first bracket 1 by fasteners, and the front through-type headlight 3 is fixed to the second bracket 2 by fasteners. This solution utilizes the first bracket 1 to provide a high-precision mounting point and limit for the front through-type headlight 3, while also providing a fastening point for the second bracket 2. It simultaneously achieves a convenient one-through-three installation that satisfies the fastening installation of the headlight and the second bracket 2, simplifying the installation structure and improving the ease of installation.

[0029] In some embodiments, such as Figures 1 to 3 , Figure 6 As shown, the first bracket 1 is an integrally injection molded part. The first bracket 1 has a support platform 11 that supports the second bracket 2. The support platform 11 also forms the mounting position of the front through headlight 3. The support platform 11 is provided with a first fixing hole 12 for connecting fasteners. The second bracket 2 is provided with a second fixing hole 211 for fasteners to pass through. This embodiment combines the high precision and molding versatility of plastic parts with the high strength, high toughness, and energy absorption characteristics of sheet metal parts. By utilizing the high extensibility of sheet metal parts, the vertical height is increased to the upper edge of the bumper, greatly improving the visibility of assembly and quality inspection personnel. This facilitates assembly line correction and quality inspection review, achieving dual assurance and reducing after-sales issues. Compared with conventional one-piece plastic supports, the reinforced structure of the arched bending part 22 and the corresponding weakening hole 221 meet the requirements of high load-bearing capacity and high precision on the side, while also possessing high toughness and energy absorption characteristics in the front and rear directions to achieve crumple and weakening at the front. This greatly improves the protection of pedestrians' upper and lower legs and enhances the pedestrian protection collision ratings in C-NCAP and A-NCAP.

[0030] In some embodiments, such as Figures 1 to 3 As shown, the support platform 11 is also provided with a positioning pin 14, and the second bracket 2 is provided with a positioning pin hole that matches the positioning pin 14, so as to facilitate the assembly of the second bracket 2 and the first bracket 1.

[0031] In some embodiments, such as Figures 1 to 3 As shown, the support platform 11 is also equipped with positioning ribs 13 for the installation and positioning of the front through headlight 3. When the lower edge of the front through headlight 3 abuts against the positioning ribs 13, the front through headlight 3 is installed in the vertical direction. The first bracket 1 not only provides an installation point for the front through headlight 3, but also provides a positioning structure, which improves the installation efficiency and installation position accuracy of the front through headlight 3.

[0032] The support platform 11 is provided with positioning ribs 13 on the left and right sides respectively. The first connecting part 21 of the second bracket 2 is located between the two positioning ribs 13. Therefore, the positioning ribs 13 also constitute the anti-rotation structure of the second bracket 2.

[0033] In some embodiments, such as Figure 4 As shown, the first bracket 1 is provided with a fastening hole 15 for fastening the front frame, a main positioning hole 16, and an auxiliary positioning hole 17. The auxiliary positioning hole 17 is an oblong hole. The oblong auxiliary positioning hole 17 serves to pre-position the fastening hole 15, facilitating its alignment and adjustment.

[0034] The installation process of the support structure provided in this embodiment is as follows: The first bracket 1 is pre-installed on the front frame through the auxiliary positioning hole 17, and then reliably positioned through the main positioning hole 16. Then it is fastened to the front frame through three fastening holes 15. The upper end of the second bracket 2 is pre-attached to the first bracket 1 through a positioning pin 14 and two positioning ribs 13. The lower end of the second bracket 2 is fastened to the front anti-collision beam 4 through the through-hole bolt. The upper end of the second bracket 2 achieves high precision in the support area through effective positioning. Its lower end effectively absorbs and solves the uncontrollability of low assembly precision of the front anti-collision beam through the through-hole. The installation of the first bracket 1 and the second bracket 2 is completed. Then, the front through-light 3, the second bracket 2 and the first bracket 1 are fastened together by bolts passing through the second fixing hole 211 of the second bracket 2 and the first fixing hole 12 of the first bracket 1. Finally, the front bumper is assembled to complete the matching of the side of the vehicle.

[0035] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0037] The vehicle provided in this embodiment of the invention features a second bracket 2 that arches forward, providing a crumple zone and energy absorption effect in the front-to-back direction. This effectively absorbs the energy transmitted from a frontal impact, thereby reducing injuries to the pedestrian's upper and lower legs and improving the vehicle's pedestrian protection crash test ratings in C-NCAP and A-NCAP. The mounting position for the front continuous headlight 3 solves problems such as headlight cracking and water leakage caused by excessive tension applied to the headlight 3 by the front bumper. Simultaneously, it ensures the side-fitting accuracy between the front bumper and the front continuous headlight 3, meets the overall vehicle DTS dimensional requirements, enhances the overall refined appearance of the front of the vehicle, and aligns with the current trend of continuous headlights and grille-less front radiator design in new energy vehicles.
