Description

Technical Field

[0001] This application belongs to the field of vehicle body structure technology, and more specifically, relates to a fender reinforcement structure and a vehicle. Background Technology

[0002] As a key vehicle component, the fender covers the outer side of the wheel and is typically made of thin sheet metal, resulting in inherently weak resistance to deformation. It is easily deformed by minor bumps or external forces during daily use. The upper edge of the fender is connected to an upper fender bracket, which corresponds to the junction of the lower side panel and the fender, forming the core support structure of the upper fender. The lower front area of ​​the fender is connected to a lower front fender bracket. One end of the lower front fender bracket is connected to the fender, and the other end is fixed to the front longitudinal beam or front bumper frame. This bracket directly covers the area below the fender near the front wheel steering mechanism and is a crucial component connecting the front of the fender to the front structure of the vehicle body.

[0003] The rigidity of existing fenders is generally insufficient. If the fender's rigidity in the vertical direction is insufficient, it is prone to severe deformation during installation under bolt tightening force or assembly external force, which will prevent the fender from fully fitting with the upper fender bracket. If the fender's rigidity in the lateral direction is insufficient, the gap and surface difference between it and the side panel will not meet the standards. After assembly, uneven gaps and excessive surface differences between the fender and the side panel are likely to occur, damaging the neatness of the vehicle's appearance.

[0004] Furthermore, for some models, the distance between the lower front mounting point and the upper mounting point of the fender is too large, and these mounting points are all located far from the engine compartment side beam. Since the engine compartment side beam is an important rigid support structure at the front of the vehicle, providing stable stress support for surrounding components, the excessive distance between these mounting points and the engine compartment side beam prevents the fender from fully utilizing the support of the side beam to enhance the rigidity of its critical components when connecting to the vehicle body. This directly results in poor rigidity at the upper fender bracket mounting point, the lower front bracket mounting point, and the fender corner stiffness, making it difficult to meet the design standards and performance requirements for fender structural rigidity. Utility Model Content

[0005] The purpose of this application is to provide a fender reinforcement structure and vehicle, which aims to solve the problem that the existing side beams are too far from the fenders and cannot provide sufficient support, resulting in insufficient fender stiffness and easy deformation under stress.

[0006] In a first aspect, embodiments of this application provide a fender reinforcement structure, including: Fender body; A side beam reinforcing plate is disposed on the inner side of the fender body, and the side beam reinforcing plate and the fender body form an installation space in the left-right direction; and A reinforcing component is disposed within the installation space. The reinforcing component is connected to the fender body and the side beam reinforcement plate in the left-right direction, and is also connected to the fender body in the up-down direction. The reinforcing component includes a first support portion and a second support portion distributed at intervals in the front-back direction. The fender body, the first support portion, the side beam reinforcement plate, and the second support portion enclose and form a frame structure.

[0007] The beneficial effects of the fender reinforcement structure provided in this application are as follows: Compared with the prior art, by replacing the original upper and lower front supports of the fender with reinforcement components, the frame structure formed by the fender body, the first support, the side beam reinforcement plate, and the second support not only constructs a stable rigid support system but also possesses excellent energy absorption and buffering characteristics. The reinforcement components are connected to the fender body in both the vertical and horizontal directions, achieving not only the connection between the fender body and the side beam but also improving the connection stability through a multi-point connection scheme. Simultaneously, it enhances the stiffness of the fender body in both the vertical and horizontal directions, effectively solving the problem of insufficient stiffness and easy deformation in existing fenders. When the fender body is subjected to external impact, the frame structure can efficiently absorb and disperse the impact force, avoiding localized dents, warping, and other deformations caused by direct external force. Furthermore, by leveraging the rigid support advantage of the side beams, this application synergistically strengthens the stiffness of the upper mounting point, the lower front mounting point, and the corner points of the fender body, resulting in more uniform stress distribution and a significant improvement in overall deformation resistance. Under external force, the rigid support and energy absorption characteristics of the frame structure not only ensure the assembly accuracy of the gap surface difference between the fender body and the side wall, maintaining the regularity of the vehicle's appearance, but also reduce the risk of external force being transmitted to the vehicle body by dispersing impact force and reducing structural deformation, thus enhancing the overall safety performance of the vehicle.

[0008] In conjunction with the first aspect, in one possible implementation, the reinforcing component includes: The headlight bracket has a first fixing position connected to the fender body in the vertical direction and a second fixing position connected to the fender body in the horizontal direction. A fender reinforcement frame, connected to the headlight bracket and / or the fender body, and connected to the side beam reinforcement plate in the left-right direction, the fender reinforcement frame forming a first support portion; and The front fender bracket is distributed at intervals with the fender reinforcement frame along the front-rear direction. One end of the front fender bracket is connected to the headlight bracket and / or the fender body, and the other end is connected to the side beam reinforcement plate. The front fender bracket forms the second support part.

[0009] In the above technical solution, the headlight bracket is fixed to the fender body in multiple directions and at multiple points by means of a first fixed position that connects to the fender body in the vertical direction and a second fixed position that connects to the fender body in the horizontal direction. This avoids the problem of excessive local stress and easy deformation during the assembly of the fender body caused by a single-direction connection. At the same time, it can strengthen the rigidity of the fender body in the vertical and horizontal directions and effectively improve its resistance to deformation.

[0010] In conjunction with the first aspect, in one possible implementation, the headlight bracket includes: A first support includes a frame and a fixed flange connected to the frame, the fixed flange having a first fixing position, and the fender reinforcement frame connected to the frame; and The second bracket is distributed at an angle to the frame body. The second bracket extends in the front-to-back direction and is connected to the fender body in the left-to-right direction. The second bracket has the second fixing position. The front bracket of the fender is connected to the second bracket.

[0011] In the above technical solution, the fixed flange of the first bracket is provided with a first fixed position for connecting the fender body in the vertical direction, and the frame is also firmly connected to the fender reinforcement frame, forming a rigid support point in the upper region; the second bracket is distributed at an angle to the frame of the first bracket and extends in the front-rear direction. It not only achieves a reliable connection with the fender body in the left-right direction through its own second fixed position, but also provides a stable connection foundation for the front bracket of the fender, constructing a force support point in the lower front region.

[0012] In conjunction with the first aspect, in one possible implementation, the first support further includes a first reinforcing plate connected to the frame body, the first reinforcing plate and the fixed flange being connected to opposite ends of the frame body, and the second support has a second reinforcing plate bent inward, the second reinforcing plate being connected to the first reinforcing plate.

[0013] In the above technical solution, the headlight bracket, while taking into account the functions of the original upper and lower fender brackets and connecting the upper and lower mounting points of the fender body, improves its impact resistance and deformation resistance, can stably transmit support force, strengthen the rigidity of the fender body in the vertical and horizontal directions, and ensure that the fender body always maintains structural stability under assembly or external force, thus ensuring the assembly accuracy of the front of the vehicle and the overall safety performance.

[0014] In conjunction with the first aspect, in one possible implementation, the second support has reinforcing ribs extending in a front-rear direction, and the reinforcing ribs are distributed at intervals from top to bottom.

[0015] In the aforementioned technical solution, the second bracket, by incorporating multiple reinforcing ribs extending along the front-rear direction and spaced apart from top to bottom, forms multiple continuous force transmission paths, significantly enhancing its structural strength and resistance to deformation. These reinforcing ribs not only effectively disperse impact forces from the front of the vehicle, preventing concentrated external forces from causing localized bending or damage to the second bracket, but also evenly transmit impact forces to surrounding connecting components through continuous force transmission, reducing the likelihood of excessive localized stress on the fender body.

[0016] In conjunction with the first aspect, in one possible implementation, the fender reinforcement frame includes a fixed plate and a connecting plate distributed at an angle, and also includes a connecting flange connected to the connecting plate. The fixed plate is connected to the headlight frame in the front-rear direction, and the connecting flange is connected to the side beam reinforcement plate in the left-right direction.

[0017] In the above technical solution, the fixing plate connects to the front light frame along the front-rear direction, which can bear the force transmitted by the front light frame and distribute it to surrounding components, avoiding local stress concentration. The connecting plate and the fixing plate are distributed at an angle, which not only optimizes the structural space layout but also enhances the overall bending resistance. The connecting flange is tightly connected to the side beam reinforcement plate along the left-right direction, forming a rigid transmission channel between the fender reinforcement frame and the side beam, which can fully utilize the strong support characteristics of the side beam to enhance the rigidity of the relevant areas of the fender.

[0018] In conjunction with the first aspect, in one possible implementation, the fender reinforcement frame further includes a reinforcing plate connected to the fixed plate and the connecting plate, wherein the fixed plate, the connecting plate and the reinforcing plate are sequentially connected to form a stable triangular structure.

[0019] In the aforementioned technical solution, the fender reinforcement frame forms a stable triangular structure through the sequential connection of reinforcing plates, fixed plates, and connecting plates. This fully utilizes the inherent geometric stability of the triangular structure, enhancing its strength, rigidity, and resistance to deformation. This triangular structure can evenly distribute the force to the three sides and vertices, effectively resisting external impacts and stresses from multiple directions, including front, rear, left, and right. It avoids bending, displacement, and other deformation problems at the connection between the fixed plate and the connecting plate. Compared to traditional planar or linear connection structures, the load-bearing capacity and structural stability are qualitatively improved.

[0020] In conjunction with the first aspect, in one possible implementation, the front fender bracket includes: A first connecting plate includes a first support body and a first connecting body distributed at an angle, the first connecting body being connected to the fender body in a left-right direction; and The second connecting plate includes a second support body and a second connecting body distributed at an angle. The second connecting body is connected to the side beam reinforcing plate in the left and right directions, and the second support body is connected to the first support body.

[0021] In the above technical solution, the first support body of the first connecting plate and the first connecting body are distributed at an angle, which not only optimizes the stress angle of the structure, but also forms an effective support point on the front side of the fender by firmly connecting the first connecting body to the fender body in the left and right direction. The second support body of the second connecting plate and the second connecting body also adopt an angled design. With the help of the second connecting body, it is closely connected to the side beam reinforcement plate in the left and right direction, and a transmission channel with the rigid support of the side beam is built. The reliable connection between the second support body and the first support body forms a cooperative stress system.

[0022] In conjunction with the first aspect, in one possible implementation, the front fender bracket includes a bracket body and a reinforcing flange connected to the outer edge of the bracket body.

[0023] In the aforementioned technical solution, the front fender bracket enhances its edge strength and overall rigidity by incorporating a reinforcing flange on its outer edge, thereby improving its resistance to bending and deformation. The reinforcing flange disperses localized stress in the outer edge area, preventing edge warping or bending during external forces or long-term use. Simultaneously, it strengthens the overall structural stability of the bracket, ensuring its structural regularity during force transmission and support of the fender.

[0024] Secondly, embodiments of this application also provide a vehicle including the aforementioned fender reinforcement structure.

[0025] The beneficial effects of the vehicle provided in this application are as follows: Compared with the prior art, it adopts the aforementioned fender reinforcement structure. By replacing the original upper and lower fender supports with reinforcement components, the frame structure formed by the fender body, the first support part, and the second support part of the side beam reinforcement plate not only constructs a stable rigid support system but also possesses excellent energy absorption and buffering characteristics. The reinforcement components are connected to the fender body in the vertical and horizontal directions, respectively. This not only achieves the connection between the fender body and the side beam but also improves the connection stability through a multi-point connection scheme. Simultaneously, it enhances the stiffness of the fender body in the vertical and horizontal directions, effectively solving the problem of insufficient stiffness and easy deformation of existing fenders. When the fender body is subjected to external impact, the frame structure can efficiently absorb and disperse the impact force, avoiding local dents, warping, and other deformations caused by direct external force. Furthermore, this application leverages the rigid support advantage of the side beam to synergistically strengthen the stiffness of the upper mounting point, the lower front mounting point, and the corner points of the fender body, making the stress on the fender body more uniform and significantly improving the overall deformation resistance. Under external force, the rigid support and energy absorption characteristics of the frame structure not only ensure the assembly accuracy of the gap surface difference between the fender body and the side wall, maintaining the regularity of the vehicle's appearance, but also reduce the risk of external force being transmitted to the vehicle body by dispersing impact force and reducing structural deformation, thus enhancing the overall safety performance of the vehicle.

Detailed Implementation To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0029] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] 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 technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "a few" means two or more, unless otherwise explicitly specified.

[0031] It should be noted that the directions or positional relationships indicated by "front", "rear", "inner", "outer", "up", and "down" in this embodiment are based on the vehicle's own orientation. The front of the vehicle represents "front", the rear of the vehicle represents "rear", the top of the vehicle represents "up", the bottom of the vehicle represents "down", the "inner" side refers to the side facing the driver's cab, and the "outer" side refers to the side facing the driver's cab.

[0032] In addition, the front-rear direction of the vehicle body as defined in the embodiments of this application refers to the front-rear direction of the vehicle's forward direction during driving; the left-right direction of the vehicle body as defined refers to the left-right direction of the vehicle's forward direction during driving; and the up-down direction of the vehicle body as defined refers to the up-down direction of the vehicle's forward direction during driving.

[0033] It should be noted that since the "inner" side of a vehicle refers to the side facing the driver's cab, "the side beam reinforcement plate is located on the inner side of the fender body" means that in the left-right direction, the side beam reinforcement plate is located on the side of the fender body closer to the driver's cab.

[0034] Please refer to the following: Figures 1 to 3 The fender reinforcement structure and vehicle provided in this application are described below. The fender reinforcement structure includes a fender body 1, a side beam reinforcing plate 2, and a reinforcing assembly. The side beam reinforcing plate 2 is disposed on the inner side of the fender body 1, and the side beam reinforcing plate 2 and the fender body 1 form an installation space in the left-right direction. The reinforcing assembly is disposed within the installation space and is connected to the fender body 1 and the side beam reinforcing plate 2 in the left-right direction, and is also connected to the fender body 1 in the up-down direction. The reinforcing assembly includes a first support part and a second support part distributed at intervals in the front-rear direction. The fender body 1, the first support part, the side beam reinforcing plate 2, and the second support part enclose and form a frame structure.

[0035] Compared with existing technologies, the fender reinforcement structure provided in this application replaces the original upper and lower front supports of the fender with reinforcing components. The frame structure formed by the fender body 1, the first support, the side beam reinforcement plate 2, and the second support not only constructs a stable rigid support system but also possesses excellent energy absorption and buffering characteristics. The reinforcing components are connected to the fender body 1 in the vertical and horizontal directions, respectively. This not only achieves the connection between the fender body 1 and the side beam but also improves the connection stability through a multi-point connection scheme. Simultaneously, it enhances the stiffness of the fender body 1 in both the vertical and horizontal directions, effectively solving the problem of insufficient stiffness and easy deformation in existing fenders. When the fender body 1 is subjected to external impact, the frame structure can efficiently absorb and disperse the impact force, avoiding local dents, warping, and other deformations caused by direct external force. Furthermore, this application leverages the rigid support advantage of the side beams to synergistically strengthen the stiffness of the upper mounting point, the lower front mounting point, and the corner points of the fender body 1, resulting in more uniform stress distribution and a significant improvement in overall deformation resistance. Under external force, the rigid support and energy absorption characteristics of the frame structure not only ensure the assembly accuracy of the gap surface difference between the fender body 1 and the side wall, maintaining the regularity of the vehicle's appearance, but also reduce the risk of external force being transmitted to the vehicle body by dispersing impact force and reducing structural deformation, thus enhancing the overall safety performance of the vehicle.

[0036] Specifically, the top of the fender body 1 has a mounting flange, which is connected to the reinforcing component in the vertical direction.

[0037] Please see Figures 1 to 3 In some embodiments, the reinforcing components include a headlight bracket 3, a fender reinforcement frame 4, and a fender front bracket 5. The headlight bracket 3 has a first fixed position connected to the fender body 1 in a vertical direction and a second fixed position connected to the fender body 1 in a horizontal direction. The fender reinforcement frame 4 is connected to the headlight bracket 3 and / or the fender body 1, and is connected to the side beam reinforcement plate 2 in a horizontal direction, forming a first support portion. The fender front bracket 5 is spaced apart from the fender reinforcement frame 4 in a front-rear direction, with one end connected to the headlight bracket 3 and / or the fender body 1 and the other end connected to the side beam reinforcement plate 2, forming a second support portion.

[0038] The headlight bracket 3, with its first fixed position connecting vertically to the fender body 1 and a second fixed position connecting horizontally to the fender body 1, achieves multi-directional and multi-point fixation with the fender body 1. This avoids the problem of excessive local stress and deformation during assembly caused by a single-direction connection, while also strengthening the rigidity of the fender body 1 in both vertical and horizontal directions, effectively improving its resistance to deformation. The fender reinforcement frame 4 and the front fender bracket 5 are distributed at intervals along the front-rear direction, providing support to the headlight bracket 3 in different areas. This avoids uneven strength distribution caused by concentrated connections, making the overall stress distribution of the headlight bracket 3 more stable and ensuring the stability of the connection with the fender body 1.

[0039] In addition, the fender reinforcement frame 4 and the fender front bracket 5 are both connected to the side beam reinforcement plate 2 in the left and right directions, forming a two-way rigid transmission path between the fender body 1 and the side beam reinforcement plate 2. With the help of the rigid support advantage of the side beam, the rigidity of the key installation area of ​​the fender body 1 can be strengthened, and a frame support structure can be formed. When subjected to external impact, the impact force can be efficiently dispersed, reducing the risk of local deformation.

[0040] Optionally, the headlight bracket 3 extends in the front-rear direction, which not only provides sufficient installation space for the fender reinforcement bracket 4 and the fender front bracket 5, but also provides reinforcement force to the key areas of the fender body 1, reducing the probability of the fender body 1 being concave under stress.

[0041] Optionally, the fender reinforcement frame 4 is connected to the headlight bracket 3, using the headlight bracket 3 as an intermediate medium to connect with the fender body 1. Alternatively, the fender reinforcement frame 4 can be connected to both the fender body 1 and the headlight bracket 3 simultaneously, or directly to both the fender body 1. The fender front bracket 5 is connected to the side beam reinforcement plate 2, with its other end connected to the headlight bracket 3 and / or the fender body 1. All of the above solutions can achieve a frame structure formed by the first support, the fender body, the second support, and the side beam reinforcement plate, and can be selected according to actual needs.

[0042] Please see Figure 2 and Figure 3 In some embodiments, the headlight bracket 3 includes a first bracket 301 and a second bracket 302. The first bracket 301 includes a frame 3011 and a fixed flange 3012 connected to the frame 3011. The fixed flange 3012 has a first fixing position. The fender reinforcement bracket 4 is connected to the frame 3011. The second bracket 302 is distributed at an angle to the frame 3011. The second bracket 302 extends in the front-rear direction and is connected to the fender body 1 in the left-right direction. The second bracket 302 has a second fixing position. The fender front bracket 5 is connected to the second bracket 302.

[0043] The first bracket 301 has a fixed flange 3012 with a first fixed position for connecting the fender body 1 in the vertical direction. The frame 3011 is also firmly connected to the fender reinforcement frame 4, forming a rigid support point in the upper region. The second bracket 302 is distributed at an angle to the frame 3011 of the first bracket 301 and extends in the front-rear direction. It not only achieves a reliable connection with the fender body 1 in the left-right direction through its own second fixed position, but also provides a stable connection foundation for the front fender bracket 5, constructing a stress support point in the lower front region. In this embodiment, the multi-directional and multi-point connection scheme effectively disperses the local stress of the fender body 1, avoids the deformation problem caused by stress concentration at a single connection point, and at the same time, the cooperative structure of the first bracket 301 and the second bracket 302 has higher strength, which can specifically enhance the deformation resistance of the fender body 1, making the overall stress of the fender body 1 more uniform, and further ensuring its assembly accuracy with surrounding components.

[0044] Optionally, the first bracket 301 and the second bracket 302 are formed into an integral component by stamping.

[0045] Please see Figure 2 In some embodiments, the first bracket 301 further includes a first reinforcing piece 3013 connected to the frame 3011, the first reinforcing piece 3013 and the fixed flange 3012 are connected to opposite ends of the frame 3011, and the second bracket 302 has a second reinforcing piece 3022 bent inward, the second reinforcing piece 3022 is connected to the first reinforcing piece 3013.

[0046] The first reinforcing plate 3013 and the fixed flange 3012 of the first bracket 301 are respectively connected to the opposite ends of the frame 3011 to prevent the frame 3011 from bending, warping or other deformation problems due to force in one direction. The second reinforcing plate 3022 of the second bracket 302 bends inward and is firmly connected to the first reinforcing plate 3013. This not only makes the first bracket 301 and the second bracket 302 form an integrated rigid connection structure, but also increases the force transmission path between the first bracket 301 and the second bracket 302, achieving a fast and multi-channel force transmission effect. In this solution, the front light bracket 3, while taking into account the functions of the original upper and lower fender brackets and connecting the upper and lower mounting points of the fender body 1, improves its impact resistance and deformation resistance, can stably transmit support force, strengthen the rigidity of the fender body 1 in the vertical and horizontal directions, and ensure that the fender body 1 always maintains structural stability under assembly or external force, thus ensuring the assembly accuracy and overall safety performance of the front of the vehicle.

[0047] Optionally, the fixed flange 3012, the frame 3011 and the first reinforcing plate 3013 are connected in sequence to form a "Z" shaped structure or a "U" shaped structure.

[0048] Optionally, the first reinforcing plate 3013 and the second reinforcing plate 3022 overlap and connect in the vertical direction.

[0049] Please see Figure 2 In some embodiments, the second support 302 has reinforcing ribs 3021 extending in the front-rear direction, and multiple reinforcing ribs 3021 are distributed at intervals from top to bottom.

[0050] The second bracket 302, by incorporating multiple reinforcing ribs 3021 extending longitudinally and spaced from top to bottom, forms multiple continuous force transmission paths, significantly enhancing its structural strength and resistance to deformation. The reinforcing ribs 3021 not only effectively disperse impact forces from the front of the vehicle, preventing concentrated external forces from causing localized bending or damage to the second bracket 302, but also evenly transmit impact forces to surrounding connecting components through continuous force transmission, reducing the likelihood of excessive localized stress on the fender body 1. Simultaneously, the spaced reinforcing ribs 3021 further strengthen the structural rigidity of the second bracket 302 without adding excessive weight, ensuring structural stability during the support of the fender body 1 and connection to the front fender bracket 5. This, in turn, synergistically improves the overall rigidity and impact resistance of the fender body 1, guaranteeing the assembly precision of the fender and surrounding components.

[0051] Optionally, the top and bottom of the second support 302 are provided with reinforcing flanges. The two sets of reinforcing flanges bend in opposite directions. The two sets of reinforcing flanges bending in opposite directions can effectively resist the torsion, warping and other deformations generated by the second support 302 when under stress, avoid the structural stress imbalance caused by a single bending direction, and at the same time enhance the bending resistance and edge strength of the second support 302 in the vertical direction.

[0052] Optionally, adjacent reinforcing ribs 3021 are interconnected, forming an integrated rigid network from the originally independent reinforcing ribs 3021. This breaks the stress limitation of a single reinforcing rib 3021. When subjected to an impact force from the front of the vehicle, the impact force can be quickly and evenly transmitted and diffused between the reinforcing ribs 3021 through the connecting nodes, avoiding structural damage caused by local stress concentration and improving the impact resistance and deformation resistance of the second support 302.

[0053] Please see Figures 2 to 3 In some embodiments, the fender reinforcement frame 4 includes a fixed plate 401 and a connecting plate 402 distributed at an angle, and also includes a connecting flange 403 connected to the connecting plate 402. The fixed plate 401 is connected to the front light frame 3 in the front-rear direction, and the connecting flange 403 is connected to the side beam reinforcement plate 2 in the left-right direction.

[0054] The fixing plate 401 connects to the front light frame 3 along the front-rear direction, bearing the force transmitted by the front light frame 3 and distributing it to surrounding components to avoid localized stress concentration. The connecting plate 402 is angled to the fixing plate 401, optimizing the structural spatial layout and enhancing the overall bending resistance. The connecting flange 403 is tightly connected to the side beam reinforcing plate 2 along the left-right direction, constructing a rigid transmission channel between the fender reinforcement frame 4 and the side beam, fully utilizing the strong support characteristics of the side beam to enhance the rigidity of the relevant areas of the fender. The multi-directional force transmission structure formed by the fixing plate 401, connecting plate 402, and connecting flange 403 not only improves the structural stability and load-bearing capacity of the fender reinforcement frame 4 itself, but also achieves efficient force transmission between the front light frame 3 and the side beam reinforcing plate 2, further enhancing the deformation resistance of the fender body 1, ensuring the assembly accuracy of the fender and surrounding components, and providing reliable support for the overall stability and safety of the vehicle's front structure.

[0055] Please see Figure 3 In some embodiments, the fender reinforcement frame 4 also includes a reinforcing plate 404 connected to the fixed plate 401 and the connecting plate 402, and the fixed plate 401, the connecting plate 402 and the reinforcing plate 404 are connected in sequence to form a stable triangular structure.

[0056] The fender reinforcement frame 4 forms a stable triangular structure by sequentially connecting the reinforcing plate 404, the fixed plate 401, and the connecting plate 402. This fully utilizes the inherent geometric stability of the triangular structure, enhancing its strength, rigidity, and resistance to deformation. This triangular structure can evenly distribute the force to the three sides and vertices, effectively resisting external impacts and stresses from multiple directions such as front, back, left, and right. It avoids bending, displacement, and other deformation problems at the connection between the fixed plate 401 and the connecting plate 402. Compared with traditional planar or linear connection structures, the load-bearing capacity and structural stability are qualitatively improved.

[0057] Meanwhile, the triangular structure further enhances the reliability of the fender reinforcement frame 4 as an intermediate transmission link, ensuring that the force transmitted by the headlight bracket 3 can be efficiently transmitted to the side beam reinforcement plate 2 through a stable structural path. This fully utilizes the rigid support advantage of the side beam to improve the stiffness and impact resistance of key areas of the fender body 1. Furthermore, the stable triangular structure also ensures the structural integrity of the fender reinforcement frame 4 under long-term use or complex stress scenarios, reducing assembly gap deviations caused by structural deformation and maintaining the assembly accuracy of the fender and surrounding components.

[0058] Please see Figure 2In some embodiments, the fender front bracket 5 includes a first connecting plate 501 and a second connecting plate 502. The first connecting plate 501 includes a first support body 5012 and a first connector body 5011 distributed at an angle. The first connector body 5011 is connected to the fender body 1 in the left-right direction. The second connecting plate 502 includes a second support body 5022 and a second connector body 5021 distributed at an angle. The second connector body 5021 is connected to the side beam reinforcing plate 2 in the left-right direction. The second support body 5022 is connected to the first support body 5012.

[0059] The first support body 5012 of the first connecting plate 501 is angled to the first connecting body 5011, which optimizes the structural stress angle and provides a stable connection between the first connecting body 5011 and the fender body 1 in the left-right direction, forming an effective support point on the front side of the fender. Similarly, the second support body 5022 of the second connecting plate 502 is angled to the second connecting body 5021. The second connecting body 5021 is tightly connected to the side beam reinforcement plate 2 in the left-right direction, establishing a transmission channel with the rigid support of the side beam. The reliable connection between the second support body 5022 and the first support body 5012 forms a collaborative stress-bearing system. This solution not only enhances the bending and deformation resistance of the fender front support 5 itself, evenly distributing external forces from the front-rear and left-right directions to avoid structural damage caused by localized stress concentration, but also achieves efficient force transmission between the fender body 1 and the side beam reinforcement plate 2, fully utilizing the support advantages of the side beam to strengthen the rigidity of the lower front area of ​​the fender. Meanwhile, the structural design is precisely adapted to the installation space layout, ensuring coordinated operation with the headlight bracket 3 and fender reinforcement bracket 4, and improving the stability of the overall fender support system.

[0060] Optionally, the second support 5022 and the first support 5012 both extend in the left-right direction and are connected in the front-back direction.

[0061] Optionally, the first connecting plate 501 and the second connecting plate 502 are integral components.

[0062] Please see Figure 2 In some embodiments, the front fender bracket 5 includes a bracket body 503 and a reinforcing flange 504 connected to the outer edge of the bracket body 503.

[0063] The fender front bracket 5, by incorporating a reinforcing flange 504 on the outer edge of the bracket body 503, enhances its edge strength and overall rigidity, thereby improving its resistance to bending and deformation. The reinforcing flange 504 disperses localized stress in the outer edge area, preventing edge warping or bending of the bracket body 503 under external force or during long-term use. It also strengthens the overall structural stability of the bracket body 503, ensuring its structural regularity during force transmission and support of the fender body 1. This design does not require excessive additional installation space while improving the load-bearing capacity of the fender front bracket 5, ensuring a more stable and reliable connection between it and the fender body 1, the side beam reinforcing plate 2, and the headlight bracket 3, and optimizing the force transmission efficiency of the overall fender support system.

[0064] Based on the same inventive concept, this application also provides a vehicle. The vehicle includes the aforementioned fender reinforcement structure.

[0065] The vehicle provided by this utility model adopts a fender reinforcement structure. By replacing the original upper and lower fender supports with reinforcement components, the frame structure formed by the fender body 1, the first support part, the side beam reinforcement plate 2, and the second support part not only constructs a stable rigid support system but also possesses excellent energy absorption and buffering characteristics. The reinforcement components are connected to the fender body 1 in both the vertical and horizontal directions, achieving not only the connection between the fender body 1 and the side beam but also improving the connection stability through a multi-point connection scheme. This also enhances the rigidity of the fender body 1 in both the vertical and horizontal directions, effectively solving the problem of insufficient rigidity and easy deformation in existing fenders. When the fender body 1 is subjected to external impact, the frame structure can efficiently absorb and disperse the impact force, avoiding local dents, warping, and other deformations caused by direct external force. Furthermore, this application leverages the rigid support advantage of the side beam to synergistically strengthen the rigidity of the upper mounting point, the lower front mounting point, and the corner points of the fender body 1, resulting in more uniform stress distribution and a significant improvement in overall deformation resistance. Under external force, the rigid support and energy absorption characteristics of the frame structure not only ensure the assembly accuracy of the gap surface difference between the fender body 1 and the side wall, maintaining the regularity of the vehicle's appearance, but also reduce the risk of external force being transmitted to the vehicle body by dispersing impact force and reducing structural deformation, thus enhancing the overall safety performance of the vehicle.

[0066] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
