Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and more specifically, to a fender assembly and a vehicle having the same. Background Technology

[0002] In the automotive manufacturing industry, the fender, as one of the important body panels, has always faced numerous challenges in its design and manufacturing. Especially in the fender's die-cutting area, due to its unique geometry and location, springback and twisting are common during stamping, directly affecting the dimensional accuracy and final assembly quality of the part. Currently, addressing these issues mainly relies on repeated optimization after product design, attempting to improve its forming performance by continuously adjusting the shape and dimensional parameters of the die-cutting area, supplemented by manual corrections by fitters during the later debugging phase. However, this method is not only time-consuming and resource-intensive, but its effectiveness is also inconsistent.

[0003] No effective solution has yet been proposed to address the above issues. Summary of the Invention

[0004] The main objective of this invention is to provide a fender assembly and a vehicle having the same, in order to solve the technical problem in the prior art where springback and twisting occur in the fender cutter area during the forming process, resulting in difficulty in controlling dimensional accuracy.

[0010] Furthermore, the fender assembly also includes a second fender assembly, a portion of which is located on the side of the handle assembly away from the wheel, and another portion of which is located on the side of the handle assembly closer to the wheel.

[0011] Furthermore, the second flange assembly includes: a second flange body, which protrudes from the outer surface of the handle assembly; and a reinforcing rib, which is located on the side of the handle assembly facing the wheel and extends along the profile of the fender body.

[0012] Furthermore, the thickness of the second flange body is set to L3, and the thickness of the reinforcing rib is set to L4, with L3 and L4 being set accordingly.

It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0035] Combination Figures 1 to 5 As shown, according to a specific embodiment of this application, a fender assembly is provided.

[0036] like Figure 1 , Figure 2 The fender assembly shown includes: a fender body 10, a handle assembly 11 on the side of the fender body 10 near the vehicle door; a first flange structure 12 on the side of the handle assembly 11 near the wheel, the first flange structure 12 extending toward the wheel.

[0037] The fender body 10, as the main structure of the fender assembly, has a complex shape and dimensions. Its function is to cover and protect the wheels, while also cooperating with other vehicle components (such as doors and hoods). The handle assembly 11 is located on the side of the fender body 10 closest to the vehicle door. The shape and size of the handle assembly directly affect the overlap quality and sealing effect with the door, and is a key part determining the overall assembly precision of the fender.

[0038] The first flange structure 12 is installed on the side of the blade handle assembly 11 near the wheel, and the flange structure is positioned towards the wheel. The height of the first flange structure 12 is controlled within a certain range to reduce springback and twisting during the forming process, thereby ensuring the dimensional stability and reliability of the blade handle assembly. Through the design and positioning of the first flange structure 12, the present invention can effectively control the size of the fender blade handle area, reduce springback and twisting during the forming process, ensure the dimensional accuracy of the parts during assembly, and avoid assembly problems caused by dimensional deviations.

[0039] Traditional methods rely on highly skilled fitters for post-production adjustments to address dimensional issues in the fender handle area. This invention, however, optimizes the first flanging structure during the design phase, reducing the need for post-production adjustments, decreasing reliance on highly skilled workers, simplifying the production process, and lowering production costs. The optimized design shortens mold development cycles and simplifies the design process, thereby improving production efficiency. The rational design of the flanging structure can also reduce part debugging time, further accelerating overall production progress. The stability and consistency of the first flanging structure improve the fit quality between the handle assembly and the door and other body parts, enhancing the assembly precision and sealing performance of the finished fender, thus improving the overall vehicle's appearance and functional performance.

[0040] By applying the technical solution of this invention, through the design and positioning of the first flange structure 12, this invention can effectively control the size of the fender blade area, reduce springback and twisting during the forming process, ensure the dimensional accuracy of the parts during assembly, and avoid assembly problems caused by dimensional deviations.

[0041] Specifically, such as Figure 3As shown, along the axial direction of the wheel, the handle assembly 11 has a width dimension L1, which is greater than 55 mm.

[0042] In the stamping process, especially for complex-shaped components like fenders, material deformation and stress distribution are extremely critical. An excessively narrow cutter handle area can easily lead to localized stress concentration, causing springback and torsion. By setting the width L1 of the cutter handle assembly 11 to be greater than 55mm, this invention can evenly distribute stress within the cutter handle assembly 11, reducing the adverse effects of excessive localized stress. The wider cutter handle assembly 11 provides more stable support, improving the rigidity of the entire fender structure. This helps reduce dimensional deviations caused by structural instability during subsequent assembly, thereby improving the assembly quality and stability of the fender.

[0043] In the fender forming process, mold design and manufacturing are crucial aspects that consume significant costs and time. A design with a width dimension L1 greater than 55mm allows mold designers to employ simpler and more efficient mold structures, reducing the need for precision control and thus lowering mold development costs and timelines.

[0044] Considering the different vehicle models and design requirements, the width of the fender cutter area needs to be flexible. This invention, by specifying a minimum dimension of L1 of 55mm, not only meets basic functional requirements but also adapts to the varying requirements of different vehicle designs regarding fender size and shape, thus improving the versatility and applicability of the solution.

[0045] Specifically, the first flange structure 12 includes: a first flange body 120, one end of which is connected to the lower edge of the handle assembly 11, and the other end of which extends toward the vehicle; the first flange body 120 is provided with a plurality of connecting holes 121, and the first flange body 120 is connected to the decorative panel.

[0046] The first flanging body 120 is formed by folding the lower edge of the blade assembly 11. Its design purpose is to better control the flow and elastic recovery of the material during the forming process, and reduce springback and torsion in the flanging area. By extending the other end of the first flanging body 120 toward the vehicle, not only is the rigidity of the blade assembly increased, but its connection with the door and other body parts is also optimized, ensuring the accuracy and reliability of the fender assembly during assembly.

[0047] Multiple connecting holes 121 on the first flange body 120 are used to connect the first flange structure 12 to the decorative panel or other body panels. The presence of the connecting holes 121 allows the first flange structure 12 to be firmly connected to the decorative panel by screws, rivets or other fasteners, thereby enhancing the overall structural stability and durability. By cooperating with the corresponding fasteners through the connecting holes 121, the relative position of the first flange structure 12 and the decorative panel can be precisely controlled, avoiding dimensional mismatches caused by manual assembly or positioning errors, and improving the assembly accuracy of the fender assembly.

[0048] Specifically, such as Figure 4 As shown, the length of the first flanging body 120 is set to L2, which is less than 30mm. This specific dimension is chosen based on in-depth research into the forming process of the fender handle area, aiming to solve the springback and twisting problems caused by excessive flanging height in traditional designs. By limiting the length of the first flanging body, excessive material deformation can be reduced in the initial forming stage, thereby effectively controlling dimensional stability in subsequent processes. This not only simplifies the mold design and debugging process and reduces the need for highly skilled fitters, but also shortens the overall mold development cycle and improves production efficiency.

[0049] Specifically, the first flange body 120 and the handle assembly 11 are integrally formed. There are no additional connection points between the integrally formed first flange body 120 and the handle assembly 11, which means that the material forms a continuous structure after forming, thereby improving the overall structural strength and rigidity, reducing stress concentration caused by connection points, and reducing the risk of springback and torsion.

[0050] With the one-piece molding design, the dimensional relationship between the first flange body 120 and the handle assembly 11 is completely controlled by the mold, eliminating the dimensional errors that may be introduced by secondary connection, ensuring high dimensional accuracy, and helping to improve the assembly quality and performance of the fender assembly.

[0051] One-piece molding eliminates the extra production steps required for secondary connection, simplifies the production process, reduces production costs, and also reduces production time caused by connection operations, thereby improving overall production efficiency.

[0052] Specifically, the fender assembly also includes a second flanging assembly 13, a portion of which is located on the side of the handle assembly 11 away from the wheel, and another portion of which is located on the side of the handle assembly 11 closer to the wheel.

[0053] The design principle of the second flange assembly 13 is based on the need to balance the structural stress of the fender and enhance the overall structural stability. Distributing the second flange assembly 13 on both sides of the handle assembly 11 can effectively disperse the local stress generated by the forming process and reduce material springback and torsion. In addition, this layout can also improve the rigidity of the handle assembly 11, which plays a key role in maintaining the dimensional accuracy and structural stability of the fender assembly during assembly.

[0054] The second flange assembly 13, with its layout on both sides, increases the overall rigidity of the fender assembly, which is crucial for maintaining the dimensional stability and structural integrity of the fender in complex application environments.

[0055] Specifically, such as Figure 5 As shown, the second flange assembly 13 includes: a second flange body 131, which protrudes from the outer surface of the handle assembly 11; and a reinforcing rib 132, which is located on the side of the handle assembly 11 facing the wheel and extends along the profile of the fender body 10.

[0056] The second flange body 131 is designed to protrude from the outer surface of the handle assembly 11. This protruding structure not only increases the three-dimensionality of the handle assembly 11, but more importantly, by extending outward, it increases the contact area between the flange assembly and the outside world, thereby improving the structural rigidity of the entire fender assembly during forming and subsequent use.

[0057] The protruding design of the second flange body 131, especially its distribution on both sides of the handle assembly 11, can provide more uniform support after the fender is formed, reduce the springback and twisting of the material during the forming process, and enhance the dimensional stability and structural robustness of the fender assembly.

[0058] The reinforcing rib 132 is located on the side of the handle assembly 11 facing the wheel. This location is chosen based on a thorough understanding of the stress analysis of the fender. The area near the wheel experiences greater dynamic stress during driving, and the layout of the reinforcing rib 132 aims to enhance the deformation resistance of this area. The reinforcing rib 132 extends along the profile of the fender body 10. This design ensures the structural consistency between the reinforcing rib and the fender body, optimizes the stress distribution of the material, avoids stress concentration caused by abrupt interruptions in the reinforcing rib, and further improves the structural rigidity and durability of the fender.

[0059] The presence of stiffener 132 not only increases local rigidity, but its design also takes into account the needs of lightweighting and improving overall strength. Through precise dimensional and shape design, stiffener 132 significantly improves material utilization and the overall performance of the fender without significantly increasing the amount of material used.

[0060] Specifically, the thickness of the second flange body 131 is set to L3, and the thickness of the reinforcing rib 132 is set to L4, with L3 and L4 being set accordingly. The corresponding thickness of the second flange body L3 and the reinforcing rib L4 ensures the structural stability and strength consistency of the fender blade area during the forming process.

[0061] By controlling the thickness of the two components, the structural coordination between the second flange assembly 13 and the reinforcing rib 132 is ensured, avoiding assembly difficulties or structural instability caused by structural mismatch.

[0062] The reinforcing rib 132 is located on the side of the handle assembly 11 facing the wheel, mainly responsible for impact resistance and enhancing local rigidity, while the second flange body 131 is distributed on both sides of the handle assembly 11, focusing on optimizing the overall structural stability and aesthetics. The corresponding arrangement of L3 and L4 ensures that the two complement each other in function, jointly improving the overall performance of the fender.

[0063] Specifically, the thickness of both the second flange body 131 and the reinforcing rib 132 is greater than 30mm. This specific parameter selection aims to enhance the structural strength and stability of the fender handle area. By increasing the thickness, better support can be provided during stamping, reducing springback and twisting phenomena in the handle area during forming. The design of the reinforcing rib 132 specifically considers its supplementary role in high-stress areas; its increased thickness not only improves local rigidity but also helps to disperse stress, avoiding product defects caused by stress concentration. When the thickness exceeds 30mm, the handle area exhibits greater resilience under die stamping pressure, is less prone to deformation, thus ensuring the accuracy and consistency of part dimensions, reducing the need for subsequent debugging and optimization, and shortening the overall production cycle.

[0064] Optionally, the design of the flange structure dimensions not only relates to its own strength and rigidity but also directly affects the dimensional control, forming efficiency, and subsequent assembly performance of the fender assembly. When the thickness of the flange structure exceeds 30mm, conventional single-layer flange designs often cannot meet the following requirements: excessively thick flange structures tend to accumulate high internal stress during forming, leading to increased springback and making dimensional control extremely difficult. While simply increasing the thickness can improve rigidity, excessively large flange structure dimensions also increase the structure's weight, affecting overall lightweight performance and potentially disrupting the fender's balance, increasing the risk of torsion. Conventional stamping processes may struggle to accurately form flange structures thicker than 30mm, thus impacting production efficiency and finished product quality.

[0065] In view of the above problems, when the thickness of the flange structure is greater than 30mm, the second flange assembly 13 in this embodiment includes: a second flange body 131, which protrudes from the outer surface of the handle assembly 11; and a reinforcing rib 132, which is located on the side of the handle assembly 11 facing the wheel and extends along the profile of the fender body 10. This optimizes the structural weight of the fender, achieving lightweight design while ensuring structural strength, which is in line with the development trend of modern automotive industry.

[0066] According to one aspect of the present invention, a vehicle is provided, including a fender assembly, the fender assembly being the aforementioned fender assembly.

[0067] In the technical solution of this application, the processing of the fender assembly follows a rigorous forming process. First, the fender body 10 is fed into the mold for preliminary stamping, at which point the shape and size of the handle assembly 11 are initially formed. Then, through precise mold control, the length L2 of the first flange structure 12 is controlled to be less than 30mm during forming to reduce springback caused by excessive flange height. During this process, the first flange body 120 and the handle assembly 11 are integrally formed, ensuring the connection strength and dimensional stability between them. In the mold design stage, the width L1 of the handle assembly 11 along the wheel axis is set to be greater than 55mm. This dimension helps control material flow and reduce twisting during forming. Through this series of parameter optimizations and structural designs, the size and shape of the handle area are precisely controlled after stamping, eliminating the need for extensive post-processing adjustments, reducing reliance on highly skilled fitters, thereby shortening the mold development cycle, reducing production costs, and improving the assembly quality and production efficiency of the fender.

[0068] In another specific embodiment, in order to further enhance the structural stability of the handle area, a second flange assembly 13 is provided, wherein the second flange body 131 protrudes from the outer surface of the handle assembly 11 and works in conjunction with the reinforcing rib 132 to jointly improve the rigidity of the handle area.

[0069] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0070] 1. By studying the forming principle of the fender handle area, the width of the handle assembly was set to be greater than 55mm in the early stage of product design, and the dimensions of the flange structure were optimized to simplify the design process, shorten the mold development cycle, and reduce the technical ability requirements of designers.

[0071] 2. The problem of dimensional control in the handle area was solved during the design phase, avoiding a large amount of fitter work due to dimensional deviations, thereby reducing the workload and cost of later debugging.
