Description

Technical Field

[0001] This application relates to the field of vehicle body structure technology, and in particular to a fender assembly and a vehicle. Background Technology

[0002] The fender is located on the side of the front engine compartment of the vehicle, above the wheel. The fender is usually fixed to the body by its own bracket structure. The inside of the fender is adjacent to the closed engine compartment cover, the front end is adjacent to the headlights and bumper, and the rear end is adjacent to the front door.

[0003] To ensure the fender has sufficient structural strength and prevent dents when pressed, the fender assembly typically consists of multiple components, including the fender itself, fender mounting brackets, and fender reinforcement plates. However, this structural design results in a large number of components and processes, requiring numerous molds and tooling, leading to lower installation accuracy and higher development costs.

[0004] At the same time, the conventional design mentioned above not only results in heavy components, which is not conducive to the requirements of lightweighting and weight reduction and energy saving, but also makes it easy for the upper part or head of the human body to collide with the fender when the vehicle is involved in a frontal pedestrian collision. Due to the presence of various high structural strength mounting brackets, fender reinforcement plates, etc., the fender can cause serious impact injuries to pedestrians, reducing the pedestrian protection performance of the vehicle. Utility Model Content

[0005] In view of this, this application aims to provide a fender assembly to improve the safety protection performance of the fender assembly in the event of a pedestrian collision.

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

[0007] A fender assembly includes a fender body and a mounting bracket integrally formed on the edge of the fender body. The fender body is fixed to a vehicle body via the mounting bracket. The mounting bracket includes a side mounting bracket located on the inner edge of the fender body, and the side mounting bracket is provided with a collapsible structure. When the fender body is subjected to an external impact, the collapsible structure can induce the side mounting bracket to collapse and deform, causing the fender body to collapse toward the interior of the vehicle.

[0008] Furthermore, it also includes a support frame disposed inside the fender body, the support frame forming a support between the vehicle body and the fender body.

[0009] Furthermore, the fender body, the mounting bracket, and the support frame are all made of carbon fiber.

[0010] Furthermore, the support frame is a long strip with multiple bends, and the thickness of both the support frame and the fender body is set between 1.2mm and 2.5mm.

[0011] Furthermore, the support frame is provided with an abutment protrusion that abuts against the fender body, and an adhesive platform disposed adjacent to the abutment protrusion; there is a gap between the adhesive platform and the fender body, and they are connected by adhesive filling the gap.

[0012] Furthermore, both ends of the support frame are provided with the abutment protrusion and the bonding platform, and the middle part of the support frame is spaced apart from the fender body.

[0013] Furthermore, the side mounting bracket is bent into a stepped distribution of sealing strip mounting platforms and engine compartment cover assembly platforms. In the direction from the outside to the inside of the vehicle body, the fender body, the sealing strip mounting platforms, and the engine compartment cover assembly platforms are arranged in a staggered manner. The sealing strip mounting platforms are used to support the engine compartment sealing strips, and the engine compartment cover assembly platforms are used to abut against the engine compartment cover. The collapsible structure includes a first structural weakening hole on the connecting plate between the sealing strip mounting platforms and the engine compartment cover assembly platforms.

[0014] Furthermore, relative to the side connecting the connecting plate, the other side of the engine compartment cover assembly platform is provided with a support leg; the support leg extends from the engine compartment cover assembly platform toward the interior of the vehicle body, and the bottom of the support leg is bent into a foot for fixing the vehicle body.

[0015] Furthermore, the collapse structure also includes a second structural weakening hole provided on the nacelle cover assembly platform.

[0016] Compared with related technologies, this application has the following advantages:

[0017] (1) The fender assembly of this application integrally forms a mounting bracket at the edge of the fender body for mounting and fixing the fender body on the vehicle body. This reduces the number of structural components such as fender mounting brackets and fender reinforcing plates, and improves the integration and minimization of the fender assembly design. At the same time, a crumple structure is provided on the side mounting bracket located inside the fender body. When a pedestrian collision occurs at the front of the vehicle, the pedestrian's head or upper body hits the fender body. With the crumple guiding effect of the crumple structure, the fender body can collapse and indent to improve the buffering effect and reduce the degree of injury to the pedestrian. This is beneficial to improving the safety protection performance of the fender assembly in the event of a pedestrian collision.

[0018] (2) A support frame is installed between the inner side of the fender body and the vehicle body, which can provide good support for the fender body, improve the structural stability of the fender body, and prevent the fender body from denting when it is pressed.

[0019] (3) The fender body and mounting bracket are made of carbon fiber and hot-pressed into one structure. The support frame is also made of carbon fiber, which not only meets the structural strength requirements of the fender assembly, but also greatly reduces the overall weight of the fender assembly, thereby improving the lightweight design level of the fender assembly.

[0020] (4) The support frame is made of long strips of plate, which are bent to form the required support structure, which can well meet the support requirements of different spatial dimensions between the fender body and the car body. Since both the fender body and the support frame are plate structures, limiting the thickness of the plate to a reasonable range not only ensures the structural stability of the fender assembly, but also minimizes material consumption and maintains the lightweight design level of the fender assembly.

[0021] (5) For the parts of the support frame that need to be connected to the vehicle body, fixing holes can be set, and the vehicle body can be fixed by bolts passing through the fixing holes to achieve reliable installation and fixing of the support frame on the vehicle body; For the parts of the support frame that contact the fender body, adjacent abutment protrusions and bonding platforms can be set. The protrusion height of the abutment protrusion can limit the gap size between the bonding platform and the fender body. By filling the gap with glue, the bonding platform can be firmly bonded to the fender body, thereby ensuring the bonding reliability between the fender body and the support frame.

[0022] (6) Abutment protrusions and adhesive platforms are provided at both ends of the support frame, which can reliably bond the two ends of the support frame to the fender body; a certain size gap is maintained between the middle of the support frame and the fender body, which not only allows for flexible provision of parts for connecting the vehicle body on the support frame, and then opening fixing holes in these parts; but also provides sufficient space for the fender body to collapse when subjected to strong external impact, thus ensuring the crumple buffer energy absorption effect of the fender body when a pedestrian collision occurs.

[0023] (7) A connecting plate arranged vertically is required between the sealing strip mounting platform and the naval cover assembly platform. By opening multiple first structural weakening holes on the connecting plate, the structural strength of the connecting plate can be effectively weakened. When the fender body is subjected to a strong external impact, the part where the first structural weakening hole is located on the connecting plate is easily bent, deformed and collapsed, thereby realizing the rapid collapse of the fender body. This can greatly improve the collapse buffer energy absorption effect of the fender body and reduce the degree of injury to pedestrians.

[0024] (8) A support leg is provided on the side of the engine compartment cover assembly platform to achieve a fixed connection with the vehicle body. While meeting the assembly position requirements of the engine compartment cover assembly platform and the engine compartment cover, the support leg can also be extended to the vehicle body to achieve a reliable fixed connection between the fender body and the vehicle body, thereby reliably installing the inner side of the fender body onto the vehicle body.

[0025] (9) A second structural weakening hole is provided on the engine compartment cover assembly platform, which can further improve the collapse deformation performance of the side mounting bracket, thereby meeting the energy absorption and buffering requirements of the fender assembly when a pedestrian collision occurs at the front of the vehicle, and thus improving the safety protection performance during a pedestrian collision.

[0026] Another object of this application is to provide a vehicle equipped with the fender assembly described in this application. The vehicle of this application possesses the technical advantages of the aforementioned fender assembly. Attached Figure Description

[0042] To make the technical solution and advantages of 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 not intended to limit the scope of this application.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0044] Furthermore, it should be stated in the description of this application that if terms indicating orientation or positional relationship, such as "up," "down," "left," "right," "front," "rear," "inner," and "outer," appear, they are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and for clarity and conciseness of expression, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0046] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0047] In the publicly available technologies, to ensure the fender has sufficient structural strength and prevent dents when pressed, the fender assembly typically consists of multiple components, including the fender itself, fender mounting brackets, and fender reinforcement plates, thus guaranteeing the fender's structural strength. However, this structural design results in a large number of components and processes, as well as a large number of molds and tooling, leading to poor installation accuracy and high development costs for the fender assembly.

[0048] Furthermore, especially when steel or aluminum alloy is used for the fenders, the fender assembly is heavy, which is detrimental to the requirements of lightweighting and energy saving. In the event of a frontal pedestrian collision, the upper part or head of the pedestrian is likely to hit the fender. Due to the presence of various high-strength mounting brackets and fender reinforcement plates, the fender can cause serious impact injuries to pedestrians, reducing the vehicle's pedestrian protection performance. In addition, the heavy weight of steel or aluminum alloy fenders, while hindering the requirements of lightweighting and energy saving, also limits the ability to form complex shapes for some models.

[0049] In view of the above-mentioned problems in the related technologies, this application innovatively proposes a brand-new fender assembly that can improve the safety protection performance of the fender assembly in the event of a pedestrian collision.

[0050] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0051] An embodiment of the first aspect of this utility model provides a fender assembly applicable to the front side of various vehicle models; one exemplary structure is as follows: Figure 1 , Figure 2 and Figure 3 As shown.

[0052] Overall, the fender assembly includes a fender body 1 and a mounting bracket integrally formed on the edge of the fender body 1. The fender body 1 is fixed to the vehicle body by the mounting bracket. The mounting bracket includes a side mounting bracket 4 located on the inner edge of the fender body 1, and the side mounting bracket 4 is provided with a collapsible structure. When the fender body 1 is subjected to an external impact, the collapsible structure can induce the side mounting bracket 4 to collapse and deform, causing the fender body 1 to collapse towards the interior of the vehicle.

[0053] It should be noted that, based on the above-mentioned overall design concept, the technical solution of this application can adopt a variety of different specific implementation structures, forms, or configuration sequences. For example, the fender body 1 mentioned above can be integrally stamped from sheet metal made of metal, or integrally hot-pressed from carbon fiber material; the collapsible structure on the side mounting bracket 4 can be achieved by opening holes, reducing the thickness of the plate, adding a fracture 44, etc. For the parts required for the implementation of the overall solution but not covered in the above overall setup, reasonable and flexible designs can be made by referring to mature design methods in the field and the actual situation during implementation, which will not be elaborated here. The specific implementation schemes described below in this embodiment are only one of the many solutions that can be formed by the various combinations and variations mentioned above. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the various solutions that can be formed by the combinations and variations of the above-mentioned specific forms, as well as the specific implementation schemes of this embodiment, are all within the protection scope of this application.

[0054] Regarding the specific configuration of the side mounting bracket 4, there are naturally many different structural options available; for example, flexible brackets, legs, and other structural forms can be used. In this embodiment, such as... Figure 2 and Figure 4 As shown, in some preferred exemplary embodiments, the side mounting bracket 4 is bent into a stepped distribution of a sealing strip mounting platform 40 and a hood mounting platform 42; in the direction from the outside to the inside of the vehicle body, the fender body 1, the sealing strip mounting platform 40 and the hood mounting platform 42 are arranged in a staggered manner; wherein, the sealing strip mounting platform 40 is used to support the hood sealing strip, and the hood mounting platform 42 is used to abut against the hood, and when closed, it can abut against the hood mounting platform 42 to obtain a certain support.

[0055] On the side mounting bracket 4, sealing strip mounting platforms 40 and nacelle cover mounting platforms 42 are staggered in sequence, providing a reasonable position and reliable installation foundation for the installation of the nacelle sealing strip located between the nacelle cover and the fender body 1. It also plays a supporting role for the nacelle cover, so that the nacelle cover can be closed reliably and securely. After the nacelle cover is closed, the nacelle cover abuts against the nacelle cover mounting platform 42, and the nacelle sealing strip is clamped between the nacelle cover and the fender body 1. The nacelle sealing strip can play a good role in ensuring a good seal between the nacelle cover and the fender body 1.

[0056] Furthermore, to improve the installation accuracy of the engine compartment sealing strip on the sealing strip mounting platform 40, positioning holes 400 are provided on the sealing strip mounting platform 40 to correspond to the positioning protrusions and other structures on the engine compartment sealing strip. The cooperation between the positioning protrusions and the positioning holes 400 on the engine compartment sealing strip improves the accuracy of the installation position and ease of assembly of the engine compartment sealing strip on the sealing strip mounting platform 40, preventing positional shifting or displacement of the engine compartment sealing strip. Simultaneously, a first mounting hole 421 can be provided on the engine compartment cover mounting platform 42, and a recess 422 can be provided at the location of the first mounting hole 421. The first mounting hole 421 is located at the bottom of the recess 422. Using the first mounting hole 421, bolts can be passed through to secure the engine compartment cover mounting platform 42 to the vehicle body, and buffer blocks, gaskets, etc., can also be fixed on the engine compartment cover mounting platform 42 to provide a buffering effect between the engine compartment cover mounting platform 42 and the engine compartment cover.

[0057] Based on the above-described configuration of the side mounting bracket 4, the aforementioned crumple structure includes a first structural weakening hole 410 located on the connecting plate 41 between the sealing strip mounting platform 40 and the nacelle cover mounting platform 42. The first structural weakening hole 410 can be of different shapes such as circular, triangular, or rectangular. In this embodiment, the first structural weakening hole 410 is rectangular and extends along the edge of the fender body 1. A plurality of first structural weakening holes 410 are evenly distributed on the connecting plate 41 at intervals. Given that the sealing strip mounting platform 40 and the cabin cover mounting platform 42 are staggered vertically, a connecting plate 41 arranged vertically is required between them. By opening multiple first structural weakening holes 410 on the connecting plate 41, the structural strength of the connecting plate 41 can be effectively weakened. When the fender body 1 is subjected to a strong external impact, the part where the first structural weakening holes 410 on the connecting plate 41 are located can easily bend, deform and collapse, thereby achieving rapid collapse of the fender body 1. This can greatly improve the collapse buffer energy absorption effect of the fender body 1 and reduce the degree of injury to pedestrians.

[0058] Continue as Figure 4 , Figure 5 and Figure 6 As shown, in some preferred exemplary embodiments, a support leg 43 is provided on the other side of the engine compartment cover mounting platform 42 relative to the connecting plate 41. The support leg 43 extends from the engine compartment cover mounting platform 42 toward the interior of the vehicle body, and the bottom of the support leg 43 is bent to form a foot 430 for fixing to the vehicle body. A second mounting hole 431 can be provided on the foot 430, and bolts can be passed through the second mounting hole 431 to be screwed to the vehicle body, thereby fixing the support leg 43 to the vehicle body.

[0059] A support leg 43 is provided on the side of the engine compartment cover assembly platform 42 to achieve a fixed connection with the vehicle body. While meeting the assembly position requirements of the engine compartment cover assembly platform 42 and the engine compartment cover, the support leg 43 can also be extended to the vehicle body to achieve a reliable fixed connection between the fender body 1 and the vehicle body, thereby reliably installing the inner side of the fender body 1 onto the vehicle body.

[0060] Of course, one or more outriggers 43 can be provided; in this embodiment, such as Figure 4 As shown, along the edge of the fender body 1, the nacelle cover mounting platform 42 extends in a long strip, with three support legs 43 spaced apart on its side. To further enhance the structural weakening effect of the nacelle cover mounting platform 42, the aforementioned crumple zone structure also includes a second structural weakening hole 420 on the nacelle cover mounting platform 42. Preferably, the second structural weakening hole 420 is also a plurality of holes spaced apart along the length of the nacelle cover mounting platform 42. Simultaneously, a break 44 can be made in the nacelle cover mounting platform 42 between the front support leg 43 and the middle support leg 43, thereby dividing the nacelle cover mounting platform 42 into a front section 42a and a main body section 42b. This further enhances the structural weakening effect of the nacelle cover mounting platform 42, thereby improving the collapse and energy absorption effect of the fender assembly during a collision. The second structural weakening hole 420 and the break 44 are provided on the hood plate assembly platform 42, which can further improve the collapse deformation performance of the side mounting bracket 4, thereby meeting the energy absorption and buffering requirements of the fender assembly when a pedestrian collision occurs at the front of the vehicle, and thus improving the safety protection performance during pedestrian collisions.

[0061] Of course, for reference Figure 1 , Figure 2 As shown, in addition to the side mounting bracket 4, the aforementioned mounting bracket may also include a front mounting bracket 2 located at the front end of the fender body 1 and a rear mounting bracket 3 located at the rear end of the fender body 1. Given that the front end of the fender body 1 typically has a headlight clearance hole 10, the front mounting bracket 2 can be configured as two sets, with the two sets of front mounting brackets 2 located on the left and right sides of the headlight clearance hole 10 respectively. The configuration of the front mounting bracket 2 and the rear mounting bracket 3 ensures that the front and rear ends of the fender body 1 are reliably fixed to the vehicle body, while also ensuring the installation reliability of the fender assembly.

[0062] In addition, continue as Figures 4 to 9 As shown, in some preferred exemplary embodiments, the fender assembly further includes a support frame 5 disposed inside the fender body 1, which can form a support between the vehicle body and the fender body 1. Providing the support frame 5 between the inside of the fender body 1 and the vehicle body can provide good support for the fender body 1, improve the structural stability of the fender body 1, and prevent the fender body 1 from denting when pressed.

[0063] Of course, one or more support frames 5 can be provided, specifically for areas on the fender body 1 that are structurally weak and easily dented by pressure. In this embodiment, three support frames 5—a first support frame 51, a second support frame 52, and a third support frame 53—are spaced apart at the middle and rear of the fender body 1. The specific structure of each support frame 5 can be designed reasonably and flexibly according to the specific spatial conditions between the fender body 1 and the vehicle body.

[0064] like Figure 7 , Figure 8 and Figure 9 As shown, in some preferred exemplary embodiments, each support frame 5 is a long strip plate with multiple bends, and the thickness of both the support frame 5 and the fender body 1 is between 1.2mm and 2.5mm. The support frame 5 is made of a long strip plate, and by bending it to form the required support structure, it can well meet the support requirements of different spatial dimensions between the fender body 1 and the vehicle body. Since both the fender body 1 and the support frame 5 are plate structures, limiting the thickness of the plates within a reasonable range not only ensures the structural stability of the fender assembly but also minimizes material consumption, maintaining the lightweight design level of the fender assembly.

[0065] Furthermore, preferably, the fender body 1, mounting bracket, and support frame 5 are all made of carbon fiber. The fender body 1 and mounting bracket are integrally formed by hot pressing carbon fiber, and the support frame 5 is also made of carbon fiber. This not only meets the structural strength requirements of the fender assembly but also significantly reduces the overall weight of the fender assembly, thereby improving the lightweight design level of the fender assembly. Moreover, in the event of a pedestrian collision, the carbon fiber fender, being more flexible than steel, will inevitably reduce the degree of injury to the human body.

[0066] In addition, the support frame 5 of this embodiment is also provided with an abutment protrusion 501 that abuts against the fender body 1, and an adhesive platform 502 disposed adjacent to the abutment protrusion 501. There is a gap between the adhesive platform 502 and the fender body 1, and by filling the gap between the adhesive platform 502 and the fender body 1 with adhesive 6, the adhesive platform 502 and the fender body 1 can be firmly bonded together, thereby realizing the fixed connection between the support frame 5 and the fender body 1. For the parts of the support frame 5 that need to be connected to the vehicle body, fixing holes 500 can be provided. The support frame 5 can be reliably installed and fixed on the vehicle body by passing bolts through the fixing holes 500. For the parts of the support frame 5 that contact the fender body 1, adjacent abutment protrusions 501 and bonding platforms 502 can be provided. The protrusion height of the abutment protrusion 501 can limit the gap size between the bonding platform 502 and the fender body 1. By filling the gap with glue 6, the bonding platform 502 can be firmly bonded to the fender body 1, thereby ensuring the bonding reliability between the fender body 1 and the support frame 5.

[0067] Continue to refer to, for example Figures 7 to 9 As shown, in some preferred exemplary embodiments, the abutment protrusion 501 and the bonding platform 502 form a set of bonding structures. Each end of the support frame 5 is provided with a set of abutment protrusions 501 and bonding platforms 502. These two sets of bonding structures can respectively bond the two ends of the support frame 5 to the fender body 1. Simultaneously, the middle part of the support frame 5 is spaced apart from the fender body 1. The abutment protrusions 501 and bonding platforms 502 at both ends of the support frame 5 reliably bond the two ends of the support frame 5 to the fender body 1. Maintaining a certain size gap between the middle part of the support frame 5 and the fender body 1 not only allows for flexible provision of parts on the support frame 5 for connecting to the vehicle body, and thus opening fixing holes 500 in these parts; but also, the gap space between the fender body 1 and the support frame 5 provides sufficient space for the fender body 1 to collapse under strong external impact, ensuring the crumple buffer energy absorption effect of the fender body 1 in the event of a pedestrian collision.

[0068] Based on the above exemplary embodiments, as a preferred combination of the exemplary solutions, refer to Figures 1 to 9 As shown, the specific implementation of the fender assembly in this embodiment can refer to the following overall scheme:

[0069] Both the fender body 1 and the mounting bracket integrally formed on the fender body 1 are made of carbon fiber. Compared with the conventional design where multiple fender mounting brackets and fender reinforcing plates are set on the inner edge of the fender body 1, the fender assembly in this embodiment has a side mounting bracket 4 integrally formed on the inner part of the fender body 1, integrating the aforementioned multiple fender mounting brackets and fender reinforcing plates into one piece. At the same time, a crumple zone structure is designed on the side mounting bracket 4 to achieve safety protection in the event of a pedestrian collision, as well as the requirements for fewer parts and lighter weight design of the fender assembly.

[0070] While a side mounting bracket 4 is provided on the inner edge of the fender body 1, a front mounting bracket 2 and a rear mounting bracket 3 are respectively provided at the front and rear ends of the fender body 1; multiple support brackets 5 are also bonded to the inner side of the fender body 1; both the fender body 1 and the support brackets 5 are made of carbon fiber, and the thickness of the plate can be reasonably selected between 1.2mm and 2.5mm; for example, it can be set to 1.2mm, 1.38mm, 1.8mm, 2.4mm, etc. If the plate thickness of the fender body 1 and the support brackets 5 is less than 1.2mm, it will seriously affect the structural performance of the component itself and make it difficult to meet the structural strength requirements of the fender body 1 and the support brackets 5; if the plate thickness is greater than 2.5mm, it will unnecessarily increase the weight of the component and cause material waste.

[0071] When installing the support frame 5, both ends of the support frame 5 can be abutted against the fender body 1 through the abutting protrusions 501, and the bonding platform 502 can be bonded to the fender body 1 through the adhesive 6; at the same time, several fixing holes 500 are provided in the middle of the support frame 5, and bolts, screws, etc. can be used to pass through the fixing holes 500 to achieve a fixed connection with the vehicle body.

[0072] As can be seen, compared with the fender structure of traditional models, the fender assembly of this application integrates the fender body 1, the side mounting bracket 4 that cooperates with the engine hood, and the front mounting bracket 2 and side mounting bracket 4 at the front and rear ends of the fender body 1 into a single component, realizing the design requirements of integration and fewer parts.

[0073] The side mounting bracket 4 adopts a continuous bending structure with an approximate "W" shaped cross-section. It not only provides installation points for the engine compartment sealing strip but also provides a mating surface for the engine compartment cover, which helps to improve the installation matching accuracy of the assembly. It can also effectively cover various installation holes at the mating points of the fender assembly and the engine compartment cover, thereby improving the overall aesthetics and perception of the front of the vehicle.

[0074] Based on the continuous bending shape of the side mounting bracket 4 cross section, by setting a large number of structural weakening holes on the connecting plate 41 and the naval cover mounting platform 42, as well as the break 44 set on the naval cover mounting platform 42, when a collision occurs with a pedestrian's head, the impact force transmitted downward from the fender body 1 reaches the aforementioned crumple structure position. The crumple structure can cause the side mounting bracket 4 to bend and deform as a whole and crumple, thereby causing the fender body 1 to collapse, thus absorbing the energy of the collision injury and improving the safety of pedestrian protection.

[0075] The entire fender assembly is made of carbon fiber, which meets the requirements for high drop depth forming and satisfies the forming requirements of complex fender shapes (such as complex fenders in sports cars); it can also reduce the number of processes and reduce development costs; and it is conducive to achieving the appearance requirements of carbon fiber texture on the fender body 1.

[0076] Three support frames 5 are spaced apart along the longitudinal direction of the vehicle on the inner side of the fender body 1. Each support frame 5 provides support for the fender body 1 in the lateral direction of the vehicle. The support frames 5 are bonded to the fender body 1. Figures 7 to 9 As shown, the cross-sections of each support frame 5 and the fender body 1 on the YZ plane of the vehicle are all closed sections. On the one hand, this ensures that the fender assembly has a certain rigidity while meeting the requirements of vehicle safety and pedestrian protection, so that the fender assembly has a certain anti-dent stiffness and stability in non-collision scenarios. On the other hand, the setting of the support frame 5 is equivalent to increasing the force transmission path in the Y direction of the vehicle, thereby improving the side impact performance of the vehicle body.

[0077] Overall, this technical solution designs a front fender assembly for the vehicle body that offers high pedestrian protection performance, reduces the number of parts, and...

[0078] In summary, the fender assembly of this embodiment, by integrally molding a mounting bracket at the edge of the fender body 1 for mounting and fixing the fender body 1 on the vehicle body, reduces the number of structural components such as fender mounting brackets and fender reinforcing plates, thereby improving the integration and minimization of the fender assembly design. The use of carbon fiber for integral molding of the fender body 1 and the mounting bracket significantly enhances the lightweight design of the fender assembly. Furthermore, a crumple zone structure is provided on the side mounting bracket 4 located inside the fender body 1. In the event of a pedestrian collision at the front of the vehicle, when the pedestrian's head or upper body impacts the fender body 1, the crumple zone structure guides the fender body 1 to collapse inward, improving the cushioning effect and reducing the severity of injury to the pedestrian. This improves the safety performance of the fender assembly in pedestrian collisions.

[0079] An embodiment of the second aspect of this application provides a vehicle equipped with the fender assembly provided in Embodiment 1, and thus possesses the technical advantages of the aforementioned fender assembly.

[0080] By adopting the fender assembly of this application at the front of the vehicle, an integrated and fewer-parts design is achieved, which helps to reduce the number of processes and development costs; the crumple structure on the side mounting bracket 4 can improve the crumple energy absorption effect of the fender assembly in the event of a pedestrian collision at the front of the vehicle, thereby improving the level of pedestrian protection.

[0081] Furthermore, three support frames 5 are spaced apart along the longitudinal direction of the vehicle on the inner side of the fender body 1. Each support frame 5 provides support for the fender body 1 in the lateral direction of the vehicle. The support frames 5 are bonded to the fender body 1. Figures 7 to 9 As shown, the cross-sections of each support frame 5 and the fender body 1 on the YZ plane of the vehicle are all closed sections. On the one hand, this ensures that the fender assembly has a certain rigidity while meeting the requirements of vehicle safety and pedestrian protection, so that the fender assembly has a certain anti-dent stiffness and stability in non-collision scenarios. On the other hand, the setting of the support frame 5 is equivalent to increasing the force transmission path in the Y direction of the vehicle, thereby improving the side impact performance of the vehicle body.

[0082] Meanwhile, the entire fender assembly is made of carbon fiber, which improves the lightweight design level of the fender assembly, meets the requirements of high drop depth forming, meets the forming requirements of complex fender shapes (such as complex fender shapes in sports cars), and can reduce the number of processes and reduce development costs; and facilitates the realization of the appearance requirements of carbon fiber texture on the fender body 1.
