Description

Technical Field

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

[0002] The fender is the outer body panel that covers the wheels. Its function is to shield the vehicle body and prevent foreign objects such as stones kicked up by the tires from entering the vehicle. As a key area for pedestrian safety, the fender needs to meet safety requirements while also ensuring a certain level of rigidity and stability.

[0003] With the diversification of car styling, fenders now often need to provide mounting points for structures such as headlights, hoods, and bumpers. This requires fenders to have better rigidity to avoid assembly deformation. At the same time, fenders need to meet multiple requirements such as safety and refined feel.

[0004] Currently, fenders are mostly fixed to the vehicle body frame, such as the front wheel arch side beam, using mounting brackets. However, existing mounting brackets mainly consider the strength of the fender to resist external forces applied from the side of the vehicle, while neglecting the protection of pedestrians and failing to balance rigidity performance and safety. Utility Model Content

[0005] The purpose of this application is to provide a fender connection structure and vehicle that aims to improve energy absorption capacity while ensuring the installation strength of the fender.

[0006] To achieve the above objectives, in a first aspect, embodiments of this application provide a fender connection structure, comprising: Vehicle body frame; Fender, the fender is connected to the body frame, and an accommodating space is formed between the fender and the body frame; A support assembly is disposed within the accommodating space. The support assembly includes a fender reinforcement plate, a front fender bracket, and a connecting frame. The fender reinforcement plate is attached to the inner side of the fender. The front fender bracket connects the upper end of the vehicle frame and the fender reinforcement plate. The connecting frame connects the lower end of the vehicle frame and the fender reinforcement plate. The front fender support has a bending section, and the front fender support deforms along the bending section under stress.

[0007] The beneficial effects of the fender connection structure provided in this application are as follows: Compared with the prior art, the support components of the fender connection structure of this application include three parts. The fender reinforcing plate is attached to the fender and is inclined inwards from bottom to top, forming a first load-bearing structure. The front fender bracket connects the upper end of the vehicle frame and the fender reinforcing plate, as well as the upper edge of the fender, and is inclined outwards from bottom to top, forming a second load-bearing structure. The front fender support, as the second load-bearing structure, is mainly used for force transmission in the Z-direction, ensuring the fender's anti-dent stiffness requirements in the Z-direction. The connecting frame connects the lower end of the vehicle frame and the fender reinforcing plate, forming a laterally extending third load-bearing structure. The connecting frame, as the third load-bearing structure, is mainly used for force transmission in the Y-direction, ensuring the fender's anti-dent stiffness requirements in the Y-direction.

[0008] A bend is provided on the front fender support, with the opening of the bend facing horizontally, i.e., on the plane containing the XY axes. When the fender is under stress, the fender reinforcement plate presses against the front fender support. When the front fender support is subjected to longitudinal force, it will bend and deform along the bend, achieving an energy absorption effect.

[0009] The fender connection structure provided in this application has a fender reinforcing plate attached to the inner wall of the fender to balance the force on the fender and avoid localized force concentration. The triangular support component is located between the vehicle frame and the fender, improving the stiffness and stability of the fender. The front fender bracket is inclined longitudinally and has a bending section to achieve Z-axis bending energy absorption, thereby weakening the localized support structure, satisfying the energy absorption effect, and improving pedestrian safety performance. It balances the stiffness and safety of the fender structure.

[0010] In one possible implementation, the front fender bracket includes: An energy-absorbing hole is provided on the front support of the fender, and the two ends of the energy-absorbing hole extend to both sides of the bend in the longitudinal direction.

[0011] In the above technical solution, the energy-absorbing holes can weaken the support strength of the front fender bracket; the energy-absorbing holes cover the bend in the length direction, which weakens the support strength of the bend and improves the energy absorption effect.

[0012] In one possible implementation, the front fender bracket includes: Multiple support members are connected in sequence. Each support member has multiple mounting positions along the Y and Z directions at its end. The mounting positions are used to connect adjacent support members. The energy-absorbing hole and the bending portion are located on the uppermost support member.

[0013] In the above technical solution, each support member has multiple mounting positions along the horizontal and vertical directions, that is, multiple mounting positions in both the Y and Z directions. During installation, the connection position of the support member can be adjusted by switching different mounting positions to achieve fine-tuning in the Y and Z directions; thereby meeting the position adjustment needs of the fender along the Y and Z directions.

[0014] By arranging energy-absorbing structures such as energy-absorbing holes and bends on the support components closest to the fenders, the energy absorption effect can be maximized; this also allows the front fender support to form a structure with energy absorption at the top and support at the bottom, reducing damage to the vehicle body frame.

[0015] In one possible implementation, the front fender bracket includes: The first support member is connected to the fender reinforcement plate, and the energy-absorbing hole and the bending part are both located on the first support member; The second support member connects the lower end of the vehicle body frame and the first support member; the second support member is provided with a transverse section and a longitudinal section arranged at an angle, the transverse section is connected to the vehicle body frame, and the longitudinal section overlaps with the end of the first support member along the X direction.

[0016] In the above technical solution, the longitudinal section of the second support member is located in the plane where the YZ axis is located, and the end face of the longitudinal section faces the X direction; the longitudinal section and the second mounting part of the first support member are superimposed and fixed along the X direction, which increases the contact area of ​​the connection point between the first support member and the second support member, improves the connection stability, and thus ensures the support strength of the front bracket of the fender.

[0017] In one possible implementation, the second support member further includes: Several first reinforcing structures are provided at the connection between the longitudinal segment and the transverse segment; Several second reinforcing structures are disposed in the width direction of the second support member, and the second reinforcing structures are located on the side of the second support member away from the first support member.

[0018] In the above technical solution, a first reinforcing structure is provided at the bend of the second support member, which can improve the stiffness of the bend and enhance its resistance to deformation. The second reinforcing structure is used to increase the thickness of the second support member, thereby improving the overall stiffness of the second support member.

[0019] In one possible implementation, the connecting frame extends along the Y direction and includes multiple connecting plates connected in sequence. The ends of the connecting plates are provided with multiple connecting positions along both the X and Y directions, and the connecting positions are used to connect adjacent connecting plates.

[0020] In the above technical solution, the connecting plate can be fixed at different connection points during installation to change its position in the X and Y directions, thereby adjusting the lower part of the fender in the X and Y directions and improving the positional accuracy of the fender. The connecting plate is fixed by longitudinal overlapping, which increases the thickness at the connection point and improves the support strength along the length direction.

[0021] In one possible implementation, the connecting frame includes: A first connecting plate is provided with a longitudinal mounting surface, which is attached to the inner side of the fender reinforcement plate and connected to the fender reinforcement plate. The lower end of the fender reinforcement plate is provided with multiple fixing positions along the X and Z directions, and the longitudinal mounting surface is connected to any of the fixing positions.

[0022] In the above technical solution, the longitudinal mounting surface is attached to the fender reinforcement plate, increasing the local thickness of the lower part of the fender reinforcement plate. The longitudinal portion of the first connecting part and the fender reinforcement plate form an integral support structure. A mounting hole corresponding to the fender reinforcement plate is provided on the longitudinal mounting surface. This mounting hole is used to install the above-mentioned accessories, improving the safety and stability of the accessories.

[0023] The fender reinforcement plate has multiple fixing positions along the X-axis and multiple fixing positions along the Z-axis, with the fixing positions being bolt holes. Bolts on the longitudinal mounting surface can be locked through at least one bolt hole in a fixing position on the fender reinforcement plate. This arrangement of multiple fixing positions allows the fender reinforcement plate to be adjusted in the X and Z directions by selecting different fixing positions, thereby enabling fender adjustment.

[0024] The three adjustable connection points—mounting position, connection position, and fixing position—work together to allow the fender to be adjusted in the X, Y, and Z directions of the vehicle body. This ensures that the fender, along with other components such as the headlights, hood, and front bumper, meets the adjustment requirements of the Dimensional Technical Specification (DTS), guaranteeing vehicle body precision and enhancing the sense of refinement.

[0025] In one possible implementation, the connecting frame includes: The second connecting plate is used to connect the vehicle body frame; The second connecting plate has a mounting flange structure on the side near the vehicle frame, and the two sides of the second connecting plate in the width direction have reinforcing parts.

[0026] In the above technical solution, the mounting flange structure on the second reinforcing plate increases the contact area with the vehicle frame, improves installation stability, and avoids local stress on the vehicle frame; the setting of the reinforcing part increases the rigidity of the connecting frame on the side close to the vehicle frame.

[0027] In one possible implementation, the vehicle body frame includes: The side panel connecting plate is located on the outside of the front wheel arch side beam. The side panel connecting plate includes a horizontal mounting surface and a vertical mounting surface that are vertically connected. The front fender bracket is connected to the horizontal mounting surface, and the connecting frame is connected to the vertical mounting surface.

[0028] In the above technical solution, under the action of the side panel connecting plate, the fender front bracket, connecting frame and fender reinforcing plate form a triangular support structure, which ensures the support stability of the fender; the fender front bracket and connecting frame are installed on different mounting surfaces. The fender front bracket forms a longitudinal force transmission channel with respect to the horizontal mounting surface of the side panel connecting plate, and the connecting frame forms a transverse force transmission channel with respect to the vertical mounting surface, thus dispersing the stress points of the side panel connecting plate and avoiding stress concentration.

[0029] Secondly, embodiments of this application also provide a vehicle including the aforementioned fender connection structure.

[0030] In the above technical solution, a triangular support component is set between the fender and the body frame. Energy absorption in the Z direction is achieved by setting energy-absorbing structures such as bending parts on the front support of the fender, thereby weakening the support structure locally to meet the energy absorption effect. The rigidity, stability and safety of the fender are taken into account, thereby improving the overall stability and comfort of the vehicle. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0036] 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.

[0037] Please refer to the following: Figures 1 to 6 The fender connection structure provided in this application is described below. The fender connection structure includes a vehicle frame 1, a fender 2, and a support assembly. The fender 2 is connected to the vehicle frame 1, forming an accommodating space between the fender 2 and the vehicle frame 1. The support assembly is located within the accommodating space and includes a fender reinforcing plate 3, a front fender bracket 4, and a connecting frame 5. The fender reinforcing plate 3 is attached to the inner side of the fender 2. The front fender bracket 4 connects the upper ends of the vehicle frame 1 and the fender reinforcing plate 3. The connecting frame 5 connects the lower ends of the vehicle frame 1 and the fender reinforcing plate 3. The front fender bracket 4 has a bending portion 41, which deforms along the bending portion 41 under stress.

[0038] Currently, to address the issue of fender 2 easily denting under stress, a common approach is to add a support structure to the inner side of fender 2 to ensure it has sufficient strength to withstand external forces applied from the side of the vehicle. However, existing support structures are mostly L-shaped plate structures, with one end connected to the vehicle frame 1 and the other end connected to the inner side of fender 2. While this increases the rigidity of fender 2, it neglects pedestrian protection, resulting in insufficient energy absorption by the fender 2 structure and posing a significant hazard in the area of ​​collision with a pedestrian.

[0039] To balance the rigidity and energy absorption effect of fender 2, a support assembly is proposed to be installed in the space between the body frame 1 and fender 2. The support assembly consists of three parts: a fender reinforcement plate 3 that fits against fender 2 and is inclined inwards from bottom to top, forming the first load-bearing structure; a front fender bracket 4 that connects the upper ends of the body frame 1 and fender reinforcement plate 3, as well as the upper edge of fender 2, and is inclined outwards from bottom to top, forming the second load-bearing structure; and a front support for fender 2, serving as the second load-bearing structure, primarily for force transmission in the Z-direction, ensuring the fender 2's anti-dent stiffness requirements in the Z-direction; and a connecting frame 5 that connects the lower ends of the body frame 1 and fender reinforcement plate 3, forming a laterally extending third load-bearing structure. The connecting frame 5, as the third load-bearing structure, primarily for force transmission in the Y-direction, ensuring the fender 2's anti-dent stiffness requirements in the Y-direction.

[0040] It is worth noting that the fender 2 is located on the outside of the body frame 1. The aforementioned fender reinforcement plate 3 tilts inward toward the side closer to the body frame 1, and the corresponding fender front bracket 4 tilts outward toward the side closer to the fender 2.

[0041] The aforementioned first, second, and third load-bearing structures are sequentially connected to form a triangular support assembly, ensuring the fender 2 is stably mounted on the outer side of the vehicle frame 1. The first load-bearing structure adheres to the inner wall of the fender 2, and when the fender 2 is impacted by an external force, the fender 2 promptly transmits the force to the first load-bearing structure. The fender reinforcement plate 3, acting as the first load-bearing structure, promptly and evenly transmits the force received to its upper and lower ends, and then to the second and third load-bearing structures, which in turn transmit the force to the vehicle frame 1. The fender reinforcement plate 3 evenly distributes the force and, with the help of the fender front bracket 4 and connecting frame 5, transmits the force to the vehicle frame 1, avoiding localized force concentration on the fender 2, reducing the degree of damage to the fender 2, and simultaneously reducing the impact of the impact on core areas such as the cockpit, thus improving safety.

[0042] A bending section 41 is provided on the front fender support 4, with the opening of the bending section 41 facing the horizontal direction, i.e., the plane where the XY axis is located. When the fender 2 is under force, the fender reinforcing plate 3 compresses the front fender support 4. When the front fender support 4 is subjected to longitudinal partial pressure, it will bend and deform along the bending section 41, achieving the effect of energy absorption.

[0043] The fender connection structure provided in this application has the following advantages compared with the prior art: (1) The fender reinforcement plate 3 is attached to the inner wall of the fender 2 to balance the force on the fender 2 and avoid local force concentration on the fender 2.

[0044] (2) The fender reinforcement plate 3, the fender front bracket 4 and the connecting frame 5 cooperate to form a triangular support assembly. The triangular support assembly is located between the vehicle frame 1 and the fender 2 to support the fender 2, ensuring that the force on the fender 2 is evenly transmitted to the vehicle frame 1, thereby improving the rigidity and stability of the fender 2; thus improving the overall stability and comfort of the vehicle; at the same time, it provides a stable fixed reference for the fender 2, preventing the fender 2 from shifting due to vibration during vehicle operation.

[0045] (3) The front support 4 of the fender is inclined along the longitudinal direction and a bending part 41 is provided on the front support 4 of the fender; when the fender 2 is impacted, the bending part 41 of the front support 4 of the fender first undergoes bending deformation, realizing bending energy absorption in the Z direction, realizing local weakening of the support structure, satisfying the energy absorption effect, and improving pedestrian safety performance; taking into account both the rigidity performance and safety of the fender 2 structure.

[0046] Optionally, the front fender support 4 may be provided with multiple bends 41, with adjacent bends 41 spaced longitudinally apart. Taking a front fender support 4 with two bends 41 as an example, the front fender support 4 may have a Z-shaped structure, with flange mounting portions at both ends. The lower flange mounting portion is connected to the vehicle frame 1, and the upper flange mounting portion is connected to the fender reinforcement plate 3. Under stress, the front fender support 4 uses the bends 41 to form a continuous Z-shaped bending force transmission, thereby weakening the local support force and achieving energy absorption.

[0047] In some embodiments, the aforementioned front fender bracket 4 can be adopted as follows: Figure 1 , Figure 2 and Figure 4 The structure shown is as follows. The front fender bracket 4 includes an energy-absorbing hole 42, which is formed on the front fender bracket 4. The two ends of the energy-absorbing hole 42 extend to both sides of the bent portion 41 in the longitudinal direction.

[0048] The energy-absorbing hole 42 is an elongated hole, and its length direction is consistent with the length direction of the front fender support 4, and the energy-absorbing hole 42 covers the bend 41 in the length direction. The energy-absorbing hole 42 can weaken the supporting strength of the front fender support 4; the energy-absorbing hole 42 covers the bend 41 in the length direction, which weakens the supporting strength of the bend 41 and improves the energy absorption effect.

[0049] When the fender 2 is subjected to force, the part where the energy absorption hole 42 is located is the preset weak point of the support force and deforms first. It consumes part of the impact energy through its own deformation, achieving a buffering effect and preventing the impact force from being directly transmitted to the body frame 1, thereby reducing the damage to the fender 2 and the body frame 1.

[0050] As the main load-bearing structure in the Z direction, the energy-absorbing holes 42 of the front fender bracket 4, together with the bending part 41, can cause the front fender bracket 4 to deform first when the fender 2 is under stress. This prevents the front fender bracket 4 from being too rigidly stressed and thus causing it to break or shift, thereby preventing the front fender bracket 4 from affecting the fender 2 and other surrounding components.

[0051] In addition, the energy-absorbing hole 42 can also reduce the weight of the front fender bracket 4, thus achieving the purpose of weight reduction.

[0052] The energy-absorbing hole 42 can be a rectangular hole or an oblong hole, and the extension length of the energy-absorbing hole 42 on both sides of the bend 41 is the same. The centerline of the energy-absorbing hole 42 in the width direction coincides with the centerline of the width direction of the fender front support 4, that is, the structural width on both sides of the energy-absorbing hole 42 is the same, so as to ensure that the fender front support 4 can bend completely along the fold line of the bend 41 when subjected to force.

[0053] In some embodiments, the front fender bracket 4 includes multiple support members connected in sequence. The ends of the support members are provided with multiple mounting positions along the Y and Z directions, and the mounting positions are used to connect adjacent support members. The energy absorption hole 42 and the bending portion 41 are provided on the uppermost support member.

[0054] Any two support members are located in the plane of the XZ direction, and adjacent support members overlap along the X direction and are fixed by fasteners. Each support member has multiple mounting positions along the horizontal and vertical directions, that is, multiple mounting positions in both the Y and Z directions. During installation, the connection position of the support member can be adjusted by switching different mounting positions to achieve fine-tuning in the Y and Z directions.

[0055] The sequential connection of multiple support components allows the fender front bracket 4 to change its mounting point by altering the overlap length and position of any two support components, thereby adjusting the position of the fender 2 in the Y and Z directions. For example, the support components are secured with bolts after overlapping. Multiple bolt holes are provided at the ends of the support components along both the Y and Z directions. When connecting adjacent support components, the connection position can be changed by selecting different bolt holes along the Y or Z directions, thus adjusting the position of the fender 2 in the Y and Z directions.

[0056] Optionally, two or three support members can be selected. During installation, multiple bolt holes are drilled at the overlapping positions of the support members, and they are fixed with bolts. During installation, the height and Y-axis position of the support members can be changed according to the matching method of the bolt holes of two adjacent support members, thereby changing the specific position of the fender 2 in the Y and Z directions.

[0057] Energy-absorbing holes 42 and bending portions 41 are located on the uppermost support member, which is connected to the fender 2. When the fender 2 is under stress, the force is first transmitted from the fender 2 to the uppermost support member. By arranging energy-absorbing structures such as energy-absorbing holes 42 and bending portions 41 on the support member closest to the fender 2, the energy absorption effect can be maximized. After the pressure passes through the energy-absorbing structure, part of the pressure is absorbed, and the remaining part continues to be transmitted downwards along the lower support member to the body frame 1. Ultimately, the force transmitted to the body frame 1 is reduced, thereby reducing damage to the body frame 1.

[0058] In one embodiment, such as Figures 1 to 5 As shown, the front fender bracket 4 includes a first support member 45 and a second support member 46; the first support member 45 is connected to the fender reinforcing plate 3, and the energy absorption hole 42 and the bending part 41 are both located on the first support member 45; the second support member 46 connects the body frame 1 and the lower end of the first support member 45; the upper end of the second support member 46 and the lower end of the first support member 45 overlap along the X-axis direction and are fixed by means of a fastener.

[0059] The front fender bracket 4 is divided into two parts. The first support member 45 serves as the main energy-absorbing structure and is located on the side close to the fender 2. The second support member 46 serves as the main support structure and is located on the side close to the body frame 1.

[0060] Specifically, the first support member 45 of the fender front bracket 4 is a Z-shaped plate structure. The first support member 45 includes a first mounting part 43, a second mounting part 44, and a support member body. The support member body has two spaced-apart bends 41, and the openings of the bends 41 face the same side of the support member body. The two ends of the support member body along its length form the first mounting part 43 and the second mounting part 44 respectively by flanges. The first mounting part 43 is located at the upper end of the support member body, and is arranged laterally and fits against the upper flange of the fender 2. The first mounting part 43 overlaps with the fender 2 and the fender reinforcing plate 3 and is fixed by bolts. The second mounting part 44 is located at the lower end of the support member body, and is arranged longitudinally and overlaps with the upper end of the second support member 46 and is connected by a fastener. The fastener can be a bolt, a clip, a pin, etc.

[0061] The first mounting portion 43 can be formed by bending the support body, and the bend between the first mounting portion 43 and the support body also has an energy-absorbing effect. Similarly, the second mounting portion 44 can be formed by bending the support body, and the bend between the second mounting portion 44 and the support body also has an energy-absorbing effect.

[0062] The first mounting part 43 has multiple bolt holes, and similarly, the fender 2 and the fender reinforcing plate 3 also have multiple bolt holes. The first mounting part 43 is fixed to the fender 2 and the fender reinforcing plate 3 by bolts after overlapping. The fender 2 can be adjusted along the X and Y directions using the bolt holes on the first mounting part 43. The first mounting part 43 has multiple bolt holes along both the Y and X directions. During installation, by selecting different bolt hole positions, the relative position of the fender 2 and the first mounting part 43 can be changed, thus achieving adjustment of the fender 2.

[0063] The second mounting part 44 is fixedly connected to the vehicle body frame 1 to increase the support stability of the second mounting part 44. The second mounting part 44 and the vehicle body frame 1 can be fixed by welding or riveting.

[0064] like Figure 5 As shown, the second support member 46 includes a transverse section and a longitudinal section. The transverse section is connected to the vehicle frame 1. The longitudinal section is set at an angle to the transverse section, and the longitudinal section connects the transverse section and the first support member 45.

[0065] The second support member 46 is an L-shaped or V-shaped plate structure. The second support member 46 is bent from the middle to form a transverse section and a longitudinal section. The transverse section is located in the plane containing the XY axis and fits against a mounting surface of the vehicle frame 1. The transverse section is welded to the mounting surface of the vehicle frame 1. The longitudinal section extends upward, and the free end of the longitudinal section overlaps with the first support member 45 and is fixed by bolts.

[0066] When the second support member 46 is bent, the longitudinal section is positioned within the plane containing the YZ axis, with the end face of the longitudinal section facing the X direction. The longitudinal section and the second mounting portion 44 of the first support member 45 are superimposed and fixed along the X direction, increasing the contact area at the connection point between the first support member 45 and the second support member 46, improving connection stability, and thus ensuring the support strength of the fender front bracket 4.

[0067] In addition, multiple bolt holes are provided at the ends of the longitudinal section and the second mounting part 44. The fender 2 can be adjusted in the Y and Z directions by selecting and adjusting the bolt holes.

[0068] In one embodiment, such as Figure 5 As shown, the second support member 46 further includes a plurality of first reinforcing structures 47 and a plurality of second reinforcing structures 48. The plurality of first reinforcing structures 47 are disposed at the connection between the longitudinal segment and the transverse segment; the plurality of second reinforcing structures 48 are disposed in the width direction of the second support member 46, and the second reinforcing structures 48 are located on the side of the second support member 46 away from the first support member 45.

[0069] The second support member 46 serves as the main support structure. A first reinforcing structure 47 is provided at the bend of the second support member 46 to improve its rigidity, enhance its resistance to deformation, and prevent bending at the bend. The first reinforcing structure 47 can be a structural rib, protruding from the inside of the bend. Multiple first reinforcing structures 47 can be provided, spaced apart along the width direction of the second support member 46.

[0070] The second mounting portion 44 of the first support member 45 is attached to the outer side of the bent portion of the second support member 46. A second reinforcing structure 48 is distributed on the inner side of the bent portion of the second support member 46, and the length of the second reinforcing structure 48 is the same as the length of the second support member 46. The second reinforcing structure 48 is used to increase the thickness of the second support member 46, thereby improving the rigidity of the second support member 46 and preventing it from bending under stress.

[0071] The second reinforcing structure 48 can be a structural rib or a flange structure. For example... Figure 3 and Figure 5 As shown, the second reinforcing structure 48 is a flange structure symmetrically arranged on two edges of the second support member 46 in the width direction. The extension direction of the flange structure is perpendicular to the second support member 46. Both edges of the second support member 46 in the width direction are provided with flange structures of the same width to ensure that the support strength of the second support member 46 is consistent in the width direction and to avoid uneven local stress.

[0072] In some embodiments, such as Figure 6As shown, the connecting frame 5 extends along the Y direction and includes multiple connecting plates connected in sequence. The ends of the connecting plates are provided with multiple connecting positions along the X and Y directions, and the connecting positions are used to connect adjacent connecting plates.

[0073] The connecting frame 5 includes multiple connecting plates connected horizontally in sequence. The ends of two adjacent connecting plates overlap along the Z-direction. When connecting two adjacent connecting plates, any connection position can be selected for fixing to form a connection point. The connecting plates are fixed by longitudinal overlap, which can increase the thickness at the connection point and improve the support strength along the length direction.

[0074] Due to the distribution of multiple connection points, the connection plate can be fixed by selecting different connection points during installation to change the position of the connection plate in the X and Y directions, thereby adjusting the position of the lower part of the fender 2 in the X and Y directions and improving the positional accuracy of the fender 2.

[0075] Optionally, adjacent connecting plates can be fixed with bolts. In this case, both ends of the connecting plates have connecting portions with multiple bolt holes forming multiple connection points. During installation, at least one bolt hole is aligned with a bolt hole on an adjacent connecting plate, and then fixed with bolts.

[0076] In some embodiments, such as Figure 6 As shown, the connecting frame 5 includes a first connecting plate 51, which has a longitudinal mounting surface. The longitudinal mounting surface is attached to the inner side of the fender reinforcing plate 3 and connected to the fender reinforcing plate 3. The lower end of the fender reinforcing plate 3 has multiple fixing positions along the X and Z directions, and the longitudinal mounting surface is connected to any of the fixing positions.

[0077] The connecting plate 5 used to connect the fender reinforcement plate 3 is the first connecting plate 51. The first connecting plate 51 includes two parts: one part extends longitudinally to connect the fender reinforcement plate 3 and improve its connection strength; the other part extends laterally to connect other connecting plates.

[0078] The first connecting plate 51 has a longitudinal mounting surface on the side near the fender reinforcement plate 3. This longitudinal mounting surface is attached to the fender reinforcement plate 3, increasing the local thickness of the lower part of the fender reinforcement plate 3. Since the lower part of the fender reinforcement plate 3 serves as a support structure for mounting accessories such as headlights, hood, and front bumper, the attachment of the longitudinal mounting surface of the first connecting plate 51 to the fender reinforcement plate 3 increases the thickness of the lower part of the fender reinforcement plate 3, thereby improving the support strength of the fender reinforcement plate 3.

[0079] The longitudinal portion of the first connecting plate 51 and the fender reinforcing plate 3 form an integral support structure. Mounting holes 53 corresponding to the fender reinforcing plate 3 are provided on the longitudinal mounting surface. These mounting holes 53 are used to install the aforementioned accessories, thereby improving the safety and stability of the accessories.

[0080] Bolts for connecting the fender reinforcement plate 3 are also provided on the longitudinal mounting surface. The corresponding fender reinforcement plate 3 has multiple fixing positions along the X-axis and multiple fixing positions along the Z-axis, with the fixing positions being bolt holes. The bolts on the longitudinal mounting surface can lock at least one bolt hole in a fixing position on the fender reinforcement plate 3. This arrangement of multiple fixing positions allows the fender reinforcement plate 3 to be adjusted in the X and Z directions by selecting different fixing positions, thereby adjusting the fender 2.

[0081] The multiple mounting positions allow for adjustment of the fender 2 in the Y and Z directions, the multiple connection positions allow for adjustment in the X and Y directions, and the multiple fixed positions allow for adjustment in the X and Z directions. The coordinated use of these three adjustable connection points enables the fender 2 to be adjusted in all three dimensions of the vehicle body: X, Y, and Z. This ensures that the fender 2, along with other components such as the headlights, hood, and front bumper, meets the adjustment requirements of the Dimensional Technical Specification (DTS), guaranteeing vehicle body precision and enhancing the sense of refinement.

[0082] In some embodiments, such as Figure 6 As shown, the connecting frame 5 also includes a second connecting plate 52, which is used to connect the vehicle body frame 1; the second connecting plate 52 has a mounting flange structure 54 on the side near the vehicle body frame 1, and the two sides of the second connecting plate 52 in the width direction have reinforcing parts.

[0083] The connecting plate of the connecting bracket 5 near the body frame 1 is the second connecting plate 52. The side of the second connecting plate 52 near the body frame 1 is provided with a mounting flange structure 54, which is attached to the mounting surface of the body frame 1. The mounting flange structure 54 is welded or bolted to the body frame 1.

[0084] To improve the rigidity of the connecting frame 5 near the vehicle body frame 1, a reinforcing part is provided on the second connecting plate 52 where the flange structure 54 is installed. The reinforcing part can be a folded edge. A first folded edge is provided on both edges in the width direction of the second connecting plate 52, and a second folded edge is provided on both edges in the width direction of the flange structure 54. The first and second folded edges are welded and fixed to form an L-shaped reinforcing structure.

[0085] The connecting frame 5 may consist only of a first connecting plate 51 and a second connecting plate 52. Both the first connecting plate 51 and the second connecting plate 52 have weight-reduction holes.

[0086] In some embodiments, such as Figure 1 As shown, the vehicle body frame 1 includes a side panel connecting plate 11, which is located on the outside of the front wheel arch side beam. The side panel connecting plate 11 includes a horizontal mounting surface and a vertical mounting surface that are vertically connected. The fender front bracket 4 is connected to the horizontal mounting surface, and the connecting bracket 5 is connected to the vertical mounting surface.

[0087] The side panel connecting plate 11 is set around the outside of the front wheel arch side beam. The fender front bracket 4 and the connecting frame 5 are both installed on the side panel connecting plate 11. Although the mounting surfaces are not on the same plane, under the action of the side panel connecting plate 11, the fender front bracket 4, the connecting frame 5 and the fender reinforcing plate 3 form a triangular support structure.

[0088] In addition, the front fender bracket 4 and the connecting bracket 5 are installed on different mounting surfaces. The front fender bracket 4 forms a longitudinal force transmission channel for the horizontal mounting surface of the side panel connecting plate 11, and the connecting bracket 5 forms a transverse force transmission channel for the vertical mounting surface, thereby dispersing the force points of the side panel connecting plate 11 and avoiding force concentration.

[0089] Based on the same inventive concept, this application also provides a vehicle including the above-described fender connection structure.

[0090] Compared with the prior art, the fender connection structure provided in this application has the following advantages: a triangular support component is set between the fender 2 and the body frame 1, and energy absorption in the Z direction is achieved by setting energy absorption structures such as the bending part 41 on the front support 4 of the fender, thereby achieving local weakening of the support structure to meet the energy absorption effect; the rigidity, stability and safety of the fender 2 are taken into account, thereby improving the overall stability and comfort of the vehicle.

[0091] 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.
