Description

Technical Field

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

[0002] The fender is the outer body panel that covers the wheels. Fenders are usually fixed to the longitudinal beams of the vehicle's engine compartment via connecting brackets; therefore, the rigidity, connection strength, and torsional resistance of the connecting brackets directly affect the installation performance of the fender.

[0003] In the existing technology, the cantilever structure of the fender mounting bracket is relatively long. During long-term vehicle operation, the fender is prone to deformation under the action of bump loads, and even sheet metal cracking may occur, affecting the appearance and overall performance of the vehicle. Utility Model Content

[0004] The purpose of this application is to provide a fender connection bracket and a vehicle, aiming to solve the technical problems of poor resistance to bump loads and easy deformation and cracking of existing fender mounting bracket structures.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, a fender connection bracket is provided, comprising: A connecting beam assembly extends along the left and right direction of the vehicle body; the outer side of the connecting beam assembly along the left and right direction is used for fixed connection with the fender, and the inner side is used for fixed to the longitudinal beam of the engine compartment. A support frame is provided on one side of the connecting beam assembly along the front-rear direction of the vehicle body and extends along the left-right direction of the vehicle body; the inner and outer extensions of the support frame are formed on the inner and outer sides along the left-right direction, the outer extension is fixedly connected to the connecting beam assembly, and the inner extension is connected to the engine compartment longitudinal beam. The connecting beam assembly has a U-shaped structure with its opening facing the cabin longitudinal beam, and the two ends of the opening side of the U-shaped structure are fixed to the cabin longitudinal beam at intervals; the outer extension is connected to the connecting beam assembly through the U-shaped bottom of the U-shaped structure.

[0006] Compared with the prior art, the solution shown in this application embodiment sets the connecting beam group as a U-shaped structure, and fixes both ends of the opening side of the U-shaped structure to the cabin longitudinal beam, so as to form two sets of connection points at both ends of the opening side of the U-shaped structure, thereby increasing the number of connection points between the inner side of the connecting beam group and the cabin longitudinal beam, which is beneficial to enhancing the connection strength between the connecting beam group and the cabin longitudinal beam. Furthermore, this application includes a support frame, which is connected to the cabin longitudinal beam via an inner extension and to the U-shaped bottom of the U-shaped structure via an outer extension, thereby achieving the connection between the support frame and the connecting beam assembly. Therefore, the support frame of this application can form a connecting bridge between the U-shaped bottom of the U-shaped structure and the cabin longitudinal beam, further improving the connection and support strength between the connecting beam assembly and the cabin longitudinal beam. Compared to the cantilever beam structure in traditional technology, the connecting beam group in this application forms two sets of connection points on the inner side through the two ends of the U-shape, and a set of connection reinforcement points on the outer side through the bottom of the U-shape. The inner connection points are directly fixed to the longitudinal beam of the engine compartment, and the outer reinforcement points are indirectly fixed to the longitudinal beam of the engine compartment through the support frame. This simultaneously enhances the connection and support strength of the connecting beam group in both the inner and outer directions, thereby improving the anti-bump load capacity of the support structure, which is conducive to improving the stability of the fender connection and support, avoiding deformation and cracking problems, and optimizing the overall vehicle performance.

[0007] In conjunction with the first aspect, in one possible implementation, the fender connecting bracket further includes: A reinforcing plate is provided on the inner side of the support frame; the upper end of the reinforcing plate is connected to the longitudinal beam of the cabin, and the lower end abuts against the inner extension. The inner extension extends downward through the longitudinal beam of the cabin; the reinforcing plate extends downward with the support frame, and multiple connecting bolts are provided vertically and vertically between the inner extension and the inner extension.

[0008] By setting a reinforcing plate, the connection strength between the inner side of the support frame and the longitudinal beam of the engine room can be improved. Specifically, one end of the support frame extends downward, and the reinforcing plate extends downward with the support frame, which can facilitate the installation of multiple connecting bolts. The multiple bolts are set at intervals between the upper and lower parts, which can increase the number of connection points between the reinforcing plate and the inner extension, thereby enhancing the connection strength between the support frame and the longitudinal beam of the engine room.

[0009] In some embodiments, the upper end of the inner extension is fixed to the outside of the cabin longitudinal beam; the upper end of the reinforcing plate is bent inward and abuts against the bottom of the cabin longitudinal beam, and is fixedly connected to the cabin longitudinal beam.

[0010] By bending the upper end of the reinforcing plate to fix it to the bottom of the cabin longitudinal beam, the inner extension can be connected to the bottom of the cabin longitudinal beam through the reinforcing plate. Since the upper end of the inner extension is also connected to the outer side of the cabin longitudinal beam, the inner extension in this application can form connection points on the outer side and bottom of the cabin longitudinal beam, which is beneficial to further enhance the connection strength between the support frame and the cabin longitudinal beam.

[0011] In conjunction with the first aspect, in one possible implementation, the portion of the support frame connecting the outer extension and the inner extension is defined as the main body; the main body is provided with a plurality of triangular cavities that extend from front to back, and the plurality of triangular cavities are spaced apart around the center of the main body to divide the main body into a plurality of triangular support structures.

[0012] The triangular support structure has good support stability. In this application, by setting triangular cavities to form multiple triangular support structures, it is beneficial to improve the support strength of the main body. Furthermore, the multiple triangular support structures are set around the center of the main body, which is beneficial to form an X-shaped support structure with the center of the main body as the support point, thereby improving the support strength of the main body.

[0013] In some embodiments, the support frame is provided with multiple reinforcing ribs, which are interlaced to form multiple support grids.

[0014] By setting multiple reinforcing ribs, the support strength of the support frame itself can be further improved; by forming multiple support grids through the interlacing of multiple reinforcing ribs, a grid support structure can be formed on the support frame to ensure the overall support stability of the support frame.

[0015] In conjunction with the first aspect, in one possible implementation, the fender connecting bracket further includes: The first connecting plate is connected to the support frame at one end and extends upward at the other end, and is fixed to the connecting beam assembly; The second connecting plate is spaced apart from the first connecting plate; one end of the second connecting plate is fixedly connected to the connecting beam assembly, and the other end is used to fix it to the fender.

[0016] The first connecting plate is used to connect the support frame and the connecting beam assembly; the second connecting plate is used to connect the connecting beam assembly and the fender. The first and second connecting plates can be used to compensate for the height gap between the connecting beam assembly and the support frame and the fender, thereby facilitating the intermediate connection and support functions of the connecting beam assembly.

[0017] In some embodiments, there are two second connecting plates, which are symmetrically distributed on the front and rear sides of the first connecting plate.

[0018] By symmetrically distributing the second connecting plates in front of and behind the first connecting plate, the symmetry of the fender connection in the front-rear direction can be achieved, which is beneficial to improving the uniformity of stress on the connecting beam group and improving the support stability of the connecting beam group.

[0019] In conjunction with the first aspect, in one possible implementation, the connecting beam assembly includes: The rear end beam is fixed at one end to the longitudinal beam of the cabin, and extends towards the fender at the other end. A front beam, spaced apart on the front side of the rear beam, and fixedly connected to the nacelle longitudinal beam; and The middle beam is connected at both ends to the front beam and the rear beam to form the U-shaped structure; the middle beam is connected to the fender and the support frame respectively.

[0020] By setting front and rear beams with spacing between them, two sets of connection points on the inner side of the connecting beam group are realized. By setting an intermediate beam, connection reinforcement points on the outer side of the connecting beam group are realized, and the front and rear beams are connected and fixed.

[0021] In some embodiments, one end of the intermediate beam is connected to the front beam, and the other end is bent downwards and extends; The extended end of the rear beam also bends downward and connects to the bent end of the intermediate beam.

[0022] By bending the other end of the middle beam downwards and extending it downwards, and bending the extension end of the rear beam downwards, it is beneficial to create clearance space at the extension end of the rear beam, avoiding interference between the connection between the rear beam and the middle beam and other internal structural components, and ensuring the independence and stability of the connecting beam group support.

[0023] Secondly, embodiments of this application also provide a vehicle that includes the aforementioned fender connecting bracket.

[0024] The vehicle provided in this application, having included the aforementioned fender connecting bracket, possesses all the beneficial effects of the aforementioned fender connecting bracket. It has high support and connection strength, which can improve the bracket structure's resistance to bump loads, improve the stability of the fender connection and support, thereby avoiding deformation and cracking problems and optimizing the overall performance of the vehicle.

[0028] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

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

[0030] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

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

[0032] In addition, the front-rear direction of the vehicle body as defined in the embodiments of this application refers to the front-rear direction of the vehicle's forward direction during driving, and the left-right direction of the vehicle body as defined in the embodiments of this application refers to the left-right direction of the vehicle's forward direction during driving. Furthermore, the inward and outward directions referred to in this application are all based on the inward and outward directions of the vehicle's left-right direction.

[0033] It is important to understand that a car has a first centerline extending along the direction of travel, and the first centerline is perpendicular to the left and right directions of the car body. The left side of the first centerline is the driver's side, and the right side is the passenger side. The directions defined by the first centerline can be understood as directions closer to or farther from the first centerline, that is, directions closer to the first centerline are inward, and directions farther from the first centerline are outward.

[0034] Additionally, it should be understood that the fender is the outer body panel that covers the wheels. Therefore, fenders and fender connecting brackets are provided at the wheels on both the left and right sides, and the fender connecting brackets on the left and right sides are often symmetrically arranged along the first center line.

[0035] In traditional technology, the upper bracket of the fender is usually installed by overlapping two bracket plates and then fixing them tightly together with the fender reinforcement plate 3 and the fender. However, the connection structure of the two bracket plates in this connection method is a cantilever structure, and the fender is fixed to the cantilever end of the cantilever structure. Therefore, under the action of bump load, the fender is prone to vertical displacement and deformation, or even cracking, which affects the aesthetics and stability of the whole vehicle.

[0036] The engine compartment longitudinal beam 6 is a structural component located below the front engine compartment of a car. As part of the vehicle frame, and the frame being the most important load-bearing component, the engine compartment longitudinal beam 6 plays a crucial load-bearing role. The engine compartment longitudinal beam 6 typically extends along the longitudinal direction of the vehicle body.

[0037] Please refer to the following: Figures 1 to 3 The fender connecting bracket and vehicle provided in this application will now be described. The fender connecting bracket includes a connecting beam assembly 1 and a support frame 2; the connecting beam assembly 1 extends along the left-right direction of the vehicle body; the outer side of the connecting beam assembly 1 along the left-right direction is used for fixed connection with the fender, and the inner side is used for fixed to the engine compartment longitudinal beam 6; the support frame 2 is located on one side of the connecting beam assembly 1 along the front-rear direction of the vehicle body and extends along the left-right direction of the vehicle body; the inner and outer sides of the support frame 2 along the left-right direction form an inner extension 22 and an outer extension 23 respectively, the outer extension 23 is fixedly connected to the connecting beam assembly 1, and the inner extension 22 is connected to the engine compartment longitudinal beam 6; wherein, the connecting beam assembly 1 has a U-shaped structure with the opening facing the engine compartment longitudinal beam 6, and the two ends of the opening side of the U-shaped structure are fixed to the engine compartment longitudinal beam 6 at a distance from front to back; the outer extension 23 is connected to the U-shaped bottom of the U-shaped structure.

[0038] Preferably, the U-shaped ends of the connecting beam assembly 1 on the open side are at the same height as the connection point of the engine compartment longitudinal beam 6, and are spaced apart in the front-rear direction of the vehicle body to avoid twisting deformation of the connecting beam assembly 1 in the front-rear direction.

[0039] It should be understood that the connecting beam group 1 in this application has a U-shaped structure and has two sets of direct connection points and one set of reinforcing points with the cabin longitudinal beam 6. Compared with the traditional cantilever structure, the fender connecting bracket in this application has better torsional resistance, can resist the effect of torsional deformation force, and has better stability.

[0040] Optionally, the U-shaped ends of the connecting beam assembly 1 on the open side are welded and fixed to the engine room longitudinal beam 6, i.e., connected to the engine room longitudinal beam 6 by welding wire. Optionally, the U-shaped ends of the connecting beam assembly 1 on the open side are connected to the engine room longitudinal beam 6 by fixing bolts or fixing screws.

[0041] Optionally, the inner side of the support frame 2 is fixed to the nacelle longitudinal beam 6 by fixing bolts or screws. Specifically, the inner extension 22 is fixed to the outer side or bottom of the nacelle longitudinal beam 6, or the inner extension 22 is fixed to the outer side and bottom of the nacelle longitudinal beam 6 respectively.

[0042] For example, the specific structure of the support frame 2 can be selectively configured according to actual needs.

[0043] The support frame 2 is located on one side of the connecting beam assembly 1 along the front-rear direction of the vehicle body. Optionally, the support frame 2 is located on the front side of the connecting beam assembly 1, and the inner extension 22 and the outer extension 23 are bent backward; or the support frame 2 is located on the rear side of the connecting beam assembly 1, and the inner extension 22 and the outer extension 23 are bent forward.

[0044] It should be understood that the inner and outer sides of the support frame 2 are bent to form an outer extension 23 and an inner extension 22. Optionally, both the inner and outer sides of the support frame 2 are bent forward to form an outer extension 23 and an inner extension 22. In this case, a U-shaped groove with an opening facing forward is formed between the inner extension 22, the outer extension 23 and the middle main body 21 of the support frame 2. Alternatively, both the inner and outer sides of the support frame 2 are bent backward to form an outer extension 23 and an inner extension 22. In this case, a U-shaped groove with an opening facing backward is formed between the inner extension 22, the outer extension 23 and the middle main body 21 of the support frame 2.

[0045] Optionally, the inner side of the support frame 2 is bent forward to form an inner extension 22, and the outer side of the support frame 2 is bent backward to form an outer extension 23. In this case, a first Z-shaped structure is formed between the inner extension 22, the outer extension 23, and the middle main body 21 of the support frame 2. Alternatively, the inner side of the support frame 2 can be bent backward to form an inner extension 22, and the outer side of the support frame 2 can be bent forward to form an outer extension 23. In this case, a second Z-shaped structure is formed between the inner extension 22, the outer extension 23, and the middle main body 21 of the support frame 2.

[0046] For example, the inner extension 22 can be disposed in the U-shaped opening of the connecting beam assembly 1 so that the connection point between the inner extension 22 and the cabin longitudinal beam 6 falls between the connection points at both ends of the U-shape of the connecting beam assembly 1, which is beneficial to improving the stability of the middle support of the connecting beam assembly 1.

[0047] Furthermore, the connecting beam assembly 1 and the support frame 2 are spaced apart vertically, so that the support frame 2 is placed entirely within the orthographic projection of the U-shaped structure of the connecting beam assembly 1, which facilitates the reinforcement of the U-shaped bottom of the U-shaped structure through the internal support frame 2.

[0048] Compared with the prior art, the fender connecting bracket provided in this application sets the connecting beam group 1 as a U-shaped structure, and fixes both ends of the opening side of the U-shaped structure to the cabin longitudinal beam 6, so as to form two sets of connection points at both ends of the opening side of the U-shaped structure, thereby increasing the number of connection points between the inner side of the connecting beam group 1 and the cabin longitudinal beam 6, which is beneficial to enhancing the connection strength between the connecting beam group 1 and the cabin longitudinal beam 6.

[0049] Furthermore, this application includes a support frame 2, which is connected to the cabin longitudinal beam 6 via an inner extension 22 and an outer extension 23 connected to the U-shaped bottom of the U-shaped structure, thereby achieving the connection between the support frame 2 and the connecting beam group 1. Therefore, the support frame 2 of this application can form a connecting bridge between the U-shaped bottom of the U-shaped structure and the cabin longitudinal beam 6, further improving the connection and support strength between the connecting beam group 1 and the cabin longitudinal beam 6.

[0050] Compared to the cantilever beam structure in traditional technology, the connecting beam group 1 in this application forms two sets of connection points on the inner side through the two ends of the U-shape, and a set of connection reinforcement points on the outer side through the bottom of the U-shape. The inner connection points are directly fixed to the longitudinal beam 6 of the engine compartment, and the outer reinforcement points are indirectly fixed to the longitudinal beam 6 of the engine compartment through the support frame 2. This simultaneously enhances the connection and support strength of the connecting beam group 1 in both the inner and outer directions, thereby improving the anti-bump load capacity of the support structure, which is conducive to improving the stability of the fender connection and support, avoiding deformation and cracking problems, and optimizing the overall vehicle performance.

[0051] Please see Figure 2 In some possible embodiments, the fender connecting bracket also includes a reinforcing plate 3; the reinforcing plate 3 is disposed inside the support frame 2; the upper end of the reinforcing plate 3 is connected to the nacelle longitudinal beam 6, and the lower end abuts against the inner extension 22; wherein, one end of the inner extension 22 extends downward through the nacelle longitudinal beam 6; the reinforcing plate 3 extends downward with the support frame 2, and multiple connecting bolts are provided vertically and vertically between the reinforcing plate 3 and the inner extension 22.

[0052] By setting the reinforcing plate 3, the connection strength between the inner side of the support frame 2 and the cabin longitudinal beam 6 can be improved. Specifically, one end of the support frame 2 extends downward, and the reinforcing plate 3 extends downward with the support frame 2, which can facilitate the setting of multiple connecting bolts. The multiple bolts are set at intervals, which can increase the number of connection points between the reinforcing plate 3 and the inner extension 22, thereby enhancing the connection strength between the support frame 2 and the cabin longitudinal beam 6.

[0053] Furthermore, in addition to the connection between the inner extension 22 and the cabin longitudinal beam 6, this application also provides a reinforcing plate 3. Moreover, by extending the inner extension 22 downward, the inner extension 22 can be indirectly connected to the cabin longitudinal beam 6 through the connection between the extension end of the inner extension 22 and the reinforcing plate 3, and the connection between the reinforcing plate 3 and the cabin longitudinal beam 6, thereby enhancing the overall connection strength between the support frame 2 and the cabin longitudinal beam 6.

[0054] Specifically, the number of connecting bolts can be selectively set according to actual needs; preferably, there are two sets of connecting bolts, which are arranged vertically and horizontally; and when the reinforcing plate 3 extends forward or backward with the inner extension 22, the two sets of connecting bolts are also arranged vertically and horizontally.

[0055] Please see Figure 2 and Figure 3 In some embodiments, the upper end of the inner extension 22 is fixed to the outer side of the nacelle longitudinal beam 6; the upper end of the reinforcing plate 3 is bent inward and abuts against the bottom of the nacelle longitudinal beam 6, and is fixedly connected to the nacelle longitudinal beam 6.

[0056] By bending the upper end of the reinforcing plate 3 to fix it to the bottom of the cabin longitudinal beam 6, the inner extension 22 can be connected to the bottom of the cabin longitudinal beam 6 through the reinforcing plate 3. Since the upper end of the inner extension 22 is also connected to the outer side of the cabin longitudinal beam 6, the inner extension 22 in this application can form connection points on the outer side and bottom of the cabin longitudinal beam 6, which is beneficial to further enhance the connection strength between the support frame 2 and the cabin longitudinal beam 6.

[0057] Specifically, a direct connection between the support frame 2 and the longitudinal beam 6 is formed on the outside of the cabin longitudinal beam 6, and an indirect connection between the support frame 2 and the longitudinal beam 6 is formed at the bottom of the cabin longitudinal beam 6, so as to improve the connection strength between the support frame 2 and the cabin longitudinal beam 6.

[0058] For example, the reinforcing plate 3 is an L-shaped plate, one side of which is fixed to the inner extension 22 by connecting bolts, and the other side is connected to the cabin longitudinal beam 6 by fixing bolts.

[0059] It should be understood that when the support frame 2 extends forward or backward, the reinforcing plate 3 extends in the direction of the inner extension 22, and at this time the extension directions of the two sides of the L-shaped plate are inclined to each other.

[0060] By further optimizing the connection structure between the reinforcing plate 3 and the engine compartment longitudinal beam 6, the connection between the support frame 2 and the engine compartment longitudinal beam 6 becomes tighter and more stable, further improving the strength of the connection between the fender connecting bracket and the vehicle body. This helps to reduce the deformation of the fender caused by stress during vehicle operation and improves the overall connection rigidity of the fender.

[0061] Please see Figure 1 In some possible embodiments, the portion of the support frame 2 connected between the outer extension 23 and the inner extension 22 is defined as the main body 21; the main body 21 is provided with a plurality of triangular cavities 211 that extend from front to back, and the plurality of triangular cavities 211 are arranged at intervals around the center of the main body 21 to divide the main body 21 into a plurality of triangular support structures.

[0062] The triangular support structure has good support stability. In this application, by setting a triangular cavity 211, multiple triangular support structures are formed, which is beneficial to improving the support strength of the main body 21. Furthermore, the multiple triangular support structures are set around the center of the main body 21, which is beneficial to forming an X-shaped support structure with the center of the main body 21 as the support point, thereby improving the support strength of the main body 21.

[0063] For example, the main body 21 is a plate-shaped main body plate with a plurality of triangular cavities 211. The triangular cavities 211 can be used as weight-reducing holes to reduce the weight of the main body 21.

[0064] Specifically, the number of triangular cavities 211 can be selectively set according to actual needs; optionally, a triangular cavity 211 is provided on the upper and lower sides of the center of the main body 21, and two triangular cavities 211 are provided on the inner and outer sides of the center of the main body 21 to form an X-shaped support structure.

[0065] Furthermore, a first flange structure is provided on the front or rear side of each triangular cavity 211. The first flange structure is used to enhance the support strength at the triangular cavity 211.

[0066] Optionally, a second flange structure is also provided at the ends of the inner extension 22 and the outer extension 23. The second flange structure is used to enhance the support strength of the inner extension 22 and the outer extension 23.

[0067] Please see Figure 1 In some embodiments, the support frame 2 is provided with multiple reinforcing ribs 24, which are interlaced to form multiple support grids.

[0068] By setting multiple reinforcing ribs 24, the support strength of the support frame 2 itself can be further improved; by forming multiple support grids by interlacing multiple reinforcing ribs 24, a grid support structure can be formed on the support frame 2 to ensure the overall support stability of the support frame 2.

[0069] For example, the staggered arrangement of the multiple reinforcing ribs 24 can be selectively set according to actual needs, and the support grid formed by the staggered arrangement can be irregular shapes such as triangles, rectangles, trapezoids and pentagons.

[0070] Optionally, multiple reinforcing ribs 24 are interlaced to form multiple X-shaped structures, so that the shape of each support grid is triangular, thereby further enhancing the support strength of the main body 21 through multiple triangular support grids.

[0071] Optionally, multiple reinforcing ribs 24 intersect to form multiple square-shaped structures, so that each support grid is rectangular, thereby further enhancing the support strength of the main body 21 through multiple rectangular support grids.

[0072] Specifically, the reinforcing rib 24 can be selectively arranged on the front or rear side of the support frame 2; preferably, the reinforcing rib 24 is arranged on the same side as the first flange structure and the second flange structure.

[0073] Specifically, the main body 21 is provided with a first reinforcing rib 24 and forms a first support grid accordingly; the inner extension 22 is provided with a second reinforcing rib 24 and forms a second support grid accordingly; the outer extension 23 is provided with a third reinforcing rib 24 and forms a third support grid accordingly.

[0074] Therefore, the staggered arrangement of the reinforcing ribs 24 further increases the strength and stability of the support frame 2, improves the overall rigidity of the fender connecting bracket, and enables the fender to better resist external forces during vehicle operation, reducing the risk of deformation and cracking, thereby improving product quality.

[0075] For example, the main body 21, the inner extension 22 and the outer extension 23 are provided as an integral structure.

[0076] Please see Figure 1 or Figure 2 In some possible embodiments, the fender connecting bracket further includes a first connecting plate 4 and a second connecting plate 5; one end of the first connecting plate 4 is connected to the support frame 2, and the other end extends upward and is fixed to the connecting beam assembly 1; the second connecting plate 5 is spaced apart from the first connecting plate 4; one end of the second connecting plate 5 is fixedly connected to the connecting beam assembly 1, and the other end is used to fix it to the fender.

[0077] The first connecting plate 4 is set to connect the support frame 2 and the connecting beam group 1; the second connecting plate 5 is set to connect the connecting beam group 1 and the fender. The first connecting plate 4 and the second connecting plate 5 can be used to make up for the height gap between the connecting beam group 1 and the support frame 2 and the fender, thereby facilitating the intermediate connection and support function of the connecting beam group 1.

[0078] Specifically, the lower end of the first connecting plate 4 is fixed to the upper end of the outer extension 23, and the upper end is fixed to the U-shaped bottom of the connecting beam assembly 1; optionally, the first connecting plate 4 can be fixed by fixing bolts, fixing rivets or welding.

[0079] Optionally, the first connecting plate 4 can be adapted to have a bending radius to meet the installation requirements of the outer extension 23 and the connecting beam assembly 1. For example, to accommodate the bending radius of the first connecting plate 4, the upper end of the outer extension 23 has an outwardly bent reinforcing edge structure, which is fixedly connected to the bent lower end of the first connecting plate 4 by connecting bolts.

[0080] Specifically, the lower end of the second connecting plate 5 is fixed to the U-shaped bottom of the connecting beam assembly 1. The fixing method can be rivet fixing, bolt fixing or welding fixing. For example, the second connecting plate 5 is welded to the U-shaped bottom of the connecting beam assembly 1; and the upper end of the second connecting plate 5 is fixed to the fender. The fixing method can be bolt fixing or rivet fixing.

[0081] It should be understood that the connections achieved by fixing bolts and connecting bolts in this application all require the addition of connecting nuts for fixation, and the matching method of connecting nuts and bolts is prior art, which will not be described in detail here.

[0082] Please see Figure 1 In some embodiments, there are two second connecting plates 5, which are symmetrically distributed on the front and rear sides of the first connecting plate 4.

[0083] By symmetrically distributing the second connecting plates 5 in front and behind the first connecting plate 4, the symmetry of the fender connection in the front and rear directions can be achieved, which is beneficial to improving the uniformity of the stress on the connecting beam group 1, enhancing the connection between the fender connecting bracket and the fender, helping to improve the overall connection stiffness of the fender, and improving the support stability of the connecting beam group 1.

[0084] It should be understood that the number of the second connecting plates 5 can be reasonably set according to the installation length of the fender. Preferably, the number of the second connecting plates 5 is an even number, and the number of the second connecting plates 5 distributed on the front and rear sides of the first connecting plate 4 is the same.

[0085] The addition of multiple second connecting plates 5 increases the number of connection points between the fender connecting bracket and the fender, which helps to improve the connectivity between the fender connecting bracket and the fender, thereby improving the overall connection rigidity of the fender and making the fender installation more stable.

[0086] Optionally, the second connecting plate 5 has a certain extension length in the vertical direction to increase the overlapping and contact area between the second connecting plate 5 and the fender. In this case, multiple sets of fixing bolts can be set at intervals above and below to improve the connection stability between the second connecting plate 5 and the fender.

[0087] Please see Figure 1 In some possible embodiments, the connecting beam assembly 1 includes a rear end beam 11, a front end beam 12, and a middle beam 13; one end of the rear end beam 11 is fixed to the nacelle longitudinal beam 6, and the other end extends toward the fender; the front end beam 12 is spaced apart on the front side of the rear end beam 11 and is fixedly connected to the nacelle longitudinal beam 6; the two ends of the middle beam 13 are correspondingly connected to the front end beam 12 and the rear end beam 11 to form a U-shaped structure; the middle beam 13 is connected to the fender and the support frame 2 respectively.

[0088] It should be understood that the front beam 12, the middle beam 13 and the rear beam 11 are connected in sequence to form a U-shaped structure. When the two ends of the opening side of the U-shaped structure are fixed to the longitudinal beam 6 of the cabin, a square-shaped support structure can be formed.

[0089] Specifically, both the front beam 12 and the rear beam 11 are welded and fixed to the longitudinal beam 6 of the engine room; the connection between the front beam 12, the rear beam 11 and the intermediate beam 13 is also fixed by welding. Optionally, the connection between the front beam 12, the rear beam 11 and the intermediate beam 13 can also be fixed by an intermediate connecting plate and fixing bolts.

[0090] By setting front beam 12 and rear beam 11 with front and rear intervals, two sets of connection points are used to connect the inner side of the beam group 1. By setting middle beam 13, the connection reinforcement point on the outer side of the beam group 1 is used to connect and fix the front beam 12 and rear beam 11.

[0091] Optionally, an auxiliary beam can be provided between the intermediate beam 13 and the engine compartment longitudinal beam 6. The auxiliary beam extends along the inside and outside of the vehicle body and is spaced apart along the front and rear of the vehicle body to further enhance the support strength of the auxiliary beam, thereby ensuring the connection stability of the fender connecting bracket.

[0092] Please see Figure 1 In some embodiments, one end of the intermediate beam 13 is connected to the front beam 12, and the other end is bent downwards and extends; the extended end of the rear beam 11 is also bent downwards and connected to the bent end of the intermediate beam 13.

[0093] By bending the other end of the intermediate beam 13 downwards and bending the extension end of the rear beam 11 downwards, it is beneficial to create clearance space at the extension end of the rear beam 11, avoid interference between the connection between the rear beam 11 and the intermediate beam 13 and other internal structural components, and ensure the independence and stability of the connecting beam group 1 support.

[0094] Specifically, the intermediate beam 13 includes a first connecting part and a second connecting part. The first connecting part is arranged parallel to the longitudinal beam 6 of the cabin and is connected to the front beam 12. The first connecting part is connected to the fender and the support frame 2 respectively. One end of the second connecting part is connected to the first connecting part, and the other end is bent downward and extended to connect to the rear beam 11.

[0095] Optionally, the intermediate beam 13 has an L-shaped structure, with one side of the L-shaped structure connected to the fender and the support frame 2 respectively, and the other side extending downward; the extended end of the rear beam 11 bends downward and is connected to the extended side of the L-shaped structure.

[0096] Furthermore, by bending the extension end of the rear beam 11 downwards and making the middle beam 13 into an L-shaped structure, the extension end of the rear beam 11 can be lowered so that the lowered part at the rear can be connected to other internal auxiliary parts or body structure. This further optimizes the connection method of the connecting beam group 1, enhances the overall stability and rigidity of the connecting beam group 1, thereby improving the overall performance of the fender connecting bracket, helping to improve the overall connection rigidity of the fender, and reducing the possibility of problems occurring in the fender during use.

[0097] Specifically, when the sunken portion is connected to other internal auxiliary components, the connecting beam assembly 1 can provide connection points for other internal auxiliary components to enhance the connection strength of other internal auxiliary components; when the sunken portion is connected to other body parts, it can improve the installation stability of the connecting beam assembly 1 and improve the fender mounting bracket's ability to resist bump loads.

[0098] Based on the same inventive concept, this application also provides a vehicle that includes the aforementioned fender connecting bracket.

[0099] The vehicle provided in this application, having included the aforementioned fender connecting bracket, possesses all the beneficial effects of the aforementioned fender connecting bracket. It has high support and connection strength, which can improve the bracket structure's resistance to bump loads, improve the stability of the fender connection and support, thereby avoiding deformation and cracking problems and optimizing the overall performance of the vehicle.

[0100] Specifically, the fender connection structure of the vehicle provided in this application has been optimized, which improves the overall connection rigidity of the fender, reduces cracking problems in later testing and the market, thereby improving the overall quality of the vehicle, ensuring the stability of the vehicle's appearance and overall performance, and helping to enhance the vehicle's market competitiveness.

[0101] 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.
