[0045] The rear bumper mounting bracket 10 and the vehicle according to the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0046] Referring to Figures 1-6 As shown in the drawings, the rear bumper mounting bracket 10 comprises a vehicle body connecting plate 1, a rear bumper mounting plate 2 and a base plate 3, the vehicle body connecting plate 1 has a connecting surface 11 adapted to be fixedly attached to the vehicle body 20, the rear bumper mounting plate 2 is located below the vehicle body connecting plate 1, the rear bumper mounting plate 2 has a rear bumper mounting hole 21 adapted to be connected to the rear bumper 30, and the base plate 3 is connected between the vehicle body connecting plate 1 and the rear bumper mounting plate 2.

[0047] Specifically, the upper end of the base plate 3 is connected to the vehicle body connecting plate 1, the lower end of the base plate 3 is connected to the rear bumper mounting plate 2, the base plate 3 can increase the spacing distance of the vehicle body connecting plate 1 and the rear bumper mounting plate 2 in the vehicle height direction (up-down direction, i.e. Z direction of the vehicle coordinate system), the connecting surface 11 of the vehicle body connecting plate 1 and the vehicle body 20 can be fixedly attached by welding, bonding, fastener connection and the like, the rear bumper mounting hole 21 of the rear bumper mounting plate 2 can be connected to the rear bumper 30 by a fastener such as a buckle or a bolt, so that the rear bumper 30 is fixed to the vehicle body 20 through the rear bumper mounting bracket 10.

[0048] Referring to Figure 2As shown, the normal line d1 of the connecting surface 11 is in the vehicle length direction (front-rear direction, i.e., X direction of the vehicle coordinate system), and the projection of the normal line d1 of the connecting surface 11 on the vehicle width direction (left-right direction, i.e., Y direction of the vehicle coordinate system) is parallel to the axis d2 of the rear bumper mounting hole 21 or the included angle a is less than 30°, for example, the included angle a is 5° or 20° or 30°. It can be understood that the direction of the normal line d1 of the connecting surface 11 is perpendicular to the connecting surface 11, and the direction of the normal line d1 of the connecting surface 11 is also the direction in which the connecting surface 11 is connected to the vehicle body 20. When the projection of the normal line d1 of the connecting surface 11 on the vehicle width direction is parallel to the axis d2 of the rear bumper mounting hole 21, the direction in which the rear bumper 30 is connected to the rear bumper mounting hole 21 by the fastener is also the front-rear direction of the vehicle. When the projection of the normal line d1 of the connecting surface 11 on the vehicle width direction has an included angle a less than 30° with the axis d2 of the rear bumper mounting hole 21, the direction in which the rear bumper 30 is connected to the rear bumper mounting hole 21 by the fastener is approximately the front-rear direction of the vehicle. That is, when the projection of the normal line d1 of the connecting surface 11 on the vehicle width direction is parallel to the axis d2 of the rear bumper mounting hole 21, the rear bumper mounting bracket 10 as a whole can be in a flat plate shape. When the projection of the normal line d1 of the connecting surface 11 on the vehicle width direction has an included angle a less than 30° with the axis d2 of the rear bumper mounting hole 21, the rear bumper mounting bracket 10 as a whole can be in an approximately flat plate structure. When the points at which the vehicle body 20 and the rear bumper 30 need to be fixed are staggered in the up-down direction, the downward dimension of the vehicle body 20 can be extended by the rear bumper mounting bracket 10 to provide the rear bumper mounting hole 21 for fixing the rear bumper 30. The rear bumper mounting hole 21 can effectively fix the rear bumper 30, so that the rigidity and modal of the rear bumper 30 after installation can meet the target requirements.

[0049] According to the rear bumper mounting bracket 10 of the embodiment of the present application, the projection of the normal line d1 of the connecting surface 11 on the vehicle width direction is parallel to the axis d2 of the rear bumper mounting hole 21 or the included angle a is less than 30°. When the points at which the vehicle body 20 and the rear bumper 30 need to be fixed are staggered in the up-down direction, the rear bumper mounting bracket 10 can provide the rear bumper mounting hole 21 below the vehicle body 20. The rear bumper mounting hole 21 can effectively fix the rear bumper 30, so that the rigidity and modal of the rear bumper 30 after installation can meet the target requirements, thereby facilitating the stability and reliability of the connection between the rear bumper 30 and the vehicle body 20.

[0050] In some embodiments of the present application, as shown in Figure 1 , Figure 3 and Figure 4 , the rear bumper mounting bracket 10 further comprises a guide flange 4 connected to the edge of the rear bumper mounting plate 2 facing the rear bumper 30 and extending in the axial direction of the rear bumper mounting hole 21. The guide flange 4 can provide a guide function when the rear bumper 30 is assembled, and the guide flange 4 can also improve the local rigidity of the rear bumper mounting plate 2.

[0051] Specifically, when the rear bumper 30 is assembled, the direction (a direction in the drawing) in which the rear bumper 30 is assembled is the width direction of the vehicle, that is, the direction in which the rear bumper 30 is assembled is perpendicular or approximately perpendicular to the axial direction of the rear bumper mounting hole 21, and when the rear bumper 30 is assembled, the guide flange 4 can provide a guide function for the rear bumper 30, and the rear bumper 30 can slide along the guide flange 4 after the rear bumper 30 contacts the guide flange 4 to the rear bumper mounting plate 2, so as to facilitate the assembly of the rear bumper 30. Figure 4

[0052] Referring to Figure 4 , the size of the guide flange 4 in the axial direction of the rear bumper mounting hole 21 is L1, and the value of L1 can be 2mm-5mm, for example, L1 is 2mm or 3mm or 5mm, and the guide flange 4 and the rear bumper mounting plate 2 have a round corner R3 therebetween to improve the guide effect of the guide flange 4 and control the springback of the guide flange 4 during stamping manufacturing.

[0053] In some embodiments of the present application, referring to Figure 4 , the rear bumper mounting plate 2 has a mounting surface 22 adapted to be attached to the rear bumper 30, the rear bumper mounting hole 21 is provided in the mounting surface 22, and the guide flange 4 extends away from the mounting surface 22, so that the guide flange 4 can prevent the rear bumper 30 from being misassembled.

[0054] Specifically, in order to ensure the consistency of assembly, the rear bumper 30 needs to be attached to the mounting surface 22 of the rear bumper mounting plate 2, that is, the rear bumper 30 is attached to the mounting surface 22 of the rear bumper mounting plate 2 for correct assembly, and the rear bumper 30 is attached to the side away from the mounting surface 22 of the rear bumper mounting plate 2 for incorrect assembly, and when the guide flange 4 extends away from the mounting surface 22, the guide flange 4 can block the rear bumper 30 from being attached to the side away from the mounting surface 22 of the rear bumper mounting plate 2, so that the guide flange 4 has a foolproof function to prevent the rear bumper 30 from being misassembled.

[0055] In some embodiments of the present application, referring to Figure 4 , the minimum spacing distance between the guide flange 4 and the inner wall of the rear bumper 30 is D1, and the relationship D1≥5mm is satisfied, that is, the minimum spacing distance between the guide flange 4 and the inner wall of the rear bumper 30 is greater than or equal to 5mm, for example, D1 is 5mm or 6mm or 7mm, so that the guide flange 4 and the inner wall of the rear bumper 30 have sufficient safety distance, and when the rear bumper mounting bracket 10 and the rear bumper 30 are subjected to external load, the guide flange 4 and the rear bumper 30 are prevented from colliding and interfering due to deformation, and the risk of abnormal vibration and noise is reduced.

[0056] In some embodiments of the present application, referring to Figure 1 ​As shown, the rear bumper mounting bracket 10 further comprises a reinforcing flange 5, the edges of the vehicle body connecting plate 1, the edges of the base plate 3 and the edges of the rear bumper mounting plate 2 which are not connected with the guide flange 4 are connected with the reinforcing flange 5, so as to improve the strength and rigidity of the rear bumper mounting bracket 10 as a whole.

[0057] Specifically, the reinforcing flange 5 is connected with the edges of the vehicle body connecting plate 1, the base plate 3 and the rear bumper mounting plate 2, and the reinforcing flange 5, the vehicle body connecting plate 1, the base plate 3 and the rear bumper mounting plate 2 can jointly form a groove structure, so as to improve the strength and rigidity of the rear bumper mounting bracket 10 as a whole, enhance the bending and torsion resistance of the rear bumper mounting bracket 10, and reduce the deformation and fracture risk of the rear bumper mounting bracket 10 when bearing load.

[0058] In the embodiment, the rear bumper mounting bracket 10 can be integrally stamped from a steel plate blank, and the edges of the rear bumper mounting plate 2 which are not connected with the guide flange 4 are connected with the reinforcing flange 5, so as to facilitate the stamping of the rear bumper mounting bracket 10.

[0059] It can be understood that for the vehicle body connecting plate 1, the rear bumper mounting plate 2 and the base plate 3, the guide flange 4 and the reinforcing flange 5 are arranged on the outer side of the vehicle body connecting plate 1, the rear bumper mounting plate 2 and the base plate 3, and since the rear bumper mounting bracket 10 is integrally stamped from a steel plate blank, in order to avoid the position overlap of the guide flange 4 and the reinforcing flange 5 which leads to poor processability of the rear bumper mounting bracket 10, the reinforcing flange 5 is connected with the edges of the vehicle body connecting plate 1 and the edges of the base plate 3, and the reinforcing flange 5 is only connected with the edges of the rear bumper mounting plate 2 which are not connected with the guide flange 4, that is, the same edges of the rear bumper mounting plate 2 are connected with one of the reinforcing flange 5 and the guide flange 4, so as to avoid the same edges of the rear bumper mounting plate 2 being connected with two flanges at the same time, thereby facilitating the manufacturing difficulty of the rear bumper mounting bracket 10.

[0060] In some embodiments of the present application, referring to Figure 5 As shown, the reinforcing flange 5 extends away from the connecting surface 11, so as to avoid the reinforcing flange 5 affecting the fit of the connecting surface 11 and the vehicle body 20.

[0061] It can be understood that when the reinforcing flange 5 extends away from the connecting surface 11, the reinforcing flange 5 can be avoided from protruding towards the vehicle body 20 relative to the connecting surface 11, and when the connecting surface 11 is fixedly fitted with the vehicle body 20, the reinforcing flange 5 is avoided from interfering with the vehicle body 20.

[0062] Specifically, to avoid the interference between the length of the reinforcing flange 5 and the periphery, and to enable the reinforcing flange 5 to be formed by stamping, and to have sufficient rigidity to meet the installation of the rear bumper 30, the dimension of the reinforcing flange 5 in the normal direction of the connecting surface 11 is L2, L2 = 3 mm, and the reinforcing flange 5 has a round corner R3 between the vehicle body connecting plate 1, the base plate 3 and the rear bumper mounting plate 2, to avoid stress concentration and reduce the rebound of the reinforcing flange 5, facilitating the stamping of the reinforcing flange 5.

[0063] In some embodiments of the present application, as shown in FIG. 1, the reinforcing flange 5 and the connecting surface 11 are located on the same side of the vehicle body connecting plate 1 facing the vehicle body 20, that is, the reinforcing flange 5 extends towards the vehicle body 20, and the vehicle body 20 can be provided with a corresponding avoidance groove corresponding to the reinforcing flange 5, and when the connecting surface 11 is fixed to the vehicle body 20, the reinforcing flange 5 can be inserted into the avoidance groove, and the avoidance groove can be positioned and matched with the reinforcing flange 5, and the reinforcing flange 5 can be clamped between the two side walls of the avoidance groove, so that the connecting surface 11 is assembled to the predetermined position on the vehicle body 20, thereby facilitating the position accuracy of the connecting surface 11 and the vehicle body 20, and facilitating the assembly of the rear bumper mounting bracket 10 and the vehicle body 20.

[0064] In some embodiments of the present application, as shown in FIG. 1, Figure 6 The minimum distance between the reinforcing flange 5 and the rear bumper 30 is D2, which satisfies the relationship: 3 mm ≤ D2 ≤ 5 mm, that is, the minimum distance between the reinforcing flange 5 and the rear bumper 30 is 3 mm to 5 mm, for example, D2 is 3 mm or 4 mm or 5 mm, to ensure the lightweight of the rear bumper mounting bracket 10 and to have sufficient safety distance between the reinforcing flange 5 and the rear bumper 30.

[0065] It can be understood that when D2 < 3 mm, the reinforcing flange 5 is prone to collide and interfere with the rear bumper 30 when the rear bumper mounting bracket 10 and the rear bumper 30 are subjected to external load, resulting in abnormal vibration and noise. When D2 > 5 mm, the overall size of the rear bumper mounting bracket 10 is large, which is not conducive to the lightweight of the rear bumper mounting bracket 10.

[0066] In some embodiments of the present application, as shown in FIG. 1, Figure 1 The vehicle body connecting plate 1, the base plate 3 and the rear bumper mounting plate 2 jointly form a reinforcing boss 6, which can improve the strength and rigidity of the rear bumper mounting bracket 10 as a whole, enhance the bending and torsional resistance of the rear bumper mounting bracket 10, and reduce the risk of deformation and fracture of the rear bumper mounting bracket 10 under load.

[0067] It should be noted that the connection between the substrate 3 and the vehicle body connecting plate 1 and the connection between the substrate 3 and the rear bumper mounting plate 2 can have a fillet structure for transition, and the reinforcing boss 6 can extend outwardly from the substrate 3 at least to the fillet structure of the upper and lower connection, so that the reinforcing boss 6 can not only improve the strength and rigidity of the rear bumper mounting bracket 10 as a whole, but also reduce the rebound of the fillet structure of the connection during stamping, thereby facilitating the improvement of the shape accuracy of the rear bumper mounting bracket 10 and the control of the large surface rebound of the rear bumper mounting bracket 10 during stamping.

[0068] In some embodiments of the present application, referring to Figure 7 The protruding direction of the reinforcing boss 6 is the same as the extending direction of the reinforcing flange 5, and the reinforcing flange 5 and the reinforcing boss 6 can make the cross section of the rear bumper mounting bracket 10 present a "bow" structure, thereby improving the strength and rigidity of the rear bumper mounting bracket 10.

[0069] Referring to Figures 1-7 The vehicle according to another aspect of the present application comprises a vehicle body 20, a rear bumper 30 and the rear bumper mounting bracket 10 of the above-mentioned embodiments.

[0070] According to the vehicle of the embodiments of the present application, when the points where the vehicle body 20 and the rear bumper 30 need to be fixed are staggered in the up-down direction, the rear bumper mounting hole 21 can be provided below the vehicle body 20 by the rear bumper mounting bracket 10, which can effectively fix the rear bumper 30, so that the rigidity and modal of the rear bumper 30 after installation can meet the target requirements, thereby facilitating the improvement of the stability and reliability of the connection between the rear bumper 30 and the vehicle body 20.

[0071] In some embodiments of the present application, referring to Figures 1-5 The vehicle body 20 comprises a rear wheel cover outer plate 201 and a rear wall outer plate rear extension plate 202, the connecting surface 11 is attached to the rear wheel cover outer plate 201, and the vehicle body connecting plate 1, the rear wheel cover outer plate 201 and the rear wall outer plate rear extension plate 202 are welded and connected, so as to facilitate the connection of the vehicle body connecting plate 1, the rear wheel cover outer plate 201 and the rear wall outer plate rear extension plate 202, and ensure the connection strength of the rear bumper mounting bracket 10 and the vehicle body 20.

[0072] Specifically, the vehicle body connecting plate 1, the rear wheel cover outer plate 201 and the rear wall outer plate rear extension plate 202 can be connected by spot welding, the rear wheel cover outer plate 201 is located between the vehicle body connecting plate 1 and the rear wall outer plate rear extension plate 202, and the rear wheel cover outer plate 201 and the rear wall outer plate rear extension plate 202 can provide sufficient support strength to the vehicle body connecting plate 1.

[0073] The number of welding points of the vehicle body connecting plate 1, the rear wheel cover outer plate 201 and the rear wall outer plate rear extension plate 202 can be two to ensure the connection strength and avoid the cost increase and the size increase of the parts caused by too many welding points. The base plate 3 can be provided with a positioning hole 31 during welding. In the vehicle width direction, the distance between the two welding points of the vehicle body connecting plate 1 is L3, L3=30mm. The distance between each welding point and the edge of the vehicle body connecting plate 1 is L4, L4=7.5mm. That is, the size of the vehicle body connecting plate 1 in the vehicle width direction is 30mm+2*7.5mm=45mm, so as to control the size of the rear bumper mounting bracket 10 and reduce the weight and cost of the rear bumper mounting bracket 10.

[0074] In some embodiments of the present application, referring to Figure 6 As shown in the figure, the minimum distance between the reinforcing flange 5 connected with the vehicle body connecting plate 1 and the R angle of the rear wheel cover outer plate 201 is D3, D3≥3mm. When the rear bumper mounting bracket 10 and the rear wheel cover outer plate 201 are subjected to external load, the rear bumper mounting bracket 10 and the rear wheel cover outer plate 201 are prevented from colliding and interfering due to deformation, and the risk of abnormal vibration and abnormal noise is reduced.

[0075] According to the vehicle of the embodiment of the present application, the rear bumper 30 can be fixed to the vehicle body 20 through three mounting points arranged in the up-down direction on the left and right sides of the front end of the vehicle. The mounting point in the middle position is fixed to the vehicle body 20 through the rear bumper mounting bracket 10. The connection of the rear bumper mounting bracket 10 and the mounting point in the middle position can improve the overall modal and stiffness of the rear bumper 30.

[0076] The rear bumper mounting bracket 10 is generally an "L" type bracket structure. The vehicle body connecting plate 1 and the base plate 3 extend along the height direction of the vehicle. The rear bumper mounting plate 2 extends along the width direction of the vehicle to the outside of the vehicle. When the mounting point in the middle position of the rear bumper 30 has a height difference with the corresponding vehicle body 20 in the up-down direction, the rear bumper mounting hole 21 of the rear bumper mounting bracket 10 can provide an effective mounting position for the rear bumper 30.

[0077] Meanwhile, by setting the reinforcing flange 5 and the reinforcing boss 6 structure, the cross section of the rear bumper mounting bracket 10 can be in the shape of a "bow" to improve the overall stiffness of the rear bumper mounting bracket 10 and provide a mounting position with sufficient stiffness for the rear bumper 30. In addition, the guide flange 4 can provide a guiding effect during the assembly of the rear bumper 30 to facilitate the installation of the rear bumper 30.

[0078] In some embodiments of the present application, the rear bumper mounting bracket 10 can be manufactured by a stamping process. The body connecting plate 1, the rear bumper mounting plate 2, the base plate 3, the guide flange 4 and the reinforcing flange 5 on the rear bumper mounting bracket 10 are integrally formed by stamping. The stamping-formed rear bumper mounting bracket 10 has high strength and stability, and can withstand various mechanical stresses and environmental conditions. At the same time, the rear bumper mounting bracket 10 manufactured by the stamping process has the advantages of high production efficiency, high precision and consistency, high material utilization rate, good design flexibility, low cost, etc.

[0079] Specifically, compared with manual processing or other forms of metal processing, the rear bumper mounting bracket 10 manufactured by the stamping process can be quickly and accurately produced in large quantities through stamping dies and automatic equipment. The stamping process greatly shortens the processing time of the rear bumper mounting bracket 10. This efficient production method is especially suitable for the automobile manufacturing field which requires large-scale manufacturing, and can significantly improve production efficiency and capacity.

[0080] During the manufacture of the rear bumper mounting bracket 10, precise control of the stamping die can ensure high precision and consistency of the rear bumper mounting bracket 10 in size and shape. Compared with manual processing, the stamping die eliminates the dimensional variation caused by human operation errors, thereby improving the quality stability and dimensional precision consistency of the product, ensuring the reliability of the product in use. The rear bumper 30 has good position after installation, avoiding large gaps and surface differences between the rear bumper 30 and the side outer panel of the vehicle, improving the quality of the vehicle.

[0081] In addition, through precise mold design and material layout, multiple rear bumper mounting brackets 10 can be arranged on a steel plate blank as much as possible to minimize material waste and reduce waste. At the same time, thinner steel plate blanks can be used to manufacture the rear bumper mounting bracket 10. The structural strength of the rear bumper mounting bracket 10 is ensured by setting the stamping-formed guide flange 4, reinforcing flange 5, reinforcing boss 6 and other structures on the rear bumper mounting bracket 10, reducing the amount of steel plate blank used and reducing production costs.

[0082] The design of the rear bumper mounting bracket 10 can be flexibly optimized and adjusted according to specific application requirements. Through different mold designs, the stamping process can easily realize various complex geometric shapes and structural requirements. For example, during the stamping manufacture of the rear bumper mounting bracket 10, the stamping die can perform processes such as drawing, trimming, punching, flanging and shaping on the steel plate blank to process the steel plate blank into the rear bumper mounting bracket 10.

[0083] In addition, although the initial investment cost of manufacturing the stamping die is high, for the automobile manufacturing industry, considering the unit cost of mass production, the rear bumper mounting bracket 10 manufactured by the stamping process is generally more economical than other manufacturing methods, and the high efficiency and high material utilization rate of the stamping process directly reduce the production cost, especially in large-scale production, which can significantly reduce the manufacturing cost of each product. This makes the rear bumper mounting bracket 10 have a clear price advantage in market competition, which can improve the market competitiveness and profitability of the enterprise.

[0084] It can be understood that the rear bumper mounting bracket 10 is an important part of the vehicle structure, which bears the function of connecting and fixing the vehicle body 20 and the rear bumper 30, and the rear bumper mounting bracket 10 can improve the stability, stiffness and modal response of the rear bumper after installation, thereby meeting various requirements of vehicle design.

[0085] Referring to Figures 1-7 In one embodiment of the present application, the rear bumper mounting bracket 10 is mainly composed of three parts: a vehicle body connecting plate 1, a rear bumper mounting plate 2 and a base plate 3, which effectively support and fix the rear bumper 30 through specific design and structural arrangement, so that the rear bumper 30 and the vehicle body 20 form a stable and reliable connection, specifically:

[0086] The vehicle body connecting plate 1 is located at the top of the entire rear bumper mounting bracket 10 structure, and the connecting surface 11 thereof can be used for spot welding with the vehicle body 20, and the normal direction d1 of the connecting surface 11 is parallel to the length direction of the vehicle, which ensures good connection with the vehicle body 20.

[0087] The rear bumper mounting plate 2 is located below the vehicle body connecting plate 1 and extends outward along the width direction of the vehicle, and the rear bumper mounting plate 2 has a mounting surface 22, which can ensure the accuracy and stability of the rear bumper 30 assembly when the mounting surface 22 is attached to the rear bumper 30. The rear bumper mounting hole 21 is provided on the mounting surface 22, and the rear bumper mounting hole 21 is connected with the rear bumper 30 through buckling or bolts, which ensures the firm fixation of the rear bumper 30. In addition, the included angle a between the normal direction of the connecting surface 11 and the projection of the axis d2 of the rear bumper mounting hole 21 in the width direction of the vehicle is less than 30°, which further ensures that the rear bumper mounting bracket 10 can stably fix the rear bumper 30 during installation.

[0088] The base plate 3 is connected between the vehicle body connecting plate 1 and the rear bumper mounting plate 2, and the base plate 3 can increase the vertical distance between the vehicle body connecting plate 1 and the rear bumper mounting plate 2, i.e. the interval distance in the height direction of the vehicle. This design helps to provide additional extension size when the fixing points of the vehicle body 20 and the rear bumper 30 are staggered in the up-down direction, so as to facilitate the installation of the rear bumper mounting hole 21 and ensure the stability and stiffness of the rear bumper 30.

[0089] In addition, the rear bumper mounting bracket 10 has some other structures to facilitate the use of the rear bumper mounting bracket 10, improve the reliability, stability and convenience of the rear bumper mounting bracket 10, and the rear bumper mounting bracket 10 has the following structures:

[0090] The guide flange 4 is located at the edge of the rear bumper mounting plate 2, extends in the axial direction of the rear bumper mounting hole 21, and extends away from the mounting surface 22. The design of the guide flange 4 not only improves the local stiffness of the rear bumper mounting plate 2, but also provides a guide function during the assembly of the rear bumper 30. The rear bumper 30 can slide along the guide flange 4 to the correct position during installation, thereby simplifying the assembly process and improving the assembly accuracy. In mass production of vehicles, the foolproof function of the guide flange 4 can prevent the rear bumper 30 from being installed incorrectly, thereby ensuring the consistency of vehicle assembly.

[0091] The reinforcing flange 5 is located at the edge of the vehicle body connecting plate 1, the base plate 3 and the rear bumper mounting plate 2, and the reinforcing boss 6 can extend outward from the base plate 3 to the fillet structure at the connection between the base plate 3 and the vehicle body connecting plate 1 and the rear bumper mounting plate 2. The arrangement of the reinforcing flange 5 and the reinforcing boss 6 not only enhances the strength and stiffness of the overall structure of the rear bumper mounting bracket 10, but also effectively reduces the risk of deformation and fracture of the rear bumper mounting bracket 10 under load. In addition, the protruding direction of the reinforcing boss 6 is the same as the extending direction of the reinforcing flange 5. Under the joint action of the reinforcing boss 6 and the reinforcing flange 5, the cross-sectional shape of the rear bumper mounting bracket 10 presents a more stable "arch" structure, thereby improving the reliability and durability of the rear bumper mounting bracket 10.

[0092] The structural design of the rear bumper mounting bracket 10 not only considers the assembly accuracy and structural strength, but also solves the problem of safe distance and collision interference between the rear bumper mounting bracket 10 and the rear bumper 30. For example, a sufficient minimum distance D1 is provided between the guide flange 4 and the inner wall of the rear bumper 30 to avoid collision interference between the rear bumper mounting bracket 10 and the rear bumper mounting bracket 10 under external load, thereby reducing the risk of abnormal vibration and noise.

[0093] At the same time, the rear bumper mounting bracket 10 can be integrally stamped from a piece of steel sheet, which not only ensures the integrity and strength of the structure of the rear bumper mounting bracket 10, but also facilitates the control of manufacturing cost and processing cycle. During the stamping process of the rear bumper mounting bracket 10, the design of the reinforcing flange 5 and the guide flange 4 not only considers the material springback and processing accuracy, but also effectively reduces the material deformation and springback that may occur during the manufacturing process through the application of the fillet structure.

[0094] The rear bumper mounting bracket 10 according to the embodiment of the present application is a novel vehicle bracket structure design, which not only considers the precision and safety of the rear bumper mounting bracket 10 assembly, but also focuses on the strength, rigidity and durability of the rear bumper mounting bracket 10 structure. The unique structure design and manufacturing process of the rear bumper mounting bracket 10 can effectively support and fix the rear bumper 30, and meet the strict requirements of modern vehicles in safety and stability. The rear bumper mounting bracket 10 has a wide application prospect in the field of automobile manufacturing and good product competitiveness.
