[0002] Currently, the rear bumper and side panel assembly form a diagonal seam extending upward and rearward on the side of the vehicle (in the front-to-back direction), and then form a horizontal seam with the rear combination lights directly behind the vehicle (in the left-to-right direction). The rear bumper bracket and rear combination lights (rear combination light bracket) are separately mounted on the side panel assembly. The rear bumper bracket follows the seam between the rear bumper and the vehicle's side panel, forming an inverted "7" shape. This results in a large drop in the rear bumper bracket, a complex structure, and difficult precision, which affects the clearance between the rear end of the rear bumper and the side panel assembly. Furthermore, to accommodate the rear bumper bracket, the various mounting surfaces on the side panel assembly must be adjusted, resulting in a large drop in the side panel shape and increasing the difficulty of stamping and welding the side panel. Utility Model Content

[0016] Furthermore, the rear end of the body side is provided with a first flange folded from the outside of the vehicle to the inside of the vehicle, a second flange folded below the first flange, and a mounting plate provided on the first flange; the second flange constitutes the connecting part, and the mounting plate constitutes the extending part.
[0017] Compared with the prior art, the present invention has the following advantages:
[0018] The rear bumper mounting structure described in the present invention is achieved by arranging a connecting portion and an extending portion on the vehicle body side, and the first mounting bracket is connected to the connecting portion along the left-right direction of the vehicle, the second mounting bracket is connected to the extending portion along the up-down direction of the vehicle, and the first connecting portion and the second connecting portion are both connected to the rear bumper. Compared with an integrally formed mounting bracket, it is beneficial to simplify the structure of the mounting bracket, to optimize the shape difference at the seam between the vehicle body side and the rear bumper, and to facilitate processing, manufacturing and installation. By connecting the first mounting bracket and the second mounting bracket to the vehicle body side, the installation accuracy of the rear bumper can be improved, thereby improving the gap surface difference between the rear bumper and the vehicle body side.
[0019] Secondly, the second mounting bracket is pre-installed on the extension portion via the snap-fitting portion. This allows the installer to initially determine the second mounting bracket's position during installation without the need for complex tools or lengthy adjustments, saving significant time for subsequent precise installation steps. The snap-fitting and snap-fitting holes in the snap-fitting portion are simple in structure, providing a strong snap-fitting effect. The sealing ring prevents moisture and dust from entering the vehicle body through this gap. The second mounting bracket is flat and block-shaped, with its thickness aligned with the vertical direction of the vehicle, enabling effective installation and connection within a limited space. This helps prevent deformation of the second mounting bracket during a collision, which could cause structural deformation of the vehicle's side panels.
[0020] Furthermore, the second mounting bracket is connected to the extension portion via a threaded pair, and the first mounting bracket is connected to the connecting portion via a threaded pair. This threaded pair connection provides a strong tightening force, ensuring a tight fit between the second mounting bracket and the extension portion, and a secure connection between the first mounting bracket and the connecting portion. Furthermore, the provision of a sealing ring effectively prevents water, dust, and other impurities from entering the connection portion, thereby ensuring the structural reliability of the connection. The first and second clamping blocks can be clamped together horizontally with the rear bumper, a connection method that is simple and quick to operate. Both the first and second clamping blocks are clamped together horizontally with the rear bumper, offering the advantage of simple installation and operation, thereby improving installation efficiency.
[0021] In addition, multiple first clamping blocks are spaced along the length of the first mounting bracket, and multiple second clamping blocks are spaced along the length of the second mounting bracket, creating a multi-point clamping connection between the rear bumper and the mounting bracket, thereby improving the reliability of the clamping connection. This multi-point connection method can more evenly distribute the external forces acting on the rear bumper, improving the stability of the connection. The first limiting arm and first support rib on the first bracket, as well as the second limiting arm and second support rib on the second mounting bracket, help prevent the rear bumper from shaking and shifting in the vertical direction, thereby improving the stability of the connection. The design of the first flange, second flange, and mounting plate at the rear end of the body side creates different connecting parts and extension parts through multiple folding, increasing the structural strength of the body side in this area.
[0022] In addition, another object of the present invention is to provide a vehicle, wherein the vehicle is provided with the rear bumper mounting structure as described above.
[0023] The vehicle described in the present invention is beneficial to improving the assembly efficiency and refinement of the vehicle by providing the above-mentioned rear bumper mounting structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0049] Example 1
[0050] This embodiment relates to a rear bumper mounting structure, which solves the problems of complex structure and installation of the integrated rear bumper mounting structure in the prior art and the large gap surface difference between the rear bumper 1 and the vehicle body side 2 by optimizing its own structure.
[0051] Overall, the rear bumper mounting structure comprises a first mounting bracket 3 and a second mounting bracket 4, located at the seam 100 between the rear bumper 1 and the bodyside panel 2. The rear end of the bodyside panel 2 has a connecting portion 201 extending downwardly along the vehicle's vertical axis, and an extension portion 202 extending from the exterior to the interior of the vehicle. The first mounting bracket 3 is connected to the connecting portion 201 along the vehicle's horizontal axis and has a first connecting portion. The second mounting bracket 4 is connected to the extension portion 202 along the vehicle's vertical axis and has a second connecting portion. Both the first and second connecting portions are used to connect to the rear bumper 1.
[0052] The rear bumper mounting structure described in this embodiment comprises a connecting portion 201 and an extending portion 202 provided on the bodyside 2. The first mounting bracket 3 is connected to the connecting portion 201 in the left-right direction of the vehicle, the second mounting bracket 4 is connected to the extending portion 202 in the up-down direction of the vehicle, and both the first and second connecting portions are connected to the rear bumper 1. Compared to an integrally formed mounting bracket, this facilitates a simplified mounting bracket structure, optimizes the design difference at the seam 100 between the bodyside 2 and the rear bumper 1, and facilitates manufacturing and installation. The connection between the first and second mounting brackets 3 and 4 and the bodyside 2 improves the installation accuracy of the rear bumper 1, thereby reducing the gap and flushness between the rear bumper 1 and the bodyside 2.
[0053] Based on the above overall introduction, an exemplary structure of the rear bumper mounting structure in this embodiment is as follows: Figures 1 to 4 As a preferred embodiment, as shown in Figure 7 As shown in FIG, the rear end of the body side panel 2 is provided with a first flange 203 folded from the outside of the vehicle to the inside of the vehicle, a second flange 204 folded below the first flange 203, and a mounting plate 205 provided on the first flange 203. The second flange 204 constitutes the connecting portion 201, and the mounting plate 205 constitutes the extending portion 202.
[0054] In this embodiment, the first flange 203, second flange 204, and mounting plate 205 at the rear end of the body side 2 are designed through multiple folds to form distinct connecting portions 201 and extension portions 202, thereby increasing the structural strength of the body side 2 in this area. Furthermore, the flange and mounting plate 205 structure conceals the first and second mounting brackets 3 and 4, enhancing the vehicle's appearance.
[0055] like Figure 7 As shown in FIG, the second flange 204 and the mounting plate 205 are arranged sequentially in the front-to-back direction of the vehicle. The mounting plate 205 extends from the first flange 203 toward the interior of the vehicle. The mounting plate 205 is folded downward toward the interior of the vehicle to form a lower flange 2052. The mounting plate 205 overlaps the first flange 203 and is welded to the first flange 203. The front end of the lower flange 2052 overlaps the rear end of the second flange 204 and is welded to the second flange 204, which helps to improve the installation security of the mounting plate 205.
[0056] Furthermore, the rear end of the mounting plate 205 is provided with an upwardly folded upper flange 2051. The provision of the upper flange 2051 and the lower flange 2052 further enhances the structural strength of the mounting plate 205. In practice, the mounting plate 205 is used to connect to the second mounting bracket 4. Its specifications are compatible with the second mounting bracket 4 and facilitate processing and molding. In this embodiment, a connecting plate 209 is further provided between the connecting portion 201 and the mounting plate 205. This connecting plate 209 is connected to the bottom of the connecting portion 201 and the lower flange 2052, thereby enhancing the structural strength and stability of the connecting portion 201 and the extension portion 202.
[0057] As a preferred embodiment, Figure 6 As shown in FIG, the first mounting bracket 3 is an elongated strip disposed along the split 100. It is connected to the connecting portion 201 via a threaded pair, with a sealing ring interposed between the two. To distinguish it from the sealing ring described below, this sealing ring is referred to as the first sealing ring. The threaded pair provides a strong fastening force, ensuring a tight connection between the first mounting bracket 3 and the connecting portion 201. The first sealing ring effectively prevents water, dust, and other impurities from entering the connection, thereby ensuring the structural reliability of the connection.
[0058] like Figures 3 to 5 As shown in , the thread pair includes a first bolt 301 that passes through the first mounting bracket 3 and the connecting portion 201 in sequence along the left-right direction of the vehicle, and a first nut 3011 that is arranged inside the connecting portion 201. Here, three first bolts 301 are arranged at intervals along the front-to-back direction of the vehicle. The first nut 3011 is arranged one-to-one with each first bolt 301, and the first sealing ring can be sleeved on the first bolt 301. In some embodiments, the first nut 3011 in this embodiment can be a plastic nut, such as Figure 10 As shown in , the threaded hole in the first nut 3011 is a blind hole, and the first nut 3011 is provided with a connecting flange for connecting to the connecting part 201. The plastic nut cooperates with the first bolt 301 through the threaded hole inside it to achieve a fastened connection.
[0059] During the tightening of the first bolt 301, the threads of the plastic nut engage with the threads of the first bolt 301, generating friction, thereby securing the first mounting bracket 3 and the connecting portion 201. Because plastic has a certain degree of elasticity, the plastic nut can, after tightening, cushion vibrations to a certain extent, reducing loosening of the connection.
[0060] To facilitate the installation of the first mounting bracket 3 on the connecting portion 201, as shown in FIG. Figure 7 and Figure 8As shown in FIG, two first positioning posts 306 are spaced apart on the side of the first mounting bracket 3 facing the connecting portion 201. First positioning holes 206 are provided on the connecting portion 201 to correspond to the first positioning posts 306. When the first mounting bracket 3 is installed in the left-right direction of the vehicle, the first positioning posts 306 are inserted into the corresponding first positioning holes 206 to ensure alignment between the first bolt 301 and the first nut 3011, thereby improving the installation accuracy and efficiency of the first mounting bracket 3. A fifth sealing ring 305 is sleeved on the first positioning posts 306 to enhance the sealing effect between the first positioning posts 306 and the first positioning holes 206.
[0061] As a preferred embodiment, a snap-fitting portion is provided between the second mounting bracket 4 and the extension portion 202. This snap-fitting portion is used to pre-install the second mounting bracket 4 on the extension portion 202. This arrangement allows the installer to initially determine the position of the second mounting bracket 4 during installation without the need for complex tools or lengthy adjustments, saving considerable time for subsequent precise installation steps. Furthermore, the snap-fitting portion helps prevent the second mounting bracket 4 from falling off the mounting plate 205, further enhancing the ease of installation.
[0062] In terms of specific structure, Figure 7 and Figure 11 As shown in . The snap-fitting portion includes a snap-fitting portion 401 provided on the second mounting bracket 4, and a snap-fitting hole 207 provided on the extension portion 202. The snap-fitting portion 401 and the snap-fitting hole 207 have simple structures, and the snap-fitting effect of the two is good. In addition, a sealing ring is provided on the outer cover of the snap-fitting portion 401, and the sealing ring is used to seal the gap between the extension portion 202 and the second mounting bracket 4. In order to facilitate the distinction from other sealing rings, the sealing ring provided on the snap-fitting portion 401 is referred to as a second sealing ring 4011. The provision of the second sealing ring 4011 helps prevent moisture and dust from entering the interior of the vehicle body through the gap. In specific implementation, the second sealing ring 4011 can be a sponge gasket. When the snap-fitting portion 401 and the snap-fitting hole 207 are in the snap-fitting state, the second sealing ring 4011 is clamped between the extension portion 202 and the second mounting bracket 4, and has a good sealing effect.
[0063] In some embodiments, the clip 401 is positioned in the middle of the top surface of the second mounting bracket 4 and includes two opposing clips. These clips, when positioned close together, can smoothly pass through the clip hole 207 and hook onto the mounting plate 205, thereby pre-installing the second mounting bracket 4 on the extension portion 202. To improve installation precision, the clip hole 207 in this embodiment is rectangular. When in the clipped state, the second mounting bracket 4 cannot rotate relative to the extension portion 202, thereby improving the installation precision of the second mounting bracket 4.
[0064] In addition, if Figure 7 and Figure 11 As shown in , to improve the positioning of the second mounting bracket 4 on the extension portion 202, two second positioning posts 406 are provided on the top surface of the second mounting bracket 4, each of which is provided with a second positioning hole 208 corresponding to each second positioning post 406. By inserting the second positioning post 406 into the corresponding second positioning hole 208, the second mounting bracket 4 installed along the vertical direction of the vehicle can be positioned, thereby improving the clamping accuracy and clamping efficiency between the clip 401 and the clamping hole 207. A sixth sealing ring 4061 is sleeved on the second positioning post 406 to improve the sealing effect between the second positioning post 406 and the second positioning hole 208.
[0065] In this embodiment, the second mounting bracket 4 is connected to the extension portion 202 via a threaded pair, with a sealing ring interposed between the two. This sealing ring is referred to herein as the third sealing ring. The threaded pair provides a strong fastening force, ensuring a tight connection between the second mounting bracket 4 and the extension portion 202. Furthermore, the third sealing ring effectively prevents water, dust, and other impurities from entering the connection, thereby ensuring the structural reliability of the connection and achieving a satisfactory sealing effect in the dry area of the vehicle body. This avoids the problem of increased space required by traditional plastic nuts.
[0066] Specific structure reference Figure 11 As shown in FIG, the threaded pair includes a plurality of second bolts 402, which are inserted from bottom to top through the second mounting bracket 4 and the extension portion 202, and a second nut 4021, which is threadedly connected to the second bolts 402. A third sealing ring can be mounted on the second bolts 402. The second bolts 402 are arranged in a triangular shape to ensure better connection reliability. Of course, the number and position of the second bolts 402 in this embodiment can still be adjusted according to the actual needs.
[0067] The second nut 4021 in this embodiment is preferably a waterproof nut in the prior art, such as Figure 13 As shown in FIG, a fourth sealing ring 4022 is provided at the bottom or side of the waterproof nut, thereby effectively preventing moisture from entering the connection between the second nut 4021 and the second bolt 402. When the waterproof nut is tightened on the bolt, the fourth sealing ring 4022 thereon is squeezed and deformed, thereby filling the gap between the second nut 4021 and the extension portion 202.
[0068] In this embodiment, the second mounting bracket 4 is flat and block-shaped, with its thickness aligned with the vertical direction of the vehicle. This arrangement allows for effective mounting and connection within a limited space, preventing deformation of the second mounting bracket 4 during a collision, which could cause structural distortion of the body side 2.
[0069] As a feasible implementation method, the second mounting bracket 4 can make the thickness of the second mounting bracket 4 as small as possible while meeting its own structural stiffness requirements and combining the collision safety requirements, thereby providing the rear bumper 1 with the largest possible collision crushing space, thereby helping to improve the collision safety of the vehicle.
[0070] In this embodiment, the first connecting portion includes a first clamping block 302 disposed at the top of the first mounting bracket 3. The first clamping block 302 can be clamped and connected horizontally to the rear bumper 1. The second connecting portion includes a second clamping block 403 disposed at the top of the second mounting bracket 4. The second clamping block 403 can be clamped and connected horizontally to the rear bumper 1. The first clamping block 302 and the second clamping block 403 can be clamped and connected horizontally to the rear bumper 1, making this connection method simple and quick to operate.
[0071] Specifically, if Figure 9 and Figure 12 As shown in FIG, the first mounting bracket 3 is in the shape of an elongated strip arranged along the dividing seam 100, and a plurality of first clamping blocks 302 are provided, spaced apart along the length of the first mounting bracket 3. The second mounting bracket 4 is in the shape of an elongated strip arranged along the dividing seam 100, and a plurality of second clamping blocks 403 are provided, spaced apart along the length of the second mounting bracket 4. Both the first clamping blocks 302 and the second clamping blocks 403 extend horizontally to facilitate horizontal clamping connection with the rear bumper 1.
[0072] like Figure 14 As shown in FIG, a connecting edge 101 extending inwardly from the top of the rear bumper 1 corresponds to the first flange 203. The connecting edge 101 is provided with a plurality of first engaging holes 1011 corresponding one-to-one with each first engaging block 302, and a plurality of second engaging holes 1012 corresponding one-to-one with each second engaging block 403. The multi-point connection formed by the multiple first engaging blocks 302 engaging the first engaging holes 1011, and the multiple second engaging blocks 403 engaging the second engaging holes 1012, can more evenly distribute external forces acting on the rear bumper 1, thereby improving the stability of the connection between the mounting bracket and the rear bumper 1. For example, when the vehicle encounters a bump or collision during driving, the multi-point connection of the multiple first engaging blocks 302 and the multiple second engaging blocks 403 can better withstand the impact force and reduce shaking and deformation of the rear bumper 1.
[0073] Furthermore, the elongated mounting bracket, combined with multiple spaced-apart clips, supports the rear bumper 1 at various locations, enhancing the torsion resistance of the entire mounting structure. This prevents the rear bumper 1 from twisting or deforming when the vehicle turns or is subjected to lateral forces, ensuring the vehicle's appearance and safety. The presence of multiple clips allows the mounting bracket to more precisely adjust the position of the rear bumper 1 during installation. Installers can adjust the connection between the clips and the rear bumper 1 individually, ensuring a tighter fit between the rear bumper 1 and the body side panel 2 at the seam 100, minimizing installation errors.
[0074] In addition, if Figure 9 and Figure 12 As shown in , the first mounting bracket 3 is provided with a first limiting arm 303 and a first supporting rib 304, which respectively abut the upper and lower sides of the connecting edge 101. The second mounting bracket 4 is provided with a second limiting arm 404 and a second supporting rib 405, which respectively abut the upper and lower sides of the connecting edge 101. The first limiting arm 303 and first supporting rib 304 on the first bracket, and the second limiting arm 404 and second supporting rib 405 on the second mounting bracket 4, all help prevent the rear bumper 1 from shaking and shifting in the vertical direction, thereby improving the stability of the connection.
[0075] The first limiting arms 303 are spaced apart along the length of the first mounting bracket 3 and staggered with the first clamping blocks 302. The connecting edge 101 is inserted between each first limiting arm 303 and the top of the first mounting bracket 3, thereby guiding the installation between the first mounting bracket 3 and the rear bumper 1 and improving the clamping efficiency between the first clamping blocks 302 and the corresponding first clamping holes 1011. In some embodiments, a plurality of first support ribs 304 are also spaced apart along the length of the first mounting bracket 3, thereby improving the support and limiting effect of the connecting edge 101.
[0076] like Figure 12 As shown in , the second limiting arms 404 are spaced apart along the length of the second mounting bracket 4 and staggered with the second clamping blocks 403. The connecting edge 101 is inserted between each second limiting arm 404 and the top of the second mounting bracket 4, thereby guiding the installation between the second mounting bracket 4 and the rear bumper 1, thereby improving the clamping efficiency between the second clamping blocks 403 and the corresponding second clamping holes 1012. In some embodiments, a plurality of second support ribs 405 are also spaced apart along the length of the second mounting bracket 4, thereby improving the support and limiting effect of the connecting edge 101.
[0077] In addition, the coordination of the limiting arms and support ribs in this embodiment can disperse the forces acting on the rear bumper 1 to the first mounting bracket 3 and the second mounting bracket 4. When the rear bumper 1 is subjected to a collision from the rear, the limiting arms and support ribs can jointly bear part of the impact force, reducing the deformation of the rear bumper 1 and protecting the vehicle body structure and other components. The coordination of the connecting edge 101 with the limiting arms and support ribs enables precise positioning of the rear bumper 1. During installation, the installer simply inserts the connecting edge 101 of the rear bumper 1 between the limiting arms and support ribs to quickly determine the position of the rear bumper 1, reducing installation errors and improving installation accuracy.
[0078] To enhance the structural strength of the first mounting bracket 3 and the second mounting bracket 4, multiple reinforcing ribs may be provided on both. The reinforcing ribs have a simple structure, are easy to arrange and implement, and provide a good reinforcing effect. In specific implementation, the arrangement, number, and location of the reinforcing ribs can be determined based on the specific requirements.
[0079] The rear bumper mounting structure in this embodiment connects the first mounting bracket 3 to the connecting portion 201 along the left-right direction of the vehicle, and connects the second mounting bracket 4 to the extending portion 202 along the left-right direction of the vehicle. This helps to avoid the influence of part rebound and assembly errors on the gap surface difference between the rear end of the rear bumper 1 and the body side 2, and is more conducive to the sense of refinement between the rear end of the rear bumper 1 and the body side 2 structure, thereby solving the manufacturing and installation defects of the integrated mounting bracket structure in the prior art.
[0080] Furthermore, the front-to-back coordination of the multiple first clamping blocks 302 on the first mounting bracket 3 and the multiple second clamping blocks 403 on the second mounting bracket 4 improves the installation efficiency and precision of the rear bumper 1. Furthermore, the flat second mounting bracket 4 increases the crushing space of the rear bumper 1, thereby improving safety in low-speed collisions.
