[0040] The first embodiment of the utility model provides a rear bumper support structure, such as Figure 1-Figure 3 As shown, the rear bumper support structure includes a support plate 1, which is installed between a rear panel 2 and a rear bumper 3. The support plate 1 is positioned and connected to the rear panel 2 via a convex welding stud 4. The upper part of the support plate 1 is connected to the rear bumper 3 via a clamping structure 5, and the lower part of the support plate 1 is connected to the rear bumper 3 via a fixing structure 6.

[0041] A support plate 1 is provided between the rear bumper 3 and the rear panel 2 to improve the strength of the rear bumper 3; the support plate 1 is fixed to the rear bumper 3 and the rear panel 2 respectively, the support plate 1 and the rear panel 2 are fixed by projection welding studs 4, the support plate 1 and the rear bumper 3 are connected by a clamping structure 5 and a fixing structure 6, and the clamping structure 5 and the fixing structure 6 are fixed at the upper and lower parts of the support plate 1 respectively, which improves the stability of the support plate 1, thereby improving the stability of the rear bumper 3.

[0042] like Figure 3 As shown, a projection welding stud 4 is projection welded on the rear panel 2, and a mounting hole matching the projection welding stud 4 is opened on the support plate 1. The projection welding stud 4 passes through the mounting hole and is connected with the nut 41. The projection welding stud 4 is projection welded on the rear panel 2 in advance. When the support plate 1 is installed on the rear panel 2, the projection welding stud 4 can quickly locate the installation position of the support plate 1. At the same time, the projection welding stud 4 and the nut 41 stably connect the rear panel 2 and the support plate 1.

[0043] like Figure 4 As shown, the support plate 1 includes a transverse support portion 11 and a longitudinal support portion 12, and a plurality of longitudinal support portions 12 are arranged at intervals and connected to the transverse support portion 11, respectively. The support plate 1 is arranged as a transverse support portion 11 and a longitudinal support portion 12 connected to each other, and the transverse support portion 11 and the longitudinal support portion 12 are preferably arranged vertically, and a reinforcing rib 13 is provided at the connection between the transverse support portion 11 and the longitudinal support portion 12. The support plate 1 is arranged as a structure in which the transverse support portion 11 and the longitudinal support portion 12 are connected to each other, which can improve the stability of the support plate 1 and save materials while ensuring strength. When the support plate 1 and the rear panel 2 are positioned and connected, projection welding studs 4 are arranged on the transverse support portion 11 and the longitudinal support portion 12, respectively, to increase the installation points of the rear panel 2 and the support plate 1. When the rear bumper 3 is subjected to excessive pressure, the surface thereof is prevented from being deformed, and the problem of the rear bumper 3 being soft when pressed is solved.

[0044] In some embodiments, five projection welding bolts are arranged in the transverse support portion 11 , and at least one projection welding bolt is arranged in each longitudinal support portion 12 .

[0045] like Figure 2 , Figure 3 and Figure 5As shown, the support plate 1 is provided with a connection portion 14 protruding toward the rear panel 2, the connection portion 14 is provided with a mounting hole, and a connection groove 15 is formed on the side of the connection portion 14 facing the rear bumper 3. After the projection welding stud 4 passes through the mounting hole, it is connected with the nut 41 in the connection groove 15. The number of the connection portions 14 is consistent with the number of the projection welding stud 4, and the position of the connection portion 14 matches the installation position of the projection welding nut 41. The rear panel 2 and the support plate 1 are connected by the projection welding stud 4, and the projection welding stud 4 covers the mounting hole, intercepts the passage between the support plate 1 and the bumper, and prevents rainwater from entering the cabin; the projection welding stud 4 and the nut 41 are accommodated in the connection groove 15, which can save space and make the structure more compact.

[0046] The bottom of the connecting groove 15 forms a mounting surface, and the mounting surface and the notch of the connecting groove 15 are connected by spaced connecting ribs 16. The connecting ribs 16 are arranged circumferentially along the connecting groove 15, and the connecting ribs 16 are arranged to form a hollow structure at the notch of the connecting portion 14, so that the collision absorption capability is stronger in the case of a low-speed collision.

[0047] In some embodiments, six connecting ribs 16 are arranged at intervals.

[0048] In some other embodiments, the connecting rib 16 has a step portion 17 to further enhance the ability to absorb collisions during low-speed collisions.

[0049] The support plate 1 is preferably made of plastic material to reduce the weight of the vehicle.

[0050] like Figure 6 and Figure 7 As shown, the clamping structure 5 includes a clamping plate 51 and a first clamping hole 52. The clamping plate 51 is provided on the side of the rear bumper 3 facing the support plate 1, and the first clamping hole 52 is provided on the support plate 1. The clamping plate 51 is also provided with a second clamping hole 53, and the support plate 1 is provided with a first clamping portion 54 matching the second clamping hole 53. When the rear bumper 3 and the upper part of the support plate 1 are clamped, the clamping plate 51 extends into the first clamping hole 52 and the first clamping portion 54 extends into the second clamping hole 53 and abuts against the side wall of the second clamping hole 53. The clamping plate 51, the first clamping hole 52, the second clamping hole 53 and the first clamping portion 54 cooperate with each other to tightly connect the rear bumper 3 and the upper part of the support plate 1, thereby ensuring the connection stability between the rear bumper 3 and the support plate 1.

[0051] In some other embodiments, the clamping structure 5 further includes a clamping groove 55 and a second clamping portion 56. The clamping groove 55 is provided on the side of the rear bumper 3 facing the support plate 1. The second clamping portion 56 is provided on the support plate 1. The second clamping portion 56 is clamped in the clamping groove 55. A groove wall on one side of the clamping groove 55 forms a clamping plate 51. The upper part of the rear bumper 3 has a flange extending toward the support plate 1. The flange and the clamping plate 51 form a clamping groove 55. The second clamping portion 56 on the support plate 1 cooperates with the clamping groove 55, so that the clamping between the rear bumper 3 and the support plate 1 is stable, and the working pressure of the clamping plate 51 and the first clamping portion 54 is reduced.

[0052] like Figure 8 As shown, the fixing structure 6 includes a leaf nut 61 and a screw 62. The leaf nut 61 is mounted on the support plate 1. The screw 62 passes through the rear bumper 3 and the support plate 1 in sequence and is fixed by the leaf nut 61.

The problem of the rear bumper 3 sagging and affecting the clearance with the back door is solved. At the same time, the support plate 1 supports the entire rear bumper 3, and the installation stability is good.

[0053] During installation, the rear panel 2 is installed on the vehicle body, and then the projection welding studs 4 pre-projection-welded on the rear panel 2 are passed through the installation holes and fixedly connected with the nuts 41, and then the connection between the support plate 1 and the rear bumper 3 is completed through the clamping structure 5 and the fixing structure 6. When the support plate 1 is installed on the rear panel 2, while the projection welding studs 4 pass through the projection welding nuts 41, the positioning posts 7 on the side of the support plate 1 facing the rear panel 2 extend into the positioning holes on the rear panel 2 that match the positioning posts 7. In some embodiments, three positioning posts 7 are provided, one of which is provided at the middle position of the transverse support portion 11, playing the main positioning role, and realizing Y-direction and Z-direction positioning; the other two positioning posts 7 are provided on both sides of the main positioning post 7, realizing Z-direction positioning; the projection welding studs 4 and projection welding nuts 41 provided on the longitudinal support portion 12 not only play the fixing role, but also realize Y-direction positioning.
