[0039] Embodiment 1

[0040] As Figure 1 shown, this embodiment provides a rear floor skeleton reinforcement structure, including a support member 1 and a reinforcement member 2. The support seat 1 has an installation area 14. The support seat 1 is installed in the rear floor skeleton, the reinforcement member 2 is installed in the installation area 14, and a positioning member 3 is provided between the reinforcement member 2 and the support seat 1 to define the relative position between the support seat 1 and the reinforcement member 2.

[0041] During actual use, the support base 1 is installed in the longitudinal beam of the rear floor skeleton. The reinforcing member 2 is used to ensure the support strength of the support base 1, ensure the anti-collision strength of the longitudinal beam, further improve the anti-collision strength of the vehicle body side, and ensure the personal safety of passengers. In this application, the relative position between the reinforcing member 2 and the support base 1 is restricted by the positioning member 3, so that when the support base 1 installed in the rear floor skeleton is impacted externally, the stability between the reinforcing member 2 and the support base 1 can be ensured, and the anti-collision strength of the rear floor skeleton is further improved.

[0042] As Figures 2 to 4 shown, in a specific example provided in this embodiment, the support base 1 includes a bottom plate 11, and a first support plate 12 and a second support plate 13 bent upward along opposite sides of the bottom plate 11; a connecting portion 111 for connecting with the rear floor skeleton is provided on the bottom plate 11; an installation area 14 for installing the positioning member 3 and the reinforcing member 2 is formed between the first support plate 12 and the second support plate 13. The reinforcing member 2 includes a reinforcing plate 21, and a first auxiliary plate 22 and a second auxiliary plate 23 bent downward along opposite sides of the reinforcing plate 21 respectively; the positioning member 3 is a positioning post, the bottom of the positioning post is fixed on the bottom plate 11, and the other end is connected to the reinforcing plate 21.

[0043] In this embodiment, the support base 1 has a U-shaped structure, the reinforcing member 2 has an inverted U-shaped structure, and the reinforcing structure formed by combining the reinforcing member 2 and the support base, on the one hand, reduces the weight of the floor skeleton reinforcing structure, and on the other hand, the formed multi-layer anti-collision structure ensures the anti-collision strength of the floor skeleton reinforcing structure. It should be noted that in other embodiments, the support base 1 is a box structure with an open top, and an installation area 14 is provided inside the box; the positioning member 3 includes a plurality of positioning rods located in the installation area 14 and fixed to the bottom of the box; the reinforcing member 2 is arranged at the opening of the box, and an installation portion 211 for cooperating with the positioning rods is provided on the reinforcing member 2. Thus, this application does not limit the specific structures of the support base 1, the positioning member 3, and the reinforcing member 2.

[0044] Furthermore, in this embodiment, the connecting portion 111 includes a connecting hole provided on the bottom plate 11; the bottom of the positioning post is provided with a positioning hole 31 (see Figure 6 ), and a bolt passes through the positioning hole and the connecting hole to fix the positioning member 3 to the bottom plate 11; a limiting hole 211 is provided on the reinforcing plate 21 for the top of the positioning post to pass through.

[0045] During the actual installation process, align the connection holes on the bottom plate 11 with the installation holes on the longitudinal beam of the rear floor skeleton. Then, align the positioning holes 31 on the positioning posts placed within the installation area 14 with the connection holes, and connect the positioning posts, the bottom plate 11, and the longitudinal beam of the rear floor skeleton together with bolts. Move the reinforcement plate 21 so that the top of the positioning post passes through the limit hole on the reinforcement plate 21, and the front and rear sides of the first auxiliary plate 22 and the second auxiliary plate 23 are respectively abutted against the first support plate 12 and the second support plate 13. When the longitudinal beam of the rear floor skeleton is impacted, the longitudinal beam of the rear floor skeleton transfers the extrusion force to the first support plate 12 and the second support plate 13. The reinforcement plate 21, the first auxiliary plate 22, and the second auxiliary plate 23 cooperate to support the first support plate 12 and the second support plate 13, preventing the first support plate 12 and the second support plate 13 from deforming and ensuring the strength of the longitudinal beam of the rear floor skeleton.

[0046] In this embodiment, the positioning member 3 can define the relative positions of the reinforcing member 2 and the support base 1, ensuring the connection stability between the support member and the support base 1 and further improving the anti-collision strength of the rear floor skeleton assembly. In other embodiments, the bottom plate 11 is welded inside the longitudinal beam of the rear floor skeleton, the bottom of the positioning member 3 is welded to the bottom plate 21, and the reinforcing member 2 and the positioning member 3 are in plug-in limit. Thus, the present application does not limit the specific connection structure between the bottom plate and the rear floor skeleton, the specific connection structure between the positioning member 3 and the support base 1, and the specific connection structure between the reinforcing member 2 and the positioning member 3, which can be selected and set according to the actual situation.

[0047] As Figures 5 to 7 shown, in a specific example provided in this embodiment, a first pressure-reducing plate 212 and a second pressure-reducing plate 213 are respectively bent upward at the side ends of the reinforcement plate 21 opposite to the first support plate 12 and the second support plate 13; a first arc-shaped plate 214 and a second arc-shaped plate 215 are respectively provided between the first pressure-reducing plate 212 and the second pressure-reducing plate 213 and the reinforcement plate 21. The first pressure-reducing plate 212 and the second pressure-reducing plate 213 ensure the support strength of the reinforcement plate 21 for the first support plate 12 and the second support plate 13. The first arc-shaped plate 214 between the first pressure-reducing plate 212 and the reinforcement plate 21 improves the compressive strength between the first pressure-reducing plate 212 and the reinforcement plate 21, and the second arc-shaped plate 215 between the second pressure-reducing plate 213 and the reinforcement plate 21 improves the compressive strength between the second pressure-reducing plate 213 and the reinforcement plate 21, further improving the support strength of the reinforcement plate 21 for the first support plate 12 and the second support plate 13 and ensuring the support strength of the rear floor skeleton reinforcement structure for the rear floor skeleton.

[0048] A specific example provided by this embodiment is that on one side of the first auxiliary plate 22 close to the first support plate 12 and on one side close to the second support plate 13, there are respectively provided first auxiliary pressure relief plates 221 extending in a direction away from the second auxiliary plate 23. There is a first auxiliary arc panel 222 between the first auxiliary pressure relief plate 221 and the first auxiliary plate 22; on one side of the second auxiliary plate 23 close to the first support plate 12 and on one side close to the second support plate 13, there are respectively provided second auxiliary pressure relief plates 231 extending in a direction away from the first auxiliary plate 22. There is a second auxiliary arc panel 232 between the second auxiliary pressure relief plate 231 and the second auxiliary plate 23. Specifically, there is a first arc surface transition section 224 between the first auxiliary plate 22 and the reinforcing plate 21, and a second arc surface transition section 234 between the second auxiliary plate 23 and the reinforcing plate 21. The first arc surface transition section 224 and the second arc surface transition section 234 are respectively used to increase the connection strength between the first auxiliary plate 22 and the reinforcing plate 21 and between the second auxiliary plate 23 and the reinforcing plate 21.

[0049] During actual use, the first auxiliary pressure relief plate 221 and the second auxiliary pressure relief plate 231 are respectively used to improve the support strength of the first auxiliary plate 22 and the second auxiliary plate 23 for the first support plate 12 and the second support plate 13. The first auxiliary arc panel 222 increases the compressive strength between the first auxiliary pressure relief plate 221 and the first auxiliary plate 22, and the second auxiliary arc panel 232 increases the compressive strength between the second auxiliary pressure relief plate 231 and the second auxiliary plate 23, further improving the compressive strength of the reinforcing member 2 between the first support plate 12 and the second support plate 13, and ensuring the support strength of the rear floor skeleton reinforcement structure for the rear floor skeleton.

[0050] A specific example provided by this embodiment is that on at least one side of the first auxiliary plate 22 relative to the bottom plate 11, there is at least provided a first auxiliary reinforcing plate 223 extending in a direction away from the second auxiliary plate 23; on at least one side of the second auxiliary plate 23 relative to the bottom plate 11, there is at least provided a second auxiliary reinforcing plate 233 extending in a direction away from the first auxiliary plate 22.

[0051] During actual use, the first auxiliary plate 22 is subjected to the acting forces of the first auxiliary pressure-reducing plates 221 on both sides, and the second auxiliary plate 23 is subjected to the acting forces of the second auxiliary pressure-reducing plates 231 on both sides. The first auxiliary reinforcing plate 223 and the second auxiliary reinforcing plate 233 are respectively used to increase the compressive strength of the first auxiliary plate 22 and the second auxiliary plate 23, and improve the overall strength of the reinforcing member 2. It should be noted that in this embodiment, the first auxiliary plate 22 and the second auxiliary plate 23 are respectively provided with a first arc-shaped protrusion 226 and a second arc-shaped protrusion 236, which are used to increase the bending strength of the first auxiliary plate 22 and the second auxiliary plate 23, and improve the bending strength of the support member.

[0052] Furthermore, a first reinforcing rib 225 and a second reinforcing rib 235 are respectively provided on the first auxiliary reinforcing plate 223 and the second auxiliary reinforcing plate 233. Specifically, the first reinforcing rib 225 and the second reinforcing rib 235 are respectively strip-shaped protrusion portions formed by being recessed upward on the first auxiliary reinforcing plate 223 and the second auxiliary reinforcing plate 233. The strip-shaped protrusion portions are located in the middle of the first auxiliary reinforcing plate 223 and the second auxiliary reinforcing plate 233. The extension lines of the strip-shaped protrusion portions on the first auxiliary reinforcing plate 223 and the second auxiliary reinforcing plate 233 are on the same straight line. The reinforcing ribs are used to increase the anti-extrusion ability of the first auxiliary reinforcing plate 223 and the second auxiliary reinforcing plate 233, and further increase the overall strength of the reinforcing member 2.
