[0041] To solve the above-mentioned technical problems, in the embodiments of this application, reference is made to... Figure 1 This application provides a rear floor assembly having a first direction X, a second direction Y, and a third direction Z that intersect each other. For example, the rear floor assembly has a first direction X, a second direction Y, and a third direction Z that are perpendicular to each other. Here, "perpendicular" refers to a state where the angle formed by two lines, a line and a surface, or a surface is 89° to 91°.
[0042] Specifically, refer to Figure 1 , Figure 2 and Figure 3 The rear floor assembly includes: beam frame 100 and spare tire panel assembly 200.
[0043] The beam frame 100 includes: longitudinal beams 110 and first crossbeams 120. At least two longitudinal beams 110 are provided, and the at least two longitudinal beams 110 are spaced apart in a first direction X. The first crossbeams 120 extend along the first direction X and are connected between two adjacent longitudinal beams 110. The spare tire panel assembly 200 is connected to the side of the longitudinal beams 110 near the first crossbeams 120.
[0044] Among them, the longitudinal beam 110 and the first cross beam 120 are integrally formed by high pressure casting, but not limited to this.
[0045] Specifically, a first seat mounting point 111 is provided on the side of the longitudinal beam 110 near the first crossbeam 120, and a second seat mounting point 121 is provided on the side of the first crossbeam 120 near the longitudinal beam 110. The first seat mounting point 111 and the second seat mounting point 121 are configured to mount seats for different vehicle models. For example, the first seat mounting point 111 is configured to mount the second-row seats of a multi-purpose vehicle (MPV), and the second seat mounting point 121 is configured to mount the second-row seats of a sport utility vehicle (SUV).
[0046] The first seat mounting point 111 and the second seat mounting point 121 are threaded holes, but are not limited to this.
[0047] Understandably, this application sets a first seat mounting point 111 on the longitudinal beam 110 and a second seat mounting point 121 on the first cross beam 120 to install seats of different vehicle models using the first seat mounting point 111 and the second seat mounting point 121. This maximizes the sharing of parts among different vehicle models, adapts to the changing needs of different vehicle models, improves the platform compatibility of the beam frame 100, and helps reduce the R&D cost and development cycle of the beam frame 100 for different vehicle models. At the same time, it helps simplify the production line of the beam frame 100 for different vehicle models, facilitates the use of the same mold to process the beam frame 100 for different vehicle models, shortens the mold development cycle of the beam frame 100, and reduces the mold development cost of the beam frame 100.
[0048] In some embodiments, multiple first seat mounting points 111 are provided, with each first seat mounting point 111 located on a corresponding longitudinal beam 110; meanwhile, some of the first seat mounting points 111 are formed by welding mounting brackets onto the longitudinal beam 110.
[0049] Multiple second seat mounting points 121 are provided. Each second seat mounting point 121 is located on both sides of the first crossbeam 120 that are opposite each other in the first direction X. The multiple second seat mounting points 121 are evenly distributed on the first crossbeam 120 so that the force applied to the first crossbeam 120 after the seat is installed on the second seat mounting point 121 is evenly distributed, so as to avoid damage to the first crossbeam 120 and extend the service life of the first crossbeam 120.
[0050] In some embodiments, refer to Figure 2 and Figure 3 The longitudinal beam 110 has a first mounting surface 112, and the first crossbeam 120 has a second mounting surface 122. The first mounting surface 112 and the second mounting surface 122 are arranged sequentially in the second direction Y, and the first mounting surface 112 and the second mounting surface 122 are staggered in the third direction Z. The first seat mounting point 111 is located on the first mounting surface 112, and the second seat mounting point 121 is located on the second mounting surface 122.
[0051] Understandably, this application arranges the first mounting surface 112 and the second mounting surface 122 sequentially in the second direction Y, and the first mounting surface 112 and the second mounting surface 122 are staggered in the third direction Z, in order to meet the installation height requirements of seats of different vehicle models, adapt to the changing requirements of different vehicle models, improve the platform compatibility of the beam frame 100, help reduce the R&D cost and R&D cycle of the beam frame 100 for different vehicle models, and shorten the mold development cycle of the beam frame 100, thereby reducing the mold development cost of the beam frame 100.
[0052] In some embodiments, refer to Figure 2 The first mounting surface 112 includes a first sub-surface 1121, a second sub-surface 1122, and a third sub-surface 1123 connected sequentially in the second direction Y. A first seat mounting point 111 is located on the second sub-surface 1122. The first sub-surface 1121 and the second sub-surface 1122 are arranged at an angle to each other, and the second sub-surface 1122 and the third sub-surface 1123 are arranged at an angle to each other. This serves as the mounting surface for the second-row seats of a multi-purpose vehicle (MPV) and also provides space for the second-row sliding rails and carpets of a sport utility vehicle (SUV). This further maximizes the sharing of parts among different vehicle models, adapts to the changing needs of different vehicle models, improves the platform compatibility of the beam frame 100, helps reduce the R&D cost and development cycle of the beam frame 100 for different vehicle models, and shortens the mold development cycle and reduces the mold development cost of the beam frame 100.
[0053] For example, the rear floor assembly also has a reference plane perpendicular to the first direction X, and the first sub-surface 1121, the second sub-surface 1122 and the third sub-surface 1123 are S-shaped when projected onto the reference plane along the first direction X, but are not limited thereto.
[0054] In some embodiments, refer to Figure 2 , Figure 3 , Figure 7 and Figure 8 The longitudinal beam 110 has a first mounting point 114 on the side near the first cross beam 120. The first mounting point 114 is configured to install the seat belt of the second row of seats in a sport utility vehicle (SUV).
[0055] In some embodiments, refer to Figure 2 , Figure 3 , Figure 7 and Figure 8 The beam frame 100 also includes a second crossbeam 130, which extends along the first direction X, connects two adjacent longitudinal beams 110, and is spaced apart from the first crossbeam 120 in the second direction Y.
[0056] The longitudinal beam 110 and the second transverse beam 130 are integrally formed by high-pressure casting, but are not limited thereto. For example, the outer wall surface of the beam frame 100 on the third direction Z is mainly formed by the fixed mold of the die-casting mold, the outer wall surface of the beam frame 100 on the other side of the third direction Z is mainly formed by the moving mold of the die-casting mold, the structural features of the beam frame 100 on the first direction Z are formed by the slider of the die-casting mold, and the structural features of the beam frame 100 on the other side of the first direction Z are formed by the slider of the die-casting mold.
[0057] Specifically, a third seat mounting point 113 is provided on the side of the longitudinal beam 110 near the second crossbeam 130, and a fourth seat mounting point 131 is provided on the side of the second crossbeam 130 near the longitudinal beam 110. The third seat mounting point 113 and the fourth seat mounting point 131 are configured to mount seats for different vehicle models. For example, the third seat mounting point 113 is configured to mount the third-row seats of a multi-purpose vehicle (MPV), and the fourth seat mounting point 131 is configured to mount the third-row seats of a sport utility vehicle (SUV).
[0058] Among them, the third seat mounting point 113 and the fourth seat mounting point 131 are threaded holes, but are not limited to this.
[0059] This application, by setting a third seat mounting point 113 on the longitudinal beam 110 and a fourth seat mounting point 131 on the second cross beam 130, further maximizes the sharing of parts among different vehicle models, adapts to the changing needs of different vehicle models, improves the platform compatibility of the beam frame 100, and helps reduce the R&D cost and development cycle of the beam frame 100 for different vehicle models. At the same time, it helps simplify the production line of the beam frame 100 for different vehicle models, facilitates the use of the same mold to process the beam frame 100 for different vehicle models, shortens the mold development cycle of the beam frame 100, and reduces the mold development cost of the beam frame 100.
[0060] In some embodiments, refer to Figure 2 , Figure 3 , Figure 7 and Figure 8 When the rear floor assembly is applied to a sport utility vehicle (SUV), a second mounting point 115 is provided on the side of the longitudinal beam 110 near the second crossbeam 130, and a first mounting point 114 is configured to mount the seat belt of the third row of seats in the sport utility vehicle.
[0061] When the rear floor assembly is applied to a multi-purpose vehicle (MPV), the fourth seat mounting point 131 is also configured to mount the seat belts of the third-row seats of the MPV.
[0062] In some embodiments, refer to Figure 4 and Figure 5 The beam frame 100 also includes multiple positioning parts 140, each positioning part 140 being respectively disposed on both sides of the longitudinal beam 110 arranged opposite each other in the second direction Y. Each positioning part 140 is provided with a positioning hole 141, which is configured to realize the positioning and fixing of the beam frame 100 in different vehicle models, so as to further realize the maximum sharing of parts in different vehicle models, adapt to the changing needs of different vehicle models, improve the platform compatibility of the beam frame 100, and help reduce the R&D cost and R&D cycle of the beam frame 100 for different vehicle models; at the same time, it helps to simplify the production line of the beam frame 100 for different vehicle models, and helps to use the same mold to process the beam frame 100 for different vehicle models, shorten the mold development cycle of the beam frame 100, and reduce the mold development cost of the beam frame 100.
[0063] In some embodiments, refer to 1, Figure 2 and Figure 3 The beam frame 100 also includes a first reinforcing part 150, which is connected to the longitudinal beam 110 and is located between the first crossbeam 120 and the second crossbeam 130.
[0064] Among them, the beam 100 with the first reinforcing part 150 is used in sport utility vehicles (SUVs).
[0065] Specifically, the first reinforcing part 150 includes: a first sub-reinforcing part 151 and a second sub-reinforcing part 152. The first sub-reinforcing part 151 extends along the second direction Y. At least two second sub-reinforcing parts 152 are provided. Each second sub-reinforcing part 152 extends along the first direction X. Each second sub-reinforcing part 152 is connected to the two opposite sides of the first sub-reinforcing part 151 in the second direction Y. The side of each second sub-reinforcing part 152 away from the first sub-reinforcing part 151 is connected to the longitudinal beam 110. That is, the first reinforcing part 150 is arranged in a convex shape to maximize the size of the first reinforcing part 150 in the first direction X. This allows the beam frame 100 to have multiple force transmission paths with other structures, effectively ensuring the torsional mode of the whole vehicle and improving the rigidity of the chassis mounting point of the vehicle.
[0066] The first sub-reinforcing part 151 and the second sub-reinforcing part 152 are integrally formed by high-pressure casting, but are not limited to this.
[0067] In some embodiments, refer to Figure 6 , Figure 7 and Figure 8 The beam frame 100 also includes a second reinforcing part 160, which is connected to the longitudinal beam 110 and is located between the first crossbeam 120 and the second crossbeam 130.
[0068] Among them, the beam 100 with a second reinforcing section 160 is used in multi-purpose vehicles (MPVs).
[0069] Specifically, the second reinforcing part 160 includes a third sub-reinforcing part 161 and a fourth sub-reinforcing part 162. The third sub-reinforcing part 161 extends along the second direction Y, and the fourth sub-reinforcing part 162 extends along the first direction X. The fourth sub-reinforcing part 162 is connected to one side of the third sub-reinforcing part 161 in the second direction Y. The third sub-reinforcing part 161 and the fourth sub-reinforcing part 162 are respectively connected to the longitudinal beam 110.
[0070] The third sub-reinforcing part 161 and the fourth sub-reinforcing part 162 are integrally formed by high-pressure casting, but are not limited to this.
[0071] It is understandable that the third-row seats of a multi-purpose vehicle can be folded and stored in the spare tire compartment. Therefore, by providing the second reinforcing part 160, the space occupied by the second reinforcing part 160 in the first direction X is reduced, ensuring the efficient folding and flipping of the third-row seats of the multi-purpose vehicle, while effectively ensuring the torsional mode of the whole vehicle and improving the rigidity of the chassis mounting point of the vehicle.
[0072] In some embodiments, the beam frame 100 for a multi-purpose vehicle and the beam frame 100 for a sport utility vehicle differ only in the structure of the reinforcing section, while the structures of other areas are identical. In actual manufacturing, the mold core of the casting mold for the beam frame 100 can be disassembled into different inserts. By replacing certain inserts in the mold, the same mold can be used to produce both the beam frame 100 for a multi-purpose vehicle and the beam frame 100 for a sport utility vehicle, thus achieving mold sharing.
[0073] For example, in the formal production process, a certain number of beam frames 100 for multi-purpose vehicles can be produced using molds first. After the planned output is reached, the staff can replace the differentiated inserts in the molds and then use the same molds to produce beam frames 100 for sports multi-purpose vehicles, thereby improving the utilization rate and economy of the molds.

[0076] Battery pack mounting point 172 is located on the first crossbeam 120, and battery pack mounting point 172 is configured to mount the battery pack.
[0077] Multiple rear subframe mounting points 173 are provided, and the multiple rear subframe mounting points 173 are respectively provided on both sides of the longitudinal beam 110 in the second direction Y. The rear subframe mounting points 173 are configured to install the rear subframe system of the vehicle. At the same time, some of the rear subframe mounting points 173 are configured to perform rough positioning for the installation of the rear subframe chassis system. Meanwhile, the longitudinal beam 110 is provided with reinforcing ribs at the rear subframe mounting points 173 to improve the rigidity of the longitudinal beam 110 at the rear subframe mounting points 173.
