[0030] Please refer to Figure 1 and Figure 2 , Figure 1 is a schematic structural diagram of an embodiment of the body assembly of the present application, Figure 2 is Figure 1 a schematic structural diagram of area A of the body assembly shown in

[0031] In one embodiment, a vehicle includes a body assembly 10. The body assembly 10 has a longitudinal direction X, a width direction Y, and a height direction Z, and the longitudinal direction X, the width direction Y, and the height direction Z are perpendicular to each other pairwise. The body assembly 10 includes a front bulkhead crossbeam assembly 15 and a rear floor assembly 16 distributed along the longitudinal direction X, and the front bulkhead crossbeam assembly 15 and the rear floor assembly 16 are connected by a sill assembly 11. On both sides of the body assembly 10 in the width direction Y, sill assemblies 11 are respectively provided. The front bulkhead crossbeam assembly 15, the rear floor assembly 16, and the sill assembly 11 enclose to form the skeleton of the body assembly 10.

[0032] The body assembly 10 further includes a front floor panel 12. In the height direction Z, the front floor panel 12 is disposed above the skeleton of the body assembly 10. The body assembly 10 further includes a seat mounting assembly 13, and the seat mounting assembly 13 is stacked on the front floor panel 12. The seat mounting assembly 13 is used for mounting a seat. In the height direction Z, the seat mounting assembly 13 is located above the front floor panel 12. An avoidance groove 121 is provided at an edge of the front floor panel 12 close to the sill assembly 11, and at least a part of the seat mounting assembly 13 is embedded in the avoidance groove 121, and the seat mounting assembly 13 is connected to the sill assembly 11.

[0033] By the above method, an avoidance groove 121 is provided at an edge of the front floor panel 12 of this embodiment close to the sill assembly 11, and at least a part of the seat mounting assembly 13 is embedded in the avoidance groove 121, so as to allow a part of the seat mounting assembly 13 located in the avoidance groove 121 to have a larger cross-sectional height, directly improving the side anti-collision stiffness of the body assembly 10, and improving the side anti-collision performance of the body assembly 10 through the seat mounting assembly 13, which is beneficial to reducing the lateral deformation of the occupant compartment and protecting the safety of the driver and passengers to the greatest extent. Moreover, the seat mounting assembly 13 is directly connected to the sill assembly 11 to form a force transmission path of side collision impact force - sill assembly 11 - seat mounting assembly 13 - skeleton. By optimizing the force transmission path in this embodiment, the side anti-collision performance of the body assembly 10 can be further improved. In addition, the design that at least a part of the seat mounting assembly 13 of this embodiment is embedded in the avoidance groove 121 can reduce the risk of loosening of the seat mounting points, maintain the connection reliability during long-term use, and ensure the durability of the side anti-collision performance of the body assembly 10.

[0034] It should be noted that the front bulkhead crossbeam assembly 15 includes a torque box and a front bulkhead middle crossbeam. On both the left and right sides of the body assembly 10 in the width direction Y, torque boxes are provided on both sides of the front bulkhead crossbeam assembly 15. The torque boxes are aluminum alloy die-castings and are S-shaped in the front-rear direction. The front bulkhead middle crossbeam is transversely arranged between the torque boxes on the left and right sides and connects the torque boxes on the left and right sides. A lapping step is provided on the side of the connected front bulkhead crossbeam assembly 15 facing the front floor panel 12, and the step surface of the lapping step is the lapping surface of the front floor panel 12.

[0035] The rear floor assembly 16 is composed of an integrally formed rear floor skeleton and a rear floor panel. The rear floor skeleton is a trough-shaped structure with an upward opening, and a lapping step is provided at the front of the rear floor skeleton. The rear floor panel is arranged above the integrally formed rear floor skeleton, and the rear floor panel and the rear floor skeleton are fixedly connected by spot welding. The lapping step of the rear floor assembly 16 is higher than that of the front crossbeam assembly 15. The front floor panel 12 has an overall Z-shaped cross-section structure that is lower at the front and higher at the rear, so that the front and rear of the front floor panel 12 can be respectively connected to the front crossbeam assembly 15 and the rear floor assembly 16.

[0036] In one embodiment, with the continuous development of new energy vehicles, the automotive market has become increasingly diversified. Vehicle models have developed from mass-produced to personalized customization, from SUV models to crossover models, coupe models, etc., to meet the needs of different consumers. Compared with traditional fuel vehicles, a battery pack needs to be arranged under the front floor panel for new energy vehicle models. On the premise of meeting the cruising range, generally, high-height single batteries are used, and the overall vehicle height is also higher; while for sedan models, more attention is paid to the appearance styling, and a low-slung and personalized styling is required, often requiring specially designed low single batteries to reduce the height of the battery pack, thereby reducing the overall vehicle height.

[0037] The vehicle of the embodiment of the present application can be a new energy vehicle, etc. Please refer to Figure 3 and Figure 4 simultaneously. The body assembly 10 further includes a battery pack 14, and the battery pack 14 is located on one side of the front floor panel 12 in the Z direction of the height of the body assembly 10. In the Z direction of the height, the battery pack 14 is assembled from below to the lower part of the skeleton of the body assembly 10. The front floor panel 12 is located above the battery pack 14, and the front floor panel 12 cooperates with the skeleton of the body assembly 10 to achieve the sealing of the upper part of the battery pack 14.

[0038] Specifically, please refer to Figure 5 simultaneously. The front floor panel 12 includes a panel main body 122 and a first lapping portion 123. The first lapping portion 123 is connected to the edge of the panel main body 122, and the first lapping portion 123 is provided with an avoidance groove 121. The first lapping portion 123 surrounds the outer peripheral edge of the panel main body 122. The first lapping portions 123 at the front and rear of the front floor panel 12 are respectively matched and fitted with the lapping steps of the front crossbeam assembly 15 and the lapping steps of the rear floor assembly 16. The height of the lapping step of the front crossbeam assembly 15 is set to match the highest height of the single battery 142 of the battery pack 14.

[0039] The first overlapping portion 123 is located on the side of the panel main body 122 away from the battery pack 14. The panel main body 122 and the first overlapping portion 123 cooperate to enclose a concave pit 124. The depth of the concave pit 124 matches the height of the single battery 142 in the battery pack 14. In this embodiment, the selection and adaptation are carried out according to the requirements of the overall vehicle styling height for the height of the single battery 142, and the depth of the concave pit 124 is determined by the height of the single battery 142. This embodiment provides a platform body structure solution with a high degree of generality. By determining the depth of the concave pit 124 of the front floor panel 12 according to the height of the single battery 142, it can be compatible with the platform expansion of models with high single batteries 142 and low single batteries 142. When adapting to SUV models and low-slung coupe models, the body assembly 10 of this embodiment has good generalization and performance consistency.

[0040] Specifically, in the height direction Z of the body assembly 10, the distance between the panel main body 122 of the front floor panel 12 and the battery tray 143 of the battery pack 14 matches the height of the single battery 142. In this embodiment, the selection and adaptation are carried out according to the requirements of the overall vehicle styling height for the height of the single battery 142, and the distance between the panel main body 122 and the battery tray 143 is determined by the height of the single battery 142. This embodiment provides a platform body structure solution with a high degree of generality. By determining the distance between the panel main body 122 and the battery tray 143 according to the height of the single battery 142, it can be compatible with the platform expansion of models with high single batteries 142 and low single batteries 142. When adapting to SUV models and low-slung coupe models, the body assembly 10 of this embodiment has good generalization and performance consistency.

[0041] Please refer to Figures 6 to 8 , Figure 6 which is a schematic structural diagram of an embodiment of the reinforcement member of the present application, Figure 7 is Figure 6 a schematic structural diagram of the reinforcement member from another perspective shown, Figure 8 which is a schematic structural diagram of an embodiment of the sill beam of the present application.

[0042] In one embodiment, the sill assembly 11 has a second overlapping portion 111. The second overlapping portion 111 is provided with a mating groove 112. The portion of the second overlapping portion 111 adjacent to the mating groove 112 and the portion of the first overlapping portion 123 adjacent to the avoidance groove 121 are overlapped with each other.

[0043] In the above manner, on the basis of setting the avoidance groove 121 on the front floor panel 12, the second overlap portion 111 of the door sill assembly 11 is matched with the first overlap portion 123 of the front floor panel 12 in shape, so that the first overlap portion 123 and the second overlap portion 111 are closely fitted, further ensuring that the front floor panel 12 cooperates with the frame of the vehicle body assembly 10 to achieve the sealing of the upper part of the battery pack 14. In addition, the avoidance groove 121 of the first overlap portion 123 and the matching groove 112 of the second overlap portion 111 form a "boss-groove" bite structure, which can extend the path length of external impurities invading the battery pack 14, and the external impurities need to pass through multiple bending paths to invade the battery pack 14. In addition, when the vehicle is driving, the body assembly 10 is prone to micro-deformation due to bumps on the road. The interlocking overlap structure formed by the first overlap portion 123 and the second overlap portion 111 of the present embodiment can absorb the displacement and avoid as much as possible the problem of traditional plane overlap that easily leads to separation of the front floor panel 12 and the door sill assembly 11, thereby ensuring the reliability of the sealing of the battery pack 14 during long-term use.

[0044] Further, the threshold assembly 11 includes a threshold beam 113 and a reinforcement member 114. The threshold beam 113 has a mounting groove 1131. The reinforcement member 114 is embedded in the mounting groove 1131. The second overlapping portion 111 includes a first overlapping sub-portion 1111 and a second overlapping sub-portion 1112, wherein the first overlapping sub-portion 1111 is connected to a side of the threshold beam 113 close to the front floor panel 12, and the second overlapping sub-portion 1112 is connected to a side of the reinforcement member 114 close to the front floor panel 12, and the second overlapping sub-portion 1112 is provided with a matching groove 112.

[0045] In the width direction Y, a threshold beam 113 of an aluminum alloy extruded profile is provided on both sides of the front floor panel 12. The threshold beam 113 is a multi-cavity uniform cross-section structure. The front and rear ends of the threshold beam 113 are connected to the front wall cross beam assembly 15 and the rear floor assembly 16. The threshold beam 113 is provided with a second overlap portion 111 on the side facing the front floor panel 12. The second overlap portion 111 is consistent with or close to the overlap step of the front wall cross beam assembly 15. The second overlap portion 111 of the threshold beam 113 and the overlap step of the front wall cross beam assembly 15 overlap and fit with the first overlap portion 123 at the edge of the front floor panel 12.

[0046] In this embodiment, at the position of the sill beam 113 corresponding to the avoidance groove 121, a part of the sill beam 113 close to the front floor panel 12 is removed by machining to form a mounting groove 1131. The dimension of the mounting groove 1131 in the length direction X is adapted to the dimension of the avoidance groove 121 of the front floor panel 12 in the length direction X, so as to ensure that the first overlapping portion 123 and the second overlapping portion 111 can overlap with each other. A reinforcing member 114 is provided at the notch formed by cutting the sill beam 113. The reinforcing member 114 can further improve the side collision prevention performance of the vehicle body assembly 10. The first overlapping sub-portion 1111 on the sill beam 113 is smoothly connected to the second overlapping sub-portion 1112 on the reinforcing member 114 to further ensure that the first overlapping portion 123 and the second overlapping portion 111 are closely attached.

[0047] By the above method, since the cooperation groove 112 needs to be provided in the sill assembly 11, in this embodiment, the sill beam 113 and the reinforcing member 114 which are designed as a split assembly structure can simplify the preparation process of the sill assembly 11 and reduce the preparation cost of the sill assembly 11. This is because the dimension of the reinforcing member 114 in the length direction X is smaller than the dimension of the sill beam 113 in the length direction X. By designing the cooperation groove 112 separately for the reinforcing member 114, the preparation process is simple and the cost is low. If the cooperation groove 112 is directly designed on the sill beam 113, since the structure of the sill beam 113 is different from the conventional structure at this time and needs to be manufactured separately, this will lead to a complex preparation process and an increase in the cost of the sill beam 113.

[0048] Optionally, the reinforcing member 114 can specifically be in the form of a casting, etc., which is beneficial to enhancing the structural strength of the reinforcing member 114, and further improving the side collision prevention performance of the vehicle body assembly 10. And, the reinforcing member 114 can be welded and fixed to the cut of the sill beam 113 by friction stir welding, which is not limited here.

[0049] In one embodiment, the reinforcing member 114 includes a first structural portion 1141, a second structural portion 1142, a third structural portion 1143 and a reinforcing rib 1144. The first structural portion 1141 and the second structural portion 1142 are spaced apart along the height direction Z of the vehicle body assembly 10, and one side of the first structural portion 1141 and the second structural portion 1142 close to the front floor panel 12 is connected by the third structural portion 1143. The reinforcing rib 1144 is located on the side of the third structural portion 1143 away from the front floor panel 12, and the reinforcing rib 1144 is respectively connected to the first structural portion 1141, the second structural portion 1142 and the third structural portion 1143. A second overlapping sub-portion 1112 is connected to the side of the third structural portion 1143 away from the reinforcing rib 1144.

[0050] In the above manner, the reinforcement member 114 of this embodiment is provided with reinforcement ribs 1144, and the reinforcement ribs 1144 are respectively connected to the first structural portion 1141, the second structural portion 1142 and the third structural portion 1143, so that the overall structural strength of the reinforcement member 114 can be greatly improved, thereby further improving the side collision protection performance of the vehicle body assembly 10.

[0051] Please continue reading Figure 1 and Figure 2 In one embodiment, the seat mounting assembly 13 includes a seat mounting front beam 131 and a seat mounting rear beam 132. The seat mounting front beam 131 and the seat mounting rear beam 132 are spaced apart along the length direction X of the vehicle body assembly 10, and the seat mounting front beam 131 is closer to the front wall cross beam assembly 15 than the seat mounting rear beam 132. At least the end of the seat mounting rear beam 132 close to the door sill assembly 11 is embedded in the avoidance groove 121.

[0052] Specifically, in the width direction Y, the edges of the front floor panel 12 close to the threshold assemblies 11 on both sides are provided with avoidance grooves 121. Both ends of the seat mounting rear beam 132 are embedded in the avoidance grooves 121 on both sides of the front floor panel 12, and the seat mounting rear beam 132 is respectively connected to the threshold assemblies 11 on both sides. Both ends of the seat mounting front beam 131 are also respectively connected to the threshold assemblies 11 on both sides. The seat mounting assembly 13 also includes a central channel 133. The central channel 133 extends along the length direction X, and the central channel 133 is respectively connected to the seat mounting front beam 131 and the seat mounting rear beam 132, and the seat mounting front beam 131, the seat mounting rear beam 132 and the central channel 133 form a structure similar to the Chinese character "土".

[0053] Furthermore, for the example in which the vehicle body assembly 10 further includes a battery pack 14, the battery pack 14 is located on a side of the front floor panel 12 away from the seat mounting assembly 13. Figure 3 As shown, a reinforcing beam 141 is provided in the battery pack 14 , and in the height direction Z of the vehicle body assembly 10 , the reinforcing beam 141 is arranged opposite to the seat installation rear beam 132 .

[0054] In the above manner, in this embodiment, a reinforcing beam 141 is provided at a position corresponding to the seat mounting rear beam 132 in the battery pack 14 , and the reinforcing beam 141 extends along the width direction Y of the vehicle body assembly 10 . The reinforcing beam 141 can further enhance the side collision resistance of the vehicle body assembly 10 .

[0055] It should be noted that the avoidance groove 121 is arranged close to the B-pillar structure of the vehicle. The dimension of the avoidance groove 121 in the length direction X can cover the entire B-pillar structure, so as to ensure to the greatest extent that the part of the seat mounting assembly 13 located in the avoidance groove 121 can be designed with a larger cross-sectional height, directly improving the side anti-collision stiffness of the vehicle body assembly 10, enhancing the side anti-collision performance of the vehicle body assembly 10 through the seat mounting assembly 13, being beneficial to reducing the lateral deformation of the occupant compartment, and protecting the safety of the driver and passengers to the greatest extent.

[0056] In summary, the present application provides a vehicle body assembly and a vehicle. In this vehicle body assembly, an avoidance groove is arranged at the edge of the front floor panel close to the sill assembly, and at least part of the seat mounting assembly is embedded in the avoidance groove. By arranging the avoidance groove, the present application allows the part of the seat mounting assembly located in the avoidance groove to be designed with a larger cross-sectional height, so as to enhance the side anti-collision performance of the vehicle body assembly through the seat mounting assembly.
