[0047] According to the vehicle body 1 of the embodiment of the present invention, the cabin assembly 100 is provided with a first mounting portion 110, the front floor assembly 200 is connected to the rear side of the cabin assembly 100, the front floor assembly 200 includes a front floor 210 and a seat cross beam 220, the seat cross beam 220 is arranged on the front floor 210 and is spaced apart in the front-to-rear direction, the seat cross beam 220 is provided with a second mounting portion 221, that is, the seat cross beam 220 can be multiple, the seat cross beam 220 extends in the left-right direction and the multiple seat cross beams 220 are spaced apart in the front-to-rear direction, so that each seat cross beam 220 is provided with a second mounting portion 221, and there are multiple second mounting portions 221, the first type of battery pack 500 or the second type of battery pack 600 can be connected to multiple seat cross beams 220, thereby improving the connection stability between the seat cross beam 220 and the first type of battery pack 500 or the second type of battery pack 600.

[0048] In addition, the threshold beam 300 is connected to the rear side of the cabin assembly 100 and is also connected to the left and right sides of the front floor 210 and the seat cross beam 220, the threshold beam 300 is provided with a third mounting portion 310, the rear floor assembly 400 is connected to the front floor 210 and the rear side of the threshold beam 300, the front side of the rear floor assembly 400 is provided with a fourth mounting portion 410 and the rear side is provided with a fifth mounting portion 420.

[0049] Among them, the first mounting part 110, the second mounting part 221, the third mounting part 310, the fourth mounting part 410 and the fifth mounting part 420 constitute a first mounting group, and the first mounting group is used to install the first type of battery pack 500; the second mounting part 221 and the fourth mounting part 410 constitute a second mounting group, and the second mounting group is used to install the second type of battery pack 600, which is different from the first type of battery pack 500.

[0050] In this way, the cabin assembly 100, the front floor assembly 200, the door sill beam 300 and the rear floor assembly 400 can be connected into a whole, and the cabin assembly 100 can fix the front part of the first type of battery pack 500, the front floor assembly 200 can fix the middle part of the first type of battery pack 500 or the front and middle part of the second type of battery pack 600, the door sill beam 300 can fix the side of the first type of battery pack 500, and the rear floor assembly 400 can fix the rear part of the first type of battery pack 500 or the rear part of the second type of battery pack 600, so that the vehicle body 1 can be used to connect and fix multiple parts of the first type of battery pack 500 or multiple parts of the second type of battery pack 600, so that the first type of battery pack 500 or the second type of battery pack 600 can be stably connected to the bottom of the vehicle body 1.

[0051] Furthermore, with such an arrangement, the first type of battery pack 500 can be installed in the first installation group, and the first type of battery pack 500 can cover the entire front floor assembly 200, and the first type of battery pack 500 can be circumferentially connected to the cabin assembly 100, the door sill beam 300 and the rear floor assembly 400, respectively, that is, the volume of the first type of battery pack 500 can be set larger, so that the battery pack for the EV model can be fixed using the vehicle body 1.

[0053] Therefore, the vehicle body 1 of the embodiment of the present invention can be used to install a battery pack for an EV model, or to install a battery pack for a PHEV model. The vehicle body 1 has higher versatility, and there is no need to modify the structure of the vehicle body 1 when installing different types of battery packs, so that the structure of the vehicle body 1 is simpler, and there is no need to develop components separately for different types of battery packs, so the development cost is lower.

[0054] In this way, the vehicle body 1 according to the embodiment of the present invention can be used to install different types of battery packs, and has the advantages of simple structure, high versatility and low development cost.

[0055] In some specific embodiments of the present invention, Figure 7-Figure 9 As shown, the seat cross beam 220 includes a cross beam body 230 and a sleeve 240 .

[0056] A groove 231 opening upward is formed in the middle of the width direction of the beam body 230 . The sleeve 240 is disposed in the groove 231 and connected to the bottom of the groove 231 . The sleeve 240 constitutes the second mounting portion 221 .

[0057] Specifically, the first type of battery pack 500 or the second type of battery pack 600 can be screwed together via a fastener and a sleeve 240. By providing the sleeve 240, it is helpful to increase the connection area between the fastener and the seat cross beam 220, so that the connection between the first type of battery pack 500 or the second type of battery pack 600 and the seat cross beam 220 is more reliable.

[0058] Furthermore, by providing the crossbeam body 230 with a groove 231, the upper surface of the crossbeam body 230 is non-planar, which is beneficial to improving the structural strength of the crossbeam body 230, and the crossbeam body 230 is less likely to deform, thereby making the support capacity of the seat crossbeam 220 stronger. Moreover, the sleeve 240 can be arranged in the groove 231, so that the sleeve 240 will not exceed the upper surface of the crossbeam body 230, and the seat crossbeam 220 will not occupy too much space, thereby avoiding position interference between the sleeve 240 and other components.

[0059] In addition, by providing the groove 231 and the sleeve 240 being provided in the groove 231, the thickness of the beam body 230 at the groove 231 can be thinner, so that the distance between the sleeve 240 and the battery pack can be closer, thereby facilitating the fastener to pass through the battery pack and the beam body 230 in turn and then connect with the sleeve 240, so that the connection between the battery pack and the seat beam 220 is more stable and reliable.

[0060] Among them, at least one of the first mounting part 110, the third mounting part 310, the fourth mounting part 410 and the fifth mounting part 420 is a nut plate, that is, the first mounting part 110, the third mounting part 310, the fourth mounting part 410 and the fifth mounting part 420 can be provided with a plurality of bolt holes, so that the first type of battery pack 500 can be connected to the first mounting part 110, the third mounting part 310, the fourth mounting part 410 and the fifth mounting part 420 by bolts, and the second type of battery pack 600 can be connected to the second mounting part 221 and the fourth mounting part 410 by bolts, which is conducive to simplifying the structure of the first mounting part 110, the third mounting part 310, the fourth mounting part 410 and the fifth mounting part 420, and making the connection between the battery pack and the first mounting part 110, the third mounting part 310, the fourth mounting part 410 and the fifth mounting part 420 more stable and reliable.

[0061] In some specific embodiments of the present invention, Figure 8 and Fig. 9 As shown, the beam body 230 includes a first connecting bracket 232 and a second connecting bracket 233 .

[0062] The first connecting bracket 232 is connected between the front side wall of the groove 231 and the sleeve 240 , and the second connecting bracket 233 is connected between the rear side wall of the groove 231 and the sleeve 240 .

[0063] It can be understood that the outer diameter of the sleeve 240 can be smaller than the width of the groove 231, so that the allowable error of the assembly of the sleeve 240 and the groove 231 can be larger, which is convenient for setting the sleeve 240 in the groove 231, and, by setting the first connecting bracket 232 and the second connecting bracket 233, the connection area between the first connecting bracket 232 and the front side wall of the groove 231 can be larger, and the connection area between the first connecting bracket 232 and the sleeve 240 can also be larger, the connection strength between the first connecting bracket 232 and the front side wall of the groove 231 and the sleeve 240 can be higher, thereby increasing the connection strength between the sleeve 240 and the front side wall of the groove 231, and the connection area between the second connecting bracket 233 and the rear side wall of the groove 231 can be larger, and the connection area between the second connecting bracket 233 and the sleeve 240 can also be larger, the connection strength between the second connecting bracket 233 and the rear side wall of the groove 231 and the sleeve 240 can be higher, thereby increasing the connection strength between the sleeve 240 and the rear side wall of the groove 231.

[0064] For example, the sleeve 240 can be constructed as a hollow cylinder, and the side of the first connecting bracket 232 facing the sleeve 240 can be constructed as an arc shape that matches the outer circumferential surface of the sleeve 240 to increase the connection area between the first connecting bracket 232 and the sleeve 240, so that the connection strength between the first connecting bracket 232 and the sleeve 240 is higher, and the side of the second connecting bracket 233 facing the sleeve 240 can be constructed as an arc shape that matches the outer circumferential surface of the sleeve 240 to increase the connection area between the second connecting bracket 233 and the sleeve 240, so that the connection strength between the second connecting bracket 233 and the sleeve 240 is higher.

[0065] In some specific embodiments of the present invention, Figure 7-Figure 9 As shown, the beam body 230 includes a front beam portion 234 , a rear beam portion 236 and a connecting plate portion 238 .

[0066] A front cavity 235 is formed in the front beam portion 234 , a rear cavity 237 is formed in the rear beam portion 236 , and the connecting plate portion 238 is connected between the front beam portion 234 and the rear beam portion 236 and forms a groove 231 together with the front beam portion 234 and the rear beam portion 236 .

[0067] In this way, the dimension of the beam body 230 in the height direction can be larger, that is, the thickness of the beam body 230 can be thicker, which greatly improves the ability of the beam body 230 to resist bending in the height direction, which is beneficial to improving the rigidity of the vehicle in the front floor 210 area.

[0068] Among them, the front beam portion 234 and the rear beam portion 236 can be symmetrically arranged about the center of the groove 231, that is, the groove 231 can be arranged at the center of the width direction of the beam body 230, so that the structural strength of the front side of the groove 231 and the rear side of the groove 231 are similar, avoiding excessive difference in the structural strength of the front beam portion 234 or the rear beam portion 236, thereby ensuring that the overall structural strength of the beam body 230 can be higher and the supporting stability of the seat beam 220 is better.

[0069] Moreover, by providing the front cavity 235 and the rear cavity 237, the processing materials of the front beam portion 234 and the rear beam portion 236 can be reduced to reduce the processing cost of the seat cross beam 220. At the same time, the weight of the cross beam body 230 can be greatly reduced, thereby reducing the weight and cost of the vehicle body 1.

[0070] In some specific embodiments of the present invention, Figure 7 As shown, the seat cross beam 220 further includes a seat support 222 and a joint structure 223 .

[0071] The seat supports 222 are disposed on the top of the cross beam body 230 and are spaced apart in the left-right direction. The joint structure 223 is disposed at the end of the cross beam body 230 , and the joint structure 223 is connected to the door sill beam 300 .

[0072] That is, there can be multiple seat supports 222, and multiple seat supports 222 are arranged on the top of the beam body 230 and are spaced apart in the left and right directions of the vehicle, so that part of the multiple seat supports 222 can be used to fix one seat, and another part of the multiple seat supports 222 can be used to fix another seat.

[0073] In addition, by setting the joint structure 223, the joint structure 223 can be welded or fixedly connected to the crossbeam body 230 and the threshold beam 300 respectively, and the joint structure 223 can be easily constructed into an irregular shape, so that the joint structure 223 can be connected to the upper surface and the inner side of the threshold beam 300, thereby increasing the contact area between the seat crossbeam 220 and the threshold beam 300, and the connection area between the joint structure 223 and the threshold beam 300 can be larger, and the connection strength between the seat crossbeam 220 and the threshold beam 300 is higher, so that the connection between the seat crossbeam 220 and the threshold beam 300 is more stable and reliable.

[0074] In some specific embodiments of the present invention, Figure 4 and Figure 5As shown, a through hole 211 is formed on the front panel, and the second mounting portion 221 corresponds to the through hole 211 in the up and down directions. It can be understood that the first type of battery pack 500 or the second type of battery pack 600 can be connected to the second mounting portion 221 through a fastener, and the fastener will be exposed from the upper side of the second mounting portion 221 after passing through the second mounting portion 221. By setting the through hole 211, not only is it convenient to connect the fastener and the second mounting portion 221, but also the assembly is more convenient and the position interference between the fastener and the front floor 210 can be avoided.

[0075] For example, a sealing surface 212 may be provided at the edge of the through hole 211, that is, the sealing surface 212 may surround the through hole 211 along the circumference of the through hole 211, and the first type of battery pack 500 or the second type of battery pack 600 may be connected to the lower side of the front floor 210, and the front panel may cooperate with the first type of battery pack 500 or the second type of battery pack 600 through the sealing surface 212 to form a sealing structure, so that the upper cover of the first type of battery pack 500 or the upper cover of the second type of battery pack 600 can replace the floor of the vehicle, which is beneficial to compressing the size of the vehicle body 1 in the height direction, thereby increasing the height space in the passenger compartment and reducing the overall weight of the vehicle.

[0076] In some specific embodiments of the present invention, Figure 1 , Figure 5 and Figure 6 As shown, the cabin assembly 100 includes a front panel 120 and a center channel member 130 .

[0077] The front end of the middle channel member 130 is connected to the front panel 120 , and the rear end of the middle channel member 130 is located on the front floor 210 and connected to the seat cross beam 220 located at the frontmost side.

[0078] That is to say, compared with the middle channel member in the prior art, the middle channel member 130 in the embodiment of the present invention can be shorter in the front-to-back direction. The middle channel member 130 only extends from the front panel 120 to the front seat cross beam 220 at the frontmost side. The exhaust system, fuel, brake and water cooling pipelines and high-voltage wiring harness can pass through the middle channel member 130, and then extend from the sides of the second type of battery pack 600 to the rear of the vehicle respectively. In this way, the middle channel member 130 does not need to pass through the seat cross beam 220, and the seat cross beam 220 does not need to avoid the middle channel member 130, that is, the seat cross beam 220 can be straightened, so that the lateral force transmission channel of the vehicle body 1 is greatly improved.

[0079] In some specific embodiments of the present invention, Figure 4 and Figure 6 As shown, the nacelle assembly 100 includes a central channel reinforcement plate 140 and a torsion box 150 .

[0080] The middle channel reinforcement plate 140 is disposed at the bottom of the middle channel, and the torque box 150 is respectively connected to the left and right sides of the middle channel reinforcement plate 140 .

[0081] Among them, the middle channel reinforcement plate 140 can be fitted with the lower surface of the middle channel member 130, so that the middle channel member 130 can be supported by the middle channel reinforcement plate 140 to improve the reliability of the fixation of the middle channel member 130, and the middle channel reinforcement plate 140 will not occupy too much space on the lower side of the middle channel member 130.
