Description

Technical Field

[0041] In the description of this invention, "a plurality of" means two or more, and "several" means one or more.

[0042] The vehicle body 1 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0043] like Figures 1-12 As shown, the vehicle body 1 according to the present invention includes an engine compartment assembly 100, a front floor assembly 200, a door sill beam 300, and a rear floor assembly 400.

[0044] The cabin assembly 100 is provided with a first mounting part 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 crossbeam 220. The seat crossbeam 220 is provided on the front floor 210 and is spaced apart in the front-rear direction. The seat crossbeam 220 is provided with a second mounting part 221. The sill 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 crossbeam 220. The sill beam 300 is provided with a third mounting part 310. The rear floor assembly 400 is connected to the rear side of the front floor 210 and the sill beam 300. The rear floor assembly 400 is provided with a fourth mounting part 410 on the front side and a fifth mounting part 420 on the rear side.

[0045] 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, which is used to install a first type of battery pack 500; the second mounting part 221 and the fourth mounting part 410 constitute a second mounting group, which is used to install a second type of battery pack 600, which is different from the first type of battery pack 500.

[0046] The first type of battery pack 500 can be used for EV (Electric Vehicle) models, and the second type of battery pack 600 can be used for PHEV (Plug-in Hybrid Electric Vehicle) models.

[0047] According to the vehicle body 1 of the present invention, by providing a first mounting portion 110 to the engine compartment assembly 100, a front floor assembly 200 is connected to the rear side of the engine compartment assembly 100. The front floor assembly 200 includes a front floor 210 and a seat crossbeam 220. The seat crossbeams 220 are disposed on the front floor 210 and spaced apart in the front-rear direction. Each seat crossbeam 220 is provided with a second mounting portion 221. That is, there can be multiple seat crossbeams 220. The seat crossbeams 220 extend in the left-right direction and multiple seat crossbeams 220 are spaced apart in the front-rear direction. Thus, each seat crossbeam 220 is provided with a second mounting portion 221. Since there are multiple second mounting portions 221, a first type of battery pack 500 or a second type of battery pack 600 can be connected to multiple seat crossbeams 220, thereby improving the connection stability between the seat crossbeams 220 and the first type of battery pack 500 or the second type of battery pack 600.

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

[0049] 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, which is used to install a first type of battery pack 500; the second mounting part 221 and the fourth mounting part 410 constitute a second mounting group, which is used to install a 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 sill beam 300, and the rear floor assembly 400 can be connected into a whole. The cabin assembly 100 can fix the front of the first type battery pack 500, the front floor assembly 200 can fix the middle of the first type battery pack 500 or the front and middle of the second type battery pack 600, the sill beam 300 can fix the side of the first type battery pack 500, and the rear floor assembly 400 can fix the rear of the first type battery pack 500 or the rear of the second type battery pack 600. Thus, the vehicle body 1 can be used to connect and fix multiple parts of the first type battery pack 500 or multiple parts of the second type battery pack 600, so that the first type battery pack 500 or the second type battery pack 600 can be stably connected to the underside of the vehicle body 1.

[0051] Furthermore, with this configuration, the first type of battery pack 500 can be installed in the first mounting group, and the first type of battery pack 500 can cover the entire front floor assembly 200. Moreover, the circumferential direction of the first type of battery pack 500 can be connected to the engine compartment 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 to be relatively large, so that the battery pack for EV models can be fixed by the vehicle body 1.

[0052] Alternatively, the second type of battery pack 600 can be installed in the second mounting group, that is, the second type of battery pack 600 can be connected to the seat crossbeam 220 and the rear floor assembly 400 respectively, and the side of the second type of battery pack 600 can be not connected to the sill beam 300, so that the side of the second type of battery pack 600 can be spaced apart from the sill beam 300, thereby widening the arrangement space on both sides of the second type of battery pack 600. The exhaust system can be distributed on one side of the second type of battery pack 600, and the fuel, brake and water cooling pipes and high-voltage wiring harness can be arranged on the other side of the second type of battery pack 600, so that the battery pack for PHEV models can be fixed by the vehicle body 1.

[0053] Therefore, the vehicle body 1 of this embodiment can be used to install a battery pack for EV models or a battery pack for PHEV models. The vehicle body 1 has higher versatility. When installing different types of battery packs, there is no need to modify the structure of the vehicle body 1, so that the structure of the vehicle body 1 is simpler and there is no need to develop parts separately for different types of battery packs, resulting in lower development costs.

[0054] Thus, the vehicle body 1 according to 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, such as Figures 7-9 As shown, the seat crossbeam 220 includes a crossbeam body 230 and a sleeve 240.

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

[0057] Specifically, the first type of battery pack 500 or the second type of battery pack 600 can be screwed together by fasteners and sleeves 240. By setting the sleeves 240, it is beneficial to increase the connection area between the fasteners and the seat crossbeam 220, so as to make the connection between the first type of battery pack 500 or the second type of battery pack 600 and the seat crossbeam 220 more reliable.

[0058] Furthermore, by providing a groove 231 to the crossbeam body 230, the upper surface of the crossbeam body 230 is non-planar, which helps to improve the structural strength of the crossbeam body 230 and makes it less prone to deformation, thereby making the support capacity of the seat crossbeam 220 stronger. Moreover, the sleeve 240 can be set 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, thus avoiding positional interference between the sleeve 240 and other components.

[0059] In addition, by setting the groove 231 and the sleeve 240 is set in the groove 231, the thickness of the crossbeam body 230 at the groove 231 can be thinner. This allows the sleeve 240 and the battery pack to be closer, making it easier for the fasteners to pass through the battery pack and the crossbeam body 230 in sequence and then connect with the sleeve 240, so that the connection between the battery pack and the seat crossbeam 220 is more stable and reliable.

[0060] In this configuration, 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 multiple bolt holes. In this way, the first type of battery pack 500 can be bolted to the first mounting part 110, the third mounting part 310, the fourth mounting part 410, and the fifth mounting part 420, and the second type of battery pack 600 can be bolted to the second mounting part 221 and the fourth mounting part 410. This simplifies 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 makes 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, such as Figure 8 and Figure 9 As shown, the crossbeam 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 is understandable that the outer diameter of the sleeve 240 can be smaller than the width of the groove 231. This allows for a larger tolerance in the assembly of the sleeve 240 and the groove 231, making it easier to place the sleeve 240 within the groove 231. Furthermore, by providing the first connecting bracket 232 and the second connecting bracket 233, the connection area between the first connecting bracket 232 and the front wall of the groove 231 can be larger, as can the connection area between the first connecting bracket 232 and the sleeve 240. This results in a higher connection strength between the first connecting bracket 232, the front wall of the groove 231, and the sleeve 240, thereby increasing the connection strength between the sleeve 240 and the front wall of the groove 231. Similarly, the connection area between the second connecting bracket 233 and the rear wall of the groove 231 can be larger, as can the connection area between the second connecting bracket 233 and the sleeve 240. This results in a higher connection strength between the second connecting bracket 233, the rear wall of the groove 231, and the sleeve 240, thereby increasing the connection strength between the sleeve 240 and the rear 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 peripheral surface of the sleeve 240, so as to increase the connection area between the first connecting bracket 232 and the sleeve 240 and make the connection strength between the first connecting bracket 232 and the sleeve 240 higher. The side of the second connecting bracket 233 facing the sleeve 240 can be constructed as an arc shape that matches the outer peripheral surface of the sleeve 240, so as to increase the connection area between the second connecting bracket 233 and the sleeve 240 and make the connection strength between the second connecting bracket 233 and the sleeve 240 higher.

[0065] In some specific embodiments of the present invention, such as Figures 7-9 As shown, the crossbeam 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 a 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 crossbeam body 230 can have a larger dimension in the height direction, that is, the thickness of the crossbeam body 230 can be larger, which greatly improves the ability of the crossbeam body 230 to resist bending in the height direction, and is conducive to improving the rigidity of the vehicle in the front floor 210 area.

[0068] The front beam 234 and the rear beam 236 can be symmetrically arranged about the center of the groove 231, that is, the groove 231 can be set at the center of the width direction of the crossbeam body 230, so that the structural strength of the front side and the rear side of the groove 231 are similar, avoiding excessive differences in the structural strength of the front beam 234 or the rear beam 236, thereby ensuring that the overall structural strength of the crossbeam body 230 is high and the support stability of the seat crossbeam 220 is better.

[0069] Furthermore, by setting the front cavity 235 and the rear cavity 237, the processing material of the front beam 234 and the rear beam 236 can be reduced, thereby reducing the processing cost of the seat crossbeam 220. At the same time, the weight of the crossbeam body 230 can be significantly reduced, thereby reducing the weight and cost of the vehicle body 1.

[0070] In some specific embodiments of the present invention, such as Figure 7 As shown, the seat crossbeam 220 also includes a seat support 222 and a joint structure 223.

[0071] Seat supports 222 are located on the top of the crossbeam body 230 and are spaced apart in the left and right directions. Connector structures 223 are located at the ends of the crossbeam body 230 and are connected to the sill beam 300.

[0072] In other words, there can be multiple seat supports 222. Multiple seat supports 222 are set on the top of the crossbeam body 230 and distributed at intervals in the left and right directions of the vehicle. In this way, a portion of the multiple seat supports 222 can be used to fix one seat, and another portion 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 otherwise fixedly connected to the crossbeam body 230 and the sill beam 300 respectively. The joint structure 223 is easy to be constructed into an irregular shape so that the joint structure 223 can be connected to the upper surface and inner side of the sill beam 300, thereby increasing the contact area between the seat crossbeam 220 and the sill beam 300. The connection area between the joint structure 223 and the sill beam 300 can be larger, and the connection strength between the seat crossbeam 220 and the sill beam 300 is higher, so that the connection between the seat crossbeam 220 and the sill beam 300 is more stable and reliable.

[0074] In some specific embodiments of the present invention, such as Figure 4 and Figure 5As shown, a through hole 211 is formed on the front panel, and the second mounting part 221 corresponds to the through hole 211 in the vertical direction. It can be understood that the first type of battery pack 500 or the second type of battery pack 600 can be connected by fasteners and the second mounting part 221. After the fastener passes through the second mounting part 221, it will be exposed from the upper side of the second mounting part 221. By setting the through hole 211, it is not only convenient to connect the fastener and the second mounting part 221, making assembly more convenient, but also to avoid positional interference between the fastener and the front floor 210.

[0075] For example, a sealing surface 212 can be provided on the edge of the through hole 211, that is, the sealing surface 212 can surround the through hole 211 circumferentially. The first type of battery pack 500 or the second type of battery pack 600 can be connected to the lower side of the front floor 210, and the front panel can 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 sealed structure. In this way, the top cover of the first type of battery pack 500 or the top cover of the second type of battery pack 600 can replace the floor of the vehicle, which is beneficial to compress the dimensions 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, such as Figure 1 , Figure 5 and Figure 6 As shown, the cabin assembly 100 includes a front bulkhead 120 and a central passageway 130.

[0077] The front end of the central channel component 130 is connected to the front bulkhead 120, and the rear end of the central channel component 130 is located on the front floor 210 and connected to the seat crossbeam 220 located at the frontmost side.

[0078] In other words, compared to the central channel component in the prior art, the central channel component 130 in this embodiment of the invention can be shorter in the front-rear direction. The central channel component 130 extends only from the front bulkhead 120 to the frontmost front seat crossbeam 220. The exhaust system, fuel, braking and water cooling pipes, and high-voltage wiring harness can pass through the central channel component 130 and then extend from the side of the second type of battery pack 600 to the rear of the vehicle. In this way, the central channel component 130 does not need to pass through the seat crossbeam 220, and the seat crossbeam 220 does not need to avoid the central channel component 130. That is, the seat crossbeam 220 can be straightened, so as to greatly improve the force transmission channel in the side of the vehicle body 1.

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

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

[0081] The central channel reinforcing plate 140 can be attached to the lower surface of the central channel component 130, thus supporting the central channel component 130 and improving the reliability of its fixation. The central channel reinforcing plate 140 will not occupy too much space on the lower side of the central channel component 130. In addition, by setting the torque box 150 and connecting the central channel reinforcing plate 140 to the torque boxes 150 on the left and right sides respectively, the force transmission between the central channel reinforcing plate 140 and the torque box 150 can be continuous. Furthermore, the longitudinal beam structure on the cabin assembly 100 can be relatively fixed with the sill beam 300 to ensure the continuity of force transmission between the two.
