[0003] The vehicle body, as the space that carries passengers, is a crucial part of the vehicle, and its reliability is paramount. The structural strength of the vehicle body has a significant impact on improving the vehicle's crash performance. How to improve the structural strength of the vehicle body has always been a key focus for those skilled in the art. Utility Model Content

[0009] According to some embodiments of this application, the vehicle body further includes a sealing structure sandwiched between the connecting structure and the first cover plate. By sandwiching the sealing structure between the connecting structure and the first cover plate, the sealing structure can seal the gap between the connecting structure and the first cover plate, and the sealing structure is located between the connecting structure and the first cover plate in a third direction, so that the sealing structure can make full use of the gap in the third direction.

[0010] According to some embodiments of the present application, the A-pillar further includes a connecting plate connected to the first cover plate and the second cover plate. The connecting plate is located in a cavity, and the sill beam is connected to the connecting plate by a third bolt assembly. By placing the connecting plate in the cavity, it is advantageous that the connecting plate does not need to occupy additional space outside the A-pillar, which helps to improve the compactness of the overall body structure.

[0011] According to some embodiments of the present application, the bolt head of the bolt in the third bolt assembly is located on the side of the sill beam away from the A-pillar, so that the bolt in the third bolt assembly is inserted from the side of the sill beam away from the A-pillar, and the bolt in the third bolt assembly is installed from outside the cabin to inside the cabin, which helps to shorten the installation and disassembly time.

[0015] According to some embodiments of the present application, the sill beam is connected to the connecting structure via a second bolt assembly. The connection between the sill beam and the connecting structure via the second bolt assembly facilitates the connection and disassembly of the connecting structure and the sill beam.

[0016] According to some embodiments of the present application, the bolt head of the bolt in the second bolt assembly is located on the side of the sill beam away from the connecting structure, so that the bolt in the second bolt assembly is inserted from the side of the sill beam away from the connecting structure, and the bolt in the second bolt assembly is installed from outside the cabin to inside the cabin, which helps to shorten the installation and disassembly time.

[0017] According to some embodiments of this application, the torsion box and the front bulkhead are integrally formed, which allows the torsion box and the front bulkhead to be manufactured as a whole and synchronously. This not only makes the processing and manufacturing of the torsion box and the front bulkhead convenient, but also gives the overall structure of the torsion box and the front bulkhead good strength.

[0018] Secondly, this application provides a vehicle including a chassis and a body as provided in any of the above technical solutions, the body being connected to the chassis.

The sill beam is connected to the lower side of the A-pillar in the vertical direction and to the lower side of the connecting structure in the vertical direction, with the vertical direction perpendicular to the first direction. In the above structure, because the sill beam is connected to the lower side of the A-pillar in the vertical direction and the connecting structure is also located on the lower side of the vertical direction, and the connecting structure is connected to the A-pillar, the front bulkhead, A-pillar, and sill beam can be firmly connected to each other through the torsion box, giving the vehicle body good structural strength and improving the vehicle's collision performance.

[0035] As vehicle technology continues to develop, people have increasingly higher demands for vehicle performance. In particular, with the widespread application of electric vehicles powered by batteries, people are paying more and more attention to vehicle crash performance.

[0036] The vehicle body, as the space carrying passengers, has a significant impact on the vehicle's collision performance due to its structural strength. To achieve good structural strength and improve collision performance, some embodiments of this application provide a vehicle body including a front bulkhead, a torsion box, an A-pillar, and a sill beam. The torsion box is connected to the front bulkhead and has a connecting structure protruding outward along a first direction. The A-pillar is located on the outer side of the front bulkhead in the first direction and is connected to the connecting structure. The sill beam connects to the lower vertical side of the A-pillar and the lower vertical side of the connecting structure, with the vertical direction perpendicular to the first direction. In this structure, because the sill beam connects to the lower vertical side of the A-pillar and the lower vertical side of the connecting structure, and the connecting structure is connected to the A-pillar, the torsion box, A-pillar, and sill beam are firmly connected to each other, giving the vehicle body good structural strength and improving collision performance.

Vehicles can be gasoline-powered vehicles, natural gas-powered vehicles, or new energy vehicles; new energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc.

[0038] The technical solutions for the vehicle body and vehicle provided in the specific embodiments of this application are further described below.

[0039] Some embodiments of this application provide a vehicle body, see reference Figure 1 The vehicle body includes a front bulkhead 1, a torsion box 2, an A-pillar 3, and a sill beam 4. The torsion box 2 is connected to the front bulkhead 1, and a connecting structure 21 protrudes outward along a first direction X. The A-pillar 3 is located on the outside of the front bulkhead 1 in the first direction X and is connected to the connecting structure 21. The sill beam 4 is connected to the lower side of the A-pillar 3 in the vertical direction Y and to the lower side of the connecting structure 21 in the vertical direction Y, where the vertical direction Y is perpendicular to the first direction X. In this structure, because the sill beam 4 is connected to the lower side of the A-pillar 3 in the vertical direction Y and the connecting structure 21 is also connected to the A-pillar 3, the front bulkhead 1, A-pillar 3, and sill beam 4 can be firmly connected to each other through the torsion box 2, giving the vehicle body good structural strength and improving its collision performance.

[0040] The front partition 1 can refer to the partition located between the engine compartment and the passenger compartment in the vehicle body, which can isolate and protect the interior of the passenger compartment.

[0041] Torque box 2 can be a structure used to distribute the torque on the body structure to other parts of the body. It is connected to the front bumper 1, A-pillar 3 and sill beam 4, so that the front bumper 1, A-pillar 3 and sill beam 4 can be connected relatively firmly. The torque on any one of the front bumper 1, A-pillar 3 and sill beam 4 can be transmitted and distributed to the other two, so that the body is not easily damaged.

[0042] The connecting structure 21 can refer to a structure protruding outward along the first direction X on the torque box 2, used for connecting with the sill beam 4 and the A-pillar 3. By protruding outward along the first direction X, the connecting structure 21 extends from both sides of the main body of the torque box 2 in the first direction X, allowing the sill beam 4 and A-pillar 3 on both sides of the first direction X to connect with the torque box 2 from the outside. Here, the first direction X can refer to the left-right direction of the vehicle.

[0043] The A-pillar 3 can be a connecting pillar at the front of the vehicle body, connecting the roof and the front compartment, and it is located on the outer side of the front bulkhead 1 in the first direction X. The A-pillar 3 being located on the outer side of the front bulkhead 1 in the first direction X can mean that the front bulkhead 1 has A-pillars 3 on both sides in the first direction X, so that the two A-pillars 3 can provide firm support for the roof.

[0044] The connection of column A3 to connection structure 21 can mean that column A3 is connected to connection structure 21 by welding or bonding, or it can mean that column A3 is connected to connection structure 21 by connecting bolts, connecting pins or other connecting parts.

[0045] The door sill beam 4 can refer to a beam-like component located below the door of the vehicle body. The door sill beam 4 is connected to the A-pillar 3 on the lower side in the vertical Y direction.

[0046] The threshold beam 4 is connected to the lower side of column A 3 in the vertical direction Y and the lower side of connecting structure 21 in the vertical direction Y. This can mean that the threshold beam 4 is located on the lower side of column A 3 in the vertical direction Y and the lower side of connecting structure 21 in the vertical direction Y, and is connected to column A 3 and connecting structure 21 from the lower side.

[0047] In the above structure, since the sill beam 4 is connected to the lower side of the A-pillar 3 in the vertical direction Y and the connecting structure 21 is also connected to the lower side of the vertical direction Y, and the connecting structure 21 is connected to the A-pillar 3, the torsion box 2, the A-pillar 3 and the sill beam 4 can be firmly connected to each other, so that the vehicle body has good structural strength and is conducive to improving the collision performance of the vehicle.

[0048] In some embodiments, at least a portion of the A-pillar 3 is arranged with the connecting structure 21 along a third direction Z. The connecting structure 21 is connected to the portion of the A-pillar 3 arranged with the connecting structure 21 along the third direction Z. The third direction Z is perpendicular to the first direction X and the vertical direction Y.

[0049] By setting the third direction Z to be perpendicular to the first direction X and the vertical direction Y, the third direction Z becomes the forward and backward direction of the vehicle.

[0050] The arrangement of at least a portion of the A-pillar 3 and the connecting structure 21 along the third direction Z can mean that a portion of the A-pillar 3 and the connecting structure 21 are arranged along the third direction Z, i.e., the projection of a portion of the A-pillar 3 onto the connecting structure 21 in the third direction Z; or it can mean that the entire A-pillar 3 and the connecting structure 21 are arranged along the third direction Z, i.e., the projection of the entire A-pillar 3 onto the connecting structure 21 in the third direction Z.

[0051] By arranging at least a portion of column A 3 and connecting structure 21 along the third direction Z, at least a portion of column A 3 and connecting structure 21 are arranged to overlap along the third direction Z, so that at least a portion of column A 3 can be connected to connecting structure 21.

[0052] By connecting the connecting structure 21 to the portion of the A-pillar 3 arranged in the third direction Z, the adhesive structure, welded structure, or connector used to connect the A-pillar 3 and the connecting structure 21 can be connected by arranging them along the third direction Z.

[0053] In some embodiments, the A-pillar 3 includes a first cover plate 31 and a second cover plate 32, which are fastened together to form a cavity 33; the first cover plate 31 is located inside the second cover plate 32 in the first direction X, and at least a portion of the first cover plate 31 is arranged and connected to the connecting structure 21 in the third direction Z.

[0054] The first cover plate 31 and the second cover plate 32 are different structures in the A-pillar 3. Both the first cover plate 31 and the second cover plate 32 can be hollow structures with an opening on one side. The first cover plate 31 and the second cover plate 32 can be interlocked by the opening side of the first cover plate 31 being interlocked with the opening side of the second cover plate 32 to form an A-pillar 3 with a cavity 33. Because a cavity 33 is formed in the A-pillar 3, the material used in the A-pillar 3 is reduced, which is beneficial to the lightweight design of the vehicle body.

[0055] For example, the first cover plate 31 and the second cover plate 32 can be connected to each other by welding, so that the materials of the first cover plate 31 and the second cover plate 32 can be fused together, which is beneficial to improving the connection strength of the first cover plate 31 and the second cover plate 32.

[0056] The first cover plate 31 is located inside the second cover plate 32 in the first direction X, so that the first cover is closer to the torsion box 2 than the second cover, and at least a portion of the first cover plate 31 can be more easily arranged and connected to the connecting structure 21 in the third direction Z.

[0057] In some embodiments, the vehicle body further includes a sealing structure 5, which is sandwiched between the connecting structure 21 and the first cover plate 31.

[0058] The sealing structure 5 can be a structure used to seal the gap between the connecting structure 21 and the first cover plate 31. By sandwiching the sealing structure 5 between the connecting structure 21 and the first cover plate 31, the sealing structure 5 can seal the gap between the connecting structure 21 and the first cover plate 31. The sealing structure 5 is located between the connecting structure 21 and the first cover plate 31 in the third direction Z, so that the sealing structure 5 can make full use of the gap in the third direction Z.

[0059] For example, the sealing structure 5 may be formed by curing sealant that fills the gap between the connecting structure 21 and the first cover plate 31, or it may be formed by a sealing elastic gasket sandwiched between the connecting structure 21 and the first cover plate 31.

[0060] In some embodiments, reference Figure 2 The A-pillar 3 also includes a connecting plate (not shown in the figure) connected to the first cover plate 31 and the second cover plate 32. The connecting plate is located in the cavity 33, and the sill beam 4 is connected to the connecting plate by the third bolt assembly 6.

[0061] The connecting plate can be a structure in column A3 used to connect with the sill beam 4, which is used to improve the connection strength between the sill beam 4 and column A3.

[0062] The connecting plate can be connected to both the first cover plate 31 and the second cover plate 32, enabling it to stably transmit forces between the A-pillar 3 and the sill beam 4. For example, the connecting plate can be welded to both the first cover plate 31 and the second cover plate 32, allowing the material of the connecting plate to be fused together with the materials of both the first cover plate 31 and the second cover plate 32, thereby improving the connection strength between the connecting plate and both the first and second cover plates 31 and 32.

[0063] By placing the connecting plate in the cavity 33, it is possible to avoid the connecting plate occupying additional space beyond the A-pillar 3, which helps to improve the compactness of the overall body structure.

[0064] The third bolt assembly 6 can be a bolt assembly used to connect the sill beam 4 and the connecting plate. The sill beam 4 is connected to the connecting plate via the third bolt assembly 6, making it easy to connect and disassemble the sill beam 4 and the A-pillar 3.

[0065] In some embodiments, reference Figure 3 In the third bolt assembly 6, the bolt head of the bolt is located on the side of the threshold beam 4 away from the A-pillar 3.

[0066] The bolt head of the bolt in the third bolt assembly 6 is located on the side of the sill beam 4 away from the A-pillar 3. This means that the bolt in the third bolt assembly 6 is inserted from the side of the sill beam 4 away from the A-pillar 3, so that the bolt in the third bolt assembly 6 is installed from outside the cabin to inside the cabin, which helps to shorten the installation and disassembly time.

[0067] In some embodiments, the connection structure 21 is connected to the A-pillar 3 via a first bolt assembly 7.

[0068] The first bolt assembly 7 can be a bolt assembly used to connect the connecting structure 21 and the A-pillar 3. The A-pillar 3 is connected to the connecting structure 21 through the first bolt assembly 7, which makes it convenient to connect and disassemble the connecting structure 21 and the A-pillar 3.

[0069] In some embodiments, at least two first bolt assemblies 7 are provided, and the at least two first bolt assemblies 7 are spaced apart along a third direction Z, which is perpendicular to the first direction X and the vertical direction Y.

[0070] By providing at least two first bolt assemblies 7, and having at least two first bolt assemblies 7 equally spaced along the third direction Z, the first bolt assemblies 7 enable the A-pillar 3 to be securely and stably connected to the connecting structure 21.

[0071] For example, two first bolt assemblies 7 may be equally spaced along the third direction Z, or three or more first bolt assemblies 7 may be equally spaced along the third direction Z, so as to securely and stably connect the A-pillar 3 to the connecting structure 21.

[0072] In some embodiments, the bolt head of the bolt in the first bolt assembly 7 is located on the side of the connection structure 21 away from the A-pillar 3.

[0073] The bolt head of the bolt in the first bolt assembly 7 is located on the side of the connecting structure 21 away from the A-pillar 3. This means that the bolt in the first bolt assembly 7 is inserted from the side of the connecting structure 21 away from the A-pillar 3, so that the bolt in the first bolt assembly 7 is installed from outside the cabin to inside the cabin, which helps to shorten the installation and disassembly time.

[0074] In some embodiments, reference Figure 3 The threshold beam 4 is connected to the connecting structure 21 by the second bolt assembly 8.

[0075] The second bolt assembly 8 can be a bolt assembly used to connect the sill beam 4 and the connecting structure 21. The sill beam 4 is connected to the connecting structure 21 via the second bolt assembly 8, making it convenient to connect and disassemble the connecting structure 21 and the sill beam 4.

[0076] In some embodiments, the bolt heads of the connecting bolts in the second bolt assembly 8 are located on the side of the sill beam 4 away from the connecting structure 21.

[0077] The bolt head of the bolt in the second bolt assembly 8 is located on the side of the sill beam 4 away from the connecting structure 21. This means that the bolt in the second bolt assembly 8 is inserted from the side of the sill beam 4 away from the connecting structure 21, so that the bolt in the second bolt assembly 8 is installed from outside the cabin to inside the cabin, which helps to shorten the installation and disassembly time.

[0078] In some embodiments, the torque box 2 and the front enclosure are integrally formed.

[0079] The torque box 2 and the front baffle are integrally molded structures, which means that the torque box 2 and the front baffle are made by integral molding processing methods such as casting. This allows the torque box 2 and the front baffle to be manufactured as a whole and synchronously. This not only makes the processing and manufacturing of the torque box 2 and the front baffle convenient, but also gives the overall structure of the torque box 2 and the front baffle good strength.

[0080] Some embodiments of this application also provide a vehicle, which includes a chassis and a body as described in the above technical solutions, the body being connected to the chassis.

[0081] Because the vehicle incorporates the body provided by the aforementioned technical solution, the body has good structural strength, resulting in good collision performance.

[0082] In some embodiments, the chassis also includes an energy compartment housing a battery device for providing electrical power.

[0083] The energy compartment can refer to the part of the chassis that houses the battery pack. The battery pack is located within the walls of the energy compartment, which provides protection for it.

[0084] Some embodiments of this application provide a vehicle body, such as Figure 1 As shown, the vehicle body includes a front bulkhead 1, a torque box 2, an A-pillar 3, a sealing structure 5, and a door sill beam 4. The torque box 2 is integrally formed on the front bulkhead 1. The torque box 2 has a connecting structure 21 protruding outward along the first direction X. The front bulkhead 1 has A-pillars 3 on both sides of the first direction X. At least a portion of the A-pillars 3 is arranged and connected to the connecting structure 21 along the third direction Z. The door sill beam 4 is connected to the lower side of the A-pillars 3 in the vertical direction Y and the lower side of the connecting structure 21 in the vertical direction Y. The sealing structure 5 is sandwiched between the connecting structure 21 and the A-pillars 3.

[0085] In the above structure, since the sill beam is connected to the lower side of the A-pillar in the vertical direction and the connecting structure is also connected to the lower side of the vertical direction, and the connecting structure is connected to the A-pillar, the front bumper, A-pillar and sill beam can be firmly connected to each other through the torsion box, so that the vehicle body has good structural strength and is conducive to improving the vehicle's collision performance.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
