[0034] As people's living standards continue to improve, the popularity of vehicles is also increasing. The vehicle body, as the component that encloses the passenger compartment, is a crucial component of the vehicle. To enhance passenger comfort, the support plate on the floor of the vehicle body is typically designed to protrude toward the passenger compartment, ensuring comfortable seating for the seats mounted on it. Because the support plate is typically constructed with uniform thickness, when it protrudes toward the passenger compartment, a recessed structure forms on the side of the support plate facing away from the seat.

[0035] In the prior art, the load plate is typically welded to other vehicle body components, such as the floor, forming a single, integral structure that cannot be disassembled. This prevents the recessed structure formed by the load plate from being opened, leaving the space unused and wasting significant space in the vehicle.

[0036] To improve space utilization in a vehicle, the present application provides a vehicle body comprising a beam and a load-bearing plate, the load-bearing plate being detachably connected to the beam. One side of the load-bearing plate is used to support a seat, and a recessed structure is formed on the side of the load-bearing plate facing away from the seat. In this structure, because the load-bearing plate is detachably connected to the beam, the recessed structure formed on the side of the load-bearing plate facing away from the seat can be opened upon removal of the load-bearing plate, allowing electromechanical equipment in the vehicle to be conveniently arranged in the recessed structure, thereby facilitating improved space utilization in the vehicle.

[0037] The vehicle body disclosed in the embodiments of the present application can be used for, but is not limited to, electric vehicles, and can also be used for fuel vehicles and gas vehicles.

[0038] Please refer to Figure 1, which is a schematic structural diagram of a vehicle 1000 provided in some embodiments of the present application. The vehicle 1000 can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery 100 is provided inside the vehicle 1000, and the battery 100 can be provided at the bottom, head or tail of the vehicle 1000. The battery 100 can be used to power the vehicle 1000. For example, the battery 100 can serve as an operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300. The controller 200 is used to control the battery 100 to power the motor 300, for example, for starting, navigating and driving the vehicle 1000.

[0039] In some embodiments of the present application, the battery 100 can serve not only as an operating power source for the vehicle 1000, but also as a driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0040] The technical solutions of the vehicle body and vehicle 1000 provided in the specific implementation manner of this application are further explained below.

[0041] Some embodiments of the present application provide a vehicle body, as shown in Figure 2, which includes a beam body 1 and a load-bearing plate 2, the load-bearing plate 2 being detachably connected to the beam body 1, one side of the load-bearing plate 2 being used to support a seat, and a recessed structure 20 being formed on the side of the load-bearing plate 2 facing away from the seat.

[0042] The vehicle body may refer to the portion of vehicle 1000 used to carry passengers and cargo. For example, the vehicle body may form the space in which the driver and passengers sit. The beam 1 may be the main frame of the vehicle body, possessing excellent rigidity and strength. Components such as the floor, doors, and windows of the vehicle body are connected to the beam 1, supporting and securing these components.

[0043] The load plate 2 can be a plate-shaped component in the vehicle body. For example, it can be a structural component of the floor panel used to support and carry the seats. One side of the load plate 2 is used to support the seats. The seats can be connected to one side of the load plate 2, allowing the load plate 2 to bear the load of the seats and their occupants.

[0044] For example, the load-bearing plate 2 can be made of a steel plate using a stamping process, so that the load-bearing plate 2 has good strength, which is beneficial to improving the load-bearing capacity of the vehicle body.

[0045] The recessed structure 20 may be a structure formed by a side of the support plate 2 facing away from the seat, which is recessed toward the seat. For example, the recessed structure 20 may be formed by stamping the support plate 2, such that a portion of the support plate 2 is deformed from the side facing away from the seat toward the side facing the seat.

[0046] In the above structure, since the supporting plate 2 is detachably connected to the beam body 1, the recessed structure 20 formed by the side of the supporting plate 2 facing away from the seat can be opened as the supporting plate 2 is removed, so that the electromechanical equipment in the vehicle 1000 can be conveniently arranged in the recessed structure 20, which is beneficial to improving the utilization rate of the space in the vehicle 1000.

[0047] In some embodiments, the beam body 1 is connected to a side of the supporting plate 2 facing away from the seat.

[0048] The beam body 1 is connected to the side of the supporting plate 2 facing away from the seat. The beam body 1 can be located on the side of the supporting plate 2 facing away from the seat, and the side of the supporting plate 2 facing away from the seat is attached to and connected to the beam body 1, so that the supporting plate 2 can be easily approached and connected to the beam body 1 from one side of the beam body 1.

[0049] In some embodiments, as shown in FIG3 , a support 21 is provided on a side of the supporting plate 2 facing the seat, and the support 21 is used to connect to the seat.

[0050] The support 21 can be a seat structure provided on the load-bearing plate 2, which is used to be connected to the seat. By arranging the support 21 on the side of the load-bearing plate 2 towards the seat, the seat can be connected to the load-bearing plate 2 through the support 21.

[0051] In some embodiments, the support 21 can be a separate seat structure connected to the support plate 2. For example, the support 21 can be welded to the side of the support plate 2 facing the seat, ensuring a secure connection between the support 21 and the support plate 2 and improving the strength of the connection between the support plate 2 and the seat. In some embodiments, the support 21 can also be connected to the support plate 2 via bolts, making it removable from the support plate 2 and facilitating replacement.

[0052] In some embodiments, the support 21 can be a structure in which the material forming the support 21 is integrally molded onto the carrier plate 2. In other words, the support 21 and the carrier plate 2 are an integrally molded structure. For example, the support 21 can be manufactured simultaneously with the carrier plate 2 using an integral molding method such as casting, allowing the support 21 and the carrier plate 2 to be manufactured as a whole. This not only facilitates the processing and manufacturing of the support 21, but also reduces the number of parts in the vehicle body and improves the connection strength between the support 21 and the carrier plate 2. The support 21 can also be manufactured simultaneously with the carrier plate 2 using a machining method such as milling, by machining a single piece of blank.

[0053] For example, the support 21 integrally formed on the supporting plate 2 can be located as a whole on the side of the supporting plate 2 facing the seat, or can pass through the supporting plate 2 along the thickness direction of the supporting plate 2, with part of the support 21 located on the side of the supporting plate 2 facing the seat, and part of the support 21 located on the side of the supporting plate 2 facing away from the seat, and the seat is connected to the part of the support 21 located on the side of the supporting plate 2 facing the seat.

[0054] In some embodiments, as shown in FIG. 4 , the supporting plate 2 is provided with a first reinforcing rib 22 , and the first reinforcing rib 22 is provided on a side of the supporting plate 2 facing the seat and / or a side facing away from the seat.

[0055] The first reinforcing ribs 22 may be convex rib structures for increasing the structural strength of the load-bearing plate 2. Providing the first reinforcing ribs 22 on the load-bearing plate 2 increases the material content of the load-bearing plate 2, thereby improving the structural strength of the load-bearing plate 2 and enabling the load-bearing plate 2 to better bear the load of the seat and the person sitting in the seat.

[0056] The first reinforcing rib 22 is arranged on the side of the supporting plate 2 facing the seat and / or the side away from the seat. The reinforcing rib may be protruding from the side of the supporting plate 2 facing the seat in the direction where the seat is located, or the reinforcing rib may be protruding from the side of the supporting plate 2 facing away from the seat in the direction away from the seat, or the reinforcing rib may be protruding from both the side of the supporting plate 2 facing the seat and the side of the supporting plate 2 facing away from the seat.

[0057] For example, there may be a plurality of first reinforcing ribs 22 , some of which extend in the forward direction of the vehicle 1000 , and some of which extend in the left-right direction of the vehicle 1000 .

[0058] In some embodiments, the vehicle body further includes a connecting member, the load-bearing plate 2 is provided with a first connecting hole 23 , and the connecting member passes through the first connecting hole 23 and is connected to the beam body 1 .

[0059] The connecting member may be a component that detachably connects the load-bearing plate 2 to the beam body 1. For example, the connecting member may include a connecting pin, a connecting bolt, etc. The connecting member such as the connecting pin, the connecting bolt, etc. not only allows the load-bearing plate 2 to be conveniently and detachably connected to the beam body 1, but also improves the reliability and firmness of the connection between the load-bearing plate 2 and the beam body 1.

[0060] The first connection hole 23 can be a through hole opened along the thickness direction of the load-bearing plate 2 for passing a connecting piece through which the connecting piece passes and is connected to the beam body 1 to connect the load-bearing plate 2 to the beam body 1 .

[0061] In some embodiments, the supporting plate 2 is provided with a connecting boss 24 . The connecting boss 24 protrudes toward a side of the supporting plate 2 facing away from the seat. The first connecting hole 23 is defined in the connecting boss 24 .

[0062] The connecting boss 24 can be a structure in the support plate 2 that protrudes toward the side facing away from the seat. In some embodiments, the connecting boss 24 can be fitted to the beam body 1, thereby ensuring a stable connection between the beam body 1 and the support plate 2. By deforming the connecting boss 24 so that it protrudes toward the side facing away from the seat, not only does it impart a certain amount of prestress to the connecting boss 24, which helps to improve the structural strength of the connecting boss 24, but it also allows the support plate 2 to better fit the beam body 1 through the connecting boss 24. By providing the first connecting hole 23 in the connecting boss 24 with higher structural strength, the connector can more securely connect the support plate 2 and the beam body 1.

[0063] In some embodiments, the supporting plate 2 is provided with a second reinforcing rib 25 , and the second reinforcing rib 25 is located on the connecting boss 24 .

[0064] The second reinforcing rib 25 may be a rib structure for improving the structural strength of the connecting boss 24. By providing the second reinforcing rib 25 on the connecting boss 24, the material in the connecting boss 24 is increased, which can improve the structural strength of the connecting boss 24 and provide the connecting boss 24 with better structural strength.

[0065] In some embodiments, the beam body 1 includes a first beam 11 and a second beam 12 spaced apart, the load-bearing plate 2 is connected to the first beam 11 and the second beam 12 , and the recessed structure 20 is located between the first beam 11 and the second beam 12 , and is used to accommodate electromechanical equipment.

[0066] The first beam 11 and the second beam 12 may be partial structures of the beam body 1. The first beam 11 and the second beam 12 may be beam-like structures spaced apart in the forward direction of the vehicle 1000 in the beam body 1. The load-bearing plate 2 is detachably connected to the first beam 11 and the second beam 12, so that the load-bearing plate 2 can be detachably connected to the beam body 1.

[0067] By locating the recessed structure 20 in the gap between the first beam 11 and the second beam 12 , the first beam 11 and the second beam 12 are less likely to block the recessed structure 20 , thereby facilitating the recessed structure 20 to accommodate electromechanical equipment.

[0068] The recessed structure 20 is located above the chassis of the vehicle 1000. The electromechanical equipment it accommodates may be an on-board charger, a power converter, a battery 100 management module, a motor controller 200 and other devices, which is beneficial to improving the utilization rate of the space in the vehicle 1000, thereby improving the compactness of the vehicle 1000.

[0069] In some embodiments, the supporting plate 2 is an integrally formed structure.

[0070] The carrier plate 2 is configured as an integrally formed structure, which may mean that the carrier plate 2 is manufactured using an integral forming method such as casting or stamping, so that the structures in the carrier plate 2 can be manufactured as a whole and simultaneously, which not only facilitates the processing and manufacturing of the carrier plate 2 but also ensures that the overall structure of the carrier plate 2 has good strength. The carrier plate 2 can be manufactured by machining a whole piece of blank using a machining method such as milling, which makes the carrier plate 2 easy to process. For example, the carrier plate 2 can be made of aluminum or an aluminum alloy, so that the carrier plate 2 has good strength and is light in weight.

[0071] In some embodiments, the carrier plate 2 may be integrally formed using an injection molding process, so that the carrier plate 2 is configured as a plastic structure, which not only reduces the weight of the carrier plate 2 but also helps reduce the cost of the carrier plate 2 .

[0072] The plastic structure may be a structure made of thermoplastic plastic, which can be manufactured using a thermoplastic plastic injection molding process. The plastic structure may also be a composite material formed of thermoplastic plastic and fiber. For example, the thermoplastic plastic may include at least one of polyethylene, polyvinyl chloride, polypropylene, polystyrene, polyoxymethylene, etc. The fiber may be glass fiber, which has excellent insulation properties, strong heat resistance, good corrosion resistance, and high mechanical strength. By coating the glass fiber with thermoplastic plastic, the glass fiber and the coated thermoplastic plastic can be formed by hot pressing.

[0073] Some embodiments of the present application also provide a vehicle 1000 , which includes a vehicle body provided by the above technical solution.

[0074] The vehicle 1000 may be the electric vehicle 1000 provided by the aforementioned technical solution, or may be the fuel vehicle or gas vehicle provided by the aforementioned technical solution.

[0075] Some embodiments of the present application provide a vehicle body, comprising a beam 1, a load-bearing plate 2, and a connector. A support 21 is provided on one side of the load-bearing plate 2 for connecting to a seat. A connecting boss 24 is provided on the side of the load-bearing plate 2 facing away from the seat. The connecting boss 24 is provided with a first connecting hole 23, through which the connector passes to removably connect the load-bearing plate 2 to the beam 1. A first reinforcing rib 22 is provided on the side of the load-bearing plate 2 facing away from the seat, and a second reinforcing rib 25 is provided on the side of the load-bearing plate 2 facing the seat. The second reinforcing rib 25 is provided on the connecting boss 24. The load-bearing plate 2 is constructed of plastic, and a recessed structure 20 is formed on the side of the load-bearing plate 2 facing away from the seat to accommodate electromechanical equipment. Because the recessed structure 20 formed on the side of the load-bearing plate 2 facing away from the seat can be opened upon removal of the load-bearing plate 2, electromechanical equipment in the vehicle 1000 can be conveniently arranged in the recessed structure 20, thereby improving space utilization within the vehicle 1000.
