The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0021] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0022] In related technologies, the manufacturing methods of engine compartment assemblies are generally divided into two types: integral casting using aluminum alloy materials to obtain an integrated cast aluminum structure; and assembling multiple sheet metal parts into a fully sheet metal engine compartment assembly. However, the manufacturing process of large integrated cast aluminum structures is complex and the production cost is high; in fully sheet metal engine compartment assemblies, the number and state of parts are large, the integration is low, and the overall weight is large. How to balance reducing the production cost of engine compartment assemblies and ensuring integration is a problem that urgently needs to be solved. To solve the above problems, embodiments of the present invention propose an engine compartment assembly, a body, and a vehicle. The engine compartment assembly, body, and vehicle mentioned above are described in detail below.

[0023] Reference Figures 1 to 7 The nacelle assembly provided in this embodiment of the invention includes a nacelle casting 1, a nacelle longitudinal beam 2, and a wheel hub 3. The nacelle longitudinal beam 2 is at least connected to the nacelle casting 1, and the wheel hub 3 is connected to both the nacelle casting 1 and the nacelle longitudinal beam 2. The nacelle casting 1 is made of aluminum alloy and is an integrally cast structure. The nacelle longitudinal beam 2 is made of steel, and the wheel hub 3 is made of steel.

[0024] The nacelle assembly has a first direction and a second direction, the first direction being perpendicular to the second direction. The first direction can be referenced. Figure 1 and Figure 2 The Y-arrow in the image indicates the direction; a second direction can be referenced. Figure 1 and Figure 2 The direction indicated by the X arrow is as follows. The nacelle longitudinal beam 2 extends along the X direction. There are two nacelle longitudinal beams 2, symmetrically arranged along the Y direction. There are two wheel hub packages 3, symmetrically arranged along the Y direction.

[0025] Along the X direction, the nacelle longitudinal beam 2 is connected to the front end of the nacelle casting 1. The connection method between the rear end of the nacelle longitudinal beam 2 and the nacelle casting 1 may include at least one of bolt connection, flow drill screw connection, welding, and riveting. For example, the connection method between the nacelle longitudinal beam 2 and the nacelle casting 1 may include bolt connection and flow drill screw connection.

[0026] The wheel hub assembly 3 can be connected to the engine compartment casting 1 by bolting, drilling screw connection, welding, riveting, etc. For example, the wheel hub assembly 3 can be connected to the engine compartment casting 1 by bolting. The wheel hub assembly 3 can be connected to the engine compartment longitudinal beam 2 by bolting, drilling screw connection, welding, riveting, etc. For example, the wheel hub assembly 3 can be connected to the engine compartment longitudinal beam 2 by welding.

[0027] Both the engine compartment longitudinal beam 2 and the wheel hub 3 are made of steel, meaning they are sheet metal parts. The engine compartment casting 1 includes a first connecting part 101, a second connecting part 102, a third connecting part 103, a lower crossbeam 104, and a main body 105. The engine compartment casting 1 is formed using a one-piece casting technology, which die-casts the first connecting part 101, the second connecting part 102, the third connecting part 103, the lower crossbeam 104, and the main body 105 into a single unit. One-piece casting technology offers advantages such as shortening production line time, reducing overall vehicle weight, and increasing the range of electric vehicles.

[0028] In this embodiment of the invention, the engine compartment assembly includes a connected engine compartment casting 1, engine compartment longitudinal beams 2, and wheel hubs 3. Compared to a large, integrated cast aluminum structure, the engine compartment casting 1 in this embodiment is relatively small in size and easy to cast. The engine compartment longitudinal beams 2 and wheel hubs 3 are both made of steel, and the material cost of steel is lower than that of aluminum alloy, thus reducing the overall production cost of the engine compartment assembly. Compared to a fully sheet metal engine compartment assembly, in this embodiment, the engine compartment casting 1 integrates multiple parts into a single unit, reducing the number and state of the overall engine compartment assembly, ensuring integration, reducing development costs, increasing the welding cycle time of the parts in the engine compartment assembly on the welding production line, and reducing the overall weight of the engine compartment assembly. In summary, the engine compartment assembly provided by this embodiment of the invention possesses the advantages of integrated casting technology, while reducing development and production costs and ensuring integration. Furthermore, the engine compartment longitudinal beams 2 are sheet metal parts, which, compared to cast aluminum structures, have better energy absorption and buffering effects, enabling the vehicle to meet collision safety performance and strength requirements.
