The second reinforcing beam connecting part 22 and the third reinforcing beam connecting part 23 are respectively connected to the upper plate 1 of the front wall panel.

[0061] In this embodiment, the second connecting part 32 of the bracket and the first connecting part 21 of the reinforcing beam form a two-layer weld. Part of the third connecting part 33 of the bracket forms a three-layer weld with the upper end of the second connecting part 22 of the reinforcing beam, the upper end of the third connecting part 23 of the reinforcing beam, and the upper plate 1 of the front wall panel.

The lower front bulkhead plate 6 and the rear section of the naval longitudinal beam 7 are integrally formed parts, and the upper end of the lower front bulkhead plate 6 is fixedly connected to the lower end of the upper front bulkhead plate 1.

[0083] In this embodiment, the front panel upper plate 1 and the front panel lower plate 6 are separate structures, while the front panel lower plate 6 and the rear section 7 of the engine compartment longitudinal beam are integrally formed. The front panel lower plate 6 and the rear section 7 of the engine compartment longitudinal beam can be manufactured to fit different vehicle models. By simply replacing the front panel upper plate 1, the front panel assembly can be adapted to different vehicle models and different layout requirements, such as sedans, SUVs, left-hand drive vehicles, and right-hand drive vehicles. In other words, the front panel assembly has a wider range of applications and stronger versatility.

[0084] In some embodiments, the lower front panel 6 and the rear section of the engine compartment longitudinal beam 7 are integrated cast aluminum structural components. This integration satisfies both collision and CAE performance requirements, as well as the installation requirements for vehicle steering, air conditioning, and accelerator pedals. Furthermore, compared to traditional sheet metal designs, integrated cast aluminum reduces weight, which is an important way to increase the driving range of new energy vehicles. In addition, the integrated cast aluminum lower front panel 6 reduces hundreds of weld points and integrates dozens of parts, reducing manufacturing processes while meeting modular design requirements.

[0085] In some embodiments, the lower front panel 6 is symmetrically arranged along the middle of the lower front panel 6, thus making the structure of the lower front panel 6 more versatile and applicable to both left-hand drive and right-hand drive vehicles.

[0086] In some embodiments, the front bulkhead assembly includes an upper front bulkhead plate 1, a first reinforcing beam 2, a first wiper bracket 3, a second reinforcing beam 4, a reinforcing plate 5, a lower front bulkhead plate 6, a rear section of the nacelle longitudinal beam 7, and a second wiper bracket 8. The assembly process of the front bulkhead assembly is as follows.

[0087] First, the first reinforcing beam 2 and the first wiper bracket 3 are welded together to form the first sub-assembly. As an example, the second connecting part 32 of the bracket of the first wiper bracket 3 is welded to the first connecting part 21 of the reinforcing beam of the first reinforcing beam 2 to form the first sub-assembly.

[0088] The first sub-assembly is welded to the front panel 1. As an example, the fifth connecting part 15 of the upper plate of the front panel 1 is welded to the first connecting part 31 of the first wiper bracket 3 to form a two-layer weld. The fourth connecting part 14 of the upper plate of the front panel 1 is welded to the third connecting part 33 of the first wiper bracket 3, the upper end of the second connecting part 22 of the first reinforcing beam 2, and the upper end of the third connecting part 23 of the reinforcing beam to form a three-layer weld. The portion of the second connecting part 22 of the reinforcing beam that forms the three-layer weld is welded to the sixth connecting part 16 and the third connecting part 13 of the upper plate of the front panel 1 to form a two-layer weld. The portion of the third connecting part 23 of the reinforcing beam that forms the three-layer weld is welded to the sixth connecting part 16 and the third connecting part 13 of the upper plate of the front panel 1 to form a two-layer weld. Thus, as shown... Figure 8 As shown, the front panel assembly forms a first chamber 91 and a second chamber 92. The first chamber 91 and the second chamber 92 not only ensure the rigidity of the wiper mounting point, but also further improve the strength of the front panel assembly in the front-rear direction.

[0089] The second reinforcing beam 4 is welded to the upper plate 1 of the front wall panel. As an example, the first connecting part 11 of the upper plate of the front wall panel 1 is welded to the fourth connecting part 41 of the reinforcing beam of the second reinforcing beam 4, and the eighth connecting part 18 of the upper plate of the front wall panel 1 is welded to the fifth connecting part 42 of the reinforcing beam of the second reinforcing beam 4. Due to welding channel limitations, some overlapping surfaces cannot be welded and must be connected by open-hole welding. For example, a first weld hole 43 is provided on the fifth connecting part 42 of the reinforcing beam of the second reinforcing beam 4. Furthermore, the portion of the fifth connecting part 42 of the reinforcing beam of the second reinforcing beam 4 is connected to the eighth connecting part 18 of the upper plate, the fourth connecting part 34 of the first wiper bracket 3, and the fifth connecting part 35 of the bracket using a three-layer weld. Figure 8 As shown, the front panel assembly forms a third chamber 93, which effectively improves the strength of the front panel assembly during a collision and further enhances the rigidity of the front panel assembly.

[0090] The second wiper bracket 8 is welded to the upper plate 1 of the front wall panel. As an example, the bracket flange 81 of the second wiper bracket 8 is welded to the seventh connecting part 17 of the upper plate on the upper plate 1 of the front wall panel. The bracket flange 81, together with the eighth connecting part 18 of the upper plate on the front wall panel 1 and the fifth connecting part 42 of the reinforcing beam of the second reinforcing beam 4, forms a three-layer welded connection, which further improves the rigidity of the wiper mounting point.

[0091] The reinforcing plate 5 is welded to the upper plate 1 of the front wall panel. As an example, the second connecting portion 52 of the reinforcing plate 5 is welded to the ninth connecting portion 19 of the upper plate of the front wall panel 1 in two layers. A three-layer weld is formed by the first connecting portion 51 of the reinforcing plate 5, the eighth connecting portion 18 of the upper plate of the front wall panel 1, and the fifth connecting portion 42 of the reinforcing beam. Due to limitations in the welding channel, further welding is performed to the second reinforcing beam 4 through the second weld hole 53 of the reinforcing plate 5. In some embodiments, the reinforcing plate 5 is the last component installed, greatly ensuring the accuracy of the brake pump mounting point connected to the reinforcing plate 5.

[0092] Finally, the above-mentioned welded structure is connected to the lower front panel 6. In order to better ensure the precision control of the brake mounting point, the upper plate second connecting part 12 of the upper front panel 1 and the lower plate connecting part 61 of the lower front panel 6 are connected by riveting, thus forming the front panel assembly structure.

[0093] The front bulkhead assembly structure implemented in this application has a front bulkhead upper plate 1 and a front bulkhead lower plate 6 set separately. The front bulkhead lower plate 6 is integrally formed with the rear section 7 of the engine compartment longitudinal beam. This not only ensures the modularity and universality requirements, but also ensures the flexibility of the front bulkhead upper plate to adapt to left and right rudder, sedan and SUV development. While meeting the installation requirements, it can effectively guarantee the performance requirements.

[0094] In some embodiments, the front panel upper plate 1, the first reinforcing beam 2, the first wiper bracket 3, the second reinforcing beam 4, the reinforcing plate 5 and the second wiper bracket 8, as well as the front panel lower plate 6 and the rear section of the engine compartment longitudinal beam 7 are integrally formed cast aluminum structures. That is, the front panel assembly adopts a combination of high-pressure casting and stamping processes, which effectively reduces the manufacturing steps of the front panel assembly, simplifies the manufacturing process, and fully utilizes the advantages of high-pressure casting aluminum, such as high dimensional accuracy, less post-processing, high stamping production efficiency, and good strength and rigidity.

[0095] Moreover, the front panel assembly adopts a combination of cast aluminum and sheet metal, making full use of the advantages of cast aluminum such as lightweight and corrosion resistance, and sheet metal such as low cost and strong plasticity, thus achieving weight reduction of the front panel assembly, which greatly helps to improve the driving range of new energy vehicles.

[0096] The front panel assembly structure implemented in this application adopts a connection method combining riveting and welding. It fully utilizes the advantages of riveting, which does not involve high-temperature melting and retains the original properties of the material, and can connect different materials, as well as the advantages of welding, which has high strength and light weight. This effectively ensures the vehicle's requirements for high performance and lightweight design. Moreover, the absence of numerous pre-drilled mounting holes provides better noise insulation and improves the passenger compartment's ride comfort.

[0097] The front wall panel assembly implemented in this application has a lower front wall panel 6 symmetrically arranged along the middle of the lower front wall panel 6, and the lower front wall panel 6 and the rear section 7 of the engine compartment longitudinal beam are integrally formed. By overlapping the upper front wall panel 1 in different states, the front wall panel assembly can achieve universality in left-hand drive vehicles, right-hand drive vehicles, sedans, and SUVs, reducing the number of component states and lowering component weight, which is conducive to achieving vehicle lightweighting and modularization. (Refer to...) Figure 11 The image shows the application of the front panel assembly in right-hand drive vehicles and SUVs. For example... Figure 12 The image shows the application of the front panel assembly in left-hand drive vehicles and passenger cars.

[0098] This embodiment also proposes an automobile, including a vehicle body, the vehicle body having the aforementioned front wall panel assembly.

[0099] The automobile of this utility model, through the setting of the front wall panel assembly, has high safety, good lightweight and modularity. Moreover, by simply overlapping the front wall panel upper plate 1 in different states on the lower front wall panel 6, it can be adapted to left-hand drive, right-hand drive, sedan and SUV models, etc., with strong flexibility and can effectively guarantee performance requirements.

[0100] In this embodiment, the front panel assembly and the vehicle can be referenced to each other and have the same or similar beneficial effects as any of the aforementioned front panel assemblies. To avoid repetition, they will not be described again here.

[0101] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
