[0034] The front bulkhead assembly 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0035] like Figures 1-3As shown, a front bulkhead assembly 100 according to an embodiment of the present invention is used in a vehicle. The front bulkhead assembly 100 includes longitudinal beams 1, a front bulkhead body 2, and connecting components 3. The longitudinal beams 1 extend along the longitudinal direction of the vehicle and there are two of them. The two longitudinal beams 1 are spaced apart along the left-right direction of the vehicle. The front bulkhead body 2 is located between the two longitudinal beams 1. Both ends of the front bulkhead body 2 along the left-right direction are respectively connected to the two longitudinal beams 1. At least one end of the front bulkhead body 2 along the left-right direction is connected to the longitudinal beam 1 through the connecting components 3.

[0036] Therefore, by connecting the two ends of the front bulkhead body 2 along the left and right directions to the two longitudinal beams 1 respectively, the impact force on the front bulkhead assembly 100 can be well transmitted in the left and right directions. At the same time, during the transmission of expansion force, it can be distributed to all directions of the vehicle through the front bulkhead body 2 and the longitudinal beams 1, so as to avoid the impact force being too concentrated, reduce the deformation of local structures, and make the front bulkhead assembly 100 and the vehicle using the front bulkhead assembly 100 more robust, effectively improving the impact resistance and safety.

[0037] Specifically, the front bulkhead body 2 is located in front of the vehicle's cab. When the front of the vehicle is impacted, the front bulkhead body 2 is adapted to distribute the impact force in different directions to avoid excessive local concentration of force on the front bulkhead body 2, which could lead to intrusion into the vehicle interior. Therefore, in this application, by connecting the two ends of the front bulkhead body 2 along the left and right directions to two longitudinal beams 1 respectively, the impact force received by the front bulkhead body 2 can be effectively dispersed to the two longitudinal beams 1, and then diffused to the entire vehicle, thereby effectively reducing the deformation of the front bulkhead, i.e., reducing the amount of intrusion of the front bulkhead, and ensuring the safety of the vehicle interior.

[0038] Meanwhile, at least one end of the front bulkhead body 2 along its left and right directions is connected to the longitudinal beam 1 via a connecting assembly 3, thus indirectly connecting the front bulkhead body 2 and the longitudinal beam 1. This effectively enhances the connection strength between the front bulkhead body 2 and the longitudinal beam 1, and the connecting assembly 3 can absorb some of the collision energy, reducing the impact on the front bulkhead body 2 and the longitudinal beam 1, further improving the vehicle's impact resistance. Furthermore, when the vehicle is damaged and requires repair, the connecting assembly 3 allows for relatively easy disassembly and replacement of the front bulkhead body 2 and the longitudinal beam 1, effectively reducing repair costs and difficulty.

[0039] For example, the left or right end of the front bulkhead body 2 is connected to the corresponding longitudinal beam 1 via a connecting assembly 3; or, as... Figure 1 and- Figure 3 As shown, the front bulkhead body 2 is connected to the longitudinal beam 1 at both ends along the left and right directions via connecting components 3.

[0040] According to the embodiment of the present invention, the front bulkhead assembly 100 includes two longitudinal beams 1 extending along the longitudinal direction of the vehicle and spaced apart along the left-right direction. The front bulkhead body 2 is located between the two longitudinal beams 1 and is connected to the two longitudinal beams 1 at both ends along the left-right direction. At least one end of the front bulkhead body 2 along the left-right direction is connected to the longitudinal beam 1 via a connecting component 3. This allows the impact force on the front bulkhead assembly 100 to be effectively transmitted along the left-right direction, effectively preventing the impact force from being too concentrated, reducing the deformation of local structures, and making the front bulkhead assembly 100 and the vehicle using the front bulkhead assembly 100 more robust, improving impact resistance and safety. At the same time, the connecting component 3 effectively enhances the connection strength between the front bulkhead body 2 and the longitudinal beams 1, and allows the front bulkhead body 2 and the longitudinal beams 1 to be relatively easy to disassemble and replace, effectively reducing maintenance costs and difficulty.

[0041] In some embodiments of this utility model, such as Figure 3 , Figure 4 and Figure 6 As shown, the front bulkhead body 2 includes a first section 21 and a second section 22. The first section 21 is inclined forward from top to bottom, and at least one end of the first section 21 in the left and right directions is connected to the longitudinal beam 1 through the connecting assembly 3. The second section 22 extends in the vertical direction of the vehicle and its lower end is connected to the first section 21. The two ends of the second section 22 in the left and right directions are spliced ​​and connected to the two longitudinal beams 1 respectively.

[0042] Understandably, the forward tilt of the first segment 21 from top to bottom helps optimize airflow in the vehicle, guiding it to flow more smoothly over the bottom of the body, thereby reducing airflow resistance and turbulence. Thus, the connection between the tilted first segment 21 and the longitudinal beam 1 is achieved through the connecting component 3, effectively ensuring the connection strength between the first segment 21 and the longitudinal beam 1, thereby improving the overall structural strength of the front bulkhead assembly 100. Simultaneously, the second segment 22, by splicing and connecting to the two longitudinal beams 1 at both ends in the left and right directions, further enhances the connection strength between the front bulkhead body 2 and the two longitudinal beams 1, thereby improving the overall structural strength of the front bulkhead assembly 100. Optionally, the second segment 22 and the longitudinal beam 1 can be connected using structural adhesive or self-piercing rivets.

[0043] In some embodiments of this utility model, such as Figure 3 and Figure 4As shown, the connecting assembly 3 includes a connecting plate 31. The connecting plate 31 is located on the front side of the front bulkhead body 2 and extends in the front-rear direction. The connecting plate 31 is connected to both the longitudinal beam 1 and the first segment 21. Thus, the first segment 21 is connected to the longitudinal beam 1 via the connecting plate 31, thereby achieving an indirect connection between the front bulkhead body 2 and the longitudinal beam 1. Simultaneously, the connecting plate 31 has a simple structure, effectively reducing the cost of the front bulkhead assembly 100. Optionally, the connecting plate 31 and the first segment 21 can be connected using structural adhesive or self-piercing rivets, and the connecting plate 31 and the longitudinal beam 1 can be connected using structural adhesive or self-piercing rivets.

[0044] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the connecting plate 31 is located above the first section 21, and the rear end of the connecting plate 31 also has an upwardly bent flange 311, which is connected to the second section 22 and the longitudinal beam 1 respectively. Thus, the flange 311 further improves the connection strength between the second section 22 and the longitudinal beam 1, and further improves the connection strength between the front bulkhead body 2 and the longitudinal beam 1, thereby improving the overall structural strength of the front bulkhead assembly 100.

[0045] In some embodiments of this utility model, such as Figure 3 , Figure 5 and Figure 6 As shown, the connecting assembly 3 includes a connector 32. The connector 32 is located on the rear side of the front bulkhead body 2. One end of the connector 32 in the left-right direction is connected to the longitudinal beam 1, and the other end is connected to the first segment 21 and the second segment 22. Thus, the connector 32, located on the rear side of the front bulkhead body 2, achieves an indirect connection between the longitudinal beam 1 and the front bulkhead body 2, effectively ensuring the connection strength between the front bulkhead body 2 and the longitudinal beam 1, thereby improving the overall structural strength of the front bulkhead assembly 100. Optionally, the connector 32 can be connected to the first segment 21 and the second segment 22 using structural adhesive or self-piercing rivets, and the connector 32 can be connected to the longitudinal beam 1 using structural adhesive or self-piercing rivets.

[0046] In some embodiments of this utility model, such as Figure 3 , Figure 5 and Figure 6 As shown, the lower surface of the first segment 21 includes a first sub-surface 211 and a second sub-surface 212. The first sub-surface 211 extends in the front-back direction, and the second sub-surface 212 is inclined forward in the top-to-bottom direction. The connector 32 is connected to the second segment 22 and the second sub-surface 212, and the longitudinal beam 1 is connected to the first sub-surface 211 and the second sub-surface 212.

[0047] Thus, by connecting the connector 32 to the second segment 22 and the second sub-surface 212, one end of the connector 32 in the left and right directions is connected to the first segment 21 and the second segment 22, and by connecting the longitudinal beam 1 to the first sub-surface 211 and the second sub-surface 212, the connection strength between the longitudinal beam 1 and the front bulkhead body 2 is further improved, and the overall structural strength of the front bulkhead assembly 100 is improved.

[0048] In some embodiments of this utility model, such as Figure 3 , Figure 5 and Figure 6 As shown, the upper end of the second segment 22 has an upwardly extending extension plate 221, and the connector 32 is connected to the extension plate 221. Therefore, the connection between the connector 32 and the front bulkhead body 2 is further strengthened by connecting the connector 32 to the extension plate 221, thereby improving the overall structural strength of the front bulkhead assembly 100. Simultaneously, the front bulkhead assembly 100 also includes a front bulkhead connecting plate 4, which is located above the front bulkhead body 2 and the two longitudinal beams 1. The front bulkhead connecting plate 4 is connected to the extension plate 221, thus providing a connection point for the front bulkhead connecting plate 4 through the extension plate 221, reducing the difficulty of connection and assembly.

[0049] In some embodiments of this utility model, such as Figure 6 As shown, the front bulkhead body 2 has a cavity 23, and the cavity 23 has multiple reinforcing ribs 24, which divide the cavity 23 into multiple sub-cavities. Thus, the cavity 23 can absorb and offset part of the collision energy received by the front bulkhead body 2, reduce the impact on the front bulkhead body 2, and improve the structural strength of the front bulkhead body 2. Furthermore, the multiple reinforcing ribs 24 in the cavity 23 further enhance the structural strength of the front bulkhead body 2.

[0050] In some embodiments of this utility model, the front bulkhead body 2 is an extruded part. Thus, the front bulkhead body 2 is manufactured through an extrusion molding process, resulting in an integrated structure. The manufacturing process is simple and easy to operate, and the strength is high. It eliminates the need for multiple sets of molds, reducing the number of parts required in the manufacturing process and lowering manufacturing costs. Optionally, the front bulkhead body 2 is an extruded aluminum alloy part.

[0051] In some embodiments of this utility model, the longitudinal beam 1 is a die-cast part. It is understood that, since the longitudinal beam 1 needs to withstand the impact and torque forces at the front of the vehicle body, it requires high strength and rigidity. The die-cast longitudinal beam 1 can meet these performance requirements, and the die-casting process has high production efficiency, typically requiring minimal subsequent processing, and can quickly manufacture a large number of castings, thereby reducing production costs. Optionally, the front bulkhead body 2 is an aluminum alloy die-cast part.

[0052] In some embodiments of this utility model, the connecting component 3 is a stamped part. It is understood that stamped parts have advantages such as lightweight and low cost while ensuring a certain structural strength. Therefore, by using a stamped part for the connecting component 3, the cost and weight of the front bulkhead assembly 100 are reduced while ensuring the indirect connection between the longitudinal beam 1 and the front bulkhead body 2, which helps to achieve vehicle lightweighting.

[0053] In some embodiments of this utility model, such as Figures 1-3 As shown, the front bulkhead assembly 100 also includes a front bulkhead connecting plate 4. The front bulkhead connecting plate 4 is located above the front bulkhead body 2 and the two longitudinal beams 1, and is connected to the upper end of the front bulkhead body 2. The front bulkhead connecting plate 4 is a stamped part. It is understood that the front bulkhead connecting plate 4 needs to meet basic installation requirements. The front bulkhead body 2 is a critical part for collision safety. Therefore, this arrangement satisfies the different structural strength requirements of different parts of the front bulkhead assembly 100. Furthermore, using a stamped part for the front bulkhead connecting plate 4 reduces the cost and weight of the front bulkhead assembly 100, contributing to vehicle lightweighting. Optionally, the front bulkhead body 2 and the front bulkhead connecting plate 4 can be connected using structural adhesive or self-piercing rivets.

[0054] In some embodiments, the front bulkhead body 2 is an extruded part, the front bulkhead connecting plate 4 is a stamped part, the longitudinal beam 1 is a die-cast part, and the connecting assembly 3 is a stamped part. It is understood that the front bulkhead connecting plate 4 needs to meet basic installation requirements. The front bulkhead body 2 is a critical component for collision safety. By using an extruded part for the front bulkhead body 2 and a die-cast part for the longitudinal beam 1, the structural strength of the front bulkhead body 2 is effectively improved. Furthermore, by using a stamped part for the front bulkhead connecting plate 4 and the connecting assembly 3, the cost and weight of the front bulkhead assembly 100 are effectively reduced, contributing to vehicle lightweighting.

At least one end of the front bulkhead body 2 along the left-right direction is connected to the longitudinal beam 1 via a connecting assembly 3. This allows the impact force on the front bulkhead assembly 100 to be effectively transmitted along the left-right direction, effectively preventing excessive integration of impact force, reducing local structural deformation, making the vehicle more robust, and improving its impact resistance and safety. Simultaneously, the connecting assembly 3 effectively enhances the connection strength between the front bulkhead body 2 and the longitudinal beams 1, and allows for relatively easy disassembly and replacement of the front bulkhead body 2 and the longitudinal beams 1, effectively reducing maintenance costs and difficulty.
