[0034] With the increasing popularity of electric vehicles, people have higher and higher requirements for their collision safety. The longitudinal beams and lower crossbeams of the engine compartment are the main force transmission structures of the vehicle body and are extremely important collision force transmission paths, with functions such as absorbing collision energy, protecting the driver, and protecting electrical components such as the battery. In the existing technology, the longitudinal beams and lower crossbeams of the engine compartment are connected to each other through joint structures. To meet higher collision performance, it is necessary to increase the cross-section or material thickness of the joint structure. Although this can meet the performance target requirements, it encroaches on external space and is not conducive to the assembly of surrounding parts.

[0035] To address the related technical problems, this application provides a vehicle that includes the following front assembly.

[0036] To address the related technical problems, this application also provides a front assembly, see [link to relevant documentation]. Figures 1 to 5 , Figure 1 This is a schematic diagram of an embodiment of the front assembly provided in this application. Figure 2 yes Figure 1 The diagram shows a structural schematic of one embodiment of the cabin longitudinal beam. Figure 3 yes Figure 2 The diagram shows the disassembled structure of the cabin longitudinal beams. Figure 4 yes Figure 3 The diagram shows the structure of the first reinforcing member. Figure 5 yes Figure 3 The diagram shows the structure of the second reinforcing member.

[0037] The front bulkhead assembly 10 includes a lower front bulkhead crossbeam 200, a nacelle longitudinal beam 100, and a reinforcing assembly 300. One end of the nacelle longitudinal beam 100 is connected to the lower front bulkhead crossbeam 200. The nacelle longitudinal beam 100 includes an inner longitudinal beam plate 110 and an outer longitudinal beam plate 120. The inner longitudinal beam plate 110 and the outer longitudinal beam plate 120 form a receiving cavity 130 extending in a first direction. The reinforcing assembly 300 is disposed at one end of the receiving cavity 130 near the lower front bulkhead crossbeam 200. The reinforcing assembly 300 includes a first reinforcing member 310 and a second reinforcing member 320. The first reinforcing member 310 includes a first support plate 311, and the second reinforcing member 320 includes a second support plate 321. Both the first support plate 311 and the second support plate 321 are supported between the inner longitudinal beam plate 110 and the outer longitudinal beam plate 120. The second support plate 321 extends in the first direction, and the first support plate 311 extends in a second direction intersecting the first direction.

[0038] The two ends of the lower front crossbeam 200 are used to connect to the sill beams, so that when the lower front crossbeam 200 is subjected to external force, the force can be transmitted to the sill beams. The front end of the lower front crossbeam 200 is also connected to the engine compartment longitudinal beams 100. There are two engine compartment longitudinal beams 100, which are spaced apart in the lateral direction. Thus, the engine compartment longitudinal beams 100 can transmit the impact force to the lower front crossbeam 200, and then transmit the impact force to the vehicle body through the connection between the lower front crossbeam 200 and the sill beams, thereby improving the vehicle's impact performance. Specifically, the lower front crossbeam 200 may include a lateral main body and oblique transmission parts connected to both ends of the main body. The lateral main body extends in the lateral direction, which can be understood as the width direction of the vehicle body. The oblique transmission parts extend in the longitudinal direction toward the lower front crossbeam 200, and also extend in the lateral direction away from the other engine compartment longitudinal beam 100. In other words, the oblique transmission section extends obliquely within the plane of the vehicle body, making it easier to transmit the impact force from the engine compartment longitudinal beam 100 to the door sill beams on both sides when the lower front crossbeam 200 is subjected to impact force from the engine compartment longitudinal beam 100, thereby improving the vehicle's impact performance. Furthermore, a mounting plate is provided at the connection between the transverse main body and the oblique transmission section. The mounting plate has a mounting groove, and one end of the engine compartment longitudinal beam 100 near the lower front crossbeam 200 is inserted into the mounting groove. The portion of the engine compartment longitudinal beam 100 is fixedly connected to the mounting plate to increase the connection strength between the engine compartment longitudinal beam 100 and the lower front crossbeam 200, thereby improving the vehicle's impact performance.

[0039] The cabin longitudinal beam 100 includes an inner longitudinal beam plate 110 and an outer longitudinal beam plate 120. Both the inner and outer longitudinal beam plates 110 and 120 extend in a first direction. The inner and outer longitudinal beam plates 110 and 120 form accommodating cavities 130 extending in the first direction, which reduces weight and improves the structural strength of the cabin longitudinal beam 100. The first direction can be understood as the aforementioned longitudinal direction. Specifically, a mounting plate can be simultaneously connected to the inner and outer longitudinal beam plates 110 and 120, thereby improving the connection strength between the cabin longitudinal beam 100 and the front lower crossbeam 200. In some embodiments, the inner longitudinal beam plate 110 may include an inner plate main body plate, inner plate side plates connected to both ends of the inner plate main body in a second direction, and a side plate connecting edge 322 connected to the end of the inner plate side plate away from the inner plate main body. The inner plate side plate extends toward the longitudinal beam outer plate 120, and the side plate connecting edge 322 is opposite to the longitudinal beam outer plate 120, so that the longitudinal beam inner plate 110 is connected to the longitudinal beam outer plate 120 through the side plate connecting edge 322, thereby forming a receiving cavity 130 extending in the first direction.

[0040] The reinforcing assembly 300 includes a first reinforcing member 310 and a second reinforcing member 320. Both the first reinforcing member 310 and the second reinforcing member 320 are located within the accommodating cavity 130, and are positioned at the end of the accommodating cavity 130 near the lower front crossbeam 200. Specifically, at least a portion of the first reinforcing member 310 and the second reinforcing member 320 corresponds to a mounting groove, meaning at least a portion of the reinforcing assembly 300 is located within the mounting groove, thereby improving the structural strength of the end of the engine compartment longitudinal beam 100 near the lower front crossbeam 200 and further enhancing the vehicle's impact performance. The first reinforcing member 310 includes a first support plate 311, and the second reinforcing member 320 includes a second support plate 321. Both the first support plate 311 and the second support plate 321 are supported between the inner longitudinal beam plate 110 and the outer longitudinal beam plate 120. The second support plate 321 extends in a first direction and extends in a second direction, intersecting the first direction. That is to say, the planes on which the first support plate 311 and the second support plate 321 are located respectively form an angle with the inner plate 110 and the outer plate 120 of the longitudinal beam, and the plane on which the first support plate 311 is located is not parallel to the plane on which the second support plate 321 is located. For example, the first support plate 311 and the second support plate 321 may be perpendicular to each other. For another example, the two planes on which the first support plate 311 and the second support plate 321 are located intersect but are not perpendicular; that is, the projection of the first support plate 311 onto the plane on which the second support plate 321 is located partially overlaps with the first support plate 311 in the first direction, and partially lies at the end of the second support plate 321 away from the lower front crossbeam 200.

[0041] Furthermore, both the first support plate 311 and the second support plate 321 can be perpendicularly arranged to the inner plate 110 and the outer plate 120 of the longitudinal beam. That is, the planes on which the first support plate 311 and the second support plate 321 are respectively located are approximately perpendicular to the inner plate 110 and the outer plate 120 of the longitudinal beam, so that the first support plate 311 and the second support plate 321 can be more stably supported between the inner plate 110 and the outer plate 120 of the longitudinal beam. In addition, the first support plate 311 can be spaced apart from the lower front crossbeam 200 in the first direction, and the second support plate 321 is located between the first support plate 311 and the lower front crossbeam 200, which can further improve the structural strength of the end of the cabin longitudinal beam 100 near the lower front crossbeam 200. One end of the second support plate 321 can also be connected to the side of the first support plate 311 near the second support plate 321, thereby further improving the structural strength of the reinforcing assembly 300.

[0042] Through the above-described embodiments, the reinforcing component 300 is located inside the engine compartment longitudinal beam 100, and the first support plate 311 and the second support plate 321 extend in the second direction and the first direction, respectively. This allows the reinforcing component 300 to not only not encroach on the external assembly space, but also to improve the structural strength of the engine compartment longitudinal beam 100 in different directions, thereby enhancing the collision performance of the entire vehicle.

[0043] In some embodiments, the first reinforcing member 310 includes a first connecting plate 312, which is connected to one end of the first support plate 311 near the inner plate 110 of the longitudinal beam. The first connecting plate 312 is disposed opposite to the inner plate 110 of the longitudinal beam, and the first support plate 311 is supported between the inner plate 110 and the outer plate 120 of the longitudinal beam by the first connecting plate 312. The first connecting plate 312 is connected to one end of the first support plate 311 near the inner plate 110 of the longitudinal beam. It can be understood that the first connecting plate 312 is formed by bending and extending the end of the first support plate 311 near the inner plate 110 of the longitudinal beam in a first direction, and the first connecting plate 312 is disposed opposite to the inner plate 110 of the longitudinal beam. This can improve the structural strength of the first support plate 311 and increase the contact area of ​​the first support plate 311 on one side of the inner plate 110 of the longitudinal beam by the first connecting plate 312, thereby improving the stability of the first support plate 311 and thus improving the impact performance of the cabin longitudinal beam 100.

[0044] In some embodiments, the first connecting plate 312 is provided with a first reinforcing groove 3121, which is located in the middle of the first connecting plate 312 and is recessed away from the inner plate 110 of the longitudinal beam. The first reinforcing groove 3121, located in the middle of the first connecting plate 312 and recessed away from the inner plate 110 of the longitudinal beam, creates a structure in the first connecting plate 312 that is recessed in the middle and protruding on both sides. This forms a small cavity between the first connecting plate 312 and the inner plate 110 of the longitudinal beam to absorb impact forces, thereby improving the structural strength of the first connecting plate 312. Furthermore, the position of the first support plate 311 corresponding to the first reinforcing groove 3121 can be recessed accordingly, so that the first connecting plate 312 and the first support plate 311 together form the first reinforcing groove 3121. Therefore, by providing the first reinforcing groove 3121, the structural strength of both the first support plate 311 and the first connecting plate 312 can be improved simultaneously, thereby improving the vehicle's impact performance.

[0045] See Figure 6 , Figure 6 yes Figure 3 The diagram shows the structure of the inner reinforcement plate.

[0046] In some embodiments, the cabin longitudinal beam 100 includes an inner plate reinforcing plate 140, which is disposed on the side of the inner plate 110 of the longitudinal beam near the reinforcing assembly 300. A first connecting plate 312 is connected to the inner plate reinforcing plate 140. The inner plate reinforcing plate 140 includes a second reinforcing groove 141 extending along a first direction. The second reinforcing groove 141 is recessed towards the reinforcing assembly 300, and its bottom wall is connected to the bottom wall of the first reinforcing groove 3121. The inner plate reinforcing plate 140 is provided on the side of the inner plate 110 near the reinforcing assembly 300, and it also extends along the first direction. The inner plate reinforcing plate 140 is disposed opposite to the inner plate 110 of the longitudinal beam and is fixedly connected to it, thereby improving the structural strength of the inner plate 110 of the longitudinal beam. Furthermore, the inner plate reinforcing plate 140, the end of the longitudinal beam inner plate 110 near the lower front crossbeam 200, and the mounting plate can be connected by bolts. Adding an inner plate reinforcing plate 140 to the longitudinal beam inner plate 110 can reduce the risk of bolt breakage. The longitudinal beam inner plate 110 is also provided with a second reinforcing groove 141 at least in part. The second reinforcing groove 141 extends along the first direction, which can improve the structural strength of the inner plate reinforcing plate 140. The inner panel reinforcing plate 140 is connected to the first connecting plate 312 of the reinforcing assembly 300, and the second reinforcing groove 141 is correspondingly provided with the first reinforcing groove 3121, so that the corresponding part of the second reinforcing groove 141 and the first reinforcing groove 3121 is located in the first reinforcing groove 3121, and the bottom wall of the second reinforcing groove 141 is connected with the bottom wall of the first reinforcing groove 3121, so that the reinforcing assembly 300 is supported between the longitudinal beam outer plate 120 and the inner panel reinforcing plate 140 through the first support plate 311 and the first connecting plate 312, and the first reinforcing groove 3121 of the first connecting plate 312 is correspondingly connected with the second reinforcing groove 141 of the inner panel reinforcing plate 140, thereby further improving the structural strength of the end of the engine compartment longitudinal beam 100 near the front lower crossbeam 200 and improving the vehicle's impact performance. Furthermore, the dimension of the first reinforcing groove 3121 in the second direction can be larger than the dimension of the second reinforcing groove 141 in the second direction, so that the outer wall of the second reinforcing groove 141 near the first connecting plate 312 forms a gap with the inner wall of the first reinforcing groove 3121 in the third direction, thereby forming a small cavity for absorbing impact force between the first reinforcing groove 3121 and the second reinforcing groove 141, thereby improving the structural strength of the connection between the first reinforcing member 310 and the inner plate reinforcing plate 140, so that the inner plate reinforcing plate 140 and the first connecting plate 312 can cooperate with each other to improve the vehicle's impact performance.

[0047] See Figure 7 , Figure 7 yes Figure 2 The diagram shows a sectional view of the cabin longitudinal beams along the AA direction.

[0048] In some embodiments, the first support plate 311 includes a second connecting plate 313, the second connecting plate 313 includes a connecting body portion 3131, the connecting body portion 3131 is connected to one end of the first support plate 311 away from the inner plate 110 of the longitudinal beam, the connecting body portion 3131 is disposed opposite to the outer plate 120 of the longitudinal beam, and the two opposite sides of the connecting body portion 3131 are respectively connected to the second reinforcing member 320 and the outer plate 120 of the longitudinal beam.

[0049] The second connecting plate 313 includes a connecting main body 3131, which is connected to the end of the first support plate 311 away from the inner plate 110 of the longitudinal beam. The connecting main body 3131 extends in a first direction toward the first support plate 311 and toward the second support plate 321, so that it is positioned opposite to and fixedly connected to the outer plate 120 of the longitudinal beam. This improves the structural strength of the reinforcing component 300 and increases the connection area between the reinforcing component 300 and the outer plate 120 of the longitudinal beam, thus enhancing the stability of the reinforcing component 300 when supported between the inner plate 110 and the outer plate 120 of the longitudinal beam. Furthermore, the side of the connecting main body 3131 away from the outer plate 120 of the longitudinal beam is also connected to the second support plate 321, so that the two adjacent ends of the second reinforcing member 320 are respectively connected to the first support plate 311 and the second connecting plate 313 of the first reinforcing member 310, further improving the structural strength of the reinforcing component 300.

[0050] In some embodiments, the second connecting plate 313 includes an edge connecting portion 3132, which is connected to both ends of the connecting body portion 3131 in a second direction. The cabin longitudinal beam 100 includes an inner plate reinforcing plate 140, which is disposed on the side of the inner plate 110 of the longitudinal beam near the reinforcing component 300. At least one end of the inner plate reinforcing plate 140 in the second direction is provided with an edge receiving portion 142, which extends toward the outer plate 120 of the longitudinal beam. The edge connecting portion 3132 is connected to the corresponding edge receiving portion 142. The inner plate reinforcing plate 140 also includes an edge receiving portion 142, which is disposed at at least one end of the inner plate reinforcing plate 140 in the second direction. The edge receiving portion 142 extends in the first direction and extends toward the longitudinal beam outer plate 120 to improve the structural strength of the inner plate reinforcing plate 140. The edge receiving portion 142 of the inner plate reinforcing plate 140 is disposed opposite to and connected to the inner plate side plate of the longitudinal beam inner plate 110, thereby further improving the structural strength of the longitudinal beam inner plate 110. In addition, the second connecting plate 313 also includes an edge connecting portion 3132, which is connected to both ends of the connecting body portion 3131 in the second direction and is disposed opposite to the inner plate side plate of the longitudinal beam inner plate 110, so that the edge connecting portion 3132 of the second connecting plate 313 can be connected to the inner plate side plate or the edge receiving portion 142 separately or simultaneously. This can further improve the connection strength between the reinforcing component 300 and the inner panel reinforcing plate 140 and the longitudinal beam inner plate 110, thereby improving the structural strength of the cabin longitudinal beam 100. As an example, the inner panel reinforcing plate 140 has an edge receiving portion 142 at one end in the second direction. For example, the edge receiving portion 142 is located at the upper or lower end of the inner panel reinforcing plate 140 in the second direction, and the edge receiving portion is not connected to the corresponding inner panel side plate. The edge connecting portions 3132 at both ends of the second connecting plate 313 are respectively connected to the edge receiving portion 142 at one end and the opposite inner panel side. As another example, the inner panel reinforcing plate 140 has edge receiving portions 142 at both ends in the second direction, and the edge receiving portions 142 at both ends are respectively connected to the corresponding inner panel side. The edge connecting portions 3132 at both ends of the second connecting plate 313 are respectively connected to a corresponding edge receiving portion 142.

[0051] In some embodiments, the second reinforcing member 320 includes a connecting edge 322, which is disposed around the periphery of the second support plate 321. Different sides of the connecting edge 322 are respectively disposed opposite to the corresponding connecting body part 3131, the inner plate reinforcing plate 140 and the first support plate 311, and are connected to each other.

[0052] The connecting edge 322 is arranged around the periphery of the second support plate 321, thereby improving the structural strength of the first support plate 311. Different sides of the connecting edge 322 are respectively arranged opposite to the connecting body 3131 of the corresponding second connecting plate 313, the first support plate 311, and the inner plate side plate, and are interconnected. This improves the connection strength between the second reinforcing member 320 and the first reinforcing member 310 and the inner plate reinforcing plate 140, and improves the overall structural strength of the cabin longitudinal beam 100. In addition, the connecting edge 322 may have a notch at the corner, so that the connecting edge 322 forms multiple connecting segments spaced around the periphery of the second support plate 321. The multiple connecting segments have a higher degree of freedom and can reduce the risk of fracture at the corner of the connecting edge 322 due to metal fatigue.

[0053] See Figure 8 , Figure 8 yes Figure 3 The diagram shows the structural schematic of the outer plate of the longitudinal beam.

[0054] In some embodiments, the outer longitudinal beam plate 120 is located outside the front bulkhead assembly 10. The outer longitudinal beam plate 120 includes an extension connection portion 121, which is located at one end of the outer longitudinal beam plate 120 near the lower front bulkhead crossbeam 200. The extension connection portion 121 is bent and extends in a first direction toward the lower front bulkhead crossbeam 200 and away from the inner longitudinal beam plate 110, and is fixedly connected to the lower front bulkhead crossbeam 200. The outer longitudinal beam plate 120 being located outside the front bulkhead assembly 10 can be understood as the outer longitudinal beam plate 120 being located on the side of the longitudinal beam 100 in its respective cabin away from another cabin longitudinal beam 100. The extension connection portion 121 of the outer longitudinal beam plate 120 is located at one end of the outer longitudinal beam plate 120 near the lower front bulkhead crossbeam 200. The extension connection portion 121 is bent and extends in a first direction toward the lower front bulkhead crossbeam 200 and away from the inner longitudinal beam plate 110, and is fixedly connected to the lower front bulkhead crossbeam 200. Specifically, the extension connection 121 can be disposed opposite to the oblique transmission portion of the lower front crossbeam 200 and fixedly connected to the oblique transmission portion. That is to say, the extension connection 121, like the oblique transmission portion, extends obliquely, so that the engine compartment longitudinal beam 100 can transmit the impact force obliquely to the lower front crossbeam 200 through the extension connection 121, and then transmit the impact force to the sill beam through the lower front crossbeam 200. In this way, the force transmission path of the engine compartment longitudinal beam 100 and the lower front crossbeam 200 can be optimized, so that the engine compartment longitudinal beam 100 can more effectively transmit the impact force to the sill beam, further improving the vehicle's impact performance.

[0055] In some embodiments, a reinforcing rib 1211 is provided at the bending crease of the extension connection portion 121, and the reinforcing rib 1211 extends along the bending crease. The presence of a reinforcing rib 1211 at the bending crease of the extension connection portion 121, and the reinforcing rib 1211 being provided along the extension direction of the crease, can improve the structural strength of the extension connection portion 121 of the longitudinal beam outer plate 120 and improve the vehicle's impact performance.

[0056] In summary, the reinforcing component 300 is located inside the engine compartment longitudinal beam 100, and the first support plate 311 and the second support plate 321 extend in the second direction and the first direction, respectively. This ensures that the reinforcing component 300 does not encroach on the external assembly space, and can also improve the structural strength of the engine compartment longitudinal beam 100 in different directions, thereby enhancing the collision performance of the entire vehicle.
