[0041] The front body structure 100 according to an embodiment of the present utility model will be described below with reference to the drawings.

[0042] As Figure 3 and Figure 4 shown, the front body structure 100 according to an embodiment of the present utility model is for a vehicle and includes a floor 1, a bulkhead 2, a first reinforcing cross member 4, and a second reinforcing cross member 5.

[0043] Specifically, referring to the attached Figure 3 drawings, the bulkhead 2 is connected to the front end of the floor 1 and extends along the left - right direction of the vehicle (as Figure 3 shown), and is used to separate the engine compartment from the passenger compartment, preventing exhaust gas, high temperature, and noise in the engine compartment from entering the passenger compartment, thereby protecting the safety of the passenger compartment and passengers. When the vehicle collides, the bulkhead 2 can play a protective role for the passenger compartment and protect the safety of the driver and passengers.

[0044] Furthermore, referring to the attached Figure 3 and the attached Figure 4 drawings, and in combination with referring to the attached Figure 5 drawings, the first reinforcing cross member 4 is disposed below the bulkhead 2. The first reinforcing cross member 4 extends along the left - right direction and is connected to the inner sill panel 9 of the vehicle. The upper end of the first reinforcing cross member 4 is connected to both the bulkhead 2 and the floor 1. The setting of the first reinforcing cross member 4 can strengthen the bulkhead 2, optimize the front body structure 100, form a continuous force - transmission channel, effectively disperse the collision energy received by the front part of the vehicle body, reduce the intrusion into the passenger compartment, and protect the safety of the driver and passengers.

[0045] Even further, referring to the attached Figure 4 drawings, the lower surface of the first reinforcing cross member 4 is lower than the lower surface of the floor 1. The floor 1, the first reinforcing cross member 4, and the inner sill panel 9 can jointly define an installation space. The battery pack of the vehicle is disposed below the floor 1 and behind the first reinforcing cross member 4. The battery pack is located within the installation space. The first reinforcing cross member 4 can protect the battery pack from the front side, avoid the battery pack from being knocked, ensure the safety of the battery pack, and thus improve safety and reliability.

[0046] Preferably, as Figure 4As shown, the lower surface of the first reinforcing crossbeam 4 is lower than the lower surface of the battery pack, which can protect the battery pack from longitudinal extrusion. Along the up and down direction (as Figure 4 shown), the distance between the lower surface of the first reinforcing crossbeam 4 and the lower surface of the battery pack is a, and it satisfies: a ≥ 10 mm. It can not only protect the battery pack from longitudinal extrusion but also play a protective role to avoid the battery pack from being knocked. For example, the distance a between the lower surface of the first reinforcing crossbeam 4 and the lower surface of the battery pack can be 10 mm, 11 mm, 12 mm, 13 mm, 14 mm or 15 mm.

[0047] Furthermore, referring to Figure 3 and Figure 4 shown, in combination with referring to Figure 6 , the second reinforcing crossbeam 5 is located on the front side of the front bulkhead 2 and extends along the left and right direction. The second reinforcing crossbeam 5 is connected to the front bulkhead 2. The setting of the second reinforcing crossbeam 5 can further strengthen the front bulkhead 2, optimize the front body structure 100, form a continuous force transmission channel, effectively disperse the collision energy received by the front of the vehicle body, reduce the intrusion of the occupant compartment, and protect the safety of the driver and passengers.

[0048] It should be noted that welding connection or bolt connection can be selected between the various components of the front body structure 100. Specifically, the welding can be spot welding or CO 2 (carbon dioxide) gas shielded welding. Welding connection has low cost, high production efficiency, and convenient operation, which can facilitate the production and processing of the front body structure 100 and reduce the production and processing cost of the front body structure 100. While the bolt connection has a simple structure, good adjustability, and high reliability, which can facilitate the assembly and disassembly of the front body structure 100 and reduce the production difficulty and maintenance difficulty of the front body structure 100.

[0049] Furthermore, referring to Figure 3 shown, the front body structure 100 further includes two A-pillar inner panels 8, which are respectively arranged at both ends of the front bulkhead 2 along the left and right direction. Both ends of the first reinforcing crossbeam 4 in the length direction (the left and right direction shown in Figure 3 shown) are respectively connected to the two A-pillar inner panels 8 to form a transverse force transmission channel. When the vehicle has a frontal collision, the collision energy received by the first reinforcing crossbeam 4 can be dispersed to the two A-pillar inner panels 8, reducing the intrusion into the occupant compartment and protecting the safety of the driver and passengers. It should be noted that the connection between the first reinforcing crossbeam 4 and the A-pillar inner panel 8 is a closed cavity structure, with high connection strength, which can avoid the tearing of the welding points when the vehicle collides and improve the collision safety performance of the vehicle.

[0050] According to the front body structure 100 of the embodiment of the present utility model, by respectively providing a first reinforcing cross beam 4 and a second reinforcing cross beam 5 on the lower side and the front side of the front bulkhead 2, the front bulkhead 2 can be strengthened, the front body structure 100 can be optimized, a through force transmission channel can be formed, the collision energy received by the front of the vehicle can be effectively dispersed, the intrusion into the occupant compartment can be reduced, and the safety of the driver and passengers can be protected. Moreover, since the lower surface of the first reinforcing cross beam 4 is lower than the lower surface of the floor 1, and the battery pack of the vehicle is provided on the lower side of the floor 1 and behind the first reinforcing cross beam 4, the first reinforcing cross beam 4 can protect the battery pack from the front side, avoid the battery pack from being knocked, ensure the safety of the battery pack, and thus improve the safety and reliability.

[0051] In some embodiments of the present utility model, referring to the attached Figure 4 and the attached Figure 5 As shown, the first reinforcing cross beam 4 includes a bottom plate 42, a first connecting plate 43 and a second connecting plate 44. The bottom plate 42 is horizontally arranged and extends in the left-right direction, and the bottom plate 42 is located on the lower side of the floor 1. The first connecting plate 43 and the second connecting plate 44 are both vertically arranged. The lower end of the first connecting plate 43 and the lower end of the second connecting plate 44 are respectively connected to both ends of the bottom plate 42 in the front-rear direction (as Figure 4 shown). The upper end of the first connecting plate 43 is connected to the front bulkhead 2, and the upper end of the second connecting plate 44 is connected to the floor 1. In the cross-section perpendicular to the left-right direction of the vehicle, the bottom plate 42, the first connecting plate 43 and the second connecting plate 44 together form a "U"-shaped first reinforcing cross beam 4, so that the first reinforcing cross beam 4 and the front bulkhead 2 jointly define a cavity 40. The existence of the cavity 40 can further protect the battery pack, absorb the collision energy, avoid the battery pack from being knocked, ensure the safety of the battery pack, improve the collision safety performance of the vehicle, and protect the safety of the driver and passengers.

[0052] In some embodiments of the present utility model, referring to the attached Figure 3 and the attached Figure 4 As shown, the front bulkhead 2 includes a first plate 21 and a second plate 22. The first plate 21 is generally vertically arranged. The lower end of the first plate 21 is connected to the upper end of the second plate 22. In the front-to-back direction (as Figure 4As shown in the figure, the second plate 22 slopes downward. The upper ends of the first connecting plate 43 and the second connecting plate 44 are respectively connected to both ends of the second plate 22, so that a cavity 40 is defined between the first reinforcing cross beam 4 and the second plate 22. The setting of the first reinforcing cross beam 4 can focus on protecting the lower side of the front bulkhead 2, improve the structural strength of the lower side of the front bulkhead 2, transfer and absorb the collision force received by the front bulkhead 2, improve the collision safety performance of the front part structure 100 of the vehicle body, and protect the safety of the driver and passengers. It should be noted that the first plate 21 is generally vertically arranged. It can be that the first plate 21 is completely vertical and strictly extends in the up and down direction; it can also be that the first plate 21 has a certain angle with the up and down direction, and no limitation is made here. Optionally, the first plate 21 and the second plate 22 can be separate parts, which is convenient for the production and processing of the front bulkhead 2. The first plate 21 and the second plate 22 can also be integrally formed by laser welding, which is convenient for the assembly of the front bulkhead 2 and simplifies the assembly process of the front part structure 100 of the vehicle body.

[0053] In some embodiments of the present invention, referring to the attached Figure 3 , the attached Figure 4 and the attached Figure 6 As shown, the second reinforcing cross beam 5 and the front bulkhead 2 jointly define a second cavity 50. The existence of the second cavity 50 can absorb collision energy, which is beneficial to improving the collision safety performance of the vehicle and protecting the safety of the driver and passengers. Along the left and right direction, the height of the second reinforcing cross beam 5 remains unchanged in the up and down direction. It can be understood that in the prior art, the front part structure of the vehicle body usually has a middle channel, and the existence of the middle channel often interferes with the second reinforcing cross beam, resulting in the lower surface of the second reinforcing cross beam needing to be recessed upward to avoid the middle channel, thus affecting the coherence of the second cavity. However, the front part structure 100 of the vehicle body of the present invention adopts a design without a middle channel, canceling the middle channel in the prior art. The second reinforcing cross beam 5 does not need to avoid the middle channel, so that the height of the second cavity 50 remains unchanged in the up and down direction, further ensuring the force transmission path of the second reinforcing cross beam 5 and improving the force transmission efficiency of the second reinforcing cross beam 5.

[0054] Further, referring to the attached Figure 2 and the attached Figure 3 As shown, both ends of the second reinforcing cross beam 5 in the length direction (the left and right direction shown in the attached Figure 2 figure) are respectively connected to two inner A-pillar plates 8, forming a transverse force transmission channel. When the vehicle undergoes a frontal collision, the collision energy received by the second reinforcing cross beam 5 can be dispersed to the two inner A-pillar plates 8, reducing the intrusion into the passenger compartment and protecting the safety of the driver and passengers. It should be noted that the connection between the second reinforcing cross beam 5 and the inner A-pillar plate 8 is a closed cavity structure with high connection strength, which can avoid the tearing of the welding points when the vehicle collides and improve the collision safety performance of the vehicle.

[0055] In some embodiments of the present invention, referring to the attachedFigure 1 , attached Figure 2 and attached Figure 3 As shown, the front body structure 100 further includes a first longitudinal beam 3, and the first longitudinal beam 3 extends in the front-rear direction (as Figure 1 shown). The rear end of the first longitudinal beam 3 is connected to both the front bulkhead 2 and the first reinforcing cross beam 4. In the front-rear direction, the second reinforcing cross beam 5 is located between the first longitudinal beam 3 and the front bulkhead 2. The setting of the first longitudinal beam 3 can be used to carry and support the vehicle body, so that the width of the front and rear of the frame remains stable. When the vehicle encounters a collision, the first longitudinal beam 3 absorbs the collision energy through crushing deformation and bending deformation to ensure the safety of the driver and passengers. Further, referring to attached Figure 1 and attached Figure 3 shown, the first longitudinal beam 3 includes an inner longitudinal beam plate 31 and an outer longitudinal beam plate 32. The inner longitudinal beam plate 31 and the outer longitudinal beam plate 32 are arranged and connected in the left-right direction of the vehicle, which is convenient for the production and processing of the first longitudinal beam 3.

[0056] In a further embodiment of the present utility model, referring to attached Figure 4 shown, in the front-to-rear direction (as Figure 4 shown), the height of the rear end of the first longitudinal beam 3 gradually increases in the up-down direction (as Figure 4 shown), so that the rear end of the first longitudinal beam 3 is directly connected to the front bulkhead 2 and the first reinforcing cross beam 4, which can relatively reduce the number of components of the front body structure 100, simplify the front body structure 100, reduce the connection complexity of the front body structure 100, improve the force transmission efficiency of the front body structure 100, and improve the stability and reliability of the front body structure 100.

[0057] In some embodiments of the present utility model, referring to attached Figure 3 and attached Figure 4 shown, the front body structure 100 further includes a second longitudinal beam 6. The second longitudinal beam 6 is disposed above the floor 1 and extends in the front-rear direction (as Figure 3 shown). The front end of the second longitudinal beam 6 is connected to the front bulkhead 2. The second longitudinal beam 6 and the first longitudinal beam 3 are respectively located on both sides of the front bulkhead 2 in the front-rear direction. The second longitudinal beam 6 and the first longitudinal beam 3 are arranged oppositely in the front-rear direction, so that a longitudinal force transmission channel can be formed. When the vehicle undergoes a frontal collision, the collision energy is transmitted from the first longitudinal beam 3 to the second longitudinal beam 6, reducing the intrusion of the passenger compartment and protecting the safety of the driver and passengers.

[0058] In a further embodiment of the present utility model, referring to attached Figure 1 and attached Figure 2As shown, there are multiple first longitudinal beams 3, and the multiple first longitudinal beams 3 are spaced apart in the left - right direction. There are multiple second longitudinal beams 6 corresponding one - to - one to the multiple first longitudinal beams 3, which can further improve the structural strength of the front - end structure 100 of the vehicle body, increase the force - transmission paths of the front - end structure 100 of the vehicle body, further disperse the collision energy received by the vehicle, reduce the intrusion into the passenger compartment, and protect the safety of the driver and passengers. In a specific example, refer to the attached Figure 1 and the attached Figure 2 As shown, there are two first longitudinal beams 3 spaced in the left - right direction, and there are two second longitudinal beams 6 corresponding one - to - one to the two first longitudinal beams 3.

[0059] In a further embodiment of the present utility model, refer to the attached Figure 3 As shown, the front - end structure 100 of the vehicle body further includes a front cross - beam 7. The front cross - beam 7 is disposed above the floor 1 and connected to the floor 1. The front cross - beam 7 is located at the front end of the front row seats of the vehicle. The rear end of the second longitudinal beam 6 is connected to the front cross - beam 7. The front cross - beam 7 and the front panel 2 are spaced apart in the front - rear direction. The collision force transmitted from the first longitudinal beam 3 to the second longitudinal beam 6 can be transmitted to the front cross - beam 7, improving the longitudinal force - transmission channel. When the vehicle undergoes a frontal collision, it can disperse the collision energy, reduce the intrusion into the passenger compartment, and protect the safety of the driver and passengers.

[0060] Further, refer to the attached Figure 1 、the attached Figure 2 and the attached Figure 3 As shown, the front - end structure 100 of the vehicle body further includes an inner sill panel 9. The inner sill panel 9 extends in the front - rear direction and there are two of them. The two inner sill panels 9 are respectively located at both ends of the floor 1 in the left - right direction. The front ends of the inner sill panels 9 are both connected to the first reinforcing cross - beam 4 and the inner A - pillar panel 8. The two ends of the front cross - beam 7 in the length direction (the left - right direction shown in the attached Figure 1 figure) are respectively connected to the two inner sill panels 9, so that the first force - transmission path, the second force - transmission path and the third force - transmission path can be realized. Among them, the first force - transmission path is from the first longitudinal beam 3 to the first reinforcing cross - beam 4, and then from the first reinforcing cross - beam 4 to the inner sill panel 9. The second force - transmission path is from the first longitudinal beam 3 through the front panel 2 to the second longitudinal beam 6, and then from the second longitudinal beam 6 through the front cross - beam 7 to the inner sill panel 9. The third force - transmission path is from the first longitudinal beam 3 to the second reinforcing cross - beam 5, and then from the second reinforcing cross - beam 5 through the inner A - pillar panel 8 to the inner sill panel 9. It can realize multiple force - transmission paths of the front - end structure 100 of the vehicle body, disperse the collision energy received by the front - end structure 100 of the vehicle body, improve the structural strength of the front - end structure 100 of the vehicle body, improve the stability and reliability of the front - end structure 100 of the vehicle body, reduce the intrusion into the passenger compartment, and protect the safety of the driver and passengers.

[0061] In some embodiments of the present utility model, refer to the attached Figure 3As shown, the first reinforcing crossbeam 4 and the front bulkhead 2 jointly define a cavity 40. The existence of the cavity 40 can absorb collision energy, which is beneficial to improving the collision safety performance of the vehicle and protecting the safety of the driver and passengers. A reinforcing plate 41 is provided in the cavity 40. The reinforcing plate 41 is connected to the front bulkhead 2. Along the front-rear direction of the vehicle, the reinforcing plate 41 and the first longitudinal beam 3 are arranged oppositely. The first longitudinal beam 3, the reinforcing plate 41, and the second longitudinal beam 6 are arranged in sequence, and can form a stable longitudinal force transmission channel. When a frontal collision occurs to the vehicle, the collision energy is transmitted through the first longitudinal beam 3, the reinforcing plate 41, and the second longitudinal beam 6 to the front crossbeam 7 in sequence, and then transmitted from the front crossbeam 7 to the inner panel 9 of the sill, forming a complete force transmission channel, further reducing the intrusion of the occupant compartment and protecting the safety of the driver and passengers.

[0062] It should be noted that the front body structure 100 of the present utility model adopts a design without a middle channel, canceling the middle channel in the prior art, which can reduce the space occupied by the front body structure 100 in the left-right direction and the up-down direction (such as Figure 3 shown), which is beneficial to the human-machine and styling design of the vehicle. For example, when there is no middle console design in the middle, the leg space of the driver and passengers can be increased, and the lateral passing performance can be improved. When there is a middle console design in the middle, it has a certain storage space, which can improve the storage and collection performance of the vehicle. And the middle console can be designed to be movable along the front-rear direction, improving the functionality of the middle console and enhancing the product competitiveness.

[0063] The present utility model also proposes a vehicle having the front body structure 100 of the above embodiment.

[0064] For the vehicle according to the embodiment of the present utility model, by providing the above front body structure 100, and by providing a first reinforcing crossbeam 4 and a second reinforcing crossbeam 5 on the lower side and the front side of the front bulkhead 2 respectively, the front bulkhead 2 can be strengthened, the front body structure 100 can be optimized, a through force transmission channel can be formed, the collision energy received by the front part of the body can be effectively dispersed, the intrusion of the occupant compartment can be reduced, and the safety of the driver and passengers can be protected. And, since the lower surface of the first reinforcing crossbeam 4 is lower than the lower surface of the floor 1, and the battery pack of the vehicle is provided on the lower side of the floor 1 and behind the first reinforcing crossbeam 4, the first reinforcing crossbeam 4 can protect the battery pack from the front side, avoiding the battery pack from being knocked and ensuring the safety of the battery pack, thereby improving the safety and reliability.
