[0002] With the development of the national economy and the continuous improvement of people's living standards, vehicles are becoming increasingly important in daily life. The NVH performance and safety of vehicles during operation are key considerations during vehicle manufacturing.

Furthermore, in the event of a collision, the front engine compartment is often the primary force bearing point.

[0040] like Figures 1-6 As shown, a front cabin assembly according to one embodiment of the present invention includes a cabin top assembly 1 , a middle frame assembly 2 and a bottom sub-frame assembly 3 .

[0041] The rear part of the cabin top assembly 1 is connected to the front panel structure 4 and forms a cabin top ring structure, the middle frame assembly 2 is located below the cabin top assembly 1, the rear part of the middle frame assembly 2 is connected to the front panel structure 4 and forms a middle frame ring structure, the bottom sub-frame assembly 3 is located below the middle frame assembly 2, and the rear part of the bottom sub-frame assembly 3 is connected to the front panel structure 4 and forms a bottom sub-frame ring structure.

[0042] Among them, the front engine compartment assembly is arranged at the front of the vehicle. The engine, suspension system, cooling system, electrical lines and pipelines can all be installed in the front engine compartment assembly to support and protect the structure required for vehicle operation. When the front of the vehicle is hit by a collision, the front engine compartment assembly can absorb the collision force to protect the passenger compartment and improve driving safety.

[0043] Specifically, the front cabin assembly is provided with a cabin top component 1, a middle frame component 2 and a bottom sub-frame component 3. The cabin top component 1 is arranged at the top of the front cabin assembly and can be used to provide support for the cabin cover and the like of the front cabin assembly, and the front headlights and other structures of the vehicle can also be installed on the cabin top component 1. The cabin top component 1 is constructed as a "U"-shaped structure open to the rear and the rear part of the cabin top component 1 is connected to the front wall structure 4, so that the cabin top component 1 and the front wall structure 4 can jointly form a cabin top ring structure. When the front or side of the top of the front cabin assembly is subjected to a collision force, the collision force can be transmitted backward along the cabin top component 1 to the front wall structure 4, and the cabin top component 1 is constructed as a cabin top ring structure, so that the collision force can be dispersed and transmitted to weaken the effect of the collision force.

[0044] The middle frame assembly 2 is arranged in the middle of the front cabin assembly in the vertical direction, and can be used to provide support for the vehicle's engine and other structures. The middle frame assembly 2 is also constructed as a "U"-shaped structure open to the rear, and the rear part of the middle frame assembly 2 is connected to the front wall structure 4, so that the middle frame assembly 2 and the front wall structure 4 can jointly form a middle frame ring structure. When the middle front or side of the front cabin assembly is subjected to collision force, the collision force can be transmitted backward along the middle frame assembly 2 to the front wall structure 4, and the middle frame assembly 2 is constructed as a middle frame ring structure, so that the collision force can be dispersed and transmitted to weaken the effect of the collision force.

[0045] In addition, the bottom sub-frame assembly 3 is arranged at the bottom of the front cabin assembly. The bottom sub-frame assembly 3 is also constructed as a "U"-shaped structure open to the rear, and the rear part of the bottom sub-frame assembly 3 is connected to the front wall structure 4, so that the bottom sub-frame assembly 3 and the front wall structure 4 can jointly form a bottom sub-frame ring structure. When the front or side of the bottom of the front cabin assembly is subjected to a collision force, the collision force can be transmitted rearward along the bottom sub-frame assembly 3 to the front wall structure 4. The bottom sub-frame assembly 3 is constructed as a bottom sub-frame ring structure, so that the collision force can be dispersed and transmitted to weaken the effect of the collision force.

[0046] Furthermore, the cabin top assembly 1 is arranged at the top of the front cabin assembly, the middle frame assembly 2 is arranged in the middle of the front cabin assembly, and the middle frame assembly 2 is located below the cabin top assembly 1, and the bottom sub-frame assembly 3 is arranged at the bottom of the front cabin assembly, and the bottom sub-frame assembly 3 is located below the middle frame assembly 2. The cabin top assembly 1 and the bottom sub-frame assembly 3 are respectively connected to the middle frame assembly 2, so that the collision force exerted on any structure of the cabin top assembly 1, the middle frame assembly 2 and the bottom sub-frame assembly 3 can be transmitted to the other two, so as to be transmitted backward through the front structure 4, thereby increasing the transmission path of the collision force.

[0047] In this way, the front engine room assembly is formed into an engine room top ring structure, a middle frame ring structure and a bottom subframe ring structure, which can form a diffuse force transmission, thereby improving the structural stability of the front engine room assembly while ensuring the lightweight of the front engine room assembly, and increasing the force conduction path, weakening the effect of the force, and improving driving safety. At the same time, it can improve the NTF transmission function, evenly transmit and distribute the road excitation, reduce road noise and front-end yaw, and thus improve the user's riding experience.

[0048] According to the front cabin assembly of an embodiment of the present invention, by arranging a cabin top ring structure, a middle frame ring structure and a bottom subframe ring structure in the front cabin assembly, the conduction path of the vibration force can be increased, thereby weakening the effect of the vibration force, so as to improve the NVH performance of the entire vehicle, and reduce the NTF transmission function and road noise, thereby improving user comfort, and improving the structural stability of the front cabin assembly, increasing the collision force conduction path to improve the transmission efficiency of the collision force, ensuring the driving safety of the vehicle, and improving the user experience. In addition, it can ensure the lightweight of the vehicle, improve the vehicle's endurance performance, and have better use effects and a wider range of applications.

[0049] In some embodiments, the cabin top assembly 1 includes a headlight support beam 11 and two wheel arch rear reinforcement structures 13. The headlight support beam 11 is arranged to extend along the lateral direction of the vehicle. The two wheel arch rear reinforcement structures 13 are spaced apart and distributed along the left and right directions and extend along the front and rear directions. The front ends of the two wheel arch rear reinforcement structures 13 are respectively connected to the left and right ends of the headlight support beam 11 through the first connecting plate 12, and the rear ends of the two wheel arch rear reinforcement structures 13 are connected to the front surround structure 4.

[0050] Specifically, the cabin top assembly 1 is arranged on the upper part of the front cabin assembly, and as shown in FIG. Figure 2 As shown, the cabin top component 1 is provided with a headlight bracket beam 11 and a wheel house rear reinforcement structure 13. The headlight bracket beam 11 is located at the front end of the cabin top component 1 and extends laterally. There are two wheel house rear reinforcement structures 13. Both wheel house rear reinforcement structures 13 extend in the front-to-back direction, and the two wheel house rear reinforcement structures 13 are spaced apart and distributed laterally along the vehicle.

[0051] The cabin top assembly 1 is also provided with a first connecting plate 12, and there are two first connecting plates 12. The two first connecting plates 12 are also distributed at intervals along the lateral direction of the vehicle. The front ends of the two first connecting plates 12 are respectively connected to the left and right ends of the headlight bracket beam 11, and the rear ends of the two first connecting plates 12 are respectively connected to the front ends of the two wheel house rear reinforcement structures 13 in a one-to-one correspondence, so that the left and right ends of the headlight bracket beam 11 can be respectively connected to the two wheel house rear reinforcement structures 13 through the two first connecting plates 12.

[0052] And the rear ends of the two wheel house rear reinforcement structures 13 are connected to the front wall structure 4. In this way, the headlight bracket beam 11, the two first connecting plates 12, the two wheel house rear reinforcement structures 13 and the front wall structure 4 can together constitute the cabin top ring structure, so that when the front cabin assembly is subjected to a collision force, the collision force can be transmitted from the headlight bracket beam 11 to both sides respectively to weaken the effect of the force, and the cabin top ring structure can improve the lightweight and structural stability of the front cabin assembly, so as to improve the NTF transmission function, reduce road noise and front end lateral swing, and thus ensure the user's riding experience.

[0053] When actually setting, Figure 2 As shown, the first connecting plate 12 can be set to be inclined outward from front to back along the front-to-back direction, so that the front width of the annular structure on the top of the cabin is smaller, and the rear width of the annular structure on the top of the cabin is larger, so that the front cabin assembly as a whole can be streamlined, reducing the wind resistance when the vehicle is running, thereby reducing the vehicle's energy consumption and improving the vehicle's endurance performance.

[0054] In some embodiments, the headlight bracket beam 11 includes a first sub-section 111 and two second sub-sections 112. The first sub-section 111 extends horizontally, and the two second sub-sections 112 are respectively connected to the two ends of the first sub-section 111 and extend downward in the vertical direction. The front ends of the two first connecting plates 12 are respectively connected to the left and right ends of the first sub-section 111, and the lower ends of the second sub-sections 112 are connected to the middle frame assembly 2.

[0055] Specifically, the headlight support beam 11 is arranged to extend in the transverse direction of the vehicle, and as shown in FIG. Figure 2 As shown, the headlight bracket beam 11 is provided with a first sub-section 111 and a second sub-section 112. The first sub-section 111 is extended along the transverse direction of the vehicle. The front ends of the two first connecting plates 12 can be respectively connected to the upper parts of the left and right ends of the first sub-section 111, and the two second sub-sections 112 are extended vertically. The upper ends of the two second sub-sections 112 are respectively connected to the lower parts of the left and right ends of the first sub-section 111, and the lower ends of the two second sub-sections 112 are respectively connected to the middle frame assembly 2, so that the first sub-section 111 can be connected to the middle frame assembly 2 in the vertical direction through the two second sub-sections 112.

[0056] In this way, when the first sub-section 111 is subjected to a collision force, part of the collision force can be transmitted rearward along the two first connecting plates 12 to the two wheel house rear reinforcement structures 13, and then transmitted to the front wall structure 4; the other part of the collision force can be transmitted downward along the two second sub-sections 112 to the middle frame assembly 2, and then transmitted rearward to the front wall structure 4 through the middle frame assembly 2, so as to increase the transmission path of the force, and then disperse the force and weaken the effect of the force. The first sub-section 111 is connected to the middle frame assembly 2 through the two second sub-sections 112, which can improve the structural stability of the front cabin assembly in the vertical direction, improve the NTF transmission function, reduce road noise, and improve the user's riding experience.

[0057] In some embodiments, the cabin top assembly 1 also includes a front panel transverse tie rod 14 and a front panel support 15. The front panel transverse tie rod 14 extends in the left-right direction and is arranged between the headlight bracket beam 11 and the front panel structure 4. The two ends of the front panel transverse tie rod 14 are respectively connected to the two wheel house rear reinforcement structures 13 through two shock absorber towers 5 in a one-to-one correspondence. The front panel support 15 is connected between the front panel transverse tie rod 14 and the front panel structure 4.

[0058] Specifically, the cabin top assembly 1 is also provided with a front panel transverse rod 14 and a front panel support 15, which are both arranged between the headlight bracket beam 11 and the front panel structure 4. The front panel transverse rod 14 extends along the left and right directions of the vehicle, and shock absorber towers 5 are respectively provided at both ends of the front panel transverse rod 14. The shock absorber towers 5 are used to install shock absorbers. The two shock absorber towers 5 are also respectively connected to the two wheel house rear reinforcement structures 13 one by one, so that the two ends of the front panel transverse rod 14 can be respectively connected to the two wheel house rear reinforcement structures 13 one by one through the two shock absorber towers 5.

[0059] The front panel transverse tie rod 14 and the front panel structure 4 are spaced apart and distributed along the front and rear directions of the vehicle, and the front panel support member 15 is connected between the front panel transverse tie rod 14 and the front panel structure 4, that is, the front end of the front panel support member 15 is connected to the front panel transverse tie rod 14, and the rear end of the front panel transverse tie rod 14 is connected to the front panel structure 4.

[0060] In this way, when the headlight bracket beam 11 is collided, the collision force can be transmitted backward to the two wheel arch rear reinforcement structures 13, and a part of the collision force acting on the wheel arch rear reinforcement structure 13 can be transmitted backward to the front panel structure 4, and the other part can be transmitted to the front panel transverse tie rod 14, and then transmitted to the front panel support 15 through the front panel support 15, so as to be transmitted to the front panel structure 4 through the front panel support 15, which can increase the conduction path of the force, and in the process of conducting the force, the conduction direction of the force changes multiple times, thereby weakening the effect of the force, thereby ensuring the reliability of the cabin top assembly 1.

[0061] In addition, the front panel cross rod 14 can provide support for the lateral direction of the cabin top assembly 1, and the front panel support member 15 can provide support for the cabin top assembly 1 in the front and rear directions, thereby improving the structural stability of the cabin top assembly 1, reducing noise transmission, and improving the user's riding experience.

[0062] In some embodiments, the front panel support member 15 includes two support tube sections 151, the front end of each support tube section 151 is connected to the front panel cross rod 14 and the rear end is connected to the front panel structure 4, and the two support tube sections 151 are constructed to extend obliquely forward relative to the front panel structure 4 and in a direction away from each other.

[0063] Specifically, the front wall support member 15 is connected between the front wall cross rod 14 and the front wall structure 4. Figure 2As shown, the front panel support 15 is provided with a support pipe section 151, and there are two support pipe sections 151. The two support pipe sections 151 are spaced apart along the left and right directions of the vehicle. The front ends of the two support pipe sections 151 are connected to the front panel transverse tie rod 14, and the rear ends of the two support pipe sections 151 are connected to the front panel structure 4, so that the force at the front panel transverse tie rod 14 can be transmitted to the front panel structure 4 through the two support pipe sections 151 respectively, thereby improving the force transmission efficiency and ensuring the force transmission stability.

[0064] Furthermore, the two support pipe sections 151 construct a straight tubular structure and extend obliquely forward and away from each other relative to the front panel structure 4, that is, the distance between the front ends of the two support pipe sections 151 is greater than the distance between the rear ends of the two support pipe sections 151, so that the two support pipe sections 151 and the front panel transverse tie rod 14 can be jointly constructed into a triangle. The triangle has stability, which can improve the reliability of the front panel support member 15 in supporting the front panel transverse tie rod 14 and the front panel structure 4, improve the overall structural strength of the front cabin assembly, so as to improve the structural stability of the front cabin assembly, and the front panel support member 15 has a simple structure and low setting cost. The overall setting is a tubular structure, which can improve the lightweight, thereby improving the vehicle endurance performance and improving the user experience.

[0065] In addition, if Figure 3 As shown, the front panel support 15 is also provided with a reinforcing pipe section 152, which is extended along the transverse direction of the vehicle and is spaced apart and distributed between the front panel cross rod 14 and the front panel structure 4 along the front and rear directions of the vehicle. The left and right ends of the reinforcing pipe section 152 are respectively connected to the two supporting pipe sections 151, thereby improving the structural stability of the front panel support 15 and ensuring the reliability of the front panel support 15.

[0066] In some embodiments, the front cabin assembly also includes: a trunk beam 6, the front end of the trunk beam 6 is connected to the front of the middle frame assembly 2 through a transition structure 7, the rear end of the trunk beam 6 is connected to the front end of the wheel arch rear reinforcement structure 13, and the trunk beam 6 is located below the first connecting plate 12 and is at least partially constructed to be upward and inclined outward from front to back.

[0067] Specifically, if Figure 1 and Figure 5-Figure 6As shown, the front cabin assembly is also provided with a trunk bridge 6, which extends along the front and rear directions of the vehicle, and the front end of the trunk bridge 6 can be connected to the front of the middle frame assembly 2 through the adapter structure 7, and the rear end of the trunk bridge 6 can be connected to the front end of the wheel arch rear reinforcement structure 13, so that after the front end of the vehicle is hit, the collision force can be transmitted to the adapter structure 7 through the middle frame assembly 2, and then transmitted to the trunk bridge 6. The force transmitted to the trunk bridge 6 can be transmitted backward to the wheel arch rear reinforcement structure 13, and then transmitted to the front enclosure structure 4 through the wheel arch rear reinforcement structure 13, so as to increase the conduction path of the force.

[0068] Furthermore, the trunk bridge 6 is located below the first connecting plate 12 and is at least partially configured to tilt upward and outward from front to back. This allows a triangular ring structure to be defined between the trunk bridge 6, the second sub-portion 112, and the first connecting plate 12, thereby improving the structural stability of the front nacelle assembly. Furthermore, at least a portion of the trunk bridge 6 is configured to tilt upward and outward from front to back. When the trunk bridge 6 is deformed by force, it deforms outward to the left and right sides of the vehicle, preventing it from intruding into the passenger compartment and improving safety. Furthermore, in the event of a side collision, the collision force can first act on the trunk bridge 6 and then be transmitted through the trunk bridge 6, improving safety. Furthermore, the trunk bridge 6 can be configured as a hollow tubular beam to improve lightweighting and increase vehicle range.

[0069] In some embodiments, the middle frame assembly 2 includes a first anti-collision beam 21 and two front longitudinal beams 23. The first anti-collision beam 21 is extended in the transverse direction. The two front longitudinal beams 23 are spaced apart in the transverse direction and extend in the front-to-back direction. The front ends of the two front longitudinal beams 23 are provided with a transfer structure 7. The two transfer structures 7 are respectively connected to the rear side of the first anti-collision beam 21 through two first energy absorption boxes 22. The rear ends of the two front longitudinal beams 23 are respectively connected to the front structure 4.

[0070] Specifically, the middle frame assembly 2 is arranged in the middle of the front cabin assembly in the vertical direction, and Figure 1 As shown, the middle frame assembly 2 is provided with a first anti-collision beam 21 and a front longitudinal beam 23. The first anti-collision beam 21 is located at the front end of the middle frame assembly 2 and extends in the transverse direction. There are two front longitudinal beams 23. Both of the two front longitudinal beams 23 extend in the front-to-back direction, and the two front longitudinal beams 23 are spaced apart along the transverse direction of the vehicle. The front ends of the two front longitudinal beams 23 are respectively provided with a transfer structure 7, and the two transfer structures 7 can be connected to the rear side of the first anti-collision beam 21 through two first energy absorption boxes 22, and the rear ends of the two front longitudinal beams 23 are both connected to the front structure 4.

[0071] In this way, when a collision occurs at the front of the vehicle, the force can be transmitted to the two first energy absorption boxes 22 respectively through the first anti-collision beam 21, so as to weaken the force through the two first energy absorption boxes 22, and then transmitted rearward to the front panel longitudinal beam 23 through the transition structures 7 corresponding to the two first energy absorption boxes 22, so as to be transmitted rearward to the front panel structure 4 through the front panel longitudinal beam 23, and the first anti-collision beam 21, the two first energy absorption boxes 22, the two transition structures 7, the two front panel longitudinal beams 23 and the front panel structure 4 can together constitute a middle frame ring structure, so that after the front cabin assembly is subjected to the collision force, the collision force can be transmitted from the first anti-collision beam 21 to both sides respectively to weaken the effect of the force, and the middle frame ring structure can improve the lightweight and structural stability of the front cabin assembly, so as to improve the NTF transmission function, reduce road noise and front end sway, and thus ensure the user's riding experience.

[0072] Among them, Figure 3 As shown, a second connecting plate 16 can also be provided between the first anti-collision beam 21 and the headlight bracket beam 11. The second connecting plate 16 extends in the vertical direction. The upper end of the second connecting plate 16 is connected to the headlight bracket beam 11, and the lower end of the second connecting plate 16 is connected to the first anti-collision beam 21. This can increase the supporting force of the front cabin assembly in the vertical direction, thereby improving the structural stability of the front cabin assembly and increasing the conduction path of the force.

[0073] In some embodiments, the left and right sides of the front panel structure 4 are connected to the A-pillar structure 8, and the A-pillar structure 8 is extended in the vertical direction. The outer side of the rear end of the front panel longitudinal beam 23 is connected to the A-pillar structure 8, and the inner side of the rear end of the front panel longitudinal beam 23 is connected to the front panel structure 4.

Figure 3 and Figure 6 As shown, A-pillar structures 8 are respectively provided on the left and right sides of the front structure 4. The A-pillar structure 8 is extended in the vertical direction so that the force transmitted to the front structure 4 can be transmitted to the A-pillar structure 8, and then transmitted through the A-pillar structure 8, so that the transmission direction of the force can be changed to weaken the effect.

[0075] Furthermore, the outer side of the rear end of the front panel longitudinal beam 23 is connected to the A-pillar structure 8, and the inner side of the rear end of the front panel longitudinal beam 23 is connected to the front panel structure 4, so that when the force is transmitted rearward through the front panel longitudinal beam 23, part of the force can be transmitted to the A-pillar structure 8 through the outer side of the rear end of the front panel longitudinal beam 23, and the other part of the force can be transmitted to the front panel structure 4 through the inner side of the rear end of the front panel longitudinal beam 23, so as to increase the force transmission path and thereby weaken the effect of the force.

[0076] The width of the rear part of the front longitudinal beam 23 in the vertical direction is constructed to gradually increase from front to rear, so that the rear part of the front longitudinal beam 23 is trumpet-shaped. When the vehicle is subjected to a front collision, the collision force can be dispersed and transmitted through the front longitudinal beam 23, that is, the locally concentrated high-intensity collision force can be dispersed to a larger area, thereby improving the overall impact resistance and ensuring safety and stability.

[0077] In some embodiments, the bottom subframe assembly 3 includes a second anti-collision beam 31 and two subframe longitudinal beams 33.

[0082] In this way, when a collision occurs at the front of the vehicle, the collision force can act on the second anti-collision beam 31, so as to be transmitted to the two second energy absorption boxes 32 respectively through the second anti-collision beam 31, and the force after energy absorption by the second energy absorption box 32 can continue to be transmitted rearward to the corresponding subframe longitudinal beam 33. Part of the force can be transmitted to the front cross beam 34 and the middle cross beam 35 respectively when being transmitted by the subframe longitudinal beam 33, and the other part of the force can still be transmitted along the subframe longitudinal beam 33 to the front structure 4, thereby dispersing the force and changing the transmission direction of the force to weaken the effect of the force.

[0083] In addition, a front cross member 34 and a middle cross member 35 extending in the transverse direction of the vehicle are provided between the two sub-frame longitudinal beams 33 to provide support between the two sub-frame longitudinal beams 33 , thereby improving the structural stability between the two sub-frame longitudinal beams 33 , reducing road noise, and improving NTF transmission function.

The suspension structures 331 can prevent vibration force from being transmitted from the bottom sub-frame assembly 3 to the middle frame assembly 2, and then transmitted to the passenger compartment. In this way, the NVH performance of the vehicle can be improved and the riding comfort of the passengers can be ensured.
