[0075] Reference Figure 1-Figure 10 The present application provides a vehicle front cabin assembly. The vehicle front cabin assembly includes an A-pillar 20. The A-pillar 20 extends along the length direction of the vehicle. Two A-pillars 20 are arranged at intervals along the width direction of the vehicle. The front dash upper cross beam 10 extends along the width direction of the vehicle, the front dash upper cross beam 10 is connected to the dash panel 30, and both ends of the front dash upper cross beam 10 are connected to the A-pillar 20. The front dash upper cross beam 10 is tightly connected to the A-pillar 20 to form a complete Y-direction force transmission path, which can provide support and protection, and enhance the stability and safety of the dash panel 30 and the entire vehicle body structure. The front dash upper cross beam 10 is arranged above the dash panel 30 and overlapped with the dash panel 30. Thereby, the structure of the front dash upper cross beam 10 is stronger and more solid, the shear force it is subjected to is greatly improved, the force transmission path is more stable, and the aluminum alloy material used will not cause a significant impact on the weight.
[0076] In some embodiments of the present application, a front wheel housing 50 is further included. The two front wheel housings 50 are arranged at intervals along the width direction of the vehicle. Both ends of the front cowl upper cross member 10 are connected to the two front wheel housings 50 respectively.
[0077] like Figure 2 As shown, in some embodiments of the present application, the front upper cross beam 10 includes a main body portion 11 and connecting portions 12 connected to both ends of the main body portion 11. Optionally, the connecting portion 12 of the front upper cross beam 10 is overlapped to the A-pillar 20. The main body portion 11 of the front upper cross beam 10 is overlapped to the front wheel housing 50.
[0078] In some embodiments of the present application, a front wall upper cross beam lower connecting member 13 is also included. Figure 2 As shown, the lower connecting piece 13 of the front enclosure upper cross beam is arranged above the front wheel cover 50, and the main body of the front enclosure upper cross beam 10 is arranged above the lower connecting piece 13 of the front enclosure upper cross beam, so that the front enclosure upper cross beam 10 is overlapped and fixed with the front wheel cover 50.
[0079] In some embodiments of the present application, the front wheel cover 50 includes a shock absorber mounting portion 51. The shock absorber mounting portion 51 is used to mount a shock absorber.
[0080] like Figure 3-4 As shown, in some embodiments of the present application, a front cabin stabilizer bar 60 is further included, and both ends of the front cabin stabilizer bar 60 are respectively connected to the two front wheel covers 50. The front upper cross beam 10, the front cabin stabilizer bar 60, and the two front wheel covers 50 form a structure as shown in FIG. Figure 4 The annular structure shown. It can enhance the dynamic stiffness of the shock absorber seat tower in the Y direction. Preferably, the front cabin stabilizer bar 60 is made of aluminum profile. The cross section of the front cabin stabilizer bar 60 is a closed shape. The front cabin stabilizer bar 60 is screwed and connected to the front wheel cover 50 in the Z direction to form a stable force transmission structure in the Y direction. The front wheel cover 50 is connected to the upper cross beam 10 of the front enclosure by screwing, and the front cabin stabilizer bar 60 is screwed and connected to the front wheel cover 50 in the Z direction to form a closed-loop frame at the front cabin wheel cover again, which effectively transmits and disperses the force from the shock absorber tower in the X direction to the Y direction, which can greatly improve the dynamic stiffness of the front cabin wheel cover, especially in the Y direction, and has great benefits for the torsional stiffness of the whole vehicle, thereby improving the passengers' requirements for the comfort of the whole vehicle.
[0081] In some embodiments of the present application, in the projection on the vertical plane, at least part of the front cowl upper cross beam 10 is located above the front cabin stabilizer bar 60. That is, along the height direction of the vehicle, the front cowl upper cross beam 10 is higher than the front cabin stabilizer bar 60. And along the length direction of the vehicle, the front cabin stabilizer bar 60 and the front cowl upper cross beam 10 are arranged at intervals. In the projection on the horizontal plane, the front cowl upper cross beam 10 is located behind the front cabin stabilizer bar 60. That is, along the length direction of the vehicle, the front cowl upper cross beam 10 is further back than the front cabin stabilizer bar 60. After the above components are connected, a stable structural ring feature is formed, which effectively improves the dynamic stiffness of the front wheel cover 50 and the torsional stiffness of the whole vehicle. In this embodiment, along the length direction of the vehicle, the shock absorber mounting part 51 is located between the front cowl upper cross beam 10 and the front cabin stabilizer bar 60. By arranging the front cowl upper cross beam 10 and the front cabin stabilizer bar 60 on both sides of the shock absorber mounting part 51, the stabilizing effect on the shock absorber mounting part 51 is improved, the stiffness of the wheel cover is improved, and the shock absorption effect is improved.
[0082] In some embodiments of the present application, a front cross beam 31 of the front wall panel is also included. Figure 5-7 As shown, both ends of the dash panel front cross beam 31 are connected to the front wheel housing 50 respectively. The dash panel upper cross beam 10, the two front wheel housings 50, and the dash panel front cross beam 31 form a ring structure. After the above components are connected, a stable structural ring feature is formed, which effectively improves the stability of the entire dash panel frame of the front cabin, thereby improving the bending and torsion resistance of the cabin, and at the same time improves the X-direction resistance of the dash panel and reduces the collision intrusion amount.
[0083] Optionally, the front wheel housing 50 is a one-piece casting 32 .
[0084] like Figure 5 As shown, the dash panel 30 includes a dash panel front cross beam 31, and castings 32 arranged on both sides of the dash panel front cross beam 31 along the width direction of the vehicle body, and the castings 32 are connected to the front wheel cover 50. The dash panel front cross beam 31 is riveted to the casting 32. The casting 32 is connected to the front longitudinal beam 90 and the front wheel cover 50 by riveting to the outermost side, thereby forming a Y-direction C-shaped force transmission structure. The above-mentioned cast aluminum front wheel cover 50 is connected to the dash panel upper cross beam 10 to form a C-shaped structure, so that the dash panel upper cross beam 10, the dash panel front cross beam 31 and the front wheel cover 50 once again form a frame at the bottom of the passenger compartment. The entire frame of the vehicle, from left to right and from top to bottom, is composed of interconnected "mouth"-shaped frames, just like a horizontally and vertically staggered net to form a more complete and integrated resistance to external impact, which has a greater improvement effect on the collision stability and torsion of the vehicle body passenger compartment. The dash panel front cross beam 31 reinforces the dash panel 30 and improves the torsional rigidity of the front compartment of the vehicle body.
[0085] like Figure 7As shown in the figure, a second partition 311 is provided inside the front cross beam 31 of the front bulkhead. The extending direction of the second partition 311 is the same as that of the front cross beam 31 of the front bulkhead. That is, both the second partition 311 and the front cross beam 31 of the front bulkhead extend along the width direction of the vehicle. Preferably, there are two second partitions 311, so that the cross-section of the main body of the front cross beam 31 of the front bulkhead is in the shape of "mu". The two second partitions 311 are spaced along the height direction of the vehicle. It can improve the intrusion amount into the occupant compartment during a collision and the force transmission during a side collision.
[0086] In some embodiments of the present application, in the height direction of the vehicle, the front cross beam 31 of the front bulkhead is located below the upper cross beam 10 of the front bulkhead. In the projection on the vertical plane, the front cross beam 31 of the front bulkhead and the upper cross beam 10 of the front bulkhead at least partially overlap, which has a better strengthening effect on the front wheelhouse 50. It improves the strength of the annular structure formed by the upper cross beam 10 of the front bulkhead, the two front wheelhouses 50, and the front cross beam 31 of the front bulkhead. There is better force transmission in both the width direction and the height direction of the vehicle.
[0087] As Figure 7-9 shown in the figure, in some embodiments of the present application, it further includes a front roof cross beam 40. The two end portions of the front roof cross beam 40 are respectively connected to the two A-pillars 20. In this embodiment, the upper cross beam 10 of the front bulkhead, the front roof cross beam 40, and the two A-pillars 20 are connected to form an annular structure. Through the above structure, the structures at the windshield position are tightly connected together to form a strengthened frame structure, which can enhance the torsional stiffness of the whole vehicle.
[0088] As Figure 8 shown in the figure, in some embodiments of the present application, the front roof cross beam 40 includes a front roof cross beam upper plate 41 and a front roof cross beam lower plate 42. The front roof cross beam upper plate 41 and the front roof cross beam lower plate 42 surround to form a cavity with a closed cross-section. It improves the shear force of the front roof cross beam 40 assembly.
[0089] As Fig. 9 shown in the figure, in some embodiments of the present application, the A-pillar 20 includes an A-pillar inner panel 21 and an A-pillar outer panel 22. The A-pillar inner panel 21 and the A-pillar outer panel 22 surround to form a cavity with a closed cross-section. A reinforcing beam 23 is provided between the A-pillar inner panel 21 and the A-pillar outer panel 22. Optionally, the material of the A-pillar 20 is carbon steel, and the material of the reinforcing beam 23 is aluminum profile. Through the arrangement of the A-pillar inner panel 21, the A-pillar outer panel 22 and the reinforcing beam 23, the structural strength of the A-pillar 20 is greatly improved, and the smoothness of the X-direction force transmission is resisted.
[0090] As Fig.10As shown, in some embodiments of the present application, a shock tower front connecting rod 52 is also included, and the front end of the shock tower front connecting rod 52 is connected to the front energy absorption box column 70, and the rear end of the front connecting rod of the front wheel cover 50 is connected to the front wheel cover 50. The front energy absorption box column extends along the height direction of the vehicle. Preferably, the shock tower front connecting rod 52 is a closed aluminum extrusion with good force transmission and force bearing stability. The front end of the shock tower front connecting rod 52 is welded to the upper vertical surface of the front energy absorption box column 70, and the rear end is welded to the X-direction vertical surface of the front end of the front wheel cover 50 to form a stable X-direction force transmission path. Fig.10 As shown, based on the above embodiment, an X-direction force transmission path is formed on the inner side of the front cabin side beam, and the front end of the front cabin upper side beam 80 overlaps with the front longitudinal beam 90, and the rear end overlaps with the shock absorber and extends backward to connect with the A-pillar 20, forming a separate force transmission path. The two together constitute a double force transmission path structure on the upper part of the front longitudinal beam 90.
[0091] In some embodiments of the present application, the front energy absorption box pillar 70 extends in the vehicle height direction, and the front side of the front energy absorption box pillar 70 is connected to the anti-collision beam through the energy absorption box, and the rear side is connected to the front longitudinal beam 90 .
[0092] like Fig.10 As shown, in some embodiments of the present application, a front cabin upper side beam 80 is also included, the front portion of the front cabin upper side beam 80 is connected to the front energy absorption box column 70, the rear portion of the front cabin upper side beam 80 is connected to the A-pillar 20, and the middle portion of the front cabin upper side beam 80 is connected to the front wheel cover 50. In the vehicle, along the length direction of the vehicle, the front energy absorption box column 70 is located in front of the front wheel cover 50, and the A-pillar is located behind the front wheel cover 50. Along the width direction of the vehicle, the front cabin upper side beam 80 is connected to the outside of the front wheel cover 50 and the outside of the front energy absorption box column 70. The front end of the front cabin upper side beam 80 is connected to the front energy absorption box column 70 connecting plate by X-direction screw connection, and the rear end is screwed to the cast aluminum front wheel cover 50 until it extends to the A-pillar outer plate 22, forming another body X-direction force transmission path. The front cabin upper side beam 80 increases the force transmission path in the front and rear directions of the vehicle and strengthens the wheel cover.
[0093] In some embodiments of the present application, in the vehicle height direction, the shock tower front connecting rod 52 is arranged above the front longitudinal beam 90. In the projection on the vertical plane, the shock tower front connecting rod 52 overlaps with the front longitudinal beam 90 to better transmit force in the front and rear directions. The front upper cross beam 10 and the front cross beam 31 of the front wall reinforce the wheel housing, so that force can be better transmitted through the shock tower front connecting rod 52. In the vehicle height direction, the shock tower front connecting rod 52 is arranged in front of the front cabin stabilizer bar 60.
[0094] According to the above, through structural optimization, multiple force transmission paths are formed above the longitudinal beam to transmit the force to the A-pillar 20, the cross beam on the windshield, etc., which can effectively disperse and transmit the collision force and help resist the intrusion into the passenger compartment during a collision.
[0095] As Figure 11-Figure 12 shown, in some embodiments of the present application, the upper front crossmember 10 includes a body portion 11 and a connecting portion 12. The body portion 11 extends along the width direction of the vehicle. The body portion 11 is a hollow tube, and its cross-section is a closed shape. The connecting portion 12 is provided at both ends of the body portion 11, and the connecting portion 12 is connected to the A-pillar 20. The upper front crossmember 10 adopts a hollow tube structure with a cross-section of a closed shape.
[0096] As Figure 2 shown, in some embodiments of the present application, a first partition 111 is provided inside the body of the upper front crossmember 10, and the extending direction of the first partition 111 is the same as the extending direction of the upper crossmember body. That is, the first partition 111 extends along the width direction of the vehicle. In this embodiment, the body portion 11 is configured to have a "day" - shaped cross-section.
[0097] In some embodiments of the present application, the first partition 111 extends along the height direction of the vehicle. That is, both ends of the first partition 111 in the height direction are connected to the inner wall surface of the upper crossmember body.
[0098] In some embodiments of the present application, connecting portions 12 are provided at both ends of the body portion 11 along its length direction. The connecting portion 12 has two relatively arranged free ends to form an open structure. In this embodiment, the body portion 11 is configured to have a "ji" - shaped cross-section.
[0099] In some embodiments of the present application, the opening of the connecting portion 12 faces the rear of the vehicle.
[0100] The second aspect of the present application provides a vehicle, including the above-mentioned vehicle front cabin assembly.
[0101] For the vehicle according to the second aspect of the present application, by adding the improved upper front crossmember 10 and other connecting components in the vehicle front cabin assembly, multiple force transmission paths are formed, thereby enhancing the strength and stability of the entire vehicle body structure. This enables the vehicle to better absorb and disperse energy during a collision or other external impacts and protects the safety of the occupants in the occupant compartment. Through the arrangement of various connecting components, stable force transmission paths and frame structures are formed, improving the stability of the whole vehicle structure. This has a positive impact on maintaining the handling performance, driving comfort and driving stability of the vehicle.
[0102] According to this solution, the vehicle front compartment assembly is used for a new energy sports car. The front compartment is made of aluminum alloy, and the passenger compartment is made of carbon fiber. The whole body is 40%-50% lighter than a steel body, which can greatly improve the endurance of the vehicle. The front wheel cover 50 is changed from traditional sheet metal welding to a cast aluminum wheel cover, and its structural strength and dynamic stiffness are greatly improved. A closed aluminum extrusion front compartment stabilizer bar 60 is specially designed between the front wheel covers 50. The left and right ends are connected to the front wheel covers 50 through Z-direction screw connections to form a stable force transmission structure in the Y-direction to enhance the Y-direction dynamic stiffness of the shock absorber seat tower. The upper cross beam 10 of the front panel under the windshield cover is changed from the previous "ji" - shaped structure lapped with the front panel 30 to the current "ri" - shaped closed beam structure and then lapped with the front panel 30. In this way, the upper cross beam 10 of the front panel has a stronger and more solid structure, the shear force it receives is greatly increased, the force transmission path is more stable, and the aluminum alloy material used will not have a great impact on the weight.
