Description

Technical Field

[0001] The invention relates to an automobile frame structure, in particular to a front-end frame structure and an automobile. Background Art

[0002] Currently, automobile crash test regulations are becoming increasingly stringent, with increasing emphasis on passenger compartment safety. C-IASI (China Insurance Automobile Safety Index) has released testing and evaluation procedures for 25% offset frontal collisions, also known as small offset collisions. Most existing vehicle body structures are designed for frontal and 40% offset collisions. 25% offset frontal collisions impose greater local forces, and the front bumper beams, energy absorption boxes, and other structures of most models have low overlap with the barrier during small offset collisions. This results in a lack of effective structural integrity, an inability to effectively transmit collision forces, and inadequate dissipation of collision energy. This can even lead to severe deformation of the A-pillar area and the passenger compartment, causing significant deformation that can easily cause physical injury to occupants, and in severe cases, even endanger their lives.

[0003] The existing front body structure of a vehicle, used to improve the performance of frontal offset collisions, includes a front anti-collision beam, a cabin side beam assembly, and a cabin upper side beam assembly. The cabin side beam assembly is located at the rear of the front anti-collision beam, and the cabin upper side beam assembly is located on the vehicle's outer side of the cabin side beam assembly. A triangular connecting plate is connected between the cabin upper side beam assembly and the front end of the cabin side beam assembly. This design transfers limited collision energy to the cabin side beam assembly in the early stages of a collision. During a collision, especially after the barrier passes through the triangular connecting plate, the cabin upper side beam assembly can only absorb energy. The cabin side beam assembly basically does not participate in deformation and energy absorption. The rear end of the cabin upper side beam assembly is rigidly connected to the upper part of the cab, resulting in the collision energy being transferred from the cabin upper side beam assembly to the upper part of the cab. This makes it easy for the upper part of the cab to intrude more, threatening the safety of the occupants.

[0004] Therefore, how to reduce cab intrusion and improve frontal offset collision performance by 25% has become a technical problem that needs to be urgently solved in this field. Summary of the Invention

During a collision, the oblique rear collision force can be transmitted to the cabin side beam assembly 3, and the collision energy can be dispersed laterally to the cabin side beam assembly 3, making it easier to bend and absorb energy.

[0071] In some specific embodiments, Figure 10 As shown, the cabin side beam assembly 3 includes a cabin side beam inner plate 31 and a cabin side beam outer plate 32, and the cabin side beam inner plate 31 and the cabin side beam outer plate 32 are combined to form a box structure with a rectangular cross-section. In the front end area of ​​the cabin side beam inner plate 31 and the cabin side beam outer plate 32, a cabin side beam inner plate through hole 313 is provided on the side of the cabin side beam inner plate 31, and a cabin side beam outer plate through hole 322 is provided on the cabin side beam outer plate side 327 of the cabin side beam outer plate 32. The force transmission member 14 passes through the cabin side beam outer plate through hole 322 of the cabin side beam outer plate 32 and is connected to the cabin side beam inner plate through hole 313 of the cabin side beam inner plate 31. Generally, the end of the force transmission member 14 can be connected to the cabin side beam inner plate through hole 313 of the cabin side beam inner plate 31 by welding, such as by carbon dioxide shielded welding.

[0072] Among them, the cabin side beam inner plate 31 and the cabin side beam outer plate 32 are both U-shaped structures. The cabin side beam inner plate 31 extends outward to form the cabin side beam inner plate flange 328, and the cabin side beam outer plate 32 extends outward to form the cabin side beam outer plate flange 326. The cabin side beam outer plate flange 326 and the cabin side beam inner plate flange 328 sandwich the flange of the cabin side beam internal reinforcement plate 33 between the two, thereby forming a box-type structure with a rectangular cross-section.

[0073] Further, if Figure 11As shown, the cabin side beam internal reinforcement plate 33 is located inside the box structure and is installed on the cabin side beam inner plate 31. The cabin side beam internal reinforcement plate 33 is generally in the shape of a "bridge", that is, the shape of an arch bridge, with a curved shape convex outward and the top of the bridge facing outward from the vehicle. The two ends of the cabin side beam internal reinforcement plate 33 are connected to the cabin side beam inner plate 31 at the first cabin side beam internal reinforcement plate overlap surface 331 and the second cabin side beam internal reinforcement plate overlap surface 332. In addition, a number of cabin side beam collapse limit plates are also provided on the cabin side beam internal reinforcement plate 33. Figure 11 In the illustrated embodiment, there are two nacelle side beam collapse limit plates, namely a nacelle side beam front collapse limit plate 34 and a nacelle side beam rear collapse limit plate 35 .

[0074] In some embodiments, a first collapse guide rib 311 and a second collapse guide rib 312 are provided on the cabin side beam inner plate 31. The first collapse guide rib 311 and the second collapse guide rib 312 both extend in the up-down direction. In the front-back direction, the first collapse guide rib 311 is located between adjacent cabin side beam collapse limit plates, and the second collapse guide rib 312 is located in front of the first collapse guide rib 311. Specifically, Figure 11 In the illustrated embodiment, in the fore-aft direction, the first crush guide rib 311 is located between the nacelle side beam front crush limit plate 34 and the nacelle side beam rear crush limit plate 35, and the second crush guide rib 312 is located between the nacelle side beam front crush limit plate 34 and the first nacelle side beam inner reinforcement plate overlap surface 331. Furthermore, the first crush guide rib 311 is a concave crush guide rib, while the second crush guide rib 312 is a convex crush guide rib. During a vehicle collision, the first crush guide rib 311 and the second crush guide rib 312 bend in opposite directions, resulting in the nacelle side beam assembly 3 adopting a three-stage Z-shaped bending pattern. This is more stable than other conventional crush guide structures and also offers greater stability and strength compared to other bent configurations.

[0075] In addition, a third crush guide rib 321 is provided on the cabin side beam outer plate 32. The third crush guide rib 321 extends in the up-down direction. The third crush guide rib 321 is a crush guide concave rib. In the front-to-back direction, the third crush guide rib 321 is located at the upper bridge-shaped portion of the cabin side beam inner reinforcement plate 33 and is close to the first crush guide rib 311. When a vehicle collides, the third crush guide rib 321 and the first crush guide rib 311 have the same bending and deformation direction, which helps to promote the bending and deformation of the cabin side beam assembly 3.

[0078] In some embodiments, the cabin upper side beam assembly 2 includes a cabin upper side beam outer plate and a cabin upper side beam inner plate, and the cabin upper side beam outer plate and the cabin upper side beam inner plate are combined to form a box-type structure with a rectangular cross section. Specifically, Figure 7As shown, the cabin upper side beam outer plate includes a cabin upper side beam front section outer plate 21 and a cabin upper side beam rear section outer plate 22 which are connected in sequence from front to back, and the cabin upper side beam inner plate includes a cabin upper side beam front section inner plate 23, a cabin upper side beam middle section inner plate 24, and a cabin upper side beam rear section inner plate 25 which are connected in sequence from front to back, and a cabin upper side beam rear section lower plate 26 is installed at the lower part of the cabin upper side beam rear section inner plate 25, and a cabin upper side beam rear section lower plate 26 is provided with a collapse rib 261 which extends in the up and down direction, and the cabin upper side beam rear section lower plate 26 also has a cabin upper side beam rear section lower plate lap joint surface 262. Moreover, the front section outer plate 21 of the cabin upper side beam has a first front section outer plate lap surface 211 and a second front section outer plate lap surface 212 of the cabin upper side beam, and the first front section outer plate lap surface 211 and the second front section outer plate lap surface 212 of the cabin upper side beam are located at the front end of the front section outer plate 21 of the cabin upper side beam.

A weakening hole is provided on the cabin upper side beam assembly 2, specifically, as Figure 8 As shown, a first weakening hole 221 and a second weakening hole 222 are provided at the rear end of the cabin upper side beam rear section outer plate 22. The first weakening hole 221 and the second weakening hole 222 help the cabin upper side beam assembly 2 to achieve bending deformation when a collision occurs, and form a cabin upper side beam rear section outer plate overlap surface 223 at the rear end of the cabin upper side beam rear section outer plate 22. Figure 9 As shown, the cabin top side beam middle section inner plate 24 has a first cabin top side beam middle section inner plate lap surface 241 and a second cabin top side beam middle section inner plate lap surface 242. The first cabin top side beam middle section inner plate lap surface 241 is located at the side of the cabin top side beam middle section inner plate 24, and the second cabin top side beam middle section inner plate lap surface 242 is located at the bottom of the cabin top side beam middle section inner plate 24.

[0079] As a specific embodiment, the upper side beam assembly 2 of the engine compartment is generally arc-shaped, and the cross-sectional area of the upper side beam assembly 2 of the engine compartment gradually increases from front to back. On the one hand, the upper side beam assembly 2 of the engine compartment can have a large overlapping area with the barrier in the left-right direction, effectively transferring the collision energy to the side beam assembly 3 of the engine compartment and reducing the intrusion amount of the collision into the passenger compartment of the vehicle; on the other hand, the upper side beam assembly 2 of the engine compartment is an arc-shaped structure, having a certain reverse thrust, increasing the energy absorption effect, and the energy absorption is more gentle and sufficient.

[0080] As Figure 1 and Figure 14 shown, a second round bulge reinforcement assembly 7 can be provided between the side beam assembly 3 of the engine compartment and the upper side beam assembly 2 of the engine compartment, so that the side beam assembly 3 of the engine compartment, the upper side beam assembly 2 of the engine compartment, and the second round bulge reinforcement assembly 7 form a Chinese character "日" shaped frame. Through the second round bulge reinforcement assembly 7, the collision energy can be dispersed and transferred from the upper side beam assembly 2 of the engine compartment to the side beam assembly 3 of the engine compartment, reducing the transfer of collision energy into the cab.

Looking down from above, the side beam A-pillar connector 51, the outer lining plate 52 of the rear section of the side beam, the rear section 54 of the side beam, and the inner lining plate 53 of the rear section of the side beam of the rear section of the engine compartment side beam assembly 5 are in the structural shape of a Chinese character "ge", forming a distributed force transmission structure. Both ends of the reinforcing crossbeam assembly 4 are respectively connected to an engine compartment side beam rear section assembly 5, so that the collision crossbeam assembly 8, the engine compartment side beam assembly 3, the engine compartment side beam rear section assembly 5, and the reinforcing crossbeam assembly 4 are connected to form a closed frame structure.

[0092] When a 25% offset frontal collision occurs to the vehicle, such as Figure 1As shown in the figure, the end of the collision crossbeam assembly 8 collides with the barrier. Since the overall structure of the engine room side beam sealing plate assembly 1 is a wedge-shaped structure that slopes backward, and due to the provision of the force transmission member 14, part of the collision force borne by the upper engine room side beam assembly 2 can be dispersed and transmitted to the engine room side beam assembly 3. Moreover, since the first drum bulge reinforcement assembly 6 and the second drum bulge reinforcement assembly 7 are provided between the engine room side beam assembly 3 and the upper engine room side beam assembly 2, the engine room side beam assembly 3, the upper engine room side beam assembly 2, the first drum bulge reinforcement assembly 6, and the second drum bulge reinforcement assembly 7 form a Chinese character "mu" - shaped frame. During the 25% offset frontal collision, the "mu" - shaped frame mainly absorbs and transmits the collision energy. The first drum bulge reinforcement assembly 6 and the second drum bulge reinforcement assembly 7 can also disperse and transmit part of the collision force borne by the upper engine room side beam assembly 2 to the engine room side beam assembly 3, enabling the engine room side beam assembly to continuously disperse and absorb the collision energy and reduce the collision energy borne by the upper engine room side beam assembly. Moreover, a crush guiding rib is provided in the middle section of the engine room side beam assembly 3 to enable it to fully deform and absorb energy. The rear section assembly 5 of the engine room side beam is provided with a force - dispersing transmission structure, which can disperse and transmit the energy to the reinforcement crossbeam assembly 4, the floor of the lower part of the body - in - white, and the sill beam; a vertical weakening hole and a crush guiding rib are provided at the rear end of the upper engine room side beam assembly 2 to enable it to crush and absorb energy, reducing the transmission of collision energy to the upper part of the cab, thereby reducing the intrusion of the cab and achieving the purpose of improving the 25% offset frontal collision performance. Thus, through the structural improvement of the front - end frame structure, it can deform and absorb energy, effectively transmit the collision energy to the floor and sill of the lower part of the cab, reduce the intrusion amount into the upper part of the cab, protect the occupants, and thus improve the 25% offset frontal collision performance.
