Description

Technical Field

[0002] As people's living standards improve, automobiles have become an indispensable means of transportation. Vehicle safety has become a crucial factor in car selection. When a vehicle is impacted, the impact force is transmitted and dispersed through the internal longitudinal beam structure of the engine compartment to prevent severe damage and injury to passengers. Existing longitudinal beam force transmission structures often transfer the impact force to the sill beam via a torsion box. This torsion box is formed by welding together various sheet metal parts, resulting in complex overlapping layers. The sheet metal is mostly thin, with weak rigidity and poor force transmission. Furthermore, the linear force transmission design leads to high stress and severe damage after a collision, resulting in poor safety performance and room for improvement. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] The following is for reference. Figures 1-3 The engine compartment longitudinal beam force transmission assembly 100 according to an embodiment of the present invention has a simple structure and can effectively transmit collision force, thereby improving driving safety.

[0029] like Figures 1-3 As shown, the nacelle longitudinal beam force transmission assembly 100 according to an embodiment of the present invention includes: a front bulkhead reinforcing plate 1 and a front longitudinal beam 4.

[0030] The end of the front bulkhead reinforcing plate 1 is connected to the sill beam 2, and the rear side of the front bulkhead reinforcing plate 1 is connected to the front floor front crossbeam 3. The rear end of the front longitudinal beam 4 is connected to the front bulkhead reinforcing plate 1. The two sides of the rear end of the front longitudinal beam 4 are connected to the front bulkhead reinforcing plate 1 through the longitudinal beam reinforcing plate 5 and the longitudinal beam support plate 6, respectively. Both the longitudinal beam reinforcing plate 5 and the longitudinal beam support plate 6 are set to be inclined relative to the front longitudinal beam 4.

[0031] Among them, the engine compartment longitudinal beam force transmission assembly is located under the vehicle body. It can prevent the bumper from breaking or permanently deforming during low-speed collisions, protect the front and rear longitudinal beams of the vehicle body frame from permanent deformation or breakage during repairable collisions, and play an initial energy absorption role in high-speed collisions, play an initial energy absorption role in offset collisions, and play a role in evenly transmitting force during the collision process, avoiding uneven force on the left and right sides of the vehicle body and improving driving safety.

[0032] Specifically, the front bulkhead reinforcing plate 1 is configured as a plate-like structure, which is arranged laterally along the vehicle body. Two door sill beams 2 are connected to both ends of the front bulkhead reinforcing plate 1. The two door sill beams 2 are arranged symmetrically along the longitudinal direction of the vehicle and are parallel to each other, so that the front bulkhead reinforcing plate 1 and the two door sill beams 2 are both perpendicular to each other. The rear side of the front bulkhead reinforcing plate 1 is connected to the front floor front crossbeam 3. The front floor front crossbeam 3 is also arranged laterally along the vehicle body and is parallel to the front bulkhead reinforcing plate 1. There are two front longitudinal beams 4. One end of the two front longitudinal beams 4 is connected to the front bulkhead reinforcing plate 1, and the two front longitudinal beams 4 are perpendicular to the front bulkhead reinforcing plate 1. The two sides of the rear end of the front longitudinal beams 4 are respectively provided with longitudinal beam reinforcing plates 5 and longitudinal beam support plates 6. The longitudinal beam reinforcing plates 5 and longitudinal beam support plates 6 are both set to be inclined relative to the front longitudinal beams 4. One end of the longitudinal beam reinforcing plates 5 and longitudinal beam support plates 6 is connected to the front longitudinal beams 4, and the other end is connected to the front bulkhead reinforcing plate 1 to form a herringbone force transmission path.

[0033] Furthermore, when a frontal collision occurs, the front longitudinal beam 4 is the first to be subjected to the impact force. The two front longitudinal beams 4 are symmetrically arranged, which can evenly distribute the impact force. When the impact force is transmitted to the rear end of the front longitudinal beam 4, part of the force can be transmitted to the front bulkhead reinforcement plate 1 through the front longitudinal beam 4, and another part of the force can be transmitted to the front bulkhead reinforcement plate 1 through the longitudinal beam reinforcement plate 5 and the longitudinal beam support plate 6. The longitudinal beam reinforcement plate 5 and the longitudinal beam support plate 6 are inclined, so that the longitudinal beam reinforcement plate 5 and the longitudinal beam support plate 6 form a triangular structure with the front longitudinal beam 4 and the front bulkhead reinforcement plate 1 respectively. The stability of the triangle can improve the structural strength of the front longitudinal beam 4, and the impact force is dispersed and transmitted to the front bulkhead reinforcement plate 1 through the front longitudinal beam 4, the longitudinal beam reinforcement plate 5 and the longitudinal beam support plate 6, avoiding the front bulkhead reinforcement plate 1 from being subjected to excessive local stress and deformation. The front floor front crossbeam 3 is set on the rear side of the front bulkhead reinforcement plate 1. The impact force transmitted to the front bulkhead reinforcement plate 1 can be transmitted to the front floor front crossbeam 3, further dispersing the impact force, improving the structural strength of the vehicle body and increasing driving safety.

[0034] According to an embodiment of the present invention, the cabin longitudinal beam force transmission assembly 100, by setting longitudinal beam reinforcing plate 5 and longitudinal beam support plate 6, transmits the collision force on the front longitudinal beam 4 obliquely to both sides, thereby forming a herringbone force transmission structure. This reduces the concentrated force on the front bulkhead reinforcing plate 1 and sill beam 2, avoids deformation and breakage of the front bulkhead reinforcing plate 1 and sill beam 2 due to excessive force, improves driving safety, and has a simple structure, better performance, and wider applicability.

[0035] In some embodiments, such as Figures 1-3 As shown, the longitudinal beam reinforcing plate 5 is located outside the front longitudinal beam 4, and the front end of the longitudinal beam reinforcing plate 5 is attached to the outer side of the front longitudinal beam 4, while the rear end of the longitudinal beam reinforcing plate 5 is connected to the end of the front bulkhead reinforcing plate 1.

[0036] Specifically, the longitudinal beam reinforcement plate 5 is located on the outer side of the rear end of the front longitudinal beam 4, that is, the longitudinal beam reinforcement plate 5 is located on the rear end of the front longitudinal beam 4 near the sill beam 2. The front end of the longitudinal beam reinforcement plate 5 is attached to the outer side of the front longitudinal beam 4, and the rear end of the longitudinal beam reinforcement plate 5 is connected to the end of the front bulkhead reinforcement plate 1. The longitudinal beam reinforcement plate 5 is inclined relative to the front longitudinal beam 4, thereby forming a right-angled triangular structure with the longitudinal beam reinforcement plate 5, the front longitudinal beam 4, and the front bulkhead reinforcement plate 1. Triangles have stability, which can improve the structural stability of the front longitudinal beam 4, prevent the front longitudinal beam 4 from tilting and deforming towards the sill beam 2, and increase driving safety. At the same time, the collision force is transmitted through the front longitudinal beam 4 and then dispersed through the longitudinal beam reinforcement plate 5 to the front bulkhead reinforcement plate 1, avoiding the collision force from being too concentrated when transmitted to the front bulkhead reinforcement plate 1, which could lead to deformation or breakage of the front bulkhead reinforcement plate 1. This increases the structural strength of the front bulkhead reinforcement plate 1 and further improves driving safety.

[0037] In some embodiments, such as Figures 2-3 As shown, the engine compartment longitudinal beam force transmission assembly 100 also includes an A-pillar 7. The end of the front bulkhead reinforcement plate 1 is connected to the sill beam 2 through the A-pillar 7. At least part of the rear end of the longitudinal beam reinforcement plate 5 is connected to the A-pillar 7. That is, the rear end of the longitudinal beam reinforcement plate 5 can be partially connected to the A-pillar 7 and partially connected to the front bulkhead reinforcement plate 1. The A-pillar 7 is set perpendicular to the sill beam 2 in the longitudinal direction of the vehicle. The collision force is transmitted through the front longitudinal beam 4. When the force is transmitted to the rear end of the front longitudinal beam 4, it is dispersed and transmitted to the front bulkhead reinforcement plate 1 through the front longitudinal beam 4, the longitudinal beam reinforcement plate 5 and the longitudinal beam support plate 6 respectively. The longitudinal beam reinforcement plate 5 is partially connected to the A-pillar 7. The collision force can also be directly transmitted to the A-pillar 7 through the longitudinal beam reinforcement plate 5 and then to the sill beam 2. The collision force on the front bulkhead reinforcement plate 1 can also be transmitted to the sill beam 2 through the A-pillar 7. The A-pillar 7 converts the force in the horizontal direction to the vertical direction and then back to the horizontal direction. By changing the direction of force transmission, the impact of the collision force on the vehicle body is further weakened, and the structural strength of the vehicle body is improved.

[0038] In some embodiments, such as Figures 1-3 As shown, the longitudinal beam support plate 6 is located inside the front longitudinal beam 4, and the front end of the longitudinal beam support plate 6 is attached to the inner side of the front longitudinal beam 4, while the rear end of the longitudinal beam support plate 6 is attached to the front side of the front bulkhead reinforcing plate 1.

[0039] Specifically, the longitudinal beam support plate 6 is located on the outer side of the rear end of the front longitudinal beam 4, that is, the longitudinal beam support plate 6 is located on the rear end of the front longitudinal beam 4 away from the sill beam 2. The front end of the longitudinal beam support plate 6 is attached to the inner side of the front longitudinal beam 4, and the rear end of the longitudinal beam support plate 6 is attached to the front side of the front bulkhead reinforcement plate 1. The longitudinal beam support plate 6 is inclined relative to the front longitudinal beam 4, thereby forming a right-angled triangle structure with the longitudinal beam support plate 6, the front longitudinal beam 4, and the front bulkhead reinforcement plate 1. The triangle has stability, which can improve the structural stability of the front longitudinal beam 4, prevent the front longitudinal beam 4 from tilting and deforming away from the sill beam 2, and increase driving safety. At the same time, the collision force is transmitted through the front longitudinal beam 4 and then dispersed to the front bulkhead reinforcement plate 1 through the longitudinal beam support plate 6, avoiding the collision force from being too concentrated when transmitted to the front bulkhead reinforcement plate 1, which could lead to deformation or breakage of the front bulkhead reinforcement plate 1, thus increasing the structural strength of the front bulkhead reinforcement plate 1 and further improving driving safety.

[0040] In some embodiments, such as Figures 1-3 As shown, the engine compartment longitudinal beam force transmission assembly 100 also includes: a front subframe rear mounting bracket 8, which is connected to the lower surface of the front longitudinal beam 4 and connected to the front floor front crossbeam 3. The front subframe rear mounting bracket 8 and the sill beam 2 are spaced apart, and a bracket reinforcement plate 9 is provided between the front subframe rear mounting bracket 8 and the sill beam 2.

[0041] Specifically, the front subframe rear mounting bracket 8 is located below the front longitudinal beam 4, parallel to the front longitudinal beam 4, and connected to the lower surface of the front longitudinal beam 4. One end of the front subframe rear mounting bracket 8 is a free end, and the other end is connected to the front floor front crossbeam 3. The collision force is transmitted through the front longitudinal beam 4. When the force is transmitted to the rear end of the front longitudinal beam 4, it is dispersed through the front longitudinal beam 4, the longitudinal beam reinforcing plate 5, the longitudinal beam support plate 6, and the front subframe rear mounting bracket 8. The collision force dispersed to the front subframe rear mounting bracket 8 can be transmitted to the front floor front crossbeam 3. Both ends of the front floor front crossbeam 3 are connected to the sill beam 2, so the collision force can be transmitted to the sill beam 2 to reduce the damage to the vehicle body. The front subframe rear mounting bracket 8 and the sill beam 2 are spaced apart. A bracket reinforcing plate 9 is provided between the front subframe rear mounting bracket 8 and the sill beam 2 to improve the structural stability of the front subframe rear mounting bracket 8, prevent deformation of the front subframe rear mounting bracket 8, and increase driving safety.

[0042] Meanwhile, the front subframe rear mounting bracket 8 is perpendicular to the front floor front crossbeam 3, and the front floor front crossbeam 3 is perpendicular to the sill beam 2. The collision force changes direction four times during transmission, further weakening the impact of the collision force on the vehicle body and improving the structural strength of the vehicle body. In addition, multiple front floor longitudinal beams 11 are installed on the side of the front floor front crossbeam 3 away from the front subframe rear mounting bracket 8. In this embodiment, three beams are installed, which can further disperse the collision force transmitted to the front floor front crossbeam 3 and improve driving safety.

[0043] In some embodiments, such as Figures 1-3 As shown, one end of the bracket reinforcement plate 9 is connected to the rear mounting bracket 8 of the front subframe, and the other end of the bracket reinforcement plate 9 is connected to the sill beam 2; and along the front-rear direction of the vehicle, the end of the bracket reinforcement plate 9 connected to the rear mounting bracket 8 of the front subframe protrudes beyond the other end of the bracket reinforcement plate 9 connected to the sill beam 2.

[0044] Specifically, the front end of the bracket reinforcement plate 9 is fitted and connected to the inner side of the front subframe rear mounting bracket 8, and the rear end of the bracket reinforcement plate 9 is connected to the sill beam 2. Along the front-rear direction of the vehicle, the end of the bracket reinforcement plate 9 connected to the front subframe rear mounting bracket 8 protrudes beyond the other end connected to the sill beam 2. That is, the bracket reinforcement plate 9 is inclined relative to the front subframe rear mounting bracket 8, thereby forming a right-angled triangle structure between the bracket reinforcement plate 9, the front subframe rear mounting bracket 8, and the front floor front crossbeam 3. The triangle has stability, which can improve the structural stability of the front subframe rear mounting bracket 8, prevent the front subframe rear mounting bracket 8 from deforming, and increase driving safety. At the same time, the collision force is transmitted to the front subframe rear mounting bracket 8 through the front longitudinal beam 4, and then dispersed to the sill beam 2 through the bracket reinforcement plate 9, further dispersing the collision force, increasing the structural strength of the front subframe rear mounting bracket 8, and improving driving safety.

[0045] In some embodiments, such as Figures 1-3 As shown, the rear side of the front bulkhead reinforcement plate 1 is connected to the front floor front crossbeam 3 via the lower reinforcement beam 10. The lower reinforcement beam 10 is vertically positioned between the front bulkhead reinforcement plate 1 and the front floor front crossbeam 3. When the collision force is transmitted to the front bulkhead reinforcement plate 1 through the front longitudinal beam 4 and the longitudinal beam support plate 6, part of the collision force is transmitted to the A-pillar 7 along the front bulkhead reinforcement plate 1, and part of it is transmitted to the front floor front crossbeam 3 through the lower reinforcement beam 10 connected to the front bulkhead reinforcement plate 1. The collision force changes direction multiple times during the transmission process. By changing the direction of force transmission, the impact of the collision force on the vehicle body is further weakened, and the structural strength of the vehicle body is improved.

[0046] In some embodiments, such as Figures 1-3 As shown, there are multiple lower reinforcing beams 10, and these multiple lower reinforcing beams 10 are connected between the front bulkhead reinforcing plate 1 and the front floor front crossbeam 3, spaced apart laterally. In this embodiment, there are three lower reinforcing beams 10. Two lower reinforcing beams 10 are arranged corresponding to the two front longitudinal beams 4, which can support the front longitudinal beams 4. The other lower reinforcing beam 10 is located in the middle of the two lower reinforcing beams 10. The arrangement of multiple lower reinforcing beams 10 can disperse the impact force transmitted by the front bulkhead reinforcing plate 1, so that the impact force is evenly applied to the front floor front crossbeam 3, avoiding deformation of the front floor front crossbeam 3 due to excessive local stress, and improving the structural strength of the front floor front crossbeam 3.

[0047] In some embodiments, at least one of the front longitudinal beam 4, the front bulkhead reinforcing plate 1, the longitudinal beam reinforcing plate 5, the longitudinal beam support plate 6, the sill beam 2, and the front floor front crossbeam 3 is formed by profile extrusion molding. It is understood that the improved mechanical properties of profile extrusion molding and the full utilization of the material's plasticity are unmatched by other forging methods, thereby ensuring the quality after connection. Moreover, the time cost during processing is relatively small, the operation is simpler, the manufacturing process is optimized, and the force transmission effect is improved.

[0048] Specifically, in this embodiment, at least one of the front longitudinal beam 4, front bulkhead reinforcing plate 1, longitudinal beam reinforcing plate 5, longitudinal beam support plate 6, sill beam 2, and front floor crossbeam 3 can be extruded from profiles to form cavities in the engine compartment longitudinal beams. This ensures that the resulting engine compartment longitudinal beam force transmission assembly 100 can form multiple force transmission channels, providing a force transmission effect, thereby improving the overall body strength and rigidity. Furthermore, extrusion molding can reduce the number of parts, allowing at least one of the front longitudinal beam 4, front bulkhead reinforcing plate 1, longitudinal beam reinforcing plate 5, longitudinal beam support plate 6, sill beam 2, and front floor crossbeam 3 to be integrated into a single design, reducing the design and development of molds and fixtures, and thus lowering manufacturing costs.

[0049] The present invention also proposes a vehicle.

[0050] The vehicle according to an embodiment of the present invention is provided with the engine compartment longitudinal beam force transmission assembly 100 of any of the above-mentioned features.

[0051] According to an embodiment of the present invention, the vehicle is provided with a cabin longitudinal beam force transmission assembly 100. The cabin longitudinal beam force transmission assembly 100, through the provision of longitudinal beam reinforcing plates 5 and longitudinal beam support plates 6, transmits the collision force on the front longitudinal beam 4 obliquely to both sides, thereby forming a herringbone force transmission structure. This reduces the concentrated force on the front bulkhead reinforcing plate 1 and the sill beam 2, and avoids deformation and breakage of the front bulkhead reinforcing plate 1 and the sill beam 2 due to excessive force, thereby improving driving safety. Moreover, the structure is simple, the effect is better, and the application range is wider.
