Description

Technical Field

[0001] This invention relates to the field of vehicle technology, specifically to a reinforced structure for rear seat anchor points, a high-voltage electrical distribution box, and a vehicle. Background Technology

[0002] With the booming development of the automotive industry and the continuous improvement of people's living standards, automobiles have evolved from luxury goods to indispensable daily necessities in modern society. Against this backdrop, the importance of vehicle safety has become increasingly prominent, becoming a primary consideration in the design and manufacturing process.

[0003] As a fundamental component ensuring passenger safety, car seats are directly related to passenger safety in various driving situations through their design and performance. However, relying solely on the seat design is insufficient. The vehicle's overall structure and collision energy absorption design also significantly impact passenger safety, especially for rear passengers. In frontal, side, and rear-end collisions, the vehicle's cushioning capacity and energy dispersion mechanisms determine the magnitude of the impact force transmitted to the passengers, thus affecting the severity of the accident.

[0004] Existing rear seat anchor point designs often overlook the crucial factor of the vehicle's overall cushioning and energy dissipation capabilities. This limitation of design philosophy makes it impossible to comprehensively guarantee the vehicle's overall safety under various collision scenarios. In particular, existing rear seat safety designs are especially inadequate in common accident types such as frontal, side, and rear-end collisions.

[0005] Therefore, there is an urgent need in the field of automotive safety to develop a new type of rear seat restraint system to address the aforementioned shortcomings. Summary of the Invention

[0006] To address or partially address the problems existing in related technologies, the present invention aims to provide a rear seat anchor point reinforced structure and vehicle that fully considers the overall performance of the vehicle under different collision conditions, effectively integrating seat design with the vehicle body structure to maximize passenger safety. This innovative design not only focuses on the strength and stability of the seat itself, but also coordinates with the vehicle's overall collision energy absorption mechanism, thereby providing comprehensive protection for passengers under various collision conditions.

[0007] To achieve the above objectives, the present invention provides a rear seat fixing point reinforcement structure, including a rear seat front crossbeam assembly, a rear floor middle crossbeam, and a rear seat lower crossbeam assembly arranged in parallel. The rear seat front crossbeam assembly and the rear floor middle crossbeam are connected to each other through a middle row seat mounting bracket. The rear floor middle crossbeam and the rear seat lower crossbeam assembly are connected to each other through a rear floor longitudinal beam welding assembly. The middle row seat mounting bracket and the rear seat front crossbeam assembly are arranged perpendicular to each other, and the rear floor longitudinal beam welding assembly and the rear seat front crossbeam assembly are arranged perpendicular to each other.

[0008] In some embodiments of the present invention, a plurality of middle row seat mounting brackets are provided between the rear seat front crossbeam assembly and the rear floor middle crossbeam, and the plurality of middle row seat mounting brackets are arranged at non-equidistant intervals.

[0009] In some embodiments of the present invention, the two ends of the rear seat front crossbeam assembly are provided with a left rear longitudinal beam seat crossbeam connecting plate and a right rear longitudinal beam seat crossbeam connecting plate, and the middle part of the rear seat front crossbeam assembly is provided with a rear floor front reinforcing plate, a rear foot pedal left reinforcing connecting plate and a rear foot pedal right reinforcing connecting plate arranged perpendicularly thereto.

[0010] In some embodiments of the present invention, the middle row seat mounting bracket is simultaneously fixed to the rear seat front crossbeam assembly and the rear floor front reinforcement plate.

[0011] In some embodiments of the present invention, the middle row seat mounting bracket is provided with a second middle row seat bracket, and the second middle row seat bracket is provided with welding nuts for mounting the seat.

[0012] In some embodiments of the present invention, the two ends of the rear seat underbeam assembly are connected to the rear floor right reinforcement plate assembly and the rear floor left reinforcement plate assembly, the rear seat underbeam assembly is connected to the rear frame seat belt reinforcement beam assembly, the front ends of the rear floor right reinforcement plate assembly and the rear floor left reinforcement plate assembly are connected to the rear wheel arch, and the rear ends of the rear floor right reinforcement plate assembly and the rear floor left reinforcement plate assembly are connected to the rear seat underbeam assembly.

[0013] In some embodiments of the present invention, both the rear floor right reinforcement plate assembly and the rear floor left reinforcement plate assembly include a rear floor reinforcement plate, a rear seat crossbeam front mounting plate, and a nut. The rear floor reinforcement plate is fixed to the outer side of the rear seat lower crossbeam of the rear seat lower crossbeam assembly, and the rear seat crossbeam front mounting plate is fixed to the inner side of the rear seat lower crossbeam of the rear seat lower crossbeam assembly. A nut is provided on the rear seat crossbeam front mounting plate.

[0014] In some embodiments of the present invention, the rear seat underbeam assembly and the rear frame seat belt reinforcing beam assembly form a cavity.

[0015] In some embodiments of the present invention, the left rear longitudinal beam seat crossbeam connecting plate and the right rear longitudinal beam seat crossbeam connecting plate are connected to the left and right door sill beams.

[0016] The present invention also discloses a vehicle including a rear seat anchorage reinforcement structure.

[0017] The advantages of this invention are: the enhanced rear seat anchoring structure not only solves the problem of neglecting the overall vehicle cushioning and energy distribution capabilities in existing technologies, but also achieves optimized integration of the seat anchoring system with the vehicle body structure through its innovative design. This design improves vehicle safety while providing new ideas and directions for the automotive industry in the field of safety design. By enhancing the overall strength and rigidity of the vehicle body and optimizing the force transmission path, this invention significantly improves the overall vehicle safety performance, providing passengers with a safer and more reliable riding experience.

[0018] First, the structure, through the meticulous design and arrangement of three crossbeams (the front crossbeam assembly of the rear seats, the middle crossbeam of the rear floor, and the lower crossbeam assembly of the rear seats) and two longitudinal beams (the welded longitudinal beam assembly of the rear floor), forms a highly integrated and mutually supporting overall frame. This innovative design not only enhances the fixation strength of the rear seats but also significantly improves the energy absorption and dispersion capabilities of the entire vehicle structure under various collision conditions. In particular, the mounting points of the rear seats cleverly distribute the force to these three crossbeams and two longitudinal beams through reinforcing plates and connecting plates, making the seats more secure and reliable. This force dispersion mechanism is particularly prominent in frontal, side, and rear-end collisions, greatly enhancing the vehicle's buffering and energy dispersion capabilities, thereby more effectively protecting rear passengers and significantly improving the overall safety of the vehicle.

[0019] Secondly, the non-equidistant spacing of the middle row seat mounting brackets, along with their dual connection to the rear seat front crossbeam assembly and the rear floor front reinforcement plate, further optimizes the force transmission and dispersion path. This design not only enhances the stability of the middle row seats but also improves the collaborative working ability of the entire seating system during a collision, allowing the impact force to be distributed more evenly throughout the vehicle structure. Simultaneously, the interconnection of the crossbeams and longitudinal beams significantly enhances the overall strength and rigidity of the vehicle body, providing passengers with a safer riding environment.

[0020] Furthermore, the cavity structure formed by the rear seat under-beam assembly and the rear frame seatbelt reinforcement beam assembly, along with the design of the right and left rear floor reinforcement plates, further enhances the structural rigidity of the rear area. This not only improves the safety of rear passengers but also optimizes the seatbelt anchorage design, ensuring that the seatbelts function more effectively in a collision, providing comprehensive protection for passengers.

[0021] Finally, the overall structural design fully considers its coordination with other vehicle body components, such as the connection of the left and right sill beams and the integration of the rear wheel arches. This comprehensive system design approach ensures that, in the event of a collision, the vehicle can absorb and disperse impact energy in a more coordinated and efficient manner, thereby maximizing the safety of all passengers.

Detailed Implementation

[0031] The technical solutions (including preferred technical solutions) of the present invention will be further described in detail below with reference to the accompanying drawings and by way of listing some optional embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] This invention provides a reinforced structure for rear seat anchor points, which significantly improves the safety and stability of the rear seats through innovative design and layout. The specific embodiments of this invention will now be described in detail with reference to the accompanying drawings.

[0033] like Figure 1 As shown, the rear seat fixing point reinforcement structure of the present invention mainly includes three sets of crossbeam structures. These three sets of crossbeams form a highly integrated and mutually supportive overall frame through a clever connection method. Specifically, the structure includes the following main components: left mounting bracket 1 for the middle row seat, left rear longitudinal beam seat crossbeam connecting plate 2, front crossbeam assembly for the rear seat 3, front reinforcing plate for the rear floor 4, left reinforcing connecting plate for the rear footrest 5, right reinforcing connecting plate for the rear footrest 6, right rear longitudinal beam seat crossbeam connecting plate 7, middle crossbeam for the rear floor 8, right reinforcing plate assembly for the rear floor 9, lower crossbeam assembly for the rear seat 10, welded assembly of the rear floor longitudinal beam 11, seat belt reinforcing crossbeam assembly for the rear frame 13, and left reinforcing plate assembly for the rear floor 14.

[0034] The first crossbeam assembly consists of the left rear longitudinal beam seat crossbeam connecting plate 2, the rear seat front crossbeam assembly 3, and the right rear longitudinal beam seat crossbeam connecting plate 7. Together, they connect the left and right sill beams, forming an important support for the vehicle body structure. The rear ends of the rear floor front reinforcement plate 4, the rear foot pedal left reinforcement connecting plate 5, and the rear foot pedal right reinforcement connecting plate 6 are connected to the first crossbeam, while their front ends are connected to the front floor assembly. This design enhances the structural connection between the front and rear parts of the vehicle body.

[0035] The second crossbeam consists of the middle crossbeam 8 of the rear floor, which plays a crucial role in the overall structure as a central support. The third crossbeam assembly comprises the right rear floor reinforcement plate assembly 9, the lower crossbeam assembly of the rear seats 10, the rear frame seat belt reinforcement crossbeam assembly 13, and the left rear floor reinforcement plate assembly 14. This combination provides a solid foundation for the rear seats.

[0036] A key feature of this invention is that the first and second crossbeams are connected together by four middle-row seat mounting brackets 1, while the second and third crossbeams are connected together by the rear floor longitudinal beam welding assembly 11. This design not only enhances the rigidity of the overall structure but also effectively distributes the mounting points of the rear seats throughout the structure, thereby better distributing the forces borne by the seats.

[0037] like Figure 2-4As shown, the design of the middle row seat mounting bracket 1 further optimizes the strength and stability of the structure. Specifically, the front end of the middle row seat mounting bracket 1 is connected to the rear seat front crossbeam assembly 3 and the rear floor front reinforcement plate 4, while its rear end is connected to the rear floor middle crossbeam 8. This connection method not only strengthens the connection between the crossbeams but also provides a more stable mounting base for the seats. It is worth noting that the rear floor front reinforcement plate 4 plays an important role in connecting the first crossbeam and the front floor assembly, further enhancing the integrity of the overall structure.

[0038] To enhance the strength of the seat mounting points, this invention welds a second middle-row seat bracket 21 to the front end of the middle-row seat mounting bracket 1, and installs a welding nut 22 on it as a pre-embedded nut for the seat mounting points. This design significantly strengthens the mounting points, ensuring the stability of the seat under various driving conditions. Particularly noteworthy is the presence of four front mounting points, corresponding to four middle-row seat mounting brackets 1, which connect between the first and second crossbeams, further reinforcing the connection strength between the crossbeams.

[0039] like Figure 5-6 As shown, the design of the rear seat area also embodies unique innovation. The left rear floor reinforcement plate 31 is welded together with the lower crossbeam 32 of the rear seat, forming a robust whole. A nut 34 is welded to the left front mounting plate 33 of the rear seat crossbeam, which is welded to the lower end of the lower crossbeam 32 of the rear seat, playing an important reinforcing role. It is worth noting that the front ends of the right rear floor reinforcement plate assembly 9 and the left rear floor reinforcement plate assembly 14 are connected to the rear wheel arch, while the rear ends are connected to the third crossbeam group. This design not only enhances the structural strength of the rear area but also optimizes the force transmission path.

[0040] like Figure 7 As shown, this invention also demonstrates unique innovation in the design of the rear seat under-beam assembly 10 and the rear frame seatbelt reinforcing beam assembly 13. These two components are welded together, forming a cavity in the middle. This beam-like structural design significantly enhances the overall strength of the vehicle body, providing better protection, especially in side collisions. The design of the rear floor longitudinal beam welded assembly 11 further strengthens the connection between the second and third beam groups, ensuring the stability and rigidity of the entire structure.

[0041] Another important feature of this invention is that multiple middle row seat mounting brackets 1 are provided between the rear seat front crossbeam assembly 3 and the rear floor middle crossbeam 8. These brackets are arranged in a non-equidistant manner. This design not only increases the complexity of the structure but also optimizes the force distribution, enabling the entire structure to exhibit excellent performance when facing impacts from different directions.

[0042] At both ends of the rear seat front crossbeam assembly 3, the present invention provides a left rear longitudinal beam seat crossbeam connecting plate 2 and a right rear longitudinal beam seat crossbeam connecting plate 7. These two connecting plates are connected to the left and right sill beams, further enhancing the connection between the entire structure and other parts of the vehicle body. In the middle of the rear seat front crossbeam assembly 3, a rear floor front reinforcing plate 4, a rear footrest left reinforcing connecting plate 5, and a rear footrest right reinforcing connecting plate 6 are arranged perpendicularly thereto. This design not only enhances the strength of the crossbeam itself but also provides additional support points, which is beneficial for the distribution and transmission of forces.

[0043] The middle row seat mounting bracket 1 is simultaneously fixed to the rear seat front crossbeam assembly 3 and the rear floor front reinforcement plate 4. This multi-point fixing design significantly increases the stability and rigidity of the entire structure, especially in the event of a collision, providing better protection for passengers.

[0044] The present invention also demonstrates unique innovation in the design of the rear seat under-beam assembly 10. The two ends of the rear seat under-beam assembly 10 are respectively connected to the right rear floor reinforcement plate assembly 9 and the left rear floor reinforcement plate assembly 14. This design not only enhances the strength of the beam but also optimizes the force transmission path. Simultaneously, the rear seat under-beam assembly 10 is also connected to the rear frame seatbelt reinforcement beam assembly 13, and these two components together form a cavity 12. This cavity design not only reduces structural weight but also increases the structure's torsional resistance.

[0045] The rear seat anchor point enhancement structure of this invention, through innovative design and ingenious layout, achieves optimized distribution of rear seat mounting points, significantly enhancing vehicle safety performance under various collision conditions. This design not only improves the stability and safety of the rear seats but also enhances the rigidity and strength of the entire vehicle body structure, providing passengers with a safer and more comfortable riding experience.

[0046] It will be readily understood by those skilled in the art that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, combinations, substitutions, improvements, etc., made under the spirit and principles of the present invention are included within the protection scope of the present invention.
