Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a rear seat fixing point reinforced structure, a high-voltage distribution box and a vehicle. Background Art

[0002] With the booming development of the automobile industry and the continuous improvement of people's material living standards, cars have evolved from luxury goods in the past to an indispensable daily necessity in modern society. In this context, the importance of automobile safety has become increasingly prominent and has become the primary consideration in the automobile design and manufacturing process.

[0003] As a basic configuration to ensure the safety of passengers, the design and performance of car seats are directly related to the personal safety of passengers in various driving situations. However, relying solely on the design of the seat itself is not enough. The overall structure and collision energy absorption design of the vehicle also have a significant impact on the safety of passengers, especially rear passengers. In the event of a frontal, side and rear-end collision, the vehicle's buffering capacity and energy dispersion mechanism determine the magnitude of the impact force transmitted to the passengers, thereby affecting the severity of the accident.

[0004] The existing rear seat fixing point design often ignores the key factor of the vehicle's overall buffering and energy dispersion capabilities. The limitations of this design concept make it impossible to fully guarantee the overall safety of the vehicle in various collision situations. In particular, in common accident types such as frontal, side and rear-end collisions, the existing rear seat safety design is particularly insufficient.

[0005] In view of this, the automotive safety field urgently needs to develop a new rear seat fixing system to solve the above-mentioned defects. Summary of the invention

[0006] In order to solve or partially solve the problems existing in the related art, the purpose of the present invention is to provide a rear seat fixing point enhanced structure and vehicle, which can fully consider the overall performance of the vehicle under different collision conditions, effectively integrate the seat design and the body structure, so as to maximize the safety of passengers. This innovative design should not only focus on the strength and stability of the seat itself, but also coordinate with the overall collision energy absorption mechanism of the vehicle, so as to provide all-round protection for passengers in various collision conditions.

[0007] To achieve the above-mentioned purpose, the present invention provides a rear seat fixing point enhanced structure, including a rear seat front cross beam assembly, a rear floor middle cross beam and a rear seat lower cross beam assembly arranged in parallel, the rear seat front cross beam assembly and the rear floor middle cross beam are connected to each other through a middle row seat mounting bracket, the rear floor middle cross beam and the rear seat lower cross beam 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 cross beam assembly are arranged perpendicular to each other, and the rear floor longitudinal beam welding assembly and the rear seat front cross beam 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 cross beam assembly and the rear floor middle cross beam, and the plurality of middle row seat mounting brackets are arranged at non-equidistant intervals.

[0009] In some embodiments of the present invention, a left rear longitudinal beam seat cross beam connecting plate and a right rear longitudinal beam seat cross beam connecting plate are provided at both ends of the rear seat front cross beam assembly, and a rear floor front reinforcement plate, a rear footrest left reinforcement connecting plate and a rear footrest right reinforcement connecting plate arranged vertically therewith are provided in the middle portion of the rear seat front cross beam assembly.

[0010] In some embodiments of the present invention, the middle row seat mounting bracket is fixedly connected to the rear seat front cross beam assembly and the rear floor front reinforcement plate at the same time.

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

[0012] In some embodiments of the present invention, both ends of the rear seat lower cross beam assembly are connected to the rear floor right reinforcement plate assembly and the rear floor left reinforcement plate assembly, the rear seat lower cross beam assembly is connected to the rear skeleton seat belt reinforcement cross 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 housing, 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 lower cross beam assembly.

[0013] In some embodiments of the present invention, the rear floor right reinforcement plate assembly and the rear floor left reinforcement plate assembly both include a rear floor reinforcement plate, a rear seat cross beam front mounting plate and nuts, the rear floor reinforcement plate is fixedly connected to the outer side of the rear seat lower cross beam of the rear seat lower cross beam assembly, the rear seat cross beam front mounting plate is fixedly connected to the inner side of the rear seat lower cross beam of the rear seat lower cross beam assembly, and nuts are arranged on the rear seat cross beam front mounting plate.

[0014] In some embodiments of the present invention, the rear seat lower cross beam assembly and the rear frame safety belt reinforcement cross beam assembly enclose a cavity.

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

[0016] The invention also discloses a vehicle, comprising the rear seat fixing point enhanced structure claimed.

[0017] The beneficial effect of the present invention is that the rear seat fixing point enhanced structure of the present invention not only solves the problem of neglecting the overall buffering and energy dispersion capabilities of the vehicle in the prior art, but also realizes the optimized integration of the seat fixing system and the vehicle body structure through its innovative design. This design not only improves the safety of the vehicle, but also provides new ideas and directions for the automotive manufacturing industry in the field of safety design. By enhancing the overall strength and rigidity of the vehicle body and optimizing the force transmission path, the present invention significantly improves the safety performance of the entire vehicle and provides passengers with a safer and more reliable riding experience.

[0018] First, the structure forms a highly integrated and mutually supporting overall frame through the careful 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 welding assembly of the longitudinal beams of the rear floor). This innovative design not only enhances the fixing strength of the rear seats, but also significantly improves the energy absorption and dispersion capabilities of the entire body structure in various collision situations. In particular, the mounting points of the rear seats cleverly disperse the forces to these three crossbeams and two longitudinal beams through reinforcement plates and connecting plates, making the seat fixing more firm 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 and the dual fixed connection with the rear seat front crossbeam assembly and the rear floor front reinforcement plate further optimize 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 seat system during a collision, so that the impact force can be more evenly distributed to the body structure. At the same time, the interconnection of the crossbeam and the longitudinal beam greatly enhances the overall strength and rigidity of the body, providing a safer riding environment for passengers.

[0020] Furthermore, the cavity structure formed by the rear seat lower crossbeam assembly and the rear frame seat belt reinforcement crossbeam assembly, as well as the design of the rear floor right reinforcement plate assembly and the rear floor left reinforcement plate assembly, further enhance the structural rigidity of the rear area. This not only improves the safety of rear passengers, but also optimizes the design of the seat belt fixing points, ensuring that the seat belt can play a more effective role in a collision, providing all-round protection for passengers.

[0021] Finally, the design of the entire structure fully considers the coordination with other body parts, such as the connection of the left and right rocker beams, the integration of the rear wheel cover, etc. This comprehensive system design approach ensures that when a collision occurs, the vehicle can absorb and disperse the impact energy in a more coordinated and efficient way, thereby maximizing the safety of all passengers.

DETAILED DESCRIPTION

[0031] The technical solution of the present invention (including the preferred technical solution) is further described in detail below by means of the accompanying drawings and by listing some optional embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The present invention provides a rear seat fixing point enhanced structure, which significantly improves the safety and stability of the rear seats of the vehicle through innovative design and layout. The specific implementation of the present invention will be described in detail below with reference to the accompanying drawings.

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

[0034] The first crossbeam group is composed 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, which together connect the left and right door sill beams to form an important support for the vehicle body structure. The rear ends of the rear floor front reinforcement plate 4, the rear footrest left reinforcement connecting plate 5 and the rear footrest right reinforcement connecting plate 6 are connected to the first crossbeam, while their front ends are connected to the front floor group. This design strengthens the structural connection between the front and rear parts of the vehicle body.

[0035] The second crossbeam is composed of the rear floor middle crossbeam 8, which plays a key role in the middle support of the entire structure. The third crossbeam group is composed of the rear floor right reinforcement plate assembly 9, the rear seat lower crossbeam assembly 10, the rear frame safety belt reinforcement crossbeam assembly 13 and the rear floor left reinforcement plate assembly 14, which provide a solid basic support for the rear seats.

[0036] An important feature of the present invention is that the first cross beam and the second cross beam are connected together by four middle row seat mounting brackets 1, and the second cross beam and the third cross beam 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 disperses the mounting points of the rear row seats throughout the structure, thereby better dispersing 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 cross beam assembly 3 and the rear floor front reinforcement plate 4, while its rear end is connected to the rear floor middle cross beam 8. This connection method not only strengthens the connection between the cross beams, but also provides a more stable installation foundation for the seats. It is worth noting that the rear floor front reinforcement plate 4 plays an important role in connecting the first cross beam and the front floor assembly, further enhancing the integrity of the overall structure.

[0038] In order to improve the strength of the seat mounting point, the present invention welds the middle row seat second bracket 21 at the front end of the middle row seat mounting bracket 1, and sets a welding nut 22 thereon as a pre-embedded nut for the seat mounting point. This design significantly enhances the strength of the mounting point and ensures the stability of the seat under various driving conditions. It is particularly worth mentioning that there are 4 front mounting points, corresponding to 4 middle row seat mounting brackets 1, which are connected between the first crossbeam and the second crossbeam, further strengthening the connection strength between the crossbeams.

[0039] like Figure 5-6 As shown, the present invention also embodies unique innovation in the design of the rear seat area. The rear floor left reinforcement plate 31 is welded to the rear seat lower cross beam 32 to form a solid whole. A nut 34 is welded to the left front mounting plate 33 of the rear seat cross beam. This nut 34 is welded to the lower end of the rear seat lower cross beam 32 and plays an important reinforcing role. It is worth noting that the front ends of the rear floor right reinforcement plate assembly 9 and the rear floor left reinforcement plate assembly 14 are connected to the rear wheel cover, and the rear ends are connected to the third cross beam 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, the present invention also shows unique innovation in the design of the rear seat lower cross beam assembly 10 and the rear frame safety belt reinforcement cross beam assembly 13. These two components are welded together to form a cavity in the middle. This beam structure design significantly enhances the overall strength of the vehicle body, especially in side collisions, and can provide better protection. The design of the rear floor longitudinal beam welding assembly 11 further strengthens the connection between the second cross beam and the third cross beam group, ensuring the stability and rigidity of the entire structure.

[0041] Another important feature of the present invention is that a plurality of middle row seat mounting brackets 1 are arranged between the rear seat front cross beam assembly 3 and the rear floor middle cross beam 8, and these brackets are arranged at non-equidistant intervals. This design not only increases the complexity of the structure, but also optimizes the distribution of force, so that the entire structure can show excellent performance when facing impacts from different directions.

[0042] At both ends of the rear seat front cross beam assembly 3, the present invention is provided with a left rear longitudinal beam seat cross beam connecting plate 2 and a right rear longitudinal beam seat cross beam connecting plate 7. These two connecting plates are connected to the left and right door sill beams, further strengthening the connection between the entire structure and other parts of the vehicle body. In the middle of the rear seat front cross beam assembly 3, a rear floor front reinforcement plate 4, a rear footrest left reinforcement connecting plate 5 and a rear footrest right reinforcement connecting plate 6 are arranged vertically therewith. This design not only enhances the strength of the cross beam itself, but also provides additional support points, which is conducive to the dispersion and transmission of force.

[0043] The middle row seat mounting bracket 1 is fixedly connected to the rear seat front cross beam assembly 3 and the rear floor front reinforcement plate 4. This multi-point fixed design significantly increases the stability and rigidity of the entire structure, especially in the event of a collision, which can better protect passengers.

[0044] The present invention also demonstrates unique innovation in the design of the rear seat lower cross beam assembly 10. The two ends of the rear seat lower cross beam assembly 10 are respectively connected to the rear floor right reinforcement plate assembly 9 and the rear floor left reinforcement plate assembly 14. This design not only enhances the strength of the cross beam, but also optimizes the force transmission path. At the same time, the rear seat lower cross beam assembly 10 is also connected to the rear frame seat belt reinforcement cross beam assembly 13, and these two components together form a cavity 12. This cavity design not only reduces the weight of the structure, but also increases the anti-torsion ability of the structure.

[0045] The rear seat fixing point enhanced structure of the present invention realizes the optimized distribution of rear seat installation points through innovative design and ingenious layout, significantly enhancing the safety performance of the vehicle in various collision situations. 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] Those skilled in the art will readily appreciate that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, combinations, replacements, improvements, etc. made within the spirit and principles of the present invention are included within the protection scope of the present invention.
