[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0024] This utility model provides a seatbelt body reinforcement structure. The design focuses on a three-row seatbelt configuration, but is not limited to three rows. This reinforcement structure is located on the upper part of the D-pillar and consists of a D-pillar reinforcement plate 5, an inner D-pillar plate 3, a three-row seatbelt reinforcement plate 4, and a three-row seatbelt mounting plate 6. This three-row seatbelt body reinforcement structure must meet the regulatory requirements for seatbelt anchor point stiffness. The three-row seatbelt body reinforcement structure designed in this utility model is compact, meets process requirements, and also achieves lightweight body design.

[0025] Figure 1 The diagram shows the installation position of the three-row seat belts. As can be seen from the diagram, the three-row seat belt assembly 2 is located at the D-pillar position on the rear side of the vehicle. The main structure includes the side panel assembly 1 and the three-row seat belt assembly 2 located at the D-pillar position on the rear side of the vehicle. The side panel assembly 1 includes the inner panel 3 on the D-pillar. The mounting points of the three-row seat belts of the three-row seat belt assembly 2 are located on the inner panel 3 on the D-pillar of the side panel assembly 1. The three-row seat belt assembly 2 is installed on the inner panel 3 on the D-pillar through the mounting points. In this embodiment, the inner panel 3 on the D-pillar is preferably a one-piece bent part.

[0026] Figure 2 The diagram shows a cross-sectional view of the three-row seatbelt installation. As can be seen, the three-row seatbelt assembly 2 is mounted on the three-row seatbelt mounting nuts 8 below the side panel assembly 1 via three-row seatbelt mounting bolts 7. The side panel assembly 1 also includes a support assembly connected to the inner panel 3 on the D-pillar. The support assembly includes a three-row seatbelt reinforcing plate 4, a three-row seatbelt mounting plate 6, and three-row seatbelt mounting nuts 8. The three-row seatbelt mounting nuts 8 are pre-connected to the three-row seatbelt mounting plate 6 to form a three-row seatbelt mounting plate assembly. This assembly is then connected to the three-row seatbelt reinforcing plate 4 to form the support assembly. In actual manufacturing, the three-row seatbelt reinforcing plate 4 is preferably a one-piece bent component. The connection between the three-row seatbelt reinforcing plate 4, the three-row seatbelt mounting plate 6, and the three-row seatbelt mounting nuts 8 is preferably a rigid connection via welding to ensure proper installation of the three-row seatbelts. After welding, the three components are joined to the inner panel 3 on the D-pillar, forming a localized reinforcement structure for the three rows of seat belts, ensuring the rigidity of the seat belt mounting points. Finally, this assembly is welded to the D-pillar reinforcement plate 5 to form a closed cavity, guaranteeing the overall performance of the vehicle body.

[0027] The outer contour of the three-row seat belt mounting plate 6 is larger than that of the three-row seat belt mounting nut 8, and the three-row seat belt mounting plate 6 has a hole diameter not smaller than that of the three-row seat belt mounting nut 8. The three-row seat belt assembly 2 is installed on the three-row seat belt mounting nut 8 of the side assembly 1 through the three-row seat belt mounting bolt 7. The side assembly 1 also includes a D-pillar reinforcing plate 5 connected to the upper inner panel 3 of the D-pillar. Both the D-pillar reinforcing plate 5 and the upper inner panel 3 of the D-pillar are L-shaped bent parts, and the two are interlocked to form a closed cavity with a hollow structure inside, which improves the overall fixation and reinforcement performance of the vehicle body.

[0028] Figure 3 The diagram shown is a CAE performance analysis diagram of the three-row seat belt. The CAE analysis results show that the three-row seat belt body reinforcement structure designed in this utility model meets the stress and strain requirements of the fixed points on the three-row seat belt, and the simulation results are qualified.

[0029] Figure 4 The diagram shows a three-row seatbelt vehicle body structure (with D-pillar reinforcement plate 5). As can be seen from the diagram, the D-pillar reinforcement plate 5 is an integral reinforcement beam structure from top to bottom. The upper side of the D-pillar reinforcement plate 5 is connected to the rear crossbeam 9 of the roof, and the lower side is connected to the floor beam (not shown in this diagram because it is far from the D-pillar reinforcement plate 5). The D-pillar position forms a ring structure, which ensures the overall rigidity of the vehicle body and also meets the local rigidity requirements of the three-row seatbelt installation points.

[0030] Figure 5 The diagram shown is a schematic of a three-row seatbelt vehicle body structure (with the D-pillar reinforcement plate 5 hidden). This schematic diagram is based on... Figure 2 Supplementary explanation of the schematic diagram of the three-row seat belt installation cross-section. This schematic diagram more clearly shows that the three-row seat belt mounting nuts 8 and the three-row seat belt mounting plate 6 are pre-welded together to form the three-row seat belt mounting plate assembly; the three-row seat belt mounting plate assembly and the three-row seat belt reinforcing plate 4 are welded together to meet the rigidity requirements of the three-row seat belt installation point; simultaneously, the three-row seat belt reinforcing plate 4 is welded to the inner plate 3 on the D-pillar to improve the overall rigidity of the D-pillar joint position; finally, a D-pillar reinforcing plate 5 is added to the outside to form a closed cavity, meeting the performance requirements of the three-row seat belt.

[0031] A vehicle with 7 seats is also proposed, including the aforementioned seat belt body reinforcement structure. The seat belt reinforcement structure in this design is designed to be as simple as possible, with minimal increase in weight, while meeting the stiffness requirements of the seat belt mounting points for all three rows of seats, ultimately ensuring the safety of passengers in all three rows.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
