[0036] The first embodiment of the present invention provides a seat - belt mounting structure, which is disposed on the D - pillar 100 of a vehicle. In the present invention, as Figures 1-3 shown, the vehicle D - pillar 100 includes a D - pillar inner panel and a D - pillar reinforcement panel. The D - pillar reinforcement panel is disposed outside the D - pillar inner panel and is connected to the D - pillar inner panel. The D - pillar inner panel includes a D - pillar inner panel upper section 101 and a D - pillar inner panel lower section 102 which are connected to each other. The D - pillar reinforcement panel includes a D - pillar reinforcement panel upper section 103 and a D - pillar reinforcement panel lower section 104. Among them, the D - pillar reinforcement panel upper section 103 corresponds to the D - pillar inner panel upper section 101, and the D - pillar reinforcement panel lower section 104 is connected to the D - pillar inner panel lower section 102.

[0037] In some embodiments, as Figure 2As shown, since one end of the upper section 101 of the D-pillar inner panel is connected to the lower section 102 of the D-pillar inner panel, the strength at the connection between the two is weak. An outer side of the connection between the upper section 101 and the lower section 102 of the D-pillar inner panel is provided with a D-pillar inner panel reinforcement plate 105 to reinforce the connection between the upper section 101 and the lower section 102 of the D-pillar inner panel. Among them, the D-pillar inner panel reinforcement plate 105 is a plate-shaped component, and it has a sufficient contact area with the connection between the upper section 101 and the lower section 102 of the D-pillar inner panel to improve the strength of this connection.

[0038] The first embodiment of the present utility model provides a seat belt mounting structure, as Figures 1-9 shown. This seat belt mounting structure is used to mount the first seat belt 200, the second seat belt 300, the first retractor 400, and the second retractor 500. The seat belt mounting structure includes an upper mounting plate 1 for the first seat belt, a lower mounting plate 2 for the first seat belt, an upper mounting plate 3 for the first retractor, and a lower mounting plate 4 for the first retractor. The upper mounting plate 3 and the lower mounting plate 4 for the first retractor are provided on the lower section 102 of the D-pillar inner panel. The upper mounting plate 1 for the first seat belt is mounted on the inner side of the upper section 101 of the D-pillar inner panel. The lower mounting plate 2 for the first seat belt is mounted on the inner side of the lower section 102 of the D-pillar inner panel and is respectively connected to the upper mounting plate 3 and the lower mounting plate 4 for the first retractor. One end of the first seat belt 200 is connected to the upper mounting plate 1 for the first seat belt, and the other end of the first seat belt 200 passes through the lower mounting plate 2 for the first seat belt and is connected to the first retractor 400.

[0039] Among them, the mounting positions of the first seat belt 200 are set at different positions on the D-pillar inner panel, so that the force can be dispersed when the first seat belt 200 is tensioned. Specifically, the upper mounting plate 1 for the first seat belt and the lower mounting plate 2 for the first seat belt are respectively provided on the upper section 101 and the lower section 102 of the D-pillar inner panel. When the first seat belt 200 is tensioned, the force is respectively transmitted to the upper section 101 and the lower section 102 of the D-pillar inner panel, enabling the D-pillar inner panel to be evenly stressed and improving the anti-deformation ability of the D-pillar inner panel. Both ends of the lower mounting plate 2 for the first seat belt are respectively connected to the upper mounting plate 3 and the lower mounting plate 4 for the first retractor. The upper mounting plate 3 and the lower mounting plate 4 for the first retractor support the lower mounting plate 2 for the first seat belt to improve the structural strength of the lower mounting plate 2 for the first seat belt. To improve the strength at the mounting position of the first seat belt 200, the upper mounting plate 1 for the first seat belt is provided in a conical shape.

[0040] The seat belt mounting structure further includes an upper reinforcement plate 5 of the first retractor and a lower reinforcement plate 6 of the first retractor. The upper mounting plate 3 of the first retractor is installed on the inner side of the lower section 102 of the D-pillar inner panel. The upper reinforcement plate 5 of the first retractor is installed on the outer side of the lower section 102 of the D-pillar inner panel and corresponds to the upper mounting plate 3 of the first retractor. The lower mounting plate 4 of the first retractor is installed on the inner side of the lower section 102 of the D-pillar inner panel. The lower reinforcement plate 6 of the first retractor is installed on the outer side of the lower section 102 of the D-pillar inner panel and at least partially extends toward the inner side of the lower section 102 of the D-pillar inner panel to be connected to the lower mounting plate 4 of the first retractor.

[0041] Among them, the upper mounting plate 3 of the first retractor is arranged on the inner side of the lower section 102 of the D-pillar inner panel. The position of the upper reinforcement plate 5 of the first retractor on the outer side of the lower section 102 of the D-pillar inner panel corresponds to the position of the upper mounting plate 3 of the first retractor. The upper reinforcement plate 5 of the first retractor locally strengthens the position of the upper mounting plate 3 of the first retractor. A part of the lower reinforcement plate 6 of the first retractor is arranged on the outer side of the lower section 102 of the D-pillar inner panel, and another part of the lower reinforcement plate 6 of the first retractor is arranged on the inner side of the lower section 102 of the D-pillar inner panel and is connected to the lower mounting plate 4 of the first retractor. The lower mounting plate 4 of the first retractor and the lower reinforcement plate 6 of the first retractor support each other, increasing the overall strength of the lower mounting plate 4 of the first retractor and the lower reinforcement plate 6 of the first retractor, strengthening the structural strength of the lower section 102 of the D-pillar inner panel, improving the support performance for the first retractor 400, and enhancing the ability of the lower mounting plate 4 of the first retractor to resist tensile deformation.

[0042] Specifically, as Figures 4-7As shown, a first mounting opening 1021 is formed in the lower section 102 of the D-pillar inner panel. The lower mounting plate 4 of the first retractor includes a first tapered portion 41 and a first flanging 42. The first tapered portion 41 is arranged in a conical shape and extends towards the interior of the vehicle and is connected to the first retractor 400. The first flanging 42 is connected to the edge of the first mounting opening 1021. Among them, the first tapered portion 41 is arranged inside the lower section 102 of the D-pillar inner panel, providing a mounting position for the lower mounting plate 2 of the first seat belt and supporting the lower mounting plate 2 of the first seat belt. The first flanging 42 is arranged outside the lower section 102 of the D-pillar inner panel, and the first tapered portion 41 is arranged as a cone, such as a circular cone or a pyramid. The connection stability between the first tapered portion 41 and the lower section 102 of the D-pillar inner panel is stronger. The first flanging 42 has a larger contact area with the lower section 102 of the D-pillar inner panel, improving the connection reliability between the lower mounting plate 4 of the first retractor and the lower section 102 of the D-pillar inner panel. The lower reinforcing plate 6 of the first retractor includes a reinforcing plate portion 61 and a second tapered portion 62. The reinforcing plate portion 61 is connected to the outside of the lower section 102 of the D-pillar inner panel. The second tapered portion 62 is arranged in a conical shape and passes through the first mounting opening 1021 to be connected to the first tapered portion 41. Among them, the second tapered portion 62 is arranged inside the lower section 102 of the D-pillar inner panel, and the reinforcing plate portion 61 is arranged outside the lower section 102 of the D-pillar inner panel. The second tapered portion 62 and the first tapered portion 41 are connected inside the lower section 102 of the D-pillar inner panel. Both the second tapered portion 62 and the first tapered portion 41 are arranged in a conical shape, such as a circular cone or a pyramid, which can ensure that they have greater strength. The lower mounting plate 4 of the first retractor and the lower reinforcing plate 6 of the first retractor are still connected to form a tapered reinforcing structure, and the two reinforce each other, increasing the strength of the tapered reinforcing structure.

[0043] Among them, an installation space for avoiding the first retractor 400 is formed after the second tapered portion 62 and the first tapered portion 41 are butted.

[0044] In some embodiments, the upper mounting plate 3 of the first retractor includes a mounting portion 31 extending towards the interior of the vehicle and a second flanging 32 connected to the lower section 102 of the D-pillar inner panel. The mounting portion 31 is arranged in a conical shape. The upper reinforcing plate 5 of the first retractor is arranged in a "Z" shape, and the upper reinforcing plate 5 of the first retractor has a third flanging 51 connected to the lower section 102 of the D-pillar inner panel. Among them, the mounting portion 31 is arranged as a cone to ensure the strength of the mounting portion 31 and the connection strength between it and the lower section 102 of the D-pillar inner panel through the second flanging 32. Exemplarily, the mounting portion 31 is arranged as a circular cone or a pyramid. Specifically, to ensure the reliable installation of the mounting portion 31, the upper reinforcing plate 5 of the first retractor is arranged in a "Z" shape, and there are multiple second flangings 32. One of the second flangings 32, the lower section 102 of the D-pillar inner panel, and the third flanging 51 are sequentially stacked and connected. The above three reinforce each other, improving the structural strength of the upper mounting plate 3 of the first retractor and also enhancing the structural strength of the corresponding position of the lower section 102 of the D-pillar inner panel. Exemplarily, there are 3 second flangings 32.

[0045] When a collision occurs, such as Figure 6 and 7 shown, the first seat belt 200 is tensioned, and the first retractor 400 is accordingly tensioned. The lower mounting plate 4 of the first retractor is subjected to an upward pulling force, and the lower reinforcement plate 6 of the first retractor gives a certain pushing force to the lower mounting plate 4 of the first retractor, playing a supporting role and improving the anti-deformation ability of the lower mounting plate 4 of the first retractor. In this way, the pulling force of the first seat belt 200 is dispersed to the lower section 102 of the D-pillar inner panel through the lower mounting plate 4 of the first retractor and the lower reinforcement plate 6 of the first retractor. The upward pushing force of the first retractor 400 is transmitted to the lower section 102 of the D-pillar inner panel through the upper mounting plate 3 of the first retractor, and then transmitted to the upper section 101 of the D-pillar inner panel, etc., to achieve force dispersion, avoid deformation of the lower section 102 of the D-pillar inner panel, and prevent deformation of the upper mounting plate 3 of the first retractor.

[0046] In some embodiments, such as Figure 1 and 8 shown, the top of the upper section 101 of the D-pillar inner panel is connected to the rear cross member 600 of the roof. The seat belt mounting structure further includes a second upper seat belt mounting plate 7, a second lower seat belt mounting plate 8, and a second retractor mounting plate 9. The second upper seat belt mounting plate 7 is mounted on the inner side of the rear cross member 600 of the roof. The second lower seat belt mounting plate 8 and the second retractor mounting plate 9 are mounted on the upper section 101 of the D-pillar inner panel. The second lower seat belt mounting plate 8 is connected to the second retractor mounting plate 9. The second retractor 500 is mounted on the outer side of the upper section 101 of the D-pillar inner panel through the second retractor mounting plate 9. One end of the second seat belt 300 is connected to the second upper seat belt mounting plate 7, and the other end of the second seat belt 300 passes through the second lower seat belt mounting plate 8 and is connected to the second retractor 500. The second retractor mounting plate 9 is arranged in an L shape, connecting the second retractor mounting plate 9 and the second lower seat belt mounting plate 8 together, which is beneficial to optimizing the space layout.

[0047] Among them, the installation of the second seat belt 300 is respectively arranged at different positions, which can achieve force dispersion when the first seat belt 200 is tensioned. Specifically, the second upper seat belt mounting plate 7 is arranged on the inner side of the rear cross member 600 of the roof, the second lower seat belt mounting plate 8 is arranged on the upper section 101 of the D-pillar inner panel, and the upper section 101 of the D-pillar inner panel is provided with a second installation opening 1011. The second seat belt 300 passes through the second upper seat belt mounting plate 7 and passes through the second installation opening 1011 to be connected to the second lower seat belt mounting plate 8. As Figure 9 shown, when the second seat belt 300 is tensioned, the force is respectively transmitted to the upper section 101 of the D-pillar inner panel and the rear cross member 600 of the roof. After the second lower seat belt mounting plate 8 is connected to the second retractor mounting plate 9 and then connected to the outer side of the upper section 101 of the D-pillar inner panel, the second lower seat belt mounting plate 8 and the second retractor mounting plate 9 support each other to ensure the structural strength.

[0048] As Figure 2 and Figure 8 shown, the rear door stay is usually arranged in the side wall gutter. The side wall gutter is connected to one side surface of the upper section 103 of the D-pillar reinforcement plate. In some embodiments, a rear door stay reinforcement plate 10 is installed on the outer side of the upper section 101 of the D-pillar inner panel. Among them, the rear door stay reinforcement plate 10 supports the rear door stay. The rear door stay reinforcement plate 10 and the upper section 101 of the D-pillar inner panel are connected to form a reinforcement cavity 11, which not only enhances the strength of the rear door stay reinforcement plate 10, but also strengthens the strength of the upper section 101 of the D-pillar inner panel. The reinforcement cavity 11 can be set as a closed cavity or a semi-closed cavity.

[0049] The rear door stay reinforcement plate 10 is formed by welding multiple plate-like structures together. The self-welding type rear door stay reinforcement plate 10 has stronger structural strength, ensuring the installation strength of the rear door stay and the stability of the opening and closing of the rear door.

[0050] In some embodiments, the rear door stay reinforcement plate 10 is connected to different positions of the upper section 101 of the D-pillar inner panel through multiple fourth flanges 12. Exemplarily, the multiple fourth flanges 12 are connected to multiple positions of the upper section 101 of the D-pillar inner panel by spot welding. One of the fourth flanges 12 of the rear door stay reinforcement plate 10 can be connected to the second retractor mounting plate 9 through a mounting bolt 13. During a collision, the second seat belt 300 is subjected to the pulling force of the passenger. This pulling force is instantaneously transmitted to the second retractor 500, and a large pulling force is applied at the mounting bolt 13 of the second retractor 500. This pulling force is dispersed to multiple surfaces of the upper section 101 of the D-pillar inner panel through the fourth flange 12 of the rear door stay reinforcement plate 10 and then transmitted to the vehicle body. This method improves the anti-deformation ability near the second retractor 500 of the upper section 101 of the D-pillar inner panel. Exemplarily, the mounting bolt 13 is directly welded to the fourth flange 12 of the rear door stay reinforcement plate 10, which is more convenient to operate, has higher welding efficiency, and avoids deformation of the workpiece during the welding process.

[0051] Furthermore, the upper mounting plate 7 of the second seat belt moves towards the front side of the vehicle body, changing the force application angle at the installation position of the second retractor 500 and optimizing the force transmission path.

[0052] In some embodiments, the upper section 103 of the D-pillar reinforcement plate is arranged at a position on the outer side of the upper section 101 of the D-pillar inner panel near the second retractor 500. The upper section 103 of the D-pillar reinforcement plate and the upper section 101 of the D-pillar inner panel are connected to form a cavity structure 14, improving the strength of the vehicle D-pillar 100 and its anti-deformation ability when the vehicle is collided. The D-pillar reinforcement plate is arranged at a position near the second retractor 500, which is beneficial to enhancing the structural strength near the second retractor 500.

[0053] The rear door hinge is installed on the rear cross member 600 of the roof panel.
