[0036] It should be understood that the term "and / or" used herein is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are in an "or" relationship.

[0037] In order to meet the market demand of all parties, automobile manufacturers platformize multiple vehicle models to improve the commonality among vehicle models. However, the traditional fuel commercial vehicle structure arranges the engine at the bottom of the front floor, and the front floor is provided with a central passage and a seat frame 30 structure. Due to the different seat arrangement heights of the fuel commercial vehicle and the new energy commercial vehicle, the heights of the retractor mounting positions on the left and right sides of the driver's cabin are different, causing the new energy vehicle model and the fuel vehicle model to need to develop different B-pillar upper / lower inner panels, resulting in an increase in production cost.

[0038] In order to solve the problem that the new energy vehicle model and the fuel vehicle model need to develop different B-pillar upper / lower inner panels, resulting in an increase in production cost, the present application provides a vehicle frame structure 100, Figure 1 A structural schematic diagram of a vehicle frame structure provided for the present embodiment, Figure 2 A retractor mounting position schematic diagram of a vehicle frame structure provided for the present embodiment, as Figure 1 And Figure 2As shown, including the frame floor 10 and the B-pillar inner panel 20 connected with the frame floor 10; the B-pillar inner panel 20 includes the B-pillar upper inner panel 21 and the B-pillar lower inner panel 22 connected with each other, and the joint of the B-pillar upper inner panel 21 and the B-pillar lower inner panel 22 forms a joint seam 23; the B-pillar lower inner panel 22 is provided with a seat belt retractor mounting position 25 at one end close to the B-pillar upper inner panel 21;

[0039] In the technical scheme of the present application, the reserved space of the seat belt retractor mounting position 25 is arranged in the interval of the B-pillar lower inner panel 22 close to the joint seam 23, so that the frame structure 100 can be adjusted for the seat belt retractor mounting position 25 when it is applied to different vehicle models, and the benefits of adjusting the seat belt retractor mounting position 25 to adapt to fuel vehicle models or new energy vehicle models are obvious. Therefore, by adjusting the position of the joint seam 23 between the B-pillar upper inner panel 21 and the B-pillar lower inner panel 22, the adjustment space of the seat belt retractor mounting position 25 is reserved to achieve the goal of sharing the frame structure 100 of fuel and new energy vehicle models.

[0040] In order to make the technical scheme, object and advantage of the present application more clear and obvious, the present application will be described in detail below in combination with the drawings and examples. At the same time, in order to facilitate understanding, the frame structure 100 is taken as the reference object of direction, the frame structure 100 is arranged on the ground along the horizontal direction, the direction perpendicular to the horizontal direction of the frame structure 100 and away from the ground is defined as upward, and vice versa; the direction of vehicle forward is defined as forward, and vice versa.

[0041] In some embodiments, please continue to refer to Figure 1 In the frame structure 100 in the technical scheme of the present application, the frame floor 10 is a square structure and is located at the bottom of the frame structure 100, and the frame floor 10 is the left and right side wall assemblies (not shown in the figure) of the frame structure 100, and the upper part of the frame structure 100 is provided with a roof assembly (not shown in the figure), that is, the frame floor 10, the left and right side wall assemblies (not shown in the figure) and the roof assembly (not shown in the figure) assemble the basic frame of the frame assembly. Among them, the B-pillar inner panel 20 belongs to part of the left and right side wall assemblies (not shown in the figure) and is arranged at the middle part of the side edge of the frame floor 10, and the B-pillar inner panel 20 in the present application is divided into two parts connected with each other, that is, the B-pillar upper inner panel 21 and the B-pillar lower inner panel 22. Among them, the B-pillar upper inner panel 21 and the B-pillar lower inner panel 22 are overlapped and welded to form a joint seam 23.

[0042] The height of the seat belt retractor mounting position 25 of the frame structure 100 currently applicable to fuel vehicle models and new energy vehicle models is different. In order to make the frame structure 100 of the present application have universality, in some embodiments, as Figure 2As shown, the distance A between the upper edge of the seat belt retractor mounting position 25 and the joint seam 23 is 55-85 mm when the vehicle frame structure 100 is applied to a fuel vehicle; the distance B between the upper edge of the seat belt retractor mounting position 25 and the joint seam 23 is 135-165 mm when the vehicle frame structure 100 is applied to a new energy vehicle.

[0043] Figure 3 A partial structural view of a vehicle frame structure is provided for the present embodiment, as shown in Figure 3 The seat belt retractor mounting position 25 is arranged on the surface of the B-pillar lower inner panel 22 facing the vehicle interior, and is provided with a square mounting groove 251 for passing through the seat belt retractor. Four mounting holes 252 are arranged at the four corners of the square mounting groove 251 for mounting bolts to fix the seat belt retractor. When the vehicle frame structure 100 is applied to different vehicle models, according to the distance between the upper edge of the seat belt retractor mounting position 25 and the joint seam 23, a special punching die and punching equipment can be used to punch out a seat belt retractor mounting position 25 with a corresponding height to meet the requirements of the corresponding vehicle model.

[0044] In some embodiments, the distance between the upper edge of the seat belt retractor mounting position 25 on the B-pillar inner panel 20 and the joint seam 23 is less than the distance between the upper edge of the reserved position 26 and the joint seam 23. In the present application, the seat frame 30 of the fuel vehicle is arranged on the floor of the vehicle frame, and the arrangement of the seat frame 30 interferes with the seat belt retractor (not shown in the figure). The seat belt retractor mounting position 25 can be adjusted from the initial position to the reserved position 26 to meet the needs of different vehicle models.

[0045] When the vehicle frame structure 100 is applied to a fuel vehicle, the distance A between the upper edge of the seat belt retractor mounting position 25 and the joint seam 23 is 55-85 mm, which can be 55 mm, 60 mm, 65 mm, 70 mm, 75 mm, 80 mm, 85 mm or any value between them.

[0046] When the vehicle frame structure 100 is applied to a new energy vehicle, the distance B between the upper edge of the seat belt retractor mounting position 25 and the joint seam 23 is 135-165 mm, which can be 135 mm, 140 mm, 145 mm, 150 mm, 155 mm, 160 mm, 165 mm or any value between them. At this time, the seat belt retractor mounting position 25 is in the initial position. The B-pillar inner panel 20 can be made of cold rolled steel or other materials; the processing method can be stamping, machining or other methods; the connection method can be spot welding, laser welding or other welding methods, which are not limited here.

[0047] In the above scheme, the safety belt retractor mounting position 25 is reserved in the B-pillar lower inner plate 22 to meet the different needs of fuel vehicle models and new energy vehicle models, and to meet the installation needs of safety belt retractors of different vehicle models, so as to achieve the universality of the B-pillar inner plate 20, and the production mold of the B-pillar inner plate 20 is shared, and the B-pillar inner plate 20 is applied to different vehicle models only by switching the punching mold, thereby saving the development investment cost.

[0048] In the technical scheme of the present application, the difference between the frame structure 100 of the fuel vehicle model and the new energy vehicle model is that the installation height of the safety belt retractor mounting position 25 is different, and the reason for the difference between the two frame structures 100 is that the seat frame 30 connected to the upper surface of the frame bottom plate 10 is arranged on the frame bottom plate 10 of the fuel vehicle model, and the lower edge of the safety belt retractor mounting position 25 is higher than the upper surface of the seat frame 30. If the seat frame 30 is installed on the existing frame structure 100, it will cause the safety belt retractor mounting position 25 to be blocked, so in the present application, the reserved position 26 is arranged between the upper edge of the safety belt retractor mounting position 25 and the splicing joint 23, and the reserved position 26 is used to adjust the installation height of the safety belt retractor mounting position 25.

[0049] Specifically, please continue to refer to Figure 1 , the seat frame 30 is a frame structure, and the seat frame 30 is arranged on the frame bottom plate 10 and is welded to the frame bottom plate 10.

[0050] The seat frame 30 can be made of cold-rolled sheet or other sheet materials; the processing method can be punching, mechanical processing or other methods; and the connection method can be spot welding, laser welding or other welding methods, which are not limited herein.

[0051] In the above scheme, the seat frame 30 has a simple structure and convenient operation, and the seat frame 30 can be easily attached to the existing frame structure 100 to meet the special needs of the frame structure 100 applied to fuel vehicle models.

[0052] The frame structure 100 of the present application can be shared by fuel vehicle models and new energy vehicle models, and the key point is to reserve space for different needs of two different vehicle models in structure and to seek common ground while reserving differences. Among them, because the fuel vehicle model needs to install the seat frame 30 on the frame structure 100, and the installed seat frame 30 will block the original safety belt retractor mounting position 25, that is, the safety belt retractor mounting position 25 of the fuel vehicle model is higher than that of the new energy vehicle model, so it is necessary to reserve different safety belt retractor mounting positions 25 on the basis of the original B-pillar structure, so it can be seen that the B-pillar structure plays a role in realizing the shared frame structure 100 of different vehicle models in the present application.

[0053] Figure 4A structure diagram of a B-pillar inner plate reinforcing plate of a vehicle frame structure is provided for the embodiment, please refer to Figure 3 and Figure 4 In order to improve the structural strength of the B-pillar inner plate 20, the B-pillar inner plate 20 further comprises a connected B-pillar inner plate reinforcing plate 27, which is a folded corner structure welded between the B-pillar lower inner plate 22 and the vehicle frame bottom plate 10.

The B-pillar inner plate reinforcing plate 27 is provided with a plurality of welding process holes 271, which can be welded into one body by spot welding, so that the strength of the existing B-pillar lower inner plate 22 is improved, and the opening direction of the shallow groove of the B-pillar lower inner plate 22 is towards the outside of the vehicle, so as to facilitate the B-pillar inner plate 20 to be attached to the vehicle side wall assembly (not shown in the figure) and form a cavity structure.

[0056] In the above scheme, the B-pillar inner plate reinforcing plate 27 can strengthen the connection between the B-pillar lower inner plate 22 and the vehicle frame bottom plate 10, improve the structural strength and rigidity of the local area of the vehicle body, meet the performance requirements of rigidity, strength, NVH (noise, vibration and sound roughness), and has simple structure, low process cost and practicality.
