[0030] The embodiments of the present application are described in detail below, and the embodiments described with reference to the drawings are exemplary, and the embodiments of the present application are described in detail below.

[0031] The seat mounting structure according to the embodiments of the present application is described below with reference to Figures 1-4 , and the present application also proposes a vehicle.

[0032] Referring to Figures 1-4 , the seat mounting structure of the present application embodiment comprises: a seat framework 10, a seat mounting longitudinal beam 20, a seat mounting plate 30 and at least two mounting sleeves 40.

[0033] The seat mounting longitudinal beam 20 is arranged below the seat framework 10. Specifically, compared with the existing mounting point, the mounting point may be designed into different structures due to the requirements of the mounting cross beam or other mounting arrangements, resulting in inconsistent structures around the mounting point and irregular structure design. The structure of the seat mounting plate 30 cannot be universal, and the design and development costs are relatively high. The seat mounting longitudinal beam 20 has a small transverse size, and other structures can be designed to avoid the seat mounting longitudinal beam 20, so that the cross-sectional size of the seat mounting longitudinal beam 20 is not too constrained, and the universality is high, which ensures the strength of the structure around the seat mounting point while reducing the design and development costs.

[0034] The seat mounting longitudinal beam 20 can provide a better space size, and when a larger seat is arranged, the number of seat mounting points can be increased to share the force on the seat. When the seat and the occupant are subjected to a larger impact load, the height of the center of gravity of the seat and the occupant relative to the floor 50 will be much higher, and the moment of force will be multiplied. The seat mounting point needs a stronger structure and mounting point to share the load. The seat longitudinal mounting beam and the seat rail mounting point are on the same horizontal line. In the case of meeting the seat arrangement, the number of lower seat mounting points can be increased to improve the seat mounting strength.

[0035] In addition, the seat mounting longitudinal beam 20 has a strong stiffness performance, which can meet the needs of arranging the mounting point with good stiffness, thereby reducing the cost of redeveloping parts.

[0036] The seat mounting plate 30 is arranged between the seat framework 10 and the seat mounting longitudinal beam 20 and connected with the seat mounting longitudinal beam 20. One end of at least two mounting sleeves 40 is fixed on the seat framework 10, and the fastener 61 is fixedly connected with the seat mounting plate 30 after penetrating the mounting sleeve 40.

[0037] Specifically, the seat mounting plate 30 is connected with the seat mounting longitudinal beam 20, and the fastener 61 is fixedly connected with the seat mounting plate 30 after penetrating the mounting sleeve 40. One end of the mounting sleeve 40 is fixed on the seat framework 10. The seat framework 10, the seat mounting plate 30 and the seat mounting longitudinal beam 20 can be fixed by the fastener 61 and the mounting sleeve 40, thereby improving the stability of the seat framework 10.

[0038] The mounting sleeve 40 is provided with at least two, as shown in the embodiment, two mounting sleeves 40 are arranged on the left and right of the seat mounting structure, which can share the impact load of the seat framework 10 and improve the stability of the seat framework 10. Figure 1

[0039] ​Further, the seat mounting longitudinal beams 20 are matched with the mounting sleeves 40, distributed left and right on the seat mounting structure, and the seat mounting longitudinal beams 20 are provided with three mounting points, each of which is fixed with the mounting sleeve 40, the seat mounting plate 30, the seat mounting longitudinal beam 20 and the seat framework 10 through the fastener 61, which can effectively strengthen the strength of the seat mounting points, effectively share the load of the whole seat, and improve the stability of the seat framework 10.

[0040] The vehicle generally bears the greatest impact in the driving direction, and when the vehicle is running at high speed, the driving direction is suddenly blocked, and due to inertia, the independent seat and the occupant will remain in the original state for a period of time, so that the seat and the seat mounting point will bear a large load, and the longitudinal deformation resistance of the seat mounting longitudinal beam 20 is stronger, and the number of mounting points is large, which can effectively share the longitudinal impact load to each mounting point, resist the forward deformation of the seat and the deformation of the mounting point.

[0041] In this embodiment, the fastener 61 is an M8 bolt.

[0042] Therefore, the seat framework 10 is fixed by the fastener 61 and the mounting sleeve 40, and three mounting points are arranged on the seat mounting longitudinal beam 20, which can effectively strengthen the strength of the seat mounting points, effectively share the load of the whole seat, and improve the stability of the seat framework 10.

[0043] Referring to Figures 1-4 As shown in FIG. 1, the seat mounting plate 30 includes two support plates and a connecting plate, the two support plates are arranged at both ends of the connecting plate, the two support plates are connected with the seat mounting longitudinal beam 20, the connecting plate is connected with the seat framework 10, and a cavity is formed between the two support plates and the connecting plate. In this way, the two support plates and the connecting plate can enhance the stability and load-bearing capacity of the seat mounting plate 30, effectively share the impact load of the seat mounting structure, and ensure the stability of the seat. The connection of the support plate and the seat mounting longitudinal beam 20 can provide additional support to the seat mounting longitudinal beam 20. The cavity structure can increase the vibration resistance and reduce the overall weight.

[0044] Referring to Figures 1-4As shown, the support plate is provided with at least one first mounting flange 31 on the side facing the seat mounting longitudinal beam 20, and the first mounting flange 31 is connected with the seat mounting longitudinal beam 20. By connecting the first mounting flange 31 with the seat mounting longitudinal beam 20, the contact area of the connection is increased, the connection is more firm and less likely to loosen, thereby improving the stability of the seat. Moreover, the design of the flange helps to more evenly distribute the load from the seat mounting longitudinal beam 20, reducing local pressure concentration, thereby improving the durability and load-bearing capacity of the seat mounting plate 30. During installation, the first mounting flange 31 can be directly docked with the seat mounting longitudinal beam 20, simplifying the installation steps, saving time and effort, preventing misalignment or loosening during installation, and improving the reliability of the installation.

[0045] Moreover, since the seat mainly bears the load from the longitudinal impact, the lap joint of the longitudinal structural member needs to be specially designed for reinforcement. The first mounting flange 31 is arranged at the joint position of the two ends of the seat mounting longitudinal beam 20, and can serve as a reinforcing structure of the seat mounting longitudinal beam 20. When the seat and the occupant bear increased longitudinal impact load, the occupant will have an acceleration difference relative to the seat due to inertia, and the occupant will have relative movement relative to the seat. Under the action of the safety belt, the relative movement of the occupant and the seat is reduced, and the impact load borne by the occupant is transmitted to the seat through the safety belt, and then to the seat mounting longitudinal beam 20. At this time, the seat mounting longitudinal beam 20 bears a large longitudinal load, and the first mounting flange 31 in the form of a self-welding member is designed at the joint position of the two ends of the seat mounting longitudinal beam 20 to strengthen the strength of the seat mounting longitudinal beam 20.

[0046] Referring to Figures 1-3 As shown, the seat mounting structure further includes a floor 50 arranged below the seat framework 10, and the floor 50 is clamped between the mounting sleeve 40 and the seat mounting plate 30, and the seat mounting plate 30 and the floor 50 are fixedly connected. In this way, the fastener 61 passes through the mounting sleeve 40 and is fixedly connected with the bottom plate, the seat mounting plate 30 and the seat mounting longitudinal beam 20, respectively, so as to firmly fix the seat framework 10 to the vehicle body and ensure the strength of the seat installation.

[0047] Referring to Figure 4 As shown, the seat mounting longitudinal beam 20 is provided with at least two second mounting flanges 21 on the side facing the floor 50, and the at least two second mounting flanges 21 are fixedly connected with the floor 50. The seat mounting longitudinal beam 20 can strengthen the connection strength with the floor 50 through the second mounting flanges 21, thereby ensuring the stability of the seat.

[0048] Moreover, the second mounting flange 21 is connected with part of the first mounting flange 31, and the seat mounting longitudinal beam 20 and the seat mounting plate 30 can be fixedly connected to the floor 50 together through the mounting nut.

[0049] Referring to Figure 1As shown, the floor 50 is provided with a stepped portion 51 on the side facing the seat mounting plate 30, and the seat mounting plate 30 and the stepped portion 51 are in abutment. By providing the stepped portion 51 structure at the lap joint position of the floor 50 and the seat mounting plate 30, the rigidity performance of the mounting surface is ensured. The seat mounting plate 30 and the seat mounting longitudinal beam 20 are respectively welded by two lap joint surfaces. When the mounting point of the seat is subjected to a large pulling force, the load is shared by the four lap joint surfaces of the seat mounting plate 30 and the seat mounting longitudinal beam 20, the stress concentration on the seat mounting plate 30 is reduced, and the part is prevented from being pulled and broken.

[0050] Referring to Figure 4 As shown, the seat mounting structure further includes a seat front cross beam 62 and a seat rear cross beam 63, the seat front cross beam 62 and the seat rear cross beam 63 are arranged at both ends of the seat framework 10, and the seat mounting longitudinal beam 20 is connected between the seat front cross beam 62 and the seat rear cross beam 63. Specifically, the seat mounting longitudinal beam 20 is arranged on the floor 50 and is lap jointed on the seat front cross beam 62 and the seat rear cross beam 63 by welding points. The size space provided by the seat front cross beam 62 and the seat rear cross beam 63 can strengthen the structure of the periphery of the seat mounting longitudinal beam 20, and can resist part of the deformation when the seat is subjected to impact load.

[0051] In the embodiment, the seat can be a six-segment seat, the lower end of which is arranged with eight seat mounting points, the seat is connected to the vehicle body by eight fasteners 61, the lower end is locally reinforced by eight seat mounting plates 30, and the seat mounting longitudinal beam 20 is mounted between the seat front cross beam 62 and the seat rear cross beam 63. Because the seat front cross beam 62 and the seat rear cross beam 63 have a larger cross-sectional size, the local rigidity of the periphery structure of the seat mounting longitudinal beam 20 can be strengthened.

[0052] In addition, parallel welding is performed between the mounting sleeve 40 and the seat framework 10. That is, the mounting sleeve 40 is connected to the seat framework 10 in the form of a weld joint, and the position where the contact surface of the mounting sleeve 40 is connected to the seat framework 10 adopts parallel welding, which is more conducive to bearing the pressure load of the seat and has relatively good fatigue strength.

[0053] Referring to Figures 2-4 As shown, the seat framework 10 includes a plurality of connecting beams 11, the plurality of connecting beams 11 are arranged at intervals in the transverse direction, and the connecting beams 11 are fixedly connected to the seat mounting plate 30. That is, the fastener 61 and the sleeve are fixedly connected to the seat framework 10 through the connecting beam 11, so as to fixedly connect the seat fastener to the floor 50, the seat mounting plate 30 and the seat mounting longitudinal beam 20.

[0054] The vehicle according to the second aspect of the utility model comprises a seat mounting structure.
