[0041] In response to the problem of poor strength of seat mounting structures in the related art, an embodiment of the present application provides a seat mounting structure and a vehicle.

[0042] Combine the following Figures 1 to 11 , describing an embodiment of the present application.

[0043] In a first aspect, an embodiment of the present application provides a seat mounting structure, comprising: a seat mounting hole 1 , a bushing structure 2 and a seat mounting bracket 3 .

[0044] Specifically, the seat mounting hole 1 is provided on the rear floor assembly 4; the bushing is passed through the seat mounting hole 1; and the seat mounting bracket 3 is passed through the bushing structure 2 and connected to the seat mounting hole 1 via a fastener.

[0045] The embodiment of the present application can disperse the force on the seat mounting hole 1 by arranging the bushing structure 2 in the seat mounting hole 1, reduce the risk of deformation of the seat mounting hole 1 due to excessive force, and improve the structural stability of the seat mounting structure. Furthermore, the bushing structure 2 can help the seat mounting bracket 3 maintain a relatively stable position, ensure that the seat does not move significantly under vehicle collision conditions, and protect passengers from secondary injuries caused by seat displacement. In addition, the bushing has a simple structure and small size. Its arrangement does not occupy the space of the rear floor and does not affect the arrangement of other parts on the upper surface of the rear floor assembly 4, thereby improving space utilization. In addition, the seat mounting bracket 3 is connected to the seat mounting hole 1 through fasteners, which can form a force transmission path from the seat mounting hole 1-seat mounting bracket 3-seat, disperse the force on the fasteners, and improve the rigidity of the seat mounting structure.

[0046] It is understandable that the number of seat mounting holes 1 in the embodiment of the present application can be, but is not limited to, three, four, and six, and can be adaptively adjusted according to actual design needs, and the present application does not make specific limitations here. In addition, the present application does not limit the setting position of the seat mounting holes 1 on the rear floor assembly 4, and can be adaptively set according to the position of the seat. For example, in a specific embodiment, a plurality of seat mounting holes 1 are arranged on the rear floor assembly 4 at intervals along the width direction of the vehicle, and a bushing structure 2 is provided in each seat mounting hole 1.

[0047] It should be noted that, in the embodiment of the present application, the rear floor assembly 4 includes a first connecting plate 401, a transition plate 402, and a second connecting plate 403 that are bent in sequence into a Z-shape. Specifically, the seat mounting hole 1 is provided on the second connecting plate 403, one end of the seat mounting bracket 3 is connected to the seat mounting hole 1 by a fastener, and the other end is fixed to the first connecting plate 401. In this way, the force borne by the seat mounting hole 1 can be transmitted to the rear floor assembly 4 and the entire vehicle body frame through the seat mounting bracket 3, thereby improving the safety and riding comfort of the vehicle.

[0048] In addition, in some embodiments of the present application, the first connecting plate 401, the transition plate 402, and the second connecting plate 403 are designed to be integrally formed, which can improve the integrity and strength of the rear floor assembly 4 and provide effective structural support for the seat mounting hole 1. In addition, in the embodiments of the present application, the material of the rear floor assembly 4 can be aluminum alloy or magnesium alloy. In this way, the rigidity of the seat mounting hole 1 can be improved while meeting the lightweight requirements of the vehicle.

[0049] It should be noted that the bushing structure 2 in the embodiment of the present application can be made of steel, so as to ensure that the bushing structure 2 can withstand the seat load and various dynamic forces during the operation of the vehicle for a long time, thereby improving the durability and reliability of the seat mounting structure.

[0050] In some embodiments of the present application, the bushing structure 2 is interference-fitted with the seat mounting hole 1. The bushing structure 2 is interference-fitted with the seat mounting hole 1 so that the bushing structure 2 fits closely with the seat mounting hole 1, thereby reducing the slight movement of the seat during the driving of the vehicle, which can improve the comfort of passengers in the vehicle and reduce the risk of secondary injury to passengers due to seat displacement.

[0051] In some embodiments of the present application, the bushing structure 2 is provided with an axial through hole 201, the fastener is a threaded fastener, the inner wall of the axial through hole 201 is provided with an internal thread that matches the thread of the threaded fastener, and the threaded fastener is threadedly connected to the axial through hole 201. By adopting a sleeve structure with an internal thread and a threaded fastener, it is possible to ensure that the seat mounting bracket 3 is stably connected to the seat mounting hole 1. In addition, compared with other connection methods such as welding or clamping, the threaded connection method is simpler and faster, which can improve the convenience of subsequent maintenance.

[0052] In some embodiments of the present application, the bushing structure 2 includes a bushing body 202 and an annular flange 203 provided at one end of the bushing body 202, the bushing body 202 is inserted into the seat mounting hole 1, the inner surface of the annular flange 203 overlaps the outer surface of the rear floor assembly 4, and the seat mounting bracket 3 is provided on the outer surface of the annular flange 203 and fastened by fasteners. It can be understood that by providing the annular flange 203 at one end of the bushing body 202, on the one hand, a preliminary limitation of the position of the bushing structure 2 can be formed, and on the other hand, a certain sealing effect can be played to prevent foreign substances such as moisture and dust from entering the interior of the vehicle through the seat mounting hole 1, thereby protecting the vehicle structure from corrosion and extending the service life of the vehicle. In addition, by providing the seat mounting bracket 3 on the outer surface of the annular flange 203, the damage caused by the seat mounting bracket 3 to the rear floor assembly 4 or the seat mounting hole 1 during the installation process can be reduced.

[0053] In a second aspect, an embodiment of the present application provides a vehicle, comprising: a rear floor assembly 4 and the above-mentioned seat mounting structure. Specifically, in the above-mentioned seat mounting structure, a seat mounting hole 1 is provided on the rear floor assembly 4, and a seat mounting bracket 3 is provided in a bushing structure 2 through a fastener and connected to the seat mounting hole 1.

[0054] The present application can improve the strength of the seat mounting hole 1 by setting the above-mentioned seat mounting structure on the rear floor assembly 4 of the vehicle, ensuring that the relative position of the rear seat and the rear floor will not change significantly under collision conditions, thereby providing good driving safety protection for the occupants on the seat. In addition, since the above-mentioned seat mounting structure improves the structural strength of the seat mounting hole 1, it can prevent the seat from moving or shaking unnecessarily during the driving of the vehicle, thereby improving the riding comfort of the passengers.

[0055] It should be noted that the vehicle in this application may refer to a large car, a small car, a special-purpose car, etc. For example, according to the car model, the car in this application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV) or other models. Generally, a vehicle is provided with wheels, a power source, and a transmission system arranged between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, so that the wheels rotate, thereby driving the vehicle to travel.

[0056] It should be noted that in the embodiments of the present application, the type of the power source of the vehicle is not limited. For example, for a fuel vehicle, the power source may refer to a fuel engine such as a gasoline engine or a diesel engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; for a vehicle powered by other means, the power source may refer to a device that generates power.

[0057] In some embodiments of the present application, the vehicle further includes: a floor panel 5 and a first connecting beam 6, the floor panel 5 is arranged on the rear floor assembly 4, the first connecting beam 6 is arranged on the floor panel 5, one end of the first connecting beam 6 is located between the rear floor assembly 4 and the seat mounting bracket 3, and is fastened by a fastener. By arranging one end of the first connecting beam 6 between the rear floor assembly 4 and the seat mounting bracket 3, on the one hand, the structural strength of the seat mounting structure can be improved, that is, the connection strength between the seat and the rear floor assembly 4 can be increased; on the other hand, a force transmission path from the seat mounting hole 1 to the first connecting beam 6 can be formed, so that the first connecting beam 6 can quickly disperse the force acting on the seat mounting hole 1, and improve the stability of the seat mounting structure under complex road conditions.

[0058] It should be noted that the end of the first connecting beam 6 in the embodiment of the present application close to the seat mounting hole 1 is located between the outer surface of the annular flange 203 and the seat mounting bracket 3. In addition, the embodiment of the present application does not limit the number of the first connecting beams 6, as long as the number of the first connecting beams 6 corresponds to the number of the seat mounting holes 1.

[0059] It should be noted that the floor panel 5 in the implementation of the present application can be mounted on the seat mounting hole 1, or can be set on one side of the seat mounting hole 1. It is understandable that no matter which installation method is used, a force transmission path from the seat mounting hole 1 to the floor panel 5 can be added to avoid stress concentration at the seat mounting hole 1, thereby improving the durability and safety of the seat mounting structure.

[0060] In addition, in order to further improve the strength of the seat mounting structure, in an embodiment not shown, the annular flange 203, the first connecting beam 6 and the seat mounting bracket 3 are connected by welding.

[0061] In some embodiments of the present application, a cavity 7 is formed between the first connecting beam 6 and the floor panel 5. By providing the cavity 7 between the first connecting beam 6 and the floor panel 5, the weight of the structure itself can be reduced without reducing the structural strength. In addition, by providing the cavity 7, crushing energy absorption under collision conditions can also be achieved, so that not only the safety performance of the seat installation structure can be improved, but also the safety performance of the vehicle can be improved.

[0062] In some embodiments of the present application, the first connecting beam 6 includes a top plate 601 and side plates disposed on opposite sides of the top plate 601, and a cavity 7 is formed between the top plate 601, the side plates and the floor panel 5. The combination of the top plate 601 and the side plates forms a "J"-shaped cross-sectional structure, which can improve the bending and torsional strength of the first connecting beam 6 itself, and has a positive effect on improving the rigidity of the seat mounting structure and the overall rigidity of the vehicle.

[0063] In some embodiments of the present application, weight-reducing and energy-absorbing holes 602 are provided on the top plate 601. By providing the weight-reducing and energy-absorbing holes 602 on the top plate 601, on the one hand, the weight of the first connecting beam 6 can be reduced to meet the design requirements of lightweight vehicles; on the other hand, crushing energy absorption under collision conditions can be achieved to improve the safety performance of the seat installation structure and the vehicle as a whole.

[0064] In some embodiments of the present application, the rear floor assembly 4 includes a rear floor body 404 and connecting arms 405 disposed on opposite sides of the rear floor body 404, and a U-shaped structure for mounting a floor panel 5 is formed between the rear floor body 404 and the connecting arms 405; the vehicle further includes a second connecting beam 8, which is connected to the floor panel 5 and the connecting arms 405 and is located at the opening of the U-shaped structure, and the first connecting beam 6 is connected to the second connecting beam 8 through the floor panel 5. By arranging the floor panel 5 between the U-shaped structure and the second connecting beam 8, a stable and firm mounting support can be provided for the first connecting beam 6, ensuring that the first connecting beam 6 can effectively play its own role. In addition, connecting the first connecting beam 6 with the second connecting beam 8 can further optimize the force transmission path, so that the force on the first connecting beam 6 can be transmitted to the entire vehicle body frame through the second connecting beam 8 and the rear floor assembly 4, thereby improving the safety performance of the seat mounting structure and the vehicle as a whole.

[0065] In addition, in order to improve the structural strength of the second connecting beam 8 itself, the cross section of the second connecting beam 8 along the vehicle width direction may be set to be Z-shaped.
