Description

Technical Field

[0001] This application relates to the technical field of vehicle manufacturing, and particularly to a seat mounting structure and a vehicle. Background Art

[0002] Currently, the front seat mounting structure on the vehicle floor is a frame assembly structure formed by welding sheet metal vertical plates around an opening area after drilling a hole in the floor. The opening area is covered by a removably installed cover plate, which separates the interior and exterior spaces and environments of the vehicle. The seat is installed on the cover plate. In another existing solution, no hole is drilled in the floor, and the area under the seat uses a frame assembly structure formed by welding sheet metal vertical plates. The seat is directly installed on the frame structure formed by welding the sheet metal vertical plates. There is no hole in the floor, and the inside and outside of the vehicle body are not connected.

[0003] In the existing solutions, drilling a hole in the floor will affect the sealing performance of the vehicle cabin. However, in the solution without drilling a hole in the floor, although the sealing performance is not affected, the total weight of the frame assembly structure formed by welding sheet metal vertical plates is extremely large, which will seriously affect the vehicle's endurance.

[0004] In view of this, the present utility model is specifically proposed. Summary of the Utility Model

[0005] This application provides a seat mounting structure and a vehicle to solve the technical problems that the existing seat mounting structure is likely to affect the sealing performance of the vehicle cabin and the vehicle's endurance.

[0006] In the first aspect of the present utility model, a seat mounting structure is provided, which includes a mounting frame, a pair of U-shaped beams, and mounting brackets. The pair of U-shaped beams are respectively arranged at both ends of the mounting frame in the first direction. Each U-shaped beam has a closed end and an open end. The open end is connected to the mounting frame, and the closed end is used to support the mounting frame. The closed end of each U-shaped beam is connected to one end of at least one mounting bracket. The other end of each mounting bracket is located on one side of the corresponding closed end in the first direction and supports the mounting frame together with the closed end.

[0007] In this solution, through the combined design of the U-shaped beams and the mounting brackets, it is lighter than the traditional frame assembly structure formed by welding sheet metal vertical plates, and can effectively reduce the total weight of the seat mounting structure. The lightweight design not only reduces the energy consumption of the vehicle and increases the vehicle's endurance mileage, but also the cooperation between the mounting brackets and the closed ends of the U-shaped beams can ensure the stability and reliability of the seat mounting structure.

[0008] Through the reasonable layout and connection of the U-shaped beam and the mounting bracket, the seat mounting structure of the present utility model has good structural strength while maintaining light weight. This design can ensure the stability and safety of the seat under various road conditions and driving conditions. At the same time, the present utility model does not require opening holes in the floor, effectively improving the sealing performance of the cabin, reducing the intrusion of noise and dust, and enhancing the riding comfort of passengers.

[0009] In a further aspect of the present utility model, the mounting frame includes a pair of cross beams arranged in parallel along the first direction and a pair of longitudinal beams arranged in parallel along the second direction. Each end of each cross beam is respectively connected to a pair of longitudinal beams, and the non-closed end of each U-shaped beam is connected to a pair of longitudinal beams; the seat mounting structure further includes a support beam, and the support beam is obliquely connected to the U-shaped beam and the cross beam, and / or the support beam is obliquely connected to the U-shaped beam and the longitudinal beam.

[0010] In this aspect, by adding cross beams and longitudinal beams and connecting them in parallel to each other, a stable rectangular frame is formed, greatly improving the overall stability of the seat mounting structure. This structure can resist forces and vibrations from different directions, ensuring the smoothness and safety of the seat during driving. The addition of cross beams and longitudinal beams, as well as the connection between them, enables the seat mounting structure to bear a greater weight. This means that heavier and stronger seats can be installed, thus meeting the needs of passengers for comfort and safety. The support beam is obliquely connected to the U-shaped beam and the cross beam or the longitudinal beam, which can effectively disperse the forces generated by the seat and passengers, avoiding local stress concentration. This design not only improves the durability of the structure but also reduces the risk of deformation and damage caused by long-term stress.

[0011] In a further aspect of the present utility model, each U-shaped beam includes: a mounting portion on which the mounting bracket is provided; a bending portion located at both ends of the mounting portion in the second direction and together forming a closed end; and a pair of support portions, one end of each support portion is connected to a corresponding bending portion, and the other ends of the pair of support portions form a non-closed end.

[0012] In this aspect, by subdividing the U-shaped beam into a mounting portion, a bending portion, and a support portion, the structural stability and strength are ensured. The bending portion is located at both ends of the mounting portion and together forms a closed end, which enables the closed end to bear more supporting force, thereby enhancing the overall supporting effect of the seat mounting structure. The design of the mounting portion enables the mounting bracket to be stably arranged on the U-shaped beam, facilitating installation and disassembly. At the same time, the position of the mounting portion can be adjusted according to the specific requirements of the seat to adapt to different installation scenarios, enhancing the flexibility of the seat mounting structure. The design of the support portion makes the U-shaped beam more stable in structure. One end of each support portion is connected to a corresponding bending portion, and the other end forms a non-closed end. This structural layout enables the U-shaped beam to better disperse stress when subjected to external forces, reducing the risk of structural deformation and damage.

[0013] In a further aspect of the present utility model, the cross-sectional area of the U-shaped beam is larger than that of the cross beam and the longitudinal beam.

[0014] In this aspect, since the cross-sectional area of the U-shaped beam is larger than that of the cross beam and the longitudinal beam, it means that the U-shaped beam has a higher load-bearing capacity. In the seat mounting structure, the U-shaped beam often bears the main support and load-bearing tasks. Therefore, increasing its cross-sectional area can significantly improve the stability and safety of the entire seat mounting structure. The larger cross-sectional area enables the U-shaped beam to better disperse stress when bearing pressure, avoiding local damage caused by stress concentration. This can not only extend the service life of the U-shaped beam but also improve the overall durability of the seat mounting structure.

[0015] In a further aspect of the present utility model, the mounting bracket includes a main body portion and a reinforcing portion. The main body portion is disposed on the mounting portion, and the reinforcing portion is disposed around the main body portion.

[0016] In this aspect, the reinforcing portion is disposed around the main body portion, which can effectively increase the overall strength of the mounting bracket. This design makes the mounting bracket more stable and reliable when bearing the weight of the seat and the passenger, avoiding potential safety hazards caused by bracket deformation or damage. The setting of the reinforcing portion can also enhance the connection firmness between the mounting bracket and the U-shaped beam. By disposing the reinforcing portion around the main body portion, it can ensure that the connection between the mounting bracket and the U-shaped beam is tighter and not easily loosened or detached.

[0017] In a further aspect of the present utility model, the cross-section of the reinforcing portion is arc-shaped, with one end connected to the main body portion and the other end abutting against the U-shaped beam.

[0018] In this aspect, the design of the arc-shaped reinforcing portion can more effectively disperse and bear various external pressures and impacts. Compared with traditional linear reinforcing members, the arc-shaped structure can provide a more uniform stress distribution, thereby enhancing the stability and durability of the overall structure. Since one end of the arc-shaped reinforcing portion is directly connected to the main body portion and the other end abuts against the U-shaped beam, this design can ensure smooth stress transfer between the main body portion, the reinforcing portion, and the U-shaped beam. This helps to reduce stress concentration and lower the risk of structural damage.

[0019] In a further aspect of the present utility model, the main body portion includes: a first connecting portion, disposed on the mounting portion and used for mounting on the vehicle body; a second connecting portion, spaced from the first connecting portion in the third direction and used for mounting on the vehicle body; and an extending portion, obliquely connecting the first connecting portion and the second connecting portion.

[0020] In this solution, the first connecting part and the second connecting part are spaced apart in the third direction and are both used for installation on the vehicle body. This design provides a way of double-point or multi-point fixation, significantly enhancing the connection stability between the main body part and the vehicle body. Whether in the horizontal direction or the vertical direction, the body part can be more firmly fixed on the vehicle body, reducing loosening or displacement caused by vibration or impact. Optimize stress distribution: The design of the extending part with an oblique connection not only connects the first connecting part and the second connecting part, but also can effectively disperse and transfer the stress from the vehicle body. This makes the stress distribution more uniform, avoids the problem of single-point stress concentration, and improves the durability of the entire body structure. The first connecting part, the second connecting part and the extending part together constitute the main frame of the body part. When subjected to external forces, this structure can effectively resist deformation and fracture, ensuring the integrity and functionality of the body part.

[0021] In a further solution of the present utility model, a first connection hole is provided on the first connecting part for connecting the installation part; a second connection hole is provided on the second connecting part for installation on the vehicle body.

[0022] In a further solution of the present utility model, each U-shaped beam connects two installation brackets arranged at intervals. The axial center connection lines of the first connection holes of the two installation brackets are parallel to each other, and the axial center connection lines of the second connection holes of the two installation brackets are parallel to each other.

[0023] The second aspect of the present utility model provides a vehicle, including a seat, a vehicle body, and the seat installation structure provided by the first aspect of the present utility model. The seat is installed on the installation frame of the seat installation structure, one end of the installation bracket and the U-shaped beam are fixedly installed on the vehicle body, and one end of the installation bracket is fixedly installed on the vehicle body.

[0024] In summary, the seat installation structure and the vehicle provided by this application have at least the following beneficial effects:

[0025] Through the combined design of the U-shaped beam and the installation bracket, it is lighter than the traditional frame assembly structure welded by sheet metal vertical plates, and can effectively reduce the total weight of the seat installation structure. The lightweight design not only reduces the energy consumption of the vehicle and increases the vehicle's cruising range, but also the cooperation between the installation bracket and the closed end of the U-shaped beam can ensure the stability and reliability of the seat installation structure.

[0026] Through the reasonable layout and connection of the U-shaped beam and the installation bracket, the seat installation structure of the present utility model has good structural strength while maintaining lightweight. This design can ensure the stability and safety of the seat under various road conditions and driving conditions. At the same time, the present utility model does not require opening holes on the floor, effectively improving the airtightness of the cabin, reducing the intrusion of noise and dust, and enhancing the passenger's riding comfort.

[0040] Please refer to Figure 1 , a first aspect of the present utility model provides a seat mounting structure, including a mounting frame 100, a pair of U-shaped beams 200, and mounting brackets 300; the pair of U-shaped beams 200 are respectively arranged at both ends of the mounting frame 100 in the first direction X1, each U-shaped beam 200 has a closed end and an open end, the open end is connected to the mounting frame 100, and the closed end is used to support the mounting frame 100; the closed end of each U-shaped beam 200 is connected to one end of at least one mounting bracket 300, and the other end of each mounting bracket 300 is located on one side of the corresponding closed end in the first direction X1 and supports the mounting frame 100 together with the closed end.

[0041] In this solution, through the combined design of the U-shaped beam 200 and the mounting bracket 300, it is lighter than the box-type assembly structure welded by traditional welded sheet metal vertical plates, and can effectively reduce the total weight of the seat mounting structure. The lightweight design not only reduces the energy consumption of the vehicle and increases the vehicle's cruising range, but also the cooperation between the mounting bracket 300 and the closed end of the U-shaped beam 200 can ensure the stability and reliability of the seat mounting structure.

[0042] Through the reasonable layout and connection of the U-shaped beam 200 and the mounting bracket 300, the seat mounting structure of the present utility model not only maintains lightweight but also has good structural strength while. This design can ensure the stability and safety of the seat under various road conditions and driving conditions. At the same time, the present utility model does not require opening holes in the floor, effectively improving the sealing performance of the cabin, reducing the intrusion of noise and dust, and enhancing the riding comfort of passengers.

[0043] In a further embodiment, the mounting frame 100 includes a pair of cross beams 120 arranged in parallel along the first direction X1 and a pair of longitudinal beams 110 arranged in parallel along the second direction X2. Both ends of each cross beam 120 are respectively connected to a pair of longitudinal beams 110, and the non-closed end of each U-shaped beam 200 is connected to a pair of longitudinal beams 110; the seat mounting structure further includes a support beam 400, and the support beam 400 is obliquely connected to the U-shaped beam 200 and the cross beam 120, and / or the support beam 400 is obliquely connected to the U-shaped beam 200 and the longitudinal beam 110.

[0044] In this solution, by adding cross beams 120 and longitudinal beams 110 and connecting them in parallel with each other, a stable rectangular frame is formed, greatly improving the overall stability of the seat mounting structure. This structure can resist forces and vibrations from different directions, ensuring the smoothness and safety of the seat during driving. The addition of the cross beams 120 and longitudinal beams 110 and their connection enable the seat mounting structure to bear a greater weight. This means that heavier and stronger seats can be installed, thus meeting the needs of passengers for comfort and safety. The support beam 400 is obliquely connected to the U-shaped beam 200 and the cross beam 120 or the longitudinal beam 110, which can effectively disperse the forces generated by the seat and passengers, avoiding local stress concentration. This design not only improves the durability of the structure but also reduces the risk of deformation and damage caused by long-term stress.

[0045] Please refer further to Figure 2 , in a further embodiment, each U-shaped beam 200 includes: a mounting portion 230, on which the mounting bracket 300 is provided; a bending portion 220, located at both ends of the mounting portion 230 in the second direction X2 and together constituting a closed end; and a pair of support portions 210, one end of each support portion 210 is connected to a corresponding bending portion 220, and the other ends of the pair of support portions 210 constitute a non-closed end.

[0046] In this solution, the U-shaped beam 200 is subdivided into a mounting portion 230, a curved portion 220 and a support portion 210, thereby ensuring structural stability and strength. The curved portions 220 are located at both ends of the mounting portion 230 and together constitute a closed end, which enables the closed end to bear more supporting force, thereby enhancing the overall supporting effect of the seat mounting structure. The design of the mounting portion 230 enables the mounting bracket 300 to be firmly set on the U-shaped beam 200, which is convenient for installation and disassembly. At the same time, the position of the mounting portion 230 can be adjusted according to the specific needs of the seat to adapt to different installation scenarios, thereby enhancing the flexibility of the seat mounting structure. The design of the support portion 210 makes the U-shaped beam 200 more structurally stable. One end of each support portion 210 is connected to a corresponding curved portion 220, and the other end constitutes a non-closed end. This structural layout enables the U-shaped beam 200 to better disperse stress when subjected to external forces, thereby reducing the risk of structural deformation and damage.

[0047] In further embodiments, the cross-sectional area of ​​the U-shaped beam 200 is greater than the cross-sectional areas of the cross beam 120 and the longitudinal beam 110 .

[0048] In this solution, since the cross-sectional area of ​​the U-shaped beam 200 is larger than that of the cross beam 120 and the longitudinal beam 110, this means that the U-shaped beam 200 has a higher load-bearing capacity. In the seat mounting structure, the U-shaped beam 200 often bears the main support and load-bearing tasks, so increasing its cross-sectional area can significantly improve the stability and safety of the entire seat mounting structure. The larger cross-sectional area enables the U-shaped beam 200 to better disperse stress when subjected to pressure and avoid local damage caused by stress concentration. This can not only extend the service life of the U-shaped beam 200, but also improve the overall durability of the seat mounting structure.

[0049] In a further embodiment, the mounting bracket 300 includes a main body portion 310 and a reinforcing portion 320 . The main body portion 310 is disposed on the mounting portion 230 , and the reinforcing portion 320 is disposed around the main body portion 310 .

[0050] In this solution, the reinforcement part 320 is arranged around the main body 310, which can effectively increase the overall strength of the mounting bracket 300. This design makes the mounting bracket 300 more stable and reliable when bearing the weight of the seat and the passenger, and avoids the safety hazard caused by the deformation or damage of the bracket. The provision of the reinforcement part 320 can also enhance the connection firmness between the mounting bracket 300 and the U-shaped beam 200. By providing the reinforcement part 320 around the main body 310, it can be ensured that the connection between the mounting bracket 300 and the U-shaped beam 200 is tighter and not easy to loosen or fall off.

[0051] In a further embodiment, the cross-section of the reinforcing portion 320 is arc-shaped, with one end connected to the main body portion 310 and the other end abutting against the U-shaped beam 200.

[0052] In this solution, the design of the arc-shaped reinforcing portion 320 can more effectively disperse and withstand various external pressures and impacts. Compared with traditional straight-shaped reinforcing members, the arc-shaped structure can provide a more uniform stress distribution, thereby enhancing the stability and durability of the overall structure. Since one end of the arc-shaped reinforcing portion 320 is directly connected to the main body portion 310 and the other end abuts against the U-shaped beam 200, this design can ensure the smooth transfer of stress among the main body portion 310, the reinforcing portion 320, and the U-shaped beam 200. This helps to reduce the stress concentration phenomenon and lower the risk of structural damage.

[0053] In a further embodiment, the main body portion 310 includes: a first connection portion 323, disposed on the mounting portion 230 and used for mounting on the vehicle body; a second connection portion 321, spaced from the first connection portion 323 in the third direction X3 and used for mounting on the vehicle body; and an extension portion 322, obliquely connecting the first connection portion 323 and the second connection portion 321.

[0054] In this solution, the first connection portion 323 and the second connection portion 321 are spaced from each other in the third direction X3 and are both used for mounting on the vehicle body. This design provides a double-point or multi-point fixing method, significantly enhancing the connection stability between the main body portion 310 and the vehicle body. Whether in the horizontal direction or the vertical direction, the main body can be more firmly fixed on the vehicle body, reducing loosening or displacement caused by vibration or impact. Optimize stress distribution: The obliquely connected extension portion 322 is designed not only to connect the first connection portion 323 and the second connection portion 321, but also to effectively disperse and transfer the stress from the vehicle body. This makes the stress distribution more uniform, avoiding the problem of single-point stress concentration and improving the durability of the entire main body structure. The first connection portion 323, the second connection portion 321, and the extension portion 322 together form the main frame of the main body. When subjected to external forces, this structure can effectively resist deformation and fracture, ensuring the integrity and functionality of the main body.

[0055] In a further embodiment, a first connection hole 323A is provided on the first connection portion 323 to connect the mounting portion 230; a second connection hole 321A is provided on the second connection portion 321 for mounting on the vehicle body.

[0056] In a further embodiment, each U-shaped beam 200 is connected to two mounting brackets 300 arranged at intervals. The axial center connection lines of the first connection holes 323A of the two mounting brackets 300 and the second connection holes 321A are parallel to each other. The axial center connection line of the first connection holes 323A of the two mounting brackets 300 and the axial center connection line of the second connection holes 321A of the two mounting brackets 300 are parallel to each other.
