Description

Technical Field

[0001] This application relates to the field of automotive seat technology, and more specifically to an automotive seat mounting assembly. Background Technology

[0002] In the field of vehicle technology, vehicle seats are one of the internal components of the vehicle's cockpit, serving four main functions: support, positioning, comfort, and safety protection. For a seat to function effectively in a vehicle, in addition to its own structure and strength, the strength of its installation on the vehicle body and the strength of the seat mounting points are also crucial. If the seat's installation structure is insufficiently strong, it will fail to secure the seat in a traffic accident, causing significant injury to occupants and also affecting passenger comfort.

[0003] Currently, in existing technologies, vehicle seating arrangements typically involve placing the seat beams on the floor, with connections solely secured by welds. However, with the widespread adoption of integrated seat belts in commercial vehicles, sudden braking can strain the welds, potentially causing the seat beams to detach. Furthermore, the seat beams are currently fixed to the floor beams and sill plates using only spot welding with flanges. However, this flanged structure is relatively weak, significantly reducing the connection strength of the seat beams and resulting in insufficient seat stability. This not only poses safety hazards but also reduces passenger comfort and overall user experience. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, this application provides an automotive seat mounting assembly that not only improves structural strength and connection strength, but also enhances safety and user experience.

[0005] This invention provides an automotive seat mounting assembly, the automotive seat mounting assembly structure comprising:

[0006] An independent seat beam assembly is welded to the floor longitudinal beam and the floor sill beam. The floor is installed on the seat beam assembly and is connected to the seat beam assembly by spot welding. The seat beam assembly is U-shaped.

[0007] An independent seat bracket is mounted on the seat beam assembly. The seat bracket is a "U"-shaped bracket and is connected to the seat beam assembly by spot welding.

[0008] When the seat beam assembly and the seat bracket are welded to the floor, they form a double-layer closed cavity structure with the floor.

[0009] According to an embodiment of the present invention, the automotive seat mounting assembly includes a front seat beam assembly and a rear seat beam assembly, and the seat bracket includes a left seat bracket and a right seat bracket.

[0010] According to an embodiment of the present invention, the front seat beam assembly and the rear seat beam assembly are respectively disposed on two flange sides of the floor longitudinal beam and the upper side of the floor sill beam, and the front seat beam assembly and the rear seat beam assembly are fixedly connected to the floor longitudinal beam and the floor sill beam by welding.

[0011] According to an embodiment of the present invention, the front seat beam assembly is inserted into the floor, the floor longitudinal beam and the floor sill beam at their overlapping points, and is fixedly connected by spot welding of three layers of material; the rear seat beam assembly is inserted into the floor, the floor longitudinal beam and the floor sill beam at their overlapping points, and is fixedly connected by spot welding of three layers of material.

[0012] According to the embodiment of the present invention, the left seat bracket and the right seat bracket are both "U"-shaped brackets, and the "U"-shaped sides of the left seat bracket and the right seat bracket are respectively spot-welded to the front seat beam in the front seat beam assembly and the rear seat beam in the rear seat beam assembly.

[0013] According to the embodiment of the present invention, the car seat mounting assembly provided has seat mounting holes and nuts on the upper surface of the left seat bracket and the right seat bracket that are in contact with the floor, and the seat is fixed to the left seat bracket and the right seat bracket by bolts.

[0014] According to an embodiment of the present invention, in the automotive seat mounting assembly, the floor, the left seat bracket, and the right seat bracket are drawn together to form a convex structure, and the convex structure of the floor and the rear seat beam assembly form a cavity; the left seat bracket and the right seat bracket are disposed in the cavity.

[0015] According to the automotive seat mounting assembly provided in the embodiments of the present invention, the upper surface of the convex structure of the floor is a horizontal plane; the upper surfaces of the left seat bracket and the right seat bracket are horizontal planes and are in contact with the upper surface of the convex structure of the floor.

[0016] According to an embodiment of the present invention, in the automotive seat mounting assembly, the width of the convex structure of the floor is smaller than the width of the longitudinal beam of the floor.

[0017] According to an embodiment of the present invention, the left seat bracket is disposed in the clamping cavity and inserted into the overlapping part of the floor and the rear seat beam assembly, and is fixedly connected by spot welding of three layers of material; the right seat bracket is disposed in the clamping cavity and inserted into the overlapping part of the floor and the rear seat beam assembly, and is fixedly connected by spot welding of three layers of material.

[0018] The beneficial effects of this invention are as follows: The automotive seat mounting assembly provided in this embodiment places the seat beam assembly under the floor. During sudden braking, when the seatbelt is stretched, the floor primarily provides a reaction force to the front and rear seat beam assemblies, effectively counteracting the tension of the seatbelt and reducing the load on the weld points of the seat beam assembly, thus significantly reducing the risk of the seat beam assembly being pulled off. Furthermore, the seat beam assembly is inserted into the floor, floor longitudinal beams, and floor sill beams at their overlapping points and is spot-welded with three layers of material. Compared to flanged connections, this insertion connection significantly improves the connection strength of the seat beam assembly. Moreover, the seat bracket fits flush with the upper surface of the floor's raised structure and is horizontal, ensuring the seat remains horizontally installed even in structures like automobiles where the floor is raised. This not only facilitates seat installation but also prevents the seat from shearing the bolts under the force of gravity during use, thus avoiding bolt breakage. Attached Figure Description

[0030] Because existing commercial vehicle seat beams rely solely on welds to connect to the floor, sudden braking and the tightening of the seat belts can severely stress these welds, potentially leading to seat beam detachment. Furthermore, the seat beams are typically fixed to the floor longitudinal beams and sill inner panels using only spot welding with flanges. However, the flanged structure is relatively weak, significantly reducing the connection strength and resulting in insufficient seat fixation. Therefore, this embodiment provides an automotive seat mounting assembly that not only improves structural and connection strength but also enhances safety and user experience.

[0031] like Figure 1 , Figure 2 The diagram shown is a schematic of a car seat mounting assembly structure provided in this embodiment. The car seat mounting assembly structure includes: an independent seat beam assembly 3 and an independent seat bracket.

[0032] The seat beam assembly 3 is welded to the floor longitudinal beam 4 and the floor sill beam 6. The floor 2 is mounted on the seat beam assembly 3 and connected to the seat beam assembly 3 by spot welding. The seat beam assembly 3 is U-shaped. The seat bracket is mounted on the seat beam assembly 3 and is also U-shaped. The seat bracket is connected to the seat beam assembly 3 by spot welding. When the seat beam assembly 3 and the seat bracket are welded to the floor 2, they form a double-layer closed cavity structure with the floor 2.

[0033] Specifically, the automotive seat mounting assembly structure provided in this embodiment includes an independent seat beam assembly 3 and a seat bracket. The seat beam assembly 3 is welded and fixed to the vehicle floor 2 between the floor longitudinal beam 2 and the floor sill beam 6. Both the seat beam assembly 3 and the seat bracket have a "U"-shaped cross-section. This embodiment of the invention, by setting the seat beam assembly 3 and the seat bracket as separate independent mechanisms, can meet the requirements of diverse seat installations. For different types or functions of seats, only the seat mounting bracket needs to be changed to meet the seat assembly requirements. Since the seat beam assembly 3 and the seat bracket provided in this embodiment have "U"-shaped cross-sections, when the seat beam assembly 3 and the seat bracket are welded to the floor 2, they form a double-layer closed cavity structure with the vehicle floor 2, thereby effectively improving the strength of the seat beam assembly 3 and the seat bracket, and also enhancing side-impact safety performance. The automotive seat mounting assembly provided in this embodiment improves the structure of the seat beam assembly 3 and the seat bracket, while meeting the strength requirements for side collisions of the vehicle, reducing the cost of seat assembly manufacturing and assembly, and improving the adaptability to different seats.

[0034] like Figure 2, Figure 3 As shown, the seat beam assembly 3 provided in this embodiment includes a front seat beam assembly 7 and a rear seat beam assembly 5, as well as a floor longitudinal beam 4 and a floor sill beam 6 connected to the front seat beam assembly 7 and the rear seat beam assembly 5, forming an overall seat beam frame structure.

[0035] Specifically, the front seat beam assembly 7 rests flat against the two flange edges of the floor longitudinal beam 4 and the upper side of the floor sill beam 6, and is fixedly connected by spot welding. Similarly, the rear seat beam assembly 5 rests flat against the two flange edges of the floor longitudinal beam 4 and the upper side of the floor sill beam 6, and is fixedly connected by spot welding. The floor cover rests on the frames of the front seat beam assembly 7 and the rear seat beam assembly 5, and is fixedly connected to the frames of the front seat beam assembly 7 and the rear seat beam assembly 5 by spot welding. In this embodiment, both the front seat beam assembly 7 and the rear seat beam assembly 5 are located under the floor 2. When the vehicle brakes suddenly and the seat belt is pulled, the floor 2 provides a reaction force to the front seat beam assembly 7 and the rear seat beam assembly 5 to counteract the tension of the seat belt on the front seat beam assembly 7 and the rear seat beam assembly 5. This greatly reduces the stress load at the weld points of the front seat beam assembly 7 and the rear seat beam assembly 5, and reduces the risk of the front seat beam assembly 7 and the rear seat beam assembly 5 being pulled off.

[0036] like Figure 2 , Figure 3 As shown, when the floor covers the frames of the front seat beam assembly 7 and the rear seat beam assembly 5, the two long sides of the "U"-shaped front seat beam assembly 7 are respectively inserted into the overlapping points of the floor 2, the floor longitudinal beam 4, and the floor sill beam 6, and are fixedly connected to the floor 2, the floor longitudinal beam 4, and the floor sill beam 6 by three-layer spot welding. Similarly, in the rear seat beam assembly 5, the two long sides of the "U"-shaped rear seat beam assembly 5 are respectively inserted into the overlapping points of the floor 2, the floor longitudinal beam 4, and the floor sill beam 6, and are fixedly connected to the floor 2, the floor longitudinal beam 4, and the floor sill beam 6 by three-layer spot welding. In this embodiment, the front seat beam assembly 7 and the rear seat beam assembly 5 are fixedly connected by three-layer spot welding, and compared with most current connections that use flange welding, the connection between the front seat beam assembly 7 and the rear seat beam assembly 5 in this embodiment greatly improves the connection strength. In this embodiment, important connection parts are all sandwiched between two large components using load-bearing parts, and the three layers of material are welded together to ensure connection strength.

[0037] The seat bracket provided in this embodiment includes a left seat bracket 9 and a right seat bracket 10. For example... Figures 3-6 As shown, both the left seat bracket 9 and the right seat bracket 10 are U-shaped brackets. The U-shaped sides of the left seat bracket 9 and the right seat bracket 10 are spot-welded to the front seat beam in the front seat beam assembly 7 and the rear seat beam 8 in the rear seat beam assembly 5, respectively. Seat mounting holes and nuts are provided on the upper surfaces of both the left seat bracket 9 and the right seat bracket 10 that are in contact with the floor. The seat 1 is fixed to the left seat bracket 9 and the right seat bracket 10 by bolts.

[0038] Specifically, such as Figure 5 As shown, the floor 2 is drawn to form two convex structures on the left seat bracket 9 and the right seat bracket 10, and the convex structures of the floor 2 form a cavity with the rear seat beam assembly 5; the left seat bracket 9 and the right seat bracket 10 are disposed within the cavity. Similarly, the convex structures of the floor 2 form a cavity with the front seat beam assembly 7, and the seat bracket located in the front seat beam assembly 7 is disposed within the cavity of the front seat beam assembly 7.

[0039] In this embodiment, the upper surface of the convex structure of the floor 2 is horizontal; the upper surfaces of the left seat bracket 9 and the right seat bracket 10 are horizontal and fit against the upper surface of the convex structure of the floor 2. The fit between the convex structure and the surfaces of the left seat bracket 9 and the right seat bracket 10 effectively ensures the bolt connection of the seat. In this embodiment, by fitting the left seat bracket 9 and the right seat bracket 10 with the convex structure of the floor 2, instead of directly stretching the rear seat beam assembly 5, the formability of the rear seat beam assembly 5 is ensured, and the convex structure is prevented from affecting the dimensions of the mounting surface. Furthermore, the seat bracket fits against the upper surface of the convex structure of the floor 2 and is horizontal, ensuring that the seat remains horizontally installed even in structures with raised floors, such as automobiles. This not only facilitates seat installation but also prevents the seat from shearing the bolts under the force of gravity during use, thus preventing bolt breakage. The seat mounting surface remains horizontal even with a raised floor, ensuring the vertical installation and load-bearing capacity of the seat.

[0040] like Figure 4 As shown, the width of the convex structure of the floor 2 is smaller than the width of the floor longitudinal beam 4, so as to avoid affecting the welding of the floor and the floor longitudinal beam 4.

[0041] like Figure 6As shown, the left seat bracket 9 is disposed within the cavity formed by the protruding structure of the floor 2 and the rear seat beam assembly 5, and is inserted into the overlapping portion of the floor 2 and the rear seat beam assembly 5, and is fixedly connected by spot welding of three layers of material. The right seat bracket 10 is disposed within the cavity formed by the protruding structure of the floor 2 and the rear seat beam assembly 5, and is inserted into the overlapping portion of the floor 2 and the rear seat beam assembly 5, and is fixedly connected by spot welding of three layers of material. Similarly, in the front seat beam assembly 7, the seat bracket is also disposed within the cavity and is fixedly connected by spot welding of three layers of material.

[0042] The automotive seat mounting assembly provided in this embodiment of the invention places the seat beam assembly under the floor 2. In the event of sudden braking and tension on the seatbelt, the floor primarily provides a reaction force to the front seat beam assembly 7 and the rear seat beam assembly 5, effectively counteracting the tension of the seatbelt and reducing the load on the weld points of the seat beam assembly, thus significantly reducing the risk of the seat beam assembly being pulled off. Furthermore, the seat beam assembly is inserted into the overlapping area of ​​the floor, floor longitudinal beam 4, and floor sill beam, and is spot-welded with three layers of material. This insertion connection significantly improves the connection strength of the seat beam assembly compared to flanged connections. Moreover, the seat bracket fits flush with the upper surface of the floor's convex structure and is horizontal, ensuring that the seat remains horizontally installed even in structures with raised floors, such as automobiles. This not only facilitates seat installation but also prevents the seat from shearing the bolts under the component of gravity during use, thereby avoiding bolt breakage.
