Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to a seat support structure and a seat. Background Technology

[0002] The seat support structure is a key component of the overall automotive seat structure, directly affecting passenger comfort and safety. In existing technologies, automotive seat support structures are typically unibody sheet metal structures or stamped steel sheet structures. Using uniformly thick carbon steel sheet metal for stamping results in high weight, low material utilization, and complex processing, hindering overall vehicle lightweighting and increasing production costs. Some technical solutions reduce weight by using aluminum alloys or composite materials, but these lack sufficient load-bearing capacity and durability, and some support structures deform during high-speed collisions, affecting seat fixation strength. Therefore, there is an urgent need for a seat support structure that can balance strength and lightweight design. Utility Model Content

[0031] refer to Figure 1 , Figure 1 This application provides a seat support structure, which includes a support plate 1 with a hollow structure 11 and a support member 2 with a flanged structure. The support member 2 is fixedly connected to both sides of the support plate 1. The support member 2 has an upper end face 21 and a lower end face 22 at both ends. The upper end face 21 can be connected to the seat body 5, and the lower end face 22 can be connected to the floor. In this way, by setting the support plate 1 with the hollow structure 11, part of the non-load-bearing structure can be removed, and the weight of the support plate 1 can be reduced without affecting the mechanical strength of the support plate 1. The support member 2 with the flanged structure is fixedly connected to both sides of the support plate 1. Compared with traditional tubular support structures and solid support structures, the support member 2 with the flanged structure has a smaller structural weight while ensuring support stability, which is conducive to reducing the overall weight of the seat support structure and realizing the lightweight design of the seat support structure.

[0032] In some embodiments, the seat support structure can be fixedly connected to the seat body 5 via its upper end face 21, and can also be fixedly connected to the floor via its lower end face 22. For example, the fixed connection can be made by welding. In other embodiments, the upper end face 21 and lower end face 22 of the support member 2 are respectively provided with connecting structures, and the seat support structure can be detachably connected to the seat body 5 and the floor via the connecting structures. It is understood that the detachable connection can be, but is not limited to, one of screw connection, pin connection and snap-fit ​​connection.

[0033] Specifically, the support member 2 includes a first support member 6 and a second support member 7. The first support member 6 and the second support member 7 are respectively disposed on both sides of the support plate 1. In this way, the strength of the seat support structure can be improved, which is conducive to improving the structural stability of the seat support structure.

[0034] Specifically, the support plate 1 and the support member 2 form an open cavity after being connected, which can reduce redundant materials, avoid occupying the space under the seat, and improve the utilization rate of the space under the seat.

[0035] In a possible implementation, the sidewall of the support member 2 has a preset angle with the upper surface 21, which is 80°-100°. It is understood that the preset angle between the sidewall of the support member 2 and the upper surface 21 can be any value between 80° and 100°, and will not be enumerated here. It is understood that the longitudinal tilt angle of the support member 2 is 0-10°. Thus, the support member 2 is an inclined structure relative to the seat bottom, which saves space occupied by the seat support structure, expands the space available for passenger footing, and improves passenger comfort. Preferably, the preset angle between the sidewall of the support member 2 and the upper surface 21 is 80°, allowing the support member 2 to expand the space under the seat while providing strong support.

[0036] Specifically, the first support member 6 and the second support member 7 are arranged in parallel. Preferably, refer to Figure 2 The angle between the side wall of the first support member 6 and the upper end face 21 is 80°, and the angle between the side wall of the second support member 7 and the upper end face 21 is 100°. In this way, the seat support structure can have stable support performance and improve the utilization rate of the space under the seat, making it convenient for passengers to place their feet.

[0037] In a possible implementation, the support plate 1 is a parallelogram structure with interior angles of 80°-100°. Understandably, the interior angles of the parallelogram structure can be any value between 80° and 100°. The interior angle of the support plate 1 matches the included angle between the side wall and the upper end face 21 of the support member 2, which is beneficial for the assembly between the support plate 1 and the support member 2, thereby reducing assembly errors.

[0038] In a possible implementation, a reinforcing frame 12 is provided at the edge of the hollow structure 11. This improves the local strength of the support plate 1, and by providing a smaller reinforcing structure, the rigidity of the support plate 1 can be increased while achieving weight reduction. Specifically, the reinforcing frame 12 and the support plate 1 are integrally formed, avoiding unnecessary connection points and helping to prevent stress concentration.

[0039] Specifically, the edge of the hollow structure 11 is a concave structure that is recessed into the open cavity relative to the plane of the support plate 1, as shown in the reference. Figure 3 , Figure 3 The diagram shows a perspective view of the seat support structure on one side of the support member 2. It can remove the non-load-bearing area material while retaining the high-stress area at the edge of the hollow structure 11, which is beneficial to improving the strength of the edge of the hollow structure 11.

[0040] In a possible implementation, the flange structure has an arc-shaped cross-section, as shown in the reference. Figure 4 , Figure 4This is a side view of a seat support structure provided in an embodiment of this application. Setting the flange structure of the support member 2 to an arc shape helps to disperse stress and improve the stability of the support member 2; furthermore, the smooth, rounded outer surface of the arc-shaped structure helps to prevent injury from accidental bumps.

[0041] In a possible implementation, the thickness of the support plate 1 gradually decreases from the hollow structure 11 to the edge of the support plate 1. This enhances the support strength of the support plate 1 at the hollow structure 11, reduces the thickness of the support plate 1 at the connection between the support plate 1 and the support member 2, and effectively utilizes materials, achieving a lightweight design while ensuring the load-bearing performance of the seat support structure.

[0042] In a possible implementation, the seat support structure further includes a first connector 3, which is fixedly connected to the upper end face 21, as shown in the reference. Figure 4 The seat support structure is detachably connected to the seat body 5 via the first connector 3. This increases the contact area between the seat support structure and the seat bottom, which helps to distribute the pressure on the seat support structure, avoids localized stress concentration, and improves the bonding strength between the seat support structure and the seat. Specifically, the connection between the first connector 3 and the upper surface 21 can be welded. Understandably, the connection method between the first connector 3 and the upper surface 21 can be adjusted according to actual application requirements.

[0043] In a possible implementation, the first connector 3 has a first connecting plate 32 and a second connecting plate 33. The first connecting plate 32 is fixedly connected to the support plate 1, and the second connecting plate 33 can be connected to the seat body 5. (Refer to...) Figure 5 , Figure 5 A cross-sectional schematic diagram of the first connector 3 in an embodiment of this application is shown. This increases the contact area between the first connector 3 and the support plate 1, thereby improving the bonding strength between the first connector 3 and the support plate 1. Specifically, the second connector 33 has a first rolled edge structure, which enhances the bending resistance of the second connector 33, thereby improving the mechanical strength of the first connector 3.

[0044] In a possible implementation, the seat support structure further includes a second connector 4, which is fixedly connected to the lower end face 22. The seat support structure is detachably connected to the floor via the second connector 4. Thus, by providing the second connector 4, the contact area between the seat support structure and the floor can be increased, avoiding localized stress concentration on the floor and preventing damage from increased pressure. Furthermore, it helps to improve the bonding strength between the seat support structure and the floor, thereby enhancing the stability of the seat support structure. Specifically, the connection between the second connector 4 and the lower end face 22 can be achieved by welding. Understandably, the connection method between the second connector 4 and the lower end face 22 can be adjusted according to actual application requirements.

[0045] Specifically, the second connector 4 has a third connecting plate 42 and a fourth connecting plate 43. The third connecting plate 42 is fixedly connected to the support plate 1, and the fourth connecting plate 43 can be connected to the floor. (Refer to...) Figure 6 , Figure 6 A cross-sectional schematic diagram of the second connector 4 in one embodiment of this application is shown. Thus, by providing the third connecting plate 42, the contact area between the second connector 4 and the support plate 1 can be increased, thereby improving the bonding strength between the second connector 4 and the support plate 1.

[0046] In some embodiments, the third connecting plate 42 has a second rolled edge structure, which enhances the bending resistance of the third connecting plate 42 and thus improves the mechanical strength of the second connecting member 4. Specifically, the fourth connecting plate 43 has a third rolled edge structure, which helps to improve the bending resistance of the fourth connecting plate 43 and thus improves the structural strength and impact resistance of the seat support structure.

[0047] In a possible implementation, the first connector 3 is provided with spaced-apart first connecting holes 31, and the second connector 4 is provided with spaced-apart second connecting holes 41. Thus, the first connecting holes 31 and the second connecting holes 41 can serve as positioning holes to align the seat support structure with the bottom of the seat body 5 and with the floor. Furthermore, the connecting holes enable detachable connections between the seat support structure and the seat body 5, and between the seat support structure and the floor.

[0048] Specifically, the connection between the first connector 3 and the seat body 5 is a threaded connection. The bottom of the seat body 5 has a first threaded hole that matches the position of the first connecting hole 31. The first threaded fastener can connect to the first threaded hole after passing through the first connecting hole 31, thereby realizing the connection between the first connector 3 and the seat body 5.

[0049] Specifically, the connection between the second connector 4 and the floor can be a threaded connection. The floor has a second threaded hole that matches the position of the second connection hole 41. The second threaded fastener can be connected to the second threaded hole after passing through the second connection hole 41, thereby realizing the connection between the second connector 4 and the seat body 5.

[0050] In a possible implementation, the support plate 1 and the support member 2 are made of SG700BL2.0 steel. Compared with traditional carbon steel sheet metal, SG700BL2.0 steel has a higher yield strength, which is greater than or equal to 700MPa. It can achieve the same load-bearing capacity as carbon steel sheet metal with a smaller thickness, which is beneficial to achieving the lightweight of support plate 1 and support member 2.

[0051] In a possible implementation, the material of the first connector 3 can be SG700BL3.0 steel, and the material of the second connector 4 can be SG700BL3.0 steel. Specifically, the support member 2, the support plate 1, the first connector 3, and the second connector 4 can be made of the same material or different materials. The materials used in each part of the seat support structure can be adjusted according to the actual application requirements to meet the lightweight design.

[0052] In a possible implementation, the weight of the seat support structure is 1-1.8 kg. It is understood that the weight of the seat support structure can be any value within the range of 1-1.8 kg, and will not be enumerated here. Compared with traditional seat support structures, the seat support structure provided in this application embodiment has a smaller weight, which is beneficial for reducing the weight of the seat and achieving a lightweight design for the entire seat.

[0053] On the other hand, this application provides a seat, including a seat body 5 and a seat support structure as described above. Using the seat support structure provided in this application embodiment enables a lightweight design of the entire seat, while simultaneously improving seat stability and reducing production costs.

[0054] In a possible implementation, the seat support structure is located below the seat body 5, and the seat body 5 is connected to the floor via the seat support structure, as shown in the reference. Figure 7 , Figure 7 A schematic diagram illustrating the connection between the seat body 5 and the seat support structure is shown. The seat support structure provides support for the seat body 5 and bears the weight of the seat body 5 and the passenger. Furthermore, by connecting the seat body 5 to the floor through the seat support structure provided in this application, a detachable connection between the seat body 5 and the floor can be achieved, thereby enabling modular manufacturing of the seat. Preferably, at least two seat support structures are spaced apart below the seat body 5.

[0055] Specifically, a foot pedal is provided at the bottom of the seat body 5, and the seat support structure and the foot pedal are arranged to avoid each other, so as to optimize the space under the seat and improve the utilization rate of the space under the seat.
