Description

Technical Field

[0001] This utility model relates to a car seat frame reinforcement structure, belonging to the field of car seat frame reinforcement technology. Background Technology

[0002] In the context of the automotive industry's continuous pursuit of lightweight design, high safety, and comfort, the automotive seat frame, as a core component supporting passengers, plays a decisive role in the overall vehicle safety and riding experience. Currently, reinforcing the structure with ribs is a common technical means to enhance seat strength. By adding reinforcing ribs to key parts of the frame, stress can be effectively distributed, improving the overall load-bearing capacity of the frame.

[0003] While existing reinforcing rib structures in current automotive seat frame designs can provide a certain degree of support and reinforcement during daily use, they have significant limitations in practical applications. Specifically, existing reinforcing rib structures typically have relatively fixed shapes and dimensions, making it difficult to flexibly adjust them to different specifications and sizes of automotive seat frames. Therefore, when faced with different models of automotive seat frames, this reinforcement structure often struggles to achieve precise fit, greatly limiting its applicability and reducing its versatility and flexibility in actual production, thus limiting the use of the reinforcement structure.

[0004] Furthermore, the existing connection methods between reinforcing ribs and car seat frames are mostly rigid. This connection method lacks necessary cushioning mechanisms and cannot effectively absorb and disperse external impact forces. During daily use, car seats may be subjected to bumps or impacts for various reasons. When the impact force exceeds the strength limit of the reinforcing rib structure itself, the reinforced structure is prone to deformation or even damage. This deformation not only reduces the overall strength and stability of the seat frame but may also cause accidental injury to the driver, thus exposing the serious deficiencies in the protective capabilities of existing reinforcing rib structures, ultimately rendering the reinforced structure inadequate in terms of safety. Summary of the Invention

[0005] In view of the shortcomings of the prior art, this utility model provides a car seat frame reinforcement structure, which overcomes the shortcomings of the prior art and effectively solves the problems of the limitations in the use of reinforcement structures and the insufficient protection of reinforcement structures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A car seat frame reinforcement structure includes four support frames, each of which has a fixed frame fixed to its proximal end, and the proximal ends of the four fixed frames are rotatably connected to a hinge frame.

[0008] A connecting structure is provided at the near ends of each pair of adjacent support frames, and four fixing blocks are provided on the connecting structure; the connecting structure can move in opposite directions along its own length with each pair of adjacent fixing blocks in order to adjust the size of the reinforcing structure of the car seat frame.

[0009] Preferably, the connection structure includes four fixing blocks, each fixing block has a groove in the middle, each groove has a sliding plate slidably connected to its inner wall, each pair of adjacent sliding plates has a bidirectional threaded rod fixed to their adjacent sides, and each bidirectional threaded rod has a handle fixed to its middle.

[0010] Preferably, each pair of adjacent fixed blocks is fixed at opposite ends to the adjacent two fixed frames on the same side, the outer surface of each slide is slidably connected to the inner wall of each slide groove, and the vertical cross-section of each slide is circular.

[0011] Preferably, each of the bidirectional threaded rods is fixed at both ends to the middle of the two adjacent sides of the slide plates, and the outer surfaces of both sides of each bidirectional threaded rod are threaded to the adjacent ends of two adjacent fixed blocks, and the middle of each handle is fixed to the middle of each bidirectional threaded rod.

[0012] Preferably, each of the four support frames has a stabilizing groove on its disjointed side, a stabilizing block is slidably connected to the inner wall of each stabilizing groove, a spring is fixed to one side of each stabilizing block, a connecting frame is fixed to the other side of each stabilizing block, and a welding frame is fixed to the other end of each connecting frame.

[0013] Preferably, the four stabilizing slots extend through the four opposing sides of the support frame, the outer surface of each stabilizing block is slidably connected to the inner wall of each stabilizing slot, the vertical cross-section of each stabilizing block is square, the four springs are fixed at their proximal ends to the inner walls of the proximal ends of the four stabilizing slots, and the four springs are fixed at their opposing ends to the proximal sides of the four stabilizing blocks.

[0014] Preferably, the four connecting frames are fixed at their proximal ends to the four stabilizing blocks at their disjoint ends, the four connecting frames are fixed at their disjoint ends to the four welding frames at their proximal ends, and the outer surfaces of the four connecting frames are slidably connected to the inner walls of the four stabilizing grooves at their disjoint ends.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The car seat frame reinforcement structure allows for manual rotation of two handles in opposite directions, enabling the support frame, fixing frame, hinge frame, fixing block, slide groove, slide plate, two-way threaded rod, and handle to work together to achieve an adjustable size. This allows for adjustments based on the actual dimensions of the car seat frame, thereby improving the versatility of the reinforcement structure.

[0017] 2. The reinforced structure of this car seat frame allows for simultaneous reverse rotation of two handles by hand, enabling the stabilizing groove, stabilizing block, spring, connecting frame, and welding frame to work together to achieve a force buffering effect. This prevents excessive impact from causing excessive deformation of the overall structure and thus avoiding injury to the driver, thereby improving the protective performance of the reinforced structure.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example

[0024] This utility model provides a reinforced structure for an automotive seat frame.

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The system includes four support frames 1, which support the overall reinforced structure. Each of the four support frames 1 has a fixed frame 2 at its adjacent ends, which provides support for adjusting the bidirectional threaded rod 7. The four fixed frames 2 are rotatably connected to a hinge frame 3 at their adjacent ends. The hinge frame 3 can be adjusted according to the size of different car seat frames. For example, when facing a car seat frame that is wider on the left and right and shorter in front and back, the hinge frame 3 can be adjusted to unfold; when facing a car seat frame that is narrower on the left and right and longer in front and back, the hinge frame 3 can be adjusted to fold, to accommodate different sized car seat frames. A connecting structure is provided at the adjacent ends of every two adjacent support frames 1. The connecting structure includes four fixed blocks 4, each fixed block 4 having a groove 5 in the middle. A sliding plate 6 is slidably connected to the inner wall of each groove 5. A bidirectional threaded rod 7 is fixed to the adjacent sides of every two adjacent sliding plates 6, and a handle 8 is fixed to the middle of each bidirectional threaded rod 7.

[0026] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that each pair of adjacent fixed blocks 4 are fixed at opposite ends to each pair of adjacent fixed frames 2, the outer surface of each slide 6 is slidably connected to the inner wall of each slide groove 5, the vertical cross-section of each slide 6 is circular, the two ends of each bidirectional threaded rod 7 are fixed to the middle of the two slide 6, the outer surfaces of each bidirectional threaded rod 7 are threaded to the near ends of the two adjacent fixed blocks 4, and the middle of each handle 8 is fixed to the middle of each bidirectional threaded rod 7.

[0027] In use, this invention involves manually rotating two handles 8 simultaneously in opposite directions, maintaining consistent rotation. This causes the bidirectional threaded rod 7, fixed to the center of the two handles 8 and with opposite thread directions, to rotate in the opposite direction. The bidirectional threaded rod 7, with its two opposite thread directions and counter-rotating rotation, drives four fixed blocks 4 connected to its outer surface by threads. These blocks move in the opposite direction under the limiting action of the support frame 1, the fixed frame 2 fixed to the support frame 1, and the hinge frame 3. This counter-movement of the four fixed blocks 4 allows for size adjustment, enabling adjustments based on the actual dimensions of the car seat frame, thereby improving the versatility of the reinforced structure. Example

[0028] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Based on Embodiment 1, a force-bearing buffer function has been added;

[0029] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4It is worth noting that each of the four support frames 1 has a stabilizing groove 9 on its opposite side. Each stabilizing groove 9 has a slidably connected stabilizing block 10 on its inner wall. Each stabilizing block 10 has a spring 11 fixed on one side and a connecting frame 12 fixed on the other side. Each connecting frame 12 has a welding frame 13 fixed at its other end.

[0030] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that four stabilizing grooves 9 pass through the four support frames 1 on opposite sides. The outer surface of each stabilizing block 10 is slidably connected to the inner wall of each stabilizing groove 9. The vertical cross-section of each stabilizing block 10 is square. The near ends of four springs 11 are fixed to the inner walls of the near ends of the four stabilizing grooves 9, and the far ends of four springs 11 are fixed to the near sides of the four stabilizing blocks 10. The near ends of four connecting frames 12 are fixed to the far sides of the four stabilizing blocks 10, and the far ends of four connecting frames 12 are fixed to the near sides of the four welding frames 13. The outer surfaces of the four connecting frames 12 are slidably connected to the inner walls of the far sides of the four stabilizing grooves 9.

[0031] In use, this invention involves simultaneously rotating two handles 8 in opposite directions manually, maintaining consistent rotation, so that the handles 8 drive the connected bidirectional threaded rod 7 to rotate synchronously. Through the fixing block 4 threaded onto the bidirectional threaded rod 7, and under the limiting constraints of the support frame 1 and the fixing frame 2, the opening and closing angle of the hinge frame 3 is precisely adjusted. During adjustment, the connecting frame 12, which is slidably connected to the inner wall of the stabilizing groove 9 in the middle of the support frame 1, drives the welding frame 13 fixed at its other end to gradually abut against the car seat frame.

[0032] As the handle 8 is continuously rotated, the welding bracket 13 pushes the stabilizing block 10 to compress the spring 11 via the connecting bracket 12. The spring 11 retains a certain elastic buffer space when compressed. At this time, the compressed spring 11 generates elastic force through its elastic deformation, stably and firmly pressing the welding bracket 13 onto the surface of the car seat frame. Finally, the four welding brackets 13 are welded to the car seat frame. This structural design not only strengthens the overall strength of the frame but also utilizes the compression deformation characteristics of the spring 11 to buffer external impacts, achieving a force-bearing buffering effect. This prevents excessive impact from causing excessive deformation of the overall structure and thus avoiding injury to the driver, thereby improving the protective performance of the reinforced structure.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
