Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to an automotive seat with a seat spring structure. Background Technology

[0002] With the development of the automotive industry and the improvement of people's living standards, consumers have increasingly higher requirements for the comfort of car seats.

[0003] Traditional car seat cushions often use a fixed support frame. When a car brakes suddenly or collides, the cushion structure is prone to displacement, resulting in a large amount of passenger slippage and posing a risk of passenger slippage. Utility Model Content

[0004] The purpose of this utility model is to provide a car seat with a seat spring structure, which aims to solve the problem that traditional car seat cushions are prone to displacement during sudden braking or collisions, posing a risk of slippage to passengers.

[0005] To achieve the above objectives, this utility model provides a car seat with a seat spring structure, including a backrest, a seat body, a lifting mechanism, a slide rail, and a seat spring mechanism. The backrest is rotatably connected to the seat body and located on one side of the seat body. The lifting mechanism is located at the bottom of the seat body, and the slide rail is located on the side of the lifting mechanism away from the seat body. The seat spring mechanism includes a seat spring body, a welded hook, a linkage mechanism, and a limiting slip. The seat spring body is located on one side of the seat body, the linkage mechanism is located on one side of the seat spring body, the welded hook is fixedly connected to the linkage mechanism and located on the side of the linkage mechanism away from the seat spring body, and the limiting slip is located on one side of the linkage mechanism.

[0006] The limiting latch includes a latch body and a cover plate. The latch body is disposed on one side of the linkage mechanism, and the cover plate is fixedly connected to the latch body and located on the top of the latch body.

[0007] The slide rail includes a slide rail body and a connecting block. The slide rail body is located on the side of the lifting mechanism away from the seat body. The connecting block is threadedly connected to the slide rail body and is located at the bottom of the slide rail body.

[0008] The slide rail also includes a buffer pad, which is mounted on one side of the slide rail body.

[0009] The lifting mechanism includes a rotating link and a drive motor. The rotating link is disposed between the seat body and the slide rail body, and the drive motor is mounted on one side of the rotating link.

[0010] This utility model discloses a car seat with a seat spring structure. The lifting mechanism is used to mechanically drive the seat body to slide on the slide rail and raise the angle. The backrest body can rotate and flatten on the seat body. The seat spring mechanism is used to buffer the impact of the seat body during a collision and reduce the amount of passenger slippage. In the normal sitting posture mode, the welded hook and the connecting rod are rigidly locked, and the compression of the seat spring body is 20mm, providing basic support stiffness (2.5kN / m). During emergency braking (deceleration ≥0.6g), the seat spring body absorbs the impact energy through deformation, and the displacement of the welded hook within the limiting slide buckle is ≤3mm to prevent the passenger from sliding forward. When the backrest is folded down, and the backrest angle is ≥120°, the welded hook disengages from the connecting rod, thereby solving the problem that traditional car seat cushions are prone to displacement and large passenger slippage during emergency braking or collisions, posing a risk of passenger slippage.

Detailed Implementation

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] Please see Figures 1 to 4 This utility model provides a car seat with a seat spring structure, including a backrest 1, a seat body 2, a lifting mechanism 3, a slide rail 4, and a seat spring mechanism 5. The backrest 1 is rotatably connected to the seat body 2 and is located on one side of the seat body 2. The lifting mechanism 3 is located at the bottom of the seat body 2, and the slide rail 4 is located on the side of the lifting mechanism 3 away from the seat body 2. The seat spring mechanism 5 includes a seat spring body 51, a welding hook 52, a linkage mechanism 53, and a limiting slip 54. The seat spring body 51 is located on one side of the seat body 2, the linkage mechanism 53 is located on one side of the seat spring body 51, the welding hook 52 is fixedly connected to the linkage mechanism 53 and is located on the side of the linkage mechanism 53 away from the seat spring body 51, and the limiting slip 54 is located on one side of the linkage mechanism 53.

[0019] In this embodiment, the lifting mechanism 3 is used to mechanically drive the seat body 2 to slide and raise its angle on the slide rail 4. The backrest 1 can rotate and flatten on the seat body 2. The seat spring mechanism 5 is used to buffer the impact of the seat body 2 during a collision and reduce the amount of passenger slippage. In the normal sitting posture mode, the welded hook 52 is rigidly locked to the connecting rod, and the compression of the seat spring body 51 is 20mm, providing basic support stiffness (2.5kN / m). During emergency braking (deceleration ≥0.6g), the seat spring body 51 absorbs the impact energy through deformation, and the displacement of the welded hook 52 within the limiting slip buckle 54 is ≤3mm to prevent the passenger from sliding forward. When the backrest 1 is in the lowered mode, and the angle of the backrest 1 is ≥120°, the welded hook 52 disengages from the connecting rod, thereby solving the problem that traditional car seat cushions are prone to displacement and large passenger slippage during emergency braking or collisions, posing a risk of passenger slippage.

[0020] Furthermore, the limiting slider 54 includes a slider body 541 and a cover plate 542. The slider body 541 is disposed on one side of the linkage mechanism 53, and the cover plate 542 is fixedly connected to the slider body 541 and located on the top of the slider body 541.

[0021] In this embodiment, the cover plate 542 is fixed to the sliding buckle body 541 by bolts, thereby assembling the sliding buckle body 541 to the linkage mechanism 53. The displacement of the welding hook 52 within the sliding buckle body 541 is ≤3mm, preventing the passenger from sliding forward.

[0022] Furthermore, the slide rail 4 includes a slide rail body 41 and a connecting block 42. The slide rail body 41 is disposed on the side of the lifting mechanism 3 away from the seat body 2. The connecting block 42 is threadedly connected to the slide rail body 41 and is located at the bottom of the slide rail body 41.

[0023] In this embodiment, the connecting block 42 is used to fix the slide rail body 41 inside the carriage. The slide rail body 41 allows the seat body 2 to slide back and forth to adjust its position.

[0024] Furthermore, the slide rail 4 also includes a buffer pad 43, which is fitted onto one side of the slide rail body 41.

[0025] In this embodiment, the buffer pad 43 is provided to reduce the impact noise when the seat body 2 is lifted.

[0026] Furthermore, the lifting mechanism 3 includes a rotating link 31 and a drive motor 32. The rotating link 31 is disposed between the seat body 2 and the slide rail body 41, and the drive motor 32 is mounted on one side of the rotating link 31.

[0027] In this embodiment, the drive motor 32 is driven by a controller, which in turn drives the rotating link 31 to rotate, and the rotation of the rotating link 31 drives the seat body 2 to rise.

[0028] The above-disclosed embodiment is merely a preferred embodiment of a car seat with a seat spring structure, and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments, and equivalent variations made in accordance with the claims of this application, still fall within the scope of this application.
