Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to an automotive seat frame assembly with adjustment and support functions. Background Technology

[0002] The car seat frame assembly is suitable for the front and rear seats of various models such as sedans, SUVs, and MPVs. It can realize multi-dimensional adjustment of seat back angle, seat cushion height and lumbar support to adapt to the seating needs of users of different heights and body types, and improve the comfort and safety of driving and riding.

[0003] The car seat frame is the core load-bearing structure of the seat, and its adjustability and support performance directly affect the user's riding experience and health. Currently, existing car seat frames have the following problems: most traditional seat frames only support one-way adjustment of the backrest angle and the fore-and-aft sliding of the seat cushion, lacking adjustment of the seat cushion height. When facing drivers of different heights, it is easy for shorter people to not be able to see the road ahead, while taller people may touch the roof due to excessive height. This reduces the flexibility of car seat adjustment and limits the adjustment dimensions. Therefore, a car seat frame component with adjustment and support functions is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a car seat frame assembly with adjustable and support functions, which can solve the technical problem that the height of existing car seats cannot be flexibly adjusted, resulting in short people not being able to see the front clearly, and tall people being too tall and contacting the roof.

[0006] To solve the above-mentioned technical problems, this utility model provides a car seat frame assembly with adjustment and support functions, adopting the following technical solution: It includes a seat frame, inside which a seat cushion frame is provided. An adjustment structure is provided between the seat frame and the seat cushion frame. The adjustment structure includes an adjustment motor fixedly installed inside the seat frame. An adjustment screw is fixedly connected to the output end of the adjustment motor. A limit block is threadedly connected to the outer wall of the adjustment screw, and a guide cylinder is fixedly installed on the outer wall of the limit block. The guide cylinder is fixedly installed on the outer wall of the seat cushion frame. A pressure sensor is fixedly installed inside the seat cushion frame. Connecting plates are fixedly installed on both sides of the outer wall of the seat frame, and a seat back frame is rotatably installed on the outer wall of the other end of the connecting plates. A headrest is fixedly installed at the upper end of the seat back frame. Adjustment knobs are rotatably connected to the outer walls of both connecting plates. A movable structure is provided below the seat frame.

[0007] Optionally, guide grooves are provided on both sides of the seat frame, and the adjusting motor and adjusting screw are both located inside the guide grooves.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] The following is in conjunction with the appendix Figure 1 —4. This utility model will be described in further detail.

[0019] Reference Figure 1-4 In this embodiment, in order to solve the technical problem that the height of existing car seats cannot be flexibly adjusted, resulting in short people not being able to see the front clearly, and tall people being too tall and contacting the roof of the car, this utility model discloses a car seat frame assembly with adjustment and support functions. The seat includes a seat frame 1, a seat cushion frame 2 inside the seat frame 1, an adjustment structure 3 between the seat frame 1 and the seat cushion frame 2, an adjustment motor 31 fixedly installed inside the seat frame 1, an adjustment screw 32 fixedly connected to the output end of the adjustment motor 31, a limit block 33 threadedly connected to the outer wall of the adjustment screw 32, and a guide cylinder 34 fixedly installed on the outer wall of the limit block 33, the guide cylinder 34 fixedly installed on the outer wall of the seat cushion frame 2, a pressure sensor 4 fixedly installed inside the seat cushion frame 2, connecting plates 71 fixedly installed on both sides of the outer wall of the seat frame 1, and a seat back frame 5 rotatably installed on the outer wall of the other end of the connecting plates 71, a headrest 9 fixedly installed on the upper end of the seat back frame 5, and adjustment knobs 7 rotatably connected to the outer walls of both connecting plates 71, and a moving structure 8 below the seat frame 1. Specifically, the seat frame 1 has guide grooves 35 on both sides inside, the adjusting motor 31 and the adjusting screw 32 are both set inside the guide grooves 35, and there are two guide cylinders 34 in total, and the outer walls of the two guide cylinders 34 are slidably connected to the inside of the fixed slide rod 36.

[0020] By sliding one of the guide cylinders 34 to the outside of the adjusting screw 32, it is convenient to guide the movement of the seat frame 2. Specifically, the fixed slide bar 36 is fixedly installed inside another guide groove 35, and two electromagnetic shock absorbers 6 are fixedly installed inside the seat back frame 5.

[0021] The pressure sensor 4 is a flexible pressure sensor, model FSR402. The electromagnetic shock absorbers 6 are evenly installed on the support beam of the seat back frame 5 and electrically connected to the pressure sensor 4. When excessive pressure is detected in a certain area, the electromagnetic shock absorber 6 automatically reduces the damping coefficient and increases the support elasticity. When the pressure is too low, the damping coefficient is increased to enhance the support force, achieving dynamic adaptation. In addition, the memory foam support pad is covered on the outside of the pressure sensor 4 to further improve comfort. Specifically, the movable structure 8 includes a support base 81 fixedly installed at the bottom of the seat frame 1. A mounting bracket 82 is provided below the support base 81 and is installed on the car base. There are two mounting brackets 82 in total, and a positioning plate 83 is fixedly installed inside each of the two mounting brackets 82.

[0022] By fixing the mounting bracket 82 to the car base and sliding the support base 81 within the mounting bracket 82, the position of the seat frame 1 can be easily adjusted to accommodate users with different leg lengths. Specifically, an adjusting cylinder 84 is fixedly installed on the outer wall of each of the two positioning plates 83, and a guide block 85 is fixedly installed on one end of each of the two adjusting cylinders 84. There are two sets of guide blocks 85, and an mounting plate 86 is fixedly installed on the outer wall of each set of guide blocks 85. A guide rod 87 is fixedly installed between the two sets of mounting plates 86.

[0023] Two adjusting cylinders 84 drive the mounting plate 86 on the guide block 85 to move along the limiting slide groove 89, and the two mounting plates 86 drive the support base 81 on the guide rod 87 to move when they move.

[0024] Specifically: two guide rods 87 are fixedly installed inside the support base 81. Two sets of limiting slide grooves 89 are opened on both sides inside the mounting bracket 82. Two sets of guide blocks 85 are slidably connected inside the limiting slide grooves 89. Slide rails 88 are fixedly installed inside the two mounting brackets 82 below the guide blocks 85, and the guide blocks 85 are slidably connected to the slide rails 88.

[0025] By setting a limiting groove 89, the two mounting plates 86 can drive the guide block 85 to slide and limit within the limiting groove 89. At the same time, a slide rail 88 is set so that the two sets of guide blocks 85 can slide and cooperate on the slide rail 88 when moving, which makes the seat frame 1 relatively stable when moving.

[0026] The specific working principle is as follows: When users of different heights drive, the limit block 33 on the outside of the adjusting screw 32 moves according to the user's height via the drive adjustment motor 31. This causes the limit block 33 to move the seat cushion frame 2 on the guide cylinder 34 to adjust its height. At the same time, the other side of the seat cushion frame 2 slides on the outside of the fixed slide rod 36 via the guide cylinder 34, facilitating flexible height adjustment of the seat cushion frame 2 and improving driving comfort for users of different heights. Simultaneously, rotating the two adjustment knobs 7 on the outside of the connecting plate 71 causes the adjustment knobs 7 to move the seat cushion frame 2 to adjust its height. The seat back frame 5 rotates at an angle to allow the driver to lie down and rest. At the same time, it drives the adjusting cylinders 84 on the outer side of the positioning plate 83 inside the two mounting brackets 82 to work. This causes the two adjusting cylinders 84 to move the guide rods 87 on the outer mounting plate 86 of the guide block 85. The guide rods 87 then move the seat frame 1 on the support base 81 forward. Meanwhile, when the support base 81 moves, it uses another guide rod 87 to slide in the limiting groove 89 inside the mounting bracket 82, which facilitates flexible forward and backward movement of the seat and enables multi-position adjustment of the seat.
