Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, specifically a lightweight automotive seat frame assembly structure. Background Technology

[0002] Car seats are an important component of automobiles. With the rapid development of technology, car seats have made great progress compared to the past. The current development direction of car seats is lightweighting, intelligence, and safety. Conventional seat frames are mainly metal structures, which are excellent in terms of support and stability. However, the metal structure and filling materials make the overall weight of car seats remain high. In order to reduce structural weight, current car seats mainly use aluminum alloy materials, carbon fiber materials, or one-piece injection molding for lightweight design. However, lightweight design brings a problem: the support of the seat can only be provided by the soft padding. In this way, during use, not only will the comfort of the seat be reduced, but the support of the soft padding will also decrease with long-term sitting, causing the seat to collapse due to compression, which is not conducive to driving. In view of this, this case was developed through in-depth research on the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] Please see Figure 1-3This utility model provides an implementation scheme: In the application of modern car seats, current car seats mainly use aluminum alloy materials, carbon fiber materials, or one-piece injection molding to reduce structural weight. However, the lightweight design brings a problem: the support of the seat can only be provided by the soft padding. In this way, during the application, not only will the comfort of the seat be reduced, but the support of the soft padding will also decrease with compression after long-term sitting, causing the seat to collapse, which is not conducive to driving.

The bottom frame 1 is a rectangular alloy frame made of high-strength aluminum alloy casting. The frame wall thickness adopts a gradually thickened design. A pair of pins 3 on both sides are surface hardened and hinged to the backrest frame 2 to achieve multi-angle adjustment.

[0020] The backrest frame 2 is a one-piece molded plastic structure frame, which is made of reinforced engineering plastic injection molding. It has a biomimetic rib support structure inside to improve longitudinal bending resistance and lateral torsional resistance. Support cushions 4 and control plates are respectively set on both sides of the backrest frame 2.

[0021] The support cushion 4 adopts an ergonomic design to provide support for people. The control panel is connected to an external air pressure controller 8, and the support of the support cushion 4 can be adjusted through the air pressure controller 8.

[0022] According to the instruction manual Figure 1-3 It can be seen that the integrated design of the main control board 6 and the backrest frame 2 optimizes the gas pipeline layout and significantly reduces pressure loss.

[0023] According to the instruction manual Figure 1-3 It can be seen that the support cushion 4 adopts a three-layer composite structure. The outer layer of memory foam provides deformation cushioning, the middle layer of three-dimensional fabric realizes pressure distribution, and the inner layer of matrix spring array constitutes the basic support unit. Each spring unit has a built-in elastic control column 7. The column body of the elastic control column 7 is composed of a combination of flexible corrugated tube and rigid guide rod. The end is connected to the inner wall of the support cushion 4 through a fixing plate. The overall support of the support cushion 4 is adjusted by the extension and retraction of the elastic control column 7.

[0024] As a preferred option, the bottom of the bottom frame 1 is further equipped with a pair of steel structure mounting sliders 9, which significantly reduces weight while maintaining high load-bearing capacity; the connection between the bottom frame 1 and the mounting sliders 9 adopts a biomimetic interlocking pattern design, combined with a special surface treatment process to reduce sliding friction resistance.

[0025] As a preferred option, the backrest frame 2 is seamlessly connected to the main control board 6, a transition layer is used at the interface to eliminate assembly stress, and honeycomb heat dissipation holes are set on the surface to optimize airflow channels.

[0026] As a preferred option, the main control board 6 is a flow distribution device with an internal cavity structure. The main cavity receives high-pressure gas delivered by an external air pump through a pipeline. Since the cavity of the elastic control column 7 is connected to the cavity of the main control board 6, under the action of balancing support pressure, it enables...

[0027] As a preferred option, the elastic control column 7 is connected through the center of the spring 5, and multi-level stiffness adjustment is achieved by gas pressure drive. The combination design of the bellows and guide rod takes into account both motion flexibility and structural durability.

[0028] As a preferred option, the air pressure controller 8 further includes a control air pump 81 and a control tube 82. The output pressure of the control air pump 81 is adjustable, and the control tube 82 adopts a multi-layer composite structure to ensure transmission stability. The mechanical control valve 83 is used to close the main control board to ensure stable air pressure.

[0029] This application utilizes a composite frame structure to significantly improve support performance while ensuring the seat is lightweight. The combination of a high-strength alloy frame and a biomimetic plastic frame reduces weight and enhances overall rigidity. Combined with an adjustable air pressure distribution system, the seat support can respond quickly to riding needs. The composite backrest works in tandem with the rigid support unit through a flexible buffer layer to effectively distribute pressure and suppress deformation over long-term use, providing drivers and passengers with lasting and stable comfort support.
