[0002] The main frame of an automotive seat is the core safety structure and load-bearing base of the seat assembly, and its performance directly affects the comfort and safety of occupants and the vehicle's energy efficiency. To meet the increasingly stringent requirements of the modern automotive industry for energy conservation, environmental protection, and safety, we have innovatively introduced a lightweight, hollowed-out reinforcing rib structure, revolutionizing the traditional main frame of the seat. This structure achieves significant weight reduction while ensuring and even improving mechanical performance, making it an ideal choice for next-generation intelligent cockpits and new energy vehicles. However, existing automotive seat main frames with lightweight hollowed-out reinforcing rib structures still have certain shortcomings. While traditional car seat frames with lightweight hollow reinforcing ribs can be used effectively, they often use solid or thick plate structures and lack effective lightweight design, resulting in a large overall weight, which is detrimental to vehicle fuel efficiency and performance. The cushioning structure is simple, often relying solely on seat cushion foam, and lacks an effective suspension cushioning mechanism, resulting in poor shock absorption and a stiff riding experience, which often bothers users.

[0018] A slide plate 204 is fixedly installed on the bottom surface of the base 102. The bottom surface of the slide plate 204 is slidably connected to the inside of the slide rail 202. Four sets of fixing brackets 201 are fixedly installed on the bottom surface of the slide rail 202. Two sets of slide rails 202 are fixedly connected by two support plates 203.

[0019] A pull rod 205 is connected to the slide 204, and multiple sets of buckles 206 are provided on the slide rail 202. The pull rod 205 and the buckles 206 are used together to engage.

[0020] A fixed shaft 301 and a support shaft 302 are fixedly installed between two sets of fixed seats 101. The fixed shaft 301 is located to the left of the support shaft 302. A fixed ring 303 is fixedly installed on the support shaft 302. A hook 304 is sleeved on the outside of the fixed ring 303.

[0024] Working principle: When using a car seat main frame with a lightweight hollow reinforcing rib structure, the adjustment, movement and cushioning functions of the seat are realized through the coordinated work of the three main parts: the main body 1, the moving mechanism 2 and the buffering mechanism 3. The backrest 104 is rotatably connected to the fixed base 101 via the pivot 103. With the help of the torsion spring 105, the backrest angle can be adjusted and automatically reset, which can meet the daily needs of the user. When the user needs to adjust the position of the seat, the backrest position can be adjusted and locked by the cooperation of the pull rod 205 and the buckle 206. When unlocking, the sliding connection between the slide plate 204 and the slide rail 202 allows the slide plate 204 to slide within the slide rail 202 to adjust the position of the seat. After the adjustment is completed, the pull rod 205 is lifted to lock the position by cooperating with the buckle 206. In the buffer mechanism 3, the fixed plate 305 and the frame 306 are connected by a spring 307 to form an elastic support structure. When the occupant leans against it, the sponge backrest 311 is compressed. Through the linkage of the spring 307 and the fixed plate 305, a buffering effect is achieved, improving comfort. The protective soft edge 309 and the ventilation holes 308 further enhance the comfort and ventilation of the seat. The backrest reinforcement plate 310 adopts a lightweight hollow reinforcement structure, which reduces weight while ensuring strength, and improves the overall rigidity and durability of the seat, thereby completing a series of tasks.
