DETAILED DESCRIPTION

[0020] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are intended to illustrate the present invention but are not intended to limit the scope of the present invention. All other embodiments obtained by persons of ordinary skill in the art without creative effort are intended to fall within the scope of protection of the present invention.

[0021] Combine Figure 1、 Figure 2 、 Figure 3 and Figure 4 As shown, a car seat cushion support plastic structure includes a seat basin assembly 1, a seat basin support plastic part 3 is installed on the seat basin assembly 1, and a seat foam 2 is connected to the seat basin support plastic part 3. The seat basin support plastic part 3 is fixed to the seat basin assembly 1 by screws on the front and sides, and snap buckles 4 are symmetrically arranged on the outside of both sides of the seat basin support plastic part 3, and card slots 5 are arranged on the back of the rear ends of both sides of the seat basin support plastic part 3. Fixing steel wires 6 matching the card slots 5 are welded on both sides of the seat basin assembly 1.

[0022] The utility model proposes a car seat cushion support plastic structure, which provides stable support and convenient assembly method, ensuring the comfort experience of passengers and the durability of the seat. The seat basin assembly 1 serves as the basis of the entire seat support system. The seat basin assembly 1 is usually made of high-strength, lightweight materials, such as metal or reinforced plastic, to ensure sufficient structural strength and load-bearing capacity. The shape design conforms to ergonomic principles and aims to optimize sitting comfort and disperse pressure. The seat basin support plastic part 3 is a key intermediate connecting part, responsible for firmly supporting the seat foam 2 on the seat basin assembly 1. The seat basin support plastic part 3 adopts the injection molding process to ensure accurate size and a certain degree of elasticity to adapt to different manufacturing tolerances and assembly requirements. The seat foam 2 is the part that directly contacts the user and is usually composed of multiple layers of polyurethane foam of different densities to provide optimal riding comfort and support.

[0023] The seat support plastic 3 is directly connected to the seat pan assembly 1 via screws on the front and sides, ensuring a secure connection that remains stable even in extreme driving conditions. The selection and layout of the screws are meticulously calculated to balance tightening strength and assembly ease. To further enhance structural stability and facilitate quick assembly and disassembly, snap fasteners 4 are symmetrically positioned on either side of the seat support plastic 3. These allow the seat assembly to be initially positioned and secured without tools, simplifying the assembly process and facilitating future maintenance and replacement.

[0024] The rear end of the seat support plastic 3 is designed with slots 5, and matching them, fixed steel wires 6 are welded on both sides of the seat assembly 1. This not only increases the stability of the seat in the fore-aft direction, but also effectively prevents the seat from shaking during driving through the close fit between the steel wires and the slots 5, improving overall safety and durability.

[0025] This car seat cushion support plastic structure achieves a perfect combination of structural strength, assembly efficiency and riding comfort through ingenious design and material selection, and is an indispensable part of modern car interior design.

[0026] Combine Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the front of the seat basin support plastic part 3 is provided with several evenly distributed undercuts 31, and the seat foam 2 is provided with grooves 21 corresponding to the undercuts 31 one by one. The seat foam 2 is embedded with thin steel wires 22, which pass through the grooves 21 and are snap-connected with the undercuts 31.

[0027] Specifically, the front of the seat support plastic 3 features several evenly distributed undercuts 31, which not only strengthen the connection between the seat support plastic 3 and the seat foam 2 but also significantly enhance assembly precision and stability. Each undercut 31 is meticulously calculated and molded to ensure its precise positioning on the seat support plastic 3, while also providing sufficient strength and toughness to withstand the various mechanical challenges encountered during seat use.

[0028] The seat foam 2 features grooves 21 that correspond to the undercuts 31. The shape, size, and position of these grooves 21 perfectly match the undercuts 31, ensuring a seamless connection between the two during assembly. This design not only ensures ease of assembly, but also ensures a tight fit between the seat foam 2 and the seat support plastic 3 through precise dimensional control, effectively preventing loosening or deformation during long-term use.

[0029] To further strengthen this connection, fine steel wires 22 are embedded within the seat foam 2. These wires not only enhance the overall structural strength of the seat foam 2 but also serve as a connector. The wires 22 pass through grooves 21 in the seat foam 2 and form a snap-fit ​​connection with undercuts 31 on the seat support plastic 3. This not only increases the number of connection points but also, through the elasticity of the wires 22, provides a certain degree of cushioning and fault tolerance, allowing for more even stress distribution when the seat is under pressure, thereby extending its service life.

[0030] The snap-fit ​​connection between the thin steel wire 22 and the undercut 31 ensures quick and accurate positioning during assembly, while preventing damage or loosening due to improper assembly. In addition, this connection method facilitates disassembly and repair, greatly facilitating maintenance and upgrades of the seat.

[0031] Combine Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, face cover buckle strips 8 for fixing the face cover are provided on both sides of the basin support plastic part 3 , a plurality of holes 81 are provided on the front of the face cover buckle strips 8 , and a face cover fixing groove 82 is provided on the back of the face cover buckle strips 8 .

[0032] Furthermore, the seat basin support plastic 3 not only affects the seat's support and stability but also directly impacts its comfort and aesthetics. To further enhance the seat's overall quality, cover fastener strips 8 are specifically designed for securing the cover on either side of the seat basin support plastic 3. This not only simplifies the cover installation process but also ensures a tight fit between the cover and the seat structure, enhancing the seat's overall aesthetics and durability.

[0033] The front of the face cover buckle strip 8 is provided with several holes 81. These holes 81 not only provide the necessary connection points for the face cover, but also, through optimized number and placement, ensure even distribution and stable fixation of the face cover on the seat. The design of holes 81 fully considers the characteristics of the face cover material and the requirements of the assembly process, ensuring ease and accuracy during assembly.

[0034] The back of the face cover buckle strip 8 is provided with a face cover fixing groove 82. By closely fitting with the face cover material, a secure connection between the face cover and the seat structure is achieved. The shape, size, and depth of the face cover fixing groove 82 are precisely calculated to ensure a perfect match with the face cover material. During the assembly process, the face cover material is embedded in the face cover fixing groove 82 and is firmly fixed through friction or additional fixing parts (such as hooks, clips, etc.). This not only improves the fixing effect of the face cover, but also reduces the complexity and time cost of the assembly process.

[0035] Combine Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, Christmas tree buckles 7 for fixing the face cover are provided on both sides of the front end of the seat basin support plastic part 3.

[0036] Specifically, to further enhance the overall quality and ease of assembly, the seat's front end is equipped with two sides of the seat support plastic 3, known as "Christmas tree clips" 7 for securing the face cover. This "Christmas tree clip" 7 is a widely used connector in automotive interior assembly, named for its unique shape—resembling the bifurcated structure of a Christmas tree. It not only provides excellent securing effect but is also popular for its ease of installation and removal. On the seat support plastic 3, these clips are located on both sides of the front end, providing ideal connection points for securing the face cover.

[0037] The Christmas tree buckle 7 operates on a simple yet effective principle. Its main body is typically made of high-strength plastic or metal, offering a degree of elasticity and wear resistance. During assembly, the cover material is placed into the opening of the Christmas tree buckle 7. Then, by applying pressure or twisting, the forked portion of the buckle engages the cover material, securing it securely. This process is not only quick and easy, but also ensures the cover's stability and durability on the seat.

[0038] The Christmas tree buckle 7 is also very convenient to install and remove. When replacing the seat cover or repairing the seat, simply press or twist the buckle to easily remove or reinstall the cover. This not only improves assembly efficiency but also reduces maintenance costs, providing great convenience for the long-term use of car seats.

[0039] Combine Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the seat basin support plastic part 3 is an injection molded part with metal plates embedded on both sides of the rear end.

[0040] Furthermore, the seat basin support plastic part 3 adopts an advanced one-piece injection molding process, the most notable feature of which is that metal plates are embedded on both sides of its rear end. One-piece injection molding is a manufacturing process in which molten plastic is injected into a mold and then solidified by cooling to form the desired shape and size. It not only has high production efficiency, but also can produce plastic products with complex structures, precise dimensions and good surface quality. During the manufacturing process of the seat basin support plastic part 3, the plastic material is heated to a molten state and then injected into a pre-designed mold under high pressure. The structural design inside the mold accurately reflects the final shape and size of the seat basin support plastic part 3, including the reserved metal plate embedding positions on both sides of the front end.

[0041] The metal plates embedded on both sides of the rear end of the seat pan support plastic 3 not only provide additional strength and rigidity, but also enhance its resistance to shock and vibration. This composite material design enables the seat pan support plastic 3 to withstand greater loads while maintaining a small size and weight, thereby optimizing the overall performance of the seat.

[0042] The integrated connection between the metal sheet and the plastic is achieved through precise mold design and injection molding. During the injection molding process, the molten plastic tightly wraps around the metal sheet, forming a strong bond. This not only ensures a tight fit between the metal sheet and the plastic, but also avoids safety hazards caused by loosening or falling off during use.

[0043] Combine Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, mesh reinforcement ribs 32 are provided on both sides of the front end of the seat basin support plastic part 3, and a cross-shaped reinforcement rib 33 is provided on the front end of the seat basin support plastic part 3.

[0044] Furthermore, in the design of the seat basin support plastic part 3, mesh reinforcement ribs 32 are specially set on both sides of the front end, and an X-shaped reinforcement rib 33 is arranged in the central position of the front end. These design elements together constitute the core guarantee of the structural strength of the plastic part.

[0045] The design of the mesh reinforcement ribs 32 is inspired by natural grid structures, such as spider webs and honeycombs, which are known for their exceptional stability and load-bearing capacity. The mesh reinforcement ribs 32 not only increase the overall strength of the plastic component but also effectively disperse the stress and pressure generated during seat use through their lattice structure, thereby extending the service life of the plastic component.

[0046] Another common structural reinforcement design is the "X"-shaped rib 33, named for its resemblance to the English letter "J." In the seat support component 3, the "X"-shaped rib 33 is positioned centrally at the front end of the component, complementing the mesh-shaped rib 32 to form a dual reinforcement structure. The "X"-shaped rib 33 not only enhances the rigidity and stability of the component's front end, but also optimizes stress distribution through its unique shape, reducing fatigue damage over time.

[0047] Combine Figure 2 、 Figure 3 and Figure 4 As shown, the front end of the seat basin assembly 1 is provided with a support frame 9 extending outward.

[0048] Specifically, the design of the seat pan assembly 1 features an outward-extending support frame 9 at the front, which plays a crucial role in improving the overall performance of the seat. This outward extension effectively increases the support area and stability of the front end of the seat pan assembly 1. This not only improves the seat's load-bearing capacity when supporting passenger weight, but also enhances its stability in extreme driving conditions such as sudden braking and sharp turns, providing passengers with a safer and more reliable riding environment.

[0049] Combine Figure 1 and Figure 2 As shown, the seat basin assembly 1, the fixing wire 6 and the support frame 9 are all made of metal.

[0050] Specifically, the seat basin assembly 1, the fixing steel wire 6 and the support frame 9 are all made of metal. This choice is not only based on the physical properties of the material itself, but also fully considers the load-bearing capacity, stability, durability of the seat and the safety of the passengers.

[0051] The seat pan assembly 1, as the main supporting structure of the seat, is crucially designed for its metal material. Metal offers high strength, high rigidity, and excellent fatigue resistance, allowing it to withstand the various forces and vibrations generated during use, ensuring the stability and safety of the seat structure. Furthermore, metal exhibits excellent thermal conductivity, which helps dissipate heat from within the seat and enhance passenger comfort. During manufacturing, the seat pan assembly 1 is typically constructed of high-quality steel or aluminum alloy, undergoing precision stamping, welding, and surface treatment to ensure its precise shape and dimensions, smooth surface, and the desired strength and aesthetics.

[0052] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
