[0034] In the description of this application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance. In addition, in the description of this application, unless otherwise specified, "plurality" means two or more.

[0035] Figures 1-4 The seat cushion of this embodiment is a structural diagram. The seat cushion can be installed and connected to the seat tube or seat bucket of a vehicle to provide riding comfort. The vehicle can be an electric vehicle, a bicycle, a motorcycle, etc. The seat cushion includes a metal base plate 1, a plastic base plate 2 and a surface covering layer 3, such as Figure 4 The plastic base plate 2 surrounds and is connected to the outer side of the metal base plate 1 to form the basic frame of the seat cushion for supporting the seat cushion.

[0036] The metal base plate 1 can be a sheet metal component, made of metal materials such as aluminum or steel, and possesses sufficient strength and durability. The plastic base plate 2 and the metal base plate 1 serve as the foundational framework for the seat cushion, ensuring its sufficient strength and durability. Replacing part of the original plastic base plate with the metal base plate 1 reduces the plastic component ratio and improves flame retardancy.

[0037] The metal base plate 1 is integrally connected to the plastic base plate 2 through an injection molding process. The metal base plate 1 is pre-embedded in the mold for the plastic base plate 2. Then, when the molding material is injected to form the plastic base plate 2, the metal base plate 1 and the plastic base plate 2 are injection-molded into a single piece. This integrated injection molding process (also known as insert molding or overmolding) combines the strength of metal with the lightweight and easy-to-form properties of plastic, significantly improving structural strength and durability, simplifying the assembly process, increasing production efficiency, and reducing costs.

[0038] Injection holes 11 are provided on both sides of the metal base plate 1. Figure 3 and Figure 4 As shown. When the plastic base plate 2 and the metal base plate 1 are integrally injection-molded, the injection material passes through the injection holes 11 to enhance the bonding strength between the metal base plate 1 and the plastic base plate 2, ensuring a secure connection between the two. This also helps accurately position the metal base plate 1 in the injection mold. The injection holes 11 can be circular or polygonal to accommodate different injection molding processes and requirements. The number and location of the injection holes 11 can be customized.

[0039] In this embodiment, the plastic base plate 2 is injection molded and connected to the outer periphery of the metal base plate 1, so that the outer periphery of the metal base plate 1 is fixed within the plastic base plate 2, thereby improving the structural strength. At the same time, the plastic base plate 2 is injection molded and connected to the outer periphery of the metal base plate 1, which not only reduces the proportion of plastic parts but also retains the key structure that requires the use of the plastic base plate 2 to fix the surface covering layer 3. That is, the surface covering layer 3 covers the upper portion of the metal base plate 1 and the plastic base plate 2, and the surface covering layer 3 is connected to the plastic base plate 2. Optionally, to improve the aesthetics of the seat cushion, the surface covering layer 3 not only covers the upper surface of the plastic base plate 2, but also covers its sides and is curved to cover its bottom surface.

[0040] The surface covering layer 3 covers the top of the plastic bottom plate 2 and the metal bottom plate 1, and the surface covering layer 3 is connected to the plastic bottom plate 2, such as Figure 1 and Figure 2 As shown, the surface covering layer 3 and the plastic base plate 2 can be connected by adhesive bonding, suture stitching, Velcro fastening, and nailing. The surface covering layer 3 is intended to come into direct contact with the user and should be wear-resistant, non-slip, waterproof, and breathable. Materials such as synthetic leather and fabric can be used to ensure comfort while increasing friction, preventing slippage during riding and reducing discomfort during extended rides.

[0041] After the surface covering layer 3 is connected to the plastic bottom plate 2, a filling cavity 9 is formed between the surface covering layer 3 and the metal bottom plate 1 and the plastic bottom plate 2. Figure 3 As shown. The seat cushion also includes filler, which is filled in the filling cavity 9. The filler is used to increase the vehicle's riding comfort. Common filler materials include foam, gel, sponge, etc. Different fillers can provide different degrees of cushioning effect. Optionally, shock absorbers such as springs can be installed in the filling cavity 9 as needed to absorb vibration and impact during riding.

[0042] like Figure 4 As shown, the outer side of the plastic base plate 2 is provided with a mounting groove 21 for mounting a sealing strip to seal the filling cavity 9. The outer side of the plastic base plate 2 refers to the side facing away from the surface covering layer 3. The mounting groove 21 can be provided along the inner edge of the plastic base plate 2. Preferably, the mounting groove 21 can be annular.

[0043] Furthermore, the outer side surface of the plastic bottom plate 2 is further provided with a plurality of groups of first clamping blocks 4 and second clamping blocks 5, and the plurality of groups of first clamping blocks 4 and second clamping blocks 5 are arranged on the mounting groove 21 at intervals, such as Figure 4 As shown. Each set of first and second clamping blocks 4 and 5 is positioned relative to each other above the mounting groove 21, and is used to secure the sealing strip installed in the mounting groove 21 to prevent it from falling off. One end of the first and second clamping blocks 4 and 5 is respectively connected to the two sides of the top of the mounting groove 21, and the other end extends toward the interior of the mounting groove 21, forming a gap between the two that is smaller than the width of the mounting groove 21, facilitating the installation of the sealing strip.

[0044] Furthermore, a plurality of machining holes 22 are provided in the mounting groove 21, and the plurality of machining holes 22 correspond to the positions of the plurality of groups of first clamping blocks 4 and second clamping blocks 5. The arrangement of the machining holes 22 facilitates the formation of the first clamping blocks 4 and second clamping blocks 5 during injection molding of the plastic base plate 2.

[0045] like Figures 2-4 As shown, the seat cushion also includes embedded screws 6, riveted studs 7, and multiple compression rubbers 8. The embedded screws 6 are attached to one side of the plastic base plate 2 via injection molding, with the shank of the embedded screws 6 exposed. The riveted studs 7 are riveted to the side of the metal base plate 1 away from the embedded screws 6. In other words, the embedded screws 6 and riveted studs 7 are located on either side of the seat cushion, facilitating connection to the vehicle body.

[0046] In one implementation, the embedded screw 6 can be fixedly connected to a metal connecting piece with a locking ring, and the rivet stud 7 can be fixedly connected to one side of the hinge. Thus, the seat cushion can be hinged to the vehicle body through the hinge, and can be locked to the vehicle body through the locking ring. The connection part between the vehicle body and the seat cushion can be set in the form of a seat tube or a seat bucket. Taking the seat bucket as an example, one side of the hinge is fixedly connected to one side of the seat bucket, and the seat cushion is fixedly connected to the other side of the hinge through the rivet stud 7. The seat cushion can be rotated through the hinge to open or close the seat bucket. When closing the seat bucket, the seat cushion can be locked by connecting the locking ring of the metal connecting piece connected by the embedded screw 6 to the locking rod in the seat bucket. Preferably, there are two embedded screws 6 and two rivet studs 7 respectively, which are used to improve the stability of the connection.

[0047] Multiple compression rubbers 8 are distributed and fixed to the metal base plate 1. These provide excellent friction, increasing the friction between the seat cushion and the vehicle body, preventing the seat cushion from slipping during use and ensuring a safe and comfortable ride. They also provide protection, preventing wear and tear from direct contact between the seat cushion and the vehicle body, and extending the seat's service life.

[0048] In one implementation, the metal base plate 1 is stamped to have a plurality of connecting bosses 12 and reinforcing ribs 13. The number of connecting bosses 12 can be set as required, and the position can also be set as required. The connecting boss 12 is provided with a rivet hole 14 and a connecting hole 15. The rivet stud 7 is connected to the connecting boss 12 through the rivet hole 14, and the clamping rubber 8 is connected to the connecting boss 12 through the connecting hole 15. Among them, the connecting boss 12 where the rivet stud 7 is located is located on the side of the metal base plate 1 away from the embedded screw 6. The setting of the connecting boss 12 can meet the height requirements of the rivet stud 7 and the clamping rubber 8, and is convenient for connection or contact with other structures. The reinforcing rib 13 is used to strengthen the strength of the metal base plate 1. Optionally, an injection molding boss is provided on one side of the plastic base plate 2, and the embedded screw 6 extends from the injection molding boss. The injection molding boss facilitates the positioning of the hinge and the installation with the embedded screw 6.

[0049] The seat cushion of this embodiment uses part of plastic parts and part of metal parts as the support frame, which reduces the proportion of plastic parts in the entire vehicle, improves the flame retardant performance of the entire vehicle, and meets the requirements of the new national standard.

[0050] The embodiment of the application further provides a vehicle, which comprises a vehicle body and a seat cushion, and the seat cushion is consistent with the structure of the above-mentioned embodiment and will not be described again. The vehicle body is provided with a seat pipe or a seat barrel, and the seat cushion can be connected to the seat pipe or the seat barrel to provide comfort for riding. The seat cushion can be connected to the vehicle body through a pre-buried screw 6 and a riveted stud 7. The pre-buried screw 6 can be fixedly connected with a lock ring, and the riveted stud 7 can be fixedly connected with one side of a hinge. Thus, when the vehicle is in a stopped state, the seat cushion can be rotated to be folded or opened to the seat barrel through the hinge. The seat cushion can also be fixed in position through the lock ring to prevent the seat cushion from sliding during riding. The vehicle can be an electric vehicle, a bicycle, a motorcycle or the like.

[0051] The seat cushion of the vehicle in the embodiment uses part plastic parts and part metal parts as a support frame, reduces the proportion of plastic parts of the whole vehicle, improves the flame retardant performance of the whole vehicle, and meets the requirements of the new national standard.

[0052] The above only describes the preferred embodiments of the application and is not used to limit the application. The application can be variously modified and changed for those skilled in the art. Any modification, equivalent replacement, improvement and the like within the spirit and principle of the application shall be included in the protection scope of the application.
