[0039] Figure 1 and Figure 2 These are schematic diagrams of the seat cushion from different perspectives in this embodiment. Figure 3 This is a partial sectional view of the seat cushion. (For example...) Figures 1-3 As shown, the seat cushion includes a metal base plate 1, a filling layer 2, an outer skin 3, and a pressure plate 4. The filling layer 2 is disposed on the outer surface 11 of the metal base plate 1 (i.e., the outer side of the metal base plate 1), and the outer skin 3 covers the filling layer 2 and at least a portion of the inner surface 12 of the metal base plate 1. The pressure plate 4 is then attached to the inner surface 12 of the metal base plate 1, thereby covering a portion of the outer skin 3. The outer skin 3 is thus clamped between the pressure plate 4 and the metal base plate 1. The pressure plate 4 and the metal base plate 1 cooperate to press and fix the outer skin 3, ensuring that the outer skin 3, the filling layer 2, and the metal base plate 1 are firmly assembled to form the seat cushion, preventing them from separating or falling off during use.

[0040] The metal base plate 1 provides the necessary rigidity and structural stability for the entire seat, directly bearing the weight of the rider and passengers as well as dynamic impacts (such as bumps and jumps) during riding, ensuring stability and comfort. Simultaneously, the seat connects to the electric bicycle frame via the metal base plate 1, completing the installation of the seat and frame. The metal base plate 1 seals the bottom of the seat, preventing dust, small stones, rainwater, etc., from entering the seat interior from below, protecting the internal filling layer 2 and other structures, and extending the seat's lifespan.

[0041] like Figure 5 and Figure 6As shown, the metal base plate 1 has an outer surface 11 and an inner surface 12, and the inner surface 12 of the metal base plate 1 is provided with a plurality of hooks 13. For example... Figure 1 and Figure 3 As shown, the outer skin 3 has multiple hanging holes 31. Figure 1 As shown, multiple hooks 13 are connected to multiple hanging holes 31 in a one-to-one correspondence, thereby realizing the pre-installation and positioning of the outer skin 3 and the metal base plate 1.

[0042] In this embodiment, the metal base plate 1 is configured as an inverted bowl-shaped or dome-shaped structure. For example... Figure 5 As shown, the inner surface 12 includes an inner top surface 121 and an annular inner side surface 122, the annular inner side surface 122 surrounding the inner top surface 121. Figure 1 and Figure 3 As shown, after the outer skin 3 covers the filling layer 2, it bends inward toward the metal base plate 1 to cover the annular inner side 122, and then extends to cover the inner top surface 121 of the portion, as shown. Figure 4 As shown. Here, "covering" refers to the outer skin 3 being in complete contact with the surface of the corresponding structure, encasing it within it.

[0043] In other embodiments, the outer skin 3 can also completely cover the inner surface 12 of the metal base plate 1, that is, the outer skin 3 covers the annular inner side 122 and the inner top surface 121. When the pressure plate 4 is located outside the outer skin 3 and connected to the inner top surface 121 of the metal base plate 1, it increases the area of ​​the outer skin 3 clamped between the pressure plate 4 and the metal base plate 1, further pressing the outer skin 3.

[0044] like Figure 5 and Figure 6 As shown, multiple hooks 13 are disposed on the annular inner side surface 122 of the metal base plate 1. After the outer skin 3 is covered with the filling layer 2, it can be bent inwards towards the metal base plate 1, and then the multiple hanging holes 31 of the outer skin 3 are pre-hung on the multiple hooks 13 of the metal base plate 1, thereby pre-fixing the relative positions of the outer skin 3, the filling layer 2, and the metal base plate 1. Preferably, the multiple hooks 13 are located on the annular inner side surface 122 near the inner top surface 121, and are arranged sequentially at equal intervals to improve the stability of the connection.

[0045] In this embodiment, the hook 13 can be formed by stamping from the outside to the inside of the side wall of the metal base plate 1. The hook 13 can be integrally formed by the metal base plate 1 during the overall stamping process, which reduces costs, lightens weight, increases strength, and simplifies production. In addition, the hook 13 can also be fixed to the metal base plate 1 by means of bonding, threaded connection, welding, etc.

[0046] The filling layer 2 is typically made of high-resilience, aging-resistant polyurethane (PU) foam to provide a comfortable seating experience and cushioning. The filling layer 2 can be fixed to the outer surface 11 of the metal base plate 1 by adhesive bonding, snap-fitting, or in-mold foaming to prevent displacement during use. The inner surface of the filling layer 2 perfectly matches the shape of the outer surface 11, increasing the contact area between the occupants and the filling layer 2, thus improving seating comfort.

[0047] The outer skin 3 is the part that passengers come into direct contact with, forming the overall structure and appearance of the seat cushion. It provides riding comfort and protects the internal structure of the seat cushion. The material of the outer skin 3 can be artificial leather, genuine leather, polymer synthetic materials, etc.

[0048] like Figure 1 and Figure 3 As shown, the pressure plate 4 is connected to the inner surface 12 of the metal base plate 1, and at least a portion of the pressure plate 4 covers at least a portion of the outer skin 3. Thus, the connection and cooperation between the pressure plate 4 and the metal base plate 1 can press the outer skin 3 tightly. Figure 4 As shown, the inner top surface 121 of the outer skin 3 is covered by the pressure plate 4 after it is connected to the metal base plate 1, and the outer part of the pressure plate 4 is pressed onto the outer skin 3 located on the inner top surface 121.

[0049] In other embodiments, when the area of ​​the outer skin 3 covering the inner top surface 121 is greater than the area of ​​the pressure plate 4 or covers the entire inner top surface 121, after the pressure plate 4 is connected to the metal base plate 1, the pressure plate 4 can be pressed entirely on top of the outer skin 3, thereby improving the stability of fixing the outer skin 3.

[0050] The pressure plate 4 and the metal base plate 1 can be detachably connected by bolts, which facilitates processing and assembly. Multiple bolts can be evenly distributed circumferentially to improve the stability of the connection of the pressure plate 4 and the clamping force applied to the outer skin.

[0051] In this embodiment, the pressure plate 4 is a ring structure, such as... Figure 7 As shown. The outer edge shape of the pressure plate 4 is adapted to the shape of the inner top surface 121. After the pressure plate 4 is connected to the inner top surface 121, the outer skin 3 can be fixed in the circumferential direction. In addition, the outer edge of the pressure plate 4 is bent upward to form a bowl-shaped structure, and the side wall can simultaneously press the outer skin 3 in the circumferential direction, further fixing the outer skin 3.

[0052] like Figure 7 As shown, the pressure plate 4 is provided with multiple clearance grooves 41. The positions of the multiple clearance grooves 41 correspond one-to-one with the positions of the multiple hooks 13, which can prevent the hooks 13 from interfering with the pressure plate 4.

[0053] like Figure 7 and Figure 9As shown, the pressure plate 4 has an annular mounting groove 42, and a sealing strip 5 is installed inside the annular mounting groove 42. When the seat cushion is closed, the sealing strip 5 is used to ensure the seal between the seat cushion and the seat bucket, improving the waterproof performance between the two. Therefore, the shape of the annular mounting groove 42 is the same as the shape of the top surface of the seat bucket, thereby ensuring waterproof performance.

[0054] like Figure 8 and Figure 9 As shown, the top of the annular mounting groove 42 is provided with multiple sets of hooks 43 at intervals, and each set of hooks 43 extends from both sides of the top of the annular mounting groove 42 toward the middle. Figure 9 As shown, the sealing strip 5 includes a sealing body 51 and two snap-fit ​​strips 52. When the sealing strip 5 is connected to the pressure plate 4, the two snap-fit ​​strips 52 are limited and connected in the annular mounting groove 42 by multiple sets of hooks 43. The sealing body 51 is located outside the annular mounting groove 42, which can prevent the sealing strip 5 from falling off and separating from the pressure plate 4. The seat cushion and seat bucket achieve sealing by compressing the sealing body 51.

[0055] In other implementations, multiple sets of hooks 43 are replaced with hooks that extend along the entire top of the annular mounting groove 42, which can further enable the snap-fit ​​of the sealing strip 5.

[0056] like Figure 1 As shown, hinge 6 and locking member 7 are respectively installed on both sides of the metal base plate 1. The hinge 6 is used to connect with the seat bucket, thereby enabling the seat cushion and seat bucket to be hinged together. The locking member 7 is used to cooperate with the lock body on the seat bucket to lock the seat cushion and seat bucket. Therefore, the positions of the hinge 6 and locking member 7 on the metal base plate 1 are respectively opposite to the hinge position and the lock body position on the seat bucket.

[0057] like Figure 5 and Figure 6 As shown, a first mounting platform 14 and a second mounting platform 15 are provided on both sides of the metal base plate 1. The hinge 6 is mounted on the first mounting platform 14, and the locking member 7 is mounted on the second mounting platform 15. The first mounting platform 14 and the second mounting platform 15 can meet the requirements of the mounting height and position of the hinge 6 and the locking member 7.

[0058] In this embodiment, the pressure plate 4 is a ring structure, and the inner top surface 121 of the metal base plate 1 is exposed through the hollow part in the middle of the pressure plate 4. The hinge 6 and the locking member 7 are connected to the metal base plate 1 and are located in the hollow part in the middle of the pressure plate 4.

[0059] In one implementation, the hinge 6 is a hinge, and the locking element 7 is a locking hook. The hinge 6 and the locking element 7 can be fixed to the metal base plate 1 by means of bolts or welding, respectively. Preferably, the hinge 6 and the locking element 7 are made of metal, which can further reduce the proportion of plastic and improve fire safety performance.

[0060] like Figure 5 and Figure 6 As shown, the metal base plate 1 has multiple bosses 16. These bosses 16 are located inside the annular mounting groove 42, and each boss 16 is fitted with a buffer pad 8. The buffer pad 8 can be fixed by adhesive, snap-fit, or other methods. When the seat cushion and seat bucket are closed, the buffer pad 8 can first contact the object inside the seat bucket, providing a cushioning effect against deformation of the seat cushion. The buffer pad 8 can be a rubber pad, etc.

[0061] Furthermore, the metal base plate 1 is provided with reinforcing ribs 9, such as... Figure 5 As shown. The reinforcing rib 9 provides structural support for the metal base plate 1 and prevents deformation. The reinforcing rib 9 connects the boss 16, the first mounting platform 14, and the second mounting platform 15, thus connecting the various structural components and further increasing strength. The reinforcing rib 9 can be in a mesh-like or similar configuration.

[0062] In other embodiments, when the pressure plate 4 is a non-annular structure, the hinge 6, locking member 7, and buffer pad 8 can also be fixed on the pressure plate 4.

[0063] Preferably, the pressure plate 4 is made of metal, which further reduces the proportion of plastic and improves fire resistance.

[0064] In addition, a spring can be installed between the metal base plate 1 and the filling layer 2 to further improve the riding comfort of the rider.

[0065] The assembly process of the seat cushion in this embodiment is as follows: First, the filling layer 2 is formed on the outer surface 11 of the metal base plate 1; then, the outer skin 3 is wrapped around the outside of the filling layer 2, and the outer skin 3 is bent and extended toward the inner surface 12 of the metal base plate 1. The hanging holes 31 on the outer skin 3 are hung on the hooks 13 of the metal base plate 1 to achieve pre-installation; then, the pressure plate 4 is connected to the inner top surface 121 of the metal base plate 1 by bolts to press the outer skin 3; then, the sealing strip 5 is installed in the annular mounting groove 42 of the pressure plate 4, and the hinge 6, locking 7, and buffer pad 8 are respectively installed on the metal base plate 1.

[0066] This application embodiment also provides a vehicle, which includes a vehicle body and the aforementioned seat cushion, the seat cushion being mounted on the vehicle body. Optionally, the vehicle body is provided with a seat bucket, which can be used to store batteries or personal items. One end of the seat cushion is hinged to the seat bucket via a hinge member 6, thereby enabling the seat cushion and seat bucket to open and close. The other end of the seat cushion can be locked to the seat bucket via a locking member, serving as an anti-theft measure.

[0067] In this embodiment, the seat cushion replaces the base material with metal, reducing the amount of plastic used in the vehicle and improving its fire safety performance. At the same time, the metal base plate also ensures the seat cushion's functionality and manufacturability.

[0068] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
