With the development of the industry, users' requirements for products are also increasing. In addition to meeting basic driving needs, users have also put forward requirements for comfort, aesthetics and humanization.

[0003] As a crucial component of electric vehicles, the seat cushion not only directly impacts user comfort due to its contact with the user, but also serves as a sealed cover for the storage space underneath. Therefore, seat cushion design requires attention not only to comfort but also, and more importantly, to its sealing and safety.

[0004] Currently, most electric vehicle seat cushions are connected to the frame at one end via a hinge, while the other end is detachably connected to the frame via a locking hook. This allows the seat cushion to be flipped open around the hinge to reveal the storage space underneath. Traditional locking hooks are fixed to the seat cushion with screws or other fasteners. For example, CN214084570U discloses a frame structure and electric vehicle, which includes a locking hook. The locking hook includes a base and a locking tongue. The base is connected to the seat cushion, and the locking tongue is connected to the base. The locking tongue is a plate, and a locking hole is provided at the end of the locking tongue away from the base. The base has opposing first and second sidewalls. This installation method is not only time-consuming and labor-intensive, but the threaded part of the seat cushion is also prone to wear during use, leading to overall failure. In addition, the sealing performance of current electric vehicle seat cushions for the storage space underneath is generally poor. Summary of the Invention

Detailed Implementation

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] Example 1

[0025] refer to Figures 1-4An electric vehicle seat cushion includes a housing 1 and a locking hook 2. The housing 1 is a plastic casting. The locking hook 2 is embedded in the housing 1 and integrally formed with the housing 1. The housing 1 has an outer side and an inner side. One end of the inner side of the housing 1 has a first connecting position 1a. The locking hook 2 is located at the center of the first connecting position 1a. The first connecting position 1a is provided with a mounting part 11, and the mounting part 11 is provided on both sides of the locking hook 2. The mounting part 11 is provided with a locking hole 101 for installing a buffer A. The inner side of the housing 1 is also provided with a mounting groove 12. The mounting groove 12 is opened along the edge of the inner side of the housing 1 and is used to install a sealing element B.

[0026] In this embodiment, the locking hook 2 is integrally molded with the housing 1 using an embedded casting method, thus eliminating the need for additional screw fastening. This not only improves assembly efficiency and avoids the risk of thread failure but also reduces the weight of the seat cushion and lowers production costs. Furthermore, this embodiment features a mounting groove 12 along the inner edge of the housing 1, into which a seal B is inserted. When the seat cushion is closed, the seal B partially conforms to the frame, thereby improving the sealing of the storage space.

[0027] In this embodiment, specifically, the locking hook 2 is a U-shaped metal component; wherein, the two ends of the open side of the U-shaped structure are embedded in the housing 1. In practical applications, after the two ends of the open side of the locking hook 2 are embedded in the housing 1, a sealed chamber is formed, which can be engaged with the locking structure on the vehicle frame to achieve opening and closing.

[0028] In a preferred embodiment, the mounting groove 12 is provided with a plurality of narrowing portions 121; the plurality of narrowing portions 121 are arranged at intervals along the extending direction of the mounting groove 12. This embodiment does not limit the number of narrowing portions, as long as they are arranged at appropriate intervals. The function of the narrowing portions 121 is to reduce the difficulty of assembly. The portion of the mounting groove 12 other than the narrowing portions 121 is relatively wide, allowing for quick clamping of the seal B. Therefore, during installation, the operator only needs to press the seal B at the narrowing portion 121 into the mounting groove 12. Preferably, the mounting groove 12 is a V-shaped groove.

[0029] refer to Figure 3Specifically, the buffer component A is a rubber buffer pad; one end of the rubber buffer pad has a first wide body A1, and the other end has a second wide body A2; the diameters of the first wide body A1 and the second wide body A2 are both larger than the diameter of the locking hole 101. In practical applications, the first wide body A1 passes through the locking hole 101, and the lower end face of the second wide body A2 abuts against the locking hole 101. When the seat is closed, the upper end face of the second wide body A2 of the rubber buffer pad can partially contact the frame, thereby ensuring that the rubber buffer pad can be firmly locked in the locking hole 101 after installation, making it difficult to fall off, and also preventing installation difficulties due to excessive tightness. This design ensures both buffering effect and ease of installation and maintenance. In addition, the rubber material of the buffer pad is chosen not only because rubber has good elasticity and buffering performance, which can effectively reduce the impact force when the seat is closed and protect the frame from damage, but also because rubber material has certain wear resistance and corrosion resistance, which can extend the service life of the buffer component A.

[0030] refer to Figure 4 Specifically, the sealing element B is a rubber sealing strip; one end of the rubber sealing strip is a clip B1, and the other end is a flat head B2; the clip B1 is used to insert into the mounting groove 12 for fixation; the flat head B2 has a cavity extending along the length of the rubber sealing strip. In practical applications, after the clip B1 is inserted into the mounting groove 12, it can abut against the mounting groove 12, especially in the narrowing portion 121 of the mounting groove 12, ensuring that the rubber sealing strip will not fall off during normal use and maintains an effective seal. As for the flat head B2, its cavity design gives it a certain compression margin, and when the seat is closed, the flat head B2 has a tendency to recover, thereby improving the sealing effect.

[0031] Specifically, it also includes a hinged chain plate 3, with a second connection position 1b at one end of the inner side of the housing 1; the first connection position 1a and the second connection position 1b are respectively arranged at both ends of the housing 1; the hinged chain plate 3 is located at the center of the second connection position 1b. The hinged chain plate 3 includes a pin 31 fixed to the inner side of the housing 1 and a hinge pressure plate 32 rotatably connected to the pin 31; the hinge pressure plate 32 is provided with a through hole 321 fixed to the frame. When the seat is opened and closed, the seat flips around the pin 31. It should be noted that this embodiment does not limit the installation method of the hinged chain plate 3. Those skilled in the art who use industry-standard technical solutions to replace the structure of the seat and frame hinge should also be within the protection scope of this embodiment.

[0032] To improve the load-bearing capacity of the seat cushion, a support column 13 is provided on the inner side of the housing 1; the support column 13 is located between the first connecting position 1a and the second connecting position 1b. One end of the support column 13 is fixed to the inner side of the housing 1, and the other end extends to the frame portion, forming an effective support structure.

[0033] To improve the comfort of the seat cushion and enhance the user experience, the outer surface of the housing 1 is sequentially covered with a sponge layer and a leather layer (not shown in the figure).

[0034] The sponge layer offers excellent elasticity and shock absorption, effectively mitigating the bumps during riding and providing a softer feel. The leather layer not only boasts an attractive appearance, enhancing the overall quality of the seat, but also offers excellent wear resistance and water resistance, effectively extending the seat's lifespan and maintaining its cleanliness and hygiene. This design allows the electric scooter seat to provide comfort while also being practical and durable, further enhancing the user experience.

[0035] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
