Description

Technical Field

[0001] This utility model relates to the field of electric vehicle seat bucket technology, and in particular to a seat bucket structure and an electric vehicle. Background Technology

[0002] With the popularization of two-wheeled electric vehicles and the rapid development of lithium battery technology, lithium batteries have become the mainstream power source for two-wheeled electric vehicles due to their advantages such as high energy density and long cycle life. Currently, the battery compartments of two-wheeled electric vehicles on the market are mainly divided into two layouts: foot pedal compartments and seat bucket compartments. Due to size and shape limitations, lithium batteries usually cannot be fitted to the foot pedal mounting positions of traditional lead-acid batteries, requiring a seat bucket mounting solution.

[0003] In existing technologies, there are two main methods for securing lithium batteries in the seat compartment: one is to directly install a rubber pad on the seat base, using the elastic deformation of the rubber to compress and secure the battery; the other is to add a battery cover with a rubber pad to the seat base, connecting the cover to the base with screws, and using the rubber pad on the cover to secure and constrain the battery. While both methods ensure that the battery does not shift during vehicle operation, avoiding the risk of loose wiring or short circuits due to battery movement, both require a significant amount of space inside the seat compartment for installing the securing structure. This design drastically reduces the effective volume inside the seat compartment, preventing users from using this space to store other items, severely impacting the product's practicality and user experience.

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0023] like Figures 1-8 As shown, the seat bucket structure provided in this embodiment includes: a seat bucket body 100 and a battery cover assembly 200; a cavity is formed inside the seat bucket body 100, and the battery cover assembly 200 is rotatably connected to the seat bucket body 100. The battery cover assembly 200 is installed on the seat bucket body 100 by means of rotatable connection. When the battery cover assembly 200 is in the closed state, it divides the cavity into two independent functional areas: the lower part forms a battery compartment for installing the battery body 10; the upper part forms a storage compartment for storing the user's personal belongings or other accessories. This makes full use of the internal space of the seat bucket, realizes the integrated layout of battery and storage functions, and significantly improves the overall space utilization efficiency of the vehicle.

[0024] The inner wall of the battery compartment is provided with a limiting structure 110, which is used to abut against the side wall of the battery body 10 located in the battery compartment, thereby positioning and constraining the battery body 10 in the lateral direction. The battery cover assembly 200 is covered on the top of the battery body 10 located in the battery compartment to restrict the movement of the battery body 10 in the battery compartment, thereby positioning and constraining the battery body 10 in the vertical direction.

[0025] Specifically, the limiting structure 110 is configured as a limiting rib, and multiple limiting ribs are provided. All multiple limiting ribs abut against the outer side wall of the battery body 10 to prevent it from lateral displacement due to vibration or impact during vehicle operation.

[0026] In addition, the inner wall of the battery compartment is provided with a partition structure 120, which is used to divide the battery compartment into two battery installation spaces. Each battery installation space is used to install one battery body 10. Thus, the requirement for two battery capacities can be met by increasing the number of partition structures 120, thereby increasing the requirement for more battery bodies 10.

[0027] In an optional embodiment, the seat bucket structure further includes a rotating assembly 300; the rotating assembly 300 is disposed on the seat bucket body 100 and connected to the battery cover assembly 200, so that the battery cover assembly 200 can rotate relative to the seat bucket body 100 around the rotating assembly 300 to switch between an open position and a closed position. When the battery cover assembly 200 is in the closed position, the battery cover assembly 200 completely covers the upper opening of the battery compartment and is tightly fitted to the top of the battery body 10 located in the battery compartment, thus completing the encapsulation and fixation of the battery.

[0028] The rotating assembly 300 specifically includes a rotating shaft 310 and a rotating connector 320. The two ends of the rotating shaft 310 are rotatably connected to the main body 100 of the seat bucket, and the rotating shaft 310 serves as the rotation center axis. The rotating connector 320 is specifically configured as a rocker arm structure. One end of the rotating connector 320 is connected to the rotating shaft 310, and the other end is fixedly connected to the battery cover assembly 200, thereby transmitting the rotational motion to the battery cover assembly 200, so that the rotating connector 320 can be smoothly flipped open or closed. This structure has good mechanical stability and durability and is suitable for frequent use scenarios.

[0029] The rotating assembly 300 also includes a decorative element 330 and a trim panel mount 340; the trim panel mount 340 is fixedly connected to the seat body 100 and is located above the rotating shaft 310. The decorative element 330 is mounted on the side of the trim panel mount 340 away from the rotating shaft 310 and faces the exposed surface. The main function of the decorative element 330 is to cover the rotating shaft 310 and prevent exposed metal parts from affecting the overall aesthetic appearance.

[0030] To enhance the safety and reliability of the battery cover assembly 200 in the closed state, the bucket structure is also equipped with a locking component 400, which is integrated into the battery cover assembly 200. Correspondingly, the side wall of the bucket body 100 has a recessed slot 130. The locking component 400 has two working modes: locked and unlocked. When locked, a portion of the locking component 400 extends into the slot 130, forming a mechanical limit to prevent the battery cover assembly 200 from being accidentally opened. When it needs to be opened, the user can operate the locking component 400 to disengage from the slot 130, entering the unlocked state, thus allowing the battery cover assembly 200 to rotate and open normally.

[0031] The locking assembly 400 specifically includes a locking mounting plate 410, a locking pull ring 420, and a locking part 430. The locking mounting plate 410 is fixed to the internal structure of the battery cover assembly 200, serving as the basic support component of the entire locking mechanism. The locking pull ring 420 is rotatably connected to the locking mounting plate 410 via a hinge, with one end extending into the locking part 430. By manually pulling or actuating the locking pull ring 420, the locking part 430 can be rotated around a pivot point, thereby controlling its insertion into or disengagement from the latch 130, achieving the switching between locking and unlocking.

[0032] To further enhance the structural strength and wear resistance of the locking area, the locking assembly 400 also includes a locking reinforcement plate 440. This reinforcement plate is located at the opening of the bayonet 130, is typically made of metal, and is embedded or fixed in the plastic shell of the seat body 100. The locking reinforcement plate 440 not only withstands the mechanical stress caused by repeated insertion and removal of the locking part 430, but also prevents wear or deformation of the material around the bayonet 130 after long-term use, thus extending its service life.

[0033] The battery cover assembly 200 itself consists of a battery case cover 210 and a battery separator 220. The battery case cover 210 is located on the externally visible side, fixedly connected to the battery separator 220 and covering its surface. The battery separator 220 has an elastic part 221 on the side facing the battery compartment. The elastic part 221 is specifically configured as a rubber pad, which can make flexible contact with the top of the battery body 10 when the battery cover assembly 200 is closed, providing buffer pressure and avoiding damage to the battery casing by hard compression. In addition, the deformation capability can compensate for assembly tolerances, ensuring that batteries of different sizes or slightly different heights can be effectively pressed together, improving compatibility and sealing.

[0034] Furthermore, based on the above, the electric vehicle provided in this embodiment includes a frame, a first support 11, a second support 12, a third support 13, and a seat bucket structure; the top of the seat bucket body 100 extends outward to form an outer edge, one end of the outer edge of the seat bucket body 100 is connected to the first support 11, the other end of the outer edge is connected to the second support 12, and the bottom of the seat bucket body 100 is connected to the third support 13. The first support 11, the second support 12, and the third support 13 are all connected to the frame, and the three supports jointly bear the load of the seat bucket structure, firmly integrating it onto the vehicle frame to ensure structural rigidity and vibration stability during riding.

[0035] In summary, this seat bucket structure, through its ingenious spatial partitioning design, integrates the battery compartment and storage compartment into one unit, maximizing the use of limited space while ensuring stable battery installation. Combined with multiple technical measures such as the limiting structure 110, elastic clamping, rotational opening and closing, and locking protection, it solves the problems of insecure battery fixation and significant space waste in traditional seat buckets. It is particularly suitable for the field of light electric vehicles such as electric two-wheelers and electric scooters, and has high practical value and promising prospects for widespread adoption.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
