[0004] 2. Pedal Mechanism: The pedal mechanism is usually made of lightweight and high-strength alloy material and is firmly connected to the main frame.

[0005] 3. Wheels and transmission structure: This includes wheels, axles, hubs, chains or drive shafts, etc. The wheels are mounted on the frame via axles and hubs, while the chain or drive shaft transmits power from the motor to the wheels, driving the vehicle.

[0006] 4. Battery mounting structure: Used to mount the battery of electric vehicles.

[0007] In scenarios such as shopping and food delivery, when users need to place items on the pedals, the pedal positions that are originally used to support the rider's feet are occupied, making it difficult for the rider to obtain a foot support point, maintain a natural and relaxed riding posture, and reduce riding comfort. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this utility model provides a lightweight, high-strength integrated frame electric bicycle, which solves the technical problem that when users need to place items on the pedals in scenarios such as shopping and food delivery, the pedal positions that were originally intended to support the rider's feet are occupied, making it difficult for the rider to obtain a foot support point, maintain a natural and relaxed riding posture, and reduce riding comfort.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A lightweight, high-strength integrated frame electric vehicle includes a scooter frame section. Both ends of the scooter frame section are equipped with expansion mechanisms to increase the scooter area. Each expansion mechanism includes a mounting block, a support shaft, and an expansion plate. The mounting block is located on the outside of the scooter frame section. The end of the support shaft is fixedly mounted on the outside of the mounting block. The expansion plate is rotatably connected to the outside of the support shaft. The scooter frame section has a fixing mechanism on one side corresponding to each expansion plate to fix its position. Each fixing mechanism includes a fixing block, a moving groove, a spring, a limiting block, and a pull plate. A limiting groove is formed on the outside of each expansion plate. The limiting block is slidably connected inside the limiting groove and used to limit the rotation of the expansion plate. The fixing block is located on the outside of the scooter frame section. The moving groove is formed on the side of the fixing block near the expansion plate. There are two springs, both fixedly connected inside the moving groove. The limiting block is slidably connected inside the moving groove. One end of the pull plate, passing through the fixing block and extending into the moving groove, is fixedly mounted on the outside of the limiting block.

[0011] Preferably, each end of the scooter frame section is provided with two screws, and each screw is threaded with a nut. The mounting block and the fixing block are slidably connected to the outside of the two screws respectively. The scooter frame section has a placement groove on one side corresponding to each screw. The screw is fixedly installed inside the placement groove, and the mounting block and the fixing block are snapped into the placement groove.

[0012] Preferably, a rubber pad is fixedly installed on the upper surface of each enlarged plate.

[0013] Preferably, each limiting groove has a limiting spring piece fixedly connected inside to restrict the movement of the limiting block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When the expansion plate is not needed, the connection between the limiting block and the limiting slot can be released by pulling the plate, allowing the expansion plate to be folded downwards for storage. This avoids the problem of the expansion plate occupying space, maintains the advantages of the vehicle's lightweight design, and improves the flexibility and adaptability of the expansion plate in different application scenarios. When in use, the expansion plate provides a foot support plane for the rider, so that the user can maintain a natural and relaxed riding posture, avoid affecting the rider's dynamic control of the vehicle's center of gravity, and at the same time ensure the user's riding safety and comfort.

[0016] 2. The mounting block and fixing block are installed on the scooter frame section by screws and nuts. Due to the detachable design, when the expansion plate is damaged, the connection between the nut and the screw is released, and then the mounting block and fixing block are pulled upward to release the connection between the two and the screw and the placement slot. At this time, the expansion plate is removed. The modular and detachable design avoids the user from replacing the entire scooter assembly, thereby reducing the difficulty of replacement.

[0025] This application provides a lightweight, high-strength integrated frame electric vehicle, which effectively solves the technical problem that in scenarios such as shopping and food delivery, when users need to place items on the pedals, the pedal positions that were originally used to support the rider's feet are occupied, making it difficult for the rider to obtain a foot support point, maintain a natural and relaxed riding posture, and reduce riding comfort. Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the technical solution in this application embodiment effectively solves the technical problem that in scenarios such as shopping and food delivery, when users need to place items on the pedals, the pedal positions originally used to support the rider's feet are occupied, resulting in the rider not being able to obtain a foot support point, making it difficult to maintain a natural and relaxed riding posture, and reducing riding comfort. The overall idea is as follows:

[0027] To address the problems existing in the prior art, this utility model provides a lightweight, high-strength integrated frame electric vehicle, including a scooter frame section 1. Both ends of the scooter frame section 1 are provided with expansion mechanisms to increase the scooter area. Each expansion mechanism includes a mounting block 2, a support shaft 3, and an expansion plate 4. The mounting block 2 is located on the outside of the scooter frame section 1, the end of the support shaft 3 is fixedly mounted on the outside of the mounting block 2, and the expansion plate 4 is rotatably connected to the outside of the support shaft 3. The scooter frame section 1 has a fixing mechanism on one side corresponding to each expansion plate 4 for fixing the position of the expansion plate 4. Each mechanism includes a fixed block 5, a movable groove 6, a spring 7, a limiting block 8, and a pull plate 9. The fixed block 5 is located on the outside of the scooter frame section 1. The movable groove 6 is located on the side of the fixed block 5 near the enlarged plate 4. There are two springs 7, both of which are fixedly connected inside the movable groove 6. The limiting block 8 is slidably connected inside the movable groove 6. One end of the pull plate 9, which passes through the fixed block 5 and extends into the movable groove 6, is fixedly installed on the outside of the limiting block 8. Each enlarged plate 4 has a limiting groove 10 on its outside. The limiting block 8 is slidably connected inside the limiting groove 10 and is used to limit the rotation of the enlarged plate 4.

[0028] Two screws 11 are provided at both ends of the scooter frame section 1. Each screw 11 is threaded with a nut 12. The mounting block 2 and the fixing block 5 are slidably connected to the outside of the two screws 11. The screws 11 provide mounting support for the mounting block 2 and the fixing block 5. The nuts 12 are used to tighten and fix the position of the mounting block 2 and the fixing block 5.

[0029] Each of the scooter frame sections 1 has a placement groove 13 on one side corresponding to each screw 11. The screw 11 is fixedly installed inside the placement groove 13. The mounting block 2 and the fixing block 5 are both snapped into the placement groove 13. The placement groove 13 can restrict the rotation of the mounting block 2 and the fixing block 5. At the same time, the nut 12 and the screw 11 are both located inside the placement groove 13.

[0030] Each enlarged plate 4 has a rubber pad 14 fixedly installed on its upper surface. The rubber pad 14 increases friction and prevents the items from sliding.

[0031] Each limiting groove 10 has a limiting spring 15 fixedly connected inside to restrict the movement of the limiting block 8. One end of the limiting spring 15 is fixedly connected inside the limiting groove 10, and the other end extends outward. When the limiting block 8 enters the limiting groove 10, the limiting spring 15 deforms and fits against the outside of the limiting block 8.

[0032] Expanding mechanism: Mounting block 2 serves as the mounting base for support shaft 3. One end of support shaft 3 is fixed to mounting block 2, and the other end is rotatably connected to expansion plate 4, which connects mounting block 2 and expansion plate 4. Expansion plate 4 is rotatably connected to the outside of support shaft 3. When unfolded, it can expand the pedal area, effectively increasing the usable area of ​​the pedal, making it convenient for riders to place larger items or provide a more comfortable place for their feet.

[0033] Fixed mechanism: The fixed block 5 supports the fixed mechanism components such as the moving groove 6 and the spring 7. The moving groove 6 provides installation space and sliding track for the spring 7 and the limiting block 8. When the limiting block 8 is pulled, the spring 7 stores elastic potential energy. When the pulling force is removed, the spring 7 releases the elastic potential energy to push the limiting block 8 to reset. The limiting block 8 restricts the rotation of the expanding plate 4 by cooperating with the upper limit groove 10 of the expanding plate 4, thereby locking the position of the expanding plate 4. The pull plate 9 allows the user to apply force to drive the limiting block 8 to slide in the moving groove 6, thereby releasing the connection between the limiting block 8 and the limiting groove 10.

[0034] Working principle:

[0035] The first step is that when the rider needs to increase the pedal area to place items or obtain a more comfortable foot space, the expansion plate 4 is fixed by the connection between the limiting block 8 and the limiting groove 10. At this time, the expansion plate 4 is parallel to the pedal, and the user can place both feet naturally on the expansion plate 4 or place excess items on the expansion plate 4.

[0036] The second step is to pull the pull plate 9 when the expansion plate 4 is not needed, so that the pull plate 9 moves the limiting block 8. During this process, the limiting block 8 gradually moves away from the limiting groove 10 on the expansion plate 4 until the connection between the two is completely released. At this time, the spring 7 is compressed, and the expansion plate 4 is no longer restricted by the limiting block 8. The user can rotate the expansion plate 4 downward so that it fits near the scooter frame section 1 to reduce space occupation. When the expansion plate 4 is rotated to the appropriate position, the user releases the pull plate 9. The spring 7 pushes the limiting block 8 to reset due to the release of elastic potential energy. The limiting block 8 is then re-fitted to the outside of the expansion plate 4 to prevent the expansion plate 4 from rotating accidentally during vehicle operation.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
