Description

Technical Field

[0001] This utility model relates to the field of vehicle frame technology, and in particular to an integrated streamlined vehicle frame. Background Technology

[0002] The frame of an electric bicycle is a crucial component of the vehicle's structure. It not only supports the weight of the entire vehicle but also bears the rider and any potential loads. The design and construction of the frame significantly impact the performance, safety, and comfort of the electric bicycle. The frame provides a solid foundation for the electric bicycle, connecting all major components, including the battery, motor, front and rear wheels, seat, and handlebars. A well-designed frame effectively distributes the rider's weight and various forces generated during riding, such as acceleration, braking, and steering, ensuring vehicle stability and safety. One-piece streamlined electric bicycle frames, which reduce air resistance, are increasingly popular. They integrate the frame with components such as the fork and seatpost into a single unit, or embed cables and tubing within the frame, resulting in a more streamlined shape and reduced wind resistance. Furthermore, this design enhances the bicycle's aesthetics and can sometimes improve the rider's experience. However, in traditional one-piece streamlined frames, most tubing is completely enclosed within the frame, making cable replacement difficult. Utility Model Content

One end of the spring 82 is fixedly connected to the stop block 81 and the other end is fixedly connected to the limiting block 521.

[0050] When replacing brake cables or other hoses, detach both ends of the hose from the electric bicycle frame. Press the tail of the left clamping ring 511, causing it to rotate around the center post and move away from the right clamping ring 513. Release the clamp on the hose and pull the hose from above the connecting ring post 6, pulling it out of the guide groove 44. To replace the new hose, squeeze the handle 533 and pull it outward. The handle 533, through the connecting plate 531, moves the stop block 81 outward, compressing the spring 82. The connecting plate 531 moves away from the surface of the lower right frame rod 42, facilitating the movement of the locking part 5. Hold the handle 533 and move the locking part 5 near the connecting ring post 6. Release the handle 533, and the spring 82 rebounds, moving the connecting plate 531 towards the surface of the lower right frame rod 42 through the stop block 81, pressing the connecting plate 531 against the lower right frame rod 42. On the support rod 42, to prevent it from sliding along the guide groove 44, insert one end of the new pipeline into the guide groove 44 through the connecting ring post 6. Press the tail of the left clamping ring 511 to open the clamping part 51. Place one end of the new pipeline between the left clamping ring 511 and the right clamping ring 513. Release the left clamping ring 511. The torsion spring at the central post drives the left clamping ring 511 to rotate in the opposite direction, so that the left clamping ring 511 turns to the right clamping ring 513, clamping the new pipeline between the two. In the same way, move the snap-fit ​​part 5 along the guide groove 44 to the tail of the lower right support rod 42 to facilitate pulling out the new pipeline from the tail of the lower right support rod 42. Press the left clamping ring 511 again to pull out the new pipeline from the tail of the lower right support rod 42 and fix both ends of it to the electric bicycle to complete the pipeline replacement.
