Abstract

[Use of item]; This designed item is a frame that can be used for folding bicycles, ordinary bicycles, electric bicycles, electric vehicles, electric assist bicycles, etc. ;[Design Description];Please refer to each picture, the main design considerations are as follows: 1. The front fork is mainly smooth and rounded streamlines; 2. The body and rear fork are mainly based on strong contour streamline curves; 3. . The body is based on the central axis. The lower part begins to gradually gradually change forward and approaches the head tube, and then is cut off by a rounded tangent line. The upper and lower rounded corners of the front fork are cut off by a tangent line and gently gradient from top to bottom to the color separation line, which is in line with the color separation line of the front part of the body. Echo; 4. The body of the body is based on the central axis, and the lower part starts to smoothly gradient backwards at the corner of the rear part until the color separation disappears at the tail. The rear fork takes the central axis as the starting point, and the color separation line runs along the surface to the middle of the rear fork, and then the corner and the outline of the rear fork Parallel, the formed corner echoes the corner of the rear part of the body, and then the rear fork color separation line begins to smoothly gradient at the corner of the outline and disappears at the next corner, and the rear fork color separation line echoes the gradient color separation line at the rear of the body. The color separation lines of the front and rear forks echo the color separation lines of the body, and change from gradual to disappearing, making the front and rear forks and the body visually integrated, enhancing the overall visual and avant-garde silhouette of the vehicle. In addition, the appearance outline is also included in the scope of this design protection.
