AI Technical Summary
Technical Problem
The limited elastic deformation of the center tube in existing bicycle frames results in a poor riding experience.
Method used
It adopts a split-type forward-tilting support structure for the central tube, with the forward-tilting branch tube of the central tube connected to the lower tube. Combined with the sheet support plate, it forms an equilateral triangle and a gradually changing cross section, which reduces the vertical stiffness of the central tube and maintains the horizontal stiffness. It is made of aluminum tube.
Benefits of technology
It increases rider comfort by reducing the vertical and horizontal stiffness of the center tube, thus improving the riding experience.

Abstract
A split type middle tube front leaning support frame, including head tube, upper tube, middle tube, lower tube, vertical fork and flat fork, the upper end of the upper tube and the lower tube is connected to the head tube, the middle tube extends downward from the end of the upper tube and is connected with the middle tube front leaning support pipe, the bottom end of the middle tube front leaning support pipe is connected to the lower tube, the lower end of the lower tube is connected with the flat fork through the five-way connection, the front end of the vertical fork is connected in front of the lower end of the middle tube, and an integral sheet-shaped support plate is arranged below the overlapping position of the lower end of the middle tube and the vertical fork, and the ends of the vertical fork and the flat fork are connected. The middle tube front leaning support pipe designed in the utility model effectively reduces the vertical stiffness of the middle tube, basically maintains or slightly reduces the horizontal stiffness of the bicycle, so that the comfort of the rider is increased.
