Problems solved by technology

Due to the displacement of the shock absorber, the extension of the front wheel axle becomes smaller when the force is applied, and the riding safety decreases accordingly.

Embodiment Construction

[0017] A figure-eight bicycle frame includes an upper beam frame 1, a lower beam frame 5, a bridge qufu 2, a shock absorber 3, a shock absorber connecting seat 4, an upper beam frame and a lower beam frame The connecting shaft 6 has a front fork shoulder 8, two shock absorbers 11, two front fork legs 14, six connecting frames 9, two connecting seats 10, and six locking bolts 7. The connection method is formed by connecting each part with a specific angle between parts. The upper beam frame 1 and the lower beam frame 5 are connected by the connecting shaft 6 to realize the rotation of the lower beam frame 5, the lower beam frame 5 is connected with the shock absorber connecting seat 4, and the shock absorber 3 and the shock absorber connecting seat 4 are old The lock bolt 7 is connected, the shock absorber 4 is connected with the upper beam frame 1 with the lock bolt 7, the bridge Qufu 2 is connected with the upper beam frame 1 with the lock bolt 7, and the shock absorber conne...

Abstract

A figure-eight bicycle frame. The figure-eight frame is combined with a new type of front fork. The upper beam and the lower beam of the frame are connected by a shock absorber and a connecting shaft to form a figure-eight structure, so that the resistance direction of the shock-absorbing front fork due to force It is transferred to the forward and upward force of the front wheel. The deformation of the front and rear wheels changes, transforming the vertical upward damping force into a forward and upward resultant force consistent with the direction of motion, and the change in the connection angle structure presents a moving dynamic resultant force in the same direction as the frame and front fork structure changes. , Improve the riding stability and safety of the whole vehicle. The design is scientific and reasonable, easy to use, and the shock absorption effect is stable.

Description

technical field [0001] The invention belongs to bicycles, especially electric bicycles, in particular to a bicycle frame structure and a front fork structure. Background technique [0002] At present, the vehicle frame and the front fork of the bicycle, the main structure of the vehicle frame is a linear connection structure, and the structure of the vehicle frame realizes the strength requirement through the triangular structure. The front fork structure is compressed by the spring so that the displacement direction of the shock absorber moves linearly along the head tube of the front fork. To achieve the shock absorbing effect, the force direction of the shock absorbing front fork is transferred between 65 degrees and 75 degrees. When the whole vehicle is moving, the direction of the force acting on the front suspension fork is backward and upward. As a result, the damping loss caused by the force on the front suspension fork will slow down the movement speed of the whole...
