AI Technical Summary
Traditional spokes are prone to stress concentration when subjected to lateral impacts, radial torsional loads, or combined vibrations, leading to bending deformation and breakage, and resulting in a short service life.
The three-dimensional mesh support structure is formed by a first horizontal reinforcing plate, a second horizontal reinforcing plate, a first vertical reinforcing plate, and a second vertical reinforcing plate, combined with a first hardened protective layer, an elastic protective layer, and a second hardened protective layer to enhance the protective performance.
It improves the bending resistance and protective performance of the spokes, reducing the possibility of damage.
