Abstract

The invention discloses a high-strength wheelchair front fork suspension structure and a working method. The high-strength wheelchair front fork suspension structure comprises two front fork frames which are symmetrically arranged, and the two front fork frames are connected through a connecting plate at the upper end. Two sets of hinge lugs are symmetrically arranged on the two sides of the connecting plate, and the hinge lugs are arranged above the front fork frames. Rocker arms are arranged at the lower ends of the front fork frames, the lower ends of the front fork frames are hinged to themiddle parts of the rocker arms, and a wheel shaft is arranged between the middle parts of the rocker arms. Dampers are symmetrically arranged on the two sides of each front fork frame, the upper ends of the dampers are hinged to the ends of the hinge lugs, and the lower ends of the dampers are hinged to the ends of the rocker arms. A wheelchair can be damped when running on a rugged road, so that the safety of a user is protected; and the hardness of springs can be adjusted, so that the damping capacity is adjusted, and the use requirements of different users can be met.

Description

technical field [0001] The invention belongs to the technical field of wheelchairs, and in particular relates to a high-strength wheelchair front fork shock-absorbing structure and a working method. Background technique [0002] Wheelchairs are an important tool for rehabilitation. They are not only a means of transportation for the physically disabled, but also a tool for them to use wheelchairs for physical exercise and participation in social activities. At present, there are many types of wheelchairs used by disabled people or frail old people, but most of them are unreasonable in structure or have poor shock absorption effect, which makes wheelchairs easily cause violent vibrations when driving on rough roads. At the same time, the shock absorption capacity cannot be adjusted freely, and cannot meet the needs of driving on different roads or different people. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to provide a hig...
