AI Technical Summary
The use of nylon composite materials in the sliding components of existing car seat shock absorbers leads to hard wear of the rollers, resulting in a short service life. Furthermore, the sliding friction between a single bearing and the frame causes unstable movement.
The design includes a shock-absorbing upper frame, a shock-absorbing lower frame, a central scissor-type shock-absorbing assembly, and a rotating support assembly. Roller bearings are used to provide rolling friction, reduce sliding friction contact, and improve motion stability.
It extends the lifespan of the seat casters, improves the smoothness of movement, and reduces friction and wear.
