AI Technical Summary
Existing high-thrust electric cylinders lack buffering capabilities, making the piston rod susceptible to damage due to the inertia of heavier objects.
An electric cylinder comprising an electric cylinder body and a buffer assembly is designed. The buffer assembly consists of a first fixed plate at the top of the piston rod, a limiting rod, a spring, a second fixed plate, a telescopic rod, and a spring, providing a dual buffering effect, and is equipped with front and rear protective shells to protect the electric cylinder body.
It effectively cushions heavier objects, protects the piston rod, extends the service life of the electric cylinder, and its detachable design facilitates repair and maintenance.
