AI Technical Summary
During vibration, the damping springs of existing generators are prone to resonance with the generator, which increases the amplitude of the vibration and affects the buffering effect.
The buffer mechanism employs a buffer cylinder, piston, and buffer rod, combined with the design of an airbag and friction plate. By slowly moving the piston inside the buffer cylinder and deforming the airbag, the friction plate generates resistance to reduce the vibration amplitude.
It effectively reduces the vibration amplitude and impact force of the generator, improves the shock absorption effect, and avoids damage to the generator caused by repeated oscillations.
