AI Technical Summary
Existing rigid mechanical impact safety devices lack effective anti-collision structures when sensors malfunction or misdetect, resulting in a lack of buffering during mechanical impacts and posing safety hazards.
A safety device was designed, comprising a slide bar, a sleeve, a damping telescopic rod, a buffer plate, a buffer linkage, a spring, and a trigger switch. The device triggers braking by contacting the impacting object with the contact plate, and absorbs the impact force using the spring and buffer mechanism to avoid hard mechanical impacts.
When the sensor fails, the brakes are effectively triggered, and the impact force is buffered by springs and a buffer mechanism to avoid direct hard collisions and improve safety.
