1results about How to "Reduce collision energy" patented technology

This utility model provides a buffer device for elevator car overshooting, relating to the field of elevator safety technology. The buffer device includes a base plate, an energy-absorbing plate, a safety airbag, and a hydraulic buffer. The base plate is fixed to the top of the shaft. The hydraulic buffer is fixedly connected to the bottom surface of the base plate. The energy-absorbing plate is positioned below the hydraulic buffer and is slidably connected to the base plate, allowing it to rise and fall relative to the base plate. The safety airbag is fixedly connected to the bottom surface of the energy-absorbing plate. When an elevator car overshoots, the car first collides with the safety airbag. If the impact force exceeds a preset threshold, the airbag inflates within a short time to absorb the collision energy. The energy-absorbing plate continues to absorb the remaining energy, and the hydraulic buffer further reduces the collision energy. This buffer device significantly reduces the collision energy during an elevator car overshoot, minimizing harm to passengers and cargo inside the elevator car and improving elevator safety.
