Technical Field
The present invention relates to a passive safety device for a vehicle.
Background
Steel plate is a very common material, and when the steel plate is transported, the steel plate is usually stacked in a hopper of a loading vehicle and then tightened by a steel cable.
However, this loading method has a significant technical drawback that when the vehicle brakes, the inertia of the vehicle is very large due to the inertia of the vehicle and the dead weight of the steel plates, and the steel plates loaded in the hopper of the vehicle are very large when the vehicle brakes suddenly, and the steel plates are very smooth due to the plane contact between the two steel plates stacked on each other, which aggravates tragedy.
And after the steel plates are stacked, due to the mutual attachment, no reasonable force application point exists in the later stage during the unloading, and inconvenience is brought to the unloading.
Therefore, the passive safety device which can be assembled with a vehicle and is used for clamping the steel plate and preventing the steel plate from invading the vehicle in a cab is designed.
