A cab protection structure in line with ergonomics

Abstract

The present invention discloses a cab protection structure that conforms to ergonomics, wherein the return motor stops driving upon receiving a collision signal, and the return spring drives the arc-shaped telescopic rod to extend out of the arc-shaped fixed rod, thereby driving the foot support plate and the adjusting screw to rotate, so that the foot support plate drives the driver's feet to retract, thereby keeping the driver's feet away from the collision position of the vehicle body; when a collision occurs, the vehicle body applies a thrust to the contact plate, and the abutment spring slows down the thrust transmitted from the contact plate to the protection plate, so that the protection plate is subjected to a smaller elastic force of the abutment spring, thereby reducing the collision force on the driver's feet at the moment of the vehicle collision, thereby preventing the driver's feet from being squeezed during the vehicle collision.
