A hood bumper for a vehicle having a hood including: a housing having a wall, a base, an internal chamber, and an opening to the internal chamber. The wall having an interior surface and an exterior surface. the interior surface defines the internal chamber. The hood bumper further including a biasing mechanism operably connected to the housing and a plunger operably connected to the biasing mechanism and configured to receive an exerted force from the hood. The hood bumper further including a bumper head operably connected to the housing and a support frame operably connecting the bumper head to the housing. The plunger is configured to first move into the bumper head to absorb an impact force to the hood, next the bumper head compresses to further absorb the impact force, and then the support frame collapses to even further absorb the impact force.

Safe protection equipment for all vehicles will significantly reduce the collision force by spring or liquid cylinder when the vehicle bumps to obstacle or two vehicles collide with each other. This equipment can be used on both front and rear of the vehicle. Combination of springs or liquid cylinder with different elasticity can reduce the collision smoothly. This equipment will protect both vehicles and drivers without changing the current air-bag protection system. It will significantly reduce the damage for serious collision accidents. This equipment is attached to the vehicle chassis on bottom, which will bear the collision force reduced by the spring or liquid cylinder. It might require some design change in vehicle chassis. One option is to add a pad to pass the reduced collision force to the elastic tire when colliding vehicles are running in straight line.

A vehicle includes a body structure, a push bar, and a damper connecting the push bar to the body structure. The damper includes a base and a rod that are movable relative to each other. The rod is attached to one of the push bar and the body structure, and the base is attached to the other of the push bar and the body structure. The damper is controllable to adjust a damping ratio of the damper and/or adjust a resting position of the rod relative to the base to axially move the push bar.

A dock bumper is provided. The dock bumper includes a housing holding a plurality of rollers arranged in an array. The plurality of rollers are arranged to absorb impact from a reversing vehicle. Upon impact, outer surfaces of the rollers are arranged to rotate relative to the frame. Consequently, scrubbing between the vehicle and dock bumper is reduced as are excess forces acting on fixings between the frame and wall. Also, a surface area at each contact location is increased as a cushioning effect is provided by rotation of the roller, thereby prolonging the operation life of the rollers. Furthermore, in one form, the dock bumper is modularized so that only worn or damaged rollers need be replaced at one time.

This equipment will protect both vehicles and drivers without changing the current air-bag protection system. It will significantly reduce the damage for serious collision accidents. This equipment is attached to the vehicle chassis with a pair of pad to pass the reduced collision force to the elastic tire when colliding vehicles are running in straight line. Normally vehicle running in straight line has high speed and the collision force is strong. The elastic tire can reduce the collision force further.

A vehicle is provided. The vehicle may include at least one crush can, a controller and a pump. The crush can may include front and rear chambers. The controller may receive a first signal indicative of a loading condition generated at the time of an impact, and the pump may displace a nano-porous liquid in response to a second signal from the controller into at least one of the front and rear chambers of the crush can.
