Safe protection equipment for all vehicles and drivers from both front and rear
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 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.
1. A tube with spring or liquid cylinder comprising:
a tube ( 1 )
a part ( 6 ) fixing the tube to a chassis
single or multiple springs ( 2 ) or liquid cylinders ( 3 ) or combination of springs ( 2 ) and liquid cylinders ( 3 )
2 movable cylinders inside the tube with one in one end and another cylinder in other end of the tube for moving forth and back, one cylinder fixed to a bumper and another cylinder has a brake pad ( 4 ) on one end, both are hung to sliding rails fixed to the chassis, the sliding rails have a stopper to prevent the bumper move outside and another stopper to stop another cylinder if the brake pad ( 4 ) does not hit a tire ( 10 ) when a vehicle is turning left or right in big angle
characterized in that a colliding force hitting on the bumper moves the cylinder fixed to the bumper forward and push the spring ( 2 ) or liquid cylinder ( 3 ) that push another cylinder on another end moving towards the tire ( 10 ) until the brake pad ( 4 ) hits the tire then the spring ( 2 ) or liquid cylinder ( 3 ) will be compressed to reduce the colliding force that is passed to the tire hence significantly reduce the damage to a body of the vehicle and passengers inside the vehicle in that the colliding force hitting on the bumper is passed to the body of a vehicle without reduction in an airbag protection system.
2. The tube as claimed in claim 1 characterized in that the combination of springs ( 2 ) or liquid cylinders ( 3 ) has different values of elastic coefficient, with one having a low value of elastic coefficient, to reduce the colliding force smoothly with the spring or liquid cylinder of low value of elastic coefficient being compressed first and can reduce the injury to a person who is hit by the vehicle.
3. The tube as claimed in claim 1 characterized in that a tire ( 10 ) having elasticity will reduce the colliding force if the brake pad ( 4 ) hits the tire ( 10 ) when the vehicle is running in straight line or almost straight line.
4. The tube as claimed in claim 1 characterized in that it passes the reduced colliding force to the chassis of the vehicle through the stopper in the sliding rails when the vehicle turns left or right with big angle and the brake pad will not hit the tire.
5. The tube as claimed in claim 1 characterized in that the tube can be applied to one of a car, van and truck.
6. The tube as claimed in claim 1 characterized in that the tube can be applied to a front and/or rear of the vehicle.
