Safe protection equipment for all vehicles and drivers from both front and rear

Abstract

This equipment can be attached to the vehicle chassis with different ways based on the type of the vehicle. The chassis and the frame may need some enhancement.

1 . A hydraulic cylinder ( 1 ) comprising:
 a piston rod ( 2 ) that is fixed to the bumper on one end and to the piston on another end   a part such as screw rod ( 13 ) fixing the tube to the chassis   a spring ( 11 ) that retracts the piston when the force on bumper is removed   a check valve ( 3 ) that is opened when the fluid pressure hit high threshold and closed when the fluid pressure goes down to low threshold   other parts can be found in single-acting hydraulic cylinder in generic mechanical design   characterized in that the piston rod fixed to the bump push the piston ( 12 ) that push the liquid in the bottom chamber and the liquid will be compressed to absorb the colliding forces.   
     
     
         2 . The hydraulic cylinder as claimed in  claim 1  characterized in that the check valve will be opened and the fluid will flow out of the bottom chamber when the fluid pressure hit high threshold and the check valve will be closed and the fluid will be compressed again when the fluid pressure goes down to low threshold thereof the strong colliding force will be absorbed smoothly in several processes. 
     
     
         3 . The hydraulic cylinder as claimed in  claim 1  characterized in that it transfers the reduced colliding force to the chassis of the vehicle through parts ( 8 ) and parts ( 13 ). 
     
     
         4 . The hydraulic cylinder as claimed in  claim 1  characterized in that it can be applied to any type of vehicle such as car, van, truck and train 
     
     
         5 . The hydraulic cylinder as claimed in  claim 1  characterized in that it can be applied to front and/or rear of the vehicle. 
     
     
         6 . A spring or multiple springs ( 9 ) comprising:
 A spring ( 9 ) fixed to the bumper ( 6 ) on one end and to a bar ( 7 ) on another end   characterized in that the bumper pushes the spring thereof the spring is compressed to absorb the colliding forces.   
     
     
         7 . A combination of multiple springs as claimed in  claim 6  characterized in that the combination of springs with different elasticity will reduce the colliding force smoothly with the spring of soft elasticity being compressed first. 
     
     
         8 . The spring or combination of springs as claimed in  claim 6  characterized in that it transfers the reduced colliding force to the chassis of the vehicle through parts ( 7 ) and parts ( 8 ). 
     
     
         9 . The spring or combination of springs as claimed in  claim 6  characterized in that it can be applied to any type of vehicle such as car, van, truck and train 
     
     
         10 . The spring or combination of springs as claimed in  claim 6  characterized in that it can be applied to front and/or rear of the vehicle. 
     
     
         11 . A sliding rail or multiple sliding rails ( 10 ) comprising:
 1 or 2 or 4 sliding rails that are fixed to the bumper on one end and pass through holes in a bar on another end. The sliding rail can be a tube or a small bar.   a stopper ( 5 ) that can be a combination of tubes or a small plate on end of sliding rails ( 10 )   characterized in that the bumper will push the sliding rails moving forward along the hole in the bar and the stopper ( 5 ) will prevent the bumper move toward the front or rear direction.   
     
     
         12 . The sliding rails as claimed in  claim 11  characterized in that it can be applied to any type of vehicle such as car, van, truck and train. 
     
     
         13 . The sliding rails as claimed in  claim 11  characterized in that it can be applied to front and/or rear of the vehicle.
