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

Abstract

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.

Claims

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.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 provides the primary horizontal view from the left side of the vehicle. There are no other views since the equipment is simply composed of tubes or bars while the size needs further experiment based on the size and type of vehicle.

(2) FIG. 2 provides the cross section view of the component 6 that fixes the tube to the chassis.

(3) FIG. 3 provides side view of the component 8, sliding rails hanging to the vehicle.

(4) FIG. 4 provides front view of component 9, steel plate or bars that connect 2 spring equipment together near the tire.

(5) FIG. 5 provides side view of the tire, component 10.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

(6) This equipment can be applied to all type of vehicles, e.g., cars, vans and trucks. The material can be steel or composites. The size of equipment or the elasticity of the spring (2) or liquid cylinder (3) needs further experiment based on the vehicle. A pair of tubes (1) is installed to the chassis in left and right of the vehicle symmetrically. The bump (5) can be designed in different ways such as plate or combination of tube. The chassis and frame of the vehicle need some strength enhancement. In case of combination of springs (2) or liquid cylinders (3), the spring (2) or liquid cylinder (3) with soft elasticity should be compressed first.

(7) When the vehicle hit an obstacle or two vehicles collide with each other, the bump (5) will push the spring (2) or liquid cylinder (3) through the movable cylinder fixed to the bump (5). The spring (2) or the liquid cylinder (3) will push the cylinder with the brake pad (4). If the vehicle is running in straight line or almost straight line, the brake pad (4) will hit the tire (10). During this process, the spring (2) or liquid cylinder (3) inside the tube (1) will be compressed to reduce the colliding force. The elasticity of the tire (10) will also reduce the colliding force. If the vehicle is turning left or right with big angle, the brake pad (4) will not hit the tire (10) and the cylinder with the brake pad (4) will be stopped in a position by a stopper in the sliding rails and the reduced colliding force will be passed to the chassis. If the colliding is very heavy, it will also trigger the vehicle to pop up the airbag. In any case, the damage to the vehicle and the driver will be reduced significantly.
