The present invention generally relates to improvements in protecting both vehicles and drivers over collision accidents utilizing the elasticity of springs, tube and stretchy material from either front, rear, side and/or corner. The tubes will be deformed, spring and the stretchy material will be compressed to absorb the energy and reduce the colliding force when the vehicle hits an obstacle or collides with each other. The reduced colliding force will be passed to a frame of tubes or bars that is attached to the chassis of the vehicle. The chassis of the vehicle is almost incompressible. If the vehicle hits the obstacle, the vehicle could push the obstacle forward or the vehicle bumps back. If two vehicles hit each other, both vehicles could bump back or one vehicle pushes another vehicle forward.
There is no change for the current airbag protection system.
Currently, most vehicles use airbag to protect the drivers in collision accidents. There is limitation with airbag protection. Airbag only protects driver, but not vehicle. When the vehicle hits an obstacle or collide with each other, the vehicle body and auto parts can be damaged. In case of heavy collision accident, not only the vehicles are seriously damaged, but also the drivers could be seriously injured or even killed due to the strong colliding force. Even in case the collision is not heavy, the vehicle body or auto parts are still damaged.
An object of the present invention is to utilize the elasticity of springs, tube or bar made of stretchy material to absorb the energy and reduce the colliding force. Combination of springs with stretchy material can reduce the colliding force more smoothly and handle heavy collision better. The reduced colliding force is passed to the chassis from a frame of tubes or bars that is attached to the chassis. The current airbag protection system is not changed. Overall it will significantly reduce the damage for both vehicles and drivers in the collision accidents.
In accordance with the present invention, there are single or multiple tubes with stretchy material fixed to a frame of tubes or bars that is attached to the chassis of the vehicle. The outer tube is more stretchable than the inner tube is. The tubes with stretchy material can be replaced with cubic shape and the front cubic bar is more stretchable than the back cubic bar is. Multiple springs can be installed between two plates with sliding slots. Combination of springs and stretchable material can be installed between two plates with sliding slots.
In accordance with the present invention, when the vehicle hits an obstacle or collides with another vehicle, the tubes or cubic bars made of stretchy material or springs will be deformed and compressed to absorb the energy. The reduced colliding force will be passed to a frame of tubes or bars that is attached to the chassis of vehicle. If the collision is not heavy, there should be no any damage to both vehicle and driver. If the collision is heavy, it might cause the vehicle turning back. It might still trigger the vehicle to pop up the airbag. In any case, it will significantly reduce the damage to the vehicle and driver.
In accordance with the present invention, this equipment can be installed on front, rear, or side of the vehicle with similar design architecture. The equipment can be installed behind the existing bumper that might needs some design modification. Some vehicles might need to change the chassis and frame design to attach the equipment properly.
In accordance with the present invention, the equipment can have multiple tubes with different size. The outer tube will be deformed and compressed first. Such kind of combination will reduce the colliding force smoothly.
In accordance with the present invention, the equipment can have multiple cubic bars. The front cubic bar will be deformed and compressed first. Additional springs can be combined to the cubic bars. Such kind of combination will reduce the colliding force smoothly.
There are nine figures in the attached drawings.
Following are the detailed information about the primary components of the equipment.
This equipment can be applied to all type of vehicles, e.g., cars, vans and trucks. The material of the tubes (2) (3) or stretchable cubic bars (11) (12) needs to be sponge, rubber or similar stretchable material. The size of equipment needs further experiment based on the vehicle. The equipment can contain tubes (2) (3) with different size, the tube with big size will be deformed and compressed first. The equipment can also contain multiple stretchable cubic bars (11) (12), the cubic bar (12) at front will be compressed first. For some vehicles, the safe equipment can be installed behind the existing bumper while the bumper needs some modification. For some vehicles, the chassis (4) of the vehicle need some design change or strength enhancement.
When the vehicle hit an obstacle or two vehicles collide with each other in straight line or almost straight line, the bumper will push the outer tube (2) and inner tube (3). The tubes (2) (3) will be deformed and compressed to absorb the energy. If the tubes are replaced with cubic bars (11) (12), the front bar (12) will be compressed first, then the bar (12) behind the front bar will be compressed. If the tubes are replaced by springs (6), the front plate (7) will be pushed and move forward through the sliding slots (10). The front plate (7) will push the springs (6) and the springs (6) will be compressed. The springs (6) can also be combined with the stretchable cubic bars (11) (12). Both springs (6) and the stretchable bars (11) (12) will be compressed. During those processes, the compression of cubic bars (11) (12) and springs (6) will absorb the energy and reduce the colliding force.
The reduced colliding force will be passed to the chassis (4) by the frame (1) (5). If the colliding is very heavy, it will also trigger the vehicle to pop up the airbag. In any case, the damage of the vehicle and the driver from the collision accidents will be reduced significantly.
