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 hydraulic cylinder that
absorb the colliding force, when the vehicle bumps to obstacle or
two vehicles collide with each other. The reduced colliding force
will be transferred to the chassis or frame of the vehicle. This
equipment can be used on both front and rear of the vehicle.
Combination of springs or hydraulic 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 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.

Description
TECHNICAL FIELD
[0001] The present invention generally relates to improvements in
protecting both vehicles and drivers utilizing the elasticity of
spring and/or hydraulic cylinder from either front and/or rear over
collision accidents. The spring or liquid in hydraulic cylinder
will be compressed to reduce the colliding force when the vehicle
hit an obstacle or collides with each other. The reduced colliding
force will be transferred to the chassis or frame of the vehicle.
There is no change for the current airbag protection system.
BACKGROUND ART
[0002] 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 hit
an obstacle or collides with each other, the auto 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.
In case the collision is not heavy, the vehicle body or auto parts
still could be damaged.
SUMMARY OF THE INVENTION
[0003] An object of the present invention is to utilize the
elasticity of spring or hydraulic cylinder to reduce the colliding
force and transfer the reduced colliding force to the chassis or
frame to protect the vehicle and improve the protection over
drivers. The current airbag protection system is not changed.
Overall it will significantly reduce the damage for both vehicles
and drivers in the collision accidents.
[0004] In accordance with the present invention, there is a pair of
hydraulic cylinders connected by a bar that is fixed to the chassis
of the vehicle. Generally, the hydraulic cylinder is fixed to the
bottom of the chassis. The piston rod is fixed to the front or rear
bump, which is changed as a movable part from the current fixed
part. The bumper can be constructed in different shape, e.g.,
combination of tubes, or a plate. There are 1 or 2 or 4 sliding
rails that connect the bumper and the bar on another end. The
sliding rails are fixed to the bumper on one end and pass through
the holes in the bar. There is a stopper that is made of a small
plate or tubes beside the bar to prevent the front or rear bump
moving toward front or rear direction. The height and width of the
hole in the bar should be big enough to prevent the sliding rails
being stuck to the holes, while the lower bottom of the hole should
be slightly lower than the low bottom of the sliding rails so the
sliding rails are sitting right on top of the hole bottom. The
sliding rail can be tube or bar. An optional spring or combination
of springs are connected the front bump and the bar.
[0005] In accordance with the present invention, when the vehicle
hits an obstacle or collide with another vehicle, the bump will
push the spring or liquid in the hydraulic cylinder through the
piston, which will reduce the colliding force by compression. If
the collision is heavy, the check valve in the hydraulic cylinder
should be opened by the high fluid pressure and the liquid will
flow out of the bottom chamber. When the fluid pressure goes down
to a low threshold, the valve is closed and the liquid will be
compressed again. This process will significantly reduce the
colliding force, which will be transferred to the chassis of the
vehicle. If the collision is not heavy, there should be no any
damage to both vehicle and driver. If the colliding is very heavy,
it might trigger the vehicle to pop up the airbag. In any case, it
will significantly reduce the damage to the vehicle and driver.
[0006] In accordance with the present invention, this equipment can
be installed on both front and rear of the vehicle with similar
design architecture for existing vehicle. For new vehicles, the
vehicle might need to change the chassis and frame design to attach
the equipment better. Chassis or frame strength enhancement might
be needed for either existing or new vehicle.
[0007] In accordance with the present invention, multiple springs
with different elasticity can be used. The combination of multiple
springs with hydraulic cylinders will reduce the colliding force
smoothly with the spring or hydraulic cylinder of soft elasticity
being compressed first.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] FIG. 1 provides the primary cross-section vertical view of
the equipment from top of the vehicle.
[0009] FIG. 2 provides the horizontal cross-section view of the
hydraulic cylinders (1) from left side of the vehicle.
[0010] FIG. 3 provides the horizontal cross-section view of the
sliding rails (10) and optional springs from left side of
vehicle.
[0011] Note: most components of the equipment could be tube or
bar.
[0012] Following are the detailed information about the components
in the drawings. [0013] 1. Hydraulic Cylinder: it is a general
single-acting cylinder with a spring (11) and a check valve (3).
The check valve (3) is opened when the fluid pressure hit high
threshold and closed when the fluid pressure hit low threshold.
[0014] 2. Piston rod: it is fixed to the front or rear bumper (6)
on one end and connected to the piston (12) on another end. [0015]
3. Check valve: it is opened when the fluid pressure hit high
threshold and the fluid will flow out of the bottom chamber. The
valve is closed when the fluid pressure hit low threshold. [0016]
4. Bottom rod: it fixes the hydraulic cylinder (1) to the bar (7).
[0017] 5. Stopper: it is made of tubes or small plate on end of the
sliding rails and stops front or rear bumper moving toward the
front or rear direction. [0018] 6. Front or rear bumper: it can be
designed as a plate or combination of tubes and bars. [0019] 7.
Bar: it connects 2 hydraulic cylinders (1) and attaches them to the
chassis by another tube or bar or screw rod (8). [0020] 8. Bar or
tube or screw rod: it is fixed to the chassis. [0021] 9. Spring or
multiple springs: it connects the bumper (6) and the bar (7) and it
is optional. [0022] 10. Sliding rails: it can be 1 or 2 or 4 tubes
or small bar. It is fixed to the bumper (6) on one end and passes
through the hole in the bar (7) on another end. [0023] 11. Spring
inside the hydraulic cylinder: it retracts when the force on front
or rear bumper (6) is removed. [0024] 12. Piston: it is connected
to the piston rod on one side and pushes the fluid in the bottom
chamber on another side. [0025] 13. Fixing parts: it can be a screw
rod that fixes the hydraulic cylinder to the chassis.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0026] 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 (9) (11) or
hydraulic cylinder (1) needs further experiment based on the
vehicle. Generally, the equipment is installed at the bottom of the
vehicle, either front or rear. The bumper (6) can be designed in
different ways such as plate or combination of tube and bar. The
chassis and frame of the vehicle need some strength enhancement. In
case of combination of springs (9), the springs (9) or hydraulic
cylinder (1) with soft elasticity should be compressed first to
reduce the colliding forces smoothly.
[0027] When the vehicle hit an obstacle or two vehicles collide
with each other, the bumper (5) will push the spring (9) or liquid
in the hydraulic cylinder (1) by the piston through piston rod
fixed to the bumper (5). If the fluid pressure hit high threshold,
the check valve will be opened and the fluid will flow out of the
bottom chamber. If the fluid pressure goes down to a low threshold,
the check valve will be closed. During this process, the spring (9)
or liquid inside the hydraulic cylinder (1) will be compressed to
absorb the colliding force. The reduced colliding force will be
transferred to the chassis by a bar or tube (8). If the colliding
is very heavy, it might trigger the vehicle to pop up the airbag.
In any case, the damage to the vehicle and the driver will be
reduced significantly.
