piston and filled with high viscosity of the damping oil, and the
piston would pressurize the damping oil through a valve with a
small aperture to generate a compressive or tensile resistance for
absorbing vibration energy. In this case, the dampers would
generate heat by mechanical energy caused by repeating shocks of
the dampers. Thus the damping oil temperature would be raised. If
the heat could not be effectively dissipated, the function of
dampers would be affected.

[0011] FIG. 2 is a first operation diagram of the vibration energy

[0012] FIG. 3 is a second operation diagram of the vibration energy

DETAILED DESCRIPTION OF THE INVENTION
[0013] To more clearly describe a vibration energy harvest device
according to the present invention, embodiments of the present
invention will be described in detail with reference to the
attached drawings hereinafter.
[0014] First of all, the structure of the vibration energy harvest
device will be described. With reference to FIG. 1, there is shown
a structure diagram of the vibration energy harvest device
according to the present invention. As shown in FIG. 1, the
vibration energy harvest device consists of an outer cylinder
module 1, an inner cylinder module 2, a valve module 3, a moveable
piston 4, a piston rod module 5, a hydraulic motor 6, and an
electricity generating unit 7.
[0015] In this vibration energy harvest device, the outer cylinder
module 1 has a cover 11 on one side itself; the inner cylinder
module 2 is disposed in the outer cylinder module 1, wherein there
is a first storage space (A) formed between the outer cylinder
module 1 and the inner cylinder module 2, and there is an opening
21 formed on the inner cylinder module 2; the valve module 3 is
coaxially connected to the other side of the outer cylinder module
1 and the inner cylinder module 2, wherein the valve module 3 is a
disc structure, and has a plurality of shuttle valves in the
internal thereof; the moveable piston 4 disposed in the inner
cylinder module 2, wherein there is a second storage space (B)
formed between the moveable piston 4 and the valve module 3; a
piston rod module 5 is disposed in the inner cylinder module 2,
wherein the piston rod module 5 comprises: a piston rod 51, which
is extended through the cover 11 and there is a third storage space
(C) formed between the piston rod 51 and the inner cylinder module
2, wherein the third storage space (C) is connected to the first
storage space (A) by the opening 11; and a fixed piston 52, which
is disposed in the inner cylinder module 2, and connected to the
piston rod 51, wherein there is a accumulating chamber (D) formed
between the moveable piston 4 and the fixed piston 52, wherein the
accumulating chamber (D) is an enclosure space, and the enclosure
space could be filled with air or nitrogen for regulating pressure
; the hydraulic motor 6 is coaxially connected to the valve module
3 from outside of the inner cylinder module 2, and disposed in the
outer cylinder module 1; the electricity generating unit 7 is
connected to the hydraulic motor 6 from the outside of the outer
cylinder module 1.
[0016] Therefore, through above descriptions, the structure of the
vibration energy harvest device has been introduced completely and
clearly. Next, the flow direction of the damping oil and the
function of energy recycle would be explained. As shown in FIG. 2,
which is a first operation diagram of the vibration energy harvest
device according to the present invention. As the dotted arrow
shown in FIG. 2, when the piston rod module 5 is applied an
external thrust, the piston rod 51 would push the accumulating
chamber (D), the accumulating chamber (D) would push the moveable
piston 4, and the moveable piston 4 finally push the damping oil in
the second storage space (B) to the valve module 3. In this time,
the pressure of the inner cylinder module 2 is more than the outer
cylinder module 2, so the damping oil flows into the valve module
3, and flows out of an opening 31 by switching of the Shuttling
valve 33. Thus, the damping oil would also drive the hydraulic
motor 6 to generate electricity for electricity generating unit 7.
Then, the damping oil would flow into an opening 32, through the
first storage space (A), and the opening 21, finally to the third
storage space (C).
[0017] Then, as shown in FIG. 3, which is a second operation
diagram of the vibration energy harvest device according to the
present invention. As the dotted arrow shown in FIG. 3, when the
piston rod module 5 is applied an external pulling force, the
piston rod 51 would push the damping oil in the third storage space
(C) from the opening 21 to the first storage space (A). In this
time, the pressure of the outer cylinder module 1 is more than the
inner cylinder module 2, so when the damping oil flows into the
opening 31 of the valve module 3 by switching of the Shuttling
valve 33. Thus, the damping oil would also drive the hydraulic
motor 6 to generate electricity for electricity generating unit 7.
Then, the damping oil would flow into the opening 32, through the
second storage space (B).
[0018] Therefore, through above descriptions, when the piston rod
51 in the vibration energy harvest device is pushed and pulled to
make the damping oil flow to the hydraulic motor 6 to drive the
rotor of the hydraulic motor 6. In this case, if there is no valve
module 3, the rotor would turn clockwise rotation to
counter-clockwise rotation, and the rotation of the rotor would
slow down, stop, and restart, thus it would reduce the efficiency
of electricity generation, and the rotor would be susceptible to
damage. So the vibration energy harvest device according to the
present invention is newly added the valve module 3, when the
piston rod 51 in the vibration energy harvest device is pushed and
pulled, the damping oil would always drive the rotor of the
hydraulic motor 6 in the same rotation direction to improve the
efficiency of electricity generation.
[0019] So that, according to above descriptions, the present
invention has been completely and clearly disclosed; and in
summary, the main advantage of the present invention is that with
newly added hydraulic motor and electricity generating unit, the
mechanical energy and thermal energy generated during the vibration
could be recycled, and the power generation efficiency could be
effectively improve. Moreover, by using an ameliorating valve
module and removing the damping hole in the prior art, no matter
the damping oil flows from inner cylinder module through hydraulic
motor to outer cylinder module or the contrary direction, the
flowing damping oil could avoid the hydraulic motor from
reciprocating to improve the power generation efficiency.
[0020] The above description is made on embodiments of the present
invention. However, the embodiments are not intended to limit scope
of the present invention, and all equivalent implementations or
alterations within the spirit of the present invention still fall
within the scope of the present invention.
