DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0017] Referring to FIGS. 3 and 4, the training device 1 of the
present invention comprises a motor 10, a torque output unit 20 and
a control unit 30. The motor 10 includes a sensor member 11
connected therewith which detects the angular degree and speed of
the motor 10 and is electrically connected to the control unit 30
which includes a controller 31 and a control panel 32 so as to
control the motor 10 by input commands via the control panel
32.
[0018] The torque output unit 20 is connected with an output shaft
of the motor 10 and includes a speed reduction unit 21 and a
tension unit 22. The speed reduction unit 21 includes a first speed
reduction wheel 211 which is connected to the output shaft of the
motor 10 and a second speed reduction wheel 212. A transmission
belt 213 is connected between the first and second speed reduction
wheels 211, 212. The small output torque with high revolutions can
be transferred to high torque with low revolutions. The second
speed reduction wheel 212 is connected with the tension unit 22
which includes a tension wheel 220. A cable 221 is connected to the
tension wheel 220 and a handle 222 is connected to the cable 221.
The user holds the handle 222 and pulls the cable 221 to transfer
an operation force to the motor 10 via the tension unit 22 and the
speed reduction unit 21, and the motor 10 generates a force to the
user according to the commands via the control panel 32.
[0019] The motor 10 is a brushless permanent magnet motor and
includes the features including maximum power (Watt)/horse power
(hp), maximum torque, and maximum inertial, maximum speed. The
design parameters of the power and the inertial is the diameter of
the motor 10, the speed is the number of magnetic poles and the
torque is the thickness of the silicon disks. All of the parameters
are set when the motor 10 is manufactured and the maximum
revolutions (Nmax) and the torque constant (kt) are pre-set
values.
Kt=C.times.VD/Nmax; [0020] VD: terminal voltage of the motor [0021]
C: constant=9.55 [0022] kt=torque constant of the motor (N-M)/A
[0022] Tm=A.times.kt; [0023] Tm: output torque of the motor (N-M);
[0024] A: input current of the motor (Amp).
[0025] The output torque of the motor is proportional to the input
current of the motor so that when controlling the current of the
motor 10, the output torque of the motor 10 is controlled. The
users can have higher output torque by inputting higher current via
the operation of the control panel 32.
[0026] As shown in FIG. 5 which shows the relationship between the
torque and time of the training device 1 of the present invention,
wherein:
[0027] The radius of the tension wheel 220: r3;
[0028] The ratio of the speed reduction at the output shaft of the
motor 10 is r2/r1;
[0029] The radius of the first speed reduction wheel 211: r1;
[0030] The radius of the second speed reduction wheel 211: r2;
[0031] The operation force from the user: F;
[0032] The torque applied to the tension wheel 220 from the user:
Tr;
Tr=F.times.r3;
Fr=Tr/r2=(F.times.r3)/R2;
[0033] Tr applies the force Fr to the second speed reduction wheel
212.
[0034] The torque that the motor 10 has to generate is Tm so as to
balance the torque transferred to the motor 10 via the speed
reduction unit 21.
Tm=Fr.times.r1=(F.times.r3.times.r1)/r2;
[0035] Tm is the upper limit of the torque that the motor outputs
and set by users.
[0036] When the user has not yet apply a force to the handle 222,
the sensor member 11 does not detect any operation of the motor 10
so that the controller 30 does not supply current to the motor 10.
When the user applies an operation force which is less than the Tm,
the controller 31 inputs a current to the motor 10 to against and
balance the operation force.
[0037] When the operation force applies a torque which is equal to
the Tm, the user cannot pull the cable 221 because the two forces
are in a balance status.
[0038] When the operation force applies a torque which is larger
than the Tm, because the controller 31 commands the motor 10 to
generate the torque now is smaller than the torque applied by the
user, the cable 221 and the handle 222 are pulled away from the
tension unit 22 by the user. The sensor member 11 detects the angle
that the motor 10 is pulled and the controller 31 memorizes the
angle.
[0039] When the operation force applies a torque which is smaller
than the Tm, because the controller 31 commands the motor 10 to
generate the torque now is larger than the torque applied by the
user, the cable 221 and the handle 222 are pulled toward the
tension unit 22 by the motor 10.
[0040] Therefore, the user's muscles are exercised by the fixed Tm
from the motor 10.
[0041] The training device 1 includes a second operation mode which
uses the controller 31 to set the output torque form the motor 10
according to the Tm, and further sets the torque periodically in a
form of sine or cosine waves.
[0042] t: the period of time of a cycle (unit: seconds)
[0043] f=1/t the frequency of the torque (unit: Hz)
[0044] .DELTA.T: the change of the torque
[0045] When t=0, the Tm generated by the motor 10 is equal to the
torque by the operation force of the user, the cable 221 is
remained still.
[0046] When the value of t is between 0 and t/2, the force
generated by the motor 10 is larger than the operation force. When
t=t/4, the maximum torque is Tm+.DELTA.T, the cable 221 is pulled
by the motor 10.
[0047] When the value of t is equal to t/2, the torque Tm generated
by the motor 10 is equal to the torque by the user, the cable 221
is remained still again.
[0048] When the value of t is between t/2 and t, the force
generated by the motor 10 is smaller than the operation force. When
t=3t/4, the minimum torque is Tm-.DELTA.T, the cable 221 is pulled
by the user.
[0049] The adjustment of the frequency f and the change of the
torque .DELTA.T, the user's muscles and the reaction of the user's
nerves is exercised.
[0050] FIG. 7 shows a second embodiment of the training device 1,
wherein the tension unit 22 is replaced by a crank 223 and the user
can use hands or feet to operate the crank 223 to drive the speed
reduction unit 21. When the user's input force is larger than the
force generated by the motor 10, the motor 10 is rotated in
opposite direction by the user. When the user's input force is
smaller than the force generated by the motor 10 or the user does
not applies any force on the crank, the motor 10 does not generate
torque a and the crank 223 is remained still.
[0051] FIGS. 8 and 9 show a third embodiment of the training device
1, wherein the tension unit 22 is replaced by a driving shaft 231
which is connected with the second speed reduction wheel 212. An
endless belt 232 is connected between the driving shaft 231 and
another shaft 233, and a support board 234 is located beneath of
the top surface of the endless belt 232. The training device 1 can
be used as a treadmill
[0052] While we have shown and described the embodiment in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention.
