On this operation board 140, be provided with at least and make driving that the driving that utilizes the walking band 120 that driving mechanism carries out begins begin with switch and make the driving that the driving of walking band 120 stops stop using switch.And then, preferably be provided with the switch for the speed that changes walking band 120.As the information that shows, set the remaining time of time when for example showing from motion begins institute's elapsed time or motion beginning in this operation board 140.In addition, also can be presented at the Relationship of Walking (walking distance) on walking band 120 or show by Relationship of Walking (walking distance) being converted into the amount of movement on the short transverse that the distance on short transverse obtains in this operation board 140.That is, in this walking movement machine 100, user U is walking on upward trend, and therefore, being equivalent to user U is in the motion of carrying out stair climbing or the road of climbing the mountain.Therefore, such as the information at the height above sea level 3700m place that also can be shown as the height 600m place that arrives Tokyo clear sky tower (Tokyo Skytree), arrival Fuji etc.
With reference to Fig. 4, the driving mechanism of this walking movement machine 100 is described.
This driving mechanism possesses: drive motor 128, and it is rotated from the supply that civil power receives electric power; Worm screw 126, it is connected with the motor rotation axis 127 of drive motor 128 in the consistent mode in axle center; Worm gear 125, itself and worm screw 126 mesh; Gear 123, it is connected with worm gear 125 in the consistent mode in axle center by rotating shaft 124; And reduction gearing 122, it is set to and gear 123 engagements.Reduction gearing 122 connects in the consistent mode of rotating shaft with the cylinder 121 of front side.Be wound with the walking band 120 of ring-type between the cylinder 130 (slave end) of the cylinder 121 (driving side) of this front side and rear side.That is, in this walking movement machine 100, be provided with as transmission mechanism the worm and gear section that is made of worm screw 126 and worm gear 125, wherein, the revolving force of drive motor 128 is imported in worm screw 126, and worm gear 125 is to walking band 120 output rotary driving forces.
And then, be provided with limiting mechanism 150 in this walking movement machine 100, following situation occurs in these limiting mechanism 150 restrictions, namely, on walking band 120 during walking, walking band 120 moves the distance more than the driving amount that is produced by drive motor 128 towards rear side as user U.Above-mentioned worm and gear section is constituted as this limiting mechanism 150 moves.Below this is at length described.
The worm and gear section that is made of worm screw 126 and worm gear 125 has and is difficult to make the such characteristic of power shaft (rotating shaft of worm screw 126) rotation (the large such characteristic of rotational resistance) by output shaft (rotating shaft of worm gear 125).Can be the braking function of worm and gear section with this characteristics explain.
(in theory) can realize this braking function when angle of friction during greater than the lead angle (helical angle) of worm screw 126.Thereby although angle of friction change and can't obtain exactly according to lubrication state or surface roughness etc.,, in most of the cases known, worm screw 126 can go out in slippages when this lead angle is spent greater than 10.That is, in order to realize braking function, the lead angle of worm screw 126 need to be located at below 10 degree, in the walking movement machine 100 that present embodiment relates to, also the lead angle with worm screw 126 is located at below 10 degree.
Owing to being the lead angle of having set as described above worm screw 126, thereby following situation is limited, that is, on walking band 120 during walking, walking band 120 is moved beyond the distance of the driving amount that is produced by drive motor 128 towards rear side as user U.
In addition, about above-mentioned drive motor 128, on walking band 120 during walking, this drive motor 128 is carried walking band 120 towards rear side as user U in situation from this drive motor 128 to the cylinder 121 of front side that supplied with revolving force by.At this moment, the power that also exist to surpass the revolving force of drive motor 128 is applied to situation on drive motor 128 via walking band 120.So be applied to power on drive motor 128 by user U, produce electric power as the palingenesis of drive motor 128.The palingenesis of such drive motor 128 becomes load for user U, thereby plays a role as brake.
Fig. 5 represents that user U stands in the state that carries out walking on the walking band 120 of this walking movement machine 100.
Like this, user U both feet stand on walking band 120, and operation setting on operation board 140, make that walking band 120 begins to drive begin to drive and use switch, thereby from the front side towards rear side conveying walking band 120.
User U carries out walking with the movement of walking band 120 with matching.At this moment, because walking band 120 tilts, thereby be equivalent to walking (climbing) on upward trend.Therefore, (1) is compared with the situation that walking band 120 flatly arranges and can be increased amount of exercise.And then, as user U on walking band 120 during walking, (2) restriction walking band 120 plays a role towards the restraint braking function of section (worm and gear) that rear side is moved beyond the distance of the driving amount that is produced by drive motor 128, perhaps, (3) when walking band 120 want towards rear side be moved beyond the driving amount that produced by drive motor 128 apart from the time, the regeneration action of drive motor 128 plays a role.In any situation of above-mentioned (1)～(3), the amount of exercise of user U is increased.
Like this, because the walking speed that need not to accelerate walking band 120 just can increase amount of exercise, therefore, do not produce vibration or noise aspect comparatively desirable.In addition, though also can increase at short notice aspect momental comparatively desirable.In addition, are devices of giving the motion as climbing due to walking movement machine 100, therefore, have advantages of following like that, that is, can shorten the front and back length that becomes the walking of walking surface band 120, and then, compare the front and back length that can shorten as much as possible main body frame with existing treadmill.
[the second embodiment]
Next, the walking movement machine 100 that with reference to the accompanying drawings the second embodiment of the present invention is related to describes.
Fig. 6, Fig. 7 represent the walking movement machine 100 that the second embodiment relates to.This walking movement machine 100 has the formation roughly the same with the walking movement machine of the first embodiment shown in Figure 1.But different significantly on the formation of limiting mechanism 150, wherein, limiting mechanism 150 restriction walking bands 120 are moved beyond the distance of the driving amount that is produced by drive motor 128 towards rear side.
In the walking movement machine 100 of the second embodiment, be also during walking, to carry walking band 120 towards rear side as user U in situation from drive motor 128 to the cylinder 121 of front side that supplied with revolving force by on walking band 120.
As shown in Figure 7, as the driving mechanism of walking movement machine 100, in the installed inside of the lower horizontal framework 106 in left side, drive motor 128 is arranged, this drive motor 128 is rotated from the supply that civil power receives electric power.The motor rotation axis 127 of this drive motor 128 is towards fore-and-aft direction, and, be provided with worm screw 126 at the front end of motor rotation axis 127 with being coaxial shape.On the other hand, in the walking band 120 that is wound with ring-type, left end side front side cylinder 121, worm gear 125 is installed with being coaxial shape, this worm gear 125 screws togather with worm screw 126.
Therefore, when drive motor 128 being rotated drive, its rotary driving force is passed to the cylinder 121 of front side via worm screw 126, worm gear 125, make thus cylinder 121 rotations of front side, thereby walking band 120 is moved towards the rear from the place ahead.
At this moment, also exist walking by user U to make over the power of the rotary driving force of drive motor 128 and be applied to situation on drive motor 128 via walking band 120.So be applied to power on drive motor 128 by user U, produce electric power (generation counter electromotive force) as the palingenesis of drive motor 128.The palingenesis of such drive motor 128 becomes load for user U, thereby plays a role as brake.In the second embodiment, this palingenesis is utilized as limiting mechanism 150.That is, limiting mechanism 150 uses the counter electromotive force of drive motor.
At this, the worm and gear section that is made of worm screw 126 and worm gear 125 does not possess the function as limiting mechanism 150, wherein, following situation occurs in limiting mechanism 150 restrictions, namely, on walking band 120 during walking, walking band 120 is moved beyond the distance of the driving amount that is produced by drive motor 128 towards rear side as user U.
In addition, the motor rotation axis 127 of above-mentioned drive motor 128 is also outstanding towards the rear, speedometer (speed detection sensor) 210 is installed on this rear ledge, and this speedometer 210 detects the rotating speed of motor rotation axis 127, the translational speed of walking band 120 in other words.Can adopt revolution counter that has used photoelectric sensor etc. as this speedometer 210.
But the limiting mechanism 150 in the walking movement machine of the second embodiment is different from the first embodiment, and it is to utilize the mode of electricity to control the rotary driving force of drive motor 128 by control part 200.In other words, limiting mechanism 150 possesses control part 200, this control part 200 is constituted as the power input short circuit to each other by making drive motor 128, thereby the counter electromotive force that produces in drive motor 128 is played a role as the brake force to drive motor 128, and then control to each other by the time of short circuit for the power input that makes drive motor 128 for control part 200.
The inside of the lower horizontal framework 106 on the left of this limiting mechanism 150 is configured in and the rear side of drive motor 128.
Fig. 8 is the block diagram of limiting mechanism 150.
As shown in Figure 8, control part 200 is made of rectification part 201 and PWM control part 202, wherein, the civil power (interchange) that rectification part 201 will be supplied with from the outside converts direct current to and is supplied to drive motor 128, and PWM control part 202 is controlled the rotary driving force of drive motor 128 according to pwm pulse signal (Pulse WidthModulation Pulse Signal).
CPU205 produces the revolving force that is used for drive motor 128 and carries out the pwm pulse signal that PWM controls, and can change the pulse width of this pwm pulse signal.From the signal that is arranged on the speedometer 210 on drive motor 128 (namely, the velocity information of walking band 120) be imported in CPU205, when the speed of walking band 120 during lower than setting value, the pwm pulse signal that has amplified from the CPU205 output pulse width, when the speed of walking band 120 during higher than setting value, the pwm pulse signal that has dwindled from the CPU205 output pulse width.
Be imported into the gate pole (gate) of thyristor 203b via half-bridge gate driver 207 from the pwm pulse signal of this CPU205 output, thus by thyristor 203b is switched (switching), the voltage (voltage between the power input of drive motor 128) that is attached on drive motor 128 is changed, thereby rotating speed, the rotary driving force of drive motor 128 are controlled.That is to say, pwm pulse signal plays a role as the signal of the revolving force of controlling drive motor 128.
On the other hand, the pwm pulse signal of exporting from this CPU205 also is imported into phase inverter 206, and the PWM rp pulse signal of exporting from phase inverter 206 is imported into the gate pole of thyristor 203a via half-bridge gate driver 207.When the gate pole of thyristor 203a became High (=1), the power input of drive motor 128 became short-circuit condition.When wanting to make drive motor 128 rotation that is short-circuit condition, produce counter electromotive force in this drive motor 128, become thus the not voluble situation of motor rotation axis 127 of drive motor 128, thereby with respect to the 120 performance braking actions of walking band.That is to say, PWM rp pulse signal is the signal after making pwm pulse signal anti-phase, and plays a role as the signal of drive motor 128 being braked control.
In addition, when the pwm pulse signal from CPU205 be all Low (for example, although be supplied to civil power but do not pressed start button, thereby output does not drive the state of the instruction of walking band) time, pwm pulse signal is inverted in phase inverter 206, and is output as PWM rp pulse signal.Because this PWM rp pulse signal all becomes High, therefore, drive motor 128 can not dally according to the PWM rp pulse signal of exporting.
No matter that is to say, be when the walking band stops or walking band when driven, when drive motor 128 drives, all becomes the situation that braking function plays a role with respect to walking band 120.
And then the limiting mechanism 150 in the walking movement machine of the second embodiment possesses overcurrent and prevents circuit 208, and this overcurrent prevents that circuit 208 from preventing the overcurrent that flows in drive motor 128.
Specifically, overcurrent prevents that the distribution that circuit 208 and source side from thyristor 203b diverge out is connected, and the current value when this overcurrent prevents that 208 pairs of drive motors 128 of circuit from driving monitors.When the current value when drive motor 128 drives had surpassed setting, overcurrent prevented circuit 208 output Low (=0) (output High (=1) when overcurrent not detected).Overcurrent prevent circuit 208 output and from the pwm pulse signal of CPU205 output be carried out the adder 209 of the input side that is arranged at phase inverter 206 " with " process (AND processing), and its result is imported in phase inverter 206 and half-bridge gate driver 207.
The method of controlling for the rotary driving force that uses 150 pairs of drive motors 128 of above-mentioned limiting mechanism, the braking function of limiting mechanism 150 is narrated in other words.
At first, begin to use switch with similarly on operation board 140, the driving that make walking band 120 begin to drive of operation setting of the first embodiment, thereby carry walking band 120 from the front side towards rear side.Then, user U carries out walking (with reference to Fig. 5) with the movement of walking band 120 with matching.
At this moment, because walking band 120 tilts, thereby be equivalent to walking (climbing) on upward trend.When user U carried out walking, when the translational speed of walking band 120 departs from certain value when above from setting value, limiting mechanism 150 moved and changes the rotary driving force (being rotating speed in other words) of drive motor 128.
Specifically, the CPU205 output of PWM control part 202 is used for the translational speed of walking band 120 is controlled to be the pwm pulse signal of setting value (for example 3.0km/h), this pwm pulse signal is imported into the gate pole of thyristor 203b via half-bridge gate driver 207, thus thyristor 203b is switched.Controlling by this PWM makes the translational speed of walking band 120 be maintained setting value.
But, when becoming the situation of the translational speed of walking band 120 slack-off (for example 2.8km/h) due to the walking of user U, Negotiation speed meter 210 is measured the translational speed (translational speed after slack-off) of walking band 120, and the speed of actual measurement is input in CPU205.CPU205 exports pwm pulse signal, this pwm pulse signal is imported into the gate pole of thyristor 203b via half-bridge gate driver 207, thus thyristor 203b is switched, wherein, enlarged from the pulse width of the pwm pulse signal of CPU205 output and accelerate with the translational speed that makes walking band 120 and return to the corresponding width of setting speed required pulse width.At this moment, control electric current (acceleration electric current) is mobile as shown in the chain-dotted line of Fig. 8.Control by this PWM, the output of self-rectifying in the future section 201 is controlled to be assigned voltage and is supplied to drive motor 128, thereby makes the translational speed of walking band 120 be maintained setting value.
On the other hand, when becoming due to the walking of the user U translational speed of walking band 120 and accelerate the situation of (for example 3.2km/h), Negotiation speed meter 210 is measured the translational speed (translational speed after accelerating) of walking band 120, and the speed of actual measurement is input in CPU205.CPU205 output is slack-off and return to the pwm pulse signal that setting speed (setting value) required pulse width has dwindled its pulse width accordingly with the translational speed that makes walking band 120, this pwm pulse signal is imported into the gate pole of thyristor 203b via half-bridge gate driver 207, thereby thyristor 203b is switched.
Simultaneously, also export the PWM rp pulse signal after making pwm pulse signal anti-phase by phase inverter 206, and this PWM rp pulse signal is imported into the gate pole of thyristor 203a via half-bridge gate driver 207, thereby thyristor 203a is switched.By being switched, thyristor 203a make drive motor 128 become short-circuit condition, when wanting to make drive motor 128 rotation under this state, and palingenesis play a role (generation counter electromotive force) in this drive motor 128.At this moment, control electric current (stalling current) is mobile as shown in the dotted line of Fig. 8.This palingenesis becomes load for user U, thereby to wanting, the action of walking band 120 fast moving is played a role as brake.That is to say, make the translational speed of walking band 120 return to setting value.
Like this, thereby by the pulse width of dwindling pwm pulse signal and the pulse width of amplifying PWM rp pulse signal, following situation is limited, namely, on walking band 120 during walking, walking band 120 is moved beyond the distance of the driving amount that is produced by drive motor 128 towards rear side as user U.
In addition, when the pwm pulse signal that the translational speed of walking band 120 slack-off and output pulse width has broadened, also export the PWM rp pulse signal after making this pwm pulse signal anti-phase by phase inverter 206, and this PWM rp pulse signal is imported into the gate pole of thyristor 203a via half-bridge gate driver 207.But because the pulse width of PWM rp pulse signal is narrow, therefore, braking action plays a role hardly.
But, the overcurrent that flows in drive motor 128 when driving walking band 120 in the situation that make drive motor 128 rotations, overcurrent prevents circuit 208 from the source side inflow overcurrent of thyristor 203b.When preventing that by overcurrent circuit 208 from detecting this overcurrent, overcurrent prevents circuit 208 output Low (=0), this output 0 be carried out adder 209 with pwm pulse signal from CPU205 output " with " processing.Because the output of adder 209 when pwm pulse signal is the signal of any pulse width is all output 0, therefore, thyristor 203b becomes disconnection (OFF) state, thyristor 203a becomes connection (ON) state, thus, the braking action with respect to walking band 120 continues to play a role.
Effect by above-mentioned limiting mechanism 150 makes walking band 120 move with roughly fixing speed, thereby can not produce large vibration or noise, and, even also can guarantee effective amount of exercise in shorter run duration.
In addition, the formation of other of the second embodiment and the action effect of bringing into play and the first embodiment are roughly the same, thereby description is omitted.
Should think that all aspects of above disclosed embodiment are illustration, rather than restrictive content.Especially not clear and definite disclosed item in this disclosed embodiment, such as the size of operating condition or operating condition, various parameter, structure member, weight, volume etc. do not exceed the scope that persons skilled in the art are implemented usually, but the value that adopts one of ordinary skill in the art easily to expect.
