Rectification part 201 is by diode 204 bridge joints (bridge connection) are formed.
PWM control part 202 has: the thyristor 203 of MOS-FET (mos field effect transistor) etc., the pulse width of pwm pulse signal is changed to the CPU (central proces sing unit, central processing unit) 205 of desirable width and by the anti-phase phase inverter (inverter) 206 of this pwm pulse signal.In addition, PWM control part 202 also possesses half-bridge gate driver (half-bridge gate driver) 207 and overcurrent prevents circuit 208.
In PWM control part 202, mode with series connection disposes two thyristors 203, and, the drain electrode of one of them thyristor 203a (drain) side is connected with the side of the positive electrode distribution (the positive output side of rectification part 201) of drive motor 128, the source electrode of this thyristor 203a (source) side is connected with the 0V side distribution of drive motor 128.And then, the drain side of another thyristor 203b is connected with the source side of thyristor 203a, the source side of this another thyristor 203b is connected with the 0V outlet side of rectification part 201.
CPU205 produces the pwm pulse signal for the revolving force of drive motor 128 is carried out to PWM control, 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 (, the velocity information of walking band 120) be imported in CPU205, when the speed of walking band 120 is during lower than setting value, the pwm pulse signal having amplified from CPU205 output pulse width, when the speed of walking band 120 is during higher than setting value, the pwm pulse signal having dwindled from CPU205 output pulse width.
From the pwm pulse signal of this CPU205 output, via half-bridge gate driver 207, be imported into the gate pole (gate) of thyristor 203b, thus by thyristor 203b is switched to (switching), the voltage (voltage between the power input of drive motor 128) that makes to be applied on drive motor 128 changes, thereby the rotating speed of drive motor 128, rotary driving force are controlled.That is to say, pwm pulse signal plays a role as the signal of controlling the revolving force of drive motor 128.
On the other hand, from the pwm pulse signal of this CPU205 output, be also imported into phase inverter 206, from the PWM rp pulse signal of phase inverter 206 outputs, via half-bridge gate driver 207, be imported into the gate pole of thyristor 203a.When the gate pole of thyristor 203a becomes High (=1), the power input of drive motor 128 becomes short-circuit condition.When wanting to make to be drive motor 128 rotation of short-circuit condition, in this drive motor 128, produce counter electromotive force, become thus the not voluble state of motor rotation axis 127 of drive motor 128, thereby for 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 drive motor 128 being braked to the signal of controlling.
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 exported PWM rp pulse signal.
No matter that is to say, be when walking band stops or when walking band is driven, when drive motor 128 drives, all becomes the state 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, this overcurrent prevents that circuit 208 from preventing the overcurrent that flows in drive motor 128.
Particularly, overcurrent prevents that the distribution that circuit 208 diverges out with source side from thyristor 203b is connected, and 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 has surpassed setting, overcurrent prevents circuit 208 output Low (=0) (exporting High (=1) when overcurrent not detected).Overcurrent prevent circuit 208 output and from the pwm pulse signal of CPU205 output the adder 209 of input side that is arranged at phase inverter 206, carried out " with " process (AND proces sing), 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.
First, start with switch with the similarly operation setting driving on operation board 140, that make walking band 120 start to drive of the first embodiment, thereby carry walking band 120 from 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.
Now, because walking band 120 tilts, thereby be equivalent to walking (climbing) on upward trend.When user U carries out walking, when the translational speed of walking band 120 departs from certain value when above from setting value, limiting mechanism 150 carries out work and changes the rotary driving force (being rotating speed in other words) of drive motor 128.
Particularly, the CPU205 output of PWM control part 202 is for controlling for example, pwm pulse signal for setting value (3.0km/h) by the translational speed of walking band 120, this pwm pulse signal is imported into the gate pole of thyristor 203b via half-bridge gate driver 207, thus thyristor 203b is switched.By this PWM, control and make the translational speed of walking band 120 be maintained setting value.
But, for example, when becoming the situation of the translational speed of walking band 120 slack-off (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.Now, 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, from the pulse width of the pwm pulse signal of CPU205 output, expanded and accelerated with the translational speed that makes walking band 120 and return to the corresponding width of setting speed required pulse width.Now, control electric current (acceleration electric current) is mobile as shown in the chain-dotted line in Fig. 8.By this PWM, control, the output of self-rectifying portion 201 is in the future controlled as 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, for example, when becoming due to the walking of the user U translational speed of walking band 120 and accelerate the situation of (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.Now, 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 thyristor 203a is switched and to make drive motor 128 become short-circuit condition, and, when wanting to make drive motor 128 rotation under this state, palingenesis play a role (generation counter electromotive force) in this drive motor 128.Now, control electric current (stalling current) is mobile as shown in the dotted line in 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 the pulse width of pwm pulse signal and amplifying PWM rp pulse signal, following situation is limited,, when user U is on walking band 120 during walking, walking band 120 is moved beyond the distance of the driving amount being produced by drive motor 128 towards rear side.
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 in the situation that of driving walking band 120 making drive motor 128 rotation, while having served as in current direction drive motor 128, this overcurrent flows into overcurrent from the source side of thyristor 203b and prevents circuit 208.When preventing that by overcurrent circuit 208 from detecting this overcurrent, overcurrent prevents circuit 208 output Low (=0), this output 0 with from the pwm pulse signal of CPU205 output, adder 209, carried out " with " processing.During due to the signal that is any pulse width at pwm pulse signal, the output of adder 209 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 plays a role constantly.
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.
[the 3rd embodiment]
Next, the walking movement machine 100 the utility model the 3rd embodiment being related to describes.
The walking movement machine 100 of the 3rd embodiment has outward appearance and the frame for movement roughly the same with the walking movement machine 100 of the second embodiment.But the formation of the control part 200 that the walking movement machine 100 of the 3rd embodiment possesses (limiting mechanism 150) is different from the second embodiment.
The block diagram of the limiting mechanism of the 3rd embodiment shown in Fig. 9.
As shown in Figure 9, control part 200 consists of rectification part 201 and PWM control part 202, wherein, rectification part 201 converts the civil power of supplying with from outside (interchange) 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.
Rectification part 201 is by diode 204 bridge joints are formed.
PWM control part 202 has: the thyristor 203 of MOS-FET etc., the pulse width of pwm pulse signal is changed to the CPU205 of desirable width and by the anti-phase phase inverter 206 of this pwm pulse signal.In addition, PWM control part 202 also possesses half-bridge gate driver 207 and overcurrent prevents circuit 208.
And then the control part 200 of the 3rd embodiment has the distribution that the 0V side distribution of the side of the positive electrode distribution of drive motor 128 and drive motor 128 is connected, and, resistance 300 on this distribution, be provided with.The action effect that this resistance 300 is brought into play is as described below.
When user U carries out walking, when the translational speed of walking band 120 departs from certain value when above from setting value, control part 200 carries out work and changes the rotary driving force (being in other words rotating speed) of drive motor 128.
This situation is identical with situation illustrated in the second embodiment,, for example, when becoming walking due to user U and make the translational speed of walking band 120 for example accelerate the situation of (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.Now, 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 thyristor 203a is switched and to make drive motor 128 become short-circuit condition, and, when wanting to make drive motor 128 rotation under this state, palingenesis play a role (generation counter electromotive force) in this drive motor 128.Now, control electric current (stalling current) is mobile as shown in the dotted line in Fig. 9.This palingenesis becomes load for user U, thereby to wanting, the action of walking band 120 fast moving is played a role as brake.The counter electromotive force producing is in this case applied to electronic device, such as thyristor 203 or not shown capacitor etc. of control part 200 inside, even likely damages this electronic device when the worst.
Therefore, in the 3rd embodiment, by the resistance 300 being arranged on drive motor 128, consume the counter electromotive force producing in drive motor 128, thereby can prevent the electronic device of control part 200 inside to bring harmful effect.
In order effectively resistance 300 to be dispelled the heat because of the heat that consumes counter electromotive force and produce, this resistance 300 can be arranged in lower horizontal framework 106 grades of walking movement machine 100, and utilize and undertaken cooling by the wind that is arranged on the generations such as fan on drive motor 128.
In addition, by this resistance 300 is set, the input of drive motor 128 becomes the state (closed circuit with the resistance value R of regulation) that approaches closed (close) state.That is, be not short-circuit condition completely, but be in the state that is short circuit under the intervention of resistance value R of resistance 300.Therefore, by configuring this resistance 300, can continue to produce counter electromotive force to a certain degree, and can answer in contrast ground to realize the braking action to walking band 120.Therefore,, by suitably setting the resistance value R of resistance 300, can not need as shown in figure 10 to arrange thyristor 203a yet, thereby can seek to reduce costs.
And then, the control part 200 of the 3rd embodiment has the distribution that the 0V side distribution of the side of the positive electrode distribution of drive motor 128 and drive motor 128 is connected, and, can utilize relay switch 301 that this distribution is connected to (ON) or disconnects (OFF).The work of this relay switch 301 and the action effect of bringing into play are as described below.
Suppose that user U is just carrying out the situation of walking on walking band 120.Now, suppose that the plug that for example supply power is used comes off suddenly or stops supplying with civil power (power failure).In addition, suppose that safety circuit is carried out work because increase causes fuse to be cut off to the load of drive motor 128.Under these situations, from the block diagram of Fig. 9 clearly: the input of drive motor 128 becomes opens (open) state, and the counter electromotive force working before this thus completely no longer plays a role.In this situation, walking band 120 is idling conditions, thereby hinders user U to carry out safely walking with normal condition.
Therefore, at civil power power-off midway or fuse, be cut off and safety circuit while carrying out work, make relay switch 301 work and the contact of relay switch 301 is connected to A side, thereby making the input of drive motor 128 become closure state.
Particularly, as relay switch 301, adopt " relay switch of power supply linkage type ", when being supplied to civil power, the contact of relay switch 301 is connected to B side and the input that makes drive motor 128 in opened condition.When not supplying with civil power, make relay switch 301 work and the contact of relay switch 301 is connected to A side, thereby making the input of drive motor 128 become closure state.So drive motor 128 is in producing the state of maximum back emf, thereby walking band 120 is and is endowed the state of brake force and has avoided idle running, and user U can stop walking safely thus.
In addition, be especially preferably configured to the signal utilizing from CPU205 and make relay switch 301 work.The in the situation that of this formation, when walking band 120 is when stopping, make relay switch 301 work and the contact of relay switch 301 is connected to A side and makes the input of drive motor 128 become closure state, thereby making drive motor 128 performance braking actions.Then, when walking band 120 starts when mobile a little, the contact of relay switch 301 is connected to B side and the input that makes drive motor 128 in opened condition, thereby brake off effect.By like this, can guarantee that user more safely carries out walking action.
In addition, due to other formations of the 3rd embodiment and the action effect of bringing into play and the second embodiment roughly the same, therefore omit its detailed explanation.
Should think that all aspects of above disclosed embodiment are illustration, rather than restrictive content.Especially about clearly not 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 conventionally, but the value that adopts one of ordinary skill in the art easily to expect.
