In addition this operating surface,On plate, be provided with and accelerate and retard button toward contact, on some treadmills, be also provided with classification constant speed button,While regulating the speed for sporter. But, no matter be to accelerate and retard button, or classification is fixed, all there is a common problem in speed button. That is, these buttons all need sporter's manual adjustments,For the sporter who has vision disorder or run at a high speed, this manual operation just seems veryInconvenience, sometimes even can initiation potential.
Therefore, this area needs a kind of device that can automatically regulate treadmill speed,This device can automatic decision sporter acceleration and deceleration demand and correspondingly regulate, and notNeed sporter to carry out any manual operation, thereby eliminated manually operated inconvenience and phase with itThe danger of closing.
Summary of the invention
The present invention is intended to address the above problem. Particularly, the present invention is intended to solve existingThere is the problem that treadmill cannot automatic speed regulation. For this purpose, the invention provides one for treadmillAutomatic speed governing device. This automatic speed governing device is characterised in that and comprises: treadmill belt tension detector,It is for detecting in real time sporter's foothold front and the treadmill belt tension force at rear; And motorRotational speed governor, it is communicated with the motor of described treadmill belt tension detector and described treadmill,For control the rotating speed of described motor according to the testing result of described treadmill belt tension detector.Preferably, the treadmill belt in sporter's foothold front detected when described treadmill belt tension detectorWhen difference between the treadmill belt tension force at tension force and sporter's foothold rear reaches certain threshold value,Described motor speed controller is just ordered described motor acceleration or deceleration.
In the situation that adopting technical scheme of the present invention, when sporter is on treadmillRun or when walking, if need to slow down, sporter can Slow Down or at hand steered treadmillReverse pedaling running band forward when handle, now, because sporter's leg speed advanced in years is lower than raceThe speed of service backward of step band, the leg that treadmill belt is pulling sporter to a certain extent moves backward.In this case, if taking sporter's foothold as benchmark, treadmill belt tension detector meetingDetect that the treadmill belt tension force in foothold front is less than the treadmill belt tension force at foothold rear, this showsSporter is intended to reduce the speed of treadmill, and now motor speed controller just can be according to runningThe testing result of belt tension detector directly reduces the rotating speed of motor, and does not need sporter to carry out handMoving operation. Otherwise if need to accelerate, sporter can hasten one's steps or in hand steered runningWhen machine handle, trample backward treadmill belt, now, because sporter's leg speed advanced in years is higher than runningThe transmission speed of band, treadmill belt to a certain extent passive movement person's leg is pulling operation backward. ?In this case, if taking sporter's foothold as benchmark, treadmill belt tension detector can be examinedThe treadmill belt tension force that measures foothold front is greater than the treadmill belt tension force at foothold rear, and this shows fortuneMoving person is intended to improve the speed of treadmill, and now motor speed controller just can be according to treadmill beltThe testing result of tension detector directly improves the rotating speed of motor, and does not need sporter to come manuallyOperation. It is pointed out that no matter be to need to accelerate or slow down, sporter is adding about this pointWhen fast step (backward pedal treadmill belt) or Slow Down (pedaling running band forward) amplitude all withoutNeed be excessive, as long as described treadmill belt tension detector can detect the tension variation of foothold front and back. Otherwise especially, in the situation that slowing down Slow Down because of needs, amplitude is excessive mayCause sporter to drop from treadmill.
In the preferred embodiment of above-mentioned automatic speed governing device, when described treadmill belt is openedForce detector detects that the treadmill belt tension force in sporter's foothold front is greater than the race at foothold rearWhen step belt tension and the difference between the two reach certain threshold value, described motor speed controllerJust order described motor to accelerate, and wherein, when described treadmill belt tension detector detects fortuneThe treadmill belt tension force in moving person's foothold front is less than the treadmill belt tension force at foothold rear and the twoBetween difference while reaching certain threshold value, described motor speed controller is just ordered described motorSlow down.
In the ideal case, in the time that sporter runs or walks on treadmill, it fallsTreadmill belt tension force before and after pin point should be roughly equal. Therefore, if the inspection of treadmill belt tension detectorThe treadmill belt tension force measuring before foothold is greater than the treadmill belt tension force after foothold, shows sporterIntention is accelerated; Otherwise, if the treadmill belt that the treadmill belt tension force before foothold is less than after foothold is openedPower, shows that sporter is intended to slow down. But, due to each sporter's individual difference, stop overTension Difference before and after point may be different. Therefore, for each sporter, above-mentioned threshold valueAlso may be different. For example, for some sporter, it likes being dragged by treadmill belt at ordinary timesDragging and running or walking, the treadmill belt tension force before its foothold is less than after foothold under normal circumstancesTreadmill belt tension force, even because want to accelerate while hastening one's steps, the treadmill belt before its footholdTension force may also be slightly less than the treadmill belt tension force after foothold. In this case, for this fortuneMoving person, threshold value when above-mentioned acceleration is exactly negative value. Certainly, this special circumstances can be passed throughSetting parameter device of the present invention solves, and specifically refers to detailed description below.
In the preferred embodiment of above-mentioned automatic speed governing device, described treadmill belt tension forceDetector comprises multiple treadmill belt tension pick-ups, described in described treadmill belt tension pick-up is arranged onOn the main frame of treadmill, or be arranged on front and back housing described treadmill, close treadmill beltUpper, or be arranged on described treadmill belt, or be arranged on the running board of described treadmill belt below,For detection of the treadmill belt tension force at sporter's foothold front and rear. When described treadmill belt tension forceSensor setting is on treadmill belt time, and it preferably adopts contact tension pick-up. When described raceStep belt tension sensor setting is on described main frame, housing or running board time, and it preferably adoptsNon-contact tension sensor. These sensors can arrange on comparatively dense ground, to cover treadmill beltEach position, thereby which position of sporter's foothold on treadmill belt no matter, described biographySensor can detect the treadmill belt tension force of sporter's foothold front and back exactly.
In the preferred embodiment of above-mentioned automatic speed governing device, this treadmill comprises masterFramework, described motor, driven roller, driven voller, described running board and described treadmill belt, this is mainFramework comprises column and horizontal stand, and described motor and driven roller are arranged on the level of this main frameOne end of support, described motor is connected with driven roller and for it provides power, driven voller and drivingRoller is arranged on the other end of horizontal stand opposed to each other, and described running board is between driven roller and driven vollerExtend and between two siding tracks of horizontal stand, described treadmill belt is wound around driven roller and drivenRoller and being laid on described running board. Preferably, this treadmill also comprises two pairs of bearings, and this is mainFramework also comprises two pairs of bearing blocks that are arranged on described horizontal stand, described driven roller and driven vollerBe connected on described main frame by described two pairs of bearings and bearing block respectively, wherein, described runningBelt tension detector comprises multiple pressure sensors, described pressure sensor be arranged on described bearing withBetween bearing block and be positioned at the side near running board central authorities, and wherein, when described driven rollerBearing and bearing block between the pressure that detects of pressure sensor be greater than the bearing of described driven vollerBe greater than necessarily with the pressure that the pressure sensor between bearing block detects and the difference between the twoWhen threshold value, described motor speed controller just orders described motor to accelerate; And drive described in working asThe pressure that pressure sensor between bearing and the bearing block of action roller detects is less than described driven vollerThe pressure that pressure sensor between bearing and bearing block detects and the difference between the two are greater thanWhen certain threshold value, described motor speed controller is just ordered described motor deceleration.
Those skilled in the art hold intelligible, and the tension force of treadmill belt can directly be examinedSurvey, the active force that also can be applied on driven roller or driven voller by treadmill belt detects.
