Abstract

The utility model relates to an electric running machine. The utility model is characterized in that the relative positions of both sides of a running frame are respectively provided with a speed increasing induction line and a speed decreasing induction line according to the front and rear relationship of a central reference point. After a runner touches a fixed point induction position composed of a light wave or a sound wave, a central processor can immediately emit a speed increasing instruction and a speed decreasing instruction to a motor according to the preset value of the induction position, and thereby, the utility model can generate the function that the rotating speed of a running belt is instantaneously controlled. The utility model can also be provided with a stop induction line behind the speed decreasing induction line. When a runner has the continuous displacement towards the back part of the running machine due to a certain reason and touches the stop induction line, the central processor immediately stops the operation of the motor, and thereby, the safety of the runner is ensured.

Description of drawings

Further deeply know design feature of the present utility model and application means thereof clearly for making, cooperate now that graphic details are as follows:

Fig. 1 is the schematic perspective view of the utility model one preferable use embodiment.

Fig. 2 system is according to the floor map of preferred embodiment shown in Figure 1, in order to explanation line of induction position.

The specific embodiment

Before explanation the utility model feature, in the time of please holding the applicant just the runner carries out road-work on the road-work machine once more, produce some understand in institute must phenomenon do a schematic illustration, uses understanding basic control principle of the present utility model:

One, when the rotating speed of runner's the velocity and the band of running is identical, the runner present position is with constant.

Two, when runner's velocity was higher than the rotating speed of the band of running, the runner present position will be to the displacement of body the place ahead.

Three, when runner's velocity was lower than the rotating speed of the band of running, the runner present position will be to the displacement of body rear.

Therefore, when supposing that runner system stand in body central authorities and carries out road-work, then its velocity is fast, slow, and its residing position will be changed thereupon.

As shown in Figure 1 and Figure 2, this treadmill includes a running frame 10, an armrest part 11, an electronics dash board 12, a motor 13, the basic building blocks such as being with 14 and one rear pole 15 of running, wherein, but motor 13 is with transmission one belt 16, this belt 16 then will drive a front wheel 17, in addition, run be with 14 be circle on forward and backward

roller

17,18, and can because of the transmission of motor 13 constantly wheel change; It is characterized in that:

Its mainly tie up to running frame 10 adjacent to running with 14 both sides, be provided with a multiple according to the forward and backward relation of central reference point respectively successively and increase the even line of induction 20, the one basic speedup line of induction 30 and a deceleration line of induction 40, with convenient runner touch this by the fixed point sensed position that light wave or sound wave were constituted after, central processing unit (being positioned at electronics dash board 12) is just complied with the preset value of this sensed position and is assigned the instruction that increases, slows down immediately and give motor 13, and then produces the effect of instant control running with 14 rotating speeds.

As for, the operation principles and the mode of this each line of

induction

20,30,40, then please cooperate consult shown in Figure 2, it mainly is to send a horizontal straight line signal (being shown in the dotted line) with respect to running frame 10 with

sensing element

21,31,41 (as infrared ray, laser light, radar wave etc.), after wherein a certain line of

induction

20,30,40 signals detected runner's triggering message, central processing unit just carried out automatically immediately and preestablishes motor 13 control instructions.

Thus, when runner's velocity and current running are with 14 rotating speeds to conform to, then this runner's ideal position system is positioned to run and is with 14 centre, and when velocity is higher than current running and is with 14 rotating speeds, then the runner position will be to the displacement of body the place ahead, and then at first touch the basic speedup line of induction 30, certainly, this moment motor 13 will be according to preset value automatic continuous speedup, yet, in case velocity still is higher than the running that continues after the speedup when being with 14 rotating speeds, then the runner will touch the multiple speedup line of induction 20, and make motor 13 continue strengthen its speedup value in moment, and this lasting speedup action will be after the runner no longer touches the multiple speedup line of induction 20 and the basic speedup line of induction 30, the motor 13 sides speedup deliberate action that no longer carries out; Otherwise, when being lower than, velocity runs when being with 14 rotating speeds, then will touch the deceleration line of induction 40 because of the displacement of health, and at this moment, the motor 13 deceleration deliberate action that will carry out immediately and constantly is till the runner no longer touches this deceleration line of induction 40.

In brief, running is general normal movement position (being velocity and the motion state of running and conforming to 14 speed) with 14 middle positions, and relevantly respectively increase, the position that is provided with of the deceleration line of

induction

20,30,40 just is to be datum mark with runner this proper motion position of living in, set respectively according to the forward and backward relative position of this datum mark again.

Separating of aforementioned basic speedup and multiple speedup, it mainly is velocity in response to the runner, that is, when velocity relaxes increase, then motor 13 will cooperate synchronously and relax speedup (being basic speedup), and when the rapid increase of velocity, then motor 13 must cooperate certainly and immediately by high rotational speed (being the multiple speedup) to meet this motion requirement, otherwise the deceleration line of induction 40 is as the same.

Again, the utility model also is able at the rear of the deceleration line of induction 40, establishes one again and stops the line of induction 50, continues to the 10 rear displacements of running frame for some reason and when touching this and stopping the line of induction 50 with convenient runner, central processing unit will stop the running of motor 13 immediately, and then guarantee runner's safety.

In fact, this stops the line of induction 50 (also having sensing element 51) and can be applied to separately on arbitrary treadmill, so that replace existing safety outage latch 19 effects of generally being adopted, certainly, this two safety device (promptly stopping the line of induction 50 and safety outage latch 19) also can be used simultaneously, to obtain the double insurance effect.
