Abstract

A variable speed backfeed device of a treadmill mainly relates to a turning shaft of the treadmill rotation gear connected with a grating tray, the rotate speeds of the grating tray and the turning shaft are induced by fluctuant frequency of a penetrating area and a shading area ring arranged on the near parietal surface of the grating tray due to a light source laser, and the grating tray is connected with an inductive chip with set value of rotate speed, and differential value between the actual rotate speed and the set value of rotate speed are line connected and transmitted to a computer, the computer is connected with a motor driver by a backfeed path to make the speed of the cyclic running tape dragged by the speed of the runner (in particularly to accelerating) become the rotate speed which is suitable for the runner.

Description

Treadmill speed change feedback device

Technical field

The utility model relates to a kind of treadmill speed change (referring to especially quicken) feedback device, refer in particular to the rate value that a kind of runner of utilization and treadmill originally set, produce the change difference, setting value is changed at any time, with the friction of runner's step circulation is run and be with a kind of device of the speed convergence that produces.

Background technology

Therefore run useful blood vessel and cardio-pulmonary function become the mode of many people's health cares, motion.Modern society is because the required place of running is difficult for seeking, so treadmill receives an acclaim, and not only saves the required athletic ground of running, and is convenient to the user and anytime anywhere all can makes road-work.

The structure of existing treadmill mainly includes outside frame and body, and this outside frame is provided with handrail and can grips with stable for the runner.Body mainly comprises a rotating mechanism, and rotating mechanism outer rim ring set is provided with the running tape loop, and the person that more do not make progress with the running tape loop of motor driving treadmill, reaches and forces the runner to try to move for running with setting, has to overcome the idle function of human nature.This treadmill, its running tape loop are with the institute of the turning cylinder in rotating mechanism interlock.The rotating speed of turning cylinder is to utilize computer to set a fixed rotating speed value by the user, and motor driver makes motor running with this rotating speed.Yet runner's running speed is not constant speed.The treadmill of being developed at present can't be adjusted at any time with the required rotating speed of runner.

Also has a kind of safety type treadmill, be to establish an electric eye, can't catch up with setting speed, when falling behind in running tape loop proximal end position when runner's running speed in running tape loop proximal end two side optional positions, the electric eye detecting is that line makes starting switch suspend, and avoids the runner to fall down.But this safety type electric eye structure when only limiting to runner's speed slowly to a certain degree, just starts and suspends, and is a kind of safeguard protection of passiveness.For more making great efforts the runner, can't present the function of its acceleration once.

Summary of the invention

The purpose of this utility model is, provide a kind of can be with the treadmill of the in good time speed change of runner's speed, i.e. treadmill speed change (referring to especially quicken) feedback device makes the rotating speed of treadmill accelerate and regulate at any time with user's running velocity.

Major technique content of the present utility model is: be to be connected with a grating dish on the turning cylinder of original treadmill, utilize light irradiation device irradiation grating dish and respond to the rotating speed of grating dish and turning cylinder, light irradiation device connects an induction wafer, the induction wafer is transmitted to computer with the rotating speed difference line of actual speed and former setting, and computer links to each other with motor driver with feedback path.This difference of computer computing answers the velocity information of feedback, motor driver to make motor rotary speed change in the rotating mechanism.Become the speed that is suitable for the runner with the speed that is dragged circulation running band with runner's speed.Make the rotating speed of treadmill can timely adjustment with user's faster rotational speed.

The specific embodiment

Below in conjunction with description of drawings structure of the present utility model, characteristics and embodiment.

See also Fig. 1, the utility model is a kind of treadmill speed change (referring to especially quicken) feedback device.This treadmill mainly includes outside frame 1 and body 2, and handrail 11 has been set up in this outside.Body 2 comprises a launch computer mechanism 21 (its circuit design is a prior art), rotating mechanism 22 and tilt adjusting mechanism 23, the turning cylinder 221 outer rim ring sets of rotating mechanism are provided with running tape loop 24, and can be in the terminal either side of running tape loop, an if electric eye device 25, with closing of line launch computer mechanism, when user's speed too falls behind, the induction of electric eye device, line launch computer mechanism shuts down body, to safeguard user's safety.

Figure 2 shows that speed change (acceleration) device of this creation, be that turning cylinder 221 in the rotating mechanism 22 of treadmill is connected with a grating dish 3, the nearly periphery in the surface of this grating dish 3, a secondary ring is established most penetrating regions 31 and shielded area 32, and in the limit of facing of grating panel surface one light irradiation device 4 is set.The nearly peripheries in the light source of this light irradiation device 4 corresponding grating dish 3 surfaces are by the transmission and the variation frequency of reflection that light is penetrated and penetrating region 31 and shielded area 32 are produced, to respond to grating dish 3 rotating speeds.And these light irradiation device 4 connections one have the induction wafer 5 of speed setting value, and with runner's step friction running tape loop 24, and forced speed for what turning cylinder 221 produced, form a difference with the setting value computing, and difference signal line is transmitted to launch computer mechanism 21, this difference of computer computing, and link to each other with the motor driver 222 of rotating mechanism 22 with another line, answer the speed message of feedback, motor driver makes the motor 223 rotating speeds changes (accelerated service) in the rotating mechanism.

Shown in Figure 3, the enforcement of this creation needs to cooperate earlier induction wafer 5 be transfused to a setting value (expression constant speed), and originally motor driver 222 makes motor 223 in the rotating mechanism according to constant speed drive.

Catch up with constant speed and work as the runner, runner's step friction running tape loop 24, must produce the bigger speed of forcing for turning cylinder, and find expression in the rotating speed of grating dish 3, after light irradiation device 4 irradiations this moment, see through induction wafer 5 with the bigger change value of forcing speed of this representative, form a difference with former setting value computing, and difference signal line is transmitted to launch computer mechanism 21, the speed message of feedback is answered by launch computer mechanism, link to each other with motor driver with another line, and make motor 223 rotating speeds changes (accelerated service).

This creation utilizes the friction of runner's step and circulation is run when being with the speed that produces, the turning cylinder that utilization running band is connected is interlock in the lump, the rate value that originally set with treadmill produces the change difference, utilize feedback device, feasible setting value changes at any time, with runner's step friction and circulation is run speed convergence that band produces, makes the treadmill can more humane, the in good time reaction rate of motorization, and be a feedback, more practical for the runner.

Above-mentioned institute is old to be a preferred embodiment on this creation industry, and the equalization of doing according to present patent application changes such as, all belongs to this case and contains.
