Description

Control method of exercise equipment {CONTROLLING METHOD FOR AN EXERCISE EQUIPMENT}

The present invention relates to an exercise machine, and more specifically, to a control method of an exercise machine for controlling the load of the wire being drawn/drawn in in the exercise machine where the user climbs on the seating surface of the main body and draws/draws the wire.

Generally, exercise equipment used for strength training is designed to repeat muscle relaxation and contraction by pushing or pulling a lever connected to a weight having a certain unit of weight.

Among these exercise devices, there are a variety of exercise devices, such as arm curl machines for bicep exercises, chest press or butterfly machines for chest exercises such as the pectoralis major, and pull up machines for muscle exercises. Exercise equipment exists.

Recently, home training, which involves exercising alone at home without visiting a fitness center, has become popular as a form of self-management, and in line with this trend, various exercise devices for home training are being proposed.

Among the exercise devices for home training, there are exercise devices that allow the user to exercise while standing up on the exercise device, for example, a mat-type exercise device. In the case of such a mat-type exercise device, a handle is connected to a wire exposed to the outside of the main body, and the user exercises by repeatedly pulling the handle.

Such exercise devices enable exercise by actively applying resistance equal to the external force applied by the user, in accordance with the target load set by the user. In other words, the exercise device generates and provides a virtual output load in accordance with the target load set by the user, and the driving unit composed of a drive motor is generally configured to feed back the output load based on the position information of the exercise device.

Unlike general rehabilitation exercise equipment, exercise equipment for home training generates an output load using a high-output driving unit due to the nature of exercise.

Exercise equipment has its own dynamic characteristics, such as a high-output driving unit and a driving force transmission unit for transmitting the output of the driving unit to the user. Therefore, due to the dynamic characteristics of the exercise device itself, the output load (or control input value) of the driving unit always generates a constant exercise load regardless of the user's intention.

In addition, recently, among exercise tools for home training, exercise methods using elastic bands have been widely used. Elastic bands include tubing bands and latex bands that have high elasticity and do not tear easily.

These elastic bands apply different loads depending on the tension length, so that the user who uses the elastic band tenses the muscles in the area at the beginning of the tension, and the tense muscles prevent the joints from bending and twisting, thereby preventing injury to the user. You can.

In other words, in the case of exercise equipment for home training, there is no choice but to always exercise using the same exercise load, and the muscle is relaxed through excessive load from the beginning without a relaxation process after the user's muscle tension, so excessive exercise load during exercise is avoided. There is a problem that may result in a risk of injury.

The present invention was made to solve the above problems, and the purpose of the present invention is to provide a control method for an exercise device using a wire that applies a variable exercise load depending on the withdrawal/retraction length of the wire. .

Here, the control unit 8 waits for the input of the user's exercise conditions (basic load (kg) and elastic load (K)) as the exercise machine starts operating, and operates the power unit 27 and the load according to the user's exercise conditions. By controlling the generator 2, the load applied to the wire 24 can be varied according to the user's withdrawal/input of the wire 24. Therefore, users can achieve the same exercise effect as using an elastic band.

Here, the power unit 27 varies the current supplied to the stator 21 of the load generators 21 and 23 according to the basic load (kg) and elastic load (K) conditions set through the input unit 71 to generate the stator 21. ), the exercise load (kgf) applied to the wire 24 can be varied.

Accordingly, the operation of the exercise machine according to one embodiment of the present invention will be described in detail through examples. Each element mentioned below should be understood with reference to the above description and drawings.

Figure 5 is a flowchart showing the control process of the exercise machine according to an embodiment of the present invention, and Figure 6 is a graph showing the elastic load setting of the exercise machine according to an embodiment of the present invention.

Meanwhile, before using the exercise device 100, the user determines the basic load (kg) and elastic load (K) for operation of the exercise device 100 and sets the basic load (kg) and elastic load (K) to the exercise device 100. You can perform exercise using the exercise device 100 by inputting it into (100).

Here, the input of the basic load (kg) and elastic load (K) of the exercise device 100 is input through the input unit 71 provided on the exercise device 100 or a communication device connected to the exercise device 100 and the communication interface 81. It can be input through the device 200.

The basic load (kg) and elastic load (K) may be input according to the user's selection, and there may be various other embodiments. Therefore, the input unit 71 and the communication device 200 do not limit the embodiment of the present invention, and the exercise device 100 can input the basic load (kg) and elastic load (K) to perform exercise. In this case, it should be said to be included in the technical scope of the present invention.

Additionally, the user will be able to exercise by selectively inputting the basic load (kg) or the basic load (kg) and elastic load (K).

That is, when the user inputs only the basic load (kg) and performs exercise using the exercise device 100, the control unit 8 controls the power unit 27 to determine the correlation with the withdrawal/input length (X) of the wire 24. Without this, the current value applied to the stator 21 of the load generators 21 and 23 can be supplied at a constant level.

Therefore, the load generators 21 and 23 always form the same load regardless of the lead-in/out length (X) of the wire 24, and the user always creates the same load regardless of the lead-out/in-out length (X) of the wire 24. Exercises can also be performed with an exercise load (kgf). In other words, when exercising using only the basic load (kg), the input basic load (kg) can be considered the same as the exercise load (kgf) generated by the load generators 21 and 23.

Alternatively, when the user inputs both the basic load (kg) and the elastic load (K) and performs an exercise using the exercise device 100, the control unit 8 controls the elastic load (K) in addition to the basic load (kg). The current value applied to the stator 21 of the load generators 21 and 23 can be varied and supplied in response to the lead-out/in-out length (X) of the wire 24.

Therefore, the load generators 21 and 23 form a load that increases or decreases in response to the elastic load (K) according to the withdrawal/input length (X) of the wire 24, and the user controls the withdrawal/input length (X) of the wire 24 Depending on X), the exercise may be performed with the same exercise load (kgf) as using an elastic band.

As shown in FIG. 5, the control method of the exercise machine 100 according to an embodiment of the present invention includes load setting steps (S110, S120) for setting the load of the exercise machine 100, and drawing out the wire 24. /wire detection step (S130, S140) that detects the lead-in and draw-in/draw-in length (X) and the load generator (21, 23) by controlling the power supply unit 27 according to the load set according to the lead-in/draw-out length (X) of the wire 24 A load control step (S150, S160) to control the exercise load (kgf) generated in the exercise judgment step (S170, S180) to determine whether to use the exercise device 100 according to the withdrawal/input of the wire 24. It can be included.

Here, the load setting step (S110, S120) is a basic load setting step (S110) that sets the basic load (kg), which is the standard for the elastic load (K), and the drawing of the wire 24 based on the basic load (kg). /It may include an elastic load setting step (S120) of setting the elastic load (K) to vary the load according to the pull-in.

The basic load setting step (S110) may be set according to the user's input as the exercise device 100 begins to operate. The user can input the basic load (kg) through the input unit 71 or the communication device 200 provided in the exercise device 100. Here, the basic load (kg) can be entered as a unit representing weight, or as a numerical value arbitrarily divided according to weight.

Here, the basic load setting step (S110) is a value that becomes the standard for the elastic load (K) to be set by the user later, and sets the load that can be basically applied when the user withdraws/retracts the wire 24. In other words, it can be said that the load is basically applied to the load generators 21 and 23 around which the wire 24 is wound during the process of first pulling out the wire 24 when the user uses the exercise device 100.

The elastic load setting step (S120) is for inputting an elastic load (K) to vary the load of the load generators (21, 23) according to the withdrawal/retraction of the wire after the basic load setting step (S110). This elastic load setting step (S120) can be set according to the user's input after inputting the basic load (kg). The user can input the elastic load (K) through the input unit 71 provided in the exercise device 100 or the communication device 200. Here, the elastic load (K) can be entered as a unit representing the elastic modulus or as an arbitrarily divided value.

Here, the elastic load setting step (S120) increases the load generated from the load generators (21, 23) according to the drawn-out length of the wire with respect to the basic load (kg) set in the basic load setting step (S110). This is to reduce the load generated from the load generators (21, 23) depending on the lead-in length of the wire. Here, in the case of elastic load (K), functions of various conditions can be applied as an increase/decrease function for the basic load (kg).

Specifically, the control unit 8 generates a load generator ( The current supplied to the stator 21 of 21, 23) can be increased/decreased depending on the withdrawal/input of the wire.

That is, the control process of the load generators 21 and 23 by the control unit 8 may appear as in the graph shown in FIG. 6. As shown, the load at which the exercise load (kgf) starts can be set according to the basic load (kg) input in the basic load setting step (S110). In addition, the exercise load (kgf) can be increased/decreased proportionally according to the elastic load (K) from the load where the exercise load (kgf) starts according to the elastic load (K) input in the elastic load setting step (S120). there is.

Additionally, this increase in exercise load (kgf) may vary depending on the conditions of the elastic load (K), the withdrawal/input of the wire 24, and the elastic load (K). That is, the exercise load (kgf) set by the basic load (kg) and the elastic load (K) may increase or decrease depending on the lead-out/retract length (X) of the wire 24 in addition to the elastic load (K).

Meanwhile, the wire detection step (S130, S140) includes a withdrawal detection step (S130) that detects that the user starts to withdraw the wire 24, and a withdrawal/retraction length (X) of the wire 24. It may include a length change detection step (S140).

The withdrawal detection step (S130) detects that the first wire is pulled out when the user uses the exercise device 100, and controls the load of the load generators 21 and 23 in the load control steps (S150 and S160) to be described later. It can be applied as a variable for

Here, in the withdrawal detection step (S130), as the user pulls the wire 24, the wire 24 wound around the load generators 21 and 23 is unwound and moves along the wire guide 3. At this time, it can be detected that the wire 24 is pulled out from the encoder 262 as the gear 261 meshed with the rotor gear 263 provided on the rotor 23 of the load generators 21 and 23 rotates. In this withdrawal detection step (S130), it can be determined that the user has actually started exercising by using the withdrawal of the wire 24.

In the length change detection step (S140), as the encoder 262 detects the withdrawal of the wire 24, the withdrawal/retraction length (X) of the wire 24 according to the withdrawal of the wire 24 can be detected. The withdrawal/input length ( It can be applied as.

Meanwhile, in the load control step (S150 and S160), the power supply unit 27 supplies the stator 21 of the load generators 21 and 23 according to the withdrawal/input of the wire detected in the length change detection step S140. This is to vary the exercise load (kgf) of the wire 24 by the load generators 21 and 23 by varying the current.

These load control steps (S150, S160) control the power unit 27 according to the withdrawal/input length (X) of the wire detected in the length change detection step (S140) of the wire 24 to load generators 21 and 23. ), a power variable step (S150) that increases and decreases the current supplied to the stator (21), and a load control step (S160) in which the load generators (21, 23) are controlled according to the power supplied in the power variable step (S150). ) may include.

The power variable step (S150) includes the basic load (kg) input in the basic load setting step (S110), the elastic load (K) input in the elastic load setting step (S120), and the length change detection step (S140). The current supplied from the power supply unit 27 to the stator 21 varies according to the change in the length of the wire 24 detected.

In the load control step (S150, S160), a rotating magnetic field is generated in the stator 21 of the load generators 21 and 23 according to the current of the power supply 27 controlled in the power variable step (S150), and the stator 21 ) A load is applied to the rotation of the rotor 23 by the rotating magnetic field.

Here, the rotating magnetic field acting on the rotor 23 by the stator 21 is varied according to the control of the power supply unit 27 in the power variable step (S150), and is applied as a kinetic load to the withdrawal/input of the wire wound on the rotor. It can work.

That is, the control unit 8 operates in the load generators 21 and 23 as the drawn-out length of the wire 24 increases according to the drawn-out/drawn-out length (X) of the wire 24 detected in the length change detection step (S140). The load generated from the load generators 21 and 23 can be proportionally increased, and alternatively, the load generated from the load generators 21 and 23 can be proportionally reduced as the lead-in length of the wire 24 detected in the length change detection step (S140) decreases. You can.

Therefore, the user can exercise using the exercise device through the process of withdrawing/retracting the wire 24, and the power supplied from the power supply unit 27 to the load generator according to the withdrawal/retraction length (X) of the wire 24 When the current is varied and the exercise load (kgf) increases/decreases in the load generators 21 and 23, an exercise effect similar to that of an elastic band can be obtained.

Meanwhile, in the exercise determination steps (S170, S180), it is determined that the wire 24 is switched from the withdrawal process to the retraction process as the user proceeds with the movement through the withdrawal/retraction of the wire 24. This is to control the load generators 21 and 23 when switching from withdrawal to withdrawal, and to determine whether the user has finished using the exercise device 100.

These exercise determination steps (S170, S180) include a wire detection step (S170) that determines that the wire 24 is switched from withdrawal to retraction (or from retraction to withdrawal), and an exercise end judgment that determines the end of the user's exercise. It may include step S180.

The wire detection step (S170) changes the load control of the load generators 21 and 23 by detecting the user pulling in (or pulling out) the wire while using the exercise device. You can.

That is, in the wire detection step (S170), when the user switches from drawing out to drawing in the wire (or from drawing in to drawing out), the above-described length change detection step (S140) is performed again to generate a load according to the increase or decrease in the change in the length of the wire. The exercise load generated in the area can be proportionally increased/decreased.

For example, the control unit 8 operates the load generators 21 and 23 when the withdrawal/input length (X) of the wire 24 detected in the length change detection step (S140) increases after the wire detection step (S170). The load generated from can be increased in proportion to the increase in the lead-out/in-out length (X) of the wire 24. In addition, the control unit 8 generates a signal in the load generators 21 and 23 when the withdrawal/input length (X) of the wire 24 detected in the length change detection step (S140) after the wire detection step (S170) decreases. The load can be increased in proportion to the decrease in the lead-in/out length (X) of the wire 24.

In the length change detection step (S140), as the encoder 262 detects the withdrawal of the wire 24, the withdrawal/retraction length (X) of the wire 24 according to the withdrawal of the wire 24 can be detected. The withdrawal/input length ( It can be applied as.
