The wire part 200 is directly or indirectly connected to the gripping part 100, and the driving part 300 including the electric motor and the speed reducer may apply a force to the wire 200 to apply a load to the gripping part 100. have.

Although the gripping portion 100 is illustrated as having a bar shape in FIG. 1, the gripping portion 100 may be implemented in the form of a ring, a handle, a strap, or the like, depending on the exercise method used. Of course.

As shown in Figure 1, some of the components of the electric strength training apparatus according to an embodiment of the present invention can be accommodated in the casing 600, the casing 600 is fixed in a desired position to force the user during exercise It may be configured not to move even if applied.

The wire 200 may extend through a predetermined through hole 601 formed in the casing 600. As in the embodiment illustrated in FIG. 5, the casing 600 may be disposed in various orientations, so that one or more through holes 601 and 602 may be formed in the casing 600. In some cases, unused through-holes may be closed. The through hole 601 should be formed with an inner diameter more than the outer diameter of the wire 200.

The wire 200 extends from the casing 600 and is connected to the gripping portion 100 along a desired direction by a series of pulleys 210. As in the embodiment illustrated in FIG. 1, the wire 200 may be connected to the gripping part 100 through the hollow tunnel parts 110 and 120. The first tunnel part 110 formed of a material such as metal may be connected to the grip part 100 and slidably coupled to the second tunnel part 120, and the first tunnel part 110 and the second tunnel may be coupled to each other. The wire 200 may move in an empty space inside the part 120. The configuration of the tunnel parts 110 and 120 may be used to arrange the grip part 100 at a location convenient for a user to use.

The casing 600 may also be provided with means for various types of input and / or output, such as the power button 510 and the touch display 520. The user can prepare for the operation of the muscle exercise equipment by pressing the power button 510, and adjust the load to be used during the exercise, various settings during the operation through the touch display 520, and can check various statistics according to the exercise time have.

Figure 2 is a perspective view showing a driver module of the electric muscle exercise apparatus according to an embodiment of the present invention. As shown in FIG. 2, the driver module 650 of the electric muscular exercise device according to the embodiment of the present invention includes a driving unit 300, a winch drum 350, a tension sensor unit 400, a control unit 500 and The power supply unit 700 may include a power line 750 connected to the power supply unit 700 and a wire 200 having the other end coupled to the winch drum 350 to penetrate from the inside of the driver module 650 to the outside. have.

As described above, the wire 200 is a component that transmits the force of the driving unit 300 to the gripper 100, and may be implemented as a steel wire. One end of the wire 200 may be connected to the grip part 100, and the other end may be wound and coupled to the winch drum 350. For example, the other end of the wire 200 may be fixed at a predetermined point on the winch drum 350, and in this state, the winch drum 350 may be rotated several times so that the wire 200 is at the other end side of the wire 200. A portion of the can be wound around the winch drum 350.

The winch drum 350 may be connected to the driving unit 300 or extend as part of the driving unit 300 to serve as a winch for winding the other end of the wire 200.

When the driving unit 300 applies torque in the direction in which the winch drum 350 winds the wire 200 in the state in which the wire 200 is taut, the tension applied to the wire 200 will increase, and thus the holding unit 100 will be increased. ), The more weight will be applied to the user exercising with. On the contrary, when the torque in the direction in which the winch drum 350 winds the wire 200 is reduced, the tension applied to the wire 200 will be reduced and thus lighter to the user exercising using the gripper 100. The load will be applied.

The driving unit 300 may include an electric motor and a speed reducer. The reducer serves to convert the rotational force of the electric motor into the rotational output of the desired rotational speed or torque. For example, the electric motor can provide a relatively high rotational torque, by coupling a gear having a different rotation ratio to the shaft of the electric motor to convert to a rotation of another rotational speed or torque. In embodiments of the present invention, it may be required for the driving unit 300 to provide a rotation of a high torque rather than a high rotational speed, and for this, an electric motor and a reducer of appropriate performance may be selected.

The tension sensor unit 400 serves to measure the tension of the wire 200 in contact with a predetermined point on the wire 200. The tension sensor unit 400 will be described in more detail later with reference to FIGS. 3 and 4.

The controller 500 may control the operation of the driving unit 300 such that the tension of the wire 200 measured by the tension sensor unit 400 matches a predetermined load. Depending on the function to be performed, the controller 500 may be implemented in a very simple form or in a complex form including a digital processing device.

The controller 500 may be connected to an input unit and an output unit. The input unit may be used to receive predetermined input information from the user. For example, the load to be applied to the holding unit 100, the number of reps, the number of sets, the exercise time, the target calorie consumption, etc. may be input. Can be. The output unit may be used to provide the user with predetermined output information, for example, the load currently applied to the holding unit 100, the current level, the current set number, the model exercise posture, the exercise time, the exercise history, and the present. Calorie consumption, other user's exercise statistics, etc. may be output in the form of guide letters, pictures, charts, videos, voice messages.

The number of reps and the number of sets referred to in the present specification are terms used to express the number of times of exercise as commonly used in the field of strength training. Rep (repetition) is a term that refers to the number of repetition of the exercise, and refers to the process of exercise until the force is returned to its original position once. A set refers to the course of movement from the first to the last reps for a given number of reps. For example, if you perform 3 sets of 10 reps, squats are repeated 10 times without rest, followed by a break of about 1 minute, and 10 more squats in each of the two sets in the same manner.

The input unit may have various forms such as a dial, a switch, a button, a keypad, a touch pad, and a touch display. In addition, as a communication module for communicating with other devices in a wired or wireless manner, a device receiving information from another device will be included in the range of the input unit. For example, the input unit according to an embodiment of the present invention may be connected to a user's smartphone by short-range communication or the like, and may receive various exercise programs through an app installed in the smartphone.

The output unit may be implemented in various forms such as a display, a touch display, an acoustic speaker, and provide the output information to the user visually and / or audibly. The output unit may also be implemented as a device for providing information to other devices. For example, in addition to visually outputting information on the current exercise state to the user, the output unit according to an embodiment of the present invention may transmit and store the exercise record to a server in a remote location, and the like to be stored and managed.

In the embodiment illustrated in FIG. 1, the input unit and the output unit are integrated in the form of the touch display 520, but the input unit and the output unit may be implemented in various forms as described above.

On the other hand, unlike the conventional exercise method using a weight, in the electric strength exercise device according to an embodiment of the present invention does not need to be fixed to the load used by the user for exercise. For example, if a user exercises using a barbell with a weight of 20 kg according to a conventional exercise method, the user generally works with a barbell with the same weight of 20 kg throughout the set. There is a hassle to change to a barbell with a different weight.

On the contrary, in the case of using the electric strength exercise device according to an embodiment of the present invention, the load applied to the gripper 100 is changed by the drive unit 300 under the control of the control unit 500, so that the user exercise It is possible to change the load during the process.

For example, the user may input a predetermined exercise program through the input unit to change the load to 10 kg up to the third level of the set, 15 kg for the next 5 levels, and 12 kg for the last 2 levels. As another example, the user may input a setting related to the squat exercise so that the load may be changed so that a load of 10 kg is applied when the user sits down and a load of 20 kg is applied when it occurs.

As such, according to one embodiment of the present invention, instead of setting a predetermined load as a fixed constant, it may be set as a function according to time, thereby changing the load in one set, and even in one level. It is possible to do

As described above, the control unit 500 operates the driving unit 300 such that the tension of the wire 200 measured by the tension sensor unit 400 matches a predetermined load, that is, the driving unit 300 is the winch drum 350. ) And the tension applied to the wire 200 can be controlled. This will be described in more detail later with reference to FIGS. 6 to 8.

The power supply unit 700 may receive power from the outside through the power line 750 and supply the power to the driving unit 300, the tension sensor unit 400, and the control unit 500. Of course, the power supply 700 is not necessarily to be implemented as a separate component, and may be integrally included in each component according to the needs of the driving unit 300, the tension sensor unit 400, and the control unit 500.

3 is a perspective view showing a tension sensor unit of the electric muscle exercise apparatus according to an embodiment of the present invention, Figure 4 is a side view showing the tension sensor unit of the electric muscle exercise apparatus according to an embodiment of the present invention.

3 and 4, the tension sensor unit 400 according to an embodiment of the present invention has two outer pulleys 410 and two outer pulleys 410 arranged along the traveling direction of the wire 200. It may include one inner pulley 420 disposed between the (). One side of the inner pulley 420 may be provided with a sensor 430 for sensing a pressure, such as a load cell, so that the wire 200 across the inner pulley 420 and the outer pulley 410 to press each other Can be arranged.

When the driving unit 300 applies torque in the direction in which the winch drum 350 winds the wire 200 in the state in which the wire 200 is taut, the tension applied to the wire 200 will increase, and thus the holding unit 100 will be increased. ), The more weight will be applied to the user exercising with. On the contrary, when the torque in the direction in which the winch drum 350 winds the wire 200 is reduced, the tension applied to the wire 200 will be reduced and thus lighter to the user exercising using the gripper 100. The load will be applied.

In the embodiment shown in FIG. 4, the inner pulley 420 is disposed at the exact center between the two outer pulleys 410, and the direction in which the wire 200 presses the inner pulley 420 is the two outer pulleys 410. Orthogonal to the imaginary straight line connecting them. If the tension applied to the wire 200 is T and the angle between the upper surface of the inner pulley 410 and the wire 200 is θ in FIG. 4, the force applied to the inner pulley 410 by a simple static calculation is ( 2T * sin θ), and the tension of the wire 200 can be obtained by calculating this with respect to T.

Of course, the inner pulley 410 does not necessarily have to be disposed at the center of the center between the outer pulleys 420 or in the orthogonal direction, and it is possible to obtain a tension T of the wire 200 by performing a static calculation on the angle. Can be.

Comparing (a) and (b) of Figure 5, the casing 600 may be mounted to the frame 800 in the correct position, or may be mounted upside down inverted. In addition, when the casing 600 is provided with a plurality of through holes 601 and 602 through which the wire 200 passes, the through hole 601 through which the wire 200 passes according to various arrangements of the casing 600. , 602 may be different.

In the casing 600, a series of pulleys may be provided to allow the wires 200 to align and penetrate through the plurality of through holes 601 and 602, respectively. Alternatively, as shown in FIG. 2, components such as the winch drum 350 and the driver 300 may be included in one driver module 650, and the casing 600 may include a plurality of through holes 601 and 602. Couplings (not shown) may be included to secure the driver module 650 in a particular arrangement and orientation so that the wires 200 are aligned and penetrating for each of the plurality of wires.

Referring to FIG. 5B, the frame 800 may include various parts that allow the user to conveniently move. For example, as shown in FIG. 5B, the frame 800 may include a foot support 810, a chair 820, and the like so that the user may perform a rowing motion. Of course, components such as the support 810 may be provided in the casing 600.

FIG. 5C shows an embodiment of the arrangement for the user to do a squat exercise. In the embodiment shown in FIG. 1 two wires extend from one casing 600, while in the embodiment shown in FIG. 5C the wires 200 extend one by one from the two casing 600. . In the case of FIG. 1, the driving unit 300, the tension sensor unit 400, and the control unit 500 are each included one by one, whereas in FIG. 5C, these components are provided for each wire 200. have. As a result, the user can analyze whether the body balances right and left during exercise, and can acquire data for posture correction.

Hereinafter, a method of controlling the electric strength exercise device by controlling the tension of the wire 200 by the control unit 500 of the electric strength exercise device according to an embodiment of the present invention will be described in more detail.

Figure 6 is a flow chart showing a control method of the electric muscle exercise apparatus according to an embodiment of the present invention.

First, a load for the user's exercise may be set in the electric strength exercise apparatus according to the embodiment of the present invention (S900). This process may be a process in which a user inputs a load through another device such as a touch display 520 or a smartphone provided in the exercise equipment, or may be a process of selecting a specific specific load value by using a dial or the like. It may also be the process of setting the load value used for general purpose to the default value.

The control unit 500 of the muscular exercise device may measure the tension of the wire 200 (S910), and determine whether the tension of the wire 200 is equal to the set load (S960).

If the tension of the wire 200 is equal to the set load, the current state may be maintained. Herein, the tension of the wire 200 equal to the predetermined load includes not only the case where the numerical value is exactly the same but also the case where the tension is within a predetermined error range from the set load.

If the tension of the wire 200 is not equal to the set load, the control unit 500 may determine whether the tension of the wire 200 is greater or smaller than the set load (S970), and the tension is greater than the set load. In this case, the driving unit 300 may reduce the torque applied to the wire 200 (S980), and when the tension is smaller than the set load, the driving unit 300 may increase the torque applied to the wire 200 (S990).

7 is a flow chart showing a control method of the electric muscle exercise apparatus according to another embodiment of the present invention.

Setting the load of this embodiment (S900), measuring the tension of the wire 200 (S910) and adjusting the torque of the drive unit 300 so that the tension of the wire 200 is substantially the same as the set load. S960 to S990 may be similar to the steps of the control method described with reference to FIG. 6, and redundant descriptions thereof will be omitted.

After measuring the tension of the wire 200 (S910), the controller 500 may determine whether the tension of the wire 200 is greater than a predetermined upper threshold value (S920). This step may be prepared in the case where abnormally excessive tension is applied to the wire 200, and the upper threshold may be set to an appropriate value accordingly. When excessive tension is applied to the wire 200, it may be evidence of a malfunction of the device, and may cause a situation that may cause damage to the exercise equipment or the user. Therefore, the tension of the wire 200 is greater than the upper threshold. If it is determined that the control unit 500 stops the operation of the drive unit 300 and maintains the tension of the threshold value, or the method such as to terminate the coupling between the drive unit 300 and the winch drum 350, the winch drum 350 freely It may be controlled to rotate (S930).

The controller 500 may also determine whether the tension of the wire 200 is smaller than a predetermined lower threshold (S940). While the user is using the electric strength exercise apparatus according to an embodiment of the present invention, the user may place the gripper 100 due to fatigue or other special circumstances. When the user applies the force and thus removes the force, the tension applied to the wire 200 may be close to zero. Even in this case, if the driving unit 300 applies a torque to match the tension of the wire 200 to the set load, the unsupported holding unit 100 may move and may cause damage or injury to a nearby object or person. Dangerous situations may result.

Therefore, when it is determined that the tension of the wire 200 is smaller than the predetermined lower threshold value, the control part 500 may stop the operation of the driving part 300 (S950) and control the gripping part 100 to stop at the current position. The lower threshold may be set to an appropriate value in consideration of this purpose.

Although not shown, in the electric strength exercise device control method according to an embodiment of the present invention, if the tension of the wire 200 measured by the tension sensor unit 400 is maintained below a predetermined lower threshold for a predetermined time The control unit 500 may rotate the winch drum 350 until the gripper 100 reaches a predetermined position or until the distance to the winch drum 350 is within a predetermined range. For this reason, the gripper 100 may be wound around the wire 200 so that the unsupported gripper 100 may be supported by the casing 600 or a separate supporter, and the gripper 100 may be disposed at a specific position.

8 is a flow chart showing a control method of the electric muscle exercise apparatus according to another embodiment of the present invention.

First, the electric strength exercise apparatus according to an embodiment of the present invention may be set the load and the number of reps for the user's exercise (S900). As described above, this process may be a process of directly inputting by the user, a process of inputting through another device, or a process set during manufacturing.

The number of reps here represents the number of reps to repeat when the user exercises. Of course, if necessary, the user may further input the number of sets, and the user may input or select a more specific exercise program.

In the present embodiment, the step of measuring the tension of the wire 200 and maintaining the same as the set load (S1010) is such that the tension of the wire 200 is substantially the same as the set load in the control method described with reference to FIG. 6. It may be similar to the step (S960 ~ S990) of adjusting the torque of the driving unit 300, and a redundant description will be omitted.

Electric strength exercise apparatus according to an embodiment of the present invention can also provide a more various types of services in conjunction with the digital medium.

As the user exercises using the exercise device, the controller 500 controls the driving unit 300 to maintain the tension of the wire 200. The wire 200 may be wound around the winch drum 350 by the torque of the driving unit 300 when the user does not apply the force, and when the user applies the force, the wire 200 may be released from the winch drum 350. Can be.

Using this, the controller 500 may determine whether the wire 200 is wound by a predetermined length during exercise of the user (S1020). The length over which the wire 200 is wound may be calculated using, for example, the angle or number of times the winch drum 350 is rotated.

When the length on which the wire 200 is wound reaches the set length, the controller 500 may then determine whether the wire 200 is unwound by a predetermined length (S1030). The length of the wire 200 is released may be the same as the length of the wire 200 is wound.

When the length of the wire 200 is released reaches the set length, the controller 500 may increase the number of reps by 1 (S1040). In Figure 8, the number of reps is represented by R.

The controller 500 may then determine whether the number of reps R matches the predetermined number of reps (S1050). When R reaches the set number of reps, the control unit 500 may output the corresponding information to the user through the touch display 520 or a voice message for guidance, and in some cases, stop the operation of the driving unit 300. have.

The predetermined length value with respect to the length of the wire 200 is wound may be set corresponding to the length of the grip 100 is moved when the user is exercising. Since the movement distance of the gripper 100 may vary according to the fatigue level of the user during the strength exercise, the set length may be preferably set to be less than or equal to the movement distance of the gripper 100.

As described above, the preset length value with respect to the length of the wire 200 may be input by the user, or may be set by the controller 500 using data analyzed during the exercise of the user. This may be set at the time of manufacture.

In FIG. 8, assuming the squat motion shown in FIG. 5C, the number of reps is increased by 1 when the wire 200 is wound by the set length and then unwound by the set length. In some cases, such as a) and (b), the number of reps may be increased by 1 when the wire 200 is unwound and then rewound.

Those skilled in the art will understand that the control method for tracking the number of reps as shown in FIG. 8 is just one example for various exercise programs possible in the present invention. Since the electric strength exercise apparatus according to an embodiment of the present invention is linked with a digital medium, it is possible to collect various kinds of information related to the user's exercise, and can provide a very wide range of exercise programs using the same.

For example, when the user inputs the set number as well as the number of the reps, the electric strength exercise apparatus according to an embodiment of the present invention can track both the reps number and the set number in response thereto and output various guide messages. And it can be possible for the user to enjoy the exercise program conveniently.

According to various embodiments of the present invention described above, there is provided an electric strength exercise device and a control method thereof, which are significantly smaller and lighter than the existing strength exercise device, and can provide a similar feeling of movement.
