Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a load control device according to an embodiment of the present invention.

The load control device of this embodiment is a device for precisely controlling the load using a plurality of drive devices, for example, electric motors, and can be used as an exercise device, a rehabilitation device, a calibration device, an industrial device, and the like. That is, the load control device may be used in various fields requiring precise load control, but is not limited to a specific field.

Hereinafter, for convenience of description, the load control device will be assumed as an exercise device.

Referring to FIG. 1, the load control device of the present embodiment includes a first driving device 100, a second driving device 102, a first frame 104, a second frame 106, a first moving part 108, and The second exercise unit 110 is included.

The driving device 100 or 102 is a device for generating a specific load, and may be, for example, an electric motor that generates a predetermined rotational force in response to a current (or voltage) provided from an instrument control unit (not shown). Here, the electric motor includes a high performance motor capable of high cost or precise control, and a low performance motor such as a motor having low cost or difficulty in precise control. However, even in the case of a low-performance motor is required for precise control of the load, the load control device using the low-performance motor should include more components for the precision control than the load control device using the high-performance motor. Detailed description thereof will be described later.

In addition, the driving device 100 or 102 may perform isotonic motion, constant velocity motion, isometric motion, ROM motion, and the like under the control of the mechanism controller. Here, the isotonic exercise is an exercise for maintaining a constant rotational force during exercise, and represents an exercise performed with a weight in a general exercise equipment. The constant velocity motion refers to an exercise of maintaining a constant rotational speed during the exercise, and the constant motion represents a motion performed by the user to train a specific muscle part while the frame is fixed. The ROM movement is a movement widely used for rehabilitation, and means a movement in which a corresponding frame automatically moves within a certain range even if a user does not apply force.

The first frame 104 is directly / indirectly connected to the first driving device 100 and moves back and forth, for example, according to the driving of the first driving device 100.

The second frame 106 is directly / indirectly connected to the second driving device 102 and moves according to the driving of the second driving device 102. For example, when the first frame 104 moves backward, the second frame 106 may move forward. Of course, the frames 104 and 106 may move in the same direction. This operation method may be set by the user as an external operation or may be preset as a specific mode in the load control device.

The exercise units 108 and 110 are portions to which the user's force is applied, for example, exercise handles. Of course, since the moving parts 108 and 110 are connected to the frames 104 and 106, they move in the same direction as the movement of the frames 104 and 106. For example, when the exercise unit 108 exerts a force in the rear direction, the user may exercise by pushing the exercise unit 108 in the forward direction. These exercise units 108 and 110 are not limited to any particular form as long as they come in contact with a user's body part.

In short, the load control device of the present embodiment, for example the exercise device, generates a load using a plurality of drive devices 100 and 102, preferably electric motors. Here, the first driving device 100, the first frame 104 and the first moving part 108 are referred to as a first load device, and the second driving device 102, the second frame 106 and the second moving part 110 are referred to as first load devices. ) As the second load device, the load control device can independently drive the first load device and the second load device. As a result, the load amount, load control time, movement direction, etc. for the first load device may be different from the load amount, load control time, movement direction, etc. for the second load device. That is, the motion trajectory of the first load device may be different from the motion trajectory of the second load device.

By driving the load devices independently in this way, the user's movement imbalance can be changed to a balanced state. For example, in the case of the right hand, the right hand is generally stronger than the left hand, so the first load device for the right hand generates a greater load than the second load device for the left hand, so that the right hand motion and the left hand motion are balanced. Can be done. As another example, if the right leg muscle is more developed than the left leg muscle and needs to develop the left leg muscle for a balanced body, the second load device for the left leg is larger than the first load device for the right leg. A load may be generated, i.e., a greater load is applied to the left leg so that the muscles of the left leg are further trained even if the right and left legs exercise the same time. That is, the load devices may generate different loads (load deviations) according to the situation.

As such, the load control device may maintain the exercise state of the user in a balanced state, and thus may be suitable for rehabilitation treatment and orthodontic treatment.

In the above, only two load devices are mentioned, but three or more load devices, ie three or more drive devices, may be used. For example, four load devices for the left arm, right arm, left leg and right leg can be used. In this case, the user can train the left arm muscle, the right arm muscle, the left leg muscle, and the right leg muscle, respectively. In addition, the load device may form a different movement trajectory for each training (treatment) site as will be described later.

In the above description, although the load devices are initially set to appropriately set the load for each body part, the load control device of the present embodiment initially controls the load devices to generate a predetermined load, Afterwards, the exercise device may be measured to control the load devices such that the exercise state of the user is in a balanced state. That is, the load control device controls the load devices to generate loads with a load deviation so as to be in a balanced state when it is determined that the movement of the user is unbalanced. Of course, this control process can be performed automatically.

In addition, although the frames 108 and 110 are shown as moving forward and backward in FIG. 1, the frames may be moved up and down and left and right according to the configuration of the load control device. In this case, the movement trajectories of the front, rear, up and down movements, and the left and right movements may all be different. Since the load devices are driven by changing the motion trajectory as described above, the load control device may be applied for training of various sports such as running, golf, swimming, weight lifting, and fitness.

Hereinafter, the components of the load control device of the present embodiment will be described in more detail.

2 is a diagram illustrating a load control device according to an embodiment of the present invention. However, it is assumed that two load devices are used as shown in FIG. 1 for convenience of description.

Referring to FIG. 2, the load control device of the present embodiment includes a first load device, a second load device, a mechanism control unit 200, a first drive control unit 202, a second drive control unit 204, and a load deviation unit 206. And the instrument operation unit 208. The first load device includes a first drive device 100, a first frame 104, and a first moving part 108, and the second load device includes a second drive device 102 and a second frame ( 106 and the second movement unit 110.

When the driving device 100 or 102 is an electric motor, as is well known to those skilled in the art, the driving device 100 or 102 includes a body and a rotating shaft inserted into the body and rotating. In this case, the rotating shaft rotates in proportion to the current (or voltage) provided under the control of the instrument control unit 200, so that the frame 104 or 106 rotates in the same direction as the rotating direction of the rotating shaft.

The drive device 100 or 102 and the corresponding frame 104 or 106 may be connected in various ways using a gear, a pulley, a belt, or the like, and such a connection method may be easily implemented by those skilled in the art. Therefore, detailed drawings and descriptions will be omitted below.

The instrument control unit 200 is a device for driving the driving devices 100 and 102. For example, the instrument control unit 200 provides the driving devices 100 and 102 by providing a specific current (or voltage) to the driving devices 100 and 102. Drive it. In particular, since the instrument controller 200 may independently drive the driving apparatuses 100 and 102, the apparatus control unit 200 may provide different currents (or voltages) to the driving apparatuses 100 and 102.

The drive controllers 202 and 204 drive the corresponding drive devices 100 and 102 under the control of the instrument controller 200.

The load deviation unit 206 measures a user's exercise data using a sensor or the like, for example, data on a position, force, exercise amount, muscle strength, etc. of the exercise portion, and transmits the information on the measured data to the instrument control unit 200. Can be provided as For example, the load deviation unit 206 may couple the sensor to the rotating shaft of the driving device 100 or 102 to detect the motion data through the rotation of the rotating shaft. As another example, the load deviation unit 206 may detect the exercise data by measuring the force applied by the user by coupling the sensor to the exercise unit 108 or 110. That is, the detection of the exercise data of the user may be variously modified, and the exercise data is not limited to specific information.

The instrument control unit 200 analyzes the information provided from the load deviation unit 206 to determine the state of movement imbalance, and when it is determined that the state of imbalance, the load devices, that is, the driving devices 100 and 102 have a load deviation. Control to generate loads. As a result, the user can perform a balanced exercise.

According to another embodiment of the present invention, the load deviation unit 206 measures the user's exercise data through various methods, and automatically calculates the load deviation for the load devices according to the measured data, Information about the calculated load deviation may be provided to the instrument controller 200. In this case, the instrument control unit 200 may automatically control the load devices according to the provided information so that the load deviation occurs.

The instrument control unit 200 may be connected to the external communication device 210 outside the load control device by wire or wireless, and may transmit information about measured data, exercise amount, etc. to the external communication device 210. As a result, the external communication device 210 may separately manage information about each user through the transmitted information, and transmit a specific control signal to the load control device so that the user can perform a corresponding exercise. It is also possible to control the load control device.

The instrument operating section 208 is a portion for which a user inputs a specific command, for example, provides the user with a specific mode. The user inputs various commands for an exercise method, an exercise setting, and the like through the mode selection.

In short, the load control device uses a plurality of drive devices capable of generating different loads in order to maintain a balanced motion. Here, if the drive device is a high-performance drive device can be implemented only with the configuration described above, the low-performance drive device requires the following configuration for precise control.

Hereinafter, a configuration of a load control device using such a low performance drive device will be described.

3 is a diagram illustrating a configuration of a load control device according to an embodiment of the present invention. 3 shows only a part related to one load device among the plurality of load devices, and assumes that the driving device is an electric motor.

Referring to FIG. 3, the load control device of the present embodiment includes the electric motor 100, the rotation member 304, the force transmission unit 306, the force adjustment unit 308, the force control unit 310, the frame 104, and the movement unit ( 108, a position / speed sensor 312, a load sensor 314, an instrument control unit 200, and a load deviation unit 206.

The electric motor 100, for example, a low cost motor, includes a body 300 and a rotating shaft 302.

The rotating shaft 302 is inserted into and fixed to the body 300, and rotates in proportion to the magnitude of the current (voltage) when a predetermined current (or voltage) is provided from the instrument controller 200 to the body 300. .

The rotating member 304 is a rotatable element, for example, a worm gear. The rotary member 304 is connected to the rotary shaft 302 of the electric motor 100, and preferably rotates in response to the rotation of the rotary shaft 302 in engagement with the rotary shaft 302. According to one embodiment of the invention, the rotational speed of the rotary member 304 is slower than the rotational speed of the rotary shaft 302 of the electric motor 100, that is, the rotary member 304 serves as a reducer.

The force transmission part 306 transmits the rotational force according to the rotation of the rotation member 304 to the frame 104 and the moving part 108. According to one embodiment of the invention, the force transmission portion 306 is fixed in the inserted state to the rotating member 304, and thus rotates together when the rotating member 304 rotates.

The force adjuster 308 engages with the force transmitter 306 and has a structure that encloses a portion of the force transmitter 306, for example. This force adjustment unit 308 controls the rotational power (rotational speed) of the force transmission unit 306, that is, the exercise load. For example, when the motor 100 is a motor, since the motor 100 may not accurately generate a predetermined exercise load, the force adjusting unit 308 may rotate the motor 100, that is, the rotational force of the rotating member 304. Fine adjustments can be made to control the desired exercise load to be transmitted to the frame 104. Of course, the position and structure of the force adjuster 308 may be variously modified as long as the force adjuster 308 adjusts the force transmission unit 306 to precisely control the exercise load.

According to one embodiment of the invention, the force adjustment unit 308 may be a clutch. In this case, a fluid such as an MR fluid, an ER fluid, or the like may be filled in the force adjuster 308. Herein, the fluid refers to a material that changes into a solid when an external source such as a magnetic field is applied. Of course, it is not limited to the clutch as long as the force adjustment unit 308 can precisely control the exercise load.

The force control unit 310 is connected to the force adjustment unit 308, and controls the operation of the force adjustment unit 308 using a magnetic field or the like. For example, when the force adjuster 308 is made of MR fluid, the operation of the force adjuster 308 may be controlled by adjusting the strength of the magnetic field.

This force control unit 310 is controlled by the instrument control unit 200. In detail, the mechanism control unit 200 operates the electric motor 100 and simultaneously controls the force control unit 310. That is, the mechanism control unit 200 controls the operation of the force control unit 310 in consideration of the rotational force generated from the electric motor 100, and as a result, the force adjustment unit 308 is a preset movement of the rotational force of the force transmission unit 306 Variable according to the load.

The position / speed sensor 312 is connected with the rotating member 304 or / and the force transmission unit 306, and detects the rotating position / rotation speed of the electric motor 100, for example, by rotating the rotating member 304. do.

The load sensor 314 is attached to one side of the exercise unit 108 to sense the magnitude of the force applied by the user, and as a result, the user's real-time exercise data can be accurately detected.

The load deviation unit 206 is connected to the sensors 312 and 314 to detect data sensed by the sensors 312 and 314 in real time, and provides information about the detected data to the instrument controller 200. do. In this case, the instrument control unit 200 sets loads for the load devices according to the information provided above.

In short, the load control device of the present embodiment improves the accuracy of the exercise load by using the force adjusting unit 308 while using a low-cost electric motor 100, for example, a DC electric motor. As a result, the load control device can lower the manufacturing cost while maintaining the precision of the kinetic load similar to when using a high performance electric motor.

The structure of the above load control device may be variously modified as long as the low-cost electric motor 100 is used and the force adjuster 308 precisely controls the exercise load.

4 and 5 are perspective views showing an actual implementation structure of the load control device according to an embodiment of the present invention.

The first driving device 100 drives the first moving parts 108a and 108b, and the second driving device 102 drives the second moving parts 110a and 110b.

The instrument control unit 200 controls the operations of the driving apparatuses 100 and 102, and for example, as shown in FIG. 5A, the first movement unit 108a is fixed while the second movement units 110a and 110b are fixed. And 108b) can be rotated in the right direction. In this case, the mechanism control unit 200 controls the rotation direction, the rotation speed, the rotation distance, and the like of the first movement units 108a and 108b. As a result, the first movement units 108a and 108b move to a specific distance with the right movement trajectory under the control of the instrument control unit 200. Of course, the instrument control unit 200 may move to the left position after the first movement unit (108a and 108b) to the maximum limit in the right direction to move back to the initial position or to the left maximum limit. As another example, the instrument controller 200 may rotate the first movement units 108a and 108b with the right trajectory, and rotate the second movement units 110a and 110b with the left trajectory. As a result, the user can perform upper body exercise, lower body exercise and waist exercise.

In other words, the instrument control unit 200 provides a different load for each body part using a plurality of driving devices, that is, drives the driving devices with a load deviation. As a result, the user can exercise by body part. In particular, since the load control device moves the exercise part with the motion trajectory for each part, the exercise of each part can be tempered or calibrated to the maximum at the minimum time.
