Description

[0001] The present invention relates to a torque control device,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a torque adjusting apparatus and method, and more particularly, to a torque adjusting apparatus and method capable of automatically adjusting a torque required for driving a fitness apparatus according to a user's condition.

Torque is also referred to as rotational force or torque, and is a physical quantity indicating the effect of rotating an object. That is, torque is a measure of the action of a force applied to rotate an object. The torque can be defined as the vector product of the force vector and the distance vector to the fulcrum, and can also be defined as the amount of angular momentum change over time.

The torque of the vehicle engine can be expressed by the torque. The higher the torque, the higher the acceleration of the vehicle and the greater the strength. Therefore, in the case of a vehicle, the larger the maximum torque, the better the acceleration, and the higher the maximum output, the higher the maximum speed.

Even when a user performs exercise using a fitness device such as a fitness cycle or a rehabilitation exercise device using rotational motion, the user must constantly apply a torque equal to or greater than a predetermined magnitude.

However, in order to maximize the exercise effect, it is necessary to exercise at the exercise intensity appropriate to the user's exercise goal. For example, if exercise goals are changed, such as professional training, cardiopulmonary endurance, weight loss, or beginners' exercise, then the exercise intensity needs to vary accordingly. In addition, there is a need to change the exercise intensity according to the user's physical condition or fatigue.

Therefore, it is necessary to consider a device capable of automatically adjusting the torque required for driving the exercise machine according to the physical condition of the user who is exercising using the exercise device, thereby providing a proper exercise load to the user.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a torque control apparatus and method capable of automatically adjusting a torque required for driving a fitness instrument according to a user's condition to provide a suitable exercise load for a user's condition.

According to an aspect of the present invention, there is provided a torque control device including a sensor unit for measuring a bio-signal of a user driving a fitness device, a torque adjustment unit for adjusting a torque required for driving the fitness device, And a controller for controlling the torque adjuster so that the torque required for driving the exercise machine changes according to the measured bio-signal.

The torque control unit may include a servomotor whose driving is controlled by a control signal of the control unit, a pedal disk having a pedal shaft connected to the central shaft, And a belt driving unit for rotating the pedal disk through a driving belt connected to the pedal disk.

According to the present invention, it is possible to automatically measure the torque necessary for driving the exercise machine according to the state of the user by measuring the bio-signal of the user exercising using the exercise device. Accordingly, it is possible to increase the exercise effect by providing the exercise intensity suitable for the user's condition, and to prevent the injury due to excessive exercise. In addition, it can be applied to a rehabilitation exercise apparatus to enhance the effect of rehabilitation treatment, and may be applied to a game apparatus or the like to induce a user's interest.

FIGS. 2 to 4 are views showing an example of the configuration of the torque adjusting unit, and FIGS.
5 is a flowchart showing a method of driving a torque control apparatus according to an embodiment of the present invention.

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

1 is a block diagram of a torque control apparatus according to an embodiment of the present invention.

Referring to FIG. 1, the present torque regulator 100 may include a sensor unit 110, a user input unit 120, an output unit 130, a torque control unit 140, and a control unit 150. When such components are implemented in practical applications, two or more components may be combined into one component, or one component may be divided into two or more components as necessary.

The sensor unit 110 measures a living body signal such as body temperature, sweat, and heart rate of a user driving the exercise device 200. An example of the exercise device 200 is a fitness cycle or a rehabilitation exercise device using rotational motion.

The user input unit 120 generates key input data for controlling or setting the operation of the torque adjusting device 100 by a user. The user's age, sex, heart rate at rest, etc., can be input through the user input unit 120.

The output unit 130 is for outputting a video signal, an audio signal, or an alarm signal, and may include a display, an audio output module, and the like.

The torque adjusting unit 140 adjusts the torque for driving the exercise device 200 under the control of the controller 150. [

The controller 150 typically controls the operation of each module to control the overall operation of the torque regulator 100.

According to the configuration, the control unit 150 grasps the state of the user according to the change of the bio-signal measured by the sensor unit 110, adjusts the torque according to a predetermined condition according to a user's input, The control unit 140 controls the torque for driving the exercise device 200.

Figs. 2 to 4 show an example of the configuration of the torque adjusting section. Here, the case where the exercise device is a health cycle will be described as an example.

2 to 4, the torque adjusting unit 140 may include a servo motor 141, a belt driving unit 143, a driving belt 145, and a pedal disc 147.

The servo motor 141 is controlled by the control unit 150 to provide a driving force. The driving force of the servo motor 141 is transmitted to the belt driving unit 143 and the belt driving unit 143 rotates the pedal disc 147 via the driving belt 145.

A pedal (not shown) is connected to the pedal shaft 148 provided on the central axis of the pedal disc 147, and the user can move the pedal to drive the fitness cycle. Although not shown in the drawings, the flywheel may further include a flywheel (not shown) having a high moment of inertia to increase the efficiency of rotational motion by the pedal.

The driving of the servomotor 141 is controlled in accordance with the control signal of the controller 150 so that the belt driving unit 143 transmits the rotational force to the pedal disk 147 via the driving belt 145 . Thus, the torque for driving the fitness cycle by the user moving the pedal can be adjusted.

5 is a signal flow diagram provided in the description of a method of operation of the torque regulating device according to an embodiment of the present invention.

Referring to FIG. 5, the sensor unit 110 measures a living body signal such as body temperature, sweat, and heart rate of a user during exercise by moving the exercise device 200 (S300).

The bio-signal measured by the sensor unit 110 is transmitted to the controller 150. The controller 150 compares the previously set and stored set value with the measured bio-signal to grasp the state of the user, It is determined whether torque adjustment for driving the motor 200 is necessary (S310, S320).

As a result of the determination in step S320, if it is necessary to change the torque, the torque control unit 140 transmits a control signal for adjusting the torque to a predetermined torque magnitude (S330). Accordingly, the torque adjusting unit 140 adjusts the torque for driving the exercise device 200 (S340).

This process is repeatedly performed until the exercise using the exercise device 200 is terminated (S350).

According to this process, the torque for driving the exercising device can be automatically adjusted according to the biological signal of the user driving the exercise device, thereby providing the exercise intensity suitable for the user.

However, the present invention is not limited to this, and may be applied to a case where a torque is adjusted in accordance with a physical condition of a user in a recycling exercise machine using a rotational motion, a game machine, or the like It is applicable.
