More specifically, the casing 100 may be formed as a hollow hexahedron having a long length in the vertical direction, for example. A sliding slot 110 is formed on one surface of the casing 100, that is, on the front surface thereof. The sliding slot 110 is formed by cutting a part of the front surface of the casing 100 up and down.

The sliding unit 200 is installed in the casing 100 so as to be linearly movable in the vertical direction. More specifically, the sliding unit 200 includes a sliding block 210. The sliding block 210 may be formed in a polygonal shape having a cross section corresponding to the cross section of the casing 100, for example. A driving hole 211 and a pair of guide holes 213 are formed in the sliding block 210. The drive boss 420 and the guide boss 920 are coupled to the drive hole 211 and the guide hole 213, respectively. For example, the guide holes 213 may be formed on both sides of the driving hole 211. Further, the sliding block 210 is provided with a fixing piece 215. The fixing piece 215 is provided at one side of the sliding block 210 and is exposed to the outside of the casing 100 through the sliding slot 110. A wire (not shown) may be connected to the fixing piece 215 so as to allow the user to move the sliding block 210 upward with respect to the casing 100. Of course, a handle (not shown) for gripping the user may be directly connected to the fixing piece 215.

The driving motor 300 is installed inside the casing 100 and rotates by a power source to generate a driving force. As the driving motor 300, various types of motors, such as a BLDC motor and a servo motor, may be used. The driving motor 300 is provided with a motor shaft 310 that is coupled to the driving bar 410 and rotates. The driving motor 300 is fixed to the inside of the casing 100 by a motor bracket 320. A decelerator 330 for decelerating the rotational speed of the motor shaft 310 is disposed substantially between the motor shaft 310 and the drive bar 410.

The driving force transmitting portion 400 transmits the driving force of the driving motor 300 to the sliding unit 200. In the present embodiment, the driving force transmitting portion 400 includes a driving bar 410 and a driving boss 420. The driving bar 410 is vertically disposed inside the casing 100. One end of the driving bar 410, that is, the lower end of the driving bar 410 is coupled to the motor shaft 310 and rotates in conjunction with the rotation of the motor shaft 310. A thread is formed on the outer peripheral surface of the driving bar 410. The driving boss 420 is coupled to the driving hole 211. A screw thread is formed on the inner circumferential surface of the driving boss 420 in a state where the driving boss 420 is coupled to the driving hole 211 and screwed into the thread of the driving bar 410.

The input unit 500 receives an operation signal for setting a torque of the drive motor 300. Actually, the input unit 500 may convert an amount of motion required for the user to move the sliding unit 200 upward according to the torque of the driving motor 300, and receive the operation signal.

The second sensor 620 is positioned below the first sensor 610 and the third sensor 630 is positioned below the first sensor 610. In this embodiment, And is located above the sensor 610. For example, when the user performs weight training, the first and second sensors 610 and 620 detect a position where the sliding unit 200 moves excessively downward with respect to the casing 100 And the third sensor 630 senses the position where the user has moved the sliding unit 200 upward with respect to the casing 100 for weight training.

The braking device 700 and the decelerator 800 stop the sliding unit 200 moving downward from the inside of the casing 100 or lower the moving speed of the sliding unit 200 downward It slows down. The braking device 700 can stop the rotation of the driving bar 410 or increase the friction between the sliding unit 200 and the casing 100 or the driving bar 410 . As the decelerator 800, an eddy-current brake may be used. For example, the decelerator 800 includes a conductor 810 that is vertically disposed on both sides of both sides of the casing 100, and a magnetic body 820 provided on both sides of the sliding unit 200 . Therefore, when the sliding unit 200 moves downward with respect to the casing 100, an eddy current is generated between the conductor portion 810 and the magnetic body 820 in accordance with the right-hand rule of Fleming, A torque in a direction opposite to the moving direction of the sliding unit 200 moving downward due to the eddy current and the magnetic field of the magnetic body 820 is generated. Accordingly, the downward movement speed of the sliding unit 200 is reduced.

In addition, the fitness exercise device 1 including the gravity control module according to the present embodiment may further include a guide bar 910 and a guide boss 920. The guide bar 910 is formed in the casing 100 in a pair in a direction parallel to the driving bar 410. The guide bosses 920 are coupled to the guide holes 213, respectively. The guide bar 910 is inserted through the guide boss 920 in a state where the guide boss 920 is coupled to the guide hole 213 so that the sliding unit 200 Can be prevented.

Meanwhile, the control unit 1000 applies power to the driving motor 300 so that the input unit 500 is driven at a set torque according to an input operation signal. Particularly, in the present embodiment, when power is applied to the driving motor 300 by the control unit 1000, the driving motor 300 moves the sliding unit 200 downward from the inside of the casing 100 As shown in Fig. The sliding unit 200 moves upward by the user in a state in which the driving force of the driving motor 300 is supplied, thereby performing weight training of the user.

In the present embodiment, the control unit 1000 controls the driving motor 300 such that the driving motor 300 is driven at a set torque or less than a set torque, depending on whether the sliding unit 200 moves upward with respect to the casing 100 by the user As shown in Fig. In other words, when the load is generated in the driving motor 300 due to the upward movement of the sliding unit 200, the control unit 1000 controls the driving motor 300 to be driven at a set torque . When the load is not generated in the driving motor 300 due to the downward movement of the sliding unit 200, the controller 1000 drives the driving motor 300 at a torque less than the set torque Respectively. This is because when the user performs the weight training in an uncomfortable posture in which the sliding unit 200 is lowered downward compared to the operation of lifting the sliding unit 200 upwardly, In order to prevent inconvenience caused by

Also, in this embodiment, the controller 1000 cuts off the power applied to the driving motor 300 or operates the braking device 700 according to the position of the sliding unit 200. For example, when the sliding unit 200 is sensed by the first sensor 610, the controller 1000 may cut off the power applied to the driving motor 300. When the sliding unit 200 is detected by the second sensor 620, the braking device 700 can be operated.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the above teachings. will be.
