And Figure 6 is a view showing the belt support structure of the first wheel and the second wheel. 1 to 6 , the moving bike device 10 according to the embodiment of the present invention includes a main body 200, driving units 410 to 440, and connection units 310 to 340. In the moving bike device 10, the main body 200, including the saddle 240 on which the user sits, is entirely moved along a preset movement trajectory while floating in the air, thereby providing a sense of speed and thrill while using the bike.

The body part 200 is disposed spaced apart from the base part 120 on the upper side of the base part 120 supported on the bottom surface, and may be formed in a predetermined bike shape. The base part 120 may be provided in a plate shape erected upward at a position where the driving part is provided in the bottom base part 110 . The base part 120 may be formed in a structure that is separated and combined with the bottom base part 110 . The base part 120 may be provided in a symmetrical shape on both sides so that the driving part is disposed therein. A load cell 112 for sensing the user's weight may be provided at a support position where the floor base part 110 and the floor surface come into contact with each other. Eight load cells 112 may be applied. Due to the load cell 112, it is possible to measure body weight even if the user only rides. A rubber foot may be separately provided at the support position. In addition, the level of the bottom base part 110 can be adjusted using the height adjustment bolt.

The heart rate sensor 270 provided on the handle part 250 may be formed of a conductive metal material. The heart rate sensor 270 may be operated by contacting the user's radial artery, which is a ventral portion under the user's thumb. Measurement data of the heart rate sensor 270 may be displayed on the display unit 260 in real time. The heart rate sensor 270 may include a body mass analysis function.

The body part 200 may have a preset inclination angle and be connected to the base part 120 . The body unit 200 may include a frame unit, a first wheel 210, a second wheel 220, and a power transmission unit.

The frame portion supports the saddle 240 and has a preset shape and functions to support the main body portion 200 . The frame unit may include a main frame provided at the center, a first support frame 214 connected to the first wheel 210, and a second support frame 216 connected to the handle.

The first wheel 210 includes a crank wheel provided on one side of the frame unit and rotated by a pair of pedals 212 rotational motion. A rotational speed detection sensor provided on the first wheel 210 to detect the rotational speed of the first wheel 210 may be further included. The controller may further include a control unit that analyzes information related to the number of revolutions of the first wheel 210 received from the rotation speed detection sensor and controls driving and rotation speed of the driving motor 410 . The control unit may implement overall control operations related to driving of the moving bike, including content driving and subscriber authentication, based on information stored in the memory. For example, the controller may calculate the movement distance according to pedaling using the rotational speed of the first wheel 210 detected by the rotational speed detection sensor.

When the user starts pedaling, the small protrusions fixedly coupled at intervals along the circumferential direction of the first wheel 210 rotate together, and the rotation speed detection sensor recognizes this to detect the rotation speed of the first wheel 210. there is. The operating principle of the rotation speed detection sensor is the principle of recognizing rotation when the infrared rays between the light emitting part and the receiving part are blocked by the protrusion. The controller may analyze information related to the number of revolutions of the first wheel 210 received from the rotation speed detection sensor and calculate the rotation speed of the first wheel 210 through the number of protrusions passed per unit time.

The controller may control driving and rotational speed of the drive motor 410 using rotational speed data of the first wheel 210 received from the rotational speed detection sensor. For example, if the user slows down the pedaling, the rotation speed of the first wheel 210 is detected slowly, and the drive and rotation speed of the drive motor 410 can be controlled to react slowly. Unlike this, if the user pedals quickly, the rotational speed of the first wheel 210 is quickly detected, and the driving and rotational speed of the driving motor 410 react quickly in response to this, real-time linked moving control is possible.

Meanwhile, the display unit 260 may further include scrolling of web content displayed on the screen or switching the screen in association with the number of revolutions of the first wheel 210 . The controller may control the screen displayed on the display unit 260 at a speed corresponding to the speed of the first wheel 210 according to the user's pedaling. In the moving bike device 10 according to an embodiment of the present invention, web content can be scrolled or screen switched through the display unit 260 by pedaling by the user. Therefore, it is possible to induce the user to exercise continuously and to motivate the user to exercise without getting bored.

The second wheel 220 is provided on the other side of the frame unit and rotates by receiving rotational force of the first wheel 210 . The second wheel 220 may include a magnetic disk. When the user pedals, the first wheel 210 and the second wheel 220 connected by the belt 230 may rotate at a ratio of 1:9. The second wheel 220 may be formed so that eddy current is generated by magnets attached to the left and right of the two drums connected to the pulley and aluminum plates provided on both sides of the drum. That is, the rotational strength of the second wheel 220 can be adjusted by the repelling force of the eddy current. A one-way clutch bearing is provided inside the pulley to perform a function of transmitting power only in a forward direction like a ratchet wheel hub. The strength of the eddy current can be determined by the contact area between the aluminum plate on the drum and the magnet. For example, the larger the area where the aluminum plate and the magnet face each other, the stronger the repulsive force. Therefore, the strength can be adjusted according to how much the depth of the magnet is inserted and removed. The servomotor can control the depth of the magnet by moving the rail united with the magnet as a link between the two.

The power transmitting unit transmits rotational power of the first wheel 210 to the second wheel 220 between the first wheel 210 and the second wheel 220 . The power transmission unit includes a belt 230 .

The driving unit is provided on the base unit 120 to provide movement power for the body unit 200 . The driving unit may include a driving motor 410 that generates rotational force separate from the rotation of the first wheel 210 and provides driving force to the driving wheel provided on the base unit 120 . The base unit 120 may further include a deceleration unit that transmits rotational power of the driving motor 410 to the body unit 200 through a driving wheel. The transmission system of power generated from the driving unit includes a driving motor 410, a first reduction unit 420, a second reduction unit 430, and a third reduction unit 440, and the power of the driving motor 410 is It may be adjusted to a final reduction gear ratio of 100:1 and transmitted to the third reduction unit 440. That is, the driving unit includes one driving motor 410 and three reduction units, and each may be fixed to the base unit 120 . The driving motor 410 and the first deceleration unit 420 to the third deceleration unit 440 may be provided as a combination of corresponding pulleys and gears, respectively, to implement a reduction gear ratio. The driving motor 410 may be provided with a capacity of consuming low power of DC 200W. The third deceleration unit 440 to which the power of the driving unit is finally transmitted includes a driving wheel, and a fixed shaft may be provided at a portion eccentric about 50 mm from the center of the driving wheel.

The connecting part connects the base part 120 and the main body part 200 so that the main body part 200 can maintain a spaced state from the base part 120 . The connecting portion supports air movement in which the body portion 200 moves along a movement trajectory in the form of preset interpolating curves.

The connecting portion may be formed in a multi-section link structure. The connection unit may be formed in a four-section link structure including a fixed support unit 310, a guide unit 340, a first link 320, and a second link 330.

The fixed support part 310 may be coupled to one side of the frame part supporting the body part 200 at the center of the body part 200 .

The guide part 340 may be long coupled to the base part 120 in a horizontal direction. The guide part 340 is moved by being coupled to the guide rail 342 that is long fixedly coupled to the horizontal direction on the upper side of the base part 120, and the lower part of the guide rail 342, and the upper part of the second link 330. The other end may include a moving block 344 hinged.

One end of the first link 320 is hingedly connected to one side of the fixed support part 310 and the other end is connected to the drive wheel as an eccentric shaft to be driven. That is, the first link 320 serving as the main shaft of the connection unit may be connected to the fixed shaft of the drive wheel. One side of the first link 320 is eccentrically connected to the fixed shaft, and can perform a cam motion by reciprocating while being inserted into the bushing 352 of the bushing support 350 according to the rotation of the driving wheel. The first link 320 that is eccentrically connected to a driving wheel to which the driving force of the driving unit is finally transmitted and performs a cam motion may be hinged to one side of the fixed support 310 coupled to the main body 200 . One end of the first link 320 is provided with a hinge pin coupled with a bearing in contact with the belt 230 to realize the hinge function and the belt 230 idler function. A hinge is provided at an end of the first link 320 and may be connected to the fixed support 310 of the main body 200 through a hinge pin at the hinge portion. The hinge pin is combined with bearings on both sides to function as a main hinge, and the two middle bearings can function as idlers of the belt 230. That is, for the asymmetrical parabolic motion of the body portion 200 , the main hinge portion where the drive unit and the body portion 200 meet may also function as an idler of the belt 230 in the body portion 200 . By seating the belt 230 on the main hinge to perform an idler function in parallel, a slimmer belt 230 coupling structure can be implemented. In an embodiment of the present invention, the belt 230 may be installed on one side. Meanwhile, in order for the entire body portion 200 to move, it is necessary to limit the width of the body portion 200 . As the width of the main body 200 increases, the user may experience discomfort in pedaling.

The second link 330 may have one end hingedly connected to the other side of the fixed support part 310 and the other end hingedly connected to the guide part 340 so as to be moved in the forward and backward directions and driven. That is, the second link 330 that linearly moves the rail through the guide part 340 constrained to the base part 120 may be hingedly connected to the other side of the fixed support part 310 . A plurality of second links 330 may be provided at symmetric positions left and right around the second wheel 220 . In this way, the combination of the fixed support part 310, the first link 320, the second link 330, and the guide part 340 can implement the movement trajectory movement of the airfoil shape, which is the cross section of an aircraft wing. That is, as the second link 330 is subordinate to the guide unit 340 and performs linear motion, a part of the cam motion of the first link 320 is restricted to linear motion, so that the upper part is parabolic and the lower part is close to a straight line. It is possible to implement a linear parabolic motion.

The connecting portion has one side connected to the base portion 120 and the other side to the bushing support 350 connected to the bushing 352 at a preset point along the longitudinal direction of the first link 320, and one side to the bushing support 350. This hinge connection, the other side is hinged to the base portion 120 may further include an auxiliary support portion 360 for supporting the movement of the bushing support portion 350. The base part 120 may be provided with a structure for coupling the bushing support part 350 for supporting the bushing 352 connected to the first link 320 and the auxiliary support part 360 . The bushing 352 may include a rotary linear bush.

As described above, in the moving bike device 10 according to the embodiment of the present invention, the main body 200 including the saddle 240 on which the user sits is floating in the air, moving forward and upward, and backward and downward as a whole. It moves along a preset movement trajectory and can provide a sense of speed and thrill while in use. In addition, an image such as a road view displayed through the display unit 260 provided on the front of the body unit 200 provides a sense of realism, and an environment such as an indoor or outdoor bike exercise experience can be provided.

As shown in FIGS. 4 and 5 , the final movement of the main body 200 according to the driving of the driving unit may be implemented as a repeated movement.

When expressed as a trajectory centered on the saddle 240, a sense of speed as if moving forward can be felt. In addition, psychological stability can be obtained through flexible movement without the user's hip pressure, and the movement angle of the display unit 260 is small, so it is possible to feel comfortable focusing on the content displayed on the display unit 260 . When a user seated on the actual saddle 240 experiences the motion of a moving trajectory, there is almost no feeling of up and down motion.

Existing indoor bikes have fixed saddles, so you cannot feel the sense of speed like outdoors. In an indoor space where space is limited, there is no choice but to use exercise equipment in a fixed environment. Even under these limited conditions, you can feel the speed of the bike.

As a way to give a sense of speed in place, you can think of going forward and backward, or going up and down. However, the user does not feel the sense of speed well when moving forward and backward in place. Surprisingly, the part where you feel a lot of speed is when you go up, and considering this, you can provide an asymmetrical parabolic motion. For example, when the main body 200 moves forward, the sense of speed may be increased while giving a slight sense of elevation, and when returning to the original position, the sense of speed may be halved by returning to the original position without a difference in altitude. By providing such an asymmetrical parabolic motion, the user mainly feels only the sense of speed going forward, so that the user can get the feeling of going forward like outdoors.

As described above, the movement trajectory of the main body 200 may be operated in a pattern in which acceleration-upward movement, deceleration-downward movement, and rectilinear backward movement are repeated from the starting point of use, which is the initial position. The movement trajectory operation can be appropriately adjusted according to the user's settings. For example, a movement trajectory operation of feeling that the main body 200 tilts forward or leans back may be implemented continuously.

On the other hand, the home position function can be applied because the use start point for the movement trajectory of the body unit 200 must always start at the same location. Here, the home position can be set to always start at the starting point of use when restarting at any position by mounting a photosensor that functions as a light emitting unit and a receiving unit. For example, the drive wheel of the tertiary deceleration unit is provided with two sensing holes (at 3 o'clock and 9 o'clock positions corresponding to each other), so that the location of the drive wheel can be detected every time the drive wheel rotates half a turn. By detecting the rotation of the driving wheel through the two sensing holes, the control of the driving unit can be implemented in various ways. For example, the driving wheel may be rotated normally for half a turn and accelerated during the other half turn. In addition, half of the rotation of the driving wheel may be rotated forward and the other half rotation may be reversed. The control operation of the driving wheel may be interlocked with the rotation speed detection sensor of the first wheel 210 to implement more rotation control operations.

The moving bike device 10 according to the embodiment of the present invention may further include a position adjusting unit provided under the saddle 240 to adjust the position of the saddle 240 . FIG. 7 is a view showing the coupling relationship of the position adjusting unit for adjusting the position of the saddle 240, and FIG. 8 is a view showing the position adjustment sequence of the saddle 240.

One side of the lever unit 540 is hinged to the other side of the support frame 510 so that it can be rotated. The lever unit 540 may function as a handle for adjusting the position of the saddle 240 .

The control unit 542 is provided inside the lever unit 540 and a selection point is hinged to the other side of the support frame 510 to function as a lever. A first end of the adjusting unit 542 is hinged to the second end of the fixing unit 530 so that it can rotate. A second end of the control unit 542 may be exposed to the outside of the lever unit 540 along the longitudinal direction.

The position control unit may further include a push button 560, a locking groove 564, a locking portion, a tension spring 566, and a compression spring 568.

The push button 560 may be provided at the second end of the control unit 542 . The locking groove 564 may be provided at a connection position of the lever unit 540 on the other side of the support frame 510 . One end of the locking part is interlocked with the pressing operation of the push button 560, and the locking pin 562 provided at the other end can be separated from the locking position of the locking groove 564. The locking portion and the locking pin 562 may be integrally provided. One side of the tension spring 566 is coupled to the other side of the support frame 510 and the other side is coupled to one side of the lever unit 540 to support the restoring force of the lever unit 540 . A compression spring 568 may be provided on one side of the push button 560 to provide a restoring force of the push button 560 .

According to the method of adjusting the front and back of the saddle 240 according to the embodiment of the present invention, the user can adjust the saddle 240 in just a few seconds without exerting unnecessary force. In addition, since the saddle 240 never moves unless the handle is raised after unlocking, safety accidents can be prevented in advance.

Referring to FIG. 8, a sequence of adjusting the position of the saddle will be described.

S10. Assuming that the saddle 240 is fixed, the user presses the push button 560 by hand to unlock the saddle 240 . When the push button 560 is pressed, the locking pin 562 comes out of the locking position of the locking groove 564 and becomes rotatable. In order to release the locking function, the push button 560 pushed by the compression spring 568 can be pressed by hand to rotate the locking pin 562 hanging from the bottom of the 'L'-shaped locking groove 564. make it The locking groove 564 may be provided in a shape of about 90 degrees.

S20. When the user lifts the handle while pressing the push button 560, the tension spring 566 extends and the fixing part 530 holding the fixing pin 522 goes down. When the lever part 540 is lifted up by applying some force while pressing the push button 560, the tension spring 566 is stretched and rotated. When the push button 560 is pressed, the locking pin 562, which is in a locked state, is positioned at the top left of the locking groove 564. At the same time, as the locking pin 562 connected to the lower left side of the lever unit 540 by a link falls down, the fixing pin 522 fixing the saddle 240 can be free to move.
