The case 410 supports the main frame 100 at a predetermined height or more from the bottom and accommodates the driving motor 420 and the gear unit 440 therein.

Specifically, as shown in the case 410, the upper portion has a main rotating shaft 402 at the center portion along the longitudinal direction of the main frame 100 and is rotatably coupled, and the lower portion is located on the bottom surface.

The drive motor 420 is provided inside the case 410 and is configured to rotate by the control unit to rotate the main frame 100 about the main rotation shaft 402.

Specifically, the driving motor 420 may be composed of at least one, it is connected to the main rotation shaft 402 to rotate the main frame 100 by a predetermined angle.

In this case, the driving motor 420 may be directly coupled to the main rotation shaft 402 with the same rotation shaft as the main frame 100, or alternatively, may be coupled through the gear unit 440 as shown.

On the other hand, the arc 430 is formed to protrude in the downward direction on the main frame 100 is configured to rotate the main frame 100 by receiving the rotational force of the drive motor 420, the arc shape on the main frame 100 The main rotating shaft 402 is formed to protrude in a downward direction so as to be located at the center of the arc.

As shown in detail, the circular arc part 430 is composed of a pair and is arranged to be symmetrical to the left and right of the main frame 100 and is fixed to the main frame 100 so that the center of the circular arc is located on the main axis of rotation 402. Combined.

In addition, the arc part 430 has a rack gear 432 protruding in the rotation axis direction on the inner surface of the arc, and is rotated about the main rotation shaft 402 by receiving the rotational force of the driving motor 420.

At this time, since the arc 430 is fixedly coupled to the main frame 100, the main frame 100 rotates together.

That is, the arc part 430 receives the rotational force by the driving motor 420 accommodated in the case 410 and the gear part 440 described later, and the rack gear 432 slides along the arc to rotate the main shaft 402. Rotate around.

In this embodiment, the arc part 430 has a rack gear 432 protruding in the direction of the main rotation shaft 402 on the inner side of the arc is engaged with the gear part 440 to be described later to improve the rotational force of the drive motor 420. I receive it.

On the other hand, the gear unit 440 is composed of at least one is connected to the drive motor 420, and meshes with the rack gear 432 formed in the arc portion 430 to rotate the arc portion 430.

Specifically, the gear unit 440 is connected to the rotation shaft of the drive motor 420 and rotates, and meshes with the rack gear 432 formed in the arc portion 430 to center the arc portion 430 around the main rotation shaft 402. To rotate.

In the present exemplary embodiment, the gear unit 440 is formed in a form in which a plurality of gears are engaged with each other. Alternatively, the gear unit 440 is composed of one gear and is directly connected to the driving motor 420, and at the same time the rack gear 432 ) May be configured to mate with

As described above, in the rotation unit 400 according to the present invention, the driving motor 420 configured therein is selectively driven by the control unit to adjust the inclination angle of the main frame 100.

Here, a load may be selectively provided to at least one of the first rear roller 322 or the second rear roller 324, and the rear wheel (corresponding to the inclination angle of the main frame 100 by the control unit) Provide the load for the rotation of 14).

In particular, the rear roller 320 generates a load for rotation when the main frame 100 is inclined by the rotating unit 400 to be described later and the rear wheel 14 changes to a position lower than the front wheel 12. .

As the load is generated on the rear roller part 320 as described above, more power is consumed when the user rotates the rear wheel 14 on the bicycle.

That is, when the inclination angle of the main frame 100 is adjusted so that the bicycle is arranged in the form of climbing the incline, a load is generated on the rear roller part 320 so that the user climbs uphill when the rear wheel 14 is driven. It will be hard.

In this embodiment, a description will be given taking an example in which the load generating means is provided in the second rear roller.

8 is a view showing the internal configuration of the second rear roller in the bicycle exercise apparatus of Figure 1, Figure 9 is a view showing the internal configuration of the first rear roller in the bicycle exercise apparatus of FIG.

Referring to the configuration of the second rear roller 324 with reference to Figures 8 and 9, the second rear roller 324 has a rotation axis in the rotation support portion 310 is configured to be rotatable and the rear wheel 14 on the outer surface Are configured to contact and rotate together by the rotation of the rear wheels 14.

Here, the second rear roller 324 is provided on the rear side along the longitudinal direction of the rotary support 310, the first rear roller 322 is provided on the front side along the longitudinal direction of the rotary support 310.

The second rear roller 324 according to the present invention includes a fixed shaft 324c, a second rotating drum 324a and a load generating means 324b.

The fixed shaft 324c is formed along the width direction of the rotation support part 310 by the rotation axis of the second rear roller 324 so that both ends are fixedly coupled to the rotation support part 310.

The second rotating drum 324a is configured to be rotatable by contacting an outer surface of the rear wheel 14 by using the fixed shaft 324c as a rotating shaft.

In detail, the second rotating drum 324a is formed in a cylindrical shape with the outer surface contacting the rear wheel 14 and rotatably coupled to the fixed shaft 324c.

As the rear wheel 14 is rotated by the user, the second rotating drum 324a rotates using the fixed shaft 324c as the rotation axis.

The load generating means 324b is provided inside the second rotating drum 324a and selectively generates a load for the rotation of the second rotating drum 324a corresponding to the inclination angle of the main frame 100.

Specifically, the load generating means 324b is configured to be rotatable with the fixed shaft 324c in the second rotating drum 324a and is at least partially fixed to the second rotating drum 324a.

When the second rotating drum 324a is rotated by the rear wheel 14, the second rotating drum 324a rotates around the fixed shaft 324c.

Here, the load generating means (324b) is selectively driven by the control unit, in the present embodiment is formed in the form of a disk is fixedly coupled to the inner surface of the second rotating drum (324a).

And the central portion of the load generating means 324b is rotatably coupled to the fixed shaft 324c through a separate bearing.

Accordingly, when the rear wheel 14 is rotated by the external force of the user, the second rotating drum 324a is also rotated together, and the load generating means 324b is selectively driven in response to the inclination angle of the main frame 100. This provides a load for the rotation of the second rotating drum 324a.

At this time, the load generating means 324b is configured to generate a load for relative rotation with the fixed shaft 324c by providing power to a disk generally used.

On the other hand, looking at the configuration of the first rear roller 322, when the main frame 100 is disposed to have a downward slope with a drive motor 322b therein artificially by rotating the first rear roller 322. It is the structure which makes the rear wheel 14 rotate.

In the present invention, the first rear roller 322 largely includes a first rotating drum 322a, a driving motor 322b, and gear means 322c and 322d.

The first rotary drum 322a has a cylindrical shape similar to the second rotary drum 324a described above, and is disposed along the width direction of the rotation support part 310 so that the rear wheel 14 contacts the outer surface. Accordingly, the first rotary drum 322a rotates together when the rear wheel 14 rotates.

The driving motor 322b is provided inside the first rotating drum 322a and is connected to the first rotating drum 322a by the gear means 322c and 322d to rotate the first rotating drum 322a.

Specifically, the driving motor 322b is driven by the control unit when the main frame 100 is inclined downward in the forward direction as described above, and the rotation speed is adjusted to correspond to the inclination angle of the main frame 100.

On the other hand, the gear means (322c, 322d) is provided in the drive motor 322b and the first rotating drum 322a to transfer the rotational force of the drive motor 322b to the first rotating drum (322a) to the first rotating drum Rotate 322a.

Here, the gear means (322c, 322d) is protruded from the surface of the ratchet (322c) and the first rotary drum (322a) provided on the rotation axis of the drive motor (322b), as shown in the selectively ratchet (322c) It includes the engaging member 322d.

In addition, the ratchet 322c and the first rotating drum 322a rotated by the driving motor 322b make relative rotation in one direction.

That is, when the driving motor 322b rotates, the locking member 322d is caught by the gear formed in the ratchet 322c and the first rotating drum 322a is rotated.

On the other hand, when the first rotating drum 322a is rotated by the rotation of the rear wheel 14, and the rotation speed is faster than the rotation speed of the ratchet 322c by the driving motor 322b, the locking member 322d is formed by a ratchet ( 322c is not caught, and the first rotating drum 322a rotates independently of the driving motor 322b.

Accordingly, even when the driving motor 322b does not operate or operates at a relatively slower speed than the rotation speed of the first rotating drum 322a, no load is generated in the driving motor 322b, thereby preventing damage.

That is, the gear means 322c and 322d are means for protecting the driving motor 322b when the first rotating drum 322a and the driving motor 322b rotate, and the rotating shaft and the first rotating drum of the driving motor 322b ( 322a) is configured to rotate relative to one direction.

As such, the first rear roller 322 and the second rear roller 324 according to the present invention are configured, while the user realizes the driving of the slope by tilting the main frame 100 when the user runs, the uphill and the downhill. The acceleration and deceleration of the bicycle by the road can be realized together.

FIG. 10 is a view illustrating a state in which the main frame is inclined upward in the front in the bicycle exercise apparatus of FIG. 4, and FIG. 11 is a view illustrating a state in which the main frame is inclined downward in the front in the bicycle exercise apparatus in FIG. 4. FIG. 11 is a view illustrating a state in which the first rotating drum and the driving motor rotate relative to the rotational speed of the first rotating drum in the first rear roller of the bicycle exercising apparatus of FIG. 11.

First, FIG. 10 is a state in which a bicycle exercise device implements an uphill road, and the main frame 100 is tilted in a clockwise direction by the rotation unit 400.

In this case, the main frame 100 and the rotation support part 310 are in a state where the rotation support part 310 is kept horizontal through relative rotation, and the first rear roller 322 and the first are rotated by the rotation of the rear wheels 14. The two rear rollers 324 rotate clockwise.

Here, the control unit detects the inclination direction and the inclination angle of the main frame 100 and operates the load generating means 324b in response thereto. Accordingly, the second rear roller 324 generates a load for rotation and the rear wheels. Provide a load for the rotation of 14.

At this time, the driving motor 322b provided in the first rear roller 322 is in a non-operating state, and only the first rotating drum 322a is independent of the gear means 322c and 322d according to the rotation of the rear wheels 14. It will be in the state to rotate by.

As described above, the bicycle exercise apparatus according to the present invention becomes a state in which only the load caused by the second rear roller 324 is generated as the main frame 100 is tilted upward to incline forward, thereby implementing a state in which the user travels uphill.

On the other hand, when the main frame 100 is tilted in the counterclockwise direction by the rotation unit 400 to implement the downhill road as shown in Figure 11 is the main frame 100 is disposed to be inclined downward forward The rotary support 310 is rotated relative to the main frame 100 to maintain a horizontal state.

The control unit rotates the first rear roller 322 by detecting the inclination direction and the inclination angle of the main frame 100.

Specifically, the control unit drives the drive motor 322b provided in the first rear roller 322, and the first rotating drum 322a rotates by the rotation of the drive motor 322b to rotate the rear wheels 14. Let's do it.

At this time, since the load generating means 324b does not operate, the second rear roller 324 is in a free rotation state and rotates together with the rear wheels 14.

In general, acceleration occurs on the bicycle by gravity when driving downhill on a bicycle. Similarly, the first rear roller 322 is rotated by the driving motor 322b regardless of an external force by the user. Will be implemented.

Of course, the user may rotate the rear wheel 14 regardless of the rotational speed of the drive motor 322b in the state in which the first rotating drum 322a is rotated by the drive motor 322b.

Specifically, the first rotary drum 322a and the gear means (322c, 322d) is a view showing the rotation speed R1 of the driving motor 322b is greater than the rotation speed R2 of the first rotation drum 322a ratchet ( 322c is engaged with the locking member 322d to rotate the first rotating drum 322a.

On the contrary, when the user rotates the rear wheel 14 at a high speed while the driving motor 322b is rotating, R2 which is the rotational speed of the first rotating drum 322a rather than R1 which is the rotational speed of the driving motor 322b. Becomes relatively larger.

In this case, the gear formed on the ratchet 322c is not caught by the locking member 322d, and the first rotating drum 322a rotates independently.

Accordingly, the user rotates the rear wheels 14 by a constant speed by the driving motor 322b when the main frame 100 is tilted forward and is tilted forward, and the rotational speed of the driving motor 322b is selected by the user. The rear wheels 14 can be rotated more quickly.

In this way, the bicycle exercise apparatus according to the present invention can implement the driving of the ramp more precisely by the first rear roller 322 and the second rear roller 324, so that the user can enjoy the exercise like the actual road driving have.

On the other hand, the bicycle exercise apparatus according to an embodiment of the present invention includes a guide unit.

By being configured to allow the movement according to the direction, the user can implement the effect of driving the actual road.

Meanwhile, the guide unit 500 according to the present invention may further include a safety frame 540 together with the front frame 510, the rear frame 520, and the connection wire part 530.
