The frictional resistance F _fric applied to the bicycle 10 mounted on the bicycle simulator may be proportional to the vertical drag W applied by the rear wheel 12 to the rear wheel roller 50. At this time, the bicycle 10 mounted to the bicycle simulator according to an embodiment of the present invention can reduce the vertical drag by about 40 to 50% than the bicycle 10 mounted to the conventional bicycle simulator, thereby unnecessary frictional resistance The driving reality can be improved by reducing

As described above, when the support point M of the front wheel 14 is the lowest end of the front wheel 14, and the support point N of the rear wheel 12 is also the lowest end of the rear wheel 12, the bicycle mounted on the bicycle simulator ( The frictional resistance (F _fric ) applied to 10 can be minimized. However, the positions of the front wheel 14 and the rear wheel 12 are different according to the size and type of the bicycle 10 to be mounted so that the support point M of the front wheel 14 and the support point N of the rear wheel 12 are the front wheel 14. ) And the lowest end of the rear wheel 12 may not be disposed.

In view of such a problem, in one embodiment of the present invention, the bicycle 10 is mounted on and supported components, for example, the front wheel roller 40, the rear wheel 50 and the frame supported by the support frame 21 As shown in FIGS. 6B and 6C, the support part 30 may be moved relative to the base part 20 along the length direction and the thickness direction of the base part 20, for example, the X-axis direction and the Z-axis direction. . Accordingly, the positions of the front wheel roller 40, the rear wheel roller 50, and the support frame 21 are moved along one direction, for example, the X axis direction or the Z axis direction, depending on the size and type of the bicycle 10 mounted thereon. Thereby, the support point M of the front wheel 14 and the support point N of the rear wheel 12 can be arrange | positioned at the lowest end of the front wheel 14 and the rear wheel 12. FIG. Thus, the lowest end of the front wheel 14 and the lowest end of the rear wheel 12 can be arranged on the same plane, whereby the rider R experiences the same driving condition as driving a substantially flat level and the kinetic energy due to unnecessary frictional force. The loss can be prevented. In addition, the structure disposed below the front wheel roller 40, the rear wheel roller 50 and the support frame 21 can be more easily repaired.

The hydraulic cylinder 610 is connected in fluid communication with the first drive 63, for example, the hydraulic pump, controlled by the control unit 70 so that the pressure of the fluid 614 delivered from the hydraulic pump is one of the piston 612. As a cylinder member that can be transmitted to the end, it is possible to guide the reciprocating movement of the piston 612 while maintaining a closed state with the other end of the piston 612. In this case, at least one elastic member 613 may be provided between the hydraulic cylinder 610 and the piston 612 to elastically support the piston 612 inward with respect to the hydraulic cylinder 610. The elastic member 613 may return the piston 612 downward when the operation of the first driving unit 63 is stopped so that the fluid 614 is not provided into the hydraulic cylinder 610.

The second lifting unit 62 may include a hollow hydraulic cylinder 620, a piston 622, an elastic member 623, and a fluid 624. Since the configuration and operation of the second lift unit 62 are substantially the same as the first lift unit 61, the description is omitted here for convenience.

Accordingly, it is possible to ascend or descend along the front end portion or the Z-axis direction of the base portion 20 supported by the piston 612 provided in the first elevation portion 61. In addition, it is possible to ascend or descend along the rear end of the base portion 20 supported by the piston 622 provided in the second lifting portion 62 or in the Z-axis direction. By raising or lowering the front end or the rear end of the base part 20, the base part 20 can rotate about one axis O, and accordingly, the base of the bike 10 mounted on the bike simulator 1 can be rotated. The inclination angle δ can be adjusted.

In the following, by adjusting the inclination angle δ of the bicycle 10 mounted on the bicycle simulator 1 in conjunction with the display device 75, it is possible to experience various driving conditions not only visually but also the whole body, The bicycle simulator 1, which can enjoy dynamic and exciting riding in an indoor space, will be described in more detail.

For example, when the input unit 76 inputs an input signal by a voice input method, even when the rider R is visually impaired, or when the two hands of the rider R are fixed to the handle and the hand cannot be used. The input signal related to the driving mode may be transmitted to the controller 70.

The display apparatus 75 may visually provide the rider R with a predetermined driving environment having an inclined portion according to the driving mode selected by the rider R. For example, the display device 75 may display an actual mountain driving path input by the rider R. Accordingly, the rider R can visually experience various driving states having the inclination angle δ.

The controller 70 may apply a driving force to at least one of the first lifting unit 61 or the second lifting unit by using the first driving unit 63. As an example, the controller 70 may recognize the driving state implemented in the display apparatus 75 and then manipulate the first driving unit 63 to correspond to the driving situation.
