Description

Bicycle Simulator {Bicycle Simulator}

The present invention relates to a bicycle simulator for virtual driving, and more particularly, to a bicycle simulator capable of virtually experiencing various driving routes in an indoor space and enjoying exercise effects.

Bicycle exercise equipment, commonly referred to as a bicycle trainer or bicycle roller, is the most widely used indoor exercise fitness equipment along with a treadmill, and a rider riding a bicycle seated on a rotating roller or cradle uses a pedal to reduce rotational resistance ( Magnetic force, etc.) is applied to rotate the wheel, which aims to strengthen the lower body muscle strength.

Such conventional bicycle exercise equipment has the advantage of being able to provide a considerably high exercise effect to the rider with only a relatively short exercise time through adjustment of the rotation resistance applied to the wheel regardless of the weather.

However, since the conventional bicycle exercise equipment continues only the pedaling exercise to which the rotational resistance is applied while facing the wall in an enclosed indoor space, it does not provide the rider with the pleasure of riding a bicycle at all, resulting in boredom or boredom. Due to this, there was a problem that it was difficult to continue pedaling exercise with continuity.

In order to improve the above problems, Prior Art 1 (Korean Patent Registration No. 10-1677713) and Prior Art 2 (Korean Patent Registration No. 10-1827306) disclose a technique related to a cycle exercise device.

In the prior art 1, by replacing three or more roller parts that rotate about a fixed axis (central axis) and have different outer wall shapes, it is possible to provide riders with a driving experience for various road conditions similar to actual bicycle riding, , there is an advantage in that the rider can continue the pedaling exercise with continuity through the arousal of interest. However, the cycle exercise mechanism proposed in Prior Art 1 rotates three or more roller parts back and forth, and due to implementing various road surfaces, the structure is complicated, so manufacturing or maintenance difficulties are expected, and the roller parts are rotated to change the road surface In this case, the pedaling bicycle itself has no choice but to move greatly in the vertical direction, greatly impairing the safety of the rider riding the bicycle, and there is a problem in that the natural change of the road surface cannot be implemented.

In the prior art 2, since the concavo-convex part capable of realizing a virtual road surface protrudes along the roller part, a safer driving experience and natural change of the road surface can be provided to the rider. However, the cycle exercise device proposed in Prior Art 2 only implements a flat virtual road surface, but has a problem in that it does not implement various driving modes according to the type of rider and the actual driving environment having an incline.
