Description

Virtual surface-implemented bicycle simulator

The present invention relates to a virtual road-implemented bicycle simulator, and more particularly, to a bicycle simulator capable of virtually experiencing various road surfaces such as general pavement roads, unpaved forest roads and mountain roads in an indoor space.

Bicycle trainers, generally called bicycle trainers or bicycle rollers, are the most widely used fitness equipment for indoor workouts with treadmills. The lower body muscle strength is enhanced by rotating the applied wheel.

Such a conventional bicycle exercise equipment has an advantage that can provide a fairly high exercise effect to the rider with only a relatively short time of movement through the adjustment of the rotational resistance applied to the wheel regardless of the weather.

However, since the conventional bicycle exercise equipment only sustains the pedaling exercise applied with rotational resistance while facing the wall in the enclosed indoor space, it is free or tired of not providing the rider with the pleasure of riding the bicycle at all. Due to the difficulty of continuing the continuous pedaling exercise.

In order to improve the above problems, Korean Patent Registration No. 10-1677713 (Date: 2016.11.23) discloses a technique relating to a cycle exercise device.

For convenience of explanation, the relative positions between the drawings and the configurations are set as a reference, and each direction described below is based on this, except where specifically defined otherwise.

In the virtual road-implemented bicycle simulator 100 according to the present invention, the rider R riding on the bicycle 10 basically has various impact characteristics corresponding to various road conditions such as general pavement, unpaved road, mountain road, and the like. It is an invention devised in order to be able to virtually experience a realistic ride by receiving from the wheels (front wheel 14 and rear wheel 12) of (10).

Furthermore, the present invention, through the application of the electric control method using a magnetic force rather than the mechanical operation method using the pressure of the fluid, the simultaneous and individual operation control for a plurality of uneven parts 122 protruding to implement the road surface is less The number of parts and a simple structure make it easy to achieve low noise and high power without any special impact, thereby facilitating the compactness and fabrication of the bicycle simulator 100 and its maintenance and compactness.

The above-mentioned bicycle 10 is not only specially manufactured for the virtual road-implemented bicycle simulator 100 according to the present invention, but also encompasses all of the bicycles 10 currently available from various bicycle manufacturers. It is a concept. The bicycle 10, the bicycle frame 11 constituting the body of the bicycle 10, the front wheel 14 and the rear wheel 12 is rotatably mounted to the bicycle frame 11, and the pedaling of the rider (R) It includes a drive system (crank, chain, transmission, etc.) for converting the to the rotational force of the rear wheel (12).

The virtual road-implemented bicycle simulator 100 according to the present invention may include a rear wheel support 110 and a road surface implementer 120 to implement the functions or functions as described above.

Hereinafter, each configuration described above will be described in detail.

First, the rear wheel support unit 110 is opposed by the rear wheel 12 that rotates in one direction according to the pedaling of the rider R while supporting the rear wheel 12 of the bicycle 10 mounted on the bicycle simulator 100. As a component that rotates in the direction, both ends are coupled to the base frame 102 of the bicycle simulator 100 so as to freely rotate forward or backward.

The overall shape of the rear wheel support 110 may be any shape as long as it can rotate together with the rotation of the rear wheels 12 while being in contact with the rear wheels 12, and thus the longitudinal section thereof may be polygonal, oval or circular. Can be.

However, the rear wheel support 110 according to the present invention, the circular longitudinal cross section so that the smooth rotation according to the rotation of the rear wheel 12 can be made without providing a heterogeneous driving feeling to the rider R for rotating the rear wheel 12. 1 to 5, but may be configured to include a shaft 112, a cylindrical frame 114, and a plurality of surface holes 116, and the like.

The shaft 112 is a hollow 112a-type pipe, and both ends thereof are fixed to the base frame 102 of the bicycle simulator 100 to function as a fixed shaft of the rear wheel support 110.

The cylindrical frame 114 is a cylindrical component that is in direct contact with the rear wheels 12 and rotates together with the rotation of the rear wheels 12, and both ends thereof are penetrated by the fixed shaft 112. It is axially coupled to rotate relative to.

At this time, various shaft coupling means such as a bearing 113 may be used to freely rotate the cylindrical frame 114 relative to the fixed shaft 112.

Specifically, the shaft coupling of the cylindrical frame 114 to the shaft 112 is, as shown in Figures 4 and 5, the outer ring of the radial ball bearing used when the load in the direction perpendicular to the rotation axis direction is cylindrical It is fixed to both ends of the frame 114, the inner ring of the radial ball bearing is made by being inserted through the shaft 112 and then fixed.

Further, unlike shown, the axial coupling of the cylindrical frame 114 to the shaft 112 is relative to the cylindrical frame 114 disposed in a penetrated state by the shaft 112 fixed to the base frame 102. The outer ring of the radial ball bearing is fixedly installed on the base frame 102, and the inner ring of the radial bearing is penetrated after being penetrated by both ends of the cylindrical frame 114, it may be made, it can be made in addition to the various methods as well to be.

The shaft coupling means (bearing 113) is interposed between the fixed shaft 112 and the cylindrical frame 114 in the above manner, so that the cylindrical frame 114 firmly supports the load by the rear wheels and the like and is attached to the shaft 112. Relative free rotation.

The cylindrical frame 114 itself is a concrete pavement, asphalt pavement, velodum (not shown) if the uneven portion 122 to be described later does not protrude outward (see Fig. 7a), the direct contact with the rear wheel 12 ( It gives the rider a feeling of a flat road surface, such as a velodrome track.

The surface hole 116 is a component provided to allow protrusions and protrusions 122 to be described later from the inside of the rear wheel support 110 to the outside, and the entire outer circumferential surface of the cylindrical frame 114 or the rear wheel 12. A plurality of through-holes may be formed along a portion of the outer circumferential surface which comes into contact with each other.

The concave-convex portion 122 provided in the shape corresponding to the size and number of the surface holes 116, the arrangement interval, and the like, and the protrusions 122, is a kind of virtual road surface to be implemented (muddy road, dirt road, sand road, etc.) Of course, it can be variously modified according to a mountain road made of coarse gravel or stone.

Although not shown, the rear wheel support unit 110 according to the present invention may be configured as two rear wheel support units 110 that rotate and support forward and backward from the lower side of the rear wheel 12 for stable support of the rear wheel 12.

The road surface implementing unit 120 provides the rider R pedaling various types of impact characteristics transmitted to the rear wheel 12 (and the front wheel 14) according to road conditions such as general pavement, unpaved road, mountain road, and the like. As a technical feature of the present invention provided only for this, this allows the rider R to experience a dynamic and realistic riding that could not be felt in a general cylindrical roller.

The road surface implementation unit 120 as described above may be implemented through a plurality of uneven parts 122 configured to protrude from the outer circumferential surface of the rear wheel support 110 in contact with the rear wheels 12 at various heights. The variable protruding operation, i.e., the reciprocating motion is performed by the electric driving method utilizing the controlled magnetic force, not the mechanical driving method using the pressure of the fluid or the rotational force of the motor.

The reason why the electric driving method is adopted is a mechanical driving method utilizing the pressure of the fluid, and various problems that occur when implementing various protrusion operations of each of the uneven parts 122 (that is, a large amount compared to the electric driving method). Surface parts 120 by improving or eliminating demands (e.g., a plurality of cylinders (pipes), valves, rotary joints, etc.), and difficulty in connecting or coupling parts for transmitting driving force, etc.) It is to make compact modularization of low power and high output with ease of manufacture and maintenance.

In order to solve the problems occurring in the mechanical driving method with the implementation of the above functions or operations, the road surface implementation portion 120 according to the first embodiment of the present invention, the uneven portion 122 and the magnetic force generation portion 124 ) And the like.

The uneven part 122 is a cylinder projecting from the inside of the cylindrical frame 114 to provide the rider R with a feeling of a rough road surface such as an unpaved road or a mountain road made of coarse sand or gravel (see FIG. 7B). As a component that rotates together with the frame 114, the first magnet 122a, the protrusion 122b, and the like are configured.

The first magnet 122a is made of a commercially available magnet in which the N pole and the S pole are magnetized on one side and the other side, respectively, and a plate-like structure in which magnetic force (human or repulsive force) is exerted by the operation of the magnetic force generation unit 124 to be described later. As an element, it is provided reciprocally in a state where separation is prevented by the housing 121 coupled to the inner side of the cylindrical frame 114.

The first magnet 122a is not particularly limited as long as it is a commercially available thin-walled magnet capable of reciprocating due to magnetic force (human or repulsive force) according to the operation of the magnetic force generating unit 124. It is preferable to use a magnet of neodymium (ND) material so that a strong magnetic force in the relationship with 124).

The protrusion 122b has a rod-like configuration that protrudes through the surface hole 116 according to a controlled magnetic force (human or repulsive force) acting between the first magnet 122a and the magnetic force generating unit 124 described above. As an element, at least one of the first magnets 122a is provided on the opposite side of the magnetic force generating unit 124 to be described later to form the uneven portion 122.

The protrusion 122b that protrudes through the surface hole 116 and implements the road surface state may be combined with one first magnet 122a as one embodiment as shown in FIG. 5.

And the protrusion 122b is integrated in a state in which two or more (for example, three) are arranged side by side along the longitudinal direction of the rear wheel support 110 as shown in the third embodiment shown in FIG. It can be combined with the (122a), to group the two or more projections (122b) to facilitate the ease of manufacturing and control of the uneven portion 122.

Concave-convex portion 122 of the above structure, a plurality of the cylindrical frame 114 may be regularly spaced apart as shown in FIGS. 3 and 4 or irregularly spaced apart from the illustrated.

Furthermore, in order to modularize the road surface implementing unit 120 in various forms, the number of the uneven parts 122, the size of the protrusions 122b, the arrangement intervals, the integration of the protrusions 122b, etc. may be changed differently and appropriately combined. Of course it can.

That is, the uneven portion 122 increases the size of the protrusion 122b while reducing the number of the uneven portions 122 in order to transmit a feeling similar to gravel to the rider R, while the protrusion 122b has The spacing can be wide.

In addition, the concave-convex portion 122 reduces the size of the protrusion 122b while increasing the number of the concave-convex portion 122 in order to transmit a feeling similar to sand to the rider R, while disposing the protrusion 122b. It can form a narrow gap.

Thus, the irregularities 122 formed in different forms or combinations are variously modularized into the road surface implementing portion 120, so that the rider R is gravel (when a large protrusion 122b protrudes) or sand (size As well as the feeling of the road surface consisting of a small protrusion (122b) protrudes, as well as a road surface mixed with gravel and sand (the uneven portion 122 is composed of a combination of a large protrusion 122b and a small protrusion 122b) all protrude Can be selectively experienced.

Meanwhile, at least one elastic body 123 may be provided between the cylindrical frame 114 and the uneven part 122 to elastically support the uneven part 122 toward the inside of the cylindrical frame 114 (not protruding). have.

In the elastic body 123, when the control power is not applied to the electromagnets 124a, 124a1, and 124a2 to be described later, the magnetic force is not applied to the first magnet 122a, etc. This is to automatically receive the inside of the cylindrical frame 114 does not protrude.

Here, the magnetic force generation unit 124 is a component that is fixed to the shaft 112 to generate a controlled magnetic force so that the protrusion 122b protrudes to various heights by the action of the magnetic force on the first magnet 122a. And an electromagnet 124a, a lead wire 124b, a controller 125, and the like.

The electromagnet 124a is a component that generates a magnetic force corresponding to the magnitude in a fixed direction when a predetermined control power is applied from the control unit 125 to be described later through the corresponding lead wires 124a, 124a1, and 124a2.

A plurality of such electromagnets 124a are installed on the outer circumferential surface of the shaft 112 facing the first magnet 122a described above, and the first magnet 122a of the uneven portion 122 that rotates together with the cylindrical frame 114. Each of which produces a controlled magnetic force.

That is, each of the electromagnets 124a continuously generating a controlled magnetic force in the direction of each magnetic force divergence while being fixed to the shaft 112 may be rotated and positioned in the influence of the magnetic force. The repulsive force acts on the first magnet 122a to protrude the protrusion 122b to various heights (see FIG. 7B).

On the other hand, when the electromagnet 124a does not receive a predetermined control power from the control unit 125 through the corresponding lead wires 124a, 124a1, and 124a2, the magnetic force is immediately lost, which rotates and is located within the influence of the magnetic force. No force is applied to the first magnets 122a of the uneven parts 122 to be suppressed, so that the protrusion of the protrusions 122b is suppressed (see FIG. 7A).

The electromagnet 124a operating as described above is basically made of a magnetic core made of a ferromagnetic material and a coil wound repeatedly around the core. Since the specific structure and the principle of generating magnetic force, polarity, and strength are already known techniques, Detailed description thereof will be omitted.

However, the electromagnet 124a according to the present invention has a plurality of compactly installed along the outer circumferential surface of the shaft 112 located inside the cylindrical frame 114 provided with the protrusions and protrusions 122 (approximately 4 cm in and around diameter). It is desirable to use a miniaturized commercial product that can generate a magnetic force (approximately around 50 kg (500 N) or so) of strength that can be applied to and can firmly support the load applied directly from the rear wheel 12 (or front wheel 14). Do.

As shown in FIGS. 4 and 5, the electromagnet 124a is irregularly spaced apart or irregularly arranged along the outer circumferential surface of the shaft 112 corresponding to the region where the uneven portion 122 is provided. Can be spaced apart.

At this time, the electromagnet 124a is installed so that the diverging surface generating the magnetic force faces the first magnet 122a of the uneven portion 122.

In this way, the plurality of electromagnets 124a installed to face the first magnets 122a of the uneven parts 122 have a shape that tightly surrounds the entire circumference of the outer circumferential surface of the shaft 112 as in the first embodiment shown in FIG. 5. Can be installed.

In addition, the plurality of electromagnets 124a, as shown in the second embodiment shown in Figure 6a can be installed in a plurality of densely in the form defined in the upper outer peripheral surface of the shaft 112, which is the protrusion operation of the protrusion (122b) This is to be made only at the upper end of the rear wheel support 110 in contact with (12). As a result, the number of the required electromagnets 124a is reduced, so that the road surface implementing unit 120 can be configured simply and efficiently.

In addition, the plurality of electromagnets 124a correspond to the uneven parts 122 formed by coupling one first magnet 122a to three protrusions 122b integrated as in the third embodiment shown in FIG. 6B. By being spaced apart by a number, it is possible to achieve the conciseness and efficiency of the road surface implementing unit 120 as shown in FIG. 6A.

The controller 125 is a component provided to allow various protrusion operations of the protrusions 122b corresponding to various road surfaces which are virtually set, and is electrically connected to the respective electromagnets 124a through the lead wires 124b. By applying the control power of various sizes that are individualized, the degree of protrusion of the uneven portion 122 is freely varied. (See FIGS. 7A and 7B.)

In addition, the controller 125 is connected to various devices to be described later to receive predetermined data and perform control operations based thereon.

The controller 125 may be implemented as a modular unit such as a micro controller unit (MCU), a microcomputer, an Arduino, or the like, and a memory (not shown) may be provided therein.

The memory is implemented as a hard disk drive (Hard Disk Drive, HDD), ROM (Read Only Memory), random access memory (RAM), flash memory (Flash Memory) or a memory card (Memory Card), etc. An operating system program for operating the 100 and data necessary for the same may be stored.

In this case, the necessary data may include image information (including road state information) or driving information for each rider R, which is data of various bicycle competition courses or a driving environment for a specific region through 3D mapping technology.

A series of processes of the controller 125 for controlling each connected device and processing or storing the received data is performed by coding in a programming language such as a machine language.

Specific implementation and control method of the control unit 125 can be easily made in various ways and forms at the level of those skilled in the art, the detailed description thereof will be omitted.

As described above, the rider R may virtually experience realistic riding due to the road surface implementing unit 120 performing the protrusion operation of the uneven portion 122 based on a non-contact magnetic force. Each of the plurality of protrusions and protrusions 122 protruding for realizing a road surface can be easily operated and controlled individually.

Furthermore, due to the simplification and simplification of the number of parts for the realization of the road surface realization part 120 and the minimization of the direct impact between parts for the protrusion operation of the uneven part 122, the bicycle simulator 100 according to the present invention is low noise and high power. In operation, the durability of the bicycle simulator 100, the ease of manufacture and maintenance, and the compact modularity can be easily achieved.

Meanwhile, the road surface implementing unit 120 according to the fourth embodiment of the present invention is conceived for realizing not only various road surfaces according to the first embodiment of the present invention, but also road surfaces such as Cobblestone. It may be configured to include a frame 126, concave-convex portion 122 and the magnetic force generating portion 124.

The outer frame 126 here is engaged with one or more second magnets 126a provided reciprocally inside the cylindrical frame 114 to protrude from the cylindrical frame 114 and correspond to the surface hole 116. One or more split frames having through holes 126c (however, in FIGS. 6C and 7C, the split frames 126b-1 to 126b-4 are configured).

According to the outer frame 126 that protrudes in this way, when the uneven portion 122 and the outer frame 126 itself do not protrude outwardly (see FIG. 6C), the concrete pavement road is directly contacted with the rear wheel 12.
