More specifically, the present invention relates to a wheelchair simulation system, and more specifically, by providing a simulation effect like actually driving in a wheelchair in various usage environments, it is possible to improve not only the exercise ability of the wheelchair user but also various abilities required by the user, such as driving ability and usage experience. This is about a wheelchair simulation system that can be comprehensively improved.

In general, a wheelchair refers to a chair with wheels made for people who have difficulty walking normally, such as people with physical disabilities or leg problems, to sit on a chair and move around.

Wheelchair users need periodic exercise for rehabilitation or health promotion, and the need for exercise is especially great in the case of manual wheelchairs that are driven only by the user's arm strength.

Accordingly, various wheelchair exercise devices have been proposed in the past to exercise the arms of wheelchair users. Most of them include a pair of rollers that support the wheelchair wheels so that they can rotate in place, and are configured to allow the user to obtain exercise effects by rotating the wheels in place. It is done.

However, since these conventional wheelchair exercise devices are configured to simply rotate the wheelchair wheels in place, they have the limitation of not providing any positive effects other than the arm exercise effect to the user.

In other words, wheelchair users must drive their wheelchairs in various environments, so they need various abilities related to driving, such as the motor ability to rotate the wheels, the ability to drive efficiently for efficient driving, and the ability to respond to unexpected situations. In addition to its function as a simple exercise device, it has limitations in that it cannot provide any effect that can improve the driving ability or usage experience of wheelchair users.

In addition, the conventional device simply consists of rotating the wheel for exercise, so the user does not feel any fun or interest, and as a result, they become bored or avoid using it, making it difficult to exercise efficiently.

In addition, since the conventional device has a pair of rollers fixed at a certain distance apart so that the wheelchair wheels can be sandwiched between them, an impact is bound to occur when the wheel is seated between the pair of rollers. In addition to causing discomfort and anxiety to users, there are also limitations that can cause device damage.

The present invention provides wheelchair users with a simulation effect similar to actually driving in a wheelchair in various usage environments, thereby efficiently improving the driving ability and usage experience of wheelchair users and enabling safer and more convenient use. This relates to a wheelchair simulation system that can provide stability and convenience to users.

For this purpose, a wheelchair simulation system according to the first embodiment of the present invention is illustrated in FIGS. 1 to 6.

As illustrated in Figures 1 and 2, the wheelchair simulation system according to the first embodiment of the present invention includes a main body frame 100, a wheel rotation unit 200, a display unit 300, and a simulation control unit ( 400).

First, the main body frame 100 may have a physical structure that allows entry and exit of the wheelchair C.

In other words, the wheelchair (C), which is the object of the simulation experience, enters and exits the main body frame 100, and the wheelchair (C) enters the main frame 100 and is positioned in the wheel rotation unit 200, which will be described later. , After the simulation experience, you can escape from the main body frame 100.

As illustrated in FIG. 3 , the main body frame 100 may include, for example, a pair of left and right guideways 110 that guide both wheels (w) of the wheelchair (C) to travel.

In addition, each of the pair of guide paths 110 may be provided with an inclined surface 120 that slopes upward at a certain angle toward the rear.

The wheelchair (C) can enter the main body frame 100 by having both wheels (w) drive backwards along a pair of guideways 110, and drive forward along the pair of guideways 110 to enter the main body frame. You can escape from (100).

Next, the wheel rotation unit 200 supports the wheelchair C so that the wheels w can be rotated in place, and can perform the function of exchanging information with the simulation control unit 400, which will be described later.

As illustrated in Figure 3, the wheel rotation unit 200 is provided on the main body frame 100, for example, it may be provided on the rear side of the pair of guides 110.

In other words, the wheel rotation unit 200 may also be composed of a pair of left and right wheels corresponding to the left and right wheels (w) of the wheelchair (C), and the pair of wheel rotation units (200) are provided at the rear of each pair of left and right guides (110). They can be arranged side by side.

This wheel rotation unit 200 supports the wheels (w) of the wheelchair (C) so that they can rotate in place, and for this purpose, it may basically include a main roller (210) and a sub-roller (220).

As illustrated in FIGS. 3 and 4, the main roller 210 is provided on the front side to be connected to the rear end of the guideway 110, and the sub-roller 220 is spaced a certain distance from the main roller 210 to form the main roller 210. It may be provided on the rear side of the roller 210.

Accordingly, as illustrated in FIGS. 5 and 6, the lower portion of the wheel w of the wheelchair C may be inserted and supported between the main roller 210 and the sub roller 220. That is, the main roller 210 supports the lower front side of the wheel w, and the sub-roller 220 supports the lower rear side of the wheel w.

In this way, the lower part of the wheel (w) is inserted between the main roller 210 and the sub-roller 220 and supported between the main roller 210 and the sub-roller 220, and the wheel (w) does not move in position. It can be rotated in place as it is supported.

In addition, the wheel rotation unit 200 further includes a roller controller 230 that transmits rotation information of the wheel (w) through two-way communication with the simulation control unit 400, receives load information, and applies a load to the wheel (w). It can be included.

This roller controller 230 may be coupled to the main roller 210 and obtain rotation information of the wheel w through the coupled main roller 210 and apply a load to the wheel w. there is.

That is, when the user manually rotates the wheel (w) using his or her hand, the main roller 210 rotates in conjunction with this, so the roller controller 230 rotates the wheel (w) according to the rotation of the main roller 210. Information can be acquired and this rotation information can be provided to the simulation control unit 400, which will be described later.

In addition, when the load information provided from the simulation control unit 400 is received, the main roller 210 is forcibly driven in a direction to manually limit or accelerate the rotation of the wheel w, thereby driving the wheel w of the wheel chair C. ) can be applied to a certain load.

For example, the roller controller 230 that performs the above functions may be implemented as a servo motor with excellent speed control and torque control characteristics.

Next, the display unit 300 is a part that outputs a simulation image related to the driving of the wheelchair C.

That is, the display unit 300 is controlled by the simulation control unit 400, which will be described later, and can provide the user with images similar to actually driving in a wheelchair C in various usage environments.

For example, when the wheelchair (C) is positioned in the wheel rotation unit 200 and the user rotates both wheels (w) equally, the display unit 300 actually displays a specific space according to the rotation of the wheels (w). An image of moving in a straight line can be output in real time, and if both wheels (w) are rotated differently, an image of the driving direction changing can be output on the display unit 300.

The simulation image output to the display unit 300 is not particularly limited, and may include not only images of driving in various environments but also game images, etc.

As illustrated in FIG. 2, the display unit 300 is implemented in the form of a stand-type monitor and can be installed in a position where the user can directly view it while manipulating the wheels (w) of the wheelchair (C). There is no need to be limited, and it may also be possible to implement it in the form of goggles worn on the head so that the output image can be felt more realistically.

Next, the simulation control unit 400 can perform comprehensive control to link the actual rotation of the wheel chair wheel (w) located in the wheel rotation unit 200 with the simulation image output to the display unit 300. .

That is, the simulation control unit 400 receives rotation information of the wheel (w) provided from the wheel rotation unit 200, and receives driving information of the wheelchair (C) including driving speed, driving direction, driving path, etc. from this rotation information. can be calculated, and the simulation image output to the display unit can be controlled according to this driving information.

For example, when the user rotates both wheels (w) equally for driving straight, this rotation information of both wheels (w) is provided from the wheel rotation unit 200 to the simulation control unit 400, and the simulation The control unit 400 can control the output image of the display unit 300 by calculating the driving speed from this rotation information and determining that the driving speed is straight.

That is, an image of driving straight at the calculated driving speed is output to the display unit 300 under the control of the simulation control unit 400.

In addition, when the user rotates both wheels (w) differently to change the driving direction, this rotation information of both wheels (w) is provided to the simulation control unit 400, and the simulation control unit 400 controls the rotation. The output image of the display unit 300 can be controlled by determining the change in driving direction, change angle, etc. from the information.

That is, under the control of the simulation control unit 400, an image showing the driving direction changing by a certain angle and turning right or left is output to the display unit 300.

In addition, the simulation control unit 400 provides load information according to the event in the simulation image to the wheel rotation unit 200 so that an appropriate load according to the event can be applied to the wheels (w) of the wheelchair (C). ) can be controlled.

Here, the event refers to various factors that can exist on the driving path and affect the operation of the wheelchair (C) and wheels (w), such as uphill, downhill, unpaved roads, speed bumps, and collisions due to deviation from the path in the simulation video. It can mean.

For example, when an uphill event occurs, the simulation control unit 400 calculates the load to be applied to the wheels (w) of the wheelchair (C) according to the uphill slope and provides the load information to the wheel rotation unit 200, and the wheel rotation unit ( The roller controller 230 of 200) can drive the main roller 210 to apply a torque that limits the rotation of the wheels (w) of the wheelchair (C).

Accordingly, the user must apply more force to rotate the wheels (w) of the wheelchair (C) than when driving on a flat surface, so that the user can experience the same feeling as actually driving uphill.

When a downhill event occurs, contrary to the above, under the control of the simulation control unit 400, the roller controller 230 can drive the main roller 210 so that torque is applied in a direction that forcibly rotates the wheels (w) of the wheelchair (C). Accordingly, the user can experience the same feeling as actually driving downhill.

In addition, when an unpaved road event with uneven road surface conditions such as unevenness occurs, the simulation control unit 400 controls the roller controller 230 so that both main rollers 210 apply different torques to each wheel w. Accordingly, users can experience the same feeling as driving on an actual unpaved road.

In addition, when a collision event occurs, the simulation control unit 400 can control the roller controller 230 so that a strong torque is applied to the wheels (w) of the wheelchair (C) for a short moment, and accordingly, the user can compare the difference between actually colliding with an object and Experiences can be achieved by feeling the same way.

As above, the simulation control unit 400 not only receives information from the wheel rotation unit 200 to control the simulation image, but also transmits and controls information to the wheel rotation unit 200 according to events in the simulation image, that is, wheel rotation. Two-way communication is established with the unit 200.

Meanwhile, in this embodiment, as illustrated in FIG. 1, it may further include a simulation storage unit 500 that stores various simulation programs and a user setting unit 600 that can receive settings from the user. there is.

Various simulation programs can be stored in the simulation storage unit 500. For example, various simulation programs depending on driving difficulty may be stored, ranging from simulations with courses that beginners can easily drive to simulations with complex driving courses that are difficult for even experienced users to drive. In addition, various simulation programs may be stored depending on driving difficulty, such as urban areas, trails, etc. Simulation programs that allow users to experience various environments, such as riversides, may be stored, and game programs that users can enjoy may also be stored.

The user setting unit 600 may receive input from the user for selecting a simulation program to be executed among various simulation programs stored in the simulation storage unit 500.

In other words, the wheelchair user can appropriately select and input the simulation program he or she wants to experience through the user setting unit 600 according to his or her preference or skill in using the wheelchair.

When a selection input is made by the user through the user setting unit 600, the simulation control unit 400 executes the specific simulation program selected and entered by the user among various stored simulation programs so that the corresponding simulation image is displayed on the display unit 300. You can control it.

The user setting unit 600 is installed at an appropriate position on the main body frame 100 so that the user seated in the wheelchair C can easily input when the wheelchair C is located in the wheel rotation unit 200. It can be implemented as a touch panel, for example.

In addition, the user setting unit 600 can of course be implemented in the form of an application installed on a smartphone carried by the user.

As the wheelchair simulation system according to the first embodiment of the present invention has been described above, the use and operation of this wheelchair simulation system will be briefly reviewed below.

First, while riding the wheelchair (C), the user drives along the left and right pair of guideways (110) to enter the main body frame (100), and then both wheels (w) are connected to the wheel rotation units (200) on both left and right sides. Make sure it is seated and supported.

That is, as illustrated in FIGS. 5 and 6, the wheels (w) of the wheelchair (C) are seated between the main roller 210 and the sub-roller 220 of both wheel rotation units 200, allowing rotation in place. keep it supported.

Next, when the user selects and inputs a simulation program to experience through the user setting unit 600, the simulation control unit 400 executes the corresponding simulation program, and under the control of the simulation control unit 400, the display unit 300 displays the program. The corresponding simulation video is output.

Then, the user begins the simulation experience by rotating both wheels w according to the driving course in the image while watching the simulation image displayed on the display unit 300.

At this time, when the wheel (w) is rotated by the user's manipulation, the main roller 210 rotates accordingly, and the rotation information of the wheel (w) is provided to the simulation control unit 400 through the roller controller 230. do.

Then, the simulation control unit 400 calculates driving information of the wheelchair (C), such as speed and direction, from the rotation information of both wheels (w) provided by the roller controller 230, and displays the simulation image output on the display unit 300 in real time. Control.

For example, when both wheels (w) rotate at the same speed, the display unit 300 outputs an image of straight driving at the corresponding speed, and when both wheels (w) rotate at different speeds, an image of the direction changing is output. It can be.

Meanwhile, if an event such as uphill, downhill, uneven, collision, etc. occurs during the above simulation process, the simulation control unit 400 transmits load information according to the event to the wheel rotation unit 200 and sends the wheelchair (C) wheel (w) to the wheel rotation unit (200). ) The roller controller 230 is controlled so that an appropriate load is applied.

Therefore, in addition to the exercise effect that can be obtained by simply rotating the wheel (w) of the wheelchair (C), the user is provided with a simulation effect such as actually driving in a wheelchair (C) in various usage environments, making it more fun and interesting. In addition to being able to feel and have a pleasant experience, you can also achieve the effect of efficiently improving your wheelchair usage ability and usage experience.

Meanwhile, Figures 7 to 11 illustrate a second embodiment of the present invention.

The second embodiment of the present invention has the same overall configuration as the first embodiment described above, but there is a difference in the configuration of the wheel rotation unit 200.

Therefore, in the following description of the second embodiment, the same symbols as the above-described first embodiment will be used for the same components, and overlapping detailed description will be omitted, and the different components will be described with reference to FIGS. 7 to 11. We will focus on explaining only this.

The wheel rotation unit 200 according to the second embodiment includes a main roller 210, a sub-roller 220, and a roller controller 230 in the same manner as the first embodiment described above. Unlike, the position of the sub-roller 220 is not fixed and can be horizontally moved forward and backward.

In addition, the wheel rotation unit 200 includes a displacement driving means 240 that provides a horizontal moving force to the sub-roller 220, and a roller displacement control unit (not shown) that controls the operation of the displacement driving means 240. It may be further included.

That is, in this second embodiment, the sub-roller 220 is not fixed in position but is capable of horizontal movement forward and backward, and thus can be moved forward and positioned close to the main roller 210. It can be moved backward and positioned at a certain distance away from the main roller 210 (i.e., the position of the sub-roller 220 in the first embodiment).

As illustrated in FIG. 7, in order to move the sub-roller 220 forward and backward, there are sliders 221 at both ends of the sub-roller 220 that rotatably support the sub-roller 220, and the slider ( As 221) slides, a guide rail 222 may be formed to guide it to move forward and backward.

That is, the sub-roller 220 is rotatably supported by the sliders 221 at both ends and can move forward and backward in a straight line as the slider 221 slides along the guide rail 222.

The displacement driving means 240 may provide a horizontal movement force to the sub-roller 220 so that the sub-roller 220, which is provided to be horizontally movable as described above, can move forward and backward.

That is, the sub-roller 220 may be moved forward to a position close to the main roller 210 according to the operation of the displacement driving means 240, or may be moved backward to a position away from the main roller 210. .

This displacement driving means 240 may be implemented, for example, as a hydraulic cylinder that reciprocates the cylinder rod 241, and the cylinder rod 241 is connected to the slider 221 and the connecting bar 242 at both ends of the sub-roller 220. ), the slider 221 can be moved forward and backward according to the reciprocating movement of the cylinder rod 241.

The roller displacement control unit controls the operation of the displacement driving means 240. As illustrated in FIG. 8, the sub-roller 220 is in the initial state before the wheelchair C is located in the wheel rotation unit 200. The displacement driving means 240 can be controlled to be positioned close to the main roller 210.

That is, in the state (initial state) before the user enters the main body frame 100 in the wheelchair (C), the displacement driving means 240 is used so that the sub roller 220 moves forward and is positioned close to the main roller 210. It's about controlling.

And in this state, for the simulation experience, when the wheelchair (C) enters the main body frame (100) and the wheels (w) are placed on the main roller (210) and sub-roller (220) that are close to each other, the roller displacement control unit The displacement driving means 240 can be controlled so that the roller 220 moves backward and is spaced apart from the main roller 210.

That is, as illustrated in FIG. 9, when the wheels (w) of the wheelchair (C) are positioned so as to contact the main rollers (210) and sub-rollers (220) that are close to each other and the first position setting is achieved, FIGs. As illustrated in FIG. 11, the roller displacement control unit drives the displacement so that secondary position setting can be achieved by supporting the wheel (w) between the main roller 210 and the sub-roller 220, which are spaced apart from each other, so that it can rotate in place. The means 240 is controlled to move the sub-roller 220 backward.

According to the control of this displacement controller unit, the sub-roller 220 is initially in contact with the wheel w while positioned close to the main roller 210, and then the wheel w is positioned between the main roller 210. The backward movement is made so that it is supported so that it can rotate in place, and at this time, the sub-roller 220 moves backward while continuously maintaining contact with the wheel (w).

In other words, the process in which the wheels (w) of the wheelchair (C) are seated and supported on the wheel rotation unit (200) is first, as illustrated in FIG. 9, the wheels (w) are close to each other, the main roller (210) and the sub-roller. (220) In the first position setting process, where the sub roller 220 is placed in contact with the main roller 210, the wheel w is in contact with the main roller 210 and the sub roller 210, as illustrated in FIG. 11. This is accomplished through a secondary position setting process that is sandwiched between rollers 220 and supported so that it can rotate in place.

Meanwhile, this second embodiment restricts further movement of the wheelchair (C) when the wheels (w) are located on the main roller 210 and the sub-roller 220 in the initial state, that is, when the first position setting is made. A setting stopper 250 may be further included.

In the initial state where the sub-roller 220 is close to the main roller 210, if the wheelchair (C) wheel (w) moves further after being positioned on the main roller 210 and the sub-roller 220, the sub-roller (220) ), so that the action of the wheel rotation unit 200 cannot be performed, so the setting stopper 250 prevents this departure by limiting further movement of the wheel (w) and allows the primary position setting to be performed efficiently. It is to be so.

As illustrated in the drawings, this setting stopper 250 is coupled to the connecting bar 242 of the displacement drive means 240 and extends upward in a streamlined form to position the primary position set wheel (w). It may be configured to limit backward movement and move backward in conjunction with the sub-roller 220 when it moves backward according to the operation of the displacement drive means 240.

That is, as illustrated in FIG. 9, when the wheel w is positioned on the main roller 210 and the sub roller 220 and is first set, the setting stopper 250 blocks the wheel by contacting the rear side of the wheel w. When the additional movement of (w) is restricted and the sub-roller 220 is then moved backward, it also moves backward.

At this time, when the setting stopper 250 moves backward together with the sub-roller 220, as illustrated in FIGS. 10 and 11, the wheel w is spaced apart from the sub-roller 220 and the main roller 210. As it moves downward through the space, a certain distance is created between the touching setting stopper 250 and the wheel w, so that the setting stopper 250 does not have any influence on the rotation of the wheel w.

Of course, as another example, the setting stopper 250 is connected to the displacement driving means 240 and additionally installs a separate hydraulic cylinder controlled by the roller displacement control unit, and the setting stopper 250 is coupled to this hydraulic cylinder to act as a sub-roller. Together with (220), it may be implemented to enable forward and backward movement.

According to the second embodiment configured as above, the wheelchair (C) is positioned in the wheel rotation unit 200 so that it can rotate in place, so that it can be safely positioned in the wheel rotation unit 200 without any impact, thereby ensuring safety. and convenience can be further improved.

In the above-described first embodiment, the sub-roller 220 is spaced rearward from the main roller 210 and is fixed, so the wheel w is connected to the main roller 210 and the sub-roller of the wheel rotation unit 200. When sandwiched between (220) and supported so as to rotate in place, there is a limit to the inevitable occurrence of shock.

That is, after the wheel (w) passes the main roller 210 on the front side, it goes through a process of being sandwiched between and supported by the sub roller 220. When the wheel (w) passes the main roller 210, the sub roller 210 Since it is spaced apart from the roller 220 at a certain distance, an impact is bound to occur between the wheel w and the sub-roller 220 when it is later supported on the sub-roller 220.

Therefore, in the process of setting the wheel (w) to the wheel rotation unit 200, such impact may cause discomfort and anxiety to the wheelchair (C) user, and also, if repeated use and impact occur for a long time, the sub roller (220) ) can also cause damage or breakage.

On the other hand, in this second embodiment, as can be seen through the continuous process illustrated in FIGS. 8 to 11, the sub roller 220 is initially close to the main roller 210 and comes into contact with the wheel w. It starts in the first setting process, and then moves backward while maintaining continuous contact with the wheel (w) to support the wheel (w) so that it can rotate in place, so the above shock does not occur at all, making it safer and more convenient. In this way, the wheelchair (C) can be positioned in the wheel rotation unit (200).

We have looked at preferred embodiments of the present invention above. According to this invention, by providing a simulation effect like actually driving in a wheelchair in various usage environments, not only the simple exercise ability of the wheelchair user, but also the driving ability and usage experience, etc. It can be seen that various abilities required by wheelchair users can be comprehensively improved.

In addition, it is not a process of simply rotating the wheel, but rather a simulation video controlled by the rotation of the wheel, allowing the user to experience various feelings and actively participate in the experience with greater fun and interest. It can provide motivation.

In addition, when the wheelchair is positioned for the simulation experience, it is seated smoothly without any impact, so it can be seen that the safety and convenience of use can be greatly improved.
