Description

BWS system using winch compensation traction device and its operating method {Body Weight Support System Having Winch Compensation Towing Device and Operating Method Thereof}

The present invention relates to a BWS system for gait training, and more particularly, to a BWS system capable of operating a BWS system in which a manual operation procedure is greatly reduced with diversification of training intensity with a winch compensation traction device.

In general, a walking towing system (BWS; Body Weight Support) (hereinafter referred to as the BWS system) is equipped with a weight compensation traction device so as not to feel a load burden by the weight of the walking trainer during walking training.

Specifically, the weight compensation traction device is divided into a weight application structure and an actuator application structure.

For example, the weight compensation traction device is a method of taking the load burden on the walking trainer as a weight, reducing the load burden and adjusting the intensity of walking training by increasing or decreasing the number of weights. On the other hand, the actuator compensation traction device takes charge of the load burden on the walking trainer as a combination of a spring and an actuator, and reduces the load burden and adjusts the walking training intensity through a change in the elastic reaction force of the spring in response to a change in the operation of the actuator.

Therefore, the BWS system can effectively obtain a bipedal walking posture experience that is helpful for gait training through brain plasticity by using a weight compensation traction device or an actuator compensation traction device.

On the other hand, the actuator compensation traction device has an advantage of excellent user convenience for the BWS system by almost eliminating the inconvenience of manual operation, but has a disadvantage in that the structure is complex and the manufacturing cost is high due to the combination of the spring and the actuator.

It is a flowchart of a method of operating a BWS system with reduced operation frequency, and FIG. 4 is an operating state of the winch compensation traction device according to the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying illustrative drawings, and such embodiments are described herein as examples because those of ordinary skill in the art may be implemented in various different forms. It is not limited to this embodiment.

Referring to FIG. 1, the BWS system 1 includes a remote control 1-7, a support frame 10-1, a winch compensation traction device 10-2, and a harness 50.

As an example, the remote control (1-7) drives and stops the winch (21) of the winch compensation traction device (10-2) forward/reverse rotation, and the winch (21) is wired to generate a winch drive/stop signal. Although the connected wired method is preferred, short-range wireless communication such as Bluetooth may be used.

For example, the support frame 10-1 is formed of a truss structure to form an internal empty space. For example, the support frame 10-1 is characterized by a frame body made of a horizontal frame bent at an upper end of a vertical frame that is placed on the floor and accommodates the winch compensation traction device 10-2 inside. In particular, the support frame (10-1) is located at a distance from each other inside the horizontal frame to maintain the tension of the winch wire (21-1) connected to the winch (21) of the winch compensation traction device (10-2). A wire roller 10A on which the winch wire 21-1 is hung is provided. In this case, the wire roller 10A applies a free rotation roller.

For example, the winch compensation traction device 10-2 is composed of a self-weight compensation winch 20, a winch motion guider 30, and a winch sensor 40.

Specifically, the self-weight compensation winch 20 includes a winch 21, a winch wire 21-1, a harness connecting end 21-1A, a winch balancer 23, and a winch balancer wire. It is composed of (23-1), weight (27), weight connection rod (29).

In particular, the winch compensation traction device 10-2 is about 0 for the additional weight of the harness received by the winch wire 21-1 from the Trainee 100 (eg, a walking trainer) wearing the harness 50. By implementing ~80kg as the compensation load range, and implementing about 60% of the compensation load range as a load compensation by the weight balance effect of the weight 27, the burden load received by the Trainee 100 is reduced to the maximum. It has the characteristic that it is possible to adjust the walking training intensity by increasing it to 60Kg.

In addition, the winch compensation traction device (10-2) is characterized by greatly improving user convenience by almost eliminating one manual operation of a training assistant (e.g., physical therapist) such as changing/fixing weight required for gait training intensity adjustment. Has.

Furthermore, the winch compensation traction device 10-2 can accumulate the variable weight weight for gait training intensity adjustment as personal data of the Trainee 100, so that big data and AI (Artificial AI) used for training performance analysis/improvement, etc. Intelligence) area.

For example, the winch 21 is stopped/driven and forward/reverse by the remote control 1-7, and the connected winch wire 21-1 is connected by forward rotation (or reverse rotation) or reverse rotation (or (Forward rotation). Therefore, the winch 21 is an electric winch using an electric motor as a driving source, and may include a motor driver (or inverter). In the winch wire 21-1, the opposite end of one end connected to the rotational shaft of the winch 21 is exposed to the support frame 10-1 and is connected to the harness connection end 21-1A. The harness connection end 21-1A connects the harness 50 worn by the trainee 100.

For example, the winch balancer 23 moves the winch 21 and the reverse direction (eg, applying the elevator weight principle) via the winch balancer wire 23-1 to the winch 21 and the winch motion guide 30. It acts as a winch weight that offsets the total weight (weight) of the winch structure. Therefore, the winch balancer 23 acts so that only the weight limited by the weight 27 minus the weight of the winch structure is applied to the trainee 100. In particular, the winch balancer 23 perforates a rod hole so that the sub post 37 penetrates. In addition, the winch balancer wire 23-1 is connected to the winch balancer 23 while one end is fixed to the winch plate 33 to allow the movement of the winch balancer 23, but LM ( Linear Motion) Guide rail or ball screw rod can be applied.

For example, the weight of the weight 27 is fixed to the winch plate 33 with a weight connecting rod 29 to follow the vertical movement of the winch 21, so that the weight of the weight of the weight 27 is applied to the track wearing the harness 50. It is provided by the load applied to the ini (100). Therefore, the weight of the weight 27 implements load compensation with a weight balance effect for the trainee 100 while the weight of the winch structure is removed.

In particular, the weight 27 is composed of a set of unit weights like the weight of a fitness exercise device by increasing or reducing the weight by combining unit weights, but by applying a laser reflector 47, a conventional weight fixing means There is a difference that does not apply.

Specifically, the winch motion guide 30 includes a main post 31, a winch plate 33, a sensor plate 35, a sub post 37, a post bracket 37-1, and a side plate 39. Consists of

For example, the main post 31 is vertically generated in the winch 21 due to a difference in the compensation load between the trayy 100 and the weight 27 when the winch wire 21-1 is wound (ie, wound or unwound). It guides the movement stably. In this case, the compensation load difference may adjust the unit weight quantity of the weight weight 27 so as to compensate the load of the trainee 100 in which walking training is performed in a weight range of about 0 to 80 Kg.

In particular, the length of the main post 31 is formed so that the trayy 100 is slightly separated from the floor at the lower end of the winch 21, and the number of the configurations is a winch plate 33 forming a square shape. It is composed of four main posts 31 each positioned as corners according to the shape of, but can be configured in various ways as 1-3.

For example, the winch plate 33 is provided as a place to mount the winch 21 and the associated winch accessory, and the main post 31 is fixed to each corner by having a rectangular plate shape. Therefore, the winch plate 33 is vertically moved together with the winch 21.

For example, the sensor plate 35 is fixed using a vertical frame of the support frame 10-1 so that the position is fixed against the vertical movement of the winch 21 and the plate 33. In particular, in the sensor plate 35, a post hole through which the main post 31 passes is drilled in each corner, and the winch upper position sensor 40-1 of the winch sensor 40 and the winch lower position sensor ( It is provided as a place where 40-2) is installed.

As an example, the sub-post 37 stably guides the winch balancer 23 in the upward movement of the winch 21 in the opposite direction to the movement direction of the winch 21. In particular, the sub-post 37 passes through the rod hole of the winch balancer 23 and moves up and down while one end is fixed to the post bracket 37-1 coupled to the side plate 39.

For example, the side plate 39 provides a place where the post bracket 37-1 for fixing the sub-post 37 for vertical movement of the winch balancer 23 is coupled, and the support frame 10-1 ) Is fixed using a vertical frame.

Specifically, the winch sensor 40 is divided into a winch upper position sensor 40-1, a winch lower position sensor 40-2, and a weight detection sensor 40-3.

For example, the upper position sensor 40-1 of the winch is located around a post hole drilled at one corner of the sensor plate 35, and acts as a stopper of the main post 31 for upward movement of the winch 21 do. The winch lower position sensor 40-2 is located around a post hole drilled at the other edge of the sensor plate 35, and acts as a stopper of the main post 31 for downward movement of the winch 21. .

To this end, each of the upper winch position sensor 40-1 and the lower winch position sensor 40-2 applies a non-contact structure.

For example, each of the upper winch position sensor 40-1 and the lower winch position sensor 40-2 is composed of a position sensor target 41 and a photo sensor 43. The position sensor target 41 forms a straight line in the form of a rod bar, and the photo sensor 43 emits light in a vertical movement path of the position sensor target 41. In addition, the position sensor target 41 is fixed to the winch plate 33 and moves together with the winch plate 33 while the photo sensor 43 is fixed to the sensor plate 35.

Therefore, the position sensor target 41 rises up and reaches the setting winch position (b) (eg, the upper winch position sensor 40-1) or goes down to reach the training winch position (c) (eg, the bottom of the winch Position sensor (40-2)), and the photo sensor 43 reaches the setting winch position (b) (e.g., the upper position of the winch (40-1)) or reaches the training winch position (c) ( Yes, the position sensor target 41 is in a state where the light is not blocked by the position sensor target 41 until the position sensor at the bottom of the winch (40-2), and the light is moved upward to reach the setting winch position (b). The system user (e.g., rehabilitation therapist) knows that the winch 21 has moved from the initial winch position (a) to the setting winch position (b) or from the setting winch position (b) to the training winch position (c). Is recognized. In this case, the position sensor target 41 may be set to operate in reverse, such as being configured to block light from the photo sensor 43 at the initial winch position (a).

However, each of the upper winch position sensor 40-1 and the lower winch position sensor 40-2 may employ a contact structure.

For example, each of the upper winch position sensor 40-1 and the lower winch position sensor 40-2 is composed of a position sensor target 41 and a photo sensor 43. The position sensor target 41 is formed in the form of a rod bar having a protruding protrusion at an end thereof, and is fixed to the winch plate 33 to move together with the winch plate 33. On the other hand, the photo sensor 43 is formed in the form of an open channel to accommodate the load bar, and is fixed to the sensor plate 35.

Therefore, the position sensor target 41 rises up to reach the setting winch position (b) or goes down to reach the training winch position (c), and the photo sensor 43 makes the protruding protrusion of the position sensor target 41 By restraining, the system user (e.g., rehabilitation therapist) can recognize that the winch 21 has moved from the initial winch position (a) to the setting winch position (b) or from the setting winch position (b) to the training winch position (c). have.

For example, the weight detection sensor 40-3 detects a change in distance according to an increase in the quantity of the weight 27. To this end, the weight detection sensor 40-3 includes an infrared sensor 45 and a reflector 47. The infrared sensor 45 generates infrared rays toward the floor, and the reflective plate 47 reflects infrared rays toward the infrared sensor 45. In addition, the reflector 47 fixes the unit weight combination of the weight 27 in place of the conventional weight fixing means.

In particular, the infrared sensor 45 is a laser sensor capable of measuring distance or a 3D type, and a LiDAR (Light Detection And Range) is applied that can measure the positional coordinates of the reflector by measuring the time to return after emitting light. can do.

Specifically, the harness 50 is connected to the harness connection end 21-1A of the winch wire 21-1 exposed from the support frame 10-1, and a wearing sheet that the Trainee 100 can wear. Equipped.

Meanwhile, FIG. 2 illustrates the effect of the winch sensor 40 applied to the winch compensation traction device 10-1.

First, referring to the upper winch position sensor 40-1 and the lower winch position sensor 40-2, the winch movement is limited to the initial winch position (a), the setting winch position (b), and the training winch position (c). .

For example, the initial winch position (a) refers to the initial state of the BWS system 1 in which the winch compensation traction device 10-1 including the winch 21 is not operated. Therefore, in the winch compensation traction device 10-1, the winch plate 33 and the sensor plate 35 are located close to each other, and the winch 21 is in a state lowered to the maximum together with the main post 31, whereas the winch balancer In contrast to the winch 21, 23 is in a state raised to the maximum by riding the sub post 37.

For example, the setting winch position (b) is implemented by forward rotation (or reverse rotation) of the winch 21. That is, when the winch 21 winds the loosened winch wire 21-1 tightly, the weight of the trayy 100, which is heavier than the total weight of the weight 27, is the winch wire 21 connected to the harness 50. -1). As a result, the winch wire 21-1 is lowered to lift the position 21 upward due to the weight of the trayy 100 due to the compensation load difference along with stopping the winding by the rotational force of the winch 21.

Therefore, the winch 21 is set at the initial winch position (a) by moving up with the winch plate 33 through the main post 31 while the sensor plate 35 is fixed by the weight of the tray 100. It is raised to the winch position (b). At the same time, the winch balancer 23 goes down and moves in the opposite direction to the winch 21 so that the weight of the winch structure does not get caught on the winch wire 21-1.

At this time, the position sensor target 41 of the winch upper position sensor 40-1 moves together with the winch plate 33 so that the photo sensor 43 is converted to a light-blocking state, so the winch 21 is at the initial winch position (a). It is recognized by the system user (eg, rehabilitation therapist) that it has moved to the setting winch position (b). On the other hand, the photo sensor 43 of the position sensor 40-2 below the winch is maintained in a state where light is not blocked by the position sensor target 41.

For example, the training winch position (c) is implemented as a reverse rotation (or forward rotation) of the winch 21. That is, the winch 21 lifts the trayy 100 upward from the floor with a strong rotational force, so that the winch wire 21-1 overcomes the weight of the trayy 100 and is wound around the winch rotation shaft.

Therefore, the winch 21 is lowered from the setting winch position (b) to the training winch position (c) by going down together with the winch plate 33 through the main post 31 while the sensor plate 35 is fixed. . At the same time, the winch balancer 23 rises upward and moves in the opposite direction to the winch 21 so that the weight of the winch structure is not caught on the winch wire 21-1.

At this time, the position sensor target 41 of the position sensor 40-2 at the bottom of the winch moves together with the winch plate 33 so that the photo sensor 43 is converted to a light blocking state, so the winch 21 is positioned at the setting winch position (b). It is recognized by the system user (eg, rehabilitation therapist) that it has moved from to the training winch position (c). On the other hand, the photo sensor 43 of the position sensor 40-1 at the top of the winch is maintained in a state where light is not blocked by the position sensor target 41.

Also, referring to the weight detection sensor 40-3, compensation weight data conversion is implemented by distance recognition.

As an example, the infrared sensor 45 of the weight detection sensor 40-3 uses the distance from the reflector 47 in which the fixed position of the weight 27 changes according to the applied quantity of the weight 27 as the weight detection distance. It measures and provides the weight detection distance to the data processor 49. Then, the data processor 49 converts the weight detection distance into a weight weight with a built-in distance-weight conversion table, and accumulates it as a weight weight data map as a compensation weight ratio for each trainee weight. To this end, the data processor 49 includes a central processing unit together with a memory.

Therefore, the winch compensation traction device (10-2) can extend the weight weight data map to the big data and AI areas, and the use of such big data and AI greatly enhances the walking training effect of the BWS system (1). You can contribute.

Meanwhile, FIG. 3 illustrates a method of operating a BWS system in which the BWS system 1 uses a winch compensation traction device 10-2.

As shown, the BWS system operating method is weighted on a winch 21 that winds or unwinds a winch wire 21-1 on which the additional weight of the harness hung on the harness 50 is pulled out of the support frame 10 A winch compensation traction device control that connects the weights 27 and realizes the weight balance effect of the weights 27 in which the weights added to the harness are compensated by the vertical movement of the winch 21. Include.

To this end, the BWS system operation method includes the BWS setting step of S10, the BWS wearing step of S20, the BWS warm-up step of S30, the BWS training step of S40, and the BWS training intensity adjustment step of S50. By reducing it to a small fraction, user convenience is provided very high by reducing the frequency of manual operation compared to the existing BWS method.

For example, the BWS setting (S10) requires a BWS manual operation procedure, which is illustrated as a setting for the winch compensation traction device 10-2 of S11. In this case, the manual operation of the BWS may include adjusting the weights 27 for the weight compensation ratio and walking training intensity.

Referring to Figure 4 (a), the initial winch position (a) of the winch compensation traction device 10-2 according to the BWS setting (S10) is illustrated. As shown, the initial winch position (a) in which the winch 21 of the winch compensation traction device 10-1 is not operated is formed close to each other with respect to the winch plate 33 and the sensor plate 35 The winch 21 is lowered to the maximum, while the winch balancer 23 is raised to the maximum. In addition, the amount of use of the weights 27 is determined according to the walking training intensity of the trainee 100, and the used weights are fixed using the reflector 47.

Therefore, the trainee instruction strength information according to the initial winch position (a) is the data processor 49 that calculates the compensation weight for each trainee weight by the weight detection distance of the infrared sensor 45 measuring the distance from the reflector 47. ), the training intensity information is saved in the weight data map.

As an example, the BWS wearing (S20) requires some of the BWS manual operation procedure, which is the winch forward rotation step in which the winch wire descends by the remote control operation of S21, the winch harness setting step for wearing the harness of the trainee in S22, S23 It is illustrated as a winch reverse rotation step in which the winch wire is raised by the remote control operation of the winch wire, and a winch reverse rotation increase step in which the trayny is raised from the floor by pulling the winch wire by the remote control operation of S24. In this case, since the BWS manual operation does not include the operation of the remote control 1-7, the BWS manual operation is limited to the harness setting for the harness 50 of the trainee 100.

As an example, the BWS warm-up (S30) does not require a BWS manual operation procedure, which is illustrated as a winch drive stop step by remote control operation of S31, and a winch forward rotation step by remote control operation to lower the trayy of S32 to the floor. . Therefore, manual operation of the BWS is not required.

Referring to Figure 4 (b), the setting winch position (b) of the winch compensation traction device 10-2 according to the wearing of the BWS (S20) is illustrated. As shown, the setting winch position (b) in which the winch 21 of the winch compensation traction device 10-1 is operated is a winch wire 21-1 in which the load of the tray 100 is connected to the harness 50 When the winch plate 33 and the sensor plate 35 are separated from each other, the winch 21 is raised to the maximum while the winch balancer 23 is lowered to the maximum.

Therefore, the photo sensor 43 of the upper winch position sensor 40-1 according to the setting winch position (b) is switched to the light blocking state by the position sensor target 41, while the lower winch position sensor 40-2 The photo sensor 43 of is maintained in a state where light is not blocked by the position sensor target 41.

For example, the BWS training (S40) does not require a BWS manual operation procedure, which is a winch drive stop step in which the treadmill walking speed operation is performed after the winch is stopped by the remote control operation of S41, the weight balance of the winch compensation traction device of S42 It is exemplified by the stage of effect generation. Therefore, manual operation of the BWS is not required.

As an example, since the BWS training intensity adjustment (S50) is a change in the BWS walking training cycle, the need for intensity adjustment means that a new training cycle is performed by resetting according to the return of the BWS setting in S10.

Referring to Figure 4 (c), the training winch position (c) of the winch compensation traction device 10-2 according to the wearing of the BWS (S20) is illustrated. As shown, the training winch position (c) stopped after the operation of the winch 21 of the winch compensation traction device 10-1 is a weight balance effect through compensation for the weight of the trainee of the weight 27. ), the walking motion of the trainee 100 is made while the feet are in contact with the floor.

At this time, the winch 21 moves up and down with the main post 31 responding to the walking motion of the trainee 100 using the training winch position (c) as the vertical movement area from the initial winch position (a), while the winch balance The standing 23 offsets the weight of the winch structure including the winch 21 that can be applied to the trainee 100 by moving in the opposite direction of the winch 21.

As described above, the BWS system 1 according to the present embodiment is provided on the support frame 10 in which the winch wire 21-1, which is connected to the harness 50 and receives the additional weight of the harness, comes out to the outside. The winch compensation traction device (10-2) compensates for the added weight of the harness by the weight balance effect of the weight (27) connected to the winch (21) where the winch wire (21-1) is wound and released. By doing so, the manufacturing cost of the BWS system 1 can be lowered compared to the actuator compensation traction device, and in particular, the combination of the weight detection sensor 40-3 together with the upper/lower winch position sensors 40-1 and 40-2 is used. It also provides user convenience for the BWS system (1) by minimizing manual operation.
