Description

Smart Robot Health Bike System

[0001] The present invention relates to a smart robot health bike system, and more specifically, to a smart robot health bike system configured so that the left and right crank shafts independently operate forward and backward when pedaling like pedaling a bicycle, thereby providing eight different types of rehabilitation exercises and enabling safe and efficient use.

[0002] In addition, the present invention relates to a system for providing customized rehabilitation exercise for the health-disadvantaged, and more specifically, to a system for providing customized rehabilitation exercise for the health-disadvantaged that can increase the effect of rehabilitation exercise by providing customized exercise content based on artificial intelligence and a rehabilitation bicycle for digital healthcare exercise service for the socially health-disadvantaged.

[0003] In addition, the present invention relates to a left-right variable rotation pedal-type exercise device for rehabilitation exercise, and more specifically, to a left-right variable rotation pedal-type exercise device for rehabilitation exercise in which, when pedaling like pedaling a bicycle, the rotation axis of the pedal operates forward / backward and the range of rotation of the pedal provides a separate rotation range for each left-right movement range of the body joints, thereby enabling rehabilitation exercise to be performed safely and efficiently.

[0004] One of the most important abilities for humans is the ability to walk and move. However, if a person with stiffness or discomfort in the body's muscles is not able to walk or exercise sufficiently for a long period of time, the joints may become hardened and the ability to move may be completely lost. In addition, the muscles throughout the body may contract and deteriorate. Therefore, to prevent this, continuous and repetitive joint movements must be performed.

[0005] Additionally, aerobic exercise, including walking, is suitable for health and rehabilitation for almost everyone, including the elderly with reduced mobility, diabetics, and those at risk for myocardial infarction, as well as those with paralysis or other physical disabilities. However, it may be difficult to perform aerobic exercise outdoors due to time, location, or physical limitations.

[0006] In cases of sarcopenia, a musculoskeletal disease, muscle thickness and density decrease and muscle strength decreases, making daily life (maintaining posture, exercising, etc.) difficult.

[0007] Additionally, patients with musculoskeletal disorders have stiff muscles and joints due to problems with the muscles and nervous system, resulting in unnatural movements and large differences in the range of motion and strength of the left, right, front, and back joints.

[0008] Meanwhile, when people with physical disabilities use a regular, conventional bicycle, they may experience problems with their sitting posture, and obese people and the elderly may experience problems with their back posture, which can lead to spinal diseases.

[0009] Additionally, people with back pain tend to bend their necks and backs more than the average person, which puts more strain on their spine and causes tension in their neck and back muscles, leading to more pain and discomfort.

[0010] Therefore, for the elderly who are severely obese and have weak lower limbs and a hunched back, using a regular standing / seated bicycle increases the burden on the cervical and lumbar (neck, lower back) discs.

[0011] Meanwhile, conventional rehabilitation bicycles for people with disabilities or those undergoing rehabilitation after injury take a long time to set up before they can start exercising, and it is difficult to maintain a body tilt when using them. In severe cases, this can lead to safety accidents in which the rehabilitation patient falls along with the bicycle when using them.

[0012] In other words, the reason why using a conventional bicycle is problematic for people with physical disabilities is that it lacks safety and convenience when used.

[0013] Specifically, there is a risk of falling when boarding and using the vehicle, and it is difficult for socially disabled people who use wheelchairs or walking aids to board without an assistant because they have difficulty standing on both feet.

[0014] Additionally, people with stiff joints who cannot straighten their knee joints have a problem with their body tilting due to a loss of left-right balance every time they turn the pedals because of a difference in the length of movement between their left and right legs.

[0015] This requires the protection of auxiliary personnel, raises safety issues and requires auxiliary personnel to be on standby at all times, is disadvantageous in terms of convenience, and is problematic in that it causes detailed discomfort.

[0016] The present invention was derived to solve the above-described problem, and the purpose of the present invention is to provide a rehabilitation bicycle for a digital healthcare exercise service for the socially disadvantaged and a customized rehabilitation exercise system for the socially disadvantaged that can increase the effect of rehabilitation exercise by providing customized exercise content based on artificial intelligence.

[0017] In addition, the present invention has another purpose of providing a customized rehabilitation exercise system for the health-impaired, which does not require separate equipment operation before boarding and allows continuous exercise without falling depending on the exercise posture performed while lying down, and which can provide rehabilitation for the health-impaired, who have difficulty exercising alone without an assistant due to decreased muscle function caused by aging and musculoskeletal and neurological diseases by applying different rotation radiuses on the left and right due to variable rotation pedals.

[0018] In addition, the present invention has another purpose of providing a customized rehabilitation exercise system for the health-impaired, which enables remote operation of a non-face-to-face rehabilitation bicycle and adjustment of exercise difficulty, and matches a professional rehabilitation exercise expert who analyzes exercise performance, thereby reducing costs through a non-face-to-face exercise service.

[0019] In addition, the present invention provides a left-right variable rotary pedal type exercise device for rehabilitation exercise, which enables rotation and forward-backward operation of the pedals when a rehabilitation patient pedals like pedaling a bicycle with his or her feet on both left and right pedals, thereby enabling rehabilitation exercise to be performed safely and efficiently. Another object of the present invention is to provide a left-right variable rotary pedal type exercise device for rehabilitation exercise, which enables rotation and forward-backward operation of the pedals when a rehabilitation patient pedals like pedaling a bicycle, and provides separate rotation ranges for the left and right upper and lower extremity joints, thereby enabling rehabilitation exercise to be performed safely and efficiently.

[0115] FIG. 4 is a block diagram illustrating a rehabilitation exercise provision server of a customized rehabilitation exercise provision system for the health-impaired according to the first embodiment of the present invention.

[0116] Referring to FIG. 4, the rehabilitation exercise provision server (500) may include a user management database (510), a trainer management database (520), a physical ability measurement unit (530), a trainer matching unit (540), an exercise care content training unit (550), and a remote exercise control unit (560).

[0117] The user management database (510) can manage user information about users associated with user terminals (100). User information can include user name, user gender, user date of birth, user contact information, user address, etc.

[0118] The user management database (510) can store test results for physical abilities measured by users through a rehabilitation exercise device (300) for each user. The user management database (510) can accumulate and store test results along with the test date for physical abilities.

[0119] Additionally, the user management database (510) can store, for each user, a first exercise care result value using the first exercise care content and a second exercise care result value using the second exercise care content.

[0120] The user management database (510) can store trainer information matched with a user in association with the user and store feedback related to rehabilitation exercise transmitted from the trainer terminal (200).

[0121] The trainer management database (520) can manage trainer information for trainers associated with trainer terminals (200). Trainer information can include trainer name, trainer gender, trainer date of birth, trainer contact information, trainer address, trainer qualification-related documents, etc.

[0122] The trainer management database (520) can store user information matched with a trainer in association with the trainer and store feedback related to rehabilitation exercise transmitted to the user terminal (100).

[0123] In one embodiment, the trainer management database (520) may store trainer grades based on the first and second exercise care results of a user matched with a trainer. For example, the trainer grade may be determined based on whether the user's physical ability has improved by comparing the initial user's test result with the first and second exercise care results. The trainer grade may be determined to be higher if the user's physical ability has improved by comparing the initial user's test result with the first and second exercise care results.

[0124] The physical ability measurement unit (530) can derive test results for a physical ability test measured using a rehabilitation exercise device (300). The physical ability measurement unit (530) is connected to the rehabilitation exercise device (300) and can derive test results of the user measured from a sensor device (not shown) installed in the rehabilitation exercise device (300).

[0125] In one embodiment, the physical ability measurement unit (530) can derive test results of a hand muscle strength test, a hand physical strength test, a foot muscle strength test, and a foot physical strength test measured using a rehabilitation exercise device (300).

[0126] Hand strength tests may include an arm forward push test including pushing both arms forward, pushing left arm forward, and pushing right arm forward; an arm backward pull test including pulling both arms back, pulling left arm back, and pulling right arm back; an arm clockwise rotation test including ipsilateral clockwise rotation of both arms, alternating clockwise rotation of both arms, clockwise rotation of the left arm, and clockwise rotation of the right arm; and an arm counterclockwise rotation test including ipsilateral counterclockwise rotation of both arms, counterclockwise alternating rotation of both arms, counterclockwise rotation of the left arm, and counterclockwise rotation of the right arm.

[0129] Foot fitness testing may include a foot target heart rate test and a foot target distance reach test during the foot strength test.

[0130] The physical ability measurement unit (530) can determine a physical ability grade based on the test results of a hand muscle strength test, a hand physical strength test, a foot muscle strength test, and a foot physical strength test. The physical ability measurement unit can determine a physical ability grade based on a physical ability score according to the following mathematical formula 1.

[0131] [Mathematical Formula 1]

[0132]

[0133] Pscore refers to the physical ability score, HPT refers to the hand strength test result, HPTs refers to the hand strength test reference value for the same age group, HST refers to the hand physical test result, HSTs refers to the hand physical test reference value for the same age group, FPT refers to the foot physical test result, FPTs refers to the foot physical test reference value for the same age group, FST refers to the foot physical test result, FSTs refers to the foot physical test reference value for the same age group, and α refers to the reward score, which is awarded when there is no help from a trainer. is calculated as , BPS means the user's basic physical fitness score, can mean the average basic physical fitness score for the same age group.

[0134] For example, if, without the assistance of a trainer, the hand strength test result is 40, the hand strength test reference point for the same age group is 65, the hand physical strength test result is 45, the hand physical strength test reference point for the same age group is 40, the foot physical strength test result is 50, the foot physical strength test reference point for the same age group is 55, the foot physical strength test result is 60, the foot physical strength test reference point for the same age group is 60, the user's base physical strength score is 48, and the average base physical strength score for the same age group is 50, then the physical ability score may be 4.04.

[0135] For another example, if a hand strength test result is 60 with the assistance of a trainer and the hand strength test reference for the same age group is 65, a hand strength test result is 50 and the hand strength test reference for the same age group is 40, a foot strength test result is 55 and the foot strength test reference for the same age group is 55, a foot strength test result is 65 and the foot strength test reference for the same age group is 60, then the physical ability score could be 4.25.

[0136] Here, the physical ability score can be between 0 and 10, and if 0≤Pscore≤0.99, the physical ability grade is 10, if 1≤Pscore≤1.99, the physical ability grade is 9, if 2≤Pscore≤2.99, the physical ability grade is 8, if 3≤Pscore≤3.99, the physical ability grade is 7, if 4≤Pscore≤4.99, the physical ability grade is 6, if 5≤Pscore≤5.99, the physical ability grade is 5, if 6≤Pscore≤6.99, the physical ability grade is 4, if 7≤Pscore≤7.99, the physical ability grade is 3, if 8≤Pscore≤8.99, the physical ability grade is 2, and if 9≤Pscore≤10, the physical ability grade can be 1.

[0137] Referring to FIG. 7, the physical ability measurement unit (530) can output the test process and test results of a hand muscle strength test, a hand physical strength test, a foot muscle strength test, and a foot physical strength test to a content output device (400). The content output device (400) can output screens related to the test process and test results, such as a screen for instructing a test, a screen for showing a test result, and a screen for showing a test analysis result.

[0138] Referring back to FIG. 2, the trainer matching unit (540) can match users with trainers based on physical ability ratings and trainer information. For example, the trainer matching unit (540) can match users with high physical ability ratings with experienced trainers, or users with high physical ability ratings with less experienced trainers.

[0139] In one embodiment, the trainer matching unit (540) can match a user selected trainer on a user terminal (100) or a trainer selected user on a trainer terminal (200).

[0140] The trainer matching unit (540) can limit the number of users matched per trainer based on the user's physical ability level. For example, the trainer matching unit (540) can adjust the number of users matched per trainer to be lower as the user's physical ability level decreases, and to be higher as the user's physical ability level increases. This is to allow trainers to intensively monitor and provide feedback to users with low physical ability levels, and by intensively managing users with low physical ability levels, it can help improve the physical ability levels of the users.

[0141] The exercise care content training unit (550) can generate first exercise care content to compensate for the left and right joint ability deviations of the hand and the left and right joint ability deviations of the foot based on the test results and output the first exercise care content to the content output device (400). Here, the left and right joint ability deviations of the hand and the left and right joint ability deviations of the foot can occur because the physical abilities of the left and right arms, left and right feet are different for each user, and the exercise care content training unit (550) can minimize the left and right joint ability deviations of the hand and the left and right joint ability deviations of the foot by performing a test that intensively rehabilitates and strengthens the areas where joint ability is reduced.

[0142] The exercise care content training unit (550) can create first exercise care content that adjusts customized rehabilitation exercise and exercise difficulty according to the user's left and right hand joint ability deviation and the left and right foot joint ability deviation.

[0143] The exercise care content training unit (550) can generate first exercise care content in timer mode and first exercise care content in tabata mode as first exercise care content. The first exercise care content in timer mode is content that allows for performing a preset target exercise intensity for a preset exercise time, thereby improving joint and muscle strength. The first exercise care content in tabata mode is content that allows for performing a preset target exercise intensity and rest alternately, thereby promoting dieting and strengthening physical strength.

[0144] FIG. 8 is a drawing illustrating a timer mode first exercise care content screen provided by a system for providing customized rehabilitation exercise for the health-impaired according to the first embodiment of the present invention. Referring to FIG. 8, the timer mode first exercise care content can display a target exercise intensity and a target exercise time and provide data measuring the body length and physical ability of each of the left and right sides.

[0145] FIG. 9 is a drawing exemplifying a Tabata mode first exercise care content screen provided by a system for providing customized rehabilitation exercise for the health-impaired according to the first embodiment of the present invention. Referring to FIG. 9, the Tabata mode first exercise care content may display a target exercise intensity and a number of rest times, display a time for performing the target exercise intensity and a time for resting, and provide data measuring the body length and physical ability of each of the left and right sides.

[0146] Referring again to FIG. 2, the exercise care content training unit (550) can calculate the rehabilitation performance score according to the user's performance of the first exercise care content according to the following mathematical formula 2.

[0147] [Equation 2]

[0148]

[0149] Rscore refers to a rehabilitation performance score, G1 refers to a numerical value of the target exercise intensity in the timer mode first exercise care content, T1 refers to a converted value of the target exercise time in the timer mode first exercise care content, S1 refers to a target rehabilitation reference value in the timer mode first exercise care content, w1 refers to a weight according to age in performing the timer mode first exercise care content, G2 refers to a numerical value of the target exercise intensity in the Tabata mode first exercise care content, C1 refers to the number of times the target exercise intensity was performed in the Tabata mode first exercise care content, S2 refers to a target rehabilitation reference value in the Tabata mode first exercise care content, w2 refers to a weight according to age in performing the Tabata mode first exercise care content, C2 refers to the number of times rest was performed in the Tabata mode first exercise care content, and S3 may refer to a numerical value of the target number of times in the Tabata mode first exercise care content.

[0150] For example, when the target exercise intensity is quantified as 10 in the timer mode first exercise care content, the target exercise time is converted as 180 in the timer mode first exercise care content, the target rehabilitation reference value is 2000 in the timer mode first exercise care content, the weight according to age for performing the timer mode first exercise care content is 0.3, the target exercise intensity is quantified as 8 in the Tabata mode first exercise care content, the number of times the target exercise intensity is performed as 5 in the Tabata mode first exercise care content, the target exercise intensity is quantified as 50 in the Tabata mode first exercise care content, the weight according to age for performing the Tabata mode first exercise care content is 0.4, the number of times rest is performed as 5 in the Tabata mode first exercise care content, and the target number of times is quantified as 6 in the Tabata mode first exercise care content, the rehabilitation performance score may be 38.9.

[0151] The rehabilitation exercise provision server (500) can provide exercise points based on the rehabilitation performance score. Exercise points can be used like cash, for example, to purchase items via mobile devices or for trainer fees. In the example above, if the rehabilitation performance score is 38.9, the exercise points can be 38.

[0152] The exercise care content training unit (550) can generate exercise guide pop-ups that provide exercise guides based on test results, and second exercise care content based on exercise backgrounds and exercise avatars selected by the user, and output them to the content output device (400). The second exercise care content is exercise content that adds game elements to increase interest and motivation in exercise, and can allow people with poor health to indirectly experience travel that they would not normally be able to experience due to physical discomfort.

[0153] FIG. 10 is a drawing exemplifying a second exercise care content screen provided by a customized rehabilitation exercise provision system for the health-impaired according to the first embodiment of the present invention. Referring to FIG. 10, the exercise care content training unit (550) allows a user to select a desired training course, select a season (spring, summer, fall, winter) and a location (mountain, sea, school, countryside, space, overseas, etc.) as an exercise background, and select a person (man, woman, child, celebrity, etc.), an animal, a specific cartoon character, etc. as an exercise avatar, thereby generating second exercise care content including the selected training course, exercise background, and exercise avatar. The exercise care content training unit (550) can provide an exercise guide pop-up (1.5km left!! Let's push a little harder!!, Let's slowly rotate your left foot 10 times to increase speed!, etc.) to lead and assist the user's exercise in the second exercise care content.

[0154] The exercise care content training department (550) allows users to travel in a virtual exercise environment and enjoy the game, thereby maximizing the effect of exercise and promoting psychological care.

[0155] The remote exercise control unit (560) can remotely control the control of the rehabilitation exercise device, exercise intensity control through the first exercise care content and the second exercise care content, and real-time user consultation.

[0156] The remote exercise control unit (560) can control the rehabilitation exercise device (300) by a trainer who owns a trainer terminal (200) or an administrator who manages a rehabilitation exercise provision server (500). The rehabilitation exercise device (300) can be controlled by remote control to adjust the position and angle of the rehabilitation chair or the position and height of the rehabilitation pedal.

[0157] The remote exercise control unit (560) can monitor the user's heart rate, the user's exercise status, etc., to adjust the exercise intensity when the user performs exercise through the first exercise care content and the second exercise care content.

[0158] The remote exercise control unit (560) can perform real-time user consultations via a user terminal (100) or content provision device (400) to manage and provide feedback on the user's condition online. User consultations can be conducted by a trainer or rehabilitation doctor, etc.

[0159] The rehabilitation exercise provision server (500) according to the present embodiment can prevent sarcopenia, musculoskeletal diseases, and metabolic syndrome by improving muscle strength and fixing functions through self-exercise of the physically challenged, and can minimize the cost burden of non-face-to-face exercise services by remotely replacing assistant personnel required for safety assistance during exercise of the physically challenged.

[0163] The artificial intelligence analysis unit (570a) can collect exercise results using the rehabilitation exercise device (300) and preprocess them into an analyzable form. The artificial intelligence analysis unit (570a) can collect test results by age group of the user and preprocess the test results, and can collect the first exercise care result value for the first exercise care content and the second exercise care result value for the second exercise care content and preprocess the first exercise care result value and the second exercise care result value.

[0164] The artificial intelligence analysis unit (570a) can preprocess the collected result data by processing missing values ​​and outliers of the test result values, the first exercise care result values, and the second exercise care result values, and applying scaling and normalization.

[0165] The artificial intelligence analysis unit (570a) can analyze the correlation between the rehabilitation exercise prescription (target exercise intensity provided in the first exercise care content, exercise guide provided in the second exercise care content) and the rehabilitation exercise outcome value based on the preprocessed result data. Here, the correlation can be achieved by applying statistical methods and machine learning algorithms.

[0166] The artificial intelligence analysis unit (570a) can train an artificial intelligence model based on the results of the analysis of the output data. The training of the artificial intelligence model can be accomplished by determining the model structure, hyperparameters, loss function, etc.

[0167] That is, the artificial intelligence analysis unit (570a) can supplement customized exercise content by learning the preprocessed test result value, the preprocessed first exercise care result value, and the preprocessed second exercise care result value based on artificial intelligence.

[0168] The rehabilitation exercise provision server (500a) according to this embodiment can measure the exercise ability of people with poor health by utilizing a rehabilitation exercise device (300) and build big data to computerize the rehabilitation and senior-friendly exercise industry.

The pedal (666) is configured to be operated forward and backward in a sliding manner along the length direction of the base (610).

[0194] Meanwhile, in the second embodiment of the present invention, the seat (630) and the backrest (650) are configured to be tilted backward by a rotational operating support from the base (610).

[0195] In addition, in the second embodiment of the present invention, the lower portions of the left and right pairs of rear rotation operating frames (644) are coupled to the left and right pairs of lower base bars (612) of the base (610) via hinges, a rear seat support frame (642) is coupled to the bottom surface of the seat (630), and the front end of the rear seat support frame (642) is coupled to the upper portion of the rear rotation operating frame (644) via hinges.

[0196] In the second embodiment of the present invention, the rear frame (640) includes a rear seat support frame (642) that supports the seat (630) from below, a rear rotation operating frame (644) whose upper end is connected to the rear seat support frame (642) via a hinge and whose lower end is connected to a pair of lower base bars (612) on the left and right sides of the base (610) via a hinge, and a rear backrest (650) support frame whose lower end is connected to a pair of lower base bars (610) on the left and right sides of the base (610) via a hinge and whose middle part between the upper end and the lower end is connected to the rear end of the rear seat support frame (642) via an intermediate hinge, and on which the backrest (650) is supported at the front.

[0197] The above rear backrest frame (646) is formed in a square frame shape, and the lower part of the above rear backrest frame (646) is connected to a pair of lower base bars (612) of the above base (610) via a hinge.

[0198] At this time, the rotational operating support may be configured with a rotational operating cylinder (670) in which a cylinder rod is connected to a rear frame (640) that supports the seat (630) and the backrest (650) via a front hinge, and a base end is connected to the base (610) via a base (610) hinge.

[0199] The above seat (630) and the backrest (650) are configured to be tilted backward by a pivoting support from the base (610), and the pivoting support is configured with the pivoting cylinder (670), and the cylinder rod of the pivoting cylinder (670) is connected to the rear pivoting frame (644) for supporting the seat (630) and the backrest (650) via a front hinge, so that the pivoting cylinder (670) is connected to the rear frame (640) for supporting the seat (630) and the backrest (650) via the front hinge, and the base end of the pivoting cylinder (670) is connected to the base (610) via a base (610) hinge (i.e., connected to a lower base bar (612) constituting the base (610).

[0200] In other words, the cylinder rod of the pivoting cylinder (670) is connected to the seat (630) support side bracket extending downward toward the front end of the rear seat support frame (642) via a front hinge, and the base end of the pivoting cylinder (670) is connected to a pair of lower base bars (612) constituting the base (610) via a hinge, so that the cylinder rod of the pivoting cylinder (670) is connected to the rear frame (640) supporting the seat (630) and the backrest (650) via a front hinge, and the base end is connected to the base (610) via a base (610) hinge.

[0201] The rear backrest frame (646) is provided with a backrest (650) to support the back of a rehabilitation patient from behind, and side guides (656) are further provided on the rear backrest frame (646) to be positioned on both left and right sides of the backrest (650). The rear backrest frame (646) is provided with a pair of left and right side guides (656). The pair of left and right side guides (656) support the upper body of the rehabilitation patient more stably from both left and right sides, thereby helping to enable the rehabilitation patient to perform lower body rehabilitation exercise or arm rehabilitation exercise more stably.

[0202] When the cylinder rod of the above-described rotational operation cylinder (670) is moved forward, the rear rotational operation frame (644) is rotated to a position that is relatively higher up in the forward direction, the rear seat support frame (642) is also rotated to a position that is relatively higher up, the seat (630) is raised to be arranged in a horizontal direction, and the backrest (650) is in an upright state.

[0203] In this state, the rehabilitation patient places his / her buttocks on the seat (630) and the backrest (650) supports the patient's back from behind, that is, while the rehabilitation patient is sitting, he / she holds a pair of pedals (666) on the left and right with both hands and turns the pair of pedals (666) on the left and right like turning bicycle pedals (666), thereby allowing the rehabilitation patient to perform arm exercises.

[0204] Meanwhile, in a state where the cylinder rod of the above-mentioned rotational operation cylinder (670) is moved backward, the rear rotational operation frame (644) is tilted so as to be relatively laid back, the rear seat support frame (642) is also tilted so as to be relatively laid back, the seat (630) is tilted so as to be inclined backward, and the rear backrest frame (646), the backrest (650), and the left and right side guides (656) are also tilted back so as to be tilted back at a certain angle, and the rehabilitation patient places his or her buttocks on the seat (630), so that the seat (630) supports the buttocks of the rehabilitation patient from below, and at the same time, the backrest (650) supports the back of the rehabilitation patient from below, in other words, in a state where the patient lies down and places both left and right feet on the pedals (666), the rehabilitation patient turns a pair of left and right pedals (666) with both legs and feet like turning bicycle pedals (666), thereby allowing the rehabilitation patient to exercise the lower body, especially the leg, It becomes possible to implement.

[0205] As described above, the second embodiment of the present invention can be configured such that when a rehabilitation patient performs an exercise of rotating a pair of pedals (666) and the pedaling connecting links (666RL) with both feet, the crank body (664) rotates and at the same time, a pair of pedals (666) coupled to the crank support box (662), the crank body (664), and the pair of pedaling connecting links (666RL) slide forward and backward along the moving slot of the base-side pedaling frame (618). That is, the lower part of the crank support box (662) is slidably supported on the base-side pedaling frame (618) of the base (610), and the crank support box (662), the crank body (664), and the pair of pedals (666) are slidably coupled to the base-side pedaling frame (618).

[0206] Accordingly, according to the second embodiment of the present invention, when a rehabilitation patient performs an exercise of rotating a pair of pedals (666) and the pedaling connecting link (666RL) by placing both feet on a pair of left and right pedals (666) as if stepping on a bicycle pedal (666), the crank body (664) rotates and at the same time, a pair of pedals (666) connected to the crank support box (662), the crank body (664), and the pair of pedaling connecting links (666RL) slide forward and backward along the moving slot of the base-side pedaling frame (618), which is the main part of the base (610), thereby enabling the rehabilitation patient to perform leg rehabilitation exercise or waist rehabilitation exercise, which is a lower body part, by the forward and backward movement while turning the pair of pedals (666).

[0207] At this time, as described above, the rehabilitation patient is sitting on the seat (630), the backrest (650) supported on the base (610) is raised so that the back of the rehabilitation patient is supported from behind by the backrest (650), and a rehabilitation exercise of the arm portion can be performed in which the rehabilitation patient holds a pair of pedals (666) with both hands and turns a pair of pedals (666) like turning a bicycle pedal (666), or the rehabilitation patient is resting his / her buttocks on the seat (630), and the backrest (650) supported on the base (610) is laid back by the rotational operating support so that the back of the rehabilitation patient is supported from below by the backrest (650), in other words, the rehabilitation patient is lying down, and a rehabilitation exercise of the rehabilitation patient attaching his / her feet to a pair of pedals (666) and turning a pair of pedals (666) like turning a bicycle pedal (666) can be performed.

[0208] Therefore, in the case of the left-right variable rotation pedal-type exercise machine for rehabilitation exercise of the second embodiment of the present invention, when a rehabilitation patient places his or her feet on both pedals (666) and pedals as if stepping on the pedals (666) of a bicycle, both pedals (666) rotate and move forward and backward based on the crank support box (662), so that even a rehabilitation patient with a physical disease such as a hip joint can perform rehabilitation exercise in a balanced manner. Meanwhile, as described above, in the case of the left-right variable rotation pedal-type exercise machine for rehabilitation exercise of the second embodiment of the present invention, when a rehabilitation patient sits, holds a pair of pedals (666) with both hands and turns them as if turning a bicycle pedal, both pedals (666) rotate and move forward and backward based on the crank support box (662), so that a rehabilitation patient can also safely and efficiently perform rehabilitation exercise of the arm part. In the second embodiment of the present invention, the pedal (666) can be rotated relative to the base (610), which is a stable structure at the bottom, and can be operated forward and backward at the same time. Therefore, even a rehabilitation patient with a physical disease such as a hip joint can perform rehabilitation exercise for the lower body, especially the legs, in a balanced manner, and, if necessary, can perform rehabilitation exercise for the arms in a sitting position, which is more significant.

[0209] In other words, the left-right variable rotation pedal-type exercise device for rehabilitation exercise of the second embodiment of the present invention has the effect of enabling balanced rehabilitation exercise even for patients with physical diseases such as hip joint disease, because when a rehabilitation patient pedals like pedaling a bicycle (666) by placing their feet on both left and right pedals (666), both pedals (666) move forward and backward based on the crank support box (662).

[0210] For example, when a rehabilitation patient with a hip joint in one leg performs a pedaling exercise by placing both feet on the left and right pedals (666) and stepping on both pedals (666), if both pedals (666) do not move forward or backward but remain stationary, it is difficult to perform a rehabilitation exercise on the leg with the hip joint. However, in the second embodiment of the present invention, when a pedaling exercise is performed by stepping on both left and right pedals (666), both left and right pedals (666) rotate like bicycle pedals (666) and simultaneously move forward and backward in the crank support box (662), so that even a rehabilitation patient with a physical disease such as a hip joint can perform a rehabilitation exercise in a balanced manner.

[0211] In addition, since the second embodiment of the present invention allows a rehabilitation patient to perform rehabilitation exercises while sitting or lying down stably, it also has the effect of preventing serious safety accidents, such as a rehabilitation patient falling and sustaining an injury while performing rehabilitation exercises.

[0212] In the second embodiment of the present invention, a rehabilitation exercise of the lower body is possible like a lying-down bicycle that performs a pedaling function by turning a pair of pedals (666) while a rehabilitation patient lies down. While a conventional standing bicycle does not have a backrest (650), a backrest (650) is provided. Comparing the waist pressure, when performing rehabilitation exercise while lying down like in the second embodiment of the present invention, the pressure is 0.75 bar when the lying angle is 45 degrees, whereas the pressure of the conventional standing bicycle is 1.5 bar and the pressure of the conventional sitting bicycle is 1 bar. Therefore, it can be seen that when performing rehabilitation exercise while lying down like in the second embodiment of the present invention, the waist pressure is reduced, so that rehabilitation exercise of the legs and waist can be performed without strain.

[0213] Additionally, the second embodiment of the present invention features a neck support function in the supine position. In the supine position, the upper front portion of the backrest (650) functions as a neck support, supporting the head and neck of the rehabilitation patient from behind. Conventional standing and recumbent bicycles do not have a neck support function.

[0214] According to the second embodiment of the present invention, when performing rehabilitation exercise in a lying position, the weight of the neck is significantly reduced compared to that of a conventional upright bicycle and a recumbent bicycle. When the weight of the neck is 5 kg, when performing rehabilitation exercise in a lying position according to the second embodiment of the present invention, the weight of the neck is approximately 2 to 3 kg, whereas the weight of the neck of a conventional upright bicycle is approximately 12.2 kg and the weight of the neck of a conventional recumbent bicycle is 8 to 10 kg. Therefore, when performing rehabilitation exercise in a lying position according to the second embodiment of the present invention, the weight of the neck is significantly reduced, thereby preventing a rehabilitation patient from having the effect of the rehabilitation exercise reduced due to excessive load applied to the neck during the rehabilitation exercise.

[0215] Meanwhile, as described above, a pair of upright posts (615EP) are provided on the inside of the upright base frame (615), and the front connection reinforcing bar (616) is slidably connected to the pair of upright posts (615EP) on the left and right so as to be able to slide up and down, and the upper surface of the front connection reinforcing bar (616) and the upper surface of the front cross bar (613) are configured such that the upper and lower ends of a pair of left and right base-side springs (615SP) connected to the outer peripheral surfaces of the pair of upright posts (615EP) on the left and right are in contact with each other, and the base (610) may further include an elevation operation unit connected between the lower surface of the base-side pedaling frame (618) and the lower base bar (612), and the elevation operation unit may be configured as an elevation operation cylinder (622) having a vertical cylinder rod connected to the lower surface of the base-side pedaling frame (618) and a lower end connected to the lower base bar (612).

[0216] When the cylinder rod of the elevating operation cylinder (622) is raised, the front connection reinforcement bar (616), the front cross bar (613), and the base side pedaling frame (618) are raised, so that the height of the crank support box (662) and the pair of left and right pedals (666) can be relatively increased, and the pair of left and right base side springs (615SP) are stretched so that the front cross bar (613), the base side pedaling frame (618), the crank support box (662), and the pair of left and right pedals (666) can be stably supported by elastic force, and when the cylinder rod of the elevating operation cylinder (622) is lowered, the front connection reinforcement bar (616), the front cross bar (613), and the base side pedaling frame (618) are lowered, so that the height of the crank support box (662) and the pair of left and right pedals (666) can be relatively decreased, and the pair of left and right springs (615SP) are The base side spring (615SP) is compressed to stably support the front cross bar (613), the base side pedaling frame (618), the crank support box (662), and a pair of left and right pedals (666).

[0217] Accordingly, the second embodiment of the present invention can freely adjust the height of a pair of pedals (666) in response to the physical condition of the rehabilitation patient, such as the height of the rehabilitation patient, and thus can be expected to have a more helpful effect in the rehabilitation exercise of the rehabilitation patient.

[0218] Meanwhile, in the second embodiment of the present invention, the base-side pedaling frame (618) of the base (610) is configured in a box shape with a hollow portion therein, a spring coupling shaft (618SCS) is built into the interior of the Bates-side pedaling frame, a first guide spring (618FGS) and a second guide spring (618SGS) are coupled to the outer circumference of the spring coupling shaft (618SCS), and the crank support box (662) is coupled to the lower portion thereof via a connecting bracket (618CB) so as to be able to move forward and backward along the spring coupling shaft (618SCS). The inner ends of the first guide spring (618FGS) and the second guide spring (618SGS) are in contact with both ends of the connecting bracket (618CB).

[0219] Accordingly, in the second embodiment of the present invention, when a rehabilitation patient places his / her feet on both left and right pedals (666) and pedals as if stepping on the bicycle pedals (666), the crank support box (662), the connection bracket (618CB), and both pedals (666) are operated forward and backward together in the base-side pedaling frame (618), and when the crank support box (662), the connection bracket (618CB), and both pedals (666) move forward in the base-side pedaling frame (618), the first guide spring (618FGS) is extended and the second guide spring (618SGS) is compressed, and when the crank support box (662), the connection bracket (618CB), and both pedals (666) move backward in the base-side pedaling frame (618), the first guide spring (618FGS) is compressed and the second guide spring (618SGS) is extended, thereby providing an appropriate intensity of rehabilitation exercise for the lower body part of the rehabilitation patient. Because it can be maintained with elasticity, it has the effect of enabling rehabilitation exercise of appropriate intensity for the lower body of rehabilitation patients.

[0220] In addition, when a rehabilitation patient sits, holds a pair of pedals (666) with both hands and turns them as if turning bicycle pedals (666), the crank support box (662), the connecting bracket (618CB), and both pedals (666) move forward and backward in the base-side pedaling frame (618), and when the crank support box (662), the connecting bracket (618CB), and both pedals (666) move forward in the base-side pedaling frame (618), the first guide spring (618FGS) is extended and the second guide spring (618SGS) is compressed, and when the crank support box (662), the connecting bracket (618CB), and both pedals (666) move backward in the base-side pedaling frame (618), the first guide spring (618FGS) is compressed and the second guide spring (618SGS) is extended, so that the intensity of rehabilitation exercise for the upper body part of the rehabilitation patient, especially the arm part, is also appropriate. Since it can be maintained with elasticity, it also has the effect of enabling rehabilitation patients to perform rehabilitation exercises of appropriate intensity on their upper body.

[0221] When the base-side pedaling frame (618) of the above base (610) moves forward and backward, the compression and extension functions of the first guide spring (618FGS) and the second guide spring (618SGS) enable rehabilitation exercise with appropriate elastic strength for the lower body or upper body of the rehabilitation patient, so it is significant in that it is more helpful for the rehabilitation exercise of the rehabilitation patient.

[0222] The second embodiment of the present invention incorporates the pedaling and leg press push functions of a recumbent bicycle, inspired by the recumbent cycle and power leg press, thereby enabling comprehensive rehabilitation. In other words, the second embodiment of the present invention can be considered a comprehensive rehabilitation cycle.

[0223] It should be easy for a person with physical disabilities to sit on exercise equipment, and the chair should not be too high. The second embodiment of the present invention was developed to enable rehabilitation exercise by sitting stably on a seat (630) (chair) of an appropriate height that is easy to sit on, taking these factors into consideration.

[0224] In the second embodiment of the present invention, when a rehabilitation patient sits on a seat (630), the patient's weight is supported by the backrest (650) and the seat (630), ensuring safety. The backrest (650) and the seat (630) faithfully perform their roles of supporting the neck, waist, and hips, ensuring that the rehabilitation patient sits in an upright posture.

[0225] The second embodiment of the present invention enables precise joint target movement, etc. by performing exercise without the left and right reaction of the body of the rehabilitation patient and without putting weight on the body when pedaling by turning the pedal (666) after sitting on the seat (630).

[0226] The second embodiment of the present invention has a variety of exercise methods and exercise intensity application functions. When pedaling by turning a pair of pedals (666), an automatic length adjustment function is provided so that exercise is possible even if the length of the joints of the left and right upper and lower limbs are different, so that appropriate rehabilitation exercise corresponding to the length and muscle strength of the left and right joints is possible. In particular, the second embodiment of the present invention is more meaningful in that it is implemented so that appropriate rehabilitation exercise corresponding to the physical conditions of the left and right joints, muscle strength, hip joint of one leg, etc. of a rehabilitation patient is possible through an operating mechanism in which the pedals (666) rotate forward and backward while rotating as described above, rather than a backrest (650). The difficulty level is subdivided so that it can be applied to people with lack of muscle strength, so that both hands and feet can perform pedaling exercise together (i.e., pedaling exercise can be performed together for the arms and legs).

[0227] Meanwhile, the second embodiment of the present invention is configured such that a monitor-side connection support frame (682) is provided on the rear backrest frame (646), and a monitor (684) (LED monitor (684)) is mounted on the monitor-side connection support frame (682), so that the rehabilitation patient can operate the monitor (684) screen by touching (LED screen touching) or using a controller while sitting or lying on the seat (630), thereby enabling the rehabilitation patient to play games or watch TV on the screen of the monitor (684) while performing rehabilitation exercises.

[0228] In these cases, rehabilitation patients can play games or watch TV while doing rehabilitation exercises to prevent them from getting bored.

[0229] At this time, the monitor (684) is configured to be angle-adjustable by an angle-adjusting means in the monitor (684) side connection frame, so that the game posture angle can be adjusted, and the game posture angle adjustment makes it easy to adjust the center of resistance position between the pedal (666) and the rehabilitation exercise part of the rehabilitation patient when pedaling the pedal (666), so that the rehabilitation exercise can be performed without hindrance while enjoying the game.

[0230] Meanwhile, as described above, the rear seat support frame (642) is coupled to the lower surface of the seat (630), and the front end of the rear seat support frame (642) is coupled to the upper end of the rear rotation operation frame (644) via a hinge, and the lower end of the rear seat support frame (642) is connected to a pair of lower base bars (612) on the left and right sides of the base (610) via a hinge, so that when the rear backrest frame (646) is raised forward from the base (610) based on the lower hinge connected to the base (610) (i.e., the lower hinge connected to the lower base bar (612) of the base (610) to which the pair of backrest frame bars (646FB) on the left and right sides are connected), the rear rotation operation frame (644) is relatively rotated by the hinge connected to the rear seat support frame (642) and the hinge connected to the lower base bar (612). By being raised further upward, the seat (630) is supported more stably in a horizontal state in which it is raised, and when the rear backrest frame (646) is laid back from the base (610) based on the lower hinge connected to the base (610) (i.e., the lower hinge to which a pair of backrest frame bars (646FB) on the left and right are connected to the lower base bar (612) of the base (610), the rear rotation operation frame (644) is rotated to be laid down relatively more downward by the hinge connected to the rear seat support frame (642) and the hinge connected to the lower base bar (612), so that the seat (630) is relatively lowered further and supported more stably in a folded state.

[0231] Accordingly, when performing rehabilitation exercise by placing the buttocks on the sheet (630), the buttocks of the rehabilitation patient are supported more stably and firmly by the sheet (630), thereby providing greater assistance in the rehabilitation exercise of the rehabilitation patient.

[0232] Meanwhile, FIG. 26 is a side view schematically showing the structure of a left-right variable rotation pedal type exercise device for rehabilitation exercise according to a modified example of the second embodiment of the present invention, and FIG. 27 is a plan view schematically showing the structure of a left-right variable rotation pedal type exercise device for rehabilitation exercise according to another modified example of the second embodiment of the present invention.

[0233] A second embodiment of the present invention further includes a rear buffer structure (690) provided on the base (610) to absorb shock when the rear backrest frame (646) is tilted backward from the base (610).

[0234] The rear shock absorbing structure (690) is characterized by including a shock-up sleeve (692) having a lower end fixed to the upper surface of the rear cross bar (614) of the base (610) and arranged in an up-and-down direction; a shock-up bar (694) slidably coupled to the inside of the shock-up sleeve (692) and having a portion exposed to the upper end of the shock-up sleeve (692); and a shock-up spring (696) built into the inside of the shock-up sleeve (692) and having an upper end and a lower end in contact with the lower end of the shock-up bar (694) and the inner bottom of the shock-up sleeve (692).

[0235] At this time, the rear backrest frame (646) has a structure in which a backrest connection frame bar (646CB) is provided at the upper end of the left and right backrest frame bars (646FB), and the lower end of the left and right pair of backrest (650) frames of the rear backrest frame (646) is connected to the left and right pair of lower base bars (612) constituting the base (610) via a hinge, and the rear buffer structure (690) is arranged at a position where it meets the left and right pair of backrest frame bars (646FB) of the rear backrest frame (646). That is, the shock-up sleeve (692), the shock-up bar (694), and the shock-up spring (696) are arranged at a position where they meet the left and right pair of backrest frame bars (646FB) of the rear backrest frame (646), so that the upper portions of the left and right pair of shock-up bars (694) are arranged at a position where they can support the left and right pair of backrest frame bars (646FB) of the rear backrest frame (646) from below.

[0236] When the rear backrest frame (646) is tilted backward from the base (610) based on the lower hinge connected to the base (610) (i.e., the lower hinge connected to the left and right pair of backrest frame bars (646FB) to the lower base bar (612) of the base (610), the shock-up bar (694) is supported by the left and right pair of backrest frame bars (646FB) of the rear backrest frame (646), and the shock-up bar (694) is continuously pressed into the inside of the shock-up sleeve (692) by the load of the rear backrest frame (646) tilted backward, and the shock-up spring (696) is compressed and retained with elastic force, so that there is an effect of reducing the impact force that may be generated when the rear backrest frame (646) is tilted backward from the base (610). Furthermore, there is an effect of preventing in advance the impact force applied to the rehabilitation patient due to the rear backrest frame (646) being suddenly laid down when the rehabilitation patient, whose back is supported by the backrest (650), lies down.

[0237] At this time, in the second embodiment of the present invention, a buffer member (698) such as elastic urethane or sponge is further provided on the upper end of the shock-up bar (694), so that the upper end of the shock-up bar (694) does not directly contact the left and right pair of backrest frame bars (646FB) of the rear backrest frame (646), but rather the buffer member (698) contacts them, thereby preventing impact force or noise that may be generated when the upper end of the shock-up bar (694) directly collides with the backrest frame bars (646FB) when the rear backrest frame (646) is laid down.

[0238] Meanwhile, when the rear backrest frame (646) is raised forward from the base (610) based on the lower hinge connected to the base (610) (i.e., the lower hinge to which a pair of backrest frame bars (646FB) on the left and right are connected to the lower base bar (612) of the base (610), the shock-up spring (696) is compressed and then unfolds by its own elastic restoring force, thereby causing the shock-up bar (694) to be pulled out again to the upper end of the shock-up sleeve (692), thereby enabling the rear backrest frame (646) and the backrest (650) to be switched to a shock-up standby state that absorbs shock when they are tilted backward.

[0239] In addition, the second embodiment of the present invention is characterized by further including an inner chamber (702) provided inside the backrest (650); a plurality of air blowing holes (704) penetrating through the inner and outer surfaces of the front backrest (650) sheet (630) of the backrest (650) and communicating with the inner chamber (702); and an air blowing device (706) connected to the inner chamber (702) of the backrest (650) via a connecting pipe.

[0240] The above air blowing device (706) may be configured as a device having a blowing fan built into a fan case, and may be configured such that an inner chamber (702) inside a backrest (650) is connected to the fan case via a connecting pipe (CP) such as a flexible hose, so that air is introduced into the inner chamber (702) inside the backrest (650) according to the operation of the air blowing device (706) (i.e., rotational operation of the blowing fan) and the air is sprayed into a plurality of air blowing holes (704). At this time, an air inlet hole (650AH) is provided on one side of the backrest (650), and the connecting pipe (CP) is connected to the air inlet hole (650AH), and the connecting pipe (CP) is connected to an air blowing device (706), so that air can enter the air chamber (702) inside the backrest (650) by driving the air blowing device (706) and be sprayed through a plurality of air blowing holes (704). Preferably, a plurality of protrusions and concave grooves are provided on the outer surface of the front backrest (650) sheet (630) of the backrest (650), and a plurality of air injection holes are formed in the concave groove portion, so that cool air sprayed through the air injection holes can be sprayed more smoothly to the back of the rehabilitation patient.

[0241] Accordingly, the second embodiment of the present invention has the effect of allowing the rehabilitation patient to perform rehabilitation exercises in a more comfortable and pleasant environment by continuously cooling the back of the rehabilitation patient while performing rehabilitation exercises by blowing cool air through a plurality of air blowing holes (704) provided in the backrest (650) onto the back of the rehabilitation patient who is sitting with the buttocks on the seat (630) or lying down with the backrest (650) laid down.

[0242] Hereinafter, the third embodiment of the present invention will be described in more detail with reference to the drawings.

[0243] As illustrated in FIGS. 28 to 34, the smart robot health bike system according to the third embodiment of the present invention is composed of a base (800), a seat (900), and a pedaling exercise unit (1000).

[0244] The above base (800) forms the skeleton of the present invention and is composed of a bottom frame (810) that is formed long from front to back on the floor and placed flat, and a front frame (820) that is formed to stand upright in front of the bottom frame (810).

[0245] The seat part (900) is arranged at the rear of the bottom frame (810), and the pedaling movement part (900) is arranged at the front of the front frame (820) and the bottom frame (810).

[0246] Additionally, a display (1100) on which various contents and programs are displayed is provided on the upper part of the front frame (820).

[0247] The above seat part (900) is configured so that the user can sit while looking upward, and is specifically configured with a first guide rail (910), a slider frame (920), a seat (930), a backrest (940), an auxiliary support (950), a headrest (960), and an angle adjustment unit (970).

[0248] The above first guide rail (910) is formed long in the front and back on the upper part of the bottom frame (810), and is composed of two pieces and spaced apart from each other on the left and right.

[0249] The above slider frame (920) is formed in a square frame shape and is mounted so as to be able to slide forward and backward along the first guide rail (910).

[0250] The above seat (930) is the part that supports the buttocks when the user sits, and is fixedly mounted to the slider frame (920).

[0251] The above backrest (940) is mounted on the rear of the seat (930) and the lower part is mounted so as to be rotatable in the front-back direction.

[0252] The above backrest (940) can adjust the inclination by the angle adjustment unit (970), and supports the upper body so that the seated person can exercise while lying down at an angle.

[0253] Additionally, auxiliary supports (950) are provided on both sides of the backrest (940) to prevent the seated person from tilting left and right.

[0254] The above auxiliary support (950) is arranged to be inclined toward the backrest (940) so as to guide the upper body of the seated person toward the center of the backrest (940).

[0255] In addition, a headrest (960) is provided on the upper part of the backrest (940) to support the head from tilting left and right, and the headrest (960) is configured to be able to adjust its position by moving up and down.

[0256] The above angle adjustment unit (970) adjusts the angle of the backrest (940) and is composed of an electric actuator having a piston capable of reciprocating linear movement.

[0257] Specifically, the angle adjustment unit (970) is mounted between the slider frame (920) and the backrest (940), and rotates the backrest (940) according to the linear movement of the piston to adjust the inclination angle of the backrest (940).

[0258] Meanwhile, the pedaling movement unit (1000) is a unit that rotates the legs or arms while the user is sitting on the seat (930), and is composed of a lifting unit (1010), a third guide rail (1020), a fourth guide rail (1030), a left movement unit (1040), a right movement unit (1050), and an electronic clutch (1060).

[0259] The above-mentioned lifting unit (1010) is arranged at the front of the bottom frame (810), and is composed of a second guide rail (1011) formed vertically long along the front frame (820), an lifting frame (1012) mounted so as to be able to slide vertically along the second guide rail (1011), and a lift (1013) mounted on the bottom frame (810) to lift and lower the lifting frame (1012).

[0260] The above lift (1013) is a scissor-type lift (1013) configured by vertically connecting multiple links in an 'X' shape, and is automatically operated up and down by an electric actuator.

[0261] The third guide rail (1020) is formed long in the front-back direction on the upper part of the lifting frame (1012) and guides the left movement unit (1040) to slide in the front-back direction.

[0262] The fourth guide rail (1030) is formed in the same manner as the third guide rail (1020), and is spaced apart from the right side of the third guide rail (1020) to guide the right movement unit (1050) to slide forward and backward.

[0263] Meanwhile, the left movement part (1040) is a part that rotates the user's feet or arms, and is composed of a left body (1041), a left linear motor (1042), a left drive motor (1043), a left crank shaft (1044), a left pedal (1045), a left handle (1046), and a left load motor (1047).

[0264] The above left body (1041) is formed in a long hexahedron shape from front to back, and the left drive motor (1043) is mounted at the front, and the left linear motor (1042) is mounted at the rear.

[0265] The above left body (1041) is mounted to slide forward and backward along the third guide rail (1020).

[0266] The movement of the above left body (1041) is controlled by the above left linear motor (1042).

[0267] The above left linear motor (1042) operates by detecting when the left body (1041) deviates from the initial position through a linear scale and a pinhole sensor.

[0268] That is, when the left body (1041) moves forward from the initial position, the left linear motor (1042) applies a load backward, and when it moves backward from the initial position, it applies a load forward.

[0269] The above left drive motor (1043) is connected to the left crankshaft (1044) and provides rotational force to the left crankshaft (1044).

[0270] The above left crankshaft (1044) is rotatably mounted on the left body (1041), and can be manually rotated by the user or forcibly rotated by the left drive motor (1043).

[0271] The left crankshaft (1044) is provided with the left pedal (1045) and the left handle (1046), so that it can be used not only for the rotational movement of the leg, but also for the rotational movement of the arm when held by the hand.

[0272] Additionally, the rotation strength of the left crankshaft (1044) can be adjusted by the left load motor (1047).

[0273] That is, the left load motor (1047) applies a load to the crank shaft when the crank shaft is manually rotated, so that a certain amount of force must be applied to rotate the crank shaft.

[0274] Meanwhile, the right movement unit (1050) is a unit that rotates the user's feet or arms, similar to the left movement unit (1040), and is composed of a right body (1051), a right linear motor, a right drive motor (1053), a right crank shaft (1054), a right pedal, a right handle, and a right load motor (1057).

[0275] The right movement unit (1050) is identical to the left movement unit (1040) except that the right body (1051) is mounted so as to be movable along the fourth guide rail (1030) and is positioned and operated symmetrically to the left and right of the left movement unit (1040), so a detailed description thereof will be omitted.

[0276] The above electronic clutch (1060) is placed between the left movement unit (1040) and the right movement unit (1050), and the left movement unit (1040) and the right movement unit (1050) can be selectively connected to operate together.

[0277] When the above electronic clutch (1060) is not operating, the left movement unit (1040) and the right movement unit (1050) are separated and can rotate or slide in different directions.

[0278] That is, when the left movement unit (1040) and the right movement unit (1050) are separated from the electronic clutch (1060), the left movement unit (1040) and the right movement unit (1050) slide independently, so that the rotational radii of the left pedal (1045) and the right pedal (1055) may be different.

[0279] Conversely, when the left movement unit (1040) and the right movement unit (1050) are connected by the electronic clutch (1060), the left pedal (1045) and the right pedal slide equally in the forward and backward directions and rotate with the same rotation radius on the same central axis.

[0280] By means of the above-mentioned electronic clutch (1060), the left movement unit (1040) and the right movement unit (1050) can move in various forms.

[0281] Specifically, the smart robot health bike system according to the third embodiment of the present invention can operate in eight modes.

[0282] As illustrated in Fig. 31, when the left movement unit (1040) and the right movement unit (1050) are connected by the electronic clutch (1060), they can operate in a coaxial forward and reverse movement mode in which they rotate in the same direction around the same axis.

[0283] That is, the left movement unit (1040) and the right movement unit (1050) can be rotated in the forward direction or in the reverse direction at the same time.

[0284] In addition, as illustrated in Fig. 32, it is possible to operate in a cross-directional forward and reverse motion mode that rotates in the same direction around the same axis but has different rotation angles.

[0285] That is, the left movement unit (1040) and the right movement unit can be rotated simultaneously in the forward or reverse direction, but the positions of the left crank shaft (1044) and the right crank shaft (1054) can be rotated symmetrically.

[0286] Conversely, when the left movement unit (1040) and the right movement unit (1050) are separated from the electronic clutch (1060), the left movement unit (1040) and the right movement unit (1050) can be rotated independently.

[0287] That is, as illustrated in Fig. 33, the left movement unit (1040) is stopped and only the right movement unit (1050) can operate in a right-side separation forward and reverse movement mode in which it rotates in the forward and reverse directions.

[0288] Conversely, as illustrated in Figure 34, the right movement unit (1050) can also be operated in a left separation forward and reverse movement mode in which only the left movement unit (1040) rotates in the forward and reverse directions while stopping.

[0289] The eight operation modes according to the third embodiment of the present invention described above are not only possible manually, but can also be forcibly operated by the left drive motor (1043) and the right drive motor (1053). Here, the forced operation can assist rehabilitation through forced exercise even when the user's motor ability is reduced.

[0290] In this way, the smart robot health bike system according to the third embodiment of the present invention provides the effect of being able to implement eight different operation modes by enabling the separation and connection of the left movement unit (1040) and the right movement unit (1050) by the electronic clutch (1060).

[0291] Meanwhile, the above-mentioned customized exercise content is a system that provides various programs in conjunction with the pedaling exercise unit (1000), and has a user-customized character.

[0292] The above character is controlled to move in conjunction with the pedaling movement unit (1000).

[0293] Such customized exercise content can enhance exercise and rehabilitation effectiveness by providing users with interest and motivation.

[0294] It will be understood by those skilled in the art that the present invention is not limited to the above-described embodiments, and that various modifications and variations can be made without changing the gist of the present invention.

[0295] Accordingly, the embodiments described above are provided to fully inform a person having ordinary skill in the art of the present invention of the scope of the invention, and should be understood to be exemplary and not limiting in all respects, and the present invention is defined only by the scope of the claims.
