[Previous technology] 10 15 20, most of the load devices for sports equipment are made by hanging multiple weights. Before using sports equipment, users set the number of hanging codes in advance, so that the material is pulled. Hanging these fixed number of knots up and down privately is the strength and strength of sports forging chains, but sports equipment using the yards as resistance is usually very bulky and bulky, and it will make noise when used. Therefore, a load device using the output torque of the motor as a resistance has been developed. 'Figure 1 shows the patent of the Republic of China No. 492885. The load device includes:-a casing 11, which is exposed outside the casing Π and The urging rope wheel 12, a control unit U, and a -resistance unit 14 and a magnetic powder clutch M installed in the housing U can be driven by the user. The control unit it U can be set by the user to control the resistance unit " The direction of the output resistance is constant and the rotation direction of the urging rope wheel 12 is output, and a certain current is output to the magnetic powder clutch 15 to adjust the output to the urging rope wheel ^ The amount of resistance. The output torque of the resistance list $ 14 is sent to the magnetic powder clutch 15. The magnetic powder clutch 15 is controlled by the wheel output control current of the control unit 13 to adjust the resistance of the resistance sheet & Before using the sports equipment, the user sets the amount of exercise resistance on the control unit u, and can perform training and exercise according to the set resistance. No need to adjust the weight, and there will be no weight shift. 5 M252442 Noisy noises. 10 However, after the user sets the exercise resistance, all the processes of exerting force are the same exercise resistance. If the muscles are not stretched enough, exercise with the same forging resistance will easily cause sports injury. Take the leg lift as an example, the user sets 30 kg as the exercise resistance. When the calf starts to lift upright and step forward, the knee is bent, and the knee and ankle joints do not bear any force. Immediately lifting the leg with thirty kilograms as exercise resistance may cause damage to the knee and ankle joints. When the calf lift is close to the level, the muscles are fully stretched. At this time, the calf can be lifted from 35 to 40 kilograms. The exercise resistance of 30 kilograms may be slightly insufficient, and the exercise effect is poor. [New content] Left + Yu, the purpose of this new model is to provide a load device that can change the exercise resistance during the exercise process according to the user's posture and posture. 15 20 The load device of Shiben's new sports equipment includes:-a casing, a force-pumping wheel that is outside the casing and can be rotated by the user's force, and is installed on the casing to measure the force An angle measurement unit for the rotation angle of the f wheel ^ a control unit, a resistance unit, and a magnetic powder clutch. The control includes:-a control panel for a user to input a set value,-receiving the drop control: the input setting value of the board and the output value of the angle measuring unit and transporting it: and with the rotation angle of the force cable A computing component that outputs a different output value and a current controller that outputs a different value as the output value of the computing component changes. The resistance unit includes a motor fixed in the housing and outputting a torque in a direction opposite to the rotation direction of the force applying pulley, and a transmission member driven by the output torque of the motor. The magnetic powder clutch is installed in the 6 M252442 5 housing, and includes a resistance collar that rotates in conjunction with the transmission member, a shaft mounted in the resistance collar, and is rotatably inserted in the force cable shaft. A rotating & electromagnetic coil located outside the resistance collar, the electromagnetic coil is excited by a current of the same magnitude input by the control unit, which causes different interference resistances between the resistance collar and the shaft. The effect of this new 3L is that it can provide different forging chain resistances according to different postures of the user, which not only maximizes the muscle throbbing effect of the Shaw, but also prevents muscles or joints from being injured by sports. [Embodiment] 10 Regarding the foregoing and other technical contents, features, and effects of the present invention, the detailed description of the wealth in the following drawings with reference to the drawings will be clearly understood. 15 20 As shown in FIG. 2, the preferred embodiment of the load device 3 of the new type of sports equipment is assembled in the-sports equipment 2 i, which has multiple use functions and includes a stretching unit 21, a The leg raising unit 22, a jogging unit 23, and a transmission unit 24 that transmits the exercise resistance of the new load device 3 to the stretching, leg raising and jogging units 21, 22, and 23 described above. The transmission unit 24 has a rope 241 that pulls the stretching and leg-lifting units 22 and 22, a plurality of belts 242 that transmit the resistance of the jogging unit 23, and a plurality of pulleys 243 that change the transmission direction of the ropes 241 and the belts 242. . With reference to Figs. 3 and 4, it can be seen that the negative device 3 includes: a casing 4, an urging rope wheel 51 that is exposed outside the casing 4 and can be driven by a user to drive and rotate, and is mounted on the casing. An angle measuring unit 52, a control unit 6, and a resistance unit 7 and a magnetic powder clutch 8 assembled in the casing 4 are used to measure the rotation angle 7 M252442 degrees of the force applying cable 5. The force cable 51 is used for winding a rope 241 of the transmission unit 24. When the user operates the stretching unit 21 and the leg raising unit 22, the rope 241 is pulled and changed by the pulley 243 The urging direction is finally wound on the urging rope wheel 51 to drive the urging rope wheel 51 to rotate. When the running unit is used, the force applying pulley 51 is driven by the belt 242 to rotate. A number of counting grooves 511 are formed on one side of the urging pulley 51 in a plurality of equally spaced radial directions and extend radially and penetrate to the other side for the angle measurement unit 52 to measure the angle. The angle measuring unit 52 uses an optical counting method to sense the passing number of the counting groove of the urging rope wheel, so as to know the rotation angle of the urging rope wheel 51, thereby knowing the user's current posture and the degree of muscle extension. Take the leg lift unit 22 as an example. 'Assuming that the lower leg is lifted from the vertical posture to the horizontal posture, the urging rope wheel 51 can be driven to rotate about 180 degrees for half a circle, and the urging rope wheel 51 is carved every 10 degrees. Counting slot 511. When the angle measuring unit 52 counts to 18, it can be known that the calf has been leveled to a horizontal state. There are many types of equipment for measuring the rotation angle on the market, so the implementation is not limited to the above method. The control unit 6 includes a control panel 61 for a user to input a set value, a control panel 61 which receives the input set value of the control panel 61 and the output value of the angle measurement unit 52 and calculates the value according to the rotation angle of the force application cable η. Aihua outputs a computing component 62 that outputs different output values, a digital analog converter 63 that converts the signal type, and outputs 8 as the output value of the computing component 62 changes: a current controller 64 with different currents, and-controlling the resistance Power drive in the direction of resistance of unit 7 65 ° The control panel 61 can be installed on the front side of the heart and the stretching unit, or on the front side of the jogging unit M, allowing the user to easily control and monitor the exercise resistance value , So its number is not limited to one. -The control panel 61 can input and set the type of the used unit of the sports equipment 2 and the value of the forging chain resistance. The computing unit 62 is a microprocessor, which can store the proportion curves of the different units of leg lifting, stretching and running, and receives the type of movement and the forging chain resistance value output by the control panel 61, and then stores them in comparison. Proportional curve, calculate the exercise resistance value in different postures, and then change the rotation angle of the force cable 51 measured according to the angle measurement sheet & M, and output different forging chain resistance values to that number. The analog converter 63 has a forged chain resistance value which is a digital signal, is converted into an analog signal by the digital analog converter 63, and then transmitted to the current controller 64 to output different currents to the magnetic powder clutch 8. Take the leg lifting as an example. Suppose the user sets thirty kilograms as exercise resistance. When the calf starts to lift upright and step forward, the knee is bent, and the knee and ankle joints are not subjected to any force. The control unit 6 will use the proportion curve of leg lifting as the basis, take 20% of thirty kilograms as the exercise resistance, and gradually increase the percentage as the lower leg is lifted. When the calf lift is close to the level, when the muscles are fully stretched, the percentage can be increased to 120% at this time, that is, about -10 /, A jin 'to optimize the forging effect of the exercise and avoid the occurrence of sports injuries. The above data is only for the purpose of illustrating the effectiveness. The optimal proportion curve of the exercise resistance of various sports units can be obtained from the relevant principle of ergonomics M252442 Z. It is not a feature of the new model, and will not be described in detail. Implementation will not be described. The data is limited. The calculation component 62 can output the current value at that time, and the value can also be expected to be displayed to the editing control panel 61 for corresponding display for the user to monitor. 5 10 The other component 62—the function is to stretch the line of the different units according to the ratio and then cooperate with the output of the angle measurement unit 52—timely output a command to the power driver 65 to drive the resistance unit Direction of output resistance. For example, when the user is using the leg lifting and stretching = 21, the force applying pulley 51 is repeatedly rotated forward and backward, so the different component 62 needs to output a command in time to change the direction of the output resistance of the resistance unit 7 so that The resistance blame is opposite to the rotation direction of the force cable wheel ^. The computing component 62 can also be connected to an external computer_ to download exercise proportion curves of different functions, so that the sports equipment 2 can be used as a model for training muscles of different parts or other functions. 15 20 The resistance unit 7 is fixed in the housing 4 and includes-driven by the power driver 65 and outputting a Tonda 72 'that is opposite to the direction of rotation of the urging pulley 51 and a torque output drive of the motor 72 Transmission member 73: the transmission member 73 has a first pulley 731 and a second pulley 732 respectively mounted on the motor 72 and the magnetic powder clutch 8, and-snare on the first and second pulleys 731, 732 Belt 733. According to the training process of the user, the motor 72 timely provides resistance in the opposite direction, and the resistance is transmitted to the magnetic powder clutch 8 through the first and second pulleys 731 and 732 and the belt plus. The transmission member 73 is commonly seen in general mechanical structures and there are many methods for transmitting torque, so the implementation is not limited to the above 10 M252442 5 10 type. The seat 8 chest powder clutch 8 is installed in the housing 4 and includes a hollow base and two joints. Τ is rotatably accommodated in the base 8G and the outer end is fixed on the second pulley 732 of ^ 73. An inner end and an outer end of the resistance collar 81 are rotatably inserted into the rotating shaft 82m of the axis of the caster 51 on the base 80 and located outside the resistance collar 81 and connected The control unit 6 outputs an electromagnetic coil 83 of a current controller 64, and a certain amount of magnetic powder 84. The resistance collar 81 has a shaft hole 8m, 15 in the shaft 82, and: within the shaft hole 811 The circumferential surface extends radially outward to accommodate the annular magnetic powder groove 812 of the magnetic powder 84. A disk-shaped clutch piece 821 extending radially outward and sliding in the magnetic powder groove 812 is formed on the outer peripheral surface of the rotating shaft 82 opposite to the rotating shaft 82. The electromagnetic coil 83 directly corresponds to the magnetic powder tank of the resistance collar 81. Outside, when the current controller 64 of the control unit 6 has no output current, the toner is loosely dispersed in the toner tank, and the clutch The plate 82 can move in the magnetic powder tank 812 without interference resistance. When the current controller 64 outputs When flowing to the solenoid 83 so energized, causes the magnetic material
固結於該磁粉槽812内並使該離合片821被固結之磁粉料 夾阻於該磁粉槽812内，致使該阻力套環81與該轉軸82 20 間產生一干涉阻力，而電流越大該干涉阻力越大。由此可 知，該磁粉離合器8可將該阻力單元7的輸出阻力傳送至 該施力索輪5 1上。該磁粉離合器8非本新型之特徵構造， 其詳細構造在此不再多作說明。 藉此，該控制單元6可依照使用者之設定值與人體工 11 M252442 5 10 學之比例曲線推算出使用者各 ,α · π 士 m剎緣過程中最佳的锻鍊 阻力，並藉由該控制單元6之輸 莉j Ώ龟々,L大小调整阻力單元 7傳送至該施力索輪51的輪出 曰从 曰7輪出阻力大小。可使鍛鍊的效果 取佳，又避免使用者受到運動傷害。 …歸納上述、，本新型運動器材之負荷裝置3藉由該控制 早凡6可下載並儲存各種運動過程之比例曲線，並依據使 用者之-又疋值推异出各種動作姿勢時的最佳的鍛鍊阻 力，f以該磁粉離合器8將該阻力單元7之輸出阻力依照 控制早7G 6運算出之數值對應地傳送至該施力索輪w 上’可使鍛鍊的效果最佳’又避免使用者受到運動傷害。 故確實能達到本新型之目的。It is fixed in the magnetic powder tank 812 and the clutch sheet 821 is sandwiched in the magnetic powder tank 812 by the consolidated magnetic powder material, so that an interference resistance is generated between the resistance collar 81 and the rotating shaft 82 20, and the larger the current The greater the interference resistance. It can be seen from this that the magnetic powder clutch 8 can transmit the output resistance of the resistance unit 7 to the urging sheave 51. The magnetic powder clutch 8 is not a characteristic structure of the present invention, and its detailed structure is not described in detail here. In this way, the control unit 6 can calculate the optimal forging chain resistance for each user, α · π ± m according to the ratio curve between the user's set value and the ergonomic 11 M252442 5 10 study, and by The control unit 6 loses the resistance, and the L-size adjusting resistance unit 7 transmits the resistance to the wheel-out force of the force applying pulley 51. It can improve the effect of exercise, and prevent users from being injured by sports. … In summary, the load device 3 of this new type of sports equipment can download and store the proportional curves of various sports processes through this control, and according to the user ’s value, the best when various action postures are deduced. The exercise resistance, f is the magnetic powder clutch 8 and the output resistance of the resistance unit 7 is transmitted to the force rope wheel w in accordance with the value calculated by the control 7G 6 in the early stage. Injured by sports. So it can really achieve the purpose of this new model.
