Description of the invention: [Technical field to which the invention pertains] In particular, a muscle force The present invention relates to a tension transmission device for a muscle training device. [Prior Art], Guan Guanbu uses a kind of muscle force trainer i that uses electric power to generate resistance as an example. 'The main part includes a frame n, which is mounted on the frame u and can be left-right-sliding-pulling... 2, and a transmission device 设置 disposed in the frame U. The tension band 12 has an urging end i2i formed at one end and being responsive, and a aligning end 122 formed at the other end. The transmission device 13 has a tension wheel 131 coupled to the tension band η linkage end 122, and a motor 132 that can drive the tension wheel 131 to rotate. The motor 132 drives the tension wheel 1 3 1 to wind up the tension band 12. When the user pulls the pulling end 121 of the tension band 12, the motor 132 retracts the force of the tension band 12 through the urging wheel 131, and the user has a resistance to the shape, thereby pulling and releasing the leader. In the process of pulling the belt η, the effect of training muscle strength is achieved. However, although the muscle training device i can be placed by a resistance (for example, a magnet seat is placed under the tension #131, and a magnetoresistance effect is generated on the tension wheel (3)), the purpose of adjusting the resistance is achieved, but ", the size of the resistance" and the effect of the muscle strength training, it is completely unknown, in this case 'the adjustment of the resistance is empty and meaningless, and because the tension and the electric power are in the opposite direction', therefore, when the user Pulling the force belt 12 causes the tension wheel 131 to reversely rotate the motor 132, causing the motor 132 to rotate 5 at a time and a first intermediate gear "wheel 55" for transmitting power. The distal first intermediate gear 54 is coupled to the primary and secondary teeth. The intermediate gear 55 is coupled to the driven gear (four). Wheel 52^. The first transmission unit 6 and the ancient + second intermediate gear 54, 5 " frame 21 are inserted with the first and fourth 55's wheel seats 6〇, and the driven gear 52_#_μ is again in the wheel A tension band 62 in the seat 60 and 21 =: - the wheel 61, and the frame mounted on the frame 431 ^ 1 wheel 6 ^ heart _ speed wire group 5 in conjunction with the pull. The tension band 62 has a leading end 621 formed on a pull and a trailing end 622 formed on the other side. ^ and ^ Xuan pull wheel 61 - the number 7 has a torque sensor 71, - microprocessor", digital / analog converter 73, a control circuit 74, - drive, with = panel 76. The sense of torque The detector is placed on the driving shaft 51 and the torque of the driving shaft 51 is measured. The microprocessor communicates with the torque sensor 71 through the vertical/analog converter 73, and transmits through the working circuit. 74. The driving circuit 75 can program the resistance unit buckle. The control panel 76 is used to input related setting values during muscle strength training. Referring to FIG. 2 and FIG. 5, the following is the muscle strength training for the present invention: The action flow of the tension transmission device is combined with the steps of the embodiment to describe the following step 81: starting the strength training device 2. Step 82: Select the muscle strength training mode through the control panel 76. Step 83. Input the pulling force through the control panel 76 Step 84: The microprocessor π controls the magnitude of the current of the electrical component 421 according to the tension setting value, and adjusts the magnitude of the magnetic force generated by the electrical component 421, so that the electrical component 421 attracts the metal component 422, thereby Metal member 422 will pass through the shaft 41 The clutch member 432 is displaced along the shaft hole 311 of the transmission shaft 31 to the right side of the drawing, so that the clutch member 432 is frictionally contacted with the first disk surface 431a of the disk holder 431 to form a linkage. Step 85: The motor 3 is driven by its transmission shaft 3丨Synchronously driving the shaft 41 to rotate in one direction, so that the clutch shaft 4 is rotated during the rotation, and the clutch member is synchronously rotated with the disc holder 431, thereby rotating the clutch #432 and the disc holder 431. 'The power will be transmitted to the tension wheel 61 through the reduction gear set 5, so that the tension pulley 61 retracts the tension belt 62 to a predetermined length. vStep 86_ When the user pulls the tension belt 62 along the left side of the drawing When the tension end is 621, and the pulling force is greater than the frictional resistance of the disc holder 431 and the clutch member 432, the tension wheel 61 drives the disc holder 431 through the reduction gear set 5, so that the disc holder 431 is idled on the clutch member 432. It is worth mentioning that the magnitude of the frictional resistance generated by the disk holder 431 and the clutch member 432 is determined by the magnetic attraction force of the electric flux 421 and the metal member 422. Therefore, the pulling force of the user pulling the tension band must be overcome. The aforementioned frictional resistance. Step 87: The torque sensor 71 will In the step %, the torque and the maximum torque value of the drive shaft 51 are transmitted back to the microprocessor 72 through the digital/analog converter 73. Step 88: The microprocessor 72 trains according to the selected muscle strength. The mode and the maximum torque value of step 87 are used to calculate the appropriate resistance. Step 89: The microprocessor 72 controls the current of the electrical component 421 through the control circuit 74 and the driving circuit 75 to set the electrical component. Figure 1 B _ .
