[0032] The moving components of the bidirectional isokinetic resistance output structure include a motor bracket 8 and a motor 10 mounted on the partition 22. The motor 10 is a motor that runs bidirectionally in forward and reverse, corresponding to the output directions of centrifugal and centripetal respectively. The motor 10 is mounted on the motor bracket 8. The output shaft of the motor 10 passes through the box body 1 and is connected to the moving arm assembly 14. The moving arm assembly 14 is located outside the box body 1, and a cross arm 18 is provided at the lower end of the moving arm assembly 14. That is to say, the output mode of this embodiment is that the motor 10 directly drives the resistance generating device connected to the moving arm assembly 14 to generate centripetal or centrifugal force.

[0033] As Figure 2 shown, the moving arm assembly 14 is a split structure up and down, divided into an upper moving arm split 9 and a lower moving arm split 7. A jack 17 is provided on the arm body of one split, and a corresponding adjustment gear hole 16 is provided on the arm body of the other split. The upper moving arm split 9 and the lower moving arm split 7 are joined together as a whole by inserting the jack 17 into the adjustment gear hole 16 corresponding to it, so as to realize the free step of the length of the moving arm assembly 14 and allow the best position to be adjusted according to the specific needs of the exerciser.

[0034] The seat includes a connecting bracket 6. One end of the connecting bracket 6 is mounted on the side of the box body 1. A seat cushion 5 and a seat backrest 3 are mounted on the connecting bracket 6. Heart rate detection devices for detecting heart rate are mounted on the handlebars 4 installed on both sides at the lower end of the seat backrest 3.

[0035] Working process:

[0036] First, the exerciser makes fine adjustments through the control terminal 2 according to his own needs. At the same time, the position adjustment of the moving arm is realized through the regulator 15;

[0040] Working process:

[0041] First, the exerciser makes fine adjustments through the control terminal 2 according to his own needs. At the same time, the position adjustment of the moving arm is realized through the regulator 15;

[0042] Then, the exerciser sits on the seat cushion 5, steps on the cross arm 18 with both feet, presses the start / stop button 21 or swipes the card in the card swiping area 19. The motor 10 starts. The exerciser holds the handle 4 with both hands. The motor 10 drives the second transmission wheel 24 to rotate. The second transmission wheel 24 drives the first transmission wheel 12 to rotate through the transmission medium 13, thereby driving the moving arm assembly 14 to rotate, realizing the speed change and resistance transmission of the motor 10, and thus driving the legs of the exerciser to start moving.
