As shown in fig. 1 and 2, a treadmill includes a frame 1, a reduction motor 2, a pedal 3, a control system 4, a control device 5, and a VR system (not shown).
The frame 1 is a bearing main body of the treadmill, and specifically comprises a main body support 11, a speed reduction motor support 12, a holding rod and a handle. Specifically, the speed reducing motor 2 is installed in the main body support 11, and a shaft of the speed reducing motor 2 extends out to the left and right sides of the main body support 11; the speed reducing motor support 12 is arranged on two sides of the main body support 11, and a crankshaft of the speed reducing motor 2 is arranged on the speed reducing motor support 12. The crankshaft of the speed reducing motor 2 is connected to a transmission device 6 and is connected to the pedal 3 through the transmission device 6, and the transmission device 6 comprises a bearing, a crank and the like; the lower end of the holding rod 13 is mounted on the front side of the main body bracket 11 and extends upwards; the middle of the handle 14 is mounted to the upper end of the holding rod 13. The pedals 3 are used for simulating the walking action of the human body through the transmission device 6. The guide wheel 7 is arranged below the pedal 3 to guide the pedal 3 to run.
Wherein, the VR system is used for the running scene when the simulation motion to the cooperation user is run. Different field environments are simulated in the movement, and interestingness and challenge are improved.
When the speed reduction motor 2 is under the action of external force, namely the pedal 3, and the actual rotating speed of the motor shaft is not within the range of the normal rotating speed of the speed reduction motor 2, the inductive coil generates induced current under the action of the pedal 3, and the induced current generates electromagnetic damping in the running direction of the pedal 3.
Wherein, as shown in fig. 3, the control system 4 is connected to the reduction motor 2 and is mounted on the main body support 11. The control system 4 is used for controlling the operation of the reduction motor 2. The control system 4 comprises a single chip 41, an adjusting resistor 42 and an integrated circuit connected to the single chip 41, wherein the integrated circuit comprises an angular velocity sensor and a light sensing counter 413.
Specifically, the light sensor counter 413 is disposed at the crankshaft of the reduction motor 2 to measure the number of turns of the crankshaft of the reduction motor 2. The angular velocity sensor is arranged at a crankshaft of the reduction motor 2 and used for detecting the rotating speed and the rotating direction of the reduction motor 2.
Specifically, the single chip 41 is configured to set an operation program of the reduction motor 2 and execute the operation program to control the operation of the reduction motor 2; the running programs comprise an active running program and a passive running program. In this embodiment, the single chip 41 includes a movement direction determination unit, a resistance adjustment unit, an adjustment resistor 42, a second communication unit, a heat consumption calculation unit, a processing unit, and a display 412. The motion direction judging unit is used for judging the real-time rotation direction of the reducing motor 2, and the processing unit adjusts the rotation direction of the reducing motor 2 according to the real-time rotation direction and the running program. If the deceleration motor 2 rotates counterclockwise, the corresponding human body movement is a backward movement, and if the user needs to change the backward movement into a forward movement, the control device 5 sends a control instruction to the control system 4, and the processing unit controls the deceleration motor 2 to change from counterclockwise rotation to clockwise rotation.
Under the active operation program, the single chip 41 is used for cutting off the external current of the speed reducing motor 2; the speed reducing motor 2 is provided with an inductance coil and used for generating induction current under the action of the movement of the pedal 3, and the adjusting resistor 42 is connected between the speed reducing motor 2 and the singlechip 41. When the rotating speed of the reduction motor 2 is not within the preset value range, the resistance adjusting unit is configured to adjust the resistance value of the adjusting resistor 42 to adjust the resistance value of the electromagnetic damping, that is, the single chip 41 adjusts the resistance value of the resistor according to the duty ratio of the induced current to adjust the resistance value of the electromagnetic damping. That is, the smaller the resistance value of the adjustment resistor 42, the larger the induced current, the larger the resistance of the electromagnetic damping, and the more heat is consumed by the movement of the human body. The faster the induced current is generated, i.e., the smaller the duty cycle, the larger the induced current, the greater the resistance of the electromagnetic damping, and the more heat is consumed by the human body movement.
The heat consumption calculating unit is configured to calculate the heat consumed by the human body under the active operation program, specifically, according to a set program, an algorithm provided in this embodiment is as follows: in the present embodiment, jogging is set to one hour =600kcal (one kilocalorie) for one minute =100 revolutions; the rotation speed 6 (kilocalories) per minute is base 100. Active mode heat consumption calculation: percent resistance (turns/(base 100)) base 6, as shown in table 1 below.
Table 1: and (3) the heat consumed in 1 minute by each resistance gear under the active operation program is calorie.
Resistance (gear) resistance (percentage) speed (number of turns) time (minute) calories
00 100% 100 1 6
01 110% 100 1 6.6
02 120% 100 1 7.2
02 120% 50 1 3.6
Under a passive operation program, the control system 4 provides current for the reduction motor 2, and the control system 4 is used for controlling the rotation speed of the reduction motor 2. When the running action of the human body moves along with the pedals 3, the rotating speed of the speed reducing motor 2 is within the normal rotating range, the induction coil does not generate induction current, and no electromagnetic damping exists. When the running speed of the human body is increased, the rotating speed of the pedals 3 is increased, the actual rotating speed of the speed reducing motor 2 is higher than the normal speed, at the moment, the induction coil generates induction current, the induction current generates electromagnetic damping, the force used by the human body is increased, and the consumed heat is increased. The heat consumption calculating unit is used for calculating the heat consumed by the human body under the passive running program, specifically, calculating according to a set program, and the embodiment provides an algorithm as follows: passive mode heat calculation: the active mode motion consumption is 5 times that of the passive mode, then the heat consumption is: percent resistance (turns/(100 base)). base 6/5. As shown in table 2 below.
Table 2 shows the heat consumed in calories for each resistance gear in the passive operating program over 1 minute.
Base calories from resistance (gear) resistance (percent) speed (turns) time (minutes)
00 100% 100 1 6 1.2
01 110% 100 1 6.61.1
02 120% 100 1 7.2 1.44
02 120% 50 1 3.6 0.72
