Detailed Description
In order to more clearly illustrate the technical solution of the present invention, the drawings used in the description will be briefly introduced, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other embodiments can be obtained according to the drawings without inventive labor.
As shown in fig. 1 and 2:
a servo motor 7 is fixedly arranged on a rack 10, the servo motor 7 adopts an angle motor or a non-angle motor, an output shaft of the servo motor 7 is connected with an input shaft of a servo motor reducer 8 fixedly arranged on the rack 10, an output shaft of the servo motor reducer 8 is connected with a small belt pulley 2, the servo motor reducer 8 is designed to reduce the speed in a ratio of 1: N, and when N is 1, the servo motor reducer 8 is not needed by the system.
A big belt pulley 1 is pivoted on a machine frame 10, a belt 11 is wound on the big belt pulley 1 and the small belt pulley 2, and a tension pulley 3 is propped against the outer side surface of the belt 11. The frame 10 is pivoted with a fixed pulley 4.
The steel wire rope 5 is an operation rope, and the top end of the steel wire rope 5 is connected with an operation end such as a handle 14.
One end of a transmission belt 6 is fixedly connected with the bottom end of the steel wire rope 5, the other end of the transmission belt is fixedly connected with the large belt pulley 1, and the transmission belt 6 is wound on the fixed pulley 4.
A position limiter 12 is arranged on a machine frame 10 below the bottom end of the steel wire rope 5, the position limiter 12 is connected with a servo motor controller 9, or an infrared or light or electromagnetic position sensor 13 is arranged at a position, corresponding to a handle 14, of the machine frame 10, and the position sensor 13 is connected with the servo motor controller 9.
The stopper 12 may be a pure mechanical structure or an electronic stopper, if the pure mechanical structure is not connected to the motor controller 9, the stopper 12 is electrically connected to the motor controller 9 if the electronic stopper is used, and the stopper 12 is the electronic stopper and has the same function as the position sensor 13.
Servo motor controller 9 connects and control servo motor 7, and servo motor controller 9 can the connection control instrument, also can connect WIFI, and during the connection control instrument, the user passes through control instrument input setting value, and when connecting WIFI, the user can pass through cell-phone APP input setting value, sends for servo motor controller 9 through WIFI.
In actual use:
the servo motor controller 9 controls the servo motor 7 to generate counterclockwise or clockwise torque, and the torque of the servo motor 7 is transmitted to the handle 14 through the servo motor reducer 8, the small belt pulley 2, the belt 11, the large belt pulley 1, the transmission belt 6 and the steel wire rope 5. The tensioner 3 functions to tension the belt 11.
The user grasps the handle, and when the stretching force is larger than the torsion of the servo motor 7, the stretching action is carried out; when the stretching force of the user is smaller than the torsion of the servo motor 7, the recovery action is performed.
As shown in fig. 3:
the system enters an initial state after being started;
if the state is not the initial state, the servo motor 7 is operated to return to the initial state, and if the state is the initial state, the user performs stretching, and if the stretching state is not stopped, the stretching is continued, and if the stretching state is stopped, the servo motor 7 performs recovery.
The servo motor controller 9 converts the resistance value set by the user into a torque value corresponding to the servo motor 7, the servo motor 7 acts on the movement direction of the instrument driven by the handle 14 clockwise or anticlockwise to generate a resistance value corresponding to the set value, and the user grasps the handle 14 to stretch with force to overcome the resistance value for exercise;
