Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a control system for motor telescopic massage includes: control switch 1 and MCU (little the control unit) 2, control switch 1 is connected with motor 6 with the start-up or the stop of control motor 6, be connected with massage portion 7 on the motor 6, MCU2 is connected with a plurality of motors 6 and controls a plurality of motors 6 singly or stretch out and draw back in proper order according to the settlement order in proper order, when control switch 1 opens and makes motor 6 start, the sensor that is connected to motor 6 among MCU2 detects the sinusoidal induction electromotive force that motor 6 both ends produced and sends MCU2 after through the conversion, MCU2 obtains the stroke position of motor 6 according to the signal and directly controls motor 6 to retract to the bottommost after immediately controlling motor 6 and stretching, reciprocal above-mentioned process is massaged in order to promote massage portion 7 reciprocating motion, motor 6 closes or control switch automatic shutdown motor 6 after the certain time through control switch 1 manual.

In addition, after the control switch 1 is manually closed, the motor 6 automatically retracts to the bottom end.

In addition, the control switch 1 is automatically closed after the motor 6 runs for 30 minutes, and the motor 6 stops running and retracts to the lowest end.

In addition, sinusoidal induced electromotive force generated at both ends of the motor 6 is transmitted to the MCU after passing through the low pass filter 3, the AC/DC converter 4, and the comparator 5 in sequence.

In addition, the motor 6 is a brushed dc motor.
