Manufacturing technology of electric massage bed

Technical introduction of electric massage bed:

The drive circuits of all motors in the existing electric massage bed control system are basically controlled by a control chip. This centralized control method has certain hidden dangers. When a circuit is faulty, it may cause the entire control system. None of the functions can be used. For example, when the circuit that drives the vibration motor fails and causes a short circuit, the entire electric massage bed control system will stop working, causing the electric massage bed to lose its massage function. The control method of this electric massage bed is too simple, and the flexibility in use is not enough. Based on the above technical problems, it is necessary to design a new control circuit for an electric massage bed and an electric massage bed.

Technical realization ideas:

The purpose of the technology is to provide a control circuit for an electric massage bed and an electric massage bed to solve the technical problem of wireless independent control of the electric massage bed motor. In order to solve the above technical problems, the present technology provides a control circuit for an electric massage bed, including: at least one motor control circuit; a first wireless module is provided in the motor control circuit to receive a wireless control signal, and the motor control Each output end of the circuit is suitable for connecting to the control end of the corresponding motor in the bed. Further, the motor control circuit includes: a motor processor, and a motor drive circuit electrically connected to the motor processor; wherein the motor drive circuit is a vibration motor drive circuit and / or a push rod motor drive circuit. Further, the first wireless module includes: a wireless chip and a power-off circuit; wherein the D end of the MOS tube in the power-off circuit is connected to the power supply, the S end is connected to the power supply end of the wireless chip, and the G end is connected to the motor through a resistor The motor processor in the control circuit is connected; that is, when the first wireless module does not work within a preset time, the motor processor outputs a low level to turn off the MOS tube and cut off the power supply of the first wireless module. Further, the push rod motor driving circuit further includes: two micro switches connected in the motor drive circuit, and the two micro switches are suitable for telescopically limiting the motor push rod.
