Description

Technical Field

[0001] The utility model relates to the technical field of cervical vertebra massagers, in particular to an intelligent cervical vertebra massager control device. Background Art

[0002] As an increasingly popular medical and health device, cervical massagers provide people with an effective means to relieve neck pain and fatigue; with the advancement of technology, the design and functions of these massagers have become more complex and advanced, among which the electronic control part plays a core role.

[0003] Traditional cervical massagers are mainly based on brushless motors, which are popular among users in the market due to their low noise, long life and high torque. However, the drive of brushless motors is relatively complicated, and usually three Hall elements need to be placed on the brushless motor, and these Hall signals are read by the driver board or control board to drive the motor.

[0004] In the market, there are two main PCBA board designs for known cervical massagers. The first design separates the motor board, the charging and control two-in-one board, and the key board, which makes the production and assembly process complicated and costly. The second design only places the Hall plate on the brushless motor, and the rest of the drive parts are integrated into a three-in-one board. Although this design simplifies the software communication part, it still requires up to 8 connecting wires, which also increases the production complexity and the risk of poor connection. In addition, both designs require communication between the MCU main control modules to coordinate the work of each module, which not only increases the complexity of the software, but may also cause communication failures and affect the normal operation of the massager.
