Intelligent Doorbell Gear Motor Solution

The control function of the geared motor further optimizes the effect of the smart doorbell, prolongs the life of the doorbell, thereby reducing the possibility of outdoor electronic products being stolen and avoiding the user’s property loss.

Project Background

Nowadays, with the development of science and technology, more and more scientific and technological achievements are used in our daily lives. People’s lives are moving in the direction of intelligence. A large number of modern technologies are used in our daily lives, which not only improves our standard of living but also has created a safer and smarter living environment for us. Smart homes have gradually entered the market, including intelligent doorbells.

The Principle of the Smart Doorbell

The smart doorbell is inStalled on the base of the seat cavity formed by the back cover and the front cover. The seat cavity is provided with a motor. The Output end of the gear motor is connected to the gear rack. The two ends of the gear rack are respectively sleeved in the card position and the card slot. The gear bar is horizontally fixed on the back cover through the wheel bar fixing plate, and a PCB board is also inStalled in the seat cavity. Various functional modules are integrated on the PCB board, including a control module, a wireless signal transceiver module, and a power supply module.

When the doorbell needs to be disassembled, the user sends a disassembly instruction to the control module through the authorized intelligent mobile terminal. The control module drives the motor to work. The gear starts to rotate with the gear motor, and the gear bar moves horizontally under the drive of the gear, thus making the strip exit from the card slot, and the user can take out the doorbell.

When inStalling the doorbell, the user correctly places the doorbell on the doorbell base and sends a lock command to the control module through the authorized intelligent mobile terminal. The control module drives the motor to work, and the gear starts to rotate with the gear motor. The gear bar moves horizontally under the drive of the gear so that the gear bar is inserted into the card slot.  And the doorbell is locked on the base of the doorbell.

 It can be seen from the working principle of the smart doorbell that the geared motor plays a controlling role in the smart doorbell. Kinmore provides motor control solutions for smart doorbells.
