In the world of automotive technology, DC car door actuators have revolutionized the way we interact with our vehicles. These small yet powerful devices play a crucial role in ensuring the smooth and efficient operation of car doors. With their push-pull force of up to 6 kilograms and flexible stroke distance of 21mm, DC car door actuators are designed to provide universal fitment and high temperature resistance, making them a versatile and reliable choice for car owners. In this comprehensive guide, we will explore the features, installation process, and benefits of DC car door actuators, shedding light on their importance in the automotive industry.
Car Door actuator Working Principle
Electromagnetic type of cart door Actuator Principle: It consists of electromagnetic coils. When the solenoid coil is energized, it generates a magnetic field, and the electromagnetic force makes the armature move, driving the connecting rod to realize the locking and unlocking of the car door. For example, when the lock signal is sent, the current passes through a specific coil, generating an electromagnetic force that pulls the armature to lock the door latch.
Motor Actuator type Principle: Motors, such as DC motors or permanent magnet motors, are used. When the motor rotates, the rotational force is transmitted to the door lock mechanism through reduction gears and transmission rods. The motor rotates in different directions to control the opening and closing of the door lock. For instance, when receiving an unlocking signal, the motor rotates in a certain direction to drive the lock cylinder to rotate and release the door latch.
Structure
Electromagnetic Actuator Structure: It mainly includes electromagnetic coils, armatures, springs, and connecting rods. The electromagnetic coil is the core component that generates electromagnetic force. The armature moves under the action of electromagnetic force, and the spring is used to reset the armature. The connecting rod transmits the movement of the armature to the door lock mechanism.
Motor Actuator Structure: It is composed of a motor, reduction gearbox, transmission rod, and position sensor. The motor provides power, the reduction gearbox reduces the speed and increases the torque, the transmission rod transmits the power to the door lock, and the position sensor is used to detect the position of the door lock and feedback to the control system.
