Car Tailgate Pacemaker
How Car Electric Tailgate Works?
Electric tailgates, commonly known as power liftgates, enhance vehicle convenience by automating the opening and closing of the rear trunk. These systems typically utilize electric motors, often DC gear motors, to drive the tailgate’s movement. Activation can be achieved through various methods, including pressing a button on the vehicle, using a key fob, or employing hands-free sensors that detect a foot movement beneath the rear bumper.

The electric tailgate system comprises several key components:
Electric Motor: Provides the necessary torque to move the tailgate.
Transmission Mechanism: Converts the motor’s rotational motion into linear movement, facilitating the tailgate’s opening and closing.
Control Unit: Processes input signals from the user (e.g., button presses or sensor activations) and manages the motor’s operation accordingly.
Safety Sensors: Detect obstacles in the tailgate’s path to prevent injury or damage by stopping or reversing the movement if an obstruction is detected.
Manual Override: Allows for manual operation of the tailgate in case of system failure or when the vehicle’s battery is depleted.
The integration of these components ensures that the electric tailgate operates smoothly, providing users with a seamless and efficient experience.
How DC Gear Motor Works on Car Electric Tailgate?
In automotive electric tailgate systems, DC gear motors are essential for automating the opening and closing of the trunk. These motors are typically integrated into electric strut assemblies, which consist of an inner tube housing the motor and gearbox, and an outer tube containing a threaded nut. When activated, the DC gear motor drives a threaded spindle within the inner tube, causing the nut in the outer tube to move. This movement extends or retracts the strut, thereby opening or closing the tailgate. The gear mechanism ensures that the motor operates smoothly and efficiently, providing the necessary torque to handle the weight of the tailgate. Additionally, the system often includes safety features such as obstacle detection to prevent injury or damage during operation.

Advantages of DC Gear Motor Working in Car Electric Tailgate?
DC gear motors are integral to automotive electric tailgate systems, offering several advantages:
High Torque Output: They provide the necessary torque to lift and lower heavy tailgates, ensuring smooth operation.
Compact Design: Their small size allows for easy integration into the vehicle’s structure without compromising space.
Energy Efficiency: DC gear motors consume less power, contributing to overall vehicle energy efficiency.
Low Noise Operation: They operate quietly, enhancing the user experience by minimizing noise during tailgate movement.
Durability: Designed for automotive applications, they are built to withstand harsh conditions, ensuring long-term reliability.

A DC gear motor, also known as a reduction motor, is a combination of a DC motor and a gearbox. It is driven by the use of direct current. In most cases, a gearbox is added to limit the speed of the motor shaft and increase the output torque of the motor. The most common DC gear motors are the 12V DC gear motor and the 24V DC gear motor.

Gear motor solutions for automatic door
DONGMING MOTOR specializes in automatic door operator motors and gear motors. We have provided DC gear motors for the commercial automatic door operator industry for years and our success lies in our long-standing focus on quality and value. We focus on four commercial door operator applications: Slide Door Operators Swing Door Operators Overhead Door Operators Revolving Door Operators Slide Door Operators Electric sliding doors found in public buildings are designed to add customer convenience. Electric sliding doors on elevators are a requirement. Both types of electric sliding doors must operate quietly and efficiently, relying on the power behind its electric gear motor inside. Typical electric sliding doors are interior doors and may not need the IP ratings of exterior door use. Swing Door Operators Hospitals, clinics and retail locations will typically use an electric swing door. A rugged and durable gear motor that is quiet in operation is just as important as its longevity. Power Electric ensures the highest quality, durability and reliability and we work to continuously maintain and improve. Overhead Door Operators Also commonly referred to as garage door openers, we focus on commercial-grade operators for motor and gear motor applications. Motors and gear motors for these heavy doors must operate with precise torque and efficiency, be extremely reliable and durable and able to withstand environmental demands. Learn more on IP Ratings to discover what it means and contact us to discuss what’s right for your needs. Revolving Door Operators Electric revolving doors save energy by reducing the drafts of air that escapes through swing or slide doors. These types of doors also improve traffic flow in commercial areas. Revolving doors must be powered by a gear motor that meets energy efficient standards as well as have a long lifespan. Contact us to talk through how your revolving door operators can benefit from housing a Power Electric-sourced gear motor. DONGMING MOTOR works with automatic door operator equipment companies throughout the world, assisting customers with motor and gear motor solutions for their projects. Connect with our in-house engineering experts for custom electric motors or find support choosing the right product for your electric door operator applications by calling 86-755-2973-5896.
