BMW 3 Series Smart Open and Close Electric Door Liftgate with Intelligent Sensing

What is the electric tailgate?

An electric tailgate, also known as a power liftgate or automatic tailgate, is a feature commonly found in modern vehicles that allows the rear door or hatch to be opened and closed automatically with the push of a button or through a sensor-based activation system. It is typically powered by an electric motor and controlled by the vehicle's electrical system.

The electric tailgate offers convenience to vehicle owners by eliminating the need to manually open or close the rear door or hatch. This feature is particularly useful when carrying heavy items or when accessing the cargo area in situations where hands may be occupied, such as when holding groceries or luggage.

The operation of an electric tailgate can vary depending on the vehicle model and manufacturer. In most cases, the tailgate can be opened or closed by pressing a button on the key fob, interior control panel, or using a sensor-based system that detects foot movement under the rear bumper. Some vehicles also provide customizable height settings for the tailgate opening to accommodate different parking spaces or user preferences.

In addition to the convenience factor, electric tailgates often include safety features to prevent injury or damage. For example, they may have sensors that can detect obstacles, such as a person or object in the path of the closing tailgate, and automatically reverse the operation to avoid accidents.

Why are we choose hands-free smart liftgate?

Of course, this is tremendously convenient during those one or two times a month when your hands are full with breakable items, such as glass dinnerware, or baby sheep. Allow me to provide a few examples.

The working principle of the strut:

When the motor is not working, the resistance of the screw rod, the resistance of the motor gear box, the spring force and the gravity of the door form a balance torque to keep the door hovering at any position.

When the motor is working, the motor torque breaks the balance. According to the motor torque direction, the strut performs telescopic movement to drive the door to open and close.

Features:

Low noise, stable and reliable. Combined with the controller, the height and anti-pinch functions can be set, and the installation is simple.Intelligent double Hall automatic fulcrum has adjustment protection to achieve comfortable and smooth door opening and closing.

How can we open the electric tailgate?

There are several ways to open an electric tailgate, depending on the specific vehicle and its features. Here are some common methods:

Key Fob: Many vehicles with electric tailgates include a dedicated button on the key fob. Pressing the corresponding button on the key fob will activate the tailgate, causing it to open or close automatically.

Front Button: Inside the vehicle, there is typically an interior control panel, often located on the driver's side door or center console. This panel will have a dedicated button or switch specifically for opening and closing the tailgate. Pressing the button or activating the switch will trigger the automatic operation of the tailgate.

Rear Button: Some vehicles have an exterior button or touchpad located near the tailgate itself. Pressing this button will initiate the opening or closing of the tailgate. This is useful when approaching the vehicle from the rear and you want to open the tailgate without entering the vehicle.

Foot Gesture/Sensor: Certain electric tailgates offer hands-free operation using sensor-based systems. These systems detect foot gestures or movements under the rear bumper or designated area. By waving your foot or performing a specific motion, you can trigger the tailgate to open or close without physically touching anything.
