About the working principle and advantages of electric tailgate lift

An electric tailgate lift is a device that automatically controls the opening and closing of a car's tailgate (or trunk door) through electric drive. This greatly improves the convenience and comfort of use, especially when both hands are full of things or the physical ability to manually operate the tailgate is limited. The following are some information about the working principle, advantages and market status of electric tailgate lifts.

1. Working principle:

(1) Electrical part: mainly includes DC motor, lifting control switch, DC power supply, fuse and connecting cable. The electric tailgate lift can activate the control system through buttons in the car (usually located near the driver's seat or on the dashboard), remote control keys or external sensors (such as kick sensors), or even sensors that detect kicking movements under the rear bumper, depending on the function of the vehicle. The current drives the motor to rotate forward or reverse. Once activated, the motor will power the lifting mechanism, which will raise or lower the tailgate smoothly and quietly. Its operating speed is usually controlled to ensure safe and smooth movement.

(2) Mechanical: The motor is connected to a transmission or directly to a lifting mechanism, such as a dual rocker mechanism or other form of transmission, which is responsible for converting the motor's rotational motion into linear up and down motion of the tailgate.

(3) Safety function: Before the tailgate begins to move, the system uses sensors to check for obstacles. If any obstacles are detected or to prevent pinching, the operation will automatically stop or reverse to prevent damage or injury. And similar to the soft-closing doors of some luxury cars, electric tailgates usually include a soft-closing function that gently pulls the tailgate closed to avoid violent impacts and ensure safe closure.

(4) Intelligent function: In addition to the basic electric opening and closing function, some systems allow users to preset the height at which the tailgate opens, which is particularly useful for people with shorter stature or those with low garage ceilings. Some high-end configurations also allow users to set the tailgate opening height, memory function, intelligent anti-pinch, and linkage control through the vehicle's electronic system.

(5) Emergency override: In the event of a malfunction or electrical system failure, most systems include a manual override function that allows the user to manually open and close the tailgate.

2. Advantages:

(1) Convenience: For heavy loads or when the hands of passengers are occupied, the electric tailgate can be easily operated with one button, without the need to manually lift the heavy tailgate.

(2) Safety: Reduces the risk of injury that may result from manual operation, especially for drivers or passengers with less strength.

(3) Luxury: Increases the high-end and technological sense of the vehicle, and is commonly found in mid-to-high-end models or as an optional configuration.

3. Market Status

There are not only universal electric tailgate modification kits suitable for various models on the market, but also original accessories designed for specific models. With the advancement of technology and the reduction of costs, electric tailgate lifts are no longer exclusive to luxury cars. More and more mid-to-low-end models have begun to come standard or offer this option, meeting the needs of consumers for car convenience functions. Because it adds a touch of luxury and practicality to the vehicle. It not only enhances the user experience, but also contributes to the overall aesthetics and technological progress of the car.
