Detailed explanation of electric tailgate:
I. Overview:
Intelligent electric tailgate. The driver and passenger can control the opening and closing of the tailgate by pressing the opening key of the tailgate, remotely controlling the key of the tailgate, or using hands or any objects in the corresponding area of the tailgate. The electric tailgate also has the functions of intelligent anti-pinch and high memory. It has the advantages of convenient control and strong practicability, so it is widely used in C-class luxury cars and B-class vehicles, such as Land Rover Aurora, Range Rover Series, Ford Maverick, Volvo XC70 and so on.
The refitting of non-standard electric tailgate has increasingly become the focus of refitting market. By adding hydraulic supports, sensors (ECU) and other components to the original tailgate, the bulky tailgate that is manually opened becomes a "good assistant" that is arbitrary, convenient and practical. At present, the domestic electric tailgate refitting market is still in its infancy. The main tailgate refitting brands are "winbo Ruibo" and "Yupin" electric tailgate series and other small factories.
Second, the main accessories:
1. Electric prop
2. Electric tensioning motor
3. Crash bolt and bolt assembly
4. Trunk lid module
5. Electric prop
Third, the product structure:
The basic structure of electric tailgate is composed of two spindle driving rods. The driving rod consists of an inner tube and an outer tube through a spindle driver, wherein a motor and a gear in the inner tube drive a threaded spindle which moves on a threaded nut fixed on the inner side of the outer tube. The electric prop uses the electric spindle located in the motor inside the prop to open and close the trunk lid spring, which also helps the lid opening operation.
Third, the opening mode
1. The tailgate of the vehicle is opened and closed. The tailgate opening and closing operation is realized by pressing the tailgate opening key on the instrument panel or tailgate of the vehicle. See the figure below, 1 is the key for tailgate opening; 2 open the key for the tailgate of the instrument panel.
2. The electronic car key is remotely opened and closed. The tailgate is opened and closed through the unlocking and locking key on the electronic car key.
3, inductive opening and closing. When a hand or any object is placed in the corresponding sensing area of the tailgate, it can automatically open the tailgate. It is suitable for the situation that it is not convenient to manually use or use the electronic car key because there are too many objects on hand. In 2013, Ford Maverick adopted this technology on its high-end models.
Fourth, security:
1. For drivers and passengers.
Qualified electric tailgate products should have the function of intelligently detecting obstacles and realizing emergency braking. When the tailgate is opened, it can automatically retract when encountering obstacles to avoid burning the motor due to excessive current. When it is closed, it can bounce back automatically when it encounters obstacles, so as to avoid accidental pinching or damage to the vehicle.
The principle of electric tailgate anti-pinch is that the Hall sensor (ECU) inside the spindle motor will monitor the speed of the motor. When the tailgate encounters an obstacle when it is opened or closed, and the motor speed drops below the set limit, the sensor detects the existence of the obstacle, and at the same time, the power supply of the motor will be reversed when the motor current consumption increases, resulting in the trunk lid moving in the opposite travel direction.

2, for the original car modification.
The modification of electric tailgate belongs to the modification of automobile electronics, and safety is the primary consideration in the modification of automobile electronics products. Qualified modified electric tailgate products should try to avoid changing the computer and circuit of the original car, damaging the car body and preventing short circuit caused by changing the computer and circuit of the original car. “
V. Main functions:
1, the hand from one open
The driver and passenger can open and close the tailgate by pressing the vehicle tailgate opening key, remotely controlling the vehicle key, or using hands or any object induction operation in the corresponding area of the tailgate, so as to avoid the inconvenience of opening the door due to holding too many objects, and easily and quickly realize the storage of objects in the vehicle.
2. Intelligent anti-pinch function
When the tailgate is closed, the sensor detects obstacles. When the electric tailgate meets obstacles during opening or closing, the door will move in the opposite direction, effectively preventing children from being pinched or vehicles from being damaged.
3, emergency locking function
When the tailgate needs to be closed in an emergency, the tailgate can be stopped at any time by remote control key or vehicle tailgate opening key during the opening or closing of the electric tailgate, and the control can be arbitrary.
4. High memory function
The opening height of the tailgate can be adjusted, and the owner can set the final opening height of the tailgate through the manual button according to the usage habit. Just press the tailgate opening key to open it to a predetermined height, and then press the opening key lightly for more than 5 seconds, and then the setting of the tailgate opening height can be completed when a beep is heard. When the tailgate is opened next time, the height will automatically rise to the set height.
VI. Matters needing attention
1. Before opening the electric tailgate, be sure to pay attention to the fact that there are no sundries, ceilings, back walls, etc. within the opening range of the tailgate, so as to prevent the tailgate from being scratched due to opening the tailgate without paying attention to obstacles;
2. When the electric tailgate is completely closed, it will give a "beep" alarm sound. Do not start the vehicle before you hear the closing alarm to prevent accidents due to the unclosed tailgate.
