There are three ways to achieve an electric tailgate in the trunk of a car: a motor driven strut, a rocker arm strut, and a hydraulic strut.

Motor drive: Easy to implement, but with high production process requirements;

Rocker arm type: low cost, but occupying space;

Hydraulic: The advantage is quietness, but it takes up space;

After installation is completed, test whether it is qualified. The main criteria for distinguishing good and bad products of the electric tailgate are as follows:

1. Whether the anti pinch force is gentle and gentle, supported by one hand with a force not exceeding eight kilograms, and if the anti pinch force is large, it is unqualified;

2. Whether the high point of opening the car door will automatically fall, and if there is a fall, it is unqualified;

3. Whether the door is slammed forcefully at the moment of closing the door, and whether the injured car lock is not qualified after being slammed forcefully;

4. Is the noise loud? External noise is a sign of internal nonconformity;

5. Whether the left and right gaps are even after installation, and if they are uneven, they are unqualified;

6. Does the door open and close at a constant speed throughout the entire journey? The opening and closing time is 6 seconds plus or minus 1 second, and if it is too fast or too slow, it is not qualified;

7. If there is no electrified suction structure, or if the electric suction effect of the car door is not obvious, it is also unqualified!
