Cadillac SRX Vehicle Automatic Liftgate Control Opened and Closed by Easy Insatallation

What is the electric tailgate?

The smart electric tailgate is a brand-new car intelligent modification system. The driver can control the closing of the tailgate through the remote control of the car key, pressing the vehicle tailgate key and the cab. In addition, it also has functions such as intelligent anti-pinch, high-level memory, etc., which integrates intelligence, convenience and humanization, making your car even more powerful in an instant.

The intelligent electric tailgate can solve the inconvenience caused by the usual tedious trunk operation to daily life, such as not limited to being out of reach, too many things on hand, and not closing tightly.

The intelligent electric tailgate lift kit can open, close and lock the luggage electrically, which can be triggered by key fob, the switch button at the trunk, the switch in the cab, the foot sensor switch, etc. It has the characteristics of anti-pinch, self-adjusting height, speed control, abnormal fault detection, non-destructive installation and so on.

Using the original car standard electric suction device, the door opening and closing process is smoother and quieter. The kit runs smoothly, elegantly and intelligently, without extra noise.

Continue to understand the principle of the electric tailgate:

The basic structure of the electric tailgate is composed of two mandrel drive rods. The drive rod consists of an inner tube and an outer tube through the spindle drive. The motor and gear in the inner tube drive a threaded spindle.The threaded spindle moves on a threaded nut fixed to the inside of the outer tube. With regard to the use of the electric pillar, the motorized spindle of the motor inside the pillar compress and extend the spring in the tailgate, which also assists the opening / closing operation.

The Methods to open / close the tailgate:

Electric tailgate products should have the function of intelligent detection of obstacles and realize emergency braking. The tailgate can be stopped or moved in the opposite direction to prevent the motor from being burned out due to excessive current. And this function can avoid accidental pinching or damage the vehicle.

The principle of anti-clamp of the electric tailgate is that the hall sensor (ECU) inside the spindle motor detects the speed of the motor. When the tailgate touch an obstacles during the process of opening and closing, the speed of the motor will drops below the set limit. The sensor detects an obstacle and the motor current consumption increases, so the power supply is reversed, resulting in moving in the opposite direction of tailgate.

FAQ (After the installation of electric tailgate)

1. The control box does not work:

1) The location of taking power supply is wrong or not inserted.

2) The fuse is burned out. (In the fuse box on the electrical appliances).

3) The ground wire is not connected properly, resulting in poor circuit.

4) "Door Lock detection line" is not connected well.

5) Car battery is low.

6) Control box is damaged.

2. The tail gate is not closed in place:

1) The brackets are reversed or they are not installed as required.

2) The waterproof rubber strips and decorative panel of the rear trunk are nor installed properly, and the connecting wire of poles are not connect well.

3) The electric suction lock are not installed well. (Some car's base nuts can be moved. You need to push lock base forward and fix it.)

3. The poles are not work or run smoothly:

1) The connecting wire of poles are not connected well.

2) "Door Lock detection wire" are not connected well.

3) The ground wire of control box is not connected well or the power cable is not connected properly.

4) The poles or the control box are damaged.

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.
