Do you know why the electric tailgate can be anti-clamped?

Let us tell you why.

Electric tailgate anti-clamp principle:

The principle of anti-clamping is that the ECU monitor the speed of the motor. When the tailgate encounters obstacles, the motor speed drops below the set limit. At the same time, the motor current consumption increases and the power supply to the motor is reversed, so that the trunk will move in the opposite direction. The basic structure of the electric tailgate is two mandrel drive rods. The driving rod is composed of an inner tube and an outer tube. The motor and gear in the inner tube drive a threaded spindle. The thread spindle moves on the screw nut which fixed to the inside of the outer tube. With regard to the operation of the electric prop, the electric spindle inside the prop drives the operation of the trunk spring. Qualified electric tailgate products should have the function of intelligent detection of obstacles and emergency braking. When the tailgate encounters an obstacle, it can be automatically retracted to prevent the motor from being burned out and avoid accidental pinching or damage to the vehicle.

Double Pole (Rod) / Singe Pole (Rod), What are they different?

Single Pole (Rod): The single pole is the originator of the electric tailgate and it is the first generation electric tailgate. The electric pole replaces one of the tailgate hydraulic rod to identify the car computer signal. Finally, pressing the original car fob or the tailgate opening button to open/close the tailgate. But what are the advantages and disadvantages of single pole?

• Advantages: Car owners can buy it at a lower price, because it only need one rod to work and the cost is cheaper.

• Disadvantages: The single pole has only one support rod. The tailgate is opened by the electric motor in the support rod. However, there are some hidden dangers and deficiencies for SUVs

The rear doors of SUV are usually very heavy and some are more than 100 kilograms. Just one support rod is not strong enough to support, resulting in inhomogeneous force. Utility time will not exceed 2 months. Not only will the tailgate be deformed, but also hinge failure. It will have a great influence on the safety of the car owner.

Double Pole (Rod): The double pole is developed on the basis of the single pole. Using double pole, it will not occur some problems as above mentioned.

At this time, many people will ask why manufactures do not all produce double pole? Why not all use double pole?
