Nissan Terra Auto Power Tailgate Lift, Power Lift-Gate in Automotive Spare Parts Aftermarket

(Double Pole / Top / Bottom Suction Lock)

The power Hands-Free Smart Liftgate with Auto Open allows the driver to open the liftgate by simply standing within three feet of the rear bumper for more than three seconds with the key fob in a pocket or purse, which is especially helpful if raising and waving a foot under the bumper is impractical or impossible. The height-adjustment feature allows the driver to preset a stop for the liftgate to avoid low overhangs, such as in a garage.

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?

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?

1. The cost of single pole is lower. And if a car with a lighter rear door use single pole, all kinds of problems will be substantially reduced.

2. The conversion of single pole into double pole is not just increase a rod, it needs to be synchronized with software. For example, it needs to adjust the parameters so that the speed of two rods is consistent. In terms of product development, not only does the cost increase, but also it requires a lot of R&D energy and high-tech requirement. This is why many manufactures only produce single pole.
