Nowadays various cutting-edge automation functions are brought into vehicle

domains, and modifying the traditional tailgate into an intelligent one has

become a preferred option of car tuning for many car owners. The electric

tailgate helps deal with the problem of SUV or large vehicle's tailgate being

too high to close. It also allows car owners to open and close the tailgate easily

when they get their hands full with groceries. The electric tailgate is also

equipped with intelligent anti-pinch system to avoid accidental injuries and

memory function to accommodate users of different heights.

As knowing how convenient a smart tailgate can be, now a question may come

to your mind: so, how does an intelligent tailgate work?

To put it simply, the basic structure of the spindle drive of electric tailgate's

pushing rod consists of an inner tube and an outer tube. The DC motor and

the gearbox in the inner tube together drive the electric spindle, actuate the

compression or elongation of the springs, and thus actuate the pushing rods to

open or close the tailgate. 

Besides, by installing hydraulic brackets and engine control unit (ECU), car

owners can effortlessly open or close the tailgates by using key fobs, pressing

the tailgate switches, or making use of intelligent detection to sense their

hands or any objects within the tailgate sensing area.
