Theory
• Electric Servo Control:The working principle of the electric
strut is based on electric servo control,which involves single-chip
control modules that manage functions such as switch control,remote
control,anti-pinch,light control induction,and smooth operation.
• Balance Spring:Inside the strut,there is a balance spring that
serves to balance the weight of the tailgate.
• Motor Operation:The motor controls the rotation of the screw
rod,converting the rotating force into longitudinal expansion and
contraction,which enables the tailgate to open and close.
• Control Module(ECU):The electric struts are connected to a
control module or an electronic control unit(ECU)that manages the
operation of the tailgate.This module serves as the brain of the
system,interpreting signals and controlling the electric struts
accordingly.
• Control Mechanism:The control mechanism allows the user to
initiate the opening or closing of the tailgate through various
means,including remote control,vehicle key fob,buttons or
switches,and optional foot sensors for hands-free operation.
• Position Feedback:The control module often receives feedback from
position sensors on the struts,indicating the current position of
the tailgate.This feedback is crucial for ensuring precise control
and safety during the opening and closing processes.
• Adjustable Parameters:Some electric tailgate systems allow users
to adjust parameters such as the opening height or speed of the
tailgate,which can be done through the control module or a
dedicated app.
• Safety Features:Electric tailgate struts are designed with safety
features to prevent accidents or injuries,including obstacle
detection and anti-pinch functions.
• Strut Module:The electric strut module is composed of components
like the ball joint,Hall sensor,drive motor,gear box,screw,nut,and
booster spring.The drive motor receives instructions from the
controller module to rotate forward and backward,and through the
gear box,it drives the screw and nut to rotate relative to each
other,pushing the electric strut to axially extend or contract.
• Suction Lock Module:The electric pull-in lock module is composed
of the tail door lock assembly,the lock assembly,the pull-in
motor,and the winding wire.This allows the tailgate to be
electrically closed from the half-locked state to the fully-locked
state by the pull-in motor.
• Anti-Pinch Function:The electric strut module has a built-in Hall
sensor with Hall anti-pinch function.If an obstacle is detected
during the closing of the tailgate,the internal conductor contacts
and conducts,and the controller module(ECU)receives the signal to
control the electric strut to reverse and open the tail door.
