Automobile glass lifter generally consists of the following parts: control mechanism (rocker arm or electric control system), transmission mechanism (gear, tooth plate or rack, gear shaft gear mechanism), glass lifter (lifting arm, bracket, bearing mechanism movement) glass (glass bracket) and a locking spring, balance spring. The basic working line of the glass lifter is the control mechanism, transmission mechanism, lifting mechanism and glass supporting mechanism. The balance spring to balance the gravity of the glass, in order to reduce the operating force; installed in the small gear and bearing between the retainer spring to hold the glass (stop), to ensure their stay in position.
Working principle
Electric glass lifter working principle: electric fork arm type glass lifter is composed of a common manual type glass lifter, reversible DC motor and reducer etc.. The working principle is to open the motor, the motor drives the reducer output power, through the active arm and the driven arm or pull rope moving glass mounting bracket, linear motion force for the rise or fall of the glass doors and windows.
Transmission line: swing handle - pinion - sector gear - lift arm (active arm or slave)
Movable arm -- glass mounting slot plate -- glass lifting movement.
function
(1) adjust the size of the door and window of the car; so the glass lifter is also called the door window adjuster, or the window swinging mechanism. (2) to ensure the smooth lifting of the door glass, doors and windows can be opened and closed at any time; (3) when the lifter does not work, the glass can stay at any position.
