Automobile glass lifter is door door glass lifting movement of the door system, is a special component regulating glass of door opening size, its function is to ensure the smooth lifting of the door window glass, and the smooth opening and closing.
When the external control of the lifter is withdrawn, the glass should stop at any position, neither can it glide automatically nor can it jump up and down due to the jolt of the car. The glass bracket is driven by the glass lifter to move up and down, so that the door glass moves up and down along the guide groove or the guide rail of the window frame of the door.
With the rapid development of China's automobile industry, the output of automobiles will be greatly increased, and the demand for electric lifts will be greatly increased. It is becoming a standard auto accessory.
The glass lifter breaks up the movable glass lifter, the electric glass lifter, the hydraulic glass lifter and so on according to the operation mode. The composition of the electric glass lifter is equivalent to the assembly of the three parts of the same type manual glass lifter, the motor and the reducer. Compared with the traditional hand lift, the electric glass lifter has the advantages of smooth operation, convenient adjustment and remote control.
The electric glass lifter can be divided into two parts according to its mechanical lifting mechanism.
Rope wheel: the motor drives the winding wire to rotate, drives the wire rope and pulls the glass bracket up and down in the guide rail. The lifter has the advantages of less parts, light weight, simple structure and adjustable installation position. The disadvantage is that the position of the wire rope guide plate must be adjusted so as to be parallel to the glass guiding slot on the window. Otherwise, when glass is moving, it is easy to produce glass and guide slot stuck phenomenon. Mainly used in cars, other cars rarely used.
The flexible shaft type: the motor drives the small gear to rotate, and drives the flexible shaft to slide in the shaft sleeve, so that the glass bracket moves on the guide rail, and the purpose of the glass lifting is completed. The lifter has the advantages of less parts, simple structure, stable operation, no noise, and adjustable installation position. The disadvantage is that the flexible shaft is composed of a plurality of steel wire ropes and spiral shells, and the upper part of the steel wire rope is covered with fluff. The manufacturing process is more complex. Widely used, all kinds of cars can be used.
Cross arm type: the motor drives the small gear to drive the sector tooth plate to rotate, and the glass bracket moves up and down through the lever of the cross arm, so that the glass moves up and down in the guide rail. The advantages of this lift is of high strength, easy processing, because the glass is supported by two cross arm end, in the process of movement, the support center is always close to the glass centroid, the support width is larger, so the lift is relatively stable, by using general. The structure can be used for glass lifting on the door window frame with non parallel glass guide. The disadvantage is that it is heavier than other types of electric glass lifter.
