Structure of electric glass lifter:
Because of its simple structure, convenient processing and low cost, arm glass lifter is widely used in vehicles in our country. Look, Laura and other models are using such structures lifter, so we focus on introducing.
Single arm glass lifter:
Single arm type glass lifts only a lift arm structure of the most simple, but because of the relative position between the lifting arm bearing point and glass centroid change frequently, lifting glass will produce tilt, stagnation, the structure is only suitable for glass on both sides of the parallel straight edge.
Double arm type glass lifter:
The structure of the double arm type glass lifter is characterized in that it has two lifting arms. The arrangement of the arms is divided into parallel arm type lifting device and cross arm type lifting device. Compared with the single arm type glass lifter, the double arm type glass lifter can ensure the parallel lifting of the glass, and the lifting force is relatively large. Among them, the cross arm type glass lifter has wider supporting width and relatively stable movement, and is widely adopted.
The parallel arm type glass lifter is relatively simple and compact in structure, but because the supporting width is relatively small and the working load is large, the stability of the stationary movement is less stable than that of the cross arm type glass lifter
Electric part of electric glass lifter:
When the streets of ignition switch, relay contact switch on the doors and windows closed door, electric circuit and power supply, combined switch or switch "on" position and switched on, current flows through the doors and windows motor, motor rotation drives the lifter, the glass doors and windows will rise; combination switch or switch "and" a current through the motor is switched on, the doors and windows the change of direction, thus changing the direction of rotation of the motor, elevator to drive down the glass doors and windows. When the door window rises or falls to the end, the disconnecting switch is cut off for a period of time before resuming to the connection state.
