The lifting (closing and opening) of the door window glass has abandoned the manual lifting mode of shaking handle, and generally the push-button electric lifting mode is adopted, that is,
the electric glass elevator is used.
The electric glass lifter is mostly composed of motor, reducer, guide rope, guide plate, glass mounting bracket, etc. Due to the different materials or production methods of guide rope,
it can be divided into rope wheel type, flexible shaft type and plastic belt type. The first two use steel wire rope as a guide, and the second uses plastic tape as a guide.
Take the rope wheel electric glass elevator as an example. It is composed of motor, reducer, wire rope, guide plate, glass mounting bracket and other parts. During installation,
the window and door glass is fixed on the glass mounting bracket, and the glass guide slot is parallel to the wire rope guide plate. Start the motor,
the motor drives the reducer to output power, pull the wire rope to move the glass mounting bracket, and force the Windows and doors glass to move up or down in a straight line.
The guide rope of the plastic belt type electric glass lifter is a plastic belt with holes, which is used to move and position the plastic belt and control the rise and fall of the window glass.
Electric glass riser structure is the key to the motor and reducer, the two are assembled into a whole, including motor USES the reversible permanent-magnet dc motor, motor,
two groups around to different field coil, can be done by controlling the switch forward and inversion, that is, the rise or fall can control door and window glass.
The motor is controlled by a double switch button, with three working states, such as up, down and off. When the switch is not operated, it stops at the "off" position automatically.
The control circuit is provided with master switch (central control) and separate switch, and the two lines are connected in parallel. The main switch is controlled by the driver,
and the opening and closing of all Windows and Windows glass, and the separate closing of the handle inside each door is controlled by the occupant, so the operation is very convenient.
