CONTROL DEVICE FOR ADJUSTING ELECTRIC DOWN-TILT ANGLES OF MOBILE COMMUNICATION ANTENNA

摘要

A control device for adjusting electric down-tilt angles of mobile communication antenna includes: a case; and a control module, a motor, a driving mechanism, and a driving axis that are arranged in the case. The driving axis extends out the case and fits with the manipulator of the adjusting device of the antenna phase shifter. The driving mechanism comprises a planet gear mechanism and a force moment restricting mechanism. The rotating shaft of the motor is connected to the planet gear and directly or indirectly connected to the driving axis. The control module is electrically connected to the motor, so as to realize controlling the motor. The control device has great versatility, and need not change the inner structure of the control device for different mechanism travel of the antenna phase adjusting shifter, thus is of great benefit to form a uniform standard.
