Abstract: The present invention relates to a transmission unit for a phase shifter of a base station antenna. The transmission unit includes a gear set, a driving connecting rod configured to be coupled with a drive unit, a controlling connecting rod configured to control the phase shifter, and a scale connecting rod configured to be mounted with a scale, wherein the driving connecting rod, the controlling connecting rod, and the scale connecting rod are respectively meshed with the gear set, and the controlling connecting rod is in transmission connection with the scale connecting rod through the gear set with a first transmission ratio less than 1. In this way, the display of the electrical downtilt angle of the phase shifter by use of the scale can be improved by simple measures.

Abstract: The present invention relates to a transmission device for a phase shifter and an actuator device for a phase shifter. The transmission device includes a support, a lead screw nut mechanism and an automatic locking device. The automatic locking device includes a shaft connector rotatably supported on the support and configured to be in transmission connection with a driven connector of a driving device; a locking connector which is in transmission connection with the shaft connector, is in transmission connection with the lead screw, has a locking element and is movable relative to the shaft connector and the lead screw; and a locking spring. When the driven connector is decoupled to the shaft connector, the locking spring biases the locking connector in a first position, in which the locking element engages a counter-locking element on the support. When the driven connector is decoupled to the shaft connector, the locking connector is moved by the driven connector to a second position, in which the locking element disengages the counter-locking element on the support. Calibration of the phase shifter may be saved when the driving device is replaced or repaired.
