Problems solved by technology

When it is necessary to set up a multi-frequency antenna, the transmission mode of the multi-frequency antenna is a simple superposition of a single-frequency antenna, that is, one motor alone controls one phase shifter. For a multi-frequency antenna, it is necessary to realize the separate adjustment of multiple phase shifters It is necessary to configure multiple motors. Due to the high price and heavy weight of the motor, it not only leads to a large antenna size, but also increases the cost. There are disadvantages such as complex structure, difficult production, and high cost.

Abstract

The invention discloses an antenna phase shifter transmission device. The antenna phase shifter transmission device comprises a lower mounting frame, a position selection component, a driving gear, aplurality of driven gear sets, an input shaft and a plurality of output shafts; the position selection component comprises a position selection disc, a first planetary gear set, a second planetary gear and a planetary gear support frame; each output shaft is provided with an output gear which can synchronously rotate with the output shaft; the driven gear sets are meshed with the driving gear; theposition selection disc is rotated to enable the first planetary gear set and the second planetary gear of the position selection component to be respectively and sequentially meshed with the outputgear on each output shaft; the first planetary gear set drives the output gear to rotate in the direction opposite to the direction in which the second planetary gear set drives the output gear to rotate. The antenna phase shifter transmission device is compact in structure, light in weight and high in reliability, the number of motors can be saved, and the antenna cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of mobile communication antennas, in particular to an antenna phase shifter transmission device. Background technique [0002] The radiation angle of the mobile communication antenna needs to be adjusted according to the change of the main source of the antenna, and the method is to adjust the phase shifter in the antenna by driving the transmission device. [0003] In traditional phase shifter transmissions, most of the phase shifter transmissions are one-to-one, one motor controls one phase shifter independently, different phase shifters are controlled by corresponding drive motors, and the rotation of each motor The torque is converted into linear motion by a set of transmission structural parts. When it is necessary to set up a multi-frequency antenna, the transmission mode of the multi-frequency antenna is a simple superposition of a single-frequency antenna, that is, one motor alone controls one phase...
