Abstract

The invention discloses a transmission device capable of selecting an output shaft. When the input shaft rotates in a first rotation direction, the input shaft drives a rotating frame to rotate through a transmission assembly and a one-way transmission assembly until a transition gear can be connected with any group of output shafts. When the input shaft rotates in the second rotation direction opposite to the first rotation direction and the rotating frame is at the predetermined position, the input shaft is driven by gear A, transition gear and gear B The corresponding output shaft rotates and outputs; that is to say, through the input shaft along the first rotation direction, the transition gear is driven to rotate to mesh with the gear B on the selected output shaft; through the input shaft along the second rotation direction, the input shaft passes through the gear A. , The meshing between the transition gear and the gear B can drive the output shaft to rotate, that is, only one motor is needed to drive different output shafts to rotate independently.

Description

technical field [0001] The invention relates to a transmission device that can select an output shaft, and also relates to an antenna device. Background technique [0002] In the mobile communication technology, the radiation angle of the base station antenna needs to be adjusted to cover different mobile communication areas, and the antenna is usually adjusted by using an antenna transmission mechanism. The antenna adjustment drive mechanism has a significant impact on the cost, weight and size of the antenna. At present, most of the base station antennas on the market are a set of motors (including a servo motor and a corresponding driver) to drive an antenna to act alone. To realize the independent adjustment of multiple antennas, it is necessary to configure motors equal to the number of antennas. Due to the high price of motors , resulting in a bulky and expensive antenna. [0003] The present invention is researched and proposed for the deficiencies of the prior art....
