Phase shifter transmission device

Abstract

The invention discloses a phase shifter transmission device which comprises a pull rod component. The pull rod component comprises a pull rod, a supporting frame and at least two first transmission assemblies. The supporting frame is provided with an upper supporting layer and a lower supporting layer. Each supporting layer is provided with at least one first transmission assembly. The first transmission assembly comprises a first screw, a first nut which sleeves the first screw and can perform linear reciprocation in a length direction, and a first gear which is rigidly connected with one end of the first screw and has a rotation direction that is same with that of the first screw. The pull rod is detachably connected with the first nut. The first gear is driven by an external transmission force for driving the first screw to rotate so that the first nut drives the pull rod to move in the length direction of the first screw, and furthermore displacement of the phase shifter which is connected with the pull rod can be adjusted. Through the technical solution of the invention, the phase shifter provided by the invention realizes advantages of settling a problem of large area occupation by the phase shifter in flat placement, reducing mounting volume of the phase shifter transmission device and improving transmission precision.

Description

technical field [0001] The invention relates to the technical field, in particular to a phase shifter transmission device. Background technique [0002] At present, the antenna transmission of ESC base stations in domestic and foreign markets mainly adopts one-to-one transmission mode, that is, one motor controls one phase shifter. With the development of communication, multi-frequency antennas have become the mainstream trend. The phase shifter will also increase accordingly, and the width of the antenna will also increase. The scheme of driving a phase shifter by one transmission is obviously not suitable for the development of multi-frequency antennas. The integrated development of the transmission solves the problems of large space occupation and high cost, but With the increase of the antenna width, there is a problem of transfer. The large transfer distance leads to a series of defects such as large friction force of the tie rod, large deformation of the transfer plate...

[0002] At present, the antenna transmission of ESC base stations in domestic and foreign markets mainly adopts one-to-one transmission mode, that is, one motor controls one phase shifter. With the development of communication, multi-frequency antennas have become the mainstream trend. The phase shifter will also increase accordingly, and the width of the antenna will also increase. The scheme of driving a phase shifter by one transmission is obviously not suitable for the development of multi-frequency antennas. The integrated development of the transmission solves the problems of large space occupation and high cost, but With the increase of the antenna width, there are transfer problems. The large transfer distance leads to a series of defects such as large friction force of the tie rod, large deformation of the transfer plate, and even jamming.

[0003] The technical problem solved by the present invention is to provide a detachable modular two-drive multi-rod transmission device, which aims to solve the problems of wide arrangement of multi-frequency antenna phase shifters, long horizontal transfer distance, poor precision, friction, etc.
