Title:
MULTI-BAND ANTENNA DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/109549
Kind Code:
A1
Abstract:
Provided is a multi-band antenna drive device, comprising a driving gear (10), a divider (20) and lead screw assemblies (30). By rotating the divider (20), a boss (22) of the divider (20) pushes one of connection members (32), so that the connection member (32) is connected to a corresponding lead screw (31), and the power from the driving gear (10) is transmitted to the lead screw (31) through a driven gear (33) and the connection member (32) to rotate same, and at that moment, an elastic member (34) is in a compressed state, and the elastic member (34) can reliably transmit the power from the connection member (32) to the lead screw (31). The multi-band antenna drive device uses a circumferential layout, thereby saving a large amount of space and minimizing the overall volume. The divider (20) determines which lead screw assembly (30) needs to be adjusted, and the adjustment of multiple lead screw assemblies (30) is completed by one driving power, that is, one drives many. Another power source is an adjustment power for adjusting the divider (20). The rotation is transmitted jointly by means of the connection between the connecting member (32) and the lead screw (31) and the compressed elastic members (34), thereby making an adjustment action smoother and avoiding getting stuck.
