Title:
TRANSMISSION MECHANISM AND ANTENNA
Document Type and Number:
WIPO Patent Application WO/2023/077690
Kind Code:
A1
Abstract:
A transmission mechanism and an antenna comprising same. The transmission mechanism comprises a drive shaft (1) and a stop assembly (4). The stop assembly (4) comprises: a base (41), a first thread (412) being formed on a surface of the base (41); and a rotating component (42), the rotating component (42) being disposed on the drive shaft (1) and capable of rotating along with the drive shaft (1), and a second thread (421) matched with the first thread (412) being formed on a surface of the rotating component (42), wherein at least one of the base (41) and the rotating component (42) is provided with a stop portion. When the drive shaft (1) rotates, the rotating component (42) rotates along with the drive shaft (1) and forms relative sliding with the base (41) by means of the engagement between the first thread (412) and the second thread (421); and when the stop portion abuts against the base (41) or the rotating component (42), the relative sliding between the base (41) and the rotating component (42) is stopped. The stop assembly uses fewer parts, and structural fit clearances are correspondingly reduced, such that the initial phase shift position of a phase shifter can be calibrated more accurately, thereby improving the accuracy of phase adjustment.
