Antenna bracket with adjusting function

摘要

An antenna bracket includes two substrates having a bottom surface and a supporting surface; a plurality of movable rollers installed on the bottom; two columns, respectively set up on the supporting surface of the substrates; a beam with two ends movably connected with the two columns; two first driving members, fixed on each supporting surface and connected with the beam to drive the beam to slide upward and downward relative to the two columns; an antenna base, movably connected with the beam to install an antenna; a second driving member, fixed on the beam and connected with the antenna base, to drive the antenna base to slide horizontally; two first electromagnetic shield covers and a second electromagnetic shield cover respectively covering the two first driving members and the one second driving member, to attenuate electromagnetic interference (EMI) emanation from openings in the first driving members and the second driving member.

主权项

1. An antenna bracket comprising:
two substrates each of which has a bottom surface and a supporting surface opposite to the bottom surface; a plurality of movable rollers, installed on the bottom surface of the substrates, to move the antenna bracket; two columns, respectively set up on the supporting surface of the substrates; a beam with two ends movably connected with the two columns; two first driving members, respectively fixed on each supporting surface and connected with the beam to drive the beam to slide upward and downward relative to the two columns; an antenna base, movably connected with the beam to install an antenna; a second driving member, fixed on the beam and connected with the antenna base, to drive the antenna base to slide horizontally; two first electromagnetic shield covers, respectively fixed on each supporting surface and covering the first driving member, to attenuate electromagnetic interference (EMI) emanation from openings in the first driving member; and a second electromagnetic shield cover, fixed on the beam and covering in the second driving member, to attenuate EMI emanation from openings in the second driving member.
