[technical field]
This utility model relates to antenna of mobile communication base station field, drives more particularly, to a kind of electrical tilt antenna
Motivation structure.
[background technology]
Society science and technology is advanced by leaps and bounds, and electronics and IT products make rapid progress, more and more higher to antenna requirement.
Traditional fixed antenna can not meet the demand of people, and be born a kind of novel electrical tilt antenna.Its energy
The electrical tilt angle of enough physical location long-range control break antenna phasing units according to antenna, thus change signal
Overlay area, it is ensured that signal reliable and stable.Present machinery is evolved in purely mechanic control before from
Electrically control together.The drive mechanism that the mechanical electric of present stage controls together, uses screw-driven (class mostly
Mode seemingly) is converted to the linear mobile of antenna phasing unit the rotary motion of motor.Pass through electrical control
The rotation of motor (motor), it is achieved the change at antenna phasing unit inclination angle, but when antenna phasing unit arrives
During maximum or minimum angle, it is necessary to have one to feed back signal to motor (motor), allow motor (motor) stop
Rotate (or reversion).In reality application, mostly use and be rigidly connected, directly limit nut and no longer move
Ensureing the safety of phase shifter, screw rod enlarging moment of leaving is rotated further, during until exceeding the output torque of motor
Motor just stops, and is the most not only easy to destroy screw thread, is difficult to realize motor reversal, of long duration, also holds
Easy burn-out motor；After thread damage, the inclination angle of phase shifter cannot be regulated again, to the personnel of installation and debugging
Make troubles, decrease antenna service life.
Generally connected by a connecting rod between the antenna phasing unit and the drive mechanism that use on the market at present, even
Different in nature hole and the different in nature axle of drive mechanism on bar coincide, it is impossible to the linear of Complete Bind connecting rod is moved, and is difficult to
Accurately control the inclination angle precision of phase shifter, make troubles to construction commissioning staff.
Actual application is typically on the support installing antenna, paste a scale, fixing on the bottom end cover of antenna
One mark post, shows phase shifter electrical tilt angle by mark post and scale, due to the location comparison of exterior aerial
Special, scale is difficult to debugged personnel and sees, and basis reference is the most uncertain, time length of exposing to the weather,
Scale is unclear is difficult to identification；Increasingly mature along with antenna technology, it is increasingly exquisiter tight that antenna product is done
Gather, the mark post exposed, and cable connector is close, connecing cable to workmen makes troubles.
To this end, need badly a kind of debug simplicity, the drive mechanism of electrical tilt antenna that accuracy is high.
