Problems solved by technology
The antenna flip mechanism in the prior art is mainly driven by a motor, but since the radar antenna and the bracket are heavy, the distance between the center of gravity of the antenna and the bracket and the pitching shaft is relatively large, and the unbalanced moment generated when the antenna and the bracket are pitched is relatively large. Large, the use of motor drive will lead to excessive volume and weight of the entire drive system

The invention discloses a radar antenna turnover mechanism which comprises a bracket, a rotary table, a rotary arm, a connecting rod, a sector gear, a gear speed reduction system, a rotary shaft and a torsion bar balance mechanism. The bracket is used for installing a radar antenna, the bracket and the rotary table are connected through the rotating shaft, and the sector gear is connected to the bracket. One end of the torsion bar balance mechanism is fixed on the rotary table, and the other end of the torsion bar balance mechanism is connected with the rotary arm. And the rotating arm is connected with the bracket through the connecting rod. When the radar antenna and the bracket are overturned, the motor drives the gear reduction system to operate and drives the sector gear to operate, so that forward and reverse rotation of the radar antenna is realized. According to the radar antenna turnover mechanism provided by the invention, the torsion bar balance mechanism is utilized to balance the gravitational torque of the antenna and the bracket during pitching, so that the driving torque is greatly reduced, the size and weight of the whole driving system are further reduced, and the structural layout of the antenna turnover mechanism is also facilitated.
Description
technical field [0001] The invention relates to the technical field of radar equipment, in particular to a radar antenna turning mechanism. Background technique [0002] The current vehicle-mounted mobile radar, in order to meet the requirements of road and railway transportation, must strictly control the boundary shape of the radar in the transportation state. At the same time, in order to meet the requirements of rapid response of the radar, it is necessary to consider the turning time and maintainability of the turning mechanism. In addition, when the antenna is turned over to the outside of the working cabin, the turning mechanism is also used as a working platform for the antenna. The antenna flip mechanism in the prior art is mainly driven by a motor, but since the radar antenna and the bracket are heavy, the distance between the center of gravity of the antenna and the bracket and the pitching shaft is relatively large, and the unbalanced moment generated when the an...
