Embodiment Construction

[0027] Such as figure 1 and figure 2 As shown, a large working space variable drive parallel antenna seat mechanism is provided, including a fixed platform 1 and a moving platform 2 arranged in parallel. The fixed platform 1 and the moving platform 2 have the same structure, and the fixed platform is a triangular plate or The fixed platform is a hexagonal plate, the moving platform is located above the fixed platform, and the fixed platform and the moving platform are connected by three moving branch chains evenly distributed along the circumferential direction, and the distance between the moving branch chains is 120 ° Evenly distributed.

[0028] Such as figure 1 As shown, each motion branch chain includes a swing rod 3 and a linear drive unit 4, one end of the swing rod and one end of the linear drive unit are hinged through a spherical pair 5, and the other end of the linear drive unit is the driving end. The driving end of the linear drive unit is hinged to the side w...

Abstract

The invention discloses a large working space variable driving parallel antenna seat mechanism and belongs to the field of an antenna device. The antenna seat mechanism comprises a fixed platform, a moving platform and three motion branch chains having identical structures, wherein the motion branch chains comprise swing rods and linear driving units, the motion branch chains are respectively connected with the fixed platform and the moving platform through revolute pairs, and the revolute pairs connected with the fixed platform and the moving platform are respectively uniformly distributed along respective circumferences with an angle interval of 120 DEG. The antenna seat mechanism is a parallel mechanism, continuous tracking of the antenna for an any-attitude non-blind target area in a work scope can be realized, slip ring and joint equipment can be saved, a driving mode is variable and can adapt to large work space scope antenna demands, and the antenna seat mechanism further has properties of symmetric structure, compact structure, large rigidity, high directional precision, strong bearing capability and good dynamic characteristic.

Description

technical field [0001] The invention belongs to the field of antenna devices, and relates to a large working space variable drive parallel antenna seat mechanism, which is applied to fixed, vehicle-mounted, airborne and ship-borne satellite receiving antennas in aerospace remote sensing and satellite communications. Background technique [0002] The satellite antenna is generally composed of an antenna reflector connected with an antenna base. The antenna base is the support and orientation device of the antenna, which is used to enable the antenna to move according to the predetermined trajectory or follow the target. Its structure greatly affects the overall performance of the antenna. Performance. [0003] At present, there is a "blind cone" area in the zenith position of the classic pitch-azimuth antenna used in the world's known aerospace remote sensing, which cannot be continuously tracked "over the top". The size of the blind cone area (ie, the cone of the blind cone ...
