Embodiment Construction
[0033] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0034] As shown in the figure, the spatially expandable loop antenna precisely synchronizes the gravity compensation system, including the truss, the main road stand, the motor drive system, the servo system and the suspension system;
[0035] The truss is composed of a plurality of truss unit structures, and the truss unit structure is composed of a synchronous hinge, a horizontal bar, a T-shaped hinge, a vertical bar and a telescopic bar. The T-shaped hinge connects the horizontal bar, the telescopic bar and the vertical bar. The synchronous hinge connects the horizontal bar and the vertical bar, and a cable is installed in the telescopic bar and the T-shaped hinge. When the cable shrinks, the cable drives the telescopic bar to shrink, thereby realizing the unfolding of the truss unit structure from the folded state;
[0036] The general road ...
