Foldable satellite dish

A foldable satellite dish, comprising a dish reflector assembly, a support housing, and a driving mechanism;

• wherein,
• the support housing comprises a bottom plate;
• a first vertical plate extends upward from a first edge of the bottom plate;
• a first barrier panel extends from the first vertical plate;
• a second vertical plate opposing the first vertical plate extends upward from a second edge of the bottom plate;
• a second barrier panel extends from the second vertical plate;
• the first barrier panel is perpendicular to the second barrier panel;
• a third vertical plate extends upward from a third edge of the bottom plate;
• a central through-hole is provided on the third vertical plate;
• a first screw rod through-hole is provided on the third vertical plate;
• the driving mechanism comprises a main shaft, a dam-board, a first screw rod, a main driving motor, and a screw rod driving motor;
• a first main shaft end is rotatably mounted in the central through-hole and driven by the main driving motor;
• a second main shaft end is provided with a first external spline tooth;
• a second spring pin, a third spring pin, and a fourth spring pin are provided sequentially on the main shaft near the first external spline tooth;
• the dam-board is provided with a main shaft hole and a first threaded hole;
• one end of the first screw rod is rotatably mounted in the first screw rod through-hole and driven by the screw rod driving motor;
• another end of the first screw rod is threaded into the first threaded hole;
• the main shaft is rotatable through the main shaft hole;
• the first screw rod drives the dam-board slides along the main shaft;
• and
• the dish reflector assembly comprises a central disc, a first quarter circle shape dish sector with a first ring that matches diameter of the main shaft, a second quarter circle shape dish sector with a second ring that matches diameter of the main shaft, a third quarter circle shape dish sector with a third ring that matches diameter of the main shaft, and a fourth quarter circle shape dish sector with a fourth ring that matches diameter of the main shaft;
• the central disc is fixed at the second main shaft end;
• the first ring has an internal spline tooth coupled to the first external spline tooth;
• the second ring has a second pin hole corresponding the second spring pin;
• the third ring has a third pin hole corresponding the third spring pin;
• the fourth ring has a fourth pin hole corresponding the fourth spring pin;
• wherein, the foldable satellite dish has a folded state and a deployed state;
• in the folded state, the first quarter circle shape dish sector, the second quarter circle shape dish sector, the third quarter circle shape dish sector, and the fourth quarter circle shape dish sector are sequentially arranged along the main shaft between the first barrier panel and the second barrier panel;
• in the deployed state, the second ring is secured to the main shaft by the second spring pin, the third ring is secured to the main shaft by the third spring pin, the fourth ring is secured to the main shaft by the fourth spring pin.
