Abstract
The invention discloses a frame-variable support structure comprising a frame, variable supporting devices and a control system. The frame comprises posts and beams. The variable supporting devices comprise upper supporting rods, lower supporting rods and a drive. When the variable supporting devices are unfolded, one ends of the upper supporting rods are connected to the beams and the other ends are connected to the lower supporting rods, and one ends of the lower supporting rods are connected to the upper supporting rods and the other ends are connected to bottoms of the posts. The control system is a microcontroller with a program for driving rods to move. The microcontroller controls the drive through cables connected to the variable supporting devices and drives the variable supporting devices to move to determined positions. The frame-variable support structure has the advantages that normally the variable supporting devices are folded, the entire structure is a frame structure, and space capable of being used is large; when emergencies or accidents occur, the entire structure turns to a frame-supporting structure, and a house structure is allowed to have high shock resistance and impact resistance in short time.
