A vision protection device based on cloud platform electronic school bag

Abstract

The invention relates to the technical field of cloud platforms. The invention further discloses an eyesight protection device based on a cloud platform electronic schoolbag. The eyesight protection device includes a machine body, wherein a rectangular block is fixedly connected to the right side of the machine body; a mechanical bin is formed in the upper portion of the rectangular block; a timing cylinder is fixedly installed on the lower left portion of an inner cavity of the mechanical bin; a piston is arranged in an inner cavity of the timing cylinder; connecting rods extending to the upper portion of the timing cylinder are fixedly connected to the left side and the right side of the upper end of the piston; second springs are movably connected to the connecting rods in a sleeving mode; and first magnet blocks are fixedly installed above the connecting rods. The eyesight protection device based on a cloud platform electronic schoolbag enables the first magnet block and the secondmagnet block to repel with each other by twisting the torsion bar, so that the first magnet block firstly leaves the pressure sensing layer and then returns to be in contact with the pressure sensinglayer, and the rotating frame is matched with the signal bead for contact early warning, so that the effects of forcibly controlling time to protect eyesight, giving early warning in advance and adjusting eye using time according to needs are achieved.
