Abstract
The invention relates to a compass school bag, including straps. A strap buckle is disposed on the straps. A compass signal module is disposed on the strap buckle. The compass signal module comprises an elastic substrate. The central portion of the elastic substrate is fixed with a compass positioning module equipped with a compass chip. The compass signal module also comprises a signal antenna. The signal antenna consists of two sets of L-shaped centrosymmetric conductive sheets. The conductive sheets include two L-shaped pins, and each pin is integrally provided vertically with an auxiliary pin. The auxiliary pin and the other pin are perpendicular to each other on the plane of the conductive sheet. One of the auxiliary pins of the signal antenna is connected with a signal output end of the compass positioning chip through a flexible printed circuit. Fixing grooves are disposed in the elastic substrate and corresponding to positions between the pins and the auxiliary pins. The straps on two sides of a dial plate respectively penetrate through the fixing grooves at two sides of the compass chip.
