Zusammenfassung: | The invention provides a protection plate which comprises an upper protection layer, a detection assembly and a lower protection layer, and the detection assembly is located between the upper protection layer and the lower protection layer. The detection assembly comprises an anti-impact layer, a buffer layer and a detection circuit layer, and the anti-impact layer, the buffer layer and the detection circuit layer are stacked in the first direction; the detection circuit layer comprises a detection circuit, the detection circuit comprises a plurality of detection wires, and when the protection plate is impacted by external force and impact energy is transmitted from the anti-impact layer to the buffer layer, the buffer layer with high static pressure strength increases the strain degree of the anti-impact layer at the impacted part, so that the plurality of detection wires in the detection circuit can be broken by impact pits formed by impact; after the plurality of detection wires are broken, the detection c |
