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 circuit can output graded early warning signals. The purpose of reflecting whether the protection plate is impacted and damaged or not through the on-off condition of the wires is achieved through the shearing effect of external force impact kinetic energy on the wires in the detection circuit layer, and after the multiple wires are impacted and broken, the detection circuit can output graded early warning signals.

    本申请提供一种防护板,包括上防护层、检测组件、下防护层,检测组件位于上防护层和下防护层之间;检测组件包括抗冲层、缓冲层和检测电路层,抗冲层、缓冲层和检测电路层在第一方向上层叠设置;检测电路层包括检测电路,检测电路包括若干检测导线,当防护板受到外力冲击且冲击能量从抗冲层传递至缓冲层时,高静压强度的缓冲层增大了抗冲层在受冲击处的应变程度,使得冲击形成的冲击坑可冲断检测电路中若干检测导线,在若干检测导线被冲断后,检测电路能输出分级预警信号。本申请利用外力冲击动能对检测电路层中导线的剪切作用,来实现通过导线通断的情况反映防护板是否受到冲击损伤的目的,且在若干导线被冲断后,检测电路可输出分级预警信号。
