The invention discloses a mica plate mounting structure of a power battery, and relates to the technical field of mica plate mounting structures, the mica plate mounting structure comprises a battery shell, the battery shell comprises a top shell plate, a battery cell is mounted in the battery shell, the mica plate mounting structure further comprises two groups of mounting assemblies, and the two groups of mounting assemblies are mounted on the inner wall of the battery shell between the top shell plate and the battery cell; the two groups of mounting assemblies are symmetrically arranged relative to the vertical central axis of the battery shell; the mica plate is mounted between the two mounting assemblies; and the torsion assembly is mounted in the mounting assembly. Through cooperation of structures, when thermal runaway occurs in a battery cell of the power battery and an acting force generated by impact of high-pressure gas on the mica plate exceeds a preset value, the torsion assembly controls the mica plate to be bent towards the direction close to the battery cell, so that the mica plate is slightly bent into an arc shape, and the impact force borne by the plane of the mica plate can be dispersed; therefore, the compressive strength is improved.

    本发明公开了动力电池的云母板安装结构,涉及云母板安装结构技术领域,包括电池壳,所述电池壳包括顶壳板,且所述电池壳内安装有电芯,还包括:两组安装组件,两组安装组件安装在顶壳板与电芯之间的电池壳内壁,且两组安装组件关于电池壳的竖直中轴线对称设置;云母板,所述云母板安装在两个安装组件之间;安装在安装组件内的扭转组件。本发明通过结构之间的配合,在动力电池的电芯出现热失控时,当高压气体对云母板冲击所产生的作用力超过预设值时,扭转组件控制云母板向靠近电芯的方向弯曲,使云母板轻微弯曲为圆弧状,使其可以分散其平面所受到的冲击力,从而提高其抗压强度。
