Thermal battery stack structure in large-scale mechanical environment

The thermal battery stack structure under the large-scale mechanical environment comprises a lower fixing plate and a battery shell bottom and is characterized in that the lower fixing plate is provided with a series of protruding clamping grooves and weight reducing grooves, the battery shell bottom is provided with a series of grooves, and the protruding clamping grooves and the grooves are consistent in number, shape and thickness and can be installed in a close-fitting mode. The invention has the beneficial effects that a series of convex clamping grooves and groove structures are designed between the lower fixing plate and the bottom of the battery shell, so that the problems of drainage strip breakage and battery failure caused by rotation of an electric pile in the battery shell under the condition of a large-scale mechanical environment in the prior art are effectively solved. The structure is simple and easy to use, and the overall structural reliability of the thermal battery and the stability of cu
