[0048] Second, after the semispherical groove 133 and the semispherical positioning block 12 are clamped, due to the existence of the connecting groove 134, the closed connecting groove 134 will have a negative suction effect with the semispherical positioning block 12, thereby doubling the connection strength of the two stacked standard battery modules 2.

[0049] Third, during the movement of the double battery module formed by subsequent stacking, the vibration generated by movement can be buffered by the elastic deformation of the plurality of rubber balls 132, thereby fully improving the stability of the double battery module structure and meeting the use requirement of convenient carrying.
