[0023] Among them, the front and rear ends of the lower adhesive component 31 are fixedly connected with a protective plate 34, the lower end of the protective plate 34 is flush with the bottom of the second battery cell 2, and the upper end of the protective plate 34 is flush with the top of the first battery cell 1, and the facing surfaces of the front and rear protective plates 34 are tightly attached to the upper adhesive component 32 and the front and rear ends of the first battery cell 1 and the second battery cell 2 respectively; due to the setting of the protective plate 34, the front and rear sides of the first battery cell 1, the second battery cell 2 and the connecting component 3 can be well protected, and surface bumps and collisions can prevent the first battery cell 1 and the second battery cell 2 from causing greater damage as a whole.
