Abstract:
A box (10), a battery (100), a powered device, and an assembly method for the box (10). The box (10) comprises a first box (11), an accommodating recess (12), a sealant (13) and a second box (14). The first box (11) has an opening (111). The accommodating recess (12) is arranged in the circumferential direction of the opening (111). The sealant (13) is accommodated in the accommodating recess (12). The second box (14) is provided with a circumferentially arranged bonding portion (141), and the bonding portion (141) is configured to extend into the accommodating recess (12) and be bonded with the sealant (13) when the second box (14) covers the opening (111), so as to achieve sealing connection between the first box (11) and the second box (14). The accommodating recess (12) can limit the sealant (13), such that the sealant (13) will not deviate into the accommodating recess (12), thereby preventing the occurrence of sealing failures and ensuring the sealing performance of the sealant (13).
