[specific embodiment]
It is clear in order to be more clear the purpose of this utility model, technical solution and advantageous effects, below in conjunction with attached
Figure and specific embodiment, the present invention will be further described in detail.It should be understood that described in this specification
Specific embodiment is not intended to limit the utility model just for the sake of explaining the utility model.
Fig. 1 and Fig. 2 is please referred to, the utility model provides a kind of lithium ion battery liquid injection bore seal assembly, including shell top
Lid 10, sealing nail 30 and sealing cover 40.The Casing top 10 includes opposite top surface 11 and bottom surface 12, the Casing top
10 offer the liquid injection hole 20 through top surface 11 and bottom surface 12, and the liquid injection hole is surrounded on the top surface 11 of the Casing top 10
20 are equipped with the annular boss 13 being spaced with liquid injection hole 20, and the outside of the annular boss 13 is equipped with external screw thread.In actual operation,
The liquid injection hole 20 is preferably opened on Casing top 10, can also be opened up in the housing sidewall of battery according to the actual situation
Liquid injection hole 20, this also should be regarded as specific embodiment of the utility model.
The sealing nail 30 includes rivet nut 31 and the nail lid 32 connecting with rivet nut 31, and the radial dimension of the nail lid 32 is greater than
The radial dimension of rivet nut 31.The rivet nut 31 is integrally formed with nail lid 32 and the ruler of the size of the rivet nut 31 and liquid injection hole 20
