Problems solved by technology

[0002] The battery liquid injection hole needs to be sealed with a sealing plug, and some existing battery top cover structures use welding and plastic nails to double seal the liquid injection hole, and the production process is complicated, and the sealing function is redundant; some battery top cover structures also use steel balls Sealing, which presses the steel ball into the liquid injection hole forcibly, requires high rigidity of the top cover sheet structure, and is easy to cause metal chips to fall into the battery cell, there is a risk of short circuit, and the reliability of the seal is not good

Embodiment

[0032] see figure 1 , figure 1 It is a schematic cross-sectional structure diagram of the top cover structure 10 provided by the embodiment of the present invention.

[0033] The embodiment of the present invention provides a top cover structure 10, the top cover structure 10 has the characteristics of simple structure, easy processing and production, and high sealing reliability. The top cover structure 10 can be applied to the battery. When the top cover structure 10 is applied to the battery, the top cover structure 10 can be installed on the top of the battery cell to be electrically connected to the pole piece of the battery cell, and can be connected to the shell of the battery cell. The battery is connected to form a closed space. Since the battery adopts the top cover structure 10 provided by the embodiment of the present invention, the battery also has the characteristics of simple structure, easy processing and production, and high sealing reliability.

Abstract

The invention discloses a top cover structure and a battery, and relates to the technical field of battery sealing. The top cover structure comprises a top cover piece and a sealing nail, a liquid injection hole is formed in the top cover piece, and the sealing nail has elasticity and is matched with the liquid injection hole so as to seal the liquid injection hole when the sealing nail is pluggedinto the liquid injection hole. The top cover structure and the battery have the characteristics of simple structure, convenience in processing and production and higher sealing reliability.

Description

technical field [0001] The invention relates to the technical field of battery sealing, in particular to a top cover structure and a battery. Background technique [0002] The battery liquid injection hole needs to be sealed with a sealing plug, and some existing battery top cover structures use welding and plastic nails to double seal the liquid injection hole, and the production process is complicated, and the sealing function is redundant; some battery top cover structures also use steel balls Sealing, which presses steel balls into the liquid injection hole, requires high rigidity of the top cover sheet structure, and is easy to cause metal chips to fall into the battery cell, there is a risk of short circuit, and the reliability of the seal is not good. [0003] In view of this, it is particularly important to develop and design a top cover structure and battery that can solve the above technical problems. Contents of the invention [0004] The purpose of the present...
