Abstract

The invention provides a button battery shell structure, a button battery and an electric device, related to the technical field of batteries. A lower cover comprises a second sidewall upper segment and a second sidewall lower segment; diameter of the second sidewall upper segment is greater than the diameter of the second sidewall lower segment; a sealing ring is mounted between an upper cover and the lower cover; altitude of the sealing ring is adaptive to the altitude of the second sidewall upper segment, the sealing ring is mounted in an inner cavity of the second sidewall upper segment; the upper cover is mounted in the inner cavity of the second sidewall upper segment, and a battery core is mounted in the inner cavity of the second sidewall lower segment. The second sidewall lower segment bears pressure of expansion of the battery core and cannot deform, moment of force of the second sidewall upper segment decreases, pressure provided increases, by combination of the two aspects,the battery is guaranteed to not deform even under a condition of expansion of the battery core and internal pressure, and cannot leak liquid. Consequently, technical problems above are solved. Meanwhile, since reduction of size of the upper cover and the sealing cover, effective volume of the inner cavity is increased, a bigger battery core is allowed to be installed, and battery capacity is improved effectively.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a shell structure of a button battery, a button battery and electrical equipment. Background technique [0002] A button cell, also known as a button cell, refers to a battery that looks like a small button, generally speaking, with a larger diameter and a thinner thickness. Button batteries are widely used in various miniature electronic products due to their small size, with diameters ranging from 4.8mm to 30mm and thicknesses ranging from 1.0mm to 7.7mm; they are generally used as backup power for various electronic products, such as Computer motherboards, electronic watches, electronic dictionaries, electronic scales, remote controls, electric toys, pacemakers, electronic hearing aids, counters and cameras, etc. [0003] Button batteries are also divided into two categories: chemical batteries and physical batteries, and chemical batteries are the most commonly used. They...
