Embodiment Construction

[0051] The embodiments of the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings. The following embodiments are only used to explain the technical solutions of the present invention more clearly, and therefore are only used as examples, and cannot be used to limit the protection scope of the present invention.

[0052] Such as Figure 1 to Figure 6 As shown, the button-type miniature rechargeable lithium battery structural assembly includes an upper casing 1, a lower casing 2, and a rubber ring 6; the upper casing 1 is buckled in the lower casing 2, and the upper casing 1 and the lower casing The side walls of 2 are sealed by a rubber ring 6.

[0053] The wall thickness of the rubber ring 6 is gradually thicker along the installation direction, and the gradual wall thickness of the rubber ring is 0.01-0.1 mm.

[0054] The upper shell 1 and the lower shell 2 both include a cup body 8. The cup mouth of the cup b...

Abstract

A buckle-type miniature rechargeable lithium battery structure member relates to the technical field of an electronic structure member and comprises an upper shell, a lower shell and a rubber ring, wherein the upper shell is buckled in the lower shell, and side walls of the upper shell and the lower shell are sealed by the rubber ring. By the buckle-type miniature rechargeable lithium battery structure member, the conflict between an explosionproof structure and a sealing structure in a traditional technology is solved, and the problems the pursuit of the explosionproof performance causes lowbattery assembly yield and the pursuit of the sealing performance causes low batter capacity are solved.

Description

Technical field [0001] The invention relates to the technical field of electronic structural parts, in particular to a button-type miniature rechargeable lithium battery structural assembly. Background technique [0002] With the introduction of my country’s new energy policy cameras, the rechargeable and reusable lithium battery industry has developed rapidly in recent years. Among them, the consumer electronics market occupies half of the country. The main application areas of the consumer electronics market include mobile phones, notebook computers, Tablet computers, wearable devices, etc. Among them, wearable devices are mainly smart bracelets, smart watches, and Bluetooth headsets. However, due to the relatively small size of wearable devices, they generally only need to be equipped with small-sized lithium-ion batteries. Therefore, the battery life of such smart wearable devices is relatively short. At present, major manufacturers are seeking to reduce power consumption whi...
