A rack-and-pinion annular battery device with self-replacement function

Abstract

Specifically, the invention is a rack-and-pinion annular battery device with a self-replacement function, which solves the problem that existing annular battery packs are difficult to detect and replace and affect maintenance efficiency during use. A rack and pinion annular battery device with self-replacement function, the inner cavity of the annular track groove is provided with a working battery and an insulating column, and a fixed contact is arranged outside the annular track groove, and one of the working batteries is arranged below There is a battery drop hole, and an arc-shaped operation window is arranged on the inner side; a rotating support cylinder is fixedly connected between the spare battery storage rack and the damaged battery storage rack, and the outer wall of the rotating support cylinder is extended with a radial claw, and the radial dial The claw extends into the operation gap; the push rod of the vertical push rod faces downward; the output shaft of the stepping motor is fixedly installed in the rotating support cylinder; the control part includes a micro control unit. The invention realizes automatic detection and replacement of damaged batteries, and the maintenance efficiency is greatly improved.

Description

technical field [0001] The invention relates to battery replacement technology, in particular to a rack-and-pinion annular battery device with self-replacement function. Background technique [0002] With the development of modern technology, traditional square or cylindrical lithium batteries are difficult to meet the needs of some special-shaped electronic products with ring or circular structures. Connecting lithium batteries in series or in parallel to form a ring-shaped battery pack can not only ensure its capacity and use safety, but also better match the ring structure or circular structure of electronic products. [0003] However, practice has shown that the existing ring-shaped battery packs have the following problems in use: one is that each battery in the ring-shaped battery pack is connected in parallel or in series, and individual battery damage will directly affect the use of the entire ring-shaped battery pack. Each battery unit in the battery pack is manual...
