Description

a rechargeable battery

technical field

The utility model relates to a rechargeable battery, in particular to a rechargeable battery which can be used bidirectionally and can realize linkage control.

Background technique

Currently used cylindrical alkaline batteries, lithium batteries, etc., are equipped with positive and negative electrodes at both ends of the battery, traditional portable electrical products, according to the electrode distribution of the existing battery, generally only consider the battery as a device to provide power, How to play the application field of the battery has not been studied too much. The patent application number is 97116803.2, which discloses a combined structure of rechargeable batteries that can be used in both directions. It integrates the working battery and the backup battery on a housing, and is provided with an inlaid plug and a battery at both ends of the housing. The contact electrode is connected with the main body of the mobile phone. When the working battery is used up, the battery case can be adjusted to connect the spare battery and continue to be used. This battery structure can prolong the use time of the mobile phone, save energy, and greatly facilitate users. This scheme improves the structure of the battery, but this improvement is only based on dividing the original battery into a working battery and a backup battery, and fails to escape the thinking that the battery is only used as a power supply device.

Utility model content

The problem to be solved by the utility model is to provide a rechargeable battery with simple structure, high practicability, which can cooperate with the control switch of the electric equipment to realize linkage control.

According to the above-mentioned problems to be solved, a rechargeable battery has been designed, including a shell and a shell cover, a lithium battery core placed in the shell, a PCB protection plate connected to the lithium battery core, a positive lead, a negative lead, and a shell at both ends of the shell A positive conductor is arranged on the cover, and the positive conductor is connected to the positive lead wire. A conductive metal sheet or a metal ring is also arranged on the casing cover, and the conductive metal sheet or metal ring is connected to the PCB protection board; a negative electrode conductor is arranged on the outside of the casing, The negative electrode conductor is connected to the negative electrode lead.

The positive electrode conductor is copper particles, and the negative electrode conductor is elastic copper sheet.

The rechargeable battery of the utility model changes the structure of a traditional battery in which one end is a positive pole and the other end is a negative pole. It has positive poles at both ends and the negative pole is on the side. According to the structural characteristics of this kind of rechargeable battery, it can be used in electrical appliances that require multiple control switches, and each switch can realize the control of electrical appliances. If it is applied to a flashlight, a control switch is provided on the lamp tail, the lamp cap or the lamp body of the flashlight, and each control switch can realize the control of the flashlight, which is suitable for users with different usage habits. The utility model brings into play new functions of the battery by changing the structure of the battery, so that the battery has more application fields.
