Safety device for preventing overcharge of battery

Abstract

The invention provides a safety device used for preventing a battery from being overcharged. The device comprises a box body, a through hole is formed in a left lower part of the box body; a rotatingshaft is mounted in the through holes through a bearing; a coaxial square hole is opened at a right end of the rotating shaft, a left side of a bottom side of a guide plate is an inclined surface inclined to the left, and the outer periphery of a right lever can slide along the inclined surface, a socket is fixedly installed on a top side of a through groove, a thru hole is formed in the middle ofa top side of the socket, and an upper end of a strip-shaped rack sequentially penetrates through the through groove and the thru hole and can move left and right and up and down in the through groove and the thru hole. The device has the advantages of simple structure, ingenuous concept, convenient use and operation, the charging time can be set, the charging time is not changed due to half-waypower failure, and after charging is finished, a charging plug can be separated from a charging socket, electric quantity loss in a storage battery is avoided, the aging of a connecting plug is delayed, meanwhile, battery overcharging caused by continuous charging is avoided, the mechanical timing is achieved, and the device is more reliable, convenient to maintain, capable of meeting market requirements and suitable for popularization.

Description

technical field [0001] The invention belongs to the field of charging devices, in particular to a safety device for preventing batteries from being overcharged. Background technique [0002] Existing chargers are generally equipped with an electronic module to prevent overcharging to avoid overcharging of the battery, and the anti-overcharging module is composed of a large number of electronic components, the structure is complex, it is not easy to maintain, and it is easy to be damaged and has low reliability, or Use an electronic timer to measure the charging time to prevent overcharging, but the timing is likely to be inaccurate after the power is cut off during the charging process, and the charger and the battery continue to be connected after charging is easy to consume the power in the battery or accelerate the aging of the connecting plug. Unable to meet the actual needs, so we invented a safety device for preventing the battery from overcharging. Contents of the i...
