Abstract

A rechargeable lead-acid battery cover has a casing, two power outlet line through-holes, a circuit board and a charging assembly seat. The casing is provided with a holding space, and the power outlet line through-holes are set at one side of the holding space for penetration of anode and cathode leads, and also for electrical connection with the positive/negative contacts of the lead-acid battery. The circuit board is assembled into the casing'"'"'s holding space, and connected to the positive and negative contacts through anode and cathode supply lines. A charging assembly seat is set on the circuit board and also electrically connected with anode and cathode supply lines, while the charging assembly seat is connected with a charging power source, and the lead-acid battery is charged through anode and cathode supply lines. The lead-acid battery can be protected and the charging function can be guaranteed.

Claims

1. A rechargeable lead-acid battery cover, which is assembled onto the positive and negative contacts of an existing lead-acid battery;

said cover comprising;

a casing;

with a casing outlet set at a bottom thereof; and

a holding space is set in the casing;

two power outlet line through-holes;

set at one side of the holding space for penetration of anode and cathode leads of a power outlet line;

moreover, the anode, and cathode leads firstly penetrate into the holding space from the two power outlet line through-holes, and then pass through the casing outlet to connect electrically with the positive, and negative contacts of the lead-acid battery;

a circuit board;

assembled into the holding space of the casing;

the circuit board is connected to the positive and negative contacts of the lead-acid battery via anode and cathode supply lines;

a charging assembly seat;

arranged onto the circuit board and connected electrically with the anode and cathode supply lines;

the charging assembly seat is used for connection with a charging power source, and then the lead-acid battery is charged through the anode and cathode supply lines;

a power supply assembly seat;

which is connected electrically with the anode and cathode supply lines;

a light-emitting module;

set on the circuit board;

the light-emitting module comprises a control circuit, at least a light-emitting unit, a switch used to control the switching on and off of the light-emitting unit and a multi-segment button used to regulate the glow threshold of the light-emitting unit;

the light-emitting unit is protruded from one side of the casing;

a power indicator light;

protruded from a preset location of the casing, and also electrically connected with the control circuit of light-emitting module; and

a charging indicator light, protruded from a preset location of the casing, and also electrically connected with the control circuit of light-emitting module.
