The method aims to form products as many as possible by a small number of modules, and ensures that the products have high precision, stable performance, simple structure and low cost on the basis of meeting the requirements, and the connection among the modules is as simple as possible.
Many devices can be in modularized design, so that the manufacturing cost and the use cost are effectively reduced, and the later maintenance and upgrading are facilitated. In the existing lamp equipment, especially the portable lamp equipment with a storage battery, the integrated structure design is often adopted, namely, different products can only reach corresponding functions, can not be assembled and combined, and can not be upgraded or recombined, so that the later use and maintenance are not facilitated, and the cost of the design updating product is increased.
Disclosure of Invention
Aiming at the problems that the existing lamp is difficult to maintain and upgrade in the later period of the use end and the cost of updating products by the design of the production end is high because the existing lamp is not generally in a modularized design, the invention provides an emergency storage battery which can be conveniently connected with other subsystems of the lamp through the modularized design.
The technical scheme adopted by the invention is as follows: a modularized emergency storage battery comprises a shell with a hollow structure and an electric storage device arranged in the shell, wherein electric energy is provided for external equipment through the electric storage device; the shell is provided with at least two sinking grooves with cross structures and is internally matched with connecting sheets; the center of the bottom of the sinking tank is provided with an A through hole penetrating through the shell, and the two opposite surfaces of the connecting sheet are respectively provided with a connector which can be inserted into the A through hole and is fixed through an expansion end with variable volume arranged at the insertion end part; the shell is fixedly clamped with another structure provided with a sinking groove through the connecting sheet, so that a modularized system is formed.

And B contains the charge indication module of U2, adopts a constant-current constant-voltage charger of TP4056 chip, and it has certain steady voltage detection function, and still has the function of preventing back flushing, is used for instructing charging, LED state pin that finishes through charge indication module provides control information for pilot lamp 19. The STDBY pin is mainly a battery charging completion indication end, when current charging is completed, STDBY is pulled down to a low level by an internal switch to indicate that charging is completed, and the STDBY pin is always in a high-resistance state; and the GHRG pin is a charging state indicating end, when the charger charges the battery, the CHRG pin is pulled down to a low level by the internal switch to indicate that the charging is in progress, otherwise, the CHRG pin is in a high resistance state. Wherein C is a protection module comprising U3 and Q1, is a lithium battery protection circuit adopting a DW01 chip, and is charge and discharge protection of a series lithium battery pack; when the battery pack is fully charged, the voltage difference between the single batteries can be ensured to be smaller than a set value, so that the single batteries of the battery pack are uniformly charged, and the charging effect in a serial charging mode is effectively improved; meanwhile, the overvoltage, undervoltage, overcurrent, short circuit and overtemperature states of all single batteries in the battery pack are detected, and the service life of the batteries is protected and prolonged; the undervoltage protection prevents each single cell from being damaged by overdischarge when the single cell is discharged for use. That is, when the input voltage of the C portion is too low, the oc output of U3 causes the S2 pin of Q1 to be low, and pulling the LX pin of U4 low causes a circuit normally discharging through U4 to be short-circuited, thereby preventing the battery 9 from being excessively discharged. And the part D is an amplifying module comprising U4 and adopting an FP6293 chip, and 5V current is amplified to 12V through a triode and an amplifying control chip, and is transmitted to an output connector 4 at an output end to supply electric energy to the LED lamp.
It should be noted that, the specific circuit connection diagram has been illustrated and shown in detail in fig. 9, and the type of chip adopted is also mentioned in the foregoing, the circuit connection relationship of the device is clear, and the specific principle is clearly shown by the structural diagram 9 and the foregoing description. Meanwhile, based on the specific principle of a single chip, a person skilled in the art can know the complete working mode and principle, so that the description is omitted here.
The invention is not limited to the above-described alternative embodiments, and any person who may derive other various forms of products in the light of the present invention, however, any changes in shape or structure thereof, all falling within the technical solutions defined in the scope of the claims of the present invention, fall within the scope of protection of the present invention.
