Description

Voltage adjustable mobile lead-calcium battery

The utility model relates to a voltage-adjustable mobile lead-calcium accumulator, in particular to an accumulator capable of adjusting the output voltage and providing various electrical appliances below 12 volts when going out.

Today's portable electrical appliances, such as mobile phones, electric shavers, walkmans, palmtop computers, laptop computers, etc., each have a limited battery or hidden battery, and each has a matching The power supply (commonly known as the charger) can be used for charging; if the power of the battery is exhausted, the spare hidden battery can be used, and if the power of the hidden battery is also exhausted, only the power supply can be used for charging. And can use portable electrical appliances at the same time.

However, some portable electrical appliances do not have hidden batteries for backup, such as laptop computers, etc., or no general standard batteries are available, such as mobile phones, laptop computers, etc., and can only use power when the batteries are exhausted However, if there is no AC power supply for charging, it can no longer be used, and the backup power cannot be provided by ordinary standard batteries, thus causing troubles for users.

Furthermore, the general standard battery can provide limited power and cannot provide a long use time. If you want to go out for a long time, and you are afraid that the battery you carry is not enough, you must carry more batteries, thus causing users inconvenience and hassle.

And if traveling abroad, if the battery is exhausted and needs to be charged, because the voltage and plug specifications of each country are different, even if there is a power supply for charging, it cannot be used directly.

In addition, general lead-acid batteries only have a fixed output voltage, such as 2 volts, 6 volts, ... etc.; and because they can only output a fixed voltage, they cannot be directly applied to various electrical appliances.

The main purpose of this utility model is to provide a voltage-adjustable mobile lead-calcium storage battery. The output voltage of the battery can be adjusted, and can provide users with voltages below 12 volts for various electrical appliances when they go out.

The purpose of this utility model is achieved in the following way: a voltage-adjustable mobile lead-calcium storage battery, a plurality of tank chambers are separated in a battery box, and a positive plate, a separator and a negative plate are built into the tank chamber to form a storage battery. And a side chamber is arranged in the battery box, and a circuit board with a variable resistance and a power output socket is installed in it, and the variable resistance and the socket are located on the outside of the battery box.

The variable resistor can be a band switch.

The utility model has a reasonable and simple structure, is convenient to carry, can output an adjustable voltage below 12V, and provides greater convenience for users.

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Fig. 1 is the perspective view of the utility model;

Fig. 2 is a three-dimensional exploded view of the utility model;

Fig. 3 is the schematic circuit diagram of the utility model.

First of all, referring to Fig. 1 and Fig. 2, a battery box 1 is mainly divided into a plurality of tank chambers 11, and a positive plate 12, a separator 13 and a negative plate 14 are built in each tank chamber 11 to form a storage battery. And be provided with a side room 15 in this battery box 1, be equipped with a circuit board 2 with variable resistor 21 and power output socket 22 in it, as shown in Figure 3, and this variable resistor 21 and socket 22 are positioned at the battery appropriate position outside box 1.

According to the above-mentioned structure, a portable electrical appliance 3 power cord 31 must be plugged into the above-mentioned socket 22, and the voltage used by the portable electrical appliance 3 can be adjusted by the variable resistor 21, so that the portable electrical appliance 3 When the battery is exhausted and there is no AC power supply for charging the power supply, an additional backup power supply is provided to solve the situation of lack of power available.

The variable resistor 22 on the circuit board can be positioned and segmented to output different voltage values, such as 2 volts, 3.8 volts, 4.5 volts, 6 volts, 7.2 volts, 9 volts, 12 volts, etc., so the output voltage has a wide range of use. Therefore, it is necessary to provide a variety of portable electrical appliances for use, so that users who use a variety of portable electrical appliances can switch between them.

Furthermore, when the electric energy of the utility model is exhausted, it can also be recharged, so that it can be recharged for backup, and thus can be used repeatedly.

And because the utility model is cheaper than general metal batteries (such as lithium batteries), it must be accepted by consumers; and the power storage capacity is good, and it must have a longer service time; and the integrated structure can avoid Carry a lot of known standard batteries; therefore, it is very convenient for consumers to carry and use.

In addition, the variable resistor 21 can be changed into a band switch as required, and the purpose of adjusting different output voltages can also be achieved.
