Description

power supply for flashlight

[technical field]

The utility model relates to a power supply device, in particular to a power supply for a flashlight.

[Background technique]

Flashlight - because it is easy to carry and safe to use, it is widely used in daily life and has become an indispensable daily necessities for home travel.

At present, the power supply of flashlights sold on the market generally adopts dry batteries, which are replaced immediately when used up, have no charging function, and cannot be used repeatedly; secondly, the batteries of rechargeable lighting lamps are generally large, and it is very inconvenient to carry. For this reason, it is necessary to improve the power supply device of the existing flashlight, which is convenient for repeated use and convenient charging.

[utility model content]

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a power supply for the flashlight which is simple in structure, easy to use and can be charged by AC or DC.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions:

A power supply for a flashlight, which includes a housing and a rechargeable battery, the two opposite ends of the housing are respectively equipped with positive and negative conductive sheets, and it is characterized in that the housing is provided with a circuit board for AC and DC charging, A charging plug is articulated on the casing, and the charging plug is connected to the above-mentioned circuit board through a guide line; there is also a jack on the casing, and a contact that can be directly plugged into the power supply of the car is built in the jack, and the contact is connected to the above-mentioned circuit board. The boards are connected via the conductor wires;

The power supply for the flashlight as described above is characterized in that a charging indicator connected to the circuit board is mounted on the housing;

The power supply for the flashlight as described above is characterized in that there are three or more batteries, and each battery is installed in the housing after being connected in series;

The above-mentioned power supply for the flashlight is characterized in that the housing is composed of upper and lower housings, the upper housing is clamped on the lower housing, the upper housing is provided with a cavity, and the charging plug is hinged in the cavity in the above-mentioned cavity. The fixed block is rotatably attached to the cavity bottom of the concave cavity.

The beneficial effects of the utility model are: the housing is provided with a circuit board for AC and DC charging, and a charging plug connected to the circuit board through a guide line is movably hinged on the housing, and the charging plug is inserted into the power socket at home, and the current passes through the circuit After the board, the battery can be charged with AC power; at the same time, there is a jack on the shell, and the jack has a built-in contact that can be directly plugged into the car power supply. The battery has been charged, so that it is not only suitable for home use, but also suitable for travel, and there is no need to worry about charging, which is convenient and practical.

[Detailed ways]

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

As shown in the figure, the power supply for the flashlight includes a housing 1 and rechargeable batteries 2. There are two or more batteries 2, and each battery 2 is installed in the housing 1 after being connected in series. In the utility model, three rechargeable C-type batteries can be contained in the casing 1 . The two opposite ends of the housing 1 are equipped with positive and negative conductive sheets 11 and 12 respectively. The housing 1 is provided with a circuit board 3 for AC and DC charging. A charging plug 4 is movably hinged on the housing 1. The charging plug 4 and The circuit board 3 is connected to each other through the power supply wire. When charging, the charging plug 4 is inserted into the power socket at home. After the current passes through the circuit board 3, the battery 2 can be charged with alternating current.

There is also a jack 13 on the housing 1, and the jack 13 has a built-in contact that can be directly plugged into the vehicle power supply, and the contact is connected to the above-mentioned circuit board 3 through a power line. Because it can be directly connected with the automobile, the charging voltage is 12V at this time, and the battery 2 can be charged with the DC point after the electric current on the automobile passes through the circuit board 3, so it is very convenient to charge when going out like this.

Wherein, the housing 1 is cylindrical, the housing 1 is composed of upper and lower housings 15, 16, the upper housing 15 is clamped on the lower housing 16, the outer surface of the upper housing 15 is provided with a concave cavity 150, and the charging plug 4 is hinged in the concave cavity The fixed block 151 in the 150 is rotatably attached to the cavity bottom of the concave cavity 150, which is convenient for storage and carrying.

In the utility model, the charging indicator light 14 connected to the circuit board 3 is mounted on the casing 1, so that the user can determine whether charging is convenient, which is convenient and practical.
