Background technique

The charger is mainly a device for charging digital products, but the chargers of the prior art have the following disadvantages:

1. Because the charger plug of the prior art is fixed on the charger body, the charger body is plugged into the power socket or power strip along with the plug when in use, so that not only the user needs a long connecting line to Connect the digital products that need to be charged with the charger body, and because the charger body has a large area, it will occupy a large area of the power socket or power strip, which will affect the use of other electrical appliances;

2. Because the structural design of the charger in the prior art is unreasonable, it occupies a large volume and is not very convenient to carry;

3. Because the use of USB cables is very frequent nowadays, such as charging of digital products, data transfer, etc. all need USB cables, but the chargers in the prior art do not come with USB cables. USB charging interface, so that it only has the function of charging, but not the function of data transfer. The function is relatively simple, and it also needs to carry additional data lines. It is easy to cause problems such as winding and carrying, causing relatively large troubles to users, and it is not very convenient to use.

Utility model content

The technical problem to be solved by the utility model is to provide a multifunctional charger that is convenient and comfortable to use, occupies a small volume, is convenient to carry and has various functions, so that users only need to carry this charger to replace all scattered charging equipment such as power supplies. Cables, chargers, charging or data cables, spare batteries, etc., and can be used to charge a variety of electrical appliances.

The technical solution adopted by the utility model is: a multifunctional charger, including a charger body, a circuit board arranged in the charger body, and an external charging plug electrically connected to the circuit board, the external charging plug and the charger One end of the main body is detachably connected and electrically connected to the circuit board through a connecting wire. The charger body is provided with an accommodating cavity for accommodating the connecting wire. The charger body is also provided with at least one installation slot. Each A functional component can be detachably connected in the installation groove, and each functional component is electrically connected with the circuit board, and the functional component includes a retractable USB component that functions as a USB connection line and a charging power component that functions as a storage of electric energy.

Compared with the prior art by adopting the above structure, the utility model has the following advantages: the external charging plug is detachably connected to the charger body and electrically connected to the circuit board through the connecting wire, so that the external charging plug can be connected to the charger body Remove it and plug it into the power socket or power strip, because the external charging plug is always electrically connected to the circuit board through the connecting wire, so as long as the external charging plug is inserted into the power socket or power strip, it can always supply power to the charger body , and the applicant only uses a longer connecting line to make the distance between the external charging plug and the charger farther, so that it is more comfortable and convenient to use, and will not affect the use of other electrical appliances; Cavity, you can place a long connecting line in the accommodating cavity, so that the connecting line will not be exposed outside when not in use, which is not only convenient to use, but also looks more beautiful; and at least one installation is set on the charger body slot, and you can detachably connect a functional component to each installation slot. If you set up a retractable USB component, when the charging line of the digital product is not long enough, you can pull out one of the USB plug connectors of the retractable USB component and connect it again. When it comes to digital products that need to be charged, or when a USB cable is needed for data transmission, the entire retractable USB assembly can be removed, because the retractable USB assembly is equivalent to a double-pull USB charging extension cable. It can be used as a USB cable. If the charging power supply component is set, when the external charging plug is connected to the external power supply, the circuit board will charge the charging power supply component, and when the external charging plug is disconnected, the charging power supply component will be charged.
