(1) The first aspect

The following describes the modular multi-adaptive charger according to the embodiment of the present application with reference to FIGS. 1 to 5 .

Its modular multi-adaptive charger is shown in Figure 1 and Figure 2, including: a multi-adaptation body and a multi-adaptation circuit; the multi-adaptation body includes:

Charger body 1;

Assembled on the connecting pin 101 on the charger main body 1;

through the conversion plug 2 electrically connected to the connection pin 101;

The conversion plug 2 includes a conversion plug body 201 and conversion pins 202; the conversion pins 202 are arranged on one side of the conversion plug body 201; Connecting sockets are side socket 203 and counter socket 204 respectively.

The connecting pin 101 can be inserted into the side jack 203 or into the counter jack 204 to connect the charger main body 1 with the conversion plug 2, and the conversion plug 2 can be selected as a Chinese standard plug, an American standard plug, an Australian standard plug, or a European standard plug. One of the plugs or British standard plugs, by purchasing different types of conversion plugs 2 to adapt to the plug specifications of different regions. And by selecting whether to insert into the side jack 203 or into the pair jack 204, the relative assembly orientation of the charger body 1 and the conversion plug 2 can be adjusted, so as to avoid other electrical plugs on the plug strip and avoid mutual obstruction .

It can be seen that in the modular multi-adaptive charger provided by the present application, the conversion plug 2 and the charger body 1 are taken as a whole, and the conversion plug 2 can be replaced structurally to adapt to sockets of different standards. Connecting the adapter to the charger needs to increase the additional space of the charger and occupy a volume. The modular multi-adaptive charger provided by this application occupies less space on the plug strip and socket, and is more practical.

The multi-adaptation circuit includes: control circuit, power conversion circuit, control chip, communication module, internal circulation power supply circuit;

One end of the power conversion circuit is connected to the connecting pin 101 , and the other end is connected to the USB interface 102 . The control circuit, power conversion circuit, control chip, communication module, and internal circulation power supply circuit can all use existing circuits and existing chips, which will not be repeated here, and are arranged in the main body of the charger 1; the power conversion circuit is used to convert power , the control circuit is used to control the power conversion circuit, and collect the input voltage and output voltage of the power conversion circuit. The control circuit is connected to the power conversion circuit, the input end of the internal circulation power supply circuit is connected to the connection pin, and the output end is connected to the control circuit to supply power for the control chip; the control chip is respectively connected to the control circuit and the communication module. The control chip is used to communicate with the device to be connected through the communication module.

It can be seen that the 123 provided by the present application can also be adapted to sockets of different standards at the voltage circuit level to ensure safety.

Generally speaking, the diameter of the side hole 203 should be selected to be equal to the diameter of the counter hole 204, which is convenient for preparation and more beautiful.

In order to meet the charging safety and avoid the exposed jack from being accidentally touched, resulting in short circuit or electric shock hazard, the present invention makes the following settings:

On the conversion plug body 201, a slot 205 is opened along the closest route from the side jack 203 to the pair jack 204;

It also includes a rubber protective strip 3; the rubber protective strip 3 is installed in the groove 205; when one end of the rubber protective strip 3 covers one of the jacks, the other jack is exposed. The rubber protective strip 3 has flexibility, and when the rubber protective strip 3 slides in the groove 205 until the side jack 203 is covered, the jack is exposed and can be inserted. When the rubber protective strip 3 slides in the slot 205 until it reaches the insertion hole 204, the same is true.

The way that the rubber protection strip 3 is installed in the groove 205 can be selected from various existing feasible modes, so that the rubber protection strip 3 can move in the groove 205 and cannot be separated from the outside of the groove 205. For example, the relationship between the rubber protective strip 3 and the groove can be as shown in FIG. 3 . For specific other manners, those skilled in the art may use common sense to configure settings according to actual needs, and are not exhaustive here.

As preferably, as shown in Figure 4, the two ends of rubber guard strip 3 are concave semicircular arc shape, and the radius of concave semicircular arc shape is equal to the radius of side jack, because the radius of side jack is equal to the radius of jack , so the radius of the concave semicircular arc is also equal to the radius of the jack.

Furthermore, the difference between the length of the slot 205 and the length of the rubber protective strip 3 is the diameter of the side insertion hole 203 . The length H of the rubber protective strip 3 refers to the shortest length passing through the center of the concave semicircular arc as shown in FIG. 4 . Therefore, when the rubber protective strip 3 slides in the groove 205, it can be ensured that only one jack is exposed, and only the side jack 203 is exposed, or the jack 204 is exposed, which further ensures safety.

In a further embodiment, a USB interface 102 is provided on the main body of the charger 1;

It also includes a multifunctional data cable 4; one end of the multifunctional data cable 4 is a USB connector 401, and the other end is a Type-C interface male 402 and a Lightning interface male 403;

A storage slot 103 is provided on the main body 1 of the charger;

The multifunctional data line 4 is installed in the storage slot 103 .

In an optional embodiment, the outer surface of the rubber protective strip 3 is provided with convex points 301 for increasing frictional force, so as to facilitate pushing the rubber protective strip 3 to move in the groove 205 by hand.
