Taking a smart phone as an example below, how the adapter in this embodiment implements data transmission and charging between two mobile phones will be described in detail.

Assuming that two mobile phones are mobile phone A and mobile phone B, that is, the first terminal corresponds to mobile phone A, and the second terminal corresponds to mobile phone B, then the method for realizing data transmission and charging of two mobile phones is shown in Figure 2, mainly including the following step:

Step S11, connect the first connector of the adapter to the data transmission interface of the mobile phone A, and connect the second connector to the data transmission interface of the mobile phone B.

Wherein, the method of connecting the first connector and the second connector to the mobile phone can be a plugging method.

In addition, for different types of mobile phones, the corresponding types of connectors are also different. For example, for Apple mobile phones, the connector that needs to be configured to connect to it is a male head that is compatible with the data transmission interface of the Apple mobile phone. For Android phones, it needs to be configured to connect to it. The connector is a male head adapted to the data transmission interface of the Android phone. Moreover, the design of the first joint and the second joint needs to meet the requirements of enabling data transmission between two different mobile phones. In this case, a corresponding conversion joint or data transmission line can be set between the first joint and the second joint to Realize the communication between the Apple mobile phone and the Android mobile phone, such as the conversion joints involved in the patent CN205081332U, the patent CN20515972U and other documents, which can be used between the first joint corresponding to the Apple mobile phone and the second joint corresponding to the Android mobile phone, so as to connect the two joints After connecting to the corresponding data transmission interface, data transmission can be performed between the two mobile phones.

Step S12, inserting the adapted charging cable of the mobile phone A or mobile phone B into the extension interface of the adapter.

Among them, if mobile phone A and mobile phone B have different types of compatible charging cables, the type of the expansion interface needs to be configured according to the actual situation. For example, to charge an Apple mobile phone, the type of the expansion interface needs to be adapted to the charging line of the Apple mobile phone. For an Android mobile phone, the type of the expansion interface needs to be adapted to the charging line of the Android mobile phone. Here, for an Android mobile phone, the matching charging cable is generally a Micro-USB data cable, and the expansion interface is a corresponding Micro-USB interface, and the corresponding expansion interface of an Apple mobile phone can also be configured accordingly.

Step S13, operating mobile phone A and/or mobile phone B to perform data transmission between mobile phone A and mobile phone B.

This step is to complete the corresponding data transmission function by operating the mobile phone, such as selecting a certain picture from mobile phone A, and sending the picture to mobile phone B through touch screen operation, mobile phone B receives the picture from mobile phone A, and It is stored in the selected folder.

Step S14, connect the adapted charging cable of mobile phone A and/or mobile phone B to the adapted charging head, and then plug the charging head into a corresponding power source to charge the corresponding mobile phone.

This step is a conventional charging operation, and the power source can be a 220V fixed electrical socket, or a mobile power source such as a power bank.

It should be noted that during actual operation, the user can adjust the operation sequence of steps S11-S14 according to his own habits, and this embodiment does not limit the execution sequence of steps S11-S14.

In addition, on the basis of the above steps S11-S14, for the situation where the first expansion interface and the second expansion interface are preferably configured above, it is also possible to add a storage device, read the data in the storage device, and transfer the data in the mobile phone The step of storing to said storage device.

Accordingly, the adapter of this embodiment can realize the function of "one for three", that is, the three functions of data transmission, charging and data storage between two mobile phones can be realized simultaneously by using the adapter.

Embodiment two

The inventive idea of the second embodiment is the same as that of the first embodiment. According to the above, the first joint and the second joint of the adapter of the present invention can be configured according to the data transmission interface type of the mobile phone, and the joint and data in the first embodiment The transmission interfaces are connected by plugging. On the basis of the first embodiment, this embodiment proposes a scheme that can realize the adsorption connection between the connector and the interface. The adapter is inserted into the interface, while in the second embodiment, the connection between the joint and the interface is realized by means of adsorption.

As shown in Figure 3, this embodiment presents another adapter 1, which includes: a first connector 11, used to adsorb to the data transmission interface of the first terminal; a second connector 12, used The data transmission interface adsorbed to the second terminal; and the expansion interface 13, which is electrically connected to the first connector and the second connector, and is connected to the charging line of the first terminal and/or the second terminal match.

Compared with Embodiment 1, in this embodiment, the connection between the connector and the interface is realized by means of adsorption, so structurally, the first connector 11 and the second connector 12 are built inside the two ends of the flat shell 14 in this embodiment, so that It is more conducive to the formation of the adsorption of joints and interfaces.

Other implementation details of the adapter in this embodiment are the same as or similar to those in Embodiment 1, and will not be repeated here.

In this embodiment, the scheme for realizing the adsorption of connectors and interfaces is applicable to various types of interfaces. It is a type-c terminal, and the type-c interface and the connector in the structure in Figure 3 are easily connected by adsorption.

As shown in Figure 4, many smart terminals are equipped with type-c interface 2 at present. The type-c interface is a new type of USB interface that is as thin, light and compact as the Lightning interface. c terminal has also been favored by more and more users.

However, for a terminal only provided with a type-c interface, the user must use a data cable with a type-c first connector to connect to it. However, the existing type-c data cable can only be single-sided (that is, only one end has a type-c first connector) and has a relatively long length, and correspondingly configure the first connector of the adapter of this embodiment as After the type-c connector, the type-c data cable can be used for data transmission between two terminals, which is beneficial to save costs. In addition, the type-c connector is connected to the type-c interface by plugging. This plugging method is not easy to disconnect, so when people or objects accidentally trip over related data lines (such as data transmission lines and charging lines, etc.), due to The plugging method is not easy to disconnect, and it is easy to cause pulling and breaking the terminal. Therefore, considering the characteristics that the front and back sides of the type-c interface can be inserted, it can be known that for the type-c interface, this embodiment adopts the adsorption method to make the connector and the type-c interface Interface connection, this adsorption method is easy to realize the disconnection of the connector and the interface, which is more conducive to ensuring the safety of the terminal.

In this regard, on the basis of the first embodiment, this embodiment also proposes a double-sided magnetic conversion assembly 3, as shown in Figure 5, the double-sided magnetic conversion assembly 3 includes: a first magnetic head 31, It is used to be plugged into the data transmission interface of the first terminal 41 to convert the data transmission interface into a first magnetic suction data transmission interface; the second magnetic head 32 is used to be plugged into the data transmission interface of the second terminal 42 to convert the data transmission interface The data transmission interface is converted into a second magnetic suction data transmission interface; and the adapter 1 in the first embodiment, and the first joint 11 of the adapter 1 is adsorbed to the first magnetic suction data transmission interface , the second connector 12 is attracted to the second magnetic data transmission interface.

In this embodiment, the data transmission interface is a type-c interface 2, so that the magnetic data transmission interface is a magnetic type-c interface, and the corresponding first joint 11 and the second joint 12 is a type-c connector.

Further, the first magnetic head 31 and the second magnetic head 32 are preferably T-shaped, which are inserted into the type-c interface of the terminal to expose the pin pins in the type-c interface to the outside to form an externally leaking female port, and the first joint 11 and the second joint 12 of the adapter 1 are corresponding male ports, and the first joint 11 and the second joint 12 are provided with a magnetically permeable substance, so as to be compatible with the first magnetic head 31 and the second joint. The two magnetic heads 12 form an adsorption effect, which is similar to the adsorption effect between the magnetic pole N and the magnetic pole S. When the user places the adapter near the mobile phone with the magnetic head inserted, the first joint 11 will be automatically attracted to the first magnetic head 31 under the influence of the adsorption between the magnetic head and the magnetic material, thus realizing the first joint 11 For connection with the type-c interface of the first terminal, the second connector 12 will be automatically attracted to the second magnetic head 32, thereby realizing the connection between the second connector 12 and the type-c interface of the second terminal.

Still assuming that the first terminal and the second terminal are mobile phone A and mobile phone B respectively, taking the type-c interface as an example, the method for realizing data transmission and charging of two mobile phones in this embodiment is shown in Figure 6, which may specifically include The following steps:

Step S21, inserting the first magnetic head into the type-c interface of mobile phone A, and inserting the second magnetic head into the type-c interface of mobile phone B.

Step S22 , attaching the first joint of the adapter to the first magnetic head, and attaching the second joint of the adapter to the second magnetic head.

In this way, OTG data transmission between mobile phone A and mobile phone B can be performed.

Step S23, plugging the corresponding matching charging cable into the extension interface of the adapter.

In this way, if the expansion interface is plugged with the matching charging cable of mobile phone A, then after the first connector is adsorbed to the first magnetic head, mobile phone A can be charged, and the method of charging mobile phone B is similar to this. Say more.

Part of the implementation details in the above steps S21-23 are the same as those in the first embodiment, and will not be repeated here.

The double-sided magnetic conversion assembly of this embodiment realizes the magnetic connection between the adapter and the type-c interface of the terminal. Since the type-c interface has the characteristics that both sides can be inserted, the user only needs to place the converter on any Placed near the terminal, the adapter can be automatically attached to the type-c interface of the terminal. This method simplifies the user's operation, and does not need to configure an additional OTG data cable between the two terminals, which saves costs, and the adsorption method is easier to disconnect than the plug-in method, so that when people or things are tripped by charging cables, etc. At that time, the connector can be disconnected from the terminal in time to prevent the terminal from being dropped.

To sum up, the embodiment of the present invention enables two terminals, especially two type-c terminals, to realize their own charging while performing data transmission, and also through the design of magnetic connectors and interfaces, the terminals can be When pulled, the adapter is automatically disconnected from the terminal to prevent the terminal from being broken, and the design of the magnetic connector and interface helps to avoid electromagnetic interference and has better stability.

The preferred embodiment of the present invention has been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the specific details of the above embodiment, within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, These simple modifications all belong to the protection scope of the present invention.

In addition, it should be noted that the various specific technical features described in the above specific implementation manners may be combined in any suitable manner if there is no contradiction. In order to avoid unnecessary repetition, various possible combinations are not further described in the present invention.

In addition, various combinations of different embodiments of the present invention can also be combined arbitrarily, as long as they do not violate the idea of the present invention, they should also be regarded as the disclosed content of the present invention.
