It is understandable for the above objects, features and advantages of the present invention is enable to become apparent, below in conjunction with the accompanying drawings to the present invention Specific embodiment explain in detail.
With reference to Fig. 1, an embodiment of the present invention provides a kind of power supply adaptor, the power supply adaptor can include：It is suitable for With the DC power source adapter 1 of DC power supply coupling.The DC power source adapter 1 can include：Battery pack interface unit 11 And interface connection module group 12.Wherein：
The battery pack interface unit 11 is positive integer including battery packet interface 1~N, N including multiple battery packet interfaces. 1~N of the battery packet interface is suitable for the battery pack of access relevant voltage；
The interface connection module group 12, including input, output end and be coupled to the input terminal and output terminal it Between more than two 1~N of interface connection module.1~the N of interface connection module and 1~N of the battery packet interface is corresponded And it couples, and coupled between the 1~N of interface connection module according to preset connection mode.
In specific implementation, in the battery pack interface unit 11, the quantity of battery packet interface is not restricted, the interface Interface connection module is not also restricted in link block group 12, as long as the battery packet interface and the interface connection module are one by one Corresponding and coupling.
For example, referring to Fig. 2, the battery pack interface unit 11 can set 2 battery packet interfaces, and respectively battery pack connects Mouth 111 and battery packet interface 112.Correspondingly, the interface connection module group 12 can set 2 interface connection modules, respectively For interface connection module 121 and interface connection module 122.Battery packet interface 111 is corresponding with interface connection module 121 and couples, Battery packet interface 112 is corresponding with interface connection module 122 and couples.
For another example, with reference to Fig. 3, the battery pack interface unit 11 can set 3 battery packet interfaces, and respectively battery pack connects Mouth 111,112 and 113.Correspondingly, the interface connection module group 12 can set 3 interface connection modules, respectively interface Link block 121,122 and 123.Battery packet interface 111 is corresponding with interface connection module 121 and couples, battery packet interface 112 with Interface connection module 122 is corresponded to and is coupled, and battery packet interface 113 is corresponding with interface connection module 123 and couples.
In specific implementation, in the battery pack interface unit 11,1~N of battery packet interface allows to access battery pack Voltage may be the same or different, and each battery packet interface allows the voltage for accessing battery pack not to be restricted.Specifically Each battery packet interface allows the voltage for accessing battery pack that can be configured according to actual demand.It is understood that nothing By battery packet interface each in the battery pack interface unit 11 allow access battery pack voltage how, do not form to this The limitation of invention, and within protection scope of the present invention.
For example, with reference to Fig. 2, battery packet interface 111 and battery packet interface 112 can be identical, for example, battery packet interface 111 and The voltage that battery packet interface 112 allows to access battery pack can be 60V or 30V.Battery packet interface 111 and battery pack connect Mouthfuls 112 can also be different, for example, the voltage that battery packet interface 111 allows to access battery pack can be 60V, battery packet interface 112 voltages for allowing to access battery pack can be 30V.
Since the quantity of the battery pack of access battery packet interface is transformable, so that DC power source adapter 1 Output voltage is transformable, and by the way that battery packet interface is rationally set to allow the voltage of access battery pack, it is straight can to meet friendship Flow voltage requirements of the tool of power drives under different operating modes.
In specific implementation, the structure of the battery packet interface may have a variety of, and the knot of each battery packet interface Structure may be the same or different, and not be restricted specifically, as long as having access to the battery pack of relevant voltage, and will be accessed The voltage of battery pack is exported by corresponding interface connection module.
