Fig. 2 to Fig. 3 is please referred to, is a kind of portable power of the embodiment of the present invention, including first the 1, second electricity of power supply Source 2 and third power supply 3.The bottom end face of first power supply 1 is equipped with first input end 10, and inside top wall is equipped with first Leading-out terminal 12, first input end 10 are separably electrically connected with external power supply 4 to from external power supply 4 to the first power supply The bottom outside wall of 1 power supply, second source 2 is equipped with the second input terminal 20, and inside top wall is equipped with second output terminal 22, first lead-out terminal 12 is separably electrically connected to arrive the power transmission of external power supply 4 with the second input terminal 20 Second source 2.

First power supply 1 includes first shell 14, the first mainboard 16 and the first battery core being electrically connected with the first mainboard 16 Group（It is not shown）, the first conducting wire group 18 is also laid in first shell 14, and the first mainboard 16 is accessed in parallel in the first conducting wire group On 18, while the first conducting wire group 18 connection first input end 10 and first lead-out terminal 12.

Second source 2 includes second shell 24, the second mainboard 26 and the second battery core being electrically connected with the second mainboard 26 Group（It is not shown）, the second conducting wire group 28 is also laid in second shell 24, and the second mainboard 26 is accessed in parallel in the second conducting wire group On 28, the second conducting wire group 28 connects the second input terminal 20 and second output terminal 22.

The sunken end face at 14 top of first shell forms the first receiving portion 19, and first lead-out terminal 12 is exposed to the first receiving 19 interior side-wall surface of portion, the bottom part with the second input terminal 20 of second shell 24 and be separably housed in first In receiving portion 19, the setting corresponding with first lead-out terminal 22 of the second input terminal 20.

24 top end surface of second shell is recessed to form the second receiving portion 29, and second output terminal 22 is exposed to the second receiving portion In 29 interior side-wall surfaces.

First input end 10 includes the positive terminal 100 and cathode on 14 end face of first shell of the first power supply 1 Terminal 102, first lead-out terminal 12 include the positive terminal on the side of the other end opposite with first input end 10 120 and negative terminal 122, respectively by first between two positive terminals 100,120 and between two negative terminals 102,122 Two conducting wires of conducting wire group 18 connect.

Second input terminal 20 includes the positive terminal 200 and cathode on 24 end face of second shell of second source 2 Terminal 202, second output terminal 22 include the positive terminal on the side of the other end opposite with the second input terminal 20 220 and negative terminal 222, respectively by second between two positive terminals 200,220 and between two negative terminals 202,222 Two conducting wires of conducting wire group 28 connect.

Third power supply 3 include third shell 34 and third mainboard 36 in third shell 34 and privates group 38 with And it is electrically connected at the third input terminal 30 in privates group 38, third mainboard 36 is parallel in privates group 38, the The side with third input terminal 30 of three shells 34 is housed in partly and separably in the second receiving portion 29, and third is defeated Enter terminal 30 to be correspondingly arranged with second output terminal 22.Third input terminal 30 includes the third shell 34 set on third power supply 3 Positive terminal 300 on bottom outside wall and negative terminal 302, positive terminal 300 and negative terminal 302 and third mainboard are just Cathode is connected by two conducting wires of privates group 38 respectively.

The storing up electricity capacity of second source 2 is less than the storing up electricity capacity of the first power supply 1.The storing up electricity capacity of third power supply 3 is less than the The storing up electricity capacity of two power supplys 2.

Due to the use of the cradle of external power supply 4, it is also equipped with leading-out terminal company corresponding with first input end 10 thereon It connects, after by the first power supply 1, second source 2 and third power supply 3, grafting is got up each other, by the first power supply 1 and external power supply 4 Connection is charged from external power supply 4 by first input end 10 to 1 input current of the first power supply, due to interior set on each right Answer the first conducting wire group 18, the second conducting wire group 28 and privates group 38 in shell through first lead-out terminal 12 and the second input terminal Son 20, second output terminal 22 are correspondingly connected with third input terminal 30, are formed complete to first the 1, second electricity of power supply The circuit that source 2 and third power supply 3 charge together, naturally it is also possible to the first power supply 1 and second source 2 are only plugged on one It rises, is charged together by external power supply 4, since the storing up electricity capacity of the first power supply 1, second source 2 and third power supply 3 is passed successively Subtract, when going out, usage scenario can be depended on, according to the electricity of estimated needs, selection carries different combinations, for example only with it One of or two even three all take, this just provide the user more facilities for selecting and using.

The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
