Abstract

Provided is an energy storage power supply ( 100 ). The energy storage power supply ( 100 ) includes a first housing ( 10 ), a fixing colloid, at least one first cell ( 20 ). The first housing ( 10 ) has an accommodation chamber ( 11 ) defined inside the first housing ( 10 ). The accommodation chamber ( 11 ) is provided with a positioning portion ( 12 ) at a bottom of the accommodation chamber ( 11 ). The positioning portion ( 12 ) has a positioning groove ( 121 ). The at least one first cell ( 20 ) is partially accommodated in the positioning groove. The fixing colloid is located in the positioning groove ( 121 ) and fixedly connected to the at least one cell ( 20 ) and a side wall of the positioning groove ( 121 ).

Claims (19)

1 . An energy storage power supply, comprising:

a housing comprising a first casing and a second casing, wherein the first casing and the second casing are detachably connected to each other and define a receiving chamber, and wherein the first casing has a positioning portion formed on an inner wall of the first casing and comprising a plurality of cylindrical recess holes;

a plurality of cylindrical cells arranged in the receiving chamber, each of the plurality of cylindrical cells having a first end and a second end opposite to the first end, wherein each of the plurality of cylindrical cells has comprising two electrodes located at the second end of the cylindrical cell, and wherein the first end of each of the plurality of cylindrical cells is inserted in a corresponding cylindrical recess hole of the plurality of cylindrical recess holes of the positioning portion;

a fixing member configured to fix the second end of each of the plurality of cylindrical cells, wherein the fixing member has a plurality of through holes, the plurality of through holes positionally corresponding to the electrodes of the plurality of cylindrical cells and corresponding the second ends of the plurality of cylindrical cells in one-to-one correspondence;

busbars located at the same side of the plurality of cylindrical cells and electrically connected to the two electrodes to allow the plurality of first cells to be connected in parallel and/or in series;

a panel disposed on the housing, wherein the panel is configured to display a quantity of electricity of the energy storage power supply; and

a port disposed on the panel, wherein the port is configured to connect the energy storage power supply to an electrical device or a charging device.

2 . The energy storage power supply according to claim 1 , wherein one of the two electrodes is a positive electrode, and the other one of the two electrodes is a negative electrode.

3 . The energy storage power supply according to claim 1 , wherein:

a plurality of snap-fitting posts is arranged in an array and arranged on an inner bottom wall of the first casing; and

each of the plurality of cylindrical recess holes of the positioning portion is formed by four snap-fitting posts of the plurality of snap-fitting posts, the four snap-fitting posts being arranged in two adjacent rows and two adjacent columns of the array.

4 . The energy storage power supply according to claim 1 , wherein:

a plurality of position-limiting strips is provided on an inner bottom wall of the first casing, each of the plurality of position-limiting strips comprising two serpentine side surfaces; and

the plurality of cylindrical recess holes of the positioning portion are formed between two adjacent serpentine side surfaces.

5 . The energy storage power supply according to claim 1 , wherein:

a one-piece support is disposed on an inner side wall of the first casing; and

the plurality of cylindrical recess holes of the positioning portion are positioning grooves formed on the one-piece support.

6 . The energy storage power supply according to claim 1 , wherein the fixing member comprises a split-type support, the split-type support being formed with a plurality of second positioning portions configured to fix the second end, each of the plurality of second positioning portions having a through hole through which a corresponding electrode of the two electrodes passes.

7 . The energy storage power supply according to claim 1 , wherein the positioning portion and the housing are integrally formed.
