With existing battery pack, compare, the monocell of the battery pack of the present utility model array arrangement that assumes diamond in shape, under the prerequisite that has the battery capacity that communicates, the space taken is less, like this, can be by unnecessary space for placing other spare and accessory parts.

The tail end of described upper and lower substrate is provided with corresponding each other upper and lower Fixing clamp-seat, and circuit board is located between upper and lower Fixing clamp-seat.

With existing battery pack, compare, circuit board placement space of the present utility model is reasonable.

Between described some monocell positive poles, link together by Copper Foil between negative pole, and form a storage battery.

Described Copper Foil comprises Copper Foil body and copper foil leads, and described Copper Foil body is by between some monocell positive poles, link together between negative pole, and described copper foil leads is connected with circuit board.

With existing battery pack, compare, some monocells of battery pack of the present utility model are by Copper Foil by each anodal connection, and each negative pole connects, and good looking appearance is generous, and contact is good.

One vertical edge of the inner surface of described upper and lower substrate respectively is provided with the cloth line groove, and the end in the side of upper and lower substrate near the cloth line groove longitudinally is provided with some open slots, is provided with the perforate be complementary with copper foil leads on open slot.

With existing battery pack, compare, battery pack of the present utility model also is provided with the cloth line groove, electric wire in battery pack is all filled in the cloth line groove after connecting, and copper foil leads is connected with the electric wire in being arranged on the cloth line groove through perforate, realized more rational connected mode, guaranteed that again all kinds of electric wires can not be exposed to outside.

Described storage battery outer is arranged with some hold-down frames.

With existing battery pack, compare, battery pack of the present utility model is in the battery case of packing into the time, between itself and battery case, also is provided with hold-down frame, and this hold-down frame makes battery pack keep definitely fixing in battery case, and has played certain antihunt action.

Described hold-down frame is provided with the card arm hinged with it, and the described card arm other end is fastened in the cloth line groove, guarantees that hold-down frame does not come off.

With existing battery pack, compare, the card arm on the hold-down frame on battery pack of the present utility model, make hold-down frame without artificially firmly placing in battery case with hand rest.

Be provided with electrode contacts with the coupling place of monocell positive and negative electrode on described Copper Foil body.

With existing battery pack, compare, the Copper Foil body of battery pack of the present utility model is provided with electrode contacts, makes Copper Foil body and monocell without just directly being communicated with by welding.

The outer surface of described upper and lower substrate is provided with some projections.

With existing battery pack, compare, the projection on the upper and lower substrate of battery pack of the present utility model can make whole battery pack and battery case that a more rational assembly structure is arranged.

Also be provided with the anticreep fixture block between the adjacent putting hole of the outer surface two of described upper and lower substrate.

With existing battery pack, compare, the anticreep fixture block of battery pack of the present utility model avoids monocell to drop out from putting hole.
