Or in the field of higher capacity, such as electric assisted bicycle, electric vehicle and household power storage device.
Assembled battery is in series by multiple cells, in current technology using cell by the use of welding piece as
Connector is welded, and this connected mode is that connector is first spoted weld to the negative pole end of battery, then the other end by connector
The positive terminal of another battery is welded to, realizes that battery is connected in series using connector, the feelings such as rosin joint, solder joint be insecure easily be present
Condition, and due to adding welding piece, cause the all-in resistance of whole module to be more than the resistance sum of each series connection pole group, especially big
In the case of current charge-discharge electricity, battery quality can be influenceed.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of assembled battery, and it can be solved
There is the problem of rosin joint, resistance is big in assembled battery in the prior art.
The purpose of this utility model is realized using following technical scheme：
A kind of assembled battery, including several cells and the battery case for accommodating the cell, the electricity
The rectangular arrangement of cell in the box of pond, each column cell form a battery pack, the top in each battery pack
The polarity of the upper end of cell is identical, and the both ends of the cell of each row are respectively positive electrode and negative electrode, the positive electricity
It is extremely described extremely towards the groove of positive electrode direction depression toward the raised circular ring in the direction away from cell, negative electricity
The outer ring of circular ring is provided with external screw thread, and the inwall of the groove is provided with the internal thread matched with external screw thread.
Preferably, the battery case is plastic box body.Plastics have insulating properties, and its hard structure can be to monomer
Battery plays more preferable protective effect, convenience in transport and storage.
Preferably, the battery case includes box body and protection cap, and the upper end of box body is provided with opening, one end of the protection cap
It is hinged with one end of opening, the other end of the other end and opening snaps connection.Pass through what is be flexibly connected between protection cap and box body
Mode, convenient to load and unload cell, even if cell use finishes, battery case can also be circulated and continued with.
Preferably, thermal grease is filled between the battery pack and the inwall of battery case, the side wall of battery case is provided with
Heat emission hole.Thermal grease and heat emission hole coordinate, and the equalized temperature contributed between each cell, prevent from sending out during use
Combustion or self-destruction phenomenon are born from, postpones the service life of assembled battery.
Preferably, cell is 18650 lithium batteries.
Preferably, the quantity of battery pack is 2.
Compared with prior art, the beneficial effects of the utility model are：
Assembled battery of the present utility model is compact-sized, and is detachably connected between cell, and connected mode will not
Cause rosin joint, situations such as solder joint is insecure occurs；And contact area is big between positive electrode and negative electrode, connection sheet is eliminated
Set so that whole battery pack resistance is significantly smaller than prior art, improves the performance of battery.

Embodiment
Below, with reference to accompanying drawing and embodiment, the utility model is described further：
As shown in figure 1, the utility model provides a kind of assembled battery, if the assembled battery in a battery case 1 by housing
A dry cell 21 is formed, and in order to provide larger electric energy, the cell 21 in battery case 1 is arranged into rectangular arranged,
Namely there is multirow to be multiplied by the cell 21 of multiple row, in the utility model, the cell 21 of each row is defined as one
Individual battery pack 2, has multiple battery packs 2 in battery case 1, in each battery pack 2, positioned at the top cell 21 it is upper
The polarity at end is all identical.The both ends of cell 21 in each row, actually namely both ends of each cell 21
Respectively positive electrode 22 and negative electrode 23, positive electrode 2 are convex, are formed toward the raised annulus in the direction away from cell 21
Shape structure, negative electrode 23 are the groove towards positive electrode direction depression.Wherein, the outer ring of circular ring is provided with external screw thread, groove
Inside be provided with the internal thread that is matched with external screw thread.When needing cell 21 being assembled into battery pack, only need to by internal thread with
External screw thread carries out screw thread mating connection so that linked into an integrated entity between adjacent cell 21, connected mode is simple and convenient, and
And operation difficulty and operating time need not be reduced by way of welding, situations such as avoiding the occurrence of rosin joint.
Cell 21 can be selected as lithium battery, specially 18650 lithium batteries, and the quantity of battery pack 2 is two, also
It is that the cell 21 in battery case 1 with two row combines, the quantity of cell 21 of each battery pack 2 is, for example, 3, but
It is to be not construed as limiting, the demand of power supply, voltage can be configured according to reality.
