Description
[technical field]
The utility model relates to double loop double-screw bolt formula lithium ion modular battery group.
[background technology]
The many employings of modular lithium ion battery group at present discharge and recharge the single loop double purpose lead-in wire modes with mouth; Be that the battery pack outward appearance is only drawn an electrode line and a negative line; Though this lead-in wire mode can be saved some wire rods, on fail safe and convenience, but has a greatly reduced quality.Adopt single-circuit lead-in wire mode, must oneself patch when the user uses and discharge and recharge mouth, occur spark phenomenon easily, have potential safety hazard, and will pull up controller plug when charging at every turn; Need pull up charging plug again during use, plug the controller plug, using to the user makes troubles.
Simultaneously, at present modular lithium ion battery group adopts the lead-in wire mode of melt casting type more, and this lead-in wire mode need add the PUR anchor leg when production and assembly, troublesome poeration, and also colloid solidification needs the time longer, causes the production cycle to prolong.
[utility model content]
The purpose of the utility model solves the problems of the prior art exactly, proposes a kind of double loop double-screw bolt formula lithium ion battery, can improve fail safe and reliability, increases the service life.
For realizing above-mentioned purpose; The utility model provides a kind of double loop double-screw bolt formula lithium ion battery, comprise housing, power brick and loam cake, said power brick is arranged in the housing; Case top lid has loam cake, leads to separate charge circuit and discharge loop on the said power brick.
As preferably; Cover on said and have three stud bolt holes; All be inserted with double-screw bolt in three stud bolt holes, lead to electrode line, charging negative line and discharge negative line on three double-screw bolts respectively, said electrode line constitutes charge circuit with the charging negative line; Electrode line constitutes discharge loop with the discharge negative line, saved user's plug trouble in the use of charging.
As preferably, also include protection system, the negative pole end of said charge circuit is connected to protection system; The charging negative line of protection system is drawn and is connected on the double-screw bolt, adopts the charge protection system, to overcharging; Overcurrent is protected, and effectively improves Product Safety, prolongs product useful life.
As preferably, an end of said electrode line, charging negative line and discharge negative line all adopts screw tightening to be fixed in the double-screw bolt, and the other end of electrode line, charging negative line and discharge negative line all has connecting ring, and is simple in structure, assembling and use all easy to operate.
As preferably, the diameter of said charging negative line, is avoided makeing mistakes in the operating process from directly distinguishing charge-discharge end in appearance less than the diameter of discharge negative line.
The beneficial effect of the utility model: the utility model adopts three-way drawing; Form separate charge circuit and discharge loop; Do not need when the user uses oneself to patch to discharge and recharge mouth, avoided the generation of spark phenomenon in the plug process, got rid of potential safety hazard; Improve fail safe and reliability, prolonged the useful life of battery.
Characteristic of the utility model and advantage will combine accompanying drawing to be elaborated through embodiment.

Fig. 1 is the structural representation of a kind of double loop of the utility model double-screw bolt formula lithium ion battery;
Fig. 2 is the structural representation of loam cake in the double-screw bolt formula lithium ion battery of a kind of double loop of the utility model;
Fig. 3 is the structural representation of screw in the double-screw bolt formula lithium ion battery of a kind of double loop of the utility model.
[embodiment]
Consult Fig. 1,2,3, a kind of double loop double-screw bolt formula lithium ion battery comprises housing, power brick 7 and loam cake 1, and said power brick 7 is arranged in the housing, and case top lid has loam cake 1, leads to separate charge circuit and discharge loop on the said power brick 7.The lead-in wire place adopts the combining structure of double-screw bolt screw connecting ring; On loam cake 1, have three stud bolt holes 2; All be inserted with double-screw bolt 6 in three stud bolt holes 2; Lead to electrode line 9, charging negative line 10 and discharge negative line 4 on three double-screw bolts 6 respectively, said electrode line 9 constitutes charge circuit with charging negative line 10, and electrode line 9 constitutes discharge loop with discharge negative line 4.One end of said electrode line 9, charging negative line 10 and discharge negative line 4 all adopts screw 5 to tighten and is fixed in the double-screw bolt 6, and the other end of electrode line 9, charging negative line 10 and discharge negative line 4 all has connecting ring 3.After double-screw bolt 6 inserted stud bolt holes 2, the electrode line 9 that will have a connecting ring 3 and another root band lead-in wire were placed on the both sides of double-screw bolt respectively, tightened fixingly from both sides with screw 5, and charging negative line 10 is identical with electrode line 9 principles with the lead-out mode of the negative line 4 of discharging.Charge circuit, the shared electrode line 9 of discharge loop both simplified the structure, and did not influence the independent operating in two loops again.
Also include protection system 8, the negative pole end of said charge circuit is connected to protection system 8, and the charging negative line 10 of protection system 8 is drawn and is connected on the double-screw bolt 6.Because charging current is less in actual the use, so select thinner charging negative line 10 for use, the diameter of charging negative line 10 is less than the diameter of discharge negative line 4, and this design can be avoided makeing mistakes in the operating process from directly distinguishing charge-discharge end in appearance.Simultaneously, charging negative line 10 adopts little binding post, and discharge negative line 4 adopts big binding post with electrode line 9.Electrode line 9, discharge negative line 4 are directly drawn, and charging negative line 10 is drawn by the protection system 8 of battery, and protected system protection guarantees the fail safe in the battery charging process, avoid overcharging and wait the incident of injury battery to give birth to, prolongation battery useful life.
The foregoing description is the explanation to the utility model, is not the qualification to the utility model, any protection range that scheme after the utility model simple transformation is all belonged to the utility model.
