Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the block structure being applied to track type lithium battery in the present embodiment, comprises insulation shell and battery core 2; Wherein, insulation shell is snapped together by two and half shells 1 and forms, and half shell 1 is plastic material; Simultaneously with reference to figure 2, Fig. 3 and Fig. 4, half shell 1 has roof 3 and four sidewalls 4, surrounds the housing of a hollow; In the present embodiment, roof 3 is provided with three groups of first slot row parallel to each other, and be provided with second slot row between adjacent first slot row, the second slot row also arrange parallel with the first slot.
In the present embodiment, each first slot row comprise the first slot 5 of 12 track types, 12 the first slots 5 are arranged in row with the straight flange of track type for facing limit, have the first interval 6 between adjacent first slot 5, then each first slot row comprise 11 the first intervals 6.
The second slot 7,11 the second slots 7 that each second slot row comprise 11 track types are arranged in row with the straight flange of track type for facing limit, have the second interval 8 between adjacent second slot 7.
11 the second slots 7 align one by one with 11 the first intervals 6 that the first adjacent slot arranges and arrange, and the first slot 5 and the second slot 7 are staggered.
There is outer interval 9 around roof 3, make the first slot 5 and leave certain interval between the second slot 7 and sidewall 4.
The sidewall 4 of the second slot row limit end is provided with embedding nut 10; Because the second slot 7 number of each second slot row is fewer than the first slot 5 number of each first slot row, makes the second slot row shorter, therefore embedding nut 10 is arranged on the sidewall 4 of the second slot row limit end.The sidewall 4 of the first limit, interval 6 end is provided with ventilation hole 11.Sidewall 4 is provided with buckle 12, and buckle 12 comprises salient point 13 and shackle member 14; Often pair of salient point 13 and shackle member 14 lay respectively on the sidewall 4 at the first slot row two ends.
In the first slot 5 and the second slot 7, be provided with battery core 2, in the present embodiment, battery core 2 is track type battery core.
Side contrary with roof 3 on sidewall 4 is provided with location hole 15 and alignment pin 16, and when two and half shells 1 snap together, the alignment pin 16 on one and half shells 1 just inserts in the location hole 15 of another half shell 1.
In the present embodiment, the first slot 5 number of each first slot row, than many one of second slot 7 number of each second slot row, makes the second slot 7 just align one by one with the first interval 6.Also the slot number of each second slot row can be designed to, than many one of first slot 5 number of each first slot row, the first slot 5 is just alignd one by one with the second interval 8; Correspondingly embedding nut 10 is arranged on the sidewall 4 of the first slot row limit end.
Two and half shell 1 structures are identical, only need one set of die to produce, and save cost.Two and half shells 1 are in docking operation, and location hole 15 and alignment pin 16 play the effect of pre-determined bit, and then buckle 12 realizes clamping and fixes.
First slot 5 and the second slot 7 are staggered, and save space to a great extent, improve the bulk density of module; The embedding nut 10 that rear and front end is arranged for the connection in series-parallel of battery pack, particularly when several battery stacks together time, be fixed on embedding nut 10 with bolt by copper bar, the height of copper bar can not exceed insulation shell, improves the space availability ratio of module; The left and right sides is provided with multiple ventilation hole 11, meanwhile, is provided with the first interval 8, interval 6, second and outer interval 9, makes to leave gap between battery core 2 and battery core 2, realizes ventilating, and when refrigerating gas flows through battery pack, can effectively be taken away by heat.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
