Wherein, described lower cover is rectangle, and described upper casing is rectangular shape.
Wherein, described lower tops is respectively arranged with a described connection projection in left-front corner and right front angle, and position corresponding with the cell gap had in described column lithium ion battery group in the middle part of described lower cover top right side is provided with two described connection projections.
The technical scheme provided from above the utility model, compared with prior art, the utility model provides a kind of shell of column lithium ion battery group, it can ensure under the prerequisite to the security protection performance of battery pack, makes full use of gap during cylindrical battery combination, reduces the assembly structure volume of screw, save the volumetric spaces of battery pack, ensure that battery pack has high volumetric specific energy, be conducive to the wide popularization and application of Li-ion batteries piles, be of great practical significance.
Accompanying drawing explanation
The structural representation of shell when assembling Li-ion batteries piles of a kind of column lithium ion battery group that Fig. 1 provides for the utility model;
In figure: 1 is upper casing, 2 is sunk screw, and 3 is lower cover, and 4 is column lithium ion battery group, and 11 is screwing through hole, and 31 for connecting projection, and 32 is screwed hole.
Embodiment
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with drawings and embodiments, the utility model is described in further detail.
The structural representation of shell when assembling Li-ion batteries piles of a kind of column lithium ion battery group that Fig. 1 provides for the utility model.
See Fig. 1, the utility model provides a kind of shell of column lithium ion battery group, include rectangular lower cover 3, the top of described lower cover 3 is provided with column lithium ion battery group 4, described column lithium ion battery group 4 is covered with a hollow, the upper casing 1 of rectangular shape, the bottom-open of described upper casing 1, described upper casing 1 is interlocked with lower cover 3.
In the utility model, the edge at described lower cover 3 top is arranged at intervals with multiple connection projection 31, and the lateral surface of each described connection projection 31 has a screwed hole 32;
In specific implementation, described lower cover 3 top is respectively arranged with a described connection projection 31 in left-front corner and right front angle, and position corresponding with the cell gap had in described column lithium ion battery group 4 in the middle part of described lower cover 3 top right side is provided with two described connection projections 31.
When described upper casing 1 is interlocked with described lower cover 3, described upper casing 1 has multiple screwing through hole 11 on the position corresponding with described screwed hole 32, each screwing through hole 11 runs through and is provided with a sunk screw 2, and described sunk screw 2 is threaded with described screwed hole 32.
Therefore, described upper casing 1 is threaded with the described screwed hole 32 be connected on projection 31 after can being each passed through multiple described screwing through hole 11 by multiple sunk screw 2.Therefore, the structure space that screw assembling needs can be saved.
Therefore, for the shell of the column lithium ion battery group that the utility model provides, described lower cover 3 can be fastenedly connected as a whole with described upper casing 1 by described sunk screw 2, battery gap each other in column lithium ion battery group can be made full use of, by by the structural design of screwed hole at gap location, reduce space waste, simultaneously, because upper casing 1 is buckled on lower cover 3, height dimension can be reduced, the volume of remarkable reduction column lithium ion battery set product, enriches the use occasion of battery pack.
It should be noted that, for the utility model, it is placed on the combinational gap position in position in upper casing 1 and column lithium ion battery group 4 between battery according to column lithium ion battery group 4, design the position (namely connecting projection 31 and the screwed hole 32 be connected on projection 31) of lower cover 3 upper screwed hole structure, outstanding thread pore structure is made on lower cover 3 to be just in time in combinational gap place in cylindrical battery between battery, therefore, take full advantage of the inner space of column lithium ion battery group, reduce the external dimensions of shell.
In specific implementation, the battery size of the enclosure that the utility model provides is 103mm*80mm*37mm, and housing profile is of a size of 107mm*84mm*40mm, and the size of increase is outer casing thickness substantially, without extra wasting space.
