Abstract
The utility model provides a lithium ion battery pack. The battery pack is formed through series connection or parallel connection of a plurality of battery cells, is in a platy structure and has thickness the same as the diameter of one battery cell, wherein a protective circuit board is arranged at the top of the battery pack and is standing; supporting legs are arranged at the two bottom ends of the protective circuit board, so that a gap for a wire to pass through is formed between the bottom of the protective circuit board and the battery pack; epoxy boards are arranged on the two sides of the battery pack; a concealed space for containing conductors is arranged between the epoxy boards and the battery pack. The battery pack has the beneficial effects that the problem that the protective circuit board and the conductors occupy the thickness space can be simultaneously solved through arrangement of the standing protective circuit board structure and the concealed space; the epoxy boards are arranged on the two sides of the battery pack, each battery cell comes into contact and is connected with the adjacent battery cells and is also fixedly connected with the epoxy boards on the two sides, and after the battery pack is clamped by the epoxy boards on the two sides, the strength of the overall structure is higher.
Description
Technical field
The utility model relates to lithium ion battery.
Background technology
Lithium ion battery group is generally by series connection with or be connected in parallel and form by multiple cells.Existing battery pack for its overall construction intensity higher, the shape of battery pack is generally regular solid, and the form that the cell in battery pack converges to certain center, because the radius of battery pack is less, (each cell is subject to the extruding of more heterogeneous neighbour's cell, thereby forming mutual restriction fixes), its overall structure is stronger.Although the battery pack structural strength of this form is high, its thickness is thicker, and the occasion that is suitable for slimline battery group for some is also inapplicable.If cell is arranged to design according to current battery group structure, although can solve the problem that battery pack is thin, its overall construction intensity wretched insufficiency.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of lithium ion battery group, not only does thinlyyer, and the overall construction intensity of battery pack is high.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of lithium ion battery group, described battery pack is formed by connected in series or in parallel by some cells, and described battery pack is platy structure, and its thickness is identical with the diameter of a cell; The top of described battery pack is provided with protective circuit plate, and described protective circuit plate is stand-type, and its two ends, bottom are provided with the gap that feet makes bottom it and was formed for line between battery pack; The both sides of described battery pack are provided with epoxy plate, are provided with the concealed space for accommodating wire between described epoxy plate and battery pack.The thickness of general battery pack can take into account wire and the shared space of protective circuit plate, and the utility model is designed to protective circuit plate stand-type, and therefore its thickness is little more than the diameter of a cell, and solution protective circuit plate takies the problem of thickness space; Wire can be hidden in concealed space in addition, this concealed space can be the groove between adjacent monomer battery, groove can be used for collecting wire after being enclosed by epoxy plate, thereby solution wire takies the problem of thickness space, so the thickness minimum of the utility model battery pack only has the diameter of a cell.In addition, in order to strengthen the overall construction intensity of battery pack, be provided with epoxy plate in the both sides of battery pack, each cell is except being connected with adjacent cell contact, also be connected and fixed with the epoxy plate of both sides, battery pack is subject to after the epoxy plate clamping of both sides, and overall construction intensity is higher.
As improvement, described protective circuit plate is provided with through hole, is provided with copper post and connects between the epoxy plate of both sides, and described copper post is through the through hole of described protective circuit plate.The effect of copper post not only can lock the spacing between two epoxy plates, and can be for fixing protective circuit plate.Protective circuit plate, epoxy plate and battery pack are become one structure.
The beneficial effect that the utility model compared with prior art brought is:
Stand-type protective circuit plate structure and the setting of concealed space, can solve protective circuit plate and wire simultaneously and take the problem of thickness space.Both sides in battery pack are provided with epoxy plate, and each cell, except being connected with adjacent cell contact, is also connected and fixed with the epoxy plate of both sides, and battery pack is subject to after the epoxy plate clamping of both sides, and overall construction intensity is higher.
Accompanying drawing explanation
Fig. 1 is the utility model vertical view.
Fig. 2 is protective circuit plate and the schematic diagram that coordinates of battery pack.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of lithium ion battery group, described battery pack 1 is formed by connected in series or in parallel by some cells 2, and the present embodiment thinks that battery pack 1 that seven cells 2 series connection forms describes for example.Described battery pack 1 is platy structure, and its thickness is identical with the diameter of a cell 2.The top of described battery pack 1 is provided with protective circuit plate 3, and described protective circuit plate 3 is stand-type, and its two ends, bottom are provided with the gap 5 that feet 4 makes bottom it and was formed for line between battery pack 1; The both sides of described battery pack 1 are provided with epoxy plate 7, between described epoxy plate 7 and battery pack 1, are provided with the concealed space for accommodating wire.
The thickness of general battery pack 1 can take into account wire and the shared space of protective circuit plate 3, the utility model is designed to stand-type by protective circuit plate 3, therefore its thickness is little more than the diameter of a cell 2, and solution protective circuit plate 3 takies the problem of thickness space; Wire can be hidden in concealed space in addition, this concealed space can be the groove between adjacent monomer battery 2, groove can be used for collecting wire after being enclosed by epoxy plate 7, thereby solution wire takies the problem of thickness space, so the thickness minimum of the utility model battery pack 1 only has the diameter of a cell 2.In addition, in order to strengthen the overall construction intensity of battery pack 1, be provided with epoxy plate 7 in the both sides of battery pack 1, each cell 2 is except being connected with adjacent cell 2 contacts, also be connected and fixed with the epoxy plate 7 of both sides, battery pack 1 is subject to after epoxy plate 7 clampings of both sides, and overall construction intensity is higher.
As shown in Figure 1; described protective circuit plate 3 is provided with through hole, is provided with copper post 6 and connects between the epoxy plate 7 of both sides, and described copper post 6 is through the through hole of described protective circuit plate 3; the effect of copper post 6 not only can lock the spacing between two epoxy plates 7, and can be for fixing protective circuit plate 3.Make protective circuit plate 3, epoxy plate 7 and battery pack 1 structure that is connected in one.
