Description
Technical field
The utility model relates to battery technology field, particularly relates to a kind of battery-pack exterior casing structure.
Background technology
Lithium ion battery with the feature such as cycle life, low self-discharge rate of its good fail safe, good environmental suitability, overlength not only on portable electric appts as mobile phone, Digital Video and laptop computer are used widely, in the electrical equipment such as electric bicycle, electric tool, used successively, and profile also by original regular profile to circular, special-shaped transition.
In order to obtain large capacity, no matter lithium battery or the battery of other kinds, need to form battery pack by cell.In the combination of battery pack, the shell mechanism design of battery pack is the factor that affects battery capacity.At present, due to the restriction of battery-pack exterior casing structural design, the profile of jumbo battery pack is large, has limited its application within the scope of narrow space.
Utility model content
The purpose of this utility model is for the technological deficiency existing in prior art, and the battery-pack exterior casing structure that a kind of space availability ratio is high is provided.
For realizing the technical scheme that the purpose of this utility model adopts be:
A kind of battery-pack exterior casing structure, comprises the first housing and the second housing, forms the cylinder of hollow after described the first housing and the docking of the second housing; In described the first inner walls, be provided with the first screw platform, described the first screw platform is positioned at the gap location that adjacent two cells form, and is provided with the trip bolt groove of indent on the outer wall of described the first housing relative with described the first screw platform; In described trip bolt groove, be provided with the first screw hole through described the first screw platform; With in described second inner walls of described the first screw platform relative position, be provided with the second screw platform, in described the second screw platform, be provided with second screw hole relative with described the first screw hole, with the mounting groove that is provided with indent on the outer wall of described second housing of described the second screw platform relative position, in described mounting groove, the position relative with described the second screw hole is provided with installing hole; Trip bolt is through described the first screw hole and the second screw hole, and lower end enters in described installing hole, realizes being connected of described the first housing and the second housing.
Described trip bolt groove upper end open.
Described the first screw platform and the second screw platform are semicircle, are positioned at adjacent two positions that cell is tangent.
Compared with prior art, the beneficial effects of the utility model are:
Battery-pack exterior casing structure of the present utility model takes full advantage of circular housing self inside and outside space, and space availability ratio is high, combined and instant.The in the situation that of same capability, battery pack profile is little, is conducive to the application within the scope of narrow space.And battery-pack exterior casing of the present utility model is simple in structure, processing cost is low.
Accompanying drawing explanation
Figure 1 shows that the schematic diagram of the utility model battery-pack exterior casing structure.
In figure: 1. installing hole, 2. the second housing, 3. the second screw hole, 4. the second screw platform, 5. cell, 6. trip bolt, 7. the first housing, 8. trip bolt groove, 9. the first screw platform, 10. mounting groove.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The schematic diagram of the utility model battery-pack exterior casing structure as shown in Figure 1, comprises the first housing 7 and the second housing 2, forms the cylinder of hollow after described the first housing 7 and the second housing 2 docking.On described the first housing 7 inwalls, be provided with the first screw platform 9, described the first screw platform 9 is positioned at adjacent two gap locations that cell 5 forms, and is provided with the trip bolt groove 8 of indent on the outer wall of described the first housing 7 relative with described the first screw platform 9.In described trip bolt groove 8, be provided with the first screw hole through described the first screw platform 7.With on described second housing 2 inwalls of described the first screw platform 9 relative positions, be provided with the second screw platform 4, in described the second screw platform 4, be provided with second screw hole 3 relative with described the first screw hole, with the mounting groove 10 that is provided with indent on the outer wall of described second housing 2 of described the second screw platform 4 relative positions, in described mounting groove 10, the position relative with described the second screw hole 3 is provided with installing hole 1.Trip bolt 6 is through described the first screw hole and the second screw hole 3, and lower end enters in described installing hole 1, realizes being connected of described the first housing 7 and the second housing 2.
Described the first screw platform 9 and the second screw platform 4 are semicircle, are positioned at adjacent two positions that cell 5 is tangent.
For the ease of operation, described trip bolt groove 8 upper end open, lead to the end face of the first housing 7.
When use, by tangent each cell 5 arrange to combine pack in the hollow circular cylinder being formed by the first housing and the second housing.Battery-pack exterior casing structure of the present utility model is simple in structure, low processing cost, and combined and instant, takes full advantage of the space of circular batteries group inside, for the design of circular batteries group provides a kind of space availability ratio high compound mode.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
