Wherein: described housing comprises main casing that is connected with described lid and the bottom that is connected with described main casing.
Wherein: described main casing adopts aluminum alloy materials to make, and described lid and bottom adopt plastic material to make.
Wherein: described lid is being provided with external diameter lip suitable with described housing internal diameter and that engage with described housing with described main casing junction.
Wherein: described lid is provided with discharge switch lock, discharge socket aperture and charging socket hole.
The utlity model has following technique effect:
1. the utility model does not adopt the battery case of traditional vertical separation, and adopts the battery case that separates up and down, is fit to the little characteristics of lithium battery volume.
2. main casing of the present utility model adopts aluminium alloy to make, and improves the lithium battery heat dispersion, and lid and bottom adopt plastic cement to make, and can save cost, can improve insulation effect simultaneously.
3. the utility model lid is being provided with the interface lip of external diameter less than the housing internal diameter with the main casing junction, not only makes the easy to connect of lid and housing, and main is to avoid the protective circuit plate of lithium battery to contact with the Al-alloy metal of housing.
4. housing of the present utility model is provided with chute, makes things convenient for battery case to be installed in the electric motor car.
5. housing of the present utility model is provided with and the adaptive location notch of electric motor car installation position shape, can the self-contained battery box, prevent that battery case from rocking.

[embodiment]
Embodiment one:
As shown in Figure 1, the utility model adopts the manner of packing of separating up and down, and battery case comprises lid 1 and housing 2, and lithium battery places the cavity of their inside.Because the lithium battery volume is little, can easily it be inserted housing 2 backs and get final product with screw connection lid 1.
General electric motor car has a clamp in the position that battery is installed, and for convenience packing into of battery case, as shown in Figure 4, in the one side that housing 2 cooperates with clamp, vertical chute 23 is set.When battery is installed, the clamp in the electric motor car is slipped in the chute 23, very convenient, but also play the effect of self-contained battery box.
For self-contained battery box better, prevent that battery case from rocking, location notch 24 can be set on battery case.As shown in Figure 4, with the one side that electronic car owner's thick stick cooperates location notch 24 is set vertically at housing 2, location notch 24 can be arc, also can be other shapes, as long as adapt with the shape of electronic car owner's thick stick.
In order to improve the radiating effect of lithium battery, housing 2 employing thickness are that the aluminum alloy materials of 2mm is made; Be provided with lead, interface, switch, lithium battery protection circuit plate etc. in the lid 1, in order to guarantee insulation, lid 1 needs to adopt insulating material, makes wall thickness 3mm as the PP plastic cement.
The interface such as discharge and recharge of lithium battery is arranged on the lid 1.As shown in Figures 2 and 3, lid 1 is provided with: discharge switch lock 11, and this switch is controlled with key, when the time spent does not disconnect the battery power discharge loop; Discharge socket aperture 12, this hole are used for placing the discharge socket, and this socket is the three joints discharge socket of standard; Charging socket hole 13, this hole is used to place charging socket.
