Detailed description of the invention
In the present invention, the embodiment of Battery case is as shown in Figure 1, including battery case body, battery case body includes bottom 4 and the case lid 1 being sealingly disposed in bottom 4, case lid 1 includes four cycle side plates that top board and upper end are connected with top board, wherein having a side plate is the swash plate 5 being obliquely installed with top board, seal on swash plate 5 and be provided with inflation inlet and pressure transducer 2, pressure transducer 2 connects controller (not shown), seal on inflation inlet and be provided with breather cheek valve 3, breather cheek valve 3 has the connecting portion being connected with swash plate 5 and the gas tube for inflation being arranged on connecting portion, the axis of gas tube be arranged in parallel with swash plate 5.
The operation principle of this Battery case is: after loading electrokinetic cell in battery case body, by breather cheek valve 3 to this internal gas being passed through certain pressure of battery case, owing to breather cheek valve 3 and pressure transducer 2 are arranged for sealing with battery case body, thus without the situation that gas leakage occurs, pressure transducer 2 connects controller, can judge whether gas pressure changes and then judge whether battery case body leaks gas by the output data of controller.After later stage Battery case keeps in repair, it is possible to use car load source of the gas or external air source give Battery case insufflation gas by breather cheek valve 3, next proceed through pressure transducer 2 to judge the sealing condition of Battery case.
Use breather cheek valve, gas backstreaming can be automatically prevented from, it is to avoid gas leaks from battery case body, it is ensured that the sealing effectiveness under normality.Breather cheek valve has the connecting portion being connected with swash plate and the gas tube for inflation being arranged on connecting portion, the axis of gas tube be arranged in parallel with swash plate, so gas tube is equivalent to there is certain bending, comparing and be perpendicular to battery case body when being arranged to straight tube, this structure can avoid gas tube easily to interfere with other equipment and cause device damage.The side plate of composition case lid has one for swash plate, breather cheek valve and pressure transducer be may be contained within this swash plate, compare when being directly arranged on riser, easily interfere with other equipment and cause device damage when this mode can avoid breather cheek valve and pressure transducer to protrude from battery case body.
In other embodiments of Battery case: intake valve can not be breather cheek valve, it is also possible to be a kind of to there is rotation only switch so that the intake valve only carrying out blocking can be revolved after inflation；Pressure detecting part can also be Pressure gauge；The gas tube of breather cheek valve can also be perpendicular to the straight tube of battery case body；Intake valve can also be not provided with on inflation inlet, an object can be utilized after inflation to be blocked by inflation inlet；Inflation inlet and pressure detecting part can also be arranged on other side plates or the top board of case lid；Inflation inlet and pressure detecting part can also be arranged in bottom.
The embodiment of battery system in the present invention: battery system includes battery and loads the Battery case of battery, and the concrete structure of Battery case is identical with above-mentioned Battery case, is not described in detail in this.
