Description
[technical field]
The utility model belongs to the battery manufacturing technology field of electric motor car, particularly a kind of safe and reliable battery.
[background technology]
Electric motor car is a kind of not only laborsaving but also the vehicles efficiently, is subjected to liking very much of user.Be again a kind of vehicles of environmental protection because of electric motor car, along with the generally enhancing of social enviroment protection consciousness, electric motor car is more and more universal, and the electric motor car industry also is subjected to government department ground and supports energetically.
Also must satisfy the supporting demand in market of electric motor car as the battery of electric motor car power source, battery is electric motor car " heart ", and the performance of battery directly has influence on the performance and the quality of electric motor car, so the performance of battery is very important.
The safety valve of battery is located at loam cake middle part, and itself and loam cake are non-one-body molded.The basic element of character of safety valve comprises aluminium base pad, spring and safety-valve, has at least one air vent hole on the safety-valve, and the safety-valve below promptly links to each other with aluminium base pad by spring in battery container.In the manufacture process of battery, by on be placed on the residing opening part fluid injection of safety valve, after fluid injection is finished, aluminium base pad, spring and safety-valve are installed in order in liquid injection port.Wherein, aluminium base pad and spring have played the effect of sealing, and under normal condition, enclosure interior does not have gas, by the aluminium base pad of spring compression, makes extraneous gas, moisture etc. can't enter inside battery.When inside battery owing to discharging and recharging when producing gas, because of spring has certain modulus of elasticity, it is compressed and the jack-up that makes progress under the air pressure of regulation, thereby driving aluminium base pad moves up, the periphery of the aluminium base pad after moving leaves the ventilation space, internal gas is exitted through the air vent hole of safety-valve again by behind this space.The problem that above-mentioned safety valve exists is: at first, battery is long service time one, and spring and aluminium base pad just can wear out, thereby extraneous gas, steam can enter inside battery easily; Secondly, after spring and aluminium base pad just can wear out, when inside battery produces gas, cause gas in time to discharge, interior pressure increases, and causes housing to break, and there is the danger of blast in the battery of this moment; At last, the manufacturing process of this type of outer dress safety valve is miscellaneous, wastes time and energy.
[summary of the invention]
The utility model discloses a kind of safe and reliable battery, it has solved the above-mentioned technical problem that present battery of electric vehicle exists.
For solving the problems of the technologies described above, technical solution adopted in the utility model: a kind of safe and reliable battery, comprise housing, loam cake, housing is cuboid, housing is suitable for reading to be sealed by loam cake, the housing outer wall forms reinforcement, and the loam cake middle part forms annular groove, the loam cake middle part perforate that annular groove enclosed, this perforate and enclosure interior connect, this perforate is used for the usefulness of battery liquid-filling, and this perforate is heat-sealed after the fluid injection, and the effect of battery safety valve has been played by portion that annular groove encloses.
Described battery, annular groove is made of the arc-shaped ring groove that four roads are interrupted.
Described battery, reinforcement is laterally evenly laid with parallel form with housing upper brim edge.
The utility model improves the structure of battery safety valve, compare with present safety valve structure, it has following advantage: at first, save parts such as safety-valve, spring and aluminium base pad, safety valve and loam cake are one-body molded, both simplified the structure, do not have the problem of part aging again, safe to use; Secondly, behind a certain amount of gas of the in use inner generation of battery, safety valve breaks, gas is emitted, and the battery container fracture phenomena can not take place, and has strengthened the fail safe of battery, guarantee the security reliability in the battery use, accomplish both environmental protection, safety is relieved again; At last, safety valve and loam cake are one-body molded, need not carry out outer this one procedure of safety valve of adorning again, after fluid injection finishes, only need the liquid injection port heat-sealing is got final product, and under the prerequisite that guarantees technology, have reduced manually, have increased the convenient and swift property of technology.

Fig. 1 is the longitudinal sectional view of the utility model battery case.
Fig. 2 is the three-dimensional structure diagram of the utility model battery case.
Fig. 3 is the vertical view of the utility model battery case.
[embodiment]
Below in conjunction with accompanying drawing the utility model is elaborated.
As Figure 1-3, the housing 1 of the battery that the utility model is safe and reliable is cuboid, and it is suitable for reading by loam cake 2 sealings, and outer wall forms horizontal reinforcement 4 all around.
The middle part of loam cake 2 upwards forms one and adds fluid column 31, and the inside that adds fluid column 31 forms through hole 311, and this through hole 311 communicates with battery container inside.Form four roads mutual current interruption shape annular groove 32 in the upper cover part that adds fluid column 31 peripheries, the wall thickness of arc-shaped ring groove 32 is decided by the gas pressure that inside battery can bear, and four road arc-shaped ring grooves 32 form circles and will add in fluid column 31 is enclosed in.In the battery use, behind a certain amount of gas of its inner generation and after reaching the pressure of regulation, arc-shaped ring groove 32 is just by the air pressure inside bursting, by four effects that battery safety valve has just played in portion that road arc-shaped ring groove 32 encloses, discharge by the gas that this one in time produces enclosure interior, avoided battery to produce the phenomenon of blast.
In the battery liquid-filling process, by the inside fluid injection of the through hole that adds fluid column 31, after fluid injection finished, heat-sealing added the through hole 311 of fluid column 31.Certainly, for the terseness of structure, also can cut off after fluid injection and the heat-sealing protrude from loam cake 2 add fluid column 31.
Above-mentioned setting add fluid column 31 mainly for fluid injection and seal convenient usefulness, therefore, in structure of the present utility model, can not add fluid column 31, and directly form perforate at the annular groove middle part of loam cake 2, this perforate is used for the usefulness of fluid injection, after fluid injection finished, directly heat-sealing got final product.
