Abstract
The utility model discloses a lithium-ion power battery cover, including a battery cover board, wherein fixedly connected polar posts, explosion-proof membrane and liquid injection hole body are provided on the battery cover board, the inner cavity of the liquid injection hole body is in a funnel shape, seal steel balls are provided in the inner cavity of the liquid injection hole body, spiral stops are fixed on the upper portion of the liquid injection hole body, and the explosion-proof membrane has a definite distance from the position of the liquid injection hole body on the surface of the battery cover board. The utility model can achieve the sealing to batteries under a vacuum state, no air is provide in the battery so that ballooning problem will not appear in future use.
Description
Technical field
The utility model relates to a kind of lithium-ion-power cell, relates in particular to a kind of lithium-ion-power cell lid.
Background technology
Advantages such as lithium-ion-power cell has that voltage height, electric capacity are big, light weight, operating temperature range are big, the research of high-capacity lithium-ion power battery is increasingly extensive, and successfully be used for electric bicycle, fields such as motorcycle, electric automobile.
At present, the lithium-ion-power cell lid comprises battery cover board, is installed with pole on the battery cover board, be provided with threaded liquid injection hole, fluid injection needs normal pressure to finish by hand, after fluid injection is finished, rupture pressure disc is installed below liquid injection hole, with bolt is stifled liquid injection hole is blocked then.Because lithium-ion-power cell overall dimension is bigger, existing structure can not be realized sealing of liquid injection hole under the vacuum state, and under atmospheric pressure state electrokinetic cell is sealed, and inside battery is retained air, in use occurs the bulging problem easily in the future.
The utility model content
The purpose of this utility model is just in order to overcome above-mentioned deficiency of the prior art, and a kind of lithium-ion-power cell lid of under the vacuum state battery being sealed can realized is provided.
The utility model is achieved by following technical proposals: a kind of lithium-ion-power cell lid, comprise battery cover board, battery cover board is provided with affixed pole, rupture pressure disc and fluid injection hole body, the inner chamber of described fluid injection hole body is an infundibulate, the inner chamber of described fluid injection hole body is provided with sealed steel ball, the affixed screw plug in fluid injection hole body top; Described rupture pressure disc and fluid injection hole body are provided with certain distance between the lip-deep position of battery cover board.
Affixed screw plug on the external cylindrical surface on described fluid injection hole body top.
Affixed screw plug on the inner cylinder face on described liquid injection hole intracoelomic cavity top.
Described rupture pressure disc and battery cover board welding.
The beneficial effects of the utility model are:
1, the liquid injection hole intracoelomic cavity is an infundibulate, is convenient to realize steel ball sealing;
2, fluid injection hole body top is provided with screw thread, fixes steel ball with screw plug, and sealing effectiveness is more reliable.
The utility model can be realized under the vacuum state battery being sealed, and inside battery does not have air, uses the bulging problem can not occur in the future.
Description of drawings
Fig. 1 is the utility model structural representation.
Reference numeral: 1, battery cover board, 2, pole, 3, rupture pressure disc, 4, the fluid injection hole body, 5, steel ball, 6, screw plug.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, a kind of lithium-ion-power cell lid of the utility model, comprise battery cover board 1, battery cover board 1 is provided with the affixed pole 2 of sealing, rupture pressure disc 3 and fluid injection hole body 4, the inner chamber of described fluid injection hole body 4 is an infundibulate, the inner chamber of fluid injection hole body 4 is provided with sealed steel ball 5, affixed screw plug 6 on the inner cylinder face of liquid injection hole 4 top external cylindrical surfaces or inner chamber, therefore can in vacuum tank, vacuumize battery of the present utility model is installed, after battery reaches vacuum state, realize that by frock steel ball 5 falls into the inner chamber of fluid injection hole body 4, let out vacuum then, external pressure can be pushed down steel ball 5 and realize sealing, after vacuum tank reaches condition of normal pressure, take out battery, manual fastening screw plug 6 has so just been realized under the vacuum state battery being sealed.Because rupture pressure disc is very thin, under vacuum state, it is installed in and is difficult to realize below the fluid injection hole body, therefore, need before fluid injection, it be welded on other position that is different from the liquid injection hole body position on the battery cover board.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection range of the present utility model.
Claims (4)
1. a lithium-ion-power cell lid comprises battery cover board, and battery cover board is provided with affixed pole, rupture pressure disc and fluid injection hole body, it is characterized in that, the inner chamber of described fluid injection hole body is an infundibulate, and the inner chamber of described fluid injection hole body is provided with sealed steel ball, the affixed screw plug in fluid injection hole body top; Described rupture pressure disc and fluid injection hole body are provided with certain distance between the lip-deep position of battery cover board.
