Abstract
The utility model provides a split anti-explosion valve of a battery, which adopts a detachable structure to prolong the repeated service life of the battery and comprises a valve body arranged in the outer wall of a battery shell body and a liquid injection hole arranged on the inner wall of the battery shell body, wherein a sealing ring is arranged in the battery shell body between the valve body and the liquid injection hole, the valve body is a cylinder, an installation hole is arranged on the outer side end of the valve body, a circuit hole is arranged on the inner side end of the valve body, an anti-explosion sheet is arranged between the circular hole and the installation hole, the circular hole and the installation hole are separated by the anti-explosion sheet, and the liquid injection hole is communicated with the circular hole by a through hole of the sealing ring. As the split anti-explosion valve adopts the detachable structure, the installation of the anti-explosion valve is more convenient, and the repeated service life of the battery is prolonged.
Description
Technical field
The utility model relates to technical field of lithium batteries, specifically relates to the structure of the explosion-proof valve of the electrokinetic cell on pure electric automobile and the oily electric hybrid-electric car.
Background technology
On electric automobile and hybrid vehicle, lithium ion battery has obtained using widely at present, and lithium battery in use, when short circuit occurring, overcharge, cross when abnormal conditions such as putting, it is out of control electric current to occur, internal temperature sharply rises, when reaching uniform temperature, the gas of inside battery can expand, and causes inside battery air pressure to raise, housing meeting dilatancy also can be exploded when serious.Therefore, the lithium ion battery of metal shell all is equipped with different safety anti-explosive devices, and is too high to prevent cell internal pressure, produces blast.The safety device of lithium ion battery mainly contains following two kinds of forms at present:
A kind of is on the surface of battery metal housing, and processing has the indentation of certain depth, and when inner pressure of battery was elevated to a certain degree, indentation can break automatically, and pressure discharges, to prevent that battery is because of the explosion of interior voltage rise height.This indentation explosion-protection equipment is because in its manufacturing process, the ambient pressure and the temperature difference can damage indentation, reduce the performance of anti-riot valve.
Another is on the explosionproof hole of battery metal housing cover, processes an explosion-proof valve that contains rupture pressure disc, and this explosion-proof valve can break when inner pressure of battery raises automatically, reaches the purpose that prevents the battery explosion.But, on the explosionproof hole of cover plate, process explosion-proof valve, the processing technology complexity.In the battery production process, because the influence of manufacture craft, such as: be subjected to extraneous contact, stressed, influences such as temperature, explosion-proof valve very easily comes to harm and departs from original designing requirement or leakage.
These two kinds of lithium ion battery safety devices after indentation or explosion-proof valve break, all can not recover or change again, make entire cell scrap.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency that exists in the above-mentioned technology, and a kind of battery split explosion-proof valve is provided, and adopts demountable structure, improves the repeated use life-span of battery with this.
The utility model is to solve this technical problem the technical scheme that is adopted to be, battery split explosion-proof valve, it is characterized in that: it comprises valve body that is arranged in the battery container outer wall and the liquid injection hole of opening on the battery container inwall is equipped with sealing ring in the battery container between valve body and the liquid injection hole; Described valve body is a cylinder, has installing hole on the valve body outboard end, has circular hole on the medial extremity, is provided with burst disk between circular hole and the installing hole and is separated by burst disk; Described liquid injection hole is by the through hole and the circular hole UNICOM of sealing ring.
In technique scheme, described installing hole is an inner hexagonal hole.
In technique scheme, described burst disk adopts numerically controlled lathe directly to process on valve body, is structure as a whole with valve body.
In technique scheme, described valve body pass through screw connection in battery container, the height of valve body is lower than battery container or pole surface.
In technique scheme, the outer wall of described battery container is fixedlyed connected with the outboard end of valve body by welding manner.
The utility model structure compared with prior art, its beneficial effect is, battery split explosion-proof valve adopts demountable structure, makes the easier for installation of explosion-proof valve, has prolonged the repeated use life-span of battery.
The beneficial effect of the utility model device also is:
1, be threaded simple and reliable, easy to process.
2, adopt spot welding to reinforce, guaranteed the fail safe of explosion-proof valve work more.
3, reduce difficulty of processing, enhance productivity.
4, explosion-proof valve is not subjected to the influence of processing procedure and comes to harm or leakage, has reduced liquid injection hole and has reset and seal.

Embodiment
Below in conjunction with embodiment, the utility model is further described:
As shown in Figure 1, battery split explosion-proof valve includes valve body 4 and sealing ring 2, and wherein valve body 4 is a cylinder, and be provided with external screw thread in the side, valve body 4 one bottom faces are provided with the hexagonal endoporus, and an other bottom face is provided with circular hole 6, and installing hole 8 is an inner hexagonal hole, be provided with burst disk 3 in the circular hole 6, installing hole 8 and circular hole 6 are separated, and described sealing ring 2 is installed between valve body 4 and the liquid injection hole 1, and is provided with the through hole 7 that is communicated with liquid injection hole 1 and circular hole 6 in the middle of sealing ring 2.
During making, after battery 5 fluid injections, adopt earlier a unidirectional valve to substitute explosion-proof valve and seal liquid injection hole 1, the processing of operation after carrying out then, treat that entire cell 5 has been produced after, take off unidirectional valve, the battery 5 of again sealing ring 2 being packed into screws in batteries 5 with the inner hexagon spanner that torsion control is arranged with valve body 4, pushes down sealing ring 2, fastening then whole explosion-proof valve, and with laser with valve body 4 and battery container 5 spot welding firmly with anti-loosening.
