Description
Technical field
The utility model belongs to technical field of lithium ion, particularly relates to a kind of aluminum hull power battery explosion protection cover.
Background technology
At present, characteristics such as the aluminum hull power lithium-ion battery has that volume is little, in light weight, electric weight is strong, memoryless, environmental protection are widely used in industrial production and the daily life.Existing aluminum hull power lithium-ion battery block adopts the mode that explosionproof hole is set to realize explosion-proof purpose.But the explosion-proof performance of this structure and grade can not satisfy the manufacturing production and the safe handling needs of modern product far away.And explosionproof hole phenomenon such as usually occur breaking when lug welds takes place.Therefore, this explosion-proof mode can not reach explosion-proof purpose, has reduced the performance rate of battery, has serious technological deficiency and potential safety hazard, even can cause a serious accident etc.
Summary of the invention
The utility model provides a kind of aluminum hull power battery explosion protection cover for solving the technical problem that exists in the known technology.
The purpose of this utility model provides a kind of explosion-proof security problem that solves battery, and the electrokinetic cell of assembling has that explosion-proof performance is excellent, safe class is high, the aluminum hull power battery explosion protection cover of long service life, characteristics such as applied widely.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of aluminum hull power battery explosion protection cover, be characterized in: explosion-proof cap comprises top cover, burst disk, insulation cushion and orifice plate, and top cover and burst disk, insulation cushion and orifice plate make up successively, and burst disk and orifice plate are fixed together, orifice plate is provided with explosion-proof indentation, and burst disk is provided with explosion-proof indentation.
The utility model can also adopt following technical scheme:
Described aluminum hull power battery explosion protection cover is characterized in: coat the top cover edge to upper overturning around the burst disk.
Described aluminum hull power battery explosion protection cover is characterized in: burst disk and orifice plate are that laser spot welding is fixing in succession, and number of welds is 3-12.
Described aluminum hull power battery explosion protection cover is characterized in: the explosion-proof indentation of burst disk and orifice plate is for circular, and indentation thickness is 0.04-0.8mm.
Described aluminum hull power battery explosion protection cover is characterized in: be provided with sealing ring between burst disk, insulation cushion and orifice plate and cover plate.
Advantage and the good effect that the utlity model has are:
The aluminum hull power battery explosion protection cover is owing to adopted the utility model brand-new technology scheme, compared with prior art, the orifice plate indentation directly through less, disconnects when explosion-proof fully, can not occur that orifice plate and burst disk are torn and the situation of not cutting off the power supply takes place, improve the explosion-proof performance of electrokinetic cell.The burst disk middle part is conical concave structure down, the conical surface angle of recessed portion is less, gasket thickness is big, the action displacement of diaphragm is bigger when explosion-proof, guarantee that fully orifice plate and burst disk disconnect, when having avoided the explosion-proof action of burst disk, the orifice plate burst disk is disconnected fully, exist the situation of tearing but still not cutting off the power supply to take place because displacement is less.Therefore, improve the explosion-proof performance grade of electrokinetic cell greatly.
This aluminum hull power battery cap has characteristics simple in structure, easy to use, stable performance.The electrokinetic cell of assembling has that explosion-proof performance is excellent, safe class is high, long service life, advantage such as applied widely.
Description of drawings
Fig. 1 is an aggregate erection structural representation of the present utility model.
Among the figure, 1. top cover, 2. burst disk, 3. insulation cushion, 4. sealing ring, 5. orifice plate, 6. explosion-proof indentation, 7. cover plate, 8. aluminum hull, 9. laser solder joint, 10. explosion-proof indentation.
Embodiment
For further understanding utility model content of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Consult accompanying drawing 1.
Embodiment 1
A kind of aluminum hull power battery explosion protection cover comprises top cover 1, burst disk 2, insulation cushion 3 and orifice plate 5, and top cover 1 makes up successively with burst disk 2, insulation cushion 3 and orifice plate 5, and burst disk 2 adopts laser solder joint 9 to connect with orifice plate 5 and is fixed together, and number of welds is 6.Burst disk 2 is provided with explosion-proof indentation 10, and orifice plate 5 is provided with explosion-proof indentation 6, and the explosion-proof indentation 6 of explosion-proof indentation 10 of burst disk and orifice plate is circular.The straight warp of the explosion-proof indentation 6 of orifice plate is 6mm.Indentation thickness is 0.06mm.Coat top cover 1 edge to upper overturning around the burst disk 2.7 of burst disk 2, insulation cushion 3 and orifice plate 5 and cover plates are provided with sealing ring 4.Cover plate 7 external welding electrokinetic cell aluminum hulls 8.
The concrete mounting structure and the course of processing of present embodiment: as shown in the figure, electrokinetic cell combination mounting structure comprises: top cover 1, burst disk 2, insulation cushion 3, sealing ring 4, orifice plate 5, the base is pressed in the top cover hole, the explosion-proof indentation 10 of burst disk, laser solder joint 9, the explosion-proof indentation 6 of orifice plate.Its insulation cushion 3 thickness are 0.6mm.Burst disk 2 is welded to connect assembling mode with orifice plate 5 laser spots, and number of welds is 6, and the explosion-proof indentation 6 of circular orifice is arranged on the orifice plate 6, and the straight warp of the explosion-proof indentation 6 of orifice plate is 6mm.This indentation disconnects when explosion-proof because directly through less, can not occur that orifice plate and explosion-proof diaphragm are torn and the situation generation of not cutting off the power supply, and has improved the explosion-proof performance of electrokinetic cell.Burst disk 2 middle parts are conical concave structure down, and there is circular score line 10 at place, burst disk 2 conical upper edge.Because insulation cushion thickness is big, burst disk 2 middle parts are that the conical surface angle of conical recessed portion is less, thereby the action displacement of diaphragm is bigger when explosion-proof, guarantee that fully orifice plate and rupture pressure disc sheet disconnect, when having avoided the explosion-proof action of burst disk, because the less explosion-proof diaphragm of orifice plate that can not make of displacement disconnects fully, exist the situation of tearing but still not cutting off the power supply to take place.Therefore, improve the explosion-proof performance grade of electrokinetic cell greatly.
This aluminum hull power battery cap has characteristics simple in structure, easy to use, stable performance.The power battery explosion protection performance of assembling is excellent, safe class is high, long service life, applied widely etc.
