Description

Burst disk and adopt the blast resistance construction and the electrokinetic cell of this burst disk
Technical field
The present invention relates to a kind of burst disk that is used for the power battery explosion protection structure.In addition, the invention still further relates to a kind of blast resistance construction and electrokinetic cell that adopts this burst disk.
Background technology
Along with the raising of human environmental consciousness, it will be following inexorable trend that electric automobile and hybrid vehicle replace existing fuel vehicle.As the core drive energy---the power battery pack of electric automobile, it is particularly outstanding that its fail safe seems.When battery occurs can producing a large amount of gas at inside battery when unusual, cause the interior pressure of battery sharply to increase, at this moment, if a large amount of gases that produce can not get timely eliminating, battery will produce blast, causes security incident.
For fear of the generation of blast, generally blast resistance construction can be set on battery.Normally suppress trace and form simple and easy blast resistance construction on battery container, when inner pressure of battery acquired a certain degree, the impression on the battery container will be opened owing to intensity is more weak, thereby the interior pressure that discharges battery is blasted under unexpected situation to reduce battery.
Chinese patent CN2779188Y has described a kind of blast resistance construction of typically suppressing trace on housing.This kind blast resistance construction is for some little batteries, because its thickness of shell is not too thick, the processing impression can satisfy the requirement of explosion proof of battery substantially on its housing.But for electrokinetic cell, the monomer whose battery is more much bigger than our the daily battery of seeing, and the thickness of battery container is also wanted big several times.In this case, impression is difficult for processing and is difficult to the control depth of cup, thereby the reliability of explosion-proof performance also just is difficult to be guaranteed, and suppresses the safety requirements that trace can not satisfy battery simply on battery container.
Summary of the invention
Technical problem to be solved by this invention provides the burst disk that a kind of working depth that is easy to process explosion-proof impression and explosion-proof impression can accurately be controlled, and the present invention also will provide a kind of this burst disk of employing, the reliable blast resistance construction of explosion-proof performance and safe battery.
The burst disk that is used for the power battery explosion protection structure provided by the invention is formed with explosion-proof impression on the described burst disk.
Blast resistance construction provided by the invention comprises the cover plate or the exhaust port on the housing and the burst disk that is fixed on the described exhaust port that are formed at described electrokinetic cell, is formed with explosion-proof impression on this burst disk.
Electrokinetic cell provided by the invention comprises cover plate, housing and blast resistance construction, and described blast resistance construction comprises and is formed at the exhaust port on described cover plate or the housing and is fixed on burst disk on the described exhaust port, is formed with explosion-proof impression on this burst disk.
Described burst disk is fixed on the described exhaust port by the method for welding; Described burst disk be shaped as shapes such as rectangle, fillet rectangle, circle, ellipse; The L type that is shaped as of described explosion-proof impression,
Figure G200810135478XD00021
Shapes such as shape, M shape, in-line; When the material of described burst disk adopted aluminium alloy or fine aluminium, the thickness of burst disk was preferably 0.2-0.4mm, and the degree of depth of explosion-proof impression is preferably 0.01-0.03mm.
Compare with traditional blast resistance construction, the present invention adopts a burst disk that has an explosion-proof impression to replace suppressing the blast resistance construction of trace on battery container, because the processing impression is more convenient on burst disk, thereby solved the problem that on the thicker macrocell of some housings, is difficult to suppress trace, and when different batteries need satisfy different explosion-proof pressures, can in the course of processing, accurately control the working depth of impression on the burst disk, thereby can reach desirable explosion-proof effect, guarantee the reliability of explosion-proof performance of the present invention.In addition, the present invention is simple in structure, low processing cost, install more convenient, thereby can improve battery production efficient and reduce its cost.

Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
As shown in Figure 1, as one embodiment of the present invention, be processed with explosion-proof impression 2 on the burst disk 1 of the present invention, the material of the material of burst disk 1 and battery cover board 5 can be identical, for example is aluminium alloy or fine aluminium.Burst disk 1 be shaped as the fillet rectangle, thickness is 0.2-0.4mm.Being shaped as of explosion-proof impression 2
Figure G200810135478XD00031
Shape, the degree of depth of explosion-proof impression 2 are 0.01-0.03mm.In conjunction with Fig. 3 and shown in Figure 4, on the cover plate 5 of electrokinetic cell, be provided with the exhaust port 6 that is used to place burst disk 1, burst disk 1 is positioned on the exhaust port 6, adopts the method for laser or electron beam welding that it is welded, make burst disk 1 and cover plate 5 form an overall structure.When causing internal pressure to increase under battery is in abnormal conditions, the explosion-proof impression 2 among the present invention on the burst disk 1 can break in startup, inside battery air pressure is excreted out, thereby reach good explosion-proof effect, guarantees the fail safe of battery.
The present invention is not limited to above-mentioned concrete execution mode.
For example, the degree of depth of explosion-proof impression 2 can be set according to its startup needed pressure that breaks; The thickness of burst disk 1 also can be selected as the case may be, when adopting the burst disk of fine aluminium or aluminum alloy materials, can select between 0.2-0.4mm usually; The material that burst disk 1 is adopted is satisfying under the prerequisite of requirement of explosion proof, can select according to different mounting meanss, can select the metal material that is easy to weld under the welded and installed mode, can select plastics, PVC plate etc. under bonding mounting means; The shape of burst disk 1 both can be circular, also can be ellipse, rectangle, fillet rectangle or other shape; The shape of explosion-proof impression 2 can for the L type,
Figure G200810135478XD00032
Shape, M shape, in-line or other shape; In addition, burst disk 1 both can be installed on the cover plate 5 of electrokinetic cell, also can be installed on the housing of electrokinetic cell, and decide because of the position of exhaust port the installation site.
For another example, in the scope that meets the above-mentioned principle of the present invention, blast resistance construction of the present invention can also adopt down array structure: as shown in Figure 2, the material of burst disk 1 is the PVC plate, and it is shaped as circle, explosion-proof impression 2 be shaped as " L " shape.The degree of depth of explosion-proof impression is set according to the pressure that explosion-proof impression starts needs.In conjunction with Fig. 3 and shown in Figure 4, on the cover plate 5 of electrokinetic cell, be provided with the burst disk putting hole 6 that is used to place burst disk 1, burst disk 1 is positioned in the burst disk putting hole 6, it is bonding to adopt the seccotine stick to carry out, and makes burst disk 1 and cover plate 5 form an overall structure.When abnormal conditions appearred in battery, the explosion-proof impression 2 among the present invention on the burst disk 1 can in time break equally, and inside battery air pressure is excreted out.
Said structure all is an obvious mode of texturing of the present invention, all belongs to protection scope of the present invention.
