Abstract
The utility model provides a novel explosion protection cover cap for lithium batteries, which is used for the field of pressure protection devices of lithium ion power batteries. An explosion protection valve (4) is designed into a structure which covers a top cover (1); the edge of the explosion protection valve (4) is designed into a flange structure which is bended towards the center of the explosion protection valve (4) and tightly covers the edge of the top cover (1); the outer side of the top cover (1) connected with the explosion protection valve (4) is clamped with the top cover (1) through a slotted sealing ring (2) to be sealed with the explosion protection valve (4); more than one welding spots (9) is arranged on the edge covering side, and welding heads (8) are welded through tightly pressing the welding spots from top to bottom at the positions of the welding spot (9) are overlapped with the edge of the edge of the top cover (1) covered by the flange of the explosion protection valve (4). After the adoption of the technical scheme, the structure can be simplified according to the specification of the cover cap, the number of annular gaskets is reduced, and the resistance is small and stable.
Description
Technical field
The utility model relates to lithium-ion-power cell pressure protective device field, and more particularly, the utility model belongs to the explosive-proof protector block in a kind of lithium-ion-power cell pressure protective device.
Background technology
For preventing that lithium battery from rising owing to reasons such as super-charge super-discharge cause internal pressure; cause battery explosion; when making lithium-ion-power cell; install pressure protective device additional at its positive terminal---the explosive-proof protector block; this block is made up of top cover, Explosion-proof valve, dividing plate, sealing ring; wherein contain an annular gasket in the middle of Explosion-proof valve and the top cover, this annular gasket can be nickel-clad copper ring, nickel ring, aluminium ring etc.Annular gasket plays the effect of control Explosion-proof valve excessive deformation.When producing lithium-ion-power cell, require the internal resistance of battery the smaller the better, traditional handicraft is one by plastic seal ring with top cover, annular gasket, Explosion-proof valve envelope, but this structure block, the gapped existence of meeting between Explosion-proof valve, annular gasket and the top cover three, this will make resistance excessive and very unstable.Particularly resistance can rise in various degree after block being encapsulated on the battery.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of Explosion-proof valve is carried out improved lithium ion power battery explosion protection protection block; make the resistance of lithium ion power battery explosion protection protection block littler, more stable; structure is tightr; after lithium-ion-power cell was assembled into battery, resistance is no change almost.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is:
The utility model is a kind of novel lithium battery explosive-proof protector block, comprises top cover, sealing ring, annular gasket, Explosion-proof valve, dividing plate, and described Explosion-proof valve is set to the structure with the top cover parcel.
The structure that described Explosion-proof valve edge is set to flange and also closely wraps up the edge of top cover to the bending of Explosion-proof valve center.
The bending edge of described Explosion-proof valve is parallel structure with this dignity of Explosion-proof valve.
Described top cover and Explosion-proof valve contact position can keep or cancel annular gasket.
Top cover and Explosion-proof valve sealing are blocked by the sealing ring of flute profile in the outside that described top cover is connected with Explosion-proof valve.
Described top cover edge side can be provided with more than one solder joint, and Explosion-proof valve is combined more closely with top cover.
The position of described solder joint compresses the solder joint welding from top to bottom at the part soldering tip of Explosion-proof valve flange parcel top cover imbricate; Described solder joint can adopt technology welding such as electric resistance welding, stored energy welding, ratio-frequency welding or Laser Welding.
Adopt technical scheme of the present invention, according to the specification conditions of block, some specification can be saved annular gasket, and further simplified structure reduces resistance.Adopt the lithium battery explosive-proof protector block of technical solutions of the utility model, structure is tight, and reduces annular gasket, and resistance is littler and highly stable.
