Abstract
The utility model relates to a battery cover board component field, and discloses a battery cover board component, and is composed of a cover board, a hollow rivet, which is in rivet connection with the cover board through the insulation piece, a flat bottom, which is in sealing connection with the rivet, as well as a bursting disk, which is welded on the flat bottom; and is characterized in that: the flat bottom is electrically connected with a metal covering, for covering the bursting disk, and is at least, provided with an air hole. The battery cover board component can be used for the battery with bursting dangers, and can decompress the battery in advance to avoid the bursting of battery.
Description
Technical field
The utility model relates to the cover plate assembly of battery, is specifically related to have the battery cover board assembly of blast resistance construction.
Background technology
During the lithium-ion electric tank discharge, be accompanied by usually and produce heat or produce gas and make its internal pressure become big, have the danger of blast on fire.In order to prevent battery explosion, explosion-protection equipment is set on battery usually.Chinese patent application CN1581533A discloses a kind of rupture pressure disc ground aluminum hull lithium ion battery that has, and the cover plate assembly of this battery adopts the next explosion-proof ground of welding rupture pressure disc ground structure mode purpose on the tubular rivet of cover plate assembly.But the battery ground rupture pressure disc with this cover plate assembly structure is exposed outside, is very easily punctured by hard thing, causes battery to scrap; Moreover it is little that this battery and external electric equipment or electric current are drawn the lead connection space, is electrically connected inconvenient.
The utility model content
The purpose of this utility model is to overcome the technological deficiency that rupture pressure disc easily breaks and inconvenience is connected with external circuit in the prior art, thereby a kind of battery cover board assembly that has the protection rupture pressure disc and be easy to the external circuit electrical connection is provided.
For achieving the above object, adopt following technical scheme: battery cover board assembly, comprise cover plate, by on the cover board tubular rivet of insulating part insulation riveted joint, be sealedly connected on the rivet flat, be welded on the rupture pressure disc on flat, it is characterized in that, be electrically connected with the metal cap that is used to cover rupture pressure disc, is provided with a pore on it at least on flat.
Further, described metal cap comprises periphery, bend and electric current lead division, and metal cap center evagination also forms a cavity between rupture pressure disc and metal cap.
Further, described pore is arranged on the bend.
Further, described metal cap is disc or straw hat shape.
Further, described rupture pressure disc is provided with indentation.
Further, also be provided with on the described battery cover board assembly and be positioned at tubular rivet kink below first pad.
Further, between first pad and kink, also be provided with second pad.
Useful technique effect of the present utility model: 1) adopted metal cap, so can protect rupture pressure disc, prevented that it from being punctured by foreign object, the electric current lead division makes things convenient for electric current to draw on the metal cap; 2) metal cap evagination formation cavity more helps the rational deformation of rupture pressure disc space, is beneficial to its pressure release of breaking under the force value of setting; 3) pore is arranged on the bend, and then pore is projected in area minimum on the rupture pressure disc, the surface of reserving for the electric current lead division is bigger, helps protecting rupture pressure disc, helps at electric current lead division projected current or welding lead; 4) indentation of rupture pressure disc can more accurate control rupture pressure disc fracture pressure value; 5) first pad can be protected insulating part to avoid kink and pierce through in making the battery cover board assembly process, and it also can be used for welding the electrode of projected current in the battery in addition; 6) second pad is used to protect first pad, prevents that bend from puncturing first pad when crooked.
