Abstract
The utility model discloses a battery anti-explosion device which comprises an antidetonating membrane and a pressure ring,etc. The anti-explosion device is provided between a base ring and the pressure ring. The antidetonating membrane, base ring and the pressure ring are welded into a whole which can be used as the fitting of batteries of various series, speculations and types or be welded directly with a battery shell. The welding position can be on a battery cover, a battery bottom or a shell body. The utility model can be used for batteries of various speculations.
Description
Technical field
The utility model belongs to chemical power source safety device applied technical field, particularly a kind of explosion protection for batteries.
Background technology
Present known explosion protection for batteries adopts mostly at battery shell wall or bottom mechanical indentation, or the plug pressure-relieving device.The problem of its existence is that indentation technology is subjected to multiple factor affecting such as material thickness, hardness and cutter anti-wear performance, and its repeatability, adjustable in pressure joint property are difficult to control; The problem of plug structure maximum is: because of the plug of various structures is made by macromolecular material, thereby in various media, particularly at the medium of organic solvent and hyperoxia voltinism, quicken oxidation, the degraded of high polymer easily, make its elasticity that loses original material, thereby cause final design failure.Another part of the applicant application number is: describe a kind of battery anti-explosion lid in 01277656.4 the Chinese patent application, it is that the battery cover that has insulator, pole and liquid injection hole is provided with rupture pressure disc, rupture pressure disc is provided with pressure ring, be welded as a whole by laser, the cell safety coefficient height that this Explosion-proof cap explosion-proof effect is good, make, but explosion-proof part only is suitable for using on battery cover, and therefore, the scope of application is narrow.
Summary of the invention
The utility model provides a kind of simple in structure for solving the problem that exists in the known technology, can be installed in the explosion protection for batteries on different size, each position of different model battery.
The technical scheme that the utility model is taked for the problem that exists in the solution known technology is: explosion protection for batteries partly is made up of rupture pressure disc, pressure ring etc., and described rupture pressure disc is arranged between basic ring and the pressure ring.
The utility model can also adopt following technical measures to realize: described rupture pressure disc, basic ring and pressure ring are integrally welded; Described rupture pressure disc is a metal material; Described basic ring is a metal material; Described pressure ring is a metal material.
Advantage and the good effect that the utlity model has are: the finished product after the welding both can be used as the safety device accessory of various series, all size, various size battery, again can be directly and the battery case welding, its welding position both can be located on the battery cover, also can be welded on battery bottom or the housing, so the utility model can be applicable in the battery of all size.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Please refer to accompanying drawing, according to battery product specifications and models difference, by setting the relieving pressure that needs, the material and the specification of selected rupture pressure disc 1 materials, pressure ring 3 materials and basic ring 2 materials are respectively with pressure ring 3, rupture pressure disc 1, basic ring 2 blankings, clean pressure ring 3, rupture pressure disc 1, basic ring 2, oil removing is also dry, in specific mould, presses accurately location of basic ring 2, rupture pressure disc 1, pressure ring 3 orders, by laser that pressure ring 3, rupture pressure disc 1, basic ring 2 is integrally welded, form the explosion protection for batteries of standard.
Operating principle of the present utility model is: explosion protection for batteries is installed in the battery, when battery is overcharging, to cross the cell internal pressure put, to make under the abuse conditions such as overheated or short circuit too high, when surpassing the explosion protection for batteries pressure release value of being installed, the battery anti-explosion film rupture has guaranteed the fail safe of battery.
