This is in order to prevent the generation of battery explosion, it is proposed that a kind of new technical scheme.
【Utility model content】
To solve problem above, the utility model proposes a kind of battery anti-explosion piece.
This battery anti-explosion piece uses following technical scheme：
A kind of battery anti-explosion piece, including the explosion-proof lamellar body of battery case is connected to, the battery case has cavity volume, described explosion-proof
Lamellar body raises up to form pressure release portion, and the pressure release portion has pressure release position；Explosion-proof lamellar body passes through the pressure release position
Axially or radially explosion, with discharge more than the pressure release position compression strength pressure.
Preferably, the inner side in the pressure release portion is connected with the cavity volume of the battery case.
Preferably, the lower surface of the explosion-proof lamellar body and the medial surface in pressure release portion are welded on the top of battery case.
Preferably, the rounded shape of explosion-proof lamellar body.
Preferably, the pressure release portion and the junction of explosion-proof lamellar body have radian, so that the smooth connection of pressure release portion is explosion-proof
Lamellar body.
The utility model beneficial effect produced compared with background technology：
The utility model employs such scheme, when the pressure inside battery case exceedes the compression strength in pressure release portion, prevents
Quick-fried sector-meeting radially or axially pops pressure release at the madial wall along pressure release portion, and protection battery or other devices will not explode,
It has simple in construction, cooperation compact, easy to use, the advantages of reasonable in design；Therefore it is that a kind of technical and economy is equal
Product with superior function.
【Brief description of the drawings】
Fig. 1 provides the explosion-proof lamellar body top view in preferred embodiment for the utility model；
Fig. 2 provides the burst disk body section structural representation in preferred embodiment for the utility model.
【Embodiment】
Embodiment of the present utility model is described below in detail, described embodiment example is shown in the drawings, wherein from beginning

, it is necessary to illustrate in description of the present utility model, for the noun of locality, if any term " " center ", " transverse direction（X）”
, " longitudinal direction（Y）", it is " vertical（Z）" " length ", " width ", " thickness ", " on ", " under ", "front", "rear", "left", "right", " perpendicular
Directly ", the indicating position such as " level ", " top ", " bottom ", " interior ", " outer ", " clockwise ", " counterclockwise " and position relationship are based on attached
Orientation or position relationship shown in figure, are for only for ease of narration the utility model and are described with simplified, rather than indicate or imply
Signified device or element must have specific orientation, be constructed and operated with particular orientation, it is impossible to be interpreted as limiting this practicality
New specific protection domain.
In addition, be only used for describing purpose if any term " first ", " second ", and it is not intended that indicating or implying relatively heavy
The property wanted or the implicit quantity for indicating technical characteristic.Thus, defining " first ", " second " feature can express or implicit include
One or more this feature, in the utility model description, " several " are meant that two or more, unless otherwise bright
It is really specific to limit.
In the utility model, except as otherwise clear stipulaties and restriction, if any term " assembling ", " connected ", " connection " term
It should go to understand as broad sense, for example, it may be being fixedly connected or being detachably connected, or be integrally connected；It can also be machine
Tool is connected；Can be joined directly together or be connected by intermediary, can be that two element internals are connected.For
For those of ordinary skill in the art, it can understand that specific in the utility model of above-mentioned term containing as the case may be
Justice.
In utility model, unless otherwise prescribed and limit, fisrt feature second feature it " on " or it " under " can be with
Directly contacted including the first and second features, it is not direct contact but by it that can also include fisrt feature and second feature
Between other characterisation contact.Moreover, fisrt feature second feature " on ", " under " and " above " include fisrt feature
