Description
Technical field
The present invention relates to a kind of battery cover boards, and in particular to easy-to-mount new energy battery cover board.
Background technology
With the development of new energy battery technology, various novel batteries oneself be widely used through starting.But it is existing novel
Battery cover board installation and removal are difficult, and short circuit is easy to happen when novel battery collides, existing novel battery cover board
It can not play the role of pressure-relief explosion-proof to novel battery, therefore we make this improvement.
Invention content
The purpose of the present invention is to provide easy-to-mount new energy battery cover boards, can effectively solve existing new energy
The problem of battery cover board installation and removal are difficult and can not play the role of pressure-relief explosion-proof to new energy battery.
The present invention is achieved through the following technical solutions：
Easy-to-mount new energy battery cover board, including cover board body are opened on the bottom surface of cover board body there are one groove,
Fix a first explosion-proof diaphragm in groove port, also opened on cover board body there are one buffer mouth, the buffer mouth in groove
Portion communicates, and is additionally provided with the second explosion-proof diaphragm, the first explosion-proof diaphragm, on the face that is contacted with inside grooves of buffer mouth
Inside grooves are surrounded explosion-proof buffering chamber by two explosion-proof diaphragms；A circle ring rib, institute are additionally provided on the bottom surface of cover board body
It states and is provided with screw thread on the outer wall of ring rib.
Preferably, the thickness of the described first explosion-proof diaphragm is 1~1.5mm.
Preferably, the thickness of the described second explosion-proof diaphragm is 1.3~2mm.
Preferably, internal diameter height of the explosion-proof buffering chamber on cover board body axis is 30~60mm.
Compared with prior art, the present invention having the following advantages and advantages：
1, the easy-to-mount new energy battery cover board of the present invention passes through the first explosion-proof diaphragm, the second explosion-proof diaphragm and recessed
The setting of slot so that explosion-proof buffering chamber is formed inside cover board, when the pressure of inside battery is excessive, the first explosion-proof diaphragm explosion,
Then explosion-proof buffering chamber increases the space of battery pressure release, plays the role of buffering pressure release, while second explosion-proof in this case
Diaphragm can play cushioning effect, avoid the problem that the directly explosion of the first explosion-proof diaphragm bursts cover board；When explosion-proof buffering chamber is insufficient
When supporting inside battery pressure release, the second explosion-proof diaphragm explosion ensures that battery directly communicates pressure release with the external world；Due to first explosion-proof
Diaphragm generates sound when bursting, people have early warning, the second explosion-proof diaphragm to be also unlikely to hurt people when bursting；
2, the easy-to-mount new energy battery cover board of the present invention, is also provided with a ring screw slot, convex annular on battery
Item is connected through a screw thread with ring screw slot, can effectively solve asking for existing new energy battery cover board installation and removal difficulty
Topic.
Description of the drawings
Attached drawing described herein is used for providing further understanding the embodiment of the present invention, constitutes one of the application
Point, do not constitute the restriction to the embodiment of the present invention.In the accompanying drawings：
Fig. 1 is schematic structural view of the invention.
Label and corresponding parts title in attached drawing：
1- cover board bodies, the first explosion-proof diaphragms of 2-, 3- buffer mouths, the second explosion-proof diaphragms of 4-, 5- explosion-proof buffering chambers, 6- annulars
Raised line.
Specific implementation mode
To make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiment and attached drawing, to this
Invention is described in further detail, and exemplary embodiment of the invention and its explanation are only used for explaining the present invention, do not make
For limitation of the invention.
Embodiment 1
As shown in Figure 1, the easy-to-mount new energy battery cover board of the present invention, including cover board body 1, in cover board body 1
It is opened on bottom surface there are one groove, a first explosion-proof diaphragm 2 is fixed in groove port, also open that there are one bufferings on cover board body 1
Mouthfuls 3, the buffer mouth 3 is communicated with inside grooves, and it is explosion-proof to be additionally provided with second on the face that is contacted with inside grooves of buffer mouth 3
Inside grooves are surrounded explosion-proof buffering chamber 5 by diaphragm 4, the first explosion-proof diaphragm 2, the second explosion-proof diaphragm 4；In cover board body 1
It is additionally provided with a circle ring rib 6 on bottom surface, screw thread is provided on the outer wall of the ring rib 6.The present invention will pass through first
The setting of explosion-proof diaphragm 2, the second explosion-proof diaphragm 4 and groove so that form explosion-proof buffering chamber 5 inside cover board, work as inside battery
Pressure it is excessive when, the first explosion-proof diaphragm 2 explosion, then explosion-proof buffering chamber 5 increases the space of battery pressure release, plays buffering and lets out
The effect of pressure, while the second explosion-proof diaphragm 4 can play cushioning effect in this case, avoid the first directly explosion of explosion-proof diaphragm 2
The problem of cover board is burst；When explosion-proof buffering chamber 5 is not enough to support inside battery pressure release, the explosion of the second explosion-proof diaphragm 4 ensures
Battery directly communicates pressure release with the external world；Due to generating sound when the first explosion-proof diaphragm 2 bursts, people have early warning, and second is explosion-proof
Diaphragm 4 is also unlikely to hurt people when bursting.A ring screw slot, ring rib 6 and ring screw slot are also provided on battery
It is connected through a screw thread, can effectively solve the problems, such as that existing new energy battery cover board installation and removal are difficult.
