Description
Technical field:
The utility model relates to a kind of explosion-proof lithium batteries.
Background technique:
Lithium battery is since light-weight, small in size, capacitance is big, the features such as chargeable speed is fast, using and its extensively, especially
It is that application has been obtained extensively on electrical equipment even automobile.But the lithium battery of lithium battery, especially large capacity is using
During, due to overcharging, over-discharge, internal short-circuit the problems such as, the electric current that may cause inside battery is excessive, so that height can be generated
The gas of warm high pressure, this meeting is so that the internal pressure and temperature of battery are all very high, if postcritical, there may be explosions etc.
Accident, and will lead to the accidents such as fire after the outflow of the flammable and explosive substance of the inside.It is typically now by the way of explosion-proof covering board
Handled, but due to rupture pressure disc be substantially reduce its bearing capacity in such a way that portion, local buckling is set, thus
The controllability for realizing pressure-bearing, but since the production level in such cases for rupture pressure disc is more demanding, the depth of scratch with
And there is very big uncertainty in the thickness of rupture pressure disc.There is no the plans of solution to this for the prior art.
Utility model content:
The utility model provides a kind of explosion-proof lithium battery, structurally reasonable, solves problems of the prior art.
Used technical solution is the utility model to solve above-mentioned technical problem:
A kind of explosion-proof lithium battery, including cabinet are equipped with several battery packs arranged vertically, in each battery pack in cabinet
Between be equipped with gap, at the top of the box body be equipped with a cover board, between cover board and battery pack be equipped with passing away, the cover board
Bottom margin is equipped with clamping side, and the clamping checkpost is mounted in box inside；A release mechanism, the peace are equipped at the middle part of cover board
Full mechanism includes safe machine framework, and the safe machine framework is installed on cover board, is successively set from bottom to top on safe machine framework
There are cushion rubber, rupture pressure disc, fixed ring, thorn membrane module；The cushion rubber is bonded on the inner wall of safe machine framework.
Preferably, if the clamping side and cabinet are connected by bolt stem.
Preferably, the thorn membrane module includes pricker and gear needle, and described pricker one end is connected with safe machine framework, pricker
The other end is equipped with needle point, and is deep on the inside of fixed ring, is arranged towards rupture pressure disc；The gear needle is oppositely arranged with pricker, keeps off needle
One end be connected with safe machine framework, keep off needle the other end be equipped with one with rupture pressure disc bar disposed in parallel.
The utility model realizes the suitable of high pressure gas using the above structure, by gap, passing away and release mechanism
When be discharged；By setting pierce membrane module so that for pressure in cabinet control by absolute pressure value, become the position of rupture pressure disc
Shifting amount, so that even if still can be realized high pressure gas in the case where explosion-proof film thickness and not satisfactory scoring operation
The timely exclusion of body, improves whole safety.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the enlarged diagram in the portion A in Fig. 1
In figure, 1, cabinet, 2, battery pack, 3, gap, 4, cover board, 5, passing away, 6, safe machine framework, 7, cushion rubber, 8,
Rupture pressure disc, 9, fixed ring, 10, pricker, 11, gear needle, 12, needle point, 13, bar, 14, release mechanism.
Specific embodiment:
In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this reality
It is described in detail with novel.
As shown in Figs. 1-2, a kind of explosion-proof lithium battery, including cabinet 1 are equipped with several batteries arranged vertically in cabinet 1
Group 2 is equipped with gap 3 between each battery pack 2, a cover board 4 is equipped at the top of cabinet 1, between cover board 4 and battery pack 2
Equipped with passing away 5, the bottom margin of the cover board 4 is equipped with clamping side 6, and the clamping side 6 is installed on 1 inside of cabinet；It is covering
The middle part of plate 4 is equipped with a release mechanism 14, and the release mechanism 14 includes safe machine framework 6, and the safe machine framework 6 is installed on
On cover board 4, it is successively arranged cushion rubber 7, rupture pressure disc 8, fixed ring 9, thorn membrane module from bottom to top on safe machine framework 6；The glue
Circle 7 is bonded on the inner wall of safe machine framework 6.
If the clamping side 6 is connected with cabinet 1 by bolt stem.Improve whole security performance, avoid clamping it is insecure,
So that cover board 4 is with cabinet 1, there is a phenomenon where be detached from.
The thorn membrane module includes pricker 10 and gear needle 11, and described 10 one end of pricker is connected with safe machine framework 6, pricker 10
The other end be equipped with needle point 12, and be deep into the inside of fixed ring 9, be arranged towards rupture pressure disc 8；The gear needle 11 is opposite with pricker 10
One end of setting, gear needle 11 is connected with safe machine framework 6, and the other end of gear needle 11 is equipped with one and the gear disposed in parallel of rupture pressure disc 8
Bar 13.Purpose existing for pricker 10 is to push rupture pressure disc to act upwards when internal gas pressure increases, acting
After to a certain extent, even if itself is not broken, it can also be ruptured under the action of pricker 10, and keeping off needle 11 is in order to avoid thorn
Rupture pressure disc after broken splashes, and high pressure gas is discharged from the gap between gear needle 11 and pricker 10.
In use, in general, since there are rupture pressure discs, in addition between all kinds of cables, the present apparatus is in the external world
State of isolation；When overcharge, over-discharge, internal short-circuit the problems such as when, other internal pressure are excessive, in order to avoid occurrence risk,
Reach in internal pressure and squeeze after rupture pressure disc touches pricker 10, is then punctured, it is explosion-proof at this time under the blocking of gear needle 11
Film is divided into remaining two parts, high pressure gas by the rupture pressure disc 8 in gap, rupture between gap, passing away 5, cushion rubber 7,
Gap outflow system between gap, pricker 10 between fixed ring 9 and gear needle 11, to guarantee whole safety.
Above-mentioned specific embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art
For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model
It protects in range.
Place is not described in detail for the utility model, is the well-known technique of those skilled in the art of the present technique.
