Specific embodiment
It is described in detail the battery modules of the utility model with reference to the accompanying drawings.
Referring to figs. 1 to Fig. 4, battery modules according to the present utility model include：The multiple batteries 1 stacked gradually, and each electricity
Pond 1 has the explosion-proof valve 11 for internal gas discharge；Fixed frame 2 is fixed on the top of the explosion-proof valve 11 of the multiple battery 1；
And protective plate 3, it is fixed on the downside of fixed frame 2 and opposite with the explosion-proof valve 11 of the multiple battery 1.
When there is thermal runaway in the battery 1 of the battery modules of the utility model, the 1 violent aerogenesis in inside of battery, when in battery 1
When portion's air pressure is more than the ability to bear of explosion-proof valve 11, high-temperature gas can break through explosion-proof valve 11；And protective plate 3 can stop High Temperature Gas
Body prevents high-temperature gas from directly impacting and destroying other components (such as aftermentioned cover board 7) of battery modules, avoids hot accident,
The anti-thermal runaway ability of battery modules is improved, improves the security performance of battery modules.Meanwhile fixed frame 2 can enhance protective plate 3
Structural strength, ensure protective plate 3 be fixed on always the multiple battery 1 explosion-proof valve 11 top, in addition, in protective plate 3
When being subject to thermal shock, fixed frame 2 can also provide protective plate 3 outside protection.
Specifically, the function of explosion-proof valve 11 is to carry out pressure release when 1 internal pressure of battery is excessive, prevents battery 1 because internal pressure is excessive
And it explodes.When short circuit or overcharge occurs in the battery 1 of battery modules, the electrolyte inside battery 1 can generate vigorous reaction, from
And generate substantial amounts of high-temperature gas (such as carbon monoxide, carbon dioxide etc.).Temperature when high-temperature gas goes out explosion-proof valve 11 can
Up to 600 DEG C, impact force is up to 10MPa, if the gas of high temperature and pressure is acted directly on other components of battery modules, easily
It destroys the structure of battery modules or even causes fire.And by setting fixed frame 2 and protective plate 3, so that it may obstruct high-temperature gas
Impact, avoids hot accident.
In general, existing battery pack is made of multiple battery modules, and by setting fixed frame 2 and protective plate 3, also may be used
To prevent high-temperature gas from destroying battery pack.
With reference to Fig. 3 and Fig. 4,2 downside of fixed frame has groove 21, and protective plate 3 is embedded into groove 21.It is this embedded
Mechanism can be while 3 structural strength of protective plate be enhanced, the weight and protective plate 3 that can also reduce fixed frame 2 occupy
Space.
Protective plate 3 is adhered to fixed frame 2 by structure glue.Although protective plate 3 can obstruct high-temperature gas, part heat
Amount can still be transferred to the back side of protective plate 3, and therefore, the structure glue is preferably conductive structure glue 8, can will thus be protected
The heat transfer at 3 back side of plate is transmitted to other positions to fixed frame 2, and via fixed frame 2.
Protective plate 3 is using high temperature resistant, the material of heat shock resistance, for example, protective plate 3 can be micarex, flameproof fabric, fire-proof mud
And one kind in fire prevention expanding material.Wherein, since micarex has higher structural strength, certain impact can be resisted
Power, while can also well be attached on fixed frame 2, therefore protective plate 3 is preferably micarex.
Since fixed frame 2 needs fixed protection plate 3 and bears the impact force of high-temperature gas, fixed frame 2 can be by having
The aluminium alloy or steel of higher intensity are made.Since aluminium alloy has lighter quality, preferable intensity and preferable toughness,
It is therefore preferable that fixed frame 2 is aluminium alloy.
Referring to Figures 1 and 2, the battery modules further include：Two end plates 4, respectively positioned at the multiple 1 side of arrangement of battery
To both ends；And two side plates 5, respectively positioned at the both sides of the multiple battery 1, and it is fixedly connected with two end plates 4 with solid
Fixed the multiple battery 1.Two end plates 4 and two side plates 5 form window frame structure.
Referring to Figures 1 and 2, fixed frame 2 is securable to two end plates 4.Preferably, the both ends of fixed frame 2 have bending simultaneously
Fixed to the connecting portion 22 on end plate 4.Connecting portion 22 can be fixed on end plate 4 by the modes such as being bonded, being threadedly coupled or weld, excellent
Choosing is using bonding strength height and welding simple for process.End plate 4 is usually made of aluminium alloy, so in order to reduce welding difficulty,
Fixed frame 2 is preferably aluminium alloy.
With reference to Fig. 2, the battery modules further include：Baffle assembly 6, is fixed on the top of the multiple battery 1, and by institute
Multiple batteries 1 are stated to be electrically connected.Baffle assembly 6 generally includes insulating barrier, the connection sheet being arranged on partition plate and is arranged on absolutely
Harness on edge partition plate；Connection sheet is fixedly connected with the electrode terminal of battery 1, so as to by the multiple 1 connection in series-parallel of battery.It is fixed
Frame 2 is securable to baffle assembly 6, and certainly, baffle assembly 6 exposes the explosion-proof valve 11 of the multiple battery 1, so that protective plate 3
It is directly opposite with explosion-proof valve 11.
Referring to Figures 1 and 2, the battery modules further include：Cover board 7 is fixed on the multiple battery 1 and fixed frame 2
Top.Cover board 7 is from top guard screen component 6 and battery 1, and still, cover board 7 is also most susceptible to the impact of high-temperature gas,
So it needs to set protective plate 3, to prevent that cover board 7 is destroyed.
The periphery of the battery modules can also set sealing structure, to prevent the battery 1 and partition plate group inside battery modules
6 grade components of part are corroded be subject to steam and salt gas.
