Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following specific embodiments are only
For illustrating the present invention rather than limiting the scope of the invention.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of lithium-ions battery for being not easy to reveal, including battery pack 1, shell 2, in shell
Equipped with multiple groups battery pack, it is equipped with 1 or more partition 3 in shell, battery is equipped between partition and shell or partition and partition
Group；Battery pack uses battery pack in the prior art, and primary structure includes anode, diaphragm, cathode, organic electrolyte.Using existing
There is the battery pack in technology, realizes multiple groups power supply.Automobile lithium ion battery in the prior art is multiple groups battery pack.In this reality
It applies in example, battery pack is equipped with 3 groups.
Shell is 4 blocks of side plates 21 and the integrally formed hollow structure of bottom plate 22, four blocks of side plates and bottom plate be all made of steel or
Hollow structure is made in aluminum material, battery pack is equipped in hollow structure, and be equipped with battery cover board 6, battery at the top of shell
The top of cover plate for sealing group body contact body.Battery cover board plays the role of sealing.
Side plate is equipped with multiple groups expansion-proof component 4, and expansion-proof component includes the protrusion 41 being sequentially connected and groove 42；It is adjacent prevent it is swollen
Partition is equipped between component；Expansion-proof component since rough groove and protrusion is made in side plate itself so that side plate by
When power (vibration), metastatic capacity is effectively absorbed, side plate is not easily broken, while the battery pack in side plate reduces stress, therefore electricity
Pond group is not easy stress leakage, and on the other hand, battery pack after flatulence, effectively absorbs stress since side plate also has, after flatulence
Battery pack in electrolyte be not easy leakage outflow.
The side plate of shell is connected with leakage-proof component 5, and leakage-proof component includes periphery heat sink 51, bottom sealing plate 52, periphery
Heat sink is fixedly connected with side plate, and the sealed bottom of periphery heat sink connects bottom sealing plate, and the bottom of bottom plate is pyramidal structure, bottom
Sealing ring 53 is equipped between plate and bottom sealing plate.When the battery pack of flatulence has invented leakage, due on the outer wall of side plate
Equipped with periphery heat sink, Packed bottom sealing plate is set in bottom, the electrolyte of leakage is not easy to corrode to automobile, electric vehicle.By
It is arranged to pyramidal structure in bottom, sealing ring is sealed between pyramidal structure and bottom sealing plate, realizes effective sealing, sealing effect
Fruit is very prominent, since full-size that the overall dimensions of sealing ring are sealing space makes the size of top of sealing ring be
Greater than the size of the sealing space contacted, therefore sealing effect is good, meanwhile, stress squeezes after sealing ring installation, by temperature
Degree etc. influences, and can also make sealing effect good.
In the present embodiment, 3 groups of expansion-proof components are respectively equipped on symmetrically arranged two blocks of side plates of shell.In two block lengths
Longer side plate is equipped with 3 groups of expansion-proof components, effective to absorb displacement.One piece is respectively equipped on the side plate for being equipped with expansion-proof component
The bottom of periphery heat sink, periphery heat sink is clamped bottom sealing plate.The side plate equipped with expansion-proof component is arranged in periphery heat sink
On, so that can leave, be flowed on bottom plate, then due to the bottom on floor along the groove of side plate even if being leaked after electrolyte flatulence
The bottom sealing plate of portion's sealing, effectively avoids electrolyte and leaks into outside entire battery.Micropore can be equipped on the heat sink of periphery,
After leaking, a small amount of electrolyte is leaked from micropore, and staff can have found impaired battery in time.Meanwhile in practical work
It in work, after battery drain, can not work normally, the battery of damage can also be excluded completely.
The technical means disclosed in the embodiments of the present invention is not limited only to technological means disclosed in above embodiment, further includes
Technical solution consisting of any combination of the above technical features.It should be pointed out that for those skilled in the art
