Description
Technical field
This utility model belongs to battery insulation protection field, specifically a kind of isolation protection structure of lithium battery group.
Background technology
At present, lithium iron phosphate dynamic battery exfactory inspection flow process is broadly divided into charge and discharge cycles volume test, air-tightness
Several big steps such as test, insulating properties test.Wherein, the test of battery bag casing insulating properties is an impact battery bag safety
One critically important step of energy.Adopt epoxy resin board to separate on technology today to insulate, epoxy resin board is that raising set of cells is exhausted
The sharp weapon of edge grade.It is now widely used in set of cells insulating protection, epoxy resin board has high dielectric property, resistance to surface leakage and resistance to
Arc resistance, can effectively stop the connection between battery and casing, substantially reduce and report to the police because of the car load that casing electric leakage causes
And safety failure.But, situation is during electric automobile during traveling now, easily causes the vibration of battery bag casing, epoxy
Resin plate easy play in vibration processes, causes battery location to change, and causes connection sheet to loosen, leads between battery and casing
Contact, causes insulation fault.
Utility model content
For solving insulation board easy play in the process of moving in battery pack box of electric automobile body now, and lead to battery and case
Body contacts, and causes the problem of insulation fault, and this utility model provides a kind of isolation protection structure of lithium battery group.
This utility model is realized by following technical proposals.
A kind of isolation protection structure of lithium battery group, if including aneroid battery, the casing of cuboid and case lid, it is characterized in that,
Box house bottom surface and surrounding side are all pasted with epoxy resin board by double coated film, and battery is close to be placed in epoxy resin board
Inner side, at least each two battery are one group, and the edge pole of every Battery pack is close to be cased with rectangular upper shield, lays above upper shield
There is securing cover plate, case lid is pressed together on above securing cover plate.
The isolation protection structure of described lithium battery group, wherein, described securing cover plate is rubber slab.
The isolation protection structure of described lithium battery group, wherein, every 6 batteries are one group, and upper shield is molded set in flakes for six
Lid.
The beneficial effects of the utility model are：1st, high dielectric property epoxy resin board, the medium such as acid and alkali resistance, salt, solvent
Corrosion, improve Battery case insulating protection grade；2nd, it is covered with double coated film, fixed effect between epoxy resin board and cabinet wall
Good, epoxy resin board will not play, it is to avoid the generation of insulation fault；3rd, processing cost is low, manufactures simple；4th, 6 electricity
Pond be a module, by six in flakes injection upper shield fix pole, increase structure stability, compact conformation, safe and reliable.
Brief description
Fig. 1 is internal structure schematic diagram of the present utility model.
Fig. 2 is overlooking the structure diagram of the present utility model.
Fig. 3 is close-up schematic view of the present utility model.
In accompanying drawing：1st, casing, 2, case lid, 3, battery, 4, epoxy resin board, 5, double coated film, 6, upper shield, 7, fixing lid
Plate.
Specific embodiment
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.
As Figure 1-3, a kind of isolation protection structure of lithium battery group, including 24 cuboid batteries 3, cuboid case
Body 1 and cover the case lid 2 on casing 1, casing 1 inner bottom surface and surrounding side are posted double coated film 5, double coated film 5 are covered with
Epoxy resin board 4, in casing 1 inner bottom surface and surrounding side, 3 point of two row of 24 batteries arranges for epoxy resin board 4 all standing,
Be close to be placed in inside epoxy resin board 4,6 batteries 3 of horizontal 3 row be divided into a module, six in flakes injection upper shield 6 tightly cover,
It is fixed on the edge pole of each module battery 3, six are molded the securing cover plate 7 being covered with quality of rubber materials above upper shield 6, case in flakes
Lid 2 is pressed together on above securing cover plate 7.
The isolation protection structure of this lithium battery group, by double coated film, 5 have good insulating performance, corrosion resistant epoxy
Resin plate 4 is fixed on Battery case 1 inner surface, can have the function of insulating protection, can prevent epoxy resin board 4 in vibration again
When play, it is to avoid the generation of insulation fault.Fixed by six poles being molded 6 adjacent six batteries 3 of upper shield in flakes simultaneously
It is nested together, makes whole cell packet module, increase the stability of its structure；In vibration, six are molded upper shield 6 and case lid in flakes
7 buffering fixations of the securing cover plate of the quality of rubber materials between 2 are so as to more compact structure, safe and reliable；Processing cost is low, raw
Produce and make simply.
