Embodiment
The application is described in further detail below by specific embodiment and with reference to accompanying drawing.
As shown in figure 1, the application is related to a kind of power battery module, including electrokinetic cell 1 and framework 2.Framework 2 includes
Two relative side plates 21 end plate 22 relative with two, side plate 21 and end plate 22 surround receiving space jointly.Wherein, two sides
Plate 21 is respectively positioned at the both sides of the orientation of multiple electrokinetic cells 1, and two end plates 22 are located at the row of multiple electrokinetic cells 1 respectively
The two ends of column direction, two side plates 21 and two end plates 22 are welded and fixed to form framework 2.Electrokinetic cell 1 is multiple and arranged successively
In row, the receiving space for being contained in framework 2.The inwall of framework 2 is provided with insulating barrier 3, framework 2 and electrokinetic cell 1 is not connect directly
Touch.Compared with patch dielectric film on a metal plate, insulating barrier 3 will not influence the adhesive strength with framework 2 because of high temperature, and being capable of basis
Demand flexibly controls the thickness of insulating barrier 3.Further, insulation strip 4 is additionally provided with the inwall of framework 2, the insulation strip 4 is fixed on absolutely
The surface of edge layer 3, further can separate electrokinetic cell 1 with insulating barrier 3, and effectively between control framework 2 and electrokinetic cell 1
Air distance, prevent that insulating barrier 3 is breakdown under high voltage, reduce potential safety hazard.
Compare, set on the insulating layer 3 with setting single insulation strip 4 on the insulating layer 3, or by insulation strip 4 is arranged in a crossed manner
The many insulation strips be arrangeding in parallel 4 are put, the segregation of electrokinetic cell 1 and insulating barrier 3 can be optimized, and simplify insulation strip 4
Mounting process.
As shown in Fig. 2 insulation strip 4 can be arranged on to the inwall of side plate 21, it is additionally provided between insulation strip 4 and side plate 21 absolutely
Edge layer 3.Orientation of the insulation strip 4 along multiple electrokinetic cells 1 is set, i.e. the trend of insulation strip 4 and the arrangement side of electrokinetic cell 1
To parallel, so single insulation strip 4 can be contacted with multiple electrokinetic cells 1, further between control framework 2 and electrokinetic cell 1
Air distance.According to the arrangement mode of electrokinetic cell in Fig. 11, the edge strips 4 that thoroughly do away be arranged in parallel more along horizontal line.
In order that single insulation strip 4 is contacted with many electrokinetic cells 1 as far as possible, the length of insulation strip 4 can be set to
The length of side plate 21 is identical.The length of side plate 21 is the size along the orientation of electrokinetic cell 1.
Set-up mode of the insulation strip 4 on end plate 22 is similar with side plate 21.Insulation strip 4 can be arranged in end plate 22
Wall, is additionally provided with insulating barrier 3 between insulation strip 4 and end plate 22.Length direction of the insulation strip 4 along single electrokinetic cell 1 is set, and makes position
Electrokinetic cell 1 in power battery module two ends can not be contacted directly with positioned at the insulating barrier 3 of the inwall of end plate 22, control framework 2
With the air distance between electrokinetic cell 1.
, can be by the length of insulation strip 4 in order to reduce the contact probability of electrokinetic cell 1 and the insulating barrier 3 of the inwall of end plate 22
It is set to identical with the length of end plate 22, the length of end plate 22 is the length of single electrokinetic cell 1.In fig. 1 and 2, end plate
22 and side plate 21 on insulation strip 4 be horizontal setting.
As an improvement, the thickness of insulation strip 4 can be 0.05-1cm.When insulation strip 4 thickness be less than 0.05cm, then between
It is not good every effect, unobvious is improved to the gapping effect of electrokinetic cell 1 and insulating barrier 3, while adding the difficult processing of insulation strip 4
Degree.When the thickness of insulation strip 4 is more than 1cm, because insulation strip 4 occupies more space, the energy of power battery module can be reduced
Metric density.Therefore, by the thickness control of insulation strip 4 within the above range, it is possible to ensureing electrokinetic cell 1 and insulating barrier 3
While gapping effect, the difficulty of processing of insulation strip 4 and the energy density of lifting power battery module are reduced.
On the basis of eradication edge strip 4 be arranged in parallel more, preferably adjacent two thoroughly do away with the distance between edge strip 4 for 1-4cm.It is logical
The normal height of electrokinetic cell 1 is 15-17cm, and when the distance is less than 1cm, then the insulation strip 4 used is excessive, increases processing cost,
Improvement to gapping effect will not also increase and significantly improve with the number of insulation strip 4.When the distance is more than 4cm, it can reduce
Insulation strip 4 is to electrokinetic cell 1 and the segregation of insulating barrier 3.Therefore, the control of the distance between edge strip 4 is thoroughly done away with by adjacent two to exist
In above range, it is possible to while the gapping effect of electrokinetic cell 1 and insulating barrier 3 is obviously improved, adding for insulation strip 4 is reduced
Work cost.
Further, insulating barrier 3 can be set in different ways.For example, insulating barrier 3 can be arranged on framework for split
The insulating trip of 2 inner surfaces.High-temperature insulation piece can be used, such as natural mica piece is arranged on by way of bonding in framework 2
Surface.The size and shape and framework 2 that insulating barrier 3 can also be made match, using insulating barrier 3 as being wholy set in framework 2
Inner surface.Insulating barrier 3 can also be the insulating coating for being coated on the inner surface of framework 2, for example, can be sprayed in the inner surface of framework 2
The coatings such as Teflon (PTFE), it would however also be possible to employ electrochemical process, insulating passivation layer, insulation are prepared in the inner surface of framework 2
Electrodeposited coating or insulation electrophoretic paint layer.The thickness of insulating barrier 3 can be 0.05-1mm, can play good insulation effect, simultaneously
The burr of insulated part is covered.
The material of framework 2 can use metal, and compared with thickness identical plastic plate, metallic plate has more preferable shock resistance
Intensity.The material of insulation strip 4 can use silica gel or plastics, can be provided simultaneously with insulating properties and resiliency.
It is not for limiting claim although the application is disclosed as above with preferred embodiment.Any this area skill
Art personnel can make some possible variations and modification on the premise of the application design is not departed from, therefore the application
The scope that protection domain should be defined by claim is defined.
