Description

A kind of electrokinetic cell lodge body, electrokinetic cell bag, electric automobile

Technical field

This utility model relates to the electrokinetic cell field of electric automobile, particularly relates to a kind of electrokinetic cell lodge body, also relates to And a kind of electrokinetic cell bag including this battery lodge body and a kind of electric automobile.

Background technology

Along with people's raising to environmental protection requirement, research and the application of electric automobile increasingly come into one's own.Electronic Automobile power cell bag, as the power source of electric automobile, is the important component part of electric automobile.Electrokinetic cell bag typically by Casing and electrokinetic cell composition, electrokinetic cell is encapsulated in casing, and casing includes upper cover and under casing, and upper cover is fastened under casing On.Modern electric automobile power battery wraps in the case of meeting client's (design course continuation mileage) requirement, often wants cube little, heavy Amount is light, compact conformation, and selects the casing of cast aluminium material to have light weight in terms of material and molding, low cost, batch production Efficiency advantages of higher, therefore cast aluminium casing is the optimum selection of electric automobile power battery bag under casing, and upper cover typically uses insulation Performance is good, resistance to chemical attack, high-strength light, thermal conductivity is low, the coefficient of expansion is little, the glass steel material of length in service life.

Although cast aluminium casing is as electrokinetic cell and the primary load bearing structure of detecting and controlling system thereof, there is light weight, add Work low cost and other advantages, but owing to cast aluminium casing is die sinking molding, the flatness of its flange is the highest, and due to its size relatively Greatly, easily deform, during electric automobile during traveling, be especially more prone to deformation.So the design of its flange sealing structure Reasonability directly concern the serviceability of electric automobile and the safety in utilization of electric automobile.

It is close that existing electric automobile power battery bag cast aluminium box flange sealing structure generally arranges wall scroll on flange Strip of paper used for sealing, offers groove under casing, and sealing strip is placed in this groove, and the usual cross section of sealing strip is square-section.This knot Structure is higher to the flatness requirement of flange, is suitable for the sealing on plate muscle box flange limit, for as this flange of cast aluminium casing The bad sealing structure effect of flatness is less desirable.Bad in order to make up this " single rectangle " slot sealing arrangement sealing effectiveness Defect, some manufacturer uses the sealing means of " gluing auxiliary seal ", i.e. breaks fluid sealant between joint face, but " gluing Seal " there is certain defect, such as: 1, in turn result in sealing effectiveness bad for easy gluing inequality；2, easily overflow during gluing Go out flange, affect battery bag outward appearance；3, it is unfavorable for realizing semi-automation or automatic production line operation；4, during uncapping, The most firm owing to upper cover being pasted after gluing, cause difficulty of uncapping, waste time and energy, even destroy upper cover.

Further, since in the flange connection of existing electrokinetic cell lodge body, be fitted without between bolt and bolt Connect sheet, it is difficult to make the concentrated stress of flange at bolt be converted into the uniform stress of flange between bolt and bolt, thus The flange between bolt and bolt cannot be made to form effectively sealing, it is difficult to ensure that electrokinetic cell bag IP67 seals grade.

Therefore, how to improve the sealing effectiveness of existing battery lodge body, be those skilled in the art's skills of needing solution badly Art problem.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of electrokinetic cell lodge body, the sealing effectiveness of this casing More preferably, it is easy to accomplish electrokinetic cell bag seals grade and reaches IP67, and can omit and beat auxiliary seal adhesive process, laborsaving province Time, it is simple to semi-automatic, automatic production line operation.This utility model also provide for a kind of electrokinetic cell bag including this casing with And include the electric automobile of above-mentioned electrokinetic cell bag.

The technical scheme that this utility model solves above-mentioned technical problem is as follows: a kind of electrokinetic cell lodge body, is used for encapsulating Electrokinetic cell, including under casing and be installed on the upper cover on described under casing, unlike the prior art, described under casing had along week To the first outer rim extended, described upper cover has the second outer rim circumferentially, described first outer rim and described second outer rim Fixing connection after bonded to each other；Described casing also include being located between described first outer rim and described second outer rim that arrange and Along the circumferentially extending annular sealing strip of described first outer rim, described sealing strip is a plurality of and interval is arranged；Outside described first The circumference of the side fitted with described second outer rim of edge offers that adapt and the degree of depth with described sealing strip less than described The groove of the depth of section of sealing strip, described sealing strip is placed in described groove, and described bolt assembly is located at spaced apart institute State between sealing strip.

The beneficial effects of the utility model are: by arranging spaced apart a plurality of sealing strip, and sealing strip is all located at In the groove of under casing, form multiple-sealed barrier, add the pretension effect of bolt assembly arranged between sealing strip, can be Upper cover is compacted with under casing, and sealing effectiveness is more preferable, easily realizes electrokinetic cell bag IP67 and seals grade.

On the basis of technique scheme, this utility model can also do following improvement.

Further, during described sealing strip cross sectional shape is trapezoidal, rectangle, circle, semicircle, ellipse, half elliptic The combination of one or more.
