Description

Power cell box used for electric vehicle

Technical field

The present invention relates to a kind of electric automobile member, particularly the dynamic battery box on the electric automobile.

Background technology

Because fuel-engined vehicle is to the pollution of environment and constantly climbing to a higher point of international petroleum price, each automobile production producer has all strengthened the research steps of electric automobile.As everyone knows, electric automobile is to provide power by its inner lithium battery of installing.Because the lithium battery shape differs, compound mode differs, and its combination housing also has special requirement, and the design of batteries of electric automobile box will be considered the installation of heat radiation, battery case of lithium battery and combination, the multiple factors such as versatility on various cars.At present, various public publications and there is no on the market can satisfy the above product that requires and occur.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of combined and instant, power cell box used for electric vehicle efficiently.

Technical scheme of the present invention is as follows: a kind of power cell box used for electric vehicle, comprise box body and lid, described box body be length obviously greater than the rectangular structure of height, an end of this box body Width sealing, and blind end is the single order terraced structure, has rectangular boss, the other end of described box body Width is uncovered, and at the fixing lid of open-mouth, this lid is positioned at box body, form access slot between the end face of lid and box body opening end, the shape size of this access slot adapts with described boss; One end of described box body length direction is provided with that main power source connects the hole and inductor connects the hole.

Adopt above technical scheme, main power source connects the hole and inductor connects the battery outlet that the hole is used for box body inside.The present invention is designed to length obviously greater than the rectangular structure of height with box body, and gauge is little, and compact conformation can adapt to various electric automobile assemblings, need not redesign, make floor assembly, has saved the development cost of electric automobile.One end of box body has rectangular boss, and the other end is provided with the access slot that adapts with boss, when needing to form row's battery pack like this, only needs the boss of a back box body end is stretched in the access slot of previous box body correspondence, can realize the assembly unit between the battery case.Above erection method is combined and instant, quick not only, helps changing fast battery case, and the battery case cellular construction compactness of being formed, and it is little to take up room, and highly versatile all can use on various types of electric automobiles.

End at above-mentioned box bottom Width has been arranged side by side two latches, and the hovering end of each latch exceeds the end face of box body correspondence, and the other end of described box bottom Width is provided with two positioning sleeves relative with the latch position.In the above structure, latch and boss are positioned at the same end of box body, and latch parallels with the width of box body, when forming battery pack, the latch of the box bottom in back inserts in the positioning sleeve of previous box bottom, by latch and positioning sleeve and boss and access slot joint, connect reliable, good stability on the one hand between two adjacent box bodys; On the other hand, assembly unit and convenient separation, quick between the box body.

Be out of shape in order to gain in strength, to prevent, and improve the bearing capacity of box body, be formed with reinforcement in the bottom surface of above-mentioned box body.

Have a ranking and put relative ventilation hole on the end of above-mentioned boss and lid, every row's ventilation hole is made up of equilateral triangle hole that is interspersed and del hole.Because the battery in the box body is generally cylindrical structure, upper and lower in the battery unit side by side between the two adjacent batteries forms triangular open space, like this each on the lid tri-angle-holed with battery between the triangle gap and boss on corresponding point-blank tri-angle-holed, and the shape size adapts, air flows smooth and easy from an end of box body to the other end thus, the battery heat radiation is good, dependable performance.When box body was assembled into the battery case unit, the ventilation hole of adjacent pack can guarantee that still performance of ventilating is good point-blank.

Place, four angles at above-mentioned box body end face is provided with locating piece, and this locating piece is a cylindrical structure, offers annular slot at the middle part of locating piece.Box body cooperates by hole clipping clamping corresponding on the annular slot on the locating piece and the floor, easy accessibility, connects reliably, can effectively prevent to come off.Box body is connected with the floor by four locating pieces, and steadiness is good, can not shake in the process that electric automobile is advanced.

End at above-mentioned box body length direction is provided with the cable cover, and the cross section of this cable cover is " ∪ " shape of accumbency, and the openend of cable cover and the end face of box body are fixed, and the cable cover connects hole and inductor with described main power source and connects escutcheon and go into wherein.Connect hole and inductor from main power source and connect the lead of drawing in the hole and be positioned at the cable cover, under the effect of dredging of cable cover, each conductor arrangement rationally, standard.

Beneficial effect: architecture of the present invention is simple, volume is small and exquisite, can realize the Rapid Combination of battery case, and combined and instant, quick, and is general on can various types of electric automobiles.
