Design and develop in process at electric automobile, electrokinetic cell has important impact as the power source of electric automobile to the applicability of electric automobile, and durable, the safe handling of electrokinetic cell is except outside the Pass having with electrical property itself, also relevant with the design of battery case.
Existing electric automobile is because of arrangement space deficiency, battery case design is most of is divided into multi-tank battery case, has so both been unfavorable for battery case light-weight design, is unfavorable for again reducing battery case high-low pressure wire harness quantity, thereby both increased battery case design and manufacture cost, increased again car load security risk.The battery case that is arranged on pure Minitype electric automobile exists very large security hidden trouble, particularly the dustproof and waterproof grade of battery case and performance of ventilation and heat dispersion can not meet simultaneously, insulation safety grade is low, constant intensity is not high there is fatal defect, also exists and is not easy to the shortcomings such as replacing, installation and maintenance simultaneously.As can not be effectively also solved these factors in design battery case process, the use of battery case on electric automobile will seriously be limited.
utility model content:
The utility model completes in order to solve deficiency of the prior art, the purpose of this utility model is to provide a kind of dustproof and waterproof grade and ventilation and heat problem that can effectively reduce battery case total weight, solve battery case, does not affect the comfortableness of passenger riding in the situation that of satisfied battery capacity to greatest extent completely; Mate with body platform, and installation, maintenance, convenient disassembly are easy to operate.
The utility model solves the technical scheme that its technical problem adopts:
A kind of notch cuttype battery case, a kind of notch cuttype battery case, comprises case lid and base plate, it is characterized in that: power line, collection line and the battery module of in described battery case, arranging electrokinetic cell; In described battery case, be provided with battery pack fixed head; On described case lid and the sidewall of base plate, be equipped with flange, described case lid with base plate by being connected on flange; Described case lid comprises three layers of hierarchic structure, and the height of the first ladder, the second ladder and the 3rd ladder increases progressively successively, and described case lid length direction center line is provided with a few font strip projections, is positioned on the first ladder and the second ladder.
Further, described a few font strip projections are being provided with groove near the 3rd ladder place.
Further, the groove in described a few font strip projections is higher than second-order tread.
Further, described base plate is provided with the closed sidewall corresponding with it below a few font strip projections.
Further, described closed sidewall is provided with wire harness outlet.
Further, described base plate interior is provided with battery pack fixed head.
Further, between described base plate flange and sidewall of the bottom plate, be provided with sheet reinforcement.
Further, described case lid and base plate are by the corresponding screw established on sidewall flange and use hexagon flange bolt to be connected.
The beneficial effect that the utility model produces is: the utility model can effectively reduce battery case total weight, solve dustproof and waterproof grade and the ventilation and heat problem of battery case, does not affect the comfortableness of passenger riding in the situation that of satisfied battery capacity to greatest extent completely; Mate with body platform, and installation, maintenance, convenient disassembly are easy to operate.
brief description of the drawings:
Fig. 1 is perspective view of the present utility model;
Fig. 2 is base plate inside structure schematic diagram of the present utility model;
Fig. 3 is sectional view of the present utility model.
embodiment:
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in figure mono-, the notch cuttype battery case in the utility model is used for placing batteries of electric automobile group, thus for body platform match design notch cuttype battery case.
Wherein, the battery case of integral type, integrates electrokinetic cell, battery management system, high-pressure electronic annex, has effectively reduced the weight that the design of multi-tank battery case produces, and reduces the outside number of outgoing of Battery case, and wire harness is arranged in order.In battery case, arrange power line, collection line and the battery module of electrokinetic cell.
In this example, mainly comprise case lid 1 and base plate 2 two parts, case lid 1 top is notch cuttype, and can be divided into the first ladder 1.1, the second ladder 1.2 and 1.3, three layers of ladder height of the 3rd ladder increases successively.From scheming, can find out on the centerline direction with on battery case length direction, there are strip projection 5 structures of " several " font, this raised structures extends to the 3rd ladder 1.3 from battery case one side always, and higher than the second ladder 1.2 height.End in " several " font strip projection 5 is provided with the groove parallel with base plate 2 near the 3rd ladder place, as shown in the sectional view on figure tri-, groove height is higher than the second ladder 1.2, the second ladder 1.2 is with inclined-plane excessively to the first ladder 1.1, and this notch cuttype structure can not affect the comfortableness of passenger riding completely in the situation that of satisfied battery capacity to greatest extent.
Sidewall at case lid 1 and base plate 2 all has flange, and case lid 1 and base plate 2 are by the corresponding screw 7 established on flange and use hexagon flange bolt 4 to be connected.Simultaneously, flange on base plate 2 sidewalls also has leg-of-mutton sheet reinforcement 6 between sidewall, this sheet reinforcement 6 is arranged on sidewall taking two as one group, organizes sheet reinforcement 6 more and places along sidewall surrounding at certain intervals, for firmly more fixing with the case lid 1 of battery case.
At the front end of base plate 2, be provided with " several " font sidewall matching with " several " font bar shaped raised structures 5, on this sidewall, be provided with four wire harness outlets 3, for the wire harness that connects battery pack is derived, same position outlet, arrangement convenience, outlet is orderly.
As shown in Figure 2, base plate 2 inside at battery case are provided with bar shaped reinforcement 8, bar shaped reinforcement 8 is arranged on base plate 2 by riveted joint, battery pack fixed head 9 is laterally installed above bar shaped reinforcement 8, battery module is fixed on battery pack fixed head 9, in battery case, arrange after battery module, overall weight is distributed as front light rear heavy, automobile axle load is distributed more reasonable.
Owing to adding the strong muscle 8 of bar shaped by certain width setting, below battery pack and between base plate 2, there is gap.This gap is conducive to the heat radiation of battery pack, can effectively improve the performance of ventilating of battery pack, extends battery.
The overall structure of the project organization of a kind of battery for electric automobile case of the present utility model is simple and reliable, lightweight, and integrated degree is high, can Fast Installation dismantle, dustproof and waterproof grade is high, guarantee battery case is worked stable, safe and reliable in car load environment, reduces design and production cost.
Above-mentionedly only the concrete enforcement in the utility model is illustrated; but can not serve as unique foundation of protection range of the present utility model; every equivalence of making according to the design spirit in the utility model changes or modifies, and all should think and fall into protection range of the present utility model.
