Abstract
The utility model provides an isolation battery box. The isolation battery box for an electric vehicle consists of a shell, an upper cover, trays and isolation supports, wherein a shell body and the upper cover form the battery box shell to form an airtight cavity; the trays are arranged in the battery box shell through the heat-insulated isolation supports so as to prevent the trays from being contacted with the shell; and the isolation supports are distributed at corners of the battery box shell. The isolation battery box for the electric vehicle can effectively avoid the generation of thermal bridge, and the heat insulation performance of the isolation battery box and the balanced temperature in the isolation battery box can be maintained easily.
Description
Technical field
The utility model relates to a kind of used for electric vehicle isolation battery case, specifically, relates to the battery case that a kind of used for electric vehicle has isolation features.
Background technology
In order to solve energy security and environmental protection pressure, electric automobile becomes the developing direction of future automobile.At present, electric automobile of the prior art forms its energy resource system with battery case loading electrokinetic cell; Usually, battery case is made by metal material.At high latitude area, summer in the winter temperature difference is large; During low temperature, electrokinetic cell power, capacity can decline to a great extent, even cause the problems such as not chargeable.For this reason, be necessary battery case is taked Insulation, to keep the suitable operational environment of electrokinetic cell.
Yet, being subjected to the impact of installation structure for power battery, the heat loss approach tends to exist a plurality of heat-conductive bridges, causes scattering and disappearing fast and the interior temperature imbalance of battery case of heat.
The utility model content
In order to solve above-mentioned prior art weak point, the utility model purpose provides a kind of battery for electric automobile case of improveing on structure, to overcome defective of the prior art.
In order to solve the problem of scattering and disappearing fast of heat, the utility model provides a kind of isolation battery case, described used for electric vehicle isolation battery case is comprised of shell, loam cake, pallet and spacer leg, described housing and described loam cake form the battery case shell to form airtight cavity, described pallet is installed in the described battery case shell so that described pallet does not come in contact with described battery case shell by heat insulation described spacer leg, and described spacer leg is distributed in the corner portions of described battery case shell.
According to used for electric vehicle isolation battery case of the present utility model, preferably, described cavity inner wall is coated with insulation material layer.
According to used for electric vehicle isolation battery case of the present utility model, preferably, described spacer leg and shell are bolted.
According to used for electric vehicle isolation battery case of the present utility model, preferably, described spacer leg is 4.
According to used for electric vehicle isolation battery case of the present utility model, preferably, described spacer leg is made by insulating material.
According to used for electric vehicle of the present utility model isolation battery case, preferably, the material that conductive coefficient was not more than 5W/ (mK) when described spacer leg was not higher than 350 ℃ by mean temperature is made.
According to used for electric vehicle isolation battery case of the present utility model, preferably, described battery case shell uses metal material to make.
According to used for electric vehicle isolation battery case of the present utility model, preferably, described used for electric vehicle isolation battery case also comprises electrokinetic cell, and described electrokinetic cell is installed on the described pallet, and described electrokinetic cell does not come in contact with described housing and keeps insulation distance with described housing.
Isolate battery case by the used for electric vehicle that the utility model provides, electrokinetic cell is installed in not on the pallet that comes in contact with housing, and described electrokinetic cell does not come in contact with housing, and keeps insulation distance with housing, avoid the generation of heat bridge, strengthened heat insulation effect; Use simultaneously metal material to make the battery case shell, insulating material is made spacer leg, so that battery case has the double effects of electrical isolation and heat isolation simultaneously.Used for electric vehicle isolation battery case of the present utility model can be avoided the generation of heat bridge effectively, so that battery case is easier to insulation and holding temperature is balanced.
Description of drawings
Fig. 1 is used for electric vehicle isolation battery case schematic diagram of the present utility model.
Description of reference numerals is as follows:
Housing 1, loam cake 2, pallet 3, spacer leg 4, electrokinetic cell 5.
Embodiment
In order to make the auditor can further understand structure of the present utility model, feature and other purposes, now being accompanied by accompanying drawing in conjunction with appended preferred embodiment is described in detail as follows, the illustrated embodiment of this accompanying drawing only is used for the explanation the technical solution of the utility model, and non-limiting the utility model.
As shown in Figure 1, housing 1 and the loam cake 2 common battery case shells that form form airtight cavity after the combination, and this cavity inner wall covers heat-barrier material.Pallet 3 is fixed in the battery case shell by spacer leg 4, and pallet 3 does not come in contact with the battery case shell.Spacer leg 4 is distributed in the corner portions of outer casing inner wall and is installed on the outer casing inner wall, and spacer leg 4 has heat insulating function.Electrokinetic cell 5 is installed on the pallet 3, and electrokinetic cell 5 does not come in contact with the battery case housing and keeps insulation distance with the battery case housing.Because electrokinetic cell 5 does not come in contact with housing, keeps at a distance with housing, has avoided like this generation of heat bridge, has strengthened heat insulation effect.
As shown in Figure 1, make when shell uses metal material, when spacer leg 4 was made by insulating material, battery case had the dual resisteance effect of electrical isolation and heat isolation simultaneously.
What need statement is that above-mentioned utility model content and embodiment are intended to prove the practical application of technical scheme that the utility model provides, and should not be construed as the restriction to the utility model protection range.Those skilled in the art are in spirit of the present utility model and principle, when doing various modifications, being equal to and replacing or improve.Protection range of the present utility model is as the criterion with appended claims.
