Description
Technical field
The present invention is related to a kind of battery of electric vehicle tank shell, is arranged in particular to one kind on electric car with accommodating
The battery tank shell for having radiating and discharge structure concurrently of battery component.
Background technology
Global oil price goes up, and environmental consciousness comes back, and electric car industry development is that the whole world is attracted attention focus, wherein again with lightweight
Subject under discussion attracts most attention, and especially battery of electric vehicle module housing technology trends will be towards lightweight, quick manufacture and easily integration
And have the directions such as security concurrently and develop.Domestic development lightweight battery tank shell project to be overcome is mainly:1. shell structure is strong
(rigid demand) problem of spending：Battery tank shell is equipped on vehicle, must meet car body collision safety Design；2. radiating/runner
(life-span) problem of design：The control of battery case case temperature can determine the service life of battery；3. lightweight/manufacturing (carries
Rise) problem：Battery light-weight design, lifting weight energy density, increase endurance；Fatigue/waterproof etc. 4. (regulation) problem：Shell
Body must meet long-term use of (fatigue) and functional requirements such as (waterproofs) of paddling.
However, the battery case that general electric automobiles use（Such as electrokinetic cell）, it is no lack of to radiate for consideration person.Such as figure
Shown in 1, the Chinese U patents of CN 204905316 disclose a kind of heat radiating type battery case, including casing 1, case lid 11 and radiator
12, the case lid 11 lid be connected to the casing 1, the bottom of the casing 1 is provided with opening 13, the radiator 12 correspond to the opening 13 with
The casing 1 is connected, and the radiating effect of battery case is optimized by the setting of radiator 12.But the technology is only in battery case bottom surface
The radiator 12 of fin-type is connected, and the hot-air for rising in battery case after heat radiation is heated in case top does not solve
Scheme, solution is not also provided for the waterproof aspect of battery case in addition.
The Chinese Y patents of CN 2842750 disclose a kind of Battery case for being easy to battery ventilation and heat, including top box
Body, lower box and battery box cover, the battery mounting for being used for installing battery module is provided with lower box inner bottom surface；In lower box
Bottom face is in the inclination of arching upward that middle part is high, both sides are low, and it is in the inclined inclination of arching upward that is parallel to each other that case lid top surface is then corresponding with bottom surface,
