Description
Technical field
The present invention relates to technical field of lithium ion, more particularly to a kind of battery pack case.
Background technology
With being rooted in the hearts of the people for environmentally friendly concept, pure electric automobile also must as a kind of environmental protection automobile truly
By as following development trend of automobile industry.For a long time, the development of electric automobile has been limited to battery cost height, life-span
The two short technical bottlenecks.With the innovation and improvement of technology in recent years, battery technology is developed rapidly.Electrokinetic cell
It is dynamic gradually the advanced green such as Ni-MH battery of today, cobalt acid lithium, LiMn2O4, LiFePO4 to be developed into from traditional lead accumulator
Power battery.But, although these new type power lithium batteries are greatly improved in performance, but the raising in these performances is past
Past is to be directed to battery core.On electric automobile, electrokinetic cell needs to work in the form of stack battery, and existing stack battery exists
The advantage of Novel electric core is often had a greatly reduced quality in actual use.The cycle life of such as lithium cell is 1500 times, quite
In battery core discharge and recharge completely daily, 3-5 or so service life can be reached in the ideal situation, with the use of automobile
Life-span is close.But in the use of actual electric car by the test to stack battery it finds that, the circulation of stack battery
Service life often falls sharply even lower to half when being used as monomer.Therefore, the groups of performance of battery how is improved
It is the key during Development of Electric Vehicles.
Battery pack case has important influence to the performance of battery bag as the necessary guard block of battery bag.And it is existing
The most limited strength of battery pack case, long-term use often cause to deform or rupture, corrosion resistance also has with heat conductivility
Wait to improve, it is therefore necessary to design a kind of novel battery incrustation for the intensity requirement that can meet battery bag use condition.
The content of the invention
It is an object of the invention to provide a kind of battery pack case, by using fibre reinforced unsaturated-resin and glass
Magnesium alloy composite and fibre reinforced titanium bag aluminum-magnesium alloy composite materials that fibrous composite is covered, make battery bag

Energy.
To achieve the above object, the present invention provides a kind of battery pack case, including：Battery bag casing and with the battery bag
The battery bag bottom plate that casing is oppositely arranged, the material of the battery bag casing is fibre reinforced unsaturated-resin and glass fibre
The magnesium alloy composite that composite is covered, the material of the battery bag bottom plate is fibre reinforced titanium bag aluminum-magnesium alloy
Composite.
The battery bag casing is in housing shape, and the battery bag box house is provided with placement section, the battery bag casing bottom
The marginal position in face is provided with several equally distributed lug bosses.
The battery bag body side is provided with a hollow-out parts, and surrounding inwall is provided with several equally distributed connecting portions, described
Screwed hole is respectively equipped with several connecting portions.
The position of the correspondence connecting portion is respectively equipped with several through holes on the battery bag bottom plate.
The method of carbon fiber surface modification is in the preparation process of the fibre reinforced titanium bag aluminum-magnesium alloy composite materials
Vapour deposition process or liquid sodium method.
Beneficial effects of the present invention：A kind of battery pack case of the present invention, by using fibre reinforced unsaturated-resin
The magnesium alloy composite and fibre reinforced titanium bag aluminum-magnesium alloy composite materials covered with glass fiber compound material, makes
Battery pack case has enough intensity, while having preferable heat conductivility and superpower corrosion resistance, so as to improve battery
The performance of bag.
Brief description of the drawings
Below in conjunction with the accompanying drawings, it is described in detail by the embodiment to the present invention, technical scheme will be made
And other beneficial effects are apparent.
In accompanying drawing,
Fig. 1 is the structural representation of battery pack case of the present invention；
Fig. 2 is the structural representation of the battery bag bottom plate of battery pack case of the present invention；
