Technical field
The present invention relates to power supply energy storage field, specifically a kind of lithium battery electric core protection structure.
Background technology
For the energy storage of lithium electricity and power supply industry, it is energy-accumulating medium to use LiFePO4 and ternary lithium battery, but now
The battery energy storage product that industry is done battery component is protected phenomenon be not it is fine, energy storage or power-supply device in long-distance transport or
Often occur during the vehicle-mounted use of person battery connection release with battery connection part position phenomenon of rupture, electricity occurs when serious
Pond short circuit causes equipment blast on fire, then have be exactly vehicle-mounted energy storage device either energy storage device during long-distance transport, by
In power caused by own wt and inertia energy-storage battery interior tissue can be made to change or be broken, so as to have influence on whole energy storage system
System.
Because current lithium electricity energy storage uses two kinds of batteries of LiFePO4 and ternary lithium, wherein its basis electricity of ferric phosphate lithium cell
Core is soft pack cell, and itself morphosis does not possess the functions such as stress resistance to compression.Ternary lithium cell equally has the problem of same,
And ternary lithium battery core housing is common negative pole, so ternary lithium cell and ternary lithium battery group can not all use itself
It is used as fixed or stress to use.
Therefore, it is necessary to a kind of new lithium battery electric core protection structure is provided to solve the above problems.
The content of the invention
It is an object of the invention to provide a kind of lithium battery electric core protection structure not influenceed by external force.
The present invention is achieved through the following technical solutions above-mentioned purpose：
A kind of lithium battery electric core protection structure, including battery core, the protect-ing frame structure for fixing the battery core, be set in it is described
Protection shell in protect-ing frame structure, the protect-ing frame structure include the first supporting plate, the second supporting plate, component plate and protection base,
The top of the battery core is provided with electrode copper bar, and the bottom of the electrode copper bar passes through first supporting plate and second support
Plate support, between first supporting plate and second supporting plate by the component plate connect, first supporting plate and
Second supporting plate is vertical with the discrete plate, and the component plate is located at the lower section of the electrode copper bar, the component plate
The bottom surface of top surface and the electrode copper bar support, the lower section of the battery core is provided with the protection base, on the protection base
Provided with cushion pad, the bottom of the bottom of the battery core, the bottom of first supporting plate and second supporting plate with it is described
The top contact of cushion pad, the edge of the protection base are provided with extension, the bottom of the extension and the protection shell
Contact.
Further, first supporting plate and the second supporting plate respectively be located at the battery core both sides, described first
Fagging and second supporting plate be arranged in parallel.
Further, first supporting plate, second supporting plate are formed between buffering between the protection base
Gap.
Further, the protection shell is square casing, and the side of the protection shell is provided with a plurality of of vertical direction
Reinforcement.
Compared with prior art, the beneficial effect of lithium battery electric core protection structure of the present invention is：By setting protect-ing frame structure
With protection shell, the battery core of inside can be thus allowed not avoided energy storage device or power supply by any power of outside
The basic battery core of equipment is destroyed in using transportation by any power, and either battery core internal wiring is released or is broken
Phenomenon.
Brief description of the drawings
Fig. 1 is the explosive view of the present invention.
Fig. 2 is the structural representation of battery core and protect-ing frame structure.
Embodiment
Refer to Fig. 1 to Fig. 2, lithium battery electric core protection structure, including battery core 3, the protect-ing frame structure 1 for fixing battery core 3,
