Can constantly it increase.Lithium battery has the advantages such as energy comparison is high, service life is long, light self-discharge rate is low.In order to reduce the external world
The influence of environment, lithium battery group would generally be placed in relatively closed environment.These use conditions can cause lithium battery group to exist
Caused substantial amounts of heat smoothly and can not be discharged quickly in the course of work, cause lithium battery temperature to steeply rise, long-time work
Make at a higher temperature, battery will to be shortened, reduce battery performance;Permanent uneven point of temperature field in battery case
Cloth by cause each lithium battery module, monomer performance it is unbalanced, and then influence the performance of whole battery system.Lithium battery is present
Security is poor, there is the danger exploded, and high/low temperature uses dangerous big.
Utility model content
A kind of the shortcomings that the purpose of this utility model is to overcome prior art to exist, there is provided simple in construction, user
Just, a kind of lithium battery explosion-proof flame-retardant structure that phenomena such as can effectively preventing lithium battery from combustion explosion occurs using process occurs.
The purpose of the utility model, is realized with the following methods：A kind of lithium battery explosion-proof flame-retardant structure, it includes shell, face
Cover, enclosure are provided with accommodating cavity, and some lithium battery packs, lithium battery pack and the electricity being arranged on mask are provided with accommodating cavity
Pole connects, it is characterised in that：Fire extinguishing layer is provided between described accommodating cavity and lithium battery pack, fire extinguishing layer is isolated including low melting point
Bag and set liquid fire retardant in the inner.
Described low melting point isolation pocket is arranged to interior empty rectangular-shaped, and lithium battery pack is placed on the inside of isolation pocket.
Described fire extinguishing layer is arranged on the side wall of accommodating cavity.
Described fire extinguishing layer is arranged on the inside of mask, between mask and lithium battery pack.
Described fire extinguishing layer is arranged between adjacent two lithium battery pack.
Described low melting point isolation pocket is fabricated by low melting point polymer.
Described liquid fire retardant is pure water.
Described liquid fire retardant is fire foam.
The beneficial effects of the utility model are：1st, simple in construction, production cost is low, improves the market competitiveness.2nd, using low
Extinguishing chemical built in fusing point isolation pocket coats lithium battery, when burn occurs in lithium battery, high temperature melt isolation pocket so that isolation
Fire retardant in bag can play a part of cooling and dilute electrolyte, prevent that lithium battery catching fire from the accident such as even exploding
Occur, the security that lifting battery uses.3rd, for the battery of different parameters, the position position of fire extinguishing layer can be accordingly adjusted, is counted
Amount etc., different places are adapted to greatest extent and are used.
Brief description of the drawings
Fig. 1 is the utility model structure sectional view.
Fig. 2 is the partial structurtes enlarged drawing of Fig. 1 in the utility model.
Fig. 3 is the second embodiment schematic diagram of fire extinguishing layer in the utility model.
Embodiment
Make specific further instruction to the utility model below in conjunction with the accompanying drawings.A kind of lithium battery explosion-proof flame-retardant structure, its
Including shell 1, mask 2, shell 1 is internally provided with accommodating cavity 3, and some lithium battery packs 4, lithium battery pack 4 are provided with accommodating cavity 3
It is connected with the electrode being arranged on mask 2, it is characterised in that：Fire extinguishing layer is provided between described accommodating cavity 3 and lithium battery pack 4
5, fire extinguishing layer 5 includes low melting point isolation pocket 51 and sets liquid fire retardant 52 in the inner.
Described low melting point isolation pocket 51 is arranged to interior empty rectangular-shaped, and lithium battery pack 4 is placed on the inside of isolation pocket.
Described fire extinguishing layer 5 is arranged on the side wall of accommodating cavity.
Described fire extinguishing layer 5 is arranged on the inside of mask 2, between mask 2 and lithium battery pack 4.
Described fire extinguishing layer 5 is arranged between adjacent two lithium battery pack 4.
Described low melting point isolation pocket 51 is fabricated by low melting point polymer.
Described liquid fire retardant 52 is pure water.
Described liquid fire retardant 52 is fire foam.
Operation principle：In this case, liquid fire retardant has been poured into layer of putting out a fire, and layer of putting out a fire is fabricated to multiple styles, will
Lithium battery pack 4 is coated in it, when lithium battery breaks down, can produce high temperature, and high temperature melts the isolation pocket 51 of low melting point,
The liquid fire retardant 52 in it is caused to leak, the liquid fire retardant 52 of leakage covers to burning-point, plays cooling fire extinguishing
And the effect of dilute electrolyte, prevent chemical reaction from continuing to produce, so as to avoid lithium battery because continuing high temperature so as to cause lithium
Battery catches fire even explodes, so as to improve the security of lithium battery.
