Abstract

The utility model discloses a delay battery box of inside heat diffusion of battery package, include the battery box casing and set up the fire prevention isolation frame in the battery box casing, the fire prevention isolation frame comprises the fire prevention isolation layer of weaving the low heat conduction fire prevention material of material cladding and forming. The utility model has the advantages that: the isolation layer is used for separating each area, the isolation layer can block the influence of open fire and heat source on the peripheral module when accidents occur or the battery core spontaneously ignites in the using process, the thermal runaway of the peripheral battery can be delayed, the escape time is strived for passengers before large-area combustion or explosion occurs in the whole battery pack, and the casualty condition caused by battery accidents is reduced.

Description

Delay battery box of inside thermal diffusion of battery package

Technical Field

The utility model relates to a technical field of battery box specifically is a delay battery box of inside thermal diffusion of battery package.

Background

Most battery package inside module is closely arranged at present on the market, if accident or electric core emergence incident in the use, the spontaneous combustion condition appears in single module, and whole package can be inside diffusing whole battery package relatively fast, leads to the inside large tracts of land of battery package to burn or explode, and the time of fleing for the passenger is less this moment, and the intensity of a fire is great, appears the casualty condition easily.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a delay battery box of inside thermal diffusion of battery package to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a delay battery box of inside thermal diffusion of battery package, includes battery box casing and sets up the fire prevention isolation frame in the battery box casing, the fire prevention isolation frame comprises the fire prevention isolation layer that the low heat conduction fire prevention material of woven materials cladding formed.

Preferably, the fireproof isolation frame is of a hollow structure, and the two sides of the fireproof isolation frame are both fireproof isolation layers formed by wrapping low-heat-conduction fireproof materials with woven materials.

Preferably, the woven material is woven by using an asbestos sheath layer.

Preferably, the low-heat-conduction fireproof material is a vermiculite insulation board.

Compared with the prior art, the beneficial effects of the utility model are that: the isolation layer is used for separating each area, the isolation layer can block the influence of open fire and heat source on the peripheral module when accidents occur or the battery core spontaneously ignites in the using process, the thermal runaway of the peripheral battery can be delayed, the escape time is strived for passengers before large-area combustion or explosion occurs in the whole battery pack, and the casualty condition caused by battery accidents is reduced.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a delay battery box of inside thermal diffusion of battery package, includes battery box casing 1 and sets up fire prevention isolation frame 2 in battery box casing 1, fire prevention isolation frame 2 comprises the fire prevention isolation layer of weaving 3 cladding low heat conduction fire-proof material 4 formation of material.

Referring to fig. 2, the fire-proof isolation frame 2 is a hollow structure, and both sides of the fire-proof isolation frame are fire-proof isolation layers formed by wrapping low thermal conductive fire-proof materials 4 with woven materials 3. The woven material 3 is woven by adopting an asbestos sleeve layer. The low-heat-conduction fireproof material 4 is a vermiculite insulation board.

The utility model discloses a theory of operation is: the component 1 is a battery box shell, and the component 2 is an internal fireproof isolation layer; the fireproof layer is of a multilayer structure, the component 3 is a woven material coated component 4, and the component 4 is a low-heat-conduction fireproof material; the component 5 is air and the hollow layer reduces the heat conduction between the two woven materials.

The fire-proof isolation layer can be directly wrapped on the modules in each area to form each independent module area.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
