Abstract
The utility model discloses a kind of battery cases, comprising: three battery receiving cavity, three battery receiving cavity are sequentially connected；Each battery receiving cavity is provided with shell and inner casing, and the inner casing is arranged in the shell, and heat-insulated gap is provided between the shell and the inner casing and forms double-shell structure；The upper surface of the shell offers multiple ventholes, and the quantity of the venthole is set as several, and venthole is taken and is symmetrically arranged side by side, and the utility model relates to battery case technical fields.The battery case, once accident occurs for lithium battery group, moment lithium battery group out of control, which is caught fire, to be discharged with blast in top vent hole, will not because of conventional lithium battery group box moment thermal runaway and cause lid to be raised, cause secondary catch fire that entire charge position is caused to cause to catch fire more greatly and area or injure personnel, when battery when something goes wrong, double-deck shell can play the role of security protection.
Description
Technical field
The utility model relates to battery case technical field, specially a kind of battery case.
Background technique
Battery, which refers to, fills electrolyte solution and metal electrode to generate the cup of electric current, slot or other containers or clad vessel
Chemical energy can be converted to the device of electric energy by segment space.Point with anode, cathode.With the development of science and technology battery refers to
The midget plant that can be produced electricl energy.Such as solar battery.The performance parameter of battery mainly has electromotive force, capacity, specific energy and electricity
Resistance.Energy source is utilized the battery as, it is available that there is burning voltage, stabling current, long-time stable power supply, by extraneous shadow
The electric current of very little is rung, and battery structure is simple, easy to carry, charge and discharge are easy to operation, not by outside climatic and temperature
Influence, stable and reliable for performance, the performance of various aspects in modern society's life has great role.Battery case is by several lists
The stack battery of the compositions such as body battery, cabinet, battery management system and associated mounting structure part (equipment), has standard compliant
Battery box structure, battery case monitoring device, battery case connector, battery case ring control equipment etc..
Traditional lithium battery group is possible in normal course of operation can be because faulty operation causes into water, inside battery connection
Battery catches fire caused by partial short circuit, and the chest moment thermal runaway of conventional lithium battery group will lead to lid and be raised, and cause two
It is secondary to catch fire, cause the problem of catching fire area more greatly or injuring personnel, and traditional battery case is single layer designs, for driving
The safety for multiplying personnel is poor.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of battery case, and heat is lost after solving lithium battery accident
The problem of conduct causes lid to be raised, will cause more major break down.
In order to achieve the above object, the utility model is achieved by the following technical programs: a kind of battery case, comprising: three
A battery receiving cavity, three battery receiving cavity are sequentially connected；Each battery receiving cavity is provided with shell
With inner casing, the inner casing is arranged in the shell, and heat-insulated gap is provided between the shell and the inner casing and forms bivalve
Body structure；The upper surface of the shell offers multiple ventholes, and the quantity of the venthole is set as several, and ventilates
Take symmetrical be arranged side by side in hole.
Preferably, the top and bottom of the case surface side offer handle slot.
Beneficial effect
The utility model provides a kind of battery case.Have compared with prior art it is following the utility model has the advantages that
(1), the battery case is provided with shell and inner casing by battery receiving cavity, the top of case surface side and
Bottom offers handle slot, is arranged by the joint of inner casing, venthole and shell, once accident, moment occur for lithium battery group
Lithium battery group out of control, which is caught fire, to be discharged with blast in top vent hole, will not be because of the box moment thermal runaway of conventional lithium battery group
And lid is caused to be raised, cause secondary catch fire that entire charge position is caused to cause to catch fire area more greatly or injure personnel, when
When something goes wrong, double-deck shell can play the role of security protection to battery, and device entirety advantage is exactly to lose in lithium battery group
Control state can be effectively protected property and directly not cause directly to injure to personnel, will not cause more because lithium battery is on fire
The big area that catches fire.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model；
Fig. 2 is the cross-sectional view of the utility model battery receiving cavity structure.
In figure: 1- battery receiving cavity, 2- shell, 3- inner casing, the heat-insulated gap 4-, 5- venthole, 6- handle slot.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of battery case, comprising: three battery accommodating chambers
Body 1, three battery receiving cavity 1 are sequentially connected；Each battery receiving cavity 1 is provided with shell 2 and inner casing 3, inner casing 3
It is arranged in shell 2, heat-insulated gap 4 is provided between shell 2 and inner casing 3 and forms double-shell structure, the upper surface of shell 2 opens up
There are multiple ventholes 5, the quantity of venthole 5 is set as several, and venthole 5 takes symmetrical arranged side by side, 2 table of shell
The top and bottom of face side offer handle slot 6, this shell has explosion-proof, the anti-advantages such as area diffusion of catching fire, by wink
Between lithium battery group out of control catch fire to specify with blast and be discharged in top vent hole 5, will not be because of the box wink of conventional lithium battery group
Between thermal runaway and cause battery receiving cavity 1 to be raised, cause secondary catch fire that entire charge position is caused to cause the face that catches fire more greatly
Product injures personnel, and advantage is exactly that property can be effectively protected in lithium battery group runaway condition and do not cause directly to personnel directly
Injury is connect, the bigger area that catches fire will not be caused because lithium battery is on fire.
When work, new battery is put into the inner casing 3 of battery receiving cavity 1, battery is fully wrapped around by double-shell structure, and one
When the accidents such as denier battery collides, failure, after short circuit, have cavity insulation gap 4 to occupant in the battery case of bilateral
With protective effect, and moment lithium battery group out of control is caught fire and can be discharged in specified venthole 3 with blast.
It should be noted that, in this document, relational terms such as first and second and the like are used merely to a reality
Body or operation are distinguished with another entity or operation, are deposited without necessarily requiring or implying between these entities or operation
