Description
Technical field
The present invention relates to a kind of cell apparatus, relate in particular to a kind of safety type Li ion cells unit.
Background technology
Lithium ion battery is a kind of rechargeable battery, and it mainly relies on lithium ion to move work between positive pole and negative pole.In charge and discharge process, Li+ comes and goes embedding and takes off embedding between two electrodes: during rechargable battery, Li+ takes off embedding from positive pole, embeds negative pole through electrolyte, and negative pole is in rich lithium state; Then opposite during discharge.The general employing contained the material of elemental lithium as the battery of electrode.It is the representative of modern high performance battery.
But existing Li ion cells unit lacks the necessary security assembly, in case expanding appears in battery, causes potential safety hazard easily.
Summary of the invention
Purpose of the present invention is exactly in order to solve the above-mentioned problems in the prior art, and a kind of safety type Li ion cells unit is provided.
Purpose of the present invention is achieved through the following technical solutions:
A kind of safety type Li ion cells unit, include the battery accommodating box, wherein: be provided with lithium ion battery in the described battery accommodating box, be distributed with lug on the described lithium ion battery, be distributed with feed-through assembly on the described battery accommodating box, described feed-through assembly contacts with lug, described lithium ion battery is provided with main security component, the position of corresponding main security component is provided with supporting security component in the described battery accommodating box, is provided with the safety clearance between main security component and the supporting security component.
Further, above-mentioned a kind of safety type Li ion cells unit, wherein: described main security component is air bag, and described supporting security component is the prong device, and the needle point of described prong device is under normal conditions and be provided with the safety clearance between the air bag.
Further, above-mentioned a kind of safety type Li ion cells unit, wherein: be provided with interlayer in the described air bag.
Again further, above-mentioned a kind of safety type Li ion cells unit, wherein: be distributed with reinforcement in the described battery accommodating box.
The advantage of technical solution of the present invention is mainly reflected in: rely on cooperating of main security component and supporting security component, can in time realize the safety relief to lithium ion battery, promoted the safe coefficient of using.And, simple structure of the present invention, low cost of manufacture is easy to promote.
Description of drawings
Purpose of the present invention, advantage and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain.These embodiment only are the prominent examples of using technical solution of the present invention, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the scope of protection of present invention.In the middle of these accompanying drawings,
Fig. 1 is the organigram of safety formula Li ion cells unit.
Embodiment
A kind of safety type Li ion cells unit as shown in Figure 1 includes battery accommodating box 1, its unusual being: be provided with lithium ion battery 2 in the battery accommodating box 1 of the present invention.Specifically, be distributed with lug 3 on this lithium ion battery 2.Correspondence is with it, is distributed with feed-through assembly 4 on this battery accommodating box 1, makes feed-through assembly 4 contact with lug 3.Simultaneously, lithium ion battery 2 is provided with main security component, and the position of corresponding main security component is provided with supporting security component in battery accommodating box 1.And, set out in order to prevent mistake, between main security component and supporting security component, be provided with the safety clearance.Like this, satisfying under normal conditions, main security component can not contact with supporting security component.
With regard to the present invention's one preferred implementation, for the ease of realizing that improve safe coefficient, the main security component of employing is air bag 5, supporting security component is prong device 6, and the needle point of prong device 6 is provided with the safety clearance under normal conditions and between the air bag 5.Like this, in case expanding appears in lithium ion battery 2, will reduce the safety clearance, cause air bag 5 contact needle points, make air bag 5 reveal, realize the pressure release equilibrium.
Further, for the useful life of scapegoat's air bag 5, be provided with interlayer 7 in this air bag 5.And, in battery accommodating box 1, be distributed with reinforcement, improve the durable degree of entire cell device.
By above-mentioned character express as can be seen, adopt the present invention after, rely on cooperating of main security component and supporting security component, can in time realize the safety relief to lithium ion battery, promoted the safe coefficient of use.And, simple structure of the present invention, low cost of manufacture is easy to promote.
