Description
Technical field
The utility model relates to field of batteries, refers in particular to a kind of lithium battery group.
Background technology
Lithium battery is a class is negative material, the battery using non-aqueous electrolytic solution by lithium metal or lithium alloy.Because the chemical characteristic of lithium metal is very active, make the processing of lithium metal, preservation, use, very high to environmental requirement.So lithium battery is not applied for a long time.Along with the development of science and technology, present lithium battery becomes main flow.
At present, in order to adapt to the relatively large equipment such as automobile, battery vehicle, usually lithium battery series connection is formed lithium battery group, and the quality of lithium battery group and coefficient of safety mainly rely on single lithium battery, if lithium battery produces gas, or overcharge, voltage control shakiness causes battery surface to heave, inside battery material gets muddled, then battery such as easily to explode at the potential safety hazard.
Summary of the invention
The purpose of this utility model is for the existing state of the art, provides a kind of lithium battery group, and power brick is heaved and made silica gel piece deformation, with trigger alarm device, realizes hidden danger in time and gets rid of.
For achieving the above object, the utility model adopts following technical scheme:
The utility model is a kind of lithium battery group, mainly there is battery case, described battery case inner surface has layer of silica gel, evenly distributed some power brick in battery case, and in the middle of adjacent two power brick, there is silica gel piece, have cavity in described silica gel piece, the chamber wall of cavity two correspondence is provided with contact, and the warning device in two contacts and battery case is electrically connected.
In such scheme, some power brick upper ends all connect silicone tube, and silicone tube upper end through-silicon glue-line, battery is vented by silicone tube.
Further, silicone tube upper end is curved, prevents liquid from flowing into.
In such scheme, above battery case, there is cover plate, the anodic-cathodic of some power brick and cover plate is connected.
Further, battery case is plastic material.
Further, battery case two side has air-vent, and air-vent is positioned at above layer of silica gel.
As preferably, warning device is indicator light or buzzer.
The beneficial effects of the utility model are:
1. detect battery whether to heave, get rid of potential safety hazard in time;
2. silicone tube can get rid of the gas that battery produces, and top arc can prevent liquid from flowing backwards, and extends battery;
3. there is the advantages such as shockproof, moistureproof, dust-proof.
accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of the utility model.
embodiment:
Can have the object of the utility model, feature and function to make juror and further understand, hereby lift preferred embodiment and coordinate graphic being described in detail as follows:
Refer to shown in Fig. 1, it is the structural representation of the preferred embodiment of the utility model, the utility model is a kind of lithium battery group, mainly have battery case 1, described battery case 1 inner surface has layer of silica gel 11, evenly distributed some power brick 2 in battery case 1, and in the middle of adjacent two power brick 2, there is silica gel piece 3, battery case 1 is plastic material, has cover plate 12 above battery case 1, the anodic-cathodic 7 of some power brick 2 and cover plate 12 is connected.Have cavity 4 in described silica gel piece 3, the chamber wall that cavity 4 liang is corresponding is provided with contact, contact 51, two 51 and is electrically connected with the warning device 5 in battery case 1, when power brick 2 is heaved, elasticity of compression silica gel piece 3, makes two contacts 51 in silica gel piece 3 cavity 4 contact, to connect warning device 5.Wherein, warning device 5 is indicator light or buzzer, can notify that people's battery has potential safety hazard in time.
In such scheme, some power brick 2 upper ends all connect silicone tube 21, and silicone tube 21 upper end through-silicon glue-line 11, and silicone tube 21 upper end is curved, silicone tube 21 can help power brick 2 Exhaust Gas in time, and the cambered design of silicone tube 21 upper end can prevent the steam above layer of silica gel 11 or liquid from flowing backwards, increase the service life; Meanwhile, battery case 1 two side has air-vent 13, and air-vent 13 is positioned at above layer of silica gel 11, makes gas discharge the external world in time, avoids producing steam.
Certainly, above diagram is only the utility model better embodiment, not limits the scope of application of the present utility model with this, therefore, every make in the utility model principle equivalence change all should be included in protection range of the present utility model.
