Technical solution is used by the utility model solves above-mentioned technical problem：

A kind of anti-flaming soft-package battery of drop resistant, including core body are coated on the plastic-aluminum packaging film in core external week and are connected to Positive and negative lug at the top of core body, the core external surface are enclosed equipped with supporting rack, between the core body and supporting rack and Heat-conducting silicone grease is filled in the cavity surrounded between supporting rack and plastic-aluminum packaging film.

In a preferred embodiment, it is enclosed with corner protector on the corner of the core body.

In a preferred embodiment, three protection faces of the corner protector are mutually 90 degree.

In a preferred embodiment, the material of the corner protector is CR foams.

In a preferred embodiment, the top of the heat-conducting silicone grease is equipped with silicone rubber cover.

In a preferred embodiment, it is corrugated plastics reed that support frame as described above, which is section,.

In a preferred embodiment, the thickness of the heat-conducting silicone grease is 5mm.

In a preferred embodiment, the outer cover of the positive and negative lug is equipped with insulation sleeve.

The utility model has the beneficial effects that：The utility model is improved by the structure to soft-package battery, in battery Inside setting supporting rack and heat-conducting silicone grease, can not only make the heat Quick diffusing that battery is generated in charge and discharge go out, and improve Heat dissipation effect, additionally it is possible to avoid the occurrence of battery and cause situation on fire because collision leads to core internal short-circuit, improve Soft Roll The drop resistant of battery and anti-flaming performance.

Description of the drawings

The utility model is described further with reference to the accompanying drawings and examples.

Specific implementation mode

The technique effect of the design of the utility model, concrete structure and generation is carried out below with reference to embodiment and attached drawing Clear, complete description, to be completely understood by the purpose of this utility model, scheme and effect.It should be noted that not conflicting In the case of, the features in the embodiments and the embodiments of the present application can be combined with each other.

It should be noted that unless otherwise specified, when a certain feature is referred to as " fixing ", " connection " is in another feature, It can directly fix, be connected in another feature, can also fix, be connected in another feature indirectly.In addition, this The descriptions such as the upper and lower, left and right used in utility model are only the phase relative to each component part of the utility model in attached drawing For mutual position relationship.

In addition, unless otherwise defined, the technology of all of technologies and scientific terms used here by the article and the art The normally understood meaning of personnel is identical.Term used in the description is intended merely to description specific embodiment herein, without It is to limit the utility model.Term " and or " used herein includes appointing for one or more relevant Listed Items The combination of meaning.

Fig. 1, Fig. 2 are the structural schematic diagram in the utility model one embodiment both direction respectively, referring to Fig.1, Fig. 2, The soft-package battery includes core body 1, heat-conducting silicone grease 2, silicone rubber cover 3, insulation sleeve 4, anode ear 5, negative electrode lug 6, corner protector 7, supporting rack 8, plastic-aluminum packaging film 9.

As shown in Figure 1, anode ear 5 is connected to the top of core body 1, the periphery of anode ear 5 and negative electrode lug 6 with negative electrode lug 6 It is cased with one layer of insulation sleeve 4, which positive and negative lug is isolated with other media in addition to core body 1.1 top of core body Equipped with a silicone rubber cover 3, which is provided with two through-holes passed through for lug and insulation sleeve 4, silicone rubber cover 3 and core body 1 Contact portion in step-like, the upper surface of core body 1 is higher than the lower surface of silicone rubber cover 3, therefore silicone rubber cover 3 can be looped around pole With 1 top of core body around ear, battery is effectively prevent to go out situations such as lug loosening, 1 corner of core body rupture caused by colliding with It is existing.

It is all enclosed with corner protector 7 on 8 corners of the core body 1 of the present embodiment, as shown in figure 3, corner protector 7 wraps up core body side Three protection faces at angle are connected with each other and are mutually 90 degree, because CR foams have resistance to combustion, oil resistant, corrosion resistant excellent specific property, therefore CR foam materials can be selected in corner protector 7, and corner protector 7 provides battery under the premise of silicone rubber cover 3 protects 1 top of core body Further protection is avoided when battery is fallen because collision causes battery edge to cause short-circuit fire because cladding is bad.

The periphery and bottom surface of core body 1 are surrounded by supporting rack 8, and supporting rack 8 is located at below silicone rubber cover, as shown in Fig. 2, support Frame 8 is bent to the thin slice cylinder of section undulate, and supporting rack 8 can be plastics reed and have good electrical and thermal conductivity and bullet Property, thus supporting rack 8 can not only rapid cooling, certain cushioning effect can also be provided, can prevent because over-charging of battery, cross put The case where expansion causes plastic-aluminum packaging film to rupture occurs.

Be enclosed with plastic-aluminum packaging film 9 outside supporting rack 8 and silicone rubber cover 3, plastic-aluminum packaging film 9 and supporting rack 8, supporting rack 8 with Be filled with heat-conducting silicone grease 2 in the cavity that core body 1 surrounds, heat-conducting silicone grease 2 be placed in the lower section of silicone rubber cover 3 and with the upper table of supporting rack 8 Face flushes, and the thickness of heat-conducting silicone grease 2 may be configured as 5mm, cannot be in time by core body 1 because filling because air is the non-conductor of heat The heat transfer that electric discharge generates is gone out, and heat-conducting silicone grease 2 can squeeze out air from the gap in battery, keep contact surface more preferable Come into full contact with, therefore inside battery can effectively transmit heat, improve the heat dissipation performance of battery, and supporting rack 8 can be with Coordinate with heat-conducting silicone grease 2, the gap between 1 bottom of core body and laminated aluminum film film 9 is supported, prevents battery bottom from collapsing It falls into, certain buffering and supporting role in addition to this can also be played to battery.

It is to be illustrated to the preferable implementation of the utility model, but the invention is not limited to the reality above Example is applied, those skilled in the art can also make various equivalent variations without departing from the spirit of the present invention Or replace, these equivalent deformations or replacement are all contained in the application claim limited range.
