Abstract
The utility model relates to a lithium ion battery pack which comprises a shell and a battery unit, wherein a buffer cushion is arranged between the shell and a battery supply and comprises an outer weaving layer contacted with the shell, an inner weaving layer contacted with the battery supply and a core stem layer connecting the outer weaving layer and the inner weaving layer. Each core stem of the core stem layer is '8'-shaped. The core stem layer is formed by reversely interweaving pile warps between the outer weaving layer and the inner weaving layer. The lithium ion battery pack provided by the utility model has the advantages that the battery unit is not exposed and prevented from being contacted with the shell.
Description
Technical field
The utility model relates to the storage battery field, particularly a kind of lithium ion battery bag.
Background technology
At present, the structure of the lithium ion battery bag on market is: the lithium ion battery bag is comprised of the battery unit in housing and housing.The shortcoming of this lithium ion battery bag is: housing earthquake and shock are lower easily damaged, poor to the buffer capacity of collision.Because housing common metal material is made, housing breaks and easily with battery unit, contacts afterwards, and causes between battery unit being short-circuited, and damages battery unit.
For the poor shortcoming of the buffer capacity that overcomes housing, Chinese patent ZL200820047961.8 has disclosed a kind of storage battery, and this storage battery comprises housing, and at least one sidewall of housing is provided with cavity.Utilize cavity to come damp impacts and concussion.The shortcoming of this storage battery is: in case housing is acutely clashed into and ftractures, can't stop the extension in crack; And after the housing cracking, battery unit directly exposes, and battery unit easily contacts with housing simultaneously, causes being short-circuited between battery unit, damages power brick.
The utility model content
In order to overcome existing lithium ion battery pack housing, be knocked after cracking and be prone to battery unit and expose and with battery unit, contact with housing and cause the phenomenon of short circuit, the utility model provides a kind of battery unit of can protecting not expose and stop the lithium ion battery bag that battery unit contacts with housing.
The lithium ion battery bag, comprise shell and battery unit, it is characterized in that: be provided with cushion pad between shell and battery supply, cushion pad comprises the outside braid with housing contacts, the stem stem layer of braid and inboard braid with the inboard braid of battery supply contact and outside being connected, the stem stem layer is by the reverse formation that interweaves between outer organization level and inboard braid of suede warp.
Further, the single stem stem of stem stem layer is 8-shaped.
Further, in the stem stem layer, be full of filler.
Further, on cushion pad, be distributed with equably louvre, the quantity of louvre is a plurality of.
Outside braid and inboard braid can be that plain weave, twill weave or plain weave change braiding.
Benefit of the present utility model is: 1, when power brick is clashed into and shake, cushion pad can absorption portion impact, and strengthens the resistance to impact of shell and makes impact can directly not be passed to battery unit.
2, cushion pad is between shell and battery unit, even outer casing rupture, cushion pad can stop shell to contact with battery unit, plays the effect of insulation protection.
When 3, the outside braid of cushion pad or inboard braid broke, the stem stem layer played the effect that stops breach to extend, and avoids breach to extend rapidly.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the front view of cushion pad.
Embodiment
The lithium ion battery bag, comprise shell 1 and battery unit 3, between shell 1 and battery supply, be provided with cushion pad 2, cushion pad 2 comprises the outside braid 21 contacted with shell 1, inboard braid 22 and the stem stem layer 23 that is connected outside braid 21 and inboard braid 22 with the battery supply contact, the single stem stem of stem stem layer 23 is 8-shaped, and stem stem layer 23 is by the reverse formation that interweaves between outer organization level and inboard braid 22 of suede warp.
Outside braid 21 can be that plain weave, twill weave or plain weave change braiding with inboard braid 22.
In stem stem layer 23, be full of filler.Filler can strengthen the buffer capacity of cushion pad 2.
On cushion pad 2, be distributed with equably louvre, the quantity of louvre is a plurality of.
Below illustrate the weaving method of resilient coating: outside braid 21 is by the first upper strata body warp a1, the second upper strata body warp a2 and the upper layer weft yarns a3 formation that interweaves, inboard braid 22 is by the first body warp a4 of lower floor, the second body warp a5 of lower floor and the weft yarn a6 of the lower floor formation that interweaves, the weft yarn a6 of lower floor of the outside upper layer weft yarns a3 of braid 21 and inboard braid 22 all with the first suede through a7, the second suede interweaves through a8, the first suede through a7 and the second suede when a8 knits to the inside braid 22 from outside braid 21, space trend between two braids is opposite with the wefting insertion direction a9 of braid, the first suede interweaves and forms stem stem layer 23 through a8 through a7 and the second suede.The height of stem stem layer 23 is 0 ~ 50mm.
The first suede is all with same upper layer weft yarns a3 or the same weft yarn a6 of lower floor, to interweave simultaneously through a8 through a7 and the second suede when arbitrary braid interweaves.
Benefit of the present utility model is: 1, when power brick is clashed into and shake, cushion pad 2 can absorption portion impact, and strengthens the resistance to impact of shell 1 and makes impact can directly not be passed to battery unit 3.
2, cushion pad 2 is between shell 1 and battery unit 3, even shell 1 breaks, cushion pad 2 can stop shell 1 to contact with battery unit 3, plays the effect of insulation protection.
When 3, the outside braid 21 of cushion pad 2 or inboard braid 22 broke, stem stem layer 23 played the effect that stops breach to extend, and avoids breach to extend rapidly.
The described content of this specification embodiment is only enumerating the way of realization of utility model design; protection range of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection range of the present utility model also reaches the equivalent technologies means that design can be expected according to the utility model in those skilled in the art.
