Abstract
The utility model discloses a lithium ion battery, comprising a shell and an electric core, wherein an insulating layer for fixing the electric core and enabling the electric core to be suspended without contacting with the shell is arranged between the shell and the electric core. The lithium ion battery has the advantages that the insulating layer is used for fixing between the shell and the electric core to enable the electric core to be suspended, not only can effectively fix the position of the electric core, but also can play a role in insulation, so that external heat can not be transferred to the electric core.
Description
Technical field
The utility model relates to a kind of lithium ion battery.
Background technology
At present, still there are the following problems for the electronic bicycle industrialization of lithium ion battery: 1. shell sizes can not be unified, and causes the consumer to change inconvenience; The fail safe of lithium ion battery be always industry than more sensitive topic, mainly be there is heat radiation in battery in the situation of discharge problem, it is bad dispel the heat, causes the rising of module temperature, has potential safety hazard; 3. can be connected firmly degree and the degree of resistance to wearing of the monomer of battery in anabolic process adapt to lithium electricity bicycle riding under various comprehensive road conditions.
Summary of the invention
The utility model provides a kind of lithium ion battery, and the shell sizes that solves existing lithium ion battery can not be unified, the bad and problems such as firm and fail safe of battery case in the process of riding of comprehensive road condition of heat radiation in discharge process.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of lithium ion battery, comprise shell and battery core, be provided with between described shell and the battery core fixing battery core make battery core unsettled not with the thermal insulation layer of housing contacts.
Further, described thermal insulation layer is the foam glue-line.
Further, the two ends of described shell are provided with end cap, are provided with resilient coating between described end cap and the battery core.So that battery core is fallen the good cushioning effect of Shi Nengyou, resilient coating can be made with EV cotton or other materials with buffering effect, can be located on the end cap, also can be located at the battery core end.
Further, the madial wall of described shell is provided with raised line, and described raised line extends to the other end from an end of shell.
Further, described raised line is T shape raised line.
Further, described shell is fixedly connected with by screw with end cap.
Further, the two ends of the madial wall of described shell are provided with the thread groove with screw fit.
Further, described shell is rectangular tube, and described thread groove is located on four angles of shell.
Further, the center at long two ends on one side also is provided with described thread groove in the madial wall of described shell.
Further, described shell is the rectangular tube of 160mm * 110mm.
After adopting technique scheme, the utlity model has following advantage: fix with foamed glue between shell and the battery core, make battery core unsettled, foamed glue can also play heat-blocking action except effectively fixing battery core position, makes outside heat can not be delivered to battery core; Leave a blank as heat dissipation channel in the foamed glue gap simultaneously, can effectively play the heat Homogeneouslly-radiating that outside generation heat and battery core produce in discharge process.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
A kind of embodiment of the utility model as shown in Figure 1, a kind of lithium ion battery comprises shell 1 and battery core 2, be provided with between described shell and the battery core fixing battery core make battery core unsettled not with the thermal insulation layer 3 of housing contacts.Described thermal insulation layer is the foam glue-line.In order to solve the lithium ion battery bad problem of in discharge process, dispelling the heat, fix with foamed glue between shell and the battery core, make battery core unsettled, do not contact with any stiff dough, guarantee stressed being evenly distributed on each face, play the weak battery core of protection intensity; Foamed glue can also play heat-blocking action except effectively fixing battery core position, makes outside heat can not be delivered to battery core.The two ends of described shell are provided with end cap, are provided with resilient coating between described end cap and the battery core.So that battery core is fallen the good cushioning effect of Shi Nengyou, resilient coating can be made with EV cotton or other materials with buffering effect, can be located on the end cap, also can be located at the battery core end.
The madial wall of described shell is provided with raised line 11, and described raised line extends to the other end from an end of shell.Make foamed glue form the space at the raised line place, as heat dissipation channel, can effectively play the heat Homogeneouslly-radiating that outside generation heat and battery core produce in discharge process.Preferred described raised line is T shape raised line, and it is larger to form the space, strengthens heat radiation.In the present embodiment, long side arranges raised line everywhere, and the broadside side arranges two place's raised lines.
Described shell is fixedly connected with by screw with end cap.The two ends of the madial wall of described shell are provided with the thread groove 12 with screw fit.In above-described embodiment, described shell is rectangular tube, and described thread groove is located on four angles of shell.The center at long two ends on one side also is provided with described thread groove in the madial wall of described shell, increases bonding strength.Described shell is the rectangular tube of 160mm * 110mm, and this size refers to the size of lateral wall.In addition, battery core can be squeezed under abuse condition, and the battery core shell adopts high-strength aluminum alloy material, thereby can well protect battery core.
Except above preferred embodiment, the utility model also has other execution mode, those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
