Abstract
The invention relates to a lithium ion battery shell, which comprises a shell with a U-shaped section, wherein positioning grooves are uniformly arranged on the surface of the shell at intervals along the length direction of the shell, the positioning grooves on one side surface and the positioning grooves on the opposite side surface are arranged in a staggered manner, uniform salient points are arranged on the surface of the shell, and the salient points can enable the vertexes of the opposite salient points to be contacted after the two shells are combined through the positioning grooves, so that an air circulation channel for heat dissipation is formed on the combined surface. The invention not only facilitates the assembly and the positioning of the battery, but also can effectively dissipate the heat generated in the working process of the battery because the air circulation channel for heat dissipation is formed on the junction surface after the battery is assembled by the positioning groove.
Description
Technical field
The invention belongs to technical field of lithium ion, and in particular to a kind of casing of lithium ion battery.
Background technology
At present, the application of lithium ion battery is more and more extensive, for bigger voltage, generally in use, can be by
Multiple cells, which are assembled, to be formed battery pack and uses, and the battery apparatus for forming multiple batteries when universal at present is in battery
In case, but common battery case is plane, after so assembling, can not be mutually located between battery, and between battery
Contact surface be plane, there is the problem of radiating effect is poor.
The content of the invention
A kind of perfect heat-dissipating and ease of assembly battery pack are provided it is an object of the invention to solve above-mentioned technical problem
Casing of lithium ion battery.
To achieve the above object, the present invention is using according to lower technical scheme：
A kind of casing of lithium ion battery, including the shell that section is U-shape, the length side of the surface of the shell along shell
To having set up evenly spaced locating slot, and the locating slot of one side and the locating slot of opposite flank are staggered setting, described outer
The surface of table has uniform salient point, and the salient point can make two shells make relative salient point after being combined by the locating slot
Summit be in contact and form the air communication channel for radiating in faying face.
The locating slot is oat tail groove structure.
The salient point is circular salient point, and the height of the salient point is 1-2mm, a diameter of 3-4mm, mutual at intervals of 3-
4mm。
The present invention has set up evenly spaced locating slot, and one side due to the length direction on the surface of shell along shell
Locating slot and the locating slot of opposite flank be staggered setting, the surface of the appearance has uniform salient point, and the salient point can make
Two shells are combined by the locating slot and form the air communication channel energy for radiating after faying face, so not only
The assembling positioning of battery is facilitated, and the sky for radiating is formed after faying face due to being combined by the locating slot after assembling
Air-flow circulation passage, so effectively can effectively be exhaled to the heat produced in cell operations.
Brief description of the drawings
Fig. 1 show the main structure diagram of casing of lithium ion battery provided in an embodiment of the present invention；
Fig. 2 is the schematic top plan view of the combination connection of two shells；
Fig. 3 is the schematic diagram of salient point formation air communication channel.
Embodiment
Below, the substantive distinguishing features and advantage of the present invention are further described with reference to example, but not office of the invention
It is limited to listed embodiment.
Refer to the shell 1 that Fig. 1-3, a kind of casing of lithium ion battery, including section are U-shape, the surface of the shell
Evenly spaced locating slot 2, and the locating slot and the locating slot phase of opposite flank of one side have been set up along the length direction of shell
Stagger the side of setting, i.e., one for locating slot, then the relative position in another side and the locating slot can clamping location fits
Limiting section 4 is protruded, the surface of the appearance has uniform salient point 3, and the salient point 3 can make two shells pass through the positioning
After groove is combined, the summit of relative salient point is set to be in contact and form the air communication channel 5 for radiating in faying face.
Wherein, the shell is made using aluminium material or plastic material.
Wherein, the salient point is circular salient point, preferably semicircular salient point.
It should be noted that due to located at salient point, can not only form the air communication channel, it is convenient to radiate, and by
Also increase the surface area of shell in itself in salient point, be more beneficial for radiating.
It is preferred that, the locating slot 2 is oat tail groove structure, and the width of the locating slot 2 is less than connected plane area
Width, the locating slot 2 is evenly arranged, and the groove depth of the locating slot is 3-4mm.
Wherein, the locating slot 2 is formed for the sheet material of a housing by extruding brake forming.
It is preferred that, the height of the salient point is 1-2mm, a diameter of 3-4mm, mutual at intervals of 3-4mm, and battery
After shell is combined, the summit of corresponding salient point is in contact, after two such shells are combined by described locating slot, so that
The air communication channel in the wide gaps of 2-4mm that can be formed between the shell being combined, facilitates battery to be radiated.
Fig. 1-2 is only to show the structure for having locating slot in two relative sides of shell, certainly, if necessary to shell
Two other relative side also to arrange corresponding battery, then can also be set in the relative side of another two by the explanation stated
Fixed corresponding locating slot, and corresponding salient point is set.
The present invention has set up evenly spaced locating slot, and one side due to the length direction on the surface of shell along shell
Locating slot and the locating slot of opposite flank be staggered setting, the surface of the appearance has uniform salient point, and the salient point can make
Two shells are combined by the locating slot and form the air communication channel energy for radiating after faying face, so not only
Facilitate battery in battery case assembling positioning, after being installed in battery case will not displaced posi, and assembling after by
The air communication channel for radiating is formed after faying face in being combined by the locating slot, so can be effectively to battery work
The heat produced during work is effectively exhaled.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
