It is preferred embodiment provided by the utility model shown in referring to Fig.1~8.
The shell mechanism of battery provided by the utility model, the containment weight for solving lithium battery is larger, is unfavorable for not
Conducive to shell transport and subsequent assembly the problem of, also can be used in other various types of batteries, be not limited only to this reality
Apply example.
The shell mechanism of battery, including shell, the shell are in tetragonal body shape, and according to actual needs, shell also may be configured as
Other shapes；The inside of shell is formed with the cavity 13 for accommodating battery core, and there is the top of connection cavity 13 to open at the top of shell
Mouthful, in battery assembling process, battery core is placed in the inside of shell, opening of the top closure in shell, so that battery is constituted
One complete overall structure is realized to extraneous power supply；The bottom of shell has positioned opposite with the top opening of cavity 13
Bottom plate 11, bottom plate 11 has the outer end face away from cavity 13, and the outer end face of bottom plate 11 is provided with groove 12 in long strip.
The shell mechanism of the battery of above-mentioned offer is arranged fluted 12 by the outer end face in bottom plate 11, in this way can be
In the case where not influencing shell service performance, the weight of shell is reduced, convenient for the transport and subsequent assembly of shell.Meanwhile
Material required for manufacture shell is decreased, the production cost of shell is reduced.In this way, solving outside the biggish battery of thickness
The problem of shell weight is larger, is unfavorable for the transport and subsequent assembly of shell.
Specifically, the length extending direction of groove 12 and the length extending direction of bottom plate 11 are consistent.In this way, being convenient for groove 12
Arrangement on bottom plate 11, convenient for the production of battery case.
Specifically, the bottom plate 11 of shell is provided with multiple grooves 12.It, in this way can be in not shadow by the way that multiple grooves 12 are arranged
In the case where ringing shell service performance, the weight of shell is further reduced.In the present embodiment, work is arranged there are six groove 12,
It is separately arranged between each groove 12.
In the present embodiment, the depth of each groove 12 is identical, this way it is possible to avoid single 12 depth of groove is excessive, shadow
The service performance of shell is rung, and sets identical for the depth of each groove 12, is also convenient for the manufacture of groove 12, improves shell
Production efficiency.
In the present embodiment, each groove 12 is separately arranged, and groove 12 is arranged in parallel two-by-two, forms groove group.
By forming groove group, so that arrangement more orderly between each groove 12, convenient for the use of shell.
Specifically, each groove group is arranged along the length extending direction of bottom plate 11.In this way, enabling each 12 phase of groove
To being uniformly arranged on bottom plate 11, so that the distribution of weight of shell is uniform, be conducive to the assembly and use of shell.
In the present embodiment, arc-shaped transition between the bottom of groove 12 and the side wall of groove 12.In this way, making groove 12
It is seamlessly transitted between bottom and the side wall of groove 12, is conducive to the cleaning of surface of shell.
In addition, the side wall of cavity 13 is convexly equipped with multiple support bars 14, multiple support bars 14 are respectively provided with towards top opening
The support end face 141 in direction, support end face 141, which is used to support, is sealed on open-topped battery cap, pacifies when by battery cap
When on the shell mechanism of the battery, the lower end surface of the cavity 13 of battery cap direction then abuts the support end of support bar 14
Face 141, to prevent battery cap from falling into cavity 13.
Also, support bar is in long strip, and above-mentioned support bar 14 is disposed to extend along bottom plate 11 to open-topped direction, this
Sample, this multiple support bar 14 can not only play a supportive role to battery cap, meanwhile, extend cloth along bottom plate 11 to top opening direction
The support bar 14 set is used as a kind of reinforcing rib, keeps the shell mechanism of the battery more stable, is not susceptible to deform, also, in length
The support bar 14 of strip is compared to the support construction for being used to support battery cap being covered in 13 side wall of cavity, occupied sky
Between it is less, thus reduce the volume and weight of the shell mechanism of the battery, transport and subsequent dress in order to shell
Match.
In embodiment 1, support bar 14 is arranged in four chamfering positions in the cavity 13 of the four directions body case, and
And the two sides of support bar 14 are located on the side wall of cavity 13, the rounded transition in side to the other side of support bar 14, round-corner transition
Radius be greater than the chamferings of 13 two sidewalls of cavity, support bar 14 is transitioned into the side wall of cavity 13 then towards open-topped upper end
Above-mentioned support end face 141 is formed, along side wall to the upper end of support bar 14, end face 141 is supported to tilt towards bottom plate 11, this
Sample, when battery cap covers top opening, the support end face 141 of inclination arrangement allows battery cap and open-topped cooperation
There are certain errors, convenient for the installation of battery cap；Also, sky when being arranged in the support bar 14 of chamfering position inside cavity 13
Between will not reduce, the components such as battery core are also convenient for placing.
And in example 2, multiple support bars 14 are located on the side wall of two sides and are arranged symmetrically, and the two of support bar 14
The side wall arc-shaped transition of side and cavity 13, the support bar 14 on side wall make the cavity on bottom plate 11 to top opening direction
The active force that 13 side walls are able to bear is bigger, and the shell mechanism of the battery is made to be not susceptible to deform.
In embodiment 3, support bar 14 is located on chamfering and side wall, while end face 141 being supported to be in tilted layout, and makes electricity
While pool structure is stablized, excessive space will not be occupied, and fix convenient for the installation of battery cap.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
