Specific embodiment

In order to which technical problem to be solved in the utility model, technical solution and beneficial effect is more clearly understood, with Lower combination accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific reality described herein It applies example to be only used to explain the utility model, is not used to limit the utility model.

A kind of battery, as depicted in figs. 1 and 2, including shell 1, pole group 2 and cylinder 3, pole group 2 and cylinder 3 are separately mounted to The inside of shell 1, and cylinder 3 is provided with bulge-structure；When cylinder 3 is mounted in shell 1, the protrusion knot of 3 side of cylinder Structure is closely abutted with the inner surface of shell 1, is interference fitted the inner surface of cylinder 3 and shell 1.

By one cylinder 3 of interference installation in shell 1, the space in shell 1 is filled, and then makes the battery after assembly Internal structure is even closer, increases the structural strength and durability of battery；And cylinder 3 and shell 1 are interference fitted, and make battery Internal structure is not likely to produce shaking and abnormal sound.When the capacity difference of battery, the size of pole group 2 changes therewith；At this point, can be selected Different size of cylinder 3, to fill the inner space of shell 1, when making the volume change of battery, the whole size and shape of battery It will not change, there is preferable versatility.

Specifically, cylinder 3 may be configured as cylindrical plastic column, meanwhile, bulge-structure includes being integrally formed to be arranged in column The bar shaped of 3 side of body convex stupefied 31, and bar shaped convex stupefied 31 is extended along the axis direction for being parallel to cylinder 3；And bar shaped is convex Stupefied 31 quantity may be configured as three, and three bar shapeds convex stupefied 31 are evenly distributed on the side of cylinder 3 along the circumferential direction of cylinder 3. When assembling battery, first cylinder 3 is filled in shell 1 from the upper end opening of shell 1, after filling in shell 1 plasticity change occurs for cylinder 3 The inner surface of shape, the bar shaped of side convex stupefied 31 and shell 1 forms elastic extruding, so that 3 interference of cylinder be made to be mounted on shell 1 It is interior；Then it is sequentially loaded into pole group 2 and nut cap 4 from the upper end opening of shell 1, flange finally is carried out to the upper end opening of shell 1, is made Cylinder 3, pole group 2 and nut cap 4 are fixedly mounted within the case 1.

Further, shell 1 is additionally provided with the first interior male structure 11, the first interior male structure 11 be located at pole group 2 and cylinder 3 it Between.After battery assembly, pole group 2 and cylinder 3 are located at the two sides of the first interior male structure 11, and respectively with the first interior male structure 11 It abuts；First 11 pairs of interior male structure pole group 2 and cylinder 3 play the role of limit, are not likely to produce the internal structure of battery more Shaking and abnormal sound.Specifically, the first interior male structure 11 has convex surface in the first inner concave and first, the first inner concave is formed in shell The outer surface of body 1, and be recessed to the internal direction of shell 1；Convex surface is formed in the inner surface of shell 1 in first, and to shell 1 Internal direction protrusion.First interior male structure 11 can pass through the lateral surface progress in shell 1 after cylinder 3 is assemblied in shell 1 Slot rolling obtains, and installs pole group 2 and cylinder 3 in shell 1 stronger.

Further, bulge-structure further includes being integrally formed the annular flange 32 that 3 end of cylinder is arranged in, annular flange 32 Along cylinder circumferential direction be arranged, and with the first of the first interior male structure 11 in convex surface abut against.Cylinder 3, pole group 2 and nut cap 4 are pacified After dress is fixed in shell 1, convex surface is abutted in annular flange 32 and the first of the first interior male structure 11, and has bigger contact Area keeps the first interior male structure 11 more obvious to the position-limiting action of cylinder 3, and cylinder 3 is installed stronger.

In the present embodiment, shell 1 is equipped with the nut cap 4 being electrically connected with pole group 2, and nut cap 4 includes being integrally formed setting Mounting plate 41 and boss 42, mounting plate 41 are located in shell 1, and boss 42 then stretches out in shell 1 from the opening at 1 top of shell.Into One step, sealing ring 5 is installed, and mounting plate 41 is fixedly mounted in sealing ring 5 in shell 1, improves the internal junction of battery The leakproofness of structure.

Further, shell 1 is additionally provided with the second interior male structure 12, and the second interior male structure 12 is located at pole group 2 and sealing ring 5 Between, and abutted respectively with pole group 2 and sealing ring 5.After battery assembly, pole group 2 and sealing ring 5 are located at the second interior male structure Limit is played the role of to pole group 2 and sealing ring 5 respectively in 12 two sides, and the internal structure of battery is made more to be not likely to produce shaking And abnormal sound.Specifically, the second interior male structure 12 has convex surface in the second inner concave and second, the second inner concave is formed in shell 1 Outer surface, and to the internal direction of shell 1 be recessed；Convex surface is formed in the inner surface of shell 1 in second, and into shell 1 Portion direction protrusion.After battery assembly, pole group 2 and sealing ring 5 are abutted with convex surface in the second of the second interior male structure 12 respectively, and second Interior male structure 12 can carry out slot rolling in the lateral surface of shell 1 and obtain, make pole group 2 in shell after pole group 2 is assemblied in shell 1 It is installed in body 1 stronger.

In the present embodiment, the voltage of battery is 1.2V, capacity 600mAh, then the height 29mm of pole group 2；Cylinder 3 Height is 15mm, outer diameter 13.1mm；The width of protrusion 31 is 0.7mm, with a thickness of 0.15mm；The outer diameter of annular flange 32 is 13.5mm。

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.
