Abstract
The utility model relates to an anti-vibration lithium battery which comprises a housing, a cover plate, a winding pole piece located in the housing, and a current collector connected with the pole piece, wherein the current collector is an arc body which is formed by radially leading out of the housing and bending; and the arc body is strip-shaped, and is welded with an inner wall of the housing in a matching manner. According to the lithium battery, the current collector adopts a radial lead-out manner, is designed to be arc, and is welded on the inner wall of the battery housing, so that winding core fixing is improved, and the anti-vibration capacity of the battery is improved; and in addition, the anti-vibration capacity is improved and no additional fixing device is increased, so that cost investment is reduced, and an internal structure of the battery is simplified.
Description
Technical field
The utility model relates to technical field of lithium batteries, is specifically related to a kind of antivibration lithium battery.
Background technology
Collector is the element that inside battery is commonly used, and plays the effect that collects electric current and guide current.Collector welds and in the metal tape, lithium ion battery of positive plate end face, connects the metal tape that is connected battery core body and protection circuit in the metal tabs at utmost point group sheet and battery the two poles of the earth and battery of mobile phone in the common application form of inside battery is included in Ni-Cr battery.Common, be applied in collector in box hat or aluminum-shell lithium battery and connecting pole piece and draw along the direction of vertical battery bottom, and be pressed between battery container and battery cover board.Although this current collector structure of lithium battery plays catchment effect, volume core is not had to good supporting role.When battery is when vibrated, the negative plate of coiling, because of the upper and lower displacement of fixed effect missionary society, even causes collector fracture and cause battery failure.
In order to improve vibration resistance, those skilled in the art propose to install a support ring above volume core.Volume core is close in the bottom of this support ring, and top is pressed by battery cover board, to limit the displacement in the vertical direction of volume core.Although this project organization plays certain antivibration effect, has the deficiency that reliability is low.Reason is, for the sake of security, the nonconducting plastic cement material of the normal employing of this support ring, separately consider corrosion resistant requirement, the most common PTFE(polytetrafluoroethylene of selecting) material, and that PTFE material there will be when standing high temperature is softening, thereby mechanical strength significantly reduces, and is difficult to fix reliably volume core.
Those skilled in the art also propose to install additional metal retainer ring in battery, and at inner spot welding one becket of battery container, its Ge is close to the volume core top of coiling, for fixing volume core.Although this project organization has been improved the low deficiency of plastic cement material support ring reliability, because retainer ring is mechanism independently with respect to volume core, therefore need to complete spot-welding technology pressing volume core Wei Ge, very easily cause in this context spot-welding technology unstable.Meanwhile, the extra retainer ring increasing has increased cost input.
Utility model content
This practical purpose is to overcome weak point of the prior art, provide a kind of additionally do not increase volume core fixed structure and vibration resistance strong antivibration lithium battery.
The purpose of this utility model is achieved through the following technical solutions:
An antivibration lithium battery, comprises housing, cover plate, is positioned at the pole piece of enclosure interior coiling and the collector being connected with pole piece, and described collector is a metal tape of radially being drawn by housing, and mates welding with inner walls.
In such scheme, inventor innovates on collector lead-out mode, changes the traditional approach of collector axial lead, adopts the mode that collector is radially drawn.Flow collection band of the present invention, Heng is the afterbody at pole piece Xiang She Ge, and after coiling, flow collection band is positioned at volume core outside and is close to battery container inwall, by by this flow collection band and the spot welding of box hat inwall, can effectively play the effect of fixing volume core, thereby improve vibration resistance.And the utility model is not additionally increasing on the basis that is fixed dress Ge, the lifting of complete battery pair vibration resistance is also one of large innovative point.
As optimal technical scheme, described flow collection band is pure nickel band or stainless steel band.
The utility model has the following advantages and beneficial effect compared to existing technology:
(1) the utility model adopts lead-out mode radially by collector, and collector is welded on to battery container inwall, has improved fixing to pole piece, thereby improves the vibration resistance of battery;
(2) the utility model raising vibration resistance does not additionally increase and is fixed dress Ge, has reduced cost input, has simplified inside battery structure;
(3) the utility model is convenient to promote and is realized;
(4) the utility model has increased contact area and the firm degree of collector and battery container, thereby has further improved afflux ability and the stable discharging ability of battery.
Accompanying drawing explanation
Fig. 1 is the utility model antivibration lithium battery interior structure explosive view.
Fig. 2 is traditional collector deriving structure schematic diagram.
Fig. 3 is the utility model collector deriving structure schematic diagram.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but the execution mode that the utility model is created is not limited to this.
As shown in Figure 1, a kind of antivibration lithium battery, comprise housing 1, cover plate 2, be positioned at housing 1 interior roll around pole piece (pole piece be included in volume core 3, in figure, do not indicate) and the collector 4 that is connected with pole piece, collector 4 is one by housing 1, radially to be drawn and the circular arc body 41 that forms of bending, it is banded that circular arc body 41 is, and central angle is 180 degree, and the outer surface of circular arc body 41 and housing 1 inwall agree with welding.
In the specific implementation, the width of circular arc body 41 is determined according to the overall volume of battery, and according to the specification of conventional battery, the width of circular arc body 41 can be designed to 5-10mm.And circular arc body 41 adopts metal materials, both played afflux effect, avoid again adopting plastic material to occur easily softening deficiency of high temperature, the material of concrete employing is pure nickel or stainless steel material.
Shown in Fig. 2 and Fig. 3, the collector 4 that can find out very intuitively conventional batteries is vertically drawn in volume core 3, and the collector 4 of antivibration lithium battery of the present invention is radially drawn, and Heng Xiang She Ge the afterbody at pole piece.
What deserves to be explained is, the utility model in the specific implementation, has following beneficial effect:
Collector is adopted to lead-out mode radially, and current collectors design is become to circular-arc, be welded on battery container inwall, improved fixing to pole piece, thereby improve the vibration resistance of battery;
Improve vibration resistance and additionally do not increase and be fixed dress Ge, reduced cost input, simplified inside battery structure and be convenient to promote and realized;
Increase contact area and the firm degree of collector and battery container, thereby further improved afflux ability and the stable discharging ability of battery.
The above embodiment has only expressed execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, not departing under prerequisite of the present utility model, can also make some distortion and improvement, these all belong to the protection range of this practical virtual property.Therefore, the protection range of the utility model patent should be as the criterion with claims.
