Summary of the invention
Therefore, the present invention proposes in order to address the above problem a little at one stroke, its major subjects is: might not need the design alteration of lead accumulator, additional remove the contained acid mist of the gas of discharging from lead accumulator and prevent the function of igniting from the outside, and make the configuration of porous part simple and reliable, can not lose the degassing function of the porous part that consists of filter, the electrolyte leakage that just can slow down suppresses electrolyte leakage and arrives the outside to the speed of outside batteries.
That is, the lead accumulator that the present invention relates to is characterised in that to possess:
Exhaust flow path, this exhaust flow path are arranged on the electric groove that stops up electric groove and cover, and the gas channeling that will emit in the electric groove is outside; And
Porous part, this porous part are arranged on described exhaust flow path,
Described exhaust flow path has stream down, and described porous part is contacted with the side wall inner surfaces that forms described stream down, thereby at least a portion of described porous part is configured in described stream down.
According to this structure, because at least a portion of porous part is configured in the stream down of exhaust flow path, so the electrolyte that can slow down leaks into the speed of outside batteries from exhaust flow path, can suppresses electrolyte and leak into outside batteries by exhaust flow path.In addition, because being contacted with, porous part forms down that the side wall inner surfaces of stream configures, so can make porous part simplifies with respect to the contraposition of stream down, and can the reliable placement porous part, even be not provided in addition the fixedly mechanism of porous part, the dislocation that yet is difficult to produce porous part.Especially can prevent reliably that porous part from staggering in stream down downwards.And then, due to only by the porous part of packing at the stream down of exhaust flow path, so need not change the design of existing lead accumulator, can apply flexibly the structure of existing lead accumulator and configure porous part simple and reliablely, and can simplify the manufacturing of lead accumulator.In addition, in porous part gas by direction for down, even at porous part impregnation electrolyte, the moving direction of the electrolyte of this impregnation is for down, with gas to pass through direction identical, the electrolyte of impregnation not only moves under Action of Gravity Field down, and is pressed and move down by gas, therefore can residual electrolyte at the intake section of porous part, degassing function can not stop fully.That is, according to the present invention, play leakage when reducing battery and falling, also can utilize the superior like this effect of degassing function after recovering from falling.Especially in the battery on being equipped on two-wheeled vehicle, exist the in use temporary transient distinctive problem of falling that produces, lead accumulator of the present invention can be applicable to two-wheeled vehicle.And, also can use binding agent etc. that the part of porous part is fixed in the wall (comprise and form the wall of stream down) that forms described exhaust flow path.
Preferred described porous part is by the chimeric side wall inner surfaces that forms described stream down that is disposed at.Thus, only by porous part being embedded stream down, just porous part can be fixed in stream down, it be made simplify.
Stretch out to upside from described stream down the upper end of preferred described porous part.Thus, can from the top, porous part be pressed to stream down, can prevent that porous part from staggering upward.
Concrete shape as porous part, can consider that described porous part is the shape that attenuates along with passing through, by with described porous part from its another described stream down of distolateral insertion, thereby the outer surface of described porous part is embedded in the side wall inner surfaces that forms described stream down.For example, porous part is the rotary body shape that is continuously towards the below or interimly attenuates, as cone shape down, down truncated cone shape, connect different-diameter two columnar portion shape or have the shape etc. of these shapes in a part at least, the outer peripheral face that can consider porous part is contacted with the side wall inner surfaces that forms stream down and the shape that is fixed.Thus, owing to need not exhaust flow path being implemented special processing, just can be with the low cost fabrication lead accumulator.If especially the former three such simple shapes, can make the processing cost of porous part reduce.In addition, porous part can be also have the diameter larger than the stream diameter of stream down spherical.
In the situation that porous part is the shape that connects two columnar portion of different-diameter, preferred described porous part is made of minor diameter part and large-diameter portion, described minor diameter part is disposed at described stream down, and described large-diameter portion and this minor diameter part form continuously, and stretch out configuration from described stream down.
Preferred described stream down attenuates towards the below.For example can consider that stream down is be the taper of undergauge continuously towards the below or be the step-like of interim ground undergauge.Stream down with respect to being this stream shape can use columned parts as porous part.Therefore, the processing cost of porous part is reduced, can be with the low cost fabrication lead accumulator.In addition, in the situation that the inevitable withdrawing pattern tapering of forming when making down stream can effectively utilize it.
For the decrease material cost, described porous part preferably is rolled into the Porous sheet structure of coniform or circular cone shape.
Specifically, as being used for porous part is pressed to from the top concrete structure of stream down, preferred described electric groove lid has the middle cover that stops up described electric groove and the upper cover that is arranged on the top of this middle cover, described exhaust flow path is by consisting of with the groove of described upper cover obturation in the upper surface setting of described middle cover, and described porous part is pressed structure to downside by described upper cover under the state that is disposed at described stream down.Thus, the parts that can arrange in addition to press porous part just can prevent the dislocation of porous part, can be reliably fixing porous part.
As lead accumulator, the style of opening of liquid formula preferably.In such lead accumulator, more remarkable effect of the present invention.
In addition, preferred described lead accumulator is the battery that needs at least the non-non-maintaining type of additional electrolyte.The lead accumulator of non-non-maintaining type can be by making as anodal grid and negative pole grid with the Pb-Sb alloy.The Pb-Sb alloy is the alloy that contains at least plumbous and antimony, and the content of antimony is below the above 3 quality % of 1.5 quality %, is preferably below the above 3 quality % of 2 quality %.
Preferred described electric groove is divided into a plurality of monocells chambers, covers at described electric groove to be formed with a plurality of independent exhaustion mouths that arrange corresponding to described each monocell chamber, and described exhaust flow path is communicated in described a plurality of independent exhaustion mouth.Thus, need not porous part be set at each exhaust outlet, by single porous part is set at exhaust flow path, thereby can make the designs simplification of lead accumulator, and it is made simplify.
Preferred described electric groove is divided into a plurality of monocells chambers, cover at described electric groove and be formed with a plurality of liquid plugs and a plurality of independent exhaustion mouth that arranges corresponding to described each monocell chamber, described a plurality of liquid plugs and described a plurality of independent exhaustion mouth are arranged at mutually different position.Due to the independent exhaustion mouth by coverings such as upper covers, so in independent exhaustion mouth and liquid plug are integral and are in the structure of same position, exist fluid injection or the unfavorable condition in its fluid injection cost time that can't carry out electrolyte.For this reason, making independent exhaustion mouth and liquid plug is Split type structure, and is arranged on mutually different positions, thereby no matter whether cover the existence of the upper cover etc. of independent exhaustion mouth, can both operate liquid plug, can make the fluid injection simplified control of electrolyte.

One execution mode of the lead accumulator that the present invention relates to below with reference to description of drawings.
The lead accumulator 100 that present embodiment relates to uses on the motor vehicles such as two-wheeled vehicle such as carrying, and is the opening lead accumulator of liquid formula of whole (the 6 cell monoblock) type of 6 monocells.And, in the present embodiment, although 6 monocell monolithic deviceses are illustrated, also going in addition on 3 monocell monolithic deviceses etc., monocell quantity is not particularly limited.
Specifically, as Fig. 1～shown in Figure 3, it possesses: electric groove 2, and this electricity groove 2 is divided into six monocell chambers by five next doors of the configuration that is parallel to each other, and is roughly rectangular shape; And electric groove lid 3, this electricity groove lid 3 covers the upper opening of this electricity groove 2 and tabular in the form of a substantially rectangular.And, the electrolyte (not shown) that contains respectively pole plate group 4 and consisted of by dilute sulfuric acid in each monocell chamber of electric groove 2.Pole plate group 4 is through positive pole band and negative pole band (all not shown) and be electrically connected on the mechanism of positive terminal 5 and negative terminal 6, and is across dividing plate and the mechanism of stacked each polylith positive plate and negative plate.Positive plate is the mechanism for the positive active material that keeps being made of brown lead oxide on the anodal grid that is made of the Pb-Sb alloy, and negative plate is the mechanism for the negative electrode active material that keeps being made of lead on the negative pole grid that is made of the Pb-Sb alloy.At this, the content of the antimony in the Pb-Sb alloy is below the above 3 quality % of 1.5 quality %, is preferably below the above 3 quality % of 2 quality %.
And as Fig. 1～shown in Figure 3, exhaust flow path 3c has: the primary flow path 3c1 of linearity; It is connected in six independent exhaustion mouth 3b and extends along about the in-plane of electric groove lid 3; With the 3c2 of stream down of linearity, its end from this primary flow path 3c1 (being right-hand end Fig. 3) is vertical towards downward-extension.
The end (right-hand end) of primary flow path 3c1 is constituted as than electric groove 2 and stretches out more laterally, and stream 3c2 stretches out downwards from this right-hand end down.That is, stream 3c2 constitutes and is positioned at than electric groove 2 position more in the outer part down.And, this down the lower ending opening 3c3 of stream 3c2 will be discharged in the lump outside exhaust outlet (below, be called and gather exhaust outlet 3c3) (with reference to figure 1 and Fig. 3) down by the gas after exhaust flow path 3c for being used for.
The electric groove lid 3 of present embodiment as Fig. 1～shown in Figure 3, has: the tabular in the form of a substantially rectangular middle cover 31 that covers the upper opening of electric groove 2; And the upper cover 32 that is arranged on the upper surface of this middle cover 31.
Be formed with described six liquid injection port 3a and six liquid plugs 7 on middle cover 31; And six independent exhaustion mouth 3b that arrange in the position that is different from described liquid injection port 3a (liquid plug 7).Linearly being configured on left and right directions of six liquid injection port 3a (liquid plug 7), six independent exhaustion mouth 3b are linearly being configured on left and right directions also, and the orientation of six liquid injection port 3a (liquid plug 7) and six independent exhaustion mouth 3b are parallel to each other.
In addition, be formed with the groove 31M that extends along left and right directions on middle cover 31, be formed with described six independent exhaustion mouth 3b in the bottom surface of this groove 31M.
And then, on the side on the left and right directions of middle cover 31 (being the side, right side in Fig. 3), especially as shown in Figure 4, extend the forming portion of stream down 311 that is provided with the described 3c2 of stream down of formation.This down the upper surface of stream forming portion 311 be formed with the right-hand end of described groove 31M, and be formed with the through hole 311x of linearity in the mode to the bottom surface opening of the right-hand end of this groove 31M.The through hole 311x of this linearity forms the described 3c2 of stream down, and the open lower side of through hole 311x is the described exhaust outlet 3c3 that gathers.And the forming portion of stream down 311 of present embodiment is roughly L word shape in main apparent time, is formed with groove 31M at the upper surface of its L word horizontal part 311a, and 311b is formed with through hole 311x at L word vertical component effect.This through hole 311x is along with towards the below and the hole that is taper that flowing path section diminishes gradually continuously.
And, at the upper surface of the middle cover 31 that so consists of, wait by applying by hot melt in the mode that covers described groove 31M integral body the upper cover that bonds, thus an exhaust flow path 3c being communicated with six independent exhaustion mouth 3b of formation.And, down stream forming portion 311, specifically L word vertical component effect 311b for the connector of the soft outside pipe arrangements such as pipe (material is such as being polyvinyl chloride or polyethylene) is installed, installs this outside pipe arrangement by outer embedding and connects outside pipe arrangement.This outside pipe arrangement is for being released to outside mechanism from the home away from lead accumulator 100 from the gas that gathers exhaust outlet 3c3 discharge.
Then, in the lead accumulator 100 of present embodiment, especially as shown in Figure 4, be provided with porous part 8 on exhaust flow path 3c.This porous part 8 has acid mist contained in the gas of the discharge of removing and prevents the function of igniting from the outside, and have both be used to making the electrolyte that leaks from described independent exhaustion mouth 3b be difficult to flow out to the electrolyte of outside by described exhaust flow path 3c and flow out delay feature, it is such as the sintering of plastics porous plastid that is made of plastics such as the polypropylene with water proofing property, form such as the porous ceramic such as aluminium oxide or porous glass.
This porous part 8 is along with to the rotary body shape of the other end (being the lower end in Fig. 4) undergauge, being in the present embodiment cone shape from an end (being the upper end Fig. 4).And this porous part 8 is by being fixed in stream 3c2 down with its another distolateral insertion down from the top stream 3c2.At this moment, the outside circumference of the axial middle body of porous part 8 is embedded in and forms the upper end of the side wall inner surfaces of stream 3c2 (through hole 311x) down, the end portion of this porous part 8 is configured in down in stream 3c2, and the upper part of porous part 8 is stretched out and is configured in primary flow path 3c1 from stream 3c2 down.So, porous part 8 is set as and blocks the upper side opening of stream 3c2 (through hole 311x) down.
As mentioned above by at the configuration of stream 3c2 down porous part 8, thus make porous part 8 gas pass through direction down.And porous part and the outlet of stream 3c2 down namely gather exhaust outlet 3c3 and are configured in turn the position relationship of up and down along vertical direction.By forming such position relationship, even impregnation electrolyte in porous part 8, the moving direction of the electrolyte of this impregnation is for down, with gas to pass through direction identical, the electrolyte of impregnation not only moves under Action of Gravity Field down, and pressed and move down by gas, therefore can residual electrolyte at the intake section of porous part 8, degassing function can not stop fully.
And, in existing lead accumulator, the porous part that consists of filter be configured to gas in this porous part by direction for up or be towards laterally.So, in the situation that the porous part of configuration contains the electrolyte that spills, this porous part occurs to stop up and inaccessible by electrolyte.Therefore in the scope of prior art, normally porous part is arranged on not with position that the electrolyte that spills contacts on.Therefore, can't expect at all that from prior art present embodiment configures the design of porous part 8 like that in the position that contacts with electrolyte, especially fail to give attention to porous part 8 and gather the such structure of position relationship that exhaust outlet 3c3 is configured to the up and down in turn.
As the installation method of this porous part 8, make before upper cover 32 is bonded to middle cover 31, the upper side opening of the through hole 311x of stream forming portion 311 embeds porous part 8 porous part 8 is installed down, then makes upper cover 32 be bonded in middle cover 31.Thus, form electric groove lid 3, and the primary flow path 3c1 that is communicated with a plurality of independent exhaustion mouth 3b of formation and the 3c2 of stream down of the extension from this primary flow path 3c1 to downside, become simultaneously at this structure of porous part 8 is set on stream 3c2 down.So, only by porous part 8 is embedded the through hole 311x of stream forming portion 311 down from the top, just can porous part 8 be set stream 3c2 down, thereby the installation of porous part 8 is simplified, and the manufacturing of lead accumulator 100 is simplified.
Lead accumulator 100 according to the present embodiment of such formation, at least a portion due to configuration porous part 8 in the 3c2 of stream down of exhaust flow path 3c, electrolyte escapes to the speed of outside batteries from exhaust flow path 3c so slow down, and can suppress electrolyte and escape to outside batteries by exhaust flow path 3c.
In addition, lead accumulator 100 according to present embodiment, be disposed at because porous part 8 is chimeric and form the side wall inner surfaces of stream 3c2 down, so porous part 8 can be simplified with respect to the contraposition of stream 3c2 down, and can reliable placement porous part 8, even the mechanism that is used for fixing porous part 8, the dislocation that yet is difficult to produce porous part 8 are not set in addition.Especially can prevent reliably that porous part 8 from misplacing in stream 3c2 down downwards.
And then, lead accumulator 100 according to present embodiment, due to just at the 3c2 of stream down of the exhaust flow path 3c porous part 8 of packing into, so need not change the design of existing lead accumulator, can apply flexibly the structure of existing lead accumulator and make the configuration of porous part 8 simple and reliable, and can simplify the manufacturing of lead accumulator 100.
In addition, lead accumulator 100 according to present embodiment, in porous part 8 gas by direction for down, even impregnation electrolyte in porous part 8, the moving direction of the electrolyte of this impregnation is for down, with gas to pass through direction identical, the electrolyte of impregnation not only moves under Action of Gravity Field down, and pressed and move down by gas, therefore can residual electrolyte at the intake section of porous part 8, degassing function can not stop fully.That is, according to the lead accumulator 100 of present embodiment, play the leakage when reducing battery 100 and falling, also make the degassing function can be with so superior effect after recovering from falling.
Need to prove, the invention is not restricted to described execution mode.
For example shown in Figure 5, be configured at the porous part 8 of described execution mode under the state of stream 3c2 down, the upper surface that also can constitute porous part 8 contacts and is pressed to downside with the lower surface of upper cover 32.Like this, porous part 8 can not stagger upward, and porous part 8 is pressed towards stream 3c2 down, thus can be reliably fixing porous part 8.
In addition, as shown in Figure 6, also can constitute stream 3c2 (through hole 311x) down upper side opening, be that the bottom surface of groove 31M and the upper surface of porous part 8 become same.
And then, as shown in Figure 7, also can constitute porous part 8 is embedded stream 3c2 (through hole 311x) down.At this moment, porous part 8 can constitute: porous part 8 has the shape identical with the inner surface of described through hole 311x, and the roughly whole contact of its outside circumference is embedded in the interior lateral circle surface of through hole 311x.
In addition, as shown in Figure 8, porous part 8 also can be made of minor diameter part 81 and large-diameter portion 82, and minor diameter part 81 is disposed at down in stream 3c2, large-diameter portion 82 and this minor diameter part 81 form continuously, and stretch out and be disposed in primary flow path 3c1 from the described 3c2 of stream down.At this moment, the lower surface of large-diameter portion 82 contacts and is limited to the bottom surface of the groove 31M of the opening edge that forms stream 3c2 down.In addition, as shown in Figure 9, minor diameter part 81 can be also to be embedded in the shape of stream 3c2 down, and as shown in figure 10, the upper surface that also can constitute large-diameter portion 82 is pressed to downside by the lower surface of upper cover 32.
In addition, as shown in figure 11, stream 3c2 can be the step-like structure that is interim undergauge towards the below down.And Figure 11 is illustrative is to be this two step-like example of large pathway 3c21 and path road 3c22.At this moment, can consider to configure roughly columned porous part 8 in large pathway 3c21.
And then, in addition as shown in figure 12, also can constitute the chimeric spot-facing 311z of section that is installed in the upside peristome formation of through hole 311x of porous part 8.At this moment, as the shape of porous part 8, for example can consider circular plate shape.
In addition, in said embodiment, because stream 3c2 down is taper, therefore also can use to have to be stuck in this roughly columned porous part 8 of the diameter in stream down.And porous part 8 can be by being rolled into the Porous sheet coniform or circular cone shape is made conical shaped shape or truncated cone shape roughly.If this structure can reduce the processing cost of porous part 8, can be with the low cost fabrication lead accumulator.
In addition, although the stream down of described execution mode is that stream can be also towards oblique below down towards vertical downward.As the shape of stream down, except linearity, can be also crooked shape or the shape of flexing.
In addition, although the forming portion of stream down of described execution mode is roughly L word shape, the shape of stream gets final product so long as can form down in addition, can be to form the right-hand end of groove 31M at upper surface, is formed with the jut of through hole 311x in inside.
In addition, in said embodiment, although by an exhaust flow path to the exhaust in the lump of a plurality of independent exhaustion mouths, but can carry out exhaust by plural exhaust flow path, also can exhaust flow path be set at each independent exhaustion mouth, this each exhaust flow path as described execution mode porous part is set like that.
In addition, the present application can be applied to motor vehicle with this lead accumulator, especially is preferably applied to two-wheeled vehicle.
In addition, the present invention can the described execution mode of appropriate combination or part or all of distortion execution mode, can carry out various changes in the scope that does not break away from its purport.
