And like 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 along about the in-plane of electric groove lid 3, extends; With the 3c2 of stream down of linearity, its end from this primary flow path 3c1 (being right-hand end Fig. 3) vertical court extends below.
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 be used for be discharged to outside exhaust outlet (below, be called and gather exhaust outlet 3c3) (with reference to figure 1 and Fig. 3) in the lump down through the gas behind the exhaust flow path 3c.
The electric groove lid 3 of this execution mode like 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 loam cake 32 that is arranged on the upper surface of this middle cover 31.
On middle cover 31, be formed with said six liquid injection port 3a and six liquid plugs 7; And six independent exhaustion mouth 3b that are provided with in the position that is different from said liquid injection port 3a (liquid plug 7).Six liquid injection port 3a (liquid plug 7) linearly shape are configured on the left and right directions, six independent exhaustion mouth 3b also linearly shape be configured on the left and right directions, the orientation of six liquid injection port 3a (liquid plug 7) and six independent exhaustion mouth 3b are parallel to each other.
In addition, on middle cover 31, be formed with the groove 31M that extends along left and right directions, be formed with said six independent exhaustion mouth 3b in the bottom surface of this groove 31M.
And then, especially as shown in Figure 4 on the side on the left and right directions of middle cover 31 (being the side, right side among Fig. 3), extend the formation of the stream down portion 311 that forms the said 3c2 of stream down that is provided with.Be formed with the right-hand end of said groove 31M at the upper surface of this portion of stream formation down 311, and be formed with the through hole 311x of linearity with mode to the bottom surface opening of the right-hand end of this groove 31M.The through hole 311x of this linearity forms the said 3c2 of stream down, and the open lower side of through hole 311x is the said exhaust outlet 3c3 that gathers.And the formation of the stream down portion 311 of this execution mode 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 constitutes,, form an exhaust flow path 3c who is communicated with six independent exhaustion mouth 3b thus through to cover the whole mode of said groove 31M through the deposited bonding loam cake that waits of hot melt.And the portion of stream formation down 311, specifically L word vertical component effect 311b installs and should connect outside pipe arrangement by the outside pipe arrangement through outer embedding for the connector of soft pipe outside pipe arrangements such as (material for example are polyvinyl chloride or polyethylene) is installed.This outside pipe arrangement is to be used for being released to outside mechanism from the gas that gathers exhaust outlet 3c3 discharge from the home away from lead accumulator 100.
Then, especially as shown in Figure 4 in the lead accumulator 100 of this execution mode, on exhaust flow path 3c, be provided with porous part 8.This porous part 8 has the acid mist that is contained in the gas of the discharge of removing and prevents the function of igniting from the outside; And have both and be used to make the electrolyte that leaks from said independent exhaustion mouth 3b to be difficult to flow out delay feature through the electrolyte that said exhaust flow path 3c flows out to the outside, it is for example formed by porous ceramic such as sintering of plastics porous plastid that plastics such as the polypropylene with water proofing property constituted, for example 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 among Fig. 4) undergauge, in this execution mode, being cone shape from an end (being the upper end Fig. 4).And this porous part 8 is through being fixed in stream 3c2 down with its another distolateral insertion down from the top the 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 the stream 3c2, and the upper part of porous part 8 is stretched out and is configured in the primary flow path 3c1 from stream 3c2 down.So, porous part 8 is set as and blocks the last side opening of stream 3c2 (through hole 311x) down.
As stated through at the configuration of stream 3c2 down porous part 8, thus make porous part 8 gas direction of passage down.And porous part and the outlet of stream 3c2 down promptly gather exhaust outlet 3c3 and are configured to position relation up and down along vertical direction in order.Through forming such position relation; Even impregnation electrolyte in porous part 8, the moving direction of the electrolyte of this impregnation are identical with the direction of passage of gas for down; The electrolyte of impregnation not only moves under action of gravity down; And pushed 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 direction of passage that the porous part that constitutes filter is configured to gas in this porous part is for up or for towards horizontal.So, contain under the situation of the electrolyte that spills at the porous part of configuration, this porous part takes place to stop up and inaccessible by electrolyte.Therefore in the scope of prior art, normally with porous part be arranged on not with the electrolyte position contacting that spills on.Therefore, from prior art can't expect at all this execution mode that kind with the design of electrolyte position contacting configuration porous part 8, especially unexpected with porous part 8 with gather exhaust outlet 3c3 and be configured to the such structure of position relation up and down in order.
As the installation method of this porous part 8, make before loam cake 32 is bonded to middle cover 31, down the through hole 311x of stream formation portion 311 on side opening embed porous part 8 porous part 8 be installed, make loam cake 32 be bonded in middle cover 31 then.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, become the structure that porous part 8 is set on the stream 3c2 at this simultaneously down from the 3c2 of stream down of this primary flow path 3c1 to the downside extension.So, only, just can porous part 8 be set stream 3c2, thereby the installation of porous part 8 is simplified, and the manufacturing of lead accumulator 100 is simplified down through porous part 8 is embedded the through hole 311x of the portion of stream formation down 311 from the top.
Lead accumulator 100 according to this execution mode of such formation; Because at least a portion of configuration porous part 8 in the 3c2 of stream down of exhaust flow path 3c; Electrolyte can suppress electrolyte and escape to outside batteries through exhaust flow path 3c from the speed that exhaust flow path 3c escapes to outside batteries so slow down.
In addition; Lead accumulator 100 according to this execution mode; Because porous part 8 chimeric being disposed at form the side wall inner surfaces of stream 3c2 down,, and can reliably dispose porous part 8 so porous part 8 can be simplified with respect to the contraposition of stream 3c2 down; 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 the stream 3c2 down downwards.
And then; Lead accumulator 100 according to this execution mode; Because 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, according to the lead accumulator 100 of this execution mode, the direction of passage of gas is for down in the porous part 8; Even impregnation electrolyte in porous part 8, the moving direction of the electrolyte of this impregnation are identical with the direction of passage of gas for down; The electrolyte of impregnation not only moves under action of gravity down; And pushed 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,, play the leakage when reducing battery 100 and falling, after recovering, also make degassing function can use so superior effect from falling according to the lead accumulator 100 of this execution mode.
Need to prove that the utility model is not limited to said execution mode.
For example shown in Figure 5, be configured at the porous part 8 of said execution mode under the state of stream 3c2 down, the upper surface that also can constitute porous part 8 contacts with the lower surface of loam cake 32 and is pressed to downside.Like this, porous part 8 can not stagger to the top, and porous part 8 is pressed towards stream 3c2 down, thereby can secure fixation porous part 8.
In addition, as shown in Figure 6, also can constitute stream 3c2 (through hole 311x) down last 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 said 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 up of minor diameter part 81 and large-diameter portion 82, and minor diameter part 81 is disposed at down in the stream 3c2; Large-diameter portion 82 forms with this minor diameter part 81 continuously, and stretches out and be disposed in the primary flow path 3c1 from the said 3c2 of stream down.At this moment, the lower surface of large-diameter portion 82 contacts and is limited to and forms the bottom surface of the groove 31M of the opening edge portion of stream 3c2 down.In addition, as shown in Figure 9, minor diameter part 81 also can be to be embedded in the shape of stream 3c2 down, and is shown in figure 10, and the upper surface that also can constitute large-diameter portion 82 is pushed to downside by the lower surface of loam cake 32.
In addition, 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 to be to be this two step-like example of big pathway 3c21 and path road 3c22.At this moment, can consider the roughly columned porous part 8 of configuration in big pathway 3c21.
And then, shown in figure 12 in addition, also can constitute the porous part 8 chimeric 311z of spot-facing portion that are installed in the upside peristome formation of through hole 311x.At this moment, as the shape of porous part 8, for example can consider circular plate shape.
Therefore in addition, in said execution mode,, also can use to have to be stuck in this roughly columned porous part 8 of the diameter in the stream down because stream 3c2 is taper down.And porous part 8 can be through being rolled into porous matter sheet coniform or circular cone shape is processed conical shaped shape or truncated cone shape roughly.If this structure can reduce the processing cost of porous part 8, can make lead accumulator with low cost.
In addition, though the stream down of said execution mode is that stream also can be towards oblique below down towards vertical downward.As the shape of stream down, except linearity, also can be the crooked shape or the shape of flexing.
In addition, though the formation of the stream down portion of said execution mode is roughly L word shape, the shape of stream gets final product so long as can form down in addition, can be the right-hand end that forms groove 31M at upper surface, is formed with the jut of through hole 311x in inside.
In addition; In said execution mode; Though 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, as said execution mode, porous part is set at this each exhaust flow path at each independent exhaustion mouth.
In addition, the application's utility model can be applied to motor vehicle with this lead accumulator, especially is preferably applied to two-wheeled vehicle.
