Embodiment

Be elaborated to of the present utility model referring to accompanying drawing.

First, describe the detailed structure of general existing lead accumulator in detail according to Fig. 1 to Fig. 3.

Fig. 1 is the overall perspective view of existing lead accumulator 100, and in Fig. 1, lead accumulator 100 is in being conventionally mounted the common use state that uses or charge.In the following description, related direction is taking this common use state as benchmark.Fig. 2 is the vertical view of existing lead accumulator 100.Fig. 3 is the cutaway view along the A-A line of Fig. 2.

In Fig. 1, illustrated lead accumulator 100 is to be equipped on the lead accumulator 100 using on motorcycle.The related lead accumulator of the utility model is that 10 hour rate discharge capacities are below the above 13Ah of 3.8Ah, is preferably below the above 13Ah of 5Ah, more preferably below the above 12Ah of 5Ah.

As shown in FIG. 1 to 3, lead accumulator 100 mainly comprises the electric groove 10 that is roughly the open box of a side, is contained in the battery unit 20 in electric groove 10 and covers the electric groove lid 30 of a side of the opening of electric groove 10.Wherein the inner space of electric groove 10 is divided into six receiving spaces that are arranged in a row (battery chamber), contains respectively a battery unit 20 in each receiving space.The length (sizes in battery unit 20 orientations) of the battery chamber of the related lead accumulator 100 of the utility model is about below the above 45mm of 15mm, is preferably below 30mm.Each battery unit 20 comprises by positive plate, negative plate and Jie and is battery lead plate (not shown) that the dividing plate between positive plate and negative plate is laminated repeatedly, the respectively sub-terminal of positive and negative electrode (not shown) that conducts with the both positive and negative polarity of positive plate and negative plate conducting and the electrolyte (not shown) that is filled in the working solution as battery unit 20 in receiving space.In addition, lead accumulator unit 100 also have respectively with the positive terminal 50 of the sub-terminal conducting of positive pole of each battery unit 20 and respectively with the negative terminal 60 of the sub-terminal conducting of negative pole of each battery unit 20.Positive plate for example can form by adhering to or fill as the brown lead oxide of positive active material on the alloy grid at Pb-Sb, and negative plate for example can form by adhering to or fill as the lead of negative electrode active material on the alloy grid at Pb-Sb.That is to say, lead accumulator 100 is opening lead accumulators of six haplotypes.

Here, the battery unit number of accommodating in electric groove is not limited to six, can be also one or more.In addition, the receiving space of each battery unit is also not limited to be arranged in a row, and also can be arranged as many rows.In addition, for the material of the battery pole plates in battery unit and the formation of structure and electrolyte etc., being not particularly limited, can be the various possible formation in this area.

After electric groove lid 30 being covered to electric groove 10 here, be called medial surface towards a side of battery unit, and by with medial surface mutually on the contrary outward a side on boundary be called lateral surface.As shown in FIG. 1 to 3, the lid main body 32 of electric groove lid 30 is the rectangle roughly the same with the shape of the open sides of electric groove 10.Be formed with in main body 32 and each battery unit 20 corresponding six liquid injection hole 32a respectively at lid, each liquid injection hole 32a respectively with each receiving space of electric groove 10 together with, can in each receiving space, inject electrolyte by each liquid injection hole 32a thus.On each liquid injection hole 32a, be separately installed with the plunger 34 that blocks liquid injection hole 32a from the lateral surface of lid main body 32.In addition, in lid main body 32, be also formed with the terminal hole 32c that makes respectively positive terminal 50 and negative terminal 60 expose.And also correspond respectively to positive terminal 50 in main body 32 and negative terminal 60 marks have polarity mark 32e at lid.

As shown in Figure 3, on electric groove lid 30, also form exhaust channel, be discharged outside to for the gas that the use at battery or charging process are produced.The width (perpendicular to the orientation of battery unit 20) of the exhaust channel of the related lead accumulator 100 of the utility model is below the above 9mm of 4mm.Exhaust channel by the discharge currents of gas to comprising successively downstream the introducing cylinder portion 36 that corresponds respectively to each battery unit 20 and form from upstream, each introducing cylinder portion 36 being communicated with to the primary flow path 37 of getting up and the gas in primary flow path 37 is exported to extraneous export cylinder portion 38.As shown in Figure 3, this primary flow path 37 is communicated with each battery unit 20 of lead accumulator 100 via each introducing cylinder portion 36.Introducing cylinder portion 36 is formed on the medial surface that covers main body 32, be roughly along with vertical hollow cylindric of lid main body 32.The lower end of introducing cylinder portion 36 is toward battery unit 20 openings, and the upper end open of introducing cylinder portion 36 is in the lateral surface of lid main body 32 and the conglobate introducing port 36b of shape.But might not be circular, can arrange arbitrarily.The diameter of the introducing port 36b of the related lead accumulator 100 of the utility model when non-circular (be the size of the Width of exhaust channel), for below the above 10mm of 2mm, is preferably below the above 6mm of 3mm.

On the lateral surface of lid main body 32, be formed with the groove 37a that each introducing port 36b is communicated with, and on this groove 37a, be provided with the not removable upper cover 39 of this groove of sealing 37a, thereby surrounded primary flow path 37 by groove 37a and upper cover 39.Primary flow path 37 by such formation of structure sealing prevents that gas from leaking from primary flow path 37.,, for the non-maintaining type lead accumulator without in use supplementing electrolyte, after first fluid injection, upper cover 39 is bonded on groove 37a.

In addition, be formed with as the export cylinder portion 38 that gas is exported to outside gas leading-out portion at the end of exhaust channel.For the ease of forming export cylinder portion 38, the mode that primary flow path 37 is stretched out from one end (right-hand end Fig. 1～Fig. 3) of lid main body 32 with the length direction along primary flow path 37 forms.Export cylinder portion 38 is formed in mode down on the bottom surface of extension of this primary flow path 37.The hollow circle tube that export cylinder portion 38 is downwardly facing opening, one end of downwardly facing opening forms outlet 38a.Here, outlet 38a is preferably the below towards gravity direction.But the utility model is not limited to this, can make outlet 38a court with respect to the acclivitous direction of horizontal direction, horizontal direction or the court direction downward-sloping with respect to horizontal direction.

In addition, the gas that battery unit 20 produces, is directed into primary flow path 37 from introducing port 36b, and is discharged to the external world through primary flow path 37 through outlet 38a, so forms the flow channel (exhaust channel) of gas.Below, the outlet 38a side of exhaust channel is referred to as to downstream.When gas sprays from introducing port, can carry a part of electrolyte acid mist secretly and flow in the lump in exhaust channel, these acid mists will arrive the porous part 80 being arranged in export cylinder portion 38 with gas.But even if be provided with to filter the porous part 80 of acid mist, also inevitably some acid mist can ooze out from porous part 80, drops onto the outside of battery with drop form.This situation, along with the increase meeting of the service time of battery is more serious, even can erode the equipment of outside batteries.In addition, along with the loss of electrolyte, for cannot injecting the non-maintaining type storage battery of electrolyte, representing the shortening in useful life.

By Fig. 4 to Fig. 7, the concrete structure of the utility model first to the 3rd execution mode is described below.

< the first execution mode >

Fig. 4 is the vertical view of the lead accumulator of the utility model the first execution mode, and Fig. 5 is the profile along the A-A line of Fig. 4, amplifies and has shown the residing part in next door.As shown in Figure 4 and Figure 5, in the primary flow path 37 of exhaust channel, be formed with next door 37b in the downstream of introducing port 36b.The downstream of each introducing port 36b all can arrange next door, also can be only at 1 formation next door, place 37b.That is to say, the magnitude setting of next door 37b is at least 1.In present embodiment, be provided with 3 next door 37b.

In present embodiment, next door 37b is erectly fixed on and is covered in main body 32.; in the common use state of storage battery 100 as shown in Figure 1; next door 37b is formed at the below of the short transverse of primary flow path 37; and the space that supplied gas is passed through is left in the top of next door 37b; and in the Width (direction vertical with the orientation of each battery chamber in Fig. 4 of the primary flow path 37 of exhaust channel;, Fig. 4 along paper left and right directions) upper across whole primary flow path 37.That is to say, primary flow path 37 is except gap, and by next door, 37b fills up.

When battery operated, the mixture of the gas producing from battery unit 20 and electrolyte acid mist, can flow into primary flow path 37 from introducing port 36b.Flow into the mixture in primary flow path 37, can strike on the 37b of next door, gas can upwards flow to gap location after shock along next door, behind gap, continue side flow downstream, and most of acid mist can clash into deceleration and condense into drop in next door place, after drop reaches a certain size, because flowing downward, gravity is back in battery chamber through introducing port 36b.

Inventor of the present utility model finds, the setting position of next door 37b, and next door 37b, to the distance H of corresponding introducing port 36b, is the key factor that affects acid-mist seepage and the acid mist rate of recovery.

By form, the impact that next door 37b shines drop backflow of the present utility model to the distance H of introducing port 36b is described below.

The impact of table 1 next door backflow of the acid mist drops on different sizes to the distance of introducing port

Table 1 is for showing the impact of next door 37b rate of recovery of the drop on various diameters to the distance H of introducing port 36b.Wherein, "○" represents total reflux, and " △ " represents partial reflux; " x " indicates without refluxing.Liquid-drop diameter refers to that acid mist condenses into the diameter after drop.The diameter of the drop that the drop of 1mm-2mm scope can condense while normally discharging and recharging work for storage battery.And the diameter of the drop that can condense of 2mm during above for non-normal working.

Wherein, the acid mist forming when normal work can more efficiently be stopped by porous part 80 (porous part 80 will filter mainly for these drops), and (cross and discharge and recharge) a large amount of acid mists that form when non-normal working, be the main reason of shining into acid mist seepage.As can be known from the above table, when distance H is below 2.5mm time, the larger drop condensing can make non-normal working time refluxes, thereby can play the effect that reduces acid mist seepage.And distance H is less, the backflow effect playing can become large.Therefore, preferred distance H is below 2mm, now, the drop producing not only can reclaim all non-normal workings time, the larger drop can also be to normal work time reclaims, and further reduces the burden to porous part 80.

But, in plastics molding process, below distance H is less than 0.5mm time, can shine into obvious finished product shrink phenomenon, be unfavorable for rate of finished products, and, likely according to becoming 37b part in next door to stop introducing port 36b, cause the less introducing port 36b of 2mm degree to be stopped up by drop, shine into cell internal pressure and raise, produce the problems such as abnormal sound.Further, preferred distance H is more than 1mm, now not only can reclaim well the drop of all sizes, the bad phenomenon such as shrink can also avoid plastic shaping completely time, improve yields, and prevent the variety of issue causing compared with large drop obstruction introducing port 36b.

In addition, inventor of the present utility model also finds, the area (evaluating with the height h in next door) that stops in the area (due to the constant width of exhaust channel, therefore evaluating with the height S in gap) in gap and next door also can reflux and shine into impact with drop acid-mist seepage.And the height S in gap on the impact of storage battery mainly from the impact of the circulation on gas.And the height h in next door is the barrier effect to drop on the impact of storage battery.

Find through experiment, when the height S in gap is 0.3mm below time, adopt general ultrasonic fusing technique when covering fixing that body 32 and upper cover 39 carry out, because needs apply external force, can have the problems such as next door deforms, cannot guarantee required various sizes.Therefore the height S in gap, says from technological angle, more than should be 0.3mm.And when the height S in gap be 0.5mm when above, can guarantee to make precision, therefore comparatively preferred.But when the height S in gap is less than 1mm, likely there is the not enough problem in gas communication space (breathing area).Therefore, from considering breathing area, reduce the viewpoint of storage battery internal gas pressure and set out, the height S in preferred gap is more than 1mm.

In addition, for the height h in gap, the drop size forming during due to normal work is in 2mm, and therefore, the height h in gap at least will be more than 2mm.Further, the larger drop (2mm to 2.75mm) forming when preventing non-normal working, is preferably below the above 3.5mm of 2.5mm.In the time exceeding 3.5mm, for lead acid battery for motorcycle, because the height of exhaust channel is limited, likely cannot reserve enough gaps.

According to the lead accumulator of above-mentioned the first execution mode, be provided with next door 37b in the downstream of introducing port 36b, and the setting position of counter septum 37b and size have been carried out research with keen determination, compare existing lead accumulator and can greatly reduce acid mist leakage problems, and by reclaiming electrolyte acid mist, extend the useful life of storage battery.

In addition, in the time that multiple next door 37b is set, the parameter of next door 37b (H, h, s) can be made as to a steady state value, convenient manufacture.But 38a(consults Fig. 3 due to outlet) be arranged on one end of exhaust channel, therefore, according to the distance from outlet 38a, the gas flow in exhaust channel and acid mist amount can increase progressively.Distance is nearer, and acid mist will be more.According to this feature, can suitably adjust the parameter of next door 37b, acid mist is condensed reclaim to reach maximization.For example, can, from away from the next door 37b of outlet 38a side, successively increase progressively the height h in next door, and reduce the height s in gap, thereby improve the acid mist rate of recovery of condensing, and suitably increase gradually distance H and deal with the droplet size increasing gradually.

< the second execution mode >

Fig. 6 is the profile of the exhaust channel of the utility model the second execution mode.As shown in Figure 6, be only that from the difference of above-mentioned the first execution mode the direction of next door 37c is different.The next door 37c of present embodiment is erectly fixed on upper cover 39.; in the common use state of storage battery 100 as described in Figure 1; next door 37c is formed at the top of the short transverse of primary flow path 37; and the space that supplied gas is passed through is left in the below of next door 37c, and upper across whole primary flow path 37 at the Width (direction vertical with the orientation of each battery chamber) of the primary flow path 37 of exhaust channel.

The next door 37c of present embodiment is at least formed on the downstream of the introducing port 36b of the most close porous part 80.Due to the formation space, below of next door 37c, therefore, stopped by porous part 80 and the drop piled up, can be back to battery chamber from space.Thus, can greatly alleviate the accumulation burden at porous part 80 places, make porous part 80 can keep good aeration status, be conducive to the discharge of gas, ensure the stable of accumulator internal pressure.

Further, by the next door 37c of multiple present embodiments is set, can make acid mist in flowing, meet next door 37c and slow down and condense, also can reach the minimizing acid mist seepage identical with the first execution mode, improve the effect that electrolyte reclaims.

The next door 37c of present embodiment is to the distance H of introducing port, and the height h in next door and the height S in gap, all can be identical with the first execution mode, and therefore it will not go into details.

< the 3rd execution mode >

Fig. 7 is the profile of the exhaust channel of the utility model the 3rd execution mode.As shown in Figure 7, present embodiment is the combination of the first execution mode and the second execution mode.In present embodiment, be mutually alternately provided with the next door 37b of multiple the first execution modes and the next door 37c of the second execution mode.Therefore, present embodiment not only possesses outside the advantage of above-mentioned two kinds of execution modes, owing to having extended the stream of gas in exhaust channel, thereby increase droplets agglomerate rate, further improve the drop rate of recovery, thereby further reduce the burden that drop shines porous part 80, greatly reduced the possibility that drop oozes out from porous part 80, thereby almost stopped the problem of the seepage of acid mist.

Further, in present embodiment, next door is to the distance H of introducing port, and the height h in next door and the height S in gap all can be identical with the first execution mode, and therefore it will not go into details.But the arrangement mode of next door 37b and next door 37c, is not limited only to alternative expression and arranges, and can carry out combination in any, but the most close preferred outlet 38a place arranges the next door 37c of the second execution mode.
