KDČIŠTE ZA INDUSTRIJSKE AKLMUIATORSKE BATERIJEKDCHI FOR INDUSTRIAL ACCUMULATOR BATTERIES
CBIAST TEHNIKECBIAST TECHNIQUES
Pronalazak' šire’posmatrano spada u oblast sredstava za direktno pretvaranje hemijske energije u električnu - akumulatora i njegovih konstrukcijskih delava. Pronalazak se posebno odnosi na konstrukciju kučišta akumulatora izradjenog od termoplastičnog materijala, primenljivcg za industrijske akumulatorske baterije ko je se naročite koriste za električnu vuču. Prema Medjunarodnoj klasifikaciji patenata pronalasku pripada oznaka H 01M 2/02.The invention 'broadly' falls within the scope of means for the direct conversion of chemical energy into electrical energy - the battery and its structural parts. The invention particularly relates to the construction of a battery housing made of thermoplastic material, applicable to industrial rechargeable batteries, which are specifically used for electric traction. According to the International Patent Classification, the invention belongs to code H 01M 2/02.
TEHNIČKI PROBLEMTECHNICAL PROBLEM
Tehnički problem ko ji se pronalaskan rešava sestoji se u teme da se poveča energetski potenci j al akumulatora povečanjem zapremine elektrolita bez premene spoljnih gabaritnih dimenzija kučišta, a da se pri tem izbegnu defoimacije zidova kučišta pod dejstvom hidrostatičkog pritiska elektrolita.The technical problem to be solved is to increase the energy potential of the battery by increasing the volume of the electrolyte without altering the outer dimensions of the housing, while avoiding the defocusing of the walls of the housing under the influence of the hydrostatic pressure of the electrolyte.
STANJE TEHNIKEBACKGROUND OF THE INVENTION
Akumulatorske baterije za industrijski upotrebu (električna vuča i sl.) se proizvode sa prepisanim spoljnim. dimenzijama prema medjunarodnim standardima. Ukoliko se želi povečanje električnog kapaciteta akumulatorske baterije povečanjan korisne zapremine koju zauzima elektrolit, to se mora postiči tako što če se zadržati spol j ne dimenzije odredjene medjunarodnim prepisima.Rechargeable batteries for industrial use (electric traction, etc.) are manufactured with prescribed external ones. dimensions according to international standards. If an increase in the electric capacity of a rechargeable battery is to be increased by increasing the usable volume occupied by the electrolyte, this must be achieved by maintaining the gender dimension determined by international regulations.
Jedan od načina ko j im se postiže povečanje zapremine elektrolita u okviru utvrd jenih gabaritnih mera jeste smanjenje debljine zidova kučišta akumulator skih baterija.One of the ways they can achieve an increase in the volume of electrolytes within the established dimensions is to reduce the thickness of the walls of the casing of the rechargeable batteries.
Ta se debljina, medjutim, može smanjiti samo do odredjene granice koju diktira otpomost primenjenog materijala, ispod ko j e hidros ta tički pritisak elektrolita izaziva deformacije zidova kučišta.However, this thickness can only be reduced to a certain extent dictated by the resistance of the applied material, below which the hydrolytic pressure of the electrolyte causes deformation of the casing walls.
Pored toga, mora se izbeči da veza ostvarena izmedju bočnih zidova kučiš ta i poklopca akumulatora dovede do ispupčenih profila, j er bi u ton slučaju svako smanjenje debljine zidova bilo beskorisno.In addition, it must be avoided that the connection between the side walls of the housing and the battery cover leads to protruding profiles, since in any case, any reduction in wall thickness would be useless.
Prema američkcm patentnem spisu br. 3,993,507 od 23 novembra 1976 godine, ko ji se odnosi na kučišta akumulatorskih baterija velikih dužina, u cilju izbegavanja deformacija zidova kučišta predvidjeno je više spoljnih poprečnih rebrastih ispusta izvedenih poobimu kučišta. Ova rebra primaju opterečenje usled hidrostatičkog pritiska elektrolita. U ovon slučaju je, pošto se rebra pruzaju po spol j noj strani kučišta, potrebno ostati u granicama odred j enim medjunarodnim standardima, što neminovno dovodi do smanjenja korisne zaeremine elektrolita u akumulatorskoj bateriji.According to U.S. Pat. No. 3,993,507 of November 23, 1976, which relates to long battery housing enclosures, in order to avoid deformation of the enclosure walls, a plurality of external transverse rib discharges are provided for each enclosure. These ribs receive a load due to the hydrostatic pressure of the electrolyte. In this case, since the ribs extend along the outer side of the housing, it is necessary to stay within the limits of certain international standards, which inevitably leads to a reduction of the useful volume of electrolytes in the battery.
Što se tiče veze izmed ju poklopca-1 kučištalreterige^ .da hi .se izbeglo povečanje ukupnih dimenzija kučišta, poznata tehnika predvidja zavarivanje sa gornje Strane ugaonog spoja izmedju poklopca izvedenog sa ravnim Ivicama, i odgovarajučih ivica bočnih stranica kučišta.With regard to the connection between the lid-1 housing and the housing. ^ To avoid increasing the overall dimensions of the housing, the known technique provides for welding from the upper side of the angular joint between the cover made with straight edges, and the corresponding edges of the sides of the housing.
Ova j način zavarivanja dovodi do obrazovanja spoljneg šava, koji se zatira mora obradjivati delimičnim skidanjem materijala/hako himse-ostalo -onntar standardnih ukupnih dimenzija.This method of welding leads to the formation of an outer seam, which must be machined by partial removal of the material / hako himse-other -ntar of the standard overall dimensions.
Medjutim, ova j postupak ima dva nedostatka. Prvi nedostatak je to što naknadna operacija obrade šava predstavlja -dodatni -fcrošak u-proizvodnji. Drugi je nedostatak to što se kod ove obrade šava skidanjen materijala mogu otvoriti vazdušni mehuriči zaostali u samem materijalu, što može da ugrozi zaptivenost spoja poklopca i kučišta. Takodje je meguča pojava -curenja -elektrolita, usled poroznosti šava. Ovime se otežava autanatsko dopunjavanje elektrolita, odn. autanatska regulacija nivoa elektrolita koja se bazira na padu ili porastu pritiska u akumulatoru u toku same eksploatacije.However, this procedure has two disadvantages. The first disadvantage is that the subsequent stitching operation is an additional cost in production. Another disadvantage is that with this treatment of the seam of the stripped material, the air bubbles remaining in the material itself can open, which can compromise the tightness of the joint of the lid and the housing. Also, the leakage of -leakage -electrolyte is due to the porosity of the seam. This makes it difficult to automatically recharge the electrolyte, ie. automatic control of the electrolyte level based on the drop or increase in the battery pressure during the operation itself.
GPIS FEŠENJA TEHNIČKOG PROBLEMAGPIS TECHNICAL PROBLEM SOLUTIONS
Predmet ovog pronalaska je kučište industrijske akumulatorske baterije, način j eno od termoplastične mase, ko j e uz nepremenjene gabaritne dimenzije ima povečanu zapreninu elektrolita.The object of the present invention is the housing of an industrial rechargeable battery, made of thermoplastic mass, which with unchanged overall dimensions has an increased electrolyte barrier.
Značajna osobina pronalaska je to što je onemogučeno deformisanje tankih zidova kučišta, ko j e nas ta j e usled povečanog hidrostatičkog pritiska elektrolita, naročite kod akumulatorskih baterija velikih dimenzija.An important feature of the invention is that it is impossible to deform the thin walls of the casing, which is even more severe due to the increased hydrostatic pressure of the electrolyte, especially for large-size batteries.
Pronalaskcm je ostvaren još jedan cilj, a to je da se odlivak kučišta zahvaljujuči svan posebnem obliku, nakon izlivanja može seči na različite standardne dimenzije, tako da se od jednog odlivenog poluproizvoda mogu proizvesti baterije različitog kapaciteta.Another objective has been achieved, namely that the casting of the housing, thanks to each special shape, can be cut to different standard dimensions after the casting, so that batteries of different capacities can be produced from one casted semi-finished product.

spoj izmed ju poklopca i tela kučišta garantu je sigurno zap ti vanje, i da je izveden unutar dozvoljenih ukupnih spoljnih dimenzija kučišta.the connection between the lid and the body of the housing is guaranteed to the guarantor, and is made within the permissible overall outer dimensions of the housing.
U opisu koji sledi pronalazak je de tal j no opisan na jednem primeru izvodjenja i sa pozivom na priloženi načrt, na kcme:In the description that follows, the invention is de tally described in one embodiment and with reference to the attached plan, to the following:

Na slici 1 prikazan je spol j ni izgled kučišta akianulatorske baterije oblika paralelcpipeda, odlivenog od tenmoplastične mase (obično od rropilena). rcstupkan duvanja u kalupu. Kučište se sestoji od tela 1 i poklopca 11, koji su spe jeni zavarivanjem na način koji če kasni j e biti opisan. Vertikalni zidovi tela 1 kučišta izvedeni su sa horizontalnim orebrenjima po celem obirnu, tako da u preseku ima ju tzv. izlonljeni profil, delimično prikazan na slici 5. Cvaj profil se na spoljnoj površini vertikalnih zidova kučišta manifestuje u obliku trakastih udubljenja, označenih sa 2,3,4,5,6,7 i 14. Debljina S zidova je konstantna, tj. vertikalni zidovi tela 1 kučišta ima ju istu debljinu S i na mestima pemenutih udubljenja, ko ja su utisnuta na dubinu od 1-2 nm u odnosu na spoljnu konturu. Ovakvim profilisanjem vertikalnih zidova postiže ee krutost ko ja je dovoljna da i anonoguči deformaciju kučišta us led hidrostatičkog pritiska elektrolita. ΪFigure 1 shows the gender and appearance of a parallel-piped cast-iron battery case made of tenmoplastic material (usually of rropylene). a blow mold in the mold. The housing consists of a body 1 and a cover 11, which are welded together in a later manner. The vertical walls of the body of the 1 casing are made with horizontal ribs all over, so that in the cross section there is a so-called. an outlined profile, partly shown in Figure 5. The outer profile on the outer surface of the vertical walls of the housing is manifested in the form of strip recesses, denoted by 2,3,4,5,6,7 and 14. The thickness S of the walls is constant, ie. the vertical walls of the body 1 of the case have the same thickness S and at the points of the recesses, which are imprinted at a depth of 1-2 nm relative to the outer contour. Such profiling of the vertical walls achieves a rigidity which is sufficient to prevent the deformation of the housing due to the hydrostatic pressure of the electrolyte. Ϊ
Naznačena udubljenja su osim toga, razmeštena na različitim višinama koje odgovaraju standardizovanim višinama gotovih kučišta, tako da je, ukoliko je ; to potrebno, moguče prešecanjem tela odlivka duž odgovarajučeg horizontalnog udubljenja dobiti kučište želj ene višine, a koje odgovara standar dizovanim dimenzija' ima. Pcmenuta udubljenja takodje služe i kao vodjioe prilikam postavljanja i smeš- taja akur.ulatora u odgovarajuče okvire (ramove) u ko j ima su fiksirani prilikan eksploatacije.The indicated recesses are furthermore arranged at different heights corresponding to the standard heights of the finished housings, so that, if ; this is necessary, possibly by crossing the body of the casting along the corresponding horizontal recess to obtain a housing of the desired height, which corresponds to the standard designed dimensions'. The recessed recesses also serve as a guide when installing and placing the accu- lator in the appropriate frames (frames) in which it has a fixed attachment.
Kao što se vidi na slikama 2,3 i 5, gornji kraj odlivka kučišta je posebno stepenasto oblikovan. Na slici 3 su uočljiva dva stepenika, označena sa 8 i S). Nakon odlivanja, sečenjem duž ravni A-A, uklanja se stepenik 8, tako da se do4.As seen in Figures 2,3 and 5, the upper end of the housing of the housing is particularly stepped. In Fig. 3 two steps, marked by 8 and S) are noticeable. After casting, by cutting along plane A-A, step 8 is removed so that up to 4.
bi ja čeona gornja ivica vertikalnih zidova kučišta, koja je uvečane površine. Širina ove ivice je jednaka zbiru debljine S zida i ddbine stepenika 8. Ovako dobljena gornja ivica zida kučišta predstavlja površinu, označenu sa 10, ra ko ju naleze poklopac 11 (slika 2). Površina 10 je ujedno površina na kojoj je zavaren poklopac 11. Uočljivo je da je ovakvim oblikovanjem gomjeg dela kučišta ostvarena veča površina zavarivanja, koja obezbedjuje spoj večeg stepena sigurnosti izmed ju tela 1 kučišta i poklopca 11. Ovo je posebno potrebpo za akunrulatore ve.čih dimenzija, čija je višina iznad 500 nrn.the upper edge of the vertical walls of the housing, which is enlarged surface, is at the front. The width of this edge is equal to the sum of the thickness S of the wall and the thickness of the step 8. Thus, the upper edge of the housing wall thus obtained represents the surface marked with 10, which is inserted by the cover 11 (Figure 2). Surface 10 is at the same time the surface on which the cover 11 is welded. It is noticeable that this design of the bulky part of the housing has created a larger welding surface, which provides a connection of a higher degree of safety between the body 1 of the housing and the cover 11. This is especially necessary for larger acculators. of a dimension exceeding 500 nrn in height.
Takodje je sa slike 2 uočljivo da če ee šav od-zavarivanja poklopca 11 i tela 1 kučišta formirati u zonama 12 i 13, duž cele površine 10. Zone 12 i 13 se nalaze unutar spoljnih gabarita kučišta koji ostaju nepranenjeni, i zbog toga ni j e potrebna naknadna obrača šavova.It is also apparent from Figure 2 that the seam of the welding of the lid 11 and the body 1 of the housing will form in zones 12 and 13, along the entire surface 10. The zones 12 and 13 are located within the outer dimensions of the housing which remain intact, and therefore subsequent seam reversal required.
Dubina stepenika 9 se bira prena debljini zida poklopca 11,tako da presavijeni krajevi poklopca 11 ne renete standardne gabarite kučišta, več se mogu smestiti u prostoru koji je ograničen spoljncm knnfnrm kučišta 1 dubincm stepenika 9.The depth of the step 9 is selected over the thickness of the wall of the lid 11, so that the folded ends of the lid 11 do not retract the standard dimensions of the housing, but can be housed in a space limited by the outer knnfnrm of the housing 1 of the depth of the steps 9.
Na slici 5, koja predstavlja delimični poprečni presek gomjeg dela tela 1 kučišta, uočava se udubljenje 14 načlnjeno da bi se ostvarilo ojačanje kod završnog dela kučišta. Ovim se ojačanjem izbegava deformacija kučišta do koje može doči u gornjem delu kučišta usled napora koji se razvijaju u procesu livenja postupkan čuvanja plastične mase, a koji teše da se oslobode nakon sečenja duž ravni &-A. Ova deformacija kučišta je šematski prikazana na slici 6, dok je na slici 7 prikazana deformacija kučišta koja nas ta j e pod pri tiskan elektrolita. Ona je inačf karakteristična za kučišta bez plitkih udubljenja horizontalno rasporedjenih po obimu, prikazanih na slici 1.In Fig. 5, which is a partial cross-section of the bulky part of the body 1 of the housing, a recess 14 is shown to provide reinforcement at the end of the housing. This reinforcement avoids the deformation of the housing which may occur in the upper part of the housing due to the efforts of the molding process, which preserves release after cutting along the & -A plane. This deformation of the housing is shown schematically in Figure 6, while Figure 7 shows the deformation of the housing which places us under the printed electrolyte. It is a characteristic of enclosures without shallow recesses horizontally arranged in circumference, shown in Figure 1.
Na slici 4 prikazan je spoj tela 1 kučišta i poklonca 11 koji obezbedjuje dovolj čin stepen sigurnosti kada se primenjuje kod kračih akumulatorskih baterija. Kučište akumulatorske baterije je formirano tako što je odlivak kučišta presečen duž, na primer, udubljenja 2, na odgovarajučdj višini, čime se od jednog istog odlivka dobi ja kučište zahtevane manje standardne višine. U σναη slučaju, pošto nema dvostrukog stepenika, moguče je koristiti samo onu površinu za zavariv «je koju daje debljina zida kučišta, ali koja 'je dovoljna da Obezbedi sin ur nosno spti^mje. Kako se i u σναη slučaju šav od zavarivanja, koji se pri tone obrazuie, r -uklanja, ipak se unekoliko povečava površina dodira izmedju poklopca 11 i tela aačišta.Figure 4 shows the junction of the body 1 of the housing and the holder 11, which provides a sufficient degree of security when applied to shorter battery packs. The battery casing is formed by cutting the casing outlet along, for example, recesses 2, at a suitable height, giving the same casing the required lower standard height. In the σναη case, since there is no double step, it is possible to use only that surface for welding «that is given by the thickness of the casing wall, but which 'is sufficient to Provide sin ur nasal adhesion. As in the case of σναη, the weld seam formed by the r is bent, however, the contact surface between the cover 11 and the body of the hub is somewhat increased.

karakterističnem slučaju, neprofilisano kučište odliveno postopkom brizganja, imalo bi debljinu zidova oko 3,5 mn, a pri istim spoljnim gabaritima. Pošto dubina udubljenja-2-7,1-4 iznosi 1,5-2 mn, ukupna debljina-SE profila zida (minimalna potrebna debljina za kučišta različitih veličina) iznosi 3,5-4 mn. To znači da se rešenjen prema pronalasku, pri istim spoljnim gabaritima kučišta, u zonama udublje nja ostvaruje ista,. ili tek nešto malo manj a zaprenina elektrolita u odnosu na klasično resenje sa neprofilisandm Židovima. Istovremeno se u zonama rebara (na pr. rebra 15,16 na sl. 5) koja su rasporedjena izmed ju udubljenja po celoj višini kučišta,--ostvaruje uočljivo povečanje zapreni np elpktml -ita, cmogučeno smanjenjen ukupne debljine zidova u tim zonama, za oko 1,5 mn. Poredjenjem dvaju kučišta istih standardnih spoljnih dimenzija (196 x 63 x 400), od kojih je jedno izradjeno prsna;pronalasku, a drugo livenjen postupkan brizganja, utvrdjeno je da unutrašnja zaprenina kučišta prema pronalasku iznosi 4 632 ml, dok je zaprenina standardnog brizganog kučišta 4 295 ml, što čini povečanje zaprenine elektrolita od oko 8%—Ovo-couečanje zaprenine elektrolita dovodi do povečanja kapaciteta akumulatorske baterije od oko 4-6%. Povečana zapremina ostvarena je kučišten sa konstantnem debljinan zidova od oko 2 mn, sa 6 udubljenja na vertikalnim zidovima, pri čemu je širina udubljenja iznosila oko 10 mn, a dubina 1,5 mn.in the typical case, an unprofiled housing made by injection molding would have a wall thickness of about 3.5 mn, and at the same external dimensions. As the recess depth-2-7,1-4 is 1.5-2 mn, the total thickness-SE profile of the wall (minimum thickness required for casings of different sizes) is 3.5-4 mn. This means that, according to the invention, at the same outer dimensions of the housing, the same is achieved in the recess zones. or just a little less and electrolyte constipation compared to the classic non-Jewish Jews solution. At the same time, in the zones of the ribs (eg ribs 15.16 in Fig. 5), which are distributed between the recesses along the entire height of the housing, - a noticeable increase in the closed np elpktml -ita is achieved, thus reducing the total wall thickness in these zones, by about 1.5 mn. By comparing two enclosures of the same standard external dimensions (196 x 63 x 400), one of which is made of the breast; 295 ml, which increases the electrolyte constipation by about 8% —This electrolyte constipation increases the battery capacity by about 4-6%. An increased volume was achieved with a constant wall thickness of about 2 mn, with 6 recesses on the vertical walls, with a recess width of about 10 mn and a depth of 1.5 mn.
