Tehnički problemTechnical problem

Tehnički problem je kako konstrukcijski rešiti posudu akumulatora kod koje de se postiči potrebno zaptlvenost bez zavarivanja, kao i da se omogudi otvaranja posude u slučaju potrebe bez sečenja ili lomljenja.The technical problem is how to design the container of the battery in order to achieve the required sealing without welding, and to allow the container to be opened in case of need without cutting or breaking.

Stanje tehnikeThe state of the art

Poznato je da se poklopci električnih akumulatora spajaju sa svojim kuti jama ili posudama na trajan način da bi se obezbedila dobra zaptivenost izmedju poklopca i posude. Zaptivanje je potrebno kako zbog toga da bi se sprečilo curenje elektrolita za vreme rada akumulatora, tako 1 zbog toga što samo hermetička zaptivenost garantuje dobro funkcionisanje nekih avtomatskih sistema dopunjavanja elektrolita.It is known that the covers of electric batteries connect to their corners or vessels in a durable manner to ensure a good seal between the lid and the container. Sealing is needed both to prevent electrolyte leakage while the battery is running, and 1 because only a sealed seal guarantees the proper functioning of some automatic electrolyte refill systems.

Iz toga razloga, svi akumulatori koji se sada nalaze na tržištu zaptivaju se zavarivanjem poklopca sa posudom, bili direktnim topljenjem plastičnog materijala 111 primenom lepka.For this reason, all the batteries now on the market are sealed by welding the lid with the container, by directly melting the plastic material 111 using adhesive.

Zavarivanje koje se izvodi, bilo sistemom vrelih metalnih ploča, bilo ultrazvučnim sistemom, obrazuje jednu liniju vara, koja mora da se obradi odgovarajudim ur ed ja jima.The welding, whether by hot metal plate system or ultrasonic system, forms a single weld line, which has to be treated with the proper devices.

Mada se zavarivanje poklopca za posudu sada primenjuje kod svih akuraulatora, pomenuto zavarivanje prouzrokuje i odredjene nedostatke.Although the welding of the lid for the container is now applicable to all accumulators, the said welding also causes certain disadvantages.

Uajbitniji nedostatk sastoji se u činjenici da zavareni poklopac više nikada ne može da bude skinut, osim ako se poklopac uništi, a unutraSnjost ošteti.The major disadvantage is that the welded lid can never be removed again unless the lid is destroyed and the interior damaged.

Zato, kada se akumulator pokvari, na primer usled kratkog spoja izmedju ploča, ekonomična popravka nije moguda zbog toga Sto je, kako je rečeno, radi pristupa akumulatorskim pločama neophodno njegovo otvaranje lomljenjem poklopca.Therefore, when the battery breaks down, for example due to a short circuit between the panels, economical repair is not possible because, as stated, accessing the battery panels requires opening it by breaking the lid.

Naročito ako se radi o industrijskim akumulatorima, na primer o onima koji se koriste za elektrovuču, uoČljivo je koliko bi prednost bila ako bi se pomenuti akumulator i, koji su obično vrlo skupi, mogli popravljati.Particularly in the case of industrial batteries, such as those used for electric traction, it is obvious how advantageous it would be if these batteries, and which are usually very expensive, could be repaired.

Sa druge strane, nemogude Je odlučiti se za primenu akumulatora kod kojih su poklopci zaptiveni putem gltovanja, kako je bilo radjeno kod starih konstrukcija, pošto je takav postupak vrlo skup, a ea druge strane nedovoljno pouzdan.On the other hand, it is impossible to decide on the use of batteries in which the covers are sealed by gliding, as was the case with old structures, since such a procedure is very expensive and, on the other hand, not reliable enough.

Drugi nedostatak koji potlče od zavarivanja izmedju poklopca i posudetiče se činjenice da su operacija zavarivanja 1 sledeča, skoro neizbežna, oper aci j aobrad j Ivanja vrlo ekupe operacije, koje zahtevajo i specijalnu opremu.Another drawback from the welding between the lid and the fact that the welding operation 1 is the next, almost inevitable, operation in Ivanjica is a very extensive operation, requiring special equipment.

Opis rešenja tehničkog problema sa prlmerima izvodjenja i popisom 1 kratki» opisom slika načrtaDescription of a solution to a technical problem with performance examples and list 1 short »description of the design drawings

S vrh a ovog pronalaska je da prevazidje gore pomenute nedostatke.The top a of the present invention is to overcome the aforementioned disadvantages.

Naročito je cilj da se reši konstrukcija spoja poklopca sa posutem pogodna za spajanje na stabilen način i sa dobri» zaptivanje», a da pri torne nije potrebno, za ovu svrhu, »edjusobno zavarivati poklopac i posudu.In particular, the aim is to solve the construction of the joint of the lid with a sprinkler suitable for joining in a stable manner and with good “sealing”, without the need for the welding of the lid and the vessel for this purpose.

Drugi cilj je da se dodje do rešenja koje bi omogučilo da se poklopac može fiksirati na posudl samo pritiskanje», tako da se on može 1 skinuti, ako je potrebno, da se omoguči pristup za eventualno održavanje baterije.The second objective is to provide a solution that would allow the lid to be fixed to a pressure-only receptacle "so that it can be removed 1 if necessary to allow access for eventual battery maintenance.

Gore pomenuti ciljev! kao i drugi koji če biti bolje objašnjeni kasnije, postižu se konstrukcijo» posude, poklopca, izradjenog od plastične »ase, gde je moguče da se spajanje poklopca sa posudom akumulatora izvrši jednostavnim pritiskom. Konstrukcija je okarakterisana time , što ima dvostruku ivicu po obimu, kod koga bar jedne od pomenutih ivica ima jedno neprekidno ispupčenje koje naleže na vertikalne zidove posude, koja ima po obimu sa spoljašnje strane reljefno udubljenje ili urez u koji ulaze zupci koji se nalaze na kraju bar jedne Ivice poklopca.The aforementioned goals! as well as others, which will be better explained later, the construction of a "container, lid, made of plastic" is achieved, where it is possible to connect the lid to the battery container by a simple push. The structure is characterized in that it has a double edge in circumference, in which at least one of the said edges has a continuous projection adjacent to the vertical walls of the vessel, having a circumferential recess or a notch in the outside of which there are grooves located at the end at least one edge of the lid.

Druge karakteristike i prednosti akumulatorske posude prema pronalasku biče bolje shvačena lz opisa jednog najpogodnijeg oblika izvodjenja, a koji je prikazan na priloženim crtežima, na kojima slike pokazuju:Other features and advantages of the battery container according to the invention will be better understood by the description of one of the most preferred embodiments, which is shown in the accompanying drawings, in which the figures show:

- Slika 1 delimični poprečni presek poklopca,- Figure 1 is a partial cross-section of the lid,

- Slika 2 poprečni presek Ivice posude akumulatora koja prihvata poklopac sa Slike 1,- Fig. 2 is a cross-sectional view of the edge of the battery receptacle receiving the lid of Fig. 1,

- Slik· 3 poprečni presek poklopca i posude koji su spojeni,- Fig. 3 is a cross-sectional view of the lid and vessels that are connected,

- Slika 4 poprečni presek jednog Ismenjenog poklopca sa Slike 1 u spoju sa odgovara judom posudom.- Figure 4 is a cross-sectional view of one Modified lid of Figure 1 in conjunction with a corresponding jug.

- Slika 5 spoljni izgled akumulatorske posude u zatvorenom stanju.- Figure 5 Exterior of the battery container when closed.

Pozivaj uči se na pomenute crteže, na Slici 2 se može videti profil u poprečnom preseku jedne posude 1 akumulatora, koja je Izradjena od plastičnog materijala liven jem pod pritiskom.Reference is made to the aforementioned drawings; in FIG. 2 a cross-sectional view of one battery container 1, which is made of plastic material by injection molding, can be seen.

Kao što je poznato i opisano u prijavi evropskog patenta br. EP-oo82826, postupkom livenja pod pritiskom mogude je dobiti posude sa ravnim urezanim udubljenjima u vidu kanala duž obima, kako se vidi na poprečnom preseku na Slici 2 i u perspektivne» izgledu na Slici 5. Tačnije rečeno, urez 2, koji se nalazi blizu gornje Ivice posude 1, i vertikalna površina 3 unutar posude 1 koja je obrazovano sa druge strane ureza 2, namenjene su, u slučaju koji se opisuje, za fiksiranje poklopca 4, kako če dalje biti opisano.As is known and described in European patent application no. EP-oo82826, pressurized casting process can provide vessels with straight indented grooves in the form of channels along the circumference, as seen in the cross-section of Figure 2 and perspective views of Figure 5. More specifically, notch 2, located near the upper The edges of the vessel 1, and the vertical surface 3 inside the vessel 1 formed on the other side of the notch 2, are intended, in the case described, for fixing the lid 4, as hereinafter described.

O stvari poklopac 4, koji se takodje napogodnlje izradjuje od plastičnog materi jala, ime dve Ivice 516 čiji se vertikalni profili medjusobno razlikuju, ali Imaju 1 zajedničke karakteristike . Obadve Ivice 5, 6, imaju dva naspramna ispupčenja 7 i 9 koja su tako okrenuta da naležu na zid posude 1, pri čemu je ispupčenje 7 na Ivici 5 niže od Ispupčenja 9 na Ivici 6.The cover 4, which is also conveniently made of plastic material, is the name of two Ivice 516s whose vertical profiles differ from one another, but have 1 common characteristics. Both Edges 5, 6 have two opposite projections 7 and 9 that are so turned that they hang against the wall of the vessel 1, the projection 7 on Ivica 5 being lower than the projection 9 on Ivica 6.

Tačnije rečeno, unutranja ivica 5 poklopca 1 ima ispupčenje 7 sa praktično polukruSnira presekom 1 zubac 8 na donjem kraju . Spoljašnja Ivica 6 takodje ima ispupčenje 9 sa praktično polukružnim presekom 1 zubac lo na donjem kraju.Specifically, the inner edge 5 of the lid 1 has a protrusion 7 with a substantially semicircular cross section of 1 tooth 8 at the lower end. The outer edge 6 also has a projection 9 with a substantially semicircular cross section of 1 tooth at the lower end.

Kada se poklopac 4 zatvori pritiskanjem na ivlcu posude 1, elastičnost materijala ivica 516 omogučuje da se ivice 516 razmaknu, tako da ostave medjuprostor potreban «a uvlečen je Ivice posude 1. Kada se poklopac 4 natakne duS cele Ivice posude 1, po obimu, dobijaju se najmanje tri površine zaptlvanja izmedjuWhen the lid 4 is closed by pushing on the edge of the vessel 1, the elasticity of the material of the edges 516 allows the edges 516 to be spaced apart leaving the space required, and the edges of the vessel 1 are drawn in. When the lid 4 is inserted along the entire edge of the vessel 1, circumferentially, at least three sealing surfaces are sealed between

5.5.

poklopca 4 1 posude 1. Naime, celo ispupčenje 7 unutarnje ivice 5 poklopca 4 koje naleže na unutranju vertikalnu površinu 3 posude 1, celo ispupčenje 9 spoljne ivice 6 poklopca 4 koje naleže na spoljnu površinu 11 posude 1 1 ravna površina <12 poklopca 4 koja se nalazi izmedju ivica 5 i 6 i koja naleže na ivicu 13 posude.namely, the entire projection 7 of the inner edge 5 of the lid 4, which rests on the inside vertical surface 3 of the container 1, the entire protrusion 9 of the outer edge 6 of the lid 4, which rests on the outer surface 11 of the container 1, the flat surface <12 of the lid 4, is located between edges 5 and 6 and which is adjacent to the edge 13 of the vessel.

Pošto je rastojanje izmedju ispupčenje 7 i ispupčenje 9 na Ivicama 5, 6 poklopca 4, kada je poklopac 4 odvojen od posude 1, manje nego što je rastojanje izmedju dveju površina 3 i 11 posude 1, ehvatljivo je da de, kada se poklopac 4 stavi na posudu 1 ispupčenje 7 i 9 pritiskati na površine 3 i 11 posude 1, Čime de obezbediti zaptivenost.Since the distance between the projection 7 and the projection 9 on the edges 5, 6 of the lid 4, when the lid 4 is separated from the vessel 1, is less than the distance between the two surfaces 3 and 11 of the vessel 1, it is acceptable that when the lid 4 is inserted press the projections 7 and 9 on the container 1 to the surfaces 3 and 11 of the container 1, which will secure the seal.

Eksperimentima je utvrdjeno da se dobro zaptivanje Izmedju poklopca 4 i posude 1 postiže kada je negativna razlika izmedju rastojanja ispupčenje 7 i 9 sa jedne strane i izmedju površina 3 i 11 sa druge strane oko 1,5 mm. Zupci 8 1 lo poklopca 4, kako se može videti na preseku na Slici 3, ostaju slobodni ali su respektivno u zahvatu sa urezima 15 i 2 posude 1. Tako, tokom staranja akumulatora, kada polovi teže da se produže 1 da stvore potlsak na gore prema pokiopcu 4, a što se delimično apeorbuje deforroacijom powršine poklopca 4, zupci 8 i lo sprečavaju odvajanje poklopca 4 od posude 1.Experiments have shown that good sealing between cover 4 and container 1 is achieved when the negative difference between the distance of the projections 7 and 9 on one side and between the surfaces 3 and 11 on the other side is about 1.5 mm. The tabs 8 1 and 1 of the cover 4, as can be seen in the cross section of Fig. 3, remain free but are engaging respectively with the notches 15 and 2 of the receptacle 1. Thus, during the aging of the battery, when the poles tend to extend 1 to create an upward impulse according to the lid 4, which is partially apeorbated by the deforroation of the dust of the lid 4, the teeth 8 and lo prevent the separation of the lid 4 from the vessel 1.

Kada, sa druge strane, treba ponovo otvoriti akumulator, na primer da bi se izvršila popravka kratkospojenih ploča, to se može izvršiti delovanjem na elastičnu deformaciju spoljašnjeg zida ivice 6. O stvari, zubac 8 može da predje preko ruba 16, pošto je on dovoljno zaobljen.When, on the other hand, the battery needs to be reopened, for example, in order to repair short circuits, this can be done by acting on the elastic deformation of the outer wall of the edge 6. In fact, the tooth 8 can extend over the edge 16, since it is sufficient. rounded.

Jedna varijanta koja ee odnosi na poklopac prikazana je na Slici 4, gde poklopac 2o ima dve Ivice 21 i 22 po svome obimu, ali u ovome slučaju postoji samo jedno ispupčenje 23, koje se nalazi na zidu spoljašnje ivice 21 i koje naleže na urezanu ivicu 24 posude 25.One variant that relates to the cover is shown in Fig. 4, where cover 2o has two edges 21 and 22 in circumference, but in this case there is only one projection 23, which is located on the wall of the outer edge 21 and which is adjacent to the incised edge 24 vessels 25.

6.6.

Pored toga, na poklopcu 2o postoji samo jedan zubac 26 koji se suprotstavlja popuštanju napetosti poklopca 2o.In addition, there is only one tooth 26 on the cover 2o that opposes the tension relief of the cover 2o.

ϋ prikazanoj varijanti posuda 25 ima pojednostavljen oblik sa jednom ivicom 24 po celom obimu. Ova je ivica 24 tako dimenzionlsana , da profil spoljašnje ivice 21 poklopca 2o ne viri izvan ravni vertikalnog zida posude 25.In the embodiment shown, container 25 has a simplified shape with one edge 24 over its entire circumference. This edge 24 is so dimensioned that the profile of the outer edge 21 of the lid 2o does not extend beyond the plane of the vertical wall of the vessel 25.

Zaptivenost izmedju poklopca 2o i posude 25, u ovome slučaju je obezbedjena lspupčenjem 23 po obimu, ravnom ivicom 27 posude 25 koja je u dodiru sa poklopcem 2o i dodirom izmedju vertikalnih površina unutranje ivice* 22 i ivice 24 posude 25.The seal between the lid 2o and the vessel 25, in this case is provided by a projection 23 in circumference, a straight edge 27 of the vessel 25 which is in contact with the lid 2o and the contact between the vertical surfaces of the inner edge * 22 and the edge 24 of the vessel 25.

Važno je istači da kod oba data primera spoljašnja ivica poklopca 4, 2o nikada ne viri izvan površine vertikalnih zidova posuda 1, 25. Tako je moguče formirati akumulatorsko baterlju bez gubljenja ni najmanjeg medjuprostora izmedju suaednih akumulatora.It is important to point out that, in both cases, the outer edge of the cover 4, 2o never extends beyond the surface of the vertical walls of the receptacles 1, 25. It is thus possible to form a battery pack without losing even the slightest gap between adjacent batteries.

Iz opisa primera načina izvodjenja koji su dati gore, može se videti da se zaptivanje izmedju posude postiže bez potrebe za zavarivanjem. Pored toga, poklopac 4 se može skinuti u slučaju kvara akumulatora koristeči njegovu elastičnost i bez lemljenja bilo poklopca 4, 2o bilo posude 1, 25.From the description of the exemplary embodiments given above, it can be seen that sealing between the vessels is achieved without the need for welding. In addition, the cover 4 can be removed in the event of a battery failure using its elasticity and without soldering either the cover 4, 2o or the container 1, 25.

Postoji mogučnost za unošenje izmena, bilo konstrukcionih bilo u oblika, u odnosu na ovaj pronalazak. Na primer, oblik ili položaj ispupčenja 719 dvaju ivica 5, 6, kao i oblik i položaj zubaca 8 i lo, ili oblik udubljenja na posudi 1 u koje ulazi poklopac 4 mogu se menjati. Sve to se može izvesti bez izlaženja izvan obimaovog pronalaska, kako je opisano u sledečim zahtevima.There is an opportunity to make changes, either structural or in shape, with respect to the present invention. For example, the shape or position of the projection 719 of the two edges 5, 6, as well as the shape and position of the teeth 8 and lo, or the shape of the recesses on the receptacle 1 into which the lid 4 enters may be changed. All of this can be done without going beyond the scope of the invention, as described in the following claims.
