Description

Uprawniony z patentu: VARTA Aktiengesellschaft, Frankfurt n/Menem (Republika Federalna Niemiec) Skrzynka blokowa dla wieloogniwowych akumulatorów 10 Przedmiotem wynalazku jest skrzynka blokowa dla wieloogniwowych akumulatorów skladajaca sie z dwóch elementów pokrywy i obudowy, wy¬ posazona w scianki rozdzielajace poszczególne og¬ niwa, których krawedzie znajduja sie w plaszczyz¬ nie obrzeza zewnetrznego.Znane tego rodzaju skrzynki blokowe sa z reguly wytwarzane z polipropylenu, polietylenu, polisty¬ renu lub z tworzywa sztucznego zbrojonego wlók¬ nem. Po wlozeniu pakietów plyt akumulatorowych wymagane jest szczelne polaczenie pokrywy z obu¬ dowa, przy równoczesnym zapewnieniu calkowitej wzajemnej szczelnosci poszczególnych ogniw skrzynkiblokowej. 15 Znane sa rózne sposoby laczenia elementów wy¬ konanych z tworzyw termoplastycznych, a w szcze¬ gólnosci laczenia pokryw i obudów blokowych skrzynek akumulatorów. Krawedzie laczonych czesci, z reguly posiadaja wzajemnie zazebiajace 20 sie rowki, które na przyklad przed zlozeniem sa posmarowane plynna masa klejaca, a po zlozeniu sa docisniete az do stezenia masy. Istotna wada tego sposobu jest dlugi czas potrzebny do ustale¬ nia polaczenia tworzyw sztucznych, gdyz ulotnie- 25 nie rozcienczalnika wzglednie polimeryzacja masy laczacej w normalnej temperaturze pokojowej przebiega stosunkowo powoli. Ponadto klejenie niektórych tworzyw, na przyklad polipropylenu, jest wyjatkowo trudne do przeprowadzenia ze 30 wzgledu ma to, ze zwykle stosowane kleje wykazu¬ ja niewystarczajaca przyczepnosc do tych tworzyw.Znana jest równiez taka skrzynka blokowa wy¬ konana z tworzywa sztucznego, w której na dolnej powierzchni pokrywy wykonany jest zlobek, obej¬ mujacy górne krawedzie wszystkich scian obudo¬ wy. Przy zalozonej pokrywie, wzdluz wewnetrznej, ograniczajacej powierzchni zlobka pozostaje wolna przestrzen stanowiaca nieprzerywany kanal wtrys¬ kowy utworzony przez laczone ze soba czesci skrzynki. W kanal ten jest bezposrednio wtryski¬ wana plynna masa wiazaca.Znane jest takze zgrzewanie pokryw i obudów skrzynek blokowych dla akumulatorów przy po¬ mocy pradów wielkiej czestotliwosci, przy czym pomiedzy zgrzewane czesci wprowadzano dodatko¬ we materialy pobierajace w strefie zgrzewania, z pola wielkiej czestotliwosci, wiecej energii niz same czesci zgrzewane. Dzieki temu nagrzewanie zostaje (skupione w strefie zgrzewania. Wada tego sposobu jest jednak zlozona i kosztowna aparatura, konieczna do stosowania tego sposobu laczenia po¬ krywy z obudowa.W technice budowy akumulatorów szczególnie korzystnym jest sposób zgrzewania lustrzanego, w którym zgrzewane ze soba czesci obudowy i po¬ krywy sa nagrzewane do temperatury miekniecia, po czym sa stykane ze soba i dociskane. Obydwie zgrzewane ze soba czesci sa nagrzewane na drodze promieniowania i konwekcji przez plyte grzejna 8158381583 umieszczona równolegle i w jednakowym odstepie do zgrzewanych powierzchni, dzieki czemu nagrze¬ wanie tych czesci jest jednakowe.Wspomniany sposób zgrzewania lustrzanego obar¬ czony jest jednak powazna wada. Scianki dzialo¬ we zasobnika polipropylenowego posiadaja grubosc na przyklad 1,5 do 2,5 mm, moga sie latwo wygiac podczas ukladania pakietów plyt. Równiez i pod¬ czas nagrzewainia moga powstawac wygiecia. Pod¬ czas dociskania, scianki dzialowe w pokrywie i w obudowie nie znajduja sie we wszystkich miej¬ scach dokladnie naprzeciwko siebie, co wywoluje szkodliwe w skutkach nieszczelnosci.Mi jest usuniecie wad znanych ialne uksztaltowanie zasobni- "Wyj i pokrywy.F-ffpdMtmfc^^ilTO^l1*^"1 zadanie to zostalo roz ^ _., L\rozdzielajace ogniwa scianki pofcrywie i/lub obudowie, ma swych krawedziach co najmniej w niektórych miejscach maja szersze od scianek dzialowych zebra, które sa wykonane juz podczas wytwarzania pokrywy wzglednie obu¬ dowy. Zebra te wykonuje sie przez zastosowanie w formie przesuwanych rdzeni. Wyjatkowo korzy¬ stnym jest jednak wytwarzanie zeber w postaci ukladów mostków laczacych zwiazanych z pakie¬ tami plyt. Mostki sa osadzone w wybraniach scia¬ nek dzialowych skrzynek blokowych, po czym na drodze wtrysku polaczenia sa oblewane, a wybra¬ nia zalewane tworzywem sztucznym, przy czym w czasie zalewania wybran górne krawedzie scia¬ nek dzialowych uzyskuja zebra. Zebra te moga byc wykonane tylko na czesciach krawedzi scianek rozdzielajacych ogniwa, zaleca sie jednak by roz¬ ciagaly sie one wzdluz calych krawedzi tychze scianek.Przedmiot wynalazku jest przedstawiony w przy¬ kladzie wykonania ma rysunku, na którym przed¬ stawiono perspektywicznie i czesciowo w przekroju skrzynke blokowa, skladajaca sie z pokrywy 2 i obudowy 1. Scianki rozdzialajace ogniwa znaj¬ dujace sie w obudowie oznaczono 3, a scianki roz¬ dzielajace ogniwa i znajdujace sie w pokrywie oz¬ naczono 4. Scianki rozdzielajace ogniwa zarówno w obudowie jak i w pokrywie posiadaja zebra 5, Przy grubosci scianki dzialowej wynoszacej 1,5 do 2,5 mm, szerokosc zebra wynosi 3 do 5 mm. Zebro ma przekrój w przyblizeniu kwadratowy, a na swej dolnej krawedzi przechodzi stopniowo w scianke rozdzielajaca ogniwa.Jest oczywistym, ze mozna wyposazyc w zebro wedlug wynalazku jedynie pokrywe lub jedynie zasobnik. Szczególnie korzystnym jest wyposazenie w zebra wedlug wynalazku wylacznie zasobnika. PL PL PL PL PL PL PLPatent holder: VARTA Aktiengesellschaft, Frankfurt am Main (Federal Republic of Germany) Block box for multi-cell batteries 10 The subject of the invention is a block box for multi-cell batteries consisting of two elements of a cover and a housing, provided with walls separating the individual cells, the edges of which are flush with the outer periphery. Known block boxes of this type are generally made of polypropylene, polyethylene, polystyrene or fiber-reinforced plastic. After inserting the battery packs, it is required to tightly connect the cover with the casing, while at the same time ensuring complete mutual tightness of the individual cells of the block box. Various methods of joining elements made of thermoplastics are known, and in particular of joining covers and block housings of battery boxes. The edges of the parts to be joined as a rule have overlapping grooves which, for example, are lubricated with a liquid adhesive before assembly, and pressed until the mass is assembled. A significant disadvantage of this method is the long time required to establish the joint of the plastics, since the volatilization of the diluent or the polymerization of the joint compound at normal room temperature proceeds relatively slowly. Moreover, the gluing of certain materials, for example polypropylene, is extremely difficult to carry out because the commonly used adhesives show insufficient adhesion to these materials. on the surface of the cover, a groove is formed which embraces the upper edges of all the walls of the housing. With the cover in place, a free space is left along the inner, delimiting surface of the cavity, constituting an uninterrupted injection channel formed by the interconnecting parts of the box. Liquid binding mass is directly injected into this channel. It is also known to weld the covers and housings of block boxes for batteries by means of high-frequency currents, with additional collecting materials being introduced between the parts to be welded in the welding zone, from a high-frequency field. , more energy than only the welded parts. As a result, the heating is concentrated in the welding zone. The disadvantage of this method, however, is the complex and expensive apparatus necessary for this method of connecting the cover to the housing. and the lids are heated to the softening temperature, then they are pressed together and pressed together. Both parts welded together are heated by radiation and convection by a heating plate 8158381583 placed parallel and with equal distance to the surfaces to be welded, thus heating them However, the above-mentioned method of mirror welding has a serious disadvantage. The dividing walls of the polypropylene container have a thickness of, for example, 1.5 to 2.5 mm, they can easily bend during the stacking of panels. bends may arise During tightening, the partition walls in the lid and in the perimeter the thighs are not exactly opposite to each other in all places, which causes harmful leaks. It is to eliminate the known defects and shape the reservoirs- "Exit and cover. F-ffpdMtmfc ^^ ilTO ^ l1 * ^" The walls separating the cells of the fringes and / or the casing have their edges at least in some places wider than the dividing walls of the zebra, which are already made during the manufacture of the cover or the casing. These zebra are made by using in the form of sliding cores. However, it is extremely advantageous to manufacture the ribs in the form of bridge arrangements associated with the plate packs. The bridges are embedded in the recesses of the partition walls of the block boxes, and then the joints are poured by injection, and the recesses are poured with plastic, while during pouring the selected upper edges of the partition walls are obtained by ribs. These ribs may only be made on the edge parts of the cell separating walls, but it is recommended that they extend along the entire edges of these walls. The subject matter of the invention is shown in an example of a drawing, which is shown in perspective and partially in section. a block box, consisting of a cover 2 and a housing 1. Cell separating walls in the housing are marked 3, and cell separating walls and in the cover are marked 4. Cell separating walls in both the housing and the cover have zebra 5, With a partition wall thickness of 1.5 to 2.5 mm, the width of the zebra is 3 to 5 mm. The zebra has an approximately square cross-section, and on its lower edge it gradually turns into a wall separating the links. It is obvious that according to the invention, it is possible to equip the rib with only a cover or only a container. According to the invention, it is particularly advantageous to provide only a magazine with the zebra. PL PL PL PL PL PL PL PL
