Description

Oblast tehnike u koju spada izum The technical field to which the invention belongs

Izum spada u područje elektrokemije, bliže u oblast konstrukcije akumulatora, a specifično u oblast konstrukcija poklopaca akumulatorskih baterija pogodnih za prenošenje i skladištenje. The invention belongs to the field of electrochemistry, closer to the field of battery construction, and specifically to the field of construction of battery covers suitable for transport and storage.

Tehnički problem Technical problem

Tehnički problem je kako konstrukcijski riješiti izradu akumulatorskih baterija koje su pogodne za stavljanje jedne povrh druge radi skladištenja, kao i za prenošenje, a ne zahtijevaju dopunske operacije prilikom izrade. The technical problem is how to structurally solve the production of accumulator batteries that are suitable for placing one on top of the other for storage, as well as for transportation, and do not require additional operations during production.

Stanje tehnike State of the art

Poznata je činjenica da akumulatorske baterije, naročito one koje se upotrebljavaju u automobilima, imaju električne karakteristike i sve dimenzije standardizirane međunarodnim propisima, štoviše bi trebalo, preporučljivo, iako ne i neophodno da ispunjavaju i neke druge zahtjeve, kao na primjer mogućnost redanja jedne povrh drugih radi skladištenja. It is a well-known fact that accumulator batteries, especially those used in cars, have electrical characteristics and all dimensions standardized by international regulations, moreover, it should be recommended, although not necessary, that they also meet some other requirements, such as the possibility of stacking one on top of the other for storage.

Druga karakteristika koja je poželjna, je da sve ćelije koje čine bateriju imaju iste volumene elektrolita. To je očevidno stoga, što isti volumen elektrolita u svakoj ćeliji koja čini bateriju, osigurava isto trajanje baterije za svaku ćeliju. Another characteristic that is desirable is that all the cells that make up the battery have the same volume of electrolyte. This is obvious because the same volume of electrolyte in each cell that makes up the battery ensures the same battery life for each cell.

Dalji je zahtjev pri konstrukciji baterija, a naročito automobilskih ili u svakom slučaju starterskih baterija, da budu pogodne za transport i lake za rukovanje. Zbog toga ih mnogi proizvođači opskrbljuju drškom za prenošenje. A further requirement in the construction of batteries, especially automotive or in any case starter batteries, is that they should be suitable for transport and easy to handle. This is why many manufacturers supply them with a carrying handle.

Kod nekih konstrukcija drška je dio baterije koji je zakvačen na kutiju baterije pomoću pogodnih ispusta. Druge konstrukcije imaju traku koja prolazi kroz podesne rupe u obodu poklopca. Neke druge konstrukcije imaju čvrstu dršku izlivenu u stalnom položaju na kutiji baterije. Očigledno, bez obzira na geometriju poklopca, u slučajevima kada je drška kruto spojena s poklopcem, baterije se ne mogu stavljati jedna povrh druge. In some designs, the handle is a part of the battery that is attached to the battery box by means of convenient outlets. Other designs have a strap that passes through adjustable holes in the rim of the lid. Some other designs have a solid handle cast in a permanent position on the battery box. Obviously, regardless of the geometry of the cover, in cases where the handle is rigidly connected to the cover, the batteries cannot be stacked on top of each other.

U drugim slučajevima, kad drška predstavlja element dodat bateriji, redanje jedne baterije povrh druge može biti moguće, zavisno od geometrije poklopca, no dopunski troškovi očevidni su uslijed dodatnog dijela i njegove montaže na bateriju. In other cases, when the handle is an element added to the battery, stacking one battery on top of the other may be possible, depending on the geometry of the cover, but additional costs are obvious due to the additional part and its mounting on the battery.

Konačno, kod nekih konstrukcija poklopac ima bočna udubljenja koja olakšavaju prenošenje, ali zahtijevaju da se korisnik uvijek služi s obje ruke. Finally, some designs have side recesses on the lid that make it easier to carry, but require the user to use both hands at all times.

Budući da je poznata činjenica da sve automobilske baterije moraju imati u poklopcu bar jedan otvor za ponovno punjenje elektrolitom zajedno s kapom, za svaku ćeliju baterije, i dva pola koji čine završne priključke baterije, jasno je da karakteristike koje omogućuju slaganje baterija jedne povrh druge, kao i postojanje jednakih količina elektrolita u svakoj ćeliji zavise potpuno od geometrije poklopca. Since it is a well-known fact that all car batteries must have in the cover at least one opening for refilling the electrolyte together with the cap, for each cell of the battery, and two poles that make up the final connections of the battery, it is clear that the characteristics that allow the batteries to be stacked one on top of the other, as well as the existence of equal amounts of electrolyte in each cell depend entirely on the geometry of the cover.

Druge poznate konstrukcije predviđaju mogućnost da baterije budu naslagane jedna povrh druge, ali ta konstrukcija žrtvuje jednakost volumena elektrolita u svim ćelijama. Kod drugih konstrukcija svaka ćelija ima isti volumen elektrolita, ali mogućnost slaganja baterija jedne povrh druge nije osigurano zbog postojanja niza kapica za punjenje elektrolitom. Svrha ovog izuma je da se prebrode opisane nepogodnosti. Other known constructions provide for the possibility of batteries being stacked one on top of the other, but this construction sacrifices the equality of electrolyte volume in all cells. In other constructions, each cell has the same volume of electrolyte, but the possibility of stacking batteries one on top of the other is not ensured due to the existence of a series of caps for filling with electrolyte. The purpose of this invention is to overcome the disadvantages described.

Prvi cilj je ostvarenje poklopca baterije koji ima jednu ili više drški inkorporiranih u samom poklopcu. The first goal is to realize a battery cover that has one or more handles incorporated into the cover itself.

Drugi predloženi cilj je da se poklopca dopuni jednom ili s više drški takvog oblika da se omogući slaganje jedne baterije povrh druge, a koje imaju poklopac prema izumu. Another proposed objective is to complement the cover with one or more handles of such a shape as to enable the stacking of one battery on top of another, which have a cover according to the invention.

Još jedan cilj izuma je da se poklopac za slaganje jedne baterije povrh druge dopuni drškom, formirajući bateriju s jednakim volumenom elektrolita u svakoj ćeliji. Another object of the invention is to supplement the lid for stacking one battery on top of another with a handle, forming a battery with an equal volume of electrolyte in each cell.

Svi ovi ciljevi postignuti su pomoću poklopca baterije načinjenog od plastičnog materijala koji je u skladu s patentnim zahtjevom, karakteriziran s time što ima dva paralelopipedna elementa koji čine dio poklopca i koji imaju istu visinu, a smješteni su na dužim stranama baterije, pri čemu jedan od ovih elemenata ima rupe za ponovno punjenje elemenata baterije elektrolitom i pri čemu su ovi paralelopipedni elementi spojeni međusobno najmanje jednim poprečnim komadom koji služi kao drška. All these objectives are achieved by means of a battery cover made of a plastic material which is in accordance with the patent claim, characterized by having two parallelopiped elements forming part of the cover and having the same height and located on the longer sides of the battery, one of of these elements has holes for refilling the battery elements with electrolyte and wherein these parallelepiped elements are connected to each other by at least one transverse piece that serves as a handle.

Opis rješenja tehničkog problema s primjerima izvođenja i popisom te kratkim opisom slika nacrta Description of the solution to the technical problem with implementation examples and a list and brief description of the drawings

Izum se odnosi na poklopac akumulatorskih baterija sa jednim ili više inkorporiranih drški. The invention relates to a battery cover with one or more incorporated handles.

U skladu s izumom oblik poklopca osigurava prije svega, isti volumen elektrolita za svaku ćeliju, budući da su dva paralelopipedna elementa koje ima poklopac raspoređena paralelno i simetrično. In accordance with the invention, the shape of the cover ensures, first of all, the same volume of electrolyte for each cell, since the two parallelopiped elements of the cover are arranged parallel and symmetrically.

Dalje je redanje baterija jedna povr druge također osigurano i time što su oba paralelopipedna elementa iste visine, te čine ravnu noseću površinu volumena baterije koje se slažu jedna na drugu. Konačno, jedan ili više spojnih elemenata koji postoje između dva paralelopipedna elementa formiraju jednu ili više drški pogodnih za dizanje i prenošenje baterije. Furthermore, the stacking of batteries one on top of the other is also ensured by the fact that both parallelepiped elements are of the same height, and they form a flat supporting surface of the battery volumes that are stacked on top of each other. Finally, one or more connecting elements existing between two parallelepiped elements form one or more handles suitable for lifting and carrying the battery.

Jedna od prednosti koju pruža ovaj izum je što je drška na poklopcu dio samog poklopca i ne uvećava cjelokupne dimenzije baterije. One of the advantages provided by this invention is that the handle on the cover is part of the cover itself and does not increase the overall dimensions of the battery.

Dalja prednost sastoji se u tome što se drška dobiva direktno prilikom procesa izrade poklopca bez dopunskih troškova za njenu montažu. Štaviše, sama po sebi ne predstavlja dodatni element baterije. A further advantage consists in the fact that the handle is obtained directly during the process of making the cover without additional costs for its assembly. Moreover, it does not represent an additional battery element by itself.

Druge prednosti i karakteristike izuma bolje će se razumijeti iz opisa dvaju preporučenih formi izvođenja, datog na temelju crteža, a koji ne predstavljaju ograničenje. Na priloženim crtežima su: Other advantages and characteristics of the invention will be better understood from the description of the two recommended embodiments, given on the basis of the drawings, which do not represent a limitation. The attached drawings show:

- sl. 1. akumulatorska baterija sa poklopcem prema izumu, - Fig. 1. Accumulator battery with cover according to the invention,

- sl. 2. druga baterija sa varijacijom poklopca prema izuma, - Fig. 2. second battery with variation of the cover according to the invention,

- sl. 3. izgled poklopca sa sl. 1. odozgo, - fig. 3. the appearance of the cover from fig. 1. from above,

- sl. 4. izgled poklopca sa sl. 2. odozgo. - fig. 4. cover appearance from fig. 2. from above.

Na spomenutim crtežima može se vidjeti baterija, na sl. 1, označena kao cjelina sa 10, koja predstavlja kontejner 1 zatvoren odozgo poklopcem 2. Ovaj poklopac, što se vidi na sl. 3. izliven je od plastičnog materijala i ima dva paralelopipedna elementa 3 i 4. Paralelopiped 3 ima neprekidni rub 5 koji ograničava udubljenu ravnu površinu 6 u kojoj se nalaze otvori 7 koji omogućuje punjenje dopunjavanje elektrolita za svaku ćeliju, odnosno element, koji čini bateriju. S druge strane, paralelopiped 4 predstavlja ravnu površinu u kojoj se nalazi rupa 11 koja služi za provjeru električnog punjenja baterije. In the mentioned drawings, you can see the battery, in Fig. 1, marked as a unit with 10, which represents a container 1 closed from above by a cover 2. This cover, which can be seen in Fig. 3, is molded from plastic material and has two parallelopiped elements 3 and 4. The parallelepiped 3 has a continuous edge 5 that delimits a concave flat surface 6 in which there are openings 7 that enable filling and replenishment of the electrolyte for each cell, or element, that makes up the battery. On the other hand, the parallelepiped 4 represents a flat surface in which there is a hole 11 that serves to check the electric charge of the battery.

Na sredini poklopca 2 nalaze se također polovi 12 i 13 baterije. Paralelopipedni elementi 3 i 4 spojeni su jedan s drugim u slučaju poklopca sa sl. 1 poprečnim komadom 14 čija je debljina manja od visine paralelopipeda 4 i ruba 5 paralelopipeda 3, tako da korisnik može lako uvući ruku u otvor između donje strane poprečnog komada 14 i površine 15 poklopca ispod poprečnog komada 14. Poprečni komad 14, koji čini dršku nalazi se u položaju težišta i direktno je izliven za vrijeme postupka lijevanja poklopca 2. In the middle of cover 2 there are also poles 12 and 13 of the battery. The parallelepiped elements 3 and 4 are connected to each other in the case of the cover with Fig. 1 by a transverse piece 14 whose thickness is smaller than the height of the parallelepiped 4 and the edge 5 of the parallelepiped 3, so that the user can easily insert his hand into the opening between the lower side of the transverse piece 14 and surface 15 of the cover under the transverse piece 14. The transverse piece 14, which forms the handle, is located in the position of the center of gravity and was directly cast during the casting process of the cover 2.

Može se zapaziti da korisnik, kako uhvati bateriju 10, za ručicu 14 jednom rukom, može je držati u uravnoteženom položaju, što predstavlja očiglednu prednost i pri držanju i prenošenju baterije. It can be observed that the user, as he grasps the battery 10, by the handle 14 with one hand, can hold it in a balanced position, which is an obvious advantage when holding and transferring the battery.

Slika 2. prikazuje varijaciju izrade poklopca prema izumu gdje postoje tri poprečna komada umjesto jednog. Točnije, baterija 20 ima poklopac 21 sa dva paralelopipedna elementa 22 i 23, koji su spojeni pomoću tri drške 24, 25 i 26 respektivno. Figure 2 shows a variation of the lid construction according to the invention where there are three transverse pieces instead of one. Specifically, the battery 20 has a cover 21 with two parallelepiped elements 22 and 23, which are connected by means of three handles 24, 25 and 26 respectively.

Postojanje triju drški na poklopcu 21, mjesto jedne, omogućuje biranje pri dizanju baterije, jednom rukom, hvatajući srednju dršku 25, ili dvjema rukama hvatajući bočne drške 24 i 26. The existence of three handles on the cover 21, instead of one, allows selection when lifting the battery, with one hand, grasping the middle handle 25, or with two hands, grasping the side handles 24 and 26.

Kod ovog modela također je osigurana komplanarnost dvaju paralelopipednih elemenata 23 i 24. In this model, the coplanarity of the two parallelepiped elements 23 and 24 is also ensured.

Štoviše volumentrička simetrija ovih elemenata osigurava jednake volumene elektrolita za svaku ćeliju baterije. Moreover, the volumetric symmetry of these elements ensures equal volumes of electrolyte for each cell of the battery.

Drugi primjeri konstrukcije mogu predvidjeti izradu poklopca sa dvije drške umjesto tri, odnosno jedne, što se u svakom slučaju može postići direktnim lijevanjem na poklopcu i bit će uključene u cjelokupne dimenzije samog poklopca. Other examples of construction may provide for the creation of a cover with two handles instead of three or one, which in any case can be achieved by direct casting on the cover and will be included in the overall dimensions of the cover itself.
