V zaključni nalogi smo se posvetili problemu neustreznega tesnjenja na nosilcu baterij v električnem avtomobilu. Pregledali smo razpoložljive tehnologije, ki bi ustrezale zahtevam. Opredelili smo se predvsem na tehnologije, ki so v čim večji meri izvedljive na obstoječi konstrukciji in je eden od njihovih namenov uporabe zagotovitev tesnjenja. S pregledom smo dobili vpogled na mehanizme delovanja različnih tehnologij, kar je pomagalo pri izbiri ustreznih rešitev. Iz glavnih zahtev in razpoložljivih rešitev smo naredili morfološko matriko ter nato snovali koncepte. Koncepte smo vrednotili glede na podane zahteve. Izbrali smo najustreznejši koncept, ga detajlno opredelili ter podali razloge za njegovo izbiro. Opravili smo tudi lupilni test, s katerim smo določili najustreznejšo tesnilno maso za uporabo v našem konceptu. Predlagali smo končno rešitev z ozirom na trenutno stanje v proizvodnji. Tako smo izbrali koncept z nanašanjem silikona s tehnologijo pnevmatičnega brizganja. Na izbiro je najbolj vplivala zmanjšana poraba materiala in to, da je potrebnih le nekaj sprememb na konstrukciji. Proces izdelave je prav tako hitrejši, kar še dodatno zmanjša proizvodne stroške. In the bachelor's thesis, we focused on the problem of unsuitable sealing of the battery carrier in electric car. The available technologies that would meet the requirements were reviewed. We focused mainly on the technologies, which are as feasible as possible on the existing structure and one of their purposes is to ensure sealing. The review provided insight into the mechanism of operation of various technologies, which helped in the selection of the appropriate solutions. From the main requirements and available solutions, a morphological matrix was made and then the concepts were devised. The concepts were evaluated based on the given requirements. The most appropriate concept was selected, defined in detail and the reasons for our decision were introduced. A peel test was also performed with which we determined the most suitable sealant to use in our concept. The final solution was proposed, regarding the current state of the production. Thus, the concept of applying silicone with pneumatic spraying technology was chosen. The choice was most affected by the reduced material mass and the fact that only a few changes in the construction are needed. The manufacturing process is also faster, which further reduces production costs. |
