Abstract
Description
Tehnikavaldkond Technical field
Leiutis käsitleb jalgratast, täpsemalt modulaarset elektrijalgratast ning konkreetsemalt modulaarset jalgrattaraami, mis on kohandatav kasutamiseks nn tavalise, ainult inimese lihaste jõul edasi liikuva jalgrattana kui ka nn elektrijalgrattana, milles on edasiliikumiseks ka elektrimootor. Samuti on leiutis suunatud jalgrattale, mis on kohandatud spetsiaalselt jalgrattaringlusele ja renditeenustele mõeldud jalgrataste jaoks, mis võimaldab jalgratast kohandada vastavalt pakutavale teenusele ning mis võimaldab teostada lihtsasti hooldust ja remonti. The invention relates to a bicycle, more specifically a modular electric bicycle, and more specifically a modular bicycle frame, which is adaptable for use as a so-called conventional bicycle, propelled solely by human muscle power, as well as as a so-called electric bicycle, which also has an electric motor for propulsion. The invention is also directed to a bicycle adapted specifically for bicycles intended for bicycle circulation and rental services, which allows the bicycle to be adapted according to the service provided and which allows for easy maintenance and repair.
Tehnika tase State of the art
Rahvusvahelisest patenditaotlusest WO2023180928A1 (avaldatud 28.09.2023) on tuntud lahendus, kus tavapärasele jalgrattale on võimalik paigaldada eraldiseisev jõuülekanne, peale mida on jalgratas kasutatav elektrilise jõuajamiga jalgrattana. Eraldiseisev jõuajam kinnitatakse raamile spetsiaalsete poolkaarjate kinnitusklambritega. Jõuajami veovõllil on hammasratas, mis joondatakse rattaketiga ühele joonele ning pannakse ketiga hambuma. International patent application WO2023180928A1 (published 28.09.2023) describes a solution where a separate drivetrain can be installed on a conventional bicycle, after which the bicycle can be used as a bicycle with an electric drivetrain. The separate drivetrain is attached to the frame with special semi-circular mounting brackets. The drivetrain driveshaft has a gear that is aligned with the wheel chain and meshes with the chain.
Asetuse poolest paikneb jõuajami hammasratas ratta keskjooksu hammasratta kohal ning kett jookseb üle veoajami hammasratta, siis keskjooksu hammasratta ning viimasena tagarattavõllil oleva hammasratta. Veoajami võlli ja hammasrattaga kantakse keskjooksu hammasrattale veojõud, mis aitab kasutajal vähendada väntamiseks vajaminevat jõudu ja viib jalgratast kergemine edasi. The drive sprocket is positioned above the bottom bracket sprocket, and the chain runs over the drive sprocket, then the bottom bracket sprocket, and finally the sprocket on the rear wheel shaft. The drive shaft and sprocket provide traction to the bottom bracket sprocket, which helps the user reduce the amount of force needed to crank the bike and makes it easier to move forward.
Selle lahenduse puuduseks on veoajami elektrimootori ja aku ühes modulaarses komponendis olemine, mis muudab mooduli väga suureks ja piirab selle paigaldamise võimalikke asukohtasid - komponent peab igal juhul asuma keskjooksu peal sõitja jalgade vahel. Elektrimootori või aku vea esinemise korral on vaja kogu komponent välja vahetada - olenemata, kas hooldust või parandamist vajavad mõlemad või ainult üks nimetatud komponentidest. The disadvantage of this solution is that the electric motor and battery of the traction drive are in one modular component, which makes the module very large and limits the possible locations for its installation - the component must in any case be located on the bottom bracket between the rider's legs. In the event of a fault in the electric motor or battery, the entire component must be replaced - regardless of whether both or only one of these components require maintenance or repair.
Tegemist on tavalisele jalgrattale lisatava komponendiga, mis lisab jalgrattale massi. Elektrimootori lisamisega peab mehaaniline keskjooks jääma endiselt jalgrattale, et sellega oleks võimalik sõita. It is a component added to a regular bicycle that adds weight to the bike. With the addition of an electric motor, the mechanical bottom bracket must still remain on the bike in order for it to be ridden.
Leiutise olemus The essence of the invention
Leiutisega lahendatakse jalgrattaringluse ja jalgrataste renditeenusega seotud spetsiifilisi probleeme, mida on kirjeldatud täpsemalt allpool. The invention solves specific problems related to bicycle circulation and bicycle rental services, which are described in more detail below.
Rattaringluse ja renditeenuse turul on kolm enamlevinud süsteemi – laadimisjaamadega, vahetatavate akudega ja hübriidsüsteem. Lisaks kolmele eri süsteemile ja ärimudelile on tegemist turuga, mis ei ole standardiseeritud – linnad ja operaatorid esitavad oma kogemusele ja soovidele põhinedes nõudmised jalgratastele, mistõttu on need sageli üksteisest väga erinevad. On linnad ja asulad, kus saab opereerida ilma eriliste reeglite ja nõudmisteta ning on linnad, mis esitavad selged tingimused ja operaatorid peavad osalema hangetel, et saada opereerida oma süsteemi. There are three most common systems in the bike sharing and rental market – charging stations, swappable batteries and hybrid systems. In addition to the three different systems and business models, it is a market that is not standardized – cities and operators set requirements for bicycles based on their experience and wishes, which is why they are often very different from each other. There are cities and settlements where you can operate without any special rules and requirements, and there are cities that set clear conditions and operators have to participate in tenders to be able to operate their system.
Turul kasutatavad jalgrattad on sageli mõeldud ainult ühe kindla ärimudeliga opereerimiseks ning seetõttu saavad operaatorid tegutseda piiratud linnades. Esineb aga ka olukordi, kus ühe ja sama ärimudeli raames on linnade esitatud tingimused niivõrd erinevad, et operaator peab opereeritavates linnades kasutama erinevaid jalgrattaid. Samuti on probleemiks muutuv turg. Hankega määratud 3 kuni 5 aastase opereerimise perioodi lõppedes on linnade muutunud reeglite ja soovide tõttu keeruline samade jalgratastega uuesti samas linnas hange võita või leida sobivate tingimustega uus linn. Seetõttu ei leia operaatorid jalgratastele kiiresti uut kasutust ning tegemist on kasutamata jäänud tuludega. Selleks on vaja jalgrattaid, mis on mõeldud jalgrattaringluse ja jalgrataste renditeenuse tingimustes kasutamiseks ja oleksid kohandatavad linnade ja asulate erinevatele reeglitele ja soovidele ning kolmele eri süsteemile (ärimudelile) – lisaks olemasolevate jalgrattaringluse süsteemide jaoks. Bicycles used on the market are often designed to operate with only one specific business model, and therefore operators can operate in limited cities. However, there are also situations where, within the framework of one and the same business model, the conditions presented by the cities are so different that the operator has to use different bicycles in the cities it operates. Another problem is the changing market. At the end of the 3 to 5 year operating period specified in the tender, it is difficult to win the tender again in the same city with the same bicycles or find a new city with suitable conditions due to the changed rules and wishes of the cities. Therefore, operators do not quickly find new uses for the bicycles and this results in unused income. This requires bicycles that are designed for use in the conditions of bicycle circulation and bicycle rental services and that are adaptable to the different rules and wishes of cities and settlements and to three different systems (business models) – in addition to the existing bicycle circulation systems.
Operaatorite teine probleem on elektrijalgrataste kõrgem hind võrreldes elektritõukeratastega ning elektrijalgratastega seotud hooldus- ja parandustööd. Jalgrattaid on võrreldes elektritõukeratastega füüsiliselt keerulisem kaubikutega transportida – tulenevalt jalgratta kujust ja geomeetriast. Selleks on vaja jalgrattaid, mille kõige sagedamini vahetatavad komponendid oleksid kiirelt vahetatavad tänaval ning töökotta viiakse ainult vigane komponent või moodul, mitte kogu jalgratas. Another problem for operators is the higher price of electric bicycles compared to electric scooters and the maintenance and repair work associated with electric bicycles. Bicycles are physically more difficult to transport in vans compared to electric scooters – due to the shape and geometry of the bicycle. This requires bicycles with the most frequently replaced components that can be quickly replaced on the street and only the faulty component or module is taken to the workshop, not the entire bicycle.
Leiutis on suunatud mainitud probleemide lahendamiseks, kus operaatorid saavad opereerida modulaarset jalgratast kõigis kolmes süsteemis, kohandades seda iga The invention is aimed at solving the mentioned problems, where operators can operate a modular bicycle in all three systems, adapting it to each
süsteemi eripärade jaoks. Kasutades ainult ühte jalgratast, muutub opereerimine ja süsteemi haldamine lihtsamaks ja kuluefektiivsemaks. Operaatorid saavad tegutseda korraga mitmel erineval ärisuunal ja ei pea muretsema reeglite ja soovide muudatuste pärast. Tänaval jalgrataste hooldamine ja parandamine võimaldab vältida jalgrataste kulukat edasi-tagasi transportimist ning vähendada töökoja kulusid. Jalgrattad on minimaalselt kasutusest eemal ja saavad seeläbi teenida suuremat käivet/tulu. for the specifics of the system. By using only one bike, operation and management of the system becomes simpler and more cost-effective. Operators can operate in several different business lines at the same time and do not have to worry about changes in rules and wishes. Maintaining and repairing bicycles on the street allows you to avoid costly transportation of bicycles back and forth and reduce workshop costs. The bicycles are minimally out of use and can therefore generate higher turnover/income.
Leiutise eesmärk Purpose of the invention
Leiutise eesmärk on pakkuda välja modulaarne elektrijalgratas, mis on kohandatav kolme jalgrattaringluse ja renditeenuse süsteemi jaoks – laadimisjaamadega, vahetatavate akudega ja hübriidsüsteem – ning jalgratas, mille hooldust on võimalik mugavalt tänaval kohapeal teha. Kolme jalgrattaringluse ja renditeenuse süsteemi jaoks on vaja teha vahetatav akuplokk moodulina, mis võimaldab kasutada eri suurusega akusid, esikahvli modulaarsus, mis võimaldab kasutada jalgrattal erinevaid esikahvleid ühildumaks laadimisjaamadega alt esiratta telje kõrguselt ning kõrgemalt juhtraua alt, keskjooksu modulaarsus, mis võimaldab kasutada nii mehaanilist keskjooksu kui ka keskjooksumootorit. The aim of the invention is to provide a modular electric bicycle that is adaptable to three bicycle circulation and rental systems – with charging stations, with replaceable batteries and a hybrid system – and a bicycle that can be conveniently serviced on the street. For the three bicycle circulation and rental systems, it is necessary to make a replaceable battery pack as a module that allows the use of batteries of different sizes, front fork modularity that allows the use of different front forks on the bicycle to be compatible with charging stations below the front wheel axle height and above the handlebars, bottom bracket modularity that allows the use of both a mechanical bottom bracket and a bottom bracket motor.
Lisafunktsioonide modulaarsuseks on esikorvi modulaarsus, mis võimaldab kasutada eri suuruse ja kujuga korve (nt küljed kinni, küljed avatud) ja lasteistet; tagumise poritiiva modulaarsus, mis võimaldab paigaldada mitut tüüpi poritiibasid ning kulleritele kauba vedamiseks vastavat kasti, ekraani modulaarsus, mis võimaldab panna jalgrattale mitu ekraani koos korpusega. The modularity of additional features includes front basket modularity, which allows the use of baskets of different sizes and shapes (e.g. closed sides, open sides) and a child seat; rear fender modularity, which allows the installation of several types of fenders and a corresponding box for couriers to transport goods; screen modularity, which allows the installation of several screens on the bike with a housing.
Vahetatava aku modulaarsus tähendab, et jalgratta raamis on akuploki vastuvõtmiseks pesa kui eraldi raami komponent, mis võimaldab kinnitada sellesse mitme eri suurusega akuplokki. Olenevalt linna ja asula suurusest, on linnadel vajadus kasutada eri mahutavusega akusid, et vähendada aku vahetamisega seotud opereerimiskulusid. Akuplokk kui moodul võib käia välja raami eesotsast, külje pealt, ülevalt või alt. The modularity of the replaceable battery means that the bicycle frame has a slot for receiving the battery pack as a separate frame component, which allows for the attachment of several different sized battery packs. Depending on the size of the city and settlement, cities need to use batteries of different capacities to reduce the operating costs associated with battery replacement. The battery pack as a module can protrude from the front, side, top or bottom of the frame.
Samuti võivad akuplokk ja keskjooksumoodul olla koos ühes moodulis, mida on võimalik raamist välja võtta. Nii saab kiirelt akuploki tänaval vahetada ning isegi kui jalgratas ei ole vahetatavate akudega süsteemis kasutatav, on muudes süsteemides hoolduse ja paranduse käigus aku vahetus mugav ja kiire. The battery pack and bottom bracket module can also be combined into one module that can be removed from the frame. This allows for quick battery replacement on the road, and even if the bike is not compatible with a system with replaceable batteries, battery replacement is convenient and quick during maintenance and repair in other systems.
Esikahvli modulaarsus tähendab, et jalgrattal on võimalik kasutada olemasolevate jalgrattaringluse ja renditeenuse jalgrataste esikahvleid, millega tagatakse kohene ühildumine olemasolevate süsteemidega. Teine lahendus on samasse raami modulaarsesse lahendusse arendatud esikahvel, mille alumine osa ning juhtraua alumine osa on modulaarsed. See võimaldab vahetada esikahvlil väikse komponendi ning panna jalgratas füüsiliselt ühilduma eri laadimisjaamadesse. Ühe näitena esikahvli esiratta teljel on liides, mille lisamisega ühildub jalgratas laadimisjaamadesse esiratta telje kõrguselt. Teise näitena on juhtraua pikendus modulaarne, millega jalgratas ühildub füüsiliselt juhtraua alt laadimisjaamaga. Enda arendatud modulaarsel esikahvlil on võimalik seetõttu tänaval ära vahetada esikahvli alumine või ülemine liides, kui selle elektriühendused on korrodeerunud või kui muul juhul ei toimi jalgratta laadimine enam ettenähtud korras. The modularity of the front fork means that the bicycle can use the front forks of existing bicycle circulation and rental bicycles, which ensures immediate compatibility with existing systems. Another solution is a front fork developed in the same frame modular solution, the lower part of which and the lower part of the handlebar are modular. This allows you to change a small component on the front fork and make the bicycle physically compatible with different charging stations. As one example, the front fork has an interface on the front wheel axle, with the addition of which the bicycle is compatible with charging stations at the height of the front wheel axle. As another example, the handlebar extension is modular, with which the bicycle is physically compatible with the charging station under the handlebar. With a modular front fork developed in-house, it is therefore possible to replace the lower or upper interface of the front fork on the street if its electrical connections are corroded or if the bicycle is otherwise no longer charging as intended.
Keskjooksu modulaarsus tähendab, et jalgrattal on eraldiseisev modulaarne raami komponent ehk nn keskjooksumoodul, mille küljes on keskjooksumootor või mehaaniline keskjooks. Operaator saab kasutada ühte ja sama jalgratast linnades ja asulates, mis nõuavad hübriidsüsteemi - elektrijalgrattad ja tavarattad. Samuti on keskjooksumoodulis võimalik kasutada mitut erinevat keskjooksumootorit. Keskjooksumooduli saab teostada raamist väljakäivana alt, küljelt või ülevalt. Nii on võimalik tänaval võtta keskjooksumootori rikke korral ainult keskjooksumoodul ning viia see töökotta – rattal asendatakse kohe tänaval rikkis keskjooksumoodul uuega. Teine kasutusjuhtum on vahetada tänaval sügisel enne talveperioodi keskjooksumoodul mehaanilise keskjooksumooduli vastu ning jalgrattad on kasutatavad aastaringselt ilma töökotta viimata. The modularity of the bottom bracket means that the bicycle has a separate modular frame component, or so-called bottom bracket module, with a bottom bracket motor or mechanical bottom bracket attached to it. The operator can use the same bicycle in cities and towns that require a hybrid system - electric bicycles and conventional bicycles. It is also possible to use several different bottom bracket motors in the bottom bracket module. The bottom bracket module can be made to exit the frame from the bottom, side or top. This way, in the event of a bottom bracket motor failure on the street, it is possible to take only the bottom bracket module and take it to the workshop - the faulty bottom bracket module on the bike is immediately replaced with a new one on the street. Another use case is to replace the bottom bracket module with a mechanical bottom bracket module on the street in the fall before the winter period, and the bicycles can be used all year round without taking it to the workshop.

The bicycle frame according to the invention is designed as a so-called low open frame (also known as an “open frame”, “step through” or “drop frame”), which in a side view of the frame comprises a generally straight main frame part, which, at least in the bottom bracket area, has a downwardly open U-shaped cross-section in use.
Raami põhiosa ühes otsas (st ratta sõidu suunas raami esiotsas) on raami põhiosa suhtes nurga all olev diagonaaltoru, mille teises otsas on esitoru esikahvli vastuvõtmiseks. Raami põhiosa teise otsa (st ratta sõidu suunas raami tagaosas) on moodustatud põhiosa külgedelt eenduva kahe paralleelse tugiprofiiliga tagakahvel. At one end of the main frame (i.e. at the front end of the frame in the direction of travel of the bicycle) is a diagonal tube angled to the main frame, at the other end of which is a front tube for receiving the front fork. At the other end of the main frame (i.e. at the rear of the frame in the direction of travel of the bicycle), a rear fork is formed with two parallel support profiles projecting from the sides of the main part.

Leiutise teostusnäited Embodiments of the invention
Selguse huvides on eri joonistel samad detailid ja elemendid tähistatud samade viitenumbritega. For the sake of clarity, the same details and elements in different drawings are designated by the same reference numerals.
Joonistel fig 1 ja 2 kujutatud jalgratas 1 sisaldab raami 2, milles on esikahvlit 3 vastu võttev esitoru 4 raami 2 esiosaga 5 ühendatud diagonaaltoruga 6. Raami 2 tagaosas on tagakahvel 7, mille vahel asetseb tagaratas 8, mida ümbritseb tagumine porilaud The bicycle 1 shown in Figures 1 and 2 comprises a frame 2 in which a front tube 4 receiving a front fork 3 is connected to the front part 5 of the frame 2 by a diagonal tube 6. At the rear of the frame 2 is a rear fork 7, between which is located a rear wheel 8, which is surrounded by a rear mudguard.
9. Raami 2 esitorusse 4 on pööratavalt ühendatud esikahvel, millesse on pöörlevalt kinnitatud esiratas 10. Esikahvliga 3 on ühendatud kõrgendustoru 11 abil juhtraud 12 ratta juhtimiseks. 9. A front fork is rotatably connected to the front tube 4 of the frame 2, to which a front wheel 10 is rotatably attached. A handlebar 12 for steering the wheel is connected to the front fork 3 by means of a riser tube 11.
Raami 2 U-kujulise ristlõikega põhiosasse 13 on sisestatud keskjooksumoodul 14, mis sisaldab vändavõlli (ei ole eraldi näidatud) otstes pedaalidega 15 väntasid 16 – vt joonis fig 4. A bottom bracket module 14 is inserted into the main part 13 of the frame 2 with a U-shaped cross-section, which includes a crank shaft (not shown separately) with pedals 15 at the ends, cranks 16 - see figure 4.
Kujutatud teostuses sisaldab esikahvel 3 laadimisjaamaga ühenduselemente 17. Samuti on jalgratas varustatud eesmise korviga 18. Juhtraual 12 asetseb elektrijalgratta näidikutega juhtmoodul 19 – vt joonis fig 3. In the illustrated embodiment, the front fork 3 includes connection elements 17 with the charging station. The bicycle is also equipped with a front basket 18. The handlebar 12 houses a control module 19 with electric bicycle indicators – see figure 3.
Kujutatud teostuses asetseb akuplokk 20 (st akumoodul) raami 2 esiosas 5 ning on eemaldatav raamis olevast pesast raami 2 otsast. In the illustrated embodiment, the battery pack 20 (i.e., the battery module) is located in the front part 5 of the frame 2 and is removable from a slot in the frame at the end of the frame 2.
Raamist 2 eendub sadulatoru 21 sadulaga 22 sadulaposti 23 vastuvõtmiseks. Joonistel kujutatud raamis 2 on diagonaaltoru 6 teostatud kaarja toruna, ent see võib olla ka sirge profiil. A seat tube 21 with a saddle 22 projects from the frame 2 to receive a seat post 23. In the frame 2 shown in the figures, the diagonal tube 6 is designed as a curved tube, but it can also be a straight profile.
Nagu jooniselt fig 4 on näha, on raami 2 põhiosa 13 U-kujulise profiiliga, mis on allapoole avatud. Raam 2 sisaldab selles kohas sisselõikeid 24 vändavõlli vastuvõtmiseks, millel asetseb ka vedav ülekanderatas 25, kujutatud teostuses ketiratas, millel asetseb painduv jõuülekandeelement 26, kujutatud teostuses kett. Joonistel fig 4, 5 ja 7 kujutatud olukorras on keskjooksumoodul 14 raami 2 põhiosast 13 välja nihutatud. As can be seen from Figure 4, the main part 13 of the frame 2 has a U-shaped profile that is open downwards. The frame 2 includes cutouts 24 at this point for receiving a crank shaft, on which a drive transmission wheel 25 is also located, in the illustrated embodiment a sprocket wheel, on which a flexible power transmission element 26 is located, in the illustrated embodiment a chain. In the situation shown in Figures 4, 5 and 7, the bottom bracket module 14 is displaced from the main part 13 of the frame 2.
Joonistelt fig 7 ja 8 on samuti näha keskjooksumoodulis 14 sisalduv keskjooksumootor 27, mis on kogu keskjooksumooduliga 14 nooltega näidatud suunas nihutatav raami 2 põhiossa 13, mis sisaldab vändavõlli otstele sisselõikeid 24. Selline konfiguratsioon võimaldab keskjooksumoodulit 14 vahetada ka ilma tagaratast 8 eemaldamata. Figures 7 and 8 also show the bottom bracket motor 27 included in the bottom bracket module 14, which can be moved with the entire bottom bracket module 14 in the direction indicated by the arrows into the main part 13 of the frame 2, which includes cuts 24 at the ends of the crankshaft. Such a configuration allows the bottom bracket module 14 to be replaced without removing the rear wheel 8.
Joonistel fig 9, 10 ja 11 on näidatud raami 2 esiosas 5 oleva akuploki 20 paiknemist raami moodustatud pesas. Joonistel kujutatud teostusele lisaks võib akuploki eemaldamise raamist ja raami paigaldamise teha raami alt, pealt või küljelt. Figures 9, 10 and 11 show the location of the battery pack 20 in the front part 5 of the frame 2 in the slot formed by the frame. In addition to the embodiment shown in the figures, the battery pack can be removed from the frame and the frame can be installed from the bottom, top or side of the frame.
Leiutise joonistel fig 3 kuni 10 kujutatud teostuses on raam 2 valmistatud alumiiniumisulamist profiilidest. Raami 2 esiosa 5 ja põhiosa 13 on moodustatud U-kujulise profiilina, mis on allapoole avatud. Raami 2 esiossa 5 keevitatakse diagonaaltoru 6, In the embodiment of the invention shown in Figures 3 to 10, the frame 2 is made of aluminum alloy profiles. The front part 5 and the main part 13 of the frame 2 are formed as a U-shaped profile that is open downwards. A diagonal tube 6 is welded to the front part 5 of the frame 2,
mille otsa omakorda esitoru 4. Samuti keevitatakse põhiosa 13 külge sadulatoru 21. to the end of which in turn is the front tube 4. Also, the seat tube 21 is welded to the main part 13.
Kujutatud teostuses on näidatud ka täiendavad jäikust lisavad toed raami 2 esiosa 5 ja diagonaaltoru 6 vahel ning sadulatoru 21 ja raami 2 vahel, ent raam 2 võib olla teostatud ka ilma nendeta. The illustrated embodiment also shows additional stiffening supports between the front part 5 of the frame 2 and the diagonal tube 6 and between the seat tube 21 and the frame 2, but the frame 2 can also be made without them.
Tagakahvel 7 on moodustatud jätkuna raami 2 põhiosast 13 eenduva kahe paralleelse profiilina. Akuploki 20 jaoks on raami 2 esiosa 5 tehtud altvaates kinnisena, st raami 2 esiosas 5 on akuplokile 20 pesa. Keskjooksumooduli 14 vastuvõtmiseks on raami 2 põhiosas 13 keskjooksumoodulis 14 sisalduvale vändavõllile sisselõiked 24. Sadulatoru 21 on tehtud suurendatud läbimõõduga, milles on eraldi peenem toru sadulaposti 23 vastuvõtmiseks. Muu ruum sadulapostis 21 on kasutatav täiendava elektroonikaploki või akuploki mahutamiseks. Kujutatud teostuses on sadulatoru 21 ülaosas jalgratta tagatuli. The rear fork 7 is formed as a continuation of the main part 13 of the frame 2 as two parallel profiles projecting from the main part 13. For the battery pack 20, the front part 5 of the frame 2 is made closed in the bottom view, i.e. the front part 5 of the frame 2 has a slot for the battery pack 20. To receive the bottom bracket module 14, the main part 13 of the frame 2 has cuts 24 for the crank shaft contained in the bottom bracket module 14. The seat tube 21 is made with an increased diameter, in which there is a separate thinner tube for receiving the seat post 23. The other space in the seat post 21 is used to accommodate an additional electronics unit or battery pack. In the illustrated embodiment, the rear light of the bicycle is located at the top of the seat tube 21.
Selline nn madal avatud jalgratta raam 2 võimaldab konfigureerida jalgratast eri disaini ja konstruktsiooniga porilaudadega, kasutada sel eri tüüpi jalatugesid, pidureid, tulesid ja korve 18. Such a so-called low open bicycle frame 2 allows the bicycle to be configured with fenders of different designs and constructions, and to use different types of footrests, brakes, lights and baskets 18.
Tööstuslik kasutatavus Industrial usability
Jalgrattaringluse ja renditeenuse jalgrattad asuvad linna või asula tänavatel, kas vabalt laenutatavatena või kindlates laadimisjaamades, parkimisaladel. Operaator kasutab tarkvara, millega on võimalik jälgida ja kontrollida jalgrataste seisukorda. Keskjooksumootori vea korral võtab operaatori hooldusmeeskonna liige töökojast töötava keskjooksumootori koos raami mooduliga ning sõidab jalgratta asukohta. Tänaval keeratakse jalgrattal keskjooksumooduli kinnituspoldid lahti ning võetakse keskjooksumoodul raami küljest ära. Bicycles for bicycle circulation and rental services are located on the streets of a city or settlement, either freely available for loan or at specific charging stations or parking areas. The operator uses software that allows monitoring and checking the condition of the bicycles. In the event of a bottom bracket motor fault, a member of the operator's maintenance team takes a working bottom bracket motor with the frame module from the workshop and drives to the location of the bicycle. On the street, the bottom bracket module fastening bolts are unscrewed from the bicycle and the bottom bracket module is removed from the frame.
Seejärel pannakse töökojast kaasa võetud töökorras keskjooksumoodul asemele ja keeratakse kinnituspoldid kinni. Jalgratas ei vaja transporti töökotta ja on kasutusest eemal ainult mooduli vahetuse aja. Hooldustöid teinud inimene võtab mittetöötava mooduli kaasa ning töökojas tehakse moodulile (keskjooksumootorile) diagnostika ja põhjalik kontroll valideerimaks, kas moodulit on võimalik parandada ja uuesti kasutada. Olenevalt tulemusest läheb parandatud moodul kasutatavaks varuosaks või utiliseerimisele. Then, the working bottom bracket module brought from the workshop is replaced and the fastening bolts are tightened. The bicycle does not need to be transported to the workshop and is only out of use for the duration of the module replacement. The person who performed the maintenance work takes the non-working module with him and the module (bottom bracket motor) is subjected to diagnostics and a thorough check in the workshop to validate whether the module can be repaired and reused. Depending on the result, the repaired module is either used as a spare part or disposed of.
Süsteemi kuuluvad jalgratta raam, vahetatav akuplokk (akumoodul), keskjooksumoodul, milles on keskjooksumootor, vändad, pedaalid, või keskjooksumootorit asendav mehaaniline keskjooks. The system includes a bicycle frame, a replaceable battery pack (battery module), a bottom bracket module containing a bottom bracket motor, cranks, pedals, or a mechanical bottom bracket replacing the bottom bracket motor.
Jalgrattaringluse ja renditeenuse jalgrattad asuvad linna või asula tänavatel, kas vabalt laenutatavatena või kindlates laadimisjaamades, parkimisaladel. Operaatoritel, kes opereerivad aastaringselt, on vaja jalgrattad sügisel talveperioodiks ette valmistada. Akuplokk ja keskjooksumootorit (elektrimootorit) sisaldav keskjooksumoodul võetakse talveperioodiks ära ja asendatakse ainult mehaanilist keskjooksu sisaldava keskjooksumooduliga, st selles konfiguratsioonis on tegemist nn tavalise jalgrattaga, mis liigub edasi ainult kasutaja lihasjõul. Bicycles for bike sharing and rental services are located on the streets of a city or town, either freely available for loan or at specific charging stations, parking areas. Operators who operate all year round need to prepare their bicycles for the winter period in the autumn. The battery pack and the bottom bracket module containing the bottom bracket motor (electric motor) are removed for the winter period and replaced with a bottom bracket module containing only a mechanical bottom bracket, i.e. in this configuration it is a so-called regular bicycle, which moves forward only on the user's muscular strength.
Operaatori hooldusmeeskonna liige võtab töökojast ainult mehaanilist keskjooksu sisaldava keskjooksumooduli ja sõidab jalgratta asukohta. Tänaval keerab ta jalgrattal keskjooksumooduli kinnituspoldid lahti ning eemaldab selle raamist. A member of the operator's maintenance team takes a bottom bracket module containing only a mechanical bottom bracket from the workshop and drives to the location of the bicycle. On the street, he unscrews the bottom bracket module's mounting bolts and removes it from the frame.
Asemele pannakse töökojast kaasa võetud mehaanilise keskjooksuga keskjooksumoodul ning keeratakse kinnituspoldid kinni. Seega ei vaja jalgratas transporti töökotta ja on kasutusest eemal ainult keskjooksumooduli vahetuse aja. A bottom bracket module with a mechanical bottom bracket taken from the workshop is installed in its place and the mounting bolts are tightened. This means that the bicycle does not need to be transported to the workshop and is only out of use for the duration of the bottom bracket module replacement.
Samuti võetakse vahetatav akuplokk ära ja tavalise mehaanilise jalgratta korral ei ole vaja midagi asemele panna. Hooldustöid teinud inimene võtab keskjooksumooduli ja akuploki ning töökojas tehakse neile (keskjooksumootorile ja akule) diagnostika ja põhjalik kontroll, valideerimaks nende seisukorda. Olenevalt tulemusest lähevad hooldatud keskjooksumoodul ja akuplokk kasutatavaks varuosaks või utiliseerimisele. The battery pack that is to be replaced is also removed, and in the case of a regular mechanical bicycle, nothing needs to be replaced. The person who performed the maintenance takes the bottom bracket module and the battery pack, and they (the bottom bracket motor and the battery) are given a diagnostic and thorough check in the workshop to validate their condition. Depending on the result, the serviced bottom bracket module and battery pack are either used as spare parts or disposed of.
Jalgrattaringluse ja renditeenuse operaator opereerib algselt vahetatavate akudega elektrijalgratast linnas, mis ei sea opereerimisele erilisi tingimusi ega reegleid. Teenuse suure kasutatavuse ja laienemise tagajärjel on tõenäoline, et linnad ja asulad soovivad turgu osaliselt reguleerida ning korraldavad vastavad hanked. Sagedane tingimus on laadimisjaamadega rattaringlus. The bike sharing and rental service operator initially operates electric bicycles with replaceable batteries in the city, which does not impose any special conditions or rules on the operation. As a result of the high usability and expansion of the service, it is likely that cities and towns will want to partially regulate the market and organize corresponding procurements. A common condition is bike sharing with charging stations.
Operaator lisab elektrijalgratta esihargile modulaarse komponendi, mis ühildub laadimisjaamaga esiratta telje kõrguselt või vahetab modulaarse juhtraua kõrgenduse, mis ühildub laadimisjaamaga juhtraua alt - vastavalt sellele, millise laadimisjaama linna või asula tingimuseks seavad. The operator adds a modular component to the front fork of the electric bicycle that is compatible with the charging station at the height of the front wheel axle or changes the modular handlebar riser that is compatible with the charging station below the handlebar - depending on which charging station the city or town sets as a condition.
Operaator saab kohandada samad elektrijalgrattad uute tingimuste ja muutunud The operator can adapt the same electric bicycles to new conditions and changed
soovide jaoks ning osaleda korraldatud hankel ja jätkata linnas või asulas opereerimist. Välditakse kahjumlikku perioodi, mis teisel juhul tekiks, kui operaator otsib ainult vahetatavate akudega elektrijalgrataste kasutusvõimalusi teistes linnades. for wishes and to participate in the organized procurement and continue operating in the city or settlement. This avoids a loss-making period that would otherwise occur if the operator only looked for opportunities to use electric bicycles with replaceable batteries in other cities.
