Abstract
Description
Die Erfindung bezieht sich auf eine Sicherheitsvorrichtung zur Abschaltung einer Fahrzeugbatterie gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a safety device for Switching off a vehicle battery according to the preamble of Claim 1.
Es ist bereits eine gattungsgemäße Sicherheitsvorrichtung be kannt (DE 26 35 264 Al), welche mittels eines bei einem Unfall automatisch ausgelösten mechanischen Kontaktunterbrechers die Batterie vom Bordnetz trennt, um einen Fahrzeugbrand durch Kurzschluß zu verhindern. Der Kontaktunterbrecher ist außen an der Batterie angebracht und reagiert auf eine unfalltypische Verzögerung.It is already a generic safety device be knows (DE 26 35 264 Al), which by means of an accident automatically triggered mechanical contact breaker Battery disconnects from on-board electrical system to cause a vehicle fire To prevent short circuit. The contact breaker is on the outside attached to the battery and reacts to a typical accident Delay.
Weiterhin ist aus der DE 37 20 242 A1 eine Sicherheitsvorrichtung bekannt, bei der eine unfallbedingte Batterieabschaltung durch einen am Batteriepol angebrachten Unterbrecher erfolgt, der mittels eines Zugseils betätigt wird. Das Zugseil ist an Karosseriebauteilen befestigt und wird so verlegt, daß eine Verformung innerhalb der Knautschzone im vorderen Bereich des Fahrzeugs eine Straffung des Zugseils und damit eine Betätigung des Unterbrechers bewirkt.Furthermore, DE 37 20 242 A1 discloses a safety device in which one the battery is switched off by an interrupter attached to the battery pole, which is operated by means of a pull rope. The pull rope is attached to body components and is laid so that a deformation within the crumple zone in the front of the vehicle tightens the pull rope and thus actuates the breaker.
Nachteilig an den bekannten Sicherheitsvorrichtungen ist, daß sie bei unfallbedingten inneren Kurzschlüssen einer aus mehreren Zellen aufgebauten Batterie nicht verhindern können, daß trotz Abschaltung der äußeren Last alle im inneren Kurzschußkreis liegenden Zellen ihre chemische Energie abgeben. Insbesondere bei Hochenergiebatterien, wie sie für Elektrofahrzeuge eingesetzt werden, kann die freiwerdende Energie so groß sein, daß durch starke Erwärmung der Batterie oder Funken ein Fahrzeugbrand verursacht wird.A disadvantage of the known safety devices is that in the event of an accident-related interior Short circuits of a battery made up of several cells cannot prevent that despite Shutdown of the external load, all cells in the inner short circuit have their chemical Give up energy. Particularly in the case of high-energy batteries, such as those used for electric vehicles be released energy can be so large that due to strong heating of the battery or spark a vehicle fire is caused.
Aufgabe der Erfindung ist es, eine Sicherheitsvorrichtung zu schaffen, welche eine unfallbedingte innere Kurzschlußleistung bei einer aus mehreren Zellen zusammengesetzten Fahrzeugbatte rie begrenzt. The object of the invention is to provide a safety device create which an accident-related internal short-circuit performance for a vehicle battery composed of several cells limited.
Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Pa tentanspruchs 1 gelöst. Besondere Aus- und Weiterbildungen sind durch die Merkmale der Unteransprüche gekennzeichnet.This task is carried out with the characteristic features of Pa claim 1 solved. Special training and further education are characterized by the features of the subclaims.
Es werden zwei Ausführungsbeispiele angegeben, die sich durch die Art der Auslösung der Kontaktunterbrecher unterscheiden.Two exemplary embodiments are given, which are characterized by differentiate the type of triggering of the contact breaker.
Das erste Ausführungsbeispiel, bei dem die Kontaktunterbrecher als unabhängige, bei einer unfalltypischen Verzögerung auslö sende Einheiten aufgebaut sind, ermöglicht bei gleicher äußerer Gestaltgebung der Einheiten wie die Zellen, die Einheiten an beliebiger Stelle in den Zellenverband im Batteriekasten zu integrieren. In vorteilhafter Weise braucht beim Entwurf eines Batteriekastens nicht auf einen eventuellen Einbau von Kon taktunterbrechern Rücksicht genommen werden, da diese sich in ihrer äußeren Form und Verschaltung nicht von den Zellen un terscheiden.The first embodiment in which the contact breaker as an independent, trigger in the event of a typical delay transmitting units are built, allows for the same outer Design of the units like the cells, the units anywhere in the cell cluster in the battery box integrate. Advantageously, when designing a Battery box not for a possible installation of Kon clock interrupters are taken into account, as these are in their external shape and interconnection do not differ from the cells differentiate.
Im zweiten Ausführungsbeispiel werden die Kontaktunterbrecher von einem gemeinsamen Auslösegerät betätigt, welches auf Verzö gerung und auf Zug an einem Zugseil reagiert. In vorteilhafter Weise kann damit, bei geeigneter Verlegung des Zugseils, die Betätigung der Kontaktunterbrecher durch eine unfallbedingte Verformung am Fahrzeug ausgelöst werden.In the second embodiment, the contact breakers operated by a common trigger device, which on delay and reacted to train on a pull rope. In advantageous Thus, with suitable laying of the pull rope, the Operation of the contact breaker by an accident-related Deformation can be triggered on the vehicle.
Die Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden im folgenden näher beschrieben. Es zei gen:The embodiments of the invention are in the drawing are shown and are described in more detail below. It shows gene:
Fig. 1 eine Fahrzeugbatterie mit der erfindungsgemäßen Sicherheitsvorrichtung, FIG. 1 a vehicle battery with the inventive safety device
Fig. 2 ein Ausführungsbeispiel für ein erfindungsgemäßes Auslösegerät. Fig. 2 shows an embodiment of a trigger device according to the invention.
Die Fahrzeugbatterie in der Fig. 1 besteht aus einem Batterie kasten 1 mit mehreren elektrochemischen Zellen 2, welche durch Leiterbrücken 3 in Reihe geschaltet sind. Anfang und Ende der Reihe bilden den Minuspol 5 bzw. den Pluspol 4 der Batterie.The vehicle battery in Fig. 1 consists of a battery box 1 with a plurality of electrochemical cells 2 , which are connected in series by conductor bridges 3 . The negative pole 5 and the positive pole 4 of the battery form the beginning and end of the row.
Eine (unfallbedingte) äußere Krafteinwirkung 6 auf den Batte riekasten 1 kann diesen verformen und unter Umständen einen inneren Kurzschluß der Batterie hervorrufen. Dabei können meh rere in Reihe geschaltete Zellen 2 einen Kurzschlußkreis bil den. Erfindungsgemäß sind daher mehrere, in den Ausführungs beispielen zwei Kontaktunterbrecher 7 vorgesehen, durch die der Stromweg im Kurzschlußstromkreis bei einem Unfall automatisch unterbrochen wird.An (accident-related) external force 6 on the battery cabinet 1 can deform it and possibly cause an internal short circuit of the battery. Several cells 2 connected in series can form a short-circuit circuit. According to the invention, therefore, several, in the execution examples two contact breakers 7 are provided, through which the current path in the short-circuit circuit is automatically interrupted in an accident.
Im ersten Ausführungsbeispiel sind die Kontaktunterbrecher 7 als mechanische Unterbrecher ausgebildet, die in an sich be kannter Weise selbsttätig bei einer vorbestimmten Beschleuni gung auslösen. Ein solcher Kontaktunterbrecher ist beispiels weise in der DE 26 35 264 A1 beschrieben. Dieser Schrift fol gend wird mittels einer Kugel, die durch eine Druckbuchse mit einer Druckfeder gehalten wird, im Normalbetrieb ein Stromfluß ermöglicht, der bei einer durch die Stärke der Druckfeder vorgegebenen Beschleunigung durch Freigabe der Kugel unterbro chen wird. Vorzugsweise sind die Kontaktunterbrecher 7 in einem Gehäuse untergebracht, welches in das durch die Zellen 2 ge bildete Raster paßt. Bei einer Unterbringung der Kontaktunter brecher 7 in einem gleichen Gehäuse (nicht dargestellt) wie das der Zellen 2 ist es möglich, einen kompakten Zellverband auf zubauen, bei dem an beliebigen Stellen eine Zelle 2 durch einen Kontaktunterbrecher 7 ersetzt werden kann. In the first embodiment, the contact breaker 7 are designed as mechanical breakers, which automatically trigger in a manner known per se at a predetermined acceleration. Such a contact breaker is described, for example, in DE 26 35 264 A1. This font fol lowing is by means of a ball, which is held by a pressure bush with a compression spring, allows a current flow in normal operation, which is interrupted at a predetermined by the strength of the compression spring acceleration by releasing the ball. Preferably, the contact breaker 7 are housed in a housing which fits into the grid formed by the cells 2 ge. When the contact breaker 7 is accommodated in the same housing (not shown) as that of the cells 2 , it is possible to build a compact cell assembly in which a cell 2 can be replaced at any point by a contact breaker 7 .
In dem zweiten Ausführungsbeispiel werden die Kontaktunterbre cher 7 von einem Auslösegerät 8 mittels eines Betätigungsmit tels 9 - beispielsweise einer Verbindungsstange, elektrischer oder hydraulischer Mittel - betätigt. Das Auslösegerät 8 ist so ausgebildet, daß die Betätigung der Kontaktunterbrecher 7 so wohl bei einer vorbestimmten Beschleunigung als auch durch Zug an einem Zugseil 10 ausgelöst wird.In the second exemplary embodiment, the contact interrupters 7 are actuated by a trigger device 8 by means of an actuating means 9 - for example a connecting rod, electrical or hydraulic means. The trigger device 8 is designed so that the actuation of the contact breaker 7 is triggered at a predetermined acceleration as well as by pulling on a pull rope 10 .
Das Zugseil 10 dient dazu, eine unfallbedingte Deformation am Fahrzeug auf mechanischem Wege dem Auslösegerät 8 zu melden. In dem Ausführungsbeispiel ist das Zugseil 10 über Umlenkrollen oder -führungen 11 um drei Ecken des Batteriekastens 1 herum geführt und an der letzten Ecke 12 am Batteriekasten 1 befes tigt. Bei einer äußeren Krafteinwirkung 6 auf eine Seite des Batteriekastens 1 wird daher das Zugseil 10, welches auch als Zugband ausgeführt sein kann, gestrafft, wodurch das Auslöse gerät 8 über das Betätigungsmittel 9 die Kontaktunterbrecher 7 auslöst.The pull rope 10 serves to mechanically report an accident-related deformation on the vehicle to the release device 8 . In the embodiment, the traction cable 10 via guide rollers or guides 11 at three corners of the battery case 1 and led around to the last corner 12 of the battery case 1 buildin Untitled. With an external force 6 on one side of the battery box 1 , the pull cable 10 , which can also be designed as a drawstring, is therefore tightened, as a result of which the triggering device 8 triggers the contact breaker 7 via the actuating means 9 .
Es sind andere Varianten zur Verlegung des Zugseils 10 im Fahrzeug leicht denkbar. Beispielsweise kann das Zugseil 10 so geführt werden, daß eine Verformung charakteristischer Trag strukturelemente des Fahrzeugs, z. B. innerhalb der Knautschzone im vorderen Bereich des Fahrzeugs, eine Straffung des Zugseils 10 und damit eine Auslösung der Kontaktunterbrecher 7 bewirkt.Other variants for laying the pull rope 10 in the vehicle are easily conceivable. For example, the traction rope 10 can be guided so that a deformation of characteristic supporting structural elements of the vehicle, for. B. within the crumple zone in the front of the vehicle, a tightening of the pull rope 10 and thus triggers the contact breaker 7 .
Die Fig. 2 zeigt ein Ausführungsbeispiel zu einem erfindungs gemäßen Auslösegerät 8, welches im Bereitschaftszustand darge stellt ist. Als Betätigungsmittel zur Betätigung der Kontakt unterbrecher 7 wird eine Verbindungsstange 9 eingesetzt. Im Inneren eines geschlossenen Gehäuses 13 ist ein Betätigungs riegel 14 angeordnet, der über eine Kugel 18 und einen Entrie gelungsbolzen 19 in einer Lage festgehalten wird, bei der eine Riegelfeder 15 gespannt ist und die Verbindungsstange 9 am Einrücken in das Gehäuse 13 durch eine Riegelnase 17 gehindert wird. An einem Entriegelungsstift 20, welcher durch Einrasten in eine Bohrung den Entriegelungsbolzen 19 in seiner Lage festhält, ist außerhalb des Gehäuses 13 das Zugseil 10 befe stigt. Fig. 2 shows an embodiment of a trigger device 8 according to the Invention, which is in the standby state Darge. A connecting rod 9 is used as the actuating means for actuating the contact breaker 7 . Inside a closed housing 13 , an actuating bolt 14 is arranged, the gelungsbolzen 19 is held in a position by means of a ball 18 and an unlocking device, in which a locking spring 15 is tensioned and the connecting rod 9 on engagement with the housing 13 by a locking lug 17th is prevented. On an unlocking pin 20 , which holds the unlocking bolt 19 in position by latching into a bore, the pull cable 10 is attached to the outside of the housing 13 .
Wenn der Entriegelungsstift 20 durch Zug am Zugseil 10, ent gegen der Federkraft einer Entriegelungsstiftfeder 21, den Entriegelungsbolzen 19 freigibt, kann der Betätigungsriegel 14 der Federkraft der gespannten Riegelfeder 15 nachgeben und be wegt sich abwärts. Die Abwärtsbewegung hält solange an, bis die Riegelnase 17 an den Nasenanschlag 23 schlägt. Mit der Abwärts bewegung gibt die Riegelnase 17 der durch die Federkraft einer gespannten Verbindungsstangenfeder 16 einwärts bewegten Ver bindungsstange 9 den Weg frei. Die in der Fig. 2 eingezeich neten Pfeile zeigen die Bewegungsrichtung des durch einen Zug am Zugseil 10 ausgelösten Bewegungsablaufes, welcher zu einer Betätigung der Verbindungsstange 9 und damit zu der weiter oben beschriebenen Kontaktunterbrechung führt.When the unlocking pin 20 releases the unlocking bolt 19 by tension on the pull rope 10 , ent against the spring force of an unlocking pin spring 21 , the actuating bolt 14 can yield to the spring force of the tensioned locking spring 15 and moves downward. The downward movement continues until the locking nose 17 strikes the nose stop 23 . With the downward movement, the locking lug 17 of the connecting rod 9 moved inward by the spring force of a tensioned connecting rod spring 16 opens the way. The arrows marked in FIG. 2 show the direction of movement of the movement sequence triggered by a pull on the pull rope 10 , which leads to an actuation of the connecting rod 9 and thus to the contact interruption described above.
Nach einer Auslösung des Auslösegerätes 8 ragt ein Teil des Entriegelungsbolzens 19 durch eine Öffnung 22 im unteren Teil des Gehäuses 13. Durch manuelles Zurückdrücken des herausra genden Teils des Entriegelungsbolzens 19 kann dieser wieder in seine Ausgangslage gebracht werden, bei der der Entriegelungs stift 20 einrastet, sobald das Zugseil 10 der Entriegelungs stiftfeder 21 nachgeben kann. Damit kann das Auslösegerät 8, beispielsweise nach einem Funktionstest zur Zugseilauslösung, erneut in Bereitschaftsstellung versetzt werden.After the triggering device 8 has been triggered, part of the unlocking bolt 19 projects through an opening 22 in the lower part of the housing 13 . By manually pushing back the part of the unlocking bolt 19 , this can be returned to its starting position, in which the unlocking pin 20 engages as soon as the pull cable 10 of the unlocking pin spring 21 can yield. The triggering device 8 can thus be put into the ready position again, for example after a function test for pulling the cable.
Die Kugel 18 ist im Bereitschaftszustand zwischen Betätigungs riegel 14 und dem Entriegelungsbolzen 19 eingespannt. Bei einer starken Beschleunigung oder Verzögerung in Fahrtrichtung oder Querrichtung 24 weicht bei Überschreitung eines durch die Stärke der Riegelfeder 15 bestimmten Grenzwertes die Kugel 18 aufgrund ihrer trägen Masse aus und gibt den Betätigungsriegel 14 frei, durch dessen Abwärtsbewegung wiederum die Verbindungs stange 9 betätigt wird. Damit sind die Kontaktunterbrecher 7 auch bei einer unfalltypischen Verzögerung oder Beschleunigung auslösbar.The ball 18 is clamped in the ready state between the actuating bolt 14 and the unlocking bolt 19 . With a strong acceleration or deceleration in the direction of travel or transverse direction 24 , the ball 18 dodges when a limit value determined by the strength of the locking spring 15 is exceeded and releases the actuating bolt 14 , by the downward movement of which the connecting rod 9 is in turn actuated. The contact breakers 7 can thus be triggered even in the event of a deceleration or acceleration typical of an accident.
Um das Auslösegerät 8 nach einer Auslösung durch Ausweichen der Kugel 18 wieder in Bereitschaftsstellung zu versetzen, muß bei gezogenem Entriegelungsstift 20 der Entriegelungsbolzen 19 von Hand, durch Zug an dem aus der Öffnung 22 herausragenden Teil, nach unten gezogen werden, worauf die Kugel, der Schwerkraft folgend, die ursprüngliche Lage in der Mulde auf dem Ent riegelungsbolzen 19 einnimmt. Danach kann der Entriegelungs bolzen 19 zusammen mit dem Betätigungsriegel 14 eingedrückt werden, bis der Entriegelungsstift 20 einschnappt und den Ent riegelungsbolzen 19 in Bereitschaftsstellung fixiert.In order to set the trigger device 8 back into standby position after triggering by dodging the ball 18 , the unlocking pin 19 must be pulled down manually by pulling on the part protruding from the opening 22 when the unlocking pin 20 is pulled, after which the ball, the Following gravity, the original position in the trough on the unlocking bolt 19 assumes. Then the unlocking bolt 19 can be pressed in together with the actuating bolt 14 until the unlocking pin 20 snaps in and the unlocking bolt 19 is fixed in the ready position.
