Ausführungsformen der Erfindung stellen ein Schloss für eine Fahrzeugtür zur Verfügung, welches mindestens eine mit einem ersten Antrieb koppelbare Öffnungsmechanik, eine Kupplung, welche von mindestens einem manuellen Betätigungselement mechanisch in einen kraftübertragenden Zustand überführbar ist und im kraftübertragenden Zustand die mindestens eine Öffnungsmechanik mit dem ersten Antrieb (20) koppelt, einen mit einem Sicherungselement gekoppelten zweiten Antrieb, wobei das Sicherungselement in einer ersten stationären Stellung eine manuelle Betätigung über ein Innenbetätigungselement sperrt, und eine Auswerte- und Steuereinheit umfasst, welche korrespondierende Steuersignale an den ersten Antrieb und den zweiten Antrieb ausgibt. Erfindungsgemäß überführt der zweite Antrieb über ein Kraftübertragungselement die Kupplung von einem trennenden Zustand in den kraftübertragenden Zustand.Embodiments of the invention provide a lock for a vehicle door which has at least one opening mechanism which can be coupled to a first drive, a clutch which can be mechanically transferred from at least one manual actuating element into a force-transmitting state and, in the force-transmitting state, the at least one opening mechanism with the first drive (20) couples, a second drive coupled to a securing element, wherein the securing element in a first stationary position blocks a manual actuation via an inner actuating element, and an evaluation and control unit which outputs corresponding control signals to the first drive and the second drive. According to the invention, the second drive transfers the coupling from a separating state into the force-transmitting state via a force transmission element.
Üblicherweise umfassen Fahrzeugschlösser mindestens eine als Drehfalle ausgeführte Schließvorrichtung. Die Drehfalle umschließt einen Bolzen, wodurch ein verriegelter Zustand realisiert werden kann.Usually, vehicle locks comprise at least one locking device designed as a catch. The rotary latch encloses a bolt, whereby a locked state can be realized.
Unter dem verriegelten Zustand wird im Folgenden der Zustand verstanden, in welchem eine Betätigung eines Außenbetätigungselements unwirksam ist. Das heißt, dass die Fahrzeugtür nicht durch Betätigung des Außenbetätigungselements entriegelt oder geöffnet werden kann.The locked state is understood below to be the state in which an actuation of an external actuating element is ineffective. That is, the vehicle door can not be unlocked or opened by operation of the outside operating member.
Der verriegelte Zustand kann zudem durch einen gesicherten und einen entsicherten Zustand unterschieden werden. Im gesicherten verriegelten Zustand ist neben dem Außenbetätigungselement auch das Innenbetätigungselement unwirksam. Dieser Zustand wird erzielt, indem sich das Sicherungselement in der ersten stationären Stellung befindet, in welcher eine Übertragung der manuellen Betätigung des Innenbetätigungselements auf die Schließvorrichtung unterbunden ist. Dadurch kann die Fahrzeugtür nicht durch Betätigung des Innenbetätigungselements entriegelt oder geöffnet werden. Im ungesicherten verriegelten Zustand kann eine Übertragung der manuellen Betätigung des Innenbetätigungselements auf die Schließvorrichtung ausgeführt werden und die Fahrzeugtür über das Innenbetätigungselement geöffnet werden. Durch die Betätigung des Innenbetätigungselements wird das Schloss zumindest entriegelt, so dass die Fahrzeugtür geöffnet werden kann.The locked state can also be distinguished by a secure and an unlocked state. In the secured locked state, the inner actuating element is ineffective in addition to the external actuating element. This state is achieved by the securing element being in the first stationary position, in which a transmission of the manual actuation of the inner actuating element to the closing device is prevented. Thereby, the vehicle door can not be unlocked or opened by operation of the inner operating member. In the unsecured locked state, a transmission of the manual operation of the inner actuator to the locking device can be carried out and the vehicle door can be opened via the inner actuator. By the operation of the inner actuating element, the lock is at least unlocked, so that the vehicle door can be opened.
Zum Entriegeln gibt die Drehfalle üblicherweise den umschlossenen Bolzen frei. Zu diesem Zweck kann die Drehfalle gedreht werden. Die Wirkverbindung zwischen dem Innenbetätigungselement und der Drehfalle kann direkt mechanisch, beispielsweise über Hebelverbindungen usw., oder indirekt durch elektrische bzw. elektronische Signale und einen korrespondierenden Antrieb hergestellt werden. Die elektrischen bzw. elektronischen Signale können beispielsweise durch Auswerten von Sensoren und Endschaltern erzeugt werden, welche die Stellung des manuellen Betätigungselements erfassen.To unlock the catch usually releases the enclosed bolt. For this purpose, the catch can be rotated. The operative connection between the inner actuating element and the rotary latch can be made directly mechanically, for example via lever connections, etc., or indirectly by electrical or electronic signals and a corresponding drive. The electrical or electronic signals can be generated for example by evaluating sensors and limit switches, which detect the position of the manual actuating element.
Der verriegelte Zustand kann beispielsweise auch über eine Fernbedienung aufgehoben werden, wobei der erste Antrieb über ein entsprechendes drahtlos übertragenes Signal aktiviert wird und die Drehfalle antreibt. Die Fernbedienung erzeugt das drahtlose übertragene Signal beispielsweise in Reaktion auf eine manuelle Betätigung eines Betätigungselements der Fernbedienung.The locked state can be canceled, for example, via a remote control, wherein the first drive is activated via a corresponding wirelessly transmitted signal and drives the catch. The remote control generates the wireless transmitted signal, for example, in response to a manual operation of an operating element of the remote control.
Unter einem geschlossen Zustand der Fahrzeugtür wird, im Folgenden der Zustand verstanden, in welchem die Fahrzeugtür geschlossen aber nicht verriegelt ist. Das bedeutet, dass die Fahrzeugtür während der Fahrt nicht aufspringt aber bei Betätigung der Betätigungselemente geöffnet werden kann. Alternativ kann das Fahrzeug auch eine Kindersicherung aufweisen, welche im gesicherten Zustand eine manuelle Betätigung des korrespondierenden Innenbetätigungselements unwirksam macht.Under a closed state of the vehicle door, hereinafter the state understood in which the vehicle door is closed but not locked. This means that the vehicle door does not spring open while driving but can be opened when the actuators are actuated. Alternatively, the vehicle may also have a child safety device, which makes a manual operation of the corresponding inner actuating element ineffective in the locked state.
Im offenen Zustand des Schlosses kann die Fahrzeugtür aufgeschwenkt werden. Um den Öffnungsvorgang zu unterschützen, kann die Drehfalle die Fahrzeugtür vom Fahrzeugrahmen wegstoßen, wodurch die Fahrzeugtür einen Spalt geöffnet wird. Bisher kann der Öffnungsvorgang nur dann erleichtert werden, wenn über die manuellen Betätigungselemente die Kupplung mechanisch eingelegt wird. Dadurch wird ermöglicht, dass der erste Antrieb die Drehfalle weiter drehen kann, so dass die Drehfalle die Fahrzeugtür freigibt und die Fahrzeugtür geöffnet bzw. aufgestoßen wird. Bei Betätigung einer Fernbedienung, wird die Kupplung nicht eingelegt und die Fahrzeugtür wird lediglich entriegelt aber nicht geöffnet. Bei Ausführungsformen des erfindungsgemäßen Schlosses für eine Fahrzeugtür kann die Kupplung in vorteilhafter Weise basierend auf einem elektrischen Öffnungssignal über den zweiten Antrieb eingelegt werden, wodurch eine automatisierte Öffnung der Fahrzeugtür über den ersten Antrieb ermöglicht wird. Zudem können Ausführungsformen des erfindungsgemäßen Schlosses für eine Fahrzeugtür in vorteilhafter Weise verhindert, dass die elektrische Öffnung der Fahrzeugtür in einer Unfallsituation erfolgt.In the open state of the lock, the vehicle door can be swung open. To undercut the opening process, the catch may push the vehicle door away from the vehicle frame, thereby opening the vehicle door a gap. So far, the opening process can only be facilitated if the clutch is mechanically engaged via the manual actuation elements. This allows the first drive to continue to rotate the catch such that the catch releases the vehicle door and the vehicle door is opened or pushed open. When a remote control is operated, the clutch is not engaged and the vehicle door is only unlocked but not opened. In embodiments of the lock according to the invention for a vehicle door, the clutch can be advantageously inserted based on an electrical opening signal via the second drive, whereby an automated opening of the vehicle door is made possible via the first drive. In addition, embodiments of the lock according to the invention for a vehicle door can be advantageously prevented that the electric opening of the vehicle door takes place in an accident situation.
Unter einer eingelegten Kupplung wird eine Kupplung im kraftübertragenden Zustand verstanden. Unter einer ausgelegten Kupplung wird eine Kupplung im trennenden Zustand verstanden.An engaged clutch is understood to mean a clutch in the force-transmitting state. A designed clutch is understood to mean a clutch in the separating state.
Die Betätigungselemente können mechanisch direkt über Hebelverbindungen und/oder indirekt über erzeugte elektrische bzw. elektronische Signale und den ersten Antrieb mit der Schließvorrichtung gekoppelt werden. Die Öffnungsvorrichtung und die Verriegelungsvorrichtung sind Elemente der Schließvorrichtung.The actuating elements can be coupled mechanically directly via lever connections and / or indirectly via generated electrical or electronic signals and the first drive with the closing device. The opening device and the locking device are elements of the locking device.
Die Auswerte- und Steuereinheit ist mit Schaltern und Sensoren verbunden, über welche die Stellung des Sicherheitselements und/oder der Kupplung und/oder der Schließvorrichtung und/oder der verschiedenen manuellen Betätigungselemente ermittelbar ist. In Abhängigkeit von der Stellung des Sicherheitselements und/oder der Kupplung und/oder der Schließvorrichtung und/oder der verschiedenen manuellen Betätigungselemente bestimmt die Auswerte- und Steuereinheit den aktuellen Zustand des Fahrzeugschlosses. Hierbei werden Öffnungssignale, welche von den mit den Betätigungselementen gekoppelten Schaltern ausgegeben werden, nur unter vorgegebenen Bedingungen an den ersten Antrieb weitergeleitet. So werden die von den Innenbetätigungselementen bewirkten Öffnungssignale nur im ungesicherten aber nicht im gesicherten Zustand an den ersten Antrieb weitergeleitet.The evaluation and control unit is connected to switches and sensors, via which the position of the security element and / or the clutch and / or the closing device and / or the various manual actuating elements can be determined. Depending on the position of the security element and / or the clutch and / or the closing device and / or the various manual actuating elements, the evaluation and control unit determines the current state of the vehicle lock. In this case, opening signals which are output by the switches coupled to the actuators are forwarded to the first drive only under predetermined conditions. Thus, the opening signals caused by the internal operating elements are forwarded to the first drive only in the unsecured but not in the secured state.
In vorteilhafter Ausgestaltung des erfindungsgemäßen Schlosses kann der zweite Antrieb das Sicherungselement zwischen der ersten stationären Stellung und mindestens einer weiteren stationären Stellung bewegen, wobei das Sicherungselement in einer zweiten stationären Stellung eine manuelle Betätigung über das Innenbetätigungselement zulässt. In vorteilhafter Weise weist das die Fahrzeugtür in der ersten stationären Stellung des Sicherungselements den geschlossenen, verriegelten und gesicherten Zustand auf. Des Weiteren weist die Fahrzeugtür in der zweiten stationären Stellung des Sicherungselements den geschlossenen, verriegelten und entsicherten Zustand auf. Der zweite Antrieb kann in vorteilhafter Weise als Linearantrieb ausgeführt werden.In an advantageous embodiment of the lock according to the invention, the second drive can move the securing element between the first stationary position and at least one further stationary position, wherein the securing element permits manual actuation via the inner actuating element in a second stationary position. This advantageously has the vehicle door in the first stationary position of the securing element to the closed, locked and secured state. Furthermore, in the second stationary position of the securing element, the vehicle door has the closed, locked and unlocked state. The second drive can be carried out in an advantageous manner as a linear drive.
In weiterer vorteilhafter Ausgestaltung des erfindungsgemäßen Schlosses kann das Sicherungselement mit dem Kraftübertragungselement gekoppelt werden, wobei das Kraftübertragungselement die Kupplung über das Sicherungselement mit dem zweiten Antrieb koppelt. In vorteilhafter Weise kann der zweite Antrieb sowohl das Sicherungselement und über das Kraftübertragungselement auch die Kupplung in die vorgegebenen Stellungen überführen.In a further advantageous embodiment of the lock according to the invention, the securing element can be coupled to the force transmission element, wherein the force transmission element couples the coupling via the securing element with the second drive. Advantageously, the second drive can convert both the securing element and the power transmission element and the clutch in the predetermined positions.
In weiterer vorteilhafter Ausgestaltung des erfindungsgemäßen Schlosses kann das Kraftübertragungselement die Kupplung in der zweiten stationären Stellung des Sicherungselements in den kraftübertragenden Zustand und in der ersten stationären Stellung des Sicherheitselements in den trennenden Zustand überführen. In vorteilhafter Weise ist die Öffnungsvorrichtung über die Kupplung mit dem ersten Antrieb gekoppelt, so dass auch eine Betätigung über das Innenbetätigungselement möglich ist.In a further advantageous embodiment of the lock according to the invention, the force transmission element can convert the coupling in the second stationary position of the securing element in the force-transmitting state and in the first stationary position of the security element in the separating state. Advantageously, the opening device is coupled via the coupling with the first drive, so that an actuation via the internal actuating element is possible.
In weiterer vorteilhafter Ausgestaltung des erfindungsgemäßen Schlosses kann die Auswerte- und Steuereinheit nach Empfang eines Öffnungssignals ein erstes Steuersignal an den zweiten Antrieb ausgeben, welcher die Kupplung über das Sicherungselement und das Kraftübertragungselement in den kraftübertragenden Zustand überführt. Das Öffnungssignal ist vorzugsweise ein elektrisches Signal, welches durch eine manuelle Betätigung einer Fernbedienung und/oder eines Betätigungselements am Fahrzeug erzeugt werden kann. Die Auswerte- und Steuereinheit kann nach der Überführung der Kupplung in den kraftübertragenden Zustand ein zweites Steuersignal an den ersten Antrieb ausgeben, welcher mindestens die Öffnungsmechanik antreibt. Zudem kann die Auswerte- und Steuereinheit nach Empfang eines Crashsignals ein drittes Steuersignal an den zweiten Antrieb ausgeben. In Reaktion auf das dritte Steuersignal überführt der zweite Antrieb die Kupplung über das Sicherungselement und das Kraftübertragungselement in den trennenden Zustand. Nach der Überführung der Kupplung in den trennenden Zustand kann die Auswerte- und Steuereinheit ein viertes Steuersignal an den ersten Antrieb ausgeben, welcher mindestens eine Entriegelungsmechanik antreibt. Nach der Entriegelung kann die Auswerte- und Steuereinheit das erste Steuersignal an den zweiten Antrieb ausgeben, welcher die Kupplung in den kraftübertragenden Zustand überführt. In vorteilhafter Weise wird in einer Unfallsituation die Kupplung erst ausgelegt, um ein ungewolltes Öffnen der Fahrzeugtür zu unterbinden. Für den Fall, dass die Kupplung bereits ausgelegt ist, passiert nichts weiter. Das anschließende Entriegeln des Schlosses und das Einlegen der Kupplung ermöglichen in vorteilhafter Weise ein Öffnen der Fahrzeugtür durch die Rettungskräfte, um nach einem Unfall Insassen aus dem Fahrzeug zu bergen.In a further advantageous embodiment of the lock according to the invention, the evaluation and control unit, after receiving an opening signal output a first control signal to the second drive, which transfers the coupling via the securing element and the force transmission element in the force-transmitting state. The opening signal is preferably an electrical signal which can be generated by a manual operation of a remote control and / or an actuating element on the vehicle. The evaluation and control unit can output after the transfer of the clutch in the power transmitting state, a second control signal to the first drive, which drives at least the opening mechanism. In addition, the evaluation and control unit can output a third control signal to the second drive after receiving a crash signal. In response to the third control signal, the second drive transfers the clutch via the securing element and the force transmission element in the separating state. After the transfer of the clutch into the separating state, the evaluation and control unit can output a fourth control signal to the first drive, which drives at least one unlocking mechanism. After unlocking, the evaluation and control unit can output the first control signal to the second drive, which converts the clutch into the force-transmitting state. Advantageously, in an accident situation, the clutch is first designed to prevent unwanted opening of the vehicle door. In the event that the clutch is already designed, nothing happens. The subsequent unlocking of the lock and the insertion of the coupling advantageously allow the vehicle door to be opened by the rescue workers in order to retrieve passengers from the vehicle after an accident.
In einer alternativen vorteilhaften Ausgestaltung des erfindungsgemäßen Schlosses kann der zweite Antrieb das Sicherungselement in eine zusätzliche dritte Stellung überführen, in welcher das Kraftübertragungselement die Kupplung in den kraftübertragenden Zustand überführt. Zudem kann das Kraftübertragungselement die Kupplung in der zweiten stationären Stellung des Sicherungselements in einen freigegebenen Zustand überführen, in welchem die Kupplung über ein manuelles Betätigungselement in den kraftübertragenden Zustand überführbar ist. Des Weiteren kann das Kraftübertragungselement die Kupplung in der ersten stationären Stellung des Sicherheitselements in den trennenden Zustand überführen. In vorteilhafter Weise können durch drei Stellungen des Sicherungselements drei Zustände erzielt werden. In der ersten stationären Stellung ist das Innenbetätigungselement gesperrt und die Kupplung ist nicht eingelegt. In der zweiten stationären Stellung lässt das Sicherungselement eine manuelle Betätigung über das Innenbetätigungselement zu und die Kupplung ist nicht eingelegt. In der dritten Stellung des Sicherungselements ist die Kupplung eingelegt und die Öffnungsvorrichtung kann über den ersten Antrieb betätigt werden.In an alternative advantageous embodiment of the lock according to the invention, the second drive can convert the securing element into an additional third position, in which the force transmission element transfers the clutch into the force-transmitting state. In addition, the power transmission element, the clutch in the second stationary position of the securing element in a released state transfer, in which the clutch via a manual actuator in the power transmitting state can be transferred. Furthermore, the force transmission element can convert the coupling in the first stationary position of the security element in the separating state. Advantageously, three states can be achieved by three positions of the fuse element. In the first stationary position, the inner actuator is locked and the clutch is not engaged. In the second stationary position, the securing element permits manual actuation via the inner actuating element and the clutch is not engaged. In the third position of the securing element, the clutch is engaged and the opening device can be actuated via the first drive.
In weiterer vorteilhafter Ausgestaltung des erfindungsgemäßen Schlosses kann der zweite Antrieb das Sicherungselement gegen eine Federkraft eines Federelements von der zweiten stationären Stellung in die dritte Stellung überführen und das Federelement vorspannen. Bei abgeschaltetem zweitem Antrieb kann die Federkraft des vorgespannten Federelements das Sicherungselement von der dritten Stellung zurück in die zweite stationäre Stellung überführen. In vorteilhafter Weise wird das Sicherungselement zurück in die zweite stationäre Stellung überführt, wenn der zweite Antrieb nicht mehr bestromt wird. Dadurch gelangt die Kupplung in vorteilhafter Weise in den freigegebenen Zustand, so dass die Kupplung durch eine manuelle Betätigung eines Betätigungselements oder durch den zweiten Antrieb eingelegt werden kann. Vorzugsweise weist die Kupplung ein Langloch auf, durch welches die Kupplung manuell über das Außenbetätigungselement und/oder das Innenbetätigungselement oder durch den zweiten Antrieb eingelegt werden kann.In a further advantageous embodiment of the lock according to the invention, the second drive can convert the securing element against a spring force of a spring element from the second stationary position to the third position and bias the spring element. When switched off the second drive, the spring force of the prestressed spring element can transfer the securing element from the third position back to the second stationary position. Advantageously, the securing element is transferred back to the second stationary position when the second drive is no longer energized. As a result, the clutch passes in an advantageous manner in the released state, so that the coupling can be inserted by a manual operation of an actuating element or by the second drive. Preferably, the coupling has a slot through which the coupling can be manually inserted via the external actuating element and / or the inner actuating element or by the second drive.
In weiterer vorteilhafter Ausgestaltung des erfindungsgemäßen Schlosses kann die Auswerte- und Steuereinheit nach Empfang eines Öffnungssignals ein erstes Steuersignal an den zweiten Antrieb ausgeben, welcher die Kupplung über das Sicherungselement und das Kraftübertragungselement in den kraftübertragenden Zustand überführt. Nach der Überführung der Kupplung in den kraftübertragenden Zustand kann die Auswerte- und Steuereinheit ein zweites Steuersignal an den ersten Antrieb ausgeben, welcher mindestens die Öffnungsmechanik antreibt. Da durch das erste Steuersignal die Kupplung eingelegt wird, kann in vorteilhafter Weise mit dem zweiten Steuersignal die Fahrzeugtür geöffnet werden. Das Öffnungssignal ist vorzugsweise ein elektrisches Signal, welches durch eine manuelle Betätigung einer Fernbedienung und/oder eines Betätigungselements am Fahrzeug erzeugt werden kann. In vorteilhafter Weise kann die Fahrzeugtür über die Fernbedienung und/oder des Bedienelement nicht nur entriegelt sondern auch geöffnet werden.In a further advantageous embodiment of the lock according to the invention, the evaluation and control unit, after receiving an opening signal output a first control signal to the second drive, which transfers the coupling via the securing element and the force transmission element in the force-transmitting state. After the transfer of the clutch into the force-transmitting state, the evaluation and control unit can output a second control signal to the first drive, which drives at least the opening mechanism. Since the clutch is engaged by the first control signal, the vehicle door can be opened in an advantageous manner with the second control signal. The opening signal is preferably an electrical signal which can be generated by a manual operation of a remote control and / or an actuating element on the vehicle. Advantageously, the Not only unlock the vehicle door via the remote control and / or the operating element but also open it.
In weiterer vorteilhafter Ausgestaltung des erfindungsgemäßen Schlosses kann die Auswerte- und Steuereinheit nach Empfang eines Crashsignals ein fünftes Steuersignal an den zweiten Antrieb ausgeben, wobei der zweite Antrieb die Kupplung in Reaktion auf das fünfte Steuersignal über das Sicherungselement und das Kraftübertragungselement in den freigegebenen Zustand überführen kann, in welchem die Kupplung über ein manuelles Betätigungselement in den kraftübertragenden Zustand überführt werden kann. Nach der Überführung der Kupplung in den freigegeben Zustand kann die Auswerte- und Steuereinheit ein viertes Steuersignal an den ersten Antrieb ausgeben, welcher mindestens eine Entriegelungsmechanik antreibt. Das Entriegeln des Schlosses ermöglicht in vorteilhafter Weise ein Öffnen der Fahrzeugtür durch die Rettungskräfte, um nach einem Unfall Insassen aus dem Fahrzeug zu bergen.In a further advantageous embodiment of the lock according to the invention, the evaluation and control unit can output a fifth control signal to the second drive after receiving a crash signal, the second drive can convert the clutch in response to the fifth control signal via the fuse element and the power transmission element in the released state in which the clutch can be transferred via a manual actuator in the power transmitting state. After the transfer of the clutch in the released state, the evaluation and control unit can output a fourth control signal to the first drive, which drives at least one unlocking mechanism. Unlocking the lock advantageously allows the vehicle door to be opened by the rescue workers in order to retrieve passengers from the vehicle after an accident.
