Description

The invention relates to a coupling device for creating an operative connection between an actuating unit for actuating an opening mechanism for opening a closure part for a vehicle, a closure part, in particular in the form of a door or a hatch, for a vehicle, and a method for actuating an opening mechanism for opening the closure part .

Systems for opening vehicle doors are known from the prior art. Door handles protruding from the door panel are usually used, which a user can grasp to gain access to the interior of the vehicle. However, by protruding such door handles, the door handles affect the exterior appearance of the vehicle. Furthermore, the door handles form a wind resistance when driving, so that especially at high speeds of the vehicle, wind noise resulting from this can be perceptible inside the vehicle.

Due to the increased use of electrical opening mechanisms, the z. B. an electrical unlocking and / or opening of the door depending on an authentication signal can trigger an ID transmitter of a user, door handles as such are no longer absolutely necessary in many cases. However, the use of a handleless door has hitherto often been prevented by the fact that mechanical opening of the vehicle door is still desirable in certain situations in which the electric opening mechanism is not functioning properly. Such situations can be caused, for example, by an accident or an empty vehicle battery. At the same time, however, it should be ensured that unauthorized access to the vehicle is normally not possible.

It is an object of the present invention to at least partially eliminate the above disadvantages known from the prior art. In particular, it is an object of the present invention to increase security and in particular to create a mechanical opening option for a preferably handle-free closure part for a vehicle, in which unauthorized access to the vehicle can be prevented.

The above object is achieved by a coupling device having the features of the independent device claim, a closure part having the features of the further independent device claim, and a method having the features of the independent method claim. Further features and details of the invention result from the respective dependent claims, the description and the drawings. Features and details that are described in connection with the coupling device according to the invention naturally also apply in connection with the closure part according to the invention and/or the method according to the invention and vice versa, so that the disclosure of the individual aspects of the invention is or are always referred to alternately can.

According to a first aspect of the invention, a coupling device for creating a, in particular mechanical, operative connection between an actuating unit for Actuation of an opening mechanism for opening a closure part of a vehicle and the opening mechanism provided. The coupling device has a coupling unit, which is in a coupling state, in which the operative connection between the actuating unit and the opening mechanism, in particular for transmitting an actuating force from the actuating unit to the opening mechanism, is established, and in a decoupling state, in which the operative connection between the actuating unit and the opening mechanism is released, can be brought.

The (electromechanical) opening mechanism preferably comprises a bolt, a lock and/or a drive for opening and/or closing the closure part. The opening mechanism is preferably an electrical opening mechanism, by means of which the closure part is electrically, i. H. e.g. B. via an electric motor can be opened. The opening of the closure part can advantageously include an unlocking and/or an at least partial pivoting open of the closure part. The closure part can preferably be a door, a flap or the like of the vehicle. For the purposes of the present invention, the vehicle can be understood to mean, for example, a motor vehicle, preferably in the form of an electric vehicle.

An actuation action can preferably be performed by a user on the actuation unit, as a result of which the opening mechanism can be actuated when the coupling unit is in the coupling state. For example, the actuation unit can have an actuation element on which the user can perform a pushing movement or a pulling movement in order to carry out the actuation action. The actuation action can be passed on from the actuation unit to the opening mechanism by the coupling device in order to actuate the opening mechanism. Actuating the opening mechanism can preferably be understood as triggering a blocking unit which keeps the closure part closed or locks it before the opening mechanism is actuated. In particular, actuating the opening mechanism can also be referred to as activating the opening mechanism.

The coupling unit is preferably designed to mechanically connect two components in order to establish the operative connection between the actuating unit and the opening mechanism. In particular, the coupling device can be arranged between the actuating unit and the opening mechanism, for example in a covering of the closure part.

The coupling unit can preferably be designed such that a state change between the decoupling state and the coupling state can be carried out mechanically and/or electrically, preferably electromechanically. In this case, the coupling unit can be transferred from the decoupling state to the coupling state and/or vice versa. The fact that the operative connection between the actuating unit and the opening mechanism is released in the uncoupled state can be understood to mean that the operative connection between the actuating unit and the opening mechanism is canceled in the uncoupled state. For example, an actuation action by a user on the actuation unit in the coupling state can be forwarded through the coupling unit for actuation of the opening mechanism. In the decoupling state, the coupling unit can prevent or be able to prevent the actuation action from being transmitted to the opening mechanism.

Thus, by means of the coupling unit, an operative connection, in particular a mechanical one, can be achieved between the actuating unit and the opening mechanism, which is released in the decoupling state. As a result, unauthorized access to the vehicle via the actuating unit can be reliably prevented in the uncoupled state. Furthermore, depending on the situation, ie for example in the event of an accident or failure of an electrical function of the opening mechanism, the operative connection can be created by the coupling state in order to enable the closure part to be opened. In this way, for example, a vehicle occupant can be freed from the outside of the vehicle in the event of an accident. Furthermore, it is conceivable that a user gains access to the vehicle when an energy reserve of the vehicle battery is not sufficient to supply the electrical function of the opening mechanism. The operative connection can thus create a redundant opening option for the closure part, in particular for an emergency. The use of the coupling device is particularly advantageous for a handle-less locking part to enable an emergency opening of the locking part without arranging an additional lock or the like on the outside of the locking part.

Furthermore, in a coupling device according to the invention, it can advantageously be provided that a first connection element is provided for connection to the actuating unit and a second connection element is provided for connection to the opening mechanism, the first and second connection elements being able to be coupled or coupled by the coupling unit in the coupling state. In the decoupling state of the coupling unit, the first and second connecting element can be separated from one another by the coupling unit. The first and second connecting element can be coupled to one another directly or indirectly by the coupling unit, for example by fastening the first and second connecting element to one another. In particular, a mechanical movement as a result of an actuation action can be transmitted from the actuation unit to the opening mechanism by the first and second connecting element. The coupling of the first and second connecting element can be understood in particular as a mechanical active connection of the first and second connecting element, through which a force and/or movement of the first connecting element can be transmitted to the second connecting element. The first connecting element can be connectable or connected to the actuating unit and the second connecting element to the opening mechanism. The first and/or second connecting element can preferably be designed to be flexible. For example, the first and second connecting element can form a cable pull, by means of which the actuating unit can be connected to the opening mechanism in the coupled state. Furthermore, it is conceivable that the first and/or second connecting element comprise part of a cable pull. In particular, the first connecting element can be a first end of a first cable and the second connecting element can be a second end of a second cable of a cable pull, in particular a Bowden cable. Alternatively, it is conceivable that the connecting elements form adapter pieces that can be connected to one or more cable pulls.

Furthermore, it is conceivable in a coupling device according to the invention that the coupling unit is a coupling element for mechanically coupling the actuating unit and the opening mechanism, in particular wherein the coupling element is designed for positive and/or frictional connection with at least one of the connecting elements. The coupled state can be produced by the mechanical coupling of the actuating unit and the opening mechanism. In particular, it can be provided that at least one of the connecting elements or both connecting elements each have a recess into which the coupling element can be introduced to produce the coupling state. To produce the positive and/or frictional connection of the connecting elements, the coupling element can be movably mounted in order to be adjusted when the coupling unit is transferred from the decoupling state to the coupling state and/or vice versa. For example, the coupling element can be designed in the manner of a projection or a bolt and can engage in a recess of at least one of the connecting elements or both connecting elements. Provision can furthermore be made for the coupling element to have an undercut, in particular in the form of a dovetail, for the positive and/or frictional connection with at least one of the connecting elements. In particular, a coupling projection can have the undercut for engaging in the recess. Advantageously, the coupling element can be positively and/or frictionally connectable to one of the two connecting elements and can be fixedly or movably connected to the other of the two connecting elements.

Furthermore, it is conceivable in a coupling device according to the invention that the coupling unit has an actuator unit, by which the coupling element can be moved to transfer the coupling unit from the decoupling state to the coupling state and/or from the coupling state to the decoupling state. The actuator unit can include a drive motor, preferably in the form of an electric motor or electromagnet. Furthermore, it is conceivable that the actuator unit includes a gear for translating a drive movement from the drive motor to the coupling element. As a result, the drive motor can be dimensioned smaller, so that installation space and/or costs can be saved. In this case, the coupling element can be firmly connected to the actuator unit. For example, it is conceivable that an output element of the actuator unit is formed by the coupling element. Furthermore, it can be provided that the coupling element has a control section, in particular a magnetic or magnetizable one, and the actuator unit has a control section, in particular a magnetic one for controlling the coupling element for transferring the coupling unit from the decoupling state to the coupling state and/or from the coupling state to the decoupling state. For example, it is conceivable that the actuator unit is designed for magnetic activation of the coupling element. For this purpose, the actuator unit can comprise an electromagnet, for example, which can preferably be used to form the control element. The coupling element and/or an actuating element of the actuator unit can also have a magnetic or magnetizable area in order to achieve an interaction with the electromagnet.

It is also conceivable with a coupling device according to the invention that the connecting elements can be moved between an actuated position and an unactuated position in the coupling state, in particular with the actuated and/or the unactuated position being mechanically fixed by at least one stop element and/or recognizable by a position sensor. In particular, it can be provided that at least one of the connecting elements has a coupling area for coupling the connecting elements by the coupling element, in particular wherein the coupling element is released by the coupling area in an unactuated position and clamped by the coupling area in the actuated position. The stop element can be z. B. be a projection of a housing of the coupling device. In particular, the stop element can have a stop surface against which a counter stop surface of at least one of the connecting elements can rest in the actuated or unactuated position. By defining the actuated and/or unactuated position, a range of motion of the connecting elements can be defined in the coupled state, so that the opening mechanism can be actuated. At the same time, a user who actuates the actuation unit can be given haptic feedback that the actuated or unactuated position has been reached. The position sensor can advantageously comprise a switch and/or a proximity sensor. Through the position sensor, the actuated position z. B. be recognized and the coupling element are released and / or the mechanical actuation are stored electronically.

Furthermore, it is conceivable in a coupling device according to the invention that the coupling unit has a prestressing means for prestressing at least one of the Having fasteners in the unactuated position. The prestressing means can preferably be a spring, in particular a compression spring. This can ensure that the opening mechanism is activated only after the actuation unit has been actuated, ie the closure part does not open unintentionally. The biasing means can preferably be arranged in a housing of the coupling device and act between the housing and one of the connecting elements. The other connecting means can be indirectly operatively connected to the prestressing means via the coupling element. Furthermore, in the decoupling state, the prestressing means can ensure that at least one of the connecting elements, preferably both connecting means, is positioned in such a way that the coupling element can be moved with play. In particular, a frictional connection between the coupling element and the connecting elements can only arise when the connecting elements move, preferably against a prestressing force of the prestressing means. As a result, the coupling element can be positioned easily and thus reliably in order to establish the coupled state.

Furthermore, in a coupling device according to the invention, it can advantageously be provided that the actuator unit is guided and/or fastened to one of the connecting elements in order to be carried along during the movement of the connecting elements between the actuated and the unactuated position. In particular, one of the connecting elements can have a carrier section for accommodating the actuator unit. As a result, the coupling element can remain stationary relative to the actuator unit when the connecting elements are moved. As a result, it can be avoided, for example, that incorrect positioning occurs when positioning the connecting elements when moving between the actuated and the unactuated position and the coupling element can no longer be moved by the actuator unit.

Furthermore, in a coupling device according to the invention, it can advantageously be provided that the coupling unit has a housing in which the connecting elements are at least partially accommodated, in particular with the housing having two openings for passing through the connecting elements. The mechanical and/or electrical components of the coupling unit can be protected from environmental influences by the housing. Preferably, the housing be sealed against moisture. The housing can be made of plastic. Furthermore, the housing can have at least one attachment interface for attaching the housing to the closure part. The housing can preferably have exactly two openings, through which one of the connecting elements can be passed or can be passed.

Furthermore, in a coupling device according to the invention, it can advantageously be provided that the first and/or second connecting element has an actuating section for actuating the opening mechanism and a cladding section for at least partially enclosing the actuating section, with the cladding section being fastened to the housing, in particular in a stationary manner. The actuating section can preferably be provided for transmitting a force, as a result of which the opening mechanism can preferably be actuated. The cladding section is preferably designed to be pressure-resistant in order to guide the actuating section and to form a counter bearing for supporting tensile forces to be transmitted. To this end, it is particularly advantageous if the paneling section is attached to the housing. Preferably, the two openings for the passage of the connecting elements can each be sealed by a covering section of the respective connecting element that is passed through or is to be passed through. In particular, the first and/or second connecting element can be a Bowden cable. The actuating section can form a core of the Bowden cable and the covering section can form a cable sheath. As a result, a simple possibility can be provided for providing an operative connection between the actuating unit and the opening mechanism.

It is also conceivable within the scope of the invention for the coupling element to be arranged on the first or second connecting element, preferably in the non-actuated position, in particular in an articulated manner. As a result, an additional component can be saved and a simple mechanism for connecting the connecting elements can be created. In particular, the coupling element can have a coupling projection and a coupling body. The coupling projection can be designed for the positive and/or frictional connection of the connecting elements. The coupling body can be articulated on the first or second connecting element. For this purpose, the coupling body can be hinged be trained. In order to transfer the coupling unit into the coupling state, it can be provided that the coupling element is rotated about an axis of rotation on the first or second connection element. For example, it can be provided that the coupling element is arranged on the second connecting element and is rotated about the axis of rotation by the actuator unit when the coupling unit is transferred into the coupling state, so that the coupling element engages at least partially in the first connecting element. If the first connecting element is then subjected to a tensile load, a positive and/or frictional connection can arise between the first connecting element and the coupling element and in particular also between the first and second connecting element.

Furthermore, in a coupling device according to the invention it can advantageously be provided that the coupling element can be transferred into a blocking position in which a movement of the connecting elements into the actuated and/or the unactuated position is prevented by the coupling element. For example, by arranging the coupling element in an articulated manner on the first or second connecting element, the coupling element can be used to carry out a movement sequence in which the coupling element is transferred into the blocking position after the opening mechanism has been actuated, in particular for the first time, in which the coupling element can be actuated again with the actuator unit of the opening mechanism, preferably until it is released by the actuator unit. The coupling element and at least one of the connecting elements can each have a complementary area, through which a form fit can be achieved in the blocking position of the coupling element. As a result, movement of the coupling element in the blocking position can be prevented. The coupling element and/or the first or second connecting element preferably have complementary surfaces, by means of which a movement of the coupling element in the blocking position can be prevented. In particular, the actuator unit can represent an obstacle for the coupling element when the coupling element is in the blocking position. This can ensure that after the actuator unit has been actuated, the opening mechanism can only be actuated once. For example, if authentication is required to transfer the coupling unit from the decoupling state to the coupling state, this requirement can also be retained for subsequent actuation processes. does it if the mechanical actuation of the opening mechanism is an emergency actuation, this can also enable proof that the emergency actuation has been triggered.

Furthermore, in a coupling device according to the invention, it can advantageously be provided that a decoupling element is provided, through which the coupling element can be moved to transfer from the coupling state to the decoupling state, in particular wherein the decoupling element can be elastically prestressed when transferring from the coupling state to the decoupling state. The decoupling state can thus be present both in the blocked position and in the non-actuated position, for example. The decoupling element can include a spring, preferably in the form of a torsion spring. The decoupling element can be supported on the housing in order to transfer from the coupling state to the decoupling state. Furthermore, the movement sequence of the coupling element for moving the coupling element into the blocking position can be implemented mechanically by the decoupling element. In particular, the coupling element can be moved by the decoupling element independently of the actuator unit.

Furthermore, in a coupling device according to the invention, it can advantageously be provided that the actuator unit and the coupling element are coupled to one another by a link guide and/or that the coupling unit has a sliding section for the relative sliding movement of the coupling element to the actuator unit and/or to the decoupling element. In particular, the actuator unit and the coupling element can be permanently coupled to one another by the link guide. The actuator unit is preferably pivotably mounted on the housing. As a result, a lever mechanism can be created by which the coupling element can be reliably moved to transfer the coupling unit from the decoupling state to the coupling state. In particular, the coupling element and/or the first or second connecting element can strike the housing in the non-actuated position. The sliding section can be arranged in particular on the coupling element. For this purpose, the coupling element can have a guide, in particular a linear guide, in which the sliding section can be moved. The sliding section can preferably be controlled directly by the actuator unit and is activated relative to the actuator unit and/or to the coupling element when the connecting elements are moved from the unactuated position to the actuated position emotional. If the blocking position of the coupling element is then reached, in particular by the decoupling element, the coupling element can be blocked in the blocking position by the sliding section. For example, the sliding section can be supported on the actuator unit in the blocking position when the actuator unit is in an actuated state. The blocking of the coupling element by the sliding section can be canceled when the actuator unit is switched to an unactuated state.

It is also conceivable within the scope of the invention that a supply unit is provided, which is connected to the actuator unit for supplying electrical energy for operating the actuator unit, in particular with the supply unit having a receiving element for inductively receiving electrical energy for operating the actuator unit . In particular, the delivery unit and/or the receiving element can comprise an NFC interface. Furthermore, the supply unit can advantageously have an energy store, preferably in the form of a rechargeable battery and/or a capacitor, for example a gold cap. The receiving element may include an electrical coil to receive the electrical energy. The electrical energy can be receivable by the supply unit from an electrical device (preferably with an NFC interface), in particular a mobile terminal device, for example a cell phone. This can ensure that the electrical device is in the vicinity of the coupling unit when the electrical energy is provided. As a result, additional security can be created in that the coupling unit can only be transferred from the decoupling state to the coupling state by an explicit request from a user, in particular after an authentication process. In addition or as an alternative, it is conceivable for the supply unit to have a battery or the like, through which the electrical energy for the actuator unit can be supplied.

Furthermore, in a coupling device according to the invention, it can advantageously be provided that a control unit is provided for controlling the coupling unit for a state change between the coupling state and the decoupling state, in particular wherein the control unit has an authentication module for executing an authentication process for user authentication in order to To control coupling unit for the state change depending on the authentication process. The authentication module can be designed for wireless communication with a user's ID transmitter via a radio link, such as via NFC (Near Field Communication), Bluetooth, UWB (Ultra Wide Band). For this purpose, the authentication module can have at least one NFC interface, Bluetooth interface and/or UWB interface. NFC technology in particular offers the advantage that data is only transmitted over a short distance, preferably less than 25 cm, preferably less than 15 cm and particularly preferably less than 10 cm (tap-proof) and (contactless) energy transmission is also possible. In particular, it can be provided that the electrical energy for the supply unit can only be received by the supply unit as a function of the authentication process and/or can be provided for the operation of the actuator unit. Additionally or alternatively it can be provided that the supply unit is integrated into the control unit and/or the coupling unit. In particular, the provision unit can form at least part of the authentication module. Controlling the coupling unit by the control unit can preferably include controlling the actuator unit. The authentication process can include an exchange of identification signals. For example, if electrical energy is approached and/or electrical energy is inductively picked up by the supply unit, a query signal can be sent to a user's mobile terminal device. The user authentication can then be regarded as having taken place when an appropriately designed identification key of the mobile device is received in response to the identification signal.

Furthermore, in a coupling device according to the invention, it can advantageously be provided that the control unit is connected to the authentication module for the provision of the electrical energy by the provision unit depending on the authentication process with the provision unit. The coupling unit can thus be designed independently of a vehicle power supply. In particular, the authentication module and/or the provision unit can be designed to release the provision of energy for the operation of the coupling unit and/or to release the inductive consumption of energy by the provision unit depending on the authentication process. falls If the vehicle power supply is off, an emergency actuation of the opening mechanism can be carried out by the actuating unit, in particular in the first emergency state, while at the same time an authentication can be checked. This allows an additional electronic lock to be provided, which prevents unauthorized access.

According to a further aspect of the invention, a closure part, in particular in the form of a door or a flap, is provided for closing an opening of a vehicle. The closure part has an opening mechanism for opening the closure part, an actuating unit for actuating the opening mechanism and a coupling device, preferably according to the invention, for creating an operative connection between the actuating unit and the opening mechanism, in particular for transmitting an actuating force from the actuating unit to the opening mechanism. The coupling device comprises a coupling unit that can be brought into a coupling state, in which the operative connection between the actuating unit and the opening mechanism for actuating the opening mechanism by the actuating unit, and a decoupling state, in which the operative connection between the actuating unit and the opening mechanism is released .

A closure part according to the invention thus brings with it the same advantages as have already been described in detail with reference to a coupling device according to the invention. The opening mechanism can preferably be an electrical opening mechanism. Thus, the opening mechanism, the actuating unit and the coupling device can form a functional unit, for example, through which the closure part can be opened. Opening the closure part can be understood as unlocking, moving the closure part or the like. The closure part can be opened by the coupling device, in particular independently of an electrical function of the opening mechanism. Thus, in particular, an emergency opening of the closure part can be made possible by the coupling device.

It is preferably provided in a closure part according to the invention that the closure part and/or the actuating unit has a request interface which is designed as a user interface for a manual access request and/or as an electronic interface for an electrical access request. In particular, the actuating device can have at least two request interfaces, one of the request interfaces being designed as a user interface and a request interface as an electronics interface. The electrical access request can thus include an electrical signal, a radio signal. For example, the electronics interface can be formed by a control unit or an electrical connection to a central control unit of the vehicle. The user interface may be configured to receive the access request manually via a mechanical connection, such as a mechanical lock and/or gear. The user interface preferably includes a push-push mechanism, in particular on an actuating element of the actuating device. The push-push mechanism allows the actuating element to open as a result of a pressure actuation. The manual access request may include a mechanical movement. In particular, the actuating unit can be designed to be switched to the first emergency state via the user interface and/or to be switched to the second emergency state via the electronic interface.

It is also conceivable with a closure part according to the invention that the actuation unit can be brought into a normal state in which an actuation action on the actuation unit is prevented and into an emergency state in which the actuation action is enabled. It can be provided that in the normal state the closure part can only be opened by the electrical function of the opening mechanism. The emergency state can be produced, for example, by a control unit of the coupling device and/or of the vehicle when an emergency is detected. For example, an accident or a failure of the vehicle's power supply for the opening mechanism can be such an emergency. The actuation action can in particular be a manual actuation action in which a user actuates the actuation unit in order to open the closure part. It is preferably provided that the actuation action is transmitted from the actuating unit to the opening mechanism when the Coupling unit is in the pairing state. In particular, it can be provided that the transfer of the actuating unit from the normal state to the emergency state takes place independently of the transfer of the coupling unit from the coupling state to the decoupling state. For example, the actuating unit can be switched from the normal state to the emergency state as soon as an emergency is detected. However, the coupling unit can only be transferred from the decoupling state to the coupling state if user authentication was successful.

It is also conceivable within the scope of the invention for the actuating unit to have an actuating element, the actuating element being able to be brought into an actuating position in which the actuating element can be gripped by the user and into an operating position in which the actuating element is prevented from being gripped by the user is, in particular wherein the coupling unit is in operative connection with the actuating element. For example, the coupling unit can be connected to the actuating element by the first and/or second connecting element. The first and/or second connecting element can be attached directly or indirectly to the actuating element. If the actuating element is brought into the actuating position, force can be transmitted to the opening mechanism when the coupling unit is in the coupling state. The actuating element can be a flap, for example, which opens when the actuating unit is switched from the normal state to the emergency state. The actuating element can in particular also be referred to as a cover element, in particular behind which the coupling device is arranged inaccessible from an outside of the actuating device. The closure part can advantageously be a handle-less closure part in particular. As a result, the presence of a door handle in the normal state of the operating unit can be avoided. In particular, the actuating element can end flush, preferably flush, with an outer surface of the closure part, for example. As a result, for example, the wind resistance of the vehicle can be reduced. Furthermore, unauthorized access can be prevented in the normal state in that no mechanical actuation action can be carried out and the electrical opening mechanism can only be activated by authentication. Preferably, the actuating unit can a Have drive, through which the actuating element is automatically movable. For example, the drive can include a motor, in particular an electric motor and/or a spring, in order to move the actuating element.

It can preferably be provided in a closure part according to the invention that the actuating element is connected to an inside handle interface of the opening mechanism for actuation by an inside vehicle handle of the closing part or to an outside handle interface of the opening mechanism for actuation by an outside vehicle handle of the closing part. The connection of the actuating element to the inside handle interface and/or the outside handle interface can be interrupted by the coupling unit when the coupling unit is in the uncoupled state. The inside handle interface or the outside handle interface of the opening mechanism can be actuation interfaces through which a mechanical door handle can also be connected to the opening mechanism. Preferably, the outer handle interface can have an opening force of 300 N for performing the actuation action and the inner handle interface can have an opening force of 15 N for performing the actuation action. For example, if a rescue option is to be provided in an emergency, through which a first responder can open the closure part, a high opening force at the outside handle interface can contribute to increased safety in the normal state. On the other hand, a low opening force at the inside handle interface offers the advantage that a user still has a comfortable opening option for the closure part, for example if a vehicle power supply fails. The actuation of the actuation unit can in particular include recording a manual actuation action by a user. In this case, for example, an actuating element of the actuating unit can be moved and as a result an actuating force can be transmitted from the actuating unit to the opening mechanism via the coupling unit.

It is also conceivable within the scope of the invention for the actuating unit to have an emergency actuating element for actuating the opening mechanism for accident rescue, with the emergency actuating element being inaccessible from an outside of the actuating unit in the normal state and the actuating element being movable from the operating position beyond the actuating position, so that the emergency control element of is accessible from the outside of the operating unit. For example, it can be provided that the actuating element is opened further until a release position is reached. The fact that the emergency actuation element is arranged inaccessible from the outside in the normal state of the actuation unit can be understood to mean that the emergency actuation element cannot be grasped by a user in the normal state and/or cannot be moved to transmit the tensile force. For example, the emergency actuation element can be covered. As a result, the emergency actuation element can be arranged outside of the user's field of vision in the normal state, as a result of which an external appearance of the closure part is not impaired. For accident rescue, for example, the authentication process can be skipped by actuating the emergency actuating element in order to enable the closure part to be opened quickly. Provision is preferably made for the actuating element to be activated only when an accident is detected, e.g. B. by the control unit, on the operating position is also movable. It is conceivable for the emergency actuation element to be connected to an, in particular flexible, emergency connection element in order to transmit a pulling movement to the opening mechanism.

It is also conceivable with a closure part according to the invention that the emergency actuation element has a grip area, in particular in the form of a loop, which can be gripped by a user in order to move, in particular to pull, the emergency actuation element to actuate the opening mechanism. In particular, the grip area can include a free space into which the user can reach in order to move the emergency actuation element. In particular, the loop can be designed to be flexible. As a result, the emergency actuation element can only take up a small amount of space in the rest position and can still be easily gripped by a user. In particular, the grip area can be adjustable, ie in particular can be enlarged flexibly, for example by increasing the diameter of the loop. For this purpose, the loop can comprise a slidable knot or a slidable closure. The loop preferably comprises a coiled wire or a coiled rope. The loop can have an elastic covering, for example in the form of an elastomer, a foam or the like. As a result, the feel of the emergency actuation element can be improved in order to avoid uncomfortable strain on the user's hand. The grip area itself is also a particularly simple one Allows operation in which the user can apply a high tensile force. Preferably, the actuating unit can be designed in such a way that a tensile force of 300 N or more can be transmitted to the opening mechanism via the emergency actuating element.

It is preferably provided in a closure part according to the invention that the closure part and/or the actuating unit has a request interface for switching the actuating unit into the emergency state, which is designed as a user interface for a manual access request and/or as an electronic interface for an electrical access request. In particular, the actuating device can have at least two request interfaces, one of the request interfaces being designed as a user interface and a request interface as an electronics interface. The electrical access request can thus include an electrical signal, a radio signal. For example, the electronics interface can be formed by a control unit or an electrical connection to a central control unit of the vehicle. The user interface may be configured to receive the access request manually via a mechanical connection, such as a mechanical lock and/or gear. The user interface preferably includes a push-push mechanism, in particular on an actuating element of the actuating device. The push-push mechanism allows the actuating element to open as a result of a pressure actuation. The manual access request may include a mechanical movement. In particular, the actuating unit can be designed to be switched to the first emergency state via the user interface and/or to be switched to the second emergency state via the electronic interface.

According to a further aspect of the invention, a method for actuating an opening mechanism for opening a closure part of a vehicle, preferably according to the invention, by means of an actuating unit is provided. The procedure includes the following steps:

• Transferring a coupling unit of a coupling device, in particular a coupling device according to the invention, from a decoupling state in which an operative connection between the actuating unit and the opening mechanism is released, into a coupling state in which the operative connection between the actuating unit and the opening mechanism, in particular for actuating the opening mechanism by the actuating unit, is established,
• Transmission of an actuating force from the actuating unit to the opening mechanism in the coupling state of the coupling unit, in particular by the coupling unit, so that the opening mechanism is activated.

A method according to the invention thus entails the same advantages as have already been described in detail with reference to a closure part according to the invention and/or a coupling device according to the invention. The transfer of the coupling unit from the decoupling state to the coupling state can in particular take place automatically. For example, an actuator of the coupling unit can be controlled by a control unit of the actuating device and/or the closure part. The actuation force is transmitted in particular as a result of an actuation action by a user on the actuation unit. The actuating force can advantageously be a tensile force. Thus, a mechanical opening facility is provided through which unauthorized access, i. H. in particular unauthorized opening of the closure part is prevented in the uncoupled state of the coupling unit.

It is also conceivable within the scope of the invention that when the coupling unit is transferred from the decoupling state to the coupling state, a coupling element for mechanically coupling a first connecting element, which is designed to be connected to the actuating unit, to a second connecting element, which is designed to be connected to the opening mechanism , is moved. The coupling device can preferably comprise the first and the second connection element. In this case, the connecting elements can be mechanically connected by the coupling element, so that force can be transmitted when the actuating unit is actuated. In particular, a tensile force can thereby be transmitted as an actuating force from the actuating unit to the opening mechanism. As a result, it is not necessary, for example, to use a complicated lever mechanism to transmit the actuating force. Instead, a cable can be used, the can be guided in particular easily in the closure part from the actuating unit to the opening mechanism.

In a method according to the invention, it can preferably be provided that before the coupling unit is transferred from the decoupling state to the coupling state, electrical energy is inductively absorbed for the operation of an actuator unit for moving the coupling element. The electrical energy can be made available to the actuator unit by the inductive absorption of the electrical energy, so that the coupling element is moved automatically. For this purpose it can be provided that an authentication process is carried out beforehand, which is used for user authentication. In particular, the transfer of the coupling unit from the coupling state to the decoupling state or vice versa can be carried out as a function of the authentication process.

In the following description of some exemplary embodiments of the invention, identical reference symbols are used for the same technical features in different exemplary embodiments.

figure 1 shows a closure part 3 according to the invention for a vehicle 4 with an opening mechanism 200 for opening the closure part 3 and an actuating unit 100 for actuating the opening mechanism 200. figure 10 furthermore shows a method 300 according to the invention for actuating the opening mechanism 200 for opening the closure part 3, the actuating unit 100 in a schematic representation of the method steps to which reference is also made in the context of the following description.

A coupling device 1 is arranged between the opening mechanism 200 and the actuating unit 100 and can be used to produce an operative connection between the actuating unit 100 and the opening mechanism 200 . For this purpose, the coupling device 1 has a coupling unit 10 that can be brought into a decoupling state II, in which an operative connection is established between the actuating unit 100 and the opening mechanism 200 for actuating the opening mechanism 200 by the actuating unit 100 . To establish the operative connection between the actuating unit 100 and the opening mechanism 200, the coupling unit 10 can be transferred 302 from the decoupling state II to a coupling state I, with the operative connection being established in the coupling state I in order to transfer 303 an actuating force from the actuating unit 100 to the opening mechanism 200 to be able to perform. Decoupling state II is in figure 1 shown, the coupling state I in figure 2 . Unauthorized access to the vehicle 4 can thus be mechanically prevented in the decoupling state II by the opening mechanism 200 cannot be actuated by the actuating unit 100. In particular, only the actuating unit 100 can be arranged on the closure part 3 so that it is accessible from the outside. Thus, at least the opening mechanism 200 and the coupling device 1 can be arranged on an inside of the closure part 3 . It can be provided that the opening mechanism 200 can be actuated electrically. It is thus conceivable that the opening mechanism 200 can be controlled by a central control unit of the vehicle 4 as a function of a radio signal and thus the closure part 3 can be opened, for example, when a user's ID transmitter is detected. However, the coupling device 1 and the actuating unit 100 simultaneously enable a manual and/or mechanical access to the vehicle 4.

In the Figures 3 to 6 a coupling device 1 according to the invention is shown in a further exemplary embodiment. The coupling device 1 comprises a coupling unit 10, which is switched into a coupling state I, in which the operative connection between an actuating unit 100 and an opening mechanism 200 for actuating the opening mechanism 200 is established, and into a decoupling state II, in which the operative connection between the actuating unit 100 and the opening mechanism 200 is released, can be brought. figure 3 shows the coupling unit 10 in the decoupling state II. In order to establish the coupling state I, the coupling device 1 has a first connecting element 31 for connecting to the actuating unit 100 and a second connecting element 32 for connecting to the opening mechanism 200 . In decoupling state II, a movement of the first connecting element 31 is independent of a movement of the second connecting element 32. The connecting elements 31, 32 can be parts of a cable pull, through which an actuating force can be transmitted from the actuating unit 100 to the opening mechanism 200 when the first and second connecting element 31, 32 are coupled. In the decoupling state II, in particular, a power transmission from the first connecting element 31 to the second connecting element 32 is not possible. The first and second connecting element 31, 32 form a cable pull, in which the opening mechanism 200 can be actuated, when the coupling unit 10 is in coupling state I. To establish the coupling state I, which is figure 4 is shown, the coupling unit 10 has a coupling element 11 that is designed for the positive and/or frictional connection of the connecting elements 31, 32. The actuating unit 100 and the opening mechanism 200 can thus be mechanically coupled by the coupling element 11 such that an actuation of the actuating unit 100 leads to an actuation of the opening mechanism 200 . The coupling element 11 is connected to the second connecting element 32 in an articulated manner. However, it is also conceivable that the coupling element 11 is connected in an articulated manner to the first connecting element 31 .

The coupling device 1 also has a control unit 20 for controlling the coupling unit 10 for a state change between the coupling state I and the decoupling state II. If a user wants to actuate the opening mechanism 200 mechanically, for example due to a failed vehicle power supply, he can authenticate himself at the control unit, for example via a mobile terminal device. For this purpose, the control unit 20 has an authentication module 21 for carrying out an authentication process for user authentication. As a result, the coupling unit 10 can be controlled by the control unit 20 for the state change as a function of the authentication process. For this purpose, the coupling unit 10 also has an actuator unit 12, by which the coupling element 11 can be moved in order to transfer the coupling unit 10 from the decoupling state II to the coupling state I and/or vice versa. For this purpose, the actuator unit 12 can include an electric motor, for example, which can be activated as a function of the authentication process.

Furthermore, the coupling device 1 preferably has a supply unit 23 . The supply unit 23 can be part of the control unit 20, part of the coupling unit 10 and/or part of the actuator unit 12. In this case, the supply unit 23 is connected to the actuator unit 12 in order to supply electrical energy for operating the actuator unit 12 . The supply unit 23 can preferably also be designed to operate the control unit 20 . The supply unit 23 can advantageously include a receiving element 23.1 for the inductive receiving 301 of electrical energy for the operation of the actuator unit 12 and/or the control unit 20. The electrical energy is preferably consumed before the coupling unit 10 is transferred 302 to the coupling state I. The provision unit 23 can preferably be designed for NFC communication with a mobile device of a user. For example, the authentication process can take place at the same time as the inductive transmission of the electrical energy. Provision can furthermore be made for the authentication module 21 to be connected to the provision unit in order to enable the provision of energy, in particular as a function of the authentication process. This can ensure that the coupling element 11 is only moved by the actuator unit 12 if the user also has access authorization to the vehicle 4 or to open the closure part 3 . By controlling the actuator unit 12, the coupling element 11 is pivoted and/or rotated about an axis of rotation on the second connecting element 32, so that a coupling projection 11.1 engages in a recess 31.1 of the first connecting element 31. As a result, a form fit between the coupling element 11 and the first connecting element 31 is established. The actuator unit 12 preferably acts indirectly on the coupling element 11. In particular, a sliding section 19 can be arranged for sliding relative movement between the coupling element 11 and the actuator unit 12. As a result, the coupling unit 10 is now in the coupling state I, while the connecting elements 31, 32 are still in an unactuated position B. According to figure 4 the operating unit 100 has not yet been operated.

figure 5 shows the coupling unit 10 in the coupling state I, the connecting elements 31, 32 having been moved into an actuated position A until at least one of the connecting elements 31, 32 and/or the coupling element 11 strikes a stop element 13. In this case, the first connecting element 31 is subjected to a tensile load by actuating the actuating unit 100, so that the coupling element 11 and the connecting element 31 enter into a frictional connection and are moved along an actuating direction. As a result, the force is transmitted to the second connecting element 32 which can actuate the opening mechanism 200 . The first and second connecting element 31, 32 are part of a cable pull, the cable pull comprising at least two Bowden cable elements. Each of the Bowden cable elements has an actuating section 30.1 and a covering section 30.2. The actuating section 30.1 is part of the first and/or second connecting element 31, 32 and/or, in particular in one piece, with the first and/or second connecting element 31, 32 and can transmit a tensile force when actuating the actuating unit 100. The covering section 30.2 is designed to at least partially enclose the actuating section 30.2 and is in particular pressure-resistant. As a result, support can be provided on a housing 16 of the coupling device 1 . For this purpose, the covering section 30.2 is fastened to the housing 16, in particular in a stationary manner. At the same time, each cladding section 30.2 can be designed to seal an opening 16.1 of the housing 16, through which the actuating section 30.2 is passed. When transferring the connecting elements 31, 32 from the unactuated position B to the actuated position A, a prestressing means 14 is also prestressed, by means of which the connecting elements 31, 32 in the actuated position A are prestressed in the direction of the unactuated position B, i.e. opposite to the direction of actuation will. If the actuating action is completed and the actuating force decreases, e.g. B. by the user letting go of the actuating unit 100, the pretensioning unit 14 ensures that the first connecting element 31 is moved in the direction of the coupling element 11. As a result, the frictional connection between the connecting elements 31, 32 or between the coupling element 11 and the first connecting element 31 decreases, so that the coupling element 11 is again moved about the axis of rotation of the second connecting element 32 by a decoupling element 17 in the form of a torsion spring, but without being completely in to have returned to the idle position B.

As in figure 6 shown, the coupling element 11 rotates about the axis of rotation even before the sliding section 19 has reached a position under the actuator unit 12 and is thereby moved into a blocking position C, in which the coupling element 11 with the actuator unit 12 a renewed actuation of the opening mechanism, preferably 200 until released by the actuator unit 12, prevented. In particular, the coupling element 11 is clamped by the first connecting element 31 and the sliding section 19, so that a renewed actuation of the coupling element 11 is only possible when the actuator unit 12 has been transferred into an inactive state again by a driven element 12.1 of the actuator unit 12 being moved back. For this it may be necessary for the supply unit 23 to be recharged with energy and/or for the authentication process to be carried out again. Furthermore, coupling element 11 and the first connecting element 31 each have a complementary region 15 through which in the blocking position C of the coupling element 11 a form fit can be achieved. The complementary regions 15 each comprise a surface which interact with one another in the blocking position C in order to prevent the coupling element 11 from moving back. In particular, this can also subsequently provide evidence that a mechanical emergency actuation of the opening mechanism 200 has taken place.

figure 7 shows another embodiment of a coupling device 1 according to the invention, which essentially corresponds to the principle of FIG Figures 3 to 6 is equivalent to. In this case, however, the sliding section 19 is on an upper side of the coupling element 11, z. B. arranged in the form of a sliding coating. In this case, the coupling element 11 is not transferred into a blocking position C after an actuation action has taken place, so that repeated actuation of the opening mechanism 200 via the coupling device 1 is possible after authentication and release have taken place. It is also shown that a coupling projection 11.1 of the coupling element 11 has undercuts, in particular dovetail-shaped undercuts, so that the frictional connection between the first connecting element 31 and the coupling element 11 is positively improved by the undercut.

figure 8 shows a coupling device 1 according to the invention in a further embodiment. The actuator unit 12 is arranged in a housing 16 so that it can pivot. Furthermore, the actuator unit 12 and a coupling element 11 are coupled to one another by a link guide 18, so that the coupling element 11 and the actuator unit 12 form a lever mechanism. Furthermore, an articulated arrangement of the coupling element 11 on the second connecting element 32 is also provided, whereby a rotation of the coupling element 11 about an axis of rotation on the second connecting element 32 leads to a coupling projection 11.1 engaging in a recess 31.1 of a first connecting element 31, so that the actuating force can be transmitted is.

figure 9 shows a coupling device 1 with a coupling unit 10, which can be converted between a coupling state I and a decoupling state II. In contrast to the coupling device 1 of the first exemplary embodiment, however, two connecting elements 31, 32 are provided which connect the coupling device 1 to the actuating unit 100 and the opening mechanism 200 in order to form a To transmit actuating force between the actuating unit 100 and the opening mechanism 200, wherein a coupling element 11 engages in both connecting elements 31, 32 in order to connect the connecting elements 31, 32. In the exemplary embodiment shown here, an actuator unit 12 for actuating the coupling element 11 is also mounted on the second connecting element 32, so that the coupling element 11 remains stationary relative to the second connecting element 32, even if the connecting elements 31, 32 are adjusted between an actuated and an unactuated position A, B . However, it is also conceivable that the actuator unit 12 is arranged in a stationary manner and the coupling element 11 is pushed through both connecting elements 31, 32 if both connecting elements 31, 32 have cutouts 31.1. In particular, an output element 12.1 of the actuator unit 12 is formed by the coupling element 11. For example, the coupling element 11 can be designed magnetically and the actuator unit 12 can comprise an electromagnet for actuating the coupling element 11 . Furthermore, a position sensor 24 is shown, which is actuated by the second connecting element 32 and/or the actuator unit 12 when the actuated position A is reached. As a result, the actuated position A z. B. can be recognized and the coupling element 11 can be released and/or the mechanical actuation can be stored electronically.

In the Figures 11a to 11d shows the sequence of an emergency actuation via the coupling device 1 when a vehicle power supply has failed. How out Figure 11a As can be seen, a closure part 3 can be opened by a user. The closure part 3 is a handle-less closure part 3, in particular in the form of a handle-less vehicle door. An actuation unit 100 for mechanically opening the closure part 3 is in particular according to FIG Figure 11b convertible from a normal state N into an emergency state E, the emergency state E in Figure 11c is shown. For this purpose, a request interface 112 is provided for transferring the operating unit 100 into the emergency state E, which is designed as a user interface for a manual access request and/or as an electronic interface for an electrical access request. When transferring the operating unit 100 into the emergency state E, an operating element 110 of the operating unit 100 can be transferred into an operating position 110.1, in which the operating element 110 can be gripped by the user. For example, the electronics interface can be a proximity sensor and/or the user interface comprise a push-push mechanism for opening the actuating element 110. In the normal state N, the actuating element 110 is in an operating position 110.2, in which the actuating element 110 is prevented from being gripped by the user. Depending on the user's request, the actuating element 110 is thus brought into the actuating position 110.1. In the operating position 110.1, the operating element 110 is preferably pivotably mounted on an outer part of the closure part 3. Furthermore, it is conceivable that the actuating unit 100 has a drive 113, in particular in the form of an electric motor and/or a spring, by means of which the actuating element 110 can be moved. Furthermore, the actuating element 110 is preferably connected to a first connecting element 31 via an actuating section 30.1 of a cable pull. As long as the coupling device 1 is in the decoupling state II, a force from an actuation action 310 on the actuating element 110 is not transmitted to the opening mechanism 200 for opening the closure part 3 . Before the coupling unit 10 is transferred from the decoupling state II to a coupling state I, electrical energy is preferably received inductively by a supply unit 23 in the coupling device 1 . An authentication process for authenticating the user and/or the state change from the decoupling state II to the coupling state I of the coupling unit 10 can be carried out with the electrical energy. As in Figure 11d shown, it is then possible to perform the actuation action 310 on the actuation element 110 in order to transmit a force from the actuation unit 100 to the opening mechanism 200 via the coupling device 1 and thereby to open the closure part 3 . The actuating element 110 is connected to an inside handle interface 201 of the opening mechanism 200, which is designed for actuation by a vehicle inside handle of the closure part 3. As a result, a small force, in particular approximately 15 N, may be required when performing the actuation action 310 . However, it is also conceivable that the actuating element 110 can be connected to an outside handle interface 202 of the opening mechanism 200, which is designed for actuation by a vehicle outside handle of the closure part 3. As a result, an increased force, in particular of approximately 300 N, may be required when performing the actuation action 310 . Alternatively it is conceivable that the coupling unit 10 is integrated into the opening mechanism 200 .

In addition, actuating unit 100 has an emergency actuating element 40 for actuating opening mechanism 200 for accident rescue, with emergency actuating element 40 being inaccessible from an outside of actuating unit 100 in normal state N, and actuating element 110 being movable from operating position 110.2 beyond actuating position 110.1, see above that the emergency actuation element 40 is accessible from the outside of the actuation unit 100 . This allows the opening mechanism 200 to be operated quickly in the event of an accident. Provision can be made for the coupling unit 10 and/or a further coupling unit 10 to be connected between the emergency actuating element 40 and the opening mechanism 200 .

The above explanation of the embodiments describes the present invention exclusively in the context of examples. It goes without saying that individual features of the embodiments can be freely combined with one another, insofar as this makes technical sense, without departing from the scope of the present invention.
