Definitions

  • the invention relates to a locking device, in particular for a mobile vehicle element of a vehicle.
  • Closing devices in particular locks or locking mechanisms, are known from the prior art, which are used, for example, in motor vehicles for locking backrests, doors, hoods, tailgates, trunk lids or the like.
  • a locking mechanism formed from a pawl, a rotary latch and a locking element, in particular in the form of a locking bracket or locking bolt, is set in motion by means of a motor in order to move the pawl from a locked position to an unlocked position.
  • the rotary latch In the unlocked position of the pawl, the rotary latch is released in order to be able to open it from a closed position to an open position.
  • the rotary latch can be moved beyond a main latching position so that the pawl can fall into a latching recess of the rotary latch.
  • Conventional closing devices in particular with closing functions, have comparatively high sealing pressures. If the sealing pressure is high, a so-called opening bang occurs when the locking device is opened, which is caused, for example, by the fact that a tension, in particular pretension, is built up on the associated movable vehicle element during a closing process.
  • the tension is generated by a compressible sealing element, in particular a door sealing element, arranged on the movable vehicle element and/or on a vehicle opening.
  • a compressible sealing element in particular a door sealing element
  • the preload on the sealing element and thus on the movable vehicle element arises if the sealing element is compressed too much during the closing process.
  • a compression takes place, for example, in that during a closing process the rotary latch is moved beyond the main latching position in order to then strike against a latching lug of the pawl for locking the rotary latch on the pawl.
  • the rotary latch can also be prestressed in the opening direction. Due to a pretensioning of the rotary latch, for example, there is a latching engagement between the rotary latch and the blocking element with a corresponding pretensioning load.
  • the catch is supported during a closing process between the pre-locked position and the main lock and end position, the sealing pressure already building up when the rotary latch is moved from the pre-locked position to the main lock position.
  • the invention is based on the object of specifying an improved locking device which, for example during an opening process, prevents an acoustically perceptible, unpleasant and undesirable opening noise, in particular a so-called opening bang.
  • the locking device in particular for a movable vehicle element of a motor vehicle, comprises at least one rotary latch, a locking element and an associated locking mechanism.
  • the blocking mechanism comprises at least one blocking element and a movable actuating element for the closing coupling of the rotary latch and the closing element, the movable actuating element being set up to move the rotary latch into a closed position going beyond at least one latching position and to lock it in this closed position. In the closed position, the rotary latch and the blocking element are not engaged. Furthermore, the rotary latch and the closing element are coupled to one another in a fully closing manner in the closed position.
  • the actuating element is designed to fulfill two functions.
  • the actuating element is a so-called closing aid.
  • the actuating element is designed as a closing pawl or closing lever.
  • the actuating element has the additional properties of a blocking element, for example a pawl or a blocking lever.
  • One function is to move the rotary latch into the closed position, in particular to adjust it, for example to pivot or rotate it.
  • Another function is to lock and/or block the rotary latch in the closed position. For example, a movement of the rotary latch back in the direction of the open position is blocked by the actuating element.
  • the rotary latch is coupled to the actuating element in the closed position in such a way that the rotary latch rests at least in sections on the actuating element and is thereby held by the latter, in particular in a locking and/or blocking manner.
  • the actuating element is fixed in position in the closed position, so that further rotary movement of the catch in the direction of the open position is blocked.
  • the actuating element is set up to keep the rotary latch in the closed position self-locking.
  • the actuating element presses against the catch in the closed position.
  • the rotary latch is held, for example, in a clamped manner on the actuating element.
  • the locking device is designed to at least reduce or even prevent an opening noise, in particular an opening bang, during an opening process of the movable vehicle element.
  • the locking device is also set up to keep a sealing pressure on the movable vehicle element and/or in the locking device in the closed position as low as possible until the next opening process.
  • the rotary latch In order to eliminate this opening bang, during the closing process the rotary latch is first moved into the at least one detent position and, after the detent position has been reached, into a defined overtravel. The rotary latch is then locked in an overtravel position corresponding to the overtravel by means of the actuating element.
  • This sequence enables a comparatively slow and delayed compression of the sealing element.
  • the locking device is additionally set in such a way that a sealing pressure is only applied when the rotary latch moves out of the latched position, for example a so-called main latched position. This means that at least the locking device is essentially stress-free in the latched position, for example in the main latched position. While the vehicle is being driven, the rotary latch remains in the arrested, closed position.
  • the rotary latch is reversed in a controlled manner by means of the actuating element.
  • the actuating element is set up to move the rotary latch from the closed position back into the at least one locking position, for example into the main locking position move essentially defined.
  • the rotary latch can then be decoupled from the blocking element, in particular it can be disengaged.
  • the blocking element is set up to release the rotary latch from the latched position, for example the main latched position, into the open position. In the open position of the locking device, in which the rotary latch and the locking element are disengaged, the actuating element and the rotary latch are also disengaged.
  • the blocking element can be unlocked at the same time as the reversing process of the rotary latch. As a result, there is no sudden release of a sealing force at any time during the opening process and the opening bang is thus prevented.
  • the blocking element is set up, for example, to release the rotary latch directly from the closed position when an opening process is initiated.
  • the blocking element is designed to be pivotable, for example, about an axis of rotation.
  • the rotary latch does not have to be moved back into a latched position in order to then be released into the open position.
  • the blocking element is pivoted in the direction away from the rotary latch before the rotary latch can reach the detent position provided for the closing process.
  • a locking device in particular in the form of a lock, which is designed with a comparatively reduced number of parts, reduced weight and reduced costs.
  • the locking device is designed to be easy to assemble.
  • the locking device according to the invention requires comparatively little space and offers a simple solution for eliminating opening noises. A vehicle that is to be manufactured or has already been manufactured and/or used can easily be upgraded with such a locking device.
  • the locking device includes closing kinematics or closing mechanisms.
  • the locking device is a lock, for example.
  • the lock includes, for example, the at least one rotary latch and the locking mechanism, which engage in one another in a latching manner, for example, and the locking mechanism blocks opening of the rotary latch that has fallen into a locking element, for example a locking bracket or locking bolt.
  • the lock includes a manual or motorized drive mechanism for opening the locking mechanism and for decoupling the rotary latch from the locking element.
  • the closing element is fixed to the vehicle, for example.
  • the closing element is arranged in a vehicle opening, for example a vehicle door opening, tailgate opening or hood opening.
  • a locking mechanism consisting of a rotary latch and a locking mechanism is arranged, for example, on the movable vehicle element.
  • the movable vehicle element can be adjusted completely automatically and by motor from the open position to the locked position and then to the closed position.
  • the movable vehicle element can also be partially moved manually into the latched position, for example by slamming the movable vehicle element.
  • the closing kinematics or closing mechanism can then be activated and intervene in order to support an adjustment of the rotary latch from the latched position to the closed position and thus to the driving position.
  • the actuating element is designed to carry out this supporting adjustment and the catch in the closed and
  • the actuating element locks the rotary latch in the closed position by means of a latching engagement, for example a frictional engagement and/or force-fitting engagement.
  • the actuating element blocks the rotary latch in the closed position by fixing the actuating element in a locking position, in which a path of movement of the rotary latch in the direction of the open position is blocked.
  • the movable actuating element can be driven by a motor.
  • the actuating element can be actuated, for example, by means of an actuation initiated via a microswitch.
  • electronic devices that are already present in the vehicle can be used to control the actuating element.
  • the axes of rotation of the blocking element, the rotary latch and the actuating element are in particular offset from one another.
  • the actuating element has at least one actuating contour directed in the direction of the rotary latch for initiating a movement of the rotary latch from the at least one locking position into the closed position.
  • the actuating element has at least one locking contour directed in the direction of the rotary latch for locking the rotary latch in the closed position until an opening process occurs.

  • the actuating element is designed to be pivotable about an axis of rotation between the open position and the closed position.
  • the rotary latch comprises at least one locking element which corresponds to a counter-locking element of the blocking element. Furthermore, the rotary latch comprises at least one stop element which is arranged on a side opposite the latching element and which can be actuated by the actuating element in order to adjust the rotary latch from the at least one latched position into the closed position. For example, the stop element comes into contact with the actuating element as soon as the actuating element is activated to move, in particular to adjust, the rotary latch from the at least one locking position, for example the main locking position, into the closed position. In the closed position, the rotary latch is kept locked and/or supported on the actuating element.

  • the system of the end stop 7.9 on the counter-locking element 8.2 is detected by the control unit as a signal and activation, in particular rotation, of the blocking element 8 is stopped.
  • the locking device 1 is set in such a way that the sealing pressure is only applied after the main detent position P2.1, in particular a so-called main detent, has been reached. That is, in the actual main latching position P2.1, the locking device 1, ie the entire system, is voltage-free. Counter-pressure exists only in the closed position P1 having the overtravel, in particular a driving position, of the rotary latch 7 .
  • the rotary latch 7 can be guided in a defined manner by means of the locking mechanism (Sm), in particular a so-called closing mechanism, during its actual reversing from the closed position P1 into the main locking position P2.1. Only then can the locking element 8 be unlocked. This process can also take place at the same time as the reversing starts. As a result, there is no sudden release of a sealing force at any time during the opening process O1, O2, and an opening bang is thus prevented.

  • the blocking element 8 is pivoted outwards about the axis of rotation Da1, ie in the direction away from the rotary latch 7. Further movement of the rotary latch 7 is now released and the rotary latch 7 pivots, for example spring-loaded, into the open position P3.
  • FIG 5 shows schematically a further opening process O2 of the closing device 1, which is moved from a closed position P1 directly into an open position P3.
  • the actuating element 9 is moved from the locking position VP in the direction of the unlocking position EP, for example adjusted by a motor.
  • the blocking element 8 is pivoted outwards about the axis of rotation Da1, ie in the direction away from the rotary latch 7, without the rotary latch 7, as in a closing process, having a latching position P2, for example the main latching position P2.1 and/or the pre-latching position P2.2. takes.
