Description

The The invention relates to a locking and unlocking device with the in the preamble of claim 1 mentioned features.

It is generally known that vehicle doors for motor vehicles in principle an outer wall and an inner wall are constructed and the outer wall, the body-side basic structure the vehicle door form. Based on this basic structure of the vehicle door a completion in which by the outer wall as well as by the Inner wall formed inside the most diverse components are positioned. These components include for example, next to the window panes with the associated actuating and guide elements as well as the vehicle locks also the door handles, mostly as outside handles preferably positioned in a recessed grip of the outer wall of the vehicle door be and arranged with a within the vehicle door closing device the vehicle lock usually with prior release of a lock cylinder in operative connection.

A typical arrangement of a door handle as an actuating device in a recessed grip as a mounting module is for example in the DE 44 33 182 C2 described.

There such an actuator as handle element in a recessed grip always present and visible is, even if it is not needed, there are a number of Disadvantages, this problem not only for door handles but for all actuator of lids, in particular tank lids; Hoods, especially in boot and engine hoods, or the like applies.

So is every actuator by their exposed position highly polluting, what understandably not wished is because the hands an operator when opening for example, a vehicle door or a tailgate can also pollute.

Farther should the actuator be so concealed that they talk as little as possible about the respective level, such as a tailgate or a vehicle door, forth in particular in order to shoot out a risk of injury in the event of an accident.

Finally exists Another disadvantage is that such actuation arrangements training a closed looking exterior body design, so the possible styling, adversely affect.

To avoid these disadvantages already exists a number of solutions, for example, in the DE 196 30 997 A1 , of the DE 197 22 503 A1 , of the DE 197 408 27 A1 and the GB 1,092,060 as well as the DE 42 39 166 A1 are described. However, the solutions mentioned show constructive disadvantages or the introduction of force in the opening movement, the treated in the documents arranged tailgate handle assemblies, not optimally designed.

A further development of these handle arrangements is from the DE 101 28 866 A1 known, which is designed for a cover-like component, in particular a tailgate of a motor vehicle. This handle assembly comprises a cover-like component with a, in its rest position a cover-side recessed handle covering, then on the recessed handle facing inside a grip element forming handle plate which is pivotable about an approximately parallel to the plane of the cover-like member pivot axis from the rest position to an operating position, in it protrudes from the levels of the lid-like component and the gripping element manually tangibly releases, wherein the pivot axis in the central region of recessed grip and handle plate extends, so that a region is received in the operating position of the recessed grip.

But also this solution, which already has a closed surface in terms of design Body offers, needed ultimately to release the tailgate an openable lock cylinder, so that while design and some design disadvantages are eliminated, however, there is an operation of the respective movable component with other manual activities afflicted.

However, to facilitate a manual operation for opening the respective movable components, so covers, hoods, flaps and / or doors of motor vehicles, would be an independent release and unlocking of the respective component, ie a lid, a hood, a flap and / or from doors in motor vehicles, very comfortable. From the DE 42 12 291 C2 It is already known to arrange a switching element in the region of the handle of the respective component, which detects a hand approaching the handle or a finger without contact by means of a sensor, even before the actual opening process is initiated. Already on detection of a finger, the sensor then generates a switching signal, which can be evaluated to trigger an automatic lowering of the window.

outgoing From this prior art, it is the object of the invention generic actuator a locking and unlocking device of a movable component in a motor vehicle to create in the outer design of the motor vehicle hardly appears and for the Operator a particularly comfortable handle for operating the offers each movable component.

The Task is solved by that an actuator a locking and unlocking device in a trip unit is arranged, which in its locking position a recess in the body shell almost complete covers, so that a closed design surface can be formed, wherein the Release and unlocking of a lock device of the supply and Unlocking device only in an unlocked position actuator is reached so that by a mechanical handle of the actuator alone a trigger at least one non-mechanical agent, whereby a release and indirect operation the lock device of the locking and unlocking device is executable and thereby the movable component is freely displaceable.

In preferred embodiment of the invention, the trip unit a carrier element arranged in or on the movable component, which comprises training in or at which the actuator and the mechanical means moved by the mechanical handle for triggering the non-mechanical means are arranged.

When Non-mechanical means come to release and / or authorization request / authorization check at least a sensor element and / or an antenna element is used.

When the unlocking triggering Element is a switch element in or on the support element arranged, which finally after release and / or authorization check by the sensor element and / or the antenna element unlocks the movable component.

The Sensor element is also arranged in or on the carrier element. The Antenna element, which is the authorization of, for example, a KeylessEntry system and a subsequent release for unlocking the locking device can, both in or on the carrier element as well as in a Close range can be arranged within the movable component.

In Another preferred embodiment of the invention is for triggering the Switch element on a carrier element-functional element a shaft rotatably disposed on a shaft axis passing through Carrier element recesses cross Carries fasteners over which the operating direction rotatable within the carrier element box displaced from the locking position to the unlocked position is, wherein at least one end of the shaft arranged a switching cam is that excites the switch element in the unlocked position, in particular, a microswitch can be used.

In Another preferred embodiment of the invention is in the carrier element receiving openings a sensor element arranged, which is the authorization of the actuator actuating handle, checks and the unlocking of the lock device releases, wherein the sensor element as an approximation sensor and / or an infrared sensor and / or a photoelectric sensor system and / or a biometric sensor can be formed.

Prefers is that the locking and unlocking device by pressing the actuator from the locking position to the unlocking position Unlocking the lock device causes, with at least one transmitted from the switch element outgoing signal to a switching module is, whose output leads to the circuit of unlocking the lock device, wherein the respective release of the sensor element and / or the antenna element the signal of the switch element is superimposed. The overlay ensures that the switch element unlocking the lock device only when the sensor element the authorization of the actuating Handle checked has and / or if the antenna element has the authorization check in the outer vicinity recognizes an access authorization system located therein. Of course it is the invention also without the ability to release the sensor element and / or antenna element executable.

With regard to the design, the invention has the advantage that the actuating device is arranged in the locking position almost gap-free and flush in the body outer skin, wherein carrier element connecting surfaces are formed, which allow attachment of the support element of the trip unit to an inner wall of the body shell. In addition, the aerodynamic properties of the body shell are particularly favorable, since it is ensured during driving of a motor vehicle that the body shell is closed flat and almost gap-free. It does not depend on the operator of the actuator, because a provision of Be when the operator's handle is finished, ie as soon as the operator gets into the vehicle.

Prefers is that the body shell at least a partial overlap of the carrier element guaranteed so that from an eye of the observer, only the actuator in its unlocked position or locking position is visible.

From particular advantage is a design surface of the body shell, the aesthetic or other reasons already has a projection in the outer skin, so that the trip unit the locking and unlocking device below this projection can be arranged and thus a normal sized viewer the trip unit below the projection in the movable component, for example in a vehicle door, at all does not perceive.

The Locking and unlocking device allows the operator through Sheer Flaps of the actuator a release and unlocking of the locking device of the locking and unlocking device causes, so that the operator only the movable component in the desired To move position needs to move without further mechanical components to have to. For this are within of the carrier element the trip unit handlelike Recesses for a clean grip of the handle of the operator to open and Shut down arranged the movable component.

In preferred embodiment would the actuator by a reset device, in particular a return spring, from the unlocked position back to the locking position moves as soon as the operator releases the handle on the actuator has finished.

Finally is the shaft of the actuator arranged near the lower region of the carrier element box, allowing a folding movement of the actuator in the vehicle into executable is, with the hand of an operator preferably with the palm after above the handle for releasing and unlocking the locking and unlocking device causes, so that the corresponding recesses to achieve a clean grip of the hand in the upper interior of the support element are positioned.

Further preferred embodiments of the invention will become apparent from the others, in the subclaims mentioned features.

Below the ledge 38 is a trip unit 10 arranged, which serves to trigger the locking and unlocking of the vehicle door and on a, also belonging to the locking and unlocking schematically illustrated lock device 40 acts. How out 1 becomes apparent from the eye of an observer 34 the trip unit 10 in the design area 36 below the ledge 38 not visible.

The trip unit 10 However, it is also designed so that even from a lower position, the depression 14 in which the trip unit 10 is arranged, not visible, as by an actuator 12 the trip unit 10 a closed design area 36 is trained.

The further details to the locking and unlocking device go from the 2A . 2 B and 3 but where 1 already shows that not mechanical means 16 . 18 . 20 the trip unit 10 on a switching module 44 act, the non-mechanical means 18 both in the trip unit 10 as well as inside the vehicle door can be arranged and therefore as 18 and 18 ' is shown twice.

Depending on a signal from a KeylessEntry system 42 is starting from the switching module 44 a reaction to the lock device 40 Executable, after pressing the in the trip unit 10 arranged Betätigungsvorrich tung 12 the door as an exemplary selected movable component 30 makes it freely relocatable.

On the in 1 shown non-mechanical means 16 . 18 . 20 to release the locking device 40 becomes after explanation of the trip unit 10 once again detailed.

3 shows in a detailed view of the components of the trip unit 10 ,

The trip unit 10 comprises a carrier element 22 which consists of a carrier element box 22A , a carrier element functional element 22B , a carrier element connecting surface 22C a support member receiving opening 22D , a carrier pickup shoe 22E and a carrier element recess 22F is trained.

The carrier element box 22A is open to the body shell and has in this opening the actuator 12 , in the embodiment in the form of a flat flap 12 , which is modeled on the contour of the body shell.

This flap 12 is in 3 in a locking position VP (dotted line) and in an unlocking position EP (dashed line). The flap is made of fasteners 28 worn on a shaft 24 are arranged, the shaft 24 again on the inside of the carrier element-functional element 22B is arranged.

The wave 24 is by handle on the flap 12 by a rotation angle α, as shown by the arrow, around a shaft axis AA in the carrier element box 22A in displaceable, with at least one end on the shaft 24 a switching cam 26 is arranged, which is a micro-switch 20 operated as a switch element, which serves to switch the unlocking of the lock device.

The microswitch 20 is in the carrier pick-up shoe 22E outside on the carrier element 22 arranged. A first connection line 46 connects the switch element 20 , the microswitch, with the in 1 illustrated switching module 44 and can the lock device 40 activate such that unlocking of the vehicle door shown by way of example takes place.

The invention additionally has carrier element receiving openings 22D on, in which at least one sensor element 16 is arranged, wherein the sensor element 16 this is done by the authorization check of the trip unit 10 operator and grant a release.

As a sensor element 16 which is on the carrier element 22 is indicated only schematically, come proximity sensors or infrared sensors and / or a light barrier sensor system and / or a biometric sensor in question, depending on the configuration, an arrangement in or on the support element 22 is executable. In any case, the handle reaches, in the form of the operator's hand, by engaging the palm of the hand up the upper portion of the support element 22 , so that, as stated here in the embodiment, an approximate sensor 16 performs an authorization check and the release via a second connection line, not shown 46 via the switching module 44 to lock device 40 gives.

As already described above, but in 3 not shown, may further be an antenna element 18 within the trip unit 10 be arranged, which also performs an authorization check and release for unlocking the lock device 40 there after a KeylessEntry system 42 through the antenna element 18 has been tested.

After successful handling of the actuator 12 , from the lock position to the unlock position with rotation of the shaft 24 to the predetermined angle α, the provision of a return device, in particular a return spring is performed, which in the 3 also not shown.

To the trip unit 10 to attach from the inside to the body shell are on the support element 22 , Carrier connection surfaces 22C trained, which allow a connection to the body shell. Of course, the carrier element box 22A be produced as a prefabricated component already with the production of the body shell as a prefabricated component with the body shell.

The 2A and 2 B show again with the same reference numerals, the trip unit 10 , both figures a view from above of the trip unit 10 enable. It should be clarified that the areas of the trip unit 10 that the actuator 12 , in particular the carrier element connecting surfaces 22C surrounded by the body outer skin of the mobile component 30 , here a door leaf shown as a dark surface, are covered. This cover 32 is in 2A shown transparently, so that the viewer in reality also for the overlap 32 must present a closed, almost gap-free education.

In any way, the coverage is 32 so executed that the underneath, now visible, connecting elements in the support element 22 for holding the flap 12 not visible in reality.

As a result, the inside of the trip unit 10 trained door handle recess so a combination of closed design surface 36 with comfortable technology for, opening the movable component 30 , In the locking position, the formed trough is through the actuator 12 completely closed and can therefore follow the ideas of design. Only on actuation of the actuator 12 inside the trough is released, the actual unlocking of the lock device 40 about the triggering of the switch element 20 he follows. The corresponding permission of the KeylessEntry system 18 . 42 or the selectable sensor elements 16 However, it will be checked in advance, after which an appropriate release will take place.

Alternatively to the in 1 to 3 A solution is also conceivable in which already after detection of the KeylessEntry system 42 in the outer vicinity of the movable component 30 , for example by the antenna elements 18 . 18 ' , a circuit takes place in which the actuating device 12 already self-powered motor is screwed, but with the switch element 20 , here the micro-switch, although excited, but is switched so that no unlocking the lock device 40 is effected.

In this case, an unlocking the lock device 40 only after authorization check and release via at least one arranged sensor element 16 by inserting the hand into the carrier element box 22A the trip unit 10 to be possible.

Only when the authorization check and release of the handle by at least one differently arranged sensor element 16 is done, then the switch element 20 cause a release of the door.
