Description
The invention relates to an actuating device for a door unlocking and/or opening mechanism. The invention also relates to a method for producing such an actuating device.
Door unlocking and/or opening mechanisms are known, for example, in certain vehicles, in which the lock of a vehicle door is unlocked electrically. An actuating device is provided, by means of which the driver can activate the door unlocking and/or opening mechanism.
The object of the present invention is to provide an actuating device for a door unlocking and/or opening mechanism which is improved over the prior art, and a suitable method for producing such an actuating device.
The solution of the invention for achieving the above object in respect of the operating device is characterized by what is presented in claim 1. The solution of the invention for achieving the above object in respect of the method is characterized by what is presented in claim 15.
The actuating device for a door unlocking and/or opening mechanism according to the invention comprises at least a housing, an actuating element having an actuating travel from a starting or inoperative position to an actuating position, and at least one resetting element which resets the actuating element from the actuating position to the starting position, wherein the actuating element is arranged opposite the housing and is arranged movably relative to the housing between the inoperative and/or starting position and the actuating position, and the at least one resetting element is arranged in at least one region between the actuating element and the housing.
The actuating element is arranged, for example, in a region of the vehicle door that is visible to the user or at least accessible to the hand for actuation. The housing comprises a detection unit, in particular a contactless detection unit, for detecting a movement of the actuating element for opening the door lock. The detection unit is at least partially or completely surrounded by the housing. The actuating element is arranged on the housing such that it is arranged opposite the detection unit. The detection unit may be constructed as a capacitive, inductive, mechanical or optical sensor.
In one embodiment, the reset element is adapted to interconnect the actuating element and the housing together and to seal the detection unit outwards, wherein the reset element acts in the direction of resetting the actuating element into the inoperative and/or starting position.
The restoring element has a connecting function, in particular an adhesive, sealing and elastic function, between the actuating element and the housing. The adhesive function is produced by: during the production of the actuating device, the restoring element is already joined as a piezoelastic material to the actuating element and the housing material in a bonded manner. Furthermore, the arrangement of the restoring element between the housing and the actuating element provides a sealing function, in particular for elements arranged in the actuating device, for example the detection unit. The spring function is produced by a defined compression characteristic of the restoring element, for example a compression-elastic material, which follows the movement of the restoring element when the actuating element is actuated and when the actuating element is restored from the actuating position into the starting or non-use position.
With a restoring element arranged in this way, the production costs and the installation space requirement of the actuating device can be reduced compared to conventional actuating devices. Furthermore, the operational reliability is improved.
In one possible embodiment, the restoring element is designed as a pressure-elastic element or as a pressure-elastic material, in particular as a pressure-elastic foam mat or as a pressure-elastic foam layer. This enables a quick and wear-resistant resetting of the actuating element. Furthermore, tolerances, in particular manufacturing and/or assembly tolerances, can be compensated and defined actuation or working strokes of the actuating device can be set.
The restoring element is in particular designed as a closed-cell foam layer or foam bun.
According to a further embodiment, the restoring element is designed as a foam line, in particular as a sealing line. The restoring element is formed in particular from a material which can be elastically compressed reversibly several times.
In particular, the restoring element can be arranged along a housing edge between the housing and the actuating element on this housing edge. Thereby, the detection unit arranged in the housing is protected from external stress.
For simple and reliable detection of the actuating movement, the actuating element is arranged on the housing such that it is arranged opposite a detection unit arranged in the housing.
Such a reset element has excellent sealing and compression properties. The restoring element is, for example, a flexible foam made of polyurethane. Wherein the restoring element is characterized by a good reversible compressibility.
According to one embodiment, the restoring element interconnects the housing, in particular the flexible element, and the actuating element in at least one region. The flexible element is connected to the actuating element, in particular by means of a restoring element, in a bonded manner. Furthermore, the restoring element can completely fill at least one region between the at least one flexible element and the actuating element. This achieves an excellent sealing function.
The material-bonded connection of the restoring element to the housing and to the actuating element results in a complete structural unit. The connection is designed such that the pressure-sensitive element, in particular the foam mat, or the pressure-sensitive material, in particular the foam layer, is bonded directly to the actuating element and to the housing. For this purpose, a plurality of point-like connections assigned to the surface between the actuating element and the housing can be used. The piezoelastic material or the piezoelastic element is connected in a bonded manner to the actuating element material on the side facing away from the actuating side and to the housing material on the side of the housing facing the actuating element. The actuating element is in particular shaped and/or dimensioned such that the restoring element is covered.
The reset element is in particular designed to be at a height which, in the inoperative and/or starting position of the actuating element, presets the distance between the housing and the actuating element. The height formed by the distance between the housing and the actuating element corresponds in particular at least to the actuating travel of the actuating element. The reset element thus determines the actuating travel of the actuating element, in particular in the hardened state.
According to one refinement, a stop element is provided for adjusting the distance between the actuating element (in particular from the starting position to the actuating position) and the housing (in particular from the relaxed position to the tensioned position) corresponding to the actuating travel. In a development of the actuating device, the stop element is designed to be elastic. This allows tolerances, in particular manufacturing and/or installation tolerances, to be compensated for.
In one possible embodiment, the stop element is part of a flexible element. As an alternative, the stop element can be formed on the upper edge region of the housing.
The flexible element is in particular designed as a spring element, for example as an elastic pressure arm or an elastic pressure strip, wherein the actuating element presses against a stop element formed on the flexible element or on the housing at the end of the actuating stroke. Furthermore, the flexible element may be integrally formed with the housing of the steering device. The flexible element projects inwardly from the edge region into the housing opening, for example at the open end of the u-shaped housing. In particular, at least two oppositely arranged flexible elements are provided which project inwardly from opposite sides of the housing in the direction of the housing opening, in particular at an angle of 90 °.
According to one embodiment, two horizontally oppositely arranged and mutually spaced flexible elements are provided, wherein the actuating strip of the actuating element extends between the oppositely arranged and mutually spaced free ends of the flexible elements. As an alternative or in addition to the flexible element itself and the optional trigger element, this actuating strip can serve as a trigger element and be operatively coupled to the sensor.
Alternatively, the flexible element can be arranged as a leg spring on an edge region of the u-shaped housing, on which the actuating element can be movably arranged. The flexible element is formed integrally with the housing, whereby a particularly simple manufacture of the operating device is ensured, as well as a mechanical stability of the flexible element.
Furthermore, the respective flexible element may have a stop element. The stop element (also referred to as support element) is constructed, for example, as a projection, in particular a stop surface or a support surface, for example a wedge surface or a channel-like arched structure, on the surface side of the flexible element facing the actuating element, on an upper edge region of the housing facing the actuating element, or on the surface side of the actuating element facing the flexible element, in particular on the inner surface side.
The aforementioned resilience, arrangement and fastening of the restoring element enables the restoring element or elements to be deformed under force, in particular when the actuating element is actuated in the direction of the restoring element. A sensor, in particular a distance sensor, for example a capacitive or inductive sensor, which is arranged in the housing, can detect this deformation and/or movement as a trigger or actuating signal and supply it to a control unit of the door unlocking and/or opening mechanism. In this way, the resetting element itself can form the triggering element which is in operative connection with the sensor. Alternatively or additionally, the reset element can be operatively coupled to a separate trigger element arranged in the housing, which trigger element in turn is operatively coupled to the sensor.
In the inventive method for producing an actuating device for a door unlocking and/or opening mechanism, at least one actuating element and a housing with an optional flexible element are provided, wherein the material of the restoring element is introduced in the region of the flexible element and the actuating element is moved and pressed in the direction of the stop element until it abuts against the stop element, which corresponds to the operating position of the operating element, so that the material of the resetting element is compressed and dispensed, and wherein the flexible element is configured to be elastic in such a way that it automatically returns the actuating element from the actuating position to the inoperative and/or starting position when it is not actuated, wherein the distance thus produced between the housing and the actuating element corresponds at most to the actuating travel of the actuating element, and wherein the material of the resetting element is hardened in the inactive and/or starting position.
For example, the material of the restoring element is applied to the surface side of the flexible element facing the actuating element, and then the actuating element is arranged on the flexible element, which is, for example, integrally formed with the housing. Subsequently, the actuating element is pressed against a stop element of the flexible element or of the housing, so that a distance between the actuating element and the stop element and thus the housing is adjusted, which distance corresponds to an operating or actuating stroke of the actuating device. Subsequently, the material of the restoring element hardens in the position of the actuating element which is restored to the inoperative or starting position. The working/operating stroke is thus defined on the basis of the distance produced by the restoring element which can be compressed in normal operation, so that tolerances, for example manufacturing, mounting and/or component tolerances, are compensated.
In an alternative method for producing an actuating device for a door unlocking and/or opening mechanism, which actuating device does not comprise any flexible element, at least the actuating element and a housing having the stop element, for example in the form of a stop rib projecting out of the housing, are provided, wherein material of a restoring element is introduced between the actuating element and the housing in the region of the stop element and the actuating element is moved and pressed from a first production position in the direction of the housing until it abuts against the stop element in a second production position, which corresponds to an actuating position, in order to compress and distribute the material of the restoring element between the housing and the actuating element, and wherein the material of the restoring element is designed such that, when not actuated, the restoring element automatically restores the actuating element from the second production position to the first production position as a result of material expansion, the first production position corresponds to a rest and/or starting position of the actuating element, wherein the material of the restoring element expands and hardens in the restored first production position, and the distance between the stop element and the actuating element, which is produced and formed in the hardened state of the material of the restoring element, corresponds to the actuating travel of the actuating element.
The return element is therefore designed in such a way that it performs an adhesive function, a sealing function and a return function, in particular a spring function. For this purpose, the restoring element can likewise be elastically compressed in the hardened state. The reset element may in particular automatically reset from the compressed state to the decompressed state.
The hardened restoring element is in its inoperative and/or starting position, for example, in a neutral position, in particular a decompressed neutral position, in which the actuating element is not actuated. The thickness of the hardened restoring element corresponds substantially to the working/actuating travel defined during manufacture and is determined by the distance between the stop element and the actuating element in the hardened and decompressed state of the restoring element. In the compressed state of the hardened restoring element and in the actuating position of the actuating element, the actuating element strikes the stop or the support element, wherein the restoring element is compressed. If the actuating element is no longer actuated, the resetting element is reset to its starting or non-use position on the basis of its resetting capability when the actuating element is relieved of pressure, wherein the actuating element is forcibly reset to its non-actuated position.

Fig. 1 shows a block diagram with a vehicle door 1, which comprises a door unlocking and/or opening mechanism 2.
The vehicle door 1 is a component of a vehicle, not shown in detail, such as a vehicle side door or a vehicle tailgate. For opening the vehicle door 1, this vehicle door has a door unlocking and/or opening mechanism 2.
The door unlocking and/or opening mechanism 2 comprises an actuating device 3 for a door handle 6, in particular an outside door handle, a door lock 4, in particular an electrically controlled door lock 4, and a control unit 5.
The handling device 3 is shown and described in detail in fig. 3 and 4. The actuating device 3 is in particular suitable for detecting an actuation of, for example, a door handle 6 for unlocking and/or opening the vehicle door 1 and for transmitting it to the control unit 5. The actuating device 3 transmits in particular an opening signal s1 to the control unit 5, which thereupon transmits a control signal s2 to the door lock 4, which is thereby unlocked, so that the vehicle door 1 is opened.
Fig. 2 shows a block diagram with a vehicle door 1 and an actuating device 3 arranged in the region of a door handle 6. The actuating device 3 is arranged, for example, on the outer side of the door handle 6 or on the side of the door handle 6 facing the vehicle door 1. As an alternative, the actuating device 3 can be arranged in the region of a (not shown) latching recess which is incorporated into the vehicle outer skin of the vehicle door 1. The detent recess can be arranged in any region of the vehicle skin panel. For example, the catch recess is arranged in the region of a vehicle skin of the vehicle door 1 which is arranged opposite the door handle 6.
Fig. 3 and 4 show perspective views of the handling device 3. Fig. 3 shows the actuating device 3 in a first production position M1, which in the finished state of the actuating device 3 corresponds substantially to the inoperative and/or starting position P1 of the actuating element 3.1. Fig. 4 shows the actuating device 3 in a first production position M2, which in the finished state of the actuating device 3 likewise corresponds substantially to the actuating position P2 of the actuating element 3.1.
The actuating device 3 comprises at least one actuating element 3.1, a housing 3.2 for a detection unit 7 for detecting an actuating movement of the actuating element 3.1. Furthermore, the actuating device 3 can comprise two flexible elements 3.3 for adjusting the actuating travel BH. Instead of two flexible elements 3.3, only one flexible element 3.3 or more than two flexible elements 3.3 may also be provided. The number of flexible elements 3.3 depends on the type, size, shape and/or function of the manipulator 3.
The actuating element 3.1 is arranged in a region of the vehicle door 1 that is visible to the user or at least accessible to the hand for actuation.
The resetting element 3.4 is adapted to, in the intended use, reset the operating element 3.1 from the operating position P2 to the inoperative and/or starting position P1. The actuating element 3.1 is arranged opposite the housing 3.2 and in particular opposite the detection unit 7, and is arranged movably relative to this housing 3.2 between a rest and/or starting position P1 and an actuating position P2. Furthermore, at least one restoring element 3.4 is arranged in the region between the actuating element 3.1 and the housing 3.2.
The actuating element 3.1 is arranged on the housing 3.2 in such a way that it is arranged opposite a detection unit 7 which is at least partially enclosed by the housing 3.2. The detection unit 7 may be constructed as a capacitive, inductive, mechanical or optical sensor.
Furthermore, the actuating device 3 comprises a restoring element 3.4 which is suitable for connecting the actuating element 3.1 and the housing 3.2 to one another and for sealing the detection unit 7 to the outside, wherein the restoring element 3.4 acts in the direction of restoring the actuating element 3.1 into the inoperative and/or starting position P1.
The actuating element 3.1 is substantially plate-shaped. The actuating element 3.1 has a u-shaped cross section.
Furthermore, the actuating device 3 comprises a housing 3.2 on which the actuating element 3.1 can be movably arranged.
In the embodiment shown, the housing 3.2 has a u-shaped cross-section. The actuating element 3.1 and the housing 3.2 are arranged opposite one another with open ends and are stacked on top of one another such that their respective wall regions 3.1.1 and 3.2.2 are arranged overlapping and parallel to one another. The actuating element 3.1 is placed on the housing 3.2 such that the wall region 3.1.1 of the actuating element 3.1 forms the outer wall of the actuating device 3 and the wall region 3.2.2 of the housing 3.2 is the inner wall of the actuating device 3.
The housing 3.2 may also have at least two inwardly directed flexible elements 3.3 in the edge region 3.2.1 of the open end. The flexible element 3.3 is designed, for example, as a spring element, in particular an elastic pressure arm, a pressure bar or an elastic leg element, in particular a leg spring, which protrudes inward from the edge region 3.2.1 of the housing 3.2 which is open at the top. In the relaxed state of the flexible elements 3.3, these project inwardly away from the wall region 3.2.2 at an angle of 90 °.
The actuating element 3.1 has a possible actuating path BH (shown in fig. 3) from a rest or starting position P1 (shown in fig. 3) to an actuating position P2 (shown in fig. 4).
The flexible elements 3.3 are used for producing the actuating device 3 and are designed in such a way that they cause the actuating element 3.1 to return from the second production position M2 shown in fig. 4 to the first production position M1 shown in fig. 3 if the actuating element 3.1 is no longer actuated.
The first manufacturing position M1 corresponds substantially to the inoperative and/or starting position P1 of the operating element 3.1. The inoperative and/or starting position P1 of the actuating element 3.1 is in particular dependent on the expansion/solidification behavior of the material for the restoring element 3.4 and can be higher or lower than the housing 3.2.
Furthermore, at least one restoring element 3.4 is arranged in at least one region B between the respective flexible element 3.3 and the actuating element 3.1. The restoring element 3.4 is formed from a piezoelastic material and can be compressed reversibly a plurality of times. The restoring element 3.4 is formed, for example, from an elastically compressible material which can likewise be elastically compressed even in the hardened state. The restoring element 3.4 is in particular formed from a certain elastically compressible material, so that the restoring element 3.4 can automatically be restored from the compressed state to the decompressed (uncompressed) state even in the hardened state after the production of the actuating device 3.
In this case, the restoring element 3.4 in the uncompressed state, in particular its height H, presets a distance a between the housing 3.2 and the actuating element 3.1 in the inoperative and/or starting position P1 of the actuating element 3.1. The distance a between the housing 3.2 and the actuating element 3.1 forms a height H which corresponds in particular to at least one actuating travel BH of the actuating element 3.1. The reset element 3.4 thus determines the actuating travel BH of the actuating element 3.1, in particular in the hardened state.
The height H is greater than the actuating path BH during the production of the actuating device 3, in particular in the not yet hardened state of the material of the restoring element 3.4. In the hardened state of the material of the restoring element 3.4, the height H between the housing 3.2 and the actuating element 3.1 corresponds to the thickness of the hardened material of the restoring element 3.4, wherein the thickness of the hardened material of the restoring element 3.4 again corresponds approximately to the actuating travel BH.
The restoring element 3.4 is formed, for example, from a closed-cell foam, for example a flexible foam made of polyurethane. The restoring element 3.4 makes it possible to optimally isolate the actuating device 3 from external influences.
In particular, the detection unit 7 covered by the actuating element 3.1 can be protected. The detection unit 7 is a sensor, in particular a control sensor, for detecting a control of the control element 3.1, for example a capacitive or inductive sensor, a distance sensor or a pressure sensor. The detection unit 7 is arranged in an interior of the housing 3.2 formed between the actuating element 3.1 and the housing 3.2. The detection unit 7 is arranged and held in particular within the activation region AB of the actuating device 3.
The flexible elements 3.3 project with their free ends 3.3.1 inward, so that these free ends 3.3.1 are arranged opposite one another in a plane and spaced apart from one another. The actuating strips 3.1.2 of the actuating element 3.1 project into the free space thus formed between the free ends 3.3.1 of the flexible elements 3.3. The actuating element 3.1 rests in particular against the free end 3.3.1 of the flexible element 3.3. The free end 3.3.1 has a larger cross-section than the flat sides or legs 3.3.2 of the flexible element 3.3. The stability of the actuating device 3 in the triggering region AB of the actuating device 3 is increased by the increased cross section of the free end 3.3.1 of the flexible element 3.3.
The housing 3.2 surrounds the detection unit 7 on the side facing away from the actuating element 3.1 and is, for example, a one-piece plastic housing. Thereby, the detection unit 7, for example a distance sensor, in particular a capacitive or inductive sensor, arranged inside the housing 3.2 is protected.
Furthermore, the restoring elements 3.4 are elastic so that, as shown in the sequence of fig. 3 and 4, for example in the actuating direction BR, they follow the movement of the actuating element 3.1 when this actuating element is actuated. The reverse sequence of fig. 4 and 3 shows the resetting movement RB of the actuating element 3.1 back into the inoperative or starting position P1 as an example.
For adjusting the actuating travel BH of the actuating element 3.1, in particular from the starting position P1 to the actuating position P2, a stop element 8 is provided.
In one possible embodiment, the stop element 8 is arranged between the actuating element 3.1 and the flexible element 3.3. The stop element 8 is in particular integrally formed with the flexible element 3.3. As an alternative, the stop element 8 is formed integrally with the actuating element 3.1 (not shown in detail) or with the housing 3.2, in particular with the upper edge region or wall region 3.2.2.
The stop element 8 is formed, for example, as a projection, in particular a stop surface or a support surface, for example a wedge surface or a channel-like arched structure, on the surface side of the flexible element 3.3 facing the actuating element 3.1 and/or on the upper wall region 3.2.2.
The aforementioned elasticity, arrangement and fastening of the restoring element 3.4 enable the restoring element or elements to be deformed under force, in particular when the actuating element 3.1 is actuated in the direction of the detection unit 7. A detection unit 7, for example a sensor, in particular a distance sensor, arranged in the housing 3.2 can detect this deformation and/or movement and detect it as a trigger or actuating signal and supply it to the control unit 5 of the door unlocking and/or opening mechanism 2. The resetting element 3.4 itself can thus form a triggering element which is in operative connection with the detection unit 7. Alternatively or additionally, the resetting element 3.4 can be operatively coupled to a separate trigger element arranged in the housing 3.2, which trigger element is in turn operatively coupled to the detection unit 7.
As fig. 4 shows, during the production of the actuating device 3, the material of the restoring element 3.4, in particular the foam material or the foam mass, is applied to the flexible element 3.3 at least in the region B of the stop element 8 without being compressed. The material of the restoring element 3.4 can likewise be introduced between the flexible element 3.3 and the actuating element 3.1, which are positioned relative to one another, in the region B of the stop element 8. The flexible element 3.3 is relaxed and the flexible element 3.3 and the steering element 3.1 are positioned relative to each other in the first manufacturing position M1. Subsequently, the actuating element 3.1 is displaced and pressed in the direction of the flexible element 3.3 until it abuts against the stop element 8, so that the material of the restoring element 3.4 is compressed and dispensed.
The flexible element 3.3 is designed to be elastic in such a way that, when not actuated, it automatically returns the actuating element 3.1 from the second production position M2 to the first production position M1, which corresponds approximately to the inoperative and/or starting position P1 of the actuating element 3.1, wherein the material of the return element 3.4 expands and hardens in this returned first production position M1, and the distance a thus formed between the housing 3.2, in particular the stop element 8, and the actuating element 3.1 in the hardened state of the material of the return element 3.4 corresponds to the actuating travel BH of the actuating element 3.1.
The restoring element 3.4 has an adhesive function, a sealing function and a restoring function, in particular an elastic restoring function. The adhesive function is produced by: when the restoring element is applied to the flexible element 3.3 and the actuating element 3.1 is pressed down, the restoring element 3.4 is already connected to the actuating element 3.1 and the flexible element 3.3 in a bonded manner. The arrangement of the restoring element 3.4 in the intermediate space between the actuating element 3.1 and the flexible element 3.3 forms a sealing function, in particular for elements arranged in the actuating device 3, for example the detection unit 7. The restoring function, in particular the elastic restoring function, results from the defined compression behavior of the hardened restoring element 3.4.
The flexible element 3.3 is used only for adjusting the actuating travel BH of the actuating element 3.1 during the manufacturing process. In the hardened state of the material of the restoring element 3.4, the flexible element 3.3 does not have any further function or effect.
Fig. 5A to 5C schematically show different views of an alternative embodiment of the actuating device 3 for a door unlocking and/or opening mechanism. In this embodiment of the actuating device 3, no flexible element 3.3 is provided.
Fig. 5A shows a perspective view of the actuating device 3 with the housing 3.2 and the built-in detection unit 7, without the actuating element 3.1.
Fig. 5B shows a perspective view of the actuating device 3 with the housing 3.2 and the built-in detection unit 7 and with the actuating element 3.1 arranged in the housing 3.2.
Fig. 5C shows an enlarged detail of the stop region between the actuating element 3.1 and the housing 3.2.
The actuating device 3 comprises at least an actuating element 3.1, a housing 3.2 for a detection unit 7 for detecting an actuating movement of the actuating element 3.1, and a resetting element 3.4 for resetting the actuating element 3.1 into its normal position, in particular into its inoperative and/or starting position P1.
The actuating element 3.1 is arranged opposite the housing 3.2 and in particular opposite the detection unit 7, and is arranged movably relative to this housing 3.2 between a rest and/or starting position P1 and an actuating position P2. The detection unit 7 is arranged and held in the housing 3.2, in particular opposite the housing opening 3.2.3.
The housing 3.2 can be designed as a housing shell or housing body with an upwardly open housing opening 3.2.3. The detection unit 7 can comprise an electronic detection device 7.1, which is arranged in the housing 3.2 in such a way that it is arranged opposite the housing opening 3.2.3.
The actuating element 3.1 is again arranged on the housing 3.2 in such a way that it is arranged opposite a detection unit 7 which is at least partially enclosed by the housing 3.2. The detection unit 7 may be constructed as a capacitive, inductive, mechanical or optical sensor.
The restoring element 3.4 is arranged in the region between the actuating element 3.1 and the housing 3.2. The restoring element 3.4 is arranged in particular along the housing edge 3.2.4 between the housing 3.2 and the actuating element 3.1 on this housing edge. The restoring element 3.4 is formed, for example, as a plastic wire, in particular a foam wire, for example, as a sealing wire, along the housing edge 3.2.4 between the housing 3.2 and the actuating element 3.1.
The restoring element 3.4 is designed such that it connects the actuating element 3.1 and the housing 3.2 to one another and seals the detection unit 7 to the outside, wherein the restoring element 3.4 acts in the direction of restoring the actuating element 3.1 to the inoperative and/or starting position P1.
The resetting element 3.4 is in particular suitable for resetting the actuating element 3.1 from the actuating position P2 into the inoperative and/or starting position P1 in the intended use.
The restoring element 3.4 is formed, for example, from a piezoelastic material and can be compressed reversibly a plurality of times. The restoring element 3.4 is formed, for example, from an elastically compressible material which can be elastically compressed even in the hardened state. The restoring element 3.4 is in particular formed from a certain elastically compressible material, so that the restoring element 3.4 can automatically be restored from the compressed state to the decompressed (uncompressed) state even in the hardened state after the production of the actuating device 3.
As shown in detail in fig. 5C, the housing 3.2 comprises a stop rib 8.1 which projects beyond the housing 3.2, in particular beyond the housing edge 3.2.4, as a stop element 8 for limiting the actuating movement of the actuating element 3.1. The inner edge of the housing edge 3.2.4 is, for example, higher than the housing edge 3.2.4 and is designed as a stop rib 8.1.
As regards the method of producing the actuating device 3 shown in fig. 5A to 5C, first of all an actuating element 3.1 and a housing 3.2 with a stop element 8 are provided.
Subsequently, the material of the restoring element 3.4 is introduced between the actuating element 3.1 and the housing 3.2 in the region of the stop element 8. In a further step, the actuating element 3.1 is moved and pressed from the first production position M1 in the direction of the housing 3.2 until it abuts against the stop element 8 in the second production position M2, which corresponds to the actuating position P2, so that the material of the restoring element 3.4 is compressed and dispensed between the housing 3.2 and the actuating element 3.1.
The material of the restoring element 3.4 is designed such that, when not actuated, this restoring element automatically restores the actuating element 3.1, as a result of material expansion, from the second production position M2 into the first production position M1, which corresponds to the inoperative and/or starting position P1 of the actuating element 3.1, wherein the material of the restoring element 3.4 expands and hardens in this restored first production position M1.
The distance a thus produced and formed between the stop element 8 and the actuating element 3.1 in the hardened state of the material of the reset element 3.4 corresponds to the actuating travel BH of the actuating element 3.1.
In the hardened state of the material of the restoring element 3.4, the height H between the housing 3.2 and the actuating element 3.1 corresponds to the thickness of the hardened material of the restoring element 3.4, wherein the thickness of the hardened material of the restoring element 3.4 again corresponds approximately to the actuating travel BH.
The material of the restoring element 3.4 is formed, for example, from a closed-cell foam, for example a flexible foam made of polyurethane. The resetting element 3.4 therefore optimally insulates the detection unit 7 from external influences.
In a similar sequence to that shown in fig. 3 and 4, in the hardened state of the material, the restoring element 3.4 is elastically compressed, so that this restoring element 3.4 follows the movement of the actuating element 3.1 when it is actuated.
The aforementioned material elasticity, arrangement and fastening of the restoring element 3.4 enable this restoring element to be deformed under force, in particular when the actuating element 3.1 is actuated in the direction of the detection unit 7. A detection unit 7, for example a sensor, in particular a distance sensor, arranged in the housing 3.2 can detect this deformation and/or movement and detect it as a trigger or actuating signal and supply it to the control unit 5 of the door unlocking and/or opening mechanism 2. The resetting element 3.4 itself can thus form a triggering element which is in operative connection with the detection unit 7. Alternatively or additionally, the reset element 3.4 can be operatively coupled to a separate trigger element arranged in the housing 3.2, which in turn is operatively coupled to the detection unit 7.
