Description

FIELD OF INVENTION

The present invention relates to the opening and closing of motor vehicle doors and, in particular, to a positioning module for a motor vehicle door and to a motor vehicle door module.

BACKGROUND OF THE INVENTION

In connection with increased user comfort, there are suggestions for opening vehicle doors using an electric drive. For example, WO 2017/160787 A1 opening the vehicle door into a slightly raised position. However, it has become apparent that there is a need for more compact units.

US 2018/179788 A1 describes, in summary, a door presentation system for pivoting a vehicle door relative to a vehicle body between a closed position and a partially opened extended position. The door presentation system includes a presentation assembly attached to one of the vehicle body and the vehicle door, with an auxiliary striker connected to the other of the vehicle body and the vehicle door. The presentation assembly includes an extendable member configured to move between retracted and extended positions corresponding to the closed and extended positions, and an auxiliary locking mechanism which movable between locked engagement with the auxiliary striker when it is indicated that the vehicle door is not under manual control of a user to enable automatic return of the vehicle door to the closed position, and unlocked engagement from the auxiliary striker when it is indicated that the vehicle door is under manual control of a user to enable the door to be moved to the fully open position.

EN 10 2017 117728 A1 describes, according to the summary, a motor vehicle lock arrangement for a motor vehicle door adjustably coupled to a motor vehicle body, wherein a motor vehicle lock is provided which, in the assembled state, is arranged on the motor vehicle door or on the motor vehicle body, wherein the motor vehicle lock arrangement, in particular the motor vehicle lock, has a pressing arrangement for exerting a driving force on the motor vehicle door in the opening direction thereof, so that the motor vehicle door can be adjusted in a motor-driven pressing process from a closed door position, in particular a main closed door position or a pre-locked door position, into a pressing door position further in its opening direction and an engagement gap can thereby be created between the motor vehicle door and the motor vehicle body. It is proposed that the pressing arrangement has a presser which, in the assembled state, carries out a pressing movement from an initial position into a pressing position as part of the pressing process and thereby adjusts the motor vehicle door to its pressing door position.

SUMMARY OF THE INVENTION

An object of the present invention is therefore to provide a door opener which enables improved user comfort with a compact design.

This object is solved by the subject matter of the independent claims. Further examples are given in the dependent claims. The following The aspects described also apply to the installation module for a motor vehicle door and to the motor vehicle door module.

According to the invention, a setting-up module for a motor vehicle door is provided. The setting-up module has a setting-up device with an actuator unit and a transmission element. The actuator unit is designed to move the transmission element between a retracted position and an at least partially extended position. The transmission element is designed to transmit a setting-up force for a motor vehicle door from the actuator unit via a free end of the transmission element when moving into the at least partially extended position. The transmission element is designed to be translationally movable. The setting-up device can be fastened to one of the group of motor vehicle door and body, and a holder can be fastened to the other of the group of motor vehicle door and body. The free end of the transmission element can be temporarily connected to the other of the group of motor vehicle door and body via the holder in order to releasably hold the motor vehicle door at least in one set-up position.

According to the invention, a releasable holding mechanism is provided so that the transmission element can be temporarily connected to the holder by means of a holding force which can be fastened to the other of the group of motor vehicle door and body. The releasable holding mechanism is designed to release the holding force in the raised position of the vehicle door in order to release the vehicle door for further opening.

According to the invention, the transmission element is also designed to transmit a closing force for the motor vehicle door from the actuator unit when moving from an extended position to the retracted position. The releasable holding mechanism has an adjustable holding force with at least a first holding force and a second holding force. The second holding force is greater than the first holding force. The first holding force is designed to hold the motor vehicle door in the raised position against unintentional further opening of the motor vehicle door. The second holding force is designed to enable the motor vehicle door to be closed. The releasable holding mechanism is designed to change at least from the first holding force to the second holding force and vice versa.

According to one example, the holder is designed as a mandrel with a widened end. The releasable holding mechanism has at least one movable gripping arm at the free end of the transmission element in order to grip behind the widened end of the mandrel in the closing direction. An actuating element for the at least one movable gripping arm is arranged in the transmission element, which can be brought into engagement with a release actuator in the region of an end of the transmission element opposite the free end in order to move the at least one movable gripping arm into a release position for the mandrel with the release actuator.

According to one example, the release actuator is a release lever that is movable with a separate actuator to release the mandrel. The release lever is engageable with the actuating element when the transmission element is in the extended position.

According to one example, the release actuator is a release lever provided on the transmission element and movable through a fixed stop to release the mandrel. The release lever abuts the stop when the transmission element is in the extended position.

According to one example, the release actuator is a release lever provided on the transmission element and movable by a movable stop to release the mandrel. The movable stop is movable with a separate drive to release the mandrel. The movable stop is engageable with the release lever in a region when the transmission element is extended and when it is in the extended position.

According to one example, the release actuator is a release lever provided on the transmission element and movable from one of a plurality of stops to the mandrel. The plurality of stops are arranged on a movable latch. The latch is movable perpendicular to the extension direction of the transmission element in the direction of the release lever to bring one of the stops into engagement with the release lever to actuate the release lever by movement of the transmission element.

According to one example, the holder has a receptacle, or is designed as a receptacle, for temporarily holding the extending free end of the transmission element, wherein the free end has a coupling region which is designed to protrude at least partially into the receptacle.

The receptacle has at least one clamping unit with an actuator to hold the coupling area in a clamping manner so that a releasable frictional connection can be created in relation to the holding direction. At least one movably held clamping element is provided which can be pressed against the coupling area with an adjustable force. A first force and a second force are adjustable to generate the first holding force and the second holding force.

According to one example, in a holding state, the free end of the transmission element with the coupling region projects into a first region of the receptacle and the receptacle has a second region adjacent to the first region into which the coupling region can be displaced in the event of an overload situation.

In one option, the clamping unit has at least one clamping element which is held with an eccentric disc which is adjustable via an actuator to provide different holding forces.

In another option, the clamping unit has two movably held clamping elements, both of which are movable with an adjusting disk that is adjustable via an actuator to provide different holding forces.

According to one example, the free end of the transmission element is designed with a widening coupling region, and the receptacle has at least two movable holding elements to at least partially encompass the coupling region, so that a releasable, positive connection can be created with respect to the holding direction. The two movable holding elements act on the coupling region with an adjustable force. A first force and a second force can be adjusted with an actuator in order to generate the first holding force and the second holding force. The holding elements can be moved with the actuator in a release direction in order to release the holding force. The first and second forces are designed such that the receptacle releases the coupling region in an overload situation.

According to the invention, a motor vehicle door module is also provided. The motor vehicle door module has a mounting module according to one of the preceding examples and a support structure of a motor vehicle door. One of the group of the mounting device and the holder is held on the support structure. The other of the group of the mounting device and the holder is designed for fastening to a body region of the motor vehicle.

The actuator is, for example, an electrical actuator, for example as a linearly operable electromagnetic actuator (electromagnetic actuator) or as a rotary-operable electromagnetic actuator (electric motor).

According to one aspect of the invention, a stand is provided which can also releasably hold the vehicle door in the open state.

DETAILED DESCRIPTION OF EMBODIMENTS

Fig.1 shows an example of a setting-up module 10 for a motor vehicle door in a schematic sketch. The setting-up module 10 has a setting-up device 12 with an actuator unit 14 and a transmission element 16. The actuator unit 14 is designed to move the transmission element 16 between a retracted position P1 and an at least partially extended position P2. The transmission element 16 is designed to transmit a setting-up force FA for a motor vehicle door from the actuator unit 14 via a free end 18 of the transmission element when moving into the at least partially extended position P2. The transmission element 16 is designed to be translationally movable. The setting-up device 12 can be attached to the motor vehicle door or the body. A holder 20 can be attached to the body or the motor vehicle door. The free end of the transmission element 16 can be temporarily connected to the motor vehicle door or the body via the holder in order to releasably hold the motor vehicle door at least in an set-up position.

In Fig.1 A vehicle door is indicated by a dashed line 22. In the example, the mounting module 10 is attached to the body and the bracket 20 is attached to the vehicle door.

In one example, the transmission element is designed as a translationally movable latch which, in the extended position, is arranged with an extended region in an extension direction in order to transmit the setting-up force in an setting-up direction with a free end in this position.

The retracted position may also be referred to as the first position, retracted position or stowed position. The extended position may also be referred to as the second position, deployed position, extended position or displayed position. The extended position may also be referred to as the presentation position.

The presentation position can also be referred to as the gap position or grip position, in which a user can manually move the vehicle door to a wider, for example fully open, position. This is useful, for example, for vehicle doors that do not have an external door handle.

Fig.2 shows another example of a positioning module for a motor vehicle door in a perspective view. The positioning module has a primary electric motor 50 for the actuator unit 14. A gear 52 has several gears, one of which is designed as a gear 54 for driving the transmission element 16.

In one example, the transmission element 16 is designed as a translationally movable latch 56 which, in the extended position, is arranged with an extended region 58 (see Fig. 3A) in an extension direction in order to transmit the setting-up force in a setting-up direction with a free end 60 in this position.

In Fig.2 the bracket 20 is shown at a distance from the mounting module 10.

In one option, a releasable holding mechanism 62 is provided so that the transmission element 16 can be temporarily connected to the holder 20 by means of a holding force which can be fastened to the other of the group of motor vehicle door and body. The releasable holding mechanism is designed to release the holding force in the raised position of the vehicle door in order to release the vehicle door for further opening.

The transmission element 16 is also designed to transmit a closing force for the motor vehicle door from the actuator unit 14 when moving from an extended position to the retracted position. The releasable holding mechanism 62 has an adjustable holding force with at least a first holding force and a second holding force. The second holding force is greater than the first holding force. The first holding force is designed to secure the motor vehicle door in the raised position against unintentional further opening of the motor vehicle door. The second holding force is designed to enable the motor vehicle door to be closed. The releasable holding mechanism 62 is designed to change at least from the first holding force to the second holding force and vice versa.

Releasing the holding force is provided as an option.

One option provides that closing the motor vehicle door involves moving the motor vehicle door into a pre-latching position of a door lock of the motor vehicle door and then moving it further, thereby pressing the vehicle door against a door seal and moving the motor vehicle door into a main latching position of the door lock. The adjustability of the first holding force and the second holding force is provided as an option.

Fig.3 shows the installation module Fig.2 with the transmission element 16 extended. In this position, the holder 20 is held by the transmission element 16, for example to prevent it from being opened further inadvertently, for example if the vehicle is at an angle or if the vehicle door is slammed open by wind. The holder can be released to open the vehicle door further. The holder 20 can also be held in such a way that the holding force is only low and the user can manually push the vehicle door out of the holder. The vehicle door held in this position can also be closed again using the transmission element 16. For this purpose, a second, higher holding force can be made available, for example, at least for the area when the vehicle door is pressed against a surrounding door seal.

Fig.4 shows the installation module Fig.2 and Fig. 3A in different positions during the opening process of a motor vehicle door (viewed from top to bottom): First, a starting position is shown in which the transmission element 16 is in a retracted state. The holder 20 is arranged at a distance. The vehicle door (not shown) is in a closed or at least ajar position. / Next, the transmission element 16 extends slightly in order to at least rest against the holder 20. The vehicle door is still in the closed or ajar position. / After that, the holder 20 is held, for For example, the door is grasped in order to then begin the setting-up process, whereby the vehicle door moves from the closed or ajar position to the slightly open or extended position. / In an extended position, the bracket and thus the vehicle door is held on the transmission element 16. The vehicle door is in the slightly open or extended position. / The bracket can now be released for further opening. The vehicle door can be moved from the extended position to a further open position. / The transmission element 16 can then be retracted.

Fig.5 shows the installation module Fig.2 and Fig. 3A in different positions during the closing or closing process of a motor vehicle door (viewed from top to bottom): First, a starting position is shown in which the transmission element 16 is in a retracted state. The vehicle door is, for example, arranged in a further open position. / Next, the transmission element 16 extends to engage with the bracket 20 of the vehicle door. The vehicle door is arranged in the slightly open or extended position. / After that, the bracket 20 is held by the transmission element 16, for example grasped around, in order to then begin the closing process in which the vehicle door is slowly brought into the closed position. / In the retracted position, the bracket is released and the transmission element 16 is fully retracted. The vehicle door is in the closed position.

Fig.6 shows the installation module Fig.2 in detail in a retracted position. Fig.7 shows the installation module Fig.6 in an extended position with the vehicle door held and with a release mechanism. In a first option, the bracket 20 is designed as a mandrel 102 with a flared end 104. The mandrel 102 is attached, for example, to a plate which can be attached, for example, with screws, to the vehicle door or a body area.

The releasable holding mechanism 62 has at least one movable gripping arm 106 at the free end of the transmission element 16 in order to grip behind the widened end 104 of the mandrel 102 in the closing direction. In the transmission element 16, an actuating element 108 for the at least one movable gripping arm 106 is arranged, which can be brought into engagement with a release actuator 112 in the region of an end 110 of the transmission element 16 opposite the free end in order to move the at least one movable gripping arm 106 into a release position for the mandrel 102 with the release actuator 112.

In one example, the release actuator is provided as a release lever 114 that is movable with a separate actuator to release the mandrel 102. The release lever 114 is engageable with the actuating member 108 when the transmission member 16 is in the extended position.

The actuating element 108 is provided as an option. In an alternative, an actuator is provided for the at least one movable gripping arm 106, which is arranged in the transmission element 16, for example in the region of the extending end.

In the example shown, the releasable holding mechanism has two movable gripping arms 106 which grip the flared end of the mandrel from two sides.

The release actuator 112 is designed, for example, as a longitudinal rod or pin 113 which has an actuating projection 116 at its rear end. The pin 113 is held at its rear end in a receptacle 115 which forms a stop in the inserted position of the pin 113. The receptacle 115 forms a guide for the end of the pin 113.

In the extended state of the transmission element 16, the actuating projection 114 is located in an engagement region of a control lever 118, which is moved by a second drive 120. The control lever 116 is pivotally mounted and can be moved via a gear lever 122. The gear lever 122 is pivoted, for example, by a disk that is rotatably driven by the second drive 120. By engaging the control lever 118, the actuating projection 116 and thus the release actuator 112 can be moved in the longitudinal direction in order to move the at least one movable gripping arm 106. For example, the at least one movable gripping arm 106 can be moved into a released position in order to release the holder.

Fig. 8A shows the transmission element 16 in detail with the holder 20 released. Fig. 8B shows the transmission element 16 in a position in which the holder 20 is held by the at least one movable gripping arm 106.

Fig. 9A shows another example of the transmission element 16 in a retracted position. Fig. 9B shows the transmission element from Fig. 9A in an extended position with another example of an alternative release mechanism. As an example, Fig. 9A and Fig. 9B provided that the release actuator is a release lever 140 which is provided on the transmission element 16 and is movable by a fixed stop 142 in order to release the mandrel 102. The release lever 140 bears against the stop when the transmission element 16 is in the extended position. By bearing against it, the release lever 140 causes a longitudinal movement of the rod, ie the pin 113, which subsequently moves the at least one movable gripping arm 106, for example in order to release the holder 102; or in order to vary the holding force.

For the longitudinal movement of the rod, the release lever 140 encompasses an area of the rod which is limited by two stops 144, so that a pivoting movement of the release lever 140 causes a translation of the rod.

Fig.10 shows another example of the transmission element 16 in an extended position with an alternative release mechanism. The release actuator is a release lever 160 which is provided on the transmission element 16 and is movable by a movable stop 162 to release the mandrel 102. The movable stop 162 is movable by a separate drive 164 to release the mandrel 102. The movable stop 162 can be engaged with the release lever in an area when the transmission element 16 is extended and/or when it is in the extended position. The release lever 160 causes a longitudinal displacement of the rod, ie the pin 113. With this movement, the hold of the holder 20 at the front end of the transmission element 16 can be adjusted.

The movable stop 162 is formed, for example, by a latch 166 which is held at at least two points by pivotable holders 168 and can perform a rotational-translatory movement. The movable stop 162 can also be referred to as an actuating/switching element. The movement of the movable The stop 162 can be moved, for example, with a worm wheel 172 driven by a motor 170, which has a cam 174 to abut against the movable stop 162 and move it.

Since the movable stop 162 extends over a range in the direction of movement of the transmission element 16, it is possible to continuously adjust, i.e. change, the hold of the holder 20 also in intermediate positions of the transmission element 16.

Fig. 11 shows another example of the transmission element in an extended position with another alternative release mechanism. The release actuator is a release lever 180 which is provided on the transmission element 16 and which is movable from a stop 182 of a plurality of stops 184 to release the mandrel. The plurality of stops 184 are arranged on a movable latch 166 which is movable perpendicular to the extension direction of the transmission element in the direction of the release lever to bring one of the stops into engagement with the release lever to actuate release levers by movement of the transmission element.

The movable bolt is designed like a comb and can be moved upwards or sideways, for example, i.e. in Fig. 11 in the x or z direction. By moving towards the transmission element 16, the comb structure comes into the engagement area of the release lever. The closest stop then comes into engagement with the release lever when the transmission element moves and causes the drive to disengage from the transmission element.

The release lever 180 causes a longitudinal displacement of the rod, i.e. the pin 113. With this movement, the hold of the holder 20 at the front end of the transmission element 16 can be adjusted.

Since the stop consisting of a plurality of stops 184 extends over a range in the direction of movement of the transmission element 16, it is possible to adjust, i.e. change, the hold of the holder 20 even in slightly spaced intermediate positions of the transmission element 16.

According to one example, the holder has a receptacle, or is designed as a receptacle 24, for temporarily holding the extending free end of the Transmission element 16, wherein the free end has a coupling region 25 which is designed to protrude at least partially into the receptacle.

Fig. 12 shows an example of the receptacle 24 for temporarily holding an extending free end of the transmission element 16. Fig. 13 shows the recording from Fig. 12 in different situations with respect to the free end of the transmission element 16.

In the example from Fig. 12 and Fig. 13 it is provided that the coupling area 25 is formed at the free chain end with a widening coupling area 302 and the receptacle 24 has at least two movable holding elements 304 in order to at least partially encompass the coupling area 302 so that a releasable positive connection can be created with respect to the holding direction. The two movable holding elements 304 act on the coupling area 302 with an adjustable force. A first force and a second force can be set with an actuator 306 in order to generate the first holding force and the second holding force. The holding elements 304 can be moved in a release direction with the actuator 306 in order to release the holding force. The first and second forces are designed such that the receptacle 24 releases the coupling area 302 in an overload situation.

Fig. 13 shows picture 24 from Fig.5 in different holding states: In the left illustration, the coupling area 302 is still outside the effective range of the two movable holding elements 304. / In the second illustration, seen from the left, the coupling area 302 is within the effective range of the two movable holding elements 304, which act on the coupling area with the second holding force. In this arrangement, the free end of the chain is held firmly. / In the third illustration, seen from the left, the coupling area 302 is within the effective range of the two movable holding elements 304, but these are only held with the first holding force and the connection can be released, for example to open the vehicle door further by hand. / In the right illustration it is indicated that the coupling area 302 is detaching from the two movable holding elements 304.

In one example, the receptacle 24 is designed to change from the first holding force to the second holding force in the presentation position and to move the vehicle door into a closed position. In a further example, the receptacle 24 is designed to release the second holding force in the closed position.

In one example, the receptacle 24 is configured to change from the released force to the first holding force in the closed position in order to move the vehicle door into the presentation position, i.e., to open it.

For example, the movable holding elements 304 are held spring-loaded in a holding direction in order to provide the first holding force. For the second holding force, a locking of the movable holding elements can be temporarily set by an actuator. The holding elements 304 can be moved with the actuator in a release direction against the first and second force in order to release the holding force.

In another example, the second holding force is provided by a spring load, and the actuator is used to attenuate, i.e., counteract, the second holding force to produce the first holding force.

In one example, the actuator is used instead of or in addition to the spring load to generate the first holding force.

In one example, it is provided that the movable holding elements 304 are designed with a defined elasticity in order to release the coupling area in an overload situation, for example in order to provide anti-pinch protection when tightening. Releasing the coupling area in an overload situation is provided as an option.

Fig. 14 shows a schematic representation of another example of a receptacle for temporarily holding an extending free end of the transmission element. Fig. 15 shows a schematic representation of another example of a receptacle for temporarily holding an extending free end of the transmission element.

Fig. 14 shows the free chain end with a coupling area 308, which is designed to protrude at least partially into the receptacle 24. The receptacle 24 has at least one clamping unit 310 with an actuator 312 in order to hold the coupling area 308 in a clamping manner, so that a releasable frictional connection can be created with respect to the holding direction. At least one movably held A bracing element 314 is provided which can be pressed against the coupling region 308 with an adjustable force. A first force and a second force are adjustable in order to generate the first holding force and the second holding force.

In one example, the actuator presses the bracing element 312 against the coupling area with a spring element 316. The opposite bracing element is, for example, fixed. A first double arrow 311 indicates the adjustment of the movable bracing element 312. A second double arrow 313 indicates the pressing by the spring element 316.

In one example, it is provided that in a holding state the free end of the transmission element with the coupling area projects into a first area 320 of the receptacle and the receptacle has a second area 322 adjacent to the first area into which the coupling area can be moved in an overload situation. The design of the second area as an overload coupling function is provided as an option. The second area can also be referred to as additional installation space. A first arrow 309 indicates the insertion of the coupling area 308 into the first area 320.

An overload in the closing direction of the vehicle door can be made possible by providing additional installation space in the receiving element. This allows the support element to slip in the event of an overload. The second area forms an overload clutch in the closing direction of the vehicle door. In the opening direction, an overload clutch is integrated due to the design-related force-locking connection.

Fig. 14 shows an example in which the clamping unit has at least one clamping element that is held with an eccentric disk 324 that can be adjusted via an actuator 326 to provide different holding forces. The actuator 326 has, for example, a motor that moves the eccentric disk 324 via gear elements, which acts on the spring element 316.
