Description

The invention relates to a door structure for vehicles with the features mentioned in the preamble of claim 1 and according to claim 12 to a door for a vehicle with such a door structure.

It is known that the active and passive safety systems of vehicles are constantly being developed to protect human life in dangerous situations. Among other things, it has been found that in the event of side collisions between vehicles, it is advisable to keep the side doors closed. A door that opens automatically as a result of a side impact poses the risk that the occupant(s) could be thrown out of the vehicle before the kinetic energy of the vehicles involved has dissipated. In this case, a person would be safer accommodated and protected inside the vehicle cell than outside the vehicle between the still moving masses of the vehicles involved.

The existing locking devices of the vehicle doors usually include a lock unit, an operating lever and a transmission element such as a Bowden cable or a rod with which the lock unit and the operating lever are mechanically linked. These mechanical locking devices only close reliably if the door and, if applicable, the vehicle body are in an intact condition, but cannot always keep the door reliably closed after a deformation of the door or the body.

The EN 100 04 161 A1 discloses an adaptive door lock for motor vehicles with a security device that enables or prevents the opening of a vehicle door depending on at least one sensor-detected vehicle environment situation, and is characterized in that the security device comprises the door locking system, an environmental sensor system provided on/in the motor vehicle and monitoring means acting on the door locking system, wherein the environmental sensor system generates signals that are fed to the monitoring means, which control the door locking system in such a way that it keeps the door closed permanently or for a specific or determinable time if they judge from the signals provided by the environmental sensor system that the safety of opening the door is in question due to the vehicle environment situation. This system is very complex and is designed to detect not only a collision but also traffic situations. In addition to high costs, it is therefore questionable whether this proposed system can guarantee reliable door security in the event of a collision.

The EN 10 2005 049 144 A1 discloses a door handle in which a so-called mass lock is installed, which is brought into a locking position in the event of an impact due to its mass inertia. The EN 10 2005 049 142 A1 discloses a door handle in which a so-called mass lock is installed, which is brought into a locking position in the event of an impact due to its mass inertia, the mass lock in this case being arranged together with a Bowden cable. The actuation by the own mass inertia of an additional mass lock device means a dependency on the impact force and, on the other hand, an increase in the weight of the vehicle, which has a detrimental effect on the intended safety function and on the driving characteristics of the vehicle linked to the weight of the vehicle.

The EN 10 2006 029 570 A1 aims to offer an improved actuating device for a vehicle door without solving the problem of a side impact and is therefore to be placed in the technical background of the present invention.

Furthermore, a solution for additionally locking a door in the event of an impact is known in which a rheopexic medium is used as a damping mechanism, which has the property that in the case of slow movements of the handle, such as those caused by a user, the damping mechanism offers a very low damping resistance and in the case of a very fast movement, which occurs in the event of a side impact, the rheopexic medium offers a very high damping resistance, thus maintaining the locking of the door until the impact forces are dissipated. The rheopexic medium is, for example, a hydraulic fluid in a cylinder, which reveals the disadvantages of this solution, being complex and fragile, since a leak in the cylinder can lead to the failure of the security system.

The JP2002-213 131 A1 describes a locking structure of a vehicle door with an actuating rod which is guided between two clamping elements. In the event of a collision, deformation of the outer panel of the vehicle door causes one clamping element to move against the other clamping element, thus clamping the actuating rod and preventing it from moving axially, which would cause the vehicle door to open. The DE 101 14 965 A1 describes a locking device Device on a vehicle door lock with a locking element with several locking surfaces (teeth) which, in the event of an accident-related acceleration of the vehicle or a handle on the vehicle door, moves into a locking position by mass inertia against the force of a spring element. DE 198 28 444 A1 describes a side impact protection system for vehicles in the interior of a vehicle door, with two bolts that are located at the ends of a tube and that, when the vehicle door is closed, retract into the bars on the side of the door and anchor there. When an inner or outer door opener is operated, the bolts are retracted again and release the vehicle door.

With the means described above, it is obviously not possible to reliably secure the door in question against opening in the event of a collision directed at a vehicle door and yet to enable this door to be opened intentionally after the collision both from the inside and from the outside.

In contrast, the GB 2 353 771 A a vehicle door with holding means for keeping the vehicle door closed in the event of a collision, said holding means being bolts which are moved into a locking position by means of spring force or by fluid pressure against a spring force. The latter variant allows the bolt to be returned to its original position by means of spring force through controlled leakage and thus to open the vehicle door after the collision.

The invention is based on the object of ensuring that in the event of a collision directed at a vehicle door, the door in question is reliably secured against opening and yet an intentional opening of this door after the collision is possible both from the inside and from the outside.

The present invention is based on a door structure for vehicles, comprising a door base body with a covering surface forming the outside of the door, a locking/closing device, an actuating lever of the locking/closing device and a first transmission/connecting means connecting the actuating lever and the locking/closing device. The door structure can also have an optional interior locking lever which is connected to the same locking/closing device by means of the first transmission/connecting means or an additional second transmission/connecting means. A lock device can be used as a locking/closing device and a manual interior locking according to one of the known types can be used as an optional interior locking lever. For example, an interior locking mechanism can be missing in a rear door. Furthermore, it is provided that at least one locking actuating means according to the invention is arranged on the inside surface of the cover surface of the door or in its immediate vicinity, which is connected to the locking/closing device in such a way that the locking/closing device is additionally blocked against opening when the locking actuating means is actuated. According to the invention, the locking actuating means is linked to the locking/closing device via an additional third transmission/connecting means in such a way that the locking/closing device is additionally blocked against opening when the locking actuating means is actuated, that the additional third transmission/connecting means is fastened to at least one holder element positioned inside the door body at a distance from the surface of the cover surface of the door on the inside of the door, that a tensioning means is arranged between the holder element and a pressure-absorbing section of the locking actuating means in such a way that the additional third transmission/connecting means is clamped, and that the tensioning means has a pre-tensioning force which is sufficient to push back the cover surface which has been pressed in after an impact, so that the locking or closing device is released again.

As a result, the first and/or second transmission/connection means used in normal daily use can remain unclamped by the locking actuating means as in a previously described embodiment. This offers the advantage that these first and/or second transmission/connection means used in normal daily use remain unaffected by the measures according to the invention and can therefore retain their intended normal function in the event of a defect in the means or measures according to the invention. Furthermore, the mechanical movement acting on this additional third transmission/connection means in the event of a collision can be passed on as a movement path in order to be able to carry out a more effective active actuation of the locking/closing device. The cover surface of the door, which is usually made of sheet metal, can apply restoring forces in the event of an impact due to its own elasticity. However, the predetermined pre-tensioning force of the tensioning means, preferably a spiral spring, which is designed for tensile or compressive stress, depending on how the transmission/connecting means is designed, ensures that the locking actuating means according to the invention acts in the intended manner to block the door against opening during an impact and is already immediately bar after the impact, the lock automatically deactivates so that an occupant from inside or a person from outside can open the door in the usual way.

According to a preferred embodiment of the present invention, the blocking of the locking/closing device by the locking actuating means is achieved by means of a movement transmitted to the additional third transmission/connecting means, which performs a locking/closing device function in the locking/closing device.

Alternatively, in a further preferred embodiment of the invention, the blocking of the locking/closing device by the locking actuating means can be achieved with the aid of the additional third transmission/connecting means by the locking actuating means coming into firm engagement with the additional third transmission/connecting means. In this case, no movement is transmitted to the locking/closing device, but rather it is only blocked.

A preferred development of the present invention provides that at least one of the first, second or third transmission/connection means is designed as a Bowden cable with a sheath element and a cable guided through the sheath element, wherein the cable is designed for a pulling and/or a pushing effect.

Alternatively, according to a further preferred embodiment of the invention, at least one of the first, second or third transmission/connection means is designed as a rod element, wherein the rod element is designed for a tensile and/or compressive effect.

In a particularly preferred embodiment of the present invention, more than one locking actuating means is arranged within the door base body and is connected to the locking/closing device of the door via a common or separate additional transmission/connection means.

Preferably, the locking/closing device is designed as a lock.

According to a particularly preferred further embodiment of the present invention, the locking actuating means is arranged to act on an additional locking device. As a result, the standard locking/closing device, usually designed as a lock, can either remain completely unaffected or an interaction of both locking/closing devices according to the invention can be achieved.

According to an advantageous embodiment of the present invention, the holder element is arranged on an impact beam located inside the door body or on another section of the door body that is fixed to the door. Such an impact beam can be provided in a vehicle door to absorb lateral impact energy and is then a suitable fastening base.

Preferably, actuation of the locking actuating means is carried out by a deforming mechanical action on the cover surface forming the outside of the door, which corresponds to an impact in a direction substantially perpendicular to the door.

The invention also relates to a door for a vehicle with a door structure according to one of the preferred embodiments described above. This door is preferably a pivotably or displaceably mounted side door, a rear door, a tailgate or a rear lid of a vehicle.

Further preferred embodiments of the invention result from the remaining features mentioned in the subclaims.

Embodiments of the invention:

1 shows a schematic cross-sectional view of a preferred embodiment with an active blocking pressure actuation of the (see 3 ) Locking/closing device 40, which is designed as a lock of a vehicle door.

For this purpose, at least one locking actuating means 33 is arranged directly on the inside surface of the cover surface 18 of the door or in its immediate vicinity, which is connected to the locking/closing device 40 in such a way that the locking/closing device is additionally blocked against opening when the locking actuating means 33 is actuated.

In this embodiment, the locking actuating means 33 has a pressure-absorbing section 32 for absorbing a force 20 deforming the cover surface in the event of an impact, a pressure rod 34 which acts on a Bowden cable 38 designed for pressure action, a holder element 30 and a spiral spring 36 which prestresses the pressure-absorbing section 32 against the inside surface of the cover surface 18 of the door or up to its immediate vicinity.

An example of this is the arrangement of the holder element 30 of the locking actuating means 33 on an impact beam 16 present within the door, although any other fixed section within the cavity 12 of the door can be used for this purpose.

If a force 20, which in the event of a side impact is applied essentially perpendicularly to the cover surface 18 of the door, presses in the cover surface 18, which is usually made of a thin metal sheet, the pressure-absorbing section 32 of the locking actuating means 33 is pressed into a casing element of the Bowden cable 38 held on the holder element 30. A cable 39 of the Bowden cable 38, for example made of a solid metal wire, which is housed in this casing element of the Bowden cable 38 and designed for a pressure effect, transmits the mechanical movement thus generated, for example to the locking/closing device 40, which is preferably designed as a lock (see 3 ) or to an additional locking/closing device not shown in the drawing.

This makes it possible to activate an additional locking/closing device function in a locking/closing device 40, which can help to secure the vehicle door more reliably in the event of an impact.

The coil spring 36 has such a high preload force that it is sufficient to push the cover surface 18 outwards again after a side impact and thereby return the push rod 34 and with it the Bowden cable 38 to their original position. After the Bowden cable 38 has been returned to its original position, the locking/closing device 40 is released again. As a result, the locking actuating means 33 according to the invention acts in the intended manner during an impact to lock the door against opening and immediately after the impact, the locking actuating means 33 according to the invention automatically deactivates itself so that an occupant from the inside or a person from the outside can open the door.

2 shows a schematic cross-sectional view of a preferred embodiment with active blocking actuation as in 1 , but in an advantageous embodiment designed for a pulling effect.

For this purpose, the movement that occurs during the impact is transferred from the pressure-absorbing section 32 to the pressure rod 34, which is connected to a cable 39 designed for a tensile effect. The cable 39 is deflected on a deflection roller 43, whereby a compressive movement is converted into a tensile movement. Using a tensile movement instead of a compressive movement makes it possible to exploit the advantage that the elements subjected to tensile stress can be made much thinner, i.e. with a lighter weight, than the same elements when transmitting the same force through a compressive stress.

In all other details, this solution corresponds to that in 1 shown, with the exception that the additional locking/closing device function in the locking/closing device 40 must also be designed for tensile stress.

Embodiments that are not part of the subject matter of the invention:

3 shows a schematic cross-sectional view of an embodiment with passive blocking actuation in an overall view of the door structure 10.

The door structure 10 has a door, which in turn has: a door base body with a covering surface 18 forming the outside of the door, a locking/closing device 40 designed as a lock, an actuating lever 42 of the locking/closing device 40 and a first transmission/connecting means 45 connecting the actuating lever 42 and the locking/closing device 40 with a casing element which is divided into casing elements 44 ₁ and 44 ₂ .

The door assembly preferably includes an optional interior locking lever (not shown) connected to the locking/closing device 40 by means of the same first transmission/connection means 45 or an additional second transmission/connection means (not shown).

The transmission/connecting means 45 is usually designed either as a Bowden cable 38 or as a rod and transmits the manual actuation of the actuating lever 42 by the user to the locking/closing device 40 designed as a lock in order to unlock it for opening the door.

This Bowden cable 38 is guided through a locking actuating means 33 approximately in the middle section of the door. For this purpose, the casing element of the Bowden cable 38 is split into two casing elements 44 ₁ and 44 ₂ so that the cable 39 of the first transmission/connecting means 45 appears between them, on which elements of the locking actuating means 33 can act in the event of an impact.

The two casing elements 44 ₁ and 44 ₂ are each held at their end in a fastening element 46 ₁ and 46 ₂ on a fixed section of the door structure. A clamping means 50 is arranged in a force-fitting manner on the cable pull 39 of the first transmission/connecting means 45 between the fastening elements 46 ₁ and 46 _2. The clamping means 50 is designed in the form of a cam, which is designed, for example, as a disk, which engages in a corresponding slot of a counter-clamping means 48 when the cover surface 18 is deformed in the direction of the force 20 in the event of an impact. At this time, the door is locked and the actuating lever 42 is not actuated, so that the clamping means 50 and the counter-clamping means 48 are arranged opposite one another and can thus be brought into engagement with one another.

During normal operation, the clamping means 50 does not engage the counter-clamping means 48 when the user actuates the actuating lever 42 because the clamping means 50 is arranged at a corresponding distance from the slot of the counter-clamping means 48.

In a preferred further development, the clamping means 50 can be attached to the cable pull 39 with a defined friction force, so that after a collision the door can still be opened by applying an increased opening force to the actuating lever 42 in order to release the occupant(s) from the vehicle.

4 shows a schematic cross-sectional view of a further embodiment according to 3 . In addition to the 3 In the embodiment shown, the counter-clamping means 48 in this embodiment has two counter-clamping means 48 ₁ and 48 ₂ . By engaging the clamping means 50 from two sides in the event of an impact, it is held in place particularly reliably. The remaining functionality corresponds to that of the already described under 3 shown, which is why a repeated description has been omitted at this point.

5 shows a schematic cross-sectional view of a further embodiment. In particular, a special clamping means 50 attached to the cable pull 39 of the first transmission/connection means 45 has been dispensed with and instead a two-part counter-clamping means 48 ₁ and 48 ₂ acts directly on the cable pull 39 of the first transmission/connection means 45 in order to push them, for example with a tooth-shaped counter-clamping means 48 _1, into the toothing of the oppositely arranged second counter-clamping means 48 _2. If the depth of these two toothing elements is configured accordingly, in addition to mere clamping, a pulling effect can also be transmitted to the cable pull 39 of the first transmission/connection means 45, whereby an active actuation similar to that in 1 and 2 described can be achieved.

6 shows a schematic top view of a further embodiment. Deviating from the previously described embodiments, the clamping means 50 is designed as a thin sheet metal part that is firmly connected to the cable pull 39 of the first transmission/connection means 45. The counter-clamping means is designed in the form of at least one, here for example three nail-like pins 51, which are attached for example to the cover surface 18 of the door and in the event of an impact are inserted and pushed through the thin sheet metal of the clamping means 50 by the deformation movement of this cover surface 18. There can be openings provided for this purpose or alternatively there can be no such openings, whereby then the sheet metal part can be pierced by the impact effect.

In this illustration, the force 20 is directed into or out of the drawing plane. The remaining functionality corresponds to that already shown in the previous figures, which is why a repeated description has been omitted at this point.

7 shows a schematic cross-sectional view of a further embodiment.

Here, the clamping means 50 and a one-piece counter-clamping means 48 are designed as interlocking, conically shaped parts with inclined, interlocking retaining surfaces. These inclined retaining surfaces ensure that even in the event of minor positional deviations, which are due to manufacturing tolerances, for example, the corresponding clamping means 50 and counter-clamping means 48 are automatically aligned and positioned in the event of an impact.

8th shows a schematic cross-sectional view of a further embodiment. Here, the counter-clamping means 48 is again in two parts, but designed as two interlocking toothed strips 48 ₁ and 48 ₂ , which can clamp a clamping means 50 attached to the cable pull 39 of the first transmission/connecting means 45 in the event of an impact.

9 shows an additional schematic cross-sectional view of a further embodiment.

In this case, the counter-clamping means is designed in three parts 48 ₁ , 48 ₂ and 48 ₃ and is installed in a conically tapered corrugated fold of the impact beam 16 in such a way that the inclined side surfaces of the corrugated fold serve as sliding surfaces for the wedge-shaped counter-clamping means 48 ₂ and 48 ₃ , which are pressed into the corrugated fold of the impact beam 16 in the event of an impact and, in interaction with the counter-clamping means 48 ₁ arranged opposite, can clamp the cable pull 39 directly without a clamping means attached to it.

10 shows a further schematic cross-sectional view of a further embodiment.

As an alternative to previous designs, a two-part counter-clamping means 48 ₁ and 48 ₂ is arranged on the inside surface of the cover surface 18 of the door. These two counter-clamping means 48 ₁ and 48 ₂ are designed as toothed strips and, in the event of an impact, press directly onto the cable pull 39 of the first transmission/connecting means 45 and together with this onto an opposite surface of an impact beam 16. The double design ensures greater safety and, on the other hand, different sections of a door can be used as sections that carry out the movement, so that, for example, not only a middle door section is used to actuate or block a door lock according to the invention.

11 shows a schematic cross-sectional view of an alternative further embodiment.

In this embodiment, similar to the 1 and 2 shown embodiments, an additional Bowden cable 38 is used (corresponding to the third transmission/connection means in the claims). However, in the event of an impact, as in 1 and 2 does not trigger any active movement, but merely serves to block the door lock (not shown) as in the embodiments according to 3 to 10 described. Therefore, the cable 39 of the first transmission/connection means 45, designed as a Bowden cable 38, ends with an end piece 47. A one-piece counter-clamping means 48 is arranged opposite a surface of the impact beam 16 and is designed as a toothed strip, the teeth of which can clamp the cable 39 in the event of an impact.

12 shows a schematic cross-sectional view of one of the embodiments, in which the embodiment of 11 is further improved in that the cable pull 39 of the first transmission/connecting means 45 designed as a Bowden cable 38 is tensioned with a tensioning means designed as a spiral spring 36 so that the actuation of the locking/closing device 40 designed as a lock can occur as directly as possible without play in the event of an impact.

For this purpose, the Bowden cable 38 including the cable 39 is held in two holder elements 30 ₁ and 30 ₂ and it acts as in 10 described a two-part counter-clamping means 48 ₁ and 48 ₂ on two opposite surfaces of an impact beam 16.

The foregoing statements are merely exemplary and are not to be interpreted as limiting the present invention. The present inventive teaching can easily be transferred to other applications. The description of the embodiment according to the invention is intended for illustration and not to limit the scope of the patent claims. Many alternatives, modifications and variations are apparent to an average person skilled in the art. man, without having to depart from the scope of the present invention, which is defined in the following claims.
