Description

[0001] The present invention relates to a hinge arrangement for a motor vehicle door, in particular for a wing door, of a motor vehicle, according to the preamble of claim 1. The invention also relates to a motor vehicle having a body and a motor vehicle door connected thereto via such a hinge arrangement.

[0002] DE 103 38 776 A1 discloses a generic hinge assembly for a motor vehicle door. It has detachably attached hinge pins for detaching the door hinge from the vehicle door or the body in the event of an accident. If necessary, the hinge pin is pushed out of the hinge by a device. This allows the entire vehicle door to be released in the event of an accident in which the vehicle ends up on its roof, which is particularly important for occupant rescue in the case of wing doors.

[0003] CN 207955286 U discloses a wing door of a motor vehicle that is attached to a vehicle body via a door hinge. A quick-release pin, which is pulled out of a corresponding opening, allows the wing door to be released from the vehicle relatively quickly if necessary, particularly in the event of a crash.

[0004] DE 10 2007 048 446 A1 discloses a pivoting device by means of which a vehicle door, in particular a wing door, is normally mounted on the body of a motor vehicle and pivots between an open position and a closed position. The pivoting device has a separating device by means of which the vehicle door can be released from the body in an emergency, in particular after a rollover.

[0005] DE 10 2013 006 603 A1 discloses a door hinge for a vehicle door, comprising a first hinge part, one end of which is fixed to the vehicle door, and a second hinge part, the other end of which is pivotally mounted on a body part of the motor vehicle that supports the vehicle door. The first or second hinge part is formed in two parts, wherein the two parts of the two-part first or second hinge part are firmly connected to one another by means of at least one connecting screw, and wherein the screw connection created by the at least one connecting screw can be released by means of a sensor-controlled actuator following a crash or other accident. This is intended to enable vehicle occupants to exit the vehicle as quickly as possible, particularly in the event of a crash when the vehicle is lying on its roof.

[0006] DE 10 2008 003 994 A1 discloses a pivoting device for a vehicle door, in particular a wing door. This pivoting device also has a separating device by means of which the vehicle door can be released from the body in an emergency, particularly after a rollover.

[0007] DE 198 53 821 B4 discloses a motor vehicle with at least one wing door mounted on a vehicle roof so that it can pivot about a horizontal pivot axis. The wing door is formed from a roof section and a side section, with the roof section being pivotally mounted on the vehicle roof and the side section being attached to the roof section in such a way that pivotal adjustments of the side section relative to the roof section about a horizontal pivot axis are possible. This is intended to reduce the space required for opening and closing the wing door.

[0008] DE 10 2017 129 248 A1 discloses a device for separating a vehicle door from a body of a motor vehicle.

[0009] DE 330 46 601 A1 discloses a motor vehicle with doors provided on the sides and extending into a roof. These doors consist of a roof section and a side section which are pivotally connected to one another about a pivot connection in the region of the transition to the roof. This pivot connection is lockable. During normal operation, the roof section and the side section are firmly locked to one another, so that the vehicle door functions like a conventional wing door. By means of an anti-roll switch, when a motor vehicle is lying on its roof, the pivot connection between the side section and the roof section is unlocked after a predetermined period of time and upon simultaneous actuation of a door handle, thus making it easier for a passenger to exit the vehicle.

[0010] A disadvantage of prior art motor vehicles and hinge arrangements is that, until now, gullwing doors, in particular, were bolted directly to the body using so-called separating screws. These separating screws thus normally secured the gullwing doors to the body. In the event of a crash, these separating screws connecting the gullwing doors to the body must be loosened, which is why they are not designed to be particularly strong. This, in turn, has the disadvantage that in other crash scenarios, where the separating screws should not be loosened, the potential load transfer via these separating screws is reduced.

[0011] The present invention therefore addresses the problem of providing an improved or at least an alternative embodiment for a hinge arrangement of the generic type, by means of which in particular the disadvantages known from the prior art can be overcome.

[0012] This problem is solved according to the invention by the subject matter of independent claim 1. Advantageous embodiments are the subject matter of the dependent claims.

[0013] The present invention is based on the general idea of ​​securing a motor vehicle door, in particular a so-called upwardly opening wing door, to the body of the motor vehicle not via specially designed separating screws, but via corresponding pins provided in or on a mounting plate. Thus, the hinge assembly according to the invention provides a comparatively stable screw connection of the mounting plate of the hinge assembly to the body, and a crash-related release of the vehicle door is achieved by actuating at least one pin that secures a first part of the hinge assembly to the mounting plate.The screws fastening the mounting plate to the body, for example a steel body or a monocoque, can thus be made significantly stronger and more rigid, which means that in other crash scenarios they can absorb significantly higher loads than was the case with the separating screws previously used to connect gull-wing doors. The hinge arrangement according to the invention for a motor vehicle door, in particular for the aforementioned gull-wing door, of the motor vehicle has a first part and a second part that can be rotated or pivoted about an axis above it. At least one opening, in particular a through opening or an insertion opening, is arranged on the first part. Furthermore, a mounting plate is provided, in or on which at least one actuating device with an adjustable pin is arranged. This pin engages in an associated opening on the first part and thereby fixes the first part to the mounting plate.This represents the normal case. It is further provided that the actuating device is designed in such a way that in a predefined case, i.e. for example in the event of a vehicle rollover in which the motor vehicle comes to rest on its roof, it pushes or pulls the pin out of the opening and thereby detaches the first part of the hinge arrangement from the mounting plate and thereby further detaches the motor vehicle door from the motor vehicle. The great advantage of this embodiment according to the invention is therefore that a comparatively stable and firm screw connection of the mounting plate to the body of the motor vehicle takes place and in or on the mounting plate, the connection of the hinge arrangement and above it the motor vehicle door, which can be detached in the event of a crash, is realized. This makes it possible for the entire hinge arrangement to absorb more load in the event of a crash and still be able to detach in a predefined emergency, ieFor example, in the case of a motor vehicle lying on its roof, the motor vehicle door can be detached from the motor vehicle by simply pushing the pins out of the opening of the first part of the hinge arrangement.

[0014] In an advantageous development of the hinge assembly according to the invention, a recess is arranged on the mounting plate, into which the first part of the hinge assembly engages with its at least one opening. By arranging the mounting plate in the recess, a surface-flush arrangement of the mounting plate can be achieved, whereby, in particular, an outer contour of the motor vehicle is not changed or only marginally changed. Embossing the mounting plate into the body or a monocoque of the motor vehicle is also conceivable. Alternatively, it is of course also conceivable for the mounting plate to be placed on the body and covered, for example, by the motor vehicle door.What all designs have in common is that the mounting plate can be connected to the body with comparatively strong and, for example, thick screws, so that less load-bearing separating screws do not have to be used as before and the connection of the hinge arrangement of a motor vehicle can absorb significantly more load in normal conditions and in other crash situations.

[0015] In a further advantageous embodiment of the hinge arrangement according to the invention, the actuating device has an electric actuator for pulling or pushing out the at least one pin from the associated opening in the first part of the hinge arrangement. By means of such an electric actuator, the pin can be pulled or pushed out of the associated opening in a both cost-effective and comparatively quick manner, and thus the motor vehicle door can be released from the motor vehicle relatively quickly. For example, it is conceivable that the electric actuator is integrated into the mounting plate. In particular, it is conceivable that the mounting plate has a recess accessible from the rear, in which the electric actuator is arranged, so that the electric actuator is protected by the mounting plate when installed.In addition, such an electric actuator offers the great advantage that it can be reused after a vehicle crash in which it has pushed or pulled out a corresponding pin from a corresponding opening.

[0016] In an alternative and advantageous development of the hinge assembly according to the invention, the actuating device comprises a pyrotechnic actuator for pulling or pushing out the at least one pin from the associated opening. The advantage of such a pyrotechnic actuator lies in the comparatively short triggering time, which is particularly advantageous in the event of a vehicle crash. Furthermore, such propellant charges or pyrotechnic actuators are comparatively inexpensive to manufacture compared to electric actuators.

[0017] The first part of the hinge assembly is expediently designed as a hinge base, and the second part as a hinge arm. The hinge base sits within the at least one opening through which, in the normal state, the pin of the actuating device passes, thereby securing the hinge base and thus also the motor vehicle door to the body. The motor vehicle door is connected to the hinge assembly via the second part, designed as a hinge arm. It is of course conceivable that the hinge assembly according to the invention could also comprise two hinge arms or two hinge bases, between which an associated hinge base or hinge arm is arranged.

[0018] The present invention is further based on the general idea of ​​specifying a motor vehicle with a body, for example a monocoque, and a motor vehicle door, in particular a wing door, connected thereto via a hinge arrangement according to the previous paragraphs. This allows the advantages listed with regard to the hinge arrangement to be transferred to the motor vehicle. Specifically, these advantages lie in a comparatively firm connection of the hinge arrangement and thus also of the motor vehicle door to the body of the motor vehicle, since the hinge arrangement is not connected directly to the body of the motor vehicle, but indirectly via the previously described mounting plate. The first part of the hinge arrangement is fixed to the mounting plate via a pin that can be moved in the event of a crash, while the mounting plate itself is connected to the body via several comparatively firm screws.This eliminates the need for separating screws that previously connected the first part of the hinge assembly directly to the body of the vehicle and were less capable of absorbing loads.

[0019] In an advantageous development of the motor vehicle according to the invention, the mounting plate of the hinge assembly is screwed to the body. Relatively strong screws can be used for this purpose, enabling a reliable, extremely stable, and load-bearing connection.

[0020] In a particularly preferred embodiment of the solution according to the invention, the mounting plate of the hinge assembly is arranged in a recess in the body. Alternatively, a surface-mounted arrangement is also conceivable, with a recessed arrangement in particular offering a visual advantage.

[0021] In a further advantageous embodiment of the motor vehicle according to the invention, it has a so-called rollover sensor, which is designed to actuate the actuating device if the rollover sensor detects that the motor vehicle is on its roof. Using such a rollover sensor, emergency exit from a motor vehicle lying on its roof can be significantly simplified, since the rollover sensor detects that the motor vehicle is lying on the roof and subsequently actuates the actuating device, whereupon the latter pulls or pushes out the corresponding pin from the corresponding opening, thereby releasing the motor vehicle door from the motor vehicle.

[0022] Further important features and advantages of the invention emerge from the subclaims, from the drawings and from the associated description of the figures based on the drawings.

[0023] It is understood that the features mentioned above and those to be explained below can be used not only in the respective combinations specified, but also in other combinations or on their own, without departing from the scope of the invention. Components mentioned above and those to be mentioned below of a higher-level unit, such as a device, a device, or an arrangement, which are designated separately, may form separate parts or components of this unit or be integral areas or sections of this unit, even if this is shown differently in the drawings.

[0024] Preferred embodiments of the invention are illustrated in the drawings and are explained in more detail in the following description, wherein the same reference numerals refer to the same or similar or functionally identical components.

[0025] They show, schematically, Fig. 1 a sectional view through a hinge arrangement according to the invention of a motor vehicle according to the invention in the area of ​​a mounting plate, Fig. 2 a side view of a hinge arrangement according to the invention on a motor vehicle according to the invention, Fig. 3 a motor vehicle according to the invention in a side view, Fig. 4 a detailed view of an actuating device.

[0026] According to the Fig. 1 shows a hinge arrangement 1 according to the invention for a motor vehicle door 2 (see Fig. 3), in particular for a so-called hinged door, a first part 3 and a second part 5 connected thereto via an axis 4 so as to be rotatable or pivotable. The first part 3 has at least one opening 14, here two openings 14 corresponding to the Fig. 1. Furthermore, the hinge arrangement 1 according to the invention has a mounting plate 6, in or on which at least one actuating device 8 (cf. also Fig. 4) is provided with an adjustable pin 7, which normally engages in a corresponding opening 14 and thereby fixes the first part 3 to the mounting plate 6.

[0027] In a predefined case, for example in the event of a crash, the actuating device 8 can push or pull the pin 7 out of the opening 4 and thereby release the first part 3 of the hinge arrangement 1 from the mounting plate 6 and thus also the motor vehicle door 2 from a motor vehicle 9 or its body 10.

[0028] Due to the fact that the hinge arrangement 1 can be connected to the body 10 of the motor vehicle 2 via the mounting plate 6, comparatively strong screws 11 can be used to fix the mounting plate 6 to the body 10, since the release of the motor vehicle door 2 from the motor vehicle 9 now takes place for the first time by adjusting the pin 7.

[0029] A recess 12 can be arranged on the mounting plate 6, into which the first part 3 of the hinge arrangement 1 engages with its at least one opening 14. According to the Fig. 1, the first part 3, which can also be designed as a hinge foot, has two openings 14, so that in or on the mounting plate 6 two associated actuating devices 8 with two movable pins 7 are provided, which normally engage in the respectively associated opening 14 and thereby fix the hinge arrangement 1 and the motor vehicle door 2 to the motor vehicle 9 and in the event of a crash, in particular if the motor vehicle 9 is lying on its roof, is pushed or pulled out of the associated opening 14 by means of the associated actuating device 8 and thereby enables the first part 3 to be released from the mounting plate 6.The first part 3 of the hinge arrangement 1 according to the invention is thus fixed to the mounting plate 6 exclusively via the pins 7 of the actuating device 8 and not, as previously, via so-called separating screws, which had to be severed in the event of a crash and could therefore be designed to be significantly less stable in terms of their strength than is possible with screws 11 arranged separately for this purpose, via which only the mounting plate 6 is fixed to the body 10 of the motor vehicle 9.

[0030] By arranging the first part 3 in the corresponding recess 12 on the mounting plate 6, a positive fixing of the first part 3 of the hinge arrangement 1 to the mounting plate 6 and thus to the motor vehicle 9 can also be achieved, which is further fixed by the pins 7 engaging in the openings 14.

[0031] The actuating device 8 can, for example, have an electric actuator 15 for pulling or pushing out the at least one pin 7 from the associated opening 14. Alternatively, a pyrotechnic actuator can also be provided for pulling or pushing out the at least one pin 7 from the associated opening 14. The advantage of an electric actuator 15 lies in its reusability, while a pyrotechnic actuator has advantages in terms of extremely short triggering times.

[0032] As in particular the Fig.As can be clearly seen in Figure 1, the mounting plate 6 of the hinge assembly 1 is screwed to the body 10 of the motor vehicle 9, wherein the mounting plate 6 of the hinge assembly 1 can be placed on the body 9 or arranged in a recess 13 of the body 10. Due to the recessed arrangement of the mounting plate 6 in the recess 13 of the body 10, an almost surface-flush alignment of the mounting plate 6 with the surrounding body 10 can be achieved.

[0033] The motor vehicle door 2 is connected to the hinge arrangement 1 via the second part 5, for example by screwing.

[0034] The motor vehicle 9 may further comprise a rollover sensor (not specified in more detail), which is configured to actuate the actuating device 8 if the rollover sensor detects that the motor vehicle 9 is on its roof. In such a position, the motor vehicle doors 2, which are particularly configured as wing doors, cannot be easily opened, making both exiting the motor vehicle 9 and access to persons still seated in the motor vehicle 9 at least difficult, and in some circumstances even impossible.

[0035] The hinge assembly 1 according to the invention makes it possible for the motor vehicle doors 2 to be released from the motor vehicle 9 if, for example, a corresponding situation occurs, in particular a crash. For this purpose, the hinge assembly 1 according to the invention uses, for the first time, an actuating device 8 whose pin 7 engages in a corresponding opening 14 of the first part 3 of the hinge assembly 1. The actuating device 8 releases the motor vehicle door 2 from the motor vehicle 9 by pulling or pushing the pin 7 out of the corresponding opening 14.

[0036] By eliminating the separating screws previously used for this purpose, a significantly more stable connection of the motor vehicle door 2 to the motor vehicle 9 can be achieved under normal circumstances, whereby this significantly more stable connection is also capable of absorbing higher loads during a crash.
