Description

The invention relates to a sliding door device for the side door opening of a passenger vehicle, comprising at least a door and a drive device for moving the door transversely and longitudinally to the longitudinal axis of the passenger vehicle, wherein the sliding door device is designed such that the door is aligned in the closed state with the side wall of the passenger vehicle while the door rests in the open state on the outside of the side wall of the passenger vehicle.

Such Schiebetüreinrichtungen are known, which may for example be designed as a sliding sliding doors, as is typically the case for vehicles for public transport. For example, the DE 2 020 576 Such a pan / sliding door device for a vehicle, wherein the pivoting of the door via parallelogram and the displacement via a telescopic guide above the door opening done.

In the field of passenger cars or in the field of commercial vehicles and minivans Schiebetüereinrichtungen are also known in which a door can be moved by appropriate sliding door guides between a closed and an open position. In this case, three rails are usually used, wherein in the door opening in each case an upper and a lower rail are provided. Further, a middle track and guide rail on the outside of the sidewall is used to guide the door outwardly along the sidewall. An electrification of the door via a drive is usually realized in this middle rail.

However, the middle rail significantly affects the appearance of the vehicle. Further, since this middle rail is exposed to the weather, it must be formed from appropriate materials which disadvantageously increase the manufacturing price of the vehicle. Therefore, there are several approaches in the art for avoiding the middle rail. For example, the EP 1 372 999 B1 a solution in which the middle rail is mounted on the inside of the door.

However, even with a rail on the inside of the door, a drive of the door is not always satisfactory to realize. This usually includes cables, with which the door is moved back and forth, wherein the drive motor for moving the cables is located on the vehicle. It must therefore be made on the cables between the drive motor and the door, which can lead to various problems due to the constant movement of the door. Furthermore, the cables are prone to failure.

From the DE 10 2013 113 483 A1 a Schiebetüereinrichtung with a drive device is known which uses a slotted guide. However, the slide guide has due to the power deflection on a relatively high wear and the door tends to tilt.

The object of the invention is therefore to provide a sliding door device for the side door opening of a motor vehicle, which does not require a central guide rail, the sliding door device is particularly easy to electrify and insensitive to interference. The wear should be low. Furthermore, it is the object of the invention to provide a passenger vehicle with such a sliding door device.

According to the invention, this object is achieved by a sliding door device according to independent claim 1. Advantageous developments of the sliding door device result from the dependent claims 2-10. Furthermore, the object is achieved by a passenger vehicle according to claim 11. It should be noted that the features listed individually in the protection claims can be combined with each other in any technologically meaningful manner and show further embodiments of the invention. The description, in particular in connection with the figures, additionally characterizes and specifies the invention.

Instead of driving the door in the X direction and in the Y direction via a single motor, in which the direction change is ultimately effected via guide rails, two motors are now used according to the invention. Instead of the known sliding guide in this case, the telescopic guide for the displacement of the door in the X direction, ie in the longitudinal direction of the vehicle, via a first motor and a first drive means, such as a toothed belt, a spindle or a rope causes.

The shift in the Y direction, ie transversely to the X direction, then takes place via a second motor and a second drive means. This drives as drive means also a toothed belt, a spindle, a rope or the like, over which a movable support which carries the door and the components, is moved. In principle, two possibilities are conceivable, namely that the second motor is firmly connected to a stationary component on the vehicle or moves along with the movable carrier, thus traveling along with it. In the first variant, the second motor drives, for example, a spindle whose spindle nut is fixedly connected to the movable support, whereby these at Rotation of the spindle is moved in the Y direction. The second motor thus remains stationary in its position. In the second variant, however, the second motor is fixed, for example, with the spindle on the movable support, while the spindle nut is fixedly connected to a stationary on the vehicle component. In this variant, the motor thus also moves in the Y direction.

In both variants, the coordination of Ausschwenk-or. a pivoting movement via position-dependent controls of the two motors.

The sliding door device according to the invention for the side door opening of a passenger vehicle comprises at least one door and a drive device for moving the door transversely and longitudinally to the longitudinal axis of the passenger vehicle. In this case, transverse to the longitudinal axis in the sense of this invention means a movement at an angle of 1-90 ° to the longitudinal axis of the vehicle, while longitudinal to the longitudinal axis means a movement parallel to the longitudinal axis of the vehicle. However, these movements need not be separate from each other, but may also occur simultaneously, so that a door can be moved simultaneously away from the door opening and parallel to the side wall. In this case, the sliding door device is designed such that the door in the closed state is aligned with the side wall of the passenger vehicle, while the door rests in the open state on the outside of the side wall of the passenger vehicle. The drive device of the device can be arranged below or above the door opening of the passenger vehicle and comprises a carrier on which a first runner is slidably mounted along the longitudinal axis of the carrier. As a result of this movement of the first rotor, the displacement of a second rotor relative to the carrier along the longitudinal axis of the carrier can be effected via a transmission. Furthermore, the door is attached to the second runner, which is preferably a non-rotatable connection.

The movement of a runner thus simultaneously causes the movement of the other runner in relation to the first runner, whereby the travel of the door can be increased compared to solutions with only one slidable runner. In one embodiment of the invention, therefore, the travel of the door between the open position and the closed position is greater than the travel of the first traveler along the carrier. For this purpose, the two runners can be designed, for example, as two telescopic running rails, in which the second running rail can be moved within the first running rail. A telescopic guide has the advantage that the guide can be made compact, wherein it can be made compact in particular in relation to the opening width of the door. However, this rotor connection and in particular the described telescopic guide must be synchronized so that the movement of the rails is uniform.

In addition, the carrier according to the invention is slidably mounted relative to the passenger vehicle transversely to the longitudinal axis of the passenger vehicle. This may be an angle in the range of, for example, 80-100 °, but preferably the carrier is displaceable at an angle of about 90 ° to the longitudinal axis of the vehicle. These measures also make it possible to realize a very compact drive device. The drive device does not have to extend over the entire width of the door opening, but may for example be only half as wide. Furthermore, no moving components of the drive device must be accommodated on the vehicle itself, which in turn are in connection with components that move in the opening and closing operation in relation to the vehicle. Rather, all movable components of the drive device can be mounted on the carrier, wherein the carrier is a compact unit with all the components, which is movable in its entirety relative to the vehicle.

According to the invention, the first runner is connected to a driver which is guided within a first guideway which is fixedly located on the passenger vehicle, and on the side of the door opening opposite the drive device there is a second guideway on the vehicle in which a guidance element is guided. which is connected to the door. The guide element within the second guideway may be, for example, a guide roller which is connected via a guide arm fixed to the inside of the door. About the driver and the guide element within the upper and lower guide track, the drive device and thus the associated door can be moved transversely to and along the vehicle longitudinal axis when the guideways are formed accordingly. In particular, the guideways on straight and curved sections. In this case, the guideway of the drive device may also be referred to as the main guide, while the opposite guide is to be referred to as a secondary guide. Since the synchronized guide experiences a different speed when opening and closing the door than the door, different geometries for the upper and lower guideway arise. It is essential that this guide only serves a quieter running of the door, a power deflection of the drive energy does not take place. Ultimately, this type of slide control can be completely dispensed with.

The transmission between the two rotors can be realized in different ways. For example, a first toothed rack stationary relative to the first runner and at least one first toothed wheel mounted on the first runner and in meshing engagement with the first toothed rack may be provided. The rotational movement of the gear then causes a relative movement of the second rotor and thus the door. To achieve reliable operation, the transmission preferably comprises a second rack mounted on the door leaf, in meshing engagement with the first gear or a second gear meshing with the first gear.

The carrier can be displaceable by means of a linear guide transversely to the motor vehicle longitudinal axis. For example, the carrier may have two lateral rails, which are guided in two guides which are fixedly connected to the motor vehicle, wherein the rails on the carrier and the guides on the motor vehicle extend transversely to the vehicle longitudinal axis. On the rails rollers may be mounted, which roll with a movement of the rails within the guides.

In one embodiment of the invention, the carrier is also rotatably mounted about an axis on the linear guide, which runs parallel to the longitudinal axis of the carrier. The carrier is then rotatable, for example via bolts relative to the lateral rails. This storage compensates for positional tolerances and resulting deviations between the upper and the lower guide.

In a preferred embodiment of the invention, the drive device is mounted below the door opening, i. in the sill area. In this case, it can be provided in particular that the drive device is introduced into a sill of the motor vehicle. The extending carrier can then be used as a step, for example.

Overall, so are, if any, a maximum of only two guide rails above and below the side door opening of a passenger vehicle required, while can be dispensed with a central guide rail. This has the advantage that the design of the side wall of the vehicle can be made simpler, which in addition to technical advantages also brings cost advantages. Furthermore, the sliding door device is easier to electrify. On the one hand, no cables are required, which are exposed to the weather. Furthermore, the drive device moves together with the door, so that no fault-prone connection between drive and door is present.

The invention further comprises a passenger vehicle, comprising at least one door opening and a sliding door device with a door, wherein the sliding door device is designed so that the door is in the closed state aligned with the side wall of the motor vehicle, while the door in the open state on the outside of the side wall of the motor vehicle is applied. According to the sliding door device is designed according to one or more of the described embodiments. The motor vehicle is, for example, a van, van, minivan or minibus.

Further advantages, features and expedient developments of the invention will become apparent from the dependent claims and the following description of preferred embodiments with reference to the drawings.

The schematic representation of an embodiment of the sliding door device according to the invention in 1 shows the sliding door 10 of a passenger vehicle when it is closed. In this case, the motor vehicle and the door opening which closes the sliding door, not shown. The vehicle may in particular be a commercial vehicle, a minivan or a minibus with a sliding side door. From the vehicle are only an upper track 61 and a lower guideway 51 shown in respective fixed to the vehicle guide plates 50 and 60 are introduced. At the guide plates 50 . 60 it may be separate components that are suitably attached to the vehicle. This can be done for example via a screw or other suitable means. The guideways 51 . 61 However, they can also be introduced directly into sheets of the vehicle, so that no attachment of additional guide plates is required.

The upper and lower guideway 61 . 51 is located above and below the door opening, not shown. In the upper guideway 61 is a leader 12 led, as they the enlarged view of the 2 can be seen. This leadership 12 is on a guide arm 11 mounted, preferably rotatably with the inside of the door 10 connected is. The guideway 61 has a straight section and a curved end section. The curvature runs in the direction of the vehicle interior, causing the door 10 is guided on a trajectory when opening the door 10 first away from the door opening and then along the outside of the vehicle. The lower guideway 51 also has such an end curved course, the geometries of the two guideways 51 . 61 but not identical.

Below the door opening, not shown, a drive device is provided, with which the door is manually or electrically driven between closed and open states movable. 1 shows a manually operated drive device 40 , The drive device 40 essentially comprises a carrier 20 , which is mounted transversely displaceable relative to the longitudinal axis of the motor vehicle on the vehicle. This is done in the illustrated embodiment, for example, two rails 22 and 23 , which laterally on the carrier 20 are attached. The rails 22 . 23 include roles in guides 70 and 71 run, which are firmly attached to the vehicle. So are the entire carrier 20 and all associated components movable transversely to the longitudinal axis of the vehicle. Here is the carrier 20 preferably rotatable between the rails 22 . 23 stored, which for example about bolts 21 can be done.

On the carrier 20 is a first runner 30 attached, opposite the carrier 20 along the longitudinal axis of the carrier 20 is displaceable. This displacement takes place substantially parallel to the longitudinal axis of the vehicle, but can also be slightly offset from this, depending on the configuration of the door. The shift can for example take place in that the first runner 30 designed as a rail with a C-shaped cross-section, the one on the carrier 20 firmly attached rail surrounds. Preferably, the runner 30 it is designed as a kind of T-profile, so that on the other side the second buyer 31 can embrace. this is the 4 to see which the drive device 40 in the extended situation shows. One side of the track 30 surrounds a receiving rail 32 on the carrier 20 while the other side is the second track 31 embraces.

With the first runner 30 , which can therefore also be referred to as a running track, is a driver 26 connected within the lower guideway 51 is guided. A movement of the driver 26 within the guideway 51 thus causes a corresponding movement of the track 30 and vice versa. The driver 26 may also be guided via a guide roller in the guideway.

3 clarifies this arrangement again in another view, in which the course of the lower track 51 It can be seen within the driver 26 located. It can also be seen that within the first track 30 the second track 31 is arranged. This second track 31 is displaceable within the first track 30 stored, being in 3 to the left from the first track 30 is extended. In 3 is the door 10 but in the closed state, in which the second track 31 preferably completely or at least very far in the first track 30 retracted. In this state is the driver 26 at the end of the curved section of the guideway 51 and the carrier 20 is over the rails 22 . 23 in the guides 70 . 71 moved so far toward the vehicle interior that the door 10 completely closes the door opening and aligns with the side wall of the vehicle.

4 shows the sliding door device, however, in the open state of the door 10 , The opening was made manually by unlocking the door and then sliding it out of the door opening and along the sidewall of the vehicle. The door 10 is doing the second runner 31 attached, and the second runner 31 is completely out of the first runner 30 moved out. The driver 26 located at the end of the straight section of the lower track 51 , With it the door 10 reached this end position, caused the manual movement of the door 10 through the curvature of the lower guideway 51 simultaneously a shift of the carrier 20 transverse to the vehicle longitudinal axis and a displacement parallel to the vehicle longitudinal axis. This was the door 10 only out of the door opening and then moved along the outside of the side wall of the motor vehicle.

In the case of manual closing, the movement is reversed, so that the door 10 is only moved parallel to the vehicle longitudinal axis along the side wall when the driver 26 through the straight part of the lower track 51 to be led. Once the driver 26 the curved part of the guideway 51 has reached, There is also a movement transverse to the vehicle longitudinal axis in the door opening into it, until the door 10 in the closed state is aligned with the side wall of the vehicle.

The second runner 31 and the first runner 30 are coupled together via a gear so that a movement of a runner simultaneously causes a movement of the other runner. A shift of the door 10 and thus the attached second runner 31 thus simultaneously causes a synchronized movement of the first runner 30 in the same direction. The transmission is not shown in detail in the figures, but can be realized in a suitable manner. For example, a made of plastic gear can be provided to keep the noise low. For this purpose, a gear is provided at the connection between the first and second runners, which in one on the carrier 20 rigidly mounted toothed rack meshes. At the same time, the gear is in meshing engagement with a second rack mounted on the door to prevent the relative movement of the first traveler 30 driven, this rotational movement in a translational movement of the rack and thus the door leaf relative to the first runner 30 convert. The predetermined in the normal case by the longitudinal extent of the drive device and limited by the door opening travel distance of the door is thus increased by. For example, at least a doubling of the travel distance of the first runner 30 be achieved. By an inventively encompassed and possibly other transmission design, including multi-stage, other conditions are conceivable.

5 shows a drive device according to 3 in an electrified embodiment. It is in this drive device 40 ' for example, an electric motor 24 on the carrier 20 appropriate. This electric motor 24 drives a circulating toothed belt 25 on, with the driver 26 connected is. The timing belt is a holder 27 led, which also on the carrier 20 is appropriate. In this way, the driver can 26 between this bracket 27 and the electric motor 24 are moved back and forth, so that too with the driver 26 connected first runners 30 is movable along the carrier. However, it can also be any other type of suitable drive or a power transmission between an electric motor 24 and the driver 26 to get voted.

Through the end curvature of the lower guideway 51 and the Querverschieblichkeit the entire drive device 40 ' within the guides 70, 71 causes movement of the driver 26 along the toothed belt 26 at the same time also a movement of the drive device 40 ' transverse to the vehicle's longitudinal axis when the driver 26 through the curved part of the guideway 51 moved, ie at the beginning of the opening process and at the end of the closing process.

Also here is the driver 26 in connection with the first runner 30 , so that a driven movement of the first runner 30 through the electric motor 24 synchronously the second runner 31 from the first runner 30 moves out. Because the door 10 on the second runner 31 is attached, thus multiplying the track, by the movement of the driver 26 is reachable. The second runner moves 31 always about as far in the first runner 30 into or out of this, as the first runner 30 in relation to the carrier 20 has moved and vice versa. The door 10 So not only can be moved around the way, the distance between the holder 27 and the electric motor 24 corresponds, but depending on the design of the transmission between the first and the second runner, the travel can be at least doubled.

Of the 5 it can also be seen that the entire drive device 40 ' inside the side guides 70 and 71 was moved to the outside. It can also be seen that the geometries of the two guideways 51 and 61 not be identical. In particular, the straight part is the upper guideway 61 longer than the straight section of the lower track 51 because of the travel of the driver 26 due to the telescopic guide shorter than the travel of the upper guide roller 12 is.

The 6 and 7 show a particularly preferred embodiment of a drive for a sliding door device according to the invention. A first engine 80 causes a movement of the first runner 30 and thus the second runner 31 and the door 10 in the X direction and a second motor 82 a movement of the door 10 in the Y direction. The first engine 80 drives in the embodiment shown a toothed belt 84 which then in turn shifts the attached door ten.

The second engine 82 is fixed in the embodiment shown on a component stationary on the vehicle and drives in the embodiment shown as a drive means a spindle 86 at. A spindle nut 88 is fixed to the mobile carrier 20 connected, causing these with the carrier along the spindle 86 is displaceable.
