Stand for a motor vehicle

The invention relates to a positioning device for a motor vehicle, in particular a motor vehicle door, having an electric drive and an adjusting means, the adjusting means being adjustable by means of the drive, and wherein the motor vehicle door can be set up with means of the adjusting means.

Today's motor vehicles are increasingly being provided with convenience functions. For example, in order to make it easier to get into a motor vehicle and to be able to influence the aesthetic as well as aerodynamic shape, motor vehicles are equipped, for example, without an outer door handle. It is also conceivable, however, that an outside door handle is provided, but that this only forwards a switching signal to the motor vehicle door lock to open the door. So-called Aufstellvorrichtun conditions or door openers or door openers are used to facilitate entry, to automate it and, for example, to enable entry into vehicles without outside door handles.

In a known door opener or a correspondingly configured installation device for a motor vehicle door, as has become known from DE 198 35 994 A1, a spindle drive is used. The spindle drive or the ejector device is activated by unlocking an associated door lock on a flap and in particular a tailgate. With the help of Aufwerfereinrich device, the flap is pivoted and a gap is formed, which is assigned a first opening position of the door.

DE 10 2016 105 760 A1 discloses an installation device for a motor vehicle door with a base plate, furthermore with a drive element mounted on the base plate with a drive, a first sensor assigned to the drive element being provided, which is at least between an installation process and a nem manual opening process. The Aufstellvorrich device comprises a drive that can be driven via a sensor and a control unit. A flexible connecting means then enables pivoting of a transmission lever, which in turn enables an erecting movement via a drive lever and a drive slide. To enable the door to be moved or the door to be opened, the drive slide moves linearly and, for example, out of an opening in a body so that an unlocked and unlocked door can be opened at least in some areas. The end position of the drive slide can be detected by means of a second stationary sensor, so that the drive can again be switched off.

From DE 10 2017 124 282 A1 an installation device is known, where an adjusting means can be moved by means of an electric drive and a gear unit. The actuating means can, for example, be present in an opening of a vehicle body, and is for example in contact with the door to be opened. If the operator sends a signal to the motor vehicle that the door is to be opened, the lock is unlocked and unlocked in conjunction with an electric lock so that the actuating means can move the door element into an open position. In the open position, the operator can grasp the door and open it further, i.e. completely.

The devices known from the prior art for setting up a motor vehicle door after unlocking a motor vehicle lock allow the door to be opened at least in some areas so that an operator of the motor vehicle is able to open the door through a gap. The well-known installation devices have basically proven themselves, but always reach their limits when the door is opened in confusing situations, when visibility is poor or at night. This is where the invention comes in.

The object of the invention is to provide an improved positioning device. In addition, it is an object of the invention to provide a positioning device which enables the motor vehicle door to be opened safely. It is also a task be the invention to provide a structurally simple and inexpensive solution len.

The object is achieved by the features of the independent patent claim 1. Advantageous embodiments of the invention are specified in the subclaims. It is pointed out that the exemplary embodiments described below are not restrictive; rather, any possible variations of the features described in the description and the subclaims are possible.

According to claim 1, the object of the invention is achieved in that a positioning device for a motor vehicle, in particular a motor vehicle door, is provided, having an electric drive and an adjusting means, the adjusting means being adjustable by means of the drive and the motor vehicle door being adjustable by means of the adjusting means is, and wherein the actuating means has at least one display means. The construction of the installation device according to the invention now creates the possibility of enabling the door element to be set up safely. If the door element is set up by means of the setting-up device, the door comes into an open position in which the operator can grasp the door element. If the door element is now opened when visibility is poor, a warning can be given to the traffic involved by means of the display means on the control element. By means of the display means it is thus apparent to the road users that a movement of a component arranged movably on the motor vehicle is taking place here. The display means is able to pass on a warning signal or a warning to traffic that is preferably arranged at the rear of the motor vehicle. This is particularly advantageous when poor visibility such as fog or darkness makes it difficult for other road users to open the door.

In a preferred embodiment, the display means has at least one lighting means. The arrangement of a light source in the adjusting means enables a Illumination of the door gap as well as an immediate display of the opening movement. The light source can be designed as a colored LED and, for example, shine as a warning color in red. In terms of control technology, it is also conceivable that the lighting means is switched on at intervals so that, for example, a traffic participant can recognize a blinking so that the opening of the door can be indicated visually. Of course, in addition to the color red, other colors are also conceivable, which can vary depending on the vehicle manufacturer and / or the equipment of the vehicle. The light source can illuminate the opened door gap, especially in poor visibility conditions or in the dark, so that a clear and clearly visible warning signal or a clearly visible display indicates that the door has been opened. There can be one light source, but several light sources can also be arranged on the actuating means, for example to increase light intensity or to enable certain areas of the vehicle to be illuminated. So it is also conceivable through the installation means that a white light illuminates the surroundings, for example the floor, next to the vehicle, while a red light as a display and / or warning illuminates the rear area of the motor vehicle. When speaking of backwards in the context of the invention, this means the rear area of the motor vehicle, whereby a road user who is behind the vehicle can look into the opened gap, so that primarily a display is made in the direction behind the vehicle. In addition, a display means in the form of a lighting means can of course also be seen from a front of the motor vehicle or from the side.

An advantageous further embodiment variant also results when the display means can be illuminated by means of at least one light guide element. It is conceivable that a lighting means, such as an LED, is arranged directly in the setting means in order to illuminate the door gap or the raised area of the motor vehicle door. In addition, according to the invention, it is also conceivable that a single lamp is arranged in the actuating means and / or in the drive or in the Aufstellvor direction or the housing of the drive, and a light guide, such as a fiber optic line, is guided into the area of the actuating means is to produce a display in the actuator. This makes it possible, for example, to use a single illuminant, the light from the illuminant being able to be passed on to different areas in the actuating means. This offers structural advantages, but in particular advantages in the electrical contacting of the illuminant, since the actuating means is movably arranged on or in the motor vehicle. By integrating a light guide element and in particular a flexible light guide element, illumination of the door gap or illumination of the actuating means is advantageously possible.

If the display means is arranged in an area of the adjusting means that is visible when the installation device is installed, a further advantageous embodiment variant of the invention results. The display means is preferably used to illuminate the door gap and as an indication for the user of the motor vehicle or the other road users. In addition to the warning or informational character of the display means in the positioning device, the illumination of the positioning movement of the door element is also advantageous for the user of the motor vehicle, since a visual indication is given that the door has been opened. If, for example, a radio remote control is accidentally operated and the door element is set up, the user of the motor vehicle can also see from a distance that the door is ready to be opened completely. The display means is advantageously attached to the actuating means in such a way that the display means, when activated, enables the door gap to be illuminated immediately, for example. For this purpose, the display means can be designed, for example, as a light source and installed in the axial end of the adjusting means. There is thus the possibility of supporting the erecting movement by means of the illuminant immediately at the beginning of the erecting device.

If the display means has at least one reflection means, a further embodiment of the invention results. In addition to the possibility of using a lamp, there is also the possibility of a reflective means, such as, for example, small cylindrical glass bodies that reflect light and are known as reflectors or retroreflectors. Incident light can thus be reflected and used for the can be made visible to other road users. There is thus the possibility of a display device as well as a warning for road users. A reflection means can be used in combination with a light source and offers an inexpensive and structurally simple way to make a safe on the motor vehicle door possible.

If, within the meaning of the invention, a positioning device is spoken of, then whoever preferably uses the positioning device to set up motor vehicle doors. However, it is also conceivable that a cover for a convertible roof or a hood or flap can be set up by means of the set-up device. By means of the display means it is possible in an advantageous manner to display the erecting movement that was initiated by the erecting device. The installation device can thus advantageously be used for components that are movably arranged on the motor vehicle.

Another advantageous embodiment of the invention results when the display means can be arranged at a free end of the adjusting means. The arrangement of the display means at the free end of the adjusting means, that is, at the end which is in engagement with the movable component on the motor vehicle, offers the advantage that the display means is available at the maximum outer end as an indication or warning means. In particular, if the installation position of the Aufstellvorrich device means that the adjusting means itself extends into the open door gap, an effective display of the opening movement of the door is possible. In addition, there is of course the possibility that a display means in the form of a lamp is arranged at the free end of the adjusting means, and that reflection means, such as retroreflectors, are arranged on the movable component, in particular the motor vehicle door, so that an interaction between the lamp and reflector a visibility of the partitioning of the door increases.

In a further advantageous embodiment of the invention, the adjusting means has a sliding or damping element, the display means in the sliding and / or damping element is arranged. The actuating means is preferably driven by means of an electric drive and preferably by means of a transmission connected downstream of the electric drive, as disclosed for example in DE 10 2017 124 282 A1, and generates a relative movement between the movable component and the motor vehicle body. In order to enable a quiet and safe movement of the motor vehicle door, a damping element can be arranged at the axial end of the Stellmit means. The damping element is preferably made of plastic. Advantageously, the display means can be integrated into the damping element or be formed in one piece with the damping means. The adjusting means can also have a sliding element at its radial end, a sensor, for example, being actuatable by means of the sliding element so that actuation of the adjusting means can be detected in interaction with the movable component. According to the invention, it is also conceivable that the lighting means or the light guide element is integrated into the sliding element. In an advantageous manner, the sliding element can also control the display means when, for example, the display means is designed as a light source.

Furthermore, as a preferred embodiment, it is possible according to the invention that two or more display means can be arranged in the adjusting element. As already described above, for example a light source can be combined with a reflector, or two, three or more light sources can be arranged in different areas of the adjusting means in order to achieve optimized illumination by means of the adjusting means. A combination of two or more display means in the actuating element or on the actuating element can thus increase the visibility of the door opening.

If the display means is in the form of a symbol and / or an alphanumeric character, a further variant embodiment of the invention results. The formation of the display means as a symbol and / or sign enables a function of the installation device to be made immediately visible. Especially in the case in which the adjusting element is directly visible in an end position, for example if the door gap is open, a symbol can, for example, indicate that the door is open. For example, symbols as exclamation marks, a warning triangle and / or a brand symbol of the vehicle manufacturer are conceivable.

A further embodiment results when the display means can be displayed in different colors. If a door gap is illuminated by means of the display means, a warning can be given on the one hand by means of an individual color scheme and on the other hand it is easier to get in or grasp the door element. A flashing of the display means, for example a lamp in different colors, can increase the visibility of the opened door and serve as a warning or as a safety notice. In particular, if the actuating means, for example, opens the door and a gust of wind gets into the door gap, so that the door may open automatically, a different color scheme as a warning can also warn road users, for example by means of a corresponding symbol. Further safety features can thus also be implemented in the motor vehicle for the operator.

The invention is explained in more detail below with reference to the accompanying drawings using a preferred exemplary embodiment. However, the principle applies that the exemplary embodiment does not limit the invention, but merely represents an advantageous embodiment. The features shown can be implemented individually or in combination with further features of the description as well as the claims individually or in combination.

The Aufstellvor device 2 is shown in the retracted state, in which the motor vehicle door 4 with an outer door panel 5 is flush with the body 6. Circumferentially between the motor vehicle door 4 and body 6 there is a door gap 7. In other words, the motor vehicle door 4 is reproduced ben in a closed position.

The erection device 2 has an electric motor 8 as an electric drive 8, which cooperates with a transmission, not shown and only mentioned as an example. The adjusting element 9 is shown in the retracted state and can be exaggerated via the transmission, for example in the sense of a rack and pinion drive. Alternative drive methods based, for example, on frictional engagement are of course also conceivable. A free end 10 of the actuating element 9 protrudes at least in regions from an opening 11 of the B-pillar 3, with three display means 12 being arranged at the free end 10 of the Stellele element 9 in this exemplary embodiment. The display means 12, 13, 14 are designed as lighting means and are arranged symmetrically at the free end 10 of the actuating element 9 merely by way of example.

A control and / or regulating unit 15 arranged in the setting-up device 2 can be connected to a motor vehicle door lock 17 via a vehicle control 16, so that controlled opening or setting-up is electrically supported and independently possible. If, for example, an electronic signal is given to the motor vehicle door lock 17 and / or the control 16 and / or the control and regulating unit 15 of the installation device by means of a radio remote control, then ok

the motor vehicle door 4 can be set up independently. The motor vehicle door lock 17 is electrically unlocked and unlocked by the control signal of the operator of the motor vehicle 1, so that the motor vehicle door 4 is released from a lock holder engaged with the motor vehicle door lock 17. The motor vehicle door 4, which is now freely pivotable, can now be opened or set up by means of the actuating element 9.
