Description

The present disclosure relates to a holding device, in particular a holding device of a display device of a vehicle, and to a display assembly and a vehicle having the display assembly.Holding devices for holding display devices are known. Adjustable holding devices for adjusting a position and an orientation of display devices are also known. As the number of adjustment possibilities increases, the holding devices become more complex and expensive and more prone to faults.An object of embodiments of the present invention is to provide a robust and cost-effective holding device for a display device, which makes it possible to set the position of the display device in a particularly simple and user-friendly manner.To achieve this object, according to a first aspect, a holding device for a display device in a vehicle is proposed.The holding device comprises a holding element for holding the display device. The retaining element may be configured to retain one or more display devices. In particular, the holding element can be designed to accommodate touch displays, smartphones or electronic display devices such as LED displays. The holding element can in particular also comprise further devices for holding and for fastening, in particular for detachably fastening the display devices. The display device can be designed, for example, as a dashboard display or as a central display of the vehicle.The holding device also comprises a positioning element fixable to the vehicle for positioning the holding element. In particular, the holding element can be designed such that its position is manually and / or electrically adjustable with respect to the positioning element.The holding element further comprises a counter positioning element for coupling the holding element to the positioning element. The counter positioning element is designed such that it can be positioned at different positions with respect to the positioning element. The counter positioning element can be connected to the holding element by a rigid or flexible connection. In particular, the counter-positioning element can be designed such that a translatory movement of the holding element with respect to the positioning element is made possible.The connection between the positioning element and the counter positioning element can be designed such that when a translation or rotation movement is carried out, one of the two positioning elements, the connection, in particular the electrical connection, is not released. By positioning the holding element, the display device held on the holding element can be positioned differently with respect to the positioning element, so that the position of the display device can be flexibly adjusted as required.The counter positioning element can be designed to be able to execute a translatory and / or rotatory movement with respect to the positioning element. Due to the translatory or rotational movement of the counter positioning element, both the position and the spatial orientation of the holding element with respect to the positioning element or with respect to the vehicle can be changed. The counter positioning element can furthermore be configured such that the translatory and / or rotatory movement can be carried out manually and / or electrically. By the corresponding positioning and orientation of the holding element, both the spatial position and the orientation of the display device can thus be set flexibly as required by the user.The holding device can comprise at least one fixing mechanism for fixing, in particular for releasably fixing, the holding element to the positioning element. The fixing mechanism can in principle be any type of fixing mechanism, in particular a fixing mechanism which produces a positive, frictional or frictional connection between the holding element and the positioning element. By means of the fixing mechanism, it can be ensured in particular that the set position or the set orientation of the display device is retained after the setting by the user.The at least one fixing mechanism can comprise at least one spring element, wherein the spring element can be designed to build up a prestress between the positioning element and the counterpositioning element. In particular, the spring element can be designed such that it is already prestressed during the assembly of the holding device. By prestressing the spring element, surface friction between the positioning element and the counterpositioning element can be increased. As a result of the increase in the surface friction, a force-fit connection can occur between the positioning element and the counterpositioning element, as a result of which the current position of the holding element can be fixed.The fixing mechanism may be configured to be released by a manual operation. In particular, the fixing mechanism can be designed such that a manual action, for example pushing or pulling, on the holding element against the spring force of the spring element reduces the surface friction between the positioning element and the counterpositioning element. The display device can thus be adjusted manually by the user in a simple manner with one hand, in that in particular the display device together with the holding element is pressed and at the same time the display device is adjusted.The positioning element or counter positioning element may comprise a rail element or rail and the counter positioning element or positioning element may comprise a compatible rail insert for coupling to the rail element. The rail element can specify in particular a guide track for the rail insert, so that the holding element can be guided along the specified guide track.The rail member may include a slot and the rail insert may include a neck rotatably receivable within the slot of the rail member. By rotating the neck or web of the rail insert, the orientation of the holding element or of the display device can be changed in a simple manner.The neck can have an elongate, in particular a substantially elliptical, cross section, so that the neck can execute a pivoting movement in the slot. The elongated or elliptical cross section of the neck can achieve the effect that the rail insert can execute a rotational movement or rotational movement within defined limits. The boundaries can be defined in particular by the elliptical shape of the neck. It can be ensured in particular that the display device is not rotated too far or is not rotated multiple times about itself in order to avoid overloading of any cable connections which are led through the holding element.In some embodiments, the holding device comprises a receiving device for receiving a base of the display device, wherein the receiving device can be configured to rotatably support the base of the display device. The rotatable mounting of the base of the display device offers a further or additional adjustment possibility or an additional degree of freedom for a flexible adjustment of the display device. In particular, the display device can be adjusted both by the rotation of the counter positioning element with respect to the positioning element and by the rotation or tilting of the base of the display device in the receiving device.According to a second aspect, a display module is proposed. The display assembly includes at least one display device and a holder device according to the first aspect, wherein the display device is held by the holder element of the holder device. The display assembly is characterized by a simple structure and high user-friendliness in the setting of the display device.According to a third aspect, a vehicle is proposed. The vehicle includes at least one display assembly according to the second aspect. By means of the display assembly, a rotatable and displaceable display device can be realized in a particularly compact and cost-effective manner in an interior of the vehicle. Due to the simple adjustability of the display device, the vehicle offers a particularly high user-friendliness and driving safety.The invention will now be explained in more detail with reference to the appended figures. The same reference numerals are used in the figures for the same or identically functioning parts. FIG. 1 shows a display assembly in a schematic cross section according to an exemplary embodiment in a basic state, and FIG. 2 shows a display assembly according to FIG. 1 in a released state, and FIG. 3 shows a schematic cross section in plan view of the holding device according to FIG. 1.FIG. 1 shows a holding device in a schematic cross section according to an exemplary embodiment in a basic state. The display assembly 1 comprises a display device 2 and a holding device 3.The holding device 3 comprises a holding element 4 for holding the display device 2 and a positioning element 5 for positioning the holding element 4. The holding element 4 further comprises a counter positioning element 8 for coupling the holding element 4 to the positioning element 5.The positioning element 5 comprises a rail 9 or a rail element with a slot and the counter positioning element 8 comprises a rail insert 10 with a foot part 11 or lower body part and with a neck 12 fitting into the slot, so that the counter positioning element 8 can be moved or guided along the rail 9. The rail insert 10 with the foot part 11 and with the neck 12 can have, in particular, a T-shaped cross section matching the rail 9. The foot part 11 is located below the rail 9 and is connected to the head part 6 above the rail 9 via the neck 12 of the rail insert 10. The neck 12 extends from the foot part 11 to the head part 6 of the holding element 4.The holding device 3 further comprises a spring element 13. The spring element 13 can be designed in particular as an elastic ring or half-ring made of rubber, which wraps around the neck 12 of the rail insert 10. In the exemplary embodiment shown, the holding device 3 furthermore has a sliding ring 14 with a low surface friction, which is located between the rail 9 and the spring element 13. In particular, the sliding ring 14 can be designed in such a way that a low-friction contact surface 15 is created between the underside of the sliding ring 14 and the upper side of the rail 9. The sliding ring 14 can be designed in particular as a ring or half-ring around the neck 12. The head part 6 further comprises an annular collar 16, wherein the spring element 13 is clamped between the annular collar 16 and the sliding ring 14.The spring element 13 is designed in particular to build up a prestress between the positioning element 5 and the counterpositioning element 8. In particular, the rail 9 is pressed onto the foot part 11 due to the spring force of the spring element 13, so that a contact surface 17 with an increased frictional force is produced between the rail 9 and the foot part 11.In the idle state, the prestress of the spring element 13 thus ensures that the counterpositioning element 8 is fixed on the rail 9 by a frictional connection on the contact surface 17 between the upper side of the foot part 11 and the lower side of the rail 9.As soon as a vertical force is exerted by the user, in particular by pressing on the display device 2 or retaining element 4, the force is transmitted via the collar 16 of the head part 6 of the retaining element 4 to the spring element 13 and the spring element 13 can thereby be compressed more strongly. The pressure force or the frictional force at the contact surface 15 between the sliding ring 14 and the rail 9 increases and the pressure force or the frictional force at the contact surface 17 between the foot part 11 and the rail 9 decreases. Due to the higher friction at the contact surface 17 between the foot part 11 and the rail 9 compared to the friction at the contact surface 15 between the slide ring 14 and the rail 9, the frictional force is reduced overall, so that the counter positioning element 8 can be moved more easily with respect to the positioning element 5. This allows the user to easily move the holding element 4 or adjust the display device 2.In some exemplary embodiments, the surfaces opposite the contact surface 17 have notches or knobs for positioning the holding element 4. The notches can facilitate the adjustment of the display device 2 for the user by defining locking positions of the counter positioning element 8 with respect to the positioning element 5. In addition, they can generate haptic feedback for the user, so that the user can set the display device in a particularly convenient and secure manner.The rail 9 can be designed, for example, to be mounted in a front region of the vehicle interior, in particular on the instrument panel or dashboard. The rail 9 can be oriented along the vehicle longitudinal direction, for example, in the assembled state. The neck 12 can be shaped or dimensioned in particular such that the counter positioning element 8 can execute both a translatory forward-return movement and a rotational or pivoting movement about a central axis 18 of the holding element 4 with respect to the positioning element 5.In the exemplary embodiment shown, the receiving device is formed in the head part 6 of the holding element 4 for rotatably mounting the base 7 of the display device 2. In particular, the receiving device has elastic bearings 19 for eccentrically mounting a shaft 20 of the base 19 of the display device 2 for vertically tilting the display device 2. Owing to the eccentric mounting by means of the elastic bearings 19, an elastic force acts on the shaft 20, so that the shaft 20 together with the base 7 of the display device 2 is pressed into a concave recess 21 of the receiving device. The recess 21 can be formed in particular in conformity with the base 7 of the display device 2. When the base 7 is pressed into the recess 21, the friction on the contact surface between the base 7 and the recess 21 increases, so that the display device 2 can be secured in its position or orientation with respect to the holding element 4.The holding element 4 can be formed in particular in two or more parts. For example, the counter positioning element 8 can be configured to be connected or clicked on to the body of the holding element after the neck 12 has been inserted into the slot of the rail 9.In some exemplary embodiments, the holding element 4 is formed in one piece. In such a case, the spring element 13, the sliding ring 14 and the slot 9 of the positioning element can each have a lateral slot for receiving the neck 12 of the counter positioning element 8.FIG. 2 shows a display assembly according to FIG. 1 in a released state. Specifically, FIG. 2 shows the holding device 3 in a state where the holding device 3 is operated by the user to change the position or orientation of the display device 2. The holding element 4 is pressed downward manually by the user, which is symbolically represented by a wide, downward-directed arrow. When pressing on the holding element, the spring element 13 is compressed in the vertical direction and the contact surface 17 between the underside of the rail 9 and the upper side of the foot part is relieved. It can also occur that instead of the contact point 17 a gap is formed between the underside of the rail 9 and the upper side of the foot part 11, which is symbolically represented by a gap with two opposing arrows on the right in the image.The fact that the contact surface 17 between the underside of the rail 9 and the upper side of the foot part 11 is relieved causes the frictional force between the positioning element 5 and the counterpositioning element 8 to be reduced, so that the counterpositioning element 8 can easily be moved back and forth along the rail 9 of the positioning element 5. The translatory movement of the counterpositioning element 8 or of the holding element 4 and thus of the display device 2 is symbolically represented in FIG. 2 by a horizontal double arrow.FIG. 3 shows a schematic cross section in plan view of the holding device according to FIG. 1 In particular, FIG. 3 shows a part of the rail 9 together with the slot 22, wherein the neck 12 of the rail insert of the counterpositioning element 8 of the holding element 4 has been accommodated in the slot 22. As can be seen from the view shown in FIG. 3, the neck 12 has an elongate, substantially elliptical cross section. In particular, the neck 12 has a biconcave shape in the circumferential direction and is designed such that the neck 12 can execute an axial pivoting movement within the slot 22, in particular about the vertical axis 18. The pivoting movement is symbolized in FIG. 3 by the curved arrow. Thus, the neck 12 and thus the holding element 4 can execute a translatory movement, symbolized by the straight double arrow, as well as a pivoting movement. Dashed lines illustrate possible positions of the foot part 11 or of the neck 12 in order to clarify the possible settings of the holding device 3.In some exemplary embodiments, the neck 12 is dimensioned such that the pivoting amplitude is restricted or the pivoting movement is restricted to a predefined angle range. It can thus be ensured in particular that the display device is not rotated too far or is not rotated multiple times, which could lead to overloading of cable connections possibly running along the holding element 4.The display device can be designed in particular as an instrument panel display or as a central display of the vehicle. In this case, the positioning element or the rail can be arranged on the surface of the dashboard. By positioning and optionally aligning the holding element, the display device held on the holding element can be positioned and aligned flexibly. In this case, the user can easily adjust the display device with one hand by the user pressing on the display device and simultaneously positioning it.Although at least one exemplary embodiment has been shown in the foregoing description, various changes and modifications may be made. The foregoing embodiments are merely examples and are not intended to limit the scope, applicability, or configuration of the present disclosure in any way. Rather, the foregoing description provides those skilled in the art with a plan for implementing at least one exemplary embodiment, and numerous changes may be made in the function and arrangement of elements described in an exemplary embodiment without departing from the scope of the appended claims and their legal equivalents. In addition, according to the principles described here, it is also possible for a plurality of modules or a plurality of products to be connected to one another in order to obtain further functions.List of reference characters1 Display assembly 2 Display device 3 Holding device 4 Holding element 5 Positioning element 6 Head part 7 Base 8 Counter positioning element 9 Rail 10 Rail insert 11 Foot part 12 Neck 13 Spring element 14 Sliding ring 15 Contact surface 16 Collar 17 Contact surface 18 Axis 19 Bearing 20 Shaft 21 Recess 22 Slot
