Description

[0001] One aspect of the invention relates to a vehicle operating and / or display device. This device comprises an operating and / or display unit. It also comprises a support part. The operating and / or display unit is attached to this support part with a fastening device. The support part is a separate component from the operating and / or display unit.

[0002] Vehicle operating and / or display devices are known in a wide variety of designs. Individual components are typically connected to one another by detachable mechanical connections, such as screw connections. It may happen that individual components of such an operating and / or display device, which are aligned or adjusted relative to one another, are subjected to specific assembly forces during such fastening, which can lead to misalignment of the position and / or generate undesirable mechanical stresses in the components.

[0003] The object of the present invention is to provide a vehicle operating and / or display device in which the attachment of individual components to one another is improved. Accordingly, the object of the invention is also to provide a vehicle with such a vehicle operating and / or display device.

[0004] This object is achieved by a vehicle operating and / or display device according to the features of claim 1.

[0005] One aspect of the invention relates to a vehicle operating and / or display device. This device comprises an operating and / or display unit. It also comprises a support part. The operating and / or display unit is attached to this support part with a fastening device. The support part is a separate component from the operating and / or display unit.

[0006] The fastening device has at least one clamping device. The clamping device has a clamping element, which is arranged in particular on the carrier part. In addition, the clamping device has a clamping element receptacle separate from the clamping element. This is arranged in particular on the operating and / or display unit. To fasten the operating and / or display unit to the carrier part, the clamping element is clamped in the clamping element receptacle. This creates a particularly advantageous mechanically holding and fixing connection. This also ensures that these positions can be maintained, in particular after the positional alignment or adjustment between the operating and / or display unit and the carrier part by means of such a clamping device.Furthermore, this also makes it possible to achieve a virtually force-free fixing of the components to one another after centering these components in at least one spatial direction, in particular in a direction oriented perpendicular to the clamping direction. Undesired mechanical stresses in at least one of these components can thus be better avoided. Particularly in the case of non-destructively irremovable connections, as is the case with adhesive or welded joints, for example, such mechanical stresses can also lead to a distortion of at least one component, which is disadvantageous with regard to the exact position of the components to one another, so that this set position can no longer be maintained. It is precisely with this specific non-destructively removable connection in the form of the clamping device that these influences can at least be significantly reduced.In light of this, a force-free or force-reducing fixation is achieved by the clamping device in comparison to the other mechanical connections mentioned above.

[0007] In one embodiment, the clamping element receptacle is a through hole. The clamping element receptacle can also be a blind hole. This arrangement is such that the clamping element is also inserted into the clamping element receptacle. This also results in a certain mechanical positioning and stability relative to each other, so that the clamping effect achieved by these two components interlocks. This prevents unwanted loosening without reducing the clamping force.

[0008] In one embodiment, the clamping element has a longitudinal axis. To create the clamping effect, the clamping element can be spread open in the clamping element receptacle perpendicular to the longitudinal axis. This allows for particularly precise adjustment of the clamping effect and thus also of the clamping connection between the clamping element receptacle and the clamping element. This is also advantageous in that the clamping element can initially be inserted into the clamping element receptacle in its basic state, in which it is not spread open. This makes this pre-assembly, or rather the achievement of this intermediate assembly state, very simple and requires little effort. Starting from this intermediate assembly state, in which the elements are then guided one inside the other in the axial direction, the clamping element can then be spread open in a particularly simple and targeted manner.

[0009] In one embodiment, the clamping element has an insertion channel into which an expansion element can be inserted to expand the clamping element. As a result, the change in shape, in particular the spreading of the clamping element, is achieved in a particularly advantageous and controlled manner by this separate expansion element. Through this very continuous enlargement of the clamping element, in particular in a direction perpendicular to the longitudinal axis, the clamping effect with the clamping element receptacle can be adjusted precisely and in a controlled manner. This also contributes significantly to the advantages mentioned above. With such a separate expansion element, which can also be inserted centrally in the clamping element and is movable relative to it, the spreading of the clamping element can also be carried out very evenly.Starting from the longitudinal axis, the clamping element is thus extended radially outward very evenly in the circumferential direction around the longitudinal axis, so that a very uniform clamping action can be achieved even with the clamping element holder viewed in the circumferential direction of the longitudinal axis. This prevents unwanted tilting of the clamping element relative to the longitudinal axis and thus asymmetric clamping effects with the clamping element holder.

[0010] In one exemplary embodiment, the clamping element has local press-in parts on an outer side, in particular an outer side that faces an inner side of the clamping element receptacle. These are intended to press into an inner side of the coupling element receptacle when the clamping effect is established. This is very advantageous in that the clamping effect can thus be generated relatively uniformly and can also be maintained once the final clamping state between the aforementioned components has been reached. On the other hand, this is particularly advantageous in that axial movements and thus movements in the direction of the longitudinal axis of the clamping element between the clamping element and the coupling element receptacle, in particular when the clamping element is spread apart, can be prevented or at least minimized.This can be done in such a way that the position set before clamping, in particular axially, between the carrier part and the operating and / or display unit is maintained.

[0011] In one embodiment, the press-in parts are designed as elongated, pointed elements. They are particularly elongated elements oriented in the direction of the longitudinal axis. These pointed elements are therefore also designed such that, viewed perpendicular to the longitudinal axis, they taper outward, with the tip thus oriented away from the longitudinal axis. This advantageously results in very small contact, in particular a linear contact, between a clamping element and the inside of the coupling element receptacle. This enables the clamping element to be pressed particularly firmly into the coupling element receptacle.

[0012] In one embodiment, the clamping element has a longitudinal axis. In particular, it has a plurality of clamping element parts that are arranged in the circumferential direction around the longitudinal axis, in particular arranged at a distance from one another. The clamping element parts can be elastically bent outwards away from the longitudinal axis, independently of one another. This improves the functionality of the clamping element with regard to the most uniform clamping effect possible with the coupling receptacle. Furthermore, the spreading of the clamping element is supported by directly inserting, for example, plugging or screwing in, the expansion element into the central insertion channel of the clamping element, so that here too these clamping element parts can be pressed outwards very uniformly in the radial direction.

[0013] In one embodiment, the operating and / or display unit has a base part, in particular a trough-shaped one. The at least one coupling element receptacle is integrated into this base part. This means that it is manufactured in one piece therewith. It is possible for several separate coupling element receptacles to be integrated into the base part. For example, four such coupling element receptacles can be formed therein. If the base part is square with respect to its basic shape, in particular rectangular, two coupling element receptacles can be formed on each of the shorter longitudinal sides of this square. These are then provided for the engagement of several corresponding coupling elements.

[0014] In one embodiment, the operating and / or display unit comprises a base part, in particular a trough-shaped one, and a separate operating and / or display module. This module is movably mounted on the base part. This allows the operating and / or display module to be individually positioned. In particular, specific positions relative to the support part can also be set.

[0015] In contrast, the base part is preferably arranged in a fixed position on the support part, in particular by means of the clamping devices mentioned.

[0016] In one embodiment, mounting in only one spatial direction allows movement of the control and / or display module relative to the base part. In particular, this spatial direction is oriented perpendicular to the plane of the plate-shaped control and / or display unit. This allows the control and / or display module to be raised and lowered relative to the base part in a quasi-intended and deliberate manner. In the other two spatial directions, the control and / or display module is arranged in a positionally fixed position relative to the base part.

[0017] In one embodiment, this movement in this spatial direction can be effected by an actuator of the operating and / or display unit. This actuator can be controlled individually in order to achieve this relative movement of the aforementioned components to one another, particularly in only one spatial direction.

[0018] In one embodiment, the control and / or display module is mounted on the base part by means of several springs. In particular, these springs can be leaf springs. This further supports the individual position adjustment in this spatial direction. This is because the actuator can set the specific position, which is supported and maintained by these springs. These springs then also enable a uniform, particularly in one plane, relative movement of the control and / or display module to the base part.

[0019] In one embodiment, these springs are held by pins in pin receptacles formed on the base part. This improves the overall mounting and operating principle.

[0020] In one embodiment, the operating and / or display device has a circuit board, on the upper side of which positioning elements, in particular positioning pins, are formed, which engage in positioning receptacles in a housing for a display of the operating and / or display unit. In particular, these positioning elements are different from the aforementioned plug pins and the aforementioned springs. These positioning elements also support position adjustment or a specification of the position of the components relative to one another, in particular in the two spatial directions that are perpendicular to the spatial direction in which the operating and / or display module is movable relative to the base part.

[0021] A further aspect of the invention relates to a vehicle with such a vehicle operating and / or display device.

[0022] Embodiments of the invention are explained in more detail below with reference to schematic drawings. They show: Fig. 1 an exploded view of an embodiment of a vehicle operating and / or display device according to the invention; Fig. 2 a representation of the components according to Fig. 1 in partially assembled condition; Fig. 3 the representation according to Fig. 2 in one to Fig. 2 different perspectives; Fig. 4 an assembled state of the components according to Fig. 1; Fig. 5 an exploded view of components of an operating and / or display unit of the vehicle operating and / or display device; Fig. 6 the representation according to Fig. 5 in one to Fig. 5 different perspectives; Fig. 7 a perspective view of an embodiment of a clamping element of a clamping device of the vehicle operating and / or display device; Fig. 8 a perspective view of a portion of the mounted state of the vehicle operating and / or display device; and Fig. 9 a sectional view of the representation in Fig. 8.

[0023] In the figures, identical or functionally identical elements are provided with the same reference symbols.

[0024] In Fig. 1 shows an exploded view of an embodiment of a vehicle operating and / or display device 1.

[0025] The vehicle operating and / or display device 1 can be arranged in a vehicle 2. The vehicle operating and / or display device 1, which is referred to below as the operating and / or display device 1, has a support part 3 and an operating and / or display unit 4. The operating and / or display unit 4 has a base part 5. This is designed like a trough. In addition, the operating and / or display unit 4 has an operating and / or display module 6. This operating and / or display module 6 has a cover 7. This cover 7 can be made of glass, for example. A display 8, which can be an OLED display, for example, is covered by this cover 7. The display 8 is also part of the operating and / or display module 6. In addition, the operating and / or display module 6 has a housing 9 for this display 8. An actuator 10 is also part of the operating and / or display module 6.In one embodiment, this actuator 10 can be arranged in an actuator housing 11, which is also a component of the operating and / or display module 6. Furthermore, the operating and / or display module 6 has a circuit board 12. In the exemplary embodiment, this circuit board 12 has a through-hole 13. The actuator 10 and the actuator housing 11 extend through this hole in the assembled state.

[0026] In addition, springs, in particular leaf springs, are part of the operating and / or display unit 4. These leaf springs 14a to 14d enable the mounting of the operating and / or display module 6 on the base part 5. In particular, this enables a movable arrangement of this operating and / or display module 6 on the base part 5. By means of these strip-shaped leaf springs 14a to 14d, a movement of the operating and / or display module 6 relative to the base part 5 in a specific spatial direction, in particular only in this spatial direction, can be achieved. This relative movement possibility is in the spatial direction R ( Fig. 2) which is perpendicular to the plane in which the plane of the operating and / or display module 6 is spanned.

[0027] The leaf springs 14a to 14d are arranged on the underside of the circuit board 12, and on the other hand, in receptacles in the base part 5. They can be secured with screws and / or pins.

[0028] As furthermore in Fig. As can also be seen in Figure 1, the circuit board 12 has several positioning elements, here four positioning elements 15, 16, 17, and 18. These extend from a top side of the circuit board 12 to the components arranged above it, namely the housing 9, the display 8, and the cover 7.

[0029] In this regard, the housing 9 has receptacles on its underside facing the circuit board 12, into which these positioning elements 15 to 18 can extend. This enables a positional fixation between the circuit board and the housing 9.

[0030] In addition, it can be seen that the carrier part 3 has several, in particular four, clamping elements 19, 20, 21 and 22 ( Fig. 3). These are part of a clamping device K. By means of this clamping device K, the operating and / or display unit 4 can be clamped to the carrier part 3. For this purpose, the base part 5 in particular has a plurality of integrated and thus integrally formed clamping element receptacles 23, 24, 25 and 26. In the exemplary embodiment, these are designed as holes. They can also be designed as non-through holes and, for example, be designed as blind holes. In the exemplary embodiment shown here, the four coupling element receptacles 23 to 26 are formed on opposite short sides of the base part 5, which is square, in particular rectangular.

[0031] To create the clamping effect, separate expansion elements 27, 28, 29, and 30 are also provided. These are intended for direct insertion into the coupling elements 19 to 22. In particular, the expansion elements 27 to 30 are screws.

[0032] In Fig. 2 is the representation according to Fig. 1, where, on the one hand, the housing 9 is assembled with the display 8 and the cover 7. This intermediate module 31 represents a component that, in the assembled state, is movable relative to the base part 5 and the circuit board 12 in the spatial direction R. This can be deliberately initiated by means of the actuator 10.

[0033] In addition, Fig. 2 shows the receptacles 32, 33, 34, and 35 integrated into the base part 5, which are provided for receiving the leaf springs 14a, 14b, 14c, and 14d. As can be seen, these receptacles 32 to 35 are also preferably formed on the short longitudinal sides of the rectangular shape of the base part 5. They are separate and adjacent to the clamping element receptacles 23 to 26.

[0034] In Fig. 3 is the component arrangement as shown in Fig. 2, in a different perspective, namely obliquely from below. By coupling the module 31 to the base part 5 by means of the leaf springs 14a to 14d, movement in the plane perpendicular to the spatial direction R is preferably prevented.

[0035] In Fig. 4 shows the assembled state of the operating and / or display device 1.

[0036] In Fig. 5 shows an exploded view of the display 8, which is arranged in the housing 9. In addition, the leaf springs 14a to 14d are arranged on the housing 9, in particular on its underside 9a ( Fig. 6), in particular by means of screws 36, 37, 38 and 39 ( Fig. 3). As can also be seen, the actuator housing 11 is screwed to this underside 9a. This is shown in Fig. 6 shown.

[0037] In addition, further coupling elements, in particular screws 40, 41, 42 and 43, are shown in Fig. 5, by means of which the leaf springs 14a to 14d can be fastened to the base part 5, in particular in the receptacles 32 to 35. As further shown in Fig. 5, the base part 5 has a recess 44 into which the actuator housing 11 extends in the assembled state.

[0038] In Fig. 6 is the component arrangement according to Fig. 5 is shown in a different perspective, namely diagonally from below.

[0039] Also shown here are positioning receptacles 9b, 9c, 9d, 9e in the housing 9, particularly its underside 9a. These are designed to accommodate the positioning elements 15, 16, 17, 18.

[0040] In Fig. Figure 7 shows an enlarged partial view of a portion of the support part 3. It shows an exemplary embodiment of a clamping element, in this case the clamping element 19. As can be seen, the clamping element 19 is integrated and thus formed in one piece with the support part 3. The support part 3 can be made of plastic, for example. It can be an injection-molded component, for example.

[0041] The clamping element 19 has a longitudinal axis A. In particular, the clamping element 19 is formed on a base 45. In the exemplary embodiment, the clamping element 19 is elastically deformable, in particular expandable, in a direction perpendicular to the longitudinal axis A and thus in particular in a plane perpendicular to the longitudinal axis A. In the exemplary embodiment, the clamping element 19 has a plurality of clamping element parts 46, 47, 48, 49, 50 and 51. These clamping element parts 46 to 51 are rectilinear and extend parallel to the longitudinal axis A. They are preferably connected to one another in a lower region 52 in the circumferential direction around the longitudinal axis A. Viewed upwards in the vertical direction, they are then arranged at a distance from one another in the circumferential direction around the longitudinal axis A and are each designed to project freely towards the top. This enables elasticity perpendicular to the longitudinal axis A.As can also be seen, the clamping element parts 46 to 51 preferably each have at least one radially outwardly projecting press-in part 53 on their outer sides facing away from the longitudinal axis A. For the sake of clarity, this press-in part 53 is shown in . Fig. 7 is provided with a corresponding reference numeral only for the clamping element part 47. In particular, it can be provided that such a press-in part is an elongated pointed element. In particular, this press-in part is intended to be pressed or pressed into an inner side of a coupling element receptacle 23 to 26 in the clamped state. The shape as a pointed element achieves a linear contact with the inner side of the coupling element receptacle 23 to 26. In particular, this press-in part 53 also ensures that, viewed in the direction of the longitudinal axis A, a relative movement between the clamping element 19 and the clamping element receptacle 23 to 26 is avoided when the clamping effect is generated, and thus a related relative movement between the carrier part 3 and the operating and / or display unit 4 in this direction is also avoided.

[0042] In Fig. Figure 8 shows a perspective view of a portion of the assembled operating and / or display device 1. The cover 7 is shown transparent here, so that the underlying structure can be seen. As can be seen, the coupling element 19 is inserted into the coupling element receptacle 23. In addition, the expansion element 27 is also inserted axially into an insertion channel 54 ( Fig. 7) of the coupling element 19 is inserted from below, so that the coupling element parts 46 to 51 are spread outwards in a plane perpendicular to the longitudinal axis A and are pressed in a clamping manner against an inner side 23a of the coupling element receptacle 23 in order to produce the clamping effect.

[0043] In Fig. 9 is a representation of the arrangement according to Fig. 8 along the section line IX-IX. As shown in Fig.As can also be seen in Figure 9, a distance a1 between the cover 7 and an upper edge 3a of the side walls of the support part 3 can be specifically adjusted in the vertical direction. This is made possible in particular by the relative mobility in the spatial direction R of this intermediate module 31. In particular, the actuator 10 can be actuated accordingly for this purpose.

[0044] Preferably, this setting of the distance a1 and preferably a distance a2 to a boundary wall 55 is set before the clamping effect is generated. This boundary wall 55 can be a boundary wall of a receiving recess in which the operating and / or display device 1 is received. In particular, this clamping device 22 can then also be used to achieve force-free fastening in the spatial direction R. It is therefore advantageously achieved by the clamping device K in particular that the previously set distances a1, and in particular also a2, are maintained when the clamping device K establishes its clamping effect. Furthermore, it can also be seen that the base part 5 can be positioned at a distance a3 from the inside of the side wall of the carrier part 3, so that contact-free arrangement and storage is also possible here.

[0045] Therefore, it is possible for the operating and / or display unit 4 to be arranged in a fixed position on the support part 3 in all three spatial directions.
