Description

Technical Field

[0001] The invention relates to a motor vehicle, in particular a passenger car, having a display unit, which is arranged on the inner side of the roof. Background Art

[0002] DE 10 2016 225 745 A1 discloses a screen for the interior of a vehicle, which is positioned on the inside of the roof and can be flipped between a use position and a top position. For example, a screen for second row seat occupants is arranged behind a first row of seats, including a driver's seat and a front passenger seat. If the screen is to be large enough, the distance between the screen and the occupant sitting in front of it must also be as large as possible so that the occupant can comfortably access the content displayed on the screen. In order to achieve the largest possible distance, the screen should be positioned as close to the front seat as possible. Such a screen is heavy, so that its support device must be dimensioned accordingly. The weight of the screen also plays a role in the collision requirements. Summary of the invention

[0003] The object of the present invention is to provide a motor vehicle having a display unit arranged on the inner side of the roof, wherein the distance between a user or passenger sitting in front of him and the displayed image is increased and the design of the display unit is simplified.

[0004] This object is achieved by a display unit having the feature combination of claim 1. Advantageous developments are specified in the dependent claims.

[0005] According to the invention, a motor vehicle has a display unit arranged on the inside of the roof. The display unit has an imaging device which is fixedly integrated and in particular cannot be disassembled by the user and a reflecting device which is arranged in a pivotable manner relative to the imaging device. The reflecting device is arranged so that the image generated by the imaging device becomes visible to a vehicle occupant (in particular located or sitting in front of the reflecting device) through the reflecting device. In addition to the reflecting device which is arranged in a pivotable manner, the display unit and the imaging device are arranged substantially parallel to the inside of the roof. In the non-use position of the reflecting device, the reflecting device is also arranged substantially parallel to the inside of the roof.

[0006] The imaging device is a display, screen or the like, eg based on LCD, LED or OLED technology and variants thereof.

[0007] As a result, the screen itself, together with its electrical connections and the electronics integrated therein, need not be arranged in a pivotable manner. As a result, the pivotable part of the display unit can be designed to be lighter, and thus the kinematic mechanism for pivoting the pivotable part of the display unit can also be designed for a lower weight. Compared to the screen, the reflector has a lower weight, which is also advantageous in the case of a frontal collision (in the case of a frontal collision, a person sitting in front of the reflector could hit the reflector), because the reflector has a lower mass.

[0008] The motor vehicle is preferably a passenger car with a passenger compartment and advantageously has at least a first row of seats and a second row of seats, and optionally also further rows of seats. Preferably, the display unit is designed for the second and / or third row of seats.

[0009] The reflector device is preferably formed by an intrinsically rigid plate, which can consist in particular of plastic, for example organic glass, fiber-reinforced plastic or of glass.

[0010] With regard to the reflected image, the reflective device should be sufficiently rigid to avoid distortion of the reflected image. A reinforcement frame may be provided for this purpose. However, it is better to construct a reflective device consisting of an inherently rigid plate (the inherently rigid plate itself is rigid) and is sufficiently rigid without an additional supporting structure, and the reflective device does not require a reinforced frame or similar structure, which simplifies the structure of the reflective device and also improves and streamlines the appearance of the reflective device.

[0011] According to a preferred improvement, the reflector has a reflective layer, which is polarized in particular according to the light emitted by the imaging unit. In other words, the reflective layer of the reflector can be coordinated with the characteristics of the imaging unit, for example, the light emitted from the imaging unit can be p-polarized or polarized with an additionally applied polarizer. The reflector can then advantageously be provided with a p-reflective layer, so that in particular the polarized light of the imaging unit is reflected, while other interior parts or other objects of the motor vehicle are not reflected. As a result, only the light of the imaging unit is reflected on the reflector.

[0012] According to a preferred development, the reflector device can be designed to be transparent or partially transparent.

[0013] The transparency of the reflective device enables the user sitting in front of it to look forward. This also makes it easier to look backward from the other side of the reflective unit. For example, when the display unit is arranged in the second row of seats, the driver of the motor vehicle in the first row of seats can get a better rear view through the internal rearview mirror. In addition, the transparent or translucent reflective device visually restricts the interior space of the vehicle less and has an aesthetic appearance.

[0014] Advantageously, the transparency of the reflective device is designed to be variable electrically or electronically. To this end, the reflective device can have a corresponding controllable or switchable layer similar to smart glass or switchable glass. The switchable layer can be implemented, for example, based on liquid crystal (LC), polymer dispersed liquid crystal (PDLC) or suspended particle device (SPD) technology.

[0015] According to another preferred improvement, the outer shape of the reflecting device is adapted to the reflected image. In particular, the reflecting device is not constructed as a square or a rectangle. The reflected image or the reflected image is generated by the relative positions of the imaging device and the reflecting device and the user's eye position. The surface of the reflecting device is arranged, for example, at an angle of 45 degrees + / - 10 degrees, preferably + / - 5 degrees relative to the surface of the imaging device. This means that from the user's perspective, the rectangular image emitted by the imaging device will not completely fill the reflecting device, which is also rectangular. Therefore, the width of the reflecting device can be implemented to continuously decrease as the distance from the pivot axis of the reflecting device increases, and this will not cut off any part of the image of the imaging device. Advantageously, based on the rectangular shape of the image of the imaging device, the reflecting device is trapezoidal, wherein the short side of the trapezoid is arranged away from the pivot axis.

[0016] Thus, the weight of the reflector device can be reduced by adapting the outer shape of the reflector device according to the reflected image. The reflector device thus also restricts the space in the vehicle interior less.

[0017] Preferably, the display unit (having the imaging device and the reflecting device) can rotate around an axis perpendicular to the display surface of the imaging device or around the vertical axis of the vehicle (Z axis in the vehicle coordinate system). Alternatively, although the display unit is not configured to be rotatable around the Z axis, it is fixedly fixed in a plane parallel to the longitudinal direction of the vehicle (X axis) and the transverse axis of the vehicle (Y axis) to rotate at a specific angle relative to the transverse axis of the vehicle (Y axis).

[0018] Therefore, the position of the reflected image can be appropriately adapted to the user sitting in front of it, and at the same time the reflected image can be rotated or rotated away from the field of view of the person sitting next to the user, so that the other person cannot see it or at least cannot see it easily.

[0019] The display unit can be rotated, for example, within an angular range of −10 degrees to +10 degrees, or the display unit can be mounted fixedly about the vehicle vertical axis so as to be rotated relative to the vehicle transverse axis by an angular range of −10 degrees to +10 degrees.

[0020] The imaging device can also be pivotable, for example, about a vehicle transverse axis (y-axis in the vehicle coordinate system), for example, by -10 degrees to +10 degrees. As a result, the display unit can be better adapted to the seat height of the user sitting in front of it.

[0021] The pivoting of the imaging device around the Y-axis can be performed manually or electrically. In particular, the pivoting around the Y-axis can be performed automatically based on the eye position of the user sitting in front of it detected by the corresponding sensor device.

[0022] Furthermore, the shielding plate can be arranged in the region of the rear edge of the imaging device.

[0023] The shielding plate limits the direct sight line of the user sitting in front of it to the image of the imaging device or completely blocks the sight line. Through the shielding plate, the user sitting in front of it will not be distracted by the image of the imaging device, but only has the reflected image of the reflecting device in the field of vision.

[0024] The visor can be designed to be adjustable, so that it can be adjusted, for example, to different head positions or eye positions of a user sitting in front of it.

[0025] Alternatively or in addition to a (mechanical) baffle, the imaging device may be provided with a privacy filter or privacy layer that blocks or prevents vision outside a certain viewing angle, so that a user sitting in front of it cannot directly see the image of the imaging device, but can only see the reflected image.

[0026] The image of the imaging device can preferably be designed to be zoomable, in particular automatically or manually zoomable.

[0027] Therefore, the size of the image can be optimally adjusted depending on the position of the reflecting device, the eye position of the user sitting in front of it and the position of the imaging device.

[0028] The image of the imaging device may be automatically zoomable based on the eye position of a user sitting in front of it (which eye position may be detected by a camera, for example) and / or the position of the reflecting device and / or the position of the imaging device.

[0029] According to a preferred development, the reflector device is pivotable between a non-use position, in which the reflector device is, for example, substantially parallel to the imaging device, and a use position.

[0030] Thus, the reflective device can be pivoted when not in use in such a way that it no longer restricts the vehicle interior and does not constitute an obstacle, for example, when entering or leaving the motor vehicle.

[0031] The reflective device may be capable of automatically pivoting to a non-use position and a use position as required. The reflective device may be capable of automatically pivoting to a use position based on the user's eye position.

[0032] The display unit can have an electric drive for pivoting the reflective device.

[0033] The reflective device and the imaging device can extend continuously over at least half the width of the inner side of the vehicle roof, preferably over at least two thirds of the width, in particular substantially over the entire width.

[0034] The reflective device can be mounted so as to be pivotable about a real or virtual, fixed or variable pivot axis which extends in the transverse direction of the vehicle.

[0035] The imaging device can have an aspect ratio of 4:3 or 16:9 or 21:9 or 32:9, wherein the reflector device can have corresponding dimensions and can be correspondingly trapezoidal if necessary.

[0036] The display unit can be mounted so as to be movable in the longitudinal direction of the vehicle (X axis). In particular, it can have an electric drive for movement in the longitudinal direction of the vehicle.

[0037] The display unit may be fixed and supported on the left top side frame and the right top side frame.

[0038] The above-mentioned features can be combined with one another as desired and sensible as possible. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following is a brief description of the accompanying drawings.

[0040] Figure 1 A schematic side view shows a display unit of a motor vehicle according to an exemplary embodiment of the present invention in a non-use position.

[0041] Figure 2 A schematic side view shows a display unit of a motor vehicle according to an exemplary embodiment of the present invention in a usage position.

[0042] Figure 3 A schematic plan view of a display unit of a motor vehicle according to an exemplary embodiment of the present invention is shown, viewed from below or from above. DETAILED DESCRIPTION

[0043] Below, refer to Figures 1 to 3 Embodiments of the present invention are described.

[0044] As in Figure 1As shown in , the motor vehicle according to the embodiment has a display unit 1 which is fixedly and non-detachably integrated in the roof or roof 9 for the user, and which is arranged, for example, in the area of ​​the rear seat, in particular the second row of seats, for the rear seat occupants. The display unit 1 can be arranged specifically for a specific seat, but the display unit can also be arranged so that it can be seen from multiple seats in the row of seats. The display unit 1 has a display 3, i.e. an imaging device, which is arranged parallel to the side of the roof or roof 9 facing the vehicle interior. In addition, the display unit 1 has a reflection device 5, which can be pivoted relative to the display 3 around an axis 53. The axis 53 extends substantially parallel to the vehicle transverse axis (i.e. the y-axis in the vehicle coordinate system) and is constructed in the area of ​​the front section of the display unit 1. As explained below, the axis 53 can also extend slightly inclined relative to the vehicle transverse axis. The occupant 100 sitting behind the display unit 1 in the driving direction is schematically shown with a head and eyes 101. Furthermore, part of the display unit 1 is a baffle 13 which is arranged behind the display 3 in the direction of travel and limits the occupant 100's direct view of the display, or even completely prevents him from seeing the display. The function of the baffle 13 depends of course on the position of the occupant's 100 eyes 101 relative to the display. In the embodiment described, the baffle 13 is immovable. Alternatively, the baffle 13 can also be embodied as adjustable, so that it can be adjusted manually or automatically to the eye position.

[0045] The reflecting device 5 comprises an intrinsically rigid plate without further supporting structures, which is made of transparent organic glass. In addition, the reflecting device has a reflecting layer, which reflects the image of the display.

[0046] The reflective device can also be embodied as opaque, or the transparency of the reflective device can be designed to be electrically or electronically variable, similar to an intelligent, switchable glass pane by means of LC, PDLC or SPD technology.

[0047] exist Figure 1 In the side view of , the reflector 5 is in the non-use position and is arranged parallel to the display 3. Figure 2 In the side view of FIG. 5 , the reflecting device 5 is pivoted downward about the axis 53 by an angle of approximately 45 degrees.

[0048] When the display 3 is switched on, the image of the display surface of the display 3 is reflected on the reflective device 5. A reflected image 51 is formed which, from the perspective of the occupant 100, appears to float in space behind the reflective device 5, even if the front seat 15 or the headrest of the front seat 15 is located there.

[0049] Furthermore, the display unit 1 can be rotatable as a whole by several degrees around the vertical axis 11 (Z axis in the vehicle coordinate system), for example within an angle range of -10 to +10 degrees. Thus, the display unit 1 can be adapted to the occupant 101, for example when the occupant is sitting slightly tilted.

[0050] As in Figure 3 As shown in , two display units 1 can be arranged side by side so that the corresponding passengers on two adjacent seats can use the display units 1 independently of each other. In this case, it is particularly meaningful that the display units 1 can be rotated about their vertical axis 11 or at least slightly rotated toward each other. Figure 3 As shown in , the left display unit 1 is turned a few degrees to the left and the right display unit 1 is turned a few degrees to the right. As a result, the corresponding reflected image is less visible to the person sitting next to the vehicle. The position of the display unit 1 in which the display unit is parallel to the vehicle transverse axis is shown by means of a dashed line.

[0051] As especially Figure 3 As can be seen in FIG. 5 , the reflector 5 has a trapezoidal shape. Here, the rear edge of the reflector 5 (ie, the lower edge in the use state) is shorter than the front edge of the reflector 5 (close to the pivot axis 53). The trapezoidal shape is Figure 2 The use position shown in FIG. 1 is adapted to the angular position of the reflector 5 and thus to the reflected image 51. The trapezoidal shape is designed so that the reflected image 51 also just completely shows the image of the imaging device 3. The advantage of the trapezoidal shape is that the reflector 5 visually and practically restricts the interior space less than a rectangular reflector, without limiting the function of the reflected image 51. In addition, the reflector 5 is therefore also lighter.

[0052] As in Figure 1 As shown in , the imaging device 3 can also be pivotable around the vehicle transverse axis 33 (i.e., an axis parallel to the Y axis in the vehicle coordinate system) within a limited angle range, i.e., a few degrees, for example -10 degrees to +10 degrees. This enables additional adjustment possibilities with respect to the eye position of the occupant 100.

[0053] The rotation of the reflector 5 around the axis 53 and the display around the axis 33 and also the rotation of the entire display unit 1 around the axis 11 can be automatically realized by means of an electrical adjustment drive based on the eye position of the user 100 detected by the sensor. Alternatively, all these adjustments can be performed manually by the user 100.
