Description

The invention relates to a motor vehicle with a control panel module and a vehicle shell. The vehicle shell represents the structure or frame of the motor vehicle. A switch panel module is installed in such a vehicle shell in the front area in front of the vehicle seats for the driver and front passenger, for example to provide a switch panel and / or a center console. The invention also includes a cross member that can be built into the vehicle shell, for example in order to be able to carry the switch panel module in the vehicle shell or to be able to fasten it there.

Such a cross member is for example in the DE 10 2014 019 023 A1 described. A cross member is a structural component that contributes to the stability or structure of the vehicle shell. In the cited publication it is described that electrical components can be installed in a cavity of such a cross member, so that the cross member simultaneously serves as a housing for an electronic device. This allows the cross member and electronic device to be arranged in a space-saving manner in the area under the control panel module. However, this requires a special manufacturing process, since the electronic components must be built into the cavity in the cross member. Repairing the electronic device is also costly as a result.

One possible electronic device that can be provided in a control panel module is a display device with a movable screen, as it is, for example, from the DE 10 2006 025 383 B3 is known. Because of the small installation space inside the control panel module, such a screen must be stored very compactly when it is inserted into the control panel module. Therefore, a very complex mechanism for extending and retracting the screen is necessary.

In the DE 10 2018 208 250 B3 describes how a movable screen can be compactly stored in a panel module by making the screen foldable. This solution is therefore only of interest for foldable screens.

The invention is based on the object of providing a display device in the area of a switch panel module of a motor vehicle which has an extendable screen that can be extended from the switch panel module and sunk back into it.

The object is achieved by the subjects of the independent claims. Advantageous embodiments of the invention are described by the dependent claims, the following description and the figures.

The invention provides a motor vehicle which, in the manner known per se, has a vehicle shell in which a control panel module can be installed or inserted. A cross member is provided in the vehicle shell, by means of which a left side wall or A-pillar of the vehicle shell on the one hand and a right side wall or A-pillar of the vehicle shell on the other hand are connected to one another in the motor vehicle. In addition or as an alternative to the connection, the control panel module can be arranged on the cross member. The dash panel module is visible from a vehicle interior of the motor vehicle, that is, a vehicle passenger can see a surface of the dash panel module.

An instrument panel and / or a center console, for example, can accordingly be implemented by the switch panel module. For this purpose, an extendable display device is provided in the control panel module, that is to say an actuator device is set up to move a screen of the display device between an extended state and a retracted state. In the extended state, the screen protrudes from the dashboard module into the vehicle interior; in the retracted state, the screen is partially or completely retracted into the dashboard module. This movement can be generated by the actuator unit as a function of a control signal that can be generated, for example, by a control unit of the motor vehicle in order to extend the screen, for example when the motor vehicle is started, and / or to retract the screen when the motor vehicle is switched off.

As already stated, the installation space inside or below the control panel module can be limited or narrow. In particular, the cross member, which is located behind and / or below the dashboard module from the point of view of a vehicle passenger, can take up an installation space area in which the screen and / or the actuator unit are to be accommodated or arranged.

In order to obtain installation space below or within the control panel module for both the cross member and the display device (or at least the screen of the display device), the invention provides that a shaft is formed in the cross member and the screen is at least partially arranged in the shaft. The screen is located wholly or partially in the shaft in each case: during the retracted state and / or the extended state and / or during of movement between the retracted and extended states.

An installation position of the cross member can be enforced, for example, that a steering and / or an airbag of the motor vehicle is to be held by the cross member. Thus, the position of the cross member can be fixed under or within the control panel module. So that the cross member is not "in the way" when it comes to moving or positioning the screen of the display device, the invention provides that the area of the cross member that would be "in the way" of the screen is hollowed out or cut out by the Cross member has a shaft in which the screen can be arranged at least partially when it is retracted and / or extended and / or is currently being moved.

The invention results in the advantage that the cross member can be provided inside or below the switch panel module and that installation space is still available for arranging the screen. As a result, the screen can, for example, also be designed as a rigid screen, that is to say non-foldable screen, if this is desired.

The invention also encompasses embodiments which result in additional advantages.

The shaft in the cross member does not have to result in the stability and / or rigidity of the cross member being impaired. Rather, the cross member can even acquire additional rigidity as a result. For this purpose, it is provided in one embodiment that the shaft has inner walls through which an upper side of the cross member and an underside of the cross member are connected in the cross member. In other words, in addition to the outer wall of the cross member, at least one additional inner wall is also drawn into the shaft. Such an inner wall can act as an additional reinforcement for the cross member, as is already known from so-called bulkheads for cross members. By providing at least one additional wall in the shaft, in particular the flexural rigidity of the cross member can be increased compared to a cross member with a shaft without an inner wall.

In one embodiment, the actuator unit is also held in the control panel module by the cross member. In other words, the cross member is advantageously used to hold the actuator unit in the motor vehicle. Since the cross member can be connected to the vehicle shell, this results in a direct connection or attachment to the side walls or A-pillars via the cross member. This increases the vibration rigidity, so that the screen in the vehicle interior in the extended state is kept quiet or with little vibration even during a journey.

In one embodiment, the screen is held between rotatably mounted rollers, for example rubber rollers, and / or between wheels, for example rubber-coated wheels or gear wheels. The bearings for the rotatable mounting of the rollers and / or wheels are held by the cross member. In other words, the screen can also be supported against vibrations by being framed between rollers and / or wheels which are also directly connected to the side walls and / or A-pillars of the motor vehicle directly via the cross member.

In one embodiment, the control panel module is attached to the cross member. In other words, even the control panel module can be carried or held by the cross member. Thus, for example, a gap or a passage opening through which the screen is extended and retracted through a surface of the control panel module can be kept steady relative to the screen. In this way, a gap between the surface or the passage opening of the control panel module on the one hand and the screen on the other hand can be maintained.

In one embodiment, the cross member is designed as a sheet metal shell part. As a result, the shaft can be subsequently cut or punched into the cross member, and only one outer wall of the cross member, namely the sheet metal, has to be severed. Alternatively, it can be provided that the cross member is designed as a die-cast part, whereby the shaft can then advantageously be fixed directly by the casting mold.

In one embodiment, the actuator unit has a linear motor for moving the screen. A linear motor has the advantage that it has a lever arm on the screen that can be selected to be equally stable for all positions of the screen. Additionally or alternatively, the actuator unit can have a spindle drive, which has the advantage that only the spindle has to be moved spatially in order to move the screen. The actuator unit does not need a spatial travel path for, for example, an electric rotor of an electric motor. Rather, this can be designed as a rotary motor.

In one embodiment, the shaft is designed as a blind hole, that is, the shaft does not represent a passage opening through the cross member, but ends in the cross member. Thus can the cross member can also be used as protection for the screen. Alternatively, in one embodiment, the shaft is designed as a through opening, which has the advantage that a “long screen” can also be arranged in the switch panel module, that is to say a screen that has a screen height that is greater than a diameter of the cross member.

In one embodiment, an inner contour of the shaft and an outer contour of the screen are designed to correspond to one another. The shape of the shaft corresponds to the shape of the screen. In other words, the shaft can surround or enclose the screen with a constant gap width, with “constant gap width” being understood to mean a gap width that fluctuates along the circumference of the screen or the course of the gap by a maximum of 20 percent, in particular a maximum of 10 percent . The gap width can, for example, be in a range from 0.3 centimeters to 1 centimeter.

The motor vehicle according to the invention is preferably designed as a motor vehicle, in particular as a passenger vehicle or truck, or as a passenger bus.

In order to provide the motor vehicle according to the invention, a cross member with a shaft must be provided for the vehicle shell. Such a cross member is also part of the invention and is designed to connect a left side wall or A-pillar of the vehicle shell of the motor vehicle on the one hand and a right side wall or A-pillar of the vehicle shell of the motor vehicle on the other hand. The cross member has the said shaft, which is accessible from at least one outside of the cross member. If it is only accessible from one outside, then it is the said blind hole; if it is continuous through the shaft, that is, from an upper side of the cross member to an underside, then it is the said through opening.

The invention also includes further developments of the cross member according to the invention which have features as they have already been described in connection with the further developments of the motor vehicle according to the invention. For this reason, the corresponding developments of the cross member according to the invention are not described again here.

The invention also includes such implementations or devices in which the features of the described embodiments are combined.

In the control panel module 13th can be a display device 17th be provided, of which in 1 a retractable screen 18th is shown. Of the screen 18th can through a slot or an opening 19th the surface 14th of the control panel module 13th in the vehicle interior 11 be moved in or out. 1 shows the screen 18th in a retracted state S0 in which the screen 18th wholly or partially in the control panel module 13th is sunk. In the retracted state S0 can the display area 20th in the control panel module 13th be sunk or arranged, whereby it can be protected from damage, for example.

1 also shows how in the retracted state S0 the screen 18th so deep or far into the panel module 13th retracted or retracted that the screen 18th in the cross member 15th protrudes into and / or through this. The cross member can do this 15th a shaft 21 have into which and / or through which the screen 18th can be moved or guided.

A contour of an edge or an inner contour 22nd of the shaft 21 can with a perimeter contour of the screen 18th correspond so that along the circumference or along the inner contour 22nd a gap between the shaft 21 and screen 18th can be constant in the manner described.

2 shows the screen 18th in an extended state S1 , in particular, it can be a fully extended state S1 Act. In the extended state S1 can by a vehicle passenger of the motor vehicle 10 a display area 20th Of the screen 18th looked at or seen.

3 and 4th each illustrate a cross section, where 3 the retracted state S0 and 4th the extended state S1 illustrated. The display device 17th can in addition to the screen 18th an actuator unit 23 provide through which the screen 18th in the control panel module 13th between the retracted position or the retracted state S0 and the extended position or state S1 can be moved or moved. The actuator unit 23 can do this with an electric motor 24 have, which can be, for example, a linear motor and / or a spindle drive with a spindle 25th can provide. The actuator unit 23 can by a control signal 26th be controlled, which can be generated for example by a control unit of the motor vehicle. The actuator unit 23 can have a mechanical attachment 27 (in 3 shown only symbolically) on the cross member 15th be held.

In 3 is also shown how via a mechanical bracket 28 also the control panel module 13th on the cross member 15th can be held.

For the screen 18th can rollers 29 and / or wheels 30th be provided through which the screen 18th in relation to a horizontal movement can be propped up so the screen 18th for example, in the event of a vibration, as it occurs while the motor vehicle is being driven 10 can be caused, not wobbles or rattles. camp 31 the roller 29 and / or wheels 30th can on the cross member 15th be held.

Through the shaft 21 there is no need to reduce the flexural rigidity or stability of the cross member 15th come. Rather, by providing additional inner walls 32 in the shaft 21 the bending stiffness even compared to a hollow cross member 15th be enlarged. An inside wall 32 can for example be designed as a sheet metal that has a top 33 of the cross member with a bottom 34 of the cross member 15th through an interior of the cross member 15th through it connects.

A screen or display in the motor vehicle can therefore be larger than the installation space that is available on only one side of the cross member. In addition, it can be positioned at a freely selectable location in a vehicle cockpit during the construction of the motor vehicle. In addition, there is the possibility of making the display / screen variable in relation to the portion that is visible from the vehicle interior, that is to say that it can be retracted and extended and also stop or hold at an intermediate position.

The display, which can be extended in this way, now has additional space within the switchboard package or switchboard module and can therefore be positioned as required.

For this purpose, a support and assembly structure for retractable displays is proposed, in which a module cross member (MQT) or cross member is provided with an opening for the insertion of the retractable display. With the appropriate design, the MQT does not lose its strength or other properties. The MQT can also be used to attach the display including the kinematics (actuator unit) to a fixed vehicle structure. Thus, a package-optimized integration of MQT and display / kinematics can be achieved. There is a new possibility of positioning in the cockpit of a motor vehicle.

Overall, the examples show how an arrangement for an extendable display (screen) can be provided.
