Description

Technical Field

[0001] This invention relates to an assembly for a vehicle, comprising a crossbeam, a holding device, and a plate-shaped instrument, particularly a display, wherein the crossbeam is configured to connect to two columns opposite each other relative to the xz plane of the vehicle, the holding device is connected to the crossbeam and extends radially from the crossbeam and includes two supports spaced apart from each other in the y-direction, the holding device having connectors at its ends, and the plate-shaped instrument being connected to the connectors of the holding device at a position spaced apart from the upper end of the plate-shaped instrument, the plate-shaped instrument being held such that the operating surface of the plate-shaped instrument points in the x-direction toward the passenger compartment of the vehicle. Background Technology

[0002] Increasingly large display and operating units, or monitors, are installed in motor vehicles. These display and operating units are panel-type instruments. In many cases, the panel-type instrument serves as a central display located approximately in the center of the instrument panel area. These displays point their display or operating surfaces towards the passenger compartment of the vehicle so that the driver and front passenger can read the information on them. In most cases, such displays are also provided as input units. In this case, the display is touch-sensitive. Due to the size of the display, the limited space available in many cases, and also for comfort and ergonomic reasons, such displays are not always integrated into the instrument panel but rather protrude from the upper end of the instrument panel. Designs in which this protruding display can be lowered in the usage position are also known.

[0003] This type of plate-shaped instrument, especially when it protrudes fully or partially from the upper end of the dashboard, should be held in such a secure manner that it does not increase the risk of injury to vehicle occupants in the event of an accident. To this end, document EP 3 045 340 B1 suggests arranging such a display on a support element extending relative to the back of the display. This support element is designed to be angled. The display is connected to an arm extending along the height direction (yz direction). On the outer side relative to this angled shape, the two arms are connected by a metal connecting plate made of leaf spring material. The support element is designed such that when the load acting on the upper region of the display exceeds a certain force, the support element breaks and the display folds in the direction of travel. For this type of plate-shaped instrument, which protrudes from the dashboard surface in at least one section, it is also necessary to ensure that the holding device can withstand loads without damage, such as when a person, for example, grasps the upper side of the display to help lift it, using the upper side as a handle and pulling themselves upwards, subjecting the dashboard to such loads. This type of load, also known as misuse, must not result in damage or destruction of the holding device.

[0004] A mounting device for a display device inside a car is known from document DE 10 2016 004 156 A1. In this mounting device, the display device is located in front of the steering wheel. When the steering column adjusts upwards due to an accident, the display device is released from its mounting device. Because the steering column moves, the display device is released from the mounting device and, since it is no longer connected to the support, there is no longer a risk of injury.

[0005] An additional mounting device for a display in a motor vehicle is known from document JP 2008-290508 A. This mounting device comprises two separate, spaced-apart brackets connected at one end to an instrument panel crossbeam. The mounting device protrudes upward from the instrument panel crossbeam in the z-direction. This is considered necessary to provide sufficient energy absorption within the available mounting space. In addition to the arm extending in the z-direction and connected at one end to the crossbeam, the bracket also includes an angled V-shaped support member thereon, thus this section of the bracket is designed as N-shaped in a side view. An audio unit integrated into the dashboard is connected to a shorter, parallel support arm, which also extends in the z-direction. Due to this design of the bracket, the distance between the two arms extending in the z-direction is reduced when a force is applied to the audio unit in the x-direction. The associated deformation work absorbs energy. To maintain the vertical orientation of the connected audio unit even under deformation, a rated bend is added between the connection of the arm of the bracket carrying the audio unit and the inclined connecting plate through material weakening. This bracket is used to hold the audio system that does not protrude from the top of the dashboard. Therefore, the bracket does not need to meet the requirements for displays that protrude beyond the dashboard surface.

[0006] Document JP 2013-082 362 A discloses a holding device for a plate-type instrument, comprising one or more supports. These supports are designed to consist of two parts and are interconnected by a threaded friction fit. The support connected to the crossbeam includes an elongated hole in which the threaded part is guided, allowing the two parts to slide relative to each other. Upon collision, the supports are pushed together due to the force applied.

[0007] Document DE 10 2019 113 312 A1 discloses a bracket for the interior of a motor vehicle.

[0008] Document US 2004 / 0212220 A1 discloses an energy-absorbing bracket that includes additional reinforcing elements within its double-shell structure and still meets energy absorption requirements in the event of a collision.

[0009] Document US 9,409,606 B2 discloses a beam that is weakened by elongated holes so that it can bend in the event of a collision.

[0010] Document EP 3 045 340 B1 discloses a holding device for plate-shaped instruments, wherein the support of the holding device is designed as a metal plate with a meandering nominal bend.

[0011] According to regulations governing the holding devices for plate-shaped instruments such as displays, these devices must be designed to be sufficiently flexible to avoid exceeding the maximum permissible acceleration acting on the occupant's head. On the other hand, these devices must also meet misuse requirements without undergoing plastic deformation or damage. The misuse force is assumed to be approximately 300 N, with particular emphasis on forces along the x-direction (both directions) and the z-direction (pointing downwards). Summary of the Invention

[0012] In light of the prior art described above, the technical problem to be solved by the present invention is to improve the aforementioned type of component for a vehicle so that the component not only meets the requirements of passenger safety, but is also suitable for carrying panel-type instruments, such as displays, which are arranged at least in a section beyond the upper side of the dashboard, and thus also meet the requirements for misuse, and can be installed even if the installation conditions are constrained.

[0013] The technical problem described herein is solved by a component of the aforementioned type, wherein two supports are designed in a semi-shell configuration, the semi-shells being arranged with their open sides pointing in the y-direction, wherein two arms of the supports designed as semi-shells are arranged in the xy-plane and a connecting plate connecting these two arms is arranged in the yz-plane, and the supports each have at least one nominal bend provided by the geometry of the supports between their two connection points, the supports bending in the z-direction and / or y-direction at the nominal bend under load (in the x-direction).

[0014] The directional orientation and planar orientation (x, y, z) used within the scope of this implementation are those commonly used in vehicles. Therefore, the x-direction corresponds to the longitudinal extension of the vehicle, the y-direction corresponds to the lateral direction relative to the x-direction, and the z-direction corresponds to the vertical direction. The planes (yz plane and xz plane) relating to the spatial position of the arms of the two winglets should not be strictly interpreted geometrically. Rather, the spatial position can deviate from the strict geometric plane as long as the projection of the actual spatial position (IST-Raumlage) onto the strict geometric plane maps most of the actual spatial position. The deviation is preferably no more than ±40°. The same applies to directional data.

[0015] The component has two supports designed as half-shells. These two half-shells are arranged in the component such that the open sides of the half-shells point in the y-direction. According to one embodiment, the open sides of the half-shells are arranged to point towards each other. Each half-shell has two arms located in the xy-plane and a connecting plate connecting the two arms. The connecting plate is arranged in the yz-plane.

[0016] To ensure that the display can be adjusted by bending at a defined point when the acceleration acting on it exceeds a certain level, the bracket has at least one rated bend in this condition. This rated bend is designed such that when a shear load (load direction along the x-direction) caused by an accident acts on the upper end of the display, the bracket bends in the z-direction and / or y-direction. The bending direction of the bracket is therefore laterally extended relative to the acceleration acting on it.

[0017] The bracket is connected to the crossbeam by extending from it along the x-direction. Therefore, the crossbeam acts as a support, providing stability under all conditions and resisting the acceleration acting on the display, which is absorbed by bending, thus leading to the necessary adjustment and energy absorption of the display. The upper end of the panel instrument is spaced apart from the upper end of the bracket along the z-direction. If the display protrudes as far as possible from the top of the dashboard in terms of its height, the bracket will be connected to the lower area of ​​the display. The acceleration acting on the display causes a bending moment in the bracket, so that when a force is applied accordingly, the bracket bends at a predetermined rated bending point, which is typically introduced by a head impact of a vehicle occupant in an accident. The rated bending point is provided by the geometry of the bracket in the area of ​​the rated bending point. This can be adjusted by the height of the connecting plate along the z-direction when the bracket is to bend along the z-direction, i.e., about a bending axis extending along the y-direction. Here, the bending direction is also predetermined by the geometry. Bending should occur upwards along the z-direction. Therefore, such a bracket has a concave shape in the region of the nominal bend in terms of its upper geometry, wherein the bending axis extending in the y-direction is arranged in the region of the apex of the shape. Typically, the extension direction of the lower arm in its xy-plane follows the extension direction of the upper arm, at least in the region of the nominal bend. Advantageously, this geometry for providing the nominal bend is pre-designed to respond to a corresponding acceleration or force acting thereon in the x-direction, but not to respond to misuse, such as when a occupant grasps the upper edge of the display to straighten up, and a pulling force is applied thereon.

[0018] To address the requirement of providing flexibility even when acceleration or force acts on the plate-type instrument during an accident and is coupled to the support in terms of height, the support additionally has a rated bend. At this rated bend, the support section closer to the display than the rated bend bends or turns along the y-direction relative to the support section on the other side of the rated bend. This is achieved by having offset flexures in both supports along the y-direction, whereby the two support sections separated by the flexures are offset relative to each other along the y-direction when their longitudinal extensions are aligned, and the offset support sections by the flexures do not overlap along the y-direction when aligned. Under loads acting on such a support along the x-direction, the flexures function as hinges. The axis of the flexures typically extends along the z-direction. In this design, the support section carrying the connector can be tilted opposite to the offset direction of the flexures, thus having a preset value for activating the rated bend. Depending on the support design, an tilt angle between 16° and 18° relative to the geometric x-direction is sufficient. The other support section on the beam connection side does not necessarily need to have such a pre-design. The flexural portion is preferably located outside the center of the longitudinal extension of the support, more precisely, offset towards the connection between the support and the beam. In this case, the support section carrying the plate-type instrument is longer and acts with a correspondingly greater lever at the rated bend. Therefore, the response at the rated bend can also be affected by the length of this support section.

[0019] An advantage in the design of the support is that the section of the support before the actual connection with the crossbeam has a higher bending stiffness than the adjacent section of the support with at least one rated bending point. Therefore, the bending support moves from the crossbeam toward the rated bending point.

[0020] The bracket is designed as a semi-shell, with angled arms formed on the connecting plate, allowing for customization to meet different requirements. Stiffness or bending performance can be easily influenced by adjusting the arm height or width. Other measures to affect bending performance, such as different material thicknesses or different metal structures, are also possible. One or more openings can also be considered on the connecting plate connecting the arms.

[0021] It should also be emphasized that this holding device only needs to be connected to the instrument panel crossbeam. This is also the case in the preferred embodiment. Therefore, this holding device is suitable for components of the type described above, in which case only a relatively small installation space can be used. Attached Figure Description

[0027] Figure 5 The accompanying figure shows a perspective view of the support structure viewed from different directions. Detailed Implementation

[0028] Component 1 for vehicles includes an instrument panel crossbeam 2. Figure 1 Only a portion of the instrument's crossbeam is shown in the figure. For simplicity, the crossbeam 2 is depicted as a tube in the figure. The crossbeam may also have other cross-sectional geometries, or may consist, for example, of two housings to form the cavity profile required to construct such a crossbeam. In addition to the crossbeam 2, component 1 also includes a holding device 3. The holding device has two supports 4, 4.1. These two supports 4, 4.1 are mirror-symmetrical with respect to the yz plane. The supports 4, 4.1 are connected to the crossbeam 2 at one end, more precisely, by welding. The welded connection follows the outline of the supports 4, 4.1 on the outer side. Both the crossbeam 2 and the supports 4, 4.1 are made of steel. The supports 4, 4.1 are spaced apart from each other along the y-direction. At the ends of the supports opposite to the crossbeam 2, the supports 4, 4.1 of the holding device 3 are connected to the back of the display 5 of the exemplary plate-type instrument. Figure 1 As can be seen, the brackets 4 and 4.1 are connected to the display 5 at a small distance from the lower terminal on the lower half of the display. The display 5 is thus eccentrically connected to the holding device 3 along the height direction (z direction). The distance between the brackets 4 and 4.1 and the upper terminal 6 of the display 5 along the z direction is significantly greater than the distance between the brackets 4 and 4.1 and the lower terminal 7 of the display.

[0029] As explained below with reference to bracket 4, brackets 4 and 4.1 have a rated bending point so that, in the event of acceleration, such as from a head impact, the upper end 6 of the display 5 bends towards the crossbeam 2 to avoid or reduce the risk of injury. If a collision from the passenger compartment toward the operating surface of the display acts as a smaller tilting load, thus coupling a bending moment into the corresponding brackets 4 and 4.1, but acts as a larger load along the x-direction at the height of the display 5, then brackets 4 and 4.1 bend, thereby reducing the distance between the display 5 and the crossbeam 2. Brackets 4 and 4.1 are therefore used to absorb energy and are designed not to break under bending conditions.

[0030] The brackets 4 and 4.1 are spaced relatively far apart from each other along the y-direction relative to the extension of the display 5 in that direction, and are connected to the display only at a small distance from the side terminal of the display 5 pointing along the y-direction. The brackets 4 and 4.1 protrude from the crossbeam 2 along the x-direction.

[0031] The following description of support 4 also applies to support 4.1, which is designed to be mirror-symmetrical with respect to support 4.

[0032] The bracket 4 is designed as a semi-shell and has an upper arm 8 and a lower arm 9 spaced apart from the upper arm along the z-direction. These two arms 8 and 9 are connected to each other by a connecting plate 10. In the illustrated embodiment, there is no opening in the connecting plate 10. The two arms 8 and 9 are located in the xy-plane. The connecting plate 10 connecting the arms 8 and 9 is located in the yz-plane. The arms 8 and 9 abut against the connecting plate 10 in a radial manner. This radius is a result of the manufacturing process of the bracket 4, which is manufactured as a bent piece made of sheet steel. The display 5 is connected to the connecting side 10, where the arms 8 and 9, placed horizontally, are widened at their end sections (see...). Figure 3 and Figure 4 This allows the arm to be fitted with connectors, enabling the display 5 to be attached to the connectors. In the illustrated embodiment, these connectors are circular openings 12, 12.1 through which bolt fasteners (not shown) pass. Figure 5 It can be seen that the clamping nut 13 is connected to the lower side of the relevant widened part of the lower arm 9, and the bolt fastener can be fixed in the internal thread of the clamping nut, wherein the bolt fastener passes through the opening 12 of the upper arm 8 and the connector 14 of the display 5 with its shank.

[0033] The geometry of the bracket 4 is designed such that it has a first rated bend S1. When an acceleration caused by an accident acts on the upper terminal 6 of the display 5, the bracket 4 bends along the z-direction through this first rated bend, as shown in... Figure 2As indicated by the arrow. The rated bend S1 is provided by a concave section 15 of the extension of the upper arm 8. Figure 2 In the side view, the concave design can be seen from the spatial position of the upper arm 8, which changes along the x-direction. In the case of bending of the bracket 4, the crossbeam 2, located after the rated bending point S1 along the collision direction in the x-direction, functions as a support. In the bracket section providing the crossbeam connection 16, the arms 8 and 9 have a relatively large width (see...). Figure 3 and Figure 4 The width decreases along the curved profile toward the nominal bend S1. Due to the increased width of the arms 8 and 9, the joint surface for connecting the bracket 4 to the crossbeam 2 is enlarged. Simultaneously, this also increases the bending stiffness of the bracket 4 in the region of its crossbeam connection 16, defining the nominal bend S1, where the bracket section on the connecting side bends or turns relative to another bracket section to absorb energy. In the illustrated embodiment, the concave section 15 in the upper arm 8 of the bracket 4 is provided by an inclined transition of the bracket 4 in its section having the crossbeam connection 16 relative to the bracket section having the connecting side 11, with the nominal bend S1 located at the apex of the concave section. Figure 2 As can be seen from the side view, the two support sections are arranged in a V-shape relative to each other, thereby defining the upward bending direction along the z-direction. In this respect, the geometry of the support 4 provides a preset for defining the bending direction (z-direction). The bending axis of the nominal bend S1 extends along the y-direction.

[0034] from Figure 3 As can be seen in the top view, the bracket 4 is bent into an S-shape in the xy-plane, thus forming a flexure. The misalignment of this flexure points in the y-direction. The bracket segments misaligned relative to each other by the flexure do not overlap when aligned (in the x-direction). Through this geometry, a nominal bend S2 is provided in the bracket 4, in which the bracket 4 bends towards the crossbeam 2 in the y-direction when a force is applied accordingly to the display 5 in the x-direction. The bending axis of this nominal bend S2 extends in the z-direction.

[0035] The support section on the beam connection side is adjacent to the beam 2 at a right angle in the yz plane. The support section on the connection side, separated from this support section by the rated bend S2, is inclined relative to the connection direction, more specifically, in the illustrated embodiment, at an angle α of approximately 14°. This inclination, set against the misalignment direction of the flexure, serves as a preset to activate the rated bend S2.

[0036] The support 4 therefore has rated bends S1 and S2, by means of which the support can be bent in two directions to absorb energy.

[0037] For bracket 4, the height of connecting plate 10 decreases in the transition to the end section widened about its arms 8 and 9 (see especially). Figure 2 In the illustrated embodiment, this height reduction is achieved only in the region of the upper arm 8 of the support 4 in the form of a flexure. This flexure, designed over a short distance, provides reinforcement, thereby transmitting the force coupled to the support 4 via the display 5 to the rated bends S1 and S2. In the region of the beam connection 16, this crank-style flexure also has the effect of moving the actual support toward the rated bends S1 and S2.

[0038] The bracket 4, divided into two bracket sections by the two rated bends S1 and S2, is designed such that the bracket section with the crossbeam connection 16 is the shorter bracket section. Therefore, the lever applied to the rated bends S1 and S2 by the bracket section on the instrument connection side is correspondingly larger.

[0039] In this design, the force required for bending can be adjusted according to the specific application related to the vehicle, for example, by adjusting the width of the arms 8, 9, the preset height provided by the flexure, or the height of the connecting plate 10, so as to only account for the major impact. Therefore, the brackets 4, 4.1 of the retaining device 3 can be adjusted very precisely to absorb the force in the event of an accident. Using two brackets 4, 4.1 also allows them to be designed differently in terms of crash performance; for example, because the driver-side bracket is located behind the steering wheel in the x-direction, a different crash performance is required on the display side than on the passenger-side terminal of the display.

[0040] The brackets 4 and 4.1 of component 1 have a relatively small height on the instrument connection side. Combined with the connection of brackets 4 and 4.1 in the area of ​​the lower terminal 7 of display 5, a relatively large lever is provided, through which the display is adjusted in the case of acceleration load caused by an accident in the area of ​​the upper terminal 6 of display 5.

[0041] The above design of the brackets 4 and 4.1 of the holding device 3 clearly shows that the tension acting on the upper terminal 6 of the display 5 will not cause the brackets 4 and 4.1 to deform, or at least will not be deformed by such force, which would be coupled into the display 5 if the user mistakenly uses the upper terminal 6 of the display 5 as a handle to straighten up.

[0042] In the embodiment described with reference to the accompanying drawings, the bracket is made of steel plate. Of course, other materials, such as aluminum alloy, can be used as alternatives. Non-metallic materials can also be used.

[0043] The present invention has been described with reference to the accompanying drawings and embodiments. Many other designs will be apparent to those skilled in the art without departing from the scope of the effective claims, and need not be described in detail within the scope of the embodiments.
