Description

[0001] The invention relates to a device for moving an emblem under and over the hood of a motor vehicle, comprising the emblem being rotatably mounted at one end about its fixed vertical axis and pivotably mounted on a first pivot axis extending in the transverse direction, a cover movable in the vertical and transverse directions for closing and opening a recess in the hood through which the emblem can pivot when the recess is open, and a rotatable control disc with a transversely extending projection and a driver. The invention also relates to a motor vehicle with such a device.

[0002] GB 1 503 229 shows a device for retracting a retractable protrusion or a retractable emblem of a motor vehicle.

[0003] DE 23 56 761 shows a company logo designed as a radiator figure, which extends above the structure of a motor vehicle, preferably a radiator or a hood, and can be folded down and retracted by a force of a predetermined magnitude.

[0004] The invention is based on the objective of providing a device for a motor vehicle for relocating an emblem under a front compartment lid of the motor vehicle in a particularly theft-protected manner and for relocating the emblem again over the front compartment lid, as well as a motor vehicle with such a device.

[0005] The problem is solved by the subject matter of the independent patent claims. Advantageous embodiments of the invention are described by the dependent patent claims, the following description, and the figures.

[0006] A first aspect of the invention relates to a device for repositioning an emblem under and over a front hood of a motor vehicle, comprising the emblem being rotatably mounted at one end about its fixed vertical axis and pivotably mounted on a first pivot axis extending in the transverse direction, a cover that is repositionable in the vertical and transverse directions for closing and releasing a recess in the front hood, through which the emblem can pivot when the recess is released, and a rotatable control disc with a transversely extending projection and with a driver, wherein the emblem can be rotated and pivoted by the driver by rotating the control disc according to a first kinematic positive coupling of its rotation with its pivoting, and the cover can be repositioned by the projection when the control disc is rotated according to a second kinematic positive coupling.through which at least the pivoting of the emblem is coupled with the repositioning of the cover. This offers the advantage that only the control disc needs to be rotated for rotating and pivoting the emblem, as well as for repositioning the cover. Thus, three non-linear movements in different spatial directions of the emblem, which can be coordinated temporally or kinematically, can be realized together with the repositioning of the cover. Advantageously, for example, only one electric motor is needed to drive the control disc in order to reposition the emblem under and over a front panel and back again. Furthermore, this offers the advantage thatThe emblem can be stored or positioned in a particularly theft-proof manner under the cover and the hood. For example, when the vehicle is parked or shut off, the emblem can be moved under the hood, thus preventing it from being damaged, torn off, or stolen by unauthorized persons. The device is designed to be positioned or mounted on the hood of a vehicle. Specifically, when the device is mounted on the vehicle, its transverse direction runs in the transverse direction (y-direction) of the vehicle, and its vertical direction runs in the vertical direction (z-direction). The control disc is designed to ensure a transversely extending,The control disc is designed to be rotated or turned, particularly along its axis of rotation passing through the control disc. The control disc can be designed as a rotationally symmetrical or circular disc, or as a non-rotationally symmetrical disc. Essentially, the control disc extends into a plane spanned by the transverse and vertical directions. The raised portion, which can also be described as a profile or curvature, extends from this plane transversely towards the emblem. The driver can also extend from this plane or from the control disc transversely towards the emblem and can be designed as a pin, bolt, or cylinder whose central axis extends transversely. The cover, particularly when the device is mounted on the vehicle, can be designed as a strip-like element extending in the longitudinal or x-direction of the vehicle, which is configured toThe recess in the hood is to be closed or filled by the cover in a closing position or arrangement of the cover. When the emblem is positioned over the hood, extended, or swung out, it may have a rod-shaped base extending vertically from the hood, to which a star extending laterally is attached. In particular, when the emblem is positioned on the vehicle, its longitudinal dimension or thickness is smaller than its vertical and transverse dimensions. Specifically, the emblem has a larger transverse dimension, at least partially, than the width and transverse extent of the recess. To move the emblem under the hood through the recess, it must be rotated about its vertical axis.in particular by 90 degrees of arc, so that it fits through the recess in terms of width and can be pivoted around the first pivot axis, which extends in the transverse direction, for repositioning under the front cover. The body-fixed vertical axis means that the vertical axis pivots along with the emblem when it is pivoted, whereby the first pivot axis, around which the emblem is pivoted through the released recess, remains fixed to the vehicle initially or unchanged, or remains fixed to the vehicle when mounted on the vehicle. According to the first kinematic coupling, the pivoting and rotation of the emblem are coupled; the rotation cannot occur independently of the pivoting. In particular, it is provided that the emblem rotates around its vertical axis during the pivoting around the first pivot axis, specifically that the emblem is rotated 90 degrees around the vertical axis.before it is pivoted 90 degrees around the first pivot axis. This ensures that when the emblem reaches the recess during pivoting around the first pivot axis, it is in such a rotational position that it fits through the recess.

[0007] The first aspect of the invention also includes embodiments or further developments that result in additional advantages.

[0008] A further development of the device provides that by rotating the driver, a rail engaged with it and pivotably mounted at one end about the first pivot axis can be pivoted, which at the other end is connected to a first end of a control arm pivotally mounted about a second body-fixed pivot axis of the rail and guided along a control cam, via which, by means of a connecting rod articulated at its second end, a cantilever radially spaced from the body-fixed vertical axis of the emblem, rotationally fixed to the emblem about the vertical axis and articulated to the connecting rod, can be moved in conjunction with the control cam, so that the emblem is rotatable and pivotable according to the first kinematic positive coupling.In other words, when the control disc is rotated, the driver, which is connected to it (in a rotationally fixed manner) and engages with the rail, is moved, causing the rail, which is pivotable at one end about the first pivot axis, to rotate about this axis. The rail has a guide facing the driver, into which the driver engages. This guide allows translational movement of the driver relative to the rail between its two ends, but prevents relative movement of the driver perpendicular to the first pivot axis and the translational movement, thus allowing the driver to rotate the rail about its pivot axis. Alternatively, the rail is designed to pivot about a different pivot axis than the first, which can, however, run parallel to the first pivot axis.At the other end, the rail is connected to the control arm, which is in particular strip-shaped or elongated and can rotate relative to the rail about the second pivot axis, which is fixed to both the rail and the control arm. Spaced apart from its first end, where it is connected to the rail, the control arm has a pivoted connection to a connecting rod at its second end. "Pivoted" here means that the connecting rod can rotate relative to the control arm about at least one axis, in particular about two axes, and most preferably about three axes. The connecting rod is designed as a rod-shaped or elongated element and is connected to the boom at its end spaced apart from the control arm. The connection point of the connecting rod with the boom has, on the one hand, a lever arm to the vertical axis of the emblem and, on the other hand, a lever arm to the first pivot axis.The boom is rigidly connected to the emblem, particularly to its base, preventing rotation and translation. When the control arm is guided along the control cam, the connecting rod rotates the emblem about its vertical axis and pivots it about the first pivot axis, thus coupling the rotation and pivoting according to the first kinematic positive coupling. This offers the advantage that the emblem can be rotated and pivoted, particularly pivoted under the front cover, solely by the rotation of the control disc or by moving the drive mechanism.

[0009] A further development of the device provides that the control arm has a rotating guide roller at its second end, which, by rolling along the control cam, allows or guides the control arm along the cam. The control cam can be designed to be at least partially mounted or attached to the front cover. The guide roller is arranged at the same end of the control arm where the control arm is pivotally connected to the connecting rod. Rolling the guide roller along the control cam particularly advantageously ensures that the control arm, and especially the end of the connecting rod connected to it, follows the control cam. This allows the distance between this end of the connecting rod and the arm to be varied via the connecting rod, thereby realizing the first positive coupling.

[0010] A further development of the device provides that the device has a push rod which is displaceable in the transverse direction by means of the elevation, at least one ramp and at least one pivot arm which is rotatably connected at one end, in particular about a vertical axis, to the cover and at the other end rotatably about a vertical axis and displaceably in the vertical direction to its bearing and which has a guide pin which extends in a vertical direction, in particular in a vertical direction, which is at least indirectly connected to the push rod and by which, depending on a displacement of the push rod, the pivot arm is displaceable in the vertical direction along the at least one ramp and rotatable about its bearing according to the second kinematic positive coupling.In other words, when the control disc is rotated by means of the raised section, the push rod is moved laterally. The push rod, in turn, lowers the cover or the pivot arm vertically via the pivot arm, guided along the ramp, and the pivot arm is rotated around its bearing. This first moves the cover vertically and then laterally, releasing the recess for the emblem to pivot from its extended position to its position below the front cover. The push rod can be connected to the pivot arm via a connecting piece into which the guide pin engages. Thus, when the push rod is moved, the pivot arm is moved via the connecting piece and the guide pin.The drive element and the raised section are offset from each other by a predetermined angle of rotation around the control disc's axis of rotation, thus realizing the second kinematic positive coupling. This means the recess is released before the emblem pivots through it. This second kinematic positive coupling ensures that the recess is released by the cover before the emblem reaches the level of the recess or the front panel cover during its pivoting movement—that is, both when pivoting or moving under the front panel cover and when pivoting or moving over it. Before the cover located in the recess can be moved laterally, it must be moved at least partially downwards relative to the vertical direction.To convert the lateral movement caused by the push rod into an upward movement, the device has at least one ramp along which, or along whose slope, the swivel arm slides downwards relative to the upward direction when moving laterally. This has the advantage that the recess is clear before the emblem is swung through it.

[0011] A further development of the device provides that the control disc for repositioning the emblem can be driven by an electric motor within the device. In other words, the device is to include an electric motor for driving the control disc. This offers the advantage that the control disc can be driven electrically and does not need to be operated manually. According to the invention, the electric motor can be coupled to a control unit of the motor vehicle, so that the emblem is moved, for example, under the hood when a traction motor is switched off or when the motor vehicle is locked, and / or when the traction motor is started or when the motor vehicle is unlocked, the emblem is moved over the hood.

[0012] To move the emblem from its position below the front panel cover to a position above the front panel cover, the control disc must be turned in the opposite direction to that used for pivoting, and the described movements are carried out in reverse order.

[0013] A second aspect of the invention relates to a motor vehicle with a device, in particular according to the first aspect of the invention. Advantages and advantageous developments of the first aspect of the invention are to be regarded as advantages and advantageous developments of the second aspect of the invention, and vice versa.

[0014] The vehicle is designed, for example, as a motor vehicle, in particular as a passenger car or as a commercial vehicle. The vehicle can be designed as an electric vehicle or hybrid vehicle, or as a motor vehicle powered exclusively by an internal combustion engine. The vehicle has a front compartment lid with the recess described in connection with the device.

[0017] In the figures, identical or functionally equivalent elements are provided with the same reference symbols.

[0018] Fig. Figure 1 shows a schematic perspective view of a device 10, partially arranged under a transparently depicted front cover 14 with a fully swiveled emblem 12. The emblem 12 is rotatable about its fixed vertical axis 16 and pivotable about a first pivot axis 18. Fig. Figure 1 shows the emblem 12 in a starting position from which it can be pivoted and stowed under the front compartment cover 14 or moved beneath it. For this relocation, the device 10 has a cover 20 for closing and releasing the recess 22 in the front compartment cover 14. The device 10 has a control disk 24 on which a driver 26 is arranged extending transversely. The driver 26 engages with a rail 28, which is pivotable at one end about a pivot axis, in particular about the first pivot axis 18, by the driver 26. At the other end, the rail 28 is connected to a control arm 34, the control arm 34 being rotatably mounted to the rail 28 at its first end relative to the rail 28 about a fixed second pivot axis 30.At its second end, which is spaced apart from the first end or from the rail 28, the pivot arm 34 can be guided or moved along a control cam 32. At its second end, the control arm 34 can be pivotally connected to one end of a connecting rod 36.

[0019] Fig. Figure 2 shows another schematic, perspective view of the device 10 from a different angle than in Figure 2. Fig. 1, under the transparently depicted front compartment cover 14 with the fully swung-out emblem 12, i.e. with the emblem 12 in the same position as in Fig. 1. As in Fig. As shown in Figure 2, the control arm 34 can be pivotally connected to the connecting rod 36 at its second end and can have a scanning roller 40 rotatable about a transversely extending axis of rotation. The scanning roller 40 can be designed to roll along the control cam 32. The device 10 can be rotatably mounted about its respective bearings 50 about a respective vertical axis 54 extending in the vertical direction. A second pivot arm 48, in Fig. 2 shown in the foreground, can only serve as a support for a first swivel arm 48 (in Fig. (2 shown in the background). A ramp 44 can be provided for each of the two pivot arms 48. At least one pivot arm 48 can have a guide pin 46, via which the at least one pivot arm 48 can be moved laterally by a push rod 42 and thus rotated about its bearing 50 and moved along a ramp 44 in the vertical direction. At least one bearing 50 can have a tension and torsion spring 52, by means of which the emblem 12 can be moved back from the pivoted state to the pivoted state. In other words, the spring 52 is tensioned when the emblem is pivoted and, after it has fully pivoted, pushes the cover 20 back into the recess 22. Finally, after pivoting in and out, the cover 20 is moved back into the recess 22 and closes it.

[0020] Fig. Figure 3 shows a schematic, perspective view of the device 10, partially arranged under the transparently shown front cover 14, starting from the state of the emblem 12 in Fig. 1 and Fig. 2 swiveled and rotated emblem 12. Starting from Fig. 1 and Fig. 2 has moved into Fig. 3. The control disc 24, together with the driver 26, is rotated about its axis of rotation. This allows the rail 28, which may be engaged with the driver 26, to rotate about the first pivot axis 18. The rotation of the rail 28 allows the control arm 34, which is rotatably mounted about the body-fixed second pivot axis 30 and connected to the rail 28, to move. The control arm 34 follows the control cam 32 with its second end via its sensing roller 40, with the sensing roller 40 rolling along the control cam 32. The connecting rod 36 can be connected at one end to the second end of the control arm 34 and at the other end to a cantilever 38. As in Fig. As shown in Figure 3, the connecting rod 36 can be pivotally mounted at each of its ends, i.e., rotatably mounted at each of its ends about two spatial directions. The arm 38 can be fixed to the emblem 12 in a rotationally fixed or rotationally fixed and translationally fixed manner and can have a lever arm both to the body-fixed vertical axis or rotational axis of the emblem and to the first pivot axis 18. By the scanning roller 40 moving away from or scanning the control cam 32, the connecting rod 36 can rotate the emblem 12 about its body-fixed vertical axis 16, as shown in Figure 3. Fig. 3 shown, rotate and pivot about the first pivot axis 18. In the Fig. In the pivot position of the emblem shown in Figure 3, the recess 22 may still be partially closed by the cover 20. The raised section may already have partially pressed into the push rod 42. Fig. 3, so that the cover 20 is lowered vertically and shifted laterally.

[0021] Fig. Figure 4 shows the device 10 or the emblem 12 in the same state as in Fig. 3, just from a different perspective. As in Fig. As shown in section 4, the two swivel arms 48 can be used in the Fig. 4 and Fig. In the pivot position of emblem 12 shown in Figure 3, the pivoting position is already partially moved by a displacement of the push rod 42 through the elevation of the control disc 24 along the two ramps 44. Due to the inclination of the ramps 44, the pivoting arms 48 move both vertically and laterally. In the Fig. In the position shown in Figure 4 of the swivel arms 48 along the ramps 44, the cover 20 can still close the recess 22.

[0022] Fig. Figure 5 shows a schematic perspective view of the device 10, partially arranged under the transparently shown front cover 14 with the emblem 12 partially pivoted and rotated, and the recess 22 released. As in Fig. As shown in Figure 5, the control disc 24 may have rotated further compared to its respective position in the previous figures. As in Fig. As shown in Figure 5, the control arm 34 with its scanning roller 40 has moved further along the control curve 32. The rotation and pivoting of the emblem 12 are coupled to the extension arm 38 via the connecting rod 36 by means of a first kinematic positive coupling. As shown in Fig. As shown in Figure 5, with the control disc 24 or the scanning roller 40 in the position shown along the control curve 32, the emblem 12 may already be partially swung through the recess 22.

[0023] Fig. Figure 6 shows the device 10 or the emblem 12 in the same position as in Fig. 5 shown, but from a different perspective. As in Fig. As shown in Figure 6, the two pivot arms 48, in the pivot position of the emblem 12 shown, can have completely slid down their respective ramps 44 or their respective inclines and locked into place under their respective ramps 44, and thus be shifted downwards in the vertical direction compared to their position shown in the Fig. 1 to 4. The swivel arms 48 can be guided vertically along their bearings 50. The in Fig. The rear swivel arm 48 can be rotated about its bearing 50 and guided along its ramp 44 by means of a connecting piece connected to the push rod 42 via its guide pin 46. The compression and torsion spring 52 can be in the Fig. The situation shown in section 6 may be further stretched compared to its position shown in the Fig. 1 to 4. The cover 20 can be rotatably mounted to each end of a swivel arm 48 spaced apart from the respective bearing 50, in particular rotatably mounted about an upward direction. As in Fig. As shown in Figure 6, the cover 20 can be located under the front compartment cover.

[0024] Fig. Figure 7 shows a schematic, perspective view of the device 10, partially arranged under the transparently shown front cover 14 with the emblem 12 mostly pivoted and rotated inwards and the recess 22 released. Compared with Fig. 5 and Fig. 6 is the emblem 12 in Fig. 7 further pivoted about the first pivot axis 18. For this purpose, as a result of a further rotation of the control disk 24, the scanning roller or the second end of the control arm 34 can be guided further along the control cam 32, in particular by the scanning roller 40, compared to the previous figure. As in Fig. As shown in Figure 7, the elevation of the control disc 24 can be designed such that it holds the push rod 42 pressed until the emblem 12 is fully pivoted in, so that the recess 22 remains open through the cover 20.

[0025] Fig. Figure 8 shows a schematic, perspective view of the device 10, arranged under the transparently shown front cover 14 with the emblem 12 fully pivoted and rotated, and the recess 22 closed again. As in Fig. As shown in figure 8, the control disc 24 can be used when the emblem is fully swung in, i.e., when it is in Fig.The rotation angle or pivot angle of the emblem 12 shown in Figure 8 is again recessed, i.e., in such a way that the protrusion no longer rests against the control rod 42, so that the cover 20 together with the pivot arms 48 and the push rod 42 is turned and / or pushed back again as a result of the previously pre-tensioned compression and torsion spring 52, so that the cover 20 closes the recess 22 again and the emblem 12 is completely stowed or arranged under the front cover 14.
