Description

[0001] The invention relates to a device for holding a license plate. The invention relates to a motor vehicle.

[0002] Holders for license plates are known from the publications DE 10 2007 047 674 A1, DE 10 2022 118 385 A1, JP 2021 - 146 764 A, DE 100 33 500 A1, AT 390 766 B and EP 3 592 609 B1.

[0003] Motor vehicles must meet legal requirements for pedestrian protection. This includes both the impact scenario of a head collision with the hood and the impact scenario of a leg collision with the front of the vehicle. The latter scenario simulates a pedestrian impact with the front of a vehicle in a 40 km / h accident. A leg impactor can be used to test the vehicle structure in this scenario. A leg impactor – called a Flexible Pedestrian Legform Impactor – is used specifically for this purpose. It can replicate the structure of a human leg as a substitute for a standard impactor.

[0004] The legal requirement includes, for example, compliance with biomechanical limits. The applicant complies with the currently applicable legal regulations and / or implements safety measures to protect the safety of road users to the best of their ability. Nevertheless, the applicant strives to further develop the protection of road users.

[0005] In appropriate crash tests, the knee ligament strain, cruciate ligament strain, and bending moments at the lower leg can be evaluated using a so-called FlexPLI for leg impact, for example, in the event of a frontal collision involving the leg. Due to legal requirements in the USA, the EU, and Germany at the time of registration or priority, the vehicle structure must be designed with a correspondingly soft profile.

[0006] As vehicles evolve towards autonomous driving, a multitude of sensors can be integrated, primarily in the front of the vehicle. These sensors, such as radars, cameras, and optical sensors, all require a defined installation space and are then visible to the customer. From a vehicle design perspective, such sensors are like foreign objects and are perceived as disruptive.

[0007] The purpose of the invention is to improve the design of a vehicle front and passenger protection.

[0008] The problem is solved in particular by a motor vehicle with the features of claim 1. Further features and details of the invention will become apparent from the dependent claims, the description, and the drawings. Features and details described in connection with the motor vehicle according to the invention also apply in connection with the device according to the invention for holding a license plate. The reverse is also true, so that the disclosure of the individual aspects of the invention always makes, or can make, reciprocal references.

[0009] According to one aspect, the problem is solved in particular by a motor vehicle with the features of claim 1.

[0010] A device for holding a license plate on a motor vehicle is provided. The device is designed to move the license plate. The device consists of at least two parts. A first part has a base plate. A second part has a license plate holder. The base plate is designed and configured to guide the license plate holder translationally, in particular upwards and downwards, and in other embodiments also to the right or left. The base plate is designed to be connected to the motor vehicle. The motor vehicle has a defined installation space for a sensor. The device is designed and configured to expose a sensor concealed behind the license plate when the license plate holder is in a certain position within the defined installation space.

[0011] A device for holding a license plate on a motor vehicle is provided, which may be designed to hold and move the license plate on the vehicle in order to expose a sensor concealed behind the license plate in a certain position of the license plate holder. The device for moving the license plate is specifically configured to move it back and forth in a vertical direction. In other embodiments, the device for moving the license plate may be specifically configured to move it back and forth in a horizontal direction. The device consists, in particular, of at least two parts: the base plate and the license plate holder.

[0012] The base plate serves primarily as the lower (in the sense of rear) base (when viewed from the front of the vehicle, or at the license plate, in a closed configuration) for the device and is specifically connected to the motor vehicle. In some embodiments, the connection can be direct; in others, it can be made via intermediate devices, such as a bumper. In other words, the base plate has a translational guiding property, meaning it is able to support the license plate holder in a vertical or horizontal direction in such a way that it can be moved back and forth as needed, for example, when the sensor is to be activated. The base plate can be attached to the motor vehicle, for example, by screws, clips, or adhesive.

[0013] The license plate holder can be positioned as the upper (i.e., front) part of the device (when viewed from the front or the license plate in a closed position) and serves, in particular, to hold the license plate and move it vertically or horizontally. It can also be movably mounted on the base plate. "Translational guidance" refers to the ability of a component or part to move back and forth in a specific direction (here: vertically).

[0014] The device for holding a license plate can be considered a component of the motor vehicle, as it holds the license plate to the car and protects it from damage or loss.

[0015] From one perspective, the base plate can have lateral guide elements which are arranged at an angle when mounted and are designed to be deformed laterally in the event of a frontal impact.

[0016] This describes a possible further development of the device for holding a license plate, in which the base plate has lateral guide elements. These guide elements can be arranged at an angle when mounted and deformed laterally in a frontal impact.

[0017] The lateral guide elements serve, in particular, to stabilize the device laterally and to maintain the license plate. They can be attached to the base plate, for example, in the form of flanges or angles, and mounted to the front of the vehicle during the assembly process. "Laterally" here refers specifically to the vehicle structure. A lateral arrangement is particularly relevant when, for example, the license plate holder is movable upwards or downwards. In embodiments where movement in a lateral direction is possible, the guide elements can be arranged at the top and bottom. The guide elements can be designed, in particular, as rails that engage with corresponding elements on the base plate to enable sliding movement.

[0018] When assembled, the lateral guide elements are attached to the base plate and, together with it, form a stable device, even though, as described above, movement can be imparted. If a force is transmitted to the device during a frontal collision with the vehicle, the lateral guide elements deform in such a way as to at least partially deflect the impact, thereby providing pedestrian protection. This improves personal safety and, in a closed configuration, also reduces the pedestrian's exposure to the concealed sensor. This protects both the pedestrian and the sensor from direct contact, which can also prevent damage to the sensor.This enables compliance with the leg impact requirements of pedestrian protection according to the relevant standards, as described elsewhere herein. For this purpose, the guide in the lateral area of ​​the base plate can be inclined, for example, in a cross-sectional plane through the device parallel to an x-direction. The x-direction is, in particular, the direction of the main vehicle axis, such as the direction of movement towards a frontal impact in a test scenario described elsewhere herein. This defined inclination also prevents a locking situation of an otherwise rigid guide in the x-direction. The inclination also allows the guide to fold.

[0019] The angled position of the lateral guide elements in the assembled state allows for optimal stability of the device combined with leg impact protection. The elements are arranged at an angle to enable maximum force absorption and transmission to the base plate, or to cushion and deflect impacts. This allows for the development of a degree of flexibility, as described elsewhere herein, which may be required by legal regulations.

[0020] The appropriately modified device particularly improves the functionality and stability of the device for holding a license plate and increases the safety of pedestrians and other road users.

[0021] According to one aspect, the device can have a threaded spindle arranged on the license plate holder. The device can be driven by a bevel gear with a shaft, particularly a flexible one, and a motor, so that the license plate holder is movable and no longer obscures a sensor in predetermined driving situations. This describes an optional further development of the license plate holder device, as outlined elsewhere herein. A threaded spindle and a bevel gear can be used. The device is provided with a shaft, particularly a flexible one, which can be attached to the license plate holder. This configuration makes it possible to no longer obscure the sensor in predetermined driving situations. Rather, the motor can be used to transmit movement via the shaft to expose or conceal the sensor.

[0022] The threaded spindle is an integral part of the bevel gear drive and serves primarily to connect the shaft to the license plate holder. This allows the device to hold or release the sensor in a specific position, depending on the driving situation. The threaded spindle is specifically designed to ensure a secure and permanent connection between the shaft and the license plate holder and can transmit movement of the license plate holder.

[0023] The flexible shaft is a particularly important component of the device, as it allows the sensor to be either uncovered or not obscured in certain driving situations. The movement can therefore be reversible to facilitate a transition between these two states. The shaft can be moved vertically to raise or lower the license plate, thus either covering or uncovering the sensor. In alternative embodiments, a lateral movement can also be achieved. This can be facilitated, in particular, by appropriately arranged components, as described above.

[0024] The bevel gear ensures a precise transmission of movements between the threaded spindle and the flexible shaft. It enables quick and efficient changes to the sensor's position, depending on the driving situation.

[0025] A bevel gear drive is a type of transmission consisting of a number of gears with conical teeth. Each gear set has a number of teeth that can be mounted on a shaft in a specific arrangement. The teeth on the shaft rims are arranged so that they mesh closely together and interlock tightly when the shafts rotate.

[0026] A bevel gear drive has, in particular, two or more shaft rings with tapered teeth and a number of gears with tapered teeth, which may be arranged between the shaft rings. The teeth on the gears fit, in particular, into the teeth of the outer shaft body and engage there.

[0027] A threaded spindle is, in particular, a cylindrical spindle with a circular thread profile, which may be arranged at the end of the spindle. Threaded spindles are used, in particular, to convert rotary motion into axial motion.

[0028] A flexible shaft is, in particular, a shaft with a certain aspect ratio that is capable of stretching and bending in a specific way. The flexible shaft can be used as a transmission shaft to enable linear motion. The bending can be specifically designed to occur in a direction perpendicular to a main dimension of the shaft. This allows the shaft to bend even in a frontal collision, thus enabling it to evade the impact.

[0029] The combination of a bevel gear drive, threaded spindle, and flexible shaft enables the conversion of rotary motion into axial motion. The threaded spindle is specifically mounted on one of the shaft rings of the bevel gears, while the other end of the threaded spindle is operatively connected to the license plate holder to be moved, thus transmitting the motion. The flexible shaft connects the two shaft rings and allows the rotary motion of one ring to be converted into the axial motion of a push rod. The push rod can be designed and arranged accordingly, particularly with engagement points for the shaft ring or bevel gears, to enable linear motion through engagement with the shaft ring or the bevel gear.

[0030] Overall, the combination of threaded spindle, bevel gear and flexible shaft improves the functionality and stability of the license plate holder and allows for linear movement in one direction to either cover or uncover the sensor in predetermined driving situations, ensuring optimal visibility and functionality of the sensor while also implementing pedestrian protection.

[0031] According to one aspect, the guide can be arranged and designed to fold together alongside guide flanks in the event of a frontal impact. This describes an optional further development of the license plate holder device, as outlined in the aspects described elsewhere herein. Here, the guide elements are arranged and designed to fold together in the event of a frontal impact, thereby reducing the risk of injury from the license plate and protecting a pedestrian in the event of a leg impact.

[0032] The guide elements can be attached to the base plate, for example, in the form of flanges or angles, and positioned at the front of the vehicle during the assembly process to allow the license plate holder to cover the installation space for the at least one sensor when closed. The guide elements are specifically designed to fold together in the event of a frontal impact, thus allowing the license plate to move in an x-direction. This prevents the license plate from introducing a rigidity into the structure that could, in particular, counteract the regulations described elsewhere herein.

[0033] This special configuration of the guide elements allows for a further improvement in the functionality and stability of the license plate holder and increases the safety of pedestrians and other road users.

[0034] The folding dynamics of the guide elements in a frontal impact can also allow the license plate to be held in a specific position to cover or uncover the sensor, but in a frontal impact, especially in the sensor-covering state, it can also cushion a leg impact.

[0035] This improves the protective function of the license plate holder and, in particular, ensures that a leg can be protected in the event of a leg impact in a frontal collision with the license plate and that the vehicle's sensor system is not impaired.

[0036] From one perspective, the sensor can be at least one selected from a LIDAR sensor, a RADAR sensor, a camera, in particular an RTV camera.

[0037] The device for holding a license plate may include at least one sensor, which may be of at least one of the following types: a LiDAR sensor, a radar sensor, a camera, or an RTV camera. Other sensors may also be accommodated in a mounting space, which may be located, in particular, in a vehicle chassis and / or in a bumper of a motor vehicle.

[0038] A sensor is, in particular, a device that can be used to measure and record physical quantities or changes. In this case, the sensor can be used to collect data about the vehicle's surroundings and the driving situation.

[0039] A LiDAR sensor is, in particular, a specialized laser scanner that can be used to detect the distance, speed, and direction of objects in its environment. This type of sensor is especially suitable for obstacle detection and creating a detailed 3D model of the surroundings.

[0040] A radar sensor is, in particular, a device that emits electromagnetic waves and uses them to detect the distance, speed, and direction of objects in its environment. This type of sensor is especially suitable for detecting objects in the vicinity of a vehicle and in poor visibility conditions.

[0041] A camera is, in particular, a device that absorbs light and translates it into an electronic signal to generate images. These images can be displayed on a screen or stored digitally, for example, in a storage device. This camera can be used to create a visual representation of the surroundings and / or to capture specific features of objects in the vehicle's vicinity.

[0042] An RTV camera is specifically a "Real Top View" camera that provides a top-down view of the direction of travel, for example, for parking a vehicle. A Real Top View (RTV) camera can be a special type of camera that, as part of an environmental monitoring system, enables the creation of a panoramic view of a vehicle or its surroundings. The system can include multiple cameras. These cameras are particularly capable of providing a 360-degree view of the object, especially without the need to move the camera lens.

[0043] An RTV camera system consists of multiple cameras or sensors arranged in a specific configuration. These cameras or sensors are positioned to create a combined image that provides a 360-degree top-down view of the vehicle's surroundings.

[0044] The function of an RTV camera is specifically designed to create a panoramic view of the surroundings, particularly around the vehicle, to monitor the driving situation during parking maneuvers. For this purpose, the camera can be positioned to provide a clear view of the road in one x-direction. The images or data from the cameras or sensors can then be combined to create a unified 360-degree image.

[0045] RTV cameras are particularly capable of providing a panoramic view of their surroundings without moving the camera lens. This allows for better monitoring and recognition of traffic and the vehicle's environment. RTV cameras can be used in the automotive industry to improve visibility and enhance the safety of drivers and pedestrians.

[0046] The various described options for integrating sensors into the license plate holder allow for the implementation of a suitable design to achieve optimal functionality and performance of the motor vehicle.

[0047] According to one aspect, the base plate can be connected to the motor vehicle via at least one of screws, clips, adhesive points, or joining points. "Connectable" can be understood, in particular, to mean that the device can be positioned on the motor vehicle to create a permanent connection via one of the described alternative embodiments or a combination thereof.

[0048] The optional modification of the license plate holder to the motor vehicle allows for coupling via a connection that can be at least one of the following options: screws, clips, adhesive points, or joining points. This connection is made, in particular, via an intermediate structure such as the vehicle's bumper.

[0049] A screw is, in particular, a solid, round component with a thread, used for fastening things. In this case, a screw could be used to attach the license plate holder to the bumper of the vehicle. The fastening can be done via the base plate.

[0050] A clip is, in particular, a small, solid component with a specific shape that can be used to hold or firmly connect two components together. A clip can be used to attach a license plate holder to the bumper or chassis of a motor vehicle. This attachment can be made via the base plate.

[0051] An adhesive joint is, in particular, a special shape that can be used to hold two components together with an adhesive. An adhesive joint can be used to attach a license plate holder to the bumper or chassis of a vehicle. This attachment can be made via the base plate.

[0052] A joining point is, in particular, a structure designed to join two components via interlocking shapes. A joining point can be used to attach a license plate holder to the bumper or chassis of a motor vehicle. This attachment can be achieved via the base plate.

[0053] Overall, the various options allow the license plate holder to be connected to the vehicle in a secure and stable manner. In particular, an intermediate structure such as a bumper is used to establish a solid connection between the device and the vehicle. This allows the sensor's installation space to be framed by a base plate. In some embodiments, the base plate may have a recess through which a sensor can see when the license plate holder is in a position where it does not obstruct the sensor's installation space from a given viewing direction.

[0054] In one respect, the device can meet the pedestrian protection requirements for leg impact according to UNR127, as they were in force on the filing or priority date, particularly in the USA, the EU, or Germany. The license plate holder and a motor vehicle in which it is integrated can meet the pedestrian protection requirements as laid down in a relevant regulation or standard. Appropriate tests can also be carried out, for example, using a leg impactor as described elsewhere herein.

[0055] Pedestrian protection refers specifically to measures and regulations designed to improve the safety of pedestrians in road traffic. This can also include requirements for vehicle design and the inclusion of safety features to minimize the risk of injury to pedestrians in accidents.

[0056] A pedestrian is specifically a person who moves through traffic on foot or using bicycles or other non-motorized means of transport – e-scooters, for example. The protection of pedestrians is an aspect of traffic law and road safety that can be implemented using this device.

[0057] A leg impact refers specifically to a type of accident in which a pedestrian is struck by a vehicle and their leg collides with the vehicle. The impact of such a collision on the vehicle structure can result in injury to the pedestrian.

[0058] UNR127 is an international standard that defines requirements for pedestrian protection in road traffic. This standard contains regulations and requirements for the use of safety features in vehicles to minimize the risk of injury to pedestrians. Furthermore, the standard specifies appropriate test setups, such as how a leg impact test can be implemented.

[0059] The device for holding a license plate and the motor vehicle in which it is integrated comply in particular with the requirements of pedestrian protection in order to enable the protection of pedestrians in road traffic.

[0060] From an independent perspective, a motor vehicle may have a device for holding a license plate, as described elsewhere herein.

[0061] The motor vehicle can be described by the features, properties, and advantages of the device for holding a license plate. This also applies across the category boundaries of method, device, and system. Thus, the device for holding a license plate can also be described by the features, properties, and advantages of the motor vehicle. For the sake of readability and conciseness, a repetition of all these features, properties, and advantages is omitted.

[0062] Further advantages, features, and details of the invention will become apparent from the following description, in which exemplary embodiments of the invention are described in detail with reference to the drawings. The features mentioned in the claims and in the description can be essential to the invention individually or in any combination. The drawings schematically show: Fig. 1A a schematic representation of an exemplary embodiment of a motor vehicle with an open installation space for the sensor; Fig. 1B a schematic representation of an exemplary embodiment of a motor vehicle with an enclosed installation space for the sensor; Fig. 2 a schematic representation of an exemplary embodiment of a device for holding a license plate; Fig. 3A a schematic sectional view of an exemplary embodiment of a device for holding a license plate; Fig. 3B a schematic sectional view of an exemplary embodiment of a device for holding a license plate with a leg impactor that strikes next to the guide elements in a frontal impact; Fig. 3C a schematic sectional view of an exemplary embodiment of a device for holding a license plate with a leg impactor that strikes the guide elements in a frontal impact; Fig. 4 a schematic sectional view of an exemplary embodiment of a device for holding a license plate in an open state; and Fig. 5 a schematic sectional view of an exemplary embodiment of a device for holding a license plate in a closed state.

[0063] Fig. Figure 1A shows a schematic representation of an exemplary embodiment of a motor vehicle 1 with an open installation space for a sensor 4, which is located in Fig. 1B is located behind a license plate in an enclosed installation space. This implements a concept for fulfilling pedestrian protection leg impact according to UNR127 for motor vehicles 1 with a height-adjustable license plate holder 51 in order to cover a sensor 4 which may be located in a front area 10 of the motor vehicle in an installation space.

[0064] Motor vehicles must meet the legal requirements for pedestrian protection in order to be approved. This includes, in particular, the load case of head impact on the hood, but also leg impact on the front of the vehicle. The latter load case simulates the impact of a pedestrian with the front of the vehicle in an accident at 40 km / h. This is achieved using a leg impactor, as described in the [relevant regulations / guidelines]. Fig. 3B, Fig. The vehicle structure is checked using the schematic representation in Figure 3C. The leg impactor 100, also known as the Flexible Pedestrian Legform Impactor, is used for corresponding crash tests. It replicates the structure of the human leg as a substitute test body. An example of a Leg Impactor 100 is a FlexPLI.

[0065] The legal requirement specifically includes compliance with biomechanical limits. For example, the FlexPLI system assesses knee ligament strain, cruciate ligament strain, and bending moments in the lower leg during leg impact testing. Due to these legal requirements, the vehicle structure would need to be designed with a correspondingly softer profile.

[0066] In the course of the further development of motor vehicles towards autonomous driving, a large number of sensors 4 are being integrated, especially in the front of the vehicle 10. These sensors, e.g. radars, cameras, optical sensors, etc., are arranged in a defined installation space and can be exposed by the device 5 via a translational guide 61, particularly upwards, as shown in Fig. Figure 1A shows the schematic representation of when they are to be used. This allows the viewing area 41 of the sensor 4 to be exposed. When not in use, the device 5 can cover the installation space by means of a downward translational movement 61, in order to conceal the sensor 4. This allows the viewing area 41 of the sensor 4 to be obscured.

[0067] The license plate holder 5 may be subject to legal regulations specifying a defined size and position. Depending on the position of the sensor and the field of vision, the license plate holder 51 is located within the field of vision 41. This means, in particular, that the sensors 4 can be positioned very prominently and far forward in the vehicle.

[0068] The illustrated device 5 shows a license plate holder 51 which can move translationally 61 in its position. When the vehicle 1 is at rest or during maneuvering, the sensor 4 can be concealed behind the license plate holder 51 and not visible. When the sensor 4 is needed, the license plate holder 51 moves in a specific manner, clearing the necessary area so that the sensor 4 can function and nothing obstructs the field of vision 41.

[0069] Fig. Figure 2 shows a schematic representation of an exemplary embodiment of a device 5 for holding a license plate 53. The license plate holder 5 can be designed in two parts. A base plate 52 can be mounted on the front of the vehicle 10. This base plate 52 serves in particular as a guide 7 for the actual license plate holder 51. The license plate holder 51 can move translationally upwards on guide elements 71, which can be projected over by a portion of the license plate holder 51. This creates a translationally movable guide 7, in which the guide elements 71 can be designed as rails that transmit movement by projecting over a side portion of the base plate 52, which can have the corresponding guide elements 71. Other embodiments are also possible, in which, for example, the guide elements 71 can be associated with the license plate holder 51.

[0070] Fig. Figure 3A shows a schematic sectional view of an exemplary embodiment of the device 5 for holding the identification mark 53. Fig. Figure 3A shows a cross-sectional view from above, where the section plane can be parallel to a ground plane in an x-direction. The vehicle front 10 receives the base plate, for example, via screws or clips 6. The illustrated embodiment allows the leg impact requirement of the pedestrian protection system to be met. For this purpose, the guide 7 can be inclined in the lateral area of ​​the base plate 52 and can extend beyond it. This defined inclination 70 prevents, in particular, a blocking situation of the rigid guide 7 in the x-direction. The inclination 70 can allow the guide 7 or the guide elements 71 to fold. For this purpose, the guide elements 71 can form a Z or S shape – or correspondingly in a mirror image. This allows a spring-like compression to be formed.It may be provided that the areas furthest from the front of the vehicle have a greater span than the areas closer to the front. This assignment is to be understood in particular as meaning that the device is arranged in front of a vehicle front 10 or in front of a plane that can be spanned by it. This plane is in particular perpendicular to the cutting plane as shown in the figure. Fig. 3A is shown.

[0071] Fig. Figure 3B shows a schematic sectional view of an exemplary embodiment of the device 5 for holding the license plate 53 with a leg impactor 100 which, in a frontal impact, strikes next to the guide elements 71. The section plane corresponds in particular to the section plane as it is defined with respect to the Fig. 3A is shown. Fig. Figure 3A shows the leg impact in a top view. The leg test body 100 or leg impactor 100 impacts the motor vehicle 1, particularly in the X direction, bending and deforming the license plate holder 51. The guide 7 can bend outwards next to the guide 7 81 upon impact. The impact next to the guide 7 therefore occurs particularly in an area where no guide elements 71 are arranged.

[0072] Fig. Figure 3C shows a schematic sectional view of an exemplary embodiment of the device 5 for holding the license plate 53 with the leg impactor 100 which impacts the guide elements 71 in a frontal impact. Fig. Figure 3C shows the impact of the leg test specimen 100 directly onto the area of ​​the guide 7, specifically in a region of the guide elements 71. The inclined position 70 of the guide elements 71 leads in particular to guide flanks 72, which can cause the guide 7 to fold 50, similar to a spring. Clips 6 can be provided as locking pins.

[0073] Fig. Figure 4 shows a schematic sectional view of an exemplary embodiment of the device 5 for holding the identification mark 53 in an open state. Fig. 4 shows a section perpendicular to the cutting planes in the Fig. 3A to 3C and perpendicular to the plane of the vehicle front 10, the device 5 is shown in a so-called side view. In particular, the adjustment drive of the license plate holder 51 is shown to describe its function. The state of the Fig. 4 corresponds in particular to the state as it exists in an installation situation in the Fig. Figure 1A shows the open resting state in which the field of view 41 of the sensor 4 is exposed, thus enabling the sensor 4 to function. The vehicle front 10 and the base plate 52 mounted on it, as well as the license plate holder 51, can be arranged relative to each other in such a way as to expose a space for the sensor 4, to make the sensor 4 visible from the outside, or to make the surroundings visible to the sensor.

[0074] The license plate holder 51 has, in particular at the top, a receptacle 24 for a threaded spindle 23. The threaded spindle 23 is driven via a bevel gear 22. The bevel gear 22 can, for example, be driven by a motor 20 via a flexible shaft 21 extending from the concealed vehicle structure. Various guides 28 in the base plate 52 guide the threaded spindle 23. By rotating the flexible shaft 21 62, the bevel gear 22 is driven, thus rotating the threaded spindle 23. This rotation raises the license plate holder 51.

[0075] Fig. Figure 5 shows a schematic sectional view of an exemplary embodiment of the device 5 for holding a sign 53 in a closed state. Fig. 5 shows a section perpendicular to the cutting planes in the Fig. 3A to 3C and perpendicular to the plane of the vehicle front 10, the device 5 in a so-called side view. The section plane corresponds in particular to the section plane of the Fig. 4. In particular, the adjustment drive of the license plate holder 51 is shown in order to describe its function. The state of the Fig. 5 corresponds in particular to the state as it exists in an installation situation in the Fig. Figure 1B shows the closed resting state in which the field of view 41 of the sensor 4 is obscured. The vehicle front 10 and the base plate 52 mounted on it, as well as the license plate holder 51, can be arranged relative to each other in such a way as to obscure a mounting space of the sensor 4, so that the sensor 4 is not visible from the outside.
