Description

Technical Field

[0001] The present invention relates to a holding device for a vehicle sensing mechanism, comprising a frame that can be fixed to a structural element of the vehicle and a sensor halter configured to hold the sensor.

[0002] Furthermore, the present invention also relates to a motor vehicle having a holding device for a motor vehicle sensing mechanism. Background Technology

[0003] In modern motor vehicles, sensors for various driver assistance systems are mostly housed in the ventilation grille below the vehicle's crossbeams. Legislators require that these sensors remain undamaged by minor impacts (such as those that might occur in a low-speed rear-end collision), thus reliably ruling out driver assistance system failures. Furthermore, functional loss due to sensor displacement should be avoided.

[0004] Therefore, to protect the sensors, they are mostly fixed to the vehicle's crossbeams. The vehicle must then have sufficiently large overhangs to prevent damage to the sensors in the vehicle's sensing mechanism from deformation caused by a frontal impact. Furthermore, it is known in the prior art to mount the vehicle sensing mechanism in the shadow of the crossbeams for protection; however, due to the conical radiation of some sensors, a significantly larger free cross section is required in the ventilation grille to provide the sensors with a clear view.

[0005] A vehicle equipped with a radar assembly is known from US 9,956,993 B1. The radar assembly has a radar carriage movably connected to a radar mount. A preload mechanism pushes the radar carriage toward a position of use away from the radar mount. By applying a force, the radar carriage can be temporarily moved relative to the preload mechanism in the direction of the radar mount.

[0006] A holding device for a camera in the rear area of ​​a vehicle is known from DE 10 2019 125 674 A1, wherein the camera, which can be placed in a segment in the rear area, can be swung from its functional position to a protected position by means of a swingable holding device that carries the camera.

[0007] US 2019 / 0308565 A1 discloses a sensor device for a vehicle. The sensor device includes a clamp (klammer) oscillating about a first axis between a first position and a second position, and a sensor disposed at the clamp.

[0008] A movable sensor for autonomous driving functions is known from US 2020 / 0331496 A1.

[0009] US 9,834,164 B1 discloses an impact sensor for an active motor cover system. Summary of the Invention

[0010] The objective of this invention is to provide a retaining device for a motor vehicle sensing mechanism, by means of which damage or displacement of the sensors of the motor vehicle sensing mechanism is avoided in the event of an accident at a low speed, and the retaining device enables shorter vehicle overhangs.

[0011] To address the objective of this invention, a holding device for a vehicle sensing mechanism is proposed. This holding device includes a frame that can be fixed to a structural element of the vehicle and a sensor holder configured to hold a sensor. Furthermore, a first swing bracket is pivotally supported on a first side of the frame, and a second swing bracket is pivotally supported on a second side of the frame opposite to the first side. The sensor holder is supported on the first and second swing brackets, and a pre-tightening mechanism is provided. This pre-tightening mechanism is configured to pre-tighten the first and second swing brackets to a working position. The pre-tightening can be overcome by applying a predetermined force to the sensor holder, allowing the sensor holder to sink into the frame along the direction of movement.

[0012] Motor vehicle sensing mechanisms may include sensors for driver assistance systems or other functions of the motor vehicle. The sensors may be arranged or are already arranged at the sensor mount of the retaining device.

[0013] When used as specified, the retaining device is fixed to a structural element of the vehicle. This structural element may be a crossbeam or a lower load-bearing plane of the vehicle. The retaining device may be fixed to both the crossbeam and the lower load-bearing plane, but it is also conceivable that the retaining device may be fixed only to the crossbeam or only to the lower load-bearing plane.

[0014] The frame of the retaining device according to the invention is preferably constructed in an approximately rectangular shape and is oriented approximately vertically when arranged in a motor vehicle.

[0015] A first swing bracket and a second swing bracket are provided with swingable support on a first side of the frame and a second side of the frame opposite to the first side (the first and second sides can correspond to the right and left sides when arranged in a motor vehicle). Preferably, the swing axes of the first and second swing brackets extend parallel to each other. More preferably, the two swing axes of the first and second swing brackets extend approximately vertically when arranged in a vehicle.

[0016] The swing bracket can preferably pivot relative to the frame individually or together.

[0017] The sensor mount is supported at the first swing bracket and the second swing bracket.

[0018] The frame can define a frame plane. In the position of use, the sensor holder is then pressed out from the frame plane defined by the frame by means of a pre-tightening mechanism, that is, the sensor holder plane defined by the sensor holder is parallel to and spaced apart from the frame plane.

[0019] When a predetermined force is applied (which may occur, for example, in the event of a low-speed impact or accident, such as a so-called "parking collision"), the preload applied to the first and second swing brackets by the preload mechanism can be overcome. The first and second swing brackets swing in, and the sensor holder supported at the first and second swing brackets sinks or sinks out along the direction of movement toward the frame, preferably sinking or sinking into the frame plane. This sinking or sinking of the sensor holder protects the sensor held at the sensor holder from damage. Furthermore, it prevents the sensor from shifting, especially with respect to its orientation. This allows for greater freedom in the design of the vehicle, and in particular, allows for shorter vehicle overhangs, as a larger vehicle overhang is no longer needed for protecting the sensor and absorbing impact deformation.

[0020] Preferably, after the predetermined force is removed, the pre-tightening mechanism pre-tightens the first swing bracket and the second swing bracket back to the use position, so that the sensor frame moves back in the opposite direction of movement, preferably from the frame plane of the frame.

[0021] The direction of movement is preferably perpendicular to the plane of the frame supported by the frame.

[0022] It is further advantageous to configure the pretensioning mechanism to include at least one, preferably two, spring elements associated with the first swing bracket and at least one, preferably two, spring elements associated with the second swing bracket.

[0023] The spring element is preferably arranged between the frame and the first and second swing brackets such that the spring element preloads the swing brackets from the plane of the frame to the working position.

[0024] It is further advantageous to configure at least one spring element associated with the first swing bracket and at least one spring element associated with the second swing bracket as torsion springs.

[0025] To transmit the preload applied by the spring elements, especially the torsion springs, supports can be installed at the swing bracket and the frame.

[0026] Preferably, the first swing bracket and / or the second swing bracket have a support element for swingably supporting itself at the frame, and at least one cantilever protruding from the support element (more preferably at approximately a right angle), and at least one guide element fixed to one end of the cantilever opposite to the support element.

[0027] The first and / or second swing brackets are pivotally or rotatably supported at the frame via support elements. In the usage position, at least one cantilever preferably protrudes from the frame plane of the frame. Therefore, a guide element fixed to the end of the cantilever opposite to the support element is also arranged outside the frame plane. The guide element is also the connection between the first and / or second swing brackets and the sensor holder. Since the guide element is arranged outside the frame plane, the sensor holder is also arranged outside the frame plane.

[0028] Preferably, the first swing bracket and the second swing bracket can be configured to be identical or mirror-symmetrical.

[0029] Further advantageously, the support element can be a hollow tube that rotatably surrounds a rod disposed on a first side and / or a second side of the frame, and / or the guide element is a guide rod that extends parallel to the support element, and / or at least two cantilevers are provided, wherein the two cantilevers are disposed at the ends of the support element.

[0030] Preferably, the frame, which is approximately at right angles, has rods on the first and second sides, respectively. Correspondingly, hollow tube support elements rotatably surround the respective rods, allowing the first and second swing supports to rotate about their respective associated rods of the frame. Guide elements, configured as guide rods and located at the ends of the cantilever, extend approximately parallel to the hollow tube. Two cantilever arms can be provided, each located at an end of a corresponding support element. In this design, the first and / or second swing supports are thus constructed approximately like rectangular guide rods.

[0031] Advantageously, the sensor holder can be configured to have at least one guide receiving portion, particularly an elongated hole, for accommodating a guide element, wherein the guide element can slide in the guide receiving portion as the sensor holder sinks toward the frame.

[0032] For example, if a force is applied to the sensor holder due to a low-velocity impact, this force is transmitted to the frame and preload mechanism via the guide element (on which the sensor holder is fixed), the cantilever, and the support element. If the force exceeds a predetermined force, the swing bracket can be swung in from its position along the plane of the frame. Here, due to the pivoting of the first and second swing brackets, the distance between the guide elements of the first and second swing brackets decreases. From the perspective of the sensor holder, the guide elements of the first and second swing brackets move toward each other. To achieve this toward-each-other movement, the sensor holder preferably has a guide receiving portion for each guide element, which is preferably constructed as an elongated hole. The guide receiving portion, especially the elongated hole, is preferably oriented approximately parallel to the plane of the frame.

[0033] Preferably, a guide bracket can be provided that is pivotally supported on the frame, wherein the pivot axis of the guide bracket is oriented perpendicularly to the pivot axis of the pivot bracket, and the sensor frame is supported on the guide bracket in such a way as to prevent the sensor frame from moving perpendicular to the direction of movement.

[0034] When the swing bracket is positioned into the frame plane, in order for the sensor holder to sink into the frame direction along the direction of movement, the guide elements of the first and second swing brackets move towards each other within the guide brackets, and more preferably within the elongated holes. Therefore, between the used position and the fully inserted position of the swing brackets, the sensor holder can move in a direction transverse to the direction of movement. To suppress this lateral movement, a guide bracket that is swingably supported at the frame can be provided. Preferably, the guide bracket, which can also swing in the direction of the frame plane, can be swingably fixed not only at the frame but also at the sensor holder. Because the guide bracket can only swing about a swing axis preferably perpendicular to the swing axes of the first and second swing brackets, lateral displacement of the sensor holder can be suppressed by the corresponding rotatable support of the sensor holder at the swing bracket.

[0035] Preferably, the guide bracket has a first rod rotatably arranged on the frame, a guide disk arranged on the end side of the first rod, and a second rod arranged parallel to the first rod and supported on the sensor frame, wherein the second rod is slidably arranged in a groove or elongated hole in the guide disk.

[0036] The guide bracket not only prevents the sensor holder from moving laterally in the direction of motion, but also prevents it from tipping over relative to the frame. In other words, the guide bracket ensures that the sensor holder does not twist or tip over about an axis extending parallel to the plane of the frame as it sinks into the frame along the direction of motion.

[0037] However, in principle, it can also be advantageous to allow the sensor mount to tilt. This is especially advantageous if the force is applied to the sensor mount off-center rather than centrally. This is, for example, the case in impact events with large offsets.

[0038] In order to allow tilting around the vertical axis of the sensor frame, instead of a guide bracket, or in the case of a guide bracket designed accordingly, the frame can be configured to have elastic locking devices at the first and second sides, wherein the locking device is preferably a spring plate, and more preferably, the locking device (especially preferably at the end side) has an inclined plane or a chamfer.

[0039] Preferably, the sensor frame can be configured such that the locking device support, in particular a material protrusion, forms a support for the locking device, and / or the frame has locking device receiving portions, in particular grooves, on a first side and a second side, wherein the resilient locking device is arranged in the locking device receiving portion.

[0040] Preferably, two locking devices are provided on the first side and the second side of the frame, and the sensor rack has two locking device supports on the first side and the second side, respectively.

[0041] By incorporating locking devices, particularly spring plates, an additional locking mechanism is provided in the direction of the predetermined force, which must first be overcome before the spring elements of the swing bracket can be loaded. This is particularly advantageous if the spring stiffness of the spring elements of the first and second swing brackets may decrease over their service life, and therefore a permanently constant force level cannot be guaranteed. A second advantage of the locking devices, preferably constructed as spring plates, is that these locking devices simultaneously ensure lateral guidance transverse to the direction of movement, preventing the sensor holder from sliding to the left or right.

[0042] Furthermore, the locking device enables the sensor holder to sink towards the frame only on the first side or only on the second side during an impact event, and thus can tilt about a preferably vertical axis. This achieves the goal that, in the event of an impact event with a large sinking amount, the locking caused by the locking device is overcome only on one side of the frame.

[0043] After the predetermined force is removed, the first and second swing brackets swing back to their operating positions by means of spring elements, thereby causing the sensor holder to return to its original operating position. The locking device, preferably the spring plate, then locks again, thereby ensuring that the sensor holder is stably oriented in the operating position on the frame.

[0044] The inclined plane allows the locking device, especially the spring plate, to be pushed open without obstruction between the locking device and the sensor holder, particularly the locking device support constructed as a material protrusion. The inclined plane can be achieved here by the bent end region of the spring plate. Alternatively, the locking device support, especially the material protrusion, can have chamfered sections.

[0045] Another solution to the objective of this invention is to provide a motor vehicle having the aforementioned retaining device.

[0046] Preferably, the retaining device can be fixed at the crossbeam and / or the lower load plane of the motor vehicle. Attached Figure Description

[0062] exist Figures 1 to 7 The image shows a first holding device 100 for a motor vehicle sensing mechanism according to the present invention. Figure 1 The holding device 100 is shown in an exploded view. Figures 2 to 4 The image presents the retaining device 100 from different perspectives in the absence of external force. Figures 5 to 7 A retaining device 100 is shown in the case of force action, for example, caused by a rear-end collision at a low speed.

[0063] The retaining device 100 includes a frame 10, according to Figures 2 to 7 The frame can be fixed to structural element 11 of the motor vehicle 200, which is only partially presented. Structural element 11 consists of a crossbeam 12 and a lower load-bearing plane 13.

[0064] The frame 10 is generally rectangular in shape. The holding device 100 includes a sensor holder 14 at which unexposed sensors of the vehicle sensing mechanism can be arranged or held. A first swing bracket 16 is pivotally supported at a first side 15 of the frame 10. A second swing bracket 18 is pivotally supported at a second side 17 of the frame 10. Furthermore, a preload mechanism 19 is provided, having a total of four spring elements 21 configured as torsion springs 20. The spring elements 21 preload the first and second swing brackets 16 and 18 via supports 22 at the frame 10 and the swing brackets 16 and 18 to preload them into their operating position. Each of the swing brackets 16 and 18 has a support element 24 configured as a hollow tube 23, which rotatably surrounds a rod 25 of the frame 10. Cantilever arms 26 are respectively provided at the ends of the hollow tubes 23. Guide elements 28 configured as guide rods 27 are respectively provided between the ends of the cantilever arms 26 opposite to the support elements 24. The guide rod 27 is slidably arranged in the guide receiving portion 29 of the sensor holder 14. Furthermore, a guide bracket 30 is provided, which is pivotally connected to the frame 10. This guide bracket has a first rod 31 rotatably arranged on the frame 10, a guide disk 32, and a second rod 33 arranged parallel to the first rod 31. The second rod 33 is supported on the sensor holder 14 via a corresponding bracket 34. The second rod 33 is also slidably arranged in an elongated hole 35 in the guide disk 32. Figure 1 ).

[0065] If it hits object 36 ( Figure 4 and Figure 7For example, when colliding with another motor vehicle, if a force exceeding the predetermined force is applied to the sensor mount 14, then the sensor mount 14 will... Figures 2 to 4 The position shown is used in overcoming the preload applied to the swing rods 16, 18 by the preload device 19. Figure 4 and Figure 7 The sensor mount 14 moves in the direction of motion 37 marked in the diagram toward the frame 10, thereby causing the sensor mount 14 to move as shown in the diagram. Figures 5 to 7 It sinks towards frame 10 as shown. Here, as particularly... Figure 3 and Figure 4 As can be seen in the comparison, the swing brackets 16 and 18 are swung into the frame plane of the frame 10. Therefore, the guide rods 27 of the swing brackets 16 and 18 move towards each other. To avoid obstruction, the guide rods 27 are slidably arranged in the guide receiving portion 29 of the sensor holder 14. To simultaneously prevent lateral displacement of the sensor holder 14 in the direction of movement 37, the sensor holder is fixed in the direction transverse to the direction of movement 37 by means of the guide bracket 30. Here, obstruction caused by the guide bracket 30 is avoided by the sliding arrangement of the second rod 33 of the guide bracket 30 in the elongated hole 35 of the guide plate 32. After the force is released, the sensor holder 14 is pushed back by the spring element 21 of the preload mechanism 19. Figures 2 to 4 The usage location is shown in the figure.

[0066] exist Figures 8 to 14 The image shows a second holding device 100 for a motor vehicle sensing mechanism according to the present invention. Figure 8 The holding device 100 is shown in an exploded view. Figure 9 and Figure 10 The image shows a retaining device 100 in the absence of external force. Figures 11 to 14 A retaining device 100 is shown in the case of force action, for example, caused by a rear-end collision at a low speed.

[0067] according to Figures 8 to 14 The retaining device 100 has the same or corresponding components marked with the same Figures 1 to 7 The same reference numerals are used in the accompanying drawings.

[0068] Relative to according to Figures 1 to 7 The holding device 100, according to Figures 8 to 14The frame 10 of the retaining device 100 does not have a guide bracket 30. Instead, a first locking device receiving portion 39 configured as a groove 38 is provided in the frame 10. A locking device 42, configured as a spring plate 43, is arranged in the groove 38. On the side, the sensor holder 14 has a locking device support 40, which is constructed of material protrusions 41. The spring plate 43 abuts against or locks against these material protrusions. Therefore, the spring plate 43 causes additional preload, which must be overcome by force before the spring element 21 of the preload mechanism 19, configured as a torsion spring 20, is loaded. In addition, the spring plate 43 ensures the lateral guidance of the sensor holder 14.

[0069] Figure 10 and Figure 12 Detailed views of the locking device receiving portion 39, the locking device 42 configured as a spring plate 43, and the locking device support 40 are shown. The spring plate 43 prevents the locking device support 40, configured as a material protrusion 41, from sinking into the groove 38 of the sensor holder 14. If a sufficiently large force is applied to the sensor holder 14, the material protrusion 41 will... Figure 12 As shown, the spring plate 43 is pushed outward, and the material protrusion 41 can penetrate into the groove 38, and the swing bracket 18 can be swung into the plane of the frame 10 from the use position. To avoid obstruction between the material protrusion 41 and the locking device 42 configured as the spring plate 43, the spring plate 43 has an inclined plane 44 in the form of a bent end region 45.

[0070] exist Figure 13 and Figure 14 The function of the locking device 42 and the locking device support 40 is illustrated. Under the action of an eccentric force, the sensor frame 14 can sink into the frame 10 on one side along the direction of movement 37, wherein the sensor frame 14 simultaneously tilts or pivots about a vertical axis, which extends approximately parallel to the swing axis of the swing supports 16, 18. Under the action of a central force, the sensor frame 14 can also... Figure 11 As shown, it sinks into the direction of motion 37 toward the frame 10 without tipping over. After the force is removed, the sensor holder 14 returns to its original position and locks itself back into the locking device 42.
