Description

Technical Field

[0001] The invention relates to a base, a mirror foot and a mounting assembly for mounting an interior rearview mirror of a vehicle. Background Art

[0002] In vehicle construction, interior rearview mirrors are usually mounted on the windshield in the vehicle interior. A known mounting assembly comprises a base that is mounted on the windshield. Mirror legs are mounted on the base and are screwed onto the base during mounting. In the final mounted position, the base and the mirror legs bear against each other and are held together by means of a torsion spring. Finally, the interior rearview mirror is arranged on the mirror legs.

[0003] For example, it is known from DE 21 2018 000 374 U1 that four positioning grooves of a holding device are embedded in four positioning mechanisms on a windshield button, and the holding device and the windshield button are held together by means of a fixing clip. The windshield button is also provided here for accommodating a sensor.

[0004] In addition, DE11 2019 000 611 T5 discloses that the five mating protrusions of the five protrusions of the bearing seat and the mating grooves in the supporting surface of the mounting base are abutted against each other and pressed against each other by the preload force of the arm of the bearing seat mounting leaf spring. Five abutting supporting sections are thus formed. The sensor assembly is also arranged between the bearing seat and the mounting base.

[0005] But the shortcoming of known mounting assembly is that they have complicated structure and therefore need big space requirement.In addition, in vehicle driving operation, undesirable vibration can occur in the mounting assembly, and known mounting assembly can not prevent this vibration. Summary of the invention

[0006] The object of the present invention is therefore to provide a low-vibration, space-saving mount for mounting an interior rearview mirror of a vehicle and a corresponding mirror foot as well as a corresponding mounting assembly.

[0007] The solution according to the invention to this object is achieved by the features of claims 1, 8 and 9. Advantageous developments of the invention are revealed in the dependent claims.

[0008] The present invention relates to a base for being arranged on a windshield of a vehicle and for accommodating a mirror foot of an interior rearview mirror, the base having a base plane. According to the present invention, at least six resistance surfaces are arranged on the base plane; every two resistance surfaces are at least partially arranged in a common resistance plane, thereby forming at least three resistance planes; each of the resistance planes is oriented relative to the base plane so that the resistance plane intersects with the base plane in a straight line, thereby forming at least three straight lines in the base plane, the straight lines have intersection points with acute angles at least in pairs with each other, thereby forming at least three acute intersection angles, the intersection points are arranged between the resistance surfaces belonging to the intersecting straight lines, and the acute intersection angles are equal.

[0009] Due to the equal acute angles, the base can transfer the forces occurring during vehicle operation in a uniformly distributed manner, thereby minimizing vibrations. The base can thus absorb or transfer these forces symmetrically. In addition, the resistance surface can absorb or transfer the occurring forces particularly well due to its planar design and can be designed to save space compared to interlocking elements. In this context, the term "equal acute angles" is generally understood to mean that the acute angles are substantially equal and differ only within a tolerance range of ±3°.

[0010] Preferably, six resistance surfaces are provided on the base plane and the acute angles are 60° in each case. Forces can be absorbed particularly well when the six resistance surfaces and the acute angles are 60° in each case. Here, the resistance surface corresponds to half a fulcrum of a static system, which in turn is statically and completely defined by three complete fulcrums. Thus, overdefinition is avoided with six resistance surfaces, which further saves space. Generally speaking, in the mechanical sense, a resistance surface can be understood as half a fulcrum. A stable orientation in space can be defined by three fulcrums.

[0011] In a preferred embodiment, the two resistance surfaces are at least partially arranged in a common resistance plane so that when the base is installed in the vehicle, the resistance surfaces are arranged to absorb the impact forces caused by a collision in the vehicle's X direction. The impact forces can be caused, for example, by the head of a vehicle occupant accelerating forward. As a result, the impact forces in the vehicle's X direction can be absorbed particularly well by the base up to a certain threshold value. The two resistance surfaces are arranged in this case so that the temples separate from the base when the impact forces exceed the threshold value, thereby preventing head injuries. The impact forces are generally defined in the FMVSS 571.111 regulation.

[0012] In order to limit the temples from falling off the base, the temples are preferably connected to the base via a limiting strap. In one embodiment, the base therefore has a side wall in which a through hole for accommodating a clip for the limiting strap is provided. The clip is connected to the limiting strap and is embedded in the through hole.

[0013] In one embodiment, an engagement region for engaging with a planar torsion spring is formed on the side wall. Thus, the mirror foot can be fixed on the base in an advantageous manner by means of the torsion spring.

[0014] Particularly preferably, the engagement region comprises a fixing element protruding from the side wall for engagement with the torsion spring and at least two recesses, wherein a pre-fixing rib for engagement with the torsion spring is provided on the side wall for each recess. Before the temple leg is rotated into its final installation position, the temple leg can be pre-fixed on the pre-fixing rib by means of the torsion spring during installation. This provides a simplified installation with greater safety, since the temple leg can be pre-fixed on the base in the first hand position and can be comfortably rotated into the final installation position in the second hand position, wherein the second hand position is more suitable for rotation. As a result, the temple leg is prevented from falling off when switching from the first hand position to the second hand position.

[0015] In all embodiments, the angle between the base plane and the respective resistance plane is preferably less than 90° and preferably in the range of 25° to 45°, particularly preferably in the range of 30° to 45°. Thus, with regard to the impact force in the vehicle X, Y or Z direction, the threshold for the temple to fall off the base can be set particularly advantageously.

[0016] The present invention also relates to a mirror foot for connection with a base and for setting an interior rearview mirror on a windshield of a motor vehicle, the mirror foot having a mirror foot plane. According to the present invention, at least six fixing surfaces are arranged on the mirror foot plane; two fixing surfaces are at least partially arranged in a common fixing plane, thereby forming at least three fixing planes; each of the fixing planes is oriented relative to the mirror foot plane so that the fixing plane intersects with the mirror foot plane in a straight line, thereby forming at least three straight lines in the mirror foot plane, the straight lines have intersection points with each other at least in pairs, with acute angles, thereby forming at least three acute intersection angles, the intersection points are arranged between the fixing surfaces belonging to the intersecting straight lines, and the acute intersection angles are equal.

[0017] Due to the equal acute angles, the temples can transfer the forces occurring during vehicle operation in a uniformly distributed manner, thereby minimizing vibrations. The temples can therefore absorb or transfer these forces symmetrically. In addition, the fastening surface can absorb or transfer the occurring forces particularly well due to its planar design and can be designed to save space compared to interlocking elements. In this context, the term "equal acute angles" is generally understood to mean that the acute angles are substantially equal and differ only within a tolerance range of ±3°.

[0018] The present invention also relates to a mounting assembly for mounting an interior rearview mirror of a vehicle, the mounting assembly comprising a base according to one of the aforementioned embodiments and a mirror leg according to the aforementioned embodiment, wherein in the final mounted state, the base and the mirror leg are connected to each other in such a way that a resistance surface and a fixing surface respectively abut against each other.

[0019] Since the acute angles of intersection are equal both in the base and in the temple, the mounting assembly can transfer the forces occurring during vehicle operation in a uniformly distributed manner, thereby minimizing vibrations. Thus, the pairs of resistance surfaces and fastening surfaces that abut against one another in a plane can absorb or transfer these forces symmetrically. In addition, the resistance surfaces and fastening surfaces can absorb or transfer the occurring forces particularly well due to their planar design and can be designed to save space compared to interlocking elements.

[0020] According to a preferred embodiment, the mounting assembly comprises a sensor for being arranged on a windshield of a vehicle, wherein in the final mounted state, the sensor and the base connected to the temple are arranged at different positions on the windshield, preferably side by side. Since the base according to the invention is designed to save space as described above, the base is advantageously arranged on the windshield next to the sensor, thereby providing a flatter design of the base and the sensor in the interior. Therefore, according to the invention, the sensor is not arranged in the base.

[0021] Preferably, the mounting assembly may also include a windshield of the vehicle.

[0022] Furthermore, a vehicle is provided which has a base according to one of the preceding embodiments, a temple according to the preceding embodiments or a mounting arrangement according to one of the preceding embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 1 A schematic perspective view of an embodiment of a base 10 according to the invention is shown, which is intended to be arranged on a windshield of a vehicle and to accommodate a Figure 2 The mirror foot 20 for the interior rearview mirror in the vehicle. The base 10 is preferably configured in a circular shape.

[0030] In this case, the base 10 preferably extends at least partially in the base plane 12. Figure 1 As shown in , the base plane 12 can be formed by the surface of the base. However, it is also conceivable that the base plane 12 is only defined by an abstract plane. Preferably, each part of the base 10 extends into the plane or at least intersects the plane.

[0031] Six resistance surfaces 14.1-14.6 are arranged on the base plane 12. Here, the resistance surfaces 14.1 and 14.2 are arranged at least partially in a common resistance plane E1 as a first pair of resistance surfaces. For example, the edge areas of the resistance surfaces 14.1 and 14.2 can also leave the plane E1.

[0032] As in Figure 4 As can be seen in FIG. 1 , the resistance plane E1 is arranged at an angle β relative to the base plane 12 and the plane E1 therefore intersects the base plane 12 at the straight line G1 . Figure 1 The angle β is not shown in FIG. The angle β is preferably less than 90° and is preferably in the range of 25° to 45°, particularly preferably in the range of 30° to 45°.

[0033] In the same way as the first pair of resistance surfaces, the second pair of resistance surfaces 14.3 and 14.4 and the third pair of resistance surfaces 14.5 and 14.6 are arranged in a plane E2 or E3 which forms an angle β with the base plane 12, thereby forming straight lines G2 and G3. The angle β can be selected identically or differently for each plane E1, E2 and E3.

[0034] The resistance surfaces 14.1-14.6 are arranged on the base plane 12 in such a way that the generated straight lines G1-G3 have intersection points S1-S3 with each other at least in pairs, with an acute angle of intersection α. ​​The intersection point S1 is formed, for example, by the intersecting straight lines G1 and G3 and is arranged here between the resistance surfaces 14.1 and 14.2 and 14.5 and 14.6. In addition, the intersection point S2 is formed, for example, by the intersecting straight lines G2 and G3 and is arranged here between the resistance surfaces 14.3 and 14.4 and 14.5 and 14.6. Finally, the intersection point S3 is formed, for example, by the intersecting straight lines G1 and G2 and is arranged here between the resistance surfaces 14.1 and 14.2 and 14.3 and 14.4.

[0035] As in Figure 1 As can be seen in FIG. 1 , three equal acute intersection angles α are formed between the straight lines G1 and G2, G2 and G3, and G1 and G3. In the preferred case of the three pairs of resistance surfaces, the acute intersection angle α is always 60°.

[0036] The equal acute angles of intersection α ensure that the forces occurring during vehicle operation are transmitted in a uniformly distributed manner via the resistance surfaces 14.1-14.6 of the base 10. The resistance surfaces 14.1-14.6 can absorb or transmit the occurring forces particularly well due to their planar design and can be designed to save space compared to interlocking elements. Vibrations during driving operation are thus minimized.

[0037] It is also conceivable that the base 10 has more than three pairs of resistance surfaces, the resulting acute angles α being always equal to ensure a symmetrical force distribution. As mentioned at the beginning, a tolerance range of ±3° is also considered here.

[0038] Furthermore, it is also conceivable that the resistance surfaces 14.1-14.6 are arranged so that the generated straight lines G1-G3 all intersect at a common intersection point S (not shown). Figure 2 In the case of the circular arrangement shown, the spacing of the resistance surfaces 14.1-14.6 on the circumference is increased, which constitutes an alternative arrangement for uniform force transmission when the acute intersection angles α are equal.

[0039] Preferably, a pair of resistance surfaces is assigned to the vehicle in the X direction, Figure 1 These may be, for example, resistance surfaces 14.5 and 14.6.

[0040] In the installed state of the base in the vehicle, the resistance surfaces 14.5 and 14.6 are provided for absorbing the impact forces caused by a collision in the vehicle's X direction. The impact forces may be caused, for example, by the head of a vehicle occupant accelerating forwards striking the interior rearview mirror. As a result, the impact forces in the vehicle's X direction can be absorbed particularly well by the base 10 up to a certain threshold value. The two resistance surfaces 14.5 and 14.6 are arranged here by selecting the angle β so that when the impact forces exceed the threshold value, the mirror foot 20 with the interior rearview mirror separates from the base 10, thereby preventing head injuries.

[0041] Likewise, the pairs of resistance surfaces 14.1 and 14.2 as well as 14.3 and 14.4 can be assigned to the vehicle Y direction so that in the same way the mirror foot 20 with the interior rearview mirror can be released from the base 10 when a collision force occurs in the vehicle Y direction. Here, the forces can act and be absorbed in the XY plane.

[0042] In addition, Figure 1 As can be seen in the figure, a through hole 16.1 is formed in the side wall 16 of the base 10. A clip 30 can be inserted through the through hole 16.1, and the movement of the clip is limited by at least one limiting element 16.2 in the base 10. The clip 30 is designed so that in the locked position on the limiting element 16.2, the flexible element of the clip 30 engages with the base 10. A limiting band (not shown) is fixed to one end of the clip, which is in turn fixed to the temple 20. In the event of a vehicle collision, the temple 20 with the interior rearview mirror is separated from the base 10 and the movement of the temple can be limited by the limiting band.

[0043] Figure 2 A schematic perspective view of an embodiment of a mirror foot 20 according to the present invention is shown, which is used to be connected to a base 10 and to be used to arrange an interior rearview mirror on the windshield of a motor vehicle. The mirror foot 20 is a counterpart for the base 10 and has a plane, straight line and angle arrangement corresponding to the base 10.

[0044] In this case, the temple 20 preferably extends at least partially in the temple plane 22. Figure 2 As shown, the temple plane 22 can be formed by the surface of the temple 20. However, it is also conceivable that the temple plane 22 is only defined by an abstract plane. Preferably, parts of the temple 20 extend into this plane or at least intersect this plane.

[0045] Six fixing surfaces 24.1-24.6 are provided on the mirror foot plane 22. Here, the fixing surfaces 24.1 and 24.2 are at least partially provided in a common fixing plane F3 as a first pair of fixing surfaces. For example, the edge regions of the fixing surfaces 24.1 and 24.2 may also leave the plane F3.

[0046] In contrast to the base 10, Figure 2 The middle fixing surface 24.1-24.6 extends from the mirror foot plane 22 toward the rest of the main body of the mirror foot 20, and Figure 1 In the base 10 in FIG. 1 , the resistance surfaces 14.1-14.6 extend from the base plane 12 away from the rest of the body of the base 10. Thus, the resistance surfaces 14.1-14.6 and the fixing surfaces 24.1-24.6 can be locked in the installed state according to the key lock principle. Figure 3 As shown, they are adjacent to each other.

[0047] Therefore, all the advantageous features of the base 10 are also applicable to the temple 20 and can be transferred to the temple:

[0048] As in Figure 2 It can also be seen that, by way of example, the fixing plane F1 is arranged at a right angle β' relative to the temple plane 22 and the plane F1 therefore intersects the temple plane 22 at a straight line G1'. Preferably, the angle β' is less than 90° and is preferably in the range of 25° to 45°, particularly preferably in the range of 30° to 45°.

[0049] In the same way as the first pair of fixing surfaces, the second pair of fixing surfaces 24.3 and 24.4 and the third pair of fixing surfaces 24.5 and 24.6 are arranged in a plane F2 or F1 that forms an angle β' with the temple plane 22 (the angle β' of these pairs is not shown), thereby forming straight lines G2' and G3'. β' can be selected identically or differently for each plane F1, F2 and F3. Preferably, β'=β is selected in each case so that the resistance surfaces 14.1-14.6 and the fixing surfaces 24.1-24.6 are as shown in FIG. Figure 3 As shown in , they are better attached to each other.

[0050] The fixing surfaces 24.1-24.6 are arranged on the temple plane 22 in such a way that the generated straight lines G1'-G3' have intersection points S1'-S3' with each other at least in pairs, with an acute angle of intersection α. ​​The intersection point S1' is formed, for example, by the intersecting straight lines G1' and G2' and is arranged here between the fixing surfaces 24.5 and 24.6 and 24.3 and 24.4. In addition, for example, the intersection point S2' is formed by the intersecting straight lines G2' and G3' and is arranged here between the fixing surfaces 24.3 and 24.4 and 24.1 and 24.2. Finally, for example, the intersection point S3' is formed by the intersecting straight lines G1' and G3' and is arranged here between the fixing surfaces 24.1 and 24.2 and 24.5 and 24.6.

[0051] As in Figure 2 As can be seen in FIG. 1 , three equal acute intersection angles α are formed between the straight lines G1′ and G2′, G2′ and G3′, and G1′ and G3′. In the preferred case of the three pairs of fixing surfaces, the acute intersection angle α is always 60°.

[0052] The equal acute angles of intersection α ensure that the forces occurring during vehicle operation are transmitted uniformly distributed via the fastening surfaces 24.1-24.6 of the mirror foot 20. The fastening surfaces 24.1-24.6 can absorb or transmit the occurring forces particularly well due to their planar design and can be designed to save space compared to interlocking elements. Vibrations during driving operation are thus minimized.

[0053] It is also conceivable that the mirror foot 20 has more than three pairs of fixing surfaces, and the acute angles of intersection α generated are always equal to ensure symmetrical force distribution. As mentioned at the beginning, a tolerance range of ±3° is also considered here.

[0054] Furthermore, it is also conceivable that the fixing surfaces 24.1-24.6 are arranged in such a way that the generated straight lines G1'-G3' all intersect at a common intersection point S (not shown). Figure 2 In the case of the circular arrangement shown, the spacing of the fastening surfaces 24 . 1 - 24 . 6 on the circumference is increased, which constitutes an alternative arrangement for a uniform force transmission when the acute intersection angles α are equal.

[0055] Preferably, a pair of fixed surfaces are assigned to the vehicle X direction, Figure 1 These may be, for example, the fastening surfaces 24.5 and 24.6.

[0056] In the installed state of the base in the vehicle, the fastening surfaces 24.5 and 24.6 are provided for absorbing collision forces caused by a collision in the vehicle X direction. The collision forces can be caused, for example, by the head of a vehicle occupant accelerating forwards striking the interior rearview mirror. As a result, collision forces in the vehicle X direction can be absorbed particularly well by the mirror foot 20 up to a certain threshold value. The two fastening surfaces 24.5 and 24.6 are arranged here by selecting the angle β' so that when the collision force exceeds the threshold value, the mirror foot 20 with the interior rearview mirror is separated from the base 10, thereby preventing head injuries.

[0057] Likewise, the paired fixing surfaces 24.1 and 24.2 as well as 24.3 and 24.4 can be assigned to the vehicle Y direction so that in the same way the mirror foot 20 with the interior rearview mirror can be allowed to fall off from the base 10 when a collision force occurs in the vehicle Y direction. Here, the force can act and be absorbed in the XY plane.

[0058] Figure 3 A schematic side view of an embodiment of a mounting assembly according to the invention is shown, the mounting assembly having Figure 1 Base 10 and Figure 2The bottom 10.1 of the base 10 is arranged on the windshield of the vehicle. It is conceivable that the diameter of the bottom 10.1 is in the range of 30 mm to 55 mm, preferably in the range of 40 mm to 55 mm, and particularly preferably 40 mm. This compact design of the base 10 is achieved by providing the resistance surfaces 14.1-14.6 according to the invention.

[0059] Generally speaking, in the final installed state, each resistance surface 14 and a fixing surface 24 are in contact with each other. Figure 3 As can be seen in FIG. 1 , the resistance surface 14.5 and the fixing surface 24.5 are in contact with each other. Here, the base 10 and the temple 20 are held together and pressed against each other by means of a torsion spring 40. Generally speaking, the torsion spring 40 can be arranged on the rotation axis between the base 10 and the temple 20 in a known manner and can also be connected to the temple 20 first.

[0060] The torsion spring 40 comprises at least two mutually opposite engagement arms 40.1. The engagement arms 40.1 are provided for engagement with the engagement region 18 of the base 10 during installation and in the final installed state. Figure 4 and Figure 5 To explain.

[0061] Particularly preferred Figure 3 A sensor (not shown) for being arranged on a vehicle windshield, such as a rain sensor, is provided in the mounting assembly. In the final mounted state, the sensor and the base 10 are arranged at different positions on the windshield, preferably side by side. Since the sensor is not arranged on the windshield inside the base 10, but outside the base 10, the available construction space can be used in an advantageous manner for the arrangement of the resistance surfaces 14.1-14.6 and does not have to be used for the sensor. As a result, a flatter construction height or a smaller diameter of the bottom 10.1 of the base can be achieved.

[0062] Figure 4 A schematic perspective view shows an embodiment of a base 10 according to the invention with a torsion spring 40 in a pre-fixed position during installation, wherein the temple 20 is not shown for the sake of better illustration.

[0063] exist Figure 4 In a preferred embodiment of the torsion spring 40, for example, it comprises four engagement arms 40.1, which are respectively engaged in the engagement region 18 of the base 10. However, embodiments with a different number of engagement arms 40.1 are also conceivable.

[0064] The engagement region 18 is arranged on the side wall 16 of the base and has at least two recesses 18.1, which are arranged between fixing elements 18.3 protruding from the side wall 16. In addition, a pre-fixing rib 18 is provided for each recess 18.1. The pre-fixing rib 18.2 is, for example, Figure 4 1 and the bottom 10.1 of the base 10. Preferably, the fixing element 18.3 here protrudes further from the side wall 16 than the pre-fixing rib 18.2.

[0065] During installation, the engaging arm 40.1 in the pre-fixing position due to the recess 18.1 does not act on the fixing element 18.3, but on the pre-fixing rib 18.2. Thus, before the mirror foot 20 is rotated to its final installation position, the mirror foot 20 is pre-fixed on the pre-fixing rib by means of the torsion spring 40 during installation.

[0066] Base 10 and mirror foot 20 can be preferably designed like this, make directly reach three resistance surfaces 14 when installing and these three resistance surfaces do not cause resistance during installation.By crossing over and reaching other three resistance surfaces 14 when installing, define installation force resistance thus.

[0067] Here, the pre-fixing surface 26 of the mirror foot 20 is respectively assigned to the boosting surface 15 of the base 10 in the pre-fixing position. Figure 2 and Figure 3 As can be seen in FIG. 1 , the pre-fixing surface 26 is respectively opposite to one of the fixing surfaces 24.1-24.6, so that the two surfaces have an angle with each other. Figure 4 and Figure 5 It can be seen in FIG. 1 that the thrust surface 15 is respectively opposite one of the resistance surfaces 14 . 1 - 14 . 6 , so that the two surfaces are at an angle to each other.

[0068] Figure 5 A schematic perspective view shows an embodiment of a base 10 according to the invention with a torsion spring 40 in the final mounted state, wherein the temple 20 is not shown for the sake of better illustration.

[0069] In from Figure 4 The pre-fixed position in Figure 5 When the final installation state is transitioned, by rotating the torsion spring 40, for example, one of the pre-fixing surfaces 26 is rotated from its corresponding boosting surface 15 to the corresponding resistance surface 14.1-14.6, so that in the final installation state, the corresponding fixing surface 24.1-24.6 is abutted against the corresponding resistance surface 14.1-14.6 and the elastic force of the torsion spring 40 is as follows. Figure 3 It can be seen that it is fixed to the resistance surface.

[0070] In principle, it is conceivable that the three thrust surfaces 15 are respectively crossed by the corresponding pre-fixing surface 26, thereby generating a resistance to the installation force. This is preferably the case with the thrust surfaces 15.2, 15.3 and 15.6. In other words, the pre-fixing surface 26 thus slides over the corresponding thrust surface 15 to the final installation state, in which the fixing surfaces 24.1-24.6 are in contact with the corresponding resistance surfaces 14.1-14.6.

[0071] Alternatively or additionally, when rotating from the pre-fixing position to the final installation state, if its pre-fixing surface 26 does not pass over the boosting surface 15, the corresponding fixing surface 24.1-24.6 can be rotated toward its corresponding resistance surface 14.1-14.6, so that they are in contact with each other and fixed by the elastic force of the torsion spring 40. This is preferably the case in the fixing surfaces 24.1, 24.4 and 24.5.

[0072] During this rotation process, the engagement arms 40.1 are also respectively rotated from the pre-fixing ribs 18.2 to the corresponding fixing elements 18.3 and engage with the fixing elements, thereby generating a spring force.

[0073] In general, other shapes are also conceivable for the resistance surfaces 14.1-14.6, the thrust surfaces 15, the fixing surfaces 24.1-24.2 and the pre-fixing surface 26. In principle, all of the above-mentioned elements and surfaces are arranged and oriented in their shape, height and angles in such a way that the requirements resulting from the corresponding standards such as FMVSS 571.111 and ECE-R46 are met.
