Description

Description
Title
Mounting for a sensor Prior art
The present invention relates to a mounting for a sensor. In particular, the invention relates to a mounting for an ultrasound sensor useable on a vehicle. A mounting for a sensor is known for example from US 8,986,478 B2. The mounting disclosed therein is formed circularly and comprises two annular elevations on a mounting face, which are to be attached to a vehicle covering by torsional ultrasound welding. However, the use of a plurality of annular elevations of this type has the drawback that different thermal expansions of the covering and the sensor mounting can lead to warping, making the service life of a connection of this type limited. Furthermore, waves generated by an ultrasound sensor held by the mounting cannot be damped by the two elevations on the mounting face, and as a result a large region of the covering is set in oscillation. This is contrary in particular to the purpose of use of ultrasound sensors, which require a locally limited oscillation for a measurement. A similar sensor mounting to what is described above is known from WO 2011/101412 A1.
Disclosure of the invention
The mounting according to the invention for a sensor advantageously makes it possible to reduce tensions which may occur within a connection site of the mounting to a covering. Furthermore, the mounting according to the invention makes it possible to damp oscillation waves proceeding from a sensor held by the mounting. The mounting proposed by the invention for a sensor has a mounting face, wherein the mounting face is used to attach the mounting to a covering of a vehicle. The covering of the vehicle is in particular a bumper of the vehicle, the sensor advantageously being an acoustic sensor, in particular an ultrasound sensor, in such a way that an ultrasound sensor can be fastened to the vehicle by means of the mounting. The mounting face comprises a sensor opening, a first fastening elevation and a plurality of second fastening elevations. The first fastening elevation and the second fastening elevations are set up for fastening to the covering. In particular, it is provided that the first fastening elevation and the plurality of second fastening elevations are positioned flat against the covering. The sensor opening serves to accommodate the sensor. In particular, it is provided that the mounting comprises additional holding elements, in particular arranged perpendicular to the mounting face, it being possible for the sensor to be held by means of the holding elements. The first mounting elevation fully encloses the sensor opening. In particular, the first fastening elevation is arranged continuously around the sensor opening. There is thus a sealing effect as a result of the first fastening elevation, since penetration of foreign bodies, such as dirt in particular, is prevented by the advantageous flat positioning of the first fastening elevation against the covering. The sensor is therefore shielded against external influences. The second fastening elevations merely partially enclose the sensor opening, and are in particular arranged between the first fastening elevation and the sensor opening. In this context, "partially enclosing" means in particular that the second fastening elevations do not extend fully around the sensor opening. The second fastening elevations thus span an angular range of less than 360° about a centre point of the sensor opening. Particularly advantageously, the second fastening elevations are individual portions of a geometric shape enclosing the sensor opening, such as in particular individual segments of a circular path enclosing the sensor opening.
The dependent claims disclose preferred developments of the invention.
Preferably, the first fastening elevation is arranged on an outer periphery of the mounting face. The second fastening elevations are located between the first fastening elevation and the sensor opening. Thus, the first fastening elevation forms a termination of the mounting face. In this way, in particular no foreign bodies can be introduced between the mounting face and the covering, making possible a stable and reliable connection between the mounting and the covering on the one hand and making possible reliable operation of the sensor on the other hand. Furthermore, as a result of an arrangement of this type, the first fastening elevation has maximum dimensions, making secure, reliable holding achievable.
Preferably, the mounting face is configured in such a way that it has a circular or elliptical periphery. Thus, it is preferably provided that the mounting face is a circular or elliptical face. In a particularly advantageous embodiment, the mounting face is circular or elliptical, the first fastening elevation being a peripheral ring on the mounting face. The second fastening elevations are advantageously individual ring segments, which partially extend around the sensor opening. Particularly preferably, it is further provided that the second fastening elevations are arranged at random between the sensor opening and the first fastening elevation.
Advantageously, the second fastening elevations are separated from one another by channels extending radially with respect to the sensor opening. The channels preferably extend regularly about the sensor opening. Furthermore, the channels preferably have the same dimensions. A regular arrangement of the second fastening elevations is thus provided. This makes possible a secure, reliable attachment of the mounting to the covering on the one hand, and the propagation of oscillation waves proceeding from the sensor is damped by the second fastening elevations on the other hand. The second fastening elevations are thus preferably attached within adjacently arranged circle segments and/or ellipse segments. Thus, the shape of the mounting face and/or of the first fastening elevation is insignificant. The circle sectors and/or ellipse sectors in particular have the same size or the same solid angle, particularly advantageously every second fastening elevation being a ring segment within each circle sector. The individual circle sectors and/or ellipse sectors comprise ring segments of at least one ring.
The second fastening elevations preferably each have a contact area. The contact areas can in particular be applied to the covering. It is preferably provided that the contact area increases with increasing distance of the associated second fastening from the sensor opening. Thus, an optimum force distribution when fastening the mounting to the covering can be ensured. At the same time, this results in an advantageous damping characteristic of the mounting. As a result of the mutually separated ring segments of the second fastening plane, temporary deformations of the covering, such as occur in particular in the case of blunt impact on a bumper, can be absorbed better by the covering. The configuration according to the invention of the mounting thus on the one hand enables sufficient reinforcement of the covering such that at the fastened sensors thereof, in particular ultrasound sensors, the functionality thereof can be exercised reliably even through the covering, and that tensions, occurring in particular as a result of external force influences and/or of changes in temperature in the event of different material properties, can be compensated on the other hand.
The second fastening elevations are in particular formed point-shaped or strip-shaped. The strip shape makes flat positioning possible, making possible secure holding of the mounting on the covering. The point shape makes it possible to produce individual support sites in a targeted manner.
The first fastening elevations and/or the second fastening elevations advantageously have a height of 1 mm to 10 mm. Particularly advantageously, the first fastening elevations and/or the second fastening elevations have a height of 4 mm to 7 mm. The height is in particular a measure of the elevation of the first fastening elevation and/or second fastening elevation above the rest of the mounting face. As a result of a height of this type, the first fastening elevations and the second fastening elevations are offset considerably from the rest of the mounting face. Fastening merely at the first fastening elevation and the second fastening elevations is thus possible. At the same time, an empty space between the mounting and the covering is minimised.
The invention further relates to an arrangement comprising a mounting as disclosed above and a covering. It is provided that a surface of the first fastening elevation and a surface of the second fastening elevations correspond to a surface of the covering. Particularly advantageously, the mounting, in particular the respective surfaces of the first fastening elevation and the second fastening elevations, and the covering are materially connected. Secure and reliable holding of the mounting on the covering is thus provided, the material connection making the connection highly inconspicuous. In particular, the presence of the mounting is not perceptible from an opposite surface of the covering.
The mounting is in particular welded to the covering. Particularly advantageously, the first fastening elevation and the plurality of second fastening elevations are welded to the covering. The welding preferably takes place by torsional welding, in particular torsional ultrasound welding.
Alternatively or additionally, the first fastening elevations and the second fastening elevations are glued and/or otherwise inseparably connected to the covering. Thus, in particular the heating of the covering and mounting caused by the welding is avoided.
By means of the second fastening elevations, the formation of oscillation waves proceeding from the sensor can advantageously be damped or prevented. The oscillation waves occur in particular at the operating frequency of the sensor if the sensor is an acoustic sensor, in particular an ultrasound sensor. As a result of the arrangement and dimensions of the second fastening elevations, a damping characteristic of the mounting can preferably be set in such a way that oscillation waves of this type can be damped, in particular completely. Thus, local radiation of waves by the sensor is made possible, making it possible to take an exact measurement using the sensor.
Brief description of the drawings
In the following, embodiments of the invention are disclosed in detail with reference to the accompanying drawings, in which:
Fig. 1 is a schematic drawing of a mounting in accordance with a first embodiment of the invention, which is fastened to a covering,
Fig. 2 is a schematic drawing of the mounting face of the mounting in accordance with the first embodiment of the invention,
Fig. 3 is a schematic drawing of the mounting face of a mounting in accordance with a second embodiment of the invention, and
Fig. 4 is a schematic drawing of the mounting face of a mounting in accordance with a third embodiment of the invention.
Embodiments of the invention
Fig. 1 schematically shows a mounting 1, which is fastened to a covering 2. The mounting 1 serves in particular to accommodate a sensor 3. The sensor 3 is in particular an ultrasound sensor. The covering 2 is preferably a bumper of a vehicle. Thus, the sensor 3 can preferably be attached to the vehicle by means of the mounting 1.
In the preferred embodiment thereof as an ultrasound sensor, the sensor 3 emits acoustic signals, which are reflected by an environment of the sensor 3, so as thus to measure the environment. In this way, distance information in particular can be obtained. So as to be able to carry out high-quality measurements using the sensor 3, it is necessary for the sensor 3 only to emit waves in defined directions. In particular, large-area oscillation of the covering 2 should be avoided. The mounting 1 has a mounting face 8 by means of which the mounting 1 can be attached to the covering 2. The mounting face 8 comprises a sensor opening 6 in which the sensor 3 is arranged. The mounting face 8 also comprises a first fastening elevation 4, which fully encloses the sensor opening 6, and a plurality of second fastening elevations 5. The arrangement of the first fastening elevation 4 and the second fastening elevations 5 is shown in Fig. 2.
Fig. 2 is a schematic plan view of the mounting face 8 of the mounting 1. It can be seen that the mounting face 8 has a circular periphery, the first fastening elevation 4 having an annular shape. As can be seen from Fig. 1 and 2, the first fastening elevation 4 is attached on the outer periphery of the mounting face 8. The first fastening elevation 4 thus forms a termination of the mounting face 8. Furthermore, the first fastening elevation 4 fully encloses the sensor opening 6. It is thus ensured that no foreign bodies, in particular no dirt, from the environment can reach the sensor opening 6 and thus the sensor 3. The first fastening elevation 4 thus has a sealing effect.
Furthermore, as a result of the annular configuration of the first fastening elevation 4, there is planar contact between the mounting 1 and the covering 2. Thus, the mounting 1 can be stably and reliably connected to the covering 2.
The second fastening elevations 5 are each formed as a ring segment, and partially enclose the sensor opening 6. In the first embodiment shown in Fig. 2, the second fastening elevations 5 are arranged apparently at random between the sensor opening 6 and the first fastening elevation 4. It is merely provided that a contact area 9 of the second fastening elevations 5 increases with increasing distance from the sensor opening 6. In a preferred development, the planar distribution in particular of the contact areas 9 of the fastening elevations 5 is selected in such a way that oscillations introduced from the sensor 3 into the covering 2 do not propagate along the covering 2. Thus, a possibility of secure and stable connection to the covering 2 is provided. A distance from the sensor opening 6 can be determined in particular along a radius 10. It is also provided that the second fastening elevations 5, formed as ring segments, always extend perpendicular to the associated radius 10, providing an arc shape.
The second fastening elevations 5 increase the contact area between the covering 4 and the mounting 1 on the one hand, and make it possible to damp waves which propagate along the mounting face 8 starting from the sensor 3 on the other hand. Waves of this type are undesirable during the operation of the sensor 3, and lead to distortions of the measurement result of the sensor 3. Thus, the arrangement of the second fastening elevations 5 prevents oscillation waves from being able to form at the operating frequency of the sensor 3.
The mounting 1 is advantageously fastened to the covering 2 by torsional ultrasound welding. The first fastening elevation 4 and the second fastening elevations 5 are fused on locally, in such a way that they can be connected to the covering 2. The fusing takes place in particular by way of a vibrational movement about a central axis 20 (cf. Fig. 1) of the mounting 1. As an alternative, it is preferably provided that the first fastening elevation 4 and the second fastening elevations 5 are glued to the covering 2. According to the invention, however, other forms of connection are also possible. Forms of connection which cannot be released without being destroyed are particularly suitable.
Fig. 3 shows the mounting face 8 of a mounting 1 in accordance with a second embodiment of the invention. In the second embodiment of the invention, the mounting face 8 has a plurality of circle sectors 7, the circle sectors 7 being formed by ring segments which are mutually separated by channels 11 extending radially with respect to the sensor opening 6, and the ring segments being the second fastening elevations 5. Thus, there is a regular arrangement of the second fastening elevations 5, increasing the stability of the fastening of the mounting 1 on the covering 2 on the one hand, and improving a damping characteristic of the mounting 1 for waves extending along the mounting face 8 proceeding from the sensor 3 on the other hand. These channels 11 make it possible to absorb deformations acting on the vehicle covering 2 in a targeted manner. Thus, a bumper used as a covering 2 and the mounting 1 fastened thereto will deform predominantly along the channels 11 at a distance from the connection between the mounting 1 and the covering 2 by means of the second fastening elevations 5.
Fig. 4 schematically shows a third embodiment of the mounting 1. The mounting face 8 and the sensor opening 6 each have an elliptical periphery. Thus, the first fastening elevation 4 is also shaped elliptically. It can be seen that different membrane shapes of sensors 3 configured as ultrasound sensors can be used. As a result of the elliptical shape of the mounting face 8, the damping characteristic of the mounting 1 is in particular adapted to an elliptically shaped membrane of the sensor 3. As a result of the arrangement of the second fastening elevations 5, a directional characteristic of an acoustic sensor can be adapted appropriately to the requirements. Otherwise, the third embodiment corresponds to the first embodiment.
