Definitions
- the invention relates to sensors intended to be mounted on a bodywork part of a motor vehicle such as a front or rear bumper.
- the various sensors arranged on the body parts are held in position at the level of the latter by means of supports fixed to the body parts, for example by welding or gluing.
- the latest generations of sensors are delivered with a seal.
- the latter includes lateral bosses. It is therefore necessary that the seal is compressed when the sensors are mounted on the body parts, in order to ensure a good seal of the assembly.
- the support is fixed to the internal face of a bodywork part (not visible to a user when the bodywork part and mounted on a motor vehicle) and the sensor is placed against the internal face of the body part, the seal being compressed between the sensor and the internal face of the body part.
- This force which can be of an intensity approximately equal to 30daN, can lead to limiting the possibilities of fixing the sensor supports. Indeed, the pressure exerted locally by the sensor on the bodywork part leads to the appearance of stresses in the areas in which the sensor support is fixed to the bodywork part.
- An object of the invention is to provide a sensor support for a piece of body making it possible to respond to the aforementioned stress problems with the aid of a more satisfactory solution than that of the prior art.
- the invention relates to a set of a sensor support for a bodywork part and a sensor, the sensor support comprising:
- the collar constituting a bearing surface of a compressed sensor seal against the collar of the sensor support, the sensor support taking up all the forces resulting from pressure exerted by the seal on the flange.
- a sensor support capable of supporting only the pressure exerted by a sensor mounted on a body part, which avoids the exercise of pressure by the sensor on the body part.
- the flange which is an integral part of the sensor support, is not visible from outside the vehicle when the bodywork part is mounted on a vehicle. This makes it possible to overcome the constraints of multiplication of the parts to be handled (absence of a need for painting, simplified storage, etc.).
- the collar came integrally with the fixing zone and the reception zone, for example by molding,
- the collar extends from one end of the reception area opposite to one end of the reception zone from which the sensor can be inserted, the reception zone is tubular, the collar s 'extending in a direction perpendicular to an axis of revolution of the reception area,
- the sensor support comprises at least one fixing element holding the sensor in position in the sensor support,
- the fixing element compresses the seal against the flange
- the collar is of a thickness greater than or equal to 1 mm.
- the sensor support comprises the fixing element, the sensor comprising at least one bearing surface in contact with the fixing element, and
- the senor is compressed between the fixing elements and the flange.
- the invention also relates to a bodywork part comprising:
- the bodywork part according to the invention may include one or more of the following characteristics:
- the main body comprises a through orifice, one end of the sensor being flush with an external face of the main body,
- the collar of the sensor support is distant from the internal face of the main body
- the sensor support is glued or welded to the internal face of the main body.
- FIG. 1 is a perspective view of a portion of a bodywork part on which is fixed an assembly consisting of a sensor support and of a sensor according to the invention
- FIG. 2 is a sectional view of the portion of the bodywork part of FIG. 1 according to a cutting plane l-l, and
- FIG. 3 is a sectional view of the portion of bodywork of Figure 1 along a section plane II-II.
- a portion of a bodywork part 2 comprising a main body 4 can be made of plastic, for example in a thermoplastic material, for example by injection molding.
- This main body 4 includes an internal face 6 and an external face 8.
- the internal face means the face of the main body 4 which is not visible from the outside of a vehicle on which the part is mounted. bodywork 2.
- the external face means the face of the main body 4 which is visible from the outside of a vehicle on which the bodywork part 2 is mounted.
- An assembly 10 consisting of a sensor 12 and a sensor support 14 is fixed to the main body 4, more particularly on its internal face 6.
- the sensor 12 can for example be an AAS type sensor. This type of sensor is known to those skilled in the art and its internal architecture will not be the subject of a detailed description here.
- the main body 4 includes a through hole in which the sensor 12 extends, one end 16 (for example the protective screen of an AAS sensor) of the sensor 12 can be flush with the external face 8 of the body main 4 (the thickness of the bodywork part 2 is then reduced locally compared with the solutions of the prior art).
- one end 16 for example the protective screen of an AAS sensor
- the sensor 12 includes a seal 18 for sealing at the through hole in the main body 4 for mounting the sensor 12. To ensure this seal, the seal 18 extends to through the through hole and is compressed at the level of the sensor support 14.
- the sensor support 14 comprises two fixing zones 20 making it possible to fix the sensor support 14 to the main body 4, for example by welding (for example using a sonotrode) or also by gluing (presence of two glue strips 21 visible in FIG. 2) from the latter to the main body 4.
- the number and the shape of the fixing zones 20 can obviously vary.
- the sensor support also includes a reception area 22 into which at least part of the sensor 12 can be inserted.
- the latter can be of different shapes, for example of tubular shape in the figures, and have at least part of its inner surface of a shape complementary to that of the part of the sensor 12 placed inside the reception area 22 .
- the reception area 22 may, as shown in the figures, extend perpendicular to the attachment zones 20, the attachment zones 20 extending in the example illustrated on either side of the reception area 22 from the outside of the latter.
- the angle formed by the reception zone 22 and the fixing zones 20 may not be equal to 90 °.
- the sensor support 14 further comprises a flange 24 adapted to collaborate with the seal 18. More specifically, the seal 18 can be compressed against the flange 24 to seal the assembly shown in the figures. This means that the seal 18 is only compressed against the collar, more precisely between a shoulder 13 of the sensor 12 and the collar 24.
- the sensor 12 exerts pressure on the internal face 6 of the main body 4, the sensor support 14 taking up all the forces undergone by the flange 24 when the seal 18 exerts pressure on the latter (there is no has no force exerted locally and directly by the seal 18 at the internal face 6 as in the prior art), due to the need to compress the seal 18 to seal the bodywork part 2.
- L exercise of local and direct pressure by a seal on a bodywork part as is the case in the prior art harms the holding over time of the quality of the fixing of a sensor support on a workpiece bodywork (the force exerted by the seal 18 being substantially perpendicular to the plane in which the interface extends between the fixing zones 20 and the main body 4).
- Such a configuration (the gasket 18 compressed against the flange 24) therefore overcomes the need to limit the number of methods of fixing the sensor support 14 to the internal face 6 of the main body 4 (front be strong enough not to be impacted by a force generated by a sensor which would be directly mounted on the main body 4).
- the collar 24 has a thickness greater than or equal to 1 mm.
- the flange 24 is located at a distance (distant) from the internal face 6 of the main body 4.
- the flange 24, in this case in figure is not in contact with the internal face 6 of the main body 4, which makes it possible to avoid the exertion of pressure by the sensor 12 on the main body 4. An isolated assembly 10 is therefore obtained relative to the main body 4.
- the fixing zones 20, the reception zone 22 and the flange 24 have come in one piece, for example by molding.
- the latter extends inside the reception area 22. It can extend, as shown in Figures 2 and 3 , at one end of the latter opposite to the insertion end of the sensor 12 in the reception area 22. It is possible to place this flange 24 at a different level inside the reception area 22.
- the flange 24 may extend in a direction perpendicular to a longitudinal axis of the reception area 22.
- the reception zone 22 has a cylindrical shape, the flange 24 s extending perpendicularly to an axis of revolution of the reception area 22.
- the sensor support 14 may comprise at least one fixing element 26 making it possible to hold the sensor 12 in position inside the reception area 22
- the figures illustrate an embodiment with two fixing elements 26. This case will be described later.
- the fastening elements 26 can be in contact with at least one bearing surface 28 (two in the embodiment shown in the figures and described below) present at the level of the sensor 12.
- These fastening elements 26 can be deformable elastically in order to be able to insert the sensor 12 into the reception zone 22 and then to be in contact with the bearing surfaces 28.
- the dimensioning of the reception area 22 and of the sensor 12 is carried out to ensure that, once the sensor 12 is mounted on the sensor support 14, the fastening elements 26 allow the seal 18 to be compressed against the flange 24.
- the sensor 12 is compressed between the fastening elements 26 and the flange 24.
- This is represented by the arrows 30 illustrating the force exerted by the fastening elements 26 on the sensor 12, in this example on the bearing surfaces 28.
- the arrows 32 illustrate the reaction force exerted by the flange 24 on the seal 18. These two forces extend in parallel directions, in opposite directions and are of equal intensity. Materials used for manufacturing of the flange 24 and the fastening elements 26 are chosen in order to be able to ensure optimal compression over time (absence of deformation of the flange 24 or of the fastening elements 26 over time).
- fastening elements have a shape different from that illustrated in the figures. It could for example be a cap covering the sensor.
- the number of fasteners may also vary. The same applies to the support surfaces.
- reception area may have a shape different from that illustrated in the figures.
- the sensor support can in turn be fixed to the main body by a process other than gluing or welding.
- a sensor support may include several reception areas in order to support several sensors.
- the main body may include several through holes (as many as there are sensors).
