Description

fluidic conduit system for a motor vehicle washing assembly.

The technical context of the present invention is that of washing assemblies for motor vehicles. More particularly, the invention relates to a male conductor of a fluidic conduit system, as well as to such a fluidic conduit system and an assembly method.

In the state of the art, washing assemblies are known on board motor vehicles and which make it possible to clean the glass walls of the motor vehicle. It may in particular be a windshield or a rear window of the motor vehicle, a closing window of a lighting and/or signaling device, or even an optical surface of a sensor on board said motor vehicle, such as for example a laser remote sensing system.

Such washing assemblies are known comprising a reservoir for a cleaning liquid, fluid conduits making it possible to transport the cleaning liquid to nozzles for projecting said cleaning liquid towards the glass walls to be cleaned. In order to allow such projection, known washing assemblies include a pump allowing the fluid to move in the fluid conduits. Of course, taking into account the number of glass walls to be cleaned on a motor vehicle, the known cleaning assemblies comprise a network of fluidic conduits which extends through the motor vehicle, the network comprising male conductors capable of coupling with female conductors.

Such known male conductors thus comprise a cylindrical surface, one axial end of which is engaged and fitted into a cylindrical surface complementary to the female conductor. It is thus possible to produce an extension of the fluid conduit, from the female conductor to the male conductor, or vice versa, and thus construct the network of fluid conduits according to an expected geometry and/or dimensions.

A known disadvantage of known male leads is the lack of visibility when mating.

Another known disadvantage lies in the lack of benchmarks allowing the quality of the coupling made to be checked. Indeed, if the male conductor is not sufficiently engaged with the female conductor, then there is a risk of the female conductor being torn off and uncoupled from the male conductor. Conversely, if the male conductor is too engaged in the female conductor, then there is a risk of tearing and damage to the female conductor.

The object of the present invention is to propose a new male conductor in order to at least largely respond to the previous problems and also to lead to other advantages.

Another aim of the invention is to facilitate the coupling of a male conductor with a female conductor.

Another aim of the invention is to avoid uncontrolled tearing of the female conductor fitted onto the male conductor.

Another aim of the invention is to avoid damage to the female conductor during its coupling with the male conductor.

According to a first aspect of the invention, at least one of the aforementioned objectives is achieved with a male conductor of a system of fluidic conduits comprising the male conductor and a female conductor with which the male conductor is intended to be coupled, the male conductor comprising:

- a hollow cylindrical surface extending along a specific elongation axis;

- a stopper configured to achieve an axial stop of the female conductor;

- a groove located between an axial end of the hollow cylindrical surface and the stop marking a minimum fitting.

In the context of the present invention, the hollow cylindrical surface is configured to allow the circulation of the fluid inside said hollow cylindrical surface. The hollow cylindrical bearing is configured to be able to collaborate with the female conductor by engagement of complementary shapes. In particular, a shape and dimensions of the hollow cylindrical surface are complementary to a shape and dimensions of the female conductor with which the male conductor is intended to collaborate, so as to authorize a fitting, preferably by force, of said female conductor onto said male conductor.

In the context of the present invention, the stopper forms an end stop of engagement for the female conductor on the male conductor. In other words, the stopper forms a maximum axial limit to the fitting of the female conductor onto the male conductor. The stop thus makes it possible to determine a maximum axial position of the female conductor coupled to the male conductor and for which the coupling is compliant and operational, that is to say for which the fluid circulation through the male conductor and the female conductor is made without loss.

In the context of the present invention, the groove forms a minimum engagement mark for the female conductor on the male conductor. In other words, the groove forms a minimum axial limit to the fitting of the female conductor onto the male conductor. The groove thus makes it possible to determine a minimum axial position of the female conductor coupled to the male conductor and for which the coupling is compliant and operational, that is to say for which the fluid circulation through the male conductor and the female conductor is carried out without loss.

In the context of the present invention, the fluid conduit is configured to allow the transport of a fluid, liquid or gas – through the male conductor and the female conductor. When the fluid is of the liquid type, then it is preferably of the type of a cleaning liquid such as used in a cleaning system for a motor vehicle. Such a cleaning liquid includes water and alcohol. When the fluid is of the gaseous type, then it preferably contains air as blown into a cleaning system for a motor vehicle.

In the context of the present invention, the proper elongation axis is the cylindrical axis of revolution of the hollow cylindrical conductor. It corresponds to the direction of elongation of the cylindrical conductor.

Thus, the male conductor conforming to the first aspect of the invention makes it easier to mate with a female conductor. In fact, the stop and the groove form two marks respectively for maximum engagement and minimum engagement of the male conductor in the female conductor. Therefore, the male conductor makes it possible to avoid uncontrolled tearing of the female conductor fitted onto the male conductor which would result from insufficient fitting and less than the axial position of the groove on the male conductor; and the male conductor also makes it possible to avoid damage to the female conductor during its coupling with the male conductor, resulting from excessive fitting of the female conductor beyond the stop of the male conductor.

The male conductor conforming to the first aspect of the invention advantageously comprises at least one of the improvements below, the technical characteristics forming these improvements being able to be taken alone or in combination:

- the male conductor has an entry chamfer formed on the axial end of the hollow cylindrical surface. This advantageous configuration thus makes it possible to facilitate the introduction of the male conductor into the female conductor with which it is intended to be coupled;

- the chamfer is formed on an exterior wall of the hollow cylindrical surface, the chamfer forming a clearance angle with said exterior wall. In other words, the outer wall of the cylindrical bearing has a beveled face oriented according to the clearance angle, at the level of the axial end of the hollow cylindrical bearing forming the male conductor;

- advantageously, the clearance angle is between 20° and 60°. Preferably, the clearance angle is equal to 45°;

- at its axial end, the hollow cylindrical surface has a rim which extends radially projecting relative to the hollow cylindrical surface, so as to have a diameter greater than that of said hollow cylindrical surface. The rim thus forms a protrusion which extends radially outside the hollow cylindrical surface, relative to the axis of proper elongation. This advantageous configuration prevents the female conductor with which the male conductor is intended to collaborate from unintentionally uncoupling. In other words, the edge of the male conductor forms an anti-tearing member for the female conductor;

- the stopper forms an axial shoulder for the female conductor with which the male conductor is intended to be coupled. By axial shoulder, we understand that the stopper makes it possible to place the female conductor in abutment, relative to the own elongation axis of the male conductor, against said stopper;

- more particularly, the stop includes a circumferential rib which extends along a peripheral contour of the cylindrical surface of the male conductor. The circumferential rib extends radially outwards from the hollow cylindrical surface, and relative to the proper elongation axis of the male conductor. According to a first embodiment, the stop extends along a closed circular profile all around the cylindrical surface. According to a second embodiment, the stop includes one or more radial segments distributed along a circular profile of the cylindrical bearing, each radial angular segment being spaced from another adjacent angular segment;

- according to a first alternative embodiment, the groove is of the type of a circumferential groove which extends around the proper elongation axis of the hollow cylindrical surface. More particularly, the groove is formed on the exterior wall of the hollow cylindrical surface. The groove thus forms a cavity from the exterior wall of the hollow cylindrical surface which extends around a peripheral contour of said hollow cylindrical surface and in the direction of the own axis of elongation;

– according to a first embodiment of the first variant, the circumferential groove extends along an angular segment on the exterior wall of the hollow cylindrical surface. Alternatively, according to a second embodiment of the first variant, the circumferential groove extends along a closed circular contour. This advantageous configuration makes it possible to make the groove visible from any angle of view of the male conductor in accordance with the first aspect of the invention;

- along a radial direction of the hollow cylindrical surface, perpendicular to the axis of proper elongation, the groove has a depth of between 0.1 mm and 3 mm;

- according to a second alternative embodiment, the groove is of the type of a flat formed on the exterior wall of the hollow cylindrical surface;

- in any of the alternative embodiments, at least part of the groove is of a different color from the exterior wall of the hollow cylindrical surface. This advantageous configuration makes it easier to identify the groove when assembling the female conductor to the male conductor;

- along the own elongation axis, a withdrawal position of the groove taken with respect to the stop stop is between 0 mm and 20 mm, preferably between 5 mm and 15 mm, still preferably between 8 mm and 12 mm in order to allow efficient and stable fitting of the female conductor. The withdrawal position thus forms the distance between the groove and the stop, taken along the own elongation axis. In particular, in the case where the fluid intended to circulate in the male conductor is of the gas type, then the withdrawal position is between 0 mm and 20 mm, preferably between 5 mm and 15 mm, more preferably between 8 mm and 12 mm in order to allow efficient and stable fitting of the female conductor. On the other hand, in the case where the fluid intended to circulate in the male conductor is of the type of a liquid, then the withdrawal position is between 0 mm and 5 mm, preferably between 2 and 5 mm, still preferably between 2 and 4 mm;

- along the axis of proper elongation, a recoil position of the groove taken relative to the axial end of the hollow cylindrical surface is between 4 mm and 20 mm, preferably between 5 mm and 15 mm, preferably still between 8 mm and 12 mm in order to allow efficient and stable fitting of the female conductor. The recoil position thus forms the distance between the groove and the axial end, taken along the axis of proper elongation. In particular, in the case where the fluid intended to circulate in the male conductor is of the gas type, then the recoil position is between 6 mm and 20 mm, preferably between 7 mm and 15 mm, still preferably between 8 mm and 12 mm in order to allow efficient and stable fitting of the female conductor. On the other hand, in the case where the fluid intended to circulate in the male conductor is of the type of a liquid, then the recoil position is between 4 mm and 20 mm, preferably between 5 mm and 15 mm, still preferably between 8 mm and 12 mm in order to allow efficient and stable fitting of the female conductor;

- an external diameter of the male conductor, taken at its external wall, is between 2.5 mm and 25 mm;

- the male conductor is made of a material containing plastic or metal. The plastic is preferably of the polyamide or polypropylene type. The rubber is preferably of the type of an elastomer.

According to a second aspect of the invention, a system of fluidic conduits is proposed comprising a male conductor conforming to the first aspect of the invention or according to any of its improvements, and a female conductor fitted onto the male conductor, a axial termination of the female conductor being located between the groove and the stop of the male conductor.

The fluidic conduit system conforming to the second aspect of the invention advantageously comprises at least one of the improvements below, the technical characteristics forming these improvements being able to be taken alone or in combination:

- an internal diameter of the female conductor is between 2.5 mm and 25 mm;

- an internal diameter of the female conductor is equal to or significantly greater than the external diameter of the male conductor. By significantly greater, we understand that the internal diameter of the female conductor is equal to the external diameter of the male conductor increased by a few tenths of a millimeter. This advantageous configuration makes it possible to force-fit the male conductor into the female conductor, so as to establish a more stable and more robust connection, while allowing fluid circulation between the male conductor and the female conductor without loss, i.e. that is to say without leaking. Alternatively, the internal diameter of the female conductor is less than the external diameter of the male conductor in order to obtain better sealing resulting from compression of the male conductor by the female conductor;

- the female conductor is made of a material containing plastic or rubber. The plastic is preferably of the polyamide or polypropylene type. The rubber is preferably of the type of an elastomer;

- the fluidic conduit system includes an O-ring housed in the groove of the male conductor. This advantageous configuration makes it possible to better identify the groove when assembling the female conductor to the male conductor. In particular, a color of the O-ring is chosen as different from that of the male conductor and/or the female conductor in order to facilitate the visualization of the O-ring on the male conductor and to facilitate the correct installation of the female conductor;

- an external diameter of the O-ring, when housed in the groove of the male conductor, is less than the diameter of the external wall of the hollow cylindrical bearing. This advantageous configuration prevents the O-ring from preventing the female conductor from engaging the male conductor;

- the fluidic conduit system includes a clamp clamping the female conductor on the male conductor. Advantageously, the clamp is located between the axial end of the male conductor and the stop stop. Preferably, the clamp is located between the axial end and the groove of the male conductor. Alternatively, the clamp is located between the groove and the stop of the male conductor.

According to a third aspect of the invention, there is proposed a method of assembling a system of fluidic conduits conforming to the second aspect of the invention or according to any of its improvements, the assembly method comprising the steps following:

- a step of introducing the male conductor, at its axial end, into the female conductor, taken at its axial end;

- a step of fitting the male conductor into the female conductor, along the proper extension axis, until the axial end of the female conductor is located between the groove and the stop of the conductor male.

The assembly process advantageously includes a step of clamping the fluidic conduit system using a clamp engaged on the female conductor and placed between the axial end and the stop of the male conductor.

During the clamping step, the clamp is advantageously placed between the axial end of the male conductor and the stop. Preferably, the clamp is placed between the axial end and the groove of the male conductor. Alternatively, the clamp is placed between the groove and the stop of the male conductor.

Various embodiments of the invention are planned, integrating according to all of their possible combinations the different optional characteristics exposed here.

It will be possible in particular to imagine variants of the invention comprising only a selection of characteristics described subsequently in isolation from the other characteristics described, if this selection of characteristics is sufficient to confer a technical advantage or to differentiate the invention from to the prior art.

In particular, all the variants and all the embodiments described can be combined with each other if nothing opposes this combination on a technical level.

In the figures, elements common to several figures retain the same reference.

With reference to FIGURES 1 to 4, the invention addresses a male conductor 11 of a fluidic conduit system 1 comprising the male conductor 11 and a female conductor 2 with which the male conductor 11 is intended to be coupled.

The male conductor 11 comprises:

- a hollow cylindrical surface 110 extending along a proper elongation axis O1, the cylindrical surface being delimited, radially with respect to the proper elongation axis O1, by an exterior wall 111 and an interior wall 112 The interior wall 112 thus defines a conduit for the circulation of a fluid in the male conductor 11;

- a stop 13 configured to achieve an axial stop of the female conductor 2, when the female conductor 2 is fitted onto the male conductor 11;

- a groove 14 located between an axial end 12 of the hollow cylindrical surface 110 and the stop 13 marking a minimal fitting.

Thus, the stop 13 and the groove 14 each form a mark on the male conductor 11 in order to allow optimal coupling of the female conductor 2 on the male conductor 11, as shown in the figure. . More particularly, the stop 13 and the groove 14 each form a mark on the male conductor 11 in order to respectively avoid pushing the female conductor 2 too far onto the male conductor 11, as illustrated in the , or not pushing the female conductor 2 enough onto the male conductor 11, as illustrated in the .

As visible in FIGURES 1 to 4, the stop 13 forms an end stop of engagement for the female conductor 2 on the male conductor 11, relative to the own elongation axis O1. The stop stop 13 thus makes it possible to establish a maximum axial limit for the fitting of the female conductor 2 onto the male conductor 11, relative to the own elongation axis O1. The stop 13 thus makes it possible to determine a maximum axial position of the female conductor 2 coupled to the male conductor 11 and for which the coupling is compliant and operational, that is to say for which the fluid circulation through the conductor male 11 and the female conductor 2 is produced without loss, as visible on the .

The stop 13 forms an axial shoulder 133 for the female conductor 2 with which the male conductor 11 is intended to be coupled. For this purpose, in the exemplary embodiment illustrated in FIGURES 1 to 4, the stop 13 comprises a circumferential rib 132 which extends along a peripheral contour of the cylindrical surface of the male conductor 11. circumferential rib 132 forming the stop 13 is delimited, relative to the own elongation axis O1, by a rear face 131 and by an axial shoulder 133 located on a proximal side of the rib 132. The rib 132 s extends radially outwards from the hollow cylindrical surface 110, and relative to the own elongation axis O1 of the male conductor 11.

Advantageously, a height of the rib 132, taken perpendicular to the own elongation axis O1 and from the outer wall 111, is greater than or equal to a thickness of the female conductor 2 taken between an exterior face 22 and an interior face 21 of said female conductor 2, in order to authorize an axial stop of the female conductor 2 abutting on the stop stop 13. Alternatively, the height of the rib 132, taken perpendicular to the own elongation axis O1 and from the wall exterior 111, is less than the thickness of the female conductor 2 taken between an exterior face 22 and an interior face 21 of said female conductor 2.

The groove 14 extends circumferentially around the own elongation axis O1 of the hollow cylindrical surface 110, from the outer wall 111 of the male conductor 11. More particularly, the groove 14 is formed on the outer wall 111 of the hollow cylindrical surface 110, thus forming a cavity from the exterior wall 111 of the hollow cylindrical surface 110 which extends around a peripheral contour of said hollow cylindrical surface 110 and in the direction of the interior wall 112.

The groove 14 is thus delimited by a bottom wall 142 which extends substantially parallel to the interior wall 112 of the hollow cylindrical surface 110, the bottom wall 142 being delimited, relative to the own elongation axis O1 , by a rear wall 141 located on the side of the stop 13 and a front wall 143 located on the side of the axial end 12 of the cylindrical bearing. In the exemplary embodiment illustrated in FIGURES 1 to 4, the groove 14 has a U shape in a transverse plane as shown in said FIGURES. Alternatively, the groove 14 can take a V-shaped profile.

Advantageously, the groove 14 extends circumferentially around the exterior wall of the hollow cylindrical surface 110 along a closed circular contour.

As mentioned previously, the relative positions:

– of the groove 14 relative to the axial end 12 of the male conductor 11,

– of the groove 14 relative to the stop 13,

– of the stop 13 relative to the axial end 12 of the male conductor 11,

Are not trivial and are of crucial importance for the good holding of the female conductor 2 on the male conductor 11.

Thus, along the own elongation axis O1, a withdrawal position X1 of the groove 14 taken relative to the stop 13 is between 0 mm and 20 mm. In particular, in the case where the fluid intended to circulate in the male conductor 11 is of the gas type, then the withdrawal position X1 is between 0 mm and 20 mm. On the other hand, in the case where the fluid intended to circulate in the male conductor 11 is of the liquid type, then the withdrawal position X1 is between 0 mm and 5 mm.

Analogously, along the own elongation axis O1, a recoil position X2 of the groove 14 taken relative to the axial end 12 of the hollow cylindrical surface is between 4 mm and 20 mm. In particular, in the case where the fluid intended to circulate in the male conductor 11 is of the gas type, then the recoil position X2 is between 6 mm and 20 mm. On the other hand, in the case where the fluid intended to circulate in the male conductor 11 is of the liquid type, then the recoil position X2 is between 4 mm and 20 mm.

Finally, in order to facilitate the engagement of the female conductor 2 on the male conductor 11, the male conductor 11 has an entry chamfer 15 formed on the axial end 12 of the hollow cylindrical surface 110. The chamfer 15 is formed on the outer wall 111 of the hollow cylindrical surface 110, the chamfer 15 forming a clearance angle with said outer wall 111. The chamfer 15 thus comprises a conical surface 153 at the level of the axial end 12 which faces the axial termination 23 of the female conductor 2 when it is approached to the male conductor 11 to be coupled there.

This particular shape of the chamfer 15 leads to having a rim 152 which extends circumferentially around the axis of proper elongation O1. The rim 152 extends at a distance from the outer wall 111 of the hollow cylindrical surface 110, thus forming a retaining face 151 which extends radially relative to the own elongation axis O1. The retaining face 151 thus forms a face of radial elongation facing the groove 14 and which prevents the female conductor 2 engaged on the male conductor 11 from retracting or becoming detached in an uncontrolled manner. In other words, the rim 152 of the male conductor 11 forms an anti-tearing member for the female conductor 2.

As mentioned previously, the illustrates optimal engagement of the female conductor 2 on the male conductor 11: in such an optimal coupling, the axial termination 23 of the female conductor 2 coupled to the male conductor 11 is located between the groove 14 and the stop 13. This configuration guarantees an optimal coupling for which the risks of untimely tearing and/or tearing of the female conductor 2 are minimal, or even non-existent.

There illustrates an undesired coupling of the female conductor 2 on the male conductor 11, in which the female conductor 2 would be too engaged, relative to the own elongation axis O1, so that the axial termination 23 of the female conductor 2 is located at -beyond the stop stop 13, relative to the groove 14. In other words, the stop stop 13 is then in an intermediate position between the groove 14 on the one hand and the axial termination 23 of the female conductor 2 on the other hand, relative to the own elongation axis O1. In such an undesired configuration, a risk of tearing of the female conductor 2 would be to be feared. This configuration is ultimately made impossible or even difficult to achieve due to the presence of the stop 13 which will form an axial stop for the axial termination 23 of the female conductor 2, as described previously.

There illustrates an undesired coupling of the female conductor 2 on the male conductor 11, in which the female conductor 2 would not be sufficiently engaged, relative to the own elongation axis O1, so that the axial termination 23 of the female conductor 2 is located in front of the groove 14, relative to the stop stop 13. In other words, the groove 14 is then in an intermediate position between the axial termination 23 of the female conductor 2 on the one hand, and the stop d stop 13 on the other hand, relative to the own elongation axis O1. In such an undesired configuration, a risk of accidental tearing of the female conductor 2 would be to be feared. The presence of the groove 14 thus makes it possible to verify that the female conductor 2 will be sufficiently fitted onto the male conductor 11 in order to achieve a functional and durable coupling.

There illustrates a block diagram of an assembly method 3 of the fluidic conduit system 1 object of the invention. Assembly process 3 comprises the following steps:

- a step 31 of introducing the male conductor 11, at its axial end 12, into the female conductor 2, taken at its axial end 23;

- a step 32 of fitting the male conductor 11 into the female conductor 2, along the proper extension axis, until the axial end 12 of the female conductor 2 is located between the groove 14 and the stop 13 of the male conductor 11.

The assembly method 3 advantageously comprises a step of clamping 33 of the fluidic conduit system 1 using a clamp engaged on the female conductor 2 and placed between the axial end 12 and the stop 13 of the male conductor 11. During the clamping step 33, the clamp is then advantageously placed between the axial end 12 of the male conductor 11 and the stop 13. Preferably, the clamp is placed between the axial end 12 and the groove 14 of the male conductor 11. Alternatively, the clamp is placed between the groove 14 and the stop 13 of the male conductor 11.

In summary, the invention relates to a male conductor 11 of a fluidic conduit system 1 comprising the male conductor 11 and a female conductor 2 with which the male conductor 11 is intended to be coupled, the male conductor 11 comprising a hollow cylindrical surface 110 extending along a clean elongation axis O1 and a set of marks making it possible to achieve optimal coupling of the female conductor 2 on the male conductor 11, the set of marks comprising a stop 13 configured to produce an axial stop of the female conductor 2 and a groove 14 located between an axial end 12 of the hollow cylindrical surface 110 and the stop 13 marking a minimum fitting.

Of course, the invention is not limited to the examples which have just been described and numerous adjustments can be made to these examples without departing from the scope of the invention. In particular, the different characteristics, shapes, variants and embodiments of the invention can be associated with each other in various combinations to the extent that they are not incompatible or exclusive of each other. In particular, all the variants and embodiments described above can be combined with each other.
