Description

[0001] Title: Support device for at least one pipe intended to equip a motor vehicle

[0002] The present invention relates to the field of mechanics and automobiles and more particularly concerns the assembly of components, and in particular supply pipes arranged between these components, within a motor vehicle engine compartment.

[0003] The assembly of a vehicle involves a docking step of a body, associated with the passenger compartment and on which are positioned different components of a motorization system or a thermal regulation system for example, and a mechanical plate, associated with the running gear and on which are positioned other components of these systems. Pipes extend between the components of the same system, for circulation of water, lubricant or refrigerant fluid for example, and this whether these components are mounted on the body or on the mechanical plate. These pipes are previously fixed on one or more components located on the mechanical plate, or on the body, and must be connected to another or more other components located on the body, or on the mechanical plate, once the body and the mechanical plate are fixed to each other at the end of the docking step.During the docking stage, when the mechanical plate is moved towards the body, the pipes, which at this time have a free end, should not become entangled, which could cause them to be damaged, and should not become sandwiched between a component of the body and a component of the mechanical plate, which would result in damage to the pipe and poor attachment of the mechanical plate to the body.

[0004] Furthermore, once the body and the mechanical plate are assembled, and the pipes connected at each of their ends, the pipes should be kept in a position that prevents them from rubbing against the transmission elements of the vehicle, to avoid heating and wear. In this context, support devices are provided that combine clips, or plastic tabs, present on the pipes and attachment means associated with the body or the mechanical plate, which are capable of cooperating with the clips. These attachment means may consist of screw-nut systems that lock the position of the clip by coming into an appropriate hole formed on the body or the mechanical plate. The positioning of these holes, and therefore of the pipe attachment points, is specific to each vehicle and to the positioning of the different components.Such a solution is therefore complicated to implement for different vehicles which share the same mechanical plate with different bodies, or vice versa, since the position of the components and the resulting path of the pipes can be modified from one vehicle to another.

[0005] In this context, the main subject of the present invention is a support device for at least one pipe, in particular a plurality of pipes, each being intended to equip a motor vehicle and to extend between a first component of the vehicle mounted on a body of the vehicle and a second component of the vehicle mounted on a mechanical plate of the vehicle capable of being assembled on said body, said support device comprising on the one hand a structural element and on the other hand an intermediate support, the structural element being configured to be fixed on the mechanical plate or on the body of the motor vehicle, the intermediate support being fixed to the structural element and comprising at least one receiving zone, in particular a plurality of receiving zones, of a hooking means configured to ensure the fixing of a pipe.

[0006] The support device according to the invention is intended to equip a motor vehicle and has the particularity of having an integral assembly formed by the association of a structural element and an intermediate support. This integral assembly makes it possible to associate a structural function, with the structural element, which can in particular make a mechanical link between the body and the mechanical plate, and the intermediate support which is designed to allow the attachment of one or more pipes respectively making it possible to circulate a particular type of fluid from a component arranged in a first sub-assembly of the vehicle, formed by the body, to another component arranged in a second sub-assembly of the vehicle, formed by the mechanical plate.

[0007] In the case of a plurality of pipes to be managed during the assembly of the mechanical patina on the body, the intermediate support allows the fixing of several pipes, which avoids having to provide a plurality of fixing zones arranged everywhere on the body or on the mechanical plate, and which facilitates the operations of fixing the pipes to the support device, since the operator only has one place to attach the pipes.

[0008] The present invention thus aims to propose a solution making it possible to have a compact support device for a motor vehicle, with a structural element that is as standard as possible, in other words applicable to the most models of motor vehicles, and capable of fixing an intermediate support that is modifiable to adapt to the conformation of the engine compartment, extending between the body and the mechanical plate, which is specific to the vehicle that it equips. Furthermore, the support device according to the invention is configured, in particular with the specific configuration of the intermediate support to be fixed on the structural element, to allow a pipe connection step that is simplified after the vehicle docking step.

[0009] In the following description, the vehicle body must be considered broadly as the structure of the vehicle linked to the passenger compartment and the components linked to it, and the mechanical plate must be considered broadly as the underbody of the vehicle and the mechanical components linked to it, such as, for example and without this being exhaustive, the engine, the electric traction battery, the running gear, the underbody forming the support structure for these components also being called the cradle.

[0010] According to an optional characteristic of the invention, the intermediate support comprises a first face pressed against a fixing wall of the structural element and a second face opposite the first face, the pipe being opposite this second face.

[0011] In other words, the intermediate support is interposed between the structural element and the pipe(s).

[0012] According to an optional characteristic of the invention, the structural element comprises at least one orifice for the passage of a means of fixing the intermediate support to the structural element, the fixing means projecting from the first face of the intermediate support.

[0013] Advantageously, the fixing means comprises a screw whose threaded rod extends projecting, and perpendicularly, from the first face of the intermediate support, and this threaded rod is configured for positioning and fixing the intermediate support on the structural element by cooperating with the orifice arranged in the structural element, namely a threaded orifice or a nut associated with a smooth-walled orifice.

[0014] Alternatively, the fixing means may be arranged on the structural element and protrude from the latter to cooperate with the orifice, and where appropriate the associated nut, which in this case are arranged in the intermediate support. However, it is recalled that the support device according to the invention is advantageous in that the intermediate support is adaptable and can take several configurations to apply to a particular type of vehicle while the structural element remains a standard part applied without modification of its structure on several vehicles.In this context, it is conceivable that the structural element is used without intermediate support on certain types of vehicle, in particular if the pipe attachments are made in another way, and it is preferable in this case that the structural element does not have a protruding element which could penalize the arrangement of the other components and that it has more of an orifice capable of cooperating with a fixing means carried by the intermediate support so as not to have a protruding element on the structural element hindering any element making up the engine compartment of a specific vehicle.

[0015] According to an optional characteristic of the invention, the structural element and the intermediate support comprise an anti-rotation system formed by a tab made on one of these two parts and by an opening formed in the other part, the tab being configured to fit into the opening.

[0016] According to a first alternative, the structural element comprises an opening for the passage of a tab of the anti-rotation system which projects from the intermediate support and which is intended to pass through said opening arranged in the structural element.

[0017] According to a second alternative, the intermediate support comprises an opening for the passage of a tab of the anti-rotation system which projects from the structural element and which is intended to pass through said opening arranged in the intermediate support.

[0018] As with the fixing means, for reasons of space requirement in the engine compartment, it is advantageous for the lug of the anti-rotation system to be arranged in said intermediate support so as not to leave a protruding lug penalizing the space requirement in the engine compartment if the retaining element is used alone on a vehicle, without an intermediate support and pipe attachment function.

[0019] According to an optional feature of the invention, the opening of the anti-rotation system is an oblong hole.

[0020] According to an optional feature of the invention, the intermediate support comprises at least one hole configured for the passage of a fixing head of a hooking means. The fixing head is designed to be able to be inserted into the hole by elastic deformation. Thus, the fixing head can be deformed when the entry of the hooking means associated with the pipe is forced, the fixing head having a dimension greater than that of the hole so that the elastic return participates in blocking the hooking means and therefore the pipe relative to the intermediate support. The operator in charge of storing the pipes when the mechanical plate is docked on the box can thus easily retrieve the pipes and clip them in the same area, namely on the same intermediate support.

[0021] According to an optional characteristic of the invention, at least one first hole is configured to receive a means for attaching a first pipe and at least one second hole is configured to receive a means for attaching a second pipe, the at least one first hole having a shape and / or an orientation different from that of the second hole.

[0022] According to an optional feature of the invention, the first hole and the second hole are adjacent and have an oblong shape, the first hole and the second hole being arranged so that their main axes of elongation are substantially perpendicular to each other.

[0023] These differences in the shape and / or orientation of the holes make it possible to form a means of error correction, which prevents a pipe from being hooked via its hooking means in a hole that is not dedicated to it. This makes it easier to connect the pipes when docking, by ensuring that the pipes fixed to the intermediate support are not forced into a position that was not intended.

[0024] According to an optional characteristic of the invention, the intermediate support is a part having several portions extending respectively in different planes, the parts of the anti-rotation system and of the fixing means formed on the intermediate support both being arranged on the same portion of the intermediate support.

[0025] In other words, the intermediate support comprises several portions which extend in intersecting planes, or in parallel but not coincident planes, and the tab of the anti-rotation system, where appropriate the opening, and the fixing means, where appropriate the orifice, are arranged in the same portion, that is to say in the same plane. According to an optional characteristic of the invention, the holes formed in the intermediate support are arranged so that a single hole is formed in the same portion of the intermediate support. In other words, each hole intended to receive a fastening means extends in a plane not coincident with the plane of another hole intended to receive another fastening means.

[0026] According to an optional characteristic of the invention, the intermediate support is a folded sheet, each fold aiming to position a portion in a different plane from the adjacent portion.

[0027] According to an optional characteristic of the invention, the structural element is made of mechanical welding.

[0028] The invention also relates to a motor vehicle comprising a plurality of components respectively fixed to a body of the vehicle or to a mechanical plate of the vehicle and comprising a plurality of pipes connecting these components together, said vehicle comprising at least one support device as previously mentioned and on which all or part of the pipe(s) is fixed.

[0029] According to an optional characteristic of the invention, the structural element is configured to be integral with the intermediate support and to connect the mechanical plate to the body of the vehicle.

[0030] The invention also relates to a method for mounting a support device as previously described on a motor vehicle comprising at least the following steps, including a step of fixing the intermediate support to the structural element, a step of connecting a first end of a pipe to a component arranged on the mechanical plate, respectively on the body, a step of fixing the pipe to the intermediate support via a hooking means, a step of docking the mechanical plate to the body of the vehicle with a fixing of the body and the mechanical plate via the structural element and a step of assembling a second end of the pipe to be connected to a component arranged on the body, respectively on the mechanical plate. These steps must be carried out one after the other to avoid intermingling or crushing of the pipe(s) at the time of the docking step associating the body and the plate of the vehicle.

[0031] Other characteristics, details and advantages of the invention will emerge more clearly on reading the description which follows on the one hand, and examples of embodiment given for informational and non-limiting purposes with reference to the appended drawings on the other hand, in which:

[0035] [Fig. 5] illustrates the intermediate support of Figure 4 with another viewing angle allowing the opposite face to be seen from that visible in Figure 4.

[0036] The features, variants and different embodiments of the invention may be combined with each other in various combinations, provided that they are not incompatible or mutually exclusive. In particular, variants of the invention may be conceived comprising only a selection of features described below in isolation from the other features described, if this selection of features is sufficient to confer a technical advantage and / or to differentiate the invention from the state of the prior art.

[0037] In the detailed description which follows, the terms "longitudinal", "vertical" and "transverse" refer to the orientation of the vehicle in which the elements of the invention are placed. A longitudinal direction corresponds to a direction in which the main axis of elongation of the vehicle and its main direction of advance are inscribed, this longitudinal direction being parallel to a longitudinal axis L of a reference frame L, V, T. A vertical direction corresponds to a direction perpendicular to the ground on which the vehicle equipped with the support device according to the invention rests and the corresponding vertical axis V is perpendicular to the longitudinal axis L. Finally, a transverse direction corresponds to a direction parallel to a transverse axis T of the reference frame L, V, T, this transverse axis T being perpendicular to the longitudinal axis L and to the vertical axis V.

[0038] As a reminder, the invention relates to a support device 1 for a plurality of pipes 2, in which an intermediate support 30 is configured to be fixed to a structural element 28 of a motor vehicle and to receive means for attaching the plurality of pipes 2.

[0039] Figure 1 illustrates a vehicle engine compartment equipped with the support device 1 according to the invention, and it illustrates more particularly an engine compartment delimited by a first subassembly commonly called body 8, or body structure, occupying an upper part 10 of the engine compartment and a second subassembly otherwise called mechanical plate 12 occupying a lower part 14 of the engine compartment. The body 8 here has a side member 9 which extends essentially longitudinally towards the front of the vehicle. The mechanical plate 12 extends mainly in a horizontal plane under the body 8 and it comprises in particular a cradle 17, here in two parts, on which are fixed various motorization elements, with here a motor 19, transmission, with here the transmission universal joints 26, or battery.

[0040] The body 8 and the mechanical plate 12 are connected to each other at least by means of a support device 1 according to the invention, which has a structural portion arranged substantially vertically. More precisely, the support device 1 comprises a first end 1a fixed for example by welding to the mechanical plate 12 and a second end 1b fixed to the body 8 by means of a sleeve 15 cooperating with a receiving barrel 16 formed in the side member 9 of the body 8. As visible in FIGS. 2 and 3, the sleeve 15 has a cylindrical shape intended to be inserted into the receiving barrel 16 whose shape corresponds to that of the sleeve 15.

[0041] As seen in Figure 1, the support device 1 is also configured to fix a plurality of pipes 2. In this Figure 1, two pipes are visible, with a pipe 2 of which we see a first end 18 linked to a first component 20 arranged on the mechanical plate 12 and a second end 22 connected to a second component 24 arranged on the body 8. These different components can just as easily be a water pump, a compressor, a heat exchanger, the battery or the thermal or electric engine of the vehicle, without this list being exhaustive.

[0042] As a result, the support device 1 is configured to fix the pipe 2 between the first end 18 and the second end 22. In particular, the support device 1 fixes the pipe 2 so as to avoid contact of this pipe 2 with transmission elements 26 present in a transmission zone shown in dotted lines in FIG. 1 located between the body 8 and the mechanical plate 12. Contact of the pipes 2 with the transmission elements 26 would cause rapid degradation of said pipes 2, consequently impacting their technical performance, in other words their capacity to transport the appropriate fluid from the first component 20 to the second component 24.

[0043] As will be described in more detail in the following paragraphs, the support device 1 according to the invention is composed of a structural element 28 and an intermediate support 30. In this way, each of the parts forming the support device 1 ensures one of the functions which have just been mentioned. More particularly, the structural element 28 ensures the mechanical hold between the body and the mechanical plate 12, and more particularly the suspension of the cradle 17, and the intermediate support 30 ensures the fixing of the pipes.

[0044] Figures 2 to 5 illustrate more particularly the support device 1 and the two parts which constitute it, with here a portion of the cradle 17 forming the mechanical plate 12.

[0045] The structural element 28 comprises a fixing wall 28a to which the intermediate support 30 is fixed. The intermediate support 30 has a first face 30a and a second face 30b opposite each other. The first face 30a of the intermediate support 30 is arranged opposite the fixing wall 28a of the structural element 28. Furthermore, the intermediate support 30 is arranged such that the second face 30b faces towards the interior of the vehicle and therefore towards the interior of the engine compartment and the components housed therein.

[0046] The structural element 28 is here a mechanically welded part formed of three parts particularly visible in FIG. 3 and among which said fixing wall 28a, a reinforcing wall substantially perpendicular to the fixing wall and the previously mentioned sleeve 15, each of these parts being welded to at least one other by weld beads 29.

[0047] The intermediate support 30 is fixed to the structural element 28 by a fixing means 32. In the example illustrated, the fixing means 32 consists of a screw, as visible in FIG. 5, which forms a projection of the intermediate support 30 on the side of the first face 30a. In FIG. 2, only the screw head, which projects on the side of the second face 30b, is visible. This screw is intended to engage in an orifice 34 formed in the structural element 28 as visible in FIG. 3, and a nut can be attached against the fixing wall 28a of the structural element, if necessary by being welded against the structural element.

[0048] Alternatively, it may be provided that the intermediate support is irreversibly fixed to the structural element, for example with a fixing means 32 which takes the form of a weld, or a rivet, the structural element being equipped accordingly with an orifice 34 or not.

[0049] On the other hand, the support device 1 comprises an anti-rotation system 36 associated with the fixing means 32, in particular when the fixing means is, as illustrated in the figures, produced via a screw and a nut. The anti-rotation system makes it possible to prevent the intermediate support from pivoting around the screw axis of the fixing means when the intermediate support 30 is fixed to the structural element 28. The anti-rotation system 36 consists of a tab 38, here formed in the material of the intermediate support 30 and folded to form a projection of the first face 30a of this intermediate support 30, intended to be inserted into an opening 39 of appropriate shape, here arranged in the structural element 28 as visible in FIG. 3.

[0050] The tab 38 here has a rectangular cross-section shape, which is housed in an oblong-shaped opening 39, so as to allow play when mounting the intermediate support 30 on the structural element 28.

[0051] The tab 38 of the anti-rotation system 36 prevents the rotation of the intermediate support around the main elongation axis of the fixing means 32. It is advantageous for this purpose that the tab 38 is arranged on the same portion 40 of the intermediate support 30 as that on which the fixing means is arranged, the different portions 40 of the intermediate support being discussed in more detail below.

[0052] It is understood that this allows a fixed position of the intermediate support 30 relative to the structural element 28 which prevents the potential movement of the pipes 2 when they are fixed to the support device 1.

[0053] Furthermore, the intermediate support 30 comprises several holes 42 of different shape and / or orientation from one hole to another, whether this shape is circular or oblong for example. These holes 42 are configured for the passage of a hooking means 44 intended to fix a pipe 2 on the intermediate support 30. The hooking means 44 consists of a clip whose body is arranged around a pipe 2 to be fixed on the intermediate support and whose fixing head is sized to be inserted into the holes 42 by elastic deformation. An example of a hooking means is illustrated in FIG. 2.

[0054] As mentioned, a single part, namely the intermediate support 30, makes it possible to position and fix the plurality of pipes 2 in the same area of ​​the engine compartment and the structural element 28 has the role of ensuring the mechanical holding of the body 8 and the mechanical plate 12 and of maintaining the intermediate support 30 within the engine compartment, between the body 8 and the mechanical plate 12. In this context, it is understood that the structural element 28 is configured to be as “standard” as possible, that is to say to be able to be integrated into as many vehicles as possible while the intermediate support 30 can be variable and modifiable, depending on the type of vehicle on which it will be integrated, by adding holes 42 at different positions for example. This configuration has the advantage of saving the number of parts necessary for fixing the pipes which usually requires a clip per pipe to be maintained.

[0055] Figures 4 and 5 illustrate the isolated intermediate support and in particular make visible the configuration in portions 40 arranged in several distinct planes and the distribution of several holes 42 in these portions of the intermediate support 30 to allow the positioning of the pipes 2 relative to each other, each hole 42 being capable of cooperating with a clip for fixing a pipe.

[0056] More particularly, the intermediate support 30 comprises several portions 40 which extend in distinct planes, that is to say intersecting planes or at least parallel and non-merged planes. As illustrated, among these portions, and in a context where the intermediate support 30 is a folded sheet metal, for example produced by stamping, the portions 40 may comprise a base portion 40a, a first folded portion 40b, a second folded portion 40c and a third folded portion 40d. The base portion 40a is intended to be pressed against the fixing wall of the structural element 28 and the folded portions extend on either side of this base portion 40a. The base portion 40a comprises the fixing means 32 and the tab 38 of the anti-rotation system 36, and each folded portion 40 is intended to receive at least one hole 42.

[0057] The folded portions all extend in planes that are distinct from the plane in which the main base portion extends, so that the fixing plane of the base portion and the planes in which the holes for attaching the pipes extend are distinguished. More particularly, the base portion 40a extends in a fixing plane that coincides with the plane of the fixing wall of the structural element 28 and the first folded portion 40b extends in a plane P1 substantially perpendicular to the fixing plane. The second folded portion 40c extends in a plane P2 substantially parallel to the fixing plane, in particular due to a double fold between the base portion 40a and the second folded portion 40c. The base portion 40a constitutes a central portion and connects each of the first, second and third folded portions.The third folded portion 40d extends opposite the first folded portion 40b relative to the base portion 40a and has several branches which are inclined relative to each other and which each have a hole 42.

[0058] This stepped configuration of the intermediate support 30 thus makes it possible to offset the attachment zones of the pipes relative to the retaining element. This facilitates the prepositioning of the pipes 2 before docking the body 8 and the mechanical plate 12.

[0059] The first folded portion 40b comprises a first hole 42a and a second hole 42b. These two holes extending in the same plane PI, they have different shapes and / or orientations, to form keying means making it possible to ensure that a pipe intended to be hooked in the first hole 42a is not hooked in the second hole 42b, which would have the effect of constraining the pipe and weakening it. Here, the shapes of the two holes are the same, namely an oblong hole, but the orientations are different, with the elongation axis of the first hole 42a being perpendicular to the main elongation axis of the second hole 42b.

[0060] This keying makes it possible to position several pipes 2 with distinct functions on the same support, here the intermediate support 30, without risking interchanging them. The intermediate support 30 is configured to facilitate the correct connection of different pipes 2 with each pipe which is positioned in the intended location, in particular at a time of docking of the mechanical plate 12 on the body 8 where it is necessary to quickly ensure that the pipes do not drag and do not risk being pinched between components.

[0061] This function is also ensured by the offset of the planes in which the other holes extend respectively. The second folded portion 40c comprises a third hole 42c which extends in a plane offset from the others and which is relatively far from the other holes so that its orientation is only conditioned by the direction that one wishes to give to the fixing clip which will be inserted into this third hole 42c. The third portion 40d comprises a first branch in which a fourth hole 42d and a fifth hole 42e extend successively, two adjacent holes substantially in the same plane which this time differ from each other in their shape, with the fourth hole which is oblong in shape and the fifth hole 42e which is circular in shape, and it also comprises a second branch which comprises a sixth hole 42f, which has a different orientation from the fourth hole 42d which can be considered adjacent.

[0062] Without this being limiting of the invention, the first hole 42a can be configured to receive a clip for fixing a pipe 2 transporting a fluid to an engine not shown in the figures, while the second hole 42b and the fifth hole 42e are configured to fix in several zones the same pipe 2 transporting water, and the third hole 42c is here configured to fix a pipe 2 transporting a heat transfer fluid to a heat exchanger.

[0063] Figures 4 and 5 also show a general shape of the intermediate support 30 comprising a curved edge 48 intended to go around the transmission zone.

[0064] We will now describe a method of assembling a motor vehicle during which a mechanical plate carrying different components is docked on a body of the vehicle, with an operation of connecting pipes between components carried by the plate and components carried by the body. The assembly method implements a support device as described, in particular to allow the pipes to be organized and stored so that they are not damaged during docking.

[0065] The support device 1 is initially mounted on the mechanical plate of the vehicle, with the structural element 28 which is welded onto the cradle 17 of this mechanical plate, and with the intermediate support 30 which is then fixed to the structural element 28 by means of the fixing means 32. The first end 18 of a pipe 2 is connected to a first component 20 mounted on the mechanical plate 12 and this pipe 2 is then fixed to the intermediate support 30, by inserting, here by elastic deformation, a hooking means 44 secured to the pipe in one of the holes 42. This operation is repeated for each of the pipes intended to extend between a component associated with the body and a component associated with the mechanical plate, each pipe being hooked to the intermediate support in one or more holes dedicated to it.Once all the pipes are attached, the box 8 and the mechanical plate 12 are then assembled during a docking operation, with the structural element 28 which is fixed on the box via the socket 15 inserted in the receiving barrel 16. The second end 22 of each of the pipes 2 can then be connected to a second component 24 arranged in the box 8. The operator can for this purpose easily recover the second end of each of the pipes since they are all connected at the same place.

[0066] As just described, the present invention achieves the aims it has set itself, namely to allow the fixing of several pipes in a common area, by providing a single support device for each of these pipes. The support device is also configured to allow this grouping of pipes to be organized so that they do not become tangled. The support device according to the invention thus allows a saving of mechanical parts and time when connecting the pipes after the step of docking the body and the mechanical plate, while also ensuring a function of mechanical holding of the mechanical plate relative to the body.

[0067] The present invention cannot, however, be limited to the means and configurations described and illustrated here and it also extends to any equivalent means and configuration as well as to any technically effective combination of such means.
