Description

- 2 - -a second tubular body of longitudinal axis X having a first open axial end forming a female coupling organ, in which the male coupling organ is fitted into the female coupling organ so that the first tubular body is aligned with the second tubular body along the longitudinal axis X, and at least one of the first and second tubular bodies includes a housing extending along the longitudinal axis X, this housing being configured to receive within it an insertion organ of the reinforcement in a mold used during the manufacture of the tank. Thus, the reinforcement is not made from a single piece but from several pieces assembled together like Lego® bricks, the pieces here being the first and second tubular bodies. In the case where the reinforcement is made of plastic, it is understood that with a limited number of molds—those necessary for manufacturing the first and second tubular bodies—an unlimited number of reinforcements can be manufactured with configurations as varied as the integration needs. Moreover, even with moldsDespite its small size, nothing prevents the manufacture of large-sized reinforcements. In this way, reinforcement manufacturing is less expensive, more flexible, and less limited by molding capabilities than in the previous method. Furthermore, thanks to the recess provided in at least one of the first and second tubular bodies, there is also a means of receiving a reinforcement insertion element in a mold used during tank manufacturing. In other words, there is no need to provide another recess elsewhere in the reinforcement to receive such an insertion element. The first axial end of the first tubular body may be open or closed, while the first axial end of the second tubular body must be open to allow passage of the male coupling organ. Similarly, the housing may be in the form of a blind hole or a through hole. In the case of a through hole, the through hole passes completely through at least one of the first and second tubular bodies from one axial end to the other. Preferably, the insertion organ is an insertion rod for the insertion ofThe reinforcement is molded inside a wall during the manufacturing of the tank by extrusion blow molding. The male and female coupling elements form a mechanical coupling device. Thus, the mechanical coupling device performs a mechanical coupling function for complementary parts of the reinforcement (the first and second tubular bodies). The term "tank" refers to a sealed container suitable for storing a liquid, particularly a fuel, under various and diverse operating and environmental conditions. More precisely, a tank comprises a wall enclosing a hollow body defining an internal volume intended to contain a liquid such as a fuel. Thus, the expression "housed in a tank" should be understood as housed inside the hollow body, within the internal volume of a tank. Preferably, the hollow body is made of plastic. In this case, it includes...A hollow plastic body is preferred due to its superior elasticity and ability to be formed into complex shapes. A hollow plastic body can be produced by any known transformation process. One known method is injection molding. Extrusion blow molding and otomolding are also known processes. The term "plastic material" refers both to the generally homogeneous material of a single-layer structure and to the heterogeneous material of a multi-layer structure. The hollow body advantageously comprises at least one thermoplastic polymer, that is, a polymer which, under the influence of heat, melts or softens sufficiently to allow shaping. The term "polymer" refers to both homopolymers and copolymers (binary or ternary in particular). Examples of such copolymers include, but are not limited to, randomly distributed copolymers and sequenced copolymers.Block copolymers and grafted copolymers. Any type of thermoplastic polymer or copolymer whose melting temperature is lower than its decomposition temperature is suitable. Thermoplastic polymers with a melting range extending over at least ten degrees Celsius (10°C) are particularly well suited. Examples of such materials include those exhibiting polydispersity of their molecular mass. In particular, polyolefins, thermoplastic polyester esters, polyketones, polyamides and their copolymers can be used. A mixture of polymers or copolymers can also be used, as well as a mixture of polymeric materials with inorganic, organic and / or natural fillers such as, for example, but not limited to, carbon, salts and other inorganic derivatives, natural or polymeric fibers. It is also possible to use multilayer structures made up of stacked and bonded layers comprising at least one of the aforementioned polymers or copolymers.A commonly used polymer is polyethylene. Excellent results have been obtained with high-density polyethylene (HDPE). A commonly used polyamide is polyamide 6 (PA6). A polyamide tank offers greater resistance to internal pressure than the same tank made of polyethylene. 5 10 15 20 25 30 35 BE2024 / 5911 - 4 - In one example, the hollow body comprises a multilayer structure including at least one layer of thermoplastic material and at least one additional layer which may advantageously be made of a liquid and / or gas barrier material. Preferably, when the tank is a fuel tank, the nature and thickness of the barrier layer are chosen so as to limit as much as possible the permeability of liquids and gases in contact with the paroid of the fuel tank. Preferably, this layer is based on a barrier material, i.e. a fuel-impermeable resin such as EVOH, for example (ethylene-vinyl acetate copolymer). (partially hydrolyzed). Alternatively, the hollow body may be subjected to a treatment ofsurface (fluoration or sulfonation) intended to make it impermeable to fuel. It is understood that each tubular body of the reinforcement has two axial ends opposite each other and that at least one of these axial ends forms a coupling organ nested within a complementary coupling organ of an adjacent tubular body. Thus, one can assemble as many tubular bodies as necessary to obtain the desired reinforcement. For example, one can assemble three tubular bodies: a first tubular body having a male coupling organ at one axial end, a second tubular body having a female coupling organ at one axial end and a male coupling organ at the other axial end, and a third tubular body having a female coupling organ at one axial end. By nesting the male coupling organ of the first tubular body into the female coupling organ of the By fitting the male coupling organ of the second tubular body into the female coupling organ of the third tubular body, we obtain aThe framework consists of three tubular bodies. According to other optional characteristics of the framework, taken alone or in combination: - at least one of the first and second tubular bodies is a hollow tubular body with longitudinal axis X, such that the hollow of said tubular body forms said housing. Indeed, being an inherent part of the hollow tubular body, the housing does not need to be designed separately from said tubular body. -The first and second tubular bodies together comprise the said housing, such that the first tubular body comprises a first part of said housing and the second tubular body comprises a second part of said housing. Thus, the housing passes through the mechanical coupling device and extends further along the longitudinal axis X, allowing an insertion member to penetrate more deeply into the reinforcement. By this arrangement, the retention of the reinforcement by the insertion member is more secure and its insertion into the parison is more stable. 5 10 15 20 25 30 35 BE2024 / 5911 - 5 --The first and second tubular bodies are hollow tubular bodies with a longitudinal axis X, and the first axial end of the first tubular body is open, such that the hollows of the first and second tubular bodies join together to form the said housing. Indeed, being an inherent part of the first and second hollow tubular bodies, the housing does not need to be designed separately from said tubular bodies. Moreover, because of this arrangement, the mechanical coupling device fulfills a receiving function for an insertion element. -The first axial end of the first tubular body presents, in cross-section, an external shape s1 and the first open axial end of the second tubular body presents, in cross-section, an internal shape s2. The internal shape s2 is substantially identical to the external shape s1. Thus, the male coupling organ is fitted with a minimum of radial play in the female coupling organ. It should be noted that the "cross-section" is taken in a plane perpendicular to the axislongitudinalX and that the radial clearance is measured in this plane. - The external shapes 1 and internal shapes 2 are substantially polygonal. Preferably, the external shapes 1 and internal shapes 2 are substantially rectangular, preferably square. Indeed, unlike circular shapes, polygonal shapes allow the rotation (around the longitudinal axis X) of the first tubular body to be blocked within the second tubular body; this allows for translational guidance of the male coupling organ within the female coupling organ. This allows for better orientation and guidance of the first tubular body within the second tubular body when the male coupling organ is inserted into the female coupling organ. -The first tubular body comprises a first stop disposed at a first axial distance 1 from the first axial end of the first tubular body, with a face of the first open axial end of the second tubular body bearing against the first stop. The axial distance is measured along the longitudinal axis X. The firststopestunestopedefincourse,ainsilescorpustubulaires sont assembleddemandemion-relation-une-raison-à-l'autre. -The first open axial end of the second tubular body includes a deformable portion in the direction of the longitudinal axis X, the face of the first open axial end of the second tubular body bearing against the first stop being supported by this deformable portion. Thus, the tubular bodies are able to approach each other by sliding one into the other when the tank in which the reinforcement is fixed experiences a contraction of material, also called "material shrinkage". Indeed, during the manufacture of the tank by extrusion blow molding, after the reinforcement has been fixed inside the wall by pressing the wall against the reinforcement or against a component fixed to the reinforcement, and after the tank has been formed, it is still hot. 5 10 15 20 25 30 35 BE2024 / 5911 - 6 - When the tank returns to ambient temperature (by forced or natural cooling),The material contracts, which generates mechanical stresses in the reinforcement. These mechanical stresses are transmitted to the deformable portion, which deforms in the direction of the longitudinal axis X. By this arrangement, the tubular bodies are elastically joined to one another, which allows the structural cohesion of the reinforcement to be maintained despite the contraction. Furthermore, when designing a plastic tank, since the contraction of the plastic material is determinable, the deformable portion is dimensionally designed so that it absorbs all the axial contraction and that, at the end of the axial contraction, the reinforcement – ​​and its possible components – is positioned in a predetermined position in the tank. In an example where the axial contraction is 5 mm and the reinforcement includes a deformable portion, the latter is designed to deform by 5 mm in the direction of the longitudinal axis X. - the first tubular body includes a second stop disposed at a second axial distance 112 from the first axial end of the first tubular body and the secondThe tubular body includes a notch that cooperates with the second stop to prevent the male coupling element from separating from the female coupling element. The assembly consisting of the notch and the second stop forms a locking system for the mechanical coupling device. This locking system maintains the structural integrity of the reinforcement throughout the tank's lifespan, particularly when the pressure inside the tank increases. Indeed, when the pressure inside the tank increases, the tank tends to expand, which exerts a tensile force on the elements fixed inside the tank, especially the reinforcement. Thus, without this locking system, the male coupling element could separate from the female coupling element and cause dislocation of the frame, which is undesirable. This locking system also facilitates the handling of the frame, for example during the manufacture of the tank, by maintaining mechanical cohesion of theTubular bodies between each other until the reinforcement is inserted into a mold, for example. - A first axial clearance is provided between the second stop and the bottom of the notch. Indeed, during the deformation of the deformable portion, the tubular bodies move closer to each other by sliding into one another. For this sliding to be complete, it is necessary to prevent the second stop from being blocked in the bottom of the notch before the end of the axial contraction; this is the role of the first axial clearance. In an example where the axial contraction is 5 mm, the first axial clearance is at least 5 mm. The first axial clearance is measured along the longitudinal axis X. It should be noted that the notch is deformed to allow the second stop to pass when the male coupling member is inserted into the female coupling member. The deformation of the notch is typically a gap of a few tenths of 5 10 15 20 25 30 35 BE2024 / 5911 - 7 - millimeters of the notch. The second stop is also called the "disengagement stop" or "disengagement stop" (less common).-the second axial distance l2 is strictly less than the first axial distance l1. This allows us to limit the distance between the first and second stops in order to obtain a compact mechanical coupling device. -The notch is extended, in a direction opposite to the first open axial end of the second tubular body, by a straight slot, and the second stop is extended, in the direction of the first axial end of the first tubular body, by a straight guiding rib cooperating with the straight slot so as to guide the male coupling organ into the female coupling organ during interlocking. This arrangement is particularly useful when the external shapes 1 and internal shapes 2 are not polygonal but circular. Furthermore, the deformation of the notch is facilitated by the presence of the slot, which reduces the force required to separate the notch. -A second axial clearance is provided between a free end of the straight guiding rib and a bottom of the straight slot. The second axial clearance is greater than or equal toFirst axial clearance. Indeed, during the deformation of the deformable portion, the tubular bodies move closer to each other by sliding inside one another. For this sliding to be complete, it is necessary to prevent the free end of the straight guide rib from being blocked at the bottom of the straight slot before the end of the axial contraction; this is the role of the second axial clearance. In an example where the axial contraction is 5 mm, the second axial clearance is at least 5 mm. The second axial clearance is measured along the longitudinal axis X. According to one embodiment of the invention, the straight window has a length measured along the longitudinal axis X and a width measured in a direction perpendicular to the longitudinal axis X. The width of the window is delimited by two parallel edges opposite each other, and the length of the window is delimited by a bottom radially connecting the two parallel edges. In this example, the bottom of the straight window is the bottom radially connecting the two parallel edges. Advantageously, the free end of the straight guide rib is arranged atproximity of the first axial end of the first tubular body. This allows, when the male coupling member is inserted into the female coupling member, a longer guidance of the male coupling member within the female coupling member. - the frame also includes an anti-sway device, this anti-sway device being carried by at least one of the first and second tubular bodies. Preferably, the anti-sway device is made in one piece with said at least one of the first and second tubular bodies. This allows an anti-sway function to be integrated into the frame without having to attach a specific component to the frame such as, for example, an anti-sway deflector. -The framework includes, in addition, means for supporting at least one tank component, these support means being carried by at least one of the first and second tubular bodies. This allows for the attachment of components such as conduits, ventilation lines, valves, internal reinforcement elements, anti-bafflesThe invention also relates to an assembly intended to be housed in a vehicle tank, comprising a frame equipped with means for supporting at least one tank component and at least one tank component fixed to said frame by means of the support means. This allows components to be brought inside a container without having to carry them individually. The invention also relates to a vehicle tank, in particular a plastic fuel tank for a motor vehicle, in which either the aforementioned assembly or the aforementioned frame is housed. The invention also relates to a vehicle, in particular a motor vehicle, in particular a hybrid vehicle, comprising the aforementioned tank. The invention also relates to a method for manufacturing the aforementioned frame, a method comprising the following steps: a) having a first tubular body with a longitudinal axis X having a first axial end forming a male coupling organ,b) have a second tubular body with longitudinal axis X having a first open axial end forming a female coupling organ, c) fit the male coupling organ into the female coupling organ, so that the first tubular body is aligned with the second tubular body along the longitudinal axis X, d) provide a housing extending along the longitudinal axis X in at least one of the first and second tubular bodies, this housing being configured to receive within it an insertion organ for the reinforcement in a mold used during the manufacture of the tank. The invention also relates to a method for manufacturing a tank by extrusion blow molding, comprising the aforementioned assembly, a method comprising the following steps: a) having a frame comprising means for supporting at least one tank component, these support means being carried by at least one of the first and second tubular bodies, b) having at least one tank component, 5 10 15 20 25 30 35 BE2024 / 5911 - 9 -c) fix said at least one tank component to the frame by means of support means to form the aforementioned assembly, d) insert an insertion device into the frame housing, e) open a blow mold and insert a parison into the open mold, f) insert said frame into the mold, inside the parison, by means of the insertion device, g) bring the blow mold to an intermediate closed position in order to fix said at least one tank component inside the parison by pressing the parison against said at least one tank component, h) remove the insertion device, i) bring the blow mold to a final closed position in order to preform a tank, j) introduce a pressurized gas into the blow mold in order to form the (k) open the blow mold and remove the tank thus formed. (g) Since the paraison is made of molten plastic, pressing the paraison against at least one tank component causes the welding ofcomponent to the paraison or, more precisely, the thermo-welding of the component to the paraison. By welding said at least one tank component to the paraison, the reinforcement does not need to be itself welded to the paraison to be fixed in the tank since it is attached to the welded component by the support means.

Figure 2 is an exploded view of the frame 1 shown in Figure 1. This frame 1 comprises a first tubular body 10 with longitudinal axis X and aThe first tubular body 10 has a first axial end 10 forming a male coupling organ 100, and the second tubular body 20 has a first open axial end 20 forming a female coupling organ 200.

At least one of the first 10 and second 20 tubular bodies includes a housing 2 extending along the longitudinal axis X. The housing 2 is configured to receive within it a fitting for inserting the reinforcement into a mold used during the manufacture of the tank. This device is called mechanical couplingthe association of the male 100 and female 200 coupling members. In the embodiment shown, the first 10 and second 20 tubular bodies together comprise said housing 2, such that the first tubular body 10 comprises a first part 2 of said housing 2 and the second tubular body 20includes a second part 2b of said housing 2. In the illustrated example, at least one of the first 10 and second 20 tubular bodies is a hollow tubular body with longitudinal axis X, such that the hollow 3 of said tubular body 10, 20 forms said housing 2. More precisely, in the embodiment represented, the first 10 and second 20 tubular bodies are hollow tubular bodies with longitudinal axis X and the first axial end 10a of the first tubular body 10 is open, such that the hollows 2a and 2b of the first 10 and second 20 tubular bodies join together to form said housing 2. In the illustrated example, the second tubular body 20 with longitudinal axis X has a second axial end 20b forming a male coupling organ 210, and the frame includes a third tubular body 30 with longitudinal axis X. The third tubular body 30 has a first open axial end 30a forming a female coupling organ 300. The male coupling organ 210 is fitted into the female coupling organ 300 so that the third tubular body 30 is also aligned with the second.tubular body 20 along the longitudinal axis X. At least one of the second 20 and third 30 tubular bodies includes the housing 2. 5 10 15 20 25 30 35 BE2024 / 5911 - 12 - More precisely, in the embodiment shown, the first 10, second 20 and third 30 tubular bodies together include said housing 2, such that the first tubular body 10 includes a first part 2ad of said housing 2, the second tubular body 20 includes a second part 2b of said housing 2 and the third tubular body 30 includes a third part 2c of said housing 2. In the illustrated example, at least one of the first 10, second 20, and third 30 tubular bodies is a hollow tubular body with a longitudinal axis X, such that the hollow 3 of said tubular body 10, 20, 30 forms said housing 2.

Furthermore, the frame 1 includes support means 6 for at least one tank component; these support means 6 are carried by at least one of the first 10 and second 20 tubular bodies. More precisely, in the embodiment shown, the support means 6 are carried by the first 10, second 20 and third 30 tubular bodies. As illustrated in Figure 3, the first axial end 10a of the first tubular body 10 has, in cross-section, an external shape 1, and the first open axial end 20a of the second tubular body 20 has, in cross-section, an internal shape 2. The internal shape 2 is substantially identical to the external shape 1. Thus, the male coupling element 100 is fitted with a minimum of radial clearance in the female coupling element 200. It should be noted that the "cross-section" is taken in a plane P (see Figure 1) perpendicular to the longitudinal axis X, and that the radial clearance is measured in this plane. In this example, the external shapes 1 andThe internal shapes 2 are substantially polygonal. More precisely, in the embodiment shown, the external shapes 1 and internal shapes 2 are substantially rectangular. As illustrated in Figure 4, the first tubular body 10 comprises two stops: a first stop 11 disposed at a first axial distance el1 from the first axial end 10a of the first tubular body 10 and a second stop 12 disposed at a second axial distance el2 from the first axial end 10a of the first tubular body 10. The second stop 12 is extended, in the direction of the first axial end 10a of the first tubular body 10, by a straight guiding rib 13. In this example, the second axial distance el2 is strictly less than the first axial distance el1. As illustrated in Figure 5, the first open axial end 20 of the second tubular body 20 comprises a deformable portion 22 in the direction of the longitudinal axis X.

In this example, the second tubular body 20 includes a notch 23 extended, in a direction opposite to the first open axial end 20a of the second tubular body 20, by a straight window 24. As illustrated in Figure 6, the face 21 of the first open axial end 20a of the second tubular body 20 rests against the first stop 11 and the notch 23 cooperates with the second stop 12 so as to prevent the male coupling organ 100 from separating from the female coupling organ 200. In this example, the straight guiding rib 13 cooperates with the straight window 24 so as to guide the organ male coupling 100 in the female coupling organ 200 during its insertion. In the embodiment shown, a first axial clearance 4a is provided between the second stop 12 and a bottom 15 of the notch 23 and a second axial clearance 4b is provided between a free end 14 of the straight guide rib 13 and a bottom 25 of the straight slot 24. The second axial clearance 4b is greater than or equal to the first axial clearance 4a.Figures 7 and 8 show a framework 1 comprising an anti-sloshing device 5. The anti-sloshing device 5 is carried by at least one of the first 10 and second 20 tubular bodies. In Figure 7, the first tubular body 10 carries the anti-sloshing device 5 and the second tubular body 20 carries support means 6, while in Figure 8, the first 10 and second 20 tubular bodies carry the anti-sloshing device 5. In the embodiment shown in Figure 7, the anti-sloshing device 5 is made in one piece with the first tubular body 10, and in the embodiment shown in Figure 8, the anti-sloshing device 5 is made in two parts: a first part made in one piece with the first tubular body 10 and a second part manufactured in one piece with the second tubular body 20. In the illustrated example, the anti-sway device 5 includes anti-sway deflectors. Weld surfaces (also called "weld pads" or "weld pads") in(English language) 5a, 5b, 5ce and 5d are provided at the top of the deflectors for welding the reinforcement 1 to the assembly. Figure 9 shows an assembly 7 intended to be housed in a vehicle tank, comprising a reinforcement 1 and at least one tank component 8. Said at least one tank component 8 is fixed to said reinforcement 1 by means of support means 6. Preferably, said at least one tank component 8 is an internal reinforcing element. An "internal reinforcing element" is a structural element assembled at its two longitudinal ends to the tank made of plastic material in order to limit the deformation of the tank when the pressure inside the tank increases. 5 10 15 20 25 30 35 BE2024 / 5911 - 14 - More precisely, the internal reinforcement element is intended to connect two opposite walls of the plastic tank (see figure 10). It is assembled, for example welded, at the weld surfaces located at its two longitudinal ends, to the joint which will give rise to the plastic tank.The frame 1 also includes deformable links 6 connecting the frame 1 to the support means 6. The deformable links 6 can deform to allow relative displacement of the frame 1 and the support means 6. Figure 10 shows a vehicle tank 110, in particular a plastic fuel tank for a motor vehicle, in which the assembly 7 is housed. Figure 11 shows a vehicle 120, in particular a motor vehicle, in particular a hybrid vehicle, comprising a tank 110. In one example, the manufacturing process of the frame 1 comprises the following steps: a) having a first tubular body 10 with longitudinal axis X having a first axial end 10 forming a male coupling organ 100, b) having a second tubular body 20 with longitudinal axis X having a first open axial end 20 forming a female coupling organ 200, c) fitting the male coupling organ 100 into the female coupling organ 200, so that the first tubular body 10 is aligned with the second tubular body 20 along the longitudinal axis X,d) provide a housing 2 extending along the longitudinal axis X in at least one of the first 10 and second 20 tubular bodies, this housing 2 being configured to receive within it an insertion device for the reinforcement in a mold used during the manufacture of the tank. In one example, the blow-molding process for manufacturing a tank 110 comprising a frame 1 having support means 6 for at least one tank component includes the following steps: a) having a frame 1 having support means 6 for at least one tank component, b) having at least one tank component 8, c) attaching said at least one tank component 8 to the frame 1 by means of the support means 6 to form the assembly 7 described above, d) introducing an insertion device 9 (see Figure 12) into the housing 2 of the frame 1, e) opening a blow-molding mold and extruding a section into the open mold, f) inserting said frame 1 into the mold, inside the section, by means of the insertion device 9. 15 20 25 30 35 BE2024 / 5911 - 15 -g) bring the blow mold into an intermediate closing position in order to fix said at least one tank component 8 inside the parison by pressing the parison against said at least one tank component 8, h) remove the insertion member 9, i) bring the blow mold into a final closing position in order to preform a tank 110, j) introduce a pressurized gas into the blow mold in order to form the tank 110 by blowing, k) open the blow mold and remove the tank 110 thus formed. In one example, it is provided that at least one component 8 of the tank is provided with weld surfaces; thus, in step g), pressing the assembly against at least one component 8 of the tank causes the weld surfaces of the component 8 to be welded to the assembly. In one example, the extrusion blow molding manufacturing process of a tank 110 comprising a frame 1 having an anti-sloshing device 5 carried by at least one of the first 10 and second 20 tubular bodies comprises the following steps:a) have a frame 1 comprising an anti-sloshing device 5 carried by at least one of the first 10 and second 20 tubular bodies, b) insert an insertion device 9 into the housing 2 of the frame 1, c) close a blow mold and insert a diaphragm into the open mold, d) insert said frame 1 into the mold, inside the diaphragm, by means of the insertion device 9, e) bring the blow mold into an intermediate closed position in order to fix the frame 1 inside the diaphragm by pressing the diaphragm against said frame 1, f) remove the insertion device 9, g) bring the blow mold into a final closed position in order to pre-form a reservoir 110, h) introduce a pressurized gas into the blow mold in order to form the reservoir110 by blow molding, i) open the extrusion-blow mold and remove the reservoir110 thus formed. In an example, it is provided that the said frame1 is provided with weld surfaces (see
