Description

Technical Field

[0001] The present invention relates to a mechanism for a vehicle, the mechanism comprising a support device configured to support at least one component to be assembled in a front structure of the vehicle. The present invention also relates to a support device intended for such a mechanism. The present invention further relates to a vehicle equipped with a mechanism and / or a support device according to the present invention. The present invention finally relates to a method for installing a mechanism according to the present invention. Background Art

[0002] In the automotive industry, the evolution of vehicles from a conventional powertrain with an internal combustion engine to an electric or hybrid powertrain is accompanied by a significant increase in the mass of the vehicle due to the presence of a propulsion battery or a traction battery. Thus, a body shell structure designed for a vehicle with a combustion engine cannot be used in the same way for the production of a vehicle with a hybrid or electric powertrain without compromising the safety features provided by the vehicle. Specifically, the greater the mass of the vehicle, the greater the amount of energy to be absorbed in the event of a frontal collision, and the frontal collision may result in an increase in the forces encountered.

[0003] In the case of a vehicle with a combustion engine powertrain, it is known practice to reinforce the front structure of the vehicle by means of reinforcement elements such as tie rods, which are screwed to brackets and the body shell structure in order to counteract the lack of stiffness of the front structure. However, in the case of an electric or hybrid vehicle, such a mechanism is not sufficient to prevent deformation of the front structure of the vehicle, on the one hand because of their increased mass and on the other hand because they are not suitable for protecting high-voltage electrical systems.

[0004] In addition, the transition to an electric or hybrid powertrain is accompanied by the need to redesign the front structure of the vehicle in order to integrate additional components and also to ensure the protection of the various systems and interfaces present, such as hydraulic systems (relating to the thermal management of the propulsion battery and / or the passenger compartment) and electrical systems (including high-voltage power supplies for powering the propulsion battery).

[0005] It is known practice to equip the front structure of a vehicle with support elements configured to support the various components equipped on the front face. Such support elements are conventionally mounted on the brackets and / or the body shell structure of the vehicle, for example by attachment to reinforcement elements and / or tie rods. However, such a mechanism is accompanied by an increase in the number of different parts involved and, by extension, an increase in the spread of the various dimensions and the total tolerance of the combinations. In addition, interventions on the vehicle (for example in the context of replacing or repairing components or systems located on the front face) may prove to be complex and time-consuming, since they may require the removal of systems and components that do not require a specific intervention but hinder access to the target component or system. Summary of the Invention

[0006] The present invention falls within this context and aims to propose a mechanism that enables the front structure of a vehicle to be stabilized in the event of a frontal collision. The present invention also aims to propose a mechanism that allows better access to the various components and systems equipped on the front structure of the vehicle.

[0012] In particular, the body, the transverse member, and the tie rods can form a one-piece assembly.

[0013] The mechanism can further include at least one fin for additionally attaching the body to the body shell structure.

[0014] The mechanism can further include a heating unit, particularly a heating unit of the PTC type, which heating unit can be mounted on the body by means of at least one attachment device (such as a clip and / or a screw).

[0015] The mechanism can further include a battery protection cover, and the support device includes a plurality of fixing points for the cover.

[0016] The mechanism can include at least one fluid circulation pipe for a fluid, particularly a liquid such as water or a cooling fluid, and the support device includes at least one fixing area for attaching the at least one pipe.

[0017] The mechanism can include at least one power supply cable, particularly for powering a traction battery and / or an auxiliary battery, and the support device includes at least one fixing area for attaching the cable.

[0018] The present invention also relates to a support device for a vehicle, the support device being configured to support at least one component to be assembled in a front structure of the vehicle, the support device comprising:

[0019] - A planar body configured to support at least one component;

[0020] - A pair of tie rods configured to be attached to a bracket and a body shell structure;

[0021] - A transverse member connected to the body and connecting the tie rods to each other.

[0025] - A plurality of fixing points for attaching a battery protection cover;

[0026] - At least one fixing area for attaching at least one fluid circulation pipe;

[0027] - At least one fixing area for attaching at least one power supply cable, in particular for powering a battery.

[0028] The present invention also relates to a motor vehicle, in particular a vehicle having an electric powertrain, the motor vehicle comprising the mechanism and / or support device as described above.

[0029] Finally, the present invention relates to a method of installing the mechanism according to the present invention in a vehicle, the method comprising: attaching the support device from below to the bracket and the body shell structure via a plurality of fixing points including at least those in the tie rods so as to extend in contact with the lower surface of the bracket and the lower surface of the body shell structure, such that the support device is at least partially interposed between: on the one hand, the bracket and the body shell structure to which the bracket is respectively attached; and on the other hand, the ground on which the vehicle is resting.

[0030] Further details, features and advantages will become more apparent by reading the following detailed description given by way of non-limiting indication of a plurality of different exemplary embodiments shown in the following drawings:

[0031] Figure 1 is a simplified schematic depiction of the mechanism including the support device according to the invention, seen from below.

[0032] Figure 2 is a schematic depiction of a part of the mechanism, seen from above.

[0033] Figure 3 is a schematic perspective view of a part of the mechanism. DETAILED DESCRIPTION

[0034] Figure 1 Schematically shows an exemplary embodiment of the mechanism 1 according to the invention, arranged in the front structure of a vehicle 2, in particular a motor vehicle 2. The vehicle 2 under consideration is in particular a motor vehicle 2 having an electric powertrain. Alternatively, the mechanism 1 according to the invention can be applied, with the necessary modifications, to a vehicle 2 having a combustion engine powertrain including a combustion engine, or to a vehicle 2 having a hybrid powertrain including a combustion engine and at least one traction battery (also called a traction battery). The vehicle 2 can be, for example, a private vehicle or a multi-purpose vehicle.

[0035] Figures 1 to 3 Shows an exemplary embodiment of the mechanism 1 according to the invention. By convention, in the following description, the direction in which the motor vehicle 2 moves in a straight line is defined as the longitudinal direction X. The direction perpendicular to the longitudinal direction and lying in a plane parallel to the ground is called the transverse direction Y. The direction perpendicular to the directions X and Y is called the vertical direction Z. Thus, a Figure 1 conventional reference system XYZ used in the automotive field as shown is defined. The terms "top" and "bottom" or "upper" and "lower" should be understood in their general sense, where the terms "bottom" and "lower" refer to closer to the ground. Moreover, the terms "first" and "second" are intended to distinguish similar elements and not to define a hierarchy of said elements.

[0036] Generally, the mechanism 1 according to the invention includes a bracket 3, a body shell structure 4, and a support device 5 configured to support at least one component 6 to be assembled in the front structure of the vehicle 2.

[0037] The term "body shell structure" should be understood to particularly refer to conventional elements of the body shell structure 4, such as chassis-frame side rails, cross members, or side sill beams conventionally assembled to the vehicle 2.

[0038] Generally, the support device 5 includes at least a body 7, a pair of tie rods 8, and a transverse member 9. In particular, the term "tie rod" should be understood to mean a strengthening and / or connecting element. It should be understood that throughout the following description, any feature described with respect to the support device 5 included in the mechanism 1 according to the present invention can also be extended to the support device 5 itself for use in the mechanism 1 and / or the vehicle 2 according to the present invention.

[0039] The body 7 is planar and configured to support at least one component 6 assembled in the front structure of the vehicle 2. In particular, as shown, the component 6 under consideration may be a heating unit, in particular a heating unit of the PTC type, that is, having a positive temperature coefficient. Such a heating unit may be particularly intended for the thermal management of the passenger compartment of the vehicle 2. In addition, the component 6 may be included in the mechanism 1 according to the present invention.

[0040] In order to be able to attach the component 6 in question, the body 7 includes at least one attachment device 71. Preferably, the body 7 includes a plurality of said attachment devices 71. For example, the body 7 may include attachment devices 71 of the clip and / or screw type.

[0041] In the particular example shown, the body 7 has a generally rectangular shape, with the proximal side connected to the transverse member 9 and configured to have a maximum proximity to the bracket 3 within the mechanism 1 along the longitudinal direction. The rectangular shape further includes a distal side opposite the proximal side along the longitudinal direction, and two lateral sides connecting the proximal side and the distal side to each other.

[0042] The pair of tie rods 8 are configured to be attached to the bracket 3 at one end and to the body shell structure 4 at the other end. The tie rods 8 are connected to the body 7 by means of the transverse member 9. In addition, the tie rods 8 are connected to each other by means of this same transverse member 9 in order to ensure the stiffness of the support device 5 in the transverse direction Y when the mechanism 1 is assembled in the vehicle 2. It should be understood that throughout the following description, any description made with reference to one of the tie rods 8 can be extended to all of the tie rods 8 in the pair.

[0043] The tie rod 8 has the shape of an elongate, in particular at least partly straight, component which has two ends. The tie rod 8 is in particular connected at a first end 81 to the transverse member 9, while the opposite second end 82 extends towards the rear of the vehicle 2. In this particular case, the second end 82 of the tie rod 8 is a free end which is configured to be attached to the body shell structure 4, for example to a front transverse member (not shown) of the body shell structure 4, in particular a front transverse member of the floor. In particular, the transverse member 9 is configured to extend transversely or substantially transversely within the vehicle 2, that is to say parallel to the transverse direction Y. The tie rod 8 extends transversely to the transverse member 9, that is to say along a straight line which is secant to the direction of extension of said transverse member 9. Preferably, the tie rod 8 extends towards the rear of the vehicle 2 in a direction different from the longitudinal direction X, such that the tie rod forms a non-rectangular angle relative to the transverse member 9, in particular towards the outside of the vehicle 2 in the transverse direction Y.

[0044] The tie rod 8 also preferably has the shape of a profiled member. In particular, the tie rod 8 has a curved and / or inclined and / or stepped structure in the vertical direction Z. In this particular case, the position of the first end 81 is thus lower than the position of the second end 82 in the vertical sense.

[0045] Also preferably, the tie rod 8 has a limited height so as not to affect the ground clearance of the vehicle 2. Here, the "height" is to be understood as meaning the dimension measured in the vertical direction between the position of the first end 81 and the projection of the projection of the second end 82.

[0046] The tie rods 8 are arranged on both sides of the body 7 in the transverse direction Y such that they define a channel in which the body 7 extends.

[0047] In particular, the support device 5 is configured to be attached to the bracket 3 and the body shell structure 4 by means of a plurality of fixing points which at least include those in the tie rod 8. Thus, each tie rod 8 includes an orifice which is capable of receiving an attachment member 83 which is used to attach the tie rod 8 in question and further to attach the support device 5 to the bracket 3 or the body shell structure 4. For example, the attachment member 83 can be a screw or a screw / nut assembly.

[0048] Preferably, each tie rod 8 includes at least two different fixing points. In particular, in the example explained above, the first end 81 of the tie rod 8 is attached to the bracket 3 and the body shell structure 4 which are stacked on top of each other, while the second end 82 is attached to the body shell structure 4 so as to distribute the fixing points along the tie rod 8.

[0049] The mechanism 1 according to the invention, in particular the support device 5, is advantageously configured such that the support device 5 is attached to the bracket 3 and the body shell structure 4 from below. The expression "from below" means that the support device 5 extends in contact with the lower surface 301 of the bracket 3 and the lower surface 401 of the body shell structure 4, said lower surfaces 301, 401 being configured to face the ground inside the vehicle 2. In other words, when the support device 5 is mounted in the vehicle 2, at its fixing point, the support device is interposed between: the bracket 3 and the body shell structure 4 on the one hand; and the ground on which the mechanism 1 and / or the vehicle 2 are arranged in the vertical direction Z on the other hand. Therefore, the support device 5 has a lower positioning than the bracket 3 and the part of the body shell structure 4 on which it is mounted. As further explained below with reference to the mounting method according to the invention, the support device 5 can thus be assembled from below to the bracket 3 and the body shell structure 4 by the intervention of a technician from below the vehicle 2. Therefore, the fixing point is accessible from below the vehicle 2, thereby facilitating the mounting and dismounting of any element or component attached to the support device 5.

[0050] As mentioned above, the cross member 9 extends in the transverse direction Y in order to connect the pair of tie rods 8 to each other. As a result, the cross member 9 indirectly connects parts and / or elements of the body shell structure 4 that are opposite to each other in the transverse direction Y. The cross member 9 and the tie rods 8 are therefore used in particular to reinforce the bracket 3, in particular in the event that the vehicle 2 is involved in a frontal collision. In the vehicle 2, the cross member 9 is arranged to be interposed between the bracket 3 and the body 7 of the support device 5 in the longitudinal direction X.

[0051] In this sense, optionally but preferably, the cross member 9 and the tie rod 8 of the pair of tie rods 8 form a one-piece assembly. The expression "one-piece" means that the cross member 9 and the tie rod 8 cannot be separated from each other without causing damage or even destruction to these parts. In a specific and preferred manner, the body 7, the cross member 9, and the tie rod 8 form a one-piece assembly. Therefore, such a support device 5 advantageously makes it possible to strengthen the parts, reduce the tolerance sum of the combination, and reduce the number of different individual components, and thus simplify the assembly of the support device 5 in the vehicle 2.

[0052] In particular, all or part of the supporting device 5 may be made of sheet metal, aluminium and / or steel and may, for example, be pressed, welded and / or bent.

[0053] Optionally, the support device 5 may further comprise at least one fin 72 for additionally attaching the body 7 to the vehicle body shell structure 4. In this particular case, the support device 5 comprises a pair of fins 72. In particular, the fins 72 extend parallel or substantially parallel to the cross member, in the transverse direction Y, towards the outside of the vehicle. At least one fin 72 also extends at a non-zero distance from the second end 82 of the adjacent tie rod 8.

[0054] In particular, at least one fin 72 has a stepped structure such that its free end extends in a plane different from the plane in which the body 7 is located. For example, the free end of at least one fin 72 and the second end 81 of at least one tie rod 8 may be located in the same plane.

[0055] Moreover, in the case of a vehicle 2 having a hybrid powertrain or an electric powertrain (that is, a vehicle including at least one traction battery), it is known practice to provide a space within the front structure of the vehicle 2 for a shroud intended to protect the battery. A "shroud" herein refers to a shaped wrapper that at least partially surrounds or covers the battery in order to protect the battery. The support device 5 may also optionally but preferably be configured to include at least one fixing point 10 for attaching such a shroud, in particular a plurality of fixing points for attaching the said shroud. In the example shown, the support device 5 includes four fixing points 10 for attaching the protective cover. Thus, the mechanism 1 according to the invention may advantageously include a shroud (not shown) for protecting the battery, in particular a traction or propulsion battery, which is directly mounted on the support device 5.

[0056] The fixing points 10 for attaching the protective cover are particularly included in the transverse member 9 and / or in the pair of tie rods 8. In this particular case, the transverse member 9 includes two fixing points 10 for attaching the protective cover. In particular, the said fixing points 10 are distributed along the transverse member 9 so as to extend on both sides of the body 7 in the transverse direction Y. Moreover, the pair of tie rods 8 may include and / or carry a plurality of fixing points 10 for attaching the protective cover. In the example shown, each tie rod 8 carries a lateral extension 84 which includes one of the fixing points 10 for attaching the protective cover. The lateral extension 84 is particularly carried by the second end 82 of each tie rod 8 and is configured to extend towards the outside of the vehicle when the mechanism 1 is assembled in the vehicle 2. Preferably, each lateral extension 84 and the tie rod 8 form a one-piece assembly.

[0057] Optionally but preferably, the support device 5 may advantageously include at least one fixing area for attaching at least one fluid circulation pipe 11. For example, such a circulation pipe 11 may be configured to allow a liquid (such as water or a cooling fluid) to circulate. In particular, such a circulation pipe 11 may be intended to supply heating, ventilation and air conditioning or HVAC facilities, or a system for the thermal management of at least one element of the electric powertrain. The mechanism 1 according to the invention may also include at least one fluid circulation pipe 11. In the example shown, a plurality of fluid circulation pipes 11 are connected to the support device 5 and / or the component 6, in this case to the heating unit.

[0058] For example, as shown for the first circulation pipe 11a and the second circulation pipe 11b, the outer periphery of the circulation pipe 11 under discussion may include fingers or pins configured to be inserted into the orifices 73 included in the support device 5. Alternatively or additionally, the circulation pipe 11 under discussion may be attached to the support device 5 by means of an attachment element 12, for example as shown, which attachment element includes a ring configured to at least partially surround said pipe 11 and a base capable of cooperating with the support device 5 (for example cooperating with the orifice 73 as described above). Optionally, the base may include an attachment mechanism, such as a clip.

[0059] In the example shown, at least one pipe 11 may be attached to at least one of the fins 72. In particular, the fins 72 of the support device 5 include at least one orifice 73 capable of receiving the fingers, pins and / or attachment element 12 as described above. Additionally or alternatively, at least one pipe 11 may be attached to the body 7 of the support device 5 by a direct or indirect connection. For example, as shown in the figure, the body 7 may carry a tongue 74 which includes at least one orifice 73 capable of receiving the fingers, pins and / or attachment element 12 as described above. Preferably, such a tongue 74 extends from the lateral side of the body 7. Also, such a tongue 74 may be arranged in the longitudinal direction X between at least one of the fins 72 and the transverse member 9. According to an example which is an alternative or complement to the foregoing example not shown, at least one pipe 11 may be attached to the support device 5 at the transverse member 9.

[0060] Optionally, but preferably, the support device 5 according to the invention may advantageously include at least one fixing area for attaching the power supply cable 13. For example, the power supply cable 13 involved may be a low voltage (for example 12V) power supply cable 13 supplying power to an auxiliary battery, and / or may be a high voltage (for example 400V) power supply cable 13 especially for supplying power to a traction battery. Thus, the mechanism 1 may also include at least one power supply cable 13. In the example shown, a plurality of power supply cables 13 are attached to the support device 5, the first cable 13a being a 12V power supply cable and the second cable 13b being a 400V power supply cable.

[0061] Similar to what has been explained above with reference to the fluid circulation pipe 11, the outer periphery of at least one of said cables 13 may be configured to cooperate with the holes 75 included in the support device 5. Alternatively or additionally, the cable under discussion may be attached by a retaining element 14 similar to the attachment element 12 described above. For example, the retaining element 14 may include a ring configured to at least partially surround the cable and a base capable of cooperating with the support device 5 (in particular by means of a clip).

[0062] In the example shown, the first cable 13a is attached at the transverse member 9. Alternatively or additionally, such a cable can be attached at at least one of the fins 72. Additionally or alternatively, as shown for the second cable 13b, at least one cable can be attached to the body 7 of the support device 5 by direct or indirect connection. For example, as shown in the figure, the body 7 can carry a tab 76 which is configured to allow attachment and retention of at least one cable, for example by means of a screw or a clip. The tab 76 extends particularly transversely to, in particular orthogonally to, the body 7. In particular, it extends at least partly vertically upwards. The tab 76 preferably projects from the distal side of the body 7 so as to be furthest from any contact in the event of a frontal collision. Similarly, the tab 76 can extend into contact with the component 6 and / or be configured to form an end stop for the component 6, for example in at least one direction, in particular in the longitudinal direction X, in the event of a frontal collision. This example of attachment advantageously limits the movement of the power cables within the front structure, thus limiting the risk of fretting corrosion.

[0063] Optionally, but preferably, the mechanism 1 can include connection elements 15 which are configured to hold together different fluid circulation pipes 11 and / or different power supply cables 13.

[0064] In addition to reinforcing the bracket 3 and supporting the component 6 (in this case the heating unit) of the front structure of the vehicle 2, the support device 5 can thus optionally allow, based on the various options described above:

[0065] - attachment of the battery cover; and / or

[0066] - attachment of at least one fluid circulation pipe 11; and / or

[0067] - attachment of at least one power supply cable 13.

[0068] Thus, the support device 5 and the mechanism 1 according to the invention advantageously allow simultaneous and simplified access to the various devices and systems equipped in the front structure of the vehicle 2, which in this particular case are selected from a heating unit, a hydraulic system, an electrical system, and a cover.

[0069] On the one hand by reducing the total tolerance of the combination and the spread of the individual dimensions (as described above), and on the other hand by allowing the support device 5 to be mounted in the vehicle 2 from below and attached to the vehicle, the support device 5 also allows simplification of the installation of the support device 5 and the above-mentioned devices and systems within the vehicle 2.

[0070] In this sense, the invention also relates to a method of installing the mechanism 1 according to the invention in a vehicle 2. Such a method generally comprises attaching a support device 5 to a bracket 3 and a body shell structure 4 from below by means of a plurality of fixing points. The fixing points particularly include at least in these tie rods 8, and the support device 5 is arranged in such a way that it extends in contact with the lower surfaces 301, 401 of the bracket 3 and the body shell structure 4. Thus, the support device 5, in particular at least this pair of tie rods 8, is at least partially interposed in the vertical direction Z between: on the one hand, the bracket 3 and the body shell structure 4 to which it is attached; and on the other hand, the ground.

[0071] In particular, the first end 81 of the tie rod 8 can be attached to the bracket 3 and the body shell structure 4 at a region of the bracket 3 vertically superposed on the body shell structure 4. In contrast, the second end 82 is attached to the body shell structure 4.

[0072] Optionally, the method can include attaching at least one additional attachment fin 72 to the body shell structure 4 after attaching the tie rods 8 of the support device 5 to the bracket 3 and the body shell structure 4.

[0073] Optionally, the method can include attaching a protective cover to the support device 5 by means of a plurality of fixing points and fixing areas before attaching the support device 5 to the bracket 3 and the body shell structure 4.

[0074] Also optionally, the method can include attaching at least one fluid circulation pipe 11 to the support device 5 before attaching the support device 5 to the bracket 3 and the body shell structure 4.

[0075] Optionally, the method can include attaching at least one power supply cable 13 to the support device 5 before attaching the support device 5 to the bracket 3 and the body shell structure 4.

[0076] These rules are applied in the reverse order to allow the disassembly of the mechanism according to the invention.

[0077] Thus, various components, devices, and systems attached to the support device 5 can be installed in the vehicle simultaneously by means of the support device 5, which forms a common platform. This also applies in the case of disassembly.

[0078] Accordingly, the present invention provides a mechanism and a support device that simultaneously provide reinforcement of the front structure of a vehicle and support at least one component mounted on the front face of the vehicle. The mechanism and support device according to the present invention further allow for simplified installation and handling by reducing the number of different individual parts involved in the front structure of the vehicle and by allowing attachment from below to the bracket and the body shell structure. Finally, the support device and mechanism according to the present invention advantageously allow for securing and easier access to the various devices and systems of the front structure of the vehicle by concentrating at least some of their attachments on the support device.

[0079] However, the present invention is not limited to the devices and embodiments described and shown herein, but also applies to any equivalent devices or embodiments and any technically feasible combinations of such devices, provided that they ultimately achieve the functions described and shown in this document.
