[0001] DESCRIPTION
[0002] TITLE OF THE INVENTION: ELECTRIC OR HYBRID MOTOR VEHICLE COMPRISING A CROSS BEAM INCLUDING AN INTEGRATED DUAL-CHARGE MODULE
[0003] The present invention claims priority from French application No. FR2500637 filed on January 22, 2025, the content of which (text, drawings and claims) is incorporated herein by reference.
[0004]
[0001] The invention relates to the arrangement of electronic components of electric or hybrid motor vehicles, in particular the arrangement of the integrated dual charging module.
[0005]
[0002] Prior art patent application DE102011113198 is known, describing a vehicle engine compartment comprising a crossmember for mounting an electric machine. The crossmember extends transversely across the vehicle and is supported by the vehicle body via bearings. The crossmember has a central portion containing a cavity for housing a power electronic device. The cavity is rectangular in shape along the transverse direction. However, a drawback remains. The crossmember has only one cavity in which to position the power electronic device. However, in the case of an electric or hybrid motor vehicle, there are essential components that must be positioned near this crossmember: the on-board charger, the DC / DC converter, and the inverter.If the crossmember consists of only one of these components, then it is necessary to arrange the other components around said crossmember, and thus reduce the available space in the engine compartment of said vehicle.
[0006]
[0003] The objective of the present invention is to overcome these drawbacks and to increase the available space around a crossmember of an electric or hybrid motor vehicle to facilitate the arrangement of the components of said vehicle.
[0004] To achieve this objective, the invention proposes an electric or hybrid motor vehicle comprising a front axle and a rear axle whose points of contact with the ground define a base plane defined by a first longitudinal direction corresponding to straight-line driving, by a second transverse direction orthogonal to the first longitudinal direction, and a third vertical direction orthogonal to the first and second directions and oriented away from the ground, said vehicle comprising an integrated dual-charging module including an on-board charger and a DC / DC converter.the vehicle comprising a crossmember extending in the second direction, said crossmember comprising a housing, notable in that said integrated dual-charge module is positioned in said housing, the integrated dual-charge module comprising an upper cover in the third direction, said upper cover being fixed to said crossmember.
[0007]
[0005] Thanks to the invention, the crossmember allows for optimization of space within the vehicle, which facilitates the arrangement of other components. In addition, the integrated dual-load module directly contributes to the rigidity of said crossmember.
[0008]
[0006] Preferably, the crossmember includes an additional housing, said vehicle including an inverter, said inverter being positioned in said additional housing.
[0009]
[0007] This further increases the available space around said crossmember to facilitate the arrangement of the other vehicle components. In addition, the inverter also contributes to the rigidity of said crossmember.
[0010]
[0008] Preferably, the additional housing comprises four walls so that said inverter is entirely surrounded by said walls, the housing comprising two walls substantially parallel to each other along the second direction.
[0011]
[0009] Thus, the inverter is firmly held and protected by said crossmember. In addition, the integrated dual-load module is thus accessible from the front and rear, which facilitates its assembly or disassembly for maintenance operations, for example.
[0010] Preferably, said integrated dual-load module comprises at least a plurality of electrical connectors, each electrical connector being positioned on either side of said integrated dual-load module in the first direction.
[0012]
[0011] Thus, it is easy to electrically connect said integrated dual-charge module with other components because the electrical connectors are accessible on both sides of said cross member.
[0013]
[0012] Preferably, the upper cover is fixed to said crossbar by a plurality of screws.
[0014]
[0013] This is a simple and effective means of fixing to ensure that said integrated dual-charge module remains in said housing.
[0015]
[0014] Advantageously, said housing has a length between 300 and 350 mm along the first direction, preferably 330 mm.
[0016]
[0015] Advantageously, said housing has a width between 360 and 400 mm along the second direction, preferably 390 mm.
[0017]
[0016] Advantageously, said housing has a height between 120 and 160 mm along the third direction, preferably 140 mm.
[0018]
[0017] Such dimensions allow for easy arrangement of the integrated dual-load module in said crossmember within the vehicle.
[0019]
[0018] The invention will be further detailed by describing non-limiting embodiments, and based on the accompanying figures illustrating variants of the invention, in which:
[0020] - [Fig.1] schematically illustrates an empty crossmember of an electric or hybrid motor vehicle according to one embodiment of the invention;
[0021] - [Fig. 2] schematically illustrates, in a first view, the crossbeam shown in Figure 1, which includes an integrated dual-load mode
[0022] - [Fig.3] schematically illustrates the crossbar shown in figure 2 in an opposite view.
[0023]
[0019] Figure 1 schematically illustrates an empty crossmember 2 of an electric or hybrid vehicle 100 according to an embodiment of the invention. The vehicle 100 comprises a front axle and a rear axle whose points of contact with the ground define a base plane XY defined by a first longitudinal direction X corresponding to straight-line travel, a second transverse direction Y orthogonal to the first longitudinal direction X, and a third vertical direction Z orthogonal to the first direction X and the second direction Y and oriented away from the ground. The vehicle 100 comprises said crossmember 2, which is preferably a motor support crossmember. Indeed, the vehicle comprises an electric motor and, optionally, said electric motor is suspended below said crossmember 2 along the third direction Z. The crossmember 2 extends along the second direction Y.Furthermore, said vehicle 100 includes an integrated dual charging module 1 comprising an on-board charger and a DC / DC converter, more commonly known as a DC-DC converter (acronym for Direct Current / Direct Current). The crossmember 2 has a housing 3. The integrated dual charging module 1 is positioned in said housing 3. The integrated dual charging module 1, generally called an IDCM (acronym for Integrated Dual Charging Module), is an electronic component configured to manage the charging of the vehicle 100's battery using either alternating current or direct current. This optimizes the available space around said crossmember 2.In this way, the on-board charger and the DC / DC converter are combined into a single component, namely the integrated dual-charge module 1, which is suitable for housing in housing 3, thus avoiding the need to incorporate another housing in crossmember 2. The on-board charger is an electronic component designed to convert alternating current, for example supplied by a household electrical outlet or a charging station, into direct current to allow the charging of the vehicle's battery 100. The DC / DC converter is an electronic device whose role is to adapt the DC voltage from an electrical source so that said DC voltage meets the requirements of a given circuit or output device.Preferably, said housing 3 comprises two walls positioned opposite each other, said walls of housing 3 being substantially parallel to each other, along the second direction Y. Optionally, said integrated dual charging module 1 comprises a plurality of electrical connectors 6 positioned on either side of said integrated dual charging module 1 along the first direction X. When said housing 3 comprises only two walls, it is possible to electrically connect said electrical connectors to other components of the vehicle.
[0024]
[0020] By way of example, said housing 3 has a length along the first direction X of between 300 and 350 mm. Preferably, said length is 330 mm. Housing 3 also has a width along the second direction Y. The width is preferably between 360 mm and 400 mm. Even more preferably, said width is 390 mm. Finally, housing 3 has a height along the third direction Z. The height of the housing is, for example, between 120 mm and 160 mm. Preferably, said height is 140 mm. These dimensions are suitable for allowing the easy arrangement of the integrated dual-load module 1 in said crossmember 2 of a standard motor vehicle as known in the prior art.
[0025]
[0021] The integrated dual-load module 1 is shown in said cross member 2 in Figure 2. The integrated dual-load module 1 has an upper cover 4 along the third direction Z. The upper cover 4 is fixed, preferably by means of a plurality of screws 7, to said cross member 2.
[0026]
[0022] Optionally, the vehicle includes an inverter, and said crossmember 2 includes an additional housing 5. The inverter is an electronic component whose purpose is to convert the direct current stored in said battery into alternating current to power the vehicle's electrical machine. The inverter is positioned in said additional housing 5. This allows, in addition to optimizing the space allocated to said integrated dual-charge module 1, the optimization of the space of said inverter. Consequently, there is more space available around said crossmember 2, and the arrangement of the other components within the vehicle is facilitated. Furthermore, the integrated dual-charge module 1 and the inverter fully contribute to the rigidity of the crossmember 2. Preferably, said additional housing 5 has four walls so that, when said inverter is positioned in said additional housing 5, then said inverter is completely surrounded by walls.Thus, it is firmly held and protected in said crossbar 2.
