    [0001] The invention relates to the field of electric vehicle charging stations. The present invention applies in particular, but not exclusively, to tramway type vehicles.
    [0002] More specifically, the present invention relates first of all to an extensible electrical coupling device formed of a jack / coupler intended to be associated with an electric vehicle charging station to allow charging of an associated electric vehicle.
    [0003] Already known in the state of the art various devices for ensuring contact with an electric vehicle to recharge the vehicle at a charging station. EP 1938438 describes for example an electric vehicle charging station comprising an arm arranged on the roof of a bus / tramway and intended to come to connect in a socket equipping a station. Devices of the type described in the aforementioned document, however, do not give complete satisfaction. It is found in practice that the force generated during the deployment of the arm described in this document generates strong constraints and high risks of breakage. Since the energy used to actuate the jack described in the aforementioned document is pneumatic, it induces complex speeds and efforts to be managed, a pressure that is constantly maintained, which can be dangerous, for example, for example if a hand interferes. between the arm in deployment and the cone facing in reception of the arm.
    [0004] In addition, the aforementioned devices lead to unsightly protuberances on the roof of the bus, as well as a very bulky and heavy system that must be taken into account for the road behavior of the bus.
    [0005] The purpose of the invention is to propose means for improving the state of the art. This object is achieved according to the present invention by means of an electrical coupling device for a recharging station of an electric vehicle comprising a jack / coupler comprising an extensible arm adapted to be moved between a retracted position and an extended position in which the arm is adapted to provide an electrical connection, and support means of the jack / coupler allowing two degrees of freedom in rotation of the jack relative to a base support around two axes generally transverse to each other and generally orthogonal to a direction of extension of the arm , the jack / coupler being placed in a protective housing capable of angular movement about a vertical axis and about a horizontal axis perpendicular to the direction of extension of the arm relative to a support base. Those skilled in the art will understand that the invention thus proposes a jack system associated with the charging station and intended to cooperate with the vehicle coming to stand in front of a charging station. The cylinder has several degrees of freedom which optimizes the connection between the station and the vehicle. The cylinder also includes a reliable and secure moving system to optimize operation and prevent malfunction. According to other advantageous features of the invention: the extensible arm is at least in part (or comprises at least one part) flexible, the jack / coupler is placed in a housing, or casing, comprising a hatch solicited in closing position in the retracted position of the extensible arm and opening automatically when controlling the extension of the arm, - the device comprises a counterweight automatically moved in the opposite direction of the deployment of the extensible arm, in order to maintain the center of gravity of the assembly substantially at the point of intersection of the two pivot axes of the support means, the device comprises stop means limiting angular deflections around the pivot axes and damping means slowing the movement around the pivot axes.
    [0006] The present invention also relates to charging stations equipped with an electrical coupling device according to the invention of the aforementioned type. Other technical characteristics, aims and advantages of the present invention will appear on reading the detailed description which follows, and with reference to the appended drawings, given by way of non-limiting examples, and in which: FIG. a schematic perspective view of an electrical coupling device according to the invention in the retracted position of the extensible arm, the upper, lower and side housing elements of the casing not being shown to show the internal structure of the device, - the FIG. 2 represents another similar perspective view of the device according to the invention in the retracted position of the arm in a different orientation of the observation of FIG. 1, with other not shown casing elements; FIG. similar to FIG. 1 in the extended position of the arm; FIG. 4 is a partial view of the device illustrating in particular fully the hinge assembly of an intermediate member on a support base and the housing of the coupling device on the intermediate member, - Figure 5 shows another enlarged view of the same hinge means of the housing on the body intermediate and intermediate member on the base, - Figure 6 shows a view of the intermediate member hinged to the base, - Figure 7 shows a similar sectional view of the intermediate member articulated on the base to illustrate more particularly the production of a central axis in the form of a hollow cylinder for the passage of electric connection cable (s); - FIG. 8 is a diagrammatic view in longitudinal partial section of an anti-stop device; FIG. 9 is a partial view of the coupling device illustrating in particular a belt / pulley system for deployment of the arm, FIG. 10 is a view of a hatch. FIG. closing the housing in the closed position, - Figure 11 shows a similar view of the hatch being opened, - Figure 12 shows more precisely the cooperation between an actuating finger provided on a counterweight and a cam integral with the FIG. 13 schematically represents the cooperation between an electric charging station and a tram; FIG. 14 schematically represents the engagement of an extensible arm of the device of the electrical coupling according to the invention provided on a charging station; with a complementary cone provided on a tramway, - Figure 15 shows a similar view in the case of axial misalignment of the arm relative to the cone, - Figure 16 shows the automatic alignment of the arm on the cone resulting degrees of freedom of the extensible arm relative to the support base, according to the invention.
    [0007] The coupling device according to the present invention comprises: - a base 100 intended to be fixed on the support frame of a charging station, - an intermediate member 200 capable of angular displacement about a vertical axis 202 on the base 100, and a housing or housing 300 which houses a jack 310 whose arm 320 is expandable in a horizontal direction 322, orthogonal preferably to the direction of movement of the vehicle to be connected relative to the station.
    [0008] The housing 300 is itself capable of angular displacement about a horizontal axis 302 orthogonal to the extension direction 322. The base plate 100 may be subject to numerous variants and will not be described in FIG. detail thereafter.
    [0009] The intermediate member 200 has the general shape of a yoke, or U-shaped element, comprising a horizontal base 210 and two vertical wings or side walls 212, 214.
    [0010] The base 210 is articulated in rotation on the base 100 by any suitable means, for example by means of a crossed roller bearing 110 to allow a central orifice 120 to be left free, as illustrated in FIGS. 6 and 7, for the passage of cables from the station to the housing 300.
    [0011] The authorized angular displacement between the intermediate member 200 and the base 100 around the vertical axis 202 is limited by a system of spring stops 130 and dampers 140. It is thus preferably provided two pairs of stops 130 and of dampers 140 at the rate of one pair on each side of the base 210 and a stop 130 and a damper 140 on each side of the axis of rotation 202, as illustrated in Figures 6 and 7.
    [0012] The above-mentioned spring stop systems 130 are interposed between the flanks of the base 210 and facing planes 102 carried by a horizontal portion of the base 100. The spring-loaded stop systems 130 may be subject to numerous variants. of realization. It may be elements in accordance with the arrangements illustrated in FIG. 8, comprising, in a cage 132, a spring 134 which urges outwardly a stud 136 of elastomer, or the like, slidably mounted in the cage 132. means in the form of recesses 135, or equivalent, limit the outward biasing of the stud 136 relative to the cage 132 under the effect of the spring 134. The damping means 140, for example of the hydraulic type, are associated with the stops 130 for the compliance along the vertical axis 202 and prevent oscillations of the intermediate member 200 relative to the base 100. The housing 300 is itself rotated about the axis 302 on the wings 212, 214 of the yoke 200. Again, lateral plates 303, 304 25 connected to the sides of the housing 300 and hinged to the yoke 200 about the axis 302 are limited in angular displacement about this axis 302 by stops 230 and avg shock absorber 240 similar to means 130 and 140 above. As can be seen in FIG. 6, a pair of abutments 230 and dampers 240 are preferably provided on each side of each wing 212, 214 of the movable member 200 carried by the plates 303 and 304.
    [0013] The casing 300 has an elongated shape in the extension direction 322 of the arm 320. As illustrated more particularly in FIG. 3, the casing 300 here comprises four longitudinal walls 305, 306, 307 and 308 (not shown in the figure for reasons of clarity) and two end walls 309a, 309b. The front wall 309a, through which is intended to emerge the arm 320, is equipped with a flap or hatch 330, movable between a closed position, as shown in Figures 1 and 2, and an open position, as shown in FIG. 3. This provision will be specified later. The jack 310 is slidably mounted in the casing 300 in the extension direction 322. For this purpose, the jack 310 is for example mounted on a carriage 370 which is slidably guided in the extension direction 322 by rollers 312 mounted on rails 314 extending longitudinally parallel to the extension direction 322. As illustrated more particularly in FIG. 2, upper rollers 312a and lower rollers 312b respectively roll on the rail 314. The jack 310 is thus driven by a system gear motor 340 provided in the rear portion of the housing 300.
    [0014] The casing 300 also houses a continuous belt 360 wound on a first pulley 362 and a second pulley 364 respectively formed near the front walls 309a and rear 309b of the casing 300. The first and second pulleys 362 and 364 are each mounted in rotation around an axis generally orthogonal to the extension direction 322 of the jack 310 and to the horizontal axis 302. In the example illustrated in FIG. 9, the first pulley 362 is follower, while the second pulley 364 is driving. and is therefore rotated by the geared motor system 340.
    [0015] The jack 310 is fixed on a first strand 366 of the belt 360 and a counterweight 350 is provided on the second strand 368 of the belt 360, opposite to the first strand 366. Thus, when the jack 310 is moved forward in a extension position, the counterweight 350 is moved in the opposite direction, that is to say towards the rear of the housing 300, so that the center of gravity of the assembly formed by the cylinder 310 and the counterweight 350 remains always substantially in the vicinity of the point of intersection of the hinge pins 202 and 302, to balance the mechanical mass of the system regardless of the position of the cylinder 310. At the compared examination of Figures 1 and 3, it can be seen that retracted position of the arm 320, the counterweight 350 is located in front of the housing 300 in the vicinity of the hatch 330, as shown in Figure 1, while in the extended position of the arm 320, as shown in Figure 3, the counterweight 350 is located at the rear of the housing 300 near the rear wall 309b. The principle of the invention is thus to propose, as illustrated in FIG. 13, a tram station ST equipped on its upper part, in D, with the aforementioned electrical coupling device, object of the invention. The associated vehicles V, for example of the tramway type, are equipped on their roof with a complementary part of the end of the arm 320, for example a complementary female part in the form of a cone C adapted to receive the end of the arm 320. FIG. 14 thus illustrates an end of arm 320 being deployed in a position aligned coaxially with the inlet of cone C. In the case of such an alignment, the contact between the end of arm 320 and complementary means provided at the bottom of cone C can be established without difficulty.
    [0016] FIG. 15 illustrates the case of a misalignment between the end of the arm 320 and the cone C depending on the position of the vehicle V with respect to the station ST thus equipped.
    [0017] As can be seen in FIG. 16, thanks to the double angular clearance allowed of the coupling device according to the invention around the vertical axis 202 and the horizontal axis 302, combined if necessary with the intrinsic flexibility of the arm 320, end of the arm 320 can realign itself automatically on the bottom of the cone C, since the end of the arm 320 is located opposite the opening of the cone C. Such intrinsic flexibility, in combination with the double angular deflection, particularly allows the arm to form a single curvature and avoid curvature type "S" (with 2 curvatures), which could cause problems of malfunction or earlier deterioration. By way of non-limiting example in the context of the invention, the system may be adapted to accept a tolerance of plus or minus 100 millimeters at X, that is to say in the longitudinal direction of movement of the vehicle, and in Z, that is to say in the vertical direction, and a tolerance of plus or minus 250 millimeters in Y, that is to say in the direction of extension 322 of the arm 320 relative to the station.
    [0018] Still as a non-limiting example, the total stroke of the arm 320 in the extension direction 322 may be of the order of 1100 millimeters.
    [0019] The hatch 330 provided on the front wall 309a of the casing 300 has previously been mentioned. In the context of the invention, the flap 330 is preferably elastically biased in the open position (rest position) and mechanically held in the closed position. by a finger provided on the counterweight 350 (elastic stress position).
    [0020] Thus, preferably, the hatch 330 is articulated on the casing 300 around a vertical spring hinge 332. Upon removal of the jack / coupler 310, that is to say during the retraction of the arm 320 to the inside the casing 300, a finger 352 provided on the counterweight 350 abuts against a roller or a cam 324 integral with the hatch 330. The finger 352 thus forces the hatch 330 to close and tends the springs 334 integrated into the hinge 332. It is recalled that, in the rest position, the aforementioned springs 334 urge the hatch 330 to the open position. The aforementioned system thus makes it possible to link the opening of the flap 330 to the outlet of the arm 320 of the jack 310 to avoid any problem of operation, in particular leakage or sealing problem.
    [0021] FIG. 10 thus illustrates the hatch 330 in the closed position, the finger 352 of the counterweight 350 biasing the cam 324. FIG. 11 illustrates the hatch 330 in the intermediate opening position, the finger 352 of the counterweight 350 starting to move away from the cam 324, which releases the constraint springs 334 hinge of the flap 330 and engages the opening of the flap 330 simultaneously to the output of the arm 320. Figure 12 illustrates the flap 330 in fully open position. The springs 334 arranged at the axis of rotation 332 of the flap 330 are then in their unstressed rest position. It can be seen in FIG. 12 that the finger 352 of the counterweight 350 is no longer in contact with the cam 324 of the hatch 330.
    [0022] Those skilled in the art will appreciate that the invention offers the following advantages over the state of the art: - a robust, reliable, inexpensive and easy to install on a station, - a single actuator is necessary to ensure the connection, including the closure of the flap 330, - the half-ball system, namely the two degrees of freedom allowed for the casing 300 enclosing the arm 320 of the jack 310, makes it possible not to constrain the connection used to achieve the electrical connection between the charging station and the vehicle - the system according to the invention allows not to push too hard and avoids a large curve of movement of the connectors.
    [0023] Of course, the present invention is not limited to the particular embodiments which have just been described. FIG. 2 is a diagrammatic representation in FIG. 2 of an articulated connection means running from the opening 120 provided in the base 100 and connected to the arm 320 in order to ensure an adequate electrical connection, whatever the position at the time of the movements. angular of the casing 300 and in extension of the arm 320.
