Description

[0001] Title of the invention: Connection system for a motor vehicle protecting at least one connection zone.

[0002] The present invention relates to the field of electric charging systems, and more particularly to such electric charging systems for electric or hybrid vehicles.

[0003] Electric or hybrid vehicles are vehicles capable of transporting passengers and / or goods. These vehicles include an electric motor capable of converting electrical energy stored in energy storage equipment, such as batteries, into mechanical energy capable of setting the vehicle in motion, for example by rotating the vehicle's wheels.

[0004] As the vehicle operates, the energy stored in the batteries diminishes, requiring them to be recharged by the user. Charging equipment, such as wall-mounted terminals, can be used to recharge the vehicle's batteries. This charging equipment may include a charging cable designed to connect to a vehicle's connection system for recharging the batteries.

[0005] According to various standards, such as NF C61-314, and to protect the user from the risk of electrocution, these connection systems include a sealing device at the connection areas intended to be connected with a connection terminal of the charging cable. This sealing device makes it possible, on the one hand, to protect the user from the risk of electrocution by preventing the user from contacting the connection elements of the connection areas and, on the other hand, to protect the connection elements from the risk of oxidation.

[0006] Existing solutions are not satisfactory because they require the user to first remove them and then connect the charging equipment to the vehicle's connection system. Such handling requires the user to hold the closure device with one hand and connect the charging equipment with the other. Such handling requires the user to have two hands free, which can be inconvenient for the user when the latter needs to recharge their electric or hybrid vehicle.

[0007] The present invention proposes to overcome at least this drawback of the prior art by means of a connection system intended to supply electrical energy to a motor vehicle, the connection system comprising a body which comprises a first connection zone and a second connection zone distinct from each other, at least one of said connection zones being configured to be electrically connected with at least one electrical terminal, the connection system comprising at least one flap configured to take at least one configuration in which the flap prohibits access to at least one of said connection zones, the connection system comprising a valve which controls the configuration of the flap,the valve being able to take a first position in which the flap is in a first configuration prohibiting a connection between the connection zone and the electrical terminal and a second position in which the flap is in a second configuration authorizing a connection between said connection zone and the electrical terminal.

[0008] The first connection area and the second connection area each comprise complementary connection pins of the electrical terminal. In other words, the connection system forms a female socket in which the electrical terminal, which is a male socket, is housed so as to allow an electrical connection between the connection system and a charging socket comprising said electrical terminal. It is understood that the electrical terminal is a connector of a charging socket intended to be electrically connected with a connection pin.

[0009] The flap is able to move between its first configuration and its second configuration so that depending on the configuration in which the flap is located. The electrical terminal can be introduced into said connection zone or the electrical terminal cannot be introduced into said connection zone by being blocked by the flap. The blocking of the insertion of the electrical terminal into one of said connection pins of the connection zone is done by coming into abutment against the flap which is then interposed between the electrical terminal and the connection zone.

[0010] It is understood that in the first configuration of the shutter, the insertion of the electrical terminal in the connection area is prohibited by the shutter.

[0011] According to a characteristic of the invention, the first connection zone is an alternating current supply zone and the second connection zone is a direct current supply zone. It is understood that the connection system is capable of electrically connecting to at least one type 2 connector and to a combined charging system, better known as a “combo socket”. According to a characteristic of the invention, in the first configuration of the flap, the flap is opposite the direct current supply zone. In this first configuration of the flap, the flap is opposite the second connection zone. In this configuration of the flap, the insertion of an electrical terminal into the second connection zone is prevented by the flap which is interposed between the electrical terminal and the second connection zone.

[0012] According to a characteristic of the invention, the flap is opposite the connection zone when said flap is in its first configuration and the flap is offset relative to said connection zone when said flap is in its second configuration. It is understood that "offset" means that the flap is not opposite the connection zone so that the electrical connection between the connection zone and the electrical terminal is possible. In other words, the flap moves so as to no longer clutter the space located in front of the connection zone.

[0013] More specifically, the flap is offset in an area distinct from the projection of the connection area, said projection being defined along the connection pins of the connection area. The flap is therefore offset from the projection of the connection pins along an axis along which at least one of said connection pins extends.

[0014] According to a characteristic of the invention, the shutter is configured to translate along a translation axis. The translation of the shutter allows it to move from its first configuration to its second configuration and vice versa. It is understood that the change in configuration of the shutter is not carried out by a rotation of the shutter around an axis of rotation. In other words, the shutter moves from its first configuration to its second configuration and from its second configuration to its first configuration while remaining in the same plane.

[0015] According to a characteristic of the invention, the valve is capable of driving the flap in translation along said translation axis. Actuation of the valve makes it possible to set the flap in motion so as to free the space located in front of a connection zone. The actuation of the valve is carried out by approaching the charging socket comprising at least one electrical terminal intended to electrically connect with the connection zone. By approaching the charging socket to the connection zone, the valve will be actuated and the flap will pass from its first configuration to its second configuration progressively with the actuation of the valve. According to a characteristic of the invention, the flap translates along at least one guide element carried by the body and which extends along a straight line intersecting a direction of elongation of a connection pin of the connection zone.This connection pin constitutes a connection area opposite the shutter when the shutter is in its first configuration.

[0016] According to a feature of the invention, the guide element extends partly through the flap. Such a feature allows the flap to translate along the guide element. It is understood that the flap is connected to the guide element and movable in translation relative to this guide element. It should be noted that it is understood that the flap is connected to the guide element in that the flap cannot be dissociated from the guide element.

[0017] According to a characteristic of the invention, the connection system comprises two guide elements arranged on either side of the first connection zone and the second connection zone. Such an arrangement of the guide elements makes it possible to eliminate degrees of freedom of the shutter, and in particular to prevent the rotation of the shutter around an axis of rotation or a point of rotation.

[0018] According to a characteristic of the invention, the valve is movable in rotation between its first position and its second position around an axis of rotation.

[0019] According to a characteristic of the invention, the axis of rotation of the valve is intersecting with the axis of translation of the shutter. This axis of rotation is perpendicular to the axis of translation of the shutter.

[0020] According to a characteristic of the invention, the valve extends opposite the flap when said valve is in its first position. It is understood that the arrangement of the valve opposite the flap means that the valve is also opposite a connection zone. When the user wishes to insert the charging socket into the connection system, a part of the charging socket naturally comes into contact with the valve. In addition, by continuing to insert the charging socket, the valve is rotated around the axis of rotation so as to move the flap from its first configuration to its second configuration.

[0021] According to a characteristic of the invention, the valve comprises at least one arm provided with one end connected to the flap.

[0022] According to a feature of the invention, the end of the arm and the flap are connected by a sliding connection. The arm of the flap comprises a slot and is secured to the flap at a pin. The pin is able to move in the slot when the flap is rotated. It is understood that the pin of the flap and the slot of the arm of the flap are the constituent elements of the sliding connection.

[0023] According to a characteristic of the invention, the valve comprises at least one stop coming into contact with the body of the connection system when the valve is in its second position. This stop makes it possible to limit the translation of the flap along the translation axis. It is understood that when the stop of the flap comes into contact with the body, the flap is in its second configuration and the valve in its second position.

[0024] According to a characteristic of the invention, the connection system comprises at least one return member configured to return the valve from its second position to its first position.

[0025] According to a characteristic of the invention, the return member is centered on the axis of rotation of the valve.

[0026] According to a characteristic of the invention, the return member is in contact at least with the body and the valve.

[0027] The return member is a torsion spring comprising a wound portion centered on the axis of rotation of the valve and two portions tangent to the wound portion. One of the portions tangent to the wound portion is in contact with the valve and the other is in contact with the body of the connection system.

[0028] The return of the shutter from its second configuration to its first configuration is controlled by the return of the valve from its second position to its first position.

[0029] The invention also relates to a connection assembly comprising a charging socket and a connection system conforming to any one of the preceding characteristics, the charging socket being intended to be electrically connected to the connection system, the flap being opposite one of said connection zones when said flap is in its first configuration and the flap being offset relative to said connection zone when said flap is in its second configuration, the charging socket being electrically connected to the connection system when the flap is in its second configuration and the charging socket being electrically disconnected relative to the connection system when the flap is in its first configuration.

[0030] The electrical connection between the charging socket and the connection system is made by plugging the charging socket into the connection system, i.e. by inserting the charging socket into the connection system. For this purpose, the connection system is complementary to the charging socket to enable such insertion.

[0031] When the shutter is in first configuration, the charging socket cannot electrically connect with the connection system, the charging socket is then disconnected from the connection system.

[0032] Other characteristics, details and advantages of the invention will emerge more clearly on reading the description which follows on the one hand, and several examples of embodiment given for informational and non-limiting purposes with reference to the appended schematic drawings on the other hand, in which:

[0038] 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 or to differentiate the invention from the state of the art.

[0039] In the figures, the elements common to several figures retain the same reference. Furthermore, in the description which follows, reference will be made to an orientation which is a function of the Longitudinal, Vertical and Transverse axes as they are arbitrarily defined by the trihedron L, V, T represented in figures 2 to 5, the longitudinal direction corresponding to the direction of principal elongation of the connection system. The choice of names for these axes is not limiting of the orientation which the connection system can take in its application.

[0040] Figure 1 illustrates a charging socket 2 intended to connect to a connection system according to the present invention. In the embodiment shown, the charging socket 2 is a plug-in device of a charging terminal capable of being connected to an electric or hybrid vehicle. More specifically, the charging socket 2 is intended to connect to a connection system of an electric or hybrid vehicle in order to allow an electric current to flow from the charging terminal to an electrical energy storage means, such as batteries, or vice versa.

[0041] This charging socket 2 comprises a protective sheath 4 in which a plurality of electrical cables circulate, not shown here, connected by one end to the charging terminal and by an opposite free end to at least one electrical terminal. In the embodiment shown, the charging socket 2 comprises a first set of electrical terminals 6 and a second set of electrical terminals 8 juxtaposed next to each other.

[0042] It should be noted that, in the embodiment shown, the charging socket 2 is of the CCS Combo 2 connector type, without departing from the context of the present invention, the charging socket 2 may be, for example, of the IEC Type 2 connector type. The specificity of these connectors is well known from the prior art and will therefore not be developed here.

[0043] The first set of electrical terminals 6 here comprises a proximity pilot 10, a control pilot 12 and a ground 14. The second set of electrical terminals 8 comprises a positive phase connector 16 and a negative phase connector 18. It is understood that the charging socket 2 is capable of delivering a direct electric current by means of the second set of electrical terminals 8. Alternatively, the charging socket 2 may be capable of delivering an alternating electric current, if necessary, the charging socket 2 then comprises a single set of electrical terminals, here the first set of electrical terminals 6. Furthermore, the protective sheath 4 is continued by a sleeve 20 extending from the free end to a stop wall 22.This stop wall 22 is intended to come into contact with a body of the vehicle connection system, which will be described in more detail in the description which follows, when the charging socket 2 is connected to the connection system.

[0044] Figure 2 illustrates a connection system 24 according to one embodiment of the invention. The connection system 24 extends in a longitudinal main elongation direction, i.e. parallel to the axis L. The connection system 24 comprises a body 26 within which a first connection zone 28 and a second connection zone 30 are provided. The first connection zone 28 and the second connection zone 30 are superimposed on each other in the longitudinal main elongation direction of the connection system 24.

[0045] As seen in more detail in Figure 3, the first connection area 28 and the second connection area 30 comprise a plurality of connection pins 31. Among the plurality of connection pins 31, the first connection area 28 comprises a pilot pin, a proximity pin, a ground pin, three pins capable of circulating three-phase electrical energy and a neutral pin. Among the plurality of connection pins 31, the second connection area 30 comprises a positive pin and a negative pin.

[0046] Each of these connection pins 31 is complementary to an electrical terminal of the charging socket 2. More specifically, each connection pin 31 of the first connection area 28 is complementary to an electrical terminal of the first set of electrical terminals 6 and each connection pin 31 of the second connection area 8 is complementary to an electrical terminal of the second set of electrical terminals 8.

[0047] It is understood on the one hand that the first connection zone 28 is complementary to the first set of electrical terminals 6 and that the second connection zone 30 is complementary to the second set of electrical terminals 8. It is also understood that the first connection zone 28 is an alternating electric current supply zone and the second connection zone 30 is a direct electric current supply zone.

[0048] Each connection pin 31 extends in a direction of elongation perpendicular to the main direction of elongation of the connection system 24. More specifically, this main direction of elongation of the connection pins 31 is parallel to the direction of elongation of the complementary electrical terminals of the associated set of electrical terminals.

[0049] Furthermore, Figure 2 shows the connection system 24 when an electrical connection between the second connection area 30 and the charging socket 2 is prohibited and Figure 3 shows the connection system 24 when an electrical connection between the second connection area 30 and the charging socket 2 is permitted.

[0050] The connection system 24 comprises a cover 32 intended to prohibit or authorize an electrical connection between the first connection zone 28 and the first set of electrical terminals 6 and a flap 34 intended to prohibit or authorize an electrical connection between the second connection zone 30 and the second set of electrical terminals 8.

[0051] More specifically, the flap 34 is, like the cover 32, capable of taking a first configuration in which the flap 34 prohibits an electrical connection between the associated connection zone, i.e. here the second connection zone 30, and the set of electrical terminals associated with said connection zone, i.e. here the second set of electrical terminals 8.

[0052] Furthermore, the body 26 comprises tabs 36 extending perpendicularly to the main longitudinal elongation direction of the connection system 24 and distributed on either side of the first connection zone 28 and the second connection zone 30. In the embodiment shown, the body 26 comprises eight tabs 36 distributed equally on either side of the first and second connection zones 28, 30 and being aligned transversely in pairs.

[0053] At least some of the tabs 36, here each tab 36, comprise a through-orifice extending radially relative to an axis extending secantly to the direction of elongation of the connection pins 31, and more precisely parallel to the main longitudinal direction of elongation of the connection system 24. More specifically, the orifices of the tabs 36 distributed on the same side of the first connection zone 28 and of the second connection zone 30 are centered around the same axis so that a guide element 38 can be carried by the body 26 by passing through the tabs 36 by means of said orifices.

[0054] It is understood that the guide element 38 extends parallel to the axis with respect to which the orifices of the legs 36 are centered. In other words, the guide element 38 extends along a straight line intersecting the direction of elongation of a connection pin 31 of the connection zone 28, 30.

[0055] In the embodiment shown, the connection system 24 comprises two guide elements 38 distributed on either side of the first connection zone 28 and the second connection zone 30.

[0056] In addition, the cover 32 and the flap 34 are connected to at least one guide element 38 and movable relative to said guide element 38. More specifically, the flap 34 comprises a passage extending in the material of the flap 34 parallel to the straight line along which said guide element 38 extends. This passage allows the guide element 38 to pass through the flap 34 and thus the flap 34 to be connected to the guide element 38. The cover 32 also comprises a passage through which a guide element 38 extends.

[0057] Opposite each of the ends of the passage provided in the flap 34 is a tab 36 distinct from one another. These tabs 36 are arranged at a distance from one another equal to at least twice the length of the passage provided in the flap 34 and equal to at least the dimension of the connection zone 30, arranged opposite the flap 34, in the direction of main longitudinal elongation of the connection system 24.

[0058] This arrangement of the tabs 36 allows the flap 34 to be able to translate along the guide element 38, and more precisely the flap 34 to be able to take a first configuration in which the flap 34 is opposite the connection zone 30 and a second configuration in which the flap 34 is offset relative to said connection zone 30 in a direction parallel to the straight line along which a guide element 38 extends.

[0059] In the embodiment shown, the flap 34 is connected, as described previously, to two guide elements 38 arranged on either side of the first connection zone 28 and the second connection zone 30. It is understood that, in the embodiment shown, the flap 34 is only capable of translating along the guide elements 38.

[0060] In the embodiment shown, the cover 32 also includes a passage through which a guide element 38 extends. The cover 32 is connected to a single guide element 38. Like the passage in the flap 34, each end of the passage in the cover 32 faces a separate tab 36 when the cover 32 is in its first configuration. However, the distance measured along the straight line along which the guide element 38 extends between these tabs 36 is just greater than the length of the passage in the cover 32. As a result, the cover 32 is constrained between the two tabs 36. In other words, the cover 32 cannot translate along the guide element 38, although a slight translation resulting from manufacturing tolerances and a distance limiting the friction forces between the cover 32 and the tabs 36 may be possible.

[0061] The end opposite said passage of the cover 32, that is to say the end located at the level of the other guide element 38, comprises a half-passage capable of reversibly engaging the guide element 38. Such a conformation of the cover 32 allows it to be movable in rotation around the guide element 38 passing through the passage.

[0062] A cross-examination of Figure 2 and Figure 3 makes it possible to highlight that the dimensions of the flap 34 are advantageously designed to be complementary to the dimensions of the second connection zone 30. Similarly, the dimensions of the cover 32 are designed to be complementary to the dimensions of the first connection zone 28.

[0063] It should be noted that the part of the flap 34 proximal to the first connection zone 28 has an arcuate recess to allow an electrical terminal to be inserted into the first connection zone 28 while the flap 34 is facing the second connection zone 30. It should also be noted that when the cover 32 is facing the first connection zone 28 and the flap 34 is facing the second connection zone 30, a part of the cover 32 comes opposite the arcuate recess of the flap 34.

[0064] Furthermore, the connection system 24 comprises a valve 40 extending transversely over the entire transverse dimension of the flap 34 and opposite the flap 34. This valve 40 makes it possible to control the flap 34 and more specifically the configuration of this flap 34.

[0065] For this purpose, the valve 40 comprises at least one arm 42, one end of which is connected to the flap 34. In the embodiment shown, the valve 40 comprises two arms 42 distributed at the transverse ends of the valve 40. It is understood that, in the embodiment shown, each arm 42 is connected to a separate and opposite side of the flap 34.

[0066] At this end of an arm 42 of the valve 40 a pin 44 of the flap 34 slides in a slot 46 formed in said end of the arm 42 so that the pin 44 is able to move in the slot 46. This pin 44 projects from the wall of the flap 34 delimiting a passage within which the guide element 38 extends. It is understood that the valve 40 and the flap 34 are connected to each other by a sliding connection, which will be described in more detail in the description which follows.

[0067] The valve 40 is rotatable about an axis of rotation 48 extending transversely, that is to say perpendicular to the main longitudinal elongation direction of the connection system 24 and perpendicular to the elongation direction of the connection pins 31. More specifically, the body 26 comprises a portion 50 extending along a direction secant to the main longitudinal elongation direction of the connection system 24. This portion 50 of the body 26 carries a shaft 52 about which the valve 40 is rotatable. It is understood that the shaft 52 is coaxial with the axis of rotation 48. In addition, this shaft 52 makes it possible to make the valve 40 integral with the portion 50 and therefore with the body 26.

[0068] The valve 40 comprises guide flanks 54 arranged at the transverse ends of the valve 40, the at least one arm 42 being integral with a guide flank 54. The guide flanks 54 make it possible to limit a potential pivoting of the valve 40 distinct from the rotation around the axis of rotation 48.

[0069] As seen in Figure 2, the flap 34 is, like the cover 32, in a first configuration in which the flap 34 prohibits an electrical connection between the second connection zone 30 and the second set of electrical terminals 8.

[0070] As seen in Figure 3, the flap 34 is, like the cover 32, in a second configuration in which the flap 34 allows an electrical connection between the second connection zone 30 and the second set of electrical terminals 8.

[0071] The change in configuration of the flap 34 is, as mentioned previously, controlled by the valve 40. More precisely, the valve 40 is able to take a first position, visible in FIG. 2, in which the flap 34 is in its first configuration and a second position, visible in FIG. 3, in which the flap 34 is in its second configuration.

[0072] As illustrated in more detail in Figure 4 of a connection assembly 49 formed of the charging socket 2 and the connection system 24, the change in position of the valve 40 is modulated by the connection or disconnection of the charging socket 2 relative to the connection system 24. More specifically, in the embodiment shown, during the insertion of a charging socket 2 comprising a second set of electrical terminals 8 intended to connect with the second connection zone 30, a portion of this second electrical terminal 8 comes into contact with the valve 40 which is in its first position. As the second electrical terminal 8 is inserted into the second connection zone 30, the valve 40 is rotated about the axis of rotation 48 and gradually passes from its first position to its second position.When moving from its first position to its second position, the arms 42 carry with them the pins 44 and the flap 34 translates along the guide elements 38, thus moving from its first configuration to its second configuration.

[0073] It is also understood that the circulation of the pins 44 in the light 44 of the associated arm 42 makes it possible to take into account the constraint exerted by the arm 42 on the pin 44, in particular the difference in position linked to the translation of the flap 34 and the rotation of the arms 42.

[0074] It should be noted that in the case of a charging socket which would be devoid of the second set of electrical terminals 8, the valve 40 would not be actuated by this charging socket during the electrical connection of the latter with the connection system 24. Indeed, such a charging socket comprises only the first set of electrical terminals 6, no second set of electrical terminals 8 would come into contact with the valve 40 for the actuation of the flap 34. In other words, during an electrical connection of such a charging socket with the connection system 24, the valve 40 would remain in its first position and therefore the flap 34 in its first configuration.

[0075] Furthermore, the valve 40 comprises stops 56 which, when the valve 40 is in its second position, come into contact with the portion 50 of the body 26 carrying the shaft 52.

[0076] By removing the second set of electrical terminals 8 from the second connection zone 30, at least one return member 58, here two return members 58 visible in FIG. 5, make it possible to return the valve 40 from its second position to its first position, thus returning the flap 34 from its second configuration to its first configuration.

[0077] The return members 58 surround the shaft 52 and are in contact with the body 26, and more precisely with the portion 50 of the body 26 carrying the shaft 52, and the flap 34. In the embodiment shown, the return members 58 are torsion springs surrounding the shaft 52 in a helix with projecting elements coming into contact with the flap 34 and the body 26.

[0078] It should be noted that in an alternative embodiment of the invention, the flap 34 and the valve 40 may also be associated with the first connection zone 28 by operating in a similar manner to what has just been described. In addition, in another alternative embodiment of the invention, the connection system 24 may comprise two flaps 34, each controlled by a separate valve 40. One flap 34 is then associated with the first connection zone 28 and the other flap 34 is associated with the second connection zone 30. It appears from the preceding description that the invention indeed achieves the aim it set for itself by proposing a connection system capable of prohibiting or authorizing an electrical connection whose operation allows a single hand to be used during charging.

[0079] The invention as just described cannot, however, be limited to the means and configurations exclusively described and illustrated, and also applies to all equivalent means or configurations and to any combination of such means or configurations.
