[0035] The following references Figure 1 An example of a vehicle 100 is described which is equipped with an embodiment of an arrangement for unlocking a front bonnet.

[0036] The motor vehicle 100 is any type of motor vehicle, including a passenger vehicle or a utility vehicle. The motor vehicle 100 may be equipped with a combustion engine and / or an electric engine.

[0037] In the rest of this paper, the diagrams are Figure 2 1. The axial direction of the motor vehicle 100 is defined by a directly orthogonal reference system (X, Y, Z) represented, with the axis X being parallel to the longitudinal axis of the motor vehicle 100 and oriented toward the rear of the motor vehicle 100, and the axis Z being vertical and oriented toward the top of the vehicle.

[0038] The motor vehicle 100 comprises a passenger compartment 4 and a front bonnet 2. The front bonnet comprises at least one lock 21 which ensures opening of the bonnet 2. The lock 21 is connected to an arrangement 1 for unlocking the lock 21.

[0039] In one embodiment, the motor vehicle 100 may comprise a space which may be used as a storage compartment 23 , in particular for storing cables for connecting the vehicle to charging terminals. The storage compartment 23 is located in a container accessible by opening the front bonnet 2 .

[0040] The arrangement 1 comprises a gripping device 11 and a cable 12 connecting a lock 21 to the gripping device 11. The gripping device 11 is accessible to a user from outside the passenger compartment 4 and no part of the cable is located inside the passenger compartment 4 of the vehicle 100. Thus, the cable is located entirely outside the passenger compartment 4.

[0041] The gripping device 11 is located at an end 6 which is located in the area close to the front bonnet 2 of the vehicle, in particular on the front wing 5 or the front bumper or the front grille of the vehicle.

[0042] In an advantageous embodiment, the vehicle 100 is an electric vehicle and the gripping device 11 is a charging port 6 of the vehicle 100 .

[0043] The port 6 comprises a flap 61 having a decorative portion 611 visible from the outside and an inner lining 612. The port 6 further comprises an inner wall or bowl 62. As particularly shown in Figure 4 , Figure 5 and Figure 8As can be seen in the figure, the bowl 62 is a rigid end wall 621 which in particular supports an electric charging plug interface 622. The end wall 621 thus comprises an opening having a shape complementary to that of the interface 622 which is intended to be connected to the electric charging plug 7, as in Figure 7 The bowl 62 is shaped according to the opening formed in the front wing so that it can be mounted from the outside in such a way that in the closed position of the charging port 6, the charging port is flush with the front wing 5, as shown in FIG. Figure 3 shown.

[0044] The charging port 6 comprises a flap 61 rotatably hinged on a bowl 62 about an axis AA. The flap 61 in the closed position is connected to the bowl by a locking / unlocking device 30, which is usually called a "push-pull mechanism" and is located on the side opposite to the rotation axis AA. When the flap 61 is pressed into alignment with the locking mechanism, a retractable finger comprising radial fins moves backwards and pivots, causing a 90-degree rotational movement of the fins, thereby releasing the connection between the flap 61 and the locking mechanism. When the bearing pressure is released, the retractable finger exerts a thrust so as to place the flap 61 in a slightly open position, which then makes it easier for the user to grasp it.

[0045] The locking / unlocking device 30 is assembled to the end wall 621 of the bowl 62, in particular as in Figure 5 can be seen in.

[0046] The arrangement 1 and the lock 21 interact such that a pulling force exerted by a user via the gripping device 11 on the cable 12 unlocks the lock 21 .

[0047] Therefore, after applying a pulling force to the gripping device, the user moves toward the front hood 2 located near the gripping device 11. In one embodiment of the front hood 2, the user can then directly open the front hood 2. Alternatively, the hood 2 may, for example, further include a latch 22. In this case, when the lock 21 is unlocked, the hood is slightly opened. In order to fully open the front hood 2, the user must unlock the latch 22 by passing his hand through the hood opening.

[0048] Figures 3 to 8 An embodiment of an arrangement 1 is shown in . According to this arrangement 1 , the gripping means 11 is a flap 61 of the port, which can also be described as a handle or paddle operable by the hand of the user.

[0049] The gripping device 11 is connected to the cable 12 , which is concealed by its sheath 122 .

[0050] The arrangement 1 advantageously comprises a safety element 13 intended to prevent unauthorized use of the gripping device 11 .

[0051] In the rest of this article,

[0052] - when the safety element 13 allows the use of the gripping device 11 , the safety element is said to be “deactivated”; and

[0053] The safety element is said to be “activated” when it prevents the use of the gripping device 11 to unlock the bonnet lock.

[0054] exist Figure 4 and Figure 6 In FIG. 1 , the security element 13 is shown as being in an “enabled” state, while in Figure 8 The safety element comprises a fixed part 131 and a movable part 132 .

[0055] The fixed part 131 is assembled to the bowl 62 of the charging port, and for this purpose the bowl comprises an attachment interface 623 forming a fixed and rigid structure of the bowl 62 . The fixed part 131 contains the mechanism controlling the movable part 132 .

[0056] The movable portion 132 includes a retractable finger that is movable perpendicular to the cable 12 , as will be described in detail below.

[0057] The attachment interface 623 comprises a receiving groove 6231 at the end of the sheath of the cable 12. The groove has a substantially cylindrical profile through which two ribs extend with radial projections, which relative to the movement of the sheath 122 of the cable 12 form an axial retention stop.

[0058] The safety element 13 is arranged below the receiving groove 6231 so that the movable portion 132 is close to the cable 12 in the activated state of the safety device 13 .

[0059] The cable 12 comprises a flexible strand 121, in particular made of metal, such as Figure 4 , Figure 6 and Figure 8 As shown, the slider 123 is crimped onto this flexible strand. The slider 123 has a substantially rectangular geometry and has a space 113 , in particular an opening (eg a through hole), intended to receive the movable portion 132 in the activated state of the safety device 13 .

[0060] The security device 13 is connected to the on-board electronic network via a connector 124 to allow switching between an "activated" state and an "inactivated" state. This connector 124 may be connected to a control unit which may be linked to the authentication device 3 or a remote control (not shown).

[0061] The movable portion 132 is intended to interact with a space formed in the cable 12 so as to form together connection means between the safety element 13 and the cable 12. The space provides the female part of the cable 12, while the movable portion 132 provides the male part of the connection means.

[0062] The cable 12 comprises a flexible strand 121, in particular made of metal, such as Figure 4 , Figure 6 and Figure 8 As shown, the slider 123 is crimped onto this flexible strand. The slider 123 has a substantially rectangular geometry and has a space, in particular an opening (eg a through hole), intended to receive the movable portion 132 in the activated state of the safety device 13 .

[0063] When the security element 13 is enabled, Figure 4 and Figure 6 As shown, the retractable fingers of the movable portion 132 are held protruding inside the slider 123. The cable is attached to a safety element 13 which blocks the cable 12, or at least immobilizes the strands 121 on the safety element 13, which is rigidly fixed to the fixed and rigid structure of the bowl 62. Thus, when the safety element 13 is activated, the strands 121 cannot be moved relative to the sheath of the cable 12.

[0064] Conversely, when the security element 13 is deactivated, as Figure 8 As shown, the slider 123 is no longer engaged with the safety element 13 , leaving the strands 121 free to move relative to the sheath 122 of the cable 12 .

[0065] The flap 61 can adopt three positions:

[0066] - a closed position, in which the electric charging plug interface 622 is not accessible, such as in Figure 3 As can be seen in

[0067] - a stable open position in which the interface 622 is accessible for electrical connection of the charging plug; Figure 5 As can be seen in FIG. 1 , the flap 61 is parallel to the axis BB.

[0068] - For unlocking the front bonnet lock in the maximum open position; Figure 7 and Figure 8 As can be seen in FIG. 6 , the flap 61 is offset relative to its closed position by an opening angle β which is greater than the angle α which the flap 61 occupies in the stable position.

[0069] The stable open state of the flap 61 is obtained by immobilizing the flap 61 via the cable 12 , which is then retained by the safety device 13 .

[0070] The transition from the stable open position to the maximum position for unlocking the front bonnet lock is achieved via a manual action, i.e. Figure 7 The flap 61 is provided with a force in the direction of the arrow F, which causes the flap to rotate about the axis AA. This has the effect of pulling the cable strand 121 relative to the sheath 122 so as to unlock the bonnet lock. For this purpose, the inner lining 611 of the flap 61 comprises an indexing wall 6111 located near the hinge area. The indexing wall 6111 is used to index the cable through which the cable strand 121 extends.

[0071] The indexing wall 6111 has a dual role:

[0072] - the strand 121 of the cable 12 is mounted to slide freely through the indexing arm over a first angular travel between the closed position and the stable open position of the flap 61,

[0073] - Over a second angular travel between the stable open position and the maximum open position, the indexing wall 6111 exerts a tension force on the cable strand 121 via an end stop, in particular a spherical stop, which due to its geometry is also described as an end olive.

[0074] In the closed state, the indexing wall 6111 is positioned close to the attachment interface 623 or even rests against the attachment interface, thereby forming a fixed, rigid and protruding structural part of the bowl 62, as shown in FIG. Figure 4 can be seen in.

[0075] The indexing wall 6111 includes an end face 6112 which extends substantially radially to the hinge region of the inner lining 611 of the flap 61, such as in particular at Figure 5 The end face 6112 is extended towards the rear by a disk portion 6113, the side of which comprises a recess 6114 inside which the strand 121 can be accommodated during manipulation of the gripping device 11. The geometry of the indexing wall 6111 (that is to say the position of the end face and / or the radius of the disk portion 6113) is therefore defined according to the useful travel of the strand 121 for unlocking the front bonnet lock.

[0076] In the closed state, the end stop of the strand 121 moves away from the end face 6112 of the indexing wall 6111, as in Figure 4 can be seen in.

[0077] exist Figure 4 The closed position and Figure 6 Between the stable open positions, the cable strand 121 slides along the end face while being placed inside the groove 6114 of the disk portion 6113 in such a way that in the stable state the end stop of the strand 121 abuts against the end face 6112.

[0078] In the “activated” state of the safety device 13 , the slide is rigidly fixed to the structure of the bowl 62 by means of the retractable fingers of the movable portion 132 of the safety device, which are then in the deployed position.

[0079] In the "deactivated" state of the safety device 13, the gripping device 11 can be pivoted from the stable open position to the maximum position, with the result that the strand 121 is pulled in order to manually unlock the front hood lock by pivoting the flap 61 of the charging port 6. For example, pulling the gripping device 11 (with the strand 121 sliding 20 millimeters in its sheath 122) allows unlocking the lock, which corresponds approximately to Φ=β-α between 10° and 20° around the axis AA.

[0080] In a preferred embodiment, the motor vehicle further comprises an authentication device 3 for authenticating a user of the vehicle controlling the safety element 13, so that

[0081] - if the vehicle user is authenticated in the vicinity of the vehicle, the security element 13 is deactivated,

[0082] - Otherwise, the secure element 13 is enabled.

[0083] Therefore, the gripping device 11 can be used to unlock the front lock only when a person located in the vicinity of the vehicle is recognized by the authentication device 3 as a user of the vehicle.

[0084] The authentication device 3 for authenticating the user of the vehicle is also linked to a locking / unlocking device 30 of the charging port 6 of the vehicle 100 .

[0085] Therefore, the authentication device 3 controls the locking / unlocking device 30 so that

[0086] - if the vehicle user is authenticated in the vicinity of the vehicle, the locking / unlocking device 30 is in the "deactivated" state, making it possible to unlock the closed port 6,

[0087] Otherwise, the locking / unlocking device 30 is in the “activated” state, ie the charging port 6 .

[0088] The authentication device 3 for authenticating the user may for example recognize a magnetic card or a key, more generally any object for identifying a person, thereby allowing the vehicle to be automatically unlocked when the user is within a given perimeter around the vehicle 100 (e.g. less than two meters from the vehicle). In this embodiment, the authentication device may allow the use of the gripping device only when the doors are unlocked.

[0089] Other embodiments of the authentication device 3 are conceivable.

[0090] The bowl 62 may comprise an opening 623 through which the graduated wall 6111 , at least the end face 6112 , can freely circulate, so that the geometry of the bowl has no influence on the geometry of the unlocking means.

[0091] In the event of an attempt to force open the arrangement, resulting in rupture of the flap 61 and the indexing wall 6111 , the cable can be released but cannot be actuated because the safety device 13 remains engaged with the slider 123 , which prevents any relative movement of the strand 121 with respect to the sheath 122 of the cable 12 .

[0092] According to an alternative embodiment not shown, the indexing wall 6111 is shaped so as to move continuously behind the bowl 62, so that the bowl does not have the aforementioned opening. This makes it possible to make the cable 12 and the safety element 13 inaccessible and they are then protected from any fraudulent use when the flap 61 is in a stable open state.

[0093] When the spring of the front bonnet lock exerts a force opposite to the force exerted by the gripping device 11 for unlocking, the strands 121 tend to return the flap 61 from the maximum open position to the stable open position. As a result, as soon as the user releases the gripping device 11, the gripping device 11 thus automatically returns to its stable open position. The cable slider 123 can be positioned again in line with the retractable finger of the movable part 132 so that, in the absence of user authentication, the retractable finger returns to its position protruding inside the slider.

[0094] The following references Fig. 9 A mode of implementation of a method for unlocking a front bonnet 2 of a motor vehicle 100 comprising an arrangement 1 according to the invention is described.

[0095] The method comprises an unlocking step E14 in which the user exerts a pulling force on a gripping device 11 of the arrangement 1 , which is situated outside the passenger compartment 4 ; it is in particular a flap 61 of the charging port 6 .

[0096] To be able to apply the pulling force, the user must deactivate the security device 13 of the arrangement 1 in a first substep E11. In one embodiment, the deactivation is performed using a magnetic fob or a magnetic key, which may be a key or a key fob for unlocking the vehicle, more generally any identification object.

[0097] Next, the user must press on the gripping means 11 in a second sub-step E12 in order to disengage it from the charging port opening, the gripping means 11 then being in a slightly open position so that the user can manipulate it.

[0098] Then, in a third sub-step E13 , the user exerts a rotational force on the flap 61 so that the strands 121 of the cable 12 are seated inside the graduated walls 6111 , the flap 61 then moving from the slightly open position to the stable open position.

[0099] Next, in a fourth sub-step E14, the user applies an additional force greater than that of step E13 and tending to overcome the resistance exerted by the spring of the bonnet lock, so as to move the strand 121 inside the sheath 122, which unlocks the front bonnet lock. Thus, the flap 61 moves between the stable open position and the maximum open position.

[0100] The strand 121 moves about a few centimeters (for example two centimeters) so that the angular travel of the flap 61 between the stable open position and the maximum open position is greater than the few centimeters required to unlock the front hood lock. Once the hood is unlocked, when the user releases the flap, the tension exerted by the strand 121 on the gripping device 11 of the flap 61 type tends to mechanically return the gripping device 11 to the stable open position. The lock 21 of the front hood 2 is then unlocked.

[0101] The following references Fig.10 A mode of implementation of a method according to the invention for charging an electric motor vehicle 100 is described.

[0102] In a first step E21, the user opens the charging port 6 of the motor vehicle 100. In one embodiment, the opening of the port 6 is ensured by user authentication means, using for example a magnetic key fob or a magnetic key.

[0103] In a second step E22 , the user exerts a pulling force on the gripping means 11 of the arrangement 1 in order to unlock the front bonnet 2 of the vehicle.

[0104] The second step E22 is decomposed into four sub-steps E11 to E14, which are described above in the mode of implementation of the method for unlocking the front bonnet. Note that the sub-step E11 of deactivating the security element 13 can advantageously be performed by the same means as those for unlocking the port 6 performed in step E21. In other words, it is the same key fob or the same magnetic key, more generally any identification object that allows the port 6 to be unlocked and the security element 13 to be deactivated. At the end of step E22, the lock 21 of the front bonnet 2 is unlocked.

[0105] In a third step E23, the user grasps the charging cable in a housing 23 located under the front hood 2 of the vehicle. To do this, the user moves from the port 6 of the vehicle to the front hood 2. They then open the front hood 2 (previously unlocked during step E22) to grasp the cable and close the front hood 2. Opening the front hood 2 may require pivoting an additional safety lever of the unlocking latch 22 type mounted on the lock 21.

[0106] In a fourth step E24 , the user connects the electric vehicle charging terminal to the charging interface 622 of the port 6 via a charging cable.

[0107] In a fifth step E25, the connection of the charging cable to the charging interface 622 leaves the strand 121 immobile relative to the port 6. During this step, the user can move away from their vehicle while the port 6 remains open to charge the vehicle. When the user moves away from their vehicle, the authentication device 3 detects that the user has left and activates the security element 13 arranged so that the strand 121 connecting the front hood lock 21 to the gripping device 11 cannot be used to unlock the front hood of the vehicle while the vehicle is being charged.

[0108] Finally, the arrangement 1 according to the invention makes it possible to install a front bonnet unlocking system outside the passenger compartment 2. This arrangement avoids the user, having exited the vehicle, having to return to the passenger compartment to activate the bonnet opening mechanism.

[0109] Thus, a user who has exited their vehicle (eg to access the charging terminals) does not need to return to the passenger compartment of the vehicle if they wish to retrieve a charging cable stored under the front bonnet of the vehicle.

[0110] Advantageously, the arrangement 1 may be mounted at an electric charging port, which reduces the number of times a user must walk around their vehicle when charging it.

[0111] In the case of an arrangement 1 mounted near the front bonnet, the invention also makes it possible to reduce the length of the cable strand 121 connecting the bonnet lock to the flap 61 acting as gripping means 11, and also to reduce the length of the sheath of this cable. A smaller cable allows for a better unlocking action, as the cable tension can be lower and the cable travel can be reduced.

[0112] Embodiments of the arrangement 1 also make it possible to ensure access to the engine compartment. In particular, the invention hinders attempts to fraudulently use the arrangement 1 .

[0113] Furthermore, the costs of implementing the invention are limited. This is because the invention does not modify the technical characteristics or the design of the front bonnet 2 and the lock 21. Furthermore, the proposed solution reuses mechanisms already present on the vehicle, in particular the "push-pull" system used as an element for opening the flap 61 of the port 6 and for securing the flap of the port 6 in the closed state.
