[0039] The following references Figure 1 An example of a vehicle 100 is described which is equipped with one embodiment of an arrangement for unlocking a front bonnet.

[0040] The motor vehicle 100 is any type of motor vehicle, in particular a passenger vehicle or a utility vehicle. The motor vehicle 100 may be equipped with a combustion engine and / or an electric motor.

[0041] In the rest of this document, the figures are referenced by Figure 2 The illustrated directly orthogonal reference system (X, Y, Z) is defined wherein axis X is parallel to the longitudinal axis of motor vehicle 100 and oriented toward the rear of motor vehicle 100 and axis Z is vertical and oriented toward the top of the vehicle.

[0042] The motor vehicle 100 comprises a passenger compartment 4 and a front hood 2. The front hood comprises at least one lock 21 which ensures opening of the hood 2. The lock 21 is connected to an arrangement 1 for unlocking the lock 21.

[0043] In one embodiment, the motor vehicle 100 may include a fitting that may be used as a storage compartment 23 , in particular for storing cables for connecting the vehicle to the charging terminals.

[0044] 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 in the passenger compartment 4 of the vehicle 100. Thus, the cable is positioned entirely outside the passenger compartment 4.

[0045] In one embodiment, the gripping device is located at the front hood 2 or in a region close to the front hood 2 of the vehicle, in particular at the front fender 5 or the front bumper or the front grille.

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

[0047] Thus, after applying a pulling force to the gripping device, the user moves towards 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. As an alternative, the hood 2 can, for example, additionally include a lock catch 22. In this case, when the lock 21 is unlocked, the hood is partially opened. In order to fully open the front hood 2, the user must then unlock the lock catch 22 by putting his hand into the opening of the hood.

[0048] Figures 3 to 6 A first embodiment of the arrangement 1 is shown in FIG. In this embodiment, the gripping device 11 comprises two cutouts or loops 111, 112, which are respectively intended to allow two fingers of a user's hand to pass through. The gripping device 11 can also be described as a handle or a lever with a hole, which is particularly omega-shaped, for allowing the best two fingers of a user's hand to pass through.

[0049] The gripping device 11 is connected to a cable 12 which is concealed by its sheath 121 .

[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 means 11 , the safety element is said to be “disengaged”; and

[0053] - When the safety element prevents the use of the gripping means 11 , the safety element is said to be “engaged”.

[0054] Figures 3 to 6 A first embodiment of a security element 13 is shown in FIG.

[0055] The fixed part 131 is fixed to a fixed and rigid structure of the motor vehicle. Figure 7 In FIG. 1 , the safety element 13 is shown on the inside of the charging port. According to a variant embodiment not shown, it can be fixed to a body structure portion adjacent to the charging port 6 . The fixed portion 131 contains the mechanism controlling the movable portion 132 .

[0056] The movable part 132 comprises a pin 1321 which is retractable in a first direction 1322. The movable part 132 also comprises two fins 1323 which are diametrically opposed with respect to the retractable pin 1321 and which are rotatable about the direction 1322.

[0057] This mechanism is often referred to as a "push-pull mechanism". Under pressure on the end of the movable portion 132, the retractable pin is pulled back and pivoted, thereby rotating the fin 90 degrees. When the pressure is released, the pin 1321 extends.

[0058] The movable portion 132 is intended to cooperate with a mating portion 113 provided in the gripping device 11 so that together they form a connection means between the safety element 13 and the gripping device 11. The mating portion 113 provides the female part of the connection means, while the movable portion 132 provides the male part of the connection means.

[0059] When the safety element 13 is engaged, as Figure 3 and Figure 4 As shown, the pin 1321 remains pulled back and the fin 1323 is locked in the mating portion 113 of the gripping device 11. Thus, the gripping device 11 is fixed to the safety element 13, which itself is fixed to a fixed and rigid structure of the motor vehicle. Thus, when the safety element 13 is engaged, it is not possible to use the gripping device to apply tension to the cable 12.

[0060] Conversely, when the safety element 13 is disengaged, as shown in FIG. Figure 5 and Figure 6 As shown, when the user presses on the end of the retractable pin, the fin 1323 rotates 90 degrees and this allows the fin to come out of the fitting 113. In addition, the pin 1321 spreads out, thereby forming a space between the gripping device 11 and the safety element 13. The user can then grip the gripping device more easily.

[0061] Figure 7 and Figure 8 The situation in which the safety element 13 is fixed to the inner wall 62 of the charging port 6 of the electric vehicle is shown.

[0062] exist Figure 7 In the embodiment, the safety element 13 holds the gripping device 11 against the inner wall 62, that is to say in the retracted position. It should be noted that the illustrated situation may correspond to

[0063] - engagement of the safety element 13, in which case pressure on the safety element 13 via the gripping means 11 will not release the gripping means 11, or

[0064] - Disengagement of the safety element 13 , in which case pressure on the safety element 13 via the gripping means 11 will release the gripping means 11 .

[0065] exist Figure 8 In the embodiment, the safety element 13 keeps the gripping device 11 away from the inner wall 62, that is to say in the deployed position. Then, the safety element 13 is disengaged.

[0066] In a preferred embodiment, the motor vehicle further comprises a vehicle-user authentication device 3 which controls the security element 13 so that

[0067] - if the user of the vehicle is authenticated in the vicinity of the vehicle, the safety element 13 is disengaged,

[0068] - Otherwise, the safety element 13 is engaged.

[0069] Therefore, the grip device 11 can be used only when a person near the vehicle is identified as a user of the vehicle by the authentication device 3 .

[0070] The user authentication device 3 may, for example, recognize a magnetic card or a key, more generally any object used to identify a person, thereby enabling 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 opening door leaf of the vehicle is unlocked.

[0071] Other embodiments of the authentication device 3 are conceivable.

[0072] In an advantageous embodiment, the vehicle 100 is an electric vehicle and the gripping device 11 is arranged inside a charging port 6 of the vehicle 100 .

[0073] The following references Figures 7 to 11 A first embodiment of an assembly 1 is described, which comprises a gripping device 11 arranged in a charging port 6. In this embodiment, the assembly 1 comprises a safety element 13, such as Figures 3 to 6 shown.

[0074] The port 6 comprises a flap 61 with an interior lining 611. The port 6 further comprises an interior wall 62 or bowl 62. The bowl 62 is a rigid wall that supports, among other things, an electrical charging plug interface 621. The bowl 62 defines a boundary between the engine / motor area of ​​the vehicle and the interior of the charging port 6.

[0075] The sheath 121 of the cable 12 is fixed to the bowl 62. In the embodiment described, the assembly 1 makes it possible to deflect the cable 12 in its sheath 121 by 20 millimeters by pulling the gripping means 11.

[0076] The safety element 13 is integrally mounted with the bowl 62. Figure 7 and Figure 8 As shown, the safety element 13 passes through the bowl 62 such that a fixed portion 131 of the safety element 13 is in the engine / motor area and a movable portion 132 of the safety element 13 is inside the charging port.

[0077] The gripping device 11 is arranged such that the recess 113 can cooperate with the movable portion 132 of the safety element 13 .

[0078] The bowl 62 also includes a counterpart 622 of the gripping device 11. Figure 7 and Figure 8 The pairing form 622 shown more particularly in FIG. 1 is designed to enclose the gripping device when the gripping device 11 is locked by the security element 13, that is to say when the authentication device 3 does not detect a vehicle user near the vehicle. In these same cases, the pairing form also encloses the end of the security element 13.

[0079] When the flap 61 of the port remains open to charge the vehicle, and when the user of the vehicle is not present, the unlocking device 11 and the security element 13 must be protected from fraudulent users. Fig. 9 As shown, the protection is provided by the mating form 622. This is because the presence of the mating form 622 makes it difficult to break the security element 13 and it is impossible for the user to put their fingers into the opening of the gripping device 11.

[0080] In the first embodiment, the inner lining 611 of the port 6 has been defined to bring the gripping device 11 into the retracted position when the user closes the charging port 6 of the motor vehicle 100. In other words, if the user forgets to put the gripping device 11 back into the retracted position before closing the charging port 6, the lining will mechanically exert pressure on the safety element 13 via the gripping device 11 when the port is closed.

[0081] The following references Figure 12 to Figure 14 A second embodiment of an assembly 1 is described, which comprises a gripping device 11 arranged in a charging port 6 .

[0082] In this embodiment, the safety element 13 is located completely behind the bowl of the port 6 and this protects it from any deliberate damage in the event of an attempt to illegally use the gripping device 11 .

[0083] The safety element 13 comprises mechanical fingers 135 which are deployed when the safety element 13 is engaged and which are retracted when the safety element 13 is disengaged.

[0084] The gripping device 11 is arranged to pass through the bowl of the port 6. The gripping device thus comprises an outer part 114 located in the space defined by the port 6 and an inner part 115 located behind the bowl of the port 6. During use, the gripping device slides along a guide 623 provided in the bowl 62. The amplitude of the movement of the gripping device 11 in the guide 623 corresponds to the deflection of the cable 12 in its sheath 121, i.e. an amplitude of 20 mm, for example.

[0085] The inner portion 115 of the gripping device 11 comprises an opening 116 for the passage of a mechanical finger 135 of the safety element 13 .

[0086] The tension exerted by the cable 12 systematically forces the gripping device 11 against the entrance of the guide 623. As a result, once the user releases the gripping device 11, the opening 116 is repositioned to face the mechanical finger 135. After use, the gripping device 11 is thus automatically repositioned to allow activation of the safety element 13.

[0087] The following references Fig.15 An embodiment of a method according to the invention for unlocking a front bonnet 2 of a motor vehicle 100 comprising an arrangement 1 is described.

[0088] The method comprises an unlocking step E13 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 .

[0089] To be able to apply the pulling force, the user must disengage the security element 13 of the arrangement 1 in a first sub-step E11. In one embodiment, the disengagement is achieved by means of a magnetic key fob or a magnetic key, which can be a key or a key fob for unlocking the vehicle, more generally any identification item.

[0090] Then, if arrangement 1 has been implemented according to the first embodiment, that is to say an arrangement with a "push-pull" type mechanism, the user must in a second sub-step E12 exert pressure on the gripping means 11 in order to release the gripping means from its recess. If arrangement 1 has been implemented according to the second embodiment, sub-step E12 is not necessary, since the gripping means 11 are directly accessible.

[0091] Then, in a third sub-step E13, the user exerts a pulling force on the gripping device 11, causing the cable 12 of the arrangement 1 to move in translation. In one embodiment, the deflection of the cable 12 is of the order of a few centimeters, for example two centimeters. The tension exerted by the cable 12 on the gripping device 13 automatically returns the gripping device 11 to the position it occupied before the pulling force was applied. The lock 21 of the front hood 2 is then unlocked.

[0092] Then, if arrangement 1 has been implemented according to the first embodiment, in a fourth sub-step E14, the user exerts pressure on the gripping means 11 in order to put it back into its recess. In a variant, the gripping means 11 can be put back into its recess mechanically, for example when the port containing the gripping means 11 is closed. The internal lining of the flap of the port can advantageously be designed to exert pressure on the gripping means 11 in order to put it back into its recess.

[0093] If arrangement 1 has been implemented according to the second embodiment, the fourth sub-step is not necessary.

[0094] The following references Fig.16 One embodiment of a method for charging an electric motor vehicle 100 according to the present invention is described.

[0095] 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 means for authenticating the user, using for example a magnetic key fob or a magnetic key.

[0096] 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 hood 2 of the vehicle.

[0097] The second step E22 is decomposed into four sub-steps E11 to E14, which are described above in the embodiment of the method for unlocking the front hood. It should be noted that the sub-step E11 of disengaging 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 magnetic key fob or the same magnetic key, more generally any identification item making it possible to unlock the port 6 and disengage the security element 13. At the end of step E22, the lock 21 of the front hood 2 is unlocked.

[0098] In a third step E23, the user grabs the charging cable in the recess 23 located under the front hood 2 of the vehicle. To do this, the user moves from the port 6 towards the front hood 2 of the vehicle. They then open the front hood 2 (previously unlocked during step E22) in order to grab the cable and close the front hood 2 again.

[0099] In a fourth step E24 , the user connects the electric vehicle charging terminal to the charging interface 621 of the port 6 via a charging cable.

[0100] In a fifth step E25, the gripping means 11 are blocked while the vehicle is being charged. 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 means 3 detects the absence of the user and automatically locks the vehicle. In a preferred embodiment, the authentication means 3 also engages a security element 13 arranged so that the gripping means 11 cannot be used to unlock the front hood of the vehicle while it is being charged.

[0101] Finally, the arrangement 1 according to the invention makes it possible to install the front bonnet unlocking system outside the passenger compartment 2. This arrangement thus avoids the need for a user who has left the vehicle to return to the passenger compartment to activate the bonnet opening mechanism.

[0102] Thus, a user who has exited their vehicle (eg, to access a charging terminal) does not need to return to the vehicle's passenger compartment to retrieve a charging cable stored under the vehicle's front hood.

[0103] Advantageously, the arrangement 1 can be installed in an electrical charging port and this reduces the number of times a user has to move around their vehicle while the vehicle is being charged.

[0104] If the arrangement 1 is mounted near the front hood, the invention additionally makes it possible to reduce the length of the cable connecting the hood lock to the cable pull rod and also to reduce the length of the sheath of this cable. A smaller cable makes it possible to have a better effect on the unlocking, because the cable tension can be lower and the cable travel can be shorter.

[0105] Embodiments of the arrangement 1 also make it possible to ensure access to the engine / motor compartment. In particular, the invention hinders attempts to fraudulently use the arrangement 1 .

[0106] Furthermore, the costs of implementing the invention are limited. This is because the invention neither changes the technical features of the front hood 2 and the lock 21 nor modifies their design. Furthermore, the proposed solution reuses mechanisms already present on the vehicle, especially in the first embodiment of arrangement 1, where the "push-pull" system used as safety element 13 is the same as that used to secure the flap of the port 6. The same applies to the locking system of the second embodiment, which is a safety element that can also be used to ensure that the plug is connected to the charging interface 621 when the vehicle is being charged.

[0107] In addition, the assembly of the vehicle can be simplified. This is because the arrangement 1 can advantageously be arranged so that the cables do not pass through the passenger compartment. In other words, it is no longer necessary to extend the cables through the dashboard of the vehicle between the dry area and the wet area.
