Description

Title of the invention: Lock arrangement for a motor vehicle hood.

[0001] The present invention relates to a lock arrangement for an opening of a motor vehicle, such as a front hood of a motor vehicle.

[0002] It is known per se to have at the front of a motor vehicle with an internal combustion engine a compartment housing the engine which is closed by an opening commonly referred to as a hood.

[0003] Generally, such a hood comprises a fixed edge pivotally mounted on the bodywork by means of hinges known per se and a free edge provided with at least one latch arranged to cooperate with a lock arrangement provided on the bodywork and making it possible to keep the hood in the closed position.

[0004] In order to meet the high requirements in the field of automobile safety, the lock arrangement can be operated in two stages in order to prevent the front hood from opening unexpectedly while the motor vehicle is in motion and from suddenly obstructing the view of the motor driver.

[0005] In traditional vehicles comprising an internal combustion engine housed in the front bonnet, the user of the motor vehicle first carries out a first manoeuvre which is carried out at a distance from the bonnet and by actuating a lever housed inside the passenger compartment of the vehicle, which has the effect of actuating a bonnet ejection mechanism in a slightly half-open configuration.

[0006] Then, in order to completely free the hood opening, the user carries out a second maneuver which requires him to get out of the motor vehicle to operate an operating lever located under the hood, the arrangement of which varies according to the type of motor vehicle and which the user often has to search for "blindly" by sweeping with his hand.

[0007] In recent years, the fight against air pollution has led car manufacturers to develop mass-produced electric vehicles with an electric motor as the sole means of drive and in which a battery is mounted in the floor of the body of these vehicles, thus freeing up the space traditionally occupied by the engine block.

[0008] The space thus freed up at the front of the electric vehicle is used to form a trunk, for example for luggage. As this trunk is used at the front of the motor vehicle, it is commonly referred to by the Anglo-Saxon expression "front trunk" or by its contraction "frunk".

[0009] It is therefore understood that this new use of the space in front of the motor vehicle has profoundly modified the use and frequency of opening the front hood. Consequently, the traditional hood opening maneuver requiring the user to get out of the motor vehicle appears to be poorly ergonomic and is perceived as inconvenient or even uncomfortable and also reflects a perception of poor quality of the motor vehicle.

[0010] An aim of the present invention is to propose a lock arrangement which makes it possible to increase the comfort of use of a trunk provided with a front hood of a motor vehicle and to adapt its operation for frequent and regular use, while respecting the safety constraints inherent in the automotive field.

[0011] A lock for a motor vehicle engine hood is already known from the prior art, comprising a fork-shaped latch which retains a striker of the engine hood and a locking pawl which blocks the latch in the closed position. The pawl is actuated, for example, using an actuating lever to sequentially adopt, with the striker, a closing configuration for engaging the striker by the fork and an unlocking configuration for releasing the striker allowing the hood to be lifted.

[0012] Generally, the lock further comprises an ejector which is configured to interact with the latch so that the latch is pivoted by the ejector to a position for releasing the striker by the latch. The ejector is also elastically returned in the ejection direction by an ejection spring which allows the striker to be ejected and allows the hood to be lifted.

[0013] The disadvantage of the current solution proposed in the state of the art is that the lock arrangement is relatively bulky because it requires the use of several locking members in order to provide additional security in the event of failure of one of the locking members. Description of the invention

[0014] The present invention aims to remedy these drawbacks.

[0015] To this end, the invention relates to a lock arrangement for a motor vehicle hood comprising: - a pivotally mounted latch comprising a notch capable of cooperating with the hood by engaging a hood latch in the notch; - a locking pawl cooperating with the latch between an initial configuration of locking the latch in total engagement of the strike, an intermediate configuration of locking the latch in partial engagement of the strike and a final configuration of unlocking the latch in total release of the strike, the pawl being configured to be coupled to an actuator for selectively rotating the pawl from the initial configuration to the intermediate configuration following a first control action of the actuator and from the intermediate configuration to the unlocking configuration following a second control action of the actuator, characterized in that the latch, called a combined latch, is produced in the form of a double latch comprising at least a first internal latch and a second external latch which are coaxial and connected to each other and the ratchet, called a combined ratchet, comprises a first internal ratchet and a second external ratchet which are coaxial and connected to each other and in that the first internal latch and the first internal ratchet cooperate in a first internal plane following one of the control actions and the second external latch and the second external ratchet cooperate in a second external plane following the other of the control actions, the two planes being parallel to each other.

[0016] It is the combination and the particular sequence in different planes of the parts of the combined latch and the combined pawl which cooperate successively which make it possible to achieve the object of the invention, in a way which is both simple to execute and unexpected.

[0017] The internal and external pawls and latches move in parallel planes, which makes it possible to optimize the space requirement of the lock arrangement by at least partially superimposing the internal and external parts of the combined pawl and the combined latch.

[0018] The doubling of the latch and the pawl in fact provides additional security thanks to the fact that the failure of one of the parts of the combined latch or the combined pawl is not sufficient to cause the latch to unlock and an untimely release of the strike plate.

[0019] The lock arrangement according to the invention may comprise one or more of the following features.

[0020] In another preferred embodiment of the invention, the combined pawl laterally comprises a stepped profile delimiting at least first and second reliefs cooperating with the combined latch respectively in the initial and intermediate configurations.

[0021] In another preferred embodiment of the invention, one of the reliefs is carried by the internal pawl and the other of the reliefs is carried by the external pawl.

[0022] In another preferred embodiment of the invention, the first relief comprises a locking lug which cooperates with a complementary locking notch formed in the combined latch to immobilize the assembly formed by the combined pawl and the combined latch in the initial configuration.

[0023] In another preferred embodiment of the invention, the combined latch has a fork-shaped lateral profile with at least three teeth successively delimiting the locking notch and the striker retaining notch.

[0024] In another preferred embodiment of the invention, the second relief comprises a surface capable of serving as a main stop for a contact surface of the combined latch in the intermediate configuration.

[0025] In another preferred embodiment of the invention, the stepped profile comprises a surface capable of serving as a temporary stop for a contact surface of the combined latch during the transition from the initial configuration to the intermediate configuration.

[0026] In another preferred embodiment of the invention, each contact surface of the combined latch extends over one of the end faces of the fork teeth.

[0027] In another preferred embodiment of the invention, the combined ratchet, having an elongated shape, comprises in the longitudinal direction a proximal end portion pivotally mounted around an articulation axis, an intermediate portion and a distal end portion coupled to the actuator.

[0028] In another preferred embodiment of the invention, the inner and outer pawls overlap only in the proximal end portion such that only one of the outer or inner pawls comprises the intermediate portion and the distal portion.

[0029] In another preferred embodiment of the invention, the combined pawl and the combined latch are pivotally mounted independently of each other and are resiliently biased by resilient means in opposite pivoting directions.

[0030] In another preferred embodiment of the invention, the arrangement comprises force transmission means between the latch and the pawl capable of actively pivoting the pawl into the locking position when the latch is brought into the engagement position with the striker.

[0031] In another preferred embodiment of the invention, the force transmission means comprise a contact surface of the latch and a contact surface of the pawl, said contact surfaces being able to slide on each other when the latch pivots towards its position of engagement with the striker.

[0032] The invention also relates to a motor vehicle according to the invention comprising a lock arrangement and an actuator which is electrically motorized.

[0033] The invention will be better understood and its advantages will appear better, on reading the detailed description which follows, of embodiments shown as non-limiting examples. The description refers to the appended drawings in which:

[0042] A lock arrangement for a motor vehicle hood according to the invention is shown in Figures 1 to 8. In the remainder of the description, the lock arrangement will be designated by the general reference 10.

[0043] As illustrated in [Fig.l], the arrangement 10 is configured to cooperate with a latch 100 fixed to the inside of the hood of the motor vehicle (not shown in the figures). For this purpose, the arrangement 10 comprises a latching mechanism 14 capable of cooperating with the latch 100 of the hood.

[0044] Preferably, as illustrated in the figures, the lock arrangement 10 further comprises a plate 12 serving as a support for the latching mechanism 14 and intended to be fixed to the vehicle. This plate 12 is for example made from a metal sheet, by cutting and / or folding said sheet.

[0045] As illustrated in [Fig.l], the plate 12 comprises for example a plurality of fixing lugs 12A for elastic means such as springs of the latching mechanism 14 (not shown) and a plurality of fixing holes 12B to the bodywork.

[0046] According to the invention and as illustrated in detail in particular in Figures 1 to 3, the lock arrangement 10 comprises a rotary latch 16 comprising a notch 18 capable of cooperating with the latch 100 of the hood. The latch 100 is for example in the form of a hook closed in the manner of a ring. The hook has for example a rectangular or square shape and the notch 18 of the latch 16 has a general hook shape to hold the latch 100.

[0047] In the example illustrated in the figures, the latch 16 is pivotally mounted about an axis XI on the plate 12. This axis XI formed by a journal 26 ([Fig.2]) can be fixed by screwing, welding and / or pressing on an orifice 12C made in the plate 12 ([Fig.2]). For this purpose, the latch 16 comprises a hole 48 for the insertion of the journal 26 ([Fig.4]).

[0048] Furthermore, preferably, as illustrated in [Fig.2], the plate 12 may also have a notch 12D in the shape of a fish mouth open towards the outside or in the shape of a U, intended to receive the striker 100 with a view to guiding it towards the notch 18 of the latch 16.

[0049] The lock arrangement 10 further comprises a locking pawl 22. This locking pawl 22 is arranged to cooperate with the latch 16 between at least an initial configuration of locking the latch 16 in total engagement of the strike plate 100 and a final configuration of unlocking the latch 16 in total release of the strike plate 100.

[0050] Preferably, the pawl 22 and the latch 16 are mounted to pivot independently of each other and are elastically stressed by elastic means in opposite pivoting directions.

[0051] In this example illustrated in [Fig.l], the pawl 22 is elastically returned in the counterclockwise rotation direction S2. For this purpose, the pawl 22 comprises tabs 28 for fixing the elastic means. Furthermore, in the example illustrated in [Fig.l], the latch 16 is elastically returned in the clockwise rotation direction SI. For example, the latch 16 is pushed using an ejection spring which makes it possible to orient the latch 16 in the ejection position of the striker 100. For this purpose, as illustrated in [Fig.4], the latch 16 comprises a fixing tab 17 of an elastic means forming for example the ejection spring.

[0052] According to the invention, the latch 16 is produced in the form of a double latch and comprises a first internal latch 161 and a second external latch 16E and the pawl 22 comprises a first internal pawl 221 and a second external pawl 22E. In the remainder of the description, the pawl 22 and the latch 16 will be designated by combined pawl 22 and combined latch 16 to differentiate them from the internal 161, 221 and external 16E, 22E split parts.

[0053] The transition from the initial configuration to the final configuration is carried out following at least one action of controlling the movement of the combined pawl 22, carried out for example by an actuating means or actuator. For example, the actuator comprises an actuating element drivingly coupled to the combined pawl 22 to pivot the combined pawl 22 from the initial configuration to the final configuration.

[0054] In particular, the actuator coupled to the combined pawl 22 makes it possible to selectively pivot the combined pawl 22 from the initial configuration to the intermediate configuration following a first control action and from the intermediate configuration to the unlocking configuration following a second control action.

[0055] For example, the actuator comprises a traction cable, preferably movable in a sheath and the actuator element is formed by an end piece of the traction cable, coupled to the pawl 22. In this case, the displacement action is a pulling action of the pawl 22. For example, the actuator element is in the form of a guide pin cooperating inside a groove 24 provided on the combined pawl 22 and illustrated in detail in [Fig.5].

[0056] The traction of the actuator causes the combined pawl 22 to move in the clockwise direction SI against the elastic stress exerted by the action of a return spring of the pawl 22 ([Fig.l]).

[0057] Preferably, the combined locking pawl 22 and the latch 16 cooperate together from the initial configuration to the final configuration via an intermediate locking configuration of the combined latch 16 in partial engagement of the strike plate 100. This thus makes it possible to unlock the lock arrangement 10 in two stages selectively from the initial locking configuration to an intermediate locking configuration on the one hand and then from the intermediate configuration to the final unlocking configuration on the other hand.

[0058] Preferably, the actuator element is arranged to selectively pivot the combined pawl 22 from the initial configuration to the intermediate configuration following a first cable pull and from the intermediate configuration to the final configuration following a second cable pull action. In other words, the actuator makes it possible to sequentially control the movement of the combined pawl 22 from one configuration to the other by the first and second cable pull actions. In the example described, the actuator is electrically motorized.

[0059] Furthermore, as illustrated in [Fig.2], the plate 12 further comprises a support lug 12E provided with a sheath stopper arranged to block the sheath surrounding the traction cable.

[0060] According to the invention, the first internal latch 161 and the second external latch 16E are coaxial and connected to each other, as illustrated in [Fig. 4] to form the combined latch 16. According to the invention, the first internal pawl 221 and the second external pawl 22E are also coaxial and connected to each other as illustrated in [Fig. 5] to form the combined pawl 22. Preferably, the internal 161 and external 16E latches are connected about the axis XI, for example, by one of the pins 26 which extends through the holes 481, 48E. Furthermore, Preferably, the pawls 221 and 22E are connected about the axis X2, for example, by one of the pins 26 which extends through the holes 251 and 25E.

[0061] Furthermore, in the example described, the internal 161 and external 16E latches are mounted fixed relative to each other, for example at the level of a fixing eyelet 45 comprising mounting holes 451 and 45E respectively of the internal 161 and external 16E latches. Preferably, the internal 221 and external 22E pawls are mounted pivoting relatively to each other around the axis X2.

[0062] More particularly, the first internal latch 161 and the first internal pawl 221 cooperate in a first internal plane PI following one of the control actions and the second external latch 16E and the second external pawl 22E cooperate in a second external plane PE following the other of the control actions, the two planes PI and PE being parallel to each other.

[0063] Preferably, as illustrated in [Fig.5], the combined pawl 22 laterally comprises a stepped profile 30 delimiting at least first 32 and second 34 reliefs cooperating with the combined latch 16 respectively in the initial and intermediate configurations.

[0064] As illustrated in [Fig.5], one of the reliefs 32 is carried by the internal pawl 221 and the other of the reliefs 34 is carried by the external pawl 22E.

[0065] In the preferred embodiment of the invention, the first relief 32 comprises a locking lug which cooperates with a complementary locking notch 20 formed in the combined latch 16 to immobilize the assembly formed by the combined pawl 22 and the combined latch 16 in the initial configuration.

[0066] Preferably, the second relief 34 comprises a surface capable of serving as a main stop for a contact surface 44 of the combined latch 16 in the intermediate configuration.

[0067] In the example described, the stepped profile 30 of the combined pawl 22 comprises a third relief 36 cooperating with the combined latch 16 to provide a temporary stop during the transition from the initial configuration to the intermediate configuration. This makes it possible to maintain the combined latch 16 in a transient locking position during the transition from the initial configuration to the intermediate configuration.

[0068] Preferably and as illustrated in Figures 4 and 5, the third relief 36 comprises a surface which is capable of serving as a temporary stop with a contact surface 46 of the combined latch 16.

[0069] Thus, as can be seen in [Fig. 4], the combined latch 16 has a lateral profile 40 in the form of a fork with at least three teeth 42 successively delimiting the locking notch 20 and the notch 18 for retaining the strike plate 100.

[0070] Preferably, each contact surface 44, 46 of the combined latch 16 extends over one of the end faces of the teeth 42 of the fork 40.

[0071] Preferably, the combined ratchet 22 having an elongated shape, it comprises in the longitudinal direction a proximal end portion 22A pivotally mounted around the articulation axis XI, an intermediate portion 22B and a distal end portion 22C coupled to the actuator.

[0072] In the example illustrated in [Fig.5], the internal 221 and external 22E pawls only overlap in the proximal end portion 22A such that only one of the external 22E or internal 221 pawls comprises the intermediate portion 22B and the distal portion 22C of the combined pawl 22.

[0073] In the example illustrated in [Fig. 4], the internal 161 and external 16E latches are substantially superimposed over their entire surface. The internal latch 161 has a central tooth 421 which projects relative to the corresponding central tooth 42E of the external latch 16E so as to define the contact surface 46 of the combined latch 16. In addition, the external latch 16E has a lateral tooth 42E which projects relative to the corresponding lateral tooth 421 of the internal latch 161 so as to define the contact surface 44 of the combined latch 16.

[0074] Preferably, the arrangement 10 comprises force transmission means between the latch 16 and the pawl 22 capable of actively pivoting the pawl 22 into the locking position when the latch 16 is brought into the engagement position with the striker 100.

[0075] For example, the force transmission means comprise a contact surface 54 of the latch 16 and a contact surface 52 of the pawl 22, said contact surfaces 52, 54 being able to slide over each other when the latch 16 pivots towards its position of engagement with the striker 100.

[0076] In this example, the contact surface 54 is carried by the external latch 16E, for example in the lower extension of the contact surface 44. In order to cooperate in the plane PE, the contact surface 52 is carried by the external pawl 22E, for example in the upper extension of the contact surface 34.

[0077] The main operational aspects of the invention will now be described with reference to Figures 1 to 8.

[0078] Initially, the lock arrangement 10 is in the initial configuration illustrated in [Fig.l]. In this initial configuration, the combined latch 16 is in full engagement with the striker 100 of the hood of the motor vehicle and cooperates with the lug 32 of the combined pawl 22 by its notch 20.

[0079] The user then wishes to open the hood of the motor vehicle. During a first step 6A ([Fig.6]), he controls the actuator to perform a first action of moving the combined pawl 22 by pulling the cable. The pawl 22 is then also pivoted by the pulling effect of the cable against the elastic stress in the clockwise direction SLA at the end of this step 6B, the first relief 32 of the combined pawl 22 is then disengaged from the notch 20 of the combined latch 16 but has not yet engaged its second relief 34 with the surface 44 of the combined latch 16.

[0080] As can be seen in [Fig. 6], in step 6C, the combined latch 16, being disengaged from the combined pawl 22, can pivot freely in the clockwise release direction SI by elastic return. Furthermore, during this pivoting, the combined latch 16 cooperates with its contact surface 46 with the third relief 36 to produce a temporary stop ([Fig. 6]; 6C).

[0081] As can be seen in [Fig. 6], in step 6D, the traction of the actuator element is released. The combined pawl 22 having pivoted against its elastic bias, pivots in the opposite direction S2 to return to its initial rest position by elastic return. The combined pawl 22 and the combined latch 16 are then in the intermediate configuration of partial disengagement of the striker 100 in which the second relief 34 of the pawl 22 cooperates with the second stop surface 44 of the combined latch 16.

[0082] During a second step 7A ([Fig.7]), the user controls the actuator to perform a second action of moving the element by pulling the cable. The actuator element is then driven into movement and causes the combined pawl 22 to pivot in the clockwise direction SI ([Fig.7]; 7B, [Fig.7]; 7C). The combined latch 16 is then driven into pivoting until the striker 100 is released from the notch 18. The combined latch 16 and the combined pawl 22 are then in their final unlocking configuration ([Fig.7]; 7D).

[0083] Also shown in [Fig. 8] are steps A to D of locking the lock arrangement 10 of the hood of the motor vehicle. Initially, the lock arrangement 10 is in the final configuration illustrated by [Fig. 7], in step 7D.

[0084] Initially, in this configuration, the latch 16 is in total release from the striker 100. The combined latch 16 is retained in this release position for example by the elastic stress exerted by the ejection spring for example. When the hood is open, the latch 16 and its notch 18 are oriented so as to be able to receive the striker 100.

[0085] Then during a step 8A, the user of the motor vehicle applies a force to the hood of the vehicle so that the latch 100 transmits this force to the combined latch 16.

[0086] This has the effect of pivoting the combined latch 16 relative to the combined pawl 22 by guiding their respective support portions until the latch 16 crosses the second relief 34 of the pawl 22 ([Fig.8]; 8B).

[0087] Then, during step 8C, the continuation of the force exerted by the user on the hood of the motor vehicle causes the latch to continue pivoting. combined 16 which leads to engaging the lug 32 inside the notch 20 of the combined latch 16. At the end of step 8D, the lock arrangement 10 is in the initial locking configuration illustrated by [Fig.l].

[0088] Of course, the invention is not limited to the embodiments previously described. Other embodiments within the reach of those skilled in the art may also be envisaged without departing from the scope of the invention defined by the claims below. In particular, in the present description, the elastic means described comprise tension springs but alternatively, the elastic means may comprise torsion springs or any other elastic means known in the prior art.
