Description

Title of the invention: vehicle comprising a lifting platform

[0001] The technical context of the present invention is that of vehicles comprising a lifting platform, and more particularly that of stabilization systems for such vehicles in order to prevent said vehicle from tipping over when using the lifting platform.

[0002] In the state of the art, motor vehicles are known, in particular those of the utility vehicle type, equipped with a lifting platform allowing an operator to work at height. For this purpose, the lifting platform comprises a working platform mounted at the end of a poly-articulated and extendable arm which can be deployed and oriented according to a plurality of positions in order to bring the working platform to any height and any orientation with respect to the motor vehicle. In this case, the lifting platform is integral with the motor vehicle. For example, it is placed at the rear of the motor vehicle or extends from a roof or a floor of the motor vehicle, behind a passenger compartment of the motor vehicle.

[0003] We also know autonomous or remotely controlled vehicles comprising a lifting platform similar to that described above. In this case, the autonomous vehicles comprise a base secured to mobile wheels in order to be able to move.

[0004] In either case, when using the lifting platform, the center of gravity of the vehicle - automobile or autonomous - moves with the movement of the work platform. Such a movement can lead to tipping of the vehicle.

[0005] To ensure the stability of known vehicles equipped with a lifting platform, the use and integration of stabilizers on each side of said vehicles is known. These stabilizers comprise pads which are deployed towards the ground. Such known pads suffer from a design choice resulting from contradictory constraints. Indeed, according to a first constraint, such pads, when they are supported against the ground, should be located at a lateral distance from the lateral edges of the vehicle in order to improve the stability of the vehicle and reduce the risks of tipping when the working platform of the lifting platform is offset laterally relative to said vehicle.Conversely, according to a second constraint, such soles, when retracted, cannot have too great an overhang in relation to the lateral sides of the vehicle in order to limit its size and to authorize, for example in the case of a motor vehicle, its circulation on a road.

[0006] Furthermore, in the case of a lifting platform fitted to a motor vehicle and mounted in a storage space located at the rear of the passenger compartment, the stabilizers then pass through the floor of these motor vehicles, leading to an increase in complexity of said motor vehicles, particularly in comparison with lifting platforms mounted at the rear of a motor vehicle.

[0007] The object of the present invention is to propose a new vehicle equipped with a nacelle in order to respond at least to a large extent to the preceding problems and to further lead to other advantages.

[0008] Another object of the invention is to improve the stabilization of such a vehicle during deployment and use of the lifting platform.

[0009] Another object of the invention is to reduce the manufacturing costs of such a vehicle.

[0010] According to a first aspect of the invention, at least one of the aforementioned objectives is achieved with a vehicle comprising a lifting cradle, a working platform of which is mounted at a free end of an articulated arm secured to the vehicle, and a device for stabilizing the vehicle, the stabilizing device being configured to be able to be deployed on at least one lateral side of the vehicle in order to form a support against the ground at a distance from the vehicle.

[0011] In the vehicle according to the invention, the stabilization device comprises at least one articulated stabilization system, each articulated stabilization system comprising:

[0012] - a stabilizer assembly comprising a first retractable arm and a second retractable arm;

[0013] - an actuation system configured to control the stabilizer assembly in order to configuring the first retractable arm and the second retractable arm in a first configuration in which said first arm and said second arm are extended and in a second configuration in which said first arm and said second arm are retracted;

[0014] - a telescopic arm supporting at its free end the stabilizer assembly, the telescopic arm being configured to assume a retracted configuration in which the free end is lowered towards and near the ground.

[0015] In the context of the present invention, the vehicle is of the type of a motorized and mobile vehicle, the vehicle comprising at least two wheels, preferably three or even four, and even six.

[0016] According to a first variant embodiment, the vehicle is of the motor vehicle type, that is to say comprising a passenger compartment and a driving position in order to allow a driver to pilot said motor vehicle. This first variant embodiment thus groups together the lifting platforms on a carrier. In this first variant embodiment, the motor vehicle is preferably of the van or van type. More generally, the motor vehicle is of the utility vehicle type, that is to say equipped with a large storage capacity, in a storage space located at the rear of the passenger compartment.

[0017] According to a second embodiment variant, the vehicle is of the type of a semi-autonomous vehicle piloted remotely by an operator. Such a semi-autonomous vehicle does not have a passenger compartment. This second embodiment variant includes in particular scissor lifts, telescopic boom lifts, vertical mast lifts, spider lifts. In this case, such a vehicle has a base to which the lifting platform is connected.

[0018] In the context of the present invention, the lifting platform is configured to allow an operator to work at height relative to the vehicle. The lifting platform thus comprises a work platform mounted at the end of a poly-articulated and extendable arm configured to be able to deploy and orient itself according to a plurality of positions. The lifting platform - and more particularly its poly-articulated and extendable arm - is secured to the vehicle. In the case of a motor vehicle for example, the lifting platform is placed at the rear of the motor vehicle or extends from a roof or a floor of the motor vehicle, behind a passenger compartment of the motor vehicle.

[0019] In the context of the present invention, the stabilization device is configured to provide additional support for the vehicle against the ground. The stabilization device more particularly provides support against the ground and with a non-zero offset relative to the motor vehicle or the base of the vehicle to which the lifting platform is attached. In the context of the invention, the stabilization device comprises one or more articulated stabilization systems. In the case where the stabilization device comprises several articulated stabilization systems, the articulated stabilization systems are distributed over the motor vehicle so as to provide support against the ground at the periphery of said vehicle and preferably relative to different lateral sides, in order to optimize the stabilization of the vehicle when the lifting platform is used.Preferably, each stabilization system is associated with a distinct lateral side of the vehicle. In the context of the invention, the articulated stabilization system(s) are said to be articulated because they have one or more articulation in order to be able to store the stabilization device under or in the vehicle, in a configuration in which the articulated stabilization system(s) do not cooperate with the ground, and a support configuration in which the articulated stabilization system(s) cooperate with the ground to provide additional support for the vehicle according to the invention.

[0020] In the context of the present invention, the stabilizer assembly forms a stabilization platform which is configured to allow support against the ground on which the vehicle according to the invention rests. The stabilizer assembly comprises the first retractable arm and the second retractable arm. Each retractable arm can thus be configured in a first configuration in which the articulated stabilization system(s) do not cooperate with the ground, and in a second support configuration in which the articulated stabilization system(s) cooperate with the ground to provide additional support for the vehicle according to the invention. In the first configuration, the retractable arms are folded and are located at a distance from the ground, so that there is no direct connection - i.e., no support - between the stabilizing assembly and the ground on which the vehicle according to the invention rests. On the other hand, in the second configuration, the retractable arms are unfolded at a distance from the motor vehicle and placed in abutment against the ground, so that there is now a direct connection - i.e., a support - between the stabilizing assembly and the ground on which the vehicle according to the invention rests.

[0021] In the context of the present invention, the retractable arms are articulated arms that can be unfolded or folded in order to be configured in the first configuration or in the second configuration. Each retractable arm allows the corresponding articulated stabilization system to be unfolded or folded with respect to a lateral side of the vehicle, so as to be able to extend beyond or respectively fold within a footprint of the vehicle, the footprint being determined by the space between each peripheral side of the vehicle.

[0022] In the context of the present invention, the telescopic arm is configured to generate a vertical or substantially vertical translation of the corresponding stabilizer assembly. Generally, the telescopic arm is configured to move the corresponding stabilizer assembly closer to or further away from the ground on which the vehicle according to the invention rests. When the telescopic arm is in its retracted configuration, then the stabilizer assembly is placed close to the ground, so as to be able to establish a bearing against said ground by configuring the corresponding retractable arms in their unfolded configuration. On the other hand, when the telescopic arm is raised in a retracted configuration, then the corresponding stabilizer assembly is placed at a distance from the ground, so as to be able to configure the corresponding retractable arms in their folded configuration.

[0023] Thus, the vehicle according to the invention makes it possible to propose a more efficient stabilization system than those known until now. Indeed, the possibility of being able to unfold retractable arms makes it possible to increase the ground clearance. Furthermore, in the case of a motor vehicle, it is not necessary to modify the lateral sides of the motor vehicle. The stabilization device makes it possible to deploy or fold the articulated stabilization system without requiring major modifications to the motor vehicle, thus making it possible to equip such motor vehicles with a lifting platform at lower costs.

[0024] The vehicle according to the first aspect of the invention advantageously comprises at least one of the improvements below, the technical characteristics forming these improvements being able to be taken alone or in combination:

[0025] - the telescopic arm comprises (i) a fixed outer sheath, (ii) a sheath inner sheath housed in the fixed outer sheath, the stabilizer assembly being fixed to a lower end of the inner sheath, said lower end forming the free end of the telescopic arm, and (iii) a linear actuator configured to move the inner sheath in translation in and along the outer sheath. Advantageously, the inner sheath is guided in translation in the outer sheath, the outer sheath comprising means for guiding the inner sheath in translation. In the case of a vehicle of the motor vehicle type, according to a preferred embodiment, the telescopic arm is located in a storage space of the motor vehicle, at the rear of a driving position of the motor vehicle. preferably, the telescopic arm is associated with a frame of the poly-articulated and extendable arm of the lifting platform;

[0026] - advantageously, the linear actuator is of the hydraulic cylinder type. A cylindrical tube of the hydraulic cylinder is secured to the vehicle and a piston of said hydraulic cylinder is secured to the stabilizer assembly;

[0027] - the telescopic arm comprises an angular adaptation member of the stabilizing assembly lizer, the angular adaptation member being located in an intermediate position between said stabilizer assembly and the free end of the telescopic arm. In the context of the present invention, the angular adaptation member makes it possible to make the stabilizer assembly and the ground on which the vehicle according to the invention rests parallel. By way of non-limiting example, the adaptation member comprises a ball joint or a pivot connecting the lower end of the inner sleeve and the stabilizer assembly;

[0028] - the outer sheath of the telescopic arm is integral with the vehicle. And more particularly of a chassis or floor of the vehicle;

[0029] - the telescopic arm extends through an opening provided on a floor of the vehicle, the stabilizer assembly being located below said floor. This advantageous configuration makes it possible to optimize the compactness of the stabilization device. Indeed, the lower end of the inner sleeve is then located opposite the floor with respect to the outer sleeve of the hydraulic cylinder, so that the stabilizer assembly of the corresponding articulated stabilization system is ultimately located under the vehicle. Thus, when the articulated stabilization system is folded, then each corresponding stabilizer assembly is placed against or near a lower face of the vehicle floor. Conversely, when the articulated stabilization system is deployed and unfolded so as to provide support against the ground on which the vehicle rests, then each corresponding stabilizer assembly is placed at a distance from the underside of the floor;

[0030] - in particular, when the telescopic arm is configured in its configuration retracted, then the stabilizer assembly is located away from the floor, close to the ground on which the vehicle rests. Conversely, when the telescopic arm is configured in a storage configuration, then the stabilizer assembly is located close to the floor, away from the ground on which the vehicle rests;

[0031] - the stabilizer assembly comprises a crosspiece connected to the free end of the T arm telescopic, the first retractable arm being integral with a first end of the cross member via a connection allowing its folded configuration and its unfolded configuration, the second retractable arm being integral with a second end of the cross member opposite the first end, via a connection allowing its folded configuration and its unfolded configuration. Each retractable arm comprises at least one support sole against the ground. The support sole is fixed integrally to the retractable arm. More particularly, the support sole is connected to the retractable arm via an angular adaptation member. By way of non-limiting example, the angular adaptation member comprises a ball joint or a pivot connecting the retractable arm and the support sole. The support sole has a shape configured to maximize its ground grip and stabilize the vehicle according to the invention, for example of conical shape;

[0032] - the first retractable arm and the second retractable arm are integral respectively tively of the first end and the second end of the crosspiece by means of a ball joint or pivot connection. This configuration thus makes it possible to fold or unfold each retractable arm relative to the crosspiece;

[0033] - the actuation system comprises, for each retractable arm, (i) a first connecting rod, a first end of which is connected to the crosspiece through a connection allowing its rotation, (ii) a second connecting rod, a first end of which is connected to a second end of the first connecting rod and a second end of which is connected to the corresponding retractable arm, the first connecting rod and the second connecting rod being connected to each other through a connection allowing their rotation, and the second end of the second connecting rod being movable in rotation with respect to the corresponding retractable arm, (iii) an actuator configured to generate a force on the first connecting rod and the second connecting rod, so as to be able to fold or unfold the corresponding retractable arm. In particular, when the actuator pushes on the first connecting rod and on the second connecting rod, then the corresponding retractable arm is unfolded.Conversely, when the actuator pulls on the first connecting rod and on the second connecting rod, then the corresponding retractable arm is folded towards the crosspiece. The actuator is advantageously of the type of an electric or hydraulic cylinder; .

[0034] - the vehicle comprises a first articulated stabilization system located on a first lateral side of the vehicle and a second articulated stabilization system located on a second lateral side of the vehicle, opposite the first lateral side;

[0035] - the vehicle is of the type of a motor vehicle or a semi-autonomous vehicle.

[0036] Various embodiments of the invention are provided, integrating according to all of their possible combinations the different optional characteristics set out here.

[0037] Other characteristics and advantages of the invention will become apparent from the following description on the one hand, and from several examples of embodiment given for informational and non-limiting purposes with reference to the appended schematic drawings on the other hand, in which:

[0045] Of course, 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 imagined 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 prior art.

[0046] In particular, all the variants and all the embodiments described can be combined with each other if nothing prevents this combination from a technical point of view.

[0047] In the figures, the elements common to several figures retain the same reference.

[0048] With reference to FIGURES 1 to 3, the invention relates to a vehicle 1, and preferably to a motor vehicle 1 of the utility type as illustrated in the FIGURES 1 to 3. However, the invention addresses a vehicle 1 in its most general sense of the term, that is to say a machine having the capacity to move, preferably in a motorized manner. In FIGURES 1 to 3, for the sake of clarity, the invention is illustrated in its implementation on a motor vehicle 1.

[0049] Such a utility motor vehicle 1 comprises a passenger compartment housing a driving position 101, at the front of the motor vehicle 1, and a storage space 102 located behind the driving position 101. The storage space 102 can be open or closed, as in the illustrated embodiment.

[0050] The vehicle 1 according to the invention comprises a lifting platform 11 comprising a poly-articulated and extendable arm 112 and a work platform 111 located at a free end of the poly-articulated and extendable arm 112. In the embodiment illustrated in the FIGURES, the platform is attached to the motor vehicle 1 by means of a pillar 110 housed in the storage space 102. The pillar 110 is fixed integrally to the floor 103 of the motor vehicle 1, and even to its chassis for greater rigidity. The pillar 110 passes through 133 a roof of the storage space 102 in order to arrange the poly-articulated and extendable arm 112 outside the storage space 102. The poly-articulated and extendable arm 112 thus extends above the motor vehicle 1 in order to allow movement of the work platform 111 in multiple directions and orientations with respect to said motor vehicle 1.

[0051] However, in the context of the present invention, the lifting platform 11 may be associated with the motor vehicle 1 in any arrangement. In particular, in another configuration not shown in the FIGURES, the lifting platform 11 may be mounted on the motor vehicle 1 at the rear and outside the storage space 102, near a rear bumper.

[0052] In order to prevent the lifting platform 11 from shifting, when it is in use and the work platform 111 is deployed at a distance from the motor vehicle 1, the vehicle 1 according to the invention comprises a stabilization device 12.

[0053] The stabilization device 12 comprises at least one articulated stabilization system 13. In the embodiment illustrated in FIGURES 1 to 3, the stabilization device 12 of the vehicle 1 according to the invention comprises a single articulated stabilization system 13 which is arranged along a right side of the motor vehicle 1. This configuration thus makes it possible to reinforce the stability of the motor vehicle 1 when the lifting platform 11 is deployed so that the work platform 111 is arranged high up and to the right of the motor vehicle 1. Such a configuration thus makes it possible to prevent the motor vehicle 1 from tipping over in this case of use.

[0054] However, in the context of the invention, the stabilization device 12 may comprise several articulated stabilization systems 13. In this case, it is advantageous for each articulated stabilization system 13 to be located on a peripheral side spherical distinct from vehicle 1. For example:

[0055] - a first articulated stabilization system 13 is associated with a left side of the vehicle 1, so as to be able to be unfolded remotely from a left side of the vehicle 1 according to the invention; and / or

[0056] - a second articulated stabilization system 13 is associated with a right side of the vehicle 1, so as to be able to be unfolded remotely from a right side of the vehicle 1 according to the invention.

[0057] In the case of a vehicle 1 of the semi-autonomous type, it may be advantageous to supplement the previous stabilization device 12 with at least one other articulated stabilization system 13 associated with another side of the vehicle 1, front or rear for example, so as to be able to be unfolded remotely from the corresponding side of the vehicle 1 according to the invention.

[0058] The stabilization systems are all independent of each other. In addition, they can be selectively controlled so as to control the unfolding or folding of each stabilization system selectively.

[0059] With reference to FIGURES 4 to 7, and according to the invention, each articulated stabilization system 13 forming the stabilization device 12 comprises:

[0060] - a stabilizer assembly 130 comprising a first retractable arm 131 and a second retractable arm 132;

[0061] - an actuation system configured to control the stabilizer assembly 130 in order to to configure the first retractable arm 131 and the second retractable arm 132 in a first configuration in which said first arm and said second arm are unfolded and in a second configuration in which said first arm and said second arm are folded;

[0062] - a telescopic arm supporting at its free end 1341 the stabilizer assembly 130, the telescopic arm being configured to assume a retracted configuration in which the free end 1341 is lowered towards and near the ground.

[0063] As visible in FIGURES 4 and 7, when the stabilizing device 12 is configured in its unfolded configuration, the first retractable arm 131 and the second retractable arm 132 are located at a distance from each other, so as to form a sufficient wheelbase to stabilize the motor vehicle 1. In particular, the stabilizing assembly 130 comprises a cross member 133 connected to the free end 1341 of the telescopic arm.

[0064] The first retractable arm 131 is secured to a first end of the crosspiece 133 by means of a first pivot connection 1311 allowing its folded configuration and its unfolded configuration; and the second retractable arm 132 is secured to a second end of the crosspiece 133 opposite the first end, by means of a second pivot connection 1321 allowing its confi- folded configuration and its unfolded configuration.

[0065] Thus, as visible in [Fig. 6], when the articulated stabilization system 13 is configured in its folded configuration, the second retractable arm 132 is first folded against the cross member 133, then the first retractable arm 131 is folded against the second retractable arm 132. For this purpose, the first retractable arm 131 has a general L shape, the first retractable arm 131 having a general bent conformation so as to be able to fold adjacent to the second retractable arm. Conversely, the second retractable arm 132 has a general rectilinear conformation.

[0066] The first retractable arm 131 and the second retractable arm 132 comprise soles making it possible to create a connection bearing on the ground when the stabilization device 12 is configured in its deployed configuration. Each sole 134 takes the form of a cone fixed integrally to a face of the retractable arms 131, 132 located opposite the ground. The first retractable arm 131 comprises a first sole 134 located near its first pivot connection 1311 and a second sole 134 located at a distance from said first pivot connection 1311, at a free end of said first retractable arm 131. Similarly, the second retractable arm 132 comprises a first sole 134 located near its second pivot connection 1321 and a second sole 134 located at a distance from said second pivot connection 1321, at a free end of said second retractable arm 132.

[0067] In order to configure the first retractable arm 131 and the second retractable arm 132 either in their unfolded configuration or in their folded configuration, the actuation system advantageously comprises, for each retractable arm 131, 132:

[0068] - a first connecting rod 135, a first end of which is connected to the crosspiece 133 at through a connection allowing its rotation,

[0069] - a second connecting rod 136 of which a first end is linked to a second end of the first connecting rod 135 and a second end of which is connected to the corresponding retractable arm 131, 132, the first connecting rod 135 and the second connecting rod 136 being connected to each other through a connection allowing their rotation, and the second end of the second connecting rod 136 being movable in rotation with respect to the corresponding retractable arm 131, 132,

[0070] - an actuator 137 configured to generate a force on the first connecting rod 135 and the second connecting rod 136, so as to be able to fold or unfold the corresponding retractable arm 131, 132.

[0071] In particular, when the actuator 137 pushes on the first connecting rod 135 and on the second connecting rod 136, then the corresponding retractable arm 131, 132 is unfolded. Conversely, when the actuator 137 pulls on the first connecting rod 135 and on the second connecting rod 136, then the corresponding retractable arm 131, 132 is folded towards the crosspiece 133.

[0072] The actuator 137 is advantageously of the electric jack type.

[0073] The actuators 137 are placed in opposition to one another. The actuators 137 are furthermore preferably controlled synchronously, so as to respectively allow unfolding or folding of the first retractable arm 131 and of the second retractable arm 132 simultaneously: either the two retractable arms 131, 132 are simultaneously configured in their unfolded configuration, or the two retractable arms 131, 132 are simultaneously configured in their folded configuration.

[0074] As visible in FIGURES 4 and 5, the telescopic arm makes it possible to move the stabilizer assembly 130 vertically relative to the ground and the floor 103 of the vehicle 1. According to a particularly advantageous embodiment and shown in the FIGURES, the telescopic arm comprises:

[0075] - a fixed outer sheath,

[0076] - an inner sheath housed in the fixed outer sheath, the stabilizing assembly 130 being fixed to a lower end of the inner sheath, said lower end forming the free end 1341 of the telescopic arm, and

[0077] - a linear actuator configured to move the inner sleeve in translation in and along the outer sheath.

[0078] The inner sheath is guided in translation in the outer sheath, the outer sheath comprising means for guiding the inner sheath in translation, not visible in FIGURES 4 and 5.

[0079] As visible in FIGURES 1 to 3, in the embodiment illustrated and according to which the vehicle 1 according to the invention is of the type of a utility motor vehicle 1, the telescopic arm is housed in the storage space of the motor vehicle 1. Preferably, the telescopic arm is associated with a pillar 110 of the poly-articulated and extendable arm 112 of the lifting platform 11 housed in the storage space 102 and fixed integrally to the floor 103 of the vehicle 1.

[0080] Preferably, the linear actuator of the telescopic arm is of the hydraulic cylinder type.

[0081] Furthermore, the telescopic arm comprises an angular adaptation member 138 of the stabilizer assembly 130, the angular adaptation member 138 being located in an intermediate position between said stabilizer assembly 130 and the free end 1341 of the telescopic arm. In the context of the present invention, the angular adaptation member 138 makes it possible to make the stabilizer assembly 130 parallel to the ground on which the vehicle 1 according to the invention rests, by allowing free rotation of the stabilizer assembly 130, for example under the simple effect of gravity.

[0082] In the embodiment illustrated in FIGURES 1 to 3, the adaptation member comprises a pivot connecting the lower end of the inner sleeve and the stabilizer assembly 130. Furthermore, in order to limit an angular movement of the stabilizer assembly 130 under the telescopic arm, the telescopic arm advantageously comprises an angular stop 139.

[0083] The telescopic arm extends through an opening 104 provided on a floor 103 of the vehicle 1, the stabilizer assembly 130 being located below said floor 103. The free end 1341 of the telescopic arm is then located under the floor 103 opposite, while the outer sheath remains in the storage space, above the floor 103. Thus, the stabilizer assembly 130 of the corresponding articulated stabilization system 13 is located under the vehicle 1:

[0084] - when the articulated stabilization system 13 is folded, then each sta assembly corresponding stabilizer 130 is placed against or near a lower face of the floor 103 of the vehicle 1; and

[0085] - when the articulated stabilization system 13 is deployed and unfolded so as to to provide support against the ground on which the vehicle 1 rests, then each corresponding stabilizer assembly 130 is placed at a distance from the lower face of the floor 103.

[0086] As visible in [Fig.l], when the telescopic arm is configured in a storage configuration, then the stabilizer assembly 130 is located near the floor 103, at a distance from the ground on which the vehicle 1 rests. Conversely, as visible in [Fig.2], when the telescopic arm is configured in its retracted configuration, then the stabilizer assembly 130 is located at a distance from the floor 103, near the ground on which the vehicle 1 rests. Finally, as visible in [Fig.3], the telescopic arm is configured in a configuration according to which the stabilization device 12 is lowered towards the ground, or even pressed against the ground, but the retractable arms 131, 132 are not yet deployed.This configuration may be an intermediate position of the stabilization device 12 during deployment, or even a stabilization position if there is insufficient space around the motor vehicle 1 for the complete deployment of the retractable arms 131, 132.

[0087] In summary, the invention relates to a vehicle 1 comprising a lifting platform 11 and a stabilization device 12 configured to be able to be deployed on at least one lateral side of the vehicle 1 in order to form a support against the ground at a distance from the vehicle 1. The stabilization device 12 comprises at least one articulated stabilization system 13, each articulated stabilization system 13 comprising being controlled by an actuation system in order to be able to configure a first retractable arm 131 and a second retractable arm 132 in a first configuration in which said first arm and said second arm are unfolded, and in a second configuration in which said first arm and said second arm are folded. The articulated stabilization system 13e is deployed towards the ground by means of a telescopic arm.

[0088] Of course, the invention is not limited to the examples which have just been described and numerous adjustments can be made to these examples without departing from the scope of the invention. In particular, the different characteristics, forms, variants and embodiments of the invention can be associated with each other in various combinations insofar as they are not incompatible or mutually exclusive. In particular, all the variants and embodiments described above can be combined with each other.
