This patent application claims priority from Italian patent application no. 102023000003852 filed on Mar. 3, 2023, the entire disclosure of which is incorporated herein by reference.
The present invention relates to a motor vehicle and a method for the reconfiguration of the motor vehicle.
As is known, motor vehicles comprise:
Passenger compartments of motor vehicles normally intended for road use have the so-called ‘two-seater’ configuration.
In this ‘two-seater’ configuration, the passenger compartment comprises a pair of front seats intended to be occupied by a driver and a passenger, respectively, and arranged side-by-side along a transversal direction of the motor vehicle orthogonal to a longitudinal direction defining a normal driving direction of the motor vehicle.
The steering wheel and set of pedals are located in front of the driver's seat and substantially at a front left or right corner of the motor vehicle.
With particular reference to sports cars, passenger compartments are known to have the so-called ‘single-seater’ configuration.
In this ‘single-seater’ configuration, the passenger compartment comprises a single front seat positioned centrally in front of the steering wheel and the set of pedals.
There is a need in the field for motor vehicles which allow easy and convenient reconfiguration between the above-mentioned ‘single-seater’ and ‘two-seater’ configurations.
EP-A-3712035 discloses a steering assembly for a motor vehicle, in which a steering wheel can be moved to multiple positions for manual operation, in both manufacturing and use contexts.
The object of the present invention is to provide a motor vehicle which allows the above-mentioned need to be met.
Said object is achieved by the present invention, insofar as it relates to a motor vehicle as defined in claim 1.
The present invention also relates to a method for the reconfiguration of the motor vehicle as defined in claim 10.
In order to better understand the present invention, a non-limiting preferred embodiment thereof will now be described by way of example with reference to the accompanying drawings, in which:
With reference to
It should be specified that, below in this description, expressions such as “above”, “below”, “in front of”, “behind” and the like are used with reference to the normal driving direction of the motor vehicle 1.
The motor vehicle 1 further comprises (
The motor vehicle 1 further comprises (
It is also possible to define:
The body 2 also comprises a pair of longitudinal, end door sills 23, 24, opposite each other. The door sills 23, 24 delimit the passenger compartment 3 and are adjacent to respective doors 8a, 8b when the doors 8a, 8b are in their closed positions.
In addition, the motor vehicle 1 comprises control members 10 which can be operated by the driver to set a forward trajectory of the motor vehicle 1 at a desired speed.
As is well known, the control members 10 comprise:
The set of pedals 12 comprises, in a nutshell and in a manner not described in detail as it is not necessary for the purpose of the present invention and only schematically illustrated in
If the engine 9 is an electric engine, the gearbox 20 and the clutch pedal are not present.
If the gearbox 20 is semi-automatic or automatic, the clutch pedal is not present.
The control members 10 are connected to the engine and wheels 6 and/or 7 through a drive-by-wire mode, thus producing a technology known in the industry as ‘drive by wire’.
The term ‘drive by wire’ in the present description is intended to mean that the steering mechanism 11 has no physical or mechanical connection to the wheels 6, 7.
Similarly, the accelerator pedal 17 has no physical or mechanical connection to the engine 9, and the brake pedal 17 has no mechanical connection to the braking system 21.
The passenger compartment 3 further comprises a front location 25 which defines a driver's seat.
The location 25 is only schematically shown in
The passenger compartment 3 of the motor vehicle 1 is selectively movable, in a manner not described in detail because it is not necessary for the understanding of the present invention, between:
In the ‘two-seater’ configuration, the first seat is beside the door sill 23, and the second seat is beside the door sill 24.
In addition, the first seat faces the steering mechanism 11 and the set of pedals 12 to allow the driver to operate the steering mechanism 11 and the set of pedals 12.
In the ‘single-seater’ configuration, the third seat is arranged in a central position between the door sills 23, 24 and faces the steering mechanism 11 and the set of pedals 12.
The steering mechanism 11, in turn, comprises (
The motor vehicle 1 also comprises a control unit 45 (
In particular, the control unit 45 is programmed to control the rotation of the wheels 6, 7 by an angle associated with the angle of rotation of the steering wheel 62 around the axis H and in the same direction of rotation.
In the case illustrated herein, the axis H is inclined with respect to the horizontal plane defined by the axes X, Y by an angle α (
The steering mechanism 11 also comprises a lever 65 that can be selectively moved between:
Advantageously, the steering mechanism 11 can be moved along the axis Y to allow the motor vehicle 1 to be moved between the first and the second configuration.
In this way, the steering mechanism 11 can be moved parallel to the axis Y between:
The steering mechanism 11 is adjacent to the door sill 23 when it is arranged in the first position (
A left-hand driving mode of the motor vehicle 1 is thus achieved.
In greater detail, the steering wheel 62 is in a central position between the door sills 23, 24, when the steering mechanism 12 is in the second position (
With reference to
The cross member 50 is arranged in front of the cross member 51.
The cross members 50, 51 extend over the full width of the motor vehicle 1 along the axis Y and comprise:
The cross members 50, 51, in turn, comprise:
In addition, the passenger compartment 3 comprises a connection assembly 30 (
The connection assembly 30, in turn, comprises:
The slide 76, in particular, is arranged in front of the slide 77.
The guides 52, 53 and the slides 76, 77 are arranged at a top face 54 of the support body 60.
The guides 52, 53 and the related slides 76, 77 are also arranged below the corresponding cross members 50, 51.
In particular, the guides 52, 53 are arranged within respective seats 95, 97 of corresponding cross members 50, 51.
The guides 52, 53 and the respective seats 95, 97 extend substantially to a width equal to half the width of the cross members 50, 51 and of the motor vehicle 1 along the axis Y, and comprise:
The axis I is parallel to the axis H.
With reference to
Each connection element 90 comprises, in particular (
The motor vehicle 1 further comprises a system for moving the set of pedals 12 parallel to the axis Y, which is not described in detail as it is not part of the present invention.
In a nutshell, the above-mentioned movement system is operable to cause the movement of the set of pedals 12 parallel to the axis Y between:
The set of pedals 12 is adjacent to the door sill 23 when it is in the third position.
The set of pedals 12 is in a central position between the door sills 23, 24 when it is in the fourth position.
The operation of the motor vehicle 1 is described starting from a condition in which the passenger compartment 3 is in the ‘two-seater’ configuration.
The operation of the motor vehicle 1 is also described starting from a condition in which the lever 65 is in the locking position.
In this ‘two-seater’ configuration, the location 25 defines the first seat for the driver and the second seat for a passenger arranged side-by-side parallel to the axis Y.
More precisely, the first seat is beside the door sill 23, and the second seat is beside the door sill 24 parallel to the axis Y.
As shown in
In addition, the first seat faces the steering mechanism 11 and the set of pedals 12 along the axis X to allow the driver to operate the steering mechanism 11 and the set of pedals 12 and thus control the forward trajectory and the speed of the motor vehicle 1.
If it is desired to reconfigure the motor vehicle 1 so as to arrange the passenger compartment 3 into the ‘single-seater’ configuration, it is sufficient to operate the electric motor 55 in a first direction via a dedicated control and under certain operating conditions of the motor vehicle 1.
The operation of the electric motor 55 in the first direction causes the output shafts 70, 71 and the respective flexible shafts 80, 81 to rotate in the same first direction around the axis I.
These rotations of the flexible shafts 80, 81 cause, through the respective connection elements 90, the translation of the slides 76, 77 along the respective axes J and, therefore, of the steering mechanism 11 in the first direction along the axis Y in relation to the body 2.
More specifically, the rotations of the flexible shafts 80, 81 around the axis I result in the rotation of the respective gear wheels 92 around the axis I, and the translation of the respective racks 94 and slides 76, 77 parallel to the respective axes J.
Since the transmission of motion between the gear wheels 92 and the respective racks 94 is irreversible, the slides 76, 77 remain in the desired position in the event of a stop or failure of the electric motor 55.
As a result, the steering mechanism 11 reaches the second position shown in
More precisely, the steering mechanism 11 is in a central position between the door sills 23, 24 when it is in the second position.
The system for moving the steering mechanism 11 is operated to cause the movement of the set of pedals 12 parallel to the axis Y until it reaches the fourth position.
The set of pedals 12 is in a central position between the door sills 23, 24 and faces the third position defined by the location 25 when it is in the fourth position.
The location 25 is reconfigured so as to only define the third seat for the driver, which is not necessary for the understanding of the present invention.
The single third seat is arranged in a central position between the door sills 23, 24 and faces the steering mechanism 11 and the set of pedals 12.
At this point, the passenger compartment 3 has taken on the ‘single-seater’ configuration.
The passenger compartment 3 is repositioned from the ‘single-seater’ configuration to the ‘two-seater’ configuration by simply operating the electric motor 55 in a second direction opposite the first direction, so as to return the steering mechanism 11 to the first position.
Subsequently or simultaneously, the set of pedals 12 is arranged into the third position and the location 25 is reconfigured to define the first seat for the driver and the second seat.
Both when the passenger compartment 3 is in the ‘two-seater’ configuration and when the passenger compartment 3 is in the ‘single-seater’ configuration, the position of the steering wheel 62 in relation to the body 2 along the axis H and the value of the angle α can be adjusted simply by moving the lever 65 into the unlocking position and moving the steering shaft 61 and steering wheel 62 in relation to the support body 60 and then arranging the lever 65 into the locking position once the above adjustment is complete.
The advantages enabled by the present invention will be apparent from an examination thereof.
In greater detail, the steering mechanism 11 can be moved along the axis Y between the first and the second position, so that the passenger compartment 3 can be moved between the ‘two-seater’ configuration and the ‘single-seater’ configuration.
In fact, the steering wheel 62 in the first position of the steering mechanism 11 faces, along the axis X, the first seat for the driver defined by the location 25 adjacent to the door sill 23.
Similarly, the steering wheel 62 in the second position of the steering mechanism 11 faces, along the axis X, the single third seat for the driver defined by the location 25 in a central position between the door sills 23, 24 along the axis Y.
The electric motor 55 and the transmission assembly 56 formed by the flexible shafts 80, 81 and the respective connection elements 90 ensure a fast and precise movement of the steering mechanism 11 between the above-mentioned first and second positions.
The connection elements 90 irreversibly transmit the motion from the electric motor 55 to the respective slides 76, 77 due to the presence of the coupling between respective gear wheels 92 and the corresponding racks 94.
This ensures that the slides 76, 77 remain in the desired position in the event of a stop or failure of the electric motor 55.
The fact that the slides 76, 77 are fixed to the support body 60 of the steering mechanism 12 allows the position of the steering wheel 62 along the axis H and the angle α to be adjusted by simply operating the lever 65 both when the motor vehicle 1 is in the ‘single-seater’ configuration and when the motor vehicle 1 is in the ‘two-seater’ configuration.
Lastly, it is clear that modifications and variations may be made to the motor vehicle 1 and the reconfiguration method according to the present invention, without however departing from the scope of protection defined by the claims.
In particular, in the ‘two-seater’ configuration, the first seat could be positioned facing the door sill 24 and the second seat could be positioned facing the door sill 24, thus achieving a right-hand driving mode of the motor vehicle 1.
