Description

Title of the invention: Vehicle steering wheel comprising mechanisms and a control actuator. Technical field of the invention

[0001] The present invention relates generally to a vehicle steering wheel with several mechanisms, such as articulation mechanisms to allow movement of all or part of the rim relative to the hub. Prior art

[0002] It is known in the prior art of vehicle steering wheels to provide articulation mechanisms to allow movement of all or part of the rim relative to the hub. It can also be advantageous to provide an actuator to control the movement of the moving part, and it is also possible to provide for locking the moving part in a particular position. Consequently, the number of actuators required to control all these functions can be significant, which increases complexity, cost, and size. Regarding size, the available space in a steering wheel is limited, and this can even lead to a limitation on the number of actuators and therefore on the automated functions offered to the user. Description of the invention

[0003] One object of the present invention is to address the disadvantages of the prior art mentioned above and in particular, first of all, to offer a vehicle steering wheel with mechanisms, for example articulation mechanisms to allow movement of all or part of the rim relative to the hub, and an actuator to automate functions such as locking - unlocking and / or movement of the moving part, while limiting the complexity, and / or the cost and / or the increase in size.

[0004] To this end, a first aspect of the invention relates to a vehicle steering wheel comprising: - a basic structure comprising a hub arranged to connect to a vehicle steering device, - a mobile structure, comprising at least a rim portion and articulated relative to the base structure to be mobile between a first position, for example a driving position, and a second position, for example a retracted position, - a first mechanism and a second mechanism, each arranged between the basic structure and the moving structure, - an actuator arranged to generate a drive movement for the first mechanism and the second mechanism, - a transmission device arranged to transmit at least part of the drive motion to the first mechanism and the second mechanism, characterized in that the transmission device comprises at least one cable arranged to transmit at least part of the drive motion of the actuator to at least one of the first or second mechanism.

[0005] A cable according to the above embodiment makes it possible to distribute the drive motion from a single actuator to one of the first and / or second mechanisms. Costs are limited, such a cable has a small footprint, can be shaped to bypass steering wheel components that form obstacles, and provides the possibility of having only one actuator controlling two separate mechanisms located far apart.

[0006] According to one embodiment, the cable can be arranged between the first mechanism and the second mechanism. In other words, the cable runs from the first mechanism to the second mechanism.

[0007] According to one embodiment: -1'actuator can be coupled to the first mechanism, - the second mechanism may include a locking unit arranged to reversibly lock the moving structure in the first position on the base structure, - one end of the cable can be connected to the first mechanism or actuator, - A second end of the cable can be connected to the locking unit of the second mechanism. According to this implementation, the cable is connected to the locking unit of the second mechanism from the first mechanism. Preferably, the cable is connected only to the locking unit of the second mechanism from the first mechanism, so as to control only the locking unit of the second mechanism.

[0008] According to one embodiment, the first mechanism may include a conversion device, for example a cam device and / or a desynchronizing mechanism, arranged to transform: - a first part of the drive movement in a locking-unlocking motion and, - a second part of the drive movement is dedicated to the displacement of the moving structure. In other words, starting from the first position in the locked state, the first part of the drive movement is dedicated to unlocking the moving structure, and then the second part of the drive movement is dedicated to move the mobile structure to bring it into the second position. Starting from the second (unlocked) position, the actuator delivering the drive movement in the opposite direction will generate the second part of the drive movement to move the mobile structure from the second position to the first position, and will then generate the first part of the drive movement to lock the mobile structure onto the base structure.

[0009] According to one embodiment, only the first mechanism may include a conversion device, for example a cam device and / or a desynchronizing mechanism, arranged to transform: - a first part of the drive movement in a locking-unlocking motion and, - a second part of the drive movement into a displacement movement of the mobile structure.

[0010] According to one embodiment, the second mechanism may be free of a conversion device, for example a cam device and / or a desynchronizing mechanism, or a drive device, arranged to transform the second part of the drive movement into a displacement movement of the moving structure. Consequently, the second mechanism has only a locking-unlocking function of the moving structure on the base structure, and no drive / displacement function to move the moving structure between the first and second positions.

[0011] According to one embodiment, the first mechanism may comprise: - a locking unit arranged to reversibly lock the mobile structure in the first position on the base structure, - a drive unit arranged between the actuator and the moving structure to drive the moving structure when the moving structure is unlocked from the base structure. In other words, the steering wheel includes two locking units (one on the side of the first mechanism and one on the side of the second mechanism), but only one drive unit (on the side of the first mechanism).

[0012] According to one embodiment: - during the first part of the drive movement, the cam device of the first mechanism can be arranged to engage the actuator with the locking unit of the first mechanism and disengage the actuator from the drive unit of the first mechanism, - during the second part of the drive movement, the cam device of the first mechanism can be arranged to engage the actuator with the drive unit of the first mechanism.

[0013] According to one embodiment, the cam device may include: - an input moving part attached to the actuator, comprising either an index or an opening, - a mobile output unit integral with the mobile structure, including the other part of the index or opening, The index can be positioned within the opening with sufficient play to allow movement during the initial phase of the drive movement without engaging the input and output components. Conversely, the index can be positioned to engage the opening fully, allowing the input and output components to engage during the second phase of the drive movement. This play in the index within the opening enables the locking unit and then the drive unit of the first mechanism to engage sequentially. Consequently, both functions (locking / unlocking and movement) are performed sequentially.

[0014] According to one embodiment, the vehicle steering wheel may include a stroke multiplier device arranged between the actuator and one of the first or second mechanisms connected to the actuator by at least one cable. Such a multiplier device ensures that the locking / unlocking function is completed at the second mechanism before the first mechanism. Advantageously, this stroke multiplier device can be provided between the first and second mechanisms when the cable itself is arranged between the first and second mechanisms. This is particularly useful if the first mechanism performs both the locking / unlocking and steering functions, to ensure that the steering function is not implemented before the second mechanism is unlocked.

[0015] According to one embodiment, the stroke multiplier device can be arranged to generate a locking-unlocking stroke on the side of the second mechanism greater than a locking-unlocking stroke on the side of the first mechanism.

[0016] According to one embodiment, the stroke multiplier device may include: - a first rotary input mobile on the side of the first mechanism defining a first anchoring radius of the cable on the first rotary input mobile, - a second rotating input mobile on the side of the second mechanism defining a second anchoring radius for the cable on the second rotating input mobile, in which the first anchor radius can be greater than the second anchor radius.

[0017] According to one embodiment, the vehicle steering wheel may include a sheath, preferably fixed relative to the basic structure, and receiving said at least one cable.

[0018] According to one embodiment, the actuator, the first mechanism, the cable and the The second mechanism can be connected in series to each other.

[0019] According to one embodiment, the second mechanism can be connected to the actuator via the cable in parallel with the first mechanism.

[0020] According to one embodiment, the cable, in particular an output end of the cable, can control (output) a sliding element.

[0021] According to one embodiment, the cable, in particular an output end of the cable, can control (at output) a rotating element, preferably in the same direction of rotation as a direction of rotation of an input control rotating element of the cable.

[0022] According to one embodiment, the cable may have a round or flat cross-section and may preferably be composed of several strands, for example more than 5 strands, typically 7 strands. The use of multi-strand cable makes it possible to reduce the bending radii and thus integrate more easily into the steering wheel environment.

[0023] According to one embodiment, the actuator can be an electric motor or an electric geared motor.

[0024] According to one embodiment, the vehicle steering wheel may include a single actuator to control the first mechanism and the second mechanism.

[0025] According to one embodiment, the first mechanism and the second mechanism can each be arranged on either side of the hub.

[0026] According to one embodiment, the first mechanism and the second mechanism can each include a linkage unit, such as a pivot linkage defining an axis of rotation of the mobile structure relative to the base structure.

[0027] According to one embodiment, the moving structure may include the entire rim and at least a part of the spoke connecting the rim to the hub.

[0028] According to one embodiment, the basic structure may include a rim part and the moving structure may include another rim part. Description of the figures

[0029] Other features and advantages of the present invention will become more apparent upon reading the following detailed description of two embodiments of the invention given by way of non-limiting examples and illustrated by the accompanying drawings, in which:

[0030] [Fig. 1] represents a front view of a vehicle steering wheel according to a first embodiment comprising a hub with a plate, a rim, spokes connecting the rim to the hub;

[0035] [Fig.6] represents a detail of the vehicle steering wheel of [Fig.5];

[0036] [Fig.7] represents another detail of the vehicle steering wheel of [Fig.5]. Detailed description of implementation method(s)

[0037] Figure 1 represents a vehicle steering wheel comprising: - a hub 11 with a plate 12 forming a basic structure 10, - a rim 21 with spokes 22 forming a movable structure 20, - a first mechanism 30 and a second mechanism 40 arranged between the base structure 10 and the mobile structure 20. It can be noted that the plate 12 is optional and / or could have any other geometric shapes.

[0038] The mobile structure 20 can be moved relative to the base structure 10. In the present example, the first mechanism 30 and the second mechanism 40 each include a pivot joint, so that the entire rim 21 can pivot relative to the base structure 10. However, other types of joints can be provided, such as slides or combined movements of rotations and / or translations.

[0039] In the present example, the first mechanism 30 and the second mechanism 40 are fixed on the plate 12 which is integral with the hub 11, and each includes a central shaft (respectively 23 and 24) integral with the moving structure and mounted in pivot connection on each mechanism via a hub.

[0040] The first mechanism 30 and the second mechanism 40 each also comprise two flanges 31, 32 and 41, 42 respectively, which sandwich the main moving parts of each mechanism. It should be noted that the first mechanism 30 and the second mechanism 40 are each arranged on either side of the hub 11, which provides good guidance of the moving structure, with good resistance to deformation, and with short overhang distances.

[0041] As shown in [Fig. 2], the vehicle's steering wheel includes a motor 50 forming an actuator that generates a drive motion distributed to the first mechanism 30 and the second mechanism 40 by a drive device. An electric motor and / or a geared motor may be provided.

[0042] Generally speaking, as shown in Figures 2 to 4, in the present example, the drive device comprises: - an input pinion 53, which is engaged with the first mechanism 30, and - a cable 51, housed in a sheath 52, which runs from the first mechanism 30 to drive the second mechanism 40. The cable 51 could just as easily run from the input pinion 53, or even motor 50. The cable can be a multi-strand wire rope, with one or more strands. It can be overmolded with a low-friction material (PTFE) to limit sliding forces within the sheath 52. The sheath 52 can be flexible or rigid.

[0043] However, it can be noted that a single motor 50 is sufficient to drive the first mechanism 30 and the second mechanism 40, thanks to the cable which is generally arranged between the motor 50 and at least one of the mechanisms 30 or 40. It can also be noted that the sheath 52 follows a convoluted path to follow the components of the flywheel while minimizing the overall size. Thus, the cable drive system makes it possible to limit the required space with a single motor 50 and a cable 51-sheath 52 assembly that runs as close as possible to the hub 11 and the plate 12.

[0044] In detail, the mobile structure 10 is mobile between a first position (as in [Fig.1], a driving position in which a user can grasp the rim 11 to drive the vehicle), and a second position (not shown, for example retracted or so-called console), to place a computer on the rim 11, or to free up space in case of stopping the vehicle or autonomous driving.

[0045] To this end, the movable structure 10 is intended to be blocked or locked in the first position to ensure safe operation. For this purpose, a locking unit is provided in the first mechanism 30 and the second mechanism 40.

[0046] With regard to the movement of the mobile structure 20, only the first mechanism 30 is arranged to transform the drive movement of the motor 50 into a movement of the mobile structure 20.

[0047] In summary, it is planned to lock the mobile structure 20 onto the base structure 10 on both sides of the hub 11 with the first mechanism 30 and the second mechanism 40, while the movement of the mobile structure 20 is controlled only from the side of the first mechanism 30. This provides safety during driving (the rim 21 is doubly locked onto the hub 11), and economy of means (only the first mechanism 30 needs to be able to move the mobile structure 20).

[0048] In particular, the first mechanism 30, as shown in Figures 3 and 4, comprises: - a drive pinion 35 coupled in direct contact with the input pinion 53 - an index 38 mounted on one of the lateral faces of the drive pinion 35, - a first movable plate 37 comprising an opening in which the index 38 is arranged with an angular clearance al ([Fig.4]), and mounted freely in rotation with the drive pinion 35 (the first movable plate 37 can pivot relative to the drive pinion 35), - the central shaft 23 already mentioned above and fixed in rotation with the first movable plate 37, - a first rocker 34, pivotally mounted on the flanges 31, 32 (visible only [Fig.2]), and constantly pushed towards the drive pinion 35 by an elastic tab 341 in contact with the flanges 31, 32, - a first locking pin 33 mounted on the first rocker 34 - a return spring 39 engaged between the central shaft 23 and the control pinion 53.

[0049] As can be seen [Fig. 3], the drive pinion 53 is partially toothed, and a cam track 36 is arranged around the periphery of the drive pinion 53, opposite the rocker arm 34, to actuate it as will be explained below. Furthermore, the drive pinion 53 includes a housing that receives a first end 511 of the cable 51.

[0050] As regards the second mechanism 40, the latter is simpler because it comprises, as shown in Figures 2 and 4: - a 45-unit control unit, - a second movable plate 47 free to rotate relative to the control movable part 45, - a second rocker 44, pivotally mounted on the flanges 41, 42 (visible only [Fig.2]), and constantly pushed towards the control mechanism by an elastic tab 441 engaged with the flanges 41, 42, - a second locking pin 43 mounted on the second rocker arm 34 - the central shaft 24, - a return spring 49 engaged between the central shaft 24 and the control moving part 45.

[0051] The control wheel 45 includes a housing for receiving the second end 512 of the cable 51, and a cam track 46 arranged peripherally opposite the second rocker arm 44. As can be seen [Fig. 3], the cable 51 mounting ensures that the control pinion 35 drives the control wheel 45 in the same direction of rotation. The spring 49 ensures that the second end 512 of the cable 51, which in this example is fitted with a ball bearing, is always in contact with the housing of the control wheel 45. This ensures backlash-free operation and allows for compensation of manufacturing tolerances, particularly in length, of the cable 51.

[0052] As shown in [Fig. 3], the first end 511 of the cable 51 is located at a first anchor radius RI of the axis of rotation of the drive pinion 35, and as shown in [Fig. 4], the second end 512 of the cable 51 is located at a second anchor radius R2 of the axis of rotation of the drive wheel 45. The second anchor radius R2 is smaller than the first anchor radius RI, which provides a stroke-multiplying device that allows the angular stroke of the drive wheel 45 to be multiplied relative to the drive pinion 35, as This will be explained below. Naturally, the cam track 46 is adjusted accordingly for this travel multiplier. Thus, when the steering wheel is equipped with a travel multiplier device, the cam tracks 36 and 46 are different.

[0053] According to this first embodiment, the flywheel actuator, i.e. the motor 50, generates a drive movement sequentially: - to control the locking mechanism, - move the mobile structure. For this purpose, a conversion device with a cam device and a desynchronization device is provided.

[0054] In detail, starting from the driving position in which the mobile structure 20 is locked onto the base structure 10 via the first locking pin 33 and the second locking pin 43: - the motor 50 drives the input pinion 53 in rotation, which in turn drives the control pinion 35 in rotation, - as a result, the control pinion 35 causes, on the one hand, the tilting of the first rocker arm 34 via the cam track 36, and on the other hand, the rotation of the control moving part 45 via the cable 51, - the rotation of the control mechanism 45 simultaneously causes the second rocker arm 44 to tilt via the cam track 46, - thus, the first locking pin 33 and the second locking pin 43 move and unlock the moving structure 20 from the base structure 10. The cam device therefore transforms the first part of the drive movement into the unlocking movement.

[0055] However, at this stage, due to the angular play a1 between the opening of the first moving plate 37 and the index 38, no movement is transmitted to the first moving plate 37. Moreover, thanks to the stroke multiplication device provided by the difference in the anchoring radii RI and R2, the unlocking is faster on the side of the second mechanism 40 and therefore is certainly completed before the drive of the first moving plate 37. Thus, a first part of the drive movement of the motor 50 allows the moving structure 20 to be unlocked.

[0056] Once the first rocker arm 34 is fully pivoted to completely unlock the moving structure 20 from the base structure 10, the index 38, having traveled the entire path of the angular play a1, can reach the stop on the first moving plate 37 and cause it to rotate, which causes the central shaft 23, and therefore the moving structure 20, to move to its second position. The moving structure is thus retracted or in a console position (the rim can be horizontal to place, for example, a laptop computer). A second part of the drive movement of the motor 50 then moves the moving structure 20. In other words, the desynchronizing device (the index 38 in the opening of the first plate) mobile 37) allows not to transform the first part of the drive movement into a displacement movement: the desynchronization device only transforms the second part of the drive movement into a displacement movement of the mobile structure 20.

[0057] To return to the first position, the motor 50 is driven in the opposite direction of rotation to rotate the input pinion 53 and the drive pinion 35. Due to the springs 39 and 49, the movable structure 20 is automatically returned to the first position; that is, on the side of the first mechanism 30, the first movable plate 37 follows the index 38 during the angular stroke corresponding to the second part of the drive movement. On the side of the second mechanism 40, the drive pinion 45 is also returned to rotation by the spring 49 (tensioned by the movable structure which includes the central shaft 24).

[0058] Once this part of the stroke is completed, the moving structure 20 returns to its initial position, and locking can be achieved. The motor 50 continues to rotate the drive pinion 35, causing the cam track 36 to release the first rocker arm 34, which is constantly pushed against the drive pinion 35 by the elastic tab 341. Thus, the first locking pin 33 returns to the position that locks the moving structure 20. On the side of the second mechanism 40, the drive pin 45 also rotates, which likewise releases the second rocker arm 44, which is constantly pushed against the drive pin 45 by the elastic tab 441. Thus, the second locking pin 43 also returns to the position that locks the moving structure 20.

[0059] In this embodiment, the same actuator is therefore used to control both the locking and the movement of the moving structure. This function is achieved here by locking and drive units based on cam mechanisms with angular clearances, but clutch mechanisms, ratchet mechanisms, etc., could also be used.

[0060] Figure 5 shows a second embodiment, in which only a portion of the rim is movable, and where the locking is performed by a dedicated actuator. As Figure 5 shows, the vehicle's steering wheel comprises: - a basic structure 110 with a hub 111, a plate 112, spokes 113, a rim section 114, - a movable structure 120 with another rim part 121, and spoke parts 122, - a locking actuator (a first motor 150), - a drive device with two cables 151 (visible in figures 6 and 7) and two sheaths 152, and a drive return device 153, - two mechanisms 131 (only one visible [Fig.6]), - a displacement actuator (a second motor 160), - a displacement return device 161.

[0061] In this embodiment, the base structure 110 includes a rim part 114, and the movable structure 120 includes another rim part 121, connected to the base structure 110 by pivot links (the spoke parts 122 are mounted in bearings of the base structure 110).

[0062] The mobile structure 120 is therefore mobile between: - a first position ([Fig.5]) in which it is locked onto the basic structure 110 and - a second position (not shown) in which the other rim part 121 is inclined relative to the rim part 114 of the base structure 110.

[0063] Two mechanisms 131 ([Fig.6]) are provided on either side of the plate 112, between the base structure 110 and the mobile structure 120, to lock it in the first position on the base structure 110. These two mechanisms 131 include a sliding lock (mobile in translation relative to the base structure 110) which can enter an opening in the mobile structure 120 in order to prevent any rotational movement of the mobile structure 120.

[0064] The first motor 150 is connected to each of the mechanisms 131 by cables 151 mounted in sheaths 152 which run along the plate 112 between the first motor 150 and each of the mechanisms 131.

[0065] As shown in [Fig.7], a drive return device 153 is coupled to the first motor 150 to drive, via a bevel gear, two pulleys each connected to one of the cables 151. Thus, the rotation of the first motor 150 causes the two cables 151 to slide in the sheaths 152, which causes the lock of each mechanism 131 to slide.

[0066] Furthermore, still [Fig.7], it can be noted that the second motor 160, attached to the base structure 110, is coupled to a displacement transfer mechanism 161 (another conical couple) in order to be able to move the mobile structure 120.

[0067] To move the mobile structure from the first position of [Fig.5] or 7 to the second position, it is therefore necessary first to activate the first motor 150 to move the locks of the mechanisms 131 and unlock the mobile structure 120 from the base structure 110.

[0068] Once the unlocking has been carried out, the second motor 160 can be activated to rotate the mobile structure 120 and thus tilt the other rim part 121 relative to the rim part 114 of the base structure 110.

[0069] Conversely, to move the mobile structure from the second position to the first position of [Fig. 5] or 7, the second motor 160 must be actuated to rotate the mobile structure 120. Once the mobile structure 120 is in the first position (the other part of rim 121 aligned with respect to the part of rim 114 of the base structure 110), we can actuate the first motor 150 to move the locks of the mechanisms 131 and (re)lock the mobile structure 120 on the base structure 110.

[0070] Thus, according to this implementation, a single actuator can control two locking mechanisms, which limits the size of this locking function.

[0071] It can be noted that the first motor 150 could be directly connected to one of the locks so as to require only one cable 151. However, the use of two cables 151 allows the first motor 150 to be placed anywhere on the flywheel. Industrial application

[0072] A vehicle steering wheel according to the present invention, and its manufacture, are capable of industrial application.

[0073] It will be understood that various modifications and / or improvements obvious to a person skilled in the art can be made to the different embodiments of the invention described in this description without departing from the scope of the invention.

[0074] In particular, it can be noted that the actuators can be fixed to the moving structure. Motors with racks, return levers, ratchets, and clutches can also be provided to separate the locking / unlocking function from the movement function.

[0075] The structure of the steering wheel can be different with a hub without a plate, or a non-circular rim, for example oval or even open in a U shape. Other relative movements between the moving structure and the base structure can be provided (translations, sliding pivots, combined rotations...).

[0076] With regard to the elastic legs of the rocker arms, it is possible to provide for them to be put under variable tension during the drive movement, for example with a cam track on the control pinion or on the control moving part which increases the tension only during the part of the stroke where the locking must be carried out.

[0077] The steering wheel is shown here without a cover, but the frame shown can of course be overmolded with a cover.
