[0025] With reference to the second aspect, in some implementations of the second aspect, when the steering wheel is in the third mode, the third arc-shaped hub portion and the fourth arc-shaped hub portion are in the fourth plane; when the steering wheel is in the fourth mode, the fourth connecting portion is configured to drive the fourth arc-shaped hub portion to rotate to a fifth plane in a first direction, and the third connecting portion is configured to drive the third arc-shaped hub portion to rotate to the fifth plane in the first direction, and the fifth plane and the first plane form a third preset angle.

[0026] The third mode can also be referred to as a non-storage mode, and the third mode can correspond to a driving mode of the vehicle, i.e., when the vehicle starts the driving mode, the steering wheel is in the third mode.

[0027] In a possible implementation, the first direction can be a clockwise direction or a counterclockwise direction.

[0028] In a possible implementation, the steering wheel further includes an electric driving assembly configured to drive the third arc-shaped hub portion and the fourth arc-shaped hub portion to move into the vehicle body.

[0029] In the embodiments of the present application, the fourth arc-shaped hub portion and the third arc-shaped hub portion can rotate to the fifth plane in the same direction during the storage of the steering wheel, which can facilitate the storage of the steering wheel and further improve the comfort of the driver when the steering wheel is in the storage state.

[0030] With reference to the second aspect, in some implementations of the second aspect, when the stowable steering wheel is in the third mode, the third arc-shaped hub portion and the fourth arc-shaped hub portion are in a fourth plane; when the stowable steering wheel is in the fourth mode, the fourth connecting portion is configured to rotate the fourth arc-shaped hub portion to a sixth plane in a first direction, and the third connecting portion is configured to rotate the third arc-shaped hub portion to a seventh plane in the first direction, an angle between the sixth plane and the fourth plane is a fourth preset value, an angle between the seventh plane and the fourth plane is a fifth preset value, and the fourth preset value and the fifth preset value are different.

[0031] With reference to the second aspect, in some implementations of the second aspect, the third connecting portion includes a fourth connecting shaft and a fifth connecting shaft, the fourth connecting shaft and the fifth connecting shaft are in a same line, and the fourth connecting shaft and the fifth connecting shaft are configured to realize the third rotating shaft.

[0032] With reference to the second aspect, in some implementations of the second aspect, the fourth connecting portion includes a sixth connecting shaft, a fifth connecting rod, a sixth connecting rod, a seventh connecting rod, and an eighth connecting rod, the sixth connecting shaft is configured to realize the fourth rotating shaft, a first end of the sixth connecting shaft is connected to a first end of the sixth connecting rod through the fifth connecting rod, a second end of the sixth connecting shaft is connected to a first end of the eighth connecting rod through the seventh connecting rod, the sixth connecting rod and the eighth connecting rod are in a same line and are parallel to the sixth connecting shaft, and second ends of the sixth connecting rod and the eighth connecting rod are connected to two ends of the fourth arc-shaped hub portion respectively.

[0033] In the embodiments of the present application, the first rotating shaft can be realized by the fourth connecting shaft and the fifth connecting shaft, the second rotating shaft can be realized by the sixth connecting shaft, and the diameters of the third arc-shaped hub portion and the fourth arc-shaped hub portion are different when the stowable steering wheel is in the fourth mode. Such a configuration can ensure that the third arc-shaped hub portion and the fourth arc-shaped hub portion do not interfere with each other during stowage, and the structure of the lower rim can be strengthened by the fifth connecting rod to the eighth connecting rod, which is conducive to better stowage of the fourth arc-shaped hub portion.

[0034] With reference to the second aspect, in some implementations of the second aspect, the sixth connecting shaft comprises: a first connecting segment and a second connecting segment; when the stowable steering wheel is in the third mode, the first connecting segment and the second connecting segment are separated, so that the length of the fourth connecting portion parallel to the direction of the sixth connecting shaft is a first length; when the stowable steering wheel is in the fourth mode, the first connecting segment and the second connecting segment are connected, so that the length of the fourth connecting portion parallel to the direction of the sixth connecting shaft is a second length, and the second length is less than the first length.

[0035] In the embodiments of the present application, when the stowable steering wheel is in the fourth mode, the first connecting segment and the second connecting segment can be connected, so as to reduce the length of the fourth connecting portion parallel to the direction of the sixth connecting shaft, thereby reducing the lower rim. In this way, it can be ensured that the third arc-shaped hub portion and the fourth arc-shaped hub portion are in the same plane in the stowed state of the stowable steering wheel, thereby effectively saving the space in the vehicle.

[0036] With reference to the second aspect, in some implementations of the second aspect, the fourth arc-shaped hub portion is provided with a first telescopic portion; when the stowable steering wheel is in the third mode, the first telescopic portion is in an extended state, so that the diameter of the fourth arc-shaped hub portion is a third length; when the stowable steering wheel is in the fourth mode, the first telescopic portion is in a compressed state, so that the diameter of the fourth arc-shaped hub portion is a fourth length, and the fourth length is less than the third length.

[0037] In the embodiments of the present application, when the stowable steering wheel is in the fourth mode, the first telescopic portion can be in a compressed state, so as to reduce the diameter of the fourth arc-shaped hub portion, thereby reducing the lower rim. In this way, it can be ensured that the third arc-shaped hub portion and the fourth arc-shaped hub portion are in the same plane in the stowed state of the stowable steering wheel, thereby effectively saving the space in the vehicle.

[0038] With reference to the second aspect, in some implementations of the second aspect, the difference between the first length and the second length is equal to the difference between the third length and the fourth length.

[0039] With reference to the second aspect, in some implementations of the second aspect, the third arc-shaped hub portion is provided with a second telescopic portion; when the stowable steering wheel is in the third mode, the second telescopic portion is in a compressed state, and the diameter of the third arc-shaped hub portion is a fifth length; when the stowable steering wheel is in the fourth mode, the second telescopic portion is in an extended state, and the diameter of the third arc-shaped hub portion is a sixth length, and the sixth length is greater than the fifth length.

[0040] In the embodiments of the present application, when the stowable steering wheel is in the fourth mode, the second telescopic part is in the extended state, thereby increasing the diameter of the third arc-shaped hub part to expand the upper rim. In this way, the third arc-shaped hub part and the fourth arc-shaped hub part are in the same plane in the stowed state of the stowable steering wheel, thereby effectively saving the space in the vehicle.

[0041] With reference to the second aspect, in some implementations of the second aspect, the diameter of the third arc-shaped hub part is a seventh length, and the diameter of the fourth arc-shaped hub part is an eighth length, the eighth length being less than the seventh length.

[0042] In the embodiments of the present application, when the stowable steering wheel is in the third mode or the fourth mode, the diameter of the fourth arc-shaped hub part is always less than the diameter of the third arc-shaped hub part. In this way, the third arc-shaped hub part and the fourth arc-shaped hub part are in the same plane in the stowed state of the stowable steering wheel, thereby effectively saving the space in the vehicle.

[0043] With reference to the second aspect, in some implementations of the second aspect, the first connecting part is a third gear for implementing the third rotating shaft, and the second connecting part is a fourth gear for implementing the fourth rotating shaft.

[0044] In the embodiments of the present application, the third connecting part is a third gear, and the fourth connecting part is a fourth gear. Such a processing manner can simplify the structure of the third connecting part and the fourth connecting part, and is conducive to ensuring that the third arc-shaped hub part and the fourth arc-shaped hub part rotate in the same direction.

[0045] In a third aspect, a vehicle is provided, which includes the stowable steering wheel in any one of the implementations of the first aspect or the second aspect.

[0046] In a fourth aspect, a steering wheel is provided. The steering wheel (10) includes an upper hub part (100), a lower hub part (200), and a central part (300). The steering wheel (10) has a driving mode and a stowed mode. When the steering wheel (10) is in the driving mode, the upper hub part (100) and the lower hub part (200) jointly enclose a ring-shaped structure around the central part (300) for a user to hold, and the upper hub part (100) and the lower hub part (200) are respectively located on the upper side and the lower side of the ring-shaped structure. When the steering wheel (10) is in the stowed mode, the upper hub part (100) and the lower hub part (200) are both stowed below and behind the central part (300).

[0047] In actual scenarios, the steering column is usually arranged obliquely, and the instrument panel of the vehicle is usually arranged above the steering column in the height direction of the vehicle, and sufficient leg space can be provided for the user below the instrument panel. If the steering wheel is stored in other ways, such as being stored in the instrument panel, not only does the steering column need to be arranged in the instrument panel (for example, the steering column can need to be extended horizontally from the instrument panel), but also a storage space for the steering wheel needs to be reserved in the instrument panel; because the instrument screen, air outlet and the like usually occupy a large space of the instrument panel, it is often difficult to successfully arrange the storage space for the steering wheel in the instrument panel. Even if the size of the steering wheel is reduced to successfully arrange the storage space, on the one hand, the steering experience of the user will be poor due to the too small size of the steering wheel, and on the other hand, the design and structure of the related components such as the steering column in the steering system need to be adjusted on a large scale, which makes it difficult for this way to have good universality for different vehicle models, thereby resulting in high costs.

[0048] In the present application, in the storage mode, the upper hub part and the lower hub part can be stored below the rear of the central part, and the steering wheel can be fully stored by using the existing leg space in the vehicle. Especially in the case where the steering column has a telescopic function, after the steering column is shortened, the stored steering wheel can also effectively avoid interference with the instrument panel. Compared with the scheme of storing the steering wheel in the instrument panel, the related components such as the steering column in the steering system do not need to be adjusted on a large scale, have high universality for different vehicle models, and thus the storage of the steering wheel can be realized at low cost and system complexity. Moreover, since the upper hub part and the lower hub part are independent components, when the annular structure has a large radial dimension, the storage mode can also guarantee good storage effect.

[0049] In some possible implementation manners, the steering wheel (10) can further include a fifth connecting part (400) and a sixth connecting part (500). The upper hub part (100) can be connected with the central part (300) through the fifth connecting part (400), and the fifth connecting part (400) can include a rotating shaft arranged along a first axis (401), and the upper hub part (100) can rotate along the first axis (401); the lower hub part (200) can be connected with the central part (300) through the sixth connecting part (500), and the sixth connecting part (500) can include a rotating shaft arranged along a second axis (501), and the lower hub part (200) can rotate along the second axis (501).

[0050] In some possible implementation manners, the upper hub portion (100) and the lower hub portion (200) can be in the eighth plane when the steering wheel (10) is in the driving mode. The fifth connecting portion (400) can be used to drive the upper hub portion (100) to rotate in the first direction to the ninth plane, and the sixth connecting portion (500) can be used to drive the lower hub portion (200) to rotate in the first direction to the tenth plane when the steering wheel (10) is in the storage mode.

[0051] In some possible implementation manners, the second axis (501) is parallel to the first axis (401), and the second axis (501) is located above the first axis (401).

[0052] In some possible implementation manners, an included angle between the ninth plane and the eighth plane can be a first preset value, and an included angle between the tenth plane and the eighth plane can be a second preset value.

[0053] In some possible implementation manners, diameters of the upper hub portion (100) and the lower hub portion (200) can be different when the steering wheel (10) is in the storage mode.

[0054] In some possible implementation manners, the first axis (401) and the second axis (501) can be the same axis; and / or, the ninth plane and the tenth plane are the same plane, and an included angle between the ninth plane and the eighth plane is a third preset value.

[0055] In some possible implementation manners, the fifth connecting portion (400) includes a rotating shaft arranged along the first axis (401), including the seventh connecting shaft (410) and the eighth connecting shaft (420), and the seventh connecting shaft (410) and the eighth connecting shaft (420) are arranged on opposite sides of the central portion (300); and / or, the sixth connecting portion (500) includes a rotating shaft arranged along the second axis (501), including the ninth connecting shaft (510) and the tenth connecting shaft (520), and the ninth connecting shaft (510) and the tenth connecting shaft (520) are arranged on opposite sides of the central portion (300).

[0056] In the present application, the seventh connecting shaft and the eighth connecting shaft arranged along the first axis are arranged on opposite sides of the central portion, so that the two connecting shafts can be arranged in a symmetrical manner, which is beneficial to weight balancing of the left and right sides of the steering wheel, so that the steering wheel can be kept in a neutral position when it is not turned by a user, thereby avoiding unexpected turning / yawing of the vehicle. Moreover, arranging the seventh connecting shaft and the eighth connecting shaft on opposite sides of the central portion is also beneficial to reducing the occupation of the core space of the central portion by these connecting shafts, and can avoid these connecting shafts occupying the arrangement space of the airbag.

[0057] In some possible implementation manners, the steering wheel 10 can further include a first motor 330 and a first transmission assembly 340. The first transmission assembly 340 can be configured to drive connect the seventh connecting shaft 410 to the first motor 330, so that the first motor 330 drives the seventh connecting shaft 410 to rotate along the first axis 401.

[0058] In this application, by arranging the first motor and the first transmission assembly, the user can simplify the adjustment process of the posture of the steering wheel. In particular, in this way, the posture adjustment of the steering wheel can be linked with other intelligent functions of the vehicle, which can enrich the user's experience.

[0059] In some possible implementation manners, the steering wheel 10 can further include a second transmission assembly 350. The second transmission assembly 350 can be configured to drive connect the ninth connecting shaft 510 to the first motor 330, so that the first motor 330 drives the ninth connecting shaft 510 to rotate along the second axis 501.

[0060] In this application, the same motor is used to drive the seventh connecting shaft and the ninth connecting shaft to rotate through different transmission assemblies, which can save the layout space in the steering wheel and save costs. In addition, since the seventh connecting shaft is connected to the upper hub part and the ninth connecting shaft is connected to the lower hub part, when the steering wheel is switched between the driving mode and the storage mode, it is beneficial to realize the synchronous rotation of the upper hub part and the lower hub part, which is beneficial to reduce the complexity of control and shorten the time required for mode switching.

[0061] In some possible implementation manners, the speed reduction ratio of the first transmission assembly 340 can be less than the speed reduction ratio of the second transmission assembly 350.

[0062] Since the upper and lower hub parts are stored below the rear of the central part in the storage mode, the angle of rotation required by the upper hub part will be greater than the angle of rotation required by the lower hub part when the posture of the steering wheel is switched. In this application, by reasonably setting the transmission ratios of the first transmission assembly and the second transmission assembly, it is beneficial for the upper and lower hub parts to change their postures in the same time period when the mode of the steering wheel is switched, which is beneficial to save the total time required for mode switching.

[0063] In some possible implementation manners, the first motor 330 can have a self-locking function.

[0064] In this application, by using the first motor with a self-locking function, the upper and lower hub parts can be locked in the corresponding postures without the need to arrange a mechanical locking mechanism, which is beneficial to save the layout space in the steering wheel.

[0065] In some possible implementation manners, the steering wheel (10) can further include a first lock pin (363), the upper hub portion (100) can include a first lock hole (112) matched with the first lock pin (363), and the lower hub portion (200) can include a second lock hole (212) matched with the first lock pin (363).

[0066] In the present application, since the first lock hole and the second lock hole can be matched with the first lock pin, the upper hub portion and the lower hub portion can be locked at the same time through the lock pin, compared with the mode of using multiple lock pins to lock the upper hub portion and the lower hub portion respectively, the number of parts used to drive the movement of the lock pin in the steering wheel can be reduced, which is beneficial to saving the arrangement space in the steering wheel.

[0067] In some possible implementation manners, the first lock hole (112) and the second lock hole (212) can be coaxially arranged.

[0068] In the present application, the first lock hole and the second lock hole are coaxially arranged, which can further save the space occupied by the lock pin, and can also avoid the failure mode that the first lock pin can only be matched with one of the lock holes due to rotation.

[0069] In some possible implementation manners, the steering wheel (10) can further include a second motor (370) and a third transmission assembly (380). The third transmission assembly (380) can be used to transmissionally connect the first lock pin (363) to the second motor (370), so as to move the first lock pin (363) relative to the first lock hole (112) and the second lock hole (212).

[0070] In the present application, the second motor is used to drive the lock pin, which can save the manual locking and unlocking operation of the user on the upper hub portion and the lower hub portion, and is also beneficial to linkage with other actuators in the cabin, so as to provide a more rich experience for the user.

[0071] In some possible implementation manners, the third transmission assembly (380) can include a first transmission rod (381), a first lock pin seat (382) used to arrange the first lock pin (363), and a fourth transmission assembly (383). The first lock pin seat (382) can be connected with the first transmission rod (381) and can move in the locking direction of the first lock pin; and the fourth transmission assembly (383) can be used to transmissionally connect the first transmission rod (381) to the second motor (370).

[0072] In some possible implementation manners, the first transmission rod (381) and the first lock pin seat (382) can be transmissionally connected in a threaded manner.

[0073] In the present application, the first transmission rod and the first lock pin seat are transmissionally connected in a threaded manner, which can reduce the total length of the parts in the third transmission assembly that can move in the locking direction of the lock pin, and is beneficial to saving the arrangement space in the steering wheel.

[0074] In some possible implementation manners, the first locking pin (363) can be inserted into the first locking hole (112) and the second locking hole (212) when the steering wheel (10) is in the driving mode, and the first locking pin (363) can be outside the first locking hole (112) and the second locking hole (212) when the steering wheel (10) is in the storage mode.

[0075] In some possible implementation manners, the steering wheel (10) can further include a second locking pin (364) and a fifth transmission assembly (390), and the first locking pin (363) and the second locking pin (364) can be arranged on opposite sides of the steering wheel (10). The upper hub (100) can further include a third locking hole matched with the second locking pin (364), and the lower hub (200) can further include a fourth locking hole matched with the second locking pin (364); and the fifth transmission assembly (390) can be used to drive the second locking pin (364) to be connected to the second motor (370).

[0076] In the present application, by arranging the second locking pin, the upper and lower hubs can still be locked when the locking of the first locking pin fails, which can improve the redundancy of the system. In addition, the same motor is used to drive the first locking pin and the second locking pin through different transmission assemblies, which can save the layout space in the steering wheel, save costs, and also reduce the complexity of control.

[0077] In some possible implementation manners, the second motor (370) and the first motor (330) can be arranged on opposite sides of the steering wheel (10), respectively.

[0078] In the present application, the first motor and the second motor are arranged on opposite sides of the steering wheel, which is beneficial to the weight balance of the left and right sides of the steering wheel. By arranging a lighter counterweight or even without an additional counterweight, the steering wheel can be kept in a neutral position, so that the unintended turning / yawing of the vehicle can be avoided.

[0079] In a fifth aspect, a steering control system is provided. The steering control system can include a steering wheel and a steering column; and the steering wheel can be connected with the steering column. The steering wheel can be the steering wheel in the first aspect, the second aspect, or the fourth aspect, or any possible implementation manner thereof.

[0080] In some possible implementation manners, the steering column can include a multi-stage pipe column coaxially arranged along a third axis, and adjacent two stages of the multi-stage pipe column can be relatively movable along the third axis.

[0081] In a sixth aspect, a vehicle is provided. The vehicle can include the steering wheel in the first aspect, the second aspect, or the fourth aspect, or any possible implementation manner thereof, or can include the steering control system in the fifth aspect, or any possible implementation manner thereof.

[0109] Optionally, the first connecting portion and the second connecting portion can be gears, connecting shafts or the like.

[0110] Specifically, the storable steering wheel can be applied to Figure 1 the vehicle as shown.

Wherein, the first arc-shaped hub portion and the second arc-shaped hub portion can refer to the part that the driver holds with hands to rotate the steering wheel, and through the first arc-shaped hub portion and the second arc-shaped hub portion, the driver can easily control the vehicle to realize the operations such as turning, steering and adjusting the driving direction of the vehicle.

[0112] Optionally, the storable steering wheel further comprises a central portion, the central portion being installed on a steering column of the vehicle, all or part of the first connecting portion and the second connecting portion can be located in the central portion, and the first rotation shaft and the second rotation shaft can be located in the central portion; functional buttons such as sound control buttons, cruise control buttons, telephone answering buttons and the like can be arranged on the central portion. The arrangement of these functional buttons can make the driver more convenient to operate various functions on the vehicle during driving, thereby improving the convenience and comfort of driving. On the other hand, an airbag cover can be arranged on the central portion, and a safety airbag in the airbag cover can be rapidly inflated and unfolded when the vehicle collides, thereby providing protection for the driver and reducing the harm caused by the collision.

[0113] In the embodiments of the present application, since the second rotating shaft of the stowable steering wheel is located above the first rotating shaft, such arrangement can make the first arc-shaped hub portion and the second arc-shaped hub portion not interfere with each other during the stowing process, thereby providing a structural basis for the first arc-shaped hub portion and the second arc-shaped hub portion to rotate in the same direction, and such arrangement can improve the comfort of the driver in the stowed state of the stowable steering wheel and effectively save the space inside the vehicle.

[0114] In a possible implementation, when the stowable steering wheel is in the first mode, the first arc-shaped hub portion and the second arc-shaped hub portion are in the first plane; when the stowable steering wheel is in the second mode, the second connecting portion is used to drive the second arc-shaped hub portion to rotate in the first direction to the second plane, and the first connecting portion is used to drive the first arc-shaped hub portion to rotate in the first direction to the third plane, the included angle between the second plane and the first plane is a first preset value, and the included angle between the third plane and the first plane is a second preset value.

[0115] The first mode can be a non-stowed mode of the stowable steering wheel, which can correspond to a driving mode of the vehicle, i.e., the stowable steering wheel is in the first mode when the vehicle is driving or the driving mode is turned on; the second mode can be a stowed mode of the stowable steering wheel, which can correspond to a parking mode of the vehicle, i.e., the stowable steering wheel is in the second mode when the parking mode of the vehicle is turned on.

[0116] Optionally, the first direction can be a clockwise direction or a counterclockwise direction.

[0117] Optionally, the first preset value and the second preset value can be equal (for example, the first preset value is equal to the second preset value, which is equal to 60 degrees), i.e., the second plane can be parallel to the third plane.

[0118] Optionally, the stowable steering wheel further comprises an electric driving assembly configured to drive the first arc-shaped hub portion and the second arc-shaped hub portion to move into the vehicle body.

[0119] For example, as shown in FIG. 2, when the stowable steering wheel is in the second mode, the second connecting portion drives the second arc-shaped hub portion to rotate in the clockwise direction to the second plane, then the first connecting portion drives the first arc-shaped hub portion to rotate in the clockwise direction to the third plane, and finally the upper rim, the lower rim and the central portion (the central portion is optional, i.e., the central portion can not exist) can be driven by the electric driving assembly to move into the vehicle body. Figure 3

[0120] ​Optionally, in the process of storing the steering wheel, in order to avoid the first arc-shaped hub portion from hurting the driver when rotating, after the second arc-shaped hub portion is rotated to the second plane, the first arc-shaped hub portion and the second arc-shaped hub portion can be retracted close to the vehicle body, and then the first arc-shaped hub portion is rotated to the third plane along the first direction.

[0121] In the embodiments of the present application, in the process of storing the steering wheel, the second arc-shaped hub portion and the first arc-shaped hub portion can be rotated to the second plane and the third plane, respectively, which can realize the convenience of storing the steering wheel and improve the comfort of the driver during the storage process.

[0122] The first connecting portion and the second connecting portion will be described in detail below. Figure 4 and Figure 5 The first connecting portion and the second connecting portion will be described in detail below.

[0123] In a possible implementation manner, as shown in Figure 4 the first connecting portion includes a first connecting shaft and a second connecting shaft, the first connecting shaft and the second connecting shaft are on the same straight line, and the first connecting shaft and the second connecting shaft are used to realize the first rotating shaft; the second connecting portion includes a third connecting shaft, a first connecting rod, a second connecting rod, a third connecting rod, and a fourth connecting rod, the third connecting shaft is used to realize the second rotating shaft, wherein the first end portion of the third connecting shaft is connected to the first end portion of the second connecting rod through the first connecting rod, the second end portion of the third connecting shaft is connected to the first end portion of the fourth connecting rod through the third connecting rod, the second connecting rod and the fourth connecting rod are on the same straight line and are parallel to the third connecting shaft, and the second end portion of the second connecting rod and the second end portion of the fourth connecting rod are connected to the two ends of the second arc-shaped hub portion, respectively.

[0124] In the embodiments of the present application, the first connecting portion can realize the first rotating shaft through the first connecting shaft and the second connecting shaft, and the second connecting portion can realize the second rotating shaft through the third connecting shaft, which can ensure that the first arc-shaped hub portion and the second arc-shaped hub portion do not interfere with each other during the storage process, and the structure of the lower rim can be strengthened through the first connecting rod to the fourth connecting rod, which is conducive to better storage of the second arc-shaped hub portion.

[0125] In addition to the connecting shaft form, the first connecting portion and the second connecting portion can also be in the form of a gear.

[0126] In a possible implementation manner, the first connecting portion is a first gear, the first gear is used to realize the first rotating shaft, and the second connecting portion is a second gear, the second gear is used to realize the second rotating shaft.

[0127] Exemplarily, as shown in Figure 5As shown in (a) of FIG. 1, the first gear can be connected to the first end of the first arc-shaped hub portion, the second gear can be connected to the first end of the second arc-shaped hub portion, or, as shown in (b) of FIG. 1, one first gear can be connected to both ends of the first arc-shaped hub portion, and one second gear can be connected to both ends of the second arc-shaped hub portion. Figure 5

[0128] Optionally, the first gear and the second gear can also be connected with a clutch, a gear box and a motor, so as to realize rotation and stop of the first gear and the second gear.

[0129] In the embodiment, the first connecting portion can be a first gear, and the second connecting portion can be a second gear. Such a processing manner can simplify the structure of the first connecting portion and the second connecting portion, and is beneficial to guarantee the same-direction rotation of the first arc-shaped hub portion and the second arc-shaped hub portion.

[0130] In one embodiment, a stowable steering wheel is provided, which can be applied to a vehicle. The stowable steering wheel comprises: an upper rim, the upper rim comprising a third arc-shaped hub portion and a third connecting portion, the third arc-shaped hub portion being connected to the third connecting portion, the third arc-shaped hub portion having a third rotation axis, and the third arc-shaped hub portion being rotatable along the third rotation axis; and a lower rim, the lower rim comprising a fourth arc-shaped hub portion and a fourth connecting portion, the fourth arc-shaped hub portion being connected to the fourth connecting portion, the fourth arc-shaped hub portion having a fourth rotation axis, and the fourth arc-shaped hub portion being rotatable along the fourth rotation axis. When the stowable steering wheel is in a fourth mode, the third arc-shaped hub portion and the fourth arc-shaped hub portion have different diameters.

[0131] The fourth mode can be a stowed mode of the stowable steering wheel, and the fourth mode can correspond to a parking mode of the vehicle. That is, after the vehicle is started in the parking mode, the stowable steering wheel is in the fourth mode.

[0132] Optionally, the third connecting portion and the fourth connecting portion can be gears or connecting shafts.

[0133] Optionally, the stowable steering wheel further comprises a central portion, the central portion being mounted on a steering column of the vehicle, and the third connecting portion and the fourth connecting portion can be located in the central portion.

[0134] Specifically, as shown in FIG. 2, the third arc-shaped hub portion and the fourth arc-shaped hub portion can be connected to the third connecting portion and the fourth connecting portion through a plurality of gears. Figure 6 ​As shown, the stowable steering wheel can include an upper rim and a lower rim. The upper rim includes a third arc-shaped hub portion and a third connecting portion, and the two ends of the third arc-shaped hub portion and the two ends of the third connecting portion are connected. The lower rim includes a fourth arc-shaped hub portion and a fourth connecting portion, and the two ends of the fourth arc-shaped hub portion and the two ends of the fourth connecting portion are connected. The third arc-shaped hub portion and the fourth arc-shaped hub portion can be the part that the driver holds with his hand to rotate the steering wheel. Through the third arc-shaped hub portion and the fourth arc-shaped hub portion, the driver can easily control the vehicle to realize the operation of turning, steering, and adjusting the driving direction of the vehicle. Optionally, the stowable steering wheel further includes a central portion mounted on the steering column of the vehicle. Part or all of the third connecting portion and the fourth connecting portion can be located in the central portion. Function buttons such as audio control buttons, cruise control buttons, and telephone answering buttons can be arranged on the central portion. The arrangement of these function buttons can make it more convenient for the driver to operate various functions on the vehicle during driving, thereby improving the convenience and comfort of driving. On the other hand, an airbag cover can be arranged on the central portion. The safety airbag in the airbag cover can quickly inflate and deploy when the vehicle collides, providing protection for the driver and reducing the harm caused by the collision.

[0135] In the embodiments of the present application, when the stowable steering wheel is in the stowed state, the diameters of the third arc-shaped hub portion and the fourth arc-shaped hub portion are different. Such arrangement can facilitate better stowage of the third arc-shaped hub portion and the fourth arc-shaped hub portion, thereby effectively saving space inside the vehicle and improving the comfort of the driver when the stowable steering wheel is in the stowed state.

[0136] In a possible implementation, the third rotating shaft and the fourth rotating shaft are on the same straight line.

[0137] Exemplarily, as shown, Figure 7 The third connecting portion includes a fourth connecting shaft and a fifth connecting shaft, and the fourth connecting shaft and the fifth connecting shaft are on the same straight line, and the fourth connecting shaft and the fifth connecting shaft are used to realize the third rotating shaft. The fourth connecting portion includes a sixth connecting shaft, a fifth connecting rod, a sixth connecting rod, a seventh connecting rod, and an eighth connecting rod. The sixth connecting shaft is used to realize the fourth rotating shaft. The first end of the sixth connecting shaft is connected to the first end of the sixth connecting rod through the fifth connecting rod, the second end of the sixth connecting shaft is connected to the first end of the eighth connecting rod through the seventh connecting rod, the sixth connecting rod and the eighth connecting rod are on the same straight line and are parallel to the sixth connecting shaft, and the second end of the sixth connecting rod and the second end of the eighth connecting rod are connected to the two ends of the fourth arc-shaped hub portion, respectively.

[0138] In the embodiments of the present application, the first rotating shaft can be realized by the fourth connecting shaft and the fifth connecting shaft, the second rotating shaft can be realized by the sixth connecting shaft, and the diameters of the third arc-shaped hub portion and the fourth arc-shaped hub portion are different when the steerable wheel is in the fourth mode. Such a design can ensure that the third arc-shaped hub portion and the fourth arc-shaped hub portion do not interfere with each other during storage, and the structure of the lower rim can be strengthened by the fifth connecting rod to the eighth connecting rod, which is beneficial to better storage of the fourth arc-shaped hub portion.

[0139] In a possible implementation, as shown in (a) of Figure 8 , the sixth connecting shaft comprises a first connecting segment and a second connecting segment; when the steerable wheel is in the third mode, the first connecting segment and the second connecting segment are separated, so that the length of the fourth connecting portion parallel to the direction of the sixth connecting shaft is a first length; as shown in (b) of Figure 8 , when the steerable wheel is in the fourth mode, the first connecting segment and the second connecting segment are connected, so that the length of the fourth connecting portion parallel to the direction of the sixth connecting shaft is a second length, and the second length is less than the first length.

[0140] The third mode can be a non-stored mode of the steerable wheel, and the third mode can correspond to a driving mode of the vehicle, that is, the steerable wheel is in the third mode when the vehicle is driving or the driving mode is turned on.

[0141] In a possible implementation, as shown in Figure 9 , the fourth arc-shaped hub portion is provided with a first telescopic portion; when the steerable wheel is in the third mode, the first telescopic portion is in an extended state, so that the diameter of the fourth arc-shaped hub portion is a third length, and when the steerable wheel is in the fourth mode, the first telescopic portion is in a compressed state, so that the diameter of the fourth arc-shaped hub portion is a fourth length, and the fourth length is less than the third length.

[0142] Optionally, the difference between the first length and the second length is equal to the difference between the third length and the fourth length.

[0143] Alternatively, the first telescopic portion can not be provided, and a second telescopic portion can be provided on the third arc-shaped hub portion; when the steerable wheel is in the third mode, the second telescopic portion is in a compressed state, the diameter of the third arc-shaped hub portion is a fifth length, and when the steerable wheel is in the fourth mode, the second telescopic portion is in an extended state, the diameter of the third arc-shaped hub portion is a sixth length, and the sixth length is greater than the fifth length. Such a design can also make the third arc-shaped hub portion and the fourth arc-shaped hub portion of the steerable wheel in the storage state be in the same plane.

[0144] Alternatively, the first telescopic part can not be provided, and the third arc-shaped hub part has a seventh length in diameter, and the fourth arc-shaped hub part has an eighth length in diameter, the eighth length being smaller than the seventh length. In this way, the upper rim can always accommodate the lower rim.

[0145] In the embodiments of the present application, when the stowable steering wheel is in the fourth mode, the first connecting section and the second connecting section are connected, and / or the first telescopic part is in the compressed state, so as to reduce the diameter of the fourth arc-shaped hub part, thereby reducing the lower rim. In this way, when the stowable steering wheel is in the stowed state, the third arc-shaped hub part and the fourth arc-shaped hub part are in the same plane, thereby effectively saving the space in the vehicle.

[0146] In one possible implementation, when the stowable steering wheel is in the third mode, the third arc-shaped hub part and the fourth arc-shaped hub part are in the fourth plane; when the stowable steering wheel is in the fourth mode, the fourth connecting part is used to drive the fourth arc-shaped hub part to rotate in the first direction to the fifth plane, and the third connecting part is used to drive the third arc-shaped hub part to rotate in the first direction to the fifth plane, the fifth plane and the first plane forming a third preset angle.

[0147] Optionally, the first direction can be the clockwise direction or the counterclockwise direction.

[0148] Optionally, the stowable steering wheel further comprises an electric driving assembly configured to drive the third arc-shaped hub part and the fourth arc-shaped hub part to move into the vehicle body.

[0149] For example, as shown in Figure 10 when the stowable steering wheel is in the fourth mode, the diameter of the fourth arc-shaped hub part is first shortened through the first connecting section, the second connecting section, and the first telescopic part, then the fourth connecting part drives the fourth arc-shaped hub part to rotate in the clockwise direction to the fifth plane, the third connecting part drives the third arc-shaped hub part to rotate in the clockwise direction to the fifth plane, so that the upper rim and the lower rim coincide, and finally, the upper rim, the lower rim, and the central part (the central part is optional, i.e., the central part can not exist) can be driven by the electric driving assembly to move into the vehicle body.

[0150] Optionally, during the stowing of the steering wheel, in order to avoid the third arc-shaped hub part from hurting the driver during rotation, after the fourth arc-shaped hub part is rotated to the fifth plane, the third arc-shaped hub part, the fourth arc-shaped hub part, and the central part can be retracted close to the vehicle body, and then the third arc-shaped hub part is rotated to the fifth plane in the first direction.

[0151] Alternatively, in the above storage process, the upper rim and the lower rim can also not coincide, that is, when the steerable wheel is in the fourth mode, the diameter of the fourth arc-shaped hub portion can be shortened through the first connecting section, the second connecting section and the first telescopic portion first, then the fourth connecting portion drives the fourth arc-shaped hub portion to rotate along the clockwise sixth plane, the third connecting portion drives the third arc-shaped hub portion to rotate along the clockwise direction to the seventh plane, and finally, the upper rim, the lower rim and the central portion (the central portion is optional, that is, the central portion can not exist) can be moved into the vehicle body under the driving of the electric driving assembly. The angle between the sixth plane and the fourth plane is a fourth preset value, the angle between the seventh plane and the fourth plane is a fifth preset value, and the fourth preset value and the fifth preset value are different.

[0152] In the embodiments of the present application, in the storage process of the steerable wheel, the third arc-shaped hub portion and the fourth arc-shaped hub portion can be rotated in the same direction to the fifth plane, so that the convenience of the steerable wheel in the storage process can be realized, thereby further improving the comfort of the driver in the storage state of the steerable wheel.

[0153] In addition to being arranged in the form of the above-mentioned connecting shaft, the third connecting portion and the fourth connecting portion can also be arranged in the form of a gear.

[0154] In a possible implementation manner, the third connecting portion is a third gear, and the third gear is used to realize a third rotation shaft. The fourth connecting portion is a fourth gear, and the fourth gear is used to realize a fourth rotation shaft.

[0155] Optionally, the third gear can be connected to the first end portion of the third arc-shaped hub portion, and the fourth gear can be connected to the first end portion of the fourth arc-shaped hub portion, or both end portions of the third arc-shaped hub portion can be connected to one third gear, and both end portions of the fourth arc-shaped hub portion can be connected to one fourth gear.

[0156] Optionally, the third gear and the fourth gear can also be connected with a clutch, a gear box and a motor, so as to realize the rotation and stop of the third gear and the fourth gear.

[0157] In the embodiments of the present application, the third connecting portion can be arranged as a third gear, and the fourth connecting portion can be arranged as a fourth gear. Such a processing manner can simplify the structure of the third connecting portion and the fourth connecting portion, and is conducive to ensuring the same direction rotation of the third arc-shaped hub portion and the fourth arc-shaped hub portion.

[0158] The above is combined Figures 2 to 11 Two steerable wheels are exemplarily described. The present application also provides a steering wheel 10 which can be applied to Figure 1 the vehicle shown in the drawings, Figures 2 to 10 The steering wheel shown in the drawings can be understood as an extension or deformation of the steering wheel 10.

[0159] For example, the steering wheel 10 may include an upper hub portion 100, a lower hub portion 200, and a central portion 300; the steering wheel 10 may have a driving mode and a storage mode. In driving mode, the upper hub portion 100 and the lower hub portion 200 may be closed to form a ring structure, with the upper hub portion 100 and the lower hub portion 200 positioned on the upper and lower sides of the ring structure, respectively; the ring structure is available for the user to grip and may surround the central portion. In storage mode, both the upper and lower hub portions may be stored behind and below the central portion.

[0160] In one embodiment, with Figure 2 and Figure 3 Taking the retractable steering wheel shown as an example, combined with Figure 11 This is an example illustration.

[0161] exist Figure 11 In this configuration, the first arc-shaped wheel hub portion can correspond to the upper wheel hub portion 100 of the steering wheel 10, and the second arc-shaped wheel hub portion can correspond to the lower wheel hub portion 200; the first mode can correspond to the driving mode, and the second mode can correspond to the storage mode. Additionally, Figure 11 (a) in the text can be understood as, in Figure 2 Based on this, it emphasizes the shape of the ring structure formed by the first arc-shaped hub and the second arc-shaped hub when the steering wheel is in the first mode; Figure 11 (b) in the text can be understood as, in Figure 3 Based on this, the positional relationship between the first arc-shaped hub, the second arc-shaped hub, and the central part when the steering wheel is in the second mode is emphasized.

[0162] like Figure 11 As shown in (a), in the first mode, the first and second arc-shaped hub portions of the retractable steering wheel can be joined to form a ring structure surrounding the central portion. Figure 11 As shown in (b), when the steering wheel is in the second mode, the first arc-shaped hub and the second arc-shaped hub can be completely retracted to the lower rear of the central part.

[0163] In yet another embodiment, with Figure 6 and Figure 10 Taking the retractable steering wheel shown as an example, combined with Figure 12 This is an example illustration.

[0164] exist Figure 12 In the middle, the third arc-shaped wheel hub can correspond to the upper wheel hub 100 of the steering wheel 10, and the fourth arc-shaped wheel hub can correspond to the lower wheel hub 200; the third mode can correspond to the driving mode, and the fourth mode can correspond to the storage mode. Additionally, Figure 12 (a) in the text can be understood as, inFigure 6 Based on this, it emphasizes the shape of the ring structure formed by the third and fourth arc-shaped hubs when the steering wheel is in the third mode; Figure 12 (b) in the text can be understood as, in Figure 10 Based on this, the positional relationship between the third arc-shaped hub, the fourth arc-shaped hub, and the central part when the steering wheel is in the fourth mode is emphasized.

[0165] like Figure 12 As shown in (a), in the third mode, the third and fourth arc-shaped hub portions of the retractable steering wheel can be joined together to form a ring structure surrounding the central portion. Figure 12 As shown in (b), when the steering wheel is in the fourth mode, the third and fourth arc-shaped hub sections can be completely retracted into the lower rear of the central section.

[0166] For the steering wheel 10, the specific shape of the annular structure formed by the upper hub portion 100 and the lower hub portion 200 can be determined by the shapes of the upper hub portion 100 and the lower hub portion 200 in the steering wheel 10. This annular structure can be circular, or it can be other regular or irregular annular shapes. The following combines... Figure 13 This is an example illustration.

[0167] For example, Figure 13 These are schematic diagrams of several ring structures provided in the embodiments of this application.

[0168] In one embodiment, the upper hub portion 100 and the lower hub portion 200 are two independent components, assuming their specific shapes are as follows: Figure 13 As shown in (a) of the diagram; the frames of the upper hub portion 100 and the lower hub portion 200 can be arc-shaped, and these two arcs can have the same diameter. In this case, the annular structure formed by the upper hub portion 100 and the lower hub portion 200 can have the following shape: Figure 13 As shown in (b) of the diagram.

[0169] In another embodiment, it is assumed that the specific shape of the upper hub portion 100 remains as follows Figure 13 As shown in (a) of the diagram, the frame of the lower hub portion 200 can be irregularly shaped. For example, the middle portion of the frame of the lower hub portion 200 can be replaced by a line segment instead of an arc. In this case, the annular structure formed by the upper hub portion 100 and the lower hub portion 200 can have the following shape: Figure 13 As shown in (c) in the figure.

[0170] In another embodiment, if the middle portion of the upper hub 100's frame is also replaced by a line segment instead of an arc, the corresponding annular structure formed by the upper hub portion 100 and the lower hub portion 200 can have the following shape:Figure 13 As shown in (d) in the figure.

[0171] In yet another embodiment, Figure 2 The annular structure formed by the first and second arc-shaped hub portions can have a shape like... Figure 13 As shown in (b) above. Similarly, Figure 6 The ring structure formed by the third and fourth hub sections can be shaped as follows: Figure 13 As shown in (b) of the diagram.

[0172] For example, the central portion 300 can be connected to the steering column. In driving mode, the user can hold the ring structure formed by the upper hub 100 and the lower hub 200; when the user rotates the ring structure, the central portion 300 will drive the steering column to rotate, thereby enabling the user to control the steering of the vehicle; in this way, the basic usage requirements of the steering wheel can be met.

[0173] For example, Figure 14 This is a schematic diagram of the steering wheel 10 provided in this application embodiment in different modes.

[0174] exist Figure 14 In the middle, assuming that the upper hub portion 100 and the lower hub portion 200 adopt Figure 13 The shape shown in (a) is shown in the image. Figure 14 (a) in the text can be understood as a front view of the steering wheel 10 in driving mode; Figure 14 (b) in the text can be understood as a front view of the steering wheel 10 in storage mode.

[0175] The "front view" of the steering wheel can be understood as the view observed by a standing user holding the steering wheel with both hands, directly facing it, when the steering wheel is in a neutral position. Based on this observation method, the directions represented by "left / right / front / back / up / down" of the steering wheel are explained. "Left" can represent the direction to the user's left hand; "right" can represent the direction to the user's right hand; "front" or "direction" can represent the side facing the user; "back" or "rear" can represent the side away from the user; "up" can represent the position of the user's head; and "down" can represent the position of the user's feet.

[0176] Reference Figure 14 In (a) of the driving mode, the user can rotate the steering wheel 10 along axis 11; correspondingly, the steering wheel 10 can rotate the steering column located behind it. This steering column can be positioned along axis 11, and in… Figure 14 Not shown in the image.

[0177] Reference Figure 14In the (b) in the storage mode, the upper and lower hub portions can be stored at the lower rear of the central portion.

[0178] In actual scenarios, the steering column is usually arranged obliquely, and in the height direction of the vehicle, the instrument table of the vehicle can be arranged above the steering column, and sufficient leg space can be provided below the instrument table for the user. If the steering wheel is stored in other ways, such as being stored in the instrument table, not only does the steering column need to be arranged in the instrument table (for example, the steering column can need to be extended horizontally from the instrument table), but also a storage space for the steering wheel needs to be reserved in the instrument table; because the instrument screen, air outlet, etc. usually occupy a large space in the instrument table, it is often difficult to successfully arrange the storage space for the steering wheel in the instrument table. Even if the size of the steering wheel is reduced to successfully arrange the storage space, on the one hand, the steering wheel is too small to provide a poor user experience, and on the other hand, the design and structure of the related components such as the steering column in the steering system need to be adjusted on a large scale, which makes it difficult for this way to have good universality for different vehicle models, thereby resulting in high costs.

[0179] In the embodiments of the present application, in the storage mode, the upper hub portion 100 and the lower hub portion 200 can be stored at the lower rear of the central portion 300, and the existing leg space in the vehicle can be fully utilized to store the steering wheel. Especially in the case where the steering column has a telescopic function, after the steering column is shortened, the stored steering wheel can effectively avoid interference with the instrument table. Compared with the scheme of storing the steering wheel in the instrument table, the steering column and other related components in the steering system do not need to be adjusted on a large scale, have high universality for different vehicle models, and thus can store the steering wheel at a low cost and system complexity. Moreover, since the upper hub portion and the lower hub portion are independent components, when the annular structure has a large radial dimension, this storage method can also ensure good storage effect.

[0180] In some possible implementations, the steering wheel 10 can further include a fifth connecting portion 400 and a sixth connecting portion 500. The upper hub 100 can be connected to the central portion 300 through the fifth connecting portion 400, and the fifth connecting portion 400 can include a rotating shaft arranged along a first axis 401, and the upper hub 100 can rotate relative to the central portion 300 along the first axis 401. The lower hub 200 can be connected to the central portion 300 through the sixth connecting portion 500, and the sixth connecting portion 500 can include a rotating shaft arranged along a second axis 501, and the lower hub 200 can rotate relative to the central portion 300 along the second axis 501.

[0181] In one example, with reference to Figure 2The first connecting portion in the stowable steering wheel can correspond to the fifth connecting portion 400; the second connecting portion in the steering wheel can correspond to the sixth connecting portion 500. For example, when the first connecting portion and the second connecting portion adopt the structure as shown in Figure 4 The axis of the first connecting shaft and the second connecting shaft can correspond to the first axis 401; the axis of the third connecting shaft can correspond to the second axis 501. For another example, when the first connecting portion and the second connecting portion adopt the structure as shown in Figure 5 The axis of the first gear can correspond to the first axis 401; the axis of the second gear can correspond to the second axis 501. In this example, the second axis 501 can be parallel to the first axis 401, and the second axis 501 can be located above the first axis 401.

[0182] In another example, referring to the stowable steering wheel as shown in Figure 6 The third connecting portion in the stowable steering wheel can correspond to the fifth connecting portion 400; the fourth connecting portion in the steering wheel can correspond to the sixth connecting portion 500. For example, when the third connecting portion and the fourth connecting portion adopt the structure as shown in Figure 7 The axis of the fourth connecting shaft and the fifth connecting shaft can correspond to the first axis 401; the axis of the sixth connecting shaft can correspond to the second axis 501. For another example, when the fourth connecting shaft, the fifth connecting shaft and the sixth connecting shaft are arranged along the same axis, the axis can correspond to both the first axis 401 and the second axis 501.

[0183] In another example, the fifth connecting portion 400 and / or the sixth connecting portion 500 can be arranged on the back of the central portion 300 for the sake of aesthetic appearance, so as to be hidden by the central portion; or part or all of the fifth connecting portion 400 and / or the sixth connecting portion 500 can be arranged in the central portion 300. In this case, the fifth connecting portion 400 and the sixth connecting portion 500 can not be observed in the front view of the steering wheel 10, as shown in Figure 14

[0184] In some possible implementations, when the steering wheel 10 is in the driving mode, the upper hub portion 100 and the lower hub portion 200 can be in the eighth plane; when the steering wheel 10 is in the stowed mode, the fifth connecting portion 400 can be used to drive the upper hub portion 100 to rotate in the first direction to the ninth plane, and the sixth connecting portion 500 can be used to drive the lower hub portion 200 to rotate in the first direction to the tenth plane.

[0185] In one embodiment, referring to Figure 3 ​The storable steering wheel shown, when the steering wheel is switched from the first mode to the second mode, the second connecting part can drive the second arc-shaped hub part to rotate to the second plane in the clockwise direction, and the first connecting part can drive the first arc-shaped hub part to rotate to the third plane in the clockwise direction. In this example, the second plane can correspond to the tenth plane described above, and the third plane can correspond to the ninth plane described above. Figure 3 The clockwise direction in the above can correspond to the first direction described above. Accordingly, the included angle between the eighth plane and the ninth plane can be a first preset value; the included angle between the eighth plane and the tenth plane can be a second preset value.

[0186] In another embodiment, referring to Figure 10 The storable steering wheel shown, when the steering wheel is in the fourth mode, the fourth connecting part can drive the fourth arc-shaped hub part to rotate to the fifth plane in the clockwise direction, and the third connecting part can drive the third arc-shaped hub part to rotate to the fifth plane in the clockwise direction. In this example, the fifth plane can correspond to both the ninth plane and the tenth plane.

[0187] In another embodiment, taking the steering wheel shown in Figure 14 As an example, the eighth plane, the ninth plane, and the tenth plane described above are exemplarily explained in combination with Figure 15

[0188] Exemplarily, Figure 15 is another schematic diagram of the steering wheel 10 in different modes provided by the embodiments of the present application.

[0189] In Figure 15 , it is assumed that the shapes of the upper hub part 100, the lower hub part 200, and the central part 300 are the same as Figure 14 , and it is also assumed that the second axis 501 is parallel to the first axis 401, and the second axis 501 is above the first axis 401. That is, in Figure 15 , the storage mode of the steering wheel 10 can be the same as the storage mode of the steering wheel shown in Figure 2 Figure 15 In (a) of Figure 15 , the side view of the steering wheel 10 in the driving mode can be understood as;

[0190] Referring to Figure 15 (a), in the driving mode, the upper hub part 100 can be in the plane 101, and the lower hub part 200 can be in the plane 201.

[0191] In an example, the plane 101 can be parallel to the plane 201.

[0192] ​​In yet another example, the plane 101 can be inclined to the plane 201; correspondingly, the included angle between the plane 101 and the plane 201 can be less than a certain angle threshold, such as 5 degrees, to avoid excessive bending of the annular structure at the transition between the upper and lower hub portions.

[0193] In yet another example, the plane 101 and the plane 201 can be the same plane. In this case, the plane 101 and the plane 201 can correspond to the eighth plane described above.

[0194] In the embodiments of the present application, for the annular structure formed by the upper hub portion 100 and the lower hub portion 200, when the plane 101 and the plane 201 are the same plane, the annular structure can not have a step surface or an included angle at the transition between the upper and lower hub portions. Correspondingly, even if the driver holds the annular structure at this transition, discomfort will not be caused by the step surface or the included angle, thereby improving the driver's holding experience.

[0195] When switched to the storage mode, the upper hub portion 100 can be rotated clockwise from the plane 101 to the plane 102 along the first axis 401; the lower hub portion 200 can be rotated clockwise from the plane 101 to the plane 202 along the second axis 501. Correspondingly, in the storage mode, the upper hub portion 100 can be in the plane 102, and the lower hub portion 200 can be in the plane 202, as shown in (b) of FIG. 1. Figure 15 The plane 102 can correspond to the ninth plane described above, and the plane 202 can correspond to the tenth plane described above.

[0196] In an example, an included angle can exist between the plane 102 and the plane 202.

[0197] In the case where an included angle exists between the plane 102 and the plane 202, when the steering wheel is in the storage mode, if the steering wheel adopts a conventional shape, an included angle / warping can exist between the upper and lower hub portions, which will require a larger accommodation space to accommodate the upper and lower hub portions; if the steering wheel adopts a special shape or needs to be adapted to other components (such as part of the trim panel of the instrument panel) around, a better appearance effect can be provided.

[0198] In yet another example, the plane 102 and the plane 202 can be parallel.

[0199] In actual design, the arrangement space around the instrument panel is often cramped. In the embodiments of the present application, in the storage mode, the upper and lower hub portions are stored in two parallel planes, which is beneficial to reduce the storage space required by the steering wheel and facilitate the successful arrangement of the steering wheel with storage function on the vehicle.

[0200] Exemplarily, the central portion 300 can include an intermediate support 320. For example, with reference to Figure 15In (b) of FIG. 3, the central portion 300 can include a shielding structure 310 and an intermediate support 320. The shielding structure 310 can be disposed on the front side of the steering wheel, and the intermediate support 320 can be disposed on the back side of the steering wheel.

[0201] In one possible design, the shielding structure 310 and the intermediate support 320 can be separate parts. For example, the two parts can enclose a cavity, and some or all of the fifth connecting portion 400 and / or the sixth connecting portion 500 can be disposed in the cavity. For another example, an airbag can be disposed in the cavity; when the airbag is triggered, the shielding structure 310 can be ejected by the airbag. For yet another example, the intermediate support 320 can serve to fix and support various parts disposed on the steering wheel, such as an airbag, a function button, and the like.

[0202] In some possible implementations, the rotation shaft included in the fifth connecting portion 400 and disposed along the first axis 401 can include a seventh connecting shaft and an eighth connecting shaft, which can be disposed on opposite sides of the central portion 300.

[0203] The following exemplary description is made with reference to the stowable steering wheel shown in Figure 4 and Figure 7 It should be understood that, Figure 4 and Figure 7 The central portion of the steering wheel is not shown in

[0204] Referring to Figure 4 , one end of the first connecting shaft can be connected to the left side of the first arc-shaped hub portion, and one end of the second connecting shaft can be connected to the right side of the first arc-shaped hub portion. Correspondingly, the other end of the first connecting shaft can be connected to the central portion, and the other end of the second connecting shaft can be connected to the intermediate support. In this example, since the first connecting shaft and the second connecting shaft can constitute the first rotation shaft, one of them can correspond to the seventh connecting shaft, and the other can correspond to the eighth connecting shaft.

[0205] Referring to Figure 7 , the fourth connecting shaft and the fifth connecting shaft are connected to the third arc-shaped hub portion and can constitute the third rotation shaft; correspondingly, one of the two connecting shafts can correspond to the seventh connecting shaft, and the other can correspond to the eighth connecting shaft.

[0206] Similarly, the rotation shaft included in the sixth connecting portion 500 and disposed along the second axis 501 can include a ninth connecting shaft and a tenth connecting shaft. The ninth connecting shaft and the tenth connecting shaft can be disposed on opposite sides of the central portion.

[0207] In the embodiments of the present application, the seventh connecting shaft and the eighth connecting shaft arranged along the first axis 401 are arranged on the two sides of the intermediate support, so that the two connecting shafts can be arranged in a symmetrical manner, which is beneficial to the weight balance of the left and right sides of the steering wheel, so that the steering wheel can be kept in a neutral position when it is not turned by the user, thereby avoiding unintended turning / yawing of the vehicle. Moreover, arranging the seventh connecting shaft and the eighth connecting shaft on the two sides of the central part is also beneficial to reducing the space occupation of these connecting shafts on the central part.

[0208] The following is an example of the steering wheel shown in Figure 15 , combined with Figure 16 , the seventh connecting shaft to the tenth connecting shaft are exemplarily described.

[0209] Exemplarily, Figure 16 is a schematic diagram of the connection relationship between the upper and lower hub parts and the central part 300 provided by the embodiments of the present application. In Figure 16 , it is assumed that the shapes of the upper hub part 100, the lower hub part 200 and the central part 300, and the relative positional relationship between the first axis 401 and the second axis 501, are the same as Figure 15 . In addition, in Figure 16 , the shielding structure 310 in the central part 300 is not shown.

[0210] Referring to (a) in Figure 16 , the connecting shafts 410 and 420 can be arranged along the axis 401. The connecting shaft 410 can be arranged on the left side of the intermediate support 320; one end of the connecting shaft 410 can be hinged to the intermediate support 320, and the other end of the connecting shaft 410 can be connected to the upper hub part 100, and the connection position can be near the left inner wall of the upper hub part 100. The connecting shaft 420 can be arranged on the right side of the intermediate support 320; one end of the connecting shaft 420 can be hinged to the intermediate support 320, and the other end of the connecting shaft 420 can be connected to the upper hub part 100, and the connection position can be near the right inner wall of the upper hub part 100.

[0211] Similarly, the connecting shafts 510 and 520 can be arranged along the axis 501. The connecting shaft 510 can be arranged on the left side of the intermediate support 320; one end of the connecting shaft 510 can be hinged to the intermediate support 320, and the other end of the connecting shaft 510 can be connected to the lower hub part 200, and the connection position can be near the left inner wall of the lower hub part 200. The connecting shaft 520 can be arranged on the right side of the intermediate support 320; one end of the connecting shaft 520 can be hinged to the intermediate support 320, and the other end of the connecting shaft 520 can be connected to the lower hub part 200, and the connection position can be near the right inner wall of the lower hub part 200.

[0212] In one example, it is assumed that the seventh connecting shaft and the ninth connecting shaft are on the same side of the steering wheel. For example, the connecting shaft 410 can correspond to the seventh connecting shaft, and the connecting shaft 510 can correspond to the ninth connecting shaft; correspondingly, the connecting shaft 420 can correspond to the eighth connecting shaft, and the connecting shaft 520 can correspond to the tenth connecting shaft.

[0213] Exemplarily, in the cross-sectional view at position A-A in (a) of Figure 16 , it can be shown as in (b) of Figure 16 .

[0214] Referring to (b) of Figure 16 , when switching to the storage mode, the upper and lower hub portions can be controlled to rotate clockwise around the corresponding axis (401, 501) from the current posture. When switching to the driving mode again, the upper and lower hub portions can be controlled to rotate counterclockwise around the corresponding axis to recover to the posture shown in (b) of Figure 16 .

[0215] Since the corresponding rotation axis 501 of the lower hub portion 200 is above the axis 401, during the rotation of the upper and lower hub portions around the corresponding axis (401, 501), no interference can occur between the upper and lower hub portions, thereby achieving the storage effect shown in Figure 3 .

[0216] In a specific implementation, the axis 501 can be arranged directly above the axis 401, or the axis 501 can also be arranged above and behind the axis 401. Hereinafter, taking the steering wheel shown in Figure 16 as an example, the positional relationship between the axes 401 and 501 is exemplarily described in combination with Figure 17 . In Figure 17 , the connecting shafts 410, 420, 510, and 520 can correspond to the seventh connecting shaft, the eighth connecting shaft, the ninth connecting shaft, and the tenth connecting shaft, respectively.

[0217] Exemplarily, Figure 17 is a schematic diagram of the relative positional relationship between the axes 401 and 501 provided by the embodiments of the present application.

[0218] Among them, Figure 17 (a) in (a) adopts the same perspective as (b) in Figure 16 ; in order to more clearly reflect the positional relationship between the upper and lower hub portions and the connecting shafts 420 and 520, the intermediate support 320 is not shown in (a) of Figure 17 . Moreover, since the connecting shafts 420 and 520 are arranged along the axes 401 and 501 respectively, in (b) to (e) of Figure 17 , the positions of the connecting shafts 420 and 520 respectively represent the arrangement positions of the axes 401 and 501.

[0219] Referring to (a) of Figure 17 , as the connecting shaft 520 is arranged above the connecting shaft 420, in order to connect with the connecting shaft 520, the lower hub portion 100 can be provided with a structure for avoiding interference near the connecting shaft 420, which can prevent the lower hub portion 200 and the connecting shaft 420 from interfering with each other when the steering wheel is in the driving mode.

[0220] Referring to (b) of Figure 17 , when the connecting shaft 520 is arranged directly above the connecting shaft 420, the lower hub portion 200 can be provided with a larger structure for avoiding interference; accordingly, in the thickness direction of the steering wheel (i.e., the front-rear direction of the steering wheel), the upper and lower hub portions can have a larger warping near the connecting shaft 420.

[0221] Referring to (c) of Figure 17 , the connecting shaft 520 can be arranged above and behind the connecting shaft 420, and as the steering wheel has a certain thickness, the warping can be eliminated by adjusting the thickness of the lower hub portion 200 at the structure for avoiding interference. For example, when the connecting shafts 520 and 420 are arranged in this way, the shape of the upper and lower hub portions can be as shown in (a) of Figure 17 .

[0222] Referring to (d) of Figure 17 , when the relative distance between the connecting shafts 420 and 520 in the thickness direction of the steering wheel is too large, the steering wheel can need a larger thickness to completely hide the structure for avoiding interference from the side. For the sake of modeling, the structure of the lower hub portion 200 can be arranged to have a support extending rearward of the steering wheel based on the lower half of the annular structure; the support can extend from the annular structure to the connecting shaft 520.

[0223] In some design manners, referring to (e) of Figure 17 , the connecting shaft 520 can also be arranged directly behind the connecting shaft 420.

[0224] When the relative distance between the connecting shafts 420 and 520 in the thickness direction of the steering wheel is too large, if the lower hub portion contains a support extending from the annular structure to the connecting shaft 520, the lower hub portion can appear as a cantilever beam in the driving mode, which can result in poor strength.

[0225] In some embodiments, the distance between the connecting shafts 420 and 520 in the thickness direction of the steering wheel can be less than or equal to a certain threshold value to ensure the strength of the lower hub portion. For example, 4 cm or 5 cm.

[0226] The above is in combination with Figure 16 and 17In the embodiments of the steering wheel 10, the axis 401 and the axis 501 are parallel to each other, and the relative positional relationship between the axis 401 and the axis 501 is exemplarily illustrated.

[0227] In other embodiments, the axis 401 and the axis 501 can be the same axis. Assuming that the seventh connecting shaft and the ninth connecting shaft are on the same side of the steering wheel, and the eighth connecting shaft and the tenth connecting shaft are on the other side of the steering wheel. For example, the seventh connecting shaft can be provided with a through hole along the axis 401, and the ninth connecting shaft can pass through the through hole and be arranged along the axis. Alternatively, the ninth connecting shaft can be provided with a through hole, and the seventh connecting shaft can be arranged through the through hole.

[0228] In some possible implementations, the steering wheel 10 can further include a first motor 330 and a first transmission assembly 340. The first transmission assembly 340 can be used to transmissionally connect the seventh connecting shaft to the first motor 330, so that the first motor 330 drives the seventh connecting shaft to rotate around the first axis 401.

[0229] For example, as shown in the steering wheel 10, Figure 4 For example, as shown in the steering wheel 10,

[0230] In an example, for the ninth connecting shaft, the steering wheel 10 can further be provided with another motor and a corresponding transmission assembly, so that the ninth connecting shaft can be driven to rotate by the motor, and in turn drive the lower hub portion to rotate.

[0231] On the one hand, due to the small space available in the steering wheel, it can be difficult to arrange corresponding multiple motors when the size of the steering wheel is small. On the other hand, using different motors to drive the seventh connecting shaft and the ninth connecting shaft will result in high cost. In some design ways, the steering wheel can use the same motor to drive the upper hub portion and the lower hub portion to rotate.

[0232] In some possible implementations, the steering wheel 10 can further include a second transmission assembly 350. The second transmission assembly 350 can be used to transmissionally connect the ninth connecting shaft to the first motor 330, so that the first motor 330 drives the ninth connecting shaft to rotate around the second axis 501.

[0233] In this embodiment, the same motor drives the seventh and ninth connecting shafts to rotate through different transmission components, which saves space within the steering wheel and reduces costs. Furthermore, since the seventh connecting shaft is connected to the upper wheel hub and the ninth connecting shaft is connected to the lower wheel hub, when the steering wheel switches between driving and stowage modes, it facilitates synchronous rotation of the upper and lower wheel hubs, reducing control complexity and shortening the time required for mode switching.

[0234] In some possible implementations, the reduction ratio of the first transmission assembly 340 may be less than the reduction ratio of the second transmission assembly 350.

[0235] For example, assuming the lower wheel hub requires a rotation angle of 45 degrees along axis 501 when the steering wheel mode is switched, and the upper wheel hub requires a rotation angle of 225 degrees along axis 401; if the reduction ratio of transmission assembly 350 can be 5 times that of transmission assembly 340, the time required for the upper wheel hub to rotate during steering wheel mode switching will be the same as the time required for the lower wheel hub to rotate. If the upper and lower wheel hubs start rotating at the same time, they can complete the mode switching simultaneously.

[0236] Since the upper and lower wheel hubs are retracted to the lower rear of the central section in the retracted mode, the upper wheel hub requires a greater rotation angle than the lower wheel hub when the steering wheel is switched. In this embodiment, by reasonably setting the transmission ratio of the first transmission component and the second transmission component, it is beneficial for the upper and lower wheel hubs to change their posture within the same time period when the steering wheel is switched, thus saving the total time required for mode switching.

[0237] For example, the first transmission assembly 340 and the second transmission assembly 350 can be driven by gear transmission, belt transmission, or a combination of transmission. The following uses belt transmission as an example. Figure 18 The first transmission assembly and the second transmission assembly are described exemplarily.

[0238] For example, Figure 18 This is a schematic diagram of a motor arrangement provided in an embodiment of this application.

[0239] Figure 18 The scheme shown can be understood as, in Figure 16 Based on the shown scheme, a motor 330, transmission components 340 and 350 are added. To better illustrate the components of transmission components 340 and 350, Figure 18 Adopted with Figure 16 Different perspectives.

[0240] Reference Figure 18The motor 330 can be mounted to the middle support 320. For example, an output shaft of the motor 330 can be connected with two pulleys (denoted as pulley #1 and pulley #2) of different diameters. When the motor 330 rotates, the two pulleys can be driven to rotate.

[0241] For the pulley #1, the pulley #1 can be drivingly connected with a pulley 341 through a belt 342. The pulley 341 can be disposed on the connecting shaft 410 and coaxially arranged with the connecting shaft 410. In this case, the transmission assembly 340 can include the pulley #1, the pulley 341 and the belt 342. For the sake of perspective, the pulley #1 is not shown in Figure 18 .

[0242] In an example, the pulley 341 can be connected with the connecting shaft 410 in a manner of welding, key connection, bolt connection, etc.

[0243] In another example, the pulley 341 and the connecting shaft 410 can be integrally formed.

[0244] In another example, the belts 342 and 352 can be toothed belts.

[0245] Similarly, for the pulley #2, the pulley #2 can be drivingly connected with a pulley 351 through a belt 352. The pulley 351 can be coaxially arranged with a connecting shaft 510 along an axis of the connecting shaft 510. In this case, the transmission assembly 350 can include the pulley #2, the pulley 351 and the belt 352. For the sake of perspective, the pulley #2 is not shown in Figure 18 .

[0246] Therefore, when the motor 330 rotates, the upper wheel hub 100 can be driven to rotate around the axis 401 through a transmission path of the pulley #1-belt 342-pulley 341-connecting shaft 410, and the lower wheel hub 100 can be driven to rotate around the axis 501 through a transmission path of the pulley #2-belt 352-pulley 351-connecting shaft 510.

[0247] In some possible implementation manners, the first motor can have a self-locking function. For example, taking the structure shown in Figure 18 as an example, in the scenario of mode switching of the steering wheel, when the upper and lower wheel hubs are rotated to the postures corresponding to target modes, the motor 330 can be controlled to be self-locked. After the motor 330 is self-locked, the upper and lower wheel hubs can be locked at the postures currently located through the transmission path between the motor and the upper and lower wheel hubs.

[0248] In the embodiments of the present application, by adopting the first motor with the self-locking function, the upper and lower wheel hubs can be locked at the corresponding postures without the need of setting a mechanical locking mechanism, which is beneficial to saving the arrangement space in the steering wheel.

[0249] In real-world scenarios, on the one hand, the self-locking function of the motor may experience occasional failures; on the other hand, in certain manual driving scenarios, users may apply significant force to the upper / lower wheel hubs when holding the steering wheel. If the motor's self-locking performance is poor, it may cause the upper / lower wheel hubs to rotate around the corresponding axes 401 and 501. This failure will seriously threaten driving safety.

[0250] For example, the steering wheel may include one or more locking pins, and the upper and lower hub portions may be provided with corresponding locking holes.

[0251] The following combination Figure 19 This is an example illustration.

[0252] In one example, refer to Figure 19 In (a), the steering wheel may include locking pins 361 and 362, which are movable relative to the central support 320 in the direction of the arrow. The upper wheel hub 100 may be provided with a locking hole 111 that matches the locking pin 361; the lower wheel hub 200 may be provided with a locking hole 211 that matches the locking pin 362. In driving mode, the locking pins 361 and 362 can be inserted into the corresponding locking holes to lock the upper and lower wheel hubs.

[0253] In another example, refer to Figure 19 In (b), the steering wheel may include a locking pin 363. (This is in contrast to...) Figure 19 Unlike (a), the locking pin 363 can engage with the locking hole 112 in the upper hub portion 100 and also with the locking hole 212 in the lower hub portion 200. The locking holes 112 and 212 can have different axes.

[0254] In another example, refer to Figure 19 In (c), the steering wheel may include a locking pin 364. (and) Figure 19 Unlike (b), the two locking holes 112 and 212 that cooperate with the locking pin 363 can be arranged along the same axis; moreover, the locking hole 212 can be a through hole.

[0255] Compared to Figure 19 In (a), Figure 19 In (b) and (c), the locking pin 363 can be matched with the locking holes of the upper and lower wheel hubs, and the upper and lower wheel hubs can be locked simultaneously with just one locking pin; compared with the method of using multiple locking pins to lock the upper and lower wheel hubs separately, the number of parts in the steering wheel used to drive the movement of the locking pin can be reduced, which is beneficial to saving the layout space in the steering wheel.

[0256] Compared to Figure 19 In (b) and (c), Figure 19In (a), the upper and lower wheel hubs are locked to the central support member by two locking pins, making it easier to adapt to different steering wheel designs. For example, in Figure 19 In (b) and (c), it may be necessary for the upper and lower hubs to have overlapping areas in the circumferential direction of the annular structure they form, while this requirement will not be involved in the scheme that uses two locking pins to lock the upper and lower hubs respectively.

[0257] In some possible implementations, the steering wheel may include a first locking pin, the upper hub portion 100 may include a first locking hole that engages with the first locking pin, and the lower hub portion 200 may include a second locking hole that engages with the first locking pin. For example, see reference... Figure 19 In (b) and (c), the locking pin 363 can correspond to the first locking pin, the locking hole 112 can correspond to the first locking hole, and the locking hole 212 can correspond to the second locking hole.

[0258] In this embodiment of the application, since both the first locking hole and the second locking hole can cooperate with the first locking pin, the upper and lower wheel hubs can be locked simultaneously through the locking pin.

[0259] In some possible implementations, the first keyhole and the second keyhole can be coaxially arranged. For example, refer to... Figure 19 In (c), keyholes 112 and 212 can be coaxially arranged; compared to Figure 19 The scheme shown in (b) can further save the space occupied by the locking pin and also avoid the failure mode where the locking pin can only cooperate with one of the key holes due to rotation.

[0260] In some possible implementations, the steering wheel 10 may also include a second motor 370 and a third transmission assembly 380, the third transmission assembly 380 being used to drive the first locking pin to the second motor so that the second motor 370 drives the first locking pin to move relative to the first lock hole and the second lock hole.

[0261] In this embodiment, a motor-driven locking pin is used, which can save users from manually locking and unlocking the upper and lower wheel hubs. It also facilitates linkage with other actuators in the cockpit, thereby providing users with a richer experience.

[0262] In some possible implementations, the third transmission assembly 380 may include a first transmission rod 381, a first locking pin seat 382 for setting the first locking pin, and a fourth transmission assembly 383. The first transmission rod 381 is drivenly connected to the first locking pin seat, and the fourth transmission assembly 383 may be used to drively connect the first transmission rod to the second motor 370.

[0263] The following is Figure 16 Taking the steering wheel shown as an example, let's assume it uses... Figure 19 The locking scheme shown in (c) is combined withFigure 20 The third and fourth transmission components are described exemplarily.

[0264] For example, Figure 20 This is a schematic diagram of a locking pin driving method provided in an embodiment of this application.

[0265] Figure 20 The scheme shown can be understood as, in Figure 16 Based on the illustrated scheme, a motor 370 and a transmission assembly 380 are added. To facilitate the presentation of the components of the transmission assembly 380, Figure 20 Adopted with Figure 16 Different perspectives.

[0266] Reference Figure 18 The transmission component 3831 can be located at the output end of the motor 370, and the transmission component 3832 can be located at one end of the transmission rod 381. The transmission components 3831 and 3832 can employ a worm gear transmission method. The transmission components 3831 and 3832 can constitute a fourth transmission assembly 383. The locking pin seat 382 can have a through hole through which the transmission rod 381 can pass and be threaded into the locking pin seat 382. The locking pin 363 can be located in the locking pin seat.

[0267] In this example, the rotation of motor 370 will drive transmission component 3831 to rotate, which in turn drives transmission rod 381 to rotate via transmission component 3832. When transmission rod 381 rotates, locking pin seat 382, ​​which is threadedly driven to transmission rod 381, will move in the left-right direction, thereby driving locking pin 363 to lock / unlock the upper and lower wheel hubs. Moreover, in this example, in the transmission path from motor 370 to locking pin 363, only locking pin seat 382 can move in the left-right direction of the steering wheel.

[0268] In one example, transmission component 3831 can be replaced with a gear, and correspondingly, transmission component 3832 can be replaced with a rack; locking pin seat 382 can be fixedly mounted on transmission rod 381. In this example, when motor 370 rotates, it can also drive locking pin 363 to lock / unlock the upper and lower wheel hubs through the transmission path of transmission component 383-transmission rod 381-locking pin seat 382. In this example, on the transmission path from motor 370 to locking pin 363, both transmission rod 381 and locking pin seat 382 can move in the left and right directions of the steering wheel; and Figure 20 Compared to the method shown, the total length of the components in the transmission assembly 380 that move along the locking direction of the locking pin will increase, and correspondingly, more arrangement space will be required.

[0269] In some possible implementations, the first transmission rod 381 and the first locking pin seat 382 can be connected by a threaded transmission.

[0270] For example, refer toFigure 20 The transmission rod 381 and the motor 370 are connected by a worm gear transmission; the transmission rod 381 and the locking pin seat 382 can be connected by a threaded transmission. Correspondingly, the intermediate support 320 can be provided with a limiting structure, so that the transmission rod 381 can rotate around its own axis but cannot move along its own axis.

[0271] In the embodiment of the application, the first transmission rod and the first locking pin seat are connected by a threaded transmission, which can reduce the total length of the parts that can move along the locking direction of the locking pin in the third transmission assembly, thereby saving the layout space in the steering wheel.

[0272] For example, when the steering wheel is in the driving mode, the first locking pin can be inserted into the first lock hole and the second lock hole; when the steering wheel is in the storage mode, the first locking pin can be outside the first lock hole and the second lock hole.

[0273] In the embodiment of the application, in the driving mode, the first locking pin is inserted into the first lock hole and the second lock hole, which is conducive to ensuring the normal use of the steering wheel by the user.

[0274] In some possible implementation manners, the steering wheel 10 can further include a second locking pin and a fifth transmission assembly, the first locking pin and the second locking pin can be arranged on opposite sides of the steering wheel; the upper hub 100 can further include a third lock hole matched with the second locking pin, and the lower hub 200 can include a fourth lock hole matched with the second locking pin; the fifth transmission assembly can drive connect the second locking pin to the second motor.

[0275] In some possible implementation manners, the first motor and the second motor can be arranged on the two sides of the intermediate support.

[0276] The above is only an exemplary description. Figure 21 The above is only an exemplary description.

[0277] With reference to Figure 21 The motor 330 can be arranged on the left side of the steering wheel and can drive the connecting shafts 410 and 510 to rotate through the transmission assemblies 340 and 350 respectively. The motor 370 can be arranged on the right side of the steering wheel, can drive the locking pin 363 to move through the transmission assembly 380, and can drive the locking pin 364 to move through the transmission assembly 390. The transmission assembly 390 can correspond to the fifth transmission assembly, and the locking pin 364 can correspond to the second locking pin.

[0278] In the embodiment of the application, the first motor and the second motor are arranged on opposite sides of the steering wheel respectively, which is conducive to the weight balance of the left and right sides of the steering wheel. Only a lighter counterweight or even no additional counterweight needs to be arranged, so that the steering wheel can be kept in the neutral position, thereby avoiding the unintended turning / yawing of the vehicle.

[0279] The above is only an exemplary description. Figures 2 to 21The application provides a steering wheel. The application also provides a steering control system.

[0280] The steering control system 600 can include any of the steering wheels. Figures 2 to 21 The steering control system 600 can also include a steering column, which can be connected with the steering wheel; for example, the steering column is connected with the steering wheel 10 through the central part 300 of the steering wheel.

[0281] In some possible implementations, the steering column can have a telescopic function.

[0282] The steering column can include a multi-stage pipe column arranged along an axis (for example, the third axis), and adjacent two stages of the multi-stage pipe column can be relatively moved along the third axis. Accordingly, the steering column can have different lengths when the multi-stage pipe column is in different postures. For example, by retracting the steering column, the overall retraction effect as shown in Figure 3 or Figure 10 can be achieved.

[0283] The application also provides a cockpit, which can include the steering wheel 10 and any of the possible implementations thereof.

[0284] The application also provides a vehicle, which can include any of the steering wheels, or can include the steering control system 600. Figures 2 to 21

For example, the vehicle in the application can be a hybrid electric vehicle (HEV), a range extended electric vehicle (REEV), a plug-in hybrid electric vehicle (PHEV) or a new energy vehicle (NEV), etc.
