When the vehicle 100 is in the first driving state, the steering wheel 2 is in the unfolded state, and the first driving state is a state where the vehicle 100 is in a driving state and the vehicle 100 has not enabled assisted driving.

[0134] In this way, when the steering wheel 2 is not needed, the steering wheel 2 can be folded up to reduce the space volume occupied by the steering wheel 2, so as to provide a larger activity space for the driver and improve the comfort of the driver in the cab. For example, when driving autonomously, the steering wheel 2 can also be folded, or when the vehicle 100 is in a non-driving state and enjoying entertainment functions in the vehicle, the steering wheel 2 can also be folded; when getting out of the vehicle, the steering wheel 2 can be automatically folded to facilitate the user to get out of the vehicle and improve the user experience.

[0135] In some cases, when it is necessary to use the steering wheel 2, the steering wheel 2 can be in the deployed state, so that it is convenient for the driver to hold the steering wheel 2 after sitting on the driver's seat, thus facilitating the driver to drive the vehicle 100. When the vehicle 100 is in a driving state, the steering wheel 2 can be deployed for safety considerations. For another example, when the driver gets into the vehicle, the steering wheel 2 can be automatically deployed, which has a welcome effect on the one hand and is also convenient for the user to drive the vehicle 100 without enabling assisted driving.

[0136] In some embodiments, the folding action may be: the steering wheel 2 rotates around the first direction, and the first direction is the width direction of the vehicle 100. That is, by rotating the steering wheel 2 around the first direction, the steering wheel 2 can be switched between the folded state and the deployed state, so that the state switching of the steering wheel 2 can be facilitated.

[0137] The steering wheel 2 in the present application can be automatically folded and deployed, can also be folded or deployed based on manual movement operations, and can also be folded or deployed based on user instructions.

[0138] The folding action can be driven by an automated structure, such as a motor drive. The folding action can also be achieved by the user manually operating a mechanical structure.

[0139] In some embodiments, the folding action may also be: the steering wheel 2 contracts relative to the instrument panel 8 of the vehicle 100. That is, the steering wheel 2 contracts from both sides to the middle to reduce the space occupied by the steering wheel 2, thereby providing the driver with a larger activity space.

[0140] In some embodiments, the folding action may also be: the first part 221 and the second part 222 of the handwheel 22 of the steering wheel 2 are folded with each other. That is, one of the first part 221 and the second part 222 of the steering wheel 2 is folded onto the other, so that the space used by the steering wheel 2 can also be reduced, thereby providing the driver with a larger activity space.

[0141] In some embodiments, the folding action may also be a combination of two or three of the above folding actions, and specific details are not elaborated herein.

[0142] In some other embodiments, the folding action may further include: the steering wheel 2 moves upward in the vertical direction; and / or, the steering wheel 2 moves downward in the vertical direction. In this way, by the steering wheel 2 moving vertically upward and / or vertically downward, the space required for the driver's activities can also be released, providing the driver with a larger activity space.

[0143] The folding action may include a combination of several of the above folding actions. The following lists the folding actions in several possible embodiments. The folding action of the present application is not limited to the following situations.

[0144] In some possible embodiments, the folding action includes the steering wheel 2 rotating downward about the first axis to be at least partially located below the instrument panel 8, or the steering wheel 2 rotating upward about the first axis to be at least partially located above the instrument panel 8.

[0145] In some possible embodiments, the folding action includes the steering wheel 2 rotating downward about the first axis, and the steering wheel 2 moving downward in the vertical direction so that the steering wheel 2 is at least partially retracted below the instrument panel 8.

[0146] In some possible embodiments, the folding action may further include, after the steering wheel 2 is retracted below the instrument panel 8, moving the steering wheel 2 upward so that the steering wheel 2 is close to the lower surface of the instrument panel, saving more interior space of the vehicle.

[0147] In some possible embodiments, the folding action may include that after the first part 221 and the second part 222 of the handwheel 22 of the steering wheel 2 are folded with each other, the steering wheel 2 is retracted relative to the instrument panel 8 into the instrument panel 8.

[0148] In some embodiments, in the folded state, the steering wheel 2 is at least partially located above the instrument panel 8 of the vehicle 100, or the steering wheel 2 is at least partially located below the instrument panel 8, or the steering wheel 2 is at least partially located inside the instrument panel 8. In this way, the space near the instrument panel 8 or the interior space of the instrument panel 8 can be reasonably utilized to accommodate the steering wheel 2, so as to improve the space utilization rate.

[0149] In some embodiments, the handwheel 22 of the steering wheel 2 includes a first part 221 and a second part 222 that can be folded with each other. In the folded state, the first part 221 and the second part 222 are folded. By folding the first part 221 and the second part 222, the space occupied by the steering wheel 2 can be reduced, so as to provide a larger activity space for the driver.

[0150] In some examples, the handwheel 22 can be a closed ring or a semi-closed ring.

[0151] Optionally, the first part 221 and the second part 222 can be semicircular, rectangular, etc.

[0152] In some embodiments, the first part 221 of the handwheel 22 is located on the left side of the second part 222. That is to say, the first part 221 and the second part 222 of the handwheel 22 are arranged along the width direction of the vehicle 100, so that it is convenient for the driver to hold the handwheel 22, and thus it is convenient to control the steering wheel 2.

[0153] In some embodiments, the folding action includes the first part 221 and the second part 222 of the handwheel 22 of the steering wheel 2 folding with respect to each other, and the steering wheel 2 contracting relative to the instrument panel 8 of the vehicle 100. In this way, the space occupied by the steering wheel 2 can be reduced by the mutual folding of the first part 221 and the second part 222, and then the folded first part 221 and second part 222 can be contracted along the instrument panel 8, for example, to below the instrument panel 8 or inside the instrument panel 8, so as to further release the space in the cab and facilitate the storage of the steering wheel 2.

[0154] In some embodiments, the folding action further includes: the steering wheel 2 rotating to a position where the first part 221 and / or the second part 222 are parallel to the instrument panel 8 of the vehicle 100. In this way, the space behind the instrument sleeve where the steering wheel 2 is located can also be made smaller, thus providing a larger activity space for the driver and improving the comfort of the driver in the cab.

[0155] In some embodiments, the steering wheel 2 is further configured to be able to rotate about the rotation axis 4b of the steering wheel 2 to control the driving direction of the vehicle 100. Among them, the direction of the rotation axis 4b of the steering wheel 2 can be perpendicular to the first direction. In this way, the driver can rotate the steering wheel 2 about the rotation axis 4b of the steering wheel 2 to adjust the steering of the wheels, thereby controlling the driving direction of the vehicle 100.

[0156] In some alternative embodiments, when the steering wheel 2 is in the folded state, the steering wheel 2 can also rotate about the rotation axis 4b, so as to facilitate the driver to operate the steering wheel 2 to control the driving direction of the vehicle 100 when the steering wheel 2 is folded.

[0157] In some embodiments, when the steering wheel 2 is in the folded state, the steering wheel 2 can rotate about the rotation axis 4b of the steering wheel 2 to receive the operation instructions of the driver. In this way, not only can the driver have a larger activity space, but also it is convenient for the driver to output operation instructions to the steering wheel 2 to control the driving direction of the vehicle 100, further improving the driving experience effect of the driver.

[0158] In some embodiments, please refer to Figure 2 , the steering device 200 further includes a connection component 1, and the steering wheel 2 is connected to the vehicle body 20 of the vehicle 100 through the connection component 1. Through the connection component 1, the square steering wheel can be connected to the vehicle body 20, so as to facilitate the support of the steering wheel 2, and further facilitate the driver to control the steering wheel 2.

[0159] In some embodiments, the connection assembly 1 includes a rotating member 4a and a connecting member 43. The steering wheel 2 is rotatably connected to the rotating member 4a. The steering wheel 2 can rotate relative to the rotating member 4a about a first direction, and the first direction is the width direction of the vehicle 100. The connecting member 43 connects the rotating member 4a and the body 20 of the vehicle 100.

[0160] Optionally, the connecting member 43 may include a column.

[0161] Through the cooperation of the rotating member 4a and the connecting member 43, the connection between the steering wheel 2 and the body 20 can be realized, and it is convenient for the steering wheel 2 to rotate relative to the rotating member 4a about the first direction, so as to facilitate the switching of the steering wheel 2 between the folded state and the unfolded state.

[0162] In some embodiments, the steering wheel 2 can rotate relative to the rotating member 4a about a second direction to receive the steering command of the driver, and the second direction is the central axis of the steering wheel 2. Among them, the central axis is the rotation axis 4b line of the steering wheel 2 itself. In this way, through the cooperation of the rotating member 4a and the connecting member 43, the driving direction of the vehicle 100 can also be controlled by the steering wheel 2, so as to facilitate the driver to control the steering wheel 2.

[0163] In some embodiments, the connecting member 43 can drive the steering wheel 2 to move along the length direction of the connecting member 43. In this way, the folding action of the steering wheel 2 can be realized by driving the steering wheel 2 to move along the length direction of the connecting member 43, so as to facilitate the state adjustment of the steering wheel 2.

[0164] In some embodiments, the connecting member 43 can drive the steering wheel 2 to move in the up and down direction. In this way, the folding action of the steering wheel 2 can be realized by driving the steering wheel 2 to move in the up and down direction, so as to facilitate the state adjustment of the steering wheel 2.

[0165] In some embodiments, the connecting member 43 can be a rod-shaped structure, a tubular structure, a plate-shaped structure or other irregular structures, etc. The rotating member 4a can be a rod-shaped structure, a plate-shaped structure, a Y-shaped structure, a U-shaped structure, etc. The present application does not make specific limitations on this.

[0166] In some other embodiments, the connection assembly 1 can also be a rod-shaped structure, a plate-shaped structure, etc.

[0167] In some embodiments, the steering device 200 further includes a driving device, and the driving device is used to drive the steering wheel 2 to perform the folding action. In this way, the state of the steering wheel 2 can be quickly adjusted through the driving device, so as to facilitate the adjustment of the state of the steering wheel 2.

[0168] In some examples, the driving device can be an electric driving device such as a rotary motor, or a manual driving device such as a crank. In this application, the driving device is an rotary motor for exemplary illustration.

[0169] In some embodiments, the steering device 200 further includes a support base 21, and the support base 21 is connected to the connection assembly 1. The support base 21 is used to support the handwheel 22 of the steering wheel 2.

[0170] In some embodiments, the handwheel 22 is provided with an avoidance notch. When in the folded state, the connection assembly 1 is located within the avoidance notch. In this way, when the steering wheel 2 is in the folded state, it can be closer to the instrument panel 8, thereby releasing more space to further improve the comfort of the driver.

[0171] In some embodiments, the steering device 200 further includes an airbag, and the airbag is installed on the support base 21. In the folded state, the airbag is located between the instrument panel of the vehicle 100 and the driver's seat of the vehicle 100. In this way, when the steering wheel 2 is in the folded state, the airbag can also be ejected smoothly to ensure the safety of the driver.

[0172] In some embodiments, in the folded state, the support base 21 is located between the instrument panel of the vehicle 100 and the driver's seat of the vehicle 100. The support base 21 is arranged between the instrument panel of the vehicle 100 and the driver's seat, which can ensure that the airbag provided therein is in a more appropriate position, thereby ensuring that the airbag can effectively protect the driver.

[0173] In some embodiments, when performing the folding action, the position of the support base 21 remains unchanged. In this way, the stability of the position of the support base 21 can be ensured, thereby ensuring the stability of the position of the airbag and improving the effectiveness of the airbag during operation.

[0174] In some embodiments, please refer to Figures 2 - 7 , the steering wheel 2 can rotate relative to the support base 21 about a first direction. In this way, it is convenient to set the steering wheel 2 to rotate about the first direction, thereby facilitating the adjustment of the state of the steering wheel 2.

[0175] In some embodiments, the driving device of the steering device 200 includes a first driving member 41a, and the first driving member 41a is used to drive the steering wheel 2 to rotate about the first direction. The driving device is fixed on the support base 21 or the connection assembly 1 of the steering device 200. By driving the steering wheel 2 to rotate through the first driving member 41a, the state of the steering wheel 2 can be conveniently adjusted, and the adjustment efficiency can be improved.

[0176] In some examples, the first driving member 41a may be a rotating motor or other device capable of driving the steering wheel 2 to rotate.

[0177] In some embodiments, the steering device 200 includes a first rotating shaft 41b, the first rotating shaft 41b is rotatably connected to the support base 21, and is connected to the steering wheel 2 so that the steering wheel 2 can rotate around the first direction. Wherein, the axial direction of the first rotating shaft 41b is consistent with the first direction.

[0178] In this way, the rotation of the first rotating shaft 41b relative to the support base 21 can drive the steering wheel 2 to rotate around the axis of the first rotating shaft 41b, so that the steering wheel 2 can be switched between the folded state and the unfolded state. This structure is relatively simple and convenient for adjusting the state of the steering wheel 2.

[0179] In some embodiments, the steering device 200 further includes a first transmission assembly 42a, and the first transmission assembly 42a is connected between the first rotating shaft 41b and the first driving member 41a. By providing the first transmission member, it is convenient to connect the first driving member 41a and the first rotating shaft 41b, so as to facilitate the first driving member 41a to drive the first rotating shaft 41b to rotate, and further facilitate driving the steering wheel 2 to rotate to adjust the state of the steering wheel 2.

[0180] In some embodiments, the first transmission assembly 42a includes a first worm gear 42a1 and a first worm 42a2, and the first turbine is connected to the first rotating shaft 41b; the first worm 42a2 meshes with the first worm gear 42a1 and is in transmission connection with the first driving member 41a. The transmission mode of the worm and worm gear can make the power of the first driving member 41a more stable during the process of being transmitted to the first rotating shaft 41b, so as to facilitate the stable rotation of the first rotating shaft 41b.

[0181] In some embodiments, the first transmission assembly 42a further includes a second worm gear 42a3 and a second worm 42a4, and the second turbine is connected to the first worm 42a2; the second worm 42a4 meshes with the second worm gear 42a3 and is connected to the first driving member 41a. The cooperation of the second worm gear 42a3 and the second worm 42a4 can further improve the stability of the power transmission of the first driving member 41a, so that the rotation of the first rotating shaft 41b is more stable.

[0182] Moreover, the cooperation of the second worm gear 42a3 and the second worm 42a4, combined with the cooperation of the first worm gear 42a1 and the first worm 42a2, can make the position configuration of the first driving member 41a and the first rotating shaft 41b more flexible and reasonable, so as to save space.

[0183] In some other embodiments, the first transmission assembly 42a can also be other structures capable of transmitting the power of the first driving member 41a to the first rotating shaft 41b, such as a gear 621 structure, a belt drive structure, a chain drive structure, and the like.

[0184] In some embodiments, the steering device 200 further includes a base 1a, the base 1a is connected to the support seat 21, and is slidably connected to the connecting assembly 1 along the direction of the second axis. Wherein, the direction of the second axis can be consistent with the length direction of the connecting assembly 1. In this way, by slidably connecting the base 1a to the connecting assembly 1 along the direction of the second axis, the base 1a can slide on the connecting assembly 1, which can drive the steering wheel 2 to move along the second axis direction to adjust the height of the steering wheel 2, so as to release more space for the steering wheel 2. For example, when the steering wheel 2 switches to the folded state, the steering wheel 2 can be rotated along the first direction to the lower part of the instrument panel 8, and then moved downward along the second axis direction, so that the steering wheel 2 can move more to the lower part of the instrument panel 8, thereby releasing more space.

[0185] In some embodiments, the steering device 200 further includes a first telescopic assembly 5a, the first telescopic assembly 5a is connected to the connecting assembly 1 and is connected to the base 1a, and is used to drive the base 1a to slide on the connecting assembly 1. In this way, the first telescopic assembly 5a can more conveniently drive the base 1a to slide on the connecting assembly 1, so as to conveniently adjust the position of the steering wheel 2.

[0186] In some embodiments, the first telescopic assembly 5a includes a second driving member 5a1 and a second transmission assembly 5a2, and the second transmission assembly 5a2 is connected between the second driving member 5a1 and the connecting assembly 1. Through the cooperation of the second driving member 5a1 and the second transmission assembly 5a2, the base 1a can be more stably driven to slide on the connecting assembly 1, so that the adjustment of the steering wheel 2 is more stable.

[0187] In some examples, the second driving member 5a1 can be a rotating motor, an electric push rod or other structures capable of driving the base 1a to slide.

[0188] In some embodiments, the second transmission assembly 5a2 includes a third worm 5a21 and a third worm gear 5a22, the third worm 5a21 is connected to the second driving member 5a1; the third worm gear 5a22 meshes with the third worm 5a21 and is rotatably connected to the connecting assembly 1. Through the transmission mode of the worm and worm gear, the power of the second driving member 5a1 can be transmitted to the base 1a more stably, so as to facilitate the stable driving of the base 1a to slide.

[0189] In some other embodiments, the second transmission assembly 5a2 may also be a chain drive structure, a belt drive structure, a gear 621 drive structure, and so on.

[0190] In some embodiments, the steering device further includes a movable mechanism 4. The connecting device of the steering wheel 2 and the steering device is rotatably connected through the movable mechanism 4, and the connecting device is directly or indirectly connected to the vehicle body.

[0191] The steering wheel 2 can rotate around a first direction through the movable mechanism 4. The first direction is the width direction of the vehicle, so that a rotation action around the first direction can be performed. Alternatively, the steering wheel 2 can rotate around the first direction and the rotation direction of the steering wheel through the movable mechanism 4. The rotation direction of the steering wheel is the rotation center line when the steering wheel receives a user's steering operation. In this way, in an emergency, the driver can urgently hold the steering wheel 2 to perform an emergency direction operation, improving safety.

[0192] Optionally, in an embodiment of the present disclosure, the movable mechanism includes a first movable body 44 and a first rotating shaft 41 arranged along the first rotation axis direction. The first movable body 44 is connected to the steering wheel 2, and the first rotating shaft 41 is directly or indirectly connected to the connecting device. The first movable body 44 rotates around the first rotation axis through the first rotating shaft 41 to drive the steering wheel to rotate around the first rotation axis.

[0193] Wherein, when the first rotating shaft 41 rotates, it drives the first movable body 44 and the steering wheel 2 to rotate around the first direction together, realizing rotational folding.

[0194] Optionally, the first movable body 44 may include a steering wheel electric drive body, which can realize signal acquisition, thereby realizing steer-by-wire.

[0195] Optionally, in an embodiment of the present disclosure, the movable mechanism further includes a driving member 42. The first rotating shaft 41 is connected to the connecting device through the driving member 42. The driving member 42 drives the first rotating shaft 41 to rotate.

[0196] Of course, in some other examples, the driving member 42 may not be provided, and the steering wheel 2 can be rotated and folded by manually operating the steering wheel 2 to rotate around the first rotation axis.

[0197] In some embodiments, please refer to Figures 8 - 16 , when the steering device is in the unfolded state, the steering wheel 2 is located behind the instrument panel 8. When the steering device is in the folded state, at least a part of the steering wheel 2 is located below the instrument panel 8.

[0198] Among them, in the unfolded state, the driver can normally drive the vehicle through the steering wheel 2. At this time, the steering wheel 2 is behind the instrument panel 8, and the driver sitting in the driver's cab can hold the steering wheel 2 to perform steering operations. In the folded state, the steering wheel 2 can be folded without the need to use the steering wheel 2. This can reduce the space occupied by the steering wheel 2 in the driver's seat, making the driver's activity space larger and the riding experience better. For example, but not limited to, in the parked state, or when the vehicle is in the intelligent driving or autonomous driving state, the steering wheel 2 can be folded.

[0199] In the above technical solution, the steering wheel 2 can be folded under the instrument panel, reducing the occupied space of the driver's seat and making the driver's activity space larger and more comfortable. By setting the steering wheel 2 under the instrument panel 8 when it is not needed for operation, there is no need to redesign the accommodation space on the instrument panel 8, and it can be directly applied to the instrument panel 8 of existing vehicle models, without increasing costs or causing an increase in the development cycle, ensuring efficiency. In addition, it can be applicable to the styling designs of the instrument panels 8 and steering wheels 2 of different vehicle models, without the need for special development, and can be quickly and widely applied to different vehicle models. When the steering wheel 2 is not needed for operation, the steering wheel 2 can be set under the instrument panel 8.

[0200] Optionally, in an emergency, the driver can urgently hold the steering wheel 2 to perform emergency steering operations, improving safety.

[0201] Optionally, in an embodiment of the present disclosure, the steering wheel 2 is set to be able to rotate around a first direction, and the first direction is consistent with the width direction of the vehicle. This facilitates at least partially retracting the steering wheel 2 under the instrument panel 8.

[0202] Among them, the steering wheel 2 adopts a rotatable manner and can at least partially retract under the instrument panel 8 to make room for the driver's cab. In the case where the vehicle is in the autonomous driving state or when the driver gets in and out of the vehicle, the space utilization rate of the driver's cab can be improved, thereby improving the comfort of the driver.

[0203] Among them, the fact that the first direction is consistent with the width direction of the vehicle can reflect that the steering wheel 2 rotates around the first direction for folding, enabling storage. And the steering wheel 2 itself rotates around a second axis to enable vehicle steering.

[0204] Optionally, in another embodiment of the present disclosure, the steering wheel 2 is set to translate in the front-back direction to at least partially retract the steering wheel 2 under the instrument panel 8. It can be understood that the steering wheel 2 does not fold but directly moves, and after moving, it can at least partially retract under the instrument panel 8, and can also make room for the driver's cab.

[0205] It can be understood that the unfolded state of the steering wheel 2 can be a state in which the driver can hold the steering wheel 2 to perform a steering operation, and the steering wheel 2 is generally arranged in the up-down direction. The folded state of the steering wheel 2 can be that the steering wheel 2 rotates and tilts in a certain direction to achieve rotational folding, so that the steering wheel 2 can be generally arranged in the horizontal direction.

[0206] Among them, in the unfolded state, the steering wheel 2 is in a situation where the steering wheel 2 needs to be operated during normal driving, and the driver sitting in the driver's cab can hold the steering wheel 2 to perform a steering operation. In the folded state, generally, the steering wheel 2 does not need to be operated by the driver. At this time, the steering wheel 2 is located below the instrument panel 8, which can reduce the space occupied in the driver's cab and also avoid excessive encroachment on the space of the driver's legs, ensuring the leg space of the driver.

[0207] Optionally, in an embodiment of the present disclosure, in the folded state, the entire steering wheel 2 is retracted below the instrument panel 8.

[0208] Among them, when it is said that the entire steering wheel 2 is retracted below the instrument panel 8, it can be that in the folded state, the projection of the steering wheel 2 in the vehicle height direction is set as the first projection area, and the projection of the instrument panel 8 in the vehicle height direction is set as the second projection area, and the first projection area entirely falls within the second projection area, so that the steering wheel 2 can be entirely retracted below the instrument panel 8. By setting it in this way, the entire steering wheel 2 can be retracted below the instrument panel 8, which can further improve the space utilization rate of the driver's cab and improve comfort. It can be understood that when the entire steering wheel 2 is retracted below the instrument panel 8, that is, looking down from above, the instrument panel 8 completely blocks the steering wheel 2. Of course, in some other examples, when the entire steering wheel 2 is retracted below the instrument panel 8, it can be that the entire steering wheel 2 is located below the instrument panel 8 in the height direction and is partially blocked by the instrument panel 8.

[0209] Optionally, in an embodiment of the present disclosure, the steering wheel 2 includes a support base 21 and a handwheel 22, and the handwheel 22 is connected to the support base 21. In the folded state, both the support base 21 and the handwheel 22 are located below the instrument panel 8. Among them, the handwheel 22 is used for the driver to hold, and the support base 21 provides a supporting effect on the handwheel 22. By retracting both the support base 21 and the handwheel 22 below the instrument panel 8, the space utilization rate of the driver's cab can be further improved.

[0210] Among them, in some examples, the support base 21 and the handwheel 22 can rotate together around a first direction to achieve overall folding movement. In some other examples, the support base 21 can also remain stationary, and the handwheel 22 can be rotated around the first direction to achieve folding movement.

[0211] Optionally, in another implementation of the present disclosure, in the folded state, the steering wheel 2 can be partially retracted under the instrument panel 8. That is to say, when viewed from top to bottom, a part of the steering wheel 2 can be blocked by the instrument panel 8, and the other part is not blocked by the instrument panel 8.

[0212] Among them, in the folded state, a part of the steering wheel 2 being retracted under the instrument panel 8 can be that a part of the support base 21 is located under the instrument panel 8, or a part of the handwheel 22 is located under the instrument panel 8. It can also be that the support base 21 is not retracted under the instrument panel 8, and the entire handwheel 22 of the steering wheel 2 is retracted under the instrument panel 8, which can be set according to needs.

[0213] Optionally, in an implementation of the present disclosure, the steering device further includes a shielding mechanism. The shielding mechanism includes a closure member 31 configured to form a receiving space with the lower surface of the instrument panel 8, and the receiving space is used to receive the steering wheel 2 in the folded state. By providing the closure member 31, the steering wheel 2 can be shielded, so that the instrument panel 8 maintains consistency and aesthetics. It can be understood that after the steering wheel 2 is retracted under the instrument panel 8, it can be placed in the receiving space, and at this time, the closure member 31 can shield the steering wheel 2.

[0214] Optionally, in an implementation of the present disclosure, the steering device further includes a connection assembly 1. The connection assembly 1 is connected to the vehicle body, and the steering wheel 2 is connected to the connection assembly 1. The steering wheel 2 is configured to be able to move along the length direction of the connection assembly 1 and / or be able to move in the up and down direction.

[0215] Among them, the connection assembly 1 is used to support the steering wheel 2, so that in the unfolded state, the steering wheel 2 is located behind the instrument panel 8, enabling the driver to hold the steering wheel and perform steering operations. In addition, the position of the steering wheel 2 can be adjusted by adjusting the position of the connection assembly 1 to adapt to drivers of different body types.

[0216] Among them, the steering wheel 2 can move along the length direction of the connection assembly 1, so that the steering wheel 2 can move back and forth, thereby changing the position of the steering wheel 2. In some examples, the steering wheel 2 can move while the connection assembly 1 remains different. In other examples, the steering wheel 2 and the connection assembly 1 can move together. It should be noted that the steering wheel 2 is set as a steer-by-wire steering wheel, and the steering wheel 2 uses electrical signals to achieve the steering of the wheels. The connection assembly 1 does not play a role in the transmission of wheel steering. The connection assembly 1 is used to support the steering wheel 2.

[0217] Among them, in the above implementation, the first direction of the steering wheel 2 is set at an angle to the axis of the connection assembly 1, so that the steering wheel 2 can rotate towards the side of the connection assembly 1 to achieve the rotational folding of the steering wheel 2.

[0218] Optionally, in an embodiment of the present disclosure, the steering device further includes a closure member 31. The steering wheel 2 is connected to the connection assembly 1. A through hole 81 is formed in the instrument panel 8 for the connection assembly 1 to pass through. The closure member 31 is movably disposed at the through hole 81. In the deployed state, the closure member 31 at least partially opens the through hole 81. In the folded state, the closure member 31 closes the through hole 81.

[0219] Among them, through the provided through hole 81, a part of the connection assembly 1 can be inside the instrument panel 8, and the other part is connected to the steering wheel 2 through the through hole 81, so that in the deployed state, the steering wheel 2 is behind the instrument panel 8. The movable setting of the closure member 31 enables that in the deployed state, that is, when the steering wheel 2 needs to be behind the instrument panel 8, the through hole 81 is at least partially opened, and at this time, the connection assembly 1 can pass through, so as to ensure that the steering wheel 2 is behind the instrument panel 8. In the folded state, when the steering wheel 2 is retracted below the instrument panel 8, at this time, the connection assembly 1 is not passing through the through hole 81, and the through hole 81 can be closed by the closure member 31 to prevent the structure inside the instrument panel 8 from being exposed through the through hole 81, affecting the aesthetics. In some examples, the through hole 81 penetrates the instrument panel 8 in the front-rear direction.

[0220] Among them, in some examples, the closure member 31 is movably connected to the instrument panel and disposed at the through hole 81, so as to close the through hole 81. In other examples, the closure member 31 can also be connected to other structures and disposed at the through hole 81 to close the through hole 81.

[0221] Optionally, in an embodiment of the present disclosure, the instrument panel 8 is provided with a connection through hole 82. The connection through hole 82 includes a first part 821 and a second part 822. The first part 821 is formed as the through hole 81. In the deployed state, the connection assembly 1 passes through the first part 821. In the folded state, the connection assembly 1 passes through the second part 822.

[0222] Among them, both the first part 821 and the second part 822 can be penetrated by the connecting component 1. According to the different positions of the connecting component 1, it can be penetrated in the first part 821 or the second part 822 respectively to meet different requirements. It can be understood that the first part 821 and the second part 822 are interconnected, and the connecting component 1 can be switched between the first part 821 and the second part 822. In the unfolded state, the connecting component 1 is penetrated in the first part 821, so that the steering wheel 2 is located behind the instrument panel 8. In the folded state, the connecting component 1 is penetrated in the second part 822, so that the steering wheel 2 is located below the instrument panel 8. Among them, in the folded state, after the connecting component 1 is penetrated in the second part 822, the first part 821 is in an exposed state, and at this time, it can be closed by the closing member 31. In some examples, the first part 821 is located above the second part 822, and the connecting component 1 can move up and down, so that the connecting component 1 is switched between the first part 821 and the second part 822.

[0223] Optionally, in an embodiment of the present disclosure, the second part 822 is located on the lower surface of the instrument panel 8, and the first part 821 is at least partially located on the side of the instrument panel 8 facing the driver's seat of the vehicle. By setting it like this, it is beneficial for the connecting component 1 to be penetrated in the second part 822 when the steering wheel 2 is located below the instrument panel 8, and for the connecting component 1 to be penetrated in the first part 821 when the steering wheel 2 is located behind the instrument panel 8.

[0224] Optionally, in an embodiment of the present disclosure, the steering device further includes a fifth driving member 32, and the driving end of the fifth driving member 32 is connected to the closing member 31 to drive the closing member 31 to move.

[0225] Among them, the fifth driving member 32 can drive the closing member 31 to move, so that the closing member 31 can be actively driven to close the through hole 81, without the need for manual operation, improving convenience. In addition, the fifth driving member 32 can be associated with the movement of the steering wheel 2, so that after the steering wheel 2 is retracted below the instrument panel 8, the fifth driving member 32 drives the closing member 31 to move to close the through hole 81. Of course, optionally, in some other embodiments, the closing member 31 can be moved manually so that the closing member 31 closes the through hole.

[0226] Optionally, in an embodiment of the present disclosure, the fifth driving member 32 is configured to be able to drive the closing member 31 to move in a direction close to or away from the through hole 81, and be able to avoid the connecting component 1 during the movement.

[0227] Among them, the closing member 31 can approach or move away from the through opening 81 under the drive of the fifth driving member 32. It can be understood that when it is necessary to close the through opening 81, the closing member 31 approaches the through opening 81 under the drive of the fifth driving member 32, and when it is necessary to at least partially open the through opening 81, the closing member 31 moves away from the through opening 81 under the drive of the fifth driving member 32. In some examples, the closing member 31 is designed as a separate part from the instrument panel 8, so that the closing member 31 can move relative to the instrument panel 8 to realize connection or separation from the instrument panel 8. When the closing member 31 is connected to the instrument panel 8, the through opening 81 is closed, and when separated from the instrument panel 8, the through opening 81 is at least partially opened.

[0228] Among them, during the movement of the closing member 31, it can avoid the connection component 1 to prevent interference between the connection component 1 and the closing member 31, which may affect the closing effect of the closing member 31 on the through opening 81.

[0229] Optionally, in another implementation manner of the present disclosure, the closing member 31 can be hinged to the instrument panel 8, and the fifth driving member 32 can drive the closing member 31 to rotate to realize closing of the through opening 81 or at least partially opening the through opening 81.

One end of the telescopic rod is hinged to the closing member 31, and the other end of the telescopic rod is used for hinging to the skeleton of the instrument panel 8. Through the telescopic action of the telescopic rod, the movement of the fifth driving member 32 can be driven, and the hinging of the telescopic rod to the closing member 31 can make the closing member 31 face the through opening 81 directly when approaching or moving away from the through opening 81, which can ensure the closing effect, avoid misalignment and other situations, and ensure the movement of the closing member 31. In some examples, the telescopic rod can be an electric push rod, and the electric push rod is driven by electric energy to extend or shorten.

[0232] Optionally, in one implementation manner of the present disclosure, the steering device further includes a guiding component 33. One end of the guiding component 33 is connected to the closing member 31, and the other end of the guiding component 33 is used for connecting to the skeleton of the instrument panel 8 so that the closing member 31 moves along the preset direction of the guiding component 33.

[0233] Among them, the guiding component 33 can guide the moving direction of the closing member 31, so that the closing member 31 moves in the preset direction of the guiding component 33, which can ensure the moving stability of the closing member 31, thereby ensuring alignment with the through-hole 81 and realizing the closing of the through-hole 81. Among them, the guiding component 33 is supported by the skeleton of the instrument panel 8 to ensure stability, so that stable guiding can be ensured during the movement of the closing member 31.

[0234] Optionally, in an embodiment of the present disclosure, the guiding component 33 includes a guide rail 331 and a connecting rod 332. The guide rail 331 is connected to the skeleton of the instrument panel 8. The guide rail 331 is provided with a track 333. One end of the connecting rod 332 is slidably hinged to the track 333, and the other end of the connecting rod 332 is hinged to the closing member 31.

[0235] Among them, the track 333 on the guide rail 331 realizes guiding, and the connecting rod 332 realizes the connection with the closing member 31, so that the closing member 31 moves along the extending direction of the track 333 on the guide rail 331 to realize the guiding function. One end of the connecting rod 332 can move along the extending direction of the track 333, and the connecting rod 332 generates a linkage effect, thereby driving the movement of the closing member 31. Among them, the hinge connection between the connecting rod 332 and the track 333, and the hinge connection between the connecting rod 332 and the closing member 31 can make the closing member 31 face the through-hole 81 directly during the movement, which is beneficial to the closing of the through-hole 81. It can be understood that when the closing member 31 moves along the extending direction of the track 333, the connecting rod 332 can rotate relative to the track 333 and the closing member 31, so that the closing member 31 faces the through-hole 81 directly. In some examples, a pulley is provided at one end of the connecting rod 332. The pulley is slidably connected to the track 333. One end of the connecting rod 332 is rotatably connected to the axis of the pulley, and the other end of the connecting rod 332 is hinged to the closing member 31 through a pin shaft.

[0236] Optionally, in an embodiment of the present disclosure, the connecting rod 332 includes a first connecting rod 3321 and a second connecting rod 3322. The first connecting rod 3321 and the second connecting rod 3322 are hinged to each other. The first connecting rod 3321 is slidably hinged to the track 333, and the end of the second connecting rod 3322 away from the first connecting rod 3321 is hinged to the closing member 31. By providing the first connecting rod 3321 and the second connecting rod 3322, the closing member 31 can move in multiple directions, which is beneficial to avoiding the connecting component 1 and preventing interference with the connecting component 1. It can be understood that the mutual connection between the first connecting rod 3321 and the second connecting rod 3322 enables the first connecting rod 3321 and the second connecting rod 3322 to rotate relative to each other. Therefore, when the moving direction of the closing member 31 changes, there will be no problem of restricted movement, which is beneficial to adjusting the position of the closing member 31.

[0237] Among them, the track 333 includes a first section and a second section. The first section and the second section are interconnected. The first section extends in the front-rear direction, and the second section extends in the left-right direction. Thus, the closure 31 can move in the front-rear direction and the left-right direction, which is beneficial for avoiding the connection assembly 1.

[0238] Optionally, in an embodiment of the present disclosure, two guide rails 331 are provided. The two ends of the first link 3321 are respectively slidably hinged to the tracks 333 of the two guide rails 331.

One ends of the two second links 3322 are respectively hinged to the first link 3321, and the other ends of the two second links 3322 are respectively hinged to the closure 31. The lengths of the two second links 3322 are set to be different. By providing the two second links 3322, two limiting effects are generated, which can limit the degrees of freedom of the closure 31, thereby facilitating the closure 31 to maintain a direct opposition to the through hole 81 and ensuring the closing effect of the closure 31 on the through hole 81.

[0240] Among them, the connection positions of the one ends of the two second links 3322 with the first link 3321 do not coincide, and the connection positions of the other ends of the two second links 3322 with the closure 31 do not coincide either. The connection positions of the other ends of the two second links 3322 with the closure 31 can be spaced in the left-right direction, thereby facilitating the closure 31 to maintain a direct opposition to the through hole 81 and improving the closing effect.

[0241] Among them, the first link 3321 can be inclined, which can adapt to the different lengths of the two second links 3322. Thus, the two second links 3322, the closure 31, and the first link 3321 form an irregular polygon structure, which can improve the movement stability of the two second links 3322, the closure 31, and the first link 3321.

It can be understood that the second rotating shaft 41 does not play the role of operating the steering wheel 2 to steer the wheels, but is for the steering wheel 2 to rotate and fold, and is used to be received under the instrument panel 8. And the rotation of the steering wheel 2 around the second axis can achieve the function of operating the steering wheel to steer the wheels.

[0248] Optionally, in the folded state, the steering wheel 2 can rotate around the second axis. That is to say, after the steering wheel 2 is folded under the instrument panel 8, it can also operate the steering wheel 2 to rotate around the second axis to achieve the function of operating the steering wheel to steer the wheels.

Thus, the connection relationship between the steering wheel 2 and the first movable body 44 remains unchanged, so that the steering wheel 2 can rotate around the second steering axis in the folded state. In some examples, the first movable body 44 may include two connecting arms connected to each other, and the two connecting arms are respectively connected to both ends of the second rotating shaft 41, and the steering wheel 2 is connected to the two connecting arms.

Wherein, the lifting driving member 61 generates a rotational force, and drives the connection assembly 1 to move in the up and down directions through the lifting transmission assembly 62, so that the steering wheel 2 can be driven to move up and down.

[0280] Optionally, in one embodiment of the present disclosure, the lifting transmission assembly 62 includes a gear 621 and a rack 622. The gear 621 is connected to the output end of the lifting driving member 61, the rack 622 meshes with the gear 621, and the rack 622 is connected to the connection assembly 1.

[0281] Among them, the lifting driving member 61 drives the gear 621 to rotate. The gear 621 meshes with the rack 622. When the gear 621 rotates, the rack 622 can move along the extending direction of the rack 622, converting the rotational force into a linear motion. The rack 622 is connected to the connecting component 1, thereby realizing the movement of the connecting component 1. The rack 622 extends in the vertical direction, thereby driving the connecting component 1 to move in the vertical direction, and further driving the steering wheel 2 to move in the vertical direction.

[0282] Optionally, in another embodiment of the present disclosure, the lifting assembly 6 includes an electric push rod. The electric push rod is arranged in the vertical direction and can extend or contract in the vertical direction. The connecting component 1 is connected to the electric push rod, so that the electric push rod drives the connecting component 1 to move up and down.

[0283] Optionally, in an embodiment of the present disclosure, the steering device further includes a guiding structure 7 and a mounting bracket 9. The guiding structure 7 is connected to the connecting component 1 and the mounting bracket 9 respectively. By providing the guiding structure 7, the guiding effect of the vertical movement of the connecting component 1 can be realized, ensuring the stability of the vertical movement of the connecting component 1. It can be understood that the guiding structure 7 extends in the vertical direction, and the mounting bracket 9 is used to support the guiding structure 7. The mounting bracket 9 can be mounted on the skeleton of the instrument panel 8.

[0284] Optionally, in an embodiment of the present disclosure, the guiding structure 7 includes a slide rail 71 and a slider 72. The slider 72 is slidably connected to the slide rail 71. One of the slide rail 71 and the slider 72 is connected to the mounting bracket 9, and the other is connected to the connecting component 1.

[0285] Among them, the slide rail 71 is used to guide the slider 72. The slide rail 71 is arranged in the vertical direction, and the slider 72 can slide up and down on the slide rail 71. By being connected to the mounting bracket 9 and the connecting component 1 respectively, the mounting bracket 9 and the connecting component 1 can slide relative to each other. The limiting effect of the slide rail 71 produces a guiding and limiting effect, which can limit the movement of the connecting component 1 in the vertical direction and ensure the movement stability. In some examples, the slide rail 71 is connected to the mounting bracket 9, and the slider 72 is connected to the connecting component 1.

[0286] Optionally, in another embodiment of the present disclosure, the guiding structure 7 includes a chute and a slider. The slider is slidably connected in the chute. The chute extends in the vertical direction. The slider is arranged on the outer side wall of the connecting component 1, and the chute is arranged on the mounting bracket 9.

[0287] Optionally, in an embodiment of the present disclosure, a recessed portion that is recessed upward is provided at the bottom of the instrument panel 8. In the folded state, at least a part of the steering wheel 2 is located in the recessed portion. By providing the recessed portion, the steering wheel 2 can be accommodated, so that the steering wheel 2 can be as close to the instrument panel 8 as possible, thereby avoiding excessive occupation of the leg space in the driver's cab and ensuring the comfort of the driver. It can be understood that, in some examples, after the steering wheel 2 is rotated and folded, the connecting assembly 1 drives the steering wheel 2 to move below the instrument panel 8. At this time, the connecting assembly 1 can move upward to drive the steering wheel 2 to move upward and be accommodated in the recessed portion.

[0288] Optionally, in another embodiment of the present disclosure, an extension portion that extends downward is formed on one side of the instrument panel 8 facing the driver's seat of the vehicle. In the folded state, the extension portion is used to block at least a part of the steering wheel 2. By providing the extension portion, after the steering wheel 2 is retracted below the instrument panel 8, the steering wheel 2 can be blocked, so that the steering wheel 2 is hidden, which can improve the aesthetics.

[0289] Optionally, in another embodiment of the present disclosure, a recessed portion that is recessed upward is provided at the bottom of the instrument panel 8. In the folded state, at least a part of the steering wheel 2 is located in the recessed portion, and an extension portion that extends downward is formed on one side of the instrument panel 8 facing the driver's seat of the vehicle. In the folded state, the extension portion is used to block at least a part of the steering wheel 2. By providing the recessed portion, the steering wheel 2 can be accommodated, so that the steering wheel 2 can be as close to the instrument panel 8 as possible, thereby avoiding excessive occupation of the leg space in the driver's cab and ensuring the comfort of the driver. It can be understood that, in some examples, after the steering wheel 2 is rotated and folded, the connecting assembly 1 drives the steering wheel 2 to move below the instrument panel 8. At this time, the connecting assembly 1 can move upward to drive the steering wheel 2 to move upward and be accommodated in the recessed portion. Then, the steering wheel 2 can be blocked by the extension portion, so that the steering wheel 2 is hidden, which can improve the aesthetics.

[0290] Optionally, in an embodiment of the present disclosure, during the process of switching from the unfolded state to the folded state, the movement state of the steering wheel 2 includes a rotation state in which the steering wheel 2 rotates around a first direction, and the first direction extends along the width direction of the vehicle. By rotating the steering wheel 2 around the first direction, the rotation and folding of the steering wheel 2 can be realized.

[0291] Optionally, in an embodiment of the present disclosure, during the process of switching from the unfolded state to the folded state, the movement state of the steering wheel 2 further includes at least one of a descending state in which the steering wheel 2 moves downward, a retracting state in which the steering wheel 2 moves forward, and an ascending state in which the steering wheel 2 moves upward.

[0292] Among them, in the descending state in which the steering wheel 2 moves downward, the steering wheel 2 can move downward, which is beneficial to the steering wheel 2 rotating around the first direction to avoid interference, and is also beneficial to the steering wheel 2 moving forward to avoid interference.

[0293] Among them, in the retracted state where the steering wheel 2 moves forward, the steering wheel 2 can move forward and can be retracted as much as possible under the instrument panel 8, and the steering wheel 2 can be completely retracted under the instrument panel 8.

[0294] Among them, in the ascending state where the steering wheel 2 moves upward, after the steering wheel 2 is retracted under the instrument panel 8, the steering wheel 2 can move upward and can fit under the instrument panel 8, reducing the occupation of the leg space. It can be understood that during the process of switching from the folded state to the unfolded state, the movement state of the steering wheel 2 is opposite to the movement state of the steering wheel 2 during the process of switching from the unfolded state to the folded state.

[0295] Optionally, in an embodiment of the present disclosure, the steering wheel 2 sequentially passes through a rotating state and a retracting state to switch from the unfolded state to the folded state. It can be understood that the steering wheel 2 can be switched from the unfolded state to the folded state by rotating around the first direction and moving forward, that is, retracting the steering wheel 2 under the instrument panel 8.

[0296] Optionally, in an embodiment of the present disclosure, the steering wheel 2 sequentially passes through a descending state, a rotating state, a retracting state, and an ascending state to switch from the unfolded state to the folded state. It can be understood that the movement process of the steering wheel 2 is that the steering wheel 2 first descends, then rotates around the first direction, then moves forward, and then moves upward to fit under the instrument panel 8, and can be switched from the unfolded state to the folded state, that is, retracting the steering wheel 2 under the instrument panel 8.

[0297] Optionally, in an embodiment of the present disclosure, the steering wheel 2 sequentially passes through a rotating state, a descending state, a retracting state, and an ascending state to switch from the unfolded state to the folded state. It can be understood that the movement process of the steering wheel 2 is that the steering wheel 2 first rotates around the first direction, then descends, then moves forward, and then moves upward to fit under the instrument panel 8, and can be switched from the unfolded state to the folded state, that is, retracting the steering wheel 2 under the instrument panel 8.

[0298] Among them, the steering wheel 2 is connected to the connecting component 1. The steering wheel 2 can rotate relative to the connecting component 1 around the first direction, and then when the connecting component 1 moves, the steering wheel 2 can be driven to move synchronously, thereby realizing the position change of the steering wheel 2, and enabling the steering device to switch between the unfolded state and the folded state.

[0299] Optionally, in an embodiment of the present disclosure, a through hole 81 is provided on the instrument panel 8. In the unfolded state, the steering wheel 2 is located directly behind the through hole 81.

[0300] Among them, in the unfolded state, the steering wheel 2 is located behind the instrument panel 8. At this time, the steering wheel 2 can produce a certain shielding effect, and can shield at least part of the through-hole 81.

[0301] The steering device further includes a closing member 31. In the unfolded state, the closing member 31 at least partially opens the through-hole 81. In the folded state, the closing member 31 closes the through-hole 81. In the folded state, the steering wheel 2 is located below the instrument panel 8, and the through-hole 81 is opened. By closing the through-hole 81 through the closing member 31, it is possible to prevent the structures inside the instrument panel 8 from being exposed through the through-hole 81, improving the aesthetics.

[0302] Among them, in some examples, in the unfolded state, the closing member 31 is located at the first position. During the process of switching from the unfolded state to the folded state, the closing member 31 first moves in the left-right direction to the second position, and then moves from the second position to the third position to close the through-hole 81. It can be understood that the closing member 31 includes two moving processes. First, it moves in the left-right direction, and then moves backward to the through-hole 81 to close the through-hole 81. With such a setting, the connecting component 1 can be avoided and interference with the connecting component 1 can be prevented.

[0303] Among them, in other examples, during the process of switching from the unfolded state to the folded state, the closing member 31 moves obliquely backward from the first position to the third position. It can be understood that the closing member 31 moves obliquely and directly moves to the through-hole 81 to close the through-hole 81. With such a setting, the connecting component 1 can also be avoided and interference with the connecting component 1 can be prevented.

[0304] Optionally, the first position is located inside the instrument panel 8, and the second position is located at the through-hole 81 opened on the instrument panel 8.

[0305] Please refer to Figure 23 , taking the column as the connecting component as an example, the adjustment process for the steering wheel to be adjusted to the folded state can be as follows:

[0306] The descent of the column drives the steering wheel to descend (appropriately avoiding the instrument panel to prevent affecting subsequent flipping);

[0307] The whole steering wheel rotates along the axis in the vehicle width direction; [[ID=E24]]

[0308] The column contracts along the vehicle length direction;

[0309] The slide cover is closed to ensure the aesthetics of the instrument panel after the steering wheel is stored;

[0310] The column is lifted to make the steering wheel close to the bottom of the instrument panel to achieve the maximum storage effect.

[0311] In some embodiments, please refer to Figure 1 and Figure 17, the steering device 200 further includes a rotating shaft 4b and a locking assembly 10. The rotating shaft 4b is relatively fixed to the steering wheel 2. The rotating shaft 4b can rotate in a first direction to drive the steering wheel 2 to rotate. By way of example, the rotating shaft 4b can be the first rotating shaft 41b or the second rotating shaft 41.

[0312] The locking assembly 10 has a locked state and an unlocked state. When the locking assembly 10 is in the locked state, the locking assembly 10 locks the rotating shaft 4b. When the locking assembly 10 is in the unlocked state, the locking assembly 10 unlocks the rotating shaft 4b.

[0313] When the steering wheel 2 needs to be switched between a folded state and an unfolded state, the locking assembly 10 can be placed in the unlocked state to facilitate the rotation of the rotating shaft 4b, thereby facilitating the switching of the steering wheel 2 between the folded state and the unfolded state. When the steering wheel 2 is switched to the folded state or the unfolded state, the rotating shaft 4b can be locked by the locking assembly 10 to prevent the rotating shaft 4b from rotating and improve the stability of the steering wheel 2.

[0314] In some embodiments, the locking assembly 10 includes a first locking member 101 and a second locking member 102. The first locking member 101 is connected to the rotating shaft 4b. The second locking member 102 can move toward or away from the first locking member 101. When the locking assembly 10 is in the locked state, the second locking member 102 is engaged with the first locking member 101. When the locking assembly 10 is in the unlocked state, the second locking member 102 is separated from the first locking member 101.

[0315] By engaging or separating the first locking member 101 and the second locking member 102, the switching between the locked state and the unlocked state of the locking assembly 10 can be achieved, which can make the structure of the locking assembly 10 relatively simple and thus facilitate the operation of the locking assembly 10.

[0316] In some examples, the first locking member 101 can be a gear 621, and the second locking member 102 can be an arc-shaped structure provided with teeth. When the second locking member 102 is engaged with the first locking member 101, the teeth of the second locking member 102 are meshed with the teeth of the first locking member 101. Since the second locking member 102 cannot rotate, the rotation of the second locking member 102 can be restricted, thereby restricting the rotation of the rotating shaft 4b. The separation of the first locking member 101 and the second locking member 102 means the separation of their teeth.

[0317] In some other examples, the first locking member 101 can also be a block structure connected to the rotating shaft 4b. A clamping groove is provided on the block structure. The second locking member 102 can be a rod-shaped structure. The first locking member 101 and the second locking member 102 are clamped by moving a part of the second locking member 102 into the clamping groove. When the second locking member 102 withdraws from the clamping groove, the first locking member 101 and the second locking member 102 are separated.

[0318] In some embodiments, the steering device 200 further includes a base 106, and the second locking member 102 is rotatably connected to the base 106. For example, when the rotating shaft 4b is the first rotating shaft 41b, the base 106 can be connected to the connecting assembly 1. In another example, when the rotating shaft 4b is the second rotating shaft 41, the base 106 can be the support base 21.

[0319] By rotatably connecting the second locking member 102 to the base 106, it is convenient to control the movement of the second locking member 102, thereby facilitating the clamping or separation of the second locking member 102 and the first locking member 101.

[0320] In some embodiments, the locking assembly 10 further includes a locking driving member 103, and the locking driving member 103 is in transmission connection with the second locking member 102 to drive the second locking member 102 to move towards the first locking member 101. The locking driving member 103 can be a motor or the like, and the locking driving member 103 can be connected to the base 106.

[0321] By driving the second locking member 102 to move through the locking driving member 103, it is convenient to control the second locking member 102, thereby facilitating the operation of the locking assembly 10.

[0322] In some embodiments, the locking assembly 10 further includes a locking pin 104. The locking pin 104 is connected to the locking driving member 103, and the locking driving member 103 is used to drive the locking pin 104 to move so that the locking pin 104 pushes the second locking member 102 towards the first locking member 101.

[0323] For example, the locking pin 104 can move along the rotation direction of the second locking member 102 to drive the second locking member 102 to rotate, realizing the clamping of the second locking member 102 and the first locking member 101. In another example, the locking pin 104 can also move in the direction of the rotation axis of the second locking member 102. When the locking pin 104 moves to the side of the second locking member 102 facing away from the first locking member 101 and contacts the second locking member 102, it can generate a thrust towards the first locking member 101 on the second locking member 102 to drive the second locking member 102 and the first locking member 101 to be clamped.

[0324] By providing the locking pin 104, it is convenient to drive the second locking member 102 to move, and it is also convenient for the spatial arrangement of the locking driving member 103, the first locking member 101 and the second locking member 102, so as to make rational use of the space.

[0325] In some embodiments, the locking assembly 10 further includes an elastic member 105, which is connected between the base 106 and the second locking member 102 and is used to provide an elastic force for the second locking member 102 to move away from the first locking member 101. For example, the elastic member 105 can be a columnar spring, a rubber member, a latex member, a silica gel member, etc. The present application does not make specific limitations on this.

[0326] By providing the elastic member 105, it is convenient for the second locking member 102 to separate from the first locking member 101, so as to facilitate unlocking of the locking assembly 10 and facilitate the operation of the locking assembly 10.

[0327] In some embodiments, at least one of the driving device and the locking driving member 103 is a Hall motor. When the driving device is a Hall motor, relatively precise control of the state adjustment of the steering wheel 2 can be achieved, and the state adjustment process of the steering wheel 2 can be made relatively stable. When the locking driving member 103 is a Hall motor, the movement of the second locking member 102 can be relatively precise and stable. In some embodiments, the steering device 200 may further include a first airbag, which is disposed in the steering wheel 2, and when the first airbag is deployed, the connecting assembly 1 of the steering device 200 moves downward. In this way, when the first airbag is deployed, the downward movement of the connecting assembly 1 can avoid the first airbag, so that the first airbag can be deployed smoothly and can effectively protect the driver.

[0328] Among them, the bag shape of the airbag of the first airbag can be set so that the airbag can also contact the instrument panel after the first airbag is deployed, so as to achieve a better protection effect.

[0329] In some embodiments, the steering device 200 further includes a second airbag and a third airbag. The second airbag is disposed on the instrument panel 8, and the third airbag is disposed in the connecting assembly 1 of the steering device 200. In this way, the position of the third airbag is lower than that of the second airbag and is basically aligned with the knee position of the driver. In the event of a collision, the second airbag can protect the upper body of the driver, and the third airbag can protect the lower body of the driver, thereby improving the protection effect on the driver.

[0330] In some embodiments, the steering device 200 further includes a fourth airbag, and the fourth airbag is disposed on the door or the center console. In this way, when the vehicle 100 collides, the fourth airbag can pop out from the side of the driver to protect the driver. Thus, regardless of whether the steering wheel 2 is in a folded state or an unfolded state, the deployment of the fourth airbag can be unaffected by the state of the steering wheel 2, so that the fourth airbag can effectively protect the driver.

[0331] Among them, it is possible to set that the airbag cover and the box body of the fourth airbag can expand a wider space to both sides, which is used to support the fourth airbag to protect the driver, so as to improve the protection effect.

[0332] In some embodiments, the steering device 200 further includes a fifth airbag, and the fifth airbag is disposed on the top of the vehicle body 20. For example, the side curtain airbag, the far-side airbag, and the frontal airbag are integrated into one to form the fifth airbag, which is arranged on the roof. When a collision occurs, the fifth airbag unfolds from top to bottom and has both side and frontal protection effects. In this way, the fifth airbag can also effectively protect the driver and can avoid the influence of the steering wheel 2.

[0333] In some embodiments, the steering device 200 further includes a sixth airbag, and the sixth airbag is disposed on the backrest of the seat. In this way, the sixth airbag can protect the driver from the rear side of the driver. When the driver's sitting posture is abnormal during a collision, it can effectively protect the driver and reduce the damage suffered by the driver.

[0334] Among them, Scenario 1: The airbag does not fold with the steering wheel 2. At this time, the driver's airbag loses the support of the steering wheel 2, and the protection performance of the airbag for the driver is reduced when it deploys during a collision. At the same time, there is a risk that the person's head will slide out of the edge of the airbag; Countermeasures: ① When the airbag detonates, the column shrinks away from the driver, uses the instrument panel for support, and at the same time leaves more buffer space for the driver; ② Install the airbag inside the instrument panel or the steering housing. When the steering wheel 2 folds, detonate the two airbags simultaneously to support the driver's airbag; ③ The airbag deploys from the side (inside the door or the center console), and the airbag should be able to automatically adjust its front and rear positions according to the occupant's sitting posture and physical signs; ④ When the steering wheel 2 folds towards the knee position, it blocks the knee space. If a knee airbag needs to be configured at this time, the airbag in Countermeasure ② should have the function of supporting the front airbag and should also have the function of knee protection; ⑤ When the steering wheel 2 folds towards the knee position and blocks the knee space, the driver's airbag can be designed to have the functions of head and chest protection and knee protection at the same time; ⑥ Design the bag shape of the airbag so that the airbag can also contact the instrument panel after deployment to achieve normal protection effect; ⑦ Design the airbag cover and the box body to be able to expand wider space to both sides to support the airbag to protect the occupant; ⑧ Integrate the side curtain airbag, the distal airbag, and the front airbag and arrange them in the ceiling, and deploy from top to bottom, with both side and front protection effects

[0335] Scenario 2: The driver's airbag folds with the steering wheel 2. ① In the normal unfolded state, the airbag should be able to deploy normally. When the airbag and the steering wheel 2 are in the folded state, the airbag should be able to quickly return to the normal position when detecting a collision to achieve the protection effect. With the assistance of active safety, the airbag should be able to return to the normal position within 1 second through the motor, or quickly return to the normal position through the force generated during detonation; ② The airbag has the ability to deploy normally in the normal position and change the deployment direction in the folded position, realized through the airbag and the guide cloth or the pull belt; ③ After folding, it deploys in the way of combining the knee airbag and the front head airbag (realized by rotating the airbag inside the airbag and the guide)

[0336] Scenario 3: Protection solutions for occupants in abnormal sitting postures under the action of intelligent driving and intelligent steering. ① Combine Solution ⑧ in Scenario 1 and add a backrest airbag at the same time to jointly protect the safety of the driver when the occupant is in an abnormal sitting posture

[0337] Scenario Extension 4: ① When steering smartly, the data collection through the by-wire system can construct the driving behavior characteristics of the driver. At the same time, combined with the customizable dimensions such as the weight and height of the vehicle occupants, an airbag control strategy that provides the best protection effect for the users can be customized, mainly reflected in the adjustment of the ignition moment. ② When the airbag in the steering system can be folded, the front space may be used for office work or placing items such as water cups. At this time, the airbag deployment path should be designed not to pass through the front directly. At the same time, the in-vehicle camera is used to judge the in-vehicle state, and the position and deployment strategy of the airbag are adjusted in real time. When necessary, the user is warned or reminded. ③ When the vehicle 100 is stationary, the user may need to rest in the vehicle. When the user needs to lie on the instrument panel to rest, the airbag should be able to be taken out and inflated as a pillow or a cushion, or used as a quilt. After use, it should be able to deflate and be simply folded and retracted without affecting the function of detonating to protect the occupants during a collision.

[0338] In some possible embodiments of the present application, the steering device 200 can achieve self-locking or locking.

[0339] Optionally, the steering device 200 adopts a movable locking buckle, which can freely control the locked or unlocked state through a control chip and software, and can control the angular position of the locking of the rotating shaft 4b to achieve multi-stage locking of the rotating shaft 4b.

[0340] In some possible embodiments, the locking can be achieved in the following ways:

[0341] Steering wheel anti-pinch motor: including a base 106, a motor, a Hall and a main control ECU, a rotating shaft 4b, a locking pin 104, a locking buckle, and a spring

[0342] Control unit: Receives sensor signals, processes data, and controls the motor action.

[0343] Motor: Responsible for driving the limit buckle to achieve the switching between the locked and unlocked states.

[0344] Working principle: The rotating shaft 4b is provided with a gear 621, which meshes with the gear 621 on the locking buckle. The locking buckle is fixed on the base 106 and cannot rotate with the rotating shaft 4b, so as to achieve the locking of the rotating shaft 4b. This locking structure also includes a driving motor and a spring. The locking pin 104 provides pressure to make the locking buckle and the rotating shaft 4b fit tightly, ensuring the locking effect and providing the stability and reliability of the system. When the rotating shaft 4b needs to rotate, the driving motor drives the locking pin 104 to disengage from the locking position and move under the action of the spring, so that the locking buckle disengages from the gear 621 of the rotating shaft 4b. The rotation of the rotating shaft 4b is not blocked and rotates normally. After moving to the required position, the driving motor rotates back, and the locking pin 104 and the locking buckle re-engage with the gear 621 of the rotating shaft 4b, and the rotating shaft 4b resumes the locked state.

[0345] In some other possible embodiments, the locking can be achieved in the following ways:

[0346] Structural mechanism components: including a motor, a Hall element, and a main control ECU, a rotating shaft 4b, a locking pin 104, a locking buckle, and a spring, which control the state of the rotating shaft 4b before or during the execution of an action.

[0347] Control unit: receives sensor signals, processes data, and controls the operation of the motor.

[0348] Motor: responsible for driving the folding and unfolding of the steering wheel.

[0349] Working principle: Motor control: To ensure the accurate meshing of the locking mechanism and the gear 621 of the rotating shaft 4b, it is necessary to control the angles of the rotating shaft 4b and the locking buckle to keep the two mechanisms tightly meshed. The driving of the rotating shaft 4b and the driving electricity of the locking structure are both Hall motors, and the movement angle is controlled by the main control ECU.

[0350] In some embodiments, the vehicle 100 further includes a driver's seat, and the vehicle 100 is configured to drive the driver's seat to move away from the steering wheel 2 during the folding process of the steering wheel 2 until the driver's seat moves to a predetermined position. In this way, interference from the driver's seat during the folding process of the steering wheel 2 can be avoided to ensure that the steering wheel 2 can be folded smoothly.

[0351] In some embodiments, when the vehicle 100 meets the first condition, the steering wheel 2 is allowed to switch to the folded state or remain in the folded state; wherein, the first condition includes one or more of the following:

[0352] The vehicle 100 is in a stationary state;

[0353] The gear of the vehicle 100 is in the parking gear or the parking position;

[0354] The vehicle 100 is in a power-off state;

[0355] The vehicle 100 receives a locking instruction;

[0356] The driver's door of the vehicle 100 is switched from the closed state to the open state based on an in-vehicle operation;

[0357] The vehicle 100 detects that the driver gets out of the vehicle;

[0358] When the vehicle 100 is in a driving state, it is in a second driving state, and the second driving state is an autonomous driving state in which the vehicle 100 meets the requirements of autonomous driving.

[0359] When the steering wheel 2 is in a state where it is not needed, the steering wheel 2 can be placed in a folded state, so as to release more activity space for the driver and improve the driver's riding experience.

[0360] In some embodiments, when the vehicle 100 meets the first condition, the steering wheel 2 automatically switches to the folded state or remains in the folded state. This can free the driver's hands and make the state switching of the steering wheel 2 more convenient. For example, when parking, the steering wheel 2 can be automatically folded, and when the driver gets out of the vehicle, the steering wheel 2 can also be automatically folded.

[0361] In some embodiments, when the vehicle 100 meets the first condition, the steering wheel 2 is switched to the folded state through manual operation; the manual operation includes at least one of the following: receiving a folding instruction, the user manually folds the steering wheel 2, and detecting that the user's hand is not placed on the steering wheel 2. Folding the steering wheel 2 through manual operation can enable the driver to experience the fun of operation, and compared with automatic switching, the user operation is more direct, which can save electric energy and can also achieve folding in the case of power failure.

[0362] In some embodiments, when the vehicle 100 meets the second condition, the steering wheel 2 is configured to automatically switch to the unfolded state or remain in the unfolded state. This can make the switching of the steering wheel 2 to the unfolded state more convenient.

[0363] In some embodiments, when the vehicle 100 meets the second condition, the steering device 200 gives a reminder through the vehicle 100 to switch the steering wheel 2 to the unfolded state or keep the steering wheel 2 in the unfolded state. This can enable the driver to timely switch the steering wheel 2 to the turned-on state, thereby facilitating the operation of the steering wheel 2 and reducing the occurrence of accidents.

[0364] Wherein, the second condition includes one or more of the following:

[0365] The vehicle 100 receives an unlocking instruction;

[0366] The vehicle 100 receives a power-on instruction;

[0367] The vehicle 100 receives a driving instruction;

[0368] The vehicle 100 receives an instruction to open the driver's door;

[0369] The vehicle 100 detects that the driver gets on the vehicle;

[0370] The driver's door of the vehicle 100 is opened;

[0371] The driver's seat of the vehicle 100 detects that there is a person sitting;

[0372] The vehicle 100 is in the first driving state;

[0373] The vehicle 100 has a network anomaly;

[0374] The component state of the steering device 200 is abnormal;

[0375] The remaining energy of the vehicle 100 is lower than a set threshold, and the remaining energy is the energy capable of driving the vehicle 100;

[0376] The vehicle 100 switches to or is in a driving state, and the driving state includes that the gear of the vehicle 100 is not in the P gear, the gear of the vehicle 100 is in the D gear, or the gear of the vehicle 100 is in the R gear, or the vehicle speed of the vehicle 100 is greater than 0.

[0377] The driver may use the steering wheel 2, and switching the steering wheel 2 to the deployed state when the vehicle 100 meets the above conditions can facilitate the driver's use of the steering wheel 2.

[0378] In some embodiments, when the vehicle 100 is in a state of driving based on an intelligent driving system, the vehicle 100 switches between the deployed state and the folded state according to the state of the intelligent driving system. For example, when the intelligent driving system can independently control the vehicle 100 to drive and achieve autonomous driving, it can automatically fold the steering wheel 2 or remind the user to fold the steering wheel 2; in the event of an emergency or poor traffic conditions, it can automatically deploy the steering wheel 2 or remind the user to take over the driving operation or remind the user to deploy the steering wheel 2.

[0379] In some embodiments, the steering wheel 2 is configured to adjust the steering wheel 2 to the deployed state or the folded state based on a switching control strategy corresponding to the driving mode of the vehicle 100, and the driving mode includes an autonomous driving mode or a non-autonomous driving mode.

[0380] In some embodiments, when the vehicle 100 is in a stationary state, the vehicle 100 gear is in the parking gear, and the vehicle 100 power supply is turned off, the steering wheel 2 is allowed to automatically switch from the deployed state to the folded state. In the above state, the driver basically does not use the steering wheel 2, so making the steering wheel 2 in the folded state can release space to improve the driver's driving and riding experience.

[0381] When the vehicle 100 is in a stationary state, the gear of the vehicle 100 is in the parking gear, and the power supply of the vehicle 100 is turned on, it is allowed for the steering wheel 2 to switch from the deployed state to the folded state in response to a user's control instruction. When the power supply is turned on, the driver may start the vehicle 100 to drive at any time. At this time, enabling the steering wheel 2 to switch from the deployed state to the folded state in response to a user's control instruction allows the user to adjust the steering wheel 2, improving the flexibility of the state switching of the steering wheel 2.

[0382] When the vehicle 100 is in a non-parking gear or the vehicle speed of the vehicle 100 is not zero, it is not allowed for the steering wheel 2 to switch from the deployed state to the folded state. At this time, it is necessary to adjust the driving direction of the vehicle 100 through the steering wheel 2, keeping the steering wheel 2 always in the deployed state, which can facilitate the driver to operate the steering wheel 2.

[0383] When the state information of the vehicle 100 does not meet the folding condition, it is not allowed for the steering wheel 2 to switch from the deployed state to the folded state. This can avoid accidents or dangers caused by the steering wheel 2 being in the folded state.

[0384] In some embodiments, the switching control strategy corresponding to the autonomous driving mode includes at least one of the following:

[0385] When the vehicle 100 is in a stationary state, the gear of the vehicle 100 is in the parking gear, and the power supply of the vehicle 100 is turned off, it is allowed for the steering wheel 2 to automatically switch from the deployed state to the folded state. In the above state, the driver basically does not use the steering wheel 2. Therefore, keeping the steering wheel 2 in the folded state can release space, improving the driving experience of the driver.

[0386] When the vehicle 100 is in a stationary state, the gear of the vehicle 100 is in the parking gear, and the power supply of the vehicle 100 is turned on, it is allowed for the steering wheel 2 to switch from the deployed state to the folded state in response to a user's control instruction. When the power supply is turned on, the driver may start the vehicle 100 to drive at any time. At this time, enabling the steering wheel 2 to switch from the deployed state to the folded state in response to a user's control instruction allows the user to adjust the steering wheel 2, improving the flexibility of the state switching of the steering wheel 2

[0387] When the vehicle 100 is in a non-parking gear or the vehicle speed of the vehicle 100 is not zero, it is allowed for the steering wheel 2 to switch from the deployed state to the folded state. At this time, the vehicle 100 is in the autonomous driving state, and the driver can not use the steering wheel 2. Therefore, it is allowed for the steering wheel 2 to switch to the folded state, providing a larger activity space for the driver and improving the driving experience.

[0388] When the status information of the vehicle 100 does not meet the folding condition, it is not allowed to switch the steering wheel 2 from the unfolded state to the folded state. This can avoid accidents or dangers caused by the steering wheel 2 being in the folded state.

[0389] In some embodiments, the folding condition includes at least one of the following:

[0390] The network of the vehicle 100 is in a normal state;

[0391] The remaining energy of the vehicle 100 is greater than or equal to a preset threshold;

[0392] The steering device 200 has not failed.

[0393] A normal network can ensure that the steering device 200 can receive instructions normally, so that the folding of the steering wheel 2 can be controlled smoothly. The remaining energy can be, for example, the remaining battery power. The battery power being greater than the preset threshold can ensure that the driving device has sufficient power to ensure that the steering wheel 2 can be folded smoothly. The steering device 200 not failing can also ensure that the steering wheel 2 can be folded smoothly.

[0394] In some embodiments, the steering device 200 further includes a road feel simulation unit, and the road feel simulation unit is used to provide a self-aligning torque to the steering wheel 2. By obtaining the self-aligning torque through the road feel simulation unit, the driver can conveniently know the running condition of the vehicle 100, so as to timely control the vehicle 100 when the vehicle 100 is unstable and ensure the driving stability of the vehicle 100.

[0395] In some embodiments, the self-aligning torque provided by the road feel simulation unit to the steering wheel 2 is determined based on an initial self-aligning torque and a feel coefficient. In this way, a more accurate self-aligning torque can be obtained so that the driver can accurately control the vehicle 100.

[0396] In some embodiments, the feel coefficient is determined according to the driver's preference. In this way, the feedback self-aligning torque can better conform to the driver's driving habits and improve the driver's driving experience.

[0397] In some embodiments, the feel coefficient includes a feel coefficient in the sport mode and a feel coefficient in the comfort mode.

[0398] In some embodiments, the initial self-aligning torque is determined based on at least one of a first self-aligning torque, a second self-aligning torque, and a third self-aligning torque; wherein, the first self-aligning torque is the self-aligning torque generated by the friction between the tire and the ground, the second self-aligning torque is the self-aligning torque generated by the steering wheel alignment parameters, and the third self-aligning torque is the self-aligning torque caused by steering inertia.

[0399] In this way, the return moment when going back can be made more accurate, so that the driver can control the vehicle 100 more accurately.

[0400] In some embodiments, the road feeling simulation unit is further configured to vibrate the steering wheel 2. In this way, when the vehicle 100 becomes unstable, the driver can be aware of it immediately, so as to control the vehicle 100 in time and reduce the danger.

[0401] In some embodiments, the steering device 200 is configured to control the road feeling simulation unit to vibrate the steering wheel 2 when the vehicle 100 has a risk of instability or when the vehicle 100 drives from a high-adhesion road surface to a low-adhesion road surface. The above situations will cause the vehicle 100 to drive unstably. At this time, vibrating the steering wheel 2 through the road feeling simulation unit can remind the driver, so that the driver can control the vehicle 100 in time and avoid danger.

[0402] In some embodiments, in the presence of a folding obstacle state, the steering device 200 stops performing the folding action or the steering wheel 2 remains in the unfolded state. When there is a folding obstacle state, if the steering wheel 2 is folded, it may cause the steering wheel 2 to squeeze the obstacle, resulting in damage to the steering wheel 2 or the obstacle. Therefore, stopping the folding action or keeping the steering wheel 2 in the unfolded state in the folding obstacle state can ensure the safety of the steering wheel 2 or other components and personnel.

[0403] In some embodiments, in the presence of a folding obstacle state, the vehicle 100 and / or the steering device 200 is configured to perform an avoidance action. For example, when there is a folding obstacle state, the driving device controls the steering wheel 2 to change the moving trajectory to avoid the steering wheel 2 squeezing the obstacle, thereby improving safety.

[0404] Among them, the folding obstacle state includes one or more of the following:

[0405] There is an obstacle in the folding path area, and the folding path area includes:

[0406] The area that the steering wheel 2 needs to pass through when being folded; or

[0407] The area that the steering device 200 needs to pass through to complete the remaining folding action.

[0408] In some embodiments, when the following conditions are met, the vehicle 100 detects whether there is a folding obstacle:

[0409] The steering wheel 2 is in the off-hand state;

[0410] The steering device 200 meets the first condition for being allowed to fold;

[0411] The vehicle 100 or the steering device 200 receives a folding instruction;

[0412] The steering device 200 is performing the folding action.

[0413] In some embodiments, the avoidance action includes at least one of the following:

[0414] Adjust the seat;

[0415] Change the folding path.

[0416] Adjusting the seat may cause interference between the steering wheel 2 and the seat or between the latter and the driver, resulting in a collision between the steering wheel 2 and the seat or the driver, thus posing a danger. Changing the folding path of the steering wheel may also cause a collision or extrusion between the steering wheel 2 and other components, resulting in a danger.

[0417] In some embodiments, the vehicle 100 or the steering device 200 is configured to issue a warning in the presence of a folding obstacle state. In this way, the driver can be reminded when there is a folding state, so that the driver can intervene in time, thereby reducing the occurrence of danger.

[0418] In some embodiments, the steering device 200 further includes a hand-off detection module, and the hand-off detection device is used to determine whether the steering wheel 2 is in a hand-off state. In this way, when the steering wheel 2 is folded, it can be avoided that the driver's hand is located in the area where the steering wheel 2 needs to pass, thus avoiding squeezing the driver's hand and avoiding injury to the driver, improving safety.

[0419] The anti-pinch function of the folding of the steering wheel 2 can be realized in combination with relevant systems on the vehicle 100.

[0420] In a possible embodiment, the anti-pinch function is realized in the following way:

[0421] By-wire steering system: It includes a torque sensor and a main control ECU, integrated into the by-wire steering. Before or during the execution of the action of folding the steering wheel, in the case of the failure of the capacitive induction and anti-pinch motor of the steering wheel, when the actual anti-pinch force value is generated, the product displacement causes the product angle to rotate, and it is used to detect whether the rotation of the steering wheel is affected by an external force obstacle, and to judge whether it is necessary to stop the current folding / unfolding action.

[0422] Driver Monitor System (DMS): It includes a camera and a main control ECU, which are integrated into the whole vehicle. When the folding steering wheel is about to perform an action or during the action execution, and in the case of capacitive sensing of the steering wheel, anti-pinch motor, and steer-by-wire steering wheel detection, it can, when the anti-pinch force value is actually generated before and after, through visual compensation, detect whether there are obstacles affecting the folding / unfolding movement trajectory during the folding / unfolding process of the steering wheel, and determine whether to stop the current folding / unfolding action.

[0423] Seat: By receiving signals from the vehicle body 20 controller or the steering wheel ECU, it moves backward to create a safe distance for the driver from the folding / unfolding of the steering wheel, avoiding the occurrence of anti-pinch working conditions and reducing the occurrence frequency.

[0424] Vehicle body 20 controller / Steering wheel ECU: Receives sensor signals, processes data, and controls the motor actions.

[0425] Motor: Responsible for driving the folding and unfolding of the steering wheel.

[0426] Alarm device: Emits audible and visual alarms when an obstacle is detected.

[0427] In another possible embodiment, anti-pinch is achieved in the following way:

[0428] Motor anti-pinch solution (Steering wheel motor)

[0429] System composition

[0430] Steering wheel anti-pinch motor system: It includes a motor, Hall, and main control ECU, which are integrated into the steering wheel assembly. During the execution of the folding action of the steering wheel, when the anti-pinch force value is actually generated, it is used to detect whether there are obstacles near the steering wheel and determine whether to stop the current folding / unfolding action. The motor is the motor that drives the steering wheel 2 to rotate in the first direction.

[0431] Control unit: Receives sensor signals, processes data, and controls the motor actions.

[0432] Motor: Responsible for driving the folding and unfolding of the steering wheel.

[0433] Alarm device: Emits audible and visual alarms when an obstacle is detected.

[0434] Working principle:

[0435] Motor: When the driver leaves the steering wheel, the hand-off detection module will immediately detect this state and send a signal to the control unit.

[0436] Obstacle detection: After receiving the hand-off signal, the control unit activates the sensor module to continuously monitor the area around the steering wheel. If an obstacle (such as a finger) is detected, the sensor will immediately send a signal to the control unit.

[0437] Motor control: After receiving the obstacle signal, the control unit immediately stops the folding action of the motor and reverses the motor to partially unfold the steering wheel to ensure that the obstacle will not be pinched.

[0438] Alarm prompt: At the same time, the alarm device is activated to emit an audible and visual alarm to remind the user to pay attention to safety.

[0439] In some other embodiments, anti-pinch is achieved in the following way:

[0440] Handoff detection module: It includes a capacitive sensor and a main control ECU, integrated in the steering wheel assembly. Before or during the folding action of the folding steering wheel, it can be used to detect whether there is an obstacle near the steering wheel without actually generating an anti-pinch force value, accurately identify whether it is a human torso, and determine whether to stop the current folding / unfolding action.

[0441] Control unit: Receives sensor signals, processes data, and controls the motor actions.

[0442] Motor: Responsible for driving the folding and unfolding of the steering wheel.

[0443] Alarm device: Emits an audible and visual alarm when an obstacle is detected.

[0444] Working principle

[0445] Handoff detection: When the driver leaves the steering wheel, the handoff detection module immediately detects this state and sends a signal to the control unit.

[0446] Obstacle detection: After receiving the hand-off signal, the control unit activates the sensor module to continuously monitor the area around the steering wheel. If an obstacle (such as a finger) is detected, the sensor will immediately send a signal to the control unit.

[0447] Motor control: After receiving the obstacle signal, the control unit immediately stops the folding action of the motor and reverses the motor to partially unfold the steering wheel to ensure that the obstacle will not be pinched.

[0448] Alarm prompt: At the same time, the alarm device is activated to emit an audible and visual alarm to remind the user to pay attention to safety.

[0449] In some other embodiments, anti-pinch is also achieved in the following way:

[0450] Steering wheel anti-pinch motor: It includes a motor, a Hall element and a main control ECU, which are integrated into the steering wheel assembly. During the folding operation of the steering wheel, when the actual anti-pinch force value is generated, it is used to detect whether there are obstacles near the steering wheel and determine whether to stop the current folding / unfolding operation.

[0451] Control unit: Receives sensor signals, processes data and controls the motor operation.

[0452] Motor: Responsible for driving the folding and unfolding of the steering wheel.

[0453] Alarm device: Emits sound and light alarms when an obstacle is detected.

[0454] Working principle

[0455] Anti-pinch motor: When the driver leaves the steering wheel, the hand-off detection module will immediately detect this state and send a signal to the control unit.

[0456] Obstacle detection: After receiving the hand-off signal, the control unit activates the sensor module to continuously monitor the area around the steering wheel. If an obstacle (such as a finger) is detected, the sensor will immediately send a signal to the control unit.

[0457] Motor control: After receiving the obstacle signal, the control unit immediately stops the folding operation of the motor and reverses the motor to partially unfold the steering wheel to ensure that the obstacle will not be pinched.

[0458] Alarm reminder: At the same time, the alarm device is activated to emit sound and light alarms to remind the user to pay attention to safety.

[0459] In some embodiments, refer to Figures 20 - 22 , it is possible to specify a road feel feedback coefficient for different roads based on road preview technology, improving driving safety and comfort.

[0460] Specifically, taking the original size of the input image as 1920*1080 as an example, redundant image information above and below the picture, as well as on the left and right sides, is removed respectively. The image range between the horizontal coordinates x1 = 200, x2 = 760, and the vertical coordinates y1 = 260, y2 = 420 pixels is taken. The intercepted effective road surface area is used for subsequent model training and prediction of the classification network. The classification model adopts the mature YOLOv5 model architecture.

[0461] The prior art scales the sample image with a resolution of 1920*1080 to 960*540. At the same time, considering that the image information determining the road surface category is mainly concentrated in the middle and lower parts of the image, the patent selects the area of 960*400 below the scaled image as the first image candidate area, and then performs subsequent image processing on this area.

[0462] The prior art only removes some redundant information from the upper part of the image. According to experiments, there is still a lot of redundant information that has not been processed. Our company's patent not only considers removing the redundant information in the upper and lower parts of the image, but also removes the redundant information in the left and right parts of the image, saving computing power and improving accuracy.

[0463] Then, the spatio-temporal alignment of multi-sensor data is carried out. Finally, based on the multi-modal fusion of Transformer, visual features, point cloud features and kinetic features are input into the Transformer model. A multi-layer Transformer Encoder is constructed, attention weights are assigned, and the final road surface adhesion coefficient is output by self-using feature weighting.

[0464] In some embodiments, the column itself can also be adjusted to adjust the height of the steering wheel 2. Among them, the adjustment stroke of the column is divided into a first stroke and a second stroke. The first stroke meets the adjustment requirements of the column itself, and the second stroke meets the storage function requirements of the steering wheel 2. The positions of the column are divided into a first position, a second position, a third position and a fourth position. The first position is the maximum value of the adjustment stroke of the column, the second position is the designed position of the column, the third position is the minimum value of the adjustment stroke of the column, and the fourth position is the minimum position of the storage stroke.

[0465] When the column adjustment function is triggered, first judge the current position of the column. When the column is between the first position and the third position, the column performs the corresponding adjustment action. When the column is between the third position and the fourth position, the column does not perform the adjustment action. When the storage of the steering wheel 2 is triggered during the adjustment of the column, the column continues to perform the adjustment function and does not perform the storage function, and feeds back to the driver in a certain way.

[0466] When the storage function of the steering wheel 2 is triggered, the column performs the storage action at all positions. When the column is between the third position and the fourth position, the column continues to perform the storage action and feeds back to the driver in a certain way. When the adjustment function is triggered during the storage process, the column continues to perform the storage action and does not perform the adjustment action, and feeds back to the driver in a certain way.

[0467] When the storage function and the adjustment function of the steering wheel 2 are triggered at the same time, the column only performs the adjustment function and feeds back to the driver in a certain way.

[0468] The storage function of the column and the column adjustment function share a set of motors. The motors have calibrated currents. During the process of the column performing the storage action and the adjustment action, if the motor current is greater than the calibrated current, it is judged that interference has occurred. At this time, the column stops the action being performed and feeds back to the driver in a certain way. When the action before stopping is triggered again, continue to perform the action.

[0469] In some embodiments, please refer toFigure 18 , the folding strategy process of the welcome steering wheel 2 is as follows:

[0470] Door locking signal → the handwheel 22 returns to the upright position → the column rotates downward from (-22.5 mm, B°) to (-22.5 mm, -4°) → the handwheel 22 is retracted to 70°, and at the same time the column continues to move forward to (-113 mm, -4°) → the handwheel 22 continues to be retracted to 85°.

[0471] The unfolding strategy process of the welcome steering wheel 2 is as follows:

[0472] Unlock signal → the handwheel 22 unfolds from 85° to 70° → driver's door open signal → the column rises from (-113 mm, -4°) to (-22.5 mm, -4°), and at the same time the handwheel 22 unfolds from 70° → the column rotates upward to (-22.5 mm, B°).

[0473] Note: According to feedback, the original column welcome position (-22.5 mm, +4°) needs to be adjusted. Temporarily replace it with (-22.5 mm, B°). The feel motor is configured with constant power. When folding, request to return to the correct direction. After returning to the correct position, actively lock to the 0 position. Considering energy consumption, directly decouple the steering motor. When powering on, automatically align to the folding signal → the handwheel 22 returns to the correct position → the handwheel 22 actively locks to the 0 position.

[0474] In some embodiments, please refer to Figure 19 , the folding strategy process of the externally displayed steering wheel 2 is as follows:

[0475] When the column is at 0—+4°, the steering wheel 2 returns to the correct position → the column rotates downward to (x, 0°) → the column moves forward to (-22.5 mm, 0°) → the column rotates downward to (-22.5 mm, -4°) → wait for the seat to reach the rear 1% position → the handwheel 22 is retracted to 70°, and at the same time the column continues to move forward to (-113 mm, -4°) → the handwheel 22 continues to be retracted to 85°.

[0476] When the column is at -4°—0°, the steering wheel 2 returns to the correct position → the column moves forward to (-22.5 mm, y°) → the column rotates downward to (-22.5 mm, -4°) → wait for the seat to reach the rear 1% position → the handwheel 22 is retracted to 70°, and at the same time the column continues to move forward to (-113 mm, -4°) → the handwheel 22 continues to be retracted to 85°.

[0477] The unfolding strategy process of the externally displayed steering wheel 2 is as follows:

[0478] When the pre - folding pipe column is at 0 - +4°, or when the pre - folding pipe column is at - 4° - 0°, when the seat reaches the rear 1% position → the handwheel 22 unfolds from 85° to 70° → the pipe column rises from (-113 mm, - 4°) to (-22.5 mm, - 4°), and at the same time the handwheel 22 unfolds from 70° (after unfolding, the seat synchronously returns to the default position) → the pipe column first turns upward to (-22.5 mm, 0°) → the pipe column continues to move backward to (x, 0°) → the pipe column turns upward to (x, y°).

[0479] When the pre - folding pipe column is at - 4° - 0°, when the seat reaches the rear 1% position → the handwheel 22 unfolds from 85° to 70° → the pipe column rises from (-113 mm, - 4°) to (-22.5 mm, - 4°), and at the same time the handwheel 22 unfolds from 70° (after unfolding, the seat synchronously returns to the default position) → the pipe column first turns upward to (-22.5 mm, y°) → the pipe column continues to move backward to (x, y°).

[0480] Folding signal → the handwheel 22 returns to the upright position → the handwheel 22 is actively locked at the 0 position.

[0481] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
