[0083] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0084] In this disclosure, unless otherwise stated, directional terms such as "up," "down," "front," "rear," "left," and "right" are generally defined according to the vehicle's operating state, and "inner" and "outer" refer to the inner and outer parts of the relevant components. Furthermore, terms such as "first" and "second" are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0085] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0086] like Figures 1-9 As shown, one aspect of this disclosure provides a steering device for a vehicle, including a steering wheel 2.

[0087] The steering device includes a first state and a second state. In the first state, the steering wheel 2 is located behind the dashboard 8. In the second state, at least a portion of the steering wheel 2 is located below the dashboard 8.

[0088] The first state can be understood as the unfolded state of steering wheel 2. In the first state, the driver can drive the vehicle normally using steering wheel 2. At this time, steering wheel 2 is behind the dashboard 8, and the driver can hold steering wheel 2 to perform steering operations while seated in the driver's cabin. The second state can be understood as the folded state of steering wheel 2. Under normal circumstances, steering wheel 2 can be folded when it is not needed. This reduces the space occupied by steering wheel 2 in the driver's seat, allowing for more space for the driver and a better riding experience. For example, steering wheel 2 can be folded, but not limited to, when the vehicle is parked, or when the vehicle is in intelligent driving or autonomous driving mode.

[0089] In the above technical solution, the steering wheel 2 can be folded under the dashboard, reducing the space occupied by the driver's seat and providing more space and comfort for the driver. By placing the steering wheel 2 under the dashboard 8 when not in use, there is no need to redesign the storage space of the dashboard 8. It can be directly applied to the dashboard 8 of existing models, without increasing costs or development cycles, thus ensuring efficiency. Furthermore, the design of the dashboard 8 and steering wheel 2 can be adapted to different vehicle models without special development, allowing for rapid and widespread application across various vehicle types. When the steering wheel 2 is not in use, it can be placed under the dashboard 8.

[0090] Optionally, in an emergency, the driver can grip the steering wheel 2 to perform emergency steering maneuvers, improving safety.

[0091] Optionally, in one embodiment of this disclosure, the steering wheel 2 is configured to rotate about a first rotation axis that extends along the width direction of the vehicle. This facilitates retracting the steering wheel 2 at least partially below the dashboard 8.

[0092] The steering wheel 2 is rotatable and can be at least partially retracted below the dashboard 8 to free up space in the driver's cabin. This increases the space utilization of the driver's cabin when the vehicle is in autonomous driving mode or when the driver is getting in or out of the vehicle, thereby improving the driver's comfort.

[0093] The first rotation axis extends along the width of the vehicle, allowing the steering wheel 2 to fold around this axis for easy storage. The steering wheel 2 itself rotates around the second rotation axis, enabling vehicle steering.

[0094] Alternatively, in another embodiment of this disclosure, the steering wheel 2 is configured to translate in the fore-and-aft direction to at least partially retract the steering wheel 2 below the dashboard 8. It is understood that the steering wheel 2 is not folded, but rather moved directly, and after the movement, it can be at least partially retracted below the dashboard 8, thus freeing up space in the driver's compartment.

[0095] Optionally, in one embodiment of this disclosure, in the first state, the steering wheel 2 is in an unfolded state, and in the second state, the steering wheel 2 is in a folded state.

[0096] It is understandable that the unfolded state of steering wheel 2 is a state in which the driver can hold steering wheel 2 to perform steering operations, and steering wheel 2 is roughly set up vertically. The folded state of steering wheel 2 allows steering wheel 2 to be rotated and tilted in a certain direction to achieve rotation and folding, so that steering wheel 2 can be set up roughly horizontally.

[0097] In the first state, the steering wheel 2 is in a position where normal driving requires operation, and the driver can hold the steering wheel 2 to perform steering operations while seated in the driver's cabin. In the second state, under normal circumstances, the steering wheel 2 does not require driver operation. At this time, the steering wheel 2 is located below the dashboard 8, which reduces the space occupied in the driver's cabin and also avoids excessive encroachment on the driver's legroom, ensuring sufficient legroom for the driver.

[0098] Alternatively, in another embodiment of this disclosure, the steering wheel 2 can be in an unfolded state in both the first and second states. That is, in the unfolded state, the steering wheel 2 is positioned approximately vertically and is not folded.

[0099] Alternatively, in one embodiment of this disclosure, in the second state, the steering wheel 2 is fully retracted below the dashboard 8.

[0100] In this context, the steering wheel 2 being completely retracted below the dashboard 8 can mean that, in the second state, the projection of the steering wheel 2 along the vehicle's height is set as the first projection area, and the projection of the dashboard 8 along the vehicle's height is set as the second projection area. The first projection area falls entirely within the second projection area, allowing the steering wheel 2 to be completely retracted below the dashboard 8. This arrangement further improves the space utilization of the driver's cabin and enhances comfort. It's understood that when the steering wheel 2 is completely retracted below the dashboard 8, from a top-down view, the dashboard 8 completely obscures the steering wheel 2. However, in other examples, the steering wheel 2 being completely retracted below the dashboard 8 can mean that the entire steering wheel 2 is positioned below the dashboard 8 in the height direction and is partially obscured by the dashboard 8.

[0101] Optionally, in one embodiment of this disclosure, the steering wheel 2 includes a frame 21 and a handwheel 22, with the handwheel 22 connected to the frame 21. In a second state, both the frame 21 and the handwheel 22 are located below the dashboard 8. The handwheel 22 is used by the driver to grip it, and the frame 21 provides support for the handwheel 22. By retracting both the frame 21 and the handwheel 22 below the dashboard 8, the space utilization of the driver's cabin can be further improved.

[0102] In some examples, the frame 21 and the handwheel 22 can rotate together around the first rotation axis to achieve the overall folding movement. In other examples, the frame 21 can remain stationary while the handwheel 22 is rotated around the first rotation axis to achieve the folding movement.

[0103] Alternatively, in another embodiment of this disclosure, in the second state, the steering wheel 2 can be partially retracted below the dashboard 8. That is, when viewed from above, a portion of the steering wheel 2 can be obscured by the dashboard 8, while another portion is not obscured by the dashboard 8.

[0104] In the second state, a portion of the steering wheel 2 is retracted below the dashboard 8. This can be achieved by a portion of the frame 21 being located below the dashboard 8, a portion of the handwheel 22 being located below the dashboard 8, or the frame 21 not being retracted below the dashboard 8, but the entire handwheel 22 of the steering wheel 2 being retracted below the dashboard 8. This can be configured as needed.

[0105] Optionally, in one embodiment of this disclosure, the steering device further includes a shielding mechanism, which includes a shielding member 31. The shielding member 31 is configured to form an accommodating space with the lower surface of the instrument panel 8. The accommodating space is used to accommodate the steering wheel 2 in a second state. The shielding member 31 can shield the steering wheel 2, ensuring the consistency and aesthetics of the instrument panel 8. It is understood that when the steering wheel 2 is retracted below the instrument panel 8, it can be placed within the accommodating space, at which point the shielding member 31 can shield the steering wheel 2.

[0106] Optionally, in one embodiment of this disclosure, the steering device further includes a connecting device 1 connected to the vehicle body, a steering wheel 2 connected to the connecting device 1, and the steering wheel 2 configured to be movable along the length direction of the connecting device 1 and / or along the vertical direction.

[0107] The connecting device 1 supports the steering wheel 2, so that in the first state, the steering wheel 2 is located behind the dashboard 8, allowing the driver to grip the steering wheel and perform steering operations. Furthermore, the position of the steering wheel 2 can be adjusted by adjusting the position of the connecting device 1 to accommodate drivers of different body types.

[0108] The steering wheel 2 can move along the length of the connecting device 1, allowing it to move back and forth and thus change its position. In some examples, the steering wheel 2 can move while the connecting device 1 remains stationary; in other examples, the steering wheel 2 and the connecting device 1 can move together. It should be noted that the steering wheel 2 is a drive-by-wire steering wheel, using electrical signals to steer the wheels. The connecting device 1 does not perform the transmission function for wheel steering; rather, it supports the steering wheel 2.

[0109] In the above embodiment, the first rotation axis of the steering wheel 2 is set at an angle to the axis of the connecting device 1, thereby allowing the steering wheel 2 to rotate toward the side of the connecting device 1, realizing the rotation and folding of the steering wheel 2.

[0110] Optionally, in one embodiment of this disclosure, the steering device further includes a closure 31. The steering wheel 2 is connected to the connecting device 1, and a through opening 81 is provided on the dashboard 8 for the connecting device 1 to pass through. The closure 31 is movably disposed at the through opening 81. In a first state, the closure 31 at least partially opens the through opening 81, and in a second state, the closure 31 closes the through opening 81.

[0111] The through-hole 81 allows part of the connecting device 1 to be inside the dashboard 8, while another part connects to the steering wheel 2 via the through-hole 81. In the first state, the steering wheel 2 is behind the dashboard 8. The movable arrangement of the closure 31 ensures that in the first state, when the steering wheel 2 needs to be behind the dashboard 8, the through-hole 81 is at least partially open, allowing the connecting device 1 to pass through, thus ensuring the steering wheel 2 is behind the dashboard 8. In the second state, when the steering wheel 2 is retracted below the dashboard 8, the connecting device 1 is not inserted through the through-hole 81. The closure 31 closes the through-hole 81, preventing the internal structure of the dashboard 8 from being exposed and affecting aesthetics. In some examples, the through-hole 81 extends through the dashboard 8 in a front-to-back direction.

[0112] In some examples, the closure 31 is movably connected to the dashboard and positioned at the through-hole 81 to close the through-hole 81. In other examples, the closure 31 may also be connected to other structures and positioned at the through-hole 81 to close the through-hole 81.

[0113] Optionally, in one embodiment of this disclosure, the instrument panel 8 is provided with a connecting through hole 82, which includes a first part 821 and a second part 822. The first part 821 is formed as a through opening 81. In a first state, the connecting device 1 passes through the first part 821, and in a second state, the connecting device 1 passes through the second part 822.

[0114] Both the first part 821 and the second part 822 can be through which the connecting device 1 passes. Depending on the position of the connecting device 1, it can be through either the first part 821 or the second part 822 to meet different needs. It is understood that the first part 821 and the second part 822 are interconnected, and the connecting device 1 can switch between the two. In the first state, the connecting device 1 passes through the first part 821, so that the steering wheel 2 is located behind the dashboard 8. In the second state, the connecting device 1 passes through the second part 822, so that the steering wheel 2 is located below the dashboard 8. In the second state, after the connecting device 1 passes through the second part 822, the first part 821 is exposed and can be closed by the sealing member 31. In some examples, the first part 821 is located above the second part 822, and the connecting device 1 can move up and down, allowing it to switch between the first part 821 and the second part 822.

[0115] Optionally, in one embodiment of this disclosure, the second portion 822 is located on the lower surface of the dashboard 8, and the first portion 821 is at least partially located on the side of the dashboard 8 facing the driver's seat of the vehicle. This arrangement allows the connecting device 1 to pass through the second portion 822 when the steering wheel 2 is located below the dashboard 8, and to pass through the first portion 821 when the steering wheel 2 is located behind the dashboard 8.

[0116] Optionally, in one embodiment of this disclosure, the steering device further includes a driver 32, the driving end of which is connected to the closure 31 to drive the closure 31 to move.

[0117] The actuator 32 can move the closure member 31, enabling it to actively close the through opening 81 without requiring manual operation, thus improving convenience. Furthermore, the actuator 32 can be linked to the movement of the steering wheel 2, so that when the steering wheel 2 is retracted below the dashboard 8, the actuator 32 drives the closure member 31 to close the through opening 81. Alternatively, in other embodiments, the closure member 31 can be manually moved to close the opening.

[0118] Optionally, in one embodiment of this disclosure, the driver 32 is configured to move the closure 31 toward or away from the through opening 81, and to avoid the connecting device 1 during the movement.

[0119] The closure 31, driven by the actuator 32, can move closer to or further away from the through-port 81. It is understood that when the through-port 81 needs to be closed, the closure 31 moves closer to the through-port 81 under the drive of the actuator 32; when the through-port 81 needs to be at least partially opened, the closure 31 moves further away from the through-port 81 under the drive of the actuator 32. In some examples, the closure 31 is designed as a separate unit from the dashboard 8, thus allowing the closure 31 to move relative to the dashboard 8, enabling connection or separation from the dashboard 8. When the closure 31 is connected to the dashboard 8, it closes the through-port 81; when separated from the dashboard 8, it at least partially opens the through-port 81.

[0120] During movement, the closure 31 can avoid the connecting device 1, thus preventing interference between the connecting device 1 and the closure 31 and affecting the sealing effect of the closure 31 on the through opening 81.

[0121] Alternatively, in another embodiment of this disclosure, the closure 31 may be hinged to the dashboard 8, and the driver 32 may drive the closure 31 to rotate, thereby closing the through opening 81 or at least partially opening the through opening 81.

[0122] Optionally, in one embodiment of this disclosure, the actuator 32 includes a telescopic rod, one end of which is hinged to the closure member 31, and the other end of which is hinged to the frame of the instrument panel 8. The telescopic rod's extension and retraction can drive the actuator 32. The hinge between the telescopic rod and the closure member 31 ensures that the closure member 31 is directly opposite the through-hole 81 when it approaches or moves away from it, guaranteeing a sealing effect and preventing misalignment, thus ensuring the movement of the closure member 31. In some examples, the telescopic rod can be an electric actuator, which extends or retracts by electrical power.

[0123] Alternatively, in another embodiment of this disclosure, the driver 32 includes a motor and a transmission component. The output end of the motor is connected to the transmission component, and the transmission component is connected to the enclosure 31. The motor drives the enclosure 31 to move.

[0124] Optionally, in one embodiment of this disclosure, the steering device further includes a guide member 33, one end of which is connected to the closure member 31, and the other end of which is used to connect to the frame of the instrument panel 8, so that the closure member 31 moves along a preset direction of the guide member 33.

[0125] The guide member 33 guides the movement of the closing member 31, ensuring that the closing member 31 moves in the preset direction of the guide member 33. This guarantees the stability of the closing member 31's movement and ensures alignment with the through opening 81, thus achieving the closure of the through opening 81. The guide member 33 is supported by the frame of the instrument panel 8, ensuring stability and providing stable guidance during the movement of the closing member 31.

[0126] Optionally, in one embodiment of this disclosure, the guide member 33 includes a guide rail 331 and a connecting rod 332. The guide rail 331 is connected to the frame of the instrument panel 8 and 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 closure member 31.

[0127] In this design, the track 333 on the guide rail 331 provides guidance, while the connecting rod 332 connects to the closing member 31, allowing the closing member 31 to move along the extension direction of the track 333 on the guide rail 331, thus achieving the guiding function. One end of the connecting rod 332 can move along the extension direction of the track 333, generating a linkage that drives the movement of the closing member 31. The hinged connection between the connecting rod 332 and the track 333, and also between the connecting rod 332 and the closing member 31, ensures that the closing member 31 is directly opposite the through opening 81 during movement, facilitating the closure of the through opening 81. It can be understood that when the closing member 31 moves along the extension direction of the track 333, the connecting rod 332 can rotate relative to the track 333 and the closing member 31, ensuring that the closing member 31 is directly opposite the through opening 81. In some examples, one end of the link 332 is provided with a pulley, which is slidably connected to the track 333. One end of the link 332 is rotatably connected to the axis of the pulley, and the other end of the link 332 is hinged to the closure 31 by a pin.

[0128] Optionally, in one embodiment of this disclosure, the connecting rod 332 includes a first rod 3321 and a second rod 3322. The first rod 3321 and the second rod 3322 are hinged to each other. The first rod 3321 is slidably hinged to the track 333, and the end of the second rod 3322 away from the first rod 3321 is hinged to the closing member 31. By configuring the first rod 3321 and the second rod 3322, the closing member 31 can move in multiple directions, which helps to avoid interference with the connecting device 1. It is understood that the interconnection of the first rod 3321 and the second rod 3322 allows them to rotate relative to each other. Therefore, when the closing member 31 changes its direction of movement, there is no problem of restricted movement, which facilitates adjustment of the position of the closing member 31.

[0129] The track 333 includes a first section and a second section, which are interconnected. The first section extends in the front-back direction and the second section extends in the left-right direction. This allows the closure 31 to move in the front-back direction and in the left-right direction, which helps to avoid the connecting device 1.

[0130] Optionally, in one embodiment of this disclosure, two guide rails 331 are provided, and the two ends of the first rod 3321 are slidably hinged to the tracks 333 of the two guide rails 331 respectively. By providing two guide rails 331, dual guidance can be achieved, ensuring guiding stability and the movement stability of the closure 31. The two guide rails 331 can be arranged in parallel, the tracks 333 of the two guide rails 331 can be arranged in parallel, and the extension directions of the two tracks 333 are consistent.

[0131] Optionally, in one embodiment of this disclosure, two second rods 3322 are provided. One end of each of the two second rods 3322 is hinged to the first rod 3321, and the other end of each of the two second rods 3322 is hinged to the closing member 31. The lengths of the two second rods 3322 are set differently. By providing two second rods 3322, two limiting effects are generated, which can restrict the degree of freedom of the closing member 31, thereby helping the closing member 31 to maintain a positive alignment with the through opening 81 and ensuring the closing effect of the closing member 31 on the through opening 81.

[0132] Among them, the connection positions of one end of the two second rods 3322 and the first rod 3321 do not coincide, and the connection positions of the other ends of the two second rods 3322 and the closure member 31 do not coincide. The connection positions of the other ends of the two second rods 3322 and the closure member 31 can be set at intervals in the left and right directions, which helps the closure member 31 to remain directly opposite the through opening 81 and improve the sealing effect.

[0133] The first rod 3321 can be inclined to accommodate the different lengths of the two second rods 3322, thereby enabling the two second rods 3322, the closure member 31 and the first rod 3321 to form an irregular polygonal structure, which can improve the stability of the movement of the two second rods 3322, the closure member 31 and the first rod 3321.

[0134] Optionally, in another embodiment of this disclosure, the guide member 33 includes a guide plate with a guide groove. The closing member 31 is slidably connected within the guide groove, and the movement of the closing member 31 is guided by the guide groove, causing the closing member 31 to move along the extension direction of the guide groove. The guide groove may be positioned obliquely rearward, allowing the closing member 31 to move in an obliquely rearward direction and approach the through opening 81, thereby closing the through opening 81.

[0135] Optionally, in one embodiment of this disclosure, the connecting device 1 includes a tubular column. In other examples, the connecting device 1 may also be other support structures.

[0136] Alternatively, in one embodiment of this disclosure, the connecting device 1 is connected to the vehicle body via the frame of the dashboard 8. In other examples, the connecting device 1 may be directly connected to the vehicle body.

[0137] Optionally, in one embodiment of this disclosure, the steering device further includes a movable mechanism 4, and the steering wheel 2 is rotatably connected to the connecting device of the steering device through the movable mechanism 4. The steering wheel 2 can rotate along a first rotation axis through the movable mechanism 4; or the steering wheel 2 can rotate along the first rotation axis and along a second rotation axis through the movable mechanism 4.

[0138] The first rotation axis is along the width of the vehicle; the second rotation axis is the rotation center line of the steering wheel 2. The connecting device is directly or indirectly connected to the vehicle body.

[0139] The steering wheel 2 is connected to the first rotating shaft 41, so that rotation of the first rotating shaft 41 can drive the steering wheel 2 to rotate around the first rotation axis, allowing the steering wheel 2 to rotate relative to the connecting device and fold to one side of the connecting device. It is understood that the first rotating shaft 41 is not for the purpose of steering the wheels, but rather for folding the steering wheel 2 so that it can be stored under the dashboard 8. Rotation of the steering wheel 2 around the second rotation axis enables the steering of the wheels.

[0140] Optionally, in the second state, the steering wheel 2 can rotate around a second rotation axis. That is, even when the steering wheel 2 is folded under the dashboard 8, it can still be rotated around the second rotation axis to steer the wheels. This allows the driver to quickly grasp the steering wheel 2 in an emergency for emergency steering maneuvers, improving safety.

[0141] Optionally, in one embodiment of this disclosure, the movable mechanism includes a first movable body 44 and a first rotating shaft 41 arranged along a first rotation axis. The first movable body 44 is connected to the steering wheel 2, and the first rotating shaft 41 is directly or indirectly connected to a connecting device. The first movable body 44 rotates around the first rotation axis via the first rotating shaft 41 to drive the steering wheel to rotate around the first rotation axis.

[0142] When the first rotating shaft 41 rotates, it drives the first movable body 44 and the steering wheel 2 to rotate together around the first rotation axis, achieving rotational folding. This maintains the connection between the steering wheel 2 and the first movable body 44, allowing the steering wheel 2 to rotate around the second rotation axis in the second state. In some examples, the first movable body 44 may include two interconnected connecting arms, each connected to one end of the first rotating shaft 41, with the steering wheel 2 connected to both arms. The first movable body 44 may be an electric drive unit for the steering wheel, enabling signal acquisition and thus steer-by-wire.

[0143] Optionally, in one embodiment of this disclosure, the movable mechanism further includes a drive member 42, and the first rotating shaft 41 is connected to the connecting device via the drive member 42. The drive member 42 drives the first rotating shaft 41 to rotate.

[0144] Optionally, in one embodiment of this disclosure, the steering wheel 2 is rotatable along a first rotation axis and a second rotation axis via a movable mechanism 4. The movable mechanism 4 further includes a second rotating shaft 45 disposed along the second rotation axis. The steering wheel 2 is connected to the first movable body 44 via the second rotating shaft 45, so that the steering wheel 2 can rotate around the second rotation axis. By rotating the steering wheel 2 around the second rotation axis, the steering of the vehicle's wheels can be controlled.

[0145] Optionally, in one embodiment of this disclosure, the steering wheel 2 can switch between a first state and a second state via a movable mechanism 4. The movable mechanism 4 is connected to the steering wheel 2, and the steering wheel 2 can move via the movable mechanism 4, allowing its position to change and retract below the dashboard 8. The movable mechanism 4 may not be connected to the connecting device 1; instead, it may be connected to the frame of the dashboard 8, while the steering wheel 2 is directly connected to the connecting device 1.

[0146] Alternatively, in another embodiment of this disclosure, the connecting device includes a connecting device 1, and the steering wheel 2 can switch between a first state and a second state via the movable mechanism 4 and the connecting device 1.

[0147] The connecting device 1 and the steering wheel 2 can be connected by the movable mechanism 4, which can support the steering wheel 2. The movable mechanism 4 can be between the connecting device 1 and the steering wheel 2, and can make the steering wheel 2 move, change the position of the steering wheel 2, and store the steering wheel 2.

[0148] In some examples, the actuating mechanism 4 allows the steering wheel 2 to rotate relative to the connecting device 1 about a first rotation axis, enabling the steering wheel 2 to fold to one side of the connecting device 1. In other examples, the actuating mechanism 4 allows the steering wheel 2 to retract horizontally, allowing it to be directly stored under the dashboard 8.

[0149] Optionally, in one embodiment of this disclosure, the movable mechanism 4 includes a first rotating shaft 41, the steering wheel 2 is connected to the first rotating shaft 41, the first rotating shaft 41 extends along the direction of a first rotation axis, and the first rotation axis extends along the width direction of the vehicle.

[0150] Optionally, in one embodiment of this disclosure, the active mechanism 4 further includes a driving member 42, which is connected to the first rotating shaft 41 and is used to drive the first rotating shaft 41 to rotate around the first rotation axis.

[0151] The drive component 42 drives the first rotating shaft 41 to rotate around the first rotation axis, thereby rotating the steering wheel 2 and achieving active control without manual operation, improving convenience and comfort. In some examples, both ends of the first rotating shaft 41 are connected to the steering wheel 2, and the drive component 42 is connected to the middle of the first rotating shaft 41, driving the first rotating shaft 41 to rotate, ensuring the smooth rotation of the steering wheel 2. Of course, in other examples, the drive component 42 may not be provided, and the steering wheel 2 may be rotated around the first rotation axis by manual operation, or the steering wheel 2 may be folded.

[0152] Optionally, in one embodiment of this disclosure, the driving component 42 includes a folding motor 421 and a folding transmission 422, the output end of the folding motor 421 is connected to the folding transmission 422, and the folding transmission 422 is connected to the first rotating shaft 41.

[0153] The folding motor 421 generates rotational force, which is transmitted to the first rotating shaft 41 through the folding transmission 422, causing the first rotating shaft 41 to rotate, thereby driving the steering wheel 2 to rotate around the first rotation axis and achieve folding.

[0154] Alternatively, in another embodiment of this disclosure, the drive unit 42 includes an electric push rod, one end of which is hinged to the steering wheel 2. The electric push rod can extend or retract, thereby driving the steering wheel 2 to rotate.

[0155] Optionally, in one embodiment of this disclosure, the folding transmission 422 includes a first worm gear 4221 and a first worm 4222. One end of the first worm 4222 is connected to the output end of the folding motor 421. The first worm gear 4221 meshes with the first worm 4222. The first worm gear 4221 is fixedly sleeved on the first rotating shaft 41.

[0156] In this configuration, the folding motor 421 drives the first worm gear 4222 to rotate. The first worm wheel 4221 meshes with the first worm gear 4222, causing the rotation direction of the first worm gear 4222 to switch to the rotation direction of the axis of the first worm wheel 4221. Then, the first worm wheel 4221 drives the first rotating shaft 41 to rotate coaxially, thereby causing the steering wheel 2 to rotate around the first rotation axis. Through the cooperation of the first worm wheel 4221 and the first worm gear 4222, the folding motor 421 can be located on one side of the first rotating shaft 41, which can reduce the space occupied in the axial direction of the first rotating shaft 41 and facilitate its arrangement.

[0157] Alternatively, in another embodiment of this disclosure, the folding transmission 422 includes a reducer, the motor is connected to the input end of the reducer, and the first rotating shaft 41 is connected to the output end of the reducer. The reducer may include a large gear 621 and a small gear 621, wherein one of the large gear 621 or the small gear 621 is fixedly sleeved on the first rotating shaft 41.

[0158] Optionally, in one embodiment of this disclosure, the connecting device 1 further includes a connector 43, through which the first rotating shaft 41 passes and is connected to the steering wheel 2. In some examples, the connector 43 may be a housing, with the first rotating shaft 41 disposed within the housing, and both ends of the first rotating shaft 41 rotatably extending out of the connector 43. The connector 43 can cover the first rotating shaft 41, preventing exposure of the first rotating shaft 41 and related structures, thus avoiding aesthetic impact. Simultaneously, the connector 43 can protect the first rotating shaft 41, preventing damage. Furthermore, a portion of the drive component 42 in the above embodiment can also be disposed within the connector 43, and covered and protected by the connector 43.

[0159] In some examples, one end of the connector 43 can be configured as an open end, which is connected to the connecting device 1. The connecting device 1 can partially extend into the connector 43 and connect to it. The steering wheel 2 is connected to the end of the connector 43 away from the connecting device 1.

[0160] Optionally, in one embodiment of this disclosure, the outer surface of the connector 43 is provided with a clearance groove 431. The first rotating shaft 41 passes through the groove wall of the clearance groove 431 and exits the connector 43. The first movable body 44 of the movable mechanism 4 is partially disposed in the clearance groove 431. The clearance groove 431 reduces interference between the movable mechanism 4 and the connector 43 when rotating around the first rotation axis, thereby facilitating the rotation of the steering wheel 2 around the first rotation axis and realizing the rotational folding of the steering wheel 2. In some examples, clearance grooves 431 are provided on both sides of the end of the connector 43 away from the connecting device 1. The first rotating shaft 41 is partially inside the clearance groove 431. The movable mechanism 4 includes two connecting arms that extend into the clearance groove 431 and are connected to the first rotating shaft 41. The connecting arms can rotate within the clearance groove 431, realizing the rotation of the steering wheel 2 around the first rotation axis.

[0161] By connecting the steering wheel 2 to the connecting device 1, the steering wheel 2 can move along the length direction and / or along the vertical direction when the connecting device 1 moves, thereby changing the position of the steering wheel 2. The steering wheel 2 can be moved to the bottom of the dashboard 8, and a small range of position adjustment of the steering wheel 2 can also be achieved to accommodate drivers of different body types.

[0162] When the connecting device 1 moves along its length, the steering wheel 2 can also move along the length of the connecting device 1, enabling the steering wheel 2 to move back and forth and to be completely retracted under the dashboard 8. When the connecting device 1 moves up and down, the steering wheel 2 can also move up and down, enabling the steering wheel 2 to move up and down, thus avoiding interference with the dashboard 8 when the steering wheel 2 rotates around the first rotation axis or moves back and forth.

[0163] Optionally, in one embodiment of this disclosure, the steering device further includes a telescopic mechanism 5, which is connected to the connecting device 1 and used to drive the connecting device 1 to move along its length. The telescopic mechanism 5 enables the connecting device 1 to move along its length. One end of the connecting device 1 is connected to one end of the telescopic mechanism 5. It is understood that the telescopic mechanism 5 can extend or retract, and when the telescopic mechanism 5 extends or retracts, it drives the connecting device 1 to move along its length.

[0164] Optionally, in one embodiment of this disclosure, the telescopic mechanism 5 includes a telescopic motor 51 and a telescopic transmission component 52, the telescopic transmission component 52 being connected to the output end of the telescopic motor 51 and the connecting device 1 respectively. The telescopic motor 51 generates rotational force, which drives the connecting device 1 to move via the telescopic transmission component 52, causing the connecting device 1 to move along its length, thereby enabling the steering wheel 2 to move back and forth.

[0165] Optionally, the telescopic transmission component 52 includes a connector and a second worm gear. One end of the second worm gear is connected to the output end of the telescopic motor 51. The connector is provided with teeth, and the other end of the second worm gear meshes with the connector.

[0166] The teeth on the connector mesh with the second worm gear, which rotates under the drive of the telescopic motor 51. This causes the connector to move relative to the second worm gear along its axial direction. The connector is connected to the connecting device 1, and the axis of the connecting device 1 is parallel to the axis of the connector. This causes the connecting device 1 to move along its length, thereby enabling the steering wheel 2 to move back and forth.

[0167] Alternatively, in another embodiment of this disclosure, the telescopic transmission component 52 may be a lead screw and nut pair, with the motor connected to the lead screw of the lead screw and nut pair, driving the lead screw to rotate, and the sliding block on the lead screw and nut pair connected to the connecting device 1, driving the connecting device 1 to move.

[0168] Alternatively, in another embodiment of this disclosure, the telescopic mechanism 5 may also be a cylinder, which is capable of extending or shortening. The output end of the cylinder is connected to the connecting device 1, and the axis of the cylinder is parallel to the axis of the connecting device 1, thereby driving the connecting device 1 to move along its length.

[0169] Optionally, in one embodiment of this disclosure, the steering device further includes a lifting drive mechanism 6, which is connected to the connecting device 1 and used to drive the connecting device 1 to move in the vertical direction. The lifting drive mechanism 6 enables the connecting device 1 to move in the vertical direction, thereby driving the steering wheel 2 to move in the vertical direction.

[0170] Optionally, in one embodiment of this disclosure, the lifting drive mechanism 6 includes a lifting motor 61 and a lifting transmission component 62, the lifting transmission component 62 being connected to the output end of the lifting motor 61 and the connecting device 1 respectively. The lifting motor 61 generates rotational force, which drives the connecting device 1 to move vertically via the lifting transmission component 62, thereby driving the steering wheel 2 to move vertically.

[0171] Optionally, in one embodiment of this disclosure, the lifting transmission component 62 includes a gear 621 and a rack 622. The gear 621 is connected to the output end of the lifting motor 61, the rack 622 meshes with the gear 621, and the rack 622 is connected to the connecting device 1.

[0172] The lifting motor 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 extension direction of the rack 622, converting the rotational force into linear motion. The rack 622 is connected to the connecting device 1, thereby realizing the movement of the connecting device 1. The rack 622 extends in the vertical direction, thereby driving the connecting device 1 to move in the vertical direction, which in turn drives the steering wheel 2 to move in the vertical direction.

[0173] Alternatively, in another embodiment of this disclosure, the lifting drive mechanism 6 includes an electric push rod, which is arranged in the vertical direction and can extend or shorten in the vertical direction. The connecting device 1 is connected to the electric push rod, so that the electric push rod drives the connecting device 1 to move up and down.

[0174] Optionally, in one embodiment of this disclosure, the steering device further includes a lifting guide mechanism 7 and a mounting bracket 9. The lifting guide mechanism 7 is connected to both the connecting device 1 and the mounting bracket 9. The lifting guide mechanism 7 guides the vertical movement of the connecting device 1, ensuring the stability of its vertical movement. It is understood that the lifting guide mechanism 7 extends vertically, and the mounting bracket 9 provides support for the lifting guide mechanism 7. The mounting bracket 9 can be installed on the frame of the instrument panel 8.

[0175] Optionally, in one embodiment of this disclosure, the lifting guide mechanism 7 includes a slide rail 71 and a sliding part 72. The sliding part 72 is slidably connected to the slide rail 71. One of the slide rail 71 and the sliding part 72 is connected to the mounting bracket 9, and the other is connected to the connecting device 1.

[0176] The slide rail 71 guides the sliding part 72. The slide rail 71 is arranged vertically, and the sliding part 72 can slide up and down on the slide rail 71. By connecting to the mounting frame 9 and the connecting device 1 respectively, the mounting frame 9 and the connecting device 1 can slide relative to each other. The limiting effect of the slide rail 71, and the resulting guiding and limiting effect, restricts the movement of the connecting device 1 in the vertical direction, ensuring movement stability. In some examples, the slide rail 71 is connected to the mounting frame 9, and the sliding part 72 is connected to the connecting device 1.

[0177] Alternatively, in another embodiment of this disclosure, the lifting guide mechanism 7 includes a slide groove and a slider, the slider being slidably connected in the slide groove, the slide groove extending in the vertical direction, the slider being disposed on the outer side wall of the connecting device 1, and the slide groove being disposed on the mounting bracket 9.

[0178] Optionally, in one embodiment of this disclosure, the bottom of the dashboard 8 is provided with an upwardly recessed portion, and in the second state, at least a portion of the steering wheel 2 is located in the recessed portion. The recessed portion accommodates the steering wheel 2, allowing it to be positioned as close as possible to the dashboard 8, thus avoiding excessive occupation of legroom in the driver's compartment and ensuring driver comfort. It is understood that in some examples, after the steering wheel 2 is rotated and folded, the connecting device 1 moves the steering wheel 2 to below the dashboard 8. At this time, the connecting device 1 can move upwards, causing the steering wheel 2 to move upwards and be accommodated in the recessed portion.

[0179] Alternatively, in another embodiment of this disclosure, the dashboard 8 has a downwardly extending portion on the side facing the driver's seat of the vehicle. In the second state, the extension portion is used to cover at least part of the steering wheel 2. By providing the extension portion, the steering wheel 2 can be covered after it is retracted below the dashboard 8, thus hiding the steering wheel 2 and improving aesthetics.

[0180] Optionally, in another embodiment of this disclosure, the bottom of the dashboard 8 is provided with an upwardly recessed portion. In a second state, at least a portion of the steering wheel 2 is located in the recessed portion, and a downwardly extending portion is formed on the side of the dashboard 8 facing the driver's seat of the vehicle. In the second state, the extending portion is used to cover at least a portion of the steering wheel 2. The recessed portion can accommodate the steering wheel 2, thereby allowing the steering wheel 2 to be as close to the dashboard 8 as possible, thus avoiding excessive occupation of the driver's legroom and ensuring driver comfort. It is understood that in some examples, after the steering wheel 2 is rotated and folded, the connecting device 1 moves the steering wheel 2 to below the dashboard 8. At this time, the connecting device 1 can move upward, moving the steering wheel 2 upward to be accommodated in the recessed portion. Then, the extending portion can cover the steering wheel 2, making the steering wheel 2 hidden, which can improve aesthetics.

[0181] Optionally, in one embodiment of this disclosure, during the transition from the first state to the second state, the movement state of the steering wheel 2 includes a rotational state in which the steering wheel 2 rotates about a first rotation axis, the first rotation axis extending along the width direction of the vehicle. By rotating the steering wheel 2 about the first rotation axis, the steering wheel 2 can be rotated and folded.

[0182] Optionally, in one embodiment of this disclosure, during the process of switching from the first state to the second state, the movement state of the steering wheel 2 further includes at least one of the following: a downward movement state in which the steering wheel 2 moves downward, a retraction state in which the steering wheel 2 moves forward, and an upward movement state in which the steering wheel 2 moves upward.

[0183] The downward movement of the steering wheel 2 allows it to move downwards, facilitating its rotation around the first axis of rotation and avoiding interference. It also facilitates its forward movement, further avoiding interference.

[0184] Among them, the forward-moving retracted state of the steering wheel 2 allows the steering wheel 2 to move forward and be brought as far as possible under the dashboard 8, and the steering wheel 2 can be completely brought under the dashboard 8.

[0185] The upward movement of steering wheel 2 allows it to rest comfortably under the dashboard 8 after retracting, reducing legroom requirements. It's understandable that the movement of steering wheel 2 during the transition from the second to the first state is the opposite of the movement during the transition from the first to the second state.

[0186] Optionally, in one embodiment of this disclosure, the steering wheel 2 sequentially passes through a rotating state and a retracted state to switch from a first state to a second state. It can be understood that the steering wheel 2 can switch from the first state to the second state by rotating around a first rotation axis and moving forward, that is, by retracting the steering wheel 2 below the dashboard 8.

[0187] Optionally, in one embodiment of this disclosure, the steering wheel 2 sequentially passes through a lowered state, a rotated state, a retracted state, and an raised state to switch from the first state to the second state. It can be understood that the movement of the steering wheel 2 involves it first lowering, then rotating around a first rotation axis, then moving forward, and finally moving upward to rest against the underside of the dashboard 8, thus switching from the first state to the second state, i.e., retracting the steering wheel 2 to the underside of the dashboard 8.

[0188] Optionally, in one embodiment of this disclosure, the steering wheel 2 sequentially passes through a rotating state, a lowered state, a retracted state, and an raised state to switch from the first state to the second state. It can be understood that the movement of the steering wheel 2 involves it first rotating around a first rotation axis, then lowering, then moving forward, and finally moving upward to rest against the underside of the dashboard 8, thus switching from the first state to the second state, i.e., retracting the steering wheel 2 to the underside of the dashboard 8.

[0189] The steering wheel 2 is connected to the connecting device 1. The steering wheel 2 can rotate relative to the connecting device 1 around the first rotation axis. When the connecting device 1 moves, it can drive the steering wheel 2 to move synchronously, thereby changing the position of the steering wheel 2 and allowing the steering device to switch between the first state and the second state.

[0190] Optionally, in one embodiment of this disclosure, a through opening 81 is provided on the dashboard 8, and in a first state, the steering wheel 2 is located directly behind the through opening 81.

[0191] In the first state, the steering wheel 2 is located behind the dashboard 8. At this time, the steering wheel 2 can provide a certain degree of obstruction, which can block at least part of the through-hole 81.

[0192] The steering mechanism also includes a closure 31. In a first state, the closure 31 at least partially opens the through opening 81. In a second state, the closure 31 closes the through opening 81. In the second state, the steering wheel 2 is located below the dashboard 8, and the through opening 81 is open. Closing the through opening 81 by the closure 31 prevents the structure inside the dashboard 8 from being exposed through the through opening 81, thus improving aesthetics.

[0193] In some examples, in the first state, the closing member 31 is located in the first position. During the transition from the first state to the second state, the closing member 31 first moves left and right to the second position, and then moves from the second position to the third position to close the through opening 81. It can be understood that the closing member 31 involves two movements: first moving left and right, and then moving backward to the through opening 81 to close it. This arrangement avoids interference with the connecting device 1.
