Description

Technical Field

[0001] This invention relates to the field of vehicle manufacturing technology, and more particularly to a steering wheel and a vehicle having the steering wheel. Background Technology

[0002] With the development of intelligent vehicles, foldable steering wheels have become an important feature to enhance the driving experience, especially in autonomous driving mode and when passenger comfort is required, as they can free up more interior space.

[0003] In related technologies, the steering wheel is a rigid, integral structure that occupies a large space and cannot be flexibly deformed. Its folding and storage function is limited, and even after folding and storing, it still occupies the space in the cockpit and cannot free up more interior space. In other words, the existing steering wheel storage, which only has simple extension, folding, and flipping functions, is difficult to meet the needs of a smart cockpit. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a steering wheel that is small in size and occupies little space, can be precisely stored inside the dashboard and on both sides of the pillar, increases the free space in the cockpit, realizes the complete release of the interior space of the cockpit, supports zero-gravity seat reclining, and meets the needs of intelligent cockpit.

[0006] According to an embodiment of the present invention, the steering wheel has a main handwheel and side handwheels that can extend rearward, and the paired side handwheels can rotate and unfold relative to each other to perform an unfolding action. When the steering wheel is unfolded, the rearward-extending main handwheel and the unfolded side handwheels are joined to form a complete annular disc, realizing the unfolding of the steering wheel 100. The driver can stably hold the complete annular disc to drive the vehicle normally, ensuring driving safety. The paired side handwheels can rotate and retract relative to each other to perform a folding action, so that the steering wheel reaches a folded state. In the folded state, the folded side handwheels and the main handwheel can be simultaneously retracted forward to achieve the folding and storage of the steering wheel. Through the independent movement and mutual cooperation of the side handwheels and the main handwheel, the overall volume of the steering wheel can be greatly reduced after the steering wheel is folded and stored, reducing the space occupied by the steering wheel. This allows the steering wheel to be accurately stored in the dashboard and on both sides of the pillar, increasing the free space in the cockpit and realizing the complete release of the interior space of the cockpit. It supports zero-gravity seats to lie flat, meeting the needs of intelligent cockpits, and can integrate more functions to improve the user experience.

[0021] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to 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 invention based on the specific circumstances.

[0024] Unless otherwise specified, the front-back direction in this application refers to the longitudinal direction of the vehicle, i.e., the X direction; the left-right direction refers to the lateral direction of the vehicle, i.e., the Y direction; and the up-down direction refers to the vertical direction of the vehicle, i.e., the Z direction.

[0025] The following is for reference. Figures 1-25 The steering wheel 100 according to an embodiment of the present invention is small in size and occupies little space. It can be precisely stored in the instrument panel 200 and stored on both sides of the column, increasing the release space of the cockpit and realizing the complete release of the interior space of the cockpit. It supports zero-gravity seats to lie flat and meets the needs of intelligent cockpit.

[0026] like Figures 1-25 As shown, a steering wheel 100 according to an embodiment of the present invention includes: a main handwheel 1 and a side handwheel 2. The steering wheel 100 of this application may be a full-width steering wheel.

[0027] The main handwheels 1 are arranged opposite each other, meaning there can be two, four, or more main handwheels 1, with each pair of main handwheels 1 facing each other in a predetermined direction to maintain the overall symmetry and aesthetics of the steering wheel 100 and facilitate folding. The main handwheels 1 can extend and retract in the front-to-back direction, meaning they can move linearly in the front-to-back direction of the steering wheel 100. When the steering wheel 100 needs to be unfolded, each main handwheel 1 can extend backward in the front-to-back direction to reach the unfolded position; when the steering wheel 100 needs to be folded, each main handwheel 1 can retract forward in the front-to-back direction to reach the folded position.

[0028] The side handwheels 2 are arranged in pairs, that is, one, two or more pairs of side handwheels 2 can be set, and each pair of pairs is a pair of side handwheels 2; a pair of side handwheels 2 includes two side handwheels 2 that are movably connected. The two side handwheels 2 in the same pair can rotate and fold relative to each other, and each side handwheel 2 can move linearly in the front-back direction of the steering wheel 100; when the steering wheel 100 needs to be unfolded, the two side handwheels 2 in the same pair can rotate relative to each other in the rear and can extend backward in the front-back direction of the steering wheel 100 so that the side handwheels 2 can reach the unfolded position; when the side handwheels 2 need to be folded, the two side handwheels 2 in the same pair can rotate relative to each other in the front to reach the folded state b, and can retract forward in the front-back direction of the steering wheel 100 to the storage position.

[0029] Furthermore, the steering wheel 100 has an unfolded state a and a folded state b. When the steering wheel 100 is in unfolded state a, it is in the unfolded position. At this time, the driver can use the steering wheel 100 to drive the vehicle normally, or the vehicle can drive automatically. When the steering wheel 100 is in folded state b, the side handwheel 2 is folded and retracted. Then, the main handwheel 1 can further retract with the folded side handwheel 2 to bring the steering wheel 100 to the retracted state. At this time, the cockpit space can be freed up, improving the user experience. The vehicle can also be in automatic driving mode at this time.

[0030] When the steering wheel 100 is in the unfolded state a, the main handwheel 1, which extends backward to the unfolded position, and the side handwheel 2, which extends backward to the unfolded position, are joined to form a complete ring-shaped disc. That is, at the unfolded position, a complete ring-shaped disc is formed. At this time, the user can hold the complete ring-shaped disc to operate the steering and drive the vehicle. The disc structure is stable and reliable, and the driver can hold the complete ring-shaped disc stably to drive the vehicle normally, ensuring driving safety. The two side handwheels 2 of the same pair can rotate inward around the axis of rotation so that the two side handwheels 2 come closer to each other and fold together, so that the steering wheel 100 is in the folded state b. The folded side handwheels 2 can also retract forward synchronously with the main handwheel 1. That is, the folded side handwheels 2 can move forward synchronously with the main handwheel 1 so that the side handwheels 2 and the main handwheel 1 can perform the retraction action at the same time and reach the retracted position, achieving the retracted state.

[0031] Therefore, by independently and collaboratively moving the main handwheel 1 and the side handwheel 2, the steering wheel 100 can be folded and stored. When storing, since both the main handwheel 1 and the side handwheel 2 retract forward in the front-back direction, the size of the steering wheel 100 in the front-back direction can be reduced. Also, when folding, the pair of side handwheels 2 rotate forward to fold and gather, allowing the two side handwheels 2 of the same pair to overlap in the thickness direction, thereby reducing the size of the steering wheel 100 in the first direction. Thus, through the cooperation of the side handwheel 2 and the main handwheel 1, the overall volume of the steering wheel 100 can be greatly reduced after folding and storing, reducing the space occupied by the steering wheel 100. This allows it to be precisely stored inside the dashboard 200, increasing the free space in the cockpit and achieving complete release of the interior space of the cockpit. This supports zero-gravity seat reclining, meets the needs of a smart cockpit, and allows for the integration of more functions.

[0032] It is understandable that when the steering wheel 100 is folded and stored, the main handwheel 1 and the side handwheel 2 can also tilt forward and retract in the front-back direction. That is, when the two main handwheels 1 move forward, they can also move toward each other in the first direction, which can further reduce the size of the steering wheel 100 in the first direction. When the two side handwheels 22 in the same pair retract backward, they can also move toward each other in the second direction, which can further reduce the size of the steering wheel 100 in the second direction. This makes the overall volume of the steering wheel 100 smaller and the space occupied less after folding and storing. The first direction and the second direction can be the up-down direction and the left-right direction of the steering wheel 100.

[0033] It should also be noted that the relative main handwheel 1 and the paired side handwheels 2 can be driven by one set of drive mechanisms. This reduces the volume occupied by the drive mechanism and helps to reduce the overall size of the steering wheel 100. Alternatively, they can be driven by two sets of drive mechanisms respectively. That is, the first set of drive mechanisms drives the relative main handwheel 1 and the second set of drive mechanisms drives the paired side handwheels 2. This allows for independent driving of the main handwheel 1 and the side handwheels 2, improving the fault tolerance rate and thus improving the folding reliability of the steering wheel 100. It also reduces the number of transmission structures. Furthermore, each pair of paired side handwheels 2 can be driven by multiple sets of drive mechanisms, and the two relative main handwheels 1 can also be driven by two sets of drive mechanisms. This further improves the folding reliability of the steering wheel 100, reduces the number of transmission structures, and simplifies the design.

[0034] According to an embodiment of the present invention, the steering wheel 100 has a main handwheel 1 and side handwheels 2 that can extend rearward, and the paired side handwheels 2 can rotate relative to each other to unfold, reaching an unfolded state a. In unfolded state a, the rearward-extending main handwheel 1 and the unfolded side handwheels 2 are joined to form a complete annular disc, realizing the unfolding of the steering wheel 100. The driver can stably hold the complete annular disc to drive the vehicle normally, ensuring driving safety. The paired side handwheels 2 can rotate relative to each other to fold, so that the steering wheel 100 reaches a folded state b. In folded state b, the folded side handwheels... The side handwheel 2 and the main handwheel 1 retract forward synchronously to achieve the folding and storage of the steering wheel 100. Through the independent movement and mutual cooperation of the side handwheel 2 and the main handwheel 1, the overall volume of the steering wheel 100 can be greatly reduced after folding and storage, thus reducing the space occupied by the steering wheel 100. This allows the steering wheel 100 to be accurately stored inside the dashboard 200 and on both sides of the pillar, increasing the free space in the cockpit and achieving complete release of the interior space of the cockpit. It supports zero-gravity seat reclining, meets the needs of intelligent cockpit, and can integrate more functions to improve the user experience.

[0035] In some embodiments, there are two main handwheels 1, which are spaced apart and distributed opposite each other along a first direction. There are two sets of side handwheels 2, which are spaced apart along a second direction. Each set of side handwheels 2 includes a first side handwheel 21 and a second side handwheel 22. The first side handwheel 21 and the second side handwheel 22 are adapted to be rotatable about the second direction to open away from each other or fold closer to each other. The first direction and the second direction intersect and are both perpendicular to the front and back directions.

[0036] For example, such as Figure 3 and Figure 4As shown, the first direction can be the vertical direction of the steering wheel 100. One main handwheel 1 can be located above the steering wheel 100, and the other main handwheel 1 can be located below the steering wheel 100. That is, the two main handwheels 1 can be spaced apart and distributed opposite each other along the vertical direction of the steering wheel 100 to maintain the overall symmetry and aesthetics of the steering wheel 100 and facilitate folding. When the steering wheel 100 needs to be unfolded, the two main handwheels 1 can extend backward along the front-back direction of the steering wheel 100 so that the two main handwheels 1 can reach the unfolded position; when the steering wheel 100 needs to be folded, the two main handwheels 1 can retract forward along the front-back direction of the steering wheel 100 to reach the folded position.

[0037] The two sets of side handwheels 2 are the parts that the driver directly holds while driving the vehicle. The driver holds each of the two sets of side handwheels 2 with their left and right hands respectively, causing the steering wheel 100 to rotate as a whole, thus turning the vehicle. The two sets of side handwheels 2 are spaced apart and opposite each other along a second direction. For example, as shown... Figure 3 and Figure 4 As shown, the second direction can be the horizontal direction of the steering wheel 100, that is, the left and right direction of the steering wheel 100. One set of side handwheels 2 can be located on the left side of the steering wheel 100, and the other set of side handwheels 2 can be located on the right side of the steering wheel 100. That is, the two sets of side handwheels 2 are distributed opposite each other at intervals along the left and right direction of the steering wheel 100, so as to maintain the overall symmetry and aesthetics of the steering wheel 100 and facilitate folding, storage and gripping while driving.

[0038] Each set of side handwheels 2 includes a first side handwheel 21 and a second side handwheel 22. The first side handwheel 21 and the second side handwheel 22 are adapted to rotate around a second direction to open away from each other or fold closer to each other, and are both adapted to selectively retract or extend in the front-back direction. The first direction intersects the second direction and is perpendicular to the front-back direction. Specifically, the first direction is the up-down direction of the steering wheel 100, which is the vertical diameter along the surface of the steering wheel 100; the second direction is the left-right direction of the steering wheel 100, which is the lateral diameter along the surface of the steering wheel 100; and the front-back direction is the front-back direction of the steering wheel 100, which is perpendicular to the surface of the steering wheel 100. That is, the first direction intersects the second direction perpendicularly, and the first direction is perpendicular to the front-back direction, and the second direction is perpendicular to the front-back direction.

[0039] It should be noted that when the steering wheel 100 is actually installed on the vehicle, the steering wheel 100 surface is tilted upwards at the top (towards the rear of the vehicle) and downwards (towards the front of the vehicle) relative to the vehicle's front-rear direction, forming an angle with the horizontal plane. The steering wheel 100 surface is perpendicular to the steering column. In other words, the front-rear direction of the steering wheel 100 is along the axis of the steering column and forms an acute angle with the vehicle's front-rear direction. The vertical direction of the steering wheel 100 also forms an angle with the vertical direction of the vehicle. The first side handwheel 21 and the second side handwheel 22 can rotate around the center line in the left and right directions. When the steering wheel 100 needs to be folded, the first side handwheel 21 and the second side handwheel 22 can both rotate around the left and right directions to bring them closer together for folding and closing, reaching the folded state b. The folded and closed first side handwheel 21 and the second side handwheel 22 can retract forward along the front and back direction of the steering wheel 100 so that the first side handwheel 21 and the second side handwheel 22 can reach the storage position. When the steering wheel 100 needs to be unfolded, the first side handwheel 21 and the second side handwheel 22 can both rotate around the left and right directions to move them away from each other and can extend backward along the front and back direction of the steering wheel 100 so that the first side handwheel 21 and the second side handwheel 22 can reach the unfolded position.

[0040] In some alternative embodiments, the first direction may not intersect the second direction perpendicularly.

[0041] In a specific embodiment, such as Figure 3As shown, the two main handwheels 1 can be the first main handwheel 11 and the second main handwheel 12, respectively. The first side handwheel 21 and the second side handwheel 22 of one set of side handwheels 2 can be the second handwheel 21a and the third handwheel 22a, respectively. The first side handwheel 21 and the second side handwheel 22 of another set of side handwheels 2 can be the fourth handwheel 21b and the fifth handwheel 22b, respectively. The first main handwheel 11 is located above the second main handwheel 12. The second handwheel 21a and the fourth handwheel 21b are distributed opposite each other along the second direction, and the third handwheel 22a and the fifth handwheel 22b are distributed opposite each other along the second direction. In the distribution, one end of the second handwheel 21a is selectively connected to one end of the first main handwheel 11, one end of the fourth handwheel 21b is selectively connected to the other end of the first main handwheel 11, one end of the third handwheel 22a is selectively connected to one end of the second main handwheel 12, one end of the fifth handwheel 22b is selectively connected to the other end of the second main handwheel 12, the other end of the third handwheel 22a is movably connected to the other end of the second handwheel 21a, and the other end of the fourth handwheel 21b is movably connected to the other end of the fifth handwheel 22b. The steering wheel 100 can initially be in the unfolded position. During the process of the steering wheel 100 changing from the unfolded state a to the folded state b, the two ends of the first master wheel 11 need to be disconnected from the second master wheel 21a and the fourth master wheel 21b. At the same time, the two ends of the second master wheel 12 are disconnected from the third master wheel 22a and the fifth master wheel 22b. This allows the first master wheel 11 and the second master wheel 12 to be free from the constraints of the third master wheel 22a and the fourth master wheel 21b. The second master wheel 12 is also free from the constraints of the third master wheel 22a and the fifth master wheel 22b. As a result, the first master wheel 11 and the second master wheel 12 can move independently, and the second master wheel 21a, the third master wheel 22a, the fourth master wheel 21b and the fifth master wheel 22b can move independently, thus enabling the steering wheel 100 to be folded and stored in a smaller volume.

[0042] Further, refer to Figure 3 As shown, the steering wheel 100 also includes a mounting base 3, which provides mounting positions for the main handwheel 1, the first side handwheel 21, and the second side handwheel 22, and supports the main handwheel 1, the first side handwheel 21, and the second side handwheel 22 to ensure that the two main handwheels 1 and the two sets of side handwheels 2 are installed stably and can move stably.

[0043] The main handwheel 1, the first side handwheel 21, and the second side handwheel 22 are all movable relative to the mounting base 3, and the mounting base 3 is used to guide the movement of the main handwheel 1, the first side handwheel 21, and the second side handwheel 22. That is, when the main handwheel 1, the first side handwheel 21, and the second side handwheel 22 are movable relative to the mounting base 3 to unfold or fold, the mounting base 3 can guide the movement of the main handwheel 1, the first side handwheel 21, and the second side handwheel 22 to ensure that the main handwheel 1, the first side handwheel 21, and the second side handwheel 22 can move stably in the set direction, so as to achieve precise unfolding to the unfolded position and precise folding to the folded storage position, preventing jamming, stopping, or interference with other structures during movement, which could produce abnormal noise and affect driving safety.

[0044] In practice, such as Figure 2 As shown, the mounting base 3 can be connected to the instrument panel 200 and can move relative to the instrument panel 200 so that the folded steering wheel 100 can be stored inside the instrument panel 200. Since the steering wheel 100 in the folded state is small in size, there will be no jamming problem during the storage process in the instrument panel 200. It can be completely stored inside the instrument panel 200, realizing the complete release of cockpit space.

[0045] In some embodiments, at least one of the following is satisfied: A1, such as Figure 3 and Figure 7 As shown, the steering wheel 100 also includes a first drive mechanism 4, which is poweredly connected to the main handwheel 1 and is used to drive the main handwheel 1 to move in the front-rear direction relative to the mounting base 3.

[0046] For example, the first drive mechanism 4 is the power source of the main handwheel 1, which can provide power to the main handwheel 1. When the first drive mechanism 4 is in operation, it can transmit power to the main handwheel 1 to drive the main handwheel 1 to perform linear telescopic movement relative to the mounting base 3 in the front-rear direction of the steering wheel 100.

[0047] When it is necessary to switch the steering wheel 100 from the unfolded state a to the retracted state, the first drive mechanism 4 can operate to drive the main handwheel 1 to move forward relative to the mounting base 3 until it moves to the retracted position, thereby retracting the steering wheel; when it is necessary to switch the steering wheel 100 from the retracted state to the unfolded state a, the first drive mechanism 4 can operate to drive the main handwheel 1 to move backward relative to the mounting base 3 until it moves to the unfolded position, thereby unfolding the steering wheel.

[0048] In some examples, the first drive mechanism 4 can be configured as a drive motor and lead screw nut structure.

[0049] In some alternative examples, the first drive mechanism 4 can also be configured as a linear motor module.

[0050] In some alternative examples, the first drive mechanism 4 can also be configured as a drive motor and a gear rack structure, with a drive gear on the motor shaft of the drive motor and a drive rack on the main handwheel 1, the drive gear meshing with the drive rack.

[0051] In some alternative examples, the first drive mechanism 4 can also be configured as a linear hydraulic cylinder or a pneumatic cylinder, the cylinder body can be fixed to the mounting base 3, and the piston rod can be directly connected to the main handwheel 1 or connected through a slider.

[0052] Therefore, the first drive mechanism 4 can drive the main handwheel 1 to perform linear telescopic movement relative to the mounting base 3 in the front-rear direction of the steering wheel 100.

[0053] A2, such as Figure 11 As shown, the steering wheel 100 also includes a second drive mechanism 5, which is poweredly connected to the first side handwheel 21 and the second side handwheel 22. That is, the second drive mechanism 5 is poweredly connected to both the first side handwheel 21 and the second side handwheel 22, and is used to drive the first side handwheel 21 and the second side handwheel 22 to move relative to the mounting base 3 in the front-back direction.

[0054] For example, the second drive mechanism 5 is the power source for the first side handwheel 21 and the second side handwheel 22. It can provide power to the first side handwheel 21 and the second side handwheel 22. When the second drive mechanism 5 is in operation, it can transmit power to the first side handwheel 21 and the second side handwheel 22 to drive the first side handwheel 21 and the second side handwheel 22 to move linearly and telescopically relative to the mounting base 3 in the front and rear direction of the steering wheel 100.

[0055] When the steering wheel 100 needs to be switched from the unfolded state a to the retracted state, the second drive mechanism 5 can operate to drive the first side handwheel 21 and the second side handwheel 22 to move forward relative to the mounting base 3 until they move to the retracted position, thereby realizing the extension and retraction of the first side handwheel 21 and the second side handwheel 22; when the steering wheel 100 needs to be switched from the retracted state to the unfolded state a, the second drive mechanism 5 can operate to drive the first side handwheel 21 and the second side handwheel 22 to move backward relative to the mounting base 3 until they move to the unfolded position, thereby realizing the extension and retraction of the first side handwheel 21 and the second side handwheel 22.

[0056] In some examples, the second drive mechanism 5 can be configured as a drive motor and lead screw nut structure.

[0057] In some alternative examples, the second drive mechanism 5 can also be configured as a linear motor module.

[0058] In some alternative examples, the second drive mechanism 5 can also be configured as a drive motor and a gear rack structure, with a drive gear on the motor shaft of the drive motor and a drive rack on the first side handwheel 21 and the second side handwheel 22, the drive gear meshing with the drive rack.

[0059] In some alternative examples, the second drive mechanism 5 can also be configured as a linear hydraulic cylinder or a pneumatic cylinder, the cylinder body of which can be fixed to the mounting base 3, and the piston rod can be directly or through a slider connected to the first side handwheel 21 and the second side handwheel 22.

[0060] Therefore, the second drive mechanism 5 can drive the first side handwheel 21 and the second side handwheel 22 to move linearly and extend and retract relative to the mounting base 3 in the front and rear direction of the steering wheel 100, thereby improving the synchronicity of the movement of the first side handwheel 21 and the second side handwheel 22 and preventing the first side handwheel 21 and the second side handwheel 22 from moving asynchronously and getting stuck, thus making it impossible to accurately reach both sides of the column.

[0061] A3, such as Figure 23 As shown, the steering wheel 100 also includes a third drive mechanism 6, which is poweredly connected to the first side handwheel 21 and the second side handwheel 22, and is used to drive the first side handwheel 21 and the second side handwheel 22 to rotate relative to the mounting base 3.

[0062] For example, the third drive mechanism 6 is the power source for the first side handwheel 21 and the second side handwheel 22. It can provide power to the first side handwheel 21 and the second side handwheel 22. When the second drive mechanism 5 is in operation, it can transmit power to the first side handwheel 21 and the second side handwheel 22 to drive the first side handwheel 21 and the second side handwheel 22 to rotate synchronously relative to the mounting base 3 in the second direction of the steering wheel 100.

[0063] When it is necessary to switch the steering wheel 100 from the unfolded state a to the folded state b, the third drive mechanism 6 can operate to drive the first side handwheel 21 and the second side handwheel 22 to rotate forward relative to the mounting base 3 around their respective axes and rotate to the folded position, thereby realizing the rotational folding of the first side handwheel 21 and the second side handwheel 22; when it is necessary to switch the steering wheel 100 from the folded state b to the unfolded state a, the third drive mechanism 6 can operate to drive the first side handwheel 21 and the second side handwheel 22 to rotate backward relative to the mounting base 3 around their respective axes and rotate to the unfolded position, thereby realizing the rotational opening of the first side handwheel 21 and the second side handwheel 22.

[0064] In some examples, the third drive mechanism 6 can be configured as a drive motor and gear set.

[0065] In some alternative examples, the third drive mechanism 6 may also be configured as a rotary hydraulic cylinder or a pneumatic cylinder.

[0066] Therefore, the third drive mechanism 6 can drive the first side handwheel 21 and the second side handwheel 22 to rotate synchronously relative to the mounting base 3 around their respective axes, which further improves the synchronicity of the movement of the first side handwheel 21 and the second side handwheel 22, and prevents the first side handwheel 21 and the second side handwheel 22 from jamming due to asynchronous movement, thus making it impossible to accurately reach both sides of the column.

[0067] In some embodiments, reference Figure 7 , Figure 10 , Figure 11 and Figure 20 As shown, the first drive mechanism 4 includes a first drive member 41 and a first sliding block 42. The output end of the first drive member 41 is connected to a first lead screw 411, which can extend along the front-rear direction of the steering wheel 100. The first lead screw 411 and the first sliding block 42 are threaded together, that is, the outer peripheral wall of the first lead screw 411 is provided with an external thread, and the first sliding block 42 is provided with a first through hole and the inner wall of the first through hole is provided with an internal thread. Thus, one end of the first lead screw 411 can pass through the first through hole, and the threaded engagement between the external and internal threads is achieved, thereby enabling the first sliding block 42 to move linearly along the axial direction of the first lead screw 411. The first sliding block 42 is connected to the main handwheel 1, so that when the first sliding block 42 moves, it can drive the main handwheel 1 to move linearly along the axial direction of the first lead screw 411.

[0068] The first driving member 41 is used to drive the first lead screw 411 to rotate, thereby pushing the first sliding block 42 to move in the front-back direction. That is, the first driving member 41 is a power source. When it is running, it can transmit power to the first lead screw 411 to drive the first lead screw 411 to rotate. When the first lead screw 411 rotates, it can drive the first sliding block 42 to move in the front-back direction of the steering wheel 100. When the first sliding block 42 moves, it can drive the main handwheel 1 to move together in the front-back direction of the steering wheel 100, thereby converting the rotational motion of the first lead screw 411 into the linear motion of the main handwheel 1, realizing the extension and retraction motion of the main handwheel 1 in the front-back direction, which is flexible, convenient and easy to implement.

[0069] In practical design, the first driving component 41 can be constructed as a drive motor, such as a DC rotary motor, an AC asynchronous motor, an AC synchronous motor, a stepper motor, a servo motor, etc.

[0070] In some embodiments, reference Figure 12 As shown, the first sliding block 42 is rotatably connected to the main handwheel 1 around the first axis 71a. The first axis 71a extends along the second direction so that the main handwheel 1 can rotate relative to the first sliding block 42 around the second direction, thereby reducing the space occupied by the main handwheel 1 in the first direction after it is stored, which is beneficial to reduce the size of the steering wheel 100 in the first direction.

[0071] Among them, such as Figure 10 and Figure 11 As shown, the main handwheel 1 is also provided with a first guide post 13, which is used to guide the movement of the main handwheel 1. The first guide post 13 can extend along the second direction. The first guide post 13 is spaced apart from the first axis 71a to avoid interference between the first guide post 13 and the first axis 71a. The mounting base 3 is provided with a first guide groove 31, which can extend along the front-rear direction. The first guide groove 31 is adapted to the first guide post 13. The two ends of the first guide post 13 in the second direction can respectively extend into the first guide groove 31 and slide along the extension direction of the first guide groove 31 to achieve the guiding cooperation between the first guide groove 31 and the first guide post 13 to guide the movement of the main handwheel 1. Thus, when the first sliding block 42 moves linearly along the front-rear direction of the steering wheel 100, it can drive the main handwheel 1 to slide along the extension direction of the first guide groove 31, thereby guiding the main handwheel 1 and enabling the main handwheel 1 to move stably in the front-rear direction, preventing it from sliding or deviating, and improving the movement stability and reliability of the main handwheel 1.

[0072] It is understandable that the extension length of the first guide groove 31 is the extension and retraction stroke of the main handwheel 1. When the first guide post 13 moves from the rear end of the first guide groove 31 to press against the front end of the first guide groove 31, the retraction movement of the main handwheel 1 stops, and it reaches the retracted position. When the first guide post 13 moves from the front end of the first guide groove 31 to press against the rear end of the first guide groove 31, the extension movement of the main handwheel 1 stops, and it reaches the extended position.

[0073] Specifically, such as Figure 12 and Figure 13 As shown, the first sliding block 42 and the main handwheel 1 are rotatably connected around the first rotating shaft 71. The first rotating shaft 71 extends along the second direction, and the axis of the first rotating shaft 71 is the first axis 71a. The first rotating shaft 71 passes through the first sliding block 42 and rotates within the first sliding block 42. The two ends of the first rotating shaft 71 can be relatively fixed to the main handwheel 1, or the first rotating shaft 71 and the first sliding block 42 can be relatively fixed, and the two ends of the first rotating shaft 71 can be rotatably connected to the main handwheel 1, thereby realizing the relative rotation of the first sliding block 42 and the main handwheel 1.

[0074] In some alternative embodiments, such as Figure 13 As shown, a first sliding guide rail 33 extending in the front-back direction can be provided on the mounting base 3, and a first sliding guide groove can be provided on the first sliding block 42. The first sliding guide rail 33 and the first sliding guide groove are slidably engaged so that the first sliding block 42 can slide stably along the first sliding guide rail 33, thereby driving the main handwheel 1 to move stably in the front-back direction, improving the stability and reliability of the movement of the first sliding block 42.

[0075] In some alternative embodiments, such as Figure 11 As shown, the first guide groove 31 may include a first guide groove 311 and a second guide groove 312. The first guide groove 311 and the second guide groove 312 are connected in the front-rear direction, and the first guide groove 311 extends in a straight line in the front-rear direction. The second guide groove 312 extends at an angle relative to the first guide groove 311 towards the other master wheel 1. Taking the first master wheel 11 as an example, the second guide groove 312 extends at a downward angle relative to the first guide groove 311. Taking the second master wheel 12 as an example, the second guide groove 312 extends at an upward angle relative to the first guide groove 311. Thus, when the steering wheel 100 is stored, the first... The sliding block 42 can first drive the first guide post 13 of the main handwheel 1 to slide in the first guide groove 311, so that the main handwheel 1 slides forward in a straight line. When the first guide post 13 slides into the second guide groove 312, the first sliding block 42 can drive the first guide post 13 of the main handwheel 1 to slide in the second guide groove 312, so that the first main handwheel 11 can slide forward and downward, and the second main handwheel 12 can slide forward and upward. This realizes the storage of the two main handwheels 1 in the front-back direction and the first direction, reduces the size occupied by the two main handwheels 1 in the front-back direction and the first direction of the steering wheel 100, and makes the overall volume of the steering wheel 100 smaller.

[0076] In some embodiments, reference Figure 14 and Figure 16 As shown, the second drive mechanism 5 includes a second drive member 51 and a second sliding block 52. The output end of the second drive member 51 is connected to a second lead screw 511, which extends along the front-rear direction of the steering wheel 100. The second lead screw 511 and the second sliding block 52 are threaded together, that is, the outer peripheral wall of the second lead screw 511 is provided with an external thread, and the second sliding block 52 is provided with a second through hole and the inner wall of the second through hole is provided with an internal thread. Thus, one end of the second lead screw 511 can pass through the second through hole, and the threaded engagement between the external and internal threads is achieved, thereby enabling the second sliding block 52 to move linearly along the axial direction of the second lead screw 511. The second sliding block 52 can be connected to a first side handwheel 21 and a second side handwheel 22. Thus, when the second sliding block 52 moves, it can drive the first side handwheel 21 and the second side handwheel 22 to move linearly along the axial direction of the second lead screw 511.

[0077] The second driving member 51 drives the second lead screw 511 to rotate, thereby pushing the second sliding block 52 to move in the front-back direction. The second sliding block 52 drives the first side handwheel 21 and the second side handwheel 22 to move in the front-back direction. In other words, the second driving member 51 is a power source. When it operates, it can transmit power to the second lead screw 511 to drive the second lead screw 511 to rotate. When the second lead screw 511 rotates, it can drive the second sliding block 52 to move in the front-back direction of the steering wheel 100. When the second sliding block 52 moves, it can drive the first side handwheel 21 and the second side handwheel 22 to move together in the front-back direction of the steering wheel 100. This converts the rotational motion of the second lead screw 511 into the linear motion of the first side handwheel 21 and the second side handwheel 22, realizing the synchronous extension and retraction motion of the first side handwheel 21 and the second side handwheel 22 in the front-back direction. This is flexible, convenient, and easy to implement.

[0078] In practical design, the second drive component 51 can be constructed as a drive motor, such as a DC rotary motor, an AC asynchronous motor, an AC synchronous motor, a stepper motor, a servo motor, etc.

[0079] It should be noted that the second driving component 51 of this application can drive the first side handwheel 21 and the second side handwheel 22 of the two sets of side handwheels 2 to move synchronously, realize the linkage movement of the two sets of side handwheels 2, ensure the overall folding and storage effect, and reduce the volume after folding and storage.

[0080] In some embodiments, reference Figure 11 , Figure 12 and Figure 13 As shown, the steering wheel 100 also includes a mounting block 8. The first side handwheel 21 and the second side handwheel 22 of each group can be rotatably mounted on the mounting block 8. That is, the two first side handwheels 21 and the two second side handwheels 22 are connected to the mounting block 8 as an integral structure and can all rotate relative to the mounting block 8, so as to realize the linkage of the first side handwheels 21 and the second side handwheels 22.

[0081] refer to Figure 11 As shown, the second sliding block 52 is rotatably connected to the mounting block 8 around the second axis 72a. The second axis 72a extends along the first direction so that the mounting block 8 can rotate relative to the second sliding block 52 around the second axis 72a. In this way, the mounting block 8 can drive the first side handwheel 21 and the second side handwheel 22 of each group to rotate relative to the second sliding block 52 around the second axis 72a, thereby realizing the rotation and folding action of the first side handwheel 21 and the second side handwheel 22 of each group. This can reduce the space occupied by the two groups of side handwheels 2 after folding in the first direction, which is beneficial to reduce the size of the steering wheel 100 in the first direction.

[0082] Among them, such as Figure 12 , Figure 13As shown, the mounting block 8 is provided with a guide portion 81, which guides the movement of the first side handwheel 21 and the second side handwheel 22 of each group. The guide portion 81 and the second axis 72a can be spaced apart in the second direction to avoid interference; as shown Figures 10-14 As shown, the mounting base 3 is provided with a second guide groove 32, which can extend in the front-back direction. The second guide groove 32 is adapted to the guide part 81, which can extend into the second guide groove 32 and slide along the extension direction of the second guide groove 32 to achieve the guiding cooperation between the second guide groove 32 and the guide part 81, so as to guide the movement of the mounting block 8. Thus, when the first sliding block 42 moves linearly in the front-back direction of the steering wheel 100, it can drive the two sets of side handwheels 2 to slide along the extension direction of the second guide groove 32, thereby guiding the two sets of second guide grooves 32, so that the two sets of side handwheels 2 can move stably in the front-back direction, preventing them from sliding or deviating, and improving the movement stability and reliability of the two sets of side handwheels 2.

[0083] It is understandable that the extension length of the second guide groove 32 is the telescopic travel of each first side handwheel 21 and each second side handwheel 22. When the guide part 81 moves from the rear end of the second guide groove 32 to press against the front end of the second guide groove 32, the telescopic retraction movement of the two sets of side handwheels 2 stops, and they reach the retracted position. When the guide part 81 moves from the front end of the second guide groove 32 to press against the rear end of the second guide groove 32, the telescopic extension movement of the two sets of side handwheels 2 stops, and they reach the extended position.

[0084] Specifically, such as Figure 11 As shown, the second sliding block 52 and the mounting block 8 are rotatably connected by the second rotating shaft 72. The second rotating shaft 72 extends along the first direction, and the axis of the second rotating shaft 72 is the second axis 72a. The second rotating shaft 72 passes through the mounting block 8 and can rotate within the mounting block 8. The second rotating shaft 72 can be fixed relative to the second sliding block 52, or the second rotating shaft 72 can be fixed relative to the mounting block 8 and rotatably connected to the second sliding block 52, thereby realizing the relative rotation of the second sliding block 52 and the mounting block 8.

[0085] In actual design, the guide part 81 can be constructed as a guide block.

[0086] In some embodiments, at least one of the following is satisfied: A1, Reference Figures 21-25As shown, the third drive mechanism 6 includes a third drive member 61, which is provided with a drive gear 611. The mounting block 8 is provided with a driven gear 82. The drive gear 611 meshes with the driven gear 82. One of the first side handwheel 21 and the second side handwheel 22 is provided with a first transmission gear 211 and the other is provided with a second transmission gear 221. The first transmission gear 211 is coaxially connected with the driven gear 82, and the second transmission gear 221 meshes with the first transmission gear 211, so that the first side handwheel 21 and the second side handwheel 22 rotate closer to or further away from each other.

[0087] Specifically, the third drive unit 61 is a power source, used to provide power for the rotation of the first side handwheel 21 and the second side handwheel 22 of each group to fold or unfold. A third drive mechanism 6 can be provided for each of the two groups of side handwheels 2, so that the two drive units can respectively drive the corresponding first side handwheel 21 and second side handwheel 22 to rotate closer to or further away from each other. Figure 24 and Figure 25 As shown, the third driving member 61 is equipped with a driving gear 611, and the mounting block 8 is equipped with a driven gear 82. The driving gear 611 meshes with the driven gear 82. The first side handwheel 21 is equipped with a first transmission gear 211, and the second side handwheel 22 is equipped with a second transmission gear 221. Alternatively, the first side handwheel 21 is equipped with a second transmission gear 221, and the second side handwheel 22 is equipped with a first transmission gear 211. The first transmission gear 211 and the driven gear 82 are coaxially fixedly connected. The first transmission gear 211 and the second transmission gear 221 are distributed along the first direction and externally mesh. Therefore, when the third driving member 61 operates, it can... The drive gear 611 rotates, which in turn drives the driven gear 82 to rotate. The driven gear 82 rotates, which in turn drives the first transmission gear 211 to rotate synchronously. The first transmission gear 211 rotates, which in turn drives the second transmission gear 221 to rotate in the opposite direction. Thus, the first transmission gear 211 drives the first side handwheel 21 to rotate synchronously, and the second transmission gear 221 drives the second side handwheel 22 to rotate synchronously. This allows the first side handwheel 21 and the second side handwheel 22 of each group to move away from each other when folding and to move closer to each other when opening.

[0088] In a specific embodiment, such as Figure 24 and Figure 25As shown, the gear shaft of the first transmission gear 211 is the first gear shaft 2111, and the gear shaft of the second transmission gear 221 is the second gear shaft 2211. The first gear shaft 2111 and the second gear are arranged parallel to each other and both extend along the second direction. Both the driving gear 611 and the driven gear 82 can be constructed as bevel gears to change the direction of power transmission and reduce speed and increase torque. This makes full use of space to arrange the various gear structures, avoids structural interference, and makes the movement of the first side handwheel 21 or the second side handwheel 22 smoother. The axis of the driving gear 611 is arranged along the front-back direction, and the axis of the driven gear 82 is coaxial with the first gear shaft 2111. The first gear shaft 2111 can be fixedly connected to one of the first side handwheel 21 or the second side handwheel 22, and the second gear can be fixedly connected to the other of the first side handwheel 21 or the second side handwheel 22.

[0089] In some examples, the driven gear 82 and the first transmission gear 211 may be integral castings, and the first gear shaft 2111 and the second gear shaft 2211 may be rotatably mounted on the mounting block 8 via bearings.

[0090] In other examples, the driven gear 82 and the first transmission gear 211 can be molded from carbon fiber composite material or die-cast from magnesium alloy to reduce their weight while ensuring their structural strength and rigidity, which is conducive to achieving a lightweight design of the steering wheel 100.

[0091] A2. There are two mounting blocks 8. The two mounting blocks 8 are rotatably connected to the second sliding block 52, and the two mounting blocks 8 are connected to the two sets of side handwheels 2 respectively.

[0092] Specifically, such as Figure 21 As shown, two mounting blocks 8 are provided, distributed along the second direction. Each mounting block 8 is rotatably connected to a second sliding block 52, meaning both mounting blocks 8 can rotate relative to the second sliding block 52. Each mounting block 8 is connected to two sets of side handwheels 2. Therefore, when the second sliding block 52 slides in the front-back direction, it simultaneously drives the two mounting blocks 8 to move in the front-back direction. Consequently, each mounting block 8 drives its corresponding side handwheel 2 to move in the front-back direction, achieving linkage between the two sets of side handwheels 2. This allows the two sets of side handwheels 2 to synchronously perform retractable or extendable movements.

[0093] In a specific embodiment, such as Figure 3As shown, the mounting base 3 includes a first mounting base 34 and a second mounting base 35, which are connected along a first direction. The first mounting base 34 is used to mount the first drive mechanism 4 of the first master handwheel 11, and the second mounting base 35 is used to mount the first drive mechanism 4 of the second master handwheel 12, so that the two master handwheels 1 can be controlled independently. The second drive mechanism 5 and the third drive mechanism 6 can be installed between the first mounting base 34 and the second mounting base 35. Figure 20 As shown, both the first mounting base 34 and the second mounting base 35 are provided with a second guide groove 32. Each mounting block 8 is provided with a guide part 81 on both sides in the first direction. The two guide parts 81 are respectively guided and cooperated with the two second guide grooves 32. In this way, the first side handwheel 21 and the second side handwheel 22 of each set of side handwheels 2 can move more stably and reliably.

[0094] In actual design, the first mounting base 34 and the second mounting base 35 can be connected by detachable connection methods such as snap-fit, threaded connection, and plug-in connection to facilitate the installation, disassembly and maintenance of each drive mechanism.

[0095] In some embodiments, such as Figure 3 and Figure 4 As shown, a receiving space 37 is formed between the first mounting base 34 and the second mounting base 35. After the two main handwheels 1 and the two sets of side handwheels 2 are folded and stored, the two main handwheels 1 can be located on the surfaces of the first mounting base 34 and the second mounting base 35 that are opposite to each other, and the two sets of side handwheels 2 can be folded and stored in the receiving space 37.

[0096] In some embodiments, such as Figure 10 As shown, the second guide groove 32 can be inclined in the front-back direction. The second guide grooves 32 of the two sets of side handwheels 2 can gradually approach each other from back to front. In this way, each set of side handwheels 2 can extend and retract in the front-back direction and in the direction of approaching the other set of side handwheels 2. This can realize the extension and retraction of each set of side handwheels 2 in the front-back direction and the second direction, reduce the size occupied by the two sets of side handwheels 2 in the front-back direction and the second direction of the steering wheel 100, and make the overall volume of the steering wheel 100 smaller.

[0097] In some embodiments, such as Figure 10As shown, the mounting block 8 includes a connecting rod 83, a first mounting seat 84, and a second mounting seat 85. One end of the connecting rod 83 is rotatably connected to the second rotating shaft 72, meaning the connecting rod 83 can rotate around the second rotating shaft 72. The second rotating shaft 72 is fixed to the second sliding block 52. The other end of the connecting rod 83 is fixedly connected to the first mounting seat 84. The third driving member 61 is fixed inside the first mounting seat 84. The first mounting seat 84 is fixedly connected to the second mounting seat 85. The first transmission gear 211 and the second transmission gear 221 are rotatably mounted inside the second mounting seat 85 to protect the first transmission gear 211 and the second transmission structure. A button 851 can also be provided on the outer surface of the second mounting seat 85. The steering wheel 100 can be folded and stored by the button 851, and other functions can also be realized by the button 851.

[0098] In some examples, button 851 may be integrated with a pressure sensor or capacitive touch sensor to replace a traditional mechanical switch, enabling force feedback or gesture control and improving the convenience of folding or unfolding the steering wheel 100.

[0099] In some alternative embodiments, an LED ambient light strip can be embedded in the edge of the main handwheel 1 or the side handwheel 2. The light displayed by the light strip can change color according to the driving mode, or flash when folded and stored to indicate that the steering wheel 100 is in the folded and stored state, thereby enhancing the aesthetics of the interior.

[0100] In some embodiments, such as Figures 1-4 As shown, the steering wheel 100 also includes a central module 9, which is connected to the front of the mounting base 3. The central module 9 can integrate other modules such as an airbag, a touch screen, a horn, and a wireless charging phone holder. When the steering wheel 100 is folded, the main handwheel 1 and the side handwheel 2 can be located behind the central module 9.

[0101] In some embodiments, reference Figures 21-23 As shown, each main handwheel 1 is provided with a plug-in structure 14. The plug-in structure 14 includes a plug-in drive 141 and a plug-in 142. The plug-in drive 141 drives the plug-in 142 to extend and retract relative to the main handwheel 1 so as to selectively plug into and connect with the side handwheel 2.

[0102] Specifically, the plug-in drive 141 can be connected to the plug-in 142. The plug-in drive 141 can provide plug-in power, which can drive the plug-in 142 to extend and retract relative to the main handwheel 1 in the second direction. When the plug-in 142 is extended relative to the main handwheel 1, the end of the plug-in 142 can extend into the first side handwheel 21 or the second side handwheel 22 to plug and connect with the first side handwheel 21 or the second side handwheel 22, thereby achieving relative fixation between the main handwheel 1 and the first side handwheel 21 or the second side handwheel 22. When the plug-in 142 is retracted relative to the main handwheel 1, the end of the plug-in 142 can leave the first side handwheel 21 or the second side handwheel 22 to plug and separate from the first side handwheel 21 or the second side handwheel 22, thereby achieving connection and separation between the main handwheel 1 and the first side handwheel 21 or the second side handwheel 22.

[0103] like Figure 21 As shown, two plug-in structures 14 can be provided inside the first main handwheel 11. The two plug-in structures 14 are installed in opposite directions so that one plug-in member 142 can be directly opposite the first side handwheel 21 of a set of side handwheels 2, and the other plug-in member 142 can be directly opposite the first side handwheel 21 of another set of side handwheels 2. Thus, the plug-in member 142 can be simultaneously driven to extend and retract by the two plug-in driving members 141, so that both ends of the first main handwheel 11 can be simultaneously connected to or disconnected from the two first side handwheels 21 respectively. Two plug-in structures 14 can be provided inside the second main handwheel 12. The two plug-in structures 14 are installed in opposite directions so that one plug-in member 142 can be directly opposite the second side handwheel 22 of a set of side handwheels 2, and the other plug-in member 142 can be directly opposite the second side handwheel 22 of another set of side handwheels 2. Thus, the plug-in member 142 can be simultaneously driven to extend and retract by the two plug-in driving members 141, so that both ends of the second main handwheel 12 can be simultaneously connected to or disconnected from the two second side handwheels 22 respectively. This can further improve the synchronicity of folding and storage movements.

[0104] Therefore, the main handwheel 1 can be selectively connected to the first side handwheel 21 or the second side handwheel 22 through the plug-in structure 14, which can be quickly connected or disconnected, making it flexible and convenient and improving the folding and storage efficiency.

[0105] In some specific embodiments, the plug-in drive 141 can be configured as an electric cylinder, and the output shaft of the electric cylinder can be configured as a plug-in member 142. A plug-in protrusion can be provided on the outer peripheral wall or end face of the plug-in member 142, and a plug-in mating groove can be provided on the first side handwheel 21 and the second side handwheel 22. The output shaft of the electric cylinder can extend and retract axially so that the plug-in protrusion extends into the first side handwheel 21 or the second side handwheel 22 and plugs into the plug-in mating part of the first side handwheel 21 or the second side handwheel 22, or the plug-in protrusion disengages from the plug-in mating part, thereby realizing that the main handwheel 1 can be selectively plugged into and connected to the first side handwheel 21 or the second side handwheel 22.

[0106] In practical design, the interlocking protrusion and the interlocking groove can be constructed as a mortise and tenon structure.

[0107] In some examples, a locking pin with a spring can be provided on the output shaft of the electric cylinder, a locking hole can be provided at the corresponding position of the first side handwheel 21 or the second side handwheel 22, and an electromagnet can be provided on the output shaft, and a permanent magnet can be provided at the corresponding position of the first side handwheel 21 or the second side handwheel 22. Thus, electromagnetic attraction or electromagnetic repulsion can be generated by energizing, so that the locking pin can be inserted into or disengaged from the locking hole, thereby enabling the main handwheel 1 to selectively connect with the first side handwheel 21 or the second side handwheel 22, improving the reliability of the connection.

[0108] In some other specific embodiments, the plug-in drive 141 can be configured as an electromagnetic clutch. The stator of the electromagnetic clutch can be embedded in the first side handwheel 21 or the second side handwheel 22, and the rotor of the electromagnetic clutch can be connected to the drive shaft. When energized, the main handwheel 1 can be connected to the first side handwheel 21 or the second side handwheel 22 by magnetic attraction. When de-energized, the main handwheel 1 can be disconnected from the first side handwheel 21 or the second side handwheel 22.

[0109] The present invention also proposes a vehicle.

[0110] According to an embodiment of the present invention, a vehicle includes an instrument panel 200 and a steering wheel 100 of any of the above embodiments. The instrument panel 200 has a storage space 201 formed therein, and the instrument panel 200 is provided with a clearance opening 202 communicating with the storage space 201. The steering wheel 100 is configured to be stored from the clearance opening 202 into the storage space 201 and the clearance opening 202 is closed after switching to the folding state b.

[0111] Specifically, such as Figure 1 and Figure 2 As shown, the vehicle includes an instrument panel 200 and a steering wheel 100. The instrument panel 200 has a recess for storing the steering wheel 100 in its folded state (b). The instrument panel 200 has a clearance opening 202 communicating with a storage space 201. The clearance opening 202 is used to avoid the mounting base 3. The clearance opening 202 matches the shape and size of the central module 9. After the steering wheel 100 is switched to its folded state (b), the mounting base 3 can extend and retract relative to the instrument panel 200 to retract into the storage space 201. The central module 9 can also block the clearance opening 202, thus achieving storage of the steering wheel 100 within the instrument panel 200. Simultaneously, closing the clearance opening 202 on the instrument panel 200 achieves a visually seamless effect, enhancing the overall integrity and aesthetics of the vehicle's interior, and ensuring that the folded steering wheel 100 does not encroach on the interior space, completely freeing up interior space, significantly improving space utilization and comfort, and meeting diverse usage needs.

[0112] The vehicle in this application supports autonomous driving mode.

[0113] In practice, such as Figure 1 As shown, the instrument panel 200 may include an upper instrument panel 203 and a lower instrument panel 204, and the clearance opening 202 is formed by the upper instrument panel 203 and the lower instrument panel 204.
