Description

Technical Field

[0001] This application relates to the field of electronic technology, and more particularly to a steering wheel assembly and a vehicle. Background Technology

[0002] Related technology provides a foldable steering wheel that can rotate between an unfolded and a folded state about a horizontal axis. In the unfolded state, the steering wheel and steering column are coaxial; in the folded state, the axes of the steering wheel and steering column are intersected and can fold relative to the support frame, thereby reducing the horizontal space occupied by the steering wheel. However, this solution only includes a locking mechanism to lock the steering wheel in the fully unfolded and fully folded positions; it cannot lock the steering wheel during folding, resulting in the steering wheel not being effectively positioned during folding.

[0081] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0082] Firstly, please see Figures 1 to 23This application provides a steering wheel assembly 100. The steering wheel assembly 100 includes a mounting base 1, a steering wheel assembly 20, and a locking mechanism 4. The steering wheel assembly 20 is rotatably mounted on the mounting base 1. The locking mechanism 4 includes a locking member 410 movably mounted on the mounting base 1. The locking member 410 is configured to selectively and separably couple with at least three positions of the steering wheel assembly 20 in the rotation direction of the steering wheel assembly 20 to lock the steering wheel assembly 20.

[0083] The steering wheel assembly 20 is a structure within the steering wheel assembly 100 used for driver operation. The steering wheel assembly 20 is mounted on the fixed base 1 and can rotate relative to the fixed base 1. Specifically, rotating the steering wheel assembly 20 allows the steering wheel assembly 100 to switch between an unfolded state and a folded state. Typically, in the unfolded state, the steering wheel assembly 100 occupies a larger space, while in the folded state, the overall volume of the steering wheel assembly 100 is smaller, and its space occupation is also less.

[0084] The locking mechanism 4 is used to prevent the steering wheel assembly 20 from rotating and to fix the steering wheel assembly 20. Specifically, the locking mechanism 4 includes a locking member 410, which is movably disposed on the fixed base 1, so that the position of the locking member 410 on the fixed base 1 can be changed. For example, the locking member 410 can be slidably disposed on the fixed base 1 or rotatably disposed on the fixed base 1.

[0085] By adjusting the position of the locking member 410 on the fixed base 1, the locking member 410 and the steering wheel assembly 20 can be separably coupled. Here, separable coupling means that the locking member 410 can be decoupled from the steering wheel assembly 20 after coupling. When the locking member 410 is coupled to the steering wheel assembly 20, the steering wheel assembly 20 is locked by the locking member 410, and the steering wheel assembly 20 cannot rotate relative to the fixed base 1. When the locking member 410 is decoupled from the steering wheel assembly 20, for example, when the locking member 410 separates from the steering wheel assembly 20, the steering wheel assembly 20 can no longer rotate relative to the fixed base 1.

[0086] Furthermore, the locking member 410 is also configured to be selectively and separably coupled to at least three positions of the steering wheel assembly 20. These at least three positions are different locations of the steering wheel assembly 20 in its rotation direction. The steering wheel assembly 20 includes at least a first extreme position and a second extreme position in its rotation direction. The first extreme position and the second extreme position are spaced apart on the steering wheel assembly 20. When the locking member 410 is coupled to the first extreme position of the steering wheel assembly 20, the steering wheel assembly 100 is fixed in the unfolded state; when the locking member 410 is coupled to the second extreme position of the steering wheel assembly 20, the steering wheel assembly 100 is fixed in the folded state. When the locking member 410 is configured to be separably coupled to at least three positions of the steering wheel assembly 20, at least one of these positions is between the first extreme position and the second extreme position. That is, the locking member 410 can couple to the steering wheel assembly 20 at least once during the folding process of the steering wheel assembly 20, i.e., lock the steering wheel assembly 20 at least once. It should be noted that the locking member 410 can be separably coupled to at least three positions of the steering wheel assembly 20. These at least three positions may include at least one of the first limit position and the second limit position, or may not include the first limit position and the second limit position.

[0087] In the steering wheel assembly 100 provided in this application embodiment, since the steering wheel assembly 20 can rotate relative to the fixed seat 1, the relative position between the steering wheel assembly 20 and the fixed seat 1 can be adjusted, thereby enabling the steering wheel assembly 100 to have multiple states, including an unfolded state and a folded state. At the same time, the steering wheel assembly 100 is also provided with a locking mechanism 4 including a locking member 410. The locking member 410 is movably disposed on the fixed seat 1 and can be coupled with the steering wheel assembly 20 by moving its position to lock the steering wheel assembly 20. The locking member 410 can selectively be separated and coupled with the steering wheel assembly 20 at least three positions in its rotation direction. That is to say, the locking member 410 can couple with the steering wheel assembly 20 to lock the steering wheel assembly 20 at least once during the folding process of the steering wheel assembly 20.

[0088] In some implementations, please refer to Figure 3 The steering wheel assembly 20 includes a pivot 2 and a steering wheel 3; the pivot 2 is rotatably mounted on a fixed base 1; the steering wheel 3 is fixedly connected to the pivot 2 so as to rotate relative to the fixed base 1 under the drive of the pivot 2.

[0089] On the fixed base 1, the rotation of the rotating shaft 2 specifically means rotating around the central axis of the rotating shaft 2. The steering wheel 3 is connected to the rotating shaft 2, specifically the steering wheel 3 is fixedly connected to the rotating shaft 2. When the rotating shaft 2 rotates, the steering wheel 3 rotates synchronously. With the fixed base 1 as a reference, the steering wheel 3 flips relative to the fixed base 1.

[0090] As an example, in the initial state, the normal direction of the plane containing the handwheel of the steering wheel 3 coincides with or is parallel to the normal direction of the fixed base 1, i.e., the angle between them is 0°, and the direction of the shaft 2 is perpendicular to the normal direction of the fixed base 1. When the shaft 2 rotates 90°, the steering wheel 3 also rotates 90° synchronously, and the steering wheel 3 flips to its limit position. At this time, the normal direction of the plane containing the handwheel of the steering wheel 3 is perpendicular to the normal direction of the fixed base 1, i.e., the angle between them is 90°. It should be noted that in other examples, in the initial state, the angle between the normal direction of the plane containing the handwheel of the steering wheel 3 and the normal direction of the fixed base 1 can also be other values, such as 5° or 30°; when the steering wheel 3 flips to its limit position, the angle between the normal direction of the plane containing the handwheel of the steering wheel 3 and the normal direction of the fixed base 1 can also be other values, such as 95° or 150°, etc., which are not limited here.

[0091] By using the pivot 2 to rotate the steering wheel 3 relative to the fixed seat 1, the position of the steering wheel 3 can be adjusted, thereby allowing the steering wheel assembly 100 to switch between an unfolded state and a folded state.

[0092] In some embodiments, the locking element 410 is configured to selectively and separably couple with at least three locations in the circumferential direction of the pivot 2 to lock the pivot 2. Locking the pivot 2 by coupling the locking element 410 with the pivot 2, i.e., locking the steering wheel assembly 20.

[0093] By adjusting the position of the locking element 410 on the fixed base 1, the locking element 410 can be separated from the rotating shaft 2, or coupled to the rotating shaft 2. That is, the locking element 410 is configured to selectively couple with the rotating shaft 2, and its position on the fixed base 1 can also be adjusted to separate it from the rotating shaft 2. When the locking element 410 is separated from the rotating shaft 2, both can move independently. When coupled, the locking element 410 interferes with the rotation of the rotating shaft 2 and prevents it from rotating, thus locking the rotating shaft 2. Coupling of the locking element 410 with the rotating shaft 2 refers to a force interaction between them. The coupling can be achieved through one or more of engagement, snap-fit, and interference fit. As an example, the locking element 410 and the rotating shaft 2 can be coupled in a manner similar to a clutch.

[0094] When the pivot 2 is locked, the steering wheel 3 stops rotating relative to the fixed seat 1, and the position of the steering wheel 3 is fixed. The locking member 410 can couple with at least three positions in the circumferential direction of the pivot 2 to lock the pivot 2, so that the steering wheel 3 can be fixed in at least three positions.

[0095] As an example, in the initial state, the angle between the normal direction of the plane containing the handwheel of steering wheel 3 and the normal direction of the fixed base 1 is 0°. In this state, the pivot 2 can be locked to prevent the steering wheel 3 from flipping. After the pivot 2 is rotated 15° and locked, the angle between the normal direction of the plane containing the handwheel of steering wheel 3 and the normal direction of the fixed base 1 becomes 15°, meaning the steering wheel 3 is fixed in the position after being flipped 15°. After the pivot 2 is rotated 60° and locked, the steering wheel 3 is fixed in the position after being flipped 60°. Alternatively, the pivot 2 can be rotated 90° and locked, meaning the steering wheel 3 is fixed after reaching its extreme position.

[0096] In other words, in the steering wheel assembly 100, by using the pivot 2 to drive the steering wheel 3 to rotate relative to the fixed seat 1, the position of the steering wheel 3 can be adjusted, thereby allowing the steering wheel assembly 100 to have multiple states, such as an unfolded state and a folded state. At the same time, the steering wheel assembly 100 is also provided with a locking mechanism 4 including a locking member 410. The locking member 410 is movably mounted on the fixed seat 1 and is coupled to the pivot 2 to lock the pivot 2, thereby preventing the steering wheel 3 from rotating further and fixing the steering wheel 3.

[0097] The locking element 410 is configured to be separably coupled to the rotating shaft 2. That is, the locking element 410 can be coupled to the rotating shaft 2 to lock it, and it can also be decoupled from the rotating shaft 2 to release it. This configuration allows the rotating shaft 2 to switch between fixed and rotating states, making the steering wheel assembly 100 more convenient to use. Here, decoupling the locking element 410 from the rotating shaft 2 means that the relationship between the locking element 410 and the rotating shaft 2 changes from a coupled relationship to a relationship where there is no force interaction between them, such as a state of separation.

[0098] Because the locking element 410 and the rotating shaft 2 are detachably coupled, the above configuration allows the rotating shaft 2 to be locked at at least three different rotation angles, thereby fixing the steering wheel 3 in different positions. This means the steering wheel 3 can be locked at multiple rotation angles. It can be understood that in this case, the steering wheel 3 is fixed at least once during the rotation process. The rotation process here refers to the process from the start of the rotation of the steering wheel 3 to the end of the rotation. The rotation angle refers to the angle between the normal direction of the steering wheel 3 in its initial state and the normal direction after rotation. The rotation angle can be, but is not limited to, 0°, 5°, 10°, 45°, 90°, 120°, or 180°. A rotation angle of 0° means the steering wheel 3 has not yet rotated.

[0099] As an example, the rotating shaft 2 has three points at different positions along its circumference: point A, point B, and point C. Initially, the locking element 410 is coupled to point A of the rotating shaft 2, at which point the steering wheel 3's rotation angle is 0°, meaning the steering wheel 3 is locked in its initial position. Then, the locking element 410 decouples from the rotating shaft 2, and after the rotating shaft 2 rotates 30°, the locking element 410 is coupled to point B of the rotating shaft 2 again, at which point the steering wheel 3's rotation angle is 30°, meaning the steering wheel 3 is locked during the rotation process. The locking element 410 decouples from the rotating shaft 2 again, and continues to couple to point C of the rotating shaft 2, at which point the steering wheel 3's rotation angle is 90°, the steering wheel 3 is in its extreme rotation position, and the steering wheel assembly 100 is in a folded state, meaning the steering wheel 3 is locked in its extreme rotation position. Points A and C represent the first and second extreme positions, respectively.

[0100] By increasing the number of points where the pivot 2 is coupled with the locking element 410 in the circumferential direction, the steering wheel 3 can be locked and fixed at more rotation angles.

[0101] In some embodiments, the locking member 410 is configured to be selectively and separably coupled to at least three positions of the steering wheel 3 in the direction of steering wheel 3 rotation to lock the steering wheel 3. Locking the steering wheel 3 by directly coupling the locking member 410 to the steering wheel 3 also locks the steering wheel assembly 20.

[0102] As an example, the locking element 410 includes a slide bar slidably mounted on the fixed base 1, and the slide bar is parallel and spaced apart from the rotating shaft 2; the steering wheel 3 includes a handwheel frame 310 and spokes 320 fixedly connected, and the spokes 320 are fixedly connected to the rotating shaft 2. The slide bar is positioned corresponding to the spokes 320, and the spokes 320 are provided with at least three grooves spaced apart around the rotating shaft 2. During sliding, the slide bar can selectively insert into one of the grooves, thereby preventing the steering wheel 3 from rotating.

[0103] The following explanation uses the example of the locking element 410 being separably coupled to the steering wheel assembly 20, and the locking element 410 being separably coupled to the rotating shaft 2.

[0104] In some implementations, please refer to Figures 12 to 16 The locking mechanism 4 also includes a drive unit 420, which is configured to drive the locking member 410 toward and couple with the steering wheel assembly 20 to lock the steering wheel assembly 20, and / or drive the locking member 410 away from and decouple from the steering wheel assembly 20 to release the steering wheel assembly 20.

[0105] Optionally, the drive unit 420 is configured to drive the locking member 410 close to and coupled to the rotating shaft 2 to lock the rotating shaft 2, and / or drive the locking member 410 away from and decoupled from the rotating shaft 2 to release the rotating shaft 2.

[0106] In some examples, the drive unit 420 can be used to drive the locking member 410 close to and coupled to the rotating shaft 2. In other examples, the drive unit 420 can be used to drive the locking member 410 and decouple it from the rotating shaft 2. In still other examples, the drive unit 420 can both drive the locking member 410 to couple with the rotating shaft 2 and drive the locking member 410 to decouple it from the rotating shaft 2.

[0107] By setting the drive device 420 to drive the locking member 410 to move, the locking member 410 can be coupled or decoupled from the steering wheel assembly 20, thereby making the steering wheel assembly 100 easier to operate.

[0108] The driving device 420 can drive the locking member 410 to move by electricity, by elastic force, or by magnetic force; no limitation is made here.

[0109] In some implementations, please refer to Figures 12 to 16 The drive unit 420 includes a first elastic member 421 and a limiting member 422 disposed on the fixed base 1. The limiting member 422 is movably disposed on the fixed base 1. The first elastic member 421 is configured to push the locking member 410 closer to the steering wheel assembly 20 by driving the limiting member 422.

[0110] Here, the first elastic element 421 acts as a power source to drive the locking element 410 to couple with the rotating shaft 2. The first elastic element 421 has a certain buffering capacity, which ensures sufficient fit tolerance when the locking element 410 is coupled with the rotating shaft 2, reducing the risk of the locking element 410 and the rotating shaft 2 jamming. In addition, the first elastic element 421 can always apply a thrust toward the locking element 410 to the limiting element 422, thereby keeping the limiting element 422 close to the locking element 410 and preventing the locking element 410 from moving away from the rotating shaft 2, thus limiting the locking element 410.

[0111] As an example, the first elastic element 421 and the limiting element 422 are disposed below the weight of the locking element 410. The limiting element 422 is slidably disposed on the fixed base 1. The first elastic element 421 is a compression spring. A portion of the limiting element 422 (e.g., the abutment 4222) is located between the compression spring and the locking element 410. The compression spring applies a pushing force to the limiting element 422 toward the locking element 410. The limiting element 422 slides toward the locking element 410 until it abuts the locking element 410. Under the action of the compression spring, the limiting element 422 continues to apply a pushing force to the locking element 410, so that the locking element 410 is coupled with the rotating shaft 2.

[0112] In other examples, the first elastic element 421 and the limiting element 422 may also be disposed on the side of the locking element 410, and the limiting element 422 may also be rotatably disposed on the fixed base 1, which is not limited here.

[0113] In some implementations, please refer to Figures 12 to 16 The drive device 420 also includes a first drive member 423 disposed on the fixed base 1. The first drive member 423 is connected to the limiting member 422 and is used to pull the limiting member 422 to move away from the locking member 410.

[0114] When it is necessary to release the rotating shaft 2, the first driving member 423 pulls the limiting member 422 back, causing the limiting member 422 to separate from the locking member 410, thereby releasing the position restriction of the locking member 410 by the limiting member 422. After the limiting is released, the locking member 410 can move away from the rotating shaft 2 under its own weight or the action of other driving members, thereby achieving decoupling.

[0115] As an example, the first drive element 423 is a motor, such as a lever motor.

[0116] In some implementations, please refer to Figures 12 to 16 The drive device 420 also includes a first gear 424, which is connected to the first drive member 423. The limiting member 422 includes a rack portion 4221, which meshes with the first gear 424.

[0117] By engaging the first gear 424 with the rack portion 4221 of the limiting member 422, a transmission connection is achieved between the first driving member 423 and the limiting member 422. Specifically, the first driving member 423 drives the first gear 424 to rotate, and the first gear 424 then drives the rack portion 4221 to move.

[0118] The rack portion 4221 is provided with at least one tooth, which engages with the teeth on the first gear 424. When the first driving member 423 is a motor, the first gear 424 is fixed on the output shaft of the motor.

[0119] In some implementations, please refer to Figures 12 to 16 The drive unit 420 also includes a mounting housing 425, which is fixedly mounted on the fixed base 1. The first gear 424 is disposed inside the mounting housing 425, and the rack portion 4221 is slidably mounted on the mounting housing 425.

[0120] The first gear 424 is placed inside the mounting housing 425, and the rack portion 4221 meshes with the first gear 424. The mounting housing 425 can reduce the amount of impurities falling into the contact position between the teeth, and can also be filled with lubricant to lubricate the rack portion 4221 and the first gear 424.

[0121] As an example, the mounting housing 425 is a box body, the first gear 424 is installed inside the box body, two clearance holes are opened on the box body, the first drive member 423 is fixed outside the box body, the output shaft of the first drive member 423 extends into the box body through one of the clearance holes and is fixedly connected to the first gear 424; the rack part 4221 of the limiting member 422 extends into the box body through the other clearance hole and moves back and forth relative to the box body.

[0122] In some implementations, please refer to Figures 12 to 16 The limiting member 422 also includes an abutment 4222 connected to the rack portion 4221. The abutment 4222 is located outside the mounting shell 425 and is used to abut the locking member 410. The first elastic member 421 is located between the abutment 4222 and the mounting shell 425.

[0123] Optionally, the rack portion 4221 and the abutment 4222 are integrally formed. Usually, the extending direction of the rack portion 4221 is different from the extending direction of the abutment 4222. For example, the limiting member 422 is L-shaped, and the extending direction of the rack portion 4221 is perpendicular to the extending direction of the abutment 4222.

[0124] Setting the limiting member 422 to include an abutment 4222 located outside the mounting housing 425 not only facilitates the setting of the first elastic member 421, but also facilitates abutting against the locking member 410.

[0125] As an example, the mounting housing 425 is provided with a fixing groove, one end of the first elastic member 421 is fixed in the fixing groove, and the other end of the first elastic member 421 is connected to the abutment 4222.

[0126] In some implementations, please refer to Figures 12 to 16 The drive unit 420 includes a third drive member 426, which is used to drive the locking member 410 to separate from the steering wheel assembly 20.

[0127] By setting the third drive element 426 to drive the locking element 410 to separate from the steering wheel assembly 20, the steering wheel assembly 20 is released, thereby improving the reliability of the decoupling between the locking element 410 and the steering wheel assembly 20.

[0128] In some implementations, please refer to Figures 12 to 16The third driving member 426 includes a second elastic member 4261. The second elastic member 4261 provides elastic force to the locking member 410 to drive the locking member 410 to separate from the steering wheel assembly 20. One end of the second elastic member 4261 is connected to the locking member 410, and the other end is connected to the fixed seat 1 or the steering wheel assembly 20. The arrangement of the second elastic member 4261 can achieve the separation of the locking member 410 from the steering wheel assembly 20 by elastic force, which is not only simple in structure but also reliable in performance. The second elastic member 4261 can be positioned in various ways. As an example, the second elastic member 4261 is located on the side of the locking member 410 away from the rotating shaft 2. One end of the second elastic member 4261 is connected to the locking member 410, and the other end of the second elastic member 4261 is connected to the fixed seat 1. The second elastic member 4261 is used to pull the locking member 410 toward the fixed seat 1. As another example, the second elastic member 4261 is located on the side of the locking member 410 away from the fixed base 1. One end of the second elastic member 4261 is connected to the locking member 410, and the other end of the second elastic member 4261 is connected to the rotating shaft 2, for example, sleeved on the rotating shaft 2. The second elastic member 4261 is used to push the locking member 410 toward the fixed base 1.

[0129] In some implementations, please refer to Figure 12 The second elastic element 4261 is an offset torsion spring, one end of which is connected to the locking element 410, and the other end is connected to the fixed seat 1. The offset torsion spring can use its elasticity to provide an offset force to the locking element 410 so that the locking element 410 moves away from the steering wheel assembly 20.

[0130] As an example, the third driving member 426 is an offset torsion spring, and the locking member 410 is rotatably mounted on the fixed base 1 via a rotating rod. One end of the torsion spring is inserted into the fixed base 1, and the other end is inserted into the locking member 410. At the same time, the offset torsion spring is sleeved on the rotating rod. When the locking member 410 rotates, the offset torsion spring drives the locking member 410 to reset.

[0131] In some embodiments, the third actuating element 426 includes a magnetic structure for providing magnetic force to the locking element 410 to drive the locking element 410 away from the steering wheel assembly 20. The magnetic structure allows for the separation of the locking element 410 from the steering wheel assembly 20 by magnetic force, which is not only simple in structure but also reliable in performance.

[0132] In some embodiments, the magnetic structure includes a first sub-component and a second sub-component, which are configured to attract each other magnetically. At least one of the first and second sub-components is a magnet or an electromagnet. As an example, both the first and second sub-components are magnets, or one of the first and second sub-components is a magnet and the other is a metal block, such as an iron block, that can be attracted to a magnet.

[0133] As one example, the first sub-component is a magnet disposed on the locking member 410, and the second sub-component is a magnet disposed on the fixing base 1. As another example, the locking member 410 is made of iron, and the entire locking member 410 is reused as the first sub-component, while the second sub-component is a magnet disposed on the fixing base 1. As yet another example, the first sub-component is a magnet disposed on the locking member 410, the fixing base 1 is made of iron, and the entire fixing base 1 is reused as the second sub-component.

[0134] As can be seen, the first sub-component can be an independent structural component mounted on the locking component 410, such as a magnet. Of course, the locking component 410 can also be used as the first sub-component depending on the material selection. The second sub-component can be an independent structural component mounted on the fixing base 1, such as a magnet. Of course, the fixing base 1 can also be used as the second sub-component depending on the material selection.

[0135] In some embodiments, the magnetic structure includes a first sub-component and a third sub-component, which are configured to repel each other by magnetic force. The first and third sub-components are magnets or electromagnets. The first sub-component is disposed on the locking member 410, and the third sub-component is disposed on the steering wheel assembly 20, such as on the pivot 2.

[0136] Of course, in other embodiments, the locking member 410 can also be separated from the rotating shaft 2 by relying on gravity.

[0137] In some implementations, please refer to Figures 12 to 16 The locking member 410 includes a toothed portion 411, which engages with the rotating shaft 2 to couple the locking member 410 with the rotating shaft 2.

[0138] The toothed part 411 is a component with teeth. The toothed part 411 can be a rack, gear, or gear ring. The locking member 410 is coupled to the rotating shaft 2 by meshing with the toothed part 411. This method is not only simple, but also improves the stability and reliability of locking.

[0139] In some implementations, please refer to Figures 12 to 16 The steering wheel assembly 100 also includes a second gear 5, which is fixed on the rotating shaft 2. The rotating shaft 2 is used to mesh with the toothed part 411 through the second gear 5.

[0140] The toothed part 411 is indirectly meshed with the rotating shaft 2 through the second gear 5. The meshing between the toothed part 411 and the second gear 5 is a tooth-to-tooth engagement. By increasing the number of teeth on the second gear 5, the number of coupling positions between the rotating shaft 2 and the locking member 410 in the circumferential direction can be indirectly increased, so that the steering wheel 3 can be locked and fixed at more rotation angles.

[0141] Of course, in other embodiments, teeth, such as splines, can be provided on the surface of the rotating shaft 2, and the toothed portion 411 can directly mesh with it to realize the locking member 410 and the rotating shaft 2 directly meshing and connecting.

[0142] In some implementations, please refer to Figure 15 and Figure 16 The tooth portion 411 is configured to extend in a circumferential arc along the second gear 5.

[0143] Since the locking member 410 is required to prevent the rotating shaft 2 from rotating when it meshes with the rotating shaft 2, the toothed part 411 is set to extend in an arc along the circumference of the second gear 5. This increases the number of teeth meshing between the toothed part 411 and the second gear 5, allowing the torque to be transmitted better and reducing the risk of deformation or damage to the toothed part 411 and the second gear 5.

[0144] As an example, the tooth portion 411 corresponds to 1 / 8 to 1 / 4 of the circumference of the second gear 5.

[0145] In some implementations, please refer to Figures 12 to 16 The locking member 410 also includes a connector 412 connected to the toothed portion 411, and the connector 412 is rotatably connected to the fixed base 1.

[0146] That is, the locking member 410 is rotatably mounted on the fixed base 1 via the connector 412. As an example, the connector 412 is integrally formed with the toothed part 411, and the connector 412 is provided with a rotating through hole through which the rotating rod mounted on the fixed base 1 passes.

[0147] In some implementations, please refer to Figure 15 and Figure 16 The working process of the steering wheel assembly 100 is as follows: the shaft 2 rotates, causing the steering wheel 3 to flip; keeping the first driving member 423 stopped, the first elastic member 421 pushes the limiting member 422 to abut against the locking member 410, the locking member 410 rotates, the toothed part 411 of the locking member 410 approaches the second gear 5 and meshes with the second gear 5, the shaft 2 stops rotating, and the steering wheel 3 is locked; then the first driving member 423 is activated, the first driving member 423 drives the first gear 424 to rotate, the first gear 424 drives the limiting member 422 to move back, the limiting member 422 squeezes the first elastic member 421 and separates from the locking member 410, and the locking member 410, under the action of the third driving member 426, causes the toothed part 411 to separate from the second gear 5, the shaft 2 is released and continues to move, and the steering wheel 3 continues to flip.

[0148] In some implementations, please refer to Figures 12 to 16 The steering wheel assembly 100 also includes a first protective cover 61, which is disposed on the fixed base 1 and covers at least part of the locking mechanism 4.

[0149] By enclosing at least part of the locking mechanism 4 within the first protective cover 61, at least part of the locking mechanism 4 can be protected, preventing dust from entering and lubricating oil from seeping out, thereby improving the transmission effect and service life of the locking mechanism 4.

[0150] As an example, the first protective cover 61 encloses at least a portion of the locking member 410, at least a portion of the first elastic member 421, at least a portion of the limiting member 422, at least a portion of the first gear 424, and at least a portion of the third driving member 426. The first protective cover 61 also encloses the second gear 5.

[0151] In some implementations, please refer to Figures 17 to 19 The steering wheel assembly 100 also includes a drive mechanism 7, which is mounted on the fixed base 1 and drivenly connected to the steering wheel assembly 20. The drive mechanism 7 is used to drive the steering wheel assembly 20 to rotate relative to the fixed base 1. By setting the drive mechanism 7 to drive the steering wheel assembly 20, the steering wheel assembly 100 can be made more automated.

[0152] In some embodiments, the drive mechanism 7 includes a second drive member 710 disposed on the fixed base 1, and the second drive member 710 is drivenly connected to the rotating shaft 2.

[0153] By setting a second driving component 710 to drive the rotating shaft 2 to rotate, the steering wheel 3 can be automatically flipped.

[0154] As an example, the second drive element 710 is an electric drive element, such as a motor.

[0155] In some implementations, please refer to Figures 17 to 19 The drive mechanism 7 also includes a transmission structure 720 disposed on the fixed base 1, which is connected between the second drive member 710 and the rotating shaft 2.

[0156] The second driving member 710 drives the rotating shaft 2 to rotate via the transmission structure 720. Of course, in other embodiments, the second driving member 710 can also directly drive the rotating shaft 2. The transmission form of the transmission structure 720 is not limited here; for example, it can be a gear transmission or a belt transmission.

[0157] In some implementations, please refer to Figures 17 to 19 The transmission structure 720 includes a worm gear 721 and a gear set 722 that are connected in transmission. The worm gear 721 is connected in transmission to the second driving member 710, and the gear set 722 is connected in transmission to the rotating shaft 2.

[0158] With the above configuration, the second driving component 710 drives the worm gear 721 to rotate, the worm gear 721 drives the gear set 722 to rotate, and finally the gear set 722 drives the rotating shaft 2 to rotate.

[0159] In some implementations, please refer to Figures 17 to 19 The worm gear 721 includes a first-stage worm 7211, a first-stage worm wheel 7212, a drive shaft 7213, a second-stage worm 7214, and a second-stage worm wheel 7215. The first-stage worm 7211 is connected to the second drive member 710, and the first-stage worm 7211 meshes with the first-stage worm wheel 7212. The first-stage worm wheel 7212 and the second-stage worm 7214 are fixedly mounted on the drive shaft 7213, and the second-stage worm 7214 meshes with the second-stage worm wheel 7215. The gear set 722 includes a meshing third gear 7221 and a fourth gear 7222, and the third gear 7221 is coaxially driven with the second-stage worm wheel 7215. The fourth gear 7222 is splinedly connected to the rotating shaft 2.

[0160] Specifically, the second driving component 710 drives the first-stage worm gear 7211 to rotate, the first-stage worm gear 7211 drives the first-stage worm wheel 7212 to rotate, the first-stage worm wheel 7212 drives the transmission shaft 7213 and the second-stage worm gear 7214 to rotate synchronously, the second-stage worm gear 7214 drives the second-stage worm wheel 7215 to rotate, the second-stage worm wheel 7215 rotates synchronously with the third gear 7221, the third gear 7221 drives the fourth gear 7222 to rotate, and the fourth gear 7222 drives the rotating shaft 2 to rotate, thereby completing the second driving component 710 driving the rotating shaft 2 to rotate.

[0161] In some embodiments, the steering wheel assembly 100 operates as follows: the first drive member 423 pulls back the limiting member 422, releasing the locking member 410 from locking the shaft 2; then the second drive member 710 is activated, causing the drive transmission structure 720 to rotate the shaft 2, thus rotating the steering wheel 3. After the steering wheel 3 is rotated to a specified angle position, the first drive member 423 and the second drive member 710 stop working, the shaft 2 stops rotating, and the limiting member 422, through the first elastic member 421, pushes the toothed portion 411 of the locking member 410 to mesh with the second gear 5 on the shaft 2 to achieve the locking function, thus fixing the steering wheel 3 at the specified angle position.

[0162] In some implementations, please refer to Figures 17 to 19 The steering wheel assembly 100 also includes a second protective cover 62, which is disposed on the mounting base 1 and covers at least part of the drive mechanism 7.

[0163] By enclosing at least part of the drive mechanism 7 within the second protective cover 62, at least part of the drive mechanism 7 can be protected, preventing dust from entering and lubricating oil from leaking out, thereby improving the transmission effect and service life of the drive mechanism 7.

[0164] As an example, the second protective cover 62 encloses at least part of the transmission structure 720.

[0165] In some implementations, please refer to Figures 12 to 19The drive mechanism 7 and the locking mechanism 4 are spaced apart on the fixed base 1. By spaced apart, the drive mechanism 7 and the locking mechanism 4 on the fixed base 1 reduce mutual interference. The drive mechanism 7 and the locking mechanism 4 are compactly designed, occupy little space, and have high structural strength. As an example, the fixed base 1 includes a body 110 and a support portion 120. The body 110 has a first side surface and a second side surface facing away from each other in the thickness direction. The support portion 120 protrudes from the first side surface, and the drive mechanism 7 and the locking mechanism 4 are also disposed on the first side surface, but the drive mechanism 7 and the locking mechanism 4 are located on opposite sides of the support portion 120.

[0166] In some implementations, please refer to Figures 1 to 11 The steering wheel 3 includes a connected handwheel frame 310 and spokes 320, with the spokes 320 fixedly connected to the pivot 2.

[0167] The steering wheel 3 includes a handwheel frame 310 and spokes 320. The handwheel frame 310 is for hand gripping, and the spokes 320 are for fixed connection with the pivot 2.

[0168] The handwheel frame 310 is annular, but can be circular or non-circular; no limitation is made here. There are two spokes 320, which are arranged opposite each other on the handwheel frame 310. Typically, the spokes 320 and the handwheel frame 310 are not on the same plane; the spokes 320 extend along the inner side of the handwheel frame 310 in a direction away from the handwheel frame 310. The free ends of the spokes 320 are fixedly connected to the shaft 2. The spokes 320 and the shaft 2 can be welded together or connected via a connector.

[0169] In some implementations, please refer to Figures 9 to 11 The steering wheel assembly 100 includes a first connector 81. Along the axial direction of the first connector 81, the first connector 81 includes a first connecting segment 811 and a second connecting segment 812 connected in sequence. The circumferential contours of the first connecting segment 811 and the second connecting segment 812 are both non-circular. A first mounting hole 330 is provided on the spoke 320, and a second mounting hole 210 is provided on the pivot 2. The first connecting segment 811 extends into the first mounting hole 330 and is adapted to the first mounting hole 330, and the second connecting segment 812 extends into the second mounting hole 210 and is adapted to the second mounting hole 210.

[0170] The circumferential contours of both the first connecting segment 811 and the second connecting segment 812 are non-circular, and can be, for example, elliptical, D-shaped, or polygonal. The circumferential contours of the first connecting segment 811 and the second connecting segment 812 can be the same or different. The first connecting segment 811 is adapted to the first mounting hole 330, so the first mounting hole 330 is also non-circular; similarly, the second connecting segment 812 is adapted to the second mounting hole 210, so the second mounting hole 210 is also non-circular.

[0171] Since both the spokes 320 and the pivot 2 are engaged with the first connector 81, and the circumferential profile of the first connector 81 is non-circular, the pivot 2 can effectively transmit torque to the spokes 320 through the first connector 81, thereby driving the steering wheel 3 to rotate.

[0172] In some implementations, please refer to Figure 10 The circumferential profile of the first connecting segment 811 is a polygon, and the circumferential profile of the second connecting segment 812 is also a polygon. Correspondingly, the outer circumferential surfaces of the first connecting segment 811 and the second connecting segment 812 each include multiple planes, which can transmit torque more effectively. As an example, the circumferential profiles of the first connecting segment 811 and the second connecting segment 812 are each independently quadrilateral, pentagonal, or hexagonal.

[0173] In some implementations, please refer to Figure 10 and Figure 11 The radial dimension of the first connecting segment 811 is larger than that of the second connecting segment 812. The first connecting segment 811 is used to connect with the spoke 320, and the second connecting segment 812 is used to connect with the shaft 2. During the connection process, the second connecting segment 812 with the smaller radial dimension on the first connecting member 81 is passed through the first mounting hole 330 and the second mounting hole 210 in sequence. Finally, the first connecting segment 811 mates with the first mounting hole 330, and the second connecting segment 812 mates with the second mounting hole 210, reducing the assembly difficulty. In addition, increasing the radial dimension of the first connecting segment 811 can enhance the strength of the first connecting segment 811 and improve the reliability of the connection.

[0174] In some implementations, please refer to Figure 10 and Figure 11 Along the direction from the first connecting section 811 to the second connecting section 812, the radial dimension of the first connecting section 811 gradually decreases, and the radial dimension of the second connecting section 812 also gradually decreases. That is to say, along the assembly direction, both the first connecting section 811 and the second connecting section 812 have a taper, which can guide the first connecting part 81 to quickly engage with the spokes 320 and the pivot 2, further reducing the assembly difficulty.

[0175] In some implementations, please refer to Figure 9 and Figure 11 The steering wheel assembly 100 also includes a second connector 82, which secures the spokes 320, the pivot 2, and the first connector 81 together. This further enhances the stability of the connection between the spokes 320 and the pivot 2. Optionally, the second connector 82 is a threaded fastener, such as a screw or bolt.

[0176] In some implementations, please refer to Figure 1 and Figure 7The spoke 320 is also provided with a third mounting hole 340, through which at least one of the button 14 and the paddle 15 can be mounted on the spoke 320.

[0177] In some implementations, please refer to Figures 6 to 8 The mounting base 1 includes a body 110 and a support portion 120. The support portion 120 protrudes from one side surface of the body 110, and the rotating shaft 2 is rotatably mounted on the support portion 120. Using the support portion 120 to support and assemble the rotating shaft 2 reduces installation difficulty. Optionally, the rotating shaft 2 is connected to the support portion 120 via a bearing 16, thereby reducing wear on the rotating shaft 2. As an example, there are two support portions 120, spaced apart on the first side surface of the body 110, to provide stable support for the rotating shaft 2.

[0178] In some implementations, please refer to Figures 1 to 6 The steering wheel assembly 100 also includes an airbag 9, which is mounted on the body 110, with the airbag 9 and the pivot 2 located on opposite sides of the body 110. The body 110 has a first side surface and a second side surface facing away from each other. The pivot 2 is mounted on the first side surface, and the locking mechanism 4 and the drive mechanism 7 that cooperate with the pivot 2 are also mounted on the first side surface. The airbag 9 is mounted on the second side surface facing away from each other. The second side surface provides more assembly space for the airbag 9, reducing assembly difficulty. In addition, the steering wheel 3 can be locked at multiple flip angles, thereby providing effective support for the deployment of the airbag 9 during the folding of the steering wheel assembly 100 and providing safety protection for the driver.

[0179] In some implementations, please refer to Figures 3 to 6The steering wheel assembly 100 also includes an airbag 9 and a switch assembly 10. The switch assembly 10 includes a bracket 1010 that is liftably mounted on a fixed base 1 and a switch 1030 that is fixedly mounted on the fixed base 1. The bracket 1010 has a trigger part 1020 for triggering the switch 1030 when the bracket 1010 is close to the fixed base 1. The airbag 9 is mounted on the bracket 1010, and the bracket 1010 is located between the fixed base 1 and the airbag 9. Thus, by pressing the airbag 9, the trigger part 1020 in the switch assembly 10 can trigger the switch 1030, making the structure of the steering wheel assembly 100 more compact. As an example, the switch 1030 can be used to connect to a horn, so that pressing the airbag 9 can realize the horn function. The bracket 1010 is floatingly mounted on the second side surface of the body 110. Specifically, multiple guide posts are erected on the second side surface, and the bracket 1010 has guide holes through which the guide posts pass. A return spring is provided between the bracket 1010 and the body 110. When the airbag 9 is pressed, the airbag 9 moves the support 1010 downward, compressing the return spring. The trigger part 1020 on the back of the support 1010 comes into contact with or approaches the switch 1030 on the second side surface, thereby triggering the switch 1030 to conduct. After the press on the airbag 9 is released, the support 1010 drives the airbag 9 to return to its original position via the return spring. Optionally, the switch 1030 is a micro switch, and the trigger part 1020 is a protrusion that triggers the micro switch by squeezing it. Optionally, the switch 1030 is a reed switch, and the trigger part 1020 is a magnet that triggers the reed switch to conduct when it approaches the reed switch.

[0180] In some implementations, please refer to Figures 20 to 23 The steering wheel assembly 100 also includes a steering column 11, which is connected to a mounting base 1. The extension direction of the steering column 11 intersects the extension direction of the pivot 2. With the steering column 11 connected to the mounting base 1, the torque of the steering wheel 3 can be transmitted to the steering column 11 through the mounting base 1, thereby enabling steering control. The extension direction of the steering column 11 intersects the extension direction of the pivot 2, for example, they are perpendicular to each other. Rotation of the pivot 2 causes the steering wheel 3 to rotate in directions closer to and further away from the steering column 11. When the steering wheel 3 is close to the steering column 11, the steering wheel assembly 100 enters a folded state, allowing the steering wheel 3 to be stored and releasing its storage space; when the steering wheel 3 is away from the steering column 11, the steering wheel assembly 100 enters an unfolded state, allowing normal operation of the steering wheel 3. As an example, one end of the steering column 11 has an external spline on its outer surface, and the body 110 has a connecting through hole with an internal spline. The steering column 11 engages with the internal spline on the body 110 through the external spline.

[0181] In some implementations, please refer to Figure 22 and Figure 23The steering wheel assembly 100 also includes a clock spring 12 mounted on the steering column 11, with a first protrusion 1210 and a second protrusion 1220. The steering wheel assembly 100 also includes a first protective cover 61 and a second protective cover 62. A first cylinder 611 is mounted on the first protective cover 61 and fits around the first protrusion 1210. A second cylinder 621 is mounted on the second protective cover 62 and fits around the second protrusion 1220. Thus, turning the steering wheel 3 will cause the clock spring 12 to rotate.

[0182] Secondly, please see Figures 24 to 30 This application provides a vehicle 200, which includes a vehicle body 2010 and the aforementioned steering wheel assembly 100 disposed on the vehicle body 2010.

[0183] The vehicle 200 includes the aforementioned steering wheel assembly 100, and therefore has all the beneficial effects of the aforementioned steering wheel assembly 100, which will not be elaborated here.

[0184] The vehicle 200 can be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this application does not make any specific restrictions on it.

[0185] In some implementations, please refer to Figure 30 In the case where the steering wheel assembly 100 includes a second drive member 710 and the second drive member 710 is electrically driven, and the steering wheel assembly 20 includes a pivot 2 and a steering wheel 3, the vehicle 200 also includes a controller 2020, which is electrically connected to the second drive member 710, and the controller 2020 is configured to:

[0186] The system controls the second driving component 710 to drive the rotating shaft 2 to rotate in a first clockwise direction and acquire the current of the second driving component 710; based on the fact that the current of the second driving component 710 is greater than or equal to a first preset current value, the system controls the second driving component 710 to drive the rotating shaft 2 to rotate in a second clockwise direction by a preset angle and acquire the current of the second driving component 710 again, the second clockwise direction being the opposite of the first clockwise direction; based on the fact that the current of the second driving component 710 acquired again is greater than or equal to the first preset current value, the system controls the second driving component 710 to stop working; based on the fact that the current of the second driving component 710 acquired again is less than the first preset current value, the system controls the second driving component 710 to drive the rotating shaft 2 to rotate in the first clockwise direction again.

[0187] Here, the first hourly direction can be either clockwise or counterclockwise, and the second hourly direction is the opposite of the first hourly direction. When the first hourly direction is clockwise, the second hourly direction is counterclockwise.

[0188] The second drive unit 710 drives the rotating shaft 2 to rotate, for example, clockwise, which will cause the steering wheel 3 to flip, for example, downward. The current of the second drive unit 710 is used to determine whether the steering wheel 3 interferes with or traps the driver during the flipping process.

[0189] If the current of the second drive unit 710 is less than the first preset current value, it is considered that no interference or clamping has occurred, and there is no need to trigger the anti-pinch function. The second drive unit 710 keeps the drive shaft 2 rotating in the forward direction.

[0190] If the current of the second drive component 710 is greater than or equal to the first preset current value, interference or clamping is determined to have occurred, requiring the anti-pinch function to be triggered. In this case, the second drive component 710 is controlled to drive the rotating shaft 2 in reverse, causing the steering wheel 3 to rotate upwards by a certain angle, such as 10°. The current of the second drive component 710 is then measured again. If the current is still greater than or equal to the first preset current value, it indicates that reversing the rotating shaft 2 has not improved the problem, and for safety reasons, the second drive component 710 is controlled to stop working. If the current of the second drive component 710 measured again is less than the first preset current value, the second drive component 710 is controlled to drive the rotating shaft 2 to rotate forward again.

[0191] The above solution can achieve the anti-pinch function and improve safety.

[0192] In some embodiments, before controlling the second drive member 710 to drive the rotating shaft 2 to rotate in the first clockwise direction, it is also necessary to confirm whether the steering wheel 3 is returned to center; in response to the steering wheel 3 returning to center, the second drive member 710 is controlled to drive the rotating shaft 2 to rotate in the first clockwise direction and the current of the second drive member 710 is obtained.

[0193] In some implementations, please refer to Figures 24 to 26 and Figure 30 The vehicle 200 also includes an electric telescopic device 2030, which is mounted on the vehicle body 2010. A steering wheel assembly 100 is mounted on the electric telescopic device 2030, which is used to drive the steering wheel assembly 100 to telescopically move relative to the vehicle body 2010. A controller 2020 is electrically connected to the electric telescopic device 2030, and the controller 2020 is further configured to:

[0194] The electric telescopic device 2030 is controlled to move the steering wheel assembly 100 toward the vehicle body 2010 and acquire current from the electric telescopic device 2030. Based on the current of the electric telescopic device 2030 being greater than or equal to a second preset current value, the electric telescopic device 2030 is controlled to move the steering wheel assembly 100 a preset distance away from the vehicle body 2010 and acquire current from the electric telescopic device 2030 again. Based on the current of the electric telescopic device 2030 being acquired again being greater than or equal to the second preset current value, the electric telescopic device 2030 is controlled to stop working. Based on the current of the electric telescopic device 2030 being acquired again being less than the second preset current value, the electric telescopic device 2030 is controlled to move the steering wheel assembly 100 toward the vehicle body 2010 again.

[0195] The electric telescopic device 2030 moves the steering wheel assembly 100 closer to the vehicle body 2010, causing the steering wheel assembly 100 to descend and the distance between the steering wheel assembly 100 and the vehicle body 2010 to decrease. The current of the electric telescopic device 2030 is measured to determine whether the steering wheel assembly 100 interferes with or traps the driver during its descent.

[0196] If the current of the electric telescopic device 2030 is less than the second preset current value, it is considered that no interference or clamping has occurred, and there is no need to trigger the anti-pinch function. The electric telescopic device 2030 drives the steering wheel assembly 100 to continue to descend.

[0197] If the current of the electric telescopic device 2030 is greater than or equal to the second preset current value, interference or clamping is determined to have occurred, and the anti-pinch function needs to be triggered. At this time, the electric telescopic device 2030 is controlled to raise the steering wheel assembly 100 a certain distance, for example, 20mm. The current of the electric telescopic device 2030 is measured again. If the current is still greater than or equal to the second preset current value, it means that raising the steering wheel assembly 100 has not improved the problem. For safety reasons, the electric telescopic device 2030 is controlled to stop working. If the current of the electric telescopic device 2030 measured again is less than the second preset current value, the electric telescopic device 2030 is controlled to lower the steering wheel assembly 100 again.

[0198] The above solution can achieve the anti-pinch function and improve safety.

[0199] Optionally, the electric telescopic device 2030 includes a guide rail and a third drive member. The steering wheel assembly 100, more specifically the steering column 11, is movably mounted on the guide rail. The third drive member drives the steering wheel assembly 100 to move along the guide rail. The guide rail is fixed to the vehicle body 2010 (e.g., the dashboard). During the movement, the steering wheel assembly 100 moves up and down relative to the vehicle body 2010. In one example, the electric telescopic device 2030 is an electric telescopic column.

[0200] When the steering wheel assembly 100 is lowered, it can be stored; when the steering wheel assembly 100 is raised, it can be operated to control the steering of the vehicle 200.

[0201] As an example, the folding process of the steering wheel assembly 100 includes: the steering wheel 3 is first flipped and folded by the pivot 2, and then the entire steering wheel assembly 100 is moved and retracted towards the vehicle body 2010 by the electric telescopic device 2030.

[0202] As another example, the folding process of the steering wheel assembly 100 includes: first, moving and retracting the entire steering wheel assembly 100 toward the vehicle body 2010 via the electric telescopic device 2030; then, folding the steering wheel 3 by flipping it over via the pivot 2.

[0203] In some embodiments, before controlling the electric telescopic device 2030 to move the steering wheel assembly 100 toward the vehicle body 2010, it is necessary to confirm whether the steering wheel 3 has been rotated: in response to the steering wheel 3 being rotated, the electric telescopic device 2030 is controlled to move the steering wheel assembly 100 toward the vehicle body 2010 and the current of the electric telescopic device 2030 is obtained.
