[0041] 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.

[0042] According to the first aspect of this application, see Figures 1 to 7 This application provides a tubular assembly.

[0043] See Figure 1 The column assembly includes a drive unit 1, a connecting shaft 2, a switching component 3, a height adjustment component 4, an angle adjustment component 5, and a tactile simulation component 6;

[0044] Connecting shaft 2 is used to connect the steering wheel;

[0045] The switching component 3 can switch between multiple modes, which include at least a first mode, a second mode, and a third mode;

[0046] In the first mode, the switching component 3 connects the drive component 1 and the height adjustment component 4 to drive the height adjustment component 4 to move the connecting shaft 2 along the axial direction of the connecting shaft 2.

[0047] In the second mode, the switching component 3 connects the drive component 1 and the angle adjustment component 5, so that the angle adjustment component 5 drives the connecting shaft 2 to deflect radially along the connecting shaft 2;

[0048] In the third mode, the switching component 3 connects the drive component 1 and the tactile simulation component 6 to drive the tactile simulation component 6 to apply tactile damping to the connecting shaft 2.

[0049] Understandably, when steering wheel height adjustment is required, switching component 3 is in the first mode. In this mode, switching component 3 connects drive component 1 and height adjustment component 4, allowing drive component 1 to drive height adjustment component 4 to move connecting shaft 2 axially. Since connecting shaft 2 is connected to the steering wheel, the steering wheel moves axially accordingly, thus achieving steering wheel height adjustment. When steering wheel angle adjustment is required, switching component 3 is in the second mode. In this mode, switching component 3 connects drive component 1 and angle adjustment component 5, allowing drive component 1 to drive angle adjustment component 5 to rotate connecting shaft 2 radially. Since connecting shaft 2 is connected to the steering wheel, the steering wheel rotates radially accordingly, thus achieving steering wheel angle adjustment. When hand feel simulation is required, switching component 3 is in the third mode. In this mode, switching component 3 connects drive component 1 and hand feel simulation component 6, allowing drive component 1 to drive hand feel simulation component 6 to apply hand feel damping to connecting shaft 2. Since the steering wheel is connected to connecting shaft 2, hand feel simulation is achieved. In other words, this application can achieve hand feel simulation, steering wheel angle adjustment and steering wheel height adjustment through a single drive component 1, which is beneficial to improve the integration of the column assembly and reduce the cost and weight of the column assembly.

[0050] Understandably, in the third mode, drive component 1 can output torque to connecting shaft 2, which is connected to the steering wheel, thus simulating steering feel. By controlling the output torque of drive component 1, different levels of steering feel simulation can be achieved.

[0051] Understandably, the tubing assembly in related technologies requires at least two motors to achieve the three functions of tactile feedback simulation, angle adjustment, and height adjustment. However, this application only requires one drive unit 1 to achieve all three functions, effectively improving the integration of the tubing assembly.

[0052] In some examples, the drive element 1 is, for example, a motor or a rotary cylinder or any other suitable drive component.

[0053] In some embodiments, see Figure 2 The switching component 3 includes a moving part 31 and a switching transmission part 32. The moving part 31 is connected to the switching transmission part 32, and the moving part 31 is used to drive the switching transmission part 32 to move.

[0054] In the first mode, the transmission component 32 is switched to drive the drive component 1 and the height adjustment component 4; in the second mode, the transmission component 32 is switched to drive the drive component 1 and the angle adjustment component 5; and in the third mode, the transmission component 32 is switched to drive the drive component 1 and the hand feel simulation component 6.

[0055] Understandably, the moving part 31 can drive the switching transmission part 32 to move, allowing the switching transmission part 32 to move to different positions, thereby enabling the switching component 3 to switch between the first mode, the second mode, and the third mode. When the switching component 3 is in the first mode, the switching transmission part 32 drives the drive part 1 and the height adjustment component 4 to adjust the height of the steering wheel. When the switching component 3 is in the second mode, the switching transmission part 32 drives the drive part 1 and the angle adjustment component 5 to adjust the angle of the steering wheel. When the switching component 3 is in the third mode, the switching transmission part 32 drives the drive part 1 and the feel simulation component 6 to simulate the feel of the steering wheel.

[0056] In some embodiments, see Figure 2 The switching transmission component 32 includes a first gear 321, a second gear 322, and a third gear 323, all of which are connected to the moving component 31.

[0057] In the first mode, the first gear 321 drives the drive unit 1 and the height adjustment component 4; in the second mode, the second gear 322 drives the drive unit 1 and the angle adjustment component 5; and in the third mode, the third gear 323 drives the drive unit 1 and the hand feel simulation component 6.

[0058] Understandably, the movable component 31 can drive the first gear 321, the second gear 322, and the third gear 323 to move, allowing the switching component 3 to switch between the first mode, the second mode, and the third mode. When the switching component 3 is in the first mode, the first gear 321 drives the drive component 1 and the height adjustment component 4, and the drive component 1 can drive the height adjustment component 4 through the first gear 321 to adjust the height of the steering wheel. When the switching component 3 is in the second mode, the second gear 322 drives the drive component 1 and the angle adjustment component 5, and the drive component 1 can drive the angle adjustment component 5 through the second gear 322 to adjust the angle of the steering wheel. When the switching component 3 is in the third mode, the third gear 323 drives the drive component 1 and the hand feel simulation component 6, and the drive component 1 can drive the hand feel simulation component 6 through the third gear 323 to simulate the hand feel.

[0059] In some embodiments, see Figure 2The switching assembly 3 also includes a switching shaft 33, and the moving part 31 includes a first electromagnet 311 and a second electromagnet 312. The switching transmission part 32 is connected to the switching shaft 33. The first electromagnet 311 and the second electromagnet 312 are located on both sides of the switching transmission part 32. The first electromagnet 311 is used to drive the switching shaft 33 to move in a first direction, and the second electromagnet 312 is used to drive the switching shaft 33 to move in a second direction. The first direction and the second direction are opposite.

[0060] It is understandable that the first electromagnet 311 can drive the switching shaft 33 to move in the first direction, and the second electromagnet 312 can drive the switching shaft 33 to move in the second direction. Since the switching transmission component 32 is connected to the switching shaft 33, the switching transmission component 32 can be controlled to move in the first or second direction, thereby adjusting the position of the switching transmission component 32 and enabling the switching component 3 to switch between the first mode, the second mode and the third mode.

[0061] In some examples, when the first electromagnet 311 is energized, it can drive the switching shaft 33 to move in the first direction, at which time the second electromagnet 312 may not be energized. When the second electromagnet 312 is energized, it can drive the switching shaft 33 to move in the second direction, at which time the second electromagnet 312 may not be energized.

[0062] In some embodiments, see Figure 2 The switching component 3 also includes a first reset component 34 and a second reset component 35. The first reset component 34 is connected to the first electromagnet 311 and the switching transmission component 32, and the second reset component 35 is connected to the second electromagnet 312 and the switching transmission component 32.

[0063] The first reset member 34 is used to drive the switching transmission member 32 to reset after the first electromagnet 311 is de-energized, and the second reset member 35 is used to drive the switching transmission member 32 to reset after the second electromagnet 312 is de-energized.

[0064] Understandably, when the first electromagnet 311 is energized, it drives the switching shaft 33 and the switching transmission component 32 to move in the first direction. After the first electromagnet 311 is de-energized, it no longer applies a force in the first direction to the switching shaft 33. At this time, the first reset component 34 can reset the switching shaft 33 and the switching transmission component 32. Similarly, when the second electromagnet 312 is energized, it drives the switching shaft 33 and the switching transmission component 32 to move in the second direction. After the second electromagnet 312 is de-energized, it no longer applies a force in the second direction to the switching shaft 33. At this time, the second reset component 35 can reset the switching shaft 33 and the switching transmission component 32.

[0065] In some examples, the first reset element 34 and the second reset element 35 are, for example, springs or elastic blocks. When the first electromagnet is energized, the first electromagnet 311 drives the switching shaft 33 and the switching transmission element 32 to move in the first direction, causing the first reset element 34 to deform. When the first electromagnet 311 is de-energized, the first reset element 34 will return to its original shape and drive the switching shaft 33 and the switching transmission element 32 to reset. When the second electromagnet is energized, the second electromagnet 312 drives the switching shaft 33 and the switching transmission element 32 to move in the second direction, causing the second reset element 35 to deform. When the second electromagnet 312 is de-energized, the second reset element 35 will return to its original shape and drive the switching shaft 33 and the switching transmission element 32 to reset.

[0066] In some embodiments, see Figure 3 The height adjustment assembly 4 includes a height adjustment transmission component 41, a height adjustment lead screw 42, and a height adjustment nut 43. The height adjustment transmission component 41 is connected to the height adjustment lead screw 42, the height adjustment nut 43 is connected to the height adjustment lead screw 42, and the height adjustment nut 43 is connected to the connecting shaft 2.

[0067] In the first mode, the switching component 3 is connected to the drive component 1 and the height adjustment drive component 41.

[0068] It is understandable that when the switching component 3 is in the first mode, the drive component 1 is connected to the height adjustment transmission component 41. The drive component 1 can drive the height adjustment screw 42 to rotate through the height adjustment transmission component 41, so that the height adjustment nut 43 moves along the height adjustment screw 42, thereby causing the connecting shaft 2 to move axially, thus realizing the height adjustment of the steering wheel.

[0069] In some examples, the height adjustment transmission 41 is, for example, a gear or a gear set.

[0070] In some embodiments, see Figure 4 The angle adjustment assembly 5 includes an angle adjustment transmission component 51, an angle adjustment screw 52, ​​an angle adjustment nut 53, and an adjustment bracket 54. The angle adjustment transmission component 51 is connected to the angle adjustment screw 52, ​​the angle adjustment nut 53 is connected to the angle adjustment screw 52, ​​the adjustment bracket 54 is connected to the angle adjustment nut 53, and the connecting shaft 2 is connected to the adjustment bracket 54.

[0071] In the second mode, the switching component 3 connects the transmission angle adjustment transmission component 51 and the drive component 1.

[0072] It is understandable that when the switching component 3 is in the second mode, the switching component 3 drives the angle adjustment transmission component 51 and the drive component 1. The drive component 1 can drive the angle adjustment screw 52 to rotate through the angle adjustment transmission component 51, so that the angle adjustment nut 53 moves along the angle adjustment screw 52. Under the action of the angle adjustment nut 53, the adjustment bracket 54 deflects along the radial direction of the angle adjustment screw 52, ​​thereby driving the connecting shaft 2 to deflect, so as to realize the angle adjustment of the steering wheel.

[0073] In some examples, the adjusting bracket 54 can be directly connected to the connecting shaft 2. The adjusting bracket 54 can also be indirectly connected to the connecting shaft 2, that is, there are other components between the adjusting bracket 54 and the connecting shaft 2.

[0074] In some examples, the angle adjustment transmission 51 is, for example, a gear or a gear set.

[0075] In some embodiments, see Figure 3 The tactile simulation component 6 includes a rotating component 61, which is connected to the connecting shaft 2 and is used to drive the connecting shaft 2 to rotate.

[0076] In the third mode, the switching component 3 drives the rotating component 61 and the driving component 1.

[0077] It is understandable that when the switching component 3 is in the third mode, the switching component 3 drives the rotating component 61 and the driving component 1. The driving component 1 can drive the rotating component 61 to rotate, so that the rotating component 61 can drive the connecting shaft 2 to rotate, thereby realizing the torque output of the driving component 1 to the steering wheel and realizing the hand feel simulation.

[0078] In some examples, the rotating component 61 can be directly connected to the connecting shaft 2. The rotating component 61 can also be indirectly connected to the connecting shaft 2, i.e., there are other components between the adjusting bracket 54 and the connecting shaft 2.

[0079] In some examples, the rotating element 61 is, for example, a gear or a gear set.

[0080] In some embodiments, see Figure 1 The tubular assembly also includes an outer tube 7 and an inner tube 8. The outer tube 7 is sleeved outside the inner tube 8, and the inner tube 8 can rotate relative to the outer tube 7. The height adjustment component 4 is connected to the inner tube 8.

[0081] The angle adjustment component 5 is connected to the outer column 7, and the angle adjustment component 5 is used to drive the outer column 7 to deflect radially along the connecting shaft 2;

[0082] The tactile simulation component 6 is connected to the inner cylinder 8, and the tactile simulation component 6 is used to drive the inner cylinder 8 to rotate.

[0083] It is understood that the height adjustment component 4 is connected to the connecting shaft 2, and the height adjustment component 4 can drive the connecting shaft 2 to move axially to achieve steering wheel height adjustment. The angle adjustment component 5 can drive the outer pillar 7 to deflect radially along the connecting shaft 2. The outer pillar 7 can drive the inner pillar 8 and the height adjustment component 4 to deflect synchronously, causing the connecting shaft 2 to deflect as well, thereby achieving steering wheel angle adjustment. The feel simulation component 6 can drive the inner pillar 8 to rotate, and the inner pillar 8 can drive the height adjustment component 4 to rotate synchronously, causing the connecting shaft 2 to rotate as well. This allows the torque of the drive component 1 to be output to the steering wheel, applying feel damping to the steering wheel to achieve feel simulation. In other words, this embodiment connects the height adjustment component 4, the angle adjustment component 5, and the feel simulation component 6 together, which is beneficial to improving the integration of the pillar assembly.

[0084] In some examples, the height adjusting nut 43 engages with the inner wall of the inner cylinder. The inner cylinder 8 comprises an inner cylinder body, a first rolling bearing, a second rolling bearing, and a sliding bearing, wherein the sliding bearing engages internally with the connecting shaft 2. One end of the angle adjusting screw 52 is connected to the outer cylinder 7, and the other end engages with the angle adjusting nut 53, which is externally mounted on the adjusting bracket 54. One end of the adjusting bracket 54 is connected to the fixed bracket, and the other end is connected to the outer cylinder 7. The driving component 1 includes a motor, an output gear, and an angle sensor, wherein the output gear and the angle sensor are both fixedly connected to the motor output shaft; the motor housing is fixedly connected to the outer cylinder 7. One end of the fixed bracket is mounted on the outer cylinder 7, and the other end is connected to the adjusting bracket 54.

[0085] See Figure 5 , Figure 6 and Figure 7 The following examples illustrate the height adjustment, angle adjustment, and feel simulation:

[0086] The first electromagnet 311 and the second electromagnet 312 are not energized. At this time, the third gear 323 only meshes with the height adjustment transmission component 41 and is not meshed with the rotating component 61. The motor output gear meshes with the first gear 321, and the first gear 321 meshes with the height adjustment transmission component 41. Under control, the motor output torque is transmitted to the first gear 321 through the output gear. The first gear 321 transmits the torque to the height adjustment transmission component 41. The rotation of the height adjustment transmission component 41 drives the height adjustment screw 42 to rotate. The height adjustment screw 42 drives the height adjustment nut 43 to move axially along the inner column cylinder 8. The height adjustment nut 43 drives the connecting shaft 2 to move axially, and the connecting shaft 2 drives the steering wheel to move axially, thereby realizing the steering wheel height adjustment. By controlling the rotation direction of the motor, the steering wheel height can be adjusted in the opposite direction. By increasing the length of the guide mechanism between the height adjustment nut 43 and the inner column cylinder 8, the steering wheel height adjustment range can be changed, thereby realizing the steering wheel storage function.

[0087] When the first electromagnet 311 is energized, it drives the switching shaft 33 to move closer to the first electromagnet 311, which in turn drives the third gear 323, the first gear 321, and the second gear 322 to move synchronously toward the first electromagnet 311. The first reset member 34 is compressed synchronously, so that the switching component 3 is switched to angle adjustment: the second gear 322 meshes with the angle adjustment transmission member 51, the first gear 321 disengages from the height adjustment transmission member 41, and the first gear 321 continuously meshes with the output gear of the motor. Under control, the motor outputs torque, which is transmitted to the first gear 321 via the output gear. The first gear 321 drives the switching shaft 33 to rotate, which in turn drives the second gear 322. The second gear 322, through gear meshing, drives the angle adjustment transmission component 51 to rotate, which in turn drives the angle adjustment screw 52 to rotate. The rotation of the angle adjustment screw 52 drives the angle adjustment nut 53 to move axially, which in turn pushes the adjustment bracket 54 to move. The movement of the adjustment bracket 54 drives the outer column cylinder 7 to move around the rotation axis, which in turn drives the inner column cylinder 8 and the connecting shaft 2 to rotate synchronously. The connecting shaft 2 drives the steering wheel to rotate, thereby realizing the angle adjustment of the hand-feel simulation device assembly. By controlling the rotation direction of the motor, the steering wheel angle can be adjusted in the opposite direction. Through the control strategy, the first electromagnet 311 is de-energized, the electromagnet loses its magnetism, and the first reset component 34 springs back, pushing the switching shaft 33 back to its original position, thereby releasing the angle adjustment torque transmission.

[0088] When the second electromagnet 312 is energized, it drives the switching shaft 33 to move closer to the second electromagnet 312, which in turn drives the third gear 323, the first gear 321, and the second gear 322 to move synchronously toward the second electromagnet 312, and the second reset member 35 is compressed synchronously. The first gear 321 continuously meshes with the height adjustment transmission member 41, and the third gear 323 meshes with the rotating member 61. The third gear 323 continuously meshes with the height adjustment transmission member 41. Under control, the motor outputs torque, which is transmitted through the output gear to the first gear 321 and the third gear 323. The first gear 321 transmits torque to the height adjustment transmission member 41 through gear meshing, and the third gear 323 transmits torque to the rotating member 61 through gear meshing. The third gear 323 synchronously meshes with the height adjustment transmission member 41 and the rotating member 61, realizing the synchronous rotation of the height adjustment transmission member 41 and the rotating member 61. The height adjustment transmission component 41 rotates, driving the height adjustment screw 42 to move. The rotating component 61 is fixedly connected to the inner column cylinder 8. The height adjustment nut 43 is externally fitted with the guide groove of the inner column cylinder 8, and its inner diameter is fixedly connected to the connecting shaft 2. The rotation of the rotating component 61 drives the connecting shaft 2. The height adjustment transmission component 41 and the rotating component 61 rotate synchronously, so that the height adjustment nut 43 is stationary relative to the height adjustment screw 42, and the height adjustment nut 43 has no axial movement. This allows the motor torque to drive the connecting shaft 2 to rotate through the output gear, and the connecting shaft 2 to drive the steering wheel to rotate, thus realizing the output of motor torque to the steering wheel. By controlling the magnitude of the motor output torque, different steering effort simulations can be achieved.
