[0037] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below.

[0041] The present application provides a wire-controlled steering column and a vehicle.

[0042] The following is a description of the wire-controlled steering column provided in the present application.

[0043] See also Figure 1-Figure 3 , Figure 1 A top view of a wire-controlled steering column provided in some embodiments of the present application, Figure 2 A stereoscopic diagram of a wire-controlled steering column provided in some embodiments of the present application, Figure 3 The exploded view of the wire-controlled steering column provided in some embodiments of the present application. The wire-controlled steering column 100 may include a mounting bracket 1, a movable bracket 2, an axial adjustment mechanism 3, a column assembly 4, an angle adjustment mechanism 5 and a control assembly 6.

[0044] The mounting bracket 1 may have a mounting hole 11 , through which the mounting bracket 1 may be fixed to the vehicle.

[0045] The mounting bracket 1 may have a slideway 12 extending along the length direction of the mounting bracket 1. The movable bracket 2 is movably disposed in the slideway 12, so that the movable bracket 2 is movable relative to the mounting bracket 1, and the moving direction is the length direction of the mounting bracket 1.

[0046] Exemplarily, both sides of the mounting bracket 1 in the width direction may have a slide 12, and both ends of the mobile bracket 2 may extend into the slide 12, so that the slide 12 can support both ends of the mobile bracket 2, thereby helping to reduce the difficulty of assembly and also ensuring the reliability of movement.

[0047] Therefore, by setting up a mobile bracket 2, compared with the structure of multiple mobile brackets 2 in the related art, the width of the mobile bracket 2 can be reduced. For example, the width W2 of the mobile bracket 2 in the present application can be 119 mm, which can be reduced by about 35 mm compared with the structure of multiple mobile brackets 2, so that the width W1 of the mounting bracket 1 can be 170-185 mm, so that other components in the vehicle can have more layout space, which is beneficial to improving the user experience.

[0048] The axial adjustment mechanism 3 is disposed on the mounting bracket 1. The connection between the axial adjustment mechanism 3 and the mounting bracket 1 may be detachably connected, and the detachable connection may be achieved by fasteners, clamping, etc., so as to facilitate replacement and maintenance of the axial adjustment mechanism 3.

[0049] The orthographic projection of the axial adjustment mechanism 3 on the plane where the mounting bracket 1 is located is located within the outline of the mounting bracket 1 and does not overlap with the mounting hole 11. Therefore, the installation position of the axial adjustment mechanism 3 on the mounting bracket 1 can be staggered from the mounting hole 11, so that the size of the mounting bracket 1 in the width direction can be avoided to be too large, and further, the layout space of the vehicle's brake pedal, air conditioner and other components can be avoided to be reduced.

[0050] The axial adjustment mechanism 3 is connected to the movable bracket 2, and is used to drive the movable bracket 2 to move relative to the mounting bracket 1. Thus, the movable bracket 2 can be driven to move along the length direction by the axial adjustment mechanism 3.

[0051] The pipe column assembly 4 is rotatably arranged on the mobile bracket 2, so that the pipe column assembly 4 can rotate relative to the mobile bracket 2. The axial direction of the pipe column assembly 4 is in the same direction as the moving direction of the mobile bracket 2.

[0052] The angle adjustment mechanism 5 is disposed on the mobile bracket 2 and connected to the column assembly 4, and is used to drive the column assembly 4 to rotate relative to the mounting bracket 1. Therefore, by disposing the angle adjustment mechanism 5 on the mobile bracket 2, the volume of the wire-controlled steering column 100 can be reduced, so that the structural layout of the wire-controlled steering column 100 can be more reasonable. At the same time, the rotation of the column assembly 4 can also be realized.

[0053] The control assembly 6 may be arranged at one end of the column assembly 4 in the axial direction. The control assembly 6 may include a hand feel simulator and a control unit. Thus, the control assembly 6 may be arranged along the axial direction of the column assembly 4, thereby reducing the space occupied by the steer-by-wire column 100 in the height direction.

[0054] The control assembly 6 may have a communication interface 61. The communication interface 61 may be located on a side of the column assembly 4 away from the mobile bracket 2. Thus, the communication interface 61 may be prevented from occupying an axial dimension, thereby reducing the layout space of the wire-controlled steering column 100. It is also convenient for operators to connect the communication interface 61, thereby facilitating the assembly efficiency of the vehicle.

[0055] Thus, by movably arranging a movable bracket 2 in the slideway 12 of the mounting bracket 1, and making the orthographic projection of the axial adjustment mechanism 3 on the plane where the mounting bracket 1 is located not overlap with the mounting hole 11, it is possible to avoid the mounting bracket 1 being too large in the width direction, thereby meeting the layout requirements of other components such as the brake pedal and air conditioner of the vehicle (such as Figure 4 At the same time, by arranging the control assembly 6 at one end of the column assembly 4 in the axial direction and only providing one movable bracket 2, the space occupied by the wire-controlled steering column 100 in the height direction can be reduced, thereby realizing the arrangement of a head-up display 300 of a larger size (such as Figure 5 As shown), it is helpful to improve the user experience. In addition, by arranging the communication interface 61 on the side of the column assembly 4 away from the mobile bracket 2, the length dimension of the wire steering column 100 can be reduced. As a result, the height, width and length dimensions of the wire steering column 100 can be reduced, thereby reducing the layout space of the wire steering column 100, so that other components of the vehicle can have more layout space, which is helpful to improve the user experience.

[0056] See also Figure 3 and Figure 6 , Figure 6 Schematic diagram of a mounting bracket provided for some embodiments of the present application. In some embodiments, the mounting hole 11 may include two first mounting holes 111 and two second mounting holes 112 that are spaced apart. Specifically, the first mounting hole 111 and the second mounting hole 112 may be spaced apart in the length direction of the mounting bracket 1, the two first mounting holes 111 may be spaced apart in the width direction of the mounting bracket 1, and the two second mounting holes 112 may also be spaced apart in the width direction of the mounting bracket 1. Thus, the steering-by-wire column 100 may be fixed to the vehicle through the first mounting hole 111 and the second mounting hole 112, and the reliability of the steering-by-wire column 100 may also be improved.

[0057] A first reinforcing rib 13 and a second reinforcing rib 14 may be provided on a side of the mounting bracket 1 away from the mobile bracket 2. The first reinforcing rib 13 is located between the two first mounting holes 111, and the second reinforcing rib 14 is located between the two second mounting holes 112. The first reinforcing rib 13 may extend toward the first mounting holes 111, and the second reinforcing rib 14 may also extend toward the second mounting holes 112. This is beneficial to improving the mode of the mounting bracket 1, and can reduce the vibration of the wire-controlled steering column 100, thereby facilitating improving the structural strength of the mounting bracket 1.

[0058] Please continue reading Figure 1-Figure 3 In some embodiments, the mounting bracket 1 may further be provided with a third reinforcing rib 15. The third reinforcing rib 15 may be located between the first reinforcing rib 13 and the second reinforcing rib 14. This is beneficial to further improve the structural strength of the mounting bracket 1.

[0059] Exemplarily, the third reinforcing rib 15 may extend to the edge of the mounting bracket 1, thereby facilitating improving the structural strength of the mounting bracket 1. In addition, the first reinforcing rib 13, the second reinforcing rib 14 and the third reinforcing rib 15 may be hollowed out, which can reduce the weight of the mounting bracket 1 while ensuring the structural strength.

[0060] The third reinforcing rib 15 may be provided with a first through hole 151. The second reinforcing rib 14 may be provided with a second through hole 141. A slide rail 21 may be provided on the side of the mobile bracket 2 facing the mounting bracket 1. The slide rail 21 cooperates with the slideway 12. The first through hole 151 and the second through hole 141 are directly opposite to the slideway 12. Specifically, the orthographic projections of the first through hole 151 and the second through hole 141 on the mobile bracket 2 may be located in the slide rail 21, and the extension direction of the slide rail 21 is the same as the extension direction of the slideway 12. Thus, the structural strength of the mounting bracket 1 can be ensured. At the same time, the bearing can be arranged in the first through hole 151 and the second through hole 141, and can cooperate with the slide rail 21, so that the friction between the mobile bracket 2 and the mounting bracket 1 can be reduced through the slide rail 21, and the slide rail 21 also has a guiding function, so that the mobile bracket 2 can better cooperate with the mounting bracket 1, which is conducive to improving the reliability of the wire control steering column 100.

[0061] Please continue reading Figure 3 and Figure 6 In some embodiments, a side of the mounting bracket 1 facing the mobile bracket 2 may be provided with an avoidance groove 16. The avoidance groove 16 is directly opposite to the control assembly 6. The avoidance groove 16 is recessed in a direction away from the mobile bracket 2. Thus, interference between the mounting bracket 1 and the housing of the control assembly 6 can be avoided, which is beneficial to improving the reliability of the wire-controlled steering column 100.

[0062] See also Figure 6 and Figure 7 , Figure 7 Schematic diagram of a mobile bracket provided for some embodiments of the present application. In some embodiments, in the length direction of the wire steering column 100, the two opposite ends of the slide 12 may be provided with a first limiting groove 121. The first limiting groove 121 is connected to the slide 12. In the length direction of the wire steering column 100, the two opposite ends of the slide rail 21 are provided with a second limiting groove 211. The second limiting groove 211 is connected to the slide rail 21. Specifically, the extension direction of the first limiting groove 121 intersects with the extension direction of the slide 12, and the extension direction of the second limiting groove 211 intersects with the extension direction of the slide rail 21. Thus, the first limiting groove 121 and the second limiting groove 211 can play a limiting role in the movement of the mobile bracket 2, and the mobile bracket 2 can be prevented from swaying during the movement, which is beneficial to improve the reliability of the wire steering column 100.

[0063] Please continue reading Figure 3 , Figure 6 and Figure 7 In some embodiments, a first weight-reducing groove 17 may be provided on one side of the slideway 12 facing the column assembly 4. A second weight-reducing groove 22 may be provided on one side of the mobile bracket 2 facing the column assembly 4. Specifically, there may be a plurality of first weight-reducing grooves 17, which may be arranged at intervals in the extending direction of the slideway 12. There may also be a plurality of second weight-reducing grooves 22, which may be arranged at intervals in the length direction of the mobile bracket 2. Thus, the mounting bracket 1 and the mobile bracket 2 may be lightweight, which is beneficial to reducing the weight of the steer-by-wire column 100.

[0064] See also Figure 6-Figure 8 , Figure 8 Schematic diagram of an axial adjustment mechanism provided for some embodiments of the present application. In some embodiments, the axial adjustment mechanism 3 may include an axial drive assembly 31, a first fixing bracket 32, and a buffer belt 33. The axial drive assembly 31 is connected to the mounting bracket 1. Exemplarily, the mounting bracket 1 may be provided with an axial fixing ear 18, and the axial drive assembly 31 may be connected to the mounting bracket 1 through the axial fixing ear 18.

[0065] The first fixed bracket 32 ​​is slidably connected to the mounting bracket 1, and the axial drive assembly 31 is used to drive the first fixed bracket 32 ​​to slide relative to the mounting bracket 1. Specifically, the axial drive assembly 31 can drive the first fixed bracket 32 ​​to slide along the length direction of the mounting bracket 1, and there is a gap between the installation position of the axial drive assembly 31 and the installation position of the first fixed bracket 32. The axial drive assembly 31 is a component that can realize linear motion, such as a cylinder, an electric push rod, a lead screw, etc.

[0066] The buffer belt 33 is connected to the first fixing bracket 32. The buffer belt 33 can be connected to the first fixing bracket 32 ​​by a fastener.

[0067] The mobile bracket 2 is provided with a connecting shaft 332. The buffer belt 33 and the first fixed bracket 32 ​​can enclose a receiving groove 331, one end of the receiving groove 331 has an opening, and the other end abuts the connecting shaft 332. Specifically, the buffer belt 33 can be formed into a "U" shape, one end of the buffer belt 33 can be connected to the bottom wall of the first fixed bracket 32 ​​by a fastener, and the other end is bent in the direction close to the mounting bracket 1, so that there is a spacing between the buffer belt 33 and the first fixed bracket 32, so that the buffer belt 33 and the first fixed bracket 32 ​​enclose a receiving groove 331, and the extension direction of the receiving groove 331 is the same as the length direction of the mounting bracket 1. The mobile bracket 2 can have a buffer belt fixing ear 23, and the buffer belt fixing ear 23 can be located in the middle of the mobile bracket 2. One end of the connecting shaft 332 can be connected to the buffer belt fixing ear 23, and the other end of the connecting shaft 332 can enter the receiving groove 331 through the opening. When the axial drive assembly 31 drives the first fixed bracket 32 ​​to move, the inner wall of the accommodating groove 331 abuts against the connecting shaft 332, and the connecting shaft 332 can be driven to move with the first fixed bracket 32, thereby driving the movable bracket 2 to move relative to the mounting bracket 1.

[0068] According to the wire-controlled steering column 100 of the embodiment of the present application, a buffer belt 33 is provided on the first fixed bracket 32, so that the buffer belt 33 and the first fixed bracket 32 ​​enclose a receiving groove 331, and the movable bracket 2 is abutted against one end of the receiving groove 331 through the connecting shaft 332. When the axial drive component 31 drives the first fixed bracket 32 ​​to move, the movable bracket 2 can be driven to move relative to the mounting bracket 1, and the connecting shaft 332 can be covered by the buffer belt 33, which can reduce the collision between the connecting shaft 332 and other components, thereby avoiding abnormal noise when the axial drive component 31 drives the movable bracket 2 to move, which is beneficial to improving the user experience.

[0069] In order to balance the weight of the buffer belt fixing ear 23 , a third weight-reducing groove 25 may be provided on the movable bracket 2 , and the third weight-reducing groove 25 may be directly opposite to the axial fixing ear 18 .

[0070] Please continue reading Figure 6-Figure 8 In some embodiments, the axial drive assembly 31 may include an axial drive motor 311, a first lead screw 312, and a first slider 313. The axial drive motor 311 is connected to the mounting bracket 1 and is used to drive the first lead screw 312 to rotate. Specifically, the axial drive motor 311 may be connected to the mounting bracket 1 through the axial fixing ear 18.

[0071] The first fixed bracket 32 ​​can be connected to the first lead screw 312 by transmission through the first slider 313. Exemplarily, the first slider 313 is sleeved on the first lead screw 312. The first fixed bracket 32 ​​may include a first fixed portion 321 and a second fixed portion 322. The first fixed portion 321 and the second fixed portion 322 may be connected by fasteners. The first fixed portion 321 and the second fixed portion 322 may be located at opposite ends of the first slider 313 and abut against the first slider 313, so that they can be connected to the first slider 313 by crimping. Among them, the first fixed portion 321 can cover the first slider 313, so that the first slider 313 can be protected. As a result, the installation difficulty of the axial drive assembly 31 can be reduced, which is conducive to improving assembly efficiency. At the same time, the use of materials can be reduced, and it is conducive to reducing weight.

[0072] The outer periphery of the first lead screw 312 may be covered with a protective shell 314. Thus, it is possible to prevent peripheral wire harnesses and other parts from getting involved and causing failures, thereby facilitating the improvement of the safety and reliability of the operation of the wire-controlled steering column 100.

[0073] Please continue reading Figure 6-Figure 8 , exemplarily, in the height direction of the wire steering column 100, a guide bolt 323 may be provided on one side of the first fixed bracket 32, and an anti-wear pad 324 may be provided on the other side. A guide slot 19 may be provided on the mounting bracket 1. The guide slot 19 extends along the length direction of the mounting bracket 1. The guide bolt 323 is slidably connected to the guide slot 19. Specifically, the guide bolt 323 may include a bolt head and a bolt column, and the size of the bolt head is larger than the size of the bolt column. When the guide bolt 323 is matched with the guide slot 19, the bolt column is located in the guide slot 19, and the bolt head is located outside the guide slot 19, so that the guide bolt 323 can be prevented from falling during the sliding process. At the same time, during the sliding process of the first fixed bracket 32, the anti-wear pad 324 on the other side of the first fixed bracket 32 ​​can contact the bottom wall of the guide slot 19, and the anti-wear pad 324 can prevent the first fixed bracket 32 ​​from making abnormal noise when moving.

[0074] Thus, the guide bolt 323 can guide the movement of the first fixing bracket 32, thereby ensuring the reliability of the movement. The anti-friction pad 324 can prevent the first fixing bracket 32 ​​from making abnormal noise when moving, thereby improving the user experience.

[0075] Exemplarily, the portion of the first fixing bracket 32 ​​where the guide bolt 323 is disposed may protrude outward, so that the guide bolt 323 may better cooperate with the guide slot 19 .

[0076] Therefore, when the wire-controlled steering column 100 realizes axial movement, the axial drive motor 311 is used to drive the first screw 312 to rotate, and the first screw 312 drives the first slider 313 to move, thereby driving the first fixed bracket 32 ​​connected to the first slider 313 to move, and through the cooperation between the guide bolt 323 and the guide groove 19, the first fixed bracket 32 ​​slides along the extension direction of the guide groove 19, thereby driving the movable bracket 2 to realize axial movement.

[0077] See also Figure 7-10 , Fig. 9 A schematic diagram of an angle adjustment mechanism provided in some embodiments of the present application, Fig.10 Schematic diagram of a pipe column assembly provided for some embodiments of the present application. In some embodiments, the angle adjustment mechanism 5 may include an angle adjustment component 51 and a second fixing bracket 52. The angle adjustment component 51 is connected to the pipe column assembly 4. Specifically, the pipe column assembly 4 may be provided with an angle adjustment fixing ear 411, and the angle adjustment component 51 may be connected to the pipe column assembly 4 through the angle adjustment fixing ear 411.

[0078] Exemplarily, the angle adjustment assembly 51 may include an angle adjustment motor 511, a second lead screw 512, and a second slider 513. The angle adjustment motor 511 may be connected to the column assembly 4 via the angle adjustment fixing ear 411, and is used to drive the second lead screw 512 to rotate, the second slider 513 is connected to the second lead screw 512, and the second fixed bracket 52 is connected to the second slider 513, and the second fixed bracket 52 may be driven to move via the angle adjustment motor 511.

[0079] It should be noted that the angle adjustment component 51 may also be other components that drive linear motion, and this application does not impose any limitation on this.

[0080] The angle adjustment assembly 51 is used to drive the second fixed bracket 52 to rotate relative to the mobile bracket 2. The second fixed bracket 52 may be provided with a first fixed shaft 521, a second fixed shaft 522 and a pin shaft 523. The first fixed shaft 521 is connected to the pipe column assembly 4, the second fixed shaft 522 is connected to the mobile bracket 2, and the pin shaft 523 is located between the first fixed shaft 521 and the second fixed shaft 522, and abuts against the pipe column assembly 4. Specifically, the first fixed shaft 521, the pin shaft 523 and the second fixed shaft 522 are arranged at intervals, the pipe column assembly 4 may be provided with a first fixed ear 412 connected to the first fixed shaft 521, the mobile bracket 2 may be provided with a second fixed ear 24 connected to the second fixed shaft 522, and the pin shaft 523 abuts against the outer shell of the pipe column assembly 4. In this way, the gap can be eliminated to ensure the stability and reliability of the rotation of the pipe column assembly 4.

[0081] When the wire-controlled steering column 100 is rotated, the angle adjustment motor 511 is used to drive the second lead screw 512 to rotate, and the second lead screw 512 drives the second slider 513 to move, thereby driving the second fixed bracket 52 connected to the second slider 513 to move, and since the first fixed shaft 521 of the second fixed bracket 52 is connected to the column assembly 4, the second fixed shaft 522 is connected to the mobile bracket 2, and the column assembly 4 is rotatably arranged on the mobile bracket 2, the second fixed bracket 52 can rotate relative to the mobile bracket 2, and the rotation center of the second fixed bracket 52 is located at the second fixed shaft 522. In the height direction of the wire-controlled steering column 100, the second fixed bracket 52 can rotate upward or downward relative to the mobile bracket 2, so that the column assembly 4 can be driven to rotate through the first fixed shaft 521.

[0082] Exemplarily, the second fixing bracket 52 may include a third fixing portion 524 and a fourth fixing portion 525. The first fixing shaft 521, the second fixing shaft 522 and the pin 523 are disposed on the third fixing portion 524. The third fixing portion 524 and the fourth fixing portion 525 may be connected by fasteners to compress the second slider 513. A weight-reducing hole 5241 may be provided on the third fixing portion 524. Thus, the weight of the second fixing bracket 52 may be reduced, thereby facilitating the weight reduction of the steer-by-wire column 100.

[0083] Please continue reading Fig.10 , exemplarily, the column assembly 4 may include a column barrel 41 and a shaft head 42. One end of the column barrel 41 is connected to the control assembly 6, and the other end is connected to the shaft head 42. Among them, the column barrel 41 may be provided with a convex rib 413, which is beneficial to improve the structural strength of the column barrel 41, and further to improve the mode of the column assembly 4. The column barrel 41 may also be provided with a combination switch fixing groove 414, which is beneficial to improve the assembly efficiency.

[0084] The control assembly 6 may be provided with a pivot shaft 62, and the mobile bracket 2 may be provided with a third fixing ear 26. The pivot shaft 62 is connected to the third fixing ear 26. This is conducive to further improving the stability and reliability of the rotation of the column assembly 4. In addition, the arrangement of the pivot shaft 62 and the first fixing ear 412 can avoid adding an additional bracket, thereby facilitating the reduction of the height dimension of the steer-by-wire column 100, and also reducing the weight of the steer-by-wire column 100.
